[Pilot data from the Spirale project -- follow-up of occupational respiratory exposures]

Abstract

Introduction: The medical follow-up of individuals who have had occupational exposures to potential respiratory hazards is little known and under-utilised. The Spirale program aims to deliver this intervention effectively to all potential beneficiaries.

Methods: Spirale was introduced in two stages; i) identification of occupational exposures to asbestos or wood dust through a postal questionnaire; ii) for those initially identified, confirmation of exposure through attendance at a health centre for examination and further medical follow-up as necessary.

Results: In 2007, Spirale contacted 50,662 men born between 1942 and 1943, living in 13 departments in France. The initial response rate was 24%, rising to 50% after reminders. Seventy-two percent of people were identified as possibly having been exposed; 50% to asbestos, 3% to wood dust and 19% reporting a mixed exposure. Among the 8641 people located, 3843 (44.5%) benefited from an evaluation of their exposure. In total, 73.4% of people had their exposure to asbestos confirmed and in 1751 (64.2%) this was at a level to justify follow-up.

Conclusion: TheSpirale program largely achieved its objective of location and initiation of medical monitoring of people who have been exposed through their work to respiratory carcinogens. It should now be implemented throughout the country.
