Implementation of a Clinical Protocol to Reduce Urinary Tract Infections Among Women With Urinary Retention After Pelvic Reconstructive Surgery: A Prospective Quality Improvement Study.

[OBJECTIVE] We implemented and assessed a clinical practice quality improvement protocol aimed at decreasing postoperative urinary tract infections (UTIs) among patients with transurethral catheters.

[METHODS] This was a quality improvement study with pre- and post-intervention comparisons. Patients requiring postoperative transurethral catheters underwent 3 interventions: (1) shortening the time from surgery to repeat voiding trials to 3-5 days for pelvic reconstructive surgeries and to 1-3 days for mid-urethral slings, (2) avoiding routine urine cultures at the time of voiding trials, and (3) recommending 2 L of water intake daily until 3 days after the voiding trial. The primary outcome was the percentage of patients receiving antibiotics for UTIs within 6 weeks. Secondary outcomes included rates of failing office voiding trials, UTI symptoms/cultures, adherence to hydration, and health care resource utilization.

[RESULTS] We included 31 patients before and 40 patients after the intervention. The 2 cohorts had similar demographic and clinical characteristics. Among patients requiring catheterization, rates of antibiotic treatment for UTIs decreased from 65% to 40% after the intervention (P = 0.04). UTI symptoms and urine cultures sent for analysis decreased significantly (P = 0.04 and P = 0.005, respectively). There was high adherence (84%) to increased hydration. Rates of failing office voiding trials remained similar. The number of phone calls decreased by 43% (P = 0.003), and there was no increase in office or emergency department visits. Multivariate regression showed that UTIs were 2.04 times more likely before than after the intervention.

[CONCLUSION] Our quality improvement intervention was practical to implement and effective in reducing postoperative UTIs among patients with urinary catheters.
