Abstract
EvalHCID is a clinical decision support system integrating outbreak intelligence, symptom onset, and epidemiologic risk factors to identify high consequence infectious diseases (HCIDs) (eg, Ebola). Tested among 20 emergency department (ED) providers, it significantly reduced assessment time, lowered misclassification, and scored "excellent" usability. EvalHCID may improve institutional preparedness and patient outcomes for emerging infectious disease threats.
