Brief interventions are effective in reducing alcohol consumption in opiate-dependent methadone-maintained patients: results from an implementation study.

INTRODUCTION AND AIMS: An implementation study to test the feasibility and effectiveness of brief interventions (BIs) to reduce hazardous and harmful alcohol consumption in opiate-dependent methadone-maintained patients. DESIGN AND METHODS: Before and after intervention comparison of Alcohol Use Disorders Identification Test (AUDIT-C) scores from baseline to 3month follow up. Seven hundred and ten (82%) of the 863 eligible methadone-maintained patients within three urban addiction treatment clinics were screened. A World Health Organization protocol for a clinician-delivered single BI to reduce alcohol consumption was delivered. The full AUDIT questionnaire was used at baseline (T1) to measure alcohol consumption and related harms; and in part as a screening tool to exclude those who may be alcohol-dependent. AUDIT-C was used at 3month follow up (T2) to assess any changes in alcohol consumption. RESULTS. One hundred and sixty (23% of overall sample screened) 'AUDIT-positive' cases were identified at baseline screening with a mean total full AUDIT score of 13.5 (SD 6.7). There was a statistically significant reduction in AUDIT-C scores from T1 ( , SD=2.35) to T2 (, SD=2.66) for the BI group (z=-3.98, P<0.01). There was a statistically significant decrease in the proportion of men who were AUDIT-positive from T1 to T2 (χ(2) =8.25, P<0.003). DISCUSSION AND
CONCLUSIONS: It is feasible for a range of clinicians to screen for problem alcohol use and deliver BI within community methadone clinics. Opiate-dependent patients significantly reduced their alcohol consumption as a result of receiving a BI.
