This project will launch a new system for occupational health surveillance through the linkage of existing administrative databases. The Occupational Disease Surveillance System (ODSS) will follow Ontario workers to identify risks of cancer, other chronic diseases and other health conditions. ODSS will provide timely information about existing and emerging work-related health risks through the linkage of existing health data sources.
Although Canada captures very good information about medical diagnoses in administrative health records, there is no way to determine where these patients worked or whether their health condition might be related to a workplace exposure. ODSS aims to overcome this challenge, which has limited our ability to identify and monitor work-related health risks, by using data linkage methods to identify jobs and work-related factors that can pose health risks to Ontario workers.
Expanding on a 2014 pilot project linking Workplace Safety and Insurance Board (WSIB) claims to Ontario Cancer Registry records, this project includes additional follow-up and additionally links to hospital, ambulatory care and medical billing records to identify work-related risks for health outcomes in addition to cancer.
When workers make claims to the WSIB for time lost due to injury or disease, their claims contain information about their occupations and industries. These claims can be linked to health records to compare risks across different occupations and industries. This approach can be useful for identifying high-risk jobs or workplace hazards that can be targeted with risk reduction efforts.
In addition to establishing a novel approach for occupational disease research, this project aims to translate ODSS-generated information into evidence-based prevention strategies to reduce workplace hazards through project engagement with occupational health and safety partners.
ODSS will be used to identify existing and emerging occupational risks for disease. This system could allow researchers to identify previously unknown work-related risks including previously unknown industrial chemicals. ODSS will enable rapid assessment of existing and emerging risks associated with various jobs in Ontario, and will highlight at-risk groups that should be targeted with risk-reduction strategies.
Progress (updated February 2018):
ODSS was launched in 2017, and captures information for more than 2 million Ontario workers. ODSS is currently being used to generate data on occupational risks for cancer and other health outcomes including asthma and contact dermatitis.
This project is funded by the Public Health Agency of Canada’s Enhanced Surveillance for Chronic Disease Program and the Ministry of Labour.
