Actions log
| Item | Description | Owner | Notes | Action |
|---|---|---|---|---|
| 1 | April 2025 business meeting session for this group | KN / JC | At that face-to-face session would be beneficial to tackle some primary issues | Karim to follow up with Jim Campbell |
| 2 | UK need to consider whether inheres_in is superfluous in lab result reporting and align with international terminology | KN / AP | We agree it does not add anything but need to add to internal UK NRC log for discussion | On hold |
| 3 | Time aspect modelling | KN / AP | modelling single point in time explicitly to enable correct classification of content Internal UK NRC log for discussion | Daniel to give a short presentation on time aspect - needs further discussion On hold Discussed with lab experts and the requirement is the same as the LOINC Ontology - time-specific concepts must not be subsumed by unmodelled soft default implicit 'single point in time' concepts |
| 4 | SARS-Cov2 observable entity concepts for reporting viral RNA presence in the SNOMED CT International Edition | FA | These concepts are modelled with both inheres_in and direct_site | Farzaneh to take these back and discuss internally for a steer on the use of inheres_in for these concepts |
| 5 | Use of inheres_in for colour, appearance, identification | FA | inheres_in used for the property to describe the characteristic of an organism, cell or body structure - applicable to LOINC Ontology representations | Farzaneh to present examples to group at a future session |
| 6 | Representation of percent | FA / SH | Discussion page on the LOINC Ontology dev side for the percent vs 'per 100 cells' and feedback to the group | |
| 7 | Fractions and ratios | All | IFCC-IUPAC Silverbook https://iupac.org/what-we-do/books/silverbook/ but also on the homepage: https://labterminology.com/list-of-kinds-of-property/ | Proposed to revisit after reviewing the resources |
| 8 | Relative concentration of a substance in two different specimens Relative concentration two different measurement properties | KN / DK | How do we assess effort vs impact? The requirement to model them accurately for machine reasoning - auto-classifications; erroneous subsumptions | Karim to review the modelling options with Daniel and bring back to the group |
Issues and decisions log
| Item | Description | Owner | Notes | Decision |
|---|---|---|---|---|
| 1 | Time aspect specification in description AND modelling | All | Concept is primitive if the description is more specific than the modelling. Concept logical definition must not be more specific than concept description | Must be stated consistently in description AND modelling in accordance with SI editorial policy |
| 2 | Inheres_in is superfluous in lab result reporting | All | Inheres_in effectively duplicates direct_site. They are two different perspectives (lab and clinical) of the same target | Direct_site attribute sufficiently captures specimen and derivable substance |
| 3 | Representation of percent | All | Concept is primitive if the description is more specific than the modelling. Concept logical definition must not be more specific than concept description | Represent percent in the description and the unit in SNOMED CT in accordance with SI editorial policy - provisional decision? |
| 4 | Inconsistencies - International content for cancer synoptic reporting by immunohistochemistry 1255078008 | Percent of cell nuclei positive for proliferation marker protein Ki-67 in primary malignant neoplasm by immunohistochemistry (observable entity) | | All | Does not use percent unit in modelling e.g. 1 - modelling time_aspect -> single point in time but not stating this in the description In contrast to LOINC Ontology examples that do state 'at single point in time' in the description and model in the logic e.g.2 - use inheres_in whereas LOINC Ontology used direct_site | |
