The specialty of emergency medicine has expanded in many dimensions over the past 50 years. First and most dramatic is simply the magnitude of care that emergency departments (EDs) now provide. The volume of patients visiting EDs in the United States has increased to more than 117 million per year (39.4 per 100 population).1 The duration and extent of care provided in EDs are likewise increasing as hospital inpatient capacity is reached and patients in EDs receive prolonged care while awaiting inpatient beds. In addition, the constraints on the health care system continue to increase and the ED, which is always open and will necessarily see all comers, is becoming the portal of entry for a wider spectrum of patients.
