Weekly OHDSI Digest- January 11, 2021

OHDSI STATEMENT ON COVID-19 OHDSI is committed to doing what it can to support and inform the COVID-19 pandemic response, and will prioritize activities aligned to this effort. As we adjust to the current global situation, the OHDSI community will continue to have our regular Tuesday community calls, as well as our various working group calls. Understandably, some calls could be postponed or cancelled due to issues surrounding COVID-19, so we ask that you continuously check the OHDSI forums, weekly digest and social channels for updated information. OHDSI is a virtual community, so we are equipped to continue collaboration during this challenging time.
