Internationally, it is a priority to develop and implement semantically interoperable health information systems.[1] One required technology is the use of standardised clinical terminologies. The terminology, SNOMED CT, has shown superior coverage compared to other terminologies in multiple clinical fields. The aim of this paper is to analyse SNOMED CT implementation in an Electronic Health Record (EHR). More specifically, differences and consequences of applying clinical findings (CFs) as an alternative to observable entities (OEs) is analysed. Results show that CFs represents the content of the templates with better coverage, with more parent concepts and with a higher degree of fully defined terms than the OEs. We discuss the possibility to further evaluate the observable entity hierarchy to overcome a potential overlapping use of the two hierarchies.
在国际上，开发和实施语义互操作的健康信息系统是一项优先任务。[1] 一项所需技术是使用标准化临床术语。术语SNOMED CT在多个临床领域已显示出比其他术语更好的覆盖范围。本文旨在分析SNOMED CT在电子健康记录（EHR）中的实施情况。更具体地说，分析了将临床发现（CFs）作为可观察实体（OEs）的替代方案所产生的差异和后果。结果表明，与OEs相比，CFs能以更好的覆盖范围、更多的父概念以及更高程度的完全定义术语来表示模板内容。我们讨论了进一步评估可观察实体层次结构以克服两个层次结构潜在重叠使用的可能性。
