Use of an Antibacterial Powder Spray to Prevent Post Prostatectomy Urinary Infection

Effectiveness of meatal cleaning in the prevention of catheter-associated urinary tract infections and bacteriuria: an updated systematic review and meta-analysis

OBJECTIVE

A systematic review on meatal cleaning prior to urinary catheterisation and post catheterisation and reduces the risk catheter-associated urinary tract infections (CAUTIs) and bacteriuria was published in 2017, with further studies undertaken since this time. The objective of this paper is to present an updated systematic review on the effectiveness of antiseptic cleaning of the meatal area for the prevention of CAUTIs and bacteriuria in patients who receive a urinary catheter.

DESIGN

Systematic review.

DATA SOURCES

Electronic databases Cochrane Library, PubMed, Embase, The Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline and Academic Search Complete were searched from 1 January 2016 and 29 February 2020.

ELIGIBILITY CRITERIA

Randomised controlled trials (RCTs) and quasi-experimental studies evaluating the use of antiseptic, antibacterial or non-medicated agents for cleaning the meatal, periurethral or perineal areas before indwelling catheter insertion or intermittent catheterisation or during routine meatal care.

DATA EXTRACTION AND SYNTHESIS

Data were extracted using the Cochrane Collaboration's data collection form for RCTs and non-RCTs. Data were extracted by one researcher and then checked for accuracy by a second researcher.

RESULTS

A total of 18 studies were included. Some potential benefit of using antiseptics, compared with non-antiseptics for meatal cleaning to prevent bacteriuria and or CAUTI was identified (OR 0.84, 95% CI 0.69 to 1.02; p=0.071). Antiseptics (chlorhexidine or povidine-iodine) may be of value for meatal cleaning on the incidence of CAUTI, compared with comparator agents (saline, soap or antimicrobial cloths) (OR=0.65, 95% CI 0.42 to 0.99; p=0.047).

CONCLUSION

There is emerging evidence of the role of some specific antiseptics (chlorhexidine) prior to urinary catheterisation, in reducing CAUTIs, and some potential benefit to the role of antiseptics more generally in reducing bacteriuria.

Comparison of the preventive effect of urethral cleaning versus disinfection for catheter-associated urinary tract infections in adults: A network meta-analysis

BACKGROUND

Catheter-associated urinary tract infections (CAUTIs) are the main cause of infectious complications in patients with indwelling urinary catheters (IDCs). However, the best cleaning methods for the prevention of CAUTIs have not been evaluated clearly in previous studies.

METHODS

An electronic database search was performed, from inception to December 2017. Randomized controlled trials and quasi-experimental trials using different methods of urethral cleaning versus disinfection to prevent CAUTIs were considered. The study selection and data collection were performed independently by two reviewers. The risk of bias assessment was performed using the Cochrane risk of bias scale. The primary outcome was the incidence rates of CAUTIs. A network meta-analysis was conducted to compare the effect among the different methods of urethral cleaning versus disinfection to prevent CAUTIs.

RESULTS

Thirty-three studies (6490 patients) with seven different methods of urethral cleaning versus disinfection were eligible for inclusion, and the data were summarized in the network meta-analysis. No evidence of heterogeneity (P>0.05) was observed among the studies. The network meta-analysis showed that there was no difference in the incidence of CAUTIs when comparing the different urethral cleaning methods versus disinfection (P>0.05 for all). However, chlorhexidine ranked first in the results of the Bayesian analysis and is recommended for preventing CAUTIs.

CONCLUSIONS

Current evidence suggests that there are no significant differences among different urethral cleaning versus disinfection methods with regard to CAUTI incidence rates.
