Effect of a urine culture stewardship initiative on urine culture utilization and catheter-associated urinary tract infections in intensive care units.

Objective: Urine cultures have poor specificity for catheter-associated urinary tract infections (CAUTIs). We evaluated the effect of a urine-culture stewardship program on urine culture utilization and CAUTI in adult intensive care units (ICUs).

Design: A quasi-interventional study was performed from 2015 to 2017.
