| 1 | April business meeting session for this group |
| - Agreement that a face-to-face session in April would be beneficial
- Specify a number of topics to discuss in person from the outputs of the virtual meetings
| Karim to follow up with Jim Campbell |
| 2 | How we apply the outputs from this group |
| - Follow SI governance process regarding inconsistencies in lab extension and specialism content and recommendations from the group
The group can recommend new editorial guidance to SI to meet user needs as long as they do not conflict with editorial policies This group should be working towards modelling lab observable entity content the same way
| Daniel to give a short presentation on time aspect - needs further discussion Create issues log and actions log |
| 3 | Relative concentration of a substance in two different specimens Relative concentration of two different measurement properties |
| How do we assess effort vs impact? The requirement to model them accurately for machine reasoning - auto-classifications; erroneous subsumptions Examples: Two different specimens LOINC 73913-6 - Glycine in CSF/Glycine in plasma UK SNOMED CT code 1812741000000102 | Substance concentration ratio of glycine in cerebrospinal fluid to glycine in plasma (observable entity) | Mass/Mol relative concentration 40486-3 Protein/Creatinine [Ratio] in 24 hour Urine Unit - g/mmol
Brief discussion on options and concept model limitations: We need to figure out the underlying ontological model that represents the dynamic for both use-cases - different specimens; different measured properties
| Karim to review the modelling options with Daniel and bring back to the group |
