FHIR API Strategy for Health Systems: Build vs. Extend vs. Integrate
FHIR API Strategy for Health Systems: Build vs. Extend vs.
null
Summary
As healthcare organizations upgrade their IT ecosystems, adopting the HL7 FHIR standard for APIs is critical. This article compares three FHIR strategies—building custom solutions, extending existing platforms, and integrating with third-party services—detailing the benefits and optimal use cases for each approach.
Details
When health systems advance their IT infrastructure to meet unique needs, adopting the HL7 FHIR standard API becomes essential. However, choosing a specific implementation strategy among 'building from scratch,' 'extending an existing platform,' or 'integrating with third-party services' can be challenging. **1. Build (Custom Solution):** Offers maximum control and flexibility but requires significant resources due to long development timelines (6–12 months for core development) and continuous maintenance/security patching. It allows for custom extensions and unique business logic implementation. **2. Extend (Existing Platform):** Involves customizing a pre-built FHIR server. This approach reduces initial investment and time compared to building from scratch, while still allowing functional additions (profiles or extensions). Shared maintenance with the platform provider is required. **3. Integrate (Third-Party Services):** Utilizes external FHIR APIs provided by vendors (EHRs, HIEs). This offers the fastest deployment and minimizes initial technical risk because hosting, security, and upgrades are handled by the supplier. Focus can be placed on application layer improvements. Comparing these options provides a framework for organizations to determine the best strategy based on their available resources, timeline, and required flexibility.
