OHDSI UPDATES
The latest edition of the OHDSI newsletter is now available, and it highlights the major oncology enhancements featured in the latest vocabulary refresh, shares key updates on OMOP v5.5, and spotlights community leaders Asieh Golozar and Rupa Makadia. As always, the newsletter also includes the latest community updates, publications, and presentations, and it provides the final updates as we get closer to the 2026 Global Symposium.
• Rupa Makadia is a Director in Observational Health Data Sciences at Johnson & Johnson, based in Raritan, New Jersey. Her work focuses on generating real-world evidence to evaluate the safety and effectiveness of medical products, with particular emphasis on oncology and pregnancy research. She leads the Perinatal and Reproductive Health Workgroup, fondly known as PRHeG, within the OHDSI community and contributes to methods development and network studies. Rupa holds a PhD in Biomedical Informatics from Rutgers University, an MS in Biostatistics from California State University, East Bay, and a BS in Biology from Cal Poly, San Luis Obispo. A longtime OHDSI member, she has helped advance cross-network initiatives and research throughout the community. Rupa discusses her career journey and research interests, upcoming initiatives for the Perinatal and Reproductive Health Workgroup, the OHDSI approach and more in the latest edition of the Collaborator Spotlight.
• 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.
OHDSI SOCIAL SHOWCASE
