Concepts such as symptoms present specific representational challenges in the EMR. This is because concepts without clear boundaries and external referents such as physical objects can only be examined against other terminology-based concept representation systems. The truth and falsity of such concept representation is therefore relative to the terminology-based systems. Using the concept of acute postoperative pain as an example, we examined three terminology based approaches to representing the concept. Widely varying coverage across existing clinical terminologies was evident, although the common clinical approach to reporting attributes of symptoms provided a useful organizational structure and should be examined in relation to developing terminology and information models.
诸如症状之类的概念在电子病历中呈现出特定的代表性挑战。这是因为像物理对象那样没有明确边界和外部参照的概念，只能对照其他基于术语的概念表示系统来审视。因此，这种概念表示的真假相对于基于术语的系统而言。以急性术后疼痛这一概念为例，我们研究了三种基于术语来表示该概念的方法。尽管报告症状属性的常见临床方法提供了一种有用的组织结构，并且在开发术语和信息模型时应予以审视，但现有临床术语之间的覆盖范围差异很大是显而易见的。
