Weekly OHDSI Digest – January 27, 2025

WEEKLY COMMUNITY CALL MEETING

Guideline-driven evidence generation is an early community focus in 2025, and collaborators have started to share opportunities in this forum post. We heard about potential focuses like obesity and pneumonia in our first session on clinical guideline opportunities; and we invite you to join our Jan. 28 community call (11 am ET) to hear about others, including oncology, anesthesia, psychiatry and more.

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.
