The Inserm collective expert report (2003), the National Conference on Alcohol (2007), and the reports and action plans of the Interministerial Mission for the Fight Against Drugs and Drug Addiction had, in various ways, highlighted the importance of involving occupational physicians in the field of addiction and the value of fostering collaboration between occupational medicine and community practice. In this context, following several exploratory studies, INPES, the National Institute for Health and Safety (INRS), and the Western Île-de-France Society of Occupational Medicine (SMTOIF)—all strongly committed to supporting these professionals—decided to undertake a study on the opinions and practices of occupational physicians regarding the prevention of addictive behaviors: the role of addiction in occupational health priorities, documentation in medical records, knowledge and practices regarding brief interventions, opinions on screening tests, and involvement in individual prevention and collective initiatives.[article excerpt]
