The field of international emergency medicine (IEM) has grown rapidly over the past several decades, with a rise in the number of IEM fellowship positions, sustained growth in the international sections of major emergency medicine organizations, and an increase in the range of topics included under its rubric. One of the greatest obstacles to the continued growth of IEM remains the lack of a high-quality, consolidated, and easily accessible evidence base of literature. ⋯ Research articles were selected for the review according to explicit, predetermined criteria that included both methodological quality and perceived impact of the research. It is the authors' hope that this annual review will act as a forum for disseminating best practices while also stimulating further research in the field of IEM.

The significance of medical errors is widely appreciated. Given the frequency and significance of errors in medicine, it is important to learn how to reduce their frequency; however, the identification of factors that increase the likelihood of errors poses a considerable challenge. The National Emergency Department Safety Study (NEDSS) sought to characterize organizational- and clinician-associated factors related to the likelihood of errors occurring in emergency departments (EDs). ⋯ NEDSS also examined the characteristics of EDs associated with the occurrence of errors. NEDSS is the first comprehensive national study of the frequency and types of medical errors in EDs. This article describes the methods used to develop and implement the study.

Patient safety interventions for multitasking, multipatient, error-prone work settings such as the emergency department (ED) must improve assorted clinical abilities, specific cognitive strategies, and teamwork functions of the staff to be effective. Multiple encounter simulation scenarios explore and convey this specialized mental work-set through use of multiple high-fidelity medical simulation (SIM) manikins in realistic surroundings. Multipatient scenarios reflect the work situations being targeted yet have the benefit of scripted control and instructor guidance to advance specific educational objectives. ⋯ Widespread and effective training in well-replicated, carefully coordinated representations of complex multipatient work environments may strengthen educational interventions for personnel working in high acuity and work-overloaded settings such as the ED. The use of concurrent patient encounter SIM exercises to elicit calculated stressors and to foster compensatory staff behaviors is an educational advance toward this objective. The authors present SIM methodology using concurrent patient encounters to replicate these environments.

Infection with the human immunodeficiency virus (HIV) continues to expand in nontraditional risk groups, and the prevalence of undiagnosed infection remains relatively high in the patient populations of urban emergency departments (EDs). Unfortunately, HIV testing in this setting remains uncommon. The objectives of this study were 1) to develop a physician-based diagnostic rapid HIV testing model, 2) to implement this model in a high-volume urban ED, and 3) to prospectively characterize the patients who were targeted by physicians for testing and determine the proportions who completed rapid HIV counseling, testing, and referral; tested positive for HIV infection; and were successfully linked into medical and preventative care. ⋯ A physician-based diagnostic HIV testing model was developed, successfully implemented, and sustained in a high-volume, urban ED setting. While the use of this model successfully identified patients with undiagnosed HIV infection in the ED, the overall level of testing remained low. Innovative testing programs, such as nontargeted screening, more specific targeted screening, or alternative hybrid methods, are needed to more effectively identify undiagnosed HIV infection in the ED patient population.

The effectiveness of out-of-hospital regionalization of ST-elevation myocardial infarction (STEMI) patients to hospitals providing primary percutaneous coronary intervention depends on the accuracy of the out-of-hospital 12-lead electrocardiogram (PHTL). Although estimates of sensitivity and specificity of PHTL for STEMI have been reported, the impact of out-of-hospital STEMI prevalence on positive predictive value (PPV) has not been evaluated. ⋯ Even when assuming high specificity for PHTL, the false-positive rate will be considerable if applied to a population at low risk for STEMI. Before broadening application of PHTL to low-risk patients, the implications of a high false-positive rate should be considered.
