WEEKLY COMMUNITY CALL MEETING
The 2025 OHDSI Global Symposium is coming soon, and the Sept. 30 community call (11 am ET) will be our final session before the event. We will share final logistical updates for the symposium, and then we will welcome any of our 130+ collaborator showcase presenters to share why attendees should visit their poster or demo during our annual Mad Minutes session. If you are interested in promoting your work, please fill out this form.
If you haven’t registered for the Global Symposium yet, you can do so here.
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
Tiffany Callahan (Senior Machine Learning Research Scientist at SandboxAQ) will provide a talk (Oct 30, 11 am ET) on ‘Agentic Mixture-of-Workflows for Multi-Modal Chemical Search’ during the next edition of The Center for Advanced Healthcare Research Informatics (CAHRI) at Tufts Medicine speaker series. This will be held on Zoom; please reach out to Marty Alvarez ([email protected]) if you are interested in joining the session.
• 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.
• A scholarship honoring the late Jamie Weaver has been created at the University of Oxford, and applications are now being accepted. This 3-year PhD funded studentship will focus on ‘Improving the quality of real world evidence by measuring and minimising outcome misclassification using the OMOP common data model and large multinational health data,’ research that Weaver was leading during his time as a PhD trainee at Oxford. More information and application details are available here.
OHDSI Social Showcase
• Research from the 2025 Europe 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:
Monday — Implementing a Minimum Essential Definition of Cancer: Establishing standards and harmonising coding principles for a minimal cancer dataset in the OMOP common data model (Adil Ajmal)
Tuesday — OHDSI vocabulary updates with kotobuki (Sofia Bazakou)
