目的：作者评价了使用统一医学语言系统（UMLS）作为医疗知识来源的表示医疗程序在MAOUSSC system.Design：MAOUSSC，多轴编码系统，用于表示1500个程序，从15个临床专科，使用UMLS概念（增加了三个新的词汇表被添加到UMLS的全源）和关系，只要可能。UMLS的评价标准包括（1）概念和概念间关系表示的完整性，（2）概念和概念间关系分类的一致性，以及（3）可用性，包括UMLS对外语（法语）的适应性，其对具有不同于美国的医疗实践的地理区域的适用性，结果：在MAOUSSC试验期间，在增强的UMLS源中识别出的缺失概念或关系的数量被认为与总体项目目标无关。“失踪”UMLS概念间的关系被确定，虽然他们是小的。在数量上。UMLS中的一些不一致的地方，特别是在该地区的层次关系。结论：UMLS被用来作为一个知识源，代表1500复杂的医疗程序在MAOUSSC五年后，它的价值被认为是显着的。UMLS的未来版本有望提高概念间关系和全局一致性的表示。
Objective: The authors evaluated the use of the Unified Medical Language System (UMLS) as a medical knowledge source for the representation of medical procedures in the MAOUSSC system.Design: MAOUSSC, a multiaxial coding system, was used for the representation of 1500 procedures from 15 clinical specialties, using UMLS concepts (augmented by full sources for three new vocabularies being added to the UMLS) and relationships whenever possible. Evaluation criteria for the UMLS included (1) completeness of representation of concepts and of inter-concept relationships, (2) consistency in the categorization of both concepts and inter-concept relationships, and (3) usability, including adaptability of the UMLS to a foreign language (French), its suitability to a geographic region with different medical practices than the USA, and issues relative to the annual update changes in the test vocabularies.Results: During the MAOUSSC trial, the number of missing concepts or relationships identified in the augmented UMLS sources was deemed to be inconsequential relative to overall project goals. "Missing" UMLS inter-concept relationships were identified, although they were small. in number. Some inconsistencies in the UMLS were noted, especially in the area of hierarchic relationships.Conclusion: After UMLS was used for five years as a knowledge source for representing 1500 complex medical procedures in MAOUSSC, its value is considered significant. Future editions of the UMLS are expected to improve representation of inter-concept relationships and global consistency.
