V2 to FHIR

Review Note:
The focus of this first HL7 v2-to-FHIR STU Ballot is on an initial set of messages, segments, data types, and vocabulary to establish the foundation on which to expand and cover the full range of HL7 v2 messages in actual use. The purpose is primarily to solicit feedback on the accuracy of the proposed mappings. Secondary is to solicit feedback on structure and navigation. Suggestions on additional messages, segments, data types, and vocabulary to prioritize supporting real-world use are welcome as well and should be marked as A-S in the ballot spreadsheet. Lastly, specific questions are provided [here](questions.html).

The HL7 V2 to FHIR Implementation Guide supports the mapping of HL7 Version 2 messages segments, datatypes and vocabulary to HL7 FHIR Release 4.0 Bundles, Resources, Data Types and Coding Systems.

This implementation guide provides the Concept Maps and references to the Spreadsheets used to generate them, as well as additional information and material to support validation and testing of implementations.

This guide is organized into three main sections:

  1. Introduction
    This section provides an overview of the project, and explains how mapping is performed. You can also find questions to address in this ballot, the glossary and acknowledgements.

  2. Mapping Guidelines
    This section provides the rules and guidelines used to document the mappings such as identification of each HL7 v2 element with a mapping, the conditions under which the HL7 v2 element may map to one or more HL7 FHIR components, as well references to more specific mappings considering context, e.g., when to map PID data to Patient vs. RelatedPerson, or a CWE encoded element to either CodeableConcept, Coding, or code.

  3. Mappings
    This section provides an index to the mappings produced by this project, organized by message, segment,datatype, or vocabulary mapping.

  4. Implementation and Use
    This section covers implementation considerations, validation, and provides example test conversions.

  5. Profiles
    This section provides the profiles for the HL7 FHIR ConceptMap that describes the data maintained in Concept Maps for each of the message, segment, data type, and vocabulary mapping, as well as a profile for HL7 FHIR Bundle that establishes the basic structure/content of a HL7 FHIR message resulting from an HL7 v2 message.
