In the SFM Basis context, the national systems Reseptformidleren and Kjernejorunal may be polled for a list of patients having changes:
Reseptformidleren keeps track of changes for patients belongig to a single multidose responsibility registration (Practitioner+Organisation)
Kjernejournal exposes a general service to poll for changes on a list of patients.
GET [base]/Task?code=8&owner=<HPR>&_lastUpdated=gt<dateTime>
Organisation is implicit given claims in HelseID token, owner is optional and overrides personal identity in token. This operation may be perfomed without personal identity in token.
Note the following: Code=8 is from codesystem: sfm-task-types and is "Endring på multidosepasient" Returns a list with one task for each multidosepatient registered in the given combination (organisation /practitioner) having changes in Reseptformidleren since the _lastUpdated time.
GET [base]/Task?code=10&_lastUpdated=gt<dateTime>&PatientNiN=a,b,c...
Organisation is implicit given claims in HelseID token. PatientNiN contains a list of patients to check for changes against Kjernejournal This operation may be perfomed without personal identity in token.
Note the following: Code=10 is from codesystem: sfm-task-types and is "Endring på pasient" Returns a list with one task for each patient having changes in medicaton in Kjernejournal since the _lastUpdated time.
Create operation on Task is not available
Delete operation on Task is not available
Search operation directly on Task without given code will not trig a lookup in national systems
Search operations on Task other than described here have an upredictable result
The most relevant action for sfm-Task is the seach operations defined.
The format of the return is a search bundle containing tasks. Each task will have a "Patient" referred from for field. This reference is to a contained sfm-Patient within the Task.
| SfmTask (Task) | I | Task | Element idTask Actions required in SFM DefinitionThe SFM-Oppgave is used to identify actions that must be taken in SFM.
| |
| id | Σ | 0..1 | id | There are no (further) constraints on this element Element idTask.id Logical id of this artifact DefinitionThe logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes. The only time that a resource does not have an id is when it is being submitted to the server using a create operation.
|
| meta | Σ | 0..1 | Meta | There are no (further) constraints on this element Element idTask.meta Metadata about the resource DefinitionThe 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.
|
| implicitRules | Σ ?! | 0..1 | uri | There are no (further) constraints on this element Element idTask.implicitRules A set of rules under which this content was created DefinitionA 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. 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.
|
| language | 0..1 | codeBinding | There are no (further) constraints on this element Element idTask.language Language of the resource content DefinitionThe base language in which the resource is written. 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). A human language.
| |
| text | 0..1 | Narrative | There are no (further) constraints on this element Element idTask.text Text summary of the resource, for human interpretation Alternate namesnarrative, html, xhtml, display DefinitionA 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. 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.
| |
| contained | 0..* | Resource | There are no (further) constraints on this element Element idTask.contained Contained, inline Resources Alternate namesinline resources, anonymous resources, contained resources DefinitionThese 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. 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.
| |
| extension | I | 0..* | Extension | There are no (further) constraints on this element Element idTask.extension Additional content defined by implementations Alternate namesextensions, user content DefinitionMay 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. 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. Unordered, Open, by url(Value) Extensions are always sliced by (at least) url Constraints
|
| modifierExtension | ?! I | 0..* | Extension | There are no (further) constraints on this element Element idTask.modifierExtension Extensions that cannot be ignored Alternate namesextensions, user content DefinitionMay 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). 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. 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. Unordered, Open, by url(Value) Extensions are always sliced by (at least) url Constraints
|
| identifier | 0..* | Identifier | There are no (further) constraints on this element Element idTask.identifier Task Instance Identifier DefinitionThe business identifier for this task.

| instantiatesCanonical | Σ | 0..0 | canonical(ActivityDefinition) | There are no (further) constraints on this element Element idTask.instantiatesCanonical Formal definition of task DefinitionThe URL pointing to a FHIR-defined protocol, guideline, orderset or other definition that is adhered to in whole or in part by this Task. Enables a formal definition of how he task is to be performed, enabling automation.
|
| instantiatesUri | Σ | 0..0 | uri | There are no (further) constraints on this element Element idTask.instantiatesUri Formal definition of task DefinitionThe URL pointing to an externally maintained protocol, guideline, orderset or other definition that is adhered to in whole or in part by this Task. Enables a formal definition of how he task is to be performed (e.g. using BPMN, BPEL, XPDL or other formal notation to be associated with a task), enabling automation. see http://en.wikipedia.org/wiki/Uniform_resource_identifier
|
| basedOn | Σ I | 0..0 | Reference(Resource) | There are no (further) constraints on this element Element idTask.basedOn Request fulfilled by this task DefinitionBasedOn 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. References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.
|
| groupIdentifier | Σ | 0..0 | Identifier | There are no (further) constraints on this element Element idTask.groupIdentifier Requisition or grouper id DefinitionAn identifier that links together multiple tasks and other requests that were created in the same context. Billing and/or reporting can be linked to whether multiple requests were created as a single unit.
|
| partOf | Σ I | 0..0 | Reference(Task) | There are no (further) constraints on this element Element idTask.partOf Composite task DefinitionTask that this particular task is part of. Allows tasks to be broken down into sub-steps (and this division can occur independent of the original task). This should usually be 0..1.
|
| status | S Σ ?! | 1..1 | codeBinding | Element idTask.status draft | requested | received | accepted | + DefinitionThe current status of the task. All tasks created by SFM will initially have status "reqested". For some tasks EHR will be able to report that the task is fulfilled. This should then be set to completed. These states enable coordination of task status with off-the-shelf workflow solutions that support automation of tasks. Note that FHIR strings SHALL NOT exceed 1MB in size The current status of the task.
|
| statusReason | Σ | 0..0 | CodeableConcept | There are no (further) constraints on this element Element idTask.statusReason Reason for current status DefinitionAn explanation as to why this task is held, failed, was refused, etc. This applies to the current status. Look at the history of the task to see reasons for past statuses. Codes to identify the reason for current status. These will typically be specific to a particular workflow.
|
| businessStatus | Σ | 0..0 | CodeableConcept | There are no (further) constraints on this element Element idTask.businessStatus E.g. "Specimen collected", "IV prepped" DefinitionContains business-specific nuances of the business state. There's often a need to track substates of a task - this is often variable by specific workflow implementation. Not all terminology uses fit this general pattern. In some cases, models should not use CodeableConcept and use Coding directly and provide their own structure for managing text, codings, translations and the relationship between elements and pre- and post-coordination. The domain-specific business-contextual sub-state of the task. For example: "Blood drawn", "IV inserted", "Awaiting physician signature", etc.
|
| intent | S Σ | 1..1 | codeBinding | Element idTask.intent unknown | proposal | plan | order | original-order | reflex-order | filler-order | instance-order | option DefinitionSFM will only use "order". This element is immutable. Proposed tasks, planned tasks, etc. must be distinct instances. In most cases, Tasks will have an intent of "order". Distinguishes whether the task is a proposal, plan or full order.
|
| priority | 0..1 | codeBinding | There are no (further) constraints on this element Element idTask.priority routine | urgent | asap | stat DefinitionIndicates how quickly the Task should be addressed with respect to other requests. Used to identify the service level expected while performing a task. Note that FHIR strings SHALL NOT exceed 1MB in size If missing, this task should be performed with normal priority The task's priority.
| |
| code | S Σ | 1..1 | CodeableConceptBinding | Element idTask.code Task Type DefinitionExamples of task types are:
The title (eg "My Tasks", "Outstanding Tasks for Patient X") should go into the code. Codes to identify what the task involves. These will typically be specific to a particular workflow.
|
| id | 0..1 | There are no (further) constraints on this element Element idTask.code.id Unique id for inter-element referencing DefinitionUnique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
| ||
| extension | I | 0..* | Extension | There are no (further) constraints on this element Element idTask.code.extension Additional content defined by implementations Alternate namesextensions, user content DefinitionMay be used to represent additional information that is not part of the basic definition of the element. 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. 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. Unordered, Open, by url(Value) Extensions are always sliced by (at least) url Constraints
|
| coding | Σ | 0..* | Coding | There are no (further) constraints on this element Element idTask.code.coding Code defined by a terminology system DefinitionA reference to a code defined by a terminology system. Allows for alternative encodings within a code system, and translations to other code systems. Codes may be defined very casually in enumerations, or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information. Ordering of codings is undefined and SHALL NOT be used to infer meaning. Generally, at most only one of the coding values will be labeled as UserSelected = true.
|
| id | 0..1 | There are no (further) constraints on this element Element idTask.code.coding.id Unique id for inter-element referencing DefinitionUnique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

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.

|
| system | Σ | 0..1 | uriFixed Value | Element idTask.code.coding.system Identity of the terminology system DefinitionThe identification of the code system that defines the meaning of the symbol in the code. Need to be unambiguous about the source of the definition of the symbol. The URI may be an OID (urn:oid:...) or a UUID (urn:uuid:...). OIDs and UUIDs SHALL be references to the HL7 OID registry. Otherwise, the URI should come from HL7's list of FHIR defined special URIs or it should reference to some definition that establishes the system clearly and unambiguously.

|
| version | Σ | 0..1 | string | There are no (further) constraints on this element Element idTask.code.coding.version Version of the system - if relevant DefinitionThe version of the code system which was used when choosing this code. Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged. Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.
|
| code | Σ | 1..1 | code | There are no (further) constraints on this element Element idTask.code.coding.code Symbol in syntax defined by the system DefinitionA symbol in syntax defined by the system. The symbol may be a predefined code or an expression in a syntax defined by the coding system (e.g. post-coordination). Need to refer to a particular code in the system. Note that FHIR strings SHALL NOT exceed 1MB in size
|
| display | Σ | 1..1 | string | There are no (further) constraints on this element Element idTask.code.coding.display Representation defined by the system DefinitionA representation of the meaning of the code in the system, following the rules of the system. Need to be able to carry a human-readable meaning of the code for readers that do not know the system. Note that FHIR strings SHALL NOT exceed 1MB in size
|
| userSelected | Σ | 0..1 | boolean | There are no (further) constraints on this element Element idTask.code.coding.userSelected If this coding was chosen directly by the user DefinitionIndicates that this coding was chosen by a user directly - e.g. off a pick list of available items (codes or displays). This has been identified as a clinical safety criterium - that this exact system/code pair was chosen explicitly, rather than inferred by the system based on some rules or language processing. Amongst a set of alternatives, a directly chosen code is the most appropriate starting point for new translations. There is some ambiguity about what exactly 'directly chosen' implies, and trading partner agreement may be needed to clarify the use of this element and its consequences more completely.
|
| text | Σ | 0..1 | string | There are no (further) constraints on this element Element idTask.code.text Plain text representation of the concept DefinitionA human language representation of the concept as seen/selected/uttered by the user who entered the data and/or which represents the intended meaning of the user. The codes from the terminologies do not always capture the correct meaning with all the nuances of the human using them, or sometimes there is no appropriate code at all. In these cases, the text is used to capture the full meaning of the source. Very often the text is the same as a displayName of one of the codings.
|
| description | S Σ | 1..1 | string | Element idTask.description Human-readable explanation of task DefinitionIncludes the text that should be shown to the user within the work list. Note that FHIR strings SHALL NOT exceed 1MB in size
|
| focus | Σ I | 0..0 | Reference(Resource) | There are no (further) constraints on this element Element idTask.focus What task is acting on DefinitionThe request being actioned or the resource being manipulated by this task. Used to identify the thing to be done. If multiple resources need to be manipulated, use sub-tasks. (This ensures that status can be tracked independently for each referenced resource.).
|
| for | S Σ I | 0..1 | Reference(sfm-Patient) | Element idTask.for Beneficiary of the Task Alternate namesPatient DefinitionThe entity who benefits from the performance of the service specified in the task (e.g., the patient). Used to track tasks outstanding for a beneficiary. Do not use to track the task owner or creator (see owner and creator respectively). This can also affect access control. References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.
|
| encounter | Σ I | 0..0 | Reference(Encounter) | There are no (further) constraints on this element Element idTask.encounter Healthcare event during which this task originated DefinitionThe healthcare event (e.g. a patient and healthcare provider interaction) during which this task was created. For some tasks it may be important to know the link between the encounter the task originated within. References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.
|
| executionPeriod | Σ I | 0..0 | Period | There are no (further) constraints on this element Element idTask.executionPeriod Start and end time of execution DefinitionIdentifies the time action was first taken against the task (start) and/or the time final action was taken against the task prior to marking it as completed (end). A Period specifies a range of time; the context of use will specify whether the entire range applies (e.g. "the patient was an inpatient of the hospital for this time range") or one value from the range applies (e.g. "give to the patient between these two times"). Period is not used for a duration (a measure of elapsed time). See Duration.
|
| authoredOn | S I | 0..1 | dateTime | There are no (further) constraints on this element Element idTask.authoredOn Task Creation Date Alternate namesCreated Date DefinitionThe date and time this task was created. Most often used along with lastUpdated to track duration of task to supporting monitoring and management.
|
| lastModified | S Σ I | 0..1 | dateTime | There are no (further) constraints on this element Element idTask.lastModified Task Last Modified Date Alternate namesUpdate Date DefinitionThe date and time of last modification to this task. Used along with history to track task activity and time in a particular task state. This enables monitoring and management.
|
| requester | Σ I | 0..1 | Reference(Device | sfm-PractitionerRole) | Element idTask.requester Who is asking for task to be done DefinitionThe creator of the task. Identifies who created this task. May be used by access control mechanisms (e.g., to ensure that only the creator can cancel a task). References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository. Reference(Device | sfm-PractitionerRole) Constraints
|
| performerType | S | 0..* | CodeableConceptBinding | There are no (further) constraints on this element Element idTask.performerType Requested performer DefinitionThe kind of participant that should perform the task. Use to distinguish tasks on different activity queues. Not all terminology uses fit this general pattern. In some cases, models should not use CodeableConcept and use Coding directly and provide their own structure for managing text, codings, translations and the relationship between elements and pre- and post-coordination. The type(s) of task performers allowed.
|
| owner | S Σ I | 0..1 | Reference(sfm-Practitioner | SfmOrganization) | Element idTask.owner Responsible individual Alternate namesPerformer, Executer DefinitionIndividual or organization currently responsible for task execution. Identifies who is expected to perform this task. Tasks may be created with an owner not yet identified. Reference(sfm-Practitioner | SfmOrganization) Constraints
|
| location | Σ I | 0..0 | Reference(Location) | There are no (further) constraints on this element Element idTask.location Where task occurs DefinitionPrincipal physical location where the this task is performed. Ties the event to where the records are likely kept and provides context around the event occurrence (e.g. if it occurred inside or outside a dedicated healthcare setting). References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.
|
| reasonCode | 0..0 | CodeableConcept | There are no (further) constraints on this element Element idTask.reasonCode Why task is needed DefinitionA description or code indicating why this task needs to be performed. This should only be included if there is no focus or if it differs from the reason indicated on the focus. Indicates why the task is needed. E.g. Suspended because patient admitted to hospital.
| |
| reasonReference | I | 0..0 | Reference(Resource) | There are no (further) constraints on this element Element idTask.reasonReference Why task is needed DefinitionA resource reference indicating why this task needs to be performed. Tasks might be justified based on an Observation, a Condition, a past or planned procedure, etc. This should only be included if there is no focus or if it differs from the reason indicated on the focus. Use the CodeableConcept text element in
|
| insurance | I | 0..0 | Reference(Coverage | ClaimResponse) | There are no (further) constraints on this element Element idTask.insurance Associated insurance coverage DefinitionInsurance plans, coverage extensions, pre-authorizations and/or pre-determinations that may be relevant to the Task. References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository. Reference(Coverage | ClaimResponse) Constraints
|
| note | 0..0 | Annotation | There are no (further) constraints on this element Element idTask.note Comments made about the task DefinitionFree-text information captured about the task as it progresses. For systems that do not have structured annotations, they can simply communicate a single annotation with no author or time. This element may need to be included in narrative because of the potential for modifying information. Annotations SHOULD NOT be used to communicate "modifying" information that could be computable. (This is a SHOULD because enforcing user behavior is nearly impossible).
| |
| relevantHistory | I | 0..0 | Reference(Provenance) | There are no (further) constraints on this element Element idTask.relevantHistory Key events in history of the Task Alternate namesStatus History DefinitionLinks 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. 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.
|
| restriction | 0..0 | BackboneElement | There are no (further) constraints on this element Element idTask.restriction Constraints on fulfillment tasks DefinitionIf 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. Sometimes when fulfillment is sought, you don't want full fulfillment.
| |
| input | 0..0 | BackboneElement | There are no (further) constraints on this element Element idTask.input Information used to perform task Alternate namesSupporting Information DefinitionAdditional information that may be needed in the execution of the task. Resources and data used to perform the task. This data is used in the business logic of task execution, and is stored separately because it varies between workflows.
| |
| output | 0..0 | BackboneElement | There are no (further) constraints on this element Element idTask.output Information produced as part of task DefinitionOutputs produced by the Task. Resources and data produced during the execution the task. This data is generated by the business logic of task execution, and is stored separately because it varies between workflows.
