Draft as of 2026-10-21 Responsible: The PreNUDGE Consortium Computable Name: AtPrenudgeQuestionnaireResponse

This FHIR profile is defining the overall Questionnaire Response for PreNUDGE. Be aware that if the user enters values from a device into a questionnaire, it is still considered a manual input. Please keep in mind that all questionnaire responses must comply with the qualification matrix on https://prenudge.at/qualificationmatrix/.
