Naming Conventions for refsets

Qualitative vs Quantitive

Qualitative content that references ordinal answers for commonly used questions (e.g. urine glucose = 1-4+, wound discharge = scant to large, etc.) should reference an authoritative source that provides unambiguous (e.g. quantitative) meanings for the content. If there are no such sources, then the content ideally should be somehow annotated to give unambiguous, definite meanings to the concepts. Example - Wound exudate qualitative amount refset

Causative Agent Refset

We can start with using a subset of the range of the SNOMED CT attribute “Causative Agent” (i.e. descendants of Organism 410607006 and descendants of Physical object 260787004). As work continues with this refset, that range of content may be specialized further or expanded as necessary. Example - Causative Agent Refset
