Hospitalisation for ambulatory care sensitive conditions (ACSHs) has become a recognised tool to measure access to primary care. Timely and effective outpatient care is highly relevant to refugee populations given the past exposure to torture and trauma, and poor access to adequate health care in their countries of origin and during flight. Little is known about ACSHs among resettled refugee populations. With the aim of examining the hypothesis that people from refugee backgrounds have higher ACSHs than people born in the country of hospitalisation, this study analysed a six-year state-wide hospital discharge dataset to estimate ACSH rates for residents born in refugee-source countries and compared them with the Australia-born population. Hospital discharge data between 1 July 1998 and 30 June 2004 from the Victorian Admitted Episodes Dataset were used to assess ACSH rates among residents born in eight refugee-source countries, and compare them with the Australia-born average. Rate ratios and 95% confidence levels were used to illustrate these comparisons. Four categories of ambulatory care sensitive conditions were measured: total, acute, chronic and vaccine-preventable. Country of birth was used as a proxy indicator of refugee status. When compared with the Australia-born population, hospitalisations for total and acute ambulatory care sensitive conditions were lower among refugee-born persons over the six-year period. Chronic and vaccine-preventable ACSHs were largely similar between the two population groups. Contrary to our hypothesis, preventable hospitalisation rates among people born in refugee-source countries were no higher than Australia-born population averages. More research is needed to elucidate whether low rates of preventable hospitalisation indicate better health status, appropriate health habits, timely and effective care-seeking behaviour and outpatient care, or overall low levels of health care-seeking due to other more pressing needs during the initial period of resettlement. It is important to unpack dimensions of health status and health care access in refugee populations through ad-hoc surveys as the refugee population is not a homogenous group despite sharing a common experience of forced displacement and violence-related trauma.

To describe parents' perspectives of health care provider actions that helped or did not around the time of infant/child's intensive care unit (ICU) death. Semistructured interviews with 63 parents (Black, White, and Hispanic) 7 months post infant/child death were audio-recorded, transcribed, analyzed, and themes identified. What helped most: compassionate, sensitive staff; understandable explanations of infant's/child's condition; experienced, competent nurses; providers did everything to help infant/child; and parents' involvement in care decisions. What did not help: insensitive, nonsupportive staff; conflict between providers and parents; communication problems around the death; inexperienced nurses and doctors; parents not understanding child's disease, care, complications. Compassionate, sensitive staff and understandable explanations of children's conditions were most helpful; insensitive, nonsupportive staff least helpful by gender, racial group, or care setting. Conflict between providers and parents was most problematic for minority parents and mothers.

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.

The role of mental illness and addiction in acute care use for chronic medical conditions that are sensitive to ambulatory care management requires focussed attention. This study examines how mental illness or addiction affects risk for repeat hospitalization and/or emergency department use for ambulatory care-sensitive conditions (ACSCs) among high-cost users of medical care. A retrospective, population-based cohort study using data from Ontario, Canada. Among the top 10% of medical care users ranked by cost, we determined rates of any and repeat care use (hospitalizations and emergency department [ED] visits) between April 1, 2011, and March 31, 2012, for 14 consensus established ACSCs and compared them between those with and without diagnosed mental illness or addiction during the 2 years prior. Risk ratios were adjusted (aRR) for age, sex, residence, and income quintile. Among 314,936 high-cost users, 35.9% had a mental illness or addiction. Compared to those without, individuals with mental illness or addiction were more likely to have an ED visit or hospitalization for any ACSC (22.8% vs. 19.6%; aRR, 1.21; 95% confidence interval [CI], 1.20-1.23). They were also more likely to have repeat ED visits or hospitalizations for the same ACSC (6.2% vs. 4.4% of those without; aRR, 1.48; 95% CI, 1.44-1.53). These associations were stronger in stratifications by mental illness diagnostic subgroup, particularly for those with a major mental illness. The presence of mental illness and addiction among high-cost users of medical services may represent an unmet need for quality ambulatory and primary care.

Hospitalizations for ambulatory care sensitive conditions (ACSH) have been proposed as an indirect indicator of the effectiveness and quality of care provided by primary health care. To investigate the association of ACSH rates with population socioeconomic factors and with characteristics of primary health care. Cross-sectional, ecologic study. Using hospital discharge data, ACSH were selected from the list of conditions validated for Spain. All 34 health districts in the Region of Madrid, Spain. Individuals aged 65 years or older residing in the region of Madrid between 2001 and 2003, inclusive. Age- and gender-adjusted ACSH rates in each health district. The adjusted ACSH rate per 1000 population was 35.37 in men and 20.45 in women. In the Poisson regression analysis, an inverse relation was seen between ACSH rates and the socioeconomic variables. Physician workload was the only health care variable with a statistically significant relation (rate ratio of 1.066 [95% CI; 1.041-1.091]). These results were similar in the analyses disaggregated by gender. In the multivariate analyses that included health care variables, none of the health care variables were statistically significant. ACSH may be more closely related with socioeconomic variables than with characteristics of primary care activity. Therefore, other factors outside the health system must be considered to improve health outcomes in the population.

To verify the hospitalization trend for primary care sensitive-conditions in Pelotas, Rio Grande do Sul, Brazil from 1998 to 2012. An ecological study compared hospitalizations rates of the city of Pelotas with the rest of state of Rio Grande do Sul. Analysis was conducted using direct standardization of rates, coefficients were stratified by sex and the Poisson regression was used. Hospitalizations for sensitive conditions decreased in Pelotas and Rio Grande do Sul. In Pelotas, a 63.8% decrease was detected in the period observed, and there was a 43.1% decrease in the state of Rio Grande do Sul. Poisson regression coefficients showed a decrease of 7% in Pelotas and of 4% in the rest of Rio Grande do Sul each year. During the study period, several changes were introduced in the Brazilian Unified Health System ("Sistema Único de Saúde") that may have influenced the results, including changes in administration, health funding, and a complete reworking of primary care through the creation of the Family Health Strategy program ("Estratégia Saúde da Família").

To compare the prevalence of hospitalizations for ambulatory care sensitive conditions (ACSC) in children with and without autism spectrum disorder (ASD) and to compare inpatient health care utilization (total charges and length of stay) for the same conditions in children with and without ASD. The 2009 Kids' Inpatient Database was used to examine hospitalizations for ACSC in children within 3 cohorts: those with ASD, those with chronic conditions (CC) without ASD, and those with no CC. The proportion of hospitalizations for ACSC in the ASD cohort was 55.9%, compared with 28.2% in the CC cohort and 22.9% in the no-CC cohort (P < .001). Hospitalized children with ASD were more likely to be admitted for a mental health condition, epilepsy, constipation, pneumonia, dehydration, vaccine-preventable diseases, underweight, and nutritional deficiencies compared with the no-CC cohort. Compared with the CC cohort, the ASD cohort was more likely to be admitted for mental health conditions, epilepsy, constipation, dehydration, and underweight. Hospitalized children with ASD admitted for mental health conditions had significantly higher total charges and longer LOS compared with the other 2 cohorts. The proportion of potentially preventable hospitalizations is higher in hospitalized children with ASD compared with children without ASD. These data underscore the need to improve outpatient care of children with ASD, especially in the areas of mental health care and seizure management. Future research should focus on understanding the reasons for increased inpatient health care utilization in children with ASD admitted for mental health conditions.

Regional, coordinated care for time-sensitive and high-risk medical conditions is a priority in the United States. A necessary precursor to coordinated regional care is regions that are actionable from clinical and policy standpoints. The Dartmouth Atlas of Health Care, the major health care referral construct in the United States, uses regions that cross state and county boundaries, limiting fiscal or political ownership by key governmental stakeholders in positions to create incentive and regulate regional care coordination. Our objective is to develop and evaluate referral regions that define care patterns for patients with acute myocardial infraction, acute stroke, or trauma, yet also preserve essential political boundaries. We developed a novel set of acute care referral regions using Medicare data in the United States from 2011. For acute myocardial infraction, acute stroke, or trauma, we iteratively aggregated counties according to patient home location and treating hospital address, using a spatial algorithm. We evaluated referral political boundary preservation and spatial accuracy for each set of referral regions. The new set of referral regions, the Pittsburgh Atlas, had 326 distinct regions. These referral regions did not cross any county or state borders, whereas 43.1% and 98.1% of all Dartmouth Atlas hospital referral regions crossed county and state borders. The Pittsburgh Atlas was comparable to the Dartmouth Atlas in measures of spatial accuracy and identified larger at-risk populations for all 3 conditions. A novel and straightforward spatial algorithm generated referral regions that were politically actionable and accountable for time-sensitive medical emergencies.

2018-04-01

To synthesize concepts and approaches related to the analysis of patterns or processes of care and patient's outcomes into a comprehensive model of care trajectories, focusing on hospital readmissions for patients with chronic ambulatory care sensitive conditions (ACSCs). Narrative literature review. Published studies between January 2000 and November 2017, using the concepts of 'continuity', 'pathway', 'episode', and 'trajectory', and focused on readmissions and chronic ACSCs, were collected in electronic databases. Qualitative content analysis was performed with emphasis on key constituents to build a comprehensive model. Specific common constituents are shared by the concepts reviewed: they focus on the patient, aim to measure and improve outcomes, follow specific periods of time and consider other factors related to care providers, care units, care settings, and treatments. Using these common denominators, the comprehensive '6W' multidimensional model of care trajectories was created. Considering patients' attributes and their chronic ACSCs illness course ('who' and 'why' dimensions), this model reflects their patterns of health care use across care providers ('which'), care units ('where'), and treatments ('what'), at specific periods of time ('when'). The '6W' model of care trajectories could provide valuable information on 'missed opportunities' to reduce readmission rates and improve quality of both ambulatory and inpatient care.

Care coordination across healthcare organizations depends upon health information exchange. Various policies and laws govern permissible exchange, particularly when the information includes privacy sensitive conditions. The Department of Veterans Affairs (VA) privacy policy has required either blanket consent or manual sensitivity review prior to exchanging any health information. The VA experience has been an expensive, administratively demanding burden on staffand Veterans alike, particularly for patients without privacy sensitive conditions. Until recently, automatic sensitivity determination has not been feasible. This paper proposes a policy-driven algorithmic approach (Security Labeling Service or SLS) to health information exchange that automatically detects the presence or absence of specific privacy sensitive conditions and then, to only require a Veteran signed consent for release when actually present. The SLS was applied successfully to a sample of real patient Consolidated-Clinical Document Architecture(C-CDA) documents. The SLS identified standard terminology codes by both parsing structured entries and analyzing textual information using Natural Language Processing (NLP). PMID:28269828

Ecological conditions are expected to have an important influence on individuals' investment in cooperative care. However, the nature of their effects is unclear: both favorable and unfavorable conditions have been found to promote helping behavior. Recent studies provide a possible explanation for these conflicting results by suggesting that increased ecological variability, rather than changes in mean conditions, promote cooperative care. However, no study has tested whether increased ecological variability promotes individual-level helping behavior or the mechanisms involved. We test this hypothesis in a long-term study population of the cooperatively breeding banded mongoose, Mungos mungo , using 14 years of behavioral and meteorological data to explore how the mean and variability of ecological conditions influence individual behavior, body condition, and survival. Female body condition was more sensitive to changes in rainfall leading to poorer female survival and pronounced male-biased group compositions after periods of high rainfall variability. After such periods, older males invested more in helping behavior, potentially because they had fewer mating opportunities. These results provide the first empirical evidence for increased individual helping effort in more variable ecological conditions and suggest this arises because of individual differences in the effect of ecological conditions on body condition and survival, and the knock-on effect on social group composition. Individual differences in sensitivity to environmental variability, and the impacts this has on the internal structure and composition of animal groups, can exert a strong influence on the evolution and maintenance of social behaviors, such as cooperative care.

A sensitive scalp is a frequent problem in daily clinical practice and often represents a major challenge for dermatologists. The objective was to evaluate the efficacy of a Northamerican Virginian Witch Hazel (Hamamelis virginiana)-based shampoo and tonic (Erol(®) Energy) for treatment of the sensitive scalp. Retrospective observational study of male and female patients given Erol(®) Energy products in the period between August 2010 and December 2013 at the Center for Dermatology and Hair Diseases Professor Trüeb to treat irritable scalp conditions or as concomitant treatment to minoxidil therapy for androgenetic alocepia. Shampoo was applied successfully in 1,373 patients (1,233 women and 140 men). Patients reported improvement of subjective manifestations of irritation and rated tolerance of both products as good to excellent. During this period, 369 (26.9%) have received Erol(®) shampoo more than once. The choice of appropriate hair-care products represents an important aspect in the management of the sensitive scalp and related conditions. With the Erol(®) Energy hair-care products, the advantages of H. virginiana are available for successful treatment of the scalp, especially in the context of problems associated with red scalp, scalp burn-out, and the use of topical minoxidil for androgenetic alopecia.

Ambulatory Sensitive Hospitalisations (ASH) are a group of conditions potentially preventable through interventions delivered in the primary health care setting. ASH rates are consistently higher for Māori compared with non-Māori. This study aimed to establish Māori experience of factors driving the use of hospital services for ASH conditions, including barriers to accessing primary care. A telephone questionnaire exploring pathways to ASH was administered to Māori (n=150) admitted to Auckland and Waitemata District Health Board (DHB) hospitals with an ASH condition between January 1st-June 30th 2015. A cohort of 1,013 participants were identified; 842 (83.1%) were unable to be contacted. Of the 171 people contactable, 150 agreed to participate, giving an overall response rate of 14.8% and response rate of contactable patients of 87.7%. Results demonstrated high rates of self-reported enrolment, utilisation and preference for primary care. Many participants demonstrated appropriate health seeking behaviour and accurate recall of diagnoses. While financial barriers to accessing primary care were reported, non-financial barriers including lack of after-hours provision (12.6% adults, 37.7% children), appointment availability (7.4% adults, 17.0% children) and lack of transport (13.7% adults, 20.8% children) also featured in participant responses. Interventions to reduce Māori ASH include: timely access to primary care through electronic communications, increased appointment availability, extended opening hours, low cost after-hours care and consistent best management of ASH conditions in general practice through clinical pathways. Facilitated enrolment of ASH patients with no general practitioner could also reduce ASH. Research into transport barriers and enablers for Māori accessing primary care is required to support future interventions.

Ambulatory care sensitive conditions at out-of-hospital emergence services in Croatia: a longitudinal study based on routinely collected data.

Kostanjšek, Diana; Benčić, Miro; Keglević, Mladenka Vrcić

2014-12-01

Conditions for which a hospital and emergency utilization can be considered avoidable are often referred as ambulatory care sensitive conditions (ACSCs). Until now, there has been no published research related to ACSCs in Croatia. This study was undertaken with the aim of determining the trends relating to ACSCs in out-of-hospital ES from 1995-2012. The study is based on data from the Croatian Health Service Yearbooks. Five chronic and three acute conditions were chosen: diabetes, hypertension, congestive heart failure, angina pectoris, asthma and COPD, bacterial pneumonia, urinary tract infections and skin infections. The results indicate that the ES in Croatia is overused, and consequently ACSCs are over-represented; 23.3% Croatian citizens visited the ES and around 15% of all diagnoses belonged to the ACSCs, with decreased trend. The leading diagnosis is hypertension, followed by asthma and COPD. For a better understanding of the importance of ACSC within the Croatian context, further research is needed.

Objective To estimate the impact of a national primary care pay for performance scheme, the Quality and Outcomes Framework in England, on emergency hospital admissions for ambulatory care sensitive conditions (ACSCs). Design Controlled longitudinal study. Setting English National Health Service between 1998/99 and 2010/11. Participants Populations registered with each of 6975 family practices in England. Main outcome measures Year specific differences between trend adjusted emergency hospital admission rates for incentivised ACSCs before and after the introduction of the Quality and Outcomes Framework scheme and two comparators: non-incentivised ACSCs and non-ACSCs. Results Incentivised ACSC admissions showed a relative reduction of 2.7% (95% confidence interval 1.6% to 3.8%) in the first year of the Quality and Outcomes Framework compared with ACSCs that were not incentivised. This increased to a relative reduction of 8.0% (6.9% to 9.1%) in 2010/11. Compared with conditions that are not regarded as being influenced by the quality of ambulatory care (non-ACSCs), incentivised ACSCs also showed a relative reduction in rates of emergency admissions of 2.8% (2.0% to 3.6%) in the first year increasing to 10.9% (10.1% to 11.7%) by 2010/11. Conclusions The introduction of a major national pay for performance scheme for primary care in England was associated with a decrease in emergency admissions for incentivised conditions compared with conditions that were not incentivised. Contemporaneous health service changes seem unlikely to have caused the sharp change in the trajectory of incentivised ACSC admissions immediately after the introduction of the Quality and Outcomes Framework. The decrease seems larger than would be expected from the changes in the process measures that were incentivised, suggesting that the pay for performance scheme may have had impacts on quality of care beyond the directly incentivised activities.

Canine parvovirus (CPV) and canine distemper virus (CDV) are highly infectious and often fatal diseases with worldwide distributions, and are important population management considerations in animal shelters. A point-of-care ELISA test kit is available to detect serum antibodies to CPV and CDV, and presumptively to predict protective status. The aim of this study was to determine the diagnostic accuracy of the test compared to CPV hemagglutination inhibition titers and CDV serum neutralization titers determined by a reference laboratory, using sera collected from dogs housed at animal shelters. The ELISA test was used under both field and laboratory conditions and duplicate specimens were processed using an extra wash step. The test kit yielded accurate results (CPV: sensitivity 92.3%, specificity 93.5%; CDV: sensitivity 75.7%, specificity 91.8%) under field conditions. CDV sensitivity was improved by performing the test under laboratory conditions and using an optical density (OD) meter (laboratory performed 94.0%; OD 88.1%). Point-of-care ELISA testing for serum CPV and CDV antibody titers was demonstrated to be a useful tool for determining antibody status when making decisions regarding the need for CPV and/or CDV vaccination and also in animal shelters for population management.

2004-01-01

Objective To examine the effects of health maintenance organization (HMO) penetration on preventable hospitalizations. Data Source Hospital inpatient discharge abstracts for 932 urban counties in 22 states from the Healthcare Cost and Utilization Project (HCUP) State Inpatient Databases (SID), hospital data from American Hospital Association (AHA) annual survey, and population characteristics and health care capacity data from Health Resources and Services Administration (HRSA) Area Resource File (ARF) for 1998. Methods Preventable hospitalizations due to 14 ambulatory care sensitive conditions were identified using the Agency for Healthcare Research and Quality (AHRQ) Prevention Quality Indicators. Multiple regressions were used to determine the association between preventable hospitalizations and HMO penetration while controlling for demographic and socioeconomic characteristics and health care capacity of the counties. Principal Findings A 10 percent increase in HMO penetration was associated with a 3.8 percent decrease in preventable hospitalizations (95 percent confidence interval, 2.0 percent–5.6 percent). Advanced age, female gender, poor health, poverty, more hospital beds, and fewer primary care physicians per capita were significantly associated with more preventable hospitalizations. Conclusions Our study suggests that HMO penetration has significant effects in reducing preventable hospitalizations due to some ambulatory care sensitive conditions. PMID:15032958

Validating diagnostic information on the Minimum Data Set in Ontario Hospital-based long-term care.

Over 20 countries currently use the Minimum Data Set Resident Assessment Instrument (MDS) in long-term care settings for care planning, policy, and research purposes. A full assessment of the quality of the diagnostic information recorded on the MDS is lacking. The primary goal of this study was to examine the quality of diagnostic coding on the MDS. Subjects for this study were admitted to Ontario Complex Continuing Care Hospitals (CCC) directly from acute hospitals between April 1, 1997 and March 31, 2005 (n = 80,664). Encrypted unique identifiers, common across acute and CCC administrative databases, were used to link administrative records for patients in the sample. After linkage, each resident had 2 sources of diagnostic information: the acute discharge abstract database and the MDS. Using the discharge abstract database as the reference standard, we calculated the sensitivity for each of 43 MDS diagnoses. Compared with primary diagnoses coded in acute care abstracts, 12 of 43 MDS diagnoses attained a sensitivity of at least 0.80, including 7 of the 10 diagnoses with the highest prevalence as an acute care primary diagnosis before CCC admission. Although the sensitivity was high for many of the most prevalent conditions, important diagnostic information is missed increasing the potential for suboptimal clinical care. Emphasis needs to be put on improving information flow across care settings during patient transitions. Researchers should exercise caution when using MDS diagnoses to identify patient populations, particularly those shown to have low sensitivity in this study.

North American Virginian Witch Hazel (Hamamelis virginiana): Based Scalp Care and Protection for Sensitive Scalp, Red Scalp, and Scalp Burn-Out

PubMed Central

Trüeb, Ralph M

2014-01-01

Background: A sensitive scalp is a frequent problem in daily clinical practice and often represents a major challenge for dermatologists. Objective: The objective was to evaluate the efficacy of a Northamerican Virginian Witch Hazel (Hamamelis virginiana)-based shampoo and tonic (Erol® Energy) for treatment of the sensitive scalp. Methods: Retrospective observational study of male and female patients given Erol® Energy products in the period between August 2010 and December 2013 at the Center for Dermatology and Hair Diseases Professor Trüeb to treat irritable scalp conditions or as concomitant treatment to minoxidil therapy for androgenetic alocepia. Results: Shampoo was applied successfully in 1,373 patients (1,233 women and 140 men). Patients reported improvement of subjective manifestations of irritation and rated tolerance of both products as good to excellent. During this period, 369 (26.9%) have received Erol® shampoo more than once. Conclusions: The choice of appropriate hair-care products represents an important aspect in the management of the sensitive scalp and related conditions. With the Erol® Energy hair-care products, the advantages of H. virginiana are available for successful treatment of the scalp, especially in the context of problems associated with red scalp, scalp burn-out, and the use of topical minoxidil for androgenetic alopecia.

2018-04-01

To explore effects of disease prevalence adjustment on ambulatory care-sensitive hospitalization (ACSH) rates used for quality comparisons. County-level hospital administrative data on adults discharged from German hospitals in 2011 and prevalence estimates based on administrative ambulatory diagnosis data were used. A retrospective cross-sectional study using in- and outpatient secondary data was performed. Hospitalization data for hypertension, diabetes, heart failure, chronic obstructive pulmonary disease, and asthma were obtained from the German Diagnosis Related Groups (DRG) database. Prevalence estimates were obtained from the German Central Research Institute of Ambulatory Health Care. Crude hospitalization rates varied substantially across counties (coefficients of variation [CV] 28-37 percent across conditions); this variation was reduced by prevalence adjustment (CV 21-28 percent). Prevalence explained 40-50 percent of the observed variation (r = 0.65-0.70) in ACSH rates for all conditions except asthma (r = 0.07). Between 30 percent and 38 percent of areas moved into or outside condition-specific control limits with prevalence adjustment. Unadjusted ACSH rates should be used with caution for high-stakes public reporting as differences in prevalence may have a marked impact. Prevalence adjustment should be considered in models analyzing ACSH. © Health Research and Educational Trust.

2018-02-22

Limited research has been conducted into the identification of a valid and reliable screening measure for anxiety in aged care settings, despite it being one of the most common psychological conditions. This study aimed to determine an appropriate anxiety screening tool for aged care by comparing the reliability and validity of three commonly used measures and identifying specific cut-offs for the identification of generalized anxiety disorder (GAD). One-hundred and eighty nursing home residents (M age = 85.39 years) completed the GAI, HADS-A, and RAID, along with a structured diagnostic interview. Twenty participants (11.1%) met DSM-5 criteria for GAD. All measures had good psychometric properties , although reliability estimates for the HADS-A were sub-optimal. Privileging sensitivity , the GAI cut-off score of 9 gave sensitivity of 90.0% and specificity of 86.3%; HADS-A cut-off of 6 gave sensitivity of 90.0% and specificity of 80.6%; and RAID cut-off of 11 gave sensitivity of 85.0% and specificity of 72.5%. While all three measures had adequate reliability, validity, and cut-scores with high levels of sensitivity and specificity to detect anxiety within aged care, the GAI was the most consistently reliable and valid measure for screening for GAD.

Surrogate decision making and intellectual virtue.

PubMed

Bock, Gregory L

2014-01-01

Patients can be harmed by a religiously motivated surrogate decision maker whose decisions are contrary to the standard of care; therefore, surrogate decision making should be held to a high standard. Stewart Eskew and Christopher Meyers proposed a two-part rule for deciding which religiously based decisions to honor: (1) a secular reason condition and (2) a rationality condition. The second condition is based on a coherence theory of rationality, which they claim is accessible, generous, and culturally sensitive. In this article, I will propose strengthening the rationality condition by grounding it in a theory of intellectual virtue, which is both rigorous and culturally sensitive.

Leppin, Aaron L.; Montori, Victor M.; Gionfriddo, Michael R.

2015-01-01

An increasing proportion of healthcare resources in the United States are directed toward an expanding group of complex and multimorbid patients. Federal stakeholders have called for new models of care to meet the needs of these patients. Minimally Disruptive Medicine (MDM) is a theory-based, patient-centered, and context-sensitive approach to care that focuses on achieving patient goals for life and health while imposing the smallest possible treatment burden on patients’ lives. The MDM Care Model is designed to be pragmatically comprehensive, meaning that it aims to address any and all factors that impact the implementation and effectiveness of care for patients with multiple chronic conditions. It comprises core activities that map to an underlying and testable theoretical framework. This encourages refinement and future study. Here, we present the conceptual rationale for and a practical approach to minimally disruptive care for patients with multiple chronic conditions. We introduce some of the specific tools and strategies that can be used to identify the right care for these patients and to put it into practice. PMID:27417747

2013-01-01

Racial/ethnic and socioeconomic disparities regarding untreated oral disease exist for older adults, and poor oral health diminishes quality of life. The ElderSmile program integrated screening for diabetes and hypertension into its community-based oral health activities at senior centers in northern Manhattan. The program found a willingness among minority seniors (aged ≥ 50 years) to be screened for primary care sensitive conditions by dental professionals and a high level of unrecognized disease (7.8% and 24.6% of ElderSmile participants had positive screening results for previously undiagnosed diabetes and hypertension, respectively). Dental professionals may screen for primary care–sensitive conditions and refer patients to health care providers for definitive diagnosis and treatment. The ElderSmile program is a replicable model for community-based oral and general health screening. PMID:23597378

Early childhood environment related to microbial exposure and the occurrence of atopic disease at school age.

There is a growing body of evidence that the early childhood environment with respect to day care attendance, older siblings, pet ownership, and early life airway infections may protect from developing atopic disease. Few studies have distinguished between atopic sensitization and symptoms, and none have evaluated independent contributions for all of these different environmental conditions. Examine independent effects on atopic sensitization and symptoms of day care attendance, older siblings, pet ownership, and early infancy's airway disease. A cross-sectional survey among 8-13-year-old school children with complete data for 1555 children. After adjustment for confounders, atopic sensitization occurred less frequently in children that had attended a day care centre (OR: 0.73, 95% CI: 0.55-0.98) or had a cat or dog before 2 years of age (OR: 0.78, 95% CI: 0.61-0.99). Having older siblings yielded a nonsignificant trend towards protection (OR: 0.88, 95% CI: 0.70-1.11). For symptoms, there was no relation with having older sibs, day care attendance and pet ownership, although there was a trend towards protection for the combination of atopy and symptoms. In contrast, children with doctors' treated airway disease before age 2, more frequently reported recent symptoms of wheeze, asthma, rhinitis, or dermatitis (all P < 0.05). Early life environmental exposure to day care, or pets may protect against atopic sensitization. Protection against symptoms only occurred if atopic sensitization was present as well.

2016-05-01

In developing countries, pneumonia is the leading cause of sickness and mortality in childhood, especially among vulnerable groups. The scope of this study was to analyze the factors associated with pneumonia in Yanomami children hospitalized for Ambulatory Care Sensitive Conditions (ACSC). Hospital admissions were divided into two groups: i) pneumonia; and ii) other causes, according to the Brazilian ACSC list. Adjusted hospitalization rates were estimated and unconditional logistic regression was used to analyze factors associated with pneumonia. Over 90% of the registered cases were considered ACSC. The adjusted rate of ACSC was 18.6/1000. The odds ratio of hospitalization for pneumonia was 2.7 (CI: 1.3-5.4) times higher in children aged between 0.1 and 5.9 months; 1.9 (CI: 1.1-3.3) times higher in children who were hospitalized for 8-14 days; and three (CI: 1.2-7.5) times higher in children with a secondary diagnosis of malnutrition. The excess of avoidable hospitalizations is a clear indication of the low quality of care and limited accessibility to primary health care in indigenous territories, which is contrary to the assistance model proposed by the indigenous healthcare subsystem in Brazil, which should in theory focus on welfare technologies based on primary health care.

Ability to predict discharge destination would be a useful way of optimizing posthospital care. We conducted a cross-sectional, multiple state study of inpatient services to assess the likelihood of home discharges in 2009 among Medicaid enrollees who were discharged following general hospitalizations. Analyses were conducted using hospitalization data from the states of California, Georgia, Michigan, and Mississippi. A total of 33 160 patients were included in the study among which 13 948 (42%) were discharged to their own homes and 19 212 (58%) were discharged to continue with institutional-based treatment. A multiple logistic regression model showed that gender, age, race, and having ambulatory care-sensitive conditions upon admission were significant predictors of home-based discharges. Females were at higher odds of home discharges in the sample (odds ratio [OR] = 1.631; 95% confidence interval [CI], 1.520-1.751), while patients with ambulatory care-sensitive conditions were less likely to get home discharges (OR = 0.739; 95% CI, 0.684-0.798). As the nation engages in the continued effort to improve the effectiveness of the health care system, cost savings are possible if providers and systems of care are able to identify admission factors with greater prospects for in-home services after discharge.

Background Family history is an important risk factor for many common chronic diseases, but it remains underutilised for diagnostic assessment and disease prevention in routine primary care. Aim To develop and validate a brief self-completed family history questionnaire (FHQ) for systematic primary care assessment for family history of diabetes, ischaemic heart disease, breast cancer, and colorectal cancer. Design and setting Two-stage diagnostic validation study in 10 general practices in eastern England. Method Participants aged 18–50 years were identified via random sampling from electronic searches of general practice records. Participants completed a FHQ then had a three-generational ‘gold standard’ pedigree taken, to determine disease risk category. In stage 1, the FHQ comprised 12 items; in stage 2 the shorter 6-item FHQ was validated against the same ‘gold standard’. Results There were 1147 participants (stage 1: 618; stage 2: 529). Overall, 32% were at increased risk of one or more marker conditions (diabetes 18.9%, ischaemic heart disease 13.3%, breast cancer 6.2%, colorectal cancer 2.2%). The shorter 6-item FHQ performed very well for all four conditions: pooled data from both stages show diabetes, sensitivity = 98%, specificity = 94%; ischaemic heart disease, sensitivity = 93%, specificity = 81%; breast cancer, sensitivity = 81%, specificity = 83%; colorectal cancer, sensitivity = 96%, specificity = 88%, with an area under the receiver operating characteristic curve of 0.90 for males and 0.89 for females. Conclusion This brief self-completed FHQ shows good diagnostic accuracy for identifying people at higher risk of four common chronic diseases. It could be used in routine primary care to identify patients who would be most likely to benefit from a more detailed pedigree and risk assessment, and consequent management strategies.

Izugbara, C Otutubikey; Afangideh, A Isong

2005-03-01

This study addresses the quest for rural-based health care services among women in urban Nigeria relying on a large qualitative database obtained from 63 Igbo women living in Aba, Nigeria. Results indicate that urban Igbo women of different socioeconomic and demographic characteristics utilize the services of different rural-based health care providers-indigenous healers, traditional birth attendants (TBAs), faith/spiritual, western-trained doctors and nurses as well as chemist shopkeepers-for conditions ranging from infertility, through child birthing and abortions, to swollen body, epilepsy, bone setting, and stubborn skin diseases. Major attractions to rural-based therapists were the failure of urban-based health services to provide cure, perceived mystical nature of conditions, need to conceal information on therapeutic progress and/or the nature of specific disease conditions, belief in rural-based therapists' ability to cure condition, and affordability of the services of rural-based health care providers. Findings underscore the critical implications of service characteristics, cultural beliefs, and the symbolic content of place(s) for care seekers' patterns of resort. We suggest that need exists for policies and programs aimed at making health care services in urban Nigeria more responsive to care seekers' socioeconomic and cultural sensitivities, integrating informal health care providers into Nigeria's health care system, and strengthening public health education in Nigeria.

This study tested the efficacy of a brief intervention (Cues program) with mothers of very low birth weight (VLBW <1500 g) infants. The primary hypothesis was that mothers in the Cues program would report lower levels of anxiety compared with mothers in the control group. Secondary hypotheses examined whether Cues mothers would report less stress, depression, and role restriction, and exhibit more sensitive interactive behavior, than control group mothers. A total of 121 mothers of VLBW infants were randomly assigned to either the experimental (Cues) intervention or an attention control (Care) condition. The Cues program combined training to reduce anxiety and enhance sensitivity. The control group received general information about infant care. Both programs were initiated during the neonatal intensive care unit stay. Maternal anxiety, stress, depression, and demographic variables were evaluated at baseline, prior to randomization. Postintervention outcomes were assessed during a home visit when the infant was ∼6 to 8 weeks of corrected age. Although mothers in the Cues group demonstrated greater knowledge of the content of the experimental intervention than mothers in the Care group, the groups did not differ in levels of anxiety, depression, and symptoms of posttraumatic stress. They were similar in their reports of parental role restrictions and stress related to the infant's appearance and behavior. Cues and Care group mothers were equally sensitive in interaction with their infants. Nonspecific attention was as effective as an early skill-based intervention in reducing maternal anxiety and enhancing sensitive behavior in mothers of VLBW infants.

A System Dynamics Approach to Modeling the Sensitivity of Inappropriate Emergency Department Utilization

NASA Astrophysics Data System (ADS)

Behr, Joshua G.; Diaz, Rafael

Non-urgent Emergency Department utilization has been attributed with increasing congestion in the flow and treatment of patients and, by extension, conditions the quality of care and profitability of the Emergency Department. Interventions designed to divert populations to more appropriate care may be cautiously received by operations managers due to uncertainty about the impact an adopted intervention may have on the two values of congestion and profitability. System Dynamics (SD) modeling and simulation may be used to measure the sensitivity of these two, often-competing, values of congestion and profitability and, thus, provide an additional layer of information designed to inform strategic decision making.

Sensitivity, specificity, positive and negative predictive values: diagnosing purple mange.

Collier, Jill; Huebscher, Roxana

2010-04-01

To shed light on several epidemiological terms for better understanding of diagnostic testing measures by using a mythical condition, "purple mange." Scientific literature related to epidemiology and statistical tests. Nurse practitioners (NPs) use the concepts of sensitivity (SEN), specificity (SPEC), positive predictive value (PPV), and negative predictive value (NPV) daily in primary care and specialty areas. In addition, PPV and NPV vary with the prevalence of a condition. At times, NPs misunderstand the meaning of these terms. In order to develop appropriate treatment plans, an understanding of the concepts of SEN, SPEC, PPV, and NPV is important for interpreting test results. The authors have used this mythical condition purple mange as a teaching tool for NP students.

Patient characteristics associated with hospitalisations for ambulatory care sensitive conditions in Victoria, Australia

PubMed Central

2012-01-01

Background Ambulatory Care Sensitive Conditions (ACSCs) are those for which hospitalisation is thought to be avoidable with the application of preventive care and early disease management, usually delivered in a primary care setting. ACSCs are used extensively as indicators of accessibility and effectiveness of primary health care. We examined the association between patient characteristics and hospitalisation for ACSCs in the adult and paediatric population in Victoria, Australia, 2003/04. Methods Hospital admissions data were merged with two area-level socioeconomic indexes: Index of Socio-Economic Disadvantage (IRSED) and Accessibility/Remoteness Index of Australia (ARIA). Univariate and multiple logistic regressions were performed for both adult (age 18+ years) and paediatric (age <18 years) groups, reporting odds ratios (OR) and 95% confidence intervals (CI) for a number of predictors of ACSCs admissions compared to non-ACSCs admissions. Results Predictors were much more strongly associated with ACSCs admissions compared to non-ACSCs admissions in the adult group than for the paediatric group with the exception of rurality. Significant adjusted ORs in the adult group were 1.06, 1.15, 1.13, 1.06 and 1.11 for sex, rurality, age, IRSED and ARIA variables, and 1.34, 1.04 and 1.09 in the paediatric group for rurality, IRSED and ARIA, respectively. Conclusions Disadvantaged paediatric and adult population experience more need of hospital care for ACSCs. Access barriers to primary care are plausible causes for the observed disparities. Understanding the characteristics of individuals experiencing access barriers to primary care will be useful for developing targeted interventions meeting the unique ambulatory needs of the population.

Objective To examine the effects of safety net hospital (SNH) closure and for-profit conversion on uninsured, Medicaid, and racial/ethnic minorities. Data Sources/Extraction Methods Hospital discharge data for selected states merged with other sources. Study Design We examined travel distance for patients treated in urban hospitals for five diagnosis categories: ambulatory care sensitive conditions, referral sensitive conditions, marker conditions, births, and mental health and substance abuse. We assess how travel was affected for patients after SNH events. Our multivariate models controlled for patient, hospital, health system, and neighborhood characteristics. Principal Findings Our results suggested that certain groups of uninsured and Medicaid patients experienced greater disruption in patterns of care, especially Hispanic uninsured and Medicaid women hospitalized for births. In addition, relative to privately insured individuals in SNH event communities, greater travel for mental health and substance abuse care was present for the uninsured. Conclusions Closure or for-profit conversions of SNHs appear to have detrimental access effects on particular subgroups of disadvantaged populations, although our results are somewhat inconclusive due to potential power issues. Policy makers may need to pay special attention to these patient subgroups and also to easing transportation barriers when dealing with disruptions resulting from reductions in SNH resources.

Regional rates of hospitalization for ambulatory care sensitive conditions (ACSC) are used to compare the availability and quality of ambulatory care but the risk adjustment for population health status is often minimal. The objectives of the study was to examine the impact of more extensive risk adjustment on regional comparisons and to investigate the relationship between various area-level factors and the properly adjusted rates. Our study is an observational study based on routine data of 2 million anonymous insured in 26 Swiss cantons followed over one or two years. A binomial negative regression was modeled with increasingly detailed information on health status (age and gender only, inpatient diagnoses, outpatient conditions inferred from dispensed drugs and frequency of physician visits). Hospitalizations for ACSC were identified from principal diagnoses detecting 19 conditions, with an updated list of ICD-10 diagnostic codes. Co-morbidities and surgical procedures were used as exclusion criteria to improve the specificity of the detection of potentially avoidable hospitalizations. The impact of the adjustment approaches was measured by changes in the standardized ratios calculated with and without other data besides age and gender. 25% of cases identified by inpatient main diagnoses were removed by applying exclusion criteria. Cantonal ACSC hospitalizations rates varied from to 1.4 to 8.9 per 1,000 insured, per year. Morbidity inferred from diagnoses and drugs dramatically increased the predictive performance, the greatest effect found for conditions linked to an ACSC. More visits were associated with fewer PAH although very high users were at greater risk and subjects who had not consulted at negligible risk. By maximizing health status adjustment, two thirds of the cantons changed their adjusted ratio by more than 10 percent. Cantonal variations remained substantial but unexplained by supply or demand. Additional adjustment for health status is required when using ACSC to monitor ambulatory care. Drug-inferred morbidities are a promising approach.

Sensitivity Analysis of Weather Variables on Offsite Consequence Analysis Tools in South Korea and the United States.

We studied sensitive weather variables for consequence analysis, in the case of chemical leaks on the user side of offsite consequence analysis (OCA) tools. We used OCA tools Korea Offsite Risk Assessment (KORA) and Areal Location of Hazardous Atmospheres (ALOHA) in South Korea and the United States, respectively. The chemicals used for this analysis were 28% ammonia (NH₃), 35% hydrogen chloride (HCl), 50% hydrofluoric acid (HF), and 69% nitric acid (HNO₃). The accident scenarios were based on leakage accidents in storage tanks. The weather variables were air temperature, wind speed, humidity, and atmospheric stability. Sensitivity analysis was performed using the Statistical Package for the Social Sciences (SPSS) program for dummy regression analysis. Sensitivity analysis showed that impact distance was not sensitive to humidity. Impact distance was most sensitive to atmospheric stability, and was also more sensitive to air temperature than wind speed, according to both the KORA and ALOHA tools. Moreover, the weather variables were more sensitive in rural conditions than in urban conditions, with the ALOHA tool being more influenced by weather variables than the KORA tool. Therefore, if using the ALOHA tool instead of the KORA tool in rural conditions, users should be careful not to cause any differences in impact distance due to input errors of weather variables, with the most sensitive one being atmospheric stability.

Asking For Help is Helpful: Validation of a Brief Lifestyle and Mood Assessment Tool in Primary Health Care

PubMed Central

Goodyear-Smith, Felicity; Arroll, Bruce; Coupe, Nicole

2009-01-01

PURPOSE The short, validated, self-administered, Case-finding and Help Assessment Tool (CHAT) for lifestyle and mental health assessment of adult patients in primary health care addresses inactivity, tobacco use, alcohol and other drug misuse, problem gambling, depression, anxiety and stress, abuse, and anger problems. For each issue patients are asked whether they would like help, either during the consultation or at a later date. This study aims to assess the value of the help question. METHODS Validation of the CHAT was conducted according to the STAndards for Reporting of Diagnostic accuracy studies statement for diagnostic tests. The setting was Auckland primary care practices with populations ranging from socioeconomically advantaged to deprived. Participants were 755 consecutive primary care patients who completed the CHAT plus the help question and reference standards. Sensitivity, specificity, and likelihood ratios with and without the addition of help the question were calculated. RESULTS Sensitivity ranged from 80% to 98% for the more-common conditions (depression, nicotine dependency, anxiety, problematic drinking). For each condition, specificity increased with the addition of the help question: depression increased from 73% to 98%; anxiety 77% to 99%; drinking 85% to 99%; verbal anger 92% to 99%; verbal abuse 97% to 99%; problematic drinking and gambling 98% to 99%. CONCLUSIONS The help question increased specificity without compromising sensitivity and reduced false positives, thereby increasing the positive predictive value. It allowed patients with comorbidities to prioritize issues they wished to address, indicate their readiness to change, promote self-determination, and give the clinician an indication of which topics to pursue.

Per-Capita Medicare Expenditures, Primary Care Access, Mortality Rates, and the Least Healthy Cities in America.

PubMed

Weeks, William B; Weinstein, James N

2017-01-01

To determine whether several measures of health care expenditures, access, and outcomes for the 25 recently identified "least healthy cities in America" differed from those in the rest of America. For 2004 and 2013, we obtained publicly available price-, age-, sex-, and race-adjusted hospital service area per-capita Medicare expenditures; age-, sex-, and race-adjusted Medicare mortality rates; and 2 indicators of primary care access: the proportion of enrollees having at least one ambulatory visit to a primary care clinician and the per-capita discharge rate for ambulatory care sensitive conditions. Using population weighting, we used Student t test for expenditure data and the chi-squared test for access and outcomes data to compare results of the 25 least healthy cities in aggregate to the rest of America. In both years examined, the 25 least healthy cities had substantially (about $500 per capita per year) and statistically significantly higher total per-capita Medicare Part A and Part B expenditures than the rest of America: about 4/5 of this difference was due to higher hospital and skilled nursing facility expenditures; physician expenditures were modestly lower in the 25 least healthy cities. While a greater proportion of Medicare beneficiaries in the least healthy cities had a primary care clinician both years, mortality and ambulatory care sensitive condition admission rates were substantially higher in the least healthy cities. Policymakers and health system executives should work together to determine the best asset allocation across determinants of health that maximizes value creation from a community health perspective.

Funding of tribal health programs linked to lower rates of hospitalization for conditions sensitive to ambulatory care.

PubMed

Korenbrot, Carol; Kao, Chi; Crouch, James A

2009-01-01

To determine first whether higher funding of Tribally Operated Health Programs (TOHP) is associated with reduced hospitalizations for ambulatory care sensitive conditions (HASC) of the American Indian/Alaska Natives (AIAN) who use them after adjusting for characteristics of TOHP service areas; and then whether improved ambulatory care with higher levels of funding mediates the association. Records in the Indian Health Service (IHS) for California of an annual average 42,153 AIAN users of TOHP from 1998 to 2002 were linked with state hospital discharge records. We analyzed 3181 HASC for AIAN users of 20 TOHP in multilevel Poisson regression models to determine the association of HASC rates adjusted for individual age and gender with the Federal Disparity Index for IHS funding of TOHP. Higher IHS funding of TOHP was associated with lower HASC rates for the AIAN who use them. For TOHP with less than 60% of health care costs funded, the HASC rate dropped 12% for every increase of 10% in funding. Even adjusting for characteristics of the service areas, the effect was only slightly reduced to a value of 9% to 11%. None of the available indicators of ambulatory care tested were found to mediate the effects. Our findings are consistent with a policy of IHS funding of all TOHP at a level of at least 60% of the health care costs of the AIAN who use the programs, instead of the current policy of 40%. Additional research is needed to understand what ambulatory care characteristics are improved by the funding.

Prospective study; patients were examined by ophthalmoscopy by general practitioners or opticians without fundal photographs and again with photographs, and assessments were compared to those of an ophthalmologist. Whether fundal photography improved the sensitivity of detection of retinopathy and referrable diabetic retinopathy, and whether this sensitivity could be improved by including a review of the films by the specialist. Diabetic retinopathy was detected by the ophthalmologist in 205 patients (20.5%) and referrable retinopathy in 49 (4.9%). The sensitivity of the general practitioners and opticians for referrable retinopathy with ophthalmoscopy was 65%, and improved to 84% with retinal photographs. General practitioners' sensitivity in detecting background retinopathy improved with photographs from 22% to 65%; opticians' sensitivity in detecting background retinopathy improved from 43% to 71%. The sensitivity of detecting referrable retinopathy by general practitioners improved from 56% to 80% with photographs; for opticians it improved from 75% to 88%. Combining modalities of screening by providing photography with specialist review of all films in addition to direct ophthalmoscopy through dilated pupils improves assessment and referral for diabetic retinopathy by general practitioners and opticians. With further training and experience, primary care screeners should be able to achieve a sensitivity that will achieve an effective, acceptable, and economical community based screening programme for this condition.

The Nova Scotia Environmental Health Centre is a treatment facility for individuals with chronic environmental conditions such as multiple chemical sensitivity, chronic fatigue syndrome, fibromyalgia, chronic respiratory conditions and in some cases chronic pain. The premise of care is to provide a patient-centred multidisciplinary care approach leading to self-management strategies. In order to measure the outcome of the treatment in these complex problems, with overlapping diagnoses, symptoms in many body systems and suspected environmental triggers, a detailed symptoms questionnaire was developed specifically for this patient population and validated. Results from a pilot study in which an abbreviated symptoms questionnaire based on the top reported symptoms captured in previous research was used to measure the efficacy of a multidisciplinary care approach in individuals with multiple chemical sensitivity are presented in this paper. The purpose of this study was to examine the extent, type and patterns of changes over time in the top reported symptoms with treatment measured using the abbreviated symptoms questionnaire. A total of 183 active and 109 discharged patients participated in the study where the health status was measured at different time periods of follow up since the commencement of treatment at the Centre. The findings from this study were successful in generating an initial picture of the nature and type of changes in these symptoms. For instance, symptoms such as difficulty concentrating, sinus conditions and tiredness showed early improvement, within the first 6 months of being in treatment, while others, such as fatigue, hoarseness or loss of voice, took longer while others showed inconsistent changes warranting further enquiry. A controlled longitudinal study is planned to confirm the findings of the pilot study. PMID:21197341

Microfluidic Surface Plasmon Resonance Sensors: From Principles to Point-of-Care Applications

PubMed Central

Wang, Da-Shin; Fan, Shih-Kang

2016-01-01

Surface plasmon resonance (SPR) is a label-free, highly-sensitive, and real-time sensing technique. Conventional SPR sensors, which involve a planar thin gold film, have been widely exploited in biosensing; various miniaturized formats have been devised for portability purposes. Another type of SPR sensor which utilizes localized SPR (LSPR), is based on metal nanostructures with surface plasmon modes at the structural interface. The resonance condition is sensitive to the refractive index change of the local medium. The principles of these two types of SPR sensors are reviewed and their integration with microfluidic platforms is described. Further applications of microfluidic SPR sensors to point-of-care (POC) diagnostics are discussed. PMID:27472340

The objective of this study was to advance our understanding and appreciation of the health status of young children in the state of Nevada in addition to their discrepancies in accessing health care. This study used the 2008-2009 Nevada Kindergarten Health Survey data of 11,073 children to assess both independent and combined effects of annual household income, race/ethnicity, primary language spoken in the family, rural/urban residence, and existing medical condition on access to health care. Annual household income was a significant predictor of access to health care, with middle and high income respondents having regular access to care compared to low income counterparts. Further, English proficiency was associated with access to health care, with English-speaking Hispanics over 2.5 times more likely to have regular access to care than Spanish-speaking Hispanics. Rural residents had decreased odds of access to preventive care and having a primary care provider, but unexpectedly, had increased odds of having access to dental care compared to urban residents. Finally, parents of children with no medical conditions were more likely to have access to care than those with a medical condition. The consequences for not addressing health care access issues include deteriorating health and well-being for vulnerable socio-demographic groups in the state. Altogether these findings suggest that programs and policies within the state must be sensitive to the specific needs of at risk groups, including minorities, those with low income, and regionally and linguistically isolated residents.

2013-07-01

The goal of this study was to identify the proportion of dehydration-related ambulatory care-sensitive condition hospitalizations, the reasons why these hospitalizations were preventable, and factors associated with preventability. A cross-sectional survey of primary care providers (PCPs), inpatient attending physicians, and parents was conducted in a consecutive series of children with ambulatory care-sensitive conditions admitted to an urban hospital over 14 months. Eighty-five children were diagnosed with dehydration. Their mean age was 1.6 years; most had public (74%) or no (17%) insurance, and were nonwhite (91%). The proportion of hospitalizations assessed as preventable varied from 12% for agreement among all 3 sources to 45% for any source. Parents identified inadequate prevention (50%), poor self-education (34%), and poor quality of care (38%) as key factors. PCPs identified parents providing insufficient home rehydration (33%), not visiting the clinic (25%), and not calling earlier (16%) as reasons. Inpatient attending physicians cited home rehydration (40%), delays in seeking care (40%), and lacking a PCP (20%) as contributors. Physicians (PCPs and inpatient attending physicians) were more likely than parents to describe the admission as inappropriate (75% vs 67% vs 0%; P < .01). Parental dissatisfaction with their child's PCP and a history of avoiding primary care due to costs or insurance problems were associated with significantly higher odds of preventable hospitalization. Up to 45% of dehydration-related hospitalizations may be preventable. Inadequate parental education by physicians, insufficient home rehydration, deferring clinic visits, insurance and cost barriers, inappropriate admissions, poor quality of care, and parental dissatisfaction with PCPs are the reasons that these hospitalizations might have been prevented.

Objectives. We compared the quality of care received by managed care Medicaid beneficiaries in counties with a choice of health plans and counties with no choice. Methods. This cross-sectional study among California Medicaid beneficiaries was conducted during 2002. We used a multivariate Poisson model to calculate adjusted rates of hospital admissions for ambulatory care–sensitive conditions by duration of plan enrollment. Results. Among beneficiaries with continuous Medicaid coverage, the percentage with 12 months of continuous enrollment in a health plan was significantly lower in counties with a choice of plans than in counties with no choice (79.2% vs 95.2%; P < .001). Annual ambulatory care–sensitive admission rates adjusted for age, gender, and race/ethnicity were significantly higher among beneficiaries living in counties with a choice of plans (6.58 admissions per 1000 beneficiaries; 95% confidence interval [CI] = 6.57, 6.58) than among those in counties with no choice (6.27 per 1000; 95% CI = 6.27, 6.28). Conclusions. Potential benefits of health plan choice may be undermined by transaction costs of delayed enrollment, which may increase the probability of hospitalization for ambulatory care–sensitive conditions.

Integrated health practices: development of a graduate nursing program.

Jossens, Marilyn O R; Ganley, Barbara J

2006-01-01

This article describes pedagogical issues in the development of a graduate nursing program in Integrated Health Practices (IHP), reports early experiences in the program, and asserts the importance of a graduate program in the specialty. The experience is described, and unique pedagogical issues encountered are discussed. While noting the contributions made to health and health care by Western medicine and nursing practice, the authors elaborate on the benefits of integrating western health care with less technological, less invasive, and less expensive holistic approaches. Diverse populations often require attention to specific chronic conditions, rather than to acute conditions, and constitutional requirements for overall health may be influenced by diverse health philosophies and practices. These requirements may be grounded in cultural and religious beliefs that must be incorporated into culturally sensitive plans of care. Clinical nurse specialists in IHP can offer knowledge and leadership to nursing practice, which address these complex, yet subtle health care issues.

Ambulatory Care Sensitive Conditions (ACSC) are a set of selected codes of hospital discharge diagnosis intended to measure avoidable hospitalizations. Primary Health Care Services may avoid the hospitalizations due to ACSC by applying any of the following interventions, that are characteristics of this level of care: a) primary prevention; b) secondary prevention, and c) tertiary prevention and rehabilitation. Observational, cross-sectional pilot study on 248,174 hospital discharges, from a population of 2,248,704 inhabitants in 161 Basic Health Care Units (BHCU), recorded in the minimum basic set of hospital discharge data in Catalonia during 1996. The complete list of diagnostic codes of ACSC, identified in the literature search, has been used. Crude and age-standardised hospitalisation rates have been estimated. Standardised hospitalisation ratio (SHR) has been computed to compare hospitalisation rates between BHCU. To analyse the effect of variables associated with high ACSC admission rates, multivariate analysis has been carried out by means of Poisson's regression. Hospitalisation due to ACSC account for 13% of all hospitalizations and 16% of hospital stay days. Acute and chronic diseases of the lower respiratory tract are the first cause of hospitalisation at any age group (< 5, 15-64 and > or = 65 years). The most common diagnostic groups, for all ages are respiratory disorders (acute and chronic diseases of the lower respiratory tract and pneumonia) and urinary tract conditions (pyelonephritis/urinary tract infection). The so-called self-limited health problems (ear, nose and throat mild infections/infections of the upper respiratory tract, febrile convulsions in children and gastroenteritis) account for more than 10% of all hospitalizations by ACSC, 45% of which occur in children. The overall crude hospitalisation rate by ACSC is 146.9/10,000 inhabitants (range: 12.4/10,000-239.9/10,000). SHR ranges from 0.01 to 1.85. "Hospital admissions due to ACSC" is a valid indicator to assess global performance of Primary Health Care and it identifies a part of hospital activity that is amenable to be cared for at Primary Health Care level and therefore potentially avoidable.

Aging properties of Kodak type 101 emulsions

Aging tests for several batches of Kodak type 101 emulsion show that storage conditions significantly influence how well the film will maintain its sensitometric properties, with sensitivity and density increasing to a maximum during this period. Any further aging may result in higher fog levels and sensitivity loss. It is noted that storage in an environment free of photographically active compounds allows film property optimization, and that film batches with different sensitivities age differently. Emulsions with maximum 1700-A sensitivity are 2.5 times faster than those at the low end of the sensitivity scale. These sensitive emulsions exhibit significantly accelerated changes in aging properties. Their use in space applications requires careful consideration of time and temperature profiles, encouraging the use of less sensitive emulsions when the controllability of these factors is limited.

Improving the quality of pressure ulcer care with prevention: a cost-effectiveness analysis.

2011-04-01

In October 2008, Centers for Medicare and Medicaid Services discontinued reimbursement for hospital-acquired pressure ulcers (HAPUs), thus placing stress on hospitals to prevent incidence of this costly condition. To evaluate whether prevention methods are cost-effective compared with standard care in the management of HAPUs. A semi-Markov model simulated the admission of patients to an acute care hospital from the time of admission through 1 year using the societal perspective. The model simulated health states that could potentially lead to an HAPU through either the practice of "prevention" or "standard care." Univariate sensitivity analyses, threshold analyses, and Bayesian multivariate probabilistic sensitivity analysis using 10,000 Monte Carlo simulations were conducted. Cost per quality-adjusted life-years (QALYs) gained for the prevention of HAPUs. Prevention was cost saving and resulted in greater expected effectiveness compared with the standard care approach per hospitalization. The expected cost of prevention was $7276.35, and the expected effectiveness was 11.241 QALYs. The expected cost for standard care was $10,053.95, and the expected effectiveness was 9.342 QALYs. The multivariate probabilistic sensitivity analysis showed that prevention resulted in cost savings in 99.99% of the simulations. The threshold cost of prevention was $821.53 per day per person, whereas the cost of prevention was estimated to be $54.66 per day per person. This study suggests that it is more cost effective to pay for prevention of HAPUs compared with standard care. Continuous preventive care of HAPUs in acutely ill patients could potentially reduce incidence and prevalence, as well as lead to lower expenditures.

Development and Implementation of a Pediatric Palliative Care Program in a Developing Country.

PubMed

Doherty, Megan; Thabet, Chloé

2018-01-01

Palliative care is recognized as an important component of care for children with cancer and other life-limiting conditions. In resource limited settings, palliative care is a key component of care for children with cancer and other life-limiting conditions. Globally, 98% of children who need palliative care live in low- or middle-income countries, where there are very few palliative care services available. There is limited evidence describing the practical considerations for the development and implementation of sustainable and cost-effective palliative care services in developing countries. Our aim is to describe the key considerations and initiatives that were successful in planning and implementing a hospital-based pediatric palliative care service specifically designed for a resource-limited setting. Bangabandu Sheikh Mujib Medical University (BSMMU) is a tertiary referral hospital in Bangladesh. Local palliative care services are very limited and focused on adult patients. In partnership with World Child Cancer, a project establishing a pediatric palliative care service was developed for children with cancer at BSMMU. We describe four key elements which were crucial for the success of this program: (1) raising awareness and sensitizing hospital administrators and clinical staff about pediatric palliative care; (2) providing education and training on pediatric palliative care for clinical staff; (3) forming a pediatric palliative care team; and (4) collecting data to characterize the need for pediatric palliative care. This model of a hospital-based pediatric palliative care service can be replicated in other resource-limited settings and can be expanded to include children with other life-limiting conditions. The development of pilot programs can generate interest among local physicians to become trained in pediatric palliative care and can be used to advocate for the palliative care needs of children.

A detailed family health history is currently the most potentially useful tool for diagnosis and risk assessment in clinical genetics. We developed and evaluated the usability and analytic validity of a patient-driven web-based family health history collection and analysis tool. Health Heritage(©) guides users through the collection of their family health history by relative, generates a pedigree, completes risk assessment, stratification, and recommendations for 89 conditions. We compared the performance of Health Heritage to that of Usual Care using a nonrandomized cohort trial of 109 volunteers. We contrasted the completeness and sensitivity of family health history collection and risk assessments derived from Health Heritage and Usual Care to those obtained by genetic counselors and genetic assessment teams. Nearly half (42%) of the Health Heritage participants reported discovery of health risks; 63% found the information easy to understand and 56% indicated it would change their health behavior. Health Heritage consistently outperformed Usual Care in the completeness and accuracy of family health history collection, identifying 60% of the elevated risk conditions specified by the genetic team versus 24% identified by Usual Care. Health Heritage also had greater sensitivity than Usual Care when comparing the identification of risks. These results suggest a strong role for automated family health history collection and risk assessment and underscore the potential of these data to serve as the foundation for comprehensive, cost-effective personalized genomic medicine.

Team functioning as a predictor of patient outcomes in early medical home implementation.

PubMed

Wu, Frances M; Rubenstein, Lisa V; Yoon, Jean

New models of patient-centered primary care such as the patient-centered medical home (PCMH) depend on high levels of interdisciplinary primary care team functioning to achieve improved outcomes. A few studies have qualitatively assessed barriers and facilitators to optimal team functioning; however, we know of no prior study that assesses PCMH team functioning in relationship to patient health outcomes. The aim of the study was to assess the relationships between primary care team functioning, patients' use of acute care, and mortality. Retrospective longitudinal cohort analysis of patient outcomes measured at two time points (2012 and 2013) after PCMH implementation began in Veterans Health Administration practices. Multilevel models examined practice-level measures of team functioning in relationship to patient outcomes (all-cause and ambulatory care-sensitive condition-related hospitalizations, emergency department visits, and mortality). We controlled for practice-level factors likely to affect team functioning, including leadership support, provider and staff burnout, and staffing sufficiency, as well as for individual patient characteristics. We also tested the model among a subgroup of vulnerable patients (homeless, mentally ill, or with dementia). In adjusted analyses, higher team functioning was associated with lower mortality (OR = 0.92, p = .04) among all patients and with fewer all-cause admissions (incidence rate ratio [IRR] = 0.90, p < 0.01), ambulatory care-sensitive condition-related admissions (IRR = 0.91, p = .04), and emergency department visits (IRR = 0.91, p = .03) in the vulnerable patient subgroup. These early findings give support for the importance of team functioning within PCMH models for achieving improved patient outcomes. A focus on team functioning is important especially in the early implementation of team-based primary care models.

The Cues and Care Trial: A randomized controlled trial of an intervention to reduce maternal anxiety and improve developmental outcomes in very low birthweight infants

Background Very low birthweight infants are at risk for deficits in cognitive and language development, as well as attention and behaviour problems. Maternal sensitive behaviour (i.e. awareness of infant cues and appropriate responsiveness to those cues) in interaction with her very low birthweight infant is associated with better outcomes in these domains; however, maternal anxiety interferes with the mother's ability to interact sensitively with her very low birthweight infant. There is a need for brief, cost-effective and timely interventions that address both maternal psychological distress and interactive behaviour. The Cues and Care trial is a randomized controlled trial of an intervention designed to reduce maternal anxiety and promote sensitive interaction in mothers of very low birthweight infants. Methods and design Mothers of singleton infants born at weights below 1500 g are recruited in the neonatal intensive care units of 2 tertiary care hospitals, and are randomly assigned to the experimental (Cues) intervention or to an attention control (Care) condition. The Cues intervention teaches mothers to attend to their own physiological, cognitive, and emotional cues that signal anxiety and worry, and to use cognitive-behavioural strategies to reduce distress. Mothers are also taught to understand infant cues and to respond sensitively to those cues. Mothers in the Care group receive general information about infant care. Both groups have 6 contacts with a trained intervener; 5 of the 6 sessions take place during the infant's hospitalization, and the sixth contact occurs after discharge, in the participant mother's home. The primary outcome is maternal symptoms of anxiety, assessed via self-report questionnaire immediately post-intervention. Secondary outcomes include maternal sensitive behaviour, maternal symptoms of posttraumatic stress, and infant development at 6 months corrected age. Discussion The Cues and Care trial will provide important information on the efficacy of a brief, skills-based intervention to reduce anxiety and increase sensitivity in mothers of very low birthweight infants. A brief intervention of this nature may be more readily implemented as part of standard neonatal intensive care than broad-based, multi-component interventions. By intervening early, we aim to optimize developmental outcomes in these high risk infants.

Background Brazil has the largest public health-system in the world, with 120 million people covered by its free primary care services. The Family Health Strategy (FHS) is the main primary care model, but there is no consensus on its impact on health outcomes. We systematically reviewed published evidence regarding the impact of the Brazilian FHS on selective primary care sensitive conditions (PCSC). Methods We searched Medline, Web of Science and Lilacs in May 2016 using key words in Portuguese and English, without language restriction. We included studies if intervention was the FHS; comparison was either different levels of FHS coverage or other primary health care service models; outcomes were the selected PCSC; and results were adjusted for relevant sanitary and socioeconomic variables, including the national conditional cash transfer program (Bolsa Familia). Due to differences in methods and outcomes reported, pooling of results was not possible. Results Of 1831 records found, 31 met our inclusion criteria. Of these, 25 were ecological studies. Twenty-one employed longitudinal quasi-experimental methods, 27 compared different levels the FHS coverage, whilst four compared the FHS versus other models of primary care. Fourteen studies found an association between higher FHS coverage and lower post-neonatal and child mortality. When the effect of Bolsa Familia was accounted for, the effect of the FHS on child mortality was greater. In 13 studies about hospitalizations due to PCSC, no clear pattern of association was found. In four studies, there was no effect on child and elderly vaccination or low-birth weight. No included studies addressed breast-feeding, dengue, HIV/AIDS and other neglected infectious diseases. Conclusions Among these ecological studies with limited quality evidence, increasing coverage by the FHS was consistently associated with improvements in child mortality. Scarce evidence on other health outcomes, hospitalization and synergies with cash transfer was found. PMID:28786997

Malign neglect: assessing older women's health care experiences in prison.

Aday, Ronald; Farney, Lori

2014-09-01

The problem of providing mandated medical care has become commonplace as correctional systems in the United States struggle to manage unprecedented increases in its aging prison population. This study explores older incarcerated women's perceptions of prison health care policies and their day-to-day survival experiences. Aggregate data obtained from a sample of 327 older women (mean age = 56) residing in prison facilities in five Southern states were used to identify a baseline of health conditions and needs for this vulnerable group. With an average of 4.2 chronic health conditions, frequently histories of victimization, and high rates of mental health issues, the women's experiences of negotiating health care was particularly challenging. By incorporating the voices of older women, we expose the contradictions, dilemmas, and obstacles they experience in their attempts to obtain health care. It is clear from the personal accounts shared that, despite court mandates, penal harm practices such as delaying or denying medical treatment as well as occasional staff indifferences are common in women's prisons. With older women having the greatest need for health care, an age- and gender-sensitive approach is recommended.

2012-01-01

Background The test characteristics of head circumference (HC) measurement percentile criteria for the identification of previously undetected pathology associated with head enlargement in primary care are unknown. Methods Electronic patient records were reviewed to identify children age 3 days to 3 years with new diagnoses of intracranial expansive conditions (IEC) and metabolic and genetic conditions associated with macrocephaly (MGCM). We tested the following HC percentile threshold criteria: ever above the 95th, 97th, or 99.6th percentile and ever crossing 2, 4, or 6 increasing major percentile lines. The Centers for Disease Control and World Health Organization growth curves were used, as well as the primary care network (PCN) curves previously derived from this cohort. Results Among 74,428 subjects, 85 (0.11%) had a new diagnosis of IEC (n = 56) or MGCM (n = 29), and between these 2 groups, 24 received intervention. The 99.6th percentile of the PCN curve was the only threshold with a PPV over 1% (PPV 1.8%); the sensitivity of this threshold was only 15%. Test characteristics for the 95th percentiles were: sensitivity (CDC: 46%; WHO: 55%; PCN: 40%), positive predictive value (PPV: CDC: 0.3%; WHO: 0.3%; PCN: 0.4%), and likelihood ratios positive (LR+: CDC: 2.8; WHO: 2.2; PCN: 3.9). Test characteristics for the 97th percentiles were: sensitivity (CDC: 40%; WHO: 48%; PCN: 34%), PPV (CDC: 0.4%; WHO: 0.3%; PCN: 0.6%), and LR+ (CDC: 3.6; WHO: 2.7; PCN: 5.6). Test characteristics for crossing 2 increasing major percentile lines were: sensitivity (CDC: 60%; WHO: 40%; PCN: 31%), PPV (CDC: 0.2%; WHO: 0.1%; PCN: 0.2%), and LR+ (CDC: 1.3; WHO: 1.1; PCN: 1.5). Conclusions Commonly used HC percentile thresholds had low sensitivity and low positive predictive value for diagnosing new pathology associated with head enlargement in children in a primary care network.

Poor continuity of care may contribute to high health care spending and adverse patient outcomes in dementia. To examine the association between medical clinician continuity and health care utilization, testing, and spending in older adults with dementia. This was a study of an observational retrospective cohort from the 2012 national sample in fee-for-service Medicare, conducted from July to December 2015, using inverse probability weighted analysis. A total of 1 416 369 continuously enrolled, community-dwelling, fee-for-service Medicare beneficiaries 65 years or older with a claims-based dementia diagnosis and at least 4 ambulatory visits in 2012 were included. Continuity of care score measured on patient visits across physicians over 12 months. A higher continuity score is assigned to visit patterns in which a larger share of the patient's total visits are with fewer clinicians. Score range from 0 to 1 was examined in low-, medium-, and high-continuity tertiles. Outcomes include all-cause hospitalization, ambulatory care sensitive condition hospitalization, emergency department visit, imaging, and laboratory testing (computed tomographic [CT] scan of the head, chest radiography, urinalysis, and urine culture), and health care spending (overall, hospital and skilled nursing facility, and physician). Beneficiaries with dementia who had lower levels of continuity of care were younger, had a higher income, and had more comorbid medical conditions. Almost 50% of patients had at least 1 hospitalization and emergency department visit during the year. Utilization was lower with increasing level of continuity. Specifically comparing the highest- vs lowest-continuity groups, annual rates per beneficiary of hospitalization (0.83 vs 0.88), emergency department visits (0.84 vs 0.99), CT scan of the head (0.71 vs 0.83), urinalysis (0.72 vs 1.09), and health care spending (total spending, $22 004 vs $24 371) were higher with lower continuity even after accounting for sociodemographic factors and comorbidity burden (P < .001 for all comparisons). The rate of ambulatory care sensitive condition hospitalization was similar across continuity groups. Among older fee-for-service Medicare beneficiaries with a dementia diagnosis, lower continuity of care is associated with higher rates of hospitalization, emergency department visits, testing, and health care spending. Further research into these relationships, including potentially relevant clinical, clinician, and systems factors, can inform whether improving continuity of care in this population may benefit patients and the wider health system.

2016-01-01

Objectives: describe care needs and demands that mark the discursive practices of ostomized clients and family members and discuss guidelines for a comprehensive care program to ostomized clients and their families, organized by macrosociological categories. Method: Creative and Sensitive, involving 17 ostomized subjects and family members at a municipal outpatient clinic. The ethical aspects were complied with. A characterization form was used, as well as Creativity and Sensitivity Dynamics: "speaking map", "body-knowledge" and "calendar". Critical Discourse Analysis was applied. Results: the health needs and care demands of the ostomized patients and their family members, in their multiple dimensions, were constituted in the home and community, outpatient and social context, implying new orientations for nursing care. The unveiling of the data brought elements that constituted guidelines, in a macrosociological approach, to achieve the expanded integrality of nursing care. Conclusion: the ostomized clients are unique in their genre/peculiar from Latin sui generis, calling for strategies that respond to and distinguish their specificities. Elaborating a Public Health Policy that improves and reorganizes the care demands, taking into account these individual biopsychosocial and spiritual aspects, is a possible and irrevocable target in the attempt to achieve better conditions of health and wellbeing.

2005-09-01

The impact of differences in maternal self-efficacy and infant difficulty on mothers' sensitivity to small changes in the fundamental frequency of an audiotaped infant's cry was explored in 2 experiments. The experiments share in common experimental manipulations of infant difficulty, a laboratory derived measure of maternal efficacy (low, moderate, and high illusory control), and the use of signal detection methodology to measure maternal sensory sensitivity. In Experiment 1 (N = 72), easy and difficult infant temperament was manipulated by varying the amount of crying (i.e., frequency of cry termination) in a simulated child-care task. In Experiment 2 (N = 51), easy and difficult infant temperament was manipulated via exposure to the solvable or unsolvable pretreatment of a learned helplessness task to mirror mothers' ability to soothe a crying infant. In both experiments, only mothers with high illusory control showed reduced sensory sensitivity under the difficult infant condition compared with the easy infant condition.

An emergency department (ED) visit may be a marker for limited access to primary medical care, particularly among those with ambulatory care sensitive chronic conditions (ACSCC). In a population with universal health insurance, to examine the relationships between primary care characteristics and location of last general physician (GP) contact (in an ED vs. elsewhere) among those with and without an ACSCC. A cross-sectional survey using data from 2 cycles of the Canadian Community Health Survey carried out in 2003 and 2005. The study sample comprised Québec residents aged ≥18 who reported at least one GP contact during the previous 12 months, and were not hospitalized (n = 33,491). The primary outcome was place of last GP contact: in an ED versus elsewhere. Independent variables included the following: lack of a regular physician, perceived unmet healthcare needs, perceived availability of health care, number of contacts with doctors and nurses, and diagnosis of an ACSCC (hypertension, heart disease, chronic respiratory disease, diabetes). Using multiple logistic regression, with adjustment for sociodemographic, health status, and health services variables, lack of a regular GP and perceptions of unmet needs were associated with last GP contact in an ED; there was no interaction with ACSCC or other chronic conditions. Primary care characteristics associated with GP contact in an ED rather than another site reflect individual characteristics (affiliation with a primary GP and perceived needs) rather than the geographic availability of healthcare, both among those with and without chronic conditions.

For measuring oral malodor in daily clinical practice and in field study, we developed and evaluated a highly sensitive portable monitor system. We examined sensitivity and specificity of the sensor for volatile sulfur compounds (VSC) and obstructive gases, such as ethanol, acetone, and acetaldehyde. Each mouth air provided by 46 people was measured by this monitor, gas chromatography (GC), and olfactory panel and compared with each other. Based on the result, we used the monitor for mass health examination of a rural town with standardized measuring. The sensor detected hydrogen sulfide, methyl mercaptan, and dimethyl sulfide with 10-1000 times higher sensitivity than the other gases. The monitor's specificity was significantly improved by a VSC-selective filter. There were significant correlations between VSC concentration by the sulfide monitor and by GC, and by organoleptic score. Thirty-six percent of 969 examinees had oral malodor in a rural town. Seventy-eight percent of 969 examinees were motivated to take care of their oral condition by oral malodor measuring with the monitor. The portable sulfide monitor was useful to promote oral health care not only in clinics, but also in field study. The simple and quick operation system and the standardized measuring make it one of parameters of oral condition.

Background Initiation of antiretroviral therapy (ART) in all HIV-infected adults, regardless of count, is a proposed strategy for reducing HIV transmission. We investigated the conditions under which starting ART early could entail more risks than benefits for patients with high CD4 counts. Methods We used a simulation model to compare ART initiation upon entry to care (“immediate ART”) to initiation at CD4 ≤350 cells/μL (“WHO 2010 ART”) in African adults with CD4 counts >500 cells/μL. We varied inputs to determine the combination of parameters (population characteristics, conditions of care, treatment outcomes) that would result in higher 15-year mortality with immediate ART. Results Fifteen-year mortality was 56.7% for WHO 2010 and 51.8% for immediate ART. In one-way sensitivity analysis, lower 15-year mortality was consistently achieved with immediate ART unless the rate of fatal ART toxicity was >1.0/100PY, the rate of withdrawal from care was >1.2-fold higher or the rate of ART failure due to poor adherence was >4.3-fold higher on immediate ART. In multi-way sensitivity analysis, immediate ART led to higher mortality when moderate rates of fatal ART toxicity (0.25/100PY) were combined with rates of withdrawal from care >1.1-fold higher and rates of treatment failure >2.1-fold higher on immediate ART than on WHO 2010 ART. Conclusions In sub-Saharan Africa, ART initiation at entry into care would improve long-term survival of patients with high CD4 counts, unless it is associated with increased withdrawal from care and decreased adherence. In early ART trials, a focus on retention and adherence will be critical. PMID:22809695

Medicare managed care plan performance: a comparison across hospitalization types.

Basu, Jayasree; Mobley, Lee Rivers

2012-01-01

The study evaluates the performance of Medicare managed care (Medicare Advantage [MA]) Plans in comparison to Medicare fee-for-service (FFS) Plans in three states with historically high Medicare managed care penetration (New York, California, Florida), in terms of lowering the risks of preventable or ambulatory care sensitive conditions (ACSC) hospital admissions and providing increased referrals for admissions for specialty procedures. Using 2004 hospital discharge files from the Healthcare Cost and Utilization Project (HCUP-SID) of the Agency for Healthcare Research and Quality, ACSC admissions are compared with 'marker' admissions and 'referral-sensitive' admissions, using a multinomial logistic regression approach. The year 2004 represents a strategic time to test the impact of MA on preventable hospitalizations, because the HMOs dominated the market composition in that time period. MA enrollees in California experienced 22% lower relative risk (RRR= 0.78, p<0.01), those in Florida experienced 16% lower relative risk (RRR= 0.84, p<0.01), while those in New York experienced 9% lower relative risk (RRR=0.91, p<0.01) of preventable (versus marker) admissions compared to their FFS counterparts. MA enrollees in New York experienced 37% higher relative risk (RRR=1.37, p<0.01) and those in Florida had 41% higher relative risk (RRR=1.41, p<0.01)-while MA enrollees in California had 13% lower relative risk (RRR=0.87, p<0.01)-of referral-sensitive (versus marker) admissions compared to their FFS counterparts. While MA plans were associated with reductions in preventable hospitalizations in all three states, the effects on referral-sensitive admissions varied, with California experiencing lower relative risk of referral-sensitive admissions for MA plan enrollees. The lower relative risk of preventable admissions for MA plan enrollees in New York and Florida became more pronounced after accounting for selection bias.

The aim of this study was to conduct a primary care validation study of a single screening question for alcohol misuse ("When was the last time you had more than X drinks in 1 day?," where X was four for women and X was five for men), which was previously validated in a study conducted in emergency departments. This cross-sectional study was accomplished by interviewing 625 male and female adult drinkers who presented to five southeastern primary care practices. Patients answered the single question (coded as within 3 months, within 12 months, ever, or never), Alcohol Use Disorders Identification Test (AUDIT), and AUDIT consumption questions (AUDIT-C). Alcohol misuse was defined as either at-risk drinking, identified by a 29-day Timeline Followback interview or a current (past-year) alcohol-use disorder by Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria, or both. Among 625 drinkers interviewed, 25.6% were at-risk drinkers, 21.7% had a current alcohol- use disorder, and 35.2% had either or both conditions. Considering "within the last 3 months" as positive, the sensitivity of the single question was 80% and the specificity was 74%. Chi-square analyses revealed similar sensitivity across ethnic and gender groups; however, specificity was higher in women and whites (p = .0187 and .0421, respectively). Considering "within the last 12 months" as positive increased the question's sensitivity, especially for those with alcohol-use disorders. The area under the receiver operating characteristic curve of the single alcohol screening question (0.79) was slightly lower than for the AUDIT and AUDIT-C, but sensitivity and specificity were similar. A single question about the last episode of heavy drinking is a sensitive, time-efficient screening instrument that shows promise for increasing alcohol screening in primary care practices.

Previous studies underscore the need to improve caregiver-child interactions in early child care centers. In this study we used a randomized controlled trial to examine whether a 5-week video feedback training can improve six key interactive skills of caregivers in early child care centers: Sensitive responsiveness, respect for autonomy, structuring and limit setting, verbal communication, developmental stimulation, and fostering positive peer interactions. A total of 139 caregivers from 68 early child care groups for 0- to 4-year-old children in Dutch child care centers participated in this RCT, 69 in the intervention condition and 70 in the control condition. Caregiver interactive skills during everyday interactions with the children were rated from videotape using the Caregiver Interaction Profile (CIP) scales at pretest, posttest, and follow-up 3 months after the posttest. Results at posttest indicate a significant positive training effect on all six caregiver interactive skills. Effect sizes of the CIP training range between d  = 0.35 and d  = 0.79. Three months after the posttest, caregivers in the intervention group still scored significantly higher on sensitive responsiveness, respect for autonomy, verbal communication, and fostering positive peer interactions than caregivers in the control group with effect sizes ranging between d  = 0.47 and d  = 0.70. This study shows that the quality of caregiver-child interactions can be improved for all six important caregiver skills, with a relatively short training program. Possible ways to further improve the training and to implement it in practice and education are discussed.

Invisible realities: Caring for older Moroccan migrants with dementia in Belgium.

The number of older Moroccan migrants reaching the age of high risk for dementia is increasing in Belgium. Yet no study has been performed to explore how Moroccan families facing dementia experience and manage the condition. The study employed a qualitative design using semi-structured interviews with 12 informal and 13 formal caregivers to answer this research question. Findings indicate that the experience of dementia includes several invisible realities that challenge the informal and formal caregivers: (1) the invisibility of dementia as a condition; (2) the invisible subtleties of the informal care execution; (3) the invisibility and inaccessibility of care services as explanation for these family's non-use of available services; and (4) the overlooking of culture, migration and religion as invisible influencers of the overall dementia experience. A better understanding of these hidden realities of migrant older people with dementia and their caregivers could lead to interventions to provide effective and tailored person-centred care that is sensitive to the individual's life experiences, culture and religious background.

Nanostructured Gas Sensors for Health Care: An Overview

2015-01-01

Nanostructured platforms have been utilized for fabrication of small, sensitive and reliable gas sensing devices owing to high functionality, enhanced charge transport and electro-catalytic property. As a result of globalization, rapid, sensitive and selective detection of gases in environment is essential for health care and security. Nonmaterial such as metal, metal oxides, organic polymers, and organic-inorganic hybrid nanocomposites exhibit interesting optical, electrical, magnetic and molecular properties, and hence are found potential gas sensing materials. Morphological, electrical, and optical properties of such nanostructures can be tailored via controlling the precursor concentration and synthesis conditions resulting to achieve desired sensing. This review presents applications of nano-enabling gas sensors to detect gases for environment monitoring. The recent update, challenges, and future vision for commercial applications of such sensor are also described here. PMID:26491544

The quality of clinical care can be reliably measured in multiple settings using standardised patients (SPs), but this methodology has not been extensively used in Sub-Saharan Africa. This study validates the use of SPs for a variety of tracer conditions in Nairobi, Kenya, and provides new results on the quality of care in sampled primary care clinics. We deployed 14 SPs in private and public clinics presenting either asthma, child diarrhoea, tuberculosis or unstable angina. Case management guidelines and checklists were jointly developed with the Ministry of Health. We validated the SP method based on the ability of SPs to avoid detection or dangerous situations, without imposing a substantial time burden on providers. We also evaluated the sensitivity of quality measures to SP characteristics. We assessed quality of practice through adherence to guidelines and checklists for the entire sample, stratified by case and stratified by sector, and in comparison with previously published results from urban India, rural India and rural China. Across 166 interactions in 42 facilities, detection rates and exposure to unsafe conditions were both zero. There were no detected outcome correlations with SP characteristics that would bias the results. Across all four conditions, 53% of SPs were correctly managed with wide variation across tracer conditions. SPs paid 76% less in public clinics, but proportions of correct management were similar to private clinics for three conditions and higher for the fourth. Kenyan outcomes compared favourably with India and China in all but the angina case. The SP method is safe and effective in the urban Kenyan setting for the assessment of clinical practice. The pilot results suggest that public providers in this setting provide similar rates of correct management to private providers at significantly lower out-of-pocket costs for patients. However, comparisons across countries are sensitive to the tracer condition considered.

Substantial proportions of US residents in the USA-Mexico border region cross into Mexico for health care; increases in violence in northern Mexico may have affected this access. We quantified associations between violence in Mexico and decreases in access to care for border county residents. We also examined associations between border county residence and access. We used hospital inpatient data for Arizona, California and Texas (2005-10) to estimate associations between homicide rates and the probability of hospitalization for ambulatory care sensitive (ACS) conditions. Hospitalizations for ACS conditions were compared with homicide rates in Mexican municipalities matched by patient residence. A 1 SD increase in the homicide rate of the nearest Mexican municipality was associated with a 2.2 percentage point increase in the probability of being hospitalized for an ACS condition for border county patients. Residence in a border county was associated with a 1.3 percentage point decrease in the probability of being hospitalized for an ACS condition. Increased homicide rates in Mexico were associated with increased hospitalizations for ACS conditions in the USA, although residence in a border county was associated with decreased probability of being hospitalized for an ACS condition. Expanding access in the border region may mitigate these effects by providing alternative sources of care. © The Author 2015.

To describe and compare population-level aspects of diabetes and diabetes primary care among people with and without intellectual and developmental disabilities. Administrative health data accessed from the Institute for Clinical Evaluative Sciences was used to identify a cohort of Ontarians with and without intellectual and developmental disabilities between the ages of 30 and 69 years (n = 28 567). These people were compared with a random sample of people without intellectual and developmental disabilities (n = 2 261 919) according to diabetes prevalence, incidence, age, sex, rurality, neighbourhood income and morbidity. To measure diabetes primary care, we also studied hospitalizations for diabetes-related ambulatory care-sensitive conditions. Adults with intellectual and developmental disabilities had a consistently higher prevalence and incidence of diabetes than those without intellectual and developmental disabilities. Disparities in prevalence between those with and without intellectual and developmental disabilities were most notable among women, younger adults and those residing in rural or high income neighbourhoods. In terms of hospitalizations for diabetes-related ambulatory care-sensitive conditions, people with intellectual and developmental disabilities were 2.6 times more likely to be hospitalized. Adults with intellectual and developmental disabilities are at high risk of developing and being hospitalized for diabetes. The findings of the present study have a number of important implications related to the early detection, prevention and proper management of diabetes among adults with intellectual and developmental disabilities. © 2014 The Authors.

Diverticular Disease in the Primary Care Setting.

PubMed

Wensaas, Knut-Arne; Hungin, Amrit Pali

2016-10-01

Diverticular disease is a chronic and common condition, and yet the impact of diverticular disease in primary care is largely unknown. The diagnosis of diverticular disease relies on the demonstration of diverticula in the colon, and the necessary investigations are often not available in primary care. The specificity and sensitivity of symptoms, clinical signs and laboratory tests alone are generally low and consequently the diagnostic process will be characterized by uncertainty. Also, the criteria for symptomatic uncomplicated diverticular disease in the absence of macroscopic inflammation are not clearly defined. Therefore both the prevalence of diverticular disease and the incidence of diverticulitis in primary care are unknown. Current recommendations for treatment and follow-up of patients with acute diverticulitis are based on studies where the diagnosis has been verified by computerized tomography. The results cannot be directly transferred to primary care where the diagnosis has to rely on the interpretation of symptoms and signs. Therefore, one must allow for greater diagnostic uncertainty, and safety netting in the event of unexpected development of the condition is an important aspect of the management of diverticulitis in primary care. The highest prevalence of diverticular disease is found among older patients, where multimorbidity and polypharmacy is common. The challenge is to remember the possible contribution of diverticular disease to the patient's overall condition and to foresee its implications in terms of advice and treatment in relation to other diseases.

Environmental Stability of Plasmonic Biosensors Based on Natural versus Artificial Antibody.

2018-06-13

Plasmonic biosensors based on the refractive index sensitivity of localized surface plasmon resonance (LSPR) are considered to be highly promising for on-chip and point-of-care biodiagnostics. However, most of the current plasmonic biosensors employ natural antibodies as biorecognition elements, which can easily lose their biorecognition ability upon exposure to environmental stressors (e.g., temperature and humidity). Plasmonic biosensors relying on molecular imprints as recognition elements (artificial antibodies) are hypothesized to be an attractive alternative for applications in resource-limited settings due to their excellent thermal, chemical, and environmental stability. In this work, we provide a comprehensive comparison of the stability of plasmonic biosensors based on natural and artificial antibodies. Although the natural antibody-based plasmonic biosensors exhibit superior sensitivity, their stability (temporal, thermal, and chemical) was found to be vastly inferior to those based on artificial antibodies. Our results convincingly demonstrate that these novel classes of artificial antibody-based plasmonic biosensors are highly attractive for point-of-care and resource-limited conditions where tight control over transport, storage, and handling conditions is not possible.

To examine how medical complexity modifies the relationship between enrollment in Department of Veterans Affairs (VA) home-based primary care (HBPC) and hospitalization for ambulatory care-sensitive conditions (ACSC) for veterans with diabetes mellitus and whether the effect of HBPC on hospitalizations varies according to clinical condition. Retrospective cohort study. VA and non-VA hospitals. VA beneficiaries aged 67 and older with diabetes mellitus and enrolled in Medicare (N = 364,972). Instrumental variables regression models were used to estimate the effect of HBPC enrollment on hospitalization for ACSCs (defined according to the Agency for Healthcare Research and Quality Prevention Quality Indicators) overall and in subgroups stratified according to medical complexity. Models were also estimated for each ACSC to determine which conditions were most sensitive to HBPC. Distance from the veteran's residence to the nearest HBPC site was used as the instrumental variable. HBPC was associated with fewer ACSC hospitalizations (odds ratio (OR) = 0.35 per person-month, 95% confidence interval (CI) = 0.30-0.42). For veterans in the highest quartile of medical complexity, HBPC enrollment was associated with fewer ACSC hospitalizations (OR = 0.43, 95% CI = 0.19-0.93), whereas for those in the lowest quartile, HBPC was associated with more ACSC hospitalizations (OR = 33.2, 95% CI = 4.6-240.1). HBPC enrollment was associated with fewer hospitalizations for a range of ACSCs. HBPC enrollment was associated with fewer hospitalizations for a range of ACSCs in veterans with diabetes mellitus but only in the most medically complex individuals. This demonstrates the importance of appropriate targeting and suggests that the effect of HBPC is attributable to its comprehensive approach rather than condition-specific interventions.

2012-10-01

We investigated the size profile of US primary care and behavioral health physician practices since size may impact the ability to institute care management processes (CMPs) that can enhance care quality. We utilized 2009 claims data from a nationwide commercial insurer to estimate practice size by linking providers by tax identification number. We determined the proportion of primary care physicians, psychiatrists, and behavioral health providers practicing in venues of >20 providers per practice (the lower bound for current CMP practice surveys). Among primary care physicians (n=350,350), only 2.1% of practices consisted of >20 providers. Among behavioral health practitioners (n=146,992) and psychiatrists (n=44,449), 1.3% and 1.0% of practices, respectively, had >20 providers. Sensitivity analysis excluding single-physician practices as "secondary" confirmed findings, with primary care and psychiatrist practices of >20 providers comprising, respectively, only 19.4% and 8.8% of practices (difference: P<0.0001). In secondary analyses, bipolar disorder was used as a tracer condition to estimate practice census for a high-complexity, high-cost behavioral health condition; only 1.3-18 patients per practice had claims for this condition. The tax identification number method for estimating practice size has strengths and limitations that complement those of survey methods. The proportion of practices below the lower bound of prior CMP studies is substantial, and care models and policies will need to address the needs of such practices and their patients. Achieving a critical mass of patients for disorder-specific CMPs will require coordination across multiple small practices.

Assessment of access to primary health care among children and adolescents hospitalized due to avoidable conditions.

Hospitalizations for ambulatory care-sensitive conditions (HACSC) are considered an indicator of the effectiveness of primary health care (PHC). High rates of HACSC represent problems in the access or the quality of health care. In Brazil, HACSC rates are high and there are few studies on the factors associated with it. To evaluate the access to PHC offered to children and adolescents hospitalized due to ACSC and analyze the conditioning factors. Cross-sectional study with a quantitative and qualitative approach. Five hundred and one (501) users (guardians/caregivers) and 42 professionals of PHC units were interviewed over one year. Quantitative data were obtained using Primary Care Assessment Tool validated in Brazil (PCATool-Brazil), while qualitative data were collected by semi-structured interview. The independent variables were: age, maternal education, family income, type of diagnosis, and model of care offered, and the dependent variables were access and its components (accessibility and use of services). Sixty-five percent (65.2%) of hospitalizations were ACSC. From the perspective of both users and professionals, access and its components presented low scores. Age, type of diagnosis, and model of care affected the results. The proportion of HACSC was high in this population. Access to services is inappropriate due to: barriers to access, appreciation of the emergency services, and attitude towards health needs. Professional attitudes and opinions reinforce inadequate ideas of users reflecting on the pattern of service use.

Quality of life in old age - a concept analysis.

To identify existing definitions of quality of life in old age and to determine the most suitable for evaluating outcomes of nursing care for older adults. Promoting quality of life is a central concern of nursing care for older persons. There is, however, a lack of clarity about the meaning of this concept. Attributes of quality of life are often confused with those factors influencing them. Concept analysis according to Walker and Avant. A search was carried out in the databases MEDLINE, Cumulative Index to Nursing and Allied Health Literature, PsycINFO(®) and Gerolit for the years 1992-2013. Excerpts dealing with definitions, antecedents, consequences and empirical referents of the concept were compiled. Three basic concepts for quality of life were identified: satisfying life conditions, subjective general well-being and subjective fulfilment of dimensions of human life. Satisfying life conditions are antecedent to the other concepts. It is not suitable to view such conditions as an outcome of nursing care for older adults because an outcome has to be a consequence. General well-being is likely to remain stable over time and changing conditions due to adaptation taking place. Fulfilment of dimensions of human life as a multidimensional inner state may be more sensitive to changing conditions. Fulfilment of dimensions of human life is the most suitable definition of quality of life in old age as an outcome of nursing care. Studies are needed to decide whether it is responsive to changing circumstances. Fulfilment of dimensions of human life should be assessed to provide care that meets the needs of clients. © 2015 John Wiley & Sons Ltd.

A patient undergoing surgery may receive anesthesia care from several anesthesia providers. The safety of anesthesia care transitions has not been evaluated. Using unconditional and conditional multivariable logistic regression models, we tested whether the number of attending anesthesiologists involved in an operation was associated with postoperative complications. In a cohort of patients undergoing elective colorectal surgical in an academic tertiary care center with a stable anesthesia care team model participating in the American College of Surgeons National Surgical Quality Improvement Program, using unconditional and conditional multivariable logistic regression models, we tested adjusted associations between numbers of attending anesthesiologists and occurrence of death or a major complication (acute renal failure, bleeding that required a transfusion of 4 units or more of red blood cells within 72 hours after surgery, cardiac arrest requiring cardiopulmonary resuscitation, coma of 24 hours or longer, myocardial infarction, unplanned intubation, ventilator use for 48 hours or more, pneumonia, stroke, wound disruption, deep or organ-space surgical-site infection, superficial surgical-site infection, sepsis, septic shock, systemic inflammatory response syndrome). We identified 927 patients who underwent elective colectomy of comparable surgical intensity. In all, 71 (7.7%) patients had major nonfatal complications or death. One anesthesiologist provided care for 530 (57%) patients, 2 anesthesiologists for 287 (31%), and 3 or more for 110 (12%). The number of attending anesthesiologists was associated with increased odds of postoperative complication (unadjusted odds ratio [OR] = 1.52, 95% confidence interval [CI] 1.18-1.96, P = 0.0013; adjusted OR = 1.44, 95% CI 1.09-1.91, P = 0.0106). In sensitivity analyses, occurrence of a complication was significantly associated with the number of in-room providers, defined as anesthesia residents and nurse anesthetists (adjusted OR = 1.39, 95% CI 1.01-1.92, P = 0.0446) and for all anesthesia providers (adjusted OR = 1.58, 95%CI 1.20-2.08, P = 0.0012). Findings persisted across multiple, alternative adjustments, sensitivity analyses, and conditional logistic regression with matching on operative duration. In our study, care by additional attending anesthesiologists and in-room providers was independently associated with an increased odds of postoperative complications. These findings challenge the assumption that anesthesia transitions are care neutral and not contributory to surgical outcomes.

Better communication among field health care teams and points of care, together with investments focused on improving teamwork, individual management, and clinical skills, are strategies for achieving better outcomes in patient-oriented care. This research aims to implement and evaluate interventions focused on improving communication and knowledge among health teams based on points of care in a regional public health outreach network, assessing the following hypotheses: 1) A better-working communication process between hospitals and primary health care providers can improve the sharing of information on patients as well as patients' outcomes. 2) A skill-upgrading education tool offered to health providers at their work sites can improve patients' care and outcomes. A quasi-experimental study protocol with a mixed-methods approach (quantitative and qualitative) was developed to evaluate communication tools for health care professionals based in primary care units and in a general hospital in the southern region of São Paulo City, Brazil. The usefulness and implementation processes of the integration strategies will be evaluated, considering: 1) An Internet-based communication platform that facilitates continuity and integrality of care to patients, and 2) A tailored updating distance-learning course on ambulatory care sensitive conditions for clinical skills improvements. The observational study will evaluate a non-randomized cohort of adult patients, with historical controls. Hospitalized patients diagnosed with an ambulatory care sensitive condition will be selected and followed for 1 year after hospital discharge. Data will be collected using validated questionnaires and from patients' medical records. Health care professionals will be evaluated related to their use of education and communication tools and their demographic and psychological profiles. The primary outcome measured will be the patients' 30-day hospital readmission rates. A sample size of 560 patients was calculated to fit a valid logistic model. In addition, qualitative approaches will be used to identify subjective perceptions of providers about the implementation process and of patients about health system use. This research project will gather relevant information about implementation processes for education and communication tools and their impact on human resources training, rates of readmission, and patient-related outcomes.

Patient-centered culturally sensitive health care (PC-CSHC) is a best practice approach for improving health-care delivery to culturally diverse populations and reducing health disparities. Despite patients' report that cultural sensitivity by health-care office staff is an important aspect of PC-CSHC, the majority of available research on PC-CSHC focuses exclusively on health-care providers. This may be due in part to the paucity of instruments available to assess the cultural sensitivity of health-care office staff. The objective of the present study is to determine the psychometric properties of the Tucker-Culturally Sensitive Health Care Office Staff Inventory-Self-Assessment Form (T-CSHCOSI-SAF). This instrument is designed to enable health-care office staff to self-assess their level of agreement that they display behaviors and attitudes that culturally diverse patients have identified as office staff cultural sensitivity indicators. A sample of 510 health-care office staff were recruited at 67 health-care sites across the United States. These health-care office staff anonymously completed the T-CSHCOSI-SAF and a demographic data questionnaire. Confirmatory factor analyses of the T-CSHCOSI-SAF revealed that this inventory has 2 factors with high internal consistency reliability (Cronbach's αs= .916 and .912). The T-CSHCOSI-SAF is a useful inventory for health-care office staff to assess their own level of patient-centered cultural sensitivity. Such self-assessment data can be used in the development and implementation of trainings to promote patient-centered cultural sensitivity of health-care office staff and to help draw the attention of these staff to displaying patient-centered cultural sensitivity.

The objective of this study was to develop and validate a subject-specific framework for modelling the human foot. This was achieved by integrating medical image-based finite element modelling, individualised multi-body musculoskeletal modelling and 3D gait measurements. A 3D ankle-foot finite element model comprising all major foot structures was constructed based on MRI of one individual. A multi-body musculoskeletal model and 3D gait measurements for the same subject were used to define loading and boundary conditions. Sensitivity analyses were used to investigate the effects of key modelling parameters on model predictions. Prediction errors of average and peak plantar pressures were below 10% in all ten plantar regions at five key gait events with only one exception (lateral heel, in early stance, error of 14.44%). The sensitivity analyses results suggest that predictions of peak plantar pressures are moderately sensitive to material properties, ground reaction forces and muscle forces, and significantly sensitive to foot orientation. The maximum region-specific percentage change ratios (peak stress percentage change over parameter percentage change) were 1.935-2.258 for ground reaction forces, 1.528-2.727 for plantar flexor muscles and 4.84-11.37 for foot orientations. This strongly suggests that loading and boundary conditions need to be very carefully defined based on personalised measurement data.

Admissions for ambulatory care sensitive conditions (ACSCs) are considered preventable and indicators of poor access to primary care. We wondered whether per-capita rates of admission for ACSCs in France demonstrated geographic variation, were changing, were related to other independent variables, or were comparable to those in other countries; further, we wanted to quantify the resources such admissions consume. We calculated per-capita rates of admission for five categories (chronic, acute, vaccination preventable, alcohol-related, and other) of ACSCs in 94 departments in mainland France in 2009 and 2010, examined measures and causes of geographic variation in those rates, computed the costs of those admissions, and compared rates of admission for ACSCs in France to those in several other countries. The highest ACSC admission rates generally occurred in the young and the old, but rates varied across French regions. Over the 2-year period, rates of most categories of ACSCs increased; higher ACSC admission rates were associated with lower incomes and a higher supply of hospital beds. We found that the local supply of general practitioners was inversely associated with rates of chronic and total ACSC admission rates, but that this relationship disappeared if we accounted for patients' use of general practitioners in neighboring departments. ACSC admissions cost 4.755 billion euros in 2009 and 5.066 billion euros in 2010; they consumed 7.86 and 8.74 million bed days of care, respectively. France had higher rates of ACSC admissions than most other countries examined. Because admissions for ACSCs are generally considered a failure of outpatient care, cost French taxpayers substantial monetary and hospital resources, and appear to occur more frequently in France than in other countries, policymakers should prioritize targeted efforts to reduce them.

The objective was to analyze whether socioeconomic factors related to the context and those related to the model of care-specifically the coverage of primary care by the Family Health Strategy (ESF)-had an impact on hospitalizations due to heart failure (HF) and stroke, in the State of São Paulo/Brazil between 1998 and 2013. A longitudinal ecological study involving 645 municipalities was conducted in the state of São Paulo/Brazil from 1998 to 2013, using the Hospital Information System (SIH-DataSUS database). The hospitalizations for primary care sensitive conditions: Stroke and heart failure (HF) that correspond to the International Classification of Diseases (ICD 10): I50, I63 to I67; I69, G45 to G46 were analyzed longitudinally during the period indicated regarding the percentage of people covered by the Family Health Program (PSF) adjusted for confounders (population size, gross domestic product -GDP and human development index- HDI). There was a significant decrease in the number of hospitalizations for heart failure and stroke per 10000 (inhabitants) in the period (p <0.0001), with a significant relationship with increased proportion of ESF (p <0.0001), and this remained significant even when possible confounders (population size, GDP and HDI) were included in the model (p <0.0001). GDP per capita was close to or higher than that if many European countries, which shows the relevance of the study. The health care model based on the Family Health Strategy positively impacted hospitalization indicators for heart failure and stroke, indicating that this model is effective in the prevention of primary care sensitive conditions.

The objectives of this paper are two-fold. First, a numerical scheme for the simulation of a buoyant, reacting jet is presented with special attention given to boundary conditions. In the absence of coflow, a jet flame is particularly sensitive to boundary conditions enforced upon the computational domain. However, careful consideration of proper boundary conditions can minimize their effect upon the overall simulation. Second, results of some preliminary simulations are presented over a range of Froude and Damkohler numbers. This range was chosen so as to produce lifted flames in both normal gravity and microgravity environments.

A culturally sensitive educational intervention that encouraged sun protection behaviors among kidney transplant recipients was developed and the short-term efficacy was evaluated. Non-Hispanic White, Hispanic/Latino, and non-Hispanic Black patients, who received a transplant 2–24 months prior to the study, were randomized into two study groups: intervention versus standard of care. Electronic reminders tailored to the weather conditions were sent every two weeks by text message or email. Self-reported surveys and biologic measurements were obtained prior to the intervention and six weeks later. Among the 101 study participants, there was a statistically significant increase in knowledge, recognition of personal risk of developing skin cancer, willingness to change sun protection behavior, and self-reported performance of sun protection in participants receiving the intervention in comparison with those receiving standard of care (p <0.05). The pigment darkening of the sun–exposed forearm and sun damage of the forearm and sunburns/ skin irritation from the sun were significantly less in participants receiving the intervention (p <0.05). Providing sun protection education at the beginning of summer with reminders tailored to weather conditions helped KTRs adopt sun protection practices. This sun protection program for KTRs may be incorporated into the care provided by the nephrologist or transplant surgeon. PMID:25395386

Information about the extent and dynamics of the West Antarctic Ice Sheet during past glaciations is preserved inside ice sheets themselves. Ice cores are capable of retrieving information about glacial history, but they are spatially sparse. Ice-penetrating radar, on the other hand, has been used to map large areas of the West Antarctic Ice Sheet and can be correlated to ice core chronologies. Englacial isochronous layers observed in ice-penetrating radar are the result of variations in ice composition, fabric, temperature and other factors. The shape of these isochronous surfaces is expected to encode information about past and present boundary conditions and ice dynamics. Dipping of englacial layers, for example, may reveal the presence of rapid ice flow through paleo ice streams or high geothermal heat flux. These layers therefore present a useful testbed for hypotheses about paleo ice sheet conditions. However, hypothesis testing requires careful consideration of the sensitivity of layer shape to the competing forces of ice sheet boundary conditions and ice dynamics over time. Controlled sensitivity tests are best completed using models, however ice sheet models generally do not have the capability of simulating layers in the presence of realistic boundary conditions. As such, modeling 3D englacial layers for comparison to observations is difficult and requires determination of a 3D ice velocity field. We present a method of post-processing simulated 3D ice sheet velocities into englacial isochronous layers using an advection scheme. We then test the sensitivity of layer geometry to uncertain boundary conditions, including heterogeneous subglacial geothermal flux and bedrock topography. By identifying areas of the ice sheet strongly influenced by boundary conditions, it may be possible to isolate the signature of paleo ice dynamics in the West Antarctic ice sheet.

The diagnostic accuracy of the MyDiagnostick to detect atrial fibrillation in primary care

PubMed Central

2014-01-01

Background Atrial fibrillation is very common in people aged 65 or older. This condition increases the risk of death, congestive heart failure and thromboembolic conditions. Many patients with atrial fibrillation are asymptomatic and a cerebrovascular accident (CVA) is often the first clinical presentation. Guidelines concerning the prevention of CVA recommend monitoring the heart rate in patients aged 65 or older. Recently, the MyDiagnostick (Applied Biomedical Systems BV, Maastricht, The Netherlands) was introduced as a new screening tool which might serve as an alternative for the less accurate pulse palpation. This study was designed to explore the diagnostic accuracy of the MyDiagnostick for the detection of atrial fibrillation. Methods A phase II diagnostic accuracy study in a convenience sample of 191 subjects recruited in primary care. The majority of participants were patients with a known history of atrial fibrillation (n = 161). Readings of the MyDiagnostick were compared with electrocardiographic recordings. Sensitivity and specificity and their 95% confidence interval were calculated using 2x2 tables. Results A prevalence of 54% for an atrial fibrillation rhythm was found in the study population at the moment of the study. A combination of three measurements with the MyDiagnostick for each patient showed a sensitivity of 94% (95% CI 87 – 98) and a specificity of 93% (95% CI 85 – 97). Conclusion The MyDiagnostick is an easy-to-use device that showed a good diagnostic accuracy with a high sensitivity and specificity for atrial fibrillation in a convenience sample in primary care. Future research is needed to determine the place of the MyDiagnostick in possible screening or case-finding strategies for atrial fibrillation. PMID:24913608

Breaking bad medical news in a dental care setting.

Dental care providers may diagnose diseases and conditions that affect a patient's general health. The authors reviewed issues related to breaking bad medical news to dental practice patients and provide guidance to clinicians about how to do so. To help reduce the potentially negative effects associated with emotionally laden communication with patients about serious health care findings, the authors present suggestions for appropriately and sensitively delivering bad medical news to both patients and their families in a supportive fashion. Preparing to deliver bad news by means of education and practice is recommended to help prevent or reduce psychological distress. One form of communication guidance is the ABCDE model, which involves Advance preparation, Building a therapeutic relationship or environment, Communicating well, Dealing with patient and family reactions, and Encouraging and validating emotions. An alternative model is the six-step SPIKES sequence-Setting, Perception, Invitation or Information, Knowledge, Empathy, and Strategize and Summarize. Using either model can assist in sensitive and empathetic communication. For both practitioners' and patients' well-being, empathetic and effective delivery of bad medical news should be included in dental school curricula and continuing education courses. Dental care providers should be familiar with the oral manifestations of diseases and the care needed before the patient undergoes medical treatment and use effective communication necessary to share bad news with patients.

The Veterans Health Administration (VA) has undertaken a major initiative to transform care through implementation of Patient Aligned Care Teams (PACTs). Based on the patient-centered medical home (PCMH) concept, PACT aims to improve access, continuity, coordination, and comprehensiveness using team-based care that is patient-driven and patient-centered. However, how VA should adapt PACT to meet the needs of special populations, such as women Veterans (WVs), was not considered in initial implementation guidance. WVs' numerical minority in VA healthcare settings (approximately 7-8 % of users) creates logistical challenges to delivering gender-sensitive comprehensive care. The main goal of this study is to test an evidence-based quality improvement approach (EBQI) to tailoring PACT to meet the needs of WVs, incorporating comprehensive primary care services and gender-specific care in gender-sensitive environments, thereby accelerating achievement of PACT tenets for women (Women's Health (WH)-PACT). EBQI is a systematic approach to developing a multilevel research-clinical partnership that engages senior organizational leaders and local quality improvement (QI) teams in adapting and implementing new care models in the context of prior evidence and local practice conditions, with researchers providing technical support, formative feedback, and practice facilitation. In a 12-site cluster randomized trial, we will evaluate WH-PACT model achievement using patient, provider, staff, and practice surveys, in addition to analyses of secondary administrative and chart-based data. We will explore impacts of receipt of WH-PACT care on quality of chronic disease care and prevention, health status, patient satisfaction and experience of care, provider experience, utilization, and costs. Using mixed methods, we will assess pre-post practice contexts; document EBQI activities undertaken in participating facilities and their relationship to provider/staff and team actions/attitudes; document WH-PACT implementation; and examine barriers/facilitators to EBQI-supported WH-PACT implementation through a combination of semi-structured interviews and monthly formative progress narratives and administrative data. Lack of gender-sensitive comprehensive care has demonstrated consequences for the technical quality and ratings of care among WVs and may contribute to decisions to continue use or seek care elsewhere under the US Affordable Care Act. We hypothesize that tailoring PACT implementation through EBQI may improve the experience and quality of care at many levels. ClinicalTrials.gov, NCT02039856.

For chronic conditions, disparities can take effect cumulatively at various times as the disease progresses, even when care is provided. The aim of this study was to quantify the prevalence of diabetes, congestive heart failure (CHF) and coronary heart disease (CHD) in adults by citizenship, and to compare the performance of primary care services in managing these chronic conditions, again by citizenship. This is a population-based retrospective cohort study on 1,948,622 people aged 16 years or more residing in Italy. A multilevel regression model was applied to analyze adherence to care processes using explanatory variables at both patient and district level. The age-adjusted prevalence of diabetes was found higher among immigrants from high migratory pressure countries (HMPC) than among Italians, while the age-adjusted prevalence of CHD and CHF was higher for Italians than for HMPC immigrants or those from highly-developed countries (HDC). Our results indicate lower levels in all quality management indicators for citizens from HMPC than for Italians, for all the chronic conditions considered. Patients from HDC did not differ from Italian in their adherence to disease management schemes. This study revealed a different prevalence of chronic diseases by citizenship, implying a different burden of primary care by citizenship. Our findings show that more effort is needed to guarantee migrant-sensitive primary health care.

Objective To examine the effects of varying diagnostic and pharmaceutical criteria on the performance of claims-based algorithms for identifying beneficiaries with hypertension, heart failure, chronic lung disease, arthritis, glaucoma, and diabetes. Study Setting Secondary 1999–2000 data from two Medicare+Choice health plans. Study Design Retrospective analysis of algorithm specificity and sensitivity. Data Collection Physician, facility, and pharmacy claims data were extracted from electronic records for a sample of 3,633 continuously enrolled beneficiaries who responded to an independent survey that included questions about chronic diseases. Principal Findings Compared to an algorithm that required a single medical claim in a one-year period that listed the diagnosis, either requiring that the diagnosis be listed on two separate claims or that the diagnosis to be listed on one claim for a face-to-face encounter with a health care provider significantly increased specificity for the conditions studied by 0.03 to 0.11. Specificity of algorithms was significantly improved by 0.03 to 0.17 when both a medical claim with a diagnosis and a pharmacy claim for a medication commonly used to treat the condition were required. Sensitivity improved significantly by 0.01 to 0.20 when the algorithm relied on a medical claim with a diagnosis or a pharmacy claim, and by 0.05 to 0.17 when two years rather than one year of claims data were analyzed. Algorithms that had specificity more than 0.95 were found for all six conditions. Sensitivity above 0.90 was not achieved all conditions. Conclusions Varying claims criteria improved the performance of case-finding algorithms for six chronic conditions. Highly specific, and sometimes sensitive, algorithms for identifying members of health plans with several chronic conditions can be developed using claims data. PMID:15533190

Lung disease in indigenous children.

Chang, A B; Brown, N; Toombs, M; Marsh, R L; Redding, G J

2014-12-01

Children in indigenous populations have substantially higher respiratory morbidity than non-indigenous children. Indigenous children have more frequent respiratory infections that are, more severe and, associated with long-term sequelae. Post-infectious sequelae such as chronic suppurative lung disease and bronchiectasis are especially prevalent among indigenous groups and have lifelong impact on lung function. Also, although estimates of asthma prevalence among indigenous children are similar to non-indigenous groups the morbidity of asthma is higher in indigenous children. To reduce the morbidity of respiratory illness, best-practice medicine is essential in addition to improving socio-economic factors, (eg household crowding), tobacco smoke exposure, and access to health care and illness prevention programs that likely contribute to these issues. Although each indigenous group may have unique health beliefs and interfaces with modern health care, a culturally sensitive and community-based comprehensive care system of preventive and long term care can improve outcomes for all these conditions. This article focuses on common respiratory conditions encountered by indigenous children living in affluent countries where data is available. Crown Copyright © 2014. Published by Elsevier Ltd.

To develop nursing-sensitive quality indicators consistent with current medical practices in Chinese neonatal intensive care units. The development of nursing-sensitive quality indicators has become a top priority in nursing management. To the best of our knowledge, there has been no objective, scientific and sensitive evaluation of the quality of neonatal intensive care unit nursing in China. A modified Delphi technique was used to seek opinions from experts about what should be used and prioritised as indicators of quality care in neonatal intensive care unit nursing. Based on a literature review, we identified 21 indicators of nursing-sensitive quality in the neonatal intensive care unit. Our group of 11 consultants chose 13 indicators to be discussed using the Delphi method. In October and November 2014, 39 neonatal intensive care unit experts in 18 tertiary hospitals spread across six provinces participated in two rounds of Delphi panels. Of the 13 indicators discussed, 11 were identified as indicators of nursing-sensitive quality in the neonatal intensive care unit: rate of nosocomial infections, rate of accidental endotracheal extubation, rate of errors in medication administration, rate of treatment for pain, rate of peripheral venous extravasation, rate of compliance with handwashing techniques, incidence of pressure ulcers, incidence of noise, the bed-to-care ratio, the proportion of nurses with greater than five years neonatal intensive care unit experience and incidence of retinopathy. The 11 neonatal intensive care unit nursing-sensitive indicators identified by the Delphi method integrated with basic Chinese practices provide a basis for nursing management and the monitoring of nursing quality. This study identified nursing-sensitive quality indicators for neonatal intensive care unit care that are suitable for current clinical practice in China. © 2016 John Wiley & Sons Ltd.

Recent Australian policy initiatives regarding primary health care focus on planning services around community needs and delivering these at the local area. As in many other countries, there has also been a growing concern over social inequities in health outcomes. The aims of the analysis presented here were firstly to describe small area variations in hospital admissions for ambulatory care sensitive conditions (ACSC) among children aged 0-4 years between 2003 and 2009 in the state of Victoria, Australia, and secondly to explore the relationship of ACSC hospitalisations with socio-economic disadvantage using a comparative analysis of the Child Social Exclusion (CSE) index and the Composite Score of Deprivation (CSD). This is a cross sectional secondary data analysis, with data sourced from 2003 to 2009 ACSC data from the Victorian State Government Department of Health; the Australian Standard Geographical Classification of remoteness; the Australian 2006 Census of Population and Housing; and AMPCo General Practitioner data from 2010. The relationship between the indexes and child health outcomes was examined through bivariate analysis and visually through a series of maps. The results show there is significant variation in the geographical distribution of the relationship between ACSCs and socio-economic disadvantage, with both indexes capturing important social gradients in child health conditions. However, measures of access, such as geographical accessibility and workforce supply, detect additional small area variation in child health outcomes. This research has important implications for future primary health care policy and planning of services, as these findings confirm that not all areas are the same in terms of health outcomes, and there may be benefit in tailoring mechanisms for identifying areas of need depending on the outcome intended to be affected.

To compare the probability of experiencing a potentially preventable hospitalization (PPH) between older dual eligible Medicaid home and community-based service (HCBS) users and nursing home residents. Three years of Medicaid and Medicare claims data (2003-2005) from seven states, linked to area characteristics from the Area Resource File. A primary diagnosis of an ambulatory care sensitive condition on the inpatient hospital claim was used to identify PPHs. We used inverse probability of treatment weighting to mitigate the potential selection of HCBS versus nursing home use. The most frequent conditions accounting for PPHs were the same among the HCBS users and nursing home residents and included congestive heart failure, pneumonia, chronic obstructive pulmonary disease, urinary tract infection, and dehydration. Compared to nursing home residents, elderly HCBS users had an increased probability of experiencing both a PPH and a non-PPH. HCBS users' increased probability for potentially and non-PPHs suggests a need for more proactive integration of medical and long-term care. © Health Research and Educational Trust.

In 2010 the Veterans Health Administration (VHA) began a nationwide initiative called Patient Aligned Care Teams (PACT) that reorganized care at all VHA primary care clinics in accordance with the patient-centered medical home model. We analyzed data for fiscal years 2003-12 to assess how trends in health care use and costs changed after the implementation of PACT. We found that PACT was associated with modest increases in primary care visits and with modest decreases in both hospitalizations for ambulatory care-sensitive conditions and outpatient visits with mental health specialists. We estimated that these changes avoided $596 million in costs, compared to the investment in PACT of $774 million, for a potential net loss of $178 million in the study period. Although PACT has not generated a positive return, it is still maturing, and trends in costs and use are favorable. Adopting patient-centered care does not appear to have been a major financial risk for the VHA. Project HOPE—The People-to-People Health Foundation, Inc.

Effect of the Economic Recession on Primary Care Access for the Homeless.

Primary care access (PCA) for the homeless can prove challenging, especially during periods of economic distress. In the United States, the most recent recession may have presented additional barriers to accessing care. Limited safety-net resources traditionally used by the homeless may have also been used by the non-homeless, resulting in delays in seeking treatment for the homeless. Using hospitalizations for ambulatory care sensitivity (ACS) conditions as a proxy measure for PCA, this study investigated the recession's impact on PCA for the homeless and non-homeless in four states. The State Inpatient Databases were used to identify ACS admissions. Findings from this study indicate the recession was a barrier to PCA for homeless people who were uninsured. Ensuring that economically-disadvantaged populations have the ability to obtain insurance coverage is crucial to facilitating PCA. With targeted outreach efforts, the Affordable Care Act provides an opportunity for expanding coverage to the homeless.

During the last decade, Chile's private health sector has experienced a dramatic increase in hospitalization rates, growing at four times the rate of ambulatory visits. Such evolution has raised concern among policy-makers. We studied the effect of ambulatory and hospital co-insurance rates on hospitalizations for ambulatory care sensitive conditions (ACSC) among individuals with private insurance in Chile. We used a large administrative dataset of private insurance claims for the period 2007-8 and a final sample of 2,792,662 individuals to estimate a structural model of two equations. The first equation was for ambulatory visits and the second for future hospitalizations for ACSC. We estimated the system by Two Stage Least Squares (2SLS) corrected by heteroskedasticity via Generalized Method of Moments (GMM) estimation. Results show that increased ambulatory visits reduced the probability of future hospitalizations, and increased ambulatory co-insurance decreased ambulatory visits for the adult population (19-65 years-old). Both findings indicate the need to reduce ambulatory co-insurance as a way to reduce hospitalizations for ACSC. Results also showed that increasing hospital co-insurance does have a statistically significant reduction on hospitalizations for the adult group, while it does not seem to have a significant effect on hospitalizations for the children (1-18 years-old) group. This paper's contribution is twofold: first, it shows how the level of co-insurance can be a determinant in avoiding unnecessary hospitalizations for certain conditions; second, it highlights the relevance for policy-making of using data on ACSC to improve the efficiency of health systems by promoting ambulatory care as well as population health.

The objective of this study was to (1) to describe the relationship between chinook conditions and illness related behaviour in women, aged 20 49 years, and (2) to examine the possibility of the existence of subgroups of chinook-sensitive women. At present no empirical evidence is available regarding a relationship between chinook conditions and illness related behaviours. This study comprises the secondary analysis of a large survery of various health and health-related factors of urban women aged 20 49 years, carried out in 1985 1986 in Calgary. The interview date was used to link behaviours to chinook conditions. We found no evidence of a significant relationship between the behaviours investigated and chinook conditions in the general population. However, the data strongly supported the concept of chinook sensitivity. Women with a history of chronic health problems were more likely to visit a health care professional on chinook days than healthy women and women in the subgroup aged less than 35 years cut down their usual daily activities during chinook conditions. Women with a history of recurring migraine headaches were less likely to take prescription medication on chinook days, and women with a history of emotional disorders were more likely to have higher scores on the accident scale and to report bursts of energy or excitement during chinook days. More research is needed to identify subgroups of susceptible persons, as well as to determine whether chinook sensitive persons are equally susceptible to weather changer of other types.

Poor developmental conditions can have long-lasting negative effects on offspring phenotypes, but impacts often differ among species. Contrasting responses may reflect disparities in experimental protocols among single-species studies or inherent differences among species in their sensitivity to early conditions and/or ability to mitigate negative impacts. We used a common experimental protocol to assess and compare the role of parental care in mitigating effects of poor early conditions on offspring among 4 sympatric bird species in the wild. We experimentally induced low incubation temperatures and examined effects on embryonic developmental rates, hatching success, nestling growth rates, and parental responses. We examined the generality of these effects across 4 species that differ in their phylogenetic history, breeding ecology, and life histories. We found that cooling led to delayed hatching in all species, but carry-over effects on offspring differed among species. Parents of some but not all species increased their offspring provisioning rates in response to experimental cooling with critical benefits for offspring growth rates. Our study shows for the first time that species exhibit clear differences in the degree to which they are affected by poor early conditions. Observed differences among species demonstrate that parental care is a critical mechanism for mitigating potential negative effects on offspring and suggest that parental responses may be constrained to varying degrees by ecology and life histories.

Research suggests that patient-perceived culturally sensitive health care encompasses multiple components of the health care delivery system including the cultural sensitivity of front desk office staff. Despite this, research on culturally sensitive health care focuses almost exclusively on provider behaviors, attitudes, and knowledge. This is due in part to the paucity of instruments available to assess the cultural sensitivity of front desk office staff. Thus, the objective of the present study is to determine the psychometric properties of the pilot Tucker-Culturally Sensitive Health Care Office Staff Inventory-Patient Form (T-CSHCOSI-PF), which is an instrument designed to enable patients to evaluate the patient-defined cultural sensitivity of their front desk office staff. A sample of 1648 adult patients was recruited by staff at 67 health care sites across the United States. These patients anonymously completed the T-CSHCOSI-PF, a demographic data questionnaire, and a patient satisfaction questionnaire. Findings Confirmatory factor analyses of the TCSHCOSI-PF revealed that this inventory has two factors with high internal consistency reliability and validity (Cronbach's αs=0.97 and 0.95). It is concluded that the T-CSHCOSI-PF is a psychometrically strong and useful inventory for assessing the cultural sensitivity of front desk office staff. This inventory can be used to support culturally sensitive health care research, evaluate the job performance of front desk office staff, and aid in the development of trainings designed to improve the cultural sensitivity of these office staff.

Longitudinal data are used to examine whether effects of early child care are amplified and/or attenuated by later parenting. Analyses tested these interactions using parenting as both a categorical and continuous variable to balance power and flexibility in testing moderation. The most consistent finding was that maternal sensitivity during adolescence accentuated the association between child care quality and adolescent academic-cognitive skills at age 15 years when maternal sensitivity during adolescence was high. This interaction was obtained in analyses with maternal sensitivity as both a categorical and continuous variable. Relations between early child care hours and adolescent behavioral outcomes also were moderated by maternal sensitivity, with longer child care hours predicting more impulsivity and externalizing at age 15 when maternal sensitivity during middle childhood, scored as a categorical variable, was low to moderate and when maternal sensitivity during adolescence, scored as a continuous variable, was lower. These findings suggest that some child care effects are moderated by subsequent parenting and that this moderation may take both linear and nonlinear forms. PMID:23937381

Objective To assess the sensitivity to change of the McMaster Toronto Arthritis Patient Preference Disability Questionnaire (MACTAR) in chronic low back pain (CLBP) and shifts in patients' priorities of disabling activities over time. Methods A prospective longitudinal survey of 100 patients (38 males) with CLBP in a tertiary care teaching hospital. Evaluation at baseline and 6 months by the MACTAR, Quebec Back Pain Disability Questionnaire (QUEBEC), Hospital Anxiety and Depression scale (HAD), Fear-Avoidance Beliefs Questionnaire (FABQ), Coping Strategies Questionnaire (CSQ), and pain and handicap visual analogue scales (VASs). Patients' perceived improvement or worsening of condition was assessed at 6 months. Effect size (ES) and Standardized response mean (SRM) and effect size (ES) were used to evaluate sensitivity to change of the MACTAR. Results The MACTAR SRM and ES values (SRM = 0.25; ES = 0.37) were among the highest for the instruments evaluated. For patients considering their condition as improved, the SRM was 0.66 and the ES 1. The 3 disability domains, classified by the International Classification of Functioning, Disability and Health (ICF), most often cited as priorities at baseline remained the most cited at follow-up: mobility (40.9% of patients); community, social and civic life (22.7%); and domestic life (22.4%). At 6 months, 48 patients shifted their priorities, for a decrease in MACTAR SRM and ES values for patients considering their condition improved and an increase in these values for those considering their condition deteriorated. Conclusions Although the MACTAR has similar sensitivity to change as other outcome measures widely used in CLBP, shifts in patient priorities over time are common and influence scores and sensitivity to change.

The objective of this study is to investigate whether the characteristics of the structure of primary health units and the work process of primary care teams are associated with the number of hospitalizations for primary care sensitive conditions. In this ecological study, we have analyzed data of Brazilian municipalities related to sociodemographic characteristics, coverage of care programs, structure of primary health units, and work process of primary care teams. We have obtained the data from the first cycle of the Brazilian Program for Improving Access and Quality of the Primary Care, of the Department of Information Technology of the Brazilian Unified Health System, the Brazilian Institute of Geography and Statistics, and the United Nations Development Programme. The associations have been estimated using negative binomial regression coefficients (β) and respective 95% confidence intervals, with a hierarchical approach in three levels (alpha = 5%). In the adjusted analysis for the outcome in 2013, in the distal level, the coverage of the Bolsa Família Program (β = -0.001) and private insurance (β = -0.01) had a negative association, and the human development index (β = 1.13), the proportion of older adults (β = 0.05) and children under the age of five (β = 0.05), and the coverage of the Community Health Agent Strategy (β = 0.002) showed positive association with hospitalizations for primary care sensitive conditions. In the intermediate level, minimum hours (β = -0.14) and availability of vaccines (β = -0.16) showed a negative association, and availability of medications showed a positive association (β = 0.16). In the proximal level, only the variable of matrix support (β = 0.10) showed a positive association. The variables in the adjusted analysis of the number of hospitalizations for primary care sensitive conditions in 2014 presented the same association as in 2013. The characteristics of the structure of primary health units and the work process of the primary care teams impact the number of hospitalizations for primary care sensitive conditions in Brazilian municipalities. Investigar se características da estrutura das unidades básicas de saúde e do processo de trabalho das equipes de atenção básica estão associadas ao número de internações por condições sensíveis à atenção primária. Neste estudo ecológico, foram analisados dados de municípios brasileiros relativos a características sociodemográficas, de cobertura de programas assistenciais, de estrutura das unidades básicas de saúde e processo de trabalho das equipes de atenção básica. Os dados foram obtidos do primeiro ciclo do Programa de Melhoria do Acesso e Qualidade da Atenção Básica, do Departamento de Informática do Sistema Único de Saúde, do Instituto Brasileiro de Geografia e Estatística e do Programa das Nações Unidas. Estimaram-se as associações por meio de coeficientes de regressão binomial negativa (β) e respectivos intervalos de confiança a 95%, com abordagem hierarquizada em três blocos (alpha = 5%). Na análise ajustada, para o desfecho em 2013, no bloco distal, a cobertura do Programa Bolsa Família (β = -0,001) e de plano privado (β = -0,01) apresentaram associação negativa; e o índice de desenvolvimento humano (β = 1,13), a proporção de pessoa idosa (β = 0,05) e de menor de cinco anos (β = 0,05) e a cobertura da Estratégia de Agentes Comunitários de Saúde (β = 0,002) mostraram associação positiva com internações por condições sensíveis à atenção primária. No bloco intermediário, apresentaram associação negativa o horário mínimo (β = -0,14) e a disponibilidade de vacina (β = -0,16); e associação positiva, a disponibilidade de medicamentos (β = 0,16). No bloco proximal, apenas a variável apoio matricial (β = 0,10) mostrou associação positiva. Na análise ajustada do número de internações por condições sensíveis à atenção primária em 2014, as variáveis apresentaram o mesmo sentido de associação de 2013. Características da estrutura das unidades básicas de saúde e do processo de trabalho das equipes de atenção básica impactam no número de internações por condições sensíveis à atenção primária nos municípios brasileiros.

In seeking to provide universal health care through its primary care-oriented Family Health Program, Brazil has attempted to reduce hospitalization rates for preventable illnesses such as childhood gastroenteritis. We measured rates of Primary Care-sensitive Hospitalizations and evaluated the impact of the Family Health Program on pediatric gastroenteritis trends in high-poverty Northeast Brazil. We analyzed aggregated municipal-level data in time-series between years 1999-2007 from the Brazilian health system payer database and performed qualitative, in-depth key informant interviews with public health experts in municipalities in Bahia. Data were sampled for Bahia’s Salvador microregion, a population of approximately 14 million. Gastroenteritis hospitalization rates among children aged less than five years were evaluated. Declining hospitalization rates were associated with increasing coverage by the PSF (P=0.02). After multivariate adjustment for garbage collection, sanitation, and water supply, evidence of this association was no longer significant (P=0.28). Qualitative analysis confirmed these findings with a framework of health determinants, proximal causes, and health system effects. The PSF, with other public health efforts, was associated with decreasing gastroenteritis hospitalizations in children. Incentives for providers and more patient-centered health delivery may contribute to strengthening the PSF’s role in improving primary health care outcomes in Brazil. PMID:23932060

We sought to determine if a novel, publicly available measure of neighborhood context, the Child Opportunity Index, was associated with pediatric acute care visit frequency and diagnoses. This cross-sectional study included San Francisco residents <18 years of age with an emergency department and/or urgent care visit to any of 3 medical systems ( N = 47 175) between 2007 and 2011. Hot-spot analysis was used to compare the spatial distribution of neighborhood child opportunity and income. Generalized estimating equation logistic regression models were used to examine independent associations between neighborhood child opportunity and frequent acute care use (≥4 visits per year) and diagnosis group after adjusting for neighborhood income and patient age, sex, race and/or ethnicity, payer, and health system. Neighborhood child opportunity and income had distinct spatial distributions, and we identified different clusters of high- and low-risk neighborhoods. Children living in the lowest opportunity neighborhoods had significantly greater odds of ≥4 acute care visits per year (odds ratio 1.33; 95% confidence interval 1.03-1.73) compared with those in the highest opportunity neighborhoods. Neighborhood child opportunity was negatively associated with visits for respiratory conditions, asthma, assault, and ambulatory care-sensitive conditions but positively associated with injury-related visits. The Child Opportunity Index could be an effective tool for identifying neighborhood factors beyond income related to child health. Copyright © 2018 by the American Academy of Pediatrics.

Policy makers require estimates of comparative effectiveness that apply to the population of interest, but there has been little research on quantitative approaches to assess and extend the generalizability of randomized controlled trial (RCT)-based evaluations. We illustrate an approach using observational data. Our example is the Whole Systems Demonstrator (WSD) trial, in which 3230 adults with chronic conditions were assigned to receive telehealth or usual care. First, we used novel placebo tests to assess whether outcomes were similar between the RCT control group and a matched subset of nonparticipants who received usual care. We matched on 65 baseline variables obtained from the electronic medical record. Second, we conducted sensitivity analysis to consider whether the estimates of treatment effectiveness were robust to alternative assumptions about whether "usual care" is defined by the RCT control group or nonparticipants. Thus, we provided alternative estimates of comparative effectiveness by contrasting the outcomes of the RCT telehealth group and matched nonparticipants. For some endpoints, such as the number of outpatient attendances, the placebo tests passed, and the effectiveness estimates were robust to the choice of comparison group. However, for other endpoints, such as emergency admissions, the placebo tests failed and the estimates of treatment effect differed markedly according to whether telehealth patients were compared with RCT controls or matched nonparticipants. The proposed placebo tests indicate those cases when estimates from RCTs do not generalize to routine clinical practice and motivate complementary estimates of comparative effectiveness that use observational data. Future RCTs are recommended to incorporate these placebo tests and the accompanying sensitivity analyses to enhance their relevance to policy making. © The Author(s) 2015.

The AHRQ's Prevention Quality Indicators assume inpatient hospitalizations for certain conditions, referred as ambulatory-care sensitive (ACS) conditions, are potentially preventable and may indicate reduced access to and a lower quality of ambulatory care. Using a cohort drawn from the Medicare Current Beneficiary Survey (MCBS) linked to Medicare claims, we examined the extent to which barriers to healthcare are associated with ACS hospitalizations and related costs, and whether these associations differ by beneficiaries' disability status. Our results indicate that the regression-adjusted cost of ACS hospitalizations for elderly Medicare beneficiaries with no disabilities was $799. This cost increased six-fold, by $5148, among beneficiaries with mild disability, by $9045 for beneficiaries with moderate disability, by $5513 for those with severe disability, and by $8557 for persons with complete disability (P < 0.001). Persons reporting having foregone or delayed needed medical care because of financial difficulties (+$2082, P = .05), those experiencing low satisfaction with care coordination (+$1714, P = .01), and those reporting low satisfaction with access to care (+$1237, P = .02) also incurred significant excess ACS hospitalization costs relative to persons reporting no such barriers. This pattern held true for those with and without a disability, but were especially marked among persons with no functional limitations. These findings suggest that a better understanding of how public policy might effectively improve care coordination and reduce financial barriers to care is essential to formulating programs that reduce excess hospitalizations among the large and growing number of elderly Medicare beneficiaries.

To evaluate a new alcohol-related risk score for research use. Using data from a previously reported trial of a screening and education system for older adults (Computerized Alcohol-Related Problems Survey), secondary analyses were conducted comparing the ability of two different measures of risk to detect post-intervention group differences: the original categorical outcome measure and a new, finely grained quantitative risk score based on the same research-based risk factors. Three primary care group practices in southern California. Six hundred sixty-five patients aged 65 and older. A previously calculated, three-level categorical classification of alcohol-related risk and a newly developed quantitative risk score. Mean post-intervention risk scores differed between the three experimental conditions: usual care, patient report, and combined report (P<.001). The difference between the combined report and usual care was significant (P<.001) and directly proportional to baseline risk. The three-level risk classification did not reveal approximately 57.3% of the intervention effect detected by the risk score. The risk score also was sufficiently sensitive to detect the intervention effect within the subset of hypertensive patients (n=112; P=.001). As an outcome measure in intervention trials, the finely grained risk score is more sensitive than the trinary risk classification. The additional clinical value of the risk score relative to the categorical measure needs to be determined.

Healthcare systems in many low income countries have evolved to provide services for acute, infections and are poorly structured for the provision of chronic, non-communicable diseases which are increasingly common. Epilepsy is a common chronic neurologic condition and antiepileptic drugs are affordable, but the epilepsy treatment gap remains >90% in most African countries. The World Health Organization has recently released evidence-based guidelines for epilepsy care provision at the primary care level. Based upon these guidelines, we estimated all direct costs associated with epilepsy care provision as well as the cost of healthcare worker training and social marketing. We developed a model for epilepsy care delivery primarily by primary healthcare workers. We then used a variety of sources to develop cost estimates for the actual implementation and maintenance of this program being as comprehensive as possible to include all costs incurred within the health sector. Key sensitivity analyses were completed to better understand how changes in costs for individual aspects of care impact the overall cost of care delivery. Even after including the costs of healthcare worker retraining, social marketing and capital expenditures, epilepsy care can be provided at less than $25.00 per person with epilepsy per year. This is substantially less than for drugs alone for other common chronic conditions. Implementation of epilepsy care guidelines for patients receiving care at the primary care level is a cost effective approach to decreasing the epilepsy treatment gap in high gap, low income countries.

The study analyzed health professionals' conceptions toward female users of crack and powder cocaine currently receiving psychosocial care, based on a gender perspective. Seventeen health professionals were interviewed, and systematic observations were made of the spaces for collective care in a Center for Psychosocial Care specializing in alcohol and drug addiction in Greater Metropolitan Rio de Janeiro, Brazil. Analysis of the interviews and field diaries using the hermeneutic-dialectic method revealed three categories: frailty as a constitutive attribute of women's condition, the women's emotional addiction to crack and powder cocaine use, and gender stereotypes during psychosocial care. The health professionals voiced a traditional view of the heterosexual, docile, and maternal woman and reproduced stereotypical concepts when addressing female crack and cocaine users as sensitive, frail individuals, emotionally dependent on men and more involved in the home and family. These professionals need a more refined understanding of gender issues in the mental health-disease process in order to allow overcoming preconceived notions and reductionist health care practices.

Purpose. The aim of this study was to assess whether the home care score (HCS), which was developed by the Ministry of Health and Welfare in Japan in 1992, is useful for the prediction of advisability of home care. Methods. Subjects living at home and in assisted-living facilities were analyzed. Binominal logistic regression analyses, using age, sex, the functional independence measure score, and the HCS, along with receiver operating characteristic curve analyses, were conducted. Findings/Conclusions. Only HCS was selected for the regression equation. Receiver operating characteristic curve analysis revealed that the area under the curve (0.9), sensitivity (0.82), specificity (0.83), and positive predictive value (0.84) for HCS were higher than those for the functional independence measure, indicating that the HCS is a powerful predictor for advisability of home care. Clinical Relevance. Comprehensive measurements of the condition of provided care and the activities of daily living of the subjects, which are included in the HCS, are required for the prediction of advisability of home care.

Standard economic theory postulates that decisions are driven by stable context-insensitive preferences, while motivation psychology suggests they are driven by distinct context-sensitive motives with distinct evolutionary goals and characteristic psycho-physiological and behavioral patterns. To link these fields and test how distinct motives could differentially predict different types of economic decisions, we experimentally induced participants with either a Care or a Power motive, before having them take part in a suite of classic game theoretical paradigms involving monetary exchange. We show that the Care induction alone raised scores on a latent factor of cooperation-related behaviors, relative to a control condition, while, relative to Care, Power raised scores on a punishment-related factor. These findings argue against context-insensitive stable preferences and theories of strong reciprocity and in favor of a motive-based approach to economic decision making: Care and Power motivation have a dissociable fingerprint in shaping either cooperative or punishment behaviors.

Background Primary care is accessible and ideally placed for case finding of patients with lifestyle and mental health risk factors and subsequent intervention. The short self-administered Case-finding and Help Assessment Tool (CHAT) was developed for lifestyle and mental health assessment of adult patients in primary health care. This tool checks for tobacco use, alcohol and other drug misuse, problem gambling, depression, anxiety and stress, abuse, anger problems, inactivity, and eating disorders. It is well accepted by patients, GPs and nurses. Aim To assess criterion-based validity of CHAT against a composite gold standard. Design of study Conducted according to the Standards for Reporting of Diagnostic Accuracy statement for diagnostic tests. Setting Primary care practices in Auckland, New Zealand. Method One thousand consecutive adult patients completed CHAT and a composite gold standard. Sensitivities, specificities, positive and negative predictive values, and likelihood ratios were calculated. Results Response rates for each item ranged from 79.6 to 99.8%. CHAT was sensitive and specific for almost all issues screened, except exercise and eating disorders. Sensitivity ranged from 96% (95% confidence interval [CI] = 87 to 99%) for major depression to 26% (95% CI = 22 to 30%) for exercise. Specificity ranged from 97% (95% CI = 96 to 98%) for problem gambling and problem drug use to 40% (95% CI = 36 to 45%) for exercise. All had high likelihood ratios (3–30), except exercise and eating disorders. Conclusion CHAT is a valid and acceptable case-finding tool for most common lifestyle and mental health conditions.

to characterize the profile and describe the moral sensitivity of primary health care nurses. this is a quantitative, transversal, exploratory, descriptive study. The data were collected through the Moral Sensitivity Questionnaire translated and adapted to Brazil. 100 primary health care nurses participated, from Rio Grande do Sul, Brazil. The data collection took place during the months of March and July 2016, in an online form. The analysis of the data occurred through descriptive statistical analysis. the nurses had an average moral sensitivity of 4.5 (out of 7). The dimensions with the greatest moral sensitivity were: interpersonal orientation, professional knowledge, moral conflict and moral meaning. the nurses of Rio Grande do Sul have a moderate moral sensitivity, which may contribute to a lower quality in Primary Health Care.

Nonmaternal Care’s Association With Mother’s Parenting Sensitivity: A Case of Self-Selection Bias?

Nomaguchi, Kei M.; DeMaris, Alfred

2013-01-01

Although attachment theory posits that the use of nonmaternal care undermines quality of mothers’ parenting, empirical evidence for this link is inconclusive. Using data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 1,233), the authors examined the associations between nonmaternal care characteristics and maternal sensitivity during the first 3 years of children’s lives, with special attention to selection effects and moderation by resource levels. Findings from fixed-effects regression models suggested that, on average, there is little relationship between nonmaternal care characteristics and maternal sensitivity, once selection factors are held constant. Some evidence of moderation effects was found, however. Excellent-quality care is related to more sensitivity for mothers with lower family income. Poor-quality care is related to lower sensitivity for single mothers, but not partnered mothers. In sum, nonmaternal care characteristics do not seem to have as much influence on mothers’ parenting as attachment theory claims. PMID:23772093

Moral sensitivity is the foremost prerequisite to ethical performance; a review of literature shows that nurses are sometimes not sensitive enough for a variety of reasons. Moral distress is a frequent phenomenon in nursing, which may result in paradoxes in care, dealing with patients and rendering high-quality care. This may, in turn, hinder the meeting of care objectives, thus affecting social healthcare standards. The present research was conducted to determine the relationship between moral sensitivity and moral distress of nurses in intensive care units. This study is a descriptive-correlation research. Lutzen's moral sensitivity questionnaire and Corley Moral Distress Questionnaire were used to gather data. Participants and research context: A total of 153 qualified nurses working in the hospitals affiliated to Shahid Beheshti University of Medical Sciences were selected for this study. Subjects were selected by census method. Ethical considerations: After explaining the objectives of the study, all the participants completed and signed the written consent form. To conduct the study, permission was obtained from the selected hospitals. Nurses' average moral sensitivity grade was 68.6 ± 7.8, which shows a moderate level of moral sensitivity. On the other hand, nurses also experienced a moderate level of moral distress (44.8 ± 16.6). Moreover, there was no meaningful statistical relationship between moral sensitivity and moral distress (p = 0.26). Although the nurses' moral sensitivity and moral distress were expected to be high in the intensive care units, it was moderate. This finding is consistent with the results of some studies and contradicts with others. As moral sensitivity is a crucial factor in care, it is suggested that necessary training be provided to develop moral sensitivity in nurses in education and practical environments. Furthermore, removing factors that contribute to moral distress may help decrease it in nurses.

Sewer deterioration modeling with condition data lacking historical records.

Accurate predictions of future conditions of sewer systems are needed for efficient rehabilitation planning. For this purpose, a range of sewer deterioration models has been proposed which can be improved by calibration with observed sewer condition data. However, if datasets lack historical records, calibration requires a combination of deterioration and sewer rehabilitation models, as the current state of the sewer network reflects the combined effect of both processes. Otherwise, physical sewer lifespans are overestimated as pipes in poor condition that were rehabilitated are no longer represented in the dataset. We therefore propose the combination of a sewer deterioration model with a simple rehabilitation model which can be calibrated with datasets lacking historical information. We use Bayesian inference for parameter estimation due to the limited information content of the data and limited identifiability of the model parameters. A sensitivity analysis gives an insight into the model's robustness against the uncertainty of the prior. The analysis reveals that the model results are principally sensitive to the means of the priors of specific model parameters, which should therefore be elicited with care. The importance sampling technique applied for the sensitivity analysis permitted efficient implementation for regional sensitivity analysis with reasonable computational outlay. Application of the combined model with both simulated and real data shows that it effectively compensates for the bias induced by a lack of historical data. Thus, the novel approach makes it possible to calibrate sewer pipe deterioration models even when historical condition records are lacking. Since at least some prior knowledge of the model parameters is available, the strength of Bayesian inference is particularly evident in the case of small datasets. Copyright © 2013 Elsevier Ltd.

Prevalence of Contact Allergens in Personal Care Products for Babies and Children.

PubMed

Bonchak, Jonathan G; Prouty, Megan E; de la Feld, Salma F

Personal care products marketed for babies and children are often regarded as "safe" or "gentle." However, little is known about the prevalence of contact allergens in these types of products. This study assessed the prevalence of important sensitizers in personal care products marketed for babies and children. A secondary objective of this study was to determine whether a product's cost correlates with content of sensitizing ingredients. The ingredient lists of 533 unique personal care products were analyzed for presence of fragrance, betaines, propylene glycol, methylchloroisothiazolinone, methylisothiazolinone, formaldehyde, lanolin, and neomycin. Price per ounce was determined for each product as well. Most personal care products for babies and children contain 1 or more sensitizers. Products containing more sensitizers tend to cost less than those without any sensitizing ingredients.

Controlling Chaos Via Knowledge of Initial Condition for a Curved Structure

NASA Technical Reports Server (NTRS)

Maestrello, L.

2000-01-01

Nonlinear response of a flexible curved panel exhibiting bifurcation to fully developed chaos is demonstrated along with the sensitivity to small perturbation from the initial conditions. The response is determined from the measured time series at two fixed points. The panel is forced by an external nonharmonic multifrequency and monofrequency sound field. Using a low power time-continuous feedback control, carefully tuned at each initial condition, produces large long-term effects on the dynamics toward taming chaos. Without the knowledge of the initial conditions, control may be achieved by destructive interference. In this case, the control power is proportional to the loading power. Calculation of the correlation dimension and the estimation of positive Lyapunov exponents, in practice, are the proof of chaotic response.

Medically unexplained physical symptoms (MUPS) among adults in Canada: Comorbidity, health care use and employment.

Park, Jungwee; Gilmour, Heather

2017-03-15

Based on data from the 2014 Canadian Community Health Survey and the 2012 Canadian Community Health Survey-Mental Health, this study provides estimates of the prevalence of medically unexplained physical symptoms (MUPS) in the household population aged 25 or older. MUPS are examined in relation to sociodemographic characteristics, physical and mental comorbidity, health care use and unmet needs, labour force participation and productivity. In 2014, 5.5% of Canadian adults-an estimated 1.3 million - reported having chronic fatigue syndrome (1.6%), fibromyalgia (2.0%) and/or multiple chemical sensitivity (2.7%). Half (51%) of people with MUPS reported other chronic physical conditions, compared with 8% of those without MUPS. Similarly, mental comorbidities were more prevalent among those with MUPS. Higher health care use was observed among people with MUPS, but 25% of them reported unmet health care needs, compared with 11% of those without MUPS. People with MUPS were more likely than those without MUPS to be permanently unable to work or to not have a job; fewer than half (45%) were employed. Among those who were employed, 18% had missed work because of a chronic condition, compared with 5% of workers without MUPS.

People living with dementia (PLWD) have a high prevalence of comorbidty. The aim of this study was to explore the impact of dementia on access to non-dementia services and identify ways of improving service delivery for this population. Qualitative study involving interviews and focus groups. Thematic content analysis was informed by theories of continuity of care and access to care. Primary and secondary care in the South and North East of England. PLWD who had 1 of the following comorbidities-diabetes, stroke, vision impairment, their family carers and healthcare professionals (HCPs) in the 3 conditions. We recruited 28 community-dwelling PLWD, 33 family carers and 56 HCPs. Analysis resulted in 3 overarching themes: (1) family carers facilitate access to care and continuity of care, (2) the impact of the severity and presentation of dementia on management of comorbid conditions, (3) communication and collaboration across specialities and services is not dementia aware. We found examples of good practice, but these tended to be about the behaviour of individual practitioners rather than system-based approaches; current systems may unintentionally block access to care for PLWD. This study suggests that, in order to improve access and continuity for PLWD and comorbidity, a significant change in the organisation of care is required which involves: coproduction of care where professionals, PLWD and family carers work in partnership; recognition of the way a patient's diagnosis of dementia affects the management of other long-term conditions; flexibility in services to ensure they are sensitive to the changing needs of PLWD and their family carers over time; and improved collaboration across specialities and organisations. Research is needed to develop interventions that support partnership working and tailoring of care for PLWD and comorbidity. Published by the BMJ Publishing Group Limited.

Bedside ultrasonography for diagnosis of pneumothorax

PubMed Central

Chen, Lin

2015-01-01

Ultrasonography (US) has found its way into the critical care and emergency settings for the evaluation of acute respiratory failure conditions in recent years. It is useful for the diagnosis of varieties of abnormalities involving pleura and lung such as pleural effusion, alveolar interstitial syndrome, and pneumothorax (PTX). In addition to its reproducibility and timeliness, US has high sensitivity and specificity for the diagnosis of these conditions. The most widely used method for bedside evaluation of PTX is chest X-ray (CXR). However, the diagnostic sensitivity of CXR in detecting PTX is limited especially in occult PTX and when the patient is assumed supine position. Computed tomography (CT) is the gold standard in the evaluation of PTX, but is limited by its high radiation exposure and safety concerns in transporting critically ill patients. In this paper we review current advances in PTX diagnosis using US. PMID:26435925

Effects of video-feedback intervention on harmonious parent-child interaction and sensitive discipline of parents with intellectual disabilities: A randomized controlled trial.

PubMed

Hodes, M W; Meppelder, M; de Moor, M; Kef, S; Schuengel, C

2018-03-01

This study tested whether video-feedback intervention based on attachment and coercion theory increased harmonious parent-child interaction and sensitive discipline of parents with mild intellectual disabilities or borderline intellectual functioning. Observer ratings of video-recorded structured interaction tasks at home formed pretest, post-test, and 3-month follow-up outcome data in a randomized controlled trial with 85 families. Repeated measures analyses of variance and covariance were conducted to test for the intervention effect and possible moderation by IQ and adaptive functioning. The intervention effect on harmonious parent-child interaction was conditional on parental social adaptive behaviour at pretest, with lower adaptive functioning associated with stronger intervention benefit at post-test and follow-up compared to care as usual. Intervention effects were not conditional on parental IQ. Intervention effects for sensitive discipline were not found. Although the video-feedback intervention did not affect observed parenting for the average parent, it may benefit interaction between children and parents with lower parental adaptive functioning. © 2017 John Wiley & Sons Ltd.

Fibromyalgia and overlapping disorders: the unifying concept of central sensitivity syndromes.

PubMed

Yunus, Muhammad B

2007-06-01

To discuss fibromyalgia syndrome (FMS) and overlapping conditions, eg, irritable bowel syndrome, headaches, and chronic fatigue syndrome, within the concept of central sensitivity syndromes (CSS). A critical overview of the literature and incorporation of the author's own views. The concept of CSS seems viable. It is based on mutual associations among the CSS conditions as well as the evidence for central sensitization (CS) among several CSS members. However, such evidence is weak or not available in other members at this time, requiring further studies. The biology of CSS is based on neuroendocrine aberrations, including CS, that interact with psychosocial factors to cause a number of symptoms. CSS is an important new concept that embraces the biopsychosocial model of disease. Further critical studies are warranted to fully test this concept. However, it seems to have important significance for new directions for research and patient care involving physician and patient education. Each patient, irrespective of diagnosis, should be treated as an individual considering both the biological and psychosocial contributions to his or her symptoms and suffering.

The sensitivity of localized surface plasmon resonance (LSPR) of metal nanostructures to adsorbates lends itself to a powerful class of label-free biosensors. Optical properties of plasmonic nanostructures are dependent on the geometrical features and the local dielectric environment. The exponential decay of the sensitivity from the surface of the plasmonic nanotransducer calls for the careful consideration in its design with particular attention to the size of the recognition and analyte layers. In this study, we demonstrate that short peptides as biorecognition elements (BRE) compared to larger antibodies as target capture agents offer several advantages. Using a bioplasmonic paper device (BPD), we demonstrate the selective and sensitive detection of the cardiac biomarker troponin I (cTnI). The smaller sized peptide provides higher sensitivity and a lower detection limit using a BPD. Furthermore, the excellent shelf-life and thermal stability of peptide-based LSPR sensors, which precludes the need for special storage conditions, makes it ideal for use in resource-limited settings.

The case of value-based healthcare for people living with complex long-term conditions.

There is a trend towards value-based health service, striving to cut costs while generating value for the patient. The overall objective comprises higher-quality health services and improved patient safety and cost efficiency. The approach could align with patient-centred care, as it entails a focus on the patient's experience of her or his entire cycle of care, including the use of well-defined outcome measurements. Challenges arise when the approach is applied to health services for people living with long-term complex conditions that require support from various healthcare services. The aim of this work is to critically discuss the value-based approach and its implications for patients with long-term complex conditions. Two cases from clinical practice and research form the foundation for our reasoning, illustrating several challenges regarding value-based health services for people living with long-term complex conditions. Achieving value-based health services that provide the health outcomes that matter to patients and providing greater patient-centredness will place increased demands on the healthcare system. Patients and their informal caregivers must be included in the development and establishment of outcome measures. The outcome measures must be standardized to allow evaluation of specific conditions at an aggregated level, but they must also be sensitive enough to capture each patient's individual needs and goals. Healthcare systems that strive to establish value-based services must collaborate beyond the organizational boundaries to create clear patient trajectories in order to avoid fragmentation. The shift towards value-based health services has the potential to align healthcare-service delivery with patient-centred care if serious efforts to take the patient's perspective into account are made. This is especially challenging in fragmented healthcare systems and for patients with long-term- and multi-setting-care needs.

The Refuah Shlema programme was established to reduce health disparities, promote health literacy and health indicators of the Ethiopian immigrant community in Israel, and included: (i) integrating Ethiopian immigrant liaisons in primary care as inter-cultural mediators; (ii) in-service training of clinical staff to increase cultural awareness and sensitivity; and (iii) health education community activities. Qualitative and quantitative evidence showed improvements in: (i) clinic staff–patient relations; (ii) availability and accessibility of health services, and health system navigation without increasing service expenditure; (iii) perception of general well-being; and (iv) self-care practice with regards to chronic conditions. Evidence significantly contributed to sustaining the programme for over 13 years.

Despite the high rate of smoking cessation treatment non-response, relatively little empirical work has examined predictors of treatment non-response. The present study sought to explore the effect of smoking outcome expectancies on treatment response in a sample of treatment-seeking adult daily smokers (N=182; 53.3% female; M age =40.67; SD=13.63). Results indicated that expectancies for smoking to reduce negative affect were related to an increased likelihood of treatment non-response (OR=0.73, CI: 0.54, 0.98). These findings remained significant after controlling for sex, presence of Axis I disorder, tobacco-related health problems, tobacco dependence, anxiety sensitivity, and condition assignment as well as other smoking expectancy dimensions. Post hoc analyses revealed that this relation was stronger for smokers in the integrated care condition vs. the standard care condition (Interaction: OR=1.69, CI: 1.05, 2.73). Additionally, expectancies for smoking to enhance positive affect and provide sensory satisfaction were associated with an increased likelihood of treatment response in the standard care condition. The current findings suggest expectancies that smoking will alleviate negative affect may be a risk factor of smoking cessation treatment non-response. Additionally, findings provide evidence that the relation between smoking expectancies and treatment non-response may differ by smoking cessation treatment. Copyright © 2017 Elsevier Ltd.

Colloidal gold is the first choice for labeling antibodies to be used in Point Of Care Testing. However, there are some recent reports on a family of textile dyes-named "reactive dyes"-being suitable for protein labeling. In the present article, protein labeling conditions were optimized for Remazol Brilliant Violet 5R, and the sensitivity of the labeled antibodies was assessed and compared with that of colloidal-gold labeled antibodies. Also, the accelerated stability was explored. Optimal conditions were pH 10.95, dye:Ab molar ratio of 264 and an incubation time of 132 min. Labeled antibodies were stable, and could be successfully used in a slot blot assay, detecting as low as 400 ng/mL. Therefore, the present work demonstrates that vinylsulphonic reactive dyes can be successfully used to label antibodies, and are excellent candidates for the construction of a new generation of Point of Care Testing kits.

Health information exchange and healthcare utilization.

PubMed

Vest, Joshua R

2009-06-01

Health information exchange (HIE) makes previously inaccessible data available to clinicians, resulting in more complete information. This study tested the hypotheses that HIE information access reduced emergency room visits and inpatient hospitalizations for ambulatory care sensitive conditions among medically indigent adults. HIE access was quantified by how frequently system users' accessed patients' data. Encounter counts were modeled using zero inflated binomial regression. HIE was not accessed for 43% of individuals. Patient factors associated with accessed data included: prior utilization, chronic conditions, and age. Higher levels of information access were significantly associated with increased counts of all encounter types. Results indicate system users were more likely to access HIE for patients for whom the information might be considered most beneficial. Ultimately, these results imply that HIE information access did not transform care in the ways many would expect. Expectations in utilization reductions, however logical, may have to be reevaluated or postponed.

To evaluate a dignity care intervention provided by community nurses seeking to address dignity concerns for people with advanced and life-limiting conditions. Evidence would suggest that dying people fear a loss of dignity and a central focus of palliative care is to assist people to die with dignity. Whilst community nurses have a key role to play in the delivery of palliative care, specific interventions for dignity are lacking. A mixed methods study using online survey and focus group interviews and thematic analysis to examine data. Twenty four community nurses implemented the dignity care intervention for people with advanced and life-limiting conditions were recruited from four pilot sites across Ireland. Four focus group interviews and on line survey were conducted between March-June 2015. The community nurses found the dignity care intervention useful. It helped the nurses to provide holistic end-of-life care and assisted in the overall assessment of palliative care patients, identifying areas that might not otherwise have been noted. Whilst it was a useful tool for communication, they noted that it stimulated some emotionally sensitive conversations for which they felt unprepared. Implementing the dignity care intervention in practice was challenging. However, the dignity care intervention facilitated holistic assessment and identified patient dignity-related concerns that may not have been otherwise identified. Further support is required to overcome barriers and enable dignity-conserving care. Ensuring dignity is a key aspect of palliative and end-of-life care; however, community nurses may not feel equipped to address this aspect of care. Implementing a dignity care intervention can assist in identifying patient dignity-related concerns and provision of holistic care. Community nurses need more training to assist in difficult conversations relating to dignity and end-of-life care. © 2017 John Wiley & Sons Ltd.

Assessing decision quality in patient-centred care requires a preference-sensitive measure

2014-01-01

A theory-based instrument for measuring the quality of decisions made using any form of decision technology, including both decision-aided and unaided clinical consultations is required to enable person- and patient-centred care and to respond positively to individual heterogeneity in the value aspects of decision making. Current instruments using the term ‘decision quality’ have adopted a decision- and thus condition-specific approach. We argue that patient-centred care requires decision quality to be regarded as both preference-sensitive across multiple relevant criteria and generic across all conditions and decisions. MyDecisionQuality is grounded in prescriptive multi criteria decision analysis and employs a simple expected value algorithm to calculate a score for the quality of a decision that combines, in the clinical case, the patient’s individual preferences for eight quality criteria (expressed as importance weights) and their ratings of the decision just taken on each of these criteria (expressed as performance rates). It thus provides an index of decision quality that encompasses both these aspects. It also provides patients with help in prioritizing quality criteria for future decision making by calculating, for each criterion, the Incremental Value of Perfect Rating, that is, the increase in their decision quality score that would result if their performance rating on the criterion had been 100%, weightings unchanged. MyDecisionQuality, which is a web-based generic and preference-sensitive instrument, can constitute a key patient-reported measure of the quality of the decision-making process. It can provide the basis for future decision improvement, especially when the clinician (or other stakeholders) completes the equivalent instrument and the extent and nature of concordance and discordance can be established. Apart from its role in decision preparation and evaluation, it can also provide real time and relevant documentation for the patient’s record. PMID:24335587

Comparative analysis of health system performance in Montreal and New York: the importance of context for interpreting indicators.

Although eliminating financial barriers to care is a necessary condition for improving access to health services, it is not sufficient. Given the contrasting health systems with regard to financing and organization of health insurance in the United States and Canada, there is a long history of comparing these countries. We extend the empirical studies on the Canadian and US health systems by comparing access to ambulatory care as measured by hospitalization rates for ambulatory care sensitive conditions (ACSC) in Montreal and New York City. We find that, in New York, ACSC rates were more than twice as high (12.6 per 1000 population) as in Montreal (4.8 per 1000 population). After controlling for age, sex, and number of diagnoses, significant differences in ACSC rates are present in both cities, but are more pronounced in New York. Our findings are consistent with the hypothesis that universal, first-dollar health insurance coverage has contributed to lower ACSC rates in Montreal than New York. However, Montreal's surprisingly low ACSC rate calls for further research.

Sensitivity relations in optimal control provide an interpretation of the costate trajectory and the Hamiltonian, evaluated along an optimal trajectory, in terms of gradients of the value function. While sensitivity relations are a straightforward consequence of standard transversality conditions for state constraint free optimal control problems formulated in terms of control-dependent differential equations with smooth data, their verification for problems with either pathwise state constraints, nonsmooth data, or for problems where the dynamic constraint takes the form of a differential inclusion, requires careful analysis. In this paper we establish validity of both ‘full’ and ‘partial’ sensitivity relations for an adjointmore » state of the maximum principle, for optimal control problems with pathwise state constraints, where the underlying control system is described by a differential inclusion. The partial sensitivity relation interprets the costate in terms of partial Clarke subgradients of the value function with respect to the state variable, while the full sensitivity relation interprets the couple, comprising the costate and Hamiltonian, as the Clarke subgradient of the value function with respect to both time and state variables. These relations are distinct because, for nonsmooth data, the partial Clarke subdifferential does not coincide with the projection of the (full) Clarke subdifferential on the relevant coordinate space. We show for the first time (even for problems without state constraints) that a costate trajectory can be chosen to satisfy the partial and full sensitivity relations simultaneously. The partial sensitivity relation in this paper is new for state constraint problems, while the full sensitivity relation improves on earlier results in the literature (for optimal control problems formulated in terms of Lipschitz continuous multifunctions), because a less restrictive inward pointing hypothesis is invoked in the proof, and because it is validated for a stronger set of necessary conditions.« less

Educational and therapeutic behavioral approaches to providing dental care for patients with Autism Spectrum Disorder.

2015-01-01

Autism Spectrum Disorder (ASD) is a condition which most dentists will encounter in their practices. Contemporary educational and behavioral approaches may facilitate successful dental care. A literature review was conducted for relevant information on dental care for children with ASD. Educational principles used for children with ASD can be applied in the dental setting. Examples include: parent involvement in identifying strengths, sensitivities, and goal setting; using stories or video modeling in advance of the appointment; dividing dental treatment into sequential components; and modification of the environment to minimize sensory triggers. Patients with ASD are more capable of tolerating procedures that they are familiar with, and therefore should be exposed to new environments and stimuli in small incremental steps. By taking time to understand children with ASD as individuals and employing principles of learning, clinicians can provide high quality dental care for the majority of patients with ASD. © 2014 Special Care Dentistry Association and Wiley Periodicals, Inc.

Integrated management of childhood illness (IMNCI) is already operational in many states of India, but there are only limited studies in Indian scenario comparing its validity and reliability with the decisions of pediatricians. Aims and. To assess the validity and reliability of the IMNCI algorithm with provisional diagnosis of senior pediatricians for each IMNCI classifications. The present study is done with all the young infants between 0-2 months presented during the study period with a fresh episode of illness to test the validity and reliability of the algorithm in comparison to provisional diagnoses of senior pediatricians. The study was done in a tertiary care hospital. Validity characteristics such as sensitivity, specificity, positive predictive value, negative predictive value, and reliability characteristics such as percent agreement and Kappa were assessed for individual IMNCI classifications. The sensitivity of possible serious bacterial infection, local bacterial infection, jaundice, no dehydration and possible serious bacterial infection, not able to feed were 88.89, 14.29, 66.67, 25 and 44.44% respectively. The specificities for the same conditions were 71.72, 99.09, 99.07, 94.50 and 86.87%. Percent agreements for similar conditions were 74, 94, 97, 90 and 80% respectively and the Kappa ratios were 0.38, 0.20, 0.73, 0.19 and 0.29 respectively. It could be concluded that IMNCI is quite a sensitive strategy and could identify severe illnesses of young infants requiring referral to higher facility. Further studies, particularly in primary health care setting, are required.

Masculinity and urogenital cancer: sensitive issues in health care.

Nobis, Regina; Sand, Inger; Elofsson, Kristina

2007-02-01

The aim of this literature review was to analyse the approaches adopted by patients, health professionals, spouses and other care-givers towards sensitive issues related to male urogenital cancer, and to describe how these findings can be applied in health care practice. The findings revealed five identifiable domains, namely 'the barrier to talking', 'the barrier of sensitivity', 'the barrier of masculinity', 'the barrier to seeking health care' and 'the communicative barrier'. The conclusion was that the phenomenon of a barrier is strongly connected with hegemonic masculinity. The review of literature confirmed that, for many men, talking about genitally-related health problems is not easy and that health care professionals need to learn more about gender and masculinity in order to address urogenitally sensitive issues.

Women Veterans are a significant minority of users of the VA healthcare system, limiting provider and staff experience meeting their needs in environments historically designed for men. The VA is nonetheless committed to ensuring that women Veterans have access to comprehensive care in environments sensitive to their needs. We sought to determine what aspects of care need to be tailored to the needs of women Veterans in order for the VA to deliver gender-sensitive comprehensive care. Modified Delphi expert panel process. Eleven clinicians and social scientists with expertise in women's health, primary care, and mental health. Importance of tailoring over 100 discrete aspects of care derived from the Institute of Medicine's definition of comprehensive care and literature-based domains of sex-sensitive care on a 5-point scale. Panelists rated over half of the aspects of care as very-to-extremely important (median score 4+) to tailor to the needs of women Veterans. The panel arrived at 14 priority recommendations that broadly encompassed the importance of (1) the design/delivery of services sensitive to trauma histories, (2) adapting to women's preferences and information needs, and (3) sex awareness and cultural transformation in every facet of VA operations. We used expert panel methods to arrive at consensus on top priority recommendations for improving delivery of sex-sensitive comprehensive care in VA settings. Accomplishment of their breadth will require national, regional, and local strategic action and multilevel stakeholder engagement, and will support VA's national efforts at improving customer service for all Veterans.

CONTEXT Community health centers (CHCs) provide essential access to a primary care medical home for the uninsured, especially in rural communities with no other primary care safety net. CHCs could potentially reduce uninsured emergency department (ED) visits in rural communities. PURPOSE We compared uninsured ED visit rates between rural counties in Georgia which have a community health center clinic site vs. counties without a CHC presence. METHODS We analyzed data from 100% of ED visits occurring in 117 rural (non-metropolitan statistical area [MSA]) counties in Georgia from 2003-2005. Counties were classified as having a CHC presence if a federally funded (Section 330) community health center had a primary care delivery site in that county throughout the study period. The main outcome measure was uninsured ED visit rates among the uninsured (all-cause ED visits and visits for ambulatory care sensitive conditions). Poisson regression models were used to examine the relationship between ED rates and presence of a CHC. To assure that the effects were unique to the uninsured population, we ran similar analyses on insured ED visits. FINDINGS Counties without a community health center primary care clinic site had 33% higher rates of uninsured all-cause ED visits per 10,000 uninsured population compared with non-CHC counties (rate ratio=1.33, 95% CI=1.11-1.59). Higher ED visit rates remained significant (RR=1.21, 95% CI=1.02-1.42) after adjustment for percent of population below poverty level, percent black, and number of hospitals. Uninsured ED visit rates were also higher for various categories of diagnoses, but remained statistically significant on multivariate analysis only for ambulatory care sensitive conditions (adjusted RR=1.22, 95% CI=1.01-1.47). No such relationship was found for ED visit rates of insured patients (RR=1.06, 95% CI=0.92-1.22). CONCLUSIONS Absence of a community health center is associated with a substantial excess in uninsured ED visits in rural counties, an excess not seen for ED visit rates among the insured.

Acute infection is the most common presentation of children in primary care with only few having a serious infection (eg, sepsis, meningitis, pneumonia). To avoid complications or death, early recognition and adequate referral are essential. Clinical prediction rules have the potential to improve diagnostic decision-making for rare but serious conditions. In this study, we aimed to validate a recently developed decision tree in a new but similar population. Diagnostic accuracy study validating a clinical prediction rule. Acutely ill children presenting to ambulatory care in Flanders, Belgium, consisting of general practice and paediatric assessment in outpatient clinics or the emergency department. Physicians were asked to score the decision tree in every child. The outcome of interest was hospital admission for at least 24 h with a serious infection within 5 days after initial presentation. We report the diagnostic accuracy of the decision tree in sensitivity, specificity, likelihood ratios and predictive values. In total, 8962 acute illness episodes were included, of which 283 lead to admission to hospital with a serious infection. Sensitivity of the decision tree was 100% (95% CI 71.5% to 100%) at a specificity of 83.6% (95% CI 82.3% to 84.9%) in the general practitioner setting with 17% of children testing positive. In the paediatric outpatient and emergency department setting, sensitivities were below 92%, with specificities below 44.8%. In an independent validation cohort, this clinical prediction rule has shown to be extremely sensitive to identify children at risk of hospital admission for a serious infection in general practice, making it suitable for ruling out.

Diagnostic accuracy: sensitivity and specificity of the ScreenAssist Lumbar Questionnaire in comparison with primary care provider tests and measures of low back pain: a pilot study

PubMed Central

Cunningham, Shala

2013-01-01

Objective: The purpose of this study was to estimate the diagnostic accuracy of the ScreenAssist Lumbar Questionnaire (SALQ) to determine the presence of non-musculoskeletal pain or emergent musculoskeletal pain, in terms of its sensitivity and specificity, when compared with the assessment and diagnosis made by primary care providers. Methods: Subjects were patients presenting to a primary care physician’s office with the main complaint of low back pain. SALQ data were collected within 24 hours of the appointment. A 2-month post-visit chart review was performed in order to compare scores and recommendations made by the questionnaire with the assessment and diagnosis made by the physician. Results: The SALQ demonstrated a sensitivity of 100% (95% CI = 0.445–1.0) and specificity of 92% (95% CI = 0.831–0.920). The negative likelihood ratio was 0.11 (95% CI = 0.01–1.54) and the positive likelihood ratio was 9.36 (95% CI = 2.78–32). If the SALQ was positive, the post-test probability was 0.60. If the SALQ was negative, the post-test probability was 0.017. Discussion: Results from this study suggest that the SALQ can be used as an adjunct to the subjective history taking in a physical therapy evaluation to assist in the recognition of non-musculoskeletal or emergent musculoskeletal conditions requiring referral.

Atopic disorders are a global concern. Studies in migrant populations can illuminate the interplay of genetic and environmental factors. Exposures related to bad housing (indoor dampness, mould growth, crowding etc.) are likely to play a role in how socioeconomic inequalities can turn into health disparities for disadvantaged populations. The sizable immigrant population living in very poor-quality housing in Malmö, Sweden, became the focus of a cross-sectional study. To describe atopic disorders and sensitizations in a population living in substandard housing in Malmö, Sweden, with an emphasis on their relation to harmful exposures from the built environment. Families were recruited via identification of any children with symptomatic airway afflictions from health care records, and also asymptomatic children from school lists. Interviewer-led health questionnaire data and data from self-reports about living conditions were obtained together with data from home inspections carried out by health communicators. Families underwent skin prick tests (SPT) against common aeroallergens. As could be expected from background demographic information, it turned out that we effectively studied an immigrant population inhabiting very precarious housing outside the center of Malmö. A total of 359 children from 130 families (total 650 participants) were included. Overall the prevalence of potentially harmful environmental exposures was high (signs of moisture or mould in more than 50% of apartments, indoor smoking in 37% of households). Atopic disorders were common among both adults and children. SPTs showed a spectrum of sensitizations consistent with unselected populations in Sweden. Paternal sensitization in the SPT was associated with higher risk of sensitization for offspring than maternal sensitization. Few statistically significant associations of atopic sensitization with studied environmental exposures were detected (for example objective signs of dampness /mould in bathrooms). There were marked discrepancies between asthma diagnoses obtained from the health records and parental reports of such diagnoses and treatment for their children. The atopic burden in this selected immigrant population was high, and results point to unmet medical needs. Health care systems caring for such populations need to be aware of their specific health needs; comprehensive asthma and allergy care should include consideration of harmful environmental exposures, adhering to the precautionary principle.

Intercultural communication between patients and health care providers: an exploration of intercultural communication effectiveness, cultural sensitivity, stress, and anxiety.

Cultural diversity is becoming increasingly more important in the workplace. This is particularly true in health care organizations facing demographic shifts in the patients served and their families. This study serves to aid the development of intercultural communication training programs for health care providers by examining how cultural sensitivity and effective intercultural communication, besides helping patients, personally benefit health care providers by reducing their stress. Effective intercultural communication and cultural sensitivity were found to be related. Health care providers' levels of intercultural anxiety also were found to correlate with effective intercultural communication.

2011-04-01

At the research reactor Forschungs-Neutronenquelle Heinz Maier-Leibnitz (FRM II) a new Prompt Gamma-ray Activation Analysis (PGAA) facility was installed. The instrument was originally built and operating at the spallation source at the Paul Scherrer Institute in Switzerland. After a careful re-design in 2004-2006, the new PGAA instrument was ready for operation at FRM II. In this paper the main characteristics and the current operation conditions of the facility are described. The neutron flux at the sample position can reach up 6.07×1010 [cm-2 s-1], thus the optimisation of some parameters, e.g. the beam background, was necessary in order to achieve a satisfactory analytical sensitivity for routine measurements. Once the optimal conditions were reached, detection limits and sensitivities for some elements, like for example H, B, C, Si, or Pb, were calculated and compared with other PGAA facilities. A standard reference material was also measured in order to show the reliability of the analysis under different conditions at this instrument.

Cancer patients' respect experiences in relation to perceived communication behaviours from hospital staff: analysis of the 2012-2013 National Cancer Patient Experience Survey.

Respect experiences are poorly understood despite respect being central to professionalism in health care and patient well-being, and needed for optimal patient care. This study explores which patient-perceived communication behaviours from hospital staff contribute most to cancer patients' respect experiences and account for variation in their experience by socio-demographic and clinical characteristics. We present a secondary analysis of data from the 2012-2013 National Cancer Patient Experience Survey of 45,191 patients with a primary cancer diagnosis treated in English National Health Service trusts providing adult acute cancer services who provided data on experienced respect and dignity. Both autonomy-supportive and caring/emotionally sensitive behaviours were associated with reported respect, although the latter showed stronger associations and accounted for most differences in reports of respect between patient groups. Differences in respect were found by gender, race/ethnicity, age, the presence of long-standing conditions, treatment response, time since first treated for cancer (p < .001), employment and type of cancer (p < .05). The study questions the tendency to conceptualise respect primarily in terms of autonomy-supportive behaviours and shows the relative contribution of autonomy-supportive and caring/emotionally sensitive behaviours in explaining disparities in respect experiences. More attention should be paid to affective communication behaviours from hospital staff to reduce disparities in respect experiences.

Clinical innovation for promoting family care in paediatric intensive care: demonstration, role modelling and reflective practice.

To explore family caregiving problems in paediatric crisis care and methods that could be applied to move the abstraction of family care to development of specific family interventions. Family centred care has been accepted as the ideal philosophy for holistic health care of children, but methods for its implementation are not well established. In paediatric health crises, family care requires special sensitivity to family needs and a type of complex nursing care for which many practitioners are not sufficiently prepared. Developing family sensitive models of intervention and finding a strategy for transfer of this knowledge to clinical practice is an important challenge facing family nursing today. Social learning theory provides a rich background to explore these issues. Specific techniques of role modelling and reflective practice are suggested as effective approaches to teach family sensitive care in clinical settings where families are part of the care environment.

Plastics can induce three main groups of respiratory accidents.--Acute and subacute intoxications related to the inhalation of volatil substances from decomposing plastics (mostly during burning and pyrolysis) or on the contrary during synthesis. They are accidental chemical broncho-pneumopathies (acute tracheo-bronchitis and pulmonary edema).--Chronic broncho-pneumopathies following repeated inhalation of dusts or suspension of plastics: pneumoconioses and thesaurismoses leading to pulmonary fibrosis.--Broncho-pneumopathies related to the irritant and sensitizing action of some components of plastics: professional asthma and sensitization pneumopathies. Diagnosis of such diseases therefore imposes a careful study of working conditions. Proof rests on two arguments:--curing by risk eviction;--analysis of the products in order to reveal their toxicity.

Cortisol Patterns for Young Children Displaying Disruptive Behavior: Links to a Teacher-Child, Relationship-Focused Intervention.

PubMed

Hatfield, Bridget E; Williford, Amanda P

2017-01-01

Supportive and close relationships that young children have with teachers have lasting effects on children's behavior and academic success, and this is particularly true for children with challenging behaviors. These relationships are also important for children's developing stress response system, and children in child care may be more likely to display atypical cortisol patterns at child care. However, warm, supportive relationships with teachers may buffer these negative effects of child care. While many relationship-focused early childhood interventions demonstrate changes in child behavior, associations with children's stress response system are unknown. This study assessed children's activity in the hypothalamic-pituitary-adrenal axis via salivary cortisol as a function of their participation in a dyadic intervention intended to improve a teacher's interaction quality with a particular child. Seventy teachers and 113 preschool children participated who were part of a larger study of teachers and children were randomly assigned at the classroom level across three intervention conditions: Banking Time, Time-Control Comparison (Child Time), and Business-as-Usual. At the end of the school year, children in the Banking Time condition displayed a significantly greater decline in cortisol across the morning during preschool compared to children in Business-as-Usual condition. These pilot results are among the first to provide preliminary evidence that school-based interventions that promote sensitive and responsive interactions may improve young children's activity in the stress response system within the child care/early education context.

Designing robots for care: care centered value-sensitive design.

PubMed

van Wynsberghe, Aimee

2013-06-01

The prospective robots in healthcare intended to be included within the conclave of the nurse-patient relationship--what I refer to as care robots--require rigorous ethical reflection to ensure their design and introduction do not impede the promotion of values and the dignity of patients at such a vulnerable and sensitive time in their lives. The ethical evaluation of care robots requires insight into the values at stake in the healthcare tradition. What's more, given the stage of their development and lack of standards provided by the International Organization for Standardization to guide their development, ethics ought to be included into the design process of such robots. The manner in which this may be accomplished, as presented here, uses the blueprint of the Value-sensitive design approach as a means for creating a framework tailored to care contexts. Using care values as the foundational values to be integrated into a technology and using the elements in care, from the care ethics perspective, as the normative criteria, the resulting approach may be referred to as care centered value-sensitive design. The framework proposed here allows for the ethical evaluation of care robots both retrospectively and prospectively. By evaluating care robots in this way, we may ultimately ask what kind of care we, as a society, want to provide in the future.

Better Quality of Care or Healthier Patients? Hospital Utilization by Medicare Advantage and Fee-for-Service Enrollees

PubMed Central

Nicholas, Lauren Hersch

2013-01-01

Do differences in rates of use among managed care and Fee-for-Service Medicare beneficiaries reflect selection bias or successful care management by insurers? I demonstrate a new method to estimate the treatment effect of insurance status on health care utilization. Using clinical information and risk-adjustment techniques on data on acute admission that are unrelated to recent medical care, I create a proxy measure of unobserved health status. I find that positive selection accounts for between one-quarter and one-third of the risk-adjusted differences in rates of hospitalization for ambulatory care sensitive conditions and elective procedures among Medicare managed care and Fee-for-Service enrollees in 7 years of Healthcare Cost and Utilization Project State Inpatient Databases from Arizona, Florida, New Jersey and New York matched to Medicare enrollment data. Beyond selection effects, I find that managed care plans reduce rates of potentially preventable hospitalizations by 12.5 per 1,000 enrollees (compared to mean of 46 per 1,000) and reduce annual rates of elective admissions by 4 per 1,000 enrollees (mean 18.6 per 1,000).

To determine whether the Patient-Centered Medical Home (PCMH) transformation reduces hospital and ED utilization, and whether the effect is specific to chronic conditions targeted for management by the PCMH in our setting. All patients aged 18 years and older in 2,218 primary care practices participating in a statewide PCMH incentive program sponsored by Blue Cross Blue Shield of Michigan (BCBSM) in 2009-2012. Quantitative observational study, jointly modeling PCMH-targeted versus other hospital admissions and ED visits on PCMH score, patient, and practice characteristics in a hierarchical multivariate model using the generalized gamma distribution. Claims data and PCMH scores held by BCBSM. Both hospital and ED utilization were reduced proportionately to PCMH score. Hospital utilization was reduced by 13.9 percent for PCMH-targeted conditions versus only 3.8 percent for other conditions (p = .003), and ED utilization by 11.2 percent versus 3.7 percent (p = .010). Hospital PMPM cost was reduced by 17.2 percent for PCMH-targeted conditions versus only 3.1 percent for other conditions (p < .001), and ED PMPM cost by 9.4 percent versus 3.6 percent (p < .001). PCMH transformation reduces hospital and ED use, and the majority of the effect is specific to PCMH-targeted conditions. © Health Research and Educational Trust.

Decision validity should determine whether a generic or condition-specific HRQOL measure is used in health care decisions.

PubMed

Dowie, Jack

2002-01-01

When a HRQOL measure is needed in health care decision making should it be a generic measure (a GEN), intended to cover the entire domain of health, a condition-specific measure (a CSM) intended to embrace those aspects of health associated with the condition concerned, or both? This paper proposes that it will never be appropriate to use both a CSM and a GEN for the same decision; that a GEN alone will probably be the appropriate measure in the majority of decisions; that a CSM alone will sometimes be appropriate; and that whether it is a GEN alone or a CSM alone that is appropriate depends entirely on the structure of the decision. The argument rests on the distinction between knowledge validity and decision validity. But it has a supplementary basis in rejection of the widespread (but unjustifiable) belief that CSMs are more "sensitive" or "responsive" than GENs and hence can detect "small but important changes" that GENs always or often miss.

2012-12-01

Medical technologies, although often crucial for the provision of healthcare, may carry unintended significance for patients and their families. The highly technicised neonatal intensive care unit (NICU) is the place where parents of hospitalised baby have their early encounters with their child. The aim of this study is to investigate phenomenologically how the contact and relation between parent and child may be affected by the mediating presence and use of the techno-medical features and equipments of the NICU. Three common technologies are examined for the ways they condition the kinds of contact afforded between parents and child: the isolette, the feeding tube and the brain imaging equipment. The concluding recommendations speak of the need for understanding the relational experiences of parents of hospitalised babies, and the tactful sensitivities required of the healthcare teams who provide care to these families.

Respiratory syncytial virus (RSV) is responsible for severe respiratory infections and higher costs in medical care. The two aims of this work were to assess the performances of SOFIA ® RSV tests in "real-life-laboratory" conditions (study 1) and implemented at point-of-care testing in a pediatric emergency department (ED, study 2), during two consecutive winter seasons. In study 1, fresh nasopharyngeal swabs from patients of all ages were sampled in 1.5 ml of Universal virological Transport Medium (UTM) and prospectively tested using SOFIA ® RSV tests. In study 2, conducted in a pediatric ED, nasopharyngeal swabs were placed in 3 ml of UTM. All SOFIA ® RSV tests were confirmed by molecular testing, considered as reference method. The epidemiological and clinical features of tested patients, as well as the care of these patients after obtaining quick results were evaluated. The sensitivities of SOFIA ® RSV in infants (aged under 24 months) performed in the laboratory and in the pediatric ED were respectively 95% (95% CI: 86.8-98.1) and 74.8% (95% CI: 68.0-80.9) compared to PCR. In study 1, the sensitivity among children (from 2 to 15 years old) and adults (above 15 years old) dropped to 45% (95% CI: 23.1-68.5) and 59% (95% CI: 32.9-81.6), respectively. In study 2, there were some differences in bed-management of SOFIA ® RSV positive compared to SOFIA ® RSV negative infants. SOFIA ® RSV tests performed in the laboratory and in the pediatric ED show high and satisfactory sensitivities among young children under 24 months, which supports its robustness and reliability. However, the impact of these tests on patient care at point-of-care cannot be clearly assessed when considering the limits of the study 2 design.

Behavioral and endocrine consequences of placentophagia in male California mice (Peromyscus californicus).

Ingestion of placenta by mammalian mothers can lead to changes in pain sensitivity, hormone levels, and behavioral responses to newborns. In some biparental mammals, males, in addition to females, ingest placenta when their offspring are born. In the monogamous, biparental California mouse (Peromyscus californicus), males first become attracted to placenta when cohabitating with their pregnant mate, and virgin males administered placenta are less neophobic than males given oil vehicle. In this study, we investigated the effects of placentophagia on pain sensitivity, anxiety-like behavior, behavioral responses to pups, and circulating corticosterone levels of both breeding and nonbreeding male California mice. We orally administered either a conspecific placenta or oil vehicle to male mice from three reproductive conditions (first-time fathers, first-time expectant fathers, and virgin males) and tested their pain sensitivity 1 h later, as well as their exploratory behavior and paternal responsiveness in an open field 4 h post-treatment. We measured plasma corticosterone immediately after the open-field test. We found that placenta-treated males, independent of reproductive condition, traveled significantly longer distances in the open field than males treated with oil, indicative of lower anxiety. Additionally, fathers had shorter latencies to approach and to care for pups (i.e., huddling and licking pups), and spent more time engaging in these behaviors, than did age-matched expectant fathers and virgin males, independent of treatment. We found no effect on plasma corticosterone levels or pain sensitivity as a result of either treatment or reproductive condition. These findings indicate that placenta ingestion decreases anxiety-related behaviors in male California mice, but might not influence pain sensitivity, paternal responsiveness, or plasma corticosterone concentrations.

Exploring Provider Reactions to Decision Aid Distribution and Shared Decision Making: Lessons from Two Specialties.

2017-01-01

A critical component of shared decision making (SDM) is the role played by health care providers in distributing decision aids (DAs) and initiating SDM conversations. Existing literature indicates that decisions about designing and implementing DAs must take provider perspectives into account. However, little is known about how differences in provider attitudes across specialties may impact DA implementation and how provider attitudes may shift after DA implementation. Group Health's Decision Aid Implementation project was carried out in six specialties using 12 video-based DAs for preference-sensitive conditions; this study focused on two of the six specialties. In-depth, qualitative interviews with specialty care providers in two specialties-orthopedics and cardiology-at two time points during DA implementation. Data were analyzed using a thematic analysis approach. We interviewed 19 care providers in orthopedics and cardiology. All respondents believed that providing patients with accurate information on their health conditions and treatment options was important and that most patients wanted an active role in decision making. However, respondents diverged in decision-making styles and views on the practicality and appropriateness of using the DAs and SDM. For example, cardiology specialists were ambivalent about DAs for coronary artery disease because many viewed DAs and SDM as unnecessary or inappropriate for this clinical condition. Provider attitudes towards DAs and SDM were generally stable over two years. Limitations include a lack of patient perspectives, social desirability bias, and possible selection bias. Successfully implementing DAs in clinical practice to promote SDM requires addressing individual provider attitudes, beliefs, and knowledge of SDM by specialty. During DA development and implementation, providers should be asked for input about the specific conditions and care processes that are most appropriate for SDM. © The Author(s) 2016.

The social environment influences health outcomes for older adults and could be an important target for interventions to reduce costly medical care. We sought to understand which elements of the social environment distinguish communities that achieve lower health care utilization and costs from communities that experience higher health care utilization and costs for older adults with complex needs. We used a sequential explanatory mixed methods approach. We classified community performance based on three outcomes: rate of hospitalizations for ambulatory care sensitive conditions, all-cause risk-standardized hospital readmission rates, and Medicare spending per beneficiary. We conducted in-depth interviews with key informants (N = 245) from organizations providing health or social services. Higher performing communities were distinguished by several aspects of social environment, and these features were lacking in lower performing communities: 1) strong informal support networks; 2) partnerships between faith-based organizations and health care and social service organizations; and 3) grassroots organizing and advocacy efforts. Higher performing communities share similar social environmental features that complement the work of health care and social service organizations. Many of the supportive features and programs identified in the higher performing communities were developed locally and with limited governmental funding, providing opportunities for improvement.

Acne is a common skin disease that involves the seborrheic area of the face and results from the obstruction of hair follicles followed by inflammation. Careful face washing helps to improve and prevent acne; however, intensive washing has a risk of inducing skin barrier impairment and dry skin, especially in sensitive skin. We hypothesized that skin care combining mild skin cleansing and intensive moisturizing ("combination skin care") may be effective in the care of acne in subjects with dry skin and/or sensitive skin. We developed a combination skin care with a weakly acidic foaming facial skin cleanser based on a mild detergent, an aqueous lotion with eucalyptus extract and a moisturizing gel containing pseudo-ceramide and eucalyptus extract. To optimize an ideal facial skin care system for mild acne on sensitive skin, we performed a 4-week clinical trial with 29 post-adolescent Japanese women with mild acne with dry and sensitive skin. The acne significantly decreased after this trial accompanied by the improvement of dry skin, a significantly increased endogenous ceramide level in the stratum corneum and an elongated alkyl chain length of the non-hydroxy acyl sphingosine type ceramide. No adverse events due to the test samples were observed. Based on diagnosis by a dermatologist, 97% of the subjects found the combination skin care to be "useful" or "slightly useful". Based on these findings, the combined use of a facial skin cleanser and moisturizers is safe and effective for the care of acne in post-adolescent Japanese women with sensitive skin. © 2014 Japanese Dermatological Association.

Children vary hugely in how demanding of their caregivers they are. This creates differences in demands on parents during observation, making the comparison of sensitivity between parents difficult. It would therefore be of interest to create standard situations in which all caregivers are faced with the same level of demand. This study developed an ecologically valid but standardized setting using an infant simulator with interactive features, the Leiden Infant Simulator Sensitivity Assessment (LISSA). The infant simulator resembles a real infant in appearance and it produces crying sounds that are life-like. The simulator begins with fussing and progresses to more intense crying in case of no care or inappropriate care. It responds by being calm again if appropriate care is given. One hundred and eighty-one female participants took care of the infant simulator for two evenings and in a 30 min lab session with increasing competing demands. Sensitive parenting behavior during the lab session was coded with the Ainsworth Sensitivity Scale. Sensitivity ratings covered the whole range of the scale (1-9), and were stable across settings (free play, competing demands). Sensitivity was related to an increase of positive affect during caretaking, and insensitivity was related to intended harsh caregiving response during a computerized cry paradigm. Sensitivity was unrelated to social desirability and self-reported quality of care given to the infant simulator. We discuss the potentials of the infant simulator for research on sensitive parenting, for preventive interventions, and for clinical practices.

Correction of static pressure on a research aircraft in accelerated flight using differential pressure measurements

2012-11-01

A method is described that estimates the error in the static pressure measurement on an aircraft from differential pressure measurements on the hemispherical surface of a Rosemount model 858AJ air velocity probe mounted on a boom ahead of the aircraft. The theoretical predictions for how the pressure should vary over the surface of the hemisphere, involving an unknown sensitivity parameter, leads to a set of equations that can be solved for the unknowns - angle of attack, angle of sideslip, dynamic pressure and the error in static pressure - if the sensitivity factor can be determined. The sensitivity factor was determined on the University of Wyoming King Air research aircraft by comparisons with the error measured with a carefully designed sonde towed on connecting tubing behind the aircraft - a trailing cone - and the result was shown to have a precision of about ±10 Pa over a wide range of conditions, including various altitudes, power settings, and gear and flap extensions. Under accelerated flight conditions, geometric altitude data from a combined Global Navigation Satellite System (GNSS) and inertial measurement unit (IMU) system are used to estimate acceleration effects on the error, and the algorithm is shown to predict corrections to a precision of better than ±20 Pa under those conditions. Some limiting factors affecting the precision of static pressure measurement on a research aircraft are discussed.

Assessing the vulnerability of society to ocean acidification (OA) demands an understanding of both the sensitivity of economically important species together with an organism's exposure to potentially harmful carbonate chemistry conditions. However, research has revealed that sensitivity to OA is frequently life-stage dependent and the environmental conditions experienced by a marine organism often vary with life-stage. Enhancing the development of a National Ocean Acidification Observing Network (NOA-ON) and establishing appropriate treatment conditions for experimental studies requires careful consideration of where the vulnerable life-stages of an organism reside in space (e.g., estuary versus oceanic), depth (e.g., surface mixed layer versus benthos), and time (e.g., diel vertical migration, seasonality of the chemical environment within the context of an organism life cycle). Few studies have explicitly attempted to document carbonate chemistry dynamics specific to a given organism's life-cycle. Here we estimate carbonate dynamics in terms of aragonite saturation state range and variability within the U.S. Northeast and West Coast through the application of NOAA's NOA-ON assets mapped out with respect to the life stages of economically important species within those regions. Two economically important species will be considered for which the life-cycles are well known along with the sensitivities to OA for early life-stages: Atlantic Surf Clam in the northeast and Dungeness Crab of the northwest coast of the U.S. Other species may also be considered.

Since the program's inception, there has been great interest in determining whether beneficiaries who enter and subsequently leave Medicare health maintenance organizations (HMOs) are more or less costly than those remaining in fee-for-service (FFS) Medicare. To examine whether relatively high-cost beneficiaries disenroll from Medicare HMOs (disenrollment bias) and whether disenrollment bias varies by Medicare HMO market characteristics. In addition, we compare rates of surgical procedures and hospitalizations for ambulatory care-sensitive conditions for disenrollees and continuing FFS beneficiaries. Cross-sectional analysis of 1994 Medicare data. Medicare beneficiaries were first sampled from the 124 counties with at least 1000 Medicare HMO enrollees. From this pool, HMO disenrollees and a sample of continuing FFS beneficiaries were drawn. The FFS beneficiaries were assigned dates of "pseudodisenrollment." Expenditures and inpatient service use were compared for 6 months after disenrollment or pseudodisenrollment. The HMO disenrollees were no more likely than the continuing FFS beneficiaries to have positive total expenditures (Part A plus Part B) or Part B expenditures in the first 6 months after disenrollment. However, disenrollees were more likely to have Part A expenditures. Among beneficiaries with spending, disenrollees had higher total and Part B expenditures than continuing FFS beneficiaries. Moreover, the disparity in total and Part B spending between disenrollees and continuing FFS beneficiaries increased with HMO market penetration. Although Part A spending was higher for disenrollees with spending, it was not sensitive to changes in market share. The HMO disenrollees received more surgical procedures and were hospitalized for more of the ambulatory care-sensitive conditions than the FFS beneficiaries. On several measures, Medicare HMOs experienced favorable disenrollment relative to continuing FFS beneficiaries as recently as 1994, which increased as HMO market share increased.

This focused ethnographic study aimed to illuminate a group of South Africans' experiences of being old and of care and caring in a transitional period. With a growing number of older people in Africa, studies on the individual experiences may help to develop care which is more sensitively based on the needs for older people in a changing Southern Africa context. Data were collected through group and individual in-depth interviews and participant observations which involved 16 individuals, aged 52-76. Data were analysed using a qualitative content analysis. The study showed two interrelated themes reflections on life and ubuntu - an orientation towards others. Findings were discussed from the viewpoint of the theory of gerotranscendence, showing similarities as well as differences, possibly due to societal and cultural differences. Shortage of formal care for older people living in poor conditions in Southern Africa, gave rise to the discussion for the need of a contextualized development of gerontological care. To enhance knowledge on the theory of gerotranscendence and develop guidelines for nursing in home-based care/community-based care in a South African context may be a first step to support older people in their process towards gerotranscendence. © 2010 Blackwell Publishing Ltd.

Objectives To explain methods for data synthesis of evidence from diagnostic test accuracy (DTA) studies, and to illustrate different types of analyses that may be performed in a DTA systematic review. Methods We described properties of meta-analytic methods for quantitative synthesis of evidence. We used a DTA review comparing the accuracy of three screening questionnaires for bipolar disorder to illustrate application of the methods for each type of analysis. Results The discriminatory ability of a test is commonly expressed in terms of sensitivity (proportion of those with the condition who test positive) and specificity (proportion of those without the condition who test negative). There is a trade-off between sensitivity and specificity, as an increasing threshold for defining test positivity will decrease sensitivity and increase specificity. Methods recommended for meta-analysis of DTA studies --such as the bivariate or hierarchical summary receiver operating characteristic (HSROC) model --jointly summarise sensitivity and specificity while taking into account this threshold effect, as well as allowing for between study differences in test performance beyond what would be expected by chance. The bivariate model focuses on estimation of a summary sensitivity and specificity at a common threshold while the HSROC model focuses on the estimation of a summary curve from studies that have used different thresholds. Conclusions Meta-analyses of diagnostic accuracy studies can provide answers to important clinical questions. We hope this article will provide clinicians with sufficient understanding of the terminology and methods to aid interpretation of systematic reviews and facilitate better patient care.

Policymakers argue that emergency department (ED) visits for conditions preventable with high-quality outpatient care contribute to waste in the healthcare system. However, access to ambulatory care is uneven, especially for vulnerable populations like minorities, the poor, and those with limited health literacy. The impact of limited health literacy on ED visits that are preventable with timely, high-quality ambulatory care is unknown. The objective was to determine the association of health literacy with preventable ED visits. We conducted an observational cross-sectional study of potentially preventable ED visits (outcome) among adults (≥18 years old) in an ED serving an urban community. We assessed health literacy (predictor) through structured interviews with the Rapid Estimate of Adult Literacy in Medicine (REALM). We recorded age, sex, race, employment, payer, marital and health status, and number of comorbidities through structured interviews or electronic record review. We identified potentially preventable ED visits in the 2 years before the index ED visit by applying Agency for Healthcare Research and Quality technical specifications to identify ambulatory care sensitive conditions using ED discharge diagnoses in hospital administrative data. We used Poisson regression to evaluate the number of preventable ED visits among patients with limited (REALM < 61) versus adequate (REALM ≥ 61) health literacy after adjusting for covariates. Of 1,201 participants, 709 (59%) were female, 370 (31%) were African American, mean age was 41.6 years, and 394 (33%) had limited health literacy. Of 4,444 total ED visits, 423 (9.5%) were potentially preventable. Of these, 260 (61%) resulted in hospital admission and 163 (39%) were treat and release. After covariates were adjusted for, patients with limited literacy had 2.3 (95% confidence interval [CI] = 1.7-3.1) times the number of potentially preventable ED visits resulting in hospital admission compared to individuals with adequate health literacy, 1.4 (95% CI = 1.0-2.0) times the number of treat-and-release visits, and 1.9 (95% CI = 1.5-2.4) times the number of total preventable ED visits. Our results suggest that the ED may be an important site to deploy universal literacy-sensitive precautions and to test literacy-sensitive interventions with the goal of reducing the burden of potentially preventable ED visits on patients and the healthcare system. © 2017 by the Society for Academic Emergency Medicine.

CARE+ is a tablet PC-based computer counseling tool designed to support medication adherence and secondary HIV prevention for people living with HIV. Thirty HIV+ men and women participated in our user study to assess usability and attitudes towards CARE+. We observed them using CARE+ for the first time and conducted a semi-structured interview afterwards. Our findings suggest computer counseling may reduce social bias and encourage participants to answer questions honestly. Participants felt that discussing sensitive subjects with a computer instead of a person reduced feelings of embarrassment and being judged, and promoted privacy. Results also confirm that potential users think computers can provide helpful counseling, and that many also want human counseling interaction. Our study also revealed that tablet PC-based applications are usable by our population of mixed experience computer users. Computer counseling holds great potential for providing assessment and health promotion to individuals with chronic conditions such as HIV.

PURPOSE Some studies suggest proprietary (for-profit) hospitals are maximizing financial margins from patient care by limiting therapies or decreasing length of stay for uninsured patients. This study examines the role of insurance related to length of stay once the patient is in the hospital and risk for mortality, particularly in a for-profit environment. METHODS We undertook an analysis of hospitalizations in the National Hospital Discharge Survey (NHDS) of the 5-year period of 2003 to 2007 for patients aged 18 to 64 years (unweighted n = 849,866; weighted n = 90 million). The analysis included those who were hospitalized with both ambulatory care-sensitive conditions (ACSCs), hospitalizations considered to be preventable, and non-ACSCs. We analyzed the transformed mean length of stay between individuals who had Medicaid or all other insurance types while hospitalized and those who were hospitalized without insurance. This analysis was stratified by hospital ownership. We also examined the relationship between in-hospital mortality and insurance status. RESULTS After controlling for comorbidities; age, sex, and race/ethnicity; and hospitalizations with either an ACSC or non-ACSC diagnosis, patients without insurance tended to have a significantly shorter length of stay. Across all hospital types, the mean length of stay for ACSCs was significantly shorter for individuals without insurance (2.77 days) than for those with either private insurance (2.89 days, P = .04) or Medicaid (3.19, P <.01). Among hospitalizations for ACSCs, in-hospital mortality rate for individuals with either private insurance or Medicaid was not significantly different from the mortality rate for those without insurance. CONCLUSIONS Patients without insurance have shorter lengths of stay for both ACSCs and non-ACSCs. Future research should examine whether patients without insurance are being discharged prematurely.

Torn between dual roles: the experiences of nurse-family members when a loved one is hospitalised in a critical condition.

To understand and interpret the experiences of nurse-family members when a family member or loved one is hospitalised in a critical condition. Having a family member hospitalised with a critical illness is a traumatic stressor, often with long-term sequelae. Providing holistic care for family members who are also nurses makes the provision of care more complex because of their professional expertise; yet few studies have explored this issue. In this descriptive study, qualitative data were collected using a questionnaire and analysed using van Manen's (Researching Lived Experience: Human Science for an Action Sensitive Pedagogy, 1990, State University of New York Press, London, ON) six-step approach. Twenty nurse-family members completed an online questionnaire in June 2013. Qualitative findings from 19 participants were included in the analysis. The phenomenological analysis approach described by van Manen (Researching Lived Experience: Human Science for an Action Sensitive Pedagogy, 1990, State University of New York Press, London, ON) was used to describe and interpret nurse-family member experiences. Nurse-family members experience significant dual role conflicts between their personal and professional personas due to their specialised knowledge, need for watchfulness and competing expectations. Our findings describe how dual role conflicts developed and were managed, and reveal the resultant emotional toll and psychological distress as nurse-family members struggled to resolve these conflicts. Nurse-family members require a different type of care than general public family members, yet their unique needs are often unmet, leading to increased anxiety and distress that could potentially be minimised. An increased awareness and emphasis on the nurse-family member experience can ensure health care professionals are better placed to provide appropriate and targeted care to minimise distressing dual role conflicts. There is a need for targeted and specialised communication appropriate to each nurse-family members' needs and level of understanding, and to clarify expectations to ensure nurse-family members' professional knowledge and skills are recognised and respected without being exploited. © 2015 John Wiley & Sons Ltd.

2009-07-31

Federally qualified community health centers (CHCs) and rural health clinics (RHCs) are intended to provide access to care for vulnerable populations. While some research has explored the effects of CHCs on population health, little information exists regarding RHC effects. We sought to clarify the contribution that CHCs and RHCs may make to the accessibility of primary health care, as measured by county-level rates of hospitalization for ambulatory care sensitive (ACS) conditions. We conducted an ecologic analysis of the relationship between facility presence and county-level hospitalization rates, using 2002 discharge data from eight states within the US (579 counties). Counties were categorized by facility availability: CHC(s) only, RHC(s) only, both (CHC and RHC), and neither. US Agency for Healthcare Research and Quality definitions were used to identify ACS diagnoses. Discharge rates were based on the individual's county of residence and were obtained by dividing ACS hospitalizations by the relevant county population. We calculated ACS rates separately for children, working age adults, and older individuals, and for uninsured children and working age adults. To ensure stable rates, we excluded counties having fewer than 1,000 residents in the child or working age adult categories, or 500 residents among those 65 and older. Multivariate Poisson analysis was used to calculate adjusted rate ratios. Among working age adults, rate ratio (RR) comparing ACS hospitalization rates for CHC-only counties to those of counties with neither facility was 0.86 (95% Confidence Interval, CI, 0.78-0.95). Among older adults, the rate ratio for CHC-only counties compared to counties with neither facility was 0.84 (CI 0.81-0.87); for counties with both CHC and RHC present, the RR was 0.88 (CI 0.84-0.92). No CHC/RHC effects were found for children. No effects were found on estimated hospitalization rates among uninsured populations. Our results suggest that CHCs and RHCs may play a useful role in providing access to primary health care. Their presence in a county may help to limit the county's rate of hospitalization for ACS diagnoses, particularly among older people.

[Health management as part of leadership in public administration].

PubMed

Matyssek, A K

2012-02-01

Leadership includes two tasks within public administration: leading employees by creating healthy working conditions and being led by others. The basis of leading others in a healthy way means dealing with oneself in a healthy manner; this includes typical healthy behavior (i.e., physical activity, improved nutrition, not smoking), which allows for recovery by a good work-life balance and a sensitive dealing with one's own limits. Given these conditions of healthy self care, managers are able to act as role models and lead their employees in a healthy manner. Leading in a healthy manner means showing appreciation, being interested in the employees ("caring"), integrating them in decision-making, allowing transparency, improving the working atmosphere, and finally reducing stress and increasing resources. The latter includes social support, which decreases the danger of employees burning out. The article presents the concept of a 2-day training that is designed for managers in order to raise their awareness for duties related to health management in public administration.

Haber, Susan G; Wensky, Suzanne G; McCall, Nancy T

2017-04-01

To examine the association among nursing home residents between strength of relationship with a primary care provider (PCP) and inpatient hospital and emergency room (ER) utilization. Medicare administrative data for beneficiaries residing in a nursing home between July 2007 and June 2009 were used in multivariate analyses controlling for beneficiary, nursing home, and market characteristics to assess the association between two measures-percentage of months with a PCP visit and whether the patient maintained the same usual source of care after nursing home admission-and hospital admissions and ER visits for all causes and for ambulatory care sensitive conditions (ACSCs). Both measures of strength of patient-provider relationships were associated with fewer inpatient admissions and ER visits, except regularity of PCP visits and ACSC ER visits. Policy makers should consider increasing the strength of nursing home resident and PCP relationships as one strategy for reducing inpatient and ER utilization.

Surface acoustic wave (SAW) sensors can rapidly detect Ebola antigens at the point-of-care without the need for added reagents, sample processing, or specialized personnel. This preliminary study demonstrates SAW biosensor detection of the Ebola virus in a concentration-dependent manner. The detection limit with this methodology is below the average level of viremia detected on the first day of symptoms by PCR. We observe a log-linear sensor response for highly fragmented Ebola viral particles, with a detection limit corresponding to 1.9 × 104 PFU/mL prior to virus inactivation. We predict greatly improved sensitivity for intact, infectious Ebola virus. This point-of-care methodology has the potential to detect Ebola viremia prior to symptom onset, greatly enabling infection control and rapid treatment. This biosensor platform is powered by disposable AA batteries and can be rapidly adapted to detect other emerging diseases in austere conditions. PMID:25875186

There is an ever-growing trend toward more patient involvement in making health care decisions. This trend has been accompanied by the development of "informed decision-making" interventions to help patients become more engaged and comfortable with making these decisions. We describe the effects of a prostate cancer screening decision aid on knowledge, beliefs about screening, risk perception, control preferences, decisional conflict, and decisional anxiety. Data were collected from 200 males aged 50-70 years in the general population who randomly were assigned to exposure to the decision aid or no exposure as a control condition. A Solomon four-group design was used to test for possible pretest sensitization effects and to assess the effects of exposure to the decision aid. No significant pretest sensitization effects were found. Analysis of the exposure effects found that knowledge increased significantly for those exposed to the decision aid compared with those unexposed. Exposure to the decision aid also had some influence on decreasing both decisional conflict and decisional anxiety. Decision aids can play an important role in increasing patients' knowledge and decreasing anxiety when asked to make health care decisions.

We conducted a community-based randomized control trial with intent-to-treat analysis on Promoting First Relationships® (PFR), a 10-week home visiting program. The study included 247 families with 10- to 24-month-old children who had a recent, open child protective services investigation of child maltreatment. Families were randomly assigned to receive either the 10-week home visiting PFR service or a telephone-based, three-call resource and referral (R&R) service. Across postintervention time points, parents in the PFR condition scored higher than families in the R&R condition in parent understanding of toddlers' social emotional needs (d = .35) and observed parental sensitivity (d = .20). Children in the PFR condition scored lower than children in the comparison condition on an observational measure of atypical affective communication (d = .19) and were less likely than children in the comparison group to be placed into foster care through 1-year postintervention (6% vs. 13%, p = .042). No significant differences were found on measures of parenting stress or child social-emotional competence, behavior problems, or secure base behavior. Overall, the results show support for the promise of PFR as an intervention for enhancing parent sensitivity and preventing child removals for families in the child welfare system. © The Author(s) 2016.

Central sensitivity syndromes: a new paradigm and group nosology for fibromyalgia and overlapping conditions, and the related issue of disease versus illness.

2008-06-01

To discuss the current terminologies used for fibromyalgia syndrome (FMS) and related overlapping conditions, to examine if central sensitivity syndromes (CSS) is the appropriate nosology for these disorders, and to explore the issue of disease versus illness. A literature search was performed through PubMed, Web of Science, and ScienceDirect using a number of keywords, eg, functional somatic syndromes, somatoform disorders, medically unexplained symptoms, organic and nonorganic, and diseases and illness. Relevant articles were then reviewed and representative ones cited. Terminologies currently used for CSS conditions predominantly represent a psychosocial construct and are inappropriate. On the other hand, CSS seems to be the logical nosology based on a biopsychosocial model. Such terms as "medically unexplained symptoms," "somatization," "somatization disorder," and "functional somatic syndromes" in the context of CSS should be abandoned. Given current scientific knowledge, the concept of disease-illness dualism has no rational basis and impedes proper patient-physician communication, resulting in poor patient care. The concept of CSS is likely to promote research, education, and proper patient management. CSS seems to be a useful paradigm and an appropriate terminology for FMS and related conditions. The disease-illness, as well as organic/non-organic dichotomy, should be rejected.

Tension tests on graphite/epoxy composites were performed to determine the influence of various quality control variables on failure strength as a function of moisture and moderate temperatures. The extremely high and low moisture contents investigated were found to have less effect upon properties than did temperature or the quality control variables of specimen flaws and prepreg batch to batch variations. In particular, specimen flaws were found to drastically reduce the predicted strength of the composite, whereas specimens from different batches of prepreg displayed differences in strength as a function of temperature and extreme moisture exposure. The findings illustrate the need for careful specimen preparation, studies of flaw sensitivity, and careful quality control in any study of composite materials.

Quantitatively calibrated annular dark field scanning transmission electron microscopy (ADF-STEM) imaging experiments were compared to frozen phonon multislice simulations adapted to include chemical bonding effects. Having carefully matched simulation parameters to experimental conditions, a depth-dependent bonding effect was observed for high-angle ADF-STEM imaging of aluminum nitride. This result is explained by computational predictions, systematically examined in the preceding portion of this study, showing the propagation of the converged STEM beam to be highly sensitive to net interatomic charge transfer. Thus, although uncertainties in experimental conditions and simulation accuracy remain, the computationally predicted experimental bonding effect withstands the experimental testing reportedmore » here.« less

2016-01-01

Interest in wilderness travel has been increasing in women of all ages and can lead to multiple health benefits. In order to optimize a woman's experience in the wilderness, providers should be aware of both common and special conditions unique to women that may be impacted by wilderness travel. Both anatomic and physiologic differences set women apart from men and should be carefully considered in a wilderness setting. Special conditions pertaining to women in the wilderness include high altitude exposure and temperature sensitivity. Before wilderness travel, each patient should complete a physical examination, review medical history with a provider, and receive an overview of counseling for their desired area of travel.

We present combined surface-enhanced stimulated Raman scattering (SE-SRS) and surface-enhanced coherent anti-Stokes Raman scattering (SE-CARS) measurements on individual plasmonic antennas dressed with bipyridyl-ethylene molecules. By carefully optimizing the conditions for performing SE-SRS experiments, we have obtained stable and reproducible molecular surface-enhanced SRS spectra from single nano-antennas. Using surface-enhanced Raman scattering (SERS) and transmission electron microscopy of the same antennas, we confirm that the observed SE-SRS signals originate from only one or a few molecules. We highlight the physics of surface enhancement in the context of coherent Raman scattering and derive sensitivity parameters under the relevant conditions. The implications of single molecule SRS measurements are discussed.

This study examined maternal sensitivity in response to toddler distress in relation to mothers' childhood care and control experiences with parents, maternal depression, and maternal anger. Fifty-two mothers and infants participated. Mothers reported childhood care and control experiences prenatally. At 2½ years, mothers reported depressive symptoms and anger on questionnaires, and reported maternal behavior in a daily diary for 1 week, yielding ratings of maternal sensitivity to fear and anger. Results were as follows: (a) Mothers' acceptance during childhood correlated negatively with both maternal depression and maternal anger, and positively with maternal sensitivity to fear at 2½ years; (b) maternal anger mediated the association between childhood care and maternal sensitivity to fear at 2½ years; and (c) the interaction of maternal and paternal control during childhood predicted maternal sensitivity to anger at 2½ years, controlling for maternal education. When maternal control was low, paternal control was positively associated with maternal sensitivity to anger whereas when maternal control was high, paternal control was negatively associated with maternal sensitivity to anger. Results are discussed in relation to prior studies, with particular emphasis on attachment theory. Implications for preventive intervention efforts are considered.

2016-04-01

To determine the accuracy of International Statistical Classification of Disease and Related Health Problems, 10th Revision (ICD-10) coding system in identifying comorbidities and infectious conditions using data from a Thai university hospital administrative database. A retrospective cross-sectional study was conducted among patients hospitalized in six general medicine wards at Siriraj Hospital. ICD-10 code data was identified and retrieved directly from the hospital administrative database. Patient comorbidities were captured using the ICD-10 coding algorithm for the Charlson comorbidity index. Infectious conditions were captured using the groups of ICD-10 diagnostic codes that were carefully prepared by two independent infectious disease specialists. Accuracy of ICD-10 codes combined with microbiological dataf or diagnosis of urinary tract infection (UTI) and bloodstream infection (BSI) was evaluated. Clinical data gathered from chart review was considered the gold standard in this study. Between February 1 and May 31, 2013, a chart review of 546 hospitalization records was conducted. The mean age of hospitalized patients was 62.8 ± 17.8 years and 65.9% of patients were female. Median length of stay [range] was 10.0 [1.0-353.0] days and hospital mortality was 21.8%. Conditions with ICD-10 codes that had good sensitivity (90% or higher) were diabetes mellitus and HIV infection. Conditions with ICD-10 codes that had good specificity (90% or higher) were cerebrovascular disease, chronic lung disease, diabetes mellitus, cancer HIV infection, and all infectious conditions. By combining ICD-10 codes with microbiological results, sensitivity increased from 49.5 to 66%for UTI and from 78.3 to 92.8%for BS. The ICD-10 coding algorithm is reliable only in some selected conditions, including underlying diabetes mellitus and HIV infection. Combining microbiological results with ICD-10 codes increased sensitivity of ICD-10 codes for identifying BSI. Future research is needed to improve the accuracy of hospital administrative coding system in Thailand.

Food insecurity is associated with high health care expenditures, but the effectiveness of food insecurity interventions on health care costs is unknown. To determine whether the Supplemental Nutrition Assistance Program (SNAP), which addresses food insecurity, can reduce health care expenditures. This is a retrospective cohort study of 4447 noninstitutionalized adults with income below 200% of the federal poverty threshold who participated in the 2011 National Health Interview Survey (NHIS) and the 2012-2013 Medical Expenditure Panel Survey (MEPS). Self-reported SNAP participation in 2011. Total health care expenditures (all paid claims and out-of-pocket costs) in the 2012-2013 period. To test whether SNAP participation was associated with lower subsequent health care expenditures, we used generalized linear modeling (gamma distribution, log link, with survey design information), adjusting for demographics (age, gender, race/ethnicity), socioeconomic factors (income, education, Social Security Disability Insurance disability, urban/rural), census region, health insurance, and self-reported medical conditions. We also conducted sensitivity analyses as a robustness check for these modeling assumptions. A total of 4447 participants (2567 women and 1880 men) were enrolled in the study, mean (SE) age, 42.7 (0.5) years; 1889 were SNAP participants, and 2558 were not. Compared with other low-income adults, SNAP participants were younger (mean [SE] age, 40.3 [0.6] vs 44.1 [0.7] years), more likely to have public insurance or be uninsured (84.9% vs 67.7%), and more likely to be disabled (24.2% vs 10.6%) (P < .001 for all). In age- and gender-adjusted models, health care expenditures between those who did and did not participate in SNAP were similar (difference, $34; 95% CI, -$1097 to $1165). In fully adjusted models, SNAP was associated with lower estimated annual health care expenditures (-$1409; 95% CI, -$2694 to -$125). Sensitivity analyses were consistent with these results, also indicating that SNAP participation was associated with significantly lower estimated expenditures. SNAP enrollment is associated with reduced health care spending among low-income American adults, a finding consistent across several analytic approaches. Encouraging SNAP enrollment among eligible adults may help reduce health care costs in the United States.

Background Syphilis point-of-care tests may reduce morbidity and ongoing transmission by increasing the proportion of people rapidly treated. Syphilis stage and co-infection with HIV may influence test performance. We evaluated four commercially available syphilis point-of-care devices in a head-to-head comparison using sera from laboratories in Australia. Methods Point-of-care tests were evaluated using sera stored at Sydney and Melbourne laboratories. Sensitivity and specificity were calculated by standard methods, comparing point-of-care results to treponemal immunoassay (IA) reference test results. Additional analyses by clinical syphilis stage, HIV status, and non-treponemal antibody titre were performed. Non-overlapping 95% confidence intervals (CI) were considered statistically significant differences in estimates. Results In total 1203 specimens were tested (736 IA-reactive, 467 IA-nonreactive). Point-of-care test sensitivities were: Determine 97.3%(95%CI:95.8–98.3), Onsite 92.5%(90.3–94.3), DPP 89.8%(87.3–91.9) and Bioline 87.8%(85.1–90.0). Specificities were: Determine 96.4%(94.1–97.8), Onsite 92.5%(90.3–94.3), DPP 98.3%(96.5–99.2), and Bioline 98.5%(96.8–99.3). Sensitivity of the Determine test was 100% for primary and 100% for secondary syphilis. The three other tests had reduced sensitivity among primary (80.4–90.2%) compared to secondary syphilis (94.3–98.6%). No significant differences in sensitivity were observed by HIV status. Test sensitivities were significantly higher among high-RPR titre (RPR≥8) (range: 94.6–99.5%) than RPR non-reactive infections (range: 76.3–92.9%). Conclusions The Determine test had the highest sensitivity overall. All tests were most sensitive among high-RPR titre infections. Point-of-care tests have a role in syphilis control programs however in developed countries with established laboratory infrastructures, the lower sensitivities of some tests observed in primary syphilis suggest these would need to be supplemented with additional tests among populations where syphilis incidence is high to avoid missing early syphilis cases.

Older South Asian patient and carer perceptions of culturally sensitive care in a community hospital setting.

Clegg, Angie

2003-03-01

This study describes the application of grounded theory to establish older, south Asian patient and carer views of service delivery in the UK. The purpose of the study was to inform the development of culturally sensitive services by defining the concept of cultural sensitivity from a user/carer perspective. The study took place in two community hospitals providing nurse-led intermediate care to a culturally diverse inner city population. Fifty-five per cent of the inner city population is of south Asian origin. Admissions to intermediate care, however, do not reflect the demography. Recent reports commissioned by the Department of Health highlight the failure of the National Health Service in England to provide culturally sensitive services to black and Asian patients. The Department of Health is trying to redress this inequality providing policy guidance for improving access and cultural sensitivity in the British health care system. There is little existing empirical evidence, however, to clarify the concept of culturally sensitive care. Patients and carers in this study described culturally appropriate care as that which respects individuality, creates mutual understanding, caters for spiritual need and maintains dignity. Older south Asian patients and their carers identified respect, understanding, spirituality and dignity as central to their conceptualization of cultural sensitivity. Their focus was on the nature of human relationships and their ability to interact in a positive way with staff. The findings of this small piece of empirical research are limited by the sample size (four patients and three carers), but illustrate that cultural sensitivity, although complex, can be defined. This then provides a basis for developing appropriate care strategies. One universal principle explicit in this research was that to be sensitive to culture staff must challenge their own assumptions and develop an understanding of the many layers of culture and subculture with which they are dealing. The starting point for any service is to understand the expectations of its users and to seek out and manage areas of conflict between organizational values and individuals' cultural requirements.

The long-term outcomes of patients undergoing interventions for congenital heart disease (CHD) remain largely unknown. We linked the Pediatric Cardiac Care Consortium (PCCC) with the National Death Index (NDI) and the United Network for Organ Sharing Dataset (UNOS) registries to study mortality and transplant occurring up to 32 years postintervention. The objective of the current analysis was to determine the sensitivity of this linkage in identifying patients who are known to have died or undergone heart transplant. We used direct identifiers from 59 324 subjects registered in the PCCC between 1982 and 2003 to test for completeness of case ascertainment of subjects with known vital and heart transplant status by linkage with the NDI and UNOS registries. Of the 4612 in-hospital deaths, 3873 were identified by the NDI as "true" matches for a sensitivity of 84.0% (95% CI, 82.9-85.0). There was no difference in sensitivity across 25 congenital cardiovascular conditions after adjustment for age, sex, race, presence of first name, death year, and residence at death. Of 455 known heart transplants in the PCCC, there were 408 matches in the UNOS registry, for a sensitivity of 89.7% (95% CI, 86.9-92.3). An additional 4851 deaths and 363 transplants that occurred outside the PCCC were identified through 2014. The linkage of the PCCC with the NDI and UNOS national registries is feasible with a satisfactory sensitivity. This linkage provides a conservative estimate of the long-term death and heart transplant events in this cohort. © 2016 The Authors.

In increasingly globalized societies, patient-centered cancer care requires culture-sensitive approaches in order to ensure patients well-being. While migrant patients' needs are frequently reported in the literature, staff members' perception of work with migrant patients, associated challenges, or individual work approaches are largely unknown. This study addresses this research gap through qualitative exploration of experiences of multicultural health care professionals in supportive oncology and palliative care, working with patients from different cultural backgrounds. This study aims to understand staff experience of the impact of culture on cancer care. This study was conducted at the Medical University of Vienna, including staff from different settings of oncology and palliative care, in different professional positions, and with a range of individual migration backgrounds. Semistructured interviews were conducted with 21 staff members working with patients from different cultural backgrounds. Interviews explored views on the impact of culture on care were audio-taped, transcribed, and analyzed using a rigorous method of thematic analysis, enhanced with grounded theory techniques. Interviews revealed 4 key topics: culture-specific differences, assumed reasons for differences, consequences of multicultural care, and tools for culture-sensitive care. Strategies to better deal with migrant patients and their families were suggested to improve work satisfaction amongst staff. This study identifies relevant staff challenges in work with migrant patients. Concrete suggestions for improvement include measures on an organizational level, team level, and personal tools. The suggested measures are applicable to improve work satisfaction and culture-sensitive care not only in cancer care but also in other areas of medicine. Copyright © 2016 John Wiley & Sons, Ltd.

The Rales Health Center is a comprehensive school-based health center at an urban elementary/middle school. Rales Health Center provides a full range of pediatric services using an enriched staffing model consisting of pediatrician, nurse practitioner, registered nurses, and medical office assistant. This staffing model provides greater care but costs more than traditional school-based health centers staffed by part-time nurses. The objective was to analyze the cost benefit of Rales Health Center enhanced staffing model compared with a traditional school-based health center (standard care), focusing on asthma care, which is among the most prevalent chronic conditions of childhood. In 2016, cost-benefit analysis using a decision tree determined the net social benefit of Rales Health Center compared with standard care from the U.S. societal perspective based on the 2015-2016 academic year. It was assumed that Rales Health Center could handle greater patient throughput related to asthma, decreased prescription costs, reduced parental resources in terms of missed work time, and improved student attendance. Univariate and multivariate probabilistic sensitivity analyses were conducted. The expected cost to operate Rales Health Center was $409,120, compared with standard care cost of $172,643. Total monetized incremental benefits of Rales Health Center were estimated to be $993,414. The expected net social benefit for Rales Health Center was $756,937, which demonstrated substantial societal benefit at a return of $4.20 for every dollar invested. This net social benefit estimate was robust to sensitivity analyses. Despite the greater cost associated with the Rales Health Center's enhanced staffing model, the results of this analysis highlight the cost benefit of providing comprehensive, high-quality pediatric care in schools, particularly schools with a large proportion of underserved students.

Electronic Medical Records (EMRs) are increasingly used in the provision of primary care and have been compiled into databases which can be utilized for surveillance, research and informing practice. The primary purpose of these records is for the provision of individual patient care; validation and examination of underlying limitations is crucial for use for research and data quality improvement. This study examines and describes the validity of chronic disease case definition algorithms and factors affecting data quality in a primary care EMR database. A retrospective chart audit of an age stratified random sample was used to validate and examine diagnostic algorithms applied to EMR data from the Manitoba Primary Care Research Network (MaPCReN), part of the Canadian Primary Care Sentinel Surveillance Network (CPCSSN). The presence of diabetes, hypertension, depression, osteoarthritis and chronic obstructive pulmonary disease (COPD) was determined by review of the medical record and compared to algorithm identified cases to identify discrepancies and describe the underlying contributing factors. The algorithm for diabetes had high sensitivity, specificity and positive predictive value (PPV) with all scores being over 90%. Specificities of the algorithms were greater than 90% for all conditions except for hypertension at 79.2%. The largest deficits in algorithm performance included poor PPV for COPD at 36.7% and limited sensitivity for COPD, depression and osteoarthritis at 72.0%, 73.3% and 63.2% respectively. Main sources of discrepancy included missing coding, alternative coding, inappropriate diagnosis detection based on medications used for alternate indications, inappropriate exclusion due to comorbidity and loss of data. Comparison to medical chart review shows that at MaPCReN the CPCSSN case finding algorithms are valid with a few limitations. This study provides the basis for the validated data to be utilized for research and informs users of its limitations. Analysis of underlying discrepancies provides the ability to improve algorithm performance and facilitate improved data quality.

Assessing sensitivity and specificity of the Manchester Triage System in the evaluation of acute coronary syndrome in adult patients in emergency care: a systematic review protocol.

The objective of this review is to assess the sensitivity and specificity of the Manchester Triage System in the evaluation of adult patients with acute coronary syndrome in emergency departments. Acute coronary syndrome (ACS) is a group of clinical conditions that include myocardial infarction with or without elevation of the ST segment and unstable angina. The term acute myocardial infarction (AMI) can be applied when there is evidence of myocardium necrosis with a clinical sign compatible with myocardial ischaemia. Acute myocardial infarction can be identified using clinical methods including electrocardiography (ECG), elevation in myocardium necrosis biomarkers, and imaging. Acute myocardial infarction is one of the leading causes of death and disability worldwide, and may be the first manifestation of coronary artery disease.Estimating the prevalence of coronary diseases in the general population is quite a complex task. In 2010, the prevalence of coronary diseases was reported as 6.4% among the general population in the United States.One of the main manifestations of ACS is chest pain. However, even in the presence of this typical symptom, early diagnosis of ACS is a challenge for health care professionals who initially attend to these patients. Several authors have indicated the importance and difficulty of recognizing chest pain of cardiac origin, where immediate medical attention is required.Triage, or risk classification, is a clinical management tool used in emergency services to guide patient flow when the need for medical attention exceeds that available. The Manchester Triage Group was developed in 1994 in the United Kingdom. The aim was to establish a consensus among physicians and nurses in the emergency room by creating a triage pattern focused on the development of the following:Thus, the Manchester Triage System (MTS) was created. The MTS simplifies the clinical management of each patient, and consequently, the whole service, by utilizing a system that defines the clinical priority for adults and children. The assessment of clinical priority needs to be fast; therefore, it is separated from the process of medical diagnosis. Restricting the time allocated for patient classification prevents an attempt to make a medical diagnosis at the time of classification.The main goal of the MTS is to set a time limit for each patient to be attended to safely, that is, with no risk to the patient's health. One of the main principles of the system is the higher the perceived risk to the patient's health, the shorter the waiting time for medical attendance. The MTS comprises a scale of five priority levels ().(Table is included in full-text article.)The MTS is composed of 52 distinct flowcharts that "guide" the triage decision-making process. Based on the main presenting symptom of the patient seeking emergency care, the health care professional must choose one of the 52 flowcharts in order to proceed with evaluation. Classification into one of the five clinical priority levels is set for each patient using the selected flowchart.The lack of a risk classification system within an emergency room implies attendance on a first-come, first-served basis, which in many cases may jeopardize a patient's safety, as patients whose health status is more unstable or severe are not prioritized.The MTS is a tool that aims to define the degree of severity and associated safe waiting time for patients in the emergency department, establishing an order of priority for medical care. It determines the clinical priority of every patient who comes to the emergency department. It is possible to evaluate the sensitivity and specificity of the MTS by calculating the frequency of appropriately assigned clinical priority levels to patients presenting at the emergency department.A "diagnostic test" can be understood as a laboratory or imaging test: however, the concepts related to "test" also apply to clinical information from other findings, such as physical examination and patient history. The sensitivity of a test is understood as the capacity of the test to detect individuals who present with a particular condition, or the proportion of individuals with a particular condition who have been tested positive for this condition (true positive). Highly sensitive tests can be used at the beginning of the diagnostic process, when a great number of possibilities are being considered, with the intention of excluding as many options as possible. The specificity of a test is defined as the capacity of the test to identify individuals who do not have a particular medical condition, or the proportion of individuals without the condition who have a negative test (true negative). A triage system that presents a good sensitivity can minimize the occurrence of undertriage, the same way, systems with suitable specificity can avoid the occurrence of overtriage.The assessment of patients with ACS suspected using the MTS, can occur through different flow charts, since the patient does not always have typical symptoms and concerns such as chest pain as the main complaint. For this reason, in addition to the flowchart "chest pain", other flowcharts, including "shortness of breath in adults", "unwell adult", "collapsed adult", and "palpitations", enable distinguishing chest pain and other urgent conditions from non-urgent conditions, and can assist the appraiser to establish the highest priority level to treat patients with these urgent conditions.According to the algorithm from the American Heart Association, every patient who presents symptoms of chest discomfort suggestive of ischaemia must receive medical attention within 10 minutes. Therefore, in order to recognize patients in those conditions, the health care professional applying MTS must establish priority levels of "red" or "orange", thereby setting a safe waiting time for these patients.Although there are well-established criteria for the prioritization of patients with suspected ACS, several studies have reported the difficulties of evaluating patients with these conditions. Various factors can interfere with the outcome of this process, such as atypical presentation of symptoms, AMI classification, patient age, and professional skill.Primary studies have addressed the issue from different perspectives. Studies have been conducted to evaluate the ability of nurses using MTS to detect high-risk patients with chest pain, the impact of MTS on short-term mortality in AMI, and the sensitivity and specificity of MTS for patients with ACS, and to assess whether the MTS was used effectively in patients admitted to the hospital with a diagnosis of acute coronary syndrome.These studies concluded that use of the MTS by nurses is a sensitive method for identifying high risk cardiac chest pain, but further studies are required to assess whether additional training can improve the sensitivity of MTS. The MTS safeguards patients with typical AMI presentation and ST elevation during myocardial infarction, and who are under 70 years of age. The MTS has a high sensitivity in prioritization (immediate/very urgent) of patients with ACS. Additionally, most patients admitted for ACS are initially triaged as "orange" or "yellow", an indication for prompt assessment in the emergency department. This has a positive effect on time to first medical assessment, but has no effect on time to hospital admission.A systematic review addressing a similar theme was published. The review evaluated the efficacy of MTS for all groups of patients and included studies that evaluated the MTS in relation to different outcomes. This proposed review is different as it will include primary studies with a specific sub-population (patients with ACS). Another important difference lies in the fact that the published review did not include critical appraisal of the primary studies included in review. A systematic review that synthesizes the available evidence on the sensitivity of MTS to evaluate patients with an ACS medical diagnosis is necessary to guide decisions related to the use or adoption of the instrument, as well as providing data that can contribute to improvements to the system.

To explore how gender appears in the stories of self-told by men and women undergoing rehabilitation for chronic muscle pain. The material, which consists of qualitative interviews with 10 men and 6 women with chronic neck pain, was analyzed from a gender sensitive perspective using narrative method. The analysis was inspired by Arthur Frank's typologies of illness narratives (restitution, chaos and quest). The women's stories displayed selves that were actively trying to transcend their former identity and life conditions, in which their pain was embedded. Their stories tended to develop from "chaos", towards a quest narrative with a more autonomous self. The selves in the men's stories appeared to be actively seeking a solution to the pain within a medical context. Framed as a restitution narrative, rooted in a biomedical model of disease, the voice often heard in the men's stories was of a self-dependent on future health care. Our findings contribute greater nuance to a dominant cultural conception that men are more independent than women in relation to health care. Understanding the significance of gender in the construction of selves in stories of chronic pain may help to improve the health care offered to patients suffering from chronic pain. Implications for Rehabilitation Patients tell stories that powerfully communicate their particular illness experiences. Cultural expectations of femininity and masculinity play a significant role with regard to how the patients construct their stories, which may be important to health professionals' perceptions of the patients' problem. Health care professionals should listen carefully to the patient's own story and be sensitive to the significance of gender when trying to understand these people's health problem.

Natural emulsifiers - Biosurfactants, phospholipids, biopolymers, and colloidal particles: Molecular and physicochemical basis of functional performance.

There is increasing consumer pressure for commercial products that are more natural, sustainable, and environmentally friendly, including foods, cosmetics, detergents, and personal care products. Industry has responded by trying to identify natural alternatives to synthetic functional ingredients within these products. The focus of this review article is on the replacement of synthetic surfactants with natural emulsifiers, such as amphiphilic proteins, polysaccharides, biosurfactants, phospholipids, and bioparticles. In particular, the physicochemical basis of emulsion formation and stabilization by natural emulsifiers is discussed, and the benefits and limitations of different natural emulsifiers are compared. Surface-active polysaccharides typically have to be used at relatively high levels to produce small droplets, but the droplets formed are highly resistant to environmental changes. Conversely, surface-active proteins are typically utilized at low levels, but the droplets formed are highly sensitive to changes in pH, ionic strength, and temperature. Certain phospholipids are capable of producing small oil droplets during homogenization, but again the droplets formed are highly sensitive to changes in environmental conditions. Biosurfactants (saponins) can be utilized at low levels to form fine oil droplets that remain stable over a range of environmental conditions. Some nature-derived nanoparticles (e.g., cellulose, chitosan, and starch) are effective at stabilizing emulsions containing relatively large oil droplets. Future research is encouraged to identify, isolate, purify, and characterize new types of natural emulsifier, and to test their efficacy in food, cosmetic, detergent, personal care, and other products.

Tunable reverse-biased graphene/silicon heterojunction Schottky diode sensor.

2014-04-24

A new chemical sensor based on reverse-biased graphene/Si heterojunction diode has been developed that exhibits extremely high bias-dependent molecular detection sensitivity and low operating power. The device takes advantage of graphene's atomically thin nature, which enables molecular adsorption on its surface to directly alter graphene/Si interface barrier height, thus affecting the junction current exponentially when operated in reverse bias and resulting in ultrahigh sensitivity. By operating the device in reverse bias, the work function of graphene, and hence the barrier height at the graphene/Si heterointerface, can be controlled by the bias magnitude, leading to a wide tunability of the molecular detection sensitivity. Such sensitivity control is also possible by carefully selecting the graphene/Si heterojunction Schottky barrier height. Compared to a conventional graphene amperometric sensor fabricated on the same chip, the proposed sensor demonstrated 13 times higher sensitivity for NO₂ and 3 times higher for NH₃ in ambient conditions, while consuming ∼500 times less power for same magnitude of applied voltage bias. The sensing mechanism based on heterojunction Schottky barrier height change has been confirmed using capacitance-voltage measurements. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Traditional in vitro diagnostics requires specialized laboratories and costly instrumentation, both for the amplification of nucleic acid targets (usually achieved by PCR) and for the assay readout, often based on fluorescence. We are developing hybrid nanomaterials-based sensors for the rapid and low-cost diagnosis of various disease biomarkers, for applications in portable platforms for diagnostics at the point-of-care. To this aim, we exploited the size and distancedependent optical properties of gold nanoparticles (AuNPs) to achieve colorimetric detection. Moreover, in order to avoid the complexity of thermal cycles associated to traditional PCR, the design of our systems includes signal amplification schemes, achieved by the use of enzymes (nucleases, helicase) or DNAzymes. Focused on instrument-free and sensitive detection, we carefully combined the intrinsic sensitivity by multivalency of functionalized AuNPs with isothermal and non-stringent enzyme-aided reaction conditions, controlled AuNPs aggregates, universal reporters and magnetic microparticles, the latter used both as a substrate and as a means for the colorimetric detection. We obtained simple and robust assays for the sensitive (pM range or better) naked-eye detection of cancer or infectious diseases (HPV, HCV) biomarkers, requiring no instrumentation except for a simple heating plate. Finally, we are also developing non-medical applications of these bio-nanosensors, such as in the development of on-field rapid tests for the detection of pollutants and other food and water contaminants.

Early Life Experiences and Exercise Associate with Canine Anxieties.

Personality and anxiety disorders across species are affected by genetic and environmental factors. Shyness-boldness personality continuum exists across species, including the domestic dog, with a large within- and across-breed variation. Domestic dogs are also diagnosed for several anxiety-related behavioral conditions, such as generalized anxiety disorders, phobias, and separation anxiety. Genetic and environmental factors contributing to personality and anxiety are largely unknown. We collected questionnaire data from a Finnish family dog population (N = 3264) in order to study the associating environmental factors for canine fearfulness, noise sensitivity, and separation anxiety. Early life experiences and exercise were found to associate with anxiety prevalence. We found that fearful dogs had less socialization experiences (p = 0.002) and lower quality of maternal care (p < 0.0001) during puppyhood. Surprisingly, the largest environmental factor associating with noise sensitivity (p < 0.0001) and separation anxiety (p = 0.007) was the amount of daily exercise; dogs with noise sensitivity and separation anxiety had less daily exercise. Our findings suggest that dogs share many of the same environmental factors that contribute to anxiety in other species as well, such as humans and rodents. Our study highlights the importance of early life experiences, especially the quality of maternal care and daily exercise for the welfare and management of the dogs, and reveals important confounding factors to be considered in the genetic characterization of canine anxiety.

The goal of this study was to test whether the volume of coal mining was related to population hospitalization risk for diseases postulated to be sensitive or insensitive to coal mining by-products. The study was a retrospective analysis of 2001 adult hospitalization data (n = 93,952) for West Virginia, Kentucky, and Pennsylvania, merged with county-level coal production figures. Hospitalization data were obtained from the Health Care Utilization Project National Inpatient Sample. Diagnoses postulated to be sensitive to coal mining by-product exposure were contrasted with diagnoses postulated to be insensitive to exposure. Data were analyzed using hierarchical nonlinear models, controlling for patient age, gender, insurance, comorbidities, hospital teaching status, county poverty, and county social capital. Controlling for covariates, the volume of coal mining was significantly related to hospitalization risk for two conditions postulated to be sensitive to exposure: hypertension and chronic obstructive pulmonary disease (COPD). The odds for a COPD hospitalization increased 1% for each 1462 tons of coal, and the odds for a hypertension hospitalization increased 1% for each 1873 tons of coal. Other conditions were not related to mining volume. Exposure to particulates or other pollutants generated by coal mining activities may be linked to increased risk of COPD and hypertension hospitalizations. Limitations in the data likely result in an underestimate of associations.

The current Ebola outbreak in West Africa has affected more people than all previous outbreaks combined. The current diagnostic method of choice, quantitative polymerase chain reaction, requires specialized conditions as well as specially trained technicians. Insufficient testing capacity has extended the time from sample collection to results. These delays have led to further delays in the transfer and treatment to Ebola Treatment Units. A sensitive and specific point-of-care device that could be used reliably in low resource settings by healthcare workers with minimal training would increase the efficiency of triage and appropriate transfer of care. This article describes a study designed to validate the sensitivity and specificity of the ReEBOVTM RDT using venous whole blood and capillary blood obtained via fingerprick. We present the scientific and clinical rationale for the decisions made in the design of a diagnostic validation study to be conducted in an outbreak setting. The multi-site strategy greatly complicated implementation. In addition, a decrease in cases in one geographic area along with a concomitant increase in other areas made site selection challenging. Initiation of clinical trials during rapidly evolving outbreaks requires significant cooperation on a national level between research teams implementing studies and clinical care providers. Coordination and streamlining of approval process is essential if trials are to be implemented in a timely fashion. PMID:26768566

Both anemia and sickle cell disease (SCD) are highly prevalent across sub-Saharan Africa, and limited resources exist to diagnose these conditions quickly and accurately. The development of simple, inexpensive, and accurate point-of-care (POC) assays represents an important advance for global hematology, one that could facilitate timely and life-saving medical interventions. In this prospective study, Robust Assays for Point-of-care Identification of Disease (RAPID), we simultaneously evaluated a POC immunoassay (Sickle SCAN™) to diagnose SCD and a first-generation POC color-based assay to detect anemia. Performed at Bugando Medical Center in Mwanza, Tanzania, RAPID tested 752 participants (age 1 day to 20 years) in four busy clinical locations. With minimally trained medical staff, the SCD POC assay diagnosed SCD with 98.1% sensitivity and 91.1% specificity. The hemoglobin POC assay had 83.2% sensitivity and 74.5% specificity for detection of severe anemia (Hb ≤ 7 g/dL). Interobserver agreement was excellent for both POC assays (r = 0.95-0.96). Results for the hemoglobin POC assay have informed the second-generation assay design to be more suitable for low-resource settings. RAPID provides practical feasibility data regarding two novel POC assays for the diagnosis of anemia and SCD in real-world field evaluations and documents the utility and potential impact of these POC assays for sub-Saharan Africa.

Increasing "patient engagement" has become a priority for health care organizations and policy-makers seeking to reduce cost and improve the quality of care. While concepts of patient engagement have proliferated rapidly across health care settings, little is known about how health care providers make use of these concepts in clinical practice. This paper uses 20 months of ethnographic and interview research carried out from 2015 to 2016 to explore how health care providers working at two public, urban, safety-net hospitals in the United States define, discuss, and assess patient engagement. We investigate how health care providers describe engagement for high cost patients-the "super-utilizers" of the health care system-who often face complex challenges related to socioeconomic marginalization including poverty, housing insecurity, exposure to violence and trauma, cognitive and mental health issues, and substance use. The health care providers in our study faced institutional pressure to assess patient engagement and to direct care towards engaged patients. However, providers considered such assessments to be highly challenging and oftentimes inaccurate, particularly because they understood low patient engagement to be the result of difficult socioeconomic conditions. Providers tried to navigate the demand to assess patient engagement in care by looking for explicit positive and negative indicators of engagement, while also being sensitive to more subtle and intuitive signs of engagement for marginalized patients.

Families of patients with dementia may need support in difficult end-of-life decision making. Such guidance may be culturally sensitive. To support families in Canada, a booklet was developed to aid decision making on palliative care issues. For reasons of cost effectiveness and promising effects, we prepared for its implementation in Italy, the Netherlands and Japan. Local teams translated and adapted the booklet to local ethical, legal and medical standards where needed, retaining guidance on palliative care. Using qualitative content analyses, we grouped and compared adaptations to understand culturally sensitive aspects. Three themes emerged: (1) relationships among patient, physician and other professionals-the authority of the physician was more explicit in adapted versions; (2) patient rights and family position-adding detail about local regulations; and (3) typology of treatments and decisions. Considerations underlying palliative care decisions were detailed (Dutch and Italian versions), and the Japanese version frequently referred to professional and legal standards, and life-prolongation was a competing goal. Text on artificial feeding or fluids and euthanasia was revised extensively. Providing artificial feeding and fluids and discussing euthanasia may be particularly sensitive topics, and guidance on these subjects needs careful consideration of ethical aspects and possible adaptations to local standards and practice. The findings may promote cross-national debate on sensitive, core issues regarding end-of-life care in dementia.

The empirical and theoretical consideration of ethical decision making has focused on the process of moral judgment; however, a precondition to judgment is moral sensitivity, the ability to detect and evaluate moral issues [Rest, J. R. (1984). The major components of morality. In W. Kurtines & J. Gewirtz (Eds.), Morality, moral behaviour, and moral development (pp. 24-38). New York, NY: Wiley]. Using functional magnetic resonance imaging (fMRI) and contextually standardized, real life moral issues, we demonstrate that sensitivity to moral issues is associated with activation of the polar medial prefrontal cortex, dorsal posterior cingulate cortex, and posterior superior temporal sulcus (STS). These activations suggest that moral sensitivity is related to access to knowledge unique to one's self, supported by autobiographical memory retrieval and social perspective taking. We also assessed whether sensitivity to rule-based or "justice" moral issues versus social situational or "care" moral issues is associated with dissociable neural processing events. Sensitivity to justice issues was associated with greater activation of the left intraparietal sulcus, whereas sensitivity to care issues was associated with greater activation of the ventral posterior cingulate cortex, ventromedial and dorsolateral prefrontal cortex, and thalamus. These results suggest a role for access to self histories and identities and social perspectives in sensitivity to moral issues, provide neural representations of the subcomponent process of moral sensitivity originally proposed by Rest, and support differing neural information processing for the interpretive recognition of justice and care moral issues.

This study investigates the importance of medical fee and distance to health care provider on individual's decision to seek care in developing countries. The estimation method used a mixed logit model applied to data from the third wave of the Indonesian family life survey (2000). The key variables of interest include medical fee and distance to different types of health care provider and individual characteristic variables. Urban dweller's decision to choose health care providers are sensitive to the monetary cost of medical care as measured by medical fee but they are not sensitive to distance. For those who reside in rural area, they are sensitive to the non-medical component cost of care as measured by travel distance but they are not sensitive to medical fee. As a result of those findings, policy makers should consider different sets of policy instruments when attempting to expand health service's usage in urban and rural areas of Indonesia. To increase access in urban areas, we recommend expansion of health insurance coverage in order to lower out-of-pocket medical expenditures. As for rural areas, expansion of medical infrastructures to reduce commuting distance and costs will be needed to increase utilization. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Gluten-Related Disorders: Celiac Disease, Gluten Allergy, Non-Celiac Gluten Sensitivity.

Allen, Patricia Jackson

2015-01-01

Gluten is a protein complex found in the endosperm portion of wheat, rye, and barley. "Gluten-related disorder" is a term used to describe conditions related to ingestion of gluten-containing foods. Gluten has been implicated as the cause of a variety of gastrointestinal (GI) and extraintestinal symptoms. These symptoms are often non-specific and variable, making it difficult for the primary care provider to diagnose the cause and develop a management plan. Recently, gluten-related disorders have received much attention in the popular press, and the sale of gluten-free foods has become a multi-billion dollar business. It is important for pediatric primary care providers to understand the potential role of gluten in GI health and symptomatology so appropriate screening, diagnostic testing, and management can be provided.

The goal of this study was to appreciate principal affections and mortality and in gastroenterology service of Gabriel Touré Hospital. It is about a survey longitudinal that has permit to analyze patients who have been care. During study, 766 patients were unregistered. Mean age of patient was 45.17 years and a sex ratio (M/F) = 1.10. The rate of reference was 13.85%. The morbidity was dominated by HIV infection (29.90%) followed by Hepato-cellular Carcinoma (7.83%) and cirrhosis (4.05%). Mortality (18.41%) was dominated by the VIH infection, HCC and Cirrhosis. The precocious recourse to cares, the improvement of work conditions, the sensitization, the infectious illness prevention is factors that will permit a reduction of morbidity and hospital mortality.

Alternative health care consultations in Ontario, Canada: A geographic and socio-demographic analysis

PubMed Central

2011-01-01

Background An important but understudied component of Canada's health system is alternative care. The objective of this paper is to examine the geographic and socio-demographic characteristics of alternative care consultation in Ontario, Canada's largest province. Methods Data is drawn from the Canadian Community Health Survey (CCHS Cycle 3.1, 2005) for people aged 18 or over (n = 32,598) who had a consultation with an alternative health care provider. Four groups of consultations are examined: (1) all consultations (2) massage therapy (3) acupuncture, and (4) homeopath/naturopath. Descriptive statistics, mapping and logistic regression modeling are employed to analyze the data and to compare modalities of alternative health care use. Results In 2005, more than 1.2 million adults aged 18 or over consulted an alternative health care provider, representing about 13% of the total population of Ontario. The analysis revealed a varied geographic pattern of consultations across the province. Consultations were fairly even across the urban to rural continuum and rural residents were just as likely to consult a provider as their urban counterparts. From a health perspective, people with a chronic condition, lower health status and self-perceived unmet health care needs were more likely to see an alternative health provider. Women with chronic conditions such as fibromyalgia, high blood pressure, chronic fatigue syndrome and chemical sensitivities were more likely to see an alternative provider if they felt their health care needs were not being met. Conclusions The analysis revealed that geography is not a factor in determining alternative health care consultations in Ontario. By contrast, there is a strong association between these consultations and socio-demographic characteristics particularly age, sex, education, health and self-perceived unmet health care needs. The results underscore the importance of women's health needs as related to alternative care use. The paper concludes that there is a need for more place-specific research that explores the reasons why people use specific types of alternative health care as tied to socio-economic status, health, place of residence, and knowledge of these treatments.

Planning ahead with children with life-limiting conditions and their families: development, implementation and evaluation of ‘My Choices’

PubMed Central

2013-01-01

Background The United Kingdom has led the world in the development of children’s palliative care. Over the past two decades, the illness trajectories of children with life-limiting conditions have extended with new treatments and better home-based care. Future planning is a critically under-researched aspect of children’s palliative care globally. This paper describes the development, implementation and evaluation of innovative child and parent-held palliative care planning resources. The resources were designed to facilitate parent and child thinking and engagement in future planning, and to determine care preferences and preferred locations of care for children with life-limiting conditions from diagnosis onwards. These resources fill a significant gap in palliative care planning before the end-of-life phase. Methods Drawing on contemporaneous research on producing evidence-based children’s health information, we collaborated with leading children’s not-for-profit organisations, parents, children, and professionals. A set of resources (My Choices booklets) were developed for parents and children and evaluated using interviews (parents, children, professionals) and questionnaires (professionals) and an open web-based consultation. Results Parents and children responded in three ways: Some used the booklets to produce detailed written plans with clear outcomes and ideas about how best to achieve desired outcomes. Others preferred to use the booklet to help them think about potential options. Remaining parents found it difficult to think about the future and felt there was no point because they perceived there to be no suitable local services. Professionals varied in confidence in their ability to engage with families to plan ahead and identified many challenges that prevented them from doing so. Few families shared their plans with professionals. Parents and children have far stronger preferences for home-care than professionals. Conclusion The My Choices booklets were revised in light of findings, have been endorsed by Together for Short Lives, and are free to download in English and Welsh for use by parents and young people globally. More work needs to be done to support families who are not yet receptive to planning ahead. Professionals would benefit from more training in person-centred approaches to future planning and additional communications skills to increase confidence and ability to engage with families to deliver sensitive palliative care planning.

A patchwork of services is available to the US uninsured through the healthcare safety net (SN). During 1996–2003, some SN hospitals (SNHs) closed or converted ownership from public or non-profit to for-profit status. However, around this time the number of community health centers (CHCs) grew due to new federal funding. This paper examines the impact of these two countervailing SN events on access to care for the uninsured. Hospital admissions for ambulatory care sensitive conditions (ACSCs) relative to marker conditions were used as our access measure. We examined 35,730 discharges for uninsured adults treated in Florida hospitals in the years 1992 or 2003. A generalized estimating equation model was used to assess differential access effects for racial and ethnic groups. We found that in communities with CHC openings but no SNH contractions, uninsured black and white individuals experienced deteriorations in access over time but the Hispanic uninsured did not. However, in communities where SNHs closed or converted, access deteriorations occurred for all three racial and ethnic groups. Thus, the potentially beneficial effects of CHC expansions on access to primary care for the uninsured Hispanic population in Florida appeared to be offset if contractions in the hospital safety net were present.

Neurosurgery and Telemedicine in the United States: Assessment of the Risks and Opportunities.

PubMed

Kahn, Elyne N; La Marca, Frank; Mazzola, Catherine A

2016-05-01

Telemedicine has seen substantial growth in the past 20 years, related to technologic advancements and evolving reimbursement policies. The risks and opportunities of neurosurgical telemedicine are nuanced. We reviewed general and peer-reviewed literature as it relates to telemedicine and neurosurgery, with particular attention to best practices, relevant state and federal policy conditions, economic evaluations, and prospective clinical studies. Despite technologic development, growing interest, and increasing reimbursement opportunities, telemedicine's utilization remains limited because of concerns regarding an apparent lack of need for telemedicine services, lack of widespread reimbursement, lack of interstate licensure reciprocity, lack of universal access to necessary technology, concerns about maintaining patient confidentiality, and concerns and limited precedent regarding liability issues. The Veterans Health Administration, a component of the U.S. Department of Veterans Affairs, represents a setting in which these concerns can be largely obviated and is a model for telemedicine best practices. Results from the VA demonstrate substantial cost savings and patient satisfaction with remote care for chronic neurologic conditions. Overall, the economic and clinical benefits of telemedicine will likely come from 1) diminished travel times and lost work time for patients; 2) remote consultation of subspecialty experts, such as neurosurgeons; and 3) remote consultation to assist with triage and care in time-sensitive scenarios, including acute stroke care and "teletrauma." Telemedicine is effective in many health care scenarios and will become more relevant to neurosurgical patient care. We favor proceeding with legislation to reduce barriers to telemedicine's growth.

Technological advances and societal changes in recent years have contributed to a shift in traditional care models and in the relationship between patients and their doctors/carers, with (in general) an increase in the patient-carer physical distance and corresponding changes in the modes of access to relevant care information by all groups. The objective of this paper is to showcase the research efforts of six projects (that the authors are currently, or have recently been, involved in), CAALYX, eCAALYX, COGKNOW, EasyLine+, I2HOME, and SHARE-it, all funded by the European Commission towards a future where citizens can take an active role into managing their own healthcare. Most importantly, sensitive groups of citizens, such as the elderly, chronically ill and those suffering from various physical and cognitive disabilities, will be able to maintain vital and feature-rich connections with their families, friends and healthcare providers, who can then respond to, and prevent, the development of adverse health conditions in those they care for in a timely manner, wherever the carers and the people cared for happen to be.

dosReis, Susan; Castillo, Wendy Camelo; Ross, Melissa; Fitz-Randolph, Marcy; Vaughn-Lee, Angela; Butler, Beverly

To develop a methodological approach for selecting, validating, and prioritizing attributes for health care decision making. Participants (n = 48) were recruited from community support groups if they had a child aged 26 years or younger diagnosed with a coexisting mental health condition and cognitive impairment. Six in-depth interviews eliciting care management experiences were transcribed and coded into themes following the principles of grounded theory and the constant comparative method. Six focus groups involving 42 participants assessed the relevance, priority, and meaning and inter-relationship among the themes. The positive predictive value and sensitivity assessed agreement on thematic meaning. A final list was selected from the top priorities with good agreement as candidate attributes. Attribute levels reflecting the range of experiences in care management decisions emerged from the verbatim passages within each coded theme. Participants were the child's mother (73%), white (77%), married (69%), and on average 48 years old. The children were on average 14 years old; 44% had an intellectual disability, 25% had autism, and more than half had anxiety or attention-deficit/hyperactivity disorder. All 14 attributes identified from the in-depth interviews were deemed relevant. The positive predictive value exceeded 90%, and the sensitivity ranged from 64% to 89%. The final set of attributes formed the framework for care management decisions consisting of six attributes (medication, behavior, services, social, treatment effects, and school) each with three levels. A systematic approach grounded in qualitative methods produced a framework of relevant, important, and actionable attributes representing competing alternatives in clinical decisions.

We evaluate the sensitivity of Ohio's 2009 emergency medical services (EMS) geriatric trauma triage criteria compared with the previous adult triage criteria in identifying need for trauma center care among older adults. We studied a retrospective cohort of injured patients aged 16 years or older in the 2006 to 2011 Ohio Trauma Registry. Patients aged 70 years or older were considered geriatric. We identified whether each patient met the geriatric and the adult triage criteria. The outcome measure was need for trauma center care, defined by surrogate markers: Injury Severity Score greater than 15, operating room in fewer than 48 hours, any ICU stay, and inhospital mortality. We calculated sensitivity and specificity of both triage criteria for both age groups. We included 101,577 patients; 33,379 (33%) were geriatric. Overall, 57% of patients met adult criteria and 68% met geriatric criteria. Using Injury Severity Score, for older adults geriatric criteria were more sensitive for need for trauma center care (93%; 95% confidence interval [CI] 92% to 93%) than adult criteria (61%; 95% CI 60% to 62%). Geriatric criteria decreased specificity in older adults from 61% (95% CI 61% to 62%) to 49% (95% CI 48% to 49%). Geriatric criteria in older adults (93% sensitivity, 49% specificity) performed similarly to the adult criteria in younger adults (sensitivity 87% and specificity 44%). Similar patterns were observed for other outcomes. Standard adult EMS triage guidelines provide poor sensitivity in older adults. Ohio's geriatric trauma triage guidelines significantly improve sensitivity in identifying Injury Severity Score and other surrogate markers of the need for trauma center care, with modest decreases in specificity for older adults.

How do high cost-sharing policies for physician care affect inpatient care use and costs among people with chronic disease?

PubMed

Xin, Haichang

2015-01-01

Rapidly rising health care costs continue to be a significant concern in the United States. High cost-sharing strategies thus have been widely used to address rising health care costs. Since high cost-sharing policies can reduce needed care as well as unneeded care use, it raises the concern whether these policies for physician care are a good strategy for controlling costs among chronically ill patients, especially whether utilization and costs in inpatient care will increase in response. This study examined whether high cost sharing in physician care affects inpatient care utilization and costs differently between individuals with and without chronic conditions. Findings from this study will contribute to the insurance benefit design that can control care utilization and save costs of chronically ill individuals. Prior studies suffered from gaps that limit both internal validity and external validity of their findings. This study has its unique contributions by filling these gaps jointly. The study used data from the 2007 Medical Expenditure Panel Survey, a nationally representative sample, with a cross-sectional study design. Instrumental variable technique was used to address the endogeneity between health care utilization and cost-sharing levels. We used negative binomial regression to analyze the count data and generalized linear models for costs data. To account for national survey sampling design, weight and variance were adjusted. The study compared the effects of high cost-sharing policies on inpatient care utilization and costs between individuals with and without chronic conditions to answer the research question. The final study sample consisted of 4523 individuals; among them, 752 had hospitalizations. The multivariate analysis demonstrated consistent patterns. Compared with low cost-sharing policies, high cost-sharing policies for physician care were not associated with a greater increase in inpatient care utilization (P = .86 for chronically ill people and P = .67 for healthy people, respectively) and costs (P = .38 for chronically ill people and P = .68 for healthy people, respectively). The sensitivity analysis with a 10% cost-sharing level also generated consistent insignificant results for both chronically ill and healthy groups. Relative to nonchronically ill individuals, chronically ill individuals may increase their utilization and expenditures of inpatient care to a similar extent in response to increased physician care cost sharing. This may be due to cost pressure from inpatient care and short observation window. Although this study did not find evidence that high cost-sharing policies for physician care increase inpatient care differently for individuals with and without chronic conditions, interpretation of this finding should be cautious. It is possible that in the long run, these sick people would demonstrate substantial demands for medical care and there could be a total cost increase for health plans ultimately. Health plans need to be cautious of policies for chronically ill enrollees.

Specialized outpatient psychotherapy for patients with borderline personality disorder (BPD) is expected to reduce their use of other health care resources. It is currently unknown to what extent the costs of providing these interventions can be expected to be offset by a reduction in other health care costs in the Netherlands. To establish the cost-effectiveness and budget impact of specialized outpatient psychotherapy, the estimated incremental costs are synthesized with the estimated incremental effects. We have developed a method for the synthesis of all relevant evidence on clinical effectiveness as well as health care resource use. The aim of this article is to present a method for the synthesis of evidence for cost-effectiveness and budget impact analysis with a specific application to specialized outpatient psychotherapy for borderline personality disorder in the Netherlands. A systematic search of the English-language literature is performed to retrieve evidence on the clinical effectiveness and the health care resource use following 12 months of specialized outpatient psychotherapy for borderline personality disorder. The available evidence is used as an input for a model-based economic evaluation. Simulated patient-level data are used to provide overall estimates of the incremental costs and incremental effects, which serve to assess the cost-effectiveness and budget impact of specialized outpatient psychotherapy for borderline personality disorder in the Netherlands. The results indicate that specialized outpatient psychotherapy for BPD can be considered cost-effective and that its scaling up to Dutch national level would require an investment of 2.367 million (95% C.I.: 1,717,000 - 3,272,000) per 1,000 additional patients with BPD. Sensitivity analyses demonstrated the robustness of our findings in light of several uncertain components and assumptions in our calculations, but also their sensitivity to the choice of included studies based on the comparator condition and the assumption of high intervention costs. We present a method for the synthesis of evidence from different types of studies in a way that respects the uncertainty surrounding those findings. Limitations of the study pertain to the inclusion of findings from studies with suboptimal designs, the transferability of research findings, and uncertainty regarding the time horizon considered. More research is needed on the sensitivity of our findings to the choice of included studies based on the comparator condition. THE results suggest that the provision of specialized outpatient psychotherapy for BPD leads to a reduction in other health care resource use. Overall, the results are promising and encourage future studies on aspects that are currently still uncertain. The results may support policy makers in deciding whether or not to allocate health care budget for the provision of specialized outpatient psychotherapy for patients with BPD in the Netherlands. The results provide important directions for future research. This includes the need for future studies to make a comparison between specialized outpatient psychotherapy and treatment as usual and to have longer follow-up time.

Through interviews, we examined explanatory frameworks of living with HIV infection among 50 HIV-positive individuals (23 women, 27 men) receiving care at a non-governmental organization in Chennai, India. Results were analysed according to three sets of issues, all of which were found to differ by gender: causal beliefs about HIV, impact of HIV, and care/treatment of HIV. HIV-positive participants attributed their infection to biological, moral and social causes, and the physical, financial and relationship dimensions of their lives were impacted upon by the infection. Furthermore, HIV-related stigma evoked fears about isolation and discrimination. Regarding care/treatment, men were most usually first initiated into the healthcare system while women often entered as a consequence of their partner's condition. Non-adherence to medication was reported by 32% of the participants due to financial constraints or side-effects. Although all participants were hopeful about a cure for HIV, women were less positive than men about treatment. Results highlight the importance of a gender-sensitive approach to HIV care, nuanced to accommodate an individual's gender, marital status and social background.

To assess whether black-white and Hispanic-white disparities increase or abate in the upper quantiles of total health care expenditure, conditional on covariates. Nationally representative adult population of non-Hispanic whites, African Americans, and Hispanics from the 2001-2005 Medical Expenditure Panel Surveys. We examine unadjusted racial/ethnic differences across the distribution of expenditures. We apply quantile regression to measure disparities at the median, 75th, 90th, and 95th quantiles, testing for differences over the distribution of health care expenditures and across income and education categories. We test the sensitivity of the results to comparisons based only on health status and estimate a two-part model to ensure that results are not driven by an extremely skewed distribution of expenditures with a large zero mass. Black-white and Hispanic-white disparities diminish in the upper quantiles of expenditure, but expenditures for blacks and Hispanics remain significantly lower than for whites throughout the distribution. For most education and income categories, disparities exist at the median and decline, but remain significant even with increased education and income. Blacks and Hispanics receive significantly disparate care at high expenditure levels, suggesting prioritization of improved access to quality care among minorities with critical health issues.

The effects of reward and punishment are different, and there are individual differences in sensitivity to reward and punishment. The purpose of this study was to investigate the effects of reward and punishment on task performance, mood, and autonomic nervous function, along with the interaction with personality. Twenty-one healthy female subjects volunteered for the experiment. The task performance was evaluated by required time and total errors while performing a Wisconsin Card Sorting Test. We assessed their personalities using the Minnesota Multiphasic Personality Inventory (MMPI) questionnaire, and mood states by a profile of mood states. Autonomic nervous function was estimated by a spectral analysis of heart rate variability, baroreflex sensitivity, and blood pressure. Repeated measures analysis of variance (ANOVA) revealed significant interaction of condition x time course on mood and autonomic nervous activity, which would indicate a less stressed state under the rewarding condition, but revealed no significant interaction of condition x time course on the task performance. The interactions with personality were further analyzed by repeated measures ANOVA applying the clinical scales of MMPI as independent variables, and significant interactions of condition x time course x Pt (psychasthenia) on task performance, mood, and blood pressure, were revealed. That is, the high Pt group, whose members tend to be sensitive and prone to worry, showed gradual improvement of task performance under the punishing situation with slight increase in systolic blood pressure, while showed no improvement under the rewarding situation with fatigue sense attenuation. In contrast, the low Pt group, whose members tend to be adaptive and self-confident, showed gradual improvement under the rewarding situation. Therefore, we should carefully choose the strategy of reward or punishment, considering the interaction with personality as well as the context in which it is given.

We report an aptamer-nanoparticle strip biosensor (ANSB) for the rapid, specific, sensitive and low-cost detection of circulating cancer cells. Known for their high specificity and affinity, aptamers were first selected from live cells by the cell-SELEX (systematic evolution of ligands by exponential enrichment) process. When next combined with the unique optical properties of gold nanoparticles (Au-NPs), ANSBs were prepared on a lateral flow device. Ramos cells were used as a model target cell to demonstrate proof of principle. Under optimal conditions, the ANSB was capable of detecting a minimum of 4000 Ramos cells without instrumentation (visual judgment) and 800 Ramos cells with a portable strip reader within 15 minutes. Importantly, ANSB has successfully detected Ramos cells in human blood, thus providing a rapid, sensitive and low-cost quantitative tool for the detection of circulating cancer cells. ANSB therefore shows great promise for in-field and point-of-care cancer diagnosis and therapy. PMID:19904989

To compare the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) and the Intensive Care Delirium Screening Checklist (ICDSC) for detecting post-cardiac surgery delirium. These tools have not been tested in a specialized cardio-surgical ICU. Sensitivities and specificities of each tool were assessed in a cardio-surgical ICU in Japan by two trained nurses independently. Results were compared with delirium diagnosed by psychiatrists using the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision. There were 110 daily, paired assessments in 31 patients. The CAM-ICU showed 38% sensitivity and 100% specificity for both nurses. All 20 false-negative cases resulted from high scores in the auditory attention screening in CAM-ICU. The ICDSC showed 97% and 94% sensitivity, and 97% and 91% specificity for the two nurses (cutoff ≥4). In a Japanese cardio-surgical ICU, the ICDSC had a higher sensitivity than the CAM-ICU.

2015-05-08

Facioscapulohumeral muscular dystrophy (FSHD) is believed to be caused by aberrant expression of double homeobox 4 (DUX4) due to epigenetic changes of the D4Z4 region at chromosome 4q35. Detecting DUX4 is challenging due to its stochastic expression pattern and low transcription level. In this study, we examined different cDNA synthesis strategies and the sensitivity for DUX4 detection. In addition, we investigated the effects of dexamethasone and knockout serum replacement (KOSR) on DUX4 expression in culture. Our data showed that DUX4 was consistently detected in cDNA samples synthesized using Superscript III. The sensitivity of DUX4 detection was higher in the samples synthesized using oligo(dT) primers compared to random hexamers. Adding dexamethasone to the culture media significantly suppressed DUX4 expression in immortalized (1.3 fold, p < 0.01) and primary (4.7 fold, p < 0.01) FSHD myoblasts, respectively. Culture medium with KOSR increased DUX4 expression and the response is concentration dependent. The findings suggest that detection strategies and culture conditions should be carefully considered when studying DUX4 in cultured cells.

Because of worldwide migration, the healthcare staff in general as well as in paedi"atric care specifically is challenged increasingly by people from various ethnic backgrounds. The challenge is related to providing culturally competent care and effectively communicating with people from diverse cultural and ethnic backgrounds who have different health beliefs, practices, values and languages. This also applies to the Swedish society and to Swedish paediatric care. The purpose of this study was to describe the expectations and experiences of cross-cultural care encounters among minority ethnic parents in Swedish paediatric care. A qualitative design was used in the study. Data were collected using semi-structured interviews between October 2011 and March 2012. The sample consisted of 12 parents of minority ethnic backgrounds who had their child in a ward at a children's hospital in the Stockholm County Council. The interviews were analysed using manifest content analysis. The Regional Ethical Review Committee approved the study (Ref: Nr: 2011/927-31/5). The analysis of the interviews led to three categories: fundamentals in nursing, cultural sensitivity and understanding, and influencing conditions. Generic knowledge and skills of nurses outweighed the need for the nurses to have culture-specific knowledge of their patients or relatives in cross-cultural care encounters. Language skills and the availability of bilingual nurses in a multi-ethnic society can facilitate communication and increase parents' satisfaction in cross-cultural care encounters. © 2016 Nordic College of Caring Science.

This review, commissioned by the Research Councils UK Living With Environmental Change (LWEC) programme, concerns research on the impacts on health and social care systems in the United Kingdom of extreme weather events, under conditions of climate change. Extreme weather events considered include heatwaves, coldwaves and flooding. Using a structured review method, we consider evidence regarding the currently observed and anticipated future impacts of extreme weather on health and social care systems and the potential of preparedness and adaptation measures that may enhance resilience. We highlight a number of general conclusions which are likely to be of international relevance, although the review focussed on the situation in the UK. Extreme weather events impact the operation of health services through the effects on built, social and institutional infrastructures which support health and health care, and also because of changes in service demand as extreme weather impacts on human health. Strategic planning for extreme weather and impacts on the care system should be sensitive to within country variations. Adaptation will require changes to built infrastructure systems (including transport and utilities as well as individual care facilities) and also to institutional and social infrastructure supporting the health care system. Care sector organisations, communities and individuals need to adapt their practices to improve resilience of health and health care to extreme weather. Preparedness and emergency response strategies call for action extending beyond the emergency response services, to include health and social care providers more generally.

To explore the methodological and ethical issues of conducting qualitative telephone interviews about personal or professional trauma with critical care nurses. The most common method for conducting interviews is face-to-face. However, there is evidence to support telephone interviewing on a variety of sensitive topics including post-traumatic stress disorder (PTSD). Qualitative telephone interviews can limit emotional distress because of the comfort experienced through virtual communication. Critical care nurses are at increased risk of developing PTSD due to the cumulative exposure to work-related stress in the intensive care unit. We explored the methodological and ethical issues of conducting qualitative telephone interviews, drawing on our experiences communicating with a group of critical care nurses. Qualitative research interviews with 27 critical care nurses. Fourteen of the nurses met the diagnostic criteria for PTSD; 13 did not and had scores consistent with high levels of resilience. This is a methodology paper on the authors' experiences of interviewing critical care nurses on sensitive topics via the telephone. The authors found that establishing rapport and connections with the participants and the therapeutic use of non-verbal communication were essential, and fostered trust and compassion. The ethical issues of this mode of communication include protecting the privacy and confidentiality associated with the disclosure of sensitive information, and minimising the risk of psychological harm to the researcher and participants. Qualitative telephone interviews are a valuable method of collecting information on sensitive topics. This paper explores a method of interviewing in the workplace. It will help inform interventions to promote healthy adaptation following trauma exposure in the intensive care unit.

Does Assessing Eye Alignment along with Refractive Error or Visual Acuity Increase Sensitivity for Detection of Strabismus in Preschool Vision Screening?

PubMed Central

2007-01-01

Purpose Preschool vision screenings often include refractive error or visual acuity (VA) testing to detect amblyopia, as well as alignment testing to detect strabismus. The purpose of this study was to determine the effect of combining screening for eye alignment with screening for refractive error or reduced VA on sensitivity for detection of strabismus, with specificity set at 90% and 94%. Methods Over 3 years, 4040 preschool children were screened in the Vision in Preschoolers (VIP) Study, with different screening tests administered each year. Examinations were performed to identify children with strabismus. The best screening tests for detecting children with any targeted condition were noncycloplegic retinoscopy (NCR), Retinomax autorefractor (Right Manufacturing, Virginia Beach, VA), SureSight Vision Screener (Welch-Allyn, Inc., Skaneateles, NY), and Lea Symbols (Precision Vision, LaSalle, IL and Good-Lite Co., Elgin, IL) and HOTV optotypes VA tests. Analyses were conducted with these tests of refractive error or VA paired with the best tests for detecting strabismus (unilateral cover testing, Random Dot “E” [RDE] and Stereo Smile Test II [Stereo Optical, Inc., Chicago, IL]; and MTI PhotoScreener [PhotoScreener, Inc., Palm Beach, FL]). The change in sensitivity that resulted from combining a test of eye alignment with a test of refractive error or VA was determined with specificity set at 90% and 94%. Results Among the 4040 children, 157 were identified as having strabismus. For screening tests conducted by eye care professionals, the addition of a unilateral cover test to a test of refraction generally resulted in a statistically significant increase (range, 15%–25%) in detection of strabismus. For screening tests administered by trained lay screeners, the addition of Stereo Smile II to SureSight resulted in a statistically significant increase (21%) in sensitivity for detection of strabismus. Conclusions The most efficient and low-cost ways to achieve a statistically significant increase in sensitivity for detection of strabismus were by combining the unilateral cover test with the autorefractor (Retinomax) administered by eye care professionals and by combining Stereo Smile II with SureSight administered by trained lay screeners. The decision of whether to include a test of alignment should be based on the screening program’s goals (e.g., targeted visual conditions) and resources. PMID:17591881

Background and objectives Awareness of CKD is necessary for patient engagement and adherence to medical regimens. Having an accurate tool to assess awareness is important. Use of the National Health and Nutrition Examination Survey (NHANES) CKD awareness question “Have you ever been told by a doctor or other health professional that you had weak or failing kidneys (excluding kidney stones, bladder infections, or incontinence)?” produces surprisingly low measures of CKD awareness. We sought to compare the sensitivity and specificity of different questions ascertaining awareness of CKD and other health conditions. Design, setting, participants, & measurements Between August of 2011 and August of 2014, an in-person questionnaire was administered to 220 adults with CKD, diabetes, hypertension, or hyperlipidemia who received primary care in a public health care delivery system to ascertain awareness of each condition. CKD awareness was measured using the NHANES question, and other questions, asking if patients knew about their “kidney disease”, “protein in the urine”, “kidney problem”, or “kidney damage.” Demographic data were self-reported; health literacy was measured. The sensitivity and specificity of each question was calculated using the medical record as the gold standard. Results In this diverse population (9.6% white, 40.6% black, 36.5% Hispanic, 12.3% Asian), the mean age was 58 years, 30% had a non-English language preference, and 45% had low health literacy. Eighty percent of participants had CKD, with a mean eGFR of 47.2 ml/min per 1.73 m2. The sensitivities of each CKD awareness question were: 26.4% for “kidney damage”, 27.7% for “kidney disease”, 33.2% for “weak or failing kidneys”, 39.8% for “protein in the urine”, and 40.1% for “kidney problem.” Specificities ranged from 82.2% to 97.6%. The best two-question combination yielded a sensitivity of 53.1% and a specificity of 83.3%. This was lower than awareness of hypertension (90.1%) or diabetes (91.8%). Conclusions CKD awareness is low compared with other chronic diseases regardless of how it is ascertained. Nevertheless, more sensitive questions to ascertain CKD awareness suggest current under-ascertainment. PMID:27340288

Objective To assess the validity of standardised patients to measure the quality of physicians' practice. Design Validation study of standardised patients' assessments. Physicians saw unannounced standardised patients presenting with common outpatient conditions. The standardised patients covertly tape recorded their visit and completed a checklist of quality criteria immediately afterwards. Their assessments were compared against independent assessments of the recordings by a trained medical records abstractor. Setting Four general internal medicine primary care clinics in California. Participants 144 randomly selected consenting physicians. Main outcome measures Rates of agreement between the patients' assessments and independent assessment. Results 40 visits, one per standardised patient, were recorded. The overall rate of agreement between the standardised patients' checklists and the independent assessment of the audio transcripts was 91% (κ=0.81). Disaggregating the data by medical condition, site, level of physicians' training, and domain (stage of the consultation) gave similar rates of agreement. Sensitivity of the standardised patients' assessments was 95%, and specificity was 85%. The area under the receiver operator characteristic curve was 90%. Conclusions Standardised patients' assessments seem to be a valid measure of the quality of physicians' care for a variety of common medical conditions in actual outpatient settings. Properly trained standardised patients compare well with independent assessment of recordings of the consultations and may justify their use as a “gold standard” in comparing the quality of care across sites or evaluating data obtained from other sources, such as medical records and clinical vignettes. What is already known on this topicStandardised patients are valid and reliable reporters of physicians' practice in the medical education settingHowever, validating standardised patients' measurements of quality of care in actual primary practice is more difficult and has not been done in a prospective studyWhat this study addsReports of physicians' quality of care by unannounced standardised patients compare well with independent assessment of the consultations PMID:12351358

The conditions of children and adolescents with migration background receiving emergency psychiatric care in Europe are not well known. Migrants usually attend regular psychiatric care less frequently than the autochthonous population. We therefore speculated that, being undertreated, they would be overrepresented among psychiatric emergency care patients. We retrospectively analyzed the records of 1093 minors aged 4‑18 years treated during a period of three years at the psychiatric emergency outpatient clinic of the Department of Child and Adolescent Psychiatry at the Medical University of Vienna. More minors with migration background than natives consulted our emergency clinic. Most frequent reasons for referral were suicide attempts by Turkish patients, acute stress disorder in Serbian/Croatian/Bosnian and in Austrian patients. Psychiatric diagnoses like eating and personality disorders were mostly diagnosed in natives. We found gender specific differences between the groups. The reasons for these differences possibly relate to deficits of adequate mental health-care in Austria, to intercultural and intrafamiliar conflicts related to acculturation distress in the migrant population. Prospective longitudinal studies focusing on the utilization of mental health care by the migrant children and the impact of the migration background on their mental health are needed for improving adequate culture-sensitive mental-health care for this population.

Obesity has become a major public health issue and there is concern about the response of health services to patients who are obese. The perceptions of obese patients using primary care services have not been studied in depth. To explore obese patients' experiences and perceptions of support in primary care. Qualitative study with semi-structured interviews conducted in participants' homes. Five general practices contrasting in socioeconomic populations in Sheffield. Purposive sampling and semi-structured interviewing of 28 patients with a diverse range of ages, backgrounds, levels of obesity and experiences of primary care services. Participants typically felt reluctance when presenting with concerns about weight and ambivalence about the services received. They also perceived there to be ambivalence and a lack of resources on the part of the health services. Participants showed a strong sense of personal responsibility about their condition and stigma-related cognitions were common. These contributed to their ambivalence about using services and their sensitivity to its features. Good relationships with primary care professionals and more intensive support partly ameliorated these effects. The challenges of improving access to and quality of primary care support in tackling obesity are made more complex by patients' ambivalence and other effects of the stigma associated with obesity.

Objective Periods of economic instability may increase preventable hospitalizations because of increased barriers to accessing primary care. For underserved populations such as the homeless, these barriers may be more pronounced due to limited resources in the health care safety net. This study examined the impact of the global financial crisis of 2007-2008 on access to care for the homeless in New York State. Methods Hospitalizations for ambulatory care sensitive conditions (ACSCs) were used as a proxy measure for primary care access. Admissions for ACSCs were identified in the New York State Inpatient Database from 2006 to 2012. Hospitalization rates for ACSCs were calculated for the homeless and nonhomeless. Multivariable linear regression was used to investigate the impact of the financial crisis on hospitalization rates for ACSCs. Results The findings indicate that during the financial crisis, homeless adults had significantly higher preventable hospitalizations than nonhomeless adults, and the uninsured homeless had significantly higher preventable hospitalizations when compared to other homeless subgroups. After the financial crisis, preventable hospitalizations for the homeless stabilized but remained at higher rates than those for the nonhomeless. Conclusions These findings are important to developing health policies designed to provide effective care for underserved population such as the homeless.

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 preventable admissions. © McCormick et al 2015.

Self-care and management of therapeutic regime (drugs adherence, preventive behaviours and development of healthy life-styles) are key components for managing chronic diseases. Nursing has standardized languages which describe many of these situations, such as the diagnosis "Ineffective Self Health Management" (ISHM) or many of the Nursing Outcomes Classification (NOC) indicators. The aims of this study were to determine the interobserver reliability of a NOC-based instrument for assessment and aid in diagnosis of the ISHM in patients with chronic conditions in Primary Health Care, to determine its diagnostic validity and to describe the prevalence of patients with this problem. Cross-sectional validation study developed in the provinces of Málaga, Cádiz and Almería from 2006 to 2009. Each patient was assessed by 3 independent observers: the first two observers evaluated scoring of the NOC indicators and the third one acted as the "gold-standard". Two hundred and twenty-eight patients were included, 37.7% of them with more than one chronic condition. NOC indicators showed a high interobserver reliability (ICC>0,70) and a consistency (Cronbach's alpha: 0.81). With a cut-point of 10.5, sensitivity was 61% and specificity 85%, and the area under the curve was 0.81 (CI95%: 0.77 to 0.85). The prevalence of patients with ISHM was 36% (CI 95%: 34 to 40). The use of NOC indicators allows evaluation of management of the therapeutic regime in people with chronic conditions with a satisfactory validity and it provides new approaches for dealing with this problem.

To measure the relative efficiency of primary care (PC) in turning their structures into services delivery and turning their services delivery into quality outcomes. Cross-sectional study based on the dataset of the Primary Healthcare Activity Monitor for Europe project. Two Data Envelopment models were run to compare the relative technical efficiency. A sensitivity analysis of the resulting efficiency scores was performed. PC systems in 22 European countries in 2009/2010. Model 1 included data on PC governance, workforce development and economic conditions as inputs and access, coordination, continuity and comprehensiveness of care as outputs. Model 2 included the previous process dimensions as inputs and quality indicators as outputs. There is relatively reasonable efficiency in all countries at delivering as many as possible PC processes at a given level of PC structure. It is particularly important to invest in economic conditions to achieve an efficient structure-process balance. Only five countries have fully efficient PC systems in turning their services delivery into high quality outcomes, using a similar combination of access, continuity and comprehensiveness, although they differ on the adoption of coordination of services. There is a large variation in efficiency levels obtained by countries with inefficient PC in turning their services delivery into quality outcomes. Maximizing the individual functions of PC without taking into account the coherence within the health-care system is not sufficient from a policymaker's point of view when aiming to achieve efficiency.

Prostate cancer (PrCA) is the most common cancer affecting men in the United States, and African American men have the highest incidence among men in the United States. Little is known about the PrCA-related educational materials being provided to patients in health-care settings. Content, readability, and cultural sensitivity of materials available in providers' practices in South Carolina were examined. A total of 44 educational materials about PrCA and associated sexual dysfunction was collected from 16 general and specialty practices. The content of the materials was coded, and cultural sensitivity was assessed using the Cultural Sensitivity Assessment Tool. Flesch Reading Ease, Flesch-Kincaid Grade Level, and the Simple Measure of Gobbledygook were used to assess readability. Communication with health-care providers (52.3%), side effects of PrCA treatment (40.9%), sexual dysfunction and its treatment (38.6%), and treatment options (34.1%) were frequently presented. All materials had acceptable cultural sensitivity scores; however, 2.3% and 15.9% of materials demonstrated unacceptable cultural sensitivity regarding format and visual messages, respectively. Readability of the materials varied. More than half of the materials were written above a high-school reading level. PrCA-related materials available in health-care practices may not meet patients' needs regarding content, cultural sensitivity, and readability. A wide range of educational materials that address various aspects of PrCA, including treatment options and side effects, should be presented in plain language and be culturally sensitive.

A decade ago celiac disease was considered extremely rare outside Europe and, therefore, was almost completely ignored by health care professionals. In only 10 years, key milestones have moved celiac disease from obscurity into the popular spotlight worldwide. Now we are observing another interesting phenomenon that is generating great confusion among health care professionals. The number of individuals embracing a gluten-free diet (GFD) appears much higher than the projected number of celiac disease patients, fueling a global market of gluten-free products approaching $2.5 billion (US) in global sales in 2010. This trend is supported by the notion that, along with celiac disease, other conditions related to the ingestion of gluten have emerged as health care concerns. This review will summarize our current knowledge about the three main forms of gluten reactions: allergic (wheat allergy), autoimmune (celiac disease, dermatitis herpetiformis and gluten ataxia) and possibly immune-mediated (gluten sensitivity), and also outline pathogenic, clinical and epidemiological differences and propose new nomenclature and classifications.

This preliminary study demonstrates SAW biosensor detection of the Ebola virus in a concentration-dependent manner. The detection limit with this methodology is below the average level of viremia detected on the first day of symptoms by PCR. We observe a log-linear sensor response for highly fragmented Ebola viral particles, with a detection limit corresponding to 1.9 × 10⁴ PFU/mL prior to virus inactivation. We predict greatly improved sensitivity for intact, infectious Ebola virus. This point-of-care methodologymore » has the potential to detect Ebola viremia prior to symptom onset, greatly enabling infection control and rapid treatment.

To analyse the prevalence of GAD and other anxiety disorders, as well as sensitivity and specificity of GAD-7 among high utilizers of health care. Four municipal health centres in Northern Finland. A psychiatric interview was conducted for 150 high utilizers of health care. Prevalence of GAD as well as sensitivity and specificity of GAD-7. The prevalence of GAD was 4% in this study group of Finnish high utilizers of health care. The sensitivity of GAD-7 was 100.0% (95% CI 54.1-100.0) and the specificity of GAD-7 was 82.6% (95% CI 75.4-88.4) with a cut-off point of 7 or more. GAD is rather common among high utilizers of primary care, although the prevalence of 4% is lower than that previously reported. GAD-7 is a valid and useful tool for detecting GAD among primary health care patients.

Modelling the Centers of Galaxies

The key to studying central regions by means of nobody numerical experiments is to concentrate on the central few parsecs of a galaxy, replacing the remainder of the galaxy by a suitable boundary condition, rather after the manner in which stellar interiors can be studied without a detailed stellar atmosphere by replacing the atmosphere with a boundary condition. Replacements must be carefully designed because the long range gravitational force means that the core region is sensitive to mass outside that region and because particles can exchange between the outer galaxy and the core region. We use periodic boundary conditions, coupled with an iterative procedure to generate initial particle loads in isothermal equilibrium. Angular momentum conservation is ensured for problems including systematic rotation by a circular reflecting boundary and by integrating in a frame that rotates with the mean flow. Mass beyond the boundary contributes to the gravitational potential, but does not participate in the dynamics. A symplectic integration scheme has been developed for rotating coordinate systems. This combination works well, leading to robust configurations. Some preliminary results with this combination show that: (1) Rotating systems are extremely sensitive to non-axisymmetric external potentials, and (2) that a second core, orbiting near the main core (like the M31 second core system), shows extremely rapid orbital decay. The experimental setups will be discussed, along with preliminary results.

The relationship between body system-based chronic conditions and dental utilization for Medicaid-enrolled children: a retrospective cohort study

PubMed Central

2012-01-01

Background Dental care is the most common unmet health care need for children with chronic conditions. However, anecdotal evidence suggests that not all children with chronic conditions encounter difficulties accessing dental care. The goals of this study are to evaluate dental care use for Medicaid-enrolled children with chronic conditions and to identify the subgroups of children with chronic conditions that are the least likely to use dental care services. Methods This study focused on children with chronic conditions ages 3-14 enrolled in the Iowa Medicaid Program in 2005 and 2006. The independent variables were whether a child had each of the following 10 body system-based chronic conditions (no/yes): hematologic; cardiovascular; craniofacial; diabetes; endocrine; digestive; ear/nose/throat; respiratory; catastrophic neurological; or musculoskeletal. The primary outcome measure was use of any dental care in 2006. Secondary outcomes, also measured in 2006, were use of diagnostic dental care, preventive dental care, routine restorative dental care, and complex restorative dental care. We used Poisson regression models to estimate the relative risk (RR) associated with each of the five outcome measures across the 10 chronic conditions. Results Across the 10 chronic condition subgroups, unadjusted dental utilization rates ranged from 44.3% (children with catastrophic neurological conditions) to 60.2% (children with musculoskeletal conditions). After adjusting for model covariates, children with catastrophic neurological conditions were significantly less likely to use most types of dental care (RR: 0.48 to 0.73). When there were differences, children with endocrine or craniofacial conditions were less likely to use dental care whereas children with hematologic or digestive conditions were more likely to use dental care. Children with respiratory, musculoskeletal, or ear/nose/throat conditions were more likely to use most types of dental care compared to other children with chronic conditions but without these specific conditions (RR: 1.03 to 1.13; 1.0 to 1.08; 1.02 to 1.12; respectively). There was no difference in use across all types of dental care for children with diabetes or cardiovascular conditions compared to other children with chronic conditions who did not have these particular conditions. Conclusions Dental utilization is not homogeneous across chronic condition subgroups. Nearly 42% of children in our study did not use any dental care in 2006. These findings support the development of multilevel clinical interventions that target subgroups of Medicaid-enrolled children with chronic conditions that are most likely to have problems accessing dental care.

Children with respiratory, musculoskeletal, or ear/nose/throat conditions were more likely to use most types of dental care compared to other children with chronic conditions but without these specific conditions (RR: 1.03 to 1.13; 1.0 to 1.08; 1.02 to 1.12; respectively). There was no difference in use across all types of dental care for children with diabetes or cardiovascular conditions compared to other children with chronic conditions who did not have these particular conditions. Dental utilization is not homogeneous across chronic condition subgroups. Nearly 42% of children in our study did not use any dental care in 2006. These findings support the development of multilevel clinical interventions that target subgroups of Medicaid-enrolled children with chronic conditions that are most likely to have problems accessing dental care.

The study aimed to analyze the professional autonomy of Japanese nurses when caring for non-Japanese patients and to identify its contributing factors. A descriptive cross-sectional design was used. Participants included 238 clinical nurses working at 27 hospitals in Japan. The Intercultural Sensitivity Scale (Chen and Starosta), and the Scale for Professional Autonomy in Nursing (Kikuchi and Harada) were used to measure intercultural sensitivity and professional autonomy. Stepwise multiple regression analysis was used to identify the most significant factors affecting professional autonomy. Professional autonomy of Japanese nurses caring for non-Japanese patients was significantly lower than when caring for Japanese patients (142.84 vs. 172.85; p < .001). Contributing factors were intercultural sensitivity (p < .001), length of nurse experience (p < .05), and availability of interpretation service (p < .05). Incorporating transcultural nursing content into training programs in schools and hospitals could enhance professional autonomy of Japanese nurses by promoting intercultural sensitivity. © The Author(s) 2015.

[Celiac disease, non celiac gluten sensitivity and wheat allergy: comparison of 3 different diseases triggered by the same food].

PubMed

Ortiz, Catalina; Valenzuela, Romina; Lucero A, Yalda

2017-06-01

Gluten and other related proteins of the wheat, rye and barley, have antigenic properties that may trigger adverse reactions in susceptible individuals. Celiac disease was the first pathology with clear causal association related to the intake of these proteins. Recently, wheat allergy and non celiac gluten sensitivity have been described. Although, clinical presentation and its relation with protein ingestion may be similar and elicit confusion, their pathogenic mechanism, diagnosis and treatment are quite different. Since the prevalence of these diseases is relatively high as a whole, it is essential that these become familiar to primary care doctors and general pediatricians, thus they will know how to differentiate and face them. The aim of this review is to compare the main aspects of epidemiology, pathofisiology, diagnosis and treatment of these 3 conditions.

Developing graduate student competency in providing culturally sensitive end of life care in critical care environments - a pilot study of a teaching innovation.

Australia's immigration policy has generated a rich diverse cultural community of staff and patients in critical care environments. Many different cultural perspectives inform individual actions in the context of critical care, including the highly sensitive area of end of life care, with nurses feeling poorly prepared to provide culturally sensitive end of life care. This article describes and evaluates the effectiveness of an educational innovation designed to develop graduate-level critical care nurses' capacity for effective interpersonal communication, as members of a multi-disciplinary team in providing culturally sensitive end-of-life care. A mixed method pilot study was conducted using a curriculum innovation intervention informed by The Excellence in Cultural Experiential Learning and Leadership Program (EXCELL),(1) which is a higher education intervention which was applied to develop the nurses' intercultural communication skills. 12 graduate nursing students studying critical care nursing participated in the study. 42% (n=5) of the participants were from an international background. Information about students' cultural learning was recorded before and after the intervention, using a cultural learning development scale. Student discussions of end of life care were recorded at Week 2 and 14 of the curriculum. The quantitative data was analysed using descriptive statistical analysis and qualitative data was thematically analysed. Students demonstrated an increase in cultural learning in a range of areas in the pre-post surveys including understandings of cultural diversity, interpersonal skills, cross cultural interactions and participating in multicultural groups. Thematic analysis of the end of life discussions revealed an increase in the levels of nurse confidence in approaching end of life care in critical care environments. The EXCELL program provides an effective and supportive educational framework to increase graduate nurses' cultural learning development and competence to manage culturally complex clinical issues such as end of life care, and is recommended as a framework for health care students to learn the skills required to provide culturally competent care in a range of culturally complex health care settings.

False-positive tangible outcomes of functional analyses.

PubMed

Rooker, Griffin W; Iwata, Brian A; Harper, Jill M; Fahmie, Tara A; Camp, Erin M

2011-01-01

Functional analysis (FA) methodology is the most precise method for identifying variables that maintain problem behavior. Occasionally, however, results of an FA may be influenced by idiosyncratic sensitivity to aspects of the assessment conditions. For example, data from several studies suggest that inclusion of a tangible condition during an FA may be prone to a false-positive outcome, although the extent to which tangible reinforcement routinely produces such outcomes is unknown. We examined susceptibility to tangible reinforcement by determining whether a new response was acquired more readily when exposed to a tangible contingency relative to others commonly used in an FA (Study 1), and whether problem behavior known not to have a social function nevertheless emerged when exposed to tangible reinforcement (Study 2). Results indicated that inclusion of items in the tangible condition should be done with care and that selection should be based on those items typically found in the individual's environment.

Positive and negative variations in capacitive images for given defects under varying experimental conditions

Capacitive imaging (CI) technique is a novel electromagnetic NDE technique. The Quasi-static electromagnetic field from the carefully designed electrode pair will vary when the electrical properties of the sample change, leading to the possibility of imaging. It is observed that for a given specimen, the targeted features appear as different variations in capacitive images under different experimental conditions. In some cases, even opposite variations occur, which brings confusion to indication interpretation. It is thus thought interesting to embark on investigations into the cause and effects of the negative variation phenomenon. In this work, the positive and negative variations were first explained from the measurement sensitivity distribution perspective. This was then followed by a detailed analysis using finite element models in COMSOL. A parametric experimental study on a glass fiber composite plate with artificial defects was then carried out to investigate how the experimental conditions affect the variation.

Background: Migration is associated with an increase of multicultural care settings. The acceptance of such care relations from user’s point of view has been rarely explored yet. Aim: It is examined, if and how elderly migrants from Turkey consider a common migration background respectively a common socio-cultural background of caregivers as relevant. Method: In terms of data triangulation results of a qualitative study and a quantitative study on care expectations of elderly migrants from Turkey have been merged. Data was collected by means of guideline-based and standardised interviews. Analysis included the documentary method according to Bohnsack as well as descriptive and multivariate methods. Results: Cultural and migration-related aspects are considered relevant by the vast majority of respondents. Turkish language skills of caregivers are important to more than three-quarters. According to qualitative results, the possibility to objective as well as culturally shaped intuitive communication in the mother tongue is crucial. Correspondingly, a low level of German language skills and a Turkish ethnic identity are associated with a need of migration-sensitive care. Conclusions: A common socio-cultural background with caregivers and the common mother tongue appear to be prerequisites of good care for elderly migrants from Turkey. Further research should examine the conditions under which multicultural care settings are accepted in this group.

Apomorphine conditioning and sensitization: the paired/unpaired treatment order as a new major determinant of drug conditioned and sensitization effects.

Repeated treatments with psychostimulant drugs generate behavioral sensitization. In the present study we employed a paired/unpaired protocol to assess the effects of repeated apomorphine (2.0 mg/kg) treatments upon locomotion behavior. In the first experiment we assessed the effects of conditioning upon apomorphine sensitization. Neither the extinction of the conditioned response nor a counter-conditioning procedure in which we paired an inhibitory treatment (apomorphine 0.05 mg/kg) with the previously established conditioned stimulus modified the sensitization response. In the second experiment, we administered the paired/unpaired protocol in two phases. In the second phase, we reversed the paired/unpaired protocol. Following the first phase, the paired group alone exhibited conditioned locomotion in the vehicle test and a sensitization response. In the second phase, the initial unpaired group which received 5 paired apomorphine trials during the reversal phase did not develop a conditioned response but developed a potentiated sensitization response. This disassociation of the conditioned response from the sensitization response is attributed to an apomorphine anti-habituation effect that can generate a false positive Pavlovian conditioned response effect. The potentiated sensitization response induced by the treatment reversal protocol points to an important role for the sequential experience of the paired/unpaired protocol in behavioral sensitization. 2010 Elsevier Inc.

2007-01-01

The most striking feature of the management of patients with cardiovascular disease (CVD) in India, is its heterogeneity: from patients treated at tertiary and teaching hospitals, who receive the best possible evidence‐based care, to patients who have poor or, even no, access to specialist care and whose condition, therefore, is poorly treated. The challenge for Indian healthcare lies in righting this imbalance. One step in this direction would be to document practice patterns in representative treating hospitals in different regions of the country, to identify the strengths and weaknesses of the system. Resource‐sensitive guidelines incorporating evidence‐based, cost‐effective treatments should be widely disseminated. Large‐scale efforts to improve general awareness about CVD and its risk factors, and to promote healthy lifestyles, should be undertaken, and the consumption of tobacco products and unhealthy foods discouraged.

The intriguing observation that leptin decreases sweet-evoked peripheral gustatory responses has aroused much interest (Kawai K, Sugimoto K, Nakashima K, Miura H, Ninomiya Y. 2000. Leptin as a modulator of sweet taste sensitivities in mice. Proc Natl Acad Sci U S A. 97(20):11044-11049.) due to its implied importance in controlling appetite. The effects of this anorexic hormone, however, appear more conditional than originally believed. In this issue of Chemical Senses, a careful study by Glendinning and colleagues, find no effects of leptin on sweet-evoked chorda tympani responses, whereas an equally careful study by Meredith and colleagues, find decreased release of ATP and increased release of 5-HT from taste buds in response to sweet stimuli. © The Author 2015.

Shimamura, Atsuko; Suwa, Sayuri; Tsujimura, Mayuko

2016-04-01

This study aimed to explore how visiting nurses in Japan sense Kuuki (mood or atmosphere) in the homes of patients and families. Participants were 15 Japanese visiting nurses with experience sensing kuuki in homes of patients and families. Data were collected through two 90 min focus group interviews with experienced visiting nurses, and a qualitative content analysis was performed. The qualitative analysis showed that experienced visiting nurses sensed kuuki in eight ways. Kuuki differs based on type of illness, state of health and number of visits. Sensitivity to kuuki is thought to be linked to understanding of patient and family feelings, changes in the physical condition of patients and evaluation of nursing care delivery. Perception of kuuki also contributes to care planning especially on the very first home visit and when visiting terminally ill patients. © 2016 Wiley Publishing Asia Pty Ltd.

The objective of this study was to examine the sensitivity and specificity of a performance-based measure of functional capacity, the UCSD Performance-Based Skills Assessment (UPSA) for the prediction of independent living status in patients with chronic schizophrenia-related conditions. A sample of 434 adults with schizophrenia or schizoaffective disorder was administered the UPSA and assessed for independent living status. Participants were classified as “independent” if they were living alone in an apartment, house, or single-resident occupancy (e.g., hotel room) and non-independent if they resided in a care facility (e.g., Board-and-Care home, Skilled Nursing Facility). Receiver Operator Characteristic (ROC) curves were calculated with the UPSA and Mattis’ Dementia Rating Scale (DRS) scores as predictor variables and residential independence as the state variable. Of the 434 participants, 99 (23%) were living independently at the time of assessment. The discriminant validity of the UPSA was adequate (ROC area under the curve = 0.74; 95% CI: 0.68–0.79), with greatest dichotomization for the UPSA at a cutoff score of 75 (68% accuracy, 69% sensitivity, 66% specificity), or 80 (68% accuracy, 59% sensitivity, 76% specificity). The UPSA was also a significantly better predictor of living status than was the DRS, based on ROC (z = 2.43, p = .015). The UPSA is a brief measure of functional capacity that predicts the ability of patients with schizophrenia to reside independently in the community. PMID:17303168

A point-of-care rapid test (POCRT) may help early and targeted use of antiviral drugs for the management of influenza A infection. (i) To determine whether antiviral treatment based on a POCRT for influenza A is cost-effective and, (ii) to determine the thresholds of key test parameters (sensitivity, specificity and cost) at which a POCRT based-strategy appears to be cost effective. An hybrid « susceptible, infected, recovered (SIR) » compartmental transmission and Markov decision analytic model was used to simulate the cost-effectiveness of antiviral treatment based on a POCRT for influenza A in the social perspective. Data input parameters used were retrieved from peer-review published studies and government databases. The outcome considered was the incremental cost per life-year saved for one seasonal influenza season. In the base-case analysis, the antiviral treatment based on POCRT saves 2 lives/100,000 person-years and costs $7600 less than the empirical antiviral treatment based on clinical judgment alone, which demonstrates that the POCRT-based strategy is dominant. In one and two way-sensitivity analyses, results were sensitive to the POCRT accuracy and cost, to the vaccination coverage as well as to the prevalence of influenza A. In probabilistic sensitivity analyses, the POCRT strategy is cost-effective in 66% of cases, for a commonly accepted threshold of $50,000 per life-year saved. The influenza antiviral treatment based on POCRT could be cost-effective in specific conditions of performance, price and disease prevalence. © 2015 The Authors.

Occupational exposure of hairdressers to hair dyes has been associated with the development of allergic contact dermatitis (ACD) involving the hands. p-Phenylenediamine (PPD) and toluene-2,5-diamine (PTD) have been implicated as important occupational contact allergens. To conduct a quantitative risk assessment for the induction of contact sensitization to hair dyes in hairdressers, available data from hand rinsing studies following typical occupational exposure conditions to PPD, PTD and resorcinol were assessed. By accounting for wet work, uneven exposure and inter-individual variability for professionals, daily hand exposure concentrations were derived. Secondly, daily hand exposure was compared with the sensitization induction potency of the individual hair dye defined as the No Expected Sensitization Induction Levels (NESIL). For PPD and PTD hairdresser hand exposure levels were 2.7 and 5.9 fold below the individual NESIL. In contrast, hand exposure to resorcinol was 50 fold below the NESIL. Correspondingly, the risk assessment for PPD and PTD indicates that contact sensitization may occur, when skin protection and skin care are not rigorously applied. We conclude that awareness of health risks associated with occupational exposure to hair dyes, and of the importance of adequate protective measures, should be emphasized more fully during hairdresser education and training.

Considering the senses in the diagnosis and management of dementia.

PubMed

Behrman, Sophie; Chouliaras, Leonidas; Ebmeier, Klaus P

2014-04-01

Associations between dementia and impairments in hearing, vision, olfaction and (to a lesser degree) taste have been identified. Hearing impairment has been shown to precede cognitive decline, but it is not clear if the hearing loss is an early marker of dementia or a modifiable risk factor. Olfactory impairment is seen in many neurodegenerative conditions, but it has been shown that those with dementia have particular difficulties with the recognition and identification of odours rather than the detection, suggesting a link to impairment of higher cognitive function. Olfactory impairment has been shown to be predictive of conversion from mild cognitive impairment to Alzheimer's disease with 85.2% sensitivity. As cognitive function deteriorates, the world is experienced at a sensory level, with reduced ability to integrate the sensory experiences to understand the context. Thus, people with dementia are very sensitive to sensory experiences and their environment needs to be managed carefully to make it understandable, comfortable, and (if possible) therapeutic. Light can be used to stabilise the circadian rhythm, which may be disturbed in dementia. Music therapy, aromatherapy, massage and multisensory stimulation are recommended by NICE for the management of behavioural and psychological symptoms of dementia (BPSD), although the mechanisms behind such interventions are poorly understood and evidence is limited. Sensory considerations are likely to play a greater role in dementia care in the future, with the development of purpose-built dementia care facilities and the focus on non-pharmacological management strategies for BPSD.

The purpose of this study was to define and characterize episodes of chiropractic care among older Medicare beneficiaries and to evaluate the extent to which chiropractic services were used in tandem with conventional medicine. Medicare Part B claims histories for 1991 to 2007 were linked to the nationally representative survey on Assets and Health Dynamics among the Oldest Old baseline interviews (1993-1994) to define episodes of chiropractic sensitive care using 4 approaches. Chiropractic and nonchiropractic patterns of service use were examined within these episodes of care. Of the 7447 Assets and Health Dynamics among the Oldest Old participants, 971 used chiropractic services and constituted the analytic sample. There were substantial variations in the number and duration of episodes and the type and volume of services used across the 4 definitions. Depending on how the episode was constructed, the mean number of episodes per chiropractic user ranged from 3.74 to 23.12, the mean episode duration ranged from 4.7 to 28.8 days, the mean number of chiropractic visits per episode ranged from 0.88 to 2.8, and the percentage of episodes with co-occurrent use of chiropractic and nonchiropractic providers ranged from 4.9% to 10.9% over the 17-year period. Treatment for back-related musculoskeletal conditions was sought from a variety of providers, but there was little co-occurrent service use or coordinated care across provider types within care episodes. Chiropractic treatment dosing patterns in everyday practice were much lower than that used in clinical trial protocols designed to establish chiropractic efficacy for back-related conditions.

Detection beyond the Debye screening length in a high-frequency nanoelectronic biosensor.

2012-02-08

Nanosensors based on the unique electronic properties of nanotubes and nanowires offer high sensitivity and have the potential to revolutionize the field of Point-of-Care (POC) medical diagnosis. The direct current (dc) detection of a wide array of organic and inorganic molecules has been demonstrated on these devices. However, sensing mechanism based on measuring changes in dc conductance fails at high background salt concentrations, where the sensitivity of the devices suffers from the ionic screening due to mobile ions present in the solution. Here, we successfully demonstrate that the fundamental ionic screening effect can be mitigated by operating single-walled carbon nanotube field effect transistor as a high-frequency biosensor. The nonlinear mixing between the alternating current excitation field and the molecular dipole field can generate mixing current sensitive to the surface-bound biomolecules. Electrical detection of monolayer streptavidin binding to biotin in 100 mM buffer solution is achieved at a frequency beyond 1 MHz. Theoretical modeling confirms improved sensitivity at high frequency through mitigation of the ionic screening effect. The results should promise a new biosensing platform for POC detection, where biosensors functioning directly in physiologically relevant condition are desired. © 2012 American Chemical Society

In December 2014, the Federal Health Reporting published the first official report on men's health in Germany. The report covers a wide range of topics, from diseases and causes of death to health-related behaviors and male-specific prevention. Special chapters put the focus on the impact that working life and certain living arrangements may have on health. Based on preliminary methodological work on gender-sensitive health reporting, a step-wise approach was pursued. In addition to mere comparisons between men and women, differences within men were taken into account with respect to certain stressors, risks and resources. Moreover, guided by theory, findings were interpreted and discussed in the context of changing political and societal conditions. In the present article, the project team takes a critical look at its work: What steps towards sex- and gender-sensitive health reporting could be taken? And to what extent does the current approach leave room for improvement? In contributing to a better description of the health of men and women, gender-sensitive health reporting may provide a sound empirical basis for the implementation of gender-appropriate health care.

Assuring the sufficiency and suitability of systems of care and services for children with special health care needs (CSHCN) presents a challenge to Texas providers, agencies, and state Title V programs. To meet the need for specialist care, referrals from primary care doctors are often necessary. The objective of this study was to describe the factors associated with the need for specialist care and problems associated with obtaining referrals in Texas. Bivariate and multivariate analyses were performed using the National Survey of Children with Special Health Care Needs (NS-CSHCN) weighted sample for Texas (n = 719,014) to identify variables associated with the need for specialist care and problems obtaining referrals for specialist care. Medical need of the CSHCN and sensitivity to family values/customs was associated with greater need for specialist care, and Hispanic ethnicity and lower maternal education were associated with less need. Medical need, amount of time spent with doctors and sensitivity to values/customs, living in a large metropolitan statistical area, and lack of medical information were associated with problems obtaining a specialist care referral. Findings revealed some similarities and differences with meeting the need for specialist care when comparing Texas results to other studies. In Texas, aspects of customer satisfaction variables, especially doctors' sensitivity to family values/customs and parents' not receiving enough information on medical problems, were significantly associated with problems obtaining specialist referrals. Findings indicate a need to further research relationships and communication among doctors, CSHCN, and their families.

From a public health perspective, primary care medical settings represent a strategic location to address mental health disapirty among Latinos. Yet, there is little empirical work that addresses affective vulnerability processes for mental health problems in such settings. To help address this gap in knowledge, the present investigation examined an interactive model of negative affectivity (tendency to experience negative mood states) and anxiety sensitivity (fear of the negative consequences of aversive sensations) among a Latino sample in primary care in terms of a relatively wide range of anxiety/depression indices. Participants included 390 Latino adults (Mage=38.7, SD=11.3; 86.9% female; 95.6% reported Spanish as first language) from a primary care health clinic. Primary dependent measures included depressive, suicidal, social anxiety, and anxious arousal symptoms, number of mood and anxiety disorders, and disability. Consistent with prediction, the interaction between negative affectivity and anxiety sensitivity was significantly related to suicidal, social anxiety, and anxious arousal symptoms, as well as number of mood/anxiety diagnoses and disability among the primary care Latino sample. The form of the interactions indicated a synergistic effect, such that the greatest levels of each outcome were found among those with high negative affectivity and high anxiety sensitivity. There was a trending interaction for depressive symptoms. Overall, these data provide novel empirical evidence suggesting that there is a clinically-relevant interplay between anxiety sensitivity and negative affectivity in regard to the expression of anxiety and depressive symptoms among a Latino primary care sample.

This indicates that maternal care is triggered by sensory stimulation provided by the pups and that its onset is largely independent on the physiological events related to gestation, parturition and lactation. Conversely, the factors influencing maternal aggression are poorly understood. In this study, we sought to characterize two models of maternal sensitization in the outbred CD1 strain. To do so, a group of virgin females (godmothers) were exposed to continuous cohabitation with a lactating dam and their pups from the moment of parturition, whereas a second group (pup-sensitized females), were exposed 2 h daily to foster pups. Both groups were tested for maternal behavior on postnatal days 2-4. Godmothers expressed full maternal care from the first test. Also, they expressed higher levels of crouching than dams. Pup-sensitized females differed from dams in all measures of pup-directed behavior in the first test, and expressed full maternal care after two sessions of contact with pups. However, both protocols failed to induce maternal aggression toward a male intruder after full onset of pup-directed maternal behavior, even in the presence of pups. Our study confirms that adult female mice need a short sensitization period before the onset of maternal care. Further, it shows that pup-oriented and non-pup-oriented components of maternal behavior are under different physiological control. We conclude that the godmother model might be useful to study the physiological and neural bases of the maternal behavior repertoire.

Being outdoors may have health benefits including being more physically active. Understanding the relationship between outdoor time and health is hampered by the difficulty of measuring outdoor time. To examine the accuracy and validity of light-sensor and GPS methods for quantifying outdoor time among those aged 3-5 years at child care. A total of 45 children (mean age 4.5 years, 64% boys) from five child care centers wore portable accelerometers with built-in light sensors and a separate GPS device around their waists during child care, providing 80,648 episodes (15 seconds each) for analysis. Direct observation (gold standard) of children being outdoors versus indoors was conducted for 2 days at each center. GPS signal-to-noise ratios, processed through the Personal Activity and Location Measurement System were used to define indoor versus outdoor locations. Receiver operating characteristic (ROC) analyses were used to determine thresholds for defining being indoors versus outdoors. Data were collected in Fall 2011, analyzed in 2012. Mean observed outdoor time was 63 [±44; range: 18-152] minutes/day. Mean light-sensor levels were significantly higher outdoors. The area under the ROC curve for location based on light sensor for all weather conditions was 0.82 (range: 0.70 on partly cloudy days to 0.97 on sunny days); for GPS, it was 0.89. The light sensor had a sensitivity of 74% and specificity of 86%. GPS had a sensitivity of 82% and specificity of 88%. A light sensor and a GPS device both distinguish indoor from outdoor time for preschoolers with moderate to high levels of accuracy. These devices can increase the feasibility and lower the cost of measuring outdoor time in studies of preschool children. Copyright © 2013 American Journal of Preventive Medicine.

Satisfaction is an important measure of care quality. Interventions to improve satisfaction in the pediatric emergency department (ED) are limited, especially for patients with nonurgent conditions. Our objective was to determine if clinician knowledge of written parental expectations improves parental satisfaction for nonurgent ED visits. This randomized controlled trial was conducted in a tertiary-care pediatric ED. Parents of children presenting for nonurgent visits (Emergency Severity Index level 4 or 5) were randomized into 3 groups: 1) the intervention group completed an expectation survey on arrival, which was reviewed by the clinician, 2) the control group completed the expectation survey, which was not reviewed, and 3) the baseline group did not complete an expectation survey. At ED disposition, all groups completed a 3-item satisfaction survey, scored using 5-point Likert scales (1 = very poor, 5 = very good). The primary outcome was rating of "overall care." Secondary outcomes included likelihood of recommending the ED and staff sensitivity to concerns. Proportions were compared by chi-square test. A total of 304 subjects were enrolled. The proportion of parents rating 5 of 5 for overall care did not differ among the baseline, control, and intervention groups (74.8% vs 73.2% vs 69.2%, P = .56). The proportion of parents rating 5 of 5 also did not differ for likelihood of recommending the ED (77.7% vs 72.2% vs 70.2%, P = .45) or staff sensitivity to concerns (78.6% vs 78.4% vs 78.8%, P = .71). For nonurgent pediatric ED visits, clinician knowledge of written parental expectations does not improve parental satisfaction. Copyright © 2016 Academic Pediatric Association.

Carbapenemase-producing Enterobacteriaceae are increasing worldwide. Rectal screening for these bacteria can inform the management of infected and colonized patients, especially those admitted to intensive care units (ICUs). A laboratory developed, qualitative duplex real-time polymerase chain reaction assay for rapid detection of OXA-48-like and VIM producing Enterobacteriaceae, performed on rectal swabs, was designed and evaluated in an intensive care unit with endemic presence of OXA-48. During analytical assay validation, no cross-reactivity was observed and 100% sensitivity and specificity were obtained for both bla OXA-48-like and bla VIM in all spiked clinical samples. During the clinical part of the study, the global sensitivity and specificity of the real-time PCR assay for OXA-48 detection were 95.7% and 100% (P=0.1250), respectively, in comparison with culture; no VIM-producing Enterobacteriaceae were detected. Clinical features of patients in the ICU who were colonized or infected with OXA-48 producing Enterobacteriaceae, including outcome, were analyzed. Most had severe underlying conditions, and had risk factors for colonization with carbapenemase-producing Enterobacteriaceae before or during ICU admission, such as receiving previous antimicrobial therapy, prior healthcare exposure (including long-term care), chronic disease, immunosuppression and/or the presence of an intravascular catheter and/or mechanical ventilation device. The described real-time PCR assay is fast (~2-3hours, if DNA extraction is included), simple to perform and results are easy to interpret, features which make it applicable in the routine of clinical microbiology laboratories. Implementation in endemic hospitals could contribute to early detection of patients colonized by OXA-48 producing Enterobacteriaceae and prevention of their spread. Copyright © 2017 Elsevier Inc.

Hepatitis C (HCV) is a viral infection that if left untreated can severely damage the liver. Project INSPIRE was a 3 year HCV care coordination programme in New York City (NYC) that aimed to address barriers to treatment initiation and cure by providing patients with supportive services and health promotion. We examined whether enrolment in Project INSPIRE was associated with differences in HCV treatment and cure compared with a demographically similar group not enrolled in the programme. INSPIRE participants in 2015 were matched with a cohort of HCV-infected persons identified in the NYC surveillance registry, using full optimal matching on propensity scores and stratified by INSPIRE enrolment status. Conditional logistic regression was used to assess group differences in the two treatment outcomes. Two follow-up sensitivity analyses using individual pair-matched sets and the full unadjusted cohort were also conducted. Treatment was initiated by 72% (790/1130) of INSPIRE participants and 36% (11 960/32 819) of study-eligible controls. Among initiators, 65% (514/790) of INSPIRE participants compared with 47% (5641/11 960) of controls achieved cure. In the matched analysis, enrolment in INSPIRE increased the odds of treatment initiation (OR: 5.25, 95% CI: 4.47-6.17) and cure (OR: 2.52, 95% CI: 2.00-3.16). Results from the sensitivity analyses showed agreement with the results from the full optimal match. Participation in the HCV care coordination programme significantly increased the probability of treatment initiation and cure, demonstrating that care coordination for HCV-infected individuals improves treatment outcomes. © 2018 John Wiley & Sons Ltd.

Social support plays a critical role in how women living with breast cancer deal with their diagnosis and treatment. This article discusses the meanings of breast cancer and the experiences of social support among women living with breast cancer in Northeastern Thailand (Isan). In-depth interviews were conducted with 18 women with breast cancer. Data were analysed using the thematic analysis method. Being diagnosed with breast cancer can be a traumatic experience. However, many women with breast cancer managed to deal with their illnesses and treatments and this was based largely on social support they received. Available support from family members, friends, neighbours, religion and health care professionals was essential for them to deal with their breast cancer. Social support was an important component for the provision of good care for these women and women living with breast cancer. Although medical treatments were essential for breast cancer, social support could enhance the effectiveness of the treatments as it helped women to have positive perspectives about their health conditions and to better deal with their illnesses. Our findings are useful for sensitive health promotion for women with breast cancer in Thailand and elsewhere. Social support should be modified to meet the woman's individual needs. Health professionals are an important source of social support for women with breast cancer. Having an understanding and being sensitive to these women's experiences and challenges means that health care professionals can provide more individualised support and care to women during their vulnerable period of life. © The Author 2015.

Psychostimulant sensitization heightens behavioral and motivational responses to reward-associated stimuli; however, its effects on stimuli associated with reward absence are less understood. We examined whether amphetamine sensitization alters performance during Pavlovian-instrumental transfer (PIT) to conditioned excitors and inhibitors. We further sought to characterize the effects of amphetamine sensitization on learning versus performance by exposing rats to amphetamine prior to Pavlovian training or between training and test. Adult male Long-Evans rats were given conditioned inhibition (A+/AX-) and Pavlovian (B+) training, followed by variable-interval instrumental conditioning. Rats were sensitized to D-amphetamine (2 mg/kg daily injections for 7 days) or served as non-exposed controls. Rats were given a PIT test, in which they were presented with stimulus B alone or in compound with the conditioned inhibitor (BX). During the PIT test, control rats significantly reduced instrumental responding on BX trials (to approximately 50 % of responding to B). Amphetamine sensitization prior to Pavlovian conditioning increased lever pressing on BX trials and reduced lever pressing on B trials compared to controls. Amphetamine sensitization between training and test increased lever pressing on B and BX trials compared to controls. No effects of sensitization were observed on conditioned food cup approach. Amphetamine sensitization increases instrumental responding during PIT to a conditioned inhibitor by enhancing the excitation of conditioned stimuli and reducing the inhibition of conditioned inhibitors.

The preventive health care needs of people with disabilities often go unmet, resulting in medical complications that may require hospitalization. Such complications could be due, in part, to difficulty accessing care or the quality of ambulatory care services received. To use hospitalizations for urinary tract infections (UTIs) as a marker of the potential quality of ambulatory care services received by people affected by spina bifida. MarketScan inpatient and outpatient medical claims data for 2000 through 2003 were used to identify hospitalizations for UTI, which is an ambulatory care sensitive condition, for people affected by spina bifida and to calculate inpatient discharge rates, average lengths of stay, and average medical care expenditures for such hospitalizations. People affected by spina bifida averaged 0.5 hospitalizations per year, and there were 22.8 inpatient admissions with UTI per 1000 persons with spina bifida during the period 2000-2003, in comparison to an average of 0.44 admission with UTI per 1000 persons for those without spina bifida. If the number of UTI hospitalizations among people affected by spina bifida were reduced by 50%, expenditures could be reduced by $4.4 million per 1000 patients. Consensus on the evaluation and management of bacteriuria could enhance clinical care and reduce the disparity in UTI discharge rates among people affected by spina bifida compared to those without spina bifida. National evidence-based guidelines are needed.

Nursing-sensitive indicators: a concept analysis

Aim To report a concept analysis of nursing-sensitive indicators within the applied context of the acute care setting. Background The concept of ‘nursing sensitive indicators’ is valuable to elaborate nursing care performance. The conceptual foundation, theoretical role, meaning, use and interpretation of the concept tend to differ. The elusiveness of the concept and the ambiguity of its attributes may have hindered research efforts to advance its application in practice. Design Concept analysis. Data sources Using ‘clinical indicators’ or ‘quality of nursing care’ as subject headings and incorporating keyword combinations of ‘acute care’ and ‘nurs*’, CINAHL and MEDLINE with full text in EBSCOhost databases were searched for English language journal articles published between 2000–2012. Only primary research articles were selected. Methods A hybrid approach was undertaken, incorporating traditional strategies as per Walker and Avant and a conceptual matrix based on Holzemer's Outcomes Model for Health Care Research. Results The analysis revealed two main attributes of nursing-sensitive indicators. Structural attributes related to health service operation included: hours of nursing care per patient day, nurse staffing. Outcome attributes related to patient care included: the prevalence of pressure ulcer, falls and falls with injury, nosocomial selective infection and patient/family satisfaction with nursing care. Conclusion This concept analysis may be used as a basis to advance understandings of the theoretical structures that underpin both research and practical application of quality dimensions of nursing care performance.

Moral sensitivity refers to the interpretive awareness of moral conflict and can be justice or care oriented. Justice ethics is associated primarily with human rights and the application of moral rules, whereas care ethics is related to human needs and a situational approach involving social emotions. Among the core brain regions involved in moral issue processing are: medial prefrontal cortex, anterior (ACC) and posterior (PCC) cingulate cortex, posterior superior temporal sulcus (pSTS), insula and amygdala. This study sought to inform the long standing debate of whether care and justice moral ethics represent one or two different forms of cognition. Model-free and model-based connectivity analysis were used to identify functional neural networks underlying care and justice ethics for a moral sensitivity task. In addition to modest differences in patterns of associated neural activity, distinct modes of functional and effective connectivity were observed for moral sensitivity for care and justice issues that were modulated by individual variation in moral ability. These results support a neurobiological differentiation between care and justice ethics and suggest that human moral behavior reflects the outcome of integrating opposing rule-based, self-other perspectives, and emotional responses.

Spina bifida is a common cause of pediatric disability and more prevalent in the Hispanic population. Significant health disparities exist in minority populations. Culturally adapted health interventions have been attempted in conditions such as pediatric asthma with improvement. This study aims to explore the influence of ethnicity and culture with regards to functional status and care satisfaction. Study participants were recruited from the Children's Hospital Colorado Spinal Defects Clinic. Demographics and past medical and surgical history were obtained via chart review. A questionnaire assessed ethnicity, acculturation, self-care, mobility, bowel and bladder function, and care satisfaction. A total of 70 subjects with spina bifida were included in the statistical analysis. There was no difference in PEDI self-care and mobility scores between ethnicities. The Hispanic group had higher urinary incontinence rates, higher percentage with bladder accidents, and lower satisfaction with bladder management. Regarding bowel function, the Hispanic group had lower satisfaction rates and a trend towards lower bowel continence. Further work is needed to understand the social and cultural differences between Hispanic and Non-Hispanic children and their families that impact bowel and bladder continence and care satisfaction. Once identified, culturally sensitive interventions may be implemented that can alleviate these apparent health disparities.

in year 2008 the Ausl of Ravenna had a small number of patients at risk among the patients fallen, and among the patients evaluated with risk for fall. This could be due to the rating scale used (Conley) that does not recognize the risk factors "drug therapy" and "conditions clinical care". to experiment a rating scale (Mosaic), to evaluate the performance indicators compared to the scales Conley, Fall Risk Assessment Scoring System (FRASS), Stratity; evaluate the effectiveness of actions taken to manage the risk; Operators remain vigilant about the risk falls. using the scale Mosaic for patients admitted in 16 Hospital Units for two-months. Performance indicators: sensitivity, specificity, positive predictive value and negative. Studies considered for comparison: Hospital (AO) Bologna for Conley, AO Bologna and AO Niguarda Cà Granda Milan for Stratify, AO Bergamo for FRASS. were analyzed 1474 tabs. Males are 848 (57.5%) and females 626 (43.5%), the average age is 70.8 years. Of these 42 patients have fallen (2.8%), including 25 males and 17 females and the average age is 72.2. Are not at risk 426 (29%) patients and at risk 1048 (71%) patients. In other assessments the patients at risk was 31% in AUSL Ravenna, 59% (Conley) and 13% (Stratify) in AO Bologna and 41.5% (FRASS) in AO Bergamo. The scale Mosaic has a sensitivity of 0.98 (Conley, Stratify and FRASS amounted to 0.69, to 0.20, to 0.50), a specificity of 0.30 (Conley, Stratify and FRASS amounted to 0.41, 0.87, 0.59.) The patients fallen are at risk in 41 cases (97%) and of these 24 low-risk. The most frequent risk factors are: "mobility and gait" (1209 items), "drug therapy" (850 items) , "conditions clinical care" (841 items). Planned actions have an average of 2.2 in patients fallen, of 3.5 in low-risk patients and of 4.48 in patients at high risk. Compared with the previous year shows a decrease of 14 falls and an increase in the level of outcome "no one" (from 61% to 73.5%). the greater number of falls occur among low-risk patients, the average number of shares increases with increasing levels of risk and decreases in the patients fallen. Patients are at increased risk and therefore, in the hospital, it is essential to evaluate the factors drug therapy and conditions clinical care. The scale Mosaic has a very good performance for the sensitivity but not the specificity. The indicators in the studies are very different. This poses a reflection: what is the sense of the indicators when the rated instrument is part of a multifactorial prevention project whose implementation, usually, improves the level of security by preventing the occurrence of the event? Analysis of the tool can not be based only on numerical data. The true value of each scale is the level of attention that triggers in Health Care Workers, which activate preventive measures that allow an efficient management of risk. the card Mosaic has been adopted in Ausl because it improved the level of security of patients with risk of fall.

Case-control study analyzing the risk of hospitalization for HF. The exposure factor was the process of care for HF in primary health. Health area of the region of Madrid (n=466.901). There were included all adult patients (14 years or older) with a documented diagnosis of HF in the electronic medical record of primary health (n=3.277). The cases were patients who were hospitalized for HF while the controls did not require admission, during 2007. risk of ACSH for HF related to the process of care considered both overall and for each separate standard of appropiate care. Differences in clinical complexity of the groups were measured using the Adjusted Clinical Group (ACG) classification system. 227 cases and 3.050 controls. Clinical complexity was greater in cases. The standards of appropriate care were met to a greater degree in the control group, but none of the two groups met all the standards that would define a process of care as fully appropriate. A significantly lower risk of ACSH was seen for only two standards of appropriate care. For each additional standard of appropriate care not met, the probability of admission was significantly greater (OR: 1,33, 95% CI: 1,19-1,49). Higher quality in the process of care in primary health was associated with a lower risk of hospitalization for HF. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

The multidisciplinary management of patients following pharyngolaryngeal surgery is an essential condition for its functional and socio-professional success. Early, overall rehabilitation, geared to each type of exeresis and to the personality of each patient, will enable both the voice and swallowing to regain their autonomy. A series of 195 patients after partial or reconstructive laryngectomy or pharyngectomy is analysed. The maintenance of a functional crico-arytenoid unity, the preservation of the mucosal sensitivity, the establishment of a facilitating posture and the dynamisation of the neoglottic sphincter are all equally important elements requiring the mobilisation of the entire health care team.

Use of personal care products is widespread in the United States but tends to be greater among African Americans than whites. Of special concern is the possible hazard of absorption of chemicals with estrogenic activity (EA) or anti-EA (AEA) in these products. Such exposure may have adverse health effects, especially when it occurs during developmental windows (e.g., prepubertally) when estrogen levels are low. We assessed the ethanol extracts of eight commonly used hair and skin products popular among African Americans for EA and AEA using a cell proliferation assay with the estrogen sensitive MCF-7:WS8 cell line derived from a human breast cancer. Four of the eight personal care products tested (Oil Hair Lotion, Extra-dry Skin Lotion, Intensive Skin Lotion, Petroleum Jelly) demonstrated detectable EA, whereas three (Placenta Hair Conditioner, Tea-Tree Hair Conditioner, Cocoa Butter Skin Cream) exhibited AEA. Our data indicate that hair and skin care products can have EA or AEA, and suggest that laboratory studies are warranted to investigate the in vivo activity of such products under chronic exposure conditions as well as epidemiologic studies to investigate potential adverse health effects that might be associated with use of such products.

The robustness of epidemiological research using routinely collected primary care electronic data to support policy and practice for common mental disorders (CMD) anxiety and depression would be greatly enhanced by appropriate validation of diagnostic codes and algorithms for data extraction. We aimed to create a robust research platform for CMD using population-based, routinely collected primary care electronic data. We developed a set of Read code lists (diagnosis, symptoms, treatments) for the identification of anxiety and depression in the General Practice Database (GPD) within the Secure Anonymised Information Linkage Databank at Swansea University, and assessed 12 algorithms for Read codes to define cases according to various criteria. Annual incidence rates were calculated per 1000 person years at risk (PYAR) to assess recording practice for these CMD between January 1(st) 2000 and December 31(st) 2009. We anonymously linked the 2799 MHI-5 Caerphilly Health and Social Needs Survey (CHSNS) respondents aged 18 to 74 years to their routinely collected GP data in SAIL. We estimated the sensitivity, specificity and positive predictive value of the various algorithms using the MHI-5 as the gold standard. The incidence of combined depression/anxiety diagnoses remained stable over the ten-year period in a population of over 500,000 but symptoms increased from 6.5 to 20.7 per 1000 PYAR. A 'historical' GP diagnosis for depression/anxiety currently treated plus a current diagnosis (treated or untreated) resulted in a specificity of 0.96, sensitivity 0.29 and PPV 0.76. Adding current symptom codes improved sensitivity (0.32) with a marginal effect on specificity (0.95) and PPV (0.74). We have developed an algorithm with a high specificity and PPV of detecting cases of anxiety and depression from routine GP data that incorporates symptom codes to reflect GP coding behaviour. We have demonstrated that using diagnosis and current treatment alone to identify cases for depression and anxiety using routinely collected primary care data will miss a number of true cases given changes in GP recording behaviour. The Read code lists plus the developed algorithms will be applicable to other routinely collected primary care datasets, creating a platform for future e-cohort research into these conditions.

To explore the influence of workplace culture on sickness absences, overtime work and occupational injuries in municipal primary health care. The need to improve nursing sensitive outcomes has been highlighted. Therefore, an adequate understanding of the influence of workplace culture on nursing-sensitive nurse outcomes is essential for nurse managers to meet the requirements of improving nursing outcomes. A cross-sectional survey design was used to incorporating the data from 21 inpatient acute care units of nine organisations at the Finnish municipal primary health care system from 2011 to 2012. Findings emphasise in particular the importance of the practice environment as being an interpretative factor for nurses' absences owing to sickness, overtime work and occupational injuries. To ensure favourable nursing sensitive outcomes it is essential that there is a shared interest in the unit to invest in the creation of a supportive practice environment. Outcome improvements require a special focus on issues related to nursing management, adequate staffing and resources and intention to leave. © 2014 John Wiley & Sons Ltd.

To examine associations between organizational characteristics of home health agencies (eg, profit status, rehabilitation therapy staffing model, size, and rurality) and quality outcomes in Medicare beneficiaries with rehabilitation-sensitive conditions, conditions for which occupational, physical, and/or speech therapy have the potential to improve functioning, prevent or slow substantial decline in functioning, or increase ability to remain at home safely. Retrospective analysis. Home health agencies. Fee-for-service beneficiaries (N=1,006,562) admitted to 9250 Medicare-certified home health agencies in 2009. Not applicable. Institutional admission during home health care, community discharge, and institutional admission within 30 days of discharge. Nonprofit (vs for-profit) home health agencies were more likely to discharge beneficiaries to the community (odds ratio [OR], 1.23; 95% confidence interval [CI], 1.13-1.33) and less likely to have beneficiaries incur institutional admissions within 30 days of discharge (OR, .93; 95% CI, .88-.97). Agencies in rural (vs urban) counties were less likely to discharge patients to the community (OR, .83; 95% CI, .77-.90) and more likely to have beneficiaries incur institutional admissions during home health (OR, 1.24; 95% CI, 1.18-1.30) and within 30 days of discharge (OR, 1.15; 95% CI, 1.10-1.22). Agencies with contract (vs in-house) therapy staff were less likely to discharge beneficiaries to the community (OR, .79, 95% CI, .70-.91) and more likely to have beneficiaries incur institutional admissions during home health (OR, 1.09; 95% CI, 1.03-1.15) and within 30 days of discharge (OR, 1.17; 95% CI, 1.07-1.28). As payers continue to test and implement reimbursement mechanisms that seek to reward value over volume of services, greater attention should be paid to organizational factors that facilitate better coordinated, higher quality home health care for beneficiaries who may benefit from rehabilitation.

Emergency department utilization among recently released prisoners: a retrospective cohort study

PubMed Central

2013-01-01

Background The population of ex-prisoners returning to their communities is large. Morbidity and mortality is increased during the period following release. Understanding utilization of emergency services by this population may inform interventions to reduce adverse outcomes. We examined Emergency Department utilization among a cohort of recently released prisoners. Methods We linked Rhode Island Department of Corrections records with electronic health record data from a large hospital system from 2007 to 2009 to analyze emergency department utilization for mental health disorders, substance use disorders and ambulatory care sensitive conditions by ex-prisoners in the year after release from prison in comparison to the general population, controlling for patient- and community-level factors. Results There were 333,369 total ED visits with 5,145 visits by a cohort of 1,434 ex-prisoners. In this group, 455 ex-prisoners had 3 or more visits within 1 year of release and 354 had a first ED visit within 1 month of release. ED visits by ex-prisoners were more likely to be made by men (85% vs. 48%, p < 0.001) and by blacks (26% vs. 16%, p < 0.001) compared to the Rhode Island general population. Ex-prisoners were more likely to have an ED visit for a mental health disorder (6% vs. 4%, p < 0.001) or substance use disorder (16%vs. 4%, p < 0.001). After controlling for patient- and community-level factors, ex-prisoner visits were significantly more likely to be for mental health disorders (OR 1.43; 95% CI 1.27-1.61), substance use disorders (OR 1.93; 95% CI 1.77-2.11) and ambulatory care sensitive conditions (OR 1.09; 95% CI 1.00-1.18). Conclusions ED visits by ex-prisoners were significantly more likely due to three conditions optimally managed in outpatient settings. Future work should determine whether greater access to outpatient services after release from prison reduces ex-prisoners’ utilization of emergency services. PMID:24188513

Providing Palliative Care to LGBTQ Patients.

PubMed

Barrett, Nina; Wholihan, Dorothy

Nurses should be familiar with and equipped to address the challenges that arise when caring for lesbian, gay, bisexual, transgender, or queer-identified (LGBTQ) patients. LGBTQ individuals have increased rates of certain physical diseases and are at greater risk of suffering from stress-sensitive mental health issues. Negative social attitudes, widespread discrimination and stigma, physical and psychological victimization, and less social support with aging contribute to the complexity of care for these individuals. Open communication, welcoming and accepting attitudes and environments, and sensitivity to unique multidimensional issues improve care to LGBTQ patients with serious advanced illness. Nursing can reach this vulnerable minority and positively impact the quality of care. Copyright © 2016 Elsevier Inc. All rights reserved.

2017-08-31

The recent mental health care reforms in Mexico call for the regular evaluation of the services provided. This involves analyzing the opinions of those who utilize them on a daily basis, particularly women, since they are the main health service users. This study explores the barriers to mental health care perceived by a group of women attending primary care centers. A qualitative methodological approach was chosen. The participants were purposively selected, using the snowball technique. Semi-structured interviews were analyzed using the thematic analysis. Three sets of factors representing barriers to care were identified in the participants' discourse. The first is linked to systemic barriers such as a lack of familiarity with the way the service operates, and irregularities in the consultations and appointment schedules that are not always geared to women's needs. The second concerns the social stigma associated with emotional and/or mental disorders and their care while the third involves the characteristics of psychologists and their professional work. In order to overcome some of the barriers identified, users should be given information on the work of mental health professionals, which would help dispel certain misconceptions and sensitize them to the importance of this type of treatment in achieving overall health. There is also a need to make psychologists aware of the living conditions and socio-cultural context of the women who attend these health facilities.

To assess the impact on health care cost and quality among seniors of a patient-centered medical home (PCMH) pilot at Group Health Cooperative, an integrated health care system in Washington State. A prospective before-and-after evaluation of the experience of seniors receiving primary care services at 1 pilot clinic compared with seniors enrolled at the remaining 19 primary care clinics owned and operated by Group Health. Analyses of secondary data on quality and cost were conducted for 1,947 seniors in the PCMH clinic and 39,396 seniors in the 19 control clinics. Patient experience with care was based on survey data collected from 487 seniors in the PCMH clinic and of 668 in 2 specific control clinics that were selected for their similarities in organization and patient composition to the pilot clinic. After adjusting for baseline, seniors in the PCMH clinic reported higher ratings than controls on 3 of 7 patient experience scales. Seniors in the PCMH clinic had significantly greater quality outcomes over time, but this difference was not significant relative to control. PCMH patients used more e-mail, phone, and specialist visits but fewer emergency services and inpatient admissions for ambulatory care sensitive conditions. At 1 and 2 years, the PCMH and control clinics did not differ significantly in overall costs. A PCMH redesign can be associated with improvements in patient experience and quality without increasing overall cost.

Health literacy and communication quality in health care organizations.

Wynia, Matthew K; Osborn, Chandra Y

2010-01-01

The relationship between limited health literacy and poor health may be due, in part, to poor communication quality within health care delivery organizations. We explored the relationship between health literacy status and receiving patient-centered communication in clinics and hospitals serving communication-vulnerable patient populations. Thirteen health care organizations nationwide distributed a survey to 5929 patients. All patients completed seven items assessing patient-centered communication. One third also completed three items assessing health literacy. The majority of patients had self-reported health literacy challenges, reporting problems learning about their medical condition because of difficulty understanding written information (53%), a lack of confidence in completing medical forms by themselves (61%), and needing someone to help them read hospital/clinic materials (57%). Logistic regression models showed that, after adjustment for patient demographic characteristics and health care organization type, patients with limited health literacy were 28% to 79% less likely than those with adequate health literacy to report their health care organization "always" provides patient-centered communication across seven communication items. Using a scaled composite of these items, limited health literacy remained associated with lower reported communication quality. These results suggest that improving communication quality in health care organizations might help to address the challenges facing patients with limited health literacy. They also highlight that efforts to address the needs of patients with limited health literacy should be sensitive to the range of communication challenges confronting these patients and their caregivers.

Different and Similar at the Same Time. Cultural Competence through the Leans of Healthcare Providers.

PubMed

Dell'Aversana, Giuseppina; Bruno, Andreina

2017-01-01

Cultural competence (CC) for professionals and organizations has been recognized as a key strategy to reduce health care inequalities for migrants and to promote responsiveness to diversity. For decades its main aim has been matching health services to the cultural needs of migrant users. Otherwise literature highlighted the need to find a pragmatic middle way between the 'static' and the 'dynamic' views of culture that are recognizable in CC approaches. A pragmatic middle way to CC will be proposed as the way to respect diversity, even responding to cultural issues, without stereotyping or discriminating. To understand conditions that favor this pragmatic middle way this study aims to explore: (1) perceptions of healthcare providers in managing diversity; (2) strategies used to meet health needs at a professional and organizational level. A qualitative case study was conducted in a healthcare service renowned for its engagement in migrant sensitive care. Four different professional figures involved in CC strategies at different levels, both managerial and non-managerial, were interviewed. Data were analyzed using thematic analysis. Findings indicated that dealing with diversity poses challenges for healthcare providers, by confronting them with multilevel barriers to quality of care. A pragmatic middle way to CC seems to rely on complex understanding of the interaction between patients social conditions and the capacity of the institutional system to promote equity. Professional and organizational strategies, such as inter-professional and intersectional collaboration, cultural food adaptation and professional training can enhance quality of care, patient compliance responding to social and cultural needs.

2013-01-01

Rationale Psychostimulant sensitization heightens behavioral and motivational responses to reward-associated stimuli; however, its effects on stimuli associated with reward absence are less understood. Objectives We examined whether amphetamine sensitization alters performance during Pavlovian-instrumental transfer (PIT) to conditioned excitors and inhibitors. We further sought to characterize the effects of amphetamine sensitization on learning versus performance by exposing rats to amphetamine prior to Pavlovian training or between training and test. Methods Adult male Long Evans rats were given conditioned inhibition (A+/AX−) and Pavlovian (B+) training, followed by variable-interval instrumental conditioning. Rats were sensitized to d-amphetamine (2 mg/kg daily injections for seven days), or served as non-exposed controls. Rats were given a PIT test, in which they were presented with stimulus B alone or in compound with the conditioned inhibitor (BX). Results During the PIT test, control rats significantly reduced instrumental responding on BX trials (to approximately 50% of responding to B). Amphetamine sensitization prior to Pavlovian conditioning increased lever-pressing on BX trials and reduced lever-pressing on B trials compared to controls. Amphetamine sensitization between training and test increased lever-pressing on B and BX trials compared to controls. No effects of sensitization were observed on conditioned food-cup approach. Conclusions Amphetamine sensitization increases instrumental responding during PIT to a conditioned inhibitor, by enhancing excitation of conditioned stimuli and reducing inhibition of conditioned inhibitors.

Total Recall: Can We Reshape T Cell Memory by Lymphoablation?

PubMed

Nicosia, M; Valujskikh, A

2017-07-01

Despite recent advances in immunosuppression, donor-reactive memory T cells remain a serious threat to successful organ transplantation. To alleviate damaging effects of preexisting immunologic memory, lymphoablative induction therapies are used as part of standard care in sensitized recipients. However, accumulating evidence suggests that memory T cells have advantages over their naive counterparts in surviving depletion and expanding under lymphopenic conditions. This may at least partially explain the inability of existing lymphoablative strategies to improve long-term allograft outcome in sensitized recipients, despite the well-documented decrease in the frequency of early acute rejection episodes. This minireview summarizes the insights gained from both experimental and clinical transplantation as to the effects of existing lymphoablative strategies on memory T cells and discusses the latest research developments aimed at improving the efficacy and safety of lymphoablation. © 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

A highly sensitive and accurate gene expression analysis by sequencing ("bead-seq") for a single cell.

2015-02-15

Analyses of gene expressions in single cells are important for understanding detailed biological phenomena. Here, a highly sensitive and accurate method by sequencing (called "bead-seq") to obtain a whole gene expression profile for a single cell is proposed. A key feature of the method is to use a complementary DNA (cDNA) library on magnetic beads, which enables adding washing steps to remove residual reagents in a sample preparation process. By adding the washing steps, the next steps can be carried out under the optimal conditions without losing cDNAs. Error sources were carefully evaluated to conclude that the first several steps were the key steps. It is demonstrated that bead-seq is superior to the conventional methods for single-cell gene expression analyses in terms of reproducibility, quantitative accuracy, and biases caused during sample preparation and sequencing processes.

Nurse prescriber-patient consultations: a case study in dermatology.

PubMed

Courtenay, Molly; Carey, Nicola; Stenner, Karen

2009-06-01

This paper is a report of a study exploring the content and processes in consultations between nurse prescribers and patients with dermatological conditions. Communication skills, consultation time, information and follow-up are central to the treatment and management of patients with dermatological conditions. The contribution nurses make to the care of these patients has great potential. A multiple case study was conducted with 10 practice settings across England in which nurses prescribed medicines for patients with dermatological conditions. Data were collected between June 2006 and September 2007 using semi-structured interviews (n = 40), patient questionnaires (n = 165/200) and videotaped observations of nurse consultations (n = 40). Data analysis included thematic analysis, descriptive statistics, chi-square and non-parametric tests. Nurses believed that their holistic approach to assessment, combined with their prescribing knowledge, improved prescribing decisions. Listening and explanation of treatments were aspects of nurse communication that were rated highly by patients. Listening and dealing sensitively with emotions were also aspects of the videotaped consultations that were rated highly by assessors. Nurses were less consistent in providing information about medicines. Triangulated data from this study suggest that nurse prescribing enhances the care of patients with dermatological conditions through improved prescribing decisions. If patients are to be more involved in this decision-making, nurses must give them more information about their medicines. The benefits of prescribing were most evident in the practices of dermatology specialist nurses. Further evidence is required to identify whether prescribing by specialist nurses offers similar benefits in other therapeutic areas.

Hair-care practices in African American women: potential for allergic contact dermatitis.

Stallings, Alicia; Sood, Apra

2016-12-01

Allergic contact dermatitis (ACD) is a delayed hypersensitivity reaction that occurs when the skin is re-exposed to a substance to which it was previously sensitized. One significant source of exposure to sensitizing chemicals is through personal grooming and beauty products. While the role of cosmetics and hair-care products in the development of ACD is well-documented, there has been very little literature that specifically addresses the role of hair-care practices of patients with tightly curled hair, such as in patients of African descent, in the development of ACD in this population. This review provides an integrated summary of the hair-care practices of female African American patients and the potential for exposure to sensitizing agents at each stage. This review will also discuss the challenges faced in recognizing and assessing ACD in these patients. ©2016 Frontline Medical Communications.

Assessing the sensitivity of human skin hyperspectral responses to increasing anemia severity levels

Anemia is a prevalent medical condition that seriously affects millions of people all over the world. In many regions, not only its initial detection but also its monitoring are hindered by limited access to laboratory facilities. This situation has motivated the development of a wide range of optical devices and procedures to assist physicians in these tasks. Although noticeable progress has been achieved in this area, the search for reliable, low-cost, and risk-free solutions still continues, and the strengthening of the knowledge base about this disorder and its effects is essential for the success of these initiatives. We contribute to these efforts by closely examining the sensitivity of human skin hyperspectral responses (within and outside the visible region of the light spectrum) to reduced hemoglobin concentrations associated with increasing anemia severity levels. This investigation, which involves skin specimens with distinct biophysical and morphological characteristics, is supported by controlled in silico experiments performed using a predictive light transport model and measured data reported in the biomedical literature. We also propose a noninvasive procedure to be employed in the monitoring of this condition at the point-of-care.

Determinants of Prosocial Behavior in Included Versus Excluded Contexts

Prosocial behavior (PSB) is increasingly becoming necessary as more and more individuals experience exclusion. In this context it is important to understand the motivational determinants of PSB. Here we report two experiments which analyzed the influence of dispositional (prosocialness; rejection sensitivity) and motivational variables (prosocial self-efficacy; prosocial collective efficacy; trust; anger; social affiliation motivation) on PSB under neutral contexts (Study 1), and once under inclusion or exclusion conditions (Study 2). Both studies provided evidence for the predicted mediation of PSB. Results in both neutral and inclusion and exclusion conditions supported our predictive model of PSB. In the model dispositional variables predicted motivational variables, which in turn predicted PSB. We showed that the investigated variables predicted PSB; this suggests that to promote PSB one could (1) foster prosocialness, prosocial self and collective efficacy, trust in others and affiliation motivation and (2) try to reduce negative feelings and the tendency to dread rejection in an attempt to reduce the negative impact that these variables have on PSB. Moreover, the few differences that emerged in the model between the inclusion and exclusion contexts suggested that in interventions with excluded individuals special care emphasis should be placed on addressing rejection sensitivity and lack of trust.

We demonstrate high-performance wearable electronic-bandage (E-bandage) based on carbon nanotube (CNT)/silver nanoparticle (AgNP) composites covered with flexible media of fluoropolymer-coated polydimethylsiloxane (PDMS) films. The E-bandage can be used for motion-related sensors by directly attaching them to human skin, which achieves a fast and accurate electric response with high sensitivity according to the bending and stretching movements that induce changes in the conductivity. This advance in the E-bandage is realized as a result of the sensitivity that can be achieved by controlling the concentration of AgNPs in CNT pastes and by modifying the device architecture. The fluoropolymer encapsulation with hydrophobic surface characteristics allows for the E-bandage to operate in water and protects it from physical and chemical contact with the daily life conditions of the human skin. The reliability and scalability of the E-bandage as well as the compatibility with conventional microfabrication allow new possibilities to integrate flexible human-interactive nanoelectronics into mobile health-care monitoring systems combined with Internet of things (IoTs).

To develop a sensitive fluorescence polarization immunoassay (FPIA) for screening the zearalenone class of mycotoxins in maize, two new monoclonal antibodies with uniform affinity to the zearalenone class and four fluorescein-labeled tracers were prepared. After careful selection of appropriate tracer-antibody pairs in terms of sensitivity and specificity, a FPIA that could simultaneously detect the zearalenone class with similar sensitivity was developed. Under optimum conditions, the half maximal inhibitory concentrations of the FPIA in buffer were 1.89, 1.97, 2.43, 1.99, 2.27, and 2.44 μg/L for zearalenone, α-zearalenol, β-zearalenol, α-zearalanol, β-zearalanol, and zearalanone, respectively. The limit of detection of FPIA for the zearalenone class was around 12 μg/kg in maize, and the recoveries ranged from 84.6 to 113.8%, with coefficients of variation below 15.3% in spiked samples. Finally, the FPIA was applied for screening naturally contaminated maize samples, and the results indicated a good correlation with that of high-performance liquid chromatography-tandem mass spectrometry.

Community-based surveillance methods to monitor epidemiological progress in surgery have not yet been employed for surgical capacity building. The aim of this study was to create and assess the validity of a questionnaire that collected data for untreated surgically correctable diseases throughout Burera District, northern Rwanda, to accurately plan for surgical services. A structured interview to assess for the presence or absence of ten index surgically treatable conditions (breast mass, cleft lip/palate, club foot, hernia or hydrocele [adult and paediatric]), hydrocephalus, hypospadias, injuries or wounds, neck mass, undescended testes, and vaginal fistula) was created. The interview was built based on previously validated questionnaires, forward and back translated into the local language and underwent focus group augmentation and pilot testing. In March and May, 2012, data collectors conducted the structured interviews with a household representative in 30 villages throughout Burera District, selected using a two-stage cluster sampling design. Rwandan physicians revisited the surveyed households to perform physical examinations on all household members, used as the gold standard to validate the structured interview. Ethical approval was obtained from Boston Children's Hospital (Boston, MA, USA) and the Rwandan National Ethics Committee (Kigali, Rwanda). Informed consent was obtained from all households. 2990 individuals were surveyed, a 97% response rate. 2094 (70%) individuals were available for physical examination. The calculated overall sensitivity of the structured interview tool was 44·5% (95% CI 38·9-50·2) and the specificity was 97·7% (96·9-98·3%; appendix). The positive predictive value was 70% (95% CI 60·5-73·5), whereas the negative predictive value was 91·3% (90·0-92·5). The conditions with the highest sensitivity and specificity, respectively, were hydrocephalus (100% and 100%), clubfoot (100% and 99·8%), injuries or wounds (54·7% and 98·9%), and hypospadias (50% and 100%). Injuries or wounds and hernias or hydroceles were the conditions most frequently identified on examination that were not reported during the interview (appendix). To the best of our knowledge, this study provides the first attempt to validate a community-based surgical surveillance tool. The finding of low sensitivity limits the use of the tool, which will require further revision, and calls into question previously published unvalidated community surgical survey data. To improve validation of community-based surveys, community education efforts on common surgically treatable conditions are needed in conjunction with increased access to surgical care. Accurate community-based surveys are crucial to integrated health system planning that includes surgical care as a core component. The Harvard Sheldon Traveling Fellowship.

Wired for motherhood: induction of maternal care but not maternal aggression in virgin female CD1 mice

Virgin adult female mice display nearly spontaneous maternal care towards foster pups after a short period of sensitization. This indicates that maternal care is triggered by sensory stimulation provided by the pups and that its onset is largely independent on the physiological events related to gestation, parturition and lactation. Conversely, the factors influencing maternal aggression are poorly understood. In this study, we sought to characterize two models of maternal sensitization in the outbred CD1 strain. To do so, a group of virgin females (godmothers) were exposed to continuous cohabitation with a lactating dam and their pups from the moment of parturition, whereas a second group (pup-sensitized females), were exposed 2 h daily to foster pups. Both groups were tested for maternal behavior on postnatal days 2–4. Godmothers expressed full maternal care from the first test. Also, they expressed higher levels of crouching than dams. Pup-sensitized females differed from dams in all measures of pup-directed behavior in the first test, and expressed full maternal care after two sessions of contact with pups. However, both protocols failed to induce maternal aggression toward a male intruder after full onset of pup-directed maternal behavior, even in the presence of pups. Our study confirms that adult female mice need a short sensitization period before the onset of maternal care. Further, it shows that pup-oriented and non-pup-oriented components of maternal behavior are under different physiological control. We conclude that the godmother model might be useful to study the physiological and neural bases of the maternal behavior repertoire. PMID:26257621

Limited research has been conducted to compare the test characteristics of the 1991 and 2001 sepsis consensus definitions. This study assessed the accuracy of the two sepsis consensus definitions among adult critically ill patients compared to sepsis case adjudication by three senior clinicians. Observational study of patients admitted to intensive care units. Seven intensive care units of an academic medical center. A random sample of 960 patients from all adult intensive care unit patients between October 2007 and December 2008. None. Sensitivity, specificity, and the area under the receiver operating characteristic curve for the two consensus definitions were calculated by comparing the number of patients who met or did not meet consensus definitions vs. the number of patients who were or were not diagnosed with sepsis by adjudication. The 1991 sepsis definition had a high sensitivity of 94.6%, but a low specificity of 61.0%. The 2001 sepsis definition had a slightly increased sensitivity but a decreased specificity, which were 96.9% and 58.3%, respectively. The areas under the receiver operating characteristic curve for the two definitions were not statistically different (0.778 and 0.776, respectively). The sensitivities and areas under the receiver operating characteristic curve of both definitions were lower at the 24-hr time window level than those of the intensive care unit stay level, though their specificities increased slightly. Fever, high white blood cell count or immature forms, low Glasgow coma score, edema, positive fluid balance, high cardiac index, low PaO2/FIO2 ratio, and high levels of creatinine and lactate were significantly associated with sepsis by both definitions and adjudication. Both the 1991 and the 2001 sepsis definition have a high sensitivity but low specificity; the 2001 definition has a slightly increased sensitivity but a decreased specificity compared to the 1991 definition. The diagnostic performances of both definitions were suboptimal. A parsimonious set of significant predictors for sepsis diagnosis is likely to improve current sepsis case definitions.

The Impacts of China's Urban Employee Basic Medical Insurance on Healthcare Expenditures and Health Outcomes.

At the end of 1998, China launched a government-run mandatory insurance program, the urban employee basic medical insurance (UEBMI), to replace the previous medical insurance system. Using the UEBMI reform in China as a natural experiment, this study identifies variations in patient cost sharing that were imposed by the UEBMI reform and examines their effects on the demand for healthcare services. Using data from the 1991-2006 waves of the China Health and Nutrition Survey, we find that increased cost sharing is associated with decreased outpatient medical care utilization and expenditures but not with decreased inpatient care utilization and expenditures. Patients from low-income and middle-income households or with less severe medical conditions are more sensitive to prices. We observe little impact on patient's health, as measured by self-reported health status. Copyright © 2015 John Wiley & Sons, Ltd. Copyright © 2015 John Wiley & Sons, Ltd.

The objectives of this article are two-fold: (1) to gather in one place reliable information about Russian-Americans' past medical practices and their current outlook on health care and to provide health care professionals with an overview of the major afflictions suffered by this ethnic group; and (2) to educate Russian-speaking patients about the American heath care system and social services geared towards immigrants by locating and evaluating free, culturally appropriate patient education Web sites available in Russian. In order to draw data on specific diseases and conditions affecting the Russian-speaking population, the author searched various scholarly health-related electronic databases. A number of well-established U.S. government consumer-health Web sites were searched to locate patient education resources that can be utilized by recent Russian immigrants. The author provides an overview of the major health problems encountered by the Russian-speaking population before emigration and potential health concerns for Russian immigrant communities. In addition, the author provides a scholarly exploration of patient education materials available in Russian. In this increasingly diverse society, physicians are faced with the challenge of providing culturally sensitive health care. Multicultural Web-based health resources can serve as a valuable tool for reducing communication barriers between patients and health care providers, thus improving the delivery of quality health care services. Recommendations for further research are indicated. The author offers recommendations for practitioners serving Russian-speaking immigrants. Suggestions on utilization of Web resources are also provided.

Design Document analysis of Australian care plan templates published from 2006 to 2014 that incorporated recommendations for managing comorbid conditions in primary care. Results Sixteen templates were reviewed. All of the care plan templates addressed patient preference, but this was not done comprehensively. Only three templates included setting priorities. None assisted in identifying conflicts and synergies between conditions. Fifteen templates included setting a date for reviewing the care plan. Conclusions Care plans are a well-used tool in primary care practice, but their current format perpetuates a single-disease approach to care, which works contrary to their intended purpose. Restructuring care plans to incorporate shared decision-making and attention to patient preferences may assist in shifting the focus back to the patient and their care needs. PMID:29090181

Sugar reduction in beverages can contribute to reduce consumption of this nutrient and to improve the health status of the population. However, such reduction can negatively affect consumer perception. Label information can be an effective tool to increase consumer interest in sugar-reduced products. In this context, the aim of the present work was to study the influence of health/hedonic claims on consumer hedonic and sensory perception of sugar reduction in orange/passionfruit nectars under expected and informed conditions. Sugar-reduced orange/passionfruit nectars (20% and 40% reduced in added sugar) featuring different claims (none, health claim or hedonic claim) were evaluated, together with a control product without reduction. Following a between-subjects experimental design, 206 participants evaluated the nectars under two experimental conditions: (a) expected, looking at the packages, and (b) informed, looking at the packages and tasting the nectars. In each experimental condition, participants evaluated their overall liking using a 9-point hedonic scale and answered a check-all-that-apply questions related to the sensory characteristics of the nectars. Results showed that although consumers did not have negative expectations about sugar-reduced nectars, the sensory characteristics of the products were the main determinants of consumers' hedonic reaction towards the nectars. The influence of claims on consumers' perception was modulated by their hedonic sensitivity towards sugar-reduction. The hedonic claim increased overall liking of those consumers with low hedonic sensitivity towards sugar reduction, whereas it had the opposite effect on the most sensitive consumers. Results from the present work suggest that although hedonic claims hold potential for a consumer segment, care must be taken to avoid the generation of unrealistic expectations about the sensory characteristics of sugar-reduced products.

Age-related hearing loss: quality of care for quality of life.

PubMed

Li-Korotky, Ha-Sheng

2012-04-01

Age-related hearing loss (ARHL), known as presbycusis, is characterized by progressive deterioration of auditory sensitivity, loss of the auditory sensory cells, and central processing functions associated with the aging process. ARHL is the third most prevalent chronic condition in older Americans, after hypertension and arthritis, and is a leading cause of adult hearing handicaps in the United States. The prevalence of ARHL is expected to rise for the next several decades with the increasing aging Baby Boomer population. Nevertheless, ARHL remains an often undetected, underestimated and neglected condition in the geriatric population due to a slow development process of the disease. If left untreated, the impact of ARHL on patients, significant others, and the society as a whole would be significant. The purpose of this review is to raise the awareness of ARHL, to update our current understanding of ARHL with a focus on age-related deficits in auditory and cognitive processing of speech, and to explore strategies of prevention, identification, amplification, and aural rehabilitation. The ultimate goal is to improve the quality of hearing health care and the overall quality of life of the Baby Boomer generation.

The purpose of this study is to investigate provider specialty, care coordination, and cancer survivors' comorbid condition care. This retrospective cross-sectional Surveillance, Epidemiology, and End Results (SEER)-Medicare study included cancer survivors diagnosed in 2004, 2-3 years post-cancer diagnosis, in fee-for-service Medicare. We examined (1) provider specialties (primary care providers (PCPs), oncology specialists, other specialists) visited post-hospitalization, (2) role of provider specialties in chronic and acute condition management, and (3) an ambulatory care coordination measure. Outcome measures covered (1) visits post-hospitalization for nine conditions, (2) chronic disease management (lipid profile, diabetic eye exam, diabetic monitoring), and (3) acute condition management (electrocardiogram (EKG) for congestive heart failure (CHF), imaging for CHF, EKG for transient ischemic attack, cholecystectomy, hip fracture repair). Among 8661 cancer survivors, patients were more likely to visit PCPs than oncologists or other specialists following hospitalizations for 8/9 conditions. Patients visiting a PCP (vs. not) were more likely to receive recommended care for 3/3 chronic and 1/5 acute condition indicators. Patients visiting a nother specialist (vs. not) were more likely to receive recommended care for 3/3 chronic and 2/5 acute condition indicators. Patients visiting an oncology specialist (vs. not) were more likely to receive recommended care on 2/3 chronic indicators and less likely to receive recommended care on 1/5 acute indicators. Patients at greatest risk for poor coordination were more likely to receive appropriate care on 4/6 indicators. PCPs are central to cancer survivors' non-cancer comorbid condition care quality. Implications for Cancer Survivors PCP involvement in cancer survivors' care should be promoted.

Despite the body of literature on gender dimensions and disparities between the sexes in health, practical improvements will not be realized effectively as long as we lack an overview of the ways how to implement these ideas. This systematic review provides a content analysis of literature on the implementation of gender sensitivity in health care. Literature was identified from CINAHL, PsycINFO, Medline, EBSCO and Cochrane (1998-2008) and the reference lists of relevant articles. The quality and relevance of 752 articles were assessed and finally 11 original studies were included. Our results demonstrate that the implementation of gender sensitivity includes tailoring opportunities and barriers related to the professional, organizational and the policy level. As gender disparities are embedded in healthcare, a multiple track approach to implement gender sensitivity is needed to change gendered healthcare systems. Conventional approaches, taking into account one barrier and/or opportunity, fail to prevent gender inequality in health care. For gender-sensitive health care we need to change systems and structures, but also to enhance understanding, raise awareness and develop skills among health professionals. To bring gender sensitivity into healthcare practice, interventions should address a range of factors. Copyright © 2010. Published by Elsevier Ireland Ltd.

Spatial analysis of elderly access to primary care services.

2006-05-15

Admissions for Ambulatory Care Sensitive Conditions (ACSCs) are considered preventable admissions, because they are unlikely to occur when good preventive health care is received. Thus, high rates of admissions for ACSCs among the elderly (persons aged 65 or above who qualify for Medicare health insurance) are signals of poor preventive care utilization. The relevant geographic market to use in studying these admission rates is the primary care physician market. Our conceptual model assumes that local market conditions serving as interventions along the pathways to preventive care services utilization can impact ACSC admission rates. We examine the relationships between market-level supply and demand factors on market-level rates of ACSC admissions among the elderly residing in the U.S. in the late 1990s. Using 6,475 natural markets in the mainland U.S. defined by The Health Resources and Services Administration's Primary Care Service Area Project, spatial regression is used to estimate the model, controlling for disease severity using detailed information from Medicare claims files. Our evidence suggests that elderly living in impoverished rural areas or in sprawling suburban places are about equally more likely to be admitted for ACSCs. Greater availability of physicians does not seem to matter, but greater prevalence of non-physician clinicians and international medical graduates, relative to U.S. medical graduates, does seem to reduce ACSC admissions, especially in poor rural areas. The relative importance of non-physician clinicians and international medical graduates in providing primary care to the elderly in geographic areas of greatest need can inform the ongoing debate regarding whether there is an impending shortage of physicians in the United States. These findings support other authors who claim that the existing supply of physicians is perhaps adequate, however the distribution of them across the landscape may not be optimal. The finding that elderly who reside in sprawling urban areas have access impediments about equal to residents of poor rural communities is new, and demonstrates the value of conceptualizing and modelling impedance based on place and local context.

The objective of this study is to investigate the factors associated with depressive symptoms and chronic illnesses in American Indians compared with White adults born in the post-World War II period, 1946 to 1964, and living in South Dakota. A cross-sectional design of American Indian and White adults aged 50 and older in South Dakota (Brookings, Vermillion, Sioux Falls, and all others areas of South Dakota) between January 2013 and May 2013 was used. American Indian and White adults (born between 1946 and 1964; N = 349). Data included sociodemographic factors and measures of chronic physical health condition, health care access, adverse childhood experiences, body mass index (BMI), Alcohol Use Disorders Identification Test, Technology Acceptance Model, and Multidimensional Scale of Perceived Social Support and Depressive Symptoms. American Indian adults reported more chronic diseases and conditions, a lower self-perceived physical health, were more likely to be overweight or obese, had more adverse childhood experience (ACE), and reported a lower level of alcohol intake compared to White adults. BMI was significantly associated with an increased number of chronic conditions for both groups, and American Indians' better perception of their physical health was significantly associated with lower total number of chronic conditions. Self-perceived mental health, a better level of access to health care, and a higher degree of social support were significantly inversely associated with the number of depressive symptoms for American Indian adults, while a greater level of ACE was significantly associated with an increased number of depressive symptoms for this group. The current study not only support previous studies but also contributes to understanding the disparities in and risk factors potentially impacting American Indians' physical and mental health. Our findings highlight the need to investigate the American Indians' perceptions and knowledge about health care accessibility including availability as well as perceived barriers including social sensitivity and trust. Health professionals might need to pay attention to BMI, ACE, and social relationship among American Indian adults to improve physical and mental health.

Continuous EEG screening using spectrograms or compressed spectral arrays (CSAs) by neurophysiologists has shorter review times with minimal loss of sensitivity for seizure detection when compared with visual analysis of raw EEG. Limited data are available on the performance characteristics of CSA-based seizure detection by neurocritical care nurses. This is a prospective cross-sectional study that was conducted in two academic neurocritical care units and involved 33 neurointensive care unit nurses and four neurophysiologists. All nurses underwent a brief training session before testing. Forty two-hour CSA segments of continuous EEG were reviewed and rated for the presence of seizures. Two experienced clinical neurophysiologists masked to the CSA data performed conventional visual analysis of the raw EEG and served as the gold standard. The overall accuracy was 55.7% among nurses and 67.5% among neurophysiologists. Nurse seizure detection sensitivity was 73.8%, and the false-positive rate was 1-per-3.2 hours. Sensitivity and false-alarm rate for the neurophysiologists was 66.3% and 1-per-6.4 hours, respectively. Interrater agreement for seizure screening was fair for nurses (Gwet AC1 statistic: 43.4%) and neurophysiologists (AC1: 46.3%). Training nurses to perform seizure screening utilizing continuous EEG CSA displays is feasible and associated with moderate sensitivity. Nurses and neurophysiologists had comparable sensitivities, but nurses had a higher false-positive rate. Further work is needed to improve sensitivity and reduce false-alarm rates.

We developed a discrete-event simulation model of patient pathway through an acute care hospital that comprises an ED and several inpatient units. The effects of discharge timing on ED waiting and boarding times, ambulance diversions, leave without treatment, and readmissions were explicitly modeled. We then analyzed the impact of 1 static and 2 proactive discharge strategies on these system outcomes. Our analysis indicated that although the 2 proactive discharge strategies significantly reduced ED waiting and boarding times, and several other measures, compared with the static strategy (P < 0.01), the number of readmissions increased substantially. Further analysis indicated that these findings are sensitive to changes in patient arrival rate and conditions for ambulance diversion. Determining the appropriate time to discharge patients not only can affect individual patients' health outcomes, but also can affect various aspects of the hospital. The study improves our understanding of how individual inpatient discharge decisions can be objectively viewed in terms of their impact on other operations, such as ED crowding and readmission, in an acute care hospital.

Preventive Health Care for Women Who Have Sex with Women.

PubMed

Knight, Daniel A; Jarrett, Diane

2017-03-01

Despite recent shifts in societal attitudes toward same-sex relationships, women who have sex with women face a variety of barriers to optimal health, including a history of negatively perceived interactions in clinical settings that lead them to delay or avoid health care. Women who have sex with women may be at disproportionate risk of obesity, tobacco use, substance use, mental health issues, intimate partner violence, sexually transmitted infections, and some cancers. Disparities can exist throughout the lifetime. Lesbian and bisexual adolescents are vulnerable to bullying, family rejection, and risky sexual behavior that may lead to sexually transmitted infections or unintended pregnancy. Sexual minority stress, which is a response to stigmatization, prejudice, and internalized homophobia, contributes to many of these conditions. Family physicians should foster trust and communication to provide a nonjudgmental, welcoming environment supportive of culturally competent health care and optimal outcomes. When indicated, clinicians should refer women who have sex with women to culturally sensitive community resources and legal advisors for assistance with medical decision making, hospital visitation, conception, and legal recognition of nonbiologic parents.

American Indians/Alaska Natives (AIs/ANs) have higher rates of chronic illness and lack access to palliative/end-of-life (EOL) care. This integrative review ascertained the state of the science on culturally acceptable palliative/EOL care options for Indigenous persons in the United States. Databases searched: CINAHL, PubMed/MEDLINE, SocINDEX, PsycINFO, PsycARTICLES, ERIC, Health Source: Nursing/Academic Edition, and EBSCO Discovery Service 1880s-Present. Key terms used: palliative care, EOL care, and AI/AN. peer-reviewed articles published in English. Findings/Results: Twenty-nine articles were identified, 17 remained that described culturally specific palliative/EOL care for AIs/ANs. Synthesis revealed four themes: Communication, Cultural Awareness/Sensitivity, Community Guidance for Palliative/EOL Care Programs, Barriers and two subthemes: Trust/Respect and Mistrust. Limitations are lack of research funding, geographic isolation, and stringent government requirements. Palliative/EOL care must draw on a different set of skills that honor care beyond cure provided in a culturally sensitive manner.

Economic burden of chronic conditions among households in Myanmar: the case of angina and asthma.

Non-communicable diseases (NCDs) are becoming a major source of the national disease burden in Myanmar with potentially serious economic implications. Using data on 5484 households from the World Health Survey (WHS), this study assessed the household-level economic burden of two chronic conditions, angina and asthma, in Myanmar. Propensity score matching (PSM) and coarsened exact matching (CEM) methods were used to compare household out-of-pocket (OOP) spending, catastrophic and impoverishment effects, reliance on borrowing or asset sales to finance OOP healthcare payments and employment among households reporting a member with angina (asthma) to matched households, with and without adjusting for comorbidities. Sensitivity analyses were carried out to assess the impacts of alternative assumptions on common support and potential violations of the assumption of independence of households being angina (asthma) affected and household economic outcomes, conditional on the variables used for matching (conditional independence). Households with angina (asthma) reported greater OOP spending (angina: range I$1.94-I$4.31; asthma: range I$1.53-I$2.01) (I$1 = 125.09 Myanmar Kyats; I$=International Dollar) almost half of which was spending on medicines; higher rates of catastrophic spending based on a 20% threshold ratio of OOP to total household spending (angina: range 6-7%; asthma: range 3-5%); greater reliance on borrowing and sale of assets to finance healthcare (angina: range 12-14%; asthma: range 40-49%); increased medical impoverishment and lower employment rates than matched controls. There were no statistically differences in OOP expenses for inpatient care between angina-affected (asthma-affected) households and matched controls. Our results were generally robust to multiple methods of matching. However, conclusions for medical impoverishment impacts were not robust to potential violations of the conditional independence assumption. Myanmar is expanding public spending on health and has recently launched an innovative programme for supporting hospital-based care for poor households. Our findings suggest the need for interventions to address OOP expenses associated with outpatient care (including drugs) for chronic conditions in Myanmar's population.

In Western countries, health and social welfare facilities are not easily accessible for elderly immigrants and their needs are sub optimally addressed. A transition is needed towards culturally sensitive services to make cure and care accessible for elderly immigrants. We developed an intervention programme in which ethnic community health workers (CHWs) act as liaisons between immigrant elderly and local health care and social welfare services. In a quasi experimental design, the effectiveness of introduction of CHWs, will be evaluated in three (semi) urban residential areas in the Netherlands within three different migrant groups and compared with a control group. The primary outcome is use of health care and social welfare facilities by the elderly. Secondary outcomes are quality of life and functional impairments. Implementation of the intervention programme will be examined with focus groups and data registration of CHW activities. In this paper design and methodological issues are discussed. This study can contribute to the improvement of care for elderly immigrants by developing culturally sensitive care whereby the elderly immigrants themselves actively participate. To enable a successful transition, proper identification and recruitment of CHWs is required. Once proven effective, the CHW function can be further integrated into the existing local health care and welfare system.

Mode of Effective Connectivity within a Putative Neural Network Differentiates Moral Cognitions Related to Care and Justice Ethics

Background Moral sensitivity refers to the interpretive awareness of moral conflict and can be justice or care oriented. Justice ethics is associated primarily with human rights and the application of moral rules, whereas care ethics is related to human needs and a situational approach involving social emotions. Among the core brain regions involved in moral issue processing are: medial prefrontal cortex, anterior (ACC) and posterior (PCC) cingulate cortex, posterior superior temporal sulcus (pSTS), insula and amygdala. This study sought to inform the long standing debate of whether care and justice moral ethics represent one or two different forms of cognition. Methodology/Principal Findings Model-free and model-based connectivity analysis were used to identify functional neural networks underlying care and justice ethics for a moral sensitivity task. In addition to modest differences in patterns of associated neural activity, distinct modes of functional and effective connectivity were observed for moral sensitivity for care and justice issues that were modulated by individual variation in moral ability. Conclusions/Significance These results support a neurobiological differentiation between care and justice ethics and suggest that human moral behavior reflects the outcome of integrating opposing rule-based, self-other perspectives, and emotional responses.

Health care facilities in low- and middle-income countries are high-risk settings, and face special challenges to achieving sustainable water, sanitation, and hygiene (WASH) services. Our applied interdisciplinary research conducted in India and Uganda analyzed six dimensions of WASH services in selected health care facilities, including menstrual hygiene management. To be effective, WASH monitoring strategies in health care facilities must include gender sensitive measures. We present a novel strategy, showing that applied gender sensitive multitool assessments are highly productive in assessments of WASH services and facilities from user and provider perspectives. We discuss its potential for applications at scale and as an area of future research.

To examine the ability of existing triggers for intensive care unit (ICU) palliative care consultation to predict 6-month mortality, and derive new triggers for consultation based on risk factors for 6-month mortality. Retrospective cohort study of NY state residents who received intensive care, 2008-2013. We examined sensitivity and specificity of existing triggers for predicting 6-month mortality and used logistic regression to generate patient subgroups at high-risk for 6-month mortality as potential novel triggers for ICU palliative care consultation. Of 1,019,849 patients, 195,847 (19.2%) died within 6 months of admission. Existing triggers were specific but not sensitive for predicting 6-month mortality, (sensitivity 0.3%-11.1%, specificity 96.5-99.9% for individual triggers). Using logistic regression, patient subgroups with the highest predicted probability of 6-month mortality were older patients admitted with sepsis (age 70-79 probability 49.7%, [49.5-50.0]) or cancer (non-metastatic cancer, age 70-79 probability 51.5%, [51.1-51.9]; metastatic cancer, age 70-79 probability 60.3%, [59.9-60.6]). Sensitivity and specificity of novel triggers ranged from 0.05% to 9.2% and 98.6% to 99.9%, respectively. Existing triggers for palliative care consultation are specific, but insensitive for 6-month mortality. Using a data-driven approach to derive novel triggers may identify subgroups of patients at high-risk of 6-month mortality. Copyright © 2018 Elsevier Inc. All rights reserved.

The recent wave of migration from Middle Eastern countries to Europe presents significant challenges to the European health profession. These include the inevitable communication gap created by differences in health care beliefs between European oncologists, health care practitioners, and refugee patients. This article presents the conclusions of a workshop attended by a group of clinicians and researchers affiliated with the Middle East Cancer Consortium, as well as four European-based health-related organizations. Workshop participants included leading clinicians and medical educators from the field of integrative medicine and supportive cancer care from Italy, Germany, Turkey, Israel, Palestine, Iran, Lebanon, Jordan, Egypt, and Sudan. The workshop illustrated the need for creating a dialogue between European health care professionals and the refugee population in order to overcome the communication barriers to create healing process. The affinity for complementary and traditional medicine (CTM) among many refugee populations was also addressed, directing participants to the mediating role that integrative medicine serves between CTM and conventional medicine health belief models. This is especially relevant to the use of herbal medicine among oncology patients, for whom an open and nonjudgmental (yet evidence-based) dialogue is of utmost importance. The workshop concluded with a recommendation for the creation of a comprehensive health care model, to include bio-psycho-social and cultural-spiritual elements, addressing both acute and chronic medical conditions. These models need to be codesigned by European and Middle Eastern clinicians and researchers, internalizing a culturally sensitive approach and ethical commitment to the refugee population, as well as indigenous groups originating from Middle Eastern and north African countries. European oncologists face a communication gap with refugee patients who have recently immigrated from Middle Eastern and northern African countries, with their different health belief models and affinity for traditional and herbal medicine. A culturally sensitive approach to care will foster doctor-refugee communication, through the integration of evidence-based medicine within a nonjudgmental, bio-psycho-social-cultural-spiritual agenda, addressing patients' expectation within a supportive and palliative care context. Integrative physicians, who are conventional doctors trained in traditional/complementary medicine, can mediate between conventional and traditional/herbal paradigms of care, facilitating doctor-patient communication through education and by providing clinical consultations within conventional oncology centers. © AlphaMed Press 2017.

Predicting prolonged length of hospital stay in older emergency department users: use of a novel analysis method, the Artificial Neural Network.

To examine performance criteria (i.e., sensitivity, specificity, positive predictive value [PPV], negative predictive value [NPV], likelihood ratios [LR], area under receiver operating characteristic curve [AUROC]) of a 10-item brief geriatric assessment (BGA) for the prediction of prolonged length hospital stay (LHS) in older patients hospitalized in acute care wards after an emergency department (ED) visit, using artificial neural networks (ANNs); and to describe the contribution of each BGA item to the predictive accuracy using the AUROC value. A total of 993 geriatric ED users admitted to acute care wards were included in this prospective cohort study. Age >85years, gender male, polypharmacy, non use of formal and/or informal home-help services, history of falls, temporal disorientation, place of living, reasons and nature for ED admission, and use of psychoactive drugs composed the 10 items of BGA and were recorded at the ED admission. The prolonged LHS was defined as the top third of LHS. The ANNs were conducted using two feeds forward (multilayer perceptron [MLP] and modified MLP). The best performance was reported with the modified MLP involving the 10 items (sensitivity=62.7%; specificity=96.6%; PPV=87.1; NPV=87.5; positive LR=18.2; AUC=90.5). In this model, presence of chronic conditions had the highest contributions (51.3%) in AUROC value. The 10-item BGA appears to accurately predict prolonged LHS, using the ANN MLP method, showing the best criteria performance ever reported until now. Presence of chronic conditions was the main contributor for the predictive accuracy. Copyright © 2015 European Federation of Internal Medicine. Published by Elsevier B.V. All rights reserved.

Time-Dependent Effects of Prazosin on the Development of Methamphetamine Conditioned Hyperactivity and Context-Specific Sensitization in Mice

White, André O.; Rauhut, Anthony S.

2014-01-01

The present experiments examined the effects of prazosin, a selective α1-adrenergic receptor antagonist, on the development of methamphetamine conditioned hyperactivity and context-specific sensitization. Mice received an injection of vehicle (distilled water) or prazosin (0.5, 1.0 or 2.0 mg/kg) 30 minutes prior to a second injection of vehicle (saline) or methamphetamine (1.0 mg/kg) during the conditioning sessions (Experiment 1). Following the conditioning sessions, mice were tested for conditioned hyperactivity and then tested for context-specific sensitization. In subsequent experiments, mice received an injection of vehicle (distilled water) or prazosin (2.0 mg/kg) immediately (Experiment 2) or 24 hours (Experiment 3) after the conditioning sessions and then tested for conditioned hyperactivity and context-specific sensitization. Prazosin dose-dependently blocked the development of methamphetamine conditioned hyperactivity and context-specific sensitization when administered prior to the methamphetamine during the conditioning phase; however nonspecific motor impairments also were observed (Experiment 1). Immediate (Experiment 2), but not the 24-hour delay (Experiment 3), post-session administration of prazosin attenuated the development of methamphetamine conditioned hyperactivity and context-specific sensitization. Nonspecific motor impairments were not observed in these latter experiments. Collectively, these results suggest that the α1-adrenergic receptor mediates the development of methamphetamine-conditioned hyperactivity and context-specific sensitization, perhaps by altering memory consolidation and/or reconsolidation processes.

We examined the sensitivity and specificity of an obesity diagnosis in a nationally representative sample of pediatric outpatient visits. We used the 2005 to 2009 National Ambulatory Medical Care and National Hospital Ambulatory Medical Care surveys. We included visits with children 2 to 18 years, yielding a sample of 48 145 database visits. We determined 3 methods of identifying obesity: documented body mass index (BMI) ≥95th percentile; International Classification of Diseases, Ninth Revision (ICD-9) code; and positive answer to the question, "Does the patient now have obesity?" Using BMI as the gold standard, we calculated the sensitivity and specificity of a clinical obesity diagnosis. Among the 19.5% of children who were obese by BMI, 7.0% had an ICD-9 code and 15.2% had a positive response to questioning. The sensitivity of an obesity diagnosis was 15.4%, and the specificity was 99.2%. The sensitivity of the obesity diagnosis in pediatric ambulatory visits is low. Efforts are needed to increase identification of obese children.

Lipase or amylase for the diagnosis of acute pancreatitis?

PubMed

Ismail, Ola Z; Bhayana, Vipin

2017-12-01

Acute pancreatitis is a rapid onset of inflammation of the pancreas causing mild to severe life threatening conditions [1, 2]. In Canada, acute pancreatitis is the 5th most expensive digestive disease in Canada with a considerable economic burden on the health care system [3]. The diagnosis of acute pancreatitis is usually based on the presence of abdominal pain and elevated levels of serum amylase and/or lipase. Many health care centers use either serum amylase, lipase or both to diagnose acute pancreatitis without considering which one could provide a better diagnostic accuracy. The aim of this review is to investigate whether serum lipase alone is a sufficient biomarker for the diagnosis of acute pancreatitis. We have examined various studies looking at the utilization, sensitivity, specificity and cost associated savings of lipase and amylase in the diagnosis of acute pancreatitis. When comparing different studies, serum lipase offers a higher sensitivity than serum amylase in diagnosing acute pancreatitis. Lipase also offers a larger diagnostic window than amylase since it is elevated for a longer time, thus allowing it to be a useful diagnostic biomarker in early and late stages of acute pancreatitis. Several recent evidence-based guidelines recommend the use of lipase over amylase. Nevertheless, both lipase and amylase alone lack the ability to determine the severity and etiology of acute pancreatitis. The co-ordering of both tests has shown little to no increase in the diagnostic sensitivity and specificity. Thus, unnecessary testing and laboratory expenditures can be reduced by testing lipase alone. Copyright © 2017 The Canadian Society of Clinical Chemists. Published by Elsevier Inc.

Yunus, Muhammad B

2015-01-01

Central sensitization (CS), simply defined as an amplified response of the central nervous system to peripheral input, is a concept of great importance in clinical medicine. It has helped to explain aspects of the pathophysiology of common diseases, e.g. fibromyalgia syndrome (FMS), irritable bowel syndrome, vulvodynia, headaches, chronic pelvic pain and other overlapping conditions (collectively called central sensitivity syndromes, or CSS). It also applies to pain of complex regional pain syndrome, osteoarthritis (OA), rheumatoid arthritis (RA) and post-operative pain. The pathology-pain gap in CSS is readily explained by CS. Many FMS and other CSS patients have peripheral pathology, e.g. nociceptive areas in the muscles, arthritis, small fiber neuropathy and inflammation. Pro-inflammatory cytokines are elevated in some patients. Identification of CS in patients with structural pathology, e.g. OA and RA, has helped to explain why not all patients benefit from nonsteroidal anti-inflammatory drugs or joint replacement surgery, and require therapy directed at CS. Glial cells are important in pain processing. Remarkable advances have been achieved in neuroimaging, including visualization of grey matter and white matter, not only during provoked pain but also pain at rest. Based on CS mechanisms, targeted individual therapy may now be possible. Appropriate nosology is important particularly for effective patient care. Dichotomy of neurochemical-structural ("functional") and structural ("organic") pathology should be abandoned; many patients have both. Psychobiology is also biology. Patient-blaming terms like somatization, somatizer and catastrophizing should be avoided. For therapy, both pharmacological and non- pharmacological approaches are important, including recognition of subgroups and person/patient-centered care.

Laboratory diagnosis of Chlamydia pneumoniae infections

Chlamydia pneumoniae is an important cause of respiratory illness. There is a need for accurate and rapid laboratory diagnostic methods that will lead to improved patient care, appropriate use of antimicrobial therapy and a better understanding of the epidemiology of this emerging pathogen. Culture is highly specific but is technically demanding, expensive, has a long turnaround time and its sensitivity is highly dependent on transport conditions. Antigen detection tests such as enzyme immunoassay and direct fluorescent antibody assay, and molecular detection methods such as the polymerase chain reaction assay, may provide a rapid diagnosis without the requirement for stringent transport conditions. The results of these tests should be interpreted with caution until more thorough evaluation is available. Serology remains the method of choice. The limitations of different serological methods for the laboratory diagnosis of C pneumoniae are discussed. PMID:22514397

Introduction Home-based telebehavioural healthcare improves access to mental health care for patients restricted by travel burden. However, there is limited evidence assessing the economic value of home-based telebehavioural health care compared to in-person care. We sought to compare the economic impact of home-based telebehavioural health care and in-person care for depression among current and former US service members. Methods We performed trial-based cost-minimisation and cost-utility analyses to assess the economic impact of home-based telebehavioural health care versus in-person behavioural care for depression. Our analyses focused on the payer perspective (Department of Defense and Department of Veterans Affairs) at three months. We also performed a scenario analysis where all patients possessed video-conferencing technology that was approved by these agencies. The cost-utility analysis evaluated the impact of different depression categories on the incremental cost-effectiveness ratio. One-way and probabilistic sensitivity analyses were performed to test the robustness of the model assumptions. Results In the base case analysis the total direct cost of home-based telebehavioural health care was higher than in-person care (US$71,974 versus US$20,322). Assuming that patients possessed government-approved video-conferencing technology, home-based telebehavioural health care was less costly compared to in-person care (US$19,177 versus US$20,322). In one-way sensitivity analyses, the proportion of patients possessing personal computers was a major driver of direct costs. In the cost-utility analysis, home-based telebehavioural health care was dominant when patients possessed video-conferencing technology. Results from probabilistic sensitivity analyses did not differ substantially from base case results. Discussion Home-based telebehavioural health care is dependent on the cost of supplying video-conferencing technology to patients but offers the opportunity to increase access to care. Health-care policies centred on implementation of home-based telebehavioural health care should ensure that these technologies are able to be successfully deployed on patients' existing technology.

There is a need for research to facilitate the widespread implementation, dissemination and sustained utilization of evidence-based primary care screening, monitoring and care coordination guidelines, thereby increasing the impact of dental hygienists' actions on patients' oral and general health. The aims of this formative study are to explore dental hygienists' and dentists' perspectives regarding the integration of primary care activities into routine dental care, and assess the needs of dental hygienists and dentists regarding primary care coordination activities and use of information technology to obtain clinical information at chairside. This qualitative study recruited 10 dental hygienists and 6 dentists from 10 New York City area dental offices with diverse patient mixes and volumes. A New York University faculty dental hygienist conducted semi-structured, in-depth interviews, which were digitally recorded and transcribed verbatim. Data analysis consisted of multilevel coding based on the Consolidated Framework for Implementation Research, resulting in emergent themes with accompanying categories. The dental hygienists and dentists interviewed as part of this study do not use evidence-based guidelines to screen their patients for primary care sensitive conditions. Overwhelmingly, dental providers believe that tobacco use and poor diet contribute to oral disease, and report using electronic devices at chairside to obtain web-based health information. Dental hygienists are well positioned to help facilitate greater integration of oral and general health care. Challenges include lack of evidence-based knowledge, coordination between dental hygienists and dentists, and systems-level support, with opportunities for improvement based upon a theory-driven framework.

1999-01-01

A prediction sensitivity assessment to inputs and blade modeling is presented for the TiltRotor Aeroacoustic Code (TRAC). For this study, the non-CFD prediction system option in TRAC is used. Here, the comprehensive rotorcraft code, CAMRAD.Mod1, coupled with the high-resolution sectional loads code HIRES, predicts unsteady blade loads to be used in the noise prediction code WOPWOP. The sensitivity of the predicted blade motions, blade airloads, wake geometry, and acoustics is examined with respect to rotor rpm, blade twist and chord, and to blade dynamic modeling. To accomplish this assessment, an interim input-deck for the TRAM test model and an input-deck for a reference test model are utilized in both rigid and elastic modes. Both of these test models are regarded as near scale models of the V-22 proprotor (tiltrotor). With basic TRAC sensitivities established, initial TRAC predictions are compared to results of an extensive test of an isolated model proprotor. The test was that of the TiltRotor Aeroacoustic Model (TRAM) conducted in the Duits-Nederlandse Windtunnel (DNW). Predictions are compared to measured noise for the proprotor operating over an extensive range of conditions. The variation of predictions demonstrates the great care that must be taken in defining the blade motion. However, even with this variability, the predictions using the different blade modeling successfully capture (bracket) the levels and trends of the noise for conditions ranging from descent to ascent.

Aim The purpose of this study was to investigate the effects of implementing elements of a context-adapted chronic disease-care model (CACCM) in two local government primary healthcare units of a non-highly urbanized city and a rural municipality in the Philippines on Patients' Assessment of Chronic Illness Care (PACIC) and glycaemic control (HbA1c) of people with diabetes. Low-to-middle income countries like the Philippines are beset with rising prevalence of chronic conditions but their healthcare systems are still acute disease oriented. Attention towards improving care for chronic conditions particularly in primary healthcare is imperative and ways by which this can be done amidst resource constraints need to be explored. A chronic care model was adapted based on the context of the Philippines. Selected elements (community sensitization, decision support, minor re-organization of health services, health service delivery-system re-design, and self-management education and support) were implemented. PACIC and HbA1c were measured before and one year after the start of implementation. Findings The improvements in the PACIC (median, from 3.2 to 3.5) as well as in four of the five subsets of the PACIC were statistically significant (P-values: PACIC=0.009; 'patient activation'=0.026; 'goal setting'=0.017; 'problem solving'<0.001; 'follow-up'<0.001). The decrease in HbA1c (median, from 7.7% to 6.9%) and the level of diabetes control of the project participants (increase of optimally controlled diabetes from 37.2% to 50.6%) were likewise significant (P<0.000 and P=0.014). A significantly higher rating of the post-implementation PACIC subsets 'problem solving' (P=0.027) and 'follow-up' (P=0.025) was noted among those participants whose HbA1c improved. The quality of chronic care in general and primary diabetes care in particular may be improved, as measured through the PACIC and glycaemic control, in resource-constrained settings applying selected elements of a CACCM and without causing much strain on an already-burdened healthcare system.

Administrative health care data are frequently used to study disease burden and treatment outcomes in many conditions including osteoarthritis (OA). OA is a chronic condition with significant disease burden affecting over 27 million adults in the US. There are few studies examining the performance of administrative data algorithms to diagnose OA. The purpose of this study is to perform a systematic review of administrative data algorithms for OA diagnosis; and, to evaluate the diagnostic characteristics of algorithms based on restrictiveness and reference standards. Two reviewers independently screened English-language articles published in Medline, Embase, PubMed, and Cochrane databases that used administrative data to identify OA cases. Each algorithm was classified as restrictive or less restrictive based on number and type of administrative codes required to satisfy the case definition. We recorded sensitivity and specificity of algorithms and calculated positive likelihood ratio (LR+) and positive predictive value (PPV) based on assumed OA prevalence of 0.1, 0.25, and 0.50. The search identified 7 studies that used 13 algorithms. Of these 13 algorithms, 5 were classified as restrictive and 8 as less restrictive. Restrictive algorithms had lower median sensitivity and higher median specificity compared to less restrictive algorithms when reference standards were self-report and American college of Rheumatology (ACR) criteria. The algorithms compared to reference standard of physician diagnosis had higher sensitivity and specificity than those compared to self-reported diagnosis or ACR criteria. Restrictive algorithms are more specific for OA diagnosis and can be used to identify cases when false positives have higher costs e.g. interventional studies. Less restrictive algorithms are more sensitive and suited for studies that attempt to identify all cases e.g. screening programs.

Cross-sectional survey. To describe the care received, care needs and preventability of secondary conditions according to persons with long-term spinal cord injury (SCI) living at home. The Netherlands. A questionnaire was sent to all members of the Dutch SCI Patient Organisation. From a list of 26 SCI secondary conditions, participants chose the five conditions they perceived as most important. For each of these conditions, they described the type of care they received, their need for (extra) care and its preventability. Response rate was 45% (n=453) and mean time after injury was 13.3 years. In case of secondary conditions, participants were more likely to visit their general practitioner (58%) than another medical specialist (29%) or rehabilitation specialist (25%). For all most-important secondary conditions, care was received in 47% and care, or extra care, was needed in 41.3%. Treatment was the type of care most often received (29.5%) and needed (17.2%). However, for information and psychosocial care, the care needed (12.2 and 9.9%, respectively) was higher than the care received (7.6 and 5.9%, respectively). Thirty-four percent of all most-important secondary conditions were perceived as preventable, the rate increasing to 52.8% for pressure sores, of which 29.9% were considered to be preventable by the participants themselves. This study showed substantial unmet care needs in persons with long-term SCI living at home and underlines the further improvement of long-term care for this group. Information, psychosocial care and self-efficacy seem to be the areas to be enhanced.

To identify home-based palliative care service utilisation by people with cancer and non-cancer conditions. Palliative care knowledge and skill have been derived from working with people with cancer. People with chronic conditions are now referred for home-based palliative care; however, there has been few studies published that have explored the impact of service utilisation by people with end-stage chronic conditions. The Australia-modified Karnofsky Performance Status (AKPS) scale was calculated for each person upon referral for home-based palliative care services to determine the functional capacity of the individual at the point of referral. Clients were divided into those with cancer diagnosis and those with non-cancer diagnosis. Service utilisation of the individual client was determined until separation from the palliative care service. The study was undertaken in 2007. The majority of people with cancer (63%) and non-cancer (71%) were assessed as having an AKPS score between 50-60. Thirty-one cancer clients (18·7%) and three non-cancer clients (7·1%) had an AKPS score between 70-90. This suggests that people with cancer are referred to palliative care services earlier than people with non-cancer conditions. People with non-cancer conditions were substantially higher users of home-based palliative care services over a longer period of time. Home-based palliative care service utilisation was higher for people with non-cancer conditions. Cost analysis research is recommended to delineate the actual costs of home-based palliative care service provision between people with cancer and non-cancer conditions. There is growing awareness of the need for palliative care services for people with non-cancer conditions. However, these services are provided for longer periods of time for this client group. Implications for practice are that the palliative care needs of people with non-cancer conditions may not be met within current palliative care service provision. There may be funding implications for home-based palliative care services that intend to meet the needs of people at end of life with non-cancer conditions. © 2008 The Authors.

Reversal of apomorphine locomotor sensitization by a single post-conditioning trial treatment with a low autoreceptor dose of apomorphine: a memory re-consolidation approach.

Sensitization is a common feature of psychostimulants and sensitization effects are generally considered to be linked to the addictive properties of these drugs. We used a conventional paired/unpaired Pavlovian protocol to induce a context specific sensitization to the locomotor stimulant effect of a high dose of apomorphine (2.0mg/kg). Two days following a 5 session sensitization induction phase, a brief 5min non-drug test for conditioning was conducted. Only the paired groups exhibited locomotor stimulant conditioned response effects. Immediately following this brief test for conditioning, the paired and the unpaired groups received injections of 0.05mg/kg apomorphine, 2.0mg/kg apomorphine or vehicle designed to differentially impact memory re-consolidation of the conditioning. Two days later, all groups received a sensitization challenge test with 2.0mg/kg apomorphine. The 2.0mg/kg apomorphine post-trial treatment potentiated sensitization while the 0.05mg/kg eliminated sensitization. These effects were only observed in the paired groups. The activation of dopaminergic systems by the high dose of apomorphine strengthened the drug/environment association whereas the inhibition of dopamine activity by the low auto-receptor dose eliminated this association. The results point to the importance of conditioning to context specific sensitization and targeting memory re-consolidation of conditioning as a paradigm to modify sensitization.

Retinal diseases generally are vision-threatening conditions that warrant appropriate clinical decision-making which currently solely dependents upon extensive clinical screening by specialized ophthalmologists. In the era where molecular assessment has improved dramatically, we aimed at the identification of biomarkers in 175 ocular fluids to classify four archetypical ocular conditions affecting the retina (age-related macular degeneration, idiopathic non-infectious uveitis, primary vitreoretinal lymphoma, and rhegmatogenous retinal detachment) with one single test. Unsupervised clustering of ocular proteins revealed a classification strikingly similar to the clinical phenotypes of each disease group studied. We developed and independently validated a parsimonious model based merely on three proteins; interleukin (IL)-10, IL-21, and angiotensin converting enzyme (ACE) that could correctly classify patients with an overall accuracy, sensitivity and specificity of respectively, 86.7%, 79.4% and 92.5%. Here, we provide proof-of-concept for molecular profiling as a diagnostic aid for ophthalmologists in the care for patients with retinal conditions.

Military members are required to complete the Post-Deployment Health Assessment on return from deployment and the Post-Deployment Health Reassessment (PHDRA) 90 to 180 days later, and we assessed the PDHRA's sensitivity and specificity in identifying posttraumatic stress disorder (PTSD) and depression after a military deployment among US Air Force personnel. We computed the PDHRA's sensitivity and specificity for depression and PTSD and developed a structural model to suggest possible improvements to it. For depression, sensitivity and specificity were 0.704 and 0.651, respectively; for PTSD, they were 0.774 and 0.650, respectively. Several variables produced significant direct effects on depression and trauma, suggesting that modifications could increase its sensitivity and specificity. The PDHRA was moderately effective in identifying airmen with depression and PTSD. It identified behavioral health concerns in many airmen who did not develop a diagnostic mental health condition. Its low level of specificity may result in reduced barriers to care and increased support services, key components of a public health approach to suicide prevention, for airmen experiencing subacute levels of distress after deployment, which may, in part, account for lower suicide rates among airmen after deployment.

A method and system for analyzing a source of data. The system and method involves initially training a system using a selected data signal, calculating at least two levels of sensitivity using a pattern recognition methodology, activating a first mode of alarm sensitivity to monitor the data source, activating a second mode of alarm sensitivity to monitor the data source and generating a first alarm signal upon the first mode of sensitivity detecting an alarm condition and a second alarm signal upon the second mode of sensitivity detecting an associated alarm condition. The first alarm condition and second alarm condition can be acted upon by an operator and/or analyzed by a specialist or computer program.

As genomic health care becomes commonplace, nurses will be asked to provide genomic care in all health care settings including acute care and critical care. Three common cardiac conditions are reviewed, Marfan syndrome, bicuspid aortic valve, and hypertrophic cardiomyopathy, to provide acute care and critical care nurses with an overview of these pathologies through the lens of genomics and relevant case studies. This information will help critical care nursing leaders become familiar with genetics related to common cardiac conditions and prepare acute care and critical care nurses for a new phase in patient diagnostics, with greater emphasis on early diagnosis and recognition of conditions before sudden cardiac death.

Time-dependent effects of prazosin on the development of methamphetamine conditioned hyperactivity and context-specific sensitization in mice.

White, André O; Rauhut, Anthony S

2014-04-15

The present experiments examined the effects of prazosin, a selective α₁-adrenergic receptor antagonist, on the development of methamphetamine conditioned hyperactivity and context-specific sensitization. Mice received an injection of vehicle (distilled water) or prazosin (0.5, 1.0 or 2.0 mg/kg) 30 min prior to a second injection of vehicle (saline) or methamphetamine (1.0 mg/kg) during the conditioning sessions (Experiment 1). Following the conditioning sessions, mice were tested for conditioned hyperactivity and then tested for context-specific sensitization. In subsequent experiments, mice received an injection of vehicle (distilled water) or prazosin (2.0 mg/kg) immediately (Experiment 2) or 24 h (Experiment 3) after the conditioning sessions and then tested for conditioned hyperactivity and context-specific sensitization. Prazosin dose-dependently blocked the development of methamphetamine conditioned hyperactivity and context-specific sensitization when administered prior to the methamphetamine during the conditioning phase; however nonspecific motor impairments also were observed (Experiment 1). Immediate (Experiment 2), but not the 24-h delay (Experiment 3), post-session administration of prazosin attenuated the development of methamphetamine conditioned hyperactivity and context-specific sensitization. Nonspecific motor impairments were not observed in these latter experiments. Collectively, these results suggest that the α₁-adrenergic receptor mediates the development of methamphetamine-conditioned hyperactivity and context-specific sensitization, perhaps by altering memory consolidation and/or reconsolidation processes.

2004-01-01

Background: The epidemiology, risks, and outcomes of errors in primary care are poorly understood. Malpractice claims brought for negligent adverse events offer a useful insight into errors in primary care. Methods: Physician Insurers Association of America malpractice claims data (1985–2000) were analyzed for proportions of negligent claims by primary care specialty, setting, severity, health condition, and attributed cause. We also calculated risks of a claim for condition-specific negligent events relative to the prevalence of those conditions in primary care. Results: Of 49 345 primary care claims, 26 126 (53%) were peer reviewed and 5921 (23%) were assessed as negligent; 68% of claims were for negligent events in outpatient settings. No single condition accounted for more than 5% of all negligent claims, but the underlying causes were more clustered with "diagnosis error" making up one third of claims. The ratios of condition-specific negligent event claims relative to the frequency of those conditions in primary care revealed a significantly disproportionate risk for a number of conditions (for example, appendicitis was 25 times more likely to generate a claim for negligence than breast cancer). Conclusions: Claims data identify conditions and processes where primary health care in the United States is prone to go awry. The burden of severe outcomes and death from malpractice claims made against primary care physicians was greater in primary care outpatient settings than in hospitals. Although these data enhance information about error related negligent events in primary care, particularly when combined with other primary care data, there are many operating limitations.

Background/Objectives The quality of care for geriatric conditions remains poor. The Assessing Care of Vulnerable Elders (ACOVE)-2 model (case finding, delegation of data collection, structured visit notes, physician and patient education, and linkage to community resources) improves the quality of care for geriatric conditions when implemented by primary care physicians (PCPs) or by nurse practitioners (NPs) co-managing care with an academic geriatrician. However, it is unclear whether community-based PCP-NP co-management can achieve similar results. Design Case study. Setting Two community-based primary care practices. Participants Patients > 75 years who screened positive for at least one condition: falls, urinary incontinence (UI), dementia, and depression. Intervention The ACOVE-2 model augmented by NP co-management of conditions. Measurements Quality of care by medical record review using ACOVE-3 quality indicators (QIs). Patients receiving co-management were compared with those who received PCP care alone in the same practices. Results Of 1084 screened patients, 658 (61%) screened positive for > 1 condition; 485 of these patients were randomly selected for chart review and triggered a mean of 7 QIs. A NP saw approximately half (49%) for co-management. Overall, patients received 57% of recommended care. Quality scores for all conditions (falls: 80% versus 34%; UI: 66% versus 19%; dementia: 59% versus 38%) except depression (63% versus 60%) were higher for patients seen by a NP. In analyses adjusted for gender, age of patient, number of conditions, site, and a NP estimate of medical management style, NP co-management remained significantly associated with receiving recommended care (p<0.001), as did the NP estimate of medical management style (p=0.02). Conclusion Compared to usual care using the ACOVE-2 model, NP co-management is associated with better quality of care for geriatric conditions in community-based primary care. PMID:23772723

Cultural Diversity Training: The Necessity of Cultural Competence for Health Care Providers and in Nursing Practice.

PubMed

Young, Susan; Guo, Kristina L

2016-01-01

The purpose of this article is to discuss the need to provide culturally sensitive care to the growing number of diverse health care consumers. A literature review of national standards and research on cultural competency was conducted and specifically focused on the field of nursing. This study supports the theory that cultural competence is learned over time and is a process of inner reflection and awareness. The domains of awareness, skill, and knowledge are essential competencies that must be gained by health care providers and especially for nurses. Although barriers to providing culturally sensitive care exist, gaining a better understanding of cultural competence is essential to developing realistic education and training techniques, which will lead to quality professional nursing practice for increasingly diverse populations.

Looking beyond "affordable" health care: cultural understanding and sensitivity-necessities in addressing the health care disparities of the U.S. Hispanic population.

Health disparities are pervasive in the United States; but among Hispanics, access to health care is encumbered by poverty, lack of insurance, legal status, and racial or minority status. Research has identified certain aspects of Hispanic culture, values, and traditions contributing to the nature of the Hispanic patient-doctor relationship and the quality of the health care service. Current educational efforts by nonprofit organizations, government, health professionals, and pharmaceutical manufacturers fail to address the needs for accessible and appropriately culture-sensitive information when approaching the diverse Hispanic community. Understanding Hispanics' consumptive practices and expectations surrounding medications is critical to the success of many treatment regimens. Recommendations are presented to address this health care issue.

The purpose of this study was to investigate the cultural sensitivity of nurses working in rural and urban hospitals in Turkey. The sampling of this descriptive and correlational study was composed of only 516 clinical nurses working in inpatient clinics. The data collection tools were the Socio-Demographic Questionnaire and the Intercultural Sensitivity Scale. A majority of the participating nurses experienced culture-related problems. Intercultural Sensitivity Scale results were partially high. The nurses had more problems in areas related to language barriers, patients' education level, and health perception about disease and religious beliefs when providing health care. Participants who were female, had an undergraduate or graduate education, had received in-service education on cultural care, or had taken transcultural nursing coursework obtained higher scores on the Intercultural Sensitivity Scale and its Interaction Engagement subscale. The cultural sensitivity level was 84.01 ± 9.1 (range = 43-107). The proportion of nurses who had received no in-service education was very high. They wanted to participate in an education program to gain better understanding of the culture of the society in which they lived. The results of the present study demonstrated that nurses should be prepared in cultural sensitivity and cultural competence. Continuing education and formal courses on cultural sensitivity for nursing professionals are essential for optimal health outcomes. Thus, inequalities in health could be prevented and the quality of health care could be improved. © 2017 Sigma Theta Tau International.

Potentially preventable hospitalizations in dementia: family caregiver experiences.

2017-07-01

Health crises in persons living with dementia challenge their caregivers to make pivotal decisions, often under pressure, and to act in new ways on behalf of their care recipient. Disruption of everyday routines and heightened stress are familiar consequences of these events. Hospitalization for acute illness or injury is a familiar health crisis in dementia. The focus of this study is to describe the lived experience of dementia family caregivers whose care recipients had a recent unplanned admission, and to identify potential opportunities for developing preventive interventions. Family caregivers (n = 20) of people with dementia who experienced a recent hospitalization due to an ambulatory care sensitive condition or fall-related injury completed phone interviews. Interviews used semi-structured protocols to elicit caregivers' reactions to the hospitalization and recollections of the events leading up to it. Analysis of interview data identified four major themes: (1) caregiver is uncertain how to interpret and act on the change; (2) caregiver is unable to provide necessary care; (3) caregiver experiences a personal crisis in response to the patient's health event; (4) mitigating factors may prevent caregiver crises. This study identifies a need for clinicians and family caregivers to work together to avoid health crises of both caregivers and people with dementia and to enable caregivers to manage the health of their care recipients without sacrificing their own health and wellness.

2007-03-16

To evaluate the cost-effectiveness of a prize-based intervention as an addition to usual care for stimulant abusers. This cost-effectiveness analysis is based on a randomized clinical trial implemented within the National Drug Abuse Treatment Clinical Trials Network. The trial was conducted at eight community-based outpatient psychosocial drug abuse treatment clinics. Four hundred and fifteen stimulant abusers were assigned to usual care (N=206) or usual care plus abstinence-based incentives (N=209) for 12 weeks. Participants randomized to the incentive condition earned the chance to draw for prizes for submitting substance negative samples; the number of draws earned increased with continuous abstinence time. Incremental cost-effectiveness ratios were estimated to compare prize-based incentives relative to usual care. The primary patient outcome was longest duration of confirmed stimulant abstinence (LDA). Unit costs were obtained via surveys administered at the eight participating clinics. Resource utilizations and patient outcomes were obtained from the clinical trial. Acceptability curves are presented to illustrate the uncertainty due to the sample and to provide policy relevant information. The incremental cost to lengthen the LDA by 1 week was 258 US dollars (95% confidence interval, 191-401 US dollars). Sensitivity analyses on several key parameters show that this value ranges from 163 to 269 US dollars. Compared with the usual care group, the incentive group had significantly longer LDAs and significantly higher costs.

1996-01-01

The author advocates a reproductive health care strategy to revitalize India's family welfare program. A major shift in focus is needed in population policy and programs to incorporate a gender-sensitive approach. That shift should help to clear the path toward improved health status for women and female children. Consensus reached at the UN's 1994 International Conference on Population and Development supported a change in population and development policies, affording women's empowerment, gender equality, and equity greater priority for a meaningful policy of human-centered sustainable development. Reproductive health care, reproductive health in practice, the quality of care in reproductive health, gender equality as a human right, and empowering women are discussed.

This study extends previous community-based studies on the prevalence and clinical characteristics of chemical intolerance in a sample of primary care clinic patients. We evaluated comorbid medical and psychiatric disorders, functional status, and rates of health care use. A total of 400 patients were recruited from 2 family medicine clinic waiting rooms in San Antonio, Texas. Patients completed the validated Quick Environmental Exposure and Sensitivity Inventory (QEESI) to assess chemical intolerance; the Primary Care Evaluation of Mental Disorders (PRIME-MD) screen for possible psychiatric disorders; the Dartmouth-Northern New England Primary Care Cooperative Information Project (Dartmouth COOP) charts for functional status; and the Healthcare Utilization Questionnaire. Overall, 20.3% of the sample met criteria for chemical intolerance. The chemically intolerant group reported significantly higher rates of comorbid allergies and more often met screening criteria for possible major depressive disorder, panic disorder, generalized anxiety disorder, and alcohol abuse disorder, as well as somatization disorder. The total number of possible mental disorders was correlated with chemical intolerance scores (P <.001). Controlling for demographics, patients with chemical intolerance were significantly more likely to have poorer functional status, with trends toward increased medical service use when compared with non-chemically intolerant patients. After controlling for comorbid psychiatric conditions, the groups differed significantly only regarding limitations of social activities. Chemical intolerance occurs in 1 of 5 primary care patients yet is rarely diagnosed by busy practitioners. Psychiatric comorbidities contribute to functional limitations and increased health care use. Chemical intolerance offers an etiologic explanation. Symptoms may resolve or improve with the avoidance of salient chemical, dietary (including caffeine and alcohol), and drug triggers. Given greater medication intolerances in chemical intolerance, primary care clinicians could use the QEESI to identify patients for appropriate triage to comprehensive nonpharmacologic care.

Introduction Health-care seeking behaviour is important as it determines acceptance of health care and outcomes of chronic conditions but it has been investigated to a limited extent among persons with diabetes in developing countries. The aim of the study was to explore health-care seeking behaviour among persons with type 2 diabetes to understand reasons for using therapies offered by traditional healers. Methods Descriptive study using focus-group interviews. Three purposive focus-groups were conducted in 2011 of 10 women and 7 men aged 39–72 years in Uganda. Data were collected through semi-structured interviews and qualitatively analysed according to a method described for focus-groups. Results Reasons for seeking help from traditional healers were symptoms related to diabetes such as polydipsia, fatigue and decreased sensitivity in lower limbs. Failure of effect from western medicine was also reported. Treatment was described to be unknown extracts, of locally made products taken as herbs or food, and participants had sought help from different health facilities with the help of relatives and friends. Conclusion The pattern of seeking care was inconsistent, with a switch between different health care providers under the influence of the popular and folk sectors. Despite beliefs in using different healthcare providers seeking complementary and alternative medicine, participants still experienced many physical health problems related to diabetes complications. Health professionals need to be aware of the risk of switches between different health care providers, and develop strategies to initiate health promotion interventions to include in the care actors of significance to the patient from the popular, folk and professional sectors, to maintain continuity of effective diabetes care.

Shomaker, T S; Ashburn, M A

2000-03-01

Accurate and sensitive communication of health care information is essential to effective patient management in the pain clinic, operating room, other health care settings. However, information relating to the health care status of a patient is sensitive and may be embarrassing or damaging if it falls into the wrong hands. Ethical cannons of medicine and statutory provisions have emphasized the obligation of the physician to safeguard patient confidences. However, threats to the confidentiality of medical information abound and are even more significant in our age of instantaneous communication characterized by the growing use of email, facsimile, and the Internet. This article outlines legal issues relating to communication in three key areas of health care law: confidentiality/breach of privacy, informed consent, and defamation. The major principles of the law in these areas are discussed and case studies are used to illustrate key points and give simple preventive strategies to help steer the delicate balance between sharing important healthcare information and protecting sensitive patient information.

The performance of a polymerase chain reaction-based point-of-care assay, the cobas Strep A Nucleic Acid Test for use on the cobas Liat System (cobas Liat Strep A assay), for the detection of group A Streptococcus bacteria was evaluated in primary care settings. Throat swab specimens from 427 patients were tested with the cobas Liat Strep A assay and a rapid antigen detection test (RADT) by existing medical staff at 5 primary care clinics, and results were compared with bacterial culture. The cobas Liat Strep A assay demonstrated equivalent sensitivity (97.7%) and specificity (93.3%) to reference culture with a 15-minute turnaround time. In comparison to RADTs, the cobas Liat Strep A assay showed improved sensitivity (97.7% Liat vs 84.5% RADT). The Clinical Laboratory Improvement Amendments-waived cobas Liat Strep A assay demonstrated the ease of use and improved turnaround time of RADTs along with the sensitivity of culture.

Evidence-based Evaluation and Management of Chronic Cough.

Chronic cough is common and has a significant impact on the wellbeing of patients and the use and cost of health care services. Traditionally the approach to chronic cough in patients who are nonsmokers and are not taking an angiotensin-converting enzyme inhibitor has focused on the diagnosis and management of the upper airway cough syndrome, asthma, and reflux disease. The evaluation of patients with chronic cough frequently involves trials of empiric therapy for these 3 conditions. Chronic cough may be perpetuated by abnormalities of the cough reflex and sensitization of its afferent and central components. Copyright © 2016 Elsevier Inc. All rights reserved.

The Cosmetic Ingredient Review Expert Panel (Panel) reviewed the product use, formulation, and safety data of 115 amino acid alkyl amides, which function as skin and hair conditioning agents and as surfactants-cleansing agents in personal care products. Safety test data on dermal irritation and sensitization for the ingredients with the highest use concentrations, lauroyl lysine and sodium lauroyl glutamate, were reviewed and determined to adequately support the safe use of the ingredients in this report. The Panel concluded that amino acid alkyl amides are safe in the present practices of use and concentration in cosmetics, when formulated to be nonirritating.

Sex and racial differences in preference for a caring morality in a corporate environment that promotes diversity and equal opportunity.

Jones, Nona J

2002-10-01

This study investigated the caring moral perspective of managers in a corporation recognized as being a champion of promoting diversity and equal opportunity. Caring is described as a morality of responsibility and relationship, a sensitivity to the needs of persons. The study was based on the prediction that the attachment and caring shown elsewhere to be characteristic of the morality of females would be characteristic of all managers, regardless of sex or race in this kind of corporate environment. 121 male and female, African-American and Euro-American managers responded to a survey using three subscales of a Caring Morality Inventory: caring orientation, use of intuition and feeling to make a judgment, and concern with others in decision-making. Analysis showed female managers, regardless of race, scored significantly higher on the Caring Morality scale than the male managers, supporting other findings of sex differences in caring moral perspective and suggesting that working for a company actively promoting diversity and equal opportunity does not cancel out these differences. In addition, for this study it was assumed that, although African Americans, in general, may have been sensitized to lean more toward a caring morality, any racial differences in caring morality would be cancelled out by the fact that all of the managers work for the same prodiversity and, by assumption, more sensitive company. The Euro-American managers, regardless of sex, actually scored higher on the Caring Morality scale than did the African-American managers, with the difference being attributable solely to the greater tendency of the Euro-American managers to use intuition and feeling to make a judgment.

IMPORTANCE Health care spending on children in the United States continues to rise, yet little is known about how this spending varies by condition, age and sex group, and type of care, nor how these patterns have changed over time. OBJECTIVE To provide health care spending estimates for children and adolescents 19 years and younger in the United States from 1996 through 2013, disaggregated by condition, age and sex group, and type of care. EVIDENCE REVIEW Health care spending estimates were extracted from the Institute for Health Metrics and Evaluation Disease Expenditure 2013 project database. This project, based on 183 sources of data and 2.9 billion patient records, disaggregated health care spending in the United States by condition, age and sex group, and type of care. Annual estimates were produced for each year from 1996 through 2013. Estimates were adjusted for the presence of comorbidities and are reported using inflation-adjusted 2015 US dollars. FINDINGS From 1996 to 2013, health care spending on children increased from $149.6 (uncertainty interval [UI], 144.1–155.5) billion to $233.5 (UI, 226.9–239.8) billion. In 2013, the largest health condition leading to health care spending for children was well-newborn care in the inpatient setting. Attention-deficit/hyperactivity disorder and well-dental care (including dental check-ups and orthodontia) were the second and third largest conditions, respectively. Spending per child was greatest for infants younger than 1 year, at $11 741 (UI, 10 799–12 765) in 2013. Across time, health care spending per child increased from $1915 (UI, 1845–1991) in 1996 to $2777 (UI, 2698–2851) in 2013. The greatest areas of growth in spending in absolute terms were ambulatory care among all types of care and inpatient well-newborn care, attention-deficit/hyperactivity disorder, and asthma among all conditions. CONCLUSIONS AND RELEVANCE These findings provide health policy makers and health care professionals with evidence to help guide future spending. Some conditions, such as attention-deficit/hyperactivity disorder and inpatient well-newborn care, had larger health care spending growth rates than other conditions. PMID:28027344

The increasing prevalence of gestational diabetes mellitus (GDM) among women of different ethnic backgrounds provides new challenges for health care professionals, who often find it difficult to provide information about the management of this disease to such individuals. Mobile health (mHealth) may act as a useful tool for blood sugar control and care process enhancement. However, little is known about health care professionals' experiences and attitudes toward the use of mHealth for women with GDM. The aim of this study was to explore how health care professionals perceived the provision of care to pregnant women who managed their GDM using the culture-sensitive Pregnant+ app in a randomized controlled trial. Individual interviews with 9 health care professionals providing care for women with GDM were conducted. Braun and Clark's method of thematic content analysis inspired the analysis. This study included health care professionals who were primarily responsible for providing care to participants with GDM in the Pregnant+ randomized controlled trial at 5 diabetes outpatient clinics in Oslo, Norway. Health care professionals perceived mHealth, particularly the Pregnant+ app, as an appropriate tool for the care of women with GDM, who were described as individuals comprising a heterogeneous, motivated group that could be easily approached with health-related information. Some participants reported challenges with respect to provision of advice to women with different food cultures. The advantages of the Pregnant+ app included provision of information that women could access at home, the information provided being perceived as trustworthy by health care professionals, the culture sensitivity of the app, and the convenience for women to register blood sugar levels. Technical problems, particularly those associated with the automatic transfer of blood glucose measurements, were identified as the main barrier to the use of the Pregnant+ app. Strict inclusion criteria and the inclusion of participants who could not speak Norwegian were the main challenges in the recruitment process for the randomized controlled trial. The findings of this study suggest that mHealth is a useful tool to enhance the care provided by health care professionals to women with GDM. Future mobile apps for the management of GDM should be developed by a trustworthy source and in cooperation with health care professionals. They should also be culture sensitive and should not exhibit technical problems. ©Lisa Garnweidner-Holme, Therese Hoel Andersen, Mari Wastvedt Sando, Josef Noll, Mirjam Lukasse.

Our interest in chronic conditions is due to the fact that, worldwide, chronic diseases have overtaken infectious diseases as the leading cause of death and disability, so their management represents an important challenge for health systems. The aim of this study was to compare the performance of primary health care services in managing diabetes, congestive heart failure (CHF) and coronary heart disease (CHD), by age group. This population-based retrospective cohort study was conducted in Italy, enrolling 1,948,622 residents ≥ 16 years old. A multilevel regression model was applied to analyze compliance to care processes with explanatory variables at both patient and district level, using age group as an independent variable, and adjusting for sex, citizenship, disease duration, and Charlson index on the first level, and for District Health Unit on the second level. The quality of chronic disease management showed an inverted U-shaped relationship with age. In particular, our findings indicate lower levels for young adults (16-44 year-olds), adults (45-64), and oldest old (+85) than for patients aged 65-74 in almost all quality indicators of CHD, CHF and diabetes management. Young adults (16-44 y), adults (45-64 y), the very old (75-84 y) and the oldest old (+85 y) patients with CHD, CHF and diabetes are less likely than 65-74 year-old patients to be monitored and treated using evidence-based therapies, with the exceptions of echocardiographic monitoring for CHF in young adult patients, and renal monitoring for CHF and diabetes in the very old. Our study shows that more effort is needed to ensure that primary health care systems are sensitive to chronic conditions in the young and in the very elderly.

Objective Genital and sexual pain is still neglected. Consequences may be dramatic, since infertility and sexual dysfunction may be reciprocally linked. This is the first study to focus on the identification of cases of vaginismus in the ART scenario and on the introduction of intra-cycle interventions as part of a comprehensive, integrated and patient-centered perspective. Methods This observational prospective study looked into 425 IVF/ICSI cycles and 226 frozen embryo transfers carried out from January 1, 2015 to December 31, 2016, and found seven cases of vaginismus. Within a six-month period, a questionnaire placed on SurveyMonkey was sent twice to 228 ART centers in Latin America. The purpose was to learn how often cases of vaginismus were found in ART centers and the perceptions around the presence of this condition. Results The few centers that took the time to answer the questionnaire (24/10.5%) stated that the number of cases in which they had trouble performing control ultrasound examination or needed to perform transfers with patients under sedation was not significant. Although 81% agreed that the incidence of these conditions is low, no references were made to cases of vaginismus, dyspareunia or sexual dysfunction. Our multidisciplinary team found seven cases of vaginismus, involving women with higher education degrees with a mean age of 37.8 years and married for a mean of four years. Although two reported they were able to tolerate intercourse, all reported undergoing treatments such as using vaginal dilators (3), psychotherapy (4) and psychiatric care (1). The care provided by the staff was designed to mitigate patient suffering. Conclusion Gentle care and sensitive listening should be integral components in the work of multidisciplinary teams to identify women with vaginismus and offer couples better quality treatment.

LeBlanc, Raeann G; Jacelon, Cynthia S

2018-03-24

The aim of this study was to clarify the concept of self-care among older people living with chronic health conditions. This concept clarification will assist nurses in addressing self-care among older people through research, policy and practice in offering an expanded conceptual model. Several policy influences over the past decade directly relate to the increased importance and economic necessity to require self-directed care for older people living with chronic health conditions to maintain their care at home in the community. A selective review of literature on the concept of self-care included 31 sources. The Norris Concept Clarification method (1982) was used for clarification. The phenomenon is described historically according to its antecedents, attributes and consequences. A proposed definition is provided based on the clarification of this concept. A conceptual model is presented through an ecological framework. Self-care among older people living with chronic conditions is multidimensional and has multilevel influences (individual, community, system levels) and is mediated by the contexts and processes of ageing. Self-care originates along one's life course and is learned. Self-care responses are based on care needs when living with chronic health conditions. Self-care is an individual capacity, disposition and activity older people manifest in living with multiple chronic conditions. These features (capacity, disposition, action) influence one another and are hierarchical and continuous. Research, practice and policies that promote self-care among older people can focus on these features to improve health outcomes and promote new models of care consistent with personal development and chronic care needs in older age. This concept clarification can offer a model to support self-care among older people living with chronic conditions. © 2018 John Wiley & Sons Ltd.

Health Literacy and Communication Quality in Health Care Organizations

The relationship between limited health literacy and poor health may be due to poor communication quality within health care delivery organizations. We explored the relationship between health literacy status and receiving patient-centered communication in clinics and hospitals serving communication-vulnerable patient populations. Thirteen health care organizations nationwide distributed a survey to 5,929 patients. All patients completed seven items assessing patient-centered communication. One third also completed three items assessing health literacy. The majority of patients had self-reported health literacy challenges, reporting problems learning about their medical condition because of difficulty understanding written information (53%), a lack of confidence in completing medical forms by themselves (61%), and needing someone to help them read hospital/clinic materials (57%). Logistic regression models showed that, after adjustment for patient demographic characteristics and health care organization type, patients with limited health literacy were 28–79% less likely than those with adequate health literacy to report their health care organization “always” provides patient-centered communication across seven communication items. Using a scaled composite of these items, limited health literacy remained associated with lower reported communication quality. These results suggest that improving communication quality in health care organizations might help to address the challenges facing patients with limited health literacy. They also highlight that efforts to address the needs of patients with limited health literacy should be sensitive to the range of communication challenges confronting these patients and their caregivers.

Objective To describe the average primary care physician consultation length in economically developed and low-income/middle-income countries, and to examine the relationship between consultation length and organisational-level economic, and health outcomes. Design and outcome measures This is a systematic review of published and grey literature in English, Chinese, Japanese, Spanish, Portuguese and Russian languages from 1946 to 2016, for articles reporting on primary care physician consultation lengths. Data were extracted and analysed for quality, and linear regression models were constructed to examine the relationship between consultation length and health service outcomes. Results One hundred and seventy nine studies were identified from 111 publications covering 28 570 712 consultations in 67 countries. Average consultation length differed across the world, ranging from 48 s in Bangladesh to 22.5 min in Sweden. We found that 18 countries representing about 50% of the global population spend 5 min or less with their primary care physicians. We also found significant associations between consultation length and healthcare spending per capita, admissions to hospital with ambulatory sensitive conditions such as diabetes, primary care physician density, physician efficiency and physician satisfaction. Conclusion There are international variations in consultation length, and it is concerning that a large proportion of the global population have only a few minutes with their primary care physicians. Such a short consultation length is likely to adversely affect patient healthcare and physician workload and stress. PMID:29118053

Most malaria rapid diagnostic tests (RDTs) use HRP2 detection, including Paracheck-Pf(R), but their utility is limited by persistent false positivity after treatment. PLDH-based tests become negative more quickly, but sensitivity has been reported below the recommended standard of 90%. A new pLDH test, CareStart three-line P.f/PAN-pLDH, claims better sensitivity with continued rapid conversion to negative. The study aims were to 1) compare sensitivity and specificity of CareStart to Paracheck-Pf(R) to diagnose falciparum malaria in children under five years of age, 2) assess how quickly false-positive CareStart tests become negative and 3) evaluate ease of use and inter-reader agreement of both tests. Participants were included if they were aged between two and 59 months, presenting to a Médecins Sans Frontières community health centre in eastern Sierra Leone with suspected malaria defined as fever (axillary temperature > 37.5 degrees C) and/or history of fever in the previous 72 hours and no signs of severe disease. The same capillary blood was used for the RDTs and the blood slide, the latter used as the gold standard reference. All positive participants were treated with supervised artesunate and amodiaquine treatment for three days. Participants with a persistent false-positive CareStart, but a negative blood slide on Day 2, were followed with repeated CareStart and blood slide tests every seven days until CareStart became negative or a maximum of 28 days. Sensitivity of CareStart was 99.4% (CI 96.8-100.0, 168/169) and of Paracheck-Pf(R), 98.8% (95% CI 95.8-99.8, 167/169). Specificity of CareStart was 96.0% (CI 91.9-98.4, 167/174) and of Paracheck-Pf(R), 74.7% (CI 67.6-81.0, 130/174) (p < 0.001). Neither test showed any change in sensitivity with decreasing parasitaemia. Of the 155 eligible follow-up CareStart participants, 63.9% (99/155) had a false-positive test on day 2, 21.3% (33/155) on day 7, 5.8% (9/155) on day 14, 1.9% (3/155) on day 21 and 0.6% (1/155) on day 28. The median time for test negativity was seven days. CareStart was as easy to use and interpret as Paracheck-Pf(R) with excellent inter-reader agreement. Both RDTs were highly sensitive, met WHO standards for the detection of falciparum malaria monoinfections where parasitaemia was >100 parasites/mul and were easy to use. CareStart persistent false positivity decreased quickly after successful anti-malarial treatment, making it a good choice for a RDT for a hyperendemic falciparum malaria area.

The primary objective of this study was to assess the impact of pediatric pain-related conditions on health care expenditures. We analyzed data from a nationally representative sample of 6- to 17-year-old children captured in the 2007 National Health Interview Survey and 2008 Medical Expenditure Panel Survey. Health care expenditures of children with pain-related conditions were compared with those of children without pain-related conditions. Pain-related conditions were associated with incremental health care expenditures of $1339 (95% confidence interval [CI], $248-$2447) per capita. Extrapolated to the nation, pediatric pain-related conditions were associated with $11.8 billion (95% CI, $2.18-$21.5 billion) in total incremental health care expenditures. The incremental health care expenditures associated with pediatric pain-related conditions were similar to those of attention deficit and hyperactivity disorder ($9.23 billion; 95% CI, $1.89-$18.1 billion), but more than those associated with asthma ($5.35 billion; 95% CI, $0-$12.3 billion) and obesity ($0.73 billion; 95% CI, $6.28-$8.81 billion). Health care expenditures for pediatric pain-related conditions exert a considerable economic burden on society. Efforts to prevent and treat pediatric pain-related conditions are urgently needed.

Evaluating the impact of a ‘virtual clinic’ on patient experience, personal and provider costs of care in urinary incontinence: A randomised controlled trial

PubMed Central

2018-01-01

Objective To evaluate the impact of using a ‘virtual clinic’ on patient experience and cost in the care of women with urinary incontinence. Materials and methods Women, aged > 18 years referred to a urogynaecology unit were randomised to either (1) A Standard Clinic or (2) A Virtual Clinic. Both groups completed a validated, web-based interactive, patient-reported outome measure (ePAQ-Pelvic Floor), in advance of their appointment followed by either a telephone consultation (Virtual Clinic) or face-to-face consultation (Standard Care). The primary outcome was the mean ‘short-term outcome scale’ score on the Patient Experience Questionnaire (PEQ). Secondary Outcome Measures included the other domains of the PEQ (Communications, Emotions and Barriers), Client Satisfaction Questionnaire (CSQ), Short-Form 12 (SF-12), personal, societal and NHS costs. Results 195 women were randomised: 98 received the intervention and 97 received standard care. The primary outcome showed a non-significant difference between the two study arms. No significant differences were also observed on the CSQ and SF-12. However, the intervention group showed significantly higher PEQ domain scores for Communications, Emotions and Barriers (including following adjustment for age and parity). Whilst standard care was overall more cost-effective, this was minimal (£38.04). The virtual clinic also significantly reduced consultation time (10.94 minutes, compared with a mean duration of 25.9 minutes respectively) and consultation costs compared to usual care (£31.75 versus £72.17 respectively), thus presenting potential cost-savings in out-patient management. Conclusions The virtual clinical had no impact on the short-term dimension of the PEQ and overall was not as cost-effective as standard care, due to greater clinic re-attendances in this group. In the virtual clinic group, consultation times were briefer, communication experience was enhanced and personal costs lower. For medical conditions of a sensitive or intimate nature, a virtual clinic has potential to support patients to communicate with health professionals about their condition. PMID:29346378

[Trauma-Informed Peer Counselling in the Care of Refugees with Trauma-Related Disorders].

Wöller, Wolfgang

2016-09-01

Providing adequate culture-sensitive care for a large number of refugees with trauma-related disorders constitutes a major challenge. In this context, peer support and trauma-informed peer counselling can be regarded as a valuable means to complement the psychosocial care systems. In recent years, peer support and peer education have been successfully implemented e. g. in health care education, in psychiatric care, and in the treatment of traumatized individuals. Only little research data is available for traumatized refugees. However, results are encouraging. A program is presented which integrates trauma-informed peer educators (TIP) with migration background in the care of traumatized refugees. Peers' responsibility includes emotional support and understanding the refugees' needs, sensitizing for trauma-related disorders, providing psychoeducation, and teaching trauma-specific stabilization techniques under supervision of professional psychotherapists. © Georg Thieme Verlag KG Stuttgart · New York.

SENSITIVITY OF CONDITIONAL-DISCRIMINATION PERFORMANCE TO WITHIN-SESSION VARIATION OF REINFORCER FREQUENCY

PubMed Central

Ward, Ryan D; Odum, Amy L

2008-01-01

The present experiment developed a methodology for assessing sensitivity of conditional-discrimination performance to within-session variation of reinforcer frequency. Four pigeons responded under a multiple schedule of matching-to-sample components in which the ratio of reinforcers for correct S1 and S2 responses was varied across components within session. Initially, five components, each arranging a different reinforcer-frequency ratio (from 1∶9 to 9∶1), were presented randomly within a session. Under this condition, sensitivity to reinforcer frequency was low. Sensitivity failed to improve after extended exposure to this condition, and under a condition in which only three reinforcer-frequency ratios were varied within session. In a later condition, three reinforcer-frequency ratios were varied within session, but the reinforcer-frequency ratio in effect was differentially signaled within each component. Under this condition, values of sensitivity were similar to those traditionally obtained when reinforcer-frequency ratios for correct responses are varied across conditions. The effects of signaled vs. unsignaled reinforcer-frequency ratios were replicated in two subsequent conditions. The present procedure could provide a practical alternative to parametric variation of reinforcer frequency across conditions and may be useful in characterizing the effects of a variety of manipulations on steady-state sensitivity to reinforcer frequency.

Stress has a strong influence on pain sensitivity. However, the direction of this influence is unclear. Recent studies reported both decreased and increased pain sensitivities under stress, and one hypothesis is that interindividual differences account for these differences. The aim of our study was to investigate the effect of stress on individual pain sensitivity in a relatively large female sample. Eighty female participants were included. Pain thresholds and temporal summation of pain were tested before and after stress, which was induced by the Mannheim Multicomponent Stress Test. In an independent sample of 20 women, correlation coefficients between 0.45 and 0.89 indicated relatively high test-retest reliability for pain measurements. On average, there were significant differences between pain thresholds under non-stress and stress conditions, indicating an increased sensitivity to pain under stress. No significant differences between non-stress and stress conditions were found for temporal summation of pain. On an individual basis, both decreased and increased pain sensitivities under stress conditions based on Jacobson's criteria for reliable change were observed. Furthermore, we found significant negative associations between pain sensitivity under non-stress conditions and individual change of pain sensitivity under stress. Participants with relatively high pain sensitivity under non-stress conditions became less sensitive under stress and vice versa. These findings support the view that pain sensitivity under stress shows large interindividual variability, and point to a possible dichotomy of altered pain sensitivity under stress.

Rapid diagnostic tests (RDTs) are alternative methods for microscopy in the diagnosis of malaria in resource limited settings. Among commercially available RDTs, CareStart™ Malaria test was found to show reliable results. This study evaluated the performance of CareStart™ Malaria Combo test kit in Northwestern Tigray in Ethiopia. Blood samples were collected from 320 malaria-suspected patients at Mayani Hospital in Northwestern Tigray from December 2015 to March 2016. All blood samples were examined using both light microscopy and CareStart™ Malaria HRP2/pLDH Combo Test kit. Statistical analyses were performed using SPSS version 20. The overall parasite positivity using light microscopy and CareStart™ RDT was 41 (12.8%) and 43 (13.4%), respectively. The sensitivity and specificity of CareStart™ RDT, regardless of species, were found to be 95.4 and 99.3%, respectively. Furthermore, the sensitivity of CareStart™ RDT for Plasmodium falciparum or mixed infection and non-falciparum malaria parasites was 94.4 and 85.0%, respectively while the specificity was found to be 98.9 and 99.7%, respectively. The agreement between the two test methods was "excellent" with a kappa value of 0.92. CareStart™ RDT has very good sensitivity and specificity for malaria diagnosis. The test kit also has an excellent agreement with light microscopy. It is therefore useful in resource-limited areas where microscopy is not available.

To determine whether hospital mortality rates changed in New Jersey after implementation of a law that changed hospital payment from a regulated system based on hospital cost to price competition with reduced subsidies for uncompensated care and whether changes in mortality rates were affected by hospital market conditions. State discharge data for New Jersey and New York from 1990 to 1996. Study Design. We used an interrupted time series design to compare risk-adjusted in-hospital mortality rates between states over time. We compared the effect sizes in markets with different levels of health maintenance organization penetration and hospital market concentration and tested the sensitivity of our results to different approaches to defining hospital markets. The study sample included all patients under age 65 admitted to New Jersey or New York hospitals with stroke, hip fracture, pneumonia, pulmonary embolism, congestive heart failure, hip fracture, or acute myocardial infarction (AMI). Mortality among patients in New Jersey improved less than in New York by 0.4 percentage points among the insured (p=.07) and 0.5 percentage points among the uninsured (p=.37). There was a relative increase in mortality for patients with AMI, congestive heart failure, and stroke, especially for uninsured patients with these conditions, but not for patients with the other four conditions we studied. Less competitive hospital markets were significantly associated with a relative decrease in mortality among insured patients. Market-based reforms may adversely affect mortality for some conditions but it appears the effects are not universal. Insured patients in less competitive markets fared better in the transition to price competition.

Variable postpartum responsiveness among humans and other primates with "cooperative breeding": A comparative and evolutionary perspective.

PubMed

Hrdy, Sarah B

2016-01-01

This article is part of a Special Issue "Parental Care".Until recently, evolutionists reconstructing mother-infant bonding among human ancestors relied on nonhuman primate models characterized by exclusively maternal care, overlooking the highly variable responsiveness exhibited by mothers in species with obligate reliance on allomaternal care and provisioning. It is now increasingly recognized that apes as large-brained, slow maturing, and nutritionally dependent for so long as early humans were, could not have evolved unless "alloparents" (group members other than genetic parents), in addition to parents, had helped mothers to care for and provision offspring, a rearing system known as "cooperative breeding." Here I review situation-dependent maternal responses ranging from highly possessive to permissive, temporarily distancing, rejecting, or infanticidal, documented for a small subset of cooperatively breeding primates. As in many mammals, primate maternal responsiveness is influenced by physical condition, endocrinological priming, prior experience and local environments (especially related to security). But mothers among primates who evolved as cooperative breeders also appear unusually sensitive to cues of social support. In addition to more "sapient" or rational decision-making, humankind's deep history of cooperative breeding must be considered when trying to understand the extremely variable responsiveness of human mothers.

Multiple Levels of Suffering: Discrimination in Health-Care Settings is Associated With Enhanced Laboratory Pain Sensitivity in Sickle Cell Disease.

People living with sickle cell disease (SCD) experience severe episodic and chronic pain and frequently report poor interpersonal treatment within health-care settings. In this particularly relevant context, we examined the relationship between perceived discrimination and both clinical and laboratory pain. Seventy-one individuals with SCD provided self-reports of experiences with discrimination in health-care settings and clinical pain severity, and completed a psychophysical pain testing battery in the laboratory. Discrimination in health-care settings was correlated with greater clinical pain severity and enhanced sensitivity to multiple laboratory-induced pain measures, as well as stress, depression, and sleep. After controlling for relevant covariates, discrimination remained a significant predictor of mechanical temporal summation (a marker of central pain facilitation), but not clinical pain severity or suprathreshold heat pain response. Furthermore, a significant interaction between experience with discrimination and clinical pain severity was associated with mechanical temporal summation; increased experience with discrimination was associated with an increased correlation between clinical pain severity and temporal summation of pain. Perceived discrimination within health-care settings was associated with pain facilitation. These findings suggest that discrimination may be related to increased central sensitization among SCD patients, and more broadly that health-care social environments may interact with pain pathophysiology.

High frequency electrical stimulation concurrently induces central sensitization and ipsilateral inhibitory pain modulation.

PubMed

Vo, L; Drummond, P D

2013-03-01

In healthy humans, analgesia to blunt pressure develops in the ipsilateral forehead during various forms of limb pain. The aim of the current study was to determine whether this analgesic response is induced by ultraviolet B radiation (UVB), which evokes signs of peripheral sensitization, or by high-frequency electrical stimulation (HFS), which triggers signs of central sensitization. Before and after HFS and UVB conditioning, sensitivity to heat and to blunt and sharp stimuli was assessed at and adjacent to the treated site in the forearm. In addition, sensitivity to blunt pressure was measured bilaterally in the forehead. The effect of ipsilateral versus contralateral temple cooling on electrically evoked pain in the forearm was then examined, to determine whether HFS or UVB conditioning altered inhibitory pain modulation. UVB conditioning triggered signs of peripheral sensitization, whereas HFS conditioning triggered signs of central sensitization. Importantly, ipsilateral forehead analgesia developed after HFS but not UVB conditioning. In addition, decreases in electrically evoked pain at the HFS-treated site were greater during ipsilateral than contralateral temple cooling, whereas decreases at the UVB-treated site were similar during both procedures. HFS conditioning induced signs of central sensitization in the forearm and analgesia both in the ipsilateral forehead and the HFS-treated site. This ipsilateral analgesia was not due to peripheral sensitization or other non-specific effects, as it failed to develop after UVB conditioning. Thus, the supra-spinal mechanisms that evoke central sensitization might also trigger a hemilateral inhibitory pain modulation process. This inhibitory process could sharpen the boundaries of central sensitization or limit its spread. © 2012 European Federation of International Association for the Study of Pain Chapters.

New models of delivering primary care are being implemented in various countries. In Quebec, Family Medicine Groups (FMGs) are a team-based approach to enhance access to, and coordination of, care. We examined whether physicians' and patients' characteristics predicted their participation in this new model of primary care. Using provincial administrative data, we created a population cohort of Quebec's vulnerable patients. We collected data before the advent of FMGs on patients' demographic characteristics, chronic illnesses and health service use, and their physicians' demographics, and practice characteristics. Multivariate regression was used to identify key predictors of joining a FMG among both patients and physicians. Patients who eventually enrolled in a FMG were more likely to be female, reside outside of an urban region, have a lower SES status, have diabetes and congestive heart failure, visit the emergency department for ambulatory sensitive conditions and be hospitalized for any cause. They were also less likely to have hypertension, visit an ambulatory clinic and have a usual provider of care. Physicians who joined a FMG were less likely to be located in urban locations, had fewer years in medical practice, saw more patients in hospital, and had patients with lower morbidity. Physicians' practice characteristics and patients' health status and health care service use were important predictors of joining a FMG. To avoid basing policy decisions on tenuous evidence, policymakers and researchers should account for differential selection into team-based primary health care models. Copyright © 2014.

Implementing programs for chronic illness management: the case of hypertension services.

1997-11-01

This article describes the process by which HealthSystem Minnesota (a vertically integrated health care organization), functioning in a competitive managed care environment, has been implementing a hypertension services program. The program involves a team approach to care, with emphasis on patient participation in treatment; decentralized care delivery by nurse coordinators at primary care practice sites; ongoing training and education for patients and providers; and the continuous monitoring and evaluation of patient outcomes and satisfaction. JOB-LEVEL ISSUES: A variety of issues, such as the role and responsibilities of the nurse coordinator, became evident as the program moved towards operational status at four primary care practice sites, which prolonged the implementation period. PROCESS-LEVEL ISSUES: Issues relating to work process changes were more complicated to resolve and required, in some cases, changes in the proposed model. The most significant process-level issues related to educating physicians about the program to secure their participation and support. ORGANIZATION-LEVEL ISSUES: Such issues, which were the most difficult for program implementors to anticipate and resolve, included an organizational culture that emphasized decision making autonomy at primary practice sites. In part, the difficulty encountered in resolving organization-level issues reflected the implementors' lack of awareness of the strength or complexity of the environmental pressures facing the organization, as well as a lack of sensitivity to nuances relating to organizational culture. Two groups of hypertensive patients--at the implementation and comparison sites--will be compared with respect to satisfaction with care, clinical outcomes, and costs. Expansion of the model to patients with other chronic conditions is under consideration.

Lung protective ventilation reduces mortality in patients with acute lung injury, but underrecognition of acute lung injury has limited its use. We recently validated an automated electronic acute lung injury surveillance system in patients with major trauma in a single intensive care unit. In this study, we assessed the system's performance as a prospective acute lung injury screening tool in a diverse population of intensive care unit patients. Patients were screened prospectively for acute lung injury over 21 wks by the automated system and by an experienced research coordinator who manually screened subjects for enrollment in Acute Respiratory Distress Syndrome Clinical Trials Network (ARDSNet) trials. Performance of the automated system was assessed by comparing its results with the manual screening process. Discordant results were adjudicated blindly by two physician reviewers. In addition, a sensitivity analysis using a range of assumptions was conducted to better estimate the system's performance. The Hospital of the University of Pennsylvania, an academic medical center and ARDSNet center (1994-2006). Intubated patients in medical and surgical intensive care units. None. Of 1270 patients screened, 84 were identified with acute lung injury (incidence of 6.6%). The automated screening system had a sensitivity of 97.6% (95% confidence interval, 96.8-98.4%) and a specificity of 97.6% (95% confidence interval, 96.8-98.4%). The manual screening algorithm had a sensitivity of 57.1% (95% confidence interval, 54.5-59.8%) and a specificity of 99.7% (95% confidence interval, 99.4-100%). Sensitivity analysis demonstrated a range for sensitivity of 75.0-97.6% of the automated system under varying assumptions. Under all assumptions, the automated system demonstrated higher sensitivity than and comparable specificity to the manual screening method. An automated electronic system identified patients with acute lung injury with high sensitivity and specificity in diverse intensive care units of a large academic medical center. Further studies are needed to evaluate the effect of automated prompts that such a system can initiate on the use of lung protective ventilation in patients with acute lung injury.

Refugee health and medical student training.

Griswold, Kim S

2003-10-01

Cultural awareness training is an increasingly important priority within medical curricula. This article describes an academic family practice-community partnership focusing on health care needs of refugees that became the model for a medical school selective on cultural sensitivity training. The monthly Refugee Health Night program featured dinner with preceptors and patients, international sessions on special medical needs of refugees, and actual clinical encounters with patients. Students were not expected to become culturally competent experts but, rather, health care providers sensitive to and appreciative of cultural context, experience, and expectations. We worked with students to develop sensitive methods of inquiry about mental health, especially around issues of war and torture. We used problem-based cases to emphasize primary care continuity and the benefit of establishing trust over time. Over 2 years, 50 students and nearly 300 refugees (more than 73 families) participated. Students reported that their interactions with the refugees provided positive learning experiences, including expanded knowledge of diverse cultures and enhanced skills for overcoming communication barriers. Patients of refugee status were able to have emergent health care needs met in a timely fashion. Providing health care for refugee individuals and families presents many challenges as well as extraordinary opportunities for patients and practitioners to learn from one another.

2016-01-01

Intensive care unit (ICU) patients are at risk of in-ICU morbidities and mortality, making specific systems for identifying at-risk patients a necessity for improving clinical care. This study presents a new method for predicting in-hospital mortality using heart rate variability (HRV) collected from the times of a patient's ICU stay. In this paper, a HRV time series processing based method is proposed for mortality prediction of ICU cardiovascular patients. HRV signals were obtained measuring R-R time intervals. A novel method, named return map, is then developed that reveals useful information from the HRV time series. This study also proposed several features that can be extracted from the return map, including the angle between two vectors, the area of triangles formed by successive points, shortest distance to 45° line and their various combinations. Finally, a thresholding technique is proposed to extract the risk period and to predict mortality. The data used to evaluate the proposed algorithm obtained from 80 cardiovascular ICU patients, from the first 48 h of the first ICU stay of 40 males and 40 females. This study showed that the angle feature has on average a sensitivity of 87.5% (with 12 false alarms), the area feature has on average a sensitivity of 89.58% (with 10 false alarms), the shortest distance feature has on average a sensitivity of 85.42% (with 14 false alarms) and, finally, the combined feature has on average a sensitivity of 92.71% (with seven false alarms). The results showed that the last half an hour before the patient's death is very informative for diagnosing the patient's condition and to save his/her life. These results confirm that it is possible to predict mortality based on the features introduced in this paper, relying on the variations of the HRV dynamic characteristics.

Building on an existing theoretical shared primary care/specialist care framework to (1) develop a unique typology of care for people living with human immunodeficiency virus (HIV) in Ontario, (2) assess sensitivity of the typology by varying typology definitions, and (3) describe characteristics of typology categories. Retrospective population-based observational study from April 1, 2009, to March 31, 2012. A total of 13,480 eligible patients with HIV and receiving publicly funded health care in Ontario. We derived a typology of care by linking patients to usual family physicians and to HIV specialists with five possible patterns of care. Patient and physician characteristics and outpatient visits for HIV-related and non-HIV-related care were used to assess the robustness and characteristics of the typology. Five possible patterns of care were described as low engagement (8.6%), exclusively primary care (52.7%), family physician-dominated comanagement (10.0%), specialist-dominated comanagement (30.5%), and exclusively specialist care (5.2%). Sensitivity analyses demonstrated robustness of typology assignments. Visit patterns varied in ways that conform to typology assignments. We anticipate this typology can be used to assess the impact of care patterns on the quality of primary care for people living with HIV. Copyright © 2015 Elsevier Inc. All rights reserved.

A Monte Carlo Simulation Study of the Reliability of Intraindividual Variability

Estabrook, Ryne; Grimm, Kevin J.; Bowles, Ryan P.

2012-01-01

Recent research has seen intraindividual variability (IIV) become a useful technique to incorporate trial-to-trial variability into many types of psychological studies. IIV as measured by individual standard deviations (ISDs) has shown unique prediction to several types of positive and negative outcomes (Ram, Rabbit, Stollery, & Nesselroade, 2005). One unanswered question regarding measuring intraindividual variability is its reliability and the conditions under which optimal reliability is achieved. Monte Carlo simulation studies were conducted to determine the reliability of the ISD compared to the intraindividual mean. The results indicate that ISDs generally have poor reliability and are sensitive to insufficient measurement occasions, poor test reliability, and unfavorable amounts and distributions of variability in the population. Secondary analysis of psychological data shows that use of individual standard deviations in unfavorable conditions leads to a marked reduction in statistical power, although careful adherence to underlying statistical assumptions allows their use as a basic research tool.

Skin interaction with absorbent hygiene products.

PubMed

Runeman, Bo

2008-01-01

Skin problems due to the use of absorbent hygiene products, such as diapers, incontinence pads, and feminine sanitary articles, are mostly due to climate or chafing discomfort. If these conditions are allowed to prevail, these may develop into an irritant contact dermatitis and eventually superficial skin infections. Skin humidity and aging skin are among the most significant predisposing and aggravating factors for dermatitis development. Improved product design features are believed to explain the decline in observed diaper dermatitis among infants. Where adult incontinence-related skin problems are concerned, it is very important to apply a holistic perspective to understand the influences due to the individual's incontinence level and skin condition, as well as the hygiene and skin care measures provided. Individuals with frail, sensitive skin or with skin diseases may preferably have to use high-quality products, equipped with superabsorbent polymers and water vapor-permeable back sheets, to minimize the risk of skin complications.

A suitable method for the direct measurement of moisture concentrations after humidity/thermal exposure on state of the art epoxy and polyimide resins and their graphite and glass fiber reinforcements was investigated. Methods for the determination of moisture concentration profiles, moisture diffusion modeling and moisture induced chemical changes were examined. Carefully fabricated, precharacterized epoxy and polyimide neat resins and their AS graphite and S glass reinforced composites were exposed to humid conditions using heavy water (D20), at ambient and elevated temperatures. These specimens were fixtured to theoretically limit the D20 permeation to a unidirectional penetration axis. The analytical techniques evaluated were: (1) laser pyrolysis gas chromatography mass spectrometry; (2) solids probe mass spectrometry; (3) laser pyrolysis conventional infrared spectroscopy; and (4) infrared imaging thermovision. The most reproducible and sensitive technique was solids probe mass spectrometry. The fabricated exposed specimens were analyzed for D20 profiling after humidity/thermal conditioning at three exposure time durations.

Definition and management of hypertension among Haitian immigrants: a qualitative study.

Sanon, Marie-Anne; Mohammed, Selina A; McCullagh, Marjorie C

2014-08-01

Hypertension is a major health concern among Haitian immigrants, one of the largest Caribbean immigrant groups in the United States. Yet, little is known about how Hatian immigrants define and manage hypertension. For this qualitative study, face-to-face semi-structured interviews were conducted with 31 Haitian immigrants in Miami Dade County, Florida. Results indicated that most Haitian immigrants used the Haitian Creole word tansyon to represent hypertension. Tansyon was considered as either a normal condition of the human body or a maladi (illness). Both traditional biomedical and alternative approaches were used to manage hypertension. The findings show that how Haitian immigrants defined hypertension shaped their beliefs about its occurrence and the resulting management strategies used. Those who believed tansyon was a normal body condition did not take any management measures. Awareness and understanding of Haitian immigrants' beliefs about and approaches to hypertension management can enhance culturally sensitive care and improve health outcomes.

Haloperidol can induce catalepsy and this drug effect can be conditioned as well as sensitized to contextual cues. We used a paired/unpaired Pavlovian conditioning protocol to establish haloperidol catalepsy conditioned and sensitized responses. Groups of rats were given 10 daily catalepsy tests following administration of vehicle (n=24) or haloperidol (1.0mg/kg) either paired (n=18) or unpaired (n=18) to testing. Subsequently, testing for conditioning was conducted and conditioning and sensitization of catalepsy were observed selectively in the paired group. Immediately following a second test for catalepsy conditioning, the groups were subdivided into 4 vehicle groups, 3 unpaired haloperidol groups and 3 paired haloperidol groups and were given one of three post-trial treatments (vehicle, 0.05mg/kg or 2.0mg/kg apomorphine). One day later the conditioned catalepsy test 3 was carried out and on the next day, a haloperidol challenge test was performed. The post-trial apomorphine treatments had major effects on the paired groups upon both conditioning and the haloperidol challenge test. The low dose apomorphine post-trial treatment enhanced both the conditioned and the haloperidol sensitized catalepsy responses. The high dose apomorphine post-trial treatment eliminated conditioned catalepsy and eliminated the initial acute catalepsy response to haloperidol that was induced in the vehicle control groups. These results demonstrate the sensitivity of conditioned drug cues to modification by increases/decreases in activity of the dopamine system in the immediate post-trial interval after a conditioning trial. This demonstration that post-trial dopaminergic drug treatments can modify conditioned drug behavior has broad implications for conditioned drug effects. Copyright © 2016 Elsevier B.V.

How many referrals to a pediatric orthopaedic hospital specialty clinic are primary care problems?

Hsu, Eric Y; Schwend, Richard M; Julia, Leamon

2012-01-01

Many primary care physicians believe that there are too few pediatric orthopaedic specialists available to meet their patients' needs. However, a recent survey by the Practice Management Committee of the Pediatric Orthopaedic Society of North America found that new referrals were often for cases that could have been managed by primary care practitioners. We wished to determine how many new referral cases seen by pediatric orthopaedic surgeons are in fact conditions that can be readily managed by a primary care physician should he/she chose to do so. We prospectively studied all new referrals to our hospital-based orthopaedic clinic during August 2010. Each new referral was evaluated for whether it met the American Board of Pediatrics criteria for being a condition that could be managed by a primary care pediatrician. Each referral was also evaluated for whether it met the American Academy of Pediatrics Surgery Advisory Panel guidelines recommending referral to an orthopaedic specialist, regardless of whether it is for general orthopaedics or pediatric orthopaedics. On the basis of these criteria, we classified conditions as either a condition manageable by primary care physicians or a condition that should be referred to an orthopaedic surgeon or a pediatric orthopaedic surgeon. We used these guidelines not to identify diagnosis that primary care physicians should treat but, rather, to compare the guideline-delineated referrals with the actual referrals our specialty pediatric orthopaedic clinic received over a period of 1 month. A total of 529 new patient referrals were seen during August 2010. A total of 246 (47%) were considered primary care conditions and 283 (53%) orthopaedic specialty conditions. The most common primary care condition was a nondisplaced phalanx fracture (25/246, 10.1%) and the most common specialty condition was a displaced single-bone upper extremity fracture needing reduction (36/283, 13%). Only 77 (14.6%) of the total cases met the strict American Academy of Pediatrics Surgery Advisory Panel guidelines recommending referral to pediatric orthopaedics, with scoliosis being the most frequent condition. For 38 (7.2%) cases, surgical treatment was required or recommended. Patient age, referral source, or type of insurance did not influence whether the condition was a primary care or a specialty care case. A total of 134 (25%) cases were referred without having an initial diagnosis made by the referring clinician. These patients were more likely to have been referred from a primary care practitioner than from a tertiary care practitioner whether the diagnosis eventually made was considered to be a primary care condition (P=0.03; relative risk, 1.9; 95% confidence interval, 96-3.86). Almost half of all new referrals to a tertiary pediatric orthopaedic clinic were for conditions considered to be manageable by primary care physicians should they chose to do so. This has implications for pediatric orthopaedic workforce availability, reimbursement under the Affordable Care Act, and pediatric musculoskeletal training needs for providers of primary care.

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, minimise costs to the health budget, and maximise health care quality.

Background Deprivation usually encompasses material, social, and health components. It has been shown to be associated with greater risks of developing chronic health conditions and of worse outcome in multimorbidity. The DipCare questionnaire, an instrument developed and validated in Switzerland for use in primary care, identifies patients subject to potentially higher levels of deprivation. Objectives To identifying determinants of the material, social, and health profiles associated with deprivation in a sample of multimorbid, primary care patients, and thus set priorities in screening for deprivation in this population. Design Secondary analysis from a nationwide cross-sectional study in Switzerland. Participants A random sample of 886 adult patients suffering from at least three chronic health conditions. Main measures The outcomes of interest were the patients’ levels of deprivation as measured using the DipCare questionnaire. Classification And Regression Tree analysis identified the independent variables that separated the examined population into groups with increasing deprivation scores. Finally, a sensitivity analysis (multivariate regression) confirmed the robustness of our results. Key results Being aged under 64 years old was associated with higher overall, material, and health deprivation; being aged over 77 years old was associated with higher social deprivation. Other variables associated with deprivation were the level of education, marital status, and the presence of depression or chronic pain. Conclusion Specific profiles, such as being younger, were associated with higher levels of overall, material, and health deprivation in multimorbid patients. In contrast, patients over 77 years old reported higher levels of social deprivation. Furthermore, chronic pain and depression added to the score for health deprivation. It is important that GPs consider the possibility of deprivation in these multimorbid patients and are able to identify it, both in order to encourage treatment adherence and limit any forgoing of care for financial reasons.

The adsorption of charged biomolecules on a substrate will trigger a self-induced electric potential field that could deflect microcantilever biosensors in the nanometer regime. The paper is devoted to a multiscale characterization of the piezoelectric coefficient of double-stranded DNA (dsDNA) films with microscopic attractive interactions in multivalence salt solutions, which has a close relationship with biosensor signals. First, two different analytical models of cantilever deflections based on macroscopic piezoelectric theories or mesoscopic liquid crystal theories were combined in the sense of equivalent deformation in order to bridge the relation between the macroscopic piezoelectric coefficient of an adsorbate film and the sensitivity of its microstructure to surrounding conditions. Second, two interaction potentials of the free energy for repulsion-dominated DNA films in NaCl solution or attraction-repulsion-coexisted DNA films in multivalent salt solutions were used to compare the piezoelectric effect and the resultant cantilever deformation at various packing conditions, such as different packing density, various nucleotide numbers and two packing technologies, i.e. nano-grafting or self-assembling technology. The variational tendency of microcantilever deflections predicted by the present multiscale analytical model agrees well with the related DNA-mirocantilever experiments. Negative piezoelectric coefficient of dsDNA film exists in multivalent salt solutions, and its distinctive size effect with different packing densities and nucleotide numbers provides us with an opportunity to obtain a more sensitive microcantilever sensor by careful control of packing conditions.

After extreme dry (wet) summers or years, pollen production of different taxa may decrease (increase) substantially. Accordingly, studying effects of current and past meteorological conditions on current pollen concentrations for different taxa have of major importance. The purpose of this study is separating the weight of current and past weather conditions influencing current pollen productions of three taxa. Two procedures, namely multiple correlations and factor analysis with special transformation are used. The 11-year (1997-2007) data sets include daily pollen counts of Ambrosia (ragweed), Poaceae (grasses) and Populus (poplar), as well as daily values of four climate variables (temperature, relative humidity, global solar flux and precipitation). Multiple correlations of daily pollen counts with simultaneous values of daily meteorological variables do not show annual course for Ambrosia, but do show definite trends for Populus and Poaceae. Results received using the two methods revealed characteristic similarities. For all the three taxa, the continental rainfall peak and additional local showers in the growing season can strengthen the weight of the current meteorological elements. However, due to the precipitation, big amount of water can be stored in the soil contributing to the effect of the past climate elements during dry periods. Higher climate sensitivity (especially water sensitivity) of the herbaceous taxa ( Ambrosia and Poaceae) can be definitely established compared to the arboreal Populus. Separation of the weight of the current and past weather conditions for different taxa involves practical importance both for health care and agricultural production.

Dehydration is a common condition and frequent cause of hospitalization in older people, despite the caregiver's high attention in attempt to avoid its occurrence. In this study, various physical signs were examined as clinical signs of dehydration in elderly. A prospective observational study was conducted in an acute care teaching hospital. Consecutive elderly patients who were admitted to the Department of Medicine were evaluated. Dehydration was defined as a calculated serum osmolality above 295 mOsm/L. The patients diagnosed as dehydrated or not dehydrated were observed for physical signs of dehydration. Data of blood and urine chemistry analysis were also compared between the two groups. A total of 27 elderly patients admitted with acute medical conditions were included in this study. For the physical signs, dry axilla had moderate sensitivity (44%) and excellent specificity (89%) to detect dehydration. Sunken eyes and delayed capillary refill time also showed relatively good specificity (83%). For laboratory data, the mean concentrations of serum sodium of the dehydrated group (146 mEq/L) was significantly higher (p<0.01) than those of the non-dehydrated group (134 mEq/L). Physical signs of dehydration in elderly showed relatively good specificity but poor sensitivity. The evaluation of the axillary moisture could help assess dehydration as well as laboratory data analysis such as serum sodium concentration.

A novel mixing approach was utilized with a highly sensitive chemiluminescence (CL) method to determine the total phenolic content (TPC) in honey samples using an acidic potassium permanganate-formaldehyde system. The mixing approach was based on exploiting the mixing efficiency of nanodroplets generated in a microfluidic platform. Careful optimization of the instrument setup and various experimental conditions were employed to obtain excellent sensitivity. The mixing efficiency of the droplets was compared with the CL signal intensity obtained using the common serpentine chip design, with both approaches using at a total flow rate of 15 μl min -1 ; the results showed that the nanodroplets provided 600% higher CL signal intensity at this low flow rate. Using the optimum conditions, calibration equations, limits of detection (LOD) and limits of quantification (LOQ) for gallic acid (GA), caffeic acid (CA), kaempferol (KAM), quercetin (QRC) and catechin (CAT) were obtained. The LOD ranged from 6.2 ppb for CA to 11.0 ppb for QRC. Finally, the method was applied for the determination of TPC in several local and commercial honey samples.

A reusable and mediator-free cholesterol biosensor based on cholesterol oxidase (ChOx) was fabricated based on self-assembled monolayer (SAM) of thioglycolic acid (TGA) (covalent enzyme immobilization by dropping method) using bio-chips. Cholesterol was detected with modified bio-chip (Gold/Thioglycolic-acid/Cholesterol-oxidase i.e., Au/TGA/ChOx) by reliable cyclic voltammetric (CV) technique at room conditions. The Au/TGA/ChOx modified bio-chip sensor demonstrates good linearity (1.0 nM to 1.0 mM; R = 0.9935), low-detection limit (∼0.42 nM, SNR∼3), and higher sensitivity (∼74.3 µAµM−1cm−2), lowest-small sample volume (50.0 μL), good stability, and reproducibility. To the best of our knowledge, this is the first statement with a very high sensitivity, low-detection limit, and low-sample volumes are required for cholesterol biosensor using Au/TGA/ChOx-chips assembly. The result of this facile approach was investigated for the biomedical applications for real samples at room conditions with significant assembly (Au/TGA/ChOx) towards the development of selected cholesterol biosensors, which can offer analytical access to a large group of enzymes for wide range of biomedical applications in health-care fields.

To examine multiple chronic conditions and related health care expenditures in children. Retrospective cohort study of all dependents of Mayo Clinic employees aged 0-17 on Jan 1, 2004 with continuous health benefits coverage for 4 years (N=14,727). Chronic conditions, health care utilization, and associated expenditures were obtained from medical and pharmacy claims. The most prevalent chronic conditions were asthma/chronic obstructive pulmonary disease (12%), allergic rhinitis (11%), and behavior problems (9%). The most costly conditions were congenital anomalies, asthma/chronic obstructive pulmonary disease, and behavior problems ($9602, $4335, and $5378 annual cost per child, respectively). Annual health care expenditures increased substantially with the number of chronic conditions, and a small proportion of children with multiple chronic conditions accounted for a large proportion of health care costs. In addition, those with multiple chronic conditions were more likely to persist in the top 10th percentile spender group in year-to-year spending. Children with multiple chronic conditions accounted for a large proportion of health care expenditures. These children were also likely to persist as high spenders in the 4-year time frame. Further research into effective ways to manage the health care delivery for children with multiple chronic conditions is needed. © The Author(s) 2014.

Adapting chronic care models for diabetes care delivery in low-and-middle-income countries: A review

Ku, Grace Marie V; Kegels, Guy

2015-01-01

A contextual review of models for chronic care was done to develop a context-adapted chronic care model-based service delivery model for chronic conditions including diabetes. The Philippines was used as the setting of a low-to-middle-income country. A context-based narrative review of existing models for chronic care was conducted. A situational analysis was done at the grassroots level, involving the leaders and members of the community, the patients, the local health system and the healthcare providers. A second analysis making use of certain organizational theories was done to explore on improving feasibility and acceptability of organizing care for chronic conditions. The analyses indicated that care for chronic conditions may be introduced, considering the needs of people with diabetes in particular and the community in general as recipients of care, and the issues and factors that may affect the healthcare workers and the health system as providers of this care. The context-adapted chronic care model-based service delivery model was constructed accordingly. Key features are: incorporation of chronic care in the health system’s services; assimilation of chronic care delivery with the other responsibilities of the healthcare workers but with redistribution of certain tasks; and ensuring that the recipients of care experience the whole spectrum of basic chronic care that includes education and promotion in the general population, risk identification, screening, counseling including self-care development, and clinical management of the chronic condition and any co-morbidities, regardless of level of control of the condition. This way, low-to-middle income countries can introduce and improve care for chronic conditions without entailing much additional demand on their limited resources. PMID:25987954

Low-cost, robust, and reusable continuous glucose monitoring systems that can provide quantitative measurements at point-of-care settings is an unmet medical need. Optical glucose sensors require complex and time-consuming fabrication processes, and their readouts are not practical for quantitative analyses. Here, a wearable contact lens optical sensor was created for the continuous quantification of glucose at physiological conditions, simplifying the fabrication process and facilitating smartphone readouts. A photonic microstructure having a periodicity of 1.6 μm was printed on a glucose-selective hydrogel film functionalized with phenylboronic acid. Upon binding with glucose, the microstructure volume swelled, which modulated the periodicity constant. The resulting change in the Bragg diffraction modulated the space between zero- and first-order spots. A correlation was established between the periodicity constant and glucose concentration within 0-50 mM. The sensitivity of the sensor was 12 nm mM -1 , and the saturation response time was less than 30 min. The sensor was integrated with commercial contact lenses and utilized for continuous glucose monitoring using smartphone camera readouts. The reflected power of the first-order diffraction was measured via a smartphone application and correlated to the glucose concentrations. A short response time of 3 s and a saturation time of 4 min was achieved in the continuous monitoring mode. Glucose-sensitive photonic microstructures may have applications in point-of-care continuous monitoring devices and diagnostics at home settings.

In the present study, we explored family caregivers' experiences in providing end-of-life care for terminally ill South Asian immigrants. We employed qualitative methods and. in-depth interviews were conducted with seven family caregivers living in Nova Scotia, Canada. Interview data were validated, coded and organized for themes. Three major themes identified in the data illustrated (a) how South Asian caregivers experienced clashes between biomedical and ethno-cultural realms of care that led to cultural insensitivity, (b) how family members acted as mediators, and (c) how communication issues that challenged cultural sensitivity were handled. Findings provide directions for culturally sensitive end-of-life care planning.

Rapid, simple, and cost-effective diagnostics are needed to improve healthcare at the point of care (POC). However, the most widely used POC diagnostic, the lateral flow immunoassay (LFA), is ∼1000-times less sensitive and has a smaller analytical range than laboratory tests, requiring a confirmatory test to establish truly negative results. Here, a rational and systematic strategy is used to design the LFA contrast label (i.e., gold nanoparticles) to improve the analytical sensitivity, analytical detection range, and antigen quantification of LFAs. Specifically, we discovered that the size (30, 60, or 100 nm) of the gold nanoparticles is a main contributor to the LFA analytical performance through both the degree of receptor interaction and the ultimate visual or thermal contrast signals. Using the optimal LFA design, we demonstrated the ability to improve the analytical sensitivity by 256-fold and expand the analytical detection range from 3 log 10 to 6 log 10 for diagnosing patients with inflammatory conditions by measuring C-reactive protein. This work demonstrates that, with appropriate design of the contrast label, a simple and commonly used diagnostic technology can compete with more expensive state-of-the-art laboratory tests.

Functional roles of the pepper RING finger protein gene, CaRING1, in abscisic acid signaling and dehydration tolerance.

Plants are constantly exposed to a variety of biotic and abiotic stresses, which include pathogens and conditions of high salinity, low temperature, and drought. Abscisic acid (ABA) is a major plant hormone involved in signal transduction pathways that mediate the defense response of plants to abiotic stress. Previously, we isolated Ring finger protein gene (CaRING1) from pepper (Capsicum annuum), which is associated with resistance to bacterial pathogens, accompanied by hypersensitive cell death. Here, we report a new function of the CaRING1 gene product in the ABA-mediated defense responses of plants to dehydration stress. The expression of the CaRING1 gene was induced in pepper leaves treated with ABA or exposed to dehydration or NaCl. Virus-induced gene silencing of CaRING1 in pepper plants exhibited low degree of ABA-induced stomatal closure and high levels of transpirational water loss in dehydrated leaves. These led to be more vulnerable to dehydration stress in CaRING1-silenced pepper than in the control pepper, accompanied by reduction of ABA-regulated gene expression and low accumulation of ABA and H2O2. In contrast, CaRING1-overexpressing transgenic plants showed enhanced sensitivity to ABA during the seedling growth and establishment. These plants were also more tolerant to dehydration stress than the wild-type plants because of high ABA accumulation, enhanced stomatal closure and increased expression of stress-responsive genes. Together, these results suggest that the CaRING1 acts as positive factor for dehydration tolerance in Arabidopsis by modulating ABA biosynthesis and ABA-mediated stomatal closing and gene expression.

Effects of Varenicline on Ethanol-Induced Conditioned Place Preference, Locomotor Stimulation, and Sensitization

Gubner, Noah R.; McKinnon, Carrie S.; Phillips, Tamara J.

2014-01-01

Background Varenicline, a partial nicotinic acetylcholine receptor (nAChR) agonist, is a promising new drug for the treatment of alcohol (ethanol) dependence. Varenicline has been approved by the Food and Drug Administration as a smoking cessation therapeutic and has also been found to reduce ethanol consumption in humans and animal models of alcohol use. The current studies examined the hypotheses that varenicline attenuates the stimulant and sensitizing effects of ethanol, and reduces the motivational effects of ethanol-associated cues. The goal was to determine if these effects of varenicline contribute to its pharmacotherapeutic effects for alcohol dependence. In addition, effects of varenicline on acute stimulation and/or on the acquisition of sensitization would suggest a role for nAChR involvement in these effects of ethanol. Methods Dose-dependent effects of varenicline on the expression of ethanol-induced conditioned place preference (CPP), locomotor activation, and behavioral sensitization were examined. These measures model motivational effects of ethanol-associated cues, euphoric or stimulatory effects of ethanol, and ethanol-induced neuroadaptation. All studies used DBA/2J mice, an inbred strain with high sensitivity to these ethanol-related effects. Results Varenicline did not significantly attenuate the expression of ethanol-induced CPP. Varenicline reduced locomotor activity and had the most pronounced effect in the presence of ethanol, with the largest effect on acute ethanol-induced locomotor stimulation and a trend for varenicline to attenuate the expression of ethanol-induced sensitization. Conclusions Because varenicline did not attenuate the expression of ethanol-induced CPP, it may not be effective at reducing the motivational effects of ethanol-associated cues. This outcome suggests that reductions in the motivational effects of ethanol-associated cues may not be involved in how varenicline reduces ethanol consumption. However, varenicline did have effects on locomotor behavior and significantly attenuated acute ethanol-induced locomotor stimulation. In humans who drink while taking varenicline, it might similarly reduce stimulant responses and have an impact on continued drinking. General sedative effects in such individuals should be carefully considered. PMID:25581658

Severe Mental Illness (SMI) encompasses a range of chronic conditions including schizophrenia, bipolar disorder and psychoses. Patients with SMI often require inpatient psychiatric care. Despite equity being a key objective in the English National Health Service (NHS) and in many other health care systems worldwide, little is known about the socio-economic equity of hospital care utilisation for patients with SMI and how it has changed over time. This analysis seeks to address that gap in the evidence base. We exploit a five-year (2006-2010) panel dataset of admission rates at small area level (n=162,410). The choice of control variables was informed by a systematic literature search. To assess changes in socio-economic equity of utilisation, OLS-based standardisation was first used to conduct analysis of discrete deprivation groups. Geographical inequity was then illustrated by plotting standardised and crude admission rates at local purchaser level. Lastly, formal statistical tests for changes in socio-economic equity of utilisation were applied to a continuous measure of deprivation using pooled negative binomial regression analysis, adjusting for a range of risk factors. Our results suggest that one additional percentage point of area income deprivation is associated with a 1.5% (p<0.001) increase in admissions for SMI after controlling for population size, age, sex, prevalence of SMI in the local population, as well as other need and supply factors. This finding is robust to sensitivity analyses, suggesting that a pro-poor inequality in utilisation exists for SMI-related inpatient services. One possible explanation is that the supply or quality of primary, community or social care for people with mental health problems is suboptimal in deprived areas. Although there is some evidence that inequity has reduced over time, the changes are small and not always robust to sensitivity analyses. Copyright © 2014 The Authors. Published by Elsevier Ltd..

The fast-paced environment of hospitals contributes to communication failures between health care providers while impacting patient care and patient flow. An effective mechanism for sharing patients' discharge information with health care team members is required to improve patient throughput. The communication of a patient's discharge plan was identified as crucial in alleviating patient flow delays at a tertiary care, academic medical center. By identifying the patients who were expected to be discharged the following day, the health care team could initiate discharge preparations in advance to improve patient care and patient flow. The patients' electronic medical record served to convey dynamic information regarding the patients' discharge status to the health care team via conditional discharge orders. Two neurosciences units piloted a conditional discharge order initiative. Conditional discharge orders were designed in the electronic medical record so that the conditions for discharge were listed in a dropdown menu. The health care team was trained on the conditional discharge order protocol, including when to write them, how to find them in the patients' electronic medical record, and what actions should be prompted by these orders. On average, 24% of the patients discharged had conditional discharge orders written the day before discharge. The average discharge time for patients with conditional discharge orders decreased by 83 minutes (0.06 day) from baseline. Qualitatively, the health care team reported improved workflows with conditional orders. The conditional discharge orders allowed physicians to communicate pending discharges electronically to the multidisciplinary team. The initiative positively impacted patient discharge times and workflows.

To advance research on depression communication and treatment by comparing assessments of communication about depression from patient report, clinician report, and chart review to assessments from transcripts. One hundred sixty-four primary care visits from seven health care systems (2010-2011). Presence or absence of discussion about depressive symptoms, treatment recommendations, and follow-up was measured using patient and clinician postvisit questionnaires, chart review, and coding of audio transcripts. Sensitivity and specificity of indirect measures compared to transcripts were calculated. Patient report was sensitive for mood (83 percent) and sleep (83 percent) but not suicide (55 percent). Patient report was specific for suicide (86 percent) but not for other symptoms (44-75 percent). Clinician report was sensitive for all symptoms (83-98 percent) and specific for sleep, memory, and suicide (80-87 percent), but not for other symptoms (45-48 percent). Chart review was not sensitive for symptoms (50-73 percent), but it was specific for sleep, memory, and suicide (88-96 percent). All indirect measures had low sensitivity for treatment recommendations (patient report: 24-42 percent, clinician report 38-50 percent, chart review 49-67 percent) but high specificity (89-96 percent). For definite follow-up plans, all three indirect measures were sensitive (82-96 percent) but not specific (40-57 percent). Clinician report and chart review generally had the most favorable sensitivity and specificity for measuring discussion of depressive symptoms and treatment recommendations, respectively. © Health Research and Educational Trust.

To compare the accuracy of and factors affecting the accuracy of self-reported fall-related injuries (SFRIs) with those of administratively obtained FRIs (AFRIs). Retrospective observational study SETTING: United States PARTICIPANTS: Fee-for-service Medicare beneficiaries aged 65 and older (N=47,215). We used 24-month self-report recall data from 2000-2012 Health and Retirement Study data to identify SFRIs and linked inpatient, outpatient, and ambulatory Medicare data to identify AFRIs. Sensitivity and specificity were assessed, with AFRIs defined using the University of California at Los Angeles/RAND algorithm as the criterion standard. Logistic regression models were used to identify sociodemographic and health predictors of sensitivity. Overall sensitivity and specificity were 28% and 92%. Sensitivity was greater for the oldest adults (38%), women (34%), those with more functional limitations (47%), and those with a prior fall (38%). In adjusted results, several participant factors (being female, being white, poor functional status, depression, prior falls) were modestly associated with better sensitivity and specificity. Injury severity (requiring hospital care) most substantively improved SFRI sensitivity (73%). An overwhelming 72% of individuals who received Medicare-reimbursed health care for FRIs failed to report a fall injury when asked. Future efforts to address underreporting in primary care of nonwhite and healthier older adults are critical to improve preventive efforts. Redesigned questions-for example, that address stigma of attributing injury to falling-may improve sensitivity. © 2018, Copyright the Authors Journal compilation © 2018, The American Geriatrics Society.

As foreigners live in and visit Turkey for various reasons, it is essential to provide culturally appropriate health care. This study was conducted to determine the relationship between cultural sensitivity and assertiveness in university nursing students. This descriptive, cross-sectional study was conducted at two universities in the cities of Kilis and Elazığ, Turkey. The study sample consisted of 444 nursing students. Data collection tools included a questionnaire about participant sociodemographic characteristics, Chen and Starosta's Intercultural Sensitivity Scale, and the Rathus Assertiveness Scale. The mean age of participants was 21.09 years. Most students (71.6%) were female and 34.7% of the students stayed at the hostel. Of the students, 44.4%, 27.5%, and 28.2% attended were the second-, third-, and fourth-year students, respectively. Participants were asked about problems related to caring for patients who speak different languages. The mean score for the Intercultural Sensitivity Scale was 89.42 ± 13.55 and the total score for all students for the Assertiveness Scale was 112.64 ± 15.61. We identified a positive relationship between total scores for the Intercultural Sensitivity Scale and the Assertiveness Scale ( p < .001). There was relationship between cultural sensitivity and gender and want to work overseas; assertiveness and year of nursing education and want to work overseas. Nursing students at both schools had a moderate level of cultural sensitivity and assertiveness. It has been determined that as assertiveness level of the students increased, intercultural sensitivity of them also increased. Consequently, it is concluded that training as assertive and self-confident individuals during the nursing education of students has a contribution to making patient-specific and culture-sensitive care.

Feeding conditions modify sensitivity to indirect- and direct-acting dopamine receptor agonists as well as the development of sensitization to these drugs. This study examined whether feeding condition affects acute sensitivity to apomorphine-induced yawning or changes in sensitivity that occur over repeated drug administration. Quinpirole-induced yawning was also evaluated to see whether sensitization to apomorphine confers cross-sensitization to quinpirole. Drug-induced yawning was measured in different groups of male Sprague Dawley rats (n = 6/group) eating high (34.3%) fat or standard (5.7% fat) chow. Five weeks of eating high-fat chow rendered otherwise drug-naïve rats more sensitive to apomorphine- (0.01-1.0 mg/kg, i.p.) and quinpirole- (0.0032-0.32 mg/kg, i.p.) induced yawning, compared with rats eating standard chow. In other rats, tested weekly with apomorphine, sensitivity to apomorphine-induced yawning increased (sensitization) similarly in rats with free access to standard or high-fat chow; conditioning to the testing environment appeared to contribute to increased yawning in both groups of rats. Food restriction decreased sensitivity to apomorphine-induced yawning across five weekly tests. Rats with free access to standard or high-fat chow and sensitized to apomorphine were cross-sensitized to quinpirole-induced yawning. The hypothermic effects of apomorphine and quinpirole were not different regardless of drug history or feeding condition. Eating high-fat chow or restricting access to food alters sensitivity to direct-acting dopamine receptor agonists (apomorphine, quinpirole), although the relative contribution of drug history and dietary conditions to sensitivity changes appears to vary among agonists.

Malnutrition is a prevalent condition related to adverse outcomes in older people. Our aim was to compare the diagnostic capacity of the malnutrition criteria of the European Society of Parenteral and Enteral Nutrition (ESPEN) with other classical diagnostic tools. Cohort study of 102 consecutive in-patients ≥70 years admitted for postacute rehabilitation. Patients were considered malnourished if their Mini-Nutritional Assessment-Short Form (MNA-SF) score was ≤11 and serum albumin <3 mg/dL or MNA-SF ≤ 11, serum albumin <3 mg/dL, and usual clinical signs and symptoms of malnutrition. Sensitivity, specificity, positive and negative predictive values, accuracy likelihood ratios, and kappa values were calculated for both methods: and compared with ESPEN consensus. Of 102 eligible in-patients, 88 fulfilled inclusion criteria and were identified as "at risk" by MNA-SF. Malnutrition diagnosis was confirmed in 11.6% and 10.5% of the patients using classical methods,whereas 19.3% were malnourished according to the ESPEN criteria. Combined with low albumin levels, the diagnosis showed 57.9% sensitivity, 64.5% specificity, 85.9% negative predictive value,0.63 accuracy (fair validity, low range), and kappa index of 0.163 (poor ESPEN agreement). The combination of MNA-SF, low albumin, and clinical malnutrition showed 52.6% sensitivity, 88.3% specificity, 88.3%negative predictive value, and 0.82 accuracy (fair validity, low range), and kappa index of 0.43 (fair ESPEN agreement). Malnutrition was almost twice as prevalent when diagnosed by the ESPEN consensus, compared to classical assessment methods: Classical methods: showed fair validity and poor agreement with the ESPEN consensus in assessing malnutrition in geriatric postacute care.

Continuous glucose monitoring for patients with diabetes is of paramount importance to avoid severe health conditions resulting from hypoglycemia or hyperglycemia. Most available methods require an invasive setup and a health care professional. Handheld devices available on the market also require finger pricking for every measurement and do not provide continuous monitoring. Hence, continuous glucose monitoring from human tears using a glucose sensor embedded in a contact lens has been considered as a suitable option. However, the glucose concentration in human tears is very low in comparison with the blood glucose level (1/10-1/40 concentration). We propose a sensor that solves the sensitivity problem in a new way, is flexible, and is constructed onto the oxygen permeable contact lens material. To achieve such sensitivity while maintaining a small sensor footprint suitable for placement in a contact lens, we increased the active electrode area by using three-dimensional (3-D) electrode micropatterning. Fully flexible 3-D electrodes were realized utilizing ordered arrays of pillars with different shapes and heights. We successfully fabricated square and cylindrical pillars with different height (50, 100, and 200 μm) and uniform metal coverage to realize sensor electrodes. The increased surface area produces high amperometric current that increases sensor sensitivity up to 300% using 200 μm tall square pillars. The sensitivity improvement closely follows the improvement in the surface area of the electrode. The proposed flexible glucose sensors with 3-D microstructure electrodes are more sensitive to lower glucose concentrations and generate higher current signal than conventional glucose sensors. © 2011 Diabetes Technology Society.

Measuring the face-sensitive N170 with a gaming EEG system: A validation study.

The N170 is a "face-sensitive" event-related potential (ERP) that occurs at around 170ms over occipito-temporal brain regions. The N170's potential to provide insight into the neural processing of faces in certain populations (e.g., children and adults with cognitive impairments) is limited by its measurement in scientific laboratories that can appear threatening to some people. The advent of cheap, easy-to-use portable gaming EEG systems provides an opportunity to record EEG in new contexts and populations. This study tested the validity of the face-sensitive N170 ERP measured with an adapted commercial EEG system (the Emotiv EPOC) that is used at home by gamers. The N170 recorded through both the gaming EEG system and the research EEG system exhibited face-sensitivity, with larger mean amplitudes in response to the face stimuli than the non-face stimuli, and a delayed N170 peak in response to face inversion. The EPOC system produced very similar N170 ERPs to a research-grade Neuroscan system, and was capable of recording face-sensitivity in the N170, validating its use as research tool in this arena. This opens new possibilities for measuring the face-sensitive N170 ERP in people who cannot travel to a traditional ERP laboratory (e.g., elderly people in care), who cannot tolerate laboratory conditions (e.g., people with autism), or who need to be tested in situ for practical or experimental reasons (e.g., children in schools).

Re-exposure to conditioned drug stimuli triggers re-consolidation processes. In the present study post-trial apomorphine treatments were administered in order to interact with the re-consolidation of an apomorphine conditioned/sensitized locomotor response. A low (0.05 mg/kg) and a high (2.0mg/kg) dose were used to inhibit or to enhance dopamine activity, respectively. Initially, groups received 5 daily apomorphine (2.0mg/kg)/vehicle treatments either paired or unpaired to open-field placement. The paired treatments generated a progressive locomotor response. Subsequently, all groups received a 5 min non-drug test for conditioning and a conditioned locomotor response was observed in the paired group. The groups received another apomorphine (2.0mg/kg)/vehicle treatment as a re-induction treatment. At this stage the post-trial protocol was initiated. One set of paired, unpaired and vehicle groups were given a low dose of apomorphine (0.05 mg/kg) post-trial; another set received a high dose of apomorphine (2.0mg/kg) post-trial. The remaining group set received vehicle post-trial. The low dose post-trial treatment eliminated the conditioned and sensitized locomotor response and the high dose post-trial treatment enhanced the conditioned and sensitized locomotor response. The efficacy of the post-trial apomorphine treatments to modify the conditioned and the sensitized response after a brief non-drug exposure to test cues supports the proposition that exteroceptive cues control conditioning and sensitization and that the interoceptive drug cues make little or no associational contribution to apomorphine conditioning and sensitization. In addition, the findings point to the importance of dopamine activation in both the acquisition and re-consolidation of conditioning processes. Copyright © 2012 Elsevier B.V. All rights reserved.

This paper presents the development of an extremely sensitive and selective acetone sensor prototype which can be used as a platform for non-invasive diabetes detection through exhaled human breath. The miniaturized sensors were produced in high yield with the use of standard microfabrication processes. The sensors were based on a heterostructure composed of MoO 3 and nano-porous silicon (NPS). Features like acetone selective, enhanced sensor response and 0.5 ppm detection limit were observed upon introduction of MoO 3 on the NPS. The sensors were found to be repeatable and stable for almost 1 year, as tested under humid conditions at room temperature. It was inferred that the interface resistance of MoO 3 and NPS played a key role in the sensing mechanism. With the use of breath analysis and lab-on-chip, medical diagnosis procedures can be simplified and provide solutions for point-of-care testing.

Novel fluorimetric assay of trace analysis of epinephrine in human serum

2009-12-01

A simple, rapid, and sensitive spectrofluorimetric technique for the microdetermination of epinephrine in human serum is described. The investigation shows that trace amounts of epinephrine, antidepressant of clinical importance, can be determined without the conventional derivatization or use of fluorophores by diazotization. The method is based on the optimization of experimental parameters, such as pH, temperature, careful selection of excitation and emission wavelengths and on the use of anionic surfactant, sodium dodecyl sulfate (SDS), to enhance sensitivity. The measurement was carried out at 360 nm with excitation at 286 nm. Under the optimum conditions, a linear relationship was obtained between the fluorescence intensity and epinephrine concentration in the range of 0.10 and 1.0 μg/mL; the correlation coefficient and detection limit are 0.9953 and 0.05 μg/mL, respectively. Recovery tests indicated an efficiency of 95.5-98.7% by using known amounts of epinephrine spiked with human serum.

Analysis of retinal fundus images is essential for physicians, optometrists and ophthalmologists in the diagnosis, care and treatment of patients. The first step of almost all forms of automated fundus analysis begins with the segmentation and subtraction of the retinal vasculature, while analysis of that same structure can aid in the diagnosis of certain retinal and cardiovascular conditions, such as diabetes or stroke. This paper investigates the use of a Convolutional Neural Network as a multi-channel classifier of retinal vessels using DRIVE, a database of fundus images. The result of the network with the application of a confidence threshold was slightly below the 2nd observer and gold standard, with an accuracy of 0.9419 and ROC of 0.9707. The output of the network with on post-processing boasted the highest sensitivity found in the literature with a score of 0.9568 and a good ROC score of 0.9689. The high sensitivity of the system makes it suitable for longitudinal morphology assessments, disease detection and other similar tasks.

Among the clinically relevant pain conditions, pain in the musculoskeletal system is most frequent. This article reports extensive epidemiological data on musculoskeletal system pain in Germany and worldwide. Since back pain is most frequent, the diagnostics and therapeutic algorithms of acute, recurring, and chronic lower back pain in Germany will be particularly addressed. The importance of the physiologic-organic, the cognitive-emotional, the behavioral, and the social level to diagnostics and treatment will be discussed. We will also focus on osteoarthritic pain and address its epidemiology, clinical importance, and significance for the health care system. This article will list some reasons why the musculoskeletal system in particular is frequently the site of chronic pain. The authors believe that these reasons are to be sought in the complex structures of the musculoskeletal system; in the particular sensitivity of the deep somatic nociceptive system for long-term sensitization processes, as well as the ensuing nervous system reactions; and in the interactions between the nervous and immune systems. The article will give some insights into the research carried out on this topic in Germany.

Malaria rapid diagnostic tests (MRDTs) are quick and easy to perform and useful for diagnosing malaria in primary health care settings. In South Africa most malaria infections are due to Plasmodium falciparurrm, and HRPII-based MRDTs have been used since 2001. Previous studies in Africa showed variability in sensitivity and specificity of HRPII-based MRDTs; hence, we conducted a field evaluation in Limpopo province to determine the accuracy of the MRDT currently used in public sector clinics and hospitals. A cross-sectional observational study was conducted to determine the sensitivity and specificity of an ICT Pf MRDT. We tested 405 patients with fever with ICT Pf MRDT and compared the results with blood film microscopy (the gold standard). RESULTS. The overall sensitivity of the ICT Pf MRDT was 99.48% (95% confidence interval (CI) 96.17-100%), while specificity was 96.26% (95% CI 94.7-100%). The positive predictive value of the test was 98.48 (99% CI 98.41-100%), and the negative predictive value was 99.52% (95% CI 96.47-100%). The ICT Pf MRDT is an appropriate test to use in the field in South Africa where laboratory facilities are not available. It has a high degree of sensitivity and acceptable level of specificity in accordance with the World Health Organization criteria. However, sensitivity of MRDT at low levels of parasitaemia (<100 parasites/microl of blood) in field conditions must still be established.

Children with potentially severe health conditions such as cerebral palsy (CP) are at risk for unmet health care needs. We sought to determine whether children with CP had significantly greater unmet health care needs than children with other special health care needs (SHCN), and whether conditions associated with CP increased the odds of unmet health care needs. We analyzed data from the National Survey of Children with Special Health Care Needs, 2005-2006, using multivariate logistic regression to calculate the adjusted odds of children with CP having one or more unmet health care needs compared to children with other SHCN. We also determined the association of CP-related conditions with unmet health care needs in children with CP. After weighting to national averages, our sample represented 178,536 children with CP (1.9%), and 9,236,794 with children with other SHCN (98.1%). Although having CP increased the odds that children had unmet health care needs (OR = 1.46, 95% CI [1.07-1.99]), the presence of a "severe" health condition weakened the association. Gastrointestinal problems and emotional problems increased the odds that children with CP would have unmet health care needs above that of children without the associated conditions (p ≤ .01). Children with CP are similar to children with other SHCN and may benefit from collaborative programs targeting severe chronic conditions. However, children with CP and associated conditions have increased odds of unmet health care needs in comparison to children without those problems. Copyright © 2011 Elsevier Ltd.

Childbirth is a leading reason for hospital admission in the USA, and most labour care is provided by registered nurses under physician or midwife supervision in a nurse-managed care model. Yet, there are no validated nurse-sensitive quality measures for maternity care. We aimed to engage primary stakeholders of maternity care in identifying the aspects of nursing care during labour and birth they believe influence birth outcomes, and how these aspects of care might be measured. This qualitative study used 15 focus groups to explore perceptions of 73 nurses, 23 new mothers and 9 physicians regarding important aspects of care. Transcripts were analysed thematically. Participants in the final six focus groups were also asked whether or not they thought each of five existing perinatal quality measures were nurse-sensitive. Nurses, new mothers and physicians identified nurses' support of and advocacy for women as important to birth outcomes. Support and advocacy actions included keeping women and their family members informed, being present with women, setting the emotional tone, knowing and advocating for women's wishes and avoiding caesarean birth. Mothers and nurses took technical aspects of care for granted, whereas physicians discussed this more explicitly, noting that nurses were their 'eyes and ears' during labour. Participants endorsed caesarean rates and breastfeeding rates as likely to be nurse-sensitive. Stakeholder values support inclusion of maternity nursing care quality measures related to emotional support and providing information in addition to physical support and clinical aspects of care. Care models that ensure labour nurses have sufficient time and resources to engage in the supportive relationships that women value might contribute to better health outcomes and improved patient experience.

The progressivity of health-care financing in Kenya.

PubMed

Munge, Kenneth; Briggs, Andrew Harvey

2014-10-01

Health-care financing should be equitable. In many developing countries such as Kenya, changes to health-care financing systems are being implemented as a means of providing equitable access to health care with the aim of attaining universal coverage. Vertical equity means that people of dissimilar ability to pay make dissimilar levels of contribution to the health-care financing system. Vertical equity can be analysed by measuring progressivity. The aim of this study was to analyse progressivity by measuring deviations from proportionality in the relationship between sources of health-care financing and ability to pay using Kakwani indices applied to data from the Kenya Household Health Utilisation and Expenditure Survey 2007. Concentration indices and Kakwani indices were obtained for the sources of health-care financing: direct and indirect taxes, out of pocket (OOP) payments, private insurance contributions and contributions to the National Hospital Insurance Fund. The bootstrap method was used to analyse the sensitivity of the Kakwani index to changes in the equivalence scale or the use of an alternative measure of ability to pay. The overall health-care financing system was regressive. Out of pocket payments were regressive with all other payments being proportional. Direct taxes, indirect taxes and private insurance premiums were sensitive to the use of income as an alternative measure of ability to pay. However, the overall finding of a regressive health-care system remained. Reforms to the Kenyan health-care financing system are required to reduce dependence on out of pocket payments. The bootstrap method can be used in determining the sensitivity of the Kakwani index to various assumptions made in the analysis. Further analyses are required to determine the equity of health-care utilization and the effect of proposed reforms on overall equity of the Kenyan health-care system.

To examine the influence of depression on health care utilization and costs among women with disabilities and to determine whether the severity of other secondary health conditions affects this association. A time series of 7 interviews over a 1-year period. Large, southern metropolitan area. Community-dwelling women (N=349) with a self-identified diagnosis of a physical disability. Not applicable. Primary disability, secondary health conditions (Health Conditions Checklist), depressive symptoms (Beck Depression Inventory-Second Edition), and health care utilization (based on the Health and Social Service Utilization Questionnaire and the Stanford Health Assessment Questionnaire). We estimated health care costs using standardized criteria and published average costs. Outpatient and emergency department health care utilization and overall costs were higher in women with depressive symptoms and increased with the frequency and severity of the symptoms. Depressive symptoms were highly correlated with the severity of secondary health conditions. Adjusting for demographics and primary disability, both the presence and severity of depressive symptoms were associated with significantly higher health care costs. However, secondary health condition severity explained the association between depressive symptoms and cost; it also substantially increased the variance in cost that was explained by the multivariate models. Secondary health conditions are significantly associated with depressive symptoms and higher health care costs, with secondary health conditions accounting for the association between depressive symptoms and costs. This association suggests that effective management of secondary health conditions may help reduce both depressive symptomatology and health care costs.

Oral care.

Adequate dental and oral hygiene may become a challenge for all users and especially for elderly people and young children because of their limited motor skills. The same holds true for patients undergoing/recovering from chemo-/radiotherapy with accompanying sensitive mucosal conditions. Poor dental hygiene can result in tooth decay, gingivitis, periodontitis, tooth loss, bad breath (halitosis), fungal infection and gum diseases. The use of a toothbrush is the most important measure for oral hygiene. Toothbrushes with soft bristles operated carefully by hand or via an electric device help to remove plaque and to avoid mucosal trauma. A handlebar with a grip cover can be helpful for manually disabled patients or for those with reduced motor skills. In case of oral hygiene at the bedside or of patients during/after chemo-/radiotherapy a gauze pad can be helpful for gently cleaning the teeth, gums and tongue. The use of fluoride toothpaste is imperative for the daily oral hygiene. Detergents such as sodium lauryl sulphate improve the cleaning action but may also dehydrate and irritate the mucous membrane. The use of products containing detergents and flavouring agents (peppermint, menthol, cinnamon) should therefore be avoided by bedridden patients or those with dry mouth and sensitive mucosa. Aids for suitable interdental cleaning, such as dental floss, interdental brushes or dental sticks, are often complicated to operate. Their correct use should be instructed by healthcare professionals. To support dental care, additional fluoridation with a fluoride gel or rinse can be useful. Products further containing antiseptics such as chlorhexidine or triclosan reduce the quantity of bacteria in the mouth. For patients undergoing or having undergone radio-/chemotherapy, a mouthwash that concomitantly moisturizes the oral mucosa is advisable. Copyright © 2011 S. Karger AG, Basel.

This study was designed to develop a novel technique called non-invasive keratograph dry-up time (NIK-DUT), which used an adapted corneal topographer, to analyse in-vitro contact lens surface dewetting and the effects of combinations of lenses and lens care solutions on dewetting. Variables were assessed to optimise sensitivity and reproducibility. To validate the method, in-vitro dewetting of silicone hydrogel contact lenses (balafilcon A, comfilcon A, lotrafilcon A, lotrafilcon B and senofilcon A) was tested. All lens types were soaked in OPTI-FREE ® PureMoist ® Multipurpose Disinfecting Solution (OFPM) and Sensitive Eyes ® Saline Solution. The mean NIK-DUT, defined as drying of 25% of the placido ring measurement segments (NIK-DUT_S25), was calculated for each lens/lens solution combination and a visual map constructed representing the time and location of the dry-up event. Optimal conditions for NIK-DUT measurement included mounting onto a glass stage with a surface geometry of r=8.5mm, e=0, and measuring with high intensity red or white illumination. This method detected significant differences in contact lens dewetting with different lens soaking solutions. NIK-DUT_S25 for all lenses was longer when pre-soaked in OFPM versus saline. Visual analysis showed that dewetting of contact lenses was not uniform across surfaces and differed between test solutions. NIK-DUT is suitable for detecting differences in dewetting among various contact lenses and lens-care combinations. NIK-DUT can quantify the dewetting of large areas of lens surfaces with little subjective influence. Lens care solutions containing surface-active wetting agents were found to delay surface dewetting of silicone hydrogel lenses. Copyright © 2017. Published by Elsevier Ltd.

Stir bar sorptive extraction and liquid desorption followed by high performance liquid chromatography with diode array detection (SBSE-LD-LC-DAD) is proposed for the determination of triclosan in personal care products, biological and environmental matrices, which is included in the priority lists, set by several international regulatory organizations. Instrumental conditions and experimental parameters that affecting SBSE-LD efficiency are fully discussed. Throughout systematic assays on 25 mL water samples spiked at the 10.0 microg L(-1) level, it had been established that stir bars coated with 126 microL of polydimethylsiloxane, an equilibrium time of 1h (1000 rpm) and acetonitrile under sonification (60 min) as back-extraction solvent, allowed the best analytical performance to determine triclosan in water matrices. From the data obtained, good recovery and remarkable repeatability were attained, providing experimental average yields (78.5+/-2.2%), although slightly lower than the theoretical equilibrium (99.7%) described by the octanol-water partition coefficients (K(PDMS/W)0.9992) from 0.4 to 108.0 microg L(-1). The application of the present method to determine triclosan in real matrices such as commercial toothpaste, saliva and urban wastewater samples, allowed appropriate selectivity, high sensitivity and accuracy using the standard addition methodology. The proposed method showed to be feasible and sensitive with a low-sample volume requirement to monitor triclosan in personal care products, biological and environmental matrices at the trace level, in compliance with international regulatory directives.

Despite the high prevalence and major public health ramifications, obstructive sleep apnea syndrome (OSAS) remains underdiagnosed. In many developed countries, because community pharmacists (CP) are easily accessible, they have been developing additional clinical services that integrate the services of and collaborate with other healthcare providers (general practitioners (GPs), nurses, etc.). Alternative strategies for primary care screening programs for OSAS involving the CP are discussed. To estimate the quality of life, costs, and cost-effectiveness of three screening strategies among patients who are at risk of having moderate to severe OSAS in primary care. Markov decision model. Published data. Hypothetical cohort of 50-year-old male patients with symptoms highly evocative of OSAS. The 5 years after initial evaluation for OSAS. Societal. Screening strategy with CP (CP-GP collaboration), screening strategy without CP (GP alone) and no screening. Quality of life, survival and costs for each screening strategy. Under almost all modeled conditions, the involvement of CPs in OSAS screening was cost effective. The maximal incremental cost for "screening strategy with CP" was about 455€ per QALY gained. Our results were robust but primarily sensitive to the treatment costs by continuous positive airway pressure, and the costs of untreated OSAS. The probabilistic sensitivity analysis showed that the "screening strategy with CP" was dominant in 80% of cases. It was more effective and less costly in 47% of cases, and within the cost-effective range (maximum incremental cost effectiveness ratio at €6186.67/QALY) in 33% of cases. CP involvement in OSAS screening is a cost-effective strategy. This proposal is consistent with the trend in Europe and the United States to extend the practices and responsibilities of the pharmacist in primary care.

Neoplastic metastatic epidural spinal cord compression is a common complication of cancer that causes pain and progressive neurologic impairment. The previous standard treatment for this condition involved corticosteroids and radiotherapy (RT). Direct decompressive surgery with postoperative radiotherapy (S + RT) is now increasingly being chosen by clinicians to significantly improve patients’ ability to walk and reduce their need for opioid analgesics and corticosteroids. A cost-utility analysis was conducted to compare S + RT with RT alone based on the landmark randomized clinical trial by Patchell et al. (2005). It was performed from the perspective of the Ontario Ministry of Health and Long-Term Care. Ontario-based costs were adjusted to 2010 US dollars. S + RT is more costly but also more effective than corticosteroids and RT alone, with an incremental cost-effectiveness ratio of US$250 307 per quality-adjusted life year (QALY) gained. First order probabilistic sensitivity analysis revealed that the probability of S + RT being cost-effective is 18.11%. The cost-effectiveness acceptability curve showed that there is a 91.11% probability of S + RT being cost-effective over RT alone at a willingness-to-pay of US$1 683 000 per QALY. In practice, the results of our study indicate that, by adopting the S + RT strategy, there would still be a chance of 18.11% of not paying extra at a willingness-to-pay of US$50 000 per QALY. Those results are sensitive to the costs of hospice palliative care. Our results suggest that adopting a standard S + RT approach for patients with MSCC is likely to increase health care costs but would result in improved outcomes. PMID:22505658

Pharmaceutical and personal care products (PPCPs) are one of the most important classes of emerging contaminants. The potential of ecological and environmental impacts associated with PPCPs are of particular concern because they continually penetrate the aquatic environment. This work describes a novel ultra-preconcentration technique for the rapid and highly sensitive analysis of selected PPCPs in environmental water matrices at ppt levels. Selected PPCPs were rapidly extracted and concentrated from large volumes of aqueous solutions (500 and 250mL) by solid-phase extraction combined with dispersive liquid-liquid microextraction (SPE-DLLME) and then analyzed using UHPLC-MS/MS. Experimental parameters were carefully investigated and optimized to achieve the best SPE-DLLME efficiency and higher enrichment factors. The best results were obtained using the ternary mixture acetonitrile/methanol/dichloromethane 3:3:4, v/v/v, both as SPE eluent and DLLME extractant/dispersive mixture. DLLME aqueous solution (5% NaCl, 10mgL(-1) TBAB) was also modified to improve the extraction efficiency of more hydrophilic PPCPs. Under the optimal conditions, an exhaustive extraction for most of the investigated analytes (recoveries >70%), with a precision (RSD <10%) and very high enrichment factors were attained for different aqueous matrices (drinking, sea, river and wastewater). Method detection and quantification limits were at very low ppt levels and below 1 and 3ngL(-1), respectively, for 15 of selected PPCPs. The proposed analytical procedure offers numerous advantages such as the simplicity of operation, rapidity, a high enrichment factor and sensitivity. So it is suitable for monitoring and studies of occurrence of PPCPs in different environmental compartments. Copyright © 2014 Elsevier B.V. All rights reserved.

Nursing is the largest healthcare profession in the United States (U.S.). As principal frontline caregivers in the U.S. healthcare system, nurses have tremendous influence over a patient's healthcare experience. A growing body of evidence states that the nursing workforce has a direct impact on healthcare quality. A standardized approach to measuring nursing's contribution to patient care and safety using nursing-sensitive quality indicators assists in examining the extent to which nurses and nursing affect the quality and safety of health care. This article focuses on nursing-sensitive quality indicators and discusses healthcare quality indicators and nursing-sensitive indicators used in the U.S. A summary of the work of the American Nephrology Nurses' Association Task Force on Nephrology Nursing-Sensitive Quality Indicators (NNSQI) and an NNSQI exemplar are provided.

Physical comorbidities associated with mental health conditions contribute to high health care costs. This study examined the impact of having a usual source of care (USC) for physical health on health care utilization, spending, and quality for adults with a mental health condition using Medicaid administrative data. Having a USC decreased the probability of inpatient admissions and readmissions. It decreased expenditures on emergency department visits for physical health, 30-day readmissions, and behavioral health inpatient admissions. It also had a positive effect on several quality measures. Results underscore the importance of a USC for physical health and integrated care for adults with mental health conditions.

Expectations outpace reality: physicians' use of care management tools for patients with chronic conditions.

Carrier, Emily; Reschovsky, James

2009-12-01

Use of care management tools--such as group visits or patient registries--varies widely among primary care physicians whose practices care for patients with four common chronic conditions--asthma, diabetes, congestive heart failure and depression--according to a new national study by the Center for Studying Health System Change (HSC). For example, less than a third of these primary care physicians in 2008 reported their practices use nurse managers to coordinate care, and only four in 10 were in practices using registries to keep track of patients with chronic conditions. Physicians also used care management tools for patients with some chronic conditions but not others. Practice size and setting were strongly related to the likelihood that physicians used care management tools, with solo and smaller group practices least likely to use care management tools. The findings suggest that, along with experimenting with financial incentives for primary care physicians to adopt care management tools, policy makers might consider developing community-level care management resources, such as nurse managers, that could be shared among smaller physician practices.

There are inequalities in health among migrants and local populations in Europe. Due to migration, Germany, Norway and Sweden have become ethnic culturally diverse nations. There are barriers to mental health care access for refugees, migrants and minorities, and problems with quality of culturally sensitive care in the three countries. This is despite tax-funded health care systems based on equity in service provision. There is a need to develop culturally sensitive mental health services that respond to the increasing diversity of the populations. In this chapter, we will take a closer look at cultural diversity in the countries in question, discuss challenges and give examples of current work to open up mental health services to cultural diversity. The German example will focus on the movement of Interkulturelle Öffnung (cross-cultural opening of the health care system) and work on creating national guidelines and quality standards. From Norway, the work of the National Centre for Mental Health for the indigenous Sámi population will be presented. The Swedish example will focus on the work carried out by the Transcultural Centre. The latter is a competence centre supporting development of culturally sensitive care as an integrated part of the regional health and mental health care system in Stockholm. Finally, the relevance of mental health care for a culturally diverse population, as a part of the larger social project of building tolerant multicultural societies, will be discussed.

US health care spending has continued to increase, and now accounts for more than 17% of the US economy. Despite the size and growth of this spending, little is known about how spending on each condition varies by age and across time. To systematically and comprehensively estimate US spending on personal health care and public health, according to condition, age and sex group, and type of care. Government budgets, insurance claims, facility surveys, household surveys, and official US records from 1996 through 2013 were collected and combined. In total, 183 sources of data were used to estimate spending for 155 conditions (including cancer, which was disaggregated into 29 conditions). For each record, spending was extracted, along with the age and sex of the patient, and the type of care. Spending was adjusted to reflect the health condition treated, rather than the primary diagnosis. Encounter with US health care system. National spending estimates stratified by condition, age and sex group, and type of care. From 1996 through 2013, $30.1 trillion of personal health care spending was disaggregated by 155 conditions, age and sex group, and type of care. Among these 155 conditions, diabetes had the highest health care spending in 2013, with an estimated $101.4 billion (uncertainty interval [UI], $96.7 billion-$106.5 billion) in spending, including 57.6% (UI, 53.8%-62.1%) spent on pharmaceuticals and 23.5% (UI, 21.7%-25.7%) spent on ambulatory care. Ischemic heart disease accounted for the second-highest amount of health care spending in 2013, with estimated spending of $88.1 billion (UI, $82.7 billion-$92.9 billion), and low back and neck pain accounted for the third-highest amount, with estimated health care spending of $87.6 billion (UI, $67.5 billion-$94.1 billion). The conditions with the highest spending levels varied by age, sex, type of care, and year. Personal health care spending increased for 143 of the 155 conditions from 1996 through 2013. Spending on low back and neck pain and on diabetes increased the most over the 18 years, by an estimated $57.2 billion (UI, $47.4 billion-$64.4 billion) and $64.4 billion (UI, $57.8 billion-$70.7 billion), respectively. From 1996 through 2013, spending on emergency care and retail pharmaceuticals increased at the fastest rates (6.4% [UI, 6.4%-6.4%] and 5.6% [UI, 5.6%-5.6%] annual growth rate, respectively), which were higher than annual rates for spending on inpatient care (2.8% [UI, 2.8%-2.8%] and nursing facility care (2.5% [UI, 2.5%-2.5%]). Modeled estimates of US spending on personal health care and public health showed substantial increases from 1996 through 2013; with spending on diabetes, ischemic heart disease, and low back and neck pain accounting for the highest amounts of spending by disease category. The rate of change in annual spending varied considerably among different conditions and types of care. This information may have implications for efforts to control US health care spending.

Workarounds and obstacles: unexpected source of innovation.

PubMed

Lalley, Cathy

2014-01-01

Nurse leaders are aware that nurses are finding ways to adapt health information technology to patient care activities. Previous literature has presented nurses' response to technology obstacles as a work-around, characterized as a negative behavior. Using narrative inquiry, this article examines 9 direct care nurses' interactions on a medical/surgical/telemetry unit. Specifically, nurses' encounters with technology obstacles will be addressed from a complexity science perspective. Four support staff including the clinical nurse manager, pharmacist, quality nurse, and project manager who is also a nurse were interviewed as part of data collection. Complexity science provides nurse leaders' insight into nurses' behavior where outcomes emerge from tensions in the environment through multidirectional and self-organizing interactions. Innovation was found when nurses responded to health information technology obstacles with self-organizing interactions, sensitivity to initial conditions, and multidirectionality. Their actions were also influenced by many sets of rules. Nurses self-organized with coworkers to find better ways to deliver care to patients when using technology. Opportunities exist for nurse leaders to facilitate interactions among nurses and other members of the organization to realize better use of health information technology that improves the patient experience.

Diabetes and the Motivated Patient: Understanding Perlocutionary Effect in Health Communication.

Health care providers (HCP) understand the importance of keeping patients motivated but may be unaware how their words may have unintended negative effects upon their patient's lives. People with diabetes report being told by their HCP that they are "cured" or that they are praised for strides made in weight loss and/or lowered blood glucose, and interpret these messages in unexpected ways. For this paper, we focus upon one case to illustrate the depth and nuance of the patient-provider communication as it emerged within a larger interview-based ethnographic study. Audio-recorded interviews and transcriptions were analyzed discursively. Discourse analysis reveals the ways ideology affects how the patient responds to HCP's utterances and how this affects diabetes self-care. Findings indicate significant perlocutionary effects upon health outcomes, varying both positively and/or negatively. This study points to the importance of carefully considering the power of words and whenever possible knowing the patient's ideological orientation to their world. HCPs should be explicit and deliberate with their communication. Sensitization to the various ways patients hear and react to messages in a clinical setting may lead to improved health outcomes, especially for those with chronic health conditions such as diabetes mellitus.

Physical tests for shoulder impingements and local lesions of bursa, tendon or labrum that may accompany impingement.

Impingement is a common cause of shoulder pain. Impingement mechanisms may occur subacromially (under the coraco-acromial arch) or internally (within the shoulder joint), and a number of secondary pathologies may be associated. These include subacromial-subdeltoid bursitis (inflammation of the subacromial portion of the bursa, the subdeltoid portion, or both), tendinopathy or tears affecting the rotator cuff or the long head of biceps tendon, and glenoid labral damage. Accurate diagnosis based on physical tests would facilitate early optimisation of the clinical management approach. Most people with shoulder pain are diagnosed and managed in the primary care setting. To evaluate the diagnostic accuracy of physical tests for shoulder impingements (subacromial or internal) or local lesions of bursa, rotator cuff or labrum that may accompany impingement, in people whose symptoms and/or history suggest any of these disorders. We searched electronic databases for primary studies in two stages. In the first stage, we searched MEDLINE, EMBASE, CINAHL, AMED and DARE (all from inception to November 2005). In the second stage, we searched MEDLINE, EMBASE and AMED (2005 to 15 February 2010). Searches were delimited to articles written in English. We considered for inclusion diagnostic test accuracy studies that directly compared the accuracy of one or more physical index tests for shoulder impingement against a reference test in any clinical setting. We considered diagnostic test accuracy studies with cross-sectional or cohort designs (retrospective or prospective), case-control studies and randomised controlled trials. Two pairs of review authors independently performed study selection, assessed the study quality using QUADAS, and extracted data onto a purpose-designed form, noting patient characteristics (including care setting), study design, index tests and reference standard, and the diagnostic 2 x 2 table. We presented information on sensitivities and specificities with 95% confidence intervals (95% CI) for the index tests. Meta-analysis was not performed. We included 33 studies involving 4002 shoulders in 3852 patients. Although 28 studies were prospective, study quality was still generally poor. Mainly reflecting the use of surgery as a reference test in most studies, all but two studies were judged as not meeting the criteria for having a representative spectrum of patients. However, even these two studies only partly recruited from primary care.The target conditions assessed in the 33 studies were grouped under five main categories: subacromial or internal impingement, rotator cuff tendinopathy or tears, long head of biceps tendinopathy or tears, glenoid labral lesions and multiple undifferentiated target conditions. The majority of studies used arthroscopic surgery as the reference standard. Eight studies utilised reference standards which were potentially applicable to primary care (local anaesthesia, one study; ultrasound, three studies) or the hospital outpatient setting (magnetic resonance imaging, four studies). One study used a variety of reference standards, some applicable to primary care or the hospital outpatient setting. In two of these studies the reference standard used was acceptable for identifying the target condition, but in six it was only partially so. The studies evaluated numerous standard, modified, or combination index tests and 14 novel index tests. There were 170 target condition/index test combinations, but only six instances of any index test being performed and interpreted similarly in two studies. Only two studies of a modified empty can test for full thickness tear of the rotator cuff, and two studies of a modified anterior slide test for type II superior labrum anterior to posterior (SLAP) lesions, were clinically homogenous. Due to the limited number of studies, meta-analyses were considered inappropriate. Sensitivity and specificity estimates from each study are presented on forest plots for the 170 target condition/index test combinations grouped according to target condition. There is insufficient evidence upon which to base selection of physical tests for shoulder impingements, and local lesions of bursa, tendon or labrum that may accompany impingement, in primary care. The large body of literature revealed extreme diversity in the performance and interpretation of tests, which hinders synthesis of the evidence and/or clinical applicability.

Latex allergy update.

Floyd, P T

2000-02-01

A recent challenge in the hospital environment is the care of patients with latex sensitivity. Since the introduction of universal precautions in the late 1980s, reports of latex sensitivity have soared. The sensitization process and development of latex allergy and its effect on the hospitalized patient are currently under much discussion. Medical personnel must stay abreast of new data and product information to provide up-to-date care for patients, as well as protection for themselves. Statistics have shown a dramatic increase in the incidence of allergy to latex-containing products. Depending on the source, the incidence is thought to range from 15% to 17% for health care workers, as opposed to 1% to 3% for the general population. Other high-risk groups report as much as a 73% incidence of latex allergies. This article explores the issue of latex allergy and its impact on patient care. Signs and symptoms, as well as the etiology of allergic reactions to latex are examined. The basics of the manufacturing and packaging processes are explored, along with elements of diagnosis and screening, with emphasis on the role of the peri-anesthesia nurse.

This study describes a case formulation approach applying a prospective ICF derived clinical tool to assess rehabilitation needs for a community dwelling stroke survivor with care from an outpatient rehabilitation medicine clinic. Case history data on the person were assessed for rehabilitation management planning using a prospective tool to interlink current with projected future functional status in everyday settings. Implicit assessment with reflective action informed decision points at each stage of the rehabilitation process. As a result of reflective action using the prospective tool, rehabilitation management led to significant changes in client participation after limitations to mobility and self care were mapped to the living conditions of the stroke survivor. The context sensitive rehabilitative plan resulted in higher subjective health-related quality of life in the stroke survivor and significant other and enhanced their capacity for participation. Reflective action informed assessment applying ICF concepts to clinical problem solving resulted in positive gains in health-related quality of life in a stroke survivor.

Food allergies (FAs) are of increasing public health concern and are characterized by a large spectrum of diseases. Their diversity is well known for immunologic pathways (IgE, non-IgE-mediated FAs) and natural history. Many other factors and patient characteristics are involved including type of food, exposure route, allergic comorbidities, gender, racial and ethnic backgrounds, cofactors and health conditions. Food allergen components and sensitization profiles are also involved in FA phenotypes. A new approach to chronic disorders based on the identification of phenotypes through extensive knowledge of all the complex components is also applicable to FAs and could lead towards integrative care management. Diagnostic biomarkers for FAs are emerging which also contribute to better care modalities. The aim of this article was to highlight current knowledge regarding the phenotypic diversity of FA. This review will focus on IgE-mediated FAs and how identifying phenotypes may help to better understand the pathophysiological complexity, improve diagnosis and lead to personalized treatment strategies. © 2017 John Wiley & Sons Ltd.

Congestive Heart Failure (CHF) is an ambulatory care sensitive condition, associated with significant morbidity and mortality, rarely with cure. Outpatient based pharmacological management represents the main and most important aspect of care, and is usually lifelong. This narrative styled opinion review looks at the pharmacological agents recommended in the guidelines in context of the Northern Territory (NT) of Australia. We explore the concept of validity, a term used to describe the basis of standardising a particular trial or study and the population to which it is applicable. We aim to highlight the problems of the current guidelines based approach. We also present alternatives that could utilise the core principles from major trials, while incorporating regional considerations, which could benefit clients living in the NT and remote Australia.

Good-quality artemisinin drugs are essential for malaria treatment, but increasing prevalence of poor-quality artemisinin drugs in many endemic countries hinders effective management of malaria cases. To develop a point-of-care assay for rapid identification of counterfeit and substandard artemisinin drugs for resource-limited areas, we used specific monoclonal antibodies against artesunate and artemether, and developed prototypes of lateral flow dipstick assays. In this pilot test, we evaluated the feasibility of these dipsticks under different endemic settings and their performance in the hands of untrained personnel. The results showed that the dipstick tests can be successfully performed by different investigators with the included instruction sheet. None of the artemether and artesunate drugs collected from public pharmacies in different endemic countries failed the test. It is possible that the simple dipstick assays, with future optimization of test conditions and sensitivity, can be used as a qualitative and semi-quantitative assay for rapid screening of counterfeit artemisinin drugs in endemic settings.

The association between managed care enrollments and potentially preventable hospitalization among adult Medicaid recipients in Florida

PubMed Central

2014-01-01

Background The intent of adopting managed care plans is to improve access to health care services while containing costs. To date, there have been a number of studies that examine the relationship between managed care and access to health care. However, the results from previous studies have been inconsistent. Specifically, previous studies did not demonstrate a clear benefit of Medicaid managed care. In this study we have examine whether Medicaid managed care is associated with the probabilities of preventable hospitalizations. This study also analyzes the spillover effect of Medicaid managed care into Medicaid patients in traditional FFS plans and the interaction effects of other patient- and county-level variables on preventable hospitalizations. Methods The study included 254,321 Medicaid patients who were admitted to short-term general hospital in the 67 counties in Florida. Using 2008 hospital inpatient discharge data for working-age adult Medicaid enrollees (18-64 years) in Florida, we conduct multivariate logistic regression analyses to identify possible factors associated with preventable hospitalizations. The first model includes patient- and county-level variables. Then, we add interaction terms between Medicaid HMO and other variables such as race, rurality, market-level factors, and resource for primary care. Results The results show that Medicaid HMO patients are more likely to be hospitalized for ambulatory care sensitive conditions (ACSCs) (OR = 1.30; CI = 1.21, 1.40). We also find that market structure (i.e., competition) is significantly associated with preventable hospitalizations. However, our study does not support that there are spillover effects of Medicaid managed care on preventable hospitalizations for other Medicaid recipients. We find that interactions between Medicaid managed care and race, rurality and market structure are significant. Conclusions The results of our study show that the Medicaid managed care program in Florida was associated with an increase in potentially preventable hospitalizations for Medicaid enrollees. The results suggest that lower capitation rate has been associated with a greater likelihood of preventable hospitalizations for Medicaid managed care patients. Our findings also indicate that increased competition in the Medicaid managed care market has no clear benefit in Medicaid managed care patients. PMID:24916077
