Founded in 2014, the Observational Health Data Sciences and Informatics (OHDSI, pronounced “Odyssey”) initiative grew out of the successful Observational Medical Outcomes Partnership (OMOP). OHDSI is a multi-stakeholder, interdisciplinary, open-science collaborative to bring out the value of health data through large-scale analytics.
With more than 2,000 collaborators across 74 countries and health records for about 810 million unique patients from around the world, OHDSI seeks to improve health by empowering a community to collaboratively generate the evidence that promotes better health decisions and better care. OHDSI’s data network is based on its OMOP common data model, enabling federated analytics amongst collaborators.
OHDSI has established an international network of researchers and observational health databases with a central coordinating center housed at Columbia University. You can learn more about OHDSI through the Book of OHDSI, or through the Our Journey publication, which serves as an annual report of community progress.
Our workgroups present opportunities for all community members to find a home for their talents and passions, and make meaningful contributions. We are always looking for new collaborators. Learn more about these workgroups by checking out our workgroups homepage. Any workgroup that provided a community call update is highlighted in the top section.
A great way to connect with the community is to join our weekly community calls, held Tuesdays at 11 am ET. These calls are meant to inform and engage our community through a variety of call formats, including community presentations, working group updates, breakout sessions, focus topics, newcomer-focused sessions, and more. The community calls homepage (linked above) has recordings from previous presentations, as well as a link to join the weekly call.
