Concepts

This case-sensitive code system http://hl7.org/fhir/item-type defines the following codes in a Is-A hierarchy:

LvlCodeDisplayDefinitionNot Selectable
1group GroupAn item with no direct answer but should have at least one child item.
1display DisplayText for display that will not capture an answer or have child items.
1question QuestionAn 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).true
2\u00a0\u00a0boolean BooleanQuestion with a yes/no answer (valueBoolean).
2\u00a0\u00a0decimal DecimalQuestion 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\u00a0\u00a0integer IntegerQuestion 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\u00a0\u00a0date DateQuestion with a date answer (valueDate).
2\u00a0\u00a0dateTime Date TimeQuestion with a date and time answer (valueDateTime).
2\u00a0\u00a0time TimeQuestion with a time (hour:minute:second) answer independent of date. (valueTime).
2\u00a0\u00a0string StringQuestion 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\u00a0\u00a0text TextQuestion with a long (potentially multi-paragraph) free-text entry answer (valueString).
2\u00a0\u00a0url UrlQuestion with a URL (website, FTP site, etc.) answer (valueUri).
2\u00a0\u00a0coding CodingQuestion with a Coding - generally drawn from a list of possible answers (valueCoding)
2\u00a0\u00a0attachment AttachmentQuestion with binary content such as an image, PDF, etc. as an answer (valueAttachment).
2\u00a0\u00a0reference ReferenceQuestion with a reference to another resource (practitioner, organization, etc.) as an answer (valueReference).
2\u00a0\u00a0quantity QuantityQuestion with a combination of a numeric value and unit as an answer (i.e. a Quantity constrained to SimpleQuantity). 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.
