Systematized Nomenclature of Medicine

For the collection of information officially organized with the SNOMED system, see SNOMED CT.

The Systematized Nomenclature of Medicine (SNOMED) is a systematic, computer-processable collection of

Read codes) to produce SNOMED CT.[2][3]

Versions of SNOMED released prior to 2001 were based on a multiaxial,

organ (anatomy), which results in a code in a topography axis and may lead to morphological
alterations represented by a morphology code.

In 2002 the first release of SNOMED CT adopted a completely different structure. A sub-type hierarchy, supported by defining relationships based on description logic, replaced the axes described in this article. Versions of SNOMED prior to SNOMED CT are planned to be formally deprecated from 2017.[5] Therefore, readers interested in current information about SNOMED are directed to the article on SNOMED CT.

Purpose

SNOMED was designed as a comprehensive nomenclature of clinical medicine for the purpose of accurately storing and/or retrieving records of clinical care in human and veterinary medicine. The metaphor used by

periodic table of elements of medicine because of its definitional organization beyond the hierarchical design. Indeed, diseases and procedures were ordered hierarchically and are further referenced back to more elementary terms[citation needed
]

History

SNOMED was originally conceived by Côté as an extension of the design of the Systematized Nomenclature of Pathology (SNOP) applicable for all medicine. SNOP was originally designed by Arnold Pratt to describe pathological specimens according to their morphology and anatomy (topography). The ambitious development of SNOMED required many more axes (see multi-axial design, below). SNOMED was jointly proposed for development to the

IHTSDO) acquired all the Intellectual Property of SNOMED CT and all antecedent SNOMED versions.[citation needed

Brief timeline:

Reference ontology

SNOMED was designed from its inception with complex concepts defined in terms of simpler ones. For example, a disease can be defined in terms of its abnormal anatomy, abnormal functions and morphology. In some cases, the etiology of the disease is known and can be attributed to an infectious agent, a physical trauma or a chemical or pharmaceutical agent.[citation needed]

Multi-axial design

The current concept uses eleven (11) axes that comprise terms organised in hierarchical trees. The axes and some examples are provided below:

T (Topography) – Anatomic terms

M (Morphology) – Changes found in cells, tissues and organs

For the Morphology axis, SNOMED has agreed to collaborate and use the same harmonized codes shared with International Classification of Diseases for Oncology. Additional examples on topology are provided on that page.

L (Living organisms) – Bacteria and viruses

C (Chemical) – Drugs

F (Function) – Signs and symptoms

J (Occupation) – Terms that describe the occupation

  • Kindergarten teacher (13420)
  • Computer programmer (08420)
  • Doctor (06105)
  • Professional Nurse (General) (07110)
  • Beautician (57040)

D (Diagnosis) – Diagnostic terms

P (Procedure) – Administrative, diagnostic and therapeutic procedures

A (Physical agents, forces, activities) – Devices and activities associated with the disease

S (Social context) – Social conditions and important relationships in medicine

G (General) – Syntactic linkages and qualifiers
