Our guide to key COVID-19 evidence sources

 

To support decision-makers as they respond to unprecedented challenges related to the COVID-19 pandemic, teams from the McMaster Health Forum and Ottawa Hospital Research Institute – as part of their contribution to RISE – and the Africa Centre for Evidence have created and regularly update this guide to key evidence sources.

COVID-END strongly encourages those supporting decision-makers to:

  1. start your response to any evidence request by reviewing this guide to make the most of what little time you or your staff have to find evidence to inform a particular decision
  2. prioritize evidence syntheses, technology assessments and guidelines that have already been prepared using a robust process (as identified in the guide), have been rated as high quality by independent assessors (on some of the websites identified in the guide), or have been rated by an experienced team with which you work
  3. provide a ‘date stamp’ for any documents you cite (using the exact date of last search for evidence or, if that is not available, the date the document was finalized) given the fast-moving nature of the evidence related to COVID-19

For additional tips and tools to support decision-makers, see here.
