How We Actually Build This
FHIR-compliant APIs expose and consume patient data using standardized resource types (Patient, Observation, MedicationRequest) that any FHIR-compatible system can interpret consistently
Integration handles the reality that many existing systems still run older HL7 v2 messaging, requiring translation between the legacy and modern standards during a transition period
Patient consent and access control govern exactly what data flows between systems, since interoperability doesn’t mean unrestricted data sharing — patients and regulations still govern who can access what
Data mapping reconciles the reality that different EHR systems, even both FHIR-compliant, often use fields and terminology inconsistently, requiring careful normalization
Key Benefits
Why This Matters for Healthcare & Telemedicine
Enables a more complete clinical picture across previously siloed systems
Standardized API-based exchange is far more maintainable than legacy point-to-point integrations
Reduces redundant testing and data entry from information not following the patient
Supports the broader industry and regulatory push toward genuine healthcare interoperability
Proven at Scale
Who’s Building on This
Epic & Cerner (Oracle Health)
the two dominant EHR platforms, have both adopted FHIR as their standard interoperability API
Where This Applies
Common Use Cases
- Health systems integrating multiple EHR platforms
- Telehealth platforms needing access to a patient’s existing medical history
- Health apps and wearables sharing data with clinical systems
- Health information exchanges connecting providers across a region
Frequently Asked Questions
Common Questions About HL7/FHIR-Based EHR Interoperability
What is the difference between HL7 v2 and FHIR?+
HL7 v2 is an older messaging standard, widely deployed but rigid and difficult to extend; FHIR is the modern, API-based standard built for the way software is actually built today, offering easier integration — many healthcare systems still run both, requiring interoperability solutions to bridge the two.
Does FHIR compliance mean any two systems can automatically share data seamlessly?+
Not entirely — while FHIR standardizes the technical format and API structure, real-world systems still often use fields and terminology inconsistently, meaning genuine interoperability typically requires additional data mapping and normalization work beyond simply "being FHIR-compliant."
Who controls what patient data actually gets shared between systems?+
Patient consent and regulatory requirements (like those under HIPAA) govern data sharing — FHIR provides the technical mechanism for exchange, but the decision of what’s shared, with whom, and under what authorization is a separate governance and compliance layer built on top of the technical standard.
