S ociety's increasing expectations and the transition from traditional to regional bureaucracies, combined with advances in medicine, pressure physicians into increasing their teaching and research commitments and into becoming more involved in administrative functions. In addition to their clinical duties, many physicians have taken on varying amounts of teaching, research, and administrative duties (1-4). Further, the practice of medicine has always intruded on physicians' personal lives, particularly in rural areas and where there are few specialists. Consequently, the organization of medical practice has shifted toward group practice and clinical decision making has evolved from highly independent consultations to the sharing of expertise (5,6).
