Who we are and why we exist
What OHDSI is, what we do in Latin America, our mission and how the community is organized — all on one page; the sub-navigation above jumps to each block.
A global, open and collaborative scientific community
OHDSI (Observational Health Data Sciences and Informatics, pronounced “Odyssey”) is dedicated to generating reliable evidence from observational health data. Through the OMOP Common Data Model and an ecosystem of open-source tools (ATLAS, HADES, Achilles, WhiteRabbit…), the community promotes reproducible, transparent and interoperable studies, connecting institutions worldwide.
More than 4,700 collaborators across 88 countries, with standardized data from 550+ sources representing nearly one billion patient records. Global coordination is based at Columbia University's Department of Biomedical Informatics.

Why we exist
To empower the Latin American community to collaboratively generate scientific evidence from observational data to improve health decisions.
A Latin America in which real-world data is used with quality, scale and responsibility to reduce inequalities and improve population health.
Standardization with the OMOP CDM, open governance, reliable comparative methods and network studies with transparency and reproducibility.
How the community is organized
OHDSI Latin America was born from global OHDSI's Latin America Workgroup and is organized around regional leadership, national nodes and thematic groups. All communication happens on OHDSI's MS Teams, in open channels.
