Diagnosis and Management of Substance Use Disorders Among Inpatients With Schizophrenia

OBJECTIVE: The study examined the extent of clinical recognition of comorbid substance use disorders and the clinical management of these disorders among inpatients hospitalized for an acute exacerbation of schizophrenia. METHODS: Medical records of 42 inpatients who met research diagnostic criteria for both schizophrenia and a current substance use disorder were reviewed for information about admission evaluation, inpatient management, discharge diagnosis, and disposition. RESULTS: Alcohol use disorders were the most frequent co-occurring substance-related diagnoses, found for 86 percent of the dually diagnosed inpatients. Twenty-four patients (57 percent) did not receive a diagnosis of a substance-related disorder at admission, and 19 (45 percent) did not receive a substance-related diagnosis at discharge. Referral to inpatient or outpatient substance abuse treatment was documented for a minority of subjects. Conclusion: The results suggest that improvements are needed in the process of clinical care for inpatients with schizophrenia who have co-occurring substance-related disorders. They highlight a need for education of health care providers and continuous quality improvement in this area.
