OHDSI WebAPI is an application, with several RESTful services, that you can use to access 1 or more databases for querying OMOP Common Data Model (CDM) data. WebAPI is developed by Observational Health Data Sciences and Informatics (OHDSI), an interdisciplinary collaborative program making analytics on large-scale health data possible.

WebAPI is a vast topic. It has many features that correspond to observational patient data, which aren’t in the scope of this blog. The focus of this article is to dissect WebAPI to show how it communicates with different CDM databases. We also explain the addition of the SAP HANA database to the list of existing ones.

When it comes to research, a clinical common data model is an important part of any health organisation. Collaborative research and data sharing, with appropriate security and data privacy measurements on the common data model, empowers organizations to work together to improve patient outcomes.

Data4Life’s Analytics Platform for Research leverages the Observational Health Data Sciences and Informatics (OHDSI) Observational Medical Outcomes Partnership (OMOP) common data model (CDM) to enable standardized analysis across different data modalities on collaborative research and data sharing.
