Abstract Objective To investigate adverse events attributed to traditional medical treatments in the Republic of Korea. Methods Adverse events recorded in the Republic of Korea between 1999 and 2010 – by the Food and Drug Administration, the Consumer Agency or the Association of Traditional Korean Medicine – were reviewed. Records of adverse events attributed to the use of traditional medical practices, including reports of medicinal accidents and consumers’ complaints, were investigated. Findings Overall, 9624 records of adverse events attributed to traditional medical practices – including 522 linked to herbal treatments – were identified. Liver problems were the most frequently reported adverse events. Only eight of the adverse events were recorded by the pharmacovigilance system run by the Food and Drug Administration. Of the 9624 events, 1389 – mostly infections, cases of pneumothorax and burns – were linked to physical therapy (n = 285) or acupuncture/moxibustion (n = 1104). Conclusion In the Republic of Korea, traditional medical practices often appear to have adverse effects, yet almost all of the adverse events attributed to such practices between 1999 and 2010 were missed by the national pharmacovigilance system. The Consumer Agency and the Association of Traditional Korean Medicine should be included in the national pharmacovigilance system. PMID:23940404

Objective To examine the impact of diagnostic coding error on estimates of hospital costs attributable to adverse events. Data Sources Original and reabstracted medical records of 9,670 complex medical and surgical admissions at 11 hospital corporations in Ontario from 2002 to 2004. Patient specific costs, not including physician payments, were retrieved from the Ontario Case Costing Initiative database. Study Design Adverse events were identified among the original and reabstracted records using ICD10-CA (Canadian adaptation of ICD10) codes flagged as postadmission complications. Propensity score matching and multivariate regression analysis were used to estimate the cost of the adverse events and to determine the sensitivity of cost estimates to diagnostic coding error. Principal Findings Estimates of the cost of the adverse events ranged from $16,008 (metabolic derangement) to $30,176 (upper gastrointestinal bleeding). Coding errors caused the total cost attributable to the adverse events to be underestimated by 16 percent. The impact of coding error on adverse event cost estimates was highly variable at the organizational level. Conclusions Estimates of adverse event costs are highly sensitive to coding error. Adverse event costs may be significantly underestimated if the likelihood of error is ignored. PMID:22091908

To design a Web-based system to track adverse and near-miss events, to establish an automated method to identify patterns of events, and to assess the adverse event reporting behavior of physicians. A Web-based system was designed to collect physician-reported adverse events including weekly Morbidity and Mortality (M&M) entries and anonymous adverse/near-miss events. An automated system was set up to help identify event patterns. Adverse event frequency was compared with hospital databases to assess reporting completeness. A metropolitan tertiary care center. Identification of adverse event patterns and completeness of reporting. From September 2005 to August 2007, 15,524 surgical patients were reported including 957 (6.2%) adverse events and 34 (0.2%) anonymous reports. The automated pattern recognition system helped identify 4 event patterns from M&M reports and 3 patterns from anonymous/near-miss reporting. After multidisciplinary meetings and expert reviews, the patterns were addressed with educational initiatives, correction of systems issues, and/or intensive quality monitoring. Only 25% of complications and 42% of inpatient deaths were reported. A total of 75.2% of adverse events resulting in permanent disability or death were attributed to the nature of the disease. Interventions to improve reporting were largely unsuccessful. We have developed a user-friendly Web-based system to track complications and identify patterns of adverse events. Underreporting of adverse events and attributing the complication to the nature of the disease represent a problem in reporting culture among surgeons at our institution. Similar systems should be used by surgery departments, particularly those affiliated with teaching hospitals, to identify quality improvement opportunities.

This study aimed to clarify whether work-related adverse events in cases involving compensation for mental disorders and suicide differ by sex and industry using a database containing all relevant cases reported from 2010 to 2014 in Japan. A total of 1362 eligible cases involving compensation for mental disorders (422 females and 940 males) were analyzed. Among males, 55.7% of cases were attributed to "long working hours." In both sexes, the frequencies of cases attributed to "long working hours" and other events differed significantly by industry. Among cases involving compensation for suicide, 71.4% were attributed to "long working hours." The frequency distribution of work-related adverse events differed significantly by sex and industry. These differences should be taken into consideration in the development of industry-specific preventive measures for occupational mental disorders.

Summary Routine mass immunization programs have contributed greatly to the control of infectious diseases and to the improvement of the health of populations. Over the last decades, the rise of antivaccination movements has threatened the advances made in this field to the point that vaccination coverage rates have decreased and outbreaks of vaccine-preventable diseases have resurfaced. One of the critical points of the immunization debate revolves around the level of risk attributable to vaccination, namely the possibility of experiencing serious and possibly irreversible adverse events. Unfortunately, the knowledge about adverse events, especially rare ones, is usually incomplete at best and the attribution of a causal relationship with vaccinations is subject to significant uncertainties. The aim of this paper is to provide a narrative review of seven rare or very rare adverse events: hypotonic hyporesponsive episode, multiple sclerosis, apnea in preterm newborns, Guillain-Barré syndrome, vasculitides, arthritis/ arthralgia, immune thrombocytopenic purpura. We have selected these adverse events based on our experience of questions asked by health care workers involved in vaccination services. Information on the chosen adverse events was retrieved from Medline using appropriate search terms. The review is in the form of questions and answers for each adverse event, with a view to providing useful and actionable concepts while not ignoring the uncertainties that remain. We also highlight in the conclusion possible future improvements to adverse event detection and assessment that could help identify individuals at higher risk against the probable future backdrop of ever-greater abandonment of compulsory vaccination policies.

To assess the reporting rates of serious adverse events attributable to yellow fever vaccination with 17D and 17DD strains as reported in pharmacovigilance databases, and assess reasons for differences in reporting rates. We searched 9 electronic databases for peer reviewed and grey literature (government reports, conferences), in all languages. Reference lists of key studies were also reviewed to identify additional studies. We identified 2,415 abstracts, of which 472 were selected for full text review. We identified 15 pharmacovigilance databases which reported adverse events attributed to yellow fever vaccination, of which 10 contributed data to this review with about 107,600,000 patients (allowing for overlapping time periods for the studies of the US VAERS database), and the data are very heavily weighted (94%) by the Brazilian database. The estimates of serious adverse events form three groups. The estimates for Australia were low at 0/210,656 for "severe neurological disease" and 1/210,656 for YEL-AVD, and also low for Brazil with 9 hypersensitivity events, 0.23 anaphylactic shock events, 0.84 neurologic syndrome events and 0.19 viscerotropic events cases/million doses. The five analyses of partly overlapping periods for the US VAERS database provide an estimate of 3.6/cases per million YEL-AND in one analysis and 7.8 in another, and 3.1 YEL-AVD in one analysis and 3.9 in another. The estimates for the UK used only the inclusive term of "serious adverse events" not further classified into YEL-And or YEL-AND and reported 34 "serious adverse events." The Swiss database used the term "serious adverse events" and reported 7 such events (including 4 "neurologic reactions") for a reporting rate of 25 "serious adverse events"/million doses. Reporting rates for serious adverse events following yellow fever vaccination are low. Differences in reporting rates may be due to differences in definitions, surveillance system organisation, methods of reporting cases, administration of YFV with other vaccines, incomplete information about denominators, time intervals for reporting events, the degree of passive reporting, access to diagnostic resources, and differences in time periods of reporting.

The aim of the review was to analyze conceptual and operational aspects of systems for surveillance of adverse events following immunization. Articles available in electronic format were included, published between 1985 and 2009, selected from the PubMed/Medline databases using the key words "adverse events following vaccine surveillance", "post-marketing surveillance", "safety vaccine" and "Phase IV clinical trials". Articles focusing on specific adverse events were excluded. The major aspects underlying the Public Health importance of adverse events following vaccination, the instruments aimed at ensuring vaccine safety, and the purpose, attributes, types, data interpretation issues, limitations, and further challenges in adverse events following immunization were describe, as well as strategies to improve sensitivity. The review was concluded by discussing the challenges to be faced in coming years with respect to ensuring the safety and reliability of vaccination programs.

Several medicinal products have been withdrawn from the market because of drug-attributed deaths. However, there has been no investigation of whether such withdrawals were justified, and the extent to which confirmatory studies are used to investigate drug-adverse event relationships when deaths are reported is uncertain. We documented medicinal products withdrawn from the market because of drug-attributed deaths, identified confirmatory studies investigating the drug-adverse event relationships, examined whether withdrawals of medicinal products because of drug-attributed deaths after marketing were justified based on a mechanistic analysis, and examined the trends over time. We searched electronic and non-electronic sources to identify medicinal products that were withdrawn because of drug-attributed deaths. We used a previously published algorithm to examine whether the withdrawals of products were justified. We then searched PubMed and Google Scholar to identify studies investigating the drug-adverse event relationships, used the Oxford Centre for Evidence-Based Medicine criteria to document the levels of evidence, and assessed whether the evidence of an association was confirmed. We included 83 medicinal products. The reasons for withdrawal appeared to have been justified in 80 cases (96%). The median interval between the first reported adverse reaction that was related to the cause of death and the first reported death was 1 year (interquartile range = 1-3); products were withdrawn sooner when the interval between the first reported relevant adverse reaction and the first death was shorter. Confirmatory studies were conducted in 57 instances (69%), and there was evidence of an association in 52 cases (63%). Four products (5%) were re-introduced after initial withdrawal. Regulatory authorities have been justified in making withdrawal decisions when deaths have been attributed to medicinal products, using the precautionary principle when alternative decisions could have been made. Medicinal products are likely to be quickly withdrawn from the market when there is a short interval to the first reported deaths. The use of an algorithm such as we have used in this study could help to expedite the process of decision making.

Uncertainties about the cardiovascular safety of sibutramine led to the SCOUT trial that is investigating sibutramine plus weight management in high-risk, overweight/obese patients. A 6-week lead-in period during which all patients received sibutramine permitted an initial assessment of tolerability. A total of 10,742 patients received sibutramine and 3.1% of these discontinued due to an adverse event; issues affecting more than 10 patients were drug intolerance, headache, insomnia, nausea, dry mouth, and constipation-, tachycardia-, and hypertension-related events. Serious adverse events, most commonly associated with the System Organ Class, Cardiac disorders, were reported by 2.7% of patients; however, the majority was not considered sibutramine-related. Adverse events relating to high blood pressure and/or pulse rate, whether reported as adverse events leading to discontinuation, or serious adverse events were reported by less than 0.2% of patients. No serious or individual events leading to discontinuation occurred in more than 25 patients. There were 15 (0.1%) deaths; 10 were attributed to a cardiovascular cause. Discontinuations for adverse events were lower than anticipated. Serious adverse events generally reflected sibutramine's known pharmacology or were related to cardiac disorders already present in this high-risk population. When compared with epidemiological data, overall mortality rate was low and sibutramine was well tolerated in this mainly off-label population. No new safety issues were detected.

Background and Objectives A photochemical treatment process (PCT) utilizing amotosalen and UVA light (INTERCEPT™ Blood System) has been developed for inactivation of viruses, bacteria, parasites and leucocytes that can contaminate blood components intended for transfusion. The objective of this study was to further characterize the safety profile of INTERCEPT-treated platelet components (PCT-PLT) administered across a broad patient population. Materials and Methods This open-label, observational haemovigilance programme of PCT-PLT transfusions was conducted in 21 centres in 11 countries. All transfusions were monitored for adverse events within 24 h post-transfusion and for serious adverse events (SAEs) up to 7 days post-transfusion. All adverse events were assessed for severity (Grade 0–4), and causal relationship to PCT-PLT transfusion. Results Over the course of 7 years in the study centres, 4067 patients received 19 175 PCT-PLT transfusions. Adverse events were infrequent, and most were of Grade 1 severity. On a per-transfusion basis, 123 (0·6%) were classified an acute transfusion reaction (ATR) defined as an adverse event related to the transfusion. Among these ATRs, the most common were chills (77, 0·4%) and urticaria (41, 0·2%). Fourteen SAEs were reported, of which 2 were attributed to platelet transfusion (<0·1%). No case of transfusion-related acute lung injury, transfusion-associated graft-versus-host disease, transfusion-transmitted infection or death was attributed to the transfusion of PCT-PLT. Conclusion This longitudinal haemovigilance safety programme to monitor PCT-PLT transfusions demonstrated a low rate of ATRs, and a safety profile consistent with that previously reported for conventional platelet components.

Dietary supplements, such as herbal or complementary nutritional products and micronutrients (vitamins and minerals), are commonly used in the United States, yet national data on adverse effects are limited. We used nationally representative surveillance data from 63 emergency departments obtained from 2004 through 2013 to describe visits to U.S. emergency departments because of adverse events related to dietary supplements. On the basis of 3667 cases, we estimated that 23,005 (95% confidence interval [CI], 18,611 to 27,398) emergency department visits per year were attributed to adverse events related to dietary supplements. These visits resulted in an estimated 2154 hospitalizations (95% CI, 1342 to 2967) annually. Such visits frequently involved young adults between the ages of 20 and 34 years (28.0% of visits; 95% CI, 25.1 to 30.8) and unsupervised children (21.2% of visits; 95% CI, 18.4 to 24.0). After the exclusion of unsupervised ingestion of dietary supplements by children, 65.9% (95% CI, 63.2 to 68.5) of emergency department visits for single-supplement-related adverse events involved herbal or complementary nutritional products; 31.8% (95% CI, 29.2 to 34.3) involved micronutrients. Herbal or complementary nutritional products for weight loss (25.5%; 95% CI, 23.1 to 27.9) and increased energy (10.0%; 95% CI, 8.0 to 11.9) were commonly implicated. Weight-loss or energy products caused 71.8% (95% CI, 67.6 to 76.1) of supplement-related adverse events involving palpitations, chest pain, or tachycardia, and 58.0% (95% CI, 52.2 to 63.7) involved persons 20 to 34 years of age. Among adults 65 years of age or older, choking or pill-induced dysphagia or globus caused 37.6% (95% CI, 29.1 to 46.2) of all emergency department visits for supplement-related adverse events; micronutrients were implicated in 83.1% (95% CI, 73.3 to 92.9) of these visits. An estimated 23,000 emergency department visits in the United States every year are attributed to adverse events related to dietary supplements. Such visits commonly involve cardiovascular manifestations from weight-loss or energy products among young adults and swallowing problems, often associated with micronutrients, among older adults.

Meningococcal B (MenB) vaccines have been licensed in many countries with private purchase the only option until recently, when a funded programme was introduced in the UK. The aim of this study was to explore adolescent/parental values for a variety of salient vaccine attributes (cost, effectiveness, side effect profile) to assess preferences and willingness-to-pay (WTP) for a MenB vaccine. A national cross-sectional population study was conducted in Australia using Discrete Choice Experiment methodology to assess adolescent/parent/adult preferences for attributes related to MenB vaccine. 2003 adults and 502 adolescents completed the survey in 2013. The majority of participants were willing to be vaccinated with MenB vaccine with vaccination opt-out chosen by 11.9% of adolescents and parents, and 18.2% of non-parent adults. A mixed logit regression model examining adolescent/adult preferences indicated consistent findings; the higher the effectiveness, the longer the duration of protection, the less chance of adverse events and the lower the cost, the more likely respondents were to agree to vaccination. For an ideal MenB vaccine, including the most favoured level of each attribute summed together (90% effectiveness, 10 year duration, 1 injection, no adverse events) adolescents would pay AU$251.60 and parents AU$295.10. Adolescents and parents would pay AU$90.70 or AU$127.20 for 90% vaccine effectiveness vs AU$18.50 or AU$16.70 for 70% effectiveness and would want to be financially compensated for 50% effectiveness; pay AU$63.30 or AU$76.40 for 10 years protection; and pay AU$48.50 or AU$49.20 for no vaccine related adverse events. A slight fever post vaccination was a preferred choice with parents and adolescents willing to pay AU$9.60 or AU$12.30 for this attribute. Vaccine effectiveness, adverse events and duration of immunity are important drivers for parental and adolescent decisions about WTP for MenB vaccine and should be included in discussions on the benefits, risks and cost.

Over the last two decades, molecular-targeted agents have become mainstream treatment for many types of malignancies and have improved the overall survival of patients. However, most patients eventually develop resistance to these targeted therapies. Recently, immunotherapies such as immune checkpoint inhibitors have revolutionized the treatment paradigm for many types of malignancies. Immune checkpoint inhibitors have been approved for treatment of melanoma, non-small cell lung cancer, renal cell carcinoma, head and neck squamous cell carcinoma, Hodgkin's lymphoma, bladder cancer and gastric cancer. However, oncologists have been faced with immune-related adverse events caused by immune checkpoint inhibitors; these are generally mild but can be fatal in some cases. Because immune checkpoint inhibitors have distinct toxicity profiles from those of chemotherapy or targeted therapy, many oncologists are not familiar with the principles for optimal management of immune-related adverse events, which require early recognition and appropriate treatment without delay. To achieve this, oncologists must educate patients and health-care workers, develop checklists of appropriate tests for immune-related adverse events and collaborate closely with organ specialists. Clinical questions that remain include whether immune checkpoint inhibitors should be administered to patients with autoimmune disease and whether patients for whom immune-related adverse events lead to delays in immunotherapy should be retreated. In addition, the predicted use of combination immunotherapies in the near future means that oncologists will face a higher incidence and severity of immune-related adverse events. This review provides an overview of the optimal management of immune-related adverse events attributed to immune checkpoint inhibitors.

Background Aspirin has been shown to lower the incidence and the mortality of vascular disease and cancer but its wider adoption appears to be seriously impeded by concerns about gastrointestinal (GI) bleeding. Unlike heart attacks, stroke and cancer, GI bleeding is an acute event, usually followed by complete recovery. We propose therefore that a more appropriate evaluation of the risk-benefit balance would be based on fatal adverse events, rather than on the incidence of bleeding. We therefore present a literature search and meta-analysis to ascertain fatal events attributable to low-dose aspirin. Methods In a systematic literature review we identified reports of randomised controlled trials of aspirin in which both total GI bleeding events and bleeds that led to death had been reported. Principal investigators of studies in which fatal events had not been adequately described were contacted via email and asked for further details. A meta-analyses was then performed to estimate the risk of fatal gastrointestinal bleeding attributable to low-dose aspirin. Results Eleven randomised trials were identified in the literature search. In these the relative risk (RR) of ‘major’ incident GI bleeding in subjects who had been randomised to low-dose aspirin was 1.55 (95% CI 1.33, 1.83), and the risk of a bleed attributable to aspirin being fatal was 0.45 (95% CI 0.25, 0.80). In all the subjects randomised to aspirin, compared with those randomised not to receive aspirin, there was no significant increase in the risk of a fatal bleed (RR 0.77; 95% CI 0.41, 1.43). Conclusions The majority of the adverse events caused by aspirin are GI bleeds, and there appears to be no valid evidence that the overall frequency of fatal GI bleeds is increased by aspirin. The substantive risk for prophylactic aspirin is therefore cerebral haemorrhage which can be fatal or severely disabling, with an estimated risk of one death and one disabling stroke for every 1,000 people taking aspirin for ten years. These adverse effects of aspirin should be weighed against the reductions in vascular disease and cancer. PMID:27846246

Purpose The goal of this study is to summarize trends in rates of adverse events attributable to acetaminophen use, including hepatotoxicity and mortality. Methods A comprehensive analysis of data from three national surveillance systems estimated rates of acetaminophen-related events identified in different settings, including calls to poison centers (2008–2012), emergency department visits (2004–2012), and inpatient hospitalizations (1998–2011). Rates of acetaminophen-related events were calculated per setting, census population, and distributed drug units. Results Rates of poison center calls with acetaminophen-related exposures decreased from 49.5/1000 calls in 2009 to 43.5/1000 calls in 2012. Rates of emergency department visits for unintentional acetaminophen-related adverse events decreased from 58.0/1000 emergency department visits for adverse drug events in 2009 to 50.2/1000 emergency department visits in 2012. Rates of hospital inpatient discharges with acetaminophen-related poisoning decreased from 119.8/100 000 hospitalizations in 2009 to 108.6/100 000 hospitalizations in 2011. After 2009, population rates of acetaminophen-related events per 1million census population decreased for poison center calls and hospitalizations, while emergency department visit rates remained stable. However, when accounting for drug sales, the rate of acetaminophen-related events (per 1 million distributed drug units) increased after 2009. Prior to 2009, the rates of acetaminophen-related hospitalizations had been slowly increasing (p-trend = 0.001). Conclusions Acetaminophen-related adverse events continue to be a public health burden. Future studies with additional time points are necessary to confirm trends and determine whether recent risk mitigation efforts had a beneficial impact on acetaminophen-related adverse events.

The US Food and Drug Administration Adverse Event Reporting System (FAERS) is a global passive surveillance database that relies on voluntary reporting by health care professionals and consumers as well as required mandatory reporting by pharmaceutical manufacturers. However, the initial filers and comparative patterns for oral P2Y12 platelet inhibitor reporting are unknown. We assessed who generated original FAERS reports for clopidogrel, prasugrel, and ticagrelor in 2015. From the FAERS database we extracted and examined adverse event cases coreported with oral P2Y12 platelet inhibitors. All adverse event filing originating sources were dichotomized into consumers, lawyers, pharmacists, physicians, other health care professionals, and unknown. Overall, 2015 annual adverse events were more commonly coreported with clopidogrel (n = 13,234) with known source filers (n = 12,818, or 96.9%) than with prasugrel (2,896; 98.9% out of 2,927 cases) or ticagrelor (2,163, or 82.3%, out of 2,627 cases, respectively). Overall, most adverse events were filed by consumers (8,336, or 44.4%), followed by physicians (5,290, or 28.2%), other health care professionals (2,997, or 16.0%), pharmacists (1,125, or 6.0%), and finally by lawyers (129, or 0.7%). The origin of 811 (4.7%) initial reports remains unknown. The adverse event filing sources differ among drugs. While adverse events coreported with clopidogrel and prasugrel were commonly originated by patients (40.4 and 84.3%, respectively), most frequently ticagrelor reports (42.5%) were filed by physicians. The reporting quality and initial sources differ among oral P2Y12 platelet inhibitors in FAERS. The ticagrelor surveillance in 2015 was inadequate when compared to clopidogrel and prasugrel. Patients filed most adverse events for clopidogrel and prasugrel, while physicians originated most ticagrelor complaints. These differences justify stricter compliance control for ticagrelor manufacturers and may be attributed to the confusion of treating physicians with unexpected fatal, cardiac, and thrombotic adverse events linked to ticagrelor. © 2017 S.

Medication errors and adverse drug events are universal problems contributing to patient harm but the magnitude of these problems in Africa remains unclear. The objective of this study was to systematically investigate the literature on the extent of medication errors and adverse drug events, and the factors contributing to medication errors in African hospitals. We searched PubMed, MEDLINE, EMBASE, Web of Science and Global Health databases from inception to 31 August, 2017 and hand searched the reference lists of included studies. Original research studies of any design published in English that investigated adverse drug events and/or medication errors in any patient population in the hospital setting in Africa were included. Descriptive statistics including median and interquartile range were presented. Fifty-one studies were included; of these, 33 focused on medication errors, 15 on adverse drug events, and three studies focused on medication errors and adverse drug events. These studies were conducted in nine (of the 54) African countries. In any patient population, the median (interquartile range) percentage of patients reported to have experienced any suspected adverse drug event at hospital admission was 8.4% (4.5-20.1%), while adverse drug events causing admission were reported in 2.8% (0.7-6.4%) of patients but it was reported that a median of 43.5% (20.0-47.0%) of the adverse drug events were deemed preventable. Similarly, the median mortality rate attributed to adverse drug events was reported to be 0.1% (interquartile range 0.0-0.3%). The most commonly reported types of medication errors were prescribing errors, occurring in a median of 57.4% (interquartile range 22.8-72.8%) of all prescriptions and a median of 15.5% (interquartile range 7.5-50.6%) of the prescriptions evaluated had dosing problems. Major contributing factors for medication errors reported in these studies were individual practitioner factors (e.g. fatigue and inadequate knowledge/training) and environmental factors, such as workplace distraction and high workload. Medication errors in the African healthcare setting are relatively common, and the impact of adverse drug events is substantial but many are preventable. This review supports the design and implementation of preventative strategies targeting the most likely contributing factors.
Avoiding and treating dermal filler complications.

All fillers are associated with the risk of both early and late complications. Early side effects such as swelling, redness, and bruising occur after intradermal or subdermal injections. The patient has to be aware of and accept these risks. Adverse events that last longer than 2 weeks can be attributable to technical shortcomings (e.g., too superficial an implantation of a long-lasting filler substance). Such adverse events can be treated with intradermal 5-fluorouracil, steroid injections, vascular lasers, or intense pulsed light, and later with dermabrasion or shaving. Late adverse events also include immunologic phenomena such as late-onset allergy and nonallergic foreign body granuloma. Both react well to intralesional steroid injections, which often have to be repeated to establish the right dose. Surgical excisions shall remain the last option and are indicated for hard lumps in the lips and visible hard nodules or hard granuloma in the subcutaneous fat.

As healthcare institutions are a focus of smallpox transmission early in an epidemic, several mathematical models support pre-event smallpox vaccination of healthcare workers (HCWs). The deciding factor for HCW voluntary vaccination is the risk of disease exposure versus the risk of vaccine adverse events. In a United States military population, with careful screening to exclude atopic dermatitis/eczema and immunosuppression, over 1 million vaccinia (smallpox) vaccinations were delivered with one fatality attributed to vaccination. Among 37901 United States civilian volunteer HCWs vaccinated, 100 serious adverse events were reported including 10 ischemic cardiac episodes and six myocardial infarctions - two were fatal. This older population had a higher rate of adverse events due to age-related coronary artery disease. T-cell mediated inflammatory processes induced by live vaccinia vaccination may have a role in the observed acute coronary artery events. With exclusion of individuals at risk for coronary artery disease, atopic dermatitis/eczema, and immunosuppression, HCWs can be smallpox vaccinated with minimal risk. A carefully screened multidisciplinary cadre (physician, nurse, infection control practitioner, technician), pre-event vaccinated for smallpox, will supply the necessary leadership to alleviate fear and uncertainty while limiting spread and initial mortality of smallpox.

In September 2005, nearly 3.7 million people evacuated the Texas coastline in advance of Hurricane Rita's landfall, making the event the largest emergency evacuation in US history. The Rita evacuation underscored the importance of planning for domestic mass-evacuation events, as the evacuation itself led to over 100 of the at least 119 deaths attributed to the storm. In the days preceding Rita's landfall, several cascading, interrelated circumstances precipitated such adverse outcomes. This article explores the series of events leading up to the evacuation's poor outcomes, the response following Rita to amend evacuation plans, and how Texas successfully implemented these changes during later storms to achieve better outcomes.

Childhood adversities are strong predictors of psychopathology and suicidality. However, specific adversities are associated with different outcomes, with cross-national variations reported. The current study examined rates of adversities reported in Northern Ireland (NI), and associations between adverse childhood experiences and psychopathology and suicidal behaviour were explored. Data was obtained from the Northern Ireland Study of Health and Stress (NISHS), conducted as part of the World Mental Health (WMH) survey initiative (2004-2008); response rate 68.4% (n = 1,986). The on-line survey used, the WHO Composite International Diagnostic Interview (CIDI) to examine psychopathology and associated risk factors in the NI population. Prevalence rates of retrospectively reported childhood adversities were calculated, with gender and age variations explored. Females were more likely to experience sexual abuse. Individuals who grew up during the worst years of the civil conflict in NI experienced elevated levels of childhood adversities. Participants who endured childhood adversities were more likely to have mental health problems but variations in risk factors were found for different disorders. Parental mental illness was associated with all disorders however, with ORs ranging from 2.20 for mood disorders to 4.07 for anxiety disorders. Population attributable fractions (PAF) estimated the reduction in psychopathology and suicidal behaviour in the population if exposure to adverse childhood events had not occurred. The highest PAF values were revealed for parental mental illness and sexual abuse. The findings indicate that a substantial proportion of psychopathology and suicide risk in NI are attributable to childhood adversities, providing support for early intervention and prevention initiatives.

Background In Fontan and atrial switch patients, transcatheter ablation is limited by difficult access to the pulmonary venous atrium. In recent years, transbaffle access (TBA) has been described, but limited data document its safety and utility. Methods and Results All ablative electrophysiological study cases of this population performed between January 2006 and December 2010 at Boston Children's Hospital were reviewed. Pre‐case and follow‐up clinical characteristics were documented. Adverse events were classified by severity and attributability to the intervention. We included 118 cases performed in 90 patients. TBA was attempted in 74 cases and was successful in 96%: in 20 via baffle leak or fenestration and in 51 (94%) of 54 using standard or radiofrequency transseptal techniques. There were 10 procedures with adverse events ranked as moderate or more severe. The event rate was similar in both groups (TBA 8% versus non‐TBA 9%, P=1), and no events were directly attributable to TBA. There was a trend to higher proportion of cases having a >5‐point drop in saturations from baseline in the TBA group versus the non‐TBA group in Fontan cases (15% vs 0%, P=0.14). When cases with follow‐up >90 and >365 days were analyzed, the median initial arrhythmia score of 5 significantly changed −3 points in both time periods (P≤0.001). Conclusions TBA is feasible in this population; its use was not associated with a higher incidence of adverse events; and changes in clinical scores support its efficacy. Desaturation observed in some patients is of uncertain significance but warrants postablation monitoring and prospective study. PMID:24052498

Oritavancin is a lipoglycopeptide with bactericidal activity against Gram-positive organisms. Its rapid concentration-dependent bactericidal activity and long elimination half-life allow single-dose treatment of acute bacterial skin and skin structure infections (ABSSSI). SOLO I and SOLO II were randomized, double-blind studies evaluating the efficacy and safety of a single 1,200-mg intravenous (i.v.) dose of oritavancin versus twice-daily i.v. vancomycin for 7 to 10 days in ABSSSI patients. Safety data from both studies were pooled for safety analysis. The database comprised pooled safety data for 976 oritavancin-treated patients and 983 vancomycin-treated patients. The incidences of adverse events, serious adverse events, and discontinuations due to adverse events were similar for oritavancin (55.3, 5.8, and 3.7%, respectively) and vancomycin (56.9, 5.9, and 4.2%, respectively). The median time to onset (3.8 days versus 3.1 days, respectively) and the duration (3.0 days for both groups) of adverse events were also similar between the two groups. The most frequently reported events were nausea, headache, and vomiting. Greater than 90% of all events were mild or moderate in severity. There were slightly more infections and infestations, abscesses or cellulitis, and hepatic and cardiac adverse events in the oritavancin group; however, more than 80% of these events were mild or moderate. Subgroup analyses did not identify clinically meaningful differences in the incidence of adverse events attributed to oritavancin. A single 1,200-mg dose of oritavancin was well tolerated and had a safety profile similar to that of twice-daily vancomycin. The long elimination half-life of oritavancin compared to that of vancomycin did not result in a clinically meaningful delay to the onset or prolongation of adverse events.

Adverse events of herbal food supplements for body weight reduction: systematic review.
Pittler, M H; Schmidt, K; Ernst, E
2005-05-01
Herbal weight-loss supplements are marketed with claims of effectiveness. Our earlier systematic review identified data from double-blind, randomized controlled trials for a number of herbal supplements. The aim of this systematic review was to assess all clinical evidence of adverse events of herbal food supplements for body weight reduction for which effectiveness data from rigorous clinical trials exist. We assessed Ephedra sinica, Garcinia cambogia, Paullinia cupana, guar gum, Plantago psyllium, Ilex paraguariensis and Pausinystalia yohimbe. Literature searches were conducted on Medline, Embase, Amed and The Cochrane Library. Data were also requested from the spontaneous reporting scheme of the World Health Organization. We hand-searched relevant medical journals and our own files. There were no restrictions regarding the language of publication. The results show that adverse events including hepatic injury and death have been reported with the use of some herbal food supplements. For herbal ephedra and ephedrine-containing food supplements an increased risk of psychiatric, autonomic or gastrointestinal adverse events and heart palpitations has been reported. In conclusion, adverse events are reported for a number of herbal food supplements, which are used for reducing body weight. Although the quality of the data does not justify definitive attribution of causality in most cases, the reported risks are sufficient to shift the risk-benefit balance against the use of most of the reviewed herbal weight-loss supplements. Exceptions are Garcinia cambogia and yerba mate, which merit further investigation.
Adherence to malaria prophylaxis among Peace Corps Volunteers in the Africa region, 2013.
Landman, Keren Z; Tan, Kathrine R; Arguin, Paul M

Although malaria can be prevented with prophylaxis, it is diagnosed in over 100 Africa-region Peace Corps Volunteers annually. This suggests that prophylaxis non-adherence is a problem in these non-immune travelers. We investigated Volunteers' knowledge, attitudes, and practices regarding prophylaxis using an internet-based survey during August 19-September 30, 2013. Adherence was defined as taking doxycycline or atovaquone-proguanil daily, or taking mefloquine doses no more than 8 days apart. The survey was sent to 3248 Volunteers. Of 781 whose responses were analyzed, 514 (73%) reported adherence to prophylaxis. The most common reasons for non-adherence were forgetting (n = 530, 90%); fear of long-term adverse effects (LTAEs; n = 316, 54%); and experiencing adverse events that Volunteers attributed to prophylaxis (n = 297, 51%). Two hundred fourteen (27%) Volunteers reported not worrying about malaria. On multivariate analysis controlling for sex and experiencing adverse events Volunteers attributed to prophylaxis, the factor most strongly associated with non-adherence was being prescribed mefloquine (OR 5.4, 95% confidence interval 3.2-9.0). We found moderate adherence and a prevailing fear of LTAEs among Volunteers. Strategies to improve prophylaxis adherence may include medication reminders, increasing education about prophylaxis safety and malaria risk, and promoting prompt management of prophylaxis side effects.

The treatment of newborns and infants with congenital toxoplasmosis is standard practice. Some observational studies have examined safety in newborns, but most of these failed to provide sufficient details for a provisional assessment of causality. The aim of this study was to evaluate the clinical and biological adverse effects of the combination of sulfadoxine-pyrimethamine. Sixty-five children treated for 1 year with a combination of sulfadoxine-pyrimethamine (1 dose every 10 days) for congenital toxoplasmosis were followed up to evaluate abnormal hematological values and potential adverse events using a standardized method of causality assessment. Nine patients (13.8%) presented at least 1 adverse clinical event that was nonspecific, such as diarrhea on the day of drug administration, vomiting and agitation. In 1 patient, erythema appeared at the end of the treatment and resolved within 10 days. None of these events was attributed to the treatment. Six patients (9.2%) developed an adverse hematological event (neutropenia, n = 3; eosinophilia, n = 2 and both anemia and eosinophilia, n = 1) that was considered to be possibly related to the sulfadoxine-pyrimethamine combination. Four treatments were temporarily interrupted, and toxicity was observed after readministration of treatment in 1 case only. However, none of these adverse events was life threatening. According to our results and previously published data, the combination of sulfadoxine-pyrimethamine seems to be well tolerated. However, the sample size of our study was too small to rule out the risk of less frequent, but nevertheless severe, reactions and, in particular, of hypersensitivity reactions.

Because most medications for pediatric pulmonary hypertension (PH) are used off label and based on adult trials, little information is available on pediatric-specific adverse events (AEs). Although drug manufacturers are required to submit postmarket AE reports to the Food and Drug Administration (FDA), this information is rarely transmitted to practitioners. In the setting of a recent FDA warning for sildenafil, the authors sought to give a better description of the AEs associated with current therapies in pediatric PH. In January 2010, a written request was made to the Food and Drug Administration for AE records of commonly used PH medications. Reports were screened for pediatric patients, analyzed in terms of AEs, and compared with the medical literature. Arbitrarily, AEs that could be attributed to concomitant medications were not attributed to the PH medication in question. Adverse events occurring in more than 5 % of events for each drug were assumed to be associated with the targeted PH medication. Between November 1997 and December 2009, 588 pediatric AE reports (death in 257 cases) were reported for the three most commonly used therapies: bosentan, epoprostenol, and sildenafil. Many of the AEs were similar to those reported previously. However, 27 AEs not previously reported in the literature (e.g., pulmonary hemorrhage, hemoptysis, and pneumonia) were found. The FDA postmarket records for PH medications in pediatric patients show a significant number of AEs. The discovery of AEs not previously reported will better inform those caring for these complex and critically ill children, and the large number of deaths suggest they may be underreported in current literature.

OBJECTIVE To determine how often serious or life-threatening medication administration errors with the potential to cause patient harm (or potential adverse drug events) result in actual patient harm (or adverse drug events (ADEs)) in the hospital setting. DESIGN Retrospective chart review of clinical events that transpired following observed medication administration errors. BACKGROUND Medication errors are common at the medication administration stage for hospitalized patients. While many of these errors are considered capable of causing patient harm, it is not clear how often patients are actually harmed by these errors. METHODS In a previous study where 14,041 medication administrations in an acute-care hospital were directly observed, investigators discovered 1271 medication administration errors, of which 133 had the potential to cause serious or life-threatening harm to patients and were considered serious or life-threatening potential ADEs. In the current study, clinical reviewers conducted detailed chart reviews of cases where a serious or life-threatening potential ADE occurred to determine if an actual ADE developed following the potential ADE. Reviewers further assessed the severity of the ADE and attribution to the administration error. RESULTS Ten (7.5% [95% C.I. 6.98, 8.01]) actual adverse drug events or ADEs resulted from the 133 serious and life-threatening potential ADEs, of which 6 resulted in significant, three in serious, and one life threatening injury. Therefore 4 (3% [95% C.I. 2.12, 3.6]) serious and life threatening potential ADEs led to serious or life threatening ADEs. Half of the ten actual ADEs were caused by dosage or monitoring errors for anti-hypertensives. The life threatening ADE was caused by an error that was both a transcription and a timing error. CONCLUSION Potential ADEs at the medication administration stage can cause serious patient harm. Given previous estimates of serious or life-threatening potential ADE of 1.33 per 100 medication doses administered, in a hospital where 6 million doses are administered per year, about 4000 preventable ADEs would be attributable to medication administration errors annually.

Adverse Events Following Immunization in Viet Nam in 2013 led to substantial reductions in hepatitis B vaccination coverage (both the birth dose and the three-dose series). In order to estimate the impact of the reduction in vaccination coverage on hepatitis B transmission and future mortality, a widely-used mathematical model was applied to the data from Viet Nam. Using the model, we estimated the number of chronic infections and deaths that are expected to occur in the birth cohort in 2013 and the number of excessive infections and deaths attributable to the drop in immunization coverage in 2013. An excess of 90,137 chronic infections and 17,456 future deaths were estimated to occur in the 2013 birth cohort due to the drop in vaccination coverage. This analysis highlights the importance of maintaining high vaccination coverage and swiftly responding to reported Adverse Events Following Immunization in order to regain consumer confidence in the hepatitis B vaccine.

We investigated the hypothesis that the reporting of a history of traumatic life events may serve as a strategy to control attributions about performance in an evaluative setting (i.e., self-handicapping). Following from Alfred Adler's early theorization in the psychology of use, as well as more recent theory and research on self-handicapping, we predicted that individuals would emphasize the adversity of events and experiences in their background when an uncertain evaluation was expected and when a traumatic background would serve as a suitable excuse for potential failure. Results generally supported the hypothesized self-protective reporting of traumatic life events.

In early phase oncology trials, novel targeted therapies are increasingly being tested in combination with traditional agents creating greater potential for enhanced and new toxicities. When a patient experiences a serious adverse event (SAE), investigators must determine whether the event is attributable to the investigational drug or not. This study seeks to understand the clinical reasoning, tools used and challenges faced by the researchers who assign causality to SAE's. Thirty-two semi-structured interviews were conducted with medical oncologists and trial coordinators at six Canadian academic cancer centres. Interviews were recorded and transcribed verbatim. Individual interview content analysis was followed by thematic analysis across the interview set. Our study found that causality assessment tends to be a rather complex process, often without complete clinical and investigational data at hand. Researchers described using a common processing strategy whereby they gather pertinent information, eliminate alternative explanations, and consider whether or not the study drug resulted in the SAE. Many of the interviewed participants voiced concern that causality assessments are often conducted quickly and tend to be highly subjective. Many participants were unable to identify any useful tools to help in assigning causality and welcomed more objectivity in the overall process. Attributing causality to SAE's is a complex process. Clinical trial researchers apply a logical system of reasoning, but feel that the current method of assigning causality could be improved. Based on these findings, future research involving the development of a new causality assessment tool specifically for use in early phase oncology clinical trials may be useful.

BACKGROUND Repetitive transcranial magnetic stimulation (rTMS) is emerging as a valuable therapeutic and diagnostic tool. rTMS appears particularly promising for disorders characterized by positive sensory phenomena attributable to alterations in sensory cortex excitability. Among these are tinnitus, auditory and visual hallucinations, and pain syndromes. OBJECTIVE Despite studies addressing rTMS efficacy in suppression of positive sensory symptoms, the safety of stimulation of potentially hyperexcitable cortex has not been fully addressed. We performed a systematic literature review and metanalysis to describe the rTMS safety profile in these disorders. METHODS Using the PubMed database, we performed an English-language literature search from January 1985 to April 2011 to review all pertinent publications. Per study, we noted and listed pertinent details. From these data we also calculated a crude per-subject risk for each adverse event. RESULTS 106 publications (n = 1815 subjects) were identified with patients undergoing rTMS for pathologic positive sensory phenomena. Adverse events associated with rTMS were generally mild and occurred in 16.7% of subjects. Seizure was the most serious adverse event, and occurred in three patients with a 0.16% crude per-subject risk. The second most severe adverse event involved aggravation of sensory phenomena, occurring in 1.54%. CONCLUSIONS The published data suggest rTMS for the treatment or diagnosis of pathologic positive sensory phenomena appears to be a relatively safe and well-tolerated procedure. However, published data are lacking in systematic reporting of adverse events, and safety risks of rTMS in these patient populations will have to be addressed in future prospective trials.

There have been epidemiological studies of adverse events (AEs) among general patients but those of patients cared by cardiologist are not well scrutinized. We investigated the occurrence of AEs and medical errors (MEs) among adult patients with cardiology in Japan. We conducted a cross-sectional study of adult outpatients at a Japanese teaching hospital from February through November 2006. We measured AE and ME incidents from patient report, which were verified by medical records, laboratory data, incident reports, and prescription queries. Two independent physicians reviewed the incidents to determine whether they were AEs or MEs and to assess severity and symptoms. We identified 144 AEs and 30 MEs (16.3 and 3.9 per 100 patients, respectively). Of the 144 AEs, 99 were solely adverse drug events (ADEs), 20 were solely non-ADEs, and the remaining 25 were both causes. The most frequent symptoms of ADEs were skin and allergic reactions due to medication. The most frequent symptoms of non-ADEs were bleeding due to therapeutic interventions. Among AEs, 12% was life threatening. Life-threatening AEs were 25% of non-ADEs and 5% of ADEs (P = 0.0003). Among the 30 MEs, 21MEs (70%) were associated with drugs. Adverse events were common among cardiology patients. Adverse drug events were the most frequent AEs, and non-ADEs were more critical than ADEs. Such data should be recognized among practicing physicians to improve the patients' outcomes.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

[Risk Management: concepts and chances for public health].

Errors are a common problem in medicine and occur as a result of a complex process involving many contributing factors. Medical errors significantly reduce the safety margin for the patient and contribute additional costs in health care delivery. In most cases adverse events cannot be attributed to a single underlying cause. Therefore an effective risk management strategy must follow a system approach, which is based on counting and analysis of near misses. The development of defenses against the undesired effects of errors should be the main focus rather than asking the question "Who blundered?". Analysis of near misses (which in this context can be compared to indicators) offers several methodological advantages as compared to the analysis of errors and adverse events. Risk management is an integral element of quality management.
The use of the term 'radiosensitivity' through history of radiation: from clarity to confusion.
Britel, Manon; Bourguignon, Michel; Foray, Nicolas
2018-05-01
The term 'radiosensitivity' appeared for the first time at the beginning of the 20th century, few years after the discovery of X-rays. Initially used by French and German radiologists, it illustrated the risk of radiation-induced (RI) skin reactions. From the 1950s, 'radiosensitivity' was progressively found to describe other features of RI response such as RI cancers or cataracts. To date, such confusion may raise legal issues and complexify the message addressed to general public. Here, through an historical review, we aimed to better understand how this confusion appeared. To support our historical review, a quantitative and qualitative wording analysis of the 'radiosensitivity' occurrences and its derived terms was performed with Google books, Pubmed, Web of Science™ databases, and in all the ICRP publications. While 'radiosensitivity' was historically related to RI adverse tissue events attributable to cell death, the first efforts to quantify the RI risk specific to each organ/tissue revealed some different semantic fields that are not necessarily compatible together (e.g. adverse tissue events for skin, cataracts for eyes, RI cancer for breast or thyroid). To avoid such confusion, we propose to keep the historical definition of 'radiosensitivity' to any clinical and cellular consequences of radiation attributable to cell death and to introduce the term 'radiosusceptibility' to describe the RI cancers or any feature that is attributable to cell transformation.

This study evaluated the 2-year overall survival rate, adverse event rate, local control rate, and impact on pulmonary function tests for medically inoperable patients with stage IA non-small cell lung cancer (NSCLC) undergoing computed tomography (CT)-guided radiofrequency ablation (RFA) in a prospective, multicenter trial. Fifty-four patients (25 men and 29 women) with a median age of 76 years (range, 60-89 years) were enrolled from 16 US centers; 51 patients were eligible for evaluation (they had biopsy-proven stage IA NSCLC and were deemed medically inoperable by a board-certified thoracic surgeon). Pulmonary function tests were performed within the 60 days before RFA and 3 and 24 months after RFA. Adverse events were recorded and categorized. Patients were followed with CT and fludeoxyglucose positron emission tomography. Local control rate and recurrence patterns were analyzed. The overall survival rate was 86.3% at 1 year and 69.8% at 2 years. The local tumor recurrence-free rate was 68.9% at 1 year and 59.8% at 2 years and was worse for tumors > 2 cm. In the 19 patients with local recurrence, 11 were re-treated with RFA, 9 underwent radiation, and 3 underwent chemotherapy. There were 21 grade 3 adverse events, 2 grade 4 adverse events, and 1 grade 5 adverse event in 12 patients within the first 90 days after RFA. None of the grade 4 or 5 adverse events were attributable to RFA. There was no significant change in the forced expiratory volume in the first second of expiration or the diffusing capacity of lung for carbon monoxide after RFA. A tumor size less than 2.0 cm and a performance status of 0 or 1 were associated with statistically significant improved survival of 83% and 78%, respectively, at 2 years. RFA is a single, minimally invasive procedure that is well tolerated in medically inoperable patients, does not adversely affect pulmonary function tests, and provides a 2-year overall survival rate that is comparable to the rate reported after stereotactic body radiotherapy in similar patients. © 2015 American Cancer Society.

HMG-CoA reductase inhibitors [statins], a widely prescribed cholesterol-lowering therapy, are associated with muscle-related adverse events. While characteristics of such events are well documented in Western countries, little data exists for the Thai population. The aim of this study was to determine the characteristics of patients, type and dosing of statin, and to identify patterns of drug use that may be associated with such adverse events using the national pharmacovigilance database known as Thai Vigibase. Muscle-related adverse events involving statins in the Thai Vigibase from 1996 to December 2009 were identified. For each report, the following information was extracted: patient demographics, co-morbidities, detailed information of adverse event, detailed information of suspected drug, treatment and outcome, as well as causality assessment and quality of reports. Descriptive statistics were performed for all study variables. A total of 198 cases of statin-associated muscle-related adverse events were identified. Mean age was 61.4 ± 12.4 years of age and 59.6% were female. Simvastatin, atorvastatin, rosuvastatin and cerivastatin were implicated as the suspected drug in 163 (82.3%), 24 (12.1%), 10 (5.1%) and 1 (0.5%) cases, respectively. Rhabdomyolysis accounted for 55.6% of all muscle-related adverse events. Drug interactions known to enhance such toxicity of statins were identified in 40.9% of the total set of reports. Similar to studies from Western countries, fibrates, HIV protease inhibitors, non-dihydropyridine calcium channel blockers, azole antifungals and macrolides were commonly found in such cases. Interestingly, colchicine has been identified as the second most common drug interaction in our database. Case fatality rates were 0.9, 1.6 and 16.7%, when there were 0, 1 and ≥2 interacting drugs, respectively. Characteristics of muscle-related adverse events with statins in the Thai population showed some similarities and differences compared with Western countries. Such similarities included advanced age, female sex, certain co-morbidities and drug interactions. While the majority of interacting drugs are well known, a big proportion of cases of statin-colchicine interaction attributed to long-term use of colchicine in Thailand was noted and should be further investigated. Based on these results, an attempt to avoid dangerous and well-known drug interactions among statin users should be implemented nationwide.
Judgments of cause and blame: the effects of intentionality and foreseeability.
Lagnado, David A; Channon, Shelley

What are the factors that influence everyday attributions of cause and blame? The current studies focus on sequences of events that lead to adverse outcomes, and examine people's cause and blame ratings for key events in these sequences. Experiment 1 manipulated the intentional status of candidate causes and their location in a causal chain. Participants rated intentional actions as more causal, and more blameworthy, than unintentional actions or physical events. There was also an overall effect of location, with later events assigned higher ratings than earlier events. Experiment 2 manipulated both intentionality and foreseeability. The preference for intentional actions was replicated, and there was a strong influence of foreseeability: actions were rated as more causal and more blameworthy when they were highly foreseeable. These findings are interpreted within two prominent theories of blame, [Shaver, K. G. (1985). The attribution of blame: Causality, responsibility, and blameworthiness. New York: Springer-Verlag] and [Alicke, M. D. (2000). Culpable control and the psychology of blame. Psychological Bulletin, 126, 556-574]. Overall, it is argued that the data are more consistent with Alicke's model of culpable control.

Chronic kidney disease (CKD) is associated with increased rates of adverse events after percutaneous coronary intervention. We sought to determine the impact of CKD on platelet reactivity in clopidogrel-treated patients and whether high platelet reactivity (HPR) confers a similar or differential risk for adverse events among patients with CKD and non-CKD. We performed a post hoc analysis of the Assessment of Dual Antiplatelet Therapy With Drug-Eluting Stents (ADAPT-DES) registry, which included 8582 patients undergoing percutaneous coronary intervention with drug-eluting stents and platelet function testing using the VerifyNow assay. We compared HPR and its impact on ischemic and bleeding events >2 years among patients with CKD and non-CKD. Patients with CKD (n=1367) were older, more often female, diabetic, and had lower ejection fraction compared with their non-CKD counterparts (n=7043). Although HPR prevalence increased with worsening renal function in unadjusted analyses, these associations were no longer present after adjustment. Major adverse cardiac event rates at 2 years among those without CKD or HPR, HPR alone, CKD alone, and both CKD and HPR were 9.0%, 11.2%, 13.3%, and 17.5%, respectively (P<0.001). Associations between HPR and adverse events were uniform across CKD strata without evidence of interaction. HPR is more common among those with versus without CKD, an association that is attributable to confounding risk factors that are more prevalent in CKD. The impact of HPR on ischemic and bleeding events is similar irrespective of CKD status. URL: http://www.clinicaltrials.gov. Unique identifier: NCT00638794. © 2015 American Heart Association, Inc.

The aim of this study was to report an analysis of the concept of patient safety. Despite recent increase in the number of work being done to clarify the concept and standardize measurement of patient safety, there are still huge variations in how the term is conceptualized and how to measure patient safety data across various healthcare settings and in research. Concept analysis. A literature search was conducted through PubMed and Cumulative Index to Nursing and Allied Health Literature, Plus using the terms 'patient safety' in the title and 'concept analysis,' 'attributes' or 'definition' in the title and or abstract. All English language literature published between 2002-2014 were considered for the review. Walker and Avant's method guided this analysis. The defining attributes of patient safety include prevention of medical errors and avoidable adverse events, protection of patients from harm or injury and collaborative efforts by individual healthcare providers and a strong, well-integrated healthcare system. The application of Collaborative Alliance of Nursing Outcomes indicators as empirical referents would facilitate the measurement of patient safety. With the knowledge gained from this analysis, nurses may improve patient surveillance efforts that identify potential hazards before they become adverse events and have a stronger voice in health policy decision-making that influence implementation efforts aimed at promoting patient safety, worldwide. Further studies are needed on development of a conceptual model and framework that can aid with collection and measurement of standardized patient safety data. © 2015 John Wiley & Sons Ltd.

Adherence problems with coitally dependent, female-initiated HIV prevention methods have contributed to several trials' failure to establish efficacy. Continuous use of a cervical barrier with once-daily cleaning and immediate reinsertion may simplify use for women and improve adherence. We assessed the acceptability and safety of precoital and continuous use of the Duet, a cervical barrier and gel delivery system, in Zimbabwean women. Using a two-arm crossover design with a parallel observation group, we randomized 103 women in a 2:2:1 ratio: (1) to use the Duet continuously for 14 days, followed by a minimum of seven days of washout and then 14 days of precoital use; (2) to use the same Duet regimens in reverse order; or (3) for observation only. Women were aged 18 to 40 years; half were recruited from a pool of previous diaphragm study participants and the other half from the general community. Acceptability and adherence were assessed through an interviewer-administered questionnaire at each of two follow-up visits. Safety was monitored through pelvic speculum exams and report of adverse events. The proportion of women who reported consistent Duet use during sex was virtually identical during continuous and precoital regimens (88.6% vs. 88.9%). Partner refusal was the most common reason cited for non-use during sex in both use regimens. Not having the device handy was the most common reason cited for non-daily use (in the continuous regimen). Most women were "very comfortable" using it continuously (86.3%) and inserting it precoitally (92.8%). The most favoured Duet attribute was that it did not interfere with "natural" sex (55%). The least favoured Duet attribute was the concern that it might come out during sex (71.3%). No serious adverse events were reported during the study; 57 participants reported 90 adverse events classified as mild or moderate. There were no statistically significant differences in: (1) the proportion of women reporting adverse events; (2) the severity of events among those using the Duet and observational controls; or (3) event severity reported during each regimen use period. In this study, the Duet was found to be acceptable and safe when inserted precoitally or used continuously for 14 days. Assignment to use of the Duet continuously did not increase adherence to the Duet during sex. Future HIV prevention trials should evaluate use of the Duet (precoitally and continuously) with promising microbicide candidates.

For the purpose of post-marketing drug safety surveillance, which has traditionally relied on the voluntary reporting of individual cases of adverse drug events (ADEs), other sources of information are now being explored, including electronic health records (EHRs), which give us access to enormous amounts of longitudinal observations of the treatment of patients and their drug use. Adverse drug events, which can be encoded in EHRs with certain diagnosis codes, are, however, heavily underreported. It is therefore important to develop capabilities to process, by means of computational methods, the more unstructured EHR data in the form of clinical notes, where clinicians may describe and reason around suspected ADEs. In this study, we report on the creation of an annotated corpus of Swedish health records for the purpose of learning to identify information pertaining to ADEs present in clinical notes. To this end, three key tasks are tackled: recognizing relevant named entities (disorders, symptoms, drugs), labeling attributes of the recognized entities (negation, speculation, temporality), and relationships between them (indication, adverse drug event). For each of the three tasks, leveraging models of distributional semantics - i.e., unsupervised methods that exploit co-occurrence information to model, typically in vector space, the meaning of words - and, in particular, combinations of such models, is shown to improve the predictive performance. The ability to make use of such unsupervised methods is critical when faced with large amounts of sparse and high-dimensional data, especially in domains where annotated resources are scarce.

Mothers' preferences regarding new combination vaccines for their children in Japan, 2014.
Shono, Aiko; Kondo, Masahide
2017-04-03
A number of new vaccines to prevent childhood diseases have been introduced globally over the last few decades. Only four combination vaccines are currently available in Japan, DTaP/sIPV, DTaP, DT, and MR, leading to complex infant vaccine scheduling. This study aims to investigate mothers' preferences with respect to combination vaccines for their children, should new combination vaccines become available that have not yet been launched in Japan or that will be developed in the future. We conducted a web-based, cross-sectional survey of 1,243 mothers who had at least one child between 2 months and 3 y of age. Mothers were recruited from an online survey panel of registered users. Their preferences were elicited using discrete choice experiments, the analyzed main effects model, and interactions using a mixed logit model. Mothers showed a preference for vaccines that prevented multiple diseases, had fewer injections per doctor visit, lower price, and lower risk of adverse events. Respondents valued a reduced risk of adverse events the most among all attributes in this study. The estimated monetary value of the willingness to pay for a 1% reduction in the risk of adverse events was ¥ 92,557 ($ 907). Therefore, if new combination vaccines are introduced, the risk of adverse events after vaccination is an especially important factor for mothers. While the safety of the vaccines themselves is required, health professionals should also inform mothers about the benefits and risks of vaccination, to allay mothers' concerns about vaccine safety.

The identification of adverse events following immunization (AEFI) and their prompt investigation are important to allow a timely and scientifically based response to the users of immunization services. This article presents an analysis of notified AEFI cases between 1999 and 2005 and their temporal association with 2001 yellow fever vaccination campaign, AEFI notification attributed to yellow fever vaccination rose from 0.06 to 1.32 per 100,000 vaccinees in Brazil, between 1998 and 2000. During the 2001 yellow fever mass vaccination campaign held in Juiz de Fora, Brazil, 12 cases of aseptic meningitis were temporally associated to yellow fever vaccination, but clinical and laboratory data were not available to confirm nor deny causality. Epidemiological studies associated to enhanced surveillance and standardized protocols should take advantage of public health interventions like mass vaccination campaigns and implementation of new vaccination strategies in order to assess and investigate vaccine safety.
Should herbs take all the blame? Causality assessment of a serious thrombocytopenia event.

With the increasing use of herbal medicines, the causality assessment of adverse drug-related reactions becomes more complicated because of the concomitant use of herbs and conventional medications. Epidemiological causal inference can be a central feature of such judgment but may be insufficient. Other scientific considerations include study design, bias, confounding, and measurement issues. The approach of this study is to establish an active safety surveillance system for finished herbal products (FHPs) and to review each adverse event regularly. A single case of serious thrombocytopenia was found in 136 subjects taking FHPs on a clinical trial for 12 weeks, for which the cause was sought. Because at the end of the first month the patient's platelet counts were normal and the thrombocytopenia developed after the co-medication with conventional drugs, it was suspected that the thrombocytopenia might not be attributed to the use of FHP. This report summarizes the criteria of causality assessment under mixed use of herbs and conventional medicine and recommends a feasible process for careful evaluation of adverse drug reactions related to all herbal medicine.

When ERCP fails, EUS-guided interventional techniques may be an alternative. The aim of this study was to evaluate the general outcomes and safety of EUS-guided methylene blue cholangiopancreatography in patients with failed ERCP in benign biliopancreatic diseases. Patients with benign biliopancreatic diseases and failed ERCP were included. EUS-guided cholangiopancreatography plus injection of methylene blue was performed, and then ERCP using coloring agent flow as an indicator of papilla orifice was performed. Procedures were prospectively collected in this observational, single-center study. Technical success, clinical success, and adverse events were analyzed retrospectively. Eleven patients were included (10 choledocholithiasis, 1 pancreatic stricture). The main reason for failed ERCP was an unidentifiable papilla. EUS-guided ductal access with cholangiopancreatography and papilla orifice identification was obtained in all cases. Technical success and clinical success rates of 91% were achieved, with successful biliopancreatic drainage in 10 patients. Adverse events included 1 peripancreatic abscess attributed to a precut, which was successfully treated. No adverse events were related to the first EUS-guided stage. EUS-guided cholangiopancreatography with methylene blue injection seems to be a feasible and helpful technique for treatment in patients with benign biliopancreatic diseases with previous failed ERCP because of an undetectable papilla.

Safety of Sports for ICD Patients. The safety of sports participation for patients with implantable cardioverter defibrillators (ICDs) is unknown, and recommendations among physicians may vary widely. The purposes of this study were to determine current practice among patients with ICDs and their physicians regarding sports participation, and to determine how many physicians have cared for patients who have sustained adverse events during sports participation. A survey was mailed to all 1,687 U.S. physician members of the Heart Rhythm Society. Among 614 respondent physicians, recommendations varied widely. Only 10% recommended avoidance of all sports more vigorous than golf. Seventy-six percent recommended avoidance of contact, and 45% recommend avoidance of competitive sports. Most (71%) based restrictions on patients' underlying heart disease. Regardless of recommendations, most physicians (71%) reported caring for patients who participated in sports, including many citing vigorous, competitive sports, most commonly cited were basketball, running, and skiing. ICD shocks during sports were common, cited by 40% of physicians. However, few adverse consequences were reported. One percent of physicians reported known injury to patient (all but 3 minor); 5%, injury to the ICD system, and <1%, failure of shocks to terminate arrhythmia. The most common adverse event reported was lead damage attributed to repetitive-motion activities, most commonly weightlifting and golf. Physician recommendations for sports participation for patients with ICDs varies widely. Many patients with ICDs do participate in vigorous and even competitive sports. While shocks were common, significant adverse events were rare.

Immunization of egg-allergic children against measles, mumps, and rubella (MMR) is often deferred or even denied, although the safety of this vaccination has been clearly shown. Moreover, the majority of severe allergic reactions have occurred in egg-tolerant vaccinees. Other allergenic vaccine components have been sought, and gelatin has been suggested as one cause of allergic adverse events. The aim of this study was to further characterize the actual allergenic vaccine components. Serum samples from 36 recipients of MMR vaccine with anaphylaxis, urticaria with or without angioedema, asthmatic symptoms, or Henoch-Schönlein purpura were analyzed by CAP System radioallergosorbent test (RAST) and immunospot methods to detect the allergenic vaccine component. To evaluate the correspondence between the findings in the CAP System RAST or the immunospot and clinical symptoms, histories of allergies and present hypersensitivity symptoms were assessed. Of the 36 participants, 10 were demonstrated to be allergic to gelatin. Seven of them had persistent allergic symptoms, possibly attributable to foods containing gelatin or cross-reactive allergens. The results of the immunospot suggested concomitant allergy to gelatin and egg, chicken, and feathers, as well as cow's milk, or they reflected allergen cross-reactivity. Although severe allergic adverse events attributable to MMR vaccination are extremely rare, all serious allergic reactions should be further assessed to detect the likely causative vaccine component, including gelatin. The current recommendation for immunization of egg-allergic persons according to standard MMR vaccination schedules is reinforced. measles, mumps, and rubella vaccine, immunization, adverse effects, allergic reactions, gelatin allergy, CAP System, radioallergosorbent test, immunospot, immunoglobulin E.

Excess adverse events may be attributable to poor surgical performance but also to case-mix, which is controlled through the Standardized Incidence Ratio (SIR). SIR calculations can be complicated, resource consuming, and unfeasible in some settings. This article suggests a novel method for SIR approximation. In order to evaluate a potential SIR surrogate measure we predefined acceptance criteria. We developed a new measure - Approximate Risk Index (ARI). "Number Needed for Event" (NNE) is the theoretical number of patients needed "to produce" one adverse event. ARI is defined as the quotient of the group of patients needed for no observed events Ge by total patients treated Ga. Our evaluation compared 2500 surgical units and over 3 million heterogeneous risk surgical patients that were induced through a computerized simulation. Surgical unit's data were computed for SIR and ARI to evaluate compliance with the predefined criteria. Approximation was evaluated by correlation analysis and performance prediction capability by Receiver Operating Characteristics (ROC) analysis. ARI strongly correlates with SIR (r(2) = 0.87, p < 0.05). ARI prediction of excessive risk revealed excellent ROC (Area Under the Curve > 0.9) 87% sensitivity and 91% specificity. ARI provides good approximation of SIR and excellent prediction capability. ARI is simple and cost-effective as it requires thorough risk evaluation of only the adverse events patients. ARI can provide a crucial screening and performance evaluation quality control tool. The ARI method may suit other clinical and epidemiological settings where relatively small fraction of the entire population is affected. Copyright © 2013 Surgical Associates Ltd.

We have applied detection and attribution techniques to the severe drought that hit the Horn of Africa in 2014. The short rains failed in late 2013 in Kenya, South Sudan, Somalia and southern Ethiopia, leading to a very dry growing season January to March 2014, and subsequently to the current drought in many agricultural areas of the sub-region. We have made use of the weather@home project, which uses publicly-volunteered distributed computing to provide a large ensemble of simulations sufficient to sample regional climate uncertainty. Based on this, we have estimated the occurrence rates of the kinds of the rare and extreme events implicated in this large-scale drought. From land surface model runs based on these ensemble simulations, we have estimated the impacts of climate anomalies during this period and therefore we can reliably identify some factors of the ongoing drought as attributable to human-induced climate change. The UNFCCC's Adaptation Fund is attempting to support projects that bring about an adaptation to "the adverse effects of climate change", but in order to formulate such projects we need a much clearer way to assess how much climate change is human-induced and how much is a consequence of climate anomalies and large-scale teleconnections, which can only be provided by robust attribution techniques.
Adverse events in British hospitals: preliminary retrospective record review
Vincent, Charles; Neale, Graham; Woloshynowych, Maria

Objectives To examine the feasibility of detecting adverse events through record review in British hospitals and to make preliminary estimates of the incidence and costs of adverse events. Design Retrospective review of 1014 medical and nursing records. Setting Two acute hospitals in Greater London area. Main outcome measure Number of adverse events. Results 110 (10.8%) patients experienced an adverse event, with an overall rate of adverse events of 11.7% when multiple adverse events were included. About half of these events were judged preventable with ordinary standards of care. A third of adverse events led to moderate or greater disability or death. Conclusions These results suggest that adverse events are a serious source of harm to patients and a large drain on NHS resources. Some are major events; others are frequent, minor events that go unnoticed in routine clinical care but together have massive economic consequences. PMID:11230064

Sirolimus is used in cardiac transplant recipients to prevent rejection, progression of cardiac allograft vasculopathy, and renal dysfunction. However, sirolimus has many potential side effects and its tolerability when used outside of clinical trials is not well established. We describe a decade of experience with sirolimus in cardiac transplant recipients at our institution. We retrospectively reviewed records of all adult cardiac transplant recipients living between September 1999 and February 2010 (n = 329) and identified 67 patients (20%) who received sirolimus. The indications for sirolimus were cardiac allograft vasculopathy (67%), renal dysfunction (25%), rejection (4%), and intolerability of tacrolimus (3%). One-third of patients discontinued sirolimus at a median (25th, 75th percentiles) of 0.9 (0.2, 1.6) yr of duration. Over 70% of subjects experienced an adverse event attributed to sirolimus. Adverse events were associated with higher average sirolimus levels (9.1 ng/mL vs. 7.1 ng/mL, p = 0.004). We conclude that sirolimus is frequently used in cardiac transplant recipients (20%) and commonly causes side effects, often necessitating discontinuation. Higher average sirolimus levels were associated with adverse events, suggesting that tolerability may improve if levels are maintained within the lower end of the current therapeutic range; however, the improvement in tolerability would need to be balanced with the potential for decreased efficacy. © 2013 John Wiley & Sons A/S.

Limited data are available describing donor adverse events (AEs) associated with filgrastim mobilized peripheral blood stem cell (PBSC) collections in unrelated volunteers. We report results in 2408 unrelated PBSC donors prospectively evaluated by the National Marrow Donor Program (NMDP) between 1999 and 2004. Female donors had higher rates of AEs, requiring central line placement more often (17% vs 4%, P < .001), experiencing more apheresis-related AEs (20% vs 7%, P < .001), more bone pain (odds ratio [OR] = 1.49), and higher rates of grades II-IV and III-IV CALGB AEs (OR = 2.22 and 2.32). Obese donors experienced more bone pain (obese vs normal, OR = 1.73) and heavy donors had higher rates of CALGB toxicities (> 95 kg vs < 70 kg, OR = 1.49). Six percent of donors experienced grade III-IV CALGB toxicities and 0.6% experienced toxicities that were considered serious and unexpected. Complete recovery is universal, however, and no late AEs attributable to donation have been identified. In conclusion, PBSC collection in unrelated donors is generally safe, but nearly all donors will experience bone pain, 1 in 4 will have significant headache, nausea, or citrate toxicity, and a small percentage will experience serious short-term adverse events. In addition, women and larger donors are at higher risk for donation-related AEs. PMID:19190248

There is a lack of consensus about whether the initial imaging method for patients with suspected nephrolithiasis should be computed tomography (CT) or ultrasonography. In this multicenter, pragmatic, comparative effectiveness trial, we randomly assigned patients 18 to 76 years of age who presented to the emergency department with suspected nephrolithiasis to undergo initial diagnostic ultrasonography performed by an emergency physician (point-of-care ultrasonography), ultrasonography performed by a radiologist (radiology ultrasonography), or abdominal CT. Subsequent management, including additional imaging, was at the discretion of the physician. We compared the three groups with respect to the 30-day incidence of high-risk diagnoses with complications that could be related to missed or delayed diagnosis and the 6-month cumulative radiation exposure. Secondary outcomes were serious adverse events, related serious adverse events (deemed attributable to study participation), pain (assessed on an 11-point visual-analogue scale, with higher scores indicating more severe pain), return emergency department visits, hospitalizations, and diagnostic accuracy. A total of 2759 patients underwent randomization: 908 to point-of-care ultrasonography, 893 to radiology ultrasonography, and 958 to CT. The incidence of high-risk diagnoses with complications in the first 30 days was low (0.4%) and did not vary according to imaging method. The mean 6-month cumulative radiation exposure was significantly lower in the ultrasonography groups than in the CT group (P<0.001). Serious adverse events occurred in 12.4% of the patients assigned to point-of-care ultrasonography, 10.8% of those assigned to radiology ultrasonography, and 11.2% of those assigned to CT (P=0.50). Related adverse events were infrequent (incidence, 0.4%) and similar across groups. By 7 days, the average pain score was 2.0 in each group (P=0.84). Return emergency department visits, hospitalizations, and diagnostic accuracy did not differ significantly among the groups. Initial ultrasonography was associated with lower cumulative radiation exposure than initial CT, without significant differences in high-risk diagnoses with complications, serious adverse events, pain scores, return emergency department visits, or hospitalizations.

Rhythm- and rate-control therapies are an essential part of atrial fibrillation (AF) management; however, the use of existing agents is often limited by the occurrence of adverse events. The aim of this study was to evaluate suspected adverse events and adverse event monitoring, and associated medical costs, in patients receiving AF rhythm-control and/or rate-control therapy. This retrospective cohort study used claims data from the Integrated Healthcare Information Systems National Managed Care Benchmark Database from 2002-2006. Patients hospitalized for AF (primary diagnosis), and who had at least 365 days' enrollment before and after the initial (index) AF hospitalization, were included in the analysis. Suspected AF therapy-related adverse events and function tests for adverse event monitoring were identified according to pre-specified diagnosis codes/procedures, and examined over the 12 months following discharge from the index hospitalization. Events/function tests had to have occurred within 90 days of a claim for AF therapy to be considered a suspected adverse event/adverse event monitoring. Of 4174 AF patients meeting the study criteria, 3323 received AF drugs; 428 received rhythm-control only (12.9%), 2130 rate-control only (64.1%), and 765 combined rhythm/rate-control therapy (23.0%). Overall, 50.1% of treated patients had a suspected adverse event and/or function test for adverse event monitoring (45.5% with rate-control, 53.5% with rhythm-control, and 61.2% with combined rhythm/rate-control). Suspected cardiovascular adverse events were the most common events (occurring in 36.1% of patients), followed by pulmonary (6.1%), and endocrine events (5.9%). Overall, suspected adverse events/function tests were associated with mean annual per-patient costs of $3089 ($1750 with rhythm-control, $2041 with rate control, and $6755 with combined rhythm/rate-control). As a retrospective analysis, the study is subject to potential selection bias, while its reliance on diagnostic codes for identification of AF and suspected adverse events is a source of potential investigator error. A direct cause-effect relationship between suspected adverse events/function tests and AF therapy cannot be confirmed based on the claims data available. The incidence of suspected adverse events and adverse event monitoring during AF rhythm-control and/or rate-control therapy is high. Costs associated with adverse events and adverse event monitoring are likely to add considerably to the overall burden of AF management.
Nickel-related adverse reactions in the treatment of cerebral aneurysms: a literature review.

Nickel is the most common metal allergen and predominantly affects women. It is also the ubiquitous component in the alloys used to manufacture intracranial devices for aneurysm treatments, including aneurysm clips, self-expanding stents, flow-diverting stents and endosaccular occlusion devices. Adverse events related to nickel-allergy after deployment of such devices are uncommon but can be severe, resulting in dilemmas in the choice of treatment strategies and devices in managing nickel-sensitive patients with intracranial aneurysms. A literature search in accordance with the PRISMA guidelines was performed to identify studies reporting on nickel-related adverse events in cerebral aneurysm treatment. The material of the culprit devices, clinical presentation, histological feature and treatment were reviewed. The clinical consideration and management options for nickel allergy patients were discussed. Nickel is a major component of the cobalt-alloy used in aneurysm clips, and of nitinol which is commonly used in flow-diverters and intracranial stents. There were 9 papers reporting 10 unique cases of nickel-related adverse events after aneurysm treatment. Half of the cases occurred after aneurysm clipping and the remaining 5 was attributed to endovascular devices. Two presented with dermatological and 8 with neurological manifestations including cerebral edema and cerebritis. Neurological complication related to nickel in cerebral aneurysm treatments is rare but remains a concern due to the high prevalence of nickel allergy in the population. Surgeons and interventionists should consider the metal-allergy history and its potential clinical significance in managing nickel-allergic patients with aneurysms. Copyright © 2018 Elsevier Inc.

"Hospital at Home(HaH)" programs provide an alternative to traditional hospitalization. However, the incidence of adverse drug events in these programs is unknown. This study describes adverse drug events and potential adverse drug events in a new HaH program. We examined the charts of the first 50 patients admitted. We found 45 potential adverse drug events and 14 adverse drug events from admission to 30 days after HaH discharge. None of the adverse drug events were severe. Some events, like problems with medication administration, may be unique to the hospital at home setting. Monitoring for adverse drug events is feasible and important for hospital at home programs.

Understanding the nature and causes of medical adverse events may help their prevention. This systematic review explores the types, risk factors, and likely causes of preventable adverse events in the hospital sector. MEDLINE (1970-2008), EMBASE, CINAHL (1970-2005) and the reference lists were used to identify the studies and a structured narrative method used to synthesise the data. Operative adverse events were more common but less preventable and diagnostic adverse events less common but more preventable than other adverse events. Preventable adverse events were often associated with more than one contributory factor. The majority of adverse events were linked to individual human error, and a significant proportion of these caused serious patient harm. Equipment failure was involved in a small proportion of adverse events and rarely caused patient harm. The proportion of system failures varied widely ranging from 3% to 85% depending on the data collection and classification methods used. Operative adverse events are more common but less preventable than diagnostic adverse events. Adverse events are usually associated with more than one contributory factor, the majority are linked to individual human error, and a proportion of these with system failure.

Accident reports provide important insights into the causes and contributory factors leading to particular adverse events. In contrast, this paper provides an analysis that extends across the findings presented over ten years investigations into maritime accidents by both the US National Transportation Safety Board (NTSB) and Canadian Transportation Safety Board (TSB). The purpose of the study was to assess the comparative frequency of a range of causal factors in the reporting of adverse events. In order to communicate our findings, we introduce J-H graphs as a means of representing the proportion of causes and contributory factors associated with human error, equipment failure and other high level classifications in longitudinal studies of accident reports. Our results suggest the proportion of causal and contributory factors attributable to direct human error may be very much smaller than has been suggested elsewhere in the human factors literature. In contrast, more attention should be paid to wider systemic issues, including the managerial and regulatory context of maritime operations.

To use a case-time-control design to derive preliminary estimates of unplanned hospitalisations attributable to suspected high-risk medications in elderly Western Australians. Using pharmaceutical claims linked to inpatient and other health records, the study applied a case-time-control design and conditional logistic regression to estimate odds ratios (ORs) for unplanned hospital admissions associated with anticoagulants, antirheumatics, opioids, corticosteroids and four major groups of cardiovascular drugs. Attributable fractions (AFs) were derived from the ORs to estimate the number and proportion of admissions associated with drug exposure. Results were compared with those obtained from a more conventional method using International Classification of Diseases (ICD) external cause codes to identify admissions related to adverse drug events. The study involved 1 899 699 index hospital admissions. Six of the eight drug groups were associated with an increased risk of unplanned hospitalisation, opioids (adjusted OR = 1.81, 95%CI 1.75-1.88; AF = 44.9%) and corticosteroids (1.48, 1.42-1.54; 32.2%) linked with the highest risks. For all six, the estimated number of hospitalisations attributed to the medication in the exposed was higher (two to 31-fold) when derived from the case-time-control design compared with identification from ICD codes. This study provides an alternative approach for identifying potentially harmful medications and suggests that the use of ICD external causes may underestimate adverse drug events. It takes drug exposure into account, can be applied to individual medications and may overcome under-reporting issues associated with conventional methods. The approach shows great potential as part of a post-marketing pharmacovigilance monitoring system in Australia and elsewhere. Copyright © 2013 John Wiley & Sons, Ltd.

In the final analysis of the phase 3 COU-AA-301 study, abiraterone acetate plus prednisone significantly prolonged overall survival compared with prednisone alone in patients with metastatic castration-resistant prostate cancer progressing after chemotherapy. Here, we present the final analysis of an early-access protocol trial that was initiated after completion of COU-AA-301 to enable worldwide preapproval access to abiraterone acetate in patients with metastatic castration-resistant prostate cancer progressing after chemotherapy. We did a multicentre, open-label, early-access protocol trial in 23 countries. We enrolled patients who had metastatic castration-resistant prostate cancer progressing after taxane chemotherapy. Participants received oral doses of abiraterone acetate (1000 mg daily) and prednisone (5 mg twice a day) in 28-day cycles until disease progression, development of sustained side-effects, or abiraterone acetate becoming available in the respective country. The primary outcome was the number of adverse events arising during study treatment and within 30 days of discontinuation. Efficacy measures (time to prostate-specific antigen [PSA] progression and time to clinical progression) were gathered to guide treatment decisions. We included in our analysis all patients who received at least one dose of abiraterone acetate. This study is registered with ClinicalTrials.gov, number NCT01217697. Between Nov 17, 2010, and Sept 30, 2013, 2314 patients were enrolled into the early-access protocol trial. Median follow-up was 5·7 months (IQR 3·5-10·6). 952 (41%) patients had a grade 3 or 4 treatment-related adverse event, and grade 3 or 4 serious adverse events were recorded in 585 (25%) people. The most common grade 3 and 4 adverse events were hepatotoxicity (188 [8%]), hypertension (99 [4%]), cardiac disorders (52 [2%]), osteoporosis (31 [1%]), hypokalaemia (28 [1%]), and fluid retention or oedema (23 [1%]). 172 (7%) patients discontinued the study because of adverse events (64 [3%] were drug-related), as assessed by the investigator, and 171 (7%) people died. The funder assessed causes of death, which were due to disease progression (85 [4%]), an unrelated adverse experience (72 [3%]), and unknown reasons (14 [1%]). Of the 86 deaths not attributable to disease progression, 18 (<1%) were caused by a drug-related adverse event, as assessed by the investigator. Median time to PSA progression was 8·5 months (95% CI 8·3-9·7) and median time to clinical progression was 12·7 months (11·8-13·8). No new safety signals or unexpected adverse events were found in this early-access protocol trial to assess abiraterone acetate for patients with metastatic castration-resistant prostate cancer who progressed after chemotherapy. Future work is needed to ascertain the most effective regimen of abiraterone acetate to optimise patients' outcomes. Janssen Research & Development. Copyright © 2014 Elsevier Ltd.

Safety in the operating room is widely debated. Adverse events during surgery are potentially dangerous for the patient and staff. The incidence of adverse events during orthopedic trauma surgery is unknown. Therefore, we performed a study to quantify the incidence of these adverse events. Primary objective was to determine the incidence of adverse events related to technical equipment and logistics. The secondary objective was to evaluate the consequences of these adverse events. We completed a cross-sectional observational study to assess the incidence, consequences and preventability of adverse events related to technical equipment and logistics during orthopedic trauma surgery. During a 10 week period, all orthopedic trauma operations were evaluated by an observer. Six types of procedures were differentiated: osteosynthesis; arthroscopy; removal of hardware; joint replacement; bone grafting and other. Adverse events were divided in six categories: staff dependent factors; patient dependent factors; anaesthesia; imaging equipment; operation room equipment and instruments and implants. Adverse events were defined as any factor affecting the surgical procedure in a negative way. Hundred-fifty operative procedures were included. In 54% of the procedures, at least one adverse event occurred. In total, 147 adverse events occurred, with a range of 1-5 per procedure. Most adverse events occurred during joint replacement procedures. Thirty-seven percent of the incidents concerned defect, incorrect connected or absent instruments. In 36% of the procedures adverse events resulted in a prolonged operation time with a median prolongation of 10.0 min. In more than half of orthopedic trauma surgical procedures adverse events related to technical equipment and logistics occurred, most of them could easily be prevented. These adverse events could endanger the safety of the patient and staff and should therefore be reduced. 4.

Purpose Disproportionality methods measure how unexpected the observed number of adverse events is. Time-to-onset (TTO) methods measure how unexpected the TTO distribution of a vaccine-event pair is compared with what is expected from other vaccines and events. Our purpose is to compare the performance associated with each method. Methods For the disproportionality algorithms, we defined 336 combinations of stratification factors (sex, age, region and year) and threshold values of the multi-item gamma Poisson shrinker (MGPS). For the TTO algorithms, we defined 18 combinations of significance level and time windows. We used spontaneous reports of adverse events recorded for eight vaccines. The vaccine product labels were used as proxies for true safety signals. Algorithms were ranked according to their positive predictive value (PPV) for each vaccine separately; amedian rank was attributed to each algorithm across vaccines. Results The algorithm with the highest median rank was based on TTO with a significance level of 0.01 and a time window of 60 days after immunisation. It had an overall PPV 2.5 times higher than for the highest-ranked MGPS algorithm, 16th rank overall, which was fully stratified and had a threshold value of 0.8. A TTO algorithm with roughly the same sensitivity as the highest-ranked MGPS had better specificity but longer time-to-detection. Conclusions Within the scope of this study, the majority of the TTO algorithms presented a higher PPV than for any MGPS algorithm. Considering the complementarity of TTO and disproportionality methods, a signal detection strategy combining them merits further investigation. PMID:24038719

In order to evaluate the safety of acupuncture in China objectively, we investigated the adverse events associated with acupuncture based on three multicentre randomized controlled trials (RCTs) to assess the safety of acupuncture, identifying the common types of acupuncture adverse events, and analysing the related risk factors for their occurrence. This observational study included patients who received acupuncture from three multicentre RCTs respectively for migraine, functional dyspepsia and Bell's palsy. The 1968 patients and their acupuncturists documented adverse events associated with acupuncture after treatment. We collected data about adverse events due to acupuncture treatment from their case report forms. We analysed the incidence and details of the adverse effects, and studied the risk factors for acupuncture adverse events with non-conditional logistic regression analysis. Among the 1968 patients, 74 patients (3.76%) suffered at least one adverse event throughout the treatment period. We did not observe the occurrence of serious adverse events. 73 patients with adverse events recovered within 2 weeks through effective treatment such as physiotherapy or self-treatment. A total of 3 patients withdrew because of adverse events. There were 9 types of adverse events related to acupuncture, including subcutaneous haematoma, bleeding, skin bruising and needle site pain. Subcutaneous haematoma and haemorrhage in the needling points were the most common adverse events. Age and gender were related to the occurrence of acupuncture adverse events. The older the patients were, the higher the risk of adverse events was. In addition, male patients had slightly higher risk of an adverse event than female patients. Acupuncture is a safe therapy with low risk of adverse events in clinical practice. The risk factors for adverse events (AEs) were related to the patients' gender and age and the local anatomical structure of the acupoints. AEs could be reduced and mitigated by improving the medical environment, ensuring a high technical level of the acupuncture practitioners and establishing a good relationship of mutual trust between doctor and patient.

Retrospective, descriptive analysis. To describe the prevalence and nature of insurance claims for injuries attributed to physiotherapy care. In New Zealand, a national insurance scheme, the Accident Compensation Corporation, provides comprehensive, no-fault personal injury coverage. The patterns of injury sustained during physiotherapy care have not previously been described. De-identified data for all injuries registered with the Accident Compensation Corporation from 2005 to 2010 and attributed to physiotherapy were accessed. Prevalence patterns (percentages) of new-claim data were determined for physiotherapy intervention category, injury site, nature of injury, age, and sex. A subcategory, exercise-related injuries, was analyzed according to injury site and whether the injury was related (primary) or unrelated (secondary) to the intended therapeutic goal. There were 279 claims related to physiotherapy care filed with the Accident Compensation Corporation during the studied reporting period. Injury was attributed predominantly to exercise (n = 88, 31.5% of cases) and manual therapy (n = 74, 26.5% of cases). The prevalence of events categorized as exercise related was greatest in those who were 55 to 59 years of age (n = 14, 16.3%) and greater in females (n = 47, 54.7%). Of the exercise-related injuries, 39.8% were in the lower-limb region and 35.2% were categorized as sprains/strains. Injuries attributed to exercise exceeded those linked to other therapies provided by physiotherapists, yet exercise therapy rarely features as a cause of adverse events reported to the physiotherapy profession. The proportion of exercise-related injury events underlines the need for ensuring safe and careful consideration of exercise prescription. Harm, level 4.

Absolute neutrophil counts (ANCs) are lower in East African adults. To assess the impact of lower ANCs, we reviewed data from HIV-infected Kenyan women receiving antiretroviral therapy antepartum and postpartum. The Kisumu Breastfeeding Study (KiBS) participants received an antiretroviral regimen from 34 weeks' gestation through 6 months postpartum. Measured ANCs and subsequent illnesses were reviewed. Adverse events (AEs) potentially attributable to neutropenia were identified, and ANCs were graded using the 2004 Division of AIDS table for Grading the Severity of AEs. Among 478 women with ≥1 postpartum ANC measured, 298 (62.1%) women met criteria for an AE (<1.3 × 10(9) cells/L). Of those, 38 (12.5%) women experienced a nonlife-threatening illness potentially attributable to neutropenia. More than half of KiBS women met criteria for neutropenia. The mild clinical experience of most participants with low ANCs supports that these values might be typical for this population and may not result in adverse clinical sequelae. © The Author(s) 2013.

Successful control of blood pressure relies on identification of secondary causes and contributing factors of hypertension. As antihypertensive medication can interfere with diagnostic investigations, temporary discontinuation of medication is advised. However, there are concerns about the safety of temporary discontinuation of antihypertensive medication in patients with difficult-to-control hypertension. We assessed the occurrence of adverse cardiovascular and cerebrovascular events potentially attributable to temporary discontinuation of antihypertensive medication between February 2010 and March 2016 (n=604) in our Analysis of Complicated Hypertension screening program. A reference group (n=604) was extracted from the SMART study (Second Manifestations of Arterial Disease) cohort (comprising a similar cohort at our hospital in whom medication was not stopped) and individually matched for blood pressure, age, sex, and history of cardiovascular disease. Discontinuation of medication was well tolerated; 62% reported no complaints, 24% had mild discomfort that could be left untreated, and 14% experienced complaints that required prescription of antihypertensive escape medication. Three major adverse events were observed in the Analysis of Complicated Hypertension group between discontinuation of medication and 30 days after restart of medication (event rate=31.2 events per 1000 patient-year). In the reference cohort, 5 cardiovascular events were observed during a similar follow-up period (event rate=51.2 events per 1000 patient-year). In conclusion, discontinuation of antihypertensive medication for the diagnostic evaluation of hypertension does not increase the acute risk of cardiovascular events when performed in a well-controlled setting in specialized hospitals with appropriate protocols for monitoring safety. © 2017 American Heart Association, Inc.
Smoking and Adverse Maternal and Child Health Outcomes in Brazil
2013-01-01
Introduction: Numerous studies from high-income countries document the causal relationship between cigarette smoking during pregnancy and adverse maternal and child health (MCH) outcomes. Less research has been conducted in low and middle income countries, but a burgeoning literature can be found for Brazil. Methods: We review Brazilian studies of the prevalence of maternal smoking, the relative risk of smoking-attributable adverse MCH outcomes, and present new estimates for these outcomes, using the attributable fraction method. Results: We found that Brazilian studies of the relative risks of smoking-attributable adverse MCH outcomes were broadly consistent with previous reviews. Based on a comparison of maternal smoking over time, smoking during pregnancy has declined by about 50% over the last 20 years in Brazil. For 2008, we estimate that 5,352 cases of spontaneous abortion, 10,929 cases of preterm birth, 20,717 cases of low birth weight, and 29 cases of sudden infant death syndrome are attributable to maternal smoking. Between 1989 and 2008, the percent of smoking-attributable adverse MCH outcomes in Brazil was at least halved. Conclusions: The results show that over a 20-year period, during which Brazil implemented numerous effective tobacco control measures, the country experienced a dramatic decrease in both maternal smoking prevalence and smoking-attributable adverse MCH outcomes. Countries that implement effective tobacco control measures can expect to reduce both maternal smoking and adverse MCH outcomes, thereby improving the public health. PMID:23873977

Conventional practice monitors accumulating information about drug safety in terms of the numbers of adverse events reported from trials in a drug development program. Estimates of between-treatment adverse event risk differences can be obtained readily from unblinded trials with adjustment for differences among trials using conventional statistical methods. Recent regulatory guidelines require monitoring the cumulative frequency of adverse event reports to identify possible between-treatment adverse event risk differences without unblinding ongoing trials. Conventional statistical methods for assessing between-treatment adverse event risks cannot be applied when the trials are blinded. However, CUSUM charts can be used to monitor the accumulation of adverse event occurrences. CUSUM charts for monitoring adverse event occurrence in a Bayesian paradigm are based on assumptions about the process generating the adverse event counts in a trial as expressed by informative prior distributions. This article describes the construction of control charts for monitoring adverse event occurrence based on statistical models for the processes, characterizes their statistical properties, and describes how to construct useful prior distributions. Application of the approach to two adverse events of interest in a real trial gave nearly identical results for binomial and Poisson observed event count likelihoods.

Early life events are studied as potential causes of cancer. The objective here was to study childhood adversities in the etiology of cancer. The material comprised a population based random sample of 25 898 individuals among the Finnish working-aged population. In 1998 they were requested through six questions in a postal questionnaire to recall their childhood adversities. The cases consisted of people with cancer diagnosed 2000-2006 and registered in the Finnish Cancer Registry (n = 384). The rest of the sample consisted of cancer-free controls. The most common adversities were prolonged financial difficulties, serious conflicts in the family and someone in the family having been seriously or chronically ill. The cancer patients reported more prolonged financial difficulties and someone seriously or chronically ill in the family. They reported less parental divorce than the controls. The associations were not statistically significant after adjusting for age, sex, education, and health behaviour. Nor was there a significant difference in the total number of childhood adversities between the study group and the controls. On the whole, these cancer patients had not experienced more childhood adversities than the controls. According to our findings, there is no cause to attribute development of cancer in working age to childhood adversities. This information may also give relief to other family members.

To identify the rate of serious adverse events attributable to yellow fever vaccination with 17D and 17DD strains reported in active and passive surveillance data. We conducted a systematic review of published literature on adverse events associated with yellow fever. We searched 9 electronic databases for peer reviewed and grey literature in all languages. There were no restrictions on date of publication. Reference lists of key studies were also reviewed to identify additional studies. We identified 66 relevant studies: 24 used active, 17 a combination of passive and active (15 of which were pharmacovigilance databases), and 25 passive surveillance. ACTIVE SURVEILLANCE: A total of 2,660,929 patients in general populations were followed for adverse events after vaccination, heavily weighted (97.7%) by one large Brazilian study. There were no observed cases of viscerotropic or neurotropic disease, one of anaphylaxis and 26 cases of urticaria (hypersensitivity). We also identified four studies of infants and children (n=2199), four studies of women (n=1334), and one study of 174 HIV+, and no serious adverse events were observed. PHARMACOVIGILANCE DATABASES: 10 of the 15 databases contributed data to this review, with 107,621,154 patients, heavily weighted (94%) by the Brazilian database. The estimates for Australia were low at 0/210,656 for "severe neurological disease" and 1/210,656 for YEL-AVD, and also low for Brazil with 9 hypersensitivity events, 0.23 anaphylactic shock events, 0.84 neurologic syndrome events and 0.19 viscerotropic events cases/million doses. The five analyses of partly overlapping periods for the US VAERS database provided an estimate of 6.6 YEL-AVD and YEL-AND cases per million, and estimates between 11.1 and 15.6 of overall "serious adverse events" per million. The estimates for the UK were higher at 34 "serious adverse events" and also for Switzerland with 14.6 "neurologic events" and 40 "serious events not neurological"/million doses. PASSIVE SURVEILLANCE: Six studies of campaigns in general populations included 94,500,528 individuals, very heavily weighted (99%) by the Brazilian data, and providing an estimate of 0.51 serious AEFIs/million doses. Five retrospective reviews of hospital or clinic records included 60,698 individuals, and no serious AEFIs were proven. The data are heavily weighted (96%) by the data from the Hospital for Tropical Diseases, London. Two studies included 35,723 children, four studies included 138 pregnant women, six studies included 191 HIV+ patients, and there was one review of patients who were HIV+, and no serious AEFIs were proven. The databases in each country used different definitions, protocols, surveillance mechanisms for the initial identification and reporting of cases, and strategies for the clinical and laboratory follow up of cases. The pharmacovigilance databases provide three sets of estimates: a low estimate from the Brazilian and Australian data, a medium estimate from the US VAERS data, and a higher estimate from the UK and Swiss data. The estimates from the active surveillance data are lower (and strongly influenced by the Brazilian data) and the estimates from the passive surveillance studies are also lower (strongly influenced by the London Hospital for Tropical Diseases data from the early 1950s). Sophisticated pathology, histopathology and tests such as PCR amplicon sequencing are needed to prove that serious adverse events were actually caused by the yellow fever vaccine, and the availability of such diagnostic capability is strongly biased towards recent reports from developed countries. Despite these variations in the estimation of serious harm, overall the 17D and 17DD yellow fever vaccine has proven to be a very safe vaccine and is highly effective against an illness with high potential mortality rates.

Pharmacy student perceptions of adverse event reporting.
Kalari, Sirisha; Dormarunno, Matthew; Zvenigorodsky, Oleg; Mohan, Aparna
2011-09-10
To assess US pharmacy students' knowledge and perceptions of adverse event reporting. To gauge pharmacy students' impressions of adverse event reporting, a 10-question survey instrument was administered that addressed student perceptions of the reporting procedures of the Food and Drug Administration (FDA) and pharmaceutical manufacturers, as well as student understanding of the Health Insurance Portability and Accountability Act (HIPAA) and its relationship to adverse event reporting. Two hundred twenty-eight pharmacy students responded to the survey. The majority of respondents believed that the FDA is more likely than a pharmaceutical company to take action regarding an adverse event. There were misconceptions relating to the way adverse event reports are handled and the influence of HIPAA regulations on reporting. Communication between the FDA and pharmaceutical manufacturers regarding adverse event reports is not well understood by pharmacy students. Education about adverse event reporting should evolve so that by the time pharmacy students become practitioners, they are well acquainted with the relevance and importance of adverse event reporting.

A medical intervention is a medical procedure or application intended to relieve or prevent illness or injury. Examples of medical interventions include vaccination and drug administration. After a medical intervention, adverse events (AEs) may occur which lie outside the intended consequences of the intervention. The representation and analysis of AEs are critical to the improvement of public health. The Ontology of Adverse Events (OAE), previously named Adverse Event Ontology (AEO), is a community-driven ontology developed to standardize and integrate data relating to AEs arising subsequent to medical interventions, as well as to support computer-assisted reasoning. OAE has over 3,000 terms with unique identifiers, including terms imported from existing ontologies and more than 1,800 OAE-specific terms. In OAE, the term 'adverse event' denotes a pathological bodily process in a patient that occurs after a medical intervention. Causal adverse events are defined by OAE as those events that are causal consequences of a medical intervention. OAE represents various adverse events based on patient anatomic regions and clinical outcomes, including symptoms, signs, and abnormal processes. OAE has been used in the analysis of several different sorts of vaccine and drug adverse event data. For example, using the data extracted from the Vaccine Adverse Event Reporting System (VAERS), OAE was used to analyse vaccine adverse events associated with the administrations of different types of influenza vaccines. OAE has also been used to represent and classify the vaccine adverse events cited in package inserts of FDA-licensed human vaccines in the USA. OAE is a biomedical ontology that logically defines and classifies various adverse events occurring after medical interventions. OAE has successfully been applied in several adverse event studies. The OAE ontological framework provides a platform for systematic representation and analysis of adverse events and of the factors (e.g., vaccinee age) important for determining their clinical outcomes.

Adverse event (AE) rates in General Surgery vary, according to different authors and recording methods, between 2% and 30%. Six years ago we designed a prospective AE recording system to change patient safety culture in our Department. We present the results of this work after a 6 year follow-up. The AE, sequelae and health care errors in a University Hospital surgery department were recorded. An analysis of each incident recorded was performed by a reviewer. The data was entered into data base for rapid access and consultation. The results were routinely presented in Departmental morbidity-mortality sessions. A total of 13,950 patients had suffered 11,254 AE, which affected 5142 of them (36.9% of admissions). A total of 920 patients were subjected to at least one health care error (6.6% of admissions). This meant that 6.6% of our patients suffered an avoidable AE. The overall mortality at 5 years in our department was 2.72% (380 deaths). An adverse event was implicated in the death of the patient in 180 cases (1.29% of admissions). In 49 cases (0.35% of admissions), mortality could be attributed to an avoidable AE. After 6 years there tends to be an increasingly lower incidence of errors. The exhaustive and prospective recording of AE leads to changes in patient safety culture in a Surgery Department and helps decrease the incidence of health care errors. Copyright © 2011 AEC.

Adverse sensitivity (e.g., allergy and intolerance) information is a critical component of any electronic health record system. While several standards exist for structured entry of adverse sensitivity information, many clinicians record this data as free text. This study aimed to 1) identify and compare the existing common adverse sensitivity information models, and 2) to evaluate the coverage of the adverse sensitivity information models for representing allergy information on a subset of inpatient and outpatient adverse sensitivity clinical notes. We compared four common adverse sensitivity information models: Health Level 7 Allergy and Intolerance Domain Analysis Model, HL7-DAM; the Fast Healthcare Interoperability Resources, FHIR; the Consolidated Continuity of Care Document, C-CDA; and OpenEHR, and evaluated their coverage on a corpus of inpatient and outpatient notes (n = 120). We found that allergy specialists' notes had the highest frequency of adverse sensitivity attributes per note, whereas emergency department notes had the fewest attributes. Overall, the models had many similarities in the central attributes which covered between 75% and 95% of adverse sensitivity information contained within the notes. However, representations of some attributes (especially the value-sets) were not well aligned between the models, which is likely to present an obstacle for achieving data interoperability. Also, adverse sensitivity exceptions were not well represented among the information models. Although we found that common adverse sensitivity models cover a significant portion of relevant information in the clinical notes, our results highlight areas needed to be reconciled between the standards for data interoperability.

Psychotropic drugs are prescribed to approximately 30-40% of adults with intellectual disability (ID) and challenging behaviour, despite the limited evidence of effectiveness and the potential of adverse events. To assess the prevalence of adverse events in association with psychotropic drug use in adults with ID and challenging behaviour and to examine the relation of these adverse events with the person's quality of life. The presence of adverse events was measured with a questionnaire that had to be filled in by the physicians of the participants. Movement disorders were measured separately with a standardised protocol. The strength of the association between adverse events and Intellectual Disability Quality of Life-16 (IDQOL-16), and daily functioning was investigated using linear regression analyses, taking into account the severity of disease (CGI-S) as potential confounder. Virtually all of 103 adults with ID and challenging behaviour had at least one adverse event (84.4%) and almost half had ≥3 adverse events (45.6%) across different subclasses. Using psychotropic drugs increased the prevalence of adverse events significantly. Respectively 13% of the patients without psychotropic drugs and 61% of the patients with ≥2 psychotropic drugs had ≥3 adverse events. Having adverse events had a significantly negative influence on the quality of life. A large majority of all patients had at least one adverse event associated with psychotropic drug use. More attention is needed for these adverse events and their negative influence on the quality of life of these patients, taking into account the lack of evidence of effectiveness of psychotropic drugs for challenging behaviour.

Adverse events are relatively common in healthcare, leading to extensive harm to patients and a significant drain on healthcare resources. Identifying the extent, nature and consequences of adverse events is an important step in preventing adverse events and their consequences which is the subject of this study. This is a retrospective review of medical records randomly selected from patients admitted to 4 general hospitals, staying more than 24 hours and discharged between April and September 2012. We randomly selected 1200 records and completed the record review for 1162 of these records. Standard forms (RF1 and RF2) were used to review medical records in two stages by nurses and medical doctors. Eighty-five (7.3%) of the 1162 records had an adverse event during the admission; and in 43 (3.7%) of the 1162 records, the patient was admitted to the hospital due to an adverse event that occurred before the admission. Therefore, a total of 128 (11.0%) adverse events occurred in 126 (10.9) records as two patients had more than one adverse event. Forty-four (34.3%) of these 128 adverse events were considered preventable. This study confirms that adverse events, particularly adverse drug reactions, post-operative infections, bedsore and hospital acquired infections are common and potentially preventable sources of harm to patients in Iranian hospitals.

The safety of the manual treatment techniques such as spinal manipulation has been discussed and there is a need for more information about potential adverse events after manual therapy. The aim of this randomized controlled trial was to investigate differences in occurrence of adverse events between three different combinations of manual treatment techniques used by manual therapists (i.e. chiropractors, naprapaths, osteopaths, physicians and physiotherapists) for patients seeking care for back and/or neck pain. In addition women and men were compared regarding the occurrence of adverse events. Participants were recruited among patients, ages 18-65, seeking care at the educational clinic of the Scandinavian College of Naprapathic Manual Medicine in Stockholm. The patients (n = 767) were randomized to one of three treatment arms 1) manual therapy (i.e. spinal manipulation, spinal mobilization, stretching and massage) (n = 249), 2) manual therapy excluding spinal manipulation (n = 258) and 3) manual therapy excluding stretching (n = 260). Treatments were provided by students in the seventh semester of total eight. Adverse events were measured with a questionnaire after each return visit and categorized in to five levels; 1) short minor, 2) long minor, 3) short moderate, 4) long moderate and 5) serious adverse events, based on the duration and/or severity of the event. Generalized estimating equations were used to examine the association between adverse event and treatments arms. The most common adverse events were soreness in muscles, increased pain and stiffness. No differences were found between the treatment arms concerning the occurrence of adverse event. Fifty-one percent of patients, who received at least three treatments, experienced at least one adverse event after one or more visits. Women more often had short moderate adverse events (OR = 2.19 (95% CI: 1.52-3.15)), and long moderate adverse events (OR = 2.49 (95% CI: 1.77-3.52)) compared to men. Adverse events after manual therapy are common and transient. Excluding spinal manipulation or stretching do not affect the occurrence of adverse events. The most common adverse event is soreness in the muscles. Women reports more adverse events than men. This trial was registered in a public registry (Current Controlled Trials) (ISRCTN92249294).

Hypersensitivity disorders following vaccinations are a cause for concern. To determine the type and rate by age, gender, and vaccine received for reported hypersensitivity reactions following monovalent 2009 pandemic influenza A (H1N1) vaccines. A systematic review of reports to the Vaccine Adverse Event Reporting System (VAERS) following monovalent 2009 pandemic influenza A (H1N1) vaccines. US Civilian reports following vaccine received from October 1, 2009 through May 31, 2010. Age, gender, vaccines received, diagnoses, clinical signs, and treatment were reviewed by nurses and physicians with expertise in vaccine adverse events. A panel of experts, including seven allergists reviewed complex illnesses and those with conflicting evidence for classification of the event. Of 1984 reports, 1286 were consistent with immediate hypersensitivity disorders and 698 were attributed to anxiety reactions, syncope, or other illnesses. The female-to-male ratio was ≥4:1 for persons 20-to-59 years of age, but approximately equal for children under 10. One hundred eleven reports met Brighton Collaboration criteria for anaphylaxis; only one-half received epinephrine for initial therapy. The overall rate of reported hypersensitivity reactions was 10.7 per million vaccine doses distributed, with a 2-fold higher rate for live vaccine. Underreporting, especially of mild events, would result in an underestimate of the true rate of immediate hypersensitivity reactions. Selective reporting of events in adult females could have resulted in higher rates than reported for males. Adult females may be at higher risk of hypersensitivity reactions after influenza vaccination than men. Although the risk of hypersensitivity reactions following 2009 pandemic influenza A (H1N1) vaccines was low, all clinics administering vaccines should be familiar with treatment guidelines for these adverse events, including the use of intramuscular epinephrine early in the course of serious hypersensitivity reactions.

Reporting of adverse events in randomized clinical trials (RCTs) is encouraged by the authors of The Consolidated Standards of Reporting Trials (CONSORT) statement. With robust methodological design and adequate reporting, RCTs have the potential to provide useful evidence on the incidence of adverse events associated with spinal manipulative therapy (SMT). During a previous investigation, it became apparent that comprehensive search strategies combining text words with indexing terms was not sufficiently sensitive for retrieving records that were known to contain reports on adverse events. The aim of this analysis was to compare the proportion of articles containing data on adverse events associated with SMT that were indexed in MEDLINE and/or EMBASE and the proportion of those that included adverse event-related words in their title or abstract. A sample of 140 RCT articles previously identified as containing data on adverse events associated with SMT was used. Articles were checked to determine if: (1) they had been indexed with relevant terms describing adverse events in the MEDLINE and EMBASE databases; and (2) they mentioned adverse events (or any related terms) in the title or abstract. Of the 140 papers, 91% were MEDLINE records, 85% were EMBASE records, 81% were found in both MEDLINE and EMBASE records, and 4% were not in either database. Only 19% mentioned adverse event-related text words in the title or abstract. There was no significant difference between MEDLINE and EMBASE records in the proportion of available papers (p = 0.078). Of the 113 papers that were found in both MEDLINE and EMBASE records, only 3% had adverse event-related indexing terms assigned to them in both databases, while 81% were not assigned an adverse event-related indexing term in either database. While there was effective indexing of RCTs involving SMT in the MEDLINE and EMBASE databases, there was a failure of allocation of adverse event indexing terms in both databases. We recommend the development of standardized definitions and reporting tools for adverse events associated with SMT. Adequate reporting of adverse events associated with SMT will facilitate accurate indexing of these types of manuscripts in the databases.
The reasons for Chinese nursing staff to report adverse events: a questionnaire survey.
Hong, Su; Li, QiuJie
2017-04-01
To investigate the impact of nurses' perception of patient safety culture and adverse event reporting, and demographic factors on adverse event reporting in Chinese hospitals. Accurate and timely adverse event reporting is integral in promoting patient safety and professional learning around the incident. In a cross-sectional survey, a sample of 919 nurses completed a structured questionnaire composed of two validated instruments measuring nurses' perception of patient safety culture and adverse event reporting. Associations between the variables were examined using multiple linear regression analysis. The positive response rates of five dimensions of the Patient Safety Culture Assessment Scale varied from 47.55% to 80.62%. The accuracy rate of Adverse Event Reporting Perception Scale was 63.16%. Five hundred and thirty-one (58.03%) nurses did not report adverse event in past 12 months. Six variables were found to be associated with nurses' adverse event reporting: total work experience (P = 0.003), overall patient safety culture score (P < 0.001), safety climate (P < 0.001), teamwork climate (P < 0.001), overall the adverse event reporting perception scale score (P = 0.003) and importance or reporting (P = 0.002). The results confirmed that improvements in the patient safety culture and nurses' perception of adverse event reporting were related to an increase in voluntary adverse event reporting. The knowledge of adverse event reporting should be integrated into the patient safety curriculum. Interventions that target a specific domain are necessary to improve the safety culture. © 2017 John Wiley & Sons Ltd.
Childhood Adversity and Pain Sensitization.
You, Dokyoung Sophia; Meagher, Mary W
Childhood adversity is a vulnerability factor for chronic pain. However, the underlying pain mechanisms influenced by childhood adversity remain unknown. The aim of the current study was to evaluate the impact of childhood adversity on dynamic pain sensitivity in young adults. After screening for childhood adverse events and health status, healthy individuals reporting low (below median; n = 75) or high levels of adversity (the top 5%; n = 51) were invited for pain testing. Both groups underwent heat pain threshold and temporal summation of second pain (TSSP) testing after reporting depressive symptoms. TSSP refers to a progressive increase in pain intensity with repetition of identical noxious stimuli and is attributed to central sensitization. Changes in pain ratings over time (slope) were computed for TSSP sensitization and decay of subsequent aftersensations. The high-adversity group showed greater TSSP sensitization (meanslope, 0.75; SDpositive slope, 1.78), and a trend toward a slower decay (meanslope, -11.9; SD, 3.4), whereas the low-adversity group showed minimal sensitization (meanslope, 0.07; SDnear-zero slope, 1.77), F(1,123) = 5.84, p = .017 and faster decay (meanslope, -13.1; SD, 3.4), F(1,123) = 3.79, p = .054. This group difference remained significant even after adjusting for adult depressive symptoms (p = .033). No group difference was found in heat pain threshold (p = .85). Lastly, the high-adversity group showed blunted cardiac and skin conductance responses. These findings suggest that enhancement of central sensitization may provide a mechanism underlying the pain hypersensitivity and chronicity linked to childhood adversity.

Yellow fever vaccine provides long-lasting immunity. Rare serious adverse events after vaccination include neurologic or viscerotropic syndromes or anaphylaxis. We conducted a systematic review of adverse events associated with yellow fever vaccination in vulnerable populations. Nine electronic bibliographic databases and reference lists of included articles were searched. Electronic databases identified 2,415 abstracts for review, and 32 abstracts were included in this review. We identified nine studies of adverse events in infants and children, eight studies of adverse events in pregnant women, nine studies of adverse events in human immunodeficiency virus-positive patients, five studies of adverse events in persons 60 years and older, and one study of adverse events in individuals taking immunosuppressive medications. Two case studies of maternal-neonate transmission resulted in serious adverse events, and the five passive surveillance databases identified very small numbers of cases of yellow fever vaccine-associated viscerotropic disease, yellow fever vaccine-associated neurotropic disease, and anaphylaxis in persons ≥ 60 years. No other serious adverse events were identified in the other studies of vulnerable groups.
Patients use an internet technology to report when things go wrong.

As patients directly experience harm from adverse events, investigators have proposed patient-report to complement professional reporting of adverse events. To investigate how an automated health assessment system can be used to identify adverse events. Internet survey responses from April 2003 to April 2005 involving communities and clinical practices across the USA. 44,860 adults aged 19-69 years. Patient perceptions of adverse events experienced during the previous year. Independent legal review was also used to estimate how many patient-reports were serious enough to be potentially compensable. Although patient reports of possible adverse events was low (1.4%), the percentage of adverse events was eight times higher for patients with the greatest burden of illness than for those with the least (3.4% vs 0.4%). Two expert malpractice attorneys agreed that 9% of the adverse events seemed to be serious. PATIENTS will use internet technology to report their perceptions of health-related adverse events. Some of the patient-reported events reported will be serious.

Tofacitinib, an oral Janus kinase inhibitor approved for the treatment of rheumatoid arthritis (RA), provides patients with an alternative to subcutaneously or intravenously administered biologic disease-modifying antirheumatic drugs (DMARDs). Little is known about patient preference for novel RA treatments. To investigate patient preferences for attributes associated with RA treatments. A choice-based conjoint survey was mailed to 1400 randomly selected commercially insured patients (aged 21-80 years) diagnosed with RA, who were continuously enrolled from May 1, 2012, through April 30, 2013, and had ≥2 medical claims for International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code 714.0 and no previous biologic DMARD use. Treatment attributes included route of administration; monthly out-of-pocket cost; frequency of administration; ability to reduce daily joint pain and swelling; likelihood of serious adverse events; improvement in the ability to perform daily tasks; and medication burden. Mean attribute importance scores were calculated after adjusting for patient demographics (eg, age, sex, years since diagnosis) using a hierarchical Bayes model. Patient preferences for each treatment attribute were ranked by the importance score. Part-worth utilities (ie, preference scores) were used to perform a conjoint market simulation. A total of 380 patients (response rate, 27.1%) returned the survey. Their mean age (± standard deviation) was 54.9 (± 9.3) years. Nonrespondents were 2 years younger (mean, 52.9 years; P = .002) but did not differ significantly from respondents in known clinical characteristics. After adjustment for demographic characteristics, mean patients' ranking of treatment attribute importance, in decreasing order, was route of administration, 34.1 (± 15.5); frequency of administration, 16.4 (± 6.8); serious adverse events, 12.0 (± 9.3); cost, 10.1 (± 6.2); medication burden, 9.8 (± 8.2); joint pain reduction, 8.9 (± 3.8); and daily tasks improvement, 8.8 (± 4.7). For the route of administration attribute, the part-worth utility was highest for the oral route. Conjoint simulation results showed that 56.4% of respondents would prefer an oral route of administration. Based on this survey completed by 380 patients with RA, commercially insured patients with RA consider the route of administration to be the most important attribute of their RA treatment. In this study, the majority (56.4%) of patients preferred the oral route of administration over other routes. Understanding patient preferences may help to inform provider and payer decisions in treatment selection that may enhance patient adherence to therapy.
Adverse childhood events, substance abuse, and measures of affiliation.
Zlotnick, Cheryl; Tam, Tammy; Robertson, Marjorie J
2004-08-01
Adverse childhood events may influence later behaviors, including adulthood substance use and social affiliation. Studies have noted high prevalence rates of adverse childhood experiences and adulthood substance abuse among homeless adults. Using an existing longitudinal, countywide probability sample of 397 homeless adults, we examine the relationships among adverse childhood events on adulthood substance use, and the relationship of these variables to affiliation. Almost 75% of the sample had experienced an adverse childhood event. Path analysis indicated adulthood substance abuse mediated the inverse relationship between adverse childhood events and two measures of adulthood affiliation. Thus, although there is a relationship between adverse childhood events and adulthood substance use, it is adulthood substance use that determines most aspects of affiliation.

The transition between acute care and community care represents a vulnerable period in health care delivery. The vulnerability of this period has been attributed to changes to patients' medication regimens during hospitalization, failure to reconcile discrepancies between admission and discharge and the burdening of patients/families to take over care responsibilities at discharge and to relay important information to the primary care physician. Electronic communication platforms can provide an immediate link between acute care and community care physicians (and other community providers), designed to ensure consistent information transfer. This study examines whether a transfer-of-care (TOC) communication tool is efficacious and cost-effective for reducing hospital readmission, adverse events and adverse drug events as well as reducing death. A randomized controlled trial conducted on the Medical Teaching Unit of a Canadian tertiary care centre will evaluate the efficacy and cost-effectiveness of a TOC communication tool. Medical in-patients admitted to the unit will be considered for this study. Data will be collected upon admission, and a total of 1400 patients will be randomized. The control group's acute care stay will be summarized using a traditional dictated summary, while the intervention group will have a summary generated using the TOC communication tool. The primary outcome will be a composite, at 3 months, of death or readmission to any Alberta acute-care hospital. Secondary outcomes will be the occurrence of post-discharge adverse events and adverse drug events at 1 month post discharge. Patients with adverse outcomes will have their cases reviewed by two Royal College certified internists or College-certified family physicians, blinded to patients' group assignments, to determine the type, severity, preventability and ameliorability of all detected adverse outcomes. An accompanying economic evaluation will assess the cost per life saved, cost per readmission avoided and cost per QALY gained with the TOC communication tool compared to traditional dictation summaries. This paper outlines the study protocol for a randomized controlled trial evaluating an electronic transfer-of-care communication tool, with sufficient statistical power to assess the impact of the tool on the significant outcomes of post-discharge death or readmission. The study findings will inform health systems around the world on the potential benefits of such tools, and the value for money associated with their widespread implementation.

To evaluate the frequency, type, and predictors of intraoperative adverse events during donor hepatectomy for living-donor liver transplant. Retrospective analyses of the data from 182 consecutive living-donor liver transplant donors between May 2002 and September 2008. Ninety-one patients (50%) had at least 1 intraoperative adverse event including hypothermia (39%), hypotension (26%), need for transfusions (17%), and hypertension (7%). Patients with an adverse event were older (P = .001), had a larger graft weight (P = .023), more frequently underwent a right hepatectomy (P = .019), and were more frequently classified as American Society of Anesthesiologists physical status class II (P = .027) than those who did not have these adverse events. Logistic regression analysis revealed that only age (95% confidence interval 1.018-1.099; P = .001) was a risk factor for intraoperative adverse events. Patients with these adverse events more frequently required admission to the intensive care unit and were hospitalized longer postoperatively. A before and after analysis showed that after introduction of in-line fluid warmers and more frequent use of acute normovolemic hemodilution, the frequency of intraoperative adverse events was significantly lower (80% vs 29%; P < .001). Intraoperative adverse events such as hypothermia and hypotension were common in living-donor liver transplant donors, and older age was associated with an increased risk of these adverse events. However, the effect of these adverse events on postoperative recovery is not clear.

Little is known about how adverse events are summarised and reported in trials, as detailed information is usually considered confidential. We have acquired clinical study reports (CSRs) from the European Medicines Agency through the Freedom of Information Act. The CSRs describe the results of studies conducted as part of the application for marketing authorisation for the slimming pill orlistat. The purpose of this study was to study how adverse events were summarised and reported in study protocols, CSRs, and published papers of orlistat trials. We received the CSRs from seven randomised placebo controlled orlistat trials (4,225 participants) submitted by Roche. The CSRs consisted of 8,716 pages and included protocols. Two researchers independently extracted data on adverse events from protocols and CSRs. Corresponding published papers were identified on PubMed and adverse event data were extracted from this source as well. All three sources were compared. Individual adverse events from one trial were summed and compared to the totals in the summary report. None of the protocols or CSRs contained instructions for investigators on how to question participants about adverse events. In CSRs, gastrointestinal adverse events were only coded if the participant reported that they were "bothersome," a condition that was not specified in the protocol for two of the trials. Serious adverse events were assessed for relationship to the drug by the sponsor, and all adverse events were coded by the sponsor using a glossary that could be updated by the sponsor. The criteria for withdrawal due to adverse events were in one case related to efficacy (high fasting glucose led to withdrawal), which meant that one trial had more withdrawals due to adverse events in the placebo group. Finally, only between 3% and 33% of the total number of investigator-reported adverse events from the trials were reported in the publications because of post hoc filters, though six of seven papers stated that "all adverse events were recorded." For one trial, we identified an additional 1,318 adverse events that were not listed or mentioned in the CSR itself but could be identified through manually counting individual adverse events reported in an appendix. We discovered that the majority of patients had multiple episodes of the same adverse event that were only counted once, though this was not described in the CSRs. We also discovered that participants treated with orlistat experienced twice as many days with adverse events as participants treated with placebo (22.7 d versus 14.9 d, p-value < 0.0001, Student's t test). Furthermore, compared with the placebo group, adverse events in the orlistat group were more severe. None of this was stated in the CSR or in the published paper. Our analysis was restricted to one drug tested in the mid-1990s; our results might therefore not be applicable for newer drugs. In the orlistat trials, we identified important disparities in the reporting of adverse events between protocols, clinical study reports, and published papers. Reports of these trials seemed to have systematically understated adverse events. Based on these findings, systematic reviews of drugs might be improved by including protocols and CSRs in addition to published articles.

To estimate the incidence of adverse events in medical and surgical activity in public and private hospitals, and to assess the clinical situation of patients and the active errors. Prospective assessment of adverse events by external senior nursing and doctor investigators with ward staff. Random three-stage stratified cluster sampling of stays or fractions of stay in a 7-day observation period for each ward. 8754 patients observed in 292 wards in 71 hospitals, over 35,234 hospitalisation days. Number of adverse events in relation to number of days of hospitalisation. The incidence density of adverse events was 6.6 per 1000 days of hospitalisation (95% CI 5.7 to 7.5), of which 35% were preventable. Invasive procedures were the source of half the adverse events, of which 20% were preventable. Adverse events related to the psychological sphere and pain were mostly considered as preventable. Ward staff found it difficult to assess the role of care management in the occurrence of adverse events: 41% of adverse events were expected because of the disease itself, and could have occurred in the absence of the related medical management. At the national level in France, every year 120,000-190,000 adverse events during hospitalisation can be considered as preventable. Areas such as perioperative period and geriatric units should receive closer attention. As adverse events occurred more commonly in vulnerable patients, who are not specifically targeted by clinical guidance, practising evidence-based medicine is not likely to prevent all cases. Therefore clinical risk management should prioritize empowerment of local staff, provision of favourable conditions within the organisation, and staff training based on simple tools appropriate for ward-level identification and analysis of adverse events.

Malnutrition in gastrectomized patients receiving chemotherapy is associated with the susceptibility to chemotherapy-related adverse events. This study evaluated pre-operative nutritional status-related indices associated with adverse events in post-operation gastric cancer patients receiving chemotherapy. Medical records of 234 gastrectomized patients under adjuvant tegafur/gimeracil/oteracil chemotherapy with extended lymph node dissection were analyzed. Nutritional status assessment included Patient-Generated Subjective Global Assessment (PG-SGA), body weight, body mass index, serum albumin concentration, and Nutrition Risk Index (NRI). Chemotherapy-originated adverse events were determined using Common Terminology Criteria for Adverse Events. PG-SGA indicated 59% of the patients were malnourished, and 27.8% of the patients revealed serious malnutrition with PG-SGA score of ≥9. Fifteen % of patients lost ≥10% of the initial body weight, 14.5% of the patients had hypoalbuminemia (<3.5 g/dL), and 66.2% had NRI score less than 97.5 indicating moderate to severe malnutrition. Hematological adverse events were present in 94% (≥grade 1) and 16.2% (≥grade 3). Non-hematological adverse events occurred in 95.7% (≥grade1) and 16.7% (≥grade 3) of the patients. PG-SGA and NRI score was not associated with treatment-induced adverse events. Multivariate analyses indicated that female, low body mass index, and hypoalbuminemia were independent risk factors for grade 3/4 hematological adverse events. Age was an independent risk factor for grade 3/4 non-hematological adverse events. Neutropenia was the most frequently occurring adverse event, and associated risk factors were female, total gastrectomy, and hypoalbuminemia. Hypoalbuminemia, not PG-SGA or NRI may predict chemotherapy-induced adverse events in gastrectomized cancer patients.

To learn whether the risk of revaccination in adults should limit its use, the authors investigated whether adverse events requiring hospitalization occurred in a group of Medicare enrollees revaccinated with pneumococcal polysaccharide vaccine. A prospective cohort analysis and case study of revaccinated people involved five percent of all elderly Medicare enrollees from 1985 through 1988, consisting of 66,256 people receiving one dose of vaccine and 1,099 receiving two doses. Comparison was made of the hospitalization rate within 30 days after revaccination and rates of singly vaccinated persons using discharge diagnosis for all those hospitalized during the 30 days after revaccination. No significant difference was found between the hospitalization rate of the revaccinated cohort and comparison group. No adverse reactions attributable to pneumococcal polysaccharide vaccine causing hospitalization were identified among 39 revaccinated persons who were hospitalized within 30 days of revaccination. Revaccination of elderly Medicare beneficiaries does not cause events serious enough to require hospitalization. Vaccination of persons according to the Public Health Service Immunization Practice Advisory Committee guidelines is recommended when the prior immunization status is unknown.
The Value of Survival Gains in Pancreatic Cancer from Novel Treatment Regimens.
MacEwan, Joanna P; Yin, Wes; Kaura, Satyin; Khan, Zeba M

Metastatic pancreatic cancer (mPC) is associated with low survival, with less than 10% of patients surviving 5 years. Recent therapies improve survival outcomes where few alternative therapies exist, but few economic analyses measure the value of survival gains attributable to new therapies. To estimate the value of survival gains in advanced or mPC attributable to the introduction of novel treatment regimens. Multivariate Cox proportional hazards models were used to estimate real-world survival gains associated with the introduction of gemcitabine (GEM) for patients diagnosed with stage IV or unstaged mPC in the Surveillance, Epidemiology, and End Results Program cancer registries. Then, evidence from clinical trials was used to evaluate the survival gains associated with nab-paclitaxel + gemcitabine (nP +GEM) and FOLFIRINOX (FFX) relative to GEM. The survival estimates and clinical trial evidence were used to calibrate an economic model and assess the cumulative value of survival gains in mPC to patients. Costs of treatment were calculated based on published cost-effectiveness studies. We estimated that the introduction of GEM in 1996 was associated with a hazard ratio of 0.920 (P < 0.05) and an increase in median survival from 3.1 to 4.5 months. Results suggested that the value of survival gains attributable to GEM equaled about $71,000 per patient, while the value attributable to nP + GEM was an additional $56,700. Estimates for the value of survival gains per patient, net of total incremental lifetime treatment costs (drugs, adverse events, and other costs), were $50,294 for GEM and an additional $31,900 for nP + GEM. Clinical trials and cost-effectiveness studies reported an overall survival gain from FFX that was larger than, but statistically similar to, nP + GEM and had greater risk of adverse events and total incremental costs. We estimated that the total value of survival gains to mPC patients, net of total costs, associated with GEM was up to $47.6 billion, and the additional values attributable to nP+GEM and FFX were up to $39.0 billion and $26.3 billion, respectively. Historically, mPC patients have faced high disease burden and had few treatment options. Treatments introduced since 1996 have led to improved survival, with varying costs associated with treatment and adverse events. Accounting for total incremental costs, the majority of the value of survival gains from GEM and nP+GEM was retained by mPC patients, highlighting the value of innovation in settings where survival is low and few alternative therapies exist.

Safety of Medical Abortion Provided Through Telemedicine Compared With In Person.
Grossman, Daniel; Grindlay, Kate
2017-10-01
To compare the proportion of medical abortions with a clinically significant adverse event among telemedicine and in-person patients at a clinic system in Iowa during the first 7 years of the service. We conducted a retrospective cohort study. We analyzed data on clinically significant adverse events (hospital admission, surgery, blood transfusion, emergency department treatment, and death) for all medical abortions performed by telemedicine or in person at a clinic system in Iowa between July 1, 2008, and June 30, 2015. Data on adverse events came from required reporting forms submitted to the mifepristone distributor. We calculated the prevalence of adverse events and 95% CIs comparing telemedicine with in-person patients. The analysis was designed as a noninferiority study. Assuming the prevalence of adverse events to be 0.3%, telemedicine provision was considered to be inferior to in-person provision if the prevalence were 0.6% or higher. The required sample size was 6,984 in each group (one-sided α=0.025, power 90%). To explore whether patients with adverse events presented to emergency departments and were not reported, we conducted a survey of the 119 emergency departments in Iowa, asking whether they had treated a woman with an adverse event in the prior year. During the study period, 8,765 telemedicine and 10,405 in-person medical abortions were performed. Forty-nine clinically significant adverse events were reported (no deaths or surgery; 0.18% of telemedicine patients with any adverse event [95% CI 0.11-0.29%] and 0.32% of in-person patients [95% CI 0.23-0.45%]). The difference in adverse event prevalence was 0.13% (95% CI -0.01% to 0.28%, P=.07). Forty-two emergency departments responded to the survey (35% response rate); none reported treating a woman with an adverse event after medical abortion. Adverse events are rare with medical abortion, and telemedicine provision is noninferior to in-person provision with regard to clinically significant adverse events.

This article describes the methods and results of a project in the Copenhagen Hospital Corporation (H:S) on preventing adverse events. The aim of the project was to raise awareness about patients' safety, test a reporting system for adverse events, develop and test methods of analysis of events and propagate ideas about how to prevent adverse events. H:S developed an action plan and a reporting system for adverse events, founded an organization and developed an educational program on theories and methods of learning from adverse events for both leaders and employees. During the three-year period from 1 January 2002 to 31 December 2004, the H:S staff reported 6011 adverse events. In the same period, the organization completed 92 root cause analyses. More than half of these dealt with events that had been optional to report, the other half events that had been mandatory to report. The number of reports and the front-line staff's attitude towards reporting shows that the H:S succeeded in founding a safety culture. Future work should be centred on developing and testing methods that will prevent adverse events from happening. The objective is to suggest and complete preventive initiatives which will help increase patient safety.

Certain dietary supplements (DSs) used by military populations pose a threat to overall readiness. This study assessed members of the American Medical Society for Sports Medicine (AMSSM) regarding their knowledge of DS use among their patients and reporting of suspected adverse events. A thirteen-question retrospective, cross-sectional, Web-based survey sought data on practices regarding DSs and adverse event reporting. Anonymous Web-based survey. Military and civilian sports medicine physicians. The primary finding of the study was how frequently practitioners report adverse events associated with DS use. A total of 311 physicians responded to the survey. Only 51% of respondents had a reliable source for information on DS safety and 58% routinely discussed DS use with their patients. Although a majority (71%) of respondents had encountered adverse events associated with DS use, few of those (10%) confirmed reporting such events. Reasons that physicians did not report adverse events were lack of knowledge regarding where to report (68%), how to report (61%), and availability of time (9%). Our results indicate that some AMSSM physicians are familiar with DSs and have encountered adverse events associated with their use. However, reporting of these adverse events to the appropriate agency is minimal at best. The significant gaps in physician knowledge regarding how and where to report such events indicate a need to educate physicians on this subject. The findings of this survey indicate the need for provider education on reporting adverse events associated with DS use. Although reporting of adverse events is essential for removing harmful DSs from the market, a majority of physicians have limited knowledge on this issue. Moreover, the survey provides insight into the barriers to physician reporting of adverse events.

This is an update of a Cochrane overview published in Issue 9, 2011; that overview considered both efficacy and adverse events. This overview considers adverse events, with efficacy dealt with in a separate overview.Thirty-nine Cochrane reviews of randomised trials have examined the adverse events associated with individual drug interventions in acute postoperative pain. This overview brings together the results of those individual reviews. To provide an overview of adverse event rates associated with single-dose oral analgesics, compared with placebo, for acute postoperative pain in adults. We identified systematic reviews in The Cochrane Database of Systematic Reviews on The Cochrane Library through a simple search strategy. All reviews were overseen by a single review group. We extracted information related to participants experiencing any adverse event, and reports of serious adverse events, and deaths from the individual reviews. Information was available from 39 Cochrane reviews for 41 different analgesics or analgesic combinations (51 drug/dose/formulations) tested in single oral doses in participants with moderate or severe postoperative pain. This involved around 350 unique studies involving about 35,000 participants. Most studies involved younger participants with pain following removal of molar teeth.For most nonsteroidal anti-inflammatory drugs (NSAIDs), paracetamol, and combinations not containing opioids, there were few examples where participants experienced significantly more or fewer adverse events than with placebo. For aspirin 1000 mg and diflunisal 1000 mg, opioids, or fixed-dose combination drugs containing opioids, participants typically experienced significantly more adverse events than with placebo. Studies of combinations of ibuprofen and paracetamol reported significantly fewer adverse events.Serious adverse events were rare, occurring a rate of about 1 in 3200 participants.Most reviews did not report specific adverse events. Despite ongoing problems with the measurement, recording, and reporting of adverse events in clinical trials and in systematic reviews, the large amount of information available for single oral doses of analgesics provides evidence that adverse events rates are generally similar with active drug and placebo in these circumstances, except at higher doses of some drugs, and in combinations including opioids.

To assess the effects of coding and coding conventions on summaries and tabulations of adverse events data on suicidality within clinical study reports. Systematic electronic search for adverse events of suicidality in tables, narratives, and listings of adverse events in individual patients within clinical study reports. Where possible, for each event we extracted the original term reported by the investigator, the term as coded by the medical coding dictionary, medical coding dictionary used, and the patient's trial identification number. Using the patient's trial identification number, we attempted to reconcile data on the same event between the different formats for presenting data on adverse events within the clinical study report. 9 randomised placebo controlled trials of duloxetine for major depressive disorder submitted to the European Medicines Agency for marketing approval. Clinical study reports obtained from the EMA in 2011. Six trials used the medical coding dictionary COSTART (Coding Symbols for a Thesaurus of Adverse Reaction Terms) and three used MedDRA (Medical Dictionary for Regulatory Activities). Suicides were clearly identifiable in all formats of adverse event data in clinical study reports. Suicide attempts presented in tables included both definitive and provisional diagnoses. Suicidal ideation and preparatory behaviour were obscured in some tables owing to the lack of specificity of the medical coding dictionary, especially COSTART. Furthermore, we found one event of suicidal ideation described in narrative text that was absent from tables and adverse event listings of individual patients. The reason for this is unclear, but may be due to the coding conventions used. Data on adverse events in tables in clinical study reports may not accurately represent the underlying patient data because of the medical dictionaries and coding conventions used. In clinical study reports, the listings of adverse events for individual patients and narratives of adverse events can provide additional information, including original investigator reported adverse event terms, which can enable a more accurate estimate of harms. © Maund et al 2014.

Background As patients directly experience harm from adverse events, investigators have proposed patient‐report to complement professional reporting of adverse events. Objective To investigate how an automated health assessment system can be used to identify adverse events. Design and setting Internet survey responses from April 2003 to April 2005 involving communities and clinical practices across the USA. Patients 44 860 adults aged 19–69 years. Outcome Patient perceptions of adverse events experienced during the previous year. Independent legal review was also used to estimate how many patient‐reports were serious enough to be potentially compensable. Results Although patient reports of possible adverse events was low (1.4%), the percentage of adverse events was eight times higher for patients with the greatest burden of illness than for those with the least (3.4% vs 0.4%). Two expert malpractice attorneys agreed that 9% of the adverse events seemed to be serious. Conclusions Patients will use internet technology to report their perceptions of health‐related adverse events. Some of the patient‐reported events reported will be serious. PMID:17545349

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.

Literature Review of Associations among Attributes of Reported Drinking Water Disease Outbreaks
Ligon, Grant; Bartram, Jamie

Waterborne disease outbreaks attributed to various pathogens and drinking water system characteristics have adversely affected public health worldwide throughout recorded history. Data from drinking water disease outbreak (DWDO) reports of widely varying breadth and depth were synthesized to investigate associations between outbreak attributes and human health impacts. Among 1519 outbreaks described in 475 sources identified during review of the primarily peer-reviewed, English language literature, most occurred in the U.S., the U.K. and Canada (in descending order). The outbreaks are most frequently associated with pathogens of unknown etiology, groundwater and untreated systems, and catchment realm-associated deficiencies (i.e., contamination events). Relative frequencies of outbreaks by various attributes are comparable with those within other DWDO reviews, with water system size and treatment type likely driving most of the (often statistically-significant at p < 0.05) differences in outbreak frequency, case count and attack rate. Temporal analysis suggests that while implementation of surface (drinking) water management policies is associated with decreased disease burden, further strengthening of related policies is needed to address the remaining burden attributed to catchment and distribution realm-associated deficiencies and to groundwater viral and disinfection-only system outbreaks.

Patient safety is a priority issue in health systems, due to the damage costs, institutional weakening, lack of credibility, and frustration on those who committed an error that resulted in an adverse event. There is no standardized instrument for recording, reporting, and analyzing sentinel or adverse events (AE) in primary care. Our aim was to design and validate a surveillance system for recording sentinel events, adverse events and near miss incidents in primary care. We made a review of systems for recording and reporting adverse events in primary care. Then, we proposed an instrument to record these events, and register faults in the structure and process, in primary health care units in the Instituto Mexicano del Seguro Social. We showed VENCER-MF format to 35 subjects. Out of them, 100% identified a failure in care process, 90% recorded a sentinel event, 85% identified the cause of this event, 75% of them suggested some measures for avoiding the recurrence of adverse events. We used a Cronbach's alpha of 0.6, p=0.03. The instrument VENCER-MF has a good consistency for the identification of adverse events.

The implications of partial and no recovery from delirium after hospital discharge are not clear. We sought to explore whether partial and no recovery from delirium among recently discharged patients predicted increased adverse events (emergency room visits, hospitalisations, death) during the subsequent 3 months. Prospective study of recovery from delirium in older hospital inpatients. The Confusion Assessment Method was used to diagnose delirium in hospital and determine recovery status after discharge (T0). Adverse events were determined during the 3 months T0. Survival analysis to the first adverse event and counting process modelling for one or more adverse events were used to examine associations between recovery status (ordinal variable, 0, 1 or 2 for full, partial or no recovery, respectively) and adverse events. Of 278 hospital inpatients with delirium, 172 were discharged before the assessment of recovery status (T0). Delirium recovery status at T0 was determined for 152: 25 had full recovery, 32 had partial recovery and 95 had no recovery. Forty-four patients had at least one adverse event during the subsequent 3 months. In multivariable analysis of one or more adverse events, poorer recovery status predicted increased adverse events; the hazard ratio (HR) (95% confidence interval, CI) was 1.72 (1.09, 2.71). The association of recovery status with adverse events was stronger among patients without dementia. Partial and no recovery from delirium after hospital discharge appear to predict increased adverse events during the subsequent 3 months These findings have potentially important implications for in-hospital and post-discharge management and policy.

Crotalidae Polyvalent Immune Fab (Fab Antivenom) is the primary Viperid antivenom used in the United States since 2000. Adverse event data associated with its use are limited. The purpose of this study is to describe the prevalence of acute adverse events associated with the use of Fab antivenom. The American College of Medical Toxicology's Toxicology Investigators Consortium maintains a prospective case registry of poisoned and envenomated patients managed by medical toxicologists at the bedside. This registry includes the North American Snakebite sub-registry. We performed a review of 438 cases entered into the Snakebite sub-registry. A total of 373 (85.2%) received at least one vial of Fab Antivenom. Forty percent were children. Adverse events occurred in 10 patients (2.7%) of whom six were adults. Rash was the most common adverse event. More severe adverse events (hypotension, bronchospasm, and/or angioedema) occurred in four (1.1%) patients. Prophylaxis was administered prior to Fab antivenom in 4.0%. Eight patients received various treatments for their adverse events. Neither the initial number of Fab antivenom vials, atopic history, nor prior envenomation correlated with the prevalence of adverse events. This prevalence of adverse events was lower than in previous studies and in a meta-analysis of 11 studies. The types of adverse events and treatments used are consistent with those in previous reports. There were no prior reports of prophylaxis use with which to compare. The prevalence of Fab antivenom adverse events in the North American Snakebite Registry was 2.7%.
Impact of High-Reliability Education on Adverse Event Reporting by Registered Nurses.
McFarland, Diane M; Doucette, Jeffrey N
Adverse event reporting is one strategy to identify risks and improve patient safety, but, historically, adverse events are underreported by registered nurses (RNs) because of fear of retribution and blame. A program was provided on high reliability to examine whether education would impact RNs' willingness to report adverse events. Although the findings were not statistically significant, they demonstrated a positive impact on adverse event reporting and support the need to create a culture of high reliability.

Inhibition of the epidermal growth factor receptor (EGFR) is an established treatment that extends patient survival across a variety of tumor types. EGFR inhibitors fall into two main categories: anti-EGFR monoclonal antibodies, such as cetuximab and panitumumab, and first-generation tyrosine kinase inhibitors, such as afatinib, gefitinib, and erlotinib. Skin reactions are the most common EGFR inhibitor-attributable adverse event, resulting in papulopustular (acneiform) eruptions that can be painful and debilitating, and which may potentially have a negative impact on patients’ quality of life and social functioning, as well as a negative impact on treatment duration. Shortened treatment duration can, in turn, compromise antineoplastic efficacy. Similarly, appropriate management of skin reactions is dependent on their accurate grading; however, conventional means for grading skin reactions are inadequate, particularly within the context of clinical trials. Treating a skin reaction only once it occurs (reactive treatment strategies) may not be the most effective management approach; instead, prophylactic approaches may be preferable. Indeed, we support the viewpoint that prophylactic management of skin reactions should be recommended for all patients treated with EGFR inhibitors. Appropriate prophylactic management could effectively reduce the severity of skin reactions in patients treated with EGFR inhibitors and therefore has the potential to directly benefit patients and improve drug adherence. Accordingly, here we review published and still-emerging data, and provide practical and evidence-based recommendations and algorithms regarding the optimal prophylactic management of EGFR inhibitor-attributable skin reactions. Implications for Practice: Epidermal growth factor receptor (EGFR) inhibitors extend patient survival across a variety of tumor types. The most common EGFR inhibitor-attributable adverse events are skin reactions. Prophylactic—rather than reactive—management of skin reactions for all patients receiving EGFR inhibitors should be recommended because appropriate prophylaxis could effectively reduce the severity of skin reactions; thus, the derivation of highly effective prophylactic strategies has the potential to directly benefit patients. Accordingly, a review of the available data leads to practical and evidence-based recommendations and algorithms regarding the optimal prophylactic management of EGFR inhibitor-attributable skin reactions.

Optimizing outcomes with polymethylmethacrylate fillers.
Gold, Michael H; Sadick, Neil S
2018-06-01
The ideal filler should be long-lasting, biocompatible, chemically inert, soft and easy to use, and have a long history of safety. This review focuses on the evolution and development of the PMMA-collagen gel, Bellafill, and the 10 years of postmarketing experience of Bellafill since it received premarket approval (PMA) from the FDA as Artefill in 2006. Artefill was rebranded to Bellafill in 2015. The authors conducted a literature search on PubMed for key articles describing the steps in which Arteplast, a PMMA filler developed in 1989, led to the development of Bellafill, the only PMMA filler approved by the US FDA for the treatment of nasolabial folds and acne scar correction. The factors governing efficacy and safety were also evaluated for the major PMMA fillers available in the world. The process of manufacturing and purifying PMMA has played a major role in minimizing adverse events for Bellafill. Postmarketing surveillance data for the 2007-2016 period show that for more than 530 000 Bellafill syringes distributed worldwide, 11 confirmed granulomas (excluding clinical trial data) (0.002% of syringes sold) have been reported. Data on other PMMA fillers are limited and inconsistent. The authors suggest that adverse events are often attributable to lack of proficiency in treatment technique and other factors. Bellafill has demonstrated an excellent safety and effectiveness profile in multiple clinical studies, customer feedback, and 10 years of postmarketing surveillance experience. Adverse events occur with all fillers for a variety of reasons. In addition to quality of the product, injector skill and technique are critical to ensuring good clinical outcomes. © 2018 Wiley Periodicals, Inc.

Indications for endoscopic retrograde cholangiopancreatography (ERCP) have received little attention, especially in scientific or objective terms. To review the prevailing ERCP indications in the literature, and to propose and evaluate a new ERCP indication system, which relies on more objective pre-procedure parameters. An analysis was conducted on 1758 consecutive ERCP procedures, in which contemporaneous use was made of an a-priori indication system. Indications were based on the objective pre-procedure parameters and divided into primary [cholangitis, clinical evidence of biliary leak, acute (biliary) pancreatitis, abnormal intraoperative cholangiogram (IOC), or change/removal of stent for benign/malignant disease] and secondary [combination of two or three of: pain attributable to biliary disease ('P'), imaging evidence of biliary disease ('I'), and abnormal liver function tests (LFTs) ('L')]. A secondary indication was only used if a primary indication was not present. The relationship between this newly developed classification system and ERCP findings and adverse events was examined. The indications of cholangitis and positive IOC were predictive of choledocholithiasis at ERCP (101/154 and 74/141 procedures, respectively). With respect to secondary indications, only if all three of 'P', 'I', and 'L' were present there was a statistically significant association with choledocholithiasis (χ 2 (1) = 35.3, p < .001). Adverse events were associated with an unusual indication leading to greater risk of unplanned hospitalization (χ 2 (1) = 17.0, p < .001). An a-priori-based indication system for ERCP, which relies on pre-ERCP objective parameters, provides a more useful and scientific classification system than is available currently.

Hospital leaders lack tools to determine the financial impact of poor patient outcomes and adverse events. To provide health-care leaders with decision support for investments to improve care, we created a tool, the Healthcare Quality Calculator (HQCal), which uses institution-specific financial data to calculate impact of poor patient outcomes or quality improvement on present and future margin. Excel and Web-based versions of the HQCal were based on a cohort study framework and created with modular components including major drivers of cost and reimbursement. The Healthcare Quality Calculator (HQCal) compares payment, cost, and profit/loss for patients with and without poor outcomes or quality issues. Cost and payment information for groups with and without quality issues are used by the HQCal to calculate profit or loss. Importantly, institution-specific payment and cost data are used to calculate financial impact and attributable cost associated with poor patient outcomes, adverse events, or quality issues. Because future cost and reimbursement changes can be forecast, the HQCal incorporates a forward-looking component. The flexibility of the HQCal was demonstrated using surgical site infections after abdominal surgery and postoperative surgical airway complications. The Healthcare Quality Calculator determines financial impact of poor patient outcomes and the benefit of initiatives to improve quality. The calculator can identify quality issues that would provide the largest financial benefit if improved; however, it cannot identify specific interventions. The calculator provides a tool to improve transparency regarding both short- and long-term financial consequences of funding, or failing to fund, initiatives to close gaps in quality or improve patient outcomes.

With the development of Web 2.0 technology, social media websites have become lucrative but under-explored data sources for extracting adverse drug events (ADEs), which is a serious health problem. Besides ADE, other semantic relation types (e.g., drug indication and beneficial effect) could hold between the drug and adverse event mentions, making ADE relation extraction - distinguishing ADE relationship from other relation types - necessary. However, conducting ADE relation extraction in social media environment is not a trivial task because of the expertise-dependent, time-consuming and costly annotation process, and the feature space's high-dimensionality attributed to intrinsic characteristics of social media data. This study aims to develop a framework for ADE relation extraction using patient-generated content in social media with better performance than that delivered by previous efforts. To achieve the objective, a general semi-supervised ensemble learning framework, SSEL-ADE, was developed. The framework exploited various lexical, semantic, and syntactic features, and integrated ensemble learning and semi-supervised learning. A series of experiments were conducted to verify the effectiveness of the proposed framework. Empirical results demonstrate the effectiveness of each component of SSEL-ADE and reveal that our proposed framework outperforms most of existing ADE relation extraction methods The SSEL-ADE can facilitate enhanced ADE relation extraction performance, thereby providing more reliable support for pharmacovigilance. Moreover, the proposed semi-supervised ensemble methods have the potential of being applied to effectively deal with other social media-based problems. Copyright © 2017 Elsevier B.V.

A post-marketing surveillance study was conducted in Germany to assess the efficacy and tolerability of rofecoxib in the treatment of osteoarthritis (OA). Patients were eligible for inclusion in this study if they were being treated for the first time or being switched from other medications. More than three-quarters of the 80,371 patients enrolled in the study reported improved pain relief and function during treatment with rofecoxib (12.5 or 25 mg/day), including a reduction in pain experienced when walking on a flat surface or climbing or descending stairs. A majority of patients also considered that the duration of analgesia provided by rofecoxib was longer than with previous medications (predominantly non-steroidal anti-inflammatory drugs). Some 85% of patients reported an improvement in quality of life during rofecoxib therapy and a similar proportion considered once-daily rofecoxib to be a simpler regimen than their previous medications. Tolerability of rofecoxib was consistent with previous experience in controlled trials, with adverse events recorded in less than 1.5% of patients (n = 1090). No new or unexpected types of adverse events were recorded. A total of 81 serious adverse events were reported, corresponding to an event rate of approximately one per 1000 patient-years of treatment. Most of these serious events were not considered attributable to rofecoxib use. Physicians considered that rofecoxib provided better and more prolonged analgesia than previous medications and improved quality of life for more than 80% of patients, and regarded once-daily rofecoxib as a simpler treatment regimen than previous therapies in more than 90% of patients. Patient and physician satisfaction with rofecoxib was high in this survey. Most respondents regarded the drug as effective, easy to use, and a well-tolerated medication for the treatment of OA.

Introduction Patients triaged to tertiary care centers frequently undergo rotary-wing transport and may be exposed to additional risk for adverse events. The incidence of physiologic adverse events and their predisposing factors in mechanically ventilated patients undergoing aeromedical transport are unknown. Methods We performed a retrospective review of flight records of all interfacility, rotary-wing transports to a tertiary care, university hospital during 2001 to 2003. All patients receiving mechanical ventilation via endotracheal tube or tracheostomy were included; trauma, scene flights, and fixed transports were excluded. Data were abstracted from patient flight and hospital records. Adverse events were classified as either major (death, arrest, pneumothorax, or seizure) or minor (physiologic decompensation, new arrhythmia, or requirement for new sedation/paralysis). Bivariate associations between hospital and flight characteristics and the presence of adverse events were examined. Results Six hundred eighty-two interfacility flights occurred during the period of review, with 191 patients receiving mechanical ventilation. Fifty-eight different hospitals transferred patients, with diagnoses that were primarily cardiopulmonary (45%) and neurologic (37%). Median flight distance and time were 42 (31 to 83) km and 13 (8 to 22) minutes, respectively. No major adverse events occurred during flight. Forty patients (22%) experienced a minor physiologic adverse event. Vasopressor requirement prior to flight and flight distance were associated with the presence of adverse events in-flight (P < 0.05). Patient demographics, time of day, season, transferring hospital characteristics, and ventilator settings before and during flight were not associated with adverse events. Conclusion Major adverse events are rare during interfacility, rotary-wing transfer of critically ill, mechanically ventilated patients. Patients transferred over a longer distance or transferred on vasopressors may be at greater risk for minor adverse events during flight. PMID:18498659

Dexmedetomidine is an α(2)-adrenergic receptor agonist with sedative and analgesic effects in mechanically ventilated adults and children. Safety and efficacy data are limited in children. The purpose of this study is to retrospectively identify the incidence and types of adverse events noted in children receiving continuous infusions of dexmedetomidine and evaluate potential risk factors for adverse events. Between July 1, 2006, and July 31, 2007, data were collected on all children (< 18 years) who received continuous infusions of dexmedetomidine. Data collection included demographics, dexmedetomidine regimen, and type/number of adverse events. The primary endpoint was the total number of adverse events noted, including: transient hypertension, hypotension, neurological manifestations, apnea, and bradycardia. Secondary endpoints included categorization of each type of adverse event and an assessment of risk factors. A logistic regression model was used to assess the relationship of adverse events with independent variables including length of ICU stay, cumulative dose, peak infusion rate, duration of therapy, PRISM III score, and bolus dose. Thirty-six patients received dexmedetomidine representing 41 infusions. The median age was 16 months (range, 0.1-204 months) and median PRISM III score was 2 (range, 0-18). Eighteen (43.9%) patients received a bolus dose of dexmedetomidine. The median cumulative dose (mcg/kg) and peak dose (mcg/kg/hr) were 8.5 (range, 2.2-193.7) and 0.5 (range, 0.2-0.7), respectively. Dexmedetomidine was continued for a median of 20 (range, 3-263) hours. Six (14.6%) patients were slowly tapered off the continuous infusions. Twenty-one adverse events were noted in 17 patients, including 4 neurologic manifestations. Fourteen patients required interventions for adverse events. ICU length of stay was the only independent risk factor (p=0.036) for development of adverse events. Several potential adverse events were noted with dexmedetomidine continuous infusions including possible neurological manifestations. Further studies are needed looking at adverse events associated with dexmedetomidine use in the pediatric population.

Abstract Objective To evaluate rates of serious organ specific immune-related adverse events, general adverse events related to immune activation, and adverse events consistent with musculoskeletal problems for anti-programmed cell death 1 (PD-1) drugs overall and compared with control treatments. Design Systematic review and meta-analysis. Data sources Medline, Embase, Cochrane Library, Web of Science, and Scopus searched to 16 March 2017 and combined with data from ClinicalTrials.gov. Study selection Eligible studies included primary clinical trial data on patients with cancer with recurrent or metastatic disease. Data extraction Three independent investigators extracted data on adverse events from ClinicalTrials.gov and the published studies. Risk of bias was assessed using the Cochrane tool by three independent investigators. Results 13 relevant studies were included; adverse event data were available on ClinicalTrials.gov for eight. Studies compared nivolumab (n=6), pembrolizumab (5), or atezolizumab (2) with chemotherapy (11), targeted drugs (1), or both (1). Serious organ specific immune-related adverse events were rare, but compared with standard treatment, rates of hypothyroidism (odds ratio 7.56, 95% confidence interval 4.53 to 12.61), pneumonitis (5.37, 2.73 to 10.56), colitis (2.88, 1.30 to 6.37), and hypophysitis (3.38, 1.02 to 11.08) were increased with anti-PD-1 drugs. Of the general adverse events related to immune activation, only the rate of rash (2.34, 2.73 to 10.56) increased. Incidence of fatigue (32%) and diarrhea (19%) were high but similar to control. Reporting of adverse events consistent with musculoskeletal problems was inconsistent; rates varied but were over 20% in some studies for arthraligia and back pain. Conclusions Organ specific immune-related adverse events are uncommon with anti-PD-1 drugs but the risk is increased compared with control treatments. General adverse events related to immune activation are largely similar. Adverse events consistent with musculoskeletal problems are inconsistently reported but adverse events may be common.

Aim The aim of this review was to summarize the prevalence, frequency and comparative value of information on the adverse events of healthcare interventions from user comments and videos in social media. Methods A systematic review of assessments of the prevalence or type of information on adverse events in social media was undertaken. Sixteen databases and two internet search engines were searched in addition to handsearching, reference checking and contacting experts. The results were sifted independently by two researchers. Data extraction and quality assessment were carried out by one researcher and checked by a second. The quality assessment tool was devised in-house and a narrative synthesis of the results followed. Results From 3064 records, 51 studies met the inclusion criteria. The studies assessed over 174 social media sites with discussion forums (71%) being the most popular. The overall prevalence of adverse events reports in social media varied from 0.2% to 8% of posts. Twenty-nine studies compared the results from searching social media with using other data sources to identify adverse events. There was general agreement that a higher frequency of adverse events was found in social media and that this was particularly true for ‘symptom’ related and ‘mild’ adverse events. Those adverse events that were under-represented in social media were laboratory-based and serious adverse events. Conclusions Reports of adverse events are identifiable within social media. However, there is considerable heterogeneity in the frequency and type of events reported, and the reliability or validity of the data has not been thoroughly evaluated. PMID:26271492

The study examined the effectiveness of a perinatal collaborative care intervention in moderating the effects of adverse neonatal birth events on risks of postpartum depressive symptoms and impaired functioning among women of lower socioeconomic status with antenatal depression. A randomized controlled trial with blinded outcome assessments was conducted in ten public health centers, comparing MOMCare (choice of brief interpersonal psychotherapy, pharmacotherapy, or both) with intensive maternity support services (MSS-Plus). Participants had probable diagnoses of major depressive disorder or dysthymia during pregnancy. Generalized estimating equations estimated differences in depression and functioning measures between groups with and without adverse birth events within the treatment arms. A total of 160 women, 43% of whom experienced at least one adverse birth event, were included in the analyses. For women who received MOMCare, postpartum depression scores (measured with the Symptom Checklist-20) did not differ by whether or not they experienced an adverse birth event (mean±SD scores of .86±.51 for mothers with an adverse birth event and .83±.56 for mothers with no event; p=.78). For women who received MSS-Plus, having an adverse birth event was associated with persisting depression in the postpartum period (mean scores of 1.20±.0.61 for mothers with an adverse birth event and .93±.52 for mothers without adverse birth event; p=.04). Similar results were seen for depression response rates and functioning. MOMCare mitigated the risk of postpartum depressive symptoms and impaired functioning among women of low socioeconomic status who had antenatal depression and who experienced adverse birth events.

Background We performed a systematic review to assess whether we can quantify the underreporting of adverse events (AEs) in the published medical literature documenting the results of clinical trials as compared with other nonpublished sources, and whether we can measure the impact this underreporting has on systematic reviews of adverse events. Methods and Findings Studies were identified from 15 databases (including MEDLINE and Embase) and by handsearching, reference checking, internet searches, and contacting experts. The last database searches were conducted in July 2016. There were 28 methodological evaluations that met the inclusion criteria. Of these, 9 studies compared the proportion of trials reporting adverse events by publication status. The median percentage of published documents with adverse events information was 46% compared to 95% in the corresponding unpublished documents. There was a similar pattern with unmatched studies, for which 43% of published studies contained adverse events information compared to 83% of unpublished studies. A total of 11 studies compared the numbers of adverse events in matched published and unpublished documents. The percentage of adverse events that would have been missed had each analysis relied only on the published versions varied between 43% and 100%, with a median of 64%. Within these 11 studies, 24 comparisons of named adverse events such as death, suicide, or respiratory adverse events were undertaken. In 18 of the 24 comparisons, the number of named adverse events was higher in unpublished than published documents. Additionally, 2 other studies demonstrated that there are substantially more types of adverse events reported in matched unpublished than published documents. There were 20 meta-analyses that reported the odds ratios (ORs) and/or risk ratios (RRs) for adverse events with and without unpublished data. Inclusion of unpublished data increased the precision of the pooled estimates (narrower 95% confidence intervals) in 15 of the 20 pooled analyses, but did not markedly change the direction or statistical significance of the risk in most cases. The main limitations of this review are that the included case examples represent only a small number amongst thousands of meta-analyses of harms and that the included studies may suffer from publication bias, whereby substantial differences between published and unpublished data are more likely to be published. Conclusions There is strong evidence that much of the information on adverse events remains unpublished and that the number and range of adverse events is higher in unpublished than in published versions of the same study. The inclusion of unpublished data can also reduce the imprecision of pooled effect estimates during meta-analysis of adverse events. PMID:27649528

Molecular diagnostics are increasingly being used to help guide decision-making for personalized medical treatment of breast and colorectal cancer patients. The main aim of this study was to better understand and determine breast and colorectal cancer patients' decision-making strategies and the trade-offs they make in deciding about characteristics of molecular genomic diagnostics for breast and colorectal cancer. We surveyed a nationally representative sample of 300 breast and colorectal cancer patients using a previously developed web-administered instrument. Eligibility criteria included patients aged 18 years and older with either breast or colorectal cancer. We explored several attributes and attribute levels of molecular genomic diagnostics in 20 scenarios. Our analysis revealed that both breast and colorectal cancer patients weighted the capability of molecular genomic diagnostics to determine the probability of treatment efficacy as being of greater importance than information provided to detect adverse events. The probability of either false-positive or -negative results was ranked highly as a potential barrier by both breast and colorectal patients. However, 78.6% of breast cancer patients ranked the possibility of a 'false-negative test result leading to undertreatment' higher than the 'chance of a false positive, which may lead to overtreatment' (68%). This finding contrasted with the views of colorectal cancer patients who ranked the chance of a false positive as being of greater concern than a false negative (72.8 vs 63%). Overall, cancer patients exhibited a high willingness to accept and pay for genomic diagnostic tests, especially among breast cancer patients. Cancer patients seek a test accuracy rate of 90% or higher. Breast and colorectal cancer patients' decisions about genomic diagnostics are influenced more by the probability of being cured than by avoiding potential severe adverse events. This study provides insights into the relative weight that breast and colorectal cancer patients place on various aspects of molecular genomic diagnostics, and the trade-offs they are willing to make among attributes of such tests.

Objective To assess the effects of coding and coding conventions on summaries and tabulations of adverse events data on suicidality within clinical study reports. Design Systematic electronic search for adverse events of suicidality in tables, narratives, and listings of adverse events in individual patients within clinical study reports. Where possible, for each event we extracted the original term reported by the investigator, the term as coded by the medical coding dictionary, medical coding dictionary used, and the patient’s trial identification number. Using the patient’s trial identification number, we attempted to reconcile data on the same event between the different formats for presenting data on adverse events within the clinical study report. Setting 9 randomised placebo controlled trials of duloxetine for major depressive disorder submitted to the European Medicines Agency for marketing approval. Data sources Clinical study reports obtained from the EMA in 2011. Results Six trials used the medical coding dictionary COSTART (Coding Symbols for a Thesaurus of Adverse Reaction Terms) and three used MedDRA (Medical Dictionary for Regulatory Activities). Suicides were clearly identifiable in all formats of adverse event data in clinical study reports. Suicide attempts presented in tables included both definitive and provisional diagnoses. Suicidal ideation and preparatory behaviour were obscured in some tables owing to the lack of specificity of the medical coding dictionary, especially COSTART. Furthermore, we found one event of suicidal ideation described in narrative text that was absent from tables and adverse event listings of individual patients. The reason for this is unclear, but may be due to the coding conventions used. Conclusion Data on adverse events in tables in clinical study reports may not accurately represent the underlying patient data because of the medical dictionaries and coding conventions used. In clinical study reports, the listings of adverse events for individual patients and narratives of adverse events can provide additional information, including original investigator reported adverse event terms, which can enable a more accurate estimate of harms.

Hip fractures are one of the most common types of orthopaedic injury with high rates of morbidity. Currently, no study has compared risk factors and adverse events following the different types of hip fracture surgeries. The purpose of this paper is to investigate the major and minor adverse events and risk factors for complication development associated with five common surgeries for the treatment of hip fractures using the NSQIP database. Using the ACS-NSQIP database, complications for five forms of hip surgeries were selected and categorized into major and minor adverse events. Demographics and clinical variables were collected and an unadjusted bivariate logistic regression analyses was performed to determine significant risk factors for adverse events. Five multivariate regressions were run for each surgery as well as a combined regression analysis. A total of 9640 patients undergoing surgery for hip fracture were identified with an adverse events rate of 25.2% (n=2433). Open reduction and internal fixation of a femoral neck fracture had the greatest percentage of all major events (16.6%) and total adverse events (27.4%), whereas partial hip hemiarthroplasty had the greatest percentage of all minor events (11.6%). Mortality was the most common major adverse event (44.9-50.6%). For minor complications, urinary tract infections were the most common minor adverse event (52.7-62.6%). Significant risk factors for development of any adverse event included age, BMI, gender, race, active smoking status, history of COPD, history of CHF, ASA score, dyspnoea, and functional status, with various combinations of these factors significantly affecting complication development for the individual surgeries. Hip fractures are associated with significantly high numbers of adverse events. The type of surgery affects the type of complications developed and also has an effect on what risk factors significantly predict the development of a complication. Concerted efforts from orthopaedists should be made to identify higher risk patients and prevent the most common adverse events that occur postoperatively. Copyright © 2014 Elsevier Ltd.

Purpose: Although the likelihood of radiation-related adverse events influences treatment decisions regarding radiation therapy after prostatectomy for eligible patients, the data available to inform decisions are limited. This study was designed to evaluate the genitourinary, gastrointestinal, and sexual adverse events associated with postprostatectomy radiation therapy and to assess the influence of radiation timing on the risk of adverse events. Methods: The Regione Emilia-Romagna Italian Longitudinal Health Care Utilization Database was queried to identify a cohort of men who received radical prostatectomy for prostate cancer during 2003 to 2009, including patients who received postprostatectomy radiation therapy. Patients with prior radiation therapymore » were excluded. Outcome measures were genitourinary, gastrointestinal, and sexual adverse events after prostatectomy. Rates of adverse events were compared between the cohorts who did and did not receive postoperative radiation therapy. Multivariable Cox proportional hazards models were developed for each class of adverse events, including models with radiation therapy as a time-varying covariate. Results: A total of 9876 men were included in the analyses: 2176 (22%) who received radiation therapy and 7700 (78%) treated with prostatectomy alone. In multivariable Cox proportional hazards models, the additional exposure to radiation therapy after prostatectomy was associated with increased rates of gastrointestinal (rate ratio [RR] 1.81; 95% confidence interval [CI] 1.44-2.27; P<.001) and urinary nonincontinence events (RR 1.83; 95% CI 1.83-2.80; P<.001) but not urinary incontinence events or erectile dysfunction. The addition of the time from prostatectomy to radiation therapy interaction term was not significant for any of the adverse event outcomes (P>.1 for all outcomes). Conclusion: Radiation therapy after prostatectomy is associated with an increase in gastrointestinal and genitourinary adverse events. However, the timing of radiation therapy did not influence the risk of radiation therapy–associated adverse events in this cohort, which contradicts the commonly held clinical tenet that delaying radiation therapy reduces the risk of adverse events.« less

The Accreditation Council for Graduate Medical Education (ACGME) core competency of practice-based learning and improvement can be assessed with surgical Morbidity and Mortality Conference (MMC). We aim to describe the MMC reporting patterns of general surgery residents, describe the adverse event rate for patients and compare that with existing published rates, and describe the nature of our institutional adverse events. We hypothesize that reporting patterns and incidence rates will remain constant over time. In this retrospective cohort study, archived MMC case lists were evaluated from January 1, 2009 to December 31, 2010. The reporting patterns of the residents, the adverse event ratios, and the specific categories of adverse events were described over the academic years. χ(2) and Fisher's exact tests were used to compare across academic years, using an α = 0.05. There were 85 surgical MMC case lists evaluated. Services achieved a reporting rate above 80% (p < 0.001). The most consistent reporting was done by postgraduate year (PGY) 5 level chief residents for all services (p > 0.05). Out of 11,368 patients evaluated from complete MMC submissions, 289 patients had an adverse event reported (2.5%). This was lower than published reporting rates for patient adverse event rates (p < 0.001). Adverse event rates were consistent for residents at the postgraduate year 2, 4, and 5 levels for all services (p > 0.05). Over 2 years, 522 adverse events were reported for 461 patients. A majority of adverse events were from death (24.1%), hematologic and/or vascular events (16.7%), and gastrointestinal system events (16.1%). Surgery resident MMC reporting patterns and adverse event rates are generally stable over time. This study shows which adverse event cases are important for chief residents to report.

Insulin pumps (for continuous subcutaneous insulin infusion [CSII]) are used widely in type 1 diabetes mellitus. Although there has been considerable study of outcomes, there are few recent data on CSII-associated adverse events and no data on family perceptions of adverse events and their confidence in dealing with them. We approached all families of children and adolescents ≤ 19 years of age on CSII attending the diabetes clinic over a 16-week clinic cycle. Participants completed a retrospective questionnaire examining issues over the previous 12 months. Data on pump adverse events as well as answers to questions pertaining to education and confidence were collected. Our survey received a response rate of 99%, with 235 of the 238 families approached participating. In the preceding 12 months, 104 of 230 (45%) had reported at least one pump-related adverse event (either mechanical or set-related), with an associated 52 of 229 (23%) resulting in pump replacement. This equated to a minimum incidence density of 53 adverse events/100 person-years. Additionally, 18 of 230 (8%) reported a hospital admission or emergency department attendance as a consequence. Pump malfunction and infusion set/site failures were the most common events reported, with one or more events in 58 of 104 (56%) and 47 of 104 (45%), respectively. Adverse events, excluding set/site failures, were associated with older age (13.1 ± 3.4 years vs. 11.9 ± 4 years; P = 0.02). This is the first study to look at family perceptions of adverse events while using modern CSII. It highlights a high self-reported rate of CSII-related adverse events, pump replacement, and subsequent presentation to the hospital. Potential areas for additional targeted education are identified. Further prospective study examining pump adverse event characteristics and incidence is warranted.

OBJECTIVES: Patients with cancer who are treated with chemotherapy report adverse events during their treatment, which can affect their quality of life and increase the likelihood that their treatment will not be completed. In this study, patients' perceptions of the physician-patient relationship and communication about cancer-related issues, particularly adverse events were examined. METHODS: We surveyed 508 patients with cancer concerning the occurrence of adverse events and their relationship and communication with their physicians regarding cancer, treatment, and adverse events. RESULTS: Most individuals surveyed (>90%) discussed diagnosis, treatment plan, goals, and schedule, and potential adverse events with their physicians before initiating chemotherapy; approximately 75% of these individuals understood these topics completely or very well. Physician-patient discussions of adverse events were common, with tiredness, nausea and vomiting, and loss of appetite discussed prior to chemotherapy in over 80% of communications. These events were also the most often experienced (ranging in 95% to 64% of the respondents) along with low white blood cell counts (WBCs), which were experienced in 67% of respondents. Approximately 75% of the individuals reported that their overall quality of life was affected by adverse events. CONCLUSIONS: These findings suggest that discussions alone do not provide patients with sufficient understanding of the events, nor do they appear to adequately equip patients to cope with them. Therefore, efforts to improve cancer care should focus on developing tools to improve patients' understanding of the toxicities of chemotherapy, as well as providing resources to reduce the effects of adverse events.

The psychosocial processes implicated in the development and maintenance of psychosis differ according to both the dimensional attributes (conviction, frequency, associated distress, adverse life impact) and the content or type (e.g. grandiosity, hallucinations, paranoia) of the psychotic symptoms experienced. This has informed the development of 'targeted' cognitive behavioural therapy for psychosis (CBTp): interventions focusing on specific psychological processes in the context of particular symptom presentations. In adults, larger effect sizes for change in primary outcomes are typically reported in trials of targeted interventions, compared to those for trials of generic CBTp approaches with multiple therapeutic foci. We set out to test the theoretical basis for developing targeted CBTp interventions for young people with distressing psychotic-like, or unusual, experiences (UEs). We investigated variations in the psychosocial processes previously associated with self-reported UE severity (reasoning, negative life events, emotional problems) according to UE dimensional attributes and content/type (using an established five-factor model) in a clinically referred sample of 72 young people aged 8-14 years. Regression analyses revealed associations of conviction and grandiosity with reasoning; of frequency, and hallucinations and paranoia, with negative life events; and of distress/adverse life impact, and paranoia and hallucinations, with emotional problems. We conclude that psychological targets for intervention differ according to particular characteristics of childhood UEs in much the same way as for psychotic symptoms in adults. The development of targeted interventions is therefore indicated, and tailoring therapy according to presentation should further improve clinical outcomes for these young people.
Kiovig for primary immunodeficiency: reduced infusion and decreased costs per infusion.
Connolly, Mark; Simoens, Steven
2011-09-01
Kiovig is a ready-to-use 10% liquid immunoglobulin preparation that is medically indicated for the treatment of primary immunodeficiency. This study aims to conduct an economic evaluation which compares the intravenous immunoglobulin (IVIg) preparations Kiovig, Multigam, and Sandoglobulin from the Belgian societal perspective. As three prospective studies have observed no difference in outcomes, a cost-minimization analysis is considered appropriate to evaluate differences in treatment costs that can arise from IVIgs. A decision-analytic model simulated treatment costs attributed to one infusion. Resource use data were derived from a Dutch costing study. Cost items included immunoglobulin costs, pharmacy administration and nursing costs, mini-forfait for hospital infusion, costs of adverse events, and lost productivity with 2009 as base year. Cost data were identified from published sources and Belgian hospital administrators. A probabilistic sensitivity analysis explored the impact of parameter uncertainty on cost results. Costs per infusion cycle in adult primary immunodeficiency patients were €1,046 (95% confidence interval: €1,006-1,093) with Kiovig; €1,102 (€1,064-1,147) with Multigam; and €1,147 (€1,108-1,193) with Sandoglobulin. The average cost savings per infusion with Kiovig as compared to Multigam and Sandoglobulin amounted to €56 and €101 per infusion. In conclusion, treatment costs with Kiovig were shown to be lower as compared to other IVIgs in Belgium. Reduced costs per infusion were attributed to lower costs associated with treating adverse events and the opportunity cost of nursing time and time off work for working adults.

A crucial aspect of medical consumerism has been overlooked in past research and policymaking: how consumers decide whom to "blame" for bad outcomes. This study explores how, in a system increasingly dominated by managed care, these attributions affect consumers' attitudes and behavior. Using data from the experiences of people with serious mental illness, hypotheses are tested regarding the origins and consequences of blaming for medical consumerism. Blame was allocated to health plans in a manner similar, but not identical, to the way in which blame was allocated to health care professionals. Both allocations are shaped by enrollment in managed care, with blame allocation affecting consumers' subsequent willingness to talk about adverse events. Policy implications include the need for more finely tuned grievance procedures and better consumer education about managed care practices.

Adverse drug reactions and interactions are among the major causes of death in the United States. Antidepressants have been reported as causing suicide and homicide and share the class attribute of frequently producing akathisia, a state of severe restlessness associated with thoughts of death and violence. Medical examiners can now identify some pharmacogenetic interactions that cause drugs, deemed safe for most, to be lethal to others. Such deaths do not yet include medication-induced, akathisia-related suicides and homicides. An extrapyramidal side effect, akathisia is a manifestation of drug toxicity whose causes lie, inter alia, in drugs, doses, and co-prescribed medications that inhibit and compete for metabolizing enzymes, which may themselves be defective. In this paper, we report our investigation into adverse drug reactions/interactions in three persons who committed homicide, two also intending suicide, while on antidepressants prescribed for stressful life events. Their histories of medication use, adverse reactions and reasons for changes in medications are presented. DNA samples were screened for variants in the cytochrome P450 gene family; that produce drug metabolizing enzymes. All three cases exhibit genotype-based diminished metabolic capability that, in combination with their enzyme inhibiting/competing medications, decreased metabolism further and are the likely cause of these catastrophic events.

To calculate, for the first time, the direct and social costs of transfusion-related adverse events in order to include them in the National Healthcare System's budget, calculation and studies. In Spain more than 1,500 patients yearly are diagnosed with such adverse events. Blood transfusion-related adverse events recorded yearly in Spanish haemovigilance reports were studied retrospectively (2010-2015). The adverse events were coded according to the classification of Diagnosis-Related Groups. The direct healthcare costs were obtained from public information sources. The productivity loss (social cost) associated with adverse events was calculated using the human capital and hedonic salary methodologies. In 2015, 1,588 patients had adverse events that resulted in direct health care costs (4,568,914€) and social costs due to hospitalization (200,724€). Three adverse reactions resulted in patient death (at a social cost of 1,364,805€). In total, the cost of blood transfusion-related adverse events was 6,134,443€ in Spain. For the period 2010-2015: the trends show a reduction in the total amount of transfusions (2 vs. 1.91M€; -4.4%). The number of adverse events increased (822 vs. 1,588; +93%), as well as their related direct healthcare cost (3.22 vs. 4.57M€; +42%) and the social cost of hospitalization (110 vs 200M€; +83%). Mortality costs decreased (2.65 vs. 1.36M€; -48%). This is the first time that the costs of post-transfusion adverse events have been calculated in Spain. These new figures and trends should be taken into consideration in any cost-effectiveness study or trial of new surgical techniques or sanitary policies that influence blood transfusion activities.

Even though proton pump inhibitors (PPIs) are commonly used in clinical practice, a limited number of studies are available about cutaneous adverse reactions from PPIs, and most of these are case reports. To demonstrate the pattern of cutaneous reactions related to PPI usage and to evaluate the risk of developing PPI drug eruptions among adult patients. We reviewed the spontaneous reports of any adverse events associated with PPI use, as reported from January 2005 through May 2010 to the Adverse Drug Reaction Center at Siriraj Hospital in Thailand. Each control was sampled from 15 patients who had consecutive hospital numbers from each study case. The prevalence of cutaneous reactions to PPIs varied, ranging from three to 20 per 100,000 of the treated population. Sixty-four patients with a history of reaction to PPIs, and 65 controls were enrolled. Most cutaneous reactions were attributed to omeprazole (n=50; 78.1%), and the most frequently observed cutaneous reaction was maculopapular rash (43.8%). None of the patients experienced a cross-reaction between individual PPIs. Cutaneous adverse reactions to PPIs range from minor drug rashes to a severe, life-threatening reaction. Individuals with a history of adverse drug reaction have an increased risk of cutaneous reaction to PPIs.

To investigate the impact of increasing sample of records reviewed bi-weekly with the Global Trigger Tool method to identify adverse events in hospitalised patients. Retrospective observational study. A Norwegian 524-bed general hospital trust. 1920 medical records selected from 1 January to 31 December 2010. Rate, type and severity of adverse events identified in two different samples sizes of records selected as 10 and 70 records, bi-weekly. In the large sample, 1.45 (95% CI 1.07 to 1.97) times more adverse events per 1000 patient days (39.3 adverse events/1000 patient days) were identified than in the small sample (27.2 adverse events/1000 patient days). Hospital-acquired infections were the most common category of adverse events in both the samples, and the distributions of the other categories of adverse events did not differ significantly between the samples. The distribution of severity level of adverse events did not differ between the samples. The findings suggest that while the distribution of categories and severity are not dependent on the sample size, the rate of adverse events is. Further studies are needed to conclude if the optimal sample size may need to be adjusted based on the hospital size in order to detect a more accurate rate of adverse events.

There has been a theoretical debate as to which retrospective record review method is the most valid, reliable, cost efficient and feasible for detecting adverse events. The aim of the present study was to evaluate the feasibility and capability of two common retrospective record review methods, the "Harvard Medical Practice Study" method and the "Global Trigger Tool" in detecting adverse events in adult orthopaedic inpatients. We performed a three-stage structured retrospective record review process in a random sample of 350 orthopaedic admissions during 2009 at a Swedish university hospital. Two teams comprised each of a registered nurse and two physicians were assigned, one to each method. All records were primarily reviewed by registered nurses. Records containing a potential adverse event were forwarded to physicians for review in stage 2. Physicians made an independent review regarding, for example, healthcare causation, preventability and severity. In the third review stage all adverse events that were found with the two methods together were compared and all discrepancies after review stage 2 were analysed. Events that had not been identified by one of the methods in the first two review stages were reviewed by the respective physicians. Altogether, 160 different adverse events were identified in 105 (30.0%) of the 350 records with both methods combined. The "Harvard Medical Practice Study" method identified 155 of the 160 (96.9%, 95% CI: 92.9-99.0) adverse events in 104 (29.7%) records compared with 137 (85.6%, 95% CI: 79.2-90.7) adverse events in 98 (28.0%) records using the "Global Trigger Tool". Adverse events "causing harm without permanent disability" accounted for most of the observed difference. The overall positive predictive value for criteria and triggers using the "Harvard Medical Practice Study" method and the "Global Trigger Tool" was 40.3% and 30.4%, respectively. More adverse events were identified using the "Harvard Medical Practice Study" method than using the "Global Trigger Tool". Differences in review methodology, perception of less severe adverse events and context knowledge may explain the observed difference between two expert review teams in the detection of adverse events.

The present study aimed to objectively evaluate the adverse events after the administration of chemotherapeutic agents used in the University of Wisconsin (UW)-Madison chemotherapy protocol (UW-25) for canine lymphoma, using the Veterinary Co-operative Oncology Group common terminology criteria for adverse events (VCOG-CTCAE). The medical records of 40 dogs with multicentric high-grade lymphoma that underwent UW-25 were reviewed. Gastrointestinal adverse events of grade 2 and above and blood/bone marrow adverse events of all grades were evaluated. Gastrointestinal adverse events occurring at least once during the entire period of UW-25 were observed in 50% (20/40), 17.9% (7/39), and 8.1% (3/37) of the dogs after the administration of vincristine (VCR), cyclophosphamide (CPA), and doxorubicin (DXR), respectively. Blood/bone marrow adverse events occurring at least once during UW-25 were observed in 57.5% (23/40), 41% (16/39), and 8.1% (3/37) of the dogs after the administration of VCR, CPA, and DXR, respectively. The rate of patients that experienced gastrointestinal adverse events was higher after the first administration of VCR than after the first administration of DXR. Findings obtained in this study will be helpful in predicting the adverse events that could occur when dogs with lymphoma are treated with UW-25.

The aim of this study was to estimate the incidence of adverse events in acute surgical admissions for cardiac disease in admitted episodes in the year 2003-2004 and to estimate the cost of these complications to the Victorian health system. Cardiac surgery adverse events are among the most frequent and significant contributors to the morbidity, mortality and cost associated with hospitalisation. Patient-level costing data set for major Victorian public hospitals in 2003-2004 was analysed for adverse events using C-prefixed markers, denoting complications that arose during the course of hospital treatment for cardiac surgery diagnosis related groups (DRGs). The cost of adverse events was estimated by linear regression modelling, adjusted for age and co-morbidity. A total of 16,766 multi-day cardiac disease cases were identified, of whom 6,181 (36.85%) had at least one adverse event. Patients with adverse events stayed approximately 7 days longer and had four times the case fatality rate than those without. After adjustment for age and co-morbidity, the presence of an adverse event adds AUS$5,751. The sum of the total cost of adverse events for each DRG was AUS$42.855 million, representing 21.6% of total expenditure on cardiac surgery and adding 27.5% in broad terms to the cardiac surgery budget.
Summarizing the incidence of adverse events using volcano plots and time intervals.
Zink, Richard C; Wolfinger, Russell D; Mann, Geoffrey

Adverse event incidence analyses are a critical component for describing the safety profile of any new intervention. The results typically are presented in lengthy summary tables. For therapeutic areas where patients have frequent adverse events, analysis and interpretation are made more difficult by the sheer number and variety of events that occur. Understanding the risk in these instances becomes even more crucial. We describe a space-saving graphical summary that overcomes the limitations of traditional presentations of adverse events and improves interpretability of the safety profile. We present incidence analyses of adverse events graphically using volcano plots to highlight treatment differences. Data from a clinical trial of patients experiencing an aneurysmal subarachnoid hemorrhage are used for illustration. Adjustments for multiplicity are illustrated. Color is used to indicate the treatment with higher incidence; bubble size represents the total number of events that occur in the treatment arms combined. Adjustments for multiple comparisons are displayed in a manner to indicate clearly those events for which the difference between treatment arms is statistically significant. Furthermore, adverse events can be displayed by time intervals, with multiple volcano plots or animation to appreciate changes in adverse event risk over time. Such presentations can emphasize early differences across treatments that may resolve later or highlight events for which treatment differences may become more substantial with longer follow-up. Treatment arms are compared in a pairwise fashion. Volcano plots are space-saving tools that emphasize important differences between the adverse event profiles of two treatment arms. They can incorporate multiplicity adjustments in a manner that is straightforward to interpret and, by using time intervals, can illustrate how adverse event risk changes over the course of a clinical trial.

Adverse events are detected by monitoring the patient's status, including blood test results. However, it is difficult to identify all adverse events based on recognition by individual doctors. We developed a system that can be used to detect hematotoxicity adverse events according to blood test results recorded in an electronic medical record system. The blood test results were graded based on Common Terminology Criteria for Adverse Events (CTCAE) and changes in the blood test results (Up, Down, Flat) were assessed according to the variation in the grade. The changes in the blood test and injection data were stored in a database. By comparing the date of injection and start and end dates of the change in the blood test results, adverse events related to a designated drug were detected. Using this method, we searched for the occurrence of serious adverse events (CTCAE Grades 3 or 4) concerning WBC, ALT and creatinine related to paclitaxel at Osaka University Hospital. The rate of occurrence of a decreased WBC count, increased ALT level and increased creatinine level was 36.0%, 0.6% and 0.4%, respectively. This method is useful for detecting and estimating the rate of occurrence of hematotoxicity adverse drug events.
Consumer perceptions of safety in hospitals.

Studies investigating adverse events have traditionally been principally undertaken from a medical perspective. The impact that experience of an adverse event has on consumer confidence in health care is largely unknown. The objectives of the study were to seek public opinion on 1) the rate and severity of adverse events experienced in hospitals; and 2) the perception of safety in hospitals, so that predictors of lack of safety could be identified. A multistage, clustered survey of persons residing in South Australia (2001), using household interviews (weighted n = 2,884). A total of 67% of respondents aged over forty years reported having at least one member of their household hospitalised in the past five years; with the average being two hospital admissions in five years. Respondents stated that 7.0% (95%CI: 6.2% to 7.9%) of those hospital admissions were associated with an adverse event; 59.7% of respondents (95% CI: 51.4% to 67.5%) rated the adverse event as really serious and 48.5% (95% CI: 40.4% to 56.8%) stated prolonged hospitalisation was required as a consequence of the adverse event. Perception of safety in hospitals was largely affected by the experience of an adverse event; really serious events were the most significant predictor of lack of safety in those aged 40 years and over (RR 2.38; p<0.001). The experience of adverse events negatively impacted on public confidence in hospitals. The consumer-reported adverse event rate in hospitals (7.0%) is similar to that identified using medical record review. Based on estimates from other studies, self-reported claims of adverse events in hospital by consumers appear credible, and should be considered when developing appropriate treatment regimes.

Recent life events and psychosis: The role of childhood adversities.
Mansueto, Giovanni; Faravelli, Carlo
2017-10-01
Life events are commonly reported to be related to psychosis. However, less attention has been given to the role that recent events play on psychosis, in relation to exposure to childhood adversity. The current study aimed to evaluate the relationship between recent events and psychosis, taking into account the role of early adversities. 78 psychotic patients and 156 controls were enrolled. Childhood adversity was evaluated using a validated semi-structured interview and the Childhood Experience of Care and Abuse Questionnaire. Recent events were recorded using a semi-structured interview with a normative and contextual approach. The diagnosis of psychosis was made according to Jablenski's criteria. Chi-square, t-test, odds ratio, and binary logistic regression statistical analyses were performed. Psychotic patients reported an excess of recent events. The occurrence of more than one recent event increased the risk of psychosis; there was a cumulative effect between recent and childhood events on psychosis. Recent events were significantly related to psychosis, even in the absence of childhood adversity or when adjusted for it. Our findings suggested that the effect of recent events on psychosis may be amplified by previous exposure to early adversity. Recent events alone, could be also linked to psychosis independently of childhood adversity. Copyright © 2017 Elsevier B.V. All rights reserved.

The Patient Protection and Affordable Care Act of 2010 brought attention to adverse drug events in national patient safety efforts. Updated, detailed, nationally representative data describing adverse drug events can help focus these efforts. To describe the characteristics of emergency department (ED) visits for adverse drug events in the United States in 2013-2014 and describe changes in ED visits for adverse drug events since 2005-2006. Active, nationally representative, public health surveillance in 58 EDs located in the United States and participating in the National Electronic Injury Surveillance System-Cooperative Adverse Drug Event Surveillance project. Drugs implicated in ED visits. National weighted estimates of ED visits and subsequent hospitalizations for adverse drug events. Based on data from 42 585 cases, an estimated 4.0 (95% CI, 3.1-5.0) ED visits for adverse drug events occurred per 1000 individuals annually in 2013 and 2014 and 27.3% (95% CI, 22.2%-32.4%) of ED visits for adverse drug events resulted in hospitalization. An estimated 34.5% (95% CI, 30.3%-38.8%) of ED visits for adverse drug events occurred among adults aged 65 years or older in 2013-2014 compared with an estimated 25.6% (95% CI, 21.1%-30.0%) in 2005-2006; older adults experienced the highest hospitalization rates (43.6%; 95% CI, 36.6%-50.5%). Anticoagulants, antibiotics, and diabetes agents were implicated in an estimated 46.9% (95% CI, 44.2%-49.7%) of ED visits for adverse drug events, which included clinically significant adverse events, such as hemorrhage (anticoagulants), moderate to severe allergic reactions (antibiotics), and hypoglycemia with moderate to severe neurological effects (diabetes agents). Since 2005-2006, the proportions of ED visits for adverse drug events from anticoagulants and diabetes agents have increased, whereas the proportion from antibiotics has decreased. Among children aged 5 years or younger, antibiotics were the most common drug class implicated (56.4%; 95% CI, 51.8%-61.0%). Among children and adolescents aged 6 to 19 years, antibiotics also were the most common drug class implicated (31.8%; 95% CI, 28.7%-34.9%) in ED visits for adverse drug events, followed by antipsychotics (4.5%; 95% CI, 3.3%-5.6%). Among older adults (aged ≥65 years), 3 drug classes (anticoagulants, diabetes agents, and opioid analgesics) were implicated in an estimated 59.9% (95% CI, 56.8%-62.9%) of ED visits for adverse drug events; 4 anticoagulants (warfarin, rivaroxaban, dabigatran, and enoxaparin) and 5 diabetes agents (insulin and 4 oral agents) were among the 15 most common drugs implicated. Medications to always avoid in older adults according to Beers criteria were implicated in 1.8% (95% CI, 1.5%-2.1%) of ED visits for adverse drug events. The prevalence of emergency department visits for adverse drug events in the United States was estimated to be 4 per 1000 individuals in 2013 and 2014. The most common drug classes implicated were anticoagulants, antibiotics, diabetes agents, and opioid analgesics.

Background: detection of adverse events is part of the safety management in hospitalized patients. The objective of this study was to describe the incidence of adverse events that occurred in a pediatric hospital. Methods: cross-sectional study of the adverse events occurred in a pediatric hospital from 2007 to 2009. Factors associated with their developmental causes were identified. The statistical analysis was descriptive and bivariate, with contingency tables to estimate the relationship between those factors. A p value = 0.05 was considered significant. Results: a total of 177 adverse events were registered. When they began, human factor occurred in 23 cases (13 %, OR = 1.41, p = 0.001), organizational factor was present in 71 cases (40 %, OR = 1.91, p = 0.236) and technical factor in 46 cases (26 %, OR = 0.87, p = 0.01). Blows or bruises from falls as a result of adverse events occurred in 71 cases (40 %, 95 % CI = 64-78). Conclusions: we found 1.84 events per 100 hospital discharges during the study period. The fall of patients ranked first of the adverse events identified.

Objective To determine the rate of adverse events associated with endotracheal intubation in newborns and modifiable factors contributing to these events. Study design We conducted a prospective, observational study in a 100-bed, academic, level IV Neonatal Intensive Care Unit (NICU) from September 2013 through June 2014. We collected data on intubations using standardized data collection instruments with validation by medical record review. Intubations in the delivery or operating rooms were excluded. The primary outcome was an intubation with any adverse event. Adverse events were defined and tracked prospectively as non-severe or severe. We measured clinical variables including number of attempts to successful intubation and intubation urgency (elective, urgent or emergent). We used logistic regression models to estimate the association of these variables with adverse events. Results During the study period, 304 intubations occurred in 178 infants. Data were available for 273 intubations (90%) in 162 patients. Adverse events occurred in 107 (39%) intubations with non-severe and severe events in 96 (35%) and 24 (8.8%) intubations, respectively. Increasing number of intubation attempts (odds ratio [OR] 2.1, 95% confidence intervals [CI], 1.6–2.6) and emergent intubations (OR 4.7, 95% CI, 1.7– 13) were predictors of adverse events. The primary cause of emergent intubations was unplanned extubation (62%). Conclusion Adverse events are common in the NICU, occurring in 4 of 10 intubations. The odds of an adverse event doubled with increasing number of attempts and quadrupled in the emergent setting. Quality improvement efforts to address these factors are needed to improve patient safety. PMID:26541424

The electrocardiogram (ECG) is often used to identify which hyperkalemic patients are at risk for adverse events. However, there is a paucity of evidence to support this practice. This study analyzes the association between specific hyperkalemic ECG abnormalities and the development of short-term adverse events in patients with severe hyperkalemia. We collected records of all adult patients with potassium (K+) ≥6.5 mEq/L in the hospital laboratory database from August 15, 2010, through January 30, 2015. A chart review identified patient demographics, concurrent laboratory values, ECG within one hour of K+ measurement, treatments and occurrence of adverse events within six hours of ECG. We defined adverse events as symptomatic bradycardia, ventricular tachycardia, ventricular fibrillation, cardiopulmonary resuscitation (CPR) and/or death. Two emergency physicians blinded to study objective independently examined each ECG for rate, rhythm, peaked T wave, PR interval duration and QRS complex duration. Relative risk was calculated to determine the association between specific hyperkalemic ECG abnormalities and short-term adverse events. We included a total of 188 patients with severe hyperkalemia in the final study group. Adverse events occurred within six hours in 28 patients (15%): symptomatic bradycardia (n=22), death (n=4), ventricular tachycardia (n=2) and CPR (n=2). All adverse events occurred prior to treatment with calcium and all but one occurred prior to K + -lowering intervention. All patients who had a short-term adverse event had a preceding ECG that demonstrated at least one hyperkalemic abnormality (100%, 95% confidence interval [CI] [85.7-100%]). An increased likelihood of short-term adverse event was found for hyperkalemic patients whose ECG demonstrated QRS prolongation (relative risk [RR] 4.74, 95% CI [2.01-11.15]), bradycardia (HR<50) (RR 12.29, 95%CI [6.69-22.57]), and/or junctional rhythm (RR 7.46, 95%CI 5.28-11.13). There was no statistically significant correlation between peaked T waves and short-term adverse events (RR 0.77, 95% CI [0.35-1.70]). Our findings support the use of the ECG to risk stratify patients with severe hyperkalemia for short-term adverse events.

Introduction The electrocardiogram (ECG) is often used to identify which hyperkalemic patients are at risk for adverse events. However, there is a paucity of evidence to support this practice. This study analyzes the association between specific hyperkalemic ECG abnormalities and the development of short-term adverse events in patients with severe hyperkalemia. Methods We collected records of all adult patients with potassium (K+) ≥6.5 mEq/L in the hospital laboratory database from August 15, 2010, through January 30, 2015. A chart review identified patient demographics, concurrent laboratory values, ECG within one hour of K+ measurement, treatments and occurrence of adverse events within six hours of ECG. We defined adverse events as symptomatic bradycardia, ventricular tachycardia, ventricular fibrillation, cardiopulmonary resuscitation (CPR) and/or death. Two emergency physicians blinded to study objective independently examined each ECG for rate, rhythm, peaked T wave, PR interval duration and QRS complex duration. Relative risk was calculated to determine the association between specific hyperkalemic ECG abnormalities and short-term adverse events. Results We included a total of 188 patients with severe hyperkalemia in the final study group. Adverse events occurred within six hours in 28 patients (15%): symptomatic bradycardia (n=22), death (n=4), ventricular tachycardia (n=2) and CPR (n=2). All adverse events occurred prior to treatment with calcium and all but one occurred prior to K+-lowering intervention. All patients who had a short-term adverse event had a preceding ECG that demonstrated at least one hyperkalemic abnormality (100%, 95% confidence interval [CI] [85.7–100%]). An increased likelihood of short-term adverse event was found for hyperkalemic patients whose ECG demonstrated QRS prolongation (relative risk [RR] 4.74, 95% CI [2.01–11.15]), bradycardia (HR<50) (RR 12.29, 95%CI [6.69–22.57]), and/or junctional rhythm (RR 7.46, 95%CI 5.28–11.13). There was no statistically significant correlation between peaked T waves and short-term adverse events (RR 0.77, 95% CI [0.35–1.70]). Conclusion Our findings support the use of the ECG to risk stratify patients with severe hyperkalemia for short-term adverse events. PMID:28874951

Children often present to the emergency department (ED) with minor conditions such as fever and have persistently abnormal vital signs. We hypothesized that a significant portion of children discharged from the ED would have abnormal vital signs and that those discharged with abnormal vital signs would experience very few adverse events. We performed a retrospective chart review encompassing a 44-month period of all pediatric patients (aged two months to 17 years) who were discharged from the ED with an abnormal pulse rate, respiratory rate, temperature, or oxygen saturation. We used a local quality assurance database to identify pre-defined adverse events after discharge in this population. Our primary aim was to determine the proportion of children discharged with abnormal vital signs and the frequency and nature of adverse events. Additionally, we performed a sub-analysis comparing the rate of adverse events in children discharged with normal vs. abnormal vital signs, as well as a standardized review of the nature of each adverse event. Of 33,185 children discharged during the study period, 5,540 (17%) of these patients had at least one abnormal vital sign. There were 24/5,540 (0.43%) adverse events in the children with at least one abnormal vital sign vs. 47/27,645 (0.17%) adverse events in the children with normal vital signs [relative risk = 2.5 (95% confidence interval, 1.6 to 2.4)].However, upon review of each adverse event we found only one case that was related to the index visit, was potentially preventable by a 23-hour hospital observation, and caused permanent disability. In our study population, 17% of the children were discharged with at least one abnormal vital sign, and there were very few adverse (0.43%) events associated with this practice. Heart rate was the most common abnormal vital sign leading to an adverse event. Severe adverse events that were potentially related to the abnormal vital sign(s) were exceedingly rare. Additional research is needed in broader populations to better determine the rate of adverse events and possible methods of avoiding them.

International guidelines recommend ethical and scientific quality standards for managing and reporting adverse events occurring during clinical trials to competent research ethics committees and regulatory authorities. The purpose of this study was to determine whether clinical trial protocols in Cameroon are developed in line with national requirements and international guidelines as far as detecting, reporting and investigating of adverse events is concerned. It was a documentary review of all approved clinical trial protocols that were submitted at the Cameroon National Ethics Committee for evaluation from 1997 through 2012. Data were extracted using a preconceived and validated grid. Protocol review process targeted the title, abstract, objectives, methodology, resources, and the chapter on safety. In total, 106 (4.9 %) clinical trial protocols were identified from 2173 protocols seen in the archive and 104 (4.8 %) included for review. Seventy six (73.1 %) trials did not include the surveillance of adverse events as part of their objective. A total of 91 (87.5 %) protocols did not budget for adverse event surveillance, 76 (73.1 %) did not have a data safety management board (DSMB), 11(10.6 %) included insurance for participants, 47 (45.2 %) did not include a case definition for serious adverse events, 33 (31.7 %) described procedures to detect adverse events, 33 (31.7 %) described procedure for reporting and 22 (21.2 %) described procedure for investigating adverse events. Most clinical trial protocols in Cameroon are developed to focus on benefits and pay little attention to harms. The development of national guidelines can improve the surveillance of adverse events in clinical trial research conducted in Cameroon. Adverse events surveillance tools and a budget are critical for an adequate planning for adverse event surveillance when developing trial protocols. Clinical trial protocols submitted in the Cameroon National Ethics Committee do not adequately plan to assess adverse events in clinical trial protocols. In order to improve on the safety of participants and marketed drug, there is a need to develop national guidelines for clinical trials by the government, and to improve evaluation procedures and monitoring of ongoing trials by the ethics committee.

Objective Nevirapine is widely prescribed for HIV-1 infection. We characterized relationships between nevirapine-associated cutaneous and hepatic adverse events and genetic variants among HIV-infected adults. Design We retrospectively identified cases and controls. Cases experienced symptomatic nevirapine-associated severe (grade III/IV) cutaneous and/or hepatic adverse events within 8 weeks of initiating nevirapine. Controls did not experience adverse events during more than 18 weeks of nevirapine therapy. Methods Cases and controls were matched 1 : 2 on baseline CD4 T-cell count, sex, and race. Individuals with 150 or less CD4 T cells/μl at baseline were excluded. We characterized 123 human leukocyte antigen (HLA) alleles and 2744 single-nucleotide polymorphisms in major histocompatibility complex (MHC) and drug metabolism and transport genes. Results We studied 276 evaluable cases (175 cutaneous adverse events, 101 hepatic adverse events) and 587 controls. Cutaneous adverse events were associated with CYP2B6 516G→T (OR 1.66, all), HLA-Cw*04 (OR 2.51, all), and HLA-B*35 (OR 3.47, Asians; 5.65, Thais). Risk for cutaneous adverse events was particularly high among Blacks with CYP2B6 516TT and HLA-Cw*04 (OR 18.90) and Asians with HLA-B*35 and HLA-Cw*04 (OR 18.34). Hepatic adverse events were associated with HLA-DRB*01 (OR 3.02, Whites), but not CYP2B6 genotypes. Associations differed by population, at least in part reflecting allele frequencies. Conclusion Among patients with at least 150 CD4 T cells/μl, polymorphisms in drug metabolism and immune response pathways were associated with greater likelihood of risk for nevirapine-related adverse events. Results suggest fundamentally different mechanisms of adverse events: cutaneous, most likely MHC class I-mediated, influenced by nevirapine CYP2B6 metabolism; hepatic, most likely MHC class II-mediated and unaffected by such metabolism. These risk variants are insensitive for routine clinical screening. PMID:21505298

Objective: To determine the prevalence of adverse events in elderly trauma patients with isolated blunt thoracic trauma, and to identify variables associated with these adverse events. Methods: We performed a chart review of 160 trauma patients age 65 and older with significant blunt thoracic trauma, drawn from an American College of Surgeons Level I Trauma Center registry. Patients with serious injury to other body areas were excluded to prevent confounding the cause of adverse events. Adverse events were defined as acute respiratory distress syndrome or pneumonia, unanticipated intubation, transfer to the intensive care unit for hypoxemia, or death. Data collected included history, physical examination, radiographic findings, length of hospital stay, and clinical outcomes. Results: Ninety-nine patients had isolated chest injury, while 61 others had other organ systems injured and were excluded. Sixteen patients developed adverse events [16.2% 95% confidence interval (CI) 9.5–24.9%], including two deaths. Adverse events were experienced by 19.2%, 6.1%, and 28.6% of those patients 65–74, 75–84, and ≥85 years old, respectively. The mean length of stay was 14.6 days in patients with an adverse event and 5.8 days in patients without. Post hoc analysis revealed that all 16 patients with an adverse event had one or more of the following: age ≥85, initial systolic blood pressure <90 mmHg, hemothorax, pneumothorax, three or more unilateral rib fractures, or pulmonary contusion (sensitivity 100%, CI 79.4–100%; specificity 38.6%, CI 28.1–49.9%). Conclusion: Adverse events from isolated thoracic trauma in elderly patients complicate 16% of our sample. These criteria were 100% sensitive and 38.5% specific for these adverse events. This study is a first step to identifying variables that might aid in identifying patients at high risk for serious adverse events. PMID:19561823

Objective Adverse events in childhood can indelibly influence adult health. While evidence for this association has mounted, a fundamental set of questions about how to operationalize adverse events has been understudied. Method We used data from the National Survey of Midlife Development in the United States to examine how quantity, timing, and types of adverse events in childhood are associated with adult cardiometabolic health. Results The best-fitting specification of quantity of events was a linear measure reflecting a dose–response relationship. Timing of event mattered less than repeated exposure to events. Regarding the type of event, academic interruptions and sexual/physical abuse were most important. Adverse childhood events elevated the risk of diabetes and obesity similarly for men and women but had a greater impact on women’s risk of heart disease. Discussion Findings demonstrate the insights that can be gleaned about the early-life origins of adult health by examining operationalization of childhood exposures. PMID:25903978

The Clinical Narrative Temporal Relation Ontology (CNTRO)1 project offers a semantic-web based reasoning framework, which represents temporal events and relationships within clinical narrative texts, and infer new knowledge over them. In this paper, the CNTRO reasoning framework is applied to temporal analysis of medical device adverse event files. One specific adverse event was used as a test case: late stent thrombosis. Adverse event narratives were obtained from the Food and Drug Administration's (FDA) Manufacturing and User Facility Device Experience (MAUDE) database2. 15 adverse event files in which late stent thrombosis was confirmed were randomly selected across multiple drug eluting stent devices. From these files, 81 events and 72 temporal relations were annotated. 73 temporal questions were generated, of which 65 were correctly answered by the CNTRO system. This results in an overall accuracy of 89%. This system should be pursued further to continue assessing its potential benefits in temporal analysis of medical device adverse events.

Before creation and validation of the FACE-Q by Pusic et al., adverse event types and incidences following facial cosmetic procedures were objectively measured and reported by physicians, potentially leading to misrepresentation of the true patient experience. This article analyzes and compares adverse event data from both FACE-Q and recent review articles, incorporating patient-reported adverse event data to improve patient preparation for facial cosmetic procedures. FACE-Q adverse event data were extracted from peer-reviewed validation articles for face lift, rhinoplasty, and blepharoplasty, and these data were compared against adverse effect risk data published in recent Continuing Medical Education/Maintenance of Certification and other articles regarding the same procedures. The patient-reported adverse event data sets and the physician-reported adverse event data sets do contain overlapping elements, but each data set also contains unique elements. The data sets represent differing viewpoints. Furthermore, patient-reported outcomes from the FACE-Q provided incidence data that were otherwise previously not reported. In the growing facial cosmetic surgery industry, patient perspective is critical as a determinant of success; therefore, incorporation of evidence-based patient-reported outcome data will not only improve patient expectations and overall experience, but will also reveal adverse event incidences that were previously unknown. Given that there is incomplete overlap between patient-reported and physician-reported adverse events, presentation of both data sets in the consultation setting will improve patient preparation. Furthermore, use of validated tools such as the FACE-Q will allow surgeons to audit themselves critically.

Adverse events associated with overtube-assisted enteroscopy are similar to those with routine endoscopy. Our endoscopy quality program identified a number of respiratory adverse events resulting in emergency resuscitation efforts. The aim is to report all adverse events identified by quality monitoring and outcomes of adverse events associated with overtube-assisted enteroscopy. A retrospective study used data prospectively obtained from consecutive patients undergoing overtube-assisted enteroscopy between December 2008 and July 2012. Patient characteristics, medical history, procedure indication, and procedure outcomes, including diagnosis, endoscopic therapy, and complications, were obtained. In 432 overtube-assisted enteroscopies, 15 adverse events (most frequently hypoxemia, 9 /15, 60 %) occurred in 14 patients (3.2 % of total cohort; 12 were outpatients) mostly during antegrade enteroscopy. Four patients required endotracheal intubation and 4 /12 outpatients required intensive care. The procedure was aborted in 13 /14 patients, and only 1 of 10 patients scheduled for repeat antegrade enteroscopy returned. There was no mortality. Based on the frequency of adverse events, and in consultation with anesthesia providers, from August 2012 all antegrade overtube-assisted enteroscopies at our institution were done with general anesthesia. From then till September 2013, 145 antegrade and 52 retrograde overtube-assisted enteroscopies have been done, with no adverse events. Monitoring of endoscopy practice identified adverse events associated with overtube-assisted enteroscopy. The peer-review prompted a change in practice: all patients undergoing antegrade overtube-assisted enteroscopy at our institution now have endotracheal intubation which has dramatically decreased the rate of respiratory adverse events. The impact of endoscopic quality measurements on practices, procedures, and outcomes will be of further interest. © Georg Thieme Verlag KG Stuttgart · New York.

Adverse event reports (AERs) submitted to the US Food and Drug Administration (FDA) were reviewed to assess the muscular and renal adverse events induced by the administration of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) and to attempt to determine the rank-order of the association. After a revision of arbitrary drug names and the deletion of duplicated submissions, AERs involving pravastatin, simvastatin, atorvastatin, or rosuvastatin were analyzed. Authorized pharmacovigilance tools were used for quantitative detection of signals, i.e., drug-associated adverse events, including the proportional reporting ratio, the reporting odds ratio, the information component given by a Bayesian confidence propagation neural network, and the empirical Bayes geometric mean. Myalgia, rhabdomyolysis and an increase in creatine phosphokinase level were focused on as the muscular adverse events, and acute renal failure, non-acute renal failure, and an increase in blood creatinine level as the renal adverse events. Based on 1,644,220 AERs from 2004 to 2009, signals were detected for 4 statins with respect to myalgia, rhabdomyolysis, and an increase in creatine phosphokinase level, but these signals were stronger for rosuvastatin than pravastatin and atorvastatin. Signals were also detected for acute renal failure, though in the case of atorvastatin, the association was marginal, and furthermore, a signal was not detected for non-acute renal failure or for an increase in blood creatinine level. Data mining of the FDA's adverse event reporting system, AERS, is useful for examining statin-associated muscular and renal adverse events. The data strongly suggest the necessity of well-organized clinical studies with respect to statin-associated adverse events.

Our objective was to define the relationship between surgical technical performance score, intraoperative adverse events, and major postoperative adverse events in complex pediatric cardiac repairs. Infants younger than 6 months were prospectively followed up until discharge from the hospital. Technical performance scores were graded as optimal, adequate, or inadequate based on discharge echocardiograms and need for reintervention after initial surgery. Case complexity was determined by Risk Adjustment in Congenital Heart Surgery (RACHS-1) category, and preoperative illness severity was assessed by Pediatric Risk of Mortality (PRISM) III score. Intraoperative adverse events were prospectively monitored. Outcomes were analyzed using nonparametric methods and a logistic regression model. A total of 166 patients (RACHS 4-6 [49%]), neonates [50%]) were observed. Sixty-one (37%) had at least 1 intraoperative adverse event, and 47 (28.3%) had at least 1 major postoperative adverse event. There was no correlation between intraoperative adverse events and RACHS, preoperative PRISM III, technical performance score, or postoperative adverse events on multivariate analysis. For the entire cohort, better technical performance score resulted in lower postoperative adverse events, lower postoperative PRISM, and lower length of stay and ventilation time (P < .001). Patients requiring intraoperative revisions fared as well as patients without, provided the technical score was at least adequate. In neonatal and infant open heart repairs, technical performance score is one of the main predictors of postoperative morbidity. Outcomes are not affected by intraoperative adverse events, including surgical revisions, provided technical performance score is at least adequate.

Lessons learnt from Dental Patient Safety Case Reports

Background Errors are commonplace in dentistry, it is therefore our imperative as dental professionals to intercept them before they lead to an adverse event, and/or mitigate their effects when an adverse event occurs. This requires a systematic approach at both the profession-level, encapsulated in the Agency for Healthcare Research and Quality’s Patient Safety Initiative structure, as well as at the practice-level, where Crew Resource Management is a tested paradigm. Supporting patient safety at both the dental practice and profession levels relies on understanding the types and causes of errors, an area in which little is known. Methods A retrospective review of dental adverse events reported in the literature was performed. Electronic bibliographic databases were searched and data were extracted on background characteristics, incident description, case characteristics, clinic setting where adverse event originated, phase of patient care that adverse event was detected, proximal cause, type of patient harm, degree of harm and recovery actions. Results 182 publications (containing 270 cases) were identified through our search. Delayed and unnecessary treatment/disease progression after misdiagnosis was the largest type of harm reported. 24.4% of reviewed cases were reported to have experienced permanent harm. One of every ten case reports reviewed (11.1%) reported that the adverse event resulted in the death of the affected patient. Conclusions Published case reports provide a window into understanding the nature and extent of dental adverse events, but for as much as the findings revealed about adverse events, they also identified the need for more broad-based contributions to our collective body of knowledge about adverse events in the dental office and their causes. Practical Implications Siloed and incomplete contributions to our understanding of adverse events in the dental office are threats to dental patients’ safety. PMID:25925524

Large cohort studies have shown a high rate of first-line combination antiretroviral therapy (cART) regimen discontinuation in HIV-infected patients, attributed to characteristics of the cART regimen or toxicity. A cohort study of 274 patients receiving a first-line regimen was carried out. Patients' perceptions and beliefs prior to initiation were assessed using an attitude towards medication scale (0-15 points), and their satisfaction during therapy was assessed using an HIV treatment satisfaction questionnaire (HIVTSQ). Treatment discontinuation was defined as any switch in the cART regimen. During 474.8 person-years of follow-up, 63 (23%) patients changed their cART regimen, mainly because of toxicity/intolerance (42; 67%). The overall rate of change was 13.2 per 100 patient-years [95% confidence interval (CI) 11.1-16.4 per 100 patient-years]. An efavirenz (EFV)-based single tablet regimen showed the highest rate of adverse events (27%), but the lowest rate of change (16%; 7.44 per 100 patient-years). Cox regression revealed a decreased hazard of first regimen termination with better initial attitude towards drugs [hazard ratio (HR) 0.76; 95% CI 0.62-0.93; P < 0.01] and higher satisfaction (HR 0.94; 95% CI 0.89-0.99; P = 0.01), and an increased hazard of termination with the presence of adverse events (HR 7.7; 95% CI 2.4-11.6; P < 0.01). One-third of patients (18 of 59; 31%) with mild/moderate adverse events (which were mainly central nervous system symptoms) continued the regimen; these patients, compared with those discontinuing therapy, showed better perception of therapy (mean score 14.4 versus 12.1, respectively; P = 0.05) and greater satisfaction during therapy (mean score 50.6 versus 44.6, respectively; P = 0.04). Patients' beliefs and satisfaction with therapy influence the durability of the first antiretroviral regimen. These patient-related factors modulate the impact of mild adverse events, and could explain differences in the rate of discontinuation. © 2015 British HIV Association.

Past research provides strong evidence that adverse life events heighten the risk of delinquent behavior among adolescents. Urban informal (slum) settlements in sub-Saharan Africa are marked by extreme adversity. However, the prevalence and consequences of adverse life events as well as protective factors that can mitigate the effects of exposure to these events in slum settlements is largely understudied. We examine two research questions. First, are adverse life events experienced at the individual and household level associated with a higher likelihood of delinquent behavior among adolescents living in two slums in Nairobi, Kenya? Second, are parental monitoring, religiosity, and self-esteem protective against delinquency in a context of high adversity? We used cross-sectional data from 3,064 males and females aged 12-19 years who participated in the Transitions to Adulthood Study. We examined the extent to which a composite index of adverse life events was associated with delinquent behavior (measured using a composite index derived from nine items). We also examined the direct and moderating effects of three protective factors: parental monitoring, religiosity, and self-esteem. Fifty-four percent of adolescents reported at least one adverse life event, while 18% reported three or more adverse events. For both males and females, adversity was positively and significantly associated with delinquency in bivariate and multivariate models. Negative associations were observed between the protective factors and delinquency. Significant adverse events × protective factor interaction terms were observed for parental monitoring (females and males), religiosity (males), and self-esteem (females). Similar to research in high income countries, adverse life events are associated with an increased likelihood of delinquent behavior among adolescents living in urban slums in Kenya, a low-income country. However, parental monitoring, religiosity, and self-esteem may moderate the effect of adversity on delinquent behavior and pinpoint possible avenues to develop interventions to reduce delinquency in resource-poor settings in low and middle income countries.

Purpose: To determine whether acute kidney injury (AKI) is identified within the US Food and Drug Administration's Adverse Events and Reporting System (FDA AERS) as an adverse event resulting from bisphosphonate (BP) use in cancer therapy. Methods: A search of the FDA AERS records from January 1998 through June 2009 was performed; search terms were “renal problems” and all drug names for BPs. The search resulted in 2,091 reports. We analyzed for signals of disproportional association by calculating the proportional reporting ratio for zoledronic acid (ZOL) and pamidronate. Literature review of BP-associated renal injury within the cancer setting was conducted. Results: Four hundred eighty cases of BP-associated acute kidney injury (AKI) were identified in patients with cancer. Two hundred ninety-eight patients (56%) were female; mean age was 66 ± 10 years. Multiple myeloma (n = 220, 46%), breast cancer (n = 98, 20%), and prostate cancer (n = 24, 5%) were identified. Agents included ZOL (n = 411, 87.5%), pamidronate (n = 8, 17%), and alendronate (n = 36, 2%). Outcomes included hospitalization (n = 304, 63.3%) and death (n = 68, 14%). The proportional reporting ratio for ZOL was 1.22 (95% CI, 1.13 to 1.32) and for pamidronate was 1.55 (95% CI, 1.25 to 1.65), reflecting a nonsignificant safety signal for both drugs. Conclusion: AKI was identified in BP cancer clinical trials, although a safety signal for BPs and AKI within the FDA AERS was not detected. Our findings may be attributed, in part, to clinicians who believe that AKI occurs infrequently; ascribe the AKI to underlying premorbid disease, therapy, or cancer progression; or consider that AKI is a known adverse drug reaction of BPs and thus under-report AKI to the AERS.

Burden of Clostridium difficile on the healthcare system.
Dubberke, Erik R; Olsen, Margaret A
2012-08-01
There are few high-quality studies of the costs of Clostridium difficile infection (CDI), and the majority of studies focus on the costs of CDI in acute-care facilities. Analysis of the best available data, from 2008, indicates that CDI may have resulted in $4.8 billion in excess costs in US acute-care facilities. Other areas of CDI-attributable excess costs that need to be investigated are costs of increased discharges to long-term care facilities, of CDI with onset in long-term care facilities, of recurrent CDI, and of additional adverse events caused by CDI.

Adverse events are an important but understudied area in dentistry. Most dentists will face the issue of an adverse event several times in their clinical careers. The authors implemented a six-hour pilot educational module at one dental school to improve fourth-year dental students' knowledge and confidence in communicating with patients about adverse events. Based on results from the twenty-nine students who completed both the pre- and posttests, the module significantly increased the students' knowledge of the key concepts involved in adverse events. However, the module did not improve the students' confidence that they would be able to implement these communication skills in clinical situations. Based on these results, this article discusses how future educational efforts can be modified to better prepare students for the communication challenges associated with adverse events.

To determine the incidence of adverse events in ferrets vaccinated with a modified-live avian cell culture canine distemper virus vaccine licensed for use in ferrets, an inactivated rabies vaccine licensed for use in ferrets, or both. Retrospective study. 143 ferrets. Medical records were reviewed to identify ferrets that had an adverse event after vaccination. Adverse events developed within 25 minutes after vaccination in 13 ferrets. One ferret developed an adverse event after receiving a distemper and a rabies vaccine simultaneously and developed a second adverse event the following year after receiving the rabies vaccine alone. Therefore, a total of 14 adverse events were identified. All adverse events were an anaphylactic reaction characterized by generalized hyperemia, hypersalivation, and vomiting. Ten of the 14 anaphylactic reactions occurred after ferrets received both vaccines, 3 occurred after ferrets received the distemper vaccine alone, and 1 occurred after a ferret received the rabies vaccine alone. Incidences of adverse events after administration of both vaccines, the distemper vaccine alone, and the rabies vaccine alone were 5.6, 5.9, and 5.6%, respectively. Ferrets that had an anaphylactic reaction were significantly older at the time of vaccination than were ferrets that did not. Results suggest that there may be a high incidence of anaphylactic reactions after vaccination of domestic ferrets. Ferrets should be observed for at least 25 minutes after vaccination, and veterinarians who vaccinate ferrets should be prepared to treat anaphylactic reactions.

Background The Food and Drug Administration’s (FDA) Adverse Event Reporting System (FAERS) is a repository of spontaneously-reported adverse drug events (ADEs) for FDA-approved prescription drugs. FAERS reports include both structured reports and unstructured narratives. The narratives often include essential information for evaluation of the severity, causality, and description of ADEs that are not present in the structured data. The timely identification of unknown toxicities of prescription drugs is an important, unsolved problem. Objective The objective of this study was to develop an annotated corpus of FAERS narratives and biomedical named entity tagger to automatically identify ADE related information in the FAERS narratives. Methods We developed an annotation guideline and annotate medication information and adverse event related entities on 122 FAERS narratives comprising approximately 23,000 word tokens. A named entity tagger using supervised machine learning approaches was built for detecting medication information and adverse event entities using various categories of features. Results The annotated corpus had an agreement of over .9 Cohen’s kappa for medication and adverse event entities. The best performing tagger achieves an overall performance of 0.73 F1 score for detection of medication, adverse event and other named entities. Conclusions In this study, we developed an annotated corpus of FAERS narratives and machine learning based models for automatically extracting medication and adverse event information from the FAERS narratives. Our study is an important step towards enriching the FAERS data for postmarketing pharmacovigilance. PMID:25600332

We aimed to compare clinical outcomes and early adverse events of operative management (OM), nonoperative management (NOM), and NOM with splenic artery embolization (SAE) in blunt splenic injury (BSI) and identify the prognostic factors. Medical records of 136 consecutive patients with BSI admitted to a trauma center from 2005 to 2010 were retrospectively reviewed. Patients were separated into three groups: OM, NOM, and SAE. We focused on associated injuries and early adverse events. Multivariate analysis was performed on 23 prognostic factors to find predictors. The total survival rate was 97.1%, with four deaths all occurred in the OM group. The spleen salvage rate was 91% in NOM and SAE. At least one adverse event was observed in 32.8%, 62%, and 96% of patients in NOM, SAE, and OM groups, respectively (P < 0.001). We found significantly more deaths, infectious complications, pleural drainage, acute renal failures, and pancreatitis in OM and more pseudocysts in SAE. Six prognostic factors were statistically significant for one or more adverse events: simplified acute physiology score 2 ≥25 for almost all adverse events, age ≥50 years for acute respiratory syndrome, limb fracture for secondary bleeding, thoracic injury for pleural drainage, and at least one associated injury for pseudocyst. Adverse events were not related to the type of BSI management. Patients with BSI present worse outcome and more adverse events in OM, but this is related to the severity of injury. The main predictor of adverse events remains the severity of injury.

To evaluate the incidence and costs of adverse events registered in an administrative dataset in Spanish hospitals from 2008 to 2010. A retrospective study was carried out that estimated the incremental cost per episode, depending on the presence of adverse events. Costs were obtained from the database of the Spanish Network of Hospital Costs. This database contains data from 12 hospitals that have costs per patient records based on activities and clinical records. Adverse events were identified through the Patient Safety Indicators (validated in the Spanish Health System) created by the Agency for Healthcare Research and Quality together with indicators of the EuroDRG European project. This study included 245,320 episodes with a total cost of 1,308,791,871€. Approximately 17,000 patients (6.8%) experienced an adverse event, representing 16.2% of the total cost. Adverse events, adjusted by diagnosis-related groups, added a mean incremental cost of between €5,260 and €11,905. Six of the 10 adverse events with the highest incremental cost were related to surgical interventions. The total incremental cost of adverse events was € 88,268,906, amounting to an additional 6.7% of total health expenditure. Assessment of the impact of adverse events revealed that these episodes represent significant costs that could be reduced by improving the quality and safety of the Spanish Health System.

Reporting adverse events is a critical element of a clinical trial publication. In 2003, the Consolidated Standards of Reporting Trials (CONSORT) group generated recommendations regarding the appropriate reporting of adverse events. The degree to which these recommendations are followed in oncology publications has not been comprehensively evaluated. A review of citations from PubMed, Medline, and Embase published between Jan 1, 2009 and December 31, 2011, identified eligible randomized, controlled phase III trials in metastatic solid malignancies. Publications were assessed for 14 adverse event-reporting elements derived from the CONSORT harms extension statement; a completeness score (range, 0 to 14) was calculated by adding the number of elements reported. Linear regression analysis identified which publication characteristics associated with reporting completeness. A total of 175 publications, with data for 96,125 patients, were included in the analysis. The median completeness score was eight (range, three to 12). Most publications (96%) reported only adverse events occurring above a threshold rate or severity, 37% did not specify the criteria used to select which adverse events were reported, and 88% grouped together adverse events of varying severity. Regression analysis revealed that trials without a stated funding source and with an earlier year of publication had significantly lower completeness scores. Reporting of adverse events in oncology publications of randomized trials is suboptimal and characterized by substantial selectivity and heterogeneity. The development of oncology-specific standards for adverse event reporting should be established to ensure consistency and provide critical information required for medical decision-making.

In 2007 the federal government began requiring drug makers to include in their print direct-to-consumer advertisements information for consumers on how to contact the Food and Drug Administration directly, either by phone or through the agency's website, to report any adverse events that they experienced after taking a prescription drug. Adverse events can range from minor skin problems like itching to serious injuries or illness that result in hospitalization, permanent disability, or even death. Even so, current rates of adverse event reporting are low. We studied adverse event reports about 123 drugs that came from patients before and after the enactment of the print advertising requirement and estimated that requirement's impact with model simulations. We found that if monthly spending on print direct-to-consumer advertising increased from zero to $7.7 million per drug, the presence of the Food and Drug Administration contact information tripled the increase in patient-reported adverse events, compared to what would have happened in the absence of the law. However, the absolute monthly increase was fewer than 0.24 reports per drug, suggesting that the public health impact of the increase was small and that the adverse event reporting rate would still be low. The study results suggest that additional measures, such as more publicity about the Adverse Event Reporting System or more consumer education, should be considered to promote patient reporting of adverse events.
Committee Opinion No. 681: Disclosure and Discussion of Adverse Events.
2016-12-01
Adverse outcomes, preventable or otherwise, are a reality of medical care. Most importantly, adverse events affect patients, but they also affect health care practitioners. Disclosing information about adverse events has benefits for the patient and the physician and, ideally, strengthens the patient-physician relationship and promotes trust. Studies show that after an adverse outcome, patients expect and want timely and full disclosure of the event, an acknowledgment of responsibility, an understanding of what happened, expressions of sympathy, and a discussion of what is being done to prevent recurrence. Surveys have shown that patients are less likely to pursue litigation if they perceive that the event was honestly disclosed. Barriers to full disclosure are many and include fear of retribution for reporting an adverse event, lack of training, a culture of blame, and fear of lawsuits. To reduce these concerns, it is recommended that health care facilities establish a nonpunitive, blame-free culture that encourages staff to report adverse events and near misses (close calls) without fear of retaliation. Health care institutions should have written policies that address the management of adverse events. Having a responsive process to inform and aid the patient, loved ones, and practitioners is required. A commitment on the part of all health care practitioners and institutions to establish programs and develop the tools needed to help patients, families, health care practitioners, and staff members deal with adversity is essential.

Sunitinib, a vascular endothelial growth factor pathway inhibitor, is an effective treatment for metastatic renal-cell carcinoma. We sought to determine the efficacy and safety of sunitinib in patients with locoregional renal-cell carcinoma at high risk for tumor recurrence after nephrectomy. In this randomized, double-blind, phase 3 trial, we assigned 615 patients with locoregional, high-risk clear-cell renal-cell carcinoma to receive either sunitinib (50 mg per day) or placebo on a 4-weeks-on, 2-weeks-off schedule for 1 year or until disease recurrence, unacceptable toxicity, or consent withdrawal. The primary end point was disease-free survival, according to blinded independent central review. Secondary end points included investigator-assessed disease-free survival, overall survival, and safety. The median duration of disease-free survival was 6.8 years (95% confidence interval [CI], 5.8 to not reached) in the sunitinib group and 5.6 years (95% CI, 3.8 to 6.6) in the placebo group (hazard ratio, 0.76; 95% CI, 0.59 to 0.98; P=0.03). Overall survival data were not mature at the time of data cutoff. Dose reductions because of adverse events were more frequent in the sunitinib group than in the placebo group (34.3% vs. 2%), as were dose interruptions (46.4% vs. 13.2%) and discontinuations (28.1% vs. 5.6%). Grade 3 or 4 adverse events were more frequent in the sunitinib group (48.4% for grade 3 events and 12.1% for grade 4 events) than in the placebo group (15.8% and 3.6%, respectively). There was a similar incidence of serious adverse events in the two groups (21.9% for sunitinib vs. 17.1% for placebo); no deaths were attributed to toxic effects. Among patients with locoregional clear-cell renal-cell carcinoma at high risk for tumor recurrence after nephrectomy, the median duration of disease-free survival was significantly longer in the sunitinib group than in the placebo group, at a cost of a higher rate of toxic events.

Background Up to 50% of adverse events that occur in hospitals are preventable. Language barriers and disabilities that affect communication have been shown to decrease quality of care. We sought to assess whether communication problems are associated with an increased risk of preventable adverse events. Methods We randomly selected 20 general hospitals in the province of Quebec with at least 1500 annual admissions. Of the 145 672 admissions to the selected hospitals in 2000/01, we randomly selected and reviewed 2355 charts of patients aged 18 years or older. Reviewers abstracted patient characteristics, including communication problems, and details of hospital admission, and assessed the cause and preventability of identified adverse events. The primary outcome was adverse events. Results Of 217 adverse events, 63 (29%) were judged to be preventable, for an overall population rate of 2.7% (95% confidence interval [CI] 2.1%–3.4%). We found that patients with preventable adverse events were significantly more likely than those without such events to have a communication problem (odds ratio [OR] 3.00; 95% CI 1.43–6.27) or a psychiatric disorder (OR 2.35; 95% CI 1.09–5.05). Patients who were admitted urgently were significantly more likely than patients whose admissions were elective to experience an event (OR 1.64, 95% CI 1.07–2.52). Preventable adverse events were mainly due to drug errors (40%) or poor clinical management (32%). We found that patients with communication problems were more likely than patients without these problems to experience multiple preventable adverse events (46% v. 20%; p = 0.05). Interpretation Patients with communication problems appeared to be at highest risk for preventable adverse events. Interventions to reduce the risk for these patients need to be developed and evaluated. PMID:18519903

The use of survey data to measure and monitor health and productivity differences between groups is an issue of increasing importance. This article examines the capacity of productivity self-reports (derived from surveys) and adverse event measures (derived from administrative sources) to differentiate groups with a priori known characteristics. A replication strategy is used to test the contributions that productivity self-reports make, alone as well as above and beyond measures of adverse events, to the discrimination of 5 pairs of groups classified by clinical, job type, and demographic criteria. These tests are conducted on representative samples of the active, largely blue-collar employee population at International Truck and Engine Corporation. The results show that both productivity self-reports and adverse event measures differentiate and track known groups. Even in the presence of highly significant effects from adverse event measures, self-reports improve the assessment of productivity. We conclude that: 1) although the joint use of self-reports and adverse event measures is the better approach, practitioners can use self-reports with the expectation that this method will track group differences in health and productivity when adverse event measures are not available; and 2) survey self-reports make unique and independent contributions when adverse events measures are used.

The occurrence of an event planned or unplanned during anesthesia is a concern for staff. This event may jeopardize the success of surgery gesture. Pediatric Surgery therefore has its own specific complications that it requires anesthesia. To evaluate the incidence of adverse events during anesthesia in pediatric surgery scheduled. Descriptive non-randomized study. Descriptive non-randomized study on adverse events related to anesthesia in children over a period of seven months. It took place in the anesthesia and intensive care unit and the pediatric surgery unit of Gabriel Toure hospital in Bamako. It focused on patients aged 0 to 12 years scheduled for surgery under general anesthesia during the study period. Sixty six percent of patients selected was male gender with a sex ratio of 3 in favor of males. The average age was 2 years with extremes of 16 days and 12 years and a standard deviation of 2.93. The old history of premature was found in 36% of patients and 2% of asthmatic. The number of patients experiencing an adverse event is 42 on a total of 107 patients collected either 39.25%. When the children were younger than one year adverse events occurred with 30, 76%. The occurrence of adverse events was more frequent when the child was not intubated with P < 0.05. All adverse events have received support except tachycardia, late revival but all developed positively. This study estimates the incidence of adverse events in anesthesia during pediatric surgery. The overall rate of patients experiencing an adverse event is relatively high. Children age less than or equal to one year are most vulnerable.

Background Clinical trials leading to regulatory approval, or registration trials, play a central role in the development of drugs and medical devices. The contribution of support staff, such as the clinical research coordinator (CRC) and administrative officers, in registration trials is now widely recognized. Attending to serious adverse events is an important duty of the CRC and investigators alike, and managing these complications and compensation constitutes a key responsibility. We retrospectively examined the frequency of serious adverse events and compensation events reported from 2007 through 2011 at Tokushima University Hospital, an academic hospital in rural Japan. We present herein the results of our analysis. Results Over the five-year period, 284 subjects participating in 106 registration trials experienced a total of 43 serious adverse events, and eight compensation events were documented. Among the serious adverse events, 35 (81.4%) were considered not related to the investigational drug, and 17 (39.5%) resulted in withdrawal of the study drug. Patients with malignant diseases experienced serious adverse events significantly more frequently compared to those with non-malignant diseases (28.3% versus 8.2%, respectively; P < 0.01). Conclusions The CRC should be vigilant for serious adverse events in oncology clinical trials due to the generally higher frequency of these complications in subjects with malignancy. However, on an individual basis, the CRC may be seldom involved in the process for compensating serious adverse events. Therefore, the CRC’s ability to share such experiences may serve as an opportunity for educating clinical trial support staff at the study site as well as those at other sites. However, further study is warranted to determine the role of the clinical trial support staff in optimizing methods for managing adverse events requiring compensation in registration trials.

Despite their ubiquitous use and several recent health controversies involving cosmetics and personal care products for children, the Food and Drug Administration has little oversight of these products and relies on consumer-submitted adverse event reports. We assessed the recently released Center for Food Safety and Applied Nutrition's Adverse Event Reporting System database for adverse event reports submitted to the Food and Drug Administration for baby personal care products and to determine whether useful insights can be derived. We extracted the Center for Food Safety and Applied Nutrition's Adverse Event Reporting System data file from 2004 to 2016 and examined the subset classified according to the Food and Drug Administration-designated product class as a baby product. Events were manually categorized into product type and symptom type to assess for trends. Only 166 total adverse events were reported to the Food and Drug Administration for baby products from 2004 to 2016. The majority of reports indicated rash or other skin reaction; 46% of reported events led to a health care visit. Pediatric dermatologists should consider submitting cosmetics and personal care product adverse event reports and encouraging consumers to do so likewise in situations in which a product adversely affects a child's health. © 2018 Wiley Periodicals, Inc.

Taxanes (docetaxel and paclitaxel) are among the most commonly prescribed anticancer drugs approved for the treatment of metastatic or locally advanced breast, non-small cell lung, prostate, gastric, head and neck, and ovarian cancers, as well as in the adjuvant setting for operable node-positive breast cancers. Although the true incidence of dermatological adverse events (AEs) in patients receiving taxanes is not known, and has never been prospectively analysed, they clearly represent one of the major AEs associated with these agents. With an increase in the occurrence of cutaneous AEs during treatment with novel targeted and immunological therapies when used in combination with taxanes, a thorough understanding of reactions attributable to this class is imperative. Moreover, identification and management of dermatological AEs is critical for maintaining the quality of life in cancer patients and for minimizing dose modifications of their antineoplastic regimen. This analysis represents a systematic review of the dermatological conditions reported with the use of these drugs, complemented by experience at comprehensive cancer centres. The conditions reported herein include skin, hair, and nail toxicities. Lastly, we describe the dermatological data available for the new, recently FDA-and EMA- approved, solvent-free nab-paclitaxel.

Use of HIT for adverse event reporting in nursing homes: barriers and facilitators.
Wagner, Laura M; Castle, Nicholas G; Handler, Steven M
2013-01-01
Approximately 8 million adverse events occur annually in nursing homes (NHs). The focus of this research is to determine barriers and health information technology (HIT)-related facilitators to adverse event reporting among U.S. NHs. Surveys were returned by 399 nursing home administrators using a mailed survey approach. Respondents were asked to report on their adverse event reporting processes focusing on barriers and role of HIT facilitators. About 15% of NHs had computerized entry by the nurse on the unit and almost 18% used no computer technology to track, monitor, or maintain adverse event data. One-third of nursing directors conducted data analysis "by-hand." NHs without HIT were more likely to not be accredited (p = 0.04) and not part of a chain/corporation (p = 0.03). Two of the top three barriers focused on fears of reporting as a barrier. This study found numerous barriers and few HIT-related facilitators to assist with adverse event reporting. Improvements in facilitating adverse event reporting through the use of HIT approaches may be warranted. Copyright © 2013 Mosby, Inc. All rights reserved.
Projecting adverse event incidence rates using empirical Bayes methodology.
Ma, Guoguang Julie; Ganju, Jitendra; Huang, Jing
2016-08-01
Although there is considerable interest in adverse events observed in clinical trials, projecting adverse event incidence rates in an extended period can be of interest when the trial duration is limited compared to clinical practice. A naïve method for making projections might involve modeling the observed rates into the future for each adverse event. However, such an approach overlooks the information that can be borrowed across all the adverse event data. We propose a method that weights each projection using a shrinkage factor; the adverse event-specific shrinkage is a probability, based on empirical Bayes methodology, estimated from all the adverse event data, reflecting evidence in support of the null or non-null hypotheses. Also proposed is a technique to estimate the proportion of true nulls, called the common area under the density curves, which is a critical step in arriving at the shrinkage factor. The performance of the method is evaluated by projecting from interim data and then comparing the projected results with observed results. The method is illustrated on two data sets. © The Author(s) 2013.

Despite growing recognition that cumulative adversity (total stressor exposure, including complex trauma), increases the risk for psychopathology and impacts development, assessment strategies lag behind: Adversity-related mental health needs (symptoms, functional impairment, maladaptive coping) are typically assessed in response to only one qualifying Criterion-A traumatic event. This is especially problematic for youth at-risk for health and academic disparities who experience cumulative adversity, including non-qualifying events (separation from caregivers) which may produce more impairing symptomatology. Data from 118 delinquent girls demonstrate: (1) an average of 14 adverse Criterion-A and non-Criterion event exposures; (2) serious maladaptive coping strategies (self-injury) directly in response to cumulative adversity; (3) more cumulative adversity-related than worst-event related symptomatology and functional impairment; and (4) comparable symptomatology, but greater functional impairment, in response to non-Criterion events. These data support the evaluation of mental health needs in response to cumulative adversity for optimal identification and tailoring of services in high-risk populations to reduce disparities.

The aim of the study was to compare the predictions of five popular cardiovascular disease (CVD) risk prediction models, namely the Data Collection on Adverse Events of Anti-HIV Drugs (D:A:D) model, the Framingham Heart Study (FHS) coronary heart disease (FHS-CHD) and general CVD (FHS-CVD) models, the American Heart Association (AHA) atherosclerotic cardiovascular disease risk score (ASCVD) model and the Systematic Coronary Risk Evaluation for the Netherlands (SCORE-NL) model. A cross-sectional design was used to compare the cumulative CVD risk predictions of the models. Furthermore, the predictions of the general CVD models were compared with those of the HIV-specific D:A:D model using three categories (< 10%, 10-20% and > 20%) to categorize the risk and to determine the degree to which patients were categorized similarly or in a higher/lower category. A total of 997 HIV-infected patients were included in the study: 81% were male and they had a median age of 46 [interquartile range (IQR) 40-52] years, a known duration of HIV infection of 6.8 (IQR 3.7-10.9) years, and a median time on ART of 6.4 (IQR 3.0-11.5) years. The D:A:D, ASCVD and SCORE-NL models gave a lower cumulative CVD risk, compared with that of the FHS-CVD and FHS-CHD models. Comparing the general CVD models with the D:A:D model, the FHS-CVD and FHS-CHD models only classified 65% and 79% of patients, respectively, in the same category as did the D:A:D model. However, for the ASCVD and SCORE-NL models, this percentage was 89% and 87%, respectively. Furthermore, FHS-CVD and FHS-CHD attributed a higher CVD risk to 33% and 16% of patients, respectively, while this percentage was < 6% for ASCVD and SCORE-NL. When using FHS-CVD and FHS-CHD, a higher overall CVD risk was attributed to the HIV-infected patients than when using the D:A:D, ASCVD and SCORE-NL models. This could have consequences regarding overtreatment, drug-related adverse events and drug-drug interactions. © 2015 British HIV Association.

Evidence suggests that adverse experiences in childhood are associated with psychosis. To examine the association between childhood adversity and trauma (sexual abuse, physical abuse, emotional/psychological abuse, neglect, parental death, and bullying) and psychosis outcome, MEDLINE, EMBASE, PsychINFO, and Web of Science were searched from January 1980 through November 2011. We included prospective cohort studies, large-scale cross-sectional studies investigating the association between childhood adversity and psychotic symptoms or illness, case-control studies comparing the prevalence of adverse events between psychotic patients and controls using dichotomous or continuous measures, and case-control studies comparing the prevalence of psychotic symptoms between exposed and nonexposed subjects using dichotomous or continuous measures of adversity and psychosis. The analysis included 18 case-control studies (n = 2048 psychotic patients and 1856 nonpsychiatric controls), 10 prospective and quasi-prospective studies (n = 41 803) and 8 population-based cross-sectional studies (n = 35 546). There were significant associations between adversity and psychosis across all research designs, with an overall effect of OR = 2.78 (95% CI = 2.34–3.31). The integration of the case-control studies indicated that patients with psychosis were 2.72 times more likely to have been exposed to childhood adversity than controls (95% CI = 1.90–3.88). The association between childhood adversity and psychosis was also significant in population-based cross-sectional studies (OR = 2.99 [95% CI = 2.12–4.20]) as well as in prospective and quasi-prospective studies (OR = 2.75 [95% CI = 2.17–3.47]). The estimated population attributable risk was 33% (16%–47%). These findings indicate that childhood adversity is strongly associated with increased risk for psychosis. PMID:22461484

The aim of this study was to determine whether elements of transformational leadership are present in nursing managers' actions following adverse events. Transformational leadership exerts a positive influence on organisational culture and patient safety. Eleven nursing managers were interviewed individually using a semi-structured format. Data were analysed using inductive content analysis. Four themes emerged relating to nursing managers' actions following adverse events: patient-centredness as a principle for common action, courage to reform operational models to prevent future adverse events, nursing staff's encouragement of open and blame-free discussion, and challenge to recognize adverse events. Nursing managers must understand their responsibilities and the importance of making it clear to staff that patient-centredness should be evident in all health care actions. Nursing managers must also recognize the need to ensure that staff treat patients' interests as the top priority. If an adverse event occurs, the situation should be discussed with the nursing staff and any unique aspects of the event must be accounted for. Nursing managers must have the skill to motivate and empower staff to find new ways to work, to prevent adverse events and to promote patient safety. © 2017 John Wiley & Sons Ltd.

Recent ecological studies have suggested that inadequate nurse staffing may contribute to the incidence of adverse events in acute care hospitals. However, longitudinal studies are needed to further examine these associations and to identify the staffing patterns that are of greatest risk. The aims of this study are to determine if (a) nurse staffing levels are associated with an increased risk of adverse events, (b) the risk of adverse events in relationship to nurse staffing levels is modified by the complexity of patient requirements, and (c) optimal nurse staffing levels can be established. A dynamic cohort of all adult medical, surgical, and intensive care unit patients admitted between 2010 and 2015 to a Canadian academic health center will be followed during the inpatient and 7-day post-discharge period to assess the occurrence and frequency of adverse events in relationship to antecedent nurse staffing levels. Four potentially preventable adverse events will be measured: (a) hospital-acquired pneumonia, (b) ventilator-associated pneumonia, (c) venous thromboembolism, and (d) in-hospital fall. These events were selected for their high incidence, morbidity and mortality rates, and because they are hypothesized to be related to nurse staffing levels. Adverse events will be ascertained from electronic health record data using validated automated detection algorithms. Patient exposure to nurse staffing will be measured on every shift of the hospitalization using electronic payroll records. To examine the association between nurse staffing levels and the risk of adverse events, four Cox proportional hazards regression models will be used (one for each adverse event), while adjusting for patient characteristics and risk factors of adverse event occurrence. To determine if the association between nurse staffing levels and the occurrence of adverse events is modified by the complexity of patient requirements, interaction terms will be included in the regression models, and their significance assessed. To assess for the presence of optimal nurse staffing levels, flexible nonlinear spline functions will be fitted. This study will likely generate evidence-based information that will assist managers in making the most effective use of scarce nursing resources and in identifying staffing patterns that minimize the risk of adverse events.

An increasing number of people seek medical attention for symptoms of visual discomfort due to computer vision syndrome (CVS). We compared the efficacy and adverse event rates of a new eye lubricant, OptiZen (InnoZen, Inc., polysorbate 80 0.5%) and Visine Original (Pfizer Consumer Healthcare, tetrahydrozoline HCl 0.05%). In this double-blind parallel arm trial, 50 healthy men and women, ages 18 to 65 years, with symptoms of CVS who use a video display terminal for a minimum of 4 hours per day were randomized to OptiZen (n = 25) or Visine Original (n= 25), 1 to 2 drops b.i.d. for 5 days. The primary end-points were ocular discomfort and adverse events. OptiZen and Visine Original had similar efficacy in alleviating symptoms of ocular discomfort (odds ratio of 1.23 [95% confidence interval, 0.63 to 2.42], P= 0.55). OptiZen and Visine Original were very similar with respect to odds ratios and 95% confidence interval (CI) for each of the measurement times (P= 0.72). Visine Original users reported a significantly higher incidence of temporary ocular stinging/burning immediately after drug instillation (28%, 7/25) than did OptiZen users (4%, 1/24) (P= 0.05). Patients using OptiZen were 89% less likely to have stinging/burning effects than those patients using Visine Original (95% CI: 0.01 to 0.95). OptiZen and Visine Original are effective at alleviating ocular discomfort associated with prolonged computer use. Adverse event findings suggest that OptiZen causes less ocular discomfort on instillation, potentially attributable to its milder ingredient profile.

Open-label trials suggest that escitalopram (up to 20 mg/d) is an effective treatment for some, but not all posttraumatic stress disorder (PTSD) patients. Higher doses of escitalopram effectively reduced major depression symptoms in patients who had not responded to regular doses. The current study examines the efficacy, tolerability, and adherence to high-dose escitalopram in PTSD. Forty-five PTSD patients received 12 weeks of gradually increasing doses of escitalopram reaching 40 mg daily at 4 weeks. Among those, 12 participants received regular doses of antidepressants at study onset including escitalopram (n = 7). The Clinician-Administered PTSD Scale (CAPS) evaluated PTSD symptoms severity before treatment, at 3 months (upon treatment termination), and at 6 months (maintenance effect). A 20% reduction in CAPS scores was deemed clinically significant. Adverse events and medication adherence were monitored at each clinical session. Linear mixed-models analysis showed a significant reduction of mean CAPS scores (11.5 ± 18.1 points) at 3 months and maintenance of gains by 6 months (F2,34.56 = 8.15, P = 0.001). Eleven participants (34.3%) showed clinically significant improvement at 3 months. Only 9 participants (20%) left the study. There were no serious adverse events and few mild ones with only 2 adverse events (diarrhea, 11.1%; drowsiness, 11.1%) reported by more than 10% of participants. High doses of escitalopram are tolerable and well adhered to in PTSD. Their beneficial effect at a group level is due to a particularly good response in a subset of patients.Variability in prior pharmacological treatment precludes a definite attribution of the results to high doses of escitalopram.

Background Female patients receiving immunosuppressive therapy may be at increased risk for human papillomavirus (HPV) infection and cervical neoplasia. Methods We administered the 3-dose HPV vaccine Gardasil® to 37 females aged 9-26 years with inflammatory bowel disease (IBD) prescribed immunosuppressive therapy (prospective cohort). Geometric mean titers (GMT) in milli-Merck (mMu/mL) units were determined before dose 1 and one month after dose 3 by competitive Luminex immunoassay (cLIA) and qualitatively compared to healthy females of similar age from Merck’s database. Side effects and adverse events were evaluated. Concurrently, in 15 similar IBD patients previously vaccinated by their primary care provider we assessed antibody titers by cLIA and total IgG LIA after dose 3 of vaccine (range 0.5 to 27 months). Results The mean age of prospective patients was 15 years with 51% on anti-TNF therapy and 49% on immunomodulators: 33 of 37 completed all three doses. Seropositivity after dose 3 was 100% for types 6, 11 and 16 and 96% for type 18. GMT for HPV 6, 11, 16 and 18 was 1080, 1682, 3975 and 858, respectively, and did not qualitatively differ from healthy females. No serious adverse events were attributable to the vaccine. In the previously vaccinated cohort, seropositivity was 100% for types 6, 11, and 16, and 40% for type 18 by cLIA (93% for HPV18 by IgG LIA). Titers decreased with time since dose 3. Conclusions In this small study of IBD patients prescribed immunosuppressive therapy, Gardasil® was immunogenic and there were no clinically significant vaccine-associated adverse events.

Transcranial Magnetic Stimulation (TMS) customarily uses high-field electromagnets to achieve therapeutic efficacy in Major Depressive Disorder (MDD). Low-field magnetic stimulation also may be useful for treatment of MDD, with fewer treatment-emergent adverse events. To examine efficacy, safety, and tolerability of low-field magnetic stimulation synchronized to an individual's alpha frequency (IAF) (synchronized TMS, or sTMS) for treatment of MDD. Six-week double-blind sham-controlled treatment trial of a novel device that used three rotating neodymium magnets to deliver sTMS treatment. IAF was determined from a single-channel EEG prior to first treatment. Subjects had baseline 17-item Hamilton Depression Rating Scale (HamD17) ≥ 17. 202 subjects comprised the intent-to-treat (ITT) sample, and 120 subjects completed treatment per-protocol (PP). There was no difference in efficacy between active and sham in the ITT sample. Subjects in the PP sample (N = 59), however, had significantly greater mean decrease in HamD17 than sham (N = 60) (-9.00 vs. -6.56, P = 0.033). PP subjects with a history of poor response or intolerance to medication showed greater improvement with sTMS than did treatment-naïve subjects (-8.58 vs. -4.25, P = 0.017). Efficacy in the PP sample reflects exclusion of subjects who received fewer than 80% of scheduled treatments or were inadvertently treated at the incorrect IAF; these subgroups failed to separate from sham. There was no difference in adverse events between sTMS and sham, and no serious adverse events attributable to sTMS. Results suggest that sTMS may be effective, safe, and well tolerated for treating MDD when administered as intended. Copyright © 2015 Elsevier Inc. All rights reserved.

Obesity is associated with greater rates of surgical complications. To address these complications after outpatient plastic surgery, obese patients may seek care in the emergency department and potentially require admission to the hospital, which could result in greater health care charges. The purpose of this study was to determine the relationship of obesity, postdischarge hospital-based acute care, and hospital charges within 30 days of outpatient plastic surgery. From state ambulatory surgery center databases in four states, all discharges for adult patients who underwent liposuction, abdominoplasty, breast reduction, and blepharoplasty were identified. Patients were grouped by the presence or absence of obesity. Multivariable regression models were used to compare the frequency of hospital-based acute care, serious adverse events, and hospital charges within 30 days between groups while controlling for confounding variables. The final sample included 47,741 discharges, with 2052 of these discharges (4.3 percent) being obese. Obese patients more frequently had a hospital-based acute care encounter [7.3 percent versus 3.9 percent; adjusted OR, 1.35 (95% CI,1.13 to 1.61)] or serious adverse event [3.2 percent versus 0.9 percent; adjusted OR, 1.73 (95% CI, 1.30 to 2.29)] within 30 days of surgery. Obese patients had adjusted hospital charges that were, on average, $3917, $7412, and $7059 greater (p < 0.01) than those of nonobese patients after liposuction, abdominoplasty, and breast reduction, respectively. Obese patients who undergo common outpatient plastic surgery procedures incur substantially greater health care charges, in part attributable to more frequent adverse events and hospital-based health care within 30 days of surgery.

Percutaneous closure of patent ductus arteriosus (PDA) in term neonates is established, but data regarding outcomes in infants born very preterm (<32 weeks of gestation) are minimal, and no published criteria exist establishing a minimal weight of 4 kg as a suitable cutoff. We sought to analyze outcomes of percutaneous PDA occlusion in infants born very preterm and referred for PDA closure at weights <4 kg. Retrospective analysis (January 2005-January 2014) was done at a single pediatric center. Procedural successes and adverse events were recorded. Markers of respiratory status (need for mechanical ventilation) were determined, with comparisons made before and after catheterization. A total of 52 very preterm infants with a median procedural weight of 2.9 kg (range 1.2-3.9 kg) underwent attempted PDA closure. Twenty-five percent (13/52) of infants were <2.5 kg. Successful device placement was achieved in 46/52 (88%) of infants. An adverse event occurred in 33% of cases, with an acute arterial injury the most common complication. We observed no association between weight at time of procedure and the risk of an adverse event. No deaths were attributable to the PDA closure. Compared to precatheterization trends, percutaneous PDA closure resulted in improved respiratory status, including less exposure to mechanical ventilation (mixed effects logistic model, P<0.01). Among infants born very preterm, percutaneous PDA closure at weights <4 kg is generally safe and may improve respiratory health, but risk of arterial injury is noteworthy. Randomized clinical trials are needed to assess clinically relevant differences in outcomes following percutaneous PDA closure versus alternative (surgical ligation) management strategies. © 2016 The Authors.

Can the frequency and risks of fatal adverse drug events be determined?
Kelly, W N
2001-05-01
Death is the ultimate adverse drug event. Despite its importance, the frequency of fatal adverse drug events is unknown. Estimates in the United States are as high as 140,000/year, although this number is heavily disputed. Potential reasons and risks for fatal adverse drug events, as well as epidemiologic designs for studying this important public health issue, are discussed and issues are raised to promote further thought.
Orthopaedic Snafus: When Adverse Events Happen in Orthopaedics.
Smith, Mary Atkinson; Walsh, Colleen; Levin, Barbara; Eaten, Kathyrn; Yager, Melissa
The potential for adverse events exists when treating and managing orthopaedic patients in the intraoperative or postoperative environments, especially when it comes to falls, surgical site infections, venous thromboembolism, and injuries to nerves and blood vessels. Orthopaedic nurses play a vital role in the promotion and use of evidence-based interventions to decrease the incidence of these adverse events, improve quality of care, and minimize the financial burden related to these adverse events.

Little is known of the incidence of adverse events in the paediatric intensive care unit (PICU). Perceived incidence may be dependent on data-collection methods. To determine the incidence of adverse events by voluntary reporting and systematic enquiry. Adverse events in PICU were recorded contemporaneously by systematic enquiry with bedside nurses and attending doctors, and compared with data submitted voluntarily to the hospital's quality and safety unit. Events were classified as insignificant, minor, moderate, major and catastrophic or lethal, and assigned origins as medical/surgical diagnosis or management, medical/surgical procedures, medication or miscellaneous. Among 740 patients, 524 adverse events (mean 0.71 per patient) occurred in 193 patients (26.1%). Systematic enquiry detected 405 (80%) among 165 patients and were classified by one investigator as insignificant 30 (7%); minor 100 (25%); moderate 160 (37%); major 103(25%) and catastrophic 12 (3%). The coefficient of agreement (kappa) of severity between the two investigators was 0.82 (95% CI 0.78-0.87). Voluntary reporting detected 166 (32%) adverse events among 100 patients, of which 119 were undetected by systematic reporting. Forty-nine events (9%) were detected by both methods. The number and severity of events reported by the two methods were significantly different (p<0.0001). Voluntary reporting, mainly by nurses, did not capture major, severe or catastrophic events related to medical/surgical diagnosis or management. Neither voluntary reporting nor systematic enquiry captures all adverse events. While the two methods both capture some events, systematic reporting captures serious events, while voluntary reporting captures mainly insignificant and minor events.

PURPOSE We aimed to compare clinical outcomes and early adverse events of operative management (OM), nonoperative management (NOM), and NOM with splenic artery embolization (SAE) in blunt splenic injury (BSI) and identify the prognostic factors. METHODS Medical records of 136 consecutive patients with BSI admitted to a trauma center from 2005 to 2010 were retrospectively reviewed. Patients were separated into three groups: OM, NOM, and SAE. We focused on associated injuries and early adverse events. Multivariate analysis was performed on 23 prognostic factors to find predictors. RESULTS The total survival rate was 97.1%, with four deaths all occurred in the OM group. The spleen salvage rate was 91% in NOM and SAE. At least one adverse event was observed in 32.8%, 62%, and 96% of patients in NOM, SAE, and OM groups, respectively (P < 0.001). We found significantly more deaths, infectious complications, pleural drainage, acute renal failures, and pancreatitis in OM and more pseudocysts in SAE. Six prognostic factors were statistically significant for one or more adverse events: simplified acute physiology score 2 ≥25 for almost all adverse events, age ≥50 years for acute respiratory syndrome, limb fracture for secondary bleeding, thoracic injury for pleural drainage, and at least one associated injury for pseudocyst. Adverse events were not related to the type of BSI management. CONCLUSION Patients with BSI present worse outcome and more adverse events in OM, but this is related to the severity of injury. The main predictor of adverse events remains the severity of injury. PMID:26081719

Preterm and former preterm children frequently require sedation/anesthesia for diagnostic and therapeutic procedures. Our objective was to determine the age at which children who are born <37 weeks gestational age are no longer at increased risk for sedation/anesthesia adverse events. Our secondary objective was to describe the nature and incidence of adverse events. This is a prospective observational study of children receiving sedation/anesthesia for diagnostic and/or therapeutic procedures outside of the operating room by the Pediatric Sedation Research Consortium. A total of 57,227 patients 0 to 22 years of age were eligible for this study. All adverse events and descriptive terms were predefined. Logistic regression and locally weighted scatterplot regression were used for analysis. Preterm and former preterm children had higher adverse event rates (14.7% vs 8.5%) compared with children born at term. Our analysis revealed a biphasic pattern for the development of adverse sedation/anesthesia events. Airway and respiratory adverse events were most commonly reported. MRI scans were the most commonly performed procedures in both categories of patients. Patients born preterm are nearly twice as likely to develop sedation/anesthesia adverse events, and this risk continues up to 23 years of age. We recommend obtaining birth history during the formulation of an anesthetic/sedation plan, with heightened awareness that preterm and former preterm children may be at increased risk. Further prospective studies focusing on the etiology and prevention of adverse events in former preterm patients are warranted. Copyright © 2016 by the American Academy of Pediatrics.

It is not clear whether adherence to preprocedural fasting guidelines prevent pulmonary aspiration and associated adverse outcomes during emergency department (ED) sedation of children. To examine the association between preprocedural fasting duration and the incidence of sedation-related adverse outcomes in a large sample of children. We conducted a planned secondary analysis of a multicenter prospective cohort study of children aged 0 to 18 years who received procedural sedation for a painful procedure in 6 Canadian pediatric EDs from July 2010 to February 2015. The primary risk factor was preprocedural fasting duration. Secondary risk factors were age, sex, American Society of Anesthesiologists classification, preprocedural and sedation medications, and procedure type. Four outcomes were examined: (1) pulmonary aspiration, (2) the occurrence of any adverse event, (3) serious adverse events, and (4) vomiting. A total of 6183 children with a median age of 8.0 years (interquartile range, 4.0-12.0 years), of whom 6166 (99.7%) had healthy or mild systemic disease (American Society of Anesthesiologists levels I or II), were included in the analysis. Of these, 2974 (48.1%) and 310 (5.0%) children did not meet American Society of Anesthesiologists fasting guidelines for solids and liquids, respectively. There were no cases of pulmonary aspiration. There were 717 adverse events (11.6%; 95% CI, 10.8%-12.4%), of which 68 (1.1%; 95% CI, 0.9%-1.3%) were serious adverse events and 315 (5.1%; 95% CI, 4.6%-5.7%) were vomiting. The odds ratio (OR) of occurrence of any adverse event, serious adverse events, and vomiting did not change significantly with each additional hour of fasting duration for both solids (any adverse event: OR, 1.00; 95% CI, 0.98 to 1.02; serious adverse events, OR, 1.01; 95% CI, 0.95-1.07; vomiting: OR, 1.00; 95% CI, 0.97-1.03) and liquids (any adverse event: OR, 1.00; 95% CI, 0.98-1.02; serious adverse events: 1.01, 95% CI, 0.95-1.07; vomiting: OR, 1.00; 95% CI, 0.96-1.03). In this study, there was no association between fasting duration and any type of adverse event. These findings do not support delaying sedation to meet established fasting guidelines.

The Food and Drug Administration (FDA)'s Center for Food Safety and Applied Nutrition (CFSAN) oversees the safety of the nation's foods, dietary supplements, and cosmetic products. To present a descriptive analysis of the 2004-2013 dietary supplement adverse event report (AER) data from CAERS and evaluate the 2006 Dietary Supplements and Nonprescription Drug Consumer Protection Act as pertaining to dietary supplements adverse events reporting. We queried CAERS for data from the 2004-2013 AERs specifying at least 1 suspected dietary supplement product. We extracted the product name(s), the symptom(s) reported, age, sex, and serious adverse event outcomes. We examined time trends for mandatory and voluntary reporting and performed analysis using SAS v9.4 and R v3.3.0 software. Of the total AERs (n = 15 430) received from January 1, 2004, through December 31, 2013, indicating at least 1 suspected dietary supplement product, 66.9% were mandatory, 32.2% were voluntary, and 0.9% were both mandatory and voluntary. Reported serious outcomes included death, life-threatening conditions, hospitalizations, congenital anomalies/birth defects and events requiring interventions to prevent permanent impairments (5.1%). The dietary supplement adverse event reporting rate in the United States was estimated at ~2% based on CAERS data. This study characterizes CAERS dietary supplement adverse event data for the 2004-2013 period and estimates a reporting rate of 2% for dietary supplement adverse events based on CAERS data. The findings show that the 2006 Dietary Supplements and Nonprescription Drug Consumer Protection Act had a substantial impact on the reporting of adverse events.

OBJECTIVE To estimate the frequency of and to characterize the adverse drug events at a terciary care hospital. METHODS A retrospective review was carried out of 128 medical records from a hospital in Rio de Janeiro in 2007, representing 2,092 patients. The instrument used was a list of triggers, such as antidotes, abnormal laboratory analysis results and sudden suspension of treatment, among others. A simple random sample of patients aged 15 and over was extracted. Oncologic and obstetric patients were excluded as were those hospitalized for less than 48 hours or in the emergency room. Social and demographic characteristics and those of the disease of patients who underwent adverse events were compared with those of patients who did not in order to test for differences between the groups. RESULTS Around 70.0% of the medical records assessed showed at least one trigger. Adverse drug events triggers had an overall positive predictive value of 14.4%. The incidence of adverse drug events was 26.6 per 100 patients and 15.6% patients suffered one or more event. The median length of stay for patients suffering an adverse drug event was 35.2 days as against 10.7 days for those who did not (p < 0.01). The pharmacological classes most commonly associated with an adverse drug event were related to the cardiovascular system, nervous system and alimentary tract and metabolism. The most common active substances associated with an adverse drug event were tramadol, dypirone, glibenclamide and furosemide. Over 80.0% of events provoked or contributed to temporary harm to the patient and required intervention and 6.0% may have contributed to the death of the patient. It was estimated that in the hospital, 131 events involving drowsiness or fainting 33 involving falls, and 33 episodes of hemorrhage related to adverse drug effects occur annually. CONCLUSIONS Almost one-sixth of in-patients (16,0%) suffered an adverse drug event. The instrument used may prove useful as a technique for monitoring and evaluating patient care results. Psycothropic therapy should be critically appraised given the frequency of associated events, such as excessive sedation, lethargy, and hypotension. PMID:24626548

Recently, it has been reported that patients administered with bisphosphonates (BP), in particular cancer patients receiving intravenous amino-bisphosphonates, as well as patients taking oral BP for prevention/treatment of diseases of altered bone turnover, may be affected by a significant adverse reaction-BP-related osteonecrosis of the jaws (BRONJ). This condition may cause high morbidity and detriment of quality of life. Its treatment is complex and often unsatisfactory, and prevention strategies may have limited effectiveness, if any; thus, BRONJ may become a source of litigation in the near future. Although most cases seem to be triggered by invasive dental procedures and oral health care providers are more exposed to malpractice claims and legal actions pursuant to BRONJ, the attribution of liability requires caution. In fact, types of possible negligence claims against oral health care providers have already been highlighted. However, according to the medico-legal methodology, since BRONJ is an adverse reaction to BP administration, the attribution of liability, if any, requires a comprehensive consideration of the chain of events and figures acting before, and potentially related to BRONJ. The physician prescribing BP at the start of this chain has specific duties which we are going to address, and breaching these duties may set the stage for potential liability claims.

Patients initiated on highly active antiretroviral therapy (HAART) generally remain on medication indefinitely. A modification in the HAART regimen may become necessary because of possible acute or chronic toxicities, concomitant clinical conditions, development of virological failure or the advent of adverse drug events. The study documents adverse drug events of HIV-positive Ghanaian patients with HAART modifications. It also investigates the association between documented adverse drug events and HAART modification using an unmatched case-control study design. The study was conducted in the Fevers Unit of the Korle Bu Teaching Hospital and involved patients who attended the HIV Care Clinic between January 2004 and December 2009. Data from 298 modified therapy patients (cases) were compared with 298 continuing therapy patients (controls) who had been on treatment for at least 1 month before the end of study. Controls were sampled from the same database of a cohort of HIV-positive patients on HAART, at the time a case occurred, in terms of treatment initiation ±1 month. Data were obtained from patients' clinical folders and the HIV clinic database linked to the pharmacy database. The nature of the documented adverse drug events of the cases was described and the association between the documented adverse drug events and HAART modification was determined by logistic regression with reported odds ratios (ORs) and their 95 % confidence interval (CI). Among the 298 modified therapy patients sampled in this study, 52.7 % of them had at least one documented adverse drug event. The most documented adverse drug event was anaemia, recorded in 18.5 % of modified therapy patients, all of whom were on a zidovudine-based regimen. The presence of documented adverse drug events was significantly associated with HAART modification [adjusted OR = 2.71 (95 % CI 2.11-3.48), p < 0.001]. Among HIV patients on HAART, adverse drug events play a major role in treatment modification. Occurrence of adverse drug events may be used as a predictor for possible therapy modification. We recommend the institution of active pharmacovigilance in HIV treatment programmes as it permits the proper identification and characterisation of drug-related adverse events. This can help develop approaches towards their management and also justify therapy modifications.
Joint Attributes and Event Analysis for Multimedia Event Detection.
Ma, Zhigang; Chang, Xiaojun; Xu, Zhongwen; Sebe, Nicu; Hauptmann, Alexander G
2017-06-15
Semantic attributes have been increasingly used the past few years for multimedia event detection (MED) with promising results. The motivation is that multimedia events generally consist of lower level components such as objects, scenes, and actions. By characterizing multimedia event videos with semantic attributes, one could exploit more informative cues for improved detection results. Much existing work obtains semantic attributes from images, which may be suboptimal for video analysis since these image-inferred attributes do not carry dynamic information that is essential for videos. To address this issue, we propose to learn semantic attributes from external videos using their semantic labels. We name them video attributes in this paper. In contrast with multimedia event videos, these external videos depict lower level contents such as objects, scenes, and actions. To harness video attributes, we propose an algorithm established on a correlation vector that correlates them to a target event. Consequently, we could incorporate video attributes latently as extra information into the event detector learnt from multimedia event videos in a joint framework. To validate our method, we perform experiments on the real-world large-scale TRECVID MED 2013 and 2014 data sets and compare our method with several state-of-the-art algorithms. The experiments show that our method is advantageous for MED.

Dermatologic adverse events to cancer therapies have become more prevalent and may to lead to dose modifications or discontinuation of life-saving or prolonging treatments. This has resulted in a new collaboration between oncologists and dermatologists, which requires accurate cataloging and grading of side effects. The Common Terminology Criteria for Adverse Events Version 4.0 is a descriptive terminology and grading system that can be used for uniform reporting of adverse events. A proper understanding of this standardized classification system is essential for dermatologists to properly communicate with all physicians caring for patients with cancer.

Male circumcision reduces the risk for female-to-male human immunodeficiency virus (HIV) transmission by approximately 60% (1) and has become a key component of global HIV prevention programs in countries in Eastern and Southern Africa where HIV prevalence is high and circumcision coverage is low. Through September 2017, the President's Emergency Plan for AIDS Relief (PEPFAR) had supported 15.2 million voluntary medical male circumcisions (VMMCs) in 14 priority countries in Eastern and Southern Africa (2). Like any surgical intervention, VMMC carries a risk for complications or adverse events. Adverse events during circumcision of males aged ≥10 years occur in 0.5% to 8% of procedures, though the majority of adverse events are mild (3,4). To monitor safety and service quality, PEPFAR tracks and reports qualifying notifiable adverse events. Data reported from eight country VMMC programs during 2015-2016 revealed that bleeding resulting in hospitalization for ≥3 days was the most commonly reported qualifying adverse event. In several cases, the bleeding adverse event revealed a previously undiagnosed or undisclosed bleeding disorder. Bleeding adverse events in men with potential bleeding disorders are serious and can be fatal. Strategies to improve precircumcision screening and performance of circumcisions on clients at risk in settings where blood products are available are recommended to reduce the occurrence of these adverse events or mitigate their effects (5).

Dextromethorphan is the most common over-the-counter (OTC) antitussive medication. We sought to characterize adverse events associated with dextromethorphan in children <12 years old from a surveillance program of OTC cough/cold medication exposures. This is a retrospective case series of oral exposures to dextromethorphan with ≥1 adverse event from multiple U.S. sources (National Poison Data System, FDA Adverse Event Reporting System, manufacturer safety reports, news/media, medical literature) reported between 2008 and 2014. An expert panel determined the relationship between exposure and adverse events, estimated dose ingested, intent of exposure, and identified contributing factors to exposure. 1716 cases contained ≥1 adverse event deemed at least potentially related to dextromethorphan; 1417 were single product exposures. 773/1417 (55%) involved only one single-ingredient dextromethorphan product (dextromethorphan-only). Among dextromethorphan-only cases, 3% followed ingestion of a therapeutic dose; 78% followed an overdose. 69% involved unsupervised self-administration and 60% occurred in children <4 years old. No deaths or pathologic dysrhythmias occurred. Central nervous system [e.g., ataxia (N = 420)] and autonomic symptoms [e.g., tachycardia (N = 224)] were the most common adverse events. Flushing and/or urticarial rash occurred in 18.1% of patients. Dystonia occurred in 5.4%. No fatalities were identified in this multifaceted surveillance program following a dextromethorphan-only ingestion. Adverse events were predominantly associated with overdose, most commonly affecting the central nervous and autonomic systems.

Suicidal behavior in young people is a significant public health problem. However, it is not yet clear whether adversities (adverse life events) may be related to suicidality in adolescence and early adulthood. This paper aimed to investigate systematically the association between the type/number of adverse life events and experiences and suicidal behavior in young people. We developed a detailed strategy to search relevant articles in Pubmed, Scopus, PsycInfo, and Science Direct (January 1980-January 2015) about adverse life events and suicidal behavior. Adverse life events and experiences included maltreatment and violence, loss events, intra-familial problems, school and interpersonal problems. Studies were restricted to suicidal behavior in young people aged 10-25 years. The search yielded 245 articles, of which 28 met our inclusion criteria. Most studies reported a strong association between adversities and suicidality (both suicidal ideation and attempts). Based on the main results, the number of adversities or negative life events experienced seemed to have a positive dose-response relationship with youth suicidal behavior. However, the type of event experienced also appeared to matter: one of the most consistent findings was the association between suicidal behavior and experience of sexual abuse. More prospective studies are needed to elucidate the relative importance of risk accumulation and risk specificity for youth suicide.

We compared the economic impacts of linezolid and vancomycin for the treatment of hospitalized patients with methicillin-resistant Staphylococcus aureus (MRSA)-confirmed nosocomial pneumonia. We used a 4-week decision tree model incorporating published data and expert opinion on clinical parameters, resource use and costs (in 2012 US dollars), such as efficacy, mortality, serious adverse events, treatment duration and length of hospital stay. The results presented are from a US payer perspective. The base case first-line treatment duration for patients with MRSA-confirmed nosocomial pneumonia was 10 days. Clinical treatment success (used for the cost-effectiveness ratio) and failure due to lack of efficacy, serious adverse events or mortality were possible clinical outcomes that could impact costs. Cost of treatment and incremental cost-effectiveness per successfully treated patient were calculated for linezolid versus vancomycin. Univariate (one-way) and probabilistic sensitivity analyses were conducted. The model allowed us to calculate the total base case inpatient costs as $46,168 (linezolid) and $46,992 (vancomycin). The incremental cost-effectiveness ratio favored linezolid (versus vancomycin), with lower costs ($824 less) and greater efficacy (+2.7% absolute difference in the proportion of patients successfully treated for MRSA nosocomial pneumonia). Approximately 80% of the total treatment costs were attributed to hospital stay (primarily in the intensive care unit). The results of our probabilistic sensitivity analysis indicated that linezolid is the cost-effective alternative under varying willingness to pay thresholds. These model results show that linezolid has a favorable incremental cost-effectiveness ratio compared to vancomycin for MRSA-confirmed nosocomial pneumonia, largely attributable to the higher clinical trial response rate of patients treated with linezolid. The higher drug acquisition cost of linezolid was offset by lower treatment failure-related costs and fewer days of hospitalization.

The purpose of the present study was to investigate the traceability of adverse events (AEs) for branded and generic drugs with identical nonproprietary names and to consider potential implications for the traceability of AEs for branded and biosimilar biologics. Adverse event reports in the Food and Drug Administration AE Reporting System (FAERS) were compared with those in a commercial insurance claims database (Truven Health MarketScan(®)) for 2 drugs (levetiracetam and enoxaparin sodium) with manufacturing or prescribing considerations potentially analogous to those of some biosimilars. Monthly rates of branded- and generic-attributed AEs were estimated pre- and post-generic entry. Post-entry branded-to-generic AE relative rate ratios were calculated. In FAERS, monthly AE rate ratios during the post-generic period showed a pattern in which AE rates for the branded products were greater than for the generic products. Differences in rates of brand- and generic-attributed AEs were statistically significant for both study drugs; the AE rate for the branded products peaked at approximately 10 times that of the generic levetiracetam products and approximately 4 times that of the generic enoxaparin sodium products. In contrast, monthly ratios for the MarketScan data were relatively constant over time. Use of the same nonproprietary name for generic and branded products may contribute to poor traceability of AEs reported in the FAERS database due to the significant misattribution of AEs to branded products (when those AEs were in fact associated with patient use of generic products). To ensure accurate and robust safety surveillance and traceability for biosimilar products in the United States, improved product identification mechanisms, such as related but distinguishable nonproprietary names for biosimilars and reference biologics, should be considered.

Across Europe, methicillin-resistant Staphylococcus aureus (MRSA) is considered to be the primary cause of nosocomial pneumonia (NP). In Germany alone, approximately 14,000 cases of MRSA-associated NP occur annually, which may have a significant impact on health care resource use and associated economic costs. The objective of this study was to investigate the economic impact of linezolid compared with that of vancomycin in the treatment of hospitalized patients with MRSA-confirmed NP in the German health care system. A 4-week decision tree model incorporated published data and expert opinion on clinical parameters, resource use, and costs (2012 euros) was constructed. The base case first-line treatment duration for patients with MRSA-confirmed NP was 10 days. Treatment success (survival), failure due to lack of efficacy, serious adverse events, and mortality were possible outcomes that could impact costs. Alternate scenarios were analyzed, such as varying treatment duration (7 or 14 days) or treatment switch due to a serious adverse event/treatment failure (at day 5 or 10). The model calculated total base case inpatient costs of €15,116 for linezolid and €15,239 for vancomycin. The incremental cost-effectiveness ratio favored linezolid (versus vancomycin), with marginally lower costs (by €123) and greater efficacy (+2.7% absolute difference in the proportion of patients successfully treated for MRSA NP). Approximately 85%-87% of the total treatment costs were attributed to hospital stay (primarily in the intensive care unit). Sensitivity analysis yielded similar results. The model results show that linezolid is a cost-effective alternative to vancomycin for MRSA-confirmed NP, largely attributable to the higher clinical response rate of patients treated with linezolid.

Background Past research provides strong evidence that adverse life events heighten the risk of delinquent behavior among adolescents. Urban informal (slum) settlements in sub-Saharan Africa are marked by extreme adversity. However, the prevalence and consequences of adverse life events as well as protective factors that can mitigate the effects of exposure to these events in slum settlements is largely understudied. We examine two research questions. First, are adverse life events experienced at the individual and household level associated with a higher likelihood of delinquent behavior among adolescents living in two slums in Nairobi, Kenya? Second, are parental monitoring, religiosity, and self-esteem protective against delinquency in a context of high adversity? Methods We used cross-sectional data from 3,064 males and females aged 12–19 years who participated in the Transitions to Adulthood Study. We examined the extent to which a composite index of adverse life events was associated with delinquent behavior (measured using a composite index derived from nine items). We also examined the direct and moderating effects of three protective factors: parental monitoring, religiosity, and self-esteem. Results Fifty-four percent of adolescents reported at least one adverse life event, while 18% reported three or more adverse events. For both males and females, adversity was positively and significantly associated with delinquency in bivariate and multivariate models. Negative associations were observed between the protective factors and delinquency. Significant adverse events × protective factor interaction terms were observed for parental monitoring (females and males), religiosity (males), and self-esteem (females). Conclusions Similar to research in high income countries, adverse life events are associated with an increased likelihood of delinquent behavior among adolescents living in urban slums in Kenya, a low-income country. However, parental monitoring, religiosity, and self-esteem may moderate the effect of adversity on delinquent behavior and pinpoint possible avenues to develop interventions to reduce delinquency in resource-poor settings in low and middle income countries.

Oral acetylcysteine (also known as N-acetylcysteine) is used with pirfenidone to treat idiopathic pulmonary fibrosis (IPF) in Europe. However, no randomised studies have investigated the safety and tolerability of this combination. The PANORAMA study assessed the safety and tolerability of acetylcysteine combined with pirfenidone in patients with IPF. Exploratory efficacy endpoints were also assessed. We did a double-blind randomised trial at 48 sites in eight countries. Patients with IPF aged 40-80 years and established on pirfenidone (at least 1602 mg/day for 8 weeks or longer) were randomly assigned in a 1:1 ratio by interactive voice response system to receive concomitant oral acetylcysteine (600 mg, three times daily) or placebo for 24 weeks. A stratified blocked randomisation scheme was used with a block size of 4. Randomisation was stratified by dose of pirfenidone (2403 mg/day [the maximum dose] or <2403 mg/day). Patients, physicians, study staff and the sponsor were masked to treatment group allocation. The primary endpoint was assessment of adverse events, which were collected at each visit and for 28 days after the last dose of study drug. Exploratory efficacy measurements included forced vital capacity (FVC), carbon monoxide diffusing capacity, and 6 min walk distance. Analyses were done in the modified intention-to-treat population, which included all patients who were randomised and received at least one dose of study medication. This study is registered with the European Clinical Trials Database (EudraCT number 2012-000564-14) and has been completed. 123 patients participated in the study between June 28, 2013, and Feb 24, 2015. 61 were assigned to the acetylcysteine group (60 received study medication and included in analysis) and 62 were assigned to the placebo group (all included in analysis). The occurrence of at least one adverse event (46 [77%] patients receiving acetylcysteine vs 50 [81%] receiving placebo), adverse events related to study treatment (17 [28%] vs 16 [26%]), and the number of patients experiencing severe adverse events (three [5%] vs two [3%]), life-threatening adverse events (one [2%] vs one [2%]), or death (one [2%] vs three [5%]) was similar between treatment groups. One case of diarrhoea in the acetylcysteine group was considered severe and related to study treatment. Nine serious adverse events were reported by seven patients: dyspnoea, headache, hypertension, intervertebral disc protrusion, and malignant lung neoplasm in the acetylcysteine group, and aortic aneurysm, contusion, forearm fracture, and worsening IPF in the placebo group. The most common adverse events were cough, nasopharyngitis, and diarrhoea. Photosensitivity occurred more frequently with acetylcysteine (eight [13%] patients) than placebo (one [2%] patient; difference 11·7%; 95% CI 2·6-20·9; p=0·016]), and was not attributable to differences in location, season, or concomitant medication. Four (7%) patients receiving acetylcysteine and three (5%) receiving placebo discontinued study treatment due to adverse events. In the exploratory analysis, change in FVC indicated that clinical benefit from addition of acetylcysteine to pirfenidone is unlikely, with the possibility of a harmful effect in patients with IPF (adjusted rate of decline 125·6 mL/6 months for acetylcysteine vs 34·3 mL/6 months for placebo; difference -91·3 mL; 95% CI -174·4 to -8·3; p=0·031). Findings from the PANORAMA study suggest that addition of acetylcysteine to pirfenidone does not substantially alter the tolerability profile of pirfenidone, and is unlikely to be beneficial in IPF.

As delirium in critically ill children is increasingly recognized, more children are treated with the antipsychotic drug haloperidol, while current dosing guidelines are lacking solid evidence and appear to be associated with a high risk of adverse events. We aim to report on the safety and efficacy of a recently implemented clinical dose-titration protocol with active monitoring of adverse events. From July 2014 until June 2015, when a potential delirium was identified by regular delirium scores and confirmed by a child psychiatrist, haloperidol was prescribed according to the Dutch Pediatric Formulary. Daily, adverse events were systematically assessed, haloperidol plasma concentrations were measured, and delirium symptoms followed. Dependent on the clinical response, plasma concentration, and adverse event, the dose was adjusted. A 28-bed tertiary PICU in the Netherlands. All patients admitted to the PICU diagnosed with delirium. Treatment with haloperidol according to a dose-titration protocol MEASUREMENTS AND MAIN RESULTS:: Thirteen children (median age [range] 8.3 yr [0.4-13.8 yr]) received haloperidol, predominantly IV (median dose [range] 0.027 mg/kg/d [0.005-0.085 mg/kg/d]). In all patients, pediatric delirium resolved, but five of 13 patients developed possible adverse event. These were reversed after biperiden (n = 2), discontinuing (n = 3), and/or lowering the dose (n = 3). Plasma concentrations were all below the presumed therapeutic threshold of 3-12 µg/L. Prospective systematic monitoring of adverse event in critically ill children receiving haloperidol revealed a significant proportion of possible adverse events. Adverse event developed despite low plasma concentrations and recommended dose administration in the majority of the patients. Our data suggest that haloperidol can potentially improve pediatric delirium, but it might also put patients at risk for developing adverse events.

To develop and validate standardized criteria for assessing abortion-related incidents (adverse events, morbidities, near misses) for first-trimester aspiration abortion procedures and to demonstrate the utility of a standardized framework [the Procedural Abortion Incident Reporting & Surveillance (PAIRS) Framework] for estimating serious abortion-related adverse events. As part of a California-based study of early aspiration abortion provision conducted between 2007 and 2013, we developed and validated a standardized framework for defining and monitoring first-trimester (≤14weeks) aspiration abortion morbidity and adverse events using multiple methods: a literature review, framework criteria testing with empirical data, repeated expert reviews and data-based revisions to the framework. The final framework distinguishes incidents resulting from procedural abortion care (adverse events) from morbidity related to pregnancy, the abortion process and other nonabortion related conditions. It further classifies incidents by diagnosis (confirmatory data, etiology, risk factors), management (treatment type and location), timing (immediate or delayed), seriousness (minor or major) and outcome. Empirical validation of the framework using data from 19,673 women receiving aspiration abortions revealed almost an equal proportion of total adverse events (n=205, 1.04%) and total abortion- or pregnancy-related morbidity (n=194, 0.99%). The majority of adverse events were due to retained products of conception (0.37%), failed attempted abortion (0.15%) and postabortion infection (0.17%). Serious or major adverse events were rare (n=11, 0.06%). Distinguishing morbidity diagnoses from adverse events using a standardized, empirically tested framework confirms the very low frequency of serious adverse events related to clinic-based abortion care. The PAIRS Framework provides a useful set of tools to systematically classify and monitor abortion-related incidents for first-trimester aspiration abortion procedures. Standardization will assist healthcare providers, researchers and policymakers to anticipate morbidity and prevent abortion adverse events, improve care metrics and enhance abortion quality.

Conflicting evidence exists on the efficacy and safety of bivalirudin administered as part of percutaneous coronary intervention (PCI) in patients with an acute coronary syndrome. We randomly assigned 7213 patients with an acute coronary syndrome for whom PCI was anticipated to receive either bivalirudin or unfractionated heparin. Patients in the bivalirudin group were subsequently randomly assigned to receive or not to receive a post-PCI bivalirudin infusion. Primary outcomes for the comparison between bivalirudin and heparin were the occurrence of major adverse cardiovascular events (a composite of death, myocardial infarction, or stroke) and net adverse clinical events (a composite of major bleeding or a major adverse cardiovascular event). The primary outcome for the comparison of a post-PCI bivalirudin infusion with no post-PCI infusion was a composite of urgent target-vessel revascularization, definite stent thrombosis, or net adverse clinical events. The rate of major adverse cardiovascular events was not significantly lower with bivalirudin than with heparin (10.3% and 10.9%, respectively; relative risk, 0.94; 95% confidence interval [CI], 0.81 to 1.09; P=0.44), nor was the rate of net adverse clinical events (11.2% and 12.4%, respectively; relative risk, 0.89; 95% CI, 0.78 to 1.03; P=0.12). Post-PCI bivalirudin infusion, as compared with no infusion, did not significantly decrease the rate of urgent target-vessel revascularization, definite stent thrombosis, or net adverse clinical events (11.0% and 11.9%, respectively; relative risk, 0.91; 95% CI, 0.74 to 1.11; P=0.34). In patients with an acute coronary syndrome, the rates of major adverse cardiovascular events and net adverse clinical events were not significantly lower with bivalirudin than with unfractionated heparin. The rate of the composite of urgent target-vessel revascularization, definite stent thrombosis, or net adverse clinical events was not significantly lower with a post-PCI bivalirudin infusion than with no post-PCI infusion.

Since 1999, the Ministry of Health in Brazil has conducted campaigns of vaccination against influenza targeted towards the elderly, chronically-diseased people and health care workers. The vaccine against influenza is associated with adverse events of minor importance. To investigate the early adverse events related to the vaccine against influenza. CASUISTICS AND METHODS: One hundred and ninety seven elderly individuals and health care workers vaccinated against influenza were included. An inquiry regarding adverse events related to the vaccine was applied seven days after the vaccination. Local adverse events were reported by 32.5% and systemic effects by 26.4% of the vaccinated subjects. Pain in the region of the injection, headache, myalgia, malaise, and coryza were more frequent in the workers than in the elderly (p<0.05). There was no statistically significant difference in the occurrence of fever. The belief of part of the population that credits frequent and uncomfortable adverse events to the vaccine was not confirmed. The subjective adverse events were more frequent in the health care workers, which can influence, in a negative way, the disclosure of the benefits of this vaccine due to their role as opinion makers.

AIM: To assess the safety of bismuth used in Helicobacter pylori (H pylori) eradication therapy regimens. METHODS: We conducted a systematic review and meta-analysis. MEDLINE and EMBASE were searched (up to October 2007) to identify randomised controlled trials comparing bismuth with placebo or no treatment, or bismuth salts in combination with antibiotics as part of eradication therapy with the same dose and duration of antibiotics alone or, in combination, with acid suppression. Total numbers of adverse events were recorded. Data were pooled and expressed as relative risks with 95% confidence intervals (CI). RESULTS: We identified 35 randomised controlled trials containing 4763 patients. There were no serious adverse events occurring with bismuth therapy. There was no statistically significant difference detected in total adverse events with bismuth [relative risk (RR) = 1.01; 95% CI: 0.87-1.16], specific individual adverse events, with the exception of dark stools (RR = 5.06; 95% CI: 1.59-16.12), or adverse events leading to withdrawal of therapy (RR = 0.86; 95% CI: 0.54-1.37). CONCLUSION: Bismuth for the treatment of H pylori is safe and well-tolerated. The only adverse event occurring significantly more commonly was dark stools. PMID:19109870

Adverse drug events are unintended and harmful events related to medications. Adverse drug events are important for patient care, quality improvement, drug safety research, and postmarketing surveillance, but they are vastly underreported. Our objectives were to identify barriers to adverse drug event documentation and factors contributing to underreporting. This qualitative study was conducted in 1 ambulatory center, and the emergency departments and inpatient wards of 3 acute care hospitals in British Columbia between March 2014 and December 2016. We completed workplace observations and focus groups with general practitioners, hospitalists, emergency physicians, and hospital and community pharmacists. We analyzed field notes by coding and iteratively analyzing our data to identify emerging concepts, generate thematic and event summaries, and create workflow diagrams. Clinicians validated emerging concepts by applying them to cases from their clinical practice. We completed 238 hours of observations during which clinicians investigated 65 suspect adverse drug events. The observed events were often complex and diagnosed over time, requiring the input of multiple providers. Providers documented adverse drug events in charts to support continuity of care but never reported them to external agencies. Providers faced time constraints, and reporting would have required duplication of documentation. Existing reporting systems are not suited to capture the complex nature of adverse drug events or adapted to workflow and are simply not used by frontline clinicians. Systems that are integrated into electronic medical records, make use of existing data to avoid duplication of documentation, and generate alerts to improve safety may address the shortcomings of existing systems and generate robust adverse drug event data as a by-product of safer care. ©Corinne M Hohl, Serena S Small, David Peddie, Katherin Badke, Chantelle Bailey, Ellen Balka.

Uveitis is a major extraarticular quality of life-restricting manifestation of juvenile idiopathic arthritis (JIA). The aim of the study is to describe the occurrence of uveitis in JIA patients receiving tumor necrosis factor inhibitors or methotrexate (MTX). Patients' characteristics, treatment, and the reported first occurrence of uveitis as an adverse event were searched in the Biologics in Pediatric Rheumatology Registry. The rates per exposed patients, exposure time, and time until event were calculated. Uveitis was reported as an adverse event in 75 of 3,467 patients; 51 of 2,844 patients were receiving MTX, 37 of 1,700 patients were receiving etanercept, and 13 of 364 patients were receiving adalimumab. Patients with uveitis were younger (mean ± SD age 4.6 ± 4.2 versus 7.4 ± 4.5 years; P < 0.0001), more likely to be antinuclear antibody positive (69% versus 43%; odds ratio [OR] 2.7, P < 0.0001), and had extended oligoarticular JIA (OR 2.2, P = 0.0005). Patients with a uveitis diagnosis before starting treatment more often had a uveitis event (n = 28, 8.4%; OR 8.5, P < 0.0001), and more often received adalimumab (OR 2.15 [95% confidence interval 1.58-2.94], P < 0.0001). In 16 patients, a new uveitis event occurred: 11 while taking MTX (3.2 per 1,000 patient-years), 2 while taking etanercept monotherapy (1.9 per 1,000 patient-years), and 3 while taking etanercept and MTX combination (0.9 per 1,000 patient-years). A new uveitis event occurred early in the disease course after a median disease duration of 1.5 years (interquartile range [IQR] 1.3-3.8) while taking etanercept and 1.8 years (IQR 1.8-2.1) for the MTX cohort. A recurrent uveitis event was reported after a disease duration of 7.6 years (IQR 4.3-10.0) in the etanercept cohort and 4.8 years (IQR 1.0-5.8) in the MTX cohort. Univariate analysis showed that MTX, but not etanercept or adalimumab, led to a lower rate of uveitis. Patients with a history of uveitis had higher risks for uveitis events while taking both etanercept and adalimumab. Methotrexate turned out to be protective. Few patients developed a first uveitis event while taking etanercept, while the rate is comparable to that with MTX. Uveitis may not be attributed to be an adverse drug reaction to etanercept. © 2015, American College of Rheumatology.

Although the reporting of adverse events is a necessary first step in identifying and addressing lapses in patient safety, such events are under-reported, especially by frontline providers such as resident physicians. This study describes and tests relationships between power distance and leader inclusiveness on psychological safety and the willingness of residents to report adverse events. A total of 106 resident physicians from the departments of neurosurgery, orthopaedic surgery, emergency medicine, otolaryngology, neurology, obstetrics and gynaecology, paediatrics and general surgery in a mid-Atlantic teaching hospital were asked to complete a survey on psychological safety, perceived power distance, leader inclusiveness and intention to report adverse events. Perceived power distance (β = -0.26, standard error [SE] 0.06, 95% confidence interval [CI] -0.37 to 0.15; p < 0.001) and leader inclusiveness (β = 0.51; SE 0.07, 95% CI 0.38-0.65; p < 0.001) both significantly predicted psychological safety, which, in turn, significantly predicted intention to report adverse events (β = 0.34; SE 0.08, 95% CI 0.18-0.49; p < 0.001). Psychological safety significantly mediated the direct relationship between power distance and intention to report adverse events (indirect effect: -0.09; SE 0.02, 95% CI -0.13 to 0.04; p < 0.001). Psychological safety also significantly mediated the direct relationship between leader inclusiveness and intention to report adverse events (indirect effect: 0.17; SE 0.02, 95% CI 0.08-0.27; p = 0.001). Psychological safety was found to be a predictor of intention to report adverse events. Perceived power distance and leader inclusiveness both influenced the reporting of adverse events through the concept of psychological safety. Because adverse event reporting is shaped by relationships and culture external to the individual, it should be viewed as an organisational as much as a personal function. Supervisors and other leaders in health care should ensure that policies, procedures and leadership practices build psychological safety and minimise power distance between low- and high-status members in order to support greater reporting of adverse events. © 2016 John Wiley & Sons Ltd.

In the wake of the Patient Safety and Quality Improvement Act of 2005, national attention has increasingly focused on adverse-event reporting as a means of identifying systems changes to improve patient safety. However, physicians and residents have demonstrated meager involvement in this effort. In 2008-2009, the authors measured participation in adverse-event reporting by 680 residents at Oregon Health & Science University before and after implementing a quality improvement initiative, which consisted of a financial incentive and multifaceted educational campaign. The primary measure of success was an increase in the average monthly adverse-event reports submitted by residents to greater than 5% of the institution's overall report submissions. The average number of adverse events reported by residents increased from 1.6% to 9.0% of the institution's overall event reports, representing a 5.6-fold increase during the initiative (P < .001). The relative percentage of resident-submitted reports defined as "near-misses" increased from 6% to 27% during the initiative (P < .001). The novel approach of integrating a retirement benefit and educational campaign to increase residents' involvement in adverse-event reporting was successful. In addition to increasing residents' contributions to adverse-event reporting to levels higher than any documented in the current literature, there was also a remarkable increase in the relative frequency of near-miss reporting by residents.

Background: In the United States, hip fracture rates have declined by 30% coincident with bisphosphonate use. However, bisphosphonates are associated with sporadic cases of atypical femoral fracture. Atypical femoral fractures are usually atraumatic, may be bilateral, are occasionally preceded by prodromal thigh pain, and may have delayed fracture-healing. This study assessed the occurrence of bisphosphonate-associated nonhealing femoral fractures through a review of data from the U.S. FDA (Food and Drug Administration) Adverse Event Reporting System (FAERS) (1996 to 2011), published case reports, and international safety efforts. Methods: We analyzed the FAERS database with use of the proportional reporting ratio (PRR) and empiric Bayesian geometric mean (EBGM) techniques to assess whether a safety signal existed. Additionally, we conducted a systematic literature review (1990 to February 2012). Results: The analysis of the FAERS database indicated a PRR of 4.51 (95% confidence interval [CI], 3.44 to 5.92) for bisphosphonate use and nonhealing femoral fractures. Most cases (n = 317) were attributed to use of alendronate (PRR = 3.32; 95% CI, 2.71 to 4.17). In 2008, international safety agencies issued warnings and required label changes. In 2010, the FDA issued a safety notification, and the American Society for Bone and Mineral Research (ASBMR) issued recommendations about bisphosphonate-associated atypical femoral fractures. Conclusions: Nonhealing femoral fractures are unusual adverse drug reactions associated with bisphosphonate use, as up to 26% of published cases of atypical femoral fractures exhibited delayed healing or nonhealing.

Although numerous studies have focused on the efficacy of deep brain stimulation (DBS) for movement disorders, less is known about surgical adverse events, especially over longer time intervals. Here, we analyze adverse events in 510 consecutive cases from a tertiary movement disorders center at up to 10 years postoperatively. We conducted a retrospective review of adverse events from craniotomies between January 2003 and March 2013. The adverse events were categorized into 2 broad categories--immediate perioperative and time-dependent postoperative events. Across all targets, perioperative mental status change occurred in 18 (3.5%) cases, and symptomatic intracranial hemorrhage occurred in 4 (0.78%) cases. The most common hardware-related event was skin erosion in 13 (2.5%) cases. The most frequent stimulation-related event was speech disturbance in 16 (3.1%) cases. There were no significant differences among surgical targets with respect to the incidence of these events. Time-dependent postoperative events leading to the revision of a given DBS electrode for any reason occurred in 4.7% ± 1.0%, 9.3% ± 1.4%, and 12.4% ± 1.5% of electrodes at 1, 4, and 7 years postoperatively, respectively. Staged bilateral DBS was associated with approximately twice the risk of repeat surgery for electrode replacement vs unilateral surgery (P = .020). These data provide low incidences for adverse events in a large series of DBS surgeries for movement disorders at up to 10 years follow-up. Accurate estimates of adverse events will better inform patients and caregivers about the potential risks and benefits of surgery and provide normative data for process improvement.

Despite growing recognition that cumulative adversity (total stressor exposure), including complex trauma, increases the risk for psychopathology and impacts development, assessment strategies lag behind: Trauma-related mental health needs (symptoms, functional impairment, maladaptive coping) are typically assessed in response to only one qualifying Criterion-A event. This is especially problematic for youth at-risk for health and academic disparities who experience cumulative adversity, including non-qualifying events (parental separations) which may produce more impairing symptomatology. Data from 118 delinquent girls demonstrate: 1) an average of 14 adverse Criterion-A and non-Criterion event exposures; 2) serious maladaptive coping strategies (self-injury) directly in response to cumulative adversity; 3) more cumulative adversity-related than worst-event related symptomatology and functional impairment; and 4) comparable symptomatology, but greater functional impairment, in response to non-Criterion events. These data support the evaluation of mental health needs in response to cumulative adversity for optimal identification and tailoring of services in high-risk populations to reduce disparities.

[Analysis on the adverse events of cupping therapy in the application].
Zhou, Xin; Ruan, Jing-wen; Xing, Bing-feng

The deep analysis has been done on the cases of adverse events and common injury of cupping therapy encountered in recent years in terms of manipulation and patient's constitution. The adverse events of cupping therapy are commonly caused by improper manipulation of medical practitioners, ignoring contraindication and patient's constitution. Clinical practitioners should use cupping therapy cautiously, follow strictly the rules of standard manipulation and medical core system, pay attention to the contraindication and take strict precautions against the occurrence of adverse events.
Post-marketing surveillance of quinolones 1988-1990.
Davey, P G; McDonald, T; Lindsay, G
1991-04-01
It has been much easier to obtain original data on adverse drug reactions (ADR) of quinolones from the pharmaceutical industry than it was two years ago. This is to be welcomed and, as anticipated, the new data continue to suggest that the new 4-quinolones have an ADR profile which is very similar to that of other antimicrobials. Visual disturbance is not a prominent feature, in contrast to the ADR profile of nalidixic acid. Better definition of quinolone ADRs requires prospective study, and the results of a newly completed prescription event monitoring study are awaited with interest. The potential use of computerised databases and record linkage is examined, but at present the number of quinolone prescriptions is too small to assess documentation of serious but rare events such as convulsions. Physicians need to be aware of the limitations of current data on suspected ADRs. Further investment in computerised databases is required to satisfy the requirements for attributing causality of an event to a drug.
Mitigating adverse event reporting bias in spine surgery.

Recent articles in the lay press and literature have raised concerns about the ability to report honest adverse event data from industry-sponsored spine surgery studies. To address this, clinical trials may utilize an independent Clinical Events Committee (CEC) to review adverse events and readjudicate the severity and relatedness accordingly. We are aware of no prior study that has quantified either the degree to which investigator bias is present in adverse event reporting or the effect that an independent CEC has on mitigating this potential bias. The coflex Investigational Device Exemption study is a prospective randomized controlled trial comparing coflex (Paradigm Spine) stabilization with lumbar spinal fusion to treat spinal stenosis and spondylolisthesis. Investigators classified the severity of adverse events (mild, moderate, or severe) and their relationship to the surgery and device (unrelated, unlikely, possibly, probably, or definitely). An independent CEC, composed of three spine surgeons without affiliation to the study sponsor, reviewed and reclassified all adverse event reports submitted by the investigators. The CEC reclassified the level of severity, relation to the surgery, and/or relation to the device in 394 (37.3%) of 1055 reported adverse events. The proportion of adverse events that underwent reclassification was similar in the coflex and fusion groups (37.9% compared with 36.0%, p = 0.56). The CEC was 5.3 (95% confidence interval [CI], 2.6 to 10.7) times more likely to upgrade than downgrade the adverse event. The CEC was 7.3 (95% CI, 5.1 to 10.6) times more likely to upgrade than downgrade the relationship to the surgery and 11.6 (95% CI, 7.5 to 18.8) times more likely to upgrade than downgrade the relationship to the device. The status of the investigator's financial interest in the company had little effect on the reclassification of adverse events. Thirty-seven percent of adverse events were reclassified by the CEC; the large majority of the reclassifications were an upgrade in the level of severity or a designation of greater relatedness to the surgery or device. An independent CEC can identify and mitigate potential inherent investigator bias and facilitate an accurate assessment of the safety profile of an investigational device, and a CEC should be considered a requisite component of future clinical trials.

Monitoring adverse events (AEs) is an important part of clinical research and a crucial target for data standards. The representation of adverse events themselves requires the use of controlled vocabularies with thousands of needed clinical concepts. Several data standards for adverse events currently exist, each with a strong user base. The structure and features of these current adverse event data standards (including terminologies and classifications) are different, so comparisons and evaluations are not straightforward, nor are strategies for their harmonization. Three different data standards - the Medical Dictionary for Regulatory Activities (MedDRA) and the Systematized Nomenclature of Medicine Clinical Terms (SNOMED CT) terminologies, and Common Terminology Criteria for Adverse Events (CTCAE) classification - are explored as candidate representations for AEs. This paper describes the structural features of each coding system, their content and relationship to the Unified Medical Language System (UMLS), and unsettled issues for future interoperability of these standards.

The rate of adverse events during IV conscious sedation.
Schwamburger, Nathan T; Hancock, Raymond H; Chong, Chol H; Hartup, Grant R; Vandewalle, Kraig S
2012-01-01
Conscious sedation has become an integral part of dentistry; it is often used to reduce anxiety or fear in some patients during oral surgery, periodontal surgery, implant placement, and general dentistry procedures. The purpose of this study was to evaluate the frequency of adverse events during IV conscious sedation provided by credentialed general dentists and periodontists in the United States Air Force (USAF). Sedation clinical records (Air Force Form 1417) from calendar year 2009 were requested from all USAF bases. A total of 1,468 records were reviewed and 19 adverse events were noted in 17 patients. IV complication (infiltration) was the most common adverse event. The overall adverse event rate was 1.3 per 100 patients treated. The results of this study show that moderate sedation provided by general dentists and periodontists in the USAF has a low incidence of adverse events, and conscious sedation remains a viable option for providers for the reduction of anxiety in select patients.
Errors, near misses and adverse events in the emergency department: what can patients tell us?
Friedman, Steven M; Provan, David; Moore, Shannon; Hanneman, Kate

We sought to determine whether patients or their families could identify adverse events in the emergency department (ED), to characterize patient reports of errors and to compare patient reports to events recorded by health care providers. This was a prospective cohort study in a quaternary care inner city teaching hospital with approximately 40,000 annual visits. ED patients were recruited for participation in a standardized interview within 24 hours of ED discharge and a follow-up interview 3-7 days after discharge. Responses regarding events were tabulated and compared with physician and nurse notations in the medical record and hospital event reporting system. Of 292 eligible patients, 201 (69%) were interviewed within 24 hours of ED discharge, and 143 (71% of interviewees) underwent a follow-up interview 3-7 days after discharge. Interviewees did not differ from the base ED population in terms of age, sex or language. Analysis of patient interviews identified 10 adverse events (5% incident rate; 95% confidence interval [CI] 2.41%-8.96%), 8 near misses (4% incident rate; 95% CI 1.73%-7.69%) and no medical errors. Of the 10 adverse events, 6 (60%) were characterized as preventable (2 raters; kappa=0.78, standard error [SE] 0.20; 95% CI 0.39-1.00; p=0.01). Adverse events were primarily related to delayed or inadequate analgesia. Only 4 out of 8 (50%) near misses were intercepted by hospital personnel. The secondary interview elicited 2 out of 10 adverse events and 3 out of 8 near misses that had not been identified in the primary interview. No designation (0 out of 10) of an adverse event was recorded in the ED medical record or in the confidential hospital event reporting system. ED patients can identify adverse events affecting their care. Moreover, many of these events are not recorded in the medical record. Engaging patients and their family members in identification of errors may enhance patient safety.

Because neprilysin is involved in the degradation of amyloid-beta, there is concern that the angiotensin-neprilysin inhibitor sacubitril-valsartan could increase the risk for dementia. We analyzed adverse event cases submitted to the Food and Drug Administration Adverse Event Report System from July 2015 to March 2017. Cognition- and dementia-related adverse event cases were defined with the use of broad and narrow structured medical queries. During the period evaluated, 9,004 adverse event reports (out of a total of 2,249,479) involved the use of sacubitril-valsartan. Based on the broad definition, sacubitril-valsartan was associated with cognition- and dementia-related adverse events in 459 reports (5.1%), but this was lower than the proportion of these reports among other medications (6.6%, reporting odds ratio [ROR] 0.72, 95% confidence interval [CI] 0.65-0.79). Restricting the comparison to cases with age >60 years and with the use of a comparator group with heart failure resulted in no association between sacubitril-valsartan and dementia-related adverse events, with the use of both the broad and the narrow definitions (ROR 0.87, 95% CI 0.76-1.02, and ROR 1.06, 95% CI 0.4-3.16, respectively). Sacubitril-valsartan is not associated with a disproportionately high rate of short-term dementia-related adverse effect reports. Long-term studies assessing cognitive outcomes are required to better establish the medication's cognition effects. Copyright © 2018 Elsevier Inc. All rights reserved.

Background Over the past five years, in most hospitals in England and Wales, incident reporting has become well established but it remains unclear how well reports match clinical adverse events. International epidemiological studies of adverse events are based on retrospective, multi‐hospital case record review. In this paper the authors describe the use of incident reporting, pharmacist surveillance and local real‐time record review for the recognition of clinical risks associated with hospital inpatient care. Methodology Data on adverse events were collected prospectively on 288 patients discharged from adult acute medical and surgical units in an NHS district general hospital using incident reports, active surveillance of prescription charts by pharmacists and record review at time of discharge. Results Record review detected 26 adverse events (AEs) and 40 potential adverse events (PAEs) occurring during the index admission. In contrast, in the same patient group, incident reporting detected 11 PAEs and no AEs. Pharmacy surveillance found 10 medication errors all of which were PAEs. There was little overlap in the nature of events detected by the three methods. Conclusion The findings suggest that incident reporting does not provide an adequate assessment of clinical adverse events and that this method needs to be supplemented with other more systematic forms of data collection. Structured record review, carried out by clinicians, provides an important component of an integrated approach to identifying risk in the context of developing a safety and quality improvement programme.

Introduction: The number of malpractice claims against physicians and health institutes is increasing continuously in Israel as in the rest of the Western world, and has become a serious financial burden. Aim: In this study we analyzed the reports of gastroenterologists on endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) adverse events to the risk management authority between January 1, 2000 and December 31, 2006. Methods: All the reported adverse events associated with ERCP and EUS of health institutes and covered by Madanes Insurance Agency were summarized and analyzed. Clinical and epidemiological details about the patients, procedures, and adverse events were coded into an Excel worksheet, discussed, and evaluated. Results: Forty-two cases of ERCP and EUS adverse events were reported. There were nine cases of men (21.4%) and the average age was 69.3 ± 14.3 years. During this period, 10,647 procedures were performed by the institutes concerned and the number of adverse events was 20.2 to 67.8 per year for 10,000 procedures. Perforation occurred in one out of 367 procedures, bleeding in one out of 5323 procedures, teeth trauma in one out of 5323 procedures, and respiratory complications in one out of 10,647 procedures. Conclusion: This is the first study in Israel about physicians’ reports of ERCP and EUS adverse events. Physicians reported only about severe adverse events with high rate of mortality and morbidity.

The purpose was 1) to prospectively determine the prevalence of adverse events necessitating intensive care unit (ICU) monitoring in gallstone pancreatitis (GP) and 2) To identify admission prognostic indicators that predict the need for ICU unit monitoring. Prospective laboratory data, physiologic parameters, and APACHE II scores were gathered on 102 patients with GP over 14 months. Adverse events were defined as cardiac, respiratory, or renal failure, gastrointestinal bleeding, stroke, sepsis, and necrotizing pancreatitis. Patients were divided into Group 1 (no adverse events, n=95) and Group 2 (adverse events, n=7). There were no deaths and 7 (7%) adverse events, including necrotizing pancreatitis (3), cholangitis (2), and cardiac (2). APACHE 11 > or = 5 (P < 0.005), blood urea nitrogen (BUN) > or = 12 mmol/L (P < 0.005), white blood cell count (WBC) > or = 14.5 x 10(9)/L, (P < 0.001), heart rate > or = 100 bpm (P < 0.001), and glucose > or = 150 mg/dL (P < 0.005) were each independent predictors of adverse events. The sensitivity and specificity of these criteria for predicting severe complications requiring ICU care varied from 71 to 86 per cent and 78 to 87 per cent, respectively. The prevalence of adverse events necessitating ICU care in GP patients is low. Glucose, BUN, WBC, heart rate, and APACHE II scores are independent predictors of adverse events necessitating ICU care. Single criteria predicting the need for ICU care on admission are readily available on admission.

In Ireland, funding of joint arthroplasty procedures has moved to a pay-by-results national tariff system. Typically, adverse clinical events are recorded via retrospective chart-abstraction methods by administrative staff. Missed or undocumented events not only affect the quality of patient care but also may unrealistically skew budgetary decisions that impact fiscal viability of the service. Accurate recording confers clinical benefits and financial transparency. The aim of this study was to compare a prospectively implemented adverse events form with the current national retrospective chart-abstraction method in terms of pay-by-results financial implications. An adverse events form adapted from a similar validated model was used to prospectively record complications in 51 patients undergoing total hip or knee arthroplasties. Results were compared with the same cohort using an existing data abstraction method. Both data sets were coded in accordance with current standards for case funding. Overall, 114 events were recorded during the study through prospective charting of adverse events, compared with 15 events documented by customary method (a significant discrepancy). Wound drainage (15.8%) was the most common complication, followed by anemia (7.9%), lower respiratory tract infections (7.9%), and cardiac events (7%). A total of €61,956 ($67,778) in missed funding was calculated as a result. This pilot study demonstrates the ability to improve capture of adverse events through use of a well-designed assessment form. Proper perioperative data handling is a critical aspect of financial subsidies, enabling optimal allocation of funds. Copyright © 2017 Elsevier Inc. All rights reserved.
Adverse Event Reporting: Harnessing Residents to Improve Patient Safety.

Reporting of adverse and near miss events are essential to identify system level targets to improve patient safety. Resident physicians historically report few events despite their role as front-line patient care providers. We sought to evaluate barriers to adverse event reporting in an effort to improve reporting. Our main outcomes were as follows: resident attitudes about event reporting and the frequency of event reporting before and after interventions to address reporting barriers. We surveyed first year residents regarding barriers to adverse event reporting and used this input to construct a fishbone diagram listing barriers to reporting. Barriers were addressed, and resident event reporting was compared before and after efforts were made to reduce obstacles to reporting. First year residents (97%) recognized the importance of submitting event reports; however, the majority (85%) had not submitted an event report in the first 6 months of residency. Only 7% of residents specified that they had not witnessed an adverse event in 6 months, whereas one third had witnessed 10 or more events. The main barriers were as follows: lack of knowledge about how to submit events (38%) and lack of time to submit reports (35%). After improving resident education around event reporting and simplifying the reporting process, resident event reporting increased 230% (68 to 154 annual reports, P = 0.025). We were able to significantly increase resident event reporting by educating residents about adverse events and near misses and addressing the primary barriers to event reporting. Moving forward, we will continue annual resident education about patient safety, focus on improving feedback to residents who submit reports, and empower senior residents to act as role models to junior residents in patient safety initiatives.

The use of administrative data is an affordable alternative to conducting a difficult large-scale medical-record review to estimate the scale of adverse events. We identified adverse events from 2002 to 2013 on the national level in Korea, using International Classification of Diseases, tenth revision (ICD-10) Y codes. We used data from the National Health Insurance Service-National Sample Cohort (NHIS-NSC). We relied on medical treatment databases to extract information on ICD-10 Y codes from each participant in the NHIS-NSC. We classified adverse events in the ICD-10 Y codes into 6 types: those related to drugs, transfusions, and fluids; those related to vaccines and immunoglobulin; those related to surgery and procedures; those related to infections; those related to devices; and others. Over 12 years, a total of 20 817 adverse events were identified using ICD-10 Y codes, and the estimated total adverse event rate was 0.20%. Between 2002 and 2013, the total number of such events increased by 131.3%, from 1366 in 2002 to 3159 in 2013. The total rate increased by 103.9%, from 0.17% in 2002 to 0.35% in 2013. Events related to drugs, transfusions, and fluids were the most common (19 446, 93.4%), followed by those related to surgery and procedures (1209, 5.8%) and those related to vaccines and immunoglobulin (72, 0.3%). Based on a comparison with the results of other studies, the total adverse event rate in this study was significantly underestimated. Improving coding practices for ICD-10 Y codes is necessary to precisely monitor the scale of adverse events in Korea.

Adverse events are unintended patient injuries or complications that arise from health care management resulting in death, disability or prolonged hospital stay. Adverse events that require critical care are a considerable financial burden to the health care system, but also their global impact on patients and society is probably underestimated. The objectives of this systematic review were to synthesize the best available evidence regarding the estimates of the incidence and preventability of adverse events that necessitate intensive care admission, to determine the type and consequences [mortality, length of intensive care unit (ICU) stay and costs] of these adverse events. MEDLINE (from 1966 to present), EMBASE (from 1974 to present) and CENTRAL (version 1-2010) were searched for studies reporting on unplanned admissions on ICUs. Several other sources were searched for additional studies. Only quantitative studies that used chart review for the detection of adverse events requiring intensive care admission were considered for eligibility. For the purposes of this systematic review, ICUs were defined as specialized hospital facilities which provide continuous monitoring and intensive care for acutely ill patients. Studies that were published in the English, Dutch, German, French or Spanish language were eligible for inclusion. Two reviewers independently extracted data and assessed the methodological quality of the included studies. A total of 27 studies were reviewed. Meta-analysis of the data was not appropriate because of methodological and statistical heterogeneity between studies; therefore, results are presented in a descriptive way. The percentage of surgical and medical adverse events that required ICU admission ranged from 1.1% to 37.2%. ICU readmissions varied from 0% to 18.3%. Preventability of the adverse events varied from 17% to 76.5%. Preventable adverse events are further synthesized by type of event. Consequences of the adverse events included a mean length of ICU stay that ranged from 1.5 days to 10.4 days for the patient's first stay in ICU and mortality percentages between 0% and 58%. Adverse events are an important reason for (re)admission to the ICU and a considerable proportion of these are preventable. It was not possible to estimate an overall incidence and preventability rate of these events as we found considerable heterogeneity. To decrease adverse events that necessitate ICU admission, several systems are recommended such as early detection of patients with clinical instability on general wards and the implementation of rapid response teams. Step-down or intermediate care units could be a useful strategy for patients who require monitoring to avoid ICU readmissions. However, the effectiveness of such systems needs to be investigated. © 2011 Blackwell Publishing Ltd.

Background Accurate reporting of adverse events occurring after vaccination is an important component of determining risk-benefit ratios for vaccinations. Controversy has developed over alleged underreporting of adverse events within U.S. military samples. This report examines the accuracy of adverse event rates recently published for headaches, and examines the issue of underreporting of headaches as a function of civilian or military sources and as a function of passive versus active surveillance. Methods A report by Sejvar et al was examined closely for accuracy with respect to the reporting of neurologic adverse events associated with smallpox vaccination in the United States. Rates for headaches were reported by several scholarly sources, in addition to Sejvar et al, permitting a comparison of reporting rates as a function of source and type of surveillance. Results Several major errors or omissions were identified in Sejvar et al. The count of civilian subjects vaccinated and the totals of both civilians and military personnel vaccinated were reported incorrectly by Sejvar et al. Counts of headaches reported in VAERS were lower (n = 95) for Sejvar et al than for Casey et al (n = 111) even though the former allegedly used 665,000 subjects while the latter used fewer than 40,000 subjects, with both using approximately the same civilian sources. Consequently, rates of nearly 20 neurologic adverse events reported by Sejvar et al were also incorrectly calculated. Underreporting of headaches after smallpox vaccination appears to increase for military samples and for passive adverse event reporting systems. Conclusion Until revised or corrected, the rates of neurologic adverse events after smallpox vaccinated reported by Sejvar et al must be deemed invalid. The concept of determining overall rates of adverse events by combining small civilian samples with large military samples appears to be invalid. Reports of headaches as adverse events after smallpox vaccination appear to be have occurred much less frequently using passive surveillance systems and by members of the U.S. military compared to civilians, especially those employed in healthcare occupations. Such concerns impact risk-benefit ratios associated with vaccines and weigh against making vaccinations mandatory, without informed consent, even among military members. Because of the issues raised here, adverse event rates derived solely or primarily from U.S. Department of Defense reporting systems, especially passive surveillance systems, should not be used, given better alternatives, for making public health policy decisions.

Previously reported complications in medial opening wedge (MOW) high tibial osteotomy (HTO) vary considerably in both rate and severity. (1) To determine the rates of adverse events in MOW HTO classified into different grades of severity based on the treatments required and (2) to compare patient-reported outcomes between the different adverse event classifications. Case series; Level of evidence, 4. All patients receiving MOW HTO at a single medical center from 2005 to 2009 were included. Internal fixation was used in all cases, with either a nonlocking (Puddu) or locking (Tomofix) plate. Patients were evaluated at 2, 6, and 12 weeks; 6 and 12 months; and annually thereafter. Types of potential surgical and postoperative adverse events, categorized into 3 classes of severity based on the subsequent treatments, were defined a priori. Medical records and radiographs were then reviewed by an independent observer. The Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores were compared in subgroups of patients based on the categories of adverse events observed. A total of 323 consecutive procedures (242 males) were evaluated (age, mean ± standard deviation, 46 ± 9 years; body mass index, mean ± standard deviation, 30 ± 5 kg/m(2)). Adverse events requiring no additional treatment (class 1) were undisplaced lateral cortical breaches (20%), displaced (>2 mm) lateral hinge fracture (6%), delayed wound healing (6%), undisplaced lateral tibial plateau fracture (3%), hematoma (3%), and increased tibial slope ≥10° (1%). Adverse events requiring additional or extended nonoperative management (class 2) were delayed union (12%), cellulitis (10%), limited hardware failure (1 broken screw; 4%), postoperative stiffness (1%), deep vein thrombosis (1%), and complex regional pain syndrome (CRPS) type 1 (1%). Adverse events requiring additional or revision surgery and/or long-term medical care (class 3) were aseptic nonunion (3%), deep infection (2%), CRPS type 2 (1%), and severe hardware failure with loss of correction (1%). Additional surgery rate was 3%. Class 1 and 2 adverse events did not affect patient-reported outcomes at 6, 12, or 24 months postoperatively. Patients with class 3 adverse events had significantly lower total WOMAC scores at 6 months but not at 12 or 24 months postoperatively. The most common adverse event in MOW HTO requiring extended nonoperative treatment (class 2) is delayed union (12%). The rate of severe adverse events requiring additional surgery and/or long-term medical care (class 3) is low (7%).

Serious adverse events during hospital care are a worldwide reality and threaten the safety of the hospitalised patient. To identify serious adverse events related to healthcare and direct hospital costs in a Teaching Hospital in México. A study was conducted in a 250-bed Teaching Hospital in San Luis Potosi, Mexico. Data were obtained from the Quality and Patient Safety Department based on 2012 incidents report. Every event was reviewed and analysed by an expert team using the "fish bone" tool. The costs were calculated since the event took place until discharge or death of the patient. A total of 34 serious adverse events were identified. The average cost was $117,440.89 Mexican pesos (approx. €7,000). The great majority (82.35%) were largely preventable and related to the process of care. Undergraduate medical staff were involved in 58.82%, and 14.7% of patients had suffered adverse events in other hospitals. Serious adverse events in a Teaching Hospital setting need to be analysed to learn and deploy interventions to prevent and improve patient safety. The direct costs of these events are similar to those reported in developed countries. Copyright © 2015 Academia Mexicana de Cirugía A.C. Published by Masson Doyma México S.A. All rights reserved.

Background: Energy drink consumption has increased dramatically among young Canadians, with anecdotal evidence of adverse health effects. There is a lack of population-based studies to examine the prevalence of adverse events from energy drinks, particularly among young people. The current study sought to assess adverse events from energy drinks among a population-based sample of youth and young adults in Canada. Methods: An online survey was conducted in 2015 with a national sample of youth (aged 12-17 yr) and young adults (aged 18-24 yr) recruited from a consumer panel. Respondents reported prior consumption of energy drinks as well as adverse outcomes, concurrent activities associated with the outcomes and whether medical attention was sought or considered. Adverse events from coffee were also assessed for comparison. Weighted analyses are reported. Results: Of the 2055 respondents, 1516 (73.8%) reported having ever consumed an energy drink, and 1741 (84.7%) reported having ever consumed coffee (unweighted). Overall, 55.4% of respondents who had ever consumed an energy drink reported that they had experienced at least 1 adverse event, including fast heartbeat (24.7%), difficulty sleeping (24.1%), headache (18.3%), nausea/vomiting/diarrhea (5.1%), chest pain (3.6%) and seizures (0.2%); 3.1% had sought or had considered seeking medical help for an adverse event. The prevalence of reported adverse events was significantly greater among energy drink consumers than among coffee consumers (36.0%) (odds ratio [OR] 2.67 [95% confidence interval (CI) 2.01-2.56]), as was the proportion who reported seeking or considering seeking medical help for adverse events (3.1% v. 1.4%) (OR 2.18 [95% CI 1.39-3.41]). Interpretation: More than half of youth and young adults who had consumed energy drinks reported adverse outcomes, some serious enough to warrant seeking medical help. The adverse outcomes were consistent with the physiologic effects of caffeine but were significantly more prevalent than with other sources of caffeine such as coffee, consistent with data from national adverse event databases.

'Systemic Failures' and 'Human Error' in Canadian TSB Aviation Reports Between 1996 and 2002
NASA Technical Reports Server (NTRS)
Holloway, C. M.; Johnson, C. W.
2004-01-01
This paper describes the results of an independent analysis of the primary and contributory causes of aviation accidents in Canada between 1996 and 2003. The purpose of the study was to assess the comparative frequency of a range of causal factors in the reporting of these adverse events. Our results suggest that the majority of these high consequence accidents were attributed to human error. A large number of reports also mentioned wider systemic issues, including the managerial and regulatory context of aviation operations. These issues are more likely to appear as contributory rather than primary causes in this set of accident reports.
Alcoholics' and nonalcoholics' attributions of control of future life events.
Wright, M H; Obitz, F W
1984-03-01
Alcoholic and nonalcoholic subjects rated the degree of control that they and others possess over future life events. Alcoholics attributed less personal control over events to themselves than nonalcoholics did. Alcoholics also attributed less control to themselves than to others, whereas nonalcoholics attributed more control to themselves than to others. These differences prevailed despite the similar socioeconomic and demographic characteristics, recent life experiences and beliefs concerning the general controllability of events of both alcoholics and nonalcoholics. The attributions of alcoholics were consistent with others' notions of self-handicapping. The attributions of nonalcoholics were consistent with control motivation. Alcoholics who attributed less control to themselves than to others more frequently failed to complete treatment than did alcoholics who attributed more control to themselves.
Application of the Beers Criteria to Alternate Level of Care Patients in Hospital Inpatient Units
Slaney, Heather; MacAulay, Stacey; Irvine-Meek, Janice; Murray, Joshua
2015-01-01
Background: The Beers criteria were developed to help in identifying potentially inappropriate medications (PIMs) for elderly patients. These medications are often associated with adverse events and limited effectiveness in older adults. Patients awaiting an alternate level of care (ALC patients) are those who no longer require acute care hospital services and are waiting for placement elsewhere. They are often elderly, have complex medication regimens, and are at high risk of adverse events. At the time of this study no studies had applied the Beers criteria to ALC patients in Canadian hospitals. Objectives: To determine the proportion of ALC patients receiving PIMs and the proportion experiencing selected PIM-related adverse events. Methods: A retrospective chart review of ALC patients 65 years of age or older was performed to identify PIMs and the occurrence of selected adverse events (specifically central nervous system [CNS] events, falls, bradycardia, hypoglycemia, seizures, insomnia, gastrointestinal bleeding, and urinary tract infections). A logistic regression model with a random intercept for each patient was constructed to estimate odds ratios and probabilities of adverse events. Results: Fifty-two ALC patients were included in the study. Of these, 48 (92%) were taking a PIM. Of the 922 adverse events evaluated, 407 (44.1%) were associated with a regularly scheduled PIM. Among patients who were taking regularly scheduled PIMs, there was a significantly increased probability of an adverse CNS event and of a fall (p < 0.001 for both). The most common PIM medication classes were first-generation antihistamines (24 [46%] of the 52 patients), antipsychotics (21 patients [40%]), short-acting benzodiazepines (15 patients [29%]), and nonbenzodiazepine hypnotics (14 patients [27%]). Conclusions: A high proportion of ALC patients were taking PIMs and experienced an adverse event that may have been related to these drugs. These findings suggest that the ALC population might benefit from regular medication review and monitoring to prevent or detect adverse events. PMID:26157183
Within-Hospital Variation in 30-Day Adverse Events: Implications for Measuring Quality.
Burke, Robert E; Glorioso, Thomas; Barón, Anna K; Kaboli, Peter J; Ho, P Michael
Novel measures of hospital quality are needed. Because quality improvement efforts seek to reduce variability in processes and outcomes, hospitals with higher variability in adverse events may be delivering poorer quality care. We sought to evaluate whether within-hospital variability in adverse events after a procedure might function as a quality metric that is correlated with facility-level mortality rates. We analyzed all percutaneous coronary interventions (PCIs) performed in the Veterans Health Administration (VHA) system from 2007 to 2013 to evaluate the correlation between within-hospital variability in 30-day postdischarge adverse events (readmission, emergency department visit, and repeat revascularization), and facility-level mortality rates, after adjustment for patient demographics, comorbidities, PCI indication, and PCI urgency. The study cohort included 47,567 patients at 48 VHA hospitals. The overall 30-day adverse event rate was 22.0% and 1-year mortality rate was 4.9%. The most variable sites had relative changes of 20% in 30-day rates of adverse events period-to-period. However, within-hospital variability in 30-day events was not correlated with 1-year mortality rates (correlation coefficient = .06; p = .66). Thus, measuring within-hospital variability in postdischarge adverse events may not improve identification of low-performing hospitals. Evaluation in other conditions, populations, and in relationship with other quality metrics may reveal stronger correlations with care quality.

Background: Analysing adverse events is an effective patient safety measure. Aim: We show, how clinical nurse specialists have been enabled to analyse adverse events with the „Learning from Defects-Tool“ (LFD-Tool). Method: Our multi-component implementation strategy addressed both, the safety knowledge of clinical nurse specialists and their attitude towards patient safety. The culture of practice development was taken into account. Results: Clinical nurse specialists relate competency building on patient safety due to the application of the LFD-tool. Applying the tool, fosters the reflection of adverse events in care teams. Conclusion: Applying the „Learning from Defects-Tool“ promotes work-based learning. Analysing adverse events with the „Learning from Defects-Tool“ contributes to the safety culture in a hospital.

Spontaneous reports on suspected serious adverse events caused by medicines from manufacturing/distributing pharmaceutical companies or medical institutions/pharmacies are regulated by the Pharmaceutical Affairs Law of Japan, and this system is important for post-marketing safety features. Although causal relationship between the medicine and the adverse event is not evaluated, and one incidence may be redundantly reported, this information would be useful to roughly grasp the current movements of drug-related serious adverse events, We searched open-source data of the spontaneous reports publicized by Pharmaceutical and Medical Devices Agency for 4 serious adverse events (interstitial lung disease, rhabdomyolysis, anaphylaxis, and Stevens-Johnson syndrome/toxic epidermal necrolysis) from 2004 to 2010 fiscal year (for 2010, from April 1 st to January 31th). Major drug-classes suspected to the adverse events were antineoplastics for interstitial lung disease, hyperlipidemia agents and psychotropics for rhabdomyolysis, antibiotics/chemotherapeutics, antineoplastics and intracorporeal diagnostic agents for anaphylaxis (anaphylactic shock, anaphylactic reactions, anaphylactoid shock and anaphylactoid reactions), and antibiotics/chemotherapeutics, antipyretics and analgesics, anti-inflammatory agents/common cold drugs, and antiepileptics for Stevens-Johnson syndrome/toxic epidermal necrolysis. These results would help understanding of current situations of the 4 drug-related serious adverse events in Japan.
Ventilator-Related Adverse Events: A Taxonomy and Findings From 3 Incident Reporting Systems.

In 2009, researchers from Johns Hopkins University's Armstrong Institute for Patient Safety and Quality; public agencies, including the FDA; and private partners, including the Emergency Care Research Institute and the University HealthSystem Consortium (UHC) Safety Intelligence Patient Safety Organization, sought to form a public-private partnership for the promotion of patient safety (P5S) to advance patient safety through voluntary partnerships. The study objective was to test the concept of the P5S to advance our understanding of safety issues related to ventilator events, to develop a common classification system for categorizing adverse events related to mechanical ventilators, and to perform a comparison of adverse events across different adverse event reporting systems. We performed a cross-sectional analysis of ventilator-related adverse events reported in 2012 from the following incident reporting systems: the Pennsylvania Patient Safety Authority's Patient Safety Reporting System, UHC's Safety Intelligence Patient Safety Organization database, and the FDA's Manufacturer and User Facility Device Experience database. Once each organization had its dataset of ventilator-related adverse events, reviewers read the narrative descriptions of each event and classified it according to the developed common taxonomy. A Pennsylvania Patient Safety Authority, FDA, and UHC search provided 252, 274, and 700 relevant reports, respectively. The 3 event types most commonly reported to the UHC and the Pennsylvania Patient Safety Authority's Patient Safety Reporting System databases were airway/breathing circuit issue, human factor issues, and ventilator malfunction events. The top 3 event types reported to the FDA were ventilator malfunction, power source issue, and alarm failure. Overall, we found that (1) through the development of a common taxonomy, adverse events from 3 reporting systems can be evaluated, (2) the types of events reported in each database were related to the purpose of the database and the source of the reports, resulting in significant differences in reported event categories across the 3 systems, and (3) a public-private collaboration for investigating ventilator-related adverse events under the P5S model is feasible.

Licensed human vaccines can induce various adverse events (AE) in vaccinated patients. Due to the involvement of the whole immune system and complex immunological reactions after vaccination, it is difficult to identify the relations among vaccines, adverse events, and human populations in different age groups. Many known vaccine adverse events (VAEs) have been recorded in the package inserts of US-licensed commercial vaccine products. To better represent and analyze VAEs, we developed the Ontology of Vaccine Adverse Events (OVAE) as an extension of the Ontology of Adverse Events (OAE) and the Vaccine Ontology (VO). Like OAE and VO, OVAE is aligned with the Basic Formal Ontology (BFO). The commercial vaccines and adverse events in OVAE are imported from VO and OAE, respectively. A new population term 'human vaccinee population' is generated and used to define VAE occurrence. An OVAE design pattern is developed to link vaccine, adverse event, vaccinee population, age range, and VAE occurrence. OVAE has been used to represent and classify the adverse events recorded in package insert documents of commercial vaccines licensed by the USA Food and Drug Administration (FDA). OVAE currently includes over 1,300 terms, including 87 distinct types of VAEs associated with 63 human vaccines licensed in the USA. For each vaccine, occurrence rates for every VAE in different age groups have been logically represented in OVAE. SPARQL scripts were developed to query and analyze the OVAE knowledge base data. To demonstrate the usage of OVAE, the top 10 vaccines accompanying with the highest numbers of VAEs and the top 10 VAEs most frequently observed among vaccines were identified and analyzed. Asserted and inferred ontology hierarchies classify VAEs in different levels of AE groups. Different VAE occurrences in different age groups were also analyzed. The ontology-based data representation and integration using the FDA-approved information from the vaccine package insert documents enables the identification of adverse events from vaccination in relation to predefined parts of the population (age groups) and certain groups of vaccines. The resulting ontology-based VAE knowledge base classifies vaccine-specific VAEs and supports better VAE understanding and future rational AE prevention and treatment.

During the period March 1, 1998 to January 14, 2007, approximately 6 million doses of Anthrax vaccine adsorbed (AVA) vaccine were administered. As of January 16, 2007, 4753 reports of adverse events following receipt of AVA vaccination had been submitted to the Vaccine Adverse Event Reporting System (VAERS). Taken together, reports to VAERS did not definitively link any serious unexpected risk to this vaccine, and review of death and serious reports did not show a distinctive pattern indicative of a causal relationship to AVA vaccination. Continued monitoring of VAERS and analysis of potential associations between AVA vaccination and rare, serious events is warranted.
Clinical review: insulin pump-associated adverse events in adults and children.

Insulin pumps are a vital and rapidly developing tool in the treatment of type 1 diabetes mellitus in both adults and children. Many studies have highlighted outcomes and assessed their potential advantages, but much of the data on adverse outcomes are limited and often based on outdated technology. We aimed to review and summarize the available literature on insulin pump-associated adverse events in adults and children. A literature search was undertaken using PubMed, EMBASE, and the Cochrane library. Articles were then screened by title, followed by abstract, and full text as needed. A by-hand search of reference lists in identified papers was also utilised. All searches were limited to English language material, but no time limits were used. Current and past literature regarding insulin pump-associated adverse events is discussed, including potential metabolic and non-metabolic adverse events, in particular: pump malfunction; infusion set/site issues; and cutaneous problems. We show that even with modern technology, adverse events are common, occurring in over 40 % of users per year, with a minority, particularly in children, requiring hospital management. Hyperglycaemia and ketosis are now the most common consequences of adverse events and are usually associated with infusion set failure. This differs from older technology where infected infusion sites predominated. This timely review covers all potential insulin pump-associated adverse events, including their incidence, features, impacts, and contributory factors such as the pump user. The importance of ongoing anticipatory education and support for patients and families using this intensive insulin technology is highlighted, which if done well should improve the overall experience of pump therapy for users, and hopefully reduce the incidence and impact of severe adverse events.

Many centers still admit children for several days to start the ketogenic diet. The exact incidence of adverse effects during the admission and their potential later impact on seizure reduction has not been widely studied. We performed a retrospective study of children with intractable epilepsy electively admitted for ketogenic diet initiation at our institution from 2011 to 2016. Charts were reviewed for adverse effects during the admission period and then examined for seizure reduction and compliance at three months. A rating scale (1 to 4) was created for severity of any adverse events. A total of 158 children were included, with the mean age 4.6 years. Potentially attributable adverse effects occurred in 126 (80%) children, most commonly emesis, food refusal, and hypoglycemia. Seventy-three (46%) children received some form of intervention by the medical team, most commonly the administration of juice (24%). Younger age was correlated with an increased likelihood of moderate to severe adverse effects during admission, often repeated hypoglycemia (3.6 versus 4.9 years, P = 0.04). Fasting was more likely to result in lethargy and a single blood glucose in the 30 to 40 mg/dL range, but it was not correlated with emesis, repeated hypoglycemia, or higher adverse effect scores. There was no statistically significant correlation between the severity of adverse effects and the three-month seizure reduction. Mild easily treated adverse effects occurred in most children admitted for the ketogenic diet. Younger children were at greater risk for significant difficulties and should be monitored closely. Because fasting led to more lethargy and hypoglycemia, it may be prudent to avoid this in younger children. Copyright © 2017 Elsevier Inc. All rights reserved.

Extreme weather and climate-related events occur in a particular place, by definition, infrequently. It is therefore challenging to detect systematic changes in their occurrence given the relative shortness of observational records. However, there is a clear interest from outside the climate science community in the extent to which recent damaging extreme events can be linked to human-induced climate change or natural climate variability. Event attribution studies seek to determine to what extent anthropogenic climate change has altered the probability or magnitude of particular events. They have shown clear evidence for human influence having increased the probability of many extremely warm seasonal temperatures and reduced the probability of extremely cold seasonal temperatures in many parts of the world. The evidence for human influence on the probability of extreme precipitation events, droughts, and storms is more mixed. Although the science of event attribution has developed rapidly in recent years, geographical coverage of events remains patchy and based on the interests and capabilities of individual research groups. The development of operational event attribution would allow a more timely and methodical production of attribution assessments than currently obtained on an ad hoc basis. For event attribution assessments to be most useful, remaining scientific uncertainties need to be robustly assessed and the results clearly communicated. This requires the continuing development of methodologies to assess the reliability of event attribution results and further work to understand the potential utility of event attribution for stakeholder groups and decision makers.

A study in 2011 by (Doody et al. Ir Med J 106(10):300-302, 2013) looked at comparing inpatient adverse events recorded prospectively at the point of care, with adverse events recorded by the national Hospital In-Patient Enquiry (HIPE) System. In the study, a single-centre University Hospital in Ireland treating acute hip fractures in an orthopaedic unit recorded 39 patients over a 2-month (August-September 2011) period, with 55 adverse events recorded prospectively in contrast to the HIPE record of 13 (23.6%) adverse events. With the recent change in the Irish hospital funding model from block grant to an 'activity-based funding' on the basis of case load and case complexity, the hospital financial allocation is dependent on accurate case complexity coding. A retrospective assessment of the financial implications of the two methods of adverse incident recording was carried out. A total of €39,899 in 'missed funding' for 2 months was calculated when the ward-based, prospectively collected data was compared to the national HIPE data. Accurate data collection is paramount in facilitating activity-based funding, to improve patient care and ensure the appropriate allocation of resources.
Adverse life events and health: a population study in Hong Kong.

Although the effects of adverse life events on mental health have been well documented in the literature, there has never been a population based study that investigated systematically the association between history of adverse life events and physical health (objective and subjective) in adults. Cross-sectional, face-to-face household population based survey of adults (18+) in Hong Kong (N=1147). Participants were asked if they had a diagnosis of six health conditions including hypertension, heart disease, arthritis, diabetes, eyesight degeneration, and hearing loss. They were also asked if they had experienced five adverse life events including death of a partner or spouse, abuse, natural disaster, life threatening illness or injury, and family disruption. Interviews also included the Short-Form 12 Health Survey (SFHS-12) and the short version of the Centre for Epidemiologic Studies Depression Scale (CES-D). Overall, results indicate that specific adverse life events may be associated with specific health conditions. However, all tested life events were associated with subjective physical and mental health. Death of partner or parent and life threatening illness or injury were found to have the strongest association with physical health problems. A dose-response relationship between adverse life events and physical health in general was evident but more so for heart disease and eyesight degeneration. Considering the high prevalence of traumatic events and how common the conditions associated with such events are in the general population, screening for adverse life events as part of comprehensive assessment will allow a deeper understanding of patients' needs.

Introduction Migraine headache is a neurological disorder whose attacks are associated with nausea, vomiting, photophobia and phonophobia. Treatments for migraine aim to either prevent attacks before they have started or relieve attacks (abort) after onset of symptoms and range from complementary therapies to pharmacological interventions. A number of treatment-related adverse events such as somnolence, fatigue, and chest discomfort have previously been reported in association with triptans. The comparative tolerability of available agents for the abortive treatment of migraine attacks has not yet been systematically reviewed and quantified. Methods We performed a systematic literature review and Bayesian network meta-analysis for comparative tolerability of treatments for migraine. The literature search targeted all randomized controlled trials evaluating oral abortive treatments for acute migraine over a range of available doses in adults. The primary outcomes of interest were any adverse event, treatment-related adverse events, and serious adverse events. Secondary outcomes were fatigue, dizziness, chest discomfort, somnolence, nausea, and vomiting. Results Our search yielded 141 trials covering 15 distinct treatments. Of the triptans, sumatriptan, eletriptan, rizatriptan, zolmitriptan, and the combination treatment of sumatriptan and naproxen were associated with a statistically significant increase in odds of any adverse event or a treatment-related adverse event occurring compared with placebo. Of the non-triptans, only acetaminophen was associated with a statistically significant increase in odds of an adverse event occurring when compared with placebo. Overall, triptans were not associated with increased odds of serious adverse events occurring and the same was the case for non-triptans. For the secondary outcomes, with the exception of vomiting, all triptans except for almotriptan and frovatriptan were significantly associated with increased risk for all outcomes. Almotriptan was significantly associated with an increased risk of vomiting, whereas all other triptans yielded non-significant lower odds compared with placebo. Generally, the non-triptans were not associated with decreased tolerability for the secondary outcomes. Discussion In summary, triptans were associated with higher odds of any adverse event or a treatment-related adverse event occurring when compared to placebo and non-triptans. Non-significant results for non-triptans indicate that these treatments are comparable with one another and placebo regarding tolerability outcomes.

Concerns with the safety profiles of the newer anticoagulants have been raised because of differences in treatment populations between pre-marketing studies (randomized controlled trials) and clinical practice. Little is known about the potential safety issues and the reporting in spontaneous adverse event databases associated with rivaroxaban. To analyse spontaneous adverse event reports associated with the oral anticoagulant rivaroxaban from Australia, Canada and the USA; and to examine concomitant medicine use that may increase the risk of adverse events. Spontaneous adverse event report databases from Australia, Canada and the USA were examined for all reports of adverse events associated with rivaroxaban and concomitant medicines from 1 August 2005 to 31 March 2013. Disproportionality analysis (the proportional reporting ratio [PRR] and reporting odds ratio [ROR]) was conducted for quantitative detection of signals, using the US database. There were 244 spontaneous adverse event reports associated with rivaroxaban from Australia, 536 from Canada and 1,638 from the USA. Reporting of haemorrhage (any type) was common, ranging from 30.7% for Australia to 37.5% for Canada. Gastrointestinal haemorrhage was the most commonly reported haemorrhage, accounting for 13.9% of Australian, 16.4% of Canadian and 11.1% of US adverse event reports. Positive signals were confirmed in the US data (haemorrhage [any type] PRR 11.93, χ (2) 4,414.78 and ROR 13.41, 95% confidence interval [CI] 12.13-14.81; gastrointestinal haemorrhage PRR 12.52, χ (2) 2,018.48 and ROR 13.15, 95% CI 11.36-15.21). Reporting of concomitant use of medicines with the potential to increase bleeding risk ranged from 63.7% in Australia to 89.2% in Canada. A large proportion of adverse event reports for rivaroxaban were associated with use of concomitant medicines, which may have increased the risk of adverse events-in particular, haemorrhage. Increased awareness of a patient's comorbidity and associated medicine use is needed when rivaroxaban is used in clinical practice.

Serenoa repens (W. Bartram) Small, also known as saw palmetto, is one of the most widely used herbal preparations for the treatment of lower urinary tract symptoms (LUTS) and benign prostatic hyperplasia (BPH). Although a number of randomized controlled trials (RCTs) and systematic reviews of the efficacy of S. repens for the treatment of LUTS and BPH have been published, no systematic review on its drug interactions or adverse events currently exists. This review assesses all available human safety data of S. repens monopreparations. Systematic literature searches were conducted from date of inception to February 2008 in five electronic databases; reference lists and our departmental files were checked for further relevant publications. Information was requested from spontaneous reporting schemes of the WHO and national safety bodies. Twenty-four manufacturers/distributors of S. repens preparations and four herbalist organizations were contacted for additional information. No language restrictions were imposed. Only reports of adverse events in humans from monopreparations of S. repens were included. Data from all articles, regardless of study design, reporting adverse events or interactions were independently extracted by the first author and validated by the second. Forty articles (26 randomized controlled trials, 4 non-randomized controlled trials, 6 uncontrolled trials and 4 case reports/series) were included. They suggest that adverse events associated with the use of S. repens are mild and similar to those with placebo. The most frequently reported adverse events are abdominal pain, diarrhoea, nausea, fatigue, headache, decreased libido and rhinitis. More serious adverse events such as death and cerebral haemorrhage are reported in isolated case reports and data from spontaneous reporting schemes, but causality is questionable. No drug interactions were reported. Currently available data suggest that S. repens is well tolerated by most users and is not associated with serious adverse events. The majority of adverse events are mild, infrequent and reversible, and include abdominal pain, diarrhoea, nausea and fatigue, headache, decreased libido and rhinitis. We found no evidence for drug interactions with S. repens. However, higher quality reporting of adverse events is essential if safety assessments are to be improved in future.

Although research suggests that (a) childhood adversities and more recent stressful life events/conditions are risk factors for panic pathology and that (b) early life stress increases vulnerability to later psychopathology, it remains unclear whether childhood adversities amplify the association between more recent stressful life events/conditions and panic pathology. Data were derived from a general population sample (Study of Health in Pomerania, SHIP). Lifetime panic pathology was assessed with the Munich Composite International Diagnostic Interview (M-CIDI). Childhood adversities (emotional, physical and sexual abuse; emotional and physical neglect) were assessed with the Childhood Trauma Questionnaire (CTQ). More recent separation/loss events and long-lasting stressful conditions were assessed with the Stralsund Life Event List (SEL). Individuals with lifetime panic pathology (fearful spell, panic attack or panic disorder, N = 286) were compared to controls without any psychopathology (N = 286, matched for sex and age). Conditional logistic regressions revealed that childhood adversities as well as more recent separation/loss events and long-lasting stressful conditions were associated with panic pathology (OR 1.1-2.5). Moreover, more recent separation/loss events - but not long-lasting stressful conditions - interacted statistically with each of the examined childhood adversities except for sexual abuse in predicting panic pathology (OR 1.1-1.3). That is, separation/loss events were associated more strongly with panic pathology among individuals with higher childhood adversities. Data were assessed retrospectively and might be subject to recall biases. Findings suggest that early childhood adversities amplify the risk of developing panic pathology after experiencing separation or loss events. Copyright © 2017. Published by Elsevier B.V.

Background While community distribution of topical repellents has been proposed as an additional malaria control intervention, the safety of this intervention at the population level remains poorly evaluated. We describe the safety of mass distribution of the picaridin repellent during a cluster-randomised trial in rural Cambodia in 2012–2013. Methods The repellent was distributed among 57 intervention villages with around 25,000 inhabitants by a team of village distributors. Information on individual adverse events, reported by phone by the village distributors, was obtained through home visits. Information on perceived side effects, reported at the family level, was obtained during two-weekly bottle exchange. Adverse events were classified as adverse reactions (events likely linked to the repellent), cases of repellent abuse and events not related to the repellent use, and classified as per Common Terminology Criteria for Adverse Events. Findings Of the 41 adverse events notified by phone by the village distributors, there were 22 adverse reactions, 11 cases of repellent abuse (6 accidental, 5 suicide attempts) and 8 non-related events. All adverse reactions were mild, occurred in the first few months of use, and mainly manifested as skin conditions. Of the 11 cases of abuse, 2 were moderate and 2 life-threatening. All cases with adverse reactions and repellent abuse recovered completely. 20% of families reported perceived side effects, mainly itching, headache, dizziness and bad smell, but few discontinued repellent use. Conclusions Adverse reactions and abuse during mass use of picaridin were uncommon and generally mild, supporting the safety of the picaridin repellent for malaria control. PMID:28339462

Background Home care (HC) is a critical component of the ongoing restructuring of healthcare in Canada. It impacts three dimensions of healthcare delivery: primary healthcare, chronic disease management, and aging at home strategies. The purpose of our study is to investigate a significant safety dimension of HC, the occurrence of adverse events and their related outcomes. The study reports on the incidence of HC adverse events, the magnitude of the events, the types of events that occur, and the consequences experienced by HC clients in the province of Ontario. Methods A retrospective cohort design was used, utilizing comprehensive secondary databases available for Ontario HC clients from the years 2008 and 2009. The data were derived from the Canadian Home Care Reporting System, the Hospital Discharge Abstract Database, the National Ambulatory Care Reporting System, the Ontario Mental Health Reporting System, and the Continuing Care Reporting System. Descriptive analysis was used to identify the type and frequency of the adverse events recorded and the consequences of the events. Logistic regression analysis was used to examine the association between the events and their consequences. Results The study found that the incident rate for adverse events for the HC clients included in the cohort was 13%. The most frequent adverse events identified in the databases were injurious falls, injuries from other than a fall, and medication-related incidents. With respect to outcomes, we determined that an injurious fall was associated with a significant increase in the odds of a client requiring long-term-care facility admission and of client death. We further determined that three types of events, delirium, sepsis, and medication-related incidents were associated directly with an increase in the odds of client death. Conclusions Our study concludes that 13% of clients in homecare experience an adverse event annually. We also determined that an injurious fall was the most frequent of the adverse events and was associated with increased admission to long-term care or death. We recommend the use of tools that are presently available in Canada, such as the Resident Assessment Instrument and its Clinical Assessment Protocols, for assessing and mitigating the risk of an adverse event occurring.

Background Former studies suggest that prior exposure to adverse experiences such as violence or sexual abuse increases vulnerability to posttraumatic stress reactions in victims of subsequent trauma. However, little is known about how such a history affects responses to terror in the general adolescent population. Objective To explore the role of prior exposure to adverse experiences as risk factors for posttraumatic stress reactions to the Oslo Terror events. Method We used data from 10,220 high school students in a large cross-sectional survey of adolescents in Norway that took place seven months after the Oslo Terror events. Prior exposure assessed was: direct exposure to violence, witnessing of violence, and unwanted sexual acts. We explored how these prior adversities interact with well-established risk factors such as proximity to the events, perceived life threat during the terror events, and gender. Results All types of prior exposure as well as the other risk factors were associated with terror-related posttraumatic stress reactions. The effects of prior adversities were, although small, independent of adolescents’ proximity to the terror events. Among prior adversities, only the effect of direct exposure to violence was moderated by perceived life threat. Exposure to prior adversities increased the risk of posttraumatic stress reactions equally for both genders, but proximity to the terror events and perceived life threat increased the risk more in females. Conclusions Terror events can have a more destabilizing impact on victims of prior adversities, independent of their level of exposure. The findings may be relevant to mental health workers and others providing post-trauma health care. PMID:24872862

The association between measurements of the patient safety culture and the "true" patient safety has been insufficiently documented, and the validity of the tools used for the measurements has been questioned. This study explored associations between the patient safety culture and adverse events, and evaluated the validity of the tools. In 2008/2009, a survey on patient safety culture was performed with Hospital Survey on Patient Safety Culture (HSOPSC) in two medical departments in two geographically separated hospitals of Innlandet Hospital Trust. Later, a retrospective analysis of adverse events during the same period was performed with the Global Trigger Tool (GTT). The safety culture and adverse events were compared between the departments. 185 employees participated in the study, and 272 patient records were analysed. The HSOPSC scores were lower and adverse events less prevalent in department 1 than in department 2. In departments 1 and 2 the mean HSOPSC scores (SD) were at the unit level 3.62 (0.42) and 3.90 (0.37) (p < 0.001), and at the hospital level 3.35 (1.53) and 3.67 (0.53) (ns, p = 0.19) respectively. The proportion of records with adverse events were 10/135 (7%) and 28/137 (20%) (p = 0.003) respectively. There was an inverse association between the patient safety culture and adverse events. Until the criterion validity of the tools for measuring patient safety culture and tracking of adverse events have been further evaluated, measurement of patient safety culture could not be used as a proxy for the "true" safety.

A post hoc pooled analysis was undertaken to evaluate the safety of saxagliptin in patients with type 2 diabetes mellitus, with attention to events of special interest for dipeptidyl peptidase-4 inhibitors. Pooled analyses were performed for 20 randomized controlled studies (N = 9156) of saxagliptin as monotherapy or add-on therapy, and a subset of 11 saxagliptin + metformin studies. Adverse events and events of special interest (gastrointestinal adverse events, infections, hypersensitivity, pancreatitis, skin lesions, lymphopenia, thrombocytopenia, hypoglycaemia, bone fracture, severe cutaneous adverse reactions, opportunistic infection, angioedema, malignancy, worsening renal function, and specific laboratory events) were assessed; incidence rates (events/100 person-years) and incidence rates ratios (saxagliptin/control) were calculated (Mantel-Haenszel method). In both pooled datasets, the incidence rates for deaths, serious adverse events, discontinuations due to adverse events, pancreatitis, malignancy, and most other events of special interest, excepting bone fractures and hypersensitivity, were similar between treatments, with 95% confidence intervals (CIs) for incidence rates ratios including 1. In the 20-study pool, the incidence rates per 100 person-years was higher with saxagliptin versus control for bone fractures [1.1 vs 0.6; incidence rates ratio (95% CI), 1.81 (1.04-3.28)] and hypersensitivity adverse events [1.3 vs 0.8; 1.67 (1.01-2.87)]. Pooled data from 20 studies confirm that saxagliptin has a favourable safety and benefit-risk profile. Copyright © 2013 John Wiley & Sons, Ltd.

Neurological and psychiatric syndromes, collectively referred to as NPSLE, occur frequently in SLE. The frequency of NPSLE varies from 21 to 95%; however, only 13-38% of neuropsychiatric (NP) events could be attributable to SLE in the NPSLE SLICC inception cohort. This variability in the frequency of NPSLE is attributable to the low specificity of the ACR case definitions for SLE-attributed NP syndromes, inclusion of minor NP events in the ACR nomenclature, difficulty in ascertainment of NP events and diverse experience of rheumatologists in the clinical assessment of NP events. Making the correct and early attribution of NP events to SLE is important to institute appropriate immunosuppressive treatment for favourable outcomes. Various attribution models using composite decision rules have been developed and used to ascribe NP events to SLE. This review will focus on the various clinical presentations, diagnostic work-up and attributions of the common NPSLE syndromes, including other NP events not included in the ACR nomenclature but which have come to attention in recent years. © The Author 2016.

Adverse drug events and the Freedom of Information Act: an apple in Eden.
Stang, P E; Fox, J L
1992-02-01
To review some of the abuses and proper uses of the Food and Drug Administration's (FDA's) spontaneous adverse-reaction reporting system, as a way of educating the reader to its strengths and limitations. Published literature and reports based on information obtained from the FDA's database of spontaneous adverse drug-event reports. The Freedom of Information Act has increased public access to the FDA's database of spontaneous adverse drug reaction reports. As these reports are voluntarily received and reported to the FDA, their use for comparisons of drug safety is severely limited. Despite these limitations and the FDA's caveats for use of these data, consumer advocacy groups, researchers, and various pharmaceutical marketing groups have used this source to project the incidence of adverse drug reactions. The FDA's spontaneous adverse-event reporting system is designed to generate signals of unexpected adverse drug events. Use of the data gathered by this system to make drug safety comparisons is beyond their credible scope because many factors influence the reporting of adverse events. Researchers and peer reviewers should place these data in the proper perspective and support sound research into questions of drug safety.

We investigated mental disorders, suicidal ideation, self-perceived need for treatment, and mental health service utilization attributable to exposure to peacekeeping and combat operations among Canadian military personnel. With data from the Canadian Community Health Survey Cycle 1.2 Canadian Forces Supplement, a cross-sectional population-based survey of active Canadian military personnel (N = 8441), we estimated population attributable fractions (PAFs) of adverse mental health outcomes. Exposure to either combat or peacekeeping operations was associated with posttraumatic stress disorder (men: PAF = 46.6%; 95% confidence interval [CI] = 27.3, 62.7; women: PAF = 23.6%; 95% CI = 9.2, 40.1), 1 or more mental disorder assessed in the survey (men: PAF = 9.3%; 95% CI = 0.4, 18.1; women: PAF = 6.1%; 95% CI = 0.0, 13.4), and a perceived need for information (men: PAF = 12.3%; 95% CI = 4.1, 20.6; women: PAF = 7.9%; 95% CI = 1.3, 15.5). A substantial proportion, but not the majority, of mental health-related outcomes were attributable to combat or peacekeeping deployment. Future studies should assess traumatic events and their association with physical injury during deployment, premilitary factors, and postdeployment psychosocial factors that may influence soldiers' mental health.

The adverse events of the dietary supplements should be subject to scrutiny due to their growing clinical application and consumption among U.S. adults. An effective method for mining and grouping the adverse events of the dietary supplements is to evaluate product labeling for the rapidly increasing number of new products available in the market. In this study, the adverse events information was extracted from the product labels stored in the Dietary Supplement Label Data-base (DSLD) and analyzed by topic modeling techniques, specifically Latent Dirichlet Allocation (LDA). Among the 50 topics generated by LDA, eight topics were manually evaluated, with topic relatedness ranging from 58.8% to 100% on the product level, and 57.1% to 100% on the ingredient level. Five out of these eight topics were coherent groupings of the dietary supplements based on their adverse events. The results demonstrated that LDA is able to group supplements with similar adverse events based on the dietary supplement labels. Such information can be potentially used by consumers to more safely use dietary supplements.

It has been published that hospital adverse events are an important source of morbidity and mortality in different countries and settings. The aim of this study was to evaluate the frequency, magnitude, distribution and degree of preventability of adverse events in the Autonomous Community of Catalonia (Spain). We conducted a retrospective cohort study of 4,790 hospital discharges that were selected by simple random sampling after stratified multistage sampling in 15 hospitals in Catalonia. 38.25% of patients had positive risk criteria (screening phase). We identified 356 cases of adverse events, which represent a 7.4% (95%CI: 6.7% to 8.1%). Of these, 43.5% (155 cases) were considered preventable. This study confirms that adverse events in hospitals in Catalonia are frequent, and generate a significant impact on morbidity and mortality. As in other studies, corroborated that a high proportion of these adverse events are considered preventable. It was possible to identify priority areas to focus improvement efforts. Copyright © 2014.

Among the 50 topics generated by LDA, eight topics were manually evaluated, with topic relatedness ranging from 58.8% to 100% on the product level, and 57.1% to 100% on the ingredient level. Five out of these eight topics were coherent groupings of the dietary supplements based on their adverse events. The results demonstrated that LDA is able to group supplements with similar adverse events based on the dietary supplement labels. Such information can be potentially used by consumers to more safely use dietary supplements. PMID:29295169
Exploration of a Preflight Acuity Scale for Fixed Wing Air Ambulance Transport.
Phipps, Marcy; Conley, Virginia; Constantine, William H
Despite the prevalence of fixed wing medical flights for specialized care and repatriation, few acuity rating scales exist aimed at the prediction of adverse in-flight medical events. An acuity scoring system can provide information to flight crews, allowing for staffing enhancements, protocol modifications, and flight planning, with the aim of improving patient care, outcomes, and preventing losses to providers because of costly diversions. Our medical crew developed an acuity scale, which was applied retrospectively to 296 patients transported between January 2016 and March 2017. Patients received scores based on conditions identified during the preflight medical report, the initial patient assessment, demographics, and flight factors. Five patients were identified as high-risk transports based on our scale. Three patients suffered adverse events according to our defined criteria, 2 of which occurred before transport and 1 during transport. The 3 patients suffering adverse events did not receive a score that indicated adverse events in flight. Our scale was not predictive of adverse events in flight. However, it did illuminate factors worthy of consideration. Consideration of these factors may have prevented adverse events. Published by Elsevier Inc.

Drug-related adverse events pose substantial risks to patients who consume post-market or Drug-related adverse events pose substantial risks to patients who consume post-market or investigational drugs. Early detection of adverse events benefits not only the drug regulators, but also the manufacturers for pharmacovigilance. Existing methods rely on patients' "spontaneous" self-reports that attest problems. The increasing popularity of social media platforms like the Twitter presents us a new information source for finding potential adverse events. Given the high frequency of user updates, mining Twitter messages can lead us to real-time pharmacovigilance. In this paper, we describe an approach to find drug users and potential adverse events by analyzing the content of twitter messages utilizing Natural Language Processing (NLP) and to build Support Vector Machine (SVM) classifiers. Due to the size nature of the dataset (i.e., 2 billion Tweets), the experiments were conducted on a High Performance Computing (HPC) platform using MapReduce, which exhibits the trend of big data analytics. The results suggest that daily-life social networking data could help early detection of important patient safety issues.

Secondary analysis of prospectively collected observational data assessing the safety of an autonomic dysreflexia (AD) management protocol. To estimate the time to onset of action, time to full clinical effect (sustained systolic blood pressure (SBP) <160 mm Hg) and effectiveness of nitroglycerin ointment at lowering blood pressure for patients with spinal cord injuries experiencing AD. US Veterans Affairs inpatient spinal cord injury (SCI) unit. Episodes of AD recalcitrant to nonpharmacologic interventions that were given one to two inches of 2% topical nitroglycerin ointment were recorded. Pharmacodynamics as above and predictive characteristics (through a mixed multivariate logistic regression model) were calculated. A total of 260 episodes of pharmacologically managed AD were recorded in 56 individuals. Time to onset of action for nitroglycerin ointment was 9-11 min. Time to full clinical effect was 14-20 min. Topical nitroglycerin controlled SBP <160 mm Hg in 77.3% of pharmacologically treated AD episodes with the remainder requiring additional antihypertensive medications. A multivariate logistic regression model was unable to identify statistically significant factors to predict which patients would respond to nitroglycerin ointment (odds ratios 95% confidence intervals 0.29-4.93). The adverse event rate, entirely attributed to hypotension, was 3.6% with seven of the eight events resolving with close observation alone and one episode requiring normal saline. Nitroglycerin ointment has a rapid onset of action and time to full clinical effect with high efficacy and relatively low adverse event rate for patients with SCI experiencing AD.

To retrospectively assess serious systemic adverse effects of standardized dust-mite vaccine in children with asthma. Medical records of 704 children (5-17 years in age) with asthma between January, 2005 and December, 2011 were reviewed. Serious systemic adverse events following treatment with a standardized dust-mite vaccine in these children were analyzed. A total of 336 systemic adverse reactions were observed in 17.0% (120/704) of the patients analyzed of these adverse reactions, 18 (5.4%) were serious (level 3), 318 (94.6%) were not serious (below level 3), and no single case of anaphylactic shock (level 4) was recorded. Systemic adverse events occurred most frequently in the 5 to 11-year age group and in the summer season (from June to August). In the 18 severe cases, the peak expiratory flow (PEF) dropped by 20% immediately after the vaccine injection, and other major clinical symptoms included cough, wheezing and urticaria. All children with serious systemic adverse effects were given inhaled hormone and atomized short-acting beta agonists, oral antihistamines, intravenous dexamethasone and/or intramuscular adrenaline. After these treatments, the clinical symptoms were significantly relieved. The rate of serious systemic adverse events following allergen-specific immunotherapy is relatively low in children with allergic asthma. Conventional medications are effective in managing these immunotherapy-associated adverse events.

Delayed vasospasm (VSP) following aneurysmal subarachnoid hemorrhage (aSAH) remains a major source of morbidity. Milrinone was recently suggested as an invasive VSP treatment option. It is a phosphodiesterase III inhibitor with vasodilating and additional positive inotrope and anti-inflammatory effects. In this preliminary series, we included patients with severe VSP and unsuccessful maximum conservative therapy. Inclusion criteria were (1) transcranial Doppler (TCD) mean >180 cm/s; (2) increase of >50 % of TCD mean values within 6 h to values >150 cm/s; and/or (3) neurological deterioration (after exclusion of hemorrhage, hydrocephalus, and other systemic reasons). Patients received endovascular therapy with nimodipine 2 mg followed by milrinone 4-8 mg. Reinterventions were indicated aggressively in cases of persistent neurological deficits or persistent high mean TCD >180 cm/s. Of 121 consecutive aSAH patients, 16 (13.2 %) received endovascular VSP therapy. Of these, 11 patients (68.5 %) received ≥ 3 interventions (median 4; maximum 9); 14 (87.5 %) showed postinterventional angiographic improvement of vessel diameters; and 11 (68.5 %) showed improvement of their neurological deficits after a mean follow-up time of 4.5 months. No cardiovascular adverse events attributed to milrinone were observed. Milrinone may be a useful supplementary substance for endovascular VSP therapy. Aggressive reintervention indications did not cause additional adverse events.
Indoor tanning injuries: an evaluation of FDA adverse event reporting data.
Dowdy, John C; Sayre, Robert M; Shepherd, James G
2009-08-01
In 1979 the Food and Drug Administration (FDA) designated indoor tanning units would be regulated medical devices and that each must have an exposure timer. In 1985 FDA added a scheduled series of doses designed to allow tanning with little risk of concomitant sunburn. Subsequently FDA/CDRH maintained databases in which medical device associated injuries were reported. The databases, MAUDE and its predecessor MDR, are available online. While these records, in part, are not intended for evaluation of adverse event rates, analysis provides insight into the etiology of UV-related tanning injuries. We compiled 142 records reported for 1985-2006 including 22% noninjury malfunctions. Of the reported injuries approximately 50% resulted from UV exposure, an average of <1/year resulted in hospitalization. At least 36% of the UV-related injuries were attributable to various (user/operator) noncompliance with FDA sunlamp guidance policies. During 1985-1995 there were six times more UV injuries than 1996-2006, presumably reflecting cessation of much mandatory reporting in 1996. Injury reports declined steady from 1997 to 2006. FDA guidance appears most efficacious in injury prevention and we encourage its incorporation into the enforceable performance standard. We also advise that tanning industry professional training programs seek standardization/accreditation of their personnel certifications through recognized accreditation bodies such as ANSI or ISO/IEC.

The use of herbal products continues to expand rapidly across the world and concerns regarding the safety of these products have been raised. In Thailand, Thai Vigibase, developed by the Health Product Vigilance Center (HPVC) under the Thai Food and Drug Administration, is the national database that collates reports from health product surveillance systems and programmes. Thai Vigibase can be used to identify signals of adverse events in patients receiving herbal products. The purpose of the study was to describe the characteristics of reported adverse events in patients receiving herbal products in Thailand. Thai Vigibase data from February 2000 to December 2008 involving adverse events reported in association with herbal products were used. This database includes case reports submitted through the spontaneous reporting system and intensive monitoring programmes. Under the spontaneous reporting system, adverse event reports are collected nationwide via a national network of 22 regional centres covering more than 800 public and private hospitals, and health service centres. An intensive monitoring programme was also conducted to monitor the five single herbal products listed in the Thai National List of Essential Medicines (NLEM), while another intensive monitoring programme was developed to monitor the four single herbal products that were under consideration for inclusion in the NLEM. The database contained patient demographics, adverse events associated with herbal products, and details on seriousness, causality and quality of reports. Descriptive statistics were used for data analyses. A total of 593 reports with 1868 adverse events involving 24 different products were made during the study period. The age range of individuals was 1-86 years (mean 47 years). Most case reports were obtained from the intensive monitoring programme. Of the reports, 72% involved females. The herbal products for which adverse events were frequently reported were products containing turmeric (44%), followed by andrographis (10%), veld grape (10%), pennywort (7%), plai (6%), jewel vine (6%), bitter melon (5%) and snake plant (5%). Gastrointestinal problems were the most common adverse effect reported. Serious adverse events included Stevens-Johnson syndrome, anaphylactic shock and exfoliative dermatitis. Adverse event reports on herbals products were diverse, with most of them being reported through intensive monitoring programmes. Thai Vigibase is a potentially effective data source for signal detection of adverse events associated with herbal products.

To study the type and frequency of adverse events associated with anti-tumor necrosis factor (TNF) therapy and evaluate for any serologic and genetic associations. This study was a retrospective review of patients attending the inflammatory bowel disease (IBD) centers at Cedars-Sinai IBD Center from 2005-2016. Adverse events were identified via chart review. IBD serologies were measured by ELISA. DNA samples were genotyped at Cedars-Sinai using Illumina Infinium Immunochipv1 array per manufacturer's protocol. SNPs underwent methodological review and were evaluated using several SNP statistic parameters to ensure optimal allele-calling. Standard and rigorous QC criteria were applied to the genetic data, which was generated using immunochip. Genetic association was assessed by logistic regression after correcting for population structure. Altogether we identified 1258 IBD subjects exposed to anti-TNF agents in whom Immunochip data were available. 269/1258 patients (21%) were found to have adverse events to an anti-TNF-α agent that required the therapy to be discontinued. 25% of women compared to 17% of men experienced an adverse event. All adverse events resolved after discontinuing the anti-TNF agent. In total: n = 66 (5%) infusion reactions; n = 49 (4%) allergic/serum sickness reactions; n = 19 (1.5%) lupus-like reactions, n = 52 (4%) rash, n = 18 (1.4%) infections. In Crohn's disease, IgA ASCA ( P = 0.04) and IgG-ASCA ( P = 0.02) levels were also lower in patients with any adverse events, and anti-I2 level in ulcerative colitis was significantly associated with infusion reactions ( P = 0.008). The logistic regression/human annotation and network analyses performed on the Immunochip data implicated the following five signaling pathways: JAK-STAT (Janus Kinase-signal transducer and activator of transcription), measles, IBD, cytokine-cytokine receptor interaction, and toxoplasmosis for any adverse event. Our study shows 1 in 5 IBD patients experience an adverse event to anti-TNF therapy with novel serologic, genetic , and pathways associations.

To describe adverse events occurring after mass vaccination with conjugate and nonconjugate vaccines and to assess the incidence of serious adverse effects. A mass immunisation campaign against meningococcal C disease was conducted in two French administrative areas, Landes and Pyrénées atlantiques, for 2 months (from October to December 2002). Adverse events were reported by families and physicians by means of a specific reporting form returned to the pharmacovigilance centre 15 days after vaccination. The target population was 260,630 individuals aged between 2 months and 24 years. About 179,000 children and young adults were vaccinated. A total of 92,711 report forms were received by the pharmacovigilance centre, and 12,695 subjects presented at least one adverse event. The most frequently involved systems/disorders were application site disorders (48.4%), whole-body general disorders (21.8%), central and peripheral nervous system disorders (14.6%), and gastrointestinal system disorders (4.7%). Most of these adverse events were transient and not serious. There were 13 serious adverse events: one each of syncope, fever, headache with fever, neuralgia, serum sickness, arthritis, purpura, facial paralysis, multiple sclerosis, lipoma, and meningism, and two cases of bronchospasm. No significant difference was found in rates of adverse event reports between both vaccines. The estimated incidence of serious adverse effect reports was 7 per 100,000. This campaign was the second immunisation campaign undertaken in France involving both physicians and families as reporters. Although unlabeled adverse effects were identified during this campaign, they were mostly nonserious and have been known to occur with other vaccines.

The prediction of anomalies or adverse events is a challenging task, and there are a variety of methods which can be used to address the problem. In this paper, we introduce a generic framework developed in MATLAB (sup registered mark) called ACCEPT (Adverse Condition and Critical Event Prediction Toolbox). ACCEPT is an architectural framework designed to compare and contrast the performance of a variety of machine learning and early warning algorithms, and tests the capability of these algorithms to robustly predict the onset of adverse events in any time-series data generating systems or processes.
Patterns in spontaneous adverse event reporting among branded and generic antiepileptic drugs.
Bohn, J; Kortepeter, C; Muñoz, M; Simms, K; Montenegro, S; Dal Pan, G
2015-05-01
Spontaneous adverse event reports constitute an important source of information on previously unknown adverse reactions to marketed medicines. However, the dynamics of such reporting following generic introduction are poorly understood. Using adverse event reports on five antiepileptic drugs from the US Food and Drug Administration's Adverse Event Reporting System, we describe temporal trends in adverse event reporting before and after generic introduction, and survey the quality of product-identifying information contained therein. The majority of reports were sent by innovator drug manufacturers while few were sent by generic manufacturers, even when generics accounted for >90% of dispensed prescriptions. We manually reviewed narratives from 2,500 reports and found that the suspect product type (brand or generic) could not be determined in 84% of reports, while generic products (16%) were identified more often than brand-name products (<1%). These results suggest that pharmacovigilance stakeholders should act to promote more detailed reporting practices. © 2015 American Society for Clinical Pharmacology and Therapeutics.

Childhood adverse events are risk factors for later bipolar disorder. We quantified the risks for a later diagnosis of bipolar disorder after exposure to adverse life events in children with and without parental psychopathology. This register-based population cohort study included all persons born in Denmark from 1980 to 1998 (980 554 persons). Adversities before age 15 years were: familial disruption; parental somatic illness; any parental psychopathology; parental labour market exclusion; parental imprisonment; placement in out-of-home care; and parental natural and unnatural death. We calculated risk estimates of each of these eight life events as single exposure and risk estimates for exposure to multiple life events. Main outcome variable was a diagnosis of bipolar disorder after the age of 15 years, analysed with Cox proportional hazard regression. Single exposure to most of the investigated adversities were associated with increased risk for bipolar disorder, exceptions were parental somatic illness and parental natural death. By far the strongest risk factor for bipolar disorder in our study was any mental disorder in the parent (hazard ratio 3.53; 95% confidence interval 2.73-4.53) and the additional effects of life events on bipolar risk were limited. An effect of early adverse life events on bipolar risk later in life was mainly observed in children without parental psychopathology. Our findings do not exclude early-life events as possible risk factors, but challenge the concept of adversities as important independent determinants of bipolar disorder in genetically vulnerable individuals.

Cinnamon, from the genus Cinnamomum and Lauraceae family, has been used as a popular spice for thousands of years around the world. Many studies have shown therapeutic effects of cinnamon including its antimicrobial, antiviral, antifungal, antioxidant, antitumor, antihypertensive, antilipemic, antidiabetic, gastroprotective, and immunomodulatory effects. Due to popular use of cinnamon and several human reports on adverse events associated with short or long term use of cinnamon, we aimed to systematically review its human reports of adverse event. Databases including Medline, Scopus, Science Direct, Embase, PubMed Central and Google scholar were searched using the key words "cinnamon" or "cinnamomum" for clinical trials, case reports and case series. Also spontaneous reports about adverse effects of cinnamon were collected from five national and international spontaneous reporting schemes. Thirty eight clinical trials were found, five of them reported adverse events. Twenty case reports and seven case series, as well as, spontaneous reports including 160 adverse events were also included. The most frequent adverse events were gastrointestinal disorders and allergic reactions which were self-limiting in the majority of cases. The available data suggests that despite the safety of cinnamon use as a spice and/or flavoring agent, its use may be associated with significant adverse effects in medicinal uses with larger doses or longer duration of use and should be clinically monitored.

To describe the approach to the communication and blame of an adverse by nursing students. A descriptive study on disclosure and apologies for adverse events by nursing students in the academic years 2011-12 and 2012-13. The study included group discussion and drafting a written communication to the injured patient about adverse events during hospitalization. An ad hoc checklist was used and an analysis was performed on items related to the disclosure and apologies issues. A total of 126 nursing students were involved, and they created 21 written The facts about adverse events were reported in 81% of written communications, and 47.1% chose an abbreviated disclosure of the facts with no detailed explanation of adverse events. The facts were accurately reproduced in only 9.5% of written communications to the patients. One third (33.3%) apologized for the mistakes, and 47.6% required that the communication was signed by the Management. All (100%) of the nursing students chose not to report the health professionals who had participated during the events. There is a fear to acknowledge errors within health centers. It is recommended that tools are developed for these future nursing professionals to make an open and honest disclosure of adverse events, as well as the apologies for them.

Science on the role of anthropogenic influence on extreme weather events, such as heatwaves or droughts, has evolved rapidly in the past years. The approach of "event attribution" compares the occurrence-probability of an event in the present, factual climate with its probability in a hypothetical, counterfactual climate without human-induced climate change. Several methods can be used for event attribution, based on climate model simulations and observations, and usually researchers only assess a subset of methods and data sources. Here, we explore the role of methodological choices for the attribution of the 2015 meteorological summer drought in Europe. We present contradicting conclusions on the relevance of human influence as a function of the chosen data source and event attribution methodology. Assessments using the maximum number of models and counterfactual climates with pre-industrial greenhouse gas concentrations point to an enhanced drought risk in Europe. However, other evaluations show contradictory evidence. These results highlight the need for a multi-model and multi-method framework in event attribution research, especially for events with a low signal-to-noise ratio and high model dependency such as regional droughts.
Extreme Weather Events and Climate Change Attribution

Thomas, Katherine
A report from the National Academies of Sciences, Engineering, and Medicine concludes it is now possible to estimate the influence of climate change on some types of extreme events. The science of extreme event attribution has advanced rapidly in recent years, giving new insight to the ways that human-caused climate change can influence the magnitude or frequency of some extreme weather events. This report examines the current state of science of extreme weather attribution, and identifies ways to move the science forward to improve attribution capabilities. Confidence is strongest in attributing types of extreme events that are influenced by climatemore » change through a well-understood physical mechanism, such as, the more frequent heat waves that are closely connected to human-caused global temperature increases, the report finds. Confidence is lower for other types of events, such as hurricanes, whose relationship to climate change is more complex and less understood at present. For any extreme event, the results of attribution studies hinge on how questions about the event's causes are posed, and on the data, modeling approaches, and statistical tools chosen for the analysis.« less

Attributions, attempts to link an event with its causes, enable people to understand and react to their surroundings. Because attributions are directly related to understanding events, and because this understanding influences how individuals then deal with events, attributions play a vital role in the coping process.

Ertapenem-associated neurotoxicity in the Spinal Cord Injury (SCI) population: a case series.
Patel, Ursula C; Fowler, Mallory A
2017-09-06
Context Ertapenem, a broad spectrum carbapenem antibiotic, is used often in Spinal Cord Injury (SCI) patients due to increased risk factors for multi-drug resistant (MDR) infections in this population. Neurotoxicity, specifically seizures, due to ertapenem is a known adverse effect and has been described previously. Other manifestations such as delirium and visual hallucinations have rarely been reported, and no literature, to the best of our knowledge, specifically describes these effects solely in the SCI population. Findings Four cases of mental status changes and hallucinations in SCI patients attributed to ertapenem therapy are described. Onset of symptoms began between one and six days following initiation of ertapenem and resolved between two to 42 days following discontinuation. Based on the Naranjo probability scale, a probable relationship exists between the adverse events and ertapenem for three out of the four cases. Possible overestimation of renal function and hypoalbuminemia may be contributing factors to the noted adverse reactions. Conclusion/Clinical Relevance The cases described highlight the importance of recognizing ertapenem-associated hallucinations in SCI patients. The population is particularly vulnerable due to risk factors for MDR infections necessitating ertapenem use, possible overestimation of renal function, and a high prevalence of hypoalbuminemia.

Objective To review all admissions (age > 13) to three surgical patient care centers at a single academic medical center between January 1, 1995, and December 6, 1999, for significant surgical adverse events. Summary Background Data Little data exist on the interrelationships between surgical adverse events, risk management, malpractice claims, and resulting indemnity payments to plaintiffs. The authors hypothesized that examination of this process would identify performance improvement opportunities overlooked by standard medical peer review; the risk of litigation would be constant across the three homogeneous patient care centers; and the risk management process would exceed the performance improvement process. Methods Data collected included patient demographics (age, gender, and employment status), hospital financials (hospital charges, costs, and financial class), and outcome. Outcome categories were medical (disability: <1 month, 1–6 months, permanent/death), legal (no legal action, settlement, summary judgment), financial (indemnity payments, legal fees, write-offs), and cause and effect analysis. Cause and effect analysis attempts to identify system failures contributing to adverse outcomes. This was determined by two independent analysts using the 17 Harvard criteria and subdividing these into subsystem causative factors. Results The study group consisted of 130 patients with surgical adverse events resulting in total liabilities of $8.2 million. The incidence of adverse events per 1,000 admissions across the three patient care centers was similar, but indemnity payments per 1,000 admissions varied (cardiothoracic = $30, women’s health = $90, trauma = $520). Patient demographics were not predictive of high-risk subgroups for adverse events or litigation. In terms of medical outcome, 51 patients had permanent disability or death, accounting for 98% of the indemnity payments. In terms of legal outcome, 103 patients received no indemnity payments, 15 patients received indemnity payments, four suits remain open, and in eight cases charges were written off ($0.121 million). To date, no cases have been adjudicated in court. Cause and effect analysis identified 390 system failures contributing to the adverse events (mean 3.0 failures per adverse event); there were 4.7 failures per adverse event in the 15 indemnity cases. Five categories of causes accounted for 75% of the failures (patient management, n = 104; communication, n = 89; administration, n = 33; documentation, n = 32; behavior, n = 23). The current medical review process would have identified 104 of 390 systems failures (37%). Conclusions This study demonstrates no rational link between the tort system and the reduction of adverse events. Sixty-three percent of contributing causes to adverse events were undetected by current medical review processes. Adverse events occur at the interface between different systems or disciplines and result from multiple failures. Indemnity costs per hospital day vary dramatically by patient care center (range $3.60–97.60 a day). The regionalization of healthcare is in jeopardy from the burden of high indemnity payments.

Vaccine adverse events (VAEs) are adverse bodily changes occurring after vaccination. Understanding the adverse event (AE) profiles is a crucial step to identify serious AEs. Two different types of seasonal influenza vaccines have been used on the market: trivalent (killed) inactivated influenza vaccine (TIV) and trivalent live attenuated influenza vaccine (LAIV). Different adverse event profiles induced by these two groups of seasonal influenza vaccines were studied based on the data drawn from the CDC Vaccine Adverse Event Report System (VAERS). Extracted from VAERS were 37,621 AE reports for four TIVs (Afluria, Fluarix, Fluvirin, and Fluzone) and 3,707 AE reports for the only LAIV (FluMist). The AE report data were analyzed by a novel combinatorial, ontology-based detection of AE method (CODAE). CODAE detects AEs using Proportional Reporting Ratio (PRR), Chi-square significance test, and base level filtration, and groups identified AEs by ontology-based hierarchical classification. In total, 48 TIV-enriched and 68 LAIV-enriched AEs were identified (PRR>2, Chi-square score >4, and the number of cases >0.2% of total reports). These AE terms were classified using the Ontology of Adverse Events (OAE), MedDRA, and SNOMED-CT. The OAE method provided better classification results than the two other methods. Thirteen out of 48 TIV-enriched AEs were related to neurological and muscular processing such as paralysis, movement disorders, and muscular weakness. In contrast, 15 out of 68 LAIV-enriched AEs were associated with inflammatory response and respiratory system disorders. There were evidences of two severe adverse events (Guillain-Barre Syndrome and paralysis) present in TIV. Although these severe adverse events were at low incidence rate, they were found to be more significantly enriched in TIV-vaccinated patients than LAIV-vaccinated patients. Therefore, our novel combinatorial bioinformatics analysis discovered that LAIV had lower chance of inducing these two severe adverse events than TIV. In addition, our meta-analysis found that all previously reported positive correlation between GBS and influenza vaccine immunization were based on trivalent influenza vaccines instead of monovalent influenza vaccines.

Background . Fear of adverse events and occurrence of side effects are commonly cited by families and physicians as obstructive to appropriate use of pain medication in children. We examined evidence comparing the safety profiles of three groups of oral medications, acetaminophen, nonsteroidal anti-inflammatory drugs, and opioids, to manage acute nonsurgical pain in children (<18 years) treated in ambulatory settings. Methods . A comprehensive search was performed to July 2015, including review of national data registries. Two reviewers screened articles for inclusion, assessed methodological quality, and extracted data. Risks (incidence rates) were pooled using a random effects model. Results . Forty-four studies were included; 23 reported on adverse events. Based on limited current evidence, acetaminophen, ibuprofen, and opioids have similar nausea and vomiting profiles. Opioids have the greatest risk of central nervous system adverse events. Dual therapy with a nonopioid/opioid combination resulted in a lower risk of adverse events than opioids alone. Conclusions . Ibuprofen and acetaminophen have similar reported adverse effects and notably less adverse events than opioids. Dual therapy with a nonopioid/opioid combination confers a protective effect for adverse events over opioids alone. This research highlights challenges in assessing medication safety, including lack of more detailed information in registry data, and inconsistent reporting in trials.

Although the safety profile of tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccines in adolescents and adults has been documented, few data have reported about their adverse events in children. Healthy 6- to 7-year-old children who were immunized with Tdap vaccine were evaluated for adverse events on Days 1, 2, 4, and 7 postimmunization. Information of sex, body mass index (BMI), and previous diphtheria-pertussis-tetanus (DPT) immunization history was obtained and evaluated for the association with the adverse events. A total of 243 6- to 7-year-old children were immunized with Tdap. Among the 243 children immunized, remarkable adverse events included redness more than or equal to 10 mm in 47 (19%) children, induration more than or equal to 10 mm in 57 (23%), tenderness in 130 (53%), and fever in 12 (5%). Redness and induration resolved in 7 days and fever resolved on Day 4. The adverse events were not associated with gender, BMI above the mean value, or the type of fourth DPT immunization. Adverse events after Tdap vaccination were mild and dissolved within 7 days in 6- to 7-year-old children. Copyright © 2011. Published by Elsevier B.V.

This retrospective analysis assessed the capability of active and passive safety surveillance systems to track product-specific safety events in the USA for branded and generic enoxaparin, a complex injectable subject to immune-related and other adverse events (AEs). Analysis of heparin-induced thrombocytopenia (HIT) incidence was performed on benefit claims for commercial and Medicare supplemental-insured individuals newly treated with enoxaparin under pharmacy benefit (1 January 2009 - 30 June 2012). Additionally, spontaneous reports from the FDA AE Reporting System were reviewed to identify incidence and attribution of enoxaparin-related reports to specific manufacturers. Specific, dispensed products were identifiable from National Drug Codes only in pharmacy-benefit databases, permitting sensitive comparison of HIT incidence in nearly a third of patients treated with brand or generic enoxaparin. After originator medicine's loss of exclusivity, only 5% of spontaneous reports were processed by generic manufacturers; reports attributable to specific generics were approximately ninefold lower than expected based on market share. Claims data were useful for active surveillance of enoxaparin generics dispensed under pharmacy benefits but not for products administered under medical benefits. These findings suggest that the current spontaneous reporting system will not distinguish product-specific safety signals for products distributed by multiple manufacturers, including biosimilars.

Safety signal detection in spontaneous reporting system databases and electronic healthcare records is key to detection of previously unknown adverse events following immunization. Various statistical methods for signal detection in these different datasources have been developed, however none are geared to the pediatric population and none specifically to vaccines. A reference set comprising pediatric vaccine-adverse event pairs is required for reliable performance testing of statistical methods within and across data sources. The study was conducted within the context of the Global Research in Paediatrics (GRiP) project, as part of the seventh framework programme (FP7) of the European Commission. Criteria for the selection of vaccines considered in the reference set were routine and global use in the pediatric population. Adverse events were primarily selected based on importance. Outcome based systematic literature searches were performed for all identified vaccine-adverse event pairs and complemented by expert committee reports, evidence based decision support systems (e.g. Micromedex), and summaries of product characteristics. Classification into positive (PC) and negative control (NC) pairs was performed by two independent reviewers according to a pre-defined algorithm and discussed for consensus in case of disagreement. We selected 13 vaccines and 14 adverse events to be included in the reference set. From a total of 182 vaccine-adverse event pairs, we classified 18 as PC, 113 as NC and 51 as unclassifiable. Most classifications (91) were based on literature review, 45 were based on expert committee reports, and for 46 vaccine-adverse event pairs, an underlying pathomechanism was not plausible classifying the association as NC. A reference set of vaccine-adverse event pairs was developed. We propose its use for comparing signal detection methods and systems in the pediatric population. Published by Elsevier Ltd.

To systematically assess the prevalence of yoga-associated injuries and other adverse events in epidemiological studies. Systematic review of observational studies. Medline/PubMed, Scopus, the Cochrane Library, and IndMed were searched through October 2016 for epidemiological studies assessing the prevalence of adverse events of yoga practice or comparing the risk of any adverse events between yoga practitioners and non-yoga practitioners. Nine observational studies with a total 9129 yoga practitioners and 9903 non-yoga practitioners were included. Incidence proportion of adverse events during a yoga class was 22.7% (95% confidence interval [CI]=21.1%-24.3%); 12-months prevalence was 4.6% (95%CI=3.8%-5.4%), and lifetime prevalence ranged from 21.3% (95%CI=19.7%-22.9%) to 61.8% (95%CI=52.8%-70.8%) of yoga practitioners. Serious adverse events occurred in 1.9% (95%CI=1.4%-2.4%). The most common adverse events related to the musculoskeletal system; the most common injuries were sprains and strains. Compared to non-yoga practitioners, yoga practitioners had a comparable risk of falls (odds ratio [OR]=0.90; 95%CI=0.76-1.08), and falls-related injuries (OR=1.04; 95%CI=0.83-1.29), and higher risk of meniscus injuries (OR=1.72; 95%CI=1.23-2.41). A considerable proportion of yoga practitioners experienced injuries or other adverse events; however most were mild and transient and risks were comparable to those of non-yoga practitioners. There is no need to discourage yoga practice for healthy people. People with serious acute or chronic illnesses should seek medical advice before practicing yoga.

To describe how in-depth analysis of adverse events can reveal underlying causes. Triggers for adverse events were developed using the hospital's computerised medical record (naloxone for opiate-related oversedation and administration of a glucose bolus while on insulin for insulin-related hypoglycaemia). Triggers were identified daily. Based on information from the medical record and interviews, a subject expert determined if an adverse drug event had occurred and then conducted a real-time analysis to identify event characteristics. Expert groups, consisting of frontline staff and specialist physicians, examined event characteristics and determined the apparent cause. 30 insulin-related hypoglycaemia events and 34 opiate-related oversedation events were identified by the triggers over 16 and 21 months, respectively. In the opinion of the experts, patients receiving continuous-infusion insulin and those receiving dextrose only via parenteral nutrition were at increased risk for insulin-related hypoglycaemia. Lack of standardisation in insulin-dosing decisions and variation regarding when and how much to adjust insulin doses in response to changing glucose levels were identified as common causes of the adverse events. Opiate-related oversedation events often occurred within 48 h of surgery. Variation in pain management in the operating room and post-anaesthesia care unit was identified by the experts as potential causes. Variations in practice, multiple services writing orders, multidrug regimens and variations in interpretation of patient assessments were also noted as potential contributing causes. Identification of adverse drug events through an automated trigger system, supplemented by in-depth analysis, can help identify targets for intervention and improvement.

Zoster vaccine is recommended to reduce the incidence of herpes zoster and its complication of postherpetic neuralgia in older adults. However, there have been reports of autoimmune side effects post vaccination. We therefore aim to investigate the possible relationship of severe autoimmune adverse events (arthritis, vasculitis, systemic lupus erythematosus, thrombocytopenia, alopecia, Guillain-Barre syndrome, optic neuritis and multiple sclerosis) post zoster vaccination with a matched case-control study of reported events in the Vaccine Adverse Event Reporting System (VAERS). Our study showed no significantly increased risks of severe autoimmune adverse events, except arthritis and alopecia, after vaccination. Compared to the unexposed, patients with zoster vaccination had 2.2 and 2.7 times the odds of developing arthritis and alopecia, respectively (P<0.001 and P=0.015, respectively). However, almost none of these events was life threatening. Zoster vaccine is, therefore, relatively safe and unlikely to exacerbate or induce autoimmune diseases. Given its benefits and safety but low coverage, dermatologists and primary care physicians should encourage zoster vaccine use in elderly patients, including selected patients with autoimmune diseases.

This study tested Agnew’s General Strain Theory (GST) by examining the roles of anger, anxiety, and maladaptive coping in mediating the relationship between strain and three outcomes (serious delinquency, minor delinquency, and continued involvement in the juvenile justice system) among adolescent female offenders (N = 261). Strains consisted of adverse life events and exposure to Hurricane Katrina. Greater exposure to Hurricane Katrina was directly related to serious delinquency and maladaptive coping. Hurricane Katrina also had an indirect effect on minor delinquency and Post–Katrina juvenile justice involvement mediated through maladaptive coping. Adverse life events were associated with increased anger, anxiety, and maladaptive coping. Anger mediated the relationship between adverse life events and serious delinquency. Anxiety mediated the relationship between adverse life events and minor delinquency. Maladaptive coping strategies were associated with minor delinquency and juvenile justice involvement. Findings lend support to GST. PMID:21572904

To investigate GPs' attitudes to and willingness to report and learn from adverse events and to study how a reporting system should function. Survey. General practice in Denmark. GPs' attitudes to exchange of experience with colleagues and others, and circumstances under which such exchange is accepted. A structured questionnaire sent to 1198 GPs of whom 61% responded. RESULTS. GPs had a positive attitude towards discussing adverse events in the clinic with colleagues and staff and in their continuing medical education groups. The GPs had a positive attitude to reporting adverse events to a database if the system granted legal and administrative immunity to reporters. The majority preferred a reporting system located at a research institute. GPs have a very positive attitude towards discussing and reporting adverse events. This project encourages further research and pilot projects testing concrete reporting systems.

While preexposure prophylaxis with oral tenofovir/emtricitabine reduces HIV acquisition rates, poor adherence to and acceptability of vaginal gels and the potential for evolving drug resistance have led to development of vaginal film formulations and other antiretroviral drugs, respectively, including the non-nucleoside reverse transcriptase inhibitor dapivirine. In this two-arm crossover study of a novel fast-dissolving dapivirine film and a previously studied semisolid dapivirine gel, 10 healthy women received a single 1.25 mg vaginal dose of each study product; one withdrew after the first dose. Clinical, pharmacokinetic, and antiviral pharmacodynamic assessments (ex vivo HIV-BaL challenge of tissue explants) were performed over 168 h postdose. Six of ten participants experienced mild to moderate adverse effects, similar between products, with no severe adverse events or adverse events attributed to study products. There were no statistically significant differences in plasma, cervicovaginal fluid (CVF), or cervical tissue dapivirine concentrations between the gel and film (all p > .05). CVF dapivirine concentrations were 1.5 and 6 log 10 greater than tissue and plasma concentrations, respectively (p < .001). Both film and gel demonstrated reduced cervical tissue infectivity after ex vivo HIV challenge 5 h postdose, compared to baseline and 72-h postdose biopsies (p < .05 for gel, p = .06 for film). There was no difference in ex vivo explant HIV challenge between gel and film. The dapivirine film and gel performed similarly in terms of tolerability, pharmacokinetics, and antiviral effect. Dapivirine film may provide an alternative to pharmacokinetically comparable dapivirine gel formulations. Effectiveness remains to be tested.

Background Treatment decisions for older patients with type 2 diabetes mellitus must balance glycemic control and adverse event risk. The objective of this study was to evaluate the long-term safety and tolerability of saxagliptin 5 mg as add-on therapy to common antihyperglycemic drugs in patients aged ≥65 years and <65 years. Methods Pooled adverse event data from three placebo-controlled trials of 76–206 weeks’ duration in older (≥65 years) and younger (<65 years) patients receiving saxagliptin 5 mg or matching placebo added to metformin, glyburide, or a thiazolidinedione were analyzed. Measurements were calculated from day of first dose to specified event or last dose and included time at risk for adverse events, treatment-related adverse events, serious adverse events, adverse events leading to discontinuation, and events of special interest. Weighted incidence rates (number of events/total time) and incidence rate ratios (saxagliptin/placebo) with 95% confidence intervals were calculated (Mantel-Haenszel test). Results A total of 205 older (mean age 69 years; saxagliptin, n=99; placebo, n=106) and 1,055 younger (mean age 52 years; saxagliptin, n=531; placebo, n=524) patients were assessed. Regardless of age category, the adverse event incidence rates were generally similar between treatments, with confidence intervals for incidence rate ratios bridging 1. Treatment-related adverse events occurred in 36 older patients receiving saxagliptin versus 32 receiving placebo (incidence rate 34.1 versus 27.1 per 100 person-years) and in 150 younger patients in both treatment groups (incidence rate 24.0 versus 27.8 per 100 person-years). With saxagliptin versus placebo, serious adverse events occurred in eight versus 14 older (incidence rate 5.7 versus 9.9 per 100 person-years) and 49 versus 44 younger patients (incidence rate 6.5 versus 6.6 per 100 person-years). There were two deaths (one patient ≥65 years) with saxagliptin and six (none aged ≥65 years) with placebo. Older patients rarely experienced symptomatic confirmed hypoglycemia (fingerstick glucose ≤50 mg/dL; saxagliptin, n=1; placebo, n=2). Conclusion Saxagliptin add-on therapy was generally well tolerated in older patients aged ≥65 years with type 2 diabetes mellitus, with a long-term safety profile similar to that of placebo.

Epidemiological findings suggest that social involvement plays a major role in establishing resilience to adversity, however, the neurobiology by which social involvement confers protection is not well understood. Hypothesizing that social involvement confers resilience by changing the way adverse life events are encoded, we designed a series of behavioral tests in mice that utilize the presence or absence of conspecific cage mates in measuring response to novel and adverse events. We found that the presence of cage mates increased movement after exposure to a novel environment, increased time spent in the open arms of the elevated plus maze, and decreased freezing time after a foot shock as well as expedited fear extinction, therefore significantly changing the response to adversity. This is a first description of a mouse model for the effects of social involvement on adverse life events. Understanding how social involvement provides resilience to adversity may contribute to the future treatment and prevention of mental and physical illness.

To assess the prevalence of gastrointestinal toxicity in dogs receiving chemotherapy with vincristine and cyclophosphamide and the efficacy of maropitant citrate (Cerenia™, Zoetis) in reducing these events. Dogs receiving chemotherapy with cyclophosphamide or vincristine were randomised to either receive maropitant or not in the period immediately after treatment and for 4 days afterwards. Owners completed a diary of adverse events following treatment. Adverse events occurred in 40/58 (69%) dogs in the vincristine group. Most of these adverse events were mild and included: lethargy (62%), appetite loss (43%), diarrhoea (34%) and vomiting (24%). Adverse events occurred in 34/42 (81%) dogs treated with cyclophosphamide. Most of these adverse events were mild and included: lethargy (62%), diarrhoea (36%), appetite loss (36%) and vomiting (21%). There was no difference in total clinical score, vomiting, diarrhoea, appetite loss or lethargy score between dogs treated with maropitant and non-treated dogs in either the vincristine or cyclophosphamide groups. Chemotherapy-related side effects are frequent but usually mild in dogs receiving vincristine or cyclophosphamide. Prophylactic administration of maropitant does not reduce the frequency of adverse events and maropitant should be administered only as required for individual cases. © 2014 British Small Animal Veterinary Association.

Although the independent effects of childhood adversities and of recent negative events on suicidality have been well-documented, the combinative role of childhood and recent adversities on risk for suicidality is still underexplored, especially in the context of Chinese culture and in consideration of specific types of negative events. 5989 students, randomly sampled from six universities in central China, completed the online survey for this study. Suicidal behavior, life adversity during childhood and stressful events in recent school life were assessed with designed questionnaires. Students experiencing recent stressful life events more often reported an experience of life adversity during childhood. While recent stressful life events and childhood life adversity both were associated with an increased risk for suicidal behavior, the two exposures presented conjunctively and acted interactively to increase the risk. There was noticeable variation of effects associated with specific childhood life adversities, and sexual abuse, poor parental relationship, divorce of parents and loss of a parent were among the adversities associated with the highest increased risk. Recent conflicts with classmates, poor school performance and rupture of romantic relationships were the recent school life stressors associated with the highest increased risk. Childhood adversity and recent school life stressors had a combinative role in predicting suicidality of young people studying in Chinese colleges. Unhappy family life during childhood and recent interpersonal conflicts in school were the most important predictors of suicidality in this population.

The Five A's: what do patients want after an adverse event?
Cox, Wendy
2007-01-01
After an adverse event, Five A's: Acknowledgment, Apology, All the Facts, Assurance and Appropriate Compensation, serve to meet the essential needs of patients and their families. This simple mnemonic creates a clear framework of understanding for the actions health professionals need to take to manage errors and adverse events in an empathic and patient-oriented fashion. While not all patients demand or need compensation, most need at least the first four A's. Patient-centered communication using this simple framework following an adverse event will foster a climate of understanding and frank discussion, addressing the emotional and physical needs of the whole patient and family.

Vaxtracker is a web based survey for active post marketing surveillance of Adverse Events Following Immunisation. It is designed to efficiently monitor vaccine safety of new vaccines by early signal detection of serious adverse events. The Vaxtracker system automates contact with the parents or carers of immunised children by email and/or sms message to their smart phone. A hyperlink on the email and text messages links to a web based survey exploring adverse events following the immunisation. The Vaxtracker concept was developed during 2011 (n=21), and piloted during the 2012 (n=200) and 2013 (n=477) influenza seasons for children receiving inactivated influenza vaccine (IIV) in the Hunter New England Local Health District, New South Wales, Australia. Survey results were reviewed by surveillance staff to detect any safety signals and compare adverse event frequencies among the different influenza vaccines administered. In 2012, 57% (n=113) of the 200 participants responded to the online survey and 61% (290/477) in 2013. Vaxtracker appears to be an effective method for actively monitoring adverse events following influenza vaccination in children. Crown Copyright © 2014. Published by Elsevier Ltd.

The increased morbidity and mortality and poorer quality of life associated with drug-resistant epilepsy justify admitting patients to epilepsy monitoring units (EMU). These units employ methods that promote the occurrence of seizures, which involves a risk of secondary adverse events. The aim of our study is to characterise and quantify these adverse events in a Spanish EMU. A descriptive, longitudinal and retrospective study of patients admitted consecutively to our EMU. Patients admitted due to status epilepticus, clusters of seizures, or as participants in a clinical trial were excluded. We included 175 patients, of whom 92.1% (161) did not suffer any adverse events. Status epilepticus was present in 3.4% (6); 1.7% (3) had traumatic injury, 1.7% (3) had interictal or postictal psychosis, and 1.1% (2) had cardiorespiratory impairment. There were no risk factors associated with these adverse events. The most frequently-identified adverse events were status epilepticus, traumatic injury, interictal or postictal psychosis, and cardiorespiratory disorders. The frequency of these adverse events was similar to that seen in international literature. The complications detected do not contraindicate VEEGM. Copyright © 2012 Sociedad Española de Neurología.

During August-September 2012, the New York City Department of Health and Mental Hygiene (DOHMH) was notified by the New York City Poison Control Center regarding three patients who experienced serious adverse events after anesthesia-assisted rapid opiate detoxification (AAROD) at a local outpatient clinic. All three patients required hospitalization, and one subsequently died. DOHMH issued an order requiring that the clinic cease performing AAROD pending an investigation and searched for additional cases of AAROD-related serious adverse events at the clinic and elsewhere in New York City for the period September 2011 to September 2012. That search found no serious adverse events at clinics other than the one implicated. Of the 75 patients who underwent AAROD at the implicated clinic during January-September 2012, two died, and five others experienced serious adverse events requiring hospitalization. As a result of the findings, the New York State Department of Health, the New York Office of Alcoholism and Substance Abuse Services, and DOHMH jointly issued a Health Alert informing New York health-care providers of AAROD-associated serious adverse events and recommending that they avoid use of AAROD in favor of evidence-based options for opioid dependence treatment.
Methods developed to elucidate nursing related adverse events in Japan.

Financial resources for quality assurance in Japanese hospitals are limited and few hospitals have quality monitoring systems of nursing service systems. However, recently its necessity has been recognized. This study has cost effectively used adverse event occurrence rates as indicators of the quality of nursing service, and audited methods of collecting data on adverse events to elucidate their approximate true numbers. Data collection was conducted in July, August and November 2000 at a hospital in Tokyo that administered both primary and secondary health care services (281 beds, six wards, average length of stay 23 days). We collected adverse events through incident reports, logs, check-lists, nurse interviews, medication error questionnaires, urine leucocyte tests, patient interviews and medical records. Adverse events included the unplanned removals of invasive lines, medication errors, falls, pressure sores, skin deficiencies, physical restraints, and nosocomial infections. After evaluating the time and useful outcomes of each source, it soon became clear that we could elucidate adverse events most consistently and cost-effectively through incident reports, check lists, nurse interviews, urine leucocyte tests and medication error questionnaires. This study suggests that many hospitals in Japan could monitor the quality of the nursing service using these sources.

Patient safety performance can be assessed with several systems, including passive and active surveillance. Passive surveillance systems provide opportunity for health care personnel to confidentially and voluntarily report incidents, including adverse events, occurring in their work environment. Active surveillance systems systematically monitor patient encounters to seek detailed information about adverse events that occur in work environments; unlike passive surveillance, active surveillance allows for collection of both numerator (number of adverse events) and denominator (number of patients seen) data. Chiropractic manual therapy is commonly used in both adults and children, yet few studies have been done to evaluate the safety of chiropractic manual therapy for children. In an attempt to evaluate this, this study will compare adverse event reporting in passive versus active surveillance systems after chiropractic manual therapy in the pediatric population. This cluster randomized controlled trial aims to enroll 70 physicians of chiropractic (unit of randomization) to either passive or active surveillance system to report adverse events that occur after treatment for 60 consecutive pediatric (13 years of age and younger) patient visits (unit of analysis). A modified enrollment process with a two-phase consent procedure will be implemented to maintain provider blinding and minimize dropouts. The first phase of consent is for the provider to confirm their interest in a trial investigating the safety of chiropractic manual therapy. The second phase ensures that they understand the specific requirements for the group to which they were randomized. Percentages, incidence estimates, and 95% confidence intervals will be used to describe the count of reported adverse events in each group. The primary outcome will be the number and quality of the adverse event reports in the active versus the passive surveillance group. With 80% power and 5% one-sided significance level, the sample size was calculated to be 35 providers in each group, which includes an 11% lost to follow-up of chiropractors and 20% of patient visits. This study will be the first direct comparison of adverse event reporting using passive versus active surveillance. It is also the largest prospective evaluation of adverse events reported after chiropractic manual therapy in children, identified as a major gap in the academic literature.

Introduction The potential impact of targeting different components of an adverse lipid profile in populations with multiple cardiovascular risk factors is not completely clear. This study aims to assess the association between different components of the standard lipid profile with all-cause mortality and hospitalization due to cardiovascular events in a high-risk population. Methods This prospective registry included high risk adults over 30 years old free of cardiovascular disease (2008–2012). Diagnosis of hypertension, dyslipidemia or diabetes mellitus was inclusion criterion. Lipid biomarkers were evaluated. Primary endpoints were all-cause mortality and hospital admission due to coronary heart disease or stroke. We estimated adjusted rate ratios (aRR), absolute risk differences and population attributable risk associated with adverse lipid profiles. Results 51,462 subjects were included with a mean age of 62.6 years (47.6% men). During an average follow-up of 3.2 years, 919 deaths, 1666 hospitalizations for coronary heart disease and 1510 hospitalizations for stroke were recorded. The parameters that showed an increased rate for total mortality, coronary heart disease and stroke hospitalization were, respectively, low HDL-Cholesterol: aRR 1.25, 1.29 and 1.23; high Total/HDL-Cholesterol: aRR 1.22, 1.38 and 1.25; and high Triglycerides/HDL-Cholesterol: aRR 1.21, 1.30, 1.09. The parameters that showed highest population attributable risk (%) were, respectively, low HDL-Cholesterol: 7.70, 11.42, 8.40; high Total/HDL-Cholesterol: 6.55, 12.47, 8.73; and high Triglycerides/HDL-Cholesterol: 8.94, 15.09, 6.92. Conclusions In a population with cardiovascular risk factors, HDL-cholesterol, Total/HDL-cholesterol and triglycerides/HDL-cholesterol ratios were associated with a higher population attributable risk for cardiovascular disease compared to other common biomarkers.

Adverse life events have been associated with gambling and substance use as they can serve as forms of escapism. Involvement in gambling and substance use can also place individuals in adversely stressful situations. To explore potential male-female differences in the association between addictive behavior and adverse life events among an urban cohort of adolescents. The study sample comprised of 515 adolescent participants in a randomized prevention trial. With self-reported data, four addictive behavior groups were created: nonsubstance users and nongamblers, substance users only, gamblers only, and substance users and gamblers. Multinomial logistic regression analyses with interaction terms of sex and adverse life events were conducted. Adverse life events and engaging in at least one addictive behavior were common for both sexes. Substance users and gamblers had more than twice the likelihood of nonsubstance users and nongamblers to experience any event as well as events of various domains (ie, relationship, violence, and instability). Neither relationship nor instability events' associations with the co-occurrence of substance use and gambling significantly differed between sexes. Conversely, females exposed to violence events were significantly more likely than similarly exposed males to report the co-occurrence of substance use and gambling. Findings from the current study prompt future studies to devote more attention to the development of effective programs that teach adaptive coping strategies to adolescents, particularly to females upon exposure to violence.

Multiple studies have found that childhood adversity is related to a range of poor mental health, substance abuse, poor physical health, and poor social functioning outcomes in the general population of adults. However, despite the high rates of childhood adversity in schizophrenia, the clinical correlates of these events have not been systematically evaluated. This study evaluated the relationship between adverse experiences in childhood and functional, clinical, and health outcomes among adults with schizophrenia. The authors surveyed 569 adults with schizophrenia regarding adverse childhood events (including physical abuse, sexual abuse, parental mental illnesses, loss of a parent, parental separation or divorce, witnessing domestic violence, and foster or kinship care). The relationships between cumulative exposure to these events and psychiatric, physical, and functional outcomes were evaluated. Increased exposure to adverse childhood events was strongly related to psychiatric problems (suicidal thinking, hospitalizations, distress, and posttraumatic stress disorder), substance abuse, physical health problems (HIV infection), medical service utilization (physician visits), and poor social functioning (homelessness or criminal justice involvement). The findings extend the results of research in the general population by suggesting that childhood adversity contributes to worse mental health, substance abuse, worse physical health, and poor functional outcomes in schizophrenia.
Safety and Effectiveness of Mycophenolate in Systemic Sclerosis. A Systematic Review
2015-01-01
Background Mycophenolate is increasingly being used in the rheumatic diseases. Its main adverse effects are gastrointestinal, myelosuppression, and infection. These may limit use in systemic sclerosis (SSc) since gastrointestinal involvement is common. The objective of this study is to evaluate gastrointestinal adverse events of mycophenolate in SSc. Secondarily we evaluated other adverse events, and the effectiveness of mycophenolate in skin and lung disease. Methods A literature search of Medline, Embase, Cochrane Central Register of Controlled Trials, and CINAHL (inception-2013) was performed. Studies reporting use of mycophenolate in SSc patients, adverse events, modified Rodnan skin score (MRSS), forced vital capacity (FVC), or diffusing capacity of carbon monoxide (DLCO) were included. The primary outcome was gastrointestinal events occurring after the initiation of mycophenolate. Secondary safety outcomes included myelosuppression, infection, malignancy, and death after the initiation of mycophenolate. Results 617 citations were identified and 21 studies were included. 487 patients were exposed to mycophenolate. The mean disease duration ranged between 0.8-14.1 years. There were 18 deaths and 90 non-lethal adverse events. The non-lethal adverse events included 43 (47.7%) gastrointestinal events, 34 (26%) infections, 6 (5%) cytopenias and 2 (2%) malignancies. The most common gastrointestinal events included diarrhea (n=18 (14%)), nausea (n=12 (9%)), and abdominal pain (n=3 (2%)). The rate of discontinuation ranged between 8%-40%. Seven observational studies reported improvement or stabilization in FVC, and 5 studies report stabilization or improvement in MRSS. Conclusion Mycophenolate-associated gastrointestinal adverse events are common in SSc, but not severe enough to preclude its use. Observational data suggests mycophenolate may be effective in improving or stabilizing interstitial lung disease, and skin involvement. PMID:25933090

Preventable adverse events are more likely to occur among older patients because of the clinical complexity of their care. The Veterans Health Administration (VHA) National Center for Patient Safety (NCPS) stores data about serious adverse events when a root cause analysis (RCA) has been performed. A primary objective of this study was to describe the types of adverse events occurring among older patients (age > or = 65 years) in Department of Veterans Affairs (VA) hospitals. Secondary objectives were to determine the underlying reasons for the occurrence of these events and report on effective action plans that have been implemented in VA hospitals. In a retrospective, cross-sectional review, RCA reports were reviewed and outcomes reported using descriptive statistics for all VA hospitals that conducted an RCA for a serious geriatric adverse event from January 2010 to January 2011 that resulted in sustained injury or death. The search produced 325 RCA reports on VA patients (age > or = 65 years). Falls (34.8%), delays in diagnosis and/or treatment (11.7%), unexpected death (9.9%), and medication errors (9.0%) were the most commonly reported adverse events among older VA patients. Communication was the most common underlying reason for these events, representing 43.9% of reported root causes. Approximately 40% of implemented action plans were judged by local staff to be effective. The RCA process identified falls and communication as important themes in serious adverse events. Concrete actions, such as process standardization and changes to communication, were reported by teams to yield some improvement. However, fewer than half of the action plans were reported to be effective. Further research is needed to guide development and implementation of effective action plans.

Dysregulated biological stress systems and adverse life events, independently and in interaction, have been hypothesised to initiate chronic pain. We examine whether (1) function of biological stress systems, (2) adverse life events, and (3) their combination predict the onset of chronic multisite musculoskeletal pain. Subjects (n=2039) of the Netherlands Study of Depression and Anxiety, free from chronic multisite musculoskeletal pain at baseline, were identified using the Chronic Pain Grade Questionnaire and followed up for the onset of chronic multisite musculoskeletal pain over 6 years. Baseline assessment of biological stress systems comprised function of the hypothalamic-pituitary-adrenal axis (1-h cortisol awakening response, evening levels, postdexamethasone levels), the immune system (basal and lipopolysaccharide-stimulated inflammation) and the autonomic nervous system (heart rate, pre-ejection period, SD of the normal-to-normal interval, respiratory sinus arrhythmia). The number of recent adverse life events was assessed at baseline using the List of Threatening Events Questionnaire. Hypothalamic-pituitary-adrenal axis, immune system and autonomic nervous system functioning was not associated with onset of chronic multisite musculoskeletal pain, either by itself or in interaction with adverse life events. Adverse life events did predict onset of chronic multisite musculoskeletal pain (HR per event=1.14, 95% CI 1.04 to 1.24, p=0.005). This longitudinal study could not confirm that dysregulated biological stress systems increase the risk of developing chronic multisite musculoskeletal pain. Adverse life events were a risk factor for the onset of chronic multisite musculoskeletal pain, suggesting that psychosocial factors play a role in triggering the development of this condition.

Biometrical issues in the analysis of adverse events within the benefit assessment of drugs.
Bender, Ralf; Beckmann, Lars; Lange, Stefan
2016-07-01
The analysis of adverse events plays an important role in the benefit assessment of drugs. Consequently, results on adverse events are an integral part of reimbursement dossiers submitted by pharmaceutical companies to health policy decision-makers. Methods applied in the analysis of adverse events commonly include simple standard methods for contingency tables. However, the results produced may be misleading if observations are censored at the time of discontinuation due to treatment switching or noncompliance, resulting in unequal follow-up periods. In this paper, we present examples to show that the application of inadequate methods for the analysis of adverse events in the reimbursement dossier can lead to a downgrading of the evidence on a drug's benefit in the subsequent assessment, as greater harm from the drug cannot be excluded with sufficient certainty. Legal regulations on the benefit assessment of drugs in Germany are presented, in particular, with regard to the analysis of adverse events. Differences in safety considerations between the drug approval process and the benefit assessment are discussed. We show that the naive application of simple proportions in reimbursement dossiers frequently leads to uninterpretable results if observations are censored and the average follow-up periods differ between treatment groups. Likewise, the application of incidence rates may be misleading in the case of recurrent events and unequal follow-up periods. To allow for an appropriate benefit assessment of drugs, adequate survival time methods accounting for time dependencies and duration of follow-up are required, not only for time-to-event efficacy endpoints but also for adverse events. © 2016 The Authors.

The aim of this study was to test for gender differences in how negative cognitive errors (overgeneralizing, catastrophizing, selective abstraction, and personalizing) mediate the association between adverse life events and adolescents' emotional and behavioural problems (measured with the Strengths and Difficulties Questionnaire). The sample consisted of 202 boys and 227 girls (aged 11-15 years) from three state secondary schools in disadvantaged areas in one county in the South East of England. Control variables were age, ethnicity, special educational needs, exclusion history, family structure, family socio-economic disadvantage, and verbal cognitive ability. Adverse life events were measured with Tiet et al.'s (1998) Adverse Life Events Scale. For both genders, we assumed a pathway from adverse life events to emotional and behavioural problems via cognitive errors. We found no gender differences in life adversity, cognitive errors, total difficulties, peer problems, or hyperactivity. In both boys and girls, even after adjustment for controls, cognitive errors were related to total difficulties and emotional symptoms, and life adversity was related to total difficulties and conduct problems. The life adversity/conduct problems association was not explained by negative cognitive errors in either gender. However, we found gender differences in how adversity and cognitive errors produced hyperactivity and internalizing problems. In particular, life adversity was not related, after adjustment for controls, to hyperactivity in girls and to peer problems and emotional symptoms in boys. Cognitive errors fully mediated the effect of life adversity on hyperactivity in boys and on peer and emotional problems in girls.

We investigated the relationship between axitinib pharmacogenetics and clinical efficacy/adverse events in advanced renal cell carcinoma (RCC) and established a model to predict clinical efficacy and adverse events using pharmacokinetic and gene polymorphisms related to drug metabolism and efflux in a phase II trial. We prospectively evaluated the area under the plasma concentration-time curve (AUC) of axitinib, objective response rate, and adverse events in 44 consecutive advanced RCC patients treated with axitinib. To establish a model for predicting clinical efficacy and adverse events, polymorphisms in genes including ABC transporters ( ABCB1 and ABCG2 ), UGT1A , and OR2B11 were analyzed by whole-exome sequencing, Sanger sequencing, and DNA microarray. To validate this prediction model, calculated AUC by 6 gene polymorphisms was compared with actual AUC in 16 additional consecutive patients prospectively. Actual AUC significantly correlated with the objective response rate ( P = 0.0002) and adverse events (hand-foot syndrome, P = 0.0055; and hypothyroidism, P = 0.0381). Calculated AUC significantly correlated with actual AUC ( P < 0.0001), and correctly predicted objective response rate ( P = 0.0044) as well as adverse events ( P = 0.0191 and 0.0082, respectively). In the validation study, calculated AUC prior to axitinib treatment precisely predicted actual AUC after axitinib treatment ( P = 0.0066). Our pharmacogenetics-based AUC prediction model may determine the optimal initial dose of axitinib, and thus facilitate better treatment of patients with advanced RCC.

We investigated the relationship between axitinib pharmacogenetics and clinical efficacy/adverse events in advanced renal cell carcinoma (RCC) and established a model to predict clinical efficacy and adverse events using pharmacokinetic and gene polymorphisms related to drug metabolism and efflux in a phase II trial. We prospectively evaluated the area under the plasma concentration–time curve (AUC) of axitinib, objective response rate, and adverse events in 44 consecutive advanced RCC patients treated with axitinib. To establish a model for predicting clinical efficacy and adverse events, polymorphisms in genes including ABC transporters (ABCB1 and ABCG2), UGT1A, and OR2B11 were analyzed by whole-exome sequencing, Sanger sequencing, and DNA microarray. To validate this prediction model, calculated AUC by 6 gene polymorphisms was compared with actual AUC in 16 additional consecutive patients prospectively. Actual AUC significantly correlated with the objective response rate (P = 0.0002) and adverse events (hand-foot syndrome, P = 0.0055; and hypothyroidism, P = 0.0381). Calculated AUC significantly correlated with actual AUC (P < 0.0001), and correctly predicted objective response rate (P = 0.0044) as well as adverse events (P = 0.0191 and 0.0082, respectively). In the validation study, calculated AUC prior to axitinib treatment precisely predicted actual AUC after axitinib treatment (P = 0.0066). Our pharmacogenetics-based AUC prediction model may determine the optimal initial dose of axitinib, and thus facilitate better treatment of patients with advanced RCC. PMID:29682213

Physical activity has established mental and physical health benefits, but related adverse events have not received attention. The purpose of this paper was to review the documented adverse events occurring from physical activity participation among individuals with psychological or cognitive conditions. Literature was identified through electronic database (e.g., MEDLINE, psychINFO) searching. Studies were eligible if they described a published paper examining the effect of changes on physical activity behaviour, included a diagnosed population with a cognitive or psychological disorder, and reported on the presence or absence of adverse events. Quality of included studies was assessed, and the analyses examined the overall evidence by available subcategories. Forty trials passed the eligibility criteria; these were grouped (not mutually exclusively) by dementia (n = 5), depression (n = 10), anxiety disorders (n = 12), eating disorders (n = 4), psychotic disorders (n = 4), and intellectual disability (n = 15). All studies displayed a possible risk of bias, ranging from moderate to high. The results showed a relatively low prevalence of adverse events. Populations with dementia, psychological disorders, or intellectual disability do not report considerable or consequential adverse events from physical activity independent of associated comorbidities. The one exception to these findings may be Down syndrome populations with atlantoaxial instability; in these cases, additional caution may be required during screening for physical activity. This review, however, highlights the relative paucity of the reported presence or absence of adverse events, and finds that many studies are at high risk of bias toward reporting naturally occurring adverse events.

Composite disease burden measures such as disability-adjusted life-years (DALY) have been widely used to quantify the population-level health impact of disease or injury, but application has been limited for the estimation of the burden of adverse events following immunization. Our objective was to assess the feasibility of adapting the DALY approach for estimating adverse event burden. We developed a practical methodological framework, explicitly describing all steps involved: acquisition of relative or absolute risks and background event incidence rates, selection of disability weights and durations, and computation of the years lived with disability (YLD) measure, with appropriate estimation of uncertainty. We present a worked example, in which YLD is computed for 3 recognized adverse reactions following 3 childhood vaccination types, based on background incidence rates and relative/absolute risks retrieved from the literature. YLD provided extra insight into the health impact of an adverse event over presentation of incidence rates only, as severity and duration are additionally incorporated. As well as providing guidance for the deployment of DALY methodology in the context of adverse events associated with vaccination, we also identified where data limitations potentially occur. Burden of disease methodology can be applied to estimate the health burden of adverse events following vaccination in a systematic way. As with all burden of disease studies, interpretation of the estimates must consider the quality and accuracy of the data sources contributing to the DALY computation. © 2018 The Authors.

Medication errors: the role of the patient.
Britten, Nicky
2009-06-01
1. Patients and their carers will usually be the first to notice any observable problems resulting from medication errors. They will probably be unable to distinguish between medication errors, adverse drug reactions, or 'side effects'. 2. Little is known about how patients understand drug related problems or how they make attributions of adverse effects. Some research suggests that patients' cognitive models of adverse drug reactions bear a close relationship to models of illness perception. 3. Attributions of adverse drug reactions are related to people's previous experiences and to their level of education. The evidence suggests that on the whole patients' reports of adverse drug reactions are accurate. However, patients do not report all the problems they perceive and are more likely to report those that they do perceive as severe. Patients may not report problems attributed to their medications if they are fearful of doctors' reactions. Doctors may respond inappropriately to patients' concerns, for example by ignoring them. Some authors have proposed the use of a symptom checklist to elicit patients' reports of suspected adverse drug reactions. 4. Many patients want information about adverse drug effects, and the challenge for the professional is to judge how much information to provide and the best way of doing so. Professionals' inappropriate emphasis on adherence may be dangerous when a medication error has occurred. 5. Recent NICE guidelines recommend that professionals should ask patients if they have any concerns about their medicines, and this approach is likely to yield information conducive to the identification of medication errors.

Eslicarbazepine acetate was first approved in the European Union in 2009 as adjunctive therapy in adults with partial-onset seizures with or without secondary generalization. The objective of this study was to review the safety profile of eslicarbazepine acetate analyzing the data from several clinical studies to 6 years of post-marketing surveillance. We used a post-hoc pooled safety analysis of four phase III, double-blind, randomized, placebo-controlled studies (BIA-2093-301, -302, -303, -304) of eslicarbazepine acetate as add-on therapy in adults. Safety data of eslicarbazepine acetate in special populations of patients aged ≥65 years with partial-onset seizures (BIA-2093-401) and subjects with moderate hepatic impairment (BIA-2093-111) and renal impairment (BIA-2093-112) are also considered. The incidences of treatment-emergent adverse events, treatment-emergent adverse events leading to discontinuation, and serious adverse events were analyzed. The global safety database of eslicarbazepine acetate was analyzed for all cases from post-marketing surveillance from 1 October, 2009 to 21 October, 2015. From a pooled analysis of four phase III studies, it was concluded that the incidence of treatment-emergent adverse events, treatment-emergent adverse events leading to discontinuation, and adverse drug reactions were dose dependent. Dizziness, somnolence, headache, and nausea were the most common treatment-emergent adverse events (≥10% of patients) and the majority were of mild-to-moderate intensity. No dose-dependent trend was observed for serious adverse events and individual serious adverse events were reported in less than 1% of patients. Hyponatremia was classified as a possibly related treatment-emergent adverse event in phase III studies (1.2%); however, after 6 years of post-marketing surveillance it represents the most frequently (10.2%) reported adverse drug reaction, with more than half of these cases occurring with eslicarbazepine acetate at daily doses of 1200 mg. Other adverse drug reactions reported in post-marketing surveillance are seizure (5.8%), dizziness (4.1%), rash (2.6%), and fatigue (2.1%). The safety profile of eslicarbazepine acetate in renal and hepatic impairment subjects (phase I studies) and in elderly patients (phase III study) did not raise any specific concern. After 6 years of post-marketing surveillance, eslicarbazepine acetate maintains a similar safety profile to that observed in pivotal clinical studies.

This paper describes the results of an independent analysis of the probable and contributory causes of selected aviation accidents in the United States between 1996 and 2003. The purpose of the study was to assess the comparative frequency of a variety of causal factors in the reporting of these adverse events. Although our results show that more of these high consequence accidents were attributed to human error than to any other single factor, a large number of reports also mentioned wider systemic issues, including the managerial and regulatory context of aviation operations. These wider issues are more likely to appear as contributory rather than primary causes in this set of accident reports.

To identify safety signals by manual review of individual report in large surveillance databases is time consuming; such an approach is very unlikely to reveal complex relationships between medications and adverse events. Since the late 1990s, efforts have been made to develop data mining tools to systematically and automatically search for safety signals in surveillance databases. Influenza vaccines present special challenges to safety surveillance because the vaccine changes every year in response to the influenza strains predicted to be prevalent that year. Therefore, it may be expected that reporting rates of adverse events following flu vaccines (number of reports for a specific vaccine-event combination/number of reports for all vaccine-event combinations) may vary substantially across reporting years. Current surveillance methods seldom consider these variations in signal detection, and reports from different years are typically collapsed together to conduct safety analyses. However, merging reports from different years ignores the potential heterogeneity of reporting rates across years and may miss important safety signals. Reports of adverse events between years 1990 to 2013 were extracted from the Vaccine Adverse Event Reporting System (VAERS) database and formatted into a three-dimensional data array with types of vaccine, groups of adverse events and reporting time as the three dimensions. We propose a random effects model to test the heterogeneity of reporting rates for a given vaccine-event combination across reporting years. The proposed method provides a rigorous statistical procedure to detect differences of reporting rates among years. We also introduce a new visualization tool to summarize the result of the proposed method when applied to multiple vaccine-adverse event combinations. We applied the proposed method to detect safety signals of FLU3, an influenza vaccine containing three flu strains, in the VAERS database. We showed that it had high statistical power to detect the variation in reporting rates across years. The identified vaccine-event combinations with significant different reporting rates over years suggested potential safety issues due to changes in vaccines which require further investigation. We developed a statistical model to detect safety signals arising from heterogeneity of reporting rates of a given vaccine-event combinations across reporting years. This method detects variation in reporting rates over years with high power. The temporal trend of reporting rate across years may reveal the impact of vaccine update on occurrence of adverse events and provide evidence for further investigations.

Percutaneous closure of patent foramen ovale/atrial septal defect (PFO/ASD) is an increasingly common procedure perceived as having minimal risk. There are no population-based estimates of in-hospital adverse event rates of percutaneous PFO/ASD closure. We used nationally representative data from the 2001-2005 Nationwide Inpatient Sample to identify patients >or-=20 years old admitted to an acute care hospital with an International Classification of Diseases, Ninth Revision code designating percutaneous PFO/ASD closure on the first or second hospital day. Variables analyzed included age, sex, number of comorbidities, year, same-day use of intracardiac or other echocardiography, same-day left heart catheterization, hospital size and teaching status, PFO/ASD procedural volume, and coronary intervention volume. Outcomes of interest included length of stay, charges, and adverse events. The study included 2,555 (weighted to United States population: 12,544 +/- 1,987) PFO/ASD closure procedures. Mean age was 52.0 +/- 0.4 years, and 57.3% +/- 1.0% were women. Annual hospital volume averaged 40.8 +/- 7.7 procedures (range, 1-114). Overall, 8.2 +/- 0.8% of admissions involved an adverse event. Older patients and those with comorbidities were more likely to sustain adverse events. Use of intracardiac echocardiography was associated with fewer adverse events. The risk of adverse events was inversely proportional to annual hospital volume (odds ratio [OR] 0.91, 95% confidence interval [CI] 0.86-0.96, per 10 procedures), even after limiting the analysis to hospitals performing >or=10 procedures annually (OR 0.91, 95% CI 0.85-0.98). Adverse events were more frequent at hospitals in the lowest volume quintile as compared with the highest volume quintile (13.3% vs 5.4%, OR 2.42, 95% CI 1.55-3.78). The risk of adverse events of percutaneous PFO/ASD closure is inversely correlated with hospital volume. This relationship applies even to hospitals meeting the current guidelines, performing >or=10 procedures annually.

We have previously reported an association between childhood abuse and psychotic experiences (PEs) in survey data from South East London. Childhood abuse is related to subsequent adulthood adversity, which could form one pathway to PEs. We aimed to investigate evidence of mediation of the association between childhood abuse and PEs by adverse life events. Data were analysed from the South East London Community Health Study (SELCoH, n = 1698). Estimates of the total effects on PEs of any physical or sexual abuse while growing up were partitioned into direct (i.e. unmediated) and indirect (total and specific) effects, mediated via violent and non-violent life events. There was strong statistical evidence for direct (OR 1.58, 95% CI: 1.19-2.1) and indirect (OR 1.51, 95% CI: 1.32-1.72) effects of childhood abuse on PEs after adjustment for potential confounders, indicating partial mediation of this effect via violent and non-violent life events. An estimated 47% of the total effect of abuse on PEs was mediated via adulthood adverse life events, of which violent life events made up 33% and non-violent life events the remaining 14%. The association between childhood abuse and PEs is partly mediated through the experience of adverse life events in adulthood. There is some evidence that a larger proportion of this effect was mediated through violent life events than non-violent life events.

The fish early-life stage (FELS) test (Organisation for Economic Co-operation and Development [OECD] test guideline 210) is the primary test used internationally to estimate chronic fish toxicity in support of ecological risk assessments and chemical management programs. As part of an ongoing effort to develop efficient and cost-effective alternatives to the FELS test, there is a need to identify and describe potential adverse outcome pathways (AOPs) relevant to FELS toxicity. To support this endeavor, the authors outline and illustrate an overall strategy for the discovery and annotation of FELS AOPs. Key events represented by major developmental landmarks were organized into a preliminary conceptual model of fish development. Using swim bladder inflation as an example, a weight-of-evidence–based approach was used to support linkage of key molecular initiating events to adverse phenotypic outcomes and reduced young-of-year survival. Based on an iterative approach, the feasibility of using key events as the foundation for expanding a network of plausible linkages and AOP knowledge was explored and, in the process, important knowledge gaps were identified. Given the scope and scale of the task, prioritization of AOP development was recommended and key research objectives were defined relative to factors such as current animal-use restrictions in the European Union and increased demands for fish toxicity data in chemical management programs globally. The example and strategy described are intended to guide collective efforts to define FELS-related AOPs and develop resource-efficient predictive assays that address the toxicological domain of the OECD 210 test.

OBJECTIVES—The primary objective was to investigate the safety of recombinant human granulocyte colony stimulating factor (rhG-CSF) for the treatment of very low birthweight infants (VLBW) with sepsis and relative neutropenia, specifically with regard to worsening of respiratory distress and thrombocytopenia and all cause mortality. Secondary objectives were to evaluate duration of ventilation, intensive care, and antibiotic use as markers of efficacy. DESIGN—Neonates (⩽ 28 days) in intensive care, with birth weights of 500-1500 g, absolute neutrophil count (ANC) of ⩽ 5 × 109/l, and clinical evidence of sepsis, were randomly assigned to receive either rhG-CSF (10 µg/kg/day) administered intravenously (n = 13), or placebo (n = 15) for a maximum of 14 days, in addition to standard treatment and antibiotics. All adverse events, oxygenation index, incidence of thrombocytopenia, all cause mortality, duration of ventilation, intensive care and antibiotic treatment, and ANC recovery were compared between the two groups. RESULTS—Adverse events and oxygenation index were not increased by, and thrombocytopenia was not attributable to, treatment with rhG-CSF. At 6 and 12 months postmenstrual age, there were significantly fewer deaths in the group receiving rhG-CSF (1/13 v 7/15; p ⩽ 0.038). There was a non-significant trend towards a reduction in duration of ventilation, intensive care, and antibiotic use in the rhG-CSF group. There was a significantly more rapid increase in ANC in the rhG-CSF treated babies (p < 0.001). CONCLUSIONS—In a small randomised placebo controlled trial in a highly selected group of neonates, adjuvant treatment with rhG-CSF increased ANC rapidly, and no treatment related adverse events were identified. Mortality at 6 and 12 months postmenstrual age was significantly lower in the treatment group. A large trial investigating efficacy in a similar group of neonates is warranted. PMID:11320043

Paraquat poisoning causes multiple organ injury and high mortality due to severe toxicity and lack of effective treatment. Xuebijing (XBJ) injection, a traditional Chinese medicine preparation of five Chinese herbs (Radix Salviae Miltiorrhiae, Rhizoma Chuanxiong, Flos Carthami, Angelica Sinensis and Radix Paeoniae Rubra), has an anti-inflammatory effect and is widely used in the treatment of sepsis. This retrospective study was designed to evaluate the effects of XBJ combined with conventional therapy on mortality risk of patients with acute paraquat poisoning. Out of 68 patients, 27 were treated with conventional therapy (control group) and 41 were treated with intravenous administration of XBJ (100 ml, twice a day, up to 7 days) plus conventional therapy (XBJ group). Vital organ function, survival time within 28 days and adverse events during the treatment were reviewed. Results indicated that XBJ treatment significantly increased median survival time among patients ingesting 10-30 ml of paraquat (P=0.02) compared with the control group. After adjustment for covariates, XBJ treatment was associated significantly with a lower mortality risk (adjusted HR 0.242, 95% CI 0.113 to 0.516, P=0.001) compared with the control group. Additionally, compared with Day 1, on Day 3 the value of PaO2/FiO2 was significantly decreased, and the values of serum alanine aminotransferase, creatinine and troponin T were significantly increased in the control group (all P<0.05), but these values were significant improved in the XBJ group (all P<0.05). Only one patient had skin rash with itch within 30 minutes after injection and no severe adverse events were found in the XBJ group. In conclusion, XBJ treatment is associated with decreased mortality risk of patients with moderate paraquat poisoning, which may be attributed to improved function of vital organs with no severe adverse events.

The aim of this study was to compare the effectiveness of a femoral nerve block and a periarticular infiltration in the management of early post-operative pain after total knee arthroplasty (TKA). A pragmatic, single centre, two arm parallel group, patient blinded, randomised controlled trial was undertaken. All patients due for TKA were eligible. Exclusion criteria included contraindications to the medications involved in the study and patients with a neurological abnormality of the lower limb. Patients received either a femoral nerve block with 75 mg of 0.25% levobupivacaine hydrochloride around the nerve, or periarticular infiltration with 150 mg of 0.25% levobupivacaine hydrochloride, 10 mg morphine sulphate, 30 mg ketorolac trometamol and 0.25 mg of adrenaline all diluted with 0.9% saline to make a volume of 150 ml. A total of 264 patients were recruited and data from 230 (88%) were available for the primary analysis. Intention-to-treat analysis of the primary outcome measure of a visual analogue score for pain on the first post-operative day, prior to physiotherapy, was similar in both groups. The mean difference was -0.7 (95% confidence interval (CI) -5.9 to 4.5; p = 0.834). The periarticular group used less morphine in the first post-operative day compared with the femoral nerve block group (74%, 95% CI 55 to 99). The femoral nerve block group reported 39 adverse events, of which 27 were serious, in 31 patients and the periarticular group reported 51 adverse events, of which 38 were serious, in 42 patients up to six weeks post-operatively. None of the adverse events were directly attributed to either of the interventions under investigation. Periarticular infiltration is a viable and safe alternative to femoral nerve block for the early post-operative relief of pain following TKA.

This article critically reviews HPV vaccine serious adverse events described in pre-licensure randomized trials and in post-marketing case series. HPV vaccine randomized trials were identified in PubMed. Safety data were extracted. Post-marketing case series describing HPV immunization adverse events were reviewed. Most HPV vaccine randomized trials did not use inert placebo in the control group. Two of the largest randomized trials found significantly more severe adverse events in the tested HPV vaccine arm of the study. Compared to 2871 women receiving aluminum placebo, the group of 2881 women injected with the bivalent HPV vaccine had more deaths on follow-up (14 vs. 3, p = 0.012). Compared to 7078 girls injected with the 4-valent HPV vaccine, 7071 girls receiving the 9-valent dose had more serious systemic adverse events (3.3 vs. 2.6%, p = 0.01). For the 9-valent dose, our calculated number needed to seriously harm is 140 (95% CI, 79–653) [DOSAGE ERROR CORRECTED] . The number needed to vaccinate is 1757 (95% CI, 131 to infinity). Practically, none of the serious adverse events occurring in any arm of both studies were judged to be vaccine-related. Pre-clinical trials, post-marketing case series, and the global drug adverse reaction database (VigiBase) describe similar post-HPV immunization symptom clusters. Two of the largest randomized HPV vaccine trials unveiled more severe adverse events in the tested HPV vaccine arm of the study. Nine-valent HPV vaccine has a worrisome number needed to vaccinate/number needed to harm quotient. Pre-clinical trials and post-marketing case series describe similar post-HPV immunization symptoms.

To examine whether persons who experienced adverse childhood events or recent negative life events have a worse cognitive performance and faster cognitive decline and the role of depression and apolipoprotein E-∊4 in this relationship. The community-based sample consisted of 10-year follow-up data of 1312 persons participating in the Longitudinal Aging Study Amsterdam (age range 65-85 years). Persons who experienced adverse childhood events showed a faster 10-year decline in processing speed but only when depressive symptoms were experienced. Persons with more recent negative life events showed slower processing speed at baseline but no faster decline. Childhood adversity may cause biological or psychological vulnerability, which is associated with both depressive symptoms and cognitive decline in later life. The accumulation of recent negative life events did not affect cognitive functioning over a longer time period. © The Author(s) 2014.

Attribution of extreme weather events has recently generated a lot of interest simultaneously within the general public, the scientific community, and stakeholders affected by meteorological extremes. This interest calls for the need to explore the potential convergence of the current atttribution science with the desire and needs of stakeholders. Such an euiry contributes to the development of climate services aiming at quantifying the human responsibility for particular events. Through interviews with climate scientists, through the analysis of the press coverage of extreme meteorological events, and through stakeholder (private sector, covernment services and local and regional government) focus groups, we analyze how social representations of the concepts associated with extreme event attribution are theorized. From the corpuses generated in the course of this enquiry, we build up a grounded, bottom-up, theorization of extreme weather event attribution. This bottom-up theorization allows for a framing of the potential climate services in a way that is attuned to the needs and expectations of the stakeholders. From apparently simple formulations: "what is an extreme event?", "what makes it extreme?", "what is meant by attribution of extreme weather events?", "what do we want to attribute?", "what is a climate service?", we demonstrate the polysemy of these terms and propose ways to address the challenges associated with the juxtaposition of four highly loaded concepts: extreme - event - attribution - climate services.

We examined the effects of the black box warning about the risk of tardive dyskinesia (TD) with chronic use of metoclopramide on management of gastroparesis within a single clinical practice, and on reporting of adverse events. Medical records of gastroparesis patients were evaluated for physician management choices. The FDA Adverse Event Reporting System (FAERS) was analyzed for event reports, and for lawyer-initiated reports, with metoclopramide from 2004 to 2010. Google Scholar was searched for court opinions against metoclopramide manufacturers. Before the black box warning, 69.8% of patients received metoclopramide for gastroparesis, compared with 23.7% after the warning. Gastroenterologists prescribed domperidone more often after than before the warning. Metoclopramide prescriptions decreased after 2008. Adverse event reporting increased after the warning. Only 3.6% of all FAERS reports but 70% of TD reports were filed by lawyers, suggesting a distortion in signal. Forty-seven legal opinions were identified, 33 from 2009-2010. The black box warning for metoclopramide has decreased its usage and increased its rate of adverse event reporting. Lawyer-initiated reports of TD hinder pharmacovigilance.

Social media offer insights of patients' medical problems such as drug side effects and treatment failures. Patient reports of adverse drug events from social media have great potential to improve current practice of pharmacovigilance. However, extracting patient adverse drug event reports from social media continues to be an important challenge for health informatics research. In this study, we develop a research framework with advanced natural language processing techniques for integrated and high-performance patient reported adverse drug event extraction. The framework consists of medical entity extraction for recognizing patient discussions of drug and events, adverse drug event extraction with shortest dependency path kernel based statistical learning method and semantic filtering with information from medical knowledge bases, and report source classification to tease out noise. To evaluate the proposed framework, a series of experiments were conducted on a test bed encompassing about postings from major diabetes and heart disease forums in the United States. The results reveal that each component of the framework significantly contributes to its overall effectiveness. Our framework significantly outperforms prior work. Published by Elsevier Inc.
Detecting and Attributing Health Burdens to Climate Change.
Ebi, Kristie L; Ogden, Nicholas H; Semenza, Jan C; Woodward, Alistair

Detection and attribution of health impacts caused by climate change uses formal methods to determine a ) whether the occurrence of adverse health outcomes has changed, and b ) the extent to which that change could be attributed to climate change. There have been limited efforts to undertake detection and attribution analyses in health. Our goal was to show a range of approaches for conducting detection and attribution analyses. Case studies for heatwaves, Lyme disease in Canada, and Vibrio emergence in northern Europe highlight evidence that climate change is adversely affecting human health. Changes in rates and geographic distribution of adverse health outcomes were detected, and, in each instance, a proportion of the observed changes could, in our judgment, be attributed to changes in weather patterns associated with climate change. The results of detection and attribution studies can inform evidence-based risk management to reduce current, and plan for future, changes in health risks associated with climate change. Gaining a better understanding of the size, timing, and distribution of the climate change burden of disease and injury requires reliable long-term data sets, more knowledge about the factors that confound and modify the effects of climate on health, and refinement of analytic techniques for detection and attribution. At the same time, significant advances are possible in the absence of complete data and statistical certainty: there is a place for well-informed judgments, based on understanding of underlying processes and matching of patterns of health, climate, and other determinants of human well-being. https://doi.org/10.1289/EHP1509.
Adverse Outcome Pathways: From Research to Regulation - Scientific Workshop Report

Patient-identified events implicated in the development of body dysmorphic disorder.
Weingarden, Hilary; Curley, Erin E; Renshaw, Keith D; Wilhelm, Sabine
2017-06-01
Little is known about the causes of body dysmorphic disorder (BDD), but researchers have proposed a diathesis-stress model. This study uses a patient-centered approach to identify stressful events to which patients attribute the development of their BDD symptoms. An Internet-recruited sample of 165 adults with BDD participated. A large minority of participants attributed the development of their BDD to a triggering event. Bullying experiences were the most commonly described type of event. Additionally, most events were interpersonal and occurred during grade school or middle school. There were no differences in severity of psychosocial outcomes between participants who did or did not attribute their BDD to a specific triggering event. However, participants who specifically attributed their BDD development to a bullying experience had poorer psychosocial outcomes (i.e., perceived social support, depression severity, functional impairment, quality of life) compared to those who attributed their BDD development to another type of triggering event.

You, Zhiqi; Chen, Mingxi; Yang, Sen; Zhou, Zongkui; Qin, Ping
2014-01-01
Background Although the independent effects of childhood adversities and of recent negative events on suicidality have been well-documented, the combinative role of childhood and recent adversities on risk for suicidality is still underexplored, especially in the context of Chinese culture and in consideration of specific types of negative events. Method 5989 students, randomly sampled from six universities in central China, completed the online survey for this study. Suicidal behavior, life adversity during childhood and stressful events in recent school life were assessed with designed questionnaires. Results Students experiencing recent stressful life events more often reported an experience of life adversity during childhood. While recent stressful life events and childhood life adversity both were associated with an increased risk for suicidal behavior, the two exposures presented conjunctively and acted interactively to increase the risk. There was noticeable variation of effects associated with specific childhood life adversities, and sexual abuse, poor parental relationship, divorce of parents and loss of a parent were among the adversities associated with the highest increased risk. Recent conflicts with classmates, poor school performance and rupture of romantic relationships were the recent school life stressors associated with the highest increased risk. Conclusions Childhood adversity and recent school life stressors had a combinative role in predicting suicidality of young people studying in Chinese colleges. Unhappy family life during childhood and recent interpersonal conflicts in school were the most important predictors of suicidality in this population. PMID:24681891
Association between Adverse Life Events and Addictive Behaviors among Male and Female Adolescents
Lee, Grace P.; Storr, Carla L.; Ialongo, Nicholas S.; Martins, Silvia S.

Background Adverse life events have been associated with gambling and substance use as they can serve as forms of escapism. Involvement in gambling and substance use can also place individuals in adversely stressful situations. Objectives To explore potential male-female differences in the association between addictive behavior and adverse life events among an urban cohort of adolescents. Methods The study sample comprised of 515 adolescent participants in a randomized prevention trial. With self-reported data, four addictive behavior groups were created: Non-Substance Users and Non-Gamblers, Substance Users Only, Gamblers Only, and Substance Users and Gamblers. Multinomial logistic regression analyses with interaction terms of sex and adverse life events were conducted. Results Adverse life events and engaging in at least one addictive behavior were common for both sexes. Substance Users and Gamblers had more than twice the likelihood of Non-Substance Users and Non-Gamblers to experience any event as well as events of various domains (i.e., relationship, violence, and instability). Neither relationship nor instability events’ associations with the co-occurrence of substance use and gambling significantly differed between sexes. Conversely, females exposed to violence events were significantly more likely than similarly exposed males to report the co-occurrence of substance use and gambling. Conclusion Findings from the current study prompt future studies to devote more attention to the development of effective programs that teach adaptive coping strategies to adolescents, particularly to females upon exposure to violence.

Objective To analyze rates of significant adverse events and outcomes in women having a medical abortion at Planned Parenthood health centers in 2009 and 2010, and to identify changes in the rates of adverse events and outcomes between the 2 years. Methods In this database review we analyzed data from Planned Parenthood affiliates that provided medical abortion in 2009 and 2010, almost exclusively using an evidence-based buccal misoprostol regimen. We evaluated the incidence of six clinically significant adverse events (hospital admission, blood transfusion, emergency room treatment, intravenous antibiotics administration, infection, and death) and two significant outcomes (ongoing pregnancy and ectopic pregnancy diagnosed after medical abortion treatment was initiated). We calculated an overall rate as well as rates for each event and identified changes between the 2 years. Results Amongst 233,805 medical abortions provided in 2009 and 2010, significant adverse events or outcomes were reported in 1,530 cases (0.65%). There was no statistically significant difference in overall rates between years. The most common significant outcome was ongoing intrauterine pregnancy (0.50%); significant adverse events occurred in 0.16% of cases. One patient death occurred due to an undiagnosed ectopic pregnancy. Only rates for emergency room treatment and blood transfusion differed by year, and were slightly higher in 2010. Conclusion Review of this large dataset reinforces the safety of the evidence-based medical abortion regimen. PMID:23262942

Revisiting the relationship between attributional style and academic performance
2015-01-01
Abstract Previous research into the relationship between attributions and academic performance has produced contradictory findings that have not been resolved. The present research examines the role of specific dimensions of attributional style in predicting subsequent academic performance in a sample of pupils (N = 979) from both high‐ and low‐achieving schools. Hierarchical regression and moderation analyses indicate that internal, stable, and global, attributional styles for positive events predict higher levels of academic performance. Global attributions for negative events were related to poorer performance across all schools. Stable attributions for negative events were related to higher levels of performance in high‐achieving schools but not in low‐achieving schools. Higher levels of internality for negative events were associated with higher performance only in low achieving schools. PMID:27594711

We performed a retrospective study in patients with poorly controlled epilepsy treated with add-on lacosamide (LCM) to investigate the relationship of LCM-related adverse events with LCM serum concentration and weight-dependent dosage. We collected serum concentrations, weight-related dosages, and occurrences of the seven most frequent adverse events according to the randomized double-blind, placebo-controlled trials. Seventy of 131 patients could be sufficiently evaluated. LCM serum concentrations and weight-related dosages in patients with and without typical adverse events did not differ significantly. Closer analysis of the data suggested that dizziness as the leading adverse event occurred significantly more often if LCM was combined with classic sodium channel blockers. There was a significant correlation between LCM serum concentrations and co-medication, so there is still evidence for dependent variables that might have a relevant impact in individual cases. However, our data do not allow definition of a safety range for LCM. Copyright © 2011 Elsevier Inc. All rights reserved.
PD-1 checkpoint inhibition: Toxicities and management.
Hahn, Andrew W; Gill, David M; Agarwal, Neeraj; Maughan, Benjamin L
2017-12-01
With the recent approval of 5 PD-1/PD-L1 inhibitors for a number of malignancies, PD-1 axis inhibition is drastically changing the treatment landscape of immunotherapy in cancer. As PD-1/PD-L1 are involved in peripheral immune tolerance, inhibition of this immune checkpoint has led to novel immune-related adverse events including colitis, hepatitis, pneumonitis, rash, and endocrinopathies among many others. In this seminar, we will analyze the incidence of immune-related adverse events for nivolumab, pembrolizumab, atezolizumab, durvalumab, and avelumab. Then, we will discuss the specific management of the most common immune-mediated adverse events including colitis, hepatitis, pneumonitis, rash, endocrinopathies, nephritis, and neurologic toxicities. Immune-related adverse events are frequently treated with immunosuppressive medication such as steroids and mycofenolate mofetil. There are specific immune-related adverse events which are frequently seen by the treating oncologist from checkpoint inhibitors. It is essential to understand the recommended treatment options to minimize toxicity and mortality from this important class of anti-neoplastic therapies. Copyright © 2017 Elsevier Inc.

Proposal of a trigger tool to assess adverse events in dental care.
Corrêa, Claudia Dolores Trierweiler Sampaio de Oliveira; Mendes, Walter
2017-11-21
The aim of this study was to propose a trigger tool for research of adverse events in outpatient dentistry in Brazil. The tool was elaborated in two stages: (i) to build a preliminary set of triggers, a literature review was conducted to identify the composition of trigger tools used in other areas of health and the principal adverse events found in dentistry; (ii) to validate the preliminarily constructed triggers a panel of experts was organized using the modified Delphi method. Fourteen triggers were elaborated in a tool with explicit criteria to identify potential adverse events in dental care, essential for retrospective patient chart reviews. Studies on patient safety in dental care are still incipient when compared to other areas of health care. This study intended to contribute to the research in this field. The contribution by the literature and guidance from the expert panel allowed elaborating a set of triggers to detect adverse events in dental care, but additional studies are needed to test the instrument's validity.

Evaluating medications for potential adverse events is a time-consuming process, typically involving manual lookup of information by physicians. This process can be expedited by CDS systems that support dynamic retrieval and filtering of adverse drug events (ADE’s), but such systems require a source of semantically-coded ADE data. We created a two-component system that addresses this need. First we created a natural language processing application which extracts adverse events from Structured Product Labels and generates a standardized ADE knowledge base. We then built a decision support service that consumes a Continuity of Care Document and returns a list of patient-specific ADE’s. Our database currently contains 534,125 ADE’s from 5602 product labels. An NLP evaluation of 9529 ADE’s showed recall of 93% and precision of 95%. On a trial set of 30 CCD’s, the system provided adverse event data for 88% of drugs and returned these results in an average of 620ms. PMID:21346964
Clinical Experience With Perampanel for Refractory Pediatric Epilepsy in One Canadian Center.
Datta, Anita N; Xu, Qi; Sachedina, Shafina; Boelman, Cyrus; Huh, Linda; Connolly, Mary B
2017-08-01
Perampanel (PER) is a new antiseizure medication that inhibits the α-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid (AMPA) class of glutamate receptors. It is important for physicians to be aware of the efficacy and tolerability of new drugs in the postmarketing phase. We performed a retrospective review of our experience with perampanel at BC Children's Hospital. Twenty-four pediatric patients prescribed perampanel from 2014 to 2016 were identified. Fifteen (63%) discontinued perampanel, and 10 (42%) had greater than 50% reduction in seizures. Twelve (50%) had behavioral and 8 (33%) had nonbehavioral adverse events. One-third experienced serious adverse events. One patient experienced oculogyric crisis, which is not previously reported with perampanel. Adverse events were not dose related and were reversible. Possible risk factors for behavioral adverse events include a history of behavioral problems with other antiseizure medications and preexisting behavioral comorbidities. It is important to counsel patients about the potential for serious adverse events, particularly behavioral, when prescribing perampanel.

Introduction Evidence of patients’ experiences is fundamental to creating effective health policy and service responses, yet is missing from our knowledge of adverse events. This protocol describes explorative research redressing this significant deficit; investigating the experiences of a large cohort of recently hospitalised patients aged 45 years and above in hospitals in New South Wales (NSW), Australia. Methods and analysis The 45 and Up Study is a cohort of 265 000 adults aged 45 years and above in NSW. Patients who were hospitalised between 1 January and 30 June 2014 will be identified from this cohort using data linkage and a random sample of 20 000 invited to participate. A cross-sectional survey (including qualitative and quantitative components) will capture patients’ experiences in hospital and specifically of adverse events. Approximately 25% of respondents are likely to report experiencing an adverse event. Quantitative components will capture the nature and type of events as well as common features of patients’ experiences. Qualitative data provide contextual knowledge of their condition and care and the impact of the event on individuals. Respondents who do not report an adverse event will report their experience in hospital and be the control group. Statistical and thematic analysis will be used to present a patient perspective of their experiences in hospital; the characteristics of patients experiencing an adverse event; experiences of information sharing after an event (open disclosure) and the other avenues of redress pursued. Interviews with key policymakers and a document analysis will be used to create a map of the current practice. Ethics and dissemination Dissemination via a one-day workshop, peer-reviewed publications and conference presentations will enable effective clinical responses and service provision and policy responses to adverse events to be developed.

The co-administration of ketamine and propofol (CoKP) is thought to maximize the beneficial profile of each medication, while minimizing the respective adverse effects of each medication. Our objective was to compare adverse events between ketamine monotherapy (KM) and CoKP for procedural sedation and analgesia (PSA) in a pediatric emergency department (ED). This was a prospective, randomized, single-blinded, controlled trial of KM vs. CoKP in patients between 3 and 21 years of age. The attending physician administered either ketamine 1 mg/kg i.v. or ketamine 0.5 mg/kg and propofol 0.5 mg/kg i.v. The physician could administer up to three additional doses of ketamine (0.5 mg/kg/dose) or ketamine/propofol (0.25 mg/kg/dose of each). Adverse events (e.g., respiratory events, cardiovascular events, unpleasant emergence reactions) were recorded. Secondary outcomes included efficacy, recovery time, and satisfaction scores. Ninety-six patients were randomized to KM and 87 patients were randomized to CoKP. There was no difference in adverse events or type of adverse event, except nausea was more common in the KM group. Efficacy of PSA was higher in the KM group (99%) compared to the CoKP group (90%). Median recovery time was the same. Satisfaction scores by providers, including nurses, were higher for KM, although parents were equally satisfied with both sedation regimens. We found no significant differences in adverse events between the KM and CoKP groups. While CoKP is a reasonable choice for pediatric PSA, our study did not demonstrate an advantage of this combination over KM. Copyright © 2017 Elsevier Inc. All rights reserved.

Depression and lower urinary tract symptoms (LUTSs) have been found to co-occur among aging men. The present study attempted to clarify the nature of this relationship, considering adverse life events as potential moderators and the inflammation as an underlying biological mechanism. The relationship between depression and LUTS was evaluated using data from the European Male Ageing Study, the largest multicenter population-based study of aging in European men. The sample included 3369 men who were assessed by means of several self-reported questionnaires, including the Beck Depression Inventory-II, the International Prostate Symptom Score, and the Adverse Life Events Scale. Participants were asked to provide information regarding general health and life-style, and medical comorbidities. Biological measures including prostate-specific antigen, testosterone, and C-reactive protein were measured. LUTS and depressive symptoms were correlated (R = 0.32, β = .10, p < .001), even after adjusting for life-style, psychological, and medical variables. A history of adverse life events was associated with both higher LUTS and Beck Depression Inventory scores. Furthermore, adverse life events moderated the LUTS-depression association (F = 22.62, b = 0.061, p < .001), which increased as a function of the number of life events. C-reactive protein was found to mediate the LUTS-depression association. This mediation effect was moderated by number of adverse life events. Participants with a history of adverse life events represent a vulnerable population in whom the association between somatic and depressive symptoms is stronger. One of the biological mechanisms underlying this association could be an activation of the central inflammatory signaling pathways.

In this paper we present a novel framework for automatic event recognition and abnormal behavior detection with attribute grammar by learning scene semantics. This framework combines learning scene semantics by trajectory analysis and constructing attribute grammar-based event representation. The scene and event information is learned automatically. Abnormal behaviors that disobey scene semantics or event grammars rules are detected. By this method, an approach to understanding video scenes is achieved. Further more, with this prior knowledge, the accuracy of abnormal event detection is increased.
Impact of adverse life events on individuals with low and high schizotypy in a nonpatient sample.

The aims of this study were to gain a better understanding of adverse life events connected with the development of schizotypal personality traits and, also, to examine whether subclinical schizotypy has a relationship with vulnerability to traumatic intrusions and avoidance. In a cross-sectional design, 198 undergraduate students completed the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE), the Impact of Event Scale (IES), and Paykel's Life Events Scale, together with other relevant scales. The number of adverse life events was significantly related to overall schizotypy measured by O-LIFE scores and positive schizotypy measured by the Unusual Experiences (UnEx) subscale. The subjective severity of life events was significantly related to Cognitive Disorganization (CogDis). Measures of positive schizotypy (UnEx and CogDis) were significantly related to the scores on the IES and on the intrusion and avoidance subscales, too. Adverse life events are associated with schizotypal personality traits, which contribute to a tendency for traumatic intrusions, even in a nonpatient sample.
Probiotics for the prevention of pediatric antibiotic-associated diarrhea.

Antibiotics are frequently prescribed in children. They alter the microbial balance within the gastrointestinal tract, commonly resulting in antibiotic-associated diarrhea (AAD). Probiotics may prevent AAD via restoration of the gut microflora. The primary objectives were to assess the efficacy and safety of probiotics (any specified strain or dose) used for the prevention of AAD in children. MEDLINE, EMBASE, CENTRAL, CINAHL, AMED, and the Web of Science (inception to November 2014) were searched along with specialized registers including the Cochrane IBD/FBD review group, CISCOM (Centralized Information Service for Complementary Medicine), NHS Evidence, the International Bibliographic Information on Dietary Supplements as well as trial registries. Letters were sent to authors of included trials, nutraceutical and pharmaceutical companies, and experts in the field requesting additional information on ongoing or unpublished trials. Conference proceedings, dissertation abstracts, and reference lists from included and relevant articles were also searched. Randomized, parallel, controlled trials in children (0 to 18 years) receiving antibiotics, that compare probiotics to placebo, active alternative prophylaxis, or no treatment and measure the incidence of diarrhea secondary to antibiotic use were considered for inclusion. Study selection, data extraction as well as methodological quality assessment using the risk of bias instrument was conducted independently and in duplicate by two authors. Dichotomous data (incidence of diarrhea, adverse events) were combined using a pooled risk ratio (RR) or risk difference (RD), and continuous data (mean duration of diarrhea, mean daily stool frequency) as mean difference (MD), along with their corresponding 95% confidence interval (95% CI). For overall pooled results on the incidence of diarrhea, sensitivity analyses included available case versus extreme-plausible analyses and random- versus fixed-effect models. To explore possible explanations for heterogeneity, a priori subgroup analysis were conducted on probiotic strain, dose, definition of antibiotic-associated diarrhea, as well as risk of bias. We also conducted post hoc subgroup analyses by patient diagnosis, single versus multi-strain, industry sponsorship, and inpatient status. The overall quality of the evidence supporting the outcomes was evaluated using the GRADE criteria. Twenty-three studies (3938 participants) met the inclusion criteria. Trials included treatment with either Bacillus spp., Bifidobacterium spp., Clostridium butyricum, Lactobacilli spp., Lactococcus spp., Leuconostoc cremoris, Saccharomyces spp., orStreptococcus spp., alone or in combination. Eleven studies used a single strain probiotic, four combined two probiotic strains, three combined three probiotic strains, one combined four probiotic strains, two combined seven probiotic strains, one included ten probiotic strains, and one study included two probiotic arms that used three and two strains respectively. The risk of bias was determined to be high or unclear in 13 studies and low in 10 studies. Available case (patients who did not complete the studies were not included in the analysis) results from 22/23 trials reporting on the incidence of diarrhea show a precise benefit from probiotics compared to active, placebo or no treatment control. The incidence of AAD in the probiotic group was 8% (163/1992) compared to 19% (364/1906) in the control group (RR 0.46, 95% CI 0.35 to 0.61; I(2) = 55%, 3898 participants). A GRADE analysis indicated that the overall quality of the evidence for this outcome was moderate. This benefit remained statistically significant in an extreme plausible (60% of children loss to follow-up in probiotic group and 20% loss to follow-up in the control group had diarrhea) sensitivity analysis, where the incidence of AAD in the probiotic group was 14% (330/2294) compared to 19% (426/2235) in the control group (RR 0.69; 95% CI 0.54 to 0.89; I(2) = 63%, 4529 participants). None of the 16 trials (n = 2455) that reported on adverse events documented any serious adverse events attributable to probiotics. Meta-analysis excluded all but an extremely small non-significant difference in adverse events between treatment and control (RD 0.00; 95% CI -0.01 to 0.01). The majority of adverse events were in placebo, standard care or no treatment group. Adverse events reported in the studies include rash, nausea, gas, flatulence, abdominal bloating, abdominal pain, vomiting, increased phlegm, chest pain, constipation, taste disturbance, and low appetite. Moderate quality evidence suggests a protective effect of probiotics in preventing AAD. Our pooled estimate suggests a precise (RR 0.46; 95% CI 0.35 to 0.61) probiotic effect with a NNT of 10. Among the various probiotics evaluated, Lactobacillus rhamnosus or Saccharomyces boulardii at 5 to 40 billion colony forming units/day may be appropriate given the modest NNT and the likelihood that adverse events are very rare. It is premature to draw conclusions about the efficacy and safety of other probiotic agents for pediatric AAD. Although no serious adverse events were observed among otherwise healthy children, serious adverse events have been observed in severely debilitated or immuno-compromised children with underlying risk factors including central venous catheter use and disorders associated with bacterial/fungal translocation. Until further research has been conducted, probiotic use should be avoided in pediatric populations at risk for adverse events. Future trials would benefit from a standard and valid outcomes to measure AAD.

Checklists are being introduced to enhance patient safety, but the results have been mixed. The goal of this research is to understand why time-outs and checklists are sometimes not effective in preventing surgical adverse events and to identify additional measures needed to reduce these events. A total of 380 consecutive patients underwent complex cardiac surgery over a 24-month period between November 2011 and November 2013 at an academic medical center, out of a total of 529 cardiac cases. Elective isolated aortic valve replacements, mitral valve repairs, and coronary artery bypass graft surgical procedures (N = 149) were excluded. A time-out was conducted in a standard fashion in all patients in accordance with the World Health Organization surgical checklist protocol. Adverse events were classified as anything that resulted in an operative delay, nonavailability of equipment, failure of drug administration, or unexpected adverse clinical outcome. These events and their details were collected every week and analyzed using a systemic causal analysis technique using a technique called CAST (causal analysis based on systems theory). This analytic technique evaluated the sociotechnical system to identify the set of causal factors involved in the adverse events and the causal factors explored to identify reasons. Recommendations were made for the improvement of checklists and the use of system design changes that could prevent such events in the future. Thirty events were identified. The causal analysis of these 30 adverse events was carried out and actionable events classified. There were important limitations in the use of standard checklists as a stand-alone patient safety measure in the operating room setting, because of multiple factors. Major categories included miscommunication between staff, medication errors, missing instrumentation, missing implants, and improper handling of equipment or instruments. An average of 3.9 recommendations were generated for each adverse event scenario. Time-outs and checklists can prevent some types of adverse events, but they need to be carefully designed. Additional interventions aimed at improving safety controls in the system design are needed to augment the use of checklists.

Association of Types of Life Events with Depressive Symptoms among Puerto Rican Youth
2016-01-01
The main objective of this study was to examine the association between four types of adverse life events (family environment, separation, social adversity, and death) and the development of depressive symptoms among Puerto Rican youth. This was a secondary analysis using three waves (2000–2004) of interview data from the Boricua Youth Study of 10–13 year old Puerto Rican youth residing in New York and Puerto Rico with no depressive symptoms at baseline (n = 977). Depressive symptoms increased with an increase in social adversity, separation, death, and death events. Youth support from parents was a significant protective factor for all adverse events and parent coping was a protective factor in social adversity events. Relying on standard diagnostic tools is ideal to identify youth meeting the criteria for a diagnosis of depression but not useful to detect youth who present with subclinical levels of depression. Youth with sub-clinical levels of depression will not get treated and are at increased risk of developing depression later in life. Adverse life events are potentially relevant to use in conjunction with other screening tools to identify Puerto Rican youth who have subclinical depression and are at risk of developing depression in later adolescence.

The economic crisis in Greece poses the necessity to resolve problems concerning both the spiralling cost and the quality assurance in the health system. The detection and the analysis of patient adverse events and medical errors are considered crucial elements of this course. The implementation of MERIS embodies a mandatory module, which adopts the trigger tool methodology for measuring adverse events and medical errors an intensive care unit [ICU] environment, and a voluntary one with web-based public reporting methodology. A pilot implementation of MERIS running in a public hospital identified 35 adverse events, with approx. 12 additional hospital days and an extra healthcare cost of €12,000 per adverse event or of about €312,000 per annum for ICU costs only. At the same time, the voluntary module unveiled 510 reports on adverse events submitted by citizens or patients. MERIS has been evaluated as a comprehensive and effective system; it succeeded in detecting the main factors that cause adverse events and discloses severe omissions of the Greek health system. MERIS may be incorporated and run efficiently nationally, adapted to the needs and peculiarities of each hospital or clinic. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

The US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS, formerly AERS) is a database that contains information on adverse event and medication error reports submitted to the FDA. Besides those from manufacturers, reports can be submitted from health care professionals and the public. The original system was started in 1969, but since the last major revision in 1997, reporting has markedly increased. Data mining algorithms have been developed for the quantitative detection of signals from such a large database, where a signal means a statistical association between a drug and an adverse event or a drug-associated adverse event, including the proportional reporting ratio (PRR), the reporting odds ratio (ROR), the information component (IC), and the empirical Bayes geometric mean (EBGM). A survey of our previous reports suggested that the ROR provided the highest number of signals, and the EBGM the lowest. Additionally, an analysis of warfarin-, aspirin- and clopidogrel-associated adverse events suggested that all EBGM-based signals were included in the PRR-based signals, and also in the IC- or ROR-based ones, and that the PRR- and IC-based signals were in the ROR-based ones. In this article, the latest information on this area is summarized for future pharmacoepidemiological studies and/or pharmacovigilance analyses. PMID:23794943
Adverse outcome pathways (AOPs) are designed to describe linkages of key events (KEs) within a biological pathway that result in an adverse outcome associated with chemical perturbation of a well-defined molecular initiating event (MIE). Risk assessors have traditionally relied ...

Europe is the largest producer of wheat, the second most widely grown cereal crop after rice. The increased occurrence and magnitude of adverse and extreme agroclimatic events are considered a major threat for wheat production. We present an analysis that accounts for a range of adverse weather events that might significantly affect wheat yield in Europe. For this purpose we analysed changes in the frequency of the occurrence of 11 adverse weather events. Using climate scenarios based on the most recent ensemble of climate models and greenhouse gases emission estimates, we assessed the probability of single and multiple adverse events occurring within one season. We showed that the occurrence of adverse conditions for 14 sites representing the main European wheat-growing areas might substantially increase by 2060 compared to the present (1981-2010). This is likely to result in more frequent crop failure across Europe. This study provides essential information for developing adaptation strategies.

Implantable cardioverter defibrillators (ICDs) used to prevent sudden cardiac arrest in children not only provide appropriate therapy in 25% of patients but also result in a significant incidence of inappropriate shocks and other device complications. ICDs placed for secondary prevention have higher rates of appropriate therapy than those placed for primary prevention. Pediatric patients with primary prevention ICDs were studied to determine time-dependent incidence of appropriate use and adverse events. A total of 140 patients aged <21 years (median age, 15 years) at first ICD implantation at Boston Children's Hospital (2000-2009) in whom devices were placed for primary prevention were retrospectively identified. Demographics and times to first appropriate shock; adverse events (including inappropriate shock, lead failure, reintervention, and complication); generator replacement and follow-up were noted. During mean follow-up of 4 years, appropriate shock occurred in 19% patients and first adverse event (excluding death/transplant) occurred in 36%. Risk of death or transplant was ≈1% per year and was not related to receiving appropriate therapy. Conditional survival analysis showed rates of appropriate therapy and adverse events decrease soon after implantation, but adverse events are more frequent than appropriate therapy throughout follow-up. Primary prevention ICDs were associated with appropriate therapy in 19% and adverse event in 36% in this cohort. The incidence of both first appropriate therapy and device-related adverse events decreased during longer periods of follow-up after implantation. This suggests that indications for continued device therapy in pediatric primary prevention ICD patients might be reconsidered after a period of nonuse. © 2014 American Heart Association, Inc.

Ultrasound (US) greatly facilitates cannulation of the internal jugular vein. Despite the ability to visualize the needle and anatomy, adverse events still occur. The authors hypothesized that the technique has limitations among certain patients and clinical scenarios. The purpose of this study was to identify characteristics of adverse events surrounding US-guided central venous cannulation (CVC). The authors assembled a prospective observational cohort of emergency department (ED) patients undergoing consecutive internal jugular CVC with US. The primary outcome of interest was a composite of acute mechanical adverse events including hematoma, arterial cannulation, pneumothorax, and unsuccessful placement. Physicians performing the CVC recorded anatomical site, reason for insertion, and acute complications. The patients with catheters were followed until the catheters were removed based on radiographic evidence or hospital nursing records. ED charts and pharmacy records contributed variables of interest. A self-reported online survey provided physician experience information. Logistic regression was used to calculate the odds of an adverse outcome. Physicians attempted 289 CVCs on 282 patients. An adverse outcome occurred in 57 attempts (19.7%, 95% confidence interval [CI] = 15.5 to 24.7), the most common being 31 unsuccessful placements (11%, 95% CI = 7.7 to 14.8). Patients with a history of end-stage renal disease (odds ratio [OR] = 3.54, 95% CI = 1.59 to 7.89), and central lines placed by operators with intermediate experience (OR = 2.26, 95% CI = 1.19 to 4.32), were most likely to encounter adverse events. Previously cited predictors such as body mass index (BMI), coagulopathy, and pulmonary hyperinflation were not significant in our final model. Acute adverse events occurred in approximately one-fifth of US-guided internal jugular central line attempts. The study identified both patient (history of end-stage renal disease) and physician (intermediate experience level) factors that are associated with acute adverse events. © 2010 by the Society for Academic Emergency Medicine.

In recent years, antipsychotic medications have increasingly been used in pediatric and geriatric populations, despite the fact that many of these drugs were approved based on clinical trials in adult patients only. Preliminary studies have shown that the "off-label" use of these drugs in pediatric and geriatric populations may result in adverse events not found in adults. In this study, we utilized the large-scale U.S. Food and Drug Administration (FDA) Adverse Events Reporting System (AERS) database to look at differences in adverse events from antipsychotics among adult, pediatric, and geriatric populations. We performed a systematic analysis of the FDA AERS database using MySQL by standardizing the database using structured terminologies and ontologies. We compared adverse event profiles of atypical versus typical antipsychotic medications among adult (18-65), pediatric (age < 18), and geriatric (> 65) populations. We found statistically significant differences between the number of adverse events in the pediatric versus adult populations with aripiprazole, clozapine, fluphenazine, haloperidol, olanzapine, quetiapine, risperidone, and thiothixene, and between the geriatric versus adult populations with aripiprazole, chlorpromazine, clozapine, fluphenazine, haloperidol, paliperidone, promazine, risperidone, thiothixene, and ziprasidone (p < 0.05, with adjustment for multiple comparisons). Furthermore, the particular types of adverse events reported also varied significantly between each population for aripiprazole, clozapine, haloperidol, olanzapine, quetiapine, risperidone, and ziprasidone (Chi-square, p < 10 -6 ). Diabetes was the most commonly reported side effect in the adult population, compared to behavioral problems in the pediatric population and neurologic symptoms in the geriatric population. We also found discrepancies between the frequencies of reports in AERS and in the literature. Our analysis of the FDA AERS database shows that there are significant differences in both the numbers and types of adverse events among these age groups and between atypical and typical antipsychotics. It is important for clinicians to be mindful of these differences when prescribing antipsychotics, especially when prescribing medications off-label.

Transforaminal epidural steroid injections (TFESI) have demonstrated efficacy and effectiveness in treatment of radicular pain. Despite little evidence of efficacy/effectiveness, interlaminar epidural steroid injections (ILESI) are advocated by some as primary therapy for radicular pain due to purported greater safety. To assess immediate and delayed adverse event rates of TFESI and ILESI injections at three academic medical centers utilizing International Spine Intervention Society practice guidelines. Quality assurance databases from a Radiology and two physical medicine and rehabilitation (PM&R) practices were interrogated. Medical records were reviewed, verifying immediate and delayed adverse events. There were no immediate major adverse events of neurologic injury or hemorrhage in 16,638 consecutive procedures in all spine segments (14,956 TFESI; 1,682 ILESI). Vasovagal reactions occurred in 1.2% of procedures, more frequently (P = 0.004) in TFESI (1.3%) than ILESI (0.5%). Dural punctures occurred in 0.06% of procedures, more commonly after ILESI (0.2% vs 0.04%, P = 0.006). Delayed follow up on PM&R patients (92.5% and 78.5, next business day) and radiology patients (63.1%, 2 weeks) identified no major adverse events of neurologic injury, hemorrhage, or infection. There were no significant differences in delayed minor adverse event rates. Central steroid response (sleeplessness, flushing, nonpositional headache) was seen in 2.6% of both TFESI and ILESI patients. 2.1% of TFESI and 1.8% of ILESI patients reported increased pain. No long-term sequelae were seen from any immediate or delayed minor adverse event. Both transforaminal and ILESI are safely performed with low immediate and delayed adverse event rates when informed by evidence-based procedural guidelines. By demonstrating comparable safety, this study suggests that the choice between ILESI and TFESIs can be based on documented efficacy and effectiveness and not driven by safety concerns.

Background Misclassification of adverse events in clinical trials can sometimes have serious consequences. Therefore, each of the many steps involved, from a patient's adverse experience to presentation in tables in publications, should be as standardised as possible, minimising the scope for interpretation. Adverse events are categorised by a predefined dictionary, e.g. MedDRA, which is updated biannually with many new categories. The objective of this paper is to study interobserver variation and other challenges of coding. Methods Systematic review using PRISMA. We searched PubMed, EMBASE and The Cochrane Library. All studies were screened for eligibility by two authors. Results Our search returned 520 unique studies of which 12 were included. Only one study investigated interobserver variation. It reported that 12% of the codes were evaluated differently by two coders. Independent physicians found that 8% of all the codes deviated from the original description. Other studies found that product summaries could be greatly affected by the choice of dictionary. With the introduction of MedDRA, it seems to have become harder to identify adverse events statistically because each code is divided in subgroups. To account for this, lumping techniques have been developed but are rarely used, and guidance on when to use them is vague. An additional challenge is that adverse events are censored if they already occurred in the run-in period of a trial. As there are more than 26 ways of determining whether an event has already occurred, this can lead to bias, particularly because data analysis is rarely performed blindly. Conclusion There is a lack of evidence that coding of adverse events is a reliable, unbiased and reproducible process. The increase in categories has made detecting adverse events harder, potentially compromising safety. It is crucial that readers of medical publications are aware of these challenges. Comprehensive interobserver studies are needed. PMID:22911755

Angiogenesis is a characteristic of renal cell carcinoma. ABT-510 is an angiogenesis inhibitor that mimics the antiangiogenic properties of thrombospondin-1. This study was designed to assess the safety and efficacy of ABT-510 in patients with advanced renal cell carcinoma. Patients with previously untreated metastatic or unresectable renal cell carcinoma were randomized to treatment with one of two doses of ABT-510, self-administered s.c. twice daily in 28-day treatment periods without intervening rest periods. End points were progression-free survival (PFS), objective response rate, overall survival, and toxicity. The objective response rate was 4% in the 10 mg twice daily group, and there were two unconfirmed PRs in the 100 mg twice daily group. Respective median PFS was 4.2 and 3.3 months, with a 6-month PFS of 39% and 32%. Median overall survival was 27.8 months (10 mg twice daily) and 26.1 months (100 mg twice daily). The most frequent adverse events were injection site reactions (84%), fatigue (50%), headache (20%), and nausea (19%). The incidence of treatment-related, grade 3/4 adverse events was low and included three bleeding episodes (gastrointestinal hemorrhage, intracranial hemorrhage, and hemoptysis) and one thrombotic event (deep vein thrombosis). No deaths were attributed to ABT-510. There was little evidence of clinical activity for ABT-510, and further evaluation as a single agent for treating advanced renal cell carcinoma is not warranted. The evidence of a favorable safety profile may justify further evaluation in combination therapy.

The study addressed the dose-response model in the association of cumulative adversity with mental health. Data of 1,725 participants aged 50+ were drawn from the Israeli component of the Survey of Health, Ageing, and Retirement in Europe. Measures included an inventory of potentially traumatic events, distress (lifetime depression, depressive symptoms), and well-being (quality of life, optimism/hope). The maximal effect of cumulative trauma emerged in the contrast between 0-2 and 3+ events, where the higher number of events related to higher distress but also to higher well-being. While self-oriented adversity revealed no, or negative, association with well-being, other-oriented adversity revealed a positive association. The study suggests an experiential dose of cumulative adversity leading to a co-activation of distress and well-being. The source of this co-activation seems to be other-oriented adversity.

To design, develop, and implement a prototype medical event-reporting system for use in transfusion medicine to improve transfusion safety by studying incidents and errors. The IDEALS concept of design was used to identify specifications for the event-reporting system, and a Delphi and subsequent nominal group technique meetings were used to reach consensus on the development of the system. An interdisciplinary panel of experts from aviation safety, nuclear power, cognitive psychology, artificial intelligence, and education and representatives of major transfusion medicine organizations participated in the development process. Setting.- Three blood centers and three hospital transfusion services implemented the reporting system. A working prototype event-reporting system was recommended and implemented. The system has seven components: detection, selection, description, classification, computation, interpretation, and local evaluation. Its unique features include no-fault reporting initiated by the individual discovering the event, who submits a report that is investigated by local quality assurance personnel and forwarded to a nonregulatory central system for computation and interpretation. An event-reporting system incorporated into present quality assurance and risk management efforts can help organizations address system structural and procedural weakness where the potential for errors can adversely affect health care outcomes. Input from the end users of the system as well as from external experts should enable this reporting system to serve as a useful model for others who may develop event-reporting systems in other medical domains.

The aim of this study was to characterize the spontaneous reports of adverse events that were received by the Central Portugal Regional Pharmacovigilance Unit. Spontaneous reports received between 01/2001 and 12/2013 were considered. The annual reporting ratios were estimated. The cases were characterized according to their seriousness, previous description, causality assessment, origin and professional group of the reporter, type of adverse event and pharmacotherapeutic groups of the suspected drugs most frequently reported. The Pharmacovigilance Unit received 2408 reports that contained 5749 adverse events. In 2013, the reporting rate was estimated at 171 reports per million inhabitants. Fifty-five percent of the reports were assessed as serious. Ninety percent of the cases were assessed as being at least possibly related with the suspected drug. The suspected drugs most frequently reported were anti-infectives for systemic use (n = 809, 33%). The most frequently reported adverse events were "Skin and subcutaneous tissue disorders" (n = 1139, 20%). There were 154 (6.4%) reports resulting in life-threatening situations and/or death, and 88 (3.6%) containing at least one adverse event assessed as serious, unknown and certain or probable. The present results are in line with those found in other studies, namely the seriousness and type of the adverse events and the pharmacotherapeutic groups of the most frequently reported suspected drugs. In the last years, the Central Portugal Regional Pharmacovigilance Unit has registered a growth in the reporting rate in general, as well as an increase in the reporting of unknown and serious adverse drug reactions.

The study was undertaken to evaluate the contribution of a process which uses clinical trial data plus linked de-identified administrative health data to forecast potential risk of adverse events associated with the use of newly released drugs by older Australian patients. The study uses publicly available data from the clinical trials of a newly released drug to ascertain which patient age groups, gender, comorbidities and co-medications were excluded in the trials. It then uses linked de-identified hospital morbidity and medications dispensing data to investigate the comorbidities and co-medications of patients who suffer from the target morbidity of the new drug and who are the likely target population for the drug. The clinical trial information and the linked morbidity and medication data are compared to assess which patient groups could potentially be at risk of an adverse event associated with use of the new drug. Applying the model in a retrospective real-world scenario identified that the majority of the sample group of Australian patients aged 65 years and over with the target morbidity of the newly released COX-2-selective NSAID rofecoxib also suffered from a major morbidity excluded in the trials of that drug, indicating a substantial potential risk of adverse events amongst those patients. This risk was borne out in post-release morbidity and mortality associated with use of that drug. Clinical trial data and linked administrative health data can together support a prospective assessment of patient groups who could be at risk of an adverse event if they are prescribed a newly released drug in the context of their age, gender, comorbidities and/or co-medications. Communication of this independent risk information to prescribers has the potential to reduce adverse events in the period after the release of the new drug, which is when the risk is greatest.Note: The terms 'adverse drug reaction' and 'adverse drug event' have come to be used interchangeably in the current literature. For consistency, the authors have chosen to use the wider term 'adverse drug event' (ADE).

There is strong evidence that post-exposure prophylaxis (PEP) with antiretroviral drugs in the timely management of occupational exposures sustained by healthcare workers decreases the risk of HIV infection and PEP is now widely used. Antiretroviral drugs have well documented toxicities and produce adverse events in patients living with HIV/AIDS. In the era of "highly active antiretroviral therapy", non-adherence to treatment has been closely linked to the occurrence of adverse events in HIV patients and this ultimately influences treatment success but the influence of adverse events on adherence during PEP is less well studied. Following the introduction of a HIV post-exposure prophylaxis program in the Korle-Bu Teaching Hospital in January 2005, the incidence of adverse events and adherence were documented in occupationally-exposed healthcare workers (HCWs) and healthcare students (HCSs). Cohort event monitoring was used in following-up on exposed HCWs/HCSs for the two study outcomes; adverse events and adherence. All adverse events reported were grouped by MedDRA system organ classification and then by preferred term according to prophylaxis regimen. Adherence was determined by the completion of prophylaxis schedule. Cox proportional regression analysis was applied to determine the factors associated with the cohort study outcomes. Differences in frequencies were tested using the Chi square test and p < 0.05 was considered statistically significant. A total of 228 exposed HCWs/HCSs were followed up during the study, made up of 101 exposed HCWs/HCSs administered lamivudine/zidovudine (3TC/AZT) for 3 days; 75 exposed HCWs/HCSs administered lamivudine/zidovudine (3TC/AZT) for 28 days; and 52 exposed HCWs/HCSs administered lamivudine/zidovudine/lopinavir-ritonavir (3TC/AZT/LPV-RTV) for 28 days. The frequency of adverse events was 28% (n = 28) in exposed HCWs/HCSs administered 3TC/AZT for 3 days, 91% (n = 68) in exposed HCWs/HCSs administered 3TC/AZT for 28 days and 96% (n = 50) in exposed HCWs/HCSs administered 3TC/AZT/LPV-RTV for 28 days. Nausea was the most commonly reported adverse events in all three regimens. Adherence was complete in all exposed HCWs/HCSs administered 3TC/AZT for 3days, 56% (n = 42) in exposed HCWs/HCSs administered 3TC/AZT for 28 days and 62% (n = 32) in exposed HCWs/HCSs administered 3TC/AZT/LPV-RTV for 28 days. In the Cox regression multi-variate analysis, exposed HCWs/HCSs administered 3TC/AZT for 3 days were 70% less likely to report adverse events compared with exposed HCWs/HCSs administered 3TC/AZT for 28 days (Adjusted HR = 0.30 [95% CI, 0.18-0.48], p < 0.001). Exposed HCWs/HCSs administered 3TC/AZT for 3 days were 75% more likely to adhere to the schedule compared with exposed HCWs/HCSs administered 3TC/AZT for 28 days (Adjusted HR = 1.75 [95% CI, 1.16-2.66], p = 0.008). The intolerance to adverse events was cited as the sole reason for truncating PEP, thereby indicating the need for adequate, appropriate and effective counselling, education, active follow-up (possibly through mobile /phone contact) and management of adverse events. Education on the need to complete PEP schedule (especially for exposed HCWs/HCSs on 28-day schedule) can lead to increased adherence, which is very critical in minimizing the risk of HIV sero-conversion. The present results also indicate that cohort event monitoring could be an effective pharmacovigilance tool in monitoring adverse events in exposed HCWs/HCSs on HIV post-exposure prophylaxis.

Self-oriented adversity refers to traumatic events that primarily inflict the self, whereas other-oriented adversity refers to events that affect the self by primarily targeting others. The present study aimed to examine whether cultural background moderates the effects of self-oriented and other-oriented adversity on mental and physical health of older adults. Using longitudinal data from the Israeli component of the Survey of Health and Retirement, we focused on 370 Jews and 239 Arabs who reported their exposure to various adversities across the lifespan, and completed questionnaires regarding mental and physical health. Results showed that the effect of self-oriented adversity on health did not differ among Jews and Arabs. However, other-oriented adversity showed a stronger effect on Arabs’ mental and physical health than on Jews’ health. Our findings suggest that the accumulation of adverse events that affect the self by primarily targeting others may have a stronger impact in collectivist cultures than in individualist cultures.

Background Calcineurin inhibitor–associated nephrotoxicity and other adverse events have prompted efforts to minimize/eliminate calcineurin inhibitor use in kidney transplant recipients. Methods This open-label, randomized, multinational study evaluated the effect of planned transition from tacrolimus to sirolimus on kidney function in renal allograft recipients. Patients received tacrolimus-based immunosuppression and then were randomized 3 to 5 months posttransplantation to transition to sirolimus or continue tacrolimus. The primary end point was percentage of patients with 5 mL/min per 1.73 m2 or greater improvement in estimated glomerular filtration rate from randomization to month 24. Results The on-therapy population included 195 patients (sirolimus, 86; tacrolimus, 109). No between-group difference was noted in percentage of patients with 5 mL/min per 1.73 m2 or greater estimated glomerular filtration rate improvement (sirolimus, 34%; tacrolimus, 42%; P = 0.239) at month 24. Sirolimus patients had higher rates of biopsy-confirmed acute rejection (8% vs 2%; P = 0.02), treatment discontinuation attributed to adverse events (21% vs 3%; P < 0.001), and lower rates of squamous cell carcinoma of the skin (0% vs 5%; P = 0.012). Conclusions Our findings suggest that renal function improvement at 24 months is similar for patients with early conversion to sirolimus after kidney transplantation versus those remaining on tacrolimus.

An imbalance in all-cause mortality was noted in tigecycline phase 3 and 4 comparative clinical trials across all studied indications. We investigated clinical failure and mortality in phase 3 and 4 complicated skin and soft-tissue infection (cSSTI) and complicated intra-abdominal infection (cIAI) tigecycline trials using descriptive analyses of a blinded adjudication of mortality and multivariate regression analyses. Attributable mortality analyses of cSSTI revealed death due to infection in 0.1% of each treatment group (P=1.000). In cIAI, there were no significant differences between tigecycline (1.2%) and comparator (0.7%) subjects who died due to infection (P=0.243). For cIAI clinical failure, treatment interaction with organ dysfunction was observed with no difference observed between clinical cure for tigecycline (85.4%) and comparator (76.7%) treatment groups (odds ratio=0.58, 95% confidence interval 0.28-1.19). Tigecycline-treated subjects had more adverse events of secondary pneumonias (2.1% vs. 1.2%) and more adverse events of secondary pneumonias with an outcome of death (0.5% vs. 0.1%). These analyses do not suggest that tigecycline is a factor either for failure (cSSTI and cIAI studies) or for death (cIAI studies). Copyright © 2015 The Authors. Published by Elsevier B.V.

Venous thromboembolism (VTE), which includes deep vein thrombosis and pulmonary embolism, is an important cause of preventable mortality and morbidity. In this study, we summarize estimates of per-patient and aggregate medical costs or expenditures attributable to incident VTE in the United States. Per-patient estimates of incremental costs can be calculated as the difference in costs between patients with and without an event after controlling for differences in underlying health status. We identified estimates of the incremental per-patient costs of acute VTEs and VTE-related complications, including recurrent VTE, post-thrombotic syndrome, chronic thromboembolic pulmonary hypertension, and anticoagulation-related adverse drug events. Based on the studies identified, treatment of an acute VTE on average appears to be associated with incremental direct medical costs of $12,000 to $15,000 (2014 US dollars) among first-year survivors, controlling for risk factors. Subsequent complications are conservatively estimated to increase cumulative costs to $18,000–23,000 per incident case. Annual incident VTE events conservatively cost the US healthcare system $7–10 billion each year for 375,000 to 425,000 newly diagnosed, medically treated incident VTE cases. Future studies should track long-term costs for cohorts of people with incident VTE, control for comorbid conditions that have been shown to be associated with VTE, and estimate incremental medical costs for people with VTE who do not survive. The costs associated with treating VTE can be used to assess the potential economic benefit and cost-savings from prevention efforts, although costs will vary among different patient groups.

Venous thromboembolism (VTE), which includes deep vein thrombosis and pulmonary embolism, is an important cause of preventable mortality and morbidity. In this study, we summarize estimates of per-patient and aggregate medical costs or expenditures attributable to incident VTE in the United States. Per-patient estimates of incremental costs can be calculated as the difference in costs between patients with and without an event after controlling for differences in underlying health status. We identified estimates of the incremental per-patient costs of acute VTEs and VTE-related complications, including recurrent VTE, post-thrombotic syndrome, chronic thromboembolic pulmonary hypertension, and anticoagulation-related adverse drug events. Based on the studies identified, treatment of an acute VTE on average appears to be associated with incremental direct medical costs of $12,000 to $15,000 (2014 US dollars) among first-year survivors, controlling for risk factors. Subsequent complications are conservatively estimated to increase cumulative costs to $18,000-23,000 per incident case. Annual incident VTE events conservatively cost the US healthcare system $7-10 billion each year for 375,000 to 425,000 newly diagnosed, medically treated incident VTE cases.

The study goals were to examine wrong intraocular lens (IOL) implant adverse events in the Veterans Health Administration (VHA), identify root causes and contributing factors, and describe system changes that have been implemented to address this challenge. This study represents collaboration between the VHA's National Center for Patient Safety (NCPS) and the National Surgery Office (NSO). This report includes 45 wrong IOL implant surgery adverse events reported to established VHA NCPS and NSO databases between July 1, 2006, and June 31, 2014. There are approximately 50,000 eye implant procedures performed each year in the VHA. Wrong IOL implant surgery adverse events are reported by VHA facilities to the NCPS and the NSO. Two authors (A.C. and J.N.) coded the reports for event type (wrong lens or expired lens) and identified the primary contributing factor (coefficient κ = 0.837). A descriptive analysis was conducted, which included the reported yearly event rate. The main outcome measure was the reported wrong IOL implant surgery adverse events. There were 45 reported wrong IOL implant surgery adverse events. Between 2011 and June 30, 2014, there was a significant downward trend (P = 0.02, R = 99.7%) at a pace of -0.08 (per 10,000 cases) every year. The most frequently coded primary contributing factor was incomplete preprocedure time-out (n = 12) followed by failure to perform double check of preprocedural calculations based upon original data and implant read-back at the time the surgical eye implant was performed (n = 10). Preventing wrong IOL implant adverse events requires diligence beyond performance of the preprocedural time-out. In 2013, the VHA has modified policy to ensure double check of preprocedural calculations and implant read-back with positive impact. Continued analysis of contributing human factors and improved surgical team communication are warranted.

Thought-action fusion (TAF) is a cognitive bias presumed to underlie the development of obsessional problems. Two domains of TAF have been identified. The first, TAF-moral, is characterized by the belief that having morally unacceptable thoughts is as bad as actually carrying them out. The second, TAF-likelihood, refers to the belief that certain thoughts cause particular events. The event can be related to one's self (likelihood-self) or to someone else (likelihood-others). The other cognitive variable of the study is attributional style. The theory of attributional styles, in terms of the causes of good and bad events, is taken into account especially in the context of depression and has four dimensions: internality-externality, stability-instability, globality-specifity, and importance-unimportance. The first objective of the present study was to investigate the relationships between TAF, and attributional style, and depressive and obsessive-compulsive symptoms. The second objective was to determine the predictors of TAF when the effects of depressive and obsessive-compulsive symptoms are statistically controlled. The sample consisted of 312 students randomly selected from different departments at Hacettepe University. The Thought-Action Fusion Scale (TAFS), Attributional Style Questionnaire (ASQ), Maudsley Obsessive-Compulsive Inventory (MOCI), and Beck Depression Inventory (BDI) were administered to these students. The correlations among all the subtypes of TAF (TAF-moral, likelihood-self, and likelihood-others), and the global attributions for bad events, BDI, and MOCI were significant. In addition, the correlation between TAF-moral and the importance of the attribution for bad events was significant. TAF-likelihood-others and TAF-likelihood-self were predicted by global attributions for bad events and TAF-moral was predicted by the importance of the attributions for bad events. TAF, and attributional styles, and depressive and obsessive-compulsive symptoms may be related to each other. The results also suggest a possible effect of other variables not controlled in this study, both on TAF and the dimensions of attributional styles.

This study was intended to determine the incidence rate of warfarin-related adverse events (e.g., bleeding) in Puerto Ricans and whether a genetic association between warfarin pharmacogenes and any of these adverse events was observed over the initiation period (i.e., the first 90 days of therapy). We conducted an observational, retrospective cohort study of pharmacogenetic association in 122 warfarin-treated, male, Puerto Rican patients (69.9 +/- 9.6 years) from the Veterans Affair Caribbean Healthcare System (VACHS) who consented to participate. Genotyping was performed using the CYP2C9 and VKORC1 assays by Luminex. Event-free survival curves were estimated using the Kaplan-Meier method and analyzed by log-rank test. Cox regression models were constructed and hazard ratios (HR) calculated. Carriers of functional CYP2C9 and VKORC1 polymorphisms demonstrated a higher incidence rate of multiple adverse events (i.e., 5.2 vs. 1.0 cases per 100 patient-months; RR = 4.8, p = 0.12) than did wild types. A significant association was observed between multiple adverse events and carrier status (HR = 2.5; 95% CI: 1.0-6.3, p = 0.04). However, no significant associations between genotypes and individual outcomes over the first 90 days of therapy were found. The association of CYP2C9 and VKORC1 genotypes and risks for adverse events due to exposure to warfarin was examined for the first time in Puerto Ricans. Despite a lack of association with individual events in this study population, our findings revealed a potential utility of genotyping for the prevention of multiple adverse events during warfarin therapy.

Safety data from countries with experience in the use of inactivated poliovirus vaccine (IPV) are important for the global polio eradication strategy to introduce IPV into the immunisation schedules of all countries. In the USA, IPV has been included in the routine immunisation schedule since 1997. We aimed to analyse adverse events after IPV administration reported to the US Vaccine Adverse Event Reporting System (VAERS). We analysed all VAERS data associated with IPV submitted between Jan 1, 2000, and Dec 31, 2012, either as individual or as combination vaccines, for all age and sex groups. We analysed the number and event type (non-serious, non-fatal serious, and death reports) of individual reports, and explored the most commonly coded event terms to describe the adverse event. We classified death reports according to previously published body-system categories (respiratory, cardiovascular, neurological, gastrointestinal, other infectious, and other non-infectious) and reviewed death reports to identify the cause of death. We classified sudden infant death syndrome as a separate cause of death considering previous concerns about sudden infant syndrome after vaccines. We used empirical Bayesian data mining methods to identify disproportionate reporting of adverse events for IPV compared with other vaccines. Additional VAERS data from 1991 to 2000 were analysed to compare the safety profiles of IPV and oral poliovirus vaccine (OPV). Of the 41,792 adverse event reports submitted, 39,568 (95%) were for children younger than 7 years. 38,381 of the reports for children in this age group (97%) were for simultaneous vaccination with IPV and other vaccines (most commonly pneumococcal and acellular pertussis vaccines), whereas standalone IPV vaccines accounted for 0·5% of all reports. 34,880 reports were for non-serious events (88%), 3905 reports were for non-fatal serious events (10%), and 783 reports were death reports (2%). Injection-site erythema was the most commonly coded term for non-serious events (29%), and pyrexia for non-fatal serious events (38%). Most deaths (96%) were in children aged 12 months or younger; most (52%) had sudden infant death syndrome as the reported cause of death. The safely profiles of combined IPV and whole-cell pertussis vaccines, OPV and whole-cell pertussis vaccines, and OPV and acellular pertussis vaccines were similar. We noted no indication of disproportionate reporting of adverse events after immunisation with IPV-containing vaccines compared with other vaccines between 1990 and 2013. Fairly few adverse events were reported for the more than 250 million IPV doses distributed between 2000 and 2012. Sudden infant death syndrome reports after IPV were consistent with reporting patterns for other vaccines. No new or unexpected vaccine safety problems were identified for fatal, non-fatal serious, and non-serious reports in this assessment of adverse events after IPV. None. Copyright © 2015 Elsevier Ltd.

Research evidence is accumulating to support an association between social adversity and the development of predisease processes and physical disease outcomes. While methodological advances have been achieved in the assessment of social adversity, significant barriers remain to their adoption in chronic disease epidemiological settings consequent upon the need to limit participant burden and restrictions imposed by cohort size and cost. A large-scale population-based cohort study, as part of the European Prospective Investigation into Cancer, Norfolk, UK, provided an opportunity to include a comprehensive postal assessment of social adversity. A total of 20,921 participants reported details of 16,031 adverse circumstances during childhood, 119,056 life events and 106,170 person-years of difficulties experienced during adulthood. Impact and adaptation indices were constructed from responses to questions regarding specific life events experienced. There was no evidence that younger participants reported more difficulties in childhood than those who were older, and no evidence of clustering of loss events involving the death of first degree relatives according to their recency. However, there was evidence of recall bias for events not involving loss with increased event rates observed in the few years immediately prior to questionnaire completion. Women reported similar events as more upsetting, and that they took longer to get over their effects, than men. Difficulties experienced in childhood, life events and difficulties in adulthood, event impact and adaptation were all associated with worse physical functional health. Reported slow adaptation to the effects of life events was associated with the largest decrement in physical functional health. These findings strengthen the rationale for including a collection of comprehensive social adversity data within chronic disease epidemiological settings and offer promise for aiding understanding of individual differences in physical disease aetiology.

Regarding the fact that rigid bronchoscopy is generally performed under general anaesthesia and this patient subgroup is remarkably morbid, encountering procedure and/or anaesthesia related complications are highly likely. Here, we aimed to assess factors influencing recovery and detect possible determinants of adverse event occurrence during these operations performed in a tertiary referral centre. Eighty-one consecutive ASA I-IV patients were recruited for this investigation. In the operating theatre after induction of anaesthesia and advancement of the device, maintenance was provided with total intravenous anaesthesia. Neuromuscular blockage was invariably administered, and patients were ventilated manually. In addition to preoperative demographic and procedural characteristics, perioperative hemodynamic variables, recovery times and observed adverse events were noted. Basic demographic properties, ASA and Mallampati scores, and procedure specific variables as lesion localization, lesion and procedure type were comparable among groups assembled with reference to event occurrence. Patients who had experienced adverse event had higher heart rates. Recovery times were comparable between Event (-) and Event (+) groups. Relationship of recovery process were individually tested with all variables and only lesion type was detected to have an effect on respiration and extubation times. Among all parameters only procedural time seemed to be associated with adverse event occurrence (mins, 22.9 ± 11.9 vs 41.6 ± 28.8, P < .001). Recovery times related with return of spontaneous respiration were significantly lower in procedures performed for treatment of tumoral diseases in this study and procedure length was determined to be the ultimate factor which had an impact on adverse event occurrence. © 2018 John Wiley & Sons Ltd.

SYNERGY, a bioabsorbable polymer-based, everolimus-eluting stent (BP-DES), recently received regulatory approval in the USA for use in percutaneous coronary interventions. Yet, information on the safety of BP-DES in routine clinical practice is limited. Our aim was to compare the safety of the recently approved BP-DES with current durable polymer drug-eluting stents (DP-DES) by analyzing adverse events, namely, stent thrombosis (ST), reported to the Manufacturer and User Facility Device Experience (MAUDE) database. The MAUDE database requires nationwide mandatory notification for adverse events on devices approved for clinical use. This database was searched for adverse events reported between 1 October 2015 and 25 December 2016, encountered after the placement of either BP-DES or DP-DES. Only those adverse events were included where the exposure period to the stents was comparable after the index procedure. Of all the adverse events reported, the event of interest was ST. A total of 951 adverse events were reported. ST occurred in 48/951 of all events, 31/309 and 17/642 when BP-DES or DP-DES were used, respectively (P=0.00001). Of the 31 ST events with BP-DES, 68% (21/31) occurred within less than or equal to 24 h of the index procedure and 52% (16/31) occurred within less than or equal to 2 h. Our results raise the possibility of an increased risk of ST, particularly early ST (within 24 h), with the recently approved BP-DES. However, because of the inherent limitations of reporting within the MAUDE database, these data merely highlight a potential need for additional surveillance and randomized trials to assess further the safety of the bioabsorbable platform.

Patients in tertiary care hospitals are more complex than in the past, but the implications of this are poorly understood as "patient complexity" has been difficult to quantify. We developed a tool, the Complexity Ruler, to quantify the amount of data (as bits) in the patient’s medical record. We designated the amount of data in the medical record as the cognitive complexity of the medical record (CCMR). We hypothesized that CCMR is a useful surrogate for true patient complexity and that higher CCMR correlates with risk of major adverse events. The Complexity Ruler was validated by comparing the measured CCMR with physician rankings of patient complexity on specific inpatient services. It was tested in a case-control model of all patients with major adverse events at a tertiary care pediatric hospital from 2005 to 2006. The main outcome measure was an externally reported major adverse event. We measured CCMR for 24 hours before the event, and we estimated lifetime CCMR. Above empirically derived cutoffs, 24-hour and lifetime CCMR were risk factors for major adverse events (odds ratios, 5.3 and 6.5, respectively). In a multivariate analysis, CCMR alone was essentially as predictive of risk as a model that started with 30-plus clinical factors. CCMR correlates with physician assessment of complexity and risk of adverse events. We hypothesize that increased CCMR increases the risk of physician cognitive overload. An automated version of the Complexity Ruler could allow identification of at-risk patients in real time.

To develop, implement and test the effect of a handoff tool for orthopaedic trauma residents that reduces adverse events associated with the omission of critical information and the transfer of erroneous information. Components of this project included a literature review, resident surveys and observations, checklist development and refinement, implementation and evaluation of impact on adverse events through a chart review of a prospective cohort compared with a historical control group. Large teaching hospital. Findings of a literature review were presented to orthopaedic residents, epidemiologists, orthopaedic surgeons and patient safety experts in face-to-face meetings, during which we developed and refined the contents of a resident handoff tool. The tool was tested in an orthopaedic trauma service and its impact on adverse events was evaluated through a chart review. The handoff tool was developed and refined during the face-to-face meetings and a pilot implementation. Adverse event data were collected on 127 patients (n = 67 baseline period; n = 60 test period). A handoff tool for use by orthopaedic residents. Adverse events in patients handed off by orthopaedic trauma residents. After controlling for age, gender and comorbidities, testing resulted in fewer events per person (25-27% reduction; P < 0.10). Preliminary evidence suggests that our resident handoff tool may contribute to a decrease in adverse events in orthopaedic patients. © The Author 2016.

Explore the unique developmental challenges and early adversity faced by youth and young adult who died of suicide. Sixty-seven suicide victims (SG) were compared with 56 living control with no suicidal ideations in the last year, matched for age, gender, and geographical region. Mixed methods were used: consensus DSM-IV diagnoses were formulated based on Structured Clinical Interview for DSM-IV (SCID)-I and -II interviews complemented by medical charts. Life calendar method was conducted with closest third party informant. Life-history calendar served to measure life events and adversity throughout the life course and were analyzed by attributing burden of adversity score per five-year segment, which was then cluster-analyzed to define suicide victim profiles. During the last year, mood disorders, abuse and dependence disorders, and anxiety disorder were between 8 and 63 times more likely to be present in the suicide group. Between 0 and 4 years old, 50% of children in the SG were exposed to abuse, physical and/or sexual violence; 60% between 5 and 9 years old; and by the time they were 10-14 years old, 77% were exposed to these forms of violence. In the control group, the respective figures were 14%, 18% and 34%. In the suicide group, the trajectories leading to suicide are different as we observe two different subgroups, one with early-onset and one with later-onset of adversity. To a large extent, people in the suicide group were exposed to major adversity and they were more likely to present cumulative comorbid disorders. Copyright © 2011 Elsevier Ltd. All rights reserved.

Background and objectives: This report summarizes the first phase 1 trial treating patients with microalbuminuric diabetic kidney disease (DKD) using FG-3019, a human monoclonal antibody to connective tissue growth factor (CTGF). CTGF is critically involved in processes of progressive fibrosis, including DKD. This phase 1, open-label, dose-escalation trial evaluated safety, pharmacokinetics, and possible therapeutic effects of FG-3019 on albuminuria, proteinuria, and tubular proteins. Design, setting, participants, and measurements: Microalbuminuric subjects (n = 24) with type 2 (79%) or type 1 (21%) diabetes received 3 or 10 mg/kg FG-3019 dosed intravenously every 14 days for four doses. Albuminuria and safety follow-up were to days 62 and 365, respectively. Results: No infusion was interrupted for symptoms, although 5 of 24 subjects had mild infusion-day adverse events thought to be possibly drug-related. No subject developed anti-FG-3019 antibodies. FG-3019 clearance was lower at 10 mg/kg than at 3 mg/kg, suggesting a saturable elimination pathway. Although this study was not designed for efficacy testing, it was notable that urinary albumin/creatinine ratio (ACR) decreased significantly from mean pretreatment ACR of 48 mg/g to mean post-treatment (day 56) ACR of 20 mg/g (P = 0.027) without evidence for a dose-response relationship. Conclusions: Treatment of microalbuminuric DKD subjects using FG-3019 was well tolerated and associated with a decrease in albuminuria. The data demonstrate a saturable pathway for drug elimination, minimal infusion adverse events, and no significant drug-attributable adverse effects over the year of follow-up. Changes in albuminuria were promising but require validation in a prospective, randomized, blinded study. PMID:20522536

Abstract While preexposure prophylaxis with oral tenofovir/emtricitabine reduces HIV acquisition rates, poor adherence to and acceptability of vaginal gels and the potential for evolving drug resistance have led to development of vaginal film formulations and other antiretroviral drugs, respectively, including the non-nucleoside reverse transcriptase inhibitor dapivirine. In this two-arm crossover study of a novel fast-dissolving dapivirine film and a previously studied semisolid dapivirine gel, 10 healthy women received a single 1.25 mg vaginal dose of each study product; one withdrew after the first dose. Clinical, pharmacokinetic, and antiviral pharmacodynamic assessments (ex vivo HIV-BaL challenge of tissue explants) were performed over 168 h postdose. Six of ten participants experienced mild to moderate adverse effects, similar between products, with no severe adverse events or adverse events attributed to study products. There were no statistically significant differences in plasma, cervicovaginal fluid (CVF), or cervical tissue dapivirine concentrations between the gel and film (all p > .05). CVF dapivirine concentrations were 1.5 and 6 log10 greater than tissue and plasma concentrations, respectively (p < .001). Both film and gel demonstrated reduced cervical tissue infectivity after ex vivo HIV challenge 5 h postdose, compared to baseline and 72-h postdose biopsies (p < .05 for gel, p = .06 for film). There was no difference in ex vivo explant HIV challenge between gel and film. The dapivirine film and gel performed similarly in terms of tolerability, pharmacokinetics, and antiviral effect. Dapivirine film may provide an alternative to pharmacokinetically comparable dapivirine gel formulations. Effectiveness remains to be tested. PMID:27809557

Hypertensive crisis is associated with poor clinical outcomes. Elevated troponin, frequently observed in hypertensive crisis, may be attributed to myocardial supply-demand mismatch or obstructive coronary artery disease (CAD). However, in patients presenting with hypertensive crisis and an elevated troponin, the prevalence of CAD and the long-term adverse cardiovascular outcomes are unknown. We sought to assess the impact of elevated troponin on cardiovascular outcomes and evaluate the role of troponin as a predictor of obstructive CAD in patients with hypertensive crisis. Patients who presented with hypertensive crisis (n = 236) were screened retrospectively. Baseline and follow-up data including the event rates were obtained using electronic patient records. Those without an assay for cardiac Troponin I (cTnI) (n = 65) were excluded. Of the remaining 171 patients, those with elevated cTnI (cTnI ≥ 0.12 ng/ml) (n = 56) were compared with those with normal cTnI (cTnI < 0.12 ng/ml) (n = 115) at 2 years for the occurrence of major adverse cardiac or cerebrovascular events (MACCE) (composite of myocardial infarction, unstable angina, hypertensive crisis, pulmonary edema, stroke or transient ischemic attack). At 2 years, MACCE occurred in 40 (71.4%) patients with elevated cTnI compared with 44 (38.3%) patients with normal cTnI [hazard ratio: 2.77; 95% confidence interval (CI): 1.79-4.27; P < 0.001]. Also, patients with elevated cTnI were significantly more likely to have underlying obstructive CAD (odds ratio: 8.97; 95% CI: 1.4-55.9; P < 0.01). In patients with hypertensive crisis, elevated cTnI confers a significantly greater risk of long-term MACCE, and is a strong predictor of obstructive CAD.

Optimum cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is essential for the curative treatment of peritoneal carcinomatosis of colorectal origin. At present, surgeons depend on visual inspection and palpation for tumour detection. Improved detection of tumour tissue using molecular fluorescence-guided surgery could not only help attain a complete cytoreduction of metastatic lesions, but might also prevent overtreatment by avoiding resection of benign lesions. For this non-randomised, single-centre feasibility study, we enrolled patients with colorectal peritoneal metastases scheduled for cytoreductive surgery and HIPEC. 2 days before surgery, 4·5 mg of the near-infrared fluorescent tracer bevacizumab-IRDye800CW was administered intravenously. The primary objectives were to determine the safety and feasibility of molecular fluorescence-guided surgery using bevacizumab-IRDye800CW. Molecular fluorescence-guided surgery was deemed safe if no allergic or anaphylactic reactions were recorded and no serious adverse events were attributed to bevacizumab-IRDye800CW. The technique was deemed feasible if bevacizumab-IRDye800CW enabled detection of fluorescence signals intraoperatively. Secondary objectives were correlation of fluorescence with histopathology by back-table imaging of the fresh surgical specimen and semi-quantitative ex-vivo analyses of formalin-fixed paraffin embedded (FFPE) tissue on all peritoneal lesions. Additionally, VEGF-α staining and fluorescence microscopy was done. This study is registered with the Netherlands Trial Registry, number NTR4632. Between July 3, 2014, and March 2, 2015, seven patients were enrolled in the study. One patient developed an abdominal sepsis 5 days postoperatively and another died from an asystole 4 days postoperatively, most probably due to a cardiovascular thromboembolic event. However, both serious adverse events were attributed to the surgical cytoreductive surgery and HIPEC procedure. No serious adverse events related to bevacizumab-IRDye800CW occurred in any of the patients. Intraoperatively, fluorescence was seen in all patients. In two patients, additional tumour tissue was detected by molecular fluorescence-guided surgery that was initially missed by the surgeons. During back-table imaging of fresh surgical specimens, a total of 80 areas were imaged, marked, and analysed. All of the 29 non-fluorescent areas were found to contain only benign tissue, whereas tumour tissue was detected in 27 of 51 fluorescent areas (53%). Ex-vivo semi-quantification of 79 FFPE peritoneal lesions showed a tumour-to-normal ratio of 6·92 (SD 2·47). Molecular fluorescence-guided surgery using the near-infrared fluorescent tracer bevacizumab-IRDye800CW is safe and feasible. This technique might be of added value for the treatment of patients with colorectal peritoneal metastases through improved patient selection and optimisation of cytoreductive surgery. A subsequent multicentre phase 2 trial is needed to make a definitive assessment of the diagnostic accuracy and the effect on clinical decision making of molecular fluorescence-guided surgery.

The prevalence of musculoskeletal injuries among nursing staff has been high due to patient handling and movement. Internationally, healthcare organizations are integrating technological equipment into patient handling and movement to improve safety. Although evidence shows that safe patient handling programs reduce work-related musculoskeletal injuries in nursing staff, it is not clear how safe these new programs are for patients. The objective of this study was to explore adverse patient events associated with safe patient handling programs and preventive approaches in US Veterans Affairs medical centers. The study surveyed a convenience sample of safe patient handling program managers from 51 US Department of Veterans Affairs medical centers to collect data on skin-related and fall-related adverse patient events. Both skin- and fall-related adverse patient events associated with safe patient handling occurred at VA Medical centers. Skin-related events included abrasions, contusions, pressure ulcers and lacerations. Fall-related events included sprains and strains, fractures, concussions and bleeding. Program managers described contextual factors in these adverse events and ways of preventing the events. The use of safe patient handling equipment can pose risks for patients. This study found that organizational factors, human factors and technology factors were associated with patient adverse events. The findings have implications for how nursing professionals can implement safe patient handling programs in ways that are safe for both staff and patients. Published by Elsevier Ltd.

BACKGROUND: Adverse health care events are injuries occurring as a result of patient care. Significant acute pain is often caused by medical and surgical procedures in children, and it has been argued that undermanaged pain should be considered to be an adverse event. Indicators are often used to identify other potential adverse events. There are currently no validated indicators for undertreated pediatric pain. OBJECTIVES: To develop a preliminary list of indicators of undermanaged pain in hospitalized pediatric patients. METHODS: The Delphi technique was used to survey experts in pediatric pain management and quality improvement. The first round used an electronic questionnaire to ask: “In your opinion, what indicators would signify that acute pain in a child has not been adequately controlled?” Responses were grouped together in semantically similar themes, providing a list of possible adverse event indicators. Using this list, an electronic questionnaire was developed for round 2 asking respondents to indicate the importance of each potential indicator. RESULTS: All but one indicator achieved a level of consensus ≥70%. Separate indicators emerged for postoperative and procedural pain. An additional distinction was made between indicators that could be identified by chart review and those requiring observation of practice and assessment from the child or parent. DISCUSSION: The adverse care indicators developed in the present study require further refinement. There is a need to test their clinical usability and to determine whether these indicators actually identify undermanaged pain in clinical practice. The present study is an important first step in identifying undermanaged pain in hospital and treating it as an adverse event. CONCLUSION: The adverse care indicators developed in the present study are the first step in conceptualizing mismanaged pain as an adverse event. PMID:24093121

As part of a larger investigation of the adverse effects of mental disorders on role functioning, we examined the associations of early-onset mental disorders with subsequent educational attainment in a large nationally representative survey of the US adult population. Diagnoses and age of onset for each of 17 DSM-IV disorders were assessed through retrospective self-report with the fully structured WHO Composite International Diagnostic Instrument (CIDI). Survival analysis was used to examine the associations between early-onset DSM-IV/CIDI disorders and subsequent termination of schooling with controls for socio-demographic characteristics and childhood adversities (i.e. childhood traumatic events, childhood neglect, parental mental illness, family disruption, and low parental educational attainment). Mental disorders were found to be significantly associated with termination of schooling prior to completion of each of four educational milestones (primary school graduation, high school graduation, college entry, college graduation), with odds ratios in the range of 1.3-7.0. The proportion of school terminations attributable to mental disorders was largest for high school graduation (10.2%) but also meaningful for primary school graduation (3.8%), college entry (4.4%) and college graduation (2.6%). These results add to a growing body of evidence documenting a wide variety of adverse life course effects of mental disorders.

We characterized associations between central nervous system (CNS) adverse events and brain neurotransmitter transporter/receptor genomics among participants randomized to efavirenz-containing regimens in AIDS Clinical Trials Group studies in the USA. Four clinical trials randomly assigned treatment-naive participants to efavirenz-containing regimens. Genome-wide genotype and PrediXcan were used to infer gene expression levels in tissues including 10 brain regions. Multivariable regression models stratified by race/ethnicity were adjusted for CYP2B6/CYP2A6 genotypes that predict plasma efavirenz exposure, age, and sex. Combined analyses also adjusted for genetic ancestry. Analyses included 167 cases with grade 2 or greater efavirenz-consistent CNS adverse events within 48 weeks of study entry, and 653 efavirenz-tolerant controls. CYP2B6/CYP2A6 genotype level was independently associated with CNS adverse events (odds ratio: 1.07; P=0.044). Predicted expression of six genes postulated to mediate efavirenz CNS side effects (SLC6A2, SLC6A3, PGR, HTR2A, HTR2B, HTR6) were not associated with CNS adverse events after correcting for multiple testing, the lowest P value being for PGR in hippocampus (P=0.012), nor were polymorphisms in these genes or AR and HTR2C, the lowest P value being for rs12393326 in HTR2C (P=6.7×10). As a positive control, baseline plasma bilirubin concentration was associated with predicted liver UGT1A1 expression level (P=1.9×10). Efavirenz-related CNS adverse events were not associated with predicted neurotransmitter transporter/receptor gene expression levels in brain or with polymorphisms in these genes. Variable susceptibility to efavirenz-related CNS adverse events may not be explained by brain neurotransmitter transporter/receptor genomics.

Ways of increasing the production of wheat, the most widely grown cereal crop, will need to be found to meet the increasing demand caused by human population growth in the coming decades. This increase must occur despite the decrease in yield gains now being reported in some regions, increased price volatility and the expected increase in the frequency of adverse weather events that can reduce yields. However, if and how the frequency of adverse weather events will change over Europe, the most important wheat-growing area, has not yet been analysed. Here, we show that the accumulated probability of 11 adverse weather events with the potential to significantly reduce yield will increase markedly across all of Europe. We found that by the end of the century, the exposure of the key European wheat-growing areas, where most wheat production is currently concentrated, may increase more than twofold. However, if we consider the entire arable land area of Europe, a greater than threefold increase in risk was predicted. Therefore, shifting wheat production to new producing regions to reduce the risk might not be possible as the risk of adverse events beyond the key wheat-growing areas increases even more. Furthermore, we found a marked increase in wheat exposure to high temperatures, severe droughts and field inaccessibility compared with other types of adverse events. Our results also showed the limitations of some of the presently debated adaptation options and demonstrated the need for development of region-specific strategies. Other regions of the world could be affected by adverse weather events in the future in a way different from that considered here for Europe. This observation emphasizes the importance of conducting similar analyses for other major wheat regions. © 2015 The Authors.

Purpose: To investigate adverse events after samarium Sm 153 lexidronam and the effect of pre- and post-samarium Sm 153 lexidronam external beam radiation therapy (EBRT) and/or chemotherapy on myelosuppression in patients who received samarium Sm 153 lexidronam for osseous metastases. Methods and Materials: We performed a single-institution retrospective review of 139 patients treated with samarium Sm 153 lexidronam between November 1997 and February 2008. New-onset adverse events after samarium Sm 153 lexidronam were reported. The effect of samarium Sm 153 lexidronam on platelet and peripheral white blood cell counts and the duration of myelosuppression after samarium Sm 153 lexidronam plusmore » EBRT and/or chemotherapy were calculated. Differences in the prevalence of adverse events among patients with varying treatment histories were evaluated with the Pearson chi-square test. Results: Hematologic follow-up was available for 103 patients. Chemotherapy and/or EBRT had no effect on the magnitude or duration of myelosuppression. The most common nonhematologic adverse events were acute lower extremity edema (n = 27) and acute and transient neuropathy (n = 29). Patients treated with chemotherapy after samarium Sm 153 lexidronam had a higher prevalence of lower extremity edema (9 of 18 [50%]) than those who were not treated with chemotherapy after samarium Sm 153 lexidronam (18 of 85 [21.2%]) (p = 0.01, chi-square test). No adverse events were correlated with EBRT. Conclusions: Our observation of new-onset, acute and transient edema and neuropathy after samarium Sm 153 lexidronam and of a relationship between edema and post-samarium Sm 153 lexidronam chemotherapy suggests the need for re-examination of patients in past series or for a prospective investigation with nonhematologic adverse events as a primary endpoint.« less
The cost of nurse-sensitive adverse events.
Pappas, Sharon Holcombe
2008-05-01
The aim of this study was to describe the methodology for nursing leaders to determine the cost of adverse events and effective levels of nurse staffing. The growing transparency of quality and cost outcomes motivates healthcare leaders to optimize the effectiveness of nurse staffing. Most hospitals have robust cost accounting systems that provide actual patient-level direct costs. These systems allow an analysis of the cost consumed by patients during a hospital stay. By knowing the cost of complications, leaders have the ability to justify the cost of improved staffing when quality evidence shows that higher nurse staffing improves quality. An analysis was performed on financial and clinical data from hospital databases of 3,200 inpatients. The purpose was to establish a methodology to determine actual cost per case. Three diagnosis-related groups were the focus of the analysis. Five adverse events were analyzed along with the costs. A regression analysis reported that the actual direct cost of an adverse event was dollars 1,029 per case in the congestive heart failure cases and dollars 903 in the surgical cases. There was a significant increase in the cost per case in medical patients with urinary tract infection and pressure ulcers and in surgical patients with urinary tract infection and pneumonia. The odds of pneumonia occurring in surgical patients decreased with additional registered nurse hours per patient day. Hospital cost accounting systems are useful in determining the cost of adverse events and can aid in decision making about nurse staffing. Adverse events add costs to patient care and should be measured at the unit level to adjust staffing to reduce adverse events and avoid costs.

The objective of this systematic review was to summarise the current evidence on the diagnostic accuracy of the HEART score for predicting major adverse cardiac events in patients presenting with undifferentiated chest pain to the emergency department. Two investigators independently searched Medline, Embase and Cochrane databases between 2008 and May 2016 identifying eligible studies providing diagnostic accuracy data on the HEART score for predicting major adverse cardiac events as the primary outcome. For the 12 studies meeting inclusion criteria, study characteristics and diagnostic accuracy measures were systematically extracted and study quality assessed using the QUADAS-2 tool. After quality assessment, nine studies including data from 11,217 patients were combined in the meta-analysis applying a generalised linear mixed model approach with random effects assumption (Stata 13.1). In total, 15.4% of patients (range 7.3-29.1%) developed major adverse cardiac events after a mean of 6 weeks' follow-up. Among patients categorised as 'low risk' and suitable for early discharge (HEART score 0-3), the pooled incidence of 'missed' major adverse cardiac events was 1.6%. The pooled sensitivity and specificity of the HEART score for predicting major adverse cardiac events were 96.7% (95% confidence interval (CI) 94.0-98.2%) and 47.0% (95% CI 41.0-53.5%), respectively. Patients with a HEART score of 0-3 are at low risk of incident major adverse cardiac events. As 3.3% of patients with major adverse cardiac events are 'missed' by the HEART score, clinicians must ask whether this risk is acceptably low for clinical implementation.

Association rule mining in the US Vaccine Adverse Event Reporting System (VAERS).
Wei, Lai; Scott, John
2015-09-01
Spontaneous adverse event reporting systems are critical tools for monitoring the safety of licensed medical products. Commonly used signal detection algorithms identify disproportionate product-adverse event pairs and may not be sensitive to more complex potential signals. We sought to develop a computationally tractable multivariate data-mining approach to identify product-multiple adverse event associations. We describe an application of stepwise association rule mining (Step-ARM) to detect potential vaccine-symptom group associations in the US Vaccine Adverse Event Reporting System. Step-ARM identifies strong associations between one vaccine and one or more adverse events. To reduce the number of redundant association rules found by Step-ARM, we also propose a clustering method for the post-processing of association rules. In sample applications to a trivalent intradermal inactivated influenza virus vaccine and to measles, mumps, rubella, and varicella (MMRV) vaccine and in simulation studies, we find that Step-ARM can detect a variety of medically coherent potential vaccine-symptom group signals efficiently. In the MMRV example, Step-ARM appears to outperform univariate methods in detecting a known safety signal. Our approach is sensitive to potentially complex signals, which may be particularly important when monitoring novel medical countermeasure products such as pandemic influenza vaccines. The post-processing clustering algorithm improves the applicability of the approach as a screening method to identify patterns that may merit further investigation.

Introduction Fluoride varnish is an effective prevention intervention for caries in young children. Its routine use in clinical care is supported by meta-analyses and recommended by clinical guidelines, including the US Preventive Services Task Force (B rating). This report is the first prospective systematic assessment of adverse events related to fluoride varnish treatment in young children. Methods We determined the incidence of adverse events related to fluoride varnish treatment in 3 clinical trials on the prevention of early childhood caries, conducted under the auspices of the Early Childhood Caries Collaborating Centers, an initiative sponsored by the National Institute of Dental and Craniofacial Research. Each trial incorporated use of fluoride varnish in its protocol and systematically queried all children’s parents or legal guardians about the occurrence of acute adverse events after each fluoride varnish treatment. Results A total of 2,424 community-dwelling, dentate children aged 0 to 5 years were enrolled and followed for up to 3 years. These children received a cumulative total of 10,249 fluoride varnish treatments. On average, each child received 4.2 fluoride varnish treatments. We found zero fluoride varnish–related adverse events. Conclusion Fluoride varnish was not associated with treatment-related adverse events in young children. Our findings support its safety as an effective prevention intervention for caries in young children. PMID:28207379

To describe the effect of implementing the Joint Commission on Accreditation of Healthcare Organization's guidelines for procedural sedation and analgesia (PSA) on the frequency of adverse events occurring during sedation. Prospective, descriptive study. Urban, tertiary care children's hospital. Patients requiring PSA. A PSA committee and a standardized protocol for PSA were developed during a 6-month period. Institutional oversight was initiated to monitor practitioner compliance with the program. Data were abstracted from the sedation record. The change in incidence of adverse events during PSA during the study. The strength of the association was determined by computing the Pearson product moment correlation. A total of 14 386 patients received PSA between July 1, 2001, and June 30, 2004. During the study, 7.6% of patients had an adverse event, with the most common being hypoxemia (39.7% of all adverse events). A trend toward a decrease in the incidence of adverse events was found during the study (Pearson product moment correlation, -0.68; P<.001). Implementation of the 2001 Joint Commission on Accreditation of Healthcare Organizations guidelines for the provision of PSA appeared to lead to a decrease in the incidence of adverse events during the study. Implementation of uniform standards of monitoring and care for the provision of PSA may lead to safer conditions for pediatric patients undergoing PSA.

Background Adverse consequences of medical interventions are a source of concern, but clinical trials may lack power to detect elevated rates of such events, while observational studies have inherent limitations. Meta-analysis allows the combination of individual studies, which can increase power and provide stronger evidence relating to adverse events. However, meta-analysis of adverse events has associated methodological challenges. The aim of this study was to systematically identify and review the methodology used in meta-analyses where a primary outcome is an adverse or unintended event, following a therapeutic intervention. Methods Using a collection of reviews identified previously, 166 references including a meta-analysis were selected for review. At least one of the primary outcomes in each review was an adverse or unintended event. The nature of the intervention, source of funding, number of individual meta-analyses performed, number of primary studies included in the review, and use of meta-analytic methods were all recorded. Specific areas of interest relating to the methods used included the choice of outcome metric, methods of dealing with sparse events, heterogeneity, publication bias and use of individual patient data. Results The 166 included reviews were published between 1994 and 2006. Interventions included drugs and surgery among other interventions. Many of the references being reviewed included multiple meta-analyses with 44.6% (74/166) including more than ten. Randomised trials only were included in 42.2% of meta-analyses (70/166), observational studies only in 33.7% (56/166) and a mix of observational studies and trials in 15.7% (26/166). Sparse data, in the form of zero events in one or both arms where the outcome was a count of events, was found in 64 reviews of two-arm studies, of which 41 (64.1%) had zero events in both arms. Conclusions Meta-analyses of adverse events data are common and useful in terms of increasing the power to detect an association with an intervention, especially when the events are infrequent. However, with regard to existing meta-analyses, a wide variety of different methods have been employed, often with no evident rationale for using a particular approach. More specifically, the approach to dealing with zero events varies, and guidelines on this issue would be desirable. PMID:22553987

Individuals who suffered traumatic events or adverse experiences during their childhood have an increased risk of developing during adulthood physical problems, aggressive behavior, and psychiatric disorders, such as schizophrenia. Patients diagnosed with schizophrenia have higher rates of traumatic experiences during childhood than the general population, and those who suffered multiple traumatic events have an increased risk of disease relapse. The current study aims to determine the prevalence of different types of adverse experiences during childhood among a male patient sample with schizophrenia. An Observational descriptive cross-sectional study was conducted at Jose T. Borda Hospital, in Buenos Aires, Argentina. Participants included 51 male patients between the ages of 18 and 63 years with a diagnosis of schizophrenia. Semi-structured interviews were conducted, applying a socio-demographic questionnaire, SCID I and II scales to assess psychiatric diagnosis, and the Adverse Childhood Experiences (ACE) Questionnaire to evaluate the presence of adverse childhood experiences. Statistical analyses were conducted using SPSS 22 software. We observed that 94% of participants had experienced at least one adverse childhood experience. Most (63%) suffered from 4 or more disruptive child events. A high prevalence of family history of mental illness was found, also emotional abuse and neglect. Most traumatic events occurred within the family group. It was found a moderately significant relationship between patients who suffered adverse events and the presence of auditory hallucinations.
Exploring unplanned ICU admissions: a systematic review.

Adverse events are unintended patient injuries or complications that arise from healthcare management resulting in death, disability or prolonged hospital stay. Adverse events that require critical care are a considerable financial burden to the healthcare system. Medical record review seems to be a reliable method for detecting adverse events. To synthesize the best available evidence regarding the estimates of the incidence and preventability of adverse events that necessitate intensive care admission; to determine the type and consequences (patient harm, mortality, length of ICU stay and direct medical costs) of these adverse events. MEDLINE (from 1966 to present), EMBASE (from 1974 to present) and CENTRAL (version 1-2010) were searched for studies reporting on unplanned admissions to intensive care units (ICUs). Databases of reports, conference proceedings, grey literature, ongoing research, relevant patient safety organizations and two journals were searched for additional studies. Reference lists of retrieved papers were searched and authors were contacted in an attempt to find any further published or unpublished work. Only quantitative studies that used chart review for the detection of adverse events requiring intensive care admission were considered for eligibility. Studies that were published in the English, Dutch, German, French or Spanish language were included. Two reviewers independently extracted data and assessed the methodological quality of the included studies. 28 studies in the English language and one study in French were included. Of these, two were considered duplicate publications and therefore 27 studies were reviewed. Meta-analysis of the data was not appropriate due to statistical heterogeneity between studies; therefore, results are presented in a descriptive way. Studies were categorized according to the population and the providers of care. 1) The majority of the included studies investigated unplanned intensive care admissions after anesthetic procedures (UIA). 2) Only a few studies examined patients on general wards being at risk for clinical deterioration. The overall incidence of surgical and medical adverse events compared with ICU admissions ranged from 1.1% to 37.2%. 3) The third category of studies examined patients that were readmitted on ICUs. ICU readmission rates varied from 0% to 18.3%. Nine studies explicitly reported on the preventability of adverse outcomes. The preventability rates of the adverse events varied from 17% to 76.5%. Preventable adverse events are further synthesized by type of event and patterns of preventability are being formulated. Consequences of the adverse events included a mean length of ICU stay that ranged from 1.5 days to 10.4 days for the patient's first stay in ICU. Mortality rates varied between 0% and 58%. Adverse events are a persistent and an important reason for admission to the ICU. However, there is relatively weak evidence to estimate an overall incidence and preventability rate of these events. In addition, estimates on preventability are prone to subjective judgments. Variability in methodology and definitions, and poor reporting in studies may be the main reasons for study heterogeneity. Unplanned intensive care admission within 24 hours of a procedure with an anesthetist in attendance (UIA) is a recommended clinical indicator in surgical patients. Several authors recommend early detection of patients with clinical instability on general wards and the implementation of rapid response teams. Step-down or intermediate care units could be a useful strategy for patients that require monitoring to avoid ICU readmissions. There is a need for further studies on the detection of adverse events. The poor quality of current research evidence and the heterogeneity across studies requires that planning of future studies should aim to standardize measures of outcomes to allow for comparisons across studies. This area of research is important in order to identify and explain failure of healthcare systems leading to patient harm, with the ultimate aim to improve the quality and safety of care.

OTC combination cold remedies are widely used in Japan. In the present study, we aimed to evaluate the adverse event profiles of OTC combination cold remedy based on the components using the Japanese Adverse Drug Event Report (JADER) database. The JADER database contained 430587 reports between April 2004 and November 2016. 1084 adverse events associated with the use of OTC combination cold remedy were reported. Reporting odds ratio (ROR) was used to detect safety signals. The ROR values for "skin and subcutaneous tissue disorders", "hepatobiliary disorders", and "immune system disorders" stratified by system organ class of the Medical Dictionary for Regulatory Activities (MedDRA) were 9.82 (8.71-11.06), 2.63 (2.25-3.07), and 3.13 (2.63-3.74), respectively. OTC combination cold remedy containing acetaminophen exhibited a significantly higher reporting ratio for "hepatobiliary disorders" than OTC combination cold remedy without acetaminophen. We demonstrated the potential risk of OTC combination cold remedy in a real-life setting. Our results suggested that the monitoring of individuals using OTC combination cold remedy is important.

Most influenza vaccines are generally safe, but influenza vaccines can cause rare serious adverse events. Some adverse events, such as fever and febrile seizures, are more common in children than adults. There can be differences in the safety of vaccines in different populations due to underlying differences in genetic predisposition to the adverse event. Live attenuated vaccines have not been studied adequately in children under 2 years of age to determine the risks of adverse events; more studies are needed to address this and several other priority safety issues with all influenza vaccines in children. All vaccines intended for use in children require safety testing in the target age group, especially in young children. Safety of one influenza vaccine in children should not be extrapolated to assumed safety of all influenza vaccines in children. The low rates of adverse events from influenza vaccines should not be a deterrent to the use of influenza vaccines because of the overwhelming evidence of the burden of disease due to influenza in children.

Patients' perceptions and experiences of medication efficacy, medication adverse events, dosing frequency, and dosing complexity have been found to influence adherence to injectable disease-modifying treatments (DMTs) in patients with multiple sclerosis (MS). The aim of this study was to quantify patient preferences for features of injectable DMTs for MS. Adult patients in the United States (US) with a self-reported diagnosis of MS completed an online discrete-choice experiment survey to assess preference for a number of features of a hypothetical injectable DMT. Patients chose hypothetical treatments in paired comparisons, where each treatment was described by features or attributes, including the number of years until disability progression, the number of relapses in the next 4 years, injection time, the frequency of injections, the occurrence of flu-like symptoms (FLS), and severity of injection-site reactions. Random-parameters logit regression parameters were used to calculate preference weights of attribute levels and the relative importance of changes in treatment features. Of the 205 patients who completed the survey, 192 provided sufficient data for analysis. The results indicated a broad range of tradeoffs that patients would be willing to make. With regard to this, the relative importance of an improvement in the number of years until disability progression from 1 to 2 (i.e., vertical distance between preference weights for these attribute levels) was 0.9 [95% confidence interval (CI) 0.5-1.2], the relative importance of this change was approximately equivalent to that of an improvement from 12 injections per month to two (mean 0.8, 95% CI 0.4-1.2), or approximately equivalent to a decrease from four to one relapses in the next 4 years (mean 0.8, 95% CI 0.5-1.2), or FLS 3 days after every injection to 3 days after some injections (mean 1.0, 95% CI 0.6-1.4). These results suggest that an improvement in treatment efficacy may be as important as a reduction in injection frequency or a reduction in some adverse events for patients who self-administer injectable DMTs for MS. Understanding the preferences of patients who use injectable treatments will inform the development of such treatments, which may in turn improve patient medication adherence and well-being.

Structured Product Labels follow an XML-based document markup standard approved by the Health Level Seven organization and adopted by the US Food and Drug Administration as a mechanism for exchanging medical products information. Their current organization makes their secondary use rather challenging. We used the Side Effect Resource database and DailyMed to generate a comparison dataset of 1159 Structured Product Labels. We processed the Adverse Reaction section of these Structured Product Labels with the Event-based Text-mining of Health Electronic Records system and evaluated its ability to extract and encode Adverse Event terms to Medical Dictionary for Regulatory Activities Preferred Terms. A small sample of 100 labels was then selected for further analysis. Of the 100 labels, Event-based Text-mining of Health Electronic Records achieved a precision and recall of 81 percent and 92 percent, respectively. This study demonstrated Event-based Text-mining of Health Electronic Record's ability to extract and encode Adverse Event terms from Structured Product Labels which may potentially support multiple pharmacoepidemiological tasks.

The present study examined the relationship between childhood socioeconomic status (SES), childhood maltreatment, and the volumes of the hippocampus and amygdala between the ages of 25 and 36 years. Previous work has linked both low SES and maltreatment with reduced hippocampal volume in childhood, an effect attributed to childhood stress. In 46 adult subjects, only childhood maltreatment, and not childhood SES, predicted hippocampal volume in regression analyses, with greater maltreatment associated with lower volume. Neither factor was related to amygdala volume. When current SES and recent interpersonal stressful events were also considered, recent interpersonal stressful events predicted smaller hippocampal volumes over and above childhood maltreatment. Finally, exploratory analyses revealed a significant sex by childhood SES interaction, with women’s childhood SES showing a significantly more positive relation (less negative) with hippocampus volume than men’s. The overall effect of childhood maltreatment but not SES, and the sex-specific effect of childhood SES, indicate that different forms of stressful childhood adversity affect brain development differently.

[Is regression of atherosclerotic plaque possible?
Páramo, José A; Civeira, Fernando
As it is well-known, a thrombus evolving into a disrupted/eroded atherosclerotic plaque causes most acute coronary syndromes. Plaque stabilization via reduction of the lipid core and/or thickening of the fibrous cap is one of the possible mechanisms accounted for the clinical benefits displayed by different anti-atherosclerotic strategies. The concept of plaque stabilization was developed to explain how lipid-lowering agents could decrease adverse coronary events without substantial modifications of the atherosclerotic lesion ('angiographic paradox'). A number of imaging modalities (vascular ultrasound and virtual histology, MRI, optical coherence tomography, positron tomography, etc.) are used for non-invasive assessment of atherosclerosis; most of them can identify plaque volume and composition beyond lumen stenosis. An 'aggressive' lipid-lowering strategy is able to reduce the plaque burden and the incidence of cardiovascular events; this may be attributable, at least in part, to plaque-stabilizing effects.

In an adverse outcome pathway (AOP), the target site dose participates in a molecular initiating event (MIE), which in turn triggers a sequence of key events leading to an adverse outcome (AO). Quantitative AOPs (QAOP) are needed if AOP characterization is to address risk as well...
Adversomics: a new paradigm for vaccine safety and design

Summary Despite the enormous population benefits of routine vaccination, vaccine adverse events and reactions, whether real or perceived, have posed one of the greatest barriers to vaccine acceptance—and thus to infectious disease prevention—worldwide. A truly integrated clinical, translational, and basic science approach is required to understand the mechanisms behind vaccine adverse events, predict them, and then apply this knowledge to new vaccine design approaches that decrease, or avoid, these events. The term “adversomics” was first introduced in 2009 and refers to the study of vaccine adverse reactions using immunogenomics and systems biology approaches. In this review, we present the current state of adversomics research, review known associations and mechanisms of vaccine adverse events/reactions, and outline a plan for the further development of this emerging research field.

With the rising consumption of so-called energy drinks over the last few years, there has been a growing body of literature describing significant adverse health events after the ingestion of these beverages. To gain further insight about the clinical spectrum of these adverse events, we conducted a literature review. Using PubMed and Google-Scholar, we searched the literature from January 1980 through May 2014 for articles on the adverse health effects of energy drinks. A total of 2097 publications were found. We then excluded molecular and industry-related studies, popular media reports, and case reports of isolated caffeine toxicity, yielding 43 reports. Energy drink consumption is a health issue primarily of the adolescent and young adult male population. It is linked to increased substance abuse and risk-taking behaviors. The most common adverse events affect the cardiovascular and neurological systems. The most common ingredient in energy drinks is caffeine, and it is believed that the adverse events are related to its effects, as well as potentiating effects of other stimulants in these drinks. Education, regulation, and further studies are required.

Antibiotic prophylaxis in dogs undergoing surgical procedures frequently involves the administration of a product without a veterinary licence. Two drugs commonly used for this purpose are the clavulanate amoxicillin Augmentin and the cefuroxime Zinacef. This prospective observational study aims to compare the incidence of adverse events associated with these two antibiotics in a clinical setting. The authors hypothesised that a higher incidence of adverse effects would be observed with Augmentin. Sixty-five dogs were included in the study and adverse events were recorded using a modified scoring system. A significantly higher incidence of adverse events to Augmentin (8/22; 36 per cent) was observed compared with Zinacef (1/43; 2 per cent) (P=0.0003). The majority of these adverse events involved cutaneous signs and/or hypotension. These findings might be taken into consideration when selecting one of these intravenous antibiotics for prophylaxis in anaesthetised dogs undergoing surgery. © British Veterinary Association (unless otherwise stated in the text of the article) 2017.

Purpose We aimed to examine the risk factors, time of onset, incidence rates, and outcomes of thromboembolic events induced by bevacizumab in patients with cancer using the Japanese Adverse Drug Event Report (JADER) database of the Pharmaceuticals and Medical Devices Agency. Methods Adverse event data recorded in the JADER database between January 2004 and January 2015 were used. After screening the data using the generic drug name bevacizumab, patient data were classified into two groups by age and five groups by cancer type. The histories of disorders were also categorized. Arterial thromboembolic event and venous thromboembolic event were classified as "favorable" or "unfavorable" outcomes. Results In total, 6076 patients were reported to have developed adverse events during the sample period, of which 233 and 453 developed arterial thromboembolic event and venous thromboembolic event, respectively. Logistic analysis suggested that the presence of cancer was a significant risk factor for both arterial thromboembolic event and venous thromboembolic event. Age (≥70 years), histories of either hypertension or diabetes mellitus were also risk factors for arterial thromboembolic event. Median cumulative times of onset for arterial thromboembolic event and venous thromboembolic event were 60 and 80 days, respectively, and were not significantly different by the log-rank test. By the chi-square test, the rate of unfavorable outcomes was found to be higher after developing arterial thromboembolic event than after venous thromboembolic event. Conclusion Thromboembolism is a leading cause of mortality in patients with cancer. Patients should be monitored for the symptoms of thromboembolic events right from the initial stages of bevacizumab treatment.

Postsedation neuroexcitation is sometimes attributed to intravenous injection of the sedative-hypnotic drug propofol. The movements associated with these events have strongly suggested convulsive activity, but they rarely have been comprehensively evaluated. We present video recordings of 3 healthy young patients who underwent elective surgery under conscious sedation and emerged from sedation with transient but repetitive violent motor activity and impaired consciousness. These manifestations required considerable mobilization of multiple health care workers to protect the patient from inflicting harm. All patients received propofol, and all fully recovered without adverse sequelae. We postulate that these movements are propofol related. Importantly, we found no evidence of seizures clinically or electrographically. Copyright © 2017 Mayo Foundation for Medical Education and Research. Published by Elsevier Inc. All rights reserved.

Over 20 years have passed since the introduction of the tri-iodinated low-osmolar nonionic contrast agents such as iopamidol, iohexol, ioversol and iopromide. During this time, most cardiology practices have switched to these nonionic agents to avoid the nuisance side effects and cardiac adverse events associated with the older ionic contrast agents. Although the improved tolerability of the nonionic agents is generally attributed to their decreased osmolality (approximately half that of the older ionic contrast agents), in fact, these contrast agents also differ from the older agents in their ionicity, viscosity and direct chemotoxicity. The impact of these properties on safety, together with cost differences, should be considered when selecting a contrast agent.
