To the Editor: In their randomized controlled trial, Dr Timsit and colleagues1 concluded that use of a chlorhexidine gluconate–impregnated sponge (CHGIS) at the catheter insertion site may reduce catheter-related infections (CRIs). Moreover, extending the interval for dressing changes from 3 to 7 days had noninferior results. Because catheter insertion is applied to patients with severe injury or critical illness, physicians in intensive care units need to consider the effect of the injury or disease on selection of the insertion sites.
