Consultation liaison psychiatry within the general hospital: referral pattern and management.

The emergence of consultation psychiatry as an important psychiatric subspecialty is in part due to the siting of psychiatric units in general hospitals, the manifest advances in medical technology and the increasing elderly population needing specialist care. This paper describes an evaluation of all referrals to a liaison psychiatry unit in a 550 bed general hospital over a six month period. 205 requests for psychiatric consultation were received, which represented 2% of all admissions. There was considerable variation between departments with regard to the referral rate. Management most often consisted of advice, with over 50% of patients being subsequently referred for ongoing psychiatric care.
