A QuestionnaireLinkage links questions across questionnaires or questionnaire versions, so that application systems can juxtapose answers from different QuestionnaireResponses — for example a child's answer about their own condition shown side by side with a parent's answer to the corresponding question about the child.
A QuestionnaireLinkage is a defining artifact: like plan definitions and questionnaires it is searchable and readable for all users holding the required privileges, while maintenance is anchored in organisational ownership.
The profile is based on FHIR Basic, following the same construction as ehealth-view and
ehealth-actionguidance. Instances are discriminated by both meta.profile and Basic.code
(questionnairelinkage from CodeSystem http://ehealth.sundhed.dk/cs/basic-resource-type).
The linkage consists of:
description and
linkage entries, each pairing a questionnaire reference with the linkId of the linked question in
that questionnaire. A group may span two or more questionnaires, need not cover all questionnaires in
the linkage, and may link questions within a single questionnaire.ehealth-view: recommendation, intendedAudience, modifierRole
(owner/co-author Organization), title, version, description, purpose, useContext and status.Basic.code is fixed to http://ehealth.sundhed.dk/cs/basic-resource-type#questionnairelinkage.
Every QuestionnaireLinkage carries an identifier with a random UUID value (urn:uuid: prefix, system
urn:ietf:rfc:3986), assigned at creation and immutable, providing traceability across environments.
Plan templates designate intended linkages per questionnaire activity via the
ehealth-intendedQuestionnaireLinkage extension on PlanDefinition.action; the $apply operation copies
the designation onto the created ServiceRequests.
A linkage connecting the systolic blood pressure question across two business versions of a blood pressure questionnaire:

Status uses the ehealth-status extension bound to the standard publication-status ValueSet. Allowed
transitions: draft → active, draft → retired, active → retired. A retired linkage is immutable. There is no
entered-in-error state, no delete (a draft created by mistake is retired instead) and no versioning support
(no predecessor/base lineage and no server-side version handling; the version extension is plain
author-maintained metadata).
A QuestionnaireLinkage can only be set to active when it references at least one questionnaire in
questionnaireLinkageFor.
| Element group | draft | active / retired |
|---|---|---|
| status, intendedAudience, useContext, modifierRole, recommendation | editable | editable |
| title, description, version, purpose | editable | locked |
| questionnaireLinkageFor, item (defining content) | editable | locked |
| identifier | immutable | immutable |
Updates additionally require the user's organisational context to match the linkage's modifierRole (owner/co-author); changes to the modifier roles themselves are reserved for the owner.
On create and update the following is rejected:
questionnaireLinkageFor or item.linkage that does not exist,item.linkage.questionnaire that is not among the questionnaireLinkageFor references,item.linkage.linkId that does not exist in the referenced questionnaire,questionnaireLinkageFor is empty.QuestionnaireLinkage resources can be searched by:
title (string — startsWith matching, case- and accent-insensitive; :contains is not supported)questionnaireLinkageFor (reference — linkages relevant for given questionnaires)status (token), reference (modifier role reference), intendedAudience (reference) and
recommendation (token)context, context-type and context-type-value parameterscode, identifier, _id and _lastUpdated parametersAs all Basic-based profiles share one search space, searches should carry a profile or code discriminator.
