Investigating the use of an electronic hand hygiene monitoring and prompt device: influence and acceptability

Evaluating the accuracy of an automatic counting system to detect dispensing of hand hygiene product

BACKGROUND

Hand hygiene (HH) is an essential element of infection prevention and control programs. Direct observation of adherence to the 5 moments for HH is considered the gold standard in compliance monitoring. However, as direct observation introduces potential bias, other strategies have been proposed to supplement HH compliance data in healthcare facilities. This study evaluated the accuracy of an automatic counting system (MEZRIT™) to detect when a HH product (soap or alcohol-based hand rub) was dispensed, and thus measure product usage as opposed to compliance with the 5 moments for HH.

METHODS

A quasi-experimental study was conducted in a nursing simulation lab where seven participants undertook basic nursing tasks which included performing HH. Sensors were attached to soap and alcohol-based hand rub dispensers to record the time at which a product was dispensed. HH events were video recorded (time-stamped) and validated against timestamps from the automatic counting system.

RESULTS

260 HH events were detected by the automatic counting system and confirmed by video recordings. 5182 non-HH events were calculated from analysis of the video recordings. The automatic counting system had 90 % sensitivity (95%CI 85.8-93.1 %), and 100 % specificity (95%CI 99.9-100 %). This model generated a positive predictive value of 100 % (95%Cl 98.4-100 %), and a negative predictive value of 99.5 % (95%CI 99.3-99.7 %).

CONCLUSION

The MEZRIT™ system accurately identified 90 % of HH events and excluded 100 % of non-HH events. The real-time monitoring of HH product usage may be beneficial in responding quickly to changes in product usage.

Impact of an electronic hand hygiene monitoring system on hand hygiene compliance

BACKGROUND

Health care worker hand hygiene (HH) is suboptimal. Electronic hand hygiene monitoring systems (EHHMS) record real-time HH events and may improve HH compliance. We evaluated if an EHHMS affected HH compliance.

METHODS

HH compliance of 6,711 inpatient health care workers was recorded in 9 hospitals for 30months using an EHHMS. Badge-wearing ratios (BWRs: number of staff wearing their monitoring badge/number of staff given a badge) and HH compliance rates were compared. Linear regression analysis and multivariate models compared BWRs across health care worker types and analyzed the interaction between BWRs and location.

RESULTS

There was a 1.9% increase in HH compliance for every 10-unit increase in BWR (t=6.65, P value <.001). Hospital location, health care worker type, and shift type significantly influenced HH compliance (F=115.7, df=[19,986], P value <.001, R2=0.69). BWRs and HH compliance were higher in hospitals that provided additional incentives to their health care workers.

CONCLUSIONS

Improved EHHMS badge-wearing correlated with increased HH compliance. Hospitals that provided incentives and placed a greater focus on HH had the most-improved HH compliance.

Healthcare staff perceptions of an electronic hand hygiene monitoring system within a large university system

Objective

The acceptability of an electronic HH monitoring system (EHHMS) was evaluated among hospital staff members.

Design

An electronic HH monitoring system was implemented in June 2020 at a large, academic medical center. An interdisciplinary team developed a cross-sectional survey to gather staff perceptions of the EHHMS.

Setting

The survey was conducted at a public, tertiary acute care hospital.

Participants

The survey included current employees and staff. 1,273 participants responded. The mean age was 44.9 years (SD = 13.5). Most of the samples were female (71%) and non-Hispanic white (83%).

Methods

A survey was conducted between June and July 2021. Responses were analyzed using Stata statistical software. Multiple logistic regression models were constructed to examine factors associated with negative perceptions of the EHHMS and its radiofrequency identification (RFID) badge. Supporting qualitative analyses were performed using Atlas.ti version 9.

Results

Three-quarters (75%) of respondents reported neutral to negative perceptions of the EHHMS and its associated badge. Respondents reported limited influence on HH practices. Age, campus location, length of employment, job role, and opinion on data sharing were associated with negative perceptions of the EHHMS and RFID badge. Position in a direct patient care role was associated with negative perceptions of the RFID badge.

Conclusions

Perceptions of the EHHMS aligned with previous research. Identified associations provide opportunities for targeted education, outreach, and intervention to increase acceptability and uptake. Lack of acceptance is explained by poorly perceived ease of use and usefulness, as well as challenges in implementation.

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.

Central aspects when implementing an electronic monitoring system for assessing hand hygiene in clinical settings: A grounded theory study

Background

New technologies, such as electronic monitoring systems, have been developed to promote increased adherence to hand hygiene among healthcare workers. However, challenges when implementing these technologies in clinical settings have been identified.

Aim

The aim of this study was to explore healthcare workers' experiences when implementing an electronic monitoring system to assess hand hygiene in a clinical setting.

Method

Interviews with healthcare workers (registered nurses, nurse assistants and leaders) involved in the implementation process of an electronic monitoring system (n = 17) were conducted and data were analyzed according to the grounded theory methodology formulated by Strauss and Corbin.

Results

Healthcare workers' experiences were expressed in terms of leading and facilitating, participating and contributing, and knowing and confirming. These three aspects were merged together to form the core category of collaborating for progress. Leaders were positive and committed to the implementation of the electronic monitoring system, endeavouring to enable facilitation and support for their co-workers (registered nurses and nurse assistants). At the same time, co-workers were positive about the support they received and contributed by raising questions and demands for the product to be used in clinical settings. Moreover, leaders and co-workers were aware of the objective of implementing the electronic monitoring system.

Conclusion

We identified dynamic collective work between leaders and co-workers during the implementation of the electronic monitoring system. Leadership, participation and knowledge were central aspects of enhancing a collaborative process. We strongly recommend involving both ward leaders and users of new technologies to promote successful implementation.

Empowering health care workers with personalized data-driven feedback to boost hand hygiene compliance

BACKGROUND

Achieving high hand hygiene compliance among health care workers is a challenge, requiring effective interventions. This study investigated the impact of individualized feedback on hand hygiene compliance using an electronic monitoring system.

METHODS

A quasi-experimental intervention design with pretest-post-test was conducted in an orthopedic surgical ward. Participants served as their own controls. A 3-month baseline was followed by a 3-month intervention period. Hand hygiene events were recorded through sensors on dispensers, name tags, and near patient beds. Health care workers received weekly email feedback reports comparing their compliance with colleagues.

RESULTS

Nineteen health care workers (17 nurses, 2 doctors) were included. Hand hygiene compliance significantly improved by approximately 15% (P < .0001) across all rooms during the intervention. The most substantial improvement occurred in patient rooms (17%, P < .0001). Compliance in clean and contaminated rooms increased by 10% (P = .0068) and 5% (P = .0232). The average weekly email open rate for feedback reports was 46%.

CONCLUSIONS

Individualized feedback via email led to significant improvements in hand hygiene compliance among health care workers. The self-directed approach proved effective, and continuous exposure to the intervention showed promising results.

Current issues in hand hygiene

BACKGROUND

Multiple aspects of hand hygiene have changed in recent years.

METHODS

A PubMed search was conducted to identify recent articles about hand hygiene.

RESULTS

The COVID-19 pandemic caused temporary changes in hand hygiene compliance rates and shortages of alcohol-based hand sanitizers (ABHSs), and in marketing of some products that were ineffective or unsafe. Fortunately, ABHSs are effective against SARS-CoV-2 and other emerging pathogens including Candida auris and mpox. Proper placement, maintenance, and design of ABHS dispensers have gained additional attention. Current evidence suggests that if an adequate volume of ABHS has been applied to hands, personnel must rub their hands together for at least 15 seconds before hands feel dry (dry time), which is the primary driver of antimicrobial efficacy. Accordingly, practical methods of monitoring hand hygiene technique are needed. Direct observation of hand hygiene compliance remains a challenge in many healthcare facilities, generating increased interest in automated hand hygiene monitoring systems (AHHMSs). However, several barriers have hindered widespread adoption of AHHMSs. AHHMSs must be implemented as part of a multimodal improvement program to successfully improve hand hygiene performance rates.

CONCLUSIONS

Remaining gaps in our understanding of hand hygiene warrant continued research into factors impacting hand hygiene practices.

Evaluating automatic hand hygiene monitoring systems: A scoping review

Objectives

To categorize the extant automatic hand hygiene monitoring systems (AHHMSs) and evaluate the capacity of each to provide information on compliance rates.

Study design

Scoping review.

Methods

Three international databases, PubMed, CINAHL, and EBSCO (between 1 January 2010 and 31 December 2020), were searched according to predetermined inclusion criteria for the scoping review. Two authors screened studies for eligibility independently. The review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR).

Results

Twenty-seven studies were included. Three types of AHHMSs were identified: Type I provides information about the aggregate hand hygiene events (HHEs) only, while Type II adds aggregate hand hygiene opportunities (HHOs), and Type III presents both HHEs and HHOs for individuals. Results suggested that improving the accuracy of recording HHEs and/or HHOs was critical for improving the accuracy of the compliance, which could increase the acceptability of the monitoring system. In addition, the studies found that the implementation of AHHMSs, especially with prompt reminders or additional interventions, could improve the compliance significantly.

Conclusions

The extant AHHMSs could be decomposed into components of 3Ps (product usage monitoring, position monitoring, and performance monitoring). By identifying devices and technology as well as the type of information provided for each component, our approach can aid healthcare facilities to choose a suitable AHHMS that meets their criteria.

Learning to interact with new technology: Health care workers' experiences of using a monitoring system for assessing hand hygiene - a grounded theory study

BACKGROUND

Recently, innovative technologies for hand hygiene (HH) monitoring have been developed to improve HH adherence in health care. This study explored health care workers' experiences of using an electronic monitoring system to assess HH adherence.

METHODS

An electronic monitoring system with digital feedback was installed on a surgical ward and interviews with health care workers using the system (n = 17) were conducted.  The data were analyzed according to grounded theory by Strauss and Corbin.

RESULTS

Health care workers' experiences were expressed in terms of having trust in the monitoring system, requesting system functionality and ease of use and becoming aware of one's own performance. This resulted in the core category of learning to interact with new technology, summarized as the main strategy when using an electronic monitoring system in clinical settings. The system with digital feedback improved the awareness of HH and individual feedback was preferable to group feedback.

CONCLUSIONS

Being involved in using and managing a technical innovation for assessing HH adherence in health care is a process of formulating a strategy for learning to interact with new technology. The importance of inviting health care workers to participate in the co-design of technical innovations is crucial, as it creates both trust in the innovation per se and trust in the process of learning how to use it.

Developing Internet of Things-related ISO 10001 Hand Hygiene Privacy Codes in healthcare

Purpose

Augmentation of an ISO 10001 code system for healthcare worker (HW) satisfaction with ISO/IEC 27701 and ISO/IEC 29184 privacy-related subsystems is shown. Four specific codes regarding the privacy of HWs using electronic devices for hand hygiene (HH) monitoring and the related activities are presented.

Design/methodology/approach

HWs’ concerns involving automated hand hygiene monitoring technologies were identified through a literature review and classified. Privacy codes (PCs) that deal with such concerns were developed. ISO/IEC 27701 requirements for privacy information were mapped to the elements of these codes, labelled as “Healthcare Workers’ Hand Hygiene Privacy Codes (HW-HH-PCs)”. Both ISO/IEC 27701 and ISO/IEC 29184 guidelines for Privacy Notices and consent were linked with the activities for preparing the code resources.

Findings

Components of an ISO/IEC 27701 system, the guidance of ISO/IEC 29184 and the definitions provided in ISO/IEC 29100 can assist the preparation of HW-HH-PCs and the required resources. An ISO/IEC 29184 Privacy Notice can be used as input for developing an Informed Consent Form, which can be implemented to suit two of the four developed HW-HH-PCs.

Practical implications

HW-HH-PCs and the supporting resources, which healthcare organizations could implement to potentially increase quality assurance of an automated HH monitoring service, are illustrated.

Originality/value

Integrative augmentation of ISO 10001:2018, ISO/IEC 27701:2019 and ISO/IEC 29184:2020 within an underlying framework from ISO/IEC 20000–1:2018 for information technology service, together with the related examples of privacy-related customer satisfaction codes and the corresponding resources, is introduced.

Assessment of Risk Factors for Coronavirus Disease-2019 in Healthcare Workers: A Case–Control Study

Background and aims

With the rise of coronavirus disease-2019 (COVID-19) cases globally, the infection among frontline healthcare workers (HCWs) escalates many folds. There is, however, limited literature from low middle-income countries regarding risk factors for COVID-19 infection in HCWs. We conducted a case–control study to evaluate the risk factors of COVID-19 infection to HCWs.

Materials and methods

This case–control study was conducted in a designated COVID-19 hospital. Eighty-one HCWs involved in direct care of COVID-19 patients, identified as cases, and 266 were recruited as controls. Telephonic interviews with participants were conducted, and information regarding demographic variables, chemoprophylaxis, exposure to infected patients, and adherence to infection prevention and control (IPC) measures was collected.

Results

We observed a statistically significant difference in the number of times training session for IPC measures attended by HCWs (p = 0.02), performance of aerosol-generating medical procedures (AGMPs) (p <0.001), practices of donning and doffing of personal protective equipment (PPE) (p <0.001), hand hygiene (p <0.001), and decontamination of highly touched surfaces (p <0.001). Logistic regression analysis revealed if the decontamination of highly touched surfaces is decreased by one unit, the odds of getting COVID-19 infection is multiplied by a factor of 0.41 and AGMPs decrease the risk of being a case by 0.76.

Conclusion

This study highlighted that inadequate observation of IPC methods increases the risk of COVID-19 infection to frontline HCWs, whereas performance of AGMPs does not enhance the risk. In this study, HCWs undertaking an AGMP, because of concern of acquiring infection, were more diligent during procedures and hence had lesser infection.

Electronic hand hygiene monitoring systems can be well-tolerated by health workers: Findings of a qualitative study

Background:

Electronic hand hygiene monitoring overcomes limitations associated with manual audit but acceptability to health workers varies and may depend on culture of the ward and the nature of the system.

Objectives:

Evaluate the acceptability of a new fifth type electronic monitoring system to frontline health workers in a National Health Service trust in the UK.

Methods:

Qualitative interviews with 11 informants following 12 months experience using an electronic monitoring system.

Results:

Informants recognised the importance of hand hygiene and embraced technology to improve adherence. Barriers to hand hygiene adherence included heavy workload, dealing with emergencies and ergonomic factors related to placement of alcohol dispensers. Opinions about the validity of the automated readings were conflicting. Some health workers thought they were accurate. Others reported problems associated with differences in the intelligence of the system and their own clinical decisions. Opinions about feedback were diverse. Some health workers thought the system increased personal accountability for hand hygiene. Others ignored feedback on suboptimal performance or ignored the data altogether. It was hard for health workers to understand why the system registered some instances of poor performance because feedback did not allow omissions in hand hygiene to be related to the context of care.

Conclusion:

Electronic monitoring can be very well tolerated despite some limitations. Further research needs to explore different reactions to feedback and how often clinical emergencies arise. Electronic and manual audit have complementary strengths.

Electronic Monitoring Systems for Hand Hygiene: Systematic Review of Technology

BACKGROUND

Hand hygiene is one of the most effective ways of preventing health care-associated infections and reducing their transmission. Owing to recent advances in sensing technologies, electronic hand hygiene monitoring systems have been integrated into the daily routines of health care workers to measure their hand hygiene compliance and quality.

OBJECTIVE

This review aims to summarize the latest technologies adopted in electronic hand hygiene monitoring systems and discuss the capabilities and limitations of these systems.

METHODS

A systematic search of PubMed, ACM Digital Library, and IEEE Xplore Digital Library was performed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Studies were initially screened and assessed independently by the 2 authors, and disagreements between them were further summarized and resolved by discussion with the senior author.

RESULTS

In total, 1035 publications were retrieved by the search queries; of the 1035 papers, 89 (8.60%) fulfilled the eligibility criteria and were retained for review. In summary, 73 studies used electronic monitoring systems to monitor hand hygiene compliance, including application-assisted direct observation (5/73, 7%), camera-assisted observation (10/73, 14%), sensor-assisted observation (29/73, 40%), and real-time locating system (32/73, 44%). A total of 21 studies evaluated hand hygiene quality, consisting of compliance with the World Health Organization 6-step hand hygiene techniques (14/21, 67%) and surface coverage or illumination reduction of fluorescent substances (7/21, 33%).

CONCLUSIONS

Electronic hand hygiene monitoring systems face issues of accuracy, data integration, privacy and confidentiality, usability, associated costs, and infrastructure improvements. Moreover, this review found that standardized measurement tools to evaluate system performance are lacking; thus, future research is needed to establish standardized metrics to measure system performance differences among electronic hand hygiene monitoring systems. Furthermore, with sensing technologies and algorithms continually advancing, more research is needed on their implementation to improve system performance and address other hand hygiene-related issues.

Assessing the accuracy of a new hand hygiene monitoring device (SmartRub®): from the laboratory to clinical practice

Background

We developed SmartRub® powered by iQati®, an electronic device composed of a wristband and an alcohol-based handrub pocket-sized dispenser that measures and provides feedback on the duration of hand friction and the volume poured during each hand hygiene action. We aimed to assess the accuracy of SmartRub®.

Methods

The specificity, sensitivity, positive and negative predictive values (PPV and NPV) of SmartRub® were assessed in a 3-phased experiment: (1) laboratory-controlled conditions with volunteers; (2) pre-planned clinical path with volunteers and (3) real clinical conditions with healthcare workers. The accuracy of SmartRub® was evaluated by quantifying its ability to correctly capture true hand hygiene actions and to not record other actions performed while wearing the device.

Results

In the laboratory, 7 volunteers performed 816 actions. Overall sensitivity was 94.1% (95% CI 91.4–96.2%) with a PPV of 99.0% (95% CI 97.3–99.6%) and specificity was 99.0% (95% CI 97.5–99.7%) with a NPV of 94.4% (95% CI 91.9–96.1%). During the pre-planned clinical path phase, 13 volunteers performed 98 planned paths and a total of 967 actions were performed. Overall sensitivity was 94.6% (95% CI 92.2–96.5%) with a PPV of 84.3% (95% CI 81.6–86.7%) and specificity was 82.4% (95% CI 78.7–85.7%) with a NPV of 93.9% (95% CI 91.3–95.7%). During the real clinical conditions phase, 17 healthcare workers were observed for a total of 15 h and 3 min while they performed 485 actions. Sensitivity was 96.8% (95% CI 93.8–98.6%) with a PPV of 98.3% (95% CI 95.6–99.3%) and specificity was 98.3% (95% CI 95.7–99.5%) with a NPV of 96.8% (95% CI 93.9–98.4%).

Conclusions

Smartrub® is a highly reliable device for capturing hand hygiene actions under a range of conditions, from the laboratory to clinical care activities.

How does innovative technology impact nursing in infectious diseases and infection control? A scoping review

AIM

Considering the increasing number of emerging infectious diseases, innovative approaches are strongly in demand. Additionally, research in this field has expanded exponentially. Thus, faced with this diverse information, we aim to clarify key concepts and knowledge gaps of technology in nursing and the field of infectious diseases.

DESIGN

This scoping review followed the methodology of scoping review guidance from Arksey and O'Malley.

METHODS

Six databases were searched systematically (PubMed, Web of Science, IEEE Explore, EBSCOhost, Cochrane Library and Summon). After the removal of duplicates, 532 citations were retrieved and 77 were included in the analysis.

RESULTS

We identified five major trends in technology for nursing and infectious diseases: artificial intelligence, the Internet of things, information and communications technology, simulation technology and e-learning. Our findings indicate that the most promising trend is the IoT because of the many positive effects validated in most of the reviewed studies.

Three-year hand hygiene monitoring and impact of real-time reminders on compliance

BACKGROUND

Hand hygiene remains both the major strategy and an ongoing challenge for infection control. The main issues in the sustainability of hand hygiene automatic monitoring are healthcare worker (HCW) turnover rates and declining participation.

AIM

To assess hand hygiene compliance and the impact of real-time reminders over three years.

METHODS

HCW compliance was observed for the use of alcohol-based hand rubs (AHR) on room entry and exit. Linear multi-level mixed models with time autocorrelations were performed to analyse the repeated measurements of daily room compliance and the effect of reminders over eight quarters (24 months).

FINDINGS

In all, 111 HCWs were observed and 525,576 activities were identified in the database. There was an improvement in compliance both on room entry and exit over two years, and the rooms which had activated reminders had better performance than the rooms which did not have activated reminders.

CONCLUSIONS

This study showed the benefit of using real-time reminders; even 20% of rooms with an activated reminder improved overall hand hygiene compliance. A randomized real-time reminder setting may be a potential solution in reducing user fatigue and enhancing HCW self-awareness.

Use of an automated hand hygiene compliance system by emergency room nurses and technicians is associated with decreased employee absenteeism

Few studies have examined the use of hand hygiene interventions among health care personnel and employee absenteeism. To improve the hand hygiene practices of emergency room nurses and technicians, we implemented mandatory use of an automated hand hygiene compliance system. After implementation, we found reductions in employee absenteeism and the number of overtime hours worked by substitute staff. These unanticipated results demonstrate a return on investment that benefits the health of employees.

Pitfalls and Unexpected Benefits of an Electronic Hand Hygiene Monitoring System

BACKGROUND

No single strategy is more effective than proper hand hygiene (HH) in reducing the spread of nosocomial infections. Unfortunately, health care worker compliance with HH is imperfect. We sought to improve HH compliance using an electronic hand hygiene monitoring system (EHHMS) in 2 units to collect unbiased data and provide feedback.

METHODS

In this prospective, quasi-experimental study, the Hyginex EHHMS was installed in 2 units at Tufts Medical Center. Ninety-one bracelets were assigned, and electronic data were collected over 8 months. Human observations continued. We compared HH compliance as measured by human observation before, during, and after EHHMS implementation. Pre- and post-implementation surveys were distributed to staff.

RESULTS

The number of electronically captured HH compliance observations was small due to infrequent bracelet use after month 2 of the intervention. HH compliance, as determined by human observation, increased by an average of 1.3 percentage points per month (P = .0005). Survey responses revealed negative attitudes about the EHHMS before and after its implementation.

CONCLUSIONS

Despite poor EHHMS participation and negative attitudes toward its implementation, HH compliance, as measured by human observation, significantly improved. Hospitals considering implementing an EHHMS should look to refine the intervention to encourage health care worker participation.

Current issues in hand hygiene

Although substantial improvements in hand hygiene practices have occurred in recent years, many health care facilities continue to encounter challenges in achieving and maintaining high levels of hand hygiene compliance. Issues of current interest include the optimum dose of alcohol-based handrub (ABHR) that should be applied, the impact of hand size and alcohol-based handrub dry times have on efficacy, and ideal hand hygiene technique. There is a need to determine which additional promotional activities can augment improvements in hand hygiene that are achieved by implementing the multimodal improvement strategy recommended by the World Health Organization. Monitoring hand hygiene performance and providing personnel with feedback on their performance are essential elements of successful improvement programs. Further research is needed to establish the most effective methods of providing feedback. Additional studies are needed to optimize strategies for performing direct observation of hand hygiene compliance, and to determine the role of supplementing direct observations using automated monitoring systems.

Strategies to improve hand hygiene compliance among healthcare workers in adult intensive care units: a mini systematic review

BACKGROUND

Hand hygiene compliance among healthcare workers (HCWs) in intensive care units (ICUs) is disconcertingly low.

AIM

To identify the effective intervention(s) for increasing HH compliance among HCWs in adult ICUs.

METHODS

Two major electronic databases, OVID Medline and CINAHL, were searched by using a combination of MeSH terms and text words (e.g. hand hygiene, hand washing, compliance, adher*, improve*, develop* and intensive care unit) for relevant articles. This was supplemented by Google Scholar and hand searching of included bibliographies. Data from identified articles were then abstracted, quality-assessed, and combined into a summary effect.

FINDINGS

Of 89 titles and abstracts that were identified, 14 articles were finally included. Overall study quality was good. However, variations in design, setting, sample size, and intervention(s) tested precluded a meta-analysis; hence a narrative synthesis was conducted. The interventions included education, observation, provision of supplies, improving access and directive support; tested singly or in combination; resulted in positive outcomes in all but one study. A combination of administrative support, 'supplies', education and training, reminders, surveillance, and performance feedback raised the compliance from a baseline of 51.5% to a record 80.1%; but no set of intervention(s) could improve the compliance to the desired near-100% level.

CONCLUSION

Available data suggest that multi-modal interventions are effective in raising the compliance to a 'plateau' level but not up to the desired standard. Methodologically appropriate trials of combined interventions could enhance the evidence about interventions to improve hand hygiene compliance among ICU staff.
