Purpose/Significance To systematically evaluate the efficacy of the international classification of health interventions(ICHI) in the context of Chinese clinical terminology.Method/Process Based on the clinical terms of the cardiovascular circulatory system,the 5 dimensional information expression evaluation method is used to compare the performance of ICHI-WHO statistical version,ICHI-WHO extended version, ICHI local statistical version, ICHI local extended version and ICD-9-CM-3 in terms of terminology expression and loss.Result/Conclusion There are differences in the information expression performance of ICHI in different language terminology environments. In the Chinese clinical terminology environment, the terminology complete expression ratio of ICHI-WHO statistical version (47.0%) and extended version (59.2%) is higher than that of ICD-9-CM-3 (34.9%).After localization, ICHI’s information expression ability has been further improved, and ICHI local extended version performs the best (90.1%). Compared with ICHI-WHO and ICD-9-CM-3, the local version of ICHI in the context of Chinese clinical terminology has better information expression efficacy and can be promoted in China.
