HAND HYGIENE COMPLIANCE IN THE PREVENTION OF HOSPITAL ACQUIRED INFECTIONS: A SYSTEMATIC REVIEW

Respiratory infectious disease transmission of dental healthcare workers

Respiratory pathogens significantly impact public health, with transmission primarily occurring during close contact. Dental healthcare workers (HCWs) are particularly at high risk due to long-term mouth opening of patients, and frequent close proximity between HCWs and patients. This study systematically analyzed close contact patterns in 200 dental procedures in mainland China's specialized dental settings, developing a mechanistic model to quantify exposure doses and infection risks for HCWs treating patients with respiratory infections. Findings revealed that the infection risks among dentists are 5.0-fold that among assistants, underscoring the need for enhanced protective measures. Infection risks for assistants were significantly impacted by patient age, especially in cases involving patients under 14 years, while disease type influenced risks for both dentists and assistants, with higher risks in prosthodontics and orthodontics. The assessments of protective measures for HCWs showed that combining N95 respirators with face shields provided over 95 % protection, while N95 respirators alone conferred over 89 % protection, suitable for high-risk settings. Face shields with surgical masks offered over 75 % protection, providing a cost-effective alternative in resource-limited environments. These results emphasize the importance of tailoring protective strategies to specific risk factors, offering valuable guidance for infection control practices in specialist-based dental healthcare systems. ENVIRONMENTAL IMPLICATION: This study addresses the environmental challenge of respiratory pathogen transmission in specialist-based dental healthcare systems. Through mechanistic modeling based on real close-contact behaviors from 200 dental procedures, dentists face 5.0-fold higher infection risks than assistants, with prosthodontics and orthodontics presenting high risks. The findings emphasize the necessity of targeted protective measures, recommending N95 respirators with face shields for optimal protection and surgical masks with face shields as cost-effective alternatives. By tailoring infection control strategies to specific risks, this study offers practical insights to enhance occupational safety and mitigate pathogen transmission in specialist-based dental environments.

Targeted next-generation sequencing enhances precision and rapid detection in healthcare-associated infection Surveillance: Unveiling multidrug-resistant colonization in ICUs

Objectives

This study aims to evaluate the potential advantages of targeted next-generation sequencing (tNGS) over conventional bacterial culture methods for pathogen detection in hospital-associated infections (HAIs).

Methods

All EICU medical staff and all medical staff from the Physical Examination Centre completed a questionnaire. Nasopharyngeal specimens were collected from medical staff who met all of the inclusion criteria and none of the exclusion criteria. EICU medical staff provided 2 samples each, while Physical Examination Centre staff provided 1 sample each. For EICU medical staff, one of their two nasopharyngeal swabs was subjected to tNGS testing, and the other to bacterial culture testing. For the PEC staff, their nasopharyngeal swabs were subjected to tNGS testing. Additionally, six pairs of spectacles and six keyboards used by EICU medical staff were randomly selected, and the surfaces were swabbed with sterile swabs for tNGS testing.

Results

In 23 nasal swab samples from EICU group, tNGS detected 14 species of microorganism in 29 instances within 19 h. Bacterial culture detected 2 species of microorganism in 4 instances, 2 positive samples within 19 h and confirmed another 2 positive samples within 69 h. A total of 42 samples with 14 different microorganism species were collected from the nasopharyngeal swabs of 23 EICU members and 15 PEC members. Among them, 29 cases (69 %) of 14 different microorganisms were detected in EICU staff, with an average of 1.3 microorganism species detected per person, while 13 cases (28 %) of 6 different microorganisms were detected in PEC staff, with an average of 0.9 microorganism species detected per person. The most common colonizing bacteria included Staphylococcus aureus, Acinetobacter baumannii, and Klebsiella spp. Compared to bacterial culture, tNGS offers advantages in monitoring HAIs, including a broad range of detectable microorganisms, high sensitivity of results, and shorter reporting time for positive results. Bacteria colonizing the EICU carry more antibiotic resistance genes.

Conclusions

tNGS outperforms conventional culture in healthcare-associated infection surveillance, with higher sensitivity and accelerated pathogen identification. Simultaneously, tNGS revealed extensive colonization of multidrug-resistant (MDR) pathogens (e.g., Acinetobacter baumannii, MRSA) in EICU environments, highlighting its utility in monitoring complex antimicrobial resistance patterns.

Analysis of Hospital-Acquired Infections in a Chinese Specialized Rehabilitation Hospital: A Five-Year Surveillance Study (2020-2024)

Objective

Hospital-acquired infections (HAIs) pose significant challenges in rehabilitation hospitals, particularly affecting patients with extended stays and complex medical needs. This study analyzed HAI patterns and risk factors in a Chinese rehabilitation hospital from 2020 to 2024.

Methods

A retrospective observational study was conducted at a tertiary-care rehabilitation hospital with 25 specialized wards. Data collection included patient demographics, clinical parameters, and ward-level characteristics. Statistical analysis employed Poisson and Quasi-Poisson regression models to identify risk factors, with comprehensive diagnostic evaluation.

Results

The study revealed an overall infection rate of 3.64%, representing 385 infections among 10,559 inpatients. The Vegetative State Awakening Department exhibited the highest infection rate at 11.1%, followed by Geriatric Rehabilitation Department (8.2%), and Neuro Rehabilitation Department wards (5.5-7.0%). Respiratory tract infections were most common (42%), with ventilator-associated pneumonia accounting for 28% of all infections. Statistical analysis identified several significant risk factors through both Poisson and Quasi-Poisson regression models. In the more reliable Quasi-Poisson model that accounted for overdispersion, tracheal intubation emerged as the strongest predictor with a coefficient of 2.02 (p < 0.001), followed by use of glucocorticoids (coefficient: 1.78, p < 0.001). While the initial Poisson model suggested a protective effect of radiation therapy, this effect was not significant in the Quasi-Poisson model.

Conclusion

The study highlights the critical role of tracheal intubation and glucocorticoid use in HAI development within rehabilitation settings. The significant ward-level variability in infection rates suggests the need for tailored infection control strategies. Implementation of targeted interventions focusing on these identified risk factors could help reduce HAI incidence in rehabilitation hospitals.

Visualizing the WHO "My Five Moments for Hand Hygiene," framework: A virtual reality training program for improving hand hygiene adherence among nurses

BACKGROUND

Health care-associated infections (HAIs) contribute to patient morbidity and mortality. Hand hygiene is essential for preventing HAIs, but training can fail to transfer to clinical practice. Experiential learning through virtual reality (VR) may improve adherence by offering realistic practice opportunities and feedback.

METHODS

We developed and evaluated a VR-based training program that uses the World Health Organization's (WHO) "My Five Moments for Hand Hygiene" framework to provide feedback about pathogen transmission and hand hygiene adherence in 4 clinical scenarios. Sixty-eight registered nurses from 4 hospitals in the United States completed the VR training program. Using the Theory of Planned Behavior, we assessed behavioral determinants (intention, attitudes, subjective norms, and perceived behavioral control [self-efficacy]) of hand hygiene adherence pre-, midway, and post training. We also measured overall adherence to the Five Moments in each scenario.

RESULTS

From the beginning to the end of the training program, self-efficacy scores and overall hand hygiene adherence in VR increased linearly by 11% (P=.02) and 68% (P<.001), respectively.

CONCLUSIONS

Our findings support VR as an educational tool for enhancing hand hygiene practices of health care workers. Future research should assess the transfer of training to clinical settings and its impact on real-world adherence and HAIs.

Uncovering the obstacles: a comprehensive analysis of barriers to hand hygiene adherence among healthcare providers: a systematic review

BACKGROUND

Hand hygiene is the most effective and feasible infection prevention and control measure within the healthcare facilities. Despite the ease and simplicity of the technique, the adherence rate among health professionals remains suboptimal. Hence, developing targeted interventions to improve adherence requires a clear understanding of these obstacles. Therefore, this systematic reviews of existing literature aims to fully understand the context specific barriers of hand hygiene to answer why barriers persisted despite the interventions to maintaining hand hygiene practices among healthcare providers.

METHODS

This systematic review was conducted to synthesize existing evidence according to the Joanna Briggs Institute (JBI) qualitative studies review methodology on qualitative studies publish between the year 2010 and 2024. The study is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guideline (PRISMA) and the protocol for the study was published on PROSPERO (CRD42024573753) before commencing the study.

RESULT

The review included twenty eight studies that are conducted in different regions of the world representing six of the continents. The study identified four interconnected themes of barriers with many subthemes. Behavioural barriers and organizational barriers were the most highlighted themes within the review. Physical barriers were one of the significant themes, where unavailability and inconvenience of hand hygiene resources gain the most attention by study participants across the studies. The fourth theme was societal/interpersonal barriers characterized by negative social influence and unsupportive colleagues.

CONCLUSION

The study highlights that the barriers to hand hygiene adherence among healthcare professionals are intertwined and complex, with the main interplaying among behavioural, societal/interpersonal, physical, and organizational barriers. The findings underscore that the intertwined nature of these barriers requires a multifaceted approach involving the relevant stakeholders to improve hand hygiene adherence among healthcare providers.

Spreading of hand hygiene change package across an acute hospital

BACKGROUND

A set of interventions in a hand hygiene change package was developed in a pilot ward by the end of 2017. In 2018, Changi General Hospital embarked on scaling up the change package to other wards with the intention to eventually spread the hand hygiene change package hospital-wide.

METHODS

Changi General Hospital conducted a quality improvement project on hand hygiene with the intention to effect organisation-wide improvement in hand hygiene. Spread methodologies such as the Institute for Healthcare Improvement's framework for Spread and various complementary spread concepts such as having an organisational strategy, which plans for spread as early as possible, and addressing social aspects of change were applied in order to scale up and spread a change package.

SETTING

A general tertiary care hospital in Singapore.

RESULTS

Overall hospital-wide hand hygiene compliance improved from a median of 66% during the pilot phase to 73% in the scale-up phase (p<0.05) to 82% during the spread phase (p<0.05).

CONCLUSIONS

A systematic approach to hand hygiene improvement based on spread literature successfully improved and sustained hospital-wide hand hygiene compliance. Success factors included the development of a change package that had clear guiding principles, with the intent to create proactive learning cycles within units which could be adapted to work in various contexts.

Evaluation of the Content, Reliability, and Quality of YouTube Videos on Surgical Hand Scrubbing

The purpose of this study was to evaluate the content, reliability, and quality of YouTube videos on surgical hand scrubbing. Two hundred videos in English were identified and screened according to the inclusion criteria. The evaluation of the sample of 72 videos was guided by content, reliability, and quality tools. Videos with at least one source in the description had significantly greater reliability scores than those without (t = 3.871, P < .001). There were no significant differences between the content scores and the general traits of the videos (eg, advertisements, subtitles). Analysis of the relationship between the content and quality scores with the video traits showed a weak positive correlation between quality scores and video length (r = 0.233, P = .049). Viewers should consider content, reliability, and quality rather than popularity when seeking educational video content on hand scrubbing.

Patient Hand Hygiene Before Meals: A Systematic Review

BACKGROUND

Hand hygiene is recognized as an effective way to prevent health care-associated infections (HAIs). However, there is limited attention to patient hand hygiene (PHH).

PURPOSE

The purpose of this systematic review was to summarize evidence, interventions, and outcomes of PHH before meals.

METHODS

Literature was searched from 1999 to 2024 in 4 databases. The Grading of Recommendations, Assessment, Development, and Evaluation was used to appraise the strength of evidence.

RESULTS

Ten reports were included in the review. Five categories of PHH interventions were identified: direct observation, reminders, education, policy change, and bundles of more than one intervention. There is insufficient evidence to establish a direct causal link between PHH before meals and a reduction in HAIs.

CONCLUSIONS

The limited and moderate level of evidence highlights a significant gap in understanding PHH. Hand hygiene is a fundamental infection prevention strategy that warrants additional research in hospitalized patient populations to determine the clinical efficacy and causal effects on HAIs.

Leveraging agents of change to improve the use of an electronic hand hygiene monitoring system

BACKGROUND

We evaluated the effectiveness of an "agents of change" intervention in enhancing hand hygiene compliance (HHC) with an electronic hand hygiene monitoring system (EHHMS), and improving perceptions of the EHHMS among health care workers.

METHODS

Two intervention units and 1 control unit were selected. Thirteen agents received training, then worked independently on the intervention units to improve their colleagues' perceptions and behaviors toward the EHHMS. Agents and unit health care workers were surveyed before and after the intervention to measure perceptions of the EHHMS and impact of the intervention. HHC was electronically monitored across all units 8weeks before, 5weeks during, and 8weeks after the intervention.

RESULTS

Postintervention, 70% of agents believed they influenced their colleagues' behaviors, but 50% felt they changed attitudes. Unit-level surveys confirmed minimal change in attitudes and culture. Average HHC rates increased by 6.8% and 5% in the intervention units during the intervention (both P<.01), whereas the control did not. One intervention unit maintained improvement in the post period, whereas the other returned to baseline. Compliance rates for all units were similar in the post period.

CONCLUSIONS

Implementing an agents of change program to target EHHMS compliance is feasible, but sustained improvement is less certain.

Development of the initial Leapfrog Group's hand hygiene standard

BACKGROUND

Health care-associated infections (HAIs) remain a major concern in US hospitals, contributing to significant patient mortality and medical costs. Studies indicate that up to 70% of HAIs are preventable, with proper hand hygiene the most effective method of preventing transmission. Despite this, adherence to hand hygiene in hospitals remains low.

METHODS

This article describes the process of developing, testing, and refining a standard to improve hand hygiene adherence in US hospitals. Building on the published literature and guidance from a national expert panel, Leapfrog developed a standard with 5 key domains.

RESULTS

In 2019, 1,698 hospitals pilot tested an initial set of survey questions intended to measure hospital performance against the hand hygiene standard. Responses were not scored, but reviewed to make refinements. The scoring of hospital responses to the survey questions and the public reporting of hospitals' performance on meeting the hand hygiene standard began in 2020. From 2020 to 2023, the percentage of reporting hospitals that have met each domain of the hand hygiene standard and fully achieved Leapfrog's hand hygiene standard continued to grow.

CONCLUSIONS

Leapfrog's hand hygiene standard provides hospitals with a "how-to guide" for best practices to promote hand hygiene and prevent HAIs.

Integration of an electronic hand hygiene auditing system with electronic health records using machine learning to predict hospital-acquired infection in a health care setting

BACKGROUND

Hospital-acquired infections (HAIs) increase morbidity, mortality, and health care costs. Effective hand hygiene (HH) is crucial for prevention, but achieving high compliance remains challenge. This study explores using machine learning to integrate an electronic HH auditing system with electronic health records to predict HAIs.

METHODS

A retrospective cohort study was conducted at a Brazilian hospital during 2017-2020. HH compliance was recorded electronically, and patient data were collected from electronic health records. The primary outcomes were HAIs per CDC/National Healthcare Safety Network surveillance definitions. Machine learning algorithms, balanced with Random Over Sampling Examples (ROSE), were utilized for predictive modeling, including generalized linear models (GLM); generalized additive models for location, scale, and shape (GAMLSS); random forest; support vector machine; and extreme gradient boosting (XGboost).

RESULTS

125 of 6,253 patients (2%) developed HAIs and 920,489 HH opportunities (49.3% compliance) were analyzed. A direct correlation between HH compliance and HAIs was observed. The GLM algorithm with ROSE demonstrated superior performance, with 84.2% sensitivity, 82.9% specificity, and a 93% AUC.

CONCLUSIONS

Integrating electronic HH auditing systems with electronic health records and using machine learning models can enhance infection control surveillance and predict patient outcomes. Further research is needed to validate these findings and integrate them into clinical practice.

Promoting hand hygiene in a chemotherapy day center: the role of a robot

BACKGROUND

Hand hygiene is a critical component of infection prevention in healthcare settings. Innovative strategies are required to enhance hand hygiene practices among patients and healthcare workers (HCWs).

METHODS

This study was conducted at the Chemotherapy Day Center of Queen Mary Hospital, Hong Kong. It comprised three phases: phase 1 involved observational audits of hand hygiene practices among patients and HCWs by infection control nurse (ICN); phase 2 included the installation of 53 pressure sensors on alcohol-based hand rub (AHR) bottles at designated sites to monitor usage; phase 3 introduced the robot named Temi Medic to promote hand hygiene through video broadcasts at strategic locations in the center. The mean counts of pressure sensor-equipped AHR per 100 attendances per day (hereafter referred to as the mean count) across phases 2 and 3 were analyzed.

RESULTS

A total of 2580 patient attended the center from April to September 2023. The ICN observed a significant increase in hand hygiene practices among patients at the entrance and reception area, rising from phase 1 (0.2%, 1/583) and phase 2 (0.5%, 3/656) to phase 3 (5.0%, 33/654) (p < 0.001). Meanwhile, the overall hand hygiene compliance among HCWs was 74.1% (1341/1810) throughout the study period. From phase 2 to phase 3, the mean counts of 7 AHR bottles designated for patient use (P1-P7) significantly increased (35 ± 17 vs. 64 ± 24, p < 0.001), as did the 33 AHR bottles shared by both patients and HCWs (207 ± 104 vs. 267 ± 113, p = 0.027). In contrast, there was no significant change in the mean count among the 13 AHR bottles designated for HCWs (H1-H13). The mean count of H1-H13 was significantly higher than that of P1-P7 throughout phases 2 and 3 (214 ± 93 vs. 49 ± 25, p < 0.001), indicating a 4.4-fold difference.

CONCLUSIONS

While HCWs maintained stable hand hygiene compliance, the introduction of the robot significantly improved hand hygiene practices among patients in the chemotherapy day center. This underscores the importance of integrating technology into routine practices to promote infection prevention and control in healthcare settings.

Hospital Context Determinants of Variability in Healthcare-Associated Infection Prevalence: Multi-Level Analysis

Healthcare-associated infections (HAIs) represent a major challenge in patient safety that affects services disproportionally. This paper aimed to assess how the HAI prevalence varies between hospital services and what contextual characteristics may explain such variance. A cross-sectional study was conducted on adult patients in Portuguese hospitals, using data from the European point prevalence survey of HAI prevalence. The study variables included patient, structural, and process variables, tested as risk factors, with patients clustered in hospitals. Variables with a p-value ≤ 0.2 in univariate analyses were retested in a multivariable model. A total of 18,261 patients from 119 hospitals were included: 736 from 56 intensive care units (ICUs), 3160 from 72 surgical departments, and 8081 from 90 medical departments. The HAI prevalence was 7.9%, 5.9%, and 1.7%, respectively. In ICUs, only the number of devices was associated with the HAI prevalence. In surgical departments, age, comorbidities, being a specialized hospital, and a higher ratio of infection prevention and control (IPC) personnel were associated with higher SSI. The safety climate was associated with lower SSI. In medical departments, age and devices were positively associated, whereas a larger ratio of IPC nurses was negatively associated. These results may help implement targeted interventions to achieve optimal results in each department.

Improving Antimicrobial Utilization and Infection Control in Ophthalmology: An Information-Assisted Transparent Supervision and Multidisciplinary Team Model

Background

Using antimicrobials wisely is crucial for effective treatment and reducing antimicrobial resistance (AMR). As ocular infections can lead to serious consequences and ophthalmic surgery has a great impact on patients, the application of antimicrobials in ophthalmology needs to be managed in a standardized manner.

Methods

A multidisciplinary team (MDT) on antimicrobial stewardship was set up by adopting comprehensive management measures and a continuous improvement model with all-staff training and empowerment, information-assisted medical prescription control, and transparent supervision.

Results

After intervention, the antibiotics use density, antibiotics utilization rate and antibiotics prophylactic utilization rate for type I incision operation among inpatients decreased from 30.02%, 49.64% and 58.04% in 2018 to 8.78% (decrease by 70.77%), 18.31% (p < 0.001) and 8.93% (p < 0.001) in 2022, respectively; the microbiological submission rate related to antibiotics utilization, etiological submission rate before antibiotic therapy and before combined use of key antibiotics rose from 13.44%, 17.39% and 50.00% to 27.33% (p < 0.001), 51.3% (p < 0.001) and 100.00% (increase by 100%), respectively; the incidence of nosocomial infection and surgical site infection for type I incision operation both reduced to zero, while the use of hand hygiene products markedly increased. For pathogen detection, a total of 489 pathogens were isolated from 2018 to 2022, of which 69.30% were Gram-positive bacteria, 26.02% were Gram-negative bacteria, and 4.68% were fungi. Ocular secretion was the main detection site (89.31%). Antibiotic resistance analysis results indicated that Staphylococci maintained complete sensitivity to linezolid, vancomycin, and teicoplanin. Streptococcus pneumoniae maintained complete sensitivity to vancomycin, benzathine, levofloxacin, and moxifloxacin, with resistance to penicillin G and ceftriaxone down to zero.

Conclusion

Multidisciplinary team and information-assisted transparent supervision have displayed obvious effects in promoting the standardized application of antimicrobials in ophthalmology, via distinctly improving indicators relevant to antimicrobial application and nosocomial infection. Our work may provide guidance for improving the medical quality and curbing the AMR.

The economic burden of nosocomial infections for hospitals: evidence from Germany

BACKGROUND

Nosocomial infections (NI) significantly worsen patient outcomes, resulting in higher mortality rates and reduced health-related quality of life. Furthermore, they pose substantial economic strain on healthcare systems and hospitals. For instance, patients with nosocomial infections (NIs) experience prolonged hospital stays compared to those without NIs. These extended stays result in occupied bed-days, leading to opportunity costs for hospitals. This study aimed to estimate the opportunity costs for a German hospital based on hospital stays, daily revenue, and occupancy rates (OCR).

METHODS

We analysed cost data obtained from routine records maintained by the accounting department of a German hospital's surgical and orthopedic units from 2018 to 2019 for the "HygArzt" research project. To ensure balance, we employed genetic matching. We estimated the differences in length of stay (LOS) and daily revenue between patients with and without nosocomial infections (NI) using linear regression. Finally, we calculated the opportunity cost borne by the hospital by treating NI patients instead of non-NI patients. All costs are reported in 2018 Euros.

RESULTS

The final sample included 81 patients with NI matched with 207 patients without NI. The majority of the NI patients (77.0%) had surgical site infection (SSI). Compared to non-NI patients, we observed that NI patients had a longer LOS (10 days, p < 0.001) and lower daily revenue (€400, p < 0.001). We also found that comorbidities and the frequency of operations had significant impact on the LOS. Using a baseline 30 to 50% preventable NIs, successful prevention of a single NI could potentially reduce the length of hospital stay by 3 to 5 days and increase hospital revenue by approximately €120 to €200 per day per prevented NI. Consequently, the hospital saves 3 to 5 more bed-days to backfill and generate more revenue, and/or make more efficient resource allocation by changing bed-capacity and staffing. The resulting opportunity costs can potentially exceed €1,000 per preventable case.

CONCLUSION

NIs pose a substantial economic burden for hospitals. From a health economics' perspective, there are strong economic incentives for hospitals to implement infection control interventions, such as the involvement of a prevention link physician/nurse.

Trends in the hand hygiene practices using alcohol-based hand rubs in Japanese hospitals before and after the novel coronavirus pandemic: an observational study using national surveillance data

BACKGROUND

Healthcare-associated infections (HAIs) are a global concern in healthcare facilities, and hand hygiene (HH) using alcohol-based hand rubs (ABHR) is fundamentally crucial for their prevention. While previous studies report improvements in HH compliance amid the COVID-19 pandemic, the real situation in Japanese medical settings remains unclear.

METHODS

This observational study sought data from the Japanese national surveillance, focusing on ABHR use in hospitals before and after the COVID-19 pandemic. Data were retrieved from facilities certified to receive the Additional Healthcare Reimbursements for Infection Prevention and Control I. The study spanned five years (2019-2023), segmented quarterly, and employed Joinpoint regression analysis to assess the annual percentage change (APC).

RESULTS

Overall, ABHR use per patient per day significantly increased both in critical care units and general wards amid the pandemic. However, the APC in the critical care units demonstrated a downward trend from Q4 of 2021 to Q1 of 2023, and ABHR use in general wards remained below the amount of WHO recommendations.

CONCLUSION

This trend analysis highlighted recent patterns of ABHR use in Japanese hospitals by comparing pre- and post-COVID-19 periods. Although increases in ABHR use were observed over time, sustained efforts to promote HH compliance are necessary, particularly in general wards.

A clinical trial evaluation of handwashing products and educational resources to improve hand hygiene in paediatric patients and school children

Introduction

It is widely acknowledged that good hand hygiene (HH) is an important non-pharmaceutical method for reducing the transmission of infectious diseases. Children are at high risk of infection due to their immature immune systems. Hospital transmitted infections are a cause for concern worldwide, with poor HH suggested to be responsible for up to 20% of cases. Patients, in particular paediatric patients, are often overlooked when it comes to the promotion of hand hygiene compliance (HHC) in hospitals. This report describes the clinical evaluation of the 'Soaper Stars'; a collection of child-friendly HH products with linked educational resource, developed using the COM-B approach to behaviour change, and designed to encourage correct HH in paediatric patients and in schools.

Method

The Soaper Star products were distributed on paediatric wards in five UK hospitals, and the use of the products around mealtimes was evaluated. Workshops teaching the 'why when and how' of handwashing were run in four UK primary schools with pre and post evaluations conducted to establish impact on knowledge. Over 300 children were involved.

Results

The Soaper Stars products stimulated a 38% increase in HHC compared to when only hospital-issued products were available, and verbal feedback from families indicated that having the Soaper Star products encouraged improved HHC by all visitors, not just the patient. Workshops in four schools (283 pupils) showed an increase in knowledge around the transmission of infection and the need for good HH that was sustained for at least 4 weeks.

Conclusion

The results of this study demonstrate that providing children with the age-appropriate knowledge about why HH is necessary, and the child-friendly means to maintain their HH, will lead to greater HHC, not just by individual children, but also their families.

Hand hygiene compliance in nursing home wards: The effects of feedback with lights on alcohol-based hand rub dispensers

BACKGROUND

Hand hygiene (HH) among health care workers (HCWs) is crucial in preventing infections in nursing homes. However, HH compliance (HHC) among HCWs remains low. This study aimed to investigate the effect of feedback lights on HCWs' HHC.

METHODS

A 5-month interventional study was conducted in 3 wards in a nursing home in Denmark. During the intervention period, a green light with a smiley appeared on the alcohol-based hand rub (ABHR) dispensers when HCWs used the ABHR, acknowledging HCWs for using the ABHR. HHC was monitored using an automatic HH monitoring system (AHHMS).

RESULTS

A total of 64 HCWs were enrolled. The AHHMS collected 23,696 HH opportunities in apartments and dirty utility rooms. Overall, HHC in the apartments increased from 50% at baseline (95% CI: 48, 53) to 56% (95% CI: 54, 58) during the intervention. However, the increased HHC level was not sustained during follow-up.

CONCLUSIONS

The AHHMS enabled the assessment of the intervention. We found a significant effect of light-guided feedback in the apartments. However, the increased HHC was not sustained after the light was switched off.

Indication-based and patient-based hand hygiene performance among nurses working at a university hospital

The traditional method of monitoring hand hygiene (HH) based on specific indications does not ensure that HH is performed for all required indications during patient care. This study aimed to compare HH performance rates (HHPRs) based on specific indications versus overall patient care among nurses at a university hospital. The study retrospectively analyzed HH monitoring data for 1398 indications from 543 patients and 190 nurses. Observations were conducted continuously, tracking a single healthcare worker from before patient contact until the end of the contact within a 30-min period. The indication-based HHPR was found to be 89.1%, while the patient-based HHPR was 78.1%. In the context of patient-based HHPR, the lowest rates were observed among nurses in the emergency room (48.3%) and those with less than 1 year of work experience (66.7%). Moreover, the largest discrepancy between indication-based and patient-based HHPR was noted among emergency room nurses with less than 1 year of experience. This significant difference underscores the need for patient-based HH monitoring, particularly for nurses in emergency settings and those with limited experience.

Effect of a multimodal prevention strategy on dialysis-associated infection events in outpatients receiving haemodialysis: The DIPS stepped wedge, cluster-randomized trial

OBJECTIVES

Patients with haemodialysis catheters are susceptible to dialysis-associated infections, particularly bloodstream infections. There have been few systematic attempts to reduce this burden. Our study aimed to investigate the effect of a multimodal prevention strategy on dialysis-associated infection events (DAIE) among haemodialysis outpatients.

METHODS

A multicentre, stepped wedge, cluster-randomized controlled trial was done from October 2019 to September 2021. Outpatient dialysis facilities entered into the intervention phase in three randomly assigned clusters, at three predefined time points. The multimodal prevention strategy consisted of infection surveillance and hand hygiene (HH) compliance observation with active feedback and teaching aseptic procedures, and a patient flyer. The primary outcome was incidence rates of different DAIE, such as bloodstream infections, intravenous antimicrobial starts, and local access-site infections per 1000 dialysis. As secondary outcome, we analysed the HH compliance change.

RESULTS

A total of 43 haemodialysis outpatient facilities with 11 251 patients and 1 413 457 proceeded haemodialysis were included in the DIPS-trial. Incidence rates were 0.71 DAIE per 1000 dialysis (95% CI, 0.65-0.78) in the control and 0.31 (95% CI, 0.27-0.36) in the intervention group. The univariable analysis yielded an incidence rate ratio (IRR) of 0.44 (95% CI, 0.33-0.59) for DAIE. Especially in patients with a central venous catheter, we saw a significant decrease in DAIE in the intervention group (IRR 0.4; 95% CI, 0.28-0.58). The HH observation combined with feedback and intensified training, resulted in an increase of HH compliance from 58-65%.

DISCUSSION

A multimodal prevention strategy showed a significant preventive effect on DAIE among haemodialysis outpatients. This reduction also applied to bloodstream infections, especially in patients with a central venous catheter.

An Analysis of the Contaminants on Otoscopes of Otolaryngology Residents: An Observational Study

The study was conducted to learn if the otoscope, a noncritical medical device, used by ENT residents harbor pathogenic organism. This study was conducted in a medical teaching hospital in India. Total of 38 otoscopes of ENT residents were examined after taking samples using sterile cotton swabs from otoscope speculum and otoscope head and both bacterial and fungal culture were studied. The study showed that 11 otoscope heads (28.94%) and 11 otoscope speculums (28.94%) out of the 38 otoscopes studied showed bacterial growth. Most commonly isolated bacteria were skin commensals followed by Klebsiella species. Fungal growth was seen in 3 out of 38 otoscope Speculums (7.89%). All 3 fungi isolated during the study belonged to Aspergillus species. Training residents regarding hygiene of medical equipments is necessary. Residents must be periodically assessed regarding their practice in handling medical equipments.

Process Evaluation of an Acute-Care Nurse-Centred Hand Hygiene Intervention in US Hospitals

This paper describes a process evaluation of a 'wise' intervention that took place in six acute care units in two medical-surgical teaching hospitals in the United States during 2016-2017. 'Wise' interventions are short, inexpensive interventions that depend on triggering specific psychological mechanisms to achieve behaviour change. This study sought to increase the hand hygiene compliance (HHC) rates before entering a patient's room among nurses. The intervention centred on the use of threat to professional identity to prompt improved HHC. Through questionnaires administered to intervention participants and the implementation facilitator, together with independent observation of intervention delivery, we examined whether the steps in the Theory of Change occurred as expected. We found that aspects of the implementation-including mode of delivery, use of incentives, and how nurses were recruited and complied with the intervention-affected reach and likely effectiveness. While components of the intervention's mechanisms of impact-such as the element of surprise-were successful, they ultimately did not translate into performance of the target behaviour. Performance was also not affected by use of an implementation intention as repeated performance of HHC over years of being a nurse has likely already established well-ingrained practices. Context did have an effect; the safety culture of the units, the involvement of the Nurse Managers, the level of accountability for HHC in each unit, and the hospitals themselves all influenced levels of engagement. These conclusions should have implications for those interested in the applicability of 'wise' interventions and those seeking to improve HHC in hospitals.

Diabetes and infection: review of the epidemiology, mechanisms and principles of treatment

An association between diabetes and infection has been recognised for many years, with infection being an important cause of death and morbidity in people with diabetes. The COVID-19 pandemic has re-kindled an interest in the complex relationship between diabetes and infection. Some infections occur almost exclusively in people with diabetes, often with high mortality rates without early diagnosis and treatment. However, more commonly, diabetes is a complicating factor in many infections. A reciprocal relationship occurs whereby certain infections and their treatments may also increase the risk of diabetes. People with diabetes have a 1.5- to 4-fold increased risk of infection. The risks are the most pronounced for kidney infection, osteomyelitis and foot infection, but are also increased for pneumonia, influenza, tuberculosis, skin infection and general sepsis. Outcomes from infection are worse in people with diabetes, with the most notable example being a twofold higher rate of death from COVID-19. Hyperglycaemia has deleterious effects on the immune response. Vascular insufficiency and neuropathy, together with altered skin, mucosal and gut microbial colonisation, contribute to the increased risk of infection. Vaccination is important in people with diabetes although the efficacy of certain immunisations may be compromised, particularly in the presence of hyperglycaemia. The principles of treatment largely follow those of the general population with certain notable exceptions.

Infection Control Measure Performance in Long-Term Care Hospitals and Their Relationship to Joint Commission Accreditation

BACKGROUND

This study evaluated the relationship between Joint Commission accreditation and health care-associated infections (HAIs) in long-term care hospitals (LTCHs).

METHODS

This observational study used Centers for Medicare & Medicaid Services (CMS) LTCH data for the period 2017 to June 2021. The standardized infection ratio (SIR) of three measures used by the Centers for Disease Control and Prevention's National Healthcare Safety Network were used as dependent variables in a random coefficient Poisson regression model (adjusting for CMS region, owner type, and bed size quartile): catheter-associated urinary tract infections (CAUTIs), Clostridioides difficile infections (CDIs), and central line-associated bloodstream infections (CLABSIs) for the periods 2017 to 2019 and July 1, 2020, to June 30, 2021. Data from January 1 to June 30, 2020, were excluded due to the COVID-19 pandemic.

RESULTS

The data set included 244 (73.3%) Joint Commission-accredited and 89 (26.7%) non-Joint Commission-accredited LTCHs. Compared to non-Joint Commission-accredited LTCHs, accredited LTCHs had significantly better (lower) SIRs for CLABSI and CAUTI measures, although no differences were observed for CDI SIRs. There were no significant differences in year trends for any of the HAI measures. For each year of the study period, a greater proportion of Joint Commission-accredited LTCHs performed significantly better than the national benchmark for all three measures (p = 0.04 for CAUTI, p = 0.02 for CDI, p = 0.01 for CLABSI).

CONCLUSION

Although this study was not designed to establish causality, positive associations were observed between Joint Commission accreditation and CLABSI and CAUTI measures, and Joint Commission-accredited LTCHs attained more consistent high performance over the four-year study period for all three measures. Influencing factors may include the focus of Joint Commission standards on infection control and prevention (ICP), including the hierarchical approach to selecting ICP-related standards as inputs into LTCH policy.

A cluster of Candida parapsilosis displaying fluconazole-trailing in a neonatal intensive care unit successfully contained by multiple infection-control interventions

Objective

This study aimed to investigate and contain a cluster of invasive candidiasis cases caused by fluconazole-resistant Candida parapsilosis (FRC) in a neonatal intensive care unit.

Methods

Active surveillance was initiated. Direct observations of hand-hygiene compliance (HHC) among staff were conducted before and after the implementation of hand-hygiene (HH) education. Thirty-five environmental cultures were obtained. Phylogenetic analysis of FRC was performed using Fourier-transform infrared spectroscopy and microsatellite genotyping.

Results

A total of 14 patients (mean birth weight = 860 g, gestational age = 25 weeks) infected with FRC were identified using the fully automated analyzer, including 5 with clinical infection (three with catheter-related bloodstream infection, one with cutaneous infection, and one with fatal peritonitis) and 9 with colonization. The HHC rate in nurses before performing a sterile or aseptic procedure significantly improved after the HH education (P < .05). Sinks near the patients were contaminated with FRC. All FRC strains were confirmed to be susceptible to fluconazole using the CLSI method, and the microdilution procedure indicated a trailing effect. Phylogenetic analysis showed that all the fluconazole-trailing isolates from patients were clustered together and had the same genotype. Sinks were successfully decontaminated using accelerated hydrogen peroxide and drainage pipes were replaced. Ultraviolet-C decontamination was applied in the milk preparation room. No new cases were detected after the education and disinfection interventions.

Conclusions

Sinks are an important reservoir of C. parapsilosis. Active surveillance, environmental hygiene, and constant staff education on maintaining a high level of HHC are necessary to limit the spread of C. parapsilosis.

Rinse, gel, and foam - is there any evidence for a difference in their effectiveness in preventing infections?

BACKGROUND

Following publication of the 2009 World Health Organizations Guidelines for Hand Hygiene in Health Care, a debate has emerged regarding the relative antimicrobial efficacy of the different formats (rinse, gel, foam) of ABHRs and their ability to contribute to reduction of healthcare-associated infections (HAIs).

METHODS

Data regarding the in-vivo antimicrobial efficacy of ABHRs and other factors that likely affect their effectiveness in reducing HAIs were reviewed, and a comprehensive review of studies that reported the effectiveness of each of the three ABHR formats to improve hand hygiene compliance and reduce HAIs was conducted.

RESULTS

The amount of rubbing time it takes for hands to feel dry (dry time) is the major driver of ABHR antimicrobial efficacy. ABHR format is not a major factor, and several studies found that rinse, gel, and foam ABHRs have comparable in-vivo antimicrobial efficacy. Other factors that likely impact the ability of ABHRs to reduce transmission of healthcare-associated pathogens and HAIs include ABHR formulation, the volume applied to hands, aesthetic characteristics, skin tolerance, acceptance by healthcare personnel, and hand hygiene compliance rates. When accompanied by complementary strategies, promoting the use of each of the three ABHR formats has been associated with improvements in hand hygiene compliance rates. A review of 67 studies failed to identify an ABHR format that was significantly more effective in yielding statistically significant reductions in transmission of healthcare-associated pathogens or HAIs.

CONCLUSIONS

Current evidence is insufficient to definitively determine if one ABHR format is more effective in reducing transmission of healthcare-associated pathogens and HAIs. More rigorous studies such as multicenter randomized controlled trials comparing the different formats are needed to establish if one format is significantly more effective in reducing HAIs.

Hand hygiene compliance in nursing home wards: the effect of increased accessibility of alcohol-based hand rub

BACKGROUND

Elderly nursing home residents are vulnerable to infection from micro-organisms. Hand hygiene is considered one of the most important measures to prevent transmission.

AIM

To determine the effect of increased accessibility to alcohol-based hand rub (ABHR) in nursing home wards by monitoring hand hygiene compliance (HHC) among healthcare workers (HCWs).

METHODS

An 11-month intervention study was conducted in a Danish six-ward nursing home. Data were collected using an automatic hand hygiene monitoring system (AHHMS). After a baseline period, one extra ABHR dispenser was placed in each of the 150 apartments. Baseline HHC was compared with the HHC during an immediate intervention period and a long-term intervention period.

FINDINGS

A total of 159 HCWs were included. The AHHMS registered 341,078 hand hygiene opportunities. Overall baseline HHC was 31% (95% confidence interval: 30-32). A significant +18% absolute immediate effect (first five months) (95% CI: 17-19; P < 0.0001) and +13 percentage points (95% CI: 11-14; P < 0.0001) long-term effect (another four months) were recorded. HCWs working day shifts and short-term employees had a higher baseline HHC than HCWs working evening/night shifts. However, HCWs working night shifts achieved the greatest long-term effect with a mean +27 percentage point difference (P < 0.0001).

CONCLUSION

Placing an additional ABHR dispenser strategically within staff workflow significantly increased HHC among HCWs, demonstrating a noteworthy effect. The study is the first to report the effect on nursing home dispenser accessibility as a single intervention and to show a significant unmet potential.

Knowledge and Training Needs in Nosocomial Infection among Hospital Staff in the City of Kielce, Poland: A Cross-Sectional Study

Introduction

Nosocomial infections are an integral part of health care services, posing a threat to both patients and medical staff. The duty and role of nursing staff is to prevent nosocomial infections in every hospitalized person. Material and Methodology. The study involved 635 nurses working in various surgical and conservative wards. The technique used was the author's questionnaire, which contained 30 questions and was divided into three components.

Results

The level of knowledge among the surveyed nurses was at a sufficient level for more than half of the total tested population, and its level was influenced by two variables: the specialization held and the level of education. Nurses working in medical wards have a higher level of knowledge in the area of basic concepts related to nosocomial infections, and people who use specialist medical literature and participate in specialist courses have a sufficient level of knowledge. The shortest time since the last training results in a higher level of knowledge and a higher level of knowledge in the area covering the basic concepts of nosocomial infections. The most frequently selected issues on which nurses would like to expand their knowledge were post-exposure procedures and methods of monitoring nosocomial infections.

Conclusions

The knowledge of the nursing staff in the field of nosocomial infections is diverse, and its main determinants are specialization, education, and age. A sufficient level of knowledge among the respondents is conditioned primarily by the use of specialist literature and participation in specialist courses, which determine both the scope and area of knowledge on nosocomial infections.

Nursing students led simulations to improve healthcare workers' hand hygiene compliance

BACKGROUND

Hand hygiene compliance (HHC) is recognised as a major factor in the prevention of healthcare-associated infections. Healthcare workers (HCWs) compliance is still suboptimal. Simulation as an educational strategy may contribute to improved performance.

OBJECTIVE

This study aimed to assess the effect of simulation interventions led by nursing students on HCWs' HHC.

METHOD

A prospective quasi-experimental design with before and after intervention measurements was implemented in an 1150-bed tertiary hospital. Four consecutive periods, measuring before and after HHC, were examined in four hospital divisions. For each division, unique simulation activities were developed and led by nursing students, educators, and hospital leaders. Sixty seven students and 286 healthcare workers, along with two nurse educators, participated in the simulation sessions. HHC of all HCWs in the divisions was assessed by hospital infection control personnel.

RESULTS

Hospital HHC rose across the four periods in all four divisions during this study. In three out of four periods and divisions, HHC increased significantly more in the simulation intervention groups compared to the overall hospital improvement.

CONCLUSION

Student-led simulation for HCWs is an additional effective method to improve HHC. Nursing managers should consider joining forces with nursing educators to enable students to become agents of change in healthcare settings and encourage further collaboration.

Harnessing of Artificial Intelligence for the Diagnosis and Prevention of Hospital-Acquired Infections: A Systematic Review

Healthcare-associated infections (HAIs) are the most common adverse events in healthcare and constitute a major global public health concern. Surveillance represents the foundation for the effective prevention and control of HAIs, yet conventional surveillance is costly and labor intensive. Artificial intelligence (AI) and machine learning (ML) have the potential to support the development of HAI surveillance algorithms for the understanding of HAI risk factors, the improvement of patient risk stratification as well as the prediction and timely detection and prevention of infections. AI-supported systems have so far been explored for clinical laboratory testing and imaging diagnosis, antimicrobial resistance profiling, antibiotic discovery and prediction-based clinical decision support tools in terms of HAIs. This review aims to provide a comprehensive summary of the current literature on AI applications in the field of HAIs and discuss the future potentials of this emerging technology in infection practice. Following the PRISMA guidelines, this study examined the articles in databases including PubMed and Scopus until November 2023, which were screened based on the inclusion and exclusion criteria, resulting in 162 included articles. By elucidating the advancements in the field, we aim to highlight the potential applications of AI in the field, report related issues and shortcomings and discuss the future directions.

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.

Effects of light-guided nudges on health care workers' hand hygiene behavior

BACKGROUND

Hospital-acquired infections are the most frequent adverse events in health care and can be reduced by improving the hand hygiene compliance (HHC) of health care workers (HCWs). We aimed to investigate the effect of nudging with sensor lights on HCWs' HHC.

METHODS

An 11-month intervention study was conducted in 2 inpatient departments at a university hospital. An automated monitoring system (Sani NudgeTM) measured the HHC. Reminder and feedback nudges with lights were displayed on alcohol-based hand rub dispensers. We compared the baseline HHC with HHC during periods of nudging and used the follow-up data to establish if a sustained effect had been achieved.

RESULTS

A total of 91 physicians, 135 nurses, and 15 cleaning staff were enrolled in the study. The system registered 274,085 hand hygiene opportunities in patient rooms, staff restrooms, clean rooms, and unclean rooms. Overall, a significant, sustained effect was achieved by nudging with lights in relation to contact with patients and patient-near surroundings for both nurses and physicians. Furthermore, a significant effect was observed on nurses' HHC in restrooms and clean rooms. No significant effect was found for the cleaning staff.

CONCLUSIONS

Reminder or feedback nudges with light improved and sustained physicians' and nurses' HHC, and constitute a new way of changing HCWs' hand hygiene behavior.

Evaluation of a novel surface-coating formulation with time-extended antimicrobial activity for healthcare environment disinfection

BACKGROUND

The importance of environmental contamination in the transmission of pathogens among hospitalized patients is universally recognized, and disinfection of surfaces is a widely accepted modality for reducing healthcare-associated infections. Nevertheless, hospital disinfection is still suboptimal. In this study, we evaluated the sustained effects of the novel formulation OxiLast™ which extends the antimicrobial effects of chlorine-based disinfectants.

METHODS

In an experimental lab phase, PVC surfaces were coated with OxiLast™ and then inoculated with representative Gram-positive and Gram-negative pathogenic bacteria. Cells were recovered at different contact times (5, 15, 30 min) to assess the reduction in bacterial counts compared to uncoated surfaces and also subject to various challenges to assess robustness. A similar methodology was then applied in an unoccupied hospital room to evaluate the sustained effect of OxiLast™ on high-touch surfaces.

RESULTS

OxiLast™ demonstrated notable activity against the range of bacterial strains tested with ≥ 4 log10 reduction in bacterial counts observed for up to seven days following one surface application, for various strains and contact times. Similar results were observed following challenges such as simulated abrasion of coated surfaces, organic contamination or successive inoculations. The results were confirmed in a simulated patient care environment.

CONCLUSIONS

The addition of OxiLast™ to common chlorine-based disinfectants has shown a substantial and sustained reduction in bacterial pathogen counts for up to 7 days following one application. The consistent results in the laboratory and hospital are promising and should be tested in a real-life clinical scenario.

Nurses' Adherence to the Portuguese Standard to Prevent Catheter-Associated Urinary Tract Infections (CAUTIs): An Observational Study

Urinary tract infections are among the most prevalent types of healthcare-associated infections (HAIs) in hospitals and nursing homes, and they are primarily a result of unnecessary catheter usage and inadequate care. In Portugal, epidemiological data indicate that catheter-associated urinary tract infections (CAUTIs) remain widespread in clinical settings, resulting in increased morbidity and mortality rates among vulnerable populations. This study aimed to assess urinary catheter use in an oncology ward in Portugal and to evaluate nurses' adherence to the government-endorsed standards for preventing CAUTIs. An observational study was conducted over a four-month period with daily assessments of nurses' practices during urinary catheter insertion and maintenance using a government-endorsed auditing tool. Data were collected through on-site observations and nurses' feedback. The findings revealed a urinary catheter utilization rate of 17.99%. However, there was a lack of complete adherence to government-endorsed standards among oncology nurses (0%). These results indicate that current practices lack evidence-based standardization. Therefore, there is a need to develop and implement quality improvement initiatives to enhance patient safety and experiences.

Using spectral characterization to identify healthcare-associated infection (HAI) patients for clinical contact precaution

Healthcare-associated infections (HAIs) are a major problem in hospital infection control. Although HAIs can be suppressed using contact precautions, such precautions are expensive, and we can only apply them to a small fraction of patients (i.e., a limited budget). In this work, we focus on two clinical problems arising from the limited budget: (a) choosing the best patients to be placed under precaution given a limited budget to minimize the spread (the isolation problem), and (b) choosing the best patients to release when limited budget requires some of the patients to be cleared from precaution (the clearance problem). A critical challenge in addressing them is that HAIs have multiple transmission pathways such that locations can also accumulate 'load' and spread the disease. One of the most common practices when placing patients under contact precautions is the regular clearance of pathogen loads. However, standard propagation models like independent cascade (IC)/susceptible-infectious-susceptible (SIS) cannot capture such mechanisms directly. Hence to account for this challenge, using non-linear system theory, we develop a novel spectral characterization of a recently proposed pathogen load based model, 2-MODE-SIS model, on people/location networks to capture spread dynamics of HAIs. We formulate the two clinical problems using this spectral characterization and develop effective and efficient algorithms for them. Our experiments show that our methods outperform several natural structural and clinical approaches on real-world hospital testbeds and pick meaningful solutions.

Factors associated with hand washing effectiveness: an institution-based observational study

BACKGROUND

Few studies have investigated how the effectiveness of hand washing in removing hand contaminants is influenced by the performance and duration of each step involved. We conducted an observational study by recruiting participants from a university campus, with the aim to comprehensively evaluate how performance, duration and demographic factors influence hand washing effectiveness.

METHODS

A total of 744 videos were collected from 664 participants in July-October 2022 and independently evaluated by two infection control experts through labelling videos for correct and incorrect performance of each step. The individual hand washing effectiveness was determined by quantifying the percentage of residual fluorescent gel on the dorsum and palm areas of each participant's hands. A logistic regression analysis was conducted to identify factors that were significantly associated with better hand washing effectiveness. An exposure-response relationship was constructed to identify optimal durations for each step. Approximately 2300 hand images were processed using advanced normalization algorithms and overlaid to visualize the areas with more fluorescence residuals after hand washing.

RESULTS

Step 3 (rub between fingers) was the most frequently omitted step and step 4 (rub the dorsum of fingers) was the most frequently incorrectly performed step. After adjustment for covariates, sex, performance of step 4 and step 7 (rub wrists), rubbing hands during rinsing, and rinsing time were significantly associated with hand washing effectiveness. The optimal overall hand washing time was 31 s from step 1 to step 7, and 28 s from step 1 to step 6, with each step ideally lasting 4-5 s, except step 3. The palms of both hands had less fluorescence residuals than the dorsums. The areas where residuals most likely appeared were wrists, followed by finger tips, finger webs and thumbs.

CONCLUSIONS

Performance and duration of some hand washing steps, sex and rinsing time were associated with hand washing effectiveness. The optimal duration might be applied to all seven steps to achieve the best decontamination results. Further studies are needed to refine hand hygiene standards and enhance compliance.

Effectiveness of educational and training intervention for improving hand hygiene compliance amongst nurses: a systematic review and meta-analysis of randomised controlled trials

BACKGROUND AND AIMS

Developing and implementing an educational and training programmes for improving hand hygiene compliance of the nursing personnel might help in increasing their knowledge, promoting positive attitude and follow adequate practice measures.

MATERIAL AND METHODS

Systematic search was done in PubMed, SCOPUS, CENTRAL, EMBASE, ScienceDirect, Clinicaltrials.gov and Google Scholar databases for articles published between 1964 and December 2022. Meta-analysis was carried out using a random-effects model, and the results were reported as pooled risk ratio (RR) with 95% confidence intervals (CIs), pooled standardised mean differences (SMD) or risk ratios (RR).

RESULTS

Eight studies were included in the analysis. Most studies had higher risk of bias. Nurses receiving educational and training programmes had significantly higher compliance to hand hygiene practices (pooled RR of 1.69 [95% CI: 1.23-2.31; I2  =  99.1%], p  =  0.001). The pooled analysis based on studies reporting the compliance to hand hygiene as continuous outcome has reported the pooled SMD as 1.28 with 95% CI: 0.62 to 1.95 and I2  =  74.5%. There were no single-study effects with respect to this outcome, since the sensitivity analysis showed no difference in either direction or strength of effect estimate.

CONCLUSION

Educational and training programmes are effective in improving the hand hygiene compliance amongst the nursing professionals.

Microbiological Analysis of Surgeons' Hands in a Public Hospital in São Luis, Maranhão State, Brazil: A Cross-Sectional Study

Antisepsis of the hands of medical personnel is one of the most important steps in the process of patient care, since direct contact can cause the cross-transfer of potentially pathogenic microorganisms at surgical sites. This study aimed to analyze the prevalence of microorganisms on the hands of 131 surgeons in a university hospital before the surgical procedure. Swabs were collected from each clinician's hands before and after handwashing. The samples were placed in a transport medium and immediately delivered to a private clinical analysis laboratory from São Luis-Maranhão. The microorganisms were identified by ionization source mass spectrometry and matrix-assisted laser desorption (MALDI-TOF), and antibiotic susceptibility tests (AST) were performed using the Vitek2 and Phoenix-BD automated system. The results showed a high frequency (100%) of microorganisms before handwashing, but after surgical antisepsis, the rate dropped significantly (p < 0.05) to 27.5%. The gram-positive species most detected were Staphylococcus spp. and Micrococcus luteus, representing 83.9%, followed by gram-negative species, Stenotrophomonas maltophilia, Acinetobacter baumanii, Pseudomonas aeruginosa, Pseudomonas gessardi, Pantoea septica, Serratia marcescens, and Burkholderia lata. The effectiveness of hand antisepsis was 72.5%, demonstrating that surgeons' hands are an important source of microorganisms that can cause infections in hospitalized patients in different care settings.

Compliance with hand hygiene practices and its appropriateness among healthcare workers during COVID-19 pandemic in public health facilities of Tamil Nadu, India

BACKGROUND

Compliance with appropriate hand hygiene practises is the most efficient and cost-effective intervention that can be implemented in the healthcare setting. Given its importance, we tried to capture the compliance with hand hygiene practises and their appropriateness among healthcare workers during the COVID-19 pandemic in public health facilities in Tamil Nadu.

METHODS

This cross-sectional study involved doctors, nurses, and allied healthcare professionals from various departments in 18 public healthcare facilities spanning six districts in Tamil Nadu. A random-intercept model was employed for the multivariable logistic regression analysis to evaluate the factors influencing hand hygiene compliance and its adequacy. The effect size was presented as an adjusted odds ratio (aOR) accompanied by a 95% confidence interval (CI).

RESULTS

In total, 2733 hand hygiene observations were made. Only during 19.4% (95%CI: 17.9%-20.9%) of these observations, hand washing was done. Only during 37.9% (95%CI: 33.9%-42.1%) of these observations, hand washing was done appropriately by following all the essential steps of hand hygiene. Nurses (aOR = 2.49; 95%CI: 1.90-3.26), healthcare workers in General Surgery (aOR = 2.18; 95%CI: 1.53-3.10) and Obstetrics & Gynaecology departments (aOR = 1.75; 95%CI: 1.26-2.43), working in inpatient departments (aOR = 2.64; 95%CI: 1.38-5.04) had significantly higher compliance to hand hygiene practices. Nurses (aOR = 2.58; 95%CI: 1.33-5.01) and General Medicine department healthcare workers (aOR = 1.98; 95%CI: 1.09-3.61) had significantly higher compliance to appropriate hand hygiene practices.

CONCLUSION

Our study shows that only during one-fifth of the observations did healthcare workers do hand washing, and less than 10% did it appropriately by following all the essential steps of hand hygiene.

Reducing Carbapenem-Resistant Enterobacteriaceae Using the Targeted Solution Tool: A Quality Improvement Project

BACKGROUND

Carbapenem-resistant Enterobacteriaceae (CRE) is a worldwide urgent health problem. Hand hygiene (HH) is an effective intervention to reduce the spread of CRE.

LOCAL PROBLEM

In 2017, an increase in the rate of health care-associated (HA) CRE colonization was observed in a large multiorgan transplant center in Italy. This study aimed to reduce the HA-CRE colonization rates by improving HH compliance.

METHODS

A pre-/post-intervention project was conducted from November 2017 through December 2020.

INTERVENTIONS

The DMAIC (Define, Measure, Analyze, Improve, and Control) framework was used to implement the HH Targeted Solution Tool (TST).

RESULTS

Hand hygiene compliance increased from 49% to 76.9% after the Improve phase ( P = .0001), and to 81.9% after the second Control phase ( P = .0001). The rate of HA-CRE decreased from 24.9% to 5.6% ( P = .0001).

CONCLUSIONS

Using the DMAIC framework to implement the TST can result in significant improvements in HH compliance and HA-CRE colonization rates.

A feasibility study of the use of medical clowns as hand-hygiene promoters in hospitals

Healthcare-acquired infections (HAI) pose vast health and economic burdens. Proper hand-hygiene is effective for reducing healthcare-acquired infections (HAI) incidence, yet staff compliance is generally low. This study assessed the feasibility, acceptability and preliminary effect of employing medical clowns to enhance hand-hygiene among physicians and nurses. Staff perception of the intervention and its impact on hand-hygiene was assessed via self-report questionnaires. Nearly 1,500 hand-hygiene compliance observations were conducted in accordance with WHO guidelines before, during and after the intervention. In each of three hospitals in Israel, two departments were selected-one in which medical clowns routinely operate and one clown-naive department. Professional medical clowns acted as hand-hygiene promoters employing humorous tactics to encourage hand-sanitizing based on the WHO "5 Moments" model. The clown appeared in each department seven times during the 2-week intervention phase. Pre-intervention hand-hygiene compliance ranged from just over 50% to 80% across hospitals and departments. Overall, about 70% of nurses (N = 132) and 80% of physicians (N = 49) felt the intervention improved personal and departmental hand-hygiene, with large inter-department variation. Pre- to post-intervention hand-hygiene compliance increased by 4% -25% (3.5-14.8 percentage points) in four departments, three of which had low baseline compliance levels. Results of this feasibility study suggest that employing medical clowns as hand-hygiene promoters as a novel approach toward HAI prevention is feasible and welcome by hospital staff.

Compliance with hand hygiene practices among nursing staff in secondary healthcare hospitals in Kuwait

Background

Hand hygiene (HH) among healthcare workers, especially nurses, is the main preventive measure to control healthcare associated infections but compliance with hand hygiene (CwHH) remains low in various settings including Kuwait. This study aimed to assess the knowledge of, attitudes towards, and CwHH among nursing staff in secondary care hospitals in Kuwait.

Methods

A cross-sectional study was conducted on nursing staff in all six secondary care hospitals in Kuwait. Data on knowledge of, attitudes towards, and self-reported CwHH were collected through a self-administered questionnaire that was developed based on WHO’s questionnaire, while the data on actual compliance were objectively collected through direct observation of nurses during routine care by two independent observers using WHO’s observation form.

Results

Of 829 nurses approached, 765 (92.2%) responded and participated. Of all participants, 524 (68.5%) were able to list “My Five Moments for Hand Hygiene” fully and appropriately. However, several misconceptions (e.g. air circulation in hospital is the main route of infection) about HH were found among the nurses. CwHH was (25.0%) by direct observation while self-reported compliance was (69.5%) each varied significantly (p < 0.001) between different hospitals. Female nurses compared to male nurses and non-Arab compared to Arab nationalities were more likely to report CwHH in multivariable analysis. Several items on knowledge of and attitudes towards HH were also associated with self-reported CwHH.

Conclusion

Observed CwHH among nursing staff in secondary care hospitals in Kuwait was low, which highlights the need to make more efforts to improve HH practices. Interventions that have been used elsewhere and found to be effective may be tested in Kuwait. Despite the good overall knowledge on HH among nurses, there are several misconceptions that need to be corrected.

Assessment of dental health care personnel protocol deviations and self-contamination during personal protective equipment donning and doffing

BACKGROUND

Dental health care personnel (DHCP) may be at increased risk of exposure to severe acute respiratory syndrome coronavirus 2, the virus that causes COVID-19, as well as other clinically important pathogens. Proper use of personal protective equipment (PPE) reduces occupational exposure to pathogens. The authors performed an assessment of PPE donning and doffing practices among DHCP, using a fluorescent marker as a surrogate for pathogen transmission.

METHODS

Participants donned PPE (that is, disposable gown, gloves, face mask, and eye protection) and the fluorescent marker was applied to their palms and abdomen. DHCP then doffed PPE according to their usual practices. The donning and doffing processes were video recorded, areas of fluorescence were noted, and protocol deviations were assessed. Statistical analyses included frequency, type, and descriptions of protocol deviations and factors associated with fluorescence.

RESULTS

Seventy DHCP were enrolled. The donning and doffing steps with the highest frequency of protocol deviations were hand hygiene (66% of donning and 78% of doffing observations involved a deviation) and disposable gown use (63% of donning and 60% of doffing observations involved a deviation). Fluorescence was detected on 69% of DHCP after doffing, most frequently on hands. An increasing number of protocol deviations was significantly associated with increased risk of fluorescence. DHCP with a gown doffing deviation, excluding doffing out of order, were more likely to have fluorescence detected.

CONCLUSIONS

DHCP self-contamination was common with both donning and doffing PPE.

PRACTICAL IMPLICATIONS

Proper use of PPE is an important component of occupational health.

The effect of compliance to Hand hygiene during COVID-19 on intestinal parasitic infection and intensity of soil transmitted helminthes, among patients attending general hospital, southern Ethiopia: Observational study

BACKGROUND

Intestinal parasitic infection (IPIs) is one of the major health problems in Sub -Saharan Africa where water, sanitation and hygiene practices are inadequate. Taking into account the national level implementation of intensive hand hygiene against COVID-19 pandemic and general protective effect this study assessed its effect on intestinal parasite.

OBJECTIVE

This study aim to investigate the effect of compliance to hand hygiene practice on the prevalence of intestinal parasitic infection (IPIs) and intensity of Soil transmitted helminthes (STH) among patients attending tertiary care hospital in southern Ethiopia.

METHODS

Observational study was conducted from June to September 2021. Data on socio demographic, hand hygiene practice and intestinal parasite (prevalence and intensity of helminthic infection) was collected from randomly selected and consented patients. Compliance to hand hygiene practice was assessed using pre-tested questionnaire. Fresh stool sample from each participant was examined by direct wet mount, concentration and Ziehl-Neelson (ZN) staining technique to detect intestinal parasite. Intensity of STH measurements was done through direct egg-count per gram using Kato Katz methods. Data analysis was done using SPSS version 25. Odds ratio with 95% confidence interval was used to measure association and p-value <0.05 was considered as statistically significant.

RESULTS

The study population (N = 264) consisted of 139(52.65%) male and 125 (47.34%) female with the mean ages of 36 ±16.12(±SD). The proportion of good compliance to hand hygiene during COVID-19 to was 43.93% (95%CI: 37% to 47) and prevalence of intestinal parasite was 26.14% (95%CI:21.2% to 31.75) comprising 23.48% intestinal protozoa and 6.43% of soil transmitted helminthic infection. Gardia lamblia, Entamoeba histolytica/dispar, Ascaris lumbricoides were the common parasite in the study area with prevalence of 15.53%, 6.44%, and 1.52% respectively. Prevalence of intestinal parasite among participants with good compliance to hand hygiene group and poor compliance to hand hygiene were (14.65% vs. 35.13%)(AOR: 0.48,95%CI:0.13 to 0.68) (p = 0.002) implying that good compliance to hand hygiene can reduce the risk of IPIs by 52%. Moreover significantly lower odds of intestinal protozoa among good compliance to hand hygiene group than the control (OR:0.38; (95%CI: 0.20 to 0.71);P = 0.001. However, no significant difference in the odds of intensity of STH infection in good compliance hand hygiene and poor compliance group. The result of this study also confirmed the association between intestinal parasitic infections and younger /adolescent age, education status, habit of eating raw vegetable and figure nail status.

CONCLUSION

Good hand hygiene compliance during COVID-19 significantly associated with reduction of intestinal parasitic infection. This finding highlights the secondary protective effect of improved hand hygiene against IPIs and suggest it can used in augmenting the existing parasitic control strategies in the study setting.

Direct hand hygiene observations and feedback increased hand hygiene compliance among nurses and doctors in medical and surgical wards - an eight-year observational study

BACKGROUND

The improvement of hand hygiene compliance (HHC) is critical to preventing healthcare-associated infections (HCAIs). The present study explored how direct observation and feedback influences HHC among nurses and doctors in surgical and medical wards, and whether these actions impact HCAI incidence.

METHODS

In this longitudinal observational study, HHC and the incidence of HCAIs were observed in six medical and seven surgical wards in a tertiary hospital in Finland from May 2013 to Dec 2020. Data of the observations of five hand hygiene (HH) moments were collected from the hospital HH and the HCAI monitoring registries. For statistical analyses a multivariable logistic regression analysis and a Poisson regression model were used.

FINDINGS

HH monitoring included 24 614 observations among nurses and 6 396 observations among doctors. In medical wards, HHC rates increased 10.8% - from 86.2% to 95.5%, and HCAI incidence decreased from 15.9 to 13.5 per 1000 patient days (p<0.0001). In surgical wards, HHC increased 32.7% - from 67.6% to 89.7%, and HCAI incidence decreased from 13.7 to 12.0 per 1000 patient days (p< 0.0001). The overall HHC increased significantly among nurses (17.8%) and doctors (65.8%). The HHC was better among nurses than doctors (in medical wards; OR 3.36; 95% CI 2.90-3.90, p<0.001 and in surgical wards; OR 9.85; 95% CI 8.97-10.8, p<0.001).

CONCLUSION

Direct observations and feedback of HH increased significantly HHC among nurses and doctors over an eight-year period. During the same period, the incidence of HCAIs significantly decreased in both medical and surgical wards.

Improving hand hygiene in a medical ward: a multifaceted approach

Background

Hand hygiene is a fundamental action which is simple, inexpensive and an effective tool in reducing hospital-acquired infections, yet compliance remains low in healthcare settings. In 2014, Changi General Hospital embarked on a pilot project to improve hand hygiene compliance in a pilot ward with the intention to eventually spread a multifaceted set of interventions hospital wide.

Methods

A before and after interventional study of a pilot project. Hand hygiene data collection was through direct observations by auditors using WHO monitoring standards and techniques based on the five-moment model.

Setting

A medical ward in an acute hospital in Singapore.

Results

Overall hand hygiene compliance improved from a median of 53% in 2015 to 80% by end of 2017. Hand hygiene compliance of doctors increased from 43% to 60% (p=0.00), nurses from 62% to 89% (p=0.014) and allied health staff from 67% to 83% (p=0.002).

Conclusions

A multifaceted set of interventions developed by the project team was effective in improving hand hygiene compliance of doctors, nurses and allied health staff.

Management Actions for Prevention and Control of Healthcare-associated Infections: A Grounded Theory approach

AIM

To understand the management actions for prevention and control of healthcare-associated infections performed by health professionals.

BACKGROUND

Prevention of nosocomial infections has evidence-based practice at its essence, but not all institutions are successful in implementing prevention methodology.

METHODS

Qualitative research with Grounded Theory methodological framework. The research was carried out in two southern Brazilian hospitals. Data collected was employed through open interviews with twenty-one health professionals and managers. This process occurred concurrently with the data analysis, through constant comparative analysis.

RESULTS

The understanding of the co-responsibility of managerial actions emerged as a central phenomenon of the theoretical model. Management actions for the prevention and control of healthcare-associated infections are a collective phenomenon, in which co-responsibility sustains the effectiveness of the offered assistance. The behaviors of health teams in the face of structural and human weaknesses influence the construction of a supportive relationship in the effectiveness of patient safety actions.

CONCLUSIONS

The sharing of responsibilities between professionals, and the actions of prevention and control of healthcare-associated infections arising from this conduct, positively influence the promotion of safer and improved quality care.

IMPLICATIONS FOR NURSING MANAGEMENT

Nursing managers should consider applying the tools to prevent and control HAIs and generate in-depth discussion to promote institution's cultural changes.
