Properties

This code system defines the following properties for its concepts

Name	Code	URI	Type	Description
Not Selectable	notSelectable	http://hl7.org/fhir/concept-properties#notSelectable	boolean	Indicates that the code is abstract - only intended to be used as a selector for other concepts

Concepts

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

Lvl	Code	Display	Definition	Not Selectable	Copy
1	group	Group	An item with no direct answer but should have at least one child item.
1	display	Display	Text for display that will not capture an answer or have child items.
1	question	Question	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).	true
2	boolean	Boolean	Question with a yes/no answer (valueBoolean).
2	decimal	Decimal	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	integer	Integer	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	date	Date	Question with a date answer (valueDate).
2	dateTime	Date Time	Question with a date and time answer (valueDateTime).
2	time	Time	Question with a time (hour:minute:second) answer independent of date. (valueTime).
2	string	String	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	text	Text	Question with a long (potentially multi-paragraph) free-text entry answer (valueString).
2	url	Url	Question with a URL (website, FTP site, etc.) answer (valueUri).
2	coding	Coding	Question with a Coding - generally drawn from a list of possible answers (valueCoding)
2	attachment	Attachment	Question with binary content such as an image, PDF, etc. as an answer (valueAttachment).
2	reference	Reference	Question with a reference to another resource (practitioner, organization, etc.) as an answer (valueReference).
2	quantity	Quantity	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.
