Chlorhexidine gluconate transparent dressing does not decrease central line-associated bloodstream infection in critically ill patients: A randomized controlled trial.

ABSTRACT:

Background

Central line-associated blood stream infections are accompanied by increased mortality and health care costs. The application of different types of dressings in infection control has not been fully investigated to date.

Aim

To assess the effects of two different dressing types on central line-associated bloodstream infections.

Methods

A randomized, nonblinded, controlled trial was conducted. Central lines were randomly allocated to intervention (chlorhexidine gluconate transparent dressing, n = 259) and control groups (standard dressing, n = 215). The central line-associated bloodstream infection rate was assessed.

Results

A statistically nonsignificant difference was noted in the overall central line-associated bloodstream infection rates between the two groups. The frequency of dressing changes in the patients with the chlorhexidine gluconate transparent dressing was significantly lower than that in the patients with a standard dressing. The predominant type of infectious microorganisms isolated from the central line-associated bloodstream infection episodes was Gram-negative bacteria (57.2%). Gram-positive bacteria and fungi were noted at lower percentages (28.5% and 14.3%, respectively).

Conclusion

The use of a chlorhexidine gluconate transparent dressing does not decrease the central line-associated bloodstream infection rate, although it decreases the frequency of dressing changes so may save nursing time.

Project description:Chlorhexidine gluconate (CHG)-containing dressings are recommended to prevent central line associated bloodstream infections (CLABSIs) and other catheter-related infections. This study compared the effect of 2 CHG dressings on CLABSI, cost of care, and contact dermatitis. A retrospective analysis was conducted using the Premier Healthcare Database of hospitalized patients (n = 53 149) with central venous catheters (CVCs) and receiving either a transparent CHG gel dressing (n = 14 488) or an opaque CHG sponge dressing (n = 38 661) between January 2019 and September 2020. Two cohorts (n = 14 488 each), CHG-Gel and CHG-Sponge, were matched 1:1 using a propensity score method on 33 patient and facility characteristics. CLABSI and contact dermatitis rates, hospital length of stay (LOS), and hospitalization costs were compared using mixed-effect multiple regression. This approach effectively controlled for random clustering effects across hospitals and patients' Diagnosis-Related Group (DRG) classifications. CHG gel dressings were associated with a 41% decrease in CLABSI rates (P = .0008) compared to CHG sponge dressings (0.35%vs 0.60%). A 0.4-day shorter LOS (9.53vs 9.90 days, P = .0001) and a cost saving of $3576 per hospital stay ($40 197 vs $43 774, P = .0179) was observed with CHG gel dressing use. There was no statistically significant difference in contact dermatitis rates (P = .7854) between the CHG-Gel and CHG-Sponge cohorts. The findings of this study suggest that the use of CHG gel dressings may be more effective in reducing the risk of CLABSIs and associated clinical costs compared to CHG sponge dressings in hospitalized patients. Moreover, there appears to be no significant discrepancy in contact dermatitis rates between CHG gel and CHG sponge dressings. Healthcare providers may consider using CHG gel dressings as a standard practice for patients with CVCs to reduce the risk of infections and improve patient outcomes.

Project description:BackgroundCentral line-associated bloodstream infections (CLABSIs) result in approximately 28,000 deaths and approximately $2.3 billion in added costs to the U.S. healthcare system each year, and yet, many of these infections are preventable. At two large health systems in the southeast United States, CLABSIs continue to be an area of opportunity. Despite strong evidence for interventions to prevent CLABSI and reduce associated patient harm, such as use of chlorhexidine gluconate (CHG) bathing, the adoption of these interventions in practice is poor. The primary objective of this study was to assess the effect of a tailored, multifaceted implementation program on nursing staff's compliance with the CHG bathing process and electronic health record (EHR) documentation in critically ill patients. The secondary objectives were to examine the (1) moderating effect of unit characteristics and cultural context, (2) intervention effect on nursing staff's knowledge and perceptions of CHG bathing, and (3) intervention effect on CLABSI rates.MethodsA stepped wedged cluster-randomized design was used with units clustered into 4 sequences; each sequence consecutively began the intervention over the course of 4 months. The Grol and Wensing Model of Implementation helped guide selection of the implementation strategies, which included educational outreach visits and audit and feedback. Compliance with the appropriate CHG bathing process and daily CHG bathing documentation were assessed. Outcomes were assessed 12 months after the intervention to assess for sustainability.ResultsAmong the 14 clinical units participating, 8 were in a university hospital setting and 6 were in community hospital settings. CHG bathing process compliance and nursing staff's knowledge and perceptions of CHG bathing significantly improved after the intervention (p = .009, p = .002, and p = .01, respectively). CHG bathing documentation compliance and CLABSI rates did not significantly improve; however, there was a clinically significant 27.4% decrease in CLABSI rates.ConclusionsUsing educational outreach visits and audit and feedback implementation strategies can improve adoption of evidence-based CHG bathing practices.Trial registrationClinicalTrials.gov, NCT03898115 , Registered 28 March 2019.

Project description:BackgroundThe gut microbiome is believed to contribute to bloodstream infection (BSI) via translocation of dominant gut bacteria in vulnerable patient populations. However, conclusively linking gut and blood organisms requires stringent approaches to establish strain-level identity.MethodsWe enrolled a convenience cohort of critically ill patients and investigated 86 bloodstream infection episodes that occurred in 57 patients. Shotgun metagenomic sequencing was used to define constituents of their gut microbiomes, and whole genome sequencing and assembly was done on 23 unique bloodstream isolates that were available from 21 patients. Whole genome sequences were downloaded from public databases and used to establish sequence-identity distribution and define thresholds for unrelated genomes of BSI species. Gut microbiome reads were then aligned to whole genome sequences of the cognate bloodstream isolate and unrelated database isolates to assess identity.ResultsGut microbiome constituents matching the bloodstream infection species were present in half of BSI episodes, and represented >30% relative abundance of gut sequences in 10% of episodes. Among the 23 unique bloodstream organisms that were available for whole genome sequencing, 14 were present in gut at the species level. Sequence alignment applying defined thresholds for identity revealed that 6 met criteria for identical strains in blood and gut, but 8 did not. Sequence identity between BSI isolates and gut microbiome reads was more likely when the species was present at higher relative abundance in gut.ConclusionIn assessing potential gut source for BSI, stringent sequence-based approaches are essential to determine if organisms responsible for BSI are identical to those in gut: of 14 evaluable patients in which the same species was present in both sites, they were identical in 6/14, but were non-identical in 8/14 and thus inconsistent with gut source. This report demonstrates application of sequencing as a key tool to investigate infection tracking within patients.
