The Leading Edge Acceleration Projects (LEAP) in Health IT program issued a Special Emphasis Notice (SEN) for 2025. The SEN will fund two areas of emphasis. The first area focuses on demonstrating the readiness of FHIR-based Subscriptions for improving interactivity with third-party apps, and the second area focuses on identifying and testing innovative approaches that would inform future changes to the TEFCA infrastructure to increase adoption of Individual Access Service (IAS).
