| Official URL: http://ehealth.sundhed.dk/fhir/StructureDefinition/ehealth-definedquestion | Version: 11.0.1 | |||
| Active as of 2026-10-23 | Computable Name: ehealth-definedquestion | |||
The ehealth-definedquestion profile of StructureDefinition represents the concept of a DefinedQuestion. A DefinedQuestion is a standalone representation of a question and possibly its answer options that can be used in one or more Questionnaire resources. Although a Questionnaire can be constructed without being based on any DefinedQuestion, it is expected that a catalogue of DefinedQuestion will emerge over time and the particular DefinedQuestion will be reused in multiple Questionnaire.
The DefinedQuestion concept is based on ideas described in https://www.hl7.org/fhir/stu3/questionnaire.html#2.38.5.4. Whether a DefinedQuestion is referenced in a Questionnaire or not, it is the Questionnaire's own definition which takes precedence.
In the eHealth Infrastructure, a reference to a DefinedQuestion by url in a Questionnaire question is used to enable robust extraction in automated processing rule(s) of answer(s) to that question from corresponding QuestionnaireResponse. An answer in a QuestionnaireResponse is already unambiguously related to a question in a Questionnaire through the question's linkId. If the same question is used in another Questionnaire it will likely end up with a different linkId in that Questionnaire. By referencing a DefinedQuestion by its url in Questionnaire.item.definition, the same question can be referenced unambiguously in multiple Questionnaire.
Multiple DefinedQuestion with identical url can coexist as long as they have differing business versions in version. This way, different versions of the same question can have different answer options.
When using a DefinedQuestion in a Questionnaire, the Questionnaire.item.definition element must contain the url followed by a pipe and the business version thereby referencing a versioned DefinedQuestion.
An automated processing rule captured in a Library resource can, when extracting answer(s) to the question in a QuestionnaireResponse, choose to search for either the versioned reference or the version-less reference to a DefinedQuestion. The latter can be obtained by disregarding the pipe and business version in the rule logic.
The actual details of the DefinedQuestion's question and possible answers are described in the ElementDefinition found in either snapshot.element or differential.element.
