What is TEFCA and why does it matter for Health Tech infrastructure?

TEFCA is a U.S. framework for nationwide health information exchange, establishing Qualified Health Information Networks (QHINs) to standardize data sharing. It matters because it reduces integration complexity and provides a consistent rail for clinical data to move across states and vendors, enabling analytics and care coordination at national scale.

How are cloud providers changing hospital data architecture?

Cloud providers such as Microsoft, Google Cloud, AWS and Oracle are delivering healthcare-specific services that harmonize FHIR and imaging datasets, secure PHI, and accelerate AI workloads. Health systems are adopting these platforms to unify data models, shrink infrastructure overhead, and tie clinical workflows to scalable compute and storage.

What did the Change Healthcare cyberattack reveal about infrastructure risk?

The Change Healthcare attack exposed systemic vulnerabilities in claims processing and interoperability pipes, leading to multi-week disruptions and billions in estimated costs. It accelerated investment in zero-trust segmentation, immutable backups, and rapid recovery playbooks, shifting cybersecurity from an IT line item to a board-level infrastructure priority.

Where do data-layer platforms like Snowflake and Databricks fit in?

These platforms act as the analytical backbone, normalizing and governing multimodal health data at scale and integrating with EHRs via networks like Redox. They support TEFCA-enabled exchange by providing secure landing zones for longitudinal patient records, enabling actionable insights without duplicating sensitive data across systems.

What’s the near-term outlook for AI at the point of care?

Expect increased edge deployments for imaging and documentation, connected to cloud data layers for retraining and governance. Regulators are clarifying AI/ML lifecycle controls, and hospital teams will favor architectures that balance low-latency decision support with strong privacy, auditability and standardized FHIR pipelines.

TEFCA Switch Flips as Epic and Oracle Rewire Health Data Rails; $1.6B Breach Spurs Overhaul

Hospitals are rebuilding their data backbones as TEFCA’s first national exchange networks go live and cloud providers deepen their healthcare stacks. Epic, Oracle, Google Cloud and AWS push new infrastructure, while the Change Healthcare hack’s $1.6 billion price tag jolts cybersecurity investment.

Cloud Backbones Get Reengineered

Major health systems are accelerating migrations to dedicated healthcare clouds as infrastructure becomes the competitive battleground for Health Tech. Oracle continues moving legacy Cerner workloads to Oracle Cloud Infrastructure, pitching unified data models and a single patient record across venues of care. In parallel, Epic customers are expanding use of Azure services via Epic’s deepening ties with Microsoft, including ambient clinical documentation and data services.

The cloud race is widening beyond hyperscalers. Data-layer vendors like Snowflake and Databricks are anchoring longitudinal patient datasets with healthcare-specific governance. Integration networks such as Redox are increasingly positioned as critical plumbing between EHRs and analytics platforms, easing FHIR and HL7 traffic at scale.

Partnerships are turning into infrastructure commitments. Microsoft’s tie-up with Epic brought Azure OpenAI into clinical workflows, according to the companies. Meanwhile, Google Cloud is advancing its Healthcare Data Engine for harmonizing multimodal datasets, with recent expansions detailed in a Google Cloud update. Amazon Web Services is pushing HealthLake for FHIR-native architectures, as providers standardize on data models that can span research, operations and care delivery.

Interoperability Goes National Under TEFCA

With the Trusted Exchange Framework and Common Agreement (TEFCA) moving from policy to production, the first Qualified Health Information Networks (QHINs) are standing up national-scale exchange. The Office of the National Coordinator highlights the program’s rollout and governance on its TEFCA site, with early participation from networks operated by Epic, Health Gorilla, Kno2, MedAllies and eHealth Exchange.

For enterprise CIOs, TEFCA narrows the complexity of multi-state data exchange and enables standardized routing for clinical summaries, imaging and lab results. That simplification is expected to reduce interface build-outs and maintenance overhead while improving data liquidity for referral management and population health.
