Extension: Logic definition

Official URL: http://hl7.org/fhir/StructureDefinition/cqf-logicDefinition Version: 5.1.0-cibuild
Standards status: Trial-use Maturity Level: 2 Responsible: HL7 International / Clinical Decision Support Computable Name: LogicDefinition
Other Identifiers: OID:2.16.840.1.113883.4.642.5.1740

Represents a specific logic definition used by the artifact. When logic is referenced from knowledge artifacts, this extension allows each referenced definition to be represented independently so that consumers know which specific expressions are being referenced (i.e. not all expressions in a given library are always used), as well as allows processing applications (such as narrative generation) to easily surface the definitions to provide capabilities such as navigation.

    Complex Extension: Represents a specific logic definition used by the artifact.

    • libraryName: string: The name of the library that contains this definition. This is the library name, not the library alias within any particular library usage, and SHOULD be the fully qualified name of the library (i.e. namespace included).
    • name: string: The name of the definition, e.g. Initial Population. For function definitions, this SHOULD include the function parameters (e.g. "Measure Observation"(Encounter Encounter)).
    • statement: string: The complete declaration statement for the definition. For example, define "Initial Population": [Encounter: "Inpatient"] E where duration in days of E.period > 2.
    • displayCategory: string: A string value providing a display category for the logic definition displayed in any human readable representation.
    • displaySequence: integer: An integer value indicating the order in which this definition should be displayed in any human readable representation.
