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

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

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

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

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
