Summary

The Danish eHealth Infrastructure has released the 'upload-QFDD' operation definition, a feature built on FHIR standards. This specification details how to ingest Questionnaire Form Definition Documents (QFDD) into the system.

Details

This document is an artifact from the v3.5.1 release of the eHealth Infrastructure, which is based on the FHIR R4 standard. The operation definition 'upload-QFDD' specifies the process for uploading a specific type of Questionnaire Form Definition Document (QFDD) into the system. Technically, the input `DocumentReference` must be of type QFDD (74468-0) and have a status set to 'current'. The submission requires an attachment containing the base64 encoded QFDD XML document with `contentType` application/xml. Crucially, the QFDD XML document must contain a unique ID used as the `masterIdentifier` in the DocumentReference. The returned FHIR DocumentReference will carry the masterIdentifier, type, and description extracted directly from the attached QFDD document. This establishes a standardized method for integrating questionnaire form definition documents within the Danish electronic healthcare ecosystem, utilizing established FHIR standards.
