Notes:
  • Many CCDSS measures, such as chronic disease incidence, were influenced by the COVID-19 pandemic. Changes in such measures may be driven by multiple factors, including (but not limited to) differences in healthcare seeking behaviour, the availability and use of healthcare services, as well as true changes in health status. As such, CCDSS measures should be used cautiously when making inferences about population health during the COVID-19 pandemic. Guidance for data users on examining the impacts of the COVID-19 pandemic on CCDSS measures can be accessed below.
  • Data suppression: Estimates are not reported when the counts are less than 10 or the coefficient of variation is greater than 33.3%.
  • Due to periodic updates of the historical surveillance data, estimates for a particular disease and year may change over time, and may not be comparable to previous editions.
  • Estimates are age-standardized to the 2011 Canadian population using unrounded counts and five-year age groups. Age-standardized estimates are useful for comparing data across years or between different geographical areas, but they do not reflect the actual impact of the disease.
  • The modernization of the Quebec billing system for fee-for-service medical services by the Régie de l'assurance maladie du Québec (RAMQ) in 2016 has resulted in a decrease in the entry of diagnostic codes in the fee-for-service medical services file. Data for 2016–2017 and subsequent years should therefore be interpreted with caution, as a slight underestimation is suspected.
  • The introduction of the Northwest Territories Electronic Medical Record (EMR) in 2016 resulted in more complete and consistent data. Data for 2016–2017 may be slightly underestimated compared to previous years due to the system transition. 
  • Nova Scotia data among individuals aged 1–19 are excluded.
  • Northwest Territories physician claim data were incomplete for 2021–2022 and should therefore be interpreted with caution, as a slight underestimation is suspected.
