Brief summary (registry, in English)
The goal of this observational study is to describe the impacts of COVID-19 on primary care chronic condition management in Canada within various patient populations. This will be done by analyzing primary care electronic medial record (EMR) data from the Canadian Primary Care Sentinel Surveillance Network (CPCSSN) database, including data on primary care encounters, as well as various markers for chronic conditions. The research questions to be investigated are: 1a) What are the changes to the management of chronic conditions in primary care since the onset of the COVID-19 pandemic? 1b) How do these changes differ by age, health status, and socioeconomic status?
