ValueSet

Expansion performed internally based on codesystem Questionnaire Item Type v6.0.0-ballot3 (CodeSystem)

This value set contains 16 concepts

LevelSystemCodeDisplayDefinition
1 http://hl7.org/fhir/item-type   group Group An item with no direct answer but should have at least one child item.
1 http://hl7.org/fhir/item-type   display Display Text for display that will not capture an answer or have child items.
1 http://hl7.org/fhir/item-type   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).
2 http://hl7.org/fhir/item-type     boolean Boolean Question with a yes/no answer (valueBoolean).
2 http://hl7.org/fhir/item-type     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 http://hl7.org/fhir/item-type     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 http://hl7.org/fhir/item-type     date Date Question with a date answer (valueDate).
2 http://hl7.org/fhir/item-type     dateTime Date Time Question with a date and time answer (valueDateTime).
2 http://hl7.org/fhir/item-type     time Time Question with a time (hour:minute:second) answer independent of date. (valueTime).
2 http://hl7.org/fhir/item-type     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 http://hl7.org/fhir/item-type     text Text Question with a long (potentially multi-paragraph) free-text entry answer (valueString).
2 http://hl7.org/fhir/item-type     url Url Question with a URL (website, FTP site, etc.) answer (valueUri).
2 http://hl7.org/fhir/item-type     coding Coding Question with a Coding - generally drawn from a list of possible answers (valueCoding)
2 http://hl7.org/fhir/item-type     attachment Attachment Question with binary content such as an image, PDF, etc. as an answer (valueAttachment).
2 http://hl7.org/fhir/item-type     reference Reference Question with a reference to another resource (practitioner, organization, etc.) as an answer (valueReference).
2 http://hl7.org/fhir/item-type     quantity Quantity Question 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.

Explanation of the columns that may appear on this page:

Lvl A 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
Source The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
Display The 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
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
