Hand hygiene adherence is influenced by the behavior of role models

Compliance and Performance of Hand Hygiene in Dutch General Practice Offices Using Electronic Dispensers

INTRODUCTION

One of the most effective measures for the reduction and prevention of healthcare-associated infections (HAI) is hand hygiene (HH). Covert direct observation of HH is difficult to realize in general practice office (GPO). The World Health Organization recognizes electronic monitoring as a form of measuring product use and estimating compliance. This is the first study to monitor HH performance electronically in Dutch GPOs.

OBJECTIVES

The main aim of this study was to evaluate HH compliance in general practice offices.

METHODS

An observational study was conducted at 4 Dutch GPOs between 2019 and 2021. We measured HH compliance using data on HH events (HHE) from alcohol-based hand rub (ABHR) dispensers with a built-in electronic counter. Daily HH opportunities were calculated according to the 'Five Moments for Hand Hygiene' based on the continuously documented activities using general practitioners (GPs) patient electronic dossier systems.

RESULTS

In total, hand hygiene was performed during 1786 of the estimated 4322 opportunities (41%). HH compliance for the general practitioners, practice assistants, and nurse practitioners was 38%, 51%, and 43%, respectively. The overall HH compliance within the same GPOs was 42% pre-pandemic and rose to 56% during the pandemic. The overall mean volume of ABHR was 2.44 ml, varying per HHE between 1.91 to 2.55 ml. The mean volume of ABHR measured before and during the pandemic rose from 2.55 ml to 2.81 ml. The overall self-reported compliance was 86% and was highest among nurse practitioners.

CONCLUSIONS

Hand hygiene compliance among HCWs in Dutch GPOs was found to be 41%, with general practitioners having the lowest compliance and practice assistants the highest compliance. While the mean volume of ABHR used per HHE seems appropriate, directed observations would be needed to ensure that an adequate hand-rub technique was used to cover the whole hand. Multi-modal interventions are needed to improve HH-compliance and stimulate the switch to ABHR with in the Dutch general practice office.

Impact of and strategies to address negative role models and adherence of nursing students to standard precautions: An integrative review

BACKGROUND

Negative role models can significantly impact nursing students' adherence to standard infection control precautions (SP) but there has been limited research on impacts and relevant strategies.

PURPOSE

This review examined the impact of negative role models on nursing students' adherence to SP and explored strategies that nursing instructors could use to help students effectively manage the influence of negative role models.

METHODS

An integrative review was conducted, guided by Whittemore and Knafl's methodology (2005). PubMed, CINAHL, and Scopus were searched for articles from 2008-2023. Research studies were critically appraised using appropriate tools.

RESULTS

Fourteen articles met the inclusion criteria and were included in this review. The literature indicates that nursing students frequently encounter negative role models during their clinical placements and that such negative encounters detrimentally impact their adherence to SP. Five strategies to potentially mitigate the impact of negative role models were identified.

CONCLUSION

To address the issue of negative role models, nursing instructors can help students learn specific strategies to manage encounters with negative role models, promote discussion of role modeling with students and clinical staff, and act as role models themselves. Further research is needed to inform specific strategies.

Navigating a Pandemic: Leadership Dynamics and Challenges within Infection Prevention and Control Units in Israel

This study investigates the impact of the coronavirus disease 2019 (COVID-19) pandemic on leadership within infection prevention and control (IPC) units across public hospitals in Israel. Through qualitative interviews with ten IPC managers from nine hospitals, equivalent to 30% of the country's acute care facilities, the research uncovers significant changes in managerial approaches due to the health crisis. The results reveal four main themes: (1) Enhanced managerial autonomy and leadership skills, with a noted rise in self-efficacy against the pandemic's backdrop; (2) Shifted perceptions of IPC units by upper management, recognizing their strategic value while identifying the need for a more profound understanding of IPC operations; (3) The increased emphasis on adaptability and rapid decision-making for effective crisis management; (4) The dual effect on job satisfaction and well-being, where greater commitment coincides with risks of burnout. The study underscores the essential nature of effective IPC leadership during emergencies, highlighting the need for clear communication, prompt action, and empathetic leadership. The conclusions point to the necessity for continuous research into IPC leadership, promoting strategic advancements in management to bolster IPC units against future health threats.

Sticky apps, not sticky hands: A systematic review and content synthesis of hand hygiene mobile apps

OBJECTIVE

The study sought to identify smartphone apps that support hand hygiene practice and to assess their content, technical and functional features, and quality. A secondary objective was to make design and research recommendations for future apps.

MATERIALS AND METHODS

We searched the UK Google Play and Apple App stores for hand hygiene smartphone apps aimed at adults. Information regarding content, technical and functional features was extracted and summarized. Two raters evaluated each app, using the IMS Institute for Healthcare Informatics functionality score and the Mobile App Rating Scale (MARS).

RESULTS

A total of 668 apps were identified, with 90 meeting the inclusion criteria. Most (96%) were free to download. The majority (78%) intended to educate or inform or remind users to hand wash (69%), using behavior change techniques such as personalization and prompting practice. Only 20% and 4% named a best practice guideline or had expert involvement in development, respectively. Innovative means of engagement were used in 42% (eg, virtual or augmented reality or geolocation-based reminders). Apps included an average of 2.4 out of 10 of the IMS functionality criteria (range, 0-8). The mean MARS score was 3.2 ± 0.5 out of 5, and 68% had a minimum acceptability score of 3. Two had been tested or trialed.

CONCLUSIONS

Although many hand hygiene apps exist, few provide content on best practice. Many did not meet the minimum acceptability criterion for quality or were formally trialed or tested. Research should assess the feasibility and effectiveness of hand hygiene apps (especially within healthcare settings), including when and how they "work." We recommend that future apps to support hand hygiene practice are developed with infection prevention and control experts and align with best practice. Robust research is needed to determine which innovative methods of engagement create "sticky" apps.

Electronic Hand Hygiene Quality and Duration Monitoring in Pre-School Children: A Feasibility Study

BACKGROUND

Hand hygiene is regarded as the most important measure to prevent spread of infectious diseases. The aim of this study was to assess the feasibility of a prototype application in an electronic device in educating, stimulating and monitoring hand hygiene quality in young children.

METHOD

A pre-school was provided with an interactive hand hygiene application for two months. The device features an online administrator dashboard for data collection and for monitoring the children's hand washing steps and duration. A good hand washing is defined as hand washing which comprise all of the steps outlined in the World Health Organization (WHO) guidelines.

RESULTS

The prototype managed to capture 6882 hand wash performed with an average of 20.85 seconds per hand wash. Washing hands palm to palm was the most frequent (79.9%) step performed, whereas scrubbing fingernails and wrists were the least (56%) steps performed.

CONCLUSIONS

The device is a good prototype to educate, stimulate and monitor good hand hygiene practices. However, other measures should be undertaken to ensure sustainability of the practices.

[Discussion groups as an approach to assess knowledge, attitudes and practices of hand hygiene among the adult intensive care unit professionals from a referral hospital]

OBJECTIVES

The adherence to hand hygiene practices among the adult Intensive Care Unit (ICU) professionals in this hospital has not improved substantially in the last years, regardless of the theoretical training sessions conducted. A study was made of the knowledge, attitudes, and practices of the ICU personnel in this field.

METHODS

Several small discussion groups with ICU staff organised by preventive medicine professionals were scheduled in March 2018. Semi-structured questions on hand hygiene and use of gloves were included. The points discussed were listed into strengths and weaknesses. Knowledge was then assessed using an anonymous questionnaire, after the sessions.

RESULTS

Thirteen 60-minute sessions were carried out with 157 participants from all professional categories (82% from ICU, median=11 participants / session). The majority perceived hand hygiene as a priority issue of personal responsibility for patient safety. They identified factors that limit their ability to improve their adherence. Certain habits have more to do with personal preferences than with theoretical knowledge or technical indications.

CONCLUSIONS

The discussion groups have helped to make a diagnosis of the situation that will be useful to strengthen those areas of improvement that have been identified. If we aim for a cultural change, and eliminate incorrect habits, it seems more useful to carry out adequate continuing education as part of the daily routine of professionals.

Hand hygiene knowledge, attitudes, and practices among hospital inpatients: A descriptive study

BACKGROUND

Pathogens may be transmitted in hospitals via patients' own hands, but little is known about the facilitators and barriers of hand hygiene among inpatients. This study aimed to assess the hand hygiene knowledge, attitudes, and practices of adult inpatients at 5 hospitals.

METHODS

The study consisted of a cross-sectional survey distributed followed by structured interviews with randomly selected inpatients. Qualitative data were analyzed independently by 2 researchers using the Theoretical Domains Framework.

RESULTS

A total of 268 surveys were completed, with 66.4% of patients reporting always performing hand hygiene after toileting and 49.2% before eating. The majority of patients (74.6%) stated that they did not want to receive more information about hand hygiene while in the hospital. Key themes identified from 23 interviews include knowledge; environmental context and resources; memory, attention, and decision processes; and social influences.

CONCLUSIONS

Self-reported patient hand hygiene rates are suboptimal and there are knowledge gaps among patients as to when to perform hand hygiene, but patients are not receptive to receiving traditional educational interventions. Future interventions to improve patient hand hygiene should focus on other behavior change domains, including environmental context and resources (eg, access to hand sanitizer at the bedside), memory, attention, and decision processes (eg, posters or other reminders), and social influences (eg, role modeling).

Nurses' knowledge, behaviour and compliance concerning hand hygiene in nursing homes: a cross-sectional mixed-methods study

Background

Effective hand hygiene is one of the most important measures for protecting nursing home residents from nosocomial infections. Infections with multi-resistant bacteria’s, associated with healthcare, is a known problem. The nursing home setting differs from other healthcare environments in individual and organisational factors such as knowledge, behaviour, and attitude to improve hand hygiene and it is therefore difficult to research the influential factors to improve hand hygiene. Studies have shown that increasing knowledge, behaviour and attitudes could enhance hand hygiene compliance in nursing homes. Therefore, it may be important to examine individual and organisational factors that foster improvement of these factors in hand hygiene. We aim to explore these influences of individual and organisational factors of hand hygiene in nursing home staff, with a particular focus on the function of role modelling by nursing managers.

Methods

We conducted a mixed-methods study surveying 165 nurses and interviewing 27 nursing managers from nursing homes in Germany.

Results

Most nurses and nursing managers held the knowledge of effective hand hygiene procedures. Hygiene standards and equipment were all generally available but compliance to standards also depended upon availability in the immediate work area and role modelling. Despite a general awareness of the impact of leadership on staff behaviour, not all nursing managers fully appreciated the impact of their own consistent role modelling regarding hand hygiene behaviours.

Conclusion

These results suggest that improving hand hygiene should focus on strategies that facilitate the provision of hand disinfectant materials in the immediate work area of nurses. In addition, nursing managers should be made aware of the impact of their role model function and they should implement this in daily practice.

Hand hygiene practices among healthcare workers in a newborn unit of a tertiary referral hospital in Kenya

Background:

Health care-associated infection (HCAI) is a significant cause of morbidity and mortality among hospitalised patients, particularly neonates. Compliance with hand hygiene (HH) recommendations is the simplest and most effective measure in preventing this infection.

Objectives:

To determine the HH practices among healthcare workers (HCWs) in the newborn unit of a tertiary referral hospital in Kenya, their knowledge and perceptions regarding HCAI and importance of HH, and barriers to the recommended HH practices.

Methods:

A descriptive cross-sectional study was conducted to evaluate the HCWs’ compliance with the World Health Organization (WHO) ‘5 Moments for Hand Hygiene’ and a structured self-administered questionnaire adopted from the WHO knowledge and perception of HCW questionnaires was used to answer the secondary objectives.

Results:

The overall HH compliance rate was 15%. HCWs were twice more likely to take a HH action ‘after’ than ‘before’ a patient care procedure (odds ratio [OR] = 2.05; 95% confidence interval [CI] = 1.02–4.19; P = 0.03). Nurses and nursing students had statistically significant lower compliance (OR 0.41; 95% CI = 0.18-0.91; p=0.016) and (OR 0.21; 95% CI = 0.06-0.70; p = 0.004) respectively, compared to the doctors. More than half (52%) of the HCWs were unaware of the five moments/indication for HH. Lack of supplies, forgetfulness and use of gloves were the commonly cited barriers to HH compliance.

Discussion:

HH compliance rate among HCWs in the newborn unit of the tertiary referral hospital was very low. The observed and reported barriers to optimal HH compliance demonstrate a necessity for the adoption of the WHO recommended multimodal HH improvement strategy in this unit.

Unhygienic Practices of Health Professionals in Brazilian Public Hospital Restaurants: An Alert to Promote New Policies and Hygiene Practices in the Hospitals

This study aimed to evaluate health professionals’ unhygienic practices and the stages of behaviour change in Brazilian public hospital restaurants. We evaluated all medium/large-sized public hospital restaurants (HRs) from the Brazilian Federal District (n = 9); a representative sample of 128 users). We evaluated the HRs’ physical structures, their consumers’ socio-demographic characteristics, their unhygienic practices, as well as the stages of behavioural change concerning unhygienic practices. All the HRs presented their menus for self-service distribution, so customers entered in lines to serve themselves. All the HRs had hand-wash sinks for customers; 77.8% offered antiseptic liquid soap; 33.3% offered alcohol gel; and 77.8% offered storage for professional accessories before serving food. Almost half (46.8%) of the customers did not sanitise their hands (with water and antiseptic soap and/or use of alcohol gel) immediately before serving, and 24.2% wore professional uniforms at HRs. Almost half (43.5%) of the customers spoke with each other in line while serving their plates and arranged the food on their plates with the serving utensils from the distribution counter. The declaration of behavioural change was inversely associated with the hygiene practices. Almost half of the individuals did not sanitize their hands; however, 90.4% declared “changed behaviour” when this contaminant practice was presented to them. We verified a high percentage of hygiene practices inconsistent with most of the customers´ answers about their stage of behaviour change. Based on the observations of this study, it is necessary for an awareness program to be developed that is focused on customers of HRs in order to reduce unhygienic practices. Also, it is important to promote new policies for proper hygiene practices in hospital restaurants.

'And you'll suddenly realise 'I've not washed my hands': medical students', junior doctors' and medical educators' narratives of hygiene behaviours

OBJECTIVE

Compliance to hygiene behaviours has long been recognised as important in the prevention and control of healthcare associated infections, but medical doctors still display some of the lowest rates of compliance of all healthcare workers. We aim to understand compliance to hygiene behaviours by analysing medical students', junior doctors' and medical educators' narratives of these behaviours to identify their respective attitudes and beliefs around compliance and how these are learnt during training. Such an understanding can inform future interventions to improve compliance targeted to areas of greatest need.

DESIGN

A qualitative study, using narrative interviews (nine focus groups and one individual interview). Data were analysed thematically using inductive framework analysis.

SETTING

Teaching hospitals in the UK.

PARTICIPANTS

Convenience sample of 25 participants: third-year medical students in their first clinical year (n=13), junior doctors (n=6) and medical educators (n=6).

RESULTS

We identified four main themes: (1) knowledge, (2) constraints, (3) role models/culture and (4) hygiene as an added extra. Knowledge varied across participant groups and appeared to influence behaviours; medical students relied on what they have been told by seniors, while medical educators relied on their own knowledge and experience. There was a strong belief that evidence for the effectiveness of good hygiene behaviours is lacking. Furthermore, medical educators' behaviour appears to strongly influence others. Finally, hygiene was predominately viewed as an added extra rather than an integral part of the process.

CONCLUSIONS

Awareness of the evidence around good hygiene needs to be improved at all levels. Medical students and junior doctors should be encouraged to consider why they are asked to perform certain hygiene behaviours in order to improve ownership of those behaviours. Medical educators need to recognise their responsibilities as role models for their junior counterparts, thereby understanding their role in developing the culture of hygiene practices within their clinical domains.

Pilot randomised controlled trial to improve hand hygiene through mindful moments

BACKGROUND

To evaluate the effectiveness of a brief mindfulness intervention on hand hygiene performance and mindful attention for inpatient physician teams.

DESIGN

A pilot, pre-test/post-test randomised controlled mixed methods trial.

SETTING

One academic medical centre in the USA.

PARTICIPANTS

Four internal medicine physician teams consisting of one attending, one resident, two to three interns and up to four medical students.

INTERVENTION

A facilitated, group-based educational discussion on how mindfulness, as practised through mindful hand hygiene, may improve clinical care and practices in the hospital setting.

MAIN OUTCOMES AND MEASURES

The primary outcome was hand hygiene adherence (percentage) for each patient encounter. Other outcomes were observable mindful moments and mindful attention, measured using the Mindfulness Attention Awareness Scale, from baseline to post-intervention, and qualitative evaluation of the intervention.

RESULTS

For attending physicians, hand hygiene adherence increased 14.1% in the intervention group compared with a decrease of 5.7% in the controls (P=0.035). For residents, the comparable figures were 24.7% (intervention) versus 0.2% (control) (P=0.064). For interns, adherence increased 10.0% with the intervention versus 4.2% in the controls (P=0.007). For medical students, adherence improved more in the control group (4.7% intervention vs 7.7% controls; P=0.003). An increase in mindfulness behaviours was observed for the intervention group (3.7%) versus controls (0.9%) (P=0.021). Self-reported mindful attention did not change (P=0.865).

CONCLUSIONS

A brief, education-based mindfulness intervention improved hand hygiene in attending physicians and residents, but not in medical students. The intervention was well-received, increased mindfulness practice, and appears to be a feasible way to introduce mindfulness in the clinical setting. Future work instructing clinicians in mindfulness to improve hand hygiene may prove valuable.

Changing the paradigm: messages for hand hygiene education and audit from cluster analysis

BACKGROUND

Hand hygiene is considered to be the foremost infection prevention measure. How healthcare workers accept and make sense of the hand hygiene message is likely to contribute to the success and sustainability of initiatives to improve performance, which is often poor.

METHODS

A survey of nurses in critical care units in three National Health Service trusts in England was undertaken to explore opinions about hand hygiene, use of alcohol hand rubs, audit with performance feedback, and other key hand-hygiene-related issues. Data were analysed descriptively and subjected to cluster analysis.

RESULTS

Three main clusters of opinion were visualized, each forming a significant group: positive attitudes, pragmatism and scepticism. A smaller cluster suggested possible guilt about ability to perform hand hygiene.

CONCLUSION

Cluster analysis identified previously unsuspected constellations of beliefs about hand hygiene that offer a plausible explanation for behaviour. Healthcare workers might respond to education and audit differently according to these beliefs. Those holding predominantly positive opinions might comply with hand hygiene policy and perform well as infection prevention link nurses and champions. Those holding pragmatic attitudes are likely to respond favourably to the need for professional behaviour and need to protect themselves from infection. Greater persuasion may be needed to encourage those who are sceptical about the importance of hand hygiene to comply with guidelines. Interventions to increase compliance should be sufficiently broad in scope to tackle different beliefs. Alternatively, cluster analysis of hand hygiene beliefs could be used to identify the most effective educational and monitoring strategies for a particular clinical setting.

Barriers, perceptions, and adherence: Hand hygiene in the operating room and endoscopy suite

We examined the perceptions and barriers to nonsurgical scrubbed hand hygiene in the operating room and endoscopy procedure room using 2 anonymous Likert-scale surveys. Results indicated poor role modeling, inconvenience, and the need to monitor hand hygiene and feedback data to providers because of poor self-awareness of hand hygiene practices.

Implementation of the WHO multimodal Hand Hygiene Improvement Strategy in a University Hospital in Central Ethiopia

Background

The burden of health-care associated infections in low-income countries is high. Adequate hand hygiene is considered the most effective measure to reduce the transmission of nosocomial pathogens. We aimed to assess compliance with hand hygiene and perception and knowledge about hand hygiene before and after the implementation of a multimodal hand hygiene campaign designed by the World Health Organization.

Methods

The study was carried out at Asella Teaching Hospital, a university hospital and referral centre for a population of about 3.5 million in Arsi Zone, Central Ethiopia. Compliance with hand hygiene during routine patient care was measured by direct observation before and starting from six weeks after the intervention, which consisted of a four day workshop accompanied by training sessions and the provision of locally produced alcohol-based handrub and posters emphasizing the importance of hand hygiene. A second follow up was conducted three months after handing over project responsibility to the Ethiopian partners. Health-care workers’ perception and knowledge about hand hygiene were assessed before and after the intervention.

Results

At baseline, first, and second follow up we observed a total of 2888, 2865, and 2244 hand hygiene opportunities, respectively. Compliance with hand hygiene was 1.4% at baseline and increased to 11.7% and 13.1% in the first and second follow up, respectively (p < 0.001). The increase in compliance with hand hygiene was consistent across professional categories and all participating wards and was independently associated with the intervention (adjusted odds ratio, 9.18; 95% confidence interval 6.61-12.76; p < 0.001). After the training, locally produced alcohol-based handrub was used in 98.4% of all hand hygiene actions. The median hand hygiene knowledge score overall was 13 (interquartile range 11–15) at baseline and increased to 17 (15–18) after training (p < 0.001). Health-care workers’ perception surveys revealed high appreciation of the different strategy components.

Conclusion

Promotion of hand hygiene is feasible and sustainable in a resource-constrained setting using a multimodal improvement strategy. However, absolute compliance remained low. Strong and long-term commitment by hospital management and health-care workers may be needed for further improvement.

Assessment of an Aggregate-Level Hand Hygiene Monitoring Technology for Measuring Hand Hygiene Performance Among Healthcare Personnel

BACKGROUND

Despite significant advances in technological methods for hand hygiene surveillance, a lack of evidence prohibits comparison of systems to one another or against the current gold standard of direct observation.

OBJECTIVE

To validate a hand hygiene monitoring technology (HHMT) designed to capture hand hygiene behaviors aggregated at the hospital-unit level (GOJO Industries, Akron, OH).

METHODS

Our team followed a rigorous validation approach to assess the sensitivity and positive predictive value (PPV) of an HHMT. A planned path was first used to measure the accuracy of the system when purposefully activated by investigators. Next, behavioral validation was used to quantify accuracy of the system in capturing real-world behaviors.

RESULTS

During the planned path phase, investigators performed 4,872 unique events across 3 distinct hospital buildings varying in size and age since construction. Overall sensitivity across the medical center was 88.7% with a PPV of 99.2%. During the behavioral validation phase, trained direct observers recorded 5,539 unique events across 3 distinct hospital buildings. Overall sensitivity across the medical center was 92.7% and PPV was 84.4%.

CONCLUSION

Objective measures of sensitivity and PPV indicate the promise of the benefit of this and other HHMTs to capture basic behaviors associated with hand hygiene.

Do physicians clean their hands? Insights from a covert observational study

Physicians are notorious for poor hand hygiene (HH) compliance. We wondered if lower performance by physicians compared with other health professionals might reflect differences in the Hawthorne effect. We introduced covert HH observers to see if performance differences between physicians and nurses decreased and to gain further insights into physician HH behaviors. Following training and validation with a hospital HH auditor, 2 students covertly measured HH during clinical rotations. Students rotated off clinical services every week to increase exposure to different providers and minimize risk of exposing the covert observation. We compared covertly measured HH compliance with data from overt observation by hospital auditors during the same time period. Covert observation produced much lower HH compliance than recorded by hospital auditors during the same time period: 50.0% (799/1597) versus 83.7% (2769/3309) (P < 0.0002). The difference in physician compliance between hospital auditors and covert observers was 19.0% (73.2% vs 54.2%); for nurses this difference was much higher at 40.7% (85.8% vs 45.1%) (P < 0.0001). Physician trainees showed markedly better compliance when attending staff cleaned their hands compared with encounters when attending did not (79.5% vs 18.9%; P < 0.0002). Our study suggests that traditional HH audits not only overstate HH performance overall, but can lead to inaccurate inferences about performance by professional groupings due to relative differences in the Hawthorne effect. We suggest that future improvement efforts will rely on more accurate HH monitoring systems and strong attending physician leadership to set an example for trainees.

Perceived versus Observed Patient Safety Measures in a Critical Care Unit from a Teaching Hospital in Southern Colombia

Introduction. Patient safety is an important topic. The purpose of this study is to evaluate the perceived versus observed patient safety measures (PSM) in critically ill patients in a teaching hospital in Latin America. Materials and Methods. The level of perceived patient safety was evaluated with the patient safety hospital survey. Three months later, a qualitative study was conducted, including video recording of procedures, graded according to adherence to PSM. Levels of adherence were scored during patient mobilization (PM), placement of central catheters (PCC), other invasive procedures (OIP), infection control (IC), and endotracheal intubation (ETI). Results. The perceived adherence of PSM in the prestudy survey was considered fair by 89.1% of the ICU staff. After the survey, 829 ICU procedures were video-recorded. Mean observed adherence for fair patient safety measures was 20.8%. Perceived adherence was higher than the real patient safety protocol measures observed in the videos. Conclusion. Perception of PSM was higher than observed in the management of critically ill patients in a teaching hospital in southern Colombia.

Role models in a preventive program for hand eczema among healthcare workers: a qualitative exploration of their main tasks and associated barriers and facilitators

Background

Role models often play a role when implementing guidelines in healthcare. However, little is known about how role models perform their respective roles, or about which factors may hamper or enhance their functioning. The aim of the present study was therefore to investigate how role models perform there role as a part of a multifaceted implementation strategy on the prevention of hand eczema, and to identify barriers and facilitators for the performing of their role.

Methods

The role models were selected to become a role model and received a role model training. All role models worked at a hospital. In total, 19 role models, were interviewed. A topic list was used focussing on how the role models performed their role and what they experienced to be facilitators and barriers for their role. After coding the interviews, the codes were divided into themes.

Results

This study shows that the main tasks perceived by the role models were to raise awareness, to transfer information, to interact with colleagues about hand eczema, to provide material, and to perform coordinating tasks. Barriers and facilitators were whether the role suited the participant, affinity with the topic, and risk perception.

Conclusions

Most role models performed only the tasks they learned during their training. They mentioned a wide range of barriers and facilitators for the performing of their role. To enhance the functioning of the role models, a suggestion would be to select role models by taking into account prior coaching experience.

Mental models: a basic concept for human factors design in infection prevention

Much of the effort devoted to promoting better hand hygiene is based on the belief that poor hand hygiene reflects poor motivation. We argue, however, that automatic unconscious behaviour driven by 'mental models' is an important contributor to what actually happens. Mental models are concepts of reality--imaginary, often blurred, and sometimes unstable. Human beings use them to reduce mental load and free up capacity in the conscious mind to focus on deliberate activities. They are pragmatic solutions to the complexity of life. Knowledge of such mental processes helps healthcare designers and clinicians overcome barriers to behavioural change. This article reviews the concept of mental models and considers how it can be used to improve hand hygiene and patient safety.

Infection control and prevention considerations

Due to the nature of their underlying illness and treatment regimens, cancer patients are at increased risk of infection. Though the advent and widespread use of anti-infective agents has allowed for the application of ever-greater immune-suppressing therapies with successful treatment of infectious complications, prevention of infection remains the primary goal. The evolutionary changes of microorganisms, whereby resistance to anti-infective therapy is increasingly common, have facilitated a paradigm shift in the field of healthcare epidemiology. No longer is the focus on "control" of infection once established in a healthcare environment. Rather, the emphasis is on prevention of infection before it occurs. The most basic tenet of infection prevention, and the cornerstone of all well-designed infection prevention and control programs, is hand hygiene. The hands of healthcare workers provide a common potential source for transmission of infectious agents, and effective decontamination of the hands reduces the risk of transmission of infectious material to other patients. Once infection is suspected or established; however, implementation of effective control strategies is important to limit the spread of infection within a healthcare environment. This chapter outlines the basic tenets of infection prevention, principles of isolation precautions and control measures, and elements for a successful infection control and prevention program.

Performance of aseptic technique during neuraxial analgesia for labor before and after the publication of international guidelines on aseptic technique

Background

Aseptic technique and handwashing have been shown to be important factors in perioperative bacterial transmission, however compliance often remains low despite guidelines and educational programs. Infectious complications of neuraxial (epidural and spinal) anesthesia are severe but fortunately rare. We conducted a survey to assess aseptic technique practices for neuraxial anesthesia in Israel before and after publication of international guidelines (which focused on handwashing, jewelry/watch removal and the wearing of a mask and cap).

Methods

The sampling frame was the general anesthesiology workforce in hospitals selected from each of the four medical faculties in Israel. Data was collected anonymously over one week in each hospital in two periods: April 2006 and September 2009. Most anesthesiologists received the questionnaires at departmental staff meetings and filled them out during these meetings; additionally, a local investigator approached anesthesiologists not present at these staff meetings individually. Primary endpoint questions were: handwashing, removal of wristwatch/jewelry, wearing mask, wearing hat/cap, wearing sterile gown; answering options were: "always", "usually", "rarely" or "never". Primary endpoint for analysis: respondents who both always wash their hands and always wear a mask ("handwash-mask composite") - "always" versus "any other response". We used logistic regression to perform the analysis. Time (2006, 2009) and hospital were included in the analysis as fixed effects.

Results

135/160 (in 2006) and 127/164 (in 2009) anesthesiologists responded to the surveys; response rate 84% and 77% respectively. Respondents constituted 23% of the national anesthesiologist workforce. The main outcome "handwash-mask composite" was significantly increased after guideline publication (33% vs 58%; p = 0.0003). In addition, significant increases were seen for handwashing (37% vs 63%; p = 0.0004), wearing of mask (61% vs 78%; p < 0.0001), hat/cap (53% vs 76%; p = 0.0011) and wearing sterile gown (32% vs 51%; p < 0.0001). An apparent improvement in aseptic technique from 2006 to 2009 is noted across all hospitals and all physician groups.

Conclusion

Self-reported aseptic technique by Israeli anesthesiologists improved in the survey conducted after the publication of international guidelines. Although the before-after study design cannot prove a cause-effect relationship, it does show an association between the publication of international guidelines and significant improvement in self-reported aseptic technique.

Strategies to minimize antibiotic resistance

Antibiotic resistance can be reduced by using antibiotics prudently based on guidelines of antimicrobial stewardship programs (ASPs) and various data such as pharmacokinetic (PK) and pharmacodynamic (PD) properties of antibiotics, diagnostic testing, antimicrobial susceptibility testing (AST), clinical response, and effects on the microbiota, as well as by new antibiotic developments. The controlled use of antibiotics in food animals is another cornerstone among efforts to reduce antibiotic resistance. All major resistance-control strategies recommend education for patients, children (e.g., through schools and day care), the public, and relevant healthcare professionals (e.g., primary-care physicians, pharmacists, and medical students) regarding unique features of bacterial infections and antibiotics, prudent antibiotic prescribing as a positive construct, and personal hygiene (e.g., handwashing). The problem of antibiotic resistance can be minimized only by concerted efforts of all members of society for ensuring the continued efficiency of antibiotics.

Types of interventions used to improve hand hygiene compliance and prevent healthcare associated infection

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.

Relationship between systems-level factors and hand hygiene adherence

This study was a cross-sectional descriptive survey of acute care hospitals in California to describe staff hand hygiene compliance and related predictors and explore the relationship between hand hygiene adherence and health care-associated infections. Although there was a relatively small sample size, institutions with morning huddles reported a significantly higher proportion of 95% or more hand hygiene compliance. Huddles are an organizational tool to improve teamwork and communication and may offer promise to influence hand hygiene adherence.

Influencing controlled substance prescribing: attending and resident physician use of a state prescription monitoring program

OBJECTIVE

The purpose of this study is to evaluate the influence of attending physician awareness and utilization of a state prescription monitoring program on resident physician behavior.

DESIGN

Twenty-five attending physicians and 70 residents in Emergency Medicine, Internal Medicine, Neurology, Pediatrics, and Psychiatry completed an 11-item questionnaire assessing awareness and utilization of a state prescription drug monitoring program.

RESULTS

Residents who used the system had, on average, a higher proportion of supervising attendings using the system; residents required to utilize the system had the highest proportion of attendings using the system. Overall, almost 90% of the physicians who utilized the system did so due to concerns surrounding prescription drug abuse. Over one third of attending physicians reported increasing the quantity or amount of medication prescribed after utilizing the system, while no residents reported similar outcomes. Through the behavioral influence of supervising attending physicians, residents were significantly more likely to utilize the system. If system utilization is desired, attendings should use the system and require resident participation.

Bundling hand hygiene interventions and measurement to decrease health care-associated infections

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

Tuberculosis infection control in a high drug-resistance setting in rural South Africa: information, motivation, and behavioral skills

BACKGROUND

Tuberculosis (TB) is transmitted in resource-limited facilities where TB infection control (IC) is poorly implemented. Theory-based behavioral models can potentially improve IC practices.

METHODS

The present study used an anonymous questionnaire to assess healthcare worker (HCW) TB IC information, motivation, and behavioral skills (IMB) and implementation in two resource-limited rural South African hospitals with prevalent drug-resistant TB.

RESULTS

Between June and August 2010, 198 surveys were completed. Although the respondents demonstrated information proficiency and positive motivation, 22.8% did not consider TB IC to be worthwhile. Most tasks were rated as easy by survey participants, but responding HCWs highlighted challenges in discrete behavioral skills. The majority of responding HCWs reported that they always wore respirators (54.3%), instructed patients on cough hygiene (63.0%), and ensured natural ventilation (67.4%) in high-risk areas. Most respondents (74.0%) knew their HIV status. Social support items correlated with the implementation of the first three aforementioned practices but not with the respondents' knowledge of their HIV status. In most cases, motivation and behavioral skills, but not information, were associated with implementation.

CONCLUSION

HCWs in rural South African hospitals with high drug-resistance demonstrated moderate IMB and implementation of TB IC. Improvement efforts should emphasize the development of HCW motivation and behavioral skills as well as social support from colleagues and supervisors. Such interventions should be informed by baseline IMB assessments. In the present study, a trimmed/modified IMB model helped characterize TB IC implementation.

Hand hygiene: back to the basics of infection control

Health care associated infections are drawing increasing attention from patients, insurers, governments and regulatory bodies. This is not only because of the magnitude of the problem in terms of the associated morbidity, mortality and cost of treatment, but also due to the growing recognition that most of these are preventable. The medical community is witnessing in tandem unprecedented advancements in the understanding of pathophysiology of infectious diseases and the global spread of multi-drug resistant infections in health care set-ups. These factors, compounded by the paucity of availability of new antimicrobials have necessitated a re-look into the role of basic practices of infection prevention in modern day health care. There is now undisputed evidence that strict adherence to hand hygiene reduces the risk of cross-transmission of infections. With "Clean Care is Safer Care" as a prime agenda of the global initiative of WHO on patient safety programmes, it is time for developing countries to formulate the much-needed policies for implementation of basic infection prevention practices in health care set-ups. This review focuses on one of the simplest, low cost but least accepted from infection prevention: hand hygiene.

Adequacy of dialysis clinic staffing and quality of care: a review of evidence and areas of needed research

Improving the quality of care delivered to patients receiving in-center dialysis treatment remains a perpetual concern with stakeholders. Quality indicators traditionally have focused on such items as adequacy of dialysis, anemia management, patient survival, and, most recently, the percentage using arteriovenous fistulas. Largely overlooked in the quest for improvement has been adequate consideration of dialysis clinic staffing levels. Staffing is important because it has been identified as a structural measure of quality. With 326,671 (93.1%) of all dialysis patients receiving in-center treatments, this is a potentially critical issue. This article reviews evidence related to inadequacies in clinic staffing and how they may be contributing to suboptimal care and outcomes. Focusing on nephrologists, nurses, patient care technicians, dietitians, and social workers, this article suggests areas of needed research.

Twenty-four-hour observational study of hospital hand hygiene compliance

This observational study measured healthcare workers' (HCWs'), patients' and visitors' hand hygiene compliance over a 24h period in two hospital wards using the 'five moments of hand hygiene' observation tool. Hand hygiene is considered to be the most effective measure in reducing healthcare-associated infections but studies have reported suboptimal levels of compliance. Most studies have used random observational time-periods for data collection and this has been criticised. We monitored a total of 823 hand hygiene opportunities (HCWs, N=659; patients and visitors, N=164). Among HCWs, compliance was 47% for doctors, 75% for nurses, 78% for allied health professionals, and 59% for ancillary and other staff (P<0.001). There was no difference in compliance between patients and visitors (56% vs 57%, P=0.87). Hand hygiene compliance varied depending on which of the five moments of hygiene HCWs had undertaken (P<0.001), with compliance before an aseptic task being 100% (3/3); after body fluid exposure 93% (86/93); after patient contact 80% (114/142); before patient contact 68% (196/290); and after contact with surroundings 50% (65/129). Lower levels of compliance were found for HCWs working during the early shift (P<0.001). For patients and visitors there was no evidence of an association between moments of hygiene and compliance. Levels of compliance were higher compared with previous reported estimates. Medical staff had the lowest level of compliance and this continues to be a concern which warrants specific future interventions.

Interventions to improve hand hygiene compliance in patient care

BACKGROUND

Health care-associated infection is a major cause of morbidity and mortality. Hand hygiene is regarded as an effective preventive measure.

OBJECTIVES

To update the review done in 2007, to assess the short and longer-term success of strategies to improve hand hygiene compliance and to determine whether a sustained increase in hand hygiene compliance can reduce rates of health care-associated infection.

SEARCH STRATEGY

We conducted electronic searches of: the Cochrane Central Register of Controlled Trials; the Cochrane Effective Practice and Organisation of Care Group specialised register of trials; MEDLINE; PubMed; EMBASE; CINAHL; and the BNI. Originally searched to July 2006, for the update databases were searched from August 2006 until November 2009.

SELECTION CRITERIA

Randomised controlled trials, controlled clinical trials, controlled before and after studies, and interrupted time series analyses meeting explicit entry and quality criteria used by the Cochrane Effective Practice and Organisation of Care Group were eligible for inclusion. Studies reporting indicators of hand hygiene compliance and proxy indicators such as product use were considered. Self-reported data were not considered a valid measure of compliance. Studies to promote hand hygiene compliance as part of a care bundle approach were included, providing data relating specifically to hand hygiene were presented separately. Studies were excluded if hand hygiene was assessed in simulations, non-clinical settings or the operating theatre setting.

DATA COLLECTION AND ANALYSIS

Two reviewers independently extracted data and assessed data quality.

MAIN RESULTS

Four studies met the criteria for the review: two from the original review and two from the update. Two studies evaluated simple education initiatives, one using a randomized clinical trial design and the other a controlled before and after design. Both measured hand hygiene compliance by direct observation. The other two studies were both interrupted times series studies. One study presented three separate interventions within the same paper: simple substitutions of product and two multifaceted campaigns, one of which included involving practitioners in making decisions about choice of hand hygiene products and the components of the hand hygiene program. The other study also presented two separate multifaceted campaigns, one of which involved application of social marketing theory. In these two studies follow-up data collection continued beyond twelve months, and a proxy measure of hand hygiene compliance (product use) was recorded. Microbiological data were recorded in one study. Hand hygiene compliance increased for one of the studies where it was measured by direct observation, but the results from the other study were not conclusive. Product use increased in the two studies in which it was reported, with inconsistent results reported for one initiative. MRSA incidence decreased in the one study reporting microbiological data.

AUTHORS' CONCLUSIONS

The quality of intervention studies intended to increase hand hygiene compliance remains disappointing. Although multifaceted campaigns with social marketing or staff involvement appear to have an effect, there is insufficient evidence to draw a firm conclusion. There remains an urgent need to undertake methodologically robust research to explore the effectiveness of soundly designed and implemented interventions to increase hand hygiene compliance.
