Concurrent validity of a rule-based system.
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.
