Project description:ObjectiveDetecting adverse events is pivotal for measuring and improving medical safety, yet current techniques discourage routine screening. The authors hypothesized that discharge summaries would include information on adverse events, and they developed and evaluated an electronic method for screening medical discharge summaries for adverse events.DesignA cohort study including 424 randomly selected admissions to the medical services of an academic medical center was conducted between January and July 2000. The authors developed a computerized screening tool that searched free-text discharge summaries for trigger words representing possible adverse events.MeasurementsAll discharge summaries with a trigger word present underwent chart review by two independent physician reviewers. The presence of adverse events was assessed using structured implicit judgment. A random sample of discharge summaries without trigger words also was reviewed.ResultsFifty-nine percent (251 of 424) of the discharge summaries contained trigger words. Based on discharge summary review, 44.8% (327 of 730) of the alerted trigger words indicated a possible adverse event. After medical record review, the tool detected 131 adverse events. The sensitivity and specificity of the screening tool were 69% and 48%, respectively. The positive predictive value of the tool was 52%.ConclusionMedical discharge summaries contain information regarding adverse events. Electronic screening of discharge summaries for adverse events using keyword searches is feasible but thus far has poor specificity. Nonetheless, computerized clinical narrative screening methods could potentially offer researchers and quality managers a means to routinely detect adverse events.

Project description:IntroductionMedical Emergency Teams (METs), also known as Rapid Response Teams, are recommended as a patient safety measure. A potential benefit of implementing an MET is the capacity to systematically assess preventable adverse events, which are defined as poor outcomes caused by errors or system design flaws. We describe how we used MET calls to systematically identify preventable adverse events in an academic tertiary care hospital, and describe our surveillance results.MethodsFor four weeks we collected standard information on consecutive MET calls. Within a week of the MET call, a multi-disciplinary team reviewed the information and rated the cause of the outcome using a previously developed rating scale. We classified the type and severity of the preventable adverse event.ResultsWe captured information on all 65 MET calls occurring during the study period. Of these, 16 (24%, 95% confidence interval [CI] 16%-36%) were felt to be preventable adverse events. The most common cause of the preventable adverse events was error in providing appropriate therapy despite an accurate diagnosis. One service accounted for a disproportionate number of preventable adverse events (n = 5, [31%, 95% CI 14%-56%]).ConclusionsOur method of reviewing MET calls was easy to implement and yielded important results. Hospitals maintaining an MET can use our method as a preventable adverse event detection system at little additional cost.

Project description:BACKGROUND: Adverse events (AEs) are adverse outcomes caused by medical care. Several studies have indicated that a substantial number of patients experience AEs before or during hospitalization. However, few data describe AEs after hospital discharge. We determined the incidence, severity, preventability and ameliorability of AEs in patients discharged from the general internal medicine service of a Canadian hospital. METHODS: At a multisite Canadian teaching hospital, we prospectively studied patients who were consecutively discharged home or to a seniors' residence from the general internal medicine service during a 14-week interval in 2002. We used telephone interview and chart review to identify outcomes after discharge. Two physicians independently reviewed each outcome to determine if the patient experienced an AE. The severity, preventability and ameliorability of all AEs were classified. RESULTS: During the study period, outcomes were determined for 328 of the 361 eligible patients, who averaged 71 years of age (interquartile range 54-81 years). After discharge, 76 of the 328 patients experienced at least 1 AE (overall incidence 23%, 95% confidence interval [CI] 19%-28%). The AE severity ranged from symptoms only (68% of the AEs) or symptoms associated with a nonpermanent disability (25%) to permanent disability (3%) or death (3%). The most common AEs were adverse drug events (72%), therapeutic errors (16%) and nosocomial infections (11%). Of the 76 patients, 38 had an AE that was either preventable or ameliorable (overall incidence 12%, 95% CI 9%-16%). INTERPRETATION: Approximately one-quarter of patients in our study had an AE after hospital discharge, and half of the AEs were preventable or ameliorable.

Project description:ObjectiveTo estimate the incidence of adverse drug events (ADEs) associated with health care visits among U.S. adults across all ambulatory settings.Data sourceWe analyzed data from two nationally representative probability sample surveys: the National Ambulatory Medical Care Survey and the National Hospital and Ambulatory Medical Care Survey. From 2005 to 2007, the presence of an ADE was specifically defined, requested, and recorded in these surveys.Study designSecondary data analysis.Principal findingsAn estimated 13.5 million ADE-related visits occurred between 2005 and 2007 (0.5 percent of all visits), the large majority (72 percent) occurring in outpatient practice settings, and the remaining in emergency departments. Older patients (age ≥65 years) had the highest age-specific ADE rate, 3.8 ADEs per 10,000 persons per year. In adjusted analyses of outpatient visits, there was an increased odds of an ADE-related visit with increased medication burden (odds ratio [OR] for six to eight medications compared with no medications, OR 3.83 [2.20, 6.65]), and increased odds of ADEs associated with primary care visits compared with specialty visits (OR 2.22 [1.70, 2.89]).ConclusionsApproximately 4.5 million ambulatory visits related to ADEs occur each year, the majority of these in outpatient office practices. A greater focus on ADE prevention and detection is warranted among patients receiving multiple medications in primary care practices.

Project description:ObjectivesThe aim of this study was to clarify the characteristics of adverse events/near misses during laparoscopic/thoracoscopic surgery.MethodsUsing relevant key words for minimally invasive surgeries, 540 records were identified in the database of the Japan Council for Quality Health Care. After data review and the classification of adverse events, 746 events associated with laparoscopic (laparo group) and/or thoracoscopic (thoraco group) surgery were identified. We calculated the frequency of each event, compared the frequency regarding recurrent events, and evaluated the types of event that had resulted in deaths between the 2 groups.ResultsThere were 582 events in the laparo group, 159 in the thoraco group, and 5 in those undergoing combined surgery. Overall, injury of other organs (11.4%, 85/746), retention of a foreign body (9.1%, 68/746), breakage/failure of medical equipment or devices (6.2%, 46/746), massive bleeding (5.9%, 44/746), misperception of anatomy (5.6%, 42/746), and vascular injury (4.8%, 36/746) were frequently reported. There were marked differences in the frequency of injury of other organs (laparo group: 13.4%, 78/582; thoraco group: 4.4%, 7/159), massive bleeding (laparo group: 3.4%, 20/582; thoraco group: 14.5%, 23/159), and vascular injury (laparo group: 2.6%, 15/582; thoraco group: 12.6%, 20/159) between the 2 groups. Among the 56 patient-death reports, 132 adverse events were identified. In the thoraco group, bleeding events were frequently observed, whereas in the laparo group, various categories of events were noted.ConclusionsWe observed recurrent incidents and differences in the frequency between the 2 groups. Surgeons should keep in mind these characteristics. Retention of a foreign body and the breakage/malfunctioning of instruments might be reduced by the introduction of specialized checklists.

Project description:Our objective was to describe the prevalence and nature of adverse medical device events (AMDEs) in tertiary care children's hospitals. In our retrospective cohort study of patients at 44 children's hospitals in the Pediatric Health Information System (PHIS), we included all inpatient stays with an AMDE-related diagnosis from January 1, 2004 to December 31, 2011. We identified AMDEs by diagnoses that specified a device in their definition. We included events present on admission as well as those complicating hospital stays. We described the characteristics of these admissions and patients, and stratified analysis by device category and presence of a complex chronic condition. Of 4,115,755 admissions in the PHIS database during the study period, 136,465 (3.3%) had at least 1 AMDE. Vascular access and nervous system devices together represented 44.4% of pediatric AMDE admissions. The majority (75.5%) of AMDE admissions were of children with complex chronic conditions. The most common age group was patients aged 2 years or less at the time of their first AMDE-related admission. AMDEs occur commonly in a population cared for in tertiary children's hospitals. Research to more specifically delineate AMDEs and their predictors are next steps to understand and improve device safety in children.

Project description:PurposeRadiation oncology relies on rapidly evolving technology and highly complex processes. The US Food and Drug Administration collects reports of adverse events related to medical devices. We sought to characterize all events involving radiation oncology devices (RODs) from the US Food and Drug Administration's postmarket surveillance Manufacturer and User Facility Device Experience (MAUDE) database, comparing these with non-radiation oncology devices.Methods and materialsMAUDE data on RODs from 1991 to 2015 were sorted into 4 product categories (external beam, brachytherapy, planning systems, and simulation systems) and 5 device problem categories (software, mechanical, electrical, user error, and dose delivery impact). Outcomes included whether the device was evaluated by the manufacturer, adverse event type, remedial action, problem code, device age, and time since 510(k) approval. Descriptive statistics were performed with linear regression of time-series data. Results for RODs were compared with those for other devices by the Pearson χ2 test for categorical data and 2-sample Kolmogorov-Smirnov test for distributions.ResultsThere were 4234 ROD and 4,985,698 other device adverse event reports. Adverse event reports increased over time, and events involving RODs peaked in 2011. Most ROD reports involved external beam therapy (50.8%), followed by brachytherapy (24.9%) and treatment planning systems (21.6%). The top problem types were software (30.4%), mechanical (20.9%), and user error (20.4%). RODs differed significantly from other devices in each outcome (P<.001). RODs were more likely to be evaluated by the manufacturer after an event (46.9% vs 33.0%) but less likely to be recalled (10.5% vs 37.9%) (P<.001). Device age and time since 510(k) approval were shorter among RODs (P<.001).ConclusionsCompared with other devices, RODs may experience adverse events sooner after manufacture and market approval. Close postmarket surveillance, improved software design, and manufacturer-user training may help mitigate these events.

Project description:OBJECTIVE: To assess the association between Medicaid-induced financial stress of a hospital and the probability of an adverse medical event for a pediatric discharge. DATA SOURCES: Secondary data from the Nationwide Inpatient Sample, Agency for Healthcare Research and Quality's Healthcare Cost and Utilization Project, and the American Hospital Association's Annual Survey of Hospitals. Study examines 985,896 pediatric discharges (children age 0-17), from 1,050 community hospitals in 26 states (representing 63 percent of the U.S. Medicaid population) between 2005 and 2007. STUDY DESIGN: We estimate the probability of an adverse event, controlling for patient, hospital, and state characteristics, using an aggregated, composite measure to overcome rarity of individual events. PRINCIPAL FINDINGS: Children in hospitals with relatively high proportions of pediatric discharges that are more reliant on Medicaid reimbursement are more likely than children in other hospitals (odds ratio = 1.62) to experience an adverse event. Medicaid pediatric inpatients are more likely than privately insured patients (odds ratio = 1.10) to experience an adverse event. CONCLUSIONS: Hospital reliance on comparatively low Medicaid reimbursement may contribute to the problem of adverse medical events for hospitalized children. Policies to reduce adverse events should account for differences in underlying, contributing factors of these events.

Project description:IntroductionIndividual and organizational response to an adverse event is a key part of the life cycle of a patient safety event. Just culture is a safety concept that emphasizes system drivers of human behavior. We developed a learning activity for medical students to teach and discuss just culture as part of a patient safety curriculum.MethodsThis small-group, discussion-based learning activity was aimed at third-year medical students. Over 5 years, 628 students participated in it. The session had three components: a presession case-based survey, a didactic lecture, and a facilitated small-group discussion. Participants evaluated the session using our institution's standard learner assessment. They also took a postcourse test that contained multiple-choice questions relating to the session.ResultsOn a 5-point Likert scale (1 = poor, 3 = good, 5 = excellent), students rated the large-group lecture (3.2) and small-group discussion (3.2) moderately. Over 85% of students answered all knowledge items on a course posttest correctly.DiscussionThis learning activity provides an easy-to-implement case-based discussion to introduce the concepts of just culture.

Project description:Background Life expectancy in the United States has recently declined, in part attributable to premature cardiometabolic mortality. We characterized national trends in premature cardiometabolic mortality, overall, and by race-sex groups. Methods and Results Using death certificates from the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research, we quantified premature deaths (<65 years of age) from heart disease, cerebrovascular disease, and diabetes mellitus from 1999 to 2018. We calculated age-adjusted mortality rates (AAMRs) and years of potential life lost (YPLL) from each cardiometabolic cause occurring at <65 years of age. We used Joinpoint regression to identify an inflection point in overall cardiometabolic AAMR trends. Average annual percent change in AAMRs and YPLL was quantified before and after the identified inflection point. From 1999 to 2018, annual premature deaths from heart disease (117 880 to 128 832), cerebrovascular disease (18 765 to 20 565), and diabetes mellitus (16 553 to 24 758) as an underlying cause of death increased. By 2018, 19.7% of all heart disease deaths, 13.9% of all cerebrovascular disease deaths, and 29.1% of all diabetes mellitus deaths were premature. AAMRs and YPLL from heart disease and cerebrovascular disease declined until the inflection point identified in 2011, then remained unchanged through 2018. Conversely, AAMRs and YPLL from diabetes mellitus did not change through 2011, then increased through 2018. Black men and women had higher AAMRs and greater YPLL for each cardiometabolic cause compared with White men and women, respectively. Conclusions Over one-fifth of cardiometabolic deaths occurred at <65 years of age. Recent stagnation in cardiometabolic AAMRs and YPLL are compounded by persistent racial disparities.
