TLDR

SNOMED Clinical Terms is being created by merging SNOMED RT and Clinical Terms Version 3, a collaboration between the College of American Pathologists and the UK National Health Service, both of which bring extensive terminology development experience. The paper outlines the development process and current status of SNOMED CT, detailing how the combined resources and expertise of the two organizations are applied. Preliminary merger outcomes include mapping between the two systems, integration of their upper‑level hierarchies, and harmonization of attributes.

Abstract

Two large health care reference terminologies, SNOMED RT and Clinical Terms Version 3 , are in the process of being merged to form a comprehensive new work referred to as SNOMED Clinical Terms. The College of American Pathologists and the United Kingdom s National Health Service have entered into a collaborative agreement to develop this new work. Both organizations have extensive terminology development and maintenance experience. This paper discusses the process and status of SNOMED CT development and how the resources and expertise of both organizations are being used to develop this new terminological resource. The preliminary results of the merger process, including mapping, the merger of upper levels of each hierarchy, and attribute harmonization are also discussed.
