Details
This page functions as an HL7 FHIR CodeSystem reference, defining a set of concepts particularly associated with the Questionnaire Item Type. Its key feature is the structural description of various 'question' formats used for data collection. Specifically, it defines basic item types such as 'group', 'display', and 'question,' alongside diverse answer data types including: boolean (Yes/No), decimal (real number), integer, date, datetime, time, string, text, URL, and complex types like 'choice' or 'attachment'. These definitions form a foundational structure for mapping the diverse information collected in clinical settings to standard FHIR data types. This ensures interoperability when exchanging questionnaire data between different systems, enabling the creation and utilization of structured electronic health records and questionnaires.
