HL7 International / Clinical Quality Information
Positive profile of DeviceRequest for decision support/quality metrics. Indicates a proposal, plan, or order for a device.
Quality Improvement and Clinical Knowledge (QUICK)
Represents a request for a patient to employ a medical device. The device may be an implantable device, or an external assistive device, such as a walker.
If the resource is contained in another resource, it SHALL NOT contain nested Resources
not(parent::f:contained and f:contained)
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()
not(exists(for $id in f:contained/*/f:id/@value return $contained[not(parent::*/descendant::f:reference/@value=concat('#', $contained/*/id/@value) or descendant::f:reference[@value='#'])]))
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()
not(exists(f:contained/*/f:meta/f:versionId)) and not(exists(f:contained/*/f:meta/f:lastUpdated))
If a resource is contained in another resource, it SHALL NOT have a security label
When a resource has no narrative, only systems that fully understand the data can display the resource to a human safely. Including a human readable representation in the resource makes for a much more robust eco-system and cheaper handling of resources by intermediary systems. Some ecosystems restrict distribution of resources to only those systems that do fully understand the resources, and as a consequence implementers may believe that the narrative is superfluous. However experience shows that such eco-systems often open up to new participants over time.
A resource should have narrative for robust management
to indicate what device, either at least one coding in the code or a codeOptions extension shall be provided
(code is Reference).not() implies code.extension('http://hl7.org/fhir/StructureDefinition/codeOptions').exists() xor code.coding.exists()
The 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.
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.
All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count())
A set of rules under which this content was created
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.
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.
This element is labeled as a modifier because the implicit rules may provide additional knowledge about the resource that modifies it's meaning or interpretation
The 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).
Text summary of the resource, for human interpretation
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.
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.
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.
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.
Additional content defined by implementations
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.
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.
Must have either extensions or value[x], not both
exists(f:extension)!=exists(f:*[starts-with(local-name(.), "value")])
Modifier extensions are expected to modify the meaning or interpretation of the resource that contains them
exists(f:extension)!=exists(f:*[starts-with(local-name(.), 'value')])
The do not perform element changes the meaning of the request from a positive to a negative statement
Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Extensions are always sliced by (at least) url
Source of the definition for the extension code - a logical name or a URL.
The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension.
Value of extension - must be one of a constrained set of the data types (see [Extensibility](http://hl7.org/fhir/R4/extensibility.html) for a list).
Identifiers assigned to this order by the orderer or by the receiver.
Instantiates FHIR protocol or definition
The URL pointing to a FHIR-defined protocol, guideline, orderset or other definition that is adhered to in whole or in part by this DeviceRequest.
Note: This is a business identifier, not a resource identifier (see [discussion](http://hl7.org/fhir/R4/resource.html#identifiers)). It is best practice for the identifier to only appear on a single resource instance, however business practices may occasionally dictate that multiple resource instances with the same identifier can exist - possibly even with different resource types. For example, multiple Patient and a Person resource instance might share the same social insurance number.
Instantiates external protocol or definition
The URL pointing to an externally maintained protocol, guideline, orderset or other definition that is adhered to in whole or in part by this DeviceRequest.
This might be an HTML page, PDF, etc. or could just be a non-resolvable URI identifier.
Plan/proposal/order fulfilled by this request.
The request takes the place of the referenced completed or terminated request(s).
Handled by message location of ORC (ORC.1=RO or RU)
(QI) draft | active | on-hold | revoked | completed | entered-in-error | unknown
This element is labeled as a modifier because the status contains the codes cancelled and entered-in-error that mark the request as not currently valid.
This element is labeled as a modifier because it is a status element that contains status entered-in-error which means that the resource should not be treated as valid
Codes representing the status of the request.
(QI) proposal | plan | directive | order | original-order | reflex-order | filler-order | instance-order | option
Whether the request is a proposal, plan, an original order or a reflex order.
This element changes the interpretation of all descriptive attributes. For example "the time the request is recommended to occur" vs. "the time the request is authorized to occur" or "who is recommended to perform the request" vs. "who is authorized to perform the request
.moodCode (nuances beyond PRP/PLAN/RQO would need to be elsewhere)
Indicates how quickly the {{title}} should be addressed with respect to other requests.
Identifies the level of importance to be assigned to actioning the request.
Codes for devices that can be requested.
May 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.
(QI) Url of a value set of candidate devices
A logical reference (e.g. a reference to ValueSet.url) to a value set/version that identifies a set of possible coded values representing the device.
This extension SHALL NOT be used when an appropriate higher level concept code exists. When this extension is used on an element with a required binding, the set of possible coded values in the referenced value set SHALL be present in the bound value set. When used with an extensible binding, the set of possible coded values in the referenced value set SHALL be present in the bound value set unless none of the codes in the bound value set apply to the concept being communicated (based on human review). When this extension appears on a CodeableConcept, the CodeableConcept SHALL have no codings, and the text of the CodeableConcept SHALL include the title of the referenced value set.
A reference to a code defined by a terminology system.
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.
Allows for alternative encodings within a code system, and translations to other code systems.
fhir:CodeableConcept.coding rdfs:subPropertyOf dt:CD.coding
Plain text representation of the concept
A 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.
Very often the text is the same as a displayName of one of the codings.
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.
C*E.9. But note many systems use C*E.2 for this
fhir:CodeableConcept.text rdfs:subPropertyOf dt:CD.originalText
Specific parameters for the ordered item. For example, the prism value for lenses.
Extensions that cannot be ignored even if unrecognized
May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained 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 can 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](http://hl7.org/fhir/R4/extensibility.html#modifierExtension).
Modifier extensions are expected to modify the meaning or interpretation of the element that contains them
A code or string that identifies the device detail being asserted.
A code that identifies the device detail.
Range means device should have a value that falls somewhere within the specified range.
An encounter that provides additional context in which this request is made.
.inboundRelationship(typeCode=COMP].source[classCode<=PCPR, moodCode=EVN]
The timing schedule for the use of the device. The Schedule data type allows many different expressions, for example. "Every 8 hours"; "Three times a day"; "1/2 an hour before breakfast for 10 days from 23-Dec 2011:"; "15 Oct 2013, 17 Oct 2013 and 1 Nov 2013".
When the request transitioned to being actionable.
The individual who initiated the request and has responsibility for its activation.
Desired type of performer for doing the diagnostic testing.
Indicates specific responsibility of an individual within the care team, such as "Primary physician", "Team coordinator", "Caregiver", etc.
The desired performer for doing the diagnostic testing.
Reason or justification for the use of this device.
Diagnosis or problem codes justifying the reason for requesting the device.
Insurance plans, coverage extensions, pre-authorizations and/or pre-determinations that may be required for delivering the requested service.
Additional clinical information about the patient that may influence the request fulfilment. For example, this may include where on the subject's body the device will be used (i.e. the target site).
Knowing where the device is targeted is important for tracking if multiple sites are possible.
Details about this request that were not represented at all or sufficiently in one of the attributes provided in a class. These may include for example a comment, an instruction, or a note associated with the statement.
.inboundRelationship(typeCode=SUBJ].source[classCode=ANNGEN, moodCode=EVN].value[xsi:type=ST]
Key events in the history of the request.
This might not include provenances for all versions of the request - only those deemed "relevant" or important. This SHALL NOT include the Provenance associated with this current version of the resource. (If that provenance is deemed to be a "relevant" change, it will need to be added as part of a later update. Until then, it can be queried directly as the Provenance that points to this version using _revinclude All Provenances should have some historical version of this Request as their subject.
