Emergency medicine became the twenty-third specialty by the American Board
of Medical Examiners in 1979. Emergency physicians are specialists in the s
tabilization and resuscitation of medical and surgical emergencies in patie
nts of all ages; they are experts in triage and in prioritization of resour
ces. Emergency physicians provide the "safety net" for the American health
care system, and they are the facilitators between the community and health
care systems, and between primary care physicians and specialists. The eme
rgency department is an ideal environment in which to teach the assessment
and management of patients presenting with undifferentiated processes. Emer
gency physicians possess a unique set of clinical and research skills that
have made them valuable members of the medical school academic community. P
resented is a historical perspective on the specialty of emergency medicine
and its evolving role at the Mount Sinai School of Medicine. Included are
discussions on innovations in teaching developed by the emergency medicine
faculty including applications of computer-assisted instruction and the Int
ernet.
