Training military physicians in trauma management is a dilemma in peacetime, since there are few opportunities to gain clinical experience within the military care system. This program provides experience in clinical decision making through case simulation. Five cases, of increasing difficulty, are presented in a single videodisc side. The program is implemented on a system based on the IBM PC, and is written in the C programming language. The program emphasizes clinical realism by providing many clinical options at each decision point, and by audiovisually depicting combat clinical care in very realistic ways. The user interface is flexible and, though complex, is easy to use; it is supported by a narrated, on-line tutorial.
