0. DocumentReference
Definition

A reference to a document of any kind for any purpose. Provides metadata about the document so that the document can be discovered and managed. The scope of a document is any seralized object with a mime-type, so includes formal patient centric documents (CDA), cliical notes, scanned paper, and non-patient specific documents like policy text.

ShortA reference to a document
Comments

Usually, this is used for documents other than those defined by FHIR.

2. DocumentReference.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. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.

ShortA set of rules under which this content was created
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.

4. DocumentReference.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 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).

ShortExtensions that cannot be ignored
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.

Control0..0*
This element is affected by the following invariants: ele-1
TypeExtension
Is Modifiertrue because Modifier extensions are expected to modify the meaning or interpretation of the resource that contains them
Summaryfalse
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

      Das Attribut typeCode ist gemäß IHE XDS zwingend gefordert und kann zusätzlich zu (bzw. zusammen mit) dem classCode zur genaueren Klassifizierung des Dokuments genutzt werden, z.B. kann ein Dokument mit classCode 'Befundberichte' durch den typeCode als 'Pathologiebefundbericht' oder als 'Ergebnisse bildgebender Diagnostik' gekennzeichnet werden. Das Attribut typeCode stellt keine Spezialisierung von classCode dar. Somit kann ein bestimmter typeCode mit verschiedenen classCodes zur Beschreibung unterschiedlicher Dokumente kombiniert werden. Zum Beispiel haben ein Röntgenbild und der dazugehörige Radiologie-Befund den gleichen typeCode 'Ergebnisse bildgebender Diagnostik' aber zwei unterschiedliche classCodes, 'Bilddaten' bzw.'Befundberichte'. Daraus folgt, dass ein Dokument sowohl einem classCode als auch einem typeCode explizit zugeordnet werden muss; die Zuordnung zu einem typeCode allein reicht nicht aus, weil hierüber kein implizites Mapping auf einen einzigen 'übergeordneten' classCode möglich ist.

      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.

      ShortLogical reference, when literal reference is not known
      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).

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.

      ShortLogical reference, when literal reference is not known
      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).

      Comments

      Der Confidentiality Code drückt die Vertraulichkeitsstufe des Dokuments aus. Die Vertraulichkeitsstufe ist üblicherweise die Einschätzung des Autors oder des Einstellenden wie schützenswert das Dokument ist. Die Einschätzung des Autors oder Erstellers sollte erhalten bleiben, auch wenn die des Betroffenen (d.h. des Patienten) davon abweicht. Das heißt, dass man dem Dokument mehrere ConfidentialityCodes zuordnen können sollte. Dies unterstützt IHE XDS auch. Daher enthält das deutsche Value Set neben Codes der Autoreneinschätzung explizite Codes zur Betroffeneneinschätzung, die aus einem separaten, dediziertem Codesystem stammen. Die Datenkategorie des Dokuments entsprechend der ePA Legal Policy ist ebenso Bestandteil dieser Liste.


      The confidentiality codes can carry multiple vocabulary items. HL7 has developed an understanding of security and privacy tags that might be desirable in a Document Sharing environment, called HL7 Healthcare Privacy and Security Classification System (HCS). The following specification is recommended but not mandated, as the vocabulary bindings are an administrative domain responsibility. The use of this method is up to the policy domain such as the XDS Affinity Domain or other Trust Domain where all parties including sender and recipients are trusted to appropriately tag and enforce.

      In the HL7 Healthcare Privacy and Security Classification (HCS) there are code systems specific to Confidentiality, Sensitivity, Integrity, and Handling Caveats. Some values would come from a local vocabulary as they are related to workflow roles and special projects.

      Definition

      May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions.

      Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

      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.

      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.

      Comments

      Die eventCode Liste wurde konzipiert, um den medizinischen Kontext von Dokumenten abzubilden. Jedem Dokument können beliebig viele eventCodes zugeordnet werden. Zum Beispiel kann ein OP-Bericht über die eventCodeList mit je einem kodierten Wert für die durchgeführte Prozedur (z.B. Blinddarmentfernung) und die vorliegende Erkrankung (z.B. Appendizitis) versehen werden. Dies ermöglicht die Suche nach Dokumenten, die mit einer bestimmten Prozedur oder Diagnose zusammenhängen. Über den medizinischen Kontext hinaus kann das Attribut auch allgemein zur Kontextualisierung und zur Inhaltszusammenfassung verwendet werden.


      An event can further specialize the act inherent in the type, such as where it is simply "Procedure Report" and the procedure was a "colonoscopy". If one or more event codes are included, they shall not conflict with the values inherent in the class or type elements as such a conflict would create an ambiguous situation.

      DocumentEntry.healthcareFacilityTypeCode repräsentiert die Art der Einrichtung, in der die Tätigkeit stattfand, die zur Erzeugung des Dokuments führte. Zum Beispiel sollten Dokumente, die während eines ambulanten Falls in einem Krankenhaus entstehen, mit dem healthcareFacilityTypeCode für 'Krankenhaus' gekennzeichnet werden. Dabei ist zu beachten, dass es sich nicht notwendigerweise um die Art der Einrichtung handelt, in der das Dokument erstellt wurde. Beispielsweise ist es bei teleradiologischer Befundung eines Röntgenbildes für den healthcareFacilityTypeCode unerheblich, ob der befundende Radiologe in einem Krankenhaus oder in einer radiologischen Praxis ansässig ist; für den healthcareFacilityTypeCode wird die Einrichtungsart der Untersuchungsstelle (in der das Gerät betrieben wird) herangezogen.

      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.

      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.

      Kennung des Patienten im Quellsystem (DocumentEntry.sourcePatientId)


      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.

      ShortKennung des Patienten im QuellsystemLogical reference, when literal reference is not known
      Comments

      n/a


      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).

      NoteThis is a business identifier, not a resource identifier (see discussion)

      Art des Dokuments (DocumentEntry.typeCode)

      ShortArt des Dokuments
      Comments

      Das Attribut typeCode ist gemäß IHE XDS zwingend gefordert und kann zusätzlich zu (bzw. zusammen mit) dem classCode zur genaueren Klassifizierung des Dokuments genutzt werden, z.B. kann ein Dokument mit classCode 'Befundberichte' durch den typeCode als 'Pathologiebefundbericht' oder als 'Ergebnisse bildgebender Diagnostik' gekennzeichnet werden. Das Attribut typeCode stellt keine Spezialisierung von classCode dar. Somit kann ein bestimmter typeCode mit verschiedenen classCodes zur Beschreibung unterschiedlicher Dokumente kombiniert werden. Zum Beispiel haben ein Röntgenbild und der dazugehörige Radiologie-Befund den gleichen typeCode 'Ergebnisse bildgebender Diagnostik' aber zwei unterschiedliche classCodes, 'Bilddaten' bzw.'Befundberichte'. Daraus folgt, dass ein Dokument sowohl einem classCode als auch einem typeCode explizit zugeordnet werden muss; die Zuordnung zu einem typeCode allein reicht nicht aus, weil hierüber kein implizites Mapping auf einen einzigen 'übergeordneten' classCode möglich ist.

      Der Confidentiality Code drückt die Vertraulichkeitsstufe des Dokuments aus. Die Vertraulichkeitsstufe ist üblicherweise die Einschätzung des Autors oder des Einstellenden wie schützenswert das Dokument ist. Die Einschätzung des Autors oder Erstellers sollte erhalten bleiben, auch wenn die des Betroffenen (d.h. des Patienten) davon abweicht. Das heißt, dass man dem Dokument mehrere ConfidentialityCodes zuordnen können sollte. Dies unterstützt IHE XDS auch. Daher enthält das deutsche Value Set neben Codes der Autoreneinschätzung explizite Codes zur Betroffeneneinschätzung, die aus einem separaten, dediziertem Codesystem stammen. Die Datenkategorie des Dokuments entsprechend der ePA Legal Policy ist ebenso Bestandteil dieser Liste.

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.

Das Attribut typeCode stellt keine Spezialisierung von classCode dar. Somit kann ein bestimmter typeCode mit verschiedenen classCodes zur Beschreibung unterschiedlicher Dokumente kombiniert werden. Zum Beispiel haben ein Röntgenbild und der dazugehörige Radiologie-Befund den gleichen typeCode 'Ergebnisse bildgebender Diagnostik' aber zwei unterschiedliche classCodes, 'Bilddaten' bzw.'Befundberichte'. Daraus folgt, dass ein Dokument sowohl einem classCode als auch einem typeCode explizit zugeordnet werden muss; die Zuordnung zu einem typeCode allein reicht nicht aus, weil hierüber kein implizites Mapping auf einen einzigen 'übergeordneten' classCode möglich ist.

                  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.

                  Das Attribut 'classCode' ist gemäß IHE XDS zwingend gefordert und erlaubt eine erste Klassifizierung der Dokumente in der XDS Document Registry in Dokumentenklassen, wie z.B. Briefe, Befundberichte oder Bilddaten. Die Wertemenge für diese Klassen sollte nicht zu detailliert sein, da im Attribut 'typeCode' eine weitere, verfeinerte Beschreibung der Dokumente erfolgt, die allerdings keine Spezialisierung des 'classCode' darstellen muss.

                      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.

                        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.

                        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.

                        ShortLogical reference, when literal reference is not known
                        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).

                        NoteThis is a business identifier, not a resource identifier (see discussion)

                          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.

                          ShortLogical reference, when literal reference is not known
                          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).

                          NoteThis is a business identifier, not a resource identifier (see discussion)

                          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.

                            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.

                              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.

Die Vertraulichkeitsstufe ist üblicherweise die Einschätzung des Autors oder des Einstellenden wie schützenswert das Dokument ist. Die Einschätzung des Autors oder Erstellers sollte erhalten bleiben, auch wenn die des Betroffenen (d.h. des Patienten) davon abweicht. Das heißt, dass man dem Dokument mehrere ConfidentialityCodes zuordnen können sollte. Dies unterstützt IHE XDS auch. Daher enthält das deutsche Value Set neben Codes der Autoreneinschätzung explizite Codes zur Betroffeneneinschätzung, die aus einem separaten, dediziertem Codesystem stammen. Die Datenkategorie des Dokuments entsprechend der ePA Legal Policy ist ebenso Bestandteil dieser Liste.

Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged.

                                  Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.

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.

                                        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.

Blinddarmentfernung) und die vorliegende Erkrankung (z.B. Appendizitis) versehen werden. Dies ermöglicht die Suche nach Dokumenten, die mit einer bestimmten Prozedur oder Diagnose zusammenhängen. Über den medizinischen Kontext hinaus kann das Attribut auch allgemein zur Kontextualisierung und zur Inhaltszusammenfassung verwendet werden.

                                            Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.

                                            A Period specifies a range of time; the context of use will specify whether the entire range applies (e.g. "the patient was an inpatient of the hospital for this time range") or one value from the range applies (e.g. "give to the patient between these two times").

                                            Period is not used for a duration (a measure of elapsed time). See Duration.

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.

Zum Beispiel sollten Dokumente, die während eines ambulanten Falls in einem Krankenhaus entstehen, mit dem healthcareFacilityTypeCode für 'Krankenhaus' gekennzeichnet werden. Dabei ist zu beachten, dass es sich nicht notwendigerweise um die Art der Einrichtung handelt, in der das Dokument erstellt wurde. Beispielsweise ist es bei teleradiologischer Befundung eines Röntgenbildes für den healthcareFacilityTypeCode unerheblich, ob der befundende Radiologe in einem Krankenhaus oder in einer radiologischen Praxis ansässig ist; für den healthcareFacilityTypeCode wird die Einrichtungsart der Untersuchungsstelle (in der das Gerät betrieben wird) herangezogen.

Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged.

                                                  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.

                                                      The version of the code system which was used when choosing this code. Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged.

                                                      Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.

                                                        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).

                                                        ShortType the reference refers to (e.g. "Patient")

                                                        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.

                                                        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.
