What it means

FHIR (pronounced "fire") represents clinical concepts as discrete resources accessed through RESTful APIs, making health data far easier to integrate with modern apps. ONC certification requires standardized FHIR APIs for patient and population access, so a certified occupational-health record can connect to HRIS, clinical EHRs and partner apps with far less custom interface work.
