Health Level Seven (HL7) Cross Paradigm Implementation Guide

This Project represents a significant next step in the path toward meaningful interoperability as it relates to clear mapping of industry-exchange standards.  This is an extension of the previously successful HL7 Service Oriented Architecture (SOA) Cross Paradigm Interoperability Implementation Guide (IG) for Immunization. 

The project team – pulling together clinicians and technical experts from VHA, SAMHSA, ONC, and CMS as part of the electronic Long Term Services and Support (eLTSS)  Project – is creating artifacts to be used by federal agencies and the larger HL7 community to provide precise, unambiguous mappings between of any two different industry-exchange standards (e.g., CCDA, FHIR, HL7 v.2, and CIMI), supporting the interchange and data transformation between those expression formats.  Non-industry standard formats will be considered for Use Cases in the future.

This project – an expansion of the Immunization IG – will address a much broader set of Use Cases by providing more mappings across different clinical and administrative domains; further, it will also include new versions of the standards. 

The VHA Standards Incubator provides traceability and gap analysis reports for the Use Cases and also addresses values in the data elements for a more complete assessment of information exchange. 

Finally, the project team will develop and transform test messages to further substantiate the validity of the mappings.
