Abstract：
OBJECTIVE: To explore the feasibility and challenges of mapping between SNOMED CT and the ICD-11 Foundation in both directions, SNOMED International and the World Health Organization conducted a pilot mapping project between September 2021 and August 2022.
METHODS: Phase 1 mapped ICD-11 Foundation entities from the endocrine diseases chapter, excluding malignant neoplasms, to SNOMED CT. In phase 2, SNOMED CT concepts equivalent to those covered by the ICD-11 entities in phase 1 were mapped to the ICD-11 Foundation. The goal was to identify equivalence between an ICD-11 Foundation entity and a SNOMED CT concept. Postcoordination was used for mapping to ICD-11. Each map was done twice independently, the results were compared, and discrepancies were reconciled.
RESULTS: In phase 1, 59% of 637 ICD-11 Foundation entities had an exact match in SNOMED CT. In phase 2, 32% of 1893 SNOMED CT concepts had an exact match in the ICD-11 Foundation, and postcoordination added 15% of exact match. Challenges encountered included non-synonymous synonyms, mismatch in granularity, composite conditions, and residual categories.
CONCLUSIONS: This pilot project shed light on the tremendous amount of effort required to create a map between the 2 coding systems and uncovered some common challenges. Future collaborative work between SNOMED International and WHO will likely benefit from its findings. It is recommended that the 2 organizations should clarify goals and use cases of mapping, provide adequate resources, set up a road map, and reconsider their original proposal of incorporating SNOMED CT into the ICD-11 Foundation ontology.

摘要：
目的：探讨SNOMEDCT与ICD-11基金会在两个方向上进行绘图的可行性和挑战，SNOMEDInternational和世界卫生组织在2021年9月至2022年8月之间进行了试点测绘项目。
方法：第1阶段绘制了内分泌疾病一章中的ICD-11基金会实体，排除恶性肿瘤，SNOMEDCT在第2阶段，SNOMEDCT概念与第1阶段ICD-11实体涵盖的概念等效，已映射到ICD-11基金会。目标是确定ICD-11基金会实体与SNOMEDCT概念之间的等效性。后协调用于映射到ICD-11。每张地图都独立做了两次，结果进行了比较，和差异被调和。
结果：在第一阶段，637个ICD-11基金会实体中有59％在SNOMEDCT中完全匹配。在第2阶段，1893年SNOMEDCT概念中有32％在ICD-11基金会中完全匹配，协调后增加了15%的完全匹配。遇到的挑战包括非同义词，粒度不匹配，复合条件，和剩余类别。
结论：这个试点项目揭示了在两个编码系统之间创建地图所需的巨大努力，并揭示了一些共同的挑战。SNOMED国际和世卫组织未来的合作工作可能会受益于其调查结果。建议这两个组织应明确映射的目标和用例，提供足够的资源，制定路线图,并重新考虑他们最初提出的将SNOMEDCT纳入ICD-11基金会本体的建议。
