Patients Admitted to Emergency Services for Drunkenness: Moderate Alcohol Users or Harmful Drinkers?

OBJECTIVE: Most of the patients admitted to hospital emergency services are drunk. Some of them may need specific treatment after acute intoxication remits. At present, treatment for alcoholism is offered to less than 5% of these patients. The authors evaluated the biological markers carbohydrate-deficient transferrin (CDT) and -glutamyltransferase (GGT) in patients admitted for acute alcohol intoxication (per DSM-IV criteria) supported by blood alcohol assay. These tests distinguished between otherwise moderate alcohol users who were acutely intoxicated and harmful drinkers or alcohol-dependent patients. METHOD: The authors conducted an exhaustive survey 24 hours a day during 2 nonconsecutive months. The study involved 166 patients (124 men and 42 women) who were admitted for acute alcohol intoxication as a principal or additional diagnosis. Their blood was analyzed for alcohol, GGT, and CDT levels. The CAGE questionnaire was administered, and social and demographic data were collected. RESULTS: About 80% of the population studied displayed elevated GGT or CDT levels (65.7% had CDT levels >60 mg/liter; 41.6% had GGT levels >65 IU/liter). Less than 10% of the patients with acute alcohol intoxication revealed results in the normal range for both markers and a negative finding on the CAGE questionnaire. CONCLUSIONS: Patients admitted to emergency services with high blood alcohol levels should not be assumed to be moderate drinkers. Any drunkenness should be interpreted as a sign of likely harmful alcohol consumption or alcohol dependency requiring clinical and biological tests, including GGT and CDT assays. Specific treatment for alcoholism should be systematically offered to these patients.
