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.

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

bedingtes Pflichtfeld/bedingtes MS: Alle von einem Server bereitgestellten Ressourcen MÜSSEN über eine id verfügen. Von Clients erzeugte Ressourcen, die im Kontext einer CREATE-Interaktion übermittelt werden, MÜSSEN NICHT über eine idverfügen.

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.

Begründung Constraint: In ISiK existiert kein Use-Case für dieses Element. Da es sich um ein Modifying Element handelt, wird es daher ausgeschlossen. Darüber hinaus werden die Regeln als URI vorgehalten. Dies führt dazu, dass sich hinter der URI eine beliebige Menge an Regeln befinden kann; wodurch nicht sichergestellt werden kann, dass alle Clients die Regeln korrekt interpretieren können.

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).

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.

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

A code specifying the state of the procedure.

A code that classifies the procedure for searching, sorting and display purposes (e.g. "Surgical Procedure").

Die Kategorisierung erfolgt vorzugsweise auf Basis von SNOMED CT. Für OPS-codierte Prozeduren MUSS die Kategorie angegeben werden: Sie kann ermittelt werden, indem das erste Zeichen des OPS-Codes mit Hilfe einer ConceptMap auf die zutreffende SNOMED-Kategorie gemappt wird.

A code that classifies a procedure for searching, sorting and display purposes.

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.

A reference to a code defined by a terminology system.

Hinweis EHDS: In der HL7 Europe HDR Spezifikation ist ein Binding von Snomed-CT mit der Stärke preferred gesetzt. Dies schließt sich nicht mit der hier vorgenommenen Profilierung aus, und auch eine reine OPS Abbildung spricht nicht gegen diese Anforderung. Allerdings möchten wir darauf hinweisen, dass es in Zukunft möglicherweise sinnvoll sein könnte, die Nutzung von SNOMED-CT Kodierung zur Darstellung einer Prozedur zu nutzen, um die Interoperabilität mit dem HDR zu erhöhen.

Need to be unambiguous about the source of the definition of the symbol.

Bie Verwendung von OPS ist die Angabe der Version zwingend erforderlich. Hierdurch wird der Tatsache Rechnung getragen, dass jede der jährlich neu erscheinenden Fassung von OPS ein neues Codesystem darstellt.

Begründung Pflichtfeld: Bei Verwendung von OPS ist die Angabe der Version zwingend erforderlich. Hierdurch wird der Tatsache Rechnung getragen, dass jede der jährlich neu erscheinenden Fassung von OPS ein neues Codesystem darstellt.

A symbol in syntax defined by the system. The symbol may be a predefined code or an expression in a syntax defined by the coding system (e.g. post-coordination).

Hier ist der OPS-Code ohne jegliche Zusatzkennzeichen (z.B. Seitenlokalisation) oder Versionsnummern anzugeben.

Need to refer to a particular code in the system.

A reference to a code defined by a terminology system.

Hintergrund und Begründung zum Must-Support: Das BfArM hat ein 'Zielbild für eine semantische Strategie' (https://www.bfarm.de/DE/Kodiersysteme/Services/Terminologieserver/Semantik-Strategie/_node.html) verfasst, in dem die Nutzung von international gängigen Basis-Terminologien vorgestellt wird. Dort wird als grundlegende Position dargestellt, dass basierend auf einer Basisterminologie weitere Use Cases bedient werden sollen. Bei Prozeduren wäre das damit eine klinische Dokumentation mit SNOMED CT als internationalem Kodiersystem und einer Ableitung davon zum OPS. Dies ist insbesondere auch wichtig für den Datentransfer in den European Health Data Space, in dem der OPS keine Rolle spielen wird.

Allows for alternative encodings within a code system, and translations to other code systems.

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.

Die freitextliche Beschreibung kann ergänzend oder anstelle einer codierten Angabe der Prozedur erfolgen.

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.

The person, animal or group on which the procedure was performed.

Begründung Must-Support: Ein Patientenbezug der Prozedur MUSS stets zum Zwecke der Nachvollziehbarkeit und Datenintegrität vorliegen.

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.

Begründung MS: Die Verlinkung auf eine Patienten-Ressource dient der technischen Zuordnung der Dokumentation zu einem Patienten und ermöglicht wichtige API-Funktionen wie verkettete Suche, (Reverse-)Include etc. Im ISik Kontext MUSS die referenzierte Ressource konform zu ISiKPatient sein. Jenseits von ISiK KÖNNEN weitere Instanzen mit anderen Profilen referenziert werden.

The Encounter during which this Procedure was created or performed or to which the creation of this record is tightly associated.

Begründung Must-Support: Ein Aufenthaltsbezug der Prozedur MUSS stets zum Zwecke der Nachvollziehbarkeit und Datenintegrität vorliegen.

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.

Begründung Pflichtfeld: Die Verlinkung auf eine Encounter-Ressource dient der technischen Zuordnung der Dokumentation zu einem Aufenthalt und ermöglicht wichtige API-Funktionen wie verkettete Suche, (Reverse-)Include etc. Im ISik Kontext MUSS die referenzierte Ressource konform zu ISiKKontaktGesundheitseinrichtung sein. Jenseits von ISiK KÖNNEN weitere Instanzen mit anderen Profilen referenziert werden.

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.

Es muss mindestens entweder ein (partielles) Durchführungsdatum oder der Beginn des Durchführungszeitraumes angegeben werden. Begründung Pflichtfeld: Die zeitliche Einordnung einer Prozedur ist in vielen Fällen maßgeblich für deren medizinische Relevanz.

Any other notes and comments about the procedure.

Ergänzende Hinweise und Anmerkungen zur Prozedur

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.

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

bedingtes Pflichtfeld/bedingtes MS: Alle von einem Server bereitgestellten Ressourcen MÜSSEN über eine id verfügen. Von Clients erzeugte Ressourcen, die im Kontext einer CREATE-Interaktion übermittelt werden, MÜSSEN NICHT über eine idverfügen.

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.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

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.

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.

The version specific identifier, as it appears in the version portion of the URL. This value changes when the resource is created, updated, or deleted.

Alle von einem Server bereitgestellten Ressourcen SOLLEN über eine versionID verfügen. Von Clients erzeugte Ressourcen, die im Kontext einer CREATE-Interaktion übermittelt werden, MÜSSEN NICHT über eine versionIDverfügen.

When the resource last changed - e.g. when the version changed.

Alle von einem Server bereitgestellten Ressourcen SOLLEN über ein lastUpdate verfügen. Von Clients erzeugte Ressourcen, die im Kontext einer CREATE-Interaktion übermittelt werden, MÜSSEN NICHT über ein lastUpdateverfügen.

A uri that identifies the source system of the resource. This provides a minimal amount of Provenance information that can be used to track or differentiate the source of information in the resource. The source may identify another FHIR server, document, message, database, etc.

In the provenance resource, this corresponds to Provenance.entity.what[x]. The exact use of the source (and the implied Provenance.entity.role) is left to implementer discretion. Only one nominated source is allowed; for additional provenance details, a full Provenance resource should be used.

This element can be used to indicate where the current master source of a resource that has a canonical URL if the resource is no longer hosted at the canonical URL.

A list of profiles (references to StructureDefinition resources) that this resource claims to conform to. The URL is a reference to StructureDefinition.url.

It is up to the server and/or other infrastructure of policy to determine whether/how these claims are verified and/or updated over time. The list of profile URLs is a set.

Security labels applied to this resource. These tags connect specific resources to the overall security policy and infrastructure.

The security labels can be updated without changing the stated version of the resource. The list of security labels is a set. Uniqueness is based the system/code, and version and display are ignored.

Security Labels from the Healthcare Privacy and Security Classification System.

Tags applied to this resource. Tags are intended to be used to identify and relate resources to process and workflow, and applications are not required to consider the tags when interpreting the meaning of a resource.

The tags can be updated without changing the stated version of the resource. The list of tags is a set. Uniqueness is based the system/code, and version and display are ignored.

Codes that represent various types of tags, commonly workflow-related; e.g. "Needs review by Dr. Jones".

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.

Begründung Constraint: In ISiK existiert kein Use-Case für dieses Element. Da es sich um ein Modifying Element handelt, wird es daher ausgeschlossen. Darüber hinaus werden die Regeln als URI vorgehalten. Dies führt dazu, dass sich hinter der URI eine beliebige Menge an Regeln befinden kann; wodurch nicht sichergestellt werden kann, dass alle Clients die Regeln korrekt interpretieren können.

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).

A human language.

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.

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.

This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

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.

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.

Allows identification of the procedure as it is known by various participating systems and in a way that remains consistent across servers.

The URL pointing to a FHIR-defined protocol, guideline, order set or other definition that is adhered to in whole or in part by this Procedure.

The URL pointing to an externally maintained protocol, guideline, order set or other definition that is adhered to in whole or in part by this Procedure.

This might be an HTML page, PDF, etc. or could just be a non-resolvable URI identifier.

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

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

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).

Need to refer to a particular code in the system.

A representation of the meaning of the code in the system, following the rules of the system.

Need to be able to carry a human-readable meaning of the code for readers that do not know the system.

Indicates that this coding was chosen by a user directly - e.g. off a pick list of available items (codes or displays).

Amongst a set of alternatives, a directly chosen code is the most appropriate starting point for new translations. There is some ambiguity about what exactly 'directly chosen' implies, and trading partner agreement may be needed to clarify the use of this element and its consequences more completely.

This has been identified as a clinical safety criterium - that this exact system/code pair was chosen explicitly, rather than inferred by the system based on some rules or language processing.

A reference to a code defined by a terminology system.

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.

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.

Begründung MS: Die Verlinkung auf eine Patienten-Ressource dient der technischen Zuordnung der Dokumentation zu einem Patienten und ermöglicht wichtige API-Funktionen wie verkettete Suche, (Reverse-)Include etc. Im ISik Kontext MUSS die referenzierte Ressource konform zu ISiKPatient sein. Jenseits von ISiK KÖNNEN weitere Instanzen mit anderen Profilen referenziert werden.

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).

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.

Aa resource (or, for logical models, the URI of the logical model).

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.

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).

Plain text narrative that identifies the resource in addition to the resource reference.

This is generally not the same as the Resource.text of the referenced resource. The purpose is to identify what's being referenced, not to fully describe it.

The Encounter during which this Procedure was created or performed or to which the creation of this record is tightly associated.

Begründung Must-Support: Ein Aufenthaltsbezug der Prozedur MUSS stets zum Zwecke der Nachvollziehbarkeit und Datenintegrität vorliegen.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

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.

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.

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.

Begründung Pflichtfeld: Die Verlinkung auf eine Encounter-Ressource dient der technischen Zuordnung der Dokumentation zu einem Aufenthalt und ermöglicht wichtige API-Funktionen wie verkettete Suche, (Reverse-)Include etc. Im ISik Kontext MUSS die referenzierte Ressource konform zu ISiKKontaktGesundheitseinrichtung sein. Jenseits von ISiK KÖNNEN weitere Instanzen mit anderen Profilen referenziert werden.

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).

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.

Aa resource (or, for logical models, the URI of the logical model).

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.

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.

This is generally not the same as the Resource.text of the referenced resource. The purpose is to identify what's being referenced, not to fully describe it.

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.

Es muss mindestens entweder ein (partielles) Durchführungsdatum oder der Beginn des Durchführungszeitraumes angegeben werden. Begründung Pflichtfeld: Die zeitliche Einordnung einer Prozedur ist in vielen Fällen maßgeblich für deren medizinische Relevanz.

Individual who recorded the record and takes responsibility for its content.

Individual who is making the procedure statement.

Limited to "real" people rather than equipment.

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 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.

Distinguishes the type of involvement of the performer in the procedure. For example, surgeon, anaesthetist, endoscopist.

A code that identifies the role of a performer of the procedure.

Allows disambiguation of the types of involvement of different performers.

The practitioner who was involved in the procedure.

A reference to Device supports use cases, such as pacemakers.

The organization the device or practitioner was acting on behalf of.

Practitioners and Devices can be associated with multiple organizations. This element indicates which organization they were acting on behalf of when performing the action.

The location where the procedure actually happened. E.g. a newborn at home, a tracheostomy at a restaurant.

Ties a procedure to where the records are likely kept.

The coded reason why the procedure was performed. This may be a coded entity of some type, or may simply be present as text.

Use Procedure.reasonCode when a code sufficiently describes the reason. Use Procedure.reasonReference when referencing a resource, which allows more information to be conveyed, such as onset date. Procedure.reasonCode and Procedure.reasonReference are not meant to be duplicative. For a single reason, either Procedure.reasonCode or Procedure.reasonReference can be used. Procedure.reasonCode may be a summary code, or Procedure.reasonReference may be used to reference a very precise definition of the reason using Condition | Observation | Procedure | DiagnosticReport | DocumentReference. Both Procedure.reasonCode and Procedure.reasonReference can be used if they are describing different reasons for the procedure.

A code that identifies the reason a procedure is required.

The justification of why the procedure was performed.

It is possible for a procedure to be a reason (such as C-Section) for another procedure (such as an epidural). Other examples include endoscopy for dilatation and biopsy (a combination of diagnostic and therapeutic use). Use Procedure.reasonCode when a code sufficiently describes the reason. Use Procedure.reasonReference when referencing a resource, which allows more information to be conveyed, such as onset date. Procedure.reasonCode and Procedure.reasonReference are not meant to be duplicative. For a single reason, either Procedure.reasonCode or Procedure.reasonReference can be used. Procedure.reasonCode may be a summary code, or Procedure.reasonReference may be used to reference a very precise definition of the reason using Condition | Observation | Procedure | DiagnosticReport | DocumentReference. Both Procedure.reasonCode and Procedure.reasonReference can be used if they are describing different reasons for the procedure.

Detailed and structured anatomical location information. Multiple locations are allowed - e.g. multiple punch biopsies of a lesion.

If the use case requires attributes from the BodySite resource (e.g. to identify and track separately) then use the standard extension procedure-targetbodystructure.

Codes describing anatomical locations. May include laterality.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

Record details about the anatomical location of a specimen or body part. This resource may be used when a coded concept does not provide the necessary detail needed for the use case.

Im Kontext des Allingments mit dem EHDS und den damit verbundenen Spezifikationen von HL7 Europe wurde diese Extenion hinzugefügt. Es besteht aber noch keine Must-Support Anforderung, da die Abbildung der Lateralität noch in der Diskussion ist und somit keine klare Vorgabe für die Nutzung der Extension gegeben werden kann. Sobald dies geklärt ist, wird die Anforderung entsprechend angepasst. Eine referenzierte BodyStructure-Ressource sollte valide gegen bodyStructure-eu-core sein.

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.

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.

The outcome of the procedure - did it resolve the reasons for the procedure being performed?

If outcome contains narrative text only, it can be captured using the CodeableConcept.text.

An outcome of a procedure - whether it was resolved or otherwise.

This could be a histology result, pathology report, surgical report, etc.

There could potentially be multiple reports - e.g. if this was a procedure which took multiple biopsies resulting in a number of anatomical pathology reports.

Any complications that occurred during the procedure, or in the immediate post-performance period. These are generally tracked separately from the notes, which will typically describe the procedure itself rather than any 'post procedure' issues.

If complications are only expressed by the narrative text, they can be captured using the CodeableConcept.text.

Codes describing complications that resulted from a procedure.

Any complications that occurred during the procedure, or in the immediate post-performance period.

This is used to document a condition that is a result of the procedure, not the condition that was the reason for the procedure.

If the procedure required specific follow up - e.g. removal of sutures. The follow up may be represented as a simple note or could potentially be more complex, in which case the CarePlan resource can be used.

Specific follow up required for a procedure e.g. removal of sutures.

Any other notes and comments about the procedure.
