OHDSI UPDATES
The latest edition of the OHDSI newsletter is now available. This edition includes materials from the 2025 Global Symposium (videos, slides, posters), the 2025 edition of the Our Journey booklet, a collaborator spotlight Q&A with Andrew Kanter, recent community updates, publications and presentations from October, and plenty more.
• Congratulations to Michael Matheny (VA, Vanderbilt) on his recent election as a new member of the National Academy of Medicine (NAM).
• Congratulations to Early-Stage Researchers Workgroup lead and recent Columbia PhD graduate Harry Reyes Nieva on being named a 2025 STAT Wunderkind, an award given to the top 30 early career scientists in North America.
• 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.
• There is a new tutorials homepage on OHDSI.org that hosts all tutorials from past Global/US Symposia, as well as tutorials from the SOS Challenge. Future tutorials will also be added here.
• 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.
