As part of the preparation for the national study on the effectiveness of brief interventions in occupational health (EIST), a feasibility study was conducted in 2004 by the "Drink Less, Feel Better" (BMCM) program, in collaboration with 32 occupational physicians and their 38 assistants. It enabled the assessment of alcohol-related risk using the AUDIT questionnaire among 2,060 employees. This article describes the findings from the analysis of the questionnaires completed by employees and occupational health personnel who participated in the study. Of the 1,839 questionnaires analyzed, risky or problematic drinking affected 7.8% of employees [95% CI: 6.8–9.0], and alcohol dependence affected 1% [0.6–1.4]. Two-thirds of the at-risk drinkers identified by the AUDIT would not have been identified by a biological screening strategy. The questionnaire, its administration method, and the brief intervention were deemed acceptable by the physicians and assistants responsible for distributing the questionnaire and verifying that it was completed correctly. The results highlight the relative frequency of misuse without dependence. The authors conclude that the frequency of risky use justifies focusing an occupational health prevention strategy on this issue.
