The investigators will conduct a population-based cohort study using linked provincial health administrative data (based at ICES) and clinical sleep data from the Sunnybrook Health Sciences Centre Sleep Laboratory.
ICES holds an individual-level, longitudinal, coded, linkable and secure and privacy protected health databases on most publicly funded health services for the Ontario population eligible for universal health coverage since 1991 (http://www.ices.on.ca/Data-and-Privacy/ICES-data). The records in ICES data include information on physician claims submitted to the Ontario Health Insurance Plan, discharge summaries of emergency department visits and hospital stays and for those 65 years and older medical drug claims to the Ontario Drug Benefit Program. These databases will be linked using unique encoded identifiers and analysed at ICES.
In Ontario, details on physician and hospital services are captured in several health administrative databases; of these databases, the investigators plan to use the following datasets among others: (i) the Ontario Health Insurance Plan (OHIP) physician services database; (ii) the Canadian Institute for Health Information Discharge Abstract Database; (iii) the Ontario Registered Persons Database; (iv) Ontario Registrar General - Death (Vital Stats); and (v) the Ontario Stroke Registry.
ICES is a prescribed entity under section 45 of Ontario's Personal Health Information Protection Act (PHIPA). Section 45 is the provision that enables analysis and compilation of statistical information related to the management, evaluation and monitoring of, allocation of resources to, and planning for the health system. Section 45 authorizes health information custodians to disclose personal health information to a prescribed entity, like ICES, without consent for such purposes.
