Weekly OHDSI Digest-February 20, 2023


Please join our Feb. 21 community call (11 am ET) for our third update on Phenotype Phebruary, which is being led by Gowtham Rao and Azza Shoaibi. The phenotype discussions that were featured during Week 3 included Parkinson’s disease (Allan Wu) and myocardial infarction (Mirza Khan/Adam Atif). There is also an ongoing discussion on what makes cohort definitions reusable, which will be included in the update. To join or follow any of these discussions, please visit our Phenotype Phebruary homepage.

We will also have our third week of 2023 objectives & key results (OKRs) announcements from our OHDSI workgroups. On Tuesday, we will hear about the following teams: Early-Stage Researchers (Faaizah Arshad), Healthcare Systems Special Interest Group (Melanie Philofsky), THEMIS (Melanie Philofsky), Oncology (Asieh Golozar), Eye Care and Vision Science (Michelle Hribar), Latin America (Jose Posada), Psychiatry (Dmitry Dymshyts), and Health Equity (Jake Gillberg).

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 will be posted on both our main OHDSI Teams tenant and on our OHDSI.org Community Calls page.
