The study is a randomized clinical trial, and aims to recruit 60 X 2 patients. Patients admitted to Stavanger University Hospital with an alcohol contributed condition, and who has been given a brief alcohol intervention may be recruited. Candidates for secondary healthcare related to alcohol misuse will be excluded. The interdisciplinary "booster" session will be given two weeks after discharge, and will be given in the facility of the primary care physician, facilitated by both the physician and an liaison alcohol nurse from Stavanger University Hospital. The intervention is based on motivational interview technique. The primary outcome will be assessed using the Alcohol Use Disorder Identification Test-C, six months after discharge. The outcome assessor will be blinded for the intervention. All outcomes will be collected by telephone interview.
