Welcome to OHDSI!
The Observational Health Data Sciences and Informatics (or OHDSI, pronounced "Odyssey") program is a multi-stakeholder, interdisciplinary collaborative to bring out the value of health data through large-scale analytics. All our solutions are open-source.
OHDSI has established an international network of researchers and observational health databases with a central coordinating center housed at Columbia University.
Read more about us, about our goals, and how you can help support the OHDSI community.
2021 OHDSI Symposium
The 2021 OHDSI Global Symposium featured plenary presentations on OHDSI’s Impact on the COVID-19 Pandemic, as well as on the Journey to Reliable Evidence. The main days included the State of the Community Presentation, the Collaborator Showcase, and a memorable Closing Ceremony that focused on OHDSI’s work through the perspective of a patient.
There were also a pair of full-day activities, including the first OHDSI Reproducibility Challenge workshop, and a tutorial on building concept sets. Use the link button below to see the recordings, posters and more.
