Abstract
This article aims to evaluate the evidence relating to the effectiveness of alcohol-based gel for hand sanitising, or 'handrub', in infection control in healthcare settings with particular reference to renal nursing, as this has become pertinent due to the increasing reliance on evidence-based practice. There is a need to implement better infection control strategies and education, to reinforce knowledge among the public, health professionals and those at high risk of infection not only in renal nursing, but also in other areas of practice. Healthcare-associated infections (HCAIs) put patients' safety at risk, increase morbidity and mortality, extend the length of hospital admission and increase the cost to the NHS. There is evidence that the prevalence of HCAIs in England can be minimised through the use of different infection control measures. For example, alcohol-based handrub has been found to be associated with minimising the spread of gastrointestinal infections not only in hospital settings, but also in childcare centres. In addition, the UK national guidelines recommend regular handwashing (implementing the right technique) when hands are visibly dirty and hand disinfection with alcohol-based handrub when they are not visibly dirty. This should be before, in between and after different healthcare activities are performed.

Abstract
Proper performance of hand hygiene at key moments during patient care is the most important means of preventing health care-associated infections (HAIs). With increasing awareness of the cost and societal impact caused by HAIs has come the realization that hand hygiene improvement initiatives are crucial to reducing the burden of HAIs. Multimodal strategies have emerged as the best approach to improving hand hygiene compliance. These strategies use a variety of intervention components intended to address obstacles to complying with good hand hygiene practices, and to reinforce behavioral change. Although research has substantiated the effectiveness of the multimodal design, challenges remain in promoting widespread adoption and implementation of a coordinated approach. This article reviews elements of a multimodal approach to improve hand hygiene and advocates the use of a "bundled" strategy. Eight key components of this bundle are proposed as a cohesive program to enable the deployment of synergistic, coordinated efforts to promote good hand hygiene practice. A consistent, bundled methodology implemented at multiple study centers would standardize processes and allow comparison of outcomes, validation of the methodology, and benchmarking. Most important, a bundled approach can lead to sustained infection reduction.

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
BACKGROUND Clostridium difficile-associated diarrhea is a leading cause of hospital-acquired diarrhea. We sought to determine whether the institution of a hospital-wide alcohol-based hand rub (ABHR) policy was associated with an increase in the incidence and/or severity of health care facility-onset, health care facility-associated C difficile diarrhea (CDAD). METHODS We used a retrospective chart review analysis to compare incidence rates of CDAD before and after implementation of the ABHR policy. We also compared rates of sepsis, colectomy, and death in patients with CDAD before and after implementation of the ABHR policy. RESULTS The incidence rate of CDAD was 3.98 per 10,000 patient-days after implementation of the ABHR policy, compared with 4.96 per 10,000 patient-days before implementation (P = .0036). The crude mortality rate in patients diagnosed with CDAD was 10.7% after implementation, compared with 13.3% before implementation (P = .275). The rate of sepsis in patients diagnosed with CDAD was 19.6% after implementation, compared with 5.2% before implementation (P < .0001). CONCLUSION Our data provide no evidence of an increased CDAD rate after implementation of an ABHR policy at our institution. The rate of sepsis in patients diagnosed with CDAD did rise, indicating increased severity of illness in patients with C difficile infection.

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
OBJECTIVE To evaluate common hand hygiene methods for efficacy in removing Clostridium difficile. DESIGN Randomized crossover comparison among 10 volunteers with hands experimentally contaminated by nontoxigenic C. difficile. METHODS Interventions included warm water with plain soap, cold water with plain soap, warm water with antibacterial soap, antiseptic hand wipes, alcohol-based handrub, and a control involving no intervention. All interventions were evaluated for mean reduction in colony-forming units (CFUs) under 2 contamination protocols: "whole hand" and "palmar surface." Results were analyzed according to a Bayesian approach, by using hierarchical models adjusted for multiple observations. RESULTS Under the whole-hand protocol, the greatest adjusted mean reductions were achieved by warm water with plain soap (2.14 log(10) CFU/mL [95% credible interval (CrI), 1.74-2.54 log(10) CFU/mL]), cold water with plain soap (1.88 log(10) CFU/mL [95% CrI, 1.48-2.28 log(10) CFU/mL), and warm water with antibacterial soap (1.51 log(10) CFU/mL [95% CrI, 1.12-1.91 log(10) CFU/mL]), followed by antiseptic hand wipes (0.57 log(10) CFU/mL [95% CrI, 0.17-0.96 log(10) CFU/mL]). Alcohol-based handrub (0.06 log(10) CFU/mL [95% CrI, -0.34 to 0.45 log(10) CFU/mL]) was equivalent to no intervention. Under the palmar surface protocol, warm water with plain soap, cold water with plain soap, and warm water with antibacterial soap again yielded the greatest mean reductions, followed by antiseptic hand wipes (26.6, 26.6, 26.6, and 21.9 CFUs per plate, respectively), when compared with alcohol-based handrub. Hypothenar (odds ratio, 10.98 [95% CrI, 1.96-37.65]) and thenar (odds ratio, 6.99 [95% CrI, 1.25-23.41]) surfaces were more likely than fingertips to remain heavily contaminated after handwashing. CONCLUSIONS Handwashing with soap and water showed the greatest efficacy in removing C. difficile and should be performed preferentially over the use of alcohol-based handrubs when contact with C. difficile is suspected or likely.

Abstract
BACKGROUND An association between use of hand hygiene products and health care-associated infection rates was investigated in a large Norwegian university hospital. METHODS We conducted an ecologic study by combining data from purchasing and admission systems with data from 32 point prevalence surveys (27,248 patients) in 1998-2005. Data on purchase of hand disinfectants and soap, and patient-days, were collected for 20 bed wards similar to those of the prevalence surveys. RESULTS The prevalence of infections was 7.1%. We found no significant decline in overall infections (P = .19), but use of hand hygiene products significantly increased from 28.5 L per 1000 patients-days in 1998 to 43.3 L per 1000 patient-days in 2005 (P < .001). After examining a linear dose-response relation between use and infection rates, we observed a borderline significant decline in infections from 8% to 6% with increased use of hand hygiene products (P = .05). This association appeared stronger for wards that were registered with infections >9% at study start in 1998 (P < .001). CONCLUSION These data suggests that infection rates may be reflected by amount of hand hygiene products used. Quantification of such products over time may serve as an indicator for hand hygiene performance in hospitals.

Abstract
We examined the incidence of infection with methicillin-resistant Staphylococcus aureus (MRSA) in patients admitted to the Leicester Royal Infirmary Trauma Unit between January 2004 and June 2006. The influence of MRSA status at the time of their admission was examined, together with age, gender and diagnosis, using multi-variant analysis. Of 2473 patients, 79 (3.2%) were MRSA carriers at the time of admission and 2394 (96.8%) were MRSA-negative. Those carrying MRSA at the time of admission were more likely to develop surgical site infection with MRSA (7 of 79 patients, 8.8%) than non-MRSA carriers (54 of 2394 patients, 2.2%, p < 0.001). Further analysis showed that hip fracture and increasing age were also risk factors with a linear increase in relative risk of 1.8% per year. MRSA carriage at admission, age and the pathology are all associated with an increased rate of developing MRSA wound infection. Identification of such risk factors at admission helps to target health-care resources, such the use of glycopeptide antibiotics at induction and the ‘building-in’ of increased vigilance for wound infection pre-operatively.

Abstract
BACKGROUND Nurses have a high risk of developing hand eczema due to hand disinfection procedures. OBJECTIVES To investigate the perception of nurses regarding the adverse effects of hand washing (HW) and alcoholic disinfection (ADI), and to obtain data on the prevalence of hand dermatitis and sensitization to alcohols and alcohol-based hand rubs (ABHRs). METHODS A self-administered questionnaire survey, carried out as a pilot study (PS), followed by a modified multicentre study (MC) in five hospitals. Patch tests to ethanol (80%), 1-propanol (60%), 2-propanol (70%) and ABHRs were performed in a subsample. RESULTS The majority (PS 60.1%; MC 69.5%) of nurses considered ADI to be more damaging than HW. Mostly, ADI and HW were suspected to have irritant effects (ADI 79.2%/52.1%; HW 65.5%/36.2%) compared with an allergenic potential (ADI 10.4%/5.8%; HW 7.8%/3.9%). The prevalence of hand dermatitis in the MC was 13.4% by self-diagnosis and 22.4% by symptom-based questions. In 50 tested individuals no sensitization and only two irritant reactions to alcohols and three single-positive reactions to ABHRs were observed, none of the latter related to alcohols. CONCLUSIONS Although ADI is known to cause less skin irritation than HW, nurses perceive ADI as more damaging, resulting in: (i) a low compliance with ADI and (ii) a higher prevalence of hand dermatitis because the more deleterious HW is preferred. This may result in an increase in occupational disease and nosocomial infections. Educational programmes should promote ADI as a procedure with good efficiency and skin tolerability to reduce the prevalence of hand eczema in nurses and to enhance compliance with hand hygiene standards.

Abstract
BACKGROUND The objectives of this integrative review were to critically examine the overall state of the current evidence on the relationship between hand hygiene interventions and the incidence of health care-associated infections (HCAIs) in acute care and long-term care settings, and offer recommendations for future directions in the field based on our findings. METHODS We searched for original research and reviews of research published between January 1, 1996, and July 31, 2006. Studies were identified through the electronic databases Medline, CINAHL, EMBASE, PUBMED, the Cochrane Library, and through expert consultation. Our comprehensive search strategy included all English articles for which hand hygiene or handwashing-related terms were combined with HCAIs. All studies that investigated a relationship between hand hygiene practices and HCAIs in acute care facilities were considered. These hand hygiene practices included the initiation of multimodal hand hygiene initiatives, the introduction of alcohol sanitizers, the implementation or changes of the infection control practices or infection control policies, and other organizational interventions. Studies only examining hand hygiene compliance, efficacy of alcohol hand gels, plain soap, and antimicrobial soap in reducing bacteria count recovered from hands were excluded. RESULTS Of the 1120 articles retrieved, 35 publications, including 4 reviews of research discussed at the outset of this article, met our inclusion criteria. The remaining 31 eligible original studies included 18 (58.07%) before and after studies without control groups, 4 (12.90%) before and after studies with a control group, 3 (9.68%) cohort studies with no control group, 4 (12.90%) cohort studies with a control group, and 2 (6.45%) randomized trials. Over 50% (16 or 31) of the studies were conducted in the U.S. Two independent reviewers conducted independent evaluations of all eligible studies, critiquing and scoring each study using a rating scale for examining the fatal flaws of quasi-experimental and before and after studies. CONCLUSIONS There is a lack of rigorous evidence linking specific hand hygiene interventions with the prevention of HCAIs. The varied nature of the interventions used and the diverse factors affecting the acquisition of HCAIs make it difficult to show the specific effect of hand hygiene alone. The most frequent methodologies currently used in this research area are before and after observational studies without a control comparison group. Based on these findings, we recommend that researchers used a modified version of Larson's 2005 criteria to guide the design and conduct of future before and after observational studies in this area. We also argue that as we accumulate stronger evidence of which interventions are most effective, we need to develop additional research approaches to study how organizations succeed and fail in fostering the uptake of evidence-based hand hygiene interventions.

Abstract
Reducing the incidence of healthcare-associated infection represents a major challenge. This systematic review of the evidence base considers the clinical effectiveness of incorporating an alcohol-based hand hygiene product into procedures aimed at improving compliance with hand hygiene guidelines, and thereby reducing the incidence of healthcare-associated infections. Multi-component interventions that included alcohol-based products were as effective as those that did not, both in achieving sustained hand hygiene compliance and in reducing infection rates. However, a number of difficulties were encountered in assessing hand hygiene studies: the problem of attributing efficacy to an alcohol-based product when used in a multi-component intervention; the variability inherent in the design of such studies; and how to use data from uncontrolled, unblinded studies in the assessment.

Abstract
Peritoneal dialysis (PD) related infections continue to be a serious complication for PD patients. Peritonitis can be associated with pain, hospitalization and catheter loss as well as a risk of death. Peritonitis risk is not evenly spread across the PD population or programs. Very low rates of peritonitis in a program are possible if close attention is paid to the causes of peritonitis and protocols implemented to reduce the risk of infection. Protocols to decrease infection risk in PD patients include proper catheter placement, exit-site care that includes Staphylococcus aureus prophylaxis, careful training of patients with periodic retraining, treatment of contamination, and prevention of procedure-related and fungal peritonitis. Extensive data have been published on the use of antibiotic prophylaxis to prevent exit site infections. There are fewer data on training methods of patients to prevent infection risk. Quality improvement programs with continuous monitoring of infections, both of the catheter exit site and peritonitis, are important to decrease the PD related infections in PD programs. Continuous review of every episode of infection to determine the root cause of the event should be routine in PD programs. Further research is needed examining approaches to decrease infection risk.

Abstract
Compliance with hand hygiene is widely recognized as the most important factor in preventing transmission of infection to patients in health care settings. However, there is no standardized method for measuring compliance. The three major methods used are direct observation, self-report and indirect measurement of hand hygiene product usage. This review discusses the methods of compliance monitoring and the advantages and drawbacks of each.

Abstract
BACKGROUND Clostridium difficile-associated diarrhea (CDAD) is a potentially preventable and often troublesome gastrointestinal complication after cardiac surgery. METHODS A retrospective study was performed of 8,405 cardiac surgery patients at two institutions between January 1997 and August 2004. Preoperative cardiac risk factors, perioperative factors including blood product transfusion, antibiotic utilization, and postoperative morbidity and mortality were recorded. Univariate and multivariate analyses were performed comparing C. difficile patients with a control group matched by date of surgery and institution. RESULTS Sixty-six of the 8,405 patients identified with toxin-positive CDAD produced an overall incidence of 0.79% (0.70% at institution A and 1.09% at institution B), with a peak overall incidence of 5.45% in June 2003. Independent prognostic factors for CDAD by multivariate analysis included advancing age (odds ratio [OR] 1.028, 95% confidence interval [CI]: 1.001 to 1.056; p = 0.034), female sex (OR 2.026, 95% CI: 1.102 to 3.722; p = 0.022), blood product transfusion (OR 3.277, 95% CI: 1.292 to 8.311; p = 0.006), and increasing cumulative days of antibiotic administration (OR 1.046, 95% CI: 1.014 to 1.080; p = 0.004). There were no differences in the proportion of fluoroquinolones, cephalosporins, or penicillin derivatives administered between groups. The diagnosis of CDAD was associated with a greater median length of mechanical ventilation (25 hours versus 12 hours, p < 0.001), longer intensive care unit stay (5 days versus 2 days, p < 0.001), and extended hospital stay (21 days versus 7 days, p < 0.001), with no difference in 30-day mortality (7.6% versus 9.5%, p = 0.80). CONCLUSIONS Although the overall incidence of CDAD was low, alteration in transfusion practices and antibiotic utilization may impact the development of CDAD among cardiac surgical patients.

Abstract
Handwashing is considered to be the most effective way of reducing cross-infection. Rates of healthcare-associated infection and the incidence of meticillin-resistant Staphylococcus aureus are higher in the UK than in many other European countries. The government has responded by introducing the 'CleanYourHandsCampaign' throughout England and Wales, based on the success of the approach employed in Geneva. Alcohol hand rub is placed at every bedside in acute hospitals, ward housekeepers should replenish supplies and feedback on compliance is provided to health workers. Posters and other promotional materials are used to remind health workers and visitors to use the hand rub. Patients are encouraged to ask health workers if they have cleaned their hands before contact. In this paper we argue that the evidence base underpinning the CleanYourHandsCampaign is incomplete. Alcohol hand rub is acknowledged as a useful adjunct to hand hygiene but it is not effective in all circumstances. There is some evidence to support the use of feedback on performance to encourage compliance but no evidence that promotional materials such as posters or patient reminders are effective. The ethics of encouraging hospital patients to take responsibility for their own safety is questioned. Much of the success in Geneva must be attributed to the attention given to contextual factors within the organization that encouraged hand rub use, especially hospital-wide 'ownership' of the initiative by managers and senior health professionals. A customized intervention from another country that fails to consider local organizational factors likely to influence the implementation of the campaign is unlikely to be effective. It is concluded that although hand hygiene is of undoubted importance, undue emphasis should not be placed on it as a 'quick fix' to solve the unacceptably high rates of healthcare-associated infection in National Health Service hospitals.

Abstract
BACKGROUND In October 2004, The World Health Organization (WHO) launched the World Alliance for Patient Safety. Within the alliance, the first priority of the Global Patient Safety Challenge is to reduce health care-associated infection. A key action within the challenge is to promote hand hygiene in health care globally as well as at the country level through the campaign "Clean Care is Safer Care." As a result, the WHO is developing Guidelines on Hand Hygiene in Health Care, designed to be applicable throughout the world. METHODS This paper summarizes one component of the global WHO guidelines related to the impact of hand hygiene on the skin of health care personnel, including a discussion of types of skin reactions associated with hand hygiene, methods to reduce adverse reactions, and factors to consider when selecting hand hygiene products. RESULTS Health care professionals have a higher prevalence of skin irritation than seen in the general population because of the necessity for frequent hand hygiene during patient care. CONCLUSION Ways to minimize adverse effects of hand hygiene include selecting less irritating products, using skin moisturizers, and modifying certain hand hygiene practices such as unnecessary washing. Institutions need to consider several factors when selecting hand hygiene products: dermal tolerance and aesthetic preferences of users as well as practical considerations such as convenience, storage, and costs.

Abstract
A formerly infrequently isolated strain of Clostridium difficile known as BI/NAP1 has resulted in geographically diverse outbreaks of C. difficile-associated disease. Such rapid dissemination and distribution of an outbreak strain of C. difficile are unprecedented, with many regions across North America, as well as several countries in Europe, being affected, all in such a short period of time. Also of note is that nontraditional hosts (e.g., otherwise healthy, noninstitutionalized persons residing in the community, some without antimicrobial exposure) have been reported to have severe disease. Data suggest that certain virulence characteristics may be responsible for more severe clinical presentations and poor outcomes. These factors (e.g., hypertoxin production, hypersporulation, antimicrobial resistance) possessed by a previously uncommon strain of C. difficile, in conjunction with particular host and environmental factors, may have precipitated the now widespread establishment of this pathogen. Antimicrobial intervention has traditionally been a mainstay of combating C. difficile-associated disease. Efforts to combat BI/NAP1 should include good antimicrobial stewardship in addition to effective infection control and environmental intervention.

Abstract
• Background Adherence to hand hygiene standards is poor. Approaches and systems to improve hand hygiene practices warrant testing.
• Objective To compare the frequency of use of manually operated and touch-free dispensers of sanitizer for hand hygiene.
• Methods Manual and touch-free dispensers of alcohol sanitizer were placed in the emergency department and an intensive care unit of a large pediatric hospital for two 2-month periods for each type of dispenser. Counting devices installed in each dispenser and direct observations were used to determine actual frequency of and indications for hand hygiene.
• Results The touch-free dispensers were used significantly more often than were the manual dispensers. The means for the number of episodes of hand hygiene per hour were 4.42 for the touch-free dispensers and 3.33 for the manual dispensers (P = .04); the means for the number of episodes per patient per hour were 2.22 and 1.79, respectively (P = .004); and the means for the number of uses of the dispenser per day were 41.2 and 25.6, respectively (P = .02). However, the overall compliance rate was 38.4% (2136 episodes of hand hygiene per 5568 indications for hand hygiene).
• Conclusions The type of dispensing system influenced hand hygiene behavior. Nevertheless, overall hand hygiene compliance remained low. In order for interventions to have a major effect on hand hygiene, multiple factors must be considered.

Abstract
This review gives an overview of hand hygiene in healthcare and in the community, including some aspects which have attracted little attention, such as hand drying and cultural issues determining hand hygiene behaviour. Hand hygiene is the most effective measure for interrupting the transmission of microorganisms which cause infection both in the community and in the healthcare setting. Using hand hygiene as a sole measure to reduce infection is unlikely to be successful when other factors in infection control, such as environmental hygiene, crowding, staffing levels and education are inadequate. Hand hygiene must be part of an integrated approach to infection control. Compliance with hand hygiene recommendations is poor worldwide. While the techniques involved in hand hygiene are simple, the complex interdependence of factors which determine hand hygiene behaviour makes the study of hand hygiene complex. It is now recognised that improving compliance with hand hygiene recommendations depends on altering human behaviour. Input from behavioural and social sciences is essential when designing studies to investigate compliance. Interventions to increase compliance with hand hygiene practices must be appropriate for different cultural and social needs. New strategies to promote hand hygiene worldwide include the formation of public-private partnerships.
