• The Common Data Model working group has been planning CDM v5.5 over the last 18 months and there is now a development version to share. Please take a look, review, and test in your environment if you are able. This version will be released alongside the August 2026 vocabulary and will support community needs and continued vocabulary updates.
• Registration is open for the 4-day OMOP School in Uppsala, Sweden on Oct. 13-16. There are fewer than 10 spaces remaining, so don’t wait until the final moment to register.
• The CDM Survey Subgroup has shared a Best Practices for Mapping Standardized Assessment Instrument Data to the OMOP Common Data Model protocol. Learn more via the full proposal or this slidedeck. Please review and comment by Aug. 27.
• 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.
• 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.
