Abstract
Consultaion-liaison activities as an inpatient service at Juntendo University Hospital were studied. For the last 3 years, 91 inpatients (35 men and 56 women, mean age : 47.8 years old) took our psychiatric treatment. All services except those of anesthesia requested our consultation. The main reasons for consultation were psychomotor-excitement (24.2%), symptoms based on a mental illness (20.9%) and depressive symptoms (17.6%). Patients with a mental illness had been treated as psychiatric outpatients before this admission. The consulted patients were diagnosed with acute organic brain syndrome (delirium) (22.0%), psychogenic reaction (20.9%), and schizophrenia (12.1). The psychiatric symptoms first appeared after the admission in most of them (79.1%).
