Improving hand hygiene compliance in health care workers: Strategies and impact on patient outcomes

Effectiveness of sensing gloves-applied virtual reality education system on hand hygiene practice: A randomized controlled trial

BACKGROUND

We developed a virtual reality (VR) education system and evaluated its clinical utility for promoting hand hygiene practices.

METHODS

This prospective, 2-week, randomized controlled study conducted at Okayama University Hospital, Japan, from November 2023 to January 2024, involved 22 participants (18 medical students and 4 residents). A fully immersive 360° VR system (VIVE Pro Eye) using a head-mounted display and sensing gloves was used to develop 3 health care tasks in a virtual patient room-Environmental Cleaning, Gauze Exchange, and Urine Collection. After monitoring all participants' baseline usage data of portable hand-rubbing alcohol in the first week, we randomly assigned them into 1:1 groups (VR training and video lecture groups). The primary outcome was differences in hand-rubbed alcohol use before and after intervention.

RESULTS

Before the intervention, alcohol use did not significantly differ between both groups. After the intervention, a significant increase in alcohol use was observed in the VR training group (median: 8.2 g vs 16.2 g; P = .019) but not in the video lecture group.

CONCLUSIONS

Our immersive 360° VR education system enhanced hand hygiene practices. Infection prevention and control practitioners and digital technology experts must collaborate to advance the development of superior educational devices and content.

Digital Maturity as a Predictor of Quality and Safety Outcomes in US Hospitals: Cross-Sectional Observational Study

BACKGROUND

This study demonstrates that digital maturity contributes to strengthened quality and safety performance outcomes in US hospitals. Advanced digital maturity is associated with more digitally enabled work environments with automated flow of data across information systems to enable clinicians and leaders to track quality and safety outcomes. This research illustrates that an advanced digitally enabled workforce is associated with strong safety leadership and culture and better patient health and safety outcomes.

OBJECTIVE

This study aimed to examine the relationship between digital maturity and quality and safety outcomes in US hospitals.

METHODS

The data sources were hospital safety letter grades as well as quality and safety scores on a continuous scale published by The Leapfrog Group. We used the digital maturity level (measured using the Electronic Medical Record Assessment Model [EMRAM]) of 1026 US hospitals. This was a cross-sectional, observational study. Logistic, linear, and Tweedie regression analyses were used to explore the relationships among The Leapfrog Group's Hospital Safety Grades, individual Leapfrog safety scores, and digital maturity levels classified as advanced or fully developed digital maturity (EMRAM levels 6 and 7) or underdeveloped maturity (EMRAM level 0). Digital maturity was a predictor while controlling for hospital characteristics including teaching status, urban or rural location, hospital size measured by number of beds, whether the hospital was a referral center, and type of hospital ownership as confounding variables. Hospitals were divided into the following 2 groups to compare safety and quality outcomes: hospitals that were digitally advanced and hospitals with underdeveloped digital maturity. Data from The Leapfrog Group's Hospital Safety Grades report published in spring 2019 were matched to the hospitals with completed EMRAM assessments in 2019. Hospital characteristics such as number of hospital beds were obtained from the CMS database.

RESULTS

The results revealed that the odds of achieving a higher Leapfrog Group Hospital Safety Grade was statistically significantly higher, by 3.25 times, for hospitals with advanced digital maturity (EMRAM maturity of 6 or 7; odds ratio 3.25, 95% CI 2.33-4.55).

CONCLUSIONS

Hospitals with advanced digital maturity had statistically significantly reduced infection rates, reduced adverse events, and improved surgical safety outcomes. The study findings suggest a significant difference in quality and safety outcomes among hospitals with advanced digital maturity compared with hospitals with underdeveloped digital maturity.

Challenges of accessing hygiene facilities when on the move: an exploratory interview study with UK mobile workers

BACKGROUND

Access to hygiene facilities is essential for health and well-being, and in many countries, employers are legally obliged to ensure that hygiene facilities are readily available. This interview study considers how being on the move impacts the ability of mobile workers (such as community care workers, police, delivery drivers, gardeners, cleaners, utility workers) to access hygiene facilities, and the challenges they face.

METHODS

Using a qualitative exploratory research design, we investigate through semi-structured interviews with 22 United Kingdom (UK) mobile workers (1) what influences their access to hygiene facilities, (2) their hygiene needs, and (3) where mobile workers are accessing hygiene facilities. The interview data was analysed qualitatively using a coding framework developed from a literature review of hand hygiene in fixed workplaces.

RESULTS

Mobile workers' access to hygiene facilities is influenced by the wider cultural environment, the biological environment, the organisational environment, the physical environment, the facility owner, the worker's role, and the individual themselves, all underpinned by social norms. Our participants needed hygiene facilities so they could use the toilet, clean themselves, and do their work, and for First Aid. Access to facilities is challenging, and our participants needed to access facilities where they were working, travel to find them, or use hygiene kits. The quality of facilities is frequently poor, and mobile workers must often seek permission and may incur financial costs. Our participants often had to rely on the goodwill of people in private homes. In the absence of facilities, workers often resort to strategies that may affect their health (such as restricting drinking and eating, and ignoring urges) or their dignity (such as relieving themselves outdoors or even soiling their clothes).

CONCLUSIONS

The lack of hygiene facilities available to mobile workers is a serious health and well-being concern. Given that there are many occupations where workers are mobile at least some of the time, the scale of the problem needs to be recognised. This study adds to our understanding of hygiene in workplaces and highlights the inadequacy of current legislation, which appears to serve primarily those working in fixed workplaces such as offices. Recommendations are made to policy makers and organisations.

Infection prevention and control: a guide for community nurses

The onset of the COVID-19 pandemic highlighted the importance of infection prevention and control (IPC), and accentuated the need for better health and safety measures to protect both healthcare professionals and their patients. In this article, Francesca Ramadan provides an overview of IPC measures for community nurses, such as hand hygiene and personal protective equipment, along with the safe management of care equipment and the care environment.

Development and evaluation of an ultra-wide bandwidth based electronic hand hygiene monitoring system

BACKGROUND

A large variety of electronic hand hygiene monitoring systems (EHHMS) are being developed and applied in health care settings. Monitoring hand hygiene (HH) opportunity at bed-level has been the key technical challenge. Accuracy evaluation needs more attention as the prerequisite upon widespread acceptance and adoption.

METHODS

For the first time, we explored, debugged and upgraded an EHHMS based on ultra-wide bandwidth (UWB) which can obtain HH opportunities at bed-level. The real-time positioning and electronic fence of UWB technology was applied for EHHMS. The accuracy of EHHMS was compared with the simultaneous manual direct observations in real-world clinical setting. Sensitivity and specificity were calculated for EHHMS capturing HH action and opportunity.

RESULTS

Two generations of EHHMS were constructed. For the first generation, the system properly recorded 84% and 78% of the pre-identified HH actions and opportunities performed by experimenters. For the second generation, sensitivity and specificity of the system capturing HH action were 89% (84.83-92.36) and 100% (98.26-100.00), respectively. For capturing HH opportunity, the system showed the sensitivity and specificity of 86.52% (82.52-89.89) and 88.10% (84.14-91.36)), respectively.

CONCLUSION

The EHHMS based on UWB could accurately identify HH action and opportunity with equivalent accuracy compared with simultaneous direct observation.

Virtual reality as a learning tool for improving infection control procedures

BACKGROUND

Hand hygiene and donning personal protective equipment (PPE) are essential techniques for infection control; however, low compliance is an issue. The effectiveness of virtual reality (VR) in learning infection control procedures is unknown.

METHODS

To verify the effectiveness of VR, medical students were categorized into VR or lecture groups (n=21 each). Each group was given the same curricular content; one group received the training through VR learning using a fully-immersive 360-degree video and the other was conventional lecture-style learning. Before and after the training, they were evaluated for the implementation of hand hygiene and PPE using an Objective Structured Clinical Examination method. Post-test questionnaires were administered.

RESULTS

The scores for hand hygiene, donning PPE, and the total score increased after learning in both groups. There was no difference between the pre-test total scores of the two groups (7 [5-9] vs 6 [5-7.5], P=.352); however, the VR group had significantly higher post-test total scores than the lecture group (12 [9.5-12] vs 9 [8-12], P=.024). More students in the VR group responded that they enjoyed the training and would like to use the same learning method next time.

CONCLUSIONS

VR can be a useful tool for learning and practicing appropriate infection control procedures.

Hand hygiene compliance by direct observation in physicians and nurses: a systematic review and meta-analysis

BACKGROUND

Direct observation of hand hygiene compliance is the "gold standard" despite limitations and potential for bias. Previous literature highlights poorer hand hygiene compliance amongst physicians than nurses and suggests that covert monitoring may give better compliance estimates than overt monitoring.

AIM

This review aimed to explore differences in compliance between physicians and nurses further, and to analyse if compliance estimates differed when observations were covert rather than overt.

METHODS

A systematic search of databases PubMed, EMBASE, CENTRAL and CINAHL was performed. Experimental or observational studies in hospital settings in high-income countries published in English from 2010 onwards were included if estimates for both physicians and nurses using direct observation were reported. The search yielded 4814 studies, of which 105 were included.

FINDINGS

The weighted pooled compliance rate for nurses was 52% (95% CI 47% to 57%) and for doctors was 45% (95% CI 40% to 49%). Heterogeneity was considerable (I²=99%). The majority of studies were at moderate or high risk of bias. Random-effects meta-analysis of low risk of bias studies suggests higher compliance for nurses than physicians for both overt (difference of 7%, 95% CI for the difference 0.8% to 13.5%, p=0.027) and covert (difference of 7%, 95% CI 3% to 11%, p=0.0002) observation. Considerable heterogeneity was found in all analyses.

CONCLUSION

Wide variability in compliance estimates and differences in the methodological quality of hand hygiene studies were identified. Further research with meta-regression should explore sources of heterogeneity and improve the conduct and reporting of hand hygiene studies.

Discordance among Belief, Practice, and the Literature in Infection Prevention in the NICU

This study evaluates practices of infection control in the NICU as compared with the available literature. We aimed to assess providers’ awareness of their institutional policies, how strongly they believed in those policies, the correlation between institution size and policies adopted, years of experience and belief in a policy’s efficacy, and methods employed in the existing literature. An IRB-approved survey was distributed to members of the AAP Neonatal Section. A systematic review of the literature provided the domains of the survey questions. Data was analyzed as appropriate. A total of 364 providers responded. While larger NICUs were more likely to have policies, their providers are less likely to know them. When a policy is in place and it is known, providers believe in the effectiveness of that policy suggesting consensus or, at its worst, groupthink. Ultimately, practice across the US is non-uniform and policies are not always consistent with best available literature. The strength of available literature is adequate enough to provide grade B recommendations in many aspects of infection prevention. A more standardized approach to infection prevention in the NICU would be beneficial and is needed.

A Quality Improvement Initiative to Increase Hand Hygiene Awareness and Compliance in a Neonatal Intensive Care Unit in Haiti

INTRODUCTION

Healthcare-associated infections (HCAI) are major causes of morbidity, mortality, increased lengths of stay and are an economic burden on healthcare systems in resources-limited settings. This is especially true for neonates, who are more susceptible with underdeveloped immune systems. Hand hygiene (HH) is a key weapon against HCAI, yet globally, HH compliance remains substandard. This study sought to determine the compliance with HH among healthcare workers (HCWs) in a children's hospital neonatal intensive care unit (NICU) in Haiti.

METHODS

A HH educational intervention was performed in the NICU, including lectures and posters. Pre- and post-intervention HH data were collected on HCWs and parents using the World Health Organization '5 Moments for HH'. Data were analyzed using standard statistical analysis.

RESULTS

HH increased in all HCW roles but not in parents. Correct HH increased in all groups, including parents. HH was more likely to occur prior to patient contact than after patient contact. Correct HH was more likely to occur with alcohol-based hand rub than with soap and water.

CONCLUSION

This study demonstrates that an inexpensive and simple intervention can significantly increase HH compliance in a resource-limited NICU, which may lead to decreased rates of hospital-acquired sepsis. Parents, however, due to cultural norms as well as literacy and language barriers, need targeted educational interventions distinct from those that HCW benefit from.

Paediatric nurses', children's and parents' adherence to infection prevention and control and knowledge of antimicrobial stewardship: A systematic review

INTRODUCTION

Infection prevention and control precautions help to decrease microbial transmission, and through the appropriate use of antibiotics, Antimicrobial Stewardship programs aim to decrease the prevalence and emergence of Antimicrobial Resistance.

METHODS

A systematic review was undertaken to critically appraise and synthesise evidence for nurses', children's and parents' knowledge and understanding of antimicrobial stewardship, and of infection prevention and control in acute paediatric care settings. The Preferred Reporting Items for Systematic reviews and Meta-Analyses guided the review. Studies were included if they examined the factors that contributed to nurses' adherence to, or consumers' practice in relation to, antimicrobial stewardship and infection prevention and control.

RESULTS

Of the 16,957 papers identified, 50 studies conducted in acute paediatric settings met the eligibility criteria, and were included. Most studies were of low methodological quality. Fourteen studies evaluated nurses' knowledge and self-reported adherence to Infection Prevention and Control principles and identified consistent practice gaps by nurses. Six studies evaluating the effectiveness of education programs reported modest improvements in nurses' knowledge and adherence to infection prevention and control. There were 15 studies, that investigated consumers' involvement in infection prevention and control that identified the following themes: Consumer knowledge and attitudes to infection prevention and control and transmission-based precautions, and parents' willingness to take an active role in infection prevention. Six studies focused on paediatric nurses' role in antimicrobial stewardship, exploring the following themes: (1) nurses' understanding and beliefs of antimicrobial stewardship roles, and (2) barriers to nurses taking a greater role in antimicrobial stewardship. Nine studies explored the role of consumers in antimicrobial stewardship and identified consumers' misconceptions about the benefits and downplayed concerns regarding antibiotic use.

DISCUSSION

Although consumers articulated a willingness to be actively involved in infection prevention, observed practice remained lower than that required to consistently prevent infection transmission.

CONCLUSION

These findings highlight a critically important gap in current practice. In relation to optimal use of antimicrobials, although paediatric nurses were involved in supporting antimicrobial stewardship processes and educating consumers, they identified limited antimicrobial stewardship knowledge. Consumers appeared to lack understanding about the benefits of antibiotics and negated concerns regarding antibiotic use.

Prevalence, Characteristics, and Epidemiology of Microbial Hand Contamination Among Minnesota State Fair Attendees (2014)

Background: Many antimicrobial-resistant infections are community-acquired, yet community carriage of microorganisms by healthy individuals is poorly characterized. We assessed microorganism carriage on the hands of Minnesota State Fair attendees and explored associated factors.

Methods: Minnesota State Fair attendees (in 2014) from households with ≥2 members (≥1 member being <19 years old [a child]) were eligible to participate. Participants provided biological samples via a hand plating technique and completed a questionnaire on factors potentially related to microorganism carriage. Using presumptive taxonomic identifications and disk-diffusion-determined resistance phenotypes, hand-culture isolates were classified by microbial type; types were grouped into four broad categories based on inferred pathogenicity and consistency with the skin microbiota. Descriptive statistics, X² tests, and generalized linear mixed-effects models were used to explore associations between survey and culture data.

Results: We enrolled 206 participants from 82 households during 2 days; 50% of subjects were children. Overall, 99.5% (205/206) of hand samples yielded microorganisms. Most were non-pathogenic, whether skin microbiota (98.5% of participants) or non-skin microbiota (93.2% of participants). Only 2.4% (5/206) of samples yielded antibiotic-resistant bacteria. Children were more likely than adults to carry potentially pathogenic (OR = 3.63, 95% CI: 1.66–7.93) and presumably non-pathogenic (OR = 6.61, 95% CI: 1.67–26.15) non-skin microorganisms.

Conclusions: Large community gatherings can serve as efficient sites for estimating the prevalence of microorganism carriage. A small proportion of participants carried antimicrobial-resistant pathogens on their hands; most carried non-pathogenic microorganisms, and no exposures specific to the state fair were associated with microorganism carriage.

Virucidal activity of three ethanol-based hand rubs against murine norovirus in a hand hygiene clinical simulation study

Aim: We evaluated the efficacy of three ethanol-based hand rubs against murine norovirus in a proposed clinical simulation test (prEN 17430). Materials & methods: Virucidal activity was determined in 18 volunteers using three hand rubs: ethanol 72.4 and 89.5% v/v solutions, and 86% v/v gel. Subjects underwent testing with each product (3/6 ml for 15/30 s) and a reference solution (6 ml 70% v/v ethanol for 60 s). Results: Against murine norovirus, the reduction factors (RF; RF mean ± standard deviation log₁₀ reduction of postsampling) for ethanol gel 86% v/v (RF 1.96 ± 0.64), ethanol 89.5% v/v (RF 2.49 ± 0.59) and ethanol 72.4% v/v (RF 2.61 ± 0.50), were all significantly superior to that of the reference solution. Conclusion: All three hand rubs passed the criteria set out in prEN 17430 and exhibited excellent virucidal efficacy.

Handrubbing with sprayed alcohol-based hand rub: an alternative method for effective hand hygiene

BACKGROUND

Hand hygiene is crucial in infection prevention and control. It is unclear whether sprayed alcohol-based hand rub (ABHR) is non-inferior to the World Health Organization (WHO)-recommended method of handrubbing with poured ABHR.

AIM

To test whether sprayed ABHR can be an alternative (non-inferior) method for effective hand hygiene with/without handrubbing.

METHODS

A laboratory experiment was conducted with ABHR (isopropanol 60% v/v) according to European Norm 1500. Hand hygiene was performed by: (1) handrubbing with ABHR poured on to the palm of the hand; (2) handrubbing with sprayed ABHR; and (3) applying sprayed ABHR to hands without handrubbing. Hands were contaminated with Escherichia coli ATCC 10536, followed by hand hygiene and microbiological sampling. A generalized linear mixed model with a random intercept per subject was used to analyse the reduction in bacterial count following hand hygiene.

FINDINGS

In total, 19 healthcare workers participated in the study. Handrubbing with sprayed ABHR was non-inferior [margin log₁₀ 0.6 colony-forming units (cfu)/mL] to the WHO-recommended method of handrubbing with poured ABHR; bacterial count reductions were log₁₀ 3.66 cfu/mL [95% confidence interval (CI) 1.68-5.64] and log₁₀ 3.46 cfu/mL (95% CI 1.27-5.65), respectively. Conversely, non-inferiority was not found for sprayed ABHR without handrubbing [bacterial count reduction log₁₀ 2.76 cfu/mL (95% CI 1.65-3.87)].

CONCLUSION

Handrubbing with sprayed ABHR was non-inferior to handrubbing with ABHR poured on to the palm of the hand to reduce bacterial counts on hands under experimental conditions. Handrubbing with sprayed ABHR may be an acceptable alternative hand hygiene method pending assessment in other settings and for other pathogens.

Addressing Hand Hygiene Compliance in a Low-Resource Neonatal Intensive Care Unit: a Quality Improvement Project

OBJECTIVE

Our goal for this study was to quantify healthcare provider compliance with hand hygiene protocols and develop a conceptual framework for increasing hand hygiene compliance in a low-resource neonatal intensive care unit.

MATERIALS AND METHODS

We developed a 3-phase intervention that involved departmental discussion, audit, and follow-up action. A 4-month unobtrusive audit during night and day shifts was performed. The audit results were presented, and a conceptual framework of barriers to and solutions for increasing hand hygiene compliance was developed collectively.

RESULTS

A total of 1308 hand hygiene opportunities were observed. Among 1227 planned patient contacts, hand-washing events (707 [58.6%]), hand rub events (442 [36%]), and missed hand hygiene (78 [6.4%]) events were observed. The missed hand hygiene rate was 20% during resuscitation. Missed hand hygiene opportunities occurred 3.2 times (95% confidence interval, 1.9-5.3 times) more often during resuscitation procedures than during planned contact and 6.14 times (95% confidence interval, 2.36-16.01 times) more often when providers moved between patients. Structural and process determinants of hand hygiene noncompliance were identified through a root-cause analysis in which all members of the neonatal intensive care unit team participated. The mean hand-washing duration was 40 seconds. In 83% of cases, drying hands after washing was neglected. Hand recontamination after hand-washing was seen in 77% of the cases. Washing up to elbow level was observed in 27% of hand-wash events. After departmental review of the study results, hand rubs were placed at each bassinet to address these missed opportunities.

CONCLUSIONS

Hand hygiene was suboptimal during resuscitation procedures and between patient contacts. We developed a conceptual framework for improving hand hygiene through a root-cause analysis.

Evaluating the effectiveness of the "Germ-Free Hands" intervention for improving the hand hygiene practices of public health students

PURPOSE

This quasi-experimental study sought to assess the effectiveness of a multidisciplinary intervention called "Germ-Free Hands" to improve the hand hygiene practices of students attending Thailand's Sirindhorn College of Public Health (SCPH).

METHODS

The intervention was developed and implemented at SCPH and incorporated education, training, a workshop, and performance feedback. The intervention targeted behavioral antecedents specified by the Health Belief Model (HBM) and the Theory of Planned Behavior (TPB). Handwashing determinants (knowledge, beliefs, attitudes, subjective norms, perceived behavioral control, and intentions) and hand hygiene behaviors were assessed at baseline, immediately post-intervention, and 3 months post-intervention for the intervention group at (n=60) at the Suphanburi campus of SCPH and a matched control group (n=60) of students at the Ubonratchathani campus. Data analysis included descriptive statistics, independent samples t-tests, two-way measures of analysis of variance, and a generalized estimating equation to compare handwashing practices by self-reports between two groups.

RESULTS

The "Germ-Free Hands" intervention produced significant improvements in the intervention group's handwashing knowledge, behavioral and control beliefs, subjective norm scores, intentions, and behaviors, as compared to the control group. However, the intervention had no significant impact on normative beliefs, attitudes, or perceived behavioral control. Reported improvements also decreased 3 months post-intervention, and the number of bacterial colonies on students' hands increased over the course of the study.

CONCLUSION

This study adds to the evidence that multidisciplinary interventions can be effective at improving handwashing rates. However, education and training must be continuous, rather than delivered as a one-time program, in order to have sustained results. Participants may also require more in-depth instruction in correct handwashing and drying techniques to remove bacteria effectively and prevent recolonization.

Effectiveness over time of a multimodal intervention to improve compliance with standard hygiene precautions in an intensive care unit of a large teaching hospital

Background

Standard hygiene precautions are an effective way of controlling healthcare-associated infections. Nevertheless, compliance with hand hygiene (HH) guidelines among healthcare workers (HCWs) is often poor, and evidence regarding appropriate use of gloves and gowns is limited and not encouraging. In this study, we evaluated the ability over time of a multimodal intervention to improve HCWs compliance with standard hygiene precautions.

Methods

Trend analysis of direct observations of compliance with HH guidelines and proper glove or gown use was conducted in the medical/surgical intensive care unit (ICU) of Umberto I Teaching Hospital of Sapienza University of Rome. The study consisted of two phases: a six-month baseline phase and a 12-month post-intervention phase. The multimodal intervention was based on the World Health Organization strategy and included education and training of HCWs, together with performance feedback.

Results

A total of 12,853 observations were collected from November 2016 to April 2018. Overall compliance significantly improved from 41.9% at baseline to 62.1% (p < 0.001) after the intervention and this improvement was sustained over the following trimesters. Despite variability across job categories and over the study period, a similar trend was observed for most investigations. The main determinants of compliance were job category (with nurses having the highest compliance rates), being a member of ICU staff and whether delivering routine, as opposed to emergency, care. HH compliance was modified by glove use; unnecessary gloving negatively affected HH behaviour while appropriate gloving positively influenced it.

Conclusions

The multimodal intervention resulted in a significant improvement in compliance with standard hygiene precautions. However, regular educational reinforcement and feedback is essential to maintain a high and uniform level of compliance.

Using targeted solution tools as an initiative to improve hand hygiene: challenges and lessons learned

The Joint Commission Centre for Transforming Healthcare's Web-based Targeted Solutions Tool (TST) for improving hand hygiene was implemented to elucidate contributing factors to low compliance rates of hand hygiene. Monitoring of compliance was done by trained unknown and known observers and rates of hospital-acquired infections were tracked and correlated against the changes in hand hygiene compliance. In total, 5669 of hand hygiene observations were recorded by the secret observers. The compliance rate increased from 75·4% at baseline (May-August 2014) to 88·6% during the intervention (13 months) and the control periods (P < 0·0001). Reductions in healthcare-associated infection rates were recorded for Clostridium difficle infections from 7·95 (CI 0·8937-28·72) to 1·84 (CI 0·02411-10·26) infections per 10 000 patient-days (P = 0·23), central line-associated blood-stream infections from 5·9 (CI 1·194-17·36) to 2·9 (0·7856-7·475) per 1000 device days (P = 0·37) and catheter-associated urinary tract infections from 5·941 (CI 1·194-17·36) to 0 per 1000 device days (P = 0·42). The top contributing factors for non-compliance were: improper use of gloves, hands full of supplies or medications and frequent entry or exit in isolation areas. We conclude that the application of TST allows healthcare organisations to improve hand hygiene compliance and to identify the factors contributing to non-compliance.

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. This is an update of a previously published review.

OBJECTIVES

To assess the short- and long-term success of strategies to improve compliance to recommendations for hand hygiene, and to determine whether an increase in hand hygiene compliance can reduce rates of health care-associated infection.

SEARCH METHODS

We conducted electronic searches of the Cochrane Register of Controlled Trials, PubMed, Embase, and CINAHL. We conducted the searches from November 2009 to October 2016.

SELECTION CRITERIA

We included randomised trials, non-randomised trials, controlled before-after studies, and interrupted time series analyses (ITS) that evaluated any intervention to improve compliance with hand hygiene using soap and water or alcohol-based hand rub (ABHR), or both.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened citations for inclusion, extracted data, and assessed risks of bias for each included study. Meta-analysis was not possible, as there was substantial heterogeneity across studies. We assessed the certainty of evidence using the GRADE approach and present the results narratively in a 'Summary of findings' table.

MAIN RESULTS

This review includes 26 studies: 14 randomised trials, two non-randomised trials and 10 ITS studies. Most studies were conducted in hospitals or long-term care facilities in different countries, and collected data from a variety of healthcare workers. Fourteen studies assessed the success of different combinations of strategies recommended by the World Health Organization (WHO) to improve hand hygiene compliance. Strategies consisted of the following: increasing the availability of ABHR, different types of education for staff, reminders (written and verbal), different types of performance feedback, administrative support, and staff involvement. Six studies assessed different types of performance feedback, two studies evaluated education, three studies evaluated cues such as signs or scent, and one study assessed placement of ABHR. Observed hand hygiene compliance was measured in all but three studies which reported product usage. Eight studies also reported either infection or colonisation rates. All studies had two or more sources of high or unclear risks of bias, most often associated with blinding or independence of the intervention.Multimodal interventions that include some but not all strategies recommended in the WHO guidelines may slightly improve hand hygiene compliance (five studies; 56 centres) and may slightly reduce infection rates (three studies; 34 centres), low certainty of evidence for both outcomes.Multimodal interventions that include all strategies recommended in the WHO guidelines may slightly reduce colonisation rates (one study; 167 centres; low certainty of evidence). It is unclear whether the intervention improves hand hygiene compliance (five studies; 184 centres) or reduces infection (two studies; 16 centres) because the certainty of this evidence is very low.Multimodal interventions that contain all strategies recommended in the WHO guidelines plus additional strategies may slightly improve hand hygiene compliance (six studies; 15 centres; low certainty of evidence). It is unclear whether this intervention reduces infection rates (one study; one centre; very low certainty of evidence).Performance feedback may improve hand hygiene compliance (six studies; 21 centres; low certainty of evidence). This intervention probably slightly reduces infection (one study; one centre) and colonisation rates (one study; one centre) based on moderate certainty of evidence.Education may improve hand hygiene compliance (two studies; two centres), low certainty of evidence.Cues such as signs or scent may slightly improve hand hygiene compliance (three studies; three centres), low certainty of evidence.Placement of ABHR close to point of use probably slightly improves hand hygiene compliance (one study; one centre), moderate certainty of evidence.

AUTHORS' CONCLUSIONS

With the identified variability in certainty of evidence, interventions, and methods, there remains an urgent need to undertake methodologically robust research to explore the effectiveness of multimodal versus simpler interventions to increase hand hygiene compliance, and to identify which components of multimodal interventions or combinations of strategies are most effective in a particular context.

Staphylococcus aureus surface contamination of mobile phones and presence of genetically identical strains on the hands of nursing personnel

We investigated the genetic relatedness of Staphylococcus aureus isolates recovered from mobile phones and palms and fingers of users. Genetically identical isolates were detected from mobile phones and their user and multiple users, which is consistent with mobile phones serving as reservoirs of infection in the health care environment. These findings reinforce the need for hand hygiene prior to patient contact as the most effective intervention for preventing health care-associated infection.

Hand Hygiene: An Update

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

A Case Study on Improving Intensive Care Unit (ICU) Services Reliability: By Using Process Failure Mode and Effects Analysis (PFMEA)

Introduction:

In any complex human system, human error is inevitable and shows that can’t be eliminated by blaming wrong doers. So with the aim of improving Intensive Care Units (ICU) reliability in hospitals, this research tries to identify and analyze ICU’s process failure modes at the point of systematic approach to errors.

Methods:

In this descriptive research, data was gathered qualitatively by observations, document reviews, and Focus Group Discussions (FGDs) with the process owners in two selected ICUs in Tehran in 2014. But, data analysis was quantitative, based on failures’ Risk Priority Number (RPN) at the base of Failure Modes and Effects Analysis (FMEA) method used. Besides, some causes of failures were analyzed by qualitative Eindhoven Classification Model (ECM).

Results:

Through FMEA methodology, 378 potential failure modes from 180 ICU activities in hospital A and 184 potential failures from 99 ICU activities in hospital B were identified and evaluated. Then with 90% reliability (RPN≥100), totally 18 failures in hospital A and 42 ones in hospital B were identified as non-acceptable risks and then their causes were analyzed by ECM.

Conclusions:

Applying of modified PFMEA for improving two selected ICUs’ processes reliability in two different kinds of hospitals shows that this method empowers staff to identify, evaluate, prioritize and analyze all potential failure modes and also make them eager to identify their causes, recommend corrective actions and even participate in improving process without feeling blamed by top management. Moreover, by combining FMEA and ECM, team members can easily identify failure causes at the point of health care perspectives.

Fighting MRSA Infections in Hospital Care: How Organizational Factors Matter

OBJECTIVE

To identify factors associated with methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections at the level of the hospital organization.

DATA SOURCES

Data from all 173 acute trusts in the English National Health Service (NHS).

STUDY DESIGN

A longitudinal study based on trust-level panel data for the 5-year period from April 2004 to March 2009. Fixed effects negative binominal and system generalized method of moment models were used to examine the effect of (i) patient mix characteristics, (ii) resource endowments, and (iii) infection control practices on yearly MRSA counts.

DATA COLLECTION

Archival and staff survey data from multiple sources, including Public Health England, the English Department of Health, and the Healthcare Commission, were merged to form a balanced panel dataset.

PRINCIPAL FINDINGS

MRSA infections decrease with increases in general cleaning (-3.52 MRSA incidents per 1 standard deviation increase; 95 percent confidence interval: -6.61 to -0.44), infection control training (-3.29; -5.22 to -1.36), hand hygiene (-2.72; -4.76 to -0.68), and error reporting climate (-2.06; -4.09 to -0.04).

CONCLUSIONS

Intensified general cleaning, improved hand hygiene, additional infection control training, and a climate conducive to error reporting emerged as the factors most closely associated with trust-level reductions in MRSA infections over time.

Promoting Hand Hygiene With a Lighting Prompt

OBJECTIVES

The objective of this pilot study was to assess an automatic sink light design intervention as a prompt for clinician hand hygiene (as defined by World Health Organization [WHO]).

BACKGROUND

Healthcare-associated infections (HAIs) are still leading causes of morbidity and mortality and contribute to burdens on our healthcare system. Hand hygiene has been related to reducing the rate of HAIs and positively impacting both patient and hospital outcomes.

METHODS

This pilot study was a prospective, longitudinal observational study of a convenience sample of healthcare clinicians. In one inpatient room, clinicians were exposed to a hand hygiene reminder that consisted of a light turning on over the sink as they entered. A control room (the adjacent inpatient room) did not have the intervention.

RESULTS

A total of 88 clinician encounters were monitored during the study. On the first observation day at the initial activation of the signal light system, the percentage of clinicians performing hand hygiene upon entering a room was only 7% in the control room and 23% in the intervention room. During the second observation (Day 14), those percentages were 16% in the control room and 30% in the intervention room. During the third observation (Day 21), those percentages were 23% in the control room and 23% in the intervention room.

CONCLUSIONS

The healthcare system frequently relies on expensive technology to improve healthcare delivery, but implementation of low-cost, low-technology methods such as this light may be effective in prompting hand hygiene.

Compliance with hand hygiene: reference data from the national hand hygiene campaign in Germany

Hand hygiene is a key measure to prevent healthcare-associated infection. To promote hand hygiene nationally the German campaign 'Aktion Saubere Hände' was launched in January 2008, based on the World Health Organization's 'Clean Care is Safer Care' initiative. We report the first results from a full year of data collection on hand hygiene compliance recorded with the help of a renewed observation tool. Data were based on submissions from 109 participating hospitals collected from 576 wards between January 1st and December 31st, 2014. The overall median compliance was 73%, ranging from 55% (10th percentile) to 89% (90th percentile). The results demonstrated only small differences between adult and non-adult intensive care units (ICUs) with neonatal ICUs and paediatric non-ICUs maintaining higher compliance than adult care units. Performance among nurses was better than physicians, and overall rates of hand hygiene performance were significantly higher after patient contact than before.

Cost-effectiveness of a hand hygiene program on health care-associated infections in intensive care patients at a tertiary care hospital in Vietnam

BACKGROUND

The cost-effectiveness of a hand hygiene (HH) program in low- and middle-income countries (LMICs) is largely unknown. We assessed the cost-effectiveness of a HH program in a large tertiary Vietnamese hospital.

METHODS

This was a before and after study of a hand hygiene program where HH compliance, incidence of hospital-acquired infections (HAIs), and costs were analyzed.The HH program was implemented in 2 intensive care and 15 critical care units. The program included upgrading HH facilities, providing alcohol-based handrub at point of care, HH campaigns, and continuous HH education.

RESULTS

The HH compliance rate increased from 25.7% to 57.5% (P < .001). The incidence of patients with HAI decreased from 31.7% to 20.3% (P < .001) after the intervention. The mean cost for patients with HAI was $1,908, which was 2.5 times higher than the costs for patients without an HAI. The mean attributable cost of an HAI was $1,131. The total cost of the HH program was $12,570, which equates to a per-patient cost of $6.5. The cost-effectiveness was estimated at -$1,074 or $1,074 saved per HAI prevented. The intervention remained cost savings under various scenarios with lower HAI rates.

CONCLUSION

The HH program is an effective strategy in reducing the incidence of HAIs in intensive care units and is cost-effective in Vietnam. HH programs need to be encouraged across Vietnam and other LMICs.

Predicting severe enterovirus 71 infection: Age, comorbidity, and parental behavior matter

OBJECTIVE

Enterovirus 71 (EV71) is one of the major pathogens that cause severe enteroviral infections. Our aim was to study the behavioral and household risk factors for its serious complications.

METHODS

Between May 2011 and November 2012, we enrolled children who had symptoms of EV71 infection from six hospitals in Taiwan. The caregivers of each patient were interviewed to determine their hand hygiene habits in relation to EV71 infection. The severity of EV71 infection was classified as follows: Stage 1, hand-foot-mouth disease or herpangina; Stage 2, meningitis or myoclonic jerk; Stage 3A, encephalitis; Stage 3B, cardiopulmonary failure. Stages 2 to 3B were defined as severe EV71 infection. Children with Stages 3A and 3B infection were designated as the critical group.

RESULTS

A total of 399 patients had laboratory-confirmed EV71 infection. Three risks factors were associated with the different degrees of severity in EV71 infection. Children <2 years old had much greater risks for severe EV71 infection [odds ratio (OR) 1.8; 95% confidence interval (CI), 1.2-2.8], delayed medical evaluation for critical infection (OR 9.4; 95% CI, 3.6-24.1), and developmental retardation for cardiopulmonary failure (OR 8.3; 95% CI, 2.0-33.7). Among all the habits and household factors, caregivers in the critical group had a significantly lower rate in terms of cleaning the faucet after washing their hands (OR 2.63; 95% CI, 1.14-6.08).

CONCLUSIONS

Children <2 years old, developmental retardation, and delayed medical intervention were associated with severe EV71 infection. Cleaning water faucets after hand washing was a protective habit that reduced the risk of complications.

Changes in healthcare-associated Staphylococcus aureus bloodstream infections after the introduction of a national hand hygiene initiative

BACKGROUND

Interventions that prevent healthcare-associated infection should lead to fewer deaths and shorter hospital stays. Cleaning hands (with soap or alcohol) is an effective way to prevent the transmission of organisms, but rates of compliance with hand hygiene are sometimes disappointingly low. The National Hand Hygiene Initiative in Australia aimed to improve hand hygiene compliance among healthcare workers, with the goal of reducing rates of healthcare-associated infection.

METHODS

We examined whether the introduction of the National Hand Hygiene Initiative was associated with a change in infection rates. Monthly infection rates for healthcare-associated Staphylococcus aureus bloodstream infections were examined in 38 Australian hospitals across 6 states. We used Poisson regression and examined 12 possible patterns of change, with the best fitting pattern chosen using the Akaike information criterion. Monthly bed-days were included to control for increased hospital use over time.

RESULTS

The National Hand Hygiene Initiative was associated with a reduction in infection rates in 4 of the 6 states studied. Two states showed an immediate reduction in rates of 17% and 28%, 2 states showed a linear decrease in rates of 8% and 11% per year, and 2 showed no change in infection rates.

CONCLUSIONS

The intervention was associated with reduced infection rates in most states. The failure in 2 states may have been because those states already had effective initiatives before the national initiative's introduction or because infection rates were already low and could not be further reduced.
