Observational Health Data Sciences and Informatics

Research Partner

In June 2022, the Observational Health Data Sciences and Informatics (OHDSI) community and SNOMED International formalized their long-time relationship with a five-year collaborative agreement that will benefit both of their user communities.


The collaboration provides OHDSI and its user community with comprehensive ontologies on specific healthcare domains and content such as devices, social determinants of health, disease severity scores and modifiers of cancers, as well as better concept definitions and resolutions of composite concepts in large-scale observational research. 

Additional information

Effective April 29, 2022, the collaboration provides OHDSI and its user community with comprehensive ontologies on specific healthcare domains and content such as devices, social determinants of health, disease severity scores and modifiers of cancers, as well as better concept definitions and resolutions of composite concepts in large-scale observational research. In return, OHDSI and its user community can provide SNOMED International with information and feedback on clinical validation, frequency of use data, and validation of SNOMED CT content modeling. Ultimately, continuous feedback shared regarding identified content gaps will benefit both user communities as we move forward together.

The collaboration supports SNOMED International’s Member and stakeholder-driven five-year strategy, which includes genomic content collaboration as well as engagement with the research community. The work of OHDSI looks to showcase the use of SNOMED CT for the purposes of data analytics, supporting both healthcare research and audit, with the aim of enhancing healthcare globally.
