# US Quality Core Task - 2026 US Quality Core Implementation Guide v0.5.0

## Resource Profile: US Quality Core Task 

 
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](must-support.md) 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](#profile) section also provides the formal summary, definitions, terminology requirements, and mandatory element requirements.

### Profile Specific Implementation Guidance

To represent that a task was rejected before execution, use the [US Quality Core Task Rejected](StructureDefinition-us-quality-core-taskrejected.md) profile.

**Usages:**

* Examples for this Profile: [Task/example](Task-example.md)
* CapabilityStatements using this Profile: [US Quality Core Client CapabilityStatement](CapabilityStatement-us-quality-core-client.md) and [US Quality Core Server CapabilityStatement](CapabilityStatement-us-quality-core-server.md)
