    OBJECTIVE: To analyze the relationship between exposure to air pollutants and hospitalizations due to pneumonia in children of Sorocaba, São Paulo, Brazil. METHODS: Time series ecological study, from 2007 to 2008. Daily data were obtained from the State Environmental Agency for Pollution Control for particulate matter, nitric oxide, nitrogen dioxide, ozone, besides air temperature and relative humidity. The data concerning pneumonia admissions were collected in the public health system of Sorocaba. Correlations between the variables of interest using Pearson cofficient were calculated. Models with lags from zero to five days after exposure to pollutants were performed to analyze the association between the exposure to environmental pollutants and hospital admissions. The analysis used the generalized linear model of Poisson regression, being significant p<0.05. RESULTS: There were 1,825 admissions for pneumonia, with a daily mean of 2.5±2.1. There was a strong correlation between pollutants and hospital admissions, except for ozone. Regarding the Poisson regression analysis with the multi-pollutant model, only nitrogen dioxide was statistically significant in the same day (relative risk - RR=1.016), as well as particulate matter with a lag of four days (RR=1.009) after exposure to pollutants. CONCLUSIONS: There was an acute effect of exposure to nitrogen dioxide and a later effect of exposure to particulate matter on children hospitalizations for pneumonia in Sorocaba. PMID:24473956

    There are scarce studies of time series that analysed the short-term association between emergency hospital admissions due to Alzheimer's disease (AD) and environmental factors. The objective is to analyse the effect of heat waves, noise and air pollutants on urgent hospital admissions due to AD in Madrid. Longitudinal ecological time series study was performed. The dependent variable was the emergency AD hospital admissions occurred in Madrid during the period 2001-2009. Independent variables were: Daily mean concentrations (μg/m3) of air pollutants (PM 2.5 and PM 10 ; O3 and NO2); maximum daily temperature (°C) and daily and night noise levels (dB(A)). Relative Risk (RR) for an increment in interquartile range, and Attributable Risk (AR) values were calculated through GLM with Poisson link. Our findings indicated that only PM 2.5 concentrations at lag 2 with a RR: 1.38 (95% CI: 1.15-1.65); AR 27.5% (95% CI: 13.0-39.4); and heat wave days at lag 3 with a RR: 1.30 (95% CI: 1.12-1.52); AR 23.1% (95% CI: 10.7-34.2) were associated with AD hospital admissions. A reduction in AD patients' exposure levels to PM 2.5 and special care of such patients during heat wave periods could result in a decrease in both emergency AD admissions and the related health care costs.

    Norovirus generally causes a mild illness in the community. However, modeling routine hospital admission statistics, we estimate that approximately 3000 norovirus admissions to English hospitals occur per year, accounting for 0.3% and 0.1% of emergency admissions among elderly and adult patients, respectively, at times of peak activity. These admissions pose a risk for subsequent nosocomial infection outbreaks.

    Given that respiratory diseases are a major cause of hospitalization in children, the objectives of this study are to estimate the role of exposure to fine particulate matter in hospitalizations due to pneumonia and a possible reduction in the number of these hospitalizations and costs. An ecological time-series study was developed with data on hospitalization for pneumonia among children under 10 years of age living in São José do Rio Preto, state of São Paulo, using PM2.5 concentrations estimated using a mathematical model. We used Poisson regression with a dependent variable (hospitalization) associated with PM2.5 concentrations and adjusted for effective temperature, seasonality and day of the week, with estimates of reductions in the number of hospitalizations and costs. 1,161 children were admitted to hospital between October 1st, 2011, and September 30th, 2013; the average concentration of PM2.5 was 18.7 µg/m3 (≈32 µg/m3 of PM10) and exposure to this pollutant was associated with hospitalization four and five days after exposure. A 10 µg/m3 decrease in concentration would imply 256 less hospital admissions and savings of approximately R$ 220,000 in a medium-sized city.

    Spain has one of the highest proportions of dementia in the world among the population aged 60 years or over. Recent studies link various environmental factors to neurocognitive-type diseases. This study sought to analyse whether urban risk factors such as traffic noise, pollutants and heat waves might have a short-term impact on exacerbation of symptoms of dementia, leading to emergency hospital admission. We conducted a longitudinal ecological time-series study, with the dependent variable being the number of daily dementia-related emergency (DDE) hospital admissions to Madrid municipal hospitals (ICD-10 codes 290.0-290.2, 290.4-290.9, 294.1-294) from 01 to 01-2001 to 31-12-2009, as obtained from the Hospital Morbidity Survey (National Statistics Institute). The measures used were as follows: for noise pollution, Leqd, equivalent diurnal noise level (from 8 to 22h), and Leqn, equivalent nocturnal noise level (from 22 to 8h) in dB(A); for chemical pollution, mean daily NO2, PM2.5, PM1 as provided by the Madrid Municipal Air Quality Monitoring Grid; and lastly, maximum daily temperature (°C), as supplied by the State Meteorological Agency. Scatterplot diagrams were plotted to assess the type of functional relationship existing between the main variable of analysis and the environmental variables. The lags of the environmental variables were calculated to analyse the timing of the effect. Poisson regression models were fitted, controlling for trends and seasonalities, to quantify relative risk (RR). During the study period, there were 1175 DDE hospital admissions. These admissions displayed a linear functional relationship without a threshold in the case of Leqd. The RR of DDE admissions was 1.15 (1.11-1.20) for an increase of 1dB in Leqd, with impact at lag 0. In the case of maximum daily temperature, there was a threshold temperature of 34°C, with an increase of 1°C over this threshold posing an RR of 1.19 (1.09-1.30) at lag 1.

    To determine whether socio-economic differences in hospital admissions of adolescents and young adults are related to differences in intelligence. . Retrospective cohort study. The data were derived from a group of 10,231 young adults and adolescents who were followed for a total of 47,212 person years with regard to their hospital admissions. Intelligence was measured in the first year of secondary school by 2 non-verbal intelligence tests for fluid intelligence. Data from hospital admissions were matched to a large-scale educational and occupational cohort. Data were analysed with Cox proportional hazards analysis. Intelligence was not found to be related to hospital admissions. However, a low occupational and educational level of the young adults or their parents, was strongly related to heightened risk for hospital admissions. In particular, the low socio-economic status of a respondent was associated with heightened risk for hospital admissions due to accidents (relative risk: 3.49; 95% confidence interval: 1.91-6.39). The small extent to which the socio-economic differences in hospital admissions seem to be based upon fluid intelligence, at least in adolescents and young adults, as well as the heightened risks of hospital admissions in lower socio-economic status groups and the associated high costs for health care legitimise further study of the determinants of these differences.

    In order to assess the effect of air pollution on pediatric respiratory morbidity, we carried out a time series study using daily levels of PM10, SO2, NO2, ozone, and CO and daily numbers of pediatric respiratory emergency room visits and hospital admissions at the Children's Institute of the University of Sao Paulo Medical School, from August 1996 to August 1997. In this period there were 43,635 hospital emergency room visits, 4534 of which were due to lower respiratory tract disease. The total number of hospital admissions was 6785, 1021 of which were due to lower respiratory tract infectious and/or obstructive diseases. The three health end-points under investigation were the daily number of emergency room visits due to lower respiratory tract diseases, hospital admissions due to pneumonia, and hospital admissions due to asthma or bronchiolitis. Generalized additive Poisson regression models were fitted, controlling for smooth functions of time, temperature and humidity, and an indicator of weekdays. NO2 was positively associated with all outcomes. Interquartile range increases (65.04 microg/m3) in NO2 moving averages were associated with an 18.4% increase (95% confidence interval, 95% CI = 12.5-24.3) in emergency room visits due to lower respiratory tract diseases (4-day moving average), a 17.6% increase (95% CI = 3.3-32.7) in hospital admissions due to pneumonia or bronchopneumonia (3-day moving average), and a 31.4% increase (95% CI = 7.2-55.7) in hospital admissions due to asthma or bronchiolitis (2-day moving average). The study showed that air pollution considerably affects children's respiratory morbidity, deserving attention from the health authorities.

    New patterns in epidemiological characteristics of people living with HIV infection (PLWH) and the introduction of Highly Active Antiretroviral Therapy (HAART) have changed the profile of hospital admissions in this population. The aim of this study was to evaluate trends in hospital admissions, re-admissions, and mortality rates in HIV patients and to analyze the role of HCV co-infection. A retrospective cohort study conducted on all hospital admissions of HIV patients between 1993 and 2013. The study time was divided in two periods (1993-2002 and 2003-2013) to be compared by conducting a comparative cross-sectional analysis. A total of 22,901 patient-years were included in the analysis, with 6917 hospital admissions, corresponding to 1937 subjects (75% male, mean age 36±11 years, 37% HIV/HCV co-infected patients). The median length of hospital stay was 8 days (5-16), and the 30-day hospital re-admission rate was 20.1%. A significant decrease in hospital admissions related with infectious and psychiatric diseases was observed in the last period (2003-2013), but there was an increase in those related with malignancies, cardiovascular, gastrointestinal, and chronic respiratory diseases. In-hospital mortality remained high (6.8% in the first period vs. 6.3% in the second one), with a progressive increase of non-AIDS-defining illness deaths (37.9% vs. 68.3%, P<.001). The admission rate significantly dropped after 1996 (4.9% yearly), but it was less pronounced in HCV co-infected patients (1.7% yearly). Hospital admissions due to infectious and psychiatric disorders have decreased, with a significant increase in non-AIDS-defining malignancies, cardiovascular, and chronic respiratory diseases. In-hospital mortality is currently still high, but mainly because of non-AIDS-defining illnesses. HCV co-infection increased the hospital stay and re-admissions during the study period.

    One quarter of pediatric hospitalizations begin as direct admissions, defined as hospitalization without receiving care in the hospital's emergency department (ED). Direct admission rates are highly variable across hospitals, yet previous studies have not examined reasons for this variation. We aimed to determine the relationships between hospital and community factors and pediatric direct admission rates, and to evaluate the degree to which these characteristics explain variation in risk-adjusted direct admission rates. We conducted a cross-sectional study of the Healthcare Cost and Utilization Project's Kids Inpatient Database, American Hospital Association Database, and Area Health Resource File, including children <18 years of age who were admitted for a medical hospitalization in states contributing data to all data sets. Using hierarchical generalized linear modeling, we generated risk-adjusted direct admission rates and used generalized linear models to assess the association of hospital and community characteristics with these risk-adjusted rates. We included 211,458 children discharged from 933 hospitals and 26 states; 20.2% were admitted directly. One-fifth of the variance in risk-adjusted direct admission rates was attributed to observed hospital and community factors. The greatest proportion of this explained variance was related to ED volume (37%), volume of pediatric hospitalizations (27%), and size of the pediatrician workforce (12%). Direct admission rates were associated with several hospital and community characteristics, but the majority of variation in hospitals' direct admission rates was not explained by these factors. These findings suggest opportunities for diverse hospital types to develop the infrastructure and communication systems necessary to support pediatric direct admissions.

    We use an event study approach to examine the economic consequences of hospital admissions for adults in two datasets: survey data from the Health and Retirement Study, and hospitalization data linked to credit reports. For non-elderly adults with health insurance, hospital admissions increase out-of-pocket medical spending, unpaid medical bills and bankruptcy, and reduce earnings, income, access to credit and consumer borrowing. The earnings decline is substantial compared to the out-of-pocket spending increase, and is minimally insured prior to age-eligibility for Social Security Retirement Income. Relative to the insured non-elderly, the uninsured non-elderly experience much larger increases in unpaid medical bills and bankruptcy rates following a hospital admission. Hospital admissions trigger less than 5 percent of all bankruptcies. PMID:29445246

    Falls among elderly people causing hospitalization are considered one of the most important public health problems. Our objective was to analyse fall related hospital admissions among seniors (> or = 65 years old) in Poland in 2010. The analyses were conducted with regard to gender, place of residence and age. Additionally, the health consequences of falls among elderly people were studied. Injuries and other consequences of external causes, were expressed in the form of three-character ICD-10 codes representing the underlying disease (S00-T98). Data on hospital admissions resulting from falls among seniors were obtained from the database held at the Department - Centre for Monitoring and Analyses of Population Health Status and Health Care System by the National Institute of Public Health - National Institute of Hygiene. Analysis has shown that the hospitalization ratio due to falls is much higher for women than for men. On average, 1 024 per 100 000 women are hospitalized due to a fall, while the number for men is 649. For every analysed age group women are at a higher risk of hospitalization due to a fall than men. In 2010 nearly 70% of hospital admissions of elderly people due to a fall were caused by a fall on the same level as a result of tripping or slipping (31 712 hospitalizations). No differences in relation to gender were observed. Risk of hospitalization due to a fall increases with age. For people over 80 years of age it is 2.5 times higher than for people in the 65-69 age group (1 459 and 570 per 100 000 respectively). It was observed that the length of hospital stay increases with age. There were no significant differences between the number of hospitalizations depending on the place of residence. The analysis showed that differences in the length of stay for women and men are statistically significant. However, there was no statistically significant difference between the lengths of stay depending on a place of residence. Almost one-third of

    A retrospective study was performed between January 2007 and December 2012 to assess the admission rates of newborns due to episodes of cyanosis Retrospective study that included all the newborns hospitalized with episodes of cyanosis between January 2007 and December 2012. In them were employed two study protocols that considered first and second line tests, the latter in view of recurrence of events. The first line protocol considered general biochemical tests, chest x-ray and echocardiography in selected cases, while the second line protocol included electroencephalogram, electrocardiogram, nuclear magnetic resonance of the brain, expanded metabolic screening, pyruvic acid, lactic acid, and in case of seizures, cytochemical, and culture of cerebrospinal fluid (CSF) and PCR (polymerase chain reaction) for herpes. A total of 98 (2.8%) out of 3,454 newborns were admitted due to episodes of cyanosis. Gestational age: 37.8+1.4 weeks, birth weight: 3,145+477 g. Maternal age: 32+4.8 years. Disease was present in 19.4% of mothers; gestational diabetes (8.1%), pregnancy induced hypertension (5.1%), intrahepatic cholestasis (3.1%), and intrauterine growth retardation (3.1%). Gender: 48.8% male, 51.2% female (NS). Birth: caesarean section, 68.4%, and vaginal delivery, 31.6%. Age on admission 1.9+1.4 days. Hospital stay: 4.2+4.2 days. First line tests were performed in 100% of patients with 39.8% fulfilling the criteria for second line study. A condition was detected in 21.4%, with convulsive syndrome was the most frequent (33%). Newborns with an identified condition had 3.8+2.7 episodes versus 1.5+2,4 in those without diagnosis (NS). A home oxygen monitor was given to 15.4%. There were no re-admissions. Most newborns admitted due to cyanosis are discharged with a condition of unknown origin. In this study, convulsive syndrome was the most frequent cause.

    The aim of this study was to explore the variability in hospital admissions of patients with spondyloarthritis (SpA) in Spain, and the centre factors that may influence that variability. Descriptive cross-sectional study, part of the emAR II study, performed in Spain (2009-2010). Health records of patients with a diagnosis of SpA and at least one visit to the rheumatology units within the previous 2 years were reviewed. Variables related to hospital admissions, to the SpA, and to the patient and centre were collected. A multilevel logistic regression analysis of random intercept with non-random slopes was performed to assess variability between centres. From 45 centres, 1168 patients' health records were reviewed. Main SpA forms were ankylosing spondylitis (55.2 %) and psoriatic arthritis (22.2 %). A total of 248 admissions were registered for 196 patients (19.2 %, n = 1020). An adjusted variability of 17.6 % in hospitalizations between centres was noted. The following hospital-related factors showed a significant association with admissions: the total number of admissions of the centre, the existence of electronic admission, and the availability of ultrasound in rheumatology. However, these factors only explained 42.9 % of the inter-centre variability. The risk of a patient with SpA of being admitted could double (median OR 2.09), depending on the hospital where the patient was being managed. Hospital admissions of patients with SpA varied between hospitals due to centre characteristics. Further studies are needed to ascertain which specific factors may be causing the variation, as studied variables explained less than half of the variability.

Cross-sectional study based on data from 33,212 hospital admissions in adults over 60 years in the city of São Paulo, southeastern Brazil, from 2003 to 2007. The association between atmospheric variables from Congonhas airport and bioclimatic index, Physiological Equivalent Temperature, was analyzed according to the district's socioenvironmental profile. Descriptive statistical analysis and regression models were used. There was an increase in hospital admissions due to circulatory diseases as average and lowest temperatures decreased. The likelihood of being admitted to the hospital increased by 12% with 1ºC decrease in the bioclimatic index and with 1ºC increase in the highest temperatures in the group with lower socioenvironmental conditions. The risk of admission due to respiratory diseases increased with inadequate air quality in districts with higher socioenvironmental conditions. The associations between morbidity and climate variables and the comfort index varied in different groups and diseases. Lower and higher temperatures increased the risk of hospital admission in the elderly. Districts with lower socioenvironmental conditions showed greater adverse health impacts.

    Exposure to particulate matter (PM) is associated with hospitalizations due to respiratory diseases among children. An ecological time series study was carried out to identify the role of coarse fractions of particulate matter (PM10-2.5) in hospitalizations among children up to 10 years of age, in Piracicaba (SP) in the year 2015. A generalized additive model of Poisson regression was used to estimate the risk of hospitalization due to acute laryngitis and tracheitis, pneumonia, bronchitis, bronchiolitis and asthma. Lags of 0 to 7 days were considered, and the model was adjusted for the temperature and relative humidity of the air and controlled for short and long-term exposure. Proportional attributable ratios, population-attributable fractions and hospital costs were calculated with increasing concentrations of these pollutants. 638 hospitalizations were evaluated during this period, with a mean of 1.75 cases per day (standard deviation, SD = 1.86). The daily averages were 22.45 µg/m3 (SD = 13.25) for the coarse fraction (PM10-2.5) and 13.32 µg/m3 (SD = 6.38) for the fine fraction. Significant risks of PM10-2.5 exposure were only observed at lag 0, with relative risk (RR) = 1.012, and at lag 6, with RR = 1.011. An increase of 5 µg/m3 in the coarse fraction concentration implied an increase in the relative risk of hospitalizations of up to 4.8%, with an excess of 72 hospitalizations and excess expenditure of US$ 17,000 per year. This study showed the impact of coarse-fraction exposure on hospital admissions among children due to respiratory diseases.

    Various fractions of particulate matter have been associated with increased mortality and morbidity. The purpose of our study is to analyze the associations between concentrations of PM2.5, PM2.5–10, PM10 and their chemical constituents (soluble ions) with hospital admissions due to circulatory and respiratory diseases among the elderly in a medium-sized city in Brazil. A time series study was conducted using Poisson regression with generalized additive models adjusted for confounders. Statistically significant associations were identified between PM10 and PM2.5–10 and respiratory diseases. Risks of hospitalization increased by 23.5% (95% CI: 13.5; 34.3) and 12.8% (95% CI: 6.0; 20.0) per 10 μg/m3 of PM2.5-10 and PM10, respectively. PM2.5 exhibited a significant association with circulatory system diseases, with the risk of hospitalization increasing by 19.6% (95% CI: 6.4; 34.6) per 10 μg/m3. Regarding the chemical species; SO42−, NO3−, NH4+ and K+ exhibited specific patterns of risk, relative to the investigated outcomes. Overall, SO42− in PM2.5–10 and K+ in PM2.5 were associated with increased risk of hospital admissions due to both types of diseases. The results agree with evidence indicating that the risks for different health outcomes vary in relation to the fractions and chemical composition of PM10. Thus, PM10 speciation studies may contribute to the establishment of more selective pollution control policies. PMID:27669280

    Background Accidental non-fire-related (ANFR) carbon monoxide (CO) poisoning is a cause of fatalities and hospital admissions. This is the first study that describes the characteristics of ANFR CO hospital admissions in England. Methods Hospital Episode Statistics (HES) inpatient data for England between 2001 and 2010 were used. ANFR CO poisoning admissions were defined as any mention of ICD-10 code T58: toxic effect of CO and X47: accidental poisoning by gases or vapours, excluding ICD-10 codes potentially related to fires (X00-X09, T20-T32 and Y26). Results There were 2463 ANFR CO admissions over the 10-year period (annual rate: 0.49/100 000); these comprised just under half (48.7%) of all non-fire-related (accidental and non-accidental) CO admissions. There was seasonal variability, with more admissions in colder winter months. Higher admission rates were observed in the north of England. Just over half (53%) of ANFR admissions were male, and the highest rates of ANFR admissions were in those aged >80 years. Conclusion The burden of ANFR CO poisoning is preventable. The results of this study suggest an appreciable burden of CO and highlight differences that may aid targeting of public health interventions. PMID:25755248

    Background While morbidity outcomes for major disease categories during extreme heat have received increasing research attention, there has been very limited investigation at the level of specific disease subcategories. Methodology/Principal Findings We analyzed daily hospital admissions for cardiovascular (CVD), respiratory (RD), genitourinary (GU) and mental diseases (MD), diabetes (DIA), dehydration (DEH) and ‘the effects of heat and light’ (HEAT) in Sydney between 1991 and 2009. We further investigated the sensitivity to heat of subcategories within the major disease groups. We defined hot days as those with temperatures in the 95th and 99th percentiles within the study period. We applied time-stratified case-crossover analysis to compare the hospital admissions on hot days with those on non-hot days matched by day of the week. We calculated the odds ratios (OR) of admissions between the two types of days, accounting for other environmental variables (relative humidity, ozone and particulate matter) and non-environmental trends (public and school holidays). On hot days, hospital admissions increased for all major categories except GU. This increase was not shared homogeneously across all diseases within a major category: within RD, only ‘other diseases of the respiratory system’ (includes pleurisy or empyema) increased significantly, while admissions for asthma decreased. Within MD, hospital admissions increased only for psychoses. Admissions due to some major categories increased one to three days after a hot day (e.g., DIA, RD and CVD) and on two and three consecutive days (e.g., HEAT and RD). Conclusions/Significance High ambient temperatures were associated with increased hospital admissions for several disease categories, with some within-category variation. Future analyses should focus on subgroups within broad disease categories to pinpoint medical conditions most affected by ambient heat. PMID:23408986

There were 2463 ANFR CO admissions over the 10-year period (annual rate: 0.49/100 000); these comprised just under half (48.7%) of all non-fire-related (accidental and non-accidental) CO admissions. There was seasonal variability, with more admissions in colder winter months. Higher admission rates were observed in the north of England. Just over half (53%) of ANFR admissions were male, and the highest rates of ANFR admissions were in those aged >80 years. The burden of ANFR CO poisoning is preventable. The results of this study suggest an appreciable burden of CO and highlight differences that may aid targeting of public health interventions. © The Author 2015.

    Background Rotavirus is the most common cause of severe gastroenteritis among young children in Spain and worldwide. We evaluated hospitalizations due to community and hospital-acquired rotavirus gastroenteritis (RVGE) and estimated related costs in children under 5 years old in Catalonia, Spain. Results We analyzed hospital discharge data from the Catalan Health Services regarding hospital admissions coded as infectious gastroenteritis in children under 5 for the period 2003-2008. In order to estimate admission incidence, we used population estimates for each study year published by the Statistic Institut of Catalonia (Idescat). The costs associated with hospital admissions due to rotavirus diarrhea were estimated for the same years. A decision tree model was used to estimate the threshold cost of rotavirus vaccine to achieve cost savings from the healthcare system perspective in Catalonia. From 2003 through 2008, 10655 children under 5 years old were admitted with infectious gastroenteritis (IGE). Twenty-two percent of these admissions were coded as RVGE, yielding an estimated average annual incidence of 104 RVGE hospitalizations per 100000 children in Catalonia. Eighty seven percent of admissions for RVGE occurred during December through March. The mean hospital stay was 3.7 days, 0.6 days longer than for other IGE. An additional 892 cases of presumed nosocomial RVGE were detected, yielding an incidence of 2.5 cases per 1000 child admissions. Total rotavirus hospitalization costs due to community acquired RVGE for the years 2003 and 2008 were 431,593 and 809,224 €, respectively. According to the estimated incidence and hospitalization costs, immunization would result in health system cost savings if the cost of the vaccine was 1.93 € or less. At a vaccine cost of 187 € the incremental cost per hospitalization prevented is 195,388 € (CI 95% 159,300; 238,400). Conclusions The burden of hospitalizations attributable to rotavirus appeared to be lower in

    The obesity pandemic together with the influenza pandemic could lead to a significant burden of disease. The body mass index (BMI) does not discriminate obesity appropriately. The CUN-BAE has recently been used as an estimate of body fatness for Caucasians, including BMI, gender, and age. The aim of this study is to assess the population attributable fraction of hospital admissions due to influenza, due to the body fatness measured with the BMI, and the CUN-BAE. A multicentre study was conducted using matched case-controls. Cases were hospital admissions with the influenza confirmed by the RT-PCR method between 2009 and 2011. The risk of hospital admission and the population attribuible fraction were calculated using the BMI or the CUN-BAE for each adiposity category in a conditional logical regression analysis adjusted for confounding variables. The analyzes were estimated in the total sample, in unvaccinated people, and those less than 65 years-old. A total of 472 hospitalised cases and 493 controls were included in the study. Compared to normal weight, the aOR of influenza hospital admissions increases with each level of BMI (aOR=1.26; 2.06 and 11.64) and CUN-BAE (aOR=2.78; 4.29; 5.43 and 15.18). The population attributable fraction of influenza admissions using CUN-BAE is 3 times higher than that estimated with BMI (0,72 vs. 0,27), with the differences found being similar the non-vaccinated and under 65 year-olds. The BMI could be underestimating the burden of disease attributable to obesity in individuals hospitalised with influenza. There needs to be an appropriate assessment of the impact of obesity and vaccine recommendation criteria. Copyright © 2017 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

    The contribution of air pollution on hospital admissions due to respiratory and heart diseases is a major issue in the health-environmental perspective. In the present study, an attempt was made to run down the relationships between air pollution levels and meteorological indexes, and corresponding hospital admissions in Athens, Greece. The available data referred to a period of eight years (1992-2000) including the daily number of hospital admissions due to respiratory and heart diseases, hourly mean concentrations of CO, NO 2, SO 2, O 3 and particulates in several monitoring stations, as well as, meteorological data (temperature, relative humidity, wind speed/direction). The relations among the above data were studied through widely used statistical techniques (multivariate stepwise analyses) and Artificial Neural Networks (ANNs). Both techniques revealed that elevated particulate concentrations are the dominant parameter related to hospital admissions (an increase of 10 μg m -3 leads to an increase of 10.2% in the number of admissions), followed by O 3 and the rest of the pollutants (CO, NO 2 and SO 2). Meteorological parameters also play a decisive role in the formation of air pollutant levels affecting public health. Consequently, increased/decreased daily hospital admissions are related to specific types of meteorological conditions that favor/do not favor the accumulation of pollutants in an urban complex. In general, the role of meteorological factors seems to be underestimated by stepwise analyses, while ANNs attribute to them a more important role. Comparison of the two models revealed that ANN adaptation in complicate environmental issues presents improved modeling results compared to a regression technique. Furthermore, the ANN technique provides a reliable model for the prediction of the daily hospital admissions based on air quality data and meteorological indices, undoubtedly useful for regulatory purposes.

    ABSTRACT Background: Cervix uteri cancer is the 4th most common cancer among women worldwide and the second most frequent cancer in women under 45 years old in Spain. We aimed to describe the burden of hospital admissions by malignant neoplasia (MN) and in situ carcinoma (ISC) of the cervix in Spain from 2003 to 2014, a 12-year period that included the first years after introduction of an HPV vaccination program. Methods: This epidemiological study reviewed data from the Ministry of Health National Surveillance System, which includes more than 98% of Spanish hospitals. Hospitalization rate, mortality rate, and case fatality rates were calculated per year and age group. Results: We found 74,933 hospitalizations due to MN and ISC of the cervix. The average age at hospitalization increased significantly during the study period. The average length of hospital stay decreased significantly (p<0.001), while hospitalization costs increased. The mean hospitalization rate was 27.532 cases per 100,000 women (95% CI: 27.335-27.729). This rate decreased significantly during the study period. The mean mortality rate was 1.418 deaths per 100,000 women (95% CI: 1.373-1.463) and the mean case-fatality rate was 5.150% (95% CI: 4.992-5.308). Conclusion: Our study showed a substantial decrease in the hospitalization burden due to cervical disease. This decrease could be attributable to different causes including cervical cancer prevention measures, and changes in disease management. Further research is needed to confirm the cause. This information could contribute to further evaluations of the impact and cost effectiveness analysis of HPV vaccination in Spain. PMID:29206085

    Ischaemic heart disease (IHD) is one of the leading causes of death worldwide. The effects of air pollution on IHD mortalities have been widely reported. Fewer studies focus on IHD morbidities and PM2.5, especially in Asia. To explore the associations between short-term exposure to air pollution and morbidities and mortalities from IHD, we conducted a time series study using a generalized additive model that regressed the daily numbers of IHD mortalities and hospital admissions on daily mean concentrations of the following air pollutants: nitrogen dioxide (NO2), particulate matter with an aerodynamic diameter less than 10 μm (PM10), particulate matter with an aerodynamic diameter less than 2.5 μm (PM2.5), ozone (O3), and sulfur dioxide (SO2). The relative risks (RR) of IHD deaths and hospital admissions per 10 μg/m3 increase in the concentration of each air pollutant were derived in single pollutant models. Multipollutant models were also constructed to estimate their RRs controlling for other pollutants. Significant RRs were observed for all five air pollutants, ranging from 1.008 to 1.032 per 10 μg/m3 increase in air pollutant concentrations for IHD mortality and from 1.006 to 1.021 per 10 μg/m3 for hospital admissions for IHD. In the multipollutant model, only NO2 remained significant for IHD mortality while SO2 and PM2.5 was significantly associated with hospital admissions. This study provides additional evidence that mortalities and hospital admissions for IHD are significantly associated with air pollution. However, we cannot attribute these health effects to a specific air pollutant, owing to high collinearity between some air pollutants.

    Somnambulism is a state of dissociated consciousness, in which the affected person is partially asleep and partially awake. There is pervasive public opinion that sleepwalkers are protected from hurting themselves. There have been few scientific reports of trauma associated with somnambulism and no published investigations on the epidemiology or trauma patterns associated with somnambulism. We included all emergency department (ED) admissions to University Hospital Inselspital, Berne, Switzerland, from January 1, 2000, until August 11, 2015, when the patient had suffered a trauma associated with somnambulism. Demographic data (age, gender, nationality) and medical data (mechanism of injury, final diagnosis, hospital admission, mortality and medication on admission) were included. Of 620,000 screened ED admissions, 11 were associated with trauma and sleepwalking. Two patients (18.2%) had a history of known non-rapid eye movement parasomnias. The leading cause of admission was falls. Four patients required hospital admission for orthopedic injuries needing further diagnostic testing and treatment (36.4%). These included two patients with multiple injuries (18.2%). None of the admitted patients died. Although sleepwalking seems benign in the majority of cases and most of the few injured patients did not require hospitalization, major injuries are possible. When patients present with falls of unknown origin, the possibility should be evaluated that they were caused by somnambulism.

    To develop pediatric direct admission guidelines and prioritize outcomes to evaluate the safety and effectiveness of hospital admission processes. We conducted deliberative discussions at 1 children's hospital and 2 community hospitals, engaging parents of hospitalized children and inpatient, outpatient, and emergency department physicians and nurses to identify shared and dissenting perspectives regarding direct admission processes and outcomes. Discussions were audio-recorded, professionally transcribed, and analyzed using a general inductive approach. We then convened a national panel to prioritize guideline components and outcome measures using a RAND/UCLA Modified Delphi approach. Forty-eight stakeholders participated in 6 deliberative discussions. Emergent themes related to effective multistakeholder communication, resources needed for high quality direct admissions, written direct admission guidelines, including criteria to identify children appropriate for and inappropriate for direct admission, and families' needs. Building on these themes, Delphi panelists endorsed 71 guideline components as both appropriate and necessary at children's hospitals and community hospitals and 13 outcomes to evaluate hospital admission systems. Guideline components include (1) pre-admission communication, (2) written guidelines, (3) hospital resources to optimize direct admission processes, (4) special considerations for pediatric populations that may be at particular risk of nosocomial infection and/or stress in emergency departments, (5) communication with families referred for direct admission, and (6) quality reviews to evaluate admission systems. These direct admission guidelines can be adapted by hospitals and health systems to inform hospital admission policies and protocols. Multistakeholder engagement in evaluation of hospital admission processes may improve transitions of care and health system integration. Copyright © 2018 Elsevier Inc. All rights reserved.

    2011-01-01

    Background Nursing home residents are prone to acute illness due to their high age, underlying illnesses and immobility. We examined the incidence of acute hospital admissions among nursing home residents versus the age-matched community dwelling population in a geographically defined area during a two years period. The hospital stays of the nursing home population are described according to diagnosis, length of stay and mortality. Similar studies have previously not been reported in Scandinavia. Methods The acute hospitalisations of the nursing home residents were identified through ambulance records. These were linked to hospital patient records for inclusion of demographics, diagnosis at discharge, length of stay and mortality. Incidence of hospitalisation was calculated based on patient-time at risk. Results The annual hospital admission incidence was 0.62 admissions per person-year among the nursing home residents and 0.26 among the community dwellers. In the nursing home population we found that dominant diagnoses were respiratory diseases, falls-related and circulatory diseases, accounting for 55% of the cases. The median length of stay was 3 days (interquartile range = 4). The in-hospital mortality rate was 16% and 30 day mortality after discharge 30%. Conclusion Acute hospital admission rate among nursing home residents was high in this Scandinavian setting. The pattern of diagnoses causing the admissions appears to be consistent with previous research. The in-hospital and 30 day mortality rates are high. PMID:21615911

    To understand the process that led Brazilian philanthropic general hospitals to implement psychiatric units and to describe the main characteristics and therapeutic approaches of these services. Ten institutions in three Brazilian states (Minas Gerais, São Paulo e Santa Catarina) were assessed in 2002. Forty-three semi-structured interviews were carried out with health professionals who worked at the hospitals to collect data on service implementation process, therapeutic approaches and current situation. The interviews were audio-recorded and their content was analyzed. There was no mental hospital in the cities where the institutions were located. In five hospitals, psychiatric patients were admitted to general medical wards because there was no psychiatric unit. The therapeutic approach in six hospitals was based on psychopharmacological treatment. Due to lack of resources and more appropriate therapeutic planning, the admission of patients presenting psychomotor agitation increases resistance against psychiatric patients in general hospitals. Financial constraints regarding laboratory testing is still a challenge. There is no exchange between local authorities and hospital administrators of these institutions that are compelled to exceed the allowed number of admissions to meet the demand of neighboring cities. The need for mental health care to local populations combined with individual requests of local authorities and psychiatrists made possible the implementation of psychiatric units in these localities. In spite of the efforts and flexibility of health professional working in these institutions, there are some obstacles to be overcome: resistance of hospital community against psychiatric admissions, financial constraints, limited professional training in mental health and the lack of a therapeutic approach that goes beyond psychopharmacological treatment alone.

    To develop and implement locally tailored pediatric admission guidelines for use in a pediatric emergency department and evaluate the appropriateness of admissions based on these guidelines. Our Study was based on the development of admission guidelines by senior physicians, using the Delphi Consensus Process, for use in the Pediatric Emergency Department (PED) at Soroka University Medical Center (Soroka). We evaluated the appropriateness of admissions to the pediatric departments of Soroka on 33 randomly selected days in 1999 and 2000 prior to guideline implementation and 30 randomly selected days in 2001, after guideline implementation. A total of 1037 files were evaluated. A rate of 12.4% inappropriate admissions to the pediatric departments was found based on locally tailored admission guidelines. There was no change in the rate of inappropriate admissions after implementation of admission guidelines in PED. Inappropriate admissions were associated with age above 3 years, hospital stay of two days or less and the season. The main reasons for evaluating an admission as inappropriate were that the admission did not comply with the guidelines and that the case could be managed in an ambulatory setting. There were distinctive differences in the characteristics of the Bedouin and Jewish populations admitted to the pediatric departments, although no difference was found in the rate of inappropriate admissions between these populations. Patient management in Soroka PED is tailored to the conditions of this medical center and to the characteristics of the population it serves. The admission guidelines developed reflect these special conditions. Lack of change in the rate of inappropriate admissions following implementation of the guidelines indicates that the guidelines reflect the physicians' approach to patient management that existed in Soroka PED prior to guideline implementation. Hospital admission guidelines have a role in the health management system; however

  11. Increasing malaria hospital admissions in Uganda between 1999 and 2009

    2011-01-01

    Background Some areas of Africa are witnessing a malaria transition, in part due to escalated international donor support and intervention coverage. Areas where declining malaria rates have been observed are largely characterized by relatively low baseline transmission intensity and rapid scaling of interventions. Less well described are changing patterns of malaria burden in areas of high parasite transmission and slower increases in control and treatment access. Methods Uganda is a country predominantly characterized by intense, perennial malaria transmission. Monthly pediatric admission data from five Ugandan hospitals and their catchments have been assembled retrospectively across 11 years from January 1999 to December 2009. Malaria admission rates adjusted for changes in population density within defined catchment areas were computed across three time periods that correspond to periods where intervention coverage data exist and different treatment and prevention policies were operational. Time series models were developed adjusting for variations in rainfall and hospital use to examine changes in malaria hospitalization over 132 months. The temporal changes in factors that might explain changes in disease incidence were qualitatively examined sequentially for each hospital setting and compared between hospital settings Results In four out of five sites there was a significant increase in malaria admission rates. Results from time series models indicate a significant month-to-month increase in the mean malaria admission rates at four hospitals (trend P < 0.001). At all hospitals malaria admissions had increased from 1999 by 47% to 350%. Observed changes in intervention coverage within the catchments of each hospital showed a change in insecticide-treated net coverage from <1% in 2000 to 33% by 2009 but accompanied by increases in access to nationally recommended drugs at only two of the five hospital areas studied. Conclusions The declining malaria disease

    Chronic obstructive pulmonary disease (COPD) is a major public health problem. The aim of this study was to ascertain the prevalence of COPD and whether such prevalence was positively or negatively associated with COPD admissions, using all the data of a regional health care system. We designed a descriptive cross-sectional study which included all subjects aged over 45 years, diagnosed with COPD in primary care in 2013. We also calculated the number of such patients who had a record of hospital admissions due to this disease. COPD prevalence and incidence of admissions were calculated. Poisson regression models were then used to analyse the association between cases with diagnosis of COPD and admissions due to COPD, by sex, adjusting for socio-demographic variables and distance to hospital. Sensitivity subanalyses were performed by reference to the respective municipal rurality indices. Median municipal prevalence of COPD was 5.29% in men and 2.19% in women. Among patients with COPD, 28.22% of men and 16.00% of women had at least one hospital admission. The relative risk of admission per unit of the standardised prevalence ratio was 0.37 (95% CI 0.34-0.41) for men and 0.39 (95% CI 0.34-0.45) for women. There is a significant negative association between COPD prevalence and hospital admissions due to this disease. The proportion of admissions is lower in municipalities lying furthest from hospitals. There is considerable municipal variability in terms of COPD prevalence and proportion of admissions. In-depth attention should be given to disease-management training programmes.

    Arid areas in the Arabian Peninsula are one of the largest sources of global dust, yet there is no data on the impact of this on human health. This study aimed to investigate the impact of dust storms on hospital admissions due to asthma and all respiratory diseases over a period of 5 years in Kuwait. A population-based retrospective time series study of daily emergency asthma admissions and admissions due to respiratory causes in public hospitals in Kuwait was analyzed in relation to dust storm events. Dust storm days were defined as the mean daily PM(10)>200 μg/m(3) based on measurements obtained from all six monitoring sites in the country. During the five-year study period, 569 (33.6%) days had dust storm events and they were significantly associated with an increased risk of same-day asthma and respiratory admission, adjusted relative risk of 1.07 (95% CI: 1.02-1.12) and 1.06 (95% CI: 1.04-1.08), respectively. This was particularly evident among children. Dust storms have a significant impact on respiratory and asthma admissions. Evidence is more convincing and robust compared to that from other geographical settings which highlights the importance of public health measures to protect people's health during dust storms and reduce the burden on health services due to dust events.

    Physicians often accuse their peers of being "black clouds" if they repeatedly have more than the average number of hospital admissions while on call. Our purpose was to determine whether the black-cloud phenomenon is real or explainable by random variation. We analyzed hospital admissions to the University of Iowa family medicine service from July 1, 2010 to June 30, 2015. Analyses were stratified by peer group (eg, night shift attending physicians, day shift senior residents). We analyzed admission numbers to find evidence of black-cloud physicians (those with significantly more admissions than their peers) and white-cloud physicians (those with significantly fewer admissions). The statistical significance of whether there were actual differences across physicians was tested with mixed-effects negative binomial regression. The 5-year study included 96 physicians and 6,194 admissions. The number of daytime admissions ranged from 0 to 10 (mean 2.17, SD 1.63). Night admissions ranged from 0 to 11 (mean 1.23, SD 1.22). Admissions increased from 1,016 in the first year to 1,523 in the fifth year. We found 18 white-cloud and 16 black-cloud physicians in simple regression models that did not control for this upward trend. After including study year and other potential confounding variables in the regression models, there were no significant associations between physicians and admission numbers and therefore no true black or white clouds. In this study, apparent black-cloud and white-cloud physicians could be explained by random variation in hospital admissions. However, this randomness incorporated a wide range in workload among physicians, with potential impact on resident education at the low end and patient safety at the high end.

    Asthma prevalence has been increasing consistently since 1995 in California. Recent studies have found that consuming soda and sugar-containing drinks may pose a risk for asthma. Research that examines the relationship between soda intake and asthma among adult asthmatics is limited. This study investigated the relationship between sugar-sweetened soda consumption and asthma hospitalization among adult asthmatics in California. This cross-sectional study was based on the 2011-2012 California Health Interview Survey (CHIS) data and included 3,784 adults who were diagnosed with asthma by a doctor and who currently reported either that they still had asthma, or that they had suffered from an asthma attack in the last 12 months. The analysis was survey weighted. The exposure variable was soda intake measured as the number of times soda was consumed in the last week. The health outcome measure was overnight hospital admission due to asthma. Logistic regression was used to examine the association between soda consumption and overnight hospital admission after adjusting for age, education, sex, race/ethnicity, weight status, smoking status, and self-rated health. Adults with asthma who drank soda three or more times per week reported higher odds of overnight hospitalization (adjusted odds ratio = 2.77, 95% CI: 1.51-5.10, p = 0.001). Our findings suggest that efforts designed to limit soda consumption would benefit asthma suffers by reducing hospital admissions. This, however, needs further research to confirm a direct causal association.

    The Great East Japan Earthquake and subsequent tsunami and nuclear disaster on 11 March 2011 had a short-term influence on the increase in emergency department visits and hospital admissions due to various diseases. However, it remains unclear whether the earthquake and tsunami disaster affected the long-term health conditions of people in the affected areas. Using a national inpatient database in Japan, we investigated people's ambulatory care sensitive conditions (ACSCs), which are defined as conditions for which effective management and treatment should prevent admission to a hospital. We compared the number of admissions for ACSCs before-quake (July 2010 to February 2011) with after-quake (July 2012 to February 2013) periods in the disaster area compared with other areas using a difference-in-differences design. Linear regression models with the interaction between periods and areas were used to estimate the impact of the earthquake on admissions for ACSCs. No significant difference in difference was seen in preventable ACSCs (where immunisation and other interventions can prevent illness) or chronic ACSCs (where effective care can prevent flare-ups), while acute ACSCs (where early intervention can prevent more serious progression) increased significantly (3.3 admissions per 100 000 population; 95% CI 0.4 to 6.3; p=0.028). Preventable and chronic ACSCs may have increased just after the earthquake and then immediately decreased. However, avoidable admissions due to acute ACSCs remained high in the long term after the earthquake and tsunami disaster. Published by the BMJ Publishing Group Limited.

    To determine the early predictors of respiratory hospital admissions in young people with cerebral palsy (CP). A 3-year prospective cohort study using linked data. Children and young people with CP, aged 1 to 26 years. Self-reported and carer-reported respiratory symptoms were linked to respiratory hospital admissions (as defined by the International Statistical Classification of Diseases and Related Health Problems 10th Revision codes) during the following 3 years. 482 participants (including 289 males) were recruited. They were aged 1 to 26 years (mean 10 years, 10 months; SD 5 years, 11 months) at the commencement of the study, and represented all Gross Motor Function Classification Scale (GMFCS) levels. During the 3-year period, 55 (11.4%) participants had a total of 186 respiratory hospital admissions, and spent a total of 1475 days in hospital. Statistically significant risk factors for subsequent respiratory hospital admissions over 3 years in univariate analyses were GMFCS level V, at least one respiratory hospital admission in the year preceding the survey, oropharyngeal dysphagia, seizures, frequent respiratory symptoms, gastro-oesophageal reflux disease, at least two courses of antibiotics in the year preceding the survey, mealtime respiratory symptoms and nightly snoring. Most risk factors for respiratory hospital admissions are potentially modifiable. Early identification of oropharyngeal dysphagia and the management of seizures may help prevent serious respiratory illness. One respiratory hospital admission should trigger further evaluation and management to prevent subsequent respiratory illness. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Background: Changing epidemiologic profile with increase in cardiovascular risk factors is well documented in literature. Our study sought to see how this is reflected in cardiovascular admissions into medical wards of a Nigerian and an Israeli hospital. Objective: To compare the range and pattern of cardiovascular admissions encountered in a Nigerian hospital and an Israel hospital. Methods: This was a retrospective study of admission records of patients admitted into both Federal Medical Centre (FMC), Umuahia, Abia State, Nigeria, and Sheba Medical Centre, Israel. Results: Ischemic heart disease (IHD) was the most prevalent among the Israeli hospital's admissions but ranks very low as an indication for admission in Nigeria. The most common causes of admission in Nigeria were hypertension and heart failure (HF). The spectrum of cardiovascular diseases (CVDs) was very limited in the Nigerian hospital, indicating disparity in diagnostic capacity. Conclusion: There were more patients with CVD as a cause of medical admission in the Israel hospital as compared to the Nigerian hospital. Hypertension and HF were prevalent indications for CVD in FMC, Umuahia, Nigeria, while hypertension and IHD were the prevalent indications for admission in Sheba Medical Centre, Israel. Future studies are needed to monitor spectrum and frequency of cardiovascular admissions in view of evolving epidemiological transition in developing countries. PMID:28469120

    Fall-related injuries, hospitalizations, and mortality among older persons represent a major public health problem. Owing to aging societies worldwide, a major impact on fall-related health care demand can be expected. We determined time trends in numbers and incidence of fall-related hospital admissions and in admission duration in older adults. Secular trend analysis of fall-related hospital admissions in the older Dutch population from 1981 through 2008, using the National Hospital Discharge Registry. All fall-related hospital admissions in persons 65 years or older were extracted from this database. Outcome measures were the numbers, and the age-specific and age-adjusted incidence rates (per 10,000 persons) of fall-related hospital admissions in each year of the study. From 1981 through 2008, fall-related hospital admissions increased by 137%. The annual age-adjusted incidence growth was 1.3% for men vs 0.7% for women (P < .001). The overall incidence rate increased from 87.7 to 141.2 per 10,000 persons (an increase of 61%). Age-specific incidence increased in all age groups, in both men and women, especially in the oldest old (>75 years). Although the incidence of fall-related hospital admissions increased, the total number of fall-related hospital days was reduced by 20% owing to a reduction in admission duration. In the Netherlands, numbers of fall-related hospital admissions among older persons increased drastically from 1981 through 2008. The increasing fall-related health care demand has been compensated for by a reduced admission duration. These figures demonstrate the need for implementation of falls prevention programs to control for increases of fall-related health care consumption.

    There is concern that existing models of acute hospital care will become unworkable as the health service admits an increasing number of frail older people with complex health needs, and that there is inadequate evidence to guide the planning of acute hospital level services. We aim to evaluate whether geriatrician-led admission avoidance to hospital at home is an effective alternative to hospital admission. We are conducting a multi-site randomised open trial of geriatrician-led admission avoidance hospital at home, compared with admission to hospital. We are recruiting older people with markers of frailty or prior dependence who have been referred to admission avoidance hospital at home for an acute medical event. This includes patients presenting with delirium, functional decline, dependence, falls, immobility or a background of dementia presenting with physical disease. Participants are randomised using a computerised random number generator to geriatrician-led admission avoidance hospital at home or a control group of inpatient admission in a 2:1 ratio in favour of the intervention. The primary endpoint 'living at home' (the inverse of death or living in a residential care setting) is measured at 6 months follow-up, and we also collect data on this outcome at 12 months. Secondary outcomes include the incidence of delirium, mortality, new long-term residential care, cognitive impairment, activities of daily living, quality of life and quality-adjusted survival, length of stay, readmission or transfer to hospital. We will conduct a parallel economic evaluation, and a process evaluation that includes an interview study to explore the experiences of patients and carers. Health systems around the world are examining how to provide acute hospital-level care to older adults in greater numbers with a fixed or shrinking hospital resource. This trial is the first large multi-site randomised trial of geriatrician-led admission avoidance hospital at home, and will

    concern over the sustainability of the National Health Service (NHS) is often focussed on rising numbers of hospital admissions, particularly among older people. Hospital admissions are enumerated routinely by the Hospital Episode Statistics (HES) Service, but published data do not allow individual-level service use to be explored. This study linked information on Hertfordshire Cohort Study (HCS) participants with HES inpatient data, with the objective of describing patterns and predictors of admissions among individuals. 2,997 community-dwelling men and women aged 59-73 years completed a baseline HCS assessment between 1998 and 2004; HES and mortality data to 31 March 2010 were linked with the HCS database. This paper describes patterns of hospital use among the cohort at both the admission and individual person level. the cohort experienced 8,741 admissions; rates were 391 per 1,000 person-years among men (95% CI: 380, 402) and 327 among women (95% CI: 316, 338), P < 0.0001 for gender difference. A total of 1,187 men (75%) and 981 women (69%) were admitted to hospital at least once; among these, median numbers of admissions were 3 in men (inter-quartile range, (IQR): 1, 6) and 2 in women (IQR: 1, 5). Forty-eight percent of those ever admitted had experienced an emergency admission and 70% had been admitted overnight. It is possible to link routinely collected HES data with detailed information from a cohort study. Hospital admission is common among community-dwelling 'young-old' men and women. These linked datasets will facilitate research into lifecourse determinants of hospital admission and inform strategies to manage demand on the NHS. © The Author 2013.

    Bordetella pertussis (whooping cough) is a worldwide public health problem. It is estimated that there are about 20 to 40 million cases with 200,000-400,000 deaths and is increasing in infants and adults. An observational, retrospective study was made. We reviewed the epidemiologic surveillance notification forms from 2001 to 2008 period at the Epidemiology Department of Hospital Del Niño, a tertiary paediatric reference centre in Panama City. All pertussis (whooping cough) cases confirmed by PCR and cultures were selected. From a total of 759 notifications of suspected whooping cough cases, 180 confirmed cases using PCR and culture were analyzed for this study. The admission rate in all ages was 14.4/10,000 admissions, predominantly in < or =3 months with 42.76/10,000 admissions and which accounted for 75% of the cases. Cough was the most important symptom (91%). Cyanosis, leucocytosis and lymphocytosis were the most characteristic clinical findings when comparing positive pertussis with negative. More than two thirds of the subjects less than 3 months of age had not been vaccinated at the time of admission. The death rate was 8.3%, more than half of them in subjects less than 1 month of age. Whooping cough is an important public health problem. Post-partum vaccination could be a strategy to reduce morbidity and mortality in infants less than 3 months of age. 2009 Asociación Española de Pediatría. Published by Elsevier Espana.

    In Italy a specific surveillance system for zoster does not exist, and thus updated and complete epidemiological data are lacking. The objective of this study was to retrospectively review the national hospital discharge forms database for the period 1999–2005 using the code ICD9-CM053. In the period 1999–2005, 35,328 hospital admissions have been registered with annual means of 4,503 hospitalizations and 543 day-hospital admissions. The great part of hospitalizations (61.9%) involved subjects older than 65 years; the mean duration of stay was 8 days. These data, even if restricted to hospitalizations registered at national level, confirm the epidemiological impact of shingles and of its complications. PMID:19826547

    Some effects of environmental pollution on human health are known, especially those affecting the respiratory and cardiovascular systems. The current study aimed to estimate these effects on the production of hospital admissions for stroke. This was an ecological study using hospital admissions data in São José dos Campos, São Paulo State, Brazil, with diagnosis of stroke, from January 1, 2007, to April 30, 2008. The target pollutants were particulate matter, sulfur dioxide, and ozone. Use of a Poisson linear regression model showed that same-day exposure to particulate matter was associated with hospitalization for stroke (RR = 1.013; 95%CI: 1.001-1.025). An increase of 10 µg/m(3) in this pollutant increased the risk of hospitalization by 12% (RR = 1.137; 95%CI: 1.014-1.276). In the multi-pollutant model, it was thus possible to identify particulate matter as associated with hospitalization for stroke in a medium-sized city like São José dos Campos.

    The city of Ostrava and its surroundings belong to the most long-therm polluted areas in the Czech Republic and Europe. For identification of health risk, the World Health Organization recommends a theoretical estimation of increased short-term PM 10 concentrations effect on hospital admissions for cardiac complaints based on a 0.6% increase per 10 µg.m -3 PM 10 and 1.14% increase for respiratory causes. The goal of the present study is to verify the percentage increase of morbidity due to cardiovascular and respiratory causes, as per WHO recommendations for health risk assessment, in the population of Ostrava. The input data include data on PM 10 air pollution, meteorological data, the absolute number of hospital admissions for acute cardiovascular and respiratory diseases in the period 2010-2012. To examine the association between air pollution and health outcomes the time series Poisson regression adjusted for covariates was used. A significant relationship was found between the cardiovascular hospital admissions (percentage increase of 1.24% per 10 µg.m -3 ) and values of PM 10 less than 150 µg.m -3 in the basic model, although after adjustment for other factors, this relationship was no longer significant. A significant relationship was also observed for respiratory causes of hospital admissions in the basic model. Contrary to cardiovascular hospitalization, the relationship between respiratory hospital admissions and PM 10 values below 150 µg.m -3 (percentage increase of 1.52%) remained statistically significant after adjustment for other factors. The observed significant relationship between hospital admissions for respiratory causes was consistent with the results of large European and American studies.

    Data on the health impacts of heatwaves in infants are limited, and this study aimed to examine how heatwaves affect hospital admissions in infants. A quasi-Poisson generalized additive model was used to assess the effects of heatwaves on hospital admissions in infants from 1st January 2005 to 31st December 2015 in Brisbane, Australia, using a series of heatwave definitions after controlling for possible confounders. A case-only analysis was conducted to examine the possible modification effects of personal and community characteristics on the heatwaves effects on infants' hospital admissions. There was no significant increase in infants' hospital admissions when heatwave intensity was defined as mean temperature ≥90 th percentile or ≥95th percentile of the mean temperature across the study period. When heatwave intensity increased to ≥97th percentile, infants' hospital admissions increased significantly (RR: 1.05, 95% CI: 1.01, 1.10), and this increase raised with the increase of heatwave duration. No modification effect of gender, indigenous status, or Socio-Economic Indexes for Areas (SEIFA) level on heatwave effect was observed. Infants in Brisbane were sensitive to intense heatwaves, and future heat early warning system based on a local evidence-based heatwave definition is needed to protect infants from heatwave impacts. Community-based heatwave adaptation programs aiming at raising the awareness of the adverse health impacts of intense heatwaves among infants' caregivers may relieve the postnatal health care demand in infants.

    Studies in the USA and Canada have reported increasing or stable rates of hospital admissions for hypoglycaemia. Some data from small studies are available for other countries. We aimed to gather information about long-term trends in hospital admission for hypoglycaemia and subsequent outcomes in England to help widen understanding for the global burden of hospitalisation for hypoglycaemia. We collected data for all hospital admissions listing hypoglycaemia as primary reason of admission between Jan 1, 2005, and Dec 31, 2014, using the Hospital Episode Statistics database, which contains details of all admissions to English National Health Service (NHS) hospital trusts. We calculated trends in crude and adjusted (for age, sex, ethnic group, social deprivation, and Charlson comorbidity score) admissions for hypoglycaemia; in admissions for hypoglycaemia per total hospital admissions and per diabetes prevalence in England; and in length of stay, in-hospital mortality, and 1 month readmissions for hypoglycaemia. 79 172 people had 101 475 admissions for hypoglycaemia between 2005 and 2014, of which 72 568 (72%) occurred in people aged 60 years or older. 13 924 (18%) people had more than one admission for hypoglycaemia during the study period. The number of admissions increased steadily from 7868 in 2005, to 11 756 in 2010 (49% increase) and then remained more stable until 2014 (10 977; 39% increase from baseline, range across English regions 11-89%); the trend was similar after adjustment for risk factors, with a rate ratio of 1·53 (95% CI 1·29-1·81) for 2014 versus 2005. Admissions for hypoglycaemia per 100 000 total hospital admissions increased from 63·6 to 78·9 between 2005-06 and 2010-11 (24% increase), and then fell to 72·3 per 100 000 in 2013-14 (14% overall increase). Accounting for diabetes prevalence data, rates declined from 4·64 to 3·86 admissions per 1000 person-years with diabetes between 2010-11 and 2013-14. We were unable to

    We characterize hospital admissions among older adults for any cause in the 30 days after a significant natural disaster in the United States. The main outcome was all-cause hospital admissions in the 30 days after natural disaster. Separate analyses were conducted to examine all-cause hospital admissions excluding the 72 hours after the disaster, ICU admissions, all-cause inhospital mortality, and admissions by state. A self-controlled case series analysis using the 2011 Medicare Provider and Analysis Review was conducted to examine exposure to natural disaster by elderly adults located in zip codes affected by tornadoes during the 2011 southeastern superstorm. Spatial data of tornado events were obtained from the National Oceanic and Atmospheric Administration's Severe Report database, and zip code data were obtained from the US Census Bureau. All-cause hospital admissions increased by 4% for older adults in the 30 days after the April 27, 2011, tornadoes (incidence rate ratio 1.04; 95% confidence interval 1.01 to 1.07). When the first 3 days after the disaster that may have been attributed to immediate injuries were excluded, hospitalizations for any cause also remained higher than when compared with the other 11 months of the year (incidence rate ratio 1.04; 95% confidence interval 1.01 to 1.07). There was no increase in ICU admissions or inhospital mortality associated with the natural disaster. When data were examined by individual states, Alabama, which had the highest number of persons affected, had a 9% increase in both hospitalizations and ICU admissions. When all time-invariant characteristics were controlled for, this natural disaster was associated with a significant increase in all-cause hospitalizations. This analysis quantifies acute care use after disasters through examining all-cause hospitalizations and represents an important contribution to building models of resilience-the ability to recover from a disaster-and hospital surge capacity

    The objective of this study was to describe the occurrence of skin infection associated hospitalizations in children born in Western Australia (WA). We conducted a retrospective cohort study of all children born in WA between 1996 and 2012 (n = 469,589). Of these, 31,348 (6.7%) were Aboriginal and 240,237 (51.2%) were boys. We report the annual age-specific hospital admission rates by geographical location and diagnostic category. We applied log-linear regression modelling to analyse changes in temporal trends of hospitalizations. Hospitalization rates for skin infections in Aboriginal children (31.7/1000 child-years; 95% confidence interval [CI] 31.0-32.4) were 15.0 times higher (95% CI 14.5-15.5; P<0.001) than those of non-Aboriginal children (2.1/1000 child-years; 95% CI 2.0-2.1). Most admissions in Aboriginal children were due to abscess, cellulitis and scabies (84.3%), while impetigo and pyoderma were the predominant causes in non-Aboriginal children (97.7%). Admissions declined with age, with the highest rates for all skin infections observed in infants. Admissions increased with remoteness. Multiple admissions were more common in Aboriginal children. Excess admissions in Aboriginal children were observed during the wet season in the Kimberley and during summer in metropolitan areas. Our study findings show that skin infections are a significant cause of severe disease, requiring hospitalization in Western Australian children, with Aboriginal children at a particularly high risk. Improved community-level prevention of skin infections and the provision of effective primary care are crucial in reducing the burden of skin infection associated hospitalizations. The contribution of sociodemographic and environmental risk factors warrant further investigation.

    2013-01-01

    OBJECTIVE: To assess whether the implementation of English smoke-free legislation in July 2007 was associated with a reduction in hospital admissions for childhood asthma. METHODS: Interrupted time series study using Hospital Episodes Statistics data from April 2002 to November 2010. Sample consisted of all children (aged ≤14 years) having an emergency hospital admission with a principle diagnosis of asthma. RESULTS: Before the implementation of the legislation, the admission rate for childhood asthma was increasing by 2.2% per year (adjusted rate ratio 1.02; 95% confidence interval [CI]: 1.02–1.03). After implementation of the legislation, there was a significant immediate change in the admission rate of −8.9% (adjusted rate ratio 0.91; 95% CI: 0.89–0.93) and change in time trend of −3.4% per year (adjusted rate ratio 0.97; 95% CI: 0.96–0.98). This change was equivalent to 6802 fewer hospital admissions in the first 3 years after implementation. There were similar reductions in asthma admission rates among children from different age, gender, and socioeconomic status groups and among those residing in urban and rural locations. CONCLUSIONS: These findings confirm those from a small number of previous studies suggesting that the well-documented population health benefits of comprehensive smoke-free legislation appear to extend to reducing hospital admissions for childhood asthma.

    weekend days than weekdays (35.9 vs. 80.8). The mortality rate was significantly higher at weekends amongst direct admissions (risk-adjusted OR: 1.212) due to the proportionately greater reduction in admissions relative to deaths. Conclusions There are fewer deaths following hospital admission at weekends. Higher mortality rates at weekends are found only amongst the subset of patients who are admitted. The reduced availability of primary care services and the higher Accident and Emergency admission threshold at weekends mean fewer and sicker patients are admitted at weekends than during the week. Extending services in hospitals and in the community at weekends may increase the number of emergency admissions and therefore lower mortality, but may not reduce the absolute number of deaths.

    Objectives Alcohol is responsible for a proportion of emergency admissions to hospital, with acute alcohol intoxication and chronic alcohol dependency (CAD) implicated. This study aims to quantify the proportion of hospital admissions through our emergency department (ED) which were thought by the admitting doctor to be (largely or partially) a result of alcohol consumption. Setting ED of a UK tertiary referral hospital. Participants All ED admissions occurring over 14 weeks from 1 September to 8 December 2012. Data obtained for 5497 of 5746 admissions (95.67%). Primary outcome measures Proportion of emergency admissions related to alcohol as defined by the admitting ED clinician. Secondary outcome measures Proportion of emergency admissions due to alcohol diagnosed with acute alcohol intoxication or CAD according to ICD-10 criteria. Results 1152 (21.0%, 95% CI 19.9% to 22.0%) of emergency admissions were thought to be due to alcohol. 74.6% of patients admitted due to alcohol had CAD, and significantly greater than the 26.4% with ‘Severe’ or ‘Very Severe’ acute alcohol intoxication (p<0.001). Admissions due to alcohol differed to admissions not due to alcohol being on average younger (45 vs 56 years, p<0.001) more often male (73.4% vs 45.1% males, p<0.001) and more likely to have a diagnosis synonymous with alcohol or related to recreational drug use, pancreatitis, deliberate self-harm, head injury, gastritis, suicidal ideation, upper gastrointestinal bleeds or seizures (p<0.001). An increase in admissions due to alcohol on Saturdays reflects a surge in admissions with acute alcohol intoxication above the weekly average (p=0.003). Conclusions Alcohol was thought to be implicated in 21% of emergency admissions in this cohort. CAD is responsible for a significantly greater proportion of admissions due to alcohol than acute intoxication. Interventions designed to reduce alcohol-related admissions must incorporate measures to tackle CAD. PMID:27324707

    To examine the relationship between local macroeconomic indicators and physical abuse admission rates to pediatric hospitals over time. Retrospective study of children admitted to 38 hospitals in the Pediatric Hospital Information System database. Hospital data were linked to unemployment, mortgage delinquency, and foreclosure data for the associated metropolitan statistical areas. Primary outcomes were admission rates for (1) physical abuse in children <6 years old, (2) non-birth, non-motor vehicle crash-related traumatic brain injury (TBI) in infants <1 year old (which carry high risk for abuse), and (3) all-cause injuries. Poisson fixed-effects regression estimated trends in admission rates and associations between those rates and trends in unemployment, mortgage delinquency, and foreclosure. Between 2000 and 2009, rates of physical abuse and high-risk TBI admissions increased by 0.79% and 3.1% per year, respectively (P ≤ .02), whereas all-cause injury rates declined by 0.80% per year (P < .001). Abuse and high-risk TBI admission rates were associated with the current mortgage delinquency rate and with the change in delinquency and foreclosure rates from the previous year (P ≤ .03). Neither abuse nor high-risk TBI rates were associated with the current unemployment rate. The all-cause injury rate was negatively associated with unemployment, delinquency, and foreclosure rates (P ≤ .007). Multicenter hospital data show an increase in pediatric admissions for physical abuse and high-risk TBI during a time of declining all-cause injury rate. Abuse and high-risk TBI admission rates increased in relationship to local mortgage delinquency and foreclosure trends.

    To evaluate the rate of post-procedure emergency department (ED) visits and hospital admissions following outpatient non-vascular image-guided interventions performed under moderate sedation and to identify common and preventable causes of emergency department visits and hospital admissions. Institutional review board approval was acquired for this HIPAA-compliant retrospective study with waiver of informed consent. 1426 consecutive patients undergoing 1512 outpatient image-guided procedures under moderate sedation from November 2012 to August 2014 were included. The average patient age was 57.2 ± 15.2 years, and 602 (42%) patients were women. Major procedure categories included ultrasound-guided liver biopsies, ultrasound-guided kidney biopsies, and CT-guided lung biopsies/fiducial placement. Procedure details and medical follow-up within and after 30 days of the procedure were analyzed. A total of 168 (11.8%) patients were admitted to the hospital within 30 days of the procedure, with 29 of the admissions (17.3% of total admissions and 1.9% of total procedures) being procedure related. The most common procedure-related complication that required admission was hemorrhage (10/29, 34.5% of procedure-related admissions, 6.0% of total admissions, and 0.7% of total procedures), followed by pneumothorax (9/29, 31%, 5.4%, 0.6%), infection (4/29, 13.8%, 2.4%, 0.3%), and pain (3/29, 10.3%, 1.8%, 0.2%). Eighteen (62.1%) procedure-related admissions were immediately indicated. Thirty patients visited the ED and were subsequently discharged without admission with eight of the visits being procedure related (8/1512, 0.5%). All the procedure-related ED visits were due to pain. There were two deaths (2/1512, 0.1%) related to procedures, one from a thromboembolic event and another from post-biopsy hemorrhage. Outpatient non-vascular image-guided procedures result in a 30-day 1.9% hospital admission, 30-day 0.5% emergency room visit, and 30-day 0.1% mortality rate.

    Asthma is a chronic disease that can result in exacerbations leading to urgent care in emergency departments (EDs) and hospitals. We examined seasonal and temporal trends in pediatric asthma ED (1997-1999) and hospital (1986-1999) admission data so as to identify periods of increased risk of urgent care by age group, gender, and race. All pediatric ED and hospital admission data for Maryland residents occurring within the state of Maryland were evaluated. Distinct peaks in pediatric ED and hospital asthma admissions occurred each year during the winter-spring and autumn seasons. Although the number and timing of these peaks were consistent across age and racial groups, the magnitude of the peaks differed by age and race. The same number, timing, and relative magnitude of the major peaks in asthma admissions occurred statewide, implying that the variables affecting these seasonal patterns of acute asthma exacerbations occur statewide. Similar gross seasonal trends are observed worldwide. Although several environmental, infectious, and psychosocial factors have been linked with increases in asthma exacerbations among children, thus far they have not explained these seasonal patterns of admissions. The striking temporal patterns of pediatric asthma admissions within Maryland, as described here, provide valuable information in the search for causes.

    This study evaluated risk factors for intensive care unit (ICU) admission or death among people hospitalized with 2009 pandemic influenza A (pH1N1) virus infection. We based analyses on data collected in Washington State from April 27 to September 18, 2009, on deceased or hospitalized people with laboratory-confirmed pH1N1 infection reported by health-care providers and hospitals as part of enhanced public health surveillance. We used bivariate analyses and multivariable logistic regression to identify risk factors associated with ICU admission or death due to pH1N1. We identified 123 patients admitted to the hospital but not an ICU and 61 patients who were admitted to an ICU or died. Independent of high-risk medical conditions, both older age and delayed time to hospital admission were identified as risk factors for ICU admission or death due to pH1N1. Specifically, the odds of ICU admission or death were 4.44 times greater among adults aged 18-49 years (95% confidence interval [CI] 1.97, 10.02) and 5.93 times greater among adults aged 50-64 years (95% CI 2.24, 15.65) compared with pediatric patients < 18 years of age. Likewise, hospitalized cases admitted more than two days after illness onset had 2.17 times higher odds of ICU admission or death than those admitted within two days of illness onset (95% CI 1.10, 4.25). Although certain medical conditions clearly influence the need for hospitalization among people infected with pH1N1 virus, older age and delayed time to admission each played an independent role in the progression to ICU admission or death among hospitalized patients.

    Psychological distress and lack of family support may explain the mental health problems that are consistently found in young unaccompanied refugees in Western countries. Given the strong relationship between poor mental health and alcohol misuse, this study investigated hospital admissions due to alcohol related disorders among accompanied and unaccompanied young refugees who settled in Sweden as teenagers. The dataset used in this study was derived from a combination of different registers. Cox regression models were used to estimate the risks of hospital care due to alcohol related disorders in 15,834 accompanied and 4376 unaccompanied young refugees (2005-2012), aged 13 to 19 years old when settling in Sweden and 19 to 32 years old in December 2004. These young refugees were divided into regions with largely similar attitudes toward alcohol: the former Yugoslavian republics, Somalia, and the Middle East. The findings were compared with one million peers in the native Swedish population. Compared to native Swedes, hospital admissions due to alcohol related disorders were less common in young refugees, with a hazard ratio (HR) of 0.65 and 95% confidence interval (CI) between 0.56 and 0.77. These risks were particularly lower among young female refugees. However, there were some differences across the refugee population. For example, the risks were higher in unaccompanied (male) refugees than accompanied ones (HR = 1.49, 95% CI = 1.00-2.19), also when adjusted for age, domicile and income. While the risks were lower in young refugees from Former Yugoslavia and the Middle East relative to native Swedes, independent of their length of residence in Sweden, refugees from Somalia who had lived in Sweden for more than ten years showed increased risks (HR = 2.54, 95% CI = 1.71-3.76), after adjustments of age and domicile. These risks decreased considerably when income was adjusted for. Young refugees have lower risks of alcohol disorders compared with native

    Identification of 'cut-points' or thresholds of climate factors would play a crucial role in alerting risks of climate change and providing guidance to policymakers. This study investigated a 'Climate Threshold' for emergency hospital admissions of chronic lower respiratory diseases by using a distributed lag non-linear model (DLNM). We analysed a unique longitudinal dataset (10 years, 2000-2009) on emergency hospital admissions, climate, and pollution factors for the Greater London. Our study extends existing work on this topic by considering non-linearity, lag effects between climate factors and disease exposure within the DLNM model considering B-spline as smoothing technique. The final model also considered natural cubic splines of time since exposure and 'day of the week' as confounding factors. The results of DLNM indicated a significant improvement in model fitting compared to a typical GLM model. The final model identified the thresholds of several climate factors including: high temperature (≥27°C), low relative humidity (≤ 40%), high Pm10 level (≥70-µg/m 3 ), low wind speed (≤ 2 knots) and high rainfall (≥30mm). Beyond the threshold values, a significantly higher number of emergency admissions due to lower respiratory problems would be expected within the following 2-3 days after the climate shift in the Greater London. The approach will be useful to initiate 'region and disease specific' climate mitigation plans. It will help identify spatial hot spots and the most sensitive areas and population due to climate change, and will eventually lead towards a diversified health warning system tailored to specific climate zones and populations.

    Tibet of China, with an average altitude of over 4000 m, has experienced noticeable changes in its climate over the last 50 years. The association between temperature and morbidity (most commonly represented by hospital admissions) has been documented mainly in developed countries. Little is known about patterns in China; nor have the health effects of temperature variations been closely studied in highland areas, worldwide. We investigated the temperature-morbidity association in Lhasa, the capital city of Tibet, using sex- and age-specific hospitalizations, excluding those due to external causes. A distributed lag non-linear model (DLNM) was applied to assess the nonlinear and delayed effects of temperature on morbidity (including total emergency room visits, total and cause-specific hospital admissions, sex- and age-specific non-external admissions). High temperatures are associated with increases in morbidity, to a greater extent than low temperatures. Lag effects of high and low temperatures were cause-specific. The relative risks (RR) of high temperature for total emergency room visits and non-external hospitalizations were 1.162 (95% CI: 1.002-1.349) and 1.161 (95% CI: 1.007-1.339) respectively, for lag 0-14 days. The strongest cumulative effect of heat for lag 0-27 days was on admissions for infectious diseases (RR: 2.067, 95% CI: 1.026-4.027). Acute heat effects at lag 0 were related with increases of renal (RR: 1.478, 95% CI: 1.005-2.174) and respiratory diseases (RR: 1.119, 95% CI: 1.010-1.240), whereas immediate cold effects increased admission for digestive diseases (RR: 1.132, 95% CI: 1.002-1.282). Those ≥65 years of age and males were more vulnerable to high temperatures. We provide a first look at the temperature-morbidity relationship in Tibet. Exposure to both hot and cold temperatures resulted in increased admissions to hospital, but the immediate causes varied. We suggest that initiatives should be taken to reduce the adverse effects of

    People with intellectual developmental disorders (IDD) have worse health statuses in comparison with general population. The objective of this paper is to compare access and hospital morbimortality in people with IDD and general population. We conducted a retrospective cross-sectional analytical study and analyzed data on admissions and discharges between IDD patients and the rest of them, in Ciudad Real, España. Out of 51 325 hospital admissions, 441 (0.9%) belonged to the group of persons with IDD. The IDD group had fewer programmed hospitalization than the general population and fewer surgical interventions. They presented more admissions for mental disorders and respiratory system diseases. The data presented confirm TDI population have different patterns of disease. Furthermore, this study reveal potential difficulties in access to health care in this population.

    The evolution of the legislation governing compulsory admission to hospital in Tunisia is interesting for two reasons. The country's 2011 revolution notably brought about major changes to the legislative framework, from constitutional through to ordinary laws. At the same time, the current trend for globalisation is also affecting legislation: international laws, treaties and UN charters are imposed on the laws of individual countries. This article looks at how Tunisian law governing compulsory admission to hospital has had to evolve. Copyright © 2015. Published by Elsevier Masson SAS.

    The goal was to compare epidemiology of hospital admissions for traumatic brain injury (TBI) in Austrian residents vs. visitors to Austria. Data on all hospital admissions due to TBI (ICD-10 codes S06.0-S06.9; years 2009-2011) was provided by the Austrian Statistical Office. Data on Austrian population and on tourism (visitor numbers, nights spent) was retrieved from www.statistik.at . Age, sex, mechanism of injury, season and mortality was analysed for Austrian residents vs. visitors. Visitors contributed 3.9% to the total population and 9.2% of all TBI cases. Incidence of hospital admissions was 292/100,000/year in Austrian residents and was 727/100,000/year in visitors. Male:female ratio was 1.39:1 in Austrian residents and 1.55:1 in visitors. Austrian cases were older than visitors' cases (mean age 41 vs. 28 years). Austrian cases were distributed evenly over the seasons, while 75% of the visitors' cases happened during winter and spring. The most frequently observed causes of TBI in Austrian residents were private accidents, while sports caused almost half of the visitors' cases. Hospital mortality was lower in visitors than in Austrian residents (0.8 vs. 2.1%). Sports-related TBI of visitors causes a significant workload for Austrian hospitals. Better prevention is warranted.

    The appropriate use of health care is an important issue in developed countries. The purpose of this study was to ascertain the extent of potentially inappropriate hospital admissions and their individual, clinical and hospital-related determinants. Medical records were analyzed for the year 2014 held by the Local Heath Unit n. 13 in the Veneto Region of north-east Italy (19,000 records). The outcomes calculated were: admissions for conditions amenable to day hospital care; brief medical admissions; outlier lengths of stay for elderly patients' medical admissions; and medical admissions to surgical wards. Univariate analyses and logistic regression models were used to test associations with demographic, clinical and hospital ward covariates, including organizational indicators. Inappropriate reliance on acute care beds ranged from 6% to 28%, depending on the type of quality indicator analyzed. Some individual features, and wards' specific characteristics were associated with at least one of the phenomena of inappropriate hospital resource usage. In particular, male gender, younger age and transferals seemed to affect inappropriate admissions to surgical wards. Potentially avoidable admissions featuring inpatients amenable to day hospital care were associated with subjects with fewer comorbidities and lower case-mix wards, while inappropriately short medical stays were influenced by patients' higher functional status and local residency and by lower bed occupancy rates. In conclusion, inappropriately long hospital stays for elderly cases were associated with patients with multiple pathologies in wards with a low bed-occupancy. Education level and citizenship did not seem to influence inappropriate admissions. Some individual, clinical ad structural characteristics of patients and wards emerging from administrative records could be associated with inappropriate reliance on acute hospital beds. Analyzing the indicators considered in this study could generate

    Hospital crowding is a public health problem that may impact on the quality of medical treatment and increase the risk of developing traumatic stress, e.g., after myocardial infarction (MI). This study examines whether subjective appraisal of crowding at hospital admission due to MI is associated with acute stress disorder (ASD) symptoms. We investigated 102 consecutive patients with acute MI within 48h after having reached stable circulatory conditions. The appraisal of crowding was measured by the retrospective assessment of the perception of a hectic hospital environment at admission. Furthermore, patients completed the Acute Stress Disorder Scale to rate the psychological stress reaction. The perception of a hectic hospital environment was associated with the development of ASD symptoms (r=0.254, P=.013) independently of demographic, peritraumatic and medical factors. Post hoc analysis revealed associations with dissociative (r=0.211, P=.041), reexperiencing (r=0.184, P=.074) and arousal (r=0.179, P=.083) symptoms. The findings suggest that, besides objective circumstances, the way hospital admission due to MI is perceived by the patient may influence the development of MI-triggered ASD symptoms. The psychological and physiological long-term outcomes of the perception of a hectic hospital environment and the role of preventive interventions need further examination.

    To assess the burden of infectious and parasitic diseases on hospital services at District Civil Hospital (DCH) Belgaum, a retrospective study was carried out using discharge records concerning 8506 inpatients due to infectious and parasitic diseases among 95,655 patients admitted for all causes during the reference period 2000-2003. Out of the 21 causes of infectious and parasitic diseases, only 5 contributed maximally towards hospital admission. The most frequent cause was intestinal infections (44.0%) followed by tuberculosis (35.4%). 57.5% of these admissions were from the productive age group of 20-54 years. Tuberculosis is the most important disease in terms of hospital bed days (59.7%). Tuberculosis and intestinal infectious diseases represent more than three-fourth of the overall burden in terms of hospital bed days.

    Medical education programs in general, and rural residency programs in particular, can be beneficial for rural hospitals. This study of 1,792 non-metropolitan statistical area, acute general hospitals with fewer than 200 beds from 1993 to 1996 was designed to help rural hospitals and communities to quantify the likely effects of rural residency programs on hospital admissions. Data came from the hospital Prospective Payment System minimum data set. The results show that additional residents at rural hospitals with fewer than 200 beds generally result in an increase of approximately 100 to 200 admissions per resident--more for smaller hospitals and fewer for larger hospitals. Because increased admissions generally improve the financial health and continued operation of rural hospitals, this study confirms the importance of education-based strategies in ensuring access to care in rural communities.

    To describe direct medical costs of influenza in hospitalized elderly, with and without intensive care unit (ICU) admission, during the 2014-2015 season in Hong Kong. A retrospective study was conducted in 110 inpatients aged ≥65 years with laboratory-confirmed influenza treated by antiviral therapy during season 2014-2015 in a tertiary hospital. Resource utilization of influenza-related diagnostic and laboratory tests, medications for influenza treatment, usage of general medical ward and ICU during the influenza-related length of hospital stay (IR-LOS) were collected. There were 18 (16.4%) and 92 (83.4%) cases with and without ICU admission, respectively. The difference in influenza-related mortality rates between patients with (11.1%) and without ICU admission (2.2%) was not statistically significant (P=0.064). Patients with ICU admission reported longer IR-LOS (12.7 ±6.0 days versus 5.5 ±2.7 days; P<0.001) and higher direct costs (36,588 USD ±21,482 versus 5,773 USD ±2,017; P<0.001; 1 USD=7.8 HKD). Male gender (OR=14.50; 95% CI 1.68, 125.07) and respiratory complications (OR=9.61; 95% CI 1.90, 48.50) were positive predictors of ICU admission. Age ≥70 years (OR=0.09; 95% CI 0.02, 0.46) and antiviral therapy initiation within 7 days (OR=0.05; 95% CI 0.003, 0.79) were negative predictors of ICU admission. Influenza B was a positive predictor of high-cost hospitalization in non-ICU survivors (OR=7.33; 95% CI 1.24, 43.29). No predictor of mortality was identified. Hospitalization cost in elderly for seasonal influenza was substantial in Hong Kong. The cost in patients with ICU admission was significantly higher than those without ICU care. Respiratory complications and male gender predicted ICU admission. Influenza B infection predicted high-cost hospitalization in non-ICU survivors.

    Preterm patent ductus arteriosus (PDA) requires neonatal intensive care. The relationship between hospital volume and mortality of PDA remains poorly understood. This was a retrospective observational study, using a national inpatient database in Japan. We identified patients who were diagnosed with PDA; exclusion criteria were as follows: (i) other cardiac complications; (ii) mild PDA treated without oral/i.v. indomethacin, surgery, or catheter intervention; (iii) age >1 year at admission; (iv) gestational age ≥32 weeks; (v) death within 3 days of admission; and (vi) transferal to other hospitals. Information was collected using the Japanese Diagnosis Procedure Combination database from July 2010 to March 2013. Hospital volume was defined as the average annual number of neonates with gestational age <32 weeks at each hospital. The outcome measure was in-hospital mortality. A total of 2437 eligible patients treated at 199 hospitals were included. Low, medium, and high volume were defined as average annual number of preterm infants <34, 34-65, and >65, respectively. There were no significant differences in in-hospital mortality according to hospital volume. In-hospital mortality was identical in patients who received indomethacin alone, surgical or catheter intervention, or both after adjustment for patient background. There was no significant relationship between hospital volume and in-hospital mortality due to preterm PDA. Centralization of patients with this condition may not be necessary. © 2016 Japan Pediatric Society.

    Objectives This paper aims to systematically review observational studies that have analysed whether depressive symptoms in the community are associated with higher general hospital admissions, longer hospital stays and increased risk of re-admission. Methods We identified prospective studies that looked at depressive symptoms in the community as a risk factor for non-psychiatric general hospital admissions, length of stay or risk of re-admission. The search was carried out on MEDLINE, PsycINFO, Cochrane Library Database, and followed up with contact with authors and scanning of reference lists. Results Eleven studies fulfilled our inclusion and exclusion criteria, and all were deemed to be of moderate to high quality. Meta-analysis of seven studies with relevant data suggested that depressive symptoms may be a predictor of subsequent admission to a general hospital in unadjusted analyses (RR = 1.36, 95% CI: 1.28–1.44), but findings after adjustment for confounding variables were inconsistent. The narrative synthesis also reported depressive symptoms to be independently associated with longer length of stay, and higher re-admission risk. Conclusions Depressive symptoms are associated with a higher risk of hospitalisation, longer length of stay and a higher re-admission risk. Some of these associations may be mediated by other factors, and should be explored in more details. PMID:25466985

    The ageing British population is placing increased demands on the delivery of care in mainstream health-care institutions. While people are living longer, a significant percentage is also living with one or more long-term conditions. These issues, alongside continuing financial austerity measures, require a radical improvement in the care of patients away from hospitals. The Wyre Forest Clinical Commissioning Group introduced a virtual ward model for two main purposes: to save on spiralling costs of hospital admissions, and, secondly, to ensure the preferred wishes of most patients to be cared for and even die at home were achieved. This commentary describes how the virtual ward model was implemented and the impact of preventing unplanned emergency admissions to hospitals. The setting up of enhanced care services and virtual wards in one county is discussed, aiming to highlight success points and potential pitfalls to avoid. The results from the implementation of the virtual ward model show a significant reduction in emergency and avoidable patient admissions to hospital. The success of virtual wards is dependent on integrated working between different health-care disciplines.

    Frequent admitters to hospitals are high-cost patients who strain finite healthcare resources. However, the exact risk factors for frequent admissions, which can be used to guide risk stratification and design effective interventions locally, remain unknown. Our study aimed to identify the clinical and sociodemographic risk factors associated with frequent hospital admissions in Singapore. An observational study was conducted using retrospective 2014 data from the administrative database at Singapore General Hospital, Singapore. Variables were identified a priori and included patient demographics, comorbidities, prior healthcare utilisation, and clinical and laboratory variables during the index admission. Multivariate logistic regression analysis was used to identify independent risk factors for frequent admissions. A total of 16,306 unique patients were analysed and 1,640 (10.1%) patients were classified as frequent admitters. On multivariate logistic regression, 16 variables were independently associated with frequent hospital admissions, including age, cerebrovascular disease, history of malignancy, haemoglobin, serum creatinine, serum albumin, and number of specialist outpatient clinic visits, emergency department visits, admissions preceding index admission and medications dispensed at discharge. Patients staying in public rental housing had a 30% higher risk of being a frequent admitter after adjusting for demographics and clinical conditions. Our study, the first in our knowledge to examine the clinical risk factors for frequent admissions in Singapore, validated the use of public rental housing as a sensitive indicator of area-level socioeconomic status in Singapore. These risk factors can be used to identify high-risk patients in the hospital so that they can receive interventions that reduce readmission risk. Copyright: © Singapore Medical Association

    The relationships between the exposure of pollutants towards hospitalized admission and mortality have been identified in several studies on Asian cities such as Taipei, Bangkok and Tokyo. In Malaysia, evidence on the health risks associated with exposure to pollutants is limited. In this study, daily time-series data were analysed to estimate risks of cardiovascular and respiratory hospitalized admissions associated with particulate matter ≤ 10 μm (PM10), carbon monoxide (CO), nitrogen dioxide, sulphur dioxide, and ozone concentrations in Klang Valley during 2004-2009. Daily counts of hospital admissions for cardiovascular and respiratory outcomes were obtained from eleven hospitals while pollutants data were taken from several air quality monitoring stations located nearest to the hospitals. These data were fitted with Generalised Additive Poisson regression models. Additionally, temperature, humidity, and time data were also included to allow for potential effect of weather and time-varying influences on hospital admissions. CO showed the most significant (P < 0.05) relationship to cardiovascular admissions. An increment of 1 ppm in CO predicted an increase of 4% to 20% in cardiovascular admissions. Respiratory admissions were associated with PM10, which had about 1% increase in risk of admission per 10 ug/m3 increment in PM10. Exposure to CO and PM10 increases the risk of hospitalization for cardiovascular and respiratory illnesses in Klang Valley, Malaysia.

    To identify the factors associated with involuntary hospital admissions of technology-dependent children, in the municipality of Ribeirão Preto, São Paulo State, Brazil. A cross-sectional study, with a quantitative approach. After an active search, 124 children who qualified under the inclusion criteria, that is to say, children from birth to age 12, were identified. Data was collected in home visits to mothers or the people responsible for the children, through the application of a questionnaire. Analysis of the data followed the assumptions of the Generalized Linear Models technique. 102 technology-dependent children aged between 6 months and 12 years participated in the study, of whom 57% were male. The average number of involuntary hospital admissions in the previous year among the children studied was 0.71 (±1.29). In the final model the following variables were significantly associated with the outcome: age (OR=0.991; CI95%=0.985-0.997), and the number of devices (OR=0.387; CI95%=0.219-0.684), which were characterized as factors of protection and quantity of medications (OR=1.532; CI95%=1.297-1.810), representing a risk factor for involuntary hospital admissions in technology-dependent children. The results constitute input data for consideration of the process of care for technology-dependent children by supplying an explanatory model for involuntary hospital admissions for this client group.

    To investigate trends in hospital admissions involving suicidal behaviour in the Northern Territory (NT) resident population over the period 2001-2013. Estimates of age-standardised rates and average changes in the annual rate of hospital admissions involving suicidal behaviour were calculated by socio-demographic characteristics and types of suicidal behaviour. Overall rates for Indigenous admissions were 2.7 times higher than non-Indigenous admissions and had increased by almost twice as much. While male and female rates of admission were similar for both Indigenous and non-Indigenous residents, the average annual change in rates was greater for Indigenous females (13.4%) compared to males (8.8%) and for non-Indigenous males (7.7%) compared to females (5.2%). Younger and middle-aged Indigenous admissions experienced increasing rates of admissions, whilst trends were similar across age groups for non-Indigenous admissions. Admissions with a diagnosis of suicidal ideation increased the most across all groups. Trends in intentional self-harm admissions differed according to Indigenous status and sex. There have been substantial increases in hospital admissions involving suicidal behaviour in the NT, most markedly for Indigenous residents. Indigenous females and youth appear to be at increasing risk. The steep increase in suicidal ideation across all groups warrants further investigation. © The Royal Australian and New Zealand College of Psychiatrists 2016.

    The study objective was to assess the association between low serum creatinine value at admission and in-hospital mortality in hospitalized patients. This was a retrospective single-center cohort study conducted at a tertiary referral hospital. All hospitalized adult patients between 2011 and 2013 who had an admission creatinine value available were identified for inclusion in this study. Admission creatinine value was categorized into 7 groups: ≤0.4, 0.5 to 0.6, 0.7 to 0.8, 0.9 to 1.0, 1.1 to 1.2, 1.3 to 1.4, and ≥1.5 mg/dL. The primary outcome was in-hospital mortality. Logistic regression analysis was performed to obtain the odds ratio of in-hospital mortality for the various admission creatinine levels, using a creatinine value of 0.7 to 0.8 mg/dL as the reference group in the analysis of all patients and female patients and of 0.9 to 1.0 mg/dL in the analysis of male patients because it was associated with the lowest in-hospital mortality. Of 73,994 included patients, 973 (1.3%) died in the hospital. The association between different categories of admission creatinine value and in-hospital mortality assumed a U-shaped distribution, with both low and high creatinine values associated with higher in-hospital mortality. After adjustment for age, sex, ethnicity, principal diagnosis, and comorbid conditions, very low creatinine value (≤0.4 mg/dL) was significantly associated with increased mortality (odds ratio, 3.29; 95% confidence interval, 2.08-5.00), exceeding the risk related to a markedly increased creatinine value of ≥1.5 mg/dL (odds ratio, 2.56; 95% confidence interval, 2.07-3.17). The association remained significant in the subgroup analysis of male and female patients. Low creatinine value at admission is independently associated with increased in-hospital mortality in hospitalized patients. Copyright © 2016 Elsevier Inc. All rights reserved.

    To describe clinical associations of delirium in hospitalized patients and relationships to on admission presentation. Retrospective analysis of an administrative hospitalization database 1998-2007. Acute care hospitalizations in the New York State (NYS). Four categories of diagnosis related group (DRG) hospitalizations were extracted from a NYS administrative database: pneumonia, congestive heart failure, urinary tract/kidney infection (UTI), and lower extremity orthopedic surgery (LEOS) DRGs. These hospitalizations were examined for clinical associations with delirium coding both on and after admission. Delirium was coded in 0.8% of the cohort, of which an on admission diagnosis was present in 59%. On admission delirium was strongly associated with dementia (adjusted odds ratio 0, 95%CI 5.8-6.3) and with adverse drug effects (ADEs) (adjusted odds ratio 4.6, 95%CI 4.3, 5.0). After admission delirium was even more highly associated with ADEs (adjusted odds ratio 22.2, 95%CI 20.7-23.7). The UTI DRG category had the greatest proportion of on admission delirium. However after admission delirium was more common in the LEOS DRG category. Over time, there was a greater increase in delirium proportions in the UTI DRG category, and an overall increase in coding for encephalopathy states (potential alternative delirium descriptors). ADEs play an important role in delirium regardless of whether or not it is present on admission. While the finding that most delirium hospitalizations presented on admission suggests that delirium impacts more as a clinical admitting determinant, in-hospital prevention strategies may still have benefit in targeted settings where after admission delirium is more frequent, such as patients with LEOS.

    To investigate hospital admissions for non-cystic fibrosis bronchiectasis during July 1, 2008 to June 30, 2013; and to describe their distribution and annual cost in New Zealand. Admissions with a principal diagnosis of bronchiectasis (ICD10 J47), excluding cystic fibrosis, and length of stay <90 days were analysed by age, sex, ethnicity, socioeconomic deprivation, DHB, re-admissions and seasonality. There were 5,494 admissions with a mean annual rate of 25.7 (age adjusted rate 20.4) per 100,000. Admission rates peaked in childhood and in the elderly, and increased steeply with socioeconomic deprivation. Age-adjusted rates were 38% higher for women, 4.9-fold higher for Māori and 9.1-fold higher for Pacific peoples. Counties Manukau had the highest unadjusted rate for any DHB (49.4 per 100,000). The overall 30 day readmission rate was 12.4%. Admissions peaked in winter and spring. The estimated cost in financial year 2012/13 was NZD 5.34M. Hospital admissions for bronchiectasis are concentrated in socioeconomically disadvantaged young and elderly Māori and Pacific peoples; are more common in winter and spring, and incur a high annual cost. Evidence-based interventions to reduce the disproportionate burden of bronchiectasis in Māori and Pacific children and the elderly is a public health priority.

    To investigate the effect of social deprivation and ethnicity on inpatient admissions due to diabetes in England. Facility-based cross-sectional analysis. National Health Service (NHS) trusts in England reporting inpatient admissions with better than 80% data reporting quality from 2010-2011 (355 facilities). Non-obstetric patients over 16 years old in all NHS facilities in England. The sample size after exclusions was 5,147,859 all-cause admissions. The relative risk of inpatient admissions and readmissions due to diabetes adjusted for confounders. There were 445,504 diabetes-related hospital admissions in England in 2010, giving a directly (age-sex) standardized rate of 1049.0 per 100,000 population (95% confidence interval (CI): 1046.0-1052.1). The relative risk of inpatient admission in the most deprived quintile was 2.08 times higher than that of the least deprived quintile (95% CI: 2.02-2.14), and the effect of deprivation varied across ethnicities. About 30.1% of patients admitted due to diabetes were readmitted at least once due to diabetes. South Asians showed 2.62 times (95% CI: 2.51-2.74) higher admission risk. Readmission risk increased with IMD among white British but not other ethnicities. South Asians showed slightly lower risk of readmission than white British (0.86, 95% CI: 0.80-0.94). More deprived areas had higher rates of inpatient admissions and readmissions due to diabetes. South Asian British showed higher admission risk and lower readmission risk than white British. However, there was almost no difference by ethnicity in readmission due to diabetes. Higher rates of admission among deprived people may not necessarily reflect higher prevalence, but higher admission rates in south Asian British may be explained by their higher prevalence because their lower readmission risk suggests no inequality in primary care to prevent readmission. Better interventions in poorer areas, are needed to reduce these inequalities.

    Pneumonia poses a significant burden to the U.S. health-care system. However, there are few data focusing on severe pneumonia, particularly cases of pneumonia associated with specialized care in intensive care units (ICU). We used administrative and electronic medical record data from six integrated health care systems to estimate rates of pneumonia hospitalizations with ICU admissions among adults during 2006 through 2010. Pneumonia hospitalization was defined as either a primary discharge diagnosis of pneumonia or a primary discharge diagnosis of sepsis or respiratory failure with a secondary diagnosis of pneumonia in administrative data. ICU admissions were collected from internal electronic medical records from each system. Comorbidities were identified by ICD-9-CM codes coded during the current pneumonia hospitalization, as well as during medical visits that occurred during the year prior to the date of admission. We identified 119,537 adult hospitalizations meeting our definition for pneumonia. Approximately 19% of adult pneumonia hospitalizations had an ICU admission. The rate of pneumonia hospitalizations requiring ICU admission during the study period was 76 per 100,000 population/year; rates increased for each age-group with the highest rates among adults aged ≥85 years. Having a co-morbidity approximately doubled the risk of ICU admission in all age-groups. Our study indicates a significant burden of pneumonia hospitalizations with an ICU admission among adults in our cohort during 2006 through 2010, especially older age-groups and persons with underlying medical conditions. These findings reinforce current strategies aimed to prevent pneumonia among adults.

    Hospital re-admissions in decompensated cirrhosis are associated with worse patient outcomes. Hispanics have a disproportionately high prevalence of hepatitis C virus (HCV)-related morbidity and mortality. The goal of this study was to evaluate the factors affecting re-admission rates among Hispanics with HCV-related cirrhosis. A total of 292 consecutive HCV-related cirrhosis admissions (Hispanics 189, non-Hispanics 103) from January 2009 to December 2012 were retrospectively reviewed; 132 were cirrhosis-related re-admissions. The statistical analysis was performed using STATA version 11.1. Chi-square/Fisher's exact and Student's t-tests were used to compare categorical and continuous variables, respectively. Multivariate logistic regression analysis was performed to identify predictors for hospital readmissions. Among the 132 cirrhosis-related readmissions, 71% were Hispanics while 29% were non-Hispanics (P=0.035). Hepatic encephalopathy (HE) and esophageal variceal hemorrhage were the most frequent causes of the first and subsequent readmissions. Hispanics with readmissions had a higher Child-Turcotte-Pugh (CTP) class (B and C) and higher model for end-stage liver disease (MELD) scores (≥15), as well as a higher incidence of alcohol use, HE, spontaneous bacterial peritonitis, hepatocellular carcinoma, and varices (P<0.05). The majority of the study patients (81%) had MELD scores <15. Multivariate regression analysis identified alcohol use (OR 2.63; 95%CI 1.1-6.4), HE (OR 5.5; 95%CI 2-15.3), varices (OR 3.2; 95%CI 1.3-8.2), and CTP class (OR 3.3; 95%CI 1.4-8.1) as predictors for readmissions among Hispanics. CTP classes B and C, among other factors, were the major predictors for hospital readmissions in Hispanics with HCV-related cirrhosis. The majority of these readmissions were due to HE and variceal hemorrhage.

    This study was undertaken to determine whether there is an association between air pollutants levels and hospital admissions for asthma in Kaohsiung, Taiwan. Hospital admissions for asthma and ambient air pollution data for Kaohsiung were obtained for the period from 1996 through 2003. The relative risk of hospital admission was estimated using a case-crossover approach, controlling for weather variables, day of the week, seasonality, and long-term time trends. In the single-pollutant models, on warm days ({>=}25{sup o}C) statistically significant positive associations were found in all pollutants except sulfur dioxide. On cool days ({<=} 25{sup o}C) all pollutants were significantly associatedmore » with asthma admissions. For the two pollutant models, CO and O{sub 3} were significant in combination with each of the other four pollutants on warm days. On cool days NO{sub 2} remained statistically significant in all the two-pollutant models. This study provides evidence that higher levels of ambient pollutants increase the risk of hospital admissions for asthma.« less

    Objective This paper describes the potential use of multiple influenza surveillance data to forecast hospital admissions for respiratory diseases. Introduction A sudden surge in hospital admissions in public hospital during influenza peak season has been a challenge to healthcare and manpower planning. In Hong Kong, the timing of influenza peak seasons are variable and early short-term indication of possible surge may facilitate preparedness which could be translated into strategies such as early discharge or reallocation of extra hospital beds. In this study we explore the potential use of multiple routinely collected syndromic data in the forecast of hospital admissions. Methods A multivariate dynamic linear time series model was fitted to multiple syndromic data including influenza-like illness (ILI) rates among networks of public and private general practitioners (GP), and school absenteeism rates, plus drop-in fever count data from designated flu clinics (DFC) that were created during the pandemic. The latent process derived from the model has been used as a measure of the influenza activity [1]. We compare the cross-correlations between estimated influenza level based on multiple surveillance data and GP ILI data, versus accident and emergency hospital admissions with principal diagnoses of respiratory diseases and pneumonia & influenza (P&I). Results The estimated influenza activity has higher cross-correlation with respiratory and P&I admissions (ρ=0.66 and 0.73 respectively) compared to that of GP ILI rates (Table 1). Cross correlations drop distinctly after lag 2 for both estimated influenza activity and GP ILI rates. Conclusions The use of a multivariate method to integrate information from multiple sources of influenza surveillance data may have the potential to improve forecasting of admission surge of respiratory diseases.

    Hospital Episode Statistics data are used for healthcare planning and hospital reimbursements. Reliability of these data is dependent on the accuracy of individual hospitals reporting Secondary Uses Service (SUS) which includes hospitalisation. The number and coding accuracy for Parkinson's disease hospital admissions at a tertiary centre in Birmingham was assessed. Retrospective, routine-data-based study. A retrospective electronic database search for all Parkinson's disease patients admitted to the tertiary hospital over a 4-year period (2009-2013) was performed on the SUS database using International Classification of Disease codes, and on the local inpatient electronic prescription database, Prescription and Information Communications System, using medication prescriptions. Capture-recapture methods were used to estimate the number of patients and admissions missed by both databases. From the two databases, between July 2009 and June 2013, 1068 patients with Parkinson's disease accounted for 1999 admissions. During these admissions, the Parkinson's disease was coded as a primary or secondary diagnosis. Ninety-one percent of these admissions were recorded on the SUS database. Capture-recapture methods estimated that the number of Parkinson's disease patients admitted during this period was 1127 patients (95% confidence interval: 1107-1146). A supplementary search of both SUS and Prescription and Information Communications System was undertaken using the hospital numbers of these 1068 patients. This identified another 479 admissions. SUS database under-estimated Parkinson's disease admissions by 27% during the study period. The accuracy of disease coding is critical for healthcare policy planning and must be improved. If the under-reporting of Parkinson's disease admissions on the SUS database is repeated nationally, expenditure on Parkinson's disease admissions in England is under-estimated by approximately £61 million per year.

    Data regarding temporal trends in per capita paediatric hospital presentations and admissions are required to inform health system and workforce planning. Emergency Department (ED) presentations and admissions to the University Hospital Geelong among patients aged 0 to 16 years over a 12-month period (2012-2013) were determined by review of hospital records and then compared with similar data collected during 1996/1997. 1 During each period, the Geelong region was serviced by a single ED, enabling us to estimate per capita presentation and admission rates. Since 1996/1997, per capita paediatric presentations to the ED increased from 643 to 1837 per 10 000 (186%; 95% confidence interval 181% to 191%). Moreover, the proportion of paediatric ED presentations resulting in hospital admission increased from 12.3% to 18.3% (49%; 95% confidence interval 39% to 59%). There has been a substantial absolute and per capita increase in paediatric ED presentations and hospital admissions since the 1990s. These trends place an increasing burden on the public hospital system, and strategies are required to promote paediatric acute care in the ambulatory setting. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    Exposure to air pollutants is one of the factors responsible for hospitalizations due to pneumonia among children. This has considerable financial cost, along with social cost. A study to identify the role of this exposure in relation to hospital admissions due to pneumonia among children up to 10 years of age was conducted. Ecological time series study using data from São José dos Campos, Brazil. Daily data on hospitalizations due to pneumonia and on the pollutants CO, O3, PM10 and SO2, temperature and humidity in São José dos Campos, in 2012, were analyzed. A generalized additive model of Poisson's regression was used. Relative risks for hospitalizations due to pneumonia, according to lags of 0-5 days, were estimated. The population-attributable fraction, number of avoidable hospitalizations and cost savings from avoidable hospitalizations were calculated. There were 539 admissions. Exposure to CO and O3 was seen to be associated with hospitalizations, with risks of 1.10 and 1.15 on the third day after exposure to increased CO concentration of 200 ppb and ozone concentration of 20 µg/m3. Exposure to the pollutants of particulate matter and sulfur dioxide were not shown to be associated with hospitalizations. Decreases in CO and ozone concentrations could lead to 49 fewer hospitalizations and cost reductions of R$ 39,000.00. Exposure to certain air pollutants produces harmful effects on children's health, even in a medium-sized city. Public policies to reduce emissions of these pollutants need to be implemented.

    Although the majority of children with an unplanned admission to the hospital are admitted through the emergency department (ED), direct admissions constitute a significant proportion of hospital admissions nationally. Despite this, past studies of children have not characterized direct admission practices or outcomes. Pneumonia is the leading cause of pediatric hospitalization in the United States, providing an ideal lens to examine variation and outcomes associated with direct admissions. To describe rates and patterns of direct admission in a large sample of US hospitals and to compare resource utilization and outcomes between children with pneumonia admitted directly to a hospital and those admitted from an ED. Retrospective cohort study of children 1 to 17 years of age with pneumonia who were admitted to hospitals contributing data to Perspective Data Warehouse. We developed hierarchical generalized linear models to examine associations between admission type and outcomes. Outcome measures included (1) length of stay, (2) high turnover hospitalization, (3) total hospital cost, (4) transfer to the intensive care unit, and (5) readmission within 30 days of hospital discharge. A total of 19,736 children from 278 hospitals met eligibility criteria, including 7100 (36.0%) who were admitted directly and 12,636 (64.0%) through the ED. Rates of direct admission varied considerably across hospitals, with a median direct admission rate of 33.3% (interquartile range, 11.1%-50.0%). Children admitted directly were more likely to be white, to have private health insurance, and to be admitted to small, general community hospitals. In adjusted models, children admitted directly had a 9% higher length of stay (risk ratio, 1.09 [95% CI, 1.07-1.11]), 39% lower odds of high turnover hospitalization (odds ratio [OR], 0.61 [95% CI, 0.56-0.66]), and 12% lower cost (risk ratio, 0.88 [95% CI, 0.87-0.90]) than those admitted through the ED, with no significant differences in transfers

    The factors that influence hospital admissions for schizophrenia in Costa Rica were investigated in people of both sexes who were admitted for the first time with this diagnosis (codes 295.0 to 295.9 of the International Classification of Diseases, Ninth Revision) in the period 1979 to 1981. Annual incidence rates were calculated using the number of hospitalized cases and the total population of the country. The average annual incidence was found to be 48.2 cases per 100000 inhabitants. High frequencies of first admissions were seen among males 40 to 44 years of age and females 45 to 49. Incidence was highest among unmarried women, followed by divorced women. There was a significant inverse relationship between educational attainment and rates of admission for schizophrenia, and incidence rates were highest among unemployed women and housewives. The association between rate of hospitalization for schizophrenia and 10 characteristics of the cantons was studied by means of logistic regression. Only two variables-the distance between the canton's principal town and the hospital and the volume of coffee harvest per resident-showed a direct significant association with admission rates for schizophrenia. The cantons which had the highest number of births of children who were diagnosed as schizophrenic in adulthood were those closest to the psychiatric hospital and those that had a low level of industrial or agricultural activity, low population density, and high proportions of single or divorced persons.

    Rising admissions from emergency departments (EDs) to hospitals are a primary concern for many healthcare systems. The issue of how to differentiate urgent admissions from non-urgent or even elective admissions is crucial. We aim to develop a model for classifying inpatient admissions based on a patient's primary diagnosis as either emergency care or elective care and predicting urgency as a numerical value. We use supervised machine learning techniques and train the model with physician-expert judgments. Our model is accurate (96%) and has a high area under the ROC curve (>.99). We provide the first comprehensive classification and urgency categorization for inpatient emergency and elective care. This model assigns urgency values to every relevant diagnosis in the ICD catalog, and these values are easily applicable to existing hospital data. Our findings may provide a basis for policy makers to create incentives for hospitals to reduce the number of inappropriate ED admissions.

    Numerous studies have identified short-term effects of air pollution on morbidity in North America and Europe. The effects of air pollution may differ by region of the world. Evidence on air pollution and morbidity in Asia is limited. We investigated associations between ambient air pollution and hospital admissions in eight Korean cities for 2003-2008. We applied a two-stage Bayesian hierarchical model to estimate city-specific effects and the overall effects across the cities. We considered lagged effects of pollutants by cause (allergic disease, asthma, selected respiratory disease, and cardiovascular disease), sex, and age (0-14, 15-64, 65-74, and ≥ 75 years). We found evidence of associations between hospital admissions and short-term exposure to air pollution. An interquartile range (IQR) increase in PM10 (30.7 µg/m) was associated with an overall increase of 2.2% (95% posterior interval = 0.5%-3.9%), 2.8% (1.3%-4.4%), 1.7% (0.9%-2.6%), and 0.7% (0.0%-1.4%) in allergic, asthma, selected respiratory, and cardiovascular admissions, respectively. For NO2 (IQR 12.2 ppb), the corresponding figures were 2.3% (0.6%-4.0%), 2.2% (0.3%-4.1%), 2.2% (0.6%-3.7%), and 2.2% (1.1%-3.4%). For O3, we found positive associations for all the studied diagnoses except cardiovascular disease. SO2 was associated with hospital admissions for selected respiratory or cardiovascular causes, whereas O3 was negatively associated with cardiovascular admissions. We found suggestive evidence for stronger associations in younger and older age groups. Associations were similar for men and women. Ambient air pollution was associated with increased risk of hospital admissions in Korea. Results suggest increased susceptibility among the young or the elderly for pollution effects on specific diseases.

Data Sources/Study Setting A large manufacturing company instituted the hospital safety incentive (HSI) for union employees. The HSI gave union patients a financial incentive to choose hospitals that met the Leapfrog Group's three patient safety “leaps.” The analysis merges data from four sources: claims and enrollment data from the company, the American Hospital Association, the AHRQ HCUP-SID, and a state Office of the Insurance Commissioner. Study Design Changes in hospital admissions’ patterns for union and nonunion employees using a difference-in-difference design. We estimate the probability of choosing a specific hospital from a set of available alternatives using conditional logistic regression. Principal Findings Patients affiliated with the engineers’ union and admitted for a medical diagnosis were 2.92 times more likely to select a hospital designated as safer in the postperiod than in the preperiod, while salaried nonunion (SNU) patients (not subject to the financial incentive) were 0.64 times as likely to choose a compliant hospital in the post- versus preperiod. The difference-in-difference estimate, which is based on the predictions of the conditional logit model, is 0.20. However, the machinists’ union was also exposed to the incentive and they were no more likely to choose a safer hospital than the SNU patients. The incentive did not have an effect on patients admitted for a surgical diagnosis, regardless of union status. All patients were averse to travel time, but those union patients selecting an incentive hospital were less averse to travel time. Conclusions Patient price incentives and quality/safety information may influence hospital selection decisions, particularly for medical admissions, though the optimal incentive level for financial return to the plan sponsor is not clear.

    Recent studies in the USA and northern Europe have shown an increase in community-acquired pneumonia (CAP). In southern Europe, this increase has not yet been documented. We carried out a retrospective analysis from encoded information from the Portuguese database for hospital admissions that included all individuals aged ≥18 years, with a primary diagnosis of pneumonia, who were discharged between 2000 and 2009. We excluded patients infected with HIV, individuals immunocompromised as a result of anti-cancer or immunosuppressive treatment, and transplant recipients. Of the 294 027 admissions for CAP, 56% were male. The mean age was 73.1 years and the median age 77 years. Between 2000 and 2009, there was a 5% increase in the average age of patients admitted with CAP. Admissions for CAP represented 3.7% of total admissions of adult patients. The average annual rate of hospital admissions for adults with CAP was 3.61 per 1000 total population, rising to 13.4 for those aged ≥65 years. Between 2000-2004 and 2005-2009 the average annual rate of hospital admission for CAP per 1000 population increased by 28.2%. Hospital admissions for CAP in Portugal increased between 2000 and 2009. It has grown consistently over time, varying according to age with males over-represented.

    The incidence and prevalence of acute and chronic pancreatitis have increased in Western countries. It is likely, the number of hospital admissions has increased correspondingly. To analyze the trends in hospital admissions in the Netherlands for acute and chronic pancreatitis from 1992 to 2004 and to forecast the number of admissions up to 2010. Analysis of hospital admissions for acute and chronic pancreatitis accumulated in a nationwide database. Curve fitting regression models were used to explore future trends. The number of acute pancreatitis admissions rose in 1992-2004 from 1,785 to 3,120 (74.8% increase). The overall 'annual number' of acute pancreatitis admissions increased from 11.8 to 19.2 per 100,000 person-years. The linear regression model predicted 3,205 [95% confidence intervals (CI), 3,111-3,299] and 3,537 (95% CI, 3,429-3,645) admissions for 2007 and 2010, respectively, a further increase of at least 9.9% in 2010 compared with 2004. In the 12-year time period, chronic pancreatitis admissions showed an increase of 75.4% (from 790 to 1,386). The overall 'annual number' of chronic pancreatitis admissions increased from 5.2 to 8.5 per 100,000 person-years. The cubic regression model predicted 1868 (95% CI, 1,619-2,117) and 3,173 (95% CI, 2,456-3,890) admissions for 2007 and 2010, respectively, an additional increase of 77.2% in 2010 compared with 2004. Hospital admissions for acute and chronic pancreatitis have increased substantially from 1992-2004. This trend will most likely continue for the near future and the burden and costs to the Dutch health care system will increase accordingly.

    National Early Warning Score (NEWS) is increasingly used in UK hospitals. However, there is only limited evidence to support the use of pre-hospital early warning scores. We hypothesised that pre-hospital NEWS was associated with death or critical care escalation within the first 48 h of hospital stay. Planned secondary analysis of a prospective cohort study at a single UK teaching hospital. Consecutive medical ward admissions over a 20-day period were included in the study. Data were collected from ambulance report forms, medical notes and electronic patient records. Pre-hospital NEWS was calculated retrospectively. The primary outcome was a composite of death or critical care unit escalation within 48 h of hospital admission. The secondary outcome was length of hospital stay. 189 patients were included in the analysis. The median pre-hospital NEWS was 3 (IQR 1-5). 13 patients (6.9%) died or were escalated to the critical care unit within 48 h of hospital admission. Pre-hospital NEWS was associated with death or critical care unit escalation (OR, 1.25; 95% CI, 1.04-1.51; p = 0.02), but NEWS on admission to hospital was more strongly associated with this outcome (OR, 1.52; 95% CI, 1.18-1.97, p < 0.01). Neither was associated with hospital length of stay. Pre-hospital NEWS was associated with death or critical care unit escalation within 48 h of hospital admission. NEWS could be used by ambulance crews to assist in the early triage of patients requiring hospital treatment or rapid transport. Further cohort studies or trials in large samples are required before implementation.

    The UK government is pursuing policies to improve primary care access, as many patients visit accident and emergency (A and E) departments after being unable to get suitable general practice appointments. Direct admission to hospital via a general practitioner (GP) averts A and E use, and may reduce total hospital costs. It could also enhance the continuity of information between GPs and hospital doctors, possibly improving healthcare outcomes. To determine whether primary care access is associated with the route of emergency admission-via a GP versus via an A and E department. Retrospective analysis of national administrative data from English hospitals for 2011-2012. Adults admitted in an emergency (unscheduled) for ≥1 night via a GP or an A and E department formed the study population. The measure of primary care access-the percentage of patients able to get a general practice appointment on their last attempt-was derived from a large, nationally representative patient survey. Multilevel logistic regression was used to estimate associations, adjusting for patient and admission characteristics. The analysis included 2 322 112 emergency admissions (81.9% via an A and E department). With a 5 unit increase in the percentage of patients able to get a general practice appointment on their last attempt, the adjusted odds of GP admission (vs A and E admission) was estimated to increase by 15% (OR 1.15, 95% CI 1.12 to 1.17). The probability of GP admission if ≥95% of appointment attempts were successful in each general practice was estimated to be 19.6%. This probability reduced to 13.6% when <80% of appointment attempts were successful. This equates to 139 673 fewer GP admissions (456 232 vs 316 559) assuming no change in the total number of admissions. Associations were consistent in direction across geographical regions of England. Among hospital inpatients admitted as an emergency, patients registered to more accessible general practices were more

    Saharan dust intrusions make a major contribution to levels of particulate matter (PM) present in the atmosphere of large cities. We analysed the impact of different PM fractions during periods with and without Saharan dust intrusions, using time-series analysis with Poisson regression models, based on: concentrations of coarse PM (PM10 and PM10-2.5) and fine PM (PM2.5); and daily all-, circulatory- and respiratory-cause hospital admissions. While periods without Saharan dust intrusions were marked by a statistically significant association between daily mean PM2.5 concentrations and all- and circulatory-cause hospital admissions, periods with such intrusions saw a significant increase in respiratory-cause admissions associated with fractions corresponding to PM10 and PM10-2.5.

    We examined the associations between the daily variations of air pollutants and hospital admissions for respiratory diseases in İstanbul, the largest city of Turkey. A time series analysis of counts of daily hospital admissions and outdoor air pollutants was performed using single-pollutant Poisson generalized linear model (GLM) while controlling for time trends and meteorological factors over a 3-year period (2013-2015) at different time lags (0-9 days). Effects of the pollutants (Excess Risk, ER) on current-day (lag 0) hospital admissions to the first ten days (lag 9) were determined. Data on hospital admissions, daily mean concentrations of air pollutants of PM 10 , PM 2.5 and NO 2 and daily mean concentrations of temperature and humidity of İstanbul were used in the study. The analysis was conducted among people of all ages, but also focused on different sexes and different age groups including children (0-14 years), adults (35-44 years) and elderly (≥65 years). We found significant associations between air pollution and respiratory related hospital admissions in the city. Our findings showed that the relative magnitude of risks for an association of the pollutants with the total respiratory hospital admissions was in the order of: PM 2.5 , NO 2 , and PM 10 . The highest association of each pollutant with total hospital admission was observed with PM 2.5 at lag 4 (ER = 1.50; 95% CI = 1.09-1.99), NO 2 at lag 4 (ER = 1.27; 95% CI = 1.02-1.53) and PM 10 at lag 0 (ER = 0.61; 95% CI = 0.33-0.89) for an increase of 10 μg/m3 in concentrations of the pollutants. In conclusion, our study showed that short-term exposure to air pollution was positively associated with increased respiratory hospital admissions in İstanbul during 2013-2015. As the first air pollution hospital admission study using GLM in İstanbul, these findings may have implications for local environmental and social policies. Copyright © 2017 Elsevier Ltd.

    For many years an amalgam containing metallic mercury, which has been associated with neurological and renal diseases, has been used in dentistry. In this nationwide study we compared hospital admissions due to neurological and renal diseases among dentists and dental assistants to admissions in controls. This register-based cohort study included all Danish workers employed in dental clinics, general practitioners' clinics or lawyers' offices between 1964 and 2006. We compared dentists with general practitioners and lawyers, and dental assistants with medical secretaries, nurses and legal secretaries. We also compared dentists and dental assistants employed during periods with high occupational mercury exposure with dentists and dental assistants employed during periods with less mercury exposure. We followed all subjects in a nationwide register of hospital admissions. We analysed risk of neurological diseases, Parkinson's disease and renal diseases using a Cox regression model. The cohort consisted of 122,481 workers including 5371 dentists and 33,858 dental assistants. For neurological diseases, no association was observed for dental assistants, while for dentists an increasing risk for periods with less mercury exposure was observed. Among dental assistants, a negative association between employment length and risk of neurological disease was observed. Admissions for renal disease among dental assistants were increased during periods with less mercury exposure compared with controls. For dentists a non-significant increased risk was observed between employment length and renal disease risk. Our nationwide study does not indicate that occupational exposure to mercury increases the risk of hospital admissions for neurological, Parkinson's or renal diseases.

    From an analysis of data from 23 European countries to determine the impact of primary care on avoidable hospital admissions for uncontrolled diabetes it appeared that, contrary to expectation, countries with strong primary care did not have a lower rate of avoidable hospital admission. It is clear that Roemer's law, 'a bed built is a bed filled,' still applies. However, the validity of this sort of analysis can be questioned, as these data are highly aggregated, and registration quality differs between countries. It is also questionable if these datasets can be considered as 'big data' as there are relatively small numbers per country. Big data analyses are useful for discerning patterns and formulating hypotheses, but not for proving causality. An unwanted side effect of this kind of analysis might be that policymakers use these not so valid results to underpin their policy to their advantage.

    OBJECTIVE: To study the trend in hospital admission rates for heart failure in the Netherlands from 1980 to 1993. DESIGN: All hospital admissions in the Netherlands with a principal discharge diagnosis of heart failure were analysed. In addition, individual records of heart failure patients from a subset of 7 hospitals were analysed to estimate the frequency and timing of readmissions. RESULTS: The total number of discharges for men increased from 7377 in 1980 to 13 022 in 1993, and for women from 7064 to 12 944. From 1980 through 1993 age adjusted discharge rates rose 48% for men and 40% for women. Age adjusted in-hospital mortality for heart failure decreased from 19% in 1980 to 15% in 1993. For all age groups in-hospital mortality for men was higher than for women. The mean length of hospital admissions in 1993 was 14.0 days for men and 16.4 days for women. A review of individual patient records from a 6.3% sample of all hospital admissions in the Netherlands indicated that within a 2 year period 18% of the heart failure patients were admitted more than once and 5% more than twice. CONCLUSIONS: For both men and women a pronounced increase in age adjusted discharge rates for heart failure was observed in the Netherlands from 1980 to 1993. Readmissions were a prominent feature among heart failure patients. Higher survival rates after acute myocardial infarction and the longer survival of patients with heart disease, including heart failure may have contributed to the observed increase. The importance of advances in diagnostic tools and of possible changes in admission policy remain uncertain. PMID:8944582

    Since the publication of the first analysis of Medicare payment error rates in 1998, the Office of Inspector General and the Centers for Medicare & Medicaid Services have focused resources on Medicare payment error prevention programs, now referred to as the Hospital Payment Monitoring Program. The purpose of the Hospital Payment Monitoring Program is to educate providers of Medicare Part A services in strategies to improve medical record documentation and decrease the potential for payment errors through appropriate claims completion. Although the payment error rates by state (and dollars paid in error) have decreased significantly, opportunities for improvement remain as demonstrated in this study of nine hospitals with a high proportion of short-term admissions over time. Previous studies by the Quality Improvement Organization had focused on inpatient stays of 1 day or less, a primary target due to the large amount of Medicare dollars spent on these admissions. Random review of Louisiana Medicare admissions revealed persistent medical record documentation and process issues regardless of length of stay as well as the opportunity for significant future savings to the Medicare Trust Fund. The purpose of this study was to determine whether opportunities for improvement in reduction of payment error continue to exist for inpatient admissions of greater than 1 day, despite focused education provided by Louisiana Health Care Review, the Louisiana Medicare Quality Improvement Organization, from 1999 to 2005, and to work individually with the nine selected hospitals to assist them in reducing the number of unnecessary short-term admissions and billing errors in each hospital by a minimum of 50% by the end of the study period.

    Summary Background The annual number of hospital admissions and in-hospital deaths due to severe acute lower respiratory infections (ALRI) in young children worldwide is unknown. We aimed to estimate the incidence of admissions and deaths for such infections in children younger than 5 years in 2010. Methods We estimated the incidence of admissions for severe and very severe ALRI in children younger than 5 years, stratified by age and region, with data from a systematic review of studies published between Jan 1, 1990, and March 31, 2012, and from 28 unpublished population-based studies. We applied these incidence estimates to population estimates for 2010, to calculate the global and regional burden in children admitted with severe ALRI in that year. We estimated in-hospital mortality due to severe and very severe ALRI by combining incidence estimates with case fatality ratios from hospital-based studies. Findings We identified 89 eligible studies and estimated that in 2010, 11·9 million (95% CI 10·3–13·9 million) episodes of severe and 3·0 million (2·1–4·2 million) episodes of very severe ALRI resulted in hospital admissions in young children worldwide. Incidence was higher in boys than in girls, the sex disparity being greatest in South Asian studies. On the basis of data from 37 hospital studies reporting case fatality ratios for severe ALRI, we estimated that roughly 265 000 (95% CI 160 000–450 000) in-hospital deaths took place in young children, with 99% of these deaths in developing countries. Therefore, the data suggest that although 62% of children with severe ALRI are treated in hospitals, 81% of deaths happen outside hospitals. Interpretation Severe ALRI is a substantial burden on health services worldwide and a major cause of hospital referral and admission in young children. Improved hospital access and reduced inequities, such as those related to sex and rural status, could substantially decrease mortality related to such infection

    The aim of this paper is to analyze the relationship between North Atlantic Oscillation (NAO), meteorological variables, air pollutants, and hospital admissions due to diseases of circulatory systems in Lisbon (Portugal) during winter months (2003-2012). This paper is one of the few studies analyzing the impact of NAO on health through its influence on thermal stress and air pollution and is the first to be conducted in Lisbon. This study uses meteorological data (synthetized into a thermal comfort index), air pollutant metrics, and the NAO index (all clustered in 10-day cycles to overcome daily variability of the NAO index). The relationship between morbidity, thermal comfort index, NAO index, and air pollutants was explored through several linear models adjusted to seasonality through a periodic function. The possible indirect effect between the NAO index and hospital admissions was tested, assuming that NAO (independent variable) is affecting hospital admissions (outcome variable) through thermal discomfort and/or pollution levels (tested as individual mediators). This test was conducted through causal mediation analysis and adjusted for seasonal variation. The results from this study suggest a possible indirect relationship between NAO index and hospital admissions. Although NAO is not significantly associated with hospital admissions, it is significantly associated with CO, PM 2.5 , NO, and SO 2 levels, which in turn increase the probability of hospitalization. The discomfort index (built with temperature and relative humidity) is significantly associated with hospital admissions, but its variability is not explained by the NAO index. This study highlights the impacts of the atmospheric circulation patterns on health. Furthermore, understanding the influence of the atmospheric circulation patterns can support the improvement of the existing contingency plans.

    The shift from an industrial to a service-based economy has seen a decline in work-related injuries (WRIs) and mortality. How this relates to migrant workers, who traditionally held high-risk jobs is unknown. This study examined deaths and hospital admissions from WRI, among foreign and Australian-born workers. Tabulated population data from the 1991 to 2011 censuses, national deaths 1991-2002 and hospital admission for 2001-10. Direct age standardised mortality and hospital admission rates (DSRs) and rate ratios (RRs) were derived to examine differences in work-related mortality/hospital admissions by gender, country of birth, employment skill level and years of residence in Australia. DSRs and RRs were generally lower or no different between Australian and foreign-born workers. Among men, mortality DSRs were lower for nine of 16 country of birth groups, and hospital admissions DSRs for 14 groups. An exception was New Zealand-born men, with 9% (95%CI 9-13) excess mortality and 24% (95%CI 22-26) excess hospital admissions. Four decades ago, foreign-born workers were generally at higher risk of WRI than Australian-born. This pattern has reversed. The local-born comprise 75% of the population and a pro-active approach to health and safety regulation could achieve large benefits. © 2015 Public Health Association of Australia.

    Background Increasing severe vegetation fires worldwide has been attributed to both global environmental change and land management practices. However there is little evidence concerning the population health effects of outdoor air pollution derived from biomass fires. Frequent seasonal bushfires near Darwin, Australia provide an opportunity to examine this issue. We examined the relationship between atmospheric particle loadings <10 microns in diameter (PM10), and emergency hospital admissions for cardio-respiratory conditions over the three fire seasons of 2000, 2004 and 2005. In addition we examined the differential impacts on Indigenous Australians, a high risk population subgroup. Methods We conducted a case-crossover analysis of emergency hospital admissions with principal ICD10 diagnosis codes J00–J99 and I00–I99. Conditional logistic regression models were used to calculate odds ratios for admission with 10 μg/m3 rises in PM10. These were adjusted for weekly influenza rates, same day mean temperature and humidity, the mean temperature and humidity of the previous three days, days with rainfall > 5 mm, public holidays and holiday periods. Results PM10 ranged from 6.4 – 70.0 μg/m3 (mean 19.1). 2466 admissions were examined of which 23% were for Indigenous people. There was a positive relationship between PM10 and admissions for all respiratory conditions (OR 1.08 95%CI 0.98–1.18) with a larger magnitude in the Indigenous subpopulation (OR1.17 95% CI 0.98–1.40). While there was no relationship between PM10 and cardiovascular admissions overall, there was a positive association with ischaemic heart disease in Indigenous people, greatest at a lag of 3 days (OR 1.71 95%CI 1.14–2.55). Conclusion PM10 derived from vegetation fires was predominantly associated with respiratory rather than cardiovascular admissions. This outcome is consistent with the few available studies of ambient biomass smoke pollution. Indigenous people appear to be at higher risk

    Demographic changes and the economic situation of the recent years have conditioned a turning point in health policies, which have decided to progressively prioritize chronicity care programs. Given that hospital costs were concentrated in attention to patients with chronic diseases, reduction on admissions is now a priority target. Meanwhile, we state that among the obviously community handling paradigmatic aim for those patients and the current care situation, there is a long way to do that should be done gradually. According to the current scientific evidence: Is it sensible to assume that there is a proper level of admissions or is it better for the patients to reduce the number of admissions? Is it possible to operationally and reliably define which hospital admissions are avoidable? Is it harmful to a patient and to the health care system to admit a patient with multiple chronic disease? Maybe are hospital admissions are avoidable and readmissions are indicators of a fragmented health care system? Given that situation, a reasonable approach requires firstly a critical analysis of the various realities of care (microsystems) and a systematic review of the scientific evidence-breaking, and rejecting some topics if necessary. Secondly, we should bring all this knowledge to clinical practice, conciliating «what» and the know-how, individual and population view, sole disease and multimorbidity, and finally clinical approach and health planning.

    Time spent in the emergency department (ED) before admission to hospital is often considered an important key performance indicator (KPI). Throughout Australia and New Zealand, there is no standard definition of 'time of admission' for patients admitted through the ED. By using data submitted to the Australian and New Zealand Intensive Care Society Adult Patient Database, the aim was to determine the differing methods used to define hospital admission time and assess how these impact on the calculation of time spent in the ED before admission to an intensive care unit (ICU). Between March and December of 2010, 61 hospitals were contacted directly. Decision methods for determining time of admission to the ED were matched to 67,787 patient records. Univariate and multivariate analyses were conducted to assess the relationship between decision method and the reported time spent in the ED. Four mechanisms of recording time of admission were identified, with time of triage being the most common (28/61 hospitals). Reported median time spent in the ED varied from 2.5 (IQR 0.83-5.35) to 5.1 h (2.82-8.68), depending on the decision method. After adjusting for illness severity, hospital type and location, decision method remained a significant factor in determining measurement of ED length of stay. Different methods are used in Australia and New Zealand to define admission time to hospital. Professional bodies, hospitals and jurisdictions should ensure standardisation of definitions for appropriate interpretation of KPIs as well as for the interpretation of studies assessing the impact of admission time to ICU from the ED. WHAT IS KNOWN ABOUT THE TOPIC?: There are standards for the maximum time spent in the ED internationally, but these standards vary greatly across Australia. The definition of such a standard is critically important not only to patient care, but also in the assessment of hospital outcomes. Key performance indicators rely on quality data to improve decision

    Fine particulate matter (PM 2.5 ) emissions from vegetation fires can be transported over long distances and may cause significant air pollution episodes far from the fires. However, epidemiological evidence on health effects of vegetation-fire originated air pollution is limited, particularly for mortality and cardiovascular outcomes. We examined association between short-term exposure to long-range transported PM 2.5 from vegetation fires and daily mortality due to non-accidental, cardiovascular, and respiratory causes and daily hospital admissions due to cardiovascular and respiratory causes in the Helsinki metropolitan area, Finland. Days significantly affected by smoke from vegetation fires between 2001 and 2010 were identified using air quality measurements at an urban background and a regional background monitoring station, and modelled data on surface concentrations of vegetation-fire smoke. Associations between daily PM 2.5 concentration and health outcomes on i) smoke-affected days and ii) all other days (i.e. non-smoke days) were analysed using Poisson time series regression. All statistical models were adjusted for daily temperature and relative humidity, influenza, pollen, and public holidays. On smoke-affected days, 10µg/m 3 increase in PM 2.5 was associated with a borderline statistically significant increase in cardiovascular mortality among total population at a lag of three days (12.4%, 95% CI -0.2% to 26.5%), and among the elderly (≥65 years) following same-day exposure (13.8%, 95% CI -0.6% to 30.4%) and at a lag of three days (11.8%, 95% CI -2.2% to 27.7%). Smoke day PM 2.5 was not associated with non-accidental mortality or hospital admissions due to cardiovascular causes. However, there was an indication of a positive association with hospital admissions due to respiratory causes among the elderly, and admissions due to chronic obstructive pulmonary disease or asthma among the total population. In contrast, on non-smoke days PM 2.5 was

    Data on the epidemiology of alcoholic cirrhosis, especially in Asian countries, are limited. We compared the temporal evolution of patterns of alcoholic and nonalcoholic cirrhosis over the last decade. We retrospectively examined the inpatient datasets of five referral centers during 2002 and 2011. The study included patients who were admitted due to specific complications of liver cirrhosis. We compared the causes of hospital admissions and in-hospital deaths between patients with alcoholic and nonalcoholic cirrhosis. Among the included 2,799 hospitalizations (2,165 patients), 1,496 (1,143 patients) were from 2002, and 1,303 (1,022 patients) were from 2011. Over time, there was a reduction in the rate of hepatic encephalopathy (HE) as a cause of hospitalization and an increase in the rate of hepatocellular carcinoma. Deaths that were attributable to HE or spontaneous bacterial peritonitis (SBP) significantly decreased, whereas those due to hepatorenal syndrome (HRS) significantly increased over time in patients with alcoholic cirrhosis. However, in patients with nonalcoholic cirrhosis, hepatic failure and HRS remained the principal causes of in-hospital death during both time periods. The major causes of in-hospital deaths have evolved from acute cirrhotic complications, including HE or SBP to HRS in alcoholic cirrhosis, whereas those have remained unchanged in nonalcoholic cirrhosis during the last decade.

    Children with clefts have an increased tendency for dental anomalies and caries. To determine the pattern of hospital admissions for dental treatment during primary dentition among children with clefts. Cohort study based on Hospital Episode Statistics, an administrative database of all admissions to National Health Service hospitals in England. Patients born alive between 1997 and 2003 who had both a cleft diagnosis and cleft repair were included. The number of hospital admissions for surgical removal of teeth, simple extraction of teeth, and restoration of teeth before the age of seven was examined. Eight hundred and fifty-eight hospital admissions for dental treatment among 6551 children (<7 year) with a cleft were identified. 66.4% of admissions were primarily for caries and 95.6% involved extractions. 11.4% of children had at least one admission for dental treatment. The presence of additional anomalies, having a more severe cleft type, and living in relatively deprived areas increased the risk of hospital admission. Factors increasing the risk of hospital admission among cleft children should be taken into account when planning services. Efforts to reduce the number of hospital admissions should be focused on disease prevention, particularly among those most at risk of caries. © 2013 BSPD, IAPD and John Wiley & Sons A/S.

    Objective Inaccurate medication history at admission to hospitals leads to preventable adverse drug events, which in turn increase mortality, morbidity, and health care costs. The objective of this study was to investigate the role of pharmacists in identifying discrepancies in medication histories at admission to a tertiary referral hospital in Saudi Arabia. Methods We performed a prospective observational study in a 1200 bed tertiary hospital in Riyadh, Saudi Arabia. Patients were included if they were aged 16 years or older, were taking 5 or more medications, and were able to communicate or were accompanied by a caregiver who could communicate. Over 2 months in 2009, a pharmacist interviewed patients to ascertain all medications used prior to hospitalization, then all discrepancies were discussed with the admitting physician and unintended discrepancies were reported as errors. Results A pharmacist interviewed 60 patients who were taking 564 medications total. Of these patients, 65% were male, and their mean age was 62. Patients were taking an average of 9.4 medications. Twenty-two (37%) patients had at least one discrepancy, with the most common being omissions of medications (35%) and dosage errors (35%). The mean age for patients with discrepancies was 64.6 years, and without discrepancies, 60.8 years (P = 0.37). Conclusion Inaccurate medication history at admission to a hospital was common in Saudi Arabia. This has the potential to cause harm to patients if it remains undetected. Pharmacists could potentially play a major role in obtaining this medication history at the time of hospital admission. PMID:23960767

    A ban on smoking in the workplace was introduced in Ireland on March 29, 2004. As exposure to secondhand smoke has been implicated in the development of coronary disease, this might impact the incidence of acute coronary syndromes (ACS). The smoking ban was associated with a decreased rate of hospital admissions for ACS. We analyzed data collected in a registry of all patients admitted to hospital with ACS in the southwest of Ireland, catchment population 620 525, from March 2003 until March 2007. In the year following implementation of the ban, there was a significant 12% reduction in ACS admissions (177.9 vs 205.9/100,000; 95% confidence interval [CI]: 164.0-185.1, P = 0.002). This reduction was due to fewer events occurring among men (281.5 vs 233.5, P = 0.0011) and current smokers (408 vs 302 admissions, P < 0.0001). There was no change in the rate of admissions for ACS in the following year (174.3/100,000; 95% CI: 164.0-185.1, P > 0.1). However, a further 13% reduction was observed between March 2006 and March 2007 (149.2; 95% CI: 139.7-159.2). Variation in admissions with time as a continuous variable also demonstrated a reduction on implementation of the smoking ban. A national ban on smoking in public places was associated with an early significant decrease in hospital admissions for ACS, suggesting a rapid effect of banning smoking in public places on ACS. A further reduction of similar magnitude 2 years after implementation of the ban is consistent with a longer-term effect that should be further examined in long-term studies. © 2012 Wiley Periodicals, Inc.

    AUDIPOC is a nationwide clinical audit that describes the characteristics, interventions and outcomes of patients admitted to Spanish hospitals because of an exacerbation of chronic obstructive pulmonary disease (ECOPD), assessing the compliance of these parameters with current international guidelines. The present study describes hospital resources, hospital factors related to case recruitment variability, patients' characteristics, and adherence to guidelines. An organisational database was completed by all participant hospitals recording resources and organisation. Over an 8-week period 11,564 consecutive ECOPD admissions to 129 Spanish hospitals covering 70% of the Spanish population were prospectively identified. At hospital discharge, 5,178 patients (45% of eligible) were finally included, and thus constituted the audited population. Audited patients were reassessed 90 days after admission for survival and readmission rates. A wide variability was observed in relation to most variables, hospital adherence to guidelines, and readmissions and death. Median inpatient mortality was 5% (across-hospital range 0-35%). Among discharged patients, 37% required readmission (0-62%) and 6.5% died (0-35%). The overall mortality rate was 11.6% (0-50%). Hospital size and complexity and aspects related to hospital COPD awareness were significantly associated with case recruitment. Clinical management most often complied with diagnosis and treatment recommendations but rarely (<50%) addressed guidance on healthy life-styles. The AUDIPOC study highlights the large across-hospital variability in resources and organization of hospitals, patient characteristics, process of care, and outcomes. The study also identifies resources and organizational characteristics associated with the admission of COPD cases, as well as aspects of daily clinical care amenable to improvement.

    Vitamin deficiency is believed to be common in critical illness. Water soluble and antioxidant vitamins are those most frequently used for supplementation in these patients. There are no data to confirm the prevalence of vitamin deficiencies in high-risk emergently admitted intensive care patients, nor their association with hospital mortality. One hundred and twenty-nine consecutive, critically ill patients who were emergently admitted to intensive care were enrolled in this prospective observational cohort study. Patient data including diagnosis, source of admission and severity of illness scores were prospectively collected. Within the first 48 hours of admission, concentrations of C-reactive protein, Vitamins A, E, B1, B12 and folate were measured on arterial blood. Multivariate stepwise logistic regression modelling was performed to examine the association of vitamin concentrations with hospital mortality. Fifty-five patients (43%) had a biochemical deficiency of one of the five vitamins on admission to the intensive care unit. A total of 18 patients died (14%) during their hospital stay (15 of those in the intensive care unit). Moderate correlations with C-reactive protein concentrations were demonstrated for Vitamins B12, A and E (Spearman's r = 0.309, -0.541 and -0.299, P = 0.001, 0.001 and 0.007 respectively). Hospital mortality was significantly associated with age, APACHE II score, admission and maximum Sequential Organ Failure Assessment scores and admission source in the univariate analyses. Multivariate analysis did not demonstrate an association between biochemical deficiency and mortality. Biochemical deficiencies of water-soluble and antioxidant vitamins are common on admission in unplanned or emergency admissions to the intensive care unit, but we could not demonstrate an independent association with hospital mortality.

    Health care services show epidemiological changes and an increase in the number of consultations due to mental causes and violence without having the necessary capacity to respond to this increasing demand. To analyze and compare the demand for hospitalization due to psychosocial causes in a pediatric hospital during three different periods. Descriptive, retrospective study. The cases were children/adolescents hospitalized for psychosocial causes at Hospital de Niños de la Santísima Trinidad, Córdoba. The data were processed using frequency analysis and chi-square test. 221 records were analyzed. The hospitalization rate was 0.73% in the year 2000, 1.44% in 2005 and 1.26% in 2010. The hospitalization rate for psychosocial causes increased from 0.06 in 2000 to 0.10 in the years 2005 and 2010. The most common reasons for admission were: suspected child abuse in 44.2% (p < 0.0001), suicidal behavior in 18.7%, suspected sexual abuse in 10.05% and substance abuse in 6.8%. The psychomotor agitation episode and psychotic episode showed a prevalence of 2.4% in 2000, while in 2010 it was of 9.5% for the psychomotor agitation episode and of 5.7% for the psychotic episode. Suicidal behavior and suspected sexual abuse were more common in women and the psychomotor agitation episode and substance abuse were more common in men. Hospitalizations for psychosocial causes and, particularly, mental causes in children/adolescents have increased and show a different behavior according to age and gender. Health problems related to violence were the most frequent ones. Sociedad Argentina de Pediatría.

    School dropout is an important predictor of poor health and of high relevance for public health (in accord with the 'causation hypothesis'). Rather than examining how dropout affects health, we set out to examine how poor health might affect school dropout (in accord with the 'selection hypothesis'). Hospital admissions are potentially indicative of more serious disease and might be expected to result in learning backlogs. Longitudinal data of the Dutch Secondary Education Pupil Cohort 1993 (VOCL'93) and the National Medical Registration (LMR) were combined. The study population consisted of 16,239 pupils who were followed from first grade at secondary school until they left fulltime education. Pupils were monitored regarding both their educational careers and their hospital admissions. Nine percent had a hospital admission and 10% became a school dropout. Hospital admissions were only predictive of later school dropout for pupils starting in the highest type of secondary education (pre-university education) [OR 1.54 (95% CI 1.05-2.26)], not for pupils with lower educational levels. Pre-university pupils who had been hospitalized for more than 9 days [OR 2.34 (95% CI 1.08-5.09)] or who were hospitalized more than three times [OR 4.20 (95% CI 1.75-10.04)] had particularly heightened odds of school dropout. Our findings further support the 'selection hypothesis' and confirm the relevance of dropout for public health. Public health workers and educational professionals should probably aim at intensified monitoring of children who have been hospitalized and simultaneously aim at improving accessibility to (higher quality) education in the hospital.

    Numerous studies have reported that admission rates in patients with affective disorders are subject to seasonal variation. Notwithstanding, there has been limited evaluation of the degree to which changeable daily meteorological patterns influence affective disorder admission rates. A handful of small studies have alluded to a potential link between psychiatric admission rates and meteorological variables such as environmental temperature (heat waves in particular), wind direction and sunshine. We used the Kruskal-Wallis test, ARIMA and time-series regression analyses to examine whether daily meteorological variables—namely wind speed and direction, barometric pressure, rainfall, hours of sunshine, sunlight radiation and temperature—influence admission rates for mania and depression across 12 regions in Ireland over a 31-year period. Although we found some very weak but interesting trends for barometric pressure in relation to mania admissions, daily meteorological patterns did not appear to affect hospital admissions overall for mania or depression. Our results do not support the small number of papers to date that suggest a link between daily meteorological variables and affective disorder admissions. Further study is needed.

    Respiratory syncytial virus (RSV) is a leading cause of hospital admission in young children. With several RSV vaccines candidates undergoing clinical trials, recent estimates of RSV burden are required to provide a baseline for vaccine impact studies. To estimate the number of RSV-associated hospital admissions in children aged <5 years in England over a 5-year period from 2007 using ecological time series modelling of national hospital administrative data. Multiple linear regression modelling of weekly time series of laboratory surveillance data and Hospital Episode Statistics (HES) data was used to estimate the number of hospital admissions due to major respiratory pathogens including RSV in children <5 years of age in England from mid-2007 to mid-2012, stratified by age group (<6 months, 6-11 months, 1-4 years) and primary diagnosis: bronchiolitis, pneumonia, unspecified lower respiratory tract infection (LRTI), bronchitis and upper respiratory tract infection (URTI). On average, 33 561 (95% confidence interval 30 429-38 489) RSV-associated hospital admissions in children <5 years of age occurred annually from 2007 to 2012. Average annual admission rates were 35.1 (95% CI: 32.9-38.9) per 1000 children aged <1 year and 5.31 (95% CI: 4.5-6.6) per 1000 children aged 1-4 years. About 84% (95% CI: 81-91%) of RSV-associated admissions were for LRTI. The diagnosis-specific burden of RSV-associated admissions differed significantly by age group. RSV remains a significant cause of hospital admissions in young children in England. Individual-level analysis of RSV-associated admissions is required to fully describe the burden by age and risk group and identify optimal prevention strategies. © 2017 The Authors.

  1. Effect of reclassification of cannabis on hospital admissions for cannabis psychosis: a time series analysis.

    2014-01-01

    The UK Misuse of Drugs Act (1971) divided controlled drugs into three groups A, B and C, with descending criminal sanctions attached to each class. Cannabis was originally assigned by the Act to Group B but in 2004, it was transferred to the lowest risk group, Group C. Then in 2009, on the basis of increasing concerns about a link between high strength cannabis and schizophrenia, it was moved back to Group B. The aim of this study is to test the assumption that changes in classification lead to changes in levels of psychosis. In particular, it explores whether the two changes in 2004 and 2009 were associated with changes in the numbers of people admitted for cannabis psychosis. An interrupted time series was used to investigate the relationship between the two changes in cannabis classification and their impact on hospital admissions for cannabis psychosis. Reflecting the two policy changes, two interruptions to the time series were made. Hospital Episode Statistics admissions data was analysed covering the period 1999 through to 2010. There was a significantly increasing trend in cannabis psychosis admissions from 1999 to 2004. However, following the reclassification of cannabis from B to C in 2004, there was a significant change in the trend such that cannabis psychosis admissions declined to 2009. Following the second reclassification of cannabis back to class B in 2009, there was a significant change to increasing admissions. This study shows a statistical association between the reclassification of cannabis and hospital admissions for cannabis psychosis in the opposite direction to that predicted by the presumed relationship between the two. However, the reasons for this statistical association are unclear. It is unlikely to be due to changes in cannabis use over this period. Other possible explanations include changes in policing and systemic changes in mental health services unrelated to classification decisions. Copyright © 2013 Elsevier B.V. All rights

    Background Adverse Drug Reactions (ADRs) have been regarded as a major public health problem since they represent a sizable percentage of admissions. Unfortunately, there is a wide variation of ADR related admissions among different studies. The aim of this study was to evaluate the frequency of ADR related admissions and its dependency on reporting and method of detection, urgency of admissions and included medical departments reflecting department/hospital type within one study. Methods The study team of internal medicine specialists retrospectively reviewed 520 randomly selected medical records (3%) of patients treated in the medical departments of the primary city and tertiary referral governmental hospital for certain ADRs causing admissions regarding WHO causality criteria. All medical records were checked for whether the treating physicians recognised and documented ADRs causing admissions. The hospital information system was checked to ensure ADR related diagnoses were properly coded and the database of a national spontaneous reporting system was searched for patients with ADRs included in this study. Results The established frequency of admissions due to certain ADRs recognised by the study team and documented in medical records by the treating physicians was the same and represented 5.8% of all patients (30/520). The frequency of ADR causing admissions detected by employing a computer-assisted approach using an ICD-10 coding system was 0.2% (1/520), and no patient admitted due to ADRs was reported to the national reporting system (0/520). The recognized frequency of ADR related admissions also depends on the department's specialty (p = 0.001) and acceptance of urgently admitted patients (p = 0.001). Patients admitted due to ADRs were significantly older compared to patients without ADRs (p = 0.025). Gastrointestinal bleeding due to NSAID, acetylsalicylic acid and warfarin was the most common ADR that resulted in admission and represented 40% of all

    Background The Global Influenza Hospital Surveillance Network was established in 2012 to obtain valid epidemiologic data on hospital admissions with influenza-like illness. Here we describe the epidemiology of admissions with influenza within the Northern Hemisphere sites during the 2013/2014 influenza season, identify risk factors for severe outcomes and complications, and assess the impact of different influenza viruses on clinically relevant outcomes in at-risk populations. Methods Eligible consecutive admissions were screened for inclusion at 19 hospitals in Russia, Turkey, China, and Spain using a prospective, active surveillance approach. Patients that fulfilled a common case definition were enrolled and epidemiological data were collected. Risk factors for hospitalization with laboratory-confirmed influenza were identified by multivariable logistic regression. Findings 5303 of 9507 consecutive admissions were included in the analysis. Of these, 1086 were influenza positive (534 A(H3N2), 362 A(H1N1), 130 B/Yamagata lineage, 3 B/Victoria lineage, 40 untyped A, and 18 untyped B). The risk of hospitalization with influenza (adjusted odds ratio [95% confidence interval]) was elevated for patients with cardiovascular disease (1.63 [1.33–2.02]), asthma (2.25 [1.67–3.03]), immunosuppression (2.25 [1.23–4.11]), renal disease (2.11 [1.48–3.01]), liver disease (1.94 [1.18–3.19], autoimmune disease (2.97 [1.58–5.59]), and pregnancy (3.84 [2.48–5.94]). Patients without comorbidities accounted for 60% of admissions with influenza. The need for intensive care or in-hospital death was not significantly different between patients with or without influenza. Influenza vaccination was associated with a lower risk of confirmed influenza (adjusted odds ratio = 0.61 [0.48–0.77]). Conclusions Influenza infection was detected among hospital admissions with and without known risk factors. Pregnancy and underlying comorbidity increased the risk of detecting influenza

    OBJECTIVE: To investigate short term effects of concentrations of pollutants in ambient air on hospital admissions for cardiovascular and respiratory diseases in Hong Kong. METHODS: Retrospective ecological study. A Poisson regression was performed of concentrations of daily air pollutant on daily counts of emergency hospital admissions in 12 major hospitals. The effects of time trend, season, and other cyclical factors, temperature, and humidity were accounted for. Autocorrelation and overdispersion were corrected. Daily concentrations of nitrogen dioxide (NO2), sulphur dioxide (SO2), ozone (O3), and particulate matter < 10 microns in aerodynamic diameter (PM10) were obtained from seven air monitoring stations in Hong Kong in 1994 and 1995. Relative risks (RR) of respiratory and cardiovascular disease admissions (for an increase of 10 micrograms/m3 in concentration of air pollutant) were calculated. RESULTS: Significant associations were found between hospital admissions for all respiratory diseases, all cardiovascular diseases, chronic obstructive pulmonary diseases, and heart failure and the concentrations of all four pollutants. Admissions for asthma, pneumonia, and influenza were significantly associated with NO2, O3, and PM10. Relative risk (RR) for admissions for respiratory disease for the four pollutants ranged from 1.013 (for SO2) to 1.022 (for O3), and for admissions for cardiovascular disease, from 1.006 (for PM10) to 1.016 (for SO2). Those aged > or = 65 years were at higher risk. Significant positive interactions were detected between NO2, O3, and PM10, and between O3 and winter months. CONCLUSIONS: Adverse health effects are evident at current ambient concentrations of air pollutants. Further reduction in air pollution is necessary to protect the health of the community, especially that of the high risk group.   PMID:10658547

    Introduction The last few years have witnessed rapid scaling-up of key malaria interventions in several African countries following increases in development assistance. However, there is only limited country-specific information on the health impact of expanded coverage of these interventions. Methods Paediatric admission data were assembled from 4 hospitals in Malawi reflecting different malaria ecologies. Trends in monthly clinical malaria admissions between January 2000 and December 2010 were analysed using time-series models controlling for covariates related to climate and service use to establish whether changes in admissions can be related to expanded coverage of interventions aimed at reducing malaria infection. Results In 3 of 4 sites there was an increase in clinical malaria admission rates. Results from time series models indicate a significant month-to-month increase in the mean clinical malaria admission rates at two hospitals (trend P<0.05). At these hospitals clinical malaria admissions had increased from 2000 by 41% to 100%. Comparison of changes in malaria risk and ITN coverage appear to correspond to a lack of disease declines over the period. Changes in intervention coverage within hospital catchments showed minimal increases in ITN coverage from <6% across all sites in 2000 to maximum of 33% at one hospital site by 2010. Additionally, malaria transmission intensity remained unchanged between 2000–2010 across all sites. Discussion Despite modest increases in coverage of measures to reduce infection there has been minimal changes in paediatric clinical malaria cases in four hospitals in Malawi.

    Backgrounds AUDIPOC is a nationwide clinical audit that describes the characteristics, interventions and outcomes of patients admitted to Spanish hospitals because of an exacerbation of chronic obstructive pulmonary disease (ECOPD), assessing the compliance of these parameters with current international guidelines. The present study describes hospital resources, hospital factors related to case recruitment variability, patients’ characteristics, and adherence to guidelines. Methodology/Principal Findings An organisational database was completed by all participant hospitals recording resources and organisation. Over an 8-week period 11,564 consecutive ECOPD admissions to 129 Spanish hospitals covering 70% of the Spanish population were prospectively identified. At hospital discharge, 5,178 patients (45% of eligible) were finally included, and thus constituted the audited population. Audited patients were reassessed 90 days after admission for survival and readmission rates. A wide variability was observed in relation to most variables, hospital adherence to guidelines, and readmissions and death. Median inpatient mortality was 5% (across-hospital range 0–35%). Among discharged patients, 37% required readmission (0–62%) and 6.5% died (0–35%). The overall mortality rate was 11.6% (0–50%). Hospital size and complexity and aspects related to hospital COPD awareness were significantly associated with case recruitment. Clinical management most often complied with diagnosis and treatment recommendations but rarely (<50%) addressed guidance on healthy life-styles. Conclusions/Significance The AUDIPOC study highlights the large across-hospital variability in resources and organization of hospitals, patient characteristics, process of care, and outcomes. The study also identifies resources and organizational characteristics associated with the admission of COPD cases, as well as aspects of daily clinical care amenable to improvement. PMID:22911875

    Relevant patient information is frequently difficult to obtain in emergency department (ED) visits. Improved provider access to previously inaccessible patient information may improve the quality of care and reduce hospital admissions. Health information exchange (HIE) systems enable access to longitudinal, community-wide patient information at the point of care. However, the ability of HIE to avert admissions is not well demonstrated. We sought to determine if HIE system usage is correlated with a reduction in admissions via the ED. We identified 15,645 adults from New York State with an ED visit during a 6-month period, all of whom consented to have their information accessible in the HIE system, and were continuously enrolled in two area health plans. Using claims we determined if the ED encounter resulted in an admission. We used the HIE's system log files to determine usage during the encounter. We determined the association between HIE system use and the likelihood of admission to the hospital from the ED and potential cost savings. The HIE system was accessed during 2.4% of encounters. The odds of an admission were 30% lower when the system was accessed after controlling for confounding (odds ratio = 0.70; 95%C I= 0.52, 0.95). The annual savings in the sample was $357,000. These findings suggest that the use of an HIE system may reduce hospitalizations from the ED with resultant cost savings. This is an important outcome given the substantial financial investment in interventions designed to improve provider access to patient information in the US.

    BACKGROUND: Asthma exacerbations constitute one of the most common causes of emergency department (ED) attendance in most developed countries. While severe asthma often requires hospitalization, variability in admission practices has been observed. OBJECTIVE: To describe the factors associated with admission to Canadian hospitals for acute asthma after ED treatment. METHODS: Subjects 18 to 55 years of age treated for acute asthma in 20 Canadian EDs prospectively underwent a structured ED interview (n=695) and telephone interview two weeks later. RESULTS: The median age of the patients was 30 years, and the majority were women (62.8%). The admission rate was 13.1% (95% CI 10.7% to 15.8%). Admitted patients were older, more often receiving oral or inhaled corticosteroids at presentation, and more frequently receiving systemic corticosteroids and magnesium sulphate in the ED. Similar proportions received beta-2 agonists and/or ipratropium bromide within 1 h of arrival. On multivariable analyses, factors associated with admission included age, previous admission in the past two years, more than eight beta-2 agonist puffs in the past 24 h, a Canadian Triage and Acuity Score of 1 to 2, a respiratory rate of greater than 22 breaths/min and an oxygen saturation of less than 95%. CONCLUSION: The admission rate for acute asthma from these Canadian EDs was lower than reported in other North American studies. The present study provides insight into practical factors associated with admission for acute asthma and highlights the importance of history and asthma severity markers on ED decision making. Further efforts to standardize ED management and expedite admission decision-making appear warranted. PMID:20186368

    The present work analyzed the association between hospital costs and patient admission characteristics in a general public hospital in the city of Rio de Janeiro, Brazil. The unit costs method was used to estimate inpatient day costs associated to specific hospital clinics. With this aim, three "cost centers" were defined in order to group direct and indirect expenses pertaining to the clinics. After the costs were estimated, a standard linear regression model was developed for correlating cost units and their putative predictors (the patients gender and age, the admission type (urgency/elective), ICU admission (yes/no), blood transfusion (yes/no), the admission outcome (death/no death), the complexity of the medical procedures performed, and a risk-adjustment index). Data were collected for 3100 patients, January 2001-January 2003. Average inpatient costs across clinics ranged from (US$) 1135 [Orthopedics] to 3101 [Cardiology]. Costs increased according to increases in the risk-adjustment index in all clinics, and the index was statistically significant in all clinics except Urology, General surgery, and Clinical medicine. The occupation rate was inversely correlated to costs, and age had no association with costs. The (adjusted) per cent of explained variance varied between 36.3% [Clinical medicine] and 55.1% [Thoracic surgery clinic]. The estimates are an important step towards the standardization of hospital costs calculation, especially for countries that lack formal hospital accounting systems.

    Background Stimulated by the WHO Framework Convention on Tobacco Control, many countries in Latin America adopted comprehensive smoke-free policies. In March 2006, Uruguay became the first Latin American country to adopt 100% smoke-free national legislation, which ended smoking in all indoor public places and workplaces, including restaurants and bars. The objective of this study was to evaluate trends in hospital admissions for cardiovascular disease 2 years before and 2 years after the policy was implemented in Uruguay. Methods Reports of hospital admissions for acute myocardial infarction (AMI) (International Classification of Disease-10 I21) from 37 hospitals (79% of all hospital admissions in the country), representing the period 2 years before and 2 years after the adoption of a nationwide smoke-free policy in Uruguay (between 1 March 2004 and 29 February 2008), were reviewed. A time series analysis was undertaken to compare the average monthly number of events of hospital admission for AMI before and after the smoke-free law. Results A total of 7949 hospital admissions for AMI were identified during the 4-year study period. Two years after the smoke-free policy was enacted, hospital admissions for AMI fell by 22%. The same pattern and roughly the same magnitude of reduction in AMI admissions were observed for patients seen in public and private hospitals, men, women and people aged 40–65 years and older than 65 years. Conclusions The national smoke-free policy implemented in Uruguay in 2006 was associated with a significant reduction in hospital admissions for AMI. PMID:22337557

    Increased morbidity and mortality have been associated with extreme heat events, particularly in temperate climates. Few epidemiologic studies have considered the impact of extreme heat events on hospitalization rates in the Pacific Northwest region. This study quantifies the historical (May to September 1990-2010) heat-morbidity relationship in the most populous Pacific Northwest County -King County, Washington. A relative risk (RR) analysis was used to explore the association between heat and all non-traumatic hospitalizations on 99th percentile heat days, while a time series analysis using a piece-wise linear model approximation was used to estimate the effect that heat’s intensity has on hospitalizations, adjusted for temporal trends and day of the week. A non-statistically significant 2% [95% CI: 1.02 (0.98, 1.05)] increase in hospitalization risk, on a heat day versus a non-heat day, was noted for all-ages, all non-traumatic causes. When considering the effect heat intensity has on admissions, we found a statistically significant 1.59% (95% CI: 0.9%, 2.29%) increase in admissions per degree increase in humidex above 37.4 °C. Admissions stratified by cause and age produced statistically significant results with both relative risk and time series analyses for nephritis and nephrotic syndromes, acute renal failure and natural heat exposure hospitalizations. This study demonstrates that heat, expressed as humidex, is associated with increased hospital admissions. When stratified by age and cause of admission, the non-elderly (less than 85) age groups experience significant risk for: nephritis and nephrotic syndromes, acute renal failure, natural heat exposure, COPD and asthma hospitalizations.

    Background: Heat-wave frequency, intensity, and duration are increasing with global climate change. The association between heat and mortality in the elderly is well documented, but less is known regarding associations with hospital admissions. Objectives: Our goal was to determine associations between moderate and extreme heat, heat waves, and hospital admissions for nonaccidental causes among Medicare beneficiaries ≥ 65 years of age in 114 cities across five U.S. climate zones. Methods: We used Medicare inpatient billing records and city-specific data on temperature, humidity, and ozone from 1992 through 2006 in a time-stratified case-crossover design to estimate the association between hospitalization and moderate [90th percentile of apparent temperature (AT)] and extreme (99th percentile of AT) heat and heat waves (AT above the 95th percentile over 2–8 days). In sensitivity analyses, we additionally considered confounding by ozone and holidays, different temperature metrics, and alternate models of the exposure–response relationship. Results: Associations between moderate heat and hospital admissions were minimal, but extreme heat was associated with a 3% (95% CI: 2%, 4%) increase in all-cause hospital admissions over the subsequent 8 days. In cause-specific analyses, extreme heat was associated with increased hospitalizations for renal (15%; 95% CI: 9%, 21%) and respiratory (4%; 95% CI: 2%, 7%) diseases, but not for cardiovascular diseases. An added heat-wave effect was observed for renal and respiratory admissions. Conclusion: Extreme heat is associated with increased hospital admissions, particularly for renal causes, among the elderly in the United States.

    Sickle cell disease is an increasing global health burden. This inherited disease is characterized by a remarkable phenotypic heterogeneity, which can only partly be explained by genetic factors. Environmental factors are likely to play an important role but studies of their impact on disease severity are limited and their results are often inconsistent. This study investigated associations between a range of environmental factors and hospital admissions of young patients with sickle cell disease in London and in Paris between 2008 and 2012. Specific analyses were conducted for subgroups of patients with different genotypes and for the main reasons for admissions. Generalized additive models and distributed lag non-linear models were used to assess the magnitude of the associations and to calculate relative risks. Some environmental factors significantly influence the numbers of hospital admissions of children with sickle cell disease, although the associations identified are complicated. Our study suggests that meteorological factors are more likely to be associated with hospital admissions for sickle cell disease than air pollutants. It confirms previous reports of risks associated with wind speed (risk ratio: 1.06/standard deviation; 95% confidence interval: 1.00–1.12) and also with rainfall (1.06/standard deviation; 95% confidence interval: 1.01–1.12). Maximum atmospheric pressure was found to be a protective factor (0.93/standard deviation; 95% confidence interval: 0.88–0.99). Weak or no associations were found with temperature. Divergent associations were identified for different genotypes or reasons for admissions, which could partly explain the lack of consistency in earlier studies. Advice to patients with sickle cell disease usually includes avoiding a range of environmental conditions that are believed to trigger acute complications, including extreme temperatures and high altitudes.

    This study was the first to explore the relationship between Asian dust storm events (ADS) and acute myocardial infarction (AMI) hospital admissions by applying time series models. Nationwide population-based hospitalization claims data in Taiwan were used. There were 143,063 AMI admissions during 2000-2009. An autoregressive with exogenous variables (ARX) time series model was used to investigate the dynamic connection between AMI hospital admissions and ADS events. AMI hospitalizations significantly spiked on post-ADS day three. Among the total population, 3.2 more cases of AMI admissions occurred on post-ADS day three. When the data were stratified by age and gender, the same delayed effect was present in the male population, especially those aged 45-64 and over 74. Our study shows that although an ADS event does not cause an immediate incidence of AMI, storms may increase AMI incidence through a delayed effect. Hence, AMI prevention is not only important during a dust storm, but particularly so in subsequent days. During the days after an ADS, exposure to dust should be minimized by staying indoors as much as possible and by wearing a mask when exposure to dust is unavoidable. This is especially true for working and older adults. Nurses at local public health centers can increase awareness and promote public safety by providing health information to local communities regarding the link between dust storms and AMI. © 2015 Wiley Periodicals, Inc.

    OBJECTIVES: To quantify the proportion of potentially avoidable emergency short term admissions to hospital and to identify ways in which they could have been avoided. DESIGN: Confidential enquiry by peer review group. SETTING: St Mary's Hospital, Newport, Isle of Wight. SUBJECTS: All emergency, short term admissions (discharged home within five days) to medicine, general surgery, orthopaedics, gynaecology, ENT, and ophthalmology specialties for 28 (24 hour) days over a six month period in 1994. MAIN OUTCOME MEASURES: Appropriateness of admissions decided by the peer group, the peer group's opinion of ideal management, and the patients' views on the appropriateness of their admission. RESULTS: Altogether 139 cases satisfied the inclusion criteria. Complete data were collected on 123 cases and the peer group considered 81 in the time available. Twenty one of the 81 cases were judged "potentially avoidable". These represent 9.5% (95% CI 6.3%, 13.5%) of short term admissions to the specialties studied. The peer group considered that seven of 10 patients referred by a general practitioner (GP) could have been managed by the GP alone and that the remaining three had been referred appropriately but need not have been admitted had a consultant opinion been available in the accident and emergency (A&E) department. Two of the 10 would have required home support to avoid hospital admission. Five of 11 patients who referred themselves to A&E could have been discharged home without admission and without recourse to a specialist opinion. The remaining six could have been discharged had a consultant opinion been available in A&E. CONCLUSIONS: Urgent consultant opinion, either in A&E or in an outpatient clinic, would have prevented most of these inappropriate admissions, and home support would have expedited the ability to discharge some patients. Further research into the costs and benefits of methods for providing these services is needed urgently. PMID:9328544

    The paper provides a review of one year of military Mental Health (MH) hospital admissions. This includes an exploration into demographic trends, differences in clinical opinion and how information gained is used to improve the service and ensure appropriate, cost effective care in the optimum environment. The sample group is entitled military MH hospital admissions from 1 April 2005 to 31 March 2006. Data was collected on questionnaires with SPSS used for the management and analysis of the quantitative data, with the information exposed to descriptive and inferential statistical analysis. There were 344 admissions. The paper contains a detailed review of a number of variables. Depression was the most common diagnosis resulting in 112 (33%) hospital admissions and Post Traumatic Stress Disorder accounted for 23 (7%). There were statistically significant differences that may be attributable to gender with more women admitted with depression and more men with alcohol related disorders. The average length of stay was 21 days, with 48% of patients discharged within 3 weeks. 45% of all returns included significant events reporting that highlighted written evidence of good and poor practice. This study is part of an extensive monitoring programme of military MH hospital admissions. Depression is the most common MH problem leading to hospital admission. The results indicate that Service-personnel have access to a highly responsive service that provides brief assessment and treatment within a safe therapeutic environment. 45% of returns included significant event information that resulted in policy changes, leading to improved patient care and a better interface with the NHS. Bench-marking, both internally between military Departments of Community Mental Health and externally have improved visibility and self awareness leading to better GP induction programmes, PHC educational seminars and the establishment of MH web-pages.

    This study aimed to evaluate the weekday and weekend distribution of stroke case hospital admissions and their respective prognosis based on a sample from the Estudo de Mortalidade e Morbidade do Acidente Vascular Cerebral (EMMA), a cohort of stroke patients admitted to a community hospital in the city of São Paulo, Brazil. We ascertained all consecutive cases of first-time strokes between April 2006 and December 2008 and performed a subsequent one-year follow-up. No association was found between frequency of hospital admissions due to ischemic and hemorrhagic strokes and the specific day of the week on which the admission occurred. However, ten-day and twelve-month case-fatality was higher in hemorrhagic stroke patients admitted at the weekend. We also found that intracerebral hemorrhage patients admitted on weekends had a worse survival rate (50%) compared with those admitted during weekdays (25.6%, P log-rank = 0.03). We found a multivariate hazard ratio of 2.49 (95%CI: 1.10-5.81, P trend = 0.03) for risk of death at the weekend compared to weekdays for intracerebral hemorrhage cases. No difference in survival was observed with respect to the overall sample of stroke or ischemic stroke patients.

    Reports of hospitalized systemic connective tissue disorders (SCNTD) are mostly disease-specific reports from institutional databases. To clarify the admission rate, disease determination, hospital mortality rate, length of stay and hospital charges among hospitalized patients diagnosed with SCNTD. The data were extracted from the 2010 national database of hospitalized patients provided by the Thai Health Coding Center, Bureau of Policy and Strategy, Ministry of Public Health, Thailand. Patients over 18 years having International Classification of Diseases (ICD)-10 codes for a primary diagnosis related to SCNTD were included. There were 6861 admissions coded as disorders related to SCNTD during the fiscal year 2010. The admission rate was 141 per 100,000 admissions. Among these, systemic lupus erythematosus (SLE) was the most common, followed by systemic sclerosis (SSc) and dermatomyositis/polymyositis (DM-PM). The overall mean length of hospital stay was 6.8 days. Small vessel vasculitis and Sjögren syndrome had the longest and the shortest hospital stays respectively (14.5 vs. 5.3 days). Hospital charges were highest among systemic vasculitis and DM-PM patients. The admission rate for SCNTD in Thailand was 141 per 100,000 admissions among which SLE was the most common. Overall hospital mortality was 4.1%. Although a lower prevalence was found among systemic vasculitis, it had a higher mortality rate, longer length of stay and greater therapeutic cost. © 2013 The Authors International Journal of Rheumatic Diseases © 2013 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

Air pollutants and dust storm increase risk of morbidity, for cardiovascular and respiratory diseases, and increase the number of deaths. The city of Ahvaz is considered as the focal point of air pollution and dust storm in Iran. The aim of this study was to determine the number of Hospital Admission Respiratory Disease (HARD) including asthma attacks, acute bronchitis and chronic obstructive pulmonary disease attributed to PM 10 by a descriptive study during normal and dust event days in Ahvaz during the time period 2010-2012. The hourly PM 10 data was collected from the Iranian Environmental Protection Agency and Razi hospital. The annual PM 10 mean concentrations reached 282, 288 and 278 μg/m 3 in 2010, 2011 and 2012, respectively. The number of HARD attributed to PM 10 was 1438, 1945 and 1393 people, respectively, and the highest number of daily admissions was attributed to the highest daily PM 10 concentration in Ahvaz. The average number of daily HARD during dusty days was higher than normal days, and a significant positive correlation, between the number of hospital admissions and dusty days, was found. Dust had significant impact on HARD in Ahvaz.

    To evaluate the impact of 2 smoking bans enacted in 2006 (partial ban) and 2011 (comprehensive ban) on hospitalizations for cardiovascular disease in the Spanish adult population. The study was performed in 14 provinces in Spain. Hospital admission records were collected for acute myocardial infarction (AMI), ischemic heart disease (IHD), and cerebrovascular disease (CVD) in patients aged ≥ 18 years from 2003 through 2012. We estimated immediate and 1-year effects with segmented-linear models. The coefficients for each province were combined using random-effects multivariate meta-analysis models. Overall, changes in admission rates immediately following the implementation of the partial ban and 1 year later were -1.8% and +1.2% for AMI, +0.1 and +0.4% for IHD, and +1.0% and +2.8% for CVD (P>.05). After the comprehensive ban, immediate changes were -2.3% for AMI, -2.6% for IHD, and -0.8% for CVD (P>.05), only to return to precomprehensive ban values 1 year later. For patients aged ≥ 65 years of age, immediate changes associated with the comprehensive ban were -5.0%, -3.9%, and -2.3% for AMI, IHD, and CVD, respectively (P<.05). Again, the 1-year changes were not statistically significant. In Spain, smoking bans failed to significantly reduce hospitalizations for AMI, IHD, or CVD among patients ≥ 18 years of age. In the population aged ≥ 65 years, hospital admissions due to these diseases showed significant decreases immediately after the implementation of the comprehensive ban, but these reductions disappeared at the 1-year evaluation.

    Abstract With global climate change, more frequent severe snowstorms are expected; however, evidence regarding their health effects is very limited. We gathered detailed medical records on hospital admissions (n = 433,037 admissions) from the 4 largest hospitals in Boston, Massachusetts, during the winters of 2010–2015. We estimated the percentage increase in hospitalizations for cardiovascular and cold-related diseases, falls, and injuries on the day of and for 6 days after a day with low (0.05–5.0 inches), moderate (5.1–10.0 inches), or high (>10.0 inches) snowfall using distributed lag regression models. We found that cardiovascular disease admissions decreased by 32% on high snowfall days (relative risk (RR) = 0.68, 95% confidence interval (CI): 0.54, 0.85) but increased by 23% 2 days after (RR = 1.23, 95% CI: 1.01, 1.49); cold-related admissions increased by 3.7% on high snowfall days (RR = 3.7, 95% CI: 1.6, 8.6) and remained high for 5 days after; and admissions for falls increased by 18% on average in the 6 days after a moderate snowfall day (RR = 1.18, 95% CI: 1.09, 1.27). We did not find a higher risk of hospitalizations for injuries. To our knowledge, this is the first study in which the time course of hospitalizations during and immediately after snowfall days has been examined. These findings can be translated into interventions that prevent hospitalizations and protect public health during harsh winter conditions. PMID:28137774

    Background Internationally health services are facing increasing demands due to new and more expensive health technologies and treatments, coupled with the needs of an ageing population. Reducing avoidable use of expensive secondary care services, especially high cost admissions where no procedure is carried out, has become a focus for the commissioners of healthcare. Method We set out to identify, evaluate and share learning about interventions to reduce avoidable hospital admission across a regional Academic Health and Social Care Network (AHSN). We conducted a service evaluation identifying initiatives that had taken place across the AHSN. This comprised a literature review, case studies, and two workshops. Results We identified three types of intervention: pre-hospital; within the emergency department (ED); and post-admission evaluation of appropriateness. Pre-hospital interventions included the use of predictive modelling tools (PARR – Patients at risk of readmission and ACG – Adjusted Clinical Groups) sometimes supported by community matrons or virtual wards. GP-advisers and outreach nurses were employed within the ED. The principal post-hoc interventions were the audit of records in primary care or the application of the Appropriateness Evaluation Protocol (AEP) within the admission ward. Overall there was a shortage of independent evaluation and limited evidence that each intervention had an impact on rates of admission. Conclusions Despite the frequency and cost of emergency admission there has been little independent evaluation of interventions to reduce avoidable admission. Commissioners of healthcare should consider interventions at all stages of the admission pathway, including regular audit, to ensure admission thresholds don’t change. PMID:22682525

    Downsizing has in previous studies, as well as in public debate, been associated with increased sickness absence. No studies have, however, looked at the long-term relation between workplace expansion and morbidity. We investigated exposure to personnel change during 1991-96 in relation to long-term (90 days or longer) medically certified sickness absence and hospital admission for specified diagnoses during 1997-99 in 24?036 participants with a complete employment record in the biennial national Swedish Work Environment Surveys from 1989 to the end of 1999. Accumulated exposure to large expansion (> or =18% per year) was related to an increased risk of long-term sickness absence (odds ratio 1.07 [95% CI 1.01-1.13], p=0.013) and hospital admission (1.09 [1.02-1.16], p=0.017). In this context, odds ratio signifies the change in odds for each additional year of exposure, varying from 0 to 6. Moderate expansion (> or =8% and <18% per year), was associated with a decreased risk of admission (0.91 [0.84-0.98], p=0.012). Moderate downsizing (> or =8% and <18% per year) was associated with an increased risk of sickness absence (1.07 [1.02-1.12], p=0.003). The strongest association between large expansion and sickness absence was in women in the public sector (1.18 [1.08-1.30], p=0.0002), corresponding to an odds ratio of 2.77 [1.62-4.74] between full exposure (all 6 years) and no exposure. This study confirms earlier findings that downsizing is associated with health risks. It also shows that repeated exposure to rapid personnel expansion, possibly connected with centralisation of functions, statistically predicts long-term sickness absence and hospital admission. Although no conclusions about causal pathways can be drawn from our results, this exposure should be considered in future studies, policy making, and occupational health care practice.

England and the Oxford Record Linkage Study area. Age- and gender-specific hospital admission rates, and summary age- and sex-standardised rates, for people aged under 25 years per 100,000 population in each age group. Admission rates declined from the 1960s to the early 1970s. For example, the standardised rates were 12.8 (95% confidence interval 11.2-14.5) per 100,000 in England in 1968 and 4.0 (3.0-4.9) per 100,000 in 1973. They then increased to reach 45.0 (41.4-48.6) per 100,000 in 1978 and 47.4 (43.7-51.1) in 1982. From the late 1980s, admission rates continued to decline, falling to between 1 and 4 per 100,000 in each of the years between 2003 and 2011. While the trend in hospital admissions closely followed that in notifications, the annual ratio between these two measures was not consistent ranging from 1.07 (95% confidence interval 1.00-1.14) to 4.03 (3.79-4.27) notifications per admission over the last 10 years. Epidemics of whooping cough in the late 1970s and early 1980s were associated with a significant rise in hospital admission rates. Current admission rates are low, by historical comparison. Vaccine programmes must continue to be fully implemented in order to improve control of pertussis activity.

    Multiple sclerosis (MS) is the most prevalent neurological disease among young adults in Spain. A number of recent studies have linked traffic-related pollution, both chemical and acoustic, to the aetiology and exacerbation of neurodegenerative diseases. To analyse the existence of a significant short-term association between daily emergency MS hospital admissions and chemical and acoustic pollution caused by traffic in Madrid. We conducted a longitudinal ecological time series study, in which the dependent variable was the number of daily emergency MS hospital admissions (ICD-9: 340) registered in Madrid from 1 January 2001 to 31 December 2009. The independent variables were daily mean concentrations (μg/m 3 ) of PM 2.5 , PM 10 , O 3 and NO 2 . Equivalent diurnal (Leqd), nocturnal (Leqn) and daily equivalent noise levels (Leq24) were also considered. In addition, we controlled for linear trends, seasonality and the autoregressive nature of the series itself. Day of the week was also added as a covariate. Significant environmental variables were determined using Poisson GLM models. Relative risk (RR) and attributable risk (AR) values were calculated for increases of 10μg/m 3 in the case of chemical pollutants and 1dB(A) in noise levels. While there was no association between chemical pollutants caused by traffic and MS admissions, such an association was in evidence for Leqd at lag zero. This association is linear without a threshold, with there being a level above 67dB(A) from which this effect is more pronounced. The RRs were as follows: for all Leqd values, 1.21 (95% CI: 1.16, 1.26); and for Leqd >67dB(A), 1.62 (95% CI: 1.24, 2.13). The above results indicate that traffic noise can exacerbate MS symptoms, leading to hospital admissions due to this cause. Copyright © 2017 Elsevier B.V. All rights reserved.

    To explore reasons for increased risk of hospital admission among south Asian patients with asthma. Qualitative interview study using modified critical incident technique and framework analysis. Newham, east London, a deprived area with a large mixed south Asian population. 58 south Asian and white adults with asthma (49 admitted to hospital with asthma, 9 not admitted); 17 general practitioners; 5 accident and emergency doctors; 2 out of hours general practitioners; 1 asthma specialist nurse. Patients' and health professionals' views on influences on admission, events leading to admission, general practices' organisation and asthma strategies, doctor-patient relationship, and cultural attitudes to asthma. South Asian and white patients admitted to hospital coped differently with asthma. South Asians described less confidence in controlling their asthma, were unfamiliar with the concept of preventive medication, and often expressed less confidence in their general practitioner. South Asians managed asthma exacerbations with family advocacy, without systematic changes in prophylaxis, and without systemic corticosteroids. Patients describing difficulty accessing primary care during asthma exacerbations were registered with practices with weak strategies for asthma care and were often south Asian. Patients with easy access described care suggesting partnerships with their general practitioner, had better confidence to control asthma, and were registered with practices with well developed asthma strategies that included policies for avoiding hospital admission. The different ways of coping with asthma exacerbations and accessing care may partly explain the increased risk of hospital admission in south Asian patients. Interventions that increase confidence to control asthma, confidence in the general practitioner, understanding of preventive treatment, and use of systemic corticosteroids in exacerbations may reduce hospital admissions.

    AIM—To estimate the rates of hospital admissions for primary angle closure glaucoma (PACG) in Chinese, Malays, and Indians in Singapore
METHODS—A population-wide hospital discharge database in Singapore was used to identify all hospital admissions with a primary discharge diagnosis of PACG (International Classification of Disease—CM code: 365.2). The Singapore census was used for denominator data.
RESULTS—Between 1993 and 1997 there were 894 hospital admissions for PACG. The mean annual rate of PACG admissions was 11.1 per 100 000 (95% confidence interval (CI), 10.4, 11.8) among people aged 30 years and over. The annual rate was highest for Chinese (age and sex adjusted rate: 12.2 per 100 000), which was twice that of Malays (6.0 per 100 000) and Indians (6.3 per 100 000). Females had two times higher rates than males in all three races (age adjusted relative risk: 2.0, 95% CI: 1.7, 2.3).
CONCLUSION—Malay and Indian people had identical rates of hospital admissions for PACG, which were only half the rates compared with Chinese.

    The objective of this study was to assess the trends in hospitalization for sunburn in Western Australia from 1988 to 2008. De-identified linked hospital morbidity data for all index sunburn admissions in Western Australia for the period 1988 to 2008 were analyzed. Poisson regression analysis was used to estimate trends in hospital admissions. Hospitalizations increased from 1.6 (95% confidence interval [CI] = 1.0-2.2) per 100 000 person years in 1988 to 2.7 (95% CI = 1.9-3.4) per 100 000 person years in 1997, declining thereafter to 1.5 (95% CI = 1.0-2.0) per 100 000 person years in 2008. Increased hospitalizations rates were estimated for adults 25 to 44 years and 65 years or older, with a significant decline estimated for children younger than 5 years; rates remained stable for all other age groups. This study found no significant overall reduction in sunburn hospitalizations over the 20-year study period. raise concerns about the sun-protective behaviors and skin cancer risk of the population in Western Australia.

    Self-harm patient management varies markedly between hospitals, with fourfold differences in the proportion of patients who are admitted to a medical or psychiatric inpatient bed. The current study aimed to investigate whether differences in admission practices are associated with patient outcomes (repeat self-harm) while accounting for differences in patient case mix. Data came from the National Self-Harm Registry Ireland. A prospective cohort of 43,595 self-harm patients presenting to hospital between 2007 and 2012 were included. As well as conventional regression analysis, instrumental variable (IV) methods utilising between hospital differences in rates of hospital admission were used in an attempt to gain unbiased estimates of the association of admission with risk of repeat self-harm. The proportion of self-harm patients admitted to a medical bed varied from 10 to 74 % between hospitals. Conventional regression and IV analysis suggested medical admission was not associated with risk of repeat self-harm. Psychiatric inpatient admission was associated with an increased risk of repeat self-harm in both conventional and IV analyses. This increased risk persisted in analyses stratified by gender and when restricted to self-poisoning patients only. No strong evidence was found to suggest medical admission reduces the risk of repeat self-harm. Models of health service provision that encourage prompt mental health assessment in the emergency department and avoid unnecessary medical admission of self-harm patients appear warranted. Psychiatric inpatient admission may be associated with a heightened risk of repeat self-harm in some patients, but these findings could be biased by residual confounding and require replication.

    Background Whether there is an association between depression at the time of acute myocardial infarction and subsequent risk of cardiac complications and death remains controversial. Most studies of this risk factor have been limited to patients of single institutions, and this might account for the varying results. We prospectively evaluated patients admitted to 5 tertiary care and 5 community hospitals and followed them for 1 year to measure the prevalence and prognostic impact of depressive symptoms after acute myocardial infarction. Methods Patients were recruited for the study by trained nurse interviewers who had documented acute myocardial infarction within 2–3 days of admission. The nurses collected information from the medical records and asked study subjects to complete the Beck Depression Inventory questionnaire during their stay in hospital and using a mailed questionnaire 30 days, 6 months and 1 year later. We obtained information on vital status for patients lost to follow-up from a central death registry. Results Of the 587 study subjects, 550 (94%) completed the Beck Depression Inventory at baseline and 191 (35%) had a score of 10 or more, indicating at least mild depression. Rates of depression did not vary over the follow-up period and were similar among patients admitted to tertiary care or community hospitals. Depressed patients were more likely to undergo catheterization (57% v. 47%, 95% confidence interval [CI] around the difference 0.1%–19.6%) and were more likely to undergo percutaneous coronary intervention (32% v. 24%, 95% CI around the difference 0.1%–16.2%) within 30 days of first admission to hospital. Patients with depression on admission had higher rates of a composite of cardiac complications, including recurrent ischemia, infarction or congestive heart failure during their first stay in hospital or readmission for angina, recurrent acute myocardial infarction, congestive heart failure or arrhythmia (adjusted hazard ratio 1

    Low magnesium levels are associated with an elevated risk of stroke. In this study, we investigated the association between magnesium levels on hospital admission and in-hospital mortality in acute ischemic stroke (AIS) patients. A total of 2,485 AIS patients, enrolled from December 2013 to May 2014 across 22 hospitals in Suzhou city, were included in this study. The patients were divided into 4 groups according to their level of admission magnesium: Q1 (<0.82 mmol/L), Q2 (0.82-0.89 mmol/L), Q3 (0.89-0.98 mmol/L), and Q4 (≥0.98 mmol/L). Cox proportional hazard model was used to estimate the effect of magnesium on all-cause in-hospital mortality in AIS patients. During hospitalization, 92 patients (3.7%) died from all causes. The lowest serum magnesium level (Q1) was associated with a 2.66-fold increase in the risk of in-hospital mortality in comparison to Q4 (hazard ratio [HR] 2.66; 95% CI 1.55-4.56; p-trend < 0.001). After adjusting for age, sex, time from onset to hospital admission, baseline National Institutes of Health Stroke Scale score, and other potential covariates, HR for Q1 was 2.03 (95% CI 1.11-3.70; p-trend = 0.014). Sensitivity and subgroup analyses further confirmed a significant association between lower magnesium levels and a high risk of in-hospital mortality. Decreased serum magnesium levels at admission were independently associated with in-hospital mortality in AIS patients. © 2017 S. Karger AG, Basel.

    Health forecasting can improve health service provision and individual patient outcomes. Environmental factors are known to impact chronic respiratory conditions such as asthma, but little is known about the extent to which these factors can be used for forecasting. Using weather, air quality and hospital asthma admissions, in London (2005-2006), two related negative binomial models were developed and compared with a naive seasonal model. In the first approach, predictive forecasting models were fitted with 7-day averages of each potential predictor, and then a subsequent multivariable model is constructed. In the second strategy, an exhaustive search of the best fitting models between possible combinations of lags (0-14 days) of all the environmental effects on asthma admission was conducted. Three models were considered: a base model (seasonal effects), contrasted with a 7-day average model and a selected lags model (weather and air quality effects). Season is the best predictor of asthma admissions. The 7-day average and seasonal models were trivial to implement. The selected lags model was computationally intensive, but of no real value over much more easily implemented models. Seasonal factors can predict daily hospital asthma admissions in London, and there is a little evidence that additional weather and air quality information would add to forecast accuracy.

    Laws banning tobacco smoking from public areas have been passed in several countries, including the region of Bremen, Germany at the end of 2007. The present study analyses the incidence of hospital admissions due to ST-elevation myocardial infarctions (STEMIs) before and after such a smoking ban was implemented, focusing on differences between smokers and non-smokers. In this respect, data of the Bremen STEMI Registry (BSR) give a complete epidemiological overview of a region in northwest Germany with approximately 800,000 inhabitants since all STEMIs are admitted to one central heart centre. Between January 2006 and December 2010, data from the BSR was analysed focusing on date of admission, age, gender, and prior nicotine consumption. A total of 3545 patients with STEMI were admitted in the Bremen Heart Centre during this time period. Comparing 2006-2007 vs. 2008-2010, hence before and after the smoking ban, a 16% decrease of the number of STEMIs was observed: from a mean of 65 STEMI/month in 2006-2007 to 55/month in 2008-2010 (p < 0.01). The group of smokers showed a constant number of STEMIs: 25/month in 2006-2007 to 26/month in 2008-2010 (+4%, p = 0.8). However, in non-smokers, a significant reduction of STEMIs over time was found: 39/month in 2006-2007 to 29/month in 2008-2010 (-26%, p < 0.01). The decline of STEMIs in non-smokers was consistently observed in all age groups and both sexes. Adjusting for potentially confounding factors like hypertension, obesity, and diabetes mellitus did not explain the observed decline. In the BSR, a significant decline of hospital admissions due to STEMIs in non-smokers was observed after the smoking ban in public areas came into force. No reduction of STEMI-related admissions was found in smokers. These results may be explained by the protection of non-smokers from passive smoking and the absence of such an effect in smokers by the dominant effect of active smoking. © The Author(s) 2013 Reprints and

    Stroke is a main cause of death and public health burden in China. The evidence on the burden of different strokes attack attribute to ambient temperature in China is limited. This study aimed to show the characteristics of stroke attack and the attributable risk due to temperature based on hospital admission data in Guangzhou, one of the most developed cities in China. From January 1, 2013 to December 31, 2015, 104,432 stroke hospitalizations in Guangzhou residents from 67 hospitals for stroke sentinel surveillance were registered. Characteristics of hospital admissions by gender, age group, calendar year and stroke subtype were analyzed, and distributed lag non-linear models were applied to evaluate the effects of temperature on stroke attack admissions. Stroke attack admissions increased from 31,851 to 36,755 through 2013 to 2015, increasing by 15.4%. An increasing trend in the risk of stroke attack with age was observed, irrespectively of stroke subtype and calendar year. People with hypertension were more likely to have an associated stroke than people without that. The effects of cold temperature on attack admissions for CBI and ICH strokes were significant. Overall, the percentages of CBI and ICH attack admissions attribute to cold temperature were 9.06% (95% CI: 1.84, 15.00) and 15.09% (95% CI: 5.86, 21.96), respectively. Besides, elderly people were more vulnerable to cold temperature than the young. Measures should be taken to increase public awareness about the ill effects of cold temperature on stroke attack, and educate the public about self-protection. Copyright © 2016 Elsevier B.V.

    The British Lung Foundation highlighted Southampton City as a hotspot for patients at future risk of chronic obstructive pulmonary disease (COPD) exacerbations due to severe deprivation levels and a high undiagnosed level of disease based on health economic modelling. We developed a strategy spanning primary and secondary care to reduce emergency admissions of patients with acute exacerbations of COPD and increase the diagnosed prevalence of COPD on general practitioner (GP) registers closer to that predicted from local modelling. A comprehensive 3-year audit of admissions was performed. Patients who had been admitted with an exacerbation to University Hospital Southampton three or more times in the previous 12 months were cohorted and cared for in a consultant-led, but community based, COPD service. Within primary care, a programme of education and case-based finding was delivered to most practices within the city. Thirty-four patients were found to be responsible for 176 admissions (22% of total COPD admissions) to the hospital. These 34 patients required 185 active interventions during the 12-month period but only 39 hospital admissions. The 30-day readmission rate dropped from 13.4 to 1.9% (P<0.01), confirming the contribution the cohort made to readmissions. Prior to the project, the registered Quality Outcomes Framework prevalence of COPD within the city was 1.5; after just 1 year of the project, the prevalence increased from 1.5 to 2.27%. The use of medical intelligence to investigate the underlying processes of COPD hospital admissions led to an effective intervention delivered in a consultant-led model.

    Objective To explore reasons for increased risk of hospital admission among south Asian patients with asthma. Design Qualitative interview study using modified critical incident technique and framework analysis. Setting Newham, east London, a deprived area with a large mixed south Asian population. Participants 58 south Asian and white adults with asthma (49 admitted to hospital with asthma, 9 not admitted); 17 general practitioners; 5 accident and emergency doctors; 2 out of hours general practitioners; 1 asthma specialist nurse. Main outcome measures Patients' and health professionals' views on influences on admission, events leading to admission, general practices' organisation and asthma strategies, doctor-patient relationship, and cultural attitudes to asthma. Results South Asian and white patients admitted to hospital coped differently with asthma. South Asians described less confidence in controlling their asthma, were unfamiliar with the concept of preventive medication, and often expressed less confidence in their general practitioner. South Asians managed asthma exacerbations with family advocacy, without systematic changes in prophylaxis, and without systemic corticosteroids. Patients describing difficulty accessing primary care during asthma exacerbations were registered with practices with weak strategies for asthma care and were often south Asian. Patients with easy access described care suggesting partnerships with their general practitioner, had better confidence to control asthma, and were registered with practices with well developed asthma strategies that included policies for avoiding hospital admission. Conclusions The different ways of coping with asthma exacerbations and accessing care may partly explain the increased risk of hospital admission in south Asian patients. Interventions that increase confidence to control asthma, confidence in the general practitioner, understanding of preventive treatment, and use of systemic corticosteroids in

    To find appropriate regression model specifications for counts of the daily hospital admissions of a Sydney cohort and determine which human heat stress indices best improve the models' fit. We built parent models of eight daily counts of admission records using weather station observations, census population estimates and public holiday data. We added heat stress indices; models with lower Akaike Information Criterion scores were judged a better fit. Five of the eight parent models demonstrated adequate fit. Daily maximum Simplified Wet Bulb Globe Temperature (sWBGT) consistently improved fit more than most other indices; temperature and heatwave indices also modelled some health outcomes well. Humidity and heat-humidity indices better fit counts of patients who died following admission. Maximum sWBGT is an ideal measure of heat stress for these types of Sydney hospital admissions. Simple temperature indices are a good fallback where a narrower range of conditions is investigated. Implications for public health: This study confirms the importance of selecting appropriate heat stress indices for modelling. Epidemiologists projecting Sydney hospital admissions should use maximum sWBGT as a common measure of heat stress. Health organisations interested in short-range forecasting may prefer simple temperature indices. © 2017 The Authors.

    There has been considerable publicity regarding population ageing and hospital emergency department (ED) overcrowding. Our study aims to investigate impact of one intervention piloted in Queensland Australia, the Hospital in the Nursing Home (HiNH) program, on reducing ED and hospital attendances from residential aged care facilities (RACFs). A quasi-experimental study was conducted at an intervention hospital undertaking the program and a control hospital with normal practice. Routine Queensland health information system data were extracted for analysis. Significant reductions in the number of ED presentations per 1000 RACF beds (rate ratio (95 % CI): 0.78 (0.67-0.92); p = 0.002), number of hospital admissions per 1000 RACF beds (0.62 (0.50-0.76); p < 0.0001), and number of hospital admissions per 100 ED presentations (0.61 (0.43-0.85); p = 0.004) were noticed in the experimental hospital after the intervention; while there were no significant differences between intervention and control hospitals before the intervention. Pre-test and post-test comparison in the intervention hospital also presented significant decreases in ED presentation rate (0.75 (0.65-0.86); p < 0.0001) and hospital admission rate per RACF bed (0.66 (0.54-0.79); p < 0.0001), and a non-significant reduction in hospital admission rate per ED presentation (0.82 (0.61-1.11); p = 0.196). Hospital in the Nursing Home program could be effective in reducing ED presentations and hospital admissions from RACF residents. Implementation of the program across a variety of settings is preferred to fully assess the ongoing benefits for patients and any possible cost-savings.

    Seasonal variation exists in the psychopathology of eating disorders. However, it is still unknown whether there is seasonal variation in eating disorder symptom severity. This study investigated seasonal trends in hospital admissions and birth dates among patients with eating disorders in Taiwan (25°N). Subgroup analyses by gender and comorbid affective disorders were also of interest. Data on all hospital admissions between 2000 and 2013 were collected from the Taiwan National Health Insurance Research Database, and 1954 patients with eating disorders were identified. Hospital admissions and birth dates were recorded by day. The four seasons and cross-seasons were defined by solstices and equinoxes. The expected distribution of births was determined using data from all patients hospitalized from 2000 to 2013 (n = 13,139,306). Hospital admissions among patients with eating disorders exceeded the rate of expected hospital admissions in the summer season (p < 0.001) and the autumn cross-season (p < 0.001). However, the seasonal (p = 0.421) and cross-seasonal (p = 0.24) distributions of birth dates among these patients did not differ from the expected distributions. Interestingly, hospital admissions among patients with comorbid affective disorders exceeded the rates of hospital admissions among non-affective patients during the spring (p = 0.004). Moreover, the number of non-affective patients born during autumn exceeded the birth rates of affective patients during this season (p = 0.001). Gender and comorbid affective disorders were not associated with cross-seasonal differences in either hospitalizations or dates of birth. Affective psychopathology in inpatients with eating disorders may substantially contribute to symptom severity that waxes and wanes with the seasons. Moreover, the seasonal distribution of birth dates was significantly different in patients without comorbid affective disorders.

    There are very limited data characterizing the epidemiology of anaphylaxis from low- and middle-income country settings. We aimed to estimate the frequency of anaphylaxis admissions to hospitals in Istanbul. We obtained data from all 45 hospitals in Istanbul over a 12-month period and used ICD-10 codes to extract data on those admitted with a recorded primary diagnosis of anaphylaxis. Because of concerns about possible under-coding, we undertook an additional analysis to identify patients admitted with two or more clinical codes for symptoms and/or signs suggestive of, but not coded as having, anaphylaxis. A total of 114 cases (79 people with anaphylaxis codes and 35 with symptoms and signs suggestive of anaphylaxis) were identified, giving an overall estimate of 1.95 cases per 100 000 person-years. The novel two-stage identification approach employed suggests significant under-recording of anaphylaxis in those admitted to hospitals in Istanbul. © 2012 John Wiley & Sons A/S.

    Patients admitted to a secure forensic hospital are at risk of a long hospital stay. Forensic hospital beds are a scarce and expensive resource and ability to identify the factors predicting length of stay at time of admission would be beneficial. The DUNDRUM-1 triage security scale and DUNDRUM-2 triage urgency scale are designed to assess need for therapeutic security and urgency of that need while the HCR-20 predicts risk of violence. We hypothesized that items on the DUNDRUM-1 and DUNDRUM-2 scales, rated at the time of pre-admission assessment, would predict length of stay in a medium secure forensic hospital setting. This is a prospective study. All admissions to a medium secure forensic hospital setting were collated over a 54 month period (n = 279) and followed up for a total of 66 months. Each patient was rated using the DUNDRUM-1 triage security scale and DUNDRUM-2 triage urgency scale as part of a pre-admission assessment (n = 279) and HCR-20 within 2 weeks of admission (n = 187). Episodes of harm to self, harm to others and episodes of seclusion whilst an in-patient were collated. Date of discharge was noted for each individual. Diagnosis at the time of pre-admission assessment (adjustment disorder v other diagnosis), predicted legal status (sentenced v mental health order) and items on the DUNDRUM-1 triage security scale and the DUNDRUM-2 triage urgency scale, also rated at the time of pre-admission assessment, predicted length of stay in the forensic hospital setting. Need for seclusion following admission also predicted length of stay. These findings may form the basis for a structured professional judgment instrument, rated prior to or at time of admission, to assist in estimating length of stay for forensic patients. Such a tool would be useful to clinicians, service planners and commissioners given the high cost of secure psychiatric care.

    Objectives: Reducing avoidable hospital readmissions presents an opportunity to improve health care quality and reduce avoidable costs. We studied the effect person-focused care may have on reducing avoidable admissions to the hospital. Methods: Among patients with heart failure discharged from the hospital, we evaluated the effect on 30-day readmissions of transitions-in-care interventions: home health visits, follow-up phone calls, and physician office visits. We also used a standardized diagnostic tool to interview readmitted patients to identify social reasons that may have contributed to the readmission. Finally, we used the learnings from both interventions to develop a new intervention: a single complex disease case conference that included the entire health care team. We measured hospital admissions for 21 patients during the 6 months before and after their complex case conferences. Results: Observed-over-expected hospital readmission rates were lowest for patients receiving a postdischarge visit with a home health nurse and a follow-up visit with their physician (0.54), compared with solely a physician visit (0.81), home health visit (1.2), or phone call (1.55). Various social issues may contribute to hospital readmissions, including caregiver knowledge, ability to care for oneself at home, and issues related to medications (adherence, ability to pay, and knowledge about potential side effects). Substantially fewer hospital admissions occurred after complex case conferences. Conclusions: Complex case conferences with disease-focused and person-focused interventions may be associated with reduced hospital admissions for patients with heart failure and multiple comorbidities.

    The health burden of alcohol use is socially and geographically patterned in many countries. Less is known about variations in this burden between ethnic groups and whether this differs across place of residence. National cross-sectional study using hospital admission data in England. Alcohol-related admission rates, where an alcohol-related condition was either the primary diagnosis (considered as the reason for admission) or a comorbidity, were calculated using ethnic group specific rates for English regions. In 2010/11 there were a total of 264,870 alcohol-related admissions in England. Admission rates were higher in the North of England than elsewhere (e.g. for primary diagnosis 161 per 100,000 population in the North vs. 62 per 100,000 in the South). These patterns were not uniform across ethnic groups however. For example, admission rates for alcohol-related comorbidity were four times higher among White Irish in London compared with those in the South of England (306 to 76 per 100,000) and four times higher in Indians living in the Midlands compared with those in the South of England (128 to 29 per 100,000). These patterns were similar for admissions with a comorbid alcohol-related condition. Geographical location may be an important determinant of within and between ethnic group variations in alcohol-related hospital admissions in England. While a number of factors were not examined here, this descriptive analysis suggests that this heterogeneity should be taken into account when planning interventions and services for the prevention and management of alcohol misuse.

    To evaluate the incidence, clinical features and outcome of acute poisoning in children of less than 6 years of age in northern Finland. Children hospitalized with acute poisoning at the Oulu University Hospital between 1991 and 2010 were retrospectively evaluated from hospital records. There were 334 hospital admissions due to acute poisoning during the study period, with an overall incidence rate of 5.2 per 10 000 per year, decreasing slightly from 6.7 in 1991-1995 to 4.5 in 2006-2010. Mean length of a hospital stay was 1.2 (SD ± 1.26) days. The most common substances ingested were terbutaline (12.3%), benzodiazepines (12.0%) and dishwasher powder (9.3%). Almost half of the patients were admitted to the paediatric intensive care unit, but most only required supportive care. Specific antidotes were administered in 16 cases. Three patients suffered from aspiration pneumonia as a result of ingesting poison, but no children died during the study. Poisoning is a fairly common cause of hospital admission in children under the age of six. In most cases, their clinical condition is good, and they can be discharged after a short surveillance period. ©2013 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    The aim was to explore the pattern of disease in staff associated with a bomber that crashed in 1968 when carrying nuclear bombs. The database was constructed from staff files of Danish workers employed from 1 April 1963 to 1 July 1971. Comparison was made between subsequent mortality and hospital admissions of workers employed during the clean up of the crashed bomber, and those employed outside this period. The study involved workers employed at Thule US air base in Greenland. During 1963-1971, 4322 staff were employed at the air base. Of these, 4265 (98.7%) were identified in 1987, among whom 1202 workers were employed during the clean up period. No differences were found in total mortality, or mortality from cancer, heart disease, or accidents, after allowing for differences in age, marital status, or length of employment, between those employed during the clean up period and those employed at other times. Similarly, no difference in hospital admissions between the two groups was found. No harmful effects on health due to the crash were found, as measured by mortality and hospital admissions.

    To describe and compare logistic regression and neural network modeling strategies to predict hospital admission or transfer following initial presentation to Emergency Department (ED) triage with and without the addition of natural language processing elements. Using data from the National Hospital Ambulatory Medical Care Survey (NHAMCS), a cross-sectional probability sample of United States EDs from 2012 and 2013 survey years, we developed several predictive models with the outcome being admission to the hospital or transfer vs. discharge home. We included patient characteristics immediately available after the patient has presented to the ED and undergone a triage process. We used this information to construct logistic regression (LR) and multilayer neural network models (MLNN) which included natural language processing (NLP) and principal component analysis from the patient's reason for visit. Ten-fold cross validation was used to test the predictive capacity of each model and receiver operating curves (AUC) were then calculated for each model. Of the 47,200 ED visits from 642 hospitals, 6,335 (13.42%) resulted in hospital admission (or transfer). A total of 48 principal components were extracted by NLP from the reason for visit fields, which explained 75% of the overall variance for hospitalization. In the model including only structured variables, the AUC was 0.824 (95% CI 0.818-0.830) for logistic regression and 0.823 (95% CI 0.817-0.829) for MLNN. Models including only free-text information generated AUC of 0.742 (95% CI 0.731- 0.753) for logistic regression and 0.753 (95% CI 0.742-0.764) for MLNN. When both structured variables and free text variables were included, the AUC reached 0.846 (95% CI 0.839-0.853) for logistic regression and 0.844 (95% CI 0.836-0.852) for MLNN. The predictive accuracy of hospital admission or transfer for patients who presented to ED triage overall was good, and was improved with the inclusion of free text data from a patient

    The burden of Neurological diseases may be on the increase especially in developing countries. Improved outcome in these settings may require appreciation of the spectrum of Neurological diseases and the impediments to their management. We aim to determine the profile of neurological admissions and the challenges of managing these diseases at the University of Nigeria Teaching Hospital Enugu South East Nigeria. Analysis of Neurological admissions into the medical wards of the University of Nigeria Teaching Hospital Enugu from January 2003 to December 2007. Neurological admissions comprise about 14.8% of medical admissions. There were 640 (51%) males and 609 (49%) females. The spectrum of neurological diseases were stroke 64.9%, central nervous system infections (21.8% ), HIV related neurological diseases 3.5%, hypertensive encephalopathy (3.4%), dementia (3%), subarachnoid haemorrhage (2.2%), Guillian Barre syndrome (1.2%), Parkinson's disease (1.1%), myasthenia gravis (1.0%), motor neurone disease and peripheral neuropathy and accounted for 0.8% and 0.6% respectively. Overall, noninfectious disease accounted for 78.2% of neurological admissions while infectious diseases accounted for 11.8%. A wide spectrum of neurological diseases occurs in our setting. The high incidence of CNS infections indicates that efforts should be geared towards preventive measures. A major challenge to be addressed in the management of neurological diseases in our setting is the lack of specialized facilities.

    Our main purpose was to evaluate the organizational appropriateness of admissions made in a university hospital, by comparing two iso-gravity classification systems, APR-DRG and Disease Staging, with the Italian version of AEP (PRUO). Our analysis focused on admissions made in 2001, related to specific Diagnosis Related Groups (DRGs), which, according an Italian Law, would be considered at high risk of inappropriateness, if treated as ordinary admissions. The results obtained by using the 2 classification systems did not show statistically significant differences with respect to the total number of admissions. On the other hand, some DRGs showed statistically significant differences due to different algorithms of attribution of the severity levels used by the two systems. For almost all of the DRGs studied, the AEP-based analysis of a sample of medical records showed an higher number of inappropriate admissions in comparison with the number expected by iso-gravity classification methods. The difference is possibly due to the percentage limits of tolerability fixed by the Law for each DRG. Therefore, the authors suggest an integrated use of the two methods to evaluate organizational appropriateness of hospital admissions.

    Non-communicable diseases are the main reasons for admission to the medical wards in high-income countries. While in low and middle income countries communicable diseases are the main reasons for admission to the medical wards. However, in some low and middle income countries the reasons for admission are changing from communicable diseases to non-communicable diseases. But, data on reasons for admission to the medical wards of low income countries is scarce. Therefore, this study takes one year data from a low income country referral hospital aiming at describing the recent reasons and outcomes of medical admissions to see whether there is a change in reasons for admission and the outcome. A retrospective study examined patient case notes and ward registration books of medical admissions at Jimma University Specialized Hospital from January 1, 2008 to December 31, 2008. Socio-demographic variables, reasons and outcomes of admission were some of the variables recorded during the data collection. The International Statistical Classification of Disease was used for sorting and categorizing the diagnosis. The data was then analyzed using SPSS windows version 13.0. A total of 610 patient case notes were reviewed. The mean age of the patients was 36 years (SD ± 15.75). The highest number of admissions 218 (35.7%) was among the age groups 21 to 30 years. Communicable diseases; namely severe community acquired pneumonia 139(22.8%), all infectious and parasitic diseases category 100 (16.4%), and pyogenic as well as chronic meningitis 80(13.1%) were the most common reasons for admission. The death rate among patients admitted to the medical wards was 12.6%. Communicable diseases were still the common reasons for medical admissions at Jimma University Specialized Hospital. The outcome of medical admissions has not changed over sixteen years.

    We report on comparative analyses of small area variation in rates of acute hospital admissions for psychiatric conditions in Greater London around the year 1998 and in New York City (NYC) in 2000. Based on a theoretical model of the factors likely to influence psychiatric admission rates, and using data from the most recent population censuses and other sources, we examine the association with area indicators designed to measure access to hospital beds, socio-economic deprivation, social fragmentation and ethnic/racial composition. We report results on admissions for men and women aged 15-64 for all psychiatric conditions (excluding self-harm), drug-related substance abuse/addiction, schizophrenia and affective disorders. The units of analysis in NYC were 165 five-digit Zip Code Areas and, in London, 760 electoral wards as defined in 1998. The analysis controls for age and sex composition and, as a proxy for access to care, spatial proximity to hospitals with psychiatric beds. Poisson regression modeling incorporating random effects was used to control for both overdispersion in the counts of admissions and for the effects of spatial autocorrelation. The results for NYC and London showed that local admission rates for all types of condition were positively and significantly associated with deprivation and the association is independent of demographic composition or 'access' to beds. In NYC, social fragmentation showed a significant association with admissions due to affective disorders and schizophrenia, and for drug dependency among females. Racial minority concentration was significantly and positively associated with admissions for schizophrenia. In London, social fragmentation was associated positively with admissions for men and women due to schizophrenia and affective disorders. The variable measuring racial/ethnic minority concentration for London wards showed a negative association with admission rates for drug dependency and for affective disorders. We

    Numbers of crashes, rates of police-reported injury severity, and hospital admission rates were calculated for the ten year period between 2001 and 2010 in Maryland. Comparisons were made for two 5-year periods of 2001–2005 and 2006–2010. Crash characteristics remained similar for the two five-year periods, but there was a significant increase in occupant age. Declines in police-reported injury severity were noted for each of four age groups: 16–29, 30–54, 55–64, and 65+, with smaller declines among older occupants. In addition, there were significant declines in hospital admissions, comparing the two time periods. Although reductions in crashes may be attributable to various roadway, behavioral, and other safety improvement efforts, reductions in hospital admission rates most likely reflect major improvements in crashworthiness implemented during the past decade. For those admitted to hospitals, significant increases in injury severity were noted between the first and second time periods. There was an association between age and ISS, a measure of total bodily injury, with the highest ISS scores noted for the youngest and oldest groups (16–29 and 55+, respectively). In addition, there was a significant increase in the mean age over time, from 39 in 2001 to 43 in 2010, p<.001. In general, the incidence and severity of injuries increased for all body regions. There was also a significant increase in hospital mortality, although length of hospital stay remained the same. Given these trends, increased efforts need to focus on both injury prevention and treatment for the increasing population of older, sometimes frail, vehicle occupants. PMID:24406962

    Red blood cell distribution width (RDW) is significantly associated with a variety of human disorders. This study aimed to investigate whether RDW value at admission may predict the need of hospitalisation in patients presenting to the emergency department (ED) with acute allergic reactions. The study population consisted of adult patients (aged > 17) admitted to the ED for acute allergic reactions. One hundred and thirty-two subjects were included, 12 of whom (9%) required hospital admission for severity of symptoms. Patients who needed hospital admission displayed significantly lower values of haemoglobin and significantly higher values of RDW-coefficient of variation (RDW-CV). In multivariate analysis, haemoglobin and RDW-CV were found to be independent predictors of hospital admission. The area under the curve (AUC), sensitivity and specificity for predicting hospital admission were 0.72, 0.88 and 0.42 for haemoglobin and 0.73, 0.88 and 0.50 for RDW-CV, respectively. The combination of these tests (both positive) was characterised by 0.76 AUC, 0.83 sensitivity, 0.67 specificity, 0.96 negative predictive value and 0.30 positive predictive. The results of this study suggest that two common and inexpensive parameters such as haemoglobin and RDW are independent predictors of hospital admission in patients presenting to the ED with acute allergic reactions.

    Background Adverse drug reactions (ADRs) are the major cause of medication-related hospital admissions in older patients living in the community. This study aimed to develop and validate a score to predict ADR-related hospitalization in people aged ≥65 years. Methods ADR-related hospitalization and its risk factors were determined using a prospective, cross-sectional study in patients aged ≥65 years admitted to two hospitals. A predictive model was developed in the derivation cohort (n = 768) and the model was applied in the validation cohort (n = 240). ADR-related hospital admission was determined through expert consensus from comprehensive reviews of medical records and patient interviews. The causality and preventability of the ADR were assessed based on the Naranjo algorithm and modified Schumock and Thornton criteria, respectively. Results In the derivation sample (mean [±SD] age, 80.1±7.7 years), 115 (15%) patients were admitted due to a definite or probable ADR; 92.2% of these admissions were deemed preventable. The number of antihypertensives was the strongest predictor of an ADR followed by presence of dementia, renal failure, drug changes in the preceding 3 months and use of anticholinergic medications; these variables were used to derive the ADR prediction score. The predictive ability of the score, assessed from calculation of the area under the receiver operator characteristic (ROC) curve, was 0.70 (95% confidence interval (CI) 0.65–0.75). In the validation sample (mean [±SD] age, 79.6±7.6 years), 30 (12.5%) patients’ admissions were related to definite or probable ADRs; 80% of these admissions were deemed preventable. The area under the ROC curve in this sample was 0.67 (95% CI 0.56–0.78). Conclusions This study proposes a practical and simple tool to identify elderly patients who are at an increased risk of preventable ADR-related hospital admission. Further refinement and testing of this tool is necessary to implement the score in

    To identify the most common reasons for acute care hospital admissions among youth (age range, 13-17.9y) and young adults (age range, 23-32.9y) with cerebral palsy (CP). We completed a secondary analysis of data from the Canadian Institute for Health Information (CIHI) to determine the most frequently observed reasons for admissions and the associated lengths of stay (LOS). Participants were identified from 6 children's treatment centers in Ontario, Canada. Health records data from youth with CP (n=587) and young adults with CP (n=477) contributed to this study. Not applicable. The most common reasons for hospital admission, relative frequencies of admissions for each reason, and mean LOS were reported. The analysis of CIHI records identified epilepsy and pneumonia as the top 2 reasons for admissions in both age groups. Both age groups were commonly admitted because of infections other than pneumonia and urinary tract infections (UTIs), gastrointestinal (GI) problems such as malabsorption, and mental illness. The reasons that were unique to youth included orthopedic and joint-related issues, other respiratory problems, and scoliosis. In young adults, mental illness was the third most common reason for admission, followed by lower GI or constipation problems, malnutrition or dehydration, upper GI problems, fractures, and UTIs. This article provides important clinical information that can be used in the training of physicians and health care providers, and to guide future planning of ambulatory care services to support the clinical management of persons with CP over their lifespan.

    Recent recommendations for physicians in the UK outline key aspects of care that should improve patient outcomes and experience in acute hospital care. Included in these recommendations are Consultant patterns of work to improve timeliness of clinical review and improve continuity of care. This study used a contemporaneous validated survey compared with clinical outcomes derived from Hospital Episode Statistics, between April 2009 and March 2010 from 91 acute hospital sites in England to evaluate systems of consultant cover for acute medical admissions. Clinical outcomes studied included adjusted case fatality rates (aCFR), including the ratio of weekend to weekday mortality, length of stay and readmission rates. Hospitals that had an admitting Consultant presence within the Acute Medicine Unit (AMU, or equivalent) for a minimum of 4 hours per day (65% of study group) had a lower aCFR compared with hospitals that had Consultant presence for less than 4 hours per day (p<0.01) and also had a lower 28 day re-admission rate (p<0.01). An ‘all inclusive’ pattern of Consultant working, incorporating all the guideline recommendations and which included the minimum Consultant presence of 4 hours per day (29%) was associated with reduced excess weekend mortality (p<0.05). Hospitals with >40 acute medical admissions per day had a lower aCFR compared to hospitals with fewer than 40 admissions per day (p<0.03) and had a lower 7 day re-admission rate (p<0.02). This study is the first large study to explore the potential relationships between systems of providing acute medical care and clinical outcomes. The results show an association between well-designed systems of Consultant working practices, which promote increased patient contact, and improved patient outcomes in the acute hospital setting.

    We aimed to assess the impact of UK primary care policy reforms implemented in April 2004 on potentially avoidable unplanned short-stay hospital admissions for children with primary care-sensitive conditions. We conducted an interrupted time series analysis of hospital admissions for all children aged younger than 15 years in England between April 2000 and March 2012 using data from National Health Service public hospitals in England. The main outcomes were annual short-stay (<2-day) unplanned hospital admission rates for primary care-sensitive infectious and chronic conditions. There were 7.8 million unplanned admissions over the study period. More than one-half (4,144,729 of 7,831,633) were short-stay admissions for potentially avoidable infectious and chronic conditions. The primary care policy reforms of April 2004 were associated with an 8% increase in short-stay admission rates for chronic conditions, equivalent to 8,500 additional admissions, above the 3% annual increasing trend. Policy reforms were not associated with an increase in short-stay admission rates for infectious illness, which were increasing by 5% annually before April 2004. The proportion of primary care-referred admissions was falling before the reforms, and there were further sharp reductions in 2004. The introduction of primary care policy reforms coincided with an increase in short-stay admission rates for children with primary care-sensitive chronic conditions, and with more children being admitted through emergency departments. Short-stay admission rates for primary care-sensitive infectious illness increased more steadily and could be related to lowered thresholds for hospital admission. © 2015 Annals of Family Medicine, Inc.

    The aim of the study was to measure the effect of colder winters compared to warmer winters on hospital admission rates in Suffolk County. The setting of this study was Suffolk County in eastern England. The period of the study was financial years 2003/04-2012/13. The study was an analytic ecological study. Analysis involved calculation of rate ratios of hospital admission rates in colder winters compared to warmer winters, in all persons and the elderly. The main finding of the study was that all rate ratios for hospital admission rates in colder winters compared to warmer winters were significantly raised with effects of 2-5%. Rate ratios for all admissions in persons of all ages and persons aged 65 years and over were, respectively, 1.02 (99% confidence interval (CI): 1.01, 1.03; P < 0.001) and 1.02 (99% CI: 1.01, 1.04; P < 0.001). Rate ratios for emergency admissions in persons of all ages and persons aged 65 years and over were, respectively, 1.05 (99% CI: 1.03, 1.06; P < 0.001) and 1.04 (99% CI: 1.01, 1.06; P < 0.001). In Suffolk County, hospital admission rates are significantly raised in colder winters compared to warmer winters. This evidence may be useful in planning hospital services. © The Author 2017.

    Extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae have become prevalent in both the hospital and the community. We describe the epidemiology of ESBL-producing isolates and patient characteristics at hospital admission. Data on clinical properties, medical history, previous hospitalizations, and previous antibiotic treatments were collected. ESBL genes (bla(CTX-M), bla(TEM), and bla(SHV)) were identified by polymerase chain reaction. One hundred and sixteen patients carried 122 ESBL-producing Enterobacteriaceae: 79 Escherichia coli, 26 Klebsiella pneumoniae, 16 Enterobacter spp., and 1 Citrobacter koseri. ESBL-producing E. coli were associated with admission from home (odds ratio (OR) 3.04, p = 0.02) and a history of recent urinary tract infection (OR 3.38, p = 0.04), and exhibited a lower rate of antimicrobial resistance to aminoglycosides (p ≤ 0.005) and co-trimoxazole (p = 0.003), whereas other ESBL-producing Enterobacteriaceae tended to be associated with a recent surgery (OR 0.42, p = 0.057). Although the CTX-M enzymes were more frequently found in E. coli (76%), they were also identified in other Enterobacteriaceae (45%), suggesting penetration of CTX-M-type enzymes into both community- and hospital-acquired enterobacterial species.

    A number of time-series studies have associated PM2.5 (particulate matter with aerodynamic diameter less than 2.5 μm) mass and components with various health outcomes. No studies have yet examined the associations between PM2.5 components and hospital admissions among a privately insured population. We estimated the short-term associations between exposure to PM2.5 mass and components and emergency hospital admissions for all-cause and cause-specific diseases in Greater Houston, Texas, during 2008-2013 using Blue Cross Blue Shield Texas claims data. A total of 90,085 emergency hospital admissions were included in this study, with an average of 34 ± 10 admissions per day. We selected 20 PM2.5 components from the U.S. Environmental Protection Agency's Chemical Speciation Network site located in Houston, and then applied Poisson regression models to assess the short-term effects of PM2.5 mass and species on emergency hospital admissions. Effects were estimated without adjustment for other airborne pollutants. PM2.5 mass was not statistically significantly associated with increased all-cause emergency hospital admissions and selected cause-specific admissions. For selected PM2.5 species, we found interquartile range increases in arsenic (0.001 μg/m3) and copper (0.017 μg/m3) were significantly (P < 0.05) associated with increased admissions for stroke, (5.98% [95% confidence interval (CI): 0.73, 11.50%]) and pneumonia (4.07% [95% CI: 0.37, 7.90%]), respectively. Seasonal analysis showed weak variation among PM2.5 mass and components, except that nickel significantly increased all-cause emergency hospital admissions (2.16% [95% CI: 0.21, 4.14%]) during the warm season. Our findings suggest that hospital admissions in the privately insured population are slightly affected by ambient fine particulate matter air pollution.

    People exhibiting serious behavioural and psychological symptoms of dementia are usually voluntarily or involuntarily committed to psychiatric hospitals for treatment. In Japan, the average hospital stay for individuals with dementia is about 2 years. Ideally, individuals should be discharged once their symptoms have subsided. However, we see cases in Japan where individuals remain institutionalized long after behavioural and psychological symptoms of dementia are no longer apparent. This study will attempt to identify factors contributing to shorter stays in psychiatric hospitals for dementia patients. Questionnaires consisting of 17 items were mailed to 121 psychiatric hospitals with dementia treatment wards in western Japan. Out of 121 hospitals that received the questionnaires, 45 hospitals returned them. The total number of new patient admissions at all 45 hospitals during the month of August 2014 was 1428, including 384 dementia patients (26.9%). The average length of stay in the dementia wards in August 2014 was 482.7 days. Our findings revealed that the rate of discharge after 2 months was 35.4% for the dementia wards. In addition, we found that the average stay in hospitals charging or planning to charge the rehabilitation fee to dementia patients was significantly shorter than in hospitals not charging the rehabilitation fee. In Japan, dementia patients account for over 25% of new admissions to psychiatric hospitals with dementia wards. The average length of stay in a psychiatric hospital dementia ward is more than 1 year. A discharge after fewer than 2 months is exceedingly rare for those in a dementia ward compared with dementia patients in other wards. If institutions focus on rehabilitation, it may be possible to shorten the stay of dementia patients in psychiatric hospitals. © 2017 Japanese Psychogeriatric Society.

    Objectives. We examined the impact of Arizona's May 2007 comprehensive statewide smoking ban on hospital admissions for diagnoses for which there is evidence of a causal relationship with secondhand smoke (SHS) exposure (acute myocardial infarction [AMI], angina, stroke, and asthma). Methods. We compared monthly hospital admissions from January 2004 through May 2008 for these primary diagnoses and 4 diagnoses not associated with SHS (appendicitis, kidney stones, acute cholecystitis, and ulcers) for Arizona counties with preexisting county or municipal smoking bans and counties with no previous bans. We attributed reductions in admissions to the statewide ban if they occurred only in diagnoses associated with SHS and if they were larger in counties with no previous bans. We analyzed the data with Poisson regressions, controlling for seasonality and admissions trends. We also estimated cost savings. Results. Statistically significant reductions in hospital admissions were seen for AMI, angina, stroke, and asthma in counties with no previous bans over what was seen in counties with previous bans. No ban variable coefficients were statistically significant for diagnoses not associated with SHS. Conclusions. Arizona's statewide smoking ban decreased hospital admissions for AMI, stroke, asthma, and angina. PMID:20466955

Moderately (n = 614) and severely (n = 1294) impaired patients who had a stroke who were admitted to the facility between 2002 and 2006. Not applicable. Change in total, motor, and cognitive Functional Independence Measure (FIM) scores between IRH admission and discharge. After controlling for patient demographics and initial medical conditions and functional status, shorter periods from stroke onset to IRH admission were significantly associated with greater functional gains for these patients during IRH hospitalization. Moderately impaired patients achieved a greater total FIM gain when admitted to an IRH within 21 days of stroke. Severely impaired patients showed a gradient relationship between time to IRH admission and total FIM gain, with significantly different functional gain if admitted to an IRH within 30 and 60 days after stroke diagnosis. Results of multiple regression analysis also showed that age, race/ethnicity, side of stroke, history of a previous stroke, functional measures at IRH admission, IRH length of stay, and selected medications were associated with total, motor, and cognitive FIM score changes. In addition, certain factors such as older age, diagnosis of a hemorrhagic stroke or a previous history of stroke, and initial functional status were associated with longer periods between diagnosis and admission to an IRH after the stroke occurred. Our findings are consistent with the hypothesis that earlier transfer to an IRH may lead to better functional improvement after stroke. However, certain factors such as age, race/ethnicity, initial medical conditions and functional status, and length of stay at an IRH contributed to functional gain. Factors affecting the time to IRH admission also were addressed. Copyright © 2011 American Academy of Physical Medicine

    This study was undertaken to determine whether there was an association between coarse particles (PM₂.₅-₁₀) levels and frequency of hospital admissions for respiratory diseases (RD) in Kaohsiung, Taiwan. Hospital admissions for RD including chronic obstructive pulmonary disease (COPD), asthma, and pneumonia, and ambient air pollution data levels for Kaohsiung were obtained for the period from 2006 to 2010. The relative risk of hospital admissions for RD was estimated using a case-crossover approach, controlling for weather variables, day of the week, seasonality, and long-term time trends. For the single pollutant model (without adjustment for other pollutants), increased rate of admissions for RD were significantly associated with higher coarse PM levels only on cool days (<25 °C), with a 10 µg/m³ elevation in PM₂.₅-₁₀ concentrations associated with a 3% (95% CI = 1%-5%) rise in COPD admissions, 4% (95% CI = 1%-7%) increase in asthma admissions, and 3% (95% CI = 2%-4%) rise in pneumonia admissions. No significant associations were found between coarse particle levels and the number of hospital admissions for RD on warm days. In the two-pollutant models, PM₂.₅-₁₀ levels remained significantly correlated with higher rate of RD admissions even controlling for sulfur dioxide, nitrogen dioxide, carbon monoxide, or ozone on cool days. This study provides evidence that higher levels of PM₂.₅-₁₀ enhance the risk of hospital admissions for RD on cool days.

    The aim of this study was to evaluate the relationship between the risk of hospital admission for myocardial infarction (MI) and the daily weather conditions during the winters of 1998-2003, according to an air-mass-based synoptic climatological approach. The effects of time lag and 2-day sequences with specific air mass types were also investigated. Studies concerning the relationship between atmospheric conditions and human health need to take into consideration simultaneous effects of many weather variables. At the moment few studies have surveyed these effects on hospitalizations for MI. Analyses were concentrated on winter, when the maximum peak of hospitalization occurred. An objective daily air mass classification by means of statistical analyses based on ground meteorological data was carried out. A comparison between air mass classification and hospital admissions was made by the calculation of a MI admission index, and to detect significant relationships the Mann-Whitney U test, the analysis of variance, and the Bonferroni test were used. Significant increases in hospital admissions for MI were evident 24h after a day characterized by an anticyclonic continental air mass and 6 days after a day characterized by a cyclonic air mass. Increased risk of hospitalization was found even when specific 2-day air mass sequences occurred. These results represent an important step in identifying reliable linkages between weather and health.

    The emergency regarding recent immigration waves into Italy makes continued healthcare monitoring of these populations necessary. Through a survey of hospital admissions carried out during the last five years at the S. Orsola-Malpighi General Hospital of Bologna (Italy), all causes of admission of these subjects were evaluated, together with their correlates. Subsequently, we focused on admissions due to infectious diseases. All available data regarding foreign citizens admitted as inpatients or in Day-Hospital settings of our teaching hospital from January 1, 1999, to March 31, 2004, were assessed. Diagnosis-related group (DRG) features, and single discharge diagnoses, were also evaluated, and a further assessment of infectious diseases was subsequently made. Within a comprehensive pool of 339,051 hospitalized patients, foreign citizen discharges numbered 7,312 (2.15%), including 2,542 males (34.8%) and 4,769 females (65.2%). Males had a mean age of 36.8+/-14.7 years, while females were aged 30.8+/-12.2 years. In the assessment of the areas of origin, 34.6% of hospitalizations were attributed to patients coming from Eastern Europe, 15.3% from Northern Africa, 7.3% (comprehensively) from Western Europe and United States, 6.9% from the Indian subcontinent, 5.9% from sub-Saharan Africa, 5.7% from Latin America, 4.1% from China, 2.5% from the Philippines, and 1.1% from the Middle East. Among women, most hospitalizations (58.8%) were due to obstetrical-gynecological procedures or diseases, including assistance with delivery (27.1%), and pregnancy complications (18.7%), followed by psycho-social disturbances (5.9%), malignancies (5.1%), gastrointestinal diseases (4.7%), and voluntary pregnancy interruption (4.4%). Among men, the most frequent causes of admissions were related to trauma (15.9%), followed by gastroenteric disorders (12%), heart-vascular diseases (8.9%), psycho-social disorders (8.4%), respiratory (7.1%), kidney (6.1%), liver (5.2%), and metabolic (4

    The effect of socioeconomic stressors on the incidence of cardiovascular disease (CVD) is currently open to debate. Using time-series analysis, our study aimed to evaluate the relationship between unemployment rate and hospital admission for acute myocardial infarction (AMI) and stroke in Brazil over a recent 11-year span. Data on monthly hospital admissions for AMI and stroke from March 2002 to December 2013 were extracted from the Brazilian Public Health System Database. The monthly unemployment rate was obtained from the Brazilian Institute for Applied Economic Research, during the same period. The autoregressive integrated moving average (ARIMA) model was used to test the association of temporal series. Statistical significance was set at p<0.05. From March 2002 to December 2013, 778,263 admissions for AMI and 1,581,675 for stroke were recorded. During this time period, the unemployment rate decreased from 12.9% in 2002 to 4.3% in 2013, while admissions due to AMI and stroke increased. However, the adjusted ARIMA model showed a positive association between the unemployment rate and admissions for AMI but not for stroke (estimate coefficient=2.81±0.93; p=0.003 and estimate coefficient=2.40±4.34; p=0.58, respectively). From 2002 to 2013, hospital admissions for AMI and stroke increased, whereas the unemployment rate decreased. However, the adjusted ARIMA model showed a positive association between unemployment rate and admissions due to AMI but not for stroke. Further studies are warranted to validate our findings and to better explore the mechanisms by which socioeconomic stressors, such as unemployment, might impact on the incidence of CVD.

    To analyze the nutrition status of the pediatric patients at the time of hospital admission throughout a calendar year in a tertiary level hospital and to identify those patients and/or groups of pathologies with a higher risk of malnutrition. Retrospective evaluation of nutrition status of 852 patients hospitalized in 2013 in a pediatric hospital (462 males and 390 females). Sex, age, body mass index at the moment of admission and days of hospitalization and diagnosis codified according to the International Classification of Diseases were registered. The prevalence of malnutrition patients registered at the moment of admission was 8.2%. Excess body weight (overweight and obesity) was detected in 18% of the patients. The diseases of the nervous system (22.9%), together with the diseases of the respiratory system, the infectious diseases (18.6%), the congenital malformations (11.4%) and the diseases of the genitorurinary system (8.6%) account for 84.4% of the cases with malnutrition. The overall prevalence rate for malnutrition in pediatric patients at the moment of admission in our hospital was 8.2%, being this figure similar to those published in occidental countries. It should be mandatory to accomplish an initial screening and follow up during hospitalization of younger patients and those suffering from diseases of the nervous and/or respiratory system and, especially, from congenital diseases.

    Chronic Obstructive Pulmonary Disease (COPD) accounts for around 4% of all public hospital annual admissions in Hong Kong. By year 2020, COPD will be ranked fifth among the conditions with the highest burden to the society. This study identifies admission and unplanned readmission of COPD patients, factors affecting unplanned readmission, and estimates its cost burden on the public healthcare system in Hong Kong. This is a retrospective study analyzing COPD admissions to all public hospitals in Hong Kong. All admission episodes to acute medical wards with the principal diagnosis of COPD (ICD-9:490-492, 494-496) from January 2006 to December 2007 were captured. Unplanned readmission was defined as an admission which followed a previous admission within 30 days. In 2006 and 2007, 65497 (8.0%) of episodes from medical wards were identified as COPD admissions, and among these, 15882 (24.2%) were unplanned readmissions. The mean age of COPD patients was 76.81 ± 9.59 years and 77% were male. Unplanned readmission was significantly associated with male gender, receiving public assistance and living in nursing homes while no association was found with the Charlson comorbidity index. Patients who were readmitted unplanned had a significant longer acute length of stay (β = 0.3894, P < 0.001) after adjustment for other covariates. Unplanned readmission of COPD patients has a huge impact on the public healthcare system. A systematic approach in programme provision and a good discharge planning process targeting on COPD patients who are at high risk of unplanned readmission are essential.

    Background Multiple sclerosis (MS) is a chronic, inflammatory, demyelinating disease of the central nervous system, characterized by recurrent relapses of inflammation that cause mild to severe disability. Exposure to airborne particulate matter (PM) has been associated with acute increases in systemic inflammatory responses and neuroinflammation. In the present study, we hypothesize that exposure to PM < 10 µm in diameter (PM10) might increase the occurrence of MS-related hospitalizations. Methods We obtained daily concentrations of PM10 from 53 monitoring sites covering the study area and we identified 8287 MS-related hospitalization through hospital admission-discharge records of the Lombardy region, Italy, between 2001 and 2009. We used a Poisson regression analysis to investigate the association between exposure to PM10 and risk of hospitalization. Results A higher RR of hospital admission for MS relapse was associated with exposure to PM10 at different time intervals. The maximum effect of PM10 on MS hospitalization was found for exposure between days 0 and 7: Hospital admission for MS increased 42% (95%CI 1.39–1.45) on the days preceded by one week with PM10 levels in the highest quartile. The p-value for trend across quartiles was < 0.001. Conclusions These data support the hypothesis that air pollution may have a role in determining MS occurrence and relapses. Our findings could open new avenues for determining the pathogenic mechanisms of MS and potentially be applied to other autoimmune diseases. PMID:26624240

    This study aims to examine the effect of short-term changes in the concentration of particulate matter of diameter ≤2.5 µm (PM 2.5 ) and ≤10 µm (PM 10 ) on pediatric hospital admissions for pneumonia in Jinan, China. It explores confoundings factors of weather, season, and chemical pollutants. Information on pediatric hospital admissions for pneumonia in 2014 was extracted from the database of Jinan Qilu Hospital. The relative risk of pediatric hospital admissions for pneumonia was assessed using a case-crossover approach, controlling weather variables, day of the week, and seasonality. The single-pollutant model demonstrated that increased risk of pediatric hospital admissions for pneumonia was significantly associated with elevated PM 2.5 concentrations the day before hospital admission and elevated PM 10 concentrations 2 days before hospital admission. An increment of 10 μg/m 3 in PM 2.5 and PM 10 was correlated with a 6% (95% CI 1.02--1.10) and 4% (95% CI 1.00-1.08) rise in number of admissions for pneumonia, respectively. In two pollutant models, PM 2.5 and PM 10 remained significant after inclusion of sulfur dioxide or nitrogen dioxide but not carbon monoxide. This study demonstrated that short-term exposure to atmospheric particulate matter (PM 2.5 /PM 10 ) may be an important determinant of pediatric hospital admissions for pneumonia in Jinan, China. This study demonstrated that short-term exposure to atmospheric particulate matter (PM 2.5 /PM 10 ) may be an important determinant of pediatric hospital admissions for pneumonia in Jinan, China, and suggested the relevance of pollutant exposure levels and their effects. As a specific group, children are sensitive to airborne particulate matter. This study estimated the short-term effects attribute to other air pollutants to provide references for relevant studies.

    To estimate the incidence, duration and cost of futile treatment for end-of-life hospital admissions. Retrospective multicentre cohort study involving a clinical audit of hospital admissions. Three Australian public-sector tertiary hospitals. Adult patients who died while admitted to one of the study hospitals over a 6-month period in 2012. Incidences of futile treatment among end-of-life admissions; length of stay in both ward and intensive care settings for the duration that patients received futile treatments; health system costs associated with futile treatments; monetary valuation of bed days associated with futile treatment. The incidence rate of futile treatment in end-of-life admissions was 12.1% across the three study hospitals (range 6.0%-19.6%). For admissions involving futile treatment, the mean length of stay following the onset of futile treatment was 15 days, with 5.25 of these days in the intensive care unit. The cost associated with futile bed days was estimated to be $AA12.4 million for the three study hospitals using health system costs, and $A988 000 when using a decision maker's willingness to pay for bed days. This was extrapolated to an annual national health system cost of $A153.1 million and a decision maker's willingness to pay of $A12.3 million. The incidence rate and cost of futile treatment in end-of-life admissions varied between hospitals. The overall impact was substantial in terms of both the bed days and cost incurred. An increased awareness of these economic costs may generate support for interventions designed to reduce futile treatments. We did not include emotional hardship or pain and suffering, which represent additional costs. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Both asymptomatic and symptomatic Clostridium difficile carriers contribute to new colonizations and infections within a hospital, but current control strategies focus only on preventing transmission from symptomatic carriers. Our objective was to evaluate the potential effectiveness of methods targeting asymptomatic carriers to control C. difficile colonization and infection (CDI) rates in a hospital ward: screening patients at admission to detect asymptomatic C. difficile carriers and placing positive patients into contact precautions. We developed an agent-based transmission model for C. difficile that incorporates screening and contact precautions for asymptomatic carriers in a hospital ward. We simulated scenarios that vary according to screening test characteristics, colonization prevalence, and type of strain present at admission. In our baseline scenario, on average, 42% of CDI cases were community-onset cases. Within the hospital-onset (HO) cases, approximately half were patients admitted as asymptomatic carriers who became symptomatic in the ward. On average, testing for asymptomatic carriers reduced the number of new colonizations and HO-CDI cases by 40%-50% and 10%-25%, respectively, compared with the baseline scenario. Test sensitivity, turnaround time, colonization prevalence at admission, and strain type had significant effects on testing efficacy. Testing for asymptomatic carriers at admission may reduce both the number of new colonizations and HO-CDI cases. Additional reductions could be achieved by preventing disease in patients who are admitted as asymptomatic carriers and developed CDI during the hospital stay.

    Few studies have investigated the associations between ambient air pollution and mental disorders (MDs), especially in developing countries. We conducted a time-series study to explore the associations between six criteria air pollutants and daily hospital admissions for MDs in Shanghai, China, from 2013 to 2015. The MDs data were derived from the Shanghai Health Insurance System. We used over-dispersed, generalized additive models to estimate the associations after controlling for time trend, weather conditions, day of the week, and holidays. In addition, we evaluated the effect of modification by age, sex, and season. A total of 39,143 cases of hospital admissions for MDs were identified during the study period. A 10-μg/m 3 increase in 2-day, moving-average concentration of inhalable particulate matter, sulfur dioxide (SO 2 ), and carbon monoxide was significantly associated with increments of 1.27% [95% confidence interval (CI): 0.28%, 2.26%], 6.88% (95% CI, 2.75%, 11.00%), and 0.16% (95% CI: 0.02%, 0.30%) in daily hospital admissions for MDs, respectively. We observed positive but insignificant associations of fine particulate matter, nitrogen dioxide and ozone. The estimated association of SO 2 was relatively robust to the adjustment of simultaneous exposure to other pollutants. We found generally stronger associations of air pollutants with MDs in warm seasons than in cool seasons. There were no significant differences in the associations between different sex and age groups. This study suggested that short-term exposure to air pollution, especially to sulfur dioxide, was associated with increased risk of hospital admissions for MDs in Shanghai, China.

    Elevated mortality associated with high ambient temperatures in summer represents one of the main impacts of weather extremes on human society. Increases in mortality during heat waves were examined in many European countries; much less is known about the effects of heat waves on morbidity, measured for example by the number of hospital admissions. Relatively less understood is also cold-related mortality and morbidity in winter, when the relationships between weather and human health are more complex, less direct, and confounded by other factors such as epidemics of influenza/acute respiratory infections. The present study examines links between hot and cold temperature extremes and daily hospital admissions for cardiovascular diseases in the population of the Czech Republic over 1994-2007. We make use of a recently completed database of all admissions for cardiovascular diseases to hospitals in the area of the Czech Republic since 1994, with a detailed classification of diseases and detailed information concerning each patient (in total 1,467,675 hospital admissions over 1994-2007). The main goals of the study are (i) to identify excess/deficit morbidity during and after periods of heat waves in summer and cold spells in winter, (ii) to compare the links for individual diseases (e.g. acute myocardial infarction, I21; angina pectoris, I20; cerebral infarction, I63; brain ischemia, I64) and to identify those diagnoses that are most closely linked to weather, (iii) to identify population groups most vulnerable to temperature extremes, and (iv) to compare the links to temperature extremes for morbidity and mortality. Periods when morbidity data were affected by epidemics of influenza and acute respiratory infections in winter were excluded from the analysis.

    Background: Many epidemiological studies have linked daily counts of hospital admissions to particulate matter (PM) with an aerodynamic diameter ≤ 10 μm (PM10) and ≤ 2.5 μm (PM2.5), but relatively few have investigated the relationship of hospital admissions with coarse PM (PMc; 2.5–10 μm aerodynamic diameter). Objectives: We conducted this study to estimate the health effects of PMc on emergency hospital admissions for respiratory diseases in Hong Kong after controlling for PM2.5 and gaseous pollutants. Methods: We conducted a time-series analysis of associations between daily emergency hospital admissions for respiratory diseases in Hong Kong from January 2000 to December 2005 and daily PM2.5 and PMc concentrations. We estimated PMc concentrations by subtracting PM2.5 from PM10 measurements. We used generalized additive models to examine the relationship between PMc (single- and multiday lagged exposures) and hospital admissions adjusted for time trends, weather conditions, influenza outbreaks, PM2.5, and gaseous pollutants (nitrogen dioxide, sulfur dioxide, and ozone). Results: A 10.9-μg/m3 (interquartile range) increase in the 4-day moving average concentration of PMc was associated with a 1.94% (95% confidence interval: 1.24%, 2.64%) increase in emergency hospital admissions for respiratory diseases that was attenuated but still significant after controlling for PM2.5. Adjusting for gaseous pollutants and altering models assumptions had little influence on PMc effect estimates. Conclusion: PMc was associated with emergency hospital admissions for respiratory diseases in Hong Kong independent of PM2.5 and gaseous pollutants. Further research is needed to evaluate health effects of different components of PMc. PMID:22266709

    STUDY OBJECTIVES--The aim was to explore the pattern of disease in staff associated with a bomber that crashed in 1968 when carrying nuclear bombs. DESIGN--The database was constructed from staff files of Danish workers employed from 1 April 1963 to 1 July 1971. Comparison was made between subsequent mortality and hospital admissions of workers employed during the clean up of the crashed bomber, and those employed outside this period. SETTING--The study involved workers employed at Thule US air base in Greenland. MAIN RESULTS--During 1963-1971, 4322 staff were employed at the air base. Of these, 4265 (98.7%) were identified in 1987, among whom 1202 workers were employed during the clean up period. No differences were found in total mortality, or mortality from cancer, heart disease, or accidents, after allowing for differences in age, marital status, or length of employment, between those employed during the clean up period and those employed at other times. Similarly, no difference in hospital admissions between the two groups was found. CONCLUSIONS--No harmful effects on health due to the crash were found, as measured by mortality and hospital admissions. PMID:1431702

    To evaluate the short-term effect of ambient air pollution on cardiovascular hospital admissions and capture the susceptible subpopulations in Wuhan, China, we adopted a generalized additive model to quantitatively analyze the influences of air pollutants on daily cardiovascular diseases hospital admissions and examine the influences of different subgroups. The largest significant effects for PM2.5, SO2 and NO2 on cardiovascular hospital admissions were observed at lag0, lag02 and lag02, respectively, and a 10μg/m3 increment in concentration of PM2.5, SO2 and NO2 were associated with 0.87% (95%CI: 0.05%-1.7%), 3.41% (95%CI: -0.21%-7.17%) and 2.98% (95%CI: 0.66%-5.37%) increases in cardiovascular hospital admissions. Nearly linear relationships were found for NO2 and PM2.5 with cardiovascular hospital admissions, and the J-shaped exposure-response relationship was observed for SO2 with cardiovascular hospital admissions. NO2 might have independent health effects of PM2.5 on the population at risk. The effect estimates for PM2.5 and SO2 were not sensitive with the inclusion of the co-pollutant adjustment. The gender, age and seasonal specific association between three pollutants and cardiovascular disease didn't show obvious differences in the magnitude and trend of the effects except that the seasonal difference of SO2 was significant. This study showed that PM2.5 and NO2 had effects on cardiovascular diseases, and the multiple pollutants should be considered together in the hazard models. In addition, the government should remind the resident to protect themselves and wear masks to avoid the harmful effect of air pollution, especially for the susceptible population.

    Hypothermia at hospital admission has been found to independently predict increased mortality in trauma patients. Objectives To establish if patients anaesthetised in the prehospital phase of care had a higher rate of hypothermia than non-anaesthetised patients on admission to hospital. Retrospective review of admission body temperature in 1292 consecutive prehospital trauma patients attended by a physician-led prehospital trauma service admitted to The Royal London Hospital between 1 July 2005 and 31 December 2008. 38% had a temperature recorded on admission. There was a significant difference in body temperature between the anaesthetised group (N=207) and the non-anaesthetised group (N=287): mean (SD) 35.0 (2.1) vs 36.2 (1.0)°C, respectively (p<0.001). No significant seasonal body temperature variation was demonstrated. This study confirmed that patients anaesthetised in the prehospital phase of care had a significantly lower admission body temperature. This has led to a change in the author's prehospital practice. Anaesthetised patients are now actively surface heated and have whole body insulation to prevent further heat loss in an attempt to conserve body temperature and improve outcome. This is an example of best in-hospital anaesthetic practice being carried out in the prehospital phase.

    Incidence of headaches across different regions and its relationship to unemployment rates in the United States before and during an economic recession was evaluated. Years 2008 and 2009 were determined as recessionary period. Headache-related admissions, particularly the uncomplicated headaches, increased significantly during recession. Proportion of women with headaches has increased and the age group of 25-54 years was the most affected during the recession. The hospital charges have increased even though the average length and charge of stay decreased. These findings are consistent with our understanding of effects of stress and unemployment on psychological and physical health.

    The day hospital is an alternative to hospitalization. This alternative improves accessibility and comfort of the patients, and avoids hospitalizations. Nevertheless, the efficacy of the polyvalent medical day hospital in avoiding hospitalizations has not been evaluated. To analyze hospital stays avoided by the polyvalent medical day hospital of a university hospital of the Andalusian Health Service. An observational prospective study of the patients studied and/or treated in the polyvalent medical day hospital of the Hospital Universitario Puerto Real over a one year period. A total of 9640 patients were attended to, with 1413 procedures and 4921 i.v. treatments. There were 3182 visits to the priority consultation of the polyvalent medical day hospital. The most frequent consultation complaints were constitutional symptoms (15.9%) and anemia (14.5%). After the first visit, 21.5% of the patients were discharged and fewer than 3% were hospitalized. Hospitalization was avoided in 16.8% of the patients, there being a 6.0% decrease in the need for hospital beds (5.0% reduction in the internal medicine unit). Inadequate hospitalizations and 30-day readmissions decreased 93.3% and 4.2%, respectively. The most frequent diagnosis was neoplasm (26.0%), and most of the beds freed up were generated by patients diagnosed of neoplasm (26.7%). With this type of polyvalent medical day hospital, we have observed improved efficiency of health care, freeing up hospital beds by reducing hospitalizations, inadequate hospitalizations and re-admissions in the medical units involved.

    Mortality and rehospitalizations still remain high after discharge for an acute cardiologic event. In this context, hospital discharge represents a potential pitfall for heart disease patients. In the setting of care transitions, the discharge letter is the main instrument of communication between hospital and primary care. Communication, besides, is an integral part of high-quality, patient-centered interventions aimed at improving the discharge process. Inadequate information at discharge significantly affects the quality of treatment compliance and the adoption of lifestyle modifications for an effective secondary prevention. The Health Department of Sicily, in 2013, established a task force with the aim to elaborate "Regional recommendations for hospital discharge and communication with patients after admission due to a cardiologic event", inviting to participate GICR-IACPR and many other scientific societies of cardiology and primary care, as discharge letter and communication are fundamental junctions of care transitions in cardiology. These recommendations have been published as a specific decree and contain: a structured model of discharge letter, which includes all of the parameters characterizing patients at high clinical risk, high thrombotic risk and low risk according to the Consensus document ANMCO/GICR-IACPR/GISE; is thus possible to identify these patients, choosing consequently the most appropriate follow-up pathways. A particular attention has been given to the "Medication Reconciliation" and to the identification of therapeutic targets; an educational Kit, with different forms on cardiac diseases, risk factors, drugs and lifestyle; a check-list about information given to the patient and caregivers. The "Recommendations" represent, in conclusion, the practical realization of the fruitful cooperation between scientific societies and political-administrative institutions that has been realized in Sicily in the last years.

    Although several studies have identified factors which increase the risk of heat-related illness, few have assessed the contribution of medicines. To address this knowledge gap, our study aimed to assess the risk of hospital admission for dehydration or other heat-related illness following initiation of medicines. We conducted a retrospective analysis using prescription event symmetry analysis (PESA) of 6700 veterans with incident hospital admission for dehydration or heat-related illness (ICD-10-AM codes E86, X30, T67), between 1 January 2001 and 30 June 2013. The main outcome measure was first ever hospital admission for dehydration or heat-related illness following initiation of commonly used medicines. A significantly higher risk of incident hospital admission for dehydration or heat-related illness was observed following initiation of anticoagulants, cardiovascular medicines, NSAIDs, antipsychotics, antidepressants and anticholinergic agents. The risk of hospital admission for dehydration or heat-related illness ranged from 1·17 (SSRIs) to 2·79 (ACEI plus diuretic combination product). No significant association was observed between initiation of anticonvulsants, anti-Parkinson's agents, hypnotics, anxiolytics or antihistamines and hospital admission for dehydration or heat-related illness. Many commonly used medicines were found to be associated with increased risk of hospitalization for dehydration or heat-related illness. Initiation of ACE inhibitors in combination with diuretics had the highest risk. Prescribers and patients should be aware of the potential for medicines to be associated with increased risk of dehydration and heat-related illness. © 2016 John Wiley & Sons Ltd.

    Pesticide self-poisoning causes one third of global suicides. Sri Lanka halved its suicide rate by banning WHO Class I organophosphorus (OP) insecticides and then endosulfan. However, poisoning with Class II toxicity OPs, particularly dimethoate and fenthion, remains a problem. We aimed to determine the effect and feasibility of a ban of the two insecticides in one Sri Lankan district. Sale was banned in June 2003 in most of Polonnaruwa District, but not Anuradhapura District. Admissions with pesticide poisoning to the district general hospitals was prospectively recorded from 2002. Hospital admissions for dimethoate and fenthion poisoning fell by 43% after the ban in Polonnaruwa, while increasing by 23% in Anuradhapura. The pesticide case fatality fell from 14.4% to 9.0% in Polonnaruwa (odds ratio [OR] 0.59, 95% confidence interval [CI] 0.41-0.84) and 11.3% to 10.6% in Anuradhapura (OR 0.93, 95%CI 0.70-1.25; p = 0.051). This reduction was not sustained, with case fatality in Polonnaruwa rising to 12.1% in 2006-2007. Further data analysis indicated that the fall in case fatality had actually been due to a coincidental reduction in case fatality for pesticide poisoning overall, in particular for paraquat poisoning. We found that the insecticides could be effectively banned from agricultural practice, as shown by the fall in hospital admissions, with few negative consequences. However, the ban had only a minor effect on pesticide poisoning deaths because it was too narrow. A study assessing the agricultural and health effects of a more comprehensive ban of highly toxic pesticides is necessary to determine the balance between increased costs of agriculture and reduced health care costs and fewer deaths.

    The demand for inpatient medical services increases during influenza season. A scoring system capable of identifying influenza patients at low risk death or ICU admission could help clinicians make hospital admission decisions. Hospitalized patients with laboratory confirmed influenza were identified over 3 influenza seasons at 25 Ontario hospitals. Each patient was assigned a score for 6 pneumonia severity and 2 sepsis scores using the first data available following their registration in the emergency room. In-hospital mortality and ICU admission were the outcomes. Score performance was assessed using the area under the receiver operating characteristic curve (AUC) and the sensitivity and specificity for identifying low risk patients (risk of outcome <5%). The cohort consisted of 607 adult patients. Mean age was 76 years, 12% of patients died (71/607) and 9% required ICU care (55/607). None of the scores examined demonstrated good discriminatory ability (AUC>or=0.80). The Pneumonia Severity Index (AUC 0.78, 95% CI 0.72-0.83) and the Mortality in Emergency Department Sepsis score (AUC 0.77, 95% 0.71-0.83) demonstrated fair predictive ability (AUC>or=0.70) for in-hospital mortality. The best predictor of ICU admission was SMART-COP (AUC 0.73, 95% CI 0.67-0.79). All other scores were poor predictors (AUC <0.70) of either outcome. If patients classified as low risk for in-hospital mortality using the PSI were discharged, 35% of admissions would have been avoided. None of the scores studied were good predictors of in-hospital mortality or ICU admission. The PSI and MEDS score were fair predictors of death and if these results are validated, their use could reduce influenza admission rates significantly.

    Background: Epidemiological research has shown that mortality increases during hot weather and heat waves, but little is known about the effect on non-fatal outcomes in the UK. Aims and Methods: The effects of hot weather and heat waves on emergency hospital admissions were investigated in Greater London, UK, for a range of causes and age groups. Time series analyses were conducted of daily emergency hospital admissions, 1 April 1994 to 31 March 2000, using autoregressive Poisson models with adjustment for long term trend, season, day of week, public holidays, the Christmas period, influenza, relative humidity, air pollution (ozone, PM10), and overdispersion. The effects of heat were modelled using the average of the daily mean temperature over the index and previous two days. Results: There was no clear evidence of a relation between total emergency hospital admissions and high ambient temperatures, although there was evidence for heat related increases in emergency admissions for respiratory and renal disease, in children under 5, and for respiratory disease in the 75+ age group. During the heat wave of 29 July to 3 August 1995, hospital admissions showed a small non-significant increase: 2.6% (95% CI –2.2 to 7.6), while daily mortality rose by 10.8% (95% CI 2.8 to 19.3) after adjusting for time varying confounders. Conclusions: The impact of hot weather on mortality is not paralleled by similar magnitude increases in hospital admissions in the UK, which supports the hypothesis that many heat related deaths occur in people before they come to medical attention. This has evident implications for public health, and merits further enquiry. PMID:15477282

    The health impacts of wildfire smoke, including fine particles (PM2.5), are not well understood and may differ from those of PM2.5 from other sources due to differences in concentrations and chemical composition. First, for the entire Western United States (561 counties) for 2004-2009, we estimated daily PM2.5 concentrations directly attributable to wildfires (wildfires-specific PM2.5), using a global chemical transport model. Second, we defined smoke wave as ≥2 consecutive days with daily wildfire-specific PM2.5 > 20 μg/m, with sensitivity analysis considering 23, 28, and 37 μg/m. Third, we estimated the risk of cardiovascular and respiratory hospital admissions associated with smoke waves for Medicare enrollees. We used a generalized linear mixed model to estimate the relative risk of hospital admissions on smoke wave days compared with matched comparison days without wildfire smoke. We estimated that about 46 million people of all ages were exposed to at least one smoke wave during 2004 to 2009 in the Western United States. Of these, 5 million are Medicare enrollees (≥65 years). We found a 7.2% (95% confidence interval: 0.25%, 15%) increase in risk of respiratory admissions during smoke wave days with high wildfire-specific PM2.5 (>37 μg/m) compared with matched non smoke wave days. We did not observe an association between smoke wave days with wildfire-specific PM2.5 ≤ 37 μg/mand respiratory or cardiovascular admissions. Respiratory effects of wildfire-specific PM2.5 may be stronger than that of PM2.5 from other sources. Short-term exposure to wildfire-specific PM2.5was associated with risk of respiratory diseases in the elderly population in the Western United States during severe smoke days.

    Amyotrophic lateral sclerosis is a progressive disease with rapid degeneration. Respite care is an essential service for improving the well-being of both patients with this disease and their family caregivers, but accessibility of respite services is limited. This study investigates perspectives on respite admission among people living with amyotrophic lateral sclerosis and the hospitals supporting them. We conducted semistructured interviews among 3 patients with amyotrophic lateral sclerosis and 12 family members, exploring demographic information and their awareness and experience of respite admission. We also interviewed 16 representatives from hospitals about awareness of and preparation for respite admission for patients with this disease, the role of regional networks for intractable diseases, and knowledge about communication support schemes. We found significant differences in the revised Amyotrophic Lateral Sclerosis Functional Rating Scale between patients who had and had not received respite admission. Qualitative analysis of the data indicated that respite admission was a contributory factor in continuing and stabilizing home care. Limited provision of social services and hospital care quality were barriers to respite admission. Respite admission was essential to continued home care for patients with amyotrophic lateral sclerosis. Severe-stage patients were eligible for respite admission. Its accessibility, however, was limited, especially for patients living in rural areas. Supporting hospitals had limited capacity to respond to patients' needs. Individualized care and communication were internal barriers to respite admission.

    To measure the appropriateness of hospital admissions, to classify its Clinical Services (CS) according to the level of inappropriateness, and to determine the usefulness of applying rapid assessment techniques (lot quality assurance sampling) in these types of measurements. A descriptive, retrospective study was conducted in a tertiary hospital to assess the clinical records of emergency admissions to the 12 CS with a higher volume of admissions, using the Appropriateness Evaluation Protocol (AEP). A four-level («A» to «D») increasingly inadequate admissions scale was constructed setting both standard and threshold values in every stratum. Every CS was classified in one of them using lot quality assurance sampling (LQAS). A total of 156 cases (13 cases from every CS) were assessed. The assessment effort (devoted time) was also estimated. There were 22.4±6.3% of inadequate admissions. In the CS classification, 9 (75%) got a good or acceptable appropriateness level, and only 1 (8%) got an inacceptable level. The time devoted was estimated at 17 hours. AEP is useful to assess the admission appropriateness and may be included in the «Emergencies» process management, although its variability prevents the use for external comparisons. If both LQAS and the appropriateness classification level and the global estimation (by unifying lot samples) are combined, the monitoring is affordable without a great effort. To extend these tools to other quality indicators requiring direct observation or clinical records, manual assessment could improve the monitoring efficiency. Copyright © 2013 SECA.

    A survey of U.S. pediatric training programs to determine the role of rules in the hospital admission of pediatric patients is reported. The results support the hypothesis that rules are a widely used teaching tool. The rules relate to such factors as fevers, age, specific diseases, administrative concerns, head traumas, and poisonings. (JMD)

    A substantial reduction in bacterial meningitis has occurred in the UK following successful implementation of immunisation programmes. Most childhood meningitis in developed countries is now caused by viruses. Long-term trends in paediatric viral meningitis in England have not previously been reported. The objective of this study is to report on epidemiological trends over time in childhood viral meningitis in England. In this population-based observational study, we used routinely collected hospital discharge records from English National Health Service hospitals from 1968-2011 to analyse annual age-specific admission rates for viral meningitis, including specific viral aetiologies, in children younger than 15 years. We analysed hospital discharge records from Jan 1, 1968, to Dec 31, 2011. Hospital admission rates for viral meningitis from Jan 1, 1968, to Dec 31, 1985, varied annually, with a mean of 13·5 admissions per 100 000 children aged less than 15 years, per year (95% CI 13·0-14·0). Admission rates declined during the late 1980s, and the mean number of admissions from 1989-2011 was 5·2 per 100 000 per year (5·1-5·3). This decrease was entirely in children aged 1-14 years. Admission rates for infants aged less than 1 year increased since 2005, to 70·0 per 100 000 (63·7-76·2) in 2011, which was driven by an increase in admission of infants aged 90 days or less. In 1968-85, the majority of cases in children were in those aged 1-14 years (22 150 [89%] of 24 920 admissions). In 2007-11, 1716 (72%) of 2382 cases were in infants. Admissions for mumps-related meningitis almost disappeared following introduction of the measles-mumps-rubella (MMR) vaccine in 1988. Admissions with a specified viral aetiology have increased since 2000. Trends in viral meningitis admissions have changed substantially over the past 50 years, and probably reflect the impact of the MMR vaccine programme and the use of more sensitive diagnostic techniques.

    Ambient air pollution, is one of the most frequently stated environmental problems. Many epidemiological studies have documented adverse health effects for ambient air pollution. This study aimed to investigate the association between ambient air pollution and respiratory hospital admissions. In this ecological time series study data about air pollutant concentrations including CO, NO 2 , O 3 , PM 2.5 , PM 10 and SO 2 and, respiratory hospital admissions in the urban population of Arak, from January 1st 2010 to December 31st 2015; were inquired, from the Arak Department of Environment, and two major hospitals, respectively. Meteorological data were inquired for the same period as well. Time-series regression analysis with a distributed lag model, controlled for seasonality long-time trends, weather and day of the week, was used for data analysis. Every 10 μg/m 3 increase in NO 2 , and PM 10 and every 1 mg/m 3 increase in CO at lag 0 corresponded to a RR = 1.032 (95%CI, 1.003-1.06), RR = 1.01 (95%CI, 1.004-1.017) and RR = 1.09 (95%CI, 1.04-1.14), increase in respiratory disease hospitalizations, respectively. Males and the elderly were found to be more susceptible than females and other age groups to air pollutants in regard to respiratory disease admissions. The results of this study showed that outdoor air pollutants significantly increase respiratory hospital admissions; especially among the men and elders in Arak.

    Climate forecasts predict an increase in frequency and intensity of wildfires. Associations between health outcomes and population exposure to smoke from Washington 2012 wildfires were compared using surface monitors, chemical-weather models, and a novel method blending three exposure information sources. The association between smoke particulate matter ≤2.5 μm in diameter (PM2.5) and cardiopulmonary hospital admissions occurring in Washington from 1 July to 31 October 2012 was evaluated using a time-stratified case-crossover design. Hospital admissions aggregated by ZIP code were linked with population-weighted daily average concentrations of smoke PM2.5 estimated using three distinct methods: a simulation with the Weather Research and Forecasting with Chemistry (WRF-Chem) model, a kriged interpolation of PM2.5 measurements from surface monitors, and a geographically weighted ridge regression (GWR) that blended inputs from WRF-Chem, satellite observations of aerosol optical depth, and kriged PM2.5. A 10 μg/m3 increase in GWR smoke PM2.5 was associated with an 8% increased risk in asthma-related hospital admissions (odds ratio (OR): 1.076, 95% confidence interval (CI): 1.019–1.136); other smoke estimation methods yielded similar results. However, point estimates for chronic obstructive pulmonary disease (COPD) differed by smoke PM2.5 exposure method: a 10 μg/m3 increase using GWR was significantly associated with increased risk of COPD (OR: 1.084, 95%CI: 1.026–1.145) and not significant using WRF-Chem (OR: 0.986, 95%CI: 0.931–1.045). The magnitude (OR) and uncertainty (95%CI) of associations between smoke PM2.5 and hospital admissions were dependent on estimation method used and outcome evaluated. Choice of smoke exposure estimation method used can impact the overall conclusion of the study. PMID:28868515

    Climate and weather conditions are the most important factors that influence activities and human health. Bioclimatology/biometeorology are concerned with the study of weather effects on living creatures, including humans, plants, and animals. This research was prepared in order to understand the bioclimatic condition of Kermanshah and its relation to the level of hospital admissions of cardiovascular patients in this city. In addition to the climatic variables, the statistics on the number of daily admissions of cardiovascular patients in Kermanshah during March 27, 2009 to April 30, 2015 was prepared. First, Kermanshah's bioclimatic conditions were identified on a daily basis. Then, the relationship between each of the thermal sensations with the level of hospital admissions of cardiovascular patients in Kermanshah using Levene's test, univariate analysis of variance (ANOVA), Scheffe and Games-Howell post hoc tests was investigated. The results of this study showed that in each index, only very few bioclimatic conditions have had an impact on the increase of hospital admissions of cardiovascular diseases. For example, based on the equivalent temperature index (Tek or EqT), there is a significant relationship between extreme conditions and the rate of cardiovascular admissions. But, however, in the effective temperature index (TE), a significant correlation between warm/hot conditions and an increase in the number of cardiovascular admissions was seen. Based on the predicted mean vote (PMV) and physiological equivalent temperature (PET) indices, cool and cold conditions more than warm and comfort conditions have an effect on the number of hospital admissions of cardiovascular patients. Overall, the obtained results showed that the extreme climatic conditions were directly related to an increase in cardiovascular disease in Kermanshah.

    The link between various pathologies and atmospheric conditions has been a constant topic of study over recent decades in many places across the world; knowing more about it enables us to pre-empt the worsening of certain diseases, thereby optimizing medical resources. This study looked specifically at the connections in winter between respiratory diseases and types of atmospheric weather conditions (Circulation Weather Types, CWT) in Galicia, a region in the north-western corner of the Iberian Peninsula. To do this, the study used hospital admission data associated with these pathologies as well as an automatic classification of weather types. The main result obtained was that weather types giving rise to an increase in admissions due to these diseases are those associated with cold, dry weather, such as those in the east and south-east, or anticyclonic types. A second peak was associated with humid, hotter weather, generally linked to south-west weather types. In the future, this result may help to forecast the increase in respiratory pathologies in the region some days in advance.

    To evaluate whether the Hospital Admission Risk Profile (HARP) score is associated with skilled nursing or acute rehabilitation facility discharge after an acute hospitalization. Retrospective cohort study. Inpatient unit of a rural academic medical center. Hospitalized individuals aged 70 and older from October 1, 2013 to June 1, 2014. Participant age at the time of admission, modified Folstein Mini-Mental State Examination score, and self-reported instrumental activities of daily living 2 weeks before admission were used to calculate HARP score. The primary predictor was HARP score, and the primary outcome was discharge disposition (home, facility, deceased). Multivariate analysis was used to evaluate the association between HARP score and discharge disposition, adjusting for age, sex, comorbidities, and length of stay. Four hundred twenty-eight individuals admitted from home were screened and their HARP scores were categorized as low (n = 162, 37.8%), intermediate (n = 157, 36.7%), or high (n = 109, 25.5%). Participants with high HARP scores were significantly more likely to be discharged to a facility (55%) than those with low HARP scores (20%) (P < .001). After adjustment, participants with high HARP scores were more than four times as likely as those with low scores to be discharged to a facility (odds ratio = 4.58, 95% confidence interval = 2.42-8.66). In a population of older hospitalized adults, HARP score (using readily available admission information) identifies individuals at greater risk of skilled nursing or acute rehabilitation facility discharge. Early identification for potential facility discharges may allow for targeted interventions to prevent functional decline, improve informed shared decision-making about post-acute care needs, and expedite discharge planning. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

  8. An increase in the burden of neonatal admissions to a rural district hospital in Kenya over 19 years

    PubMed Central

    2010-01-01

    Background Most of the global neonatal deaths occur in developing nations, mostly in rural homes. Many of the newborns who receive formal medical care are treated in rural district hospitals and other peripheral health centres. However there are no published studies demonstrating trends in neonatal admissions and outcome in rural health care facilities in resource poor regions. Such information is critical in planning public health interventions. In this study we therefore aimed at describing the pattern of neonatal admissions to a Kenyan rural district hospital and their outcome over a 19 year period, examining clinical indicators of inpatient neonatal mortality and also trends in utilization of a rural hospital for deliveries. Methods Prospectively collected data on neonates is compared to non-neonatal paediatric (≤ 5 years old) admissions and deliveries' in the maternity unit at Kilifi District Hospital from January 1st 1990 up to December 31st 2008, to document the pattern of neonatal admissions, deliveries and changes in inpatient deaths. Trends were examined using time series models with likelihood ratios utilised to identify indicators of inpatient neonatal death. Results The proportion of neonatal admissions of the total paediatric ≤ 5 years admissions significantly increased from 11% in 1990 to 20% by 2008 (trend 0.83 (95% confidence interval 0.45 -1.21). Most of the increase in burden was from neonates born in hospital and very young neonates aged < 7days. Hospital deliveries also increased significantly. Clinical diagnoses of neonatal sepsis, prematurity, neonatal jaundice, neonatal encephalopathy, tetanus and neonatal meningitis accounted for over 75% of the inpatient neonatal admissions. Inpatient case fatality for all ≤ 5 years declined significantly over the 19 years. However, neonatal deaths comprised 33% of all inpatient death among children aged ≤ 5 years in 1990, this increased to 55% by 2008. Tetanus 256/390 (67%), prematurity 554

    There is a paucity of data describing cardiovascular events after tornado outbreaks. We proposed to study the effects of tornadoes on the incidence of cardiovascular events at a tertiary care institution. Hospital admission records from a single center situated in a tornado-prone area three months before and after a 2013 tornado outbreak were abstracted. To control for seasonal variation, we also abstracted data from the same period of the prior year (control). Hospital admissions for cardiovascular events (CVEs) including acute myocardial infarction, stroke and venous thromboembolism (VTE) were summated by zip codes, and compared by time period. There were 22,607 admissions analyzed, of which 6,705 (30%), 7,980 (35%), and 7,922 (35%) were during the pre-tornado, post-tornado, and control time frames, respectively. There were 344 CVE in the controls, 317 CVE in pre-tornado and 364 CVEs in post tornado periods. There was no difference in the prevalence of CVE during the post-tornado season compared with the control (PPR=1.05 95% CI: 0.91 to 1.21, p=0.50) or the pre-tornado season (PPR=0.96, 95% CI: 0.83 to 1.21, p=0.63). In conclusion, tornado outbreaks did not increase the prevalence of cardiovascular events. In contrast to the effect of hurricanes, implementation of a healthcare policy change directed toward the early treatment and prevention of cardiovascular events after tornadoes does not seem warranted.

    Serious mental illness (SMI, including schizophrenia, schizoaffective disorder, and bipolar disorder) is associated with worse general health. However, admissions to general hospitals have received little investigation. We sought to delineate frequencies of and causes for non-psychiatric hospital admissions in SMI and compare with the general population in the same area. Records of 18 380 individuals with SMI aged ⩾20 years in southeast London were linked to hospitalisation data. Age- and gender-standardised admission ratios (SARs) were calculated by primary discharge diagnoses in the 10th edition of the World Health Organization International Classification of Diseases (ICD-10) codes, referencing geographic catchment data. Commonest discharge diagnosis categories in the SMI cohort were urinary conditions, digestive conditions, unclassified symptoms, neoplasms, and respiratory conditions. SARs were raised for most major categories, except neoplasms for a significantly lower risk. Hospitalisation risks were specifically higher for poisoning and external causes, injury, endocrine/metabolic conditions, haematological, neurological, dermatological, infectious and non-specific ('Z-code') causes. The five commonest specific ICD-10 diagnoses at discharge were 'chronic renal failure' (N18), a non-specific code (Z04), 'dental caries' (K02), 'other disorders of the urinary system' (N39), and 'pain in throat and chest' (R07), all of which were higher than expected (SARs ranging 1.57-6.66). A range of reasons for non-psychiatric hospitalisation in SMI is apparent, with self-harm, self-neglect and/or reduced healthcare access, and medically unexplained symptoms as potential underlying explanations.

    This study investigated the short-term effects of temperature on out-patient visits and hospital admissions in Chiang Mai, Thailand. While mortality outcomes in the literature have been reported, there is less evidence of morbidity effects with very few studies conducted in developing countries with subtropical or tropical climate. Time-series regression analysis was employed using generalized negative binomial regression to model the short-term relationships between temperature and morbidity after controlling for seasonal patterns and other potential confounders. Lag effects up to 13 days and effect modification by age (0-14 years, 15-64 years, ≥65 years) were examined. Temperature effects with wide confidence intervals were found, with an increase in diabetic visits of 26.3% (95% CI: 7.1%-49.0%), and circulatory visits of 19.2% (95% CI: 7.0%-32.8%) per 1 °C increase in temperature above an identified threshold of 29 °C. Additionally, there was a rise of both visits (3.7% increase, 95% CI: 1.5%-5.9%) and admissions (5.8% increase, 95% CI: 2.3%-9.3%) due to intestinal infectious disease in association with each 1 °C increase across the whole temperature range. The effects of temperature were stronger in the elderly though not statistically significant. Daily morbidity in Chiang Mai was positively associated with temperature with a lag effect of up to 2 weeks, which was longer than lag effects previously reported. Public health preparedness and interventions should be considered to minimise possible increased hospital visits and admissions during hot weather. Copyright © 2011 Elsevier B.V.

    Most previous studies have focused on the association between acute myocardial function (AMI) and temperature by gender and age. Recently, however, concern has also arisen about those most susceptible to the effects of temperature according to socioeconomic status (SES). The objective of this study was to determine the effect of heat and cold on hospital admissions for AMI by subpopulations (gender, age, living area, and individual SES) in South Korea. The Korea National Health Insurance (KNHI) database was used to examine the effect of heat and cold on hospital admissions for AMI during 2004–2012. We analyzed the increase in AMI hospital admissions both above and below a threshold temperature using Poisson generalized additive models (GAMs) for hot, cold, and warm weather. The Medicaid group, the lowest SES group, had a significantly higher RR of 1.37 (95% CI: 1.07–1.76) for heat and 1.11 (95% CI: 1.04–1.20) for cold among subgroups, while also showing distinctly higher risk curves than NHI for both hot and cold weather. In additions, females, older age group, and those living in urban areas had higher risks from hot and cold temperatures than males, younger age group, and those living in rural areas. PMID:26580643

    Objective: To evaluate clinical characteristics and outcomes in patients hospitalized for tuberculosis, comparing those in whom tuberculosis treatment was started within the first 24 h after admission with those who did not. Methods: This was a retrospective cohort study involving new tuberculosis cases in patients aged ≥ 18 years who were hospitalized after seeking treatment in the emergency room. Results: We included 305 hospitalized patients, of whom 67 (22.0%) received tuberculosis treatment within the first 24 h after admission ( ≤24h group) and 238 (88.0%) did not (>24h group). Initiation of tuberculosis treatment within the first 24 h after admission was associated with being female (OR = 1.99; 95% CI: 1.06-3.74; p = 0.032) and with an AFB-positive spontaneous sputum smear (OR = 4.19; 95% CI: 1.94-9.00; p < 0.001). In the ≤24h and >24h groups, respectively, the ICU admission rate was 22.4% and 15.5% (p = 0.258); mechanical ventilation was used in 22.4% and 13.9% (p = 0.133); in-hospital mortality was 22.4% and 14.7% (p = 0.189); and a cure was achieved in 44.8% and 52.5% (p = 0.326). Conclusions: Although tuberculosis treatment was initiated promptly in a considerable proportion of the inpatients evaluated, the rates of in-hospital mortality, ICU admission, and mechanical ventilation use remained high. Strategies for the control of tuberculosis in primary care should consider that patients who seek medical attention at hospitals arrive too late and with advanced disease. It is therefore necessary to implement active surveillance measures in the community for earlier diagnosis and treatment. PMID:25029651

    The study of the short-term effects and health impact of air pollution is carrier out by the ERPURS regional surveillance program which utilizes hospitalization data obtained from the French hospital information system (PMSI) to determine these links. This system does not permit the distinction between emergency hospital admissions from scheduled ones, which cannot be related to short term changes in air pollution levels. This study examines how scheduled admissions affect the quality of the health indicators used to estimate air pollution effects. This indicator is compared to three new emergency hospitalisation indicators reconstructed based on data from the public hospitals in Paris, partly from the PMSI data and partly with data from an on-line emergency network that regroups all of the computerized emergency services. According to the pathology, scheduled admissions present a difficulty which affects the capacity to highlight the weakest risks with any precision.

    An increasing number of surgical and nonsurgical procedures are being performed on an ambulatory basis in children. Analysis of a large group of pediatric patients with congenital heart disease undergoing ambulatory procedures has not been undertaken. The objective of this study was to characterize the profile of children with congenital heart disease who underwent noncardiac procedures on an ambulatory basis at our institution, to determine the incidence of adverse cardiovascular and respiratory adverse events, and to determine the risk factors for unscheduled hospital admission. This is a retrospective study of children with congenital heart disease who underwent noncardiac procedures on an ambulatory basis in a single center. Using the electronic preoperative anesthesia evaluation form, we identified 3010 patients with congenital heart disease who underwent noncardiac procedures of which 1028 (34.1%) were scheduled to occur on an ambulatory basis. Demographic, echocardiographic and functional status data, cardiovascular and respiratory adverse events, and reasons for postprocedure admission were recorded. Univariable analysis was conducted. The unplanned hospital admission was 2.7% and univariable analysis demonstrated that performance of an echocardiogram within 6 mo of the procedure and procedures performed in radiology were associated with postoperative admission. Cardiovascular adverse event incidence was 3.9%. Respiratory adverse event incidence was 1.8%. Ambulatory, noncomplex procedures can be performed in pediatric patients with congenital heart disease and good functional status with a relatively low unanticipated hospital admission rate. © 2018 John Wiley & Sons Ltd.

    Record linkage (RL) is the process of identifying pairs of records that correspond to the same entity, for example the same patient. The basic approach assigns to each pair of records a similarity weight, and then determines a certain threshold, above which the two records are considered to be a match. Three different RL methods were applied under privacy-preserving conditions on hospital admission data: deterministic RL (DRL), probabilistic RL (PRL), and Bloom filters. The patient characteristics like names were one-way encrypted (DRL, PRL) or transformed to a cryptographic longterm key (Bloom filters). Based on one year of hospital admissions, the data set was split randomly in 30 thousand new and 1,5 million known patients. With the combination of the three RL-methods, a positive predictive value of 83 % (95 %-confidence interval 65 %-94 %) was attained. Thus, the application of the presented combination of RL-methods seem to be suited for other applications of population-based research.

    Objective. Asthma education programs have been shown to decrease healthcare utilization and improve disease control and management. The purpose of our study was to evaluate the impact of an outpatient adult asthma education program in an inner city hospital caring for patients with low socioeconomic and educational status. Methods. An asthma education program was implemented in September 2014. Patients who received education from September 2014 to July 2015 were evaluated. Outcomes were compared for the same group of patients before and after education. Primary outcomes were emergency room (ER) visits and hospital admissions. Secondary outcomes were change in Asthma Control Test (ACT) score and number of pulmonary clinic visits. Results. Asthma education significantly decreased number of patients requiring ER visits and hospital admissions (p = 0.0005 and p = 0.0015, resp.). Asthma control as per ACT score ≥ 20 improved with education (p = 0.0001) with an increase in clinic visits (p = 0.0185). Conclusions. Our study suggests that implementation of a structured asthma education program in an inner city community hospital has a positive impact on reduction of ER visits and hospital admissions with improvement in asthma control.

    Managing people with diabetes is a health priority worldwide. Cost benefit attempts at avoiding non elective admissions (NEA) have had some success. To develop an NEA avoidance service, we audited multiple NEA in those with diabetes. All people with diabetes who had ≥3 NEA to our hospital over 12 months were identified (n=418); 104 (1 in 4) patients were randomly selected and retrospective data collected in 98 subjects on their index (latest, 3rd) admission. Of 98 subjects (50 males, 60 Caucasians, 86 type 2 diabetes, aged 69±16 years).Conditions contributing to admission included: Significant co-morbidities in 95 patients (≥2 in 57, ≥4 in 24). Only 14 admission were directly due to diabetes: hypoglycaemia (5); hyperglycaemia (6); DKA (2), Infected foot ulcer (1).97 admissions were justified at the time of presentation. However whilst 78 were unavoidable, 19 were deemed avoidable amongst whom 10 were diabetes related. The majority of re-admissions were due to multi-morbidity and were often non-diabetes related. The concept of avoidability must be distinguished from point justification at the time of acute need. This would allow the prospective identification of high risk patients and requires an integrated working process to avoid NEA. Copyright © 2015 Primary Care Diabetes Europe.

    Exposure to pollen can contribute to increased hospital admissions for asthma exacerbation. This study applied an ecological time series analysis to examine associations between atmospheric concentrations of different pollen types and the risk of hospitalization for asthma in London from 2005 to 2011. The analysis examined short-term associations between daily pollen counts and hospital admissions in the presence of seasonal and long-term patterns, and allowed for time lags between exposure and admission. Models were adjusted for temperature, precipitation, humidity, day of week, and air pollutants. Analyses revealed an association between daily counts (continuous) of grass pollen and adult hospital admissions for asthma in London, with a 4-5-day lag. When grass pollen concentrations were categorized into Met Office pollen 'alert' levels, 'very high' days (vs. 'low') were associated with increased admissions 2-5 days later, peaking at an incidence rate ratio of 1.46 (95%, CI 1.20-1.78) at 3 days. Increased admissions were also associated with 'high' versus 'low' pollen days at a 3-day lag. Results from tree pollen models were inconclusive and likely to have been affected by the shorter pollen seasons and consequent limited number of observation days with higher tree pollen concentrations. Future reductions in asthma hospitalizations may be achieved by better understanding of environmental risks, informing improved alert systems and supporting patients to take preventive measures.

    Falls are a major cause of morbidity and mortality in the elderly. This study examined the frequency of hospital admission for falls or fractures, and the association with a recent change in the use of cardiovascular and psychotropic medications. We conducted a retrospective case-cohort study of 39,813 patients aged >65 years from 40 Scottish general practices. Data on current prescriptions, dates of drug changes (defined as increases in dose or starting new drugs), diagnoses and clinical measurements were extracted from primary care electronic records, linked to national hospital admissions data. Multivariable logistic regression was used to model the association of change in prescribing of cardiovascular or psychotropic medication with admission to hospital for falls or fractures in the following 60 days. A total of 838 patients (2.1 %) were admitted in the 1-year study period. Following adjustment for factors including age, sex, socioeconomic deprivation, co-morbidity and current prescribing, changes in both cardiovascular and psychotropic medications were associated with subsequent admission for falls or fractures (odds ratio [OR] 1.54 [95 % confidence interval (CI) 1.17-2.03] and 1.68 [95 % CI 1.28-2.22], respectively). There was no evidence for a difference in the effect of change in medication for different cardiovascular drug types (p = 0.86), but there was evidence (p = 0.003) for variation in the association between change in different psychotropic medications and admission; the strongest associations were observed for changes in selective serotonin reuptake inhibitor (SSRI) antidepressants (OR 1.99 [95 % CI 1.29-3.08]), non-SSRI/tricyclic antidepressants (OR 4.39 [95 % CI 2.21-8.71]) and combination psychotropic medication (OR 3.05 [95 % CI 1.66-5.63]). Recent changes in psychotropic and cardiovascular medications are associated with a substantial increase in risk of hospital admission for falls and fractures. Caution should thus be taken when

    Lack of up-to-date information of hospitals beds, specifically in emergencies, is a significant problem in many large countries; The Ministry of Health and Medical Education of Iran (MOHME) designed and implemented a dynamic system that reports the status of beds in 2012. This system created great opportunities for national bed management, including real-time hospital admission monitoring, especially for emergency departments, ICUs and CCUs. Therefore, an additional online system was planned to be implemented for monitoring hospital admissions, including a national alert system. Prior to the design of this system, a study was done using literature study and expert opinion to investigate the advantages and features that this monitoring system was required to have. We used the MoSCoW method to prioritize the requirements of the system. This system was designed to have the following advantages, among other things: the hospitals as well as government should be able to track the patients, manage patient distribution in healthcare centers, and make policy for supplying extra beds. It should also be possible for the hospitals executive board, as well as the government, to monitor the performance of the hospitals regarding patient admissions (i.e., the rate of rejection of patients with severe conditions).

    Short-term exposure to air pollution can trigger hospital admissions for asthma in children, but it is not known which components of air pollution are most important. There are no available studies on the particular effect of ultrafine particles (UFPs) on paediatric admissions for asthma. To study whether short-term exposure to air pollution is associated with hospital admissions for asthma in children. It is hypothesised that (1) the association between asthma admissions and air pollution is stronger with UFPs than with coarse (PM10) and fine (PM2.5) particles, nitrogen oxides (NOx) or nitrogen dioxide (NO2); and (2) infants are more susceptible to the effects of exposure to air pollution than older children. Daily counts of admissions for asthma in children aged 0-18 years to hospitals located within a 15 km radius of the central fixed background urban air pollution measurement station in Copenhagen between 2001 and 2008 were extracted from the Danish National Patient Registry. A time-stratified case crossover design was applied and data were analysed using conditional logistic regression to estimate the effect of air pollution on asthma admissions. A significant association was found between hospital admissions for asthma in children aged 0-18 years and NOx (OR 1.11; 95% CI 1.05 to 1.17), NO2 (1.10; 95% CI 1.04 to 1.16), PM10 (1.07; 95% CI 1.03 to 1.12) and PM2.5 (1.09; 95% CI 1.04 to 1.13); there was no association with UFPs. The association was stronger in infants than in older children for all pollutants, but no statistically significant interaction was detected. Short-term exposure to air pollution can trigger hospital admission for asthma in children, with infants possibly being most susceptible. These effects seemed to be mediated by larger particles and traffic-related gases, whereas UFPs showed no effect.

    Previous studies have shown that children with isolated linear skull fractures have excellent clinical outcomes and low risk of surgery. We wish to identify other injury patterns within the spectrum of paediatric mild head injury, which need only conservative management. Children with low risk of evolving neurosurgical lesions could be safely managed in primary hospitals. We retrospectively analysed all children with mild head injury (i.e. admission Glasgow coma score 13-15) and skull fracture or haematoma on a head computed tomography scan admitted to Westmead Children's Hospital, Sydney over the years 2009-2014. Data were collected regarding demographics, clinical findings, mechanism of injury, head computed tomography scan findings, neurosurgical intervention, outcome and length of admission. Wilcoxon paired test was used with P value <0.05 considered significant. Four hundred and ten children were analysed. Three hundred and eighty-one (93%) children were managed conservatively, 18 (4%) underwent evacuation of extradural haematoma (TBI surgery) and 11 (3%) needed fracture repair surgery. Two children evolved a surgical lesion 24 h post-admission. Only 17 of 214 children transferred from peripheral hospitals needed neurosurgery. Overall outcomes: zero deaths, one needed brain injury rehabilitation and 63 needed child protection unit intervention. Seventy-five percentage of children with non-surgical lesions were discharged within 2 days. Eighty-three percentage of road transfers were discharged within 3 days. Children with small intracranial haematomas and/or skull fractures who need no surgery only require brief inpatient symptomatic treatment and could be safely managed in primary hospitals. Improved tertiary hospital transfer guidelines with protocols to manage clinical deterioration could have cost benefit without risking patient safety. © 2017 Royal Australasian College of Surgeons.

    Acute diarrheal disease is the second cause of death in children under 5 years. In Brazil, from 2003 to 2009, acute diarrhea was responsible for nearly 100,000 hospital admissions per year and 4% of the deaths in children under 5 years. Rotavirus is the leading cause of severe acute diarrhea worldwide. In 2006, the rotavirus monovalent vaccine (RV1) was added to the Brazilian National Immunization Program. To analyze the impact of the RV1 on emergency department (ED) visits and hospital admissions for acute diarrhea. A retrospective ecologic study at the University Hospital, University of São Paulo. The study analyzed the pre-vaccine (2003-2005) and the post-vaccine (2007-2009) periods. We screened the main diagnosis of all ED attendances and hospital admissions of children under 5 years in an electronic registry system database and calculated the rates of ED visits and hospital admissions. The reduction rate was analyzed according to the following formula: reduction (%) = (1 - odds ratio) x 100. The rates of ED visits for acute diarrhea was 85.8 and 80.9 per 1,000 total ED visits in the pre and post vaccination periods, respectively, resulting in 6% reduction (95CI 4 to 9%, p<0.001). The rates of hospital admissions for acute diarrhea was 40.8 per 1,000 in the pre-vaccine period and dropped to 24.9 per 1,000 hospitalizations, resulting in 40% reduction (95CI 22 to 54%, p<0.001). The introduction of the RV1 vaccine resulted in 6% reduction in the ED visits and 40% reduction in hospital admissions for acute diarrhea.

  7. Contrary To Popular Belief, Medicaid Hospital Admissions Are Often Profitable Because Of Additional Medicare Payments.

    It is generally believed that most hospitals lose money on Medicaid admissions. The data suggest otherwise. Medicaid admissions are often profitable for hospitals because of payments from both the Medicaid program and the Medicare program, including payments for uncompensated care and from the Medicare disproportionate-share hospital program. On average, adding a single Medicaid patient day in fiscal year 2017 will increase most hospitals' Medicare payments by more than $300. When added to Medicaid payments, these payments often cause Medicaid patients to be profitable for hospitals. In contrast, adding a single charity care day in the same year will decrease overall Medicare payments by about $20 on average. The Centers for Medicare and Medicaid Services recently announced a proposal to shift some Medicare payments from supporting hospitals' costs for Medicaid patients to directly supporting their costs for uncompensated care. If that proposal is adopted, hospitals' profits on Medicaid patients would decrease, but their losses on care for the uninsured would be reduced.

    To characterize the increasing incidence and geographic variation of acute diverticulitis. Using the nationwide inpatient sample (NIS) we identified a cohort who had been admitted with diverticulitis between 1998 and 2005. We calculated age-, sex-, and region-specific rates of hospitalizations for diverticulitis over time. The age-adjusted hospitalization rate for diverticulitis increased from 61.8 per 100,000 to 75.5 per 100,000 between 1998 and 2005, and increased similarly in both sexes. Diverticulitis-associated admissions were male-predominant in those younger than age 45 years but were female-predominant thereafter. Admission rates increased the most among those < 45 years, while remaining unchanged for those ≥ 65 years. By 2005, the majority of hospitalized patients were < 65 years. Age-adjusted rates of diverticulitis-associated hospitalizations were lower in the West (50.4/100,000) compared to the Northeast (77.7/100,000), South (73.9/100,000), and Midwest (71.0/100,000). Diverticulitis-associated hospitalizations have steeply risen, especially in young adults. These epidemiological trends vary by geographic region and warrant further investigation into potential dietary and environmental etiologies.

    Objectives. We investigated whether periodic increases in minimum alcohol prices were associated with reduced alcohol-attributable hospital admissions in British Columbia. Methods. The longitudinal panel study (2002–2009) incorporated minimum alcohol prices, density of alcohol outlets, and age- and gender-standardized rates of acute, chronic, and 100% alcohol-attributable admissions. We applied mixed-method regression models to data from 89 geographic areas of British Columbia across 32 time periods, adjusting for spatial and temporal autocorrelation, moving average effects, season, and a range of economic and social variables. Results. A 10% increase in the average minimum price of all alcoholic beverages was associated with an 8.95% decrease in acute alcohol-attributable admissions and a 9.22% reduction in chronic alcohol-attributable admissions 2 years later. A Can$ 0.10 increase in average minimum price would prevent 166 acute admissions in the 1st year and 275 chronic admissions 2 years later. We also estimated significant, though smaller, adverse impacts of increased private liquor store density on hospital admission rates for all types of alcohol-attributable admissions. Conclusions. Significant health benefits were observed when minimum alcohol prices in British Columbia were increased. By contrast, adverse health outcomes were associated with an expansion of private liquor stores. PMID:23597383

    During the 1980s the Republic of Ireland experienced repeated severe pollution episodes. Domestic coal burning was a major source of this pollution. In 1990 the Irish government introduced a ban on the marketing, sale, and distribution of coal in Dublin. The ban was extended to Cork in 1995 and to 10 other communities in 1998 and 2000. We previously reported decreases in particulate black smoke (BS*) and sulfur dioxide (SO2) concentrations, measured as total gaseous acidity, in Dublin after the 1990 coal ban (Clancy et al. 2002). In the current study we explored and compared the effectiveness of the sequential 1990, 1995, and 1998 bans in reducing community air pollution and in improving public health. We compiled records of daily BS, total gaseous acidity (SO2), and counts of cause-specific deaths from 1981 to 2004 for Dublin County Borough (1990 ban), county Cork (1995 ban), and counties Limerick, Louth, Wexford, and Wicklow (1998 ban). We also compiled daily counts of hospital admissions for cardiovascular, respiratory, and digestive diagnoses for Cork County Borough (1991 to 2004) and counties Limerick, Louth, Wexford, and Wicklow (1993 to 2004). We compared pre-ban and post-ban BS and SO2 concentrations for each city. Using interrupted time-series methods, we estimated the change in cause-specific, directly standardized mortality rates in each city or county after the corresponding local coal ban. We regressed weekly age- and sex-standardized mortality rates against an indicator of the post- versus pre-ban period, adjusting for influenza epidemics, weekly mean temperature, and a season smooth of the standardized mortality rates in Coastal counties presumably not affected by the bans. We compared these results with similar analyses in Midlands counties also presumably unaffected by the bans. We also estimated the change in cause-specific, directly standardized, weekly hospital admissions rates normalized for underreporting in each city or county after the 1995

    In low-income countries, live measles vaccine reduces mortality from causes other than measles infection. Such nonspecific effects of vaccines might also be important for the health of children in high-income settings. To examine whether the live vaccine against measles, mumps, and rubella (MMR) is associated with lower rates of hospital admissions for infections among children in Denmark. Population-based cohort study of Danish children born 1997-2006 and followed up from ages 11 months to 2 years (last follow-up, August 31, 2008). Nationwide Danish registers provided data on vaccinations and hospital admissions. The recommended vaccination schedule was inactivated vaccine against diphtheria, tetanus, pertussis, polio, and Haemophilus influenzae type b (DTaP-IPV-Hib) administered at ages 3, 5, and 12 months and MMR at age 15 months. Incidence rate ratios (IRRs) of hospital admissions for any infection, comparing receipt of MMR vs DTaP-IPV-Hib as the most recent vaccine. Risks, risk difference, and number needed to vaccinate were calculated for receiving MMR on time. The study included 495,987 children contributing with 56,889 hospital admissions for any type of infection during 509,427 person-years (rate, 11.2 per 100 person-years). For the 456,043 children who followed the recommended schedule and received MMR after the third dose of DTaP-IPV-Hib, MMR (rate, 8.9 per 100 person-years) vs the third dose of DTaP-IPV-Hib (rate, 12.4 per 100 person-years) as the most recent vaccine was associated with an adjusted IRR of 0.86 (95% CI, 0.84-0.88) for any admission for infection. There were 19,219 children immunized out of sequence. The adjusted IRR was 0.87 (95% CI, 0.80-0.95) for those receiving MMR (rate, 9.9 per 100 person-years) after the second dose of DTaP-IPV-Hib (rate, 15.1 per 100 person-years). However, in the 1981 children who subsequently received the third dose of DTaP-IPV-Hib (rate, 12.8 per 100 person-years) after MMR, the IRR for hospital admissions for

    South Korea faces difficulties in the management of mental disorders, and those difficulties are expected to gradually worsen. Therefore, we analyzed the relationship between social welfare centers and hospital admission after outpatient treatment for mood disorders. We used data from the National Health Insurance Service National Sample Cohort 2002-2013, which included all medical claims filed for the 50,160 patients who were newly diagnosed with a mood disorder among the 1,025,340 individuals in a nationally representative sample. We performed a logistic regression analysis using generalized estimating equation (GEE) models to examine the relationship between social welfare centers and hospital admission after outpatient treatment for mood disorders (ICD-10: F3). There was a 3.9% admission rate among a total of 99,533 person-years. Outpatients who lived in regions with more social welfare centers were less likely to be admitted to a hospital (per increase of five social welfare centers per 100,000 people; OR: 0.958; 95% CI: 0.919-0.999). Social welfare centers had an especially strong protective effect on patients with relatively mild mood disorders and those who were vulnerable to medical expenditures. Considering the protective role of social welfare centers in managing patients with mood disorders, health-policy makers need to consider strategies for activating mental healthcare.

    We sought to determine patient characteristics associated with hospital admission after emergency treatment for asthma, and whether disposition guidelines are followed. We performed a prospective multicenter cohort study involving 64 emergency departments in the United States and Canada. Consecutive adult patients with asthma exacerbations were interviewed, and their charts were reviewed using standardized protocols. Telephone follow-up at 2 weeks determined relapse. Of 1805 patients, 363 (20%; 95% confidence interval [CI]: 18% to 22%) were hospitalized. Among patients with severe exacerbations (final peak flow <50% of predicted), 122 (49%; 95% CI: 43% to 55%) were hospitalized. Admission was associated with final peak flow, female sex, nonwhite race, severity of chronic illness, and severity of exacerbation. Admission predictors were similar regardless of hospital funding, region, or size. Among patients with mild or moderate exacerbations of asthma (peak flow >or=50% predicted), the likelihood of admission was associated significantly with the number of predefined risk factors for death from asthma. Of patients who were discharged from the emergency department, 62 (5%; 95% CI: 4% to 6%) relapsed within 72 hours. Relapse was not associated with final peak flow (P = 0.39). Associations between patient characteristics and disposition were similar across sites. Despite guidelines to the contrary, half of patients with final peak flow <50% were discharged. After emergency department treatment and discharge, short-term relapse was uncommon among patients with asthma, suggesting that strict peak flow cutoffs may be unnecessary if risk factors in patients with mild or moderate exacerbations are considered.

    To explore the association between weather conditions and hospital admissions for pneumonia in Shanghai. A time-series analysis was performed for a period of 4 years (January 2008-December 2011). A generalised additive model was used to calculate the relative risks. Shanghai, China. All daily hospital admissions for pneumonia were obtained from the Shanghai health insurance system between 1 January 2008 and 31 December 2011 (n=99 403). The relationship between the mean temperature and pneumonia hospital admissions followed a V-shaped curve, with an optimum temperature (OT) at 13°C. When the mean temperature was below the OT, a 1°C decrease corresponded to a 4.88% (95% CI 2.71% to 7.09%) and 5.34% (95% CI 2.04% to 8.74%) increase in pneumonia hospital admissions in lag 4 using a single-day lag structure and lag 0-7 using a multiday lag structure. When the mean temperature ≥OT, no adverse effects from the temperature on pneumonia hospital admissions were found. The magnitude of the effects of temperature varied across gender and age groups. Hospitalisations for pneumonia increased by 15.99% (95% CI 0.06% to 34.46%) in the cold period. Cold temperature may be one of the important risk factors for pneumonia hospitalisations. Prevention programmes are needed to reduce the impact of cold temperature on pneumonia hospitalisations such as developing a weather warning system within a wide public health context.

    To chart emergency department (ED) attendance and acute admission following a devastating earthquake in 2011 which lead to Canterbury's rapidly accelerated integrated health system transformations. Interrupted time series analysis, modelling using Bayesian change-point methods, of ED attendance and acute admission rates over the 2008-2014 period. ED department within the Canterbury District Health Board; with comparison to two other district health boards unaffected by the earthquake within New Zealand. Canterbury's health system services ∼500 000 people, with around 85 000 ED attendances and 37 000 acute admissions per annum. De-seasoned standardised population ED attendance and acute admission rates overall, and stratified by age and sex, compared before and after the earthquake. Analyses revealed five global patterns: (1) postearthquake, there was a sudden and persisting decrease in the proportion of the population attending the ED; (2) the growth rate of ED attendances per head of population did not change between the pre-earthquake and postearthquake periods; (3) postearthquake, there was a sudden and persisting decrease in the proportion of the population admitted to hospital; (4) the growth rate of hospital admissions per head of the population declined between pre-earthquake and postearthquake periods and (5) the most dramatic reduction in hospital admissions growth after the earthquake occurred among those aged 65+ years. Extrapolating from the projected and fitted deseasoned rates for December 2014, ∼676 (16.8%) of 4035 projected hospital admissions were avoided. While both necessarily and opportunistically accelerated, Canterbury's integrated health systems transformations have resulted in a dramatic and sustained reduction in ED attendances and acute hospital admissions. This natural intervention experiment, triggered by an earthquake, demonstrated that integrated health systems with high quality out-of-hospital care models are likely to

    A wider spectrum 13-valent pneumococcal vaccine (PCV13) replaced PCV7 in the child immunization schedule in England from 2010. We assessed the additional impact of PCV13 over PCV7 on all-cause pneumonia and empyema admissions. We extracted Hospital Episode Statistics data from 2001 to 2014 on all-cause pneumonia (ICD-10 codes J12-18) and empyema admissions (J86.0, J86.9) for children <16 years in England. Trend analysis and rate ratios (RR) were calculated comparing the Pre-vaccine era to September 2006, the PCV7 era and the PCV13 era from April 2010. Annual hospital admissions for pneumonia and empyema were increasing in the Pre-vaccine era peaking in 2005 at 15,733 pneumonia and 382 empyema cases (158.6 and 3.9 per 100,000 children, respectively). These rates fell following PCV7 introduction in 2006 but began to climb soon afterwards until PCV13 was introduced. By 2013, admission rates for pneumonia and empyema were 102.2 and 1.9 per 100,000 children, respectively. We found no added benefit of PCV13 over PCV7 on pneumonia admissions following PCV13 introduction but there was a significant decrease in empyema admissions in children aged <2 years (RR 0.58; 95% CI 0.34-0.99). Additional serotypes covered by PCV13 may be more important in the aetiology of empyema and invasive disease than as a cause of uncomplicated pneumonia.

    Background. Wildfires are anticipated to be more frequent and intense under climate change. As a result, wildfires may emit more air pollutants that can harm health in communities in the future. The health impacts of wildfire smoke under climate change are largely unknown. Methods. We linked projections of future levels of fine particulate matter (PM2.5) specifically from wildfire smoke under the A1B climate change scenario using the GEOS-Chem model for 2046-2051, present-day estimates of hospital admission impacts from wildfire smoke, and future population projections to estimate the change in respiratory hospital admissions for persons ≥65 years by county (n = 561) from wildfire PM2.5 under climate change in the Western US. Results. The increase in intense wildfire smoke days from climate change would result in an estimated 178 (95% confidence interval: 6.2, 361) additional respiratory hospital admissions in the Western US, accounting for estimated future increase in the elderly population. Climate change is estimated to impose an additional 4990 high-pollution smoke days. Central Colorado, Washington and southern California are estimated to experience the highest percentage increase in respiratory admissions from wildfire smoke under climate change. Conclusion. Although the increase in number of respiratory admissions from wildfire smoke seems modest, these results provide important scientific evidence of an often-ignored aspect of wildfire impact, and information on their anticipated spatial distribution. Wildfires can cause serious social burdens such as property damage and suppression cost, but can also raise health problems. The results provide information that can be incorporated into development of environmental and health policies in response to climate change. Climate change adaptation policies could incorporate scientific evidence on health risks from natural disasters such as wildfires.

    There are few data describing patient-identified precipitants of heart failure (HF) hospitalization. We hypothesized a patient's perception of reason for or preventability of an admission may be related to 30-day readmission rates. Ninety-four patients admitted with decompensated HF from July 2014 to March 2015 completed a brief questionnaire regarding circumstances leading to admission. Thirty-day outcomes were assessed via telephone call and chart review. Mean age was 58 ± 14 years, with 60% blacks (n = 56) and 41% females (n = 39). Median left ventricular ejection fraction was 30%; 27 had preserved ejection fraction. Seventy-two patients identified their hospitalization to be due to HF (± another condition). Most common patient-identified precipitants of admission were worsening HF (n = 37) and dietary nonadherence (n = 11). Readmitted patients tended to have longer time until first follow-up appointment (21 vs 8 days). Seven of the 42 patients who identified their hospitalization as preventable were readmitted compared with 21/49 who believed their hospitalization was unpreventable (P = .012). On multivariate regression analysis, patients who thought their hospitalization was preventable were less likely to be readmitted (odds ratio 0.31; 95% confidence interval 0.10-0.91; P = .04). Almost 50% of patients believe their HF hospitalization is preventable, and these patients appear to be less likely to be readmitted within 30 days. Notably, patients cite nonadherence and lack of knowledge as reasons hospitalizations are preventable. These results lend insight into possible interventions to reduce HF readmissions.

    To report on long-term trends in hospital admission rates for anorexia nervosa using two English datasets. We used data on hospital day-case and inpatient care across five decades in the Oxford Record Linkage Study (ORLS), and similar data for all England from 1990. We analysed rates of admission for anorexia nervosa in people aged 10-44 years, using hospital episodes (counting every admission) and first-recorded admissions (counting only the first record for each person). Former Oxford NHS Region; and England. None; anonymous statistical records were used. In the longstanding ORLS, the age-standardised first-recorded admission rate for women was 2.7 (95% confidence interval 1.6-3.8) per 100,000 female population aged 10-44 years in 1968-1971; 2.7 (2.1-3.3) in 1992-1996; and 6.3 (5.5-7.2) in 2007-2011. Male rates were zero in the 1960s; 0.07 (0.0-0.1) per 100,000 men in 1992-1996; and 0.4 (0.2-0.6) in 2007-2011. In England, female rates increased from 4.2 (4.0-4.4) in 1998-2001 to 6.9 (6.7-7.1) in 2007-2011; and the corresponding male rates were 0.2 (0.1-0.3) and 0.5 (0.4-0.6). Episode-based admission rates rose more than person-based rates. The highest rates by far were in girls and women aged 15-19 years. In recent years, anorexia nervosa has become a greater burden on secondary care: not only have admission rates increased but so too have multiple admissions per person with anorexia nervosa. The increase in admission rates might reflect an increase in prevalence rates of anorexia nervosa in the general population, but other explanations, including lower clinical thresholds for admission, are possible and are discussed. © The Royal Society of Medicine.

    This study assessed the association between respiratory hospital admissions and PM10 pollution in Utah, Salt Lake, and Cache valleys during April 1985 through March 1989. Utah and Salt Lake valleys had high levels of PM10 pollution that violated both the annual and 24-h standards issued by the Environmental Protection Agency (EPA). Much lower PM10 levels occurred in the Cache Valley. Utah Valley experienced the intermittent operation of its primary source of PM10 pollution: an integrated steel mill. Bronchitis and asthma admissions for preschool-age children were approximately twice as frequent in Utah Valley when the steel mill was operating versus whenmore » it was not. Similar differences were not observed in Salt Lake or Cache valleys. Even though Cache Valley had higher smoking rates and lower temperatures in winter than did Utah Valley, per capita bronchitis and asthma admissions for all ages were approximately twice as high in Utah Valley. During the period when the steel mill was closed, differences in per capita admissions between Utah and Cache valleys narrowed considerably. Regression analysis also demonstrated a statistical association between respiratory hospital admissions and PM10 pollution. The results suggest that PM10 pollution plays a role in the incidence and severity of respiratory disease.« less

    It has been postulated that patients admitted on weekends or after office hours may experience delays in clinical management and consequently have longer length of stay (LOS). We investigated if day and time of admission is associated with LOS in Tan Tock Seng Hospital (TTSH), a 1,400 bed acute care tertiary hospital serving the central and northern regions of Singapore. This was a historical cohort study based on all admissions from TTSH from 1st September 2003 to 31st August 2004. Data was extracted from routinely available computerized hospital information systems for analysis by episode of care. LOS for each episode of care was log-transformed before analysis, and a multivariate linear regression model was used to study if sex, age group, type of admission, admission source, day of week admitted, admission on a public holiday or eve of public holiday, admission on a weekend and admission time were associated with an increased LOS. In the multivariate analysis, sex, age group, type of admission, source of admission, admission on the eve of public holiday and weekends and time of day admitted were independently and significantly associated with LOS. Patients admitted on Friday, Saturday or Sunday stayed on average 0.3 days longer than those admitted on weekdays, after adjusting for potential confounders; those admitted on the eve of public holidays, and those admitted in the afternoons and after office hours also had a longer LOS (differences of 0.71, 1.14 and 0.65 days respectively). Cases admitted over a weekend, eve of holiday, in the afternoons, and after office hours, do have an increased LOS. Further research is needed to identify processes contributing to the above phenomenon.

    Understanding how European care of chronic obstructive pulmonary disease (COPD) admissions vary against guideline standards provides an opportunity to target appropriate quality improvement interventions. In 2010-2011 an audit of care against the 2010 'Global initiative for chronic Obstructive Lung Disease' (GOLD) standards was performed in 16 018 patients from 384 hospitals in 13 countries. Clinicians prospectively identified consecutive COPD admissions over a period of 8 weeks, recording clinical care measures on a web-based data tool. Data were analysed comparing adherence to 10 key management recommendations. Adherence varied between hospitals and across countries. The lack of available spirometry results and variable use of oxygen and non-invasive ventilation (NIV) are high impact areas identified for improvement.

A review of the medical notes of all patients admitted with a primary diagnosis of constipation to the children's ward of a district general hospital over a 12-month period. Of 41 admissions (19 girls and 22 boys, age range 6 weeks to 12 years), the average length of stay was less than two nights. The short duration of hospital stay implies rapid improvement. It is likely that many of these children could have been managed in the community if suitable resources, such as a community nurse specialising in constipation, were available.

    A 39-year-old man died of multi-organ failure complicating mixed drug toxicity that included methadone, oxazepam, oxycodone and nitrazepam. His past medical history involved alcohol and poly-substance abuse with chronic self-harm and suicidal ideation. There had been multiple hospital admissions for drug overdoses. At autopsy the most unusual finding was of two packages of 10 tablets each, wrapped in thin plastic film within the rectum. The insertion of drugs into body orifices and cavities has been termed body pushing to distinguish it from body packing where illicit drugs are wrapped and swallowed for transport and smuggling, and body stuffing where small amounts of loosely wrapped or unwrapped drugs are swallowed to conceal evidence from police. This case demonstrates that body pushing may not always involve illicit drugs or attempted concealment from police or customs officials. It appears that the drugs had been hidden to ensure an additional supply during the time of residence in hospital. The extent to which body pushing is currently being used by patients to smuggle drugs into secure medical facilities is yet to be determined.

    Anemia at hospitalization is often treated as an accompaniment to an underlying illness, without active investigation, despite its association with morbidity. Development of hospital-acquired anemia (HAA) has also been associated with increased risk for poor outcomes. Together, they may further heighten morbidity risk from bad to worse. The aims of this study were to (1) examine mortality, length of stay, and total charges in patients with present-on-admission (POA) anemia and (2) determine whether these are exacerbated by development of HAA. In this cohort investigation, from January 1, 2009, to August 31, 2011, a total of 44,483 patients with POA anemia were admitted to a single health system compared with a reference group of 48,640 without POA anemia or HAA. Data sources included the University HealthSystem Consortium database and electronic medical records. Risk-adjustment methods included logistic and linear regression models for mortality, length of stay, and total charges. Present-on-admission anemia was defined by administrative coding. Hospital-acquired anemia was determined by changes in hemoglobin values from the electronic medical record. Approximately one-half of the patients experienced worsening of anemia with development of HAA. Risk for death and resource use increased with increasing severity of HAA. Those who developed severe HAA had 2-fold greater odds for death; that is, mild POA anemia with development of severe HAA resulted in greater mortality (odds ratio, 2.57; 95% confidence interval, 2.08-3.18; P < 0.001), increased length of stay (2.23; 2.16-2.31; P < 0.001), and higher charges (2.09; 2.03-2.15; P < 0.001). Present-on-admission anemia is associated with increased mortality and resource use. This risk is further increased from bad to worse when patients develop HAA. Efforts to address POA anemia and HAA deserve attention.

    On January 11, 2009, a comprehensive smoking ban was implemented in Taiwan. The aim of this study was to evaluate the effect of this ban on hospital admissions for ischemic heart disease (IHD). Trends in the country-level monthly hospital admission rates for IHD were determined and frequency compared to other conditions such as control conditions cholecystitis, bowel obstruction, and appendicitis from January 1997 (1 year before the first phase of smoke-free laws was implemented) to December 2012 (3 years after the second phase of the ban). Poisson regression with a monthly time-series model was used to determine alterations in the trend of admission rates for IHD with comparison to rates of other disorders after the ban. Hospital admissions for IHD decreased by 0.8% (incidence rate ratio [RR]: 0.992; 95% confidence interval [CI] = 0.991-0.994) and 1.1% (incidence RR: 0.989; 95% CI = 0.988-0.991) following the first (September 19, 1997 to January 10, 2009) and second (January 11, 2009 to December 31, 2012) phases of the ban, respectively, compared with those prior to the pre-ban period, the corresponding values for the control conditions were 0.6% (95% CI = 0.5%-0.7%) and 0.7% (95% CI = 0.6%-0.9%). The admission rates significantly fell for both men and women and for all examined age categories after both first and second phases of the ban. The present findings provide evidence of a significant reduction in hospital admissions for IHD in Taiwan following smoking bans.

    Studies have raised concern about the safety of generic compared with branded drugs. Febrile neutropenia (FN) resulting in hospital admission was compared between the branded docetaxel (Taxotere®, Sanofi) and 2 generic formulations (docetaxel Ebewe and docetaxel Hospira) in patients with breast cancer. This was a retrospective study that included patients with breast cancer who received docetaxel between January 2012 and December 2014. Patients who had an admission diagnosis of FN and had received docetaxel within 14 days prior to admission were evaluated. The docetaxel brand and dose, patient characteristics, hospital length of stay, admission to the intensive care unit (ICU), and mortality were recorded. During the study period, 2904 cycles of docetaxel were given for 876 patients (1519 cycles of docetaxel Sanofi, 811 cycles of docetaxel Hospira, and 574 cycles of docetaxel Ebewe). Among the cycles given, 130 cycles were associated with FN that required hospital admission. The overall incidence of FN resulting in hospital admission was significantly higher in patients who had received docetaxel Hospira, compared with patients who had received docetaxel Sanofi (47[5.8%] cycles vs 53 [3.5%] cycles, P = .009), but there was no significant difference between docetaxel Ebewe and docetaxel Sanofi (30[5.2%] cycles vs 53 [3.5%] cycles, P = .069). All cases of FN resolved except for 1 patient who died in the ICU after receiving docetaxel Ebewe. There was a significant difference in the incidence of FN between docetaxel Sanofi and docetaxel Hospira, but all cases in both groups resolved completely. © 2016, The American College of Clinical Pharmacology.

    ABSTRACT OBJECTIVE To investigate whether the psychiatric hospitalization rates due to use of psychoactive substances and average time of hospitalization suffered any changes after the first decade of effective implementation of the psychiatric reform in Brazil. METHODS This article examines the evolution of hospitalizations due to disorders arising from the use of alcohol or other substances in the state of Santa Catarina, Southern Brazil, from 2000 to 2012. This is an ecological, time-series study, which uses data from admissions obtained by the Informatics Service of the Brazilian Unified Health System. Hospitalization rates by 100,000 inhabitants and average time of occupancy of beds were estimated. Coefficients of variation of these rates were estimated by Poisson Regression. RESULTS The total and male hospitalization rates did not vary (p = 0.056 and p = 0.244, respectively). We observed an increase of 3.0% for the female sex (p = 0.049). We did not observe any significant variation for occupancy time of beds. CONCLUSIONS The deployment of services triggered by the Brazilian psychiatric reform was not accompanied by a reduction of hospitalization rates or mean occupancy time of hospitalized patients during this first decade of implementation of the reform.

    Abdominal aortic aneurysms (AAA) are serious disease with a high fatality rate but recent epidemiologic data showed a decrease of AAA mortality. Our objective was to estimate, in France, the hospitalization, inhospital mortality and mortality rates due to AAA and to analyze their trends over time. Hospitalization data were extracted from the hospital discharge summaries in the national database between 2002 and 2013. The analysis covered all patients hospitalized for AAA as a principal diagnosis. During the same period, all death certificates mentioning AAA as an initial cause of death were included in the study. Crude and standardized rates were calculated according to age and sex. Poisson regression was used to analyze the average annual percent change. In 2013, there were 8853 patients hospitalized for AAA in France (7986 unruptured and 867 ruptured). Between 2002 and 2013, the rate of patients hospitalized for unruptured AAA decreased slightly in men (-5.0%) but increased in women (+5.2%). By contrast, the rate of patients hospitalized for ruptured AAA has decreased by >20% in men and women. The proportion of endovascular treatment of unruptured AAA rose from <10% in 2005 to 35% in women and 40% in men in 2013. In 2013, 939 deaths from AAA were recorded. Mortality for this disease declined significantly from 2002 to 2013 in men and women. The unfavorable epidemiological trends in women and important evolution of the management of AAA call for an epidemiological surveillance of this disease. Copyright © 2017 Elsevier B.V.

    Low back pain (LBP), from degenerative lumbar spine disease, represents a significant burden on healthcare resources. Studies worldwide report trends attributable to their country's specific demographics and healthcare system. Considering England's specific medico-socioeconomic conditions, we investigate recent trends in hospital admissions and procedures for LBP, and discuss the implications for the allocation of healthcare resources. Retrospective cohort study using Hospital Episode Statistics data relating to degenerative lumbar spine disease in England, between 1999 and 2013. Regression models were used to analyse trends. Trends in the number of admissions and procedures for LBP, mean patient age, gender and length of stay. Hospital admissions and procedures have increased significantly over the study period, from 127.09 to 216.16 and from 24.5 to 48.83 per 100,000, respectively, (p<0.001). The increase was most marked in the oldest age groups with a 1.9 and 2.33-fold increase in admissions for patients aged 60-74 and ≥ 75 years, respectively, and a 2.8-fold increase in procedures for those aged ≥ 60 years. Trends in hospital admissions were characterised by a widening gender gap, increasing mean patient age, and decreasing mean hospital stay (p<0.001). Trends in procedures were characterised by a narrowing gender gap, increasing mean patient age (p=0.014) and decreasing mean hospital stay (p<0.001). Linear regression models estimate that each hospital admission translates to 0.27 procedures, per 100,000 (95% CI 0.25 to 0.30, r 0.99, p<0.001; r, Pearson's correlation coefficient). Hospital admissions are increasing at 3.5 times the rate of surgical procedures (regression gradient 7.63 vs 2.18 per 100,000/year). LBP represents a significant and increasing workload for hospitals in England. These trends demonstrate an increasing demand for specialists involved in the surgical and non-surgical management of this disease, and highlight the need for services

    Introduction Patient-controlled hospital admission for individuals with severe mental disorders is a novel approach in mental healthcare. Patients can admit themselves to a hospital unit for a short stay without being assessed by a psychiatrist or contacting the emergency department. Previous studies assessing the outcomes of patient-controlled hospital admission found trends towards reduction in the use of coercive measures and length of hospital stay; however, these studies have methodological shortcomings and small sample sizes. Larger studies are needed to estimate the effect of patient-controlled hospital admission on the use of coercion and of healthcare services. Design and methods We aim to recruit at least 315 patients who are offered a contract for patient-controlled hospital admissions in eight different hospitals in Denmark. Patients will be followed-up for at least 1 year to compare the use of coercive measures and of healthcare services, the use of medications and suicidal behaviour. Descriptive statistics will be used to investigate hospitalisations, global assessment of functioning (GAF) and patient satisfaction with treatment. To minimise selection bias, we will match individuals using patient-controlled hospital admission and controls with a 1:5 ratio via a propensity score based on the following factors: sex, age group, primary diagnosis, substance abuse as secondary diagnosis, coercion, number of psychiatric bed days, psychiatric history, urbanity and suicidal behaviour. Additionally, a historical control study will be undertaken in which patients serve as their own control group prior to index date. Ethics and dissemination The study has been approved by The Danish Health and Medicines Authority (j.nr.: 3-3013-934/1/) and by The Danish Data Protection Agency (j.nr.: 2012-58-0004). The study was categorised as a register study by The Danish Health Research Ethics Committee and therefore no further approval was needed (j.nr.: H-2-2014-FSP70

    Objective To investigate the association between helmet legislation and admissions to hospital for cycling related head injuries among young people and adults in Canada. Design Interrupted time series analysis using data from the National Trauma Registry Minimum Data Set. Setting Canadian provinces and territories; between 1994 and 2003, six of 10 provinces implemented helmet legislation. Participants All admissions (n=66 716) to acute care hospitals in Canada owing to cycling related injury between 1994 and 2008. Main outcome measure Rate of admissions to hospital for cycling related head injuries before and after the implementation of provincial helmet legislation. Results Between 1994 and 2008, 66 716 hospital admissions were for cycling related injuries in Canada. Between 1994 and 2003, the rate of head injuries among young people decreased by 54.0% (95% confidence interval 48.2% to 59.8%) in provinces with helmet legislation compared with 33.1% (23.3% to 42.9%) in provinces and territories without legislation. Among adults, the rate of head injuries decreased by 26.0% (16.0% to 36.3%) in provinces with legislation but remained constant in provinces and territories without legislation. After taking baseline trends into consideration, however, we were unable to detect an independent effect of legislation on the rate of hospital admissions for cycling related head injuries. Conclusions Reductions in the rates of admissions to hospital for cycling related head injuries were greater in provinces with helmet legislation, but injury rates were already decreasing before the implementation of legislation and the rate of decline was not appreciably altered on introduction of legislation. While helmets reduce the risk of head injuries and we encourage their use, in the Canadian context of existing safety campaigns, improvements to the cycling infrastructure, and the passive uptake of helmets, the incremental contribution of provincial helmet legislation to reduce

    AIM: To characterize the increasing incidence and geographic variation of acute diverticulitis. METHODS: Using the nationwide inpatient sample (NIS) we identified a cohort who had been admitted with diverticulitis between 1998 and 2005. We calculated age-, sex-, and region-specific rates of hospitalizations for diverticulitis over time. RESULTS: The age-adjusted hospitalization rate for diverticulitis increased from 61.8 per 100 000 to 75.5 per 100 000 between 1998 and 2005, and increased similarly in both sexes. Diverticulitis-associated admissions were male-predominant in those younger than age 45 years but were female-predominant thereafter. Admission rates increased the most among those < 45 years, while remaining unchanged for those ≥ 65 years. By 2005, the majority of hospitalized patients were < 65 years. Age-adjusted rates of diverticulitis-associated hospitalizations were lower in the West (50.4/100 000) compared to the Northeast (77.7/100 000), South (73.9/100 000), and Midwest (71.0/100 000). CONCLUSION: Diverticulitis-associated hospitalizations have steeply risen, especially in young adults. These epidemiological trends vary by geographic region and warrant further investigation into potential dietary and environmental etiologies. PMID:21472127

    To determine the impact of a health system-wide fetal fibronectin (fFN) testing programme on the rates of hospital admission for preterm labour (PTL). Multiple baseline time-series design. Canadian province of Ontario. A retrospective population-based cohort of antepartum and delivered obstetrical admissions in all Ontario hospitals between 1 April 2002 and 31 March 2010. International Classification of Diseases codes in a health system-wide hospital administrative database were used to identify the study population and define the outcome measure. An aggregate time series of monthly rates of hospital admissions for PTL was analysed using segmented regression models after aligning the fFN test implementation date for each institution. Rate of obstetrical hospital admission for PTL. Estimated rates of hospital admission for PTL following fFN implementation were lower than predicted had pre-implementation trends prevailed. The reduction in the rate was modest, but statistically significant, when estimated at 12 months following fFN implementation (-0.96 hospital admissions for PTL per 100 preterm births; 95% confidence interval [CI], -1.02 to -0.90, P = 0.04). The statistically significant reduction was sustained at 24 and 36 months following implementation. Using a robust quasi-experimental study design to overcome confounding as a result of underlying secular trends or concurrent interventions, we found evidence of a small but statistically significant reduction in the health system-level rate of hospital admissions for PTL following implementation of fFN testing in a large Canadian province. © 2013 Royal College of Obstetricians and Gynaecologists.

    The influence of the changes in atmospheric state, typical for areas close to big deserts, on acute myocardial infarction (AMI) was analyzed. Under test was the group of 3256 patients (77 % males, 23 % females), hospitalized in the Cardio-Surgical Department of Soroka Medical Center at Ben-Gurion University (BGU, Israel) during 2000-2008. To explore the relationship between atmospheric parameters and AMI, multivariate regression analysis has been performed. AMI was most frequent in winter to spring and least in summer. The highest number of cases was recorded in December and the lowest in September. Hospital admissions showed a higher prevalence in men than in women; the ratio is 3.3/1.0. About 60 % of males were aged between 45 and 65 years old with maximum ˜55 (21 %), whereas 60 % of women hospital admissions were aged between 65 and 80 years old with maximum ˜72 (24 %). The result suggested that the monthly mean relative humidity at daytime and its overall daily differences, wind speed, and respirable fraction of particulate concentration are associated with the admission for AMI. The results of the study confirm the importance of atmospheric state variability for cardiovascular diseases.

    We evaluated the association between short-term exposure to ambient ozone air pollution and stroke hospital admissions among adult residents of South Carolina (SC). Data on all incident stroke hospitalizations from 2002 to 2006 were obtained from the SC Office of Research and Statistics. Ozone exposure data were obtained from the US Environmental Protection Agency's Hierarchical Bayesian Model. A semi-symmetric bidirectional case-crossover design was used to examine the association between ozone exposure on lag days 0-2 (0 to 2 days before admission) and stroke hospitalization. Conditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). No significant associations were observed between short-term ozone exposure and hospitalization for all stroke (e.g., lag day 0: OR=0.98; 95% CI=0.96, 1.00) or ischemic stroke (lag day 0: OR=0.98; 95% CI=0.96, 1.01). Risk of hospitalization for hemorrhagic stroke appeared to be higher among African Americans than European Americans; however, the majority of these associations did not reach statistical significance. Among adults in SC from 2002 to 2006, there was no evidence of an association between ozone exposure and risk of hospitalization for all stroke or ischemic stroke; however, African Americans may have an increased risk of hemorrhagic stroke.

    The purpose of this study was to investigate the relationship between heart rate at admission and in-hospital mortality in patients with ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation acute coronary syndrome (NSTE-ACS). Consecutive ACS patients admitted in 2008-2010 across 58 hospitals in six participant countries of the European Hospital Benchmarking by Outcomes in ACS Processes (EURHOBOP) project (Finland, France, Germany, Greece, Portugal and Spain). Cardiogenic shock patients were excluded. Associations between heart rate at admission in categories of 10 beats per min (bpm) and in-hospital mortality were estimated by logistic regression in crude models and adjusting for age, sex, obesity, smoking, hypertension, diabetes, known heart failure, renal failure, previous stroke and ischaemic heart disease. In total 10,374 patients were included. In both STEMI and NSTE-ACS patients, a U-shaped relationship between admission heart rate and in-hospital mortality was found. The lowest risk was observed for heart rates between 70-79 bpm in STEMI and 60-69 bpm in NSTE-ACS; risk of mortality progressively increased with lower or higher heart rates. In multivariable models, the relationship persisted but was significant only for heart rates >80 bpm. A similar relationship was present in both patients with or without diabetes, above or below age 75 years, and irrespective of the presence of atrial fibrillation or use of beta-blockers. Heart rate at admission is significantly associated with in-hospital mortality in patients with both STEMI and NSTE-ACS. ACS patients with admission heart rate above 80 bpm are at highest risk of in-hospital mortality.

    This study was undertaken to determine whether there was a correlation between ambient ozone (O 3 ) levels and number of hospital admissions for myocardial infarction (MI) in Taipei, Taiwan. Hospital admissions for MI and ambient air pollution data for Taipei were obtained for the period from 2006 to 2010. The relative risk (RR) of hospital admissions for MI was estimated using a time-stratified case-crossover approach, controlling for weather variables, day of the week, seasonality, and long-term time trends. For the single-pollutant model (without adjustment for other pollutants), increased RR for a number of MI admissions was significantly associated with higher O 3 levels both on warm days (>23°C) and on cool days (<23°C). This observation was accompanied by an interquartile range elevation correlated with a 7% (95% CI = 2%-12%) and 17% (95% CI = 11%-25%) rise in number of MI admissions, respectively. In the two-pollutant models, no significant associations between ambient O 3 concentrations and number of MI admissions were observed on warm days. However, on cool days, correlation between ambient O 3 after inclusion of each of the other five pollutants, particulate matter (PM 10 or PM 2.5 ), sulfur dioxide (SO 2 ), nitrogen dioxide (NO 2 ) or carbon monoxide (CO), and number of MI admissions remained significant. This study provides evidence that higher levels of ambient O 3 increase the RR of number of hospital admissions for MI.

  20. No evidence of purported lunar effect on hospital admission rates or birth rates.

    Studies indicate that a fraction of nursing professionals believe in a "lunar effect"-a purported correlation between the phases of the Earth's moon and human affairs, such as birth rates, blood loss, or fertility. This article addresses some of the methodological errors and cognitive biases that can explain the human tendency of perceiving a lunar effect where there is none. This article reviews basic standards of evidence and, using an example from the published literature, illustrates how disregarding these standards can lead to erroneous conclusions. Román, Soriano, Fuentes, Gálvez, and Fernández (2004) suggested that the number of hospital admissions related to gastrointestinal bleeding was somehow influenced by the phases of the Earth's moon. Specifically, the authors claimed that the rate of hospital admissions to their bleeding unit is higher during the full moon than at other times. Their report contains a number of methodological and statistical flaws that invalidate their conclusions. Reanalysis of their data with proper procedures shows no evidence that the full moon influences the rate of hospital admissions, a result that is consistent with numerous peer-reviewed studies and meta-analyses. A review of the literature shows that birth rates are also uncorrelated to lunar phases. Data collection and analysis shortcomings, as well as powerful cognitive biases, can lead to erroneous conclusions about the purported lunar effect on human affairs. Adherence to basic standards of evidence can help assess the validity of questionable beliefs.

    Objective. To examine whether comprehensive smoke-free air laws enacted in Florida, New York, and Oregon are associated with reductions in hospital admissions for acute myocardial infarction (AMI) and stroke. Methods. Analyzed trends in county-level, age-adjusted, hospital admission rates for AMI and stroke from 1990 to 2006 (quarterly) for Florida, 1995 to 2006 (monthly) for New York, and 1998 to 2006 (monthly) for Oregon to identify any association between admission rates and passage of comprehensive smoke-free air laws. Interrupted time series analysis was used to adjust for the effects of preexisting moderate local-level laws, seasonal variation in hospital admissions, differences across counties, and a secular time trend. Results. More than 3 years after passage of statewide comprehensive smoke-free air laws, rates of hospitalization for AMI were reduced by 18.4% (95% CI: 8.8–28.0%) in Florida and 15.5% (95% CI: 11.0–20.1%) in New York. Rates of hospitalization for stroke were reduced by 18.1% (95% CI: 9.3–30.0%) in Florida. The few local comprehensive laws in Oregon were not associated with reductions in AMI or stroke statewide. Conclusion. Comprehensive smoke-free air laws are an effective policy tool for reducing the burden of AMI and stroke. PMID:22778759

    To examine the impact of Massachusetts healthcare reform on changes in rates of admission to hospital for ambulatory care sensitive conditions (ACSCs), which are potentially preventable with good access to outpatient medical care, and racial and ethnic disparities in such rates, using complete inpatient discharge data (hospital episode statistics) from Massachusetts and three control states. Difference in differences analysis to identify the change, overall and according to race/ethnicity, adjusted for secular changes unrelated to reform. Hospitals in Massachusetts, New York, New Jersey, and Pennsylvania, United States. Adults aged 18-64 (those most likely to have been affected by the reform) admitted for any of 12 ACSCs in the 21 months before and after the period during which reform was implemented (July 2006 to December 2007). Admission rates for a composite of all 12 ACSCs, and subgroup composites of acute and chronic ACSCs. After adjustment for potential confounders, including age, race and ethnicity, sex, and county income, unemployment rate and physician supply, we found no evidence of a change in the admission rate for overall composite ACSC (1.2%, 95% confidence interval -1.6% to 4.1%) or for subgroup composites of acute and chronic ACSCs. Nor did we find a change in disparities in admission rates between black and white people (-1.9%, -8.5% to 5.1%) or white and Hispanic people (2.0%, -7.5% to 12.4%) for overall composite ACSC that existed in Massachusetts before reform. In analyses limited to Massachusetts only, we found no evidence of a change in admission rate for overall composite ACSC between counties with higher and lower rates of uninsurance at baseline (1.4%, -2.3% to 5.3%). Massachusetts reform was not associated with significantly lower overall or racial and ethnic disparities in rates of admission to hospital for ACSCs. In the US, and Massachusetts in particular, additional efforts might be needed to improve access to outpatient care and reduce

    Increased mortality rates associated with weekend hospital admission (the so-called weekend effect) have been attributed to suboptimum staffing levels of specialist consultants. However, evidence for a causal association is elusive, and the magnitude of the weekend specialist deficit remains unquantified. This uncertainty could hamper efforts by national health systems to introduce 7 day health services. We aimed to examine preliminary associations between specialist intensity and weekend admission mortality across the English National Health Service. Eligible hospital trusts were those in England receiving unselected emergency admissions. On Sunday June 15 and Wednesday June 18, 2014, we undertook a point prevalence survey of hospital specialists (consultants) to obtain data relating to the care of patients admitted as emergencies. We defined specialist intensity at each trust as the self-reported estimated number of specialist hours per ten emergency admissions between 0800 h and 2000 h on Sunday and Wednesday. With use of data for all adult emergency admissions for financial year 2013-14, we compared weekend to weekday admission risk of mortality with the Sunday to Wednesday specialist intensity ratio within each trust. We stratified trusts by size quintile. 127 of 141 eligible acute hospital trusts agreed to participate; 115 (91%) trusts contributed data to the point prevalence survey. Of 34,350 clinicians surveyed, 15,537 (45%) responded. Substantially fewer specialists were present providing care to emergency admissions on Sunday (1667 [11%]) than on Wednesday (6105 [42%]). Specialists present on Sunday spent 40% more time caring for emergency patients than did those present on Wednesday (mean 5·74 h [SD 3·39] vs 3·97 h [3·31]); however, the median specialist intensity on Sunday was only 48% (IQR 40-58) of that on Wednesday. The Sunday to Wednesday intensity ratio was less than 0·7 in 104 (90%) of the contributing trusts. Mortality risk among patients

    There is limited information on the public health impact of wildfires. The relationship of cardiorespiratory hospital admissions (n = 40 856) to wildfire-related particulate matter (PM(2.5)) during catastrophic wildfires in southern California in October 2003 was evaluated. Zip code level PM(2.5) concentrations were estimated using spatial interpolations from measured PM(2.5), light extinction, meteorological conditions, and smoke information from MODIS satellite images at 250 m resolution. Generalised estimating equations for Poisson data were used to assess the relationship between daily admissions and PM(2.5), adjusted for weather, fungal spores (associated with asthma), weekend, zip code-level population and sociodemographics. Associations of 2-day average PM(2.5) with respiratory admissions were stronger during than before or after the fires. Average increases of 70 microg/m(3) PM(2.5) during heavy smoke conditions compared with PM(2.5) in the pre-wildfire period were associated with 34% increases in asthma admissions. The strongest wildfire-related PM(2.5) associations were for people ages 65-99 years (10.1% increase per 10 microg/m(3) PM(2.5), 95% CI 3.0% to 17.8%) and ages 0-4 years (8.3%, 95% CI 2.2% to 14.9%) followed by ages 20-64 years (4.1%, 95% CI -0.5% to 9.0%). There were no PM(2.5)-asthma associations in children ages 5-18 years, although their admission rates significantly increased after the fires. Per 10 microg/m(3) wildfire-related PM(2.5), acute bronchitis admissions across all ages increased by 9.6% (95% CI 1.8% to 17.9%), chronic obstructive pulmonary disease admissions for ages 20-64 years by 6.9% (95% CI 0.9% to 13.1%), and pneumonia admissions for ages 5-18 years by 6.4% (95% CI -1.0% to 14.2%). Acute bronchitis and pneumonia admissions also increased after the fires. There was limited evidence of a small impact of wildfire-related PM(2.5) on cardiovascular admissions. Wildfire-related PM(2.5) led to increased respiratory hospital

    Background There has been limited research investigating the relationship between injurious falls and hospital resource use. The aims of this study were to identify clusters of community-dwelling older people in the general population who are at increased risk of being admitted to hospital following a fall and how those clusters differed in their use of hospital resources. Methods Analysis of routinely collected hospital admissions data relating to 45 374 fall-related admissions in Victorian community-dwelling older adults aged ≥65 years that occurred during 2008/2009 to 2010/2011. Fall-related admission episodes were identified based on being admitted from a private residence to hospital with a principal diagnosis of injury (International Classification of Diseases (ICD)-10-AM codes S00 to T75) and having a first external cause of a fall (ICD-10-AM codes W00 to W19). A cluster analysis was performed to identify homogeneous groups using demographic details of patients and information on the presence of comorbidities. Hospital length of stay (LOS) was compared across clusters using competing risks regression. Results Clusters based on area of residence, demographic factors (age, gender, marital status, country of birth) and the presence of comorbidities were identified. Clusters representing hospitalised fallers with comorbidities were associated with longer LOS compared with other cluster groups. Clusters delineated by demographic factors were also associated with increased LOS. Conclusions All patients with comorbidity, and older women without comorbidities, stay in hospital longer following a fall and hence consume a disproportionate share of hospital resources. These findings have important implications for the targeting of falls prevention interventions for community-dwelling older people. PMID:25618735

    Hospital admissions are the source of significant health care expenses, although a large proportion of these admissions can be avoided through proper management of chronic disease. In the present study, we evaluate the impact of a proactive chronic care management program for members of a German insurance society who suffer from chronic disease. Specifically, we tested the impact of nurse-delivered care calls on hospital admission rates. Study participants were insured individuals with coronary artery disease, heart failure, diabetes, or chronic obstructive pulmonary disease who consented to participate in the chronic care management program. Intervention (n  = 17,319) and Comparison (n  = 5668) groups were defined based on records of participating (or not participating) in telephonic interactions. Changes in admission rates were calculated from the year prior to (Base) and year after program commencement. Comparative analyses were adjusted for age, sex, region of residence, and disease severity (stratification of 3 [least severe] to 1 [most severe]). Overall, the admission rate in the Intervention group decreased by 6.2% compared with a 14.9% increase in the Comparison group (P  <  0.001). The overall decrease in admissions for the Intervention group was driven by risk stratification levels 2 and 1, for which admissions decreased by 8.2% and 14.2% compared to Comparison group increases of 12.1% and 7.9%, respectively. Additionally, Intervention group admissions decreased as the number of calls increased (P  =  0.004), indicating a dose-response relationship. These findings indicate that proactive chronic care management care calls can help reduce hospital admissions among German health insurance members with chronic disease.

    Exposure-response relationship between particulate matter less than 10 μm in diameter (PM10) and human health in different seasons from 2001 to 2005 was examined based on hospital admissions data of respiratory system diseases from four major hospitals in Lanzhou, China. To quantify associations of respiratory system diseases with multiple air pollutants and meteorological conditions, a semiparametric generalized additive model was used in the authors' study by implementing daily ambient sulfur dioxide, nitrogen dioxide, and PM10 data collected from the Lanzhou Environmental Monitoring Station and daily meteorological data from Lanzhou Meteorological Bureau. Results showed that daily averaged PM10 increased per interquartile range the hospital admissions number of respiratory diseases by 3.3% in spring, 1.4% in summer, 3.6% in autumn, and 4.0% in winter from a single-pollutant model, or 3.1%, 1.4%, 3.0%, and 4.0% from a multi-pollutant model, respectively. The effect of PM10 on respiratory hospital admissions was lowest in summer and highest in winter. The relative risks of PM10 on female or the elderly (≥ 65 yrs.) were higher, showing a stronger association of PM10 with respiratory diseases in female and elderly groups than in males and people younger than 65.

    Emergency general surgery during hospitalization has not been well characterized. We examined emergency operations remote from admission to identify predictors of postoperative 30-day mortality, postoperative duration of stay >30 days, and complications. Patients >18 years in The American College of Surgeons National Surgical Quality Improvement Program (2011-2014) who had 1 of 7 emergency operations between hospital day 3-18 were included. Patients with operations >95th percentile after admission (>18 days; n = 581) were excluded. Exploratory laparotomy only (with no secondary procedure) represented either nontherapeutic or decompressive laparotomy. Multivariable logistic regression was used to identify predictors of study outcomes. Of 10,093 patients with emergency operations, most were elderly (median 66 years old [interquartile ratio: 53-77 years]), white, and female. Postoperative 30-day mortality was 12.6% (n = 1,275). Almost half the cohort (40.1%) had a complication. A small subset (6.8%) had postoperative duration of stay >30 days. Postoperative mortality after exploratory laparotomy only was particularly high (>40%). In multivariable analysis, an operation on hospital day 11-18 compared with day 3-6 was associated with death (odds ratio 1.6 [1.3-2.0]), postoperative duration of stay >30 days (odds ratio 2.0 [1.6-2.6]), and complications (odds ratio 1.5 [1.3-1.8]). Exploratory laparotomy only also was associated with death (odds ratio 5.4 [2.8-10.4]). Emergency general surgery performed during a hospitalization is associated with high morbidity and mortality. A longer hospital course before an emergency operation is a predictor of poor outcomes, as is undergoing exploratory laparotomy only. Copyright © 2017 Elsevier Inc. All rights reserved.

    Hospitalization of women in latent labour often leads to a cascade of unnecessary intrapartum interventions, to avoid potential disadvantages the recommendation should be to stay at home to improve women's experience and perinatal outcomes. The primary aim of this study was to investigate the association between hospital admission diagnosis (latent vs active phase) and mode of birth. The secondary aim was to explore the relationship between hospital admission diagnosis, intrapartum intervention rates and maternal/neonatal outcomes. A correlational study was conducted in a large Italian maternity hospital. Data from January 2013 to December 2014 were collected from the hospital electronic records. 1.446 records of low risk women were selected. These were dichotomized into two groups based on admission diagnosis: 'latent phase' or 'active phase' of labour. 52.7% of women were admitted in active labour and 47.3% in the latent phase. Women in the latent phase group were more likely to experience a caesarean section or an instrumental birth, artificial rupture of membranes, oxytocin augmentation and epidural analgesia. Admission in the latent phase was associated with higher intrapartum interventions, which were statistically correlated to the mode of birth. Women admitted in the latent phase were more likely to experience intrapartum interventions, which increase the probability of caesarean section. Maternity services should be organized around women and families needs, providing early labour support, to enable women to feel reassured facilitating their admission in labour to avoid the cascade of intrapartum interventions which increases the risk of caesarean section.

    Seizures are listed as an Ambulatory Care Sensitive Condition (ACSC), where, in some cases, hospitalisation may be avoided with appropriate preventative and early management in primary care. We examined the frequencies, trends and financial costs of first and subsequent seizure-related hospital admissions in the adult and paediatric populations, with comparisons to bronchitis/asthma and diabetes admissions in South Australia between 2012 and 2014. De-identified hospital separation data from five major public hospitals in metropolitan South Australia were analysed to determine the number of children and adults admitted for the following Australian Refined Diagnosis Related Groups: seizure related conditions; bronchitis/asthma; and diabetes. Additional data included length of hospital stay and type of admission. Demographic data were analysed to identify whether social determinants influence admission, and a macro costing approach was then applied to calculate the financial costs to the Health Care System. The rate of total seizure hospitalizations was 649 per 100,000; lower than bronchitis/asthma (751/100,000), yet higher than diabetes (500/100,000). The highest proportions of subsequent separations were recorded by children with seizures regardless of complexity (47% +CSCC; 17% -CSCC) compared with asthma (11% +CSCC; 14% -CSCC) or diabetes (14% +CSCC; 13% -CSCC), and by adults with seizures with catastrophic or severe complications/comorbidity (25%), compared with diabetes (22%) or asthma (14%). The mean cost per separation in both children and adults was highest for diabetes (AU$4438/$7656), followed by seizures (AU$2408/$5691) and asthma (AU$2084/$3295). Following the lead of well-developed and resourced health promotion initiatives in asthma and diabetes, appropriate primary care, community education and seizure management services (including seizure clinics) should be targeted in an effort to reduce seizure related hospitalisations which may be avoidable

    Patient-controlled hospital admission for individuals with severe mental disorders is a novel approach in mental healthcare. Patients can admit themselves to a hospital unit for a short stay without being assessed by a psychiatrist or contacting the emergency department. Previous studies assessing the outcomes of patient-controlled hospital admission found trends towards reduction in the use of coercive measures and length of hospital stay; however, these studies have methodological shortcomings and small sample sizes. Larger studies are needed to estimate the effect of patient-controlled hospital admission on the use of coercion and of healthcare services. We aim to recruit at least 315 patients who are offered a contract for patient-controlled hospital admissions in eight different hospitals in Denmark. Patients will be followed-up for at least 1 year to compare the use of coercive measures and of healthcare services, the use of medications and suicidal behaviour. Descriptive statistics will be used to investigate hospitalisations, global assessment of functioning (GAF) and patient satisfaction with treatment. To minimise selection bias, we will match individuals using patient-controlled hospital admission and controls with a 1:5 ratio via a propensity score based on the following factors: sex, age group, primary diagnosis, substance abuse as secondary diagnosis, coercion, number of psychiatric bed days, psychiatric history, urbanity and suicidal behaviour. Additionally, a historical control study will be undertaken in which patients serve as their own control group prior to index date. The study has been approved by The Danish Health and Medicines Authority (j.nr.: 3-3013-934/1/) and by The Danish Data Protection Agency (j.nr.: 2012-58-0004). The study was categorised as a register study by The Danish Health Research Ethics Committee and therefore no further approval was needed (j.nr.: H-2-2014-FSP70).

    Background Studies indicate that a fraction of nursing professionals believe in a “lunar effect”—a purported correlation between the phases of the Earth’s moon and human affairs, such as birth rates, blood loss, or fertility. Purpose This article addresses some of the methodological errors and cognitive biases that can explain the human tendency of perceiving a lunar effect where there is none. Approach This article reviews basic standards of evidence and, using an example from the published literature, illustrates how disregarding these standards can lead to erroneous conclusions. Findings Román, Soriano, Fuentes, Gálvez, and Fernández (2004) suggested that the number of hospital admissions related to gastrointestinal bleeding was somehow influenced by the phases of the Earth’s moon. Specifically, the authors claimed that the rate of hospital admissions to their bleeding unit is higher during the full moon than at other times. Their report contains a number of methodological and statistical flaws that invalidate their conclusions. Reanalysis of their data with proper procedures shows no evidence that the full moon influences the rate of hospital admissions, a result that is consistent with numerous peer-reviewed studies and meta-analyses. A review of the literature shows that birth rates are also uncorrelated to lunar phases. Conclusions Data collection and analysis shortcomings, as well as powerful cognitive biases, can lead to erroneous conclusions about the purported lunar effect on human affairs. Adherence to basic standards of evidence can help assess the validity of questionable beliefs. PMID:25756232

    Although the UK's health and social care system has always been geared towards dealing with crises, evidence suggests that this is becoming increasingly the case. Changes in health care and the prioritisation of scarce resources have resulted in a situation where those with low level needs are often left unsupported until they experience a major life crisis. To rectify this situation, the government has introduced a range of policies designed to emphasise the need for preventive work. Against this background, this paper focuses on the issue of emergency hospital admissions, critiquing the research methodologies that have been used to investigate the scope for preventive work in this area. Despite the use of more sophisticated and objective research tools, there is a need to develop new ways of researching emergency admissions which build on the strengths of existing approaches while at the same time incorporating more of a user perspective.

    Adult hospitals are a common location of adult congenital heart disease (ACHD) admissions, including cardiac surgical admissions. Understanding the patterns and predictors of resource use could aid these institutions by identifying and targeting potentially modifiable determinants of high resource use (HRU). Our objectives were to examine resource use during adult congenital heart surgical admissions in adult hospitals, determine the association of HRU with mortality, and identify risk factors for HRU. Population-based retrospective study We obtained data from the Nationwide Inpatient Sample 2005-2009 and examined ACHD surgical admissions ages 18-49 years (n = 16 231). We defined HRU as admissions with >90th percentile for total hospital charges. Despite representing 10% of admissions, HRU admissions accounted for 32% of total charges. HRU admissions had a higher mortality rate (9.7% vs. 1.8%, P < .001). Multivariable analysis demonstrated that HRU is associated with government insurance adjusted odds ratio (AOR) 2.0 (95% confidence interval [CI] 1.6,2.4), emergency admissions AOR 3.9 (95% CI 3.1,4.8), complications AOR 4.2 (95% CI 3.3,5.2), renal failure AOR 1.8 (95% CI 1.4,2.2), congestive heart failure AOR 1.2 (95% CI 1,1.4), surgical complexity risk category-2 AOR 2.0 (95% CI 1.0,3.6), and category-3+ AOR 2.3 (95% CI 1.4,3.8). HRU admissions for adult congenital heart surgery consumed a disproportionate amount of resources and were associated with higher mortality. HRU risk factors included nonelective admissions, government insurance, heart failure, surgical complexity, renal failure, and complications. Complications, if preventable, may be a target for improvement strategies to decrease resource use. Other risk factors may require a broader patient care approach. © 2014 Wiley Periodicals, Inc.

    The objective of this study was to assess nutritional risk and status of Chinese hospitalized patients at admission and discharge and relations with clinical outcomes. A prospective, nationwide, multicenter study was conducted from June to September 2014 in 34 large hospitals in 18 cities in China. Patients ≥ 18 years with a hospital stay of 7-30 days were recruited. Anthropometric and laboratory indicators, nutritional risk screening, and assessment by Nutritional Risk Screening 2002 (NRS 2002) and subjective global assessment (SGA) were performed within 24 hours of admission and discharge. Clinical data during hospitalization were collected. A total of 6,638 patients met the criteria with a male: female ratio of 1.39:1 and an average age of 59.72 ± 15.40 years. At admission, the proportion of patients with nutritional risk, body mass index (BMI) < 18.5 kg/m 2 , and moderate to severe malnutrition was 40.12%, 8.92%, and 26.45%, respectively, whereas at discharge, these percentages were 42.28%, 8.91%, and 30.57%, respectively. The values of all of these indicators were higher in patients 65 years of age and older. Patients with nutritional risk at admission had a longer average hospital stay (14.02 ± 6.42 vs 13.09 ± 5.703 days), higher incidence of total complications (6.90% vs 1.52%), and greater total medical expenses (3.39 ± 7.50 vs 3.00 ± 3.38 million RMB; all p < 0.01) than patients without nutritional risk. Similar results were obtained for the patients with nutritional risk at discharge. The prevalence of nutritional risk and malnutrition, including moderate to severe malnutrition, at discharge is higher than that observed at admission; the clinical outcome of patients with nutritional risk is poor.

    There are limited data on whether clinical presentation at first heart failure (HF) hospitalization predicts recurrent HF events. We aimed to assess predictors of recurrent HF hospitalizations in mild HF patients with an implantable cardioverter defibrillator or cardiac resynchronization therapy with defibrillator. Data on HF hospitalizations were prospectively collected for patients enrolled in MADIT-CRT. Predictors of recurrent HF hospitalization (HF2) after the first HF hospitalization were assessed using Cox proportional hazards regression models including baseline covariates and clinical presentation or management at first HF hospitalization. There were 193 patients with first HF hospitalization, and 156 patients with recurrent HF events. Recurrent HF rate after the first HF hospitalization was 43% at 1 year, 52% at 2 years, and 55% at 2.5 years. Clinical signs and symptoms, medical treatment, or clinical management of HF at first HF admission was not predictive for HF2. Baseline covariates predicting recurrent HF hospitalization included prior HF hospitalization (HR = 1.59, 95% CI: 1.15-2.20, P = 0.005), digitalis therapy (HR = 1.58, 95% CI: 1.13-2.20, P = 0.008), and left ventricular end-diastolic volume >240 mL (HR = 1.62, 95% CI: 1.17-2.25, P = 0.004). Recurrent HF events are frequent following the first HF hospitalization in patients with implanted implantable cardioverter defibrillator or cardiac resynchronization therapy with defibrillator. Neither clinical presentation nor clinical management during first HF admission was predictive of recurrent HF. Prior HF hospitalization, digitalis therapy, and left ventricular end-diastolic volume at enrolment predicted recurrent HF hospitalization, and these covariates could be used as surrogate markers for identifying a high-risk cohort. © 2017 The Authors.

    Older adults with sarcopenia and malnutrition are at risk for co-morbidities, hospitalization, institutionalization, and mortality. In case of hospitalization, risks may be further increased, especially in case of suboptimal dietary intake. The aim of our study was to assess whether muscle mass, muscle strength, functional performance, and nutritional status at hospital admission were associated with survival and independent living among older patients three months after discharge. The EMPOWER study was an observational, prospective and longitudinal inception cohort of patients older than 70 years admitted to the VU University Medical Centre in Amsterdam, the Netherlands. Patients were assessed for demographic and clinical characteristics, measurements of muscle mass (by bioelectrical impedance analysis), handgrip strength (by dynamometry), functional performance (self-reported ability to walk), and screened for risk of malnutrition (by SNAQ). Three months after hospital discharge, survival and living situation were assessed by a follow-up telephone interview. The majority of the 378 patients enrolled were living independently at the time of hospitalization (90%) and three months post-discharge (83%). Fifty-two patients died in the period from hospital admission to three months after discharge (survival rate 86%). Higher absolute muscle mass measures and not being malnourished at admission were significantly associated with the likelihood of survival. Handgrip strength and self-reported ability to walk were positively associated with a higher chance of living independently three months after discharge, but not with survival. Older patients with greater muscle mass and without malnutrition at hospital admission had a higher survival rate, while measures of muscle strength and functional performance were predictive for living independently three months after hospital discharge. Different components of muscle health relate to different relevant outcomes and therefore

    Several recent studies have reported associations between airborne particles and/or ozone and hospital admissions for respiratory disease. PM[sub 10] has rarely been used as the particle exposure measure, however. This study examined whether such an association could be seen in Minneapolis-St. Paul, Minnesota, which has daily monitoring data for PM[sub 10]. Data on hospital admissions in persons aged 65 y and older were obtained from Medicare records for the years 1986 through 1989. Daily counts of admissions, by admit date, were computed for pneumonia (ICD9 480-487) and chronic obstructive pulmonary disease (COPD) (ICD9 490-496). Classification was by discharge diagnosis. Dailymore » air pollution data from all monitoring stations for ozone and PM[sub 10] in Minneapolis-St. Paul were obtained, and the daily average for each pollutant was computed. An average of approximately six pneumonia admissions and two admissions for chronic obstructive pulmonary disease occurred each day. Poisson regression analysis was used to control for time trends, seasonal fluctuations, and weather. PM[sub 10] was a risk factor for pneumonia admissions (relative risk [RR] = 1.17, 95% confidence interval [CI] = 1.33-1.02) and COPD admissions (RR = 1.57, 95% CI = 2.06-1.20). Ozone was also associated with pneumonia admissions (RR = 1.15, 95% CI = 1.36-0.97). The relative risks are for an increase of 100 [mu]g/m[sup 3] in daily PM[sub 10] and 50 ppb in daily ozone concentration. Several alternative methods for controlling for seasonal patterns and weather were used, including nonparametric regression techniques. The results were not sensitive to the methods. When days exceeding the National Ambient Air Quality Standard for either pollutant were excluded, the association remained for both pneumonia (RR = 1.18, 95% CI = 1.34-1.03 for PM[sub 10] and RR = 1.18, 95% CI = 1.41-0.99 for ozone) and COPD (RR = 1.54, 95% CI = 2.06-1.16 for PM[sub 10]). 48 refs., 6 figs., 5 tabs.« less

    patient management in the acute and sub-acute setting of an Emergency Department is challenging. An assessment of the quality of provided care enables an evaluation of failings. It contributes to the identification of areas for improvement. to obtain an analysis, by hospital-ward physicians, of adult patient care management quality, as well as of the correctness of diagnosis made during emergency admissions. To evaluate the consequences of inadequate patient care management on morbidity, mortality and cost and duration of hospitalization. prospective data analysis obtained between the 1/12/2009 and the 21/12/2009 from physicians using a questionnaire on adult-patient emergency admissions and subsequent hospitalization. questionnaires were completed for 332 patients. Inadequate management of patient care were reported for 73/332 (22 %) cases. Incorrect diagnoses were reported for 20/332 (6 %) cases. 35 cases of inadequate care management (10.5 % overall) were associated with morbidity (34 cases) or mortality (1 case), including 4 cases (1.2 % ) that required emergency intensive-care or surgical interventions. this quality study analyzed the percentage of patient management cases and incorrect diagnoses in the emergency department. The data for serious outcome and wrong diagnosis are comparable with current literature. To improve performance, we consider the process for establishing a diagnosis and therapeutic care.

Since the last decade timing of cholecystectomy is gradually shifting towards the earlier phase of disease and currently gallstone pancreatitis is being evaluated as a further indication for laparoscopic cholecystectomy. There is also great concern regarding compliance of patients for definitive surgery due to poverty, ignorance and illiteracy in developing countries. The aim of this study was to assess the feasibility and safety of laparoscopic cholecystectomy as a definitive treatment in patients with mild and resolving gall stone pancreatitis. This was a prospective study from July 2009 to June 2012. Patients were diagnosed by clinical examination, biochemical tests, ultrasonography and contrast enhanced CT. Patients with mild form of the disease (Ranson Score ≤3) and who showed clinical improvement were offered laparoscopic cholecystectomy in index hospital admission. Those who were unfit for surgery were referred for endoscopic sphincterotomy. Common bile duct stones were excluded preoperatively. A total of 38 patients were admitted with acute gallstone pancreatitis in the study period. The mean age of patients was 46.3 years with male to female ratio of 11/27. 22 (57.8%) patients were selected for laparoscopic cholecystectomy and procedure was completed successfully. Ten (26.3%) patients were referred for ERCP and endoscopic sphincterotomy and 11 (28.9%) were managed by conservative treatment and went without any definitive treatment. Mean duration of time from onset of symptoms and laparoscopic cholecystectomy was 7 days (range 4-10). Mean duration of operative time was 45 minutes and hospital stay was 7 days. There was no operative mortality. No major intra-operative or post-operative complication was recorded. two patients (9%) had minor complications. Laparoscopic cholecystectomy can be safely

    BACKGROUND—The incidence of hospital admissions for respiratory and cardiovascular diseases in areas close to operating coke works in England and Wales was investigated.
METHODS—A small area study using distance from source as a proxy for exposure was undertaken in subjects aged 65 or over and children under 5 years within 7.5 km of four coke works (1991 estimated populations 87 760 and 43 932, respectively). The main outcome measures were emergency hospital admissions in 1992/3-1994/5 with a primary diagnosis of coronary heart disease (ICD 410-414), stroke (ICD 431-438), all respiratory diseases (ICD 460-519), chronic obstructive pulmonary disease (ICD 491-492), and asthma (ICD 493) in those aged 65 or over, and all respiratory and asthma admissions in children under 5 years of age.
RESULTS—At age 65 or over the combined estimate of relative risk with proximity to coke works (per km) ranged from 0.99 (95% CI 0.90to 1.09) for chronic obstructive pulmonary disease to 1.03 (95% CI 0.94 to 1.13) for asthma. For children under 5 years the combined estimate of risk was 1.08 (95% CI 0.98 to 1.20) for all respiratory disease and 1.07 (95% CI 0.98 to 1.18) for asthma. There was evidence of significant heterogeneity in risk estimates between coke work groups, especially in children under 5 years (p<0.001 and p=0.004 for respiratory disease and asthma, respectively). For the Teesside coke works in North East England the relative risk with proximity (per km) was 1.09 (95% CI 1.06 to 1.12) for respiratory disease and 1.09 (95% CI 1.04 to 1.15) for asthma.
CONCLUSIONS—No evidence overall was found for an association between hospital admissions and living near operational coke works in England and Wales. Trends of a higher risk of hospital admission for respiratory disease and asthma among children with proximity to the Teesside plant require further investigation.

    Falls are common among older inpatients and remain a great challenge for hospitals. Despite the relevance of physical impairments to falls, the prognostic value of performance-based functional measures for in-hospital falls and injurious falls remains unknown. This study aimed to determine the predictive ability and accuracy of various functional tests administered at or close to admission in a geriatric hospital to identify in-hospital fallers and injurious fallers. In this prospective study, conducted in a geriatric hospital in Geneva, Switzerland, 807 inpatients (mean age 85.0 years) were subjected to a battery of functional tests administered by physiotherapists within 3 days (interquartile range 1 to 6) of admission, including Short Physical Performance Battery (SPPB), simplified Tinetti, and Timed Up and Go tests. Patients were prospectively followed up for falls and injurious falls until discharge using mandatory standardized incident report forms and electronic patients' records. During a median length of hospital stay of 23 days (interquartile range 14 to 36), 329 falls occurred in 189 (23.4%) patients, including 161 injurious falls of which 24 were serious. In-hospital fallers displayed significantly poorer functional performances at admission on all tests compared with non-fallers (p < 0.001 for all). In multivariate analysis controlling for age, sex, previous falls, and fall as cause of admission, poorer functional performances on all functional tests predicted in-hospital falls and injurious falls (p < 0.001 for all). The SPPB only significantly predicted serious injurious falls (adjusted odds ratio [OR] = 0.76; 95% confidence interval [CI] 0.60-0.96) and fractures (adjusted OR = 0.76; 95% CI 0.59-0.98). In conclusion, poor functional performances, as assessed by SPPB, are independent predictors of in-hospital falls, injurious falls, and fractures in patients admitted to a geriatric hospital. These findings should help to design

    Adolescent deliberate self-harm (DSH) has been found to be associated with a range of bio-psycho-social factors. Simultaneous investigations of these factors enable more robust estimation of the independent effect of a specific risk factor by adjusting for a more complete set of covariates. However, few studies have had the ability to examine all of these factors together. This study used the linkage of population-level de-identified data collections from government agencies to investigate a range of biological, psychological, and social risk factors and their effects on adolescent risk of DSH (with or without suicidal intent). The investigation was undertaken by progressively adjusting for plausible covariates, including fetal growth status and birth order, early familial social factors, parental hospital admissions due to psychiatric disorders or DSH, and parental all-cause death. Conditional logistic regression was used for data analysis. Children's psychiatric history was analysed to examine the extent to which it may account for the link between the risk factors and adolescent DSH risk. This study identified significant biological and perinatal social risk factors for adolescent DSH risk, including overdue birth, high birth order (≥2), single or teen/young motherhood, high neighbourhood socioeconomic disadvantage, and parental psychiatric and/or DSH-related hospital admissions. Further, parental psychiatric and/or DSH-related admissions, and children's psychiatric admissions in particular, largely attenuated the effects of the perinatal social risk factors but not the biological factors on adolescent DSH risk. These results highlight the importance of taking joint actions involving both health and social services in the prevention of adolescent DSH.

    Objective There is limited information on the public health impact of wildfires. The relationship of cardiorespiratory hospital admissions (n = 40 856) to wildfire-related particulate matter (PM2.5) during catastrophic wildfires in southern California in October 2003 was evaluated. Methods Zip code level PM2.5 concentrations were estimated using spatial interpolations from measured PM2.5, light extinction, meteorological conditions, and smoke information from MODIS satellite images at 250 m resolution. Generalised estimating equations for Poisson data were used to assess the relationship between daily admissions and PM2.5, adjusted for weather, fungal spores (associated with asthma), weekend, zip code-level population and sociodemographics. Results Associations of 2-day average PM2.5 with respiratory admissions were stronger during than before or after the fires. Average increases of 70 μg/m3 PM2.5 during heavy smoke conditions compared with PM2.5 in the pre-wildfire period were associated with 34% increases in asthma admissions. The strongest wildfire-related PM2.5 associations were for people ages 65– 99 years (10.1% increase per 10 μg/m3 PM2.5, 95% CI 3.0% to 17.8%) and ages 0–4 years (8.3%, 95% CI 2.2% to 14.9%) followed by ages 20–64 years (4.1%, 95% CI 20.5% to 9.0%). There were no PM2.5–asthma associations in children ages 5–18 years, although their admission rates significantly increased after the fires. Per 10 μg/m3 wildfire-related PM2.5, acute bronchitis admissions across all ages increased by 9.6% (95% CI 1.8% to 17.9%), chronic obstructive pulmonary disease admissions for ages 20–64 years by 6.9% (95% CI 0.9% to 13.1%), and pneumonia admissions for ages 5–18 years by 6.4% (95% CI 21.0% to 14.2%). Acute bronchitis and pneumonia admissions also increased after the fires. There was limited evidence of a small impact of wildfire-related PM2.5 on cardiovascular admissions. Conclusions Wildfire-related PM2.5 led to increased respiratory

    To evaluate national present-on-admission (POA) reporting for hospital-acquired pressure ulcers (HAPUs) and examine the impact of quality measure exclusion criteria on HAPU rates. Medicare inpatient, outpatient, and nursing facility data as well as independent provider claims (2010-2011). Retrospective cross-sectional study. We evaluated acute inpatient hospital admissions among Medicare fee-for-service (FFS) beneficiaries in 2011. Admissions were categorized as follows: (1) no pressure ulcer diagnosis, (2) new pressure ulcer diagnosis, and (3) previously documented pressure ulcer diagnosis. HAPU rates were calculated by varying patient exclusion criteria. Among admissions with a pressure ulcer diagnosis, we observed a large discrepancy in the proportion of admissions with a HAPU based on hospital-reported POA data (5.2 percent) and the proportion with a new pressure ulcer diagnosis based on patient history in billing claims (49.7 percent). Applying quality measure exclusion criteria resulted in removal of 91.2 percent of admissions with a pressure injury diagnosis from HAPU rate calculations. As payers and health care organizations expand the use of quality measures, it is important to consider how the measures are implemented, coding revisions to improve measure validity, and the impact of patient exclusion criteria on provider performance evaluation. © Health Research and Educational Trust.

    Following an emergency medical admission, patients may be admitted an acute medical assessment unit (AMAU) or directly into a ward. An AMAU provides a structured environment for their initial assessment and treatment. All emergency admissions (66,933 episodes in 36,271 patients) to an Irish hospital over an 12-year period (2002-2013) were studied with 30-day in-hospital mortality as the outcome measure. Univariate Odds Ratios, by initial patient allocation, and the fully adjusted Odds Ratios were calculated, using a validated logistic regression model. Patients, by design, were intended to be admitted initially to the AMAU (<= 5 day stay). Capacity constraints dictated that only 39.8% of patients were so admitted; the remainder bypassed the AMAU to a ward (60.2%). All patients remained under the care of the admitting consultant/team. We computed the risk profile for each group, using a multiple variable validated model of 30-day in-hospital mortality; the model indicated the same risk profile between these groups. The univariate OR of an in-hospital death by day 30 for a patient initially allocated to the AMAU, compared with an initial ward allocation was 0.76 (95% CI: 0.71, 0.82- p<0.001). The fully adjusted risk for patients was 0.67 (95% CI: 0.62, 0.73- p<0.001). Patients, with equivalent mortality risk, allocated initially to AMAU or a more traditional ward, appeared to have substantially different outcomes.

    This study investigated the incidence and characteristics of poisoning fatalities and hospital admissions among indigenous Fijians and Indians in Viti Levu, Fiji. Individuals with a mechanism of injury classified as poisoning were identified using the Fiji injury surveillance in hospitals system, a population-based registry established for 12 months in Viti Levu, and analysed using population-based denominators. The mean annual rates of fatalities and hospitalisations were 2.3 and 26.0 per 100 000, respectively. Over two-thirds of poisonings occurred among people of Indian ethnicity. Most intentional poisoning admissions occurred among women (58.3%) and in 15–29-year-old individuals (73.8%). Unintentional poisoning admission rates were highest among Indian boys aged 0–14 years. While over 75% of events occurred at home, the substances involved were not systematically identified. The findings indicate the need for a strategy that addresses the differing contexts across age group, gender and ethnicity, and a lead agency responsible for implementing and monitoring its effectiveness.

    Objective: The purpose of our study was to examine in patients hospitalized with community-acquired pneumonia (CAP) the association between abnormal Paco2 and ICU admission and 30-day mortality. Methods: A retrospective cohort study was conducted at two tertiary teaching hospitals. Eligible subjects were admitted with a diagnosis of CAP. Arterial blood gas analyses were obtained with measurement of Paco2 on admission. Multivariate analyses were performed using 30-day mortality and ICU admission as the dependent measures. Results: Data were abstracted on 453 subjects with a documented arterial blood gas analysis. One hundred eighty-nine patients (41%) had normal Paco2 (35-45 mm Hg), 194 patients (42%) had a Paco2 < 35 mm Hg (hypocapnic), and 70 patients (15%) had a Paco2 > 45 mm Hg (hypercapnic). In the multivariate analysis, after adjusting for severity of illness, hypocapnic patients had greater 30-day mortality (OR = 2.84; 95% CI, 1.28-6.30) and a higher need for ICU admission (OR = 2.88; 95% CI, 1.68-4.95) compared with patients with normal Paco2. In addition, hypercapnic patients had a greater 30-day mortality (OR = 3.38; 95% CI, 1.38-8.30) and a higher need for ICU admission (OR = 5.35; 95% CI, 2.80-10.23). When patients with COPD were excluded from the analysis, the differences persisted between groups. Conclusion: In hospitalized patients with CAP, both hypocapnia and hypercapnia were associated with an increased need for ICU admission and higher 30-day mortality. These findings persisted after excluding patients with CAP and with COPD. Therefore, Paco2 should be considered for inclusion in future severity stratification criteria to appropriate identified patients who will require a higher level of care and are at risk for increased mortality.

    This is an examination of the extent to which patients who are violent in the hospital can be distinguished from nonviolent patients, based on information that is readily available at the time of admission to a state acute psychiatric hospital. The charts of 235 inpatients were examined retrospectively, by selecting 103 patients who had engaged in inpatient violence and comparing them with 132 randomly selected patients who had not during the same period. Data were gathered from initial psychiatric assessment and admissions face sheets in patients' charts, reflecting information available to a mental health professional within the first 24 hours of a patient's admission. Multivariate analysis showed that violent and nonviolent patients were distinguished by diagnosis, age, gender, estimated intelligence, psychiatric history, employment history, living situation, and agitated behavior. These factors led to an 80 percent correct classification of violent patients and thus may assist clinicians to structure decision-making about the risk of inpatient violence.

    Prior studies found higher hospitalization rates among patients with low literacy, but did not determine the preventability of these admissions or consider other determinants of hospitalization, such as social support. This study evaluated whether low literacy was a predictor for preventability of hospitalization when considered in the context of social support, sociodemographics, health status, and risk behaviors. A convenience sample of 400 patients, admitted to general medicine wards in a university-affiliated Veterans Affairs hospital between August 1, 2001 and April 1, 2003, completed a face-to-face interview to assess literacy, sociodemographics, social support, health status, and risk behaviors. Two Board-certified Internists independently assessed preventability of hospitalization and determined the primary preventable cause through blinded medical chart reviews. Neither low literacy (hospitalization. In multivariable analysis, significant predictors of having a preventable cause of hospitalization included binge alcohol drinking (P< or =.001), lower social support for medical care (P<.04), < or =3 annual clinic visits (P<.005), and > or =12 people talked to weekly (P<.023). Among nonbinge drinkers with lower social support for medical care, larger social networks were predictive of preventability of hospitalization. Among nonbinge drinkers with higher support for medical care, lower outpatient utilization was predictive of the preventability of hospitalization. While low literacy was not predictive of admission preventability, the formal assessment of alcohol binge drinking, social support for medical care, social network size, and prior outpatient utilization may enhance our ability to predict the preventability of hospitalizations and develop targeted interventions.

Evaluate the effectiveness of a mixed intervention and reducing the amount and seriousness of acute complications in diabetics from our Health Area. Protocols of action as well as information documents were produced. Diabetes Unit coordinated educational activities in the different support levels of the Area VII of Murcia. Information talks were provided for the people in charge of the Diabetes Unit in every Care Center and Service of the Health Area. Personalized training was provided for patients treated in the different Care levels. The study comprised three stages. Information leaflets were spread and talks offered to the patient regarding in house handling of hypo and hyper glycemia. A reduction of 39% of the emergencies due to acute non complicated diabetes was achieved, as well as a reduction of 47.6% of hospital admissions. There was a reduction of 67.8% of the amount of total hospital stays for the group of patients under 35 years who were admitted into the hospital due to type 1 or 2 diabetes mellitus that didn't show any complications (GRD295). There was a reduction of more than thirty percent in the emergencies due to acute decompensations in the disease and a significant reduction in the avoidable hospital stays in the young adult, thus improving the patients' life quality and reducing the social cost of the diabetic patient.

    To predict the likelihood of hospital-onset Clostridium difficile infection (HO-CDI) based on patient clinical presentations at admission Retrospective data analysis Six US acute care hospitals Adult inpatients We used clinical data collected at the time of admission in electronic health record (EHR) systems to develop and validate a HO-CDI predictive model. The outcome measure was HO-CDI cases identified by a nonduplicate positive C. difficile toxin assay result with stool specimens collected >48 hours after inpatient admission. We fit a logistic regression model to predict the risk of HO-CDI. We validated the model using 1,000 bootstrap simulations. Among 78,080 adult admissions, 323 HO-CDI cases were identified (ie, a rate of 4.1 per 1,000 admissions). The logistic regression model yielded 14 independent predictors, including hospital community onset CDI pressure, patient age ≥65, previous healthcare exposures, CDI in previous admission, admission to the intensive care unit, albumin ≤3 g/dL, creatinine >2.0 mg/dL, bands >32%, platelets ≤150 or >420 109/L, and white blood cell count >11,000 mm3. The model had a c-statistic of 0.78 (95% confidence interval [CI], 0.76-0.81) with good calibration. Among 79% of patients with risk scores of 0-7, 19 HO-CDIs occurred per 10,000 admissions; for patients with risk scores >20, 623 HO-CDIs occurred per 10,000 admissions (P<.0001). Using clinical parameters available at the time of admission, this HO-CDI model demonstrated good predictive ability, and it may have utility as an early risk identification tool for HO-CDI preventive interventions and outcome comparisons.

    The relationship between temperature and subarachnoid hemorrhage (SAH) is less studied than that between temperature and myocardial infarction or other cardiovascular diseases. This study investigated the association between daily temperature and risk of SAH by analyzing the hospital admission records of 111,316 SAH patients from 2004 to 2012 in Korea. A Poisson regression model was used to examine the association between temperature and daily SAH hospital admissions. To analyze data and identify vulnerable groups, we used the following subgroups: sex, age, insurance type, area (rural or urban), and different climate zones. We confirmed a markedly higher SAH risk only for people of low socioeconomic status in both hot and cold temperatures; the relative risk (RR) in the Medicaid group was significantly increased and ranged from 1.04 to 1.11 for cold temperatures and 1.10 to 1.11 for hot temperatures. For the National Health Insurance group, the RR was increased to 1.02 for the maximum temperature only. The increased risk for SAH was highest in the temperate zone. An increase above the heat threshold temperature and a decrease below the cold threshold temperature were correlated with an increased risk of SAH in susceptible populations and were associated with different lag effects and RRs.

    Current scientific information reported that due to successive treatments of schistosomiasis cases in endemic areas of Brazil in the last 30 years, there has been a decrease in severe clinical form (hepatosplenic) and mortality from upper gastrointestinal bleeding due to this disease. Against this information, literature data show that the state of Pernambuco presents significant percentage of deaths and hospitalizations due to schistosomiasis, and occurrence of severe clinical forms as schistosomiasis myeloradiculopathy and persistence of localities with high parasite loads. This scenario justified this research which seeking to update the morbidity and mortality of schistosomiasis in Pernambuco. To conduct a temporal analysis on the evolution of deaths, hospital admissions and severe forms of Manson's schistosomiasis over the last 16 years in Pernambuco, Brazil. It was performed a gathering secondary data on schistosomiasis, from healthcare information systems and from the records of Hospital das Clínicas, Federal University of Pernambuco (HC-UFPE), covering the period from 1999 to 2014. From 1999 to 2013 were registred 2578 deaths due to schistosomiasis and between 2008 and 2014 were recorded 473 hospitalizations for this disease. Among 1999-2014 were identified 1943 cases of schistosomiasis treated at the Hospital das Clínicas of Pernambuco. Among these cases, 72.6% (n. 1411) of the individuals presented the hepatosplenic clinical form (HE), 60.8% (n. 858) were at the age group 30-59 years (adults) and 58% were female. Among the HE cases, 4.6% (n. 58) had ascites, 43.2% (n. 556) had upper gastrointestinal bleeding and 39.1% (n. 489) had collateral circulation. The pattern of fibrosis in the liver E/EC (advanced fibrosis) and F/FC (very advanced fibrosis) occurred in 65.5% (n. 793) of cases. Between 1999-2014 the evolution curve of severe clinical forms of schistosomiasis remained stable, showing a tendency to decline from 2012. When compared to other states

    The prevalence of childhood asthma has increased, although the rate of hospitalization for asthma seems to decrease. In Norway, the rate of hospital admission for childhood asthma from 1984 to 2000 increased. The aim of this study was to assess further trends in hospital admissions for childhood asthma up to 2010. A population-based study including children 1-13 yrs of age hospitalized for asthma during six periods from 1984/1985 to 2009/2010 in Rogaland, Norway, was performed. Medical records from 1536 admissions (1050 children) were studied; and gender, age, number of admissions, length of hospital stay, medications and symptoms were recorded. For all age groups, the rate of admissions per 10.000 increased from 20.1 in 1984/85 to 33.7 in 1989/90, but declined to 14.4 in 2009/2010. Rates were highest in boys (OR 1.87; 95% CI: 1.69, 2.09), younger age groups (OR 2.51; 2.38, 2.64) and decreased from 1984 to 2010 (OR 0.92; 0.88, 0.94). The rates of readmissions were higher than for primary admissions (OR 1.33; 1.19, 1.47). From 1984 to 2010, there was an increased use of inhaled corticosteroids prior to admission (6 to 51%) and started at discharge (7 to 37%), and systemic steroids given during admission (19 to 83%). There has been a substantial decline in the rate of hospital admissions for childhood asthma after 1989/1990, with major differences between age groups and genders. The decline could be due to improved care of children with asthma or a real reduction in asthma exacerbations. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Disease management programs (DMPs) are developed to address the high morbi-mortality and costs of congestive heart failure (CHF). Most studies have focused on intensive programs in academic centers. Washington County Hospital (WCH) in Hagerstown, MD, the primary reference to a semirural county, established a CHF DMP in 2001 with standardized documentation of screening and participation. Linkage to electronic records and state vital statistics enabled examination of the CHF population including individuals participating and those ineligible for the program. All WCH inpatients with CHF International Classification of Diseases, Ninth Revision code in any position of the hospital list discharged alive. Of 4,545 consecutive CHF admissions, only 10% enrolled and of those only 52.2% made a call. Enrollment in the program was related to: age (OR 0.64 per decade older, 95% CI 0.58-0.70), CHF as the main reason for admission (OR 3.58, 95% CI 2.4-4.8), previous admission for CHF (OR 1.14, 95% CI 1.09-1.2), and shorter hospital stay (OR 0.94 per day longer, 95% CI 0.87-0.99). Among DMP participants mortality rates were lowest in the first month (80/1000 person-years) and increased subsequently. The opposite mortality trend occurred in nonenrolled groups with mortality in the first month of 814 per 1000 person-years in refusers and even higher in ineligible (1569/1000 person-years). This difference remained significant after adjustment. Re-admission rates were lower among participants who called consistently (adjusted incidence rate ratio 0.62, 95% CI 0.52-0.77). Only a small and highly select group participated in a low-intensity DMP for CHF in a community-based hospital. Design of DMPs should incorporate these strong selective factors to maximize program impact.

    One of the key climate change factors, temperature, has potentially grave implications for human health. We report the first attempt to investigate the association between the daily 3-hour maximum apparent temperature (Tapp(max)) and respiratory (RD), cardiovascular (CVD), and cerebrovascular (CBD) emergency hospital admissions in Copenhagen, controlling for air pollution. The study period covered 1 January 2002-31 December 2006, stratified in warm and cold periods. A case-crossover design was applied. Susceptibility (effect modification) by age, sex, and socio-economic status was investigated. For an IQR (8°C) increase in the 5-day cumulative average of Tapp(max), a 7% (95% CI: 1%, 13%) increase in the RD admission rate was observed in the warm period whereas an inverse association was found with CVD (-8%, 95% CI: -13%, -4%), and none with CBD. There was no association between the 5-day cumulative average of Tapp(max) during the cold period and any of the cause-specific admissions, except in some susceptible groups: a negative association for RD in the oldest age group and a positive association for CVD in men and the second highest SES group. In conclusion, an increase in Tapp(max) is associated with a slight increase in RD and decrease in CVD admissions during the warmer months.

    Objective To evaluate the validity of the International Classification of Diseases, Tenth Revision (ICD-10) code N17x for acute kidney injury (AKI) in elderly patients in two settings: at presentation to the emergency department and at hospital admission. Design A population-based retrospective validation study. Setting Southwestern Ontario, Canada, from 2003 to 2010. Participants Elderly patients with serum creatinine measurements at presentation to the emergency department (n=36 049) or hospital admission (n=38 566). The baseline serum creatinine measurement was a median of 102 and 39 days prior to presentation to the emergency department and hospital admission, respectively. Main outcome measures Sensitivity, specificity and positive and negative predictive values of ICD-10 diagnostic coding algorithms for AKI using a reference standard based on changes in serum creatinine from the baseline value. Median changes in serum creatinine of patients who were code positive and code negative for AKI. Results The sensitivity of the best-performing coding algorithm for AKI (defined as a ≥2-fold increase in serum creatinine concentration) was 37.4% (95% CI 32.1% to 43.1%) at presentation to the emergency department and 61.6% (95% CI 57.5% to 65.5%) at hospital admission. The specificity was greater than 95% in both settings. In patients who were code positive for AKI, the median (IQR) increase in serum creatinine from the baseline was 133 (62 to 288) µmol/l at presentation to the emergency department and 98 (43 to 200) µmol/l at hospital admission. In those who were code negative, the increase in serum creatinine was 2 (−8 to 14) and 6 (−4 to 20) µmol/l, respectively. Conclusions The presence or absence of ICD-10 code N17× differentiates two groups of patients with distinct changes in serum creatinine at the time of a hospital encounter. However, the code underestimates the true incidence of AKI due to a limited sensitivity. PMID:23204077

    Family physicians play a pivotal role in providing end-of-life care and in enabling terminally ill patients to die in familiar surroundings. The purpose of this study was to explore the family physicians' perceptions of their role and the difficulties they have in preventing and guiding hospital admissions at the end of life. Five focus groups were held with family physicians (N= 39) in Belgium. Discussions were transcribed verbatim and analyzed using a constant comparative approach. Five key roles in preventing and guiding hospital admissions at the end of life were identified: as a care planner, anticipating future scenarios; as an initiator of decisions in acute situations, mostly in an advisory manner; as a provider of end-of-life care, in which competency and attitude is considered important; as a provider of support, particularly by being available during acute situations; and as a decision maker, taking overall responsibility. Family physicians face many different and complex roles and difficulties in preventing and guiding hospital admissions at the end of life. Enhancing the family physician's role as a gatekeeper to hospital services, offering the physicians more end-of-life care training, and developing or expanding initiatives to support them could contribute to a lower proportion of hospital admissions at the end of life. © 2014 Annals of Family Medicine, Inc.

    This study compared the sociodemographic and clinical characteristics and pathways to admission for women admitted to women's crisis houses and to psychiatric hospitals. A women's crisis house is a residential mental health crisis facility for women who would otherwise be considered for voluntary hospital admission. A survey of all 388 female admissions to women's crisis houses and psychiatric hospitals in four boroughs of London during a 12-week period in 2006 was conducted with questionnaires administered to key workers involved in the admissions. Pathways to admission were significantly less complex for women admitted to the crisis houses (fewer preadmission contacts with police, emergency departments, and other services). Women admitted to psychiatric wards were more likely to require supervision or observation. A multivariate analysis of data for the 245 voluntary admissions indicated that women admitted to women's crisis houses were significantly less likely to have a care coordinator (odds ratio [OR]=.528) or to have gone to an accident and emergency department (OR=.214) before admission. No other differences were found between the two groups. Pathways to admission were somewhat different for women admitted to women's crisis houses, but few clinical or sociodemographic differences were found between the two groups. Women's crisis houses may be a viable alternative to traditional wards for voluntary patients not needing intensive supervision and observation. Research should examine whether women's crisis houses are as effective as traditional inpatient services in treating women with acute psychiatric problems.

    Lowering the 30-d re-admission rate after vascular surgery offers the potential to improve healthcare quality. This study evaluated re-admission associated with infections after open and endovascular lower extremity (LE) procedures for peripheral artery disease (PAD). Patients admitted for elective LE procedures for PAD were selected from the Cerner Health Facts ® database. Chi-square analysis evaluated the characteristics of the index admission associated with infection at 30-d re-admission. Multivariable logistic models were created to examine the association of patient and procedural characteristics with infections at re-admission. The microbiology data available at the time of re-admission were evaluated also. A total of 7,089 patients underwent elective LE procedures, of whom 770 (10.9%) were re-admitted within 30 d. A total of 289 (37.5%) had a diagnosis of infection during the re-admission. These infections included surgical site (14.8%), cellulitis (13.6%), sepsis (8.8%), urinary tract (4.9%), and pneumonia (4.9%). Index stay factors associated with infection at re-admission were fluid and electrolyte disorders, kidney disease, diabetes, previous infection, and chronic anemia. Laboratory results associated with an infection during re-admission were post-operative hemoglobin <8 g/dL, blood urea nitrogen >20 mg/dL, platelet counts >400 × 10 3 /mcL, glucose >180 mg/dL, and white blood cell count >11.0 × 10 3 /mcL. Adjusted models demonstrated longer stay, chronic anemia, previous infection, treatment at a teaching hospital, and hemoglobin <8 g/dL to be risk factors for re-admission with infection. Infective organisms isolated during the re-admission stay included Staphylococcus, Enterococcus, Escherichia, Pseudomonas, Proteus, and Klebsiella. Infectious complications were associated with more than one-third of all re-admissions after LE procedures. Predictors of re-admission within 30 d with an infectious complication were longer stay

    Background Over the last decade, the number of foreign citizens (FCs) in Spain has increased. There is no doubt that their health has become a relevant subject from the point of view of public healthcare. Our study aimed to describe hospital admission rates, diagnoses at hospital discharge, and mortality during hospital admissions in FCs from high-income countries (FCHICs), FCs from low-income countries (FCLICs), and autochthonous citizens (ACs). Methods A cross-sectional study was performed at two public hospitals in the city of Alicante (Spain) and its surrounding area. Utilization rates were estimated. Multivariate analysis adjusting for age and sex was performed on hospital admission rates, diagnoses at hospital discharge, service of admission, and mortality during hospital admission in FCHICs and FCLICs compared with ACs (adjusted odds ratio [AOR] with 95% confidence intervals [CI]). Results 42,839 patients ≥15 years were discharged from the hospitals. The utilization rate was lower in FCs than ACs, whose crude rate ratio was 0.676 (95% CI: 0.656-0.696). FCHICs had more risk of being diagnosed at discharge in the categories of the circulatory system (AOR: 1.55; 95% CI: 1.35-1.77), neoplasms (AOR: 1.21; 95% CI: 1.03-1.42), and injury and poisoning (AOR: 1.33; 95% CI: 1.11-1.58). FCLICs had more risk of being diagnosed in the categories of pregnancy, childbirth & puerperium (AOR: 1.33; 95% CI: 1.29-1.59), and injury and poisoning (AOR: 1.19; 95% CI: 1.03-1.36), and less risk in the mental disorder category (AOR: 0.32; 95% CI: 0.22-0.45). The length of hospitalization (in days) was lower in FCLICs (median: 3; IQR: 2–6) than both ACs (median: 4; IQR: 2–8) and FCHICs (median: 4; IQR: 2–8) (p < 0.001). The mortality rates on admission of ACs, FCHICs, and FCLICs were 4.2%, 3.3%, and 1.3%, respectively, but after adjusting for age and sex, the mortality rate risks were similar in FCHICs and FCLICs. Conclusion First, FCs utilized hospitalization less when

    Exacerbations of chronic obstructive pulmonary disease (COPD) are associated with several modifiable (sedentary life-style, smoking, malnutrition, hypoxemia) and non-modifiable (age, co-morbidities, severity of pulmonary function, respiratory infections) risk factors. We hypothesise that most of these risk factors may have a converging and deleterious effects on both respiratory and peripheral muscle function in COPD patients. A multicentre study was carried out in 121 COPD patients (92% males, 63 ± 11 yr, FEV(1), 49 ± 17%pred). Assessments included anthropometrics, lung function, body composition using bioelectrical impedance analysis (BIA), and global muscle function (peripheral muscle (dominant and non-dominant hand grip strength, HGS), inspiratory (PI(max)), and expiratory (PE(max)) muscle strength). GOLD stage, clinical status (stable vs. non-stable) and both current and past hospital admissions due to COPD exacerbations were included as covariates in the analyses. Respiratory and peripheral muscle weakness were observed in all subsets of patients. Muscle weakness, was significantly associated with both current and past hospitalisations. Patients with history of multiple admissions showed increased global muscle weakness after adjusting by FEV(1) (PE(max), OR = 6.8, p < 0.01; PI(max), OR = 2.9, p < 0.05; HGSd, OR = 2.4, and HGSnd, OR = 2.6, p = 0.05). Moreover, a significant increase in both respiratory and peripheral muscle weakness, after adjusting by FEV(1), was associated with current acute exacerbations. Muscle dysfunction, adjusted by GOLD stage, is associated with an increased risk of hospital admissions due to acute episodes of exacerbation of the disease. Current exacerbations further deteriorate muscle dysfunction. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Little is known about the population-based burden of ED care for COPD. We analyzed statewide ED surveillance system data to quantify the frequency of COPD-related ED visits, hospital admissions, and comorbidities. In 2008 to 2009 in North Carolina, 97,511 COPD-related ED visits were made by adults ≥ 45 years of age, at an annual rate of 13.8 ED visits/1,000 person-years. Among patients with COPD (n = 33,799), 7% and 28% had a COPD-related return ED visit within a 30- and 365-day period of their index visit, respectively. Compared with patients on private insurance, Medicare, Medicaid, and noninsured patients were more likely to have a COPD-related return visit within 30 and 365 days and have three or more COPD-related visits within 365 days. There were no differences in return visits by sex. Fifty-one percent of patients with COPD were admitted to the hospital from the index ED visit. Subsequent hospital admission risk in the cohort increased with age, peaking at 65 to 69 years (risk ratio [RR], 1.41; 95% CI, 1.26-1.57); there was no difference by sex. Patients with congestive heart failure (RR, 1.29; 95% CI, 1.22-1.37), substance-related disorders (RR, 1.35; 95% CI, 1.13-1.60), or respiratory failure/supplemental oxygen (RR, 1.25; 95% CI, 1.19-1.31) were more likely to have a subsequent hospital admission compared with patients without these comorbidities. The population-based burden of COPD-related care in the ED is significant. Further research is needed to understand variations in COPD-related ED visits and hospital admissions.

    Clock drawing is a quick, easy to remember test that is well received by patients. It is a good screening test for Alzheimer's disease in the outpatient setting. We evaluated its usefulness compared with the standard Mini Mental State Examination (MMSE) in elderly acute medical and surgical hospital admissions. Within 48 hours of admission, 117 patients over 70 years old were administered the MMSE and asked to draw a clock. Using the MMSE as the standard, clock drawing had a sensitivity of 77% and a specificity of 87%. Patients with discrepant scores were then further evaluated. The findings suggest that normal clock drawing ability reasonably excludes cognitive impairment or other causes of an abnormal MMSE in elderly acute medical and surgical hospital admissions, where cognitive impairment is common and frequently missed.

    U.S. Hispanics, now the single largest minority group in the country, face unique mental health disparities. The current study utilizes Andersen's Behavioral Model of Health Service Use to examine ethnic disparities in receiving a schizophrenia or mood disorder diagnosis at psychiatric hospital admission. Our retrospective cohort study examined electronic health record data at an academic safety-net psychiatric hospital for adult patients (n = 5571) admitted between 2010 and 2013. Logistic regression with block-wise entry of predisposing, enabling and need variables was used to examine ethnic disparities in receiving a schizophrenia diagnosis at admission. The block of need factors was the strongest predictor of receiving a schizophrenia diagnosis compared to predisposing and enabling factors. Compared to non-Hispanic whites, Hispanics and African Americans had a greater likelihood of receiving a schizophrenia diagnosis at admission. Additionally, patients diagnosed with schizophrenia had elevated positive and negative symptoms and were more likely to be male, single/unmarried, homeless, high inpatient service utilizers, involuntarily hospitalized, and to exhibit functional impairment at psychiatric hospital admission. To address elevated positive and negative symptoms of schizophrenia, functional impairment, social withdrawal, and high inpatient service utilization, promising psychosocial interventions should be adapted for racial and ethnic minority populations and utilized as an adjuvant to antipsychotic medication.

    Healthy Outlook is a service delivered by the UK Met Office directly to patients with chronic obstructive pulmonary disease (COPD) that has been in place since 2006. Its objective is to reduce the severity and length of COPD exacerbations, hence improving the quality of life and life expectancy. To assess the effect of the Healthy Outlook service on hospital admission rates of all general practitioners that have used the service. Control practices were selected for each of the 661 participating practices. The number of hospital admissions for each practice was extracted from the Hospital Episode Statistics database. The differences in admission rates per practice between the first year of use of the Healthy Outlook service and the previous year were compared by paired t-test analyses. For admissions with a primary diagnosis of COPD, the difference between participating and control practices was -0.8% (95% confidence interval (CI)=-1.8 to 0.2%; P=0.13). For admissions with a primary or co-morbid diagnosis of COPD, the difference was -2.3% (95% CI=-4.2 to -0.4%; P=0.02). Participation in the Healthy Outlook service reduces hospital admission rates for patients coded on discharge with COPD (including co-morbid).

    The Quality and Outcomes Framework, or QOF, rewards primary care doctors (GPs) in the UK for providing certain types of care. Since 2006, GPs have been paid to identify patients with dementia and to conduct an annual review of their mental and physical health. During the review, the GP also assesses the carer's support needs, including impact of caring, and ensures that services are co-ordinated across care settings. In principle, this type of care should reduce the risk of admission to long-term residential care directly from an acute hospital ward, a phenomenon considered to be indicative of poor quality care. However, this potential effect has not previously been tested. Using English data from 2006/07 to 2010/11, we ran multilevel logit models to assess the impact of the QOF review on the risk of care home placement following emergency admission to acute hospital. Emergency admissions were defined for (a) people with a primary diagnosis of dementia and (b) people with dementia admitted for treatment of an ambulatory care sensitive condition. We adjusted for a wide range of potential confounding factors. Over the study period, 19% of individuals admitted to hospital with a primary diagnosis of dementia (N = 31,120) were discharged to a care home; of those admitted for an ambulatory care sensitive condition (N = 139,267), the corresponding figure was 14%. Risk factors for subsequent care home placement included older age, female gender, vascular dementia, incontinence, fall, hip fracture, and number of comorbidities. Better performance on the QOF review was associated with a lower risk of care home placement but only when the admission was for an ambulatory care sensitive condition. The QOF dementia review may help to reduce the risk of long-term care home placement following acute hospital admission.

  13. Visa refusal following compulsory hospital admission under the Mental Health Act 1983 (England and Wales): fact or fiction?

    2015-08-01

    Historically, compulsory hospital admission led to discrimination for service users. For example, until recently detention under the Mental Health Act 1983 (England and Wales) would disqualify a person from being a Member of Parliament. There is a belief among mental health professionals that compulsory hospital admission will result in service users being refused a tourist visa. However, there is a paucity of literature on this topic, particularly from an international perspective. Based on the information reviewed in this study, there is no evidence to support this belief. Of 262 travel destinations, 96 (36.6%) require British citizens to obtain a tourist visa. Six (2.3%) destinations require applicants to declare a mental health condition in order to obtain a tourist visa. None of these destinations ask applicants to declare a history of compulsory hospital admission. However, the possibility exists that anyone declaring a mental health problem may be asked to provide further information about their condition before a visa is granted. Mental health nurses require education to ensure that their knowledge of mental health legislation is up to date. This education should include information on the potential consequences of compulsory hospital admission for the service user's social life following discharge. Service users and their families should be provided with written information on the potential social impact of detention along with a list of organizations that can provide advice on specific issues. This study sought to establish whether a history of compulsory hospital admission prevented a person from obtaining a tourist visa. A visa application form and/or other relevant information were obtained for 262 travel destinations visited by British citizens. Ninety-six (36.6%) destinations require British citizens to obtain a tourist visa. All visas are issued subject to travellers meeting a number of conditions, for example being in possession of travel insurance

    Background Rates of death from cardiovascular and cerebrovascular diseases have been steadily declining over the past few decades. Whether such declines are occurring to a similar degree for common disorders such as acute myocardial infarction, heart failure and stroke is uncertain. We examined recent national trends in mortality and rates of hospital admission for these 3 conditions. Methods We analyzed mortality data from Statistic Canada’s Canadian Mortality Database and data on hospital admissions from the Canadian Institute for Health Information’s Hospital Morbidity Database for the period 1994–2004. We determined age- and sex-standardized rates of death and hospital admissions per 100 000 population aged 20 years and over as well as in-hospital case-fatality rates. Results The overall age- and sex-standardized rate of death from cardiovascular disease in Canada declined 30.0%, from 360.6 per 100 000 in 1994 to 252.5 per 100 000 in 2004. During the same period, the rate fell 38.1% for acute myocardial infarction, 23.5% for heart failure and 28.2% for stroke, with improvements observed across most age and sex groups. The age- and sex-standardized rate of hospital admissions decreased 27.6% for stroke and 27.2% for heart failure. The rate for acute myocardial infarction fell only 9.2%. In contrast, the relative decline in the inhospital case-fatality rate was greatest for acute myocardial infarction (33.1%; p < 0.001). Much smaller relative improvements in case-fatality rates were noted for heart failure (8.1%) and stroke (8.9%). Interpretation The rates of death and hospital admissions for acute myocardial infarction, heart failure and stroke in Canada changed at different rates over the 10-year study period. Awareness of these trends may guide future efforts for health promotion and health care planning and help to determine priorities for research and treatment. PMID:19546444

    Objectives To examine links between clinical and other characteristics of people with Alzheimer's disease living in the community, likelihood of care home or hospital admission, and associated costs. Design Observational data extracted from clinical records using natural language processing and Hospital Episode Statistics. Statistical analyses examined effects of cognition, physical health, mental health, sociodemographic factors and living circumstances on risk of admission to care home or hospital over 6 months and associated costs, adjusting for repeated observations. Setting Catchment area for South London and Maudsley National Health Service Foundation Trust, provider for 1.2 million people in Southeast London. Participants Every individual with diagnosis of Alzheimer's disease seen and treated by mental health services in the catchment area, with at least one rating of cognition, not resident in care home at time of assessment (n=3075). Interventions Usual treatment. Main outcome measures Risk of admission to, and days spent in three settings during 6-month period following routine clinical assessment: care home, mental health inpatient care and general hospital inpatient care. Results Predictors of probability of care home or hospital admission and/or associated costs over 6 months include cognition, functional problems, agitation, depression, physical illness, previous hospitalisations, age, gender, ethnicity, living alone and having a partner. Patterns of association differed considerably by destination. Conclusions Most people with dementia prefer to remain in their own homes, and funding bodies see this as cheaper than institutionalisation. Better treatment in the community that reduces health and social care needs of Alzheimer's patients would reduce admission rates. Living alone, poor living circumstances and functional problems all raise admission rates, and so major cuts in social care budgets increase the risk of high-cost admissions which older

    The postcode (where the home is situated) is an indicator of socioeconomic status and is associated with morbidity, mortality, and the use of health services. The aim of this study was to analyse its effects on paediatric admissions and to determine the rates of the most common causes of paediatric admissions in Seville. An observational cross-sectional study with two analysis units: under 15 year-old "admissions" in public hospitals in Seville (n=2,660) and "city districts" of Seville (n=11). The independent variable analysed was whether the postcode of the admitted patients was within a Regional Government designated "area with social transformation needs". The analysis of the admissions was performed using X 2 -test, Fisher test and Student-t test, with the description of rates using the calculation of crude and specific rates, and by rate ratio. Children living in districts with a lower socioeconomic status were on average 7 months younger (P<.001), and they were significantly more likely to be admitted via the emergency department (P<.001). There was no statistical difference detected in either the length of hospital stay or mortality. The crude admission rate ratio was higher in districts with a lower socioeconomic status (1.8), with a higher specific rate ratio detected in admissions due to asthma, respiratory infections, inguinal hernia, and epilepsy/convulsions. Paediatric hospital admission rates of the main diagnoses were higher in districts with a lower socioeconomic status. Children living in these districts were more likely to be admitted younger and via the emergency department. Copyright © 2016 Asociación Española de Pediatría. Publicado por Elsevier España, S.L.U.

    In most midlatitude locations, human morbidity and mortality are highly seasonal, with winter peaks driven by respiratory disease and associated comorbidities. But the transition between high and low mortality/morbidity months varies spatially. We use a measure of the thermal biophysical strain imposed on the respiratory system—the Acclimatization Thermal Strain Index (ATSI)—to examine respiratory hospital admissions in Charlottesville, VA. Daily respiratory admissions to the University of Virginia over a 19-year period are compared to ATSI values derived from hourly surface weather data acquired from the Charlottesville airport. Negative ATSI values (associated with transitions from warm (and humid) to cold (and dry) conditions) are related to admission peaks at seasonal and weekly timescales, whereas positive ATSI values (cold to warm) exhibit weaker relationships. This research marks the first application of the ATSI to human morbidity, and results suggest that respiratory strain may account for how people who are acclimated to different climates respond to short-term weather changes.

    A subgroup of patients admitted to the hospital with a diagnosis of community-acquired pneumonia (CAP) have received antibiotic therapy prior to admission for the current episode of pneumonia. The objective of this study was to assess the clinical course of patients receiving antibiotics prior to admission, compared to patients not previously treated. An observational cohort of 3364 CAP patients consecutively admitted to our hospital, and prospectively included, were studied. We collected clinical, microbiological and biochemical parameters, focusing on recent antibiotics received prior to admission. 610 (18%) patients received antibiotics prior to hospital admission for the current CAP episode. Patients with previous antibiotic use developed septic shock less frequently (4% vs. 7%, p = 0.007) and required invasive ventilation less often (3% vs. 6%, p = 0.002). After adjustment by different covariate factors and propensity score, antibiotic therapy was still independently associated with a lower incidence of septic shock at admission (OR 0.54 [95% CI 0.31-0.95], p = 0.03) and less need for invasive ventilation (OR 0.38 [95% CI 0.16-0.91], p = 0.03). In this cohort, recent use of antibiotics before hospital admission in CAP seems to be associated with a lower incidence of septic shock on admission and a lower need for invasive ventilation.

    To investigate the association between ambient air pollution and hospital emergency admissions in Beijing. In this study, a semi-parametric generalized additive model (GAM) was used to evaluate the specific influences of air pollutants (PM10, SO2, and NO2) on hospital emergency admissions with different lag structures from 2009 to 2011, the sex and age specific influences of air pollution and the modifying effect of seasons on air pollution to analyze the possible interaction. It was found that a 10 μg/m3 increase in concentration of PM10 at lag 03 day, SO2 and NO2 at lag 0 day were associated with an increase of 0.88%, 0.76%, and 1.82% respectively in overall emergency admissions. A 10 μg/m3 increase in concentration of PM10, SO2 and NO2 at lag 5 day were associated with an increase of 1.39%, 1.56%, and 1.18% respectively in cardiovascular disease emergency admissions. For lag 02, a 10 μg/m3 increase in concentration of PM10, SO2 and NO2 were associated with 1.72%, 1.34%, and 2.57% increases respectively in respiratory disease emergency admissions. This study further confirmed that short-term exposure to ambient air pollution was associated with increased risk of hospital emergency admissions in Beijing.

    Heat exposure is known to have a complex set of physiological effects on multiple organ systems, but current understanding of the health effects is mostly based on studies investigating a small number of prespecified health outcomes such as cardiovascular and respiratory diseases. To identify possible causes of hospital admissions during extreme heat events and to estimate their risks using historical data. Matched analysis of time series data describing daily hospital admissions of Medicare enrollees (23.7 million fee-for-service beneficiaries [aged ≥65 years] per year; 85% of all Medicare enrollees) for the period 1999 to 2010 in 1943 counties in the United States with at least 5 summers of near-complete (>95%) daily temperature data. Heat wave periods, defined as 2 or more consecutive days with temperatures exceeding the 99th percentile of county-specific daily temperatures, matched to non-heat wave periods by county and week. Daily cause-specific hospitalization rates by principal discharge diagnosis codes, grouped into 283 disease categories using a validated approach. Risks of hospitalization for fluid and electrolyte disorders, renal failure, urinary tract infection, septicemia, and heat stroke were statistically significantly higher on heat wave days relative to matched non-heat wave days, but risk of hospitalization for congestive heart failure was lower (P < .05). Relative risks for these disease groups were 1.18 (95% CI, 1.12-1.25) for fluid and electrolyte disorders, 1.14 (95% CI, 1.06-1.23) for renal failure, 1.10 (95% CI, 1.04-1.16) for urinary tract infections, 1.06 (95% CI, 1.00-1.11) for septicemia, and 2.54 (95% CI, 2.14-3.01) for heat stroke. Absolute risk differences were 0.34 (95% CI, 0.22-0.46) excess admissions per 100,000 individuals at risk for fluid and electrolyte disorders, 0.25 (95% CI, 0.12-0.39) for renal failure, 0.24 (95% CI, 0.09-0.39) for urinary tract infections, 0.21 (95% CI, 0.01-0.41) for septicemia, and 0.16 (95% CI, 0

    In May, 2012, Rwanda became the first low-income African country to introduce pentavalent rotavirus vaccine into its routine national immunisation programme. Although the potential health benefits of rotavirus vaccination are huge in low-income African countries that account for more than half the global deaths from rotavirus, concerns remain about the performance of oral rotavirus vaccines in these challenging settings. We conducted a time-series analysis to examine trends in admissions to hospital for non-bloody diarrhoea in children younger than 5 years in Rwanda between Jan 1, 2009, and Dec 31, 2014, using monthly discharge data from the Health Management Information System. Additionally, we reviewed the registries in the paediatric wards at six hospitals from 2009 to 2014 and abstracted the number of total admissions and admissions for diarrhoea in children younger than 5 years by admission month and age group. We studied trends in admissions specific to rotavirus at one hospital that had undertaken active rotavirus surveillance from 2011 to 2014. We assessed changes in rotavirus epidemiology by use of data from eight active surveillance hospitals. Compared with the 2009-11 prevaccine baseline, hospital admissions for non-bloody diarrhoea captured by the Health Management Information System fell by 17-29% from a pre-vaccine median of 4051 to 2881 in 2013 and 3371 in 2014, admissions for acute gastroenteritis captured in paediatric ward registries decreased by 48-49%, and admissions specific to rotavirus captured by active surveillance fell by 61-70%. The greatest effect was recorded in children age-eligible to be vaccinated, but we noted a decrease in the proportion of children with diarrhoea testing positive for rotavirus in almost every age group. The number of admissions to hospital for diarrhoea and rotavirus in Rwanda fell substantially after rotavirus vaccine implementation, including among older children age-ineligible for vaccination, suggesting

    Objective It is well recognised that variation in the geographical distribution of multiple sclerosis (MS) exists. Early studies in England have shown the disease to have been more common in the North than the South. However, this could be an artefact of inaccurate diagnosis and ascertainment, and recent data on MS prevalence are lacking. In the present study, data were analysed to provide a more contemporary map of the distribution of MS in England and, as infectious mononucleosis (IM) has been shown to be associated with the risk of MS, the geographical distribution of IM with that of MS was compared. Methods Analysis of linked statistical abstracts of hospital data for England between 1999 and 2005. Results There were 56 681 MS patients. The admission rate for MS was higher in females (22/105; 95% CI 21.8 to 22.3) than males (10.4/105; 95% CI 10.2 to 10.5). The highest admission rate for MS was seen for residents of Cumbria and Lancashire (North of England) (20.1/105; 95% CI 19.3 to 20.8) and the lowest admission rate was for North West London residents (South of England) (12.4/105; 95% CI 11.8 to 13.1). The geographical distributions of IM and MS were significantly correlated (weighted regression coefficient (r (w))=0.70, p<0.0001). Admission rates for MS were lowest in the area quintile with the highest level of deprivation and they were also lowest in the area quintile with the highest percentage of population born outside the UK. A significant association between northernliness and MS remained after adjustment for deprivation and UK birthplace. Conclusions The results show the continued existence of a latitude gradient for MS in England and show a correlation with the distribution of IM. The data have implications for healthcare provision, because lifetime costs of MS exceed £1 million per case in the UK, as well as for studies of disease causality and prevention. PMID:21212107

    Infections are a major cause of morbidity and mortality in systemic lupus erythematosus. Clinical outcomes of systemic lupus erythematosus patients hospitalized due to infections vary among different ethnic populations. Thus, we determined the outcomes and associated factors in a group of Hispanics from Puerto Rico with systemic lupus erythematosus admitted due to severe infections. Records of systemic lupus erythematosus patients admitted to the Adult University Hospital, San Juan, Puerto Rico, from January 2006 to December 2014 were examined. Demographic parameters, lupus manifestations, comorbidities, pharmacologic treatments, inpatient complications, length of stay, readmissions, and mortality were determined. Patients with and without infections were compared using bivariate and multivariate analyses. A total of 204 admissions corresponding to 129 systemic lupus erythematosus patients were studied. The mean (standard deviation) age was 34.7 (11.6) years; 90% were women. The main causes for admission were lupus flare (45.1%), infection (44.0%), and initial presentation of systemic lupus erythematosus (6.4%). The most common infections were complicated urinary tract infections (47.0%) and soft tissue infections (42.0%). In the multivariate analysis, patients admitted with infections were more likely to have diabetes mellitus (odds ratio: 4.20, 95% confidence interval: 1.23-14.41), exposure to aspirin prior to hospitalization (odds ratio: 4.04, 95% confidence interval: 1.03-15.80), and higher mortality (odds ratio: 6.00, 95% confidence interval: 1.01-35.68) than those without infection. In this population of systemic lupus erythematosus patients, 44% of hospitalizations were due to severe infections. Patients with infections were more likely to have diabetes mellitus and higher mortality. Preventive and control measures of infection could be crucial to improve survival in these patients.

    Fluid, electrolytes and acid base disturbances are responsible for most deaths due to acute diarrhoea. The aim of this study is to describe the point-of-admission serum electrolyte profile of children with dehydration due to acute diarrhoea. In this cross-sectional study, the serum electrolyte levels of 185 children with dehydration due to acute diarrhoea were assessed at the point of admission at the Diarrhoea Treatment and Training Unit of the University of Benin Teaching Hospital. The age of the study population ranged from 29 days to 59 months. Out of a total of 185 subjects, 30 (16.2%), 114 (61.6%), and 41 (22.2%) had severe, moderate and mild dehydration, respectively. In addition, hyponatraemic dehydration was the most common type of dehydration, accounting for 60.5% of cases. Metabolic acidosis and hypokalaemia occurred in 59.5% and 44.3% of cases, respectively. Only the serum bicarbonate level was significantly affected by degree of dehydration (p = 0.001). Age of more than 12 months and presence of vomiting were significantly associated with hyponatraemia (p = 0.005 & p = 0.02), while age of less than or equal 12 months and absence of vomiting were associated with metabolic acidosis (p = 0.04 & p = 0.03). The degree of dehydration appears to be a good predictor of the occurrence of metabolic acidosis while age is a risk factor for hyponatraemia and metabolic acidosis.

    In many regions of the world, climatic change is associated with increased extreme temperatures, which can have severe effects on mortality and morbidity. In this study, we examine the effect of extreme weather on hospital admissions in Cyprus, for inland and coastal areas, through the use of synoptic weather classifications (air mass types). In addition, the effect of particulate air pollution (PM10) on morbidity is examined. Our results show that two air mass types, namely (a) warm, rainy days with increased levels of water vapour in the atmosphere and (b) cold, cloudy days with increased levels of precipitation, were associated with increased morbidity in the form of hospital admissions. This was true both for cardiovascular and respiratory conditions, for all age groups, but particularly for the elderly, aged over 65. Particulate air pollution was also associated with increased morbidity in Cyprus, where the effect was more pronounced for cardiovascular diseases. Copyright © 2015 Elsevier B.V.

    Hospitalisations are associated with ambient temperature, but little is known about responses in population sub-groups. In this study, heat responses for Indigenous and non-Indigenous people in two age groups were examined for two categories of cardiac diseases using daily hospital admissions from five Northern Territory hospitals (1992–2011). Admission rates during the hottest five per cent of days and the coolest five per cent of days were compared with rates at other times. Among 25–64 year olds, the Indigenous female population was more adversely affected by very hot days than the non-Indigenous female population, with admission rates for ischaemic heart disease (IHD) increasing by 32%. People older than 65 were more sensitive to cold, with non-Indigenous male admissions for heart failure increasing by 64%, and for IHD by 29%. For older Indigenous males, IHD admissions increased by 52% during cold conditions. For older non-Indigenous females, increases in admissions for heart failure were around 50% on these cold days, and 64% for older Indigenous females. We conclude that under projected climate change conditions, admissions for IHD amongst younger Indigenous people would increase in hot conditions, while admissions among elderly people during cold weather may be reduced. The responses to temperature, while showing significant relationships across the Northern Territory, may vary by region. These variations were not explored in this assessment. PMID:24531121

    Abstract The public sector scale-up of antiretroviral therapy (ART) in South Africa commenced in 2004. We aimed to describe the hospital-level disease burden and factors contributing to morbidity and mortality among hospitalized HIV-positive patients in the era of widespread ART availability. Between June 2012 and October 2013, unselected patients admitted to medical wards at a public sector district hospital in Cape Town were enrolled in this cross-sectional study with prospective follow-up. HIV testing was systematically offered and HIV-infected patients were systematically screened for TB. The spectrum of admission diagnoses among HIV-positive patients was documented, vital status at 90 and 180 days ascertained and factors independently associated with death determined. Among 1018 medical admissions, HIV status was ascertained in 99.5%: 60.1% (n = 609) were HIV-positive and 96.1% (n = 585) were enrolled. Of these, 84.4% were aware of their HIV-positive status before admission. ART status was naive in 35.7%, current in 45.0%, and interrupted in 19.3%. The most frequent primary clinical diagnoses were newly diagnosed TB (n = 196, 33.5%), other bacterial infection (n = 100, 17.1%), and acquired immunodeficiency syndrome (AIDS)-defining illnesses other than TB (n = 64, 10.9%). By 90 days follow-up, 175 (29.9%) required readmission and 78 (13.3%) died. Commonest causes of death were TB (37.2%) and other AIDS-defining illnesses (24.4%). Independent predictors of mortality were AIDS-defining illnesses other than TB, low hemoglobin, and impaired renal function. HIV still accounts for nearly two-thirds of medical admissions in this South African hospital and is associated with high mortality. Strategies to improve linkage to care, ART adherence/retention and TB prevention are key to reducing HIV-related hospitalizations in this setting. PMID:26683950

    While the most obvious impact of burn is on the skin, systemic responses also occur after burn, including intestinal inflammation. The objective of this study was to assess if burns are associated with increased long-term admissions for gastrointestinal diseases. A population-based longitudinal study using linked hospital morbidity and death data from Western Australia was undertaken of adults aged at least 15 years when hospitalized for a first burn (n=20,561) in 1980-2012. A frequency matched non-injury comparison cohort was randomly selected from Western Australia's birth registrations and electoral roll (n=80,960). Crude admission rates and summed days in hospital for digestive diseases were calculated. Negative binomial and Cox proportional hazards regression modeling were used to generate incidence rate ratios (IRR) and hazard ratios (HR), respectively. After adjustment for demographic factors and pre-existing health status, the burn cohort had 1.54 times (95% confidence interval (CI): 1.47-1.62) as many admissions and almost three times the number of days in hospital with a digestive system diagnosis (IRR, 95% CI: 2.90, 2.60-3.25) than the uninjured cohort. Significantly elevated adjusted post-burn incident rates were identified, with the risk decreasing with increasing time: in the first month (HR, 95% CI: 3.02, 1.89-4.82), from one month to five years (HR, 95% CI: 1.42, 1.31-1.54), and from five to twenty years after burn (HR, 95% CI: 1.13, 1.06-1.20). Findings of increased hospital admission rates and prolonged length of hospital stay for gastrointestinal diseases in the burn cohort provide evidence to support that burns have effects that persist long after the initial injury.

    Leptospirosis is a worldwide zoonotic disease. Risk factors for the disease may vary among countries. This study was conducted to determine the risk factors of leptospirosis among febrile cases. A hospital-based cross-sectional study was conducted among 999 febrile patients admitted to 10 hospitals in northeastern Malaysia, from August 2010 to February 2011. An interviewer-guided proforma sheet on sociodemography, type of occupation and social history data was distributed to all adult patients with fever on admission. Serum sample for leptospirosis was screened by IgM Enzyme-linked Immunosorbent Assay (IgM ELISA) test and confirmed by Microscopic Agglutination Test (MAT). The cut-off point for positive MAT was ≥ 1:400 titer in single acute specimens. Seroprevalence of leptospirosis was 8.4% (95% CI: 6.8, 10.3) (n=84/999) by MAT. Multiple logistic regression analysis showed that the high risk occupation group (OR: 1.95, 95% CI: 1.22, 3.13) (p=0.005) and history of recent recreational activity (OR: 2.36, 95% CI: 1.46, 3.85) (p<0.001) were significant associated factors for leptospirosis. This study shows a relatively high seroprevalence of leptospirosis in northeastern Malaysia. Identification of high risk occupational group and history of recent recreational activity will help to increase the index of suspicion to diagnose leptospirosis among febrile inpatients due to its mimicking other common febrile illnesses in Malaysia.

    In 2010, the AIDS Study Group (Grupo de Estudio del SIDA [GESIDA]) developed 66 quality care indicators. The aim of this study is to determine which of these indicators are associated with mortality and hospital admission, and to perform a preliminary assessment of a prediction rule for mortality and hospital admission in patients on treatment and follow-up. A retrospective cohort study was conducted in the Hospital Universitario Son Espases (Palma de Mallorca, Spain). Eligible participants were patients with human immunodeficiency syndrome≥18 years old who began follow-up in the Infectious Disease Section between 1 January 2000 and 31 December 2012. A descriptive analysis was performed to evaluate anthropometric variables, and a logistic regression analysis to assess the association between GESIDA indicators and mortality/admission. The mortality probability model was built using logistic regression. A total of 1,944 adults were eligible (median age: 37 years old, 78.8% male). In the multivariate analysis, the quality of care indicators associated with mortality in the follow-up patient group were the items 7, 16 and 20, and in the group of patients on treatment were 7, 16, 20, 35, and 38. The quality of care indicators associated with hospital admissions in the follow-up patients group were the same as those in the mortality analysis, plus number 31. In the treatment group the associated quality of care indicators were items 7, 16, 20, 35, 38, and 40. Some GeSIDA quality of care indicators were associated with mortality and/or hospital admissions. These indicators are associated with delayed diagnosis, regular monitoring, prevention of infections, and control of comorbidities.

    The variable effectiveness of clinical asthma pathways to reduce hospital admissions may be explained in part by the timing of systemic corticosteroid administration. We examine the effect of early (within 60 minutes [SD 15 minutes] of triage) versus delayed (>75 minutes) administration of systemic corticosteroids on health outcomes. We conducted a prospective observational cohort of children aged 2 to 17 years presenting to the emergency department with moderate or severe asthma, defined as a Pediatric Respiratory Assessment Measure (PRAM) score of 5 to 12. The outcomes were hospital admission, relapse, and length of active treatment; they were analyzed with multivariate logistic and linear regressions adjusted for covariates and potential confounders. Among the 406 eligible children, 88% had moderate asthma; 22%, severe asthma. The median age was 4 years (interquartile range 3 to 8 years); 64% were male patients. Fifty percent of patients received systemic corticosteroids early; in 33%, it was delayed; 17% of children failed to receive any. Overall, 36% of patients were admitted to the hospital. Compared with delayed administration, early administration reduced the odds of admission by 0.4 (95% confidence interval 0.2 to 0.7) and the length of active treatment by 0.7 hours (95% confidence interval -1.3 to -0.8 hours), with no significant effect on relapse. Delayed administration was positively associated with triage priority and negatively with PRAM score. In this study of children with moderate or severe asthma, administration of systemic corticosteroids within 75 minutes of triage decreased hospital admission rate and length of active treatment, suggesting that early administration of systemic corticosteroids may allow for optimal effectiveness.

    Background & Aims It is unclear whether mortality from upper gastrointestinal hemorrhage is changing: any differences observed might result from changes in age or comorbidity of patient populations. We estimated trends in 28-day mortality in England following hospital admission for gastrointestinal hemorrhage. Methods We used a case-control study design to analyze data from all adults administered to a National Health Service hospital, for upper gastrointestinal hemorrhage, from 1999 to 2007 (n = 516,153). Cases were deaths within 28 days of admission (n = 74,992), and controls were survivors to 28 days. The 28-day mortality was derived from the linked national death register. A logistic regression model was used to adjust trends in nonvariceal and variceal hemorrhage mortality for age, sex, and comorbidities and to investigate potential interactions. Results During the study period, the unadjusted, overall, 28-day mortality following nonvariceal hemorrhage was reduced from 14.7% to 13.1% (unadjusted odds ratio, 0.87; 95% confidence interval: 0.84–0.90). The mortality following variceal hemorrhage was reduced from 24.6% to 20.9% (unadjusted odds ratio, 0.8; 95% confidence interval: 0.69–0.95). Adjustments for age and comorbidity partly accounted for the observed trends in mortality. Different mortality trends were identified for different age groups following nonvariceal hemorrhage. Conclusions The 28-day mortality in England following both nonvariceal and variceal upper gastrointestinal hemorrhage decreased from 1999 to 2007, and the reduction had been partly obscured by changes in patient age and comorbidities. Our findings indicate that the overall management of bleeding has improved within the first 4 weeks of admission. PMID:21447331

    Background and Objective: Acute gallstone pancreatitis is quite common throughout the globe. Conventionally definitive cholecystectomy has been delayed in index hospital admission. Since the last decade timing of cholecystectomy is gradually shifting towards the earlier phase of disease and currently gallstone pancreatitis is being evaluated as a further indication for laparoscopic cholecystectomy. There is also great concern regarding compliance of patients for definitive surgery due to poverty, ignorance and illiteracy in developing countries. The aim of this study was to assess the feasibility and safety of laparoscopic cholecystectomy as a definitive treatment in patients with mild and resolving gall stone pancreatitis. Methods: This was a prospective study from July 2009 to June 2012. Patients were diagnosed by clinical examination, biochemical tests, ultrasonography and contrast enhanced CT. Patients with mild form of the disease (Ranson Score ≤3) and who showed clinical improvement were offered laparoscopic cholecystectomy in index hospital admission. Those who were unfit for surgery were referred for endoscopic sphincterotomy. Common bile duct stones were excluded preoperatively. Results: A total of 38 patients were admitted with acute gallstone pancreatitis in the study period. The mean age of patients was 46.3 years with male to female ratio of 11/27. 22 (57.8%) patients were selected for laparoscopic cholecystectomy and procedure was completed successfully. Ten (26.3%) patients were referred for ERCP and endoscopic sphincterotomy and 11 (28.9%) were managed by conservative treatment and went without any definitive treatment. Mean duration of time from onset of symptoms and laparoscopic cholecystectomy was 7 days (range 4-10). Mean duration of operative time was 45 minutes and hospital stay was 7 days. There was no operative mortality. No major intra-operative or post-operative complication was recorded. two patients (9%) had minor complications

    Sudden weather changes have long been supposed to be associated with negative impacts on human health. However, relatively few studies attempted to quantify these relationships. In this study, we use large 6-hour changes of atmospheric sea level pressure as proxy for sudden weather changes, and evaluate their association with hospital admissions for cardiovascular diseases. Winter and summer seasons and positive and negative pressure changes are analyzed separately, using data for the city of Prague (population of 1.2 million) over 16-year period (1994-2009). We find that sudden pressure drops in winter are associated with significant increases in the number of hospital admissions. Increases in morbidity are not observed for pressure drops in summer, nor pressure increases in any season. Analysis of synoptic weather maps shows that the large pressure drops in winter are associated with strong zonal (westerly) flow and rapidly moving low pressure systems with centres over Northern Europe and atmospheric fronts affecting the area of Western and Central Europe. Several of the largest pressure decreases were associated with infamous winter storms (such as Lothar on December 25, 1999 and Kyrill on January 18, 2007). Analysis of links between passages of strong atmospheric fronts and hospital admissions shows that the links are much weaker if weather changes are characterized by frontal passages. Since climate models project strengthening of the zonal circulation in winter and increased frequency of winter storms, the negative effects of such weather phenomena and their possible changes in a warmer climate of the 21st century need to be better understood, particularly as their importance in inducing excess morbidity and mortality in winter may increase compared to cold spells.

    Objective Emergency department (ED) crowding is linked with poor quality of care and worse outcomes, including higher mortality. With the growing emphasis on hospital performance measures, there is additional concern whether inadequate care during crowded periods increases a patient’s likelihood of subsequent inpatient admission. We sought to determine if ED crowding during the index visit was associated with these “bounceback” admissions. Methods We used comprehensive, non-public, statewide ED and inpatient discharge data from the California Office of Statewide Health Planning and Development from 2007 to identify index outpatient ED visits and bounceback admissions within seven days. We further used ambulance diversion data collected from California local emergency medical services agencies to identify crowded days using intra-hospital daily diversion hour quartiles. Using a hierarchical logistic regression model, we then determined if patients visiting on crowded days were more likely to have a subsequent bounceback admission. Results We analyzed 3,368,527 index visits across 202 hospitals, of which 596,471 (17.7%) observations were on crowded days. We found no association between ED crowding and bounceback admissions. This lack of relationship persisted in both a discrete (high/low) model (OR 1.01, 95% CI 0.99, 1.02) and a secondary model using ambulance diversion hours as a continuous predictor (OR 1.00, 95% CI 1.00, 1.00). Conclusions Crowding as measured by ambulance diversion does not have an association with hospitalization within 7 days of an ED visit discharge. Therefore, bounceback admission may be a poor measure of delayed or worsened quality of care due to crowding. PMID:24036997

    The aim of our study is to analyse hospital readmissions due to asthma, as well as the factors associated with their increase. We carried out a retrospective study including all admissions of patients over 18 years old due to exacerbation of asthma occurring in our hospital between the years 2000 and 2010. The data were gathered by two members of the research team, by reviewing the clinical records. The first hospital admission of each patient was included for this study. An early readmission (ER) was defined as that which occurred in the following 15 days after hospital discharge and late readmission (LR) to that occurring from 16 days after discharge. This study included 2166 hospital admissions and 1316 patients, with a mean age of 62.6 years. Of the 1316 patients analysed, 36 (2.7%) had one ER and 313 (23.8%) one LR. The only factor independently associated with a higher probability of an ER was poor lung function. A higher probability of LR was associated with a greater severity of the asthma (OR: 17.8, for severe asthma versus intermittent asthma), to have had any hospital admission in the previous year (OR: 3.5) and the use of a combination of ICS-LABA as maintenance treatment. About 25% of the patients in our area admitted to hospital due to asthma exacerbation had repeat episodes of hospitalisation.

    Exposure to secondhand smoke is associated with an increased risk of acute myocardial infarction (AMI). The positive impact of a smoking ban on AMI hospitalization rates has been demonstrated both inside and outside Europe. A national smoking ban (SB) was implemented in Denmark on 15 August 2007. To evaluate the impact of the Danish SB on hospital admissions for AMI. Poisson regression models were used to analyse changes over time in AMI-admissions in Denmark. We investigated a seven year period: five years before and two years after implementation of the SB. We accounted for the variation in the population size and for seasonal trends. Potential confounders included were: gender, age and the incidence of type 2 diabetes (T2D). A significant reduction in the number of AMI-admissions was found in the last three years of the study period after adjusting for the potential confounders. The significant reductions were found one year before the SB (relative rate (RR) = 0.86, 95% confidence interval (CI) 0.79-0.94), one year after the SB (RR = 0.77, 95% CI 0.71-0.85) and two years after the SB (RR = 0.77, 95% CI 0.70-0.84). A significant reduction in the number of AMI-admissions was found already one year before the SB after adjustment for the incidence of T2D. The results differ from most results found in similar studies throughout the world and may be explained by the incremental enactment of SBs in Denmark and the implementation of a nation-wide ban on industrially produced trans-fatty acids in food in 2004.

    Background Availability of alcohol is a major policy issue for governments, and one of the availability factors is the density of alcohol outlets within geographic areas. Objective The aim of this study is to investigate the association between alcohol outlet density and hospital admissions for alcohol-related conditions in a national (English) small area level ecological study. Methods This project will employ ecological correlation and cross-sectional time series study designs to examine spatial and temporal relationships between alcohol outlet density and hospital admissions. Census units to be used in the analysis will include all Lower and Middle Super-Output Areas (LSOAs and MSOAs) in England (53 million total population; 32,482 LSOAs and 6781 MSOAs). LSOAs (approximately 1500 people per LSOA) will support investigation at a fine spatial resolution. Spatio-temporal associations will be investigated using MSOAs (approximately 7500 people per MSOA). The project will use comprehensive coverage data on alcohol outlets in England (from 2003, 2007, 2010, and 2013) from a commercial source, which has estimated that the database includes 98% of all alcohol outlets in England. Alcohol outlets may be classified into two broad groups: on-trade outlets, comprising outlets from which alcohol can be purchased and consumed on the premises (eg, pubs); and off-trade outlets, in which alcohol can be purchased but not consumed on the premises (eg, off-licenses). In the 2010 dataset, there are 132,989 on-trade and 51,975 off-trade outlets. The longitudinal data series will allow us to examine associations between changes in outlet density and changes in hospital admission rates. The project will use anonymized data on alcohol-related hospital admissions in England from 2003 to 2013 and investigate associations with acute (eg, admissions for injuries) and chronic (eg, admissions for alcoholic liver disease) harms. The investigation will include the examination of conditions that

    we evaluated the association of daily pollutants' concentrations with daily hospital admissions for respiratory causes in children residents in Pisa during 1998-2002. We compared the results obtained with two methods of statistical analyses. A total of 657 children under ten years and admitted to local hospitals for respiratory diseases (ICD 9: 460-469, 480- 519) were included in the study. both time-series and case-crossover analysis were applied, controlling for temperature, holidays, influenza epidemics,rain and relative humidity. Pollutants' effects are expressed as percentage increase (and 95% CI) of hospital admissions for an increase of 10 μg/m³ of pollutants (1 mg/m³ for CO). with both analyses, children's hospital admissions for respiratory conditions were significantly associated to increasing daily levels of PM10 and CO at different time lags, while no association was found for NO₂ and O₃. In the case-crossover analysis, for a daily increase of 10 μg/m³ in PM10, a significant increment of 8.5% (CI 95% 0.02; 17.6) in children respiratory admissions was observed at lag 0-3. Results were stronger for males and during the warm season. A 1 mg/m³ increment in daily CO levels was associated with an increase of respiratory admissions at lag 0 (20.2%, CI 95% 5.3; 37.2) and at all cumulative lags: the maximum value was observed at lag 0-3 (32.6%, CI 95%8.3; 62.2). Time series analyses provides similar results, although the estimates were lower than with the other method, in terms of percentage increment and length of confidence intervals. this study indicates adverse effects of air pollution on respiratory health of children living in urban environment. The results of both analyses were consistent.

    Objectives Evaluate the validity of the International Classification of Diseases, 10th revision (ICD-10) code for hyperkalaemia (E87.5) in two settings: at presentation to an emergency department and at hospital admission. Design Population-based validation study. Setting 12 hospitals in Southwestern Ontario, Canada, from 2003 to 2010. Participants Elderly patients with serum potassium values at presentation to an emergency department (n=64 579) and at hospital admission (n=64 497). Primary outcome Sensitivity, specificity, positive-predictive value and negative-predictive value. Serum potassium values in patients with and without a hyperkalaemia code (code positive and code negative, respectively). Results The sensitivity of the best-performing ICD-10 coding algorithm for hyperkalaemia (defined by serum potassium >5.5 mmol/l) was 14.1% (95% CI 12.5% to 15.9%) at presentation to an emergency department and 14.6% (95% CI 13.3% to 16.1%) at hospital admission. Both specificities were greater than 99%. In the two settings, the positive-predictive values were 83.2% (95% CI 78.4% to 87.1%) and 62.0% (95% CI 57.9% to 66.0%), while the negative-predictive values were 97.8% (95% CI 97.6% to 97.9%) and 96.9% (95% CI 96.8% to 97.1%). In patients who were code positive for hyperkalaemia, median (IQR) serum potassium values were 6.1 (5.7 to 6.8) mmol/l at presentation to an emergency department and 6.0 (5.1 to 6.7) mmol/l at hospital admission. For code-negative patients median (IQR) serum potassium values were 4.0 (3.7 to 4.4) mmol/l and 4.1 (3.8 to 4.5) mmol/l in each of the two settings, respectively. Conclusions Patients with hospital encounters who were ICD-10 E87.5 hyperkalaemia code positive and negative had distinct higher and lower serum potassium values, respectively. However, due to very low sensitivity, the incidence of hyperkalaemia is underestimated. PMID:23274674

    Expiratory flow limitation (EFL) is seen in some patients presenting with a COPD exacerbation; however, it is unclear how EFL relates to the clinical features of the exacerbation. We hypothesized that EFL when present contributes to symptoms and duration of recovery during a COPD exacerbation. Our aim was to compare changes in EFL with symptoms in subjects with and without flow-limited breathing admitted for a COPD exacerbation. A total of 29 subjects with COPD were recruited within 48 hours of admission to West China Hospital for an acute exacerbation. Daily measurements of post-bronchodilator spirometry, resistance, and reactance using the forced oscillation technique and symptom (Borg) scores until discharge were made. Flow-limited breathing was defined as the difference between inspiratory and expiratory respiratory system reactance (EFL index) greater than 2.8 cmH2O·s·L(-1). The physiological predictors of symptoms during recovery were determined by mixed-effect analysis. Nine subjects (31%) had flow-limited breathing on admission despite similar spirometry compared to subjects without flow-limited breathing. Spirometry and resistance measures did not change between enrolment and discharge. EFL index values improved in subjects with flow-limited breathing on admission, with resolution in four patients. In subjects with flow-limited breathing on admission, symptoms were related to inspiratory resistance and EFL index values. In subjects without flow-limited breathing, symptoms related to forced expiratory volume in 1 second/forced vital capacity. In the whole cohort, EFL index values at admission was related to duration of stay (Rs=0.4, P=0.03). The presence of flow-limited breathing as well as abnormal respiratory system mechanics contribute independently to symptoms during COPD exacerbations.

    To examine links between clinical and other characteristics of people with Alzheimer's disease living in the community, likelihood of care home or hospital admission, and associated costs. Observational data extracted from clinical records using natural language processing and Hospital Episode Statistics. Statistical analyses examined effects of cognition, physical health, mental health, sociodemographic factors and living circumstances on risk of admission to care home or hospital over 6 months and associated costs, adjusting for repeated observations. Catchment area for South London and Maudsley National Health Service Foundation Trust, provider for 1.2 million people in Southeast London. Every individual with diagnosis of Alzheimer's disease seen and treated by mental health services in the catchment area, with at least one rating of cognition, not resident in care home at time of assessment (n=3075). Usual treatment. Risk of admission to, and days spent in three settings during 6-month period following routine clinical assessment: care home, mental health inpatient care and general hospital inpatient care. Predictors of probability of care home or hospital admission and/or associated costs over 6 months include cognition, functional problems, agitation, depression, physical illness, previous hospitalisations, age, gender, ethnicity, living alone and having a partner. Patterns of association differed considerably by destination. Most people with dementia prefer to remain in their own homes, and funding bodies see this as cheaper than institutionalisation. Better treatment in the community that reduces health and social care needs of Alzheimer's patients would reduce admission rates. Living alone, poor living circumstances and functional problems all raise admission rates, and so major cuts in social care budgets increase the risk of high-cost admissions which older people do not want. Routinely collected data can be used to reveal local patterns of admission

    Older people living in Residential Aged Care Facilities (RACF) are a vulnerable, frail and complex population. They are more likely than people who reside in the community to become acutely unwell, present to the Emergency Department (ED) and require admission to hospital. For many, hospitalisation carries with it risks. Importantly, evidence suggests that some admissions are avoidable. A new collaborative model of care, the Aged Care Emergency Service (ACE), was developed to provide clinical support to nurses in the RACFs, allowing residents to be managed in place and avoid transfer to the ED. This paper examines the effects of the ACE service on RACF residents' transfer to hospital using a controlled pre-post design. Four intervention RACFs were matched with eight control RACFs based on number of total beds, dementia specific beds, and ratio of high to low care beds in Newcastle, Australia, between March and November 2011. The intervention consisted of a clinical care manual to support care along with a nurse led telephone triage line, education, establishing goals of care prior to ED transfer, case management when in the ED, along with the development of collaborative relationships between stakeholders. Outcomes included ED presentations, length of stay, hospital admission and 28-day readmission pre- and post-intervention. Generalised estimating equations were used to estimate mean differences in outcomes between intervention and controls RACFs, pre- and post-intervention means, and their interaction, accounting for repeated measures and adjusting for matching factors. Residents had a mean age of 86 years. ED presentations ranged between 16 and 211 visits/100 RACF beds/year across all RACFs. There was no overall reduction in ED presentations (OR = 1.17, p = 0.56) with the ACE intervention. However, when compared to the controls, the intervention group reduced their ED length of stay by 45 min (p = 0.0575), and was 40 % less likely to be admitted

    Telephone-based disease management (DM) programs can improve health outcomes and provide a positive return on investment to funders. However, there is scant evidence about how to use hospital admission episode data to identify patients who are most likely to participate in a DM program. The objective of this study was to use hospital admission episode data held by health insurers to determine those factors that predict members with chronic disease joining and remaining in a DM program for at least 6 months. A multivariable logistic regression model was constructed to determine predictors of participating in a DM program for an insured population who had been admitted to hospital for congestive heart failure, coronary artery disease, or chronic obstructive pulmonary disease. The outcome variable was binary: did the member both opt into the DM program and remain in the program for at least 6 months? The study population included 9874 private health fund members. Time from a related hospital admission was a significant predictor, with those offered the program within 3 to 6 months being 71% more likely (95% confidence interval [CI]: 33%, 113%) to participate. The length of time from offer to commencement also was a significant predictor, with those commencing within 3 to 4 months being 75% (95% CI: 44%, 112%) as likely to remain in the program. It is possible to predict which individuals are most likely to participate in a telephone-based DM program using hospital admission episode data. Once individuals are identified, timely commencement of a DM program is an important predictor of success.

    This study investigated cognitive functioning among older adults with physical debility not attributable to an acute injury or neurological condition who were receiving subacute inpatient physical rehabilitation. A cohort investigation with assessments at admission and discharge. Three geriatric rehabilitation hospital wards. Consecutive rehabilitation admissions (n = 814) following acute hospitalization (study criteria excluded orthopaedic, neurological, or amputation admissions). Usual rehabilitation care. The Functional Independence Measure (FIM) Cognitive and Motor items. A total of 704 (86.5%) participants (mean age = 76.5 years) completed both assessments. Significant improvement in FIM Cognitive items (Z-score range 3.93-8.74, all P < 0.001) and FIM Cognitive total score (Z-score = 9.12, P < 0.001) occurred, in addition to improvement in FIM Motor performance. A moderate positive correlation existed between change in Motor and Cognitive scores (Spearman's rho = 0.41). Generalized linear modelling indicated that better cognition at admission (coefficient = 0.398, P < 0.001) and younger age (coefficient = -0.280, P < 0.001) were predictive of improvement in Motor performance. Younger age (coefficient = -0.049, P < 0.001) was predictive of improvement in FIM Cognitive score. Improvement in cognitive functioning was observed in addition to motor function improvement among this population. Causal links cannot be drawn without further research.

    IMPORTANCE Heat exposure is known to have a complex set of physiological effects on multiple organ systems, but current understanding of the health effects is mostly based on studies investigating a small number of prespecified health outcomes such as cardiovascular and respiratory diseases. OBJECTIVES To identify possible causes of hospital admissions during extreme heat events and to estimate their risks using historical data. DESIGN, SETTING, AND POPULATION Matched analysis of time series data describing daily hospital admissions of Medicare enrollees (23.7 million fee-for-service beneficiaries [aged ≥65 years] per year; 85% of all Medicare enrollees) for the period 1999 to 2010 in 1943 counties in the United States with at least 5 summers of near-complete (>95%) daily temperature data. EXPOSURES Heat wave periods, defined as 2 or more consecutive days with temperatures exceeding the 99th percentile of county-specific daily temperatures, matched to non–heat wave periods by county and week. MAIN OUTCOMES AND MEASURES Daily cause-specific hospitalization rates by principal discharge diagnosis codes, grouped into 283 disease categories using a validated approach. RESULTS Risks of hospitalization for fluid and electrolyte disorders, renal failure, urinary tract infection, septicemia, and heat stroke were statistically significantly higher on heat wave days relative to matched non–heat wave days, but risk of hospitalization for congestive heart failure was lower (P < .05). Relative risks for these disease groups were 1.18 (95% CI, 1.12–1.25) for fluid and electrolyte disorders, 1.14 (95% CI, 1.06–1.23) for renal failure, 1.10 (95% CI, 1.04–1.16) for urinary tract infections, 1.06 (95% CI, 1.00–1.11) for septicemia, and 2.54 (95% CI, 2.14–3.01) for heat stroke. Absolute risk differences were 0.34 (95% CI, 0.22–0.46) excess admissions per 100 000 individuals at risk for fluid and electrolyte disorders, 0.25 (95% CI, 0.12–0.39) for renal failure, 0

    Two doses of measles vaccine (MV) might reduce the nonmeasles mortality rate more than 1 dose of MV does. The effect of 2 versus 1 dose on morbidity has not been examined. Within a randomized trial of the effect of 2 doses versus 1 dose of MV on mortality in Guinea-Bissau, we investigated the effect on hospital admissions. Children were randomly assigned 1:2 to receive MV at 4.5 and 9 months of age or the currently recommended dose at 9 months. We compared hospital admission rates among children between 9 and 18 months of age in a Cox regression model with age as the underlying time scale. Half of the children had received neonatal vitamin A supplementation (NVAS) in another trial. The beneficial effect of MV at 4.5 and 9 months on mortality was limited to children who had not received NVAS; therefore, we investigated the interaction of MV with NVAS on admission rates. Among 5626 children (2 doses of MV, 1960 children; 1 dose of MV, 3666), we identified 311 hospital admissions of children between 9 and 18 months of age. Overall, compared to 1 dose of MV, 2 doses reduced the risk of hospital admission for children who had not received NVAS (hazard ratio [HR], 0.66 [95% confidence interval (CI), 0.47-0.93]), but we found no effect among NVAS recipients (HR, 1.16 [95% CI, 0.82-1.63]) (P = .02 for interaction). The benefit of 2 doses of MV was limited to children who had not received NVAS. NVAS is not generally recommended; hence, an early 2-dose measles vaccination policy might reduce hospital admissions more than the current policy of providing the first MV at 9 months of age.

    Objectives: This paper reports on the findings of a population-based study to evaluate the relationship between atmospheric fine particulate matter (PM2.5) levels and hospital admissions for chronic obstructive pulmonary disease (COPD) in southwestern Taiwan over a three-year period, 2008–2010. Methods: Data on hospital admissions for COPD and PM2.5 levels were obtained from the National Health Insurance Research database (NHIRD) and the Environmental Protection Administration from 2008 to 2010, respectively. The lag structure of relative risks (RRs) of hospital admissions for COPD was estimated using a Poisson regression model. Results: During the study period, the overall average hospitalization rate of COPD and mean 24-h average level of PM2.5 was 0.18% and 39.37 μg/m3, respectively. There were seasonal variations in PM2.5 concentrations in southwestern Taiwan, with higher PM2.5 concentrations in both spring (average: 48.54 μg/m3) and winter (49.96 μg/m3) than in summer (25.89 μg/m3) and autumn (33.37 μg/m3). Increased COPD admissions were significantly associated with PM2.5 in both spring (February–April) and winter (October–January), with the relative risks (RRs) for every 10 μg/m3 increase in PM2.5 being 1.25 (95% CI = 1.22–1.27) and 1.24 (95% CI = 1.23–1.26), respectively, at a lag zero days (i.e., no lag days). Lag effects on COPD admissions were observed for PM2.5, with the elevated RRs beginning at lag zero days and larger RRs estimates tending to occur at longer lags (up to six days, i.e., lag 0–5 days). Conclusions: In general, findings reveal an association between atmospheric fine particulate matter (PM2.5) and hospital admissions for COPD in southwestern Taiwan, especially during both spring and winter seasons.

    Patient-controlled admissions (PCAs) enable mental health patients by means of a contract to initiate an admission at a mental health hospital unit without using traditional admission procedures. This study was part of a 3-year Danish multicenter project, and we explored how mental health professionals experienced and managed the implementation of a PCA program. The methodology was grounded theory and the sample included 26 participants. We performed a constant comparative analysis to explore the concerns, attitudes, and strategies of mental health professionals. We developed a model of how the mental health professionals strived to integrate PCA into clinical practice. The process was motivated by the idea of establishing a partnership with patients and involved two interrelated strategies to manage (a) the patient-related duties and (b) the admission contracts. The professionals moved from a phase of professional discomfort to a phase of professional awareness, and ended up with professional comprehension.

    A number of studies have established the effects of space weather on the human cardio-vascular system. We investigated whether geomagnetic storms (GS), solar proton events (SPEs), and X-class solar flare affect the risk of emergency hospitalization for acute myocardial infarction (MI) separately during declining (2004-2006) and rising (2010-2012) phases of solar activity. The data on hospital admissions for MI were obtained from the computer database of Lithuanian University of Health sciences from January 1, 2004 to December 31, 2012. We evaluated the associations between space weather conditions and the daily number of emergency admissions for MI by Poisson regression, controlling for seasonal variation and weekdays. During 2004-2006, an increase in the risk of hospital admission for MI was observed on days of the daily mean proton >10 MeV flux >100 pfu (by 63%, p<0.001) and on days of GS concomitant with SPE, 1-2 days following these events, and on days of SPE occurring 1-2 days before GS concomitant with SPE (by 26%, p=0.019). During 2010-2012, an increase in the risk of hospital admission for MI was observed on days of the daily mean proton >10 MeV flux >100 pfu (by 52%, p=0.015) and on days of GS and 1-2 days after GS (by 17%, p=0.024). These findings suggest that the impact of hazardous space weather conditions on human health depends of the strength of space storm during the investigated period.

    To assess the impact of performance status (PS) impairment 1 week before hospital admission on the outcomes in patients admitted to intensive care units (ICU). Retrospective cohort study in 59,693 patients (medical admissions, 67 %) admitted to 78 ICUs during 2013. We classified PS impairment according to the Eastern Cooperative Oncology Group (ECOG) scale in absent/minor (PS = 0-1), moderate (PS = 2) or severe (PS = 3-4). We used univariate and multivariate logistic regression analyses to investigate the association between PS impairment and hospital mortality. PS impairment was moderate in 17.3 % and severe in 6.9 % of patients. The hospital mortality was 14.4 %. Overall, the worse the PS, the higher the ICU and hospital mortality and length of stay. In addition, patients with worse PS were less frequently discharged home. PS impairment was associated with worse outcomes in all SAPS 3, Charlson Comorbidity Index and age quartiles as well as according to the admission type. Adjusting for other relevant clinical characteristics, PS impairment was associated with higher hospital mortality (odds-ratio (OR) = 1.96 (95 % CI 1.63-2.35), for moderate and OR = 4.22 (3.32-5.35), for severe impairment). The effects of PS on the outcome were particularly relevant in the medium range of severity-of-illness. These results were consistent in the subgroup analyses. However, adding PS impairment to the SAPS 3 score improved only slightly its discriminative capability. PS impairment was associated with worse outcomes independently of other markers of chronic health status, particularly for patients in the medium range of severity of illness.

    Objective: Infections are a major cause of morbidity and mortality in systemic lupus erythematosus. Clinical outcomes of systemic lupus erythematosus patients hospitalized due to infections vary among different ethnic populations. Thus, we determined the outcomes and associated factors in a group of Hispanics from Puerto Rico with systemic lupus erythematosus admitted due to severe infections. Methods: Records of systemic lupus erythematosus patients admitted to the Adult University Hospital, San Juan, Puerto Rico, from January 2006 to December 2014 were examined. Demographic parameters, lupus manifestations, comorbidities, pharmacologic treatments, inpatient complications, length of stay, readmissions, and mortality were determined. Patients with and without infections were compared using bivariate and multivariate analyses. Results: A total of 204 admissions corresponding to 129 systemic lupus erythematosus patients were studied. The mean (standard deviation) age was 34.7 (11.6) years; 90% were women. The main causes for admission were lupus flare (45.1%), infection (44.0%), and initial presentation of systemic lupus erythematosus (6.4%). The most common infections were complicated urinary tract infections (47.0%) and soft tissue infections (42.0%). In the multivariate analysis, patients admitted with infections were more likely to have diabetes mellitus (odds ratio: 4.20, 95% confidence interval: 1.23–14.41), exposure to aspirin prior to hospitalization (odds ratio: 4.04, 95% confidence interval: 1.03–15.80), and higher mortality (odds ratio: 6.00, 95% confidence interval: 1.01–35.68) than those without infection. Conclusion: In this population of systemic lupus erythematosus patients, 44% of hospitalizations were due to severe infections. Patients with infections were more likely to have diabetes mellitus and higher mortality. Preventive and control measures of infection could be crucial to improve survival in these patients.

    Due to a global warming-related increase in heatwaves, it is important to obtain detailed understanding of the relationship between heat and health. We assessed the relationship between heat and urgent emergency room admissions in the Netherlands. We collected daily maximum temperature and relative humidity data over the period 2002-2007. Daily urgent emergency room admissions were divided by sex, age group and disease category. We used distributed lag non-linear Poisson models, estimating temperature-admission associations. We estimated the relative risk (RR) for urgent hospital admissions for a range of temperatures compared to a baseline temperature of 21 °C. In addition, we compared the impact of three different temperature scenarios on admissions using the RR. There is a positive relationship between increasing temperatures above 21 °C and the RR for urgent emergency room admissions for the disease categories 'Potential heat-related diseases' and 'Respiratory diseases'. This relationship is strongest in the 85+ group. The RRs are strongest for lag 0. For admissions for 'circulatory diseases', there is only a small significant increase of RRs within the 85+ age group for moderate heat, but not for extreme heat. The RRs for a one-day event with extreme heat are comparable to the RRs for multiple-day events with moderate heat. Hospitals should adjust the capacity of their emergency departments on warm days, and the days immediately thereafter. The elderly in particular should be targeted through prevention programmes to reduce harmful effects of heat. The fact that this increase in admissions already occurs in temperatures above 21 °C is different from previous findings in warmer countries. Given the similar impact of three consecutive days of moderate heat and one day of extreme heat on admissions, criteria for activation of national heatwave plans need adjustments based on different temperature scenarios.

    Seniors comprise 14% to 21% of all emergency department (ED) visits, yet are disproportionately larger users of ED and inpatient resources. ED care coordinators (EDCCs) target seniors at risk for functional decline and connect them to home care and other community services in hopes of avoiding hospitalization. The goal of this study was to measure the association between the presence of EDCCs and admission rates for seniors aged ≥ 65. Secondary outcomes included length of stay, recidivism at 30 days, and revisit resulting in admission at 30 days. This was a matched pairs study using administrative data from eight EDs in six Alberta cities. Four of these hospitals were intervention sites, in which patients were seen by an EDCC, while the other four sites had no EDCC presence. All seniors aged ≥ 65 with a discharge diagnosis of fall or musculoskeletal pathology were included. Cases were matched by CTAS category, age, gender, mode of arrival, and home living environment. McNemar's test for matched pairs was used to compare admission and recidivism rates at EDCC and non-EDCC hospitals. A paired t-test was used to compare length of stay between groups. There were no statistically significant differences for baseline admission rate, revisit rate at 30 days, and readmission rate at 30 days between EDCC and non-EDCC patients. This study showed no reduction in senior patients' admission rates, recidivism at 30 days, or hospital length of stay when comparing seniors seen by an EDCC with those not seen by an EDCC.

    Children with complex chronic conditions (CCC) have greater health care needs and use rates than children in general. Elevated health care use includes more frequent hospital admissions, longer hospital stays, and greater health care expenses. Prior studies have examined population characteristics associated with increased hospital admissions, emergency department (ED) use, and general healthcare use, yet few studies have investigated these events from the parents' or health care providers' point of view. The purpose of this study was to explore parents/caregivers' and health care providers' perceptions of the factors placing infants and young children with CCC at risk for or protecting them against hospital admissions and ED visits. Parents or primary caregivers participated in interviews, and health care providers in pediatric acute care, pediatric primary care, and emergency care participated in focus groups. Interview and focus group data were analyzed using directed content analysis and an ecological risk and protective factors model. The analysis revealed that parents/caregivers and health care providers described risk factors and protective factors on multiple ecological levels surrounding the child with CCC. This article presents these findings, which add to current knowledge of factors influencing hospital admissions and ED visits and may be used to inform interventions addressing high health care utilization in this population. This article concludes with the implications of the findings for future research and nursing practice. PMID:24423943

    BACKGROUND: Malnutrition among hospitalized children is known to negatively influence their response to therapy and to prolong their admission. It also has short- and long-term consequences for growth, development and well-being. It is commonly regarded as a condition affecting children in low-income countries; however, malnutrition has been found to be variably prevalent among hospitalized children in higher-income countries. At the time the present study was conducted, it had been >30 years since the nutritional status of Canadian hospitalized children was last published. OBJECTIVES: To determine and communicate the prevalence of malnutrition among children in a Canadian tertiary-care paediatric hospital at the time of their admission. METHODS: In the present cross-sectional study, anthropometric measures were obtained from 322 children admitted to The Hospital for Sick Children in Toronto, Ontario. Nutritional indexes (BMI for age, weight for age, weight for length/height and length/height for age) were generated from anthropometric measures using the WHO igrowup software, and summarized according to WHO definitions. RESULTS: The overall prevalence of malnutrition using BMI for age was 39.6% (95% CI 33% to 46%), of which 8.8% and 30.8% of participants were under- and overnourished, respectively. Furthermore, 6.9% (95% CI 3% to 13%) were determined to be acutely malnourished (weight for length/height <−2 SD) and 13.4% (95% CI 10% to 18%) chronically malnourished (length/height for age <−2 SD). CONCLUSION: The high prevalence of overall malnutrition observed among study participants suggests that initial screening using simple anthropometric measures should be conducted on hospital admission so that patients can receive appropriate nutrition-specific care.

    In times of financial restrictions and reform impediments, health services need to invest in resources that provide value for money and reduce hospital admissions. Improving disease management in the community is a primary target for those trying to reduce costs. The second most common cause of emergency admissions to hospital is chronic obstructive pulmonary disease and it has been suggested that more effective treatments and better management of the condition would likely result in an estimated 5% fewer admissions to hospital, saving around pound 15.5m each year. This article discusses how savings could be made by improving care provided in the community.

    Tetanus accounts for high morbidity and case fatality rates in developing countries. This study therefore aimed to identify reasons for the persistence of this disease. Paediatric admissions at Ladoke Akintola University Teaching Hospital between 1 January 2006 and 31 December 2008 diagnosed with tetanus were studied. Data was analyzed with SPSS 18 and statistical significance was set at p < 0.05. Of the total 1,681 paediatric admissions, 30 (1.8%) had tetanus. Of the 878 neonatal admissions, 8 (0.9%) had tetanus, while 22 (2.7%) of the total 803 post-neonatal admissions had tetanus. Neonatal tetanus admissions were significantly higher in 2006 compared to 2007 and 2008 (7 [2.3%] versus 1 [0.2%] [χ²= 7.50, P=0.01]). Of the eight mothers whose neonates had tetanus, seven did not receive tetanus toxoids in pregnancy and five (62.5%) were secondary school dropouts. Post-neonatal tetanus cases admitted in the years 2006, 2007, and 2008 were 4, 12, and 6 children respectively. Most of these 22 children did not receive tetanus toxoid immunization in their first year of life. None of the 22 children received booster doses of tetanus toxoids after their first years of life. Mothers at risk of their babies having tetanus, such as secondary school dropouts, must be identified antenatally and vaccinated with tetanus toxiod. Their babies should also receive good care post-delivery. Completion of routine tetanus toxoid schedule in the first year and booster doses in the post-neonatal age should be ensured.

    Paediatric abusive head trauma (AHT) is a leading cause of fatal child maltreatment among young children. Current prevention efforts have not been consistently effective. Policies such as paid parental leave could potentially prevent AHT, given its impacts on risk factors for child maltreatment. To explore associations between California's 2004 paid family leave (PFL) policy and hospital admissions for AHT, we used difference-in-difference analyses of 1995-2011 US state-level data before and after the policy in California and seven comparison states. Compared with seven states with no PFL policies, California's 2004 PFL showed a significant decrease in AHT admissions in both <1 and <2-year-olds. Analyses using additional data years and comparators could yield different results. Published by the BMJ Publishing Group Limited.

    In developing countries up to 77% of children with cancer have been shown to be malnourished on admission. High rates of malnutrition occur due to factors such as poverty and advanced disease. Weight can be an inaccurate parameter for nutritional assessment of children with solid tumours as it is influenced by tumour mass. This study aimed to assess the prevalence of malnutrition amongst children with Wilms tumour (WT), the level of nutritional support received on admission and the influence of nutritional status on outcome. Seventy-six children diagnosed with WT and admitted to Inkosi Albert Luthuli Central Hospital between 2004 and 2012 were studied prospectively. Nutritional assessment was conducted using weight, height, mid-upper arm circumference (MUAC) and triceps skinfold thickness (TSFT) prior to initiating treatment. Outcome was determined 2 years after admission. Time until commencement of nutritional resuscitation and nature, thereof, were recorded. Stunting and wasting was evident in 12% and 15% of patients, respectively. The prevalence of malnutrition was 66% when MUAC, TSFT and albumin were used. Malnutrition was not a predictor of poor outcome and did not predict advanced disease. The majority of patients (84%) received nutritional resuscitation within 2 weeks of admission. When classifying nutritional status in children with WT, the utilisation of weight and height in isolation can lead to an underestimation of the prevalence of malnutrition. Nutritional assessment of children with WT should also include MUAC and TSFT. Early aggressive nutritional resuscitation is recommended. © 2016 Wiley Periodicals, Inc.

    OBJECTIVE To evaluate the physical inactivity-related inpatient costs of chronic non-communicable diseases. METHODS This study used data from 2013, from Brazilian Unified Health System, regarding inpatient numbers and costs due to malignant colon and breast neoplasms, cerebrovascular diseases, ischemic heart diseases, hypertension, diabetes, and osteoporosis. In order to calculate the share physical inactivity represents in that, the physical inactivity-related risks, which apply to each disease, were considered, and physical inactivity prevalence during leisure activities was obtained from Pesquisa Nacional por Amostra de Domicílio (Brazil’s National Household Sample Survey). The analysis was stratified by genders and residing country regions of subjects who were 40 years or older. The physical inactivity-related hospitalization cost regarding each cause was multiplied by the respective share it regarded to. RESULTS In 2013, 974,641 patients were admitted due to seven different causes in Brazil, which represented a high cost. South region was found to have the highest patient admission rate in most studied causes. The highest prevalences for physical inactivity were observed in North and Northeast regions. The highest inactivity-related share in men was found for osteoporosis in all regions (≈ 35.0%), whereas diabetes was found to have a higher share regarding inactivity in women (33.0% to 37.0% variation in the regions). Ischemic heart diseases accounted for the highest total costs that could be linked to physical inactivity in all regions and for both genders, being followed by cerebrovascular diseases. Approximately 15.0% of inpatient costs from Brazilian Unified Health System were connected to physical inactivity. CONCLUSIONS Physical inactivity significantly impacts the number of patient admissions due to the evaluated causes and through their resulting costs, with different genders and country regions representing different shares.

    Objective This study compared the sociodemographic and clinical characteristics and pathways to admission for women admitted to women’s crisis houses and to psychiatric hospitals. A women’s crisis house is a residential mental health crisis facility for women who would otherwise be considered for voluntary hospital admission. Methods A survey of all 388 female admissions to women’s crisis houses and psychiatric hospitals in four boroughs of London during a 12-week period in 2006 was conducted with questionnaires administered to key workers involved in the admissions. Results Pathways to admission were significantly less complex for women admitted to the crisis houses (fewer preadmission contacts with police, emergency departments, and other services). Women admitted to psychiatric wards were more likely to require supervision or observation. A multivariate analysis of data for the 245 voluntary admissions indicated that women admitted to women’s crisis houses were significantly less likely to have a care coordinator (odds ratio [OR]=.528) or to have gone to an accident and emergency department (OR=.214) before admission. No other differences were found between the two groups. Conclusions Pathways to admission were somewhat different for women admitted to women’s crisis houses, but few clinical or sociodemographic differences were found between the two groups. Women’s crisis houses may be a viable alternative to traditional wards for voluntary patients not needing intensive supervision and observation. Research should examine whether women’s crisis houses are as effective as traditional inpatient services in treating women with acute psychiatric problems. PMID:19033172

    Inpatient hospital stays for patients with epilepsy represent a significant burden on patients and society. Identifying factors that contribute to such costs aides in developing effective strategies to address this burden. July admissions have been associated with higher rates of complications and worse outcomes, attributed to the presence of new physicians. This study aims to evaluate whether epilepsy patients admitted in July have higher preventable complication rates and mortality than during the rest of the year. Data was derived from the Nationwide Inpatient Sample (NIS) for epilepsy admissions for the years 2000-2010. Multivariable analyses assessed the effect of July against non-July admission on "hospital acquired complications" (HAC), which are complications identified as owing to preventable causes and mortality. Additionally, the total adjusted charges and prolonged length of stay (pLOS) for July admissions were compared to the 50th percentile. A total of 12,997,181 admissions for epilepsy were identified with 993,619 (8%) occurring in July, 10,810,900 (83%) were non-July months, and 1,192,662 (9%) were missing data. Patients admitted in July showed an increased association for HAC events (RR=1.02, [1.01,1.03], p<0.01), but a decrease in mortality (RR=0.96, [0.95,0.97], p<0.01). There was no difference in rates of higher total adjusted charges for July admissions (RR=1.00, [1.00,1.00], p<0.01) and a decrease in rates of pLOS (RR=0.99, [0.98,0.99], p<0.01). In the epilepsy population, although July admissions were associated with a slight increase in HAC events, there was a non-significant or decreased rate of mortality, LOS, and total charge. Our results suggest that although complications were increased in July, possibly due to new staff, supervision is sufficient to prevent significant burden on patients and hospitals.

    Over 6 months, all admissions to three geriatric wards were studied to define an admission plasma glucose level (APG) that identified previously undiagnosed diabetes mellitus. Subjects with APG> or =7.0 mmol l(-1) had a modified oral glucose tolerance test (OGTT) when well before discharge if their dose of steroid and/or thiazide was constant, and they were neither terminally ill nor dead; excluded were 1 subject on reducing steroid doses, and 9 moribund admissions without APG. If the first 2 h OGTT result was > or =11.1 mmol l(-1), a second OGTT was performed 6 weeks later to fulfil 1985 WHO criteria. Subjects with APG<7.0 mmol l(-1) did not have OGTT. Seventy had a previous diagnosis of diabetes; scrutiny of records and OGTT refuted the diagnosis in 5, who were excluded from further analysis. Diabetes was only commonly found among those with APG> or =8.0 mmol l(-1), and the proportion was small until APG> or =13 mmol l(-1), although even then only 47% (95% CI 21-73%) had diabetes. Fourteen of 28 subjects with initial OGTT results suggesting diabetes were not diabetic on retesting. Inpatient mortality was higher if APG> or =7.0 (Odds ratio 2.82; CI 1.63-4.89) or the subject had known diabetes (Odds ratio 2.43; CI 1.15-4.97) compared to APG<7; there was no age or sex difference between these three groups. We conclude that, unless overtly diabetic, diagnosis of diabetes in elderly medical admissions needs later confirmation.

    Background This study aims to describe and analyze hospital admissions in Spain due to rotavirus infections among children aged 5 years or under during the period 2001–2005, along with the associated health cost. Methods To update estimates of rotavirus hospitalizations rates in Spain, we conducted a retrospective study of 5 years of national hospitalization data associated with acute gastroenteritis using the Minimum Basic Data Set. Results During the study period, a total of 17.1% of all admissions due to acute gastroenteritis of any etiology in children aged ≤ 5 years were attributable to rotavirus infection as determined by the rotavirus-specific International Classification of Diseases, ninth revision, Clinical Modification code. A mean incidence of 135 hospital admissions attributable to rotavirus per 100,000 children aged ≤ 5 years was found. Hospitalizations associated with rotavirus had a marked winter-time seasonality. The estimated cost of hospital admission attributable to rotavirus has risen from 3 million euros estimated for 2001 to almost 7 million euros estimated in 2005. Conclusion Rotavirus gastroenteritis remains an important cause of hospitalizations in Spanish children, mostly during the winter season. PMID:18397512

    The objective To determine if dental infections increase the likelihood of hospital admission among adult patients with sickle cell disease (SCD). Basic Research Design Cross-sectional analysis of data from the Nationwide Emergency Department Sample (NEDS) pooled for the years 2006 through 2008. Prevalence ratios (PR) for the effects of interest were estimated using Poisson regression with robust estimates of the variance. Participants Adults, aged 18 and over, diagnosed with SCD using ICD-9-CM codes excluding participants discharged with a code for sickle cell trait. Main outcome measure Emergency department (ED) visit disposition, dichotomised to represent whether or not the ED visit ended in admission versus being treated and released. Results Among patients having a sickle cell crisis, those with dental infections were 72% more likely to be admitted compared to those not having dental infections (PR=1.72, 95%CI 1.58-1.87). No association was observed among adult SCD patients not having a sickle crisis event. Based on preliminary data from this analysis, prevention of dental infection among patients with SCD could result in an estimated cost saving of $2.5 million dollars per year. Conclusions Having a dental infection complicated by a sickle cell crisis significantly increases the likelihood of hospital admission among adult SCD patients presenting to the ED. PMID:24151791

    Particulate matter (PM) from traffic and other sources has been associated with adverse health effects. One unifying theory is that PM, whatever its source, acts on the human body via its capacity to cause damaging oxidation reactions related to its content of pro-oxidants components. Few epidemiological studies have investigated particle oxidative potential (OP) and health. We conducted a time series analysis to assess associations between daily particle OP measures and numbers of deaths and hospital admissions for cardiovascular and respiratory diseases. During 2011 and 2012 particles with an aerodynamic diameter less than 2.5 and 10μm (PM2.5 and PM10 respectively) were collected daily on Partisol filters located at an urban background monitoring station in Central London. Particulate OP was assessed based on the capacity of the particles to oxidize ascorbate (OP(AA)) and glutathione (OP(GSH)) from a simple chemical model reflecting the antioxidant composition of human respiratory tract lining fluid. Particulate OP, expressed as % loss of antioxidant per μg of PM, was then multiplied by the daily concentrations of PM to derive the daily OP of PM mass concentrations (% loss per m(3)). Daily numbers of deaths and age- and cause-specific hospital admissions in London were obtained from national registries. Poisson regression accounting for seasonality and meteorology was used to estimate the percentage change in risk of death or admission associated with an interquartile increment in particle OP. We found little evidence for adverse associations between OP(AA) and OP(GSH) and mortality. Associations with cardiovascular admissions were generally positive in younger adults and negative in older adults with confidence intervals including 0%. For respiratory admissions there was a trend, from positive to negative associations, with increasing age although confidence intervals generally included 0%. Our study, the first to analyse daily particle OP measures and

    In December, 2010, National Health Service (NHS) England introduced national mandatory screening of all admissions for meticillin-resistant Staphylococcus aureus (MRSA). We aimed to assess the effectiveness and cost-effectiveness of this policy, from a regional or national health-care decision makers' perspective, compared with alternative screening strategies. We used an individual-based dynamic transmission model parameterised with national MRSA audit data to assess the effectiveness and cost-effectiveness of admission screening of patients in English NHS hospitals compared with five alternative strategies (including no screening, checklist-activated screening, and high-risk specialty-based screening), accompanied by patient isolation and decolonisation, over a 5 year time horizon. We evaluated strategies for different NHS hospital types (acute, teaching, and specialist), MRSA prevalence, and transmission potentials using probabilistic sensitivity analyses. Compared with no screening, mean cost per quality-adjusted life-year (QALY) of screening all admissions was £89,000-148,000 (range £68,000-222,000), and this strategy was consistently more costly and less effective than alternatives for all hospital types. At a £30,000/QALY willingness-to-pay threshold and current prevalence, only the no-screening strategy was cost effective. The next best strategies were, in acute and teaching hospitals, targeting of high-risk specialty admissions (30-40% chance of cost-effectiveness; mean incremental cost-effectiveness ratios [ICERs] £45,200 [range £35,300-61,400] and £48,000/QALY [£34,600-74,800], respectively) and, in specialist hospitals, screening these patients plus risk-factor-based screening of low-risk specialties (a roughly 20% chance of cost-effectiveness; mean ICER £62,600/QALY [£48,000-89,400]). As prevalence and transmission increased, targeting of high-risk specialties became the optimum strategy at the NHS willingness-to-pay threshold (£30,000/QALY

    There are no data on the incidence of admissions associated with alcohol withdrawal syndrome (AWS) or about its trend over time in Spain. To analyze the characteristics, incidence rates and trends over time of hospital admissions associated with AWS in Spanish public hospitals. Analysis from the Spanish public hospitals minimum basic data set of hospital admissions with AWS (CIE9-MC 291.81), alcohol withdrawal delirium (CIE9-MC 291.0) and alcohol withdrawal hallucinosis (CIE9-MC 291.3), since 1999 to 2010. We identified 56,395 admissions associated with AWS. Mean age was 50.9 (SD 12.5) and 88% were male. The most frequent admission department was Internal Medicine (24.9%). The mean hospital stay was 12.6 days (SD 14.4) and mortality was 4.7%; 62.6% of cases developed AWS during an admission for another reason, mostly due to alcohol-related pathologies. Secondary diagnoses in patients hospitalized for AWS were related to alcohol consumption in more than half of the cases. The incidence rate of admissions associated with AWS in Spain remained stable from 1999 to 2010, with a small decline in the last 3 years of the period. The communities with the highest incidence were the Canary Islands, the Balearic Islands and Galicia. The incidence rate of admissions associated with AWS in Spanish public hospitals in the period 1999-2010 has remained stable with slight changes. There are differences in the incidence of AWS among the different autonomous communities. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

    Pulmonary embolism (PE) remains a significant cause of hospital admission and health-care costs. Estimates of PE incidence came from the 1990s, and data are limited to describe trends in hospital admissions for PE over the past decade. We analyzed Nationwide Inpatient Sample data from 1993 to 2012 to identify patients admitted with PE. We included admissions with International Classification of Diseases, 9th revision, codes listing PE as the principal diagnosis as well as admissions with PE listed secondary to principal diagnoses of respiratory failure or DVT. Massive PE was defined by mechanical ventilation, vasopressors, or nonseptic shock. Outcomes included hospital lengths of stay, adjusted charges, and all-cause hospital mortality. Linear regression was used to analyze changes over time. Admissions for PE increased from 23 per 100,000 in 1993 to 65 per 100,000 in 2012 (P < .001). The percent of admissions meeting criteria for massive PE decreased (5.3% to 4.4%, P = .002), but the absolute number of admissions for massive PE increased (from 1.5 to 2.8 per 100,000, P < .001). Median length of stay decreased from 8 (interquartile range [IQR], 6-11) to 4 (IQR, 3-6) days (P < .001). Adjusted hospital charges increased from $16,475 (IQR, $10,748-$26,211) in 1993 to $25,728 (IQR, $15,505-$44,493) in 2012 (P < .001). All-cause hospital mortality decreased from 7.1% to 3.2% (P < .001), but population-adjusted deaths during admission for PE increased from 1.6 to 2.1 per 100,000 (P < .001). Total admissions and hospital charges for PE have increased over the past two decades. However, the population-adjusted admission rate has increased disproportionately to the incidence of patients with severe PE. We hypothesize that these findings reflect a concerning national movement toward more admissions of less severe PE. Copyright © 2016 American College of Chest Physicians. Published by Elsevier Inc.

    Methicillin-resistant Staphylococcus aureus (MRSA) is a nosocomial pathogen that has become increasingly prominent in hospitals and the community. HIV-positive patients may be one of the most MRSA-susceptible populations because of their immunocompromised status. At the Communicable Disease Centre, Tan Tock Seng Hospital, Singapore, we implemented a universal MRSA screening program and performed a case-control study to identify risk factors for MRSA colonization among 294 HIV patients at admission from January 2009 to January 2010. Among 54 HIV-positive patients who were MRSA positive at hospital admission, 16 (29.6%) were positive at the nares/axilla/groin (NAG; one combined swab), 14 (25.9%) were NAG and perianal positive, 3 (5.6%) were NAG and throat positive, 10 (18.5%) were NAG, perianal, and throat positive, 6 (11.1%) were throat positive, and 5 (9.3%) were perianal positive. Upon multivariate analysis, we found that age [odds ratio (OR)=1.04, 95% confidence interval (CI): 1.01-1.07, p=0.006] and CD4 count <200/μl within the past 6 months (OR=4.29, 95% CI: 1.83-10.06, p=0.001) were significant risk factors for MRSA colonization. We generated a receiver operating characteristic curve using these two variables and found that the area under the curve was 0.69, indicating that age and CD4 count <200/μl performed moderately well in discriminating between those with MRSA colonization and those without. The results of our study indicate that HIV patients of older age and reduced CD4 count may have increased risk of MRSA colonization. These risk factors may serve as indicators for cohorting or isolating HIV patients at hospital admission.

    Emergency departments (EDs) in the United States play a prominent role in hospital admissions, especially for the growing population of older adults. Home-based care, rather than hospital admission from the ED, provides an important alternative, especially for older adults who have a greater risk of adverse events, such as hospital-acquired infections, falls, and delirium. The objective of the survey was to understand emergency physicians' (EPs) perspectives on home-based care alternatives to hospitalization from the ED. Specific goals included determining how often EPs ordered home-based care, what they perceive as the barriers and motivators for more extensive ordering of home-based care, and the specific conditions and response times most appropriate for such care. A group of 1200 EPs nationwide were e-mailed a six-question survey. Participant response was 57%. Of these, 55% reported ordering home-based care from the ED within the past year as an alternative to hospital admission or observation, with most doing so less than once per month. The most common barrier was an "unsafe or unstable home environment" (73%). Home-based care as a "better setting to care for low-acuity chronic or acute disease exacerbation" was the top motivator (79%). Medical conditions EPs most commonly considered for home-based care were cellulitis, urinary tract infection, diabetes, and community-acquired pneumonia. Results suggest that EPs recognize there is a benefit to providing home-based care as an alternative to hospitalization, provided they felt the home was safe and a process was in place for dispositioning the patient to this setting. Better understanding of when and why EPs use home-based care pathways from the ED may provide suggestions for ways to promote wider adoption. Copyright © 2017 The Author(s).

    Asymptomatic Clostridium difficile carriage has a prevalence reported as high as 51-85 %; with up to 84 % of incident hospital-acquired infections linked to carriers. Accurately identifying carriers may limit the spread of Clostridium difficile. Since new technology adoption depends heavily on its economic value, we developed an analytic simulation model to determine the cost-effectiveness screening hospital admissions for Clostridium difficile from the hospital and third party payer perspectives. Isolation precautions were applied to patients testing positive, preventing transmission. Sensitivity analyses varied Clostridium difficile colonization rate, infection probability among secondary cases, contact isolation compliance, and screening cost. Screening was cost-effective (i.e., incremental cost-effectiveness ratio [ICER] ≤ $50,000/QALY) for every scenario tested; all ICER values were ≤ $256/QALY. Screening was economically dominant (i.e., saved costs and provided health benefits) with a ≥10.3 % colonization rate and ≥5.88 % infection probability when contact isolation compliance was ≥25 % (hospital perspective). Under some conditions screening led to cost savings per case averted (range, $53-272). Clostridium difficile screening, coupled with isolation precautions, may be a cost-effective intervention to hospitals and third party payers, based on prevalence. Limiting Clostridium difficile transmission can reduce the number of infections, thereby reducing its economic burden to the healthcare system.

    The Major Incident Hospital of the University Medical Centre of Utrecht has a longstanding history of preparing for the management of highly pathogenic and infectious organisms. An assessment of the hospital's preparations for an outbreak of viral hemorrhagic fever and its experience during admission of a patient with Ebola virus disease showed that the use of the buddy system, frequent training, and information sessions for staff and their relatives greatly increased the sense of safety and motivation among staff. Differing procedures among ambulance services limited the number of services used for transporting patients. Waste management was the greatest concern, and destruction of waste had to be outsourced. The admission of an Ebola patient proceeded without incident but led to considerable demands on staff. The maximum time allowed for wearing personal protective equipment was 45 minutes to ensure safety, and an additional 20 minutes was needed for recovery.

    To explore the associations between latitude and solar radiation with inflammatory bowel disease admission rates in Chile, the country with the largest variation in solar radiation in the world. This is an ecological study, which included data on all hospital-admitted population for inflammatory bowel disease between 2001 and 2012, according to different latitudes and solar radiation exposures in Chile. The data were acquired from the national hospital discharge database from the Department of Health Statistics and Information of the Chilean Ministry of Health. Between 2001 and 2012 there were 12,869 admissions due to inflammatory bowel disease (69% ulcerative colitis, 31% Crohn's disease). Median age was 36 years (IQR: 25-51); 57% were female. The national inflammatory bowel disease admission rate was 6.52 (95% CI: 6.40-6.63) per 100,000 inhabitants with increasing rates over the 12-year period. In terms of latitude, the highest admission rates for pediatric ulcerative colitis and Crohn's disease, as well as adult ulcerative colitis, were observed in the southernmost region with lowest annual solar radiation. Linear regression analysis showed that regional solar radiation was inversely associated with inflammatory bowel disease admissions in Chile (β: -.44, p = .03). Regional solar radiation was inversely associated with inflammatory bowel disease admission rates in Chile; inflammatory bowel disease admissions were highest in the southernmost region with lowest solar radiation. Our results support the potential role of vitamin D deficiency on inflammatory bowel disease flares.

    Intensive care medicine (ICM) is increasingly utilized by a growing number of critically ill patients worldwide. The reasons for this are an increasingly ageing and multimorbid population and technological improvements in ICM. Inappropriate patient admissions to the intensive care unit (ICU) can be a threat to rational resource allocation and to patient autonomy. In this study, the incidence, characteristics, and resource utilization of patients inappropriately admitted to ICUs are studied. This prospective study included all consecutive patients admitted from 01 September 2012 to 31 August 2013 to the Department of Intensive Care Medicine of a German university hospital comprised of 10 ICUs and 120 beds. Inappropriate admission was defined according to category 4B of the recommendations of the Society of Critical Care Medicine (SCCM; "futility of ICU treatment" or "ICU declined by patient") and was determined in each suspected case by structured group discussions between the study team and all involved care givers including the referring team. In all, 66 of 6452 ICU admissions (1 %) were suspected to have been inappropriate on retrospective evaluation the day after admission. In 50 patients (0.8 %), an interdisciplinary consensus was reached on the inappropriateness of the ICU admission. Of these 50 patients, 41 (82 %) had previously declined ICU treatment in principle. This information was based on the patient's presumed wish as expressed by next of kin (56 %) or in a written advanced directive (26 %). In 9 patients (18 %), ICU treatment was considered futile. In all cases, a lack of information regarding a patient's wishes or clinical prognosis was the reason for inappropriate ICU admission. In this study, patients were regularly admitted to the ICU despite their contrary wish/directive or an unfavorable clinical condition. Although this was registered in only 1 % of all admissions, optimizing preICU admission information flow with regard to

    Sudden weather changes have long been thought to be associated with negative impacts on human health, but relatively few studies have attempted to quantify these relationships. We use large 6-h changes in atmospheric pressure as a proxy for sudden weather changes and evaluate their association with hospital admissions for cardiovascular diseases (CVD). Winter and summer seasons and positive and negative pressure changes are analysed separately, using data for the city of Prague (population 1.2 million) over a 16-year period (1994-2009). We found that sudden pressure drops in winter are associated with significant rise in hospital admissions. Increased CVD morbidity was observed neither for pressure drops in summer nor pressure increases in any season. Analysis of synoptic weather maps shows that large pressure drops in winter are associated with strong zonal flow and rapidly moving low-pressure systems with centres over northern Europe and atmospheric fronts affecting western and central Europe. Analysis of links between passages of strong atmospheric fronts and hospital admissions, however, shows that the links disappear if weather changes are characterised by frontal passages. Sudden pressure drops in winter are associated also with significant excess CVD mortality. As climate models project strengthening of zonal circulation in winter and increased frequency of windstorms, the negative effects of such weather phenomena and their possible changes in a warmer climate of the twenty-first century need to be better understood, particularly as their importance in inducing excess morbidity and mortality in winter may increase compared to cold spells.

    To investigate the relationship between intelligence measured at ages 18-19 and later alcohol-related hospital admission and mortality among men, while controlling for possible confounders. Cohort study. A total of 49,321 Swedish men who were conscripted for military training in 1969-70 and followed until 2007. Intelligence quotient (IQ) measured at conscription is the exposure, while alcohol-related hospital admission and death are the two outcomes. Adjustments for following variables were made: early life circumstances [childhood socio-economic position (SEP), father's drinking], mental health, social adjustment and behavioural factors measured at age 18 (psychiatric diagnosis, contact with police and child care, low emotional control, daily smoking, risky use of alcohol) and adult social position (attained education, SEP and income at age 40). IQ had an inverse and graded association with later alcohol-related problems. For alcohol-related hospital admissions the crude hazard ratio (HR) was 1.29 (95% CI = 1.26-1.31) and for alcohol-related mortality it was 1.21 (95% CI = 1.17-1.24) for every one point decrease on the nine-point IQ scale. Adjustment for risk factors measured at age 18 attenuated the association somewhat for both outcomes. After adjustment for social position as adult, the HR was considerably lower resulting in a HR of 1.06 (95% CI = 1.02-1.10) for alcohol-related hospital admissions and 1.01 (95% CI = 0.95-1.08) for alcohol-related mortality. In Swedish men there is an association between IQ in early adulthood and later alcohol-related hospital admission and death. Social position as adult could be an important contributory factor. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

    Medication discrepancies at hospital admission is an extensive problem and knowledge is limited regarding improvement strategies. To investigate the effect of teaching and checklist implementation on accuracy of medication history recording during hospitalization. Patients admitted to an internal medicine ward were prospectively included in two consecutive periods. Between the periods, non-mandatory teaching lessons were provided and a checklist assisting medication history recording implemented. Discrepancies between the recorded medications at admission and the patient's actual drug use, as revealed by pharmacist-conducted medication reconciliation, were compared between the periods. The primary endpoint was difference between the periods in proportion of patients with minimum one discrepancy. Difference in median number of discrepancies was included as a secondary endpoint. 56 and 119 patients were included in period 1 (P1) and period 2 (P2), respectively. There was no significant difference in proportion of patients with minimum one discrepancy in P2 (68.9 %) versus P1 (76.8 %, p = 0.36), but a tendency of lower median number of discrepancies was observed in P2 than P1, i.e. 1 and 2, respectively (p = 0.087). More powerful strategies than non-mandatory teaching activities and checklist implementation are required to achieve sufficient improvements in medication history recording during hospitalization.

    Background Inpatient treatment is an expensive way of caring for people with acute psychiatric disorders. It has been proposed that many of those currently treated as inpatients could be cared for in acute psychiatric day hospitals. Objectives To assess the effects of day hospital versus inpatient care for people with acute psychiatric disorders. Search methods We searched the Cochrane Schizophrenia Group Trials Register (June 2010) which is based on regular searches of MEDLINE, EMBASE, CINAHL and PsycINFO. We approached trialists to identify unpublished studies. Selection criteria Randomised controlled trials of day hospital versus inpatient care, for people with acute psychiatric disorders. Studies were ineligible if a majority of participants were under 18 or over 65, or had a primary diagnosis of substance abuse or organic brain disorder. Data collection and analysis Two review authors independently extracted and cross-checked data. We calculated risk ratios (RR) and 95% confidence intervals (CI) for dichotomous data. We calculated weighted or standardised means for continuous data. Day hospital trials tend to present similar outcomes in slightly different formats, making it difficult to synthesise data. We therefore sought individual patient data so that we could re-analyse outcomes in a common format. Main results Ten trials (involving 2685 people) met the inclusion criteria. We obtained individual patient data for four trials (involving 646 people). We found no difference in the number lost to follow-up by one year between day hospital care and inpatient care (5 RCTs, n = 1694, RR 0.94 CI 0.82 to 1.08). There is moderate evidence that the duration of index admission is longer for patients in day hospital care than inpatient care (4 RCTs, n = 1582, WMD 27.47 CI 3.96 to 50.98). There is very low evidence that the duration of day patient care (adjusted days/month) is longer for patients in day hospital care than inpatient care (3 RCTs, n = 265, WMD 2.34 days

    Background Screening at hospital admission for carriage of methicillin-resistant Staphylococcus aureus (MRSA) has been proposed as a strategy to reduce nosocomial infections. The objective of this study was to determine the long-term costs and health benefits of selective and universal screening for MRSA at hospital admission, using both PCR-based and chromogenic media-based tests in various settings. Methodology/Principal Findings A simulation model of MRSA transmission was used to determine costs and effects over 15 years from a US healthcare perspective. We compared admission screening together with isolation of identified carriers against a baseline policy without screening or isolation. Strategies included selective screening of high risk patients or universal admission screening, with PCR-based or chromogenic media-based tests, in medium (5%) or high nosocomial prevalence (15%) settings. The costs of screening and isolation per averted MRSA infection were lowest using selective chromogenic-based screening in high and medium prevalence settings, at $4,100 and $10,300, respectively. Replacing the chromogenic-based test with a PCR-based test costs $13,000 and $36,200 per additional infection averted, and subsequent extension to universal screening with PCR would cost $131,000 and $232,700 per additional infection averted, in high and medium prevalence settings respectively. Assuming $17,645 benefit per infection averted, the most cost-saving strategies in high and medium prevalence settings were selective screening with PCR and selective screening with chromogenic, respectively. Conclusions/Significance Admission screening costs $4,100–$21,200 per infection averted, depending on strategy and setting. Including financial benefits from averted infections, screening could well be cost saving. PMID:21483492

    Background Medication discrepancies often occur at transition of care such as hospital admission and discharge. Obtaining a complete and accurate medication history on admission is essential as further treatment is based on it. Objective The goal of this study was to reduce the proportion of patients with at least one medication discrepancy in the medication history at admission by implementing an IT-guided checklist. Setting Surgery ward focused on vascular and visceral surgery at a Swiss Cantonal Hospital. Method The study was divided into two phases, before and after implementation of an IT-guided checklist. For both phases a pharmacist collected and compared the medication history (defined as gold standard) with that of the admitting physician. Medication discrepancies were subdivided in omissions and commissions, incorrect medications or dose changes, and incorrect dosage forms or strength. Main outcome measure The proportion of patients with at least one medication discrepancy in the medication history before and after intervention was assessed. Results Out of 415 admissions, 228 patients that met the inclusion criteria were enrolled in the study, 113 before and 115 patients after intervention. After intervention, medication discrepancies declined from 69.9 to 29.6% (p < 0.0001) of patients, the mean medication discrepancy per patient was reduced from 2.3 to 0.6 (p < 0.0001), and the most common error, omission of a regularly used medication, was reduced from 76.4 to 44.1% (p < 0.001). Conclusion The implementation of the IT-guided checklist is associated with a significant reduction of medication discrepancies at admission and potentially improves the medication safety for the patient.

    The study objective was to explore emergency physicians' (EP) awareness, willingness, and prior experience regarding transitioning patients to home-based healthcare following emergency department (ED) evaluation and treatment; and to explore patient selection criteria, processes, and services that would facilitate use of home-based healthcare as an alternative to hospitalization. We provided a five-question survey to 52 EPs, gauging previous experience referring patients to home-based healthcare, patient selection, and motivators and challenges when considering home-based options as an alternative to admission. In addition, we conducted three focus groups and four interviews. Of participating EPs, 92% completed the survey, 38% reported ordering home-based healthcare from the ED as an alternative to admission, 90% ranked cellulitis among the top three medical conditions for home-based healthcare, 90% ranked "reduce unnecessary hospitalizations and observation stays" among their top three perceived motivators for using home-based care, and 77% ranked "no existing process in place to refer to home-based care" among their top three perceived barriers. Focus group and interview themes included the need for alternatives to admission; the longer-term benefits of home-based healthcare; the need for streamlined transition processes; and the need for highly qualified home-care staff capable of responding the same day or within 24 hours. The study found that EPs are receptive to referring patients for home-based healthcare following ED treatment and believe people with certain diagnoses are likely to benefit, with the dominant barrier being the absence of an efficient referral process.

    Limited data exist on the burden of serious adverse drug reactions (ADRs) in sub-Saharan Africa, which has high HIV and tuberculosis prevalence. We determined the proportion of adult admissions attributable to ADRs at 4 hospitals in South Africa. We characterized drugs implicated in, risk factors for, and the preventability of ADR-related admissions.We prospectively followed patients admitted to 4 hospitals' medical wards over sequential 30-day periods in 2013 and identified suspected ADRs with the aid of a trigger tool. A multidisciplinary team performed causality, preventability, and severity assessment using published criteria. We categorized an admission as ADR-related if the ADR was the primary reason for admission.There were 1951 admissions involving 1904 patients: median age was 50 years (interquartile range 34-65), 1057 of 1904 (56%) were female, 559 of 1904 (29%) were HIV-infected, and 183 of 1904 (10%) were on antituberculosis therapy (ATT). There were 164 of 1951 (8.4%) ADR-related admissions. After adjustment for age and ATT, ADR-related admission was independently associated (P ≤ 0.02) with female sex (adjusted odds ratio [aOR] 1.51, 95% confidence interval [95% CI] 1.06-2.14), increasing drug count (aOR 1.14 per additional drug, 95% CI 1.09-1.20), increasing comorbidity score (aOR 1.23 per additional point, 95% CI 1.07-1.41), and use of antiretroviral therapy (ART) if HIV-infected (aOR 1.92 compared with HIV-negative/unknown, 95% CI 1.17-3.14). The most common ADRs were renal impairment, hypoglycemia, liver injury, and hemorrhage. Tenofovir disoproxil fumarate, insulin, rifampicin, and warfarin were most commonly implicated, respectively, in these 4 ADRs. ART, ATT, and/or co-trimoxazole were implicated in 56 of 164 (34%) ADR-related admissions. Seventy-three of 164 (45%) ADRs were assessed as preventable.In our survey, approximately 1 in 12 admissions was because of an ADR. The range of ADRs and implicated drugs reflect South Africa's high HIV

    Chronic disease management programs (CDMPs) were introduced in Australia to reduce unnecessary health care utilization by the growing population with chronic conditions; however, evidence of effectiveness is needed. This study evaluated the impact of a comprehensive CDMP, My Health Guardian (MHG), on rate of hospital admissions, readmissions, and average length of hospital stay (ALOS) for insured individuals with heart disease or diabetes. Primary outcomes were assessed through retrospective comparison of members in MHG (treatment; n=5053) to similar nonparticipating members (comparison; n=23,077) using a difference-in-differences approach with the year before program commencement serving as baseline and the subsequent 12 or 18 months serving as the program periods. All outcomes were evaluated for the total study population and for disease-matched subgroups (heart disease and diabetes). Statistical tests were performed using multivariate regression controlling for age, sex, number of chronic diseases, and past hospitalization status. After both 12 and 18 months, treatment members displayed decreases in admissions (both, P≤0.001) and readmissions (both, P≤0.01), and ALOS after 18 months (P≤0.01) versus the comparison group; magnitude of impact increased over time for these 3 measures. All outcomes for both disease-matched subgroups directionally mirrored the total study group, but the diabetes subgroup did not achieve significance for readmissions or ALOS. Within the treatment group, admissions decreased with increasing care calls to members (12 and 18 months, P<0.0001). These results show that MHG successfully reduced the frequency and duration of hospital admissions and presents a promising approach to reduce the burden associated with hospitalizations in populations with chronic disease.

  12. Predicting Appropriate Admission of Bronchiolitis Patients in the Emergency Department: Rationale and Methods.

    2016-03-07

    In young children, bronchiolitis is the most common illness resulting in hospitalization. For children less than age 2, bronchiolitis incurs an annual total inpatient cost of $1.73 billion. Each year in the United States, 287,000 emergency department (ED) visits occur because of bronchiolitis, with a hospital admission rate of 32%-40%. Due to a lack of evidence and objective criteria for managing bronchiolitis, ED disposition decisions (hospital admission or discharge to home) are often made subjectively, resulting in significant practice variation. Studies reviewing admission need suggest that up to 29% of admissions from the ED are unnecessary. About 6% of ED discharges for bronchiolitis result in ED returns with admission. These inappropriate dispositions waste limited health care resources, increase patient and parental distress, expose patients to iatrogenic risks, and worsen outcomes. Existing clinical guidelines for bronchiolitis offer limited improvement in patient outcomes. Methodological shortcomings include that the guidelines provide no specific thresholds for ED decisions to admit or to discharge, have an insufficient level of detail, and do not account for differences in patient and illness characteristics including co-morbidities. Predictive models are frequently used to complement clinical guidelines, reduce practice variation, and improve clinicians' decision making. Used in real time, predictive models can present objective criteria supported by historical data for an individualized disease management plan and guide admission decisions. However, existing predictive models for ED patients with bronchiolitis have limitations, including low accuracy and the assumption that the actual ED disposition decision was appropriate. To date, no operational definition of appropriate admission exists. No model has been built based on appropriate admissions, which include both actual admissions that were necessary and actual ED discharges that were unsafe. The

    The traditional Medicare program requires an enrollee to have a hospital stay of at least three consecutive calendar days to qualify for coverage of subsequent postacute care in a skilled nursing facility. This long-standing policy, implemented to discourage premature discharges from hospitals, might now be inappropriately lengthening hospital stays for patients who could be transferred sooner. To assess the implications of eliminating the three-day qualifying stay requirement, we compared hospital and postacute skilled nursing facility utilization among Medicare Advantage enrollees in matched plans that did or did not eliminate that requirement in 2006–10. Among hospitalized enrollees with a skilled nursing facility admission, the mean hospital length-of-stay declined from 6.9 days to 6.7 days for those no longer subject to the qualifying stay but increased from 6.1 to 6.6 days among those still subject to it, for a net decline of 0.7 day when the three-day stay requirement was eliminated. The elimination was not associated with more hospital or skilled nursing facility admissions or with longer lengths-of-stay in a skilled nursing facility. These findings suggest that eliminating the three-day stay requirement conferred savings on Medicare Advantage plans and that study of the requirement in traditional Medicare plans is warranted.

    Electronic linkage of UK cohorts to routinely collected National Health Service (NHS) records provides virtually complete follow-up for cause-specific hospital admissions and deaths. The reliability of dementia diagnoses recorded in NHS hospital data is not well documented. For a sample of Million Women Study participants in England we compared dementia recorded in routinely collected NHS hospital data (Hospital Episode Statistics: HES) with dementia recorded in two separate sources of primary care information: a primary care database [Clinical Practice Research Datalink (CPRD), n = 340] and a survey of study participants' General Practitioners (GPs, n = 244). Dementia recorded in HES fully agreed both with CPRD and with GP survey data for 85% of women; it did not agree for 1 and 4%, respectively. Agreement was uncertain for the remaining 14 and 11%, respectively; and among those classified as having uncertain agreement in CPRD, non-specific terms compatible with dementia, such as 'memory loss', were recorded in the CPRD database for 79% of the women. Agreement was significantly better (p < 0.05 for all comparisons) for women with HES diagnoses for Alzheimer's disease (95 and 94% agreement with any dementia for CPRD and GP survey, respectively) and for vascular dementia (88 and 88%, respectively) than for women with a record only of dementia not otherwise specified (70 and 72%, respectively). Dementia in the same woman was first mentioned an average 1.6 (SD 2.6) years earlier in primary care (CPRD) than in hospital (HES) data. Age-specific rates for dementia based on the hospital admission data were lower than the rates based on the primary care data, but were similar if the delay in recording in HES was taken into account. Dementia recorded in routinely collected NHS hospital admission data for women in England agrees well with primary care records of dementia assessed separately from two different sources, and is sufficiently reliable for epidemiological

    Background Previous studies have suggested that there may be an association between vitamin D deficiency and the risk of developing immune-mediated diseases. Methods We analyzed a database of linked statistical records of hospital admissions and death registrations for the whole of England (from 1999 to 2011). Rate ratios for immune-mediated disease were determined, comparing vitamin D deficient cohorts (individuals admitted for vitamin D deficiency or markers of vitamin D deficiency) with comparison cohorts. Results After hospital admission for either vitamin D deficiency, osteomalacia or rickets, there were significantly elevated rates of Addison’s disease, ankylosing spondylitis, autoimmune hemolytic anemia, chronic active hepatitis, celiac disease, Crohn’s disease, diabetes mellitus, pemphigoid, pernicious anemia, primary biliary cirrhosis, rheumatoid arthritis, Sjogren’s syndrome, systemic lupus erythematosus, thyrotoxicosis, and significantly reduced risks for asthma and myxoedema. Conclusions This study shows that patients with vitamin D deficiency may have an increased risk of developing some immune-mediated diseases, although we cannot rule out reverse causality or confounding. Further study of these associations is warranted and these data may aid further public health studies. PMID:23885887

    We investigated tenant healthcare utilisation associated with upgrading 8558 council houses to a national quality standard. Homes received multiple internal and external improvements and were analysed using repeated measures of healthcare utilisation. The primary outcome was emergency hospital admissions for cardiorespiratory conditions and injuries for residents aged 60 years and over. Secondary outcomes included each of the separate conditions, for tenants aged 60 and over, and for all ages. Council home address and intervention records for eight housing cointerventions were anonymously linked to demographic data, hospital admissions and deaths for individuals in a dynamic cohort. Counts of health events were analysed using multilevel regression models to investigate associations between receipt of each housing improvement, adjusting for potential confounding factors and regional trends. Residents aged 60 years and over living in homes when improvements were made were associated with up to 39% fewer admissions compared with those living in homes that were not upgraded (incidence rate ratio=0.61, 95% CI 0.53 to 0.72). Reduced admissions were associated with electrical systems, windows and doors, wall insulation, and garden paths. There were small non-significant reductions for the primary outcome associated with upgrading heating, adequate loft insulation, new kitchens and new bathrooms. Results suggest that hospital admissions can be avoided through improving whole home quality standards. This is the first large-scale longitudinal evaluation of a whole home intervention that has evaluated multiple improvement elements using individual-level objective routine health data. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    To explore the experiences of patients with advanced Chronic Obstructive Pulmonary Disease (COPD) and lung cancer, their carers and healthcare professionals following emergency admission to acute care hospital. Emergency admissions of people with lung cancer and COPD have increased and there is global concern about the number of patients who die in hospital. The experience of patients with advanced lung cancer and COPD admitted to hospital as an emergency when nearing the end of life has not previously been investigated. Qualitative critical incident case study. Semistructured interviews were conducted with 39 patients (15 with COPD and 24 with lung cancer), 20 informal carers and 50 healthcare professionals, exploring patients' experiences of emergency hospital admission. Interviews took place after admission and following discharge. Participants nominated relatives and healthcare professionals for interview. Data were analysed thematically. Patients were satisfied with their 'emergency' care but not the care they received once their initial symptoms had been stabilised. The poorer quality care they experienced was characterised by a lack of attention to their fundamental needs, lack of involvement of the family, poor communication about care plans and a lack of continuity between primary and secondary care. A conceptual model of 'spectacular' and 'subtacular' trajectories of care was used to relate the findings to the wider context of health care provision. The complex nature of illness for patients with advanced respiratory disease makes emergency hospital admissions likely. Whilst patients (with COPD and lung cancer) were satisfied with care in the acute 'spectacular' phase of their admission, more attention needs to be given to the continuing care needs of patients in the 'subtacular' phase. This is the first study to explore the patient experience of acute care following an emergency admission and identifies where there is potential for care to be improved.

    In many countries, conflicting gradients in alcohol consumption and alcohol-associated mortality have been observed. To understand this 'alcohol harm paradox' we analysed the socio-economic gradient in alcohol-associated hospital admissions to test whether it was greater in conditions which were: (1) chronic (associated with long-term drinking) and partially alcohol-attributable, (2) chronic and wholly alcohol-attributable, (3) acute (associated with intoxication) and partially alcohol-attributable and (4) acute and wholly alcohol-attributable. Our aim was to clarify how (1) drinking patterns (e.g. intoxication linked to acute admissions or dependence linked to chronic conditions) and (2) non-alcohol causes (e.g. smoking and poor diet which are risks for partially alcohol-attributable conditions) contribute to the paradox. Regression analysis testing the modifying effects of condition-group (1-4 above) and sex on the relationship between area-based deprivation and admissions. England, April 2010-March 2013. A total of 9 239 629 English hospital admissions where a primary or secondary cause was one of 36 alcohol-associated conditions. Admissions by condition and deciles of Index of Multiple Deprivation (IMD). Socio-economic gradient measured as the relative index of inequality (RII, the slope of a linear regression of IMD on admissions adjusted for overall admission rate). Conditions were categorized by ICD-10 code. A socio-economic gradient in hospitalizations was seen for all conditions, except partially attributable chronic conditions. The gradient was significantly steeper for conditions which were wholly attributable to alcohol and for acute conditions than for conditions partially alcohol-attributable and for chronic conditions. Gradients were steeper for men than for women in cases of wholly alcohol attributable conditions. There is a socio-economic gradient in English hospital admission for most alcohol-associated conditions. The greatest inequalities are in

    Despite emerging data of cost savings under palliative care in various regions, no such data have been generated in response to the high burden of terminal illness in Africa. This evaluation of a novel hospital-based palliative care service for patients with advanced organ failure in urban South Africa aimed to determine whether the service reduces admissions and increases home death rates compared with the same fixed time period of standard hospital care. Data on admissions and place of death were extracted from routine hospital activity records for a fixed period before death, using standard patient daily expense rates. Data from the first 56 consecutive deaths under the new service (intervention group) were compared with 48 consecutive deaths among patients immediately before the new service (historical controls). Among the intervention and control patients, 40 of 56 (71.4%) and 47 of 48 (97.9%), respectively, had at least one admission (P < 0.001). The mean number of admissions for the intervention and control groups was 1.39 and 1.98, respectively (P < 0.001). The mean total number of days spent admitted for intervention and control groups was 4.52 and 9.3 days, respectively (P < 0.001). For the intervention and control patients, a total of 253 and 447 admission days were recorded, respectively, with formal costs of $587 and $1209, respectively. For the intervention and control groups, home death was achieved by 33 of 56 (58.9%) and nine of 48 (18.8%), respectively (P ≤ 0.001). These data demonstrate that an outpatient hospital-based service reduced admissions and improved the rate of home deaths and offers a feasible and cost-effective model for such settings.

    OBJECTIVE: To determine whether the reported higher case fatality in hospital after an acute cardiac event in women can be explained by sex differences in mortality before admission and in baseline risk factors. DESIGN: Analyses of data from a community based coronary heart disease register. SETTING: Auckland region, New Zealand. SUBJECTS: 5106 patients aged 25-64 years with an acute cardiac event leading to coronary death or definite myocardial infarction within 28 days of onset, occurring between 1986 and 1992. MAIN OUTCOME MEASURES: Case fatality before admission, 28 day case fatality for patients in hospital, and total case fatality after an acute cardiac event. RESULTS: Despite a more unfavourable risk profile women tended to have lower case fatality before admission than men (crude odds ratio 0.88; 95% confidence interval 0.77 to 1.02). Adjustment for age, living arrangements, smoking, medical history, and treatment increased the effect of sex (0.72; 0.60 to 0.86). After admission to hospital, women had a higher case fatality than men (1.76; 1.43 to 2.17), but after adjustment for confounders this was reduced to 1.18 (0.89 to 1.58). Total case fatality 28 days after an acute cardiac event showed no significant difference between men and women (0.85; 0.70 to 1.02) CONCLUSIONS: The higher case fatality after an acute cardiac event in women admitted to hospital is largely explained by differences in living status, history, and medical treatment and is balanced by a lower case fatality before admission.

    Infection with Haemophilus influenzae, Neisseria meningitidis, and Streptococcus pneumoniae causes substantial mortality and long-term morbidity in children. We know of no study to assess the long-term trends in hospital admission rates for meningitis and septicaemia caused by these pathogens in children in England. We aimed to do such a study using routinely reported data in England. In this population-based observational study, we used datasets that include routinely collected administrative statistics for hospital care: the Hospital In-Patient Enquiry (data for England from 1968 to 1985), the Hospital Episode Statistics dataset (data for England from 1989 onwards), and the Oxford record linkage study (data for Oxfordshire and surrounding areas from 1963 to 2011). We analysed annual age-specific and age-standardised admission rates in children younger than 15 years with H influenzae, meningococcal and pneumococcal meningitis, and septicaemia. We saw a reduction in hospital admission rates for childhood invasive bacterial disease after the introduction of conjugate vaccines against H influenzae, N meningitidis, and S pneumoniae in England. Annual incidence of H influenzae meningitis per 100,000 children decreased from 6·72 admissions (95% CI 6·18-7·26) in 1992 to 0·39 admissions (0·26-0·52) in 1994, after the introduction of routine H influenzae type b vaccination. We saw a small rise in admissions in the early 2000s, peaking at 1·24 admissions per 100,000 children (0·99-1·48) in 2003, which decreased to 0·28 per 100,000 children (0·17-0·39) by 2008 after the introduction of catch-up (2003) and routine (2006) booster programmes for young children. Meningococcal disease increased during the 1990s, reaching a peak in 1999, with 34·54 admissions (33·30-35·78) per 100,000 children. Hospital admissions decreased after the meningococcal serogroup C vaccine was introduced in 1999 and was 12·40 admissions (11·68-13·12) per 100,000 in 2011. Admissions for

    To investigate patient and hospital characteristics associated with increased cost and length of stay in the inpatient management of epistaxis. Retrospective cross-sectional study of the 2008 to 2012 National (Nationwide) Inpatient Sample. Patient and hospital characteristics of epistaxis admissions were analyzed. Multiple linear regression analysis was used to ascertain variables associated with increased cost and length of hospital stay. Variables significantly associated with high cost were further analyzed to determine the contribution of operative intervention and total procedures to cost. A total of 16,828 patients with an admitting diagnosis of epistaxis were identified. The average age was 67.5; 52.3% of the patients were male; 73.3% of the patients were Caucasian; and 70.7% of the hospital stays were government funded. The average length of stay was 3.24 days, and average hospitalization cost was $6,925. Longer length of stay was associated with black race, alcohol abuse, sinonasal disease, renal disease, Medicaid, and care at a northeastern U.S. hospital. Increased hospitalization costs of > $1,000 were associated with Asian/Pacific Islander race; sinonasal disease; renal disease; top income quartile; and care at urban teaching, northeastern, and western hospitals in the United States. High costs were predicted by procedural intervention in patients with comorbid alcohol abuse, sinonasal disease, renal disease, patients with private insurance, and patients managed at large hospitals. Although hospitalization costs are complex and multifactorial, we were able to identify patient and hospital characteristics associated with high costs in the management of epistaxis. Early identification and intervention, combined with implementation of targeted hospital management protocols, may improve outcomes and reduce financial burden. 2C. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    This study analyzes hospitalizations due to ambulatory care-sensitive conditions with a focus on infectious and parasitic diseases (IPDs) and validates the Hospital Information System, Brazilian Unified National Health System (SIH/SUS) for recording hospitalizations due to ambulatory care-sensitive conditions in a hospital in the Federal District, Brazil, in 2012. The study estimates the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the SIH for recording hospitalizations due to ambulatory care-sensitive conditions, with the patient's medical file as the gold standard. There were 1,604 hospitalizations for hospitalizations due to ambulatory care-sensitive conditions (19.6%, 95%CI: 18.7-20.5), and the leading IPDs were renal and urinary tract infection, infection of the skin and subcutaneous tissue, and infectious gastroenteritis. IPDs were the leading cause of hospitalization in the 20 to 29-year age bracket and caused 28 deaths. Sensitivity was 70.1% (95%CI: 60.5-79.7), specificity 88.4% (95%CI: 85.6-91.2), PPV = 51.7% (95%CI: 42.7-60.7), and NPV = 94.3% (95%CI: 92.2-96.4). The findings for admissions due to ACSCs in this hospital were similar to those of other studies, featuring admissions for IPDs. The SIH/SUS database was more specific than sensitive.

    Since 2005, the Government of Ghana and its partners, in concerted efforts to control malaria, scaled up the use of artemisinin-based combination therapy (ACT) and insecticide-treated nets (ITNs). Beginning in 2011, a mass campaign of long-lasting insecticidal nets (LLINs) was implemented, targeting all the population. The impact of these interventions on malaria cases, admissions and deaths was assessed using data from district hospitals. Records of malaria cases and deaths and availability of ACT in 88 hospitals, as well as at district level, ITN distribution, and indoor residual spraying were reviewed. Annual proportion of the population potentially protected by ITNs was estimated with the assumption that each LLIN covered 1.8 persons for 3 years. Changes in trends of cases and deaths in 2015 were estimated by segmented log-linear regression, comparing trends in post-scale-up (2011-2015) with that of pre-scale-up (2005-2010) period. Trends of mortality in children under 5 years old from population-based household surveys were also compared with the trends observed in hospitals for the same time period. Among all ages, the number of outpatient malaria cases (confirmed and presumed) declined by 57% (95% confidence interval [CI], 47-66%) by first half of 2015 (during the post-scale-up) compared to the pre-scale-up (2005-2010) period. The number of microscopically confirmed cases decreased by 53% (28-69%) while microscopic testing was stable. Test positivity rate (TPR) decreased by 41% (19-57%). The change in malaria admissions was insignificant while malaria deaths fell significantly by 65% (52-75%). In children under 5 years old, total malaria outpatient cases, admissions and deaths decreased by 50% (32-63%), 46% (19-75%) and 70% (49-82%), respectively. The proportion of outpatient malaria cases, admissions and deaths of all-cause conditions in both all ages and children under five also fell significantly by >30%.

    Some evidence indicates the deterioration of the cardiovascular system during space storms. It is plausible that the space weather conditions during and after hospital admission may affect the risk of coronary events in patients with acute coronary syndromes (ACS). We analyzed the data of 1400 ACS patients who were admitted to the Hospital Lithuanian University of Health Sciences, and who survived for more than 4 days. We evaluated the associations between geomagnetic storms (GS), solar proton events (SPE), and solar flares (SF) that occurred 0-3 days before and after hospital admission and the risk of cardiovascular death (CAD), non-fatal ACS, and coronary artery bypass grafting (CABG) during a period of 1 year; the evaluation was based on the multivariate logistic model, controlling for clinical data. After adjustment for clinical variables, GS occurring in conjunction with SF 1 day before admission increased the risk of CAD by over 2.5 times. GS 2 days after SPE occurred 1 day after admission increased the risk of CAD and CABG by over 2.8 times. The risk of CABG increased by over 2 times in patients admitted during the day of GS and 1 day after SPE. The risk of ACS was by over 1.63 times higher for patients admitted 1 day before or after solar flares.

    Paraffin (kerosene) ingestion is the most common form of childhood poisoning in most developing countries. Despite this, there is a paucity of toxicoepidemiological data which could potentially be used in measures to reduce preventable exposures. This article reports on the patterns of hospital admissions resulting from paraffin exposure in Zimbabwe. All cases of paraffin ingestion admitted to eight major referral hospitals in Zimbabwe from January 1998 to December 1999 (inclusive), were identified using ICD-9 codes and ward registers and relevant information recorded on a standard data collection sheet. There were a total of 327 admissions due to oral exposure to paraffin. This represented 11.8% of all the poisoning admissions to the eight study hospitals. Most exposures (300; 91.7%) occurred accidentally, with only 6.7% resulting from deliberate ingestion of the chemical. The median age on admission was 2 years (interquartile range [IQR] 1-2 yrs) with over 85% of cases in the 0-5 year age range and less than 10% above the age of 12 years. The median age on admission was much higher for deliberate self poisoning (23 yrs; IQR 19-26 yrs) compared to that for accidental poisoning (1.5 yrs; IQR 1-2 yrs). Accidental poisoning from paraffin occurred throughout the year. Over three-quarters of patients received an antibiotic either alone, or in combination with another antibiotic or drug. Paracetamol (24.3%) was the next most commonly encountered treatment. The case fatality rate (CFR) was therefore 0.3 deaths per 100 admissions (95% Confidence Interval 0.0-1.7). Paraffin ingestion remains an important cause of poisoning morbidity in Zimbabwe throughout the year, particularly in children. Clinical management appears adequate with a low mortality, although there may be overuse of prophylactic antibiotics. Further study specific to this area is warranted to prevent unnecessary antibiotic use and wastage of resources.

    The increased prevalence of diabetes and its significant impact on use of health care services, particularly hospitals, is a concern for health planners. This paper explores the risk factors for all-cause hospitalisation and the excess risk due to diabetes in a large sample of older Australians. The study population was 263,482 participants in the 45 and Up Study. The data assessed were linked records of hospital admissions in the 12 months following completion of a baseline questionnaire. All cause and ambulatory care sensitive admission rates and length of stay were examined. The associations between demographic characteristics, socioeconomic status, lifestyle factors, and health and wellbeing and risk of hospitalisation were explored using zero inflated Poisson (ZIP) regression models adjusting for age and gender. The ratios of adjusted relative rates and 95% confidence intervals were calculated to determine the excess risk due to diabetes. Prevalence of diabetes was 9.0% (n = 23,779). Age adjusted admission rates for all-cause hospitalisation were 631.3 and 454.8 per 1,000 participant years and the mean length of stay was 8.2 and 7.1 days respectively for participants with and without diabetes. In people with and without diabetes, the risk of hospitalisation was associated with age, gender, household income, smoking, BMI, physical activity, and health and wellbeing. However, the increased risk of hospitalisation was attenuated for participants with diabetes who were older, obese, or had hypertension or hyperlipidaemia and enhanced for those participants with diabetes who were male, on low income, current smokers or who had anxiety or depression. This study is one of the few studies published to explore the impact of diabetes on hospitalisation in a large non-clinical population, the 45 and Up Study. The attenuation of risk associated with some factors is likely to be due to correlation between diabetes and factors such as age and obesity. The increased risk

    In-hospital mortality (IHM) is an indicator of the quality of care provided. The two most widely used scores for predicting IHM by International Classification of Diseases (ICD) codes are the Elixhauser (EI) and the Charlson Comorbidity indexes. Our aim was to obtain new measures based on internal medicine ICD codes for the original EI, to detect risk for IHM. This single-center retrospective study included hospital admissions for any cause in the department of internal medicine between January 1, 2000, and December 31, 2013, recorded in the hospital database. The EI was calculated for evaluation of comorbidity, then we added age, gender and diagnosis of ischemic heart disease. IHM was our outcome. Only predictors positively associated with IHM were taken into consideration and the Sullivan's method was applied in order to modify the parameter estimates of the regression model into an index. We analyzed 75,586 admissions (53.4% females) and mean age was 72.7±16.3years. IHM was 7.9% and mean score was 12.1±7.6. The points assigned to each condition ranged from 0 to 16, and the possible range of the score varied between 0 and 89. In our population the score ranged from 0 to 54, and it was higher in the deceased group. Receiver operating characteristic curve of the new score was 0.721 (95% CI 0.714-0.727, p<0.001). In order to make prognostic assessment, the use of a score could be of help in targeting interventions in older adults, identifying subjects at high risk for IHM.

    Crimean-Congo hemorrhagic fever (CCHF) has been reported from all provinces of Pakistan. Little is known about the seasonal variations in the disease and its association with weather conditions. In this study, we explored time-series data about monthly number of CCHF admissions (2007-2010) in three public sector hospitals of Quetta—the capital city of Baluchistan province of Pakistan. Cosinor analysis was carried out to investigate seasonality in the data. To assess the effect of average monthly ambient temperature (°C) on disease, a distributed lag nonlinear model (DLNM) was applied. Cosinor model revealed statistically significant seasonality in monthly number of CCHF patients admitted to the study hospitals. The estimated amplitude was 3.24 cases per month with phase in mid-June and low point in mid-December. DLNM confirmed nonlinear and delayed effect of temperature on hospital admissions. At a lag of 2 months, the cumulative relative risk was more than 1 at temperature at 18.37 °C and above. In addition, relative risk was significantly high at 60th (21.98 °C), 70th (24.50 °C), 80th (27.33 °C), and 90th (29.25 °C) percentiles of temperature (relative to median value, 18.37 °C). Inclusion of Eid-al-Adha as a predictor did not improve the fitness of DLNM. Based on our analysis, we concluded significant seasonality in CCHF hospital admissions. Our findings also suggested average monthly ambient temperature (°C) as a significant predictor of CCHF hospitalizations. DLNM presented in this study may be improved with inclusion of other possible time-varying predictors particularly meteorological conditions of this region.

    The process of admitting patients from the emergency department (ED) to an academic internal medicine (AIM) service in a community teaching hospital is one fraught with variability and disorder. This results in an inconsistent volume of patients admitted to academic versus private hospitalist services and results in frustration of both ED and AIM clinicians. We postulated that implementation of a mobile application (app) would improve provider satisfaction and increase admissions to the academic service. The app was designed and implemented to be easily accessible to ED physicians, regularly updated by academic residents on call, and a real-time source of the number of open AIM admission spots. We found a significant improvement in ED and AIM provider satisfaction with the admission process. There was also a significant increase in admissions to the AIM service after implementation of the app. We submit that the implementation of a mobile app is a viable, cost-efficient, and effective method to streamline the admission process from the ED to AIM services at community-based hospitals.

    The traditional Medicare program requires an enrollee to have a hospital stay of at least three consecutive calendar days to qualify for coverage of subsequent postacute care in a skilled nursing facility. This long-standing policy, implemented to discourage premature discharges from hospitals, might now be inappropriately lengthening hospital stays for patients who could be transferred sooner. To assess the implications of eliminating the three-day qualifying stay requirement, we compared hospital and postacute skilled nursing facility utilization among Medicare Advantage enrollees in matched plans that did or did not eliminate that requirement in 2006-10. Among hospitalized enrollees with a skilled nursing facility admission, the mean hospital length-of-stay declined from 6.9 days to 6.7 days for those no longer subject to the qualifying stay but increased from 6.1 to 6.6 days among those still subject to it, for a net decline of 0.7 day when the three-day stay requirement was eliminated. The elimination was not associated with more hospital or skilled nursing facility admissions or with longer lengths-of-stay in a skilled nursing facility. These findings suggest that eliminating the three-day stay requirement conferred savings on Medicare Advantage plans and that study of the requirement in traditional Medicare plans is warranted.

    Previous studies have shown an association between insurance status and use of resources for inpatient care. We sought to assess whether insurance status influences decisions regarding the evaluation and treatment of head injured patients in the emergency department (ED). Head injured patients were identified from ED data from 4 hospitals reporting to the Kentucky Emergency Medical Services Information System. Multiple regression analysis using admission, ED length of stay, and ED charges as outcome variables was then performed. From 216,137 ED visits there were 8,591 (4%) head injured patients identified from the database. Eliminating those with revisits, transfers to another hospital in the database, and isolated facial lacerations, there were 3,821 cases. Controlling for age, hospital, race, primary diagnosis, and indicators of severity of the injury, insurance status was significantly associated with hospital admission. Those uninsured were the least likely to be admitted (OR 0.41; 95% CI (0.31, 0.50), whereas those with public insurance had an intermediate probability (OR 0.50 95% CI (0.37, 0.68) as compared with those with private insurance. Similarly, ED charges were lower for Medicaid patients than insured patients ($880) and tended to be slightly lower for uninsured patients ($1,043) than insured patients ($1,141) (P =.001). Length of stay in the ED was shorter for publicly insured patients (179 minutes) than uninsured (186 minutes) and privately insured patients (192 minutes) (P =.001). The extent of evaluation and admission for head injured patients is associated with insurance status. This creates a dual standard of care for patients. Practitioners should work to standardize the evaluation of patients independent of paying status.

    Increasing numbers of dengue infection worldwide have led to a rise in deaths due to complications caused by this disease. We present here a cross-sectional study of dengue patients who attended the Emergency and Trauma Department of Ampang Hospital, one of Malaysia's leading specialist hospitals. The objective was to search for potential clustering of severe dengue, in space and/or time, among the annual admissions with the secondary objective to describe the spatio-temporal pattern of all dengue cases admitted to this hospital. The dengue status of the patients was confirmed serologically with the geographic location of the patients determined by residency, but not more specific than the street level. A total of 1165 dengue patients were included in the analysis using SaTScan software. The mean age of these patients was 27.8 years, with a standard deviation of 14.2 years and an age range from 1 to 77 years, among whom 54 (4.6%) were cases of severe dengue. A cluster of general dengue cases was identified occurring from October to December in the study year of 2015 but the inclusion of severe dengue in that cluster was not statistically significant (P=0.862). The standardized incidence ratio was 1.51. General presence of dengue cases was, however, detected to be concentrated at the end of the year, which should be useful for hospital planning and management if this pattern holds.

    Admission diagnosis represents the diagnosis of an illness, injury or condition due to which a patient is referred to hospital to be admitted. Discharge diagnosis represents the main reason of illness or condition due to which a patient is admitted. The aim of this study was to analyze the agreement between admission diagnostic groups and discharge diagnostic groups of patients in the Clinical Center Kragujevac in the period from January 1, 2006 to December 31, 2013 on the basis of the hospitalization report. From the basic set of reports, 5% of random samples were singled out and they contained 20,422 reports. Out of the given number of reports, 18,173 hospitalization reports were complete and then further analyzed in the paper. Admission diagnostic groups given by the primary care doctor were compared with discharge diagnostic groups filled out by the practicing physician in the hospital ward from which a patient was discharged. The agreement of these two diagnostic groups was an indication of the high-quality performance of the primary care doctor. Agreement analysis was conducted using Cohen’s Kappa statistics. Agreement analysis showed that the values of the Kappa coefficient for the five leading admission diagnostic groups were in the range of κ = 0.61 to κ = 0.94. The values of the Kappa coefficient for the five most common discharge diagnostic groups were in the range of κ = 0.55 to κ = 0.81. Hospitalization report is a reliable individual report on inpatient care, so it could be used in determining the degree of agreement between admission diagnostic groups and discharge diagnostic groups.

    Background: In children, community-acquired pneumonia is a frequent cause of emergency department (ED) presentation and hospital admission. Quality primary care may prevent some of these hospital visits. Aims: The aim of this study was to identify primary care factors associated with ED presentation and hospital admission of preschool-aged children with community-acquired pneumonia. Methods: A case–control study was conducted by enrolling three groups: children presenting to the ED with pneumonia and admitted (n=326), or discharged home (n=179), and well-neighbourhood controls (n=351). Interviews with parents and primary care staff were conducted and health record review was performed. The association of primary care factors with ED presentation and hospital admission, controlling for available confounding factors, was determined using logistic regression. Results: Children were more likely to present to the ED with pneumonia if they did not have a usual general practitioner (GP) (odds ratio (OR)=2.50, 95% confidence interval (CI)=1.67–3.70), their GP worked ⩽20 h/week (OR=1.86, 95% CI=1.10–3.13) or their GP practice lacked an immunisation recall system (OR=5.44, 95% CI=2.26–13.09). Lower parent ratings for continuity (OR=1.63, 95% CI=1.01–2.62), communication (OR=2.01, 95% CI=1.29–3.14) and overall satisfaction (OR=2.16, 95% CI=1.34–3.47) increased the likelihood of ED presentation. Children were more likely to be admitted when antibiotics were prescribed in primary care (OR=2.50, 95% CI=1.43–4.55). Hospital admission was less likely if children did not have a usual GP (OR=0.22, 95% CI=0.11–0.40) or self-referred to the ED (OR=0.48, 95% CI=0.26–0.89). Conclusions: Accessible and continuous primary care is associated with a decreased likelihood of preschool-aged children with pneumonia presenting to the ED and an increased likelihood of hospital admission, implying more appropriate referral. Lower parental satisfaction is associated with an

    In old subjects exposed to extreme high temperature during a heat wave, studies have consistently reported an excess of death from cardio- or cerebro-vascular disease. By contrast, dehydration, heat stroke, acute renal insufficiency, and respiratory disease were the main causes of hospital admission in the two studies carried out in elderly during short spells of hot weather. The excess of circulatory disease reported by mortality studies, but not by morbidity studies, could be explained by the hypothesis that deaths from circulatory disease occur rapidly in isolated people before they reach a hospital. Since the contrasting patterns of hospital admission and mortality during heat waves could also be due to chance (random variation over time and space in the spectrum of diseases induced by extreme heat), and bias (poor quality of diagnosis on death certificate and other artifacts), it should be confirmed by a concurrent study of mortality and morbidity. Many heat-related diseases may be preventable with adequate warning and an appropriate response to heat emergencies, but preventive efforts are complicated by the short time interval that may elapse between high temperatures and death. Therefore, prevention programs must be based around rapid identification of high-risk conditions and persons. The effectiveness of the intervention measures must be formally evaluated. If cardio- and cerebro-vascular diseases are rapidly fatal health outcomes with a short time interval between exposure to high temperature and death, deaths from circulatory disease might be an useful indicator in evaluating the effectiveness of a heat watch/warning system.

    The dangerousness of the mentally ill patient is still unknown. This study assesses the actual prevalence of violent and intimidating behaviours in psychiatric patients at the time of their admission, or in the days leading up to their admission to a Quebec hospital. These behaviours have been measured on a six-point scale whose reliability for this population is appropriate. The consecutive sample consists of 383 adult admissions, and the results show that 83.0 percent of the involuntary admissions and 40.7 percent of the voluntary admissions manifested violent or intimidating behaviours at the time of hospitalization. The results support the clinical experience that psychiatric patients often exhibit this type of behaviour on admission.

    Smoking restriction laws have spread worldwide during the last decade. Previous studies have shown a decline in the community rates of myocardial infarction after enactment of these laws. However, data are scarce about the Latin American population. In the first phase of this study, we reported the successful implementation of the law in São Paulo city, with a decrease in carbon monoxide rates in hospitality venues. To evaluate whether the 2009 implementation of a comprehensive smoking ban law in São Paulo city was associated with a reduction in rates of mortality and hospital admissions for myocardial infarction. We performed a time-series study of monthly rates of mortality and hospital admissions for acute myocardial infarction from January 2005 to December 2010. The data were derived from DATASUS, the primary public health information system available in Brazil and from Mortality Information System (SIM). Adjustments and analyses were performed using the Autoregressive Integrated Moving Average with exogenous variables (ARIMAX) method modelled by environmental variables and atmospheric pollutants to evaluate the effect of smoking ban law in mortality and hospital admission rate. We also used Interrupted Time Series Analysis (ITSA) to make a comparison between the period pre and post smoking ban law. We observed a reduction in mortality rate (-11.9% in the first 17 months after the law) and in hospital admission rate (-5.4% in the first 3 months after the law) for myocardial infarction after the implementation of the smoking ban law. Hospital admissions and mortality rate for myocardial infarction were reduced in the first months after the comprehensive smoking ban law was implemented.

    Abstract Background NSAIDs are a significant cause of drug-related hospital admissions and deaths. The therapeutic effects of NSAIDs have been associated with the risk for developing adverse events, mainly in the gastrointestinal tract. Objectives The focus of this study was to identify the most common risk factors associated with NSAID-induced upper gastrointestinal bleeding (UGIB) resulting in hospital admissions. A secondary end point was the relationship between use of gastroprotective treatment and relevant risk factors to NSAID-induced UGIB in the selected population. Methods This study was a cross-sectional, retrospective, case-series analysis of NSAID-induced UGIB resulting in hospital admission to the Requena General Hospital, Valencia, Spain, occurring from 1997 to 2005. International Classification of Diseases, Ninth Revision, Clinical Modification codes were used to identify UGIB admissions associated with NSAIDs. To estimate the probability of association between UGIB and the use of NSAIDs, the Naranjo adverse drug reaction probability was used. Patients were categorized as high-risk to develop UGIB if they met ≥1 of the following risk criteria (relevant risk factors): aged ≥65 years (age risk factor); peptic ulcer disease or NSAID gastropathy occurring in the year before their hospital admission (history risk factor); and concomitant use of other NSAIDs, systemic corticoids, oral anticoagulants, or platelet aggregation inhibitors (concomitant medication risk factor). Patients were categorized as candidates to use gastroprotections if they met ≥1 of the relevant risk factors. Patients were categorized as users of gastroprotective treatment if they used proton pump inhibitors, histamine H2-receptor antagonists, or misoprostol at hospital admission. Results This study comprised 209 cases of NSAID-induced UGIB (129 men, 80 women: mean [SD] age, 71.5 [13.8] years; 128 [61.2%] receiving acetyl salicylic acid [ASA], with 72 [34.4%] receiving low

    Little is known about the effect of preinjury residence on inpatient mortality following hip fracture. This study addressed whether (1) admission from a nursing home residence and (2) admission from another hospital were associated with higher inpatient mortality after a hip fracture. Using the National Hospital Discharge Survey database, we analyzed an estimated 2 124 388 hip fractures discharges, from 2001 to 2007. Multivariable logistic regression analysis was performed to identify whether admission from a nursing home and admission from another hospital were independent risk factors for inpatient mortality. Our primary null hypothesis is that there is no difference in inpatient mortality rates after hip fracture in patients admitted from a nursing home, compared to other forms of admission. The secondary null hypothesis is that there is no difference in inpatient mortality after hip fracture in patients whose source of admission was another hospital, compared to other sources of admission. Almost 4% of the patients were admitted from a nursing home and 6% from another hospital. The mean age was 79 years and 71% were women. The majority of patients were treated with internal fixation. Admission from a nursing home residence (odds ratio [OR] of 2.1, confidence interval [CI] 1.9-2.3) and prior hospital stay (OR 3.4, CI 3.2-3.7) were associated with a higher risk of inpatient mortality after accounting for other comorbidities and type of treatment. Patients transferred to an acute care hospital from a long-term care facility or another acute care hospital are at particularly high risk of inpatient death. This subset of patients should be considered separately from patients admitted from other sources. Prognostic level II.

    Providers and patients bring different understandings of health and disease to their encounters in the hospital setting. The literature to date only infrequently addresses patient and provider concordance on the reported reason for hospitalization, that is, whether they express this reason in similar ways. An agreement or common ground between such understandings can serve as a basis for future communication regarding an illness and its treatment. We interviewed a convenience sample of patients on the medical wards of an urban academic medical center. We asked subjects to state the reason why their doctors admitted them to the hospital, and then compared their statement with the reason in the medical record. We defined concordance on reported reason for hospitalization as agreement between the patient's report and the reason abstracted from the chart. We interviewed and abstracted chart data from a total of 46 subjects. Concordance on reported reason for hospitalization was present in 24 (52%) and discordance in 17 (37%); 5 patients (11%) could not give any reason for their hospitalization. Among the 17 patients whose report was discordant with their chart, 12 (71%) reported a different organ system than was recorded in the chart. A significant proportion of medical inpatients could not state their physicians' reason for admission. In addition, patients who identify a different reason for hospitalization than the chart often give a different organ system altogether. Providers should explore patient understanding of the reason for their hospitalization to facilitate communication and shared decision making.

    The subject of sex and gender differences is relevant to the study of health effects of environmental exposures. In this study the authors aim at assessing the differences that may exist between males and females regarding short-term air pollution health effects. They studied the short-term relationships between air pollution levels and respiratory hospital admissions in greater Paris area for patients older than 15 years between 2000 and 2003. They also conducted time series analyses by using generalized additive models. For an increase of 10 microg/m3 in the air pollutant levels, the increase in relative risk of hospitalization was higher for males than for females and was significant only for males. These differences may not result solely from differences in biological susceptibility to air pollution because other factors related to gender (differences in individual exposures, in health care management, and so on) may play a role.

    Objective To evaluate if observed increased weekend mortality was associated with poorer quality of care for patients admitted to hospital with chronic obstructive pulmonary disease (COPD) exacerbation. Design Prospective case ascertainment cohort study. Setting 199 acute hospitals in England and Wales, UK. Participants Consecutive COPD admissions, excluding subsequent readmissions, from 1 February to 30 April 2014 of whom 13 414 cases were entered into the study. Main outcomes Process of care mapped to the National Institute for Health and Care Excellence clinical quality standards, access to specialist respiratory teams and facilities, mortality and length of stay, related to time and day of the week of admission. Results Mortality was higher for weekend admissions (unadjusted OR 1.20, 95% CI 1.00 to 1.43), and for case-mix adjusted weekend mortality when calculated for admissions Friday morning through to Monday night (adjusted OR 1.19, 95% CI 1.00 to 1.43). Median time to death was 6 days. Some clinical processes were poorer on Mondays and during normal working hours but not weekends or out of hours. Specialist respiratory care was less available and less prompt for Friday and Saturday admissions. Admission to a specialist ward or high dependency unit was less likely on a Saturday or Sunday. Conclusions Increased mortality observed in weekend admissions is not easily explained by deficiencies in early clinical guideline care. Further study of out-of-hospital factors, specialty care and deaths later in the admission are required if effective interventions are to be made to reduce variation by day of the week of admission.

    2010-01-01

    Background Adverse drug reactions (ADR) are a substantial cause of hospital admissions. We conducted a nationwide study to estimate the burden of hospital admissions for ADRs in Spain during a six-year period (2001-2006) along with the associated total health cost. Methods Data were obtained from the national surveillance system for hospital data (Minimum Basic Data Set) maintained by the Ministry of Health and Consumer Affairs, and covering more than 95% of Spanish hospitals. From these admissions we selected all hospitalization that were code as drug-related (ICD-9-CM codes E), but intended forms of overdoses, errors in administration and therapeutics failure were excluded. The average number of hospitalizations per year, annual incidence of hospital admissions, average length of stay in the hospital, and case-fatality rate, were calculated. Results During the 2001-2006 periods, the total number of hospitalized patients with ADR diagnosis was 350,835 subjects, 1.69% of all acute hospital admissions in Spain. The estimated incidence of admissions due to ADR decreased during the period 2001-2006 (p < 0.05). More than five percent of patients (n = 19,734) died during an ADR-related hospitalization. The drugs most commonly associated with ADR-related hospitalization were antineoplastic and immunosuppressive drugs (n = 75,760), adrenal cortical steroids (n = 47,539), anticoagulants (n = 26,546) and antibiotics (n = 22,144). The costs generated by patients in our study increased by 19.05% between 2001 and 2006. Conclusions Approximately 1.69% of all acute hospital admissions were associated with ADRs. The rates were much higher for elderly patients. The total cost of ADR-related hospitalization to the Spanish health system is high and has increased between 2001 and 2006. ADRs are an important cause of admission, resulting in considerable use of national health system beds and a significant number of deaths. PMID:20942906

    In December 1968 an emergency service was begun in Edinburgh to expedite admission to hospital of patients with severe acute asthma. During the first 10 years requests were made to admit 112 patients to a respiratory unit with provision for intensive care on 360 occasions. Four of the patients died of their disease, one in hospital and three before admission. It was thought that the death rate would have been much higher had conventional admission procedures been observed. Owing to ethical objections to a controlled trial it was not possible to obtain substantive proof that the service reduced deaths from asthma. Nevertheless, there was strong circumstantial evidence that organised facilities for the immediate admission to hospital of patients with a history of life-threatening attacks would result in fewer deaths at home. Earlier admission also apparently reduced hospital mortality and the number of patients requiring tracheal intubation and mechanical ventilation. It is concluded that there is a prima facie case for an emergency asthma admission serivce similar to that operating in Edinburgh to be established in all cities and large towns. PMID:519358

    Crimean-Congo hemorrhagic fever (CCHF) has been reported from all provinces of Pakistan. Little is known about the seasonal variations in the disease and its association with weather conditions. In this study, we explored time-series data about monthly number of CCHF admissions (2007-2010) in three public sector hospitals of Quetta-the capital city of Baluchistan province of Pakistan. Cosinor analysis was carried out to investigate seasonality in the data. To assess the effect of average monthly ambient temperature (°C) on disease, a distributed lag nonlinear model (DLNM) was applied. Cosinor model revealed statistically significant seasonality in monthly number of CCHF patients admitted to the study hospitals. The estimated amplitude was 3.24 cases per month with phase in mid-June and low point in mid-December. DLNM confirmed nonlinear and delayed effect of temperature on hospital admissions. At a lag of 2 months, the cumulative relative risk was more than 1 at temperature at 18.37 °C and above. In addition, relative risk was significantly high at 60th (21.98 °C), 70th (24.50 °C), 80th (27.33 °C), and 90th (29.25 °C) percentiles of temperature (relative to median value, 18.37 °C). Inclusion of Eid-al-Adha as a predictor did not improve the fitness of DLNM. Based on our analysis, we concluded significant seasonality in CCHF hospital admissions. Our findings also suggested average monthly ambient temperature (°C) as a significant predictor of CCHF hospitalizations. DLNM presented in this study may be improved with inclusion of other possible time-varying predictors particularly meteorological conditions of this region.

    Electroconvulsive therapy (ECT) is a highly effective treatment for patients with severe mental illness (SMI). Maintenance ECT (M-ECT) is required for many elderly patients experiencing severe recurrent forms of mood disorders, whereas M-ECT for schizophrenia patients is a poorly studied treatment. We report on the outcomes in aged patients with SMI: schizophrenia and severe affective disorders treated by M-ECT of varying duration to prevent relapse after a successful course of acute ECT. The study measured the effectiveness of M-ECT in preventing hospital readmissions and reducing admission days. A retrospective chart review of 42 consecutive patients comparing the number and length of psychiatric admissions before and after the start of M-ECT was used. We analyzed diagnoses, previous ECT treatments, number of ECT treatments, and number and length of psychiatric admissions before and after M-ECT. Mean age in our sample was 71.5 (6.9) years. Twenty-two (52%) patients experienced severe affective disorders and 20 (48%) experienced schizophrenia. Patients were administered 92.8 (85.9) M-ECT treatments. Average duration of the M-ECT course was 34 (29.8) months. There were on average 1.88 admissions before M-ECT and only 0.38 admissions in the M-ECT period (P < 0.001). Duration of mean hospitalization stay decreased from 215.9 to 12.4 days during the M-ECT (P < 0.01). Our findings suggest that acute ECT followed by M-ECT is highly effective in selected elderly patients with SMIs.

    Particulate matter with a diameter below 10 µ (PM10) has been a major concern in the Tamar Valley, Launceston, where wood heaters are extensively used. We examined the relationship between PM10 levels, meteorological variables, respiratory medications and hospital admissions for respiratory disease over the decade 1992-2002. PM10 levels were provided by the Department of Primary Industry Water, Parks and Environment, and meteorological variables from the Bureau of Meteorology. We obtained hospital discharge codes for the Launceston General Hospital. Poisson regression was used for statistical analyses. Mean daily PM10 levels declined from 50.7 to 16.5 μg/m(3). Hospitalisations for asthma decreased from 29 to 21 per month, whereas chronic obstructive pulmonary disease (COPD) increased and bronchitis/bronchiolitis remained unchanged. We found a 10 μg/m(3) increase in PM10 to be associated with a 4% increase in admissions for acute bronchitis/bronchiolitis (p0.05), but no association with asthma or COPD was found. All respiratory diseases showed seasonal patterns of hospitalisation. This is the first long-term study in Australia to demonstrate an association between PM10 levels and respiratory diseases. Reducing exposure to PM10 may decrease hospital admissions for respiratory diseases. Better preventive measures, including sustained public health initiatives to combat air pollution, are required to reduce respiratory morbidity.

    Epilepsy affects approximately 1% of the population in the United States with frequent hospital admissions accounting for a significant burden on patients and society as a whole. Weekend admissions have generally been found to have poorer outcomes compared to weekday admissions with increased rates of preventable complications, such as nationally identified "hospital-acquired conditions" (HAC). This study aimed to assess the impact of weekend admission on HACs and mortality in the adult epilepsy population. All adult patients with epilepsy hospitalized in the U.S. from 2000 to 2010 in the Nationwide Inpatient Sample. There were 12,997,181 admissions for epilepsy with 10,106,152 (78%) weekday, 2,891,019 (22%) weekend, and 10 (<0.1%) missing admissions. Weekend admissions saw a 10% increased likelihood of both HACs (RR=1.10, 95% CI:1.09, 1.11, p<0.01) and mortality (RR=1.10, 95% CI: 1.09, 1.11, p<0.01) compared to weekday admissions. The occurrence of HAC was associated with higher inpatient charges (RR=1.36, 95% CI: 1.35, 1.36, p<0.01), pLOS (RR=1.21, 95% CI: 1.21, 1.22, p<0.01), and higher mortality (RR=1.13, 95% CI: 1.12, 1.14, p<0.01). Prior studies have shown weekend admissions are usually associated with higher rates of complications leading to higher costs and a longer hospital stay. Likewise, weekend admissions for epilepsy were associated with increased rates of HACs and mortality; however, they were also negatively associated with LOS and total charge. Thus, weekend admissions for epilepsy should be considered high risk with greater effort made to mitigate these risks. Copyright © 2017 Elsevier Inc. All rights reserved.

    A retrospective analysis of the surveillance data on laboratory confirmed cases of influenza in 4 post pandemic seasons in Serbia was performed to evaluate predictors of hospitalization and admission to intensive care units (ICU). The specimens, including nasal and throat swabs were tested for influenza. Univariate and multivariate logistic regression analyses were performed. Data of a total of 777 confirmed influenza cases were analyzed. Age > 65 years, the presence of any co-morbidity or the presence of ≥ 2 comorbidities, infection with influenza virus subtype A (H1) pdm09, and an interval greater than 3 days between symptom onset and the first physician visit, were independently associated with hospital admission. These variables, as well as infection with non-subtype influenza virus A, were predictors for ICU admission. Obesity and chronic neurological disease were independent predictors for ICU admission but not hospitalization. Overall, 41.7% of patients with influenza had at least one co-morbidity, but only 3% of all patients were vaccinated against influenza. Identification of high risk groups and education of these groups regarding their increased susceptibility to severe forms of influenza, and in particular regarding the importance of influenza vaccination, is essential.

    Although there is growing evidence linking chronic obstructive pulmonary disease (COPD) hospital admissions to the exposure to ambient air pollution, the effect can vary depending on the local geography, pollution type, and pollution level. The number of large-scale multicity studies remains limited in China. This study aims to assess the short-term effects of ambient air pollution (PM 2.5 , PM 10 , SO₂, NO₂) on chronic obstructive pulmonary disease hospital admissions from 2015 to 2016, with a total of 216,159 records collected from 207 hospitals in 17 cities all over the Shandong province, east China. Generalized additive models and penalized splines were applied to study the data whilst controlling for confounding meteorological factors and long-term trends. The air pollution was analyzed with 0–6 day lag effects and the percentage change of hospital admissions was assessed for a 10-μg/m³ increase in the air pollution levels. We also examined the percentage changes for different age groups and gender, respectively. The results showed that air pollution was significantly associated with adverse health outcomes and stronger effects were observed for females. The air pollution health effects were also impacted by geographical factors such that the air pollution had weaker health effects in coastal cities.

    Limited data are available describing the clinical presentation and risk factors for admission to the intensive care unit for children with 2009 H1N1 infection. We conducted a retrospective chart review of all hospitalized children with 2009 influenza A (H1N1) and 2008-09 seasonal influenza at The Children's Hospital, Denver, Colorado. Of the 307 children identified with 2009 H1N1 infections, the median age was 6 years, 61% were male, and 66% had underlying medical conditions. Eighty children (26%) were admitted to the ICU. Thirty-two (40%) of the ICU patients required intubation and 17 (53%) of the intubated patients developed acute respiratory distress syndrome (ARDS). Four patients required extracorporeal membrane oxygenation. Eight (3%) of the hospitalized children died. Admission to the ICU was significantly associated with older age and underlying neurological condition. Compared to the 90 children admitted during the 2008-09 season, children admitted with 2009 H1N1 influenza were significantly older, had a shorter length of hospitalization, more use of antivirals, and a higher incidence of ARDS. Compared to the 2008-09 season, hospitalized children with 2009 H1N1 influenza were much older and had more severe respiratory disease. Among children hospitalized with 2009 H1N1 influenza, risk factors for admission to the ICU included older age and having an underlying neurological condition. Children under the age of 2 hospitalized with 2009 H1N1 influenza were significantly less likely to require ICU care compared to older hospitalized children.

    The outcome of high risk pregnancies is better in tertiary hospitals. The German government introduced levels of perinatal care only in 2006. The aim of this study was to investigate how many children are to be expected for each level, taking the possible width of interpretation of the admission criteria into account. Perinatal quality assurance data from four German states (2005) were available. Based on the admission criteria used for level definitions, children were categorised into four different levels of care. To illustrate the possible width of interpretation of these admission criteria three analytical strategies were used. In addition, the distribution of children on different types of hospitals prior to the introduction of levels of care was analysed. Most deliveries (86-93 %) correspond to the lowest level, and only 1-5 % to the highest. Up to 15 % of children who should have been cared for in the highest level were born in hospitals with less than 500 annual deliveries. Among the neonates with risk profiles corresponding to the admission criteria for the two highest levels, up to 30 % were born in delivery units without NICUs. The majority (83 %) of attached NICUs had low caseloads (< 50 neonates < 1500 g / year). Most children fulfil the admission criteria for the lowest level of care whereas the need for specialised centres is rather low. Optimising the place of birth appropriately remains a challenge. Definition of levels of care based on admission criteria are difficult to implement due to a broad variety of interpretations.

    To investigate whether exposure to aircraft noise increases the risk of hospitalization for cardiovascular diseases in older people (≥ 65 years) residing near airports. Multi-airport retrospective study of approximately 6 million older people residing near airports in the United States. We superimposed contours of aircraft noise levels (in decibels, dB) for 89 airports for 2009 provided by the US Federal Aviation Administration on census block resolution population data to construct two exposure metrics applicable to zip code resolution health insurance data: population weighted noise within each zip code, and 90th centile of noise among populated census blocks within each zip code. 2218 zip codes surrounding 89 airports in the contiguous states. 6 027 363 people eligible to participate in the national medical insurance (Medicare) program (aged ≥ 65 years) residing near airports in 2009. Percentage increase in the hospitalization admission rate for cardiovascular disease associated with a 10 dB increase in aircraft noise, for each airport and on average across airports adjusted by individual level characteristics (age, sex, race), zip code level socioeconomic status and demographics, zip code level air pollution (fine particulate matter and ozone), and roadway density. Averaged across all airports and using the 90th centile noise exposure metric, a zip code with 10 dB higher noise exposure had a 3.5% higher (95% confidence interval 0.2% to 7.0%) cardiovascular hospital admission rate, after controlling for covariates. Despite limitations related to potential misclassification of exposure, we found a statistically significant association between exposure to aircraft noise and risk of hospitalization for cardiovascular diseases among older people living near airports.

    Background The objective of this study was to evaluate the factors predictive of 28-day mortality and admission to Intensive Care Unit (ICU) in patients with ANCA-related pulmonary vasculitis. Methods We reviewed the medical records and imaging studies of 65 patients diagnosed with ANCA-related vasculitis hospitalized with pulmonary complications between February 1985 and November 2002. All patients underwent open or video-assisted thoracoscopic lung biopsy, had a positive ANCA serology, and were negative for glomerular basement membrane antibodies. Results At presentation, 72% had dyspnea, 68% fever, 47% cough, 45% elevated blood pressure, 32.3% hemoptysis, 26.1% sinus involvement, 15% renal failure, and 4.6% scleritis. Pathological findings included alveolar hemorrhage (60%), granulomatous inflammation (46%), and capillaritis (38%). A significant number required mechanical ventilation (27.7%), hemodialysis (24.6%), continuous renal replacement therapy (3.1%), and plasmapheresis (3.1%). The 28-day mortality was 16.9% (11/65). Mechanical ventilation (OR 68, P < 0.005), admission to ICU (OR 18.5, P < 0.01), and blood transfusion (OR 22.4, P < 0.004) were strong predictors of increased mortality within 28 days after admission. Respiratory failure (OR 31, P < 0.0007), hemoptysis (OR 2.9, P < 0.06), smoking (OR 5.9, P < 0.02), and acute renal failure (OR 7.8, P < 0.01) were also predictors for admission to the ICU. Conclusion In patients with ANCA-related pulmonary vasculitis several clinical factors, but not pathologic findings or ANCA titers, are associated with ICU admission and/or 28-day mortality.

    Short-term exposure to NO₂ has been associated with adverse health effects and there is increasing concern that NO₂ is causally related to health effects, not merely a marker of traffic-generated pollution. No comprehensive meta-analysis of the time-series evidence on NO₂ has been published since 2007. To quantitatively assess the evidence from epidemiological time-series studies published worldwide to determine whether and to what extent short-term exposure to NO₂ is associated with increased numbers of daily deaths and hospital admissions. We conducted a quantitative systematic review of 204 time-series studies of NO₂ and daily mortality and hospital admissions for several diagnoses and ages, which were indexed in three bibliographic databases up to May 2011. We calculated random-effects estimates by different geographic regions and globally, and also tested for heterogeneity and small study bias. Sufficient estimates for meta-analysis were available for 43 cause-specific and age-specific combinations of mortality or hospital admissions (25 for 24 h NO₂ and 18 of the same combinations for 1 h measures). For the all-age group, a 10 µg/m(3) increase in 24 h NO₂ was associated with increases in all-cause, cardiovascular and respiratory mortality (0.71% (95% CI 0.43% to 1.00%), 0.88% (0.63% to 1.13%) and 1.09% (0.75% to 1.42%), respectively), and with hospital admissions for respiratory (0.57% (0.33% to 0.82%)) and cardiovascular (0.66% (0.32% to 1.01%)) diseases. Evidence of heterogeneity between geographical region-specific estimates was identified in more than half of the combinations analysed. Our review provides clear evidence of health effects associated with short-term exposure to NO₂ although further work is required to understand reasons for the regional heterogeneity observed. The growing literature, incorporating large multicentre studies and new evidence from less well-studied regions of the world, supports further quantitative

    The need for surgery can be a decisive factor for long-term smoking cessation. On the other hand, situations that precipitate stress could precipitate smoking relapse. The authors decided to study the impact of a surgery on the patient's effort to cease smoking for, at least, 24h before hospital admission and possible relapse on the last 24h before hospital admission for ex-smokers. Smoker, ex-smokers and non-smokers adults, either from pre-anesthetic clinic or recently hospital admitted for scheduled elective surgeries that were, at most, 6h inside the hospital buildings were included in the study. The patients answered a questionnaire at the ward or at the entrance of the operating room (Admitted group) or at the beginning of the first pre-anesthetic consultation (Clinic group) and performed CO measurements. 241 patients were included, being 52 ex-smokers and 109 never smokers and 80 non-smokers. Smokers had higher levels of expired carbon monoxide than non-smokers and ex-smokers (9.97±6.50 vs. 2.26±1.65 vs. 2.98±2.69; p=0.02). Among the smokers, the Clinic group had CO levels not statistically different of those on the Admitted group (10.93±7.5 vs. 8.65±4.56; p=0.21). The ex-smokers presented with no significant differences for the carbon monoxide levels between the Clinic and Admitted groups (2.9±2.3 vs. 2.82±2.15; p=0.45). A medical condition, such as a surgery, without proper assistance is unlikely to be enough for a patient to stop smoking for, at least, 24h prior to admission. The proximity of a surgery was not associated with smoking relapse 24h before the procedure. Copyright © 2018. Publicado por Elsevier Editora Ltda.

    This study determined trends in hospital admission for diabetic ketoacidosis (DKA) in adults with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) from 1998 to 2013 in England. The study population included 23,246 adults with T1DM and 241,441 adults with T2DM from the Clinical Practice Research Datalink and Hospital Episode Statistics. All hospital admissions for DKA as the primary diagnosis from 1998 to 2013 were identified. Trends in hospital admission for DKA in incidence, length of hospital stay, 30-day all-cause readmission rate, and 30-day and 1-year all-cause mortality rates were determined using joinpoint regression, negative binomial regression, and logistic regression models. For T1DM, the incidence of hospital admission for DKA increased between 1998 and 2007 and remained static until 2013. The incidence in 2013 was higher than that in 1998 (incidence rate ratio 1.53 [95% CI 1.09-2.16]). For T2DM, the incidence increased 4.24% (2.82-5.69) annually between 1998 and 2013. The length of hospital stay decreased over time for both diabetes types ( P ≤ 0.0004). Adults with T1DM were more likely to be discharged within 2 days compared with adults with T2DM (odds ratio [OR] 1.28 [1.07-1.53]). The 30-day readmission rate was higher in T1DM than in T2DM (OR 1.61 [1.04-2.50]) but remained unchanged for both diabetes types over time. Trends in 30-day and 1-year all-cause mortality rates were also stable, with no difference by diabetes type. In the previous 2 decades in England, hospitalization for DKA increased in adults with T1DM and in those with T2DM, and associated health care performance did not improve except decreased length of hospital stay. © 2018 by the American Diabetes Association.

    The quality of care delivered and clinical outcomes of care are of paramount importance. Wide variations in the outcome of emergency care have been suggested, but the scale of variation, and the way in which outcomes are inter-related are poorly defined and are critical to understand how best to improve services. This study quantifies the scale of variation in three outcomes for a contemporary cohort of patients undergoing emergency medical and surgical admissions. The way in which the outcomes of different diagnoses relate to each other is investigated. A retrospective study using the English Hospital Episode Statistics 2005-2010 with one-year follow-up for all patients with one of 20 of the commonest and highest-risk emergency medical or surgical conditions. The primary outcome was in-hospital all-cause risk-standardised mortality rate (in-RSMR). Secondary outcomes were 1-year all-cause risk-standardised mortality rate (1 yr-RSMR) and 28-day all-cause emergency readmission rate (RSRR). 2,406,709 adult patients underwent emergency medical or surgical admissions in the groups of interest. Clinically and statistically significant variations in outcome were observed between providers for all three outcomes (p < 0.001). For some diagnoses including heart failure, acute myocardial infarction, stroke and fractured neck of femur, more than 20% of hospitals lay above the upper 95% control limit and were statistical outliers. The risk-standardised outcomes within a given hospital for an individual diagnostic group were significantly associated with the aggregated outcome of the other clinical groups. Hospital-level risk-standardised outcomes for emergency admissions across a range of specialties vary considerably and cross traditional speciality boundaries. This suggests that global institutional infra-structure and processes of care influence outcomes. The implications are far reaching, both in terms of investigating performance at individual hospitals and in

    Timely presentation to care for people newly diagnosed with HIV is critical to optimize health outcomes and reduce onward HIV transmission. Studies describing presentation to care following diagnosis during a hospital admission are lacking. We sought to assess the timeliness of presentation to care and to identify factors associated with delayed presentation. We conducted a population-level study using health administrative databases. Participants were all individuals older than 16 and newly diagnosed with HIV during hospital admission in Ontario, Canada, between April 1, 2007 and March 31, 2015. We used modified Poisson regression models to derive relative risk ratios for the association between sociodemographic and clinical variables and the presentation to out-patient HIV care by 90 days following hospital discharge. Among 372 patients who received a primary HIV diagnosis in hospital, 83.6% presented to care by 90 days. Following multivariable analysis, we did not find associations between patient sociodemographic or clinical characteristics and presentation to care by 90 days. In a secondary analysis of 483 patients diagnosed during hospitalization but for whom HIV was not recorded as the principal reason for admission, 73.1% presented to care by 90 days. Following multivariable adjustment, we found immigrants from countries with generalized HIV epidemics (RR 1.265, 95% CI 1.133-1.413) were more likely to present to care, whereas timely presentation was less likely for people with a mental health diagnosis (RR 0.817, 95% CI 0.742-0.898) and women (RR 0.748, 95% CI 0.559-1.001). Future work should evaluate mechanisms to facilitate presentation to care among these populations.

    The health gap between Indigenous and non-Indigenous Australians may be exacerbated by climate change if temperature extremes have disproportionate adverse effects on Indigenous people. To explore this issue, we analysed the effect of temperature extremes on hospital admissions for respiratory diseases, stratified by age, Indigenous status and sex, for people living in two different climates zones in the Northern Territory during the period 1993–2011. We examined admissions for both acute and chronic respiratory diagnoses, controlling for day of the week and seasonality variables. Our analysis showed that: (1) overall, Indigenous hospital admission rates far exceeded non-Indigenous admission rates for acute and chronic diagnoses, and Top End climate zone admission rates exceeded Central Australia climate zone admission rates; (2) extreme cold and hot temperatures were associated with inconsistent changes in admission rates for acute respiratory disease in Indigenous and non-Indigenous children and older adults; and (3) no response to cold or hot temperature extremes was found for chronic respiratory diagnoses. These findings support our two hypotheses, that extreme hot and cold temperatures have a different effect on hospitalisations for respiratory disease between Indigenous and non-Indigenous people, and that these health risks vary between the different climate zones. We did not, however, find that there were differing responses to temperature extremes in the two populations, suggesting that any increased vulnerability to climate change in the Indigenous population of the Northern Territory arises from an increased underlying risk to respiratory disease and an already greater existing health burden.

    Reduced gestational age and low birthweight are associated with an increased risk of neonatal infections. However, the long-term risk of infection, especially in late preterm infants or those at near-normal birthweight, is unknown. We estimated whether rates of infection-related admissions to hospital for children in Western Australia were associated with age, gestational age, birthweight, and birth length. We did a population-based, data-linkage study using total-linked, registry data from the Western Australia Birth Register of all liveborn, non-Indigenous Australian singleton births recorded from Jan 1, 1980, to Dec 31, 2010. We followed up individuals from birth-related hospital discharge to age 18 years, death, or end of 2010, and linked to data about subsequent admissions to hospital or death registrations. Gestational age was assessed from both the last menstrual period and from estimates based on ultrasonography. We categorised birthweight by 500 g bands and birth length by 5 cm bands, and approximated the reference ranges for both to the 50th percentile. Because size at birth and gestational age are strongly associated, we calculated Z scores for gestational-specific and sex-specific birthweight, birth length, and ponderal index. Our primary outcomes were the number and type of infection-related admissions to hospital. We used multilevel negative binomial regression to generate rate ratios (RR) for such admissions, identified by codes from the International Classification of Diseases, versions 9 and 10-AM. We adjusted the RRs for maternal age at delivery, birth year, birth season, parity, sex, 5-min Apgar score, delivery method, socioeconomic status, and bronchopulmonary dysplasia. Of 719 311 liveborn singletons included in the analysis and followed up for 8 824 093 person-years, 365 867 infection-related admissions to hospital occurred for 213 683 (30%) children. Of the 719 311 children included in the analysis, 137 124 (19%) had one

    Currently, limited long-term data on hyperglycaemia and insulin sensitivity in burn patients are available and the data that do exist are primarily related to paediatric severe burns. The aim of this study was to assess if burn is associated with increased post-burn admissions for diabetes mellitus. A population-based longitudinal study using linked hospital morbidity and death data from Western Australia was undertaken of all persons hospitalized for a first burn (n=30,997) in 1980-2012 and a frequency matched non-injury comparison cohort, randomly selected from Western Australia's birth registrations and electoral roll (n=123,399). Crude admission rates and summed length of stay for diabetes mellitus were calculated. Negative binomial and Cox proportional hazards regression modelling were used to generate incidence rate ratios (IRR) and hazard ratios (HR), respectively. After adjustment for socio-demographic factors and pre-existing health status, the burn cohort had 2.21 times (95% Confidence Interval (CI): 1.36-1.56) as many admissions and almost three times the number of days in hospital with a diabetes mellitus diagnosis (IRR, 95% CI: 2.94, 2.12-4.09) than the uninjured cohort. Admission rates were significantly elevated for those burned during childhood (<18 years, IRR, 95% CI: 2.65, 1.41-4.97) and adulthood (≥18 years, IRR, 95% CI: 2.12, 1.76-2.55). Incident admissions were significantly elevated in the burn cohort during the first 5 years post-burn when compared with the uninjured (HR, 95% CI: 1.96, 1.46-2.64); no significant difference was found beyond 5 years post-burn (HR, 95% CI: 1.08, 0.82-1.41). Findings of increased hospital admission rates and prolonged length of hospital stay for diabetes mellitus in the burn cohort provide evidence that burns have longer term effects on blood glucose and insulin regulation after wound healing. The first five years after burn discharge appears to be a critical period with significantly elevated incident

    To compare baseline characteristics and those found during hospitalisation as predictors of functional decline at discharge (FDd) in elderly patients hospitalised due to acute illness. A review was made of the computerized records of patients admitted to a Geriatric Acute Unit of a tertiary hospital over a 10 year period. A record was made of demographic, clinical, functional and health-care variables. Functional decline at discharge (FDd) was defined by the difference between the previous Barthel Index (pBI) and the discharge Barthel Index (dBI). The percentage of FDd (%FDd=(pBI-dBI/pBI)×100) was calculated. The variables associated with greater %FDd in the bivariate analysis were included in multivariate logistic regression models. The predictive capacity of each model was assessed using the area under the ROC curve. The factors associated with greater %FDd were advanced age, female gender, to live in a nursing home, cognitive impairment, better baseline functional status and worse functional status at admission, number of diagnoses, and prolonged stay. The area under the ROC curve for the predictive models of %FDd was 0.638 (95% CI: 0.615-0.662) based on the previous situation, 0.756 (95% CI: 0.736-0.776) based on the situation during admission, and 0.952 (95% CI: 0.944-0.959) based on a combination of these factors. The overall assessment of patient characteristics, both during admission and baseline, may have greater value in prediction of FDd than analysis of factors separately in elderly patients hospitalised due to acute illness.

    To evaluate if observed increased weekend mortality was associated with poorer quality of care for patients admitted to hospital with chronic obstructive pulmonary disease (COPD) exacerbation. Prospective case ascertainment cohort study. 199 acute hospitals in England and Wales, UK. Consecutive COPD admissions, excluding subsequent readmissions, from 1 February to 30 April 2014 of whom 13 414 cases were entered into the study. Process of care mapped to the National Institute for Health and Care Excellence clinical quality standards, access to specialist respiratory teams and facilities, mortality and length of stay, related to time and day of the week of admission. Mortality was higher for weekend admissions (unadjusted OR 1.20, 95% CI 1.00 to 1.43), and for case-mix adjusted weekend mortality when calculated for admissions Friday morning through to Monday night (adjusted OR 1.19, 95% CI 1.00 to 1.43). Median time to death was 6 days. Some clinical processes were poorer on Mondays and during normal working hours but not weekends or out of hours. Specialist respiratory care was less available and less prompt for Friday and Saturday admissions. Admission to a specialist ward or high dependency unit was less likely on a Saturday or Sunday. Increased mortality observed in weekend admissions is not easily explained by deficiencies in early clinical guideline care. Further study of out-of-hospital factors, specialty care and deaths later in the admission are required if effective interventions are to be made to reduce variation by day of the week of admission. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Observational studies and trials from low-income countries indicate that measles vaccine has beneficial nonspecific effects, protecting against non-measles-related mortality. It is not known whether measles vaccine protects against hospital admissions. Between 2003 and 2007, 6417 children who had received the third dose of diphtheria, tetanus, and pertussis vaccine were randomly assigned to receive measles vaccine at 4.5 months or no measles vaccine; all children were offered measles vaccine at 9 months of age. Using hospital admission data from the national pediatric ward in Bissau, Guinea-Bissau, we compared admission rates between enrollment and the 9-month vaccination in Cox models, providing admission hazard rate ratios (HRRs) for measles vaccine versus no measles vaccine. All analyses were conducted stratified by sex and reception of neonatal vitamin A supplementation (NVAS). Before enrollment the 2 groups had similar admission rates. Following enrollment, the measles vaccine group had an admission HRR of 0.70 (95% confidence interval [CI], .52-.95), with a ratio of 0.53 (95% CI, .32-.86) for girls and 0.86 (95% CI, .58-1.26) for boys. For children who had not received NVAS, the admission HRR was 0.53 (95% CI, .34-.84), with an effect of 0.30 (95% CI, .13-.70) for girls and 0.73 (95% CI, .42-1.28) for boys (P = .08, interaction test). The reduction in admissions was separately significant for measles infection (admission HRR, 0 [95% CI, 0-.24]) and respiratory infections (admission HRR, 0.37 [95% CI, .16-.89]). Early measles vaccine may have major benefits for infant morbidity patterns and healthcare costs. Clinical trials registration NCT00168558.

    To investigate trend and seasonal pattern of occurrence and mortality of motorcycle accidents in patients referred to hospitals of Isfahan. This cross-sectional study was carried out using traffic accidents data of Isfahan province, extracted from Ministry of Health (MOH) database from 2006 to 2010. During the study period, 83648 people injured due to motorcycle traffic accidents were referred to hospitals, all of them entered in the study. Logistic regression model was used to calculate the hospital mortality odds ratio, and Cochrane-Armitage test was used for assessment of linear trend. During the study period, the hospital admission for motorcycle accident was 83,648 and 89.3% (74743) of them were men. Mean age in accidents time was 26.41±14.3 years. The injuries and death sex ratio were 8.4 and 16.9, respectively. Lowest admission rate was during autumn and highest during summer. The injury mortality odds ratio was 1.01 (CI 95% 0.73-1.39) in the Spring, 1.34 (CI95% 1.01-1.79) in summer and 1.17 (CI95% 0.83-1.63). It was also calculated to be 2.51 (CI95% 1.36-4.64) in age group 40-49, 2.39 (CI95% 1.51-5.68) in 50-59 and 4.79 (CI95% 2.49-9.22) in 60-69 years. The mortality odds ratio was 3.53 (CI95% 2.77-4.5) in rural place, 1.33 (CI95% 1.15-1.54) in men, and 2.44 (CI95% 2.09-2.85) in the road out of town and village. In addition, trend of motorcycle accidents mortality was increasing ( p <0.001). Motorcycle accidents injuries are more common in men, summer, young age and rural roads. These high risk groups need more attention, care and higher training.

    Introduction Patients with haematological malignancy admitted to intensive care have a high mortality. Adverse prognostic factors include the number of organ failures, invasive mechanical ventilation and previous bone marrow transplantation. Severity-of-illness scores may underestimate the mortality of critically ill patients with haematological malignancy. This study investigates the relationship between admission characteristics and outcome in patients with haematological malignancies admitted to intensive care units (ICUs) in England, Wales and Northern Ireland, and assesses the performance of three severity-of-illness scores in this population. Methods A secondary analysis of the Intensive Care National Audit and Research Centre (ICNARC) Case Mix Programme Database was conducted on admissions to 178 adult, general ICUs in England, Wales and Northern Ireland between 1995 and 2007. Multivariate logistic regression analysis was used to identify factors associated with hospital mortality. The Acute Physiology and Chronic Health Evaluation (APACHE) II score, Simplified Acute Physiology Score (SAPS) II and ICNARC score were evaluated for discrimination (the ability to distinguish survivors from nonsurvivors); and the APACHE II, SAPS II and ICNARC mortality probabilities were evaluated for calibration (the accuracy of the estimated probability of survival). Results There were 7,689 eligible admissions. ICU mortality was 43.1% (3,312 deaths) and acute hospital mortality was 59.2% (4,239 deaths). ICU and hospital mortality increased with the number of organ failures on admission. Admission factors associated with an increased risk of death were bone marrow transplant, Hodgkin's lymphoma, severe sepsis, age, length of hospital stay prior to intensive care admission, tachycardia, low systolic blood pressure, tachypnoea, low Glasgow Coma Score, sedation, PaO2:FiO2, acidaemia, alkalaemia, oliguria, hyponatraemia, hypernatraemia, low haematocrit, and uraemia.

    Until now, few epidemiological studies have focused on the association between ambient particulate matter pollution and mental and behavioral disorders, especially in developing countries. Thus, a time-series study on the short-term association between both fine and inhalable particles (PM 2.5 and PM 10 ) and daily hospital admissions for mental and behavioral disorders in Shijiazhuang, China was conducted, from 2014 to 2016. An over-dispersed, generalized additive model was used to analyze the associations after controlling for time trend, weather conditions, day of the week, and holidays. In addition, the modification effects of age, sex, and season were estimated. A total of 9156 cases of hospital admissions for mental and behavioral disorders were identified. A 10 μg/m 3 increase in a 3-day average concentration (lag02) of PM 2.5 and PM 10 correspond to an increase of 0.48% (95% confidence interval (CI): 0.18-0.79%) and 0.32% (95% CI: 0.03-0.62%) in daily hospital admission for mental and behavioral disorders, respectively. We found stronger associations of PM 2.5 and PM 10 with mental and behavioral disorders in male and elder individuals (≥45 years) than in female and younger individuals (<45 years). Further, results indicated a generally stronger association of PM 2.5 with mental and behavioral disorders in the cool season than in the warm season. This research found a significant association between ambient PM 2.5 and PM 10 and hospital admission for mental and behavioral disorders in Shijiazhuang, China. Copyright © 2018 Elsevier B.V.

    To assess the presence and risk factors of intestinal carriage of extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE) among patients admitted to the University Teaching Hospital of Butare and among their attending caregivers, and to analyse the acquisition of ESBL-PE carriage during hospital stay and associated factors. We screened 392 patients and their attending caregivers at admission and discharge for ESBL-PE carriage. Bacterial species were determined using the API-20E system, and antimicrobial susceptibility testing was performed by agar disc diffusion. Data on socio-economic status, diet, behaviour, household assets, livestock and hospital procedures were collected. At admission, 50% of the patients showed intestinal ESBL-PE carriage (Escherichia coli, 51%; Klebsiella pneumoniae, 39%; Enterobacter cloacae, 19%) as did 37% of their caregivers. Co-resistance was common but no carbapenem resistance was detected. At discharge, the proportion of ESBL-PE-colonised patients increased to 65% (caregivers, 47%) with almost complete carriage in paediatric patients (93%). The acquisition rate among initially non-colonised patients was 55% (or, 71/1000 patient days). Independent predictors of admission carriage included a colonised caregiver, prior antibiotic intake, egg consumption and neglecting to boil drinking water, whereas being a paediatric patient, undergoing surgery and male gender predicted acquisition during hospitalisation. Abundant admission carriage of ESBL-PE and a high acquisition rate in a Rwandan university hospital point to potential intrahospital transmission and community dissemination. Caregivers are an additional source of possible spread. Risk factors of colonisation such as diet and water source need to be tackled to prevent the further emergence and spread of ESBL-PE. © 2016 John Wiley & Sons Ltd.

    Text and data mining play an important role in obtaining insights from Health and Hospital Information Systems. This paper presents a text mining system for detecting admissions marked as positive for several diseases: Lung Cancer, Breast Cancer, Colon Cancer, Secondary Malignant Neoplasm of Respiratory and Digestive Organs, Multiple Myeloma and Malignant Plasma Cell Neoplasms, Pneumonia, and Pulmonary Embolism. We specifically examine the effect of linking multiple data sources on text classification performance. Support Vector Machine classifiers are built for eight data source combinations, and evaluated using the metrics of Precision, Recall and F-Score. Sub-sampling techniques are used to address unbalanced datasets of medical records. We use radiology reports as an initial data source and add other sources, such as pathology reports and patient and hospital admission data, in order to assess the research question regarding the impact of the value of multiple data sources. Statistical significance is measured using the Wilcoxon signed-rank test. A second set of experiments explores aspects of the system in greater depth, focusing on Lung Cancer. We explore the impact of feature selection; analyse the learning curve; examine the effect of restricting admissions to only those containing reports from all data sources; and examine the impact of reducing the sub-sampling. These experiments provide better understanding of how to best apply text classification in the context of imbalanced data of variable completeness. Radiology questions plus patient and hospital admission data contribute valuable information for detecting most of the diseases, significantly improving performance when added to radiology reports alone or to the combination of radiology and pathology reports. Overall, linking data sources significantly improved classification performance for all the diseases examined. However, there is no single approach that suits all scenarios; the choice of the

    In adults, early traumatic coagulopathy and shock are both common and independently associated with mortality. There are little data regarding both the incidence and association of early coagulopathy and shock on outcomes in pediatric patients with traumatic injuries. Our objective was to determine whether coagulopathy and shock on admission are independently associated with mortality in children with traumatic injuries. A retrospective review of the Joint Theater Trauma Registry from U.S. combat support hospitals in Iraq and Afghanistan from 2002 to 2009 was performed. Coagulopathy was defined as an international normalized ratio of ≥1.5 and shock as a base deficit of ≥6. Laboratory values were measured on admission. Primary outcome was inhospital mortality. Univariate analyses were performed on all admission variables followed by reverse stepwise multivariate logistic regression to determine independent associations. Combat support hospitals in Iraq and Afghanistan. Patients <18 yrs of age with Injury Severity Score, international normalized ratio, base deficit, and inhospital mortality were included. Of 1998 in the cohort, 744 (37%) had a complete set of data for analysis. None. The incidence of early coagulopathy and shock were 27% and 38.3% and associated with mortality of 22% and 16.8%, respectively. After multivariate logistic regression, early coagulopathy had an odds ratio of 2.2 (95% confidence interval 1.1-4.5) and early shock had an odds ratio of 3.0 (95% confidence interval 1.2-7.5) for mortality. Patients with coagulopathy and shock had an odds ratio of 3.8 (95% confidence interval 2.0-7.4) for mortality. In children with traumatic injuries treated at combat support hospitals, coagulopathy and shock on admission are common and independently associated with a high incidence of inhospital mortality. Future studies are needed to determine whether more rapid and accurate methods of measuring coagulopathy and shock as well as if early goal

    The 2009 pandemic influenza A (H1N1) virus was accompanied by high morbidity and mortality. The aim of this study was to describe the clinical characteristics of patients with documented 2009 influenza A (H1N1) virus admitted to a reference chest hospital, the disease outcome, and risk factors associated with ICU admission. We assessed 109 subjects admitted to the respiratory infection unit of a hospital for chest disease with signs and symptoms of the 2009 influenza A (H1N1) virus between April 2009 and December 2010. Demographic data, comorbidities, clinical signs and symptoms, laboratory tests, radiographic findings, treatment, and final outcomes were all recorded. Factors associated with severe disease requiring ICU admission were determined. Ninety subjects (82.5%) had laboratory-confirmed 2009 influenza A (H1N1). Sixty-four percent of these subjects had pneumonia on admission, 26% had respiratory failure, and 11% required care in the ICU. Dyspnea and the presence of infiltrates on chest x-rays were the most common signs among the subjects with H1N1. All subjects were treated with antiviral therapy, and 75% received antibiotic treatment based on their clinical and laboratory findings. The predictive factors of ICU admission were severe hypoxemia and lymphocytosis. The outcome of subjects with influenza A (H1N1) virus infection was influenced by the severity of the disease on admission, the subjects' underlying conditions, and complications during hospitalization.

    This aim of this study was to characterize trends in alcohol-related hospital admissions among middle-aged and older adults from 1993 to 2010 in relation to age, gender, race, and cohort membership. This study utilized repeated cross-sectional data from the Nationwide Inpatient Sample. Using alcohol-related classified admissions, yearly rates and longitudinal trends of alcohol-related inpatient hospitalizations based on age, period, birth cohort, gender, and race were estimated. Among those aged 45 and older, admissions rose from an estimated 610,634 to more than 1,134,876, and rates of any alcohol-related diagnosis also increased from 1993 to 2010. Rates for men were consistently higher than women, and rates for Blacks were higher than Whites. Age was associated with decreasing rates, but post-World War II cohorts displayed higher rates over time. Rates of alcohol-related admissions are increasing among adults above age 45, which may be a function of cohort effects. Training the health care workforce is crucial to respond to this trend. © The Author(s) 2015.

    Background Air pollution in Darwin, Northern Australia, is dominated by smoke from seasonal fires in the surrounding savanna that burn during the dry season from April to November. Our aim was to study the association between particulate matter less than or equal to 10 microns diameter (PM10) and daily emergency hospital admissions for cardio-respiratory diseases for each fire season from 1996 to 2005. We also investigated whether the relationship differed in indigenous Australians; a disadvantaged population sub-group. Methods Daily PM10 exposure levels were estimated for the population of the city from visibility data using a previously validated model. We used over-dispersed Poisson generalized linear models with parametric smoothing functions for time and meteorology to examine the association between admissions and PM10 up to three days prior. An interaction between indigenous status and PM10 was included to examine differences in the impact on indigenous people. Results We found both positive and negative associations and our estimates had wide confidence intervals. There were generally positive associations between respiratory disease and PM10 but not with cardiovascular disease. An increase of 10 μg/m3 in same-day estimated ambient PM10 was associated with a 4.81% (95%CI: -1.04%, 11.01%) increase in total respiratory admissions. When the interaction between indigenous status and PM10 was assessed a statistically different association was found between PM10 and admissions three days later for respiratory infections of indigenous people (15.02%; 95%CI: 3.73%, 27.54%) than for non-indigenous people (0.67%; 95%CI: -7.55%, 9.61%). There were generally negative estimates for cardiovascular conditions. For non-indigenous admissions the estimated association with total cardiovascular admissions for same day ambient PM10 and admissions was -3.43% (95%CI: -9.00%, 2.49%) and the estimate for indigenous admissions was -3.78% (95%CI: -13.4%, 6.91%), although ambient PM

    The purpose of this study was to describe (1) the aggressiveness of care in a population of patients who die of lung cancer and (2) differences in care between a sample of lung cancer patients who died in an acute care hospital (DH) and a sample of lung cancer patients who were admitted to hospital during the last six months of life but were discharged and died elsewhere (DO). All lung cancer deaths in 2002 were identified in the provincial registry. Cases were linked to administrative sources of health care data to describe the population as a whole and the aggressiveness of the care that they received. Primary data were collected from a province-wide sample of patients' hospital charts focusing on reasons for admission, care in hospital, advanced planning, pain, and disposition. In total, 5,855 patients who died of lung cancer in 2002 were eligible for inclusion in the cohort. Rates of in-hospital death, emergency room visits, intensive care unit admissions, and chemotherapy use near the end of life were 59.5%, 32.2%, 5.5%, and 4.6%, respectively. The records of 491 patients were abstracted for this study. The DH and DO groups were similar with respect to age, gender, neighborhood income level, and extent of metastatic disease. The most common chief complaints were shortness of breath, pain, inability to cope at home, and altered level of consciousness. Compared to patients in the DO group, those in the DH group presented with pain more often (19% vs. 10%, P<0.005) and were more likely to be admitted with progressive chest malignancy (30% vs. 21%, P<0.05). Regardless of reason for admission, pain was commonly documented as a problem during admission: 73.5% in the DH group and 62.4% in the DO group (P<0.05). Lung cancer patients are heavy users of acute care beds and the emergency room at the end of life. Those who do or do not die in hospital are similar in many respects but our results suggest those dying in hospital have more problems with pain and burden from

    Objective To investigate whether exposure to aircraft noise increases the risk of hospitalization for cardiovascular diseases in older people (≥65 years) residing near airports. Design Multi-airport retrospective study of approximately 6 million older people residing near airports in the United States. We superimposed contours of aircraft noise levels (in decibels, dB) for 89 airports for 2009 provided by the US Federal Aviation Administration on census block resolution population data to construct two exposure metrics applicable to zip code resolution health insurance data: population weighted noise within each zip code, and 90th centile of noise among populated census blocks within each zip code. Setting 2218 zip codes surrounding 89 airports in the contiguous states. Participants 6 027 363 people eligible to participate in the national medical insurance (Medicare) program (aged ≥65 years) residing near airports in 2009. Main outcome measures Percentage increase in the hospitalization admission rate for cardiovascular disease associated with a 10 dB increase in aircraft noise, for each airport and on average across airports adjusted by individual level characteristics (age, sex, race), zip code level socioeconomic status and demographics, zip code level air pollution (fine particulate matter and ozone), and roadway density. Results Averaged across all airports and using the 90th centile noise exposure metric, a zip code with 10 dB higher noise exposure had a 3.5% higher (95% confidence interval 0.2% to 7.0%) cardiovascular hospital admission rate, after controlling for covariates. Conclusions Despite limitations related to potential misclassification of exposure, we found a statistically significant association between exposure to aircraft noise and risk of hospitalization for cardiovascular diseases among older people living near airports.

    The International Classification of Diseases (ICD) is the main classification system used for population-based traumatic brain injury (TBI) surveillance activities but does not contain direct information on injury severity. International Classification of Diseases-based injury severity measures can be empirically derived or mapped to the Abbreviated Injury Scale, but no single approach has been formally recommended for TBI. The aim of this study was to compare the accuracy of different ICD-based injury severity measures for predicting in-hospital mortality and intensive care unit (ICU) admission in TBI patients. We conducted a population-based retrospective cohort study. We identified all patients 16 years or older with a TBI diagnosis who received acute care between April 1, 2006, and March 31, 2013, from the Quebec Hospital Discharge Database. The accuracy of five ICD-based injury severity measures for predicting mortality and ICU admission was compared using measures of discrimination (area under the receiver operating characteristic curve [AUC]) and calibration (calibration plot and the Hosmer-Lemeshow goodness-of-fit statistic). Of 31,087 traumatic brain-injured patients in the study population, 9.0% died in hospital, and 34.4% were admitted to the ICU. Among ICD-based severity measures that were assessed, the multiplied derivative of ICD-based Injury Severity Score (ICISS-Multiplicative) demonstrated the best discriminative ability for predicting in-hospital mortality (AUC, 0.858; 95% confidence interval, 0.852-0.864) and ICU admissions (AUC, 0.813; 95% confidence interval, 0.808-0.818). Calibration assessments showed good agreement between observed and predicted in-hospital mortality for ICISS measures. All severity measures presented high agreement between observed and expected probabilities of ICU admission for all deciles of risk. The ICD-based injury severity measures can be used to accurately predict in-hospital mortality and ICU admission in TBI

    Diurnal temperature range (DTR) and temperature change between neighboring days (TCN) are important meteorological indicators closely associated with global climate change. However, up to date, there have been no studies addressing the impacts of both DTR and TCN on emergency hospital admissions for schizophrenia. We conducted a time-series analysis to assess the relationship between temperature variability and daily schizophrenia onset in Hefei, an inland city in southeast China. Daily meteorological data and emergency hospital admissions for schizophrenia from 2005 to 2014 in Hefei were collected. After stratifying by season of birth, Poisson generalized linear regression combined with distributed lag nonlinear model (DLNM) was used to examine the relationship between temperature variability and schizophrenia, adjusting for long-term trend and seasonality, mean temperature, and relative humidity. Our analysis revealed that extreme temperature variability may increase the risk for schizophrenia onset among patients born in spring, while no such association was found in patients born in summer and autumn. In patients born in spring, the relative risks of extremely high DTR comparing the 95th and 99th percentiles with the reference (50th, 10 °C) at 3-day lag were 1.078 (95 % confidence interval (CI) 1.025-1.135) and 1.159 (95 % CI 1.050-1.279), respectively. For TCN effects, only comparing 99th percentile with reference (50th, 0.7 °C) was significantly associated with emergency hospital admissions for schizophrenia (relative risk (RR) 1.111, 95 % CI 1.002-1.231). This study suggested that exposure to extreme temperature variability in short-term may trigger later days of schizophrenia onset for patients born in spring, which may have important implications for developing intervention strategies to prevent large temperature variability exposure.

    Due to the novel reimbursement policies, hospitals face substantial conflicts regarding best patient care and optimal utilization of resources. In order to optimize patient treatment, a central patients admission (CPA) unit has been established. All patients electively referred to the hospital were primarily treated by a medical specialist at the CPA unit. According to an appropriateness evaluation protocol established with the medical service of the health insurances of Bavaria ("MDK-Bayern"), patients were treated as inpatients or outpatients. The impact of this novel admission procedure was assessed for a period of 30 months. Within 30 months following establishment of the CPA unit, 10% of the patients were treated as outpatients, whereas 90% of referred patients were admitted as inpatients. Nonetheless, numbers of inpatients increased by 20.7% after 24 months compared to 12 months following establishment of the CPA unit with a substantial increase of patients referred by external medical specialists. In addition, there were no cases of inappropriate admission. The CPA unit is an ideal instrument for treating patients cross-sectorally as well as more effectively and economically advocating reorganization. Establishment of a CPA unit leads to greater satisfaction among patients, referring physicians, and medical staff.

    Alcohol dependence (AD) is associated with an increase in physical comorbidities. The effects of these diseases on general hospital-based mortality are unclear. Consequently, we conducted a mortality study in which we investigated if the burden of physical comorbidities and their relevance on general hospital-based mortality differs between individuals with and without AD during a 12.5-year observation period in general hospital admissions. During 1 January 2000 and 30 June 2012, 23,371 individuals with AD were admitted at least once to seven General Manchester Hospitals. Their physical comorbidities with a prevalence≥1% were compared to those of 233,710 randomly selected hospital controls, group-matched for age and gender (regardless of primary admission diagnosis or specialized treatments). Physical comorbidities that increased the risk of hospital-based mortality (but not outside of the hospital) during the observation period were identified using multiple logistic regression analyses. Hospital-based mortality rates were 20.4% in the AD sample and 8.3% in the control sample. Individuals with AD compared to controls had a higher burden of physical comorbidities, i.e. alcoholic liver and pancreatic diseases, diseases of the conducting airways, neurological and circulatory diseases, diseases of the upper gastrointestinal tract, renal diseases, cellulitis, iron deficiency anemia, fracture neck of femur, and peripheral vascular disease. In contrast, coronary heart related diseases, risk factors of cardiovascular disease, diverticular disease and cataracts were less frequent in individuals with AD than in controls. Thirty-two individual physical comorbidities contributed to the prediction of hospital-based mortality in univariate analyses in the AD sample; alcoholic liver disease (33.7%), hypertension (16.9%), chronic obstructive pulmonary disease (14.1%), and pneumonia (13.3%) were the most frequent diagnoses in deceased individuals with AD.

    Study objective: The extent of social inequalities in children's hospitalisation risks was examined in terms of socioeconomic status and parents' nationality. This was considered in terms of inpatient treatment attributable to a number of diagnoses (ICD-9), especially infectious diseases and psychiatric disorders. Design and setting: Analyses were performed with records of a German statutory health insurance comprising 48 412 (52.8% male and 47.2% female) children and adolescents of 15 years of age or younger who were co-insured between 1987 and 1996. Classification of socioeconomic position was based on parental occupational position. Results: Social inequalities in terms of hospital admissions attributable to acute diseases were rather small. The only exception were infections of the respiratory organs: in the highest status positions as compared with the lowest one the relative risk for being admitted was RR=0.22 (95% CI 0.06 to 0.89). However, length of stay in hospital was significantly related to socioeconomic position for infections of the upper respiratory tract and infections of the respiratory organs, with children and adolescents with the lowest socioeconomic background having spent the longest periods in hospital. With regard to nationality, pneumonia/flu was the only diagnostic category where relative risks for being admitted were higher in non-German children and adolescents (RR=1.5; 95% CI 1.2 to 1.8). Conversely, hospital admissions attributable to psychiatric diagnoses were significantly lower among non-German patients (RR=0.43; 95% CI 0.30 to 0.61), thus suggesting differential utilisation patterns according to nationality. Conclusions: Health inequalities in children's and adolescents' hospital admissions in Germany are small and inconsistent if parents' socioeconomic status and nationality are taken as criterion. Yet, children of lower status background stay longer in hospital if suffering from highly prevalent infectious diseases. This last

    We used a Poisson regression to compare daily hospital admissions of elderly people for acute gastrointestinal illness in Boston against daily variations in drinking water quality over an 11-year period, controlling for weather, seasonality and time trends. The Massachusetts Water Resources Authority (MWRA), which provides non-filtered water to 1.5 million people in the greater Boston area, changed its disinfection method from chlorination to ozonation during the study period so we were also able to evaluate changes in risk associated with the change in disinfection method. Other available water quality data from the MWRA included turbidity, fecal coliforms, UV-absorbance, and planktonic algae and cyanobacteriae concentrations. Daily weather, rainfall data and water temperature were also available. Low water temperature, increases in turbidity and, to a lesser extent, in fecal coliform and cyanobacteriae were associated with a higher risk of hospital admissions, while the shift from chlorination to ozonation has possibly reduced the health risk. The MWRA complied with US drinking water regulations throughout the study period. Copyright © 2014 Elsevier Ltd. All rights reserved.

    There is emerging evidence, largely from studies in Europe and North America, that economic deprivation increases the magnitude of morbidity and mortality related to air pollution. Two major reasons why this may be true are that the poor experience higher levels of exposure to air pollution, and they are more vulnerable to its effects--in other words, due to poorer nutrition, less access to medical care, and other factors, they experience more health impact per unit of exposure. The relations among health, air pollution, and poverty are likely to have important implications for public health and social policy, especially in areas such as the developing countries of Asia where air pollution levels are high and many live in poverty. The aims of this study were to estimate the effect of exposure to air pollution on hospital admissions of young children for acute lower respiratory infection (ALRI*) and to explore whether such effects differed between poor children and other children. ALRI, which comprises pneumonia and bronchiolitis, is the largest single cause of mortality among young children worldwide and is responsible for a substantial burden of disease among young children in developing countries. To the best of our knowledge, this is the first study of the health effects of air pollution in Ho Chi Minh City (HCMC), Vietnam. For these reasons, the results of this study have the potential to make an important contribution to the growing literature on the health effects of air pollution in Asia. The study focused on the short-term effects of daily average exposure to air pollutants on hospital admissions of children less than 5 years of age for ALRI, defined as pneumonia or bronchiolitis, in HCMC during 2003, 2004, and 2005. Admissions data were obtained from computerized records of Children's Hospital 1 and Children's Hospital 2 (CH1 and CH2) in HCMC. Nearly all children hospitalized for respiratory illnesses in the city are admitted to one of these two pediatric

    Background: It is unknown whether this burden of disease of lower respiratory tract infections is comparable across the Canadian Arctic. The objectives of this surveillance study were to compare the rates of hospital admission for lower respiratory tract infection and the severity of infection across Arctic Canada, and to describe the responsible viruses. Methods: We performed a prospective multicentre surveillance study of infants less than 1 year of age admitted in 2009 with lower respiratory tract infection to all hospitals (5 regional, 4 tertiary) in the Northwest Territories, Nunavut and Nunavik to assess for regional differences. Nasopharyngeal aspirates were processed by means of a polymerase chain reaction respiratory viral panel, testing for 20 respiratory viruses and influenza A (H1N1). The role of coinfection was assessed by means of regression analysis for length of stay (short: < 7 d; long: > 14 d). Outcomes compared included rates of lower respiratory tract infection, respiratory syncytial virus infection, transfer to tertiary hospital and severe lower respiratory tract infection (respiratory failure, intubation and mechanical ventilation, and/or cardiopulmonary resuscitation). Results: There were 348 admissions for lower respiratory tract infection in the population of interest in 2009. Rates of admission per 1000 live births varied significantly, from 39 in the Northwest Territories to 456 in Nunavik (p < 0.001). The rates of tertiary admissions and severe lower respiratory tract infection per 1000 live births in the Northwest Territories were 5.6 and 1.4, respectively, compared to 55.9 and 17.1, respectively, in Nunavut and 52.0 and 20.0, respectively, in Nunavik (p ≤ 0.001). Respiratory syncytial virus was the most common virus identified (124 cases [41.6% of those tested]), and coinfection was detected in 51 cases (41.1%) of infection with this virus. Longer length of stay was associated with coinfection (odds ratio [OR] 2.64) and underlying

    Observational studies and trials from low-income countries indicate that measles vaccine has beneficial nonspecific effects, protecting against non–measles-related mortality. It is not known whether measles vaccine protects against hospital admissions. Between 2003 and 2007, 6417 children who had received the third dose of diphtheria, tetanus, and pertussis vaccine were randomly assigned to receive measles vaccine at 4.5 months or no measles vaccine; all children were offered measles vaccine at 9 months of age. Using hospital admission data from the national pediatric ward in Bissau, Guinea-Bissau, we compared admission rates between enrollment and the 9-month vaccination in Cox models, providing admission hazard rate ratios (HRRs) for measles vaccine versus no measles vaccine. All analyses were conducted stratified by sex and reception of neonatal vitamin A supplementation (NVAS). Before enrollment the 2 groups had similar admission rates. Following enrollment, the measles vaccine group had an admission HRR of 0.70 (95% confidence interval [CI], .52–.95), with a ratio of 0.53 (95% CI, .32–.86) for girls and 0.86 (95% CI, .58–1.26) for boys. For children who had not received NVAS, the admission HRR was 0.53 (95% CI, .34–.84), with an effect of 0.30 (95% CI, .13–.70) for girls and 0.73 (95% CI, .42–1.28) for boys (P = .08, interaction test). The reduction in admissions was separately significant for measles infection (admission HRR, 0 [95% CI, 0–.24]) and respiratory infections (admission HRR, 0.37 [95% CI, .16–.89]). Early measles vaccine may have major benefits for infant morbidity patterns and healthcare costs. Clinical trials registration NCT00168558. PMID:24436454

    To demonstrate the feasibility of using stochastic simulation methods for the solution of a large-scale Markov decision process model of on-line patient admissions scheduling. The problem of admissions scheduling is modeled as a Markov decision process in which the states represent numbers of patients using each of a number of resources. We investigate current state-of-the-art real time planning methods to compute solutions to this Markov decision process. Due to the complexity of the model, traditional model-based planners are limited in scalability since they require an explicit enumeration of the model dynamics. To overcome this challenge, we apply sample-based planners along with efficient simulation techniques that given an initial start state, generate an action on-demand while avoiding portions of the model that are irrelevant to the start state. We also propose a novel variant of a popular sample-based planner that is particularly well suited to the elective admissions problem. Results show that the stochastic simulation methods allow for the problem size to be scaled by a factor of almost 10 in the action space, and exponentially in the state space. We have demonstrated our approach on a problem with 81 actions, four specialities and four treatment patterns, and shown that we can generate solutions that are near-optimal in about 100s. Sample-based planners are a viable alternative to state-based planners for large Markov decision process models of elective admissions scheduling. Copyright © 2014 Elsevier B.V. All rights reserved.

    To determine whether a routine admission screening in surgical wards and intensive care units (ICUs) was effective in reducing methicillin-resistant Staphylococcus aureus (MRSA) infections-particularly nosocomial MRSA infections-for the whole hospital. The study used a single-centre prospective quasi-experimental design to evaluate the effect of the MRSA screening policy on the incidence density of MRSA-infected/nosocomial MRSA-infected patients/1000 patient-days (pd) in the whole hospital. The effect on incidence density was calculated by a segmented regression analysis of interrupted time series with 30 months prior to and 24 months after a 6 month implementation period. The MRSA screening policy had a highly significant hospital-wide effect on the incidence density of MRSA infections. It showed a significant change in both level [-0.163 MRSA-infected patients/1000 pd, 95% confidence interval (CI): -0.276 to -0.050] and slope (-0.01 MRSA-infected patients/1000 pd per month, 95% CI: -0.018 to -0.003) after the implementation of the MRSA screening policy. A decrease in the MRSA infections by 57% is a conservative estimate of the reduction between the last month before (0.417 MRSA-infected patients/1000 pd) and month 24 after the implementation of the MRSA screening policy (0.18 MRSA-infected patients/1000 pd). Equivalent results were found in the analysis of nosocomial MRSA-infected patients/1000 pd. This is the first hospital-wide study that investigates the impact of introducing admission screening in ICUs and non-ICUs as a single intervention to prevent MRSA infections performed with a time-series regression analysis. Admission screening is a potent tool in controlling the spread of MRSA infections in hospitals.

    There is evidence about time-dependent fracture rates in different settings and situations. Lacking are data about underlying time-dependent fall risk patterns. The objective of the study was to analyse fall rates as a function of time after admission to sub-acute hospital units and to evaluate the time-dependent impact of clinical factors at baseline on fall risk. This retrospective cohort study used data of 5,255 patients admitted to sub-acute units in a geriatric rehabilitation clinic in Germany between 2010 and 2014. Falls, personal characteristics and functional status at admission were extracted from the hospital information system. The rehabilitation stay was divided in 3-day time-intervals. The fall rate was calculated for each time-interval in all patients combined and in subgroups of patients. To analyse the influence of covariates on fall risk over time multivariate negative binomial regression models were applied for each of 5 time-intervals. The overall fall rate was 10.2 falls/1,000 person-days with highest fall risks during the first week and decreasing risks within the following weeks. A particularly pronounced risk pattern with high fall risks during the first days and decreasing risks thereafter was observed in men, disoriented people, and people with a low functional status or impaired cognition. In disoriented patients, for example, the fall rate decreased from 24.6 falls/1,000 person-days in day 2-4 to about 13 falls/1,000 person-days 2 weeks later. The incidence rate ratio of baseline characteristics changed also over time. Fall risk differs considerably over time during sub-acute hospitalisation. The strongest association between time and fall risk was observed in functionally limited patients with high risks during the first days after admission and declining risks thereafter. This should be considered in the planning and application of fall prevention measures.

    Despite their high prevalence, little is known about the effects of substance use disorders and active substance use on the suicide risk or length-of-stay of psychiatric inpatients. This study examines the relationship between active substance use at the time of psychiatric hospitalization and changes in suicide risk measures and length-of-stay. Admission and discharge ratings on the Suicide Status Form-II-R, diagnoses, and toxicology data from 2,333 unique psychiatric inpatients were examined. Data for patients using alcohol, tetrahydrocannabinol, methamphetamines, cocaine, benzodiazepines, opiates, barbiturates, phencyclidine, and multiple substances on admission were compared with data from 1,426 admissions without substance use. Patients with substance use by toxicology on admission had a 0.9 day shorter length-of-stay compared to toxicology-negative patients. During initial nurse evaluation on the inpatient unit, these patients reported lower suicide measures (i.e., suicidal ideation frequency, overall suicide risk, and wish-to-die). No significant between-group differences were seen at discharge. Patients admitted with a substance use disorder diagnosis had a 1.0 day shorter length-of-stay than those without, while those with a substance use disorder diagnosis and positive toxicology reported the lowest measures of suicidality on admission. These results remained independent of psychiatric diagnosis. For acute psychiatric inpatients, suicide risk is higher and length-of-stay is longer in patients with substance use disorders who are NOT acutely intoxicated compared with patients without a substance use disorder. Toxicology-positive patients are less suicidal on admission and improve faster than their toxicology-negative counterparts. This study gives support to the clinical observation that acutely intoxicated patients may stabilize quickly with regard to suicidal urges and need for inpatient care.

    To calculate the incidence rates and direct costs, and to describe hospital admissions for malaria in Spain between 1999 and 2002. Retrospective study of hospital admissions whose fundamental discharge diagnosis was malaria (codes CIE-9 from 084.0 to 084.9), using the national surveillance system for hospital data (CMBD) between 1999 and 2002. 2,044 hospitalizations for malaria were recorded in Spain (incidence rate 1.3 cases per 100,000 inhabitants/year). 20.6% were children under the age of 15. We found an increasing linear trend in the incidence rate of malaria in the 0-4 age group (p < 0.001). 57.3% of malaria cases were due to Plasmodium falciparum, 11.5% to P. vivax, 2.4% to P. malariae and 3.3% to P. ovale. On the other hand, 64% of admissions occurred between summer and autumn, a seasonal pattern attributable to P. falciparum. The annual cost of the hospitalizations was euro 1.2 million. There is an increasing number of hospitalizations in Spain due to malaria, which might be higher in coming years. This fact mainly owes to the population movements we are currently experiencing.

    There has been little research on the accessibility and quality of primary care services for epilepsy and emergency hospital admissions for epilepsy. We examined time trends in admissions for epilepsy in England between 2004-2005 and 2010, and the association of admission rates with population and primary care factors. The units of analysis were the registered populations of 8622 general practices. We used negative binomial regression to model indicators from the Quality and Outcomes Framework, the UK's primary care pay for performance scheme, to measure the accessibility and quality of care for epilepsy, and supply of general practitioners, after adjustment for population factors. The mean indirectly standardised admission rate decreased from 122.9 to 102.6 (-16.5%; P<0.001) over the study period, while the mean percentage of patients seizure free increased from 65.3% to 74.9% (P<0.001). In the multivariable analysis, a one unit increase in the percentage of seizure free adult patients on epilepsy drugs predicted a 0.20% decrease (IRR=0.9980; 95% CI: 0.9974-0.9986) in admission rate. The percentage of patients who were able to book a GP appointment over two days ahead predicted a 0.12% decrease (IRR=0.9988; 95% CI: 0.9982-0.9994). The deprivation score of practice populations (IRR=1.0179; P<0.001) and general practitioner supply (IRR=1.0022; P<0.001) were both positively associated with admission rates. Patient access to primary care appointments and percentage of patients who have been recorded as seizure free for 12 months were associated with lower admission rates. However the effect sizes are small relative to that of population deprivation. Copyright © 2014 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

    No children-specified review and meta-analysis paper about the short-term effect of fine particulate matter (PM2.5) on hospital admissions and emergency department visits for asthma has been published. We calculated more precise pooled effect estimates on this topic and evaluated the variation in effect size according to the differences in study characteristics not considered in previous studies. Two authors each independently searched PubMed and EMBASE for relevant studies in March, 2016. We conducted random effect meta-analyses and mixed-effect meta-regression analyses using retrieved summary effect estimates and 95% confidence intervals (CIs) and some characteristics of selected studies. The Egger's test and funnel plot were used to check publication bias. All analyses were done using R version 3.1.3. We ultimately retrieved 26 time-series and case-crossover design studies about the short-term effect of PM2.5 on children's hospital admissions and emergency department visits for asthma. In the primary meta-analysis, children's hospital admissions and emergency department visits for asthma were positively associated with a short-term 10 μg/m3 increase in PM2.5 (relative risk, 1.048; 95% CI, 1.028 to 1.067; I2=95.7%). We also found different effect coefficients by region; the value in Asia was estimated to be lower than in North America or Europe. We strengthened the evidence on the short-term effect of PM2.5 on children's hospital admissions and emergency department visits for asthma. Further studies from other regions outside North America and Europe regions are needed for more generalizable evidence.

    Palliative care summaries are used by general practices to provide structured anticipatory care information to those providing care during the out-of-hours period. We hypothesised that the availability of a palliative care summary for individuals with established cancer would influence emergency hospital admission during the out-of-hours period. Each consultation with Grampian Medical Emergency Department (GMED) is recorded on the ADASTRA software system and the nature of the consultation is Read coded. We retrospectively reviewed consultations between 1 January 2011 and 31 December 2011 which had been coded as 'neoplasm' or 'terminal care'. The availability of a palliative care summary on ADASTRA and admission status were recorded. χ(2) Test of association was performed. Binary logistic regression was used for multivariate analysis exploring the effect of a palliative care summary on admission, while adjusting for important confounders. 401 patients with established cancer were identified who had presented to GMED in 2011. 35.7% had a palliative care summary available on ADASTRA. Of the 401 contacts, 100 patients were admitted to hospital. Not having a palliative care summary made admission significantly more likely; χ(2)=12.480, p=0.001. (OR 2.425, 95% CI 1.412 to 4.165). Availability of a structured palliative care plan can aid decision making in the out-of-hours period and prevent unplanned hospital admissions.

    Medication has been suggested as a potential risk factor for diverticular disease. The objective of this study was to investigate the association between the intake of corticosteroids, indometacin or aspirin and diverticular disease. This was a prospective population-based cohort study of middle-aged women in the Swedish Mammography Cohort. Use of corticosteroids (oral or inhaled), indometacin or aspirin in 1997 was determined from questionnaires. Cases of diverticular disease were identified from the Swedish national registers until the end of 2010. The relative risk (RR) of diverticular disease requiring hospital admission according to the use of medication was estimated using Cox proportional hazards models, adjusted for age, body mass index, physical activity, fibre intake, diabetes, hypertension, alcohol, smoking and education. A total of 36 586 middle-aged women in the Swedish Mammography Cohort were included, of whom 674 (1.8 per cent) were hospitalized with diverticular disease at least once. Some 7.2 per cent of women reported intake of oral corticosteroids and 8.5 per cent use of inhaled corticosteroids. In multivariable analysis, women who reported oral corticosteroid intake had a 37 per cent (RR 1.37, 95 per cent c.i. 1.06 to 1.78; P = 0.012) increased risk of diverticular disease compared with those who reported no intake at all. Use of inhaled corticosteroids was associated with an even more pronounced increase in risk of 71 per cent (RR 1.71, 1.36 to 2.14; P < 0.001). There was a significant dose-response relationship, with the risk increasing with longer duration of inhaled corticosteroids (P for trend < 0.001). Use of indometacin (2.5 per cent of women) or aspirin (44.2 per cent) did not influence the risk. There was a significant relationship between corticosteroids (especially inhaled) and diverticular disease requiring hospital admission. © 2014 BJS Society Ltd. Published by John Wiley & Sons Ltd.

    People with dementia have worse outcomes associated with hospital admission, are more likely to have interventions and are less likely to be offered palliative care than people without dementia. Advance care planning for care home residents has been shown to reduce hospital admissions without increasing mortality. Studies have shown that staff confidence in managing delirium, a common reason for admission, improves with training. A service combining education for care home staff and advance care planning for care home residents with dementia was introduced to care homes in Boston, UK. There were improvements in staff confidence in recognition, prevention, management and knowledge of factors associated with delirium and dysphagia. 92% of carers rated the service >9/10. Admissions fell by 37% from baseline in the first year and 55% in the second and third years. All but one resident died in the preferred place of care. © 2016 Royal College of Physicians.

    to verify the occurrence and the causes of hospital readmissions within a year after discharge from hospitalizations due to traffic accidents. victims of multiple traumas due to traffic accidents were included, who were admitted to an Intensive Care Unit. Sociodemographic data, accident circumstances, body regions affected and cause of readmission were collected from the patient histories. among the 109 victims of traffic accidents, the majority were young and adult men. Most hospitalizations due to accidents involved motorcycle drivers (56.9%). The causes of the return to the hospital were: need to continue the surgical treatment (63.2%), surgical site infection (26.3%) and fall related to the physical sequelae of the trauma (10.5%). The rehospitalization rate corresponded to 174/1,000 people/year. the hospital readmission rate in the study population is similar to the rates found in other studies. Victims of severe limb traumas need multiple surgical procedures, lengthier hospitalizations and extended rehabilitation.
