Effect of adding individualized occupational therapy to standard care on rehospitalization of patients with schizophrenia: A 2-year prospective cohort study

AIM We examined the effect of individualized occupational therapy (IOT) compared to the usual group occupational therapy (GOT) on the rehospitalization of patients with schizophrenia. METHODS A prospective cohort study included patients with schizophrenia who were discharged within 1 year from a psychiatric hospital. Time to rehospitalization by treatment group (GOT + IOT or GOT-alone) was evaluated with Kaplan-Meier survival analysis. The impact of demographics and clinical factors associated with rehospitalization was investigated using Cox proportional hazards models. RESULTS Of the 111 patients who met the criteria, 54 were in the GOT + IOT group and 57 in the GOT-alone group. Over the 2 years from discharge, the overall rehospitalization rate was 51.376% (56 patients); the GOT + IOT group demonstrated a significantly lower rehospitalization rate with 16 patients rehospitalized compared to 40 patients from the GOT-alone group. Time to rehospitalization was significantly longer for the GOT + IOT group compared to those in the GOT-alone group (P
