Concepts

This code system http://hl7.org/fhir/item-type defines the following codes:

Lvl | Code | Display | Definition | Not Selectable
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. |
