Despite advanced digital infrastructure enabling health data exchange across the U.S., the Trusted Exchange Framework and Common Agreement (TEFCA) faces a critical barrier: institutional and human distrust. While technology exists to connect healthcare providers nationwide, the real challenge lies in aligning legal frameworks, clarifying definitions, and fostering confidence among stakeholders.
The core dilemma centers on the interplay of three regulatory forces: the Health Insurance Portability and Accountability Act (HIPAA) Privacy Rule, information blocking regulations, and TEFCA’s own framework. These policies create a “policy triangle” that shapes how healthcare entities share information, but conflicting interpretations and institutional hesitancy have slowed progress.
The Policy Triangle: Permits, Expectations, and Mandates
The HIPAA Privacy Rule permits but does not require healthcare providers to respond to network queries for treatment purposes. This creates a baseline of flexibility but also ambiguity. In contrast, the information blocking regulations change the “you can share” electronic health information posture to a general expectation that “you will share.”
TEFCA adds a third layer. Its Common Agreement for QHINs and Terms of Participation for all other Participants and Subparticipants create binding obligations requiring data sharing among members. However, the framework’s success hinges on resolving longstanding disputes over definitions like “treatment” and “health care provider.”
Stranger Danger: The Trust Gap at Scale
TEFCA’s design aims to automate data sharing between entities that have never collaborated before. To achieve this, it requires participants to agree on standardized definitions and rigorous onboarding processes. However, this “trust at scale” model faces resistance from providers wary of sharing sensitive information with unfamiliar organizations.
The framework includes safeguards, such as a directory infrastructure that restricts queries to authorized purposes and governance mechanisms to detect misuse. Yet, these measures have not fully alleviated concerns, as TEFCA’s scale has led some participating in TEFCA Exchange to give more thought to the “strangers” to whom they’re responding.
Interpretative Drift: The Battle Over Definitions
A key obstacle is the 25 years of divergent interpretations of HIPAA’s “treatment” definition. While the law broadly permits data sharing for care coordination, providers often disagree on what constitutes a valid treatment-related query. When a requester describes its rationale for making a treatment query and a responder disagrees that the request is for “treatment,” we reach an information exchange impasse.
These disagreements ripple through the system. Such conflicts not only delay care but also erode confidence in the network’s reliability.
Building Consensus: The Path Forward
TEFCA’s success depends on resolving these interpretative differences. The framework includes processes for dispute resolution and audits, but participants emphasize the need for clearer guidance.
Meanwhile, the framework’s scale continues to evolve. More than 60,000 locations are now connected through TEFCA, according to the ONC.
What’s Next? The Road to Trust
As TEFCA matures, the focus will shift to building trust through transparency and accountability.
For providers, the challenge remains balancing regulatory requirements with practical concerns.
As the nation grapples with these issues, one thing is clear: the path to nationwide health data interoperability is as much about human relationships as it is about technology.
