It is important to understand and describe how nurses make diagnostic decisions. This article describes the process by which knowledge is acquired and represented in a rule-based expert system for nursing diagnosis. Knowledge acquisition was obtained by tapping the expertise of clinical nurse specialists who were able to articulate the elements present in their diagnostic decisions. Knowledge representation was achieved using a commercially-available software package. VP Expert (Berkeley, CA). The clinical nurse specialists contributed many of the heuristics in the determination of self-care deficit as a nursing diagnosis. Three models of rules for the determination of self-care deficit, bathing are provided. These models represent a method for discriminating between levels of patient dependence. A description of rules that define specific causes, such as immobility are also included. They will be tested in the clinical setting.
理解并描述护士如何做出诊断决策很重要。本文描述了在基于规则的护理诊断专家系统中知识获取和呈现的过程。通过挖掘临床护理专家的专业知识来获取知识，这些专家能够阐明其诊断决策中存在的要素。使用商业软件包VP Expert（加利福尼亚州伯克利）来实现知识表示。临床护理专家在确定自我护理缺陷作为护理诊断方面贡献了许多启发法。提供了三种确定自我护理缺陷（沐浴方面）的规则模型。这些模型代表了一种区分患者依赖程度的方法。还包括定义特定原因（如活动不便）的规则描述。它们将在临床环境中进行测试。
