Abstract: In China, the only available standard terminology system is the ICD-9-CM Chinese Edition. We performed this pilot study to evaluate the coverage of ICD and SNOMED CT CORE Subset based on standard terminologies that occur with high frequency in problem list data to facilitate the standardization of PLTs. After analyzed 165,959 problem list items without standardization including 17,437 unique terms, we found a distribution of a small proportion of commonly used terms and a long tail of rarely used ones. We used natural language processing methods to standardize and map terms into ICD and SNOMED CT CORE Subset and drew a conclusion of SNOMED CT CORE Subset is better than ICD for covering PLTs for clinical needs in China.

Learning Objective 1: To evaluate the coverage of ICD and SNOMED CT CORE Subset and identify a subset of concepts based on standard terminologies that occur with high frequency in problem list data to facilitate the standardization of PLTs in China.
