Weekly OHDSI Digest- September 4, 2023


Please join our Sept. 5 (11 am ET) community call for a look at the DARWIN EU® Progress and Roadmap. DARWIN EU® is an initiative that works to deliver real-world evidence from across Europe on diseases, populations and the uses and performance of medicines. As the program enters Phase III, members of the leadership team will provide an update on both its progress and goals. This presentation will be led by:

• Peter Rijnbeek (Professor of Medical Informatics and Chair, Department of Medical Informatics, Erasmus MC)

• Katia Verhamme (Associate Professor of Use and Analysis of Observational Data, Department of Medical Informatics, Erasmus MC)

• Ed Burn (Senior Researcher in Epidemiology and Health Economics, University of Oxford)

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.
