The purpose of this project was to test the concurrent validity of the diagnoses recommended by a rule-based expert system. Concurrent validity was determined first by comparing the expert system's computerized diagnostic recommendations with that of a Clinical Nurse Specialist (CNS Assessor) who assessed the patient, and secondly by comparing the expert system's candidate diagnoses with those of a panel of 10 clinical nurse specialists (CNS Panel). The expert system rule base for generating diagnoses was programmed for some of the most common nursing diagnoses (Metzger & Hiltunen, 1987) including: alteration in comfort, acute pain; impaired physical mobility; sleep pattern disturbance; impairment of skin integrity and self-care deficit (bathing, feeding, toileting, and dressing). Activity intolerance and potential for infection were also programmed as diagnostic possibilities in the rule base.
本项目的目的是测试基于规则的专家系统所推荐诊断的同时效度。首先，通过将专家系统的计算机化诊断建议与评估患者的临床护理专家（CNS评估员）的诊断建议进行比较来确定同时效度；其次，将专家系统的候选诊断与由10名临床护理专家组成的小组（CNS小组）的诊断进行比较。用于生成诊断的专家系统规则库针对一些最常见的护理诊断进行了编程（梅茨格和希尔图宁，1987年），包括：舒适度改变、急性疼痛；身体活动能力受损；睡眠模式紊乱；皮肤完整性受损和自理缺陷（洗澡、进食、如厕和穿衣）。活动耐力下降和感染可能性也在规则库中被编程为诊断可能性。
