Expansion based on QuestionnaireItemType v5.0.0-cibuild (CodeSystem)

1  grouphttp://hl7.org/fhir/item-typeGroup

An item with no direct answer but should have at least one child item.

1  displayhttp://hl7.org/fhir/item-typeDisplay

Text for display that will not capture an answer or have child items.

1  questionhttp://hl7.org/fhir/item-typeQuestion

An item that defines a specific answer to be captured, and which may have child items. (the answer provided in the QuestionnaireResponse should be of the defined datatype).

2    booleanhttp://hl7.org/fhir/item-typeBoolean

Question with a yes/no answer (valueBoolean).

2    decimalhttp://hl7.org/fhir/item-typeDecimal

Question with is a real number answer (valueDecimal). There is an extension 'http://hl7.org/fhir/StructureDefinition/questionnaire-unit' that can be used to computably convey the unit of measure associated with the answer for use when performing data extraction to an element of type Quantity.

2    integerhttp://hl7.org/fhir/item-typeInteger

Question with an integer answer (valueInteger). There is an extension 'http://hl7.org/fhir/StructureDefinition/questionnaire-unit' that can be used to computably convey the unit of measure associated with the answer for use when performing data extraction to an element of type Quantity.

2    datehttp://hl7.org/fhir/item-typeDate

Question with a date answer (valueDate).

2    dateTimehttp://hl7.org/fhir/item-typeDate Time

Question with a date and time answer (valueDateTime).

2    timehttp://hl7.org/fhir/item-typeTime

Question with a time (hour:minute:second) answer independent of date. (valueTime).

2    stringhttp://hl7.org/fhir/item-typeString

Question with a short (few words to short sentence) free-text entry answer (valueString). Strings SHOULD NOT contain carriage return or newline characters. If multi-line answers are needed, use the 'text' type.

2    texthttp://hl7.org/fhir/item-typeText

Question with a long (potentially multi-paragraph) free-text entry answer (valueString).

2    urlhttp://hl7.org/fhir/item-typeUrl

Question with a URL (website, FTP site, etc.) answer (valueUri).

2    codinghttp://hl7.org/fhir/item-typeCoding

Question with a Coding - generally drawn from a list of possible answers (valueCoding)

2    attachmenthttp://hl7.org/fhir/item-typeAttachment

Question with binary content such as an image, PDF, etc. as an answer (valueAttachment).

2    referencehttp://hl7.org/fhir/item-typeReference

Question with a reference to another resource (practitioner, organization, etc.) as an answer (valueReference).

2    quantityhttp://hl7.org/fhir/item-typeQuantity

Question with a combination of a numeric value and unit as an answer. (valueSimpleQuantity) There are two extensions ('http://hl7.org/fhir/StructureDefinition/questionnaire-unitOption' and 'http://hl7.org/fhir/StructureDefinition/questionnaire-unitValueSet') that can be used to define what unit should be selected for the Quantity.code and Quantity.system.

Explanation of the columns that may appear on this page:

LvlA few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
