BACKGROUND: Duration of indwelling urinary catheterization is an important risk factor for urinary tract infection.

OBJECTIVES: To determine whether a reminder approach reduces the use of urinary catheters and the incidence of catheter-associated urinary tract infections.

METHODS: A randomized control trial was performed in 2 respiratory intensive care units in a 2990-bed tertiary referral medical center. Patients who had urinary catheters in place for more than 2 days from April through November 2008 were randomly assigned to either the intervention group (use of a criteria-based reminder to remove the catheter) or the control group (no reminder).

RESULTS: A total of 278 patients were recruited. Utilization rate of indwelling urinary catheters was decreased by 22% in the intervention group compared with the control group (relative risk, 0.78; 95% CI, 0.76-0.80; P < .001). The intervention significantly shortened the median duration of catheterization (7 days vs 11 days for the control group; P < .001). The success rate for removing the catheters in the intervention group by day 7 was 88%. The reminder intervention reduced the incidence of catheter-associated infections by 48% (relative risk, 0.52; 95% CI, 0.32-0.86; P = .009) in the intervention group compared with the control group.

CONCLUSIONS: Use of a criteria-based reminder to remove indwelling urinary catheters can diminish the use of urinary catheterization and reduce the likelihood of catheter-associated urinary infections. This reminder approach can prevent catheter-associated urinary infections, and its use should be strongly considered as a way to enhance the safety of patients.
