Final answer:
SNOMED-CT is a comprehensive healthcare terminology system used to consistently capture, share, and aggregate clinical data, complementing WHO's ICD for detailed clinical information handling.
Step-by-step explanation:
The Systematized Nomenclature of Human and Veterinary Medicine Clinical Terms (SNOMED-CT) is a comprehensive, multilingual healthcare terminology used globally. It facilitates the exchange and aggregation of clinical data across specialties and sites of care. By providing a consistent way to index, store, retrieve, and aggregate clinical data across specialties and sites of care, the SNOMED-CT enables a consistent way of capturing, sharing, and aggregating health data across clinical care and research, which assists in the detailed documentation of clinical care, facilitates evidence-based healthcare, and provides data for research and public health reporting.
SNOMED-CT, similar to the International Classification of Diseases (ICD), which is promoted by the World Health Organization (WHO) for classifying diseases and related health problems, provides a necessary level of specificity and scalability the complexities of clinical information handling. However, SNOMED-CT is much more granular and offers more than just disease and condition codes, encompassing a wide array of clinical concepts like clinical findings, symptoms, diagnoses, procedures, organisms and substances.
