Data Segmentation for Privacy (DS4P) Pilot - SATVA

The SATVA DS4P Pilot Project for Ultra-Sensitive Privacy Disclosure (USPD) developed, tested, piloted standards-based interoperability for data in transit. SATVA methods function for both HIE and NwHIN Direct interoperability. The SATVA implementation demonstrated compliance with all 42 CFR Part 2 requirements as an example of a specific but extensible class approach to management of all ultra-sensitive disclosures. Electronic data exchange supported C32/CCDA records as well as non-structured payloads such as PDF. Testing demonstrated interoperability between “foreign” (e.g., different software vendors) EHRs via NHIN Direct.
