title: Geropsychiatric consultation in a general hospital in Taiwan.
abstract: The aim of this study was to characterize clinically significant issues in a psychiatric consultation service for geriatric inpatients in a general hospital in Taiwan. This was a case-control study. During a 5-month period, 100 geriatric (age > or =65 years) inpatients consecutively referred for consultation-liaison psychiatric service from non-psychiatric departments formed the study group. Another 100 medical inpatients, also referred for consultation-liaison to the psychiatric service, but aged 17-50, formed the control (non-geriatric) group. The diagnosis, demography, reason for referral, symptomatology, and other clinical characteristics were determined by consensus between two psychiatrists. Psychiatric diagnosis was made according to criteria in the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders. The geropsychiatric consultation rate was 0.9%. Geriatric patients constituted 20.1% of all psychiatric referrals. Common reasons for referral of geriatric inpatients were confusion (32%), depression (17%), disturbing behaviors (14%), and psychosis (14%). The most common psychiatric disorder among geriatric patients was an organic mental disorder (79%), followed by a depressive disorder (13%). More geriatric patients suffered from cancers and cerebrovascular diseases than non-geriatric patients. The geriatric group was more likely to have multiple physical illnesses. Organic mental disorder and depressive disorders are the most common psychiatric diagnoses in the geropsychiatric consultation service of the authors. In the authors' experience, both psychotropic medication treatment and psychosocial intervention are important in geropsychiatric consultation.
