Background

The UNSW ePBRN has developed a data repository of linked pseudonymised patients derived from electronic health records of general practices and hospitals in an integrated health neighbourhood in SW Sydney. The Observational Health Data Science Informatics (OHDSI) community is an established international network of researchers and observational health databases with a central coordinating center housed at Columbia University (www.ohdsi.org). The Observational Medical Outcomes Program (OMOP) Common Data Model is central to OHDSI. 

Objective

This project mapped observational data from the ePBRN dataset to similar data sets in the international EHR-derived datasets through the OMOP Common Data Model.
