OHDSI

The Observational Health Data Sciences and Informatics (OHDSI) initiative is a global, open-source community dedicated to improving the use of real-world evidence (RWE) in healthcare. Founded in 2012, OHDSI aims to facilitate the generation and application of RWE to improve patient care, research, and policy.

OHDSI's primary focus is on developing and sharing tools and resources that enable the analysis of large,

The OHDSI community is composed of researchers, data scientists, healthcare professionals, and industry partners who collaborate

OHDSI's work has been instrumental in advancing the use of RWE in various domains, including pharmacovigilance,
