FHIR Extensions Pack
5.3.0-ballot-tc1 - (September 2025 Ballot) International flag

FHIR Extensions Pack, published by HL7 International / FHIR Infrastructure. This guide is not an authorized publication; it is the continuous build for version 5.3.0-ballot-tc1 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/fhir-extensions/ and changes regularly. See the Directory of published versions

Extension: Supporting Evidence

Official URL: http://hl7.org/fhir/StructureDefinition/cqf-supportingEvidence Version: 5.3.0-ballot-tc1
Standards status: Draft Maturity Level: 1 Responsible: HL7 International / Clinical Decision Support Computable Name: SupportingEvidence

Specifies the result of a supporting evidence expression in the measure population. The result of the expression is represented in an extension, using the same mapping as specified in Using CQL With FHIR, with the exception that tuples and lists are represented in extensions, rather than mapped to the Parameters resource.

This is an draft extension definition; the committee is seeking implementation feedback, and the definition or contents of the extension may change in future versions

Context of Use

This extension may be used on the following element(s)

    Summary

    Complex Extension: Specifies the result of a supporting evidence expression in the measure population. The result of the expression is represented in an extension, using the same mapping as specified in Using CQL With FHIR, with the exception that tuples and lists are represented in extensions, rather than mapped to the Parameters resource.

    • name: code: This corresponds to the name element of the supporting evidence definition
    • description: string: This corresponds to the description element of the supporting element definition
    • code: CodeableConcept: This corresponds to the cqf-expressionCode extension of the supporting evidence definition.
    • value: base64Binary, boolean, canonical, code, date, dateTime, decimal, id, instant, integer, integer64, markdown, oid, positiveInt, string, time, unsignedInt, uri, url, uuid, Address, Age, Annotation, Attachment, CodeableConcept, CodeableReference, Coding, ContactPoint, Count, Distance, Duration, HumanName, Identifier, Money, Period, Quantity, Range, Ratio, RatioRange, Reference, SampledData, Signature, Timing, ContactDetail, DataRequirement, Expression, ParameterDefinition, RelatedArtifact, TriggerDefinition, UsageContext, Availability, ExtendedContactDetail, Dosage, Meta: The result of evaluating the supporting evidence definition, mapped to extension space as specified in Using CQL With FHIR, with the exception that extensions are used as the primary value container, rather than a Parameters resource.
