The Canadian Primary Care Sentinel Surveillance Network (CPCSSN) is Canada’s first multi-disease surveillance system based on primary care electronic medical record (EMR) data.

The data comes from physicians participating in 10 practice based research networks across Canada, extracted from multiple EMR systems.  The data is extracted quarterly, mapped to a common database structure then cleaned and coded.   Case detection algorithms are run against the dataset to identify individuals with one or more of eight chronic conditions (diabetes, hypertension, osteoarthritis, depression, chronic obstructive lung disease, dementia, Parkinson’s disease and epilepsy).

The data within the CPCSSN database can be used to serve a number of different purposes and provide timely answers to relevant questions. For a downloadable copy of the CPCSSN case definitions click below.

For example, the data could be used to identify differences in disease rates, like osteoarthritis, in the populations of Alberta, Quebec and the Atlantic provinces to better understand the need for health resources in different regions.  There are many more possibilities – many of which were never possible before the creation of CPCSSN.

Letter of Intent for a Proposed Study with CPCSSN Data

For researchers who would like to include CPCSSN data as part of a research study, submitting a Letter of Intent (LOI) outlining their proposed research and data required is the first stage in the process. Details of the process of acquiring CPCSSN data for a research study, including proposal evaluation criteria and proposal submission & processing steps are available below.

Please note: We only release calculated (derived) data to researchers, with justification for the fields you are requesting.

Enter & Submit ”Letter of Intent”

After receiving your Letter of Intent, a member of the CPCSSN team will contact you and help with the review and approval process.
