Brief Integrated Outpatient Dual-diagnosis Treatment Reduces Psychiatric Hospitalizations

A retrospective pilot study was conducted to determine whether a relatively brief integrated outpatient treatment for patients with dual disorders reduced inpatient hospital service utilization. Outpatients (n=44) with substance dependence and either comorbid schizophrenia, major depressive disorder, or bipolar disorder were studied. A multidisciplinary team provided relatively brief (up to 24 weeks), integrated, dual-diagnosis outpatient treatment. A significant 60% reduction in the number of psychiatric hospitalization days was found for the year after treatment as compared to the year before. Patients with schizophrenia showed the greatest reduction (74%) in hospitalization days. Thus, even brief integrated outpatient dual-diagnosis treatment can reduce inpatient psychiatric hospitalizations. (Am J Addict 2003;12:306-313)
