Abstract The purpose of the present study was to identify the associated factors of rehospitalization in schizophrenic patients. A case-control study was conducted. The cases consisted of rehospitalized patients (n = 67) and controls selected from the outpatients who were matched by age, gender, and the period after the last discharge (n = 62). In the multiple logistic regression analysis, no clinic visits in the second month prior to entry, the number of clinic visits in the previous month, and junior high school graduation as education level were significantly (P < 0.01) associated with rehospitalization after controlling their present function as assessed by the Global Assessment of Functioning. Close monitoring of clinic visits and outreach service appear to be important in preventing rehospitalization of schizophrenic patients. These identified modifiable factors suggest further needs for development and implementation of integrated mental health services in the community.
