Title: Impact of Interventions to Prevent Asbestos-Related Respiratory Disease
What would happen if we reduced asbestos exposure in a cohort of construction trades workers enrolled in an exposure surveillance registry? Intervening sooner to reduce asbestos exposure could substantially lower the cumulative risk of asbestos-related respiratory disease among workers in the Ontario Asbestos Workers Registry cohort study. In our study of over 26,000 workers, stopping asbestos inhalation after 100 reported hours of work with asbestos-containing materials could have prevented 76 cases of asbestosis and reduced the risk of lung cancer by 15%. Causal modelling with g-methods allows epidemiologists to generate evidence that better informs the kinds of decisions that policy-makers actually make: What are the benefits of reducing exposure to specific levels, and how much will it cost to get there?
