Canonical_URL	Status	Current_Version	Last_Updated	Description
https://fhir.hl7.org.uk/StructureDefinition/UKCore-Procedure	active	2.5.0	2023-12-12	This profile defines the UK constraints and extensions on the International FHIR resource Procedure.

Profile_Purpose
This profile allows exchange of details of current and historical procedures performed on or for an individual. A procedure is an activity that is performed on, with, or for an individual as part of the provision of care. Examples include surgical procedures, diagnostic procedures, endoscopic procedures, biopsies, counselling, physiotherapy, personal support services, adult day care services, non-emergency transportation, home modification, exercise, etc. Procedures may be performed by a healthcare professional, a service provider, a friend or relative or in some cases by themselves.

UKCoreProcedure (Procedure)	I		Procedure	There are no (further) constraints on this element Element id Procedure Short description An action that is being or was performed on a patient Definition An action that is or was performed on or for a patient. This can be a physical intervention like an operation, or less invasive like long term services, counseling, or hypnotherapy. Data type Procedure Constraints 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: Event rim: Procedure[moodCode=EVN]
id	Σ	0..1	string	There are no (further) constraints on this element Element id Procedure.id Short description Logical id of this artifact Definition The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes. 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. Data type string
meta	Σ	0..1	Meta	There are no (further) constraints on this element Element id Procedure.meta Short description Metadata about the resource 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. Data type Meta Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a rim: N/A
implicitRules	Σ ?!	0..1	uri	There are no (further) constraints on this element Element id Procedure.implicitRules Short description A set of rules under which this content was created 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. 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. Data type uri Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a
language		0..1	codeBinding	There are no (further) constraints on this element Element id Procedure.language Short description Language of the resource content Definition The base language in which the resource is written. 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). Data type code Binding A human language. CommonLanguages (preferred) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a
text		0..1	Narrative	There are no (further) constraints on this element Element id Procedure.text Short description Text summary of the resource, for human interpretation Alternate names narrative, html, xhtml, display 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. 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. Data type Narrative Constraints 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?
contained		0..*	Resource	There are no (further) constraints on this element Element id Procedure.contained Short description Contained, inline Resources Alternate names inline resources, anonymous resources, contained resources 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. 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. Data type Resource Mappings rim: Entity. Role, or Act rim: N/A
extension	I	0..*	Extension	There are no (further) constraints on this element Element id Procedure.extension Short description Additional content defined by implementations Alternate names extensions, user content 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. 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. Data type Extension Sliced: Unordered, Open, by url(Value) Extensions are always sliced by (at least) url Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ext-1: Must have either extensions or value[x], not both `extension.exists() != value.exists()` Mappings rim: n/a rim: N/A
modifierExtension	?! I	0..*	Extension	There are no (further) constraints on this element Element id Procedure.modifierExtension Short description Extensions that cannot be ignored Alternate names extensions, user content 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). 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. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. Data type Extension Sliced: Unordered, Open, by url(Value) Extensions are always sliced by (at least) url Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ext-1: Must have either extensions or value[x], not both `extension.exists() != value.exists()` Mappings rim: n/a rim: N/A
identifier	Σ	0..*	Identifier	There are no (further) constraints on this element Element id Procedure.identifier Short description External Identifiers for this procedure Definition Business identifiers assigned to this procedure by the performer or other systems which remain constant as the resource is updated and is propagated from server to server. Requirements Allows identification of the procedure as it is known by various participating systems and in a way that remains consistent across servers. Comments This is a business identifier, not a resource identifier (see discussion). 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 Person resource instances might share the same social insurance number. Data type Identifier Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a v2: CX / EI (occasionally, more often EI maps to a resource id or a URL) rim: II - The Identifier class is a little looser than the v3 type II because it allows URIs as well as registered OIDs or GUIDs. Also maps to Role[classCode=IDENT] servd: Identifier workflow: Event.identifier w5: FiveWs.identifier v2: Some combination of ORC-2 / ORC-3 / OBR-2 / OBR-3 / IPC-1 / IPC-2 / IPC-3 / IPC-4 rim: .id

Comments This might be an HTML page, PDF, etc. or could just be a non-resolvable URI identifier. Data type uri Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a workflow: Event.instantiatesUri rim: .outboundRelationship[typeCode=DEFN].target
basedOn	Σ I	0..*	Reference(CarePlan \| ServiceRequest)	There are no (further) constraints on this element Element id Procedure.basedOn Short description A request for this procedure Alternate names fulfills Definition A reference to a resource that contains details of the request for this procedure. 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. Data type Reference(CarePlan \| ServiceRequest) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ref-1: SHALL have a contained resource if a local reference is provided `reference.startsWith('#').not() or (reference.substring(1).trace('url') in %rootResource.contained.id.trace('ids'))` Mappings rim: n/a rim: The target of a resource reference is a RIM entry point (Act, Role, or Entity) workflow: Event.basedOn rim: .outboundRelationship[typeCode=FLFS].target[classCode=(various e.g. PROC, OBS, PCPR, ACT, moodCode=RQO].code
partOf	Σ I	0..*	Reference(Procedure \| Observation \| MedicationAdministration)	There are no (further) constraints on this element Element id Procedure.partOf Short description Part of referenced event Alternate names container Definition A larger event of which this particular procedure is a component or step. Comments The MedicationAdministration resource has a partOf reference to Procedure, but this is not a circular reference. For example, the anesthesia MedicationAdministration is part of the surgical Procedure (MedicationAdministration.partOf = Procedure). For example, the procedure to insert the IV port for an IV medication administration is part of the medication administration (Procedure.partOf = MedicationAdministration). Data type Reference(Procedure \| Observation \| MedicationAdministration) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ref-1: SHALL have a contained resource if a local reference is provided `reference.startsWith('#').not() or (reference.substring(1).trace('url') in %rootResource.contained.id.trace('ids'))` Mappings rim: n/a rim: The target of a resource reference is a RIM entry point (Act, Role, or Entity) workflow: Event.partOf rim: .inboundRelationship[typeCode=COMP].source[classCode=SBADM or PROC or OBS, moodCode=EVN]
status	S Σ ?!	1..1	codeBinding	Element id Procedure.status Short description A code specifying the state of the procedure. Definition A code specifying the state of the procedure. Generally, this will be the in-progress or completed state. 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. Data type code Binding A code specifying the state of the procedure. EventStatus (required) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a workflow: Event.status w5: FiveWs.status rim: statusCode
statusReason	Σ	0..1	CodeableConcept	There are no (further) constraints on this element Element id Procedure.statusReason Short description Reason for current status Alternate names Suspended Reason, Cancelled Reason Definition Captures the reason for the current state of the procedure. Comments This is generally only used for "exception" statuses such as "not-done", "suspended" or "aborted". The reason for performing the event at all is captured in reasonCode, not here. Data type CodeableConcept Binding A code that identifies the reason a procedure was not performed. ProcedureNotPerformedReason(SNOMED-CT) (example) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a v2: CE/CNE/CWE rim: CD orim: fhir:CodeableConcept rdfs:subClassOf dt:CD workflow: Event.statusReason rim: .reason.Observation.value
category	Σ	0..1	CodeableConcept	There are no (further) constraints on this element Element id Procedure.category Short description Classification of the procedure Definition A code that classifies the procedure for searching, sorting and display purposes (e.g. "Surgical Procedure"). 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. Data type CodeableConcept Binding A code that classifies a procedure for searching, sorting and display purposes. ProcedureCategoryCodes(SNOMEDCT) (example) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a v2: CE/CNE/CWE rim: CD orim: fhir:CodeableConcept rdfs:subClassOf dt:CD w5: FiveWs.class rim: .outboundRelationship[typeCode="COMP].target[classCode="LIST", moodCode="EVN"].code

Use text if the exact nature of the procedure cannot be coded (e.g. "Laparoscopic Appendectomy"). Requirements 0..1 to account for primarily narrative only resources. 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.

Alternate names patient Definition The person, animal or group on which the procedure was performed. 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. Data type Reference(Patient \| Group) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ref-1: SHALL have a contained resource if a local reference is provided `reference.startsWith('#').not() or (reference.substring(1).trace('url') in %rootResource.contained.id.trace('ids'))` Mappings rim: n/a rim: The target of a resource reference is a RIM entry point (Act, Role, or Entity) workflow: Event.subject w5: FiveWs.subject[x] v2: PID-3 rim: .participation[typeCode=SBJ].role w5: FiveWs.subject

Data type Reference(Encounter) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ref-1: SHALL have a contained resource if a local reference is provided `reference.startsWith('#').not() or (reference.substring(1).trace('url') in %rootResource.contained.id.trace('ids'))` Mappings rim: n/a rim: The target of a resource reference is a RIM entry point (Act, Role, or Entity) workflow: Event.context w5: FiveWs.context v2: PV1-19 rim: .inboundRelationship[typeCode=COMP].source[classCode=ENC, moodCode=EVN]
performed[x]	S Σ	0..1		Element id Procedure.performed[x] Short description When the procedure was performed. Definition Estimated or actual date, date-time, period, or age when the procedure was performed. Allows a period to support complex procedures that span more than one date, and also allows for the length of the procedure to be captured. Comments Age is generally used when the patient reports an age at which the procedure was performed. Range is generally used when the patient reports an age range when the procedure was performed, such as sometime between 20-25 years old. dateTime supports a range of precision due to some procedures being reported as past procedures that might not have millisecond precision while other procedures performed and documented during the encounter might have more precise UTC timestamps with timezone. Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a workflow: Event.occurrence[x] w5: FiveWs.done[x] v2: OBR-7 rim: .effectiveTime

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.

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.

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.
Procedure.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	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.

Definition	The base language in which the resource is written.
Cardinality	0...1
Type	code
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).

Procedure.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.

Comments	This is a business identifier, not a resource identifier (see discussion). 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.
