WEEKLY COMMUNITY CALL MEETING
Please join our weekly OHDSI community call on Tuesday, May 19 (11 am ET), as Columbia University Assistant Professor Matthew McDermott presents MEDS (Medical Event Data Standard). MEDS is an open-source ecosystem that acts as a universal adapter for medical research, offering massive potential to augment the OHDSI community by making our data network more accessible to the growing field of artificial intelligence. During the call, Matthew will discuss how this framework can enhance OHDSI global research and bridge the gap to advanced AI modeling.
Reminder: The deadline to submit your brief report for the 2026 Global Symposium is June 5 at 8 pm ET. Learn more and find the abstract submission form.
Everybody is invited. If you didn’t receive a call invite, please use this link to join. The call schedule and previous recordings can be found on the community calls page.

Bozkir, Nils Freyer, Patrick May, Yvonne Weber, Rainer Röhrig, Myriam Lipprandt on the recent publication of Flexible Data Integration for Genomics-Driven Decision Support in Rare Genetic Epilepsy in Volume 33 of Studies in Health Technology and Informatics: dHealth 2026.
OHDSI UPDATES
• There are 18 DAYS REMAINING before the deadline to submit your brief report(s) for the 2026 Global Symposium Collaborator Showcase. All information is available here, and you can submit your reports here. The deadline to submit your brief report(s) for the Collaborator Showcase is June 5 at 8 pm ET.
• Julio Oliveira is a physician, physicist, and entrepreneur dedicated to advancing the use of real-world data to improve research and decision-making in Latin America. He is a regional leader in the OHDSI community, where he supports the growth of the OMOP Common Data Model and collaborative observational research across LATAM. His broader mission is to strengthen data quality, interoperability, and research ecosystems that can generate meaningful evidence for patients, providers, researchers, and health systems. In the latest collaborator spotlight, Julio reflects on his path to OHDSI, its growth in Latin America, why now is the right time for the first LATAM Symposium, and more.
• The 2026 OHDSI Europe Symposium welcomed a record number of both participants and collaborator showcase submissions to Rotterdam, where the weekend theme was ‘Continuous Collaboration for Living Evidence Generation’. Following two days of tutorials and workshops, the community joined together April 20 on the SS Rotterdam for a day of networking, sharing research, and looking ahead to the potential of a global healthcare surveillance system developed by the OHDSI community. All presentations, posters and slides can be found here.
• 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. You will leave with the advanced expertise needed to ensure your data is analysis-ready and capable of generating the reliable evidence required to drive organizational adoption.
• 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.
Job Openings
• The Department of Biomedical Informatics at Columbia University is seeking a highly motivated data science engineer to support large-scale observational research within the OHDSI network. This role will focus on the design, implementation, and execution of distributed network studies using electronic health record (EHR) and administrative claims data to generate real-world evidence. The successful candidate will contribute to characterization, population-level estimation (causal inference), and patient-level prediction analyses across multi-institutional data networks. This position offers a unique opportunity to work at the intersection of biomedical informatics, data science, and clinical research within a leading academic medical center. This position is a full-time two-year position with a possibility of an extension, contingent on available funding.
OHDSI SOCIAL SHOWCASE
Research from the 2025 Global 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 — Bridging Standards: Transforming Consolidated Clinical Document Architecture (C-CDA) Data via Health Information Networks to OMOP (Xiaohan Tanner Zhang)
Tuesday — ARKE: An Ontology-Driven Framework for Standardizing Radiology Procedure Terminology Using LLMs and RAG (Sumin Lee)
Wednesday — Assessing sex-based fairness across patient-level prediction models (Aniek Markus)
Thursday — Cancer Treatment Guidelines Need a Reality Check — RWE Can Help (Asieh Golozar)
Friday — ExCITE: A Containerized Open-Source Platform Integrating EHR, FHIR, and OMOP for Biomedical Informatics Education (Robert Barrett)
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.
