Understanding the Foundations of Interoperability

For years, fragmented health information systems have hindered effective care delivery. Patients often find themselves repeating medical histories, and providers struggle to obtain a complete picture of their patients’ health. Interoperability – the ability of different information systems to exchange and use data – is the key to unlocking a more connected and efficient healthcare ecosystem. The 21^st Century Cures Act mandated the establishment of a universal framework for this exchange, leading to the creation of TEFCA.

TEFCA: A Common Agreement for Nationwide Exchange

TEFCA, overseen by the Sequoia Project, establishes a Common Agreement for network-to-network exchange. It provides a standardized set of policies, connectivity services, and oversight mechanisms for participating health information networks. Think of it as a foundational layer, ensuring that different networks can “talk” to each other regardless of their underlying technology or business model. As of late 2023, TEFCA’s governance has evolved into a robust, participatory model involving both public and private stakeholders. Becoming a Qualified Health Information Network (QHIN) under TEFCA requires meeting rigorous standards, including cybersecurity insurance, third-party security assessments, and U.S. ownership verification.

CMS-Aligned Networks: Accelerating Progress Through Pledges

Recognizing that a one-size-fits-all approach may not suit all organizations, CMS launched its Health Technology Ecosystem pledge program. This program allows networks to voluntarily commit to meeting specific criteria outlined in the CMS Interoperability Framework, demonstrating their dedication to advancing interoperability. Unlike TEFCA, which establishes a centralized governance structure, the CMS-Aligned Network pledge offers a more flexible pathway for networks to accelerate their capabilities. Any organization identifying as a network and agreeing to the framework can participate. In fact, all organizations currently designated as QHINs under TEFCA have also pledged to be CMS-Aligned Networks, highlighting the synergistic relationship between the two initiatives.

How Do TEFCA and CMS-Aligned Networks Work Together?

Both TEFCA and CMS-Aligned Networks share a common goal: empowering patients, providers, and other authorized entities with secure access to electronic health information. TEFCA provides the foundational rules of the road for nationwide exchange, while CMS-Aligned Networks act as “speedboats,” rapidly implementing specific interoperability milestones. CMS actively defines expectations for pledgees and convenes technical working groups to refine criteria and measure success. Pledgees commit to shared goals, contribute to common approaches, and are expected to demonstrate continuous improvement. Participation in CMS-Aligned Networks requires adherence to HITRUST requirements and full compliance with HIPAA and other relevant privacy and security regulations.

Beyond the Basics: Key Differences in Approach

While both initiatives aim to improve interoperability, their approaches differ significantly in pace and structure. TEFCA follows a formal, stepwise governance process, ensuring stability and consistency. CMS-Aligned Networks, on the other hand, embrace a more agile “connect-a-thon” style model, encouraging rapid testing, learning, and refinement. This difference is reflected in the specific criteria each initiative emphasizes. For example, CMS-Aligned Networks are expected to provide a detailed accounting record of all network-facilitated transactions, including who accessed patient data, when, and why. They are also expected to prioritize sharing patient consent preferences with all involved parties.

Furthermore, the CMS Interoperability Framework places a strong emphasis on accelerating access to patient appointment and encounter details, a use case not necessarily central to TEFCA’s focus on cross-network exchange. Both frameworks, however, align on underlying technical expectations, supporting standards like USCDI, HL7® FHIR®, and IAL2/AAL2 for digital identity.

What challenges do you foresee in achieving full interoperability across the healthcare landscape? And how can we best leverage both TEFCA and CMS-Aligned Networks to overcome these hurdles?

Frequently Asked Questions About TEFCA and CMS-Aligned Networks

1. What is the primary goal of the TEFCA framework?

   The primary goal of TEFCA is to establish a common agreement for nationwide health information exchange, enabling different networks to securely and seamlessly share patient data.

2. How does a health information network become “CMS-Aligned?”

   A network becomes CMS-Aligned by voluntarily pledging to meet the criteria outlined in the CMS Interoperability Framework, demonstrating a commitment to advancing interoperability.

3. What are the key technical standards supported by both TEFCA and CMS-Aligned Networks?

   Both initiatives support key technical standards such as USCDI, HL7® FHIR®, and IAL2/AAL2 for digital identity, ensuring a common foundation for data exchange.

4. Is participation in the CMS-Aligned Network pledge program mandatory?

   No, participation in the CMS-Aligned Network pledge program is entirely voluntary. It provides a pathway for networks to accelerate their interoperability efforts but is not a requirement for participation in the broader health information exchange ecosystem.

5. What role does cybersecurity play in both TEFCA and CMS-Aligned Networks?

   Cybersecurity is paramount in both initiatives. QHINs under TEFCA are required to have cybersecurity insurance and undergo annual security assessments, while CMS-Aligned Networks must fully comply with HIPAA and other relevant security regulations.

6. How does the CMS Interoperability Framework differ from TEFCA’s governance model?

   The CMS Interoperability Framework utilizes a pledge-based model, encouraging rapid innovation and testing, while TEFCA employs a more formal, stepwise governance process focused on establishing a stable and consistent framework for nationwide exchange.
