The setting was an urban, inner city teaching hospital. After providing informed consent, subjects were randomized into two arms: those watching a 12-min educational video on stroke developed by the American Stroke Association (video group) and those not undergoing an intervention (control group). Both groups were administered a 13-question quiz covering different stroke-related issues, but only the video group received this same test again after the completion of the educational program. Those enrolled were contacted after 1 month to determine knowledge retention via the same test. Immediately after watching the educational program, participants demonstrated improved knowledge of stroke-related questions, with an increase of test scores from 6.7 +/- 2.5 to 9.5 +/- 2.6 (p < 0.01). Even at the 1-month follow-up, the video group had significantly higher test scores than the control group. A stroke educational videotape improves the knowledge of this dangerous disease and may be a valuable and relatively low-cost tool for focused patient education in the Emergency Department waiting room.

To determine if authorship in EM publications has increased in parallel with this trend. The gender of first and last authors of EM articles in Academic Emergency Medicine, American Journal of Emergency Medicine, Annals of Emergency Medicine, and Journal of Emergency Medicine were examined. The authors reviewed articles from 1985, 1995, and 2005 for American Journal of Emergency Medicine, Annals of Emergency Medicine, and Journal of Emergency Medicine and from 1999 and 2005 for Academic Emergency Medicine. The primary outcomes were the proportions of female authors. A total of 2,016 articles were reviewed. Overall, 18% of first and last authors were female. Respectively, for 1985, 1995, 1999, and 2005, the proportions of female first authors were 9%, 15%, 19%, and 24%; the proportions of female last authors were 9%, 18%, 19%, and 22%. The trend of increases in female authorship was statistically significant. Although female authorship remains a minority in EM publications, it has increased significantly in parallel with increases in female participation in EM.

Our objective was to determine if the infusion rate of a single 18-g IV was equivalent to the infusion rate of two 20-g IVs. Methods: This was a prospective study in healthy adult volunteers. Subjects simultaneously received 500 mL of normal saline via an 18-g IV in one arm and 500 mL of normal saline via two 20-g IVs in the other arm. We measured the rates of fluid administration. Paired Student's t test was used for comparison of the 2 arms of the study. We estimated that 18 trials were needed in sample size analysis. Results: Eighteen trials were completed. The mean infusion rate for a single 18-g 500-mL IV administration was 35.6 mL/min (95% confidence interval [CI], 30.3-40.8), with manufacturer's rating being 105 mL/min. The mean infusion rate for two 20-g IVs was 41.3 mL/min (95% CI, 36.1-46.4), with manufacturer's rating being 120 mL/min. The rate of infusion via two 20-g IVs were statistically significantly faster than the single 18-g IV, with a mean difference in flow rate of 5.7 mL/min (95% CI, 1.3-10; P = .026). Conclusion: In healthy volunteers, administration of intravenous fluids through two 20-g IVs is faster than a single 18-g IV, although both approaches are markedly slower than the manufacturer's estimates.

However, there is no evidence supporting the optimal time or duration for an EM rotation, and a number of institutions offer third-year rotations. A recently published syllabus provides areas of knowledge, skills, and attitudes that third-year EM rotation directors can use to develop curricula. This article expands on that syllabus by providing a comprehensive curricular guide for the third-year medical student rotation with a focus on implementation. Included are consensus-derived learning objectives, discussion of educational methods, considerations for implementation, and information on feedback and evaluation as proposed by the Clerkship Directors in Emergency Medicine Third-Year Curriculum Work Group. External validation results, derived from a survey of third-year ro...
