D.4.1.4 StructureDefinition: - Detailed Descriptions

Definitions for the StructureDefinition-us-core-procedure Profile.

Procedure
Definition

The US Core Condition Profile is based upon the core FHIR Procedure Resource and created to meet the 2015 Edition Common Clinical Data Set 'Procedures' requirements.

Control0..*
InvariantsDefined on this element
dom-1: If the resource is contained in another resource, it SHALL NOT contain any narrative (: contained.text.empty())
dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources (: contained.contained.empty())
dom-3: If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource (: contained.where(('#'+id in %resource.descendants().reference).not()).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())
pro-1: Reason not done is only permitted if notDone indicator is true (: notDoneReason.empty() or notDone = true)
Procedure.id
Definition

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

Control0..1
Typeid
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.

Procedure.meta
Definition

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.

Control0..1
TypeMeta
Procedure.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.

Control0..1
Typeuri
Is Modifiertrue
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.

This element is labelled as a modifier because the implicit rules may provide additional knowledge about the resource that modifies it's meaning or interpretation.

Procedure.language
Definition

The base language in which the resource is written.

Control0..1
BindingA human language.
The codes SHALL be taken from Common Languages; other codes may be used where these codes are not suitable
Typecode
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).

Procedure.text
Definition

A human-readable narrative that contains a summary of the resource, and may 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.

Control0..1 This element is affected by the following invariants: dom-1
TypeNarrative
Alternate Namesnarrative, 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 in formation is added later.

Procedure.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.

Control0..*
TypeResource
Alternate Namesinline 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.

Procedure.extension
Definition

May be used to represent additional information that is not part of the basic definition of the resource. In order 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.

Control0..*
TypeExtension
Alternate Namesextensions, 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.

Procedure.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. Usually modifier elements provide negation or qualification. In order 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.

Control0..*

Comments

Procedure.identifier
Definition

This records identifiers associated with this procedure that are defined by business processes and/or used to refer to it when a direct URL reference to the resource itself is not appropriate (e.g. in CDA documents, or in written / printed documentation).

NoteThis is a business identifer, not a resource identifier (see discussion)
Control0..*
TypeIdentifier
Requirements

Need to allow connection to a wider workflow.

Procedure.definition
Definition

A protocol, guideline, orderset or other definition that was adhered to in whole or in part by this procedure.

Control0..*
TypeChoice of: Reference(PlanDefinition), Reference(ActivityDefinition), Reference(HealthcareService)
Procedure.basedOn
Definition

A reference to a resource that contains details of the request for this procedure.

Control0..*
TypeChoice of: Reference(CarePlan), Reference(ProcedureRequest), Reference(ReferralRequest)
Alternate Namesfulfills
Procedure.partOf
Definition

A larger event of which this particular procedure is a component or step.

Control0..*
TypeChoice of: Reference(Procedure), Reference(Observation), Reference(MedicationAdministration)
Alternate Namescontainer
Comments

The MedicationAdministration has a partOf reference to Procedure, but this is not a circular reference. For a surgical procedure, the anesthesia related medicationAdministration is part of the procedure. For an IV medication administration, the procedure to insert the IV port is part of the medication administration.

Procedure.status
Definition

A code specifying the state of the procedure. Generally this will be in-progress or completed state.

Control1..1
BindingThe codes SHALL be taken from EventStatus
Typecode
Is Modifiertrue
Must Supporttrue
Comments

The unknown code is not to be used to convey other statuses. The unknown code should be used when one of the statuses applies, but the authoring system doesn't know the current state of the procedure.

This element is labeled as a modifier because the status contains codes that mark the resource as not currently valid.

Procedure.notDone
Definition

Set this to true if the record is saying that the procedure was NOT performed.

Control0..1
Typeboolean
Is Modifiertrue
Comments

If true, it means the procedure did not occur as described. Typically it would be accompanied by attributes describing the type of activity. It might also be accompanied by body site information or time information (i.e. no procedure was done to the left arm or no procedure was done in this 2-year period). Specifying additional information such as performer, outcome, etc. is generally inappropriate. For example, it's not that useful to say "There was no appendectomy done at 12:03pm June 6th by Dr. Smith with a successful outcome" as it implies that there could have been an appendectomy done at any other time, by any other clinician or with any other outcome.

This element is labeled as a modifier because it indicates that a procedure didn't happen.

Default Valuefalse
Procedure.notDoneReason
Definition
