'PS-CA:BC Patient Summary FHIR Implementation Guide'

Profile: Procedure

Definition

The Procedure Resource is an action that is or was performed on or for a patient. This can be a physical intervention like an operation, or less invasive interventions like long term services, counseling, or hypnotherapy.

This resource is used to record the details of current and historical procedures performed on or for a patient. A procedure is an activity that is performed on, with, or for a patient as part of the provision of care. Examples include surgical procedures, diagnostic procedures, endoscopic procedures, biopsies, counseling, 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 the patient themselves.

This resource provides summary information about the occurrence of the procedure and is not intended to provide real-time snapshots of a procedure as it unfolds, though for long-running procedures such as psychotherapy, it could represent summary level information about overall progress. The creation of a resource to support detailed real-time procedure information awaits the identification of a specific implementation use-case to share such information.

Context

The Procedure (PS-CA) profile represents the constraints applied to the Procedure resource by the PS-CA project, which is informed by the constraints of the Procedure IPS-UV profile and the Canadian Baseline Profile to allow for cross-border and cross-jurisdiction sharing of History of Procedure information.

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.

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.

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

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	There are no (further) constraints on this element Element id Procedure.status Short description preparation \| in-progress \| not-done \| on-hold \| stopped \| completed \| entered-in-error \| unknown 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.

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.

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.

code	S Σ	1..1	CodeableConceptPSCABinding	Element id Procedure.code Short description Concept - reference to a terminology or just text Alternate names type Definition Identification of the procedure or recording of "absence of relevant procedures" or of "procedures unknown". Requirements 0..1 to account for primarily narrative only resources. Comments Many Canadian implementations use codes from either SNOMED CT and the SNOMED CT Canada Extension to describe this concept, while others may still be using localized code systems or text descriptions. The Procedures - IPS ValueSet contains codes that are subsumed within the SNOMED CT CA ProcedureCode ValueSet that is preferred for this element. Future releases of PS-CA may require use of coded entries. In this release, however, implementations that support codings are encouraged to send the codings for codeable concepts if they are available. Consistent with FHIR best practice, receivers should not produce failures or rejections if codings are received. Vendors should expect that some jurisdictions may further constrain support of this element within the context of their own jurisdictional content. Data type CodeableConceptPSCA Binding A code to identify a specific procedure . ProcedureCode (preferred) Additional bindings: CCIAllCode (candidate) Any code from CCI. While not the preferred terminology for broader pan-Canadian exchange use cases, this additional binding is surfaced to socialize the value sets that may be more commonly in use. Where multiple codings can be supplied, it is encouraged to supply the original coding alongside the pan-Canadian preferred terminology. ICD9CMAllCode (candidate) Any code from ICD-9 CM.

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.

reference	S Σ I	1..1	string	There are no (further) constraints on this element Element id Procedure.subject.reference Short description Literal reference, Relative, internal or absolute URL Definition 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 Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries. Absolute URLs do not need to point to a FHIR RESTful server, though this is the preferred approach. If the URL conforms to the structure "/[type]/[id]" then it should be assumed that the reference is to a FHIR RESTful server.

type	Σ	0..1	uriBinding	There are no (further) constraints on this element Element id Procedure.subject.type Short description Type the reference refers to (e.g. "Patient") Definition The expected type of the target of the reference. If both Reference.type and Reference.reference are populated and Reference.reference is a FHIR URL, both SHALL be consistent. The type is the Canonical URL of Resource Definition that is the type this reference refers to. References are URLs that are relative to http://hl7.org/fhir/StructureDefinition/ e.g. "Patient" is a reference to http://hl7.org/fhir/StructureDefinition/Patient. Absolute URLs are only allowed for logical models (and can only be used in references in logical models, not resources). Comments This element is used to indicate the type of the target of the reference. This may be used which ever of the other elements are populated (or not). In some cases, the type of the target may be determined by inspection of the reference (e.g. a RESTful URL) or by resolving the target of the reference; if both the type and a reference is provided, the reference SHALL resolve to a resource of the same type as that specified. Data type uri Binding Aa resource (or, for logical models, the URI of the logical model). ResourceType (extensible) 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
identifier	Σ	0..1	Identifier	There are no (further) constraints on this element Element id Procedure.subject.identifier Short description Logical reference, when literal reference is not known Definition An identifier for the target resource. This is used when there is no way to reference the other resource directly, either because the entity it represents is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference. Comments When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it. Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference. For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation\|DiagnosticReport). One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any).

performed[x]	S Σ	1..1		There are no (further) constraints on this element 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.

BC-specific Notes

Procedures (Composition.section:sectionProceduresHx)

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.

Procedure.code

Definition: Identification of the procedure or recording of "absence of relevant procedures" or of "procedures unknown".

Comments: Must Support and Required.

Procedure.performed[x].DateTime

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: Must Support and Required. Date elements are displayed in the format YYYY/MM/DD. There is a stipulation that Procedures entries must be sorted based on their Performed Dates in descending chronological order, such that entries with the most recent performed dates are positioned at the top, while older ones are placed at the bottom.

Procedure.status

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

Comments: Must Support and Required. This element includes one value: Confirmed, which is a fixed value at a system level. This field need not be shown at the UI level and is currently not planned to be shown in the PS-CA:BC Patient Summary.

Procedure.section-note

Definition: Any other notes and comments about the procedure.

Comments: Optional with multiples value. This is a Free Text string element at Each Entry, which can be utilized to include additional information regarding each Procedure entry.
