Abstract
BACKGROUND Infection prevention and control (IPC) practices vary among companion animal clinics, and outbreaks with carbapenemase-producing Enterobacterales (CPE) have been described. AIM To investigate the effect of an IPC intervention (introduction of IPC protocols, IPC lectures, hand hygiene campaign) in four companion animal clinics. METHODS IPC practices, environmental and hand contamination with antimicrobial-resistant micro-organisms (ARM) and hand hygiene (HH) were assessed at baseline, and 1 and 5 months after the intervention. RESULTS Median IPC scores (% maximum score) improved from 57.8% (range 48.0-59.8%) to 82.9% (range 81.4-86.3%) at 1-month follow-up. Median cleaning frequency assessed by fluorescent tagging increased from 16.7% (range 8.9-18.9%) to 30.6% (range 27.8-52.2%) at 1-month follow-up and 32.8% (range 32.2-33.3%) at 5-month follow-up. ARM contamination was low in three clinics at baseline and undetectable after the intervention. One clinic showed extensive contamination with ARM including CPE before and after the intervention (7.5-16.0% ARM-positive samples and 5.0-11.5% CPE-positive samples). Mean HH compliance improved from 20.9% [95% confidence interval (CI) 19.2-22.8%] to 42.5% (95% CI 40.4-44.7%) at 1-month follow-up and 38.7% (95% CI 35.7-41.7%) at 5-month follow-up. Compliance was lowest in the pre-operative preparation area at baseline (11.8%, 95% CI 9.3-14.8%) and in the intensive care unit after the intervention (28.8%, 95% CI 23.3-35.1%). HH compliance was similar in veterinarians (21.5%, 95% CI 19.0-24.3%) and nurses (20.2%, 95% CI 17.9-22.7%) at baseline, but was higher in veterinarians (46.0%, 95% CI 42.9-49.1%) than nurses (39.0%, 95% CI 36.0-42.1%) at 1-month follow-up. CONCLUSION The IPC intervention improved IPC scores, cleaning frequency and HH compliance in all clinics. Adapted approaches may be needed in outbreak situations.

Abstract
Background Patients sometimes contract healthcare associated infections (HCAI) which are unrelated to their primary reasons for hospital admission. Surgical site infections are the most investigated and most recurrent type of HCAI in developing countries, affecting up to one-third of surgical patients. Objective This study aimed to assess and offer context to the hand hygiene resources available in a Nigerian teaching hospital through ward infrastructure survey, and to determine the hand hygiene compliance rate among surgical healthcare workers (HCWs) in a Nigerian teaching hospital through hand hygiene observations. Methods Ward infrastructure survey was conducted in the two adult surgical wards of the hospital using the World Health Organisation (WHO) hand hygiene ward infrastructure survey form. Hand hygiene observations were monitored over seven days in the surgical wards using a modified WHO hand hygiene observation form. Results Hand hygiene resources were insufficient, below the WHO recommended minimum standards. Seven hundred hand hygiene opportunities were captured. Using SPSS version 24.0, we conducted a descriptive analysis of audit results, and results were presented according to professional group, seniority and hand hygiene opportunities of the participants. Overall hand hygiene compliance was 29.1% and compliance was less than 40% across the three professional groups of doctors, nurses and healthcare assistants. Conclusion Hand hygiene compliance rates of the surgical HCWs are comparable to those in other Sub-Saharan African countries as well as in developed countries.

Abstract
Background: Hand hygiene (HH) is one of the most important measures to prevent healthcare‐associated infections. Data on HH compliance in companion animal veterinary institutions in Europe are sparse. Methods: This observational study assessed HH according to WHO standards in three large and two medium‐sized clinics and two primary care practices in Switzerland. Associations with HH indication, professional group, clinical area and institution were determined using a generalized linear mixed effects model. Results: Based on 2056 observations, overall HH compliance [95% confidence interval] was 32% [30%‐34%]. HH compliance was highest in the consultation area (41% [38%‐45%]) and after contact to body fluids (45% [40%‐50%]), and lowest in the pre‐OR area (20% [15%‐24%]) and before clean/aseptic procedures (12% [9%‐15%]). Veterinarians showed a higher HH compliance (37% [34%‐40%]) than veterinary nurses (25% [22%‐28%]). HH compliance was lower before clean/aseptic procedures compared to all other indications (all p < 0.015 except ‘before touching a patient’ in medium‐sized clinics/practices, p = 0.095) and higher in the consultation area compared to all other areas in large clinics (all p < 0.04). Conclusion: Effective HH training should urgently be promoted for all veterinary personnel with special emphasis on the importance of HH before clean/aseptic procedures.

Abstract
Poor hand hygiene in hospital settings leads to the spread of communicable disease to a population of individuals already medically compromised. The current study used the Performance Diagnostic Checklist-Human Services to develop an intervention targeting hand hygiene compliance for nine participants employed by an inpatient unit. The use of performance feedback and goal setting improved hand hygiene compliance when compared to baseline for eight of nine participants. Results are discussed in terms of strategies for using performance analysis to identify effective interventions to address performance deficits.

Sands M, Aiken AM, Cumming O, Aunger R. The effect of behavioural interventions targeting hand hygiene practices among nurses in high-income hospital settings: a systematic review. Public Health Rev 2020; 41:29. [PMID: 33372645 PMCID: PMC7720577 DOI: 10.1186/s40985-020-00141-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Accepted: 11/04/2020] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Hand hygiene is a critical behaviour for infection control but efforts to raise compliance among clinical professionals have been met with mixed success. The aim of this systematic review was to identify the effectiveness of the behaviour change techniques utilised in recent hand hygiene interventions that seek to improve hand hygiene compliance among nurses in hospitals in high-income countries. Nurses are at the frontline of healthcare delivery, and so improving their HH behaviour and thus increasing HHC rates will have a relatively large impact on reducing transmission and preventing healthcare acquired infections. METHODS High-quality studies among nurses in high-income countries were surveyed from the scientific literature, following PRISMA guidelines, to identify which kinds of behaviour change mechanisms have been used to effectively increase hand hygiene compliance. Only seven studies met all inclusion criteria. A formal meta-analysis was not conducted due to the heterogeneity of the included studies. Instead, the review analysed studies in line with the Intervention Component Analysis approach to identify which differences in intervention characteristics appear to be important. Analysis proceeded in two steps: first, the Effective Practice and Organization of Care Data Extraction Checklist was used to identify the study design and to describe the intervention, target population, setting, results, outcome measures, and analytic approach. The second step involved inferring the behavioural change techniques used in the complex study interventions. Following coding, logic models were then inferred for each study to identify the Theory of Change behind each intervention. These Theories of Change were then examined for suggestions as to which BCTs were likely to have been responsible for any effectiveness observed. RESULTS Goals and planning (to achieve specific ends), comparison of behaviour (to peers or some ideal) and feedback and monitoring (observing and providing feedback about behaviour or outcomes) were the most frequently used behaviour change technique groupings used across studies and within interventions. CONCLUSION The complexity of the interventions used and lack of sufficient studies makes assignment of responsibility for behaviour change to specific behaviour change techniques difficult. Delivery channels and activities identified in the study Theories of Change were also highly individualized and so difficult to compare. However, we identified a temporal shift in types of techniques used in these recent studies on HH interventions, as compared with studies from prior to the review period. These newer interventions did not focus on providing access to alcohol-based hand rub or trying to solely encourage administrative support. Instead, they had nurses create goals and plan how to best facilitate HH, compared both individuals' and the group's behaviour to others, and focused on providing feedback.

Abstract
Coronavirus disease 2019 (COVID-19) was an impetus for a multitude of transformations – from the ever-changing clinical practice frameworks, to changes in our execution of education and research. It called for our decisiveness, innovativeness, creativity, and adaptability in many circumstances. Even as care for our patients was always top priority, we tried to integrate, where possible, educational and research activities in order to ensure these areas continue to be harnessed and developed. COVID-19 provided a platform that stretched our ingenuity in all these domains. One of the mnemonics we use at SingHealth in responding to crisis is PACERS: P: Preparedness (in responding to any crisis, this is critical) A: Adaptability (needed especially with the ever-changing situation) C: Communications (the cornerstone in handling any crisis) E: Education (must continue, irrespective of what) R: Research (new opportunities to share and learn) S: Support (both physical and psychological). This article shares our experience integrating the concept of simulation-based training, quality improvement, and failure mode analysis.

Analysis of Gender-Dependent Personal Protective Behaviors in a National Sample: Polish Adolescents' COVID-19 Experience (PLACE-19) Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17165770. [PMID: 32785004 PMCID: PMC7459707 DOI: 10.3390/ijerph17165770] [Citation(s) in RCA: 57] [Impact Index Per Article: 14.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Revised: 08/04/2020] [Accepted: 08/06/2020] [Indexed: 12/26/2022]
Abstract
During the coronavirus-19 disease (COVID-19) pandemic, the basic strategy that is recommended to reduce the spread of the disease is to practice proper hand hygiene and personal protective behaviors, but among adolescents, low adherence is common. The present study aimed to assess the gender-dependent hand hygiene and personal protective behaviors in a national sample of Polish adolescents. The Polish Adolescents’ COVID-19 Experience (PLACE-19) Study was conducted in a group of 2323 secondary school students (814 males, 1509 females). Schools were chosen based on the random quota sampling procedure. The participants were surveyed to assess their knowledge and beliefs associated with hand hygiene and personal protection, as well as their actual behaviors during the COVID-19 pandemic. The majority of respondents gave proper answers when asked about their knowledge. However, females displayed a higher level of knowledge (p < 0.05). Most of the respondents declared not leaving home, handwashing, using alcohol-based hand rub, avoiding contact with those who may be sick, and avoiding public places as their personal protective behaviors. They declared using face masks and gloves after the legal regulation requiring people to cover their nose and mouth in public places was enacted in Poland. Regarding the use of face masks and not touching the face, no gender-dependent differences were observed, while for all the other behaviors, females declared more adherence than males (p < 0.05). Females also declared a higher daily frequency of handwashing (p < 0.0001) and washing their hands always when necessary more often than males (68.2% vs. 54.1%; p < 0.0001). Males more often indicated various reasons for not handwashing, including that there is no need to do it, they do not feel like doing it, they have no time to do it, or they forget about it (p < 0.0001), while females pointed out side effects (e.g., skin problems) as the reason (p = 0.0278). Females more often declared handwashing in circumstances associated with socializing, being exposed to contact with other people and health (p < 0.05), and declared always including the recommended steps in their handwashing procedure (p < 0.05). The results showed that female secondary school students exhibited a higher level of knowledge on hand hygiene and personal protection, as well as better behaviors, compared to males. However, irrespective of gender, some false beliefs and improper behaviors were observed, which suggests that education is necessary, especially in the period of the COVID-19 pandemic.

Abstract
Introduction Hand hygiene is crucial to prevent cross infection. Healthcare students are in a prime position to learn hand hygiene skills. The aim of this study was to analyze hand hygiene behavioral intentions of healthcare students before and after contact with the patient and to compare the knowledge of and attitude towards hand hygiene between medical and nursing students. Methods In a descriptive survey research design, convenience selection of a sample of medical students (n=657) and nursing students (n=303) was done from modules taught by the Department of Preventive Medicine and Public Health in both Medicine and Nursing undergraduate degrees in four Spanish universities. The hand hygiene Questionnaire, a validated instrument to evaluate behavior, knowledge, and attitudes, was used. Results A significantly lower percentage of students reported always or almost always carrying out hand hygiene before contact with the patient or invasive procedures in comparison to the percentage complying after contact with secretions or with the patient. Although hand hygiene knowledge appears acceptable, its importance is not sufficiently valued. Conclusions There are deficiencies in behavioral intention, knowledge, and attitudes related to hand hygiene in medical and nursing students. Better results are observed among nursing students, especially those who have received specific training.

Abstract
The outbreak of severe acute respiratory syndrome (SARS) claimed the lives of 286 Hong Kong people in 2003. Since then, the Hong Kong government has been promoting the benefits of proper hand hygiene. There are few studies that explore the general quality of handwashing and the hand-hygiene practices of the public of Hong Kong; given this, the aim of this study is to explore this neglected topic. This study is a quantitative study that was conducted in January 2018. The results show that the majority of participants only wash their hands after using the toilet (87%) or handling vomitus or faecal matter (91%). The mean duration of handwashing was 36.54 seconds (SD = 18.57). The areas of the hand most neglected during handwashing were the fingertips (48.1%), medial area (30.5%), and back of the hand (28%). A multiple logistic regression shows that participants who have reached third-level education or higher often tend to be more hand hygienic than those who have not reached third-level education (p ≤ 0.001, B = 1.003). Thus, participants aged 30 and above tend to neglect 5 more areas of the hand than those aged below 30 (p=0.001, B = 4.933).

The politics and ethics of hospital infection prevention and control: a qualitative case study of senior clinicians' perceptions of professional and cultural factors that influence doctors' attitudes and practices in a large Australian hospital.

Abstract
BACKGROUND Hospital infection prevention and control (IPC) programs are designed to minimise rates of preventable healthcare-associated infection (HAI) and acquisition of multidrug resistant organisms, which are among the commonest adverse effects of hospitalisation. Failures of hospital IPC in recent years have led to nosocomial and community outbreaks of emerging infections, causing preventable deaths and social disruption. Therefore, effective IPC programs are essential, but can be difficult to sustain in busy clinical environments. Healthcare workers' adherence to routine IPC practices is often suboptimal, but there is evidence that doctors, as a group, are consistently less compliant than nurses. This is significant because doctors' behaviours disproportionately influence those of other staff and their peripatetic practice provides more opportunities for pathogen transmission. A better understanding of what drives doctors' IPC practices will contribute to development of new strategies to improve IPC, overall. METHODS This qualitative case study involved in-depth interviews with senior clinicians and clinician-managers/directors (16 doctors and 10 nurses) from a broad range of specialties, in a large Australian tertiary hospital, to explore their perceptions of professional and cultural factors that influence doctors' IPC practices, using thematic analysis of data. RESULTS Professional/clinical autonomy; leadership and role modelling; uncertainty about the importance of HAIs and doctors' responsibilities for preventing them; and lack of clarity about senior consultants' obligations emerged as major themes. Participants described marked variation in practices between individual doctors, influenced by, inter alia, doctors' own assessment of patients' infection risk and their beliefs about the efficacy of IPC policies. Participants believed that most doctors recognise the significance of HAIs and choose to [mostly] observe organisational IPC policies, but a minority show apparent contempt for accepted rules, disrespect for colleagues who adhere to, or are expected to enforce, them and indifference to patients whose care is compromised. CONCLUSIONS Failure of healthcare and professional organisations to address doctors' poor IPC practices and unprofessional behaviour, more generally, threatens patient safety and staff morale and undermines efforts to minimise the risks of dangerous nosocomial infection.

Abstract
BACKGROUND Hand hygiene is monitored by direct observation to improve practice, but this approach can potentially cause information, selection, and confounding bias, threatening the validity of findings. The aim of this study was to identify and describe the potential biases in hand hygiene compliance monitoring by direct observation; develop a typology of biases and propose improvements to reduce bias; and increase the validity of compliance measurements. METHODS This systematic review of hospital-based intervention studies used direct observation to monitor health care workers' hand hygiene compliance. RESULTS Seventy-one publications were eligible for review. None was free of bias. Selection bias was present in all studies through lack of data collection on the weekends (n = 61, 86%) and at night (n = 46, 65%) and observations undertaken in single-specialty settings (n = 35, 49%). We observed inconsistency of terminology, definitions of hand hygiene opportunity, criteria, tools, and descriptions of the data collection. Frequency of observation, duration, or both were not described or were unclear in 58 (82%) publications. Observers were trained in 56 (79%) studies. Inter-rater reliability was measured in 26 (37%) studies. CONCLUSIONS Published research of hand hygiene compliance measured by direct observation lacks validity. Hand hygiene should be measured using methods that produce a valid indication of performance and quality. Standardization of methodology would expedite comparison of hand hygiene compliance between clinical settings and organizations.

Comparison of Perceived and Observed Hand Hygiene Compliance in Healthcare Workers in MERS-CoV Endemic Regions. Healthcare (Basel) 2018; 6:healthcare6040122. [PMID: 30301272 PMCID: PMC6315729 DOI: 10.3390/healthcare6040122] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2018] [Revised: 10/02/2018] [Accepted: 10/03/2018] [Indexed: 12/17/2022] Open
Abstract
This study investigated healthcare workers’ perceptions of hand hygiene practices by comparing personal reports, as assessed by questionnaires, to direct observations of the workers’ hand hygiene practices. The study employed a cross-sectional research design. Observations were made using a 16-item checklist, based on three sources: Centers for Disease Control and Prevention (CDC), World Health Organization (WHO), and Boyce and Pittet’s guidelines of hand hygiene. The checklist was used for both direct-observation and self-reported data collection purposes. Pearson correlation and Multivariate Analysis of Covariance (MANCOVA) were utilized to statistically determine the relationship between healthcare workers’ reports of hand hygiene practices and observed hand hygiene behaviors. The study was conducted in the outpatient examination rooms and emergency departments of three types of hospitals in the Eastern region of Saudi Arabia where Middle East respiratory syndrome coronavirus (MERS-CoV) is endemic and is observed in routine cases and outbreaks. The total sample size included 87 physicians and nurses recruited while on duty during the scheduled observation periods, with each healthcare worker being observed during individual medical examinations with at least three patients. No statistically significant correlations between the healthcare workers’ perceptions of hand hygiene practices and healthcare workers’ actual behaviors were evident. Based on the self-report questionnaires, significant differences were found between physicians’ and nurses’ hand hygiene practices reports. Healthcare workers clearly understand the importance of careful hand hygiene practices, but based on researchers’ observations, the medical personnel failed to properly implement protocol-driven hand hygiene applications. However, the significant differences between physicians’ and nurses’ self-reports suggest further inquiry is needed to fully explore these discrepancies.

Abstract
BACKGROUND Good hand hygiene (HH) prevents health care-associated infections. We compared psychosocial and organizational factors associated with HH compliance and perceived need for improvement among physicians, nurses, and allied health professionals (AHPs). METHODS We conducted a mixed-methods study in a 1,600-bed adult tertiary-care hospital in Singapore. Seven focus group discussions were conducted and data were analyzed using thematic analysis. The subsequent cross-sectional survey involved 1,064 staff members. Principal components analysis was performed to derive the latent factor structure that was applied in multivariable analyses. RESULTS All staff members acknowledged that HH was an integral part of their work, but were noncompliant due to competing priorities. Physicians were forgetful but appreciated reminders. Nurses were intrinsically motivated for HH. After adjusting for gender, staff category, seniority, and dermatitis history, having positive knowledge-attitudes-behaviors (odds ratio [OR], 1.44; 95% confidence interval [CI], 1.23-1.69), personal motivators-enablers (OR, 1.60; 95% CI, 1.38-1.86), and emotional motivators (OR, 1.62; 95% CI 1.40-1.88) were positively associated with good HH compliance. Women (OR, 3.91; 95% CI, 1.37-11.11), seniors (OR, 2.88; 95% CI, 1.08-7.68), nurses (OR, 4.05; 95% CI, 1.51-10.87), and staff with personal motivators-enablers for HH (OR, 1.60; 95% CI, 1.08-2.37) were more likely to perceive a need for improvement. CONCLUSIONS Factors influencing self-reported HH differed between health care professional groups. Group-specific interventions are needed to improve compliance.

Abstract
Background Staphylococcus aureus is a major human pathogen that can colonize healthy people mainly in the anterior nares. The aim of the present study was to evaluate S. aureus nasal colonization over time among Portuguese nursing students, including methicillin-resistant S. aureus (MRSA). Methods and findings In this longitudinal cohort study, we collected 280 nasal swabs from nursing students at 14 time points over four years of schooling (2012–2016). The isolates were characterized by pulsed-field gel electrophoresis (PFGE), spa typing, multilocus sequence typing (MLST), and SCCmec typing for MRSA. Among 47 students, 20 (43%) carried methicillin-susceptible S. aureus (MSSA) at admission, but none was colonized with MRSA. A total of 19 students (40%) became colonized after exposure during the nursing training, out of which five carried MRSA. Overall, 39 students (83%) had S. aureus detected at least once during the study period. Among the 97 MSSA isolates, most (65%) belonged to four clones: PFGE A-ST30 (21%), B-ST72 (20%), C-ST508 (13%), and D-ST398 (11%). Three of the five MRSA carriers were colonized with the predominant clone circulating in Portuguese hospitals (ST22-IVh) and two with ST3162-II. Colonization of nursing students was highly dynamic with continuous appearance of strains with distinct PFGE types in the same individual. Conclusions A considerable proportion of students became colonized by S. aureus, including MRSA, during the nursing education, evidencing this population represents an important reservoir of S. aureus. Therefore, education on infection control measures in nursing schools is of major importance.

Abstract
INTRODUCTION Healthcare-associated infections (HAIs) affect millions of patients worldwide annually. Hand hygiene (HH) has been identified as the single most important factor preventing HAIs. The aim of this study was to determine the knowledge regarding hand hygiene practices amongst health care workers, and identifying the areas of gaps in their knowledge. METHODS This cross-sectional analytic study was conducted in two university hospitals in Mashhad, Iran between May 2014 and September 2015. Data was collected using a translated version of the World Health Organization (WHO) Hand Hygiene Knowledge Questionnaire (revised 2009). The questionnaire contained questions on the participants' age, gender, profession, year of the course, formal training in HH and 27 multiple choice and "yes" or "no" questions to assess HH knowledge. Data were entered into IBM SPSS Statistics, Version 16. Descriptive statistical methods and also analytical statistical methods include ANOVA and Independent-samples t-test were used in data analyzing. RESULTS In total, 161 respondents including 32 residents, 92 nurses and 37 nursing assistants enrolled in this study. All study groups had a moderate knowledge of HH. The score of 21% was ≤ 50% (poor) and only 10.6% had a good knowledge score (i.e. the score ≥75%). There was no significant difference in the knowledge level of the participants who had received formal training in HH and those who had not (p=0.68). Also, the mean knowledge score was not associated with age (p=0.12), gender (p=0.84), department (p=0.96) or profession (p=0.43). CONCLUSION This study highlights the importance of applying the multimodal training program addressing providers' knowledge regarding hand hygiene, as well as strategies for cognitive, emotional and behavioral methods such as patient engagement in hand-hygiene interventions.

Abstract
The medical field has long recognized the importance of hand hygiene in preventing health care-associated infections, yet studies indicate that this important task is performed only 40% of the time. Health care workers cite several barriers to optimal performance of hand hygiene, but the time required to perform this task is foremost among them. Introduction of alcohol-based hand rubs, bundled interventions, and incorporation of technologies designed to monitor and promote hand hygiene all represent promising advances in this field.

Abstract
Abstract Objectives: to evaluate the application of hand hygiene technique, according to the World Health Organization (WHO) recommendations, in the neonatal intensive care unit, at a Maternity in Salvador de Bahia, Brazil. Methods: cross-sectional study. Hand hygiene technique by professional category and alcohol solution consumption were systematically registered. For this task an adapted instrument created by the WHO was used and applied using factsheets. The sample was taken from medical physicians, physiotherapists, nurses and nursing technicians. Results: hand hygiene adherence regarding WHO recommendations was deficient in terms of technique and in terms of frequency (adequate technique ranged from 0% to 13.3% between professional categories). Hand hygiene was frequently ignored (27% between physicians and 51.8% between nursing technicians). The moment right after touching surfaces next to patients was the most ignored one. Alcohol gel solution monthly use was only 35% of the expected value for the unit. Conclusions: despite the international investigations and efforts for better results, the adherence and compliance to the hand hygiene guidelines is still deficient and continues to be a major problem.

Abstract
Cruise tourism has become more popular. Long-term personal contact, complex population flows, a lack of medical care facilities, and defective infrastructure aboard most cruise ships is likely to result in the ship becoming an incubator for infectious diseases. In this paper, we use a cruise ship as a research scenario. Taking into consideration personal behavior, the nature and transfer route of the virus across different surfaces, virus reproduction, and disinfection, we studied contact infection of infectious disease on a cruise ship. Using gastroenteritis caused by the norovirus as an example, we analyzed the characteristics of infectious disease propagation based on simulation results under different conditions. We found hand washing are the most important factors affecting virus propagation and passenger infection. It also decides either the total number of virus microorganisms or the virus distribution in different functional areas. The transfer rate between different surfaces is a key factor influencing the concentricity of the virus. A high transfer rate leads to high concentricity. In addition, the risk of getting infected is effectively reduced when the disinfection frequency is above a certain threshold. The efficiency of disinfection of functional areas is determined by total virus number and total contact times of surfaces.

Abstract
BACKGROUND Hand hygiene (HH) is essential in preventing nosocomial infection. The emergency department (ED) is an open portal of entry for pathogens into the hospital system, hence the important sentinel function of the ED personnel. The main objective of this study was to assess the effect of a multimodal improvement strategy on hand hygiene compliance in the ED. METHODS Our study was a prospective before-and-after study to determine the effect of a multimodal improvement strategy on the compliance of HH in the ED according to the My 5 Moments of Hand Hygiene defined by the World Health Organization. Interventions such as education, reminders, and regular feedback on HH performance and role models were planned during the 3 intervention weeks. RESULTS In total, 57 ED nurses and ED physicians were observed in this study, and approximately 1,000 opportunities for handrubs were evaluated during the 3 intervention periods. HH compliance increased significantly from baseline from 18% (74/407) to 41% (77/190) after the first intervention and stabilized to 50% (99/200) and 46% (96/210) after the second and third interventions, respectively. CONCLUSIONS Implementing a multimodal HH improvement program significantly improved the HH compliance of ED personnel.

Abstract
BACKGROUND Although proper hand hygiene among health care workers is an important component of efforts to prevent health care-associated infection, there are few data available on adherence to hand hygiene practices in Japan. OBJECTIVES The aim of this study was to examine hand hygiene adherence at teaching hospitals in Japan. METHODS An observational study was conducted from July to November 2011 in 4 units (internal medicine, surgery, intensive care, and/or emergency department) in 4 geographically diverse hospitals (1 university hospital and 3 community teaching hospitals) in Japan. Hand hygiene practice before patient contact was assessed by an external observer. RESULTS In a total of 3545 health care worker-patient observations, appropriate hand hygiene practice was performed in 677 (overall adherence, 19%; 95% confidence interval, 18%-20%). Subgroup rates of hand hygiene adherence were 15% among physicians and 23% among nurses. The ranges of adherence were 11% to 25% between hospitals and 11% to 31% between units. Adherence of the nurses and the physicians to hand hygiene was correlated within each hospital. There was a trend toward higher hand hygiene adherence in hospitals with infection control nurses, compared with hospitals without them (29% versus 16%). CONCLUSIONS The hand hygiene adherence in Japanese teaching hospitals in our sample was low, even lower than reported mean values from other international studies. Greater adherence to hand hygiene should be encouraged in Japan.

Abstract
OBJECTIVES Our aim was to explore how members of community pharmacy staff perceive and experience the role of procedures within the workplace in community pharmacies. SETTING Community pharmacies in England and Wales. PARTICIPANTS 24 community pharmacy staff including pharmacists and pharmacy support staff were interviewed regarding their view of procedures in community pharmacy. Transcripts were analysed using thematic analysis. RESULTS 3 main themes were identified. According to the 'dissemination and creation of standard operating procedures' theme, community pharmacy staff were required to follow a large amount of procedures as part of their work. At times, complying with all procedures was not possible. According to the 'complying with procedures' theme, there are several factors that influenced compliance with procedures, including work demands, the high workload and the social norm within the pharmacy. Lack of staff, pressure to hit targets and poor communication also affected how able staff felt to follow procedures. The third theme 'procedural compliance versus using professional judgement' highlighted tensions between the standardisation of practice and the professional autonomy of pharmacists. Pharmacists feared being unsupported by their employer for working outside of procedures, even when acting for patient benefit. Some support staff believed that strictly following procedures would keep patients and themselves safe. Dispensers described following the guidance of the pharmacist which sometimes meant working outside of procedures, but occasionally felt unable to voice concerns about not working to rule. CONCLUSIONS Organisational resilience in community pharmacy was apparent and findings from this study should help to inform policymakers and practitioners regarding factors likely to influence the implementation of procedures in community pharmacy settings. Future research should focus on exploring community pharmacy employees' intentions and attitudes towards rule-breaking behaviour and the impact this may have on patient safety.

Abstract
Clostridium species and Bacillus spp. are spore-forming bacteria that cause hospital infections. The spores from these bacteria are transmitted from patient to patient via healthcare workers' hands. Although alcohol-based hand rubbing is an important hand hygiene practice, it is ineffective against bacterial spores. Therefore, healthcare workers should wash their hands with soap when they are contaminated with spores. However, the extent of health care worker hand contamination remains unclear. The aim of this study is to determine the level of bacterial spore contamination on healthcare workers' hands. The hands of 71 healthcare workers were evaluated for bacterial spore contamination. Spores attached to subject's hands were quantitatively examined after 9 working hours. The relationship between bacterial spore contamination and hand hygiene behaviors was also analyzed. Bacterial spores were detected on the hands of 54 subjects (76.1%). The mean number of spores detected was 468.3 CFU/hand (maximum: 3300 CFU/hand). Thirty-seven (52.1%) and 36 (50.7%) subjects were contaminated with Bacillus subtilis and Bacillus cereus, respectively. Nineteen subjects (26.8%) were contaminated with both Bacillus species. Clostridium difficile was detected on only one subject's hands. There was a significant negative correlation between the hand contamination level and the frequency of handwashing (r = -0.44, P < 0.01) and a significant positive correlation between the hand contamination level and the elapsed time since last handwashing (r = 0.34, P < 0.01). Healthcare workers' hands may be frequently contaminated with bacterial spores due to insufficient handwashing during daily patient care.

Abstract
Background A number of strategies exist to reduce Clostridium difficile (C. difficile) transmission. We conducted an economic evaluation of “bundling” these strategies together. Methods We constructed an agent-based computer simulation of nosocomial C. difficile transmission and infection in a hospital setting. This model included the following components: interactions between patients and health care workers; room contamination via C. difficile shedding; C. difficile hand carriage and removal via hand hygiene; patient acquisition of C. difficile via contact with contaminated rooms or health care workers; and patient antimicrobial use. Six interventions were introduced alone and "bundled" together: (a) aggressive C. difficile testing; (b) empiric isolation and treatment of symptomatic patients; (c) improved adherence to hand hygiene and (d) contact precautions; (e) improved use of soap and water for hand hygiene; and (f) improved environmental cleaning. Our analysis compared these interventions using values representing 3 different scenarios: (1) base-case (BASE) values that reflect typical hospital practice, (2) intervention (INT) values that represent implementation of hospital-wide efforts to reduce C. diff transmission, and (3) optimal (OPT) values representing the highest expected results from strong adherence to the interventions. Cost parameters for each intervention were obtained from published literature. We performed our analyses assuming low, normal, and high C. difficile importation prevalence and transmissibility of C. difficile. Results INT levels of the “bundled” intervention were cost-effective at a willingness-to-pay threshold of $100,000/quality-adjusted life-year in all importation prevalence and transmissibility scenarios. OPT levels of intervention were cost-effective for normal and high importation prevalence and transmissibility scenarios. When analyzed separately, hand hygiene compliance, environmental decontamination, and empiric isolation and treatment were the interventions that had the greatest impact on both cost and effectiveness. Conclusions A combination of available interventions to prevent CDI is likely to be cost-effective but the cost-effectiveness varies for different levels of intensity of the interventions depending on epidemiological conditions such as C. difficile importation prevalence and transmissibility.

Abstract
Although they play an important role in infection prevention and control, textile materials and personal protective equipment (PPE) used in health care settings are known to be one of the sources of cross-infection. Gowns are recommended to prevent transmission of infectious diseases in certain settings; however, laboratory and field studies have produced mixed results of their efficacy. PPE used in health care is regulated as either class I (low risk) or class II (intermediate risk) devices in the United States. Many organizations have published guidelines for the use of PPE, including isolation gowns, in health care settings. In addition, the Association for the Advancement of Medical Instrumentation published a guidance document on the selection of gowns and a classification standard on liquid barrier performance for both surgical and isolation gowns. However, there is currently no existing standard specific to isolation gowns that considers not only the barrier resistance but also a wide array of end user desired attributes. As a result, infection preventionists and purchasing agents face several difficulties in the selection process, and end users have limited or no information on the levels of protection provided by isolation gowns. Lack of knowledge about the performance of protective clothing used in health care became more apparent during the 2014 Ebola epidemic. This article reviews laboratory studies, regulations, guidelines and standards pertaining to isolation gowns, characterization problems, and other potential barriers of isolation gown selection and use.

Abstract
OBJECTIVE Despite the recognition that educating healthcare students in patient safety is essential, changing already full curricula can be challenging. Furthermore, institutions may lack the capacity and capability to deliver patient safety education, particularly from the start of professional practice studies. Using senior students as peer educators to deliver practice-based education can potentially overcome some of the contextual barriers in training junior students. Therefore, this study aimed to evaluate the effectiveness of a peer-led patient safety education programme for junior pharmacy students. DESIGN A repeat cross-sectional design utilising a previously validated patient safety attitudinal survey was used to evaluate attitudes prior to, immediately after and 1 month after the delivery of a patient safety education programme. Latent growth curve (LGC) modelling was used to evaluate the change in attitudes of first-year students using second-year students as a comparator group. SETTING Undergraduate university students in Sydney, Australia. PARTICIPANTS 175 first-year and 140 second-year students enrolled in the Bachelor of Pharmacy programme at the University of Sydney. INTERVENTION An introductory patient safety programme was implemented into the first-year Bachelor of Pharmacy curriculum at the University of Sydney. The programme covered introductory patient safety topics including teamwork, communication skills, systems thinking and open disclosure. The programme consisted of 2 lectures, delivered by a senior academic, and a workshop delivered by trained final-year pharmacy students. RESULTS A full LGC model was constructed including the intervention as a non-time-dependent predictor of change (χ(2) (51)=164.070, root mean square error of approximation=0.084, comparative fit index=0.913, standardised root mean square=0.056). First-year students' attitudes significantly improved as a result of the intervention, particularly in relation to internalising errors (p=0.010), questioning behaviours (p<0.001) and open disclosure (p=0.008). CONCLUSIONS Peer-led education is an effective method that can be adopted to improve junior pharmacy students' attitudes towards patient safety.

Abstract
In a prevalence study of 209 healthcare workers, 18 (8.6%) and 13 (6.2%) carried methicillin-resistant Staphylococcus aureus in their nares or on their hands, respectively. However, 100 (62%) of 162 workers completing an associated survey believed themselves to be colonized, revealing a knowledge deficit about methicillin-resistant Staphylococcus aureus epidemiology.

Abstract
OBJECTIVE To determine whether hand hygiene adherence is influenced by peer effects and, specifically, whether the presence and proximity of other healthcare workers has a positive effect on hand hygiene adherence. DESIGN An observational study using a sensor network. SETTING A 20-bed medical intensive care unit at a large university hospital. PARTICIPANTS Hospital staff assigned to the medical intensive care unit. METHODS We deployed a custom-built, automated, hand hygiene monitoring system that can (1) detect whether a healthcare worker has practiced hand hygiene on entering and exiting a patient's room and (2) estimate the location of other healthcare workers with respect to each healthcare worker exiting or entering a room. RESULTS We identified a total of 47,694 in-room and out-of-room hand hygiene opportunities during the 10-day study period. When a worker was alone (no recent healthcare worker contacts), the observed adherence rate was 20.85% (95% confidence interval [CI], 19.78%-21.92%). In contrast, when other healthcare workers were present, observed adherence was 27.90% (95% CI, 27.48%-28.33%). This absolute increase was statistically significant (P < .01). We also found that adherence increased with the number of nearby healthcare workers but at a decreasing rate. These results were consistent at different times of day, for different measures of social context, and after controlling for possible confounding factors. CONCLUSIONS The presence and proximity of other healthcare workers is associated with higher hand hygiene rates. Furthermore, our results also indicate that rates increase as the social environment becomes more crowded, but with diminishing marginal returns.

Abstract
Objectives.To assess the prevalence and correlates of compliance and noncompliance with hand hygiene guidelines in hospital care.Design.A systematic review of studies published before January 1, 2009, on observed or self-reported compliance rates.Methods.Articles on empirical studies written in English and conducted on general patient populations in industrialized countries were included. The results were grouped by type of healthcare worker before and after patient contact. Correlates contributing to compliance were grouped and listed.Results.We included 96 empirical studies, the majority (n= 65) in intensive care units. In general, the study methods were not very robust and often ill reported. We found an overall median compliance rate of 40%. Unadjusted compliance rates were lower in intensive care units (30%–40%) than in other settings (50%–60%), lower among physicians (32%) than among nurses (48%), and before (21%) rather than after (47%) patient contact. The majority of the time, the situations that were associated with a lower compliance rate were those with a high activity level and/or those in which a physician was involved. The majority of the time, the situations that were associated with a higher compliance rate were those having to do with dirty tasks, the introduction of alcohol-based hand rub or gel, performance feedback, and accessibility of materials. A minority of studies (n= 12) have investigated the behavioral determinants of hand hygiene, of which only 7 report the use of a theoretical framework with inconclusive results.Conclusions.Noncompliance with hand hygiene guidelines is a universal problem, which calls for standardized measures for research and monitoring. Theoretical models from the behavioral sciences should be used internationally and should be adapted to better explain the complexities of hand hygiene.

Abstract
Objective.To study potential determinants of hand hygiene compliance among healthcare workers in the hospital setting.Design.A qualitative study based on structured-interview guidelines, consisting of 9 focus group interviews involving 58 persons and 7 individual interviews. Interview transcripts were subjected to content analysis.Setting.Intensive care units and surgical departments of 5 hospitals of varying size in the Netherlands.Participants.A total of 65 nurses, attending physicians, medical residents, and medical students.Results.Nurses and medical students expressed the importance of hand hygiene for preventing of cross-infection among patients and themselves. Physicians expressed the importance of hand hygiene for self-protection, but they perceived that there is a lack of evidence that handwashing is effective in preventing cross-infection. All participants stated that personal beliefs about the efficacy of hand hygiene and examples and norms provided by senior hospital staff are of major importance for hand hygiene compliance. They further reported that hand hygiene is most often performed after tasks that they perceive to be dirty, and personal protection appeared to be more important for compliance that patient safety. Medical students explicitly mentioned that they copy the behavior of their superiors, which often leads to noncompliance during clinical practice. Physicians mentioned that their noncompliance arises from their belief that the evidence supporting the effectiveness of hand hygiene for prevention of hospital-acquired infections is not strong.Conclusion.The results indicate that beliefs about the importance of self-protection are the main reasons for performing hand hygiene. A lack of positive role models and social norms may hinder compliance.

Abstract
Background Clostridium difficile is one of the most common and important nosocomial pathogens, causing severe gastrointestinal disease in hospitalized patients. Although "bundled" interventions have been proposed and promoted, optimal control strategies remain unknown. Methods We designed an agent-based computer simulation of nosocomial C. difficile transmission and infection, which included components such as: patients and health care workers, and their interactions; room contamination via C. difficile shedding; C. difficile hand carriage and removal via hand hygiene; patient acquisition of C. difficile via contact with contaminated rooms or health care workers; and patient antimicrobial use. We then introduced six interventions, alone and "bundled" together: aggressive C. difficile testing; empiric isolation and treatment of symptomatic patients; improved adherence to hand hygiene and contact precautions; improved use of soap and water for hand hygiene; and improved environmental cleaning. All interventions were tested using values representing base-case, typical intervention, and optimal intervention scenarios. Findings In the base-case scenario, C. difficile infection rates ranged from 8–21 cases/10,000 patient-days, with a case detection fraction between 32%–50%. Implementing the "bundle" at typical intervention levels had a large impact on C. difficile acquisition and infection rates, although intensifying the intervention to optimal levels had much less additional impact. Most of the impact came from improved hand hygiene and empiric isolation and treatment of suspected C. difficile cases. Conclusion A "bundled" intervention is likely to reduce nosocomial C. difficile infection rates, even under typical implementation conditions. Real-world implementation of the "bundle" should focus on those components of the intervention that are likely to produce the greatest impact on C. difficile infection rates, such as hand hygiene and empiric isolation and treatment of suspected cases.

Abstract
Hand hygiene compliance remains suboptimal among physicians despite quality improvement efforts. We observed hand hygiene compliance among 29 medicine interns at 2 large academic institutions. Overall compliance was 75%. Although 4 interns averaged <40% compliance, 14 averaged at least 80%. Given variability observed among individuals in the same training programs, targeting those with poor performance may be important in improving overall compliance.

Abstract
BACKGROUND Hand hygiene is the most important measure to reduce health care-related infections and colonization with multiresistant micro-organisms. We sought to determine the rate and seasonality of handwashing compliance in a university-affiliated hospital. METHODS In January 2006 (baseline period), handwashing observation was first made in an intensive care unit. From March to May 2006, there was an intervention period; and, from June 2006 to August 2009, we followed hand hygiene compliance. Seasonality curves for handwashing compliance were made during follow-up period. RESULTS During baseline period, a total of 166 observations was made. During follow-up, 17,664 opportunities for hand hygiene were observed. Compliance improved from 30.0% to a mean of 56.7% after the intervention (P < .001). The highest mean rate of compliance was 77.9% for nurses, compared with 52.6% for technicians (P < .001) and 44.6% for physicians (P < .001). Compliance was lower during summer days (first trimester of the year) and increased after March and April and slowly decreased through the end of the year. CONCLUSION One of the reasons for the lower handwashing compliance in the first 3 months of the year is that, in Brazil, this is the summer vacation time; and, because of that, the staff's workload and the number of less well-trained personnel are higher. We emphasize the importance of continuously monitoring hand hygiene to determine the seasonal aspects of compliance.

Abstract
BACKGROUND We described a systematic process for improving hand hygiene (HH) compliance in health care providers and assessed the impact of HH on patient outcomes. METHODS This retrospective cohort study was conducted between July 2008 and September 2011 in a children's hospital. We employed failure mode effectiveness analysis to identify barriers for complying with HH requirements and instituted improvement measures. We conducted a subanalysis using methicillin-resistant Staphylococcus aureus (MRSA) acquisition data and HH compliance data collected in the neonatal intensive care unit (NICU) to demonstrate the impact of HH on patient outcomes. RESULTS The overall HH compliance rate increased from 50.3% preintervention (July 2008-September 2008) to 84.0% postintervention (January 2009-September 2011) (relative risk [RR], 1.7; 95% confidence interval [CI]: 1.6-1.9). Compliance among physicians and nurses increased from 48.6% to 87.0% (RR, 1.4; 95% CI: 1.3-1.6) and from 46.5% to 77.9% (RR, 1.3; 95% CI: 1.2-1.4), respectively. Sustaining HH at 80% or higher was associated with a 48% further reduction of MRSA acquisition (incident rate ratio, -0.52; 95% CI: -0.31 to -0.90) in a unit that had comprehensive MRSA prevention measures. This reduction represents the prevention of 1.3 MRSA acquisitions per month, resulting in a saving of 11.6 NICU-days and $66,397 hospital charges. CONCLUSION This study demonstrated the utility of failure mode effectiveness analysis to improve staff HH and suggested HH as a potential cost-effective means for preventing MRSA in hospitals.

Abstract
BACKGROUND This study evaluates hand hygiene behavior of health care workers in a German university hospital stratified for treatment of special patient groups (eg, transplant patients). METHODS From 2008 to 2010, comprehensive education and training of all health care workers was implemented to improve hand hygiene compliance. Consumption rates of alcohol-based hand rub and gloves were collected and evaluated. RESULTS Of the 5,647 opportunities of hand disinfection evaluated, 1,607 occurred during care for transplant patients. To our knowledge, this is the largest survey of hand hygiene compliance in special patient groups on intensive care units in a university hospital in Germany. Health care workers on surgical intensive care units showed lower hand hygiene compliance compared with health care workers on other types of intensive care units. Compliance toward hand hygiene was significantly higher on hemato-oncologic and pediatric wards. In general, hand disinfection was performed significantly more frequently after an intervention than before (P < .05, 95% confidence interval: 1.24-1.84). Overall, there was no significant difference in hand hygiene compliance when caring for transplant patients or other patients (odds ratio, 1.16; 95% confidence interval: 0.95-1.42). Nurse's and physician's hand hygiene compliance improved because of education. CONCLUSION Hand hygiene compliance is not increased in the care for transplant patients (despite their predisposition for nosocomial infections) compared with other patients. Additional studies will be necessary to further investigate these findings.

Abstract
BACKGROUND Implementation of a hospital-wide program of terminal cleaning of patient rooms revolving around hydrogen peroxide vapor (HPV) technology and evaluation of its impact on endemic nosocomial Clostridium difficile-associated diarrhea (CDAD) have not been previously reported. METHODS This was a retrospective quasiexperimental study involving a 900-bed community hospital. During the preintervention period (January 2007-November 2008), rooms vacated by patients with CDAD or on contact precautions for other targeted pathogens underwent 1 or more rounds of cleaning with bleach. During the intervention period (January-December 2009), targeted newly evacuated rooms underwent "enhanced cleaning" consisting of use of bleach followed by HPV decontamination utilizing a priority scale based on the pathogen and room location. Rooms vacated by patients with CDAD but for which HPV decontamination was not possible the same day underwent 4 rounds of cleaning with bleach instead. RESULTS During the intervention period, 1,123 HPV decontamination rounds were performed involving 96.7% of hospital rooms. Of 334 rooms vacated by patients with CDAD (May-December 2009), 180 (54%) underwent HPV decontamination. The rate of nosocomial CDAD rate dropped significantly from 0.88 cases/1,000 patient-days to 0.55 cases/1,000 patient-days (rate ratio, 0.63; 95% confidence interval: 0.50-0.79, P < .0001). CONCLUSION A hospital-wide program of enhanced terminal cleaning of targeted patient rooms revolving around HPV technology was practical and was associated with a significant reduction in CDAD rates.

Abstract
Hand hygiene is regarded as the most effective means of preventing healthcare associated infection. However, systematic reviews provide limited evidence of effectiveness, a finding that is attributed to the poor quality of research designs, dubious outcome measures and flawed approaches to audit. The ability of interventions to improve hand hygiene compliance has not previously been questioned. This review categorises the types of interventions used to promote hand hygiene and discusses their plausibility, taking selected examples from previous systematic searches. Opinion leaders have emphasised the need for interventions to be underpinned by theory. This is an ambitious endeavour for infection control personnel based in National Health Service trusts. However, it is possible to offer pragmatic suggestions to promote compliance. Initiatives are most likely to be successful if needs analysis is undertaken at the outset to address local barriers and identify enablers to compliance, and if interventions are clearly justified by existing evidence, customised according to occupational group, consider health workers’ needs and preferences for training and updating, and avoid punishment.

Abstract
BACKGROUND Hand hygiene (HH) is single most effective preventive measure for health care-associated infection, but compliance rates remain low. This study estimated HH compliance among health care workers (HCWs) and examined factors associated with noncompliance. METHODS An observational study design was carried out in 5 intensive care units (ICUs) at the University Hospital in Riyadh, Saudi Arabia. Among 242 HCWs, a total of 3,940 HH opportunities were observed by 6 trained medical interns and students. The World Health Organization's "Five Moments for Hand Hygiene" procedure was used as a basis for the observations. RESULTS The overall observed noncompliance rate was 58%. The factors associated with noncompliance were HCW job title (physicians, odds ratio [OR], 2.8; 95% confidence interval [CI], 1.8-4.2; allied health professionals, OR, 2.9, 95% CI, 1.9-4.6); working the a.m. shift (OR, 1.5; 95% CI, 1.3-1.8), working in a pediatric ICU (OR, 1.8; 95% CI, 1.5-2.2), and performance of HH before patient contact (OR, 4.5; 95% CI, 2.6-7.8). CONCLUSIONS Overall HH noncompliance was high in ICUs of this hospital. The demanding ICU work setting was an important factor associated with noncompliance. HH compliance was highest among therapists and technicians because of fewer patient interactions and thus fewer HH noncompliance opportunities per person. Further studies on the relationship between work environment demands and HH compliance rates are needed.

Abstract
BACKGROUND As the predominant occupation in the health sector and as the health worker with the most patient interaction, nurses are at high risk for occupational transmission of communicable respiratory illness. The use of facial protective equipment (FPE) is an important strategy to prevent occupational transmission. METHODS A 2-phased study was conducted to examine nurse's adherence to recommended use of FPE. Phase 1 was a cross-sectional survey of nurses in selected units of 6 acute care hospitals in Toronto, Canada. Phase 2 was a direct observational study of critical care nurses. RESULTS Of the 1,074 nurses who completed surveys (82% response rate), 44% reported adherence to recommended use of FPE. Multivariable analysis revealed 6 predictors of adherence: unit type, frequency of equipment use, equipment availability, training, organizational support, and communication. Following the survey, 100 observations in 14 intensive care units were conducted that revealed a 44% competence rate with proper use of N95 respirators and knowledge as a significant predictor of competence. CONCLUSION Whereas increasing knowledge should enhance competence, strategies to improve adherence to recommended use of FPE in a busy and complex health care setting should focus on ready availability of equipment, training and fit testing, organizational support for worker health and safety, and good communication practices.

Abstract
We conducted an observational study to identify predictors of hand hygiene (HH) in the emergency department. Compliance with HH was 89.7% over 5,865 opportunities. Observation unit, hallway or high-visibility location, glove use, and worker type predicted worse HH. Hallway location was the strongest predictor (relative risk, 88.9% [95% confidence interval, 85.9%-92.1%]).

Abstract
The aim of this study was to evaluate the nurses' hand-washing behaviour and knowledge before and after a training programme. This prospective study involved 200 nurses who participated in hand-washing training at a university hospital in Turkey. The data were collected using a personal information form and pre- and post-test surveys that had been developed by the researchers. During the study, the nurses received 40 min of training on hand washing and a handbook prepared by the researchers. The hand-washing behaviour and knowledge of the nurses were assessed before training and 1 month after the training. To analyse the data, descriptive statistics, a t-test and a Mc Nemar chi-squared test were used. Following the training, there was a significant increase in the frequency of hand washing by the nurses (t = -2.202, P = 0.029), together with an increase in the time allowed for hand washing (P = 0.024, P < 0.05), knowledge of hand-washing practices (t = -16.081, P < 0.05) and quality (t = -10.874, P < 0.05). Planned training programmes for hand washing should be implemented to improve the behaviour and knowledge of nurses.

Abstract
Due to a longstanding comprehensive "search and destroy policy", methicillin-resistant Staphylococcus aureus (MRSA) is not endemic in Western Australian (WA) acute care hospitals. As the prevalence of MRSA in the community has increased, healthcare workers (HCW) are at risk of importing MRSA into hospitals. We aimed to determine the prevalence of and risk factors for nasal MRSA colonization in our HCW population. A period prevalence study was conducted at an 850-bed tertiary hospital. Basic demographics and a nasal swab were obtained. A total of 1,542 HCWs employed in our centre were screened for MRSA, of whom 3.4% (n = 52) were colonized. MRSA colonization was more common in patient care assistants (6.8%) and nurses (5.2%) than in allied health professionals (1.7%) and doctors (0.7%) (p < 0.01). Working in "high-risk" wards that cared for MRSA colonized/infected patients was the strongest risk factor for HCW MRSA colonization (p < 0.001). ST1-IV and ST78-IV (the most common community clones in the region) were the most frequently identified clones. In conclusion, MRSA colonization of HCWs occurs primarily in HCWs caring for patients colonized or infected with MRSA. Surveillance screening of HCWs should be regularly performed on wards with patients with high MRSA colonization prevalence to prevent further spread in the hospital.

Abstract
OBJECTIVE To use quality-improvement (QI) methods to develop and test a multimodal intervention to improve hand-hygiene compliance among health care workers (HCWs) to >90%. METHODS We used a quasi-experimental staggered intervention that was conducted on 2 similar general pediatric units within a 475-bed tertiary children's hospital. Compliance was defined as acceptable hand hygiene both before and after contact with the patient or the patient's care environment. Measurement of HCW hand-hygiene compliance was performed by covert observations made during routine patient care. Twelve months of preintervention data were collected. QI methods were used to test and implement interventions sequentially in each unit. Interventions addressed leadership support, improving HCW knowledge, hand-hygiene supply availability, and HCW behavior. RESULTS Interventions began on unit A on November 10, 2008. Similar interventions were later tested on unit B starting March 23, 2009. By April 1, 2009, compliance increased on unit A (from 65% to 91%) and unit B (from 74% to 92%). Improvement on each unit occurred only after the interventions were introduced. Identifying HCWs who failed to perform hand hygiene and offering alcohol-based hand rub to them before patient contact resulted in the greatest improvement. Improvements were sustained on both units for 18 months. CONCLUSIONS Use of QI methods to implement a multimodal intervention resulted in sustained improvement in hand-hygiene compliance. Real-time individual performance feedback or other high-reliability human-factor interventions seem to be necessary to reach and sustain high levels of hand-hygiene compliance.

Abstract
We examined hand hygiene practices in surgical wards in 9 countries in Europe and Israel through direct practice observation. There was marked interhospital variation in hand hygiene compliance (range, 14%-76%), as well as glove and alcohol-based handrub use. After multivariable analysis, surgical subspecialty, professional category, type of care activity, and workload were independently associated with compliance. Hand hygiene practices are influenced by numerous factors, and a tailored approach may be required to improve practices.
