Objective,2,To compare the differences between the International Classification of Traditional Medicine (ICTM) in the ,Eleventh Revision of International Classification of Diseases, (ICD-11) and the new editions of Traditional Chinese Medicine (TCM) National Standards, and promote the application of ICTM and the new editions of TCM National Standards.,Methods,2,Relational mappings were created for identifying differences between ICTM and the new editions of TCM National Standards from the aspects of inclusion scope, coding rules, and classification system through mathematical statistics, text comparison, and literature analysis.,Results,2,In respect of inclusion scope: ICTM and the new editions of TCM National standards have 169 common terms of diseases and 196 common terms of syndromes, but they actually share the remaining 141 terms of diseases and 175 terms of syndromes in common after excluding invalid codes. In respect of coding rules: In ICTM, Y and Z are used separately to mark "other specific" terms and "unspecified" terms, and a single column is used to mark valid codes, invalid codes and other rules; The new editions of TCM National Standards use a dot "." to indicate the classification hierarchy of terms, and the category attribute of each term is identified by the dot "." at the end of the code. In respect of classification system: Compared with ICTM, the new editions of TCM National Standards are more comprehensive in disease and syndrome classification system, which basically cover the syndrome classification system of ICTM.,Conclusions,2,There is significant difference in the number of terms included in ICTM and the new editions of TCM National Standards, and ICTM does not include terms of treatment. In respect of term compilation, classification and definition, the new editions of TCM National Standards either basically cover ICTM terms, or create relational mappings with ICTM terms.
