It links job information and health records to detect and monitor occupational disease.
A worker who is compensated for a workplace-related illness or injury that resulted in missing work is captured in the provincial compensation board’s time-loss database. This database captures job information such as a worker’s occupation and industry of work associated with the claim. The ODSS was created by linking this source of job information to administrative health databases.
To identify disease cases, the ODSS cohort of 2.4 million workers was linked to tumour registry data, hospital records, ambulatory care records, and physician billing records. By combining occupation and industry from time-loss compensation claims data with disease information from administrative health databases, the ODSS provides an efficient approach to study work-related diseases.
