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.

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.
