• The second OHDSI Maternal Health Fellowship is designed to train clinical investigators for improved maternal and neonatal care. This fellowship offers three key components: Career Development, Practice, and Networking. Supported by both the OHDSI community and the NIH IMPROVE initiative, the program focuses on training clinical investigators in observational research methods to enable them to conduct reproducible research and generate real-world evidence. Learn more and register here. The deadline to apply is May 15.
• Ready to turn your data harmonization vision into reality? Join The OMOP School in Stockholm, Sweden May 26-29 for a hands-on bootcamp designed to help you master the OMOP Common Data Model and execute end-to-end mini-harmonization projects. Whether you are a data scientist, researcher, or health data custodian, this intensive workshop provides the actionable tools and OHDSI methods needed to transform your institutional research capabilities.
• 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. Please help the organizing committee identify relevant stakeholders to represent the region; reach out to [email protected] or [email protected] to provide assistance.
• The OHDSI community has published more than 950 peer-review studies highlighting the OMOP CDM or OHDSI tools. Learn more about OHDSI research via our improved Community Dashboard. Thank you to our collaborators at Johns Hopkins for leading this initiative.
• Registration is now open for the 2026 Summer School in Observational Health Data Science & Informatics, AI, and Real World Evidence, which will be held June 22-26 at the Columbia University Department of Biomedical Informatics. Now in its second year, the Columbia OHDSI Summer School provides health professionals, researchers, and industry practitioners with an immersive, hands-on training to working with real-world health data and generating real-world evidence (RWE). Participants will explore the types of healthcare data captured during routine clinical care—such as electronic health records and administrative claims—and learn how to standardize these data using the OMOP Common Data Model to support collaborative, distributed research as part of a data network.
