The programming language Arden Syntax is especially adapted to the needs of computer-based clinical decision support. Recently, an extension of Arden Syntax, named Fuzzy Arden Syntax, was proposed by the authors. Fuzzy Arden Syntax is a conservative extension of Arden Syntax and offers special functionality to process gradual information. The background is the observation that in medicine we frequently deal with statements which are neither clearly false nor clearly true but hold to some intermediate degree. In this paper, we demonstrate under which circumstances a Medical Logic Module (a program unit written in Arden Syntax) may show unintended behavior and how the situation can easily be improved by means of the possibilities offered by Fuzzy Arden Syntax. To this end, an example from the domain of nosocomial infection control is discussed in detail.
编程语言Arden语法特别适合基于计算机的临床决策支持的需求。最近，作者提出了Arden语法的一种扩展，称为模糊Arden语法。模糊Arden语法是Arden语法的一种保守扩展，并提供了处理渐进信息的特殊功能。其背景是观察到在医学中，我们经常处理既不是明显错误也不是明显正确而是在某种中间程度上成立的陈述。在本文中，我们展示了在何种情况下医学逻辑模块（用Arden语法编写的程序单元）可能会表现出意外行为，以及如何借助模糊Arden语法提供的可能性轻松改善这种情况。为此，详细讨论了医院感染控制领域的一个示例。
