The CleanYourHandsCampaign: critiquing policy and evidence base

Prevention of microbial colonization of feeding tubes in the intensive care unit

BACKGROUND

Various microorganisms which increase the mortality rate in the intensive care unit (ICU) cause microbial colonization of the nasogastric tube (NGT) and use the NGT as a reservoir.

AIM

To detect the colonization on the NGT and to determine the effect that training regarding hand hygiene, NGT management, and enteral feeding (EF) provided to ICU nurses and auxiliary service staff (ASS) has on the level of NGT colonization.

STUDY DESIGN

A quasi-experimental pre-test and post-test control design was used in this study. Microbial samples were taken from the outer and inner parts of NGT. The microorganisms were categorized as: group 1, no risk; group 2, low risk pathogenic; group 3, high-risk pathogenic group. The training was given to nurses (n = 15) and ASS (n = 7). Hand hygiene, NGT, and EF care training are provided to nurses and ASS by researchers. A total of three training sessions were scheduled to be held in 3 weeks so that all health care staff members were trained. Each session lasted 2 h in total. Patients were assigned to a group if one of the microorganisms presented on the outer surface of the patient's feeding tube and/or on the hub. The hand hygiene compliance was evaluated by direct observation according to the World Health Organization hand hygiene indications.

RESULTS

The study was conducted with 46 patients. Evaluating the patients for the presence of microorganisms before education revealed that 4.3% were in group 1, 21.8% were in group 2, and 73.9% were in group 3. After the education, evaluating the samples for the presence of microorganisms revealed that 39.1% were in group 1, 13% were in group 2, and 47.8% were in group 3. A statistically significant difference was found between the number of samples included in the groups after the participants had received training (H = 8.186; p = .017).

CONCLUSIONS

An NGT could act as a reservoir of microbial colonization and high-risk microorganisms could be on the tube. Providing training not only to nurses but also to ASS will help reduce the risk of colonization.

RELEVANCE TO CLINICAL PRACTICE

Eliminating such colonization with effective hand hygiene during NGT feeding is a cost-effective method. Providing training not only to nurses but also to ASS will help obtain the optimum benefit from patient care.

Canadian policy changes for alcohol-based hand rubs during the COVID-19 pandemic and unintended risks

The COVID-19 pandemic led to major changes in public policies to address supply chain disruption and escalated the price of consumer disinfectant products. To address market demands on alcohol-based hand rubs and disinfectants, Health Canada implemented major changes to the regulations regarding composition, handling, transportation, and packaging to insure product availability. Furthermore, accelerated licensing of ingredients and packaging did not meet standard medical quality guidelines yet were authorized for manufacturing and packaging of alcohol-based hand rubs and disinfectants. The accountability associated with these policy changes were reactive, including industry self-reporting, consumer reporting, and Health Canada advisories and recalls that were responsive to products after they were available in the market. Nonetheless, Canadian public health policy increased hand sanitizers availability. However, some of the interim policies have raised major public health concerns associated with ethanol quality, packaging, and labeling, and enforcement of regulations. In this paper, we review the changes in the Canadian regulations amid the current pandemic and we evaluate the unintended health risks that might arise from these changes.

Barriers and facilitators of tuberculosis infection prevention and control in low- and middle-income countries from the perspective of healthcare workers: A systematic review

Tuberculosis remains a leading cause of death worldwide. Transmission is the dominant mechanism sustaining the multidrug-resistant tuberculosis epidemic. Tuberculosis infection prevention and control (TBIPC) guidelines for healthcare facilities are poorly implemented. This systematic review aimed to explore the barriers and facilitators of implementation of TBIPC guidelines in low- and middle-income countries from the perspective of healthcare workers. Two separate reviewers carried out an electronic database search to select qualitative and quantitative studies exploring healthcare workers attitudes towards TBIPC. Eligible studies underwent thematic synthesis. Derived themes were further organised into a macro-, meso- and micro-level framework, which allows us to analyse barriers at different levels of the healthcare system. We found that most studies focused on assessing implementation within facilities in accordance with the hierarchy of TBIPC measures—administrative, environmental and respiratory protection controls. TBIPC implementation was over-estimated by self-report compared with what researchers observed within facilities, indicating a knowledge-action gap. Macro-level barriers included the lack of coordination of integrated HIV/tuberculosis care, in the context of an expanding antiretroviral therapy programme and hence increasing opportunity for nosocomial acquisition of tuberculosis; a lack of funding; and ineffective occupational health policies, such as poor systems for screening for tuberculosis amongst healthcare workers. Meso-level barriers included little staff training to implement programmes, and managers not understanding policy sufficiently to translate it into an IPC programme. Most studies reported micro-level barriers including the impact of stigma, work culture, lack of perception of risk, poor supply and use of respirators and difficulty sensitising patients to the need for IPC. Existing literature on healthcare workers’ attitudes to TBIPC focusses on collecting data about poor implementation at facility level. In order to bridge the knowledge-action gap, we need to understand how best to implement policy, taking account of the context.

The neglected element of hand hygiene - significance of hand drying, efficiency of different methods and clinical implication: A review

Hand hygiene is a fundamental strategy for controlling the spread of infection. Careful hand drying is integral to the process of hand hygiene, which aims to optimise the removal of potentially pathogenic microorganisms. Ineffective hand drying results in wet hands that are an infection risk increasing the potential for cross-infection, occupational contact dermatitis for healthcare practitioners, harm to patients and environmental contamination. Evidence indicates that there has been limited research regarding the significance of hand drying and the efficacy and clinical impact of different drying methods. The purpose of this review paper was to scope and evaluate the existing literature pertaining to hand drying; to examine the clinical consequences associated with wet hands for patients, healthcare practitioners and the clinical environment; to assess the efficacy of different drying methods; to consider the impact on patient safety; and to progress the research, debate and practice relating to hand drying. The methodological framework applied in this review was that of Arksey and O'Malley (2007). Twenty-one papers identified from 112 abstracts screened were included in the review. Analysis identified three primary themes emerging from the literature: (1) efficacy of hand drying methods; (2) drying method and microbial translocation, dispersion and environmental contamination; and (3) drying methods and environmental sustainability. This review highlights the equal importance of hand drying in the process of hand hygiene and suggests that the efficacy of hand drying is a critical factor in the prevention of the transfer of microorganisms to the environment, and from person to person following hand washing. In conclusion, this paper argues that greater attention needs to be given to hand drying in terms of practice, policy and research and its importance in clinical settings given greater focus.

Patient Safety Culture and the Ability to Improve: A Proof of Concept Study on Hand Hygiene

OBJECTIVE To investigate whether the safety culture of a hospital unit is associated with the ability to improve. DESIGN Qualitative investigation of safety culture on hospital units following a before-and-after trial on hand hygiene. SETTING VU University Medical Center, a tertiary-care hospital in the Netherlands. METHODS With support from hospital management, we implemented a hospital-wide program to improve compliance. Over 2 years, compliance was measured through direct observation, twice before, and 4 times after interventions. We analyzed changes in compliance from baseline, and selected units to evaluate safety culture using a positive deviance approach: the hospital unit with the highest hand hygiene compliance and 2 units that showed significant improvement (21% and 16%, respectively) were selected as high performing. Another 2 units showed no improvement and were selected as low performing. A blinded, independent observer conducted interviews with unit management, physicians, and nurses, based on the Hospital Survey on Patient Safety Culture. Safety culture was categorized as pathological (lowest level), reactive, bureaucratic, proactive, or generative (highest level). RESULTS Overall, 3 units showed a proactive or generative safety culture and 2 units had bureaucratic or pathological safety cultures. When comparing compliance and interview results, high-performing units showed high levels of safety culture, while low-performing units showed low levels of safety culture. CONCLUSIONS Safety culture is associated with the ability to improve hand hygiene. Interventions may not be effective when applied in units with low levels of safety culture. Although additional research is needed to corroborate our findings, the safety culture on a unit can benefit from enhancement strategies such as team-building exercises. Strengthening the safety culture before implementing interventions could aid improvement and prevent nonproductive interventions. Infect Control Hosp Epidemiol 2017;38:1277-1283.

Poor Hand Hygiene Procedure Compliance among Polish Medical Students and Physicians-The Result of an Ineffective Education Basis or the Impact of Organizational Culture?

Objective: The objective of the study was to examine the knowledge of Polish physicians and medical students about the role of hand hygiene (HH) in healthcare-associated infection (HAI) prevention. Study design: A survey was conducted using an author-prepared questionnaire, which was filled out on the first day of hospital work (or internship) by newly admitted physicians who had worked in other hospitals and students of different medical schools in Poland. Methods: 100 respondents participated in the study: 28 students, 18 medical interns and 54 physicians. Results: As many as 3/4 of physicians and students did not use the HH techniques correctly. The respondents declared that they perform HH in the following situations: 74.4% of respondents before an aseptic task; 60.8% before patient contact; 57.0% after patient contact; 11.5% after body fluid exposure risk, and only two respondents (1.1%) after contact with patient surroundings. 64% of respondents declared that their supervisor checked their knowledge of the HH technique when they were touching patients, but their supervisors checked the five instances for HH only in the case of 27 respondents (27%). Students experienced any control of HH in the workplace less often. Interns and physicians mentioned that the most important preventive action in HAI is HH, but for students it is the use of gloves. Conclusions: The level of knowledge and skills of physicians and students in the field of HH is insufficient. Deficiencies in skills and knowledge of HH were identified as early as at the level of the first internship.

Foetal surgery and using in utero therapies to reduce the degree of disability after birth. Could it be morally defensible or even morally required?

In 2008 the Human Fertilisation and Embryology Act amendments made deliberately choosing to bring disability into the world, using assisted reproduction, a criminal offence. This paper considers whether the legal prohibition above, should influence other policy areas concerning the welfare of future children such as new possibilities presented by foetal surgery and in utero gene therapy. If we have legal duties to avoid disability in one context should this influence our avoidance of disability in this other context? This paper investigates whether the State might have a stake in wider promotion of practices to reduce the degree of disability in foetuses that will come to exist (as opposed to those that will be aborted). Not selecting for disability does not affect the welfare of any future individual, whereas treating in utero abnormalities can optimize the eventual child's welfare; antenatal interventions stand to improve clinical outcomes and welfare should that specific child be born. I explore why the State may want to intervene in the antenatal setting and to what extent, if at all; the State should implement these technologies. I argue that if the State is justified in intervening to outlaw the choosing to create disabled lives using assisted reproductive techniques, it is also justified in putting pressure on prospective parents to accept therapies in utero to help their child be born less disabled. However, I qualify this with the argument that the State is not justified in using force or the criminal law in this situation during pregnancy.

Staphylococcus aureus dry-surface biofilms are not killed by sodium hypochlorite: implications for infection control

BACKGROUND

Dry hospital environments are contaminated with pathogenic bacteria in biofilms, which suggests that current cleaning practices and disinfectants are failing.

AIM

To test the efficacy of sodium hypochlorite solution against Staphylococcus aureus dry-surface biofilms.

METHODS

The Centers for Disease Control and Prevention Biofilm Reactor was adapted to create a dry-surface biofilm, containing 1.36 × 10(7)S. aureus/coupon, by alternating cycles of growth and dehydration over 12 days. Biofilm was detected qualitatively using live/dead stain confocal laser scanning microscopy (CLSM), and quantitatively with sonicated viable plate counts and crystal violet assay. Sodium hypochlorite (1000-20,000parts per million) was applied to the dry-surface biofilm for 10min, coupons were rinsed three times, and residual biofilm viability was determined by CLSM, plate counts and prolonged culture up to 16 days. Isolates before and after exposure underwent minimum inhibitory concentration (MIC) and minimum eradication concentration (MEC) testing, and one pair underwent whole-genome sequencing.

FINDINGS

Hypochlorite exposure reduced plate counts by a factor of 7 log10, and reduced biofilm biomass by a factor of 100; however, staining of residual biofilm showed that live S. aureus cells remained. On prolonged incubation, S. aureus regrew and formed biofilms. Post-exposure S. aureus isolates had MICs and MECs that were not significantly different from the parent strains. Whole-genome sequencing of one pre- and post-exposure pair found that they were virtually identical.

CONCLUSIONS

Hypochlorite exposure led to a 7-log kill but the organisms regrew. No resistance mutations occurred, implying that hypochlorite resistance is an intrinsic property of S. aureus biofilms. The clinical significance of this warrants further study.

Modeling the hospital safety partnership preferences of patients and their families: a discrete choice conjoint experiment

BACKGROUND

Patients and their families play an important role in efforts to improve health service safety.

OBJECTIVE

The objective of this study is to understand the safety partnership preferences of patients and their families.

METHOD

We used a discrete choice conjoint experiment to model the safety partnership preferences of 1,084 patients or those such as parents acting on their behalf. Participants made choices between hypothetical safety partnerships composed by experimentally varying 15 four-level partnership design attributes.

RESULTS

Participants preferred an approach to safety based on partnerships between patients and staff rather than a model delegating responsibility for safety to hospital staff. They valued the opportunity to participate in point of service safety partnerships, such as identity and medication double checks, that might afford an immediate risk reduction. Latent class analysis yielded two segments. Actively engaged participants (73.3%) comprised outpatients with higher education, who anticipated more benefits to safety partnerships, were more confident in their ability to contribute, and were more intent on participating. They were more likely to prefer a personal engagement strategy, valued scientific evidence, preferred a more active approach to safety education, and advocated disclosure of errors. The passively engaged segment (26.7%) anticipated fewer benefits, were less confident in their ability to contribute, and were less intent on participating. They were more likely to prefer an engagement strategy based on signage. They preferred that staff explain why they thought patients should help make care safer and decide whether errors were disclosed. Inpatients, those with immigrant backgrounds, and those with less education were more likely to be in this segment.

CONCLUSION

Health services need to communicate information regarding risks, ask about partnership preferences, create opportunities respecting individual differences, and ensure a positive response when patients raise safety concerns.

A realist analysis of hospital patient safety in Wales: applied learning for alternative contexts from a multisite case study

Background

Hospital patient safety is a major social problem. In the UK, policy responses focus on the introduction of improvement programmes that seek to implement evidence-based clinical practices using the Model for Improvement, Plan-Do-Study-Act cycle. Empirical evidence that the outcomes of such programmes vary across hospitals demonstrates that the context of their implementation matters. However, the relationships between features of context and the implementation of safety programmes are both undertheorised and poorly understood in empirical terms.

Objectives

This study is designed to address gaps in conceptual, methodological and empirical knowledge about the influence of context on the local implementation of patient safety programmes.

Design

We used concepts from critical realism and institutional analysis to conduct a qualitative comparative-intensive case study involving 21 hospitals across all seven Welsh health boards. We focused on the local implementation of three focal interventions from the 1000 Lives+patient safety programme: Improving Leadership for Quality Improvement, Reducing Surgical Complications and Reducing Health-care Associated Infection. Our main sources of data were 160 semistructured interviews, observation and 1700 health policy and organisational documents. These data were analysed using the realist approaches of abstraction, abduction and retroduction.

Setting

Welsh Government and NHS Wales.

Participants

Interviews were conducted with 160 participants including government policy leads, health managers and professionals, partner agencies with strategic oversight of patient safety, advocacy groups and academics with expertise in patient safety.

Main outcome measures

Identification of the contextual factors pertinent to the local implementation of the 1000 Lives+patient safety programme in Welsh NHS hospitals.

Results

An innovative conceptual framework harnessing realist social theory and institutional theory was produced to address challenges identified within previous applications of realist inquiry in patient safety research. This involved the development and use of an explanatory intervention–context–mechanism–agency–outcome (I-CMAO) configuration to illustrate the processes behind implementation of a change programme. Our findings, illustrated by multiple nested I-CMAO configurations, show how local implementation of patient safety interventions are impacted and modified by particular aspects of context: specifically, isomorphism, by which an intervention becomes adapted to the environment in which it is implemented; institutional logics, the beliefs and values underpinning the intervention and its source, and their perceived legitimacy among different groups of health-care professionals; and the relational structure and power dynamics of the functional group, that is, those tasked with implementing the initiative. This dynamic interplay shapes and guides actions leading to the normalisation or the rejection of the patient safety programme.

Conclusions

Heightened awareness of the influence of context on the local implementation of patient safety programmes is required to inform the design of such interventions and to ensure their effective implementation and operationalisation in the day-to-day practice of health-care teams. Future work is required to elaborate our conceptual model and findings in similar settings where different interventions are introduced, and in different settings where similar innovations are implemented.

Intensive care unit environmental surfaces are contaminated by multidrug-resistant bacteria in biofilms: combined results of conventional culture, pyrosequencing, scanning electron microscopy, and confocal laser microscopy

BACKGROUND

Hospital-associated infections cause considerable morbidity and mortality, and are expensive to treat. Organisms causing these infections can be sourced from the inanimate environment around a patient. Could the difficulty in eradicating these organisms from the environment be because they reside in dry surface biofilms?

AIM

The intensive care unit (ICU) of a tertiary referral hospital was decommissioned and the opportunity to destructively sample clinical surfaces was taken in order to investigate whether multidrug-resistant organisms (MDROs) had survived the decommissioning process and whether they were present in biofilms.

METHODS

The ICU had two 'terminal cleans' with 500 ppm free chlorine solution; items from bedding, surrounds, and furnishings were then sampled with cutting implements. Sections were sonicated in tryptone soya broth and inoculated on to chromogenic plates to demonstrate MDROs, which were confirmed with the Vitek2 system. Genomic DNA was extracted directly from ICU samples, and subjected to polymerase chain reaction (PCR) for femA to detect Staphylococcus aureus and the microbiome by bacterial tag-encoded FLX amplicon pyrosequencing. Confocal laser scanning microscopy (CLSM) and scanning electron microscopy (SEM) were performed on environmental samples.

FINDINGS

Multidrug-resistant bacteria were cultured from 52% (23/44) of samples cultured. S. aureus PCR was positive in 50%. Biofilm was demonstrated in 93% (41/44) of samples by CLSM and/or SEM. Pyrosequencing demonstrated that the biofilms were polymicrobial and contained species that had multidrug-resistant strains.

CONCLUSION

Dry surface biofilms containing MDROs are found on ICU surfaces despite terminal cleaning with chlorine solution. How these arise and how they might be removed requires further study.

The 'My five moments for hand hygiene' concept for the overcrowded setting in resource-limited healthcare systems

Hand hygiene is a core activity of patient safety for the prevention of healthcare-associated infections (HCAIs). To standardize hand hygiene practices globally the World Health Organization (WHO) released Guidelines on Hand Hygiene in Health Care and introduced the 'My five moments for hand hygiene' concept to define indications for hand hygiene rooted in an evidence-based model for transmission of micro-organisms by healthcare workers' (HCWs) hands. Central to the concept is the division of the healthcare environment into two geographical care zones, the patient zone and the healthcare zone, that requires the HCW to comply with specific hand hygiene moments. In resource-limited, overcrowded healthcare settings inadequate or no spatial separation between beds occurs frequently. These conditions challenge the HCW's ability to visualize and delineate patient zones. The 'My five moments for hand hygiene' concept has been adapted for these conditions with the aim of assisting hand hygiene educators, auditors, and HCWs to minimize ambiguity regarding shared patient zones and achieve the ultimate goal set by the WHO Guidelines--the reduction of infectious risks.

Quantitative assessment of organizational culture within hospitals and its relevance to infection prevention and control strategies

It has been suggested that organizational culture (OC) is an important driver of infection prevention and control (IPC) behaviour among healthcare workers. This study examined OC in seven European hospitals using a validated assessment tool based on Hofstede's model, and identified significant variations in OC scores. Hospitals with low prevalence of meticillin-resistant Staphylococcus aureus (MRSA) exhibited high scores for change facilitation and change readiness, whereas hospitals with high prevalence of MRSA exhibited low scores for these determinants. It is possible to use tools, available outside health care, to study OC within hospitals and gain better insight into IPC behaviour change strategies.

Social Marketing Analysis of 2 Years of Hand Hygiene Promotion

Objective.

To assess published hand hygiene behavioral interventions that employed a social marketing framework and to recommend improvements to future interventions.

Methods.

We performed a systematic literature review by searching the PubMed database and the Cumulative Index to Nursing and Allied Health Literature for published articles about hand hygiene behavioral interventions in healthcare facilities, schools, and community settings. Our analysis included articles that describe multifaceted interventions and evaluated them with predefined social marketing benchmark criteria.

Results.

Of 53 interventions analyzed in this review, 16 (30.2%) employed primary formative audience research, 5 (9.4%) incorporated social or behavioral theories, 27 (50.9%) employed segmentation and targeting of the audience, 44 (83.0%) used components of the “marketing mix,” 3 (5.7%) considered the influence of competing behaviors, 7 (13.2%) cultivated relationships with the target audience, and 15 (28.3%) provided simple behavioral messages. Thirty-five (66.0%) of the interventions demonstrated a significant improvement in performance, but only 21 (39.6%) were considered to have a strong evaluative design. The median duration of the interventions was 8.0 months.

Conclusions.

From a social marketing perspective, the promotion of hand hygiene could be improved in several ways. The effectiveness of social marketing in hand hygiene promotion should be tested in future interventions.

Lowbury Lecture 2013. Cultural determinants of infection control behaviour: understanding drivers and implementing effective change

Despite dealing with biomedical practices, infection prevention and control (IPC) is essentially a behavioural science. Human behaviour is influenced by various factors, including culture. Hofstede's model of cultural dimensions proposes that national cultures vary along consistent dimensions which can be grouped and scored as specific constructs. Studies have reported that three Hofstede constructs--power distance, uncertainty avoidance, and masculinity--show significant association with several key performance indicators relevant to IPC and antibiotic stewardship. In addition, national meticillin-resistant Staphylococcus aureus (MRSA) levels within Europe correlate well with general quality-of-care indices, including preventive strategies and patient rights. This suggests that IPC may be simply a microcosm of overall quality and safety standards within hospitals and countries. Effective improvement would therefore need to address underlying and embedded core cultural values relevant to patient safety and quality of care. Successful IPC strategies are likely to be those that are compatible with the cultural background where they are implemented. To this end, content analysis of many current IPC improvement tools identifies elements of strong compatibility with cultures that are low in uncertainty avoidance and power distance, and high in individualism and masculinity. However, this cultural combination is largely restricted to Anglo-Saxon countries, where most of the recent improvements in healthcare-associated infection (HCAI) incidence have taken place. There is a paucity of research on IPC behaviour change in different cultural backgrounds, especially countries that score high for power distance and/or uncertainty avoidance. This information is vital to inform IPC campaigns in these countries, which often show high HCAI prevalence.

Use of hand-held computers to determine the relative contribution of different cognitive, attitudinal, social, and organizational factors on health care workers' decision to decontaminate hands

BACKGROUND

Observational and survey methods have limitations in measuring hand hygiene behavior. The ability of a personal digital assistant to anonymously gather data at the point of decision making could potentially address these.

METHODS

Participants were provided with a personal digital assistant to be used for three 2-hour periods and asked to rate influential factors of the Health Belief Model (HBM). Participants were also required to enter what they thought they should do and what they actually did.

RESULTS

A total of 741 hand hygiene opportunities was recorded. All HBM constructs were higher for hand hygiene opportunities where there was compliance versus noncompliance, with a significant difference for patient pressure, my risk, perceived benefits, perceived seriousness, and availability of good facilities. Only 20% of doctors, 28% of nurses, and 66% of physiotherapists always did what they thought they should. There was no correlation between self-reported and actual compliance.

CONCLUSION

The HBM appeared to be a useful theoretical framework. Surprisingly, participants rated their compliance as high despite having recorded instances where they did not do what they thought they should do. This suggests that staff may have a different definition of compliance than strict observation of the guidelines.

Patient empowerment in a hand hygiene program: differing points of view between patients/family members and health care workers in Asian culture

BACKGROUND

"Patient empowerment" is an important component of World Health Organization hand hygiene program, but little is known about the intentions and attitude of patients/families and health care workers (HCWs) regarding this.

METHODS

A cross-sectional survey using questionnaires was conducted in a tertiary teaching hospital in Taiwan to assess hand hygiene knowledge and the attitudes and intentions regarding patient empowerment among patients/families and HCWs.

RESULTS

Among patients/families, 95.4% (329/345) had positive attitudes regarding patient empowerment; however, only 67.2% (232/345) had the positive intention to remind HCWs about hand hygiene (P < .001). Risk factors for negative intention were being female (odds ratio [OR], 1.82; 95% confidence interval [CI]: 1.08-3.03), illiteracy (OR, 3.18; 95% CI: 0.86-11.7), and being patients/families in the pediatric department (OR, 1.86; 95% CI: 0.93-3.64). Among HCWs, the difference between positive attitude (81.1%; 714/880) and positive intention regarding being reminded about hand hygiene (62.8%; 553/880) was significant (P < .001). Risk factors for negative intention were age > 25 years (OR, 3.20; 95% CI: 1.51-6.81) and a negative attitude toward patient empowerment (OR, 10.00; 95% CI: 5.88-16.67).

CONCLUSION

There were significant gaps between attitude and intention regarding patient empowerment both among patients/families and HCWs. Special strategies targeting women, the pediatric population, or illiterate people may help improve patient/family participation. Additionally, hand hygiene education should be incorporated into early-stage medical/nursing education to create a facilitating environment. Patients/families and HCWs cooperation is needed to promote the hand hygiene program further.

Student and infection prevention and control nurses’ hand hygiene decision making in simulated clinical scenarios: a qualitative research study of hand washing, gel and glove use choices

Final year nursing students and infection prevention and control nurses were recorded verbalising their hand hygiene decision-making while working through clinical scenarios on a computer, to understand what factors they were taking into account in choosing a decontamination method (hand washing or alcohol based hand rub/gel) or to wear gloves. Results demonstrated an overuse of gloves, and underuse of gel. Three main themes emerged: ‘Experience or expectation’; this was what they had seen on placement, or it was what ‘we’ do. ‘Just in case,’ was characterised by an awareness that what they would do wasn’t actually necessary but they tended to do it anyway. Thirdly, ‘gel doesn’t feel clean,’ was characterised by a feeling that using gel didn’t make the nurses feel clean after ‘dirty’ tasks, even though gel is actually more effective. There was little evidence that participants were making risk assessments based on the individual patient characteristics given, or the tasks, as they had been taught to do. Choice of hand decontamination agent and whether to use gloves appeared to be based on an habitual characterisation of whether the task was ‘clean’ or ‘dirty,’ with a very low threshold for ‘dirty’ based on an excessive perception of risk to the student.

Impact on hand hygiene compliance following migration to a new hospital with improved resources and the sequential introduction of World Health Organization recommendations

BACKGROUND

One commonly cited reason for inadequate hand hygiene (HH) in health care facilities is lack of handwashing sinks and alcohol hand rub (AHR).

METHODS

Using the World Health Organization (WHO) direct observation method, we studied HH compliance after migration from an old hospital having 1 HH station (sink and AHR) per 6 beds to a new institution with 1 per 0.85 beds. We then introduced the other WHO strategy components in a sequential manner-posters, active education, and performance feedback-and assessed the impact of the various elements over time.

RESULTS

Migration from the old to the new hospital was actually accompanied by a reduction in HH from 27.3% to 14.5% (P < .01), with a 52% decline in handwashing (P = .01) after patient contact. Small group interactive teaching improved HH compliance but only reached a maximum of 33.1%. No change was seen where only posters and leaflets (without educational sessions) were adopted. Significant improvement was only obtained after a performance feedback campaign coupled with increased staff accountability, reaching an overall average of 63% (P < .001).

CONCLUSION

Our results suggest that, on their own, better resources do not offer any guarantees of improved HH practices. However, once in place, audit and feedback-coupled with genuine administrative support and fostering of individual accountability-appear to be effective change tools to increase HH compliance.

Understanding the epidemiology of MRSA in Europe: do we need to think outside the box?

BACKGROUND

The epidemiology of meticillin-resistant Staphylococcus aureus (MRSA) infections, using bacteraemia as a marker, shows a striking geographical pattern in Europe. The prevalence of MRSA is low in Northern European countries, increases into central Europe and reaches its highest levels in the Mediterranean region. This has been attributed to varying levels of implementation of infection control and antibiotic stewardship (ICAS) programmes, but reasons for this variation have not been clearly established.

AIM

To investigate the possible impact of national cultural dimensions on the epidemiology of MRSA in Europe.

METHODS

Median proportions of MRSA bacteraemia were sourced for countries participating in the EARS-Net surveillance network in 2010, and correlated with the national cultural dimension scores of Hofstede et al.

FINDINGS

Significant associations were identified between MRSA proportions and the cultural constructs of uncertainty avoidance (UAI), masculinity (MAS) and power distance. Multiple regression models found significant associations for UAI, MAS and short-term orientation (R(2) adjusted = 0.475; P < 0.001). The model was found to be predictive of MRSA trends identified in several European countries between 2006 and 2010.

CONCLUSION

Implementation of ICAS programmes often requires behavioural change. Cultural dimensions appear to be key factors affecting perceptions and values among healthcare workers, which in turn are critical for compliance and uptake. Customizing ICAS initiatives to reflect the local cultural background may improve their chances of success.

Where do hands go? An audit of sequential hand-touch events on a hospital ward

BACKGROUND

Reservoirs of pathogens could establish themselves at forgotten sites on a ward, posing a continued risk for transmission to patients via unwashed hands.

AIM

To track potential spread of organisms between surfaces and patients, and to gain a greater understanding into transmission pathways of pathogens during patient care.

METHODS

Hand-touch activities were audited covertly for 40 × 30 min sessions during summer and winter, and included hand hygiene on entry; contact with near-patient sites; patient contact; contact with clinical equipment; hand hygiene on exit; and contact with sites outside the room.

FINDINGS

There were 104 entries overall: 77 clinical staff (59 nurses; 18 doctors), 21 domestic staff, one pharmacist and five relatives. Hand-hygiene compliance among clinical staff before and after entry was 25% (38/154), with higher compliance during 20 summer periods [47%; 95% confidence interval (CI): 35.6-58.8] than during 20 winter periods (7%; 95% CI: 3.2-14.4; P < 0.0001). More than half of the staff (58%; 45/77) touched the patient. Staff were more likely to clean their hands prior to contact with a patient [odds ratio (OR): 3.44; 95% CI: 0.94-16.0); P = 0.059] and sites beside the patient (OR: 6.76; 95% CI: 1.40-65.77; P = 0.0067). Nearly half (48%; 37/77) handled patient notes and 25% touched the bed. Most frequently handled equipment inside the room were intravenous drip (30%) and blood pressure stand (13%), and computer (26%), notes trolley (23%) and telephone (21%) outside the room.

CONCLUSION

Hand-hygiene compliance remains poor during covert observation; understanding the most frequent interactions between hands and surfaces could target sites for cleaning.

Patient safety and healthcare-associated infection

Healthcare-associated infection (HCAI) has become a major patient safety issue in National Health Service (NHS) hospitals. The UK has an HCAI prevalence rate of 8.2% which equates to an annual incidence of approximately 300000 patients (Hospital Infection Society, 2007). HCAI is a safety issue because it is associated with increased morbidity and mortality as well as increased healthcare costs (National Audit Office (NAO), 2009). In 2000, the NAO identified cultural change as a requirement if the NHS is to get a grip of infection prevention and control. This article has taken a 'conceptual culture of safety model' that has been previously described in the literature and applied it to the organization of infection control. It is clear that while there are many areas of good practice, in relation to infection prevention and control, there is still much to do if the NHS is to invoke the type of paradigm shift that will result in a mature sustainable safety culture.

Observation-based evaluation of hand hygiene practices and the effects of an intervention at a public hospital cafeteria

BACKGROUND

Hand hygiene is important before meals, especially in a hospital cafeteria where patrons may have had recent contact with infectious agents. Few interventions to improve hand hygiene have had measureable success. This study was designed to use a poster intervention to encourage hand hygiene among health care workers (HCWs) and hospital visitors (HVs) upon entry to a hospital cafeteria.

METHODS

Over a 5-week period, a poster intervention with an accessible hand sanitizer unit was deployed to improve hand hygiene in a hospital cafeteria. The dependent variable observed was hand hygiene attempts. Study phases included a baseline, intervention, and follow-up phase, with each consisting of 3 randomized days of observation for 3 hours during lunch.

RESULTS

During the 27 hours of observation, 5,551 participants were observed, and overall hand hygiene frequency was 4.79%. Hygiene attempts occurred more frequently by HCWs than HVs (P = .0008) and females than males (P = .0281). Hygiene attempts occurred more frequently after poster introduction than baseline (P = .0050), and this improvement was because of an increase in frequency of HV hand hygiene rather than HCW hand hygiene.

CONCLUSION

The poster intervention tool with easily accessible hand sanitizer can improve overall hand hygiene performance in a US hospital cafeteria.

Control of transmission of infection in hospitals requires more than clean hands

The focus on hand hygiene appears timely, given the problems that we have with transmission of infection in our hospitals. Unfortunately, people do not always clean their hands when they should, and even if they do, there are other factors that contribute to the acquisition of infection. Nonadherence to hand hygiene is now being targeted by the introduction of more rigorous assessment in healthcare environments. “Zero tolerance” mandates are facilitating managerial pursuit of poor hand hygiene, with a variety of disciplinary outcomes. This article questions the priority afforded hand hygiene and its enforcement and asks whether we should reconsider additional infection control strategies rather than threaten staff over hand hygiene practices.

A review of hand-washing techniques in primary care and community settings

AIM

This review seeks to identify the most effective hand-washing and hand-cleansing practice that could be used in primary care.

BACKGROUND

Healthcare associated infection is a major problem in the UK causing 5000 deaths every year. Current guidelines indicate expert opinion is the level of evidence for hand washing as an activity to reduce infection.

DESIGN

Systematic review.

METHOD

Publications on hand-washing, hand-cleansing studies, policy and practice-based documents were sought by searching several databases. Terms used included hand washing, hand cleansing, hand hygiene, hand decontamination, infection control and primary care.

RESULTS

Few articles described the hand-washing technique in detail and some publications simply referred to either the European and British Standards or the Centre for Disease Control statement on hand washing. Major discrepancies in hand position and water flow direction were found. Several methodological problems were also identified and few studies were undertaken in primary care.

CONCLUSION

This review has found a lack of evidence for hand-washing techniques being undertaken in practice today. Findings from hand-washing technique studies were inconclusive and methodological issues exist resulting in sparse reliable evidence. There is an urgent need to undertake methodologically sound studies of hand-washing techniques for use in the ever expanding scope of primary care practice.

RELEVANCE TO CLINICAL PRACTICE

Evidence for hand-washing and hand-cleansing techniques will inform healthcare professional practice, and contribute to the overall management of infection control in primary care.

[Assessment of a hand hygiene program on healthcare-associated infection control]

AIM

to assess the impact of a hand hygiene campaign on the rate of healthcare-associated infections in a teaching hospital in Las Palmas.

METHODS

Ecological design by hand hygiene frequency measurement at three high risk areas along with infection rates calculation over four periods of time: baseline (2005), phase 1 (2006), phase 2 (2007), and post-intervention (2008). Multi-modal intervention comprised the introduction of alcoholic solutions for rubbing hands, feedback on observed compliance, design and placement of posters, and healthcare workers training through all clinician areas. Variables measurement was carried out according to standardized criteria.

RESULTS

an increase in hand hygiene compliance was achieved over the tree periods of compliance surveillance, from 19.6% at baseline to 40.0% (p<0.001) at the last period. The increase was higher among those opportunities for hand hygiene considered as high risk for pathogen transmission (from 12.0% to 28.4%; p<0.001), but only after phase 1, and for medium risk opportunities. Infection rates did not low in every area under surveillance, especially prevalence of infected patients, which increased from 8% in 2005 to 12.2% in 2008.

CONCLUSIONS

Despite the increase in adherence to hand hygiene at the areas under surveillance, health-care associated infections were not lowered hospital-wide. A more comprehensive strategy should be implemented, increasing managers and directors support in every task related to infection control.

Improvements in hand hygiene across New South Wales public hospitals: clean hands save lives, part III

OBJECTIVE

To describe improvements in hand hygiene compliance after a statewide hand hygiene campaign conducted in New South Wales public hospitals.

DESIGN AND SETTING

The campaign was conducted in all area health services in NSW (covering all 208 public hospitals). Alcohol-based hand rub (AHR) was introduced into all hospitals between March and June 2006. In each hospital, five overt observation surveys of hand hygiene compliance by health care workers (HCWs) were conducted: one pre-implementation survey and four post-implementation surveys (in August 2006, November 2006, February 2007 and July 2008).

MAIN OUTCOME MEASURES

Overtly observed hand hygiene compliance rates by HCWs, stratified by before- and after-patient contact, Fulkerson's contact risk categories, and four health care professional groupings.

RESULTS

The overall hand hygiene compliance rate improved from 47% before the intervention to an average of 61% over the last three observation periods (P < 0.001). All professional groups sustained improved compliance rates except medical staff, whose practices reverted to pre-intervention rates. Nursing staff maintained significantly improved compliance, with an average rate of 67% after the intervention. Overall hand hygiene compliance before patient contact improved from 39% (pre-campaign) to 52% (July 2008) (P < 0.001). Overall compliance after patient contact improved from 57% to 64% (P < 0.001) over the same period. Compliance associated with medium-risk contacts increased from an average of 51% in the first two observation periods to an average of 62% over the last three observation periods (P < 0.001). The corresponding compliance rates associated with low-risk contacts were 35% and 56%, respectively (P < 0.001).

CONCLUSION

An overall improvement in hand hygiene rates was achieved with the introduction of AHR. Increased adherence to before-patient contact compliance, especially by nursing staff, contributed to the progress made, but an acceptable overall level of hand hygiene practice is yet to be achieved. It is now time to focus on a long-term behavioural change program directed specifically at medical staff.

Patient participation: current knowledge and applicability to patient safety

Patient participation is increasingly recognized as a key component in the redesign of health care processes and is advocated as a means to improve patient safety. The concept has been successfully applied to various areas of patient care, such as decision making and the management of chronic diseases. We review the origins of patient participation, discuss the published evidence on its efficacy, and summarize the factors influencing its implementation. Patient-related factors, such as acceptance of the new patient role, lack of medical knowledge, lack of confidence, comorbidity, and various sociodemographic parameters, all affect willingness to participate in the health care process. Among health care workers, the acceptance and promotion of patient participation are influenced by other issues, including the desire to maintain control, lack of time, personal beliefs, type of illness, and training in patient-caregiver relationships. Social status, specialty, ethnic origin, and the stakes involved also influence patient and health care worker acceptance. The London Declaration, endorsed by the World Health Organization World Alliance for Patient Safety, calls for a greater role for patients to improve the safety of health care worldwide. Patient participation in hand hygiene promotion among staff to prevent health care-associated infection is discussed as an illustrative example. A conceptual model including key factors that influence participation and invite patients to contribute to error prevention is proposed. Further research is essential to establish key determinants for the success of patient participation in reducing medical errors and in improving patient safety.

Experimental pretesting of hand-washing interventions in a natural setting

OBJECTIVES

We pretested interventions derived from different domains of behavior change theory to determine their effectiveness at increasing hand washing with soap in a natural setting.

METHODS

We installed wireless devices in highway service station restrooms to record entry and soap use. Two text-only messages for each of 7 psychological domains were compared for their effect on soap-use rates. We collected data on nearly 200 000 restroom uses.

RESULTS

The knowledge activation domain was most effective for women, with a relative increase in soap use of 9.4% compared with the control condition (P = .001). For men, disgust was the most effective, increasing soap use by 9.8% (P = .001). Disgust was not significantly better than the control condition for women, nor was knowledge activation for men. Messages based on social norms and social status were effective for both genders.

CONCLUSIONS

Our data show that unobtrusive observation of behavior in a natural setting can help identify the most effective interventions for changing behaviors of public health importance. The gender differences we found suggest that public health interventions should target men and women differently.

Storytelling: its place in infection control education

It is generally accepted that hand hygiene is the single most effective measure to prevent health care associated infection. Similarly, education is thought to be the cornerstone of effective practice. While common sense supports the notion that hand hygiene compliance would be enhanced by producing a well informed health care worker, traditional didactic methods of teaching are often poor at invoking and sustaining behaviour change. Storytelling is gaining popularity as an educational activity as it is said to stimulate thought, reflection and enhance the learning experience. This paper, describes one way in which storytelling may be used within a hand hygiene improvement strategy.

Infection control, ethics and accountability

Health care-associated infections (HAIs) are a major clinical and economic problem in Australian hospitals, and a significant proportion are preventable. HAIs are the result of complex environmental, microbiological, pathological, behavioural and organisational factors, and prevention requires a multifaceted ("bundled") approach, including appropriate policies, educational programs for health care workers, and adequate resources to implement them effectively. Failure to protect patients from avoidable harm, including HAIs, has significant ethical implications; it often reflects both organisational systems failure and non-compliance of health care workers with evidence-based policies, including hand hygiene. If implemented with appropriate safeguards, infection control "bundles" that include sanctions for poor compliance with hand hygiene and other infection control policies, will achieve sustained improvements where previous approaches have failed.

A systematic review of safety violations in industry

It is widely known that intentional non-malevolent violations of safety procedures and norms occur and evidence shows that safety violations can increase the risk of accidents. However, little research about the causes of these violations in work settings exists. To help shed light on the causes, this paper systematically reviews the empirical causes of safety violations in industry. Electronic database literature searches were performed to identify relevant articles published prior to January 1, 2007. Thirteen articles met the inclusion criteria and 57 different variables were examined as predictors of safety violations. Study settings were healthcare delivery, commercial driving, aviation, mining, railroad, and construction. The predictors were categorized into individual characteristics, information/education/training, design to support worker needs, safety climate, competing goals, and problems with rules. None of the reviewed studies examined whether violations can improve system performance or safety. Methodological suggestions and a macroergonomic framework are offered for improving future studies of the epidemiology of safety violations.

Exploring the hand hygiene competence of student nurses: a case of flawed self assessment

Hand hygiene remains the single most effective measure to prevent hospital acquired infection and yet poor compliance is reported repeatedly. Nurses represent the largest labour group and perform the greatest amount of direct patient care in the contemporary National Health Service. They receive their initial hand hygiene training in the pre-registration curriculum within a competence framework based on knowledge, skills and attitudes. The pre-eminent training method is one that delivers behavioural competence, making the tacit assumption that compliance will follow. In this study a mixed methods approach demonstrated that students overestimated their knowledge and skills, found it difficult to give an objective account of their performance, and reported an improbable level of compliance. The reasons why people can be self serving in their judgements may be due to information processing errors, exacerbated by the model of education and training. Flawed self assessments may present major barriers to improved performance if students view their compliance as better than it actually is. Conceptualising hand hygiene as a taxonomy of learning and introducing the cognitive strategies of reflection and self assessment would better enable students to problem solve, seek out new information, draw on past experience and gain greater and deeper understanding of the complex topic of hand hygiene behaviour.
