An emergency medicine (EM) clerkship can provide a medical student with a unique educational experience. The authors sought to describe the current experiential curriculum of the EM clerkship, along with methods of evaluation, feedback, and grading. ⋯ Medical students are exposed to a variety of didactic lectures and procedure labs but have similar experiences regarding shift length and work hours. Methods of evaluation of clinical performance vary across clinical sites.

Randomized Controlled Trial
Determination of the effect of in vitro time, temperature, and tourniquet use on whole blood venous point-of-care lactate concentrations.
The authors sought to determine the effect of in vitro time, temperature, and removable tourniquet use on changes in venous point-of-care lactate concentrations. ⋯ Whole blood point-of-care lactate concentrations in healthy subjects do not change significantly over 15 minutes at either -1 degrees C or 23 degrees C, and the use of a tourniquet has no appreciable effect on lactate concentrations.

Comparative Study
Prospective study of the clinical features and outcomes of emergency department patients with delayed diagnosis of pulmonary embolism.
The authors hypothesized that emergency department (ED) patients with a delayed diagnosis of pulmonary embolism (PE) will have a higher frequency of altered mental status, older age, comorbidity, and worsened outcomes compared with patients who have PE diagnosed by tests ordered in the ED. ⋯ In this single-center study, the diagnosis of PE was frequently delayed and outcomes of patients with delayed diagnosis were worse than those of patients with PE diagnosed in the ED.

Despite its importance in improving patient care, the state of published emergency medicine (EM) research is poorly understood. The countries of origin, methodological characteristics, sources of funding, and ongoing trends in this research are unknown. Knowledge of these characteristics has important policy, research, and clinical implications for academic EM. ⋯ Emergency medicine research output is increasing worldwide. The United States is the largest producer of EM research, only a small fraction of which is supported by the NIH. The majority of research published by emergency researchers is published in non-EM journals.

Randomized Controlled Trial Comparative Study
Can untrained laypersons use a defibrillator with dispatcher assistance?
Automated external defibrillators (AEDs) provide an opportunity to improve survival in out-of-hospital cardiac arrest by enabling laypersons not trained in rhythm recognition to deliver lifesaving therapy. This study was performed to examine whether untrained laypersons could safely and effectively use these AEDs with telephone-guided instructions and if this action would compromise the performance of cardiopulmonary resuscitation (CPR) during a simulated ventricular fibrillation out-of-hospital cardiac arrest. ⋯ The quality of dispatcher-assisted CPR is poor. Dispatcher assistance in defibrillation by a layperson not trained to use an AED seems feasible and does not compromise the performance of CPR.
