Nov. 4, 2025
The Nov. 4 community call featured the winners of the Best Community Contribution Honors from the 2025 Global Symposium. Four lead authors presented the work that earned top recognition from their peers across the OHDSI community.
Methods Research: Lu Li (University of Pennsylvania): LATTE: A One-shot Lossless Algorithm for Federated Target Trial Emulation with Application to Alzheimer’s Disease and Related Dementia Drug Repurposing Using Decentralized Data
Community: Clair Blacketer (Johnson & Johnson): Building the OHDSI Evidence Network – A Global, Open, Federated Collaboration
Data Standards: Jared Houghtaling (Tufts University): OMOP Waveform Extension: A Schema for Integrating Physiological Signals and Derived Features into the OMOP CDM
Clinical Applications: Hsin Yi “Cindy” Chen (Columbia University): Heterogeneity of Treatment Effects Across Nine Glucose-Lowering Drug Classes in Type 2 Diabetes: Extension of the LEGEND-T2DM Network Study
Open-Source Development honoree Adil Ahmed will present his work the following week during the software demo session.

Pole, and Clair Sullivan on the recent publication of Streamlining electronic medical record data extraction and validation in digital hospitals: A systematic review to identify optimal approaches and methods in Learning Health Systems.
• Congratulations to the team of Gucheol Jung, JaeHyeok Lee, Sung-Min Gho, YoungMi Han, ByungKwan Choi, Jae Wook Cho, Jiyoung Kim, and Gha-hyun Lee on the recent publication of Predicting oxcarbazepine-induced hyponatremia in adult epilepsy patients: A multicenter machine learning analysis using real-world CDM data in Seizure: European Journal of Epilepsy.
• Congratulations to the team of Nadav Rappoport, Guy Livne, Naama Perry Cohen, Nir Makover, Hadas Eshel-Geva, Hadar Kapach, Tomer Hadad, Yarin Alon, Robyn Rubin, Segev Chai, Shirell da Villa, and Ohad Hochman on the recent publication of Kineret: Israel’s Largest Hospital Network Transformed into the OMOP common data model for collaborative research in PLOS One.
• 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.
• The latest “On The 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.
• 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.
• 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.
Job Openings
• Erasmus MC recently posted job openings for both a Health Data Scientist and a PhD student in medical informatics. More details and an application link are available on the respective pages. The closing date for both positions is Nov. 17.
Save The Dates
• The first-ever 2025 OHDSI Africa Symposium will be held Nov. 10-12 in Kampala, Uganda, and registration is open. A tentative agenda has been posted on the event homepage.
• The 2025 OHDSI Asia-Pacific Symposium will be held Dec. 6-7 in Shanghai, China. Registration is open, and agenda details will be shared when available.
