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.
