The medical-psychiatric unit: a novel psychosomatic approach.

A retrospective chart review of 600 general hospital patients, of whom 200 had been admitted to a medical-psychiatric unit, 200 to a conventional psychiatric unit and 200 to medical-surgical units, and for whom psychiatric consultation had been requested, disclosed significant differences in the patient populations of these services. The data suggest that consultation psychiatry and medical-psychiatric units serve two different subgroups of patients with combined physical and psychiatric illness. A comprehensive model of clinical psychosomatic medicine encompassing consultation psychiatry, liaison psychiatry, medical-psychiatric units and after-care medical-psychiatric clinics, is proposed.
