Perhaps the greatest operational problem faced by the New York City Emergency Medical Service (EMS) today is the sheer volume of calls entering the system, and the fact that many of those requests for medical aid are not life-threatening emergencies requiring ambulance transport. This creates two situations that New York City is all too familiar with: (l) ambulances are not available for true emergencies; and (2) response times for ambulances to arrive at the scene of an emergency are extended.

A four-month pilot “on-scene triage” program was initiated by EMS as a possible solution to these problems. The program ran from May to August of 1980. A marked EMS car was designated as the “Triage Car” and was in operation during those hours when ambulance requests were at their peak (usually two to ten PM).
