Organisationsinterner Patienten-Identifier (PID)
Name: IdentifierPid (Simplifier Projekt Link)
Canonical: http://fhir.de/StructureDefinition/identifier-pid
| Identifier |  |  | Identifier | There are no (further) constraints on this elementElement IdShort description An identifier intended for computationDefinition Data TypeAn identifier - identifies some entity uniquely and unambiguously. Typically this is used for business identifiers.IdentifierConstraints Mappingsele-1:All FHIR elements must have a @value or children
 hasValue() or (children().count() > id.count())
rim:n/av2: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

It SHOULD not be used for codes that correspond 1..1 with the Identifier.system. Some identifiers may fall into multiple categories due to common usage.   Where the system is known, a type is unnecessary because the type is always part of the system definition. However systems often need to handle identifiers where the system is not known. There is not a 1:1 relationship between type and system, since many different systems have the same type.CodeableConceptBinding A coded type for an identifier that can be used to determine which identifier to use for a specific purpose.Identifier Type Codes (extensible)Constraints Patternele-1:All FHIR elements must have a @value or children

| system | Σ | 1..1 | uri | There are no (further) constraints on this elementElement IdShort description The namespace for the identifier valueDefinition RequirementsEstablishes the namespace for the value - that is, a URL that describes a set values that are unique.CommentsThere are many sets  of identifiers.  To perform matching of two identifiers, we need to know what set we're dealing with. The system identifies a particular set of unique identifiers.Data TypeIdentifier.system is always case sensitive.uriConstraints Examplesele-1:All FHIR elements must have a @value or children

| value | Σ | 1..1 | string | There are no (further) constraints on this elementElement IdShort description The value that is uniqueDefinition CommentsThe portion of the identifier typically relevant to the user and which is unique within the context of the system.Data TypeIf the value is a full URI, then the system SHALL be urn:ietf:rfc:3986.  The value's primary purpose is computational mapping.  As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.)  A value formatted for human display can be conveyed using the Rendered Value extension. Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe.stringConstraints Examplesele-1:All FHIR elements must have a @value or children

Period is not used for a duration (a measure of elapsed time). See Duration.PeriodConstraints Mappingsele-1:All FHIR elements must have a @value or children

Kontext: Der Identifier kann u.a. in Patient.identifier verwendet werden
Da es beim organisationsinternen Identifier keinen einheitlichen Namensraum gibt, ist hier die Angabe des type-Codes "MR" (Medical Record Number) verpflichtend, um die PID einrichtungsübergreifend als solche erkennen zu können.
Jede Einrichtung muss für ihren Namensraum eine NamingSystem-URL festlegen.
Hinweise zur Nomenklatur organisationsinterner Identifier.system-URLs siehe Lokale Namensräume.
