Effects of a 4-year intervention on hand hygiene compliance and incidence of healthcare associated infections: a longitudinal study

Acceptability and tolerability of alcohol-based hand rubs among health workers and concessionaires in Malaysia during the COVID pandemic: a hospital-wide cross-sectional study using a modified WHO protocol

This study evaluated the acceptability and tolerability of three alcohol-based hand rubs (ABHRs) at Sarawak General Hospital, Malaysia. Conducted from 12-26 November 2021 using a modified WHO Protocol, it involved a survey among health workers and concessionaires, with a 35% response rate (1,598 of 4,628 participants). The majority were nurses (60.8%), with the medical division most represented (28.4%). Most respondents (93.2%) used ABHRs at least five days a week and found them easily accessible (72.3%). Product B was the preferred ABHR (65%), primarily for its color and fragrance, surpassing WHO's 50% approval rate in these aspects. However, no other product features met WHO criteria. There were no significant differences in self-reported skin tolerability across the products, and none achieved overall WHO approval. These results offer important insights for ABHR selection in developing countries and highlight the value of the WHO Protocol in assessing product acceptability and tolerability.

Decreased hospital-acquired respiratory infections among older inpatients during the COVID-19 pandemic: a retrospective observational study in a general hospital in China

BACKGROUND

To mitigate hospital-acquired transmission of coronavirus disease 2019 (COVID-19), various prevention and control measures have been strictly implemented in medical institutions. These stringent measures can potentially reduce the incidence of hospital-acquired respiratory infections. This study aimed to assess if there were changes in the prevalence of hospital-acquired respiratory infections during a period of national attention focused on COVID-19 prevention.

METHODS

A retrospective analysis of the clinical data from adult patients with hospital-acquired respiratory infections admitted between October and December 2019 and during the same period in 2020 was performed. All patients were referred from a general hospital in Beijing China and COVID-19 patients were not treated at the hospital. Hospital-acquired respiratory infections were diagnosed based on the criteria of the Centers for Disease Control and Prevention/National Healthcare Safety Network (CDC/NHSN). A comparison of the incidence and mortality rate of hospital-acquired respiratory infections between the two selected time periods was conducted. Additionally, multivariate logistics regression analysis was used to identify mortality-associated risk factors.

RESULTS

This study included 2,211 patients from October to December 2019 (pre-COVID-19 pandemic) and 2,921 patients from October to December 2020 (during the COVID-19 pandemic). The incidence of hospital-acquired respiratory infections in 2019 and 2020 was 4.7% and 2.9%, respectively, with odds ratio (OR): 0.61, 95% confidence interval (CI): 0.46-0.81, and P = 0.001. In-hospital mortality of hospital-acquired respiratory infections in 2019 and 2020 was 30.5% and 38.4%, respectively, with OR: 1.42, 95%CI: 0.78-2.59, and P = 0.25. Multivariate logistics regression analysis revealed that a history of previous malignancy (OR: 2.50, 95%CI: 1.16-5.35, P = 0.02), was associated with in-hospital mortality.

CONCLUSIONS

The incidence of hospital-acquired respiratory infections was significantly decreased following the implementation of various prevention and control measures during the COVID-19 pandemic. A history of previous malignancy was associated with higher in-hospital mortality in older inpatients with hospital-acquired respiratory infections.

An intervention study investigating the effectiveness of contextualizing multimodal strategy on improving hand hygiene at a tertiary hospital in Nigeria

BACKGROUND

Hand hygiene (HH) is a proven low-cost means to curtail the problem of hospital-acquired infection (HAI). However, a low HH compliance rate of 17.1% was found among surgical health workers at Ahmadu Bello University Teaching Hospital (ABUTH) in Zaria, Nigeria.

METHODS

This was an intervention study conducted utilizing mixed methods to investigate the effectiveness of the World Health Organization (WHO) multimodal strategy to improve the HH compliance rate of doctors at ABUTH Zaria. The study was conducted between June and August 2022 and included delivering a behavioural change HH workshop to doctors followed by data collection in the surgical wards that had received environmental modification through the provision of an alcohol-based hand rub (ABHR), HH posters and nurses for visual and/or verbal reminders.

RESULTS

The cumulative HH compliance rate was 69% (n=1774) and was significantly different from the baseline HH compliance rate of 17.1% (confidence interval 45.5 to 57.7, p<0.001). Observed HH was highest in the ward with both visual and verbal reminders (78%) and lowest (59%) where neither visual nor verbal reminders were provided (n=444 per ward). All respondents reported motivation to perform HH with the presence of ABHR.

CONCLUSIONS

The WHO multimodal strategy is good for enhancing HH among health workers in the context of low- and middle-income countries. More research is needed to understand how much of a reduction in HAI is directly associated with efficient HH by health workers.

Current issues in hand hygiene

BACKGROUND

Multiple aspects of hand hygiene have changed in recent years.

METHODS

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

RESULTS

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

CONCLUSIONS

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

Clean hands, safe care: how knowledge, attitude, and practice impact hand hygiene among nurses in Najran, Saudi Arabia

Introduction

Healthcare-acquired infections are infections that patients acquire while receiving treatment for a medical or surgical condition and can occur in all care facilities. Hospital-acquired infections and the spread of antimicrobial resistance can be reduced by implementing proper preventive measures, including hand hygiene.

Aim

This study aimed to assess nurses' knowledge and attitudes toward hand hygiene guidelines in Najran city, determine compliance levels, identify factors contributing to non-compliance, and provide recommendations for interventions to improve hand hygiene practices and reduce healthcare-associated infections risk.

Subject and methods

This cross-sectional study was conducted among nurses working in the selected government hospitals in Najran City, Saudi Arabia. A self-administered questionnaire was distributed among the targeted nurses using an online survey. The questionnaire includes socio-demographic characteristics such as age, gender, and marital status. The questionnaire had 25 items to measure knowledge, 10 to measure attitude, 6 to measure practices, and 4 to measure the impact of COVID-19 on hand hygiene practices.

Results

Among the 386 nurses recruited, 88.3% were females, and 25.6% were aged between 31 to 35 years old. Overall, good knowledge, positive attitude, and good practice levels were found in 42.5, 48.4, and 94%, respectively. The common factor influencing hand hygiene practice was the prevention of cross-infection (88.1%). The total knowledge score mean was 18 ± 3.4 (highest possible score: 25). The total attitude score mean was 37.5 ± 6.1 (highest possible score: 50). The total practice score mean was 26.9 ± 2.8 (highest possible score: 30). A higher score indicates higher KAP of hand hygiene. Factors associated with increased KAP were being older in age (Z = 6.446; p < 0.001), gender female (Z = 9.869; p < 0.001), being a Filipino nurse (H = 117.8; p < 0.001), working in a surgery department (H = 28.37; p < 0.001), having more than 10 years of experience (Z = 6.903; p < 0.001), living in shared accommodation (H = 87.22; p < 0.001), having associated chronic disease (Z = 4.495; p < 0.001), and receiving formal training in hand hygiene (Z = 2.381; p = 0.017). There was a positive highly statistically significant correlation between knowledge score and attitude score (r = 0.556), between knowledge score and practices score (r = 0.303), and between attitude score and practices score (r = 0.481).

Conclusion

In light of the results, we can say that the nurses' knowledge, attitude, and practice in regards to hand hygiene were deemed acceptable. We noticed that female nurses who were older and had more experience, as well as those who had received formal hand hygiene training, displayed better KAP compared to their counterparts. Moreover, we found a significant and positive correlation between the scores for knowledge, attitude, and practice. Nonetheless, additional research is necessary to establish the extent of KAP concerning hand hygiene.

Core components of infection prevention and control programs at the facility level in Kazakhstan: key challenges and opportunities

BACKGROUND

Kazakhstan is developing a National Roadmap to strengthen its Infection Prevention and Control (IPC), but until recently has lacked a country-wide facility-level assessment of IPC performance gaps.

METHODS

In 2021, the World Health Organization (WHO)'s IPC Core Components and Minimal Requirements were assessed at 78 randomly selected hospitals across 17 administrative regions using adapted WHO tools. The study included site assessments, followed by structured interviews with 320 hospital staff, validation observations of IPC practices, and document reviews.

RESULTS

All hospitals had at least one dedicated IPC staff member, 76% had IPC staff with any formal IPC training; 95% established an IPC committee and 54% had an annual IPC workplan; 92% had any IPC guidelines; 55% conducted any IPC monitoring in the past 12 months and shared the results with facility staff, but only 9% used monitoring data for improvements; 93% had access to a microbiological laboratory for HAI surveillance, but HAI surveillance with standardized definitions and systematic data collection was conducted in only one hospital. Adequate bed spacing of at least 1 m in all wards was maintained in 35% of hospitals; soap and paper towels were available at the hand hygiene stations in 62% and 38% of hospitals, respectively.

CONCLUSIONS

Existing IPC programs, infrastructure, IPC staffing, workload and supplies present within hospitals in Kazakhstan allow for implementation of effective IPC. Development and dissemination of IPC guidelines based on the recommended WHO IPC core components, improved IPC training system, and implementation of systematic monitoring of IPC practices will be important first steps towards implementing targeted IPC improvement plans in facilities.

Barriers and Problems in Implementing Health-Associated Infections Surveillance Systems in Iran: A Qualitative Study

Background

Healthcare-associated infections (HAIs) are among the most critical challenges for patients and healthcare providers. To achieve the goals of the surveillance system, it is necessary to identify its barriers and problems. This study aimed to identify the barriers and problems of the surveillance system for HAIs.

Methods

This qualitative study was conducted using the content analysis method to investigate the challenges of this surveillance system from the perspective of 18 infection control nurses from hospitals in different cities of Iran with work experience of 1 to 15 years. Data were collected through semi-structured interviews and analyzed using the Lundman and Graneheim qualitative content analysis method.

Results

In this study, we found 2 categories and 7 subcategories. Two categories were barriers related to human resources and organizational barriers to infection control. The 7 subcategories included weakness of medical staff in adherence to health principles, obstacles related to patients, high workload and insufficient motivation, lack of staff knowledge, lack of human resources, functional and logistical weaknesses, and weaknesses in the surveillance system.

Conclusion

To reduce problems and improve HAIs reporting, the HAIs surveillance system needs the support of health system officials and managers. This administrative and support focus can establish the framework for removing and lowering other barriers, such as the number of reported cases, physician and staff noncooperation, and the prevalence of HAIs. It can also bring HAIs cases closer to reality.

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.

Evaluation of the Residual Disinfection Effects of Commonly Used Skin Disinfectants against Viruses: An Innovative Contact Transmission Control Method

Lasting disinfection effects, that is, the residual disinfection effects (RDEs), of skin-coated disinfectants have rarely been considered for infection control owing to the challenges involved in the accurate evaluation of RDEs. In this study, we constructed a new skin evaluation model and determined the RDEs of existing disinfectants against viruses. Our results showed that ethanol and isopropanol had no RDE, whereas povidone-iodine, chlorhexidine gluconate, and benzalkonium chloride (BAC) exhibited RDEs, with 10% povidone-iodine and 0.2% BAC showing particularly strong RDEs. The RDE of 0.2% BAC was strong enough to reduce the median survival times of severe acute respiratory syndrome coronavirus-2, human coronavirus-OC43, and influenza virus from 670 to 5.2, 1300 to 12, and 120 to 4.2 min, respectively. Additionally, this strong RDE was maintained even 4 h after coating the skin. Clinical data also showed that the strong RDE of 0.2% BAC was maintained for more than 2 h. Thus, applying disinfectants with strong RDEs on the skin correlates with a reduction in virus survival time and appears to create a skin surface environment that is not conducive to virus survival. A prolonged reduction in virus survival decreases the contact transmission risk, thereby enabling stronger infection control.

Mixed methods study evaluating the implementation of the WHO hand hygiene strategy focusing on alcohol based handrub and training among health care workers in Faranah, Guinea

Introduction

The most frequent adverse health events in healthcare worldwide are healthcare-associated infection. Despite ongoing implementation of the WHO multimodal Hand Hygiene (HH) Improvement Strategy, healthcare-associated infection rate continues to be twofold higher in low- than in high-income countries. This study focused on continued evaluation of HH compliance and knowledge. The mixed method approach, with inclusion of patients and care-givers, provided insight into challenges and facilitators of the WHO HH Improvement Strategy, and highlighted improvement points.

Methods

An uncontrolled, before-and–after intervention, mixed methods study in Faranah Regional Hospital was conducted from December 2017 to August 2019. The intervention implemented the WHO HH Strategy including HH training for healthcare workers (HCWs), and the relaunch of the local production of alcohol-based handrub (ABHR). A baseline assessment of HH knowledge, perception and compliance of HCWs was done prior to the intervention and compared to two follow-up assessments. The second follow-up assessment was complemented by a qualitative component.

Results

Overall compliance six months post-intervention was 45.1% and significantly higher than baseline but significantly lower than in first follow-up. Knowledge showed similar patterns of improvement and waning. The perception survey demonstrated high appreciation of the intervention, such as local production of ABHR. HCW’s were concerned about overconsuming of ABHR, however simultaneous quantitative measurements showed that consumption in fact was 36% of the estimated amount needed for sufficient HH compliance. Potential fields for improvement identified by HCWs to enhance sustainability were permanent ABHR availability, having a dedicated person with ownership over continuous simulation HH trainings including simulations to improve technique.

Conclusion

The study shows that the WHO multimodal HH strategy has a positive effect on HCW compliance and knowledge. Improvement points identified by local staff like sensitization on appropriate ABHR amount per HH action should be considered for sustainable HH improvement.
