## Resource Profile: US Quality Core Task Rejected

Official URL: http://fhir.org/guides/astp/us-quality-core/StructureDefinition/us-quality-core-taskrejected | Version: 0.1.0
Active as of 2021-06-23 | 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 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 | 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 | 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 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
- code.extension:notDoneValueSet: (USCDI+ Quality) Url of a value set of activities not requested or performed
- 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 and Task/negation-with-code-example
