Genomics-Task
The core workflow resource for managing processing of a ServiceRequest from order through to delivery of a DiagnosticReport and completion. Task tracking is a core requirement of the central Genomic Medicine Service.
Each ServiceRequest submitted will instantiate a series of High Level Tasks, which MAY be assigned to different organizations for managing the test request e.g. Sample Processing, Interpretation, Reporting etc. The full list of possible Task types/codes, their associated business statuses, and status reasons is pending internal review.
Tasks will be automatically created by the central service but updates to statuses and attachment of input/output resources is the responsibility of the assigned organizations.

|
Task.id | |
Definition | The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes. |
Cardinality | 0...1 |
Type | string |
Summary | True |
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. |
Task.meta | |
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. |
Cardinality | 0...1 |
Type | Meta |
Summary | True |
Invariants |
|
Mappings |
|
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. |
Cardinality | 0...1 |
Type | uri |
Modifier | True |
Summary | True |
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. |
Invariants |
|
Mappings |
|
Task.language | |
Definition | The base language in which the resource is written. |
Cardinality | 0...1 |
Type | code |
Binding | A human language. |
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). |
Invariants |
|
Mappings |
|
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. |
Cardinality | 0...1 |
Type | Narrative |
Alias | narrative, html, xhtml, display |
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. |
Invariants |
|
Mappings |
|
Task.contained | |
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. |
Cardinality | 0...* |
Type | Resource |
Alias | inline resources, anonymous resources, contained 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. |
Mappings |
|
Task.extension | |
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. |
Cardinality | 0...* |
Type | Extension |
Alias | extensions, user content |
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. |

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 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). |
Cardinality | 0...* |
Type | Extension |
Modifier | True |
Alias | extensions, user content |
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.

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, 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. |
Cardinality | 0...* |
Type | Reference(Resource) |
Summary | True |
Comments | References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.).

Summary | True |
Requirements | There's often a need to track substates of a task - this is often variable by specific workflow implementation. |
Comments | 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. |

This element will not be used within the Genomic Medicine Service. The ServiceRequest a Task is seeking to fulfill SHALL be referenced through the focus
element. Specimen resources being acted upon by tasks related to specimen prep/processing SHOULD be referenced through the Task.input
element.
status
Initially, automatically populated by the central service upon instantiation. Tasks will be first marked as 'requested' until accepted/claimed by an organization, or marked as 'draft' if their prerequisities have not been satisfied. Upon acceptance, the owning organization is responsible for updating the status up until completion (or if the owning organization is not integration into the GMS, the organization who has referred the task to the unintegrated org).
For the full list of expected Task statuses in use by the GMS, please refer to the table below:
Status | Description | Genomic workflow usage |
---|---|---|
Draft | The task is not yet ready to be acted upon. | May be used for tasks which require prerequisite tasks to be completed first |
Requested | The task is ready to be acted upon and action is sought. | Initial state of tasks when created |
Received | A potential performer has claimed ownership of the task and is evaluating whether to perform it. | Most likely not used unless tasks are automatically assigned by the central service, e.g. to GLH |
Accepted | The potential performer has agreed to execute the task but has not yet started work. | When assigned |
Rejected | The potential performer who claimed ownership of the task has decided not to execute it prior to performing any action. | Most likely used if an organization was assigned to a task but is unable to perform work against it |
Ready | The task is ready to be performed, but no action has yet been taken. Used in place of requested/received/accepted/rejected when request assignment and acceptance is a given. | Tasks ready to be picked up when prerequisites are satisfied |
Cancelled | The task was not completed. | Most likely used when a task has been created but later identified as unneeded, e.g. due to modifications to test order |
In Progress | The task has been started but is not yet complete. | When work has commenced |
On Hold | The task has been started but work has been paused. | May need to state reason why work is on hold e.g. awaiting sample |
Failed | The task was attempted but could not be completed due to some error. | Indicates the task cannot continue, if modifications to the test order allow the task to be resumed, a new task should be created |
Completed | The task has been completed. | Once complete |
Entered in Error | The task should never have existed and is retained only because of the possibility it may have used. | Unused |
"status": "rejected",
statusReason
Reasons why a Task has been marked as on-hold, cancelled etc. SHOULD use the Genomic-Task-StatusReason CodeSystem. NOTE: The list of appropriate statusReasons is pending finalization.
"statusReason": { "coding": [ { "system": "https://fhir.nhs.uk/CodeSystem/task-status-reason-genomics", "code": "Inappropriate", "display": "Inappropriate for patient" } ] },
businessStatus
Genomic specific business statuses for capturing more granular information as part of processing the task. SHOULD use the Genomic-Business-Status CodeSystem. NOTE: The list of appropriate buinessStatuses is pending finalization. Mapping business statuses to the high level container Tasks and statuses is still ongoing.
"businessStatus": { "coding": [ { "system": "https://fhir.nhs.uk/CodeSystem/business-status-genomics", "code": "InvalidRequest", "display": "Invalid Request" } ] },
code
High level coding for the Task, matches the NGTP stages for genomic test processing. SHOULD use the Genomic-Task-Code CodeSystem. NOTE: The list of appropriate codes is pending finalization.
"code": { "coding": [ { "system": "https://fhir.nhs.uk/CodeSystem/task-code-genomics", "code": "SampleProcessing", "display": "Sample Processing" } ] },
focus
The ServiceRequest the Task is fulfilling. Autopopulated by the central service.
"focus": { "reference": "ServiceRequest/ServiceRequest-SavedTestOrder-Example" },
for
A reference to the Patient resource or the identifier, NHS number, for the patient for whom the Task is for. Autopopulated by the central service.
"subject": { "reference": "Patient/Patient-MeirLieberman-Example", "identifier": { "system": "https://fhir.nhs.uk/Id/nhs-number", "value": "9449307873" } },
executionPeriod
MAY be used to capture start and end DateTimes associated with execution of a Task. It is expected the start time will be populated as a Task is moved to in-progress and the end time will be populated as a Task is marked as completed. Usage of this field will be investigated during the Alpha phase of the Genomic Order Management project as timelines for task execution can also be derived from the AuditEvents recorded as Tasks are updated.
"executionPeriod": { "start": "2023-10-31T10:25:05+00:00", "end": "2023-11-15T16:45:05+00:00" },
authoredOn
Autopopulated by the central service on creation of the Task.
"authoredOn": "2023-09-18T18:30:00Z"
lastModified
Time at which a change to the task was made, e.g. status updated. SHALL be updated on change.
"lastModified": "2023-09-18T19:11:00Z"
requester
The original requester of the ServiceRequest the Task is fulfilling. Autopopulated by the central service.
"requester": { "reference": "PractitionerRole/PractitionerRole-GeneSmithENT-Example" },
owner
Autopopulated by the central service if a performer is assigned at Test submission. Otherwise updated by the organization claiming the task (though this could also be autopopulated if automated per test routing tables are integrated into the central service functionality). Owner SHOULD be populated using organization ODS code references.
Tasks assigned to a particular organization SHOULD then be searched for using the owner
search parameter with the :identifier
modifier i.e. [base]/Task?owner:identifier=8J834
or [base]/Task?owner:identifier=https://fhir.nhs.uk/Id/ods-organization-code|8J834
"owner": { "identifier": { "system": "https://fhir.nhs.uk/Id/ods-organization-code", "value": "69010" }, "display": "Pathology Lab - ADDENBROOKE'S HOSPITAL LABORATORY" },
note
Used for messaging between owner and other orgnizations e.g. during handover of task or requesting information from requesting clinician
"note": [ { "text": "Sample has not been received within 4 week window. Task will be closed unless further communication is received" } ]
input
Used to attach inputs to a Task, if relevant. e.g. references to Specimen's which a Sample Processing task is acting on. No CodeSystem exists for this field as of publication but this will be investigated as future work.
Specimen references SHOULD be added to Tasks acting on Specimen resources, e.g. Tasks marked SamplePreparation or SampleProcessing. This is to clearly disambiguate which specimen a task is acting on, where multiple specimens are necessary for processing the test request.
"input": [ { "type": { "coding": [ { "system": "http://snomed.info/sct", "code": "123038009", "display": "Specimen" } ] }, "valueReference": { "reference": "Specimen/Specimen-CancerSolidTumor-Example" } } ]
output
Used to attach outputs from a Task, if relevant. e.g. VUS files during processing or a DiagnosticReport upon completion of reporting stage. No CodeSystem exists for this field as of publication but this will be investigated as future work.
Sample tracking information SHOULD be added to Tasks acting on Specimen resources, e.g. Tasks marked SamplePreparation or SampleProcessing, on either the output or input elements. This information MAY include consignment number, destination, date sent etc. Further modelling of the types/format expected are pending clinical scenarios.
