Read Codes flowing lab data in UK are less computable and quite inaccurate lab test representations, and so they are being replaced with more accurate SNOMED CT logic and a FHIR pathology implementation guide LOINC was not computable and so will have corresponding ontological versions in the LOINC Ontology to make SNOMED CT versions available to anyone. Possibility of SNOMED CT international edition promotion for concepts that have global utility Lots of work done by Nebraska on interoperability and analytics; efforts put into the observables model with Daniel K setting up equivalence mapping and interop experiments. Referenced the previous LOINC-SNOMED CT expression refset NPU terminology - 30 years of implementation; not much happening from a national perspective. European users using LOINC and small corner of Europe using NPU. Going to explore how to use LOINC and NPU for interoperability and sharing health data. Using SNOMED CT for methods, specimen types, body structure components and result values - HL7 Europe published implementation guide. There will be an agreement with NPU to create a SNOMED CT extension and NPU mappings. SNOMED will be taking the same approach as we did with LOINC in that we are not doing mapping to the NPU terms. The NPU extension, like the LOINC extension, will be a transformation of the semantics of the NPU parts (which will be mapped to SNOMED equivalents) into a SNOMED concept model. The goal is complete semantic equivalence between terminologies. Possibility in this working group to discuss LOINC Ontology 'phase 2' modelling in comparing and reasoning our similarities and differences in logical modelling and selection of observable entity defining attributes in relation to descriptions per concept Possibility in this working group to work towards agreeing one SNOMED CT international concept instead of duplicating semantically and logically equivalent content in member / organisation extensions Investigating the scope for extending the observables concept model to represent more complex logic of patient test results |
