In 1981 the Army initiated training in Emergency Medicine for Physician Assistants. The training was in response to an Army wide Emergency Medicine physician shortage. PAs were trained to augment physician staff in the perpetually busy emergency departments. Most assignments were to understaffed military hospitals located throughout the United States.

Selected PAs were enrolled in a training program at Darnall Army Community Hospital, Fort Hood Texas, which already had an existing emergency medicine physician residency. The program of study was twelve months long and paralleled the second post graduate year training for emergency physicians. However, suffering a severe PA shortage in line units and PA retention dropping, the Army reduced or stopped most post-graduate training for PAs in 1986. A total of twelve EMPAs were trained during those five years.

In 1989 the American College of Emergency Physicians published a position paper in the Annals of Emergency Medicine on the utilization of PAs in military emergency medicine.¹While there was some division among physicians as to the practicality of utilizing PAs in emergency medicine, the authors made the important point that the training of PAs in this field prepared them for the type of trauma that could be anticipated in combat.²The authors stress that PAs should be used as physician extenders and not as a physician substitute. The article maintained that EMPAs could be a valuable asset to a military emergency department. The college advocated that all EMPAs should receive a formal course of training in either a fellowship or residency program for at least twelve months and that the training should be conducted at an already approved emergency medicine physician residency program.

In 1991, the Army Surgeon General approved a plan for a revised program. The first formal EMPA residency course began at Brooke Army Medical Center, Ft. Sam Houston, Texas on 1 July 1991. In 1992, a second program was established at Madigan Army Medical Center, Tacoma, Washington and in 1995 the EMPA program at Darnall Army Community Hospital, Ft. Hood Texas was re-opened. All three training sites have active emergency medicine physician residencies. Upon successful completion and graduation from EMPA training the graduates are awarded the M2 identifier (65DM2).
