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.
