How Better uses FHIR and openEHR for operational data persistence
How we use FHIR for the persistence of operational data? - Better care
Summary
Better explains its system for managing operational data by combining the open standards FHIR and openEHR. This approach allows it to maintain the entire patient record (including demographics and encounters) while also managing organizational master data with high security and scalability.
Details
Better utilizes openEHR as the primary standard in its digital health platform but leverages the FHIR open standard for operational data persistence. The combination of these two standards is increasingly recognized as essential for building future healthcare systems. For the patient record as a whole, since openEHR data is designed to be 'anonymous,' non-clinical information such as demographic details (e.g., name, date of birth) are managed via FHIR Patient data and linked together. Furthermore, encounter information is stored in FHIR Encounter resources and associated with the relevant openEHR data. The Operational Data Repository (ODR) serves as a master data store for operational needs beyond just patient and encounter information. It can manage records such as appointments, healthcare service registries, or professional directories. The ODR adheres to the FHIR standard and fully supports resource profiling, enabling compliance with both local and national constraints and extensions. Additionally, the ODR provides Terminology Services functionality, playing a critical role in creating structured, high-quality health data. Technically, the platform includes capabilities to transform HL7 ADT messages into FHIR, supporting data movement between FHIR, openEHR, and other non-standard formats. This combination results in a flexible platform capable of handling national scale volumes with high security.
