Healthcare interoperability — the ability for different health IT systems to exchange and use patient data seamlessly — has been a central policy conversation for years. What began as conference-room debates at events like VIVE and HIMSS has become federal mandate.

Key Takeaways

  • The 21st Century Cures Act and information blocking rules transformed how health data is shared
  • TEFCA (Trusted Exchange Framework) is now operational, enabling nationwide data exchange
  • FHIR APIs have become the standard for health data interoperability
  • Challenges remain around data quality, patient matching, and behavioral health records

The Policy Landscape

The 21st Century Cures Act set the foundation by prohibiting information blocking — the practice of health IT vendors or providers restricting access to electronic health information. The ONC's information blocking rule, fully enforced since 2024, requires that patients can access their complete health records electronically.

TEFCA (Trusted Exchange Framework and Common Agreement) went live in 2024, creating a universal framework for health information exchange across organizations. By 2026, major EHR vendors, health systems, and payers have joined as Qualified Health Information Networks (QHINs).

Where We Are Now

The adoption of FHIR (Fast Healthcare Interoperability Resources) APIs has been the technical breakthrough making this possible. Patients can now pull their records from most major health systems into apps of their choosing. Providers can query patient history across networks in near-real-time.

Remaining Challenges

  • Patient matching — Without a national patient identifier, matching records across systems remains error-prone
  • Data quality — Interoperable doesn't mean accurate; garbage in, garbage out
  • Behavioral health carve-outs — Stricter privacy rules (42 CFR Part 2) still complicate sharing of substance use records
  • Small practice adoption — Rural and independent practices lag in implementing modern APIs

Frequently Asked Questions

What is healthcare interoperability?

Healthcare interoperability is the ability of different health information systems, devices, and applications to access, exchange, and cooperatively use patient data in a coordinated manner across organizational boundaries.

What is FHIR?

FHIR (Fast Healthcare Interoperability Resources) is a standard for exchanging healthcare data electronically. Developed by HL7, it uses modern web APIs (RESTful) to make health data more accessible and interoperable.
