“…These catheters have been introduced into practice in the US and several studies support their efficacy, safety, and cost-effectiveness. [222324] However, the CAUTI-reducing effect observed in these studies varies considerably, suggesting that the efficacy is highly dependent on patient group characteristics, hospital and/or region, catheterization time period, and which definition of CAUTI has been used.…”

The efficacy of noble metal alloy urinary catheters in reducing catheter-associated urinary tract infection

Background:Catheter-associated urinary tract infection (CAUTI) is the most common device-related healthcare-acquired infection. CAUTI can be severe and lead to bacteremia, significant morbidity, prolonged hospital stay, and high antibiotic consumption.Patients and Methods:In this study, we evaluated the CAUTI-reducing efficacy of noble metal alloy catheters in sixty patients (thirty per group) in the Intensive Care Unit (ICU) at the King Fahad Hospital in Saudi Arabia. The study was a single-blinded, randomized, single-centered, prospective investigation that included patients using urinary catheters for 3 days.Results:A 90% relative risk reduction in the rate of CAUTI was observed with the noble metal alloy catheter compared to the standard catheter (10 vs. 1 cases, P = 0.006). When considering both catheter-associated asymptomatic bacteriuria and CAUTI, the relative risk reduction was 83% (12 vs. 2 cases, P = 0.005). In addition to CAUTI, the risk of acquiring secondary bacteremia was lower (100%) for the patients using noble metal alloy catheters (3 cases in the standard group vs. 0 case in the noble metal alloy catheter group, P = 0.24). No adverse events related to any of the used catheters were recorded.Conclusion:Results from this study revealed that noble metal alloy catheters are safe to use and significantly reduce CAUTI rate in ICU patients after 3 days of use.

“…This silver alloy hydrogel urinary catheter reduced 47% symptomatic CAUTI occurrences as defined by both NHSN and clinical criteria. Stenzelius et al compared the incidence of catheter‐associated bacteriuria with a silver‐coated catheter or a noncoated control catheter in patients undergoing elective orthopedic surgery with shorten catheterization . This study indicated that the silver alloy coating can significantly, up to 3.7‐fold, reduce the risk of catheter‐associated bacteriuria in short‐term catheterization (1–3 days).…”

Over 75% of hospital‐acquired or nosocomial urinary tract infections are initiated by urinary catheters, which are used during the treatment of 16% of hospitalized patients. Taking the United States as an example, the costs of catheter‐associated urinary tract infections (CAUTI) are in excess of $451 million dollars/year. The biofilm formation by pathogenic microbes that protects pathogens from host immune defense and antimicrobial agents is the leading cause for CAUTI. Thus, tremendous efforts have been devoted to antimicrobial coating for urinary catheters in the past few decades, and it has been demonstrated to be one of the most direct and efficient strategies to reduce infections. In this article, we briefly summarize the current methods for preparation of antimicrobial coatings based on different stages in the biofilm formation, highlight recent progress in the urinary catheter coating material design and selection, discuss approaches to improving their long‐term antimicrobial efficacy, biocompatibility, multidrug resistance and recurrent infections, and finally outline future requirements and prospects in antimicrobial coating material design. The scope of the works surveyed is confined to antimicrobial urinary catheters. © 2018 Wiley Periodicals, Inc. J Biomed Mater Res Part A: 107A: 445–467, 2019.

“…The addition of an extremely thin superficial layer (a few millionths of a millimetre) of a combination of the noble metals gold (Au), palladium (Pd) and silver (Au) [Bactiguard V R Infection Protection (BIP TM )] is claimed to reduce the bacterial adherence like other noble metals alloy are [13] and theoretically the subsequent frequency of symptomatic UTI. In a recent study of short-term perioperative and postoperative catheter treatment in patients undergoing elective joint replacement surgery, the frequency of UTI was significantly lower in patients receiving BIP-silicone catheters than in those with those managed with silicone-only catheters [14].…”
