## Resource Profile: EEHealthDeclarationQuestionnaire - Detailed Descriptions

Draft as of 2024-01-01

Definitions for the ee-health-declaration-questionnaire resource profile.

- Key Elements Table
- Differential Elements Table
- Snapshot Elements Table

Guidance on how to interpret the contents of this table can be foundhere

0. Questionnaire
Definition | A structured set of questions intended to guide the collection of answers from end-users. Questionnaires provide detailed control over order, presentation, phraseology and grouping to allow coherent, consistent data collection.
Short | A structured set of questions
Control | 0..*
Is Modifier | false
Must Support | false
Summary | false
Alternate Names | Form, CRF, Survey
Invariants | cnl-0: Name should be usable as an identifier for the module by machine processing applications such as code generation (name.exists() implies name.matches('^[A-Z]([A-Za-z0-9_]){1,254}$')) que-2: The link ids for groups and questions must be unique within the questionnaire (descendants().linkId.isDistinct())
2. Questionnaire.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.
Short | A set of rules under which this content was created
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 its narrative along with other profiles, value sets, etc.
Control | 0..1
Type | uri
Is Modifier | true because This element is labeled as a modifier because the implicit rules may provide additional knowledge about the resource that modifies its meaning or interpretation
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Must Support | false
Summary | true
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
4. Questionnaire.contained
Definition | These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, nor can they have their own independent transaction scope. This is allowed to be a Parameters resource if and only if it is referenced by a resource that provides context/meaning.
Short | Contained, inline 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.
Control | 0..0* This element is affected by the following invariants: dom-2, dom-4, dom-3, dom-5
Type | Resource
Is Modifier | false
Must Support | false
Summary | false
Alternate Names | inline resources, anonymous resources, contained resources
6. Questionnaire.extension
Definition | An Extension May be used to represent additional information that is not part of the basic definition of the resource. To make the use of extensions safe and managable, 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.
Short | ExtensionAdditional content defined by implementations
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.
Control | 0..0*
Type | Extension
Is Modifier | false
Must Support | false
Summary | false
Alternate Names | extensions, user content
Invariants | 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())
8. Questionnaire.modifierExtension
Definition | An Extension 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 managable, 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).
Short | ExtensionExtensions that cannot be ignored
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.
Control | 0..0*
Type | Extension
Is Modifier | true because Modifier extensions are expected to modify the meaning or interpretation of the resource that contains them
Must Support | false
Summary | 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
Invariants | 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())
10. Questionnaire.url
Definition | An absolute URI that is used to identify this questionnaire when it is referenced in a specification, model, design or an instance; also called its canonical identifier. This SHOULD be globally unique and SHOULD be a literal address at which an authoritative instance of this questionnaire is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the questionnaire is stored on different servers.
Short | Canonical identifier for this questionnaire, represented as an absolute URI (globally unique)
Comments | Can be a urn:uuid: or a urn:oid: but real http: addresses are preferred. Multiple instances may share the same URL if they have a distinct version. The determination of when to create a new version of a resource (same url, new version) vs. defining a new artifact is up to the author. Considerations for making this decision are found in Technical and Business Versions. In some cases, the resource can no longer be found at the stated url, but the url itself cannot change. Implementations can use the meta.source element to indicate where the current master source of the resource can be found. The name of the referenced questionnaire can be conveyed using the http://hl7.org/fhir/StructureDefinition/display extension.
Control | 10..1
Type | uri
Is Modifier | false
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Must Support | false
Summary | true
Requirements | Allows the questionnaire to be referenced by a single globally unique identifier. This is the id that will be used to link a QuestionnaireResponse to the Questionnaire the response is for.
Invariants | cnl-1: URL should not contain | or # - these characters make processing canonical references problematic (exists() implies matches('^[^|# ]+$')) ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
12. Questionnaire.identifier
Definition | A formal identifier that is used to identify this questionnaire when it is represented in other formats, or referenced in a specification, model, design or an instance.
Short | Business identifier for questionnaire
Comments | Typically, this is used for identifiers that can go in an HL7 V3 II (instance identifier) data type, and can then identify this questionnaire outside of FHIR, where it is not possible to use the logical URI.
Note | This is a business identifier, not a resource identifier (see discussion)
Control | 0..0*
Type | Identifier
Is Modifier | false
Must Support | false
Summary | true
Requirements | Allows externally provided and/or usable business identifiers to be easily associated with the questionnaire.
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
14. Questionnaire.version
Definition | The identifier that is used to identify this version of the questionnaire when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the questionnaire author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence.
Short | Business version of the questionnaire
Comments | There may be different questionnaires that have the same url but different versions. The version can be appended to the url in a reference to allow a reference to a particular business version of the questionnaire with the format. The version SHOULD NOT contain a '#' - see Business Version.
Note | This is a business version Id, not a resource version Id (see discussion)
Control | 10..1
Type | string
Is Modifier | false
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Must Support | false
Summary | true
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
16. Questionnaire.versionAlgorithm[x]
Definition | Indicates the mechanism used to compare versions to determine which is more current.
Short | How to compare versions
Comments | If set as a string, this is a FHIRPath expression that has two additional context variables passed in - %version1 and %version2 and will return a negative number if version1 is newer, a positive number if version2 and a 0 if the version ordering can't be successfully be determined.

This element is a URI that refers to an ElementDefinition or to an ObservationDefinition that provides information about this item, including information that might otherwise be included in the instance of the Questionnaire resource. A detailed description of the construction of the URI is shown in Comments, below.
Short | ElementDefinition - details for the item
Comments | The uri refers to an ElementDefinition in a StructureDefinition or to an ObservationDefinition and always starts with the canonical URL for the target resource. When referring to a StructureDefinition, a fragment identifier is used to specify the element definition by its id Element.id. E.g. http://hl7.org/fhir/StructureDefinition/Observation#Observation.value[x]. In the absence of a fragment identifier, the first/root element definition in the target is the matching element definition. The uri refers to an ElementDefinition in a StructureDefinition or to an ObservationDefinition and always starts with the canonical URL for the target resource.

Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Must Support | false
Summary | false
Requirements | A common pattern is to define a set of data elements and then build multiple questionnaires for different circumstances to gather the data. This element provides traceability to the common definition and allows the content for the question to come from the underlying definition.
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
54. Questionnaire.item.type
Definition | The type of questionnaire item this is - whether text for display, a grouping of other items or a particular type of data to be captured (string, integer, Coding, etc.).
Short | group | display | boolean | decimal | integer | date | dateTime +

56. Questionnaire.item.enableWhen
Definition | A constraint indicating that this item should only be enabled (displayed/allow answers to be captured) when the specified condition is true.
Short | Only allow data when
Comments | If multiple repetitions of this extension are present, the interpretation is driven by enableBehavior (either all repetitions must evaluate to true for this item to be enabled, or only one must evaluate to true for the item to be enabled). If the enableWhen.question has multiple answers, the condition evaluates to true if any of the answers for the referenced item match the enableWhen condition. This element is a modifier because if enableWhen is present for an item, "required" is ignored unless one of the enableWhen conditions is met. When an item is disabled, all of its descendants are disabled, regardless of what their own enableWhen logic might evaluate to. If enableWhen logic depends on an item that is disabled, the logic should proceed as though the item is not valued - even if a default value or other value might be retained in memory in the event of the item being re-enabled. In some cases, the comparison between the indicated answer and the specified value may differ only by precision. For example, the enableWhen might be Q1 > 1970, but the answer to Q1 is 1970-10-15. There is not a clear answer as to whether 1970-10-15 should be considered 'greater' than 1970, given that it is an imprecise value. In these indeterminate situations, the form filler has the option of refusing to render the form. If the form is displayed, items where enableWhen is indeterminate SHOULD be treated as enabled with a warning indicating that the questionnaire logic was faulty and it is possible that the item should not be enabled. Questionnaires SHOULD be designed to take into account challenges around varying precision to minimize non-deterministic situations by setting constraints around expected precision, etc.

62. Questionnaire.item.enableWhen.modifierExtension
Definition | An Extension May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained 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 managable, 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.

64. Questionnaire.item.enableWhen.question
Definition | The linkId for the question whose answer (or lack of answer) governs whether this item is enabled.
Short | The linkId of question that determines whether item is enabled/disabled
Comments | If multiple question occurrences are present for the same question (same linkId), then this refers to the nearest question occurrence reachable by tracing first the "ancestor" axis and then the "preceding" axis and then the "following" axis. If there are multiple items with the same linkId and all are equadistant (e.g. a question references a question that appears in a separate repeating group), that is an error. (Consider using the enableWhenExpression extension to define logic to handle such a situation.)

70. Questionnaire.item.required
Definition | An indication, if true, that the item must be present in a "completed" QuestionnaireResponse. If false, the item may be skipped when answering the questionnaire.
Short | Whether the item must be included in data results
Comments | If the required item is a question, it must have a direct answer (i.e. an answer to the question itself, not merely answers to child questions) in order for the QuestionnaireResponse to be complete. If the required item is a group, it must have at least one descendant question which has an answer Questionnaire.item.required only has meaning for elements that are conditionally enabled with enableWhen if the condition evaluates to true. It also only has meaning if the parent element is present. If a non-required 'group' item contains a 'required' question item, it's completely fine to omit the group (because it's not required) despite it having a required child. Similarly, if an item that contains other items is marked as required, that does not automatically make the contained elements required (though required groups must contain at least one descendant item with a populated answer). The value for 'required' may come from the ElementDefinition referred to by .definition.

72. Questionnaire.item.repeats
Definition | An indication, if true, that a QuestionnaireResponse for this item may include multiple answers associated with a single instance of this item (for question-type items) or multiple repetitions of the item (for group-type items).
Short | Whether the item may repeat
Comments | If a question is marked as repeats=true, then multiple answers can be provided for the question in the corresponding QuestionnaireResponse. When rendering the questionnaire, it is up to the rendering software whether to render the question text for each answer repetition (i.e. "repeat the question") or to simply allow entry/selection of multiple answers for the question (repeat the answers). Which is most appropriate visually may depend on the type of answer as well as whether there are nested items. The resulting QuestionnaireResponse will be populated the same way regardless of rendering - one 'question' item with multiple answer values. The value may come from the ElementDefinition referred to by .definition. When repeats=true for a group, it'll be represented with multiple items with the same linkId in the QuestionnaireResponse. For a question, it'll be represented by a single item with that linkId with multiple answers.

2. Questionnaire.id
Definition | The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.

6. Questionnaire.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.
Short | A set of rules under which this content was created
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 its narrative along with other profiles, value sets, etc.

Definition | The base language in which the resource is written.
Short | Language of the resource content
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).

10. Questionnaire.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.
Short | Text summary of the resource, for human interpretation
Comments | Contained resources do not have a 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.

Definition | These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, nor can they have their own independent transaction scope. This is allowed to be a Parameters resource if and only if it is referenced by a resource that provides context/meaning.
Short | Contained, inline 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.

18. Questionnaire.url
Definition | An absolute URI that is used to identify this questionnaire when it is referenced in a specification, model, design or an instance; also called its canonical identifier. This SHOULD be globally unique and SHOULD be a literal address at which an authoritative instance of this questionnaire is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the questionnaire is stored on different servers.
Short | Canonical identifier for this questionnaire, represented as an absolute URI (globally unique)
Comments | Can be a urn:uuid: or a urn:oid: but real http: addresses are preferred. Multiple instances may share the same URL if they have a distinct version. The determination of when to create a new version of a resource (same url, new version) vs. defining a new artifact is up to the author. Considerations for making this decision are found in Technical and Business Versions. In some cases, the resource can no longer be found at the stated url, but the url itself cannot change. Implementations can use the meta.source element to indicate where the current master source of the resource can be found. The name of the referenced questionnaire can be conveyed using the http://hl7.org/fhir/StructureDefinition/display extension.

20. Questionnaire.identifier
Definition | A formal identifier that is used to identify this questionnaire when it is represented in other formats, or referenced in a specification, model, design or an instance.
Short | Business identifier for questionnaire
Comments | Typically, this is used for identifiers that can go in an HL7 V3 II (instance identifier) data type, and can then identify this questionnaire outside of FHIR, where it is not possible to use the logical URI.
Note | This is a business identifier, not a resource identifier (see discussion)

78. Questionnaire.code.version
Definition | The version of the code system which was used when choosing this code. Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged.

96. Questionnaire.item.definition
Definition | This element is a URI that refers to an ElementDefinition or to an ObservationDefinition that provides information about this item, including information that might otherwise be included in the instance of the Questionnaire resource. A detailed description of the construction of the URI is shown in Comments, below.
Short | ElementDefinition - details for the item
Comments | The uri refers to an ElementDefinition in a StructureDefinition or to an ObservationDefinition and always starts with the canonical URL for the target resource. When referring to a StructureDefinition, a fragment identifier is used to specify the element definition by its id Element.id. E.g. http://hl7.org/fhir/StructureDefinition/Observation#Observation.value[x]. In the absence of a fragment identifier, the first/root element definition in the target is the matching element definition.

100. Questionnaire.item.prefix
Definition | A short label for a particular group, question or set of display text within the questionnaire used for reference by the individual completing the questionnaire.
Short | E.g. "1(a)", "2.5.3"
Comments | These are generally unique within a questionnaire, though this is not guaranteed. Some questionnaires may have multiple questions with the same label with logic to control which gets exposed. Typically, these won't be used for "display" items, though such use is not prohibited. Systems SHOULD NOT generate their own prefixes if prefixes are defined for any items within a Questionnaire.

Invariants | ele-1: All FHIR elements must have a @value or children (`hasValue() or (children().count() > id.count())`)
106. Questionnaire.item.enableWhen
Definition | A constraint indicating that this item should only be enabled (displayed/allow answers to be captured) when the specified condition is true.
Short | Only allow data when
Comments | If multiple repetitions of this extension are present, the interpretation is driven by enableBehavior (either all repetitions must evaluate to true for this item to be enabled, or only one must evaluate to true for the item to be enabled). If the enableWhen.question has multiple answers, the condition evaluates to true if any of the answers for the referenced item match the enableWhen condition. This element is a modifier because if enableWhen is present for an item, "required" is ignored unless one of the enableWhen conditions is met. When an item is disabled, all of its descendants are disabled, regardless of what their own enableWhen logic might evaluate to. If enableWhen logic depends on an item that is disabled, the logic should proceed as though the item is not valued - even if a default value or other value might be retained in memory in the event of the item being re-enabled. In some cases, the comparison between the indicated answer and the specified value may differ only by precision. For example, the enableWhen might be Q1 > 1970, but the answer to Q1 is 1970-10-15. There is not a clear answer as to whether 1970-10-15 should be considered 'greater' than 1970, given that it is an imprecise value. In these indeterminate situations, the form filler has the option of refusing to render the form. If the form is displayed, items where enableWhen is indeterminate SHOULD be treated as enabled with a warning indicating that the questionnaire logic was faulty and it is possible that the item should not be enabled. Questionnaires SHOULD be designed to take into account challenges around varying precision to minimize non-deterministic situations by setting constraints around expected precision, etc.

114. Questionnaire.item.enableWhen.question
Definition | The linkId for the question whose answer (or lack of answer) governs whether this item is enabled.
Short | The linkId of question that determines whether item is enabled/disabled
Comments | If multiple question occurrences are present for the same question (same linkId), then this refers to the nearest question occurrence reachable by tracing first the "ancestor" axis and then the "preceding" axis and then the "following" axis. If there are multiple items with the same linkId and all are equadistant (e.g. a question references a question that appears in a separate repeating group), that is an error. (Consider using the enableWhenExpression extension to define logic to handle such a situation.)

124. Questionnaire.item.required
Definition | An indication, if true, that the item must be present in a "completed" QuestionnaireResponse. If false, the item may be skipped when answering the questionnaire.
Short | Whether the item must be included in data results
Comments | If the required item is a question, it must have a direct answer (i.e. an answer to the question itself, not merely answers to child questions) in order for the QuestionnaireResponse to be complete. If the required item is a group, it must have at least one descendant question which has an answer Questionnaire.item.required only has meaning for elements that are conditionally enabled with enableWhen if the condition evaluates to true. It also only has meaning if the parent element is present. If a non-required 'group' item contains a 'required' question item, it's completely fine to omit the group (because it's not required) despite it having a required child. Similarly, if an item that contains other items is marked as required, that does not automatically make the contained elements required (though required groups must contain at least one descendant item with a populated answer). The value for 'required' may come from the ElementDefinition referred to by .definition.

126. Questionnaire.item.repeats
Definition | An indication, if true, that a QuestionnaireResponse for this item may include multiple answers associated with a single instance of this item (for question-type items) or multiple repetitions of the item (for group-type items).
Short | Whether the item may repeat
Comments | If a question is marked as repeats=true, then multiple answers can be provided for the question in the corresponding QuestionnaireResponse. When rendering the questionnaire, it is up to the rendering software whether to render the question text for each answer repetition (i.e. "repeat the question") or to simply allow entry/selection of multiple answers for the question (repeat the answers). Which is most appropriate visually may depend on the type of answer as well as whether there are nested items. The resulting QuestionnaireResponse will be populated the same way regardless of rendering - one 'question' item with multiple answer values. The value may come from the ElementDefinition referred to by .definition. When repeats=true for a group, it'll be represented with multiple items with the same linkId in the QuestionnaireResponse. For a question, it'll be represented by a single item with that linkId with multiple answers.

128. Questionnaire.item.readOnly
Definition | An indication, when true, that the value cannot be changed by a human respondent to the Questionnaire.
Short | Don't allow human editing
Comments | If specified on a 'group', then all items beneath the specified group are read only. For questions, this only marks the answer associated with the specific item read only. Descendant questions are not impacted. The value of readOnly elements can be established by asserting extensions for defaultValues, linkages that support pre-population and/or extensions that support calculation based on other answers.
