WEEKLY COMMUNITY CALL MEETINGS
Join us for an expanded OHDSI Workgroup Spotlight as Oncology WG lead Asieh Golozar leads a deep dive into the full spectrum of oncology research across our community during the Aug. 11 (11 am ET) community call. Discover the latest advancements in standardized cancer data, analytical tools, and collaborative observational studies driving precision oncology forward. Bring your questions for a Q&A session at the end of the presentation.
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.

Upcoming Workgroup Calls – OHDSI
OHDSI SHOUTOUTS
Congratulations to the team of David Kern, Justin Bohn, James Gilbert, Christopher Knoll, and Patrick Ryan on the recent publication of REWARD—an open-source framework for identifying the unknown benefits of existing medications to inform drug discovery, development, and repurposing in JAMIA.
• Congratulations to the team of Elizabeth Sherwin, Benjamin Martin, Xiao Xu, Anna Booman, Alyssa Howren, Kimberlee McKay, Sadaf Kazi, Sean O’Reilly, Katie Kolla, Khyzer Aziz, Katherine Bianco, and Stephanie Leonard on the recent publication of Congenital heart disease in pregnancy and severe maternal morbidity: A distributed data network study in Pregnancy.
• Congratulations to the team of Jing Wang-Silvanto, Mansee Jajoo, He Guo, Rishi Ohri, Judith Nelissen, and Carolina Casañas i Comabella on the recent publication of Evaluating AI Performance in Systematic Literature Reviews for HEOR: A Case Study in the Journal of Health Economics and Outcomes Research.
OHDSI UPDATES
The August edition of The Journey newsletter is now available. Check out the enhancements coming in ATLAS 3.0, learn more about a record-breaking Global Symposium showcase, check out an impressive collection of updates and publications from July, as well as spotlights on Maxim Moinat and Misha Khitrun, and plenty more.
• Maryia (aka Masha) Khitrun is the Technical Lead of the OHDSI Vocabulary team at Odysseus Data Services (an EPAM company), based in Vilnius, Lithuania. A medical doctor by training, she brings hands-on clinical experience to her work in health informatics. Masha started her career in OHDSI as a junior data analyst performing concept mappings and has grown into her expertise in vocabulary development and support, step by step. In the latest edition of the Collaborator Spotlight, Masha discusses her career journey, the challenges and importance of maintaining standardized vocabularies, new processes to enhance community contribution, and plenty more.
• 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 for the new REVEAL (Results Enhancements & Visualization for Evidence, Analysis & Learning). If you are interested, please respond to the forum post or sign up here.
• 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.
• Jiwoo Seo, a PhD student at Florida State University, announced a study on the motivations that drive experts to continuously contribute to biomedical ontology communities like OHDSI. You can take part in this survey here.
• 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 — Transforming 5 Billion Rows of Healthcare Data: A Secure, Locally Deployed Open-Source Pipeline for OMOP CDM (Karlo Pintarić)
Tuesday — Lateral specific concept mapping from ICD-10 to SNOMED CT: addressing information loss (Vojtech Huser)
Wednesday — Structural alignment of LOINC hierarchy for standardized representation (Maryia Rahozhkina)
Thursday — Launching OMOP Implementation on Swedish Health data – Tools and Workflows (Stefano Rapisarda)
Friday — A Zero-Trust National Framework for Modular OMOP ETL Deployment and Scalable Analytical Execution in Portugal (Renata Silva)
OHDSI UPCOMING EVENTS
The UK Symposium will be held September 18 at the University of Nottingham, preceded by an OMOP Training Day on September 17.
• Registration is 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 and workgroup activities which will take place during the event.

Registration is open 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. Please check the event homepage for details on the agenda and collaborator showcase.
• The third annual OHDSI India Symposium has been scheduled for December 11th in Chennai. More details and registration information will be shared with the community as they become available.
