Weekly OHDSI Digest-December 14, 2020

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.

Tuesday, December 15 Community Call:
We have ONE more Tuesday call left in 2020, and we’re planning to bring out the holiday vibes within our global community. You will not want to miss this one! We have some fun surprises planned, but we also have a couple requests for those who would like to partake in the fun:

  1. Show us how festive you can get! We’re talking holiday decorations and/or clothing … the more, the merrier!
  2. We would love to spend some time on a OHDSI-themed “holiday gift exchange.” Is there a gift that OHDSI, or an OHDSI collaborator, ‘gave’ to you in 2020? Wrap it up (or for lazier ones like me, find a good gift bag) and plan to unwrap and share this gift during the hour! Funny … serious … sentimental … it all works!

We won’t divulge any more, but let’s face it, 2020 was rough. We do hope you can join Tuesday (12 pm ET) so the OHDSI community can come together one last time and share some joy as we say goodbye (good riddance?) to 2020 and look ahead to better days! See you there!
