Value Sets

Value Sets

This page describes the ValueSets of the PRO module (naming convention MII_VS_<Module>_<Name>). For general guidance on using codes, see FHIR Terminology; the code systems the sets draw from are described on the Code Systems page.

Expansions: ValueSet expansions in this guide are produced by a FHIR terminology server — SU-TermServ if the client certificate is configured, otherwise the public HL7 server tx.fhir.org (in which case some KDS-specific ValueSets may not expand completely).

SNOMED CT is used to identify instruments — assessment-scale concepts such as 273446001 (EORTC QLQ-C30) or 273524006 (HADS) — not for answer scales. The edition and version follow the KDS-wide Terminology Version Policy of the meta module; this module pins no SNOMED edition of its own. Expansion parameters are pinned centrally via the module's expansion manifest.

The answer scales are MII-controlled ValueSets over the module's own CodeSystems: each answer concept carries its scoring weight as an itemWeight property, which is what makes the calculated expressions (.weight()) reliable — the core of the module's terminology strategy.
