SNOMED CT: A Multilingual Terminology System for Clinical Healthcare and Interoperability

Details

SNOMED CT (Systematized Nomenclature of Medicine - Clinical Terms) is a massive, multilingual clinical terminology set used to systematically represent concepts such as diseases, findings, procedures, and tests in clinical medicine. It serves as a foundational technology supporting international interoperability. Crucially, it is utilized alongside structural standards like FHIR. This combination allows for the unified representation of meaning (semantics) within clinical information. The text clarifies that while LOINC handles 'measurements,' SNOMED CT covers general 'clinical concepts.' The related news section highlights practical implementation and usage trends, including preventing hallucinations in coding AI using FHIR Terminology Service and MCP, and web series on creating questionnaires with SNOMED CT and FHIR. This demonstrates its active role in real-world healthcare IT applications. The standard is promoted by the international organization, SNOMED International.
