OHDSI UPDATES
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.
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 — Data quality framework for cohort discovery: Insights from the design of the global WAYFIND-R oncology real-world data research platform (Tom Stone)
Tuesday — Development of the HEARTwise ML framework to predict patient
