Detailed Descriptions

RequestGroup
DefinitionA group of related requests that can be used to capture intended activities that have inter-dependencies such as "give this medication after that one".
Cardinality0...*
Invariants
  • dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources
    contained.contained.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-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-6: A resource should have narrative for robust management
    text.`div`.exists()
  • dom-5: If a resource is contained in another resource, it SHALL NOT have a security label
    contained.meta.security.empty()
Mappings
  • rim: Entity. Role, or Act
  • workflow: Request
RequestGroup.id
DefinitionThe logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.
Cardinality0...1
Typestring
SummaryTrue
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.

RequestGroup.meta
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.
Cardinality0...1
TypeMeta
SummaryTrue
Invariants
  • ele-1: All FHIR elements must have a @value or children
    hasValue() or (children().count() > id.count())
Mappings
  • rim: n/a
  • rim: N/A
RequestGroup.implicitRules
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.
Cardinality0...1
Typeuri
ModifierTrue
SummaryTrue
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
  • ele-1: All FHIR elements must have a @value or children
    hasValue() or (children().count() > id.count())
Mappings
  • rim: n/a
RequestGroup.language
DefinitionThe base language in which the resource is written.
Cardinality0...1
Typecode
Binding

A human language.

CommonLanguages (preferred)
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
  • ele-1: All FHIR elements must have a @value or children
    hasValue() or (children().count() > id.count())
Mappings
  • rim: n/a
RequestGroup.text
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.
Cardinality0...1
TypeNarrative
Aliasnarrative, 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
  • ele-1: All FHIR elements must have a @value or children
    hasValue() or (children().count() > id.count())
Mappings
  • rim: n/a
  • rim: N/A
  • rim: Act.text?
RequestGroup.contained
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.
Cardinality0...*
TypeResource
Aliasinline 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
  • rim: Entity. Role, or Act
  • rim: N/A
RequestGroup.extension
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.
Cardinality0...*
TypeExtension
Aliasextensions, 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.

    extension.exists() != value.exists()
Mappings

  • rim: N/A
RequestGroup.modifierExtension
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).
Cardinality0...*
TypeExtension
ModifierTrue
Aliasextensions, 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.

Requirements

Allows tracing of authorization for the request and tracking whether proposals/recommendations were acted upon.

Comments

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.

Aliassupersedes, prior, renewed order
Requirements

Allows tracing the continuation of a therapy or administrative process instantiated through multiple requests.

Comments

The replacement could be because the initial request was immediately rejected (due to an issue) or because the previous request was completed, but the need for the action described by the request remains ongoing.

DefinitionA shared identifier common to all requests that were authorized more or less simultaneously by a single author, representing the identifier of the requisition, prescription or similar form.
Cardinality0...1
TypeIdentifier
SummaryTrue
Aliasgrouperid, requisition
Requirements

Some business processes need to know if multiple items were ordered as part of the same "prescription" or "requisition" for billing or other purposes.

Comments

Requests are linked either by a "basedOn" relationship (i.e. one request is fulfilling another) or by having a common requisition. Requests that are part of the same requisition are generally treated independently from the perspective of changing their state or maintaining them after initial creation.

For systems that do not have structured annotations, they can simply communicate a single annotation with no author or time.

(This is a SHOULD because enforcing user behavior is nearly impossible).

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.

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.

Example Usage Scenarios

The following are example usage scenarios for the UK Core RequestGroup profile:

An example of the same drug, different route

This example shows how a request for the same drug through two different routes can be structured, with the decision to the more appropriate route being taken before a dispense is made.

RequestGroup-Paracetamol

An example of different drugs, with a preference to one of them

This example shows how a request can be achieved giving the option for multiple different drugs, with one being preferred option and up to one being allowed to be dispensed.

RequestGroup-MultipleAntibiotics

An example of same drug different doses, where both are dispensed but only one administered

This example shows a request of the same drug each with a different dose and route. This request allows both to be dispensed, with one being administered now and the other that may be dispensed at a later date or disposed.

RequestGroup-Ciprofloxacin

Profile Specific Implementation Guidance:

Minimum Viable Content

A minimum viable content that all provider and consumer systems SHALL support are the following elements.

Element Reason
status The current state of the request. For request groups, the status reflects the status of all the requests in the group.
intent Indicates the level of authority/intentionality associated with the request and where the request fits into the workflow chain.
subject The subject for which the request group was created.
action.description A short description of the action used to provide a summary to display to the user.
action.type The type of action to perform (create, update, remove).
action.selectionBehavior Defines the selection behavior for the action and its children.
action.resource The resource that is the target of the action (e.g. CommunicationRequest).
action.action Sub actions.

intent

For any medication requests RequestGroup.intent SHALL have the value order. Each MedicationRequest referenced within the RequestGroup MedicationRequest.intent SHALL have the value option.

priority

When RequestGroup is used for medication requests the recommendation is that RequestGroup.priority is not to be used within an implementation - or used with caution.

The stating of a priority, in any business context including healthcare, is often de-valued as given the choice, every clinician wants medication urgently for their patients.

If RequestGroup.priority is used, consider only initially supporting the routine and urgent request priorities, and set clear criteria for when a MedicationRequest and RequestGroup should be marked and handled as urgent.

Usage of the value "stat"

The stat request priority is potentially confusing as it has two meanings:

  1. to indicate a "here and now" order going to pharmacy
  2. used within a MedicationRequest.dosageInstruction can also mean "give once immediately".

Avoid using stat and asap where possible.
