Boyce JM. Best products for skin antisepsis. Am J Infect Control 2023; 51:A58-A63. [PMID: 37890954 DOI: 10.1016/j.ajic.2023.02.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Accepted: 02/05/2023] [Indexed: 10/29/2023]
Abstract
BACKGROUND Skin antiseptics are used for several purposes before surgical procedures, for bathing high-risk patients as a means of reducing central line-associated infections and other health care associated infections. METHODS A PubMed search was performed to update the evidence on skin antiseptic products and practices. RESULTS Current guidelines for prevention of surgical site infections (SSIs) recommend preoperative baths or showers with a plain or antimicrobial soap prior to surgery, but do not make recommendations on the timing of baths, the total number of baths needed, or about the use of chlorhexidine gluconate (CGH)-impregnated cloths. Randomized controlled trials have demonstrated that pre-operative surgical hand antisepsis using an antimicrobial soap or alcohol-based hand rub yields similar SSI rates. Other studies have reported that using an alcohol-based hand rub caused less skin irritation, was easier to use, and required shorter scrub times than using antimicrobial soap. Current SSI prevention guidelines recommend using an alcohol-containing antiseptic for surgical site infection. Commonly used products contain isopropanol combined with either CHG or with povidone-iodine. Surgical site preparation protocols for shoulder surgery in men may need to include coverage for anaerobes. Several studies suggest the need to monitor and improve surgical site preparation techniques. Daily bathing of intensive care unit (ICU) patients with a CHG-containing soap reduces the incidence of central line-associated bloodstream infections (CLABSIs). Evidence for a similar effect in non-ICU patients is mixed. Despite widespread CHG bathing of ICU patients, numerous barriers to its effective implementation exist. Measuring CHG levels on the skin is useful for identifying gaps in coverage and suboptimal skin concentrations. Using alcohol-based products with at least 2% CHG for skin preparation prior to central line insertion reduces CLABSIs. CONCLUSIONS Progress has been made on skin antisepsis products and protocols, but improvements in technique are still needed.

Implementing daily chlorhexidine gluconate (CHG) bathing in VA settings: The human factors engineering to prevent resistant organisms (HERO) project. Am J Infect Control 2021; 49:775-783. [PMID: 33359552 DOI: 10.1016/j.ajic.2020.12.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2020] [Revised: 12/12/2020] [Accepted: 12/21/2020] [Indexed: 10/22/2022]
Abstract
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. Transplant Cell Ther 2021; 27:262.e1-262.e11. [PMID: 33781532 DOI: 10.1016/j.jtct.2021.01.004] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Revised: 12/09/2020] [Accepted: 01/03/2021] [Indexed: 11/20/2022]
Abstract
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.

Abstract
Staphylococcus aureus infections are associated with increased morbidity, mortality, hospital stay, and health care costs. S aureus colonization has been shown to increase risk for invasive and noninvasive infections. Decolonization of S aureus has been evaluated in multiple patient settings as a possible strategy to decrease the risk of S aureus transmission and infection. In this article, we review the recent literature on S aureus decolonization in surgical patients, patients with recurrent skin and soft tissue infections, critically ill patients, hospitalized non-critically ill patients, dialysis patients, and nursing home residents to inform clinical practice.

Abstract
Background Children undergoing hematopoietic stem cell transplantation (HSCT) are at high risk for hospital-associated bloodstream infections (HA-BSIs). This study aimed to describe the incidence, microbiology, and risk factors for HA-BSI in pediatric HSCT recipients. Methods We performed a single-center retrospective cohort study of children and adolescents (<18 years of age) who underwent HSCT over a 20-year period (1997–2016). We determined the incidence and case fatality rate of HA-BSI by causative organism. We used multivariable Poisson regression to identify risk factors for HA-BSI. Results Of 1294 patients, the majority (86%) received an allogeneic HSCT, most commonly with umbilical cord blood (63%). During the initial HSCT hospitalization, 334 HA-BSIs occurred among 261 (20%) patients. These were classified as gram-positive bacterial (46%), gram-negative bacterial (24%), fungal (12%), mycobacterial (<1%), or polymicrobial (19%). During the study period, there was a decline in the cumulative incidence of HA-BSI (P = .021) and, specifically, fungal HA-BSIs (P = .002). In multivariable analyses, older age (incidence rate ratio [IRR], 1.03; 95% confidence interval [CI], 1.01–1.06), umbilical cord blood donor source (vs bone marrow; IRR, 1.69; 95% CI, 1.19–2.40), and nonmyeloablative conditioning (vs myeloablative; IRR, 1.85; 95% CI, 1.21–2.82) were associated with a higher risk of HA-BSIs. The case fatality rate was higher for fungal HA-BSI than other HA-BSI categories (21% vs 6%; P = .002). Conclusions Over the past 2 decades, the incidence of HA-BSIs has declined among pediatric HSCT recipients at our institution. Older age, umbilical cord blood donor source, and nonmyeloablative conditioning regimens are independent risk factors for HA-BSI among children undergoing HSCT.

Wiemken TL. Skin antiseptics in healthcare facilities: is a targeted approach necessary? BMC Public Health 2019; 19:1158. [PMID: 31438910 PMCID: PMC6705093 DOI: 10.1186/s12889-019-7507-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2019] [Accepted: 08/15/2019] [Indexed: 12/01/2022] Open
Abstract
Background Skin antisepsis occurs in every healthcare environment. From basic hand hygiene, to antiseptic bathing and pre surgical care with alcohol/chlorhexidine, use of antimicrobial agents to reduce the skin microflora has skyrocketed in the past several years. Although used in hopes of reducing the likelihood of infection in patients, many products have been identified as the source of infection in several outbreaks, sometimes due to the nonsterile nature of the many readily available antiseptics. Body Intrinsic contamination of antiseptics during the manufacturing process is common. In fact, since the majority of these products are sold as nonsterile, they are allowed some level of microbial contamination based on the United States Pharmacopeia documents 61 and 62. Unfortunately, sometimes this contamination is with microorganisms resistant to the antiseptic and/or with those pathogenic to humans. In this scenario, healthcare-associated infections may occur, leaving the patient at higher risk of mortality and increasing costs of care substantially. Although antibiotic stewardship programs throughout the world suggest targeting use of antibiotics to limit resistance, few healthcare environments include other antimicrobial agents (such as antiseptics) in their programs. Conclusion Due to the potential for contamination with pathogenic organisms and the increased likelihood of selecting for resistant organisms with widespread use of broad-spectrum agents with non-specific mechanisms of action, a discussion around including skin antiseptics in stewardship programs is necessary, particularly those labeled as nonsterile. At minimum, debating the pros and cons of targeting use of daily antiseptic bathing in hospitalized patients should occur. Through mindfully incorporating any antimicrobial agent, sterile or not, into our repertoire of anti-infectives, we can save patient lives, reduce infection, and save costs.

Abstract
Application of antiseptic products to the skin plays an important role in prevention of a variety of health care-associated infections. Preoperative bathing or showering is widely recommended to reduce the risk of surgical site infections. Evidence of the impact of this measure on surgical site infection rates is mixed, and further prospective trials comparing standardized protocols for showering with plain soap or chlorhexidine gluconate (CHG)-containing soap, or bathing with 2% CHG-impregnated cloths are needed to establish the most effective approach. Current evidence favors the use of alcohol-containing solutions, often containing CHG or povidone-iodine, for surgical site preparation of the skin. Preparation of vaginal mucosa prior to gynecologic surgery may be performed using either povidone-iodine or CHG. Surgical hand antisepsis can be performed by scrubbing with an antimicrobial soap or by handrubbing using an alcohol-based handrub. Addition of CHG to alcohol-based handrubs intended for surgical hand antisepsis is not necessary if they meet recommended efficacy criteria. Daily CHG bathing of intensive care unit patients has been shown to reduce a variety of health care-associated infections, most commonly bloodstream infections (BSIs). Achieving and maintaining optimum application protocols may be challenging, suggesting the need for ongoing staff education, monitoring, and feedback. Additional studies are needed to determine the impact of daily CHG bathing of non-intensive care unit patients. Alcoholic CHG is currently the preferred antiseptic for skin preparation prior to insertion of central and arterial intravascular catheters. CHG-impregnated dressings have been shown to reduce catheter-associated BSI. Because of the widespread use of antiseptics, especially CHG, surveillance for emergence of increased tolerance or resistance is warranted. Antiseptics are applied to the skin for a variety of purposes in health care. Common scenarios in which topical antiseptics are used include preoperative bathing, surgical site preparation, surgical hand hygiene, daily bathing of intensive care unit patients, and prevention of intravascular catheter-associated BSI. The purpose of this article is to review recent evidence regarding the best products for skin antisepsis.

Abstract
Background Chlorhexidine gluconate (CHG) bathing of hospitalized patients may have benefit in reducing hospital-acquired bloodstream infections (HABSIs). However, the magnitude of effect, implementation fidelity, and patient-centered outcomes are unclear. In this meta-analysis, we examined the effect of CHG bathing on prevention of HABSIs and assessed fidelity to implementation of this behavioral intervention. Methods We undertook a meta-analysis by searching Medline, EMBASE, CINAHL, Scopus, and Cochrane’s CENTRAL registry from database inception through January 4, 2019 without language restrictions. We included randomized controlled trials, cluster randomized trials and quasi-experimental studies that evaluated the effect of CHG bathing versus a non-CHG comparator for prevention of HABSIs in any adult healthcare setting. Studies of pediatric patients, of pre-surgical CHG use, or without a non-CHG comparison arm were excluded. Outcomes of this study were HABSIs, patient-centered outcomes, such as patient comfort during the bath, and implementation fidelity assessed through five elements: adherence, exposure or dose, quality of the delivery, participant responsiveness, and program differentiation. Three authors independently extracted data and assessed study quality; a random-effects model was used. Results We included 26 studies with 861,546 patient-days and 5259 HABSIs. CHG bathing markedly reduced the risk of HABSIs (IRR = 0.59, 95% confidence interval [CI]: 0.52–0.68). The effect of CHG bathing was consistent within subgroups: randomized (0.67, 95% CI: 0.53–0.85) vs. non-randomized studies (0.54, 95% CI: 0.44–0.65), bundled (0.66, 95% CI: 0.62–0.70) vs. non-bundled interventions (0.51, 95% CI: 0.39–0.68), CHG impregnated wipes (0.63, 95% CI: 0.55–0.73) vs. CHG solution (0.41, 95% CI: 0.26–0.64), and intensive care unit (ICU) (0.58, 95% CI: 0.49–0.68) vs. non-ICU settings (0.56, 95% CI: 0.38–0.83). Only three studies reported all five measures of fidelity, and ten studies did not report any patient-centered outcomes. Conclusions Patient bathing with CHG significantly reduced the incidence of HABSIs in both ICU and non-ICU settings. Many studies did not report fidelity to the intervention or patient-centered outcomes. For sustainability and replicability essential for effective implementation, fidelity assessment that goes beyond whether a patient received an intervention or not should be standard practice particularly for complex behavioral interventions such as CHG bathing.

Lancet 2019; 393:1205-1215. [PMID: 30850112 PMCID: PMC6650266 DOI: 10.1016/s0140-6736(18)32593-5] [Citation(s) in RCA: 71] [Impact Index Per Article: 14.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2018] [Revised: 08/28/2018] [Accepted: 10/11/2018] [Indexed: 01/09/2023]
Abstract
BACKGROUND Universal skin and nasal decolonisation reduces multidrug-resistant pathogens and bloodstream infections in intensive care units. The effect of universal decolonisation on pathogens and infections in non-critical-care units is unknown. The aim of the ABATE Infection trial was to evaluate the use of chlorhexidine bathing in non-critical-care units, with an intervention similar to one that was found to reduce multidrug-resistant organisms and bacteraemia in intensive care units. METHODS The ABATE Infection (active bathing to eliminate infection) trial was a cluster-randomised trial of 53 hospitals comparing routine bathing to decolonisation with universal chlorhexidine and targeted nasal mupirocin in non-critical-care units. The trial was done in hospitals affiliated with HCA Healthcare and consisted of a 12-month baseline period from March 1, 2013, to Feb 28, 2014, a 2-month phase-in period from April 1, 2014, to May 31, 2014, and a 21-month intervention period from June 1, 2014, to Feb 29, 2016. Hospitals were randomised and their participating non-critical-care units assigned to either routine care or daily chlorhexidine bathing for all patients plus mupirocin for known methicillin-resistant Staphylococcus aureus (MRSA) carriers. The primary outcome was MRSA or vancomycin-resistant enterococcus clinical cultures attributed to participating units, measured in the unadjusted, intention-to-treat population as the HR for the intervention period versus the baseline period in the decolonisation group versus the HR in the routine care group. Proportional hazards models assessed differences in outcome reductions across groups, accounting for clustering within hospitals. This trial is registered with ClinicalTrials.gov, number NCT02063867. FINDINGS There were 189 081 patients in the baseline period and 339 902 patients (156 889 patients in the routine care group and 183 013 patients in the decolonisation group) in the intervention period across 194 non-critical-care units in 53 hospitals. For the primary outcome of unit-attributable MRSA-positive or VRE-positive clinical cultures (figure 2), the HR for the intervention period versus the baseline period was 0·79 (0·73-0·87) in the decolonisation group versus 0·87 (95% CI 0·79-0·95) in the routine care group. No difference was seen in the relative HRs (p=0·17). There were 25 (<1%) adverse events, all involving chlorhexidine, among 183 013 patients in units assigned to chlorhexidine, and none were reported for mupirocin. INTERPRETATION Decolonisation with universal chlorhexidine bathing and targeted mupirocin for MRSA carriers did not significantly reduce multidrug-resistant organisms in non-critical-care patients.

Abstract
BACKGROUND Many studies investigating daily chlorhexidine gluconate (CHG) bathing as an infection control intervention to decrease health care-associated infections have focused on reduction of infection and colonization; few studies have assessed CHG bathing compliance, work system factors, facilitators, and barriers to implementation. METHODS This is a combination retrospective/prospective pilot study conducted at a large academic teaching hospital that implemented daily CHG bathing across all inpatient units. CHG compliance and patient refusal were calculated on the basis of documentation in the electronic medical record. We used the health belief model to guide semistructured interviews with patients about knowledge and barriers related to CHG bathing. RESULTS Of the 31 patients interviewed, 74% reported using CHG soap during their stay. Average compliance documented in the electronic medical record was 78% with a range of 57%-91% among all hospital units. Sixteen percent of patients declined CHG bathing, and refusal ranged from 3%-29% among all units. Major themes about CHG bathing from patient interviews include low perceived susceptibility to infection, high degree of trust in medical professionals, low knowledge of benefits of CHG, and low perceived self-efficacy in preventing HAIs. CONCLUSIONS Educating patients about CHG bathing appears to be a critical factor in decreasing patient refusal of CHG bathing.

Cheah ALY, Cheng AC, Spelman D, Nation RL, Kong DCM, McBryde ES. Mathematical modelling of vancomycin-resistant enterococci transmission during passive surveillance and active surveillance with contact isolation highlights the need to identify and address the source of acquisition. BMC Infect Dis 2018; 18:511. [PMID: 30309313 PMCID: PMC6182842 DOI: 10.1186/s12879-018-3388-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2017] [Accepted: 09/17/2018] [Indexed: 01/14/2023] Open
Abstract
Background Clinical studies and mathematical simulation suggest that active surveillance with contact isolation is associated with reduced vancomycin-resistant enterococci (VRE) prevalence compared to passive surveillance. Models using pre- and post-intervention data that account for the imperfect observation and serial dependence of VRE transmission events can better estimate the effectiveness of active surveillance and subsequent contact isolation; however, such analyses have not been performed. Methods A mathematical model was fitted to surveillance data collected pre- and post-implementation of active surveillance with contact isolation in the haematology-oncology ward. We developed a Hidden Markov Model to describe undetected and observed VRE colonisation/infection status based on the detection activities in the ward. Bayesian inference was used to estimate transmission rates. The effectiveness of active surveillance was assumed to be via increased detection and subsequent contact isolation of VRE positive patients. Results We estimated that 31% (95% credible interval: 0.33–85%) of the VRE transmissions were due to cross-transmission between patients. The ratio of transmission rates from patients with contact isolation versus those without contact isolation was 0.33 (95% credible interval: 0.050–1.22). Conclusions The majority of the VRE acquisitions in the haematology-oncology ward was estimated to be due to background rates of VRE, rather than within ward patient to patient acquisition. The credible interval for cross-transmission was wide which results in a large degree of uncertainty in the estimates. Factors that could account for background VRE acquisition include endogenous acquisition from antibiotic selection pressure and VRE in the environment. Contact isolation was not significantly associated with reduced VRE transmission in settings where the majority of VRE acquisition was due to background acquisition, emphasising the need to identify and address the source of acquisition. As the credible interval for the ratio of VRE transmission in contact isolated versus non-contact isolated patients crossed 1, there is a probability that the transmission rate in contact isolation was not lower. Our finding highlights the need to optimise infection control measures other than active surveillance for VRE and subsequent contact isolation to reduce VRE transmission. Such measures could include antimicrobial stewardship, environmental cleaning, and hand hygiene.

Abstract
Background The effects of chlorhexidine-based body washing (CHW) on health care-associated infections have been reported in numerous studies, while their findings remain conflicting. This study aims to update the evidence for the effects of CHW on the risk of colonization or infection with hospital-acquired methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE). Methods Two independent authors searched PubMed, Embase, and Cochrane Library from inception through February 2018. We selected all observational studies or clinical trials for the effect of CHW on the risk of colonization and infection with hospital-acquired MRSA or VRE. Random-effects models were applied to calculate summary incidence rate ratios (IRRs) for the related associations. Results Of 140 records identified, we obtained data from 17 relevant articles for meta-analysis. Compared with patients without antiseptic bathing, patients with CHW had a significantly lower risk of MRSA colonization (IRR 0.61, 95% CI 0.48–0.77) and VRE colonization (IRR 0.58, 95% CI 0.42–0.80). Similarly, we also noted that patients with CHW had a significantly lower risk of MRSA infection (IRR 0.65, 95% CI 0.52–0.81). However, no significantly lower risk of VRE infection (IRR 0.61, 95% CI 0.30–1.25) was noted in patients with CHW. Sensitivity analyses or trim-and-fill method confirmed the robustness of the findings. Conclusion Current evidence supports that patients with CHW had a significantly lower risk of MRSA or VRE colonization and a lower risk of MRSA infection. More evidence should be accumulated to reinforce these findings, especially on the effect of CHW on the risk of VRE infection.

Abstract
OBJECTIVE Prevention of Clostridium difficile infection (CDI) in acute-care hospitals is a priority for hospitals and clinicians. We performed a qualitative systematic review to update the evidence on interventions to prevent CDI published since 2009. DESIGN We searched Ovid, MEDLINE, EMBASE, The Cochrane Library, CINAHL, the ISI Web of Knowledge, and grey literature databases from January 1, 2009 to August 1, 2015. SETTING We included studies performed in acute-care hospitals. PATIENTS OR PARTICIPANTS We included studies conducted on hospitalized patients that investigated the impact of specific interventions on CDI rates. INTERVENTIONS We used the QI-Minimum Quality Criteria Set (QI-MQCS) to assess the quality of included studies. Interventions were grouped thematically: environmental disinfection, antimicrobial stewardship, hand hygiene, chlorhexidine bathing, probiotics, bundled approaches, and others. A meta-analysis was performed when possible. RESULTS Of 3,236 articles screened, 261 met the criteria for full-text review and 46 studies were ultimately included. The average quality rating was 82% according to the QI-MQCS. The most effective interventions, resulting in a 45% to 85% reduction in CDI, included daily to twice daily disinfection of high-touch surfaces (including bed rails) and terminal cleaning of patient rooms with chlorine-based products. Bundled interventions and antimicrobial stewardship showed promise for reducing CDI rates. Chlorhexidine bathing and intensified hand-hygiene practices were not effective for reducing CDI rates. CONCLUSIONS Daily and terminal cleaning of patient rooms using chlorine-based products were most effective in reducing CDI rates in hospitals. Further studies are needed to identify the components of bundled interventions that reduce CDI rates. Infect Control Hosp Epidemiol 2017;38:476-482.

The objective of this study was to determine understanding of bed bathing practices over time after the implementation of a standardized bed bathing protocol. An online survey addressing bathing practices was administered preintervention and 6 and 18 months postintervention to all nurses and technicians caring for adult patients. Survey responses suggested that the intervention resulted in sustained understanding of the standardized bed bathing protocol.

Abstract
Enterococcus faecium is one of the primary causes of nosocomial infections. Disinfectants are commonly used to prevent infections with multidrug-resistant E. faecium in hospitals. Worryingly, E. faecium strains that exhibit tolerance to disinfectants have already been described. We aimed to identify and characterize E. faecium genes that contribute to tolerance to the disinfectant chlorhexidine (CHX). We used a transposon mutant library, constructed in a multidrug-resistant E. faecium bloodstream isolate, to perform a genome-wide screen to identify genetic determinants involved in tolerance to CHX. We identified a putative two-component system (2CS), composed of a putative sensor histidine kinase (ChtS) and a cognate DNA-binding response regulator (ChtR), which contributed to CHX tolerance in E. faecium Targeted chtR and chtS deletion mutants exhibited compromised growth in the presence of CHX. Growth of the chtR and chtS mutants was also affected in the presence of the antibiotic bacitracin. The CHX- and bacitracin-tolerant phenotype of E. faecium E1162 was linked to a unique, nonsynonymous single nucleotide polymorphism in chtR Transmission electron microscopy showed that upon challenge with CHX, the ΔchtR and ΔchtS mutants failed to divide properly and formed long chains. Normal growth and cell morphology were restored when the mutations were complemented in trans Morphological abnormalities were also observed upon exposure of the ΔchtR and ΔchtS mutants to bacitracin. The tolerance to both chlorhexidine and bacitracin provided by ChtRS in E. faecium highlights the overlap between responses to disinfectants and antibiotics and the potential for the development of cross-tolerance for these classes of antimicrobials.

Reduction in hospital-associated methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus with daily chlorhexidine gluconate bathing for medical inpatients. Am J Infect Control 2017; 45:255-259. [PMID: 27938986 DOI: 10.1016/j.ajic.2016.09.019] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2016] [Revised: 09/03/2016] [Accepted: 09/06/2016] [Indexed: 11/21/2022]
Abstract
BACKGROUND Daily bathing with chlorhexidine gluconate (CHG) is increasingly used in intensive care units to prevent hospital-associated infections, but limited evidence exists for noncritical care settings. METHODS A prospective crossover study was conducted on 4 medical inpatient units in an urban, academic Canadian hospital from May 1, 2014-August 10, 2015. Intervention units used CHG over a 7-month period, including a 1-month wash-in phase, while control units used nonmedicated soap and water bathing. Rates of hospital-associated methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) colonization or infection were the primary end point. Hospital-associated S. aureus were investigated for CHG resistance with a qacA/B and smr polymerase chain reaction (PCR) and agar dilution. RESULTS Compliance with daily CHG bathing was 58%. Hospital-associated MRSA and VRE was decreased by 55% (5.1 vs 11.4 cases per 10,000 inpatient days, P = .04) and 36% (23.2 vs 36.0 cases per 10,000 inpatient days, P = .03), respectively, compared with control cohorts. There was no significant difference in rates of hospital-associated Clostridium difficile. Chlorhexidine resistance testing identified 1 isolate with an elevated minimum inhibitory concentration (8 µg/mL), but it was PCR negative. CONCLUSIONS This prospective pragmatic study to assess daily bathing for CHG on inpatient medical units was effective in reducing hospital-associated MRSA and VRE. A critical component of CHG bathing on medical units is sustained and appropriate application, which can be a challenge to accurately assess and needs to be considered before systematic implementation.

Abstract
BACKGROUND Daily bathing with chlorhexidine gluconate (CHG) of intensive care unit (ICU) patients has been shown to reduce healthcare-associated infections and colonization by multidrug resistant organisms. The objective of this project was to describe the process of daily CHG bathing and identify the barriers and facilitators that can influence its successful adoption and sustainability in an ICU of a Veterans Administration Hospital. METHODS We conducted 26 semi-structured interviews with a convenience sample of 4 nurse managers (NMs), 13 registered nurses (RNs) and 9 health care technicians (HCTs) working in the ICU. We used qualitative content analysis to code and analyze the data. Dedoose software was used to facilitate data management and coding. Trustworthiness and scientific integrity of the data were ensured by having two authors corroborate the coding process, conducting member checks and keeping an audit trail of all the decisions made. RESULTS Duration of the interviews was 15 to 39 min (average = 26 min). Five steps of bathing were identified: 1) decision to give a bath; 2) ability to give a bath; 3) decision about which soap to use; 4) delegation of a bath; and 5) getting assistance to do a bath. The bathing process resulted in one of the following three outcomes: 1) complete bath; 2) interrupted bath; and 3) bath not done. The outcome was influenced by a combination of barriers and facilitators at each step. Most barriers were related to perceived workload, patient factors, and scheduling. Facilitators were mainly organizational factors such as the policy of daily CHG bathing, the consistent supply of CHG soap, and support such as reminders to conduct CHG baths by nurse managers. CONCLUSIONS Patient bathing in ICUs is a complex process that can be hindered and interrupted by numerous factors. The decision to use CHG soap for bathing was only one of 5 steps of bathing and was largely influenced by scheduling/workload and patient factors such as clinical stability, hypersensitivity to CHG, patient refusal, presence of IV lines and general hygiene. Interventions that address the organizational, provider, and patient barriers to bathing could improve adherence to a daily CHG bathing protocol.

Abstract
OBJECTIVE To determine the effectiveness of daily bathing with 2% chlorhexidine-impregnated washcloths in preventing multidrug-resistant (MDR) gram-positive bacterial colonization and bloodstream infection. METHODS A randomized, open-label controlled trial was conducted in 4 medical intensive care units (ICUs) in Thailand from December 2013 to January 2015. Patients were randomized to receive cleansing with non-antimicrobial soap (control group) or 2% chlorhexidine-impregnated washcloths used to wipe the patient's body once daily (chlorhexidine group). Swabs were taken from nares, axilla, antecubital, groin, and perianal areas on admission and on day 3, 5, 7, and 14. The 5 outcomes were (1) favorable events ( all samples negative throughout ICU admission, or initially positive samples with subsequent negative samples); (2) MDR bacteria colonization-free time; (3) hospital-acquired infection; (4) length of ICU and hospital stay; (5) adverse skin reactions. RESULTS A total of 481 patients were randomly assigned to the control group (241) or the chlorhexidine group (240). Favorable events at day 14 were observed in 34.8% of patients in the control group and 28.6% in the chlorhexidine group (P=.79). Median MDR bacteria colonization-free times were 5 days in both groups. The incidence rate of hospital-acquired infection and the length of the ICU and hospital stay did not differ significantly between groups. The incidence of adverse skin reactions in the chlorhexidine group was 2.5%. CONCLUSION The effectiveness of 2% chlorhexidine-impregnated washcloths for the prevention of MDR gram-negative bacteria colonization and hospital-acquired infection in adult patients in ICU was not proven.

Abstract
BACKGROUND/AIMS Healthcare-associated infections (HAIs) in critically ill patients with prolonged length of hospital stay and increased medical costs. The aim of this study is to assess whether daily chlorhexidine gluconate (CHG) bathing will significantly reduce the rates of HAIs in adult intensive care units (ICUs). METHODS PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials were systematically searched until December 31, 2014 to identify relevant studies. Two authors independently reviewed and extracted data from included studies. All data was analyzed by Review Manager version 5.3. RESULTS Fifteen studies including three randomized controlled trials and 12 quasi-experimental studies were available in this study. The outcomes showed that daily CHG bathing were associated with significant reduction in the rates of primary outcomes: catheter-related bloodstream infection (risk ratio [RR], 0.44; 95% confidence interval [CI], 0.32 to 0.63; p < 0.00001), catheter-associated urinary tract infection (RR, 0.68; 95% CI, 0.52 to 0.88; p = 0.004), ventilator-associated pneumonia (RR, 0.73; 95% CI, 0.57 to 0.93; p = 0.01), acquisition of methicillin-resistant Staphylococcus aureus (RR, 0.78; 95% CI, 0.68 to 0.91; p = 0.001) and vancomycin-resistant Enterococcus (RR, 0.56; 95% CI, 0.31 to 0.99; p = 0.05). CONCLUSIONS Our study suggests that the use of daily CHG bathing can significantly prevent HAIs in ICUs. However, more well-designed studies are needed to confirm these findings.

Abstract
Vancomycin-resistant enterococci (VRE) infections have acquired prominence as a leading cause of health care-associated infections. Understanding VRE epidemiology, transmission modes in health care settings, risk factors for colonization, and infection is essential to prevention and control of VRE infections. Infection control strategies are pivotal in management of VRE infections and should be based on patient characteristics, hospital needs, and available resources. Hand hygiene is basic to decrease acquisition of VRE. The effectiveness of surveillance and contact precautions is variable and controversial in endemic settings, but important during VRE outbreak investigations and control. Environmental cleaning, chlorhexidine bathing, and antimicrobial stewardship are vital in VRE prevention and control.

Abstract
BACKGROUND Health-care-associated infections (HAIs), infections that patients contract during the course of their hospitalization, are receiving a growing amount of attention. Heavy skin bacterial colonization aids in the transmission and development of HAIs. Nurses frequently use bathing with chlorhexidine gluconate (CHG) to reduce patients' cutaneous microbial burden. This intervention has been shown to have promising but mixed results in the prevention of HAIs. PURPOSE This article reviews the literature for evidence on the impact of CHG bathing on HAIs. METHOD A literature search was conducted to identify peer-reviewed studies and meta-analyses that examined the impact of CHG bathing on HAIs using PubMed and CINAHL with the following search terms: CHG bathing AND healthcare associated infections, surgical site infections ( SSIs), central line associated bloodstream infections ( CLABSIs), ventilator-associated pneumonias ( VAP), catheter-associated urinary-tract infections ( CAUTIs), and Clostridium difficile-associated disease. The initial search identified 23 articles for review. Additional studies were identified by searching references used in original studies or review articles on this topic. PRINCIPLE FINDINGS There is good evidence to support incorporating a CHG bathing regimen to reduce the incidence of CLABSIs, SSIs, vancomycin-resistant enterococci (VRE), and methicillin-resistant Staphylococcus aureus (MRSA) HAIs. CONCLUSION As CHG becomes a standard practice to prevent HAIs, it is important to monitor for adverse reactions and evidence of resistance/susceptibility.

Abstract
We undertook a systems engineering approach to evaluate housewide implementation of daily chlorhexidine bathing. We performed direct observations of the bathing process and conducted provider and patient surveys. The main outcome was compliance with bathing using a checklist. Fifty-seven percent of baths had full compliance with the chlorhexidine bathing protocol. Additional time was the main barrier. Institutions undertaking daily chlorhexidine bathing should perform a rigorous assessment of implementation to optimize the benefits of this intervention.

Abstract
BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) is a virulent organism causing substantial morbidity and mortality in intensive care units. Chlorhexidine gluconate, a topical antiseptic solution, is effective against a wide spectrum of gram-positive and gram-negative bacteria, including MRSA. Objectives To examine the impact of a bathing protocol using chlorhexidine gluconate and bath basin management on MRSA acquisition in 5 adult intensive care units and to examine the cost differences between chlorhexidine bathing by using the bath-basin method versus using prepackaged chlorhexidine-impregnated washcloths. METHODS The protocol used a 4-oz bottle of 4% chlorhexidine gluconate soap in a bath basin of warm water. Patients in 3 intensive care units underwent active surveillance for MRSA acquisition; patients in 2 other units were monitored for a new positive culture for MRSA at any site 48 hours after admission. RESULTS Before the protocol, 132 patients acquired MRSA in 34333 patient days (rate ratio, 3.84). Afterwards, 109 patients acquired MRSA in 41376 patient days (rate ratio, 2.63). The rate ratio difference is 1.46 (95% CI, 1.12-1.90; P = .003). The chlorhexidine soap and bath basin method cost $3.18 as compared with $5.52 for chlorhexidine-impregnated wipes (74% higher). CONCLUSIONS The chlorhexidine bathing protocol is easy to implement, cost-effective, and led to decreased unit-acquired MRSA rates in a variety of adult intensive care units.

Abstract
OBJECTIVE To assess an intervention to limit community-associated methicillin-resistant Staphylococcus aureus (MRSA) dissemination. DESIGN Randomized, controlled trial. SETTING County Jail, Dallas, Texas. PARTICIPANTS A total of 4,196 detainees in 68 detention tanks. METHODS Tanks were randomly assigned to 1 of 3 groups: in group 1, detainees received cloths that contained chlorhexidine gluconate (CHG) to clean their entire skin surface 3 times per week for 6 months; group 2 received identical cloths containing only water; and group 3 received no skin treatment. During the study, all newly arrived detainees were invited to enroll. Nares and hand cultures were obtained at baseline and from all current enrollees at 2 and 6 months. RESULTS At baseline, S. aureus was isolated from 41.2% and MRSA from 8.0% (nares and/or hand) of 947 enrollees. The average participation rate was 47%. At 6 months, MRSA carriage was 10.0% in group 3 and 8.7% in group 1 tanks (estimated absolute risk reduction [95% confidence interval (CI)], 1.4% [-4.8% to 7.1%]; P = .655). At 6 months, carriage of any S. aureus was 51.1% in group 3, 40.7% in group 1 (absolute risk reduction [95% CI], 10.4% [0.01%-20.1%]; P = .047), and 42.8% (absolute risk reduction [95% CI], 8.3% [-1.4% to 18.0%]; P = .099) in group 2. CONCLUSIONS Skin cleaning with CHG for 6 months in detainees, compared with no intervention, significantly decreased carriage of S. aureus, and use of water cloths produced a nonsignificant but similar decrease. A nonsignificant decrease in MRSA carriage was found with CHG cloth use. TRIAL REGISTRATION ClinicalTrials.gov identifier NCT00785200.

Abstract
IMPORTANCE Daily bathing of critically ill patients with the broad-spectrum, topical antimicrobial agent chlorhexidine is widely performed and may reduce health care-associated infections. OBJECTIVE To determine if daily bathing of critically ill patients with chlorhexidine decreases the incidence of health care-associated infections. DESIGN, SETTING, AND PARTICIPANTS A pragmatic cluster randomized, crossover study of 9340 patients admitted to 5 adult intensive care units of a tertiary medical center in Nashville, Tennessee, from July 2012 through July 2013. INTERVENTIONS Units performed once-daily bathing of all patients with disposable cloths impregnated with 2% chlorhexidine or nonantimicrobial cloths as a control. Bathing treatments were performed for a 10-week period followed by a 2-week washout period during which patients were bathed with nonantimicrobial disposable cloths, before crossover to the alternate bathing treatment for 10 weeks. Each unit crossed over between bathing assignments 3 times during the study. MAIN OUTCOMES AND MEASURES The primary prespecified outcome was a composite of central line-associated bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTIs), ventilator-associated pneumonia (VAP), and Clostridium difficile infections. Secondary outcomes included rates of clinical cultures that tested positive for multidrug-resistant organisms, blood culture contamination, health care-associated bloodstream infections, and rates of the primary outcome by ICU. RESULTS During the chlorhexidine bathing period, 55 infections occurred: 4 CLABSI, 21 CAUTI, 17 VAP, and 13 C difficile. During the control bathing period, 60 infections occurred: 4 CLABSI, 32 CAUTI, 8 VAP, and 16 C difficile. The primary outcome rate was 2.86 per 1000 patient-days during the chlorhexidine and 2.90 per 1000 patient-days during the control bathing periods (rate difference, -0.04; 95% CI, -1.10 to 1.01; P = .95). After adjusting for baseline variables, no difference between groups in the rate of the primary outcome was detected. Chlorhexidine bathing did not change rates of infection-related secondary outcomes including hospital-acquired bloodstream infections, blood culture contamination, or clinical cultures yielding multidrug-resistant organisms. In a prespecified subgroup analysis, no difference in the primary outcome was detected in any individual intensive care unit. CONCLUSION AND RELEVANCE In this pragmatic trial, daily bathing with chlorhexidine did not reduce the incidence of health care-associated infections including CLABSIs, CAUTIs, VAP, or C difficile. These findings do not support daily bathing of critically ill patients with chlorhexidine. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT02033187.

Abstract
Although originally described in Staphylococcus aureus, resistance among bacteria has now become a race to determine which classes of bacteria will become more resistant. Availability of antibacterial agents has allowed the development of entirely new diseases caused by nonbacterial pathogens, related largely to fungi that are inherently resistant to antibacterials. This article presents the growing body of knowledge of the herpes family of viruses, and their occurrence and consequences in patients with concomitant surgical disease or critical illness. The focus is on previously immunocompetent patients, as the impact of herpes viruses in immunosuppressed patients has received thorough coverage elsewhere.

Abstract
OBJECTIVE Exposure of healthcare personnel to bloodborne pathogens (BBPs) can be prevented in part by using safety-engineered sharp devices (SESDs) and other safe practices, such as double gloving. In some instances, however, safer devices and practices cannot be utilized because of procedural factors or the lack of a manufactured safety device for the specific clinical use. In these situations, a standardized system to examine requests for waiver from expected practices is necessary. DESIGN Before-after program analysis. SETTING Large academic medical center. INTERVENTIONS Vanderbilt University Medical Center developed a formalized system for an improved waiver process, including an online submission and tracking site, and standards surrounding implementation of core safe practices. The program's impact on sharp device injuries and utilization of double gloving and blunt sutures was examined. RESULTS Following implementation of the enhanced program, there was an increase in the amount of undergloves and blunt sutures purchased for surgical procedures, suggesting larger utilization of these practices. The rate of sharp device injuries of all at-risk employees decreased from 2.32% to 2.12%, but this decline was not statistically significant (P = .14). The proportion of reported injuries that were deemed preventable significantly decreased from 72.7% (386/531) before implementation to 63.9% (334/523; P = .002) after implementation of the enhanced program. CONCLUSIONS An enhanced BBP protection program was successful at providing guidance to increase safe practices and at improving the management of SESD waiver requests and was associated with a reduction in preventable sharp device injuries.

Abstract
OBJECTIVE To control nosocomial transmission of methicillin-resistant Staphylococcus aureus (MRSA) in resource-limited healthcare setting with high endemicity. METHODS Three phases of infection control interventions were implemented in a University-affiliated hospital between 1-January-2004 and 31-December-2012. The first phase of baseline period, defined as the first 48-months of the study period, when all MRSA patients were managed with standard precautions, followed by a second phase of 24-months, when a hospital-wide hand hygiene campaign was launched. In the third phase of 36-months, contact precautions in open cubicle, use of dedicated medical items, and 2% chlorhexidine gluconate daily bathing for MRSA-positive patients were implemented while hand hygiene campaign was continued. The changes in the incidence rates of hospital-acquired MRSA-per-1000-patient admissions, per-1000-patient-days, and per-1000-MRSA-positive-days were analyzed using segmented Poisson regression (an interrupted time series model). Usage density of broad-spectrum antibiotics was monitored. RESULTS During the study period, 4256 MRSA-positive patients were newly diagnosed, of which 1589 (37.3%) were hospital-acquired. The reduction of hospital-acquired MRSA per 1000-patient admissions, per 1000-patient-days, and per 1000-MRSA-positive-days from phase 1 to 2 was 36.3% (p<0.001), 30.4% (p<0.001), and 19.6% (p = 0.040), while the reduction of hospital-acquired MRSA per 1000-patient admissions, per 1000-patient-days, and per 1000-MRSA-positive-days from phase 2 to 3 was 27.4% (p<0.001), 24.1% (p<0.001), and 21.9% (p = 0.041) respectively. This reduction is sustained despite that the usage density of broad-spectrum antibiotics has increased from 132.02 (phase 1) to 168.99 per 1000 patient-days (phase 3). CONCLUSIONS Nosocomial transmission of MRSA can be reduced with hand hygiene campaign, contact precautions in open cubicle, and 2% chlorhexidine gluconate daily bathing for MRSA-positive despite an increasing consumption of broad-spectrum antibiotics.

Abstract
BACKGROUND Vancomycin-resistant Enterococcus (VRE) screening is routine practice in many intensive care units despite the question of its clinical significance. The value of VRE screening at predicting subsequent VRE or other hospital-acquired infection (HAI) is unknown. The purpose of this investigation was to examine the rate of subsequent VRE HAI in patients undergoing VRE screening. METHODS This study was conducted in a 24-bed surgical intensive care unit (SICU) at a Level I trauma center. Patients admitted to the SICU between February and August 2011 who had rectal swab for VRE screening within 72 hours were followed prospectively for the development of VRE and other HAIs. Demographics, clinical characteristics, and infection rates were compared between VRE-positive and VRE-negative patients. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of VRE screening for predicting subsequent VRE HAI were calculated. RESULTS A total of 341 patients had VRE screening within 72 hours of SICU admission, with 32 VRE-positive (9%) and 309 VRE-negative (91%) patients. VRE-positive patients had a higher incidence of any HAI (78% vs. 35%, p < 0.001). Eight VRE-positive patients (25%) developed VRE HAI compared with only 3 VRE-negative patients (1%) (p < 0.001). VRE screening had a 73% sensitivity, 93% specificity, 25% PPV, and 99% NPV for determining subsequent VRE HAI. CONCLUSION VRE colonization was present in 9% of SICU patients at admission. Negative VRE screen result had a high specificity and NPV for the development of subsequent VRE HAI. Empiric treatment of VRE infection may be unnecessary in VRE-negative patients. LEVEL OF EVIDENCE Prognostic/epidemiologic study, level III. Therapeutic study, level IV.

Abstract
Children with immunocompromising conditions represent a unique group for the acquisition of antimicrobial resistant infections due to their frequent encounters with the health care system, need for empiric antimicrobials, and immune dysfunction. These infections are further complicated in that there is a relative paucity of literature on the clinical features and management of Staphylococcus aureus infections in immunocompromised children. The available literature on the clinical features, antimicrobial susceptibility, and management of S. aureus infections in immunocompromised children is reviewed. S. aureus infections in children with human immunodeficiency virus (HIV) are associated with higher HIV viral loads and a greater degree of CD4 T-cell suppression. In addition, staphylococcal infections in children with HIV often exhibit a multidrug resistant phenotype. Children with cancer have a high rate of S. aureus bacteremia and associated complications. Increased tolerance to antiseptics among staphylococcal isolates from pediatric oncology patients is an emerging area of research. The incidence of S. aureus infections among pediatric solid organ transplant recipients varies considerably by the organ transplanted; in general however, staphylococci figure prominently among infections in the early posttransplant period. Staphylococcal infections are also prominent pathogens among children with a number of immunodeficiencies, notably chronic granulomatous disease. Significant gaps in knowledge exist regarding the epidemiology and management of S. aureus infection in these vulnerable children.

Abstract
Chlorhexidine gluconate (CHG) decreases hospital-acquired methicillin-resistant Staphylococcus aureus (MRSA) that can cause colonization and infection. A standard approach is the bathing of all patients with CHG to prevent MRSA transmission. To decrease CHG utilization, this study assessed selective daily administration of CHG bathing to intensive care unit patients who had an MRSA-positive result or a central venous catheter. This risk-based approach was associated with a 72% decrease in hospital-acquired MRSA transmission rate.

Abstract
OBJECTIVE Chlorhexidine gluconate (CHG) is a common and safe antimicrobial agent and has been used widely in hand hygiene and skin disinfection; however, whether daily bathing with CHG results in the reduced acquired infection of methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) remains inconclusive. METHODS We did a meta-analysis searching PubMed, Embase and the Cochrane Central Register database for available studies. Primary outcomes were acquired infection of MRSA, VRE. RESULTS In all, twelve articles were available in this review. We found that daily application of chlorhexidine bathing would significantly low the acquired colonization of MRSA [incidence rate ratio (IRR) =0.58, 95% confidence interval (CI): 0.41-0.82] or VRE (IRR =0.51, 95% CI: 0.36-0.73). Remarkably, the using of CHG bathing would significantly reduce the MRSA infection (IRR =0.56, 95% CI: 0.37-0.85), MRSA ventilator associated pneumonia (VAP) (IRR =0.22, 95% CI: 0.07-0.64) and VRE infection (IRR =0.57, 95% CI: 0.33-0.97). No significant publication bias was found in this meta-analysis. CONCLUSIONS The application of CHG bathing would significantly decrease acquired infection of MRSA or VRE, which may be an important complementary intervention to barrier precautions.

Abstract
BACKGROUND Use of chlorhexidine gluconate wipes and pre-packed washcloths has been described for preventing pathogen spread in healthcare settings. AIM To assess the impact of chlorhexidine washcloths/wipes in preventing the spread of pathogens. METHODS Extensive and structured literature search from studies in Google Academic, Cochrane Library, Web of Science, Pubmed and Cinahl from their inception until November 2012. FINDINGS Final analysis included 15 studies, 9 of which were randomised controlled trials. The most frequent setting was the intensive care unit. In intensive care units, a significant reduction of bloodstream infection was associated with intervention and 3 studies revealed a decrease in blood culture contamination. One study showed a decrease in staff and environmental contamination and no increase in chlorhexidine resistance with intervention. Positive blood cultures for multiple pathogens also declined with intervention. In a paediatric intensive care unit, intervention decreased bacteraemia and catheter-associated bloodstream infection. In hospital wards, intervention was associated to a 64% reduction of pathogen transmission. One study had no statistically significant results. Pre-surgical chlorhexidine use significantly decreased bacterial colonisation but had no impact on surgical site infections. Regarding maternal and perinatal setting, one study did not show reduction of early onset neonatal sepsis and pathogen transmission. Another study of vaginal and neonatal decolonisation with chlorhexidine wiping revealed significant reduction in colonisation. One study concluded that single and multiple umbilical cord cleansing reduced the likelihood for a positive swab in 25% and 29%, respectively. Neonatal wiping maintained low levels of skin colonisation for a 24h period, for multiple pathogens. CONCLUSION Current evidence supports the usefulness of chlorhexidine washcloths and wipes in an intensive care, hospital and pre-surgical setting. More studies are required to encourage its use for prevention of perinatal and neonatal transmission of pathogens.

Abstract
BACKGROUND Daily skin cleansing with washcloths impregnated with chlorhexidine gluconate (CHG) of patients in intensive care unit is associated with reduction in incidence of vancomycin-resistant Enterococci (VRE) acquisition. This study describes the impact on incidence of VRE colonization after the implementation of daily skin cleansing with 2% CHG-impregnated washcloths in hematology-oncology patients. METHODS In this before-and-after study, we compared the incidence rate of VRE colonization during the baseline period (where routine soap-and-water bathing was used) with the intervention period where patients were cleansed with 2% CHG-impregnated washcloths. RESULTS Acquisition of VRE decreased from 7.8% in the baseline to 3.8% in the intervention period (relative risk, 0.48, 95% confidence interval [CI], 0.21-1.09; P = .07). The crude relative rate of acquisition during the intervention period compared with the baseline period was 0.53 (95% CI, 0.23-1.23; P = .13). Patients who had been a roommate of a patient subsequently found to have VRE were at a significantly increased risk for acquiring VRE (hazard ratio, 18.8, 95% CI, 5.37-66.15; P < .001). However, patients admitted to the same bed number of previously known VRE-colonized patient were not at increased risk of VRE acquisition (hazard ratio, 0.37, 95% CI, 0.11-1.22; P = .10). CONCLUSION We did not observe a statistically significant reduction in the rate of VRE colonization in association with the use of 2% CHG-impregnated washcloths among hematology-oncology patients.

Abstract
BACKGROUND : Patients with malignancies represent a population at high risk for drug-resistant infections. We sought to determine the clinical spectrum and molecular epidemiology of Staphylococcus aureus infections in pediatric oncology patients followed at Texas Children's Hospital (Houston, TX). Furthermore, we determined the prevalence of the chlorhexidine resistance gene qacA/B from isolates in this unique population. METHODS : Patients with a history of malignancy and a culture-proven S. aureus infection were identified from 2001 to 2011. Antibiotic susceptibility, pulsed-field gel electrophoresis and detection of qacA/B by polymerase chain reaction were performed on all isolates. Medical records for all patients were reviewed. RESULTS : During the study period, 213 isolates were identified from 179 patients with malignancies. Thirty-one percent of the isolates were methicillin-resistant S. aureus. The most common infectious diagnosis was bacteremia (85/213 [39.9%], with 72/85 [84.7%] being catheter-associated). Thirteen patients with bacteremia were found to have pulmonary nodules at the time of presentation; only S. aureus was found in tissue in 5 of the 6 patients who underwent lung biopsy. After 2007, 18.2% of isolates were qacA/B positive with a steady increase in prevalence every year (χ for trend P = 0.04). CONCLUSIONS : S. aureus is a significant cause of morbidity and mortality in pediatric oncology patients at Texas Children's Hospital. In addition to the more well-known clinical manifestations, this pathogen can also be associated with pulmonary nodules. Furthermore, the prevalence of S. aureus isolates carrying antiseptic resistance genes increased in this population. Additional clinical and molecular studies and surveillance among pediatric oncology patients are warranted to further explore these findings.

Abstract
AIM This paper describes a structured approach for documenting a search strategy, prior to the scholarly critique and review of the retrieved literature. BACKGROUND AND CONTEXT There has been a shift in publication expectations when it comes to the presentation of a literature review, from the more traditional narrative review to a more systematic approach, following a specific framework. METHODS This paper presents a 12 step framework for documenting the search strategy prior to undertaking a critique and synthesis of the retrieved literature. The authors provide a worked example about potential sources of cross contamination including hospital bath basins and soap and water bathing. DISCUSSION An overview of the 12 step framework is presented. This includes step-by-step instructions on how to conduct and write a search strategy for a literature review. A number of resources available for creating reviews and critiquing reviews are referenced, but these are not exclusive. CONCLUSION Reviews can be an important and valuable contribution when undertaken well, providing the reader with evidence of a clear structure. This paper provides a 12 step framework that will be of benefit to students, educationalists, and researchers required to embark on a review.

Abstract
Prolonged human spaceflight to another planet or an asteroid will introduce unique challenges of mitigating the risk of infection. During space travel, exposure to microgravity, radiation, and stress alter human immunoregulatory responses, which can in turn impact an astronaut's ability to prevent acquisition of infectious agents or reactivation of latent infection. In addition, microgravity affects virulence, growth kinetics, and biofilm formation of potential microbial pathogens. These interactions occur in a confined space in microgravity, providing ample opportunity for heavy microbial contamination of the environment. In addition, there is the persistence of aerosolized, microbe-containing particles. Any mission involving prolonged human spaceflight must be carefully planned to minimize vulnerabilities and maximize the likelihood of success.

Abstract
BACKGROUND Chlorhexidine gluconate (CHG) bathing has been used primarily in critical care to prevent central line-associated bloodstream infections and infections due to multidrug-resistant organisms. The objective was to determine the effect of hospital-wide CHG patient bathing on healthcare-associated infections (HAIs). DESIGN Quasi-experimental, staged, dose-escalation study for 19 months followed by a 4-month washout period, in 3 cohorts. SETTING Academic medical center. PATIENTS All patients except neonates and infants. INTERVENTION AND MEASUREMENTS CHG bathing in the form of bed basin baths or showers administered 3 days per week or daily. CHG bathing compliance was monitored, and the rate of HAIs was measured. RESULTS Over 188,859 patient-days, 68,302 CHG baths were administered. Adherence to CHG bathing in the adult critical care units (90%) was better than that observed in other units (57.7%, [Formula: see text]). A significant decrease in infections due to Clostridium difficile was observed in all cohorts of patients during the intervention period, followed by a significant rise during the washout period. For all cohorts, the relative risk of C. difficile infection compared to baseline was 0.71 (95% confidence interval [CI], 0.57-0.89; [Formula: see text]) for 3-days-per-week CHG bathing and 0.41 (95% CI, 0.29-0.59; [Formula: see text]) for daily CHG bathing. During the washout period, the relative risk of infection was 1.85 (95% CI, 1.38-2.53; [Formula: see text]), compared to that with daily CHG bathing. A consistent effect of CHG bathing on other HAIs was not observed. No adverse events related to CHG bathing were reported. CONCLUSIONS CHG bathing was well tolerated and was associated with a significant decrease in C. difficile infections in hospitalized patients.
