OHDSI UPDATES
The second-annual OHDSI Summer School in New York City was held in late June, and an international cohort of learners traveled the path from learning about observational research to performing their own network studies within one week.
• Oxford University also welcomed a cohort of learners to discovery the possibilities using real-world data, OMOP, and the OHDSI way of generating reliable and robust real-world evidence. Thank you to the faculty at both Columbia and Oxford for welcoming new collaborators to our community.
• Please save the date for the 2026 OHDSI APAC Symposium, which will take place Nov. 13-15 at Yonsei University in Seoul, South Korea. This will be a 3-day event, kicking off with the main conference and then including tutorials and a datathon during the weekend. Registration has not opened yet, but please check the event homepage for details on the agenda and registration.
• 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.
• Take your OMOP CDM from implementation to impact with The OMOP Practitioner, an intensive three-day expert training hosted Sept. 7-9 by Erasmus MC in Rotterdam. This hands-on program moves beyond the basics, offering a maximum of 30 participants deep-dive experience with the Data Quality Dashboard, ATLAS, and real-world study execution.
OHDSI SOCIAL SHOWCASE
Research from the 2026 Europe Symposium 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 — DARWIN EU® - Incidence rates of venous thromboembolic events in individuals with selected cancers (Anton Barchuk)
Tuesday — DARWIN EU® - Drug Utilisation Study of terbinafine-containing products (Ellen Gerritsen)
Wednesday — Large-Scale Extraction and Standardization of Primary Care Vaccination Data to the OMOP Common Data Model in Wallonia, Belgium (M. Borshchivska)
Thursday — Cohort profile: SWEdish register-based Evidence for Pharmacovigilance (SWEEP) (Judith S Brand)
Friday — An Iterative Annotation Pipeline for Building Clinical Datasets and Training Information Extraction Models: The PREPARE Project (Erik Calcina)
UPCOMING OHDSI EVENTS
The first OHDSI Latin America Symposium will be held July 30-31 in Salvador, Brazil. The event will include multiple workshops, including sessions focused on Introduction to OMOP, Cohort building, ETL for OMOP, and Scientific collaboration: opportunities for network studies in Latin America.
• The UK Symposium will be held September 18 at the University of Nottingham, preceded by an OMOP Training Day on September 17. The call for abstracts has opened, and the deadline is set for May 1.
• Registration and the call for participation are now open for the 2026 OHDSI Global Symposium, held Oct. 20–22 at the Hyatt Regency in New Brunswick, N.J. You can also read more about our 12 new tutorial offerings which will take place during Day 1 of the event. The deadline to submit your brief reports for the Collaborator Showcase is June 5 at 8 pm ET.
