R5: Person.communication (new:BackboneElement)


Optional Extension Element - found in all resources.

ShortR5: A language which may be used to communicate with the person about his or her health (new)Optional Extensions Element
Comments

Element Person.communication has a context of Person based on following the parent source element upwards and mapping to Person. Element Person.communication has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element). If no language is specified, this implies that the default local language is spoken. If you need to convey proficiency for multiple modes, then you need multiple Person.Communication associations. For animals, language is not a relevant field, and should be absent from the instance. If the Patient does not speak the default local language, then the Interpreter Required Standard can be used to explicitly declare that an interpreter is required.

Note that this property should not be used to update any linked/logically linked practitioner resources as it serves as a language that can be used to communicate with patients - however it may be used to inform the value on practitioner, along with their role at the organization (with the practitioner's permission)

Definition

An Extension


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.

    Element Person.communication.language is part of an existing definition because parent element Person.communication requires a cross-version extension. Element Person.communication.language has a context of Person based on following the parent source element upwards and mapping to Person. Element Person.communication.language has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element). The structure aa-BB with this exact casing is one the most widely used notations for locale. However not all systems actually code this but instead have it as free text. Hence CodeableConcept instead of code as the data type.

          20. Extension.extension:preferred.extension
          Definition

          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 definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension.
