[Readmission among discharged psychiatric patients and it's correlates].
OBJECTIVE
This study investigated the incidence of readmission among discharged psychiatric patients and examined factors predicting early readmission.


METHODS
A cohort of 343 patients, who had been hospitalized involuntarily to mental hospitals for medical care and custody, and who were discharged between April 1991 and September 1993, in two areas served by Fukuoka Prefectural Yamato Health Center (n = 163) and Tagawa Health Center (n = 180) were followed up until November 1994.


RESULTS
The readmission rates within 6 months of discharge in Yamato Health Center and Tagawa Health Center were 17% and 22%, and within 1 year were 30% and 31% respectively. From Cox's proportional hazards model, alcohol/drug abuse, many of previous admission, long length of recent hospitalization, payment of medical care cost from public assistance, complication of physical disorders, living without a person responsible for custody after discharge, no request of health center's service by the hospital and discharge from a large-scale mental hospital were significantly related to increased risk of readmission. Not a few patients could not be followed up completely because of early drop-out of treatment. The drop-out rates within 1 month of discharge in Yamato Health Center and Tagawa Health Center were 10% and 26%, and within 1 year were 15% and 27% respectively.


CONCLUSIONS
The rates of readmission and drop-out of treatment among discharged psychiatric patients were considerably high. This study clarified that rapid establishment of a mental health system supporting the mentally disabled in a community is an urgent need in Japan.
