Globally, an estimated 237 million men and 46 million women have alcohol-use disorders, with the highest prevalence in Europe and the Americas. The diagnosis of alcohol abuse or misuse is best made by taking a patient's history. Laboratory tests do not have a high sensitivity. Blood tests, such as liver function tests and mean corpuscular volume, are not particularly effective. Physical examination is helpful only after the consequences of alcoholism are apparent.
These are signs of chronic alcoholism:
Dupuytren contractures (also may be congenital)
Enlarged or shrunken liver
Many studies have demonstrated that brief interventions by physicians can improve excessive alcohol use in patients. These interventions are recommended by the World Health Organization and the Community Preventive Services Task Force. A systematic review concluded that brief (10-15 minute) multicontact interventions (eg, two 15-minute sessions with a primary care doctor 1 month apart, each followed 2 weeks later by a 5-minute telephone call with a nurse) helped reduce alcohol consumption.
