2026 US Quality Core Implementation Guide
0.5.0 - release United States of America flag

This page is part of the US Quality Core (v0.5.0: Release) based on FHIR (HL7® FHIR® Standard) R4. This is the current published version in its permanent home (it will always be available at this URL). For a full list of available versions, see the Directory of published versions

Resource Profile: US Quality Core Task

Official URL: http://fhir.org/guides/onc/us-quality-core/StructureDefinition/us-quality-core-task Version: 0.5.0
Active as of 2026-06-05 Computable Name: USQualityCoreTask

Profile of Task for decision support/quality metrics. Defines the core set of elements and extensions for quality rule and measure authors.

USCDI+ Quality Element Support Expectations

Systems are expected to support this profile as part of implementing USCDI+ Quality V1 in FHIR and meeting the conformance requirements of this guide.

The following elements are specifically relevant to USCDI+ Quality V1 data classes and elements. Systems are expected to support these elements as applicable to their role in US Quality Core data exchange. See the Must Support section of this guide for more information. These elements are tagged as (USCDI+ Quality) in the formal profile views.

USCDI+ Quality Elements:

  • basedOn: (USCDI+ Quality) Request fulfilled by this task
  • status: (USCDI+ Quality) draft​ | requested​ | received​ | accepted​ | ready​ | cancelled​ | in-progress​ | on-hold​ | failed​ | completed | entered-in-error
  • statusReason: (USCDI+ Quality) Reason for current status
  • code: (USCDI+ Quality) Task Type
  • focus: (USCDI+ Quality) What task is acting on
  • executionPeriod: (USCDI+ Quality)
  • reasonCode: (USCDI+ Quality)

The Formal Views section also provides the formal summary, definitions, terminology requirements, and mandatory element requirements.
