R4 Ballot #2 (Mixed Normative/Trial use)

This page is part of the FHIR Specification (v3.5.0: R4 Ballot #2). The current version which supercedes this version is 5.0.0. For a full list of available versions, see the Directory of published versions . Page versions: R5 R4B R4 R3

Normative Candidate Note: Some of the content on this page (marked clearly) is candidate normative content for R4 in the Infrastructure Package. Once normative, it will lose it's Maturity Level, and breaking changes will no longer be made.

This page describes a set of types used for conveying metadata about knowledge resources (mainly for Terminology, Conformance and Clinical Definition resources).

A DataRequirement differs from a parameter in that it specifies the data to be provided in terms of the type of data, and specific filters on code-valued and/or date-valued attributes. Data requirements are not named because they are referenced by type within the evaluation context.

DataRequirements are used by knowledge modules to communicate the set of required data to a consumer in a way that is computable (as opposed to a set of named parameters which must be integrated by hand based on the meaning of the parameter as communicated through the documentation).

DataRequirements are typically used to communicate patient-dependent information such as MedicationStatements and Encounters, whereas Parameters are typically used to communicate patient-independent information such as configuration values.

For example, consider the following CQL expression:

define "Total Colectomy Procedures":
  [Procedure: "Total Colectomy Value Set"] P
    where P.performedPeriod during "Measurement Period"

The criteria is looking for procedures matching the "Total Colectomy Value Set" that were performed during the "Measurement Period". In this case, "Measurement Period" is a parameter, referenced by name, whereas the reference to Procedure uses the name of the resource type, and so constitutes a data requirement of the criteria:

<dataRequirement>
	<type value="Procedure"/>
	<codeFilter>
		<path value="code"/>
		<valueSetString value="Total Colectomy Value Set"/>
	</codeFilter>
	<dateFilter>
		<path value="performedPeriod"/>
		<valuePeriod>
			<start value="2016-01-01"/>
			<end value="2016-12-31"/>
		</valuePeriod>
	</dateFilter>
</dataRequirement>

If a resource type has multiple date attributes, then it may be necessary to include multiple date criteria. For instance, in the example above the Procedure resource is using the performedPeriod date attribute. However, the Procedure resource also provides a performedDateTime (specific date and/or time when procedure was performed) attribute. Therefore, if the date criteria for the Procedure in the example was recorded using the performedDateTime attribute, the date criteria would be incomplete. To account for this additional date attribute, the example could be expanded as follows:

define "Total Colectomy Procedures":
  [Procedure: "Total Colectomy Value Set"] P
    where exists (P.performedPeriod during "Measurement Period")
	  or exists (P.performedDateTime during "Measurement Period")

The data requirement for the expanded criteria:

<dataRequirement>
	<type value="Procedure"/>
	<codeFilter>
		<path value="code"/>
		<valueSetString value="Total Colectomy Value Set"/>
	</codeFilter>
	<dateFilter>
		<path value="performedPeriod"/>
		<path value="performedDateTime"/>
	</dateFilter>
</dataRequirement>

DataRequirement is used in the following places: TriggerDefinition, GuidanceResponse, Library and PlanDefinition

The ParameterDefinition structure defines a parameter to a knowledge asset such as a decision support rule or quality measure.

Parameters are typically used to communicate patient-independent information such as configuration values, whereas DataRequirements are typically used to communicate patient-dependent information such as MedicationStatements and Encounters.

The TriggerDefinition structure defines when a knowledge artifact is expected to be evaluated. The structure can represent three main kinds of triggering events, depending on the value of type:

  • Named Event
  • Scheduled Event
  • Data Event

A named event is an event identified by the implementation environment. This allows any event generated within the implementation environment to be used as a trigger, but it requires pre-coordination of the names involved with the consuming environments. HL7 v2 events are assigned the URI http://terminology.hl7.org/CodeSystem/v2-0003#[code] e.g. http://terminology.hl7.org/CodeSystem/v2-0003/A01, and reference any data change that would trigger the sending of the matching HL7 v2 version, if the application providing the FHIR API supports v2 events internally.

A scheduled event occurs on a fixed or periodic schedule.

And finally, a data event occurs in response to some data-related event in the integrated environment such as a record being added or updated. The data-of-interest for a data event is described using a DataRequirement. This allows for systems to automatically invoke based on data activity occurring within the system. A condition may also be specified to further refine the trigger
