Effectiveness of an Intervention in Patients With Excessive Alcohol Consumption

* Main objective: to verify the effectiveness of a brief intervention, based on the motivational interview (MI), in patients with excessive alcohol consumption assisted in Primary Care (PC). * Design: a multicenter, randomized, cluster-controlled clinical trial with two parallel arms. PC professionals will be randomized to one of the two study groups: 1) Experimental Group (EG): MI-based approach; 2) Control group (CG): usual care. At least 50 family doctors, residents and nurses will participate, recruiting PC patients (n = 394). GE intervention: Training program to acquire specific skills on approaching risky alcohol consumption. It will consist of a workshop, with two video recordings of consultations with simulated standardized patients, before and after it, with each participant receiving formative feedback at the end. -Intervention GC: medical advice that is usually performed in these patients. To measure the knowledge and attitude of professionals in dealing with patients with alcohol consumption, they will fill out a validated questionnaire. In addition, expert evaluators, after viewing the video recordings, will fill out a check-list to check the attitude of each professional, using the EVEM Scale. -Study population: patients ≥14 years of age with risky consumption, detected by the professional in health centers in the province of Córdoba (Spain). Sample size: Assuming a loss rate of 5%, and the "cluster design effect", the number of subjects to be recruited is estimated at 394 (197 / group). Intervention control mechanism: each participant will be audio-recorded with a real patient in a randomly chosen visit, evaluating her skills with the EVEM scale. The follow-up period for each patient will be 12 months, with 4 visits (initial, per month, 3 months, and 6 months) and 4 interleaved telephone contacts. The main outcome variable will be the level of self-reported alcohol consumption and the AUDIT questionnaire score. -Statistical analysis by intention to tr
