In Quebec, the monitoring of the population’s health, including workers’ health, is governed by the Public Health Act. This law provides for the implementation of surveillance plans that define the parameters of the factors to be monitored. The Institut national de santé publique du Québec plays a key role in implementing these surveillance plans. It works in close collaboration with other relevant organizations, primarily the Ministry of Health and Social Services and the Regional Public Health Directorates. In the field of occupational health, the content of regional and national surveillance plans is divided into two sections: general and specific surveillance. General surveillance addresses broad topics such as mortality, morbidity, non-fatal injuries, and occupational exposures. Specific surveillance targets certain occupational health issues more precisely. These include, in particular, musculoskeletal disorders, respiratory diseases, poisonings, infectious diseases, cancers, hearing loss, adverse pregnancy outcomes, heatstroke, and stress. There are multiple sources of information required for surveillance, including, among others, data on compensated work-related injuries, surveys on workers’ exposure and health status, and government social and health records. Mechanisms for disseminating information to the public, workplaces, stakeholders, and decision-makers are also planned. (R.A.)
