Primary objective: To determine the incidence and epidemiology of emergency department (ED)-attended mild traumatic brain injury (mTBI) in the US.

Background Despite over a decade of efforts to reduce the adverse event rate in healthcare, the rate has remained relatively unchanged. Root cause analysis (RCA) is a process used by hospitals in an attempt to reduce adverse event rates; however, the outputs of this process have not been well studied in healthcare. This study aimed to examine the types of solutions proposed in RCAs over an 8-year period at a major academic medical institution. Methods All state-reportable adverse events were gathered, and those for which an RCA was performed were analysed. A consensus rating process was used to determine a severity rating for each case. A qualitative approach was used to categorise the types of solutions proposed by the RCA team in each case and descriptive statistics were calculated. Results 302 RCAs were reviewed. The most common event types involved a procedure complication, followed by cardiopulmonary arrest, neurological deficit and retained foreign body. In 106 RCAs, solutions were proposed. A large proportion (38.7%) of RCAs with solutions proposed involved a patient death. Of the 731 proposed solutions, the most common solution types were training (20%), process change (19.6%) and policy reinforcement (15.2%). We found that multiple event types were repeated in the study period, despite repeated RCAs. Conclusions This study found that the most commonly proposed solutions were weaker actions, which were less likely to decrease event recurrence. These findings support recent attempts to improve the RCA process and to develop guidance for the creation of effective and sustainable solutions to be used by RCA teams.

Introduction Alzheimer's disease and related dementias (ADRD) disproportionately impact racial and ethnic minority and socioeconomically disadvantaged adults. Yet, these populations are significantly underrepresented in research. Methods We systematically reviewed the literature for published reports describing recruitment and retention of individuals from underrepresented backgrounds in ADRD research or underrepresented participants' perspectives regarding ADRD research participation. Relevant evidence was synthesized and evaluated for quality. Results We identified 22 eligible studies. Seven studies focused on recruitment/retention approaches, all of which included multifaceted efforts and at least one community outreach component. There was considerable heterogeneity in approaches used, specific activities and strategies, outcome measurement, and conclusions regarding effectiveness. Despite limited use of prospective evaluation strategies, most authors reported improvements in diverse representation in ADRD cohorts. Studies evaluating participant views focused largely on predetermined explanations of participation including attitudes, barriers/facilitators, education, trust, and religiosity. Across all studies, the strength of evidence was low. Discussion Overall, the quantity and quality of available evidence to inform best practices in recruitment, retention, and inclusion of underrepresented populations in ADRD research are low. Further efforts to systematically evaluate the success of existing and emergent approaches will require improved methodological standards and uniform measures for evaluating recruitment, participation, and inclusivity.

Context Although stroke centers are widely accepted and supported, little is known about their impact on patient outcomes. Objective To examine the association between admission to stroke centers for an acute ischemic stroke and mortality. Design, Setting, and Participants Observational study using data from the New York Statewide Planning and Research Cooperative System. We compared mortality for patients admitted with acute ischemic stroke (n=30,947) between 2005 and 2006 at designated stroke centers and non-designated hospitals using differential distance to hospitals as an instrumental variable to adjust for potential pre-hospital selection bias. Patients were followed for mortality for 1 year after the index hospitalization through 2007. To assess whether our findings were specific to stroke, we also compared mortality for patients admitted with gastrointestinal hemorrhage (n=39,409) or acute myocardial infarction (n=40,024) at designated stroke centers and non-designated hospitals. Main Outcome Measure Thirty-day all-cause mortality. Results Among 30,947 patients with acute ischemic stroke, 15,297 (49.4%) were admitted to designated stroke centers. Using the instrumental variable analysis, admission to designated stroke centers was associated with greater use of thrombolytic therapy (4.8% vs. 1.7%; adjusted difference 2.2%, 95% CI, 1.6% to 2.8%; P<0.001) and lower 30-day all-cause mortality (10.1% vs. 12.5%; adjusted mortality difference: −2.5%, 95% CI, −3.6% to −1.4%; P<0.001). Differences in mortality also were observed at all time points, including at 1-day, 7-day, and 1-year follow-up. Moreover, the outcome differences were specific to stroke, as stroke centers and non-stroke centers had similar 30-day all-cause mortality rates among those with acute myocardial infarction (adjusted mortality difference: +0.3%, 95% CI, −0.5% to 1.0%; P=0.50) and/or gastrointestinal hemorrhage (adjusted mortality difference: +0.1%, 95% CI, −0.9% to 1.1%; P=0.83). Conclusions Admission to a designated stroke center for acute ischemic stroke was associated with more frequent use of thrombolytic therapy and lower mortality.

Objective There is an absence of nationally representative data describing pediatric patients who use emergency medical services (EMS) and the factors associated with EMS use by children. This study characterizes pediatric emergency department (ED) visits for which the patient arrived by EMS and identifies factors associated with those visits using a nationally representative database. Methods A secondary analysis of the ED component of the 1997–2000 National Hospital Ambulatory Medical Care Survey was performed. The dependent variable was the mode of arrival to the ED (EMS vs. not EMS), and independent variables were grouped into four domains: demographic, clinical, system, and service characteristics. Bivariate analyses and multivariate logistic regression analyses were conducted. Results There were 110.9 million ED visits by children aged <19 years between 1997 and 2000. Pediatric patients constituted 27.3% of all ED visits during this time, and 7.9 million (7.1%) of these patients arrived via EMS. Pediatric patients represented 13% of all EMS transports. The annual EMS utilization rate by children was 26 per 1,000, compared with 66 per 1,000 in the adult population (p < 0.001). Sixteen percent of children transported by EMS were admitted to the hospital. Sixty-two percent of pediatric patients arriving at the ED by EMS were transported as a result of injury or poisoning. Characteristics significantly associated with arrival by EMS in the final multivariate model included demographic (age, African American race, urban residence), clinical (need for greater immediacy of care, illnesses associated with certain diagnoses), and service (greater number of diagnostic services) variables. Conclusions Pediatric patients transported by EMS are more likely to have injuries and poisoning, and have higher-acuity illness than those arriving at the ED by other means. The epidemiology of pediatric EMS use may have important operational, training, and public health implications and requires further study.

BACKGROUND/OBJECTIVES The Emergency Department (ED) is an important source of health care for nursing home residents. The objective of this study was to characterize ED use by nursing home residents in the United States (US). DESIGN Analysis of the National Hospital Ambulatory Medical Care Survey SETTING US Emergency Departments, 2005-2008 PARTICIPANTS Individuals visiting US EDs, stratified by nursing home and non-nursing home residents. INTERVENTIONS None MEASUREMENTS We identified all ED visits by nursing home residents. We contrasted the demographic and clinical characteristics between nursing home residents and non-nursing home residents. We also compared ED resource utilization, length of stay and outcomes. RESULTS During 2005-2008, nursing home residents accounted for 9,104,735 of 475,077,828 US ED visits (1.9%; 95% CI: 1.8-2.1%). The annualized number of ED visits by nursing home residents was 2,276,184. Most nursing home residents were elderly (mean 76.7 years, 95% CI: 75.8-77.5), female (63.3%), and non-Hispanic White (74.8%). Compared with non-nursing home residents, nursing home residents were more likely have been discharged from the hospital in the prior seven days (adjusted OR 1.4, 95% CI: 1.1-1.9). Nursing home residents were more likely to present with fever (adjusted OR 1.9; 95% CI: 1.5-2.4) or hypotension (systolic blood pressure ≤90 mm Hg, OR 1.8; 95% CI: 1.5-2.2). Nursing home patients were more likely to receive diagnostic test, imaging and procedures in the ED. Almost half of nursing home residents visiting the ED were admitted to the hospital. Compared with non-nursing home residents, nursing home residents were more likely to be admitted to the hospital (adjusted OR 1.8; 95% CI 1.6-2.1) and to die (adjusted OR 2.3; 95% CI 1.6-3.3). CONCLUSIONS Nursing home residents account for over 2.2 million ED visits annually in the US. Compared with other ED patients, nursing home residents have higher medical acuity and complexity. These observations highlight the national challenges of organizing and delivering ED care to nursing home residents in the US.
