OHDSI UPDATES
• The first-ever 2025 OHDSI Africa Symposium is taking place Nov. 10-12 in Kampala, Uganda, and registration is open. The event agenda has been posted on the event homepage.
• The latest edition of the OHDSI newsletter is now available. This edition includes materials from the 2025 Global Symposium (videos, slides, posters), the 2025 edition of the Our Journey booklet, a collaborator spotlight Q&A with Andrew Kanter, recent community updates, publications and presentations from October, and plenty more.
• The latest Our Journey annual report is now on the OHDSI homepage. This 134-page PDF provides an overview of the OHDSI community, including a look at its collaborators and collaborative activities, its research areas and tools, its work with standardized data and vocabularies, and nearly 900 publications that have come from the community.
• There is a new tutorials homepage on OHDSI.org that hosts all tutorials from past Global/US Symposia, as well as tutorials from the SOS Challenge. Future tutorials will also be added here.

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.
Job Openings
• Erasmus MC recently posted job openings for both a Health Data Scientist and a PhD student in medical informatics. More details and an application link are available on the respective pages. The closing date for both positions is Nov. 17.
