Effectiveness of Chlorhexidine-Impregnated Central Venous Catheter Dressing for Preventing Catheter-Related Bloodstream Infections in Pediatric Patients: A Systematic Review and Meta-Analysis Study

Abstract

Objective The study's objective was to use meta-analysis to assess the effectiveness of a dressing impregnated with chlorhexidine in preventing catheter-related bloodstream infections (CRBSIs) in pediatric patients.

Methods The study was conducted and reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. A comprehensive search of 18 databases was conducted up to 5 March 2020 to identify related studies. Following the evaluation of the methodological quality, 8 studies, 1,584 catheters in 1,556 patients were added to the meta-analysis. The odds ratio and Hedge's G effect size value were employed to analyze the data. Either a fixed-effects model or a random-effects model was used to compute the effect size value with 95% confidence intervals (CIs). The heterogeneity of effect sizes was investigated using Cochrane Q statistics, I ², and Tau² tests. To test for publication bias, funnel plot, Orwin's safe n number, Begg and Mazumdar rank correlation, Egger test, and Duval and Tweedie's trim and fill procedures were all utilized.

Results The catheter colonization risk was lowered by 50.7% by the chlorhexidine-impregnated (C-I) dressing (odds ratio [OR] = 0.493 [%95 CI: 0.360–0.675]; p < 0.001). The use of C-I dressing was associated with a trend toward a decrease in CRBSIs, while this association was not statistically significant (OR = 0.858 [%95 CI: 0.567–1.300]; p = 0.471).

Conclusion The use of C-I dressing can effectively reduce the risk of catheter colonization, and it is also a helpful tactic in lowering CRBSIs in pediatric patients with central venous catheters, according to the findings of this meta-analysis.
