Augmenting the Activity of Chlorhexidine for Decolonization of Candida auris from Porcine skin

Candida auris readily colonizes skin and efficiently spreads among patients in healthcare settings worldwide. Given the capacity of this drug-resistant fungal pathogen to cause invasive disease with high mortality, hospitals frequently employ chlorhexidine bathing to reduce skin colonization. Using an ex vivo skin model, we show only a mild reduction in C. auris following chlorhexidine application. This finding helps explain why chlorhexidine bathing may have failures clinically, despite potent in vitro activity. We further show that isopropanol augments the activity of chlorhexidine against C. auris on skin. Additionally, we find both tea tree (Melaleuca alternifolia) oil and lemongrass (Cymbopogon flexuosus) oil to further enhance the activity of chlorhexidine/isopropanol for decolonization. We link this antifungal activity to individual oil components and show how some of these components act synergistically with chlorhexidine/isopropanol. Together, the studies provide strategies to improve C. auris skin decolonization through the incorporation of commonly used topical compounds.

Double-swab 5% versus single-swab 10% iodophor for reducing methicillin-resistant Staphylococcus aureus with routine chlorhexidine bathing

In a prospective cohort study, we compared a 2-swabs-per-nostril 5% iodophor regimen with a 1-swab-per-nostril 10% iodophor regimen on methicillin-resistant Staphylococcus aureus carriage in nursing-home residents. Compared with baseline, both single-swab and double-swab regimens resulted in an identical 40% reduction in nasal carriage and 60% reduction in any carriage, skin or nasal.

The Prevention of Periprosthetic Joint Infection in Primary Total Hip Arthroplasty Using Pre-Operative Chlorhexidine Bathing

Periprosthetic joint infection (PJI) after total hip arthroplasty (THA) is a devastating complication. The aim of this study was to investigate whether preoperative bathing using chlorhexidine gluconate (CHG) before THA can effectively reduce the postoperative PJI rate. A total of 933 primary THA patients, with the majority being female (54.4%) were included in the study. Primary THA patients who performed preoperative chlorhexidine bathing were assigned to the CHG group (190 subjects), and those who did not have preoperative chlorhexidine bathing were in the control group (743 subjects). The effects of chlorhexidine bathing on the prevention of PJI incidence rates were investigated. Differences in age, sex, and the operated side between the two groups were not statistically significant. Postoperative PJI occurred in four subjects, indicating an infection rate of 0.43% (4/933). All four infected subjects belonged to the control group. Although the PJI cases were significantly more in the control group than in the CHG group, statistical analysis revealed no statistical significance in the risk of PJI occurrence between the two groups (p = 0.588). Preoperative skin preparation by bathing with a 2% chlorhexidine gluconate cleanser did not produce significant effects on the prevention of postoperative PJI in primary THA.

Kata kunci: chlorhexidine gluconate, mandi chlorhexidine, infeksi terkait perawatan kesehatan ABSTRAKLatar Belakang: Infectious diseases in health facilities also known as Healthcare Associated Infections (HAIs) are major problem facing hospitals because they can increase morbidity rates (pain), mortality rates (deaths) and increase the cost of care for hospitals. Chlorhexidine gluconate as an antiseptic with broad spectrum antimicrobial activity is an important component in infection prevention. Daily bathing routine in critical or intensive care and pre-surgery showers with Chlorhexidine soap have reduced bloodstream infections, surgical area infections and the acquisition of harmful and resistant pathogenic organisms found in hospitals. However, due to the inconsistency of research results related to this matter, as a result chlorhexidine bathing has not been done universally as a permanent procedure and still leaves debate until now. This literature review aims to assess the effectiveness of chlorhexidine gluconate baths in reducing the incidence of infections related to health services and their causative microorganisms.

Strengthening Adherence to a Central-Line–Associated Bloodstream Infection Prevention Bundle in a Surgical ICU in Vietnam

Background: Central-line–associated bloodstream infections (CLABSIs) increase the length of hospital stay, healthcare costs, and patient mortality. Objective: We conducted a quality improvement (QI) approach with plan-do-study-act (PDSA) cycle to strengthen adherence to a central-line (CL) maintenance bundle and to reduce CLABSI rate in a surgical intensive care unit (ICU) of children’s hospital 1 (CH1). Methods: The baseline CLABSI rate per 1,000 CL days and the ratio of CL days to patient days (device utilization ration; DUR) were captured for 12 months preceding the intervention. Baseline process indicators were captured for 2 months preceding implementation, including hand hygiene adherence, sterile technique for dressing change and CL access, CL hub cleaning, dating of CL components and daily chlorhexidine bathing. A multimodal intervention of clinician training, bedside checklist, and poster reminders of best practices was implemented. Process and outcome measures were monitored over 12 months of implementation. Z-test was used to calculate statistical significance before and after intervention. Results: Among 46 clinical ICU staff trained on a CLABSI maintenance bundle, mean pre- and posttest knowledge scores increased from 63% to 86%. Staff adherence to each CL care bundle element improved significantly (P < .001) and sustainably over the intervention period: hand hygiene adherence increased from 54% to 82%; sterile technique for dressing increased from 60% to 94%; sterile technique for CL access increased from 51% to 97%; hub scrubbing increased from 52% to 93%; dating of CL elements increased from 63% to 85%; daily chlorhexidine bathing increased from 52% to 87%. During the first 9 months, the CLABSI rate and the DUR decreased from 5.8 to 3.7 and from 0.43 to 0.41, respectively. In the following 2 months, the CLABSI rate increased to 12.7 while bundle adherence remained high. A root-cause analysis identified inadequate environmental hygiene and use of multidose saline bottles for multiple patients as potential factors. A PDSA cycle to improve these elements (enhanced cleaning; single-patient saline bottles) led to a decrease in the CLABSI rate from 12.7 to 3.0 after these efforts. Conclusions: This is the first time CH1 has used quality improvement methodology to implement an HAI prevention enhancement, which proved effective at creating and sustaining adherence to a multimodal CL maintenance bundle and an overall decrease in CLABSI rates. A 2-month increase in CLABSI rates highlights the unique challenges faced in low-resource settings and demonstrates the need for IPC elements not captured in a typical CLABSI prevention bundle. The quality improvement methodology provided a structured approach to implementing change. This methodology will be used for additional patient safety improvements at CH1 and other Viet Nam hospitals interested in CLABSI prevention.Funding: NoneDisclosures: None

Assessing the Potential for Unintended Microbial Consequences of Routine Chlorhexidine Bathing for Prevention of Healthcare-associated Infections

Chlorhexidine gluconate (CHG) is an antiseptic that is widely used in healthcare due to its excellent safety profile and wide spectrum of activity. Daily bathing with CHG has proven to be effective in the prevention of healthcare-associated infections and multidrug-resistant pathogen decolonization. Despite the proven benefits of CHG use, there remain concerns and unanswered questions about the potential for unintended microbial consequences of routine CHG bathing. This review aims to explore some of these questions.
