The purpose of this study was to investigate if brief treatment for alcohol dependence in primary care with the 15-method was as effective as specialist addiction care. In addition, we sought to investigate trajectories for change of alcohol consumption.This study was a randomized controlled noninferiority trial, between-groups parallel design, with a noninferiority limit of 50 g of alcohol per week. A total of 288 adults fulfilling ICD-10 criteria for alcohol dependence were randomized to treatment in primary care or specialist outpatient care at a university addiction clinic. The primary outcome was change in weekly alcohol consumption at the 12-month follow-up. Secondary outcomes were heavy drinking days, severity of dependence, consequences of drinking, psychological health, quality of life, satisfaction with treatment, and biomarkers. Trajectories were investigated using change in World Health Organization drinking risk levels.The intention-to-treat analysis (n = 231) showed that the estimated weekly alcohol consumption in primary care was 18.2 g (95% CI [14.9, 51.3]) higher compared with specialist care (p = .28). Noninferiority was not demonstrated as the confidence interval exceeded the noninferiority limit. The secondary outcomes showed no differences between primary care and specialist care except that patients randomized to specialist care were more satisfied with treatment. The analyses of trajectories showed the main part of change in consumption occurred from baseline to the 6-month follow-up and was maintained to the 12-month follow-up.Although noninferiority could not be demonstrated, based on similar trajectories and sustained reduction of alcohol use, this study indicates brief treatment of alcohol dependence in primary care with the 15-method is a feasible and promising approach.
