Training programs in bedside ultrasound for emergency physicians often encounter considerable resistance, partly because of concern that the number of radiology-interpreted studies ordered from the ED may decrease. This study attempted to determine the effect of instituting an ED training program in ultrasound on the ordering of formal studies from a department of radiology. ⋯ The number of formal studies significantly increased after institution of the training program, both in terms of absolute numbers (annual mean 181 v 95, P < .001) and as a percentage of all outpatient sonograms ordered at the institution (9.8% v 5.1%, P < .001). Introduction of a teaching program in emergency ultrasound appears to increase utilization of formal ultrasound services, at least during the training period.

Drug dosage and appropriate size of medical equipment for emergency pediatric patients are determined by age, body weight and/or height. In an emergency situation, however, such information about the patients is not always clear. Body height is easily measured when the patient lies down supine. ⋯ We studied the reliability of this tape in pediatric anesthesia. Body weight estimated from the tape was accurate, and predicted size of ETT and LTD was appropriate. PES Tape is a reliable tool in pediatric emergency.

Animal research has provided important information about many aspects of the pathophysiology of human disease. Well-performed animal studies can determine the potential benefit of many proposed therapeutic interventions, and experimental results from animal studies have served as the basis for many landmark clinical trials. Many animal research models are described in the research literature, and choosing the appropriate model to answer a research question can be a daunting task. ⋯ This article was prepared by members of the SAEM Research Committee to provide an overview of animal modeling. Important considerations in choosing, applying, and developing animal research models are outlined. Practical discussions of potential problems with animal models are also provided.

A prospective, consecutive study was performed to determine if medical student supervision in the emergency department (ED) changes patient throughput time (ie, the time from triage to discharge). The mean patient throughput time on days when medical students were present in the ED (group 1) was compared to the mean patient throughput time on days when medical students were absent from the ED (group 2). Throughput time was measured in minutes. ⋯ The two groups were also compared for mean daily acuity (as gauged by mean daily number of patient admissions) and mean daily patient census. The differences in mean daily throughput times (group 1, 145.2 min v group II, 150.6 min; P = .40), mean daily census (group 1, 28.1 patients v group 2, 28.1 patients; P = .75), and mean daily admissions (group 1, 10.4 patients v group 2, 10.7 patients; P = .74) were all insignificant. Precepting medical students in this ED did not significantly change patient throughput times.

To describe interobserver variability among emergency medicine (EM) faculty when using global assessment (GA) rating scales and performance-based criterion (PBC) checklists to evaluate EM residents' clinical skills during standardized patient (SP) encounters. ⋯ When EM faculty evaluate clinical performance of EM residents during videotaped SP encounters, interobserver variabilities are similar, whether a PBC checklist or a GA rating scale is used.
