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 element Element IdShort description An identifier intended for computation Definition An identifier - identifies some entity uniquely and unambiguously. Typically this is used for business identifiers.
Identifier Constraints- ele-1:All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count())
- 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

| use | Σ ?! | 0..1 | codeBinding | There are no (further) constraints on this element Element IdShort description usual | official | temp | secondary | old (If known) Definition The purpose of this identifier.
Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.
Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.
code Binding Identifies the purpose for this identifier, if known . IdentifierUse (required)Constraints- ele-1:All FHIR elements must have a @value or children

| type | Σ | 1..1 | CodeableConceptBinding | Element IdShort description Description of identifier Definition A coded type for the identifier that can be used to determine which identifier to use for a specific purpose.
Allows users to make use of identifiers when the identifier system is not known.
This element deals only with general categories of identifiers. 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.

| system | Σ | 1..1 | uri | There are no (further) constraints on this element Element IdShort description The namespace for the identifier value Definition Establishes the namespace for the value - that is, a URL that describes a set values that are unique.
There 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.
Identifier.system is always case sensitive.

| value | Σ | 1..1 | string | There are no (further) constraints on this element Element IdShort description The value that is unique Definition The portion of the identifier typically relevant to the user and which is unique within the context of the system.
If 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.

| period | Σ I | 0..1 | Period | There are no (further) constraints on this element Element IdShort description Time period when id is/was valid for use Definition Time period during which identifier is/was valid for use.
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.

The Identifier.assigner may omit the .reference element and only contain a .display element reflecting the name or other textual information about the assigning organization.

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 Terminologie - Namensräume - Lokale Namensräume.
