  SNOMED Historical Perspectives

 

Updated November 26, 2008

SNOMED Terminology Solutions, a division of the College of American Pathologists, was created upon the launch of the International Health Terminology Standards Development Organisation (www.ihtsdo.org). SNOMED Terminology Solutions was formerly known as SNOMED International. It achieved many significant milestones from the early development of the Systemized Nomenclature of Medicine to the breakthrough releases of SNOMED Reference Terminology (SNOMED RT) and SNOMED Clinical Terms (SNOMED CT).

SNOMED Milestones 1965-2005

History of Creating a World Class Terminology

For more than 40 years, the College of American Pathologists invested in the research and development of SNOMED. It successfully evolved from a pathology-centric terminology that was distributed and used in print format to works delivered electronically and integrated into computer applications.

In 1995, the College began collaboration with Kaiser Permanente to revolutionize SNOMED’s structure to reflect the advances in medical informatics and the science of computing (e.g., the use of description logics, distributed development, relational database structures) in a desktop PC world. As a result, SNOMED RT was launched in May 2000.

SNOMED, with its roots in specialty medicine, ranked #1 in various third-party studies assessing terminology options. The United Kingdom’s READ Codes, with its origin in primary care, typically ranked second. Thus to achieve world class terminology status and conserve the limited global supply of medical terminology expertise, the College and the UK Minister of Health agreed to combine the College's SNOMED RT with the UK’s Clinical Terms Version 3 (formerly known as the READ Codes) to create SNOMED CT. SNOMED CT, first released in January 2002, combined SNOMED RT's strengths in the basic sciences, laboratory and specialty medicine with the richness of the UK’s work in primary care. The end result was a comprehensive and precise clinical reference terminology that provides unsurpassed clinical content and expressivity for clinical documentation and reporting.

SNOMED CT nearly doubled the content of SNOMED. It further expanded its technical infrastructure providing greater flexibility to localize content for specific use (e.g., develop subsets, create extensions, develop mappings to other works). Formal evaluation in the UK, cross validation by US and UK development teams, and external validation by more than 42 alpha test sites in six countries further refined the content.

Consistent with its strategy to become a world-class clinical terminology, various domain-specific vocabularies were systematically integrated into SNOMED (e.g., the nursing vocabularies, lab LOINC, SNODENT). Key classifications and data sets were mapped to SNOMED (e.g., ICD-9CM, ICD-10, ICD-O, PNDS) and alignment with leading messaging standards (e.g., HL7, DICOM, XML) was pursued.

Major Milestones in SNOMED’s Development include:
  • SNOP - 1965
  • SNOMED - 1974
  • SNOMED II - 1979
  • SNOMED Version 3.0 - 1993
  • LOINC codes integrated into SNOMED - 1997
  • SNOMED Version 3.5 - 1998
  • SNOMED RT - 2000
  • SNOMED CT (SNOMED RT + CTV3) - First release January 2002
  • SNOMED CT Spanish Edition - April 2002
  • SNOMED CT German Edition - April 2003

June 3, 2005
Federal Health IT Report Recognizes SNOMED CT

A June 3 report from the Department of Health and Human Services summarizes more than 500 responses to a Nov. 15, 2004, request for information (RFI) by the federal Office of the National Coordinator for Health Information Technology. The office issued the RFI to gather comment from organizations and individuals on how the federal government should develop and deploy national health information network (NHIN).

In its report, the HHS identifies SNOMED CT along with seven other medical coding and terminology systems that respondents recommended for a master list of standards that would provide a national baseline for electronic data exchange. The report notes that standards on the master list could function as “the bridge between custom implementations of other standards, where translations to/from the master set would facilitate health information exchange among health applications.” (Full report)
