Several coding systems are commonly used in epidemiology. Some of the most prevalent include:
- International Classification of Diseases (ICD): Maintained by the WHO, this system is used worldwide to categorize diseases and health conditions. - SNOMED CT: A comprehensive clinical terminology that provides detailed coding for a wide range of medical terms. - LOINC: Primarily used for laboratory and clinical observations, this coding system standardizes medical test names and results.
Each of these systems serves a unique purpose and is used in different contexts depending on the specific needs of the study or health surveillance program.
