NameCard.TypeConstraints and Usage
.  Task 0..*PrescribeIT® base Task profileinv-2: A Failure reason may be present only when a task has failed.
inv-1: Last modified date must be greater than or equal to created date.
Definition:
A task to be performed.

..  id 1..1idDefinition:
The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.


Comments:
Usage Note: This will usually be a GUID and is assigned by the sending application.

..  meta 1..1MetaDefinition:
The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content may not always be associated with version changes to the resource.

...  profile 1..*uriDefinition:
A list of profiles [[[StructureDefinition]]]s that this resource claims to conform to. The URL is a reference to [[[StructureDefinition.url]]].


Comments:
It is up to the server and/or other infrastructure of policy to determine whether/how these claims are verified and/or updated over time.

..  extension 0..*ExtensionSlice: Unordered, Open by value:url
Definition:
An Extension

..  extension
     (groupIdentifier)
1..1Task Group IdentifierDefinition:
This is the common identifier that represents a paper order. It may be shared by multiple Task instances for various Medication Orders, reflecting multiple requests that are authorized simultaneously for a patient by a single prescriber


Comments:
Usage Note: This business identifier is assigned by the sending application and is used to group tasks together that need to be processed and managed together. Refer to the PrescribeIT® Version 5.0 Jurisdictional Rules and Task Grouping Excel spreadsheet rules for a full set of scenarios.

..  extension
     (basedOn)
1..1Task Order Based OnDefinition:
Identifies a request, plan or proposal that drove the creation of this task


Comments:
Usage Note: The URL for this extension does not refer to an existing web-page as is a pre-adoption extension. Refer to the Shared Health implementation Guide for more information.

...  url 1..1uri"http://hl7.org/fhir/StructureDefinition/extension-Task.basedOn"
...  value[x] 1..1Reference() {r}Slice: Unordered, Closed by type:$this
Definition:
The identifier of the request task that this task was created based on


Comments:
Conformance Rule: The will be a URN (form urn:uuid:[guid]) containing the Task.id for the task being responded to

...  value[x]
       (valueReference)
1..1Reference() {r}Definition:
Value of extension - may be a resource or one of a constrained set of the data types (see Extensibility in the spec for list).

....  reference 1..1stringDefinition:
A reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found. The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources.


Comments:
Conformance Rule: This shall be the Task.id of the request task being responded to, expressed as a uri (i.e. urn:uuid:[original task id])

..  type 1..1Shared Health CodeableConcept CodeBinding: PrescriptionTaskType (20220913) (required)
Definition:
A concept that may be defined by a formal reference to a terminology or ontology or may be provided by text.


Comments:
This will be a fixed code for each type of task. Review usage comments on child elements.

..  status 1..1codeBinding: TaskStatus (required): The current status of the task.


Definition:
The current status of the task.


Comments:
This will be fixed based on the task code being used as the architecture calls for different tasks for each state rather than updating of existing tasks.

..  subject 0..1Reference(Resource)Definition:
The subject of the task.

..  for 1..1Reference(Shared Health Patient) {b}Definition:
The entity who benefits from the performance of the service specified in the task (e.g., the patient).


Comments:
Identifies the patient tied to the task. (FHIR prohibits inheritance of context, so this must be explicitly declared rather than inferred from the presence of the Patient resource in the message)

...  reference 1..1stringDefinition:
A reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found. The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources.


Comments:
This is a reference to the Patient associated with the task. It will be a URN pointing to the id of the patient record in the message

..  created 1..1dateTimecreated-full: Must be at least a full date. i.e. yyyy-mm-dd
Definition:
The date and time this task was created.


Comments:
This indicates when the request was created. This will generally be the same as the date of message construction.



Conformance Rule: Date-Time must be specified down to the day. Time is optional and may be ignored.



Usage Note: If time is present, FHIR requires the UTC offset and for time to be specified down to the seconds. If seconds aren't available, they may be filled with '00'

..  lastModified 1..1dateTimelastModified-full: Must be at least a full date. i.e. yyyy-mm-dd
Definition:
The date and time of last modification to this task.


Comments:
This is required by FHIR but is not needed. It should generally be set to the same value as Task.created. This is the date of the most recent transaction as recorded in the EMR.



Usage Note: If time is present, FHIR requires the UTC offset and for time to be specified down to the seconds. If seconds aren't available, they may be filled with '00'.



Conformance Rule: PMS is not expected to display this date as it is irrelevant to the Pharmacist or to the processing of the discontinue notification.

..  creator 1..1Reference(Device | Organization | Patient | Practitioner | RelatedPerson)Definition:
The creator of the task.


Comments:
This is who is submitting the task and asking it be done
