OHDSI UPDATES
Registration is open for the 2026 OHDSI Canada Symposium, held Nov. 17-18 in Toronto. This two-day event will bring together researchers, clinicians and data scientists, trainees along with public sector and industry partners from across Canada and beyond to explore the growing use of the OMOP Common Data Model and OHDSI in observational health research. The event will feature a workshop day on Nov. 17 and a main conference day on Nov. 18.
• Jiwon Um , a PhD student at Yonsei University in Korea, introduced a brief survey focusing on OHDSI in the Era of Medical AI. Medical AI is reshaping how observational research evidence is generated and used. The OHDSI community has spent more than a decade building infrastructure — OMOP CDM, standardized vocabularies, federated networks, open-source methodology — that may have a distinctive role in this transition. This survey asks how you, as a member of the community, see that role and the tensions surrounding it.
• A new call for papers is open for a Journal of Biomedical Informatics special issue focusing on agentic AI for generating trustworthy Real-World Evidence (RWE). The issue seeks contributions on multi-agent collaboration and coordinated autonomy across the RWE lifecycle—such as data harmonization and causal analysis—while excluding single-task AI agents. Submissions are accepted from June 15 through November 15, 2026, with publication slated for September 2027.
• The FALCON (Federated Alliance for Large-scale Cancer Observational Network) Research Network is dedicated to advancing real-world oncology evidence through federated health analyses. The network is hosting its 2026 Symposium and Bladder Cancer Studyathon from Sep. 28-Oct. 1 at Dunden in Antwerp, Belgium. This intensive four-day event kicks off with a general symposium followed by a three-day collaborative working session for researchers, clinicians, and data scientists to generate high-quality clinical evidence on the OMOP CDM.
OHDSI SOCIAL SHOWCASE
Research from the 2026 Europe Symposium Collaborator Showcase is being shared daily on OHDSI’s LinkedIn, X, Instagram and Bluesky social channels as part of the #OHDSISocialShowcase. Below are posters (with study leads) that are featured this week:
