Cost-effective health care is at the forefront oftoday's important health-related issues. A research teamii at the University ofPittsburgh has been interested in lowering the cost ofmedical care by attempting to define a subset of patients with comnmtnunity-acquired pneumionia for whoin outpatient therapy is appropriate and safe. Sensitivity and specificity requirementsfor this domain make it difficult to use rule-based learning algorithmtis with standard mteasures of performtance based on accuracy. This paper describes the use of misclassification costs to assist a rule-based machinelearningprogramii in deriving a decision-support aidfor choosing outpatient therapy for patients wsith community-acquiredpneumnonia.
