## 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 2026-05-15 | *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. 

**Usage**
  See the [patterns](patterns.md) page for implementation and usage patterns.  

The Task and TaskRejected profiles represent the positive and negative statements for a task.

### Examples

 

| | |
| :--- | :--- |
| [Task rejected using a value set to indicate what was not done](Task-negation-example.md) | Medication reconciliation not done due to patient declination; indicates that none of the tasks in the given not done value set were performed. |
| [Task rejected using a code to indicate what was not done](Task-negation-with-code-example.md) | Medication reconciliation not done due to patient declination; indicates that the specific task, by code, was not done. |

 

For a more complete discussion of representation of negation within USQualityCore and quality improvement artifacts, see the [Negation in US Quality Core](general-requirements.md#negation-in-us-quality-core) topic.

**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

**Usages:**

* Examples for this Profile: [Task/negation-example](Task-negation-example.md) and [Task/negation-with-code-example](Task-negation-with-code-example.md)
