Gold Standard Evaluation of an Automatic HAIs Surveillance System

Table 4

Global confusion matrix InNoCBR VS gold standard with different types of infection(U = Urinary infection, R = Respiratory infection, B = Bloodstream, S = Surgical site infection, C = Cutaneous infection, E = Enteric infection, O = Other type of infection, No/Ex = No infection or extrahospitalary infection). Neg^∗ stands for any classification of InNoCBR different from a HAI: not acquired (indicated in parentheses), ignored, no infection or extrahospitalary infection.
