Abstract
BACKGROUND Health care-associated infection is a major cause of morbidity and mortality. Hand hygiene is regarded as an effective preventive measure. OBJECTIVES To update the review done in 2007, to assess the short and longer-term success of strategies to improve hand hygiene compliance and to determine whether a sustained increase in hand hygiene compliance can reduce rates of health care-associated infection. SEARCH STRATEGY We conducted electronic searches of: the Cochrane Central Register of Controlled Trials; the Cochrane Effective Practice and Organisation of Care Group specialised register of trials; MEDLINE; PubMed; EMBASE; CINAHL; and the BNI. Originally searched to July 2006, for the update databases were searched from August 2006 until November 2009. SELECTION CRITERIA Randomised controlled trials, controlled clinical trials, controlled before and after studies, and interrupted time series analyses meeting explicit entry and quality criteria used by the Cochrane Effective Practice and Organisation of Care Group were eligible for inclusion. Studies reporting indicators of hand hygiene compliance and proxy indicators such as product use were considered. Self-reported data were not considered a valid measure of compliance. Studies to promote hand hygiene compliance as part of a care bundle approach were included, providing data relating specifically to hand hygiene were presented separately. Studies were excluded if hand hygiene was assessed in simulations, non-clinical settings or the operating theatre setting. DATA COLLECTION AND ANALYSIS Two reviewers independently extracted data and assessed data quality. MAIN RESULTS Four studies met the criteria for the review: two from the original review and two from the update. Two studies evaluated simple education initiatives, one using a randomized clinical trial design and the other a controlled before and after design. Both measured hand hygiene compliance by direct observation. The other two studies were both interrupted times series studies. One study presented three separate interventions within the same paper: simple substitutions of product and two multifaceted campaigns, one of which included involving practitioners in making decisions about choice of hand hygiene products and the components of the hand hygiene program. The other study also presented two separate multifaceted campaigns, one of which involved application of social marketing theory. In these two studies follow-up data collection continued beyond twelve months, and a proxy measure of hand hygiene compliance (product use) was recorded. Microbiological data were recorded in one study. Hand hygiene compliance increased for one of the studies where it was measured by direct observation, but the results from the other study were not conclusive. Product use increased in the two studies in which it was reported, with inconsistent results reported for one initiative. MRSA incidence decreased in the one study reporting microbiological data. AUTHORS' CONCLUSIONS The quality of intervention studies intended to increase hand hygiene compliance remains disappointing. Although multifaceted campaigns with social marketing or staff involvement appear to have an effect, there is insufficient evidence to draw a firm conclusion. There remains an urgent need to undertake methodologically robust research to explore the effectiveness of soundly designed and implemented interventions to increase hand hygiene compliance.

Abstract
The objectives of this article were to review the causes and extent of hospital-associated infectious diarrhea and associated risks in the general hospital ward and intensive care unit (ICU), to compare microorganisms with similar symptoms to aid in recognition that will lead to timely and appropriate treatment and control measures, and to propose infection prevention protocols that could decrease human process errors in the ICU. This literature review describes epidemiology, comparison of microbial characteristics for potential hospital-associated enteric pathogens, diagnosis, and prevention, especially if important in the ICU, and particularly in regard to Clostridium difficile. Enteric organisms that most commonly cause hospital-associated infectious diarrhea in acute care settings and the ICU are C. difficile, rotavirus, and norovirus, although others may also be important, particularly in developing countries. To recognize and control infectious diarrhea successfully in the ICU, intensivists should be aware that epidemiology, risks, and prevention measures may differ between these microorganisms. In addition, intensivists should be ready to implement systems changes related to notification, isolation precautions and prevention, and environmental cleaning in the ICU.

Abstract
BACKGROUND Alcohol-based hand rubs (ABHRs) are an effective means of decreasing the transmission of bacterial pathogens. Alcohol is not effective against Clostridium difficile spores. We examined the retention of C. difficile spores on the hands of volunteers after ABHR use and the subsequent transfer of these spores through physical contact. METHODS Nontoxigenic C. difficile spores were spread on the bare palms of 10 volunteers. Use of 3 ABHRs and chlorhexidine soap-and-water washing were compared with plain water rubbing alone for removal of C. difficile spores. Palmar cultures were performed before and after hand decontamination by means of a plate stamping method. Transferability of C. difficile after application of ABHR was tested by having each volunteer shake hands with an uninoculated volunteer. RESULTS Plain water rubbing reduced palmar culture counts by a mean (+/- standard deviation [SD]) of 1.57 +/- 0.11 log10 colony-forming units (CFU) per cm2, and this value was set as the zero point for the other products. Compared with water washing, chlorhexidine soap washing reduced spore counts by a mean (+/- SD) of 0.89 +/- 0.34 log10 CFU per cm2; among the ABHRs, Isagel accounted for a reduction of 0.11 +/- 0.20 log10 CFU per cm2 (P = .005), Endure for a reduction of 0.37 +/- 0.42 log10 CFU per cm2 (P = .010), and Purell for a reduction of 0.14 +/- 0.33 log10 CFU per cm2 (P = .005). There were no statistically significant differences between the reductions achieved by the ABHRs; only Endure had a reduction statistically different from that for water control rubbing (P = .040). After ABHR use, handshaking transferred a mean of 30% of the residual C. difficile spores to the hands of recipients. CONCLUSIONS Hand washing with soap and water is significantly more effective at removing C. difficile spores from the hands of volunteers than are ABHRs. Residual spores are readily transferred by a handshake after use of ABHR.

Abstract
BACKGROUND We sought to determine the long-term impact of "bundled" infection control interventions on the rates of catheter-associated bloodstream infection (CA-BSI) in a middle-income country. SETTING A 500-bed tertiary care center in Thailand. METHODS A 3-year, hospital-wide, prospective quasi-experimental study was conducted for 1 year before the intervention (period 1), 1 year after implementation of the CA-BSI bundle (period 2), and at a 1-year follow-up after the intervention with intensified hand hygiene promotion (period 3). RESULTS In period 1, 88 episodes of CA-BSI (14 cases per 1000 catheter-days) were recorded. During period 2, the CA-BSI rate decreased by 54.1 % (6.4 cases per 1000 catheter-days; P <.001). Compared with period 1 (8% adherence), hand hygiene adherence was improved in period 2 (24%; P <.001) and period 3 (54%; P <.001). The CA-BSI rate was further decreased by 78% (1.4 cases per 1000 catheter-days; P <.001) during period 3. Notably, no CA-BSIs were seen in 6 of the 12 months (50%) of period 3. Compared with period 1, the mean number of catheter-days was significantly reduced in period 2 (4.9 +/- 1.5 days; P <.001) and period 3 (4.1 +/- 1.1 days; P <.001). CONCLUSION Bundled infection control practices are feasible and effective in sustaining reduced incidence of CA-BSI in patients with central venous catheters in a resource-limited setting.

Abstract
Determined actions are required to address the burden due to health care-associated infections worldwide and improve patient safety. Improving hand hygiene among health care workers is an essential intervention to achieve these goals. The World Health Organization (WHO) First Global Patient Safety Challenge, Clean Care is Safer Care, pledged to tackle the problem of health care-associated infection at its launch in 2005 and has elaborated a comprehensive set of guidelines for use in both developed and developing countries worldwide. The final version of the WHO Guidelines on Hand Hygiene in Health Care was issued in March 2009 and includes recommendations on indications, techniques, and products for hand hygiene. In this review, we discuss the role of hands in the transmission of health care-associated infection, the benefits of improved compliance with hand hygiene, and the recommendations, implementation strategies and tools recommended by WHO. We also stress the need for action to increase the pace with which these recommendations are implemented in facilities across India.

Abstract
The epidemiology of Clostridium difficile infection (CDI) has changed dramatically during this millennium. Infection rates have increased markedly in most countries with detailed surveillance data. There have been clear changes in the clinical presentation, response to treatment, and outcome of CDI. These changes have been driven to a major degree by the emergence and epidemic spread of a novel strain, known as PCR ribotype 027 (sometimes referred to as BI/NAP1/027). We review the evidence for the changing epidemiology, clinical virulence and outcome of treatment of CDI, and the similarities and differences between data from various countries and continents. Community-acquired CDI has also emerged, although the evidence for this as a distinct new entity is less clear. There are new data on the etiology of and potential risk factors for CDI; controversial issues include specific antimicrobial agents, gastric acid suppressants, potential animal and food sources of C. difficile, and the effect of the use of alcohol-based hand hygiene agents.

Abstract
Health care-associated infections (HAI) remain a major cause of patient morbidity and mortality. Although the main source of nosocomial pathogens is likely the patient's endogenous flora, an estimated 20% to 40% of HAI have been attributed to cross infection via the hands of health care personnel, who have become contaminated from direct contact with the patient or indirectly by touching contaminated environmental surfaces. Multiple studies strongly suggest that environmental contamination plays an important role in the transmission of methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus spp. More recently, evidence suggests that environmental contamination also plays a role in the nosocomial transmission of norovirus, Clostridium difficile, and Acinetobacter spp. All 3 pathogens survive for prolonged periods of time in the environment, and infections have been associated with frequent surface contamination in hospital rooms and health care worker hands. In some cases, the extent of patient-to-patient transmission has been found to be directly proportional to the level of environmental contamination. Improved cleaning/disinfection of environmental surfaces and hand hygiene have been shown to reduce the spread of all of these pathogens. Importantly, norovirus and C difficile are relatively resistant to the most common surface disinfectants and waterless alcohol-based antiseptics. Current hand hygiene guidelines and recommendations for surface cleaning/disinfection should be followed in managing outbreaks because of these emerging pathogens.

Abstract
Recent studies using direct covert observation or a fluorescent targeting method have consistently confirmed that most near patient surfaces are not being cleaned in accordance with existing hospital policies while other studies have confirmed that patients admitted to rooms previously occupied by patients with hospital pathogens have a substantially greater risk of acquiring the same pathogen than patients not occupying such rooms. These findings, in the context recent studies that have shown disinfection cleaning can be improved on average more than 100% over baseline, and that such improvement has been associated with a decrease in environmental contamination of high touch surfaces, support the benefit of decreasing environmental contamination of such surfaces. This review clarifies the differences between measuring cleanliness versus cleaning practices; describes and analyzes conventional and enhanced monitoring programs; addresses the critical aspects of evaluating disinfection hygiene in light of guidelines and standards; analyzes current hygienic practice monitoring tools; and recommends elements that should be included in an enhanced monitoring program.

Abstract
OBJECTIVE To determine the thoroughness of terminal disinfection and cleaning of patient rooms in hospital intensive care units and to assess the value of a structured intervention program to improve the quality of cleaning as a means of reducing environmental transmission of multidrug-resistant organisms within the intensive care unit. DESIGN Prospective, multicenter, and pre- and postinterventional study. SETTING Intensive care unit rooms in 27 acute care hospitals. Hospitals ranged in size from 25 beds to 709 beds (mean, 206 beds). INTERVENTIONS A fluorescent targeting method was used to objectively evaluate the thoroughness of terminal room cleaning before and after structured educational, procedural, and administrative interventions. Systematic covert monitoring was performed by infection control personnel to assure accuracy and lack of bias. MEASUREMENTS AND MAIN RESULTS In total, 3532 environmental surfaces (14 standardized objects) were assessed after terminal cleaning in 260 intensive care unit rooms. Only 49.5% (1748) of surfaces were cleaned at baseline (95% confidence interval, 42% to 57%). Thoroughness of cleaning at baseline did not correlate with hospital size, patient volume, case mix index, geographic location, or teaching status. After intervention and multiple cycles of objective performance feedback to environmental services staff, thoroughness of cleaning improved to 82% (95% confidence interval, 78% to 86%). CONCLUSIONS Significant improvements in intensive care unit room cleaning can be achieved in most hospitals by using a structured approach that incorporates a simple, highly objective surface targeting method and repeated performance feedback to environmental services personnel. Given the documented environmental transmission of a wide range of multidrug-resistant pathogens, our findings identify a substantial opportunity to enhance patient safety by improving the thoroughness of intensive care unit environmental hygiene.

Abstract
BACKGROUND Foams containing 62% ethanol are used for hand decontamination in many countries. A long drying time may reduce the compliance of healthcare workers in applying the recommended amount of foam. Therefore, we have investigated the correlation between the applied amount and drying time, and the bactericidal efficacy of ethanol foams. METHODS In a first part of tests, four foams (Alcare plus, Avagard Foam, Bode test foam, Purell Instant Hand Sanitizer) containing 62% ethanol, which is commonly used in U.S. hospitals, were applied to 14 volunteers in a total of seven variations, to measure drying times. In a second part of tests, the efficacy of the established amount of foam for a 30 s application time of two foams (Alcare plus, Purell Instant Hand Sanitizer) and water was compared to the EN 1500 standard of 2 x 3 mL applications of 2-propanol 60% (v/v), on hands artificially contaminated with Escherichia coli. Each application used a cross-over design against the reference alcohol with 15 volunteers. RESULTS The mean weight of the applied foam varied between 1.78 and 3.09 g, and the mean duration to dryness was between 37 s and 103 s. The correlation between the amount of foam applied and time until hands felt dry was highly significant (p < 0.001; Pearson's correlation coefficient: 0.724; 95% confidence interval: 0.52-0.93). By linear correlation, 1.6 g gave an intercept of a 30 s application time. Application of 1.6 g of Purell Instant Hand Sanitizer (mean log10-reduction: 3.05 +/- 0.45) and Alcare plus (3.58 +/- 0.71) was significantly less effective than the reference disinfection (4.83 +/- 0.89 and 4.60 +/- 0.59, respectively; p < 0.001). Application of 1.6 g of water gave a mean log10-reduction of 2.39 +/- 0.57. CONCLUSIONS When using 62% ethanol foams, the time required for dryness often exceeds the recommended 30 s. Therefore, only a small volume is likely to be applied in clinical practice. Small amounts, however, failed to meet the efficacy requirements of EN 1500 and were only somewhat more effective than water.

Abstract
Clostridium difficile infection (CDI) is a common problem encountered in solid organ transplant (SOT) recipients and the incidence is increasing. Generally, SOT recipients have an incidence of CDI that is similar to other post-operative patients, but this group has several unique risk factors that may contribute to more severe disease. Recent studies in non-transplant patients have indicated that treatment choices should be based on the severity of the illness. Although there continues to be a lack of well designed, randomized, controlled trials to support the management decisions that must be made for SOT recipients with CDI, the available evidence is reviewed and summarized for these treatment guidelines.

Abstract
Healthy infection prevention practices (HIPP) include hand hygiene, respiratory etiquette, environmental cleanliness, and use of personal protective equipment. These healthy practices are most used to protect individuals against exposure to bacterial and viral infections in the workplace, as well as in the home. Most often these infection prevention behaviors in critical care units are promoted to protect the patient from healthcare-associated infections. Yet, these practices are just as important to the health of the critical care nurse. Self-health in the workplace is essential to creating a healthy workplace environment, which is the goal of many intensive care units today. The benefits of creating a healthy work environment are improvement of patient/nurse satisfaction and nurse retention. HIPP reduce the risk of the critical care nurse's exposure to microbial pathogens such as methicillin-resistant Staphylococcus aureus and influenza. Pathogens that cause infections may contaminate the hands, the clothing, equipment, and blood, putting the nurse at risk for unhealthy hands, unhealthy flora, and unhealthy blood. The intensive care nurse is encouraged to embrace HIPP to nurture self, as well as protect the patient.

Abstract
Healthcare workers' hands are the most common vehicle for the transmission of healthcare-associated pathogens from patient to patient and within the healthcare environment. Hand hygiene is the leading measure for preventing the spread of antimicrobial resistance and reducing healthcare-associated infections (HCAIs), but healthcare worker compliance with optimal practices remains low in most settings. This paper reviews factors influencing hand hygiene compliance, the impact of hand hygiene promotion on healthcare-associated pathogen cross-transmission and infection rates, and challenging issues related to the universal adoption of alcohol-based hand rub as a critical system change for successful promotion. Available evidence highlights the fact that multimodal intervention strategies lead to improved hand hygiene and a reduction in HCAI. However, further research is needed to evaluate the relative efficacy of each strategy component and to identify the most successful interventions, particularly in settings with limited resources. The main objective of the First Global Patient Safety Challenge, launched by the World Health Organization (WHO), is to achieve an improvement in hand hygiene practices worldwide with the ultimate goal of promoting a strong patient safety culture. We also report considerations and solutions resulting from the implementation of the multimodal strategy proposed in the WHO Guidelines on Hand Hygiene in Health Care.

Abstract
OBJECTIVE The prevalence of serious infections caused by multidrug-resistant pathogens transmitted in the hospital setting has reached alarming levels, despite intensified interventions. In the context of mandates that hospitals ensure compliance with disinfection procedures of surfaces in the environment surrounding the patient, we implemented a multihospital project to both evaluate and improve current cleaning practices. DESIGN Prospective quasi-experimental, before-after, study. SETTING Thirty-six acute care hospitals in the United States ranging in size from 25 to 721 beds. METHODS We used a fluorescent targeting method to objectively evaluate the thoroughness of terminal room disinfection cleaning before and after structured educational and procedural interventions. RESULTS Of 20,646 standardized environmental surfaces (14 types of objects), only 9,910 (48%) were cleaned at baseline (95% confidence interval, 43.4-51.8). Thoroughness of cleaning at baseline correlated only with hospital expenditures for environmental services personnel (P = .02). After implementation of interventions and provision of objective performance feedback to the environmental services staff, it was determined that 7,287 (77%) of 9,464 standardized environmental surfaces were cleaned (P < .001). Improvement was unrelated to any demographic, fiscal, or staffing parameter but was related to the degree to which cleaning was suboptimal at baseline (P < .001). CONCLUSIONS Significant improvements in disinfection cleaning can be achieved in most hospitals, without a substantial added fiscal commitment, by the use of a structured approach that incorporates a simple, highly objective surface targeting method, repeated performance feedback to environmental services personnel, and administrative interventions. However, administrative leadership and institutional flexibility are necessary to achieve success, and sustainability requires an ongoing programmatic commitment from each institution.

Abstract
The use of hand rub to obtain maximum decrease in bacterial load is important because the reduction needed to avoid transmission is unknown. The monomer of 2-butanone peroxide is a peroxygen derivative with potential biocidal use in hospitals. The aim of this study was to compare the efficacy of hand rub with an alcoholic solution of peroxide 2-butanone versus five antiseptic products, against E. coli K12 (CECT 433) transient flora acquired by hand immersion in a broth culture following the UNE-EN-1500 standard. Isopropanol 60% (control) obtained 99.99% reductions, driving down the bacterial load from 10(6) cfu/mL in the initial inocula to <100 cfu/mL. Products A, B and C (different alcoholic solutions ranging from 65% to 75% with low amounts of biguanidines and/or quaternary ammonium compounds) resulted in significantly lower amounts, reducing initial inocula to approximately 500 cfu/mL. Products D and E (70-75% alcohol solutions containing higher amounts of different quaternary ammonium compounds and triclosan in the case of product E) produced reductions similar to that of isopropanol, with significantly larger reductions than products A, B and C. The product with the solution of 2-butanone peroxide produced the same effect as products D and E with mean reductions of approximately 4log(10) (99.99%), driving the initial inocula down to < or = 100 cfu/mL, despite the low concentration (35%) of propanol in the solution. This novel peroxygen biocide offers high in-vivo cidal activity against acquired E. coli transient flora, offering an alternative to products with higher alcohol concentrations.

Abstract
BACKGROUND The growing burden of neonatal mortality associated with hospital-acquired neonatal sepsis in the developing world creates an urgent need for cost-effective infection-control measures in resource-limited settings. METHODS Using a before-and-after comparison design, we measured how rates of staff hand-hygiene compliance, colonization with drug-resistant pathogens (defined as ceftazidime- and/or gentamicin-resistant gram-negative bacilli and drug-resistant gram-positive cocci), bacteremia, and overall mortality changed after the introduction of a simplified package of infection-control measures at 2 neonatal intensive care units (NICUs) in Manila, The Philippines. RESULTS Of all 1827 neonates admitted to the NICU, 561 (30.7%) arrived from delivery already colonized with drug-resistant bacteria. Of the 1266 neonates who were not already colonized, 578 (45.6%) became newly colonized with drug-resistant bacteria. Of all 1827 neonates, 358 (19.6%) became bacteremic (78.2% were infected with gram-negative bacilli) and 615 (33.7%) died. Of 2903 identified drug-resistant colonizing bacteria, 85% were drug-resistant gram-negative bacilli (predominantly Klebsiella species, Pseudomonas species, and Acinetobacter species) and 14% were methicillin-resistant Staphylococcus aureus. Contrasting the control period with the intervention period at each NICU revealed that staff hand-hygiene compliance improved (NICU 1: relative risk, 1.3; 95% confidence interval 1.1-1.5; NICU 2: relative risk, 1.6; 95% confidence interval, 1.4-2.0) and that overall mortality decreased (NICU 1: relative risk, 0.5; 95% confidence interval, 0.4-0.6; NICU 2: relative risk, 0.8; 95% confidence interval, 0.7-0.9). However, rates of colonization with drug-resistant pathogens and of sepsis did not change significantly at either NICU. DISCUSSION Nosocomial transmission of drug-resistant pathogens was intense at these 2 NICUs in The Philippines; transmission involved mostly drug-resistant gram-negative bacilli. Infection-control interventions are feasible and are possibly effective in resource-limited hospital settings.

Abstract
OVERVIEW It has long been known that hand hygiene among health care workers plays a central role in preventing the transmission of infectious agents. But despite a Joint Commission requirement that Centers for Disease Control and Prevention hand hygiene guidelines be implemented in hospitals, compliance among health care workers remains low. The authors argue that hospitals may best improve compliance by assessing the barriers to it, measuring the rates of compliance, educating staff on the importance of hand hygiene, making sanitizing products more available for staff use, and holding staff accountable. The authors emphasize as well that lasting improvement in hand hygiene is a collaborative effort that depends on the committed support of hospital administrators.

Abstract
Hospital-acquired (nosocomial) infections (HAIs) increase morbidity, mortality and medical costs. In the USA alone, nosocomial infections cause about 1.7 million infections and 99 000 deaths per year. HAIs are spread by numerous routes including surfaces (especially hands), air, water, intravenous routes, oral routes and through surgery. Interventions such as proper hand and surface cleaning, better nutrition, sufficient numbers of nurses, better ventilator management, use of coated urinary and central venous catheters and use of high-efficiency particulate air (HEPA) filters have all been associated with significantly lower nosocomial infection rates. Multiple infection control techniques and strategies simultaneously ('bundling') may offer the best opportunity to reduce the morbidity and mortality toll of HAIs. Most of these infection control strategies will more than pay for themselves by saving the medical costs associated with nosocomial infections. Many non-pharmacological interventions to prevent many HAIs will also reduce the need for long or multiple-drug antibiotic courses for patients. Lower antibiotic drug usage will reduce risk of antibiotic-resistant organisms and should improve efficacy of antibiotics given to patients who do acquire infections.
