| Description | The US Edition of SNOMED CT combines the International Release of SNOMED CT and the US Extension of SNOMED CT SNOMED CT provides the core general terminology for the electronic health record (EHR). The concepts have unique meanings and formal logic-based definitions organized into hierarchies. Each International Release includes the core of the terminology (concepts, descriptions, and relationships), together with works to support the implementation and use of SNOMED CT, including subsets, cross maps to existing classifications and coding schemes, and an extensive set of guidelines. The US Extension to SNOMED CT included the concepts, descriptions, and relationships accepted by NLM as a formal extension to the SNOMED CT International Release. NLM no longer releases the standalone US Extension. The US Edition of SNOMED CT includes more than 300,000 unique concepts. There are over 1,000,000 descriptions in SNOMED CT, including synonyms that can be used to refer to a concept. In addition, there are approximately 903,000 links or semantic relationships between the SNOMED CT concepts. |

- CCC Nursing Ontology
- This is nursing diagnosis ontology of Clinical Care Classification
- Cardiac-centered Frailty Ontology
- This ontology is designed to cover the portions of reality relevant to assessing patient frailty. While we believe it to be relevant to frailty in general, during its development we were specifically focused on decisions relating to cardiac care. We gathered terms using existent instruments, physician interviews, and automated chart reviews. The hierarchical structure was taken from SNOMED-CT. We could not simply use SNOMED-CT because it is too exhaustive to be useful. We add entities where necessary to remain true to our data.
- Drug-Induce Liver Injury (combined)
- A SNOMED subset of terms related to histological and clinical descriptions of Drug Induced Liver Injury (DILI). See Wang et al., "A Unifying Ontology to Integrate Histological and Clinical Observations for Drug-Induce Liver Injury" The American Journal of Pathology, 182:4,1180-1187 (2013). This view contains both of the DILIo major branches; SNOMED:Body Structure and SNOMED:Clinical finding Some of the class names have been changed to correspond to the preferred names in SNOMED of 7/31/2011. In DILIo publication -> in this file; Disorder of liver -> Disease of liver; Finding of general form of body -> General form of body - finding; Finding of size of liver -> size of liver - finding; Subacute necrosis of liver -> subacute hepatic necrosis

- SNOMED CT Standard Ontology Based on the Ontology for General Medical Science
- The Systematized Nomenclature of Medicine Clinical Term Ontology (SCTO) attempts to create a basic OWL 2 ontology for SNOMED CT terminology. The ontology is built based on the Ontology of General Medical Science (OGMS). This ontology implements the SNOMED CT concept model by adding the appropriate axioms to its top-level concepts. The resulting ontology can prevent redundancies and inconsistencies in this large terminology. Moreover, the terminology maintenance can become more accurate. Finally, SNOMED CT can be used in a healthcare environment to create more complex post-coordinated expressions and constraints in a more accurate manner.
