2019 OHDSI U.S. Symposium

The 5th annual OHDSI U.S. Symposium welcomed both veterans and new collaborators to the the Bethesda North Marriott Hotel & Conference Center on Sept. 16, 2019. The day opened with an introductory address and plenary talks surrounding real-world evidence, while the afternoon featured talks on community evidence in action and a closing talk on the 10-year history of the OMOP Common-Data Model and a challenge for the future of the OHDSI community.

Check out a full photo recap of the day!

The middle of the day featured the annual collaborator showcase, which included seven lightning talks, nearly 80 poster presentations and several software demos. The research highlights this year by OHDSI collaborators were inspirational, and you can find them all below on our virtual showcase page.
