SNOMED CT

SNOMED Clinical Terms (SNOMED CT) is the most comprehensive, multilingual clinical healthcare terminology in the world. 

SNOMED CT contributes to the improvement of patient care by underpinning the development of Electronic Health Records that record clinical information in ways that enable meaning-based retrieval. This provides effective access to information required for decision support and consistent reporting and analysis. Patients benefit from the use of SNOMED CT because it improves the recording of EHR information and facilitates better communication, leading to improvements in the quality of care.

SNOMED CT is owned, maintained and distributed by the International Health Terminology Standards Development Organisation (IHTSDO). The IHTSDO is a not-for-profit association which is owned and governed by its national Members. In April 2014 twenty-seven countries were Members of IHTSDO, more countries are joining every year.
