## Resource Profile: QICore Task Done

Official URL: http://hl7.org/fhir/us/qicore/StructureDefinition/qicore-taskdone | Version: 7.0.2
Standards status: Trial-use | Maturity Level: 4 | Computable Name: QICoreTaskDone

Positive profile of Task for decision support/quality metrics. Indicates a task that with a positive status

"Must Have", "QI Elements" and "primary code path" are defined in the QI-Core Must Support section.
QI Elements:

- basedOn: (QI) Request fulfilled by this task
- executionPeriod: (QI) Start and end time of execution
- focus: (QI) What task is acting on
- intent: (QI) unknown | proposal | plan | order | original-order | reflex-order | filler-order | instance
- code: (QI) Task Type
- status: (QI) draft​ | requested​ | received​ | accepted​ | ready | in-progress​ | on-hold​ | completed
- encounter: (QI) Healthcare event during which this task originated
- for: (QI) Beneficiary of the Task
- priority: (QI) routine | urgent | asap | stat

Primary code path: code
(PCPath) This element is the primary code path for this resource CQL Retrieve
Usage

The Task profile defines the conformance expectations for a Task, regardless of whether it is a positive or negative statement. The TaskDone and TaskRejected profiles represent the positive and negative statements for a task.

See the patterns page for implementation and usage patterns.
