Observational Medical Outcomes Partnership (OMOP)

The legacy i2b2 data model is comprised of a central fact table (observation_fact) surrounded by multiple dimension tables (star schema). In the Observation Medical Outcomes Partnership (OMOP) Common Data Model (CDM) rather than a central fact table, we have a collection of them distinguished by domain: procedures, condition, drug, measurement, observation, etc. In this project, we modify the CRC to run queries against multiple domain fact tables as dictated by the metadata.The data models of i2b2 and OMOP have many similarities.  We take advantage of these similarities to construct an evolution of the i2b2 software that is able to adapt to the OMOP data model.   This adaption of i2b2 allows the query formulation Application Programming Interface (API) to be implemented over an OMOP data source.  Therefore, most of the functionality of i2b2 Software is preserved on OMOP data sources, and as a result the SHRINE and SMART-on-FHIR tools that rely on the i2b2 API are also able to run on the OMOP data model.
