Presentation and impact of catheter-associated thrombosis in patients with infected long-term central venous catheters: a prospective bicentric observational study

Bathing with wipes impregnated with chlorhexidine gluconate to prevent central line-associated bloodstream infection in critically ill patients: A systematic review with meta-analysis

BACKGROUND

Recommendations for different types of bathing to prevent central line-associated bloodstream infections (CLABSI) are still divergent. The objective of this study was to verify whether bed bathing with wipes impregnated with 2% chlorhexidine (CHG) compared to conventional bed bathing is more effective in preventing CLABSI.

METHODS

Systematic review of the literature by consulting the electronic databases PubMed/Medline, Embase, CINAHL, Scopus, and Web of Science from the date of inception until July 1, 2023, with no language or time restrictions.

RESULTS

A total of 84,462 studies were examined, of which 6 were included in the meta-analysis. Data from 20,188 critical care patients included in primary studies were analyzed. The meta-analysis found that bed bathing with wipes impregnated with 2% CHG reduced the risk of CLABSI by 48% compared to conventional bed bathing (risk ratio 0.52; 95% confidence interval, 0.37-0.73), and this is moderate-quality evidence. The reduction in length of stay in the intensive care unit and length of hospital stay as well as the risk of death were not significantly different between the study groups. Whether bed bathing with 2% CHG-impregnated wipes increases the occurrence of skin reactions is unclear.

CONCLUSIONS

This meta-analysis provides moderate-quality evidence that daily bathing with 2% CHG-impregnated wipes is safe and helps prevent CLABSI among adult intensive care unit patients.

Short-Course Versus Prolonged-Course Antimicrobial Therapy in Adults With Catheter-Related Septic Thrombosis: A Propensity-Weighted Retrospective Study

Background

Optimal duration of antimicrobial therapy (AT) for catheter-related septic deep venous thrombosis (DVT) is unknown. We aimed to compare the outcomes of patients receiving short-course AT (≤21 days) versus prolonged-course AT (>21 days).

Methods

This was a monocentric retrospective study comparing adults with catheter-related septic DVT from 2015 to 2020 treated with short- or prolonged-course AT. A propensity score-weighted analysis was used to mitigate potential bias. The primary outcome was a composite of all-cause mortality or recurrent bloodstream infection 30 days after AT discontinuation.

Results

Of 172 patients with catheter-related septic DVT, 104 were treated with prolonged-course AT and 68 with short-course AT. In the propensity score analysis, we found no significant difference in 30-day all-cause mortality or relapse between the 2 groups (inverse probability of treatment weighted hazard ratio [wHR], 2.16 [95% confidence interval {CI}, .68-6.88]; P = .192). No differences in 90-day all-cause mortality and 90-day relapse were observed between the treatment groups (wHR, 1.01 [95% CI, .49-2.05], P = .987 and 1.13 [95% CI, .08-15.62], P = .928, respectively).

Conclusions

A 21-day AT could be an effective and safe option to treat catheter-related septic DVT. Further randomized studies are needed to establish the optimal duration of AT for patients with catheter-related septic DVT.

Nurses' compliance with central line associated blood stream infection prevention guidelines

Objectives:

To assess nurses’ compliance with central line associated bloodstream infection (CLABSI) prevention guidelines related to maintenance of the central line and the predictors of compliance.

Method:

This was an observational study that used a descriptive cross-sectional design. A sample of 171 intensive care unit (ICU) nurses were observed and their compliance was recorded on a structured observational sheet. The study was conducted in the ICUs of 15 hospitals located in 5 cities in Jordan. Data were collected over a 5-month period from March to July 2017. Central lines were all inserted by physicians inside the ICUs.

Results:

One hundred and twenty participants (70%) showed sufficient compliance. The mean compliance scores were 14.2±4.7 (min=8, max=20); however, the rate of CLABSI was variable across the participating ICUs. Logistic regression with 4 independent variables (years of experience, previous education with CLABSI, nurse-patient ratio and the ICU’s bed capacity) was conducted to investigate predictors of sufficient compliance. The model was significant (χ²(4)=133.773, p=0.00). The nurse-patient ratio was the only significant predictor. Nurses with a 1:1 nurse:patient ratio demonstrated superior compliance over their counterparts with a 1:2 ratio.

Conclusion:

Further improvement in compliance and patients’ outcomes could be achieved by lowering the nurse-patient ratio.

Educating intensive care unit nurses to use central venous catheter infection prevention guidelines: effectiveness of an educational course

Background

Nurses' knowledge of central venous catheter-related infection (CVC-RI) prevention guidelines is poor, indicating that nurses do not receive proper education about these guidelines.

Aim

The aim of this study was to evaluate the effectiveness of an educational course that aimed to improve nurses' knowledge about CVC-RI prevention guidelines.

Method

A sample of 131 nurses were randomly assigned to the experimental group (received an educational course) or control group (received no education). Pre-Post data were collected using a structured questionnaire that included a 23-item knowledge assessment.

Results

In the pre-test, all participants demonstrated poor knowledge, with mean scores of 8.2 (standard deviation = 3.6). After completion of the course, knowledge was significantly improved in the experimental group, whereas the control group showed no change (t(106,3) = 25.1, p = 0.00).

Conclusions

An educational course on CVC-RI prevention guidelines had an encouraging effect. Decision makers are recommended to implement such courses in their settings to improve nurses' competency.
