{description: 'The Next Question operation is used for *adaptive questionnaires* - forms where the next question (or set of questions) is based on previous answers.  The result of this operation is to return an updated QuestionnaireResponse with a contained Questionnaire that includes the next question (or set of questions).  It might also include display items with instructions and/or read-only questions containing calculated scores.  This operation uses the [QuestionnaireResponse](http://hl7.org/fhir/R4/questionnaireresponse.html) resource with a [*contained*](http://hl7.org/fhir/R4/references.html#contained) [Questionnaire](http://hl7.org/fhir/R4/questionnaire.html) as both the input and output parameter. The client initiates and queries for the next question by including the answers to all required questions in the questionnaire to that point.  The Server updates the contained Questionnaire in the QuestionnaireResponse in the with the next question or set of questions and any needed instruction or score items.  When the questionnaire is complete, the Server updates the `QuestionnaireResponse.status` resource parameter to `complete`.  If completion of the questionnaire has exceeded any time limit, the Server may return an [OperationOutcome](http://hl7.org/fhir/R4/operationoutcome.html) with an error.', package_name: hl7.fhir.uv.sdc.r4b, name: SDCNextQuestion, type: 'true', package_version: 3.0.0, class: operation, kind: operation, url: 'http://hl7.org/fhir/uv/sdc/OperationDefinition/Questionnaire-next-question', version: 3.0.0}
