Davies PE, et al. - Researchers performed a comparison of rates of urinary catheterization and catheter-associated urinary tract infections (CAUTIs) before and after the implementation of a bundled intervention. They observed that optimization of culturing practices was essential to prevent the CAUTI rate from increasing from a reduced denominator despite a decrease observed in the number of patients exposed to urinary catheters and catheter days. To improve patient safety and hospital performance, implementation of a CAUTI prevention bundle worked synergistically.
