Interventions to improve patient hand hygiene: a systematic review

Should automated electronic hand-hygiene monitoring systems be implemented in routine patient care? Systematic review and appraisal with Medical Research Council Framework for Complex Interventions

Manual hand-hygiene audit is time-consuming, labour-intensive and inaccurate. Automated hand-hygiene monitoring systems (AHHMSs) offer advantages (generation of standardized data, avoidance of the Hawthorne effect). World Health Organization Guidelines for Hand Hygiene published in 2009 suggest that AHHMSs are a possible alternative. The objective of this review was to assess the current state of the literature for AHHMSs and offer recommendations for use in real-world settings. This was a systematic literature review, and publications included were from the time that PubMed commenced until 19th November 2023. Forty-three publications met the criteria. Using the Medical Research Council's Framework for Developing and Evaluating Complex Interventions, two were categorized as intervention development studies. Thirty-nine were evaluations. Two described implementation in real-world settings. Most were small scale and short duration. AHHMSs in conjunction with additional intervention (visual or auditory cue, performance feedback) could increase hand hygiene compliance in the short term. Impact on infection rates was difficult to determine. In the few publications where costs and resources were considered, time devoted to improving hand hygiene compliance increased when an AHHMS was in use. Health workers' opinions about AHHMSs were mixed. In conclusion, at present too little is known about the longer-term advantages of AHHMSs to recommend uptake in routine patient care. Until more longer-term accounts of implementation (over 12 months) become available, efforts should be made to improve direct observation of hand hygiene compliance to improve its accuracy and credibility. The Medical Research Council Framework could be used to categorize other complex interventions involving use of technology to prevent infection to help establish readiness for implementation.

Novel hand hygiene promotion method in a pediatric and maternity hospital: A quality improvement pilot project using auditory feedback

A pilot quality improvement project was conducted to examine the effect of playing an applause sound effect at a busy hospital concourse for three consecutive days whenever hand hygiene behavior was observed. The immediate effect was documented. The project demonstrated observable interest among people passing by, and hand hygiene events triggered by the sound effect represented 10.1% of all hand hygiene events documented. This supports the possible utility of this intervention in generating public awareness and increasing hand hygiene behavior and demonstrates the feasibility of a longer trial utilizing audio devices.

COVID-19 Pandemisi tıp öğrencilerinin ve uzmanlık öğrencilerinin el hijyenine uyumunu değiştiriyor mu? Bir üniversite hastanesinden karşılaştırmalı çalışma

Aim: We aimed to find out if there is statistically significant difference in self-reported hand hygiene compliance among Year-5 medical students, Year-6 medical students, and residents in Gazi University Faculty of Medicine between right before and after the first confirmed case of COVID-19 in Turkiye. Materials and Methods: Two cross-sectional surveys were carried out to reveal self-reported hand hygiene compliance among participants right before and after the first confirmed case of COVID-19 in Turkiye. Participants were Year-5 and Year-6 medical students and residents in Gazi University Faculty of Medicine. Convenience sampling was used. There were 833 participants in total. The survey form consists of 10 items that were constituted by examining World Health Organization guidelines on hand hygiene. The compliance scores before and after the first confirmed case were compared by performing T-Test. Results: Out of 10 items, there was significant difference in Year-5 medical students’, Year-6 medical students’ and residents’ self-reported hand hygiene compliance scores between before and after the first confirmed case of COVID-19 in 6 items, 10 items, and 8 items, respectively (p

Hand hygiene practices for prevention of health care-associated infections associated with admitted infectious patients in the emergency department: a systematic review

Background

In most high-income countries, emergency departments (ED) represent the principal point of access forcer by critically ill or injured patients. Unlike inpatient units, ED healthcare workers (ED HCWs) have demonstrated relative lack of adherence to hand hygiene (HH) guidelines, commonly citing frequency of intervention and high rates of admission, which reflect severity of cases encountered.

Aim

Assessment of studies on hand hygiene compliance (HHC) by ED HCWs conducted between 2010 and 2020, seeking to estimate HHC rates and intervention strategies utilised to improve HHC in EDs.

Methods

Searches conducted in Web of Science, EBSCO HOST (CINHAL & Medline), PubMed, Embase, and Cochrane for full studies published between 2010 and 2020 on the topic of HHC in the ED.

Results

One hundred twenty-nine eligible articles were identified of which 79 were excluded. Fifty-one underwent full-text screening before 20 studies were deemed relevant. Of the eligible studies, fifteen (75%) had, as the primary outcome, HHC according to the WHO-recommended 5-moments. Twelve studies (60%) implemented multimodal or single intervention strategies. Eight studies were ambiguous regarding the nature of the approach adopted. In the nine observational studies where HHC was documented, an overall post-intervention median HHC rate of 45% (range 8–89.7%).

Conclusion

Multimodal approaches appear to have enhanced HHC moderately among ED HCWs. Elevated complexity associated with critically ill patients, and ED overcrowding, are contributing factors to relatively low compliance rates observed. Strategies to improve HHC rates may need to acknowledge, and cater for, the context of an unpredictable environment.

Increasing patient participation in hand hygiene practices in adult surgical wards in a tertiary institution: a best practice implementation project

INTRODUCTION

The WHO states that hospital-acquired infections may be transmitted through contaminated hands. Practicing hand hygiene using alcohol-based handrub or soap and water reduces harmful organisms. The Joanna Briggs Institute (JBI) best practice recommends empowering patients with hand hygiene knowledge and engaging their involvement to strengthen hand hygiene practices.

AIMS

The aim of this project was to improve hand hygiene among surgical inpatients.

METHODS

This evidence-based quality improvement project was conducted in three phases: the baseline audit, implementing best practice, and the postimplementation audit. Participants were patients hospitalized in three surgical wards of a 1200-bed acute care tertiary hospital. This project utilized the online JBI Practical Application of Clinical Evidence System and The Getting Research into Practice program to identify barriers and strategies. Nurses provided patients with an education pamphlet and regularly reminded them to improve their hand hygiene practices.

RESULTS

Ninety-four patients were audited between April and June 2018. Patients' hand hygiene practices improved from 19.1% at baseline audit to 61.7% (P < 0.01) at first follow-up audit. Patients' hand hygiene improved from 48.9 to 72.3% (P = 0.03) before meals, and from 92.6 to 98.9% (P = 0.65) after toileting. The proportion of patients who received a hand hygiene information leaflet in an appropriate language increased from 64.9 to 89.4% (P < 0.01).

CONCLUSION

Patients' involvement in the hand hygiene program has significantly improved their hand hygiene practices. Patient education and patient information leaflet continue to be an effective strategy to improve knowledge and practices.

Patient, family, and visitor hand hygiene knowledge, attitudes, and practices at pediatric and maternity hospitals: A descriptive study

BACKGROUND

Patient, family, and visitor hand hygiene can prevent health care-associated infections, but little is known about their hand hygiene knowledge, attitudes, and practices. We aimed to assess patient, family, and visitor hand hygiene knowledge, attitudes, and practices at a pediatric and maternity hospital in Vancouver, British Columbia, Canada.

METHODS

Surveys based on the Theoretical Domains Framework were distributed to patients, families, and visitors to provide cross-sectional qualitative and quantitative data. This was supplemented with covert observations by trained medical students to determine patient, family, and visitor hand hygiene rates.

RESULTS

Of 348 survey respondents, there was a clear preference for hand washing with soap and water over use of alcohol-based hand rub. Beliefs about consequences were the main driver for hand hygiene. Self-reported hand hygiene rates were higher than observed rates. The overall hand hygiene rate was observed to be 10.3% (72/701), with soap and water used for 75% of hand hygiene events.

CONCLUSION

There are misconceptions regarding hand hygiene practices and low hand hygiene rates among patients, families, and visitors. Development of interventions to improve hand hygiene should focus on correcting misconceptions and emphasizing consequences of failing to perform hand hygiene in the health care setting.

An interventional implementation project: hand hygiene improvement

Background

Good hand hygiene is the most effective basic measure for preventing hospital-acquired infections. This research project, which originated from a project report on improving hand hygiene at a general hospital in Hangzhou, Zhejiang, China, aimed to investigate the effectiveness of hand hygiene improvement among the hospital staff.

Methods

Since 2017, a hand hygiene improvement project involving the staff of a 2,500-bed general teaching hospital in Zhejiang, China, has been carried out. This study summarized the implementation and effectiveness of the project, which is based on the five factors of systematic evaluation. The research summary was divided into three phases: phase I (December 2017 to August 2018), phase 2 (September 2018 to April 2019), and phase 3 (May 2019 to December 2019). The data of hand hygiene compliance rates of different groups of professionals in the different research periods were statistically analyzed.

Results

The results showed that continuous intervention led to a gradual increasing trend (Ptrend<0.001) in the hand hygiene implementation rate with as the intervention time and phases progressed. The hand hygiene compliance rates differed significantly during different phases (76.61%, 79.95%, and 83.34% in phases 1, 2, and 3, respectively, P<0.001). At the same time, the compliance rates of hand hygiene at each phase differed significantly between different professions (P<0.001, the compliance rate of hand hygiene among nurses was the highest and lowest among workers). The compliance rate of hand hygiene for different professions during the three phases were: nurses, 84.73%; doctors, 78.35%; interns, 77.62%; and other hospital workers, 72.79%.

Conclusions

The hand hygiene compliance rate was effectively improved among the hospital staff after the implementation of the hand hygiene improvement project. In this hospital, the project yielded remarkable results. Hand hygiene must be continuously practiced and improved to develop good habits. Effective and detailed planning as well as key factors, such as hand hygiene facilities, information monitoring, the active participation and response of employees, training and education, and supervision and feedback, could help to guarantee the effectiveness of the project.

Active Integration of Patients into Infection Control, as perceived by Health Care Professionals: Results of the AHOI Pilot Study

Objective

Medical professionals have a key role in active patient involvement in infection control and prevention (ICP). ICP of hospital-associated infections is critical for patient safety and requires targeted integration of patients and their relatives. The possibilities of proper involvement are identified, tested and realized in the innovative AHOI project. Its acronym stands for Activation, Help, Open communication and Infection prevention. The project is based on the three dimensions acceptance, empowerment and adherence. The results presented here are from a health-care professional (HCP) focused part of a pilot study to implement AHOI intervention. This section aimed at the HCPs’ evaluation of the intervention material, their perception and acceptance of the adherence and empowerment of patients, as well as the perception of their and colleagues’ own behavior.

Methods

The cross-sectional survey was conducted with a questionnaire at two surgical wards of a third-level hospital for 14 weeks. All HCPs with contact to patients were entitled to voluntarily participate in the study. AHOI instruments such as visual reminder, videos for patients and the AHOI-box were implemented on the wards. Additionally, the ward personnel received a psychological and practical train-the-trainer curriculum.

Results

Sixty-nine questionnaires were handed out and 29 returns were analyzed. The results show a strong identification and acceptance of HCPs with their role in the AHOI project. No additional workload was perceived by implementing AHOI. Teaching of medical professionals and information materials are seen as good supports. HCPs are empowering hygienic behavior in patients and colleagues. HCPs observed increasing adherence of patients.

Conclusion

HCPs positively perceived acceptance, support and identification with the ideas of the AHOI project. Therefore, since HCPs are key for patients and their relatives, AHOI intervention seems to be a feasible instrument and aid in implementing national and international recommendations for hygienic behavior.

Home care nurses' identification of patients at risk of infection and their risk mitigation strategies: A qualitative interview study

BACKGROUND

There is an increase in the number of individuals who receive care at home. A significant proportion of these patients acquire infections during their care episode. Whilst there has been significant focus on strategies for infection prevention and control in acute care environments, there is a lack of research into infection prevention in a home care setting.

OBJECTIVES

To understand (1) if and how home care nurses identify patients at high risk of infection and (2) the strategies they use to mitigate that risk.

DESIGN

A qualitative descriptive study, using semi-structured interviews.

SETTING

A large not for profit home care agency located in the New York region of the United States.

PARTICIPANTS

Fifty nurses with a range of experience in home care nursing.

METHODS

Purposive and snowball sampling was used to recruit nurses from across the home care agency with varied years of work experience. Interviews were audio recorded and transcribed. The interviews explored how home care nurses evaluate their patients' risk of developing an infection and if/how they modify the plan of care based on that risk. Data were analysed using thematic analysis.

RESULTS

Three themes were derived from the data; assessing a patient's risk of infection, the risk assessment process, and strategies for mitigating infection risk. Factors identified by nurses as putting a patient at higher risk of infection included being older, having diabetes, inadequate nutrition; along with inadequate clinical information available at start of care. The patient's knowledge and understanding of infection prevention, and the availability and knowledge of caregivers were also important, as was the cleanliness of the home environment. Given the context of home care, where nurses have little control over the environment and care processes in-between visits, the main strategy for infection prevention was patient and caregiver education. Nurses also discussed the importance of their own infection prevention behaviours, and the ability to adjust a patient's plan of care according to their infection risk.

CONCLUSIONS

The study highlights the complexity of the risk assessment process in relation to infection. Existing guidelines for infection prevention and control do not adequately cover the home care environment and more research needs to determine which interventions (such as patient/caregiver education) would be most effective to prevent infections in the home care setting.

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).

Impact of patient and visitor hand hygiene interventions at a pediatric hospital: A stepped wedge cluster randomized controlled trial

BACKGROUND

Patient and visitor hand hygiene has the potential to prevent health care-associated infections, but there are few data on the efficacy of interventions to improve patient/visitor hand hygiene.

OBJECTIVE

To determine whether conventional and front-line ownership (FLO) patient/visitor hand hygiene interventions improve patient/visitor and health care worker (HCW) hand hygiene rates.

METHODS

A stepped wedge cluster randomized controlled trial was conducted on inpatient units and the emergency department. A conventional intervention included pediatric-focused posters, which also served as reminders for HCWs. This was compared to a FLO intervention aimed at finding "positive deviants," staff who were already taking steps to improve patient/visitor hand hygiene. Patient/visitor and HCW hand hygiene rates were measured covertly by trained medical students.

RESULTS

Patient/visitor hand hygiene rates increased from 9.2% at baseline to 13.9% in the post-intervention period. Hand hygiene rates on units randomized to the standard intervention changed from 7.3% to 10.9% (P = .46), but FLO intervention units significantly changed from 14.3% to 25% (P = .03). The baseline HCW hand hygiene rate was 68.2%, which increased to a greater extent in the FLO group (79.1%) than in the standard intervention (73.1%), but the change was not statistically significant for either intervention compared to control (P = .18 and P = .64, respectively).

CONCLUSIONS

Hand hygiene interventions in hospitals can improve patient/visitor and HCW hand hygiene rates, and a FLO intervention appears to be more effective than a conventional intervention.

Improving children's and their visitors' hand hygiene compliance

Background

Numerous interventions have tried to improve healthcare workers' hand hygiene compliance. However, little attention has been paid to children's and their visitors' compliance.

Aim

To test whether interactive educational interventions increase children's and visitors' compliance with hand hygiene.

Methods

This was a cluster randomised study of hand hygiene compliance before and after the introduction of educational interventions. Observations were compared for different moments of hygiene and times of the day. Qualitative data in the form of questionnaire-based structured interviews were obtained.

Findings

Hand hygiene compliance increased by 24.4% (P < 0.001) following the educational interventions, with children's compliance reaching 40.8% and visitors' being 50.8%. Compliance varied depending on which of the five moments of hygiene was observed (P < 0.001), with the highest compliance being 'after body fluid exposure' (72.7%). Responses from questionnaires showed educational interventions raised awareness of the importance of hand hygiene (69%, 57%) compared to those who had not experienced the educational intervention (50%).

Conclusion

Educational interventions may result in a significant increase in children's and visitors' hand hygiene (P < 0.001).

Multidrug-resistant Organisms in Hospitals: What Is on Patient Hands and in Their Rooms?

BACKGROUND

The impact of healthcare personnel hand contamination in multidrug-resistant organism (MDRO) transmission is important and well studied; however, the role of patient hand contamination needs to be characterized further.

METHODS

Patients from 2 hospitals in southeast Michigan were recruited within 24 hours of arrival to their room and followed prospectively using microbial surveillance of nares, dominant hand, and 6 high-touch environmental surfaces. Sampling was performed on admission, days 3 and 7, and weekly until discharge. Paired samples of methicillin-resistant Staphylococcus aureus (MRSA) isolated from the patients' hand and room surfaces were evaluated for relatedness using pulsed-field gel electrophoresis and staphylococcal cassette chromosome mec, and Panton-Valentine leukocidin typing.

RESULTS

A total of 399 patients (mean age, 60.8 years; 49% male) were enrolled and followed for 710 visits. Fourteen percent (n = 56/399) of patients were colonized with an MDRO at baseline; 10% (40/399) had an MDRO on their hands. Twenty-nine percent of rooms harbored an MDRO. Six percent (14/225 patients with at least 2 visits) newly acquired an MDRO on their hands during their stay. New MDRO acquisition in patients occurred at a rate of 24.6/1000 patient-days, and in rooms at a rate of 58.6/1000 patient-days. Typing demonstrated a high correlation between MRSA on patient hands and room surfaces.

CONCLUSIONS

Our data suggest that patient hand contamination with MDROs is common and correlates with contamination on high-touch room surfaces. Patient hand hygiene protocols should be considered to reduce transmission of pathogens and healthcare-associated infections.

How often are health care personnel hands colonized with multidrug- resistant organisms? A systematic review and meta-analysis

BACKGROUND

Hands of health care personnel (HCP) can transmit multidrug-resistant organisms (MDROs), resulting in infections. Our aim was to determine MDRO prevalence on HCP hands in adult acute care and nursing facility settings.

METHODS

A systematic search of PubMed/MEDLINE, Web of Science, CINAHL, Embase, and Cochrane CENTRAL was performed. Studies were included if they reported microbiologic culture results following HCP hands sampling; included prevalent MDROs, such as methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus, Clostridium difficile, Acinetobacter baumannii, or Pseudomonas aeruginosa, and were conducted in acute care or nursing facility settings.

RESULTS

Fifty-nine articles comprising 6,840 hand cultures were included. Pooled prevalence for MRSA, P aeruginosa, A baumannii, and vancomycin-resistant Enterococcus were 4.26%, 4.59%, 6.18%, and 9.03%, respectively. Substantial heterogeneity in rates of pathogen isolation were observed across studies (I² = 81%-95%). Only 4 of 59 studies sampled for C difficile, with 2 of 4 finding no growth. Subgroup analysis of MRSA revealed the highest HCP hand contamination rates in North America (8.28%). Sample collection methods used were comparable for MRSA isolation (4%-7%) except for agar direct contact (1.55%).

CONCLUSIONS

Prevalence of common MDROs on HCP hands vary by pathogen, care setting, culture acquisition method, study design, and geography. When obtained at an institutional level, these prevalence data can be utilized to enhance knowledge, practice, and research to prevent health care-associated infections.

A multimodal intervention to improve hand hygiene compliance in a tertiary care center

BACKGROUND

Healthcare-associated infections (HAIs) are a major threat to patient safety worldwide. HAIs are mainly transmitted via the hands of healthcare workers (HCWs), and HCW compliance with hand hygiene (HH) practices is reportedly low. Therefore, multimodal interventions are needed to develop effective HH improvement strategies. In this study, we assessed the effect of multimodal interventions on improvement of HH compliance.

METHODS

This study was conducted in 2 intensive care units from August 2016 to October 2016. It encompassed 3 phases: pre-intervention (20 days), intervention (1 month), and post-intervention (20 days). A total of 53 HCWs, including physicians, nurses, and housekeeping staff, were included in the HH audit. The audit was analyzed by direct observation and by a completed knowledge, attitude, and practice (KAP) questionnaire.

RESULTS

A total of 6350 HH opportunities were recorded; the results were 34.7%, 35%, and 69.7% for hand hygiene complete adherence rate (HHCAR), hand hygiene partial adherence rate (HHPAR), and hand hygiene adherence rate (HHAR), respectively. The HHCAR in the pre-intervention and post-intervention phases were 3% and 70.1%, respectively. HHCAR was highest among nurses (3.6% in the pre-intervention phase and 80.7% in the post-intervention phase). Other findings were that senior physicians had better HH compliance than junior physicians; in the pre-intervention phase, the HHCAR was better in the evening (4.8%); in the post-intervention phase, the HHCAR was better in the morning (72.1%); women had a higher HHCAR than men; and in the pre-intervention phase, good compliance was seen with Moments 2 and 3 of the World Health Organization's (WHO) Five Moments for Hand Hygiene, whereas in the post-intervention phase, good compliance was seen with Moments 3, 4, and 5. Questionnaire-based data were also analyzed to assess KAP of HH. We found that only 55%-82% of HCWs were aware of the WHO's Five Moments for Hand Hygiene. In the post-intervention phase, we observed a significant improvement in KAP of the study group.

CONCLUSION

Significant improvement in HH compliance can be achieved through a systematic, multidimensional intervention involving all types of HCWs.

Patient Involvement in Healthcare-Associated Infection Research: A Lexical Review

OBJECTIVEThis review examines patient involvement in healthcare-associated infection (HAI) research. Healthcare-associated infections represent an intractable issue with considerable implications for patients and staff. Participatory methodologies that involve patients in healthcare research are associated with myriad benefits.DESIGNLexical review.METHODSPubMed was searched to identify all publications on patient involvement in HAI research since 2000; publications were also identified from the cited references. A lexical analysis was conducted of the methods sections of 148 publications.RESULTSThe findings reveal that HAI research that actively involves patients and members of the public is limited.CONCLUSIONSPatient involvement is largely limited to recruitment to HAI studies rather than extended to patient involvement in research design, implementation, analysis, and/or dissemination. As such, there is considerable opportunity to further this important research area via alternative methodologies that award primacy to patient expertise and agency.Infect Control Hosp Epidemiol 2018;39:710-717.

Pilot study of digital tools to support multimodal hand hygiene in a clinical setting

BACKGROUND

Digital tools for hand hygiene do not share data, limiting their potential to support multimodal programs. The Christie NHS Foundation Trust, United Kingdom, worked with GOJO (in the United States), MEG (in Ireland), and SureWash (in Ireland) to integrate their systems and pilot their combined use in a clinical setting.

METHODS

A 28-bed medical oncology unit piloted the system for 5 weeks. Live data from the tools were combined to create a novel combined risk status metric that was displayed publicly and via a management Web site.

RESULTS

The combined risk status reduced over the pilot period. However, larger and longer duration studies are required to reach statistical significance. Staff and especially patient reaction was positive in that 70% of the hand hygiene training events were by patients. The digital tools did not negatively impact clinical workflow and received positive engagement from staff and patients. The combined risk status did not change significantly over the short pilot period because there was also no specific hand hygiene improvement campaign underway at the time of the pilot study.

CONCLUSIONS

The results indicate that integrated digital tools can provide both rich data and novel tools that both measure impact and provide feedback to support the implementation of multimodal hand hygiene campaigns, reducing the need for significant additional personnel resources.

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.

Patient Hand Colonization With MDROs Is Associated with Environmental Contamination in Post-Acute Care

We assessed multidrug-resistant organism (MDRO) patient hand colonization in relation to the environment in post-acute care to determine risk factors for MDRO hand colonization. Patient hand colonization was significantly associated with environmental contamination. Risk factors for hand colonization included disability, urinary catheter, recent antibiotic use, and prolonged hospital stay. Infect Control Hosp Epidemiol 2017;38:1110-1113.

Smartphone text message service to foster hand hygiene compliance in health care workers

BACKGROUND

Health care-associated infections are a major worldwide public health issue. Hand hygiene is a major component in the prevention of pathogen transmission in hospitals, and hand hygiene adherence by health care workers is low in many studies. We report an intervention using text messages as reminders and feedback to improve hand hygiene adherence.

MATERIALS AND METHODS

The study is a historical comparison proof-of-concept study. Eighteen health care workers were monitored during 12 months by a radiofrequency identification system. Afterward we sent 2 types of text messages, congratulation or encouragement, and we studied the evolution of hand hygiene adherence.

RESULTS

We recorded 15,723 hand hygiene opportunities, 8,973 before intervention and 6,750 during and after the intervention. Using a multilevel logistic regression analysis, we found a significant increase in hand hygiene adherence during the intervention (odds ratio, 1.68) compared with the historical period.

DISCUSSION

Despite limitations due to the type of study, a text message encouraging personnel to be more vigilant is effective in increasing hand hygiene adherence in health care workers.

CONCLUSIONS

Text message feedback should be incorporated into multimodal approaches for improving hand hygiene compliance.
