Term edits highlights:
- Through LOINC's collaboration with SNOMED International, 292 "Respiratory" System concepts were updated for improved modeling and representation of the System axis. Of those 292 concepts in LOINC, 17 concepts in pCLOCD had a name change in System.
- Work continues on the semi-quantitative clean-up project initiated by the LOINC Laboratory Committee in 2023. The semi-quantitative (SemiQn) scale was reintroduced for non-continuous measurement of numeric values. This new scale option has an impact on representation of Property. In LOINC 2.77, 40 concepts that had Property value "PrThr" and Scale “SemiQn” were reverted back to Scale "Ordinal" In pCLOCD, this change impacted 32 Challenge and 5 Chemistry concepts.
