Interoperability Testing Platform

The Sequoia Project has built a robust and rigorous testing platform. The Sequoia Project Interoperability Testing Platform (ITP) is a set of more than a dozen testing tools covering transport, security, and content aspects to improve health information exchange nationwide. While the ITP is available to members and non-members alike, The Sequoia Project members receive exclusive discounts.

Content Testing

Data exchange is just the beginning for successful health data sharing. We are also committed to ensuring the content of those data exchanges is both accurate and useful to providers and patients.

Industry-wide pain points to quality and accurate data content include: 

  • Optionality: More than one way to do things and inconsistent implementation across vendors
  • Terminology: Inconsistent terminology usage
  • Specification ambiguity: Narrowed and clarified specifications are needed
  • Complexity: The C-CDA standard is difficult to understand and consume, and is lacking in clearly documented examples

The Sequoia Project has worked with IHE International to build a robust content testing platform which focuses on known interoperability issues and security. Leveraging Art Decor/ Gazelle Objects Checker, the customized The Sequoia Project Interoperability Testing Platform was piloted in April 2016 and is ISO 17025 Compliant for Conformity Assessment. The tool covers HITSP C32/CCD, HL7 C-CDA CCD R1.1, and R2.1 versions and associated companion guides for Meaningful Use. 

Sequoia Project members enjoy free access ($3,000 value) to the content testing tools.
