SNOMED, the Systemized Nomenclature of Medicine, illustrates an all-inclusive default and validated medical terminology and concept terms for several different classifications which are arranged into nineteen hierarchies. The vocabulary promotes future advancements and supports evidence-based care (IHTSDO, 2016b). It also derives and processes these codes electronically to represent specific terms and concepts (Benson, 2012; Shortliffe & Cimino, 2014a). There were several predecessors before SNOMED CT, the current ontology version, that is utilized today. First came Systemized Nomenclature of Pathology (SNOP) created by pathologists, then SNOMED, and finally SNOMED CT. SNOMED CT evolved from merging Great Britain’s Real Clinical Terms with

Each element is recognized by an SNOMED CT Identifier (sctId) consisting of 6 to 18 digits. The sctId illustrates an irrelevant item identifier, a seven-digit namespace identifier that might be omitted), a two-digit partition identifier, and a single check digit. The namespace identifier represents local extensions. Extensions are additions to SNOMED to identify exclusive companies or countries. If the sctId lacks a namespace, then this connotes a section of the International Release of SNOMED CT (Benson, 2012). The partition identifier represents the type of component within the sctId. As previously stated, the partition identifier consists of two-digits. If the first digit is a zero, then the component belongs to the International Release. In contrast, if the first digit is a 1, then the component belongs to an extension set. The second digit within the partition identifier indicates what SNOMED element the sctId is classifying. For instance, if the second digit is a zero, it represents the concept; a 1indicates the description; a 2 represents the relationship; a 3 indicates a subset; a 4 represents a cross map set; and a 5 indicates a cross map target (Benson, …show more content…
Firstly, defining relationships define each concept in relation to connections with additional concepts. This can be employed for relationships that are eternally true. Defining relationships apply to the concept’s supertypes (i.e., the parents or defining attributes, or a combination of the two. Every defining relationships enumerate attribute-value pairs. Here, every attribute and value are also known as SNOMED concepts (Benson, 2012). Secondly, qualifying relationships are applied in post-coordinated expressions. This is an optional relationship which is non-defined. Moreover, it is difficult to use this relationship because SNOMED Concept Model is not flexible to permit this. Thirdly, the historical relationships offer a link to combine current replacement concepts with expired ones. Finally, additional relationships permit non-definitional altered information to be disseminated over
