Welcome To OHDSI
Observational Health Data Sciences and Informatics (OHDSI, pronounced “Odyssey”) 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, OHDSI is a growing collaborative of more than 2,700 researchers across disciplines, stakeholders, and geographies. OHDSI also has established an international distributed data network that applies one open community data standard and collectively contains data for more than 810 million patients around the world, and has produce a suite of open-source software packages that enables the community to translate that data into reliable evidence.
OHDSI collaborates to establish open community data standards, develop open-source software, conduct methodological research, and apply best practices across the OHDSI data network to generate clinical evidence.
OHDSI’s research has been presented across various scientific societies and published in top medical journals. Our growing global community is always seeking new collaborators. We hope you are interested to Join The Journey!

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.
