This Week In OHDSI

Nov. 28, 2023

The Nov. 28 community call provided an update about the OHDSI Coordinating Center at the Columbia University Department of Biomedical Informatics, its role in guiding the community, and to learn about how the community can support OHDSI’s mission as we move into 2024. George Hripcsak, Professor of Biomedical Informatics at Columbia University, leads this session, which includes both a presentation and discussion at the end.
