Welcome To OHDSI
The OHDSI research community strives to promote better health decisions and care through globally standardized health data, continuously developing large-scale analytics and a spirit of collaboration though open science.
Founded in 2014, the Observational Health Data Sciences and Informatics (OHDSI, pronounced “Odyssey”) initiative has both a growing network of interdisciplinary researchers from six continents, as well as standardized health records for nearly 600 million unique patients around the world.
OHDSI studies in the areas of clinical applications and methodological research have been published in the world’s top medical journals, including The Lancet, Journal of Biomedical Informatics, and JAMIA.
OHDSI also provides support to regulatory agencies. The EMA cited OHDSI methods in its most recent guidelines around scientific best practices, while the U.S. FDA awarded a $10 million contract to OHDSI in 2020 to provide support to the BEST program around vaccine surveillance.
Our growing community always seeks new collaborators. Please learn more about us through this web site and Join The Journey!
Join The Journey
As a community, we are collaborating towards improving health outcomes for patients around the world. To achieve this goal, we are developing open-source analytic tools and generating high-quality evidence to inform medical decision making.
Whether you’re a software developer, physician or clinical researcher, there is a place for everyone in the OHDSI community.
Want to Join The Journey? Here are a few ways you can get started!

OHDSI on YouTube
OHDSI presentations, tutorials, short features and more are posted to our YouTube page. A sample of those videos are below, but please visit our YouTube page for access to our complete library of materials.
Stay Connected
The weekly OHDSI community calls are a great way to stay updated and involved with network activities. These meetings include research presentations, idea sharing, community updates and plenty more. Everybody is invited!
Our next call will be Tuesday, April 20 (11 am ET) and will focus on “Local Impacts of OHDSI.”
We often discuss the global network studies ongoing in OHDSI, but there are important impacts happening within local institutions as well, either through the adoption of the OMOP CDM and/or use of OHDSI tools. We are excited to hear local success stories from Alison Callahan and Jose Posada (Stanford University), Lisa Schilling (University of Colorado Denver), and Karthik Natarajan (Columbia University).
Our calls are recorded weekly and posted to our community calls page, which also includes the upcoming schedule and a link to join.
2021 Global Symposium
We are excited to announce that general registration for the 2021 Global OHDSI Symposium, which will be held virtually in Microsoft Teams, Sept. 12-15, is open! This will be our seventh annual OHDSI Symposium, and it will provide another opportunity for our community to come together, share ideas, learn from each other and network with our fellow collaborators.
