Implementierungsleitfaden ISiK-Basismodul (4.0.1)

ISiKCodeSystem

Dieses Profil beschreibt die maschinenlesbare Repräsentation von system-spezifischen Kodierungen in ISiK-Szenarien.

Motivation

ISiK erlaubt in diversen Kontexten die Erweiterung der Kodierung durch Krankenhaus-/System-interne Kodierungen. Das Profil ISiKKatalog (CodeSystem) als Profil erlaubt die Repräsentation der dazugehörigen Codes und Display-Werte.

Eine maschinenlesbare Repräsentation dieser Kodierungen erlaubt es Clients, dazugehörige Anzeigetext und Definitionen zu verarbeiten.

Ein Codesystem eignet sich auch dazu, auf dessen Basis definierte ValueSets zu expandieren. Da ISiKValueSet expandierte Valuesets vorsieht, ist eine dynamische Expansion in der Regel nicht erforderlich. Darüber hinausgehend ist ein Use Case im Kontext der Katalogabfrage folgender: Ein Client möchte eine Expansion neu generieren (z.B. mit anderen Expansionen-Parametern), um das ValueSet beispielsweise in einer anderen Sprache auszugeben.

ISiKCodeSystem (CodeSystem)	I		CodeSystem	There are no (further) constraints on this element Element id CodeSystem Short description Declares the existence of and describes a code system or code system supplement Definition The CodeSystem resource is used to declare the existence of and describe a code system or code system supplement and its key properties, and optionally define a part or all of its content. Data type CodeSystem Constraints dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources `contained.contained.empty()` dom-4: If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated `contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()` dom-3: If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource `contained.where((('#'+id in (%resource.descendants().reference \| %resource.descendants().as(canonical) \| %resource.descendants().as(uri) \| %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(canonical) = '#').exists()).not()).trace('unmatched', id).empty()` dom-6: A resource should have narrative for robust management text.`div`.exists() dom-5: If a resource is contained in another resource, it SHALL NOT have a security label `contained.meta.security.empty()` csd-1: Within a code system definition, all the codes SHALL be unique `concept.code.combine($this.descendants().concept.code).isDistinct()` csd-0: Name should be usable as an identifier for the module by machine processing applications such as code generation `name.matches('[A-Z]([A-Za-z0-9_]){0,254}')` Mappings rim: Entity. Role, or Act rim: N/A
id	Σ	0..1	string	There are no (further) constraints on this element Element id CodeSystem.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 CodeSystem.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 CodeSystem.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 CodeSystem.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 CodeSystem.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 CodeSystem.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 CodeSystem.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 CodeSystem.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.

url	S Σ	1..1	uri	Element id CodeSystem.url Short description Kanonische URL Definition An absolute URI that is used to identify this code system when it is referenced in a specification, model, design or an instance; also called its canonical identifier. This SHOULD be globally unique and SHOULD be a literal address at which at which an authoritative instance of this code system is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the code system is stored on different servers. This is used in Coding.system. Requirements Allows the code system to be referenced by a single globally unique identifier. Comments Bedeutung: Eindeutige Url zur Identifizierung des CodeSystems. Absolute Url sind zu bevorzugen. Hinweise: OIDs SOLLTEN als weitere Identifier des CodeSystems verwendet werden. In jedem Fall SOLLTE eine Canonical Url vergeben werden.

identifier	Σ	0..*	Identifier	There are no (further) constraints on this element Element id CodeSystem.identifier Short description Additional identifier for the code system (business identifier) Definition A formal identifier that is used to identify this code system when it is represented in other formats, or referenced in a specification, model, design or an instance. Requirements Allows externally provided and/or usable business identifiers to be easily associated with the module. Comments Typically, this is used for identifiers that can go in an HL7 V3 II (instance identifier) data type, and can then identify this code system outside of FHIR, where it is not possible to use the logical URI. Note that HL7 defines at least three identifiers for many of its code systems - the FHIR canonical URL, the OID and the V2 Table 0396 mnemonic code. Data type Identifier Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a v2: CX / EI (occasionally, more often EI maps to a resource id or a URL) rim: II - The Identifier class is a little looser than the v3 type II because it allows URIs as well as registered OIDs or GUIDs. Also maps to Role[classCode=IDENT] servd: Identifier workflow: Definition.identifier w5: FiveWs.identifier objimpl: no-gen-base
version	S Σ	1..1	string	Element id CodeSystem.version Short description Version Definition The identifier that is used to identify this version of the code system when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the code system author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence. This is used in Coding.version. Comments Bedeutung: Version des CodeSystems Hinweise: Jede Änderung des CodeSystems MUSS eine Änderung in der Version des CodeSystems und gebundenen ValueSets nach sich ziehen. Die Versionierung SOLLTE auf dem Konzept von Semantic Versioning basieren. Data type string Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a workflow: Definition.version w5: FiveWs.version
name	S Σ I	1..1	string	Element id CodeSystem.name Short description Name des Codesystems Definition A natural language name identifying the code system. This name should be usable as an identifier for the module by machine processing applications such as code generation. Requirements Support human navigation and code generation. Comments Bedeutung: Maschinenlesbarer Name des CodeSystems Hinweise: Der Constraint cps-0 ist hierbei zu beachten. Data type string Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a
title	Σ	0..1	string	There are no (further) constraints on this element Element id CodeSystem.title Short description Name for this code system (human friendly) Definition A short, descriptive, user-friendly title for the code system. Comments This name does not need to be machine-processing friendly and may contain punctuation, white-space, etc. Data type string Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a workflow: Definition.title
status	S Σ ?!	1..1	codeBinding	Element id CodeSystem.status Short description Status Definition The date (and optionally time) when the code system resource was created or revised. Comments Zeigt den aktuellen Status der Ressource an. WICHTIGER Hinweis für Implementierer: Alle server-seitigen Implementierungen MÜSSEN in der Lage sein, die systemintern möglichen Statuswerte korrekt in FHIR abzubilden, mindestens jedoch 'active' und 'retired''. Alle client-seitigen Implementierungen MÜSSEN in der Lage sein, sämtliche Status-Codes zu interpretieren und dem Anwender in angemessener Form darstellen zu können, beispielsweise durch Ausblenden/Durchstreichen von Ressourcen mit dem status `entered-in-error` und Ausgrauen von Ressourcen, die einen Plan- oder Entwurfs-Status haben.

experimental	Σ	0..1	boolean	There are no (further) constraints on this element Element id CodeSystem.experimental Short description For testing purposes, not real usage Definition A Boolean value to indicate that this code system is authored for testing purposes (or education/evaluation/marketing) and is not intended to be used for genuine usage. Requirements Enables experimental content to be developed following the same lifecycle that would be used for a production-level code system. Comments Allows filtering of code systems that are appropriate for use versus not.

date	Σ	0..1	dateTime	There are no (further) constraints on this element Element id CodeSystem.date Short description Date last changed Alternate names Revision Date Definition The date (and optionally time) when the code system was published. The date must change when the business version changes and it must change if the status code changes. In addition, it should change when the substantive content of the code system changes. Comments Note that this is not the same as the resource last-modified-date, since the resource may be a secondary representation of the code system. Additional specific dates may be added as extensions or be found by consulting Provenances associated with past versions of the resource. Data type dateTime Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a workflow: Definition.date w5: FiveWs.recorded
publisher	Σ	0..1	string	There are no (further) constraints on this element Element id CodeSystem.publisher Short description Name of the publisher (organization or individual) Definition The name of the organization or individual that published the code system. Requirements Helps establish the "authority/credibility" of the code system. May also allow for contact. Comments Usually an organization but may be an individual. The publisher (or steward) of the code system is the organization or individual primarily responsible for the maintenance and upkeep of the code system. This is not necessarily the same individual or organization that developed and initially authored the content. The publisher is the primary point of contact for questions or issues with the code system. This item SHOULD be populated unless the information is available from context.

description		0..1	markdown	There are no (further) constraints on this element Element id CodeSystem.description Short description Natural language description of the code system Alternate names Scope, Purpose Definition A free text natural language description of the code system from a consumer's perspective. Comments This description can be used to capture details such as why the code system was built, comments about misuse, instructions for clinical use and interpretation, literature references, examples from the paper world, etc. It is not a rendering of the code system as conveyed in the 'text' field of the resource itself. This item SHOULD be populated unless the information is available from context (e.g. the language of the code system is presumed to be the predominant language in the place the code system was created).

These contexts may be general categories (gender, age, ...) or may be references to specific programs (insurance plans, studies, ...) and may be used to assist with indexing and searching for appropriate code system instances. Requirements Assist in searching for appropriate content. Comments When multiple useContexts are specified, there is no expectation that all or any of the contexts apply.

purpose		0..1	markdown	There are no (further) constraints on this element Element id CodeSystem.purpose Short description Why this code system is defined Definition Explanation of why this code system is needed and why it has been designed as it has. Comments This element does not describe the usage of the code system. Instead, it provides traceability of ''why'' the resource is either needed or ''why'' it is defined as it is. This may be used to point to source materials or specifications that drove the structure of this code system.

copyright		0..1	markdown	There are no (further) constraints on this element Element id CodeSystem.copyright Short description Use and/or publishing restrictions Alternate names License, Restrictions Definition A copyright statement relating to the code system and/or its contents. Copyright statements are generally legal restrictions on the use and publishing of the code system. Requirements Consumers must be able to determine any legal restrictions on the use of the code system and/or its content. Comments Systems are not required to have markdown support, so the text should be readable without markdown processing. The markdown syntax is GFM - see https://github.github.com/gfm/ Sometimes, the copyright differs between the code system and the codes that are included. The copyright statement should clearly differentiate between these when required. Sometimes, the copyright differs between the code system and the codes that are included.

caseSensitive	Σ	0..1	boolean	There are no (further) constraints on this element Element id CodeSystem.caseSensitive Short description If code comparison is case sensitive Definition If code comparison is case sensitive when codes within this system are compared to each other. Comments If this value is missing, then it is not specified whether a code system is case sensitive or not. When the rule is not known, Postel's law should be followed: produce codes with the correct case, and accept codes in any case. This element is primarily provided to support validation software.

hierarchyMeaning	Σ	0..1	codeBinding	There are no (further) constraints on this element Element id CodeSystem.hierarchyMeaning Short description grouped-by \| is-a \| part-of \| classified-with Definition The meaning of the hierarchy of concepts as represented in this resource. Comments Note that other representations might have a different hierarchy or none at all, and represent the information using properties. Data type code Binding The meaning of the hierarchy of concepts in a code system. CodeSystemHierarchyMeaning (required) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a
compositional	Σ	0..1	boolean	There are no (further) constraints on this element Element id CodeSystem.compositional Short description If code system defines a compositional grammar Alternate names grammar Definition The code system defines a compositional (post-coordination) grammar. Comments Note that the code system resource does not define what the compositional grammar is, only whether or not there is one. Data type boolean Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a
versionNeeded	Σ	0..1	boolean	There are no (further) constraints on this element Element id CodeSystem.versionNeeded Short description If definitions are not stable Definition This flag is used to signify that the code system does not commit to concept permanence across versions. If true, a version must be specified when referencing this code system. Comments Best practice is that code systems do not redefine concepts, or that if concepts are redefined, a new code system definition is created. But this is not always possible, so some code systems may be defined as 'versionNeeded'. Most code systems occasionally refine the displays defined for concepts between versions. Contexts in which the concept display values are validated may require that the version be specified for some code systems irrespective of the value of this property.

filter	Σ	0..*	BackboneElement	There are no (further) constraints on this element Element id CodeSystem.filter Short description Filter that can be used in a value set Definition A filter that can be used in a value set compose statement when selecting concepts using a filter. Comments Note that filters defined in code systems usually require custom code on the part of any terminology engine that will make them available for use in value set filters. For this reason, they are generally only seen in high value published terminologies.

Interaktionen

Interaktion	Verbindlichkeit
read	MAY
search-type	MAY

Parameter	Typ	Verbindlichkeit	Hinweise
_id	token	SHALL	Beispiel: `GET [base]/[Resourcetype]?_id=103270` Anwendungshinweis: Der Parameter `_id` wird selten alleinstehend verwendet, da sich zum Abruf einer Ressource anhand der `id` die `READ`-Interaktion besser anbietet. Der Parameter kann jedoch verwendet werden, um den Abruf einer Ressource bspw. mit einem `_include` weiterer Ressourcen zu verbinden, z.B. zum Abruf eines Encounters in Verbindung mit dem zugehörigen Patienten: `GET [base]/Encounter?_id=103270&_include=Encounter:patient` Weitere Details siehe FHIR-Kernspezifikation, Abschnitt Parameters for all resources. Dieser Suchparameter ist für die Umsetzung des IHE PDQm Profils verpflichtend.
_tag	token	SHALL	Beispiel: `GET [base]/[Resourcetype]?_tag=https://example.org/codes\|needs-review` Anwendungshinweis: Weitere Details siehe FHIR-Kernspezifikation, Abschnitt Parameters for all resources sowie Abschnitt Tags.
_count	number	SHALL	Beispiel: `GET [base]/[Resourcetype]?_count=100` Anwendungshinweis: Weitere Details siehe FHIR-Kernspezifikation, Abschnitt Page Count.
_has	string	MAY	Beispiel: Suche nach allen Patienten, die eine Observation mit dem Code '1234-5' haben `GET [base]/Patient?_has:Observation:patient:code=1234-5` Beispiel: Suche nach allen Encountern, bei denen die Diagnose 'A12.3' gestellt wurde `GET [base]/Encounter?_has:Condition:encounter:code=A12.3` Anwendungshinweis: Weitere Details siehe FHIR-Kernspezifikation, Abschnitt Reverse Chaining.
url	uri	MAY	Beispiel: `GET [base]/CodeSystem?url=http://example.org/fhir/CodeSystem/test` Anwendungshinweis: Weitere Details siehe FHIR-Kernspezifikation.

Anmerkungen zu Must-Support-Feldern

Feldname	Kurzbeschreibung	Hinweise
CodeSystem.url	Kanonische URL	Bedeutung: Eindeutige Url zur Identifizierung des CodeSystems. Absolute Url sind zu bevorzugen. Hinweise: OIDs SOLLTEN als weitere Identifier des CodeSystems verwendet werden. In jedem Fall SOLLTE eine Canonical Url vergeben werden.
CodeSystem.version	Version	Bedeutung: Version des CodeSystems Hinweise: Jede Änderung des CodeSystems MUSS eine Änderung in der Version des CodeSystems und gebundenen ValueSets nach sich ziehen. Die Versionierung SOLLTE auf dem Konzept von Semantic Versioning basieren.
CodeSystem.name	Name des Codesystems	Bedeutung: Maschinenlesbarer Name des CodeSystems Hinweise: Der Constraint cps-0 ist hierbei zu beachten.
CodeSystem.status	Status	Zeigt den aktuellen Status der Ressource an. WICHTIGER Hinweis für Implementierer: Alle server-seitigen Implementierungen MÜSSEN in der Lage sein, die systemintern möglichen Statuswerte korrekt in FHIR abzubilden, mindestens jedoch 'active' und 'retired''. Alle client-seitigen Implementierungen MÜSSEN in der Lage sein, sämtliche Status-Codes zu interpretieren und dem Anwender in angemessener Form darstellen zu können, beispielsweise durch Ausblenden/Durchstreichen von Ressourcen mit dem status `entered-in-error` und Ausgrauen von Ressourcen, die einen Plan- oder Entwurfs-Status haben.
CodeSystem.content	Vollständigkeit der Repräsentation	Bedeutung: Angabe, ob es sich um eine vollständige Repräsentation des CodeSystems oder nur um einen Auszug handelt. Hinweise: Alle in einem System möglichen Status-Werte müssen über FHIR korrekt repräsentiert werden können, mindestens jedoch die Status-Werte `fragment` und `complete`. Deren korrekte Abbildung wird im Rahmen des Bestätigungsverfahrens überprüft.
CodeSystem.concept		Bedeutung: Angabe der Konzepte, aus denen sich das CodeSystem zusammensetzt. Hinweise: Es MUSS mindestens ein Code und ein Anzeigetext spezifiziert werden.
CodeSystem.concept.code
CodeSystem.concept.display
CodeSystem.concept.definition
