Canadian COVID-19 Emergency Department Rapid Response Network

+200,000 patients enrolled

3rd largest COVID registry listed by the WHO


Canadian COVID-19 Emergency Department Rapid Response Network

The Canadian COVID-19 Emergency Department Rapid Response Network (CCEDRRN) is a national collaboration with Public Health partners to harmonize data collection related to COVID-19 in more than 51 Emergency Departments (EDs) across 8 provinces (BC, AB, SK, MB, ON, QC, NS, NB).

To date, CCEDRRN has captured data on over 200,000 patients across Canada, with ongoing weekly accrual of 2,000-2,500 COVID-19 tested patients. This allows us to conduct well-powered investigations on specific populations within Canada.
