BACKGROUND This real-world study aimed to investigate the use of the Alcohol Use Disorders Identification Test (AUDIT) in men admitted to a psychiatric hospital. MATERIAL AND METHODS The AUDIT questionnaire (10 items) was consecutively administered for a period of 3 years to male patients admitted to a psychiatric hospital (n=636). Laboratory blood tests of biochemical parameters were measured as biomarkers of alcohol consumption. Data were evaluated using linear models with mixed effects in the case of continuous dependent variables and logistic regression models with mixed effects in the case of categorical dependent variables. RESULTS We found that 45.3% of the patients had a high risk of alcohol consumption or alcohol dependence and 54.7% had a low risk of alcohol consumption. The ICD-10 diagnoses of alcohol-related disorders (F1x), psychotic disorders (F2x), affective disorders (F3x), neurotic and psychosomatic disorders (F4x) were statistically significantly associated with total AUDIT score (P<0.001). There was a statistically significant association between the total AUDIT score and length of hospitalization (P=0.004) and the incidence of suicidal thoughts (P=0.003). Plasma concentrations of alanine aminotransferase (P=0.005), aspartate aminotransferase (P<0.001), gamma glutamyltransferase (P=0.001), total cholesterol (P=0.027) and mean corpuscular value of erythrocytes (P<0.001) were statistically significantly increased with a higher AUDIT score. CONCLUSIONS This real-world study showed that the AUDIT questionnaire evaluated the severity of disorders caused by alcohol and their impact on comorbid mental disorders. These results may be helpful in improving targeted interventions in this group of patients.
