Barriers to hand hygiene compliance in intensive care units during the COVID-19 pandemic: A qualitative study

Italian National Surveillance of Alcohol-Based Hand Rub Consumption in a Healthcare Setting-A Three-Year Analysis: 2020-2022

Background/Objectives: Hand hygiene (HH) is pivotal in mitigating infectious disease transmission and enhancing public health outcomes. This study focuses on detailing the national surveillance system for alcohol-based hand rub (ABHR) consumption in healthcare facilities across Italy, presenting results from a comprehensive three-year evaluation period, from 2020 to 2022. It aims to delineate this surveillance system and report on ABHR consumption trends in various Regions/Autonomous Provinces (Rs/APs). Methods: ABHR consumption data, collected through the ABHR Italian national surveillance system, coordinated by the Istituto Superiore di Sanità (ISS), were analyzed. Statistical methods, e.g., the Mann-Whitney test, were used to assess trends in ABHR consumption, expressed in liters per 1000 patient days (L/1000PD). Results: The results show significant variation in ABHR consumption across Rs/APs and over the years studied. National median ABHR consumption decreased from 2020 to 2022, with a significant reduction from a median of 24.5 L/1000PD in 2020 to 20.4 L/1000PD in 2021 and 15.6 L/1000PD in 2022. Conclusions: The decline in ABHR consumption raises concerns about the ongoing adherence to HH practices in Italian healthcare settings. This underscores the essential role that systematic ABHR monitoring and improved surveillance play in enhancing HH compliance, suggesting that sustained and strategic efforts are fundamental to uphold high standards of hygiene and to effectively respond to fluctuating ABHR usage trends over time. Further research is needed to explore barriers to effective ABHR use and to develop targeted strategies to improve HH practices.

Antimicrobial resistance patterns among critical priority pathogens in an intensive care unit at a tertiary hospital in Egypt: a descriptive analysis comparing pre- and COVID-19 eras

Background. The intensified global challenge of antimicrobial resistance, set against the backdrop of the COVID-19 pandemic, is a cause for major concern. Within healthcare settings, intensive care units are recognized as focal points for Gram-negative infections. The study pursued to assess the prevalence and antimicrobial resistance patterns of critical priority pathogens (Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacteriaceae, comprising Klebsiella pneumoniae and Escherichia coli) during both pre- and COVID-19 periods.Gap Statement. The decision to explore this topic stemmed from the urgent need to understand how the exceptional healthcare crisis of COVID-19 affected AMR patterns.Methods. This was an observational retrospective analysis of 1056 clinical specimens obtained from 950 patients who were admitted to the Medical Intensive Care Unit at Kasr Al-Aini Hospital, Cairo University, Egypt.Results. In the period before COVID-19, 342 pathogenic isolates (135 K. pneumoniae, 83 P. aeruginosa, 76 A. baumannii and 48 E. coli) were obtained from samples collected from 450 patients. Conversely, during the COVID-19 period, 714 isolates (237 K. pneumoniae, 205 A. baumannii, 199 P. aeruginosa and 73 E. coli) were collected from the same number of patients. In the course of the pandemic, there is a slight increase in A. baumannii and P. aeruginosa infections, whereas E. coli and K. pneumoniae exhibit a distinct trend with a noticeable reduction in infection rates during COVID-19. During the COVID-19 period, a noticeable rise in resistance rates was observed for all antibiotics utilized. The results from Fisher's exact test indicated a substantial increase in resistance towards certain antibiotics. Specifically, a significant rise in resistance was observed for E. coli to ciprofloxacin (P = 0.00), gentamicin and P. aeruginosa (P = 0.02), levofloxacin and A. baumannii (P = 0.01), piperacillin-tazobactam and A. baumannii (P = 0.04), and piperacillin-tazobactam and P. aeruginosa (P = 0.01).Conclusion. Our results display how the pandemic impacted bacterial infections and antibiotic resistance, indicating a general increase in resistance rates. These findings are crucial for guiding healthcare practices, emphasizing the need for continued surveillance and potentially checking antibiotic usage schemes.

Hand contamination and hand hygiene knowledge and practices among commercial transport users after the SARS-CoV-2 virus (COVID-19) scare, Enugu State, Nigeria

Contaminated hands are one of the most common modes of microorganism transmission that are responsible for many associated infections in healthcare, food industries, and public places such as transportation parks. Public health approaches during COVID-19 pandemic have shown that hand hygiene practices and associated knowledge are critical measure to control the spread of infectious agent. Hence, assessment of commercial transport users' knowledge, belief and practices on hand hygiene, and potential contamination with infectious agents which is the aim of the study, aligns with general health concern of quantifying contamination risk levels to predict disease outbreaks. This study utilized a randomized sampling approach to select 10 frequently used commercial parks within two districts in the State: Enugu and Nsukka. The parameters analysed include a cross-sectional questionnaire survey, hand swab and hand washed samples collected from dominant hand of participants. A total of 600 participants responded to the questionnaire survey, while 100 participants' hand swabs were examined for microbial contamination. This study recorded a high prevalence of fungal (90.0%) and bacterial (87.0%) species; 20 species of fungus were identified with prevalence range of 1% to 14%; 21 bacterial species were isolated with prevalence range of 1% to 16%. These species were identified as either opportunistic, non-invasive, or pathogenic, which may constitute a health concern amongst immunocompromised individuals within the population. Aspergillus spp. (14%), was the most common fungal species that was exclusively found amongst Nsukka commercial users, while E. coli was the most prevalent isolated bacterial species amongst Nsukka (12%) and Enugu (20%) commercial park users. Prevalence of fungal contamination in Nsukka (94.0%; 47/50) and Enugu (86.0%; 43/50) were both high. Prevalence of bacterial contamination was higher in Enugu than Nsukka but not significantly (47[94.0%] vs. 40[80.0%], p = 0.583). A greater number of participants (99.3%) were aware of the importance of hand hygiene, however with low compliance rate aside "after using the toilet" (80%) and "before eating" (90%), other relevant hand washing and sanitizing practices were considered less important. With these observations, we can emphatically say that despite the COVID-19 scare, commercial park users within the sampled population do not efficiently practice quality hand wash and hygiene measures, hence, risking the widespread of infectious agents in situation of disease outbreak or among immunocompromised individuals.

Enablers and barriers to vaccine uptake and handwashing practices to prevent and control COVID-19 in Kenya, Uganda, and Tanzania: a systematic review

The global emergence of coronavirus disease 2019 (COVID-19) posed unprecedented challenges, jeopardizing decades of progress in healthcare systems, education, and poverty eradication. While proven interventions such as handwashing and mass vaccination offer effective means of curbing COVID-19 spread, their uptake remains low, potentially undermining future pandemic control efforts. This systematic review synthesized available evidence of the factors influencing vaccine uptake and handwashing practices in Kenya, Uganda, and Tanzania in the context of COVID-19 prevention and control. We conducted an extensive literature search across PubMed, Science Direct, and Google Scholar databases following Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Out of 391 reviewed articles, 18 were eligible for inclusion. Some of the common barriers to handwashing in Kenya, Uganda, and Tanzania included lack of trust in the government's recommendations or messaging on the benefits of hand hygiene and lack of access to water, while some of the barriers to vaccine uptake included vaccine safety and efficacy concerns and inadequate awareness of vaccination sites and vaccine types. Enablers of handwashing practices encompassed hand hygiene programs and access to soap and water while those of COVID-19 vaccine uptake included improved access to vaccine knowledge and, socio-economic factors like a higher level of education. This review underscores the pivotal role of addressing these barriers while capitalizing on enablers to promote vaccination and handwashing practices. Stakeholders should employ awareness campaigns and community engagement, ensure vaccine and hygiene resources' accessibility, and leverage socio-economic incentives for effective COVID-19 prevention and control.

Toxicity of chemical-based hand sanitizers on children and the development of natural alternatives: a computational approach

The unintended exposure of children to hand sanitizers poses a high risk of potentially fatal complications. Skin irritation, dryness, cracking, peeling, hypoglycemia, apnea, and acidosis are examples of unintended consequences of hand sanitizer. The sanitizer reportedly kills normal microbial flora on hands, which usually promotes innate immunity among children under 12. Children are more susceptible to the toxicity associated with the chemical constituents of marketed chemical-based hand sanitizers; however, the studies to develop sanitizer formulations for children are rudimentary. The adverse events limit the use of hand sanitizers specifically in children because of their sensitive and delicate skin. Additionally, it is reported that many chemical-based hand sanitizer formulations, especially alcohol-based ones may also contain contaminants like methanol, acetaldehyde, benzene, isopropanol, and ethyl-acetate. These contaminants are found to be hazardous to human health exhibiting toxicity on ingestion, inhalation, or dermal exposure, especially in children. Therefore, it is important to design novel, innovative, safer sanitizer formulations for children. The study aims to discuss the toxic contaminants in chemical-based sanitizer formulations and propose a design for novel herbal formulations with minimal toxicity and adverse effects, especially for children. The review focuses on ADMET analysis of the common contaminants in hand sanitizers, molecular docking, Lipinski's rule of five analysis, and molecular simulation studies to analyze the efficacy of interaction with the receptor leading to anti-microbial activity and drug-likeness of the compound. The in silico methods can effectively validate the potential efficacy of novel formulations of hand sanitizers designed for children as an efficient alternative to chemical-based sanitizers with greater efficacy and the absence of toxic contaminants.

Health Science Students' Perceptions of Hand Hygiene Education and Practice in a South African University: Introducing the University Hand Hygiene Improvement Model

Hand hygiene serves as a critical preventative measure against the spread of acquired infections in healthcare facilities and is an integral component of patient safety programs. While healthcare students in training are typically introduced to the principles underlying hand hygiene, the translation of this understanding into practice is often lacking, and compliance has remained low. This study aimed to evaluate health science students' in biomedical sciences, chiropractic and emergency medical care, environmental health, complementary medicine, medical imaging and radiation sciences, nursing, optometry, podiatry, and sports and movement studies perceptions regarding hand hygiene education (knowledge and attitude) and practice at a university in South Africa. Consenting students were asked to complete an online questionnaire that tested their knowledge, practices, and skills in handwashing. The ANOVA analysis results suggested significant differences in hand hygiene scores across departments and years of study. The multiple regression analyses confirmed these findings, suggesting that the department of study significantly influenced all aspects of hand hygiene, while the year of study affected hand hygiene skills, and age group influenced hand hygiene practices. Based on these findings, a conceptual model, the University Hand Hygiene Improvement Model (UHHIM), was proposed to enhance the teaching and learning of hand hygiene at the university level. The model underscores the necessity of targeted education, continuous monitoring, and feedback, and the pivotal roles of hand hygiene facilitators and student participation in enhancing hand hygiene behaviors.

Hand hygiene knowledge, attitude, barriers and improvement measures among healthcare workers in the Republic of Korea: a cross-sectional survey exploring interprofessional differences

BACKGROUND

Hand hygiene (HH) is a fundamental component of infection prevention and control in healthcare settings. This study aimed to identify knowledge, attitude, and barriers to HH according to occupational groups and strategies to increase the rate of HH compliance among healthcare workers (HCWs).

METHODS

This cross-sectional survey was conducted in July 2018 at four university-affiliated hospitals. The survey comprised seven parts with 49 items, including self-reported HH compliance, knowledge, attitudes, behaviours, barriers to HH, and improvement strategies.

RESULTS

A total of 1046 HCWs participated in the survey. The nursing group's self-reported HH compliance rate was the highest, followed by other HCWs and physicians. The scores regarding knowledge, attitudes, and behaviours regarding HH were the highest in the nursing group. The nursing group also had higher internal and emotional motivation scores. Physicians and nurses found HH the most challenging in emergencies, while other HCWs considered skin problems caused by HH products the most significant barrier. Among 12 improvement measures, approximately 20% of the respondents ranked "diversify types of hand sanitisers," "install soap and paper towels in each hospital room," and "change perception through various HH campaigns" as the top three priorities. The physician group deemed the timely reminder of HH compliance as the second most critical improvement measure.

CONCLUSION

Differences in knowledge, attitude and barriers hindering HH compliance and improvement plans were identified for each group. The findings suggest that targeted interventions tailored to the specific needs of different occupational groups may effectively improve HH compliance in healthcare settings.

The Assessment of Nursing Staff Knowledge and Barriers Regarding Aseptic Techniques in Khartoum Teaching Hospital, Sudan

Background Aseptic techniques are crucial in preventing healthcare-associated infections, which are an integral part of standard precautions, and encompass a range of practices designed to safeguard patients from healthcare-associated infections. Objective The objective of this study was to evaluate the level of knowledge and identify the barriers faced by nursing staff in implementing aseptic techniques. Methodology This study employed a stratified random sampling technique to ensure the representation of the research sample. A cross-sectional, descriptive research design was used to assess the knowledge and barriers of nursing staff in maintaining aseptic techniques in their medical practice at Khartoum Teaching Hospital, Sudan. The nursing staff members were divided into different units, and a proportionate number of participants were randomly selected from each stratum. A total of 83 nursing staff members were recruited for this study. Data collection was conducted using a structured questionnaire specifically designed for this study. The questionnaire consisted of items that assessed the nursing staff's knowledge and barriers to aseptic technique implementation. Results The study findings revealed that the mean knowledge score of nursing staff was 14.12, with a median score of 15. The knowledge score had a standard deviation of 3.22. Approximately two-thirds of the nurses (66.3%) had an average level of knowledge, while 33.7% had a below-average level of knowledge. The chi-square analysis indicated a significant association between educational level, years of experience, and knowledge scores (P value=0.010) at a significance level of 0.05. Additionally, 65% of the participants reported facing multiple challenges in maintaining aseptic techniques, including insufficient training, limited resources, and inadequate support. Conclusion In conclusion, the evaluation revealed that a significant proportion of participants felt that their unit lacked adequate training and resources for aseptic techniques. Many had observed colleagues not adhering to aseptic practices, and the participants faced multiple challenges in maintaining aseptic techniques, including insufficient training, limited resources, time constraints, and inadequate support.

How can lessons from the COVID-19 pandemic enhance antimicrobial resistance surveillance and stewardship?

COVID-19 demanded urgent and immediate global attention, during which other public health crises such as antimicrobial resistance (AMR) increased silently, undermining patient safety and the life-saving ability of several antimicrobials. In 2019, WHO declared AMR a top ten global public health threat facing humanity, with misuse and overuse of antimicrobials as the main drivers in the development of antimicrobial-resistant pathogens. AMR is steadily on the rise, especially in low-income and middle-income countries across south Asia, South America, and Africa. Extraordinary circumstances often demand an extraordinary response as did the COVID-19 pandemic, underscoring the fragility of health systems across the world and forcing governments and global agencies to think creatively. The key strategies that helped to contain the increasing SARS-CoV-2 infections included a focus on centralised governance with localised implementation, evidence-based risk communication and community engagement, use of technological methods for tracking and accountability, extensive expansion of access to diagnostics, and a global adult vaccination programme. The extensive and indiscriminate use of antimicrobials to treat patients, particularly in the early phase of the pandemic, have adversely affected AMR stewardship practices. However, there were important lessons learnt during the pandemic, which can be leveraged to strengthen surveillance and stewardship, and revitalise efforts to address the AMR crisis.
