SY04-1 * PREDICTORS OF IN-PATIENT TREATMENT OUTCOMES FOR ALCOHOLISM: A REPORT FROM THE JAPAN COLLABORATIVE CLINICAL STUDY ON ALCOHOL DEPENDENCE (JCSA)

Introduction. In Japan, in-patient treatment hospitals for alcohol dependence (AD) are located throughout the country. However, comprehensive studies regarding predictors of treatment outcomes after discharge have not been conducted sufficiently. Therefore, we analyzed data obtained from the Japan Collaborative Clinical Study on Alcohol Dependence (JCSA) to examine this issue. Method. Fifty-four hospitals throughout Japan participated in the JCSA. In each hospital, surveys on the clinical characteristics and treatment of as many as 25 patients who were consecutively hospitalized within the fixed study period were conducted. The patients were followed up for 6 months after discharge, and the predictors of treatment outcome were assessed. Result. A total of 853 patients with AD (females, 16%) were enrolled. The rate of abstinence among the subjects was 39.7%. Male patients who lived together with someone, who were married, or who had completed the program, had higher rates of abstinence. The regression analysis indicated associations between abstinence after discharge and marital status, history of previous hospitalization, completion of the treatment program, and a depression episode after discharge. Conclusion. We identified predictors of inpatient outcomes after treatment for AD using a prospective study design. These findings could contribute to improving the quality of treatment for AD.
