Technical Guidelines
Format of Questionnaire linkId
A FHIR Questionnaire uses a string-based Questionnaire.item.linkId to identify the individual questionnaire groups and questions. This linkId is also referred from the FHIR QuestionnaireResponse.
- linkId shall be assigned a value on the form “<root>,<extension>,<assigningAuthorityName>”. Here, <root> shall be an Object Identifier (OID) (See definition on https://www.hl7.org/Oid/information.cfm). The linkId for the example below would be “1.2.208.176.1.5.1,220,Sundhedsdatastyrelsen”
.
In case a QuestionnaireResponse must be transferred to the national IHE XDS-based document sharing infrastructure, it is assembled into a document and transformed to a Questionnaire Response Document adhering to the DK-HL7 QRD profile. In this document, the question identifier is on the Instance Identifier form for which an example is given below:
<id assigningAuthorityName="Sundhedsdatastyrelsen" extension="220" root="1.2.208.176.1.5.1"/>
Using the comma encoded form described for the linkId above in FHIR Questionnaire and QuestionnaireResponse, the question identifier can be handled when transforming to and from FHIR.
