1 | LOINC timeline changes - please refer to Roadmap link here LOINC | July 2018 and potentially other future releases. |
2 | Revision of IS A relationships for anatomy concepts The new anatomy concept model has implemented the new Description Logic features, e.g. reflective and transitive property, general concept axioms, for consistent logical modeling. However, the new model cannot be implemented in production because these DL features currently are not available in production. The implementation of them will depend on the enhanced logic profile for SNOMED CT which is under development by the Modeling AG. Yet, the inferred IS A relationship from the OWL anatomy ontology can be reviewed and implemented in the production. This will utilise the outcomes of the new anatomy model as well as evaluate the design of the new model. In particular, it is important to review the changes of IS-A relationships in anatomy for quality assurance and minimise impact to other hierarchies, such as disorders, procedures, observables, situations etc. The first subject area for revision is the sub-hierarchy of skin structure. The majority changes have been made in the January 2018 release. The rest will be completed in July 2018 release. For July 2018 release, the subject area for revision of IS A relationships will be determined and updated in the following confluence page. | July 2018 International Edition |
3 | Summary of Drugs changes New hierarchies 766940004 | Role (role) and subhierarchy 766941000 | Therapeutic role (role) created with additional subtypes to be added in future releases New semantic tags (role) Attribute types New attributes created:
Grouper concepts representing disposition, intended site, and/or structure Grouper concepts representing disposition, intended site, and/or structure sufficiently defined by modeling to proximal primitive concept, adding defining attributes, and updating descriptions per editorial guidelines (n≈550). New high level grouper concepts created as an incremental improvement with additional subtypes to be added in future releases:
Product role concepts Concepts representing product role relocated as stated descendants of 763087004 | Medicinal product categorized by role (product) with definition status = primitive and attributes inactivated (n≈ 400) For further details see Briefing Note Use of Additional Axiom Functionality and Remodeling Product Roles Medicinal product (MP) concepts - MP-containing concepts sufficiently defined by modeling to proximal primitive concept, adding defining attributes, and updating descriptions per editorial guidelines (n≈ 3750). Includes the following attributes:
Medicinal product form (MPF) concepts - MPF-containing concepts sufficiently defined by modeling to proximal primitive concept, adding defining attributes, and updating descriptions per editorial guidelines (n≈2100). Includes the following attributes:
Clinical drug (CD) concepts - CD-containing precisely concepts sufficiently defined by modeling to proximal primitive concept, adding defining attributes, and updating descriptions per editorial guidelines (n≈ 4850). Includes the following attributes:
Documentation Notification for Briefing Notes, Editorial Guidelines, and other documentation updates are posted on the project group website as they become available; see Drug Model Working Group - Directory for details Briefing Briefing note - Use of Additional Axiom Functionality and Remodeling Product Roles.pdf | July 2018 International Edition |
4 | Summary of Substances Changes Dietary subhierarchy. To remove context of use from the substance concepts and manage the situation where substances can be both a pharmaceutical ingredient and a foodstuff (n≈80) that had a tag of “- dietary” in the Fully Specified Name (FSN) and the Preferred Term (PT) were inactivated. Replacement concepts concept without "-dietary" in the FSN and PT were created. The top level concept "Dietary substance (substance)" has been inactivated and replaced with a new concept "Edible substance (substance)". Radioactive isotope substances. These concepts have been remodelled and the terming normalised to provide consistent representation without the use of carats. Cancer related substance. The subhierarchy has now been removed. Some concept have been inactivated. Some have been moved within the substances hierarchy. Disposition Groupers
Structural Groupers
Combined Groupers (Structure + Disposition)
Role Groupers
The "Is modification" of attribute has been implemented (n≈1200) resulting in flattening of the substances hierarchy. Overall 447 new concepts added to the substances hierarchy. Just over 460 substance concepts have been inactivated in the July 2018 SNOMED CT release. Documentation Notification for Briefing Notes, Editorial Guidelines, and other documentation updates are posted on the project group website as they become available; see Project Status Substance Hierarchy for details. | July 2018 International Edition |
5 | Internal QA Test and procedure status: Inactivated 143 concepts in the Situations and Findings hierarchies with pattern "Test/procedure OFFERED" and "Test/procedure NOT OFFERED" as these represent an administrative status. | |
6 | Internal QA Inactivation of Agencies and organizations (qualifier value) and subtypes: moved to UK extension i.e. 66 concepts inactivated. | |
