WEEKLY COMMUNITY CALL MEETINGS
ATLAS is a free, open-source, web-based platform that allows researchers to explore standardized healthcare data. It works with the OMOP Common Data Model to let users browse medical vocabularies, define specific patient cohorts, and conduct population-level effect estimations or patient-level predictions without needing direct database access. ATLAS workgroup lead Christopher Knoll will guide us through a preview of ATLAS 3.0 during our July community call (11 am ET).
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.

Núñez-Benjumea, and Alberto Jiménez-Martín on the recent publication of OHSIRIS: A Federated Data Space for Interoperable Biomedical Research in Volume 338 of Studies in Health Technology and Informatics: Health Sciences Informatics Leads and Empowers the Digital Health Transformation.
• Congratulations to the team of Somayeh Abedian, Diego Boscá, and Severin Kohler on the recent publication of Interoperability-Driven Digital Twins in Healthcare: A Conceptual and Technical Analysis of FHIR, openEHR, and OMOP in Volume 338 of Studies in Health Technology and Informatics: Health Sciences Informatics Leads and Empowers the Digital Health Transformation.
• Congratulations to the team of Falk Meyer-Eschenbach, Martin Vogel, Philipp Jacob, Severin Kohler, Louis Agha-Mir-Salim, Loreen Ruhm, Christof von Kalle, Elias Grünewald, Oliver Kumpf, and Felix Balzer on the recent publication of LLM-Assisted Clinical Data Harmonization: Combining Automated ETL Generation with Semantic Vocabulary Mapping for OMOP CDM in Volume 338 of Studies in Health Technology and Informatics: Health Sciences Informatics Leads and Empowers the Digital Health Transformation.
• Congratulations to Dani Prieto-Alhambra, who was recently announced as the first Oxford Professor of Regulatory Health Data Science at NDORMS. The new professorship strengthens the department’s leadership in health data science and real-world evidence and will specifically support regulatory frameworks and decision making to bring new safe, efficient and effective treatments to benefit patients and society.
OHDSI UPDATES
Clair Blacketer will present her Erasmus MC PhD defense Wednesday at 7 am ET/1 pm CET on Strengthening the Foundations of Real-World Evidence. You can watch the defense live here.
• The latest edition of The Journey Newsletter is now available, and it includes all the LLM-focused presentations from last month. This issue is also packed with essential updates, including our latest June publications and community spotlights on Melanie Philofsky and Sulev Reisberg. We also looked ahead to the first LATAM Symposium and announced the dates for the APAC Symposium.
• 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:

Wednesday — The landscape of OMOP-mapped real-world data sources in the HMA-EMA Catalogues of real-world data sources and studies (Aikaterini-Christina Deli)
Thursday — Disease-aware Harmonization of Parkinson’s Disease Research Data to the OMOP Common Data Model: A Systematic Methodology from AI-PROGNOSIS (Petros Demetrakopoulos)
Friday — Modular recommendation system and review application for semantic mapping (Freija Descamps)
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 for the 2026 OHDSI Global Symposium, held Oct. 20–22 at the Hyatt Regency in New Brunswick, N.J is open! You can also read more about our 12 new tutorial offerings which will take place during Day 1 of the event.
