Does periurethral cleaning with water prior to indwelling urinary catheterization increase the risk of urinary tract infections? A systematic review and meta‐analysis
Abstract
Objective: To determine whether periurethral cleaning with water before indwelling urinary catheterization increases the risk of urinary tract infections (UTIs) compared with studies using anti‐infective agents. Methods: A literature search via MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials through October 2017 and a manual search of references for additional relevant studies. Trials studying clean intermittent catheterization were excluded. Data were extracted independently by 2 reviewers. Disagreements were resolved through discussion. Results of randomized controlled trials were pooled using random effects models. Both individual and pooled risk estimates were reported using risk ratios (RRs) and 95% confidence intervals (CIs). Results: From 121 identified articles, 5 studies involving 824 patients were included in the review (822 patients included in meta‐analysis). No statistical significance in the incidence of UTIs existed between the water group and antiseptics group (RR, 1.07; 95% CI, 0.77‐1.49; P = .89; I2 = 0%). Available data comparing water with povidone‐iodine or chlorhexidine gluconate demonstrated no significant difference between the incidence of UTIs (RR, 1.10; 95% CI, 0.66‐1.83; P = .79; I2 = 0%; and RR, 1.05; 95% CI, 0.68‐1.62; P = .72; I2 = 0%; respectively). Conclusions: Based on current data, water is as safe as other topical antiseptics for periurethral cleansing before indwelling urinary catheter insertion.
