Systematized Nomenclature of Medicine-Clinical Terms (SNOMED-CT) is considered to be the most comprehensive, multilingual clinical healthcare terminology in the world. Each year, avoidable deaths and injuries occur because of poor communication between healthcare practitioners, or because busy practitioners forget or neglect to follow their own criteria for best practices. The delivery of a standard clinical terminology for use across the world's health information systems can therefore make a significant contribution towards improving the quality and safety of healthcare.

SNOMED CT aims to contribute to the improvement of patient care through underpinning the development of systems to accurately record health care encounters and to deliver decision support to health care providers. SNOMED CT was originally created by the College of American Pathologists.
