SNOMED CT is a comprehensive biomedical vocabulary but has limitations in content coverage and data integrity. It is not sufficient alone as a healthcare organization's reference terminology.

Area of Science:

  • Biomedical Informatics
  • Health Terminology Standards

Background:

  • SNOMED CT is an extensive biomedical vocabulary formed by merging SNOMED RT and Read Codes V3.
  • It is widely considered for use as a reference terminology by various institutions.

Purpose of the Study:

  • To review the adequacy of SNOMED CT as a reference terminology.
  • To discuss challenges and limitations in its application as a primary reference terminology.

Main Methods:

  • Literature review and analysis of SNOMED CT's characteristics.
  • Examination of content coverage, data integrity, validity, and update frequency.

Main Results:

  • SNOMED CT exhibits limitations in content coverage across diverse clinical domains.

  • Issues concerning data integrity, validity, and update frequency were identified.
  • SNOMED CT alone is inadequate for serving as the sole reference terminology for healthcare organizations.
  • Conclusions:

    • While comprehensive, SNOMED CT requires supplementation to fully meet the needs of a healthcare organization's reference terminology.
    • Addressing identified limitations is crucial for effective implementation and utilization.
