AI summary — for doctors, generated from the abstract only

In a randomized controlled trial of ICU patients receiving continuous renal replacement therapy, antimicrobial glucose chlorhexidine catheter dressings resulted in a markedly lower local catheter insertion-site infection rate than sterile dressings.

What was studied

A prospective, randomized, single-blind trial at West China Hospital (September 2022-November 2023) randomized 410 ICU patients scheduled for CRRT vascular catheter placement to glucose chlorhexidine antimicrobial dressing (changed every 7 days) or sterile dressing (changed every 48 hours), comparing local infection rate, catheter-related bloodstream infections (CRBSIs), length of stay, and mortality.

Key findings

205 patients were randomized to each group (410 total) out of 520 screened.
Local infection rate at the catheter insertion site was 40.0% in the sterile dressing group versus 15.6% in the chlorhexidine dressing group, described by the authors as significantly greater in the sterile group; the exact p-value is truncated/garbled in the available abstract text (shown as 'p 0.05').
A Cox proportional hazards model indicated that patients in the control (sterile dressing) group had substantially greater risk of local infections and CRBSIs over time than the intervention group.
Not reported in the abstract (due to truncation): specific comparative figures for CRBSI incidence, length of hospital stay, ICU stay duration, and mortality are not given in the available abstract text.

Clinical relevance

The findings suggest that antimicrobial glucose chlorhexidine dressings may meaningfully reduce catheter insertion-site infections compared with standard sterile dressings in ICU patients on CRRT, which could support their use as an infection-prevention strategy. Because part of the abstract's statistical reporting is garbled, the significance of all secondary outcomes could not be fully confirmed from this text.

Limitations

Part of the abstract's results text is garbled/truncated, obscuring a precise p-value for the main infection outcome and omitting figures for several secondary outcomes; single-center design and single-blind (not double-blind) methodology may limit generalizability and introduce bias.

Antimicrobial glucose chlorhexidine dressings substantially reduced catheter insertion-site infections compared with sterile dressings in ICU patients on CRRT (40.0% vs 15.6%).

Abstract

Background

Catheter-related bloodstream infections (CRBSIs) are a major cause of complications in critically ill patients receiving continuous renal replacement therapy (CRRT), especially those with nontunneled catheters. These infections can lead to longer hospital stays, higher costs, and worse patient outcomes. Although sterile dressings are commonly used to prevent CRBSIs, antimicrobial dressings, such as those containing chlorhexidine, may offer better protection. This study aimed to compare the effectiveness of antimicrobial glucose chlorhexidine dressings and sterile dressings in preventing CRBSIs in patients receiving CRRT.

Methods

A prospective, randomized controlled, single-blind study was conducted. All participants were kept blinded to group assignment. We enrolled patients admitted to the Intensive Care Unit (ICU) of West China Hospital, Sichuan University between September 2022 and November 2023 who were scheduled for vascular catheter placement before receiving continuous renal replacement therapy (CRRT). The participants were randomly allocated to either the intervention group (receiving glucose chlorhexidine antimicrobial dressing) or the control group (receiving sterile dressing) via a random number table. The dressing was changed every 7 days for the glucose chlorhexidine antimicrobial group and every 48 h for the sterile dressing group, in accordance with the guideline. Dressings were replaced immediately if they became rolled, loose, or visibly soiled. The primary outcomes were the local infection rate at the catheter insertion site, suspected catheter-related bloodstream infections (CRBSIs), incidence of CRBSIs, length of hospital stay, ICU stay duration, and hospital mortality rates.

Results

A total of 520 patients were screened, and 410 patients were ultimately included in the study, with 205 patients in each group (glucose chlorhexidine antimicrobial dressing group and sterile dressing group). The incidence of local infection at the catheter insertion site was 40.0% in the sterile dressing group, which was significantly greater than the 15.6% reported in the glucose chlorhexidine antimicrobial dressing group (p 0.05). The Cox proportional hazards model suggested that patients in the control group were at a substantially greater risk of local infections and CRBSIs over time than those in the intervention group.

Conclusion

Glucose chlorhexidine antimicrobial dressings significantly reduce catheter insertion site infections and overall CRBSI incidence, demonstrating their clinical value in preventing infection in patients receiving CRRT.
