FHIR Extensions Pack, published by HL7 International / FHIR Infrastructure. This guide is not an authorized publication; it is the continuous build for version 5.2.0-ballot 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: Logic definition
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.
Context of Use
This extension may be used on the following element(s):

Summary
Complex Extension: 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.
- 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.
Maturity: 2
