- W1567693775 abstract "This research concerns an empirical assessment of methodologies for applying, evaluating and refining knowledge-based triage systems. Triage is the medical term for assigning degrees of medical severity to a patient's condition to allow physicians to prioritize available medical resources. Knowledge-based triage systems can support health care professionals in meeting challenges associated with rationing health care. This system concerned triage of upper respiratory infections (URI).The study explores the effects of a knowledge-based triage system on patients and care providers through a controlled clinical field study. The study measures the predictive validity of the triage knowledge base through statistical methods which consider site-specific clinical priorities. The study also evaluates models to assist care providers discover relationships in the patient case-base to refine triage protocols.The field study's results support the clinical utility of a knowledge-based triage system. Quality of care was not threatened by the presence of a computer in the examination room. The system provided a detailed record of patient symptoms, alerted care providers to possible drug interactions and assisted care providers in following a protocol's recommendations.The system responded appropriately to a diverse set of complicated URI patients, but the knowledge base was conservative in classifying patients with uncomplicated URI conditions. A fuzzy cluster model and a genetic classifier model revealed patterns in the patient case-base that could improve the accuracy of triage classifications. These refinement models allow physician designers the ability to explore patterns and to set explicit triage classification thresholds." @default.
