The Observational Health Data Sciences and Informatics (or OHDSI, pronounced "Odyssey") program is a multi-stakeholder, interdisciplinary collaborative to bring out the value of health data through large-scale analytics. All our solutions are open-source.

OHDSI has established an international network of researchers and observational health databases with a central coordinating center housed at Columbia University.

Mission: Improving health by empowering a community to collaboratively generate evidence that promotes better health decisions and better care

Vision: Creating a world in which observational research produces a comprehensive understanding of health and disease

Values: Innovation, Reproducibility, Community, Collaboration, Openness, Beneficence

OHDSI strives to develop reliable real-world evidence through methodological research, open-source analytics development, and clinical evidence generation.
