Task

KT2_Task (Task)	I		Task	Element id Task Short description A task to be performed Definition An eHealth activity assigned to a patient. Data type Task Constraints 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().as(canonical) \| %resource.descendants().as(uri) \| %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(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` Mappings rim: Entity. Role, or Act workflow: Request, Event rim: ControlAct[moodCode=INT]
id	Σ	0..1	string	There are no (further) constraints on this element Element id Task.id Short description Logical id of this artifact Definition The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes. Comments The only time that a resource does not have an id is when it is being submitted to the server using a create operation. Data type string
meta	Σ	0..1	Meta	There are no (further) constraints on this element Element id Task.meta Short description Metadata about the resource Definition The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource. Data type Meta Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())`
implicitRules	Σ ?!	0..1	uri	There are no (further) constraints on this element Element id Task.implicitRules Short description A set of rules under which this content was created 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. 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 it's narrative along with other profiles, value sets, etc. Data type uri Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())`
language		0..1	codeBinding	There are no (further) constraints on this element Element id Task.language Short description Language of the resource content Definition The base language in which the resource is written. 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). Data type code Binding A human language. CommonLanguages (preferred) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())`
text		0..1	Narrative	There are no (further) constraints on this element Element id Task.text Short description Text summary of the resource, for human interpretation Alternate names narrative, html, xhtml, display 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. Comments Contained resources do not have 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. Data type Narrative Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: Act.text?
contained		0..*	Resource	There are no (further) constraints on this element Element id Task.contained Short description Contained, inline Resources Alternate names inline resources, anonymous resources, contained resources Definition These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope. 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. Data type Resource Mappings rim: N/A
extension	I	0..*	Extension	Element id Task.extension Short description Additional content defined by implementations Alternate names extensions, user content Definition May be used to represent additional information that is not part of the basic definition of the resource. To make the use of extensions safe and manageable, 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. 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. Data type Extension Sliced: Unordered, Open, by url(Value) Constraints 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()` Mappings rim: N/A
resource-origin	I	0..1	Extension(Reference(KT2_Device))	Element id Task.extension:resource-origin Short description Optional Extensions Element Alternate names extensions, user content Definition Defines the author of the resource. Comments Part of the authorisation model. Upon creation of the resource this extension is set to the device that created it. Data type Extension(Reference(KT2_Device)) Extension URL http://koppeltaal.nl/fhir/StructureDefinition/resource-origin Constraints 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()` Mappings rim: N/A rim: n/a

Comments Use this extension to refer to the ActivityDefinition it instantiates. Data type Extension(Reference(KT2_ActivityDefinition)) Extension URL http://vzvz.nl/fhir/StructureDefinition/instantiates Constraints 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()` Mappings rim: N/A rim: n/a
modifierExtension	?! I	0..*	Extension	There are no (further) constraints on this element Element id Task.modifierExtension Short description Extensions that cannot be ignored Alternate names extensions, user content 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 manageable, 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). 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. 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. Data type Extension Constraints 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()` Mappings rim: N/A

basedOn	Σ	0..0	Reference(Resource)	There are no (further) constraints on this element Element id Task.basedOn Short description 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, ServiceRequest, CarePlan, etc. which is distinct from the "request" resource the task is seeking to fulfill. This latter resource is referenced by FocusOn. For example, based on a ServiceRequest (= BasedOn), a task is created to fulfill a procedureRequest ( = FocusOn ) to collect a specimen from a patient.

Reference to ActivityDefinition

⚠️ Warning As of 2023-11-02 the way the ActivityDefinition is referenced is changed!

A Task should refer to the ActivityDefinition it instantiates. This provides the possibility to search for Tasks that instantiate a specific instance of an ActivityDefinition, which in turn can be found based on its publisherId.

Using the element instantiatesCanonical does not however allow chaining of the search parameters. Therefore this profile contains an extension instantiates which should hold the reference to the instantiated ActivityDefinition.

The element instantiatesCanonical should not be used for this reference. Receivers of a Task instance can ignore any value in the instantiatesCanonical and should look for the referred ActivityDefinition in the instantiates extension.

KT2_Task.owner

KT2_Task.owner determines which actor is the executor of the respective task.

The RelatedPerson can be assigned as the owner of a task either directly or through a CareTeam.

KT2_Task.partOf

This element is used to indicate the reference of a subtask to the main task. The main task is assigned to the patient through KT2_Task.owner= Reference (KT2_Patient). The subtask is created as follows:

KT2_Task.partOf` references the main task
The KT2_RelatedPerson who assists becomes the Task.owner
KT2_Task.forreferences thePatient` of the main task

KT2_Task.code

With the KT2_Task.code element the permission of a KT2_Task can be set to view. The exact meaning of the view permission can differ per application because authorisations in Koppeltaal 2.0 are defined and executed by the applications.

Example

This example shows a subtask for the RelatedPerson assigned in the Task of the patient.
