/ClinicalDocument/component/structuredBody/component/section/entry/organizer/component/observation

An item inside a subgroup

• Root item with type: “Group” (QRD section)

  • Sub group item with type: “Group” (QRD organizer)

    • Question item

Multiple Choice Response if

• item.type is choice

• item.extension has no extension containing http://hl7.org/fhir/StructureDefinition/questionnaire-itemControl with value ‘slider’

Id

…/observation/id

Uses Id from QFFD question

Validating if Questionnaire item(item.extension.externalIdentifier) matches QFDD question id

Code

…/observation/code

Uses code from Questionnaire item item.code

Code: item.code.code

CodeSystem: ifitem.code.system has prefix “urn:oid:” then item.code.system without prefix. Else lookup in Questionnaire Terminology.

CodeSystemName: is fetched from CodeSystem in Questionnaire Terminology. Value is taken in the following order: codeSystem.title, codeSystem.name, codeSystem.url or “Unknown“.

Display: item.text or else item.code.display

OriginalText: Question text (item.text) or, if not present, (item.code.display)

Answer

…/observation/value

Value: from QuestionnaireResponse.item.answer .

For Questionnaire.item.type = choice , the question answer(s) is one or more coded elements in QRD. Question answer code is from QuestionnaireResponse.item.answer.valueCoding.

Code: answer.code

CodeSystem: if answer.system has prefix “urn:oid:” then item.code.system without prefix. Else lookup in Questionnaire Terminology.

CodeSystemName: is fetched from CodeSystem in Questionnaire Terminology. Value is taken in the following order: codeSystem.title, codeSystem.name, codeSystem.url or “Unknown“.

Display: answer.display

Associated text question

…/observation/entryRelationship

Is added if Questionnaire item has one or more extensions:

• http://ehealth.sundhed.dk/fhir/StructureDefinition/ehealth-questionnaire-helpText

• http://ehealth.sundhed.dk/fhir/StructureDefinition/ehealth-questionnaire-image

And if QFDD has associated text question and preconditions are fulfilled.

Structure for associated text question in FHIR Questionnaire:

• Root item with type: “Group” (QRD section)

  • Sub group item with type: “Group” (QRD organizer)

    • Question item with type: “choice“

    • Associated text question item (The item must be right after the question)

OBS: Supported precondition for Associated text question:

• Only one precondition element

• The precondition is only based on answers from the related multiple choice (no reference to other questions)

• Supported groupers inside the one preconditon element

  • AllTrue

  • AllFalse

  • AtLeastOneTrue

  • AtLeaseOneFalse

  • OnlyOneTrue

  • OnlyOneFalse

External reference

…/observation/reference

The QFDD unique id. From id element and the property 'extension'

Range

…/observation/referenceRange

If Questionnaire.item has the following extension the referenceRange is assigned

• http://hl7.org/fhir/StructureDefinition/minValue

• http://hl7.org/fhir/StructureDefinition/maxValue
