WEEKLY COMMUNITY CALL MEETING
From global symposia across four continents to expanding workgroups, national nodes, and early-stage researcher engagement, 2025 has been a remarkable year for OHDSI. Our community published 150+ peer-reviewed studies, introduced new open-source tools, and contributed evidence that supported regulatory decision-making — and that’s just part of the story.
Join us Dec. 8 at 11am ET for a special community call as we look back at the wins, the challenges, and the lessons learned over the last 12 months.
Everybody is invited. If you do not have a calendar invite, 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.

OHDSI UPDATES
The OHDSI India Symposium (Dec. 2) and the OHDSI APAC Symposium (Dec. 6-7) were both held over the last week. Thank you to everybody who collaborated to lead both events.
• The 12th annual OHDSI Global Symposium will return to the Hyatt Regency Hotel in New Brunswick, N.J., Oct. 20-22, 2026. All pertinent information will be added to this page when available. Currently, the OHDSI steering group is seeking proposals for both plenaries and tutorials. The deadline for both is January 30, 2026; more details are available on the event homepage.
• The December edition of the OHDSI newsletter is now available. This includes information on five in-person OHDSI events across four continents that are taking place over the last two months of the year, as well as recent community updates, recent publications and presentations, and plenty more.
• Hua Xu is a well-known researcher in clinical natural language processing (NLP), and he leads the OHDSI NLP workgroup. He has developed novel algorithms for important clinical NLP tasks such as entity recognition and relation extraction, which have been top ranked in over a dozen of international biomedical NLP challenges. His lab has developed CLAMP, a comprehensive clinical NLP toolkit that has been successfully commercialized and used by hundreds of healthcare organizations. In the latest OHDSI Collaborator Spotlight, Hua reflects on his career journey, work being done at Yale, how NLP impacts the OHDSI mission of generating real-world evidence that impacts healthcare, and more.
• There is a new tutorials homepage on OHDSI.org that hosts all tutorials from past Global/US Symposia, including all six tutorials from the recent Global Symposium.
• The latest Our Journey annual report is now on the OHDSI homepage. This 134-page PDF provides an overview of the OHDSI community, including a look at its collaborators and collaborative activities, its research areas and tools, its work with standardized data and vocabularies, and nearly 900 publications that have come from the community.
• Registration is now open for the 2026 Summer School in Observational Health Data Science & Informatics, AI, and Real World Evidence, which will be held June 22-26 at the Columbia University Department of Biomedical Informatics. Now in its second-year, the Columbia OHDSI Summer School provides health professionals, researchers, and industry practitioners with an immersive, hands-on training to working with real-world health data and generating real-world evidence (RWE). Participants will explore the types of healthcare data captured during routine clinical care—such as electronic health records and administrative claims—and learn how to standardize these data using the OMOP Common Data Model to support collaborative, distributed research as part of a data network.
OHDSI Social Showcase
• Research from the 2025 Global Symposium Collaborator Showcase is being shared daily on OHDSI’s LinkedIn, Twitter/X, Instagram and Bluesky social channels as part of the #OHDSISocialShowcase. Below are posters (with study leads) that are featured this week:
