Patients will be recruited in various surgery units in 7 hospital in France. All patients attending a scheduled surgery will be screened during the visit with the anaesthesist by the Alcohol Use Disorders Identification Test (AUDIT). Patients aged 30-75 with an AUDIT between 7 and 12, corresponding to at risk or harmful use, will be proposed to enter a control study and randomized between a brief intervention by a trained nurse during the post-surgery hospitalisation and no intervention. Twelve months after the surgery, a research technician will interview by telephone patients and evaluate AUDIT and alcohol consumption of the last month.
