R5: Observation.value[x] additional types (Attachment, Reference(http://hl7.org/fhir/StructureDefinition/MolecularSequence))


Optional Extension Element - found in all resources.

Comments

Element Observation.value[x] is mapped to FHIR R4 element Observation.value[x] as SourceIsBroaderThanTarget. The mappings for Observation.value[x] do not cover the following types: Attachment, Reference. The target context Observation.value[x] is a choice-type element and cannot directly hold extensions. The context is moved up to parent element Observation.

  • An observation may have:
    1. a single value here
    2. both a value and a set of related or component values
    3. only a set of related or component values.
  • If a value is present, the datatype for this element should be determined by the code.
  • CodeableConcept with just a text would be used instead of a string if the field was usually coded, or if the type associated with the code defines a coded value.
  • Attachment is used if the observation result value is a binary file such as an image. If the observation result value is derived from the binary file (for example 'X' detected and here is the the proof in this image), the binary file may be directly represented using DocumentReference and referenced by derivedFrom.
  • The usage of valueReference is restricted to the MolecularSequence resource when used as a definitional resource, not as a patient-specific finding. .
  • For additional guidance, see the Notes section below.

4. Extension.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.

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.
