Accurate diagnosis in emergency department patients with possible myocardial ischemia is problematic. Two-dimensional echocardiography has a high sensitivity for identifying patients with myocardial infarction (MI); however, few studies have investigated its diagnostic ability when used acutely in ED patients with possible myocardial ischemia. Therefore we investigated the ability of ED echocardiography for predicting cardiac events in patients with possible myocardial ischemia. ⋯ Echocardiography performed in ED patients with possible myocardial ischemia identifies those who will have cardiac events, is more sensitive than the ECG, and has significant incremental value when added to baseline clinical variables and the ECG.

Numerous clinical guidelines have been promoted to help improve the management of acute injury and illness. In November 1997, the National Asthma Education and Prevention Program released the final version of its comprehensive second Expert Panel Report, designed to distill scientific advances in asthma care and provide a set of practical tools to help guide clinician and patient decisions. The panel's recommendations for acute asthma care stress the use of the objective measures of pulmonary function to assess severity, aggressive inhaled beta 2-agonist therapy, early systemic corticosteroid administration, and early disposition decisions. This article provides a focused overview of the 146-page document and highlights aspects of the new guidelines of particular importance to emergency physicians.

Emergency medicine has progressed significantly since its initial recognition as a medical specialty. Relatively little factual information is known, however, regarding who or how many physicians practice emergency medicine. The purpose of this study is to determine the total number of physicians practicing clinical emergency medicine during a specified period, to describe certain characteristics of those individuals, and to estimate the total number of full-time equivalents (FTEs), as well as the total number of individuals needed to staff those FTEs. ⋯ Given that there are 4,945 hospitals with EDs and given that the data indicate there are 4.96 FTEs per ED, the total number of FTEs is projected to be 24,548 (standard error = 437). Given further that the data indicate a physician/FTE ratio of 1.51:1, we conclude that there are 36,990 persons (standard error = 683) needed to staff those FTEs. When adjusted for persons working at more than one ED, that number is reduced to 32,026.
