High Performance Computing on Flat FHIR Files Created with the New SMART/HL7 Bulk Data Access Standard.

The FHIR Bulk Data API is designed to create a uniform capability for population-level exports from clinical systems, into a file format often referred to as "Flat-FHIR." Leveraging the SMART backend services authentication and authorization profile, the approach enables healthcare providers and organizations to define and access cohorts from electronic health records and payor claims data with "push button" simplicity--a substantial advance over the current state, where each site of care needs highly skilled extraction transform and load (ETL) efforts.
