This Week in OHDSI

June 16, 2026

Generative AI and Large Language Models (LLMs) have the potential to massively accelerate our research mission, and we are seeing incredible breakthroughs across our global community. Our June 16 community call held the third of a special three-part series dedicated to LLM research in OHDSI:

  • Study Agent support for users of Hades (Richard Boyce, University of Pittsburgh)
  • FastSSV, a semantic static validator for LLM Generated queries (Shihao Shenzhang, King’s College, London)
  • Implementation of foundation models in the Trøndelag Health Study (Brooke Wolford, Norwegian University of Science and Technology / University of Oslo)
  • FastOMOP: Agent Harness and Ecosystem for RWE (Vishnu V Chandrabalan, Lancashire Teaching Hospitals NHS Foundation Trust)

Community Updates

• Congratulations to the team of Jens Declerck, Mieke Deschepper, Kirsten Colpaert, Dipak Kalra, and Pascal Coorevits on the recent publication of Addressing Data Quality Challenges in Lung Cancer Data Within the Observational Medical Outcomes Partnership Common Data Model: Observational Study in the Journal of Medical Internet Research.

• Congratulations to the team of Youngsun Park, Yukyeong Son, Nara Sun, Jungkyun Woo, Soo-Yong Shin, Hong Seok Park, Dosang Cho, Kyung-Jae Lee, and Hannah Kang on the recent publication of Implementing a quality assurance and maintenance framework for standardized clinical terminology data in a multi-institutional setting in BMC Medical Informatics and Decision Making.

• Congratulations to the team of F X Avilés-Jurado, I Valduvieco, S Medrano-Martorell, A Muxí, J Lop, F J Cuesta, N Cuesta, A Ferrer-Fuertes, E Lehrer, M Lopez-Chacon, M J Rojas-Lechuga, M Molins-Vigatà, G Castells, A Dieguez, D García, C Ares, C Climent, M Mazariegos, A Cabero, M Egea, N Bartolomé-Cerdà, Y Rodriguez, A Massuet, S Vazquez, C Sampieri, J M Costa-González, R D Ramírez, E Palou, O Rubio, M T Martín, M Castella-Tarrés, L Heredia-Aguilar, M Mollà, M Bernal-Sprekelsen, A Prat, F Feu, A Castells, and I Vilaseca on the recent publication of Comprehensive Cancer Centre Accreditation: Experience and Achievements of a Head Neck Cancer Unit in Acta Otorrinolaringologica.

• Congratulations to the team of Larson Hogstrom, Arvydas Laurinavicius, Miguel Giraldez Alvarez, Sigve Nakken, Ingrid Jenny Guldvik, Carlos Miguez Sanchez, Olga Papadodima, Konstantinos Voutetakis, Per Magnus Mæhle, Norman Zerbe, Mario Šekerija, Ane Fullaondo, and Eivind Hovig on the recent publication of European cancer data sharing: Analyses of an international survey in the International Journal of Medical Informatics.

• 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. Registration is now OPEN.  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.

Upcoming 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.

• 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.

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 — Democratizing Critical Care Research: A Portable dbt and DuckDB Pipeline for MIMIC-IV to OMOP CDM Conversion (Adam Sutton)
Tuesday — A Patient-Centric OMOP-CDM Partitioning Tool for Federated Deployment Testing (Narasimha Raghavan Veeraragavan)
Wednesday — Evaluation of the Preparative Phase Readiness in OikoLexis (Michel J.F. Walravens)
Thursday — DARWIN EU® – A transportable framework for evaluating pregnancy episode algorithms in heterogeneous real-world databases (Aniek Markus)
Friday — DARWIN EU® – Clozapine and the incidence of agranulocytosis over time (Ellen Gerritsen)
