People Also Ask
What is the difference between HL7 v2 and FHIR?
HL7 v2 uses pipe-delimited messages for point-to-point integration, while FHIR uses modern RESTful APIs with JSON/XML for flexible, web-based interoperability. FHIR provides granular resource-based access, standardized data models, and better support for mobile/cloud applications. FHIR is the future of healthcare interoperability mandated by ONC regulations.
How are custom Z-segments converted to FHIR?
Custom Z-segments are converted to FHIR extensions with proper structure definitions. AI analyzes Z-segment usage patterns, generates appropriate extension definitions, and creates StructureMap resources for automated conversion. Extensions maintain semantic meaning while ensuring FHIR compliance and interoperability.
Can you maintain both HL7 and FHIR during transition?
Yes, dual-protocol support allows gradual migration. The system maintains HL7 v2 interfaces for legacy systems while exposing FHIR APIs for modern applications. Bidirectional synchronization ensures data consistency. This phased approach minimizes disruption and allows testing before full FHIR cutover.
Is FHIR migration required for ONC Cures Act compliance?
Yes, the ONC Cures Act Final Rule requires certified EHR systems to support FHIR-based APIs for patient access (21st Century Cures Act). Healthcare organizations must provide patients with API access to their health data using FHIR R4 and US Core profiles. Non-compliance can result in information blocking penalties.
What FHIR version should I migrate to?
FHIR R4 is the current standard for production use, with widespread EHR vendor support and regulatory requirements (ONC, CMS). FHIR R5 offers enhanced features but has limited vendor adoption. We recommend FHIR R4 with US Core 6.1.0 profiles for maximum interoperability and compliance with current regulations.
