The influencing factors of the relapse in alcohol-induced psychiatric and behavioral disorders

Abstract

Objective To explore the factors of relapse in alcohol-induced psychiatric and behavioral disorders. Methods 103 male inpatients met with the diagnostic criteria of alcohol-induced psychiatric and behavioral disorders according to ICD-10 were enrolled. All patients were hospitalized from Wuxi Mental Center from January 2013 to August 2015. As baseline, information was obtained within all patients, and relapse was evaluated one year after discharge.The Kaplan-Meier method was used to statistically analyze the alcohol relapse time of patients with different length of hospitalization. Cox regression was used to explore the risk factors for alcohol relapse, including age, education level, marital status, family history, smoking, fixed income, number of hospitalizations, duration of alcohol intake, average daily alcohol intake, time of psychosis, psychiatric symptoms, length of hospitalization, physical condition and mental condition. Results (1)The analysis (log rank) showed that the length of hospitalization had no significant statistical differences with relapse(χ2=0.069, P=0.966). (2) The number of hospitalizations (RR=1.074, 95%CI=1.002-1.151, P=0.042) and average daily alcohol intake(RR=1.035, 95%CI=1.012-1.059, P=0.003) were the risk factors for relapse. Conclusion The number of hospitalizations and average daily alcohol intake are risk factors for relapse within a year in male inpatients with alcohol-induced psychiatric and behavioral disorders. Prolonged hospital stay has no help to reduce relapse in those people. Key words: Alcohol-induced psychiatric and behavioral disorders; Relapse; Influencing factors
