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.

In September 2006, the Centers for Disease Control and Prevention released its revised recommendations for human immunodeficiency virus (HIV) testing. Prominent among these were the recommendations that emergency departments should perform routine screening for HIV infection. ⋯ It contains the lessons that were learned when such a program was initiated at an academic emergency department. Consideration of these steps will help streamline the establishment of the program, but there should be careful consideration of the program's costs and sustainability before embarking on the process.

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.

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.

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.
