Abstract
The objective of this study was to determine the impact of Emergency Medicine (EM) faculty presence on timely thrombolytic therapy for acute myocardial infarction in the Emergency Department (ED). We performed a retrospective study of data regarding acute myocardial infarction patients in the ED of a large urban teaching hospital. Data were collected from January 1, 1998 to December 31, 1999 when EM faculty were not present in the ED and from January 1, 2001 to December 31, 2002 when they were. We compared median time from patient arrival to thrombolytics, percent of patients receiving thrombolytics within 30 min of arrival, and percent of patients with indications for primary revascularization who received it before and after EM faculty presence. The results indicate that EM faculty presence resulted in a decrease in median time from arrival to thrombolytic administration of 17 min (95% CI: 9, 28). Before EM faculty presence, the median time was 44 min as compared to 24 min post-EM faculty presence. Patients received thrombolytic therapy within 30 min 25.8% of the time before EM faculty presence as compared to 65.4% with EM faculty presence; an absolute increase of 39.6% (95% CI: 23.0%, 56.3%). Primary revascularization occurred in 56.9% of eligible patients pre-EM faculty presence and 81.4% post-EM faculty presence; an increase of 24.5% (95% CI: 13.6%, 35.4%). We conclude that the introduction of Emergency Medicine faculty significantly improved the quality of care for acute myocardial infarction patients in a large urban Emergency Department.
