0. Task
Definition | A task to be performed.
Short | A task to be performed
Control | 0..*
Is Modifier | false
Must Support | false
Summary | false
Invariants | dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources (contained.contained.empty()) dom-3: If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource (contained.where((('#'+id in (%resource.descendants().reference | %resource.descendants().ofType(canonical) | %resource.descendants().ofType(uri) | %resource.descendants().ofType(url))) or descendants().where(reference = '#').exists() or descendants().where(ofType(canonical) = '#').exists() or descendants().where(ofType(canonical) = '#').exists()).not()).trace('unmatched', id).empty()) dom-4: If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated (contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()) dom-5: If a resource is contained in another resource, it SHALL NOT have a security label (contained.meta.security.empty()) dom-6: A resource should have narrative for robust management (text.`div`.exists()) inv-1: 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: 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())
2. Task.implicitRules
Definition | A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.
Short | A set of rules under which this content was created
Comments | Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of its narrative along with other profiles, value sets, etc.
Control | 0..1
Type | uri
Is Modifier | true because This element is labeled as a modifier because the implicit rules may provide additional knowledge about the resource that modifies its meaning or interpretation
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Must Support | false
Summary | true
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
4. Task.contained
Definition | These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, nor can they have their own independent transaction scope. This is allowed to be a Parameters resource if and only if it is referenced by a resource that provides context/meaning.
Short | Resources, according to 'input', used in PhPID generation.Contained, inline Resources
Comments | This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags in their meta elements, but SHALL NOT have security labels.
Control | 40..* This element is affected by the following invariants: dom-2, dom-4, dom-3, dom-5
Type | Resource
Is Modifier | false
Must Support | false
Summary | false
Alternate Names | inline resources, anonymous resources, contained resources
6. Task.modifierExtension
Definition | May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
Short | Extensions that cannot be ignored
Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
Control | 0..*
Type | Extension
Is Modifier | true because Modifier extensions are expected to modify the meaning or interpretation of the resource that contains them
Must Support | false
Summary | true
Requirements | Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.
Alternate Names | extensions, user content
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists())
8. Task.identifier

Short | Identifier assigned by the requestor to track the request.Task Instance Identifier
Note | This is a business identifier, not a resource identifier (see discussion)
Control | 0..*
Type | Identifier
Is Modifier | false
Must Support | false
Summary | false
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))

Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
12. Task.status
Definition | The current status of the task.
Short | Status of the task should always be 'requested' when a new requestdraft | requested | received | accepted | +
Control | 1..1
Binding | The codes SHALL be taken from Request Status Value Set http://hl7.org/fhir/ValueSet/task-status|5.0.0 (required to `http://who-umc.org/idmp/ValueSet/requestStatus` )
Type | code
Is Modifier | true because 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
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Must Support | false
Summary | true
Requirements | These states enable coordination of task status with off-the-shelf workflow solutions that support automation of tasks.
Pattern Value | `requested`
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
14. Task.businessStatus
Definition | Contains business-specific nuances of the business state.
Short | business-specific stateE.g. "Specimen collected", "IV prepped"
Control | 0..1
Binding | The domain-specific business-contextual sub-state of the task. For example: "Blood drawn", "IV inserted", "Awaiting physician signature", etc.
Type | CodeableConcept
Is Modifier | false
Must Support | false
Summary | true
Requirements | There's often a need to track substates of a task - this is often variable by specific workflow implementation.
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
16. Task.intent
Definition | Indicates the "level" of actionability associated with the Task, i.e. i+R[9]Cs this a proposed task, a planned task, an actionable task, etc.
Short | unknown | proposal | plan | order | original-order | reflex-order | filler-order | instance-order | option
Comments | This element is immutable. Proposed tasks, planned tasks, etc. must be distinct instances. In most cases, Tasks will have an intent of "order".
Control | 1..1
Binding | The codes SHALL be taken from TaskIntent http://hl7.org/fhir/ValueSet/task-intent|5.0.0 (required to `http://hl7.org/fhir/ValueSet/task-intent|5.0.0` ) Distinguishes whether the task is a proposal, plan or full order.
Type | code
Is Modifier | false
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Must Support | false
Summary | true
Pattern Value | `proposal`
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
18. Task.priority
Definition | Indicates how quickly the Task should be addressed with respect to other requests.
Short | Task priorityroutine | urgent | asap | stat
Control | 0..1
Binding | The codes SHALL be taken from RequestPriority http://hl7.org/fhir/ValueSet/request-priority|5.0.0 (required to `http://hl7.org/fhir/ValueSet/request-priority|5.0.0` ) The priority of a task (may affect service level applied to the task).
Type | code
Is Modifier | false
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Must Support | false
Summary | false
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
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
20. Task.doNotPerform
Definition | If true indicates that the Task is asking for the specified action to not occur.
Short | True if Task is prohibiting action
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 recussitate). If this happens, doNotPerform SHALL NOT be set to true. I.e. The resource shall not have double negation. (E.g. 'Do not DNR'). doNotPerform should ONLY be used with Tasks that are tightly bounded in time or process phase. E.g. 'Do not fulfill the midnight dose of medication X tonight due to the early morning scheduled procedure, where the nurse could reasonably check off 'Med X not given at midnight as instructed'. Similarly, a decision support proposal that a patient should not be given a standard intake questionnaire (because the patient is cognitively impaired) would be marked as 'complete' or 'rejected' when the clinician preps the CarePlan or order set after reviewing the decision support results. If there is a need to create a standing order to not do something that can't be satisfied by a single 'non-action', but rather an ongoing refusal to perform the function, MedicationRequest, ServiceRequest or some other form of authorization should be used.
Control | 0..1
Type | boolean
Is Modifier | true because 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.
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Must Support | false
Summary | true
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
22. Task.code

34. Task.restriction
Definition | Not used in this profile 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.
Short | Not used in this profileConstraints on fulfillment tasks
Comments | Task.restriction can only be present if the Task is seeking fulfillment of another Request resource, and the restriction identifies what subset of the authorization conveyed by the request is supposed to be fulfilled by this Task. A possible example could be a standing order (the request) covering a significant time period and/or individuals, while the Task seeks fulfillment for only a subset of that time-period and a single individual.

Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
Short | Extensions that cannot be ignored even if unrecognized
Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

2. Task.id
Definition | The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.
Short | Logical id of this artifact
Comments | Within the context of the FHIR RESTful interactions, the resource has an id except for cases like the create and conditional update. Otherwise, the use of the resouce id depends on the given use case.

6. Task.implicitRules
Definition | A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.
Short | A set of rules under which this content was created
Comments | Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of its narrative along with other profiles, value sets, etc.

8. Task.language
Definition | The base language in which the resource is written.
Short | Language of the resource content
Comments | Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).

10. Task.text
Definition | A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety.
Short | Text summary of the resource, for human interpretation
Comments | Contained resources do not have a narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later.

Invariants | ele-1: All FHIR elements must have a @value or children (`hasValue() or (children().count() > id.count())`)
12. Task.contained
Definition | These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, nor can they have their own independent transaction scope. This is allowed to be a Parameters resource if and only if it is referenced by a resource that provides context/meaning.
Short | Resources, according to 'input', used in PhPID generation.
Comments | This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags in their meta elements, but SHALL NOT have security labels.

Invariants | ele-1: All FHIR elements must have a @value or children (`hasValue() or (children().count() > id.count())`)
24. Task.basedOn
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.
Short | Request fulfilled by this task
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).

26. Task.groupIdentifier
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.
Short | Requisition or grouper id
Control | 0..1

Is Modifier | false
Must Support | false
Summary | true
Requirements | Billing and/or reporting can be linked to whether multiple requests were created as a single unit.
Invariants | ele-1: All FHIR elements must have a @value or children (`hasValue() or (children().count() > id.count())`)
28. Task.partOf

Short | Composite task
Comments | This should usually be 0..1.
Control | 0..*
Type | Reference(Task)
Is Modifier | false

Requirements | Allows tasks to be broken down into sub-steps (and this division can occur independent of the original task).
Invariants | ele-1: All FHIR elements must have a @value or children (`hasValue() or (children().count() > id.count())`)
30. Task.status
Definition | The current status of the task.
Short | Status of the task should always be 'requested' when a new request
Control | 1..1
Binding | The codes SHALL be taken from Request Status Value Set (required to `http://who-umc.org/idmp/ValueSet/requestStatus` )
Type | code

Invariants | ele-1: All FHIR elements must have a @value or children (`hasValue() or (children().count() > id.count())`)
40. Task.doNotPerform
Definition | If true indicates that the Task is asking for the specified action to not occur.
Short | True if Task is prohibiting action
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 recussitate). If this happens, doNotPerform SHALL NOT be set to true. I.e. The resource shall not have double negation. (E.g. 'Do not DNR'). doNotPerform should ONLY be used with Tasks that are tightly bounded in time or process phase. E.g. 'Do not fulfill the midnight dose of medication X tonight due to the early morning scheduled procedure, where the nurse could reasonably check off 'Med X not given at midnight as instructed'. Similarly, a decision support proposal that a patient should not be given a standard intake questionnaire (because the patient is cognitively impaired) would be marked as 'complete' or 'rejected' when the clinician preps the CarePlan or order set after reviewing the decision support results. If there is a need to create a standing order to not do something that can't be satisfied by a single 'non-action', but rather an ongoing refusal to perform the function, MedicationRequest, ServiceRequest or some other form of authorization should be used.

Short | When fulfillment is sought
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.

Definition | May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
Short | Extensions that cannot be ignored even if unrecognized
Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
