This easy to use patient questionnaire is a screening test for problem drinking and potential alcohol problems. The CAGE questions should not be preceded by any questions about alcohol intake - ie its sensitivity is dramatically enhanced by an open-ended introduction.
A total score of 2 or greater is considered clinically significant (sensitivity of 93% and a specificity of 76% for the identification of problem drinking); compared with GGT liver function test which detected only a third of patients having more than 16 "drinks" per day. The Alcohol Use Disorders Identification Test (AUDIT) is a longer screening tool recommended by the WHO.
