WEEKLY COMMUNITY CALL MEETINGS
The OHDSI Workgroup Spotlight series continues July 22 when Melanie Philofsky and Evan Minty lead sessions on both the Health Systems Interest Group and the Surgery and Perioperative Medicine Workgroup. Join us to hear about both the accomplishments and research goals for these two groups and see if they fit any of your own interests or passions.
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.

OHDSI UPDATES
The annual “Welcome OHDSI Newcomers” community call will be held July 28. If you are relatively new to the community or hope to have a bigger role, this is a great opportunity to introduce yourself. Please tell us who you are and where you work, what are your research interests, how you hope to help the community, and how OHDSI can help your own research journey. For scheduling purposes, please note your interest in taking part in this brief survey.
• Jenna Reps recently posted a call for developers with knowledge or interest in R or shiny or web development/design and UI and want to help out with HADES development in a new workgroup. If you are interested, please respond to the forum post.
• Peter Hoffmann provided a preview of the ATLAS 3 demo site during the July 7 community call. The ATLAS workgroup is looking for feedback about the new site. The demo is available here (Db Authenticaton enabled: use ohdsi/ohdsi, and anonymous access will be enabled in a future update). Discussions will be held here. Thank you for collaborating on this critical open-source tool for our community.
• 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.
• 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:

Wednesday — Comparison of machine- and expert-based mapping of lab test data in a nationwide register (Petteri Hovi)
Thursday — Bridging OMOP patient records and patient supplement files through object storage solutions (Frederic Jung)
Friday — Design and Implementation of an Automated OMOP Database Migration Tool from PostgreSQL to SQL Server (Mandickel Donnex Kamtengeni)
