The Feedback Intervention Trial (FIT) — Improving Hand-Hygiene Compliance in UK Healthcare Workers: A Stepped Wedge Cluster Randomised Controlled Trial
Achieving a sustained improvement in hand-hygiene compliance is the WHO's first global patient safety challenge. There is no RCT evidence showing how to do this. Systematic reviews suggest feedback is most effective and call for long term well designed RCTs, applying behavioural theory to intervention design to optimise effectiveness.
Three year stepped wedge cluster RCT of a feedback intervention testing hypothesis that the intervention was more effective than routine practice in 16 English/Welsh Hospitals (16 Intensive Therapy Units [ITU]; 44 Acute Care of the Elderly [ACE] wards) routinely implementing a national cleanyourhands campaign). Intervention-based on Goal & Control theories. Repeating 4 week cycle (20 mins/week) of observation, feedback and personalised action planning, recorded on forms. Computer-generated stepwise entry of all hospitals to intervention. Hospitals aware only of own allocation.
direct blinded hand hygiene compliance (%).
All 16 trusts (60 wards) randomised, 33 wards implemented intervention (11 ITU, 22 ACE). Mixed effects regression analysis (all wards) accounting for confounders, temporal trends, ward type and fidelity to intervention (forms/month used). INTENTION TO TREAT ANALYSIS: Estimated odds ratio (OR) for hand hygiene compliance rose post randomisation (1.44; 95% CI 1.18, 1.76;p<0.001) in ITUs but not ACE wards, equivalent to 7-9% absolute increase in compliance. PER-PROTOCOL ANALYSIS FOR IMPLEMENTING WARDS: OR for compliance rose for both ACE (1.67 [1.28-2.22]; p<0.001) & ITUs (2.09 [1.55-2.81]; p<0.001) equating to absolute increases of 10-13% and 13-18% respectively. Fidelity to intervention closely related to compliance on ITUs (OR 1.12 [1.04, 1.20]; p = 0.003 per completed form) but not ACE wards.
Despite difficulties in implementation, intention-to-treat, per-protocol and fidelity to intervention, analyses showed an intervention coupling feedback to personalised action planning produced moderate but significant sustained improvements in hand-hygiene compliance, in wards implementing a national hand-hygiene campaign. Further implementation studies are needed to maximise the intervention's effect in different settings.

Electronic Monitoring Systems for Hand Hygiene: Systematic Review of Technology
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.
This review aims to summarize the latest technologies adopted in electronic hand hygiene monitoring systems and discuss the capabilities and limitations of these systems.
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.
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%).
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.

Simplifying the World Health Organization Protocol
In an experimental setting, a simplified, 3-step hand hygiene technique for applying alcohol-based hand rub was non inferior in terms of reduction of bacterial counts, as compared to the conventional World Health Organization 6-step technique. We therefore compared compliance and microbiological efficacy between both hand hygiene techniques in routine clinical practice.
We performed a cluster-randomized trial from October-November 2015 at the University Hospital Basel, Switzerland: a tertiary, academic care center (ISRCTN45923734). We randomly assigned 12 wards to either the 3-step technique or the conventional 6-step technique of hand rubbing. The primary endpoints were compliance with the assigned technique and reduction of bacterial counts on the hands of health-care workers.
Overall, 2923 hand hygiene indications were observed, and compliance was 70.7% (2066/2923). Compliance with technique and indications was 51.7% (595/1151) and 75.9% (1151/1516) on wards assigned to the 3-step technique, respectively, as compared to 12.7% (116/915) and 65.0% (915/1407) on wards assigned to the 6-step technique (P < .001). The reduction factor (RF) of bacterial colony counts did not differ between techniques (median RF 0.97 log10 colony-forming units [CFU] [interquartile range 0.39-1.59] for the 3-step technique vs median RF 1.04 log10 CFU [interquartile range 0.49-1.52] for the 6-step technique; P = .629).
In a clinical setting, the simpler hand hygiene technique, consisting of 3 steps, resulted in higher compliance with both hand hygiene indications and technique, as compared to the 6 steps. As the results of the microbiological analyses exclude inferiority, the conventional 6 steps could be safely replaced by a simpler hand hygiene technique.

Application of the behaviour-centred design to understand facilitators and deterrents of hand hygiene among healthcare providers: findings from a formative phase of a cluster randomised trial in the Kampala Metropolitan area
Background
Hand hygiene is known to reduce healthcare-associated infections. However, it remains suboptimal among healthcare providers. In this study, we used the Behaviour-centered Design approach to explore the facilitators and deterrents to hand hygiene among healthcare providers in the Kampala Metropolitan area, Uganda.
Methods
We conducted a formative qualitative study as part of a cluster randomised trial in 19 healthcare facilities (HCFs). The study used 19 semi-structured and 18 key informant interviews to collect data on hand hygiene status and facilitators and deterrents of hand hygiene. Research assistants transcribed verbatim and used a thematic framework aided by Nvivo 14.0. to undertake analysis. We used thick descriptions and illustrative quotes to enhance the credibility and trustworthiness of our findings.
Results
About 47.4% of the HCFs had sufficient hand hygiene infrastructure, and 57.9% did not report total compliance with hand hygiene during patient care. The physical facilitator for hand hygiene was the presence of constant reminders such as nudges, while the biological included the frequency of patient contact and the nature of clinical work. The only biological deterrent was the heavy workload in HCFs. The executive brain facilitators included knowledge of workplace health risks, infection prevention and control (IPC) guidelines, and a positive attitude. A negative attitude was the executive brain deterrent to hand hygiene. Recognition, rewards, and fear of infections were the only motivated brain facilitators. Behavioural setting facilitators included proximity to functional hand hygiene infrastructure, the existence of active IPC committees, good leadership, and the availability of a budget for hand hygiene supplies. Behavioural setting deterrents included the non-functionality and non-proximity to hand hygiene infrastructure and inadequate supplies.
Conclusions
The study revealed low compliance with hand hygiene during the critical moments of patient care and inadequacy of hand hygiene infrastructure. The deterrents to hand hygiene included a heavy workload, negative attitude, inadequate supplies, non-functionality, and long distance to hand washing stations. Facilitators included constant reminders, fear of infections, frequency of patient contact and nature of clinical work, positive attitude, knowledge of IPC guidelines, recognition and reward, good leadership, availability of budgets for hand hygiene supplies, availability and proximity to hand hygiene supplies and infrastructure and active IPC committees.

Kotter’s 8-step change model to improve hand hygiene compliance in intensive care unit: A 41-month prospective longitudinal quality improvement study
Despite numerous studies assessing bundled interventions to enhance hand hygiene compliance (HHC), compliance rates persist at suboptimal levels. Our objective was to employ Kotter’s Change Model (KCM) to enhance HHC and conduct a comprehensive process evaluation among medical staff within the intensive care unit (ICU).
KCM was implemented at the ICU of Zhongnan Hospital of Wuhan University from March 2018 to August 2021, with a 41-month longitudinal monitoring of HHC. The primary outcome focused on the absolute monthly change in HHC. Secondary outcomes encompassed the HHC characteristics across different phases, varying trends in HHC concerning different hand hygiene opportunities and occupations, quarterly incidences of central line-associated bloodstream infections (CLABSI) and catheter-associated urinary tract infections (CAUTI).
This study included 20,222 hand hygiene actions and 24,195 opportunities. The overall HHC was 83.58 % (95 %CI, 83.11 %-84.04 %). Following the KCM implementation, HHC surged from 35.71 % (95 % CI, 22.99 %–50.83 %) to 87.75 % (95 % CI, 85.53 %–89.67 %), reflecting a notable increase of 145.73 %. The most rapid growth in HHC occurred post-patient contact, elevating from 35.29 % to 89.8 %. Despite escalating patient numbers and treatment complexities annually, the quarterly rates of CLABSI (0 ‰–3.53 ‰) and CAUTI (0.96 ‰-4.26 ‰) remained consistently low.
Utilizing KCM systematically alters healthcare providers’ perception of hand hygiene, fostering an environment that advocates for and sustains improved HHC among ICU personnel.
The Kotter’s change model can be an effective framework for healthcare organizations to systematically improve and maintain hand hygiene compliance among healthcare providers, which can in turn help reduce healthcare-associated infections.

A systematic review on the causes of the transmission and control measures of outbreaks in long-term care facilities: Back to basics of infection control
The unique characteristics of long-term care facilities (LTCFs) including host factors and living conditions contribute to the spread of contagious pathogens. Control measures are essential to interrupt the transmission and to manage outbreaks effectively.
The aim of this systematic review was to verify the causes and problems contributing to transmission and to identify control measures during outbreaks in LTCFs.
Four electronic databases were searched for articles published from 2007 to 2018. Articles written in English reporting outbreaks in LTCFs were included. The quality of the studies was assessed using the risk-of-bias assessment tool for nonrandomized studies.
A total of 37 studies were included in the qualitative synthesis. The most commonly reported single pathogen was influenza virus, followed by group A streptococcus (GAS). Of the studies that identified the cause, about half of them noted outbreaks transmitted via person-to-person. Suboptimal infection control practice including inadequate decontamination and poor hand hygiene was the most frequently raised issue propagating transmission. Especially, lapses in specific care procedures were linked with outbreaks of GAS and hepatitis B and C viruses. About 60% of the included studies reported affected cases among staff, but only a few studies implemented work restriction during outbreaks.
This review indicates that the violation of basic infection control practice could be a major role in introducing and facilitating the spread of contagious diseases in LTCFs. It shows the need to promote compliance with basic practices of infection control to prevent outbreaks in LTCFs.

Baseline Characteristics of a Cluster Randomized Controlled Trial Targeting Hand Hygiene in Primary Healthcare in Burkina Faso and Mali
This study presents baseline characteristics of a cluster randomized controlled trial (cRCT) on hand hygiene in primary healthcare in Burkina Faso and Mali, addressing data gaps on hand hygiene practices in these settings.
We implemented a two-arm cRCT in 48 primary healthcare facilities. Baseline data were collected (January-June 2023), followed by covariate-constrained randomization. We conducted covert hand hygiene observations, hand-rinse sampling for
detection, and a survey on behavioral factors among healthcare workers. The primary outcome is observed handwashing rate.
Baseline data included 309 healthcare workers. Trial arms were balanced in hand hygiene adherence, behavioral factors, and
contamination. Hand hygiene adherence was low (12%).
contamination was very high in Burkina Faso (76%) and considerable in Mali (23%). Participants had a high intention to wash their hands (93%) but only a quarter could name all moments for hand hygiene.
Poor hand hygiene and
contamination in our setting may heighten nosocomial infection risks. Interventions should address knowledge and build on high intentions to perform hand hygiene.
