title: Evolution of Academic Emergency Medicine over a decade (1991-2001).
abstract: OBJECTIVE
  To test the hypothesis that emergency medicine (EM) has made significant, quantifiable progress within U.S. academic medicine over the past ten years, 1991-2001.
  
  
  METHODS
  Baseline (7/1/1991) and comparison (7/1/2001) data sets contained all Liaison Committee on Medical Education (LCME)-accredited schools, Association of Academic Chairs of Emergency Medicine (AACEM)-recognized academic departments of EM, Residency Review Committee (RRC)-accredited EM residencies, and Association of American Medical Colleges (AAMC)-designated academic medical centers. The increase over ten years in the two primary variables of academic departmental status, and EM residencies located at academic medical centers, was examined in the aggregate, then stratified by medical schools grouped by academic rank. Differences over time are expressed as simple proportions, bounded by 95% confidence intervals (95% CIs).
  
  
  RESULTS
  Between 1991 and 2001, the proportion of academic departments of EM at medical schools increased from 18% to 48% (95% CI for difference of 30% = 19% to 41%). The proportion of EM residencies at academic medical centers increased from 42% to 66% (95% CI for a difference of 24% = 11% to 36%). The largest increment of 37% (95% CI = 22% to 52%) in academic departments of EM, and of 36% (95% CI = 20% to 52%) in EM residencies located at academic medical centers, occurred within medical schools whose academic rank was above the median.
  
  
  CONCLUSIONS
  A quantitatively and statistically significant increase in academic departments of EM within medical schools and EM residency programs at academic medical centers has occurred over the past decade. Half of all medical schools now have academic departments of EM, and two-thirds of academic medical centers house EM residency programs. This has taken place largely within institutions whose academic ranking places them among the top half of all U.S. medical schools.
