Boyce JM, Pittet D. Rinse, gel, and foam - is there any evidence for a difference in their effectiveness in preventing infections? Antimicrob Resist Infect Control 2024; 13:49. [PMID: 38730473 PMCID: PMC11084031 DOI: 10.1186/s13756-024-01405-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Accepted: 05/01/2024] [Indexed: 05/12/2024] Open
Abstract
BACKGROUND Following publication of the 2009 World Health Organizations Guidelines for Hand Hygiene in Health Care, a debate has emerged regarding the relative antimicrobial efficacy of the different formats (rinse, gel, foam) of ABHRs and their ability to contribute to reduction of healthcare-associated infections (HAIs). METHODS Data regarding the in-vivo antimicrobial efficacy of ABHRs and other factors that likely affect their effectiveness in reducing HAIs were reviewed, and a comprehensive review of studies that reported the effectiveness of each of the three ABHR formats to improve hand hygiene compliance and reduce HAIs was conducted. RESULTS The amount of rubbing time it takes for hands to feel dry (dry time) is the major driver of ABHR antimicrobial efficacy. ABHR format is not a major factor, and several studies found that rinse, gel, and foam ABHRs have comparable in-vivo antimicrobial efficacy. Other factors that likely impact the ability of ABHRs to reduce transmission of healthcare-associated pathogens and HAIs include ABHR formulation, the volume applied to hands, aesthetic characteristics, skin tolerance, acceptance by healthcare personnel, and hand hygiene compliance rates. When accompanied by complementary strategies, promoting the use of each of the three ABHR formats has been associated with improvements in hand hygiene compliance rates. A review of 67 studies failed to identify an ABHR format that was significantly more effective in yielding statistically significant reductions in transmission of healthcare-associated pathogens or HAIs. CONCLUSIONS Current evidence is insufficient to definitively determine if one ABHR format is more effective in reducing transmission of healthcare-associated pathogens and HAIs. More rigorous studies such as multicenter randomized controlled trials comparing the different formats are needed to establish if one format is significantly more effective in reducing HAIs.

Abstract
BACKGROUND Healthcare-associated infections (HAIs) burden healthcare globally. Amid the SARS-CoV-2 pandemic, intensified infection control measures, such as mask usage and hand hygiene, were implemented. AIM To assess the efficacy of these measures in preventing HAIs among hospitalized patients. METHODS Using the PICO framework (Population, Intervention, Comparison, Outcome), the study focused on hospitalized patients and the effectiveness of anti-COVID-19 measures in preventing HAIs. A systematic review of literature published in 2020-2022 was conducted, examining interventions such as mask usage, hand hygiene, and environmental cleaning. FINDINGS This systematic review analysed 42 studies: two in 2020, 21 in 2021, and 19 in 2022. Most studies were from high-income countries (28). Most studies (30 out of 42) reported a reduction in HAIs after implementing anti-COVID-19 measures. Gastrointestinal infections and respiratory tract infections showed significant reduction, unlike bloodstream infections and urinary tract infections. Some wards, like cardiology and neurology, experienced reduced HAIs, unlike intensive care units and coronary care units. There was an increase in studies reporting no effect of hygiene measures on HAIs in 2022, eventually indicating a shift in effectiveness over time. CONCLUSION Anti-COVID-19 measures have shown selective efficacy in preventing HAIs. The study emphasizes the need for context-specific strategies and increased focus on regions with limited resources. Continued research is essential to refine infection control practices, especially in high-risk settings.

Abstract
Introduction Bloodstream infections caused by methicillin-resistant Staphylococcus aureus (MRSA) remain a major challenge in most countries worldwide. Setting We describe a quasi-experimental sequential intervention at Mater Dei Hospital, Malta, to reduce hyper-prevalence of healthcare-associated MRSA bacteremia (HA-MRSA-B). Interventions The hospital initiated a hand hygiene (HH) campaign in 2008 to improve alcohol hand rub (AHR) use. In 2011, this was followed by root cause analysis (RCA) of all HA-MRSA-B cases and finally universal MRSA admission screening in 2014. Change-point analysis was used to evaluate the impact of the interventions. Results The effect of the HH campaign became evident when AHR consumption reached 40 L/1000 occupied bed days (BD). RCAs identified intravascular devices as the likely risk factor in 83% of all HA-MRSA-B; specifically non-tunneled double-lumen hemodialysis catheters (36%), peripheral venous cannulas (25%), and central venous catheters (22%). Interventions to improve their management resulted in the greatest reduction of HA-MRSA-B rates. They were informed by the RCA findings and targeted behavior change through education, motivation, and system change. Universal MRSA admission screening provided the final decline in incidence. Each intervention affected HA-MRSA-B rates after a lag period of approximately 18-24 months. Overall, HA-MRSA-B incidence decreased from 1.72 cases/10000BD in 2008 to 0.18/10000BD in 2019; a reduction of almost 90%. Intravenous device interventions were also associated with a reduction of methicillin-sensitive Staphylococcus aureus (MSSA) bacteremia rates. Conclusions Significant improvement in HA-MRSA-B is possible, even in highly endemic regions. It requires well-planned behavior change interventions which are compatible with local context and culture.

The effect of compliance to Hand hygiene during COVID-19 on intestinal parasitic infection and intensity of soil transmitted helminthes, among patients attending general hospital, southern Ethiopia: Observational study. PLoS One 2022; 17:e0270378. [PMID: 35767582 PMCID: PMC9242515 DOI: 10.1371/journal.pone.0270378] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Accepted: 06/08/2022] [Indexed: 12/16/2022] Open
Abstract
Background Intestinal parasitic infection (IPIs) is one of the major health problems in Sub -Saharan Africa where water, sanitation and hygiene practices are inadequate. Taking into account the national level implementation of intensive hand hygiene against COVID-19 pandemic and general protective effect this study assessed its effect on intestinal parasite. Objective This study aim to investigate the effect of compliance to hand hygiene practice on the prevalence of intestinal parasitic infection (IPIs) and intensity of Soil transmitted helminthes (STH) among patients attending tertiary care hospital in southern Ethiopia. Methods Observational study was conducted from June to September 2021. Data on socio demographic, hand hygiene practice and intestinal parasite (prevalence and intensity of helminthic infection) was collected from randomly selected and consented patients. Compliance to hand hygiene practice was assessed using pre-tested questionnaire. Fresh stool sample from each participant was examined by direct wet mount, concentration and Ziehl-Neelson (ZN) staining technique to detect intestinal parasite. Intensity of STH measurements was done through direct egg-count per gram using Kato Katz methods. Data analysis was done using SPSS version 25. Odds ratio with 95% confidence interval was used to measure association and p-value <0.05 was considered as statistically significant. Results The study population (N = 264) consisted of 139(52.65%) male and 125 (47.34%) female with the mean ages of 36 ±16.12(±SD). The proportion of good compliance to hand hygiene during COVID-19 to was 43.93% (95%CI: 37% to 47) and prevalence of intestinal parasite was 26.14% (95%CI:21.2% to 31.75) comprising 23.48% intestinal protozoa and 6.43% of soil transmitted helminthic infection. Gardia lamblia, Entamoeba histolytica/dispar, Ascaris lumbricoides were the common parasite in the study area with prevalence of 15.53%, 6.44%, and 1.52% respectively. Prevalence of intestinal parasite among participants with good compliance to hand hygiene group and poor compliance to hand hygiene were (14.65% vs. 35.13%)(AOR: 0.48,95%CI:0.13 to 0.68) (p = 0.002) implying that good compliance to hand hygiene can reduce the risk of IPIs by 52%. Moreover significantly lower odds of intestinal protozoa among good compliance to hand hygiene group than the control (OR:0.38; (95%CI: 0.20 to 0.71);P = 0.001. However, no significant difference in the odds of intensity of STH infection in good compliance hand hygiene and poor compliance group. The result of this study also confirmed the association between intestinal parasitic infections and younger /adolescent age, education status, habit of eating raw vegetable and figure nail status. Conclusion Good hand hygiene compliance during COVID-19 significantly associated with reduction of intestinal parasitic infection. This finding highlights the secondary protective effect of improved hand hygiene against IPIs and suggest it can used in augmenting the existing parasitic control strategies in the study setting.

Abstract
Background Hospital acquired infections are common, costly, and potentially preventable adverse events. This study aimed to determine the effect of the COVID-19 pandemic-related escalation in infection prevention and control measures on the incidence of hospital acquired infection in surgical patients in a low COVID-19 environment in Australia. Method This was a retrospective cohort study in a tertiary institution. All patients undergoing a surgical procedure from 1 April 2020 to 30 June 2020 (COVID-19 pandemic period) were compared to patients pre-pandemic (1 April 2019–30 June 2019). The primary outcome investigated was odds of overall hospital acquired infection. The secondary outcome was patterns of involved microorganisms. Univariable and multivariable logistic regression analysis was performed to assess odds of hospital acquired infection. Results There were 5945 admission episodes included in this study, 224 (6.6%) episodes had hospital acquired infections in 2019 and 179 (7.1%) in 2020. Univariable logistic regression analysis demonstrated no evidence of change in odds of having a hospital acquired infection between cohorts (OR 1.08, 95% CI 0.88–1.33, P = 0.434). The multivariable regression analysis adjusting for potentially confounding co-variables also demonstrated no evidence of change in odds of hospital acquired infection (OR 0.93, 95% CI 0.74–1.16, P = 0.530). Conclusion Increased infection prevention and control measures did not affect the incidence of hospital acquired infection in surgical patients in our institution, suggesting that there may be a plateau effect with these measures in a system with a pre-existing high baseline of practice.

Abstract
Introduction This study evaluates the impact of an Internet of Things (IoT) intervention in a hospital unit and provides empirical evidence on the effects of smart technologies on patient safety (patient falls and hand hygiene compliance rate) and staff experiences. Method We have conducted a post-intervention analysis of hand hygiene (HH) compliance rate, and a pre-and post-intervention interrupted time-series (ITS) analysis of the patient falls rates. Lastly, we investigated staff experiences by conducting semi-structured open-ended interviews based on Roger’s Diffusion of Innovation Theory. Results The results showed that (i) there was no statistically significant change in the mean patient fall rates. ITS analysis revealed non-significant incremental changes in mean patient falls (− 0.14 falls/quarter/1000 patient-days). (ii) HH compliance rates were observed to increase in the first year then decrease in the second year for all staff types and room types. (iii) qualitative interviews with the nurses reported improvement in direct patient care time, and a reduced number of patient falls. Conclusion This study provides empirical evidence of some positive changes in the outcome variables of interest and the interviews with the staff of that unit reported similar results as well. Notably, our observations identified behavioral and environmental issues as being particularly important for ensuring success during an IoT innovation implementation within a hospital setting.

Abstract
Background Patients at intensive care units (ICUs) are vulnerable to acquiring nosocomial infections. The main objective of this study was to explore and characterize the burden of nosocomial infections from an ICU of National Medical College and Teaching Hospital (NMCTH), Birgunj, Nepal. Methods A prospective hospital-based study was conducted between April and December 2018 at NMCTH, Birgunj, Province 2, of Nepal. A total of 374 specimens including clinical specimens (n = 190) from patients admitted in an ICU and animate and inanimate environmental samples (n = 184) from the ICU were collected. Collected specimens were cultured in specific microbiological media, and microbial isolates were identified and subjected to antibiotic susceptibility test. Results Altogether, 374 specimens (190 clinical specimens and 184 nonclinical) of an ICU were analyzed. Out of 190 clinical specimens, 51% (97/190) showed bacterial growth. Isolated bacteria were Staphylococcus aureus (33%; 32/97), Escherichia coli (20.6%; 20/97), Klebsiella spp. (15.5%; 15/97), Pseudomonas spp. (11.3%; 11/97), and Acinetobacter spp. (11.3%; 11/97). Out of 184 nonclinical specimens, 51.6% (95/184) of the samples showed microbial growth. Among the isolates, Klebsiella spp. predominated (30.6%; 26/85) the growth, followed by S. aureus (22.4%; 19/85), Acinetobacter spp. (21.2%; 18/85), and Pseudomonas spp. (17.6%; 15/85). Among all clinical and nonclinical isolates, 61.9% (60/97) of the clinical specimens and 65.9% (56/85) of the nonclinical specimens showed multidrug resistance (MDR). Conclusion Two-thirds of the specimens from both clinical and nonclinical specimens showed MDR. Urgent actions are required to address the augmented rate of nosocomial infections and MDR bacteria among ICUs in Nepal.

Abstract
BACKGROUND Healthcare worker's (HCW) hands are known to be a primary source of transmission of hospital-acquired infections (HAIs). Thus, practicing hand hygiene (HH) and adhering to HH guidelines are both expected to decrease the risk of transmission but there is no consensus on the optimal hand hygiene compliance (HHC) rate that HCWs should aim for. AIM The objective of this study was to systematically review the published literature to determine an optimal threshold of HCW HHC rate associated with the lowest incidence rate of HAIs. METHODS This systematic review was performed according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. We searched online databases using a comprehensive search criterion for randomized controlled trials and non-randomized controlled studies, investigating the impact of HCW's HHC rate on HAI rates in patients of all ages, within healthcare facilities in high income countries. FINDINGS Of the 8,093 articles citations and abstracts screened, 35 articles were included in the review. Most studies reported overall HAIs per 1000 patient-days and device-associated HAIs per 1000 device-days. Most studies reported HHC rates between 60%-70%. Lower incidence HAI rates seemed to be achieved with HHC rates of approximately 60%. Studies included were not originally designed to assess the impact of HHC on HAI rates but risk of bias was assessed as per our predetermined exposure and outcome criterion. 11 (31%) of studies were deemed at low risk of bias. CONCLUSIONS Although HHC is part of HCW's code of conduct, very high HHC rates were difficult to reach. In observational studies, HHC and HAI followed a negative relationship up to about 60%. Due to flaws in study design, causality could not be inferred; only general trends could be discussed. Given the limitations, there is a need for high-quality evidence to support the implementation of specified targets of HHC rates.

Abstract
Introduction
Compliance to hand hygiene (HH) is an important measure in preventing infections to patients in health-care settings. Wellness and safety of patients and health-care workers (HCWs) can be achieved by promoting best practices in infection control through education and advocacy.
Aims and Objectives
To assess the compliance to HH among all cadres of HCWs and its association with hospital-acquired infection (HAI) in patients.
Materials and Methods
A prospective, observational study was conducted for a period of 5 years (January 2014 to December 2018) in Neuro Trauma intensive care unit. A standard checklist based on World Health Organization’s 5 Moments for Hand Hygiene was used as a tool to measure the HH compliance.
Results
HAI rate was found to be directly proportional to the compliance to HH. Reduction in HAI rates was reported when there was an increase in HH compliance. HAI of 4.25% was found to be lowest in the year 2015 with the compliance to HH of 63.65%. The HH compliance was also found to be highest (64.63%) in the year 2016 followed by 64.12% in the year 2017. During this period HAI rates were 4.35% and 4.8%, respectively. When the HH compliance declined in the year 2018 to 53.95%, there was an increase in the rate of HAI to 6.9%.
Conclusion
It could be concluded that HH compliance was associated with the decrease in HAIs. HH could be a simple and cost-effective method in the prevention of HAIs.

[PMID: 34428506 DOI: 10.1016/j.jhin.2021.08.015] [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: 05/14/2021] [Revised: 07/12/2021] [Accepted: 08/16/2021] [Indexed: 01/11/2023]
Abstract
BACKGROUND Hand hygiene remains both the major strategy and an ongoing challenge for infection control. The main issues in the sustainability of hand hygiene automatic monitoring are healthcare worker (HCW) turnover rates and declining participation. AIM To assess hand hygiene compliance and the impact of real-time reminders over three years. METHODS HCW compliance was observed for the use of alcohol-based hand rubs (AHR) on room entry and exit. Linear multi-level mixed models with time autocorrelations were performed to analyse the repeated measurements of daily room compliance and the effect of reminders over eight quarters (24 months). FINDINGS In all, 111 HCWs were observed and 525,576 activities were identified in the database. There was an improvement in compliance both on room entry and exit over two years, and the rooms which had activated reminders had better performance than the rooms which did not have activated reminders. CONCLUSIONS This study showed the benefit of using real-time reminders; even 20% of rooms with an activated reminder improved overall hand hygiene compliance. A randomized real-time reminder setting may be a potential solution in reducing user fatigue and enhancing HCW self-awareness.

Reorganization of nurse scheduling reduces the risk of healthcare associated infections. Sci Rep 2021; 11:7393. [PMID: 33795708 PMCID: PMC8016903 DOI: 10.1038/s41598-021-86637-w] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Accepted: 03/18/2021] [Indexed: 11/21/2022] Open
Abstract
Efficient prevention and control of healthcare associated infections (HAIs) is still an open problem. Using contact data from wearable sensors at a short-stay geriatric ward, we propose a proof-of-concept modeling study that reorganizes nurse schedules for efficient infection control. This strategy switches and reassigns nurses’ tasks through the optimization of shift timelines, while respecting feasibility constraints and satisfying patient-care requirements. Through a Susceptible-Colonized-Susceptible transmission model, we found that schedules reorganization reduced HAI risk by 27% (95% confidence interval [24, 29]%) while preserving timeliness, number, and duration of contacts. More than 30% nurse-nurse contacts should be avoided to achieve an equivalent reduction through simple contact removal. Nurse scheduling can be reorganized to break potential chains of transmission and substantially limit HAI risk, while ensuring the timeliness and quality of healthcare services. This calls for including optimization of nurse scheduling practices in programs for infection control in hospitals.

Abstract
Background Central line-associated bloodstream infection (CLABSI) is an important cause of increased morbidity and mortality in ICUs. The occurrence of CLABSI in significantly higher in developing countries and contributes to the burden of healthcare-associated infections. Methods This prospective study was carried out from January 2016 to December 2019 in the intensive care unit at King Faisal Medical Complex in Taif, Saudi Arabia. The Society for Healthcare Epidemiology of America/Infectious Diseases Society of America (SHEA/IDSA) recommendations were introduced and implemented during 2017–2019. In the post-intervention period, observation of hand hygiene, CLABSI bundle compliance, and benchmarking of CLABSI rates were carried out. Results The CLABSI incidence rate was 1.12/1,000 central-line days, with a 0.51 utilization ratio in the pre-intervention period. This dropped to 0.46/1,000 central line days with a 0.44 utilization ratio in the post-intervention period. This reduction was also confirmed in benchmarking with National Healthcare Safety Network (NHSN) (50th–75th) percentile pre-intervention vs (25th–50th) percentile post-intervention. Institutional risk assessment revealed a formal educational program as a potential need for improvement. The CLABSIs were caused predominantly by multidrug-resistant Klebsiella pneumoniae. Conclusion We observed a reduction and sustained low incidence rate of CLABSI benchmarking to NHSN for 3 years after implementation of the basic SHEA/IDSA recommendations.

Abstract
BACKGROUND Worldwide, bacterial bloodstream infections (BSIs) constitute an important cause of morbidity and mortality in clinical settings. Due to the limited laboratory facilities in sub-Saharan Africa, poor diagnosis of BSIs results in poor clinical outcomes and leads to a risk of antimicrobial resistance. The present work was carried out to describe the microbiological features of BSIs using the data collected from Centre Hospitalier Universitaire de Kigali (CHUK). METHODS A retrospective study was carried out at CHUK. The blood culture results of 2,910 cases - from adults, children and infants - were reviewed in the Microbiology service from October 2017 to October 2018. The following variables were considered: age, gender, admitting department, blood culture results, and antimicrobials sensitivity test results. Data were entered and analyzed using Microsoft Excel 2013. RESULTS Twelve percent (341/2,910) of blood culture results reviewed were positive with 108 (31.7%) Gram positive bacteria and 233 (68.3%) Gram negative bacteria. The most prevalent pathogens were Klebsiella pneumoniae 108 (31.7%) and Staphylococcus aureus 100 (29.3%). This study revealed a high resistance to commonly prescribed antibiotics such as penicillin, trimethoprim sulfamethoxazole, and Ampicillin with 91.8, 83.3, and 81.8% of resistance, respectively. However, bacteria were sensitive to imipenem and vancomycin with 98.1 and 94.3% of sensitivity, respectively. The pediatrics and neonatology departments showed a high number of positive culture with 97/341 (28.4%), and 93/341 (27%) respectively. The overall prevalence of multidrug resistance was 77.1%. CONCLUSION The prevalence of bacterial pathogens in BSIs was found to be high. The antibiotic resistance to the commonly used antibiotics was high. Appropriate treatment of BSIs should be based on the current knowledge of bacterial resistance pattern. This study will help in formulating management of diagnostic guidelines and antibiotic policy.

Abstract
Healthcare-associated infections (HCAIs) are a major source of morbidity and mortality and are the second most prevalent cause of death. Furthermore, it has been reported that for every one-hundred patients admitted to hospital, seven patients in high-income economies and ten in emerging and low-income economies acquire at least one type of HCAI. Currently, almost all pathogenic microorganisms have developed antimicrobial resistance, and few new antimicrobials are being developed and brought to market. The literature search for this narrative review was performed by searching bibliographic databases (including Google Scholar and PubMed) using the search terms: "Strategies," "Prevention," and "Healthcare-Associated Infections," followed by snowballing references cited by critical articles. We found that although hand hygiene is a centuries-old concept, it is still the primary strategy used around the world to prevent HCAIs. It forms one of a bundle of approaches used to clean and maintain a safe hospital environment and to stop the transmission of contagious and infectious microorganisms, including multidrug-resistant microbes. Finally, antibiotic stewardship also has a crucial role in reducing the impact of HCAIs through conserving currently available antimicrobials.

Abstract
Purpose Salmonella enterica serovar Typhimurium infection is common in foodborne diseases, but its isolation from surgical incisions is rare. Our aim in this study was to trace the transmission source of a surgical incision infected with S. Typhimurium in a Yunnan Province hospital patient and elucidate the underlying molecular mechanisms of antibiotic resistance. Methods Primers were designed to amplify the drug-resistance genes using polymerase chain reaction (PCR). Susceptibility to antibiotics was determined using Etest strips. Macrorestriction profiles were analyzed using pulsed-field gel electrophoresis (PFGE) and XbaI. The two isolates were characterized using agglutination tests and multilocus sequence typing (MLST). Results MLST analysis revealed that S. Typhimurium isolates SM043 and SM080 belonged to the same genotype, ST34, and PFGE revealed that SM043 and SM080 had high similarity. The isolates were both resistant to third-generation cephalosporins. SM043 harbored the antibiotic resistance genes blaCTX-M-15, blaTEM-1, qnrS-1, qnrB, and acc-3, whereas blaCTX-M-15, blaTEM-1, blaCMY-2, qnrS-1, and acc-3 were detected in SM080. Conclusion The surgical incision infection by S. Typhimurium may have been hospital-acquired. Thus, it is critical to strengthen hospital sanitation by addressing hand hygiene and sterilization of the operational environment to avoid outbreaks of nosocomial Salmonella infections.

Abstract
BACKGROUND Maintaining optimal infection prevention and control (IPC) in a busy, clinical environment is challenging. Video-reflexive ethnography (VRE) is a collaborative, interventionist approach to practice improvement. We hypothesised that giving clinicians opportunities to view and reflect on video footage of everyday ward activities would raise awareness of, and suggest strategies to reduce, pathogen transmission risks. We undertook a VRE project, between March and September 2013, in two tertiary hospital surgical wards, with persistently high methicillin resistant Staphylococcus aureus (MRSA) endemicity, despite previous IPC interventions. METHODS This study was a retrospective/prospective observational study, using interrupted time-series analyses, to assess the effects of the VRE project on hand hygiene compliance, inpatient MRSA infections (newly infected patients, per 1000 occupied bed days) and inpatient MRSA colonisation prevalence, measured by serial point prevalence surveys. Follow-up continued until June 2016. RESULTS The VRE project was associated with changes in IPC behaviour and outcomes. Hand hygiene compliance increased (from 62% to 75%; p < 0.0001) and MRSA colonisation prevalence decreased significantly, in both wards (baseline 42%; average post-VRE 12%; p=<0.0001), MRSA infection rate decreased in one ward. Interpretation of results was complicated by a potential confounding effect of unplanned environmental hydrogen peroxide decontamination (HPD). Improved hand hygiene compliance was a predicted outcome of VRE, but also a potential contributor to reduced MRSA transmission. CONCLUSION Separate contributions of VRE (the intervention), HPD and hand hygiene compliance were uncertain, but their combined effect was significantly reduced MRSA endemicity, which previously had been resistant to attempted IPC interventions.

Abstract
Health care-associated infections (HCAIs) are infections that occur while receiving health care, developed in a hospital or other health care facility that first appear 48 hours or more after hospital admission, or within 30 days after having received health care. Multiple studies indicate that the common types of adverse events affecting hospitalized patients are adverse drug events, HCAIs, and surgical complications. The US Center for Disease Control and Prevention identifies that nearly 1.7 million hospitalized patients annually acquire HCAIs while being treated for other health issues and that more than 98,000 patients (one in 17) die due to these. Several studies suggest that simple infection-control procedures such as cleaning hands with an alcohol-based hand rub can help prevent HCAIs and save lives, reduce morbidity, and minimize health care costs. Routine educational interventions for health care professionals can help change their hand-washing practices to prevent the spread of infection. In support of this, the WHO has produced guidelines to promote hand-washing practices among member countries.

Abstract
This article reports on a study of clinicians' responses to footage of their enactments of infection prevention and control. The study's approach was to elicit clinicians' reflections on and clarifications about the connections among infection control activities and infection control rules, taking into account their awareness, interpretation and in situ application of those rules. The findings of the study are that clinicians responded to footage of their own infection prevention and control practices by articulating previously unheeded tensions and constraints including infection control rules that were incomplete, undergoing change, and conflicting; material obstructions limiting infection control efforts; and habituated and divergent rule enactments and rule interpretations that were problematic but disregarded. The reflexive process is shown to elicit clinicians' learning about these complexities as they affect the accomplishment of effective infection control. The process is further shown to strengthen clinicians' appreciation of infection control as necessitating deliberation to decide what are locally appropriate standards, interpretations, assumptions, habituations and enactments of infection control. The article concludes that clinicians' 'practical wisdom' is unlikely to reach its full potential without video-assisted scrutiny of and deliberation about in situ clinical work. This enables clinicians to anchor their in situ enactments, reasonings and interpretations to local agreements about the intent, applicability, limits and practical enactment of rules.

Abstract
PURPOSE OF REVIEW Hospital-acquired pneumonia and ventilator-associated pneumonia remain significant causes of morbidity, mortality, and financial burden in the United States and around the globe. Although guidelines for the management of patients with these conditions have been available for several years, implementation remains challenging. Here, we review the most common barriers faced by clinicians in implementing the current guidelines and offer suggestions for improved adherence. RECENT FINDINGS Recent studies have identified barriers to the implementation of the guidelines regarding management of hospital-acquired and ventilator-associated pneumonia. The most common difficulties encountered are lack of awareness of the guidelines, practice variation among providers delivering care to affected patients, lack of antibiogram information, and lack of antibiotic stewardship programs. SUMMARY Translating the current hospital-acquired and ventilator-associated pneumonia guidelines to the bedside requires understanding of the current barriers affecting care of patients with these conditions. Adopting clinical guidelines facilitates the management of these patients and improves outcomes. Dissemination of the guidelines, provider education, antibiotic stewardship programs, access to local antibiogram information, audit and feedback, electronic tools and leadership commitment are likely to play important roles in guideline implementation. More studies on hospital-acquired and ventilator-associated pneumonia guideline implementation are necessary to identify the most effective interventions.

Abstract
Background: In an attempt to defeat the high prevalence of health care associated infections, by raising the awareness about hand hygiene, we implemented a quasi-experimental study as part of a quality improvement project to evaluate the efficacy of focused educational workshop on knowledge about hand hygiene among health care workers in Sudan. Methods: Seventy-three participants were recruited from two public hospitals and one private hospital in Khartoum, Sudan in September 2017. The knowledge before and after the educational workshop was assessed for each participant using the World Health Organization hygiene associated infection questionnaire. We analyzed data using SPSS v22 and used McNemar’s test to compare knowledge before and after the workshop. Results: Around 40% of participants worked in general ward and 85% of them were women. Almost 70% were midwives or nurses. The mean age of participants was 28.4 years. We compared the knowledge of hand hygiene between nurses and doctors before the workshop, and the results showed that nurses had better knowledge in almost all aspects of hand hygiene. When we compared the knowledge before and immediately after the workshop for all participants, we found that there was no significant improvement in almost all aspects of knowledge about hand hygiene (P>0.05). Conclusion: Comparing the knowledge before and after the workshop, we found no significant improvement in almost all aspects of hand hygiene. Of note, nurses’ knowledge about hand hygiene was consistently higher than doctors. Additional studies are needed to identify the optimal design of educational sessions.

Abstract
Alcohol-based disinfectants play an important role in the prevention of healthcare-acquired infection (HAI). We investigated whether pathogens present in mucus acquire resistance to alcohol-based disinfectants, and elucidated the underlying mechanism. Both the resistance of influenza A virus and Escherichia coli to alcohol-based disinfectants or ultraviolet irradiation and the diffusion rate of ethanol were determined in artificial mucus or sputum samples obtained from 27 individuals with acute upper respiratory infection. Pathogens in mucus (artificial mucus or sputum samples) were not completely inactivated by alcohol-based disinfectants (survival rate >10%), suggesting that the alcohol-based disinfectants were ineffective. Pathogen survival and mucus viscosity were strongly correlated (correlation coefficient >0.7, P < 0.001). Additionally, the ethanol diffusion rate decreased with increasing mucus viscosity, which contributed to ethanol resistance. Pronase treatment of sputum samples significantly decreased sputum viscosity and increased the disinfectant effect (P < 0.001 for all). In contrast, complete inactivation was achieved by ultraviolet irradiation independently of mucus viscosity. Thus, mucus viscosity contributes to resistance of pathogens to alcohol-based disinfectants by decreasing the alcohol diffusion rate. These findings can provide a basis for developing new strategies, including improved disinfectants, for overcoming HAI.

Abstract
Transcriptional profiles of 2 unrelated clinical methicillin-resistant Staphylococcus aureus (MRSA) isolates were analyzed following 10% (v/v) ethanol challenge (15 min), which arrested growth but did not reduce viability. Ethanol-induced stress (EIS) resulted in differential gene expression of 1091 genes, 600 common to both strains, of which 291 were upregulated. With the exception of the downregulation of genes involved with osmotic stress functions, EIS resulted in the upregulation of genes that contribute to stress response networks, notably those altered by oxidative stress, protein quality control in general, and heat shock in particular. In addition, genes involved with transcription, translation, and nucleotide biosynthesis were downregulated. relP, which encodes a small alarmone synthetase (RelP), was highly upregulated in both MRSA strains following ethanol challenge, and relP inactivation experiments indicated that this gene contributed to EIS growth arrest. A number of persistence-associated genes were also upregulated during EIS, including those that encode toxin-antitoxin systems. Overall, transcriptional profiling indicated that the MRSA investigated responded to EIS by entering a state of dormancy and by altering the expression of elements from cross protective stress response systems in an effort to protect preexisting proteins.

Abstract
OBJECTIVE Within the framework of the PaSQ (Patient Safety and Quality care) Project, this hospital decided to implement a multifaceted hospital-wide Hand Hygiene (HH) intervention based on a multimodal WHO approach over one year, focusing on achieving a sustained change in HH cultural change in this hospital. MATERIAL AND METHODS Setting: University Hospital Marqués de Valdecilla, Santander (Spain), a tertiary hospital with 900 beds. Intervention period: 2014. An action plan was developed that included the implementation of activities in each component of the 5-step multimodal intervention. An observation/feedback methodology was used that included the provision of performance and results feedback to the staff. A 3/3 strategy (non-blinded direct observation audits performed during 3 randomised days every 3 weeks with pro-active corrective actions at the end of each observation period). HH compliance, alcohol-based hand-rub (ABHR) consumption, and rate of MRSA infection, were monitored during the intervention. RESULTS Hospital ABHR consumption increased during the study period: from 17.5 to 19.7mL/patient-days. In the intervention units, this consumption was 24.8mL pre-intervention, 42.5mL during the intervention, and 30.4mL two months post-intervention. There were 137 evaluation periods in 30 different days, in which a total of 737 health-care workers were observed and 1,870 HH opportunities. HH compliance was 54.5%, ranging between 44.8% and 69.9%. The incidence of MRSA infection decreased during the intervention in the selected units, from 13.2 infections per 10,000 patient-days pre-intervention to 5.7 three months post-intervention. CONCLUSIONS Our HH strategy, supported by a 3/3 strategy increased alcohol-based hand-rub consumption and compliance. A reduction in MRSA infections was observed.

Abstract
BACKGROUND Human auditing and collating hand hygiene compliance data take hundreds of hours. We report on 24/7 overt observations to establish adjusted average daily hand hygiene opportunities (HHOs) used as the denominator in an automated surveillance that reports daily compliance rates. METHODS Overt 24/7 automated surveillance collected HHOs in medical and surgical wards. Accredited auditors observed health care workers' interaction between patient and patient zones to collect the total number of HHOs, indications, and compliance and noncompliance. Automated surveillance captured compliance (ie, events) via low power radio connected to alcohol-based handrub (ABHR) dispensers. Events were divided by HHOs, adjusted for daily patient-to-nurse ratio, to establish daily rates. RESULTS Human auditors collected 21,450 HHOs during 24/7 with 1,532 average unadjusted HHOs per day. This was 4.4 times larger than the minimum ward sample required for accreditation. The average adjusted HHOs for ABHR alone on the medical ward was 63 HHOs per patient day and 40 HHOs per patient day on the surgical ward. From July 1, 2014-July 31, 2015 the automated surveillance system collected 889,968 events. CONCLUSIONS Automated surveillance collects 4 times the amount of data on each ward per day than a human auditor usually collects for a quarterly compliance report.

Abstract
BACKGROUND To understand whether the burden of hand hygiene contributes to poor compliance we measured the daily number of hand hygiene opportunities (HHOs) by shift for nurses and physicians in 2 wards in a 850-bed university teaching hospital. METHODS On each ward 4 trained auditors collected the number of HHOs and compliance events for 24 hours over 7 days. Twenty-one thousand four hundred fifty HHOs were collected from a medical and a surgical ward. The proportion of alcohol-based handrub used daily, the burden of hand hygiene, and compliance rates were calculated separately for nurses and physicians. RESULTS The average indication for alcohol-based handrub cleansing represented 68% of all HHOs. Nurses had an average burden of 55 HHOs per 24 hours or 27 HHOs per shift, 3 times higher than the burden for physicians, who had 16 HHOs per 24 hours or 8 HHOs per shift. Overt observations of the weekly compliance identified nurses had 1.5 times higher compliance than physicians: 76% and 52% (P < .01), respectively. CONCLUSIONS Nurses have 3 times more HHOs than physicians, yet nurses have 1.5 times higher compliance than physicians. Hand hygiene compliance in physicians cannot be explained by burden of HHOs.

Abstract
ISSUE Hand hygiene is a cost-effective measure to reduce microbial transmission (Teare EL, Cookson B, French GL, et al. UK handwashing initiative. J Hosp Infect. 1999;43:1-3.) and is considered to be the most important measure to prevent healthcare-associated infections (Pittet D, Allegranzi B, Sax H, Evidence-based model for hand transmission during patient care and the role of improved practices. Lancet Infect Dis 2006;6:641-52). Unfortunately, the compliance rate of healthcare workers (HCWs) with recommended hand hygiene procedures is less than expected. INITIAL ASSESSMENT In order to estimate the effect of a multimodal intervention on improving healthcare workers' compliance with hand hygiene in eleven intensive care units (ICUs) from 11 hospitals of Buenos Aires, a randomized cluster-stepped wedge trial was designed. CHOICE OF SOLUTION AND IMPLEMENTATION A multimodal intervention was designed based on practices characterized by being evidence-based, low cost and suggested by qualitative research: (i) leadership commitment, (ii) surveillance of materials needed to comply with hand hygiene and alcohol consumption, (iii) utilization of reminders, (iv) a storyboard of the project and (v) feedback (hand hygiene compliance rate). EVALUATION The study enrolled 705 participants, comprising nurses (66.4%), physicians (25.8%) and other HCW (7.8%) along 9 months of observation. Compliance with hand hygiene in the control group was 66.0% (2354/3565) vs. 75.6% (5190/6864) in the intervention group. Univariate analysis showed an association between the intervention and hand hygiene compliance (odds ratio, OR 1.17; 95% confidence interval (CI), 1.13-1.22). The effect was still present after adjustment by calendar's time and providers' characteristics-age, gender and profession (OR 1.08; 95% CI, 1.03-1.14). LESSONS LEARNED His study supports that a multimodal intervention was effective to improve compliance with hand hygiene in ICUs.
