Resource Profile: US Quality Core Task Rejected

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

Profile of TaskRejected 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) The potential performer who claimed ownership of the task has decided not to execute it prior to performing any action
  • statusReason: (USCDI+ Quality)
  • code: (USCDI+ Quality) Task Type
  • focus: (USCDI+ Quality)
  • executionPeriod: (USCDI+ Quality) The timing the task was rejected and the reason.
  • reasonCode: (USCDI+ Quality) Why task is needed

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

Profile Specific Implementation Guidance

This profile represents a task that was rejected before execution. To represent tasks that were not rejected, use the US Quality Core Task profile.
