Psychiatric consultation to a general hospital medical evaluation service.

Psychiatric consultation to a general hospital medical evaluation service was reviewed and compared with consultation patterns for general hospital inpatients and psychiatric emergency service patients. Results of a questionnaire survey indicated nearly 1 in 5 patients admitted to this acute medical service (24-hour maximum stay) required psychiatric consultation. A study of those patients seen by psychiatric consultants is reported. The prevalence of depressive illness as well as the psychiatric hospitalization referral rate was substantially greater than in general hospital inpatient or psychiatric emergency service evaluations. The implications of this relatively new area of consultation-liaison for hospital staffing and medical education are discussed.
