  1. WEDNESDAY, 2:30–2:50PM Ensuring Conformance& Interoperability NHIN Testing Leslie Power, NHIN Testing Lead (Contractor) Office of the National Coordinator for Health IT

  2. What is the NHIN? A set of policies, standardsand services that enable the Internet to be used for secure and meaningful exchange of health information to improve health and health care. HIMSS 2010

  3. NHIN Specifications Transaction Profiles Utilize exchange patterns for specific transactions In pilot Discovery and Information Exchange Services Rely on foundations to enable exchange patterns Patient Discovery Query & Retrieve Docs HIEM Services Registry Messaging, Security, & Privacy Foundations Enable private, secure, and interoperable communication of health information Messaging Platform Authorization Framework HIMSS 2010

  4. How to Approach Testing the NHIN Specs • Within the network, two concerns must be realized: • that each participating system conforms to the applicable NHIN specifications, and • that each participating system can interact with the others • Conformance does not guarantee interoperability, so we include two testing components: • Conformance Testing • Interoperability Testing HIMSS 2010

  5. Testing Process NISTConformanceTools NHIN Interoperability Testing Lab (Internet Employing CA/UDDI) 1 2 Candidate System HIMSS 2010

  6. Conformance Testing Tools • Focused on validating a single system to single standards • To test conformance to the NHIN specifications • Downloadable testing tools that can be used during development • Self-service via web • Tools keep result log, accessible via URI • Candidates enter success URI on conformance results form, submit form for validation • NIST tools HIMSS 2010

  7. Conformance Testing HIMSS 2010

  8. Web-based HIMSS 2010

  9. Results HIMSS 2010

  10. Interoperability Testing Tools • To test a candidate’s ability to perform common business activities with other NHIN gateways • Testing based on scenarios – threading together individual test cases in basic business interactions • Replicates common NHIN interactions • Records candidate’s results • Self-serve testing HIMSS 2010

  11. Architecture of the Interoperability Lab HIMSS 2010

  12. Candidate Setup Screen HIMSS 2010

  13. Reviewing Progress HIMSS 2010

  14. Reviewing Results HIMSS 2010

  15. NHIN Validation Testing supports validation • Testing ensures that potential participants in NHIN exchange operate in a way that conforms with NHIN specifications • Conformance Testing • Interoperability Testing • Validation confirms testing results and is an input to consideration for approval for NHIN participation HIMSS 2010
