  • CVC combines tunneled CVC and nontunneled CVC. Pooled mean rate = (total number of events/total number of patient-months) ×100. Percentiles are on the basis of the distribution of individual facility rates per 100 patient-months All rates are reported per 100 patient-months. CVC, central venous catheter.
