Definitions for the ehealth-questionnaireresponse resource profile.
1. QuestionnaireResponse | |
Definition | A structured set of questions and their answers. The questions are ordered and grouped into coherent subsets, corresponding to the structure of the grouping of the questionnaire being responded to. |
Control | 0..* |
Alternate Names | Form, QuestionnaireAnswers |
Comments | The QuestionnaireResponse contains enough information about the questions asked and their organization that it can be interpreted somewhat independently from the Questionnaire it is based on. I.e. You don't need access to the Questionnaire in order to extract basic information from a QuestionnaireResponse. |
Invariants | Defined on this element dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources (: contained.contained.empty()) dom-3: If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource (: contained.where((('#'+id in (%resource.descendants().reference | %resource.descendants().as(canonical) | %resource.descendants().as(uri) | %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(canonical) = '#').exists()).not()).trace('unmatched', id).empty()) dom-4: If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated (: contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()) dom-5: If a resource is contained in another resource, it SHALL NOT have a security label (: contained.meta.security.empty()) dom-6: A resource should have narrative for robust management (: text.`div`.exists()) |
2. QuestionnaireResponse.id | |
Definition | The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes. |
Control | 0..1 |
Type | string |
Comments | The only time that a resource does not have an id is when it is being submitted to the server using a create operation. |
3. QuestionnaireResponse.meta | |
Definition | The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource. |
Control | 0..1 |
Type | Meta |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
4. QuestionnaireResponse.implicitRules | |
Definition | A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc. |
Control | 0..1 |
Type | uri |
Is Modifier | true |
Comments | 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. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc. |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
5. QuestionnaireResponse.language | |
Definition | The base language in which the resource is written. |
Control | 0..1 |
Binding | The codes SHOULD be taken from CommonLanguages Max Binding: AllLanguages A human language. |
Type | code |
Comments | 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). |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
6. QuestionnaireResponse.text | |
Definition | A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety. |
Control | 0..1 |
Type | Narrative |
Alternate Names | narrative, html, xhtml, display |
Comments | Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later. |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
7. QuestionnaireResponse.contained | |
Definition | These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope. |
Control | 0..* |
Type | Resource |
Alternate Names | inline resources, anonymous resources, contained resources |
Comments | 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. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels. |
8. QuestionnaireResponse.extension | |
Definition | An Extension |
Control | 2..* |
Type | Extension |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
Slicing | This element introduces a set of slices on QuestionnaireResponse.extension. The slices are unordered and Open, and can be differentiated using the following discriminators:
|

10. QuestionnaireResponse.extension:quality | |
SliceName | quality |
Definition | Minimum required or actually assessed quality values. The qualityType element states the type of quality. For different values of qualityType the required or assessed quality value (qualityCode) must be from different value sets. The relation between qualityType and allowed value sets are defined in the definition of value set http://ehealth.sundhed.dk/vs/quality-types. |
Control | 0..* This element is affected by the following invariants: ele-1 |
Type | Extension(ehealth-quality) (Extension Type: Choice of: base64Binary, boolean, canonical, code, date, dateTime, decimal, id, instant, integer, markdown, oid, positiveInt, string, time, unsignedInt, uri, url, uuid, Address, Age, Annotation, Attachment, CodeableConcept, Coding, ContactPoint, Count, Distance, Duration, HumanName, Identifier, Money, Period, Quantity, Range, Ratio, Reference, SampledData, Signature, Timing, ContactDetail, Contributor, DataRequirement, Expression, ParameterDefinition, RelatedArtifact, TriggerDefinition, UsageContext, Dosage, Meta) |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
11. QuestionnaireResponse.extension:resolvedTiming | |
SliceName | resolvedTiming |
Definition | Resolved timing reflects whether a measurement (Observation, QuestionnaireResponse or Media) has been performed ad-hoc or as fulfillment of a measurement regime time slot in which case the extent of the time slot is given by start and end. If the measurement regime has a form for which a time slot cannot be resolved or determining is/was not supported, the type unresolved is used. |
Control | 1..1 This element is affected by the following invariants: ele-1 |
Type | Extension(ehealth-resolved-timing) (Extension Type: Choice of: base64Binary, boolean, canonical, code, date, dateTime, decimal, id, instant, integer, markdown, oid, positiveInt, string, time, unsignedInt, uri, url, uuid, Address, Age, Annotation, Attachment, CodeableConcept, Coding, ContactPoint, Count, Distance, Duration, HumanName, Identifier, Money, Period, Quantity, Range, Ratio, Reference, SampledData, Signature, Timing, ContactDetail, Contributor, DataRequirement, Expression, ParameterDefinition, RelatedArtifact, TriggerDefinition, UsageContext, Dosage, Meta) |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
12. QuestionnaireResponse.modifierExtension | |
Definition | May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. 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 is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself). |
Control | 0..* |
Type | Extension |
Is Modifier | true |
Requirements | Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions. |
Alternate Names | extensions, user content |
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. |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |

Note | This is a business identifier, not a resource identifier (see discussion) |
Control | 0..1 |
Type | Identifier |
Requirements | Used for tracking, registration and other business purposes. |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |

Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
16. QuestionnaireResponse.questionnaire | |
Definition | The Questionnaire that defines and organizes the questions for which answers are being provided. |
Control | 1..1 |
Type | canonical(ehealth-questionnaire : {r) |
Requirements | Needed to allow editing of the questionnaire response in a manner that enforces the constraints of the original form. |
Alternate Names | Form |
Comments | If a QuestionnaireResponse references a Questionnaire, then the QuestionnaireResponse structure must be consistent with the Questionnaire (i.e. questions must be organized into the same groups, nested questions must still be nested, etc.). |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
17. QuestionnaireResponse.status | |
Definition | The position of the questionnaire response within its overall lifecycle. |
Control | 1..1 |
Binding | The codes SHALL be taken from QuestionnaireResponseStatus Lifecycle status of the questionnaire response. |
Type | code |
Is Modifier | true |
Requirements | The information on Questionnaire resources may possibly be gathered during multiple sessions and altered after considered being finished. |
Comments | This element is labeled as a modifier because the status contains codes that mark the resource as not currently valid. |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
18. QuestionnaireResponse.subject | |
Definition | The subject of the questionnaire response. This could be a patient, organization, practitioner, device, etc. This is who/what the answers apply to, but is not necessarily the source of information. |
Control | 1..1 |
Type | Reference(Resource) |
Requirements | Allows linking the answers to the individual the answers describe. May also affect access control. |
Alternate Names | Patient, Focus |
Comments | If the Questionnaire declared a subjectType, the resource pointed to by this element must be an instance of one of the listed types. |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
19. QuestionnaireResponse.encounter | |
Definition | The Encounter during which this questionnaire response was created or to which the creation of this record is tightly associated. |
Control | 0..1 |
Type | Reference(Encounter) |
Requirements | Provides context for the information that was captured. May also affect access control. |
Comments | This will typically be the encounter the event occurred within, but some activities may be initiated prior to or after the official completion of an encounter but still be tied to the context of the encounter. A questionnaire that was initiated during an encounter but not fully completed during the encounter would still generally be associated with the encounter. |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
20. QuestionnaireResponse.authored | |
Definition | The date and/or time that this set of answers were last changed. |
Control | 1..1 |
Type | dateTime |
Requirements | Clinicians need to be able to check the date that the information in the questionnaire was collected, to derive the context of the answers. |
Alternate Names | Date Created, Date published, Date Issued, Date updated |
Comments | May be different from the lastUpdateTime of the resource itself, because that reflects when the data was known to the server, not when the data was captured. This element is optional to allow for systems that might not know the value, however it SHOULD be populated if possible. |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
21. QuestionnaireResponse.author | |
Definition | Person who received the answers to the questions in the QuestionnaireResponse and recorded them in the system. |
Control | 0..1 |
Type | Reference(ehealth-device | ehealth-practitioner | ehealth-patient | ehealth-relatedperson : {r) |
Requirements | Need to know who interpreted the subject's answers to the questions in the questionnaire, and selected the appropriate options for answers. |
Alternate Names | Laboratory, Service, Practitioner, Department, Company, Performer |
Comments | 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. |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
22. QuestionnaireResponse.source | |

Comments | If not specified, no inference can be made about who provided the data. |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
23. QuestionnaireResponse.item | |
Definition | A group or question item from the original questionnaire for which answers are provided. |
Control | 0..* |
Type | BackboneElement |
Comments | Groups cannot have answers and therefore must nest directly within item. When dealing with questions, nesting must occur within each answer because some questions may have multiple answers (and the nesting occurs for each answer). |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) qrs-1: Nested item can't be beneath both item and answer (: (answer.exists() and item.exists()).not()) |
24. QuestionnaireResponse.item.id | |
Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
Control | 0..1 |
Type | string |
25. QuestionnaireResponse.item.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. |

27. QuestionnaireResponse.item.linkId | |
Definition | The item from the Questionnaire that corresponds to this item in the QuestionnaireResponse resource. |
Control | 1..1 |
Type | string |
Requirements | Items can repeat in the answers, so a direct 1..1 correspondence by position might not exist - requiring correspondence by identifier. |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
28. QuestionnaireResponse.item.definition | |
Definition | A reference to an ElementDefinition that provides the details for the item. |
Control | 0..1 |
Type | uri |
Requirements | A common pattern is to define a set of data elements, and then build multiple different questionnaires for different circumstances to gather the data. This element provides traceability to the common definition. |
Comments | The ElementDefinition must be in a StructureDefinition, and must have a fragment identifier that identifies the specific data element by its id (Element.id). E.g. http://hl7.org/fhir/StructureDefinition/Observation#Observation.value[x]. There is no need for this element if the item pointed to by the linkId has a definition listed. |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) |
