Summary

Complex Extension: Defines a logic definition used by the measure.

  • 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.
  • displaySequence: integer: An integer value indicating the order in which this definition should be displayed in any human readable representation.
  • description: string: Description of the logic definition
