The diagnostic usefulness of AUDIT and AUDIT-C for detecting hazardous drinkers in the elderly.
We compare the diagnostic usefulness of the Alcohol Use Disorders Identification Test (AUDIT) and the AUDIT alcohol consumption questions (AUDIT-C) for detecting hazardous drinkers between the populations over and less than 65 years in primary care settings. To assess weekly alcohol intake an interview on quantity-frequency was administered to 602 patients. Hazardous drinking was defined as a level of consumption of 280 g of alcohol per week for men and 168 g for women. The participants received AUDIT, AUDIT-C and CAGE questionnaires. Gamma-glutamyltransferase (GGT), mean corpuscular volume (MCV), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) values were also determined. Average weekly alcohol intake among the population aged 65 and older was 83 g, and 10% were hazardous drinkers. In this age group, the sensitivities of AUDIT and AUDIT-C for detecting this type of drinkers were 67% and 100%, whereas specificities were 95% and 81% respectively. In the younger patient group, the sensitivities were 84% and 100% and the specificities 95% and 79% respectively. In conclusion, both AUDIT and AUDIT-C perform well at detecting hazardous drinkers in the group older than 65 years and that their sensitivities and specificities are comparable to those in younger ages.
