Patient perceptions of chlorhexidine bathing: A pilot study using the health belief model

Descriptive epidemiology of central line-associated bloodstream infections at an academic medical center in Iowa, 2019-2022

BACKGROUND

Central line-associated bloodstream infections (CLABSIs) increased nationally during the COVID-19 pandemic. We described CLABSIs at our institution during 2019 to 2022.

METHODS

This retrospective observational study examined CLABSIs among adult inpatients at an 866-bed teaching hospital in the Midwest. CLABSI incidence was trended over time and compared to monthly COVID-19 admissions. Manual chart review was performed to obtain patient demographics, catheter-associated variables, pathogens, and clinical outcomes.

RESULTS

We identified 178 CLABSIs. The CLABSI incidence (cases per 1,000 line days) tripled in October 2020 as COVID-19 admissions increased. CLABSIs in 2020 were more frequently caused by coagulase-negative staphylococci and more frequently occurred in the intensive care units 7+ days after central line insertion. The CLABSI incidence normalized in early 2021 and did not increase during subsequent COVID-19 surges. Throughout 2019 to 2022, about half of the nontunneled central venous catheters involved in CLABSI were placed emergently. One-quarter of CLABSIs involved multiple central lines. Chlorhexidine skin treatment adherence was limited by patient refusal.

CONCLUSIONS

The increase in CLABSIs in late 2020 during a surge in COVID-19 admissions was likely related to central line maintenance but has resolved. Characterizing CLABSI cases can provide insight into adherence to guideline-recommended prevention practices and identify areas for improvement at individual institutions.

Emotional response of critically-ill cardiac patients during hygiene procedures in intensive care: a prospective and descriptive study

OBJECTIVE

to analyze the emotional response of critically-ill conscious patients during daily hygiene procedures in a Cardiology Intensive Care Unit and to compare it based on the existence of previous experiences or not.

METHOD

a prospective and descriptive study. A 30-item ad hoc survey based on the first-day hygiene procedures was applied to 148 patients. Questions are asked about the feelings during the hygiene procedures and about positive and negative aspects of the experience. The patients are compared based on whether they had been already subjected to hygiene procedures or not.

RESULTS

67.6% were men and their mean age was 67±15 years old; 45.9% proved to be satisfied, 27% felt embarrassment and 86.3% were grateful to the professionals for talking to them during the hygiene procedures. 33.1% of the patients had never been subjected to hygiene procedures in bed, were significantly younger and single, and presented a lower cleanliness sensation. 32% stated that they would like for a family member to collaborate in the hygiene procedures.

CONCLUSION

the patients do not feel that their intimacy is invaded when they are subjected to hygiene procedures and appreciate communication with the health personnel while this care is provided. Those who had never been subjected to hygiene procedures in bed are younger, feel more embarrassed and are more disturbed by interruptions, in addition to being more aware of them.

Reduction in patient refusal of CHG bathing

BACKGROUND

Daily chlorhexidine gluconate (CHG) bathing is a well-supported intervention to reduce patient's risk of central line associated bloodstream infection (CLABSI); however, compliance with this practice is suboptimal. One major barrier is patient refusals of CHG bathing. The purpose of this project was to implement tailored interventions to mitigate this barrier. The specific aims were to reduce patient refusals, increase compliance with CHG bathing, and evaluate CLABSI rates and nursing staff's knowledge of CHG bathing.

METHODS

Iterative Plan-Do-Study-Act (PDSA) cycles were implemented over the course of 6 months. Run charts were used to identify signals of improvement. Interventions included printed educational flyers for staff and patients, educational sessions, an electronic learning module, and a "badge buddy."

RESULTS

We saw a reduction in the median percentage of patient refusals documented, from 23% to 8% after the PDSA cycles. Documentation compliance with CHG bathing increased only slightly from 46% to 47%. CLABSI rates decreased 6% from 0.69 to 0.65.

DISCUSSION

Using interventions tailored to the clinical setting can impact patient outcomes. Other health care systems should consider implementing PDSA cycles to improve evidence-based practices.

CONCLUSIONS

Using PDSA cycles can result in a reduction in patient refusal documentation, and may slightly improve CHG bathing compliance and CLABSI rates.

A Quality Improvement Project to Decrease CLABSIs in Non-ICU Settings

BACKGROUND AND OBJECTIVES

Central line-associated bloodstream infections (CLABSIs) are a common, preventable healthcare-associated infection. In our 3-hospital health system, CLABSI rates in non-intensive care unit (ICU) settings were above the internal target rate of zero. A robust quality improvement (QI) project to reduce non-ICU CLABSIs was undertaken by a team of Doctor of Nursing Practice (DNP)-prepared nurse leaders enrolled in a post-DNP Quality Implementation Scholars program and 2 QI experts. Based on a review of the literature and local root cause analyses, the QI team implemented the evidence-based practice of using 2% chlorhexidine gluconate (CHG) cloths for daily bathing for non-ICU patients with a central line.

METHODS

A pre-post-design was used for this QI study. CHG bathing was implemented using multifaceted educational strategies that included an e-learning module, printed educational materials, educational outreach, engagement of unit-based CLABSI champions, and an electronic reminder in the electronic health record. Generalized linear mixed-effects models were used to assess the change in CLABSI rates before and after implementation of CHG bathing. CLABSI rates were also tracked using statistical process control (SPC) charts to monitor stability over time. CHG bathing documentation compliance was audited as a process measure. These audit data were provided to unit-based leadership (nurse managers and clinical team leaders) on a monthly basis. A Qualtrics survey was also disseminated to nursing leadership to evaluate their satisfaction with the CHG bathing implementation processes.

RESULTS

Thirty-four non-ICU settings participated in the QI study, including general medical/surgical units and specialty areas (oncology, neurosciences, cardiac, orthopedic, and pediatrics). While the change in CLABSI rates after the intervention was not statistically significant ( b = -0.35, P = .15), there was a clinically significant CLABSI rate reduction of 22.8%. Monitoring the SPC charts demonstrated that CLABSI rates remained stable after the intervention at all 3 hospitals as well as the health system. CHG bathing documentation compliance increased system-wide from 77% (January 2020) to 94% (February 2021). Overall, nurse leaders were satisfied with the CHG bathing implementation process.

CONCLUSIONS

To sustain this practice change in non-ICU settings, booster sessions will be completed at least on an annual basis. This study provides further support for using CHG cloths for daily patient bathing in the non-ICU setting.

Horizontal approaches to infection prevention: daily chlorhexidine gluconate bathing

Healthcare-associated infections (HAIs) pose a significant challenge in hospitals. Infection control strategies have been widely employed to mitigate their incidence. In hospitals, chlorhexidine gluconate (CHG) solutions are commonly used as antiseptic skin cleansers as part of comprehensive infection prevention bundles, with daily CHG bathing being highly effective in reducing HAIs and lowering skin micro-organism density. This evidence review addresses the challenges of risk stratification in implementing CHG bathing protocols in hospitals. It highlights the benefits of a horizontal approach, where CHG bathing is implemented across the entire facility rather than being limited to specific patient populations. Evidence from systematic reviews and studies suggests that CHG bathing consistently reduces HAI rates in both intensive care unit (ICU) and non-ICU settings, supporting the adoption of a hospital-wide approach. The findings emphasise the significance of incorporating CHG bathing as part of a comprehensive approach to infection prevention in hospitals and highlight the potential for cost savings.

Program Evaluation of Implementation Science Outcomes From an Intervention to Improve Compliance With Chlorhexidine Gluconate Bathing: A Qualitative Study

BACKGROUND AND OBJECTIVES

Evaluation of implementation science research is warranted to better understand and determine the success of translating evidence-based infection prevention practices at the bedside. The purpose of this program evaluation was to evaluate implementation outcomes from the perspectives of nurses and nursing leaders regarding a previously conducted chlorhexidine gluconate (CHG) bathing implementation science study among 14 critical care units.

METHODS

Focus groups and interviews, using semistructured interview questions, were conducted to examine the perceptions of nurses who participated in a CHG bathing implementation science study. A deductive qualitative analysis using Proctor and colleagues' implementation outcomes framework was used. Transcripts were analyzed and categorized using the framework as a predetermined code list to structure the implementation outcomes of acceptability, appropriateness, adoption, feasibility, and sustainability.

FINDINGS

A total of 19 nurses and nurse leaders participated in a focus group or interview. Participants noted that both implementation strategies used in the initial study (educational outreach and audit and feedback) were acceptable and appropriate and expressed that the evidence-based CHG bathing practice was feasible to integrate into practice and was being adopted.

DISCUSSION

The program evaluation identified strengths and opportunities for improvement related to the implementation strategies and evidence-based CHG bathing protocol. Findings can inform future studies that seek to implement CHG bathing protocols in the critical care setting using audit and feedback and educational outreach strategies.

Implementing daily chlorhexidine gluconate (CHG) bathing in VA settings: The human factors engineering to prevent resistant organisms (HERO) project

BACKGROUND

Daily use of chlorhexidine gluconate (CHG) has been shown to reduce risk of healthcare-associated infections. We aimed to assess moving CHG bathing into routine practice using a human factors approach. We evaluated implementation in non-intensive care unit (ICU) settings in the Veterans Health Administration.

METHODS

Our multiple case study approach included non-ICU units from 4 Veterans Health Administration settings. Guided by the Systems Engineering Initiative for Patient Safety, we conducted focus groups and interviews to capture barriers and facilitators to daily CHG bathing. We measured compliance using observations and skin CHG concentrations.

RESULTS

Barriers to daily CHG include time, concern of increasing antibiotic resistance, workflow and product concerns. Facilitators include engagement of champions and unit shared responsibility. We found shortfalls in patient education, hand hygiene and CHG use on tubes and drains. CHG skin concentration levels were highest among patients from spinal cord injury units. These units applied antiseptic using 2% CHG impregnated wipes vs 4% CHG solution/soap.

DISCUSSION

Non-ICUs implementing CHG bathing must consider human factors and work system barriers to ensure uptake and sustained practice change.

CONCLUSIONS

Well-planned rollouts and a unit culture promoting shared responsibility are key to compliance with daily CHG bathing. Successful implementation requires attention to staff education and measurement of compliance.

Chlorhexidine Gluconate Bathing Reduces the Incidence of Bloodstream Infections in Adults Undergoing Inpatient Hematopoietic Cell Transplantation

Bloodstream infections (BSIs) occur in 20% to 45% of inpatient autologous and allogeneic hematopoietic cell transplant (HCT) patients. Daily bathing with the antiseptic chlorhexidine gluconate (CHG) has been shown to reduce the incidence of BSIs in critically ill patients, although very few studies include HCT patients or have evaluated the impact of compliance on effectiveness. We conducted a prospective cohort study with historical controls to assess the impact of CHG bathing on the rate of BSIs and gut microbiota composition among adults undergoing inpatient HCT at the Duke University Medical Center. We present 1 year of data without CHG bathing (2016) and 2 years of data when CHG was used on the HCT unit (2017 and 2018). Because not all patients adhered to CHG, patients were grouped into four categories by rate of daily CHG usage: high (>75%), medium (50% to 75%), low (1% to 49%), and none (0%). Among 192 patients, univariate trend analysis demonstrated that increased CHG usage was associated with decreased incidence of clinically significant BSI, defined as any BSI requiring treatment by the medical team (high, 8% BSI; medium, 15.2%; low, 15.6%; no CHG, 30.3%; P = .003), laboratory-confirmed BSI (LCBI; P = .03), central line-associated BSI (P = .04), and mucosal barrier injury LCBI (MBI-LCBI; P = .002). Multivariate analysis confirmed a significant effect of CHG bathing on clinically significant BSI (P = .023) and MBI-LCBI (P = .007), without consistently impacting gut microbial diversity. Benefits of CHG bathing were most pronounced with >75% daily usage, and there were no adverse effects attributable to CHG. Adherence to daily CHG bathing significantly decreases the rate of bloodstream infection following HCT.
