Psychiatric consultation: concepts and controversies.

There are two major models of consultation in the field of psychiatry, differing in their goals, participants, settings, and methods. The psychiatric-therapeutic model entails provision of optimal care for the individual patient; the community mental health model involves provision of assistance to mental health caregivers. The author believes that to enhance the value of consultation the consultation should restrict his or her role to that for which he or she has been trained. Current social needs, coupled with a limited supply of consultants, suggest that psychiatric consultation should be provided within comprehensive health care systems. There is a pressing need to clarify the concepts of formulations concerning the criteria of outcome of psychiatric consultation so that evaluation of its effectiveness can be advanced.
