Weekly OHDSI Digest – August 7, 2023


Please join us Tuesday, August 7 (11 am ET) for our next OHDSI community call, which will be our annual “Newcomer Introductions” session. OHDSI is all about the collaboration within our community, and we are always looking to make new connections. If you are new to the community, or even if you’ve been around for a while and feel ready to get more involved, we would love to hear from you!

We will give you the floor to introduce yourself, share a bit about your background, say why you have joined OHDSI and perhaps how OHDSI can help you. To facilitate the call, we ask interested people to register here to ensure you are part of the session. You can also simply join the call and raise your hand to join.

Everybody is invited. Calendar invites went out last week. If you did not receive one, please use this link to join the meeting. All recordings from these weekly calls are available within our Teams environment and will be posted on both our YouTube page and our OHDSI.org Community Calls page.

• Titan Award nominations are now open. To recognize OHDSI collaborators (or collaborating institutions) for their contributions towards OHDSI’s mission, the OHDSI Titan Awards were introduced at the 2018 Symposium and have been handed out at the U.S./Global Symposium each year since. You can nominate a community member for a 2023 Titan Award now; the deadline is Sept. 15, 2023.

• The OHDSI Global Symposium will host our first ever ‘OHDSI Got Talent’ event. As with the popular television series, we will have a series of contestants perform 4-6 minute routines to showcase their talent, and a panel of judges will share their thoughts on what they have seen. The OHDSI community will vote for their favorite and we will crown a winner! Do you sing or play a musical instrument? Do you dance? Can you do magic or comedy? Do you have some other unique skill that you can demonstrate in 6 minutes or less? We want to see it! If you are interested in participating, please fill out this form. The deadline to submit this form is 8pm ET on Friday, September 22; you will be notified of your acceptance by Friday, September 29.

Dmitry Dymshyts contributed the threshold fixes. Please visit the Changelog for more detail on the changes.

• Joel Swerdel announced the release of PheValuator 2.2.9. It allows for using a cohort to specifically designate cases for determining true and false negatives and positives.
