Source Concept DetailsRelationshipTarget Concept DetailsComment
Codes from http://hl7.org/fhir/StructureDefinition/QuestionnaireResponse|1.0.2Codes from QuestionnaireResponse
QuestionnaireResponse.metametamaps to wider conceptQuestionnaireResponse.metaQuestionnaireResponse.metaElement `QuestionnaireResponse.meta` is mapped to FHIR R4B element `QuestionnaireResponse.meta` as `SourceIsBroaderThanTarget`. The mappings for `QuestionnaireResponse.meta` do not cover the following types: Meta. The mappings for `QuestionnaireResponse.meta` do not cover the following types based on type expansion: lastUpdated, profile, security, tag, versionId.
QuestionnaireResponse.implicitRulesimplicitRulesis equivalent toQuestionnaireResponse.implicitRulesQuestionnaireResponse.implicitRulesElement `QuestionnaireResponse.implicitRules` is mapped to FHIR R4B element `QuestionnaireResponse.implicitRules` as `Equivalent`. Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element as much as possible.
QuestionnaireResponse.languagelanguageis equivalent toQuestionnaireResponse.languageQuestionnaireResponse.languageElement `QuestionnaireResponse.language` is mapped to FHIR R4B element `QuestionnaireResponse.language` as `Equivalent`. Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).
QuestionnaireResponse.texttextmaps to wider conceptQuestionnaireResponse.textQuestionnaireResponse.textElement `QuestionnaireResponse.text` is mapped to FHIR R4B element `QuestionnaireResponse.text` as `SourceIsBroaderThanTarget`. The mappings for `QuestionnaireResponse.text` do not cover the following types: Narrative. The mappings for `QuestionnaireResponse.text` do not cover the following types based on type expansion: div, status. Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative.
QuestionnaireResponse.containedcontainedis equivalent toQuestionnaireResponse.containedQuestionnaireResponse.containedElement `QuestionnaireResponse.contained` is mapped to FHIR R4B element `QuestionnaireResponse.contained` as `SourceIsBroaderThanTarget`. This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again.
QuestionnaireResponse.identifieridentifiermaps to wider conceptQuestionnaireResponse.identifierQuestionnaireResponse.identifierElement `QuestionnaireResponse.identifier` is mapped to FHIR R4B element `QuestionnaireResponse.identifier` as `SourceIsBroaderThanTarget`. The mappings for `QuestionnaireResponse.identifier` do not cover the following types: Identifier. The mappings for `QuestionnaireResponse.identifier` do not cover the following types based on type expansion: assigner, period, system, type, use, value.
QuestionnaireResponse.questionnairequestionnairemaps to wider conceptQuestionnaireResponse.questionnaireQuestionnaireResponse.questionnaireElement `QuestionnaireResponse.questionnaire` is mapped to FHIR R4B element `QuestionnaireResponse.questionnaire` as `SourceIsBroaderThanTarget`. The mappings for `QuestionnaireResponse.questionnaire` do not cover the following types: Reference. The mappings for `QuestionnaireResponse.questionnaire` do not cover the following types based on type expansion: display, reference.
QuestionnaireResponse.statusstatusis equivalent toQuestionnaireResponse.statusQuestionnaireResponse.statusElement `QuestionnaireResponse.status` is mapped to FHIR R4B element `QuestionnaireResponse.status` as `SourceIsNarrowerThanTarget`. The mappings for `QuestionnaireResponse.status` do not allow expression of the necessary codes, per the bindings on the source and target.
QuestionnaireResponse.subjectsubjectmaps to wider conceptQuestionnaireResponse.subjectQuestionnaireResponse.subjectElement `QuestionnaireResponse.subject` is mapped to FHIR R4B element `QuestionnaireResponse.subject` as `SourceIsBroaderThanTarget`. The mappings for `QuestionnaireResponse.subject` do not cover the following types based on type expansion: display, reference. The standard extension `alternate-reference` has been mapped as the representation of FHIR DSTU2 element `QuestionnaireResponse.subject` with unmapped reference targets: Resource.
QuestionnaireResponse.authorauthormaps to wider conceptQuestionnaireResponse.authorQuestionnaireResponse.authorElement `QuestionnaireResponse.author` is mapped to FHIR R4B element `QuestionnaireResponse.author` as `RelatedTo`. The standard extension `alternate-reference` has been mapped as the representation of FHIR DSTU2 element `QuestionnaireResponse.author` with unmapped reference targets: Device, Patient, Practitioner, RelatedPerson. Mapping a subject's answers to multiple choice options and determining what to put in the textual answer is a matter of interpretation. Authoring by device would indicate that some portion of the questionnaire had been auto-populated.
QuestionnaireResponse.authoredauthoredis equivalent toQuestionnaireResponse.authoredQuestionnaireResponse.authoredElement `QuestionnaireResponse.authored` is mapped to FHIR R4B element `QuestionnaireResponse.authored` as `Equivalent`. May be different from the update time of the resource itself, because that is the status of the collection and authoring. This element is optional to allow for systems that may not know the value, however it SHOULD be populated if possible.
QuestionnaireResponse.sourcesourcemaps to wider conceptQuestionnaireResponse.sourceQuestionnaireResponse.sourceElement `QuestionnaireResponse.source` is mapped to FHIR R4B element `QuestionnaireResponse.source` as `RelatedTo`. The standard extension `alternate-reference` has been mapped as the representation of FHIR DSTU2 element `QuestionnaireResponse.source` with unmapped reference targets: Patient, Practitioner, RelatedPerson. If not specified, no inference can be made about who provided the data.
QuestionnaireResponse.encounterencountermaps to wider conceptQuestionnaireResponse.encounterQuestionnaireResponse.encounterElement `QuestionnaireResponse.encounter` is mapped to FHIR R4B element `QuestionnaireResponse.encounter` as `SourceIsBroaderThanTarget`. The mappings for `QuestionnaireResponse.encounter` do not cover the following types based on type expansion: display, reference. The standard extension `alternate-reference` has been mapped as the representation of FHIR DSTU2 element `QuestionnaireResponse.encounter` with unmapped reference targets: Encounter.
QuestionnaireResponse.groupgroupis related toQuestionnaireResponse.itemQuestionnaireResponse.itemElement `QuestionnaireResponse.group` is mapped to FHIR R4B element `QuestionnaireResponse.item` as `SourceIsNarrowerThanTarget`. The Questionnaire itself has one "root" group with the actual contents of the Questionnaire.

The mappings for `QuestionnaireResponse.group.question.answer.value[x]` do not cover the following types: Attachment, instant. The target context `QuestionnaireResponse.item.answer.value[x]` is a choice-type element and cannot directly hold extensions. The context is moved up to parent element `QuestionnaireResponse.item.answer`. The standard extension `alternate-reference` has been mapped as PART of the representation of FHIR DSTU2 element `QuestionnaireResponse.group.question.answer.value[x]` with unmapped reference targets: Resource. Source element `QuestionnaireResponse.group.question.answer.value[x]` has unmapped reference types. While the target element `QuestionnaireResponse.item.answer.value[x]` is a choice type and does not allow extensions, the `alternate-reference` extension can be applied to Reference values within it. More complex structures (Attachment, Resource and Quantity) will typically be limited to electronic forms that can expose an appropriate user interface to capture the components and enforce the constraints of a complex data type. Additional complex types can be introduced through extensions.
