Value of Time to Positivity of Blood Culture in Children with Bloodstream Infections

Table 4

Predictive value of TTP of microorganisms from bloodstream infections.

Microorganisms	AUC	Cutoff (h)	Sensitivity (%)	Specificity (%)	PPV (%)	NPV (%)
CoNS+	0.928	22.72	88.57	93.33	93	89.09
S. aureus	0.874	19.6	66.67	100	100	75
K. pneumoniae	0.818	18.58	76.67	75	75.41	71.19
E. coli	0.792	16.43	80	83.33	92.30	80.64

TTP: time to positivity; CoNS: coagulase-negative Staphylococcus; AUC: area under the ROC curve; PPV: positive predictive value; NPV: negative predictive value.
