# Task Definitions

<a id="Task"></a>

## Task
A task to be performed

**Definition:** A task to be performed as a part of a workflow and the related informations like inputs, outputs and execution progress. While very simple workflows can be implemented with [[[Request]]] alone, most workflows would require a Task (explicit or contained) as a means to track the execution progress (i.e. inputs, outputs, status). Please refer to [Fulfillment/Execution](request.html#fulfillment).

**Cardinality:** 0..*

**Constraints:** tsk-0 | error | Last modified date must be greater than or equal to authored-on date. | lastModified.exists().not() or authoredOn.exists().not() or lastModified >= authoredOn; tsk-1 | error | Task.restriction is only allowed if the Task is seeking fulfillment and a focus is specified. | restriction.exists() implies (code.coding.where(code='fulfill' and system='http://hl7.org/fhir/CodeSystem/task-code').exists() and focus.exists() and focus.value.ofType(Reference).exists())

**Mappings:** workflow=Request, Event; rim=ControlAct[moodCode=INT]; w5=workflow.order


<a id="Task.identifier"></a>

## Task.identifier
Task Instance Identifier

**Definition:** The business identifier for this task.

**Cardinality:** 0..*

**Type:** [Identifier](/Identifier)

**Mappings:** workflow=Request.identifier, Event.identifier; w5=FiveWs.identifier; rim=.id


<a id="Task.basedOn"></a>

## Task.basedOn
Request fulfilled by this task

**Definition:** BasedOn refers to a higher-level authorization that triggered the creation of the task.  It references a "request" resource such as a ServiceRequest, MedicationRequest, CarePlan, etc. which is distinct from the "request" resource the task is seeking to fulfill.  This latter resource is referenced by focus.  For example, based on a CarePlan (= basedOn), a task is created to fulfill a ServiceRequest ( = focus ) to collect a specimen from a patient.

**Comments:** Task.basedOn is never the same as Task.focus.  Task.basedOn will typically not be present for 'please fulfill' Tasks as a distinct authorization is rarely needed to request fulfillment.  If the Task is seeking fulfillment of an order, the order to be fulfilled is always communicated using `focus`, never basedOn.  However, authorization may be needed to perform other types of Task actions.  As an example of when both would be present, a Task seeking suspension of a prescription might have a Task.basedOn pointing to the ServiceRequest ordering surgery (which is the driver for suspending the MedicationRequest - which would be the Task.focus).

**Cardinality:** 0..*

**Type:** Reference([Resource](/Resource))

**Summary:** true

**Mappings:** workflow=Request.basedOn, Event.basedOn; rim=.outboundRelationship[typeCode=FLFS].target[moodCode=INT]


<a id="Task.groupIdentifier"></a>

## Task.groupIdentifier
Requisition or grouper id

**Definition:** A shared identifier common to multiple independent Task and Request instances that were activated/authorized more or less simultaneously by a single author.  The presence of the same identifier on each request ties those requests together and may have business ramifications in terms of reporting of results, billing, etc.  E.g. a requisition number shared by a set of lab tests ordered together, or a prescription number shared by all meds ordered at one time.

**Requirements:** Billing and/or reporting can be linked to whether multiple requests were created as a single unit.

**Cardinality:** 0..1

**Type:** [Identifier](/Identifier)

**Summary:** true

**Mappings:** workflow=Request.groupIdentifier; rim=.inboundRelationship[typeCode=COMP].source[moodCode=INT].id


<a id="Task.partOf"></a>

## Task.partOf

**Summary:** true

**Mappings:** workflow=Event.partOf; rim=.inboundRelationship[typeCode=COMP].source[moodCode=INT]


<a id="Task.status"></a>

## Task.status
draft | requested | received | accepted | +

**Definition:** The current status of the task.

**Requirements:** These states enable coordination of task status with off-the-shelf workflow solutions that support automation of tasks.

**Cardinality:** 1..1

**Type:** [code](/code)

**Binding:** required:[task-status](/valueset-task-status)

**Summary:** true

**Is Modifier:** true (Reason: This element is labeled as a modifier because it is a status element that contains status entered-in-error which means that the resource should not be treated as valid)

**Mappings:** workflow=Request.status, Event.status; w5=FiveWs.status; rim=.statusCode


<a id="Task.statusReason"></a>

## Task.statusReason
Reason for current status

**Definition:** An explanation as to why this task is held, failed, was refused, etc.

**Comments:** This applies to the current status.  Look at the history of the task to see reasons for past statuses.

**Cardinality:** 0..*

**Type:** [CodeableReference](/CodeableReference)

**Binding:** example:[task-status-reason](/valueset-task-status-reason)

**Summary:** true

**Mappings:** rim=.inboundRelationship[typeCode=SUBJ].source[classCode=CACT, moodCode=EVN, code="status change"].reasonCode; workflow=Request.statusReason, Event.statusReason


<a id="Task.businessStatus"></a>

## Task.businessStatus
E.g. "Specimen collected", "IV prepped"

**Definition:** Contains business-specific nuances of the business state.

**Requirements:** There's often a need to track substates of a task - this is often variable by specific workflow implementation.

**Cardinality:** 0..1

**Type:** [CodeableConcept](/CodeableConcept)

**Binding:** example:[task-business-status](/valueset-task-business-status)

**Summary:** true

**Mappings:** rim=.inboundRelationship[typeCode=SUBJ].source[classCode=OBS, moodCode=EVN, code="business status"]


<a id="Task.intent"></a>

## Task.intent
unknown | proposal | plan | order | original-order | reflex-order | filler-order | instance-order | option

**Definition:** Indicates the "level" of actionability associated with the Task, i.e. this a proposed task, a planned task, an actionable task, etc.

**Comments:** This element is immutable.  Proposed tasks, planned tasks, etc. must be distinct instances.

In most cases, Tasks will have an intent of "order".

**Cardinality:** 1..1

**Type:** [code](/code)

**Binding:** required:[task-intent](/valueset-task-intent)

**Summary:** true

**Mappings:** workflow=Request.intent; w5=FiveWs.class; rim=.moodCode


<a id="Task.priority"></a>

## Task.priority
routine | urgent | asap | stat

**Definition:** Indicates how quickly the Task should be addressed with respect to other requests.

**Requirements:** Used to identify the service level expected while performing a task.

**Meaning if Missing:** If missing, this task should be performed with normal priority

**Cardinality:** 0..1

**Type:** [code](/code)

**Binding:** required:[request-priority](/valueset-request-priority)

**Mappings:** workflow=Request.priority; w5=FiveWs.grade; rim=.priorityCode


<a id="Task.doNotPerform"></a>

## Task.doNotPerform
True if Task is prohibiting action

**Definition:** If true indicates that the Task is asking for the specified action to *not* occur.

**Comments:** The attributes provided with the Task qualify what is not to be done. For example, if a requestedPeriod is provided, the 'do not' request only applies within the specified time. If a requestedPerformer is specified then the 'do not' request only applies to performers of that type. Qualifiers include: code, subject, occurrence, requestedPerformer and performer.

In some cases, the Request.code may pre-coordinate prohibition into the requested action. E.g. 'NPO' (nothing by mouth), 'DNR' (do not resuscitate). If this happens, doNotPerform SHALL NOT be set to true. I.e. The resource SHALL NOT have double negation. (E.g. 'Do not DNR').

When Task.focus refers to a Request Resource, it is that Request's doNotPerform Flag that indicates that the action should not be performed. A Task can be used to request that authorized action is not performed by having task.focus point to that request resource and use Task.code as the do not perform indicator.

Note that the use of doNotPerform and negation in Task.code can cause ambiguity and the impact of this should be considered not only for task but also for all related resources.

**Cardinality:** 0..1

**Type:** [boolean](/boolean)

**Summary:** true

**Is Modifier:** true (Reason: If true, this element negates the Task. For example, instead of a request to perform a task, it is a request _not_ to perform a task.)

**Mappings:** workflow=Request.doNotPerform, Event.doNotPerform; w5=FiveWs.what[x]; rim=.code

<a id="Task.focus"></a>

## Task.focus
What task is acting on

**Definition:** The request being fulfilled or the resource being manipulated (changed, suspended, etc.) by this task.

**Comments:** If multiple resources need to be manipulated, use sub-tasks.  (This ensures that status can be tracked independently for each referenced resource.). Typically a Task should only have one focus.  If multiple focuses are provided, then action must be taken on the complete set as a whole (i.e,. all must be accepted, rejected, cancelled, held, completed, etc. as a whole). If there is a possibility to have different statuses for different focuses, then there SHALL be a separate Task instance for each focus.

**Requirements:** Used to identify the thing to be done.

**Conditions:** tsk-1

**Definition:** Principal physical location where this task is performed.

**Comments:** This should only be specified when the Task to be/being performed happens or is expected to happen primarily within the bounds of a single Location.  Other locations (e.g. source, destination, etc.) would either be reflected on the 'basedOn' Request or be conveyed as distinct Task.input values.

**Comments:** This will typically not be present for Tasks with a code of 'please fulfill' as, for those, the reason for action is conveyed on the Request pointed to by Task.focus.  Some types of tasks will not need a 'reason'.  E.g. a request to discharge a patient can be inferred to be 'because the patient is ready' and this would not need a reason to be stated on the Task.

**Cardinality:** 0..*

**Mappings:** workflow=Request.note, Event.note; rim=.inboundRelationship[typeCode=SUBJ, ].source[classCode=OBS, moodCode=EVN, code="annotation"].value(string)


<a id="Task.relevantHistory"></a>

## Task.relevantHistory
Key events in history of the Task

**Definition:** Links to Provenance records for past versions of this Task that identify key state transitions or updates that are likely to be relevant to a user looking at the current version of the task.

**Comments:** This element does not point to the Provenance associated with the *current* version of the resource - as it would be created after this version existed.  The Provenance for the current version can be retrieved with a _revinclude.

**Mappings:** workflow=Request.relevantHistory; rim=.inboundRelationship(typeCode=SUBJ].source[classCode=CACT, moodCode=EVN]


<a id="Task.restriction"></a>

## Task.restriction
Constraints on fulfillment tasks

**Definition:** If the Task.focus is a request resource and the task is seeking fulfillment (i.e. is asking for the request to be actioned), this element identifies any limitations on what parts of the referenced request should be actioned.

**Comments:** This element should only be used when the Task is seeking fulfillment of a request resource that authorizes a broader set of subjects, repetitions and/or time-period than the Task itself is seeking execution against.  It is not used otherwise.

**Requirements:** Sometimes when fulfillment is sought, you don't want full fulfillment.

**Conditions:** tsk-1

**Cardinality:** 0..1

**Type:** [BackboneElement](/BackboneElement)

**Mappings:** rim=Instead of pointing to request, would point to component of request, having these characteristics


<a id="Task.restriction.repetitions"></a>

## Task.restriction.repetitions

**Definition:** Indicates the number of times the requested action should occur.

**Requirements:** E.g. order that requests monthly lab tests, fulfillment is sought for 1.

**Cardinality:** 0..1

**Type:** [positiveInt](/positiveInt)

**Mappings:** rim=.repeatNumber


<a id="Task.restriction.period"></a>

## Task.restriction.period
When fulfillment is sought

**Definition:** The time-period for which fulfillment is sought. This must fall within the overall time period authorized in the referenced request.  E.g. ServiceRequest.occurance[x].

**Comments:** This is distinct from Task.executionPeriod. ExecutionPeriod indicates when the task needs to be initiated, while Task.restriction.period specifies the subset of the overall authorization that this period covers. For example, a MedicationRequest with an overall effective period of 1 year might have a Task whose restriction.period is 2 months (i.e. satisfy 2 months of medication therapy), while the execution period might be 'between now and 5 days from now' - i.e. If you say yes to this, then you're agreeing to supply medication for that 2 month period within the next 5 days.

Note that period.high is the due date representing the time by which the task should be completed.

**Requirements:** E.g. order that authorizes 1 year's services.  Fulfillment is sought for next 3 months.

**Cardinality:** 0..1

**Type:** [Period](/Period)

**Mappings:** rim=.effectiveTime(IVL<TS>)


<a id="Task.restriction.recipient"></a>

## Task.restriction.recipient
Individual or entity from whom fulfillment is being sought

**Definition:** For requests directed at multiple potential recipients or targets, this is used to specify the individual or entity from whom fulfillment is being sought.

**Comments:** If seeking fulfillment of a ServiceRequest where the ServiceRequest.subject was a Group of devices, but the Task was only seeking execution against a single device. If just creating a Task that is to manipulate a device in the absence of a broader order, there's no need for restriction.recipient.  The Device to be manipulated would be the Task.focus (and potentially the Task.for - if the action wasn't for the benefit of a Patient or some other record).
