CanadiEM is excited to formally partner with the Canadian COVID-19 Emergency Department Rapid Response Network (CCEDRRN, pronounced “sedrin”), the third largest COVID-19 observational registry in the world according to the World Health Organization (WHO). Stay tuned for infographics, blog posts and other materials to disseminate high-quality Canadian research results on the COVID-19 Pandemic, and reduce the knowledge translation gap for frontline healthcare workers!

The Canadian COVID-19 Emergency Department Rapid Response Network (CCEDRRN) is a new, multi-centre COVID-19 observational registry, one of the largest in the world. This registry was developed in response to Emergency Physicians’ need for high quality evidence to make diagnostic and treatment decisions for patients with suspected or confirmed COVID-19. Since March 2020, the CCEDRRN has enrolled over 85,000 consecutive patients visiting 50 Emergency Departments across eight provinces in Canada. Among this geographically distributed sample, >15,000 patients have been diagnosed with COVID-19.

Through the retrospective chart review and phone follow-up of enrolled patients, this methodology study​1​ has the following four objectives:

  1. Describe COVID-19’s natural history
  2. Create clinical decision rules which predict COVID-19 test positivity and futility of intubation
  3. Evaluate diagnostic tests such as screening asymptomatic admissions
  4. Determine the real-world effectiveness of treatments and/or vaccines

Ultimately, this large, Canadian collaborative network serves: to produce robust scientific evidence to inform the pandemic response, and as an archetype for collaborative research during future public health emergencies. Using an Open Science Framework, the network invites the use of their data and encourages external investigators to contact the network directly.
