Systemized Nomenclature of Medicine - SNOMED
Systematized Nomenclature of Medicine
Is a multiaxial, hierarchical classification system. As in any such system, a disease may be located in a body organ which results in a code in a topography axis and may lead to morphological alterations represented by a morphology code. It systematically organize computer processable collection of medical terminology covering most areas of clinical information such as diseases, findings, procedures, microorganisms, pharmaceuticals etc. It allows a consistent way to index, store, retrieve, and aggregate clinical data across specialties and sites of care.
is a compositional concept system, which means that concepts can be specialised by combinations with other concepts. It is based on Description Logic and is designed so that content can be maintained as a dynamic resource.
SNOMED itself was started in 1965 as SNOP (Systematized Nomenclature of Pathology), and later extended into other medical fields.
SNOMED CT® (
erms) is considered to be the most comprehensive, multilingual clinical healthcare terminology in the world. SNOMED CT® was a joint development between the NHS in England and the College of American Pathologists (CAP) to develop an international clinical terminology and was formed in 1999 by the convergence of SNOMED RT and the United Kingdom's Clinical Terms Version 3 (formerly known as the Read Codes). It has greater depth and coverage of healthcare than the versions of Clinical Terms (Read Codes) that it replaces.
The oranization called International Health Terminology Standards Development Organisation(IHTSDO) are devoted acquire, own and administer the rights to SNOMED CT(® other health terminologies and/or related standards, and other relevant assets (collectively, the "Terminology Products").
