Risk of nosocomial infection scale = 6 x ≤1 year old c) + (7x malnutrition ≥ II c) + (27 x PRISM ≥ 10 c) + (10 x CVP c) + (8 x intubation c) + (17 x bladder catheter c) + (10 x parenteral nutrition c) (c = 1 if risk factor appears; c=0 if not), the risk of nosocomial infection is high with sensitivity of 86, 4% and specificity of 81, 2% if scale is more than 32.
