Background: Hand hygiene is one of the most important hygiene measures to prevent healthcare-associated infections. Well-functioning hand rub dispensers are the foundation of hand hygiene but are often overlooked in research. As the point of origin for hand hygiene, dispensers not only promote compliance through ease of use, but also strongly influence the amount of hand rub used per disinfection. This work investigates how dispenser types and conditions affect dispensed volumes and usability. Methods: Data from 5,014 wall-mounted or point-of-care dispensers was collected from 19 German healthcare facilities during installation of an electronic hand hygiene monitoring system, including dispenser type and dispensed hand rub volumes. Of these dispensers, 56.2% were metal dispensers, and the majority (89.5%) were wall-mounted. For one hospital, 946 wall-mounted dispensers were analyzed in detail regarding pump material, damages, functionality, cleanliness, and filling levels. Results: Dispensed volumes varied across and within dispenser types, ranging from 0.4 mL to 4.4 mL per full actuation, with the largest volumes generally dispensed by plastic dispensers with a preset of 1.0 to 3.0 mL per actuation. In general, most dispensers dispense more hand rub per full actuation than specified by the manufacturer. When different types of dispensers are used within a healthcare facility, vastly different volumes can be dispensed, making reliable and reproducible disinfection difficult for healthcare workers. In the detailed analysis of 946 dispensers, 27.1% had cosmetic defects, reduced performance, or were unusable, with empty disinfectant being the most common reason. Only 19.7% of working dispensers delivered their maximum volume on the first full actuation. Conclusion: Even though several studies addressed the variability in dispensed volumes of hand hygiene dispensers, studies dealing with dispenser types and functionality are lacking, promoting the common but false assumption that different dispensers may be equivalent and interchangeable. Variability in dispensed volumes, coupled with frequent dispenser defects and maintenance issues, can be a major barrier to hand hygiene compliance. To support healthcare workers, more attention should be paid to 'dispenser compliance', selecting dispensers with similar volume ranges and proper maintenance. [ABSTRACT FROM AUTHOR]

Aim: Atmospheric pressure cold plasma is the fourth state of matter obtained at low temperature with atmospheric pressure, which has antimicrobial, anti-inflammatory, sterilization, disinfection and surface modification enhancing properties. The aim of this study is to investigate the effectiveness of plasma activated medium (PAM) obtained from atmospheric pressure cold plasma on hand disinfection. Methods and Materials: The study was carried out on 15 individuals aged between 18 and 65 with healthy hand structures (no wounds, no pathology). Of the 15 individuals, 5 were selected as cleaning staff, 5 as office stuff, and 5 as academics. Samples were first taken from individuals using swap for bacterial identification. Afterwards, they were asked to wash their hands for 5 minutes in 250 ml PAM. At the end of the period, samples were taken from the individuals in the same way for bacterial identification using swap. The effectiveness of PAM in terms of hand disinfection was determined by comparing these two samples. Results: As a result of our study, it was found that bacterial colonies decreased in 3 of the samples taken from the hands of 5 cleaning personnel, remained stable in 2, a decrease in bacterial colonies in 4 of 5 office stuff, remained constant in 1, a decrease in bacterial colonies in 3 of 5 academicians, and remained stable in 2 of them. Staphylococcus aureus, Staphylococcus epidermidis, Bacillus megaterium, Staphylococcus capitis, Streptococcus mitis, Staphylococcus warneri bacteria were identified on the hands of individuals. Conclusion: As a result of our study, it was found that PAM, which has no side effects in the literature, can be an effective tool for hand disinfection.

Introduction: Transient microbial flora on the hands of medical personnel is a prerequisite for healthcare-associated infections. Unlike permanent this micro flora can be removed by washing and disinfection. The hands of the dental staff are factor number one in the transfer of microorganisms: from patient to patient as well as on objects from the dental environment. The aim of the present study was to microbiologically examine hand washes of 5th year dental students and medical staff before starting work with a patient in order to evaluate the quality of hygienic disinfection performed. Methodology: The hands of a total of 115 doctors and students from the Faculty of Dental Medicine of the Medical University of Plovdiv were wiped with a sterile swab after treatment with a disinfectant. Isolates were identified to species using Vitek MS and MALDI-TOF technology. Results: Coagulase-negative staphylococci with a microbial number of 103-104 were found to have the highest microbial count (70%). 9% of the samples with coagulase-negative staphylococci had microbial count ≥105. The most common isolates detected were: Staphylococcus hominis, Staphylococcus epidermidis and Micrococcus luteus. Conclusion: The presence of coagulase-negative staphylococci in a high microbial count, enterococci and representatives of Bacillus simplex is undesirable, especially in immunosuppressed patients. These results highlight the need to increase knowledge about hand disinfection and its actual application before working with a patient.

Abstract Background Undergraduate training in hand hygiene is a keystone of infection control. Several studies have shown overconfidence effects in hand hygiene practices, which can impair metacognition. We hypothesized that overconfidence might be prevalent in the early education stages of nursing students and that these effects could be reduced through frequent interactive learning formats, such as learning groups. Methods We conducted a multicenter cross-sectional questionnaire with 196 German nursing students, including general, surgical, and anesthetic nursing specializations. Results Overconfidence was observed in nursing students across all specialties and years of education. The cluster analyses showed three different types of learners: two characterized by overconfidence and one demonstrating justifiable confidence. Furthermore, the moderation analysis indicated that providing feedback and promoting metacognition regarding students’ learning achievements could mitigate overplacement, particularly through the frequent implementation of interactive teaching formats. Discussion Despite some limitations, these findings highlight the prevalence of overconfidence effects in nursing students, the presence of different learning profiles, and the importance of incorporating feedback within interactive learning formats concerning hand hygiene. Accordingly, educators need to be trained and supervised to deliver these learning formats and provide feedback to students effectively.

Objective: Unusual clinical course. Background: Ethanol intoxication is very common, and several forms of alcohol intoxication can lead to emergency department visits. Excessive alcohol users, when in withdrawal, might seek replacement alcoholic beverages; one of the common sources of ethanol is hand sanitizer, which contains 45-95% alcohol. It becomes even more challenging to deal with alcohol use disorder patients when they seek these replacement products inside hospital premises, and medical clinics and hospitals have increased their use of ethanol-based hand sanitizer since the start of the COVID-19 pandemic. Case Report: We report the case of a 26-year-old man with alcohol dependence presenting with a fictitious illness leading to hospital admission and consumption of ethanol-based hand sanitizer in the emergency department (ED). The patient initially presented reporting severe abdominal pain that persisted despite medications. The initial laboratory tests and imaging were non-significant. The patient was later caught stealing hand sanitizer bottles, consuming them within 4-6 h. The COVID-19 pandemic has increased alcohol intoxication, especially in EDs. Hand sanitizers, including ethanol, are toxic and hazardous when misused, mostly by adolescents and young adults. Treatments include glucose determination, dextrose infusion, and thiamine perfusion. Strategies to reduce ethanol intoxication include eliminating hand sanitizers, using wall-fixed sanitizers, and using sanitizer wipes. Conclusions: Patients with alcohol use disorder are known to develop alcohol-seeking behaviors. This report has highlighted that healthcare professionals should be aware that the increased availability of ethanol-based hand sanitizers, some of which contain toxic antiviral chemical agents, may be targeted by individuals with alcohol dependency.

Healthcare-associated infections (HAIs) are considered to be one of the biggest health problems as they continue to be an important cause of morbidity and mortality worldwide. They cannot be completely prevented, but their incidence can be significantly limited. Preventive action is the most important measure in this case. Due to the frequent interaction between healthcare professionals and patients, the crucial importance of hand hygiene is therefore emphasised. Adherence to good disinfection and hand washing practices remains around 40%, which can be improved by using a variety of nudge tools to promote desired hygienic behaviour. We conducted an open observation of employees and visitors with participation. The aim of this study was to determine the actual status of hand disinfection in a selected healthcare facility amongst doctors, registered nurses, medical technicians, cleaners, and visitors or parents of children; then, we selected and introduced three nudge tools of desired hygiene behaviour and analysed their effectiveness; finally, we provided suggestions for the use of nudge tools of desired hygiene behaviour with the aim of influencing doctors, registered nurses, medical technicians, cleaners, and visitors or parents of children so that they disinfect their hands properly. The actual state of hand disinfection was determined on the basis of observation without introducing any changes; then, we separately introduced three nudge tools, posters with an inscription and picture, the scent of citrus, and flashing lights. The obtained results were analysed with the help of the SpeedyAudit Lite application, and the effectiveness of each nudge tool and the adequacy of hand disinfection by categories of people were compared. In general, posters with a picture and an inscription contributed the most to more consistent disinfection of employees' hands, while the scent of citrus and flashing lights contributed slightly less.

The consensus-based guideline “hand antisepsis and hand hygiene” for Germany has the following sections: Prevention of nosocomial infections by hygienic hand antisepsis, prevention of surgical site infections by surgical hand antisepsis, infection prevention in the community by hand antisepsis in epidemic or pandemic situations, hand washing, selection of alcohol-based hand rubs and wash lotions, medical gloves and protective gloves, preconditions for hand hygiene, skin protection and skin care, quality assurance of the implementation of hand hygiene measures and legal aspects. The guideline was developed by the German Society for Hospital Hygiene in cooperation with 22 professional societies, 2 professional organizations, the German Care Council, the Federal Working Group for Self-Help of People with Disabilities and Chronic Illness and their Family Members, the General Accident Insurance Institution Austria and the German-speaking Interest Group of Infection Prevention Experts and Hospital Hygiene Consultants.

Aim: Hand hygiene is critical for the prevention of healthcare-associated infections, yet it is poorly practiced by healthcare workers. The aim of this study is to examine the effects of various incentives on the correctness of hand disinfection technique and motivation to use the technique correctly. Participants and Methods: The experiment was performed on three different days with 36 healthcare students. The procedure on the first and third day was the same and equal for all four groups (feedback alone). On the second day, the groups received different incentives (1: feedback + demonstration + creative teamwork; 2: feedback + demonstration + lecture; 3: feedback + demonstration; 4: feedback alone). Correctness (gel coverage percentage) and motivation were measured and compared between the three measurements. Results: Initially, only 25% of participants achieved at least 95% coverage, and only 55.56% tried at least “quite a bit” to use the technique correctly. Coverage increased after the incentive in groups 1 (χ(2)² = 6.000; P = 0.050), 2 (χ(2)² = 7.750; p = 0.021), and 3 (χ(2)² = 15.273; P = 0.001). Motivation increased in groups 1 (χ(2)² = 10.571; P = 0.005) and 3 (χ(2)² = 7.515; P = 0.023). Dorsum coverage was significantly smaller than palm coverage in both hands. Conclusion: Demonstration of hand disinfection technique, creative teamwork, and lecture were effective in adopting the habit of hand disinfection and reinforcing motivation to do so, but scanner feedback alone wasn’t effective in this way. Future studies should examine longer follow-up period and testing these results in clinical settings. [ABSTRACT FROM AUTHOR]

Background: Inadequate water, sanitation and hygiene (WASH) may lead to an increase in water-borne diseases like diarrhoea. The objective of the study was to assess water, sanitation and hygiene in the urban slums of Patpur, Bankura and to determine the implications of WASH on the occurrence of diarrhoea among under-five (U-5) children. Materials and Methods: A cross-sectional observational study was conducted during January--March 2020 by interviewing persons involved in water collection from each of the 182 slum households of Patpur, by two-stage sampling using a pre-designed structured schedule and the core questions on drinking WASH for household surveys: 2018 update by UNICEF and WHO. For testing the association between categorical variables, a Chi-square test was done. Binary logistic regression and the Hosmer Lemeshow test were done to know the predictors of diarrhoea in U-5 children. A P value of < 0.05 was considered statistically significant. Results: The proportion of diarrhoea among U-5 children was 0.34. Limited drinking WASH services were found in 3.30, 45.05 and 24.18% of households, respectively. Mobile objects users for handwashing were 14.05 times more prone to diarrhoea in U-5 children than those who had fixed handwashing facilities at their dwellings, yards or plots. Feeding children without handwashing had 5.70 times increased chances of diarrhoea among U-5 children than those who washed their hands before feeding. Conclusion: Handwashing facilities (fixed, mobile object or no facility) and handwashing with soap and water before feeding the child significantly affected the occurrence of diarrhoea among U-5 children.

Abstract Objective: to investigate factors associated with digital health literacy, hand hygiene knowledge and behavior among Brazilian adolescents during the COVID-19 pandemic. Method: cross-sectional study with 473 adolescents aged 15 to 19. Data were collected virtually between June and August 2021 through a questionnaire on sociodemographic characteristics, digital health literacy, knowledge and behavior regarding hand hygiene. Variables were adjusted using multiple linear regression models with normal response. Results: the average digital health literacy score was 29.89 ±5.30; for hand hygiene knowledge and behavior was 13.1 ±1.5 and 11.1±2.7, respectively. Higher knowledge and behavior scores for hand hygiene were associated with having completed high school, compared to those attending college, among those who attend health courses, seek information about the pandemic and in scientific articles. Higher digital health literacy scores in adolescents who did not wear masks when playing sports (p= 0.017). There was an association between digital health literacy and knowledge (p = 0.000) and behavior (p = 0.000) regarding hand hygiene. Conclusion: there is an association between higher digital health literacy scores and hand hygiene knowledge and behavior.

Context: Alcohol gel (70% ethanol, AG) and 2% chlorhexidine foam (CF) are hand antiseptics recommended by the World Health Organization. Although both are effective, it is unclear if one is superior to the other in a hospital setting. Aims: To evaluate the disinfectant ability comparing AG and CF by analyzing microbial reduction on the hands of nursing staff from two hospitals in Northern Peru. Methods: The nursing staff was randomly assigned to the AG and CF treatment groups. Before and after antisepsis, samples were taken by inserting the hands into a sterile self-closing bag containing peptone water. A sample of the liquid medium was plated on agar and used to calculate the CFU/mL of the peptone water. Participant data was analyzed in aggregate or according to hospital, profession, or service. Results: Both AG and CF were significantly effective in reducing CFU/mL. In aggregate, CFU/mL reduction was 80.9% for AG and 91.3% for CF, but the difference was not statistically significant. However, a small statistically significant difference in favor of CF was observed in the surgical center of both hospitals. These results are confirmed with multivariate analysis. Conclusions: AG and CF are both effective in hand antisepsis, but other factors are important when deciding which agent is appropriate for a specific healthcare setting.

We aimed to investigate the factors that impact the qualification rate of hand disinfection.Results: In this study, the qualification rate of hand disinfection was determined to be 64.38%. Notably, this rate exhibited significant variations based on gender, age, surgical site, and department category. Specifically, the qualification rate of hand disinfection among female participants stood at 82.35%, surpassing the qualification rate observed among male counterparts of 52.83%. Furthermore, doctors in the age group of 41– 50 years demonstrated the highest qualification rate, and the abdominal surgical site exhibited the most noteworthy qualification rate, reaching 79.49%. The outcomes of the multiple logistic regression analysis highlighted the significance of age and gender as influential factors impacting the qualification rate. Specifically, doctors aged 51 years or older exhibited the lowest hand hygiene compliance, whereas female doctors demonstrated a notably higher qualification rate compared to their male counterparts.Conclusion: The disheartening qualification rate of hand disinfection highlights a concerning lack of awareness regarding hand hygiene among surgeons in their professional duties. Consequently, targeted interventions are imperative, focusing on intensified training, educational initiatives, enhanced supervision, and internal performance evaluations for key groups. The findings not only serve as a valuable database but also offer a viable roadmap for similar hospitals to reinforce the management of nosocomial infections.Keywords: hand hygiene, hand disinfection, influencing factors, qualification rate, surgeons

BackgroundDuring the SARS-CoV-2 pandemic, nurses of primary health care has been an important role in Spain. Even so, the data obtained in the tracing have been scarcely used to investigate the possible mechanisms of transmission. Few studies focused on community transmission, evaluating the effectiveness of individual protective measures and exposure environment. The main aim of the study was to evaluate the association between individual protective measures and SARS-CoV-2 transmission in the community and to compare secondary attack rates in different exposure settings.MethodsA case–control study from contact tracing of SARS-CoV-2 index patients. COVID-19 contact tracing was led by nurses at the COVID-19 Coordinating Centre in Majorca (Spain). During the systematic tracing, additional information for this study was collected from the index patient (social-demographic variables, symptoms, the number of close contacts). And also, the following variables from their close contacts: contact place, ventilation characteristics mask-wearing, type of mask, duration of contact, shortest distance, case-contact relationship, household members, and handwashing, the test result for SARS-CoV-2 diagnostic. Close contacts with a positive test for SARS-CoV-2 were classified as “cases” and those negative as “controls.”ResultsA total of 1,778 close contacts from 463 index patients were identified. No significant differences were observed between the sexes but between age groups. Overall Secondary Attack Rate (SAR) was 24.0% (95% CI: 22.0–26.0%), 36.9% (95% CI: 33.2–40.6%) in closed spaces without ventilation and 50.7% (95% CI: 45.6–55.8%) in exposure time > 24 h. A total of 49.2% of infections occurred among household members. Multivariate logistic regression analysis showed that open-air setting (OR 0.43, 95% CI: 0.27–0.71), exposure for less than 1 h (OR 0.19, 95% CI: 0.11–0.32), and wearing a mask (OR 0.49, 95% CI: 0.28–0.85) had a protective effect transmission of SARS-CoV-2 in the community.ConclusionVentilation of the space, mask-wearing and shorter exposure time were associated with a lower risk of transmission in the community. The data obtained allowed an assessment of community transmission mechanisms and could have helped to improve and streamline tracing by identifying close contacts at higher risk.

Housing conditions can increase health risks for people who use opioids (PWUO). Little research documents the influence of housing on PWUO's ability to practice disease prevention methods. This study examines associations between housing status of PWUO in NYC and their ability to practice COVID-19 prevention recommendations during the initial wave of the pandemic. Participants were recruited via convenience sampling and administered a survey. Eligibility required age ≥18 years, using opioids ≥3times in the prior 30 days, and accessing a health-related service in the prior year. Descriptive and bivariate statistics assessed relationships between housing and the ability to practice social distancing, access soap and running water or hand sanitizer (soap), and access face masks. Multivariable Poisson regression was used to examine relationships between housing and the potential to practice COVID-19 prevention recommendations. The 329 participants were grouped into stable housing (34.3%), unstable/shelter housing (31.9%), and street homeless (33.7%) categories. Street homeless PWUO were significantly less likely to have access to soap and face masks than those stably housed. There were no significant differences between PWUO experiencing unstable and stable housing. PWUO experiencing street homelessness may have had increased vulnerability to COVID-19. Providing low-threshold health-related resources and increasing linkages to housing opportunities could promote health of PWUO experiencing street homelessness during future emergencies.

Background: Hand hygiene plays an important role in the transmission of nosocomial infections from healthcare workers (HCW) to patients. Patients could play a key role in improving hand hygiene by sharing their experience of the HCW’s practices. Already in 2019, the French national mission of transversal support for actions to prevent healthcare-associated infections proposed the national “Pulpe'friction” audit, to assess HCW’s reported practices, social representations, and barriers to using alcohol-based hand rubs (ABHR). This audit consisted of a positive discussion between an auditor and the HCW as well as patients, which led the HCW to declare their real practices and the barriers they faced in the field and the patients to report about the HCW’s ABHR practices and the information they received about when they should perform hand hygiene Objective: To assess whether an association existed between HCW’s reported ABHR compliance and patients’ declarations about HCW’s compliance in the Pulpe’friction audit data. Methods: Data from Pulpe’friction were collected from 1 January to 31 December 2019, before the COVID-19 pandemic. Mixed linear models were performed to analyze the association between self-reporting by HCW and patients, regarding hand rubs performed by HCW prior to patient care. Results: There was a positive association between patients’ observations and HCW’s declared practices regarding the frequency of with which professionals performed hand rubs before patient contact. This indicates that professional and patient statements show the same tendency. The positive association was found in hospitals for patients under 45 and over 64 years old and for paramedics, but not for physicians and not in nursing homes or long-term care facilities. Patients felt more motivated to observe and evaluate HCWs’ practices if they had received information about how to correctly wash their hands. Conclusion: Patients agreed to be involved in the evaluation or professional practices. The patients’ observations were positively associated with HCWs reports. New indicators taking patients’ observations into account could be interesting.

Abstract Background Spread of resistant bacteria causes severe morbidity and mortality. Stringent control measures can be expensive and disrupt hospital organization. In the present study, we assessed the effectiveness and cost-effectiveness of control strategies to prevent the spread of Carbapenemase-producing Enterobacterales (CPE) in a general hospital ward (GW). Methods A dynamic, stochastic model simulated the transmission of CPE by the hands of healthcare workers (HCWs) and the environment in a hypothetical 25-bed GW. Input parameters were based on published data; we assumed the prevalence at admission of 0.1%. 12 strategies were compared to the baseline (no control) and combined different prevention and control interventions: targeted or universal screening at admission (TS or US), contact precautions (CP), isolation in a single room, dedicated nursing staff (DNS) for carriers and weekly screening of contact patients (WSC). Time horizon was one year. Outcomes were the number of CPE acquisitions, costs, and incremental cost-effectiveness ratios (ICER). A hospital perspective was adopted to estimate costs, which included laboratory costs, single room, contact precautions, staff time, i.e. infection control nurse and/or dedicated nursing staff, and lost bed-days due to prolonged hospital stay of identified carriers. The model was calibrated on actual datasets. Sensitivity analyses were performed. Results The baseline scenario resulted in 0.93 CPE acquisitions/1000 admissions and costs 32,050 €/1000 admissions. All control strategies increased costs and improved the outcome. The efficiency frontier was represented by: (1) TS with DNS at a 17,407 €/avoided CPE case, (2) TS + DNS + WSC at a 30,700 €/avoided CPE case and (3) US + DNS + WSC at 181,472 €/avoided CPE case. Other strategies were dominated. Sensitivity analyses showed that TS + CP might be cost-effective if CPE carriers are identified upon admission or if the cases have a short hospital stay. However, CP were effective only when high level of compliance with hand hygiene was obtained. Conclusions Targeted screening at admission combined with DNS for identified CPE carriers with or without weekly screening were the most cost-effective options to limit the spread of CPE. These results support current recommendations from several high-income countries.

Introduction: Hand washing and the use of gloves in accordance with the standards are among the most significant methods used in infection control. Methodology: This study is an analytical cross-sectional study. The sample of the study consisted of 132 health personnel working in the emergency department of a public hospital. Results: The mean of the hand hygiene belief scale was 85.50 ± 8.71, mean of the hand hygiene practice inventory was 67.70 ± 5.19. The participants' mean general attitude towards the use of gloves was 43.71 ± 7.57, the mean of awareness about the use of gloves was 15.17 ± 3.88, the mean attitude towards the usefulness of glove use was 19.43 ± 1.47, and their attitude towards the necessity of using gloves was 12.63 ± 3.57. It was determined that glove usefulness score has a statistically significant and increasing effect on hand hygiene belief, while glove usefulness and glove awareness scores have statistically significant and increasing effects on hand hygiene practice. Conclusions: This study determined that the hand hygiene beliefs and practices of the health personnel working in the emergency department are quite high, their attitudes towards the use of gloves are positive, the attitude towards the usefulness of glove use has a significant and increasing effect on hand hygiene belief, and glove usefulness and glove awareness attitudes have a significant and increasing effect on hand hygiene practice.

Disinfection of gloves might reduce the workload of healthcare workers, protect the environment, and bring economic benefits. Thus, the safety of hand hygiene of gloved hands is an important issue. We aimed to evaluate the risk of microbial transmission by comparing residual micro-organisms after multiple patient contacts, with or without gloves, in clinical practice. Researchers, two with gloved hands (single or double gloves) and one with bare hands, made rounds of patients, followed by alcohol-based hand rub. Hand imprints were obtained before and after the rounds and cultured. The number of colony-forming units (cfu) of gloved and bare hands was compared, and the colony distribution was evaluated semi-quantitatively by hand region. A total of 108 imprints were obtained after 10 rounds. The median cfu counts were significantly higher in the gloved hands (single and double) than in the bare hands (9.00 vs 3.50, P =0.028). The cfu counts of single- and double-gloved hands were higher after than before contact (P =0.044 and P =0.001, respectively). Carbapenem-resistant Acinetobacter baumannii was identified in a pair of double gloves after a round, which included patients with the same organism with identical antibiotic susceptibility results. The mean percentage of colony-growing compartments from gloved hands was significantly higher than that of bare hands in the finger and wrist regions (P =0.019 and P =0.049, respectively). Compared with bare hands, reuse of gloves increased residual microbial colonies and potential for transmission of multi-drug-resistant organisms, even after using alcohol-based hand rub.

Abstract Background Handwashing is important considering the impact of communicable diseases on the public. We aimed to identify the association between years with incidence of communicable diseases during the coronavirus disease 2019 (COVID-19) pandemic and hand hygiene in South Korea. Methods This cross-sectional study evaluated 5 years (2013, 2015, 2017, 2019, and 2020) of data from the Korea Community Health Survey and included 1,034,422 adults. Multinomial logistic regression analysis was performed to assess handwashing frequency by year. Receiver operating characteristic analysis was used to determine the cut-off point for handwashing frequency. Results The always/frequently handwashing rate was 44.7%. This tendency was stronger in adults with each ascending year, with reference to 2013 (2015, odds ratio [OR] = 1.10, 95% confidence interval [CI] = 1.08, 1.13; 2017, OR = 1.10, 95% CI = 1.08, 1.13; 2019, OR = 1.17, 95% CI = 1.14, 1.20; 2020, OR = 3.21, 95% CI = 3.14, 3.29). Among women, the OR of frequently/always handwashing was 3.55 times higher (95% CI = 3.45, 3.66) in 2020 than in 2013. This OR was 2.95 among men (95% CI = 2.86, 3.04). In influenza-vaccinated participants, the OR of frequent/always handwashing was 3.25 times higher in 2020 than in 2013 (95% CI = 3.15, 3.36), while in non-vaccinated participants it was 3.17 (95% CI = 3.08, 3.27). Among adults who practiced physical distancing during the COVID-19 pandemic, the OR was 1.36 times higher (95% CI = 1.29, 1.42) with frequent handwashing, 1.64 times higher (95% CI = 1.57, 1.70) than those who did not practice it. Conclusions There was a strong tendency toward frequent handwashing over the years; the trend was even greater in 2020 during the COVID-19 pandemic. Given that communicable diseases and handwashing are closely related, it is necessary to promote hand hygiene for prevention.

Background: The coronavirus disease (COVID-19) pandemic increased awareness regarding the importance of hand hygiene in infection prevention. Although social distancing and vaccination are the strongest ways to prevent infection, personal hand hygiene is the most basic and easiest way to maintain public health. However, in addition to hand washing using running water, sanitizing tissues, and disinfection products are convenient for hand hygiene, especially outdoors. Therefore, it is necessary to improve the appropriateness of individual hand hygiene methods. In this study, we investigated the degree of hand hygiene offered by various hygiene products and hand drying methods for maintaining hand hygiene.Methods: An LED UV light kit was used for fluorescent observation of hand contamination. Bacteria from the hands were cultured to compare the degree of hand hygiene offered by various hygiene products. Bacteria were cultured in a hand-shaped medium dish to identify areas vulnerable to hand hygiene. Moreover, the degree of hand hygiene was observed according to the drying method using bacterial cultures.Results: We confirmed that hand washing under running water with antibacterial soap, sanitizing with alcohol gel disinfectant, and wiping with antibacterial wet wipes was effective for hand hygiene compared to washing under running water alone. However, for all hygiene products, a large number of bacteria were detected on the fingertips. We verified that natural drying, rather than rubbing, is effective in maintaining hand hygiene.Conclusion: These results suggest that hand hygiene products and drying methods are critical in hand hygiene management. Therefore, these results provide a basis for determining whether an individual’s hand hygiene management method is appropriate.

Abstract Background Hand hygiene (HH) is the most important measure for preventing healthcare-associated infections. A significant correlation between alcohol-based handrub consumption (AHRC) and observed HH compliance rates has been established. In France, publicly reported AHRC displayed a large heterogeneity across healthcare facilities (HCFs). We aimed to describe programmes for promoting HH in the top and medium AHRC scorers and to assess factors and drivers leading to a high AHRC score in a panel of French HCFs. Methods We performed a nationwide qualitative comparative case study based on in-depth semi-structured interviews in 16 HCFs with high, 4-year AHRC scores, and a sample of seven university hospitals (UHs) with medium AHRC scores. Infection Prevention and Control Team (IPC) members (n = 62), quality managers/chief executive officers (n = 23) and frontline workers (n = 6) were interviewed, using a grounded theory approach and an iterative thematic approach. Results Ninety-one interviews were performed. There was a large heterogeneity in IPC structures and objectives, with specific patterns associated with high AHRC that were more organisational than technical. Four areas emerged: (1) strong cohesive team structure with supportive and outcome-oriented work attitude, (2) IPC structure within the organization, (3) active support from the institution, (4) leadership and role model. Among high AHRC scorers, a good core IPC organisation, a proactive and flexible management, a frequent presence in the clinical wards, and working in a constructive safety climate were prominent. Conclusion We highlighted that IPC structure and activity is heterogeneous, with organisational and behavioural characteristics associated with high AHRC score. Beyond technical challenge, our work underlines the importance of strong structure of the IPC and behavioural approaches in implementing key IPC programmes.

COVID-19 infection has been reported to be caused by droplet and contact infection. This paper proposes a model that visualizes the risk of contact infection to family members when viruses spread to various items at home. Behavior data after returning home are extracted from a questionnaire-based survey of home behavior to design the agent-based model. The data tables of contact behavior are created, including the room-to-room transfer probability table, the conditional probability table, and the contact probability table. The material transfer efficiency table is also created by measuring the virus transmission rate after contact with droplets in a virus experiment laboratory. In the experiment, the synthetic agent created from the acquired data probabilistically performs movement and contact behavior after returning home and reproduces the state in which the virus attached to the hand or belongings, when going out, propagates to objects at home. Next, we examine the risk of a second family member returning home. As a result, virus-attached contacts within around 30 minutes after returning home are widely confirmed around the entrance and kitchen, suggesting the effectiveness of early hand-washing behavior. And the experiment shows that even if the first person returning home disinfects their hands inside the entrance, the virus remains in a part of the entrance, and the virus is spread inside the room by the second person returning home.

Background and aimThere are no investigations on hand hygiene during cardiopulmonary resuscitation (CPR), even though these patients are at high risk for healthcare-associated infections. We aimed to evaluate the number of indicated hand hygiene per CPR case in general and the fraction that could be accomplished without delay for other life-saving techniques through standardized observations.Materials and methodsIn 2022, we conducted Advanced Cardiovascular Life Support (ACLS) courses over 4 days, practicing 33 ACLS case vignettes with standard measurements of chest compression fractions and hand hygiene indications. A total of nine healthcare workers (six nurses and three physicians) participated.ResultsA total of 33 training scenarios resulted in 613 indications for hand disinfection. Of these, 150 (24%) occurred before patient contact and 310 (51%) before aseptic activities. In 282 out of 310 (91%) indications, which have the highest impact on patient safety, the medication administrator was responsible; in 28 out of 310 (9%) indications, the airway manager was responsible. Depending on the scenario and assuming 15 s to be sufficient for alcoholic disinfection, 56–100% (mean 84.1%, SD ± 13.1%) of all indications could have been accomplished without delaying patient resuscitation. Percentages were lower for 30-s of exposure time.ConclusionTo the best of our knowledge, this is the first study investigating the feasibility of hand hygiene in a manikin CPR study. Even if the feasibility is overestimated due to the study setup, the fundamental conclusion is that a relevant part of the WHO indications for hand disinfection can be implemented without compromising quality in acute care, thus increasing the overall quality of patient care.

Purpose: The purpose of the study was to find the effectiveness of Extended Infection Control Measures (EICM) in reducing the rate of methicillin-resistant Staphylococcus aureus (MRSA) infection among orthopaedic surgery patients. Methods: The study adopted a quasi-experimental design and was conducted in the orthopaedic units of a tertiary care hospital. This study recruited 168 orthopaedic patients and 154 healthcare professionals (HCPs). EICM included hand hygiene, decolonizing the patients and HCPS, staff education, feedback of surveillance data, treatment of high-risk and MRSA-infected patients, having separate equipment for MRSA-infected patients, and appropriate cleaning of patient's unit. Results: The EICM effectively reduced MRSA infection from 21.2 to 6% (p < 0.001). It also resulted in improving the knowledge of HCPs in the prevention and management of MRSA infection (p < 0.001), and all colonized HCPs were successfully (100%) decolonized. Conclusion: EICM is a promising intervention to combat MRSA infection among orthopaedic wards. Hence, it can be executed in orthopaedic wards, thereby improving the treatment quality and reducing the infection-related consequences. [ABSTRACT FROM AUTHOR]

Background: Although there is no consensus regarding the best skin disinfection technique, whatever antiseptic solution is used, the "prep and drape" portion of most upper extremity procedures requires the presence of at least one operative room assistant or scrub nurse to elevate and hold the hand and forearm. Nonetheless, especially in a busy hand surgery practice and during fast procedures, an operative room assistant or scrub nurse are frequently not available leading to a reduced time efficiency between procedures. Purpose: This article describes an innovative easy-to-use and hands-free device that helps the surgeon during disinfection of the skin and the setup of the surgical field by keeping elevated the upper limb with respect for tissues. Methods: The development of the surgical arm holder starts from three easily available and washable thermoplastic splint sheets 40 × 60 cm with 2.5 cm thickness. The final device measures 40 × 25 × 15 cm and is placed underneath the proximal third of the humerus in order to keep the upper limb suspended at about 10–15 cm from the operating table. A retrospective analysis of the "surgical malpractice claims" and institutional non-conformities registered in the period 2011–2020 was conducted in our Hospital looking for bone or soft tissue complications related to the use of the device. Results: Three thousand one hundred eighty-seven surgical procedures were performed between 2011 and 2020 using this device. The retrospective analysis of all "surgical malpractice claims" showed no skin lesions, no neurological complications (such as neuroapraxia), no need for secondary bone procedures or interference with the draping process. Conclusion: Our device proved to be a low-cost, easy to use and alternative solution helping surgeons during the disinfection phase, improving hospital pre-operative flow and reducing the need for other staff members to be engaged in holding the upper limb in the operating room.

Background: Spread of resistant bacteria causes severe morbidity and mortality. Stringent control measures can be expensive and disrupt hospital organization. In the present study, we assessed the effectiveness and cost-effectiveness of control strategies to prevent the spread of Carbapenemase-producing Enterobacterales (CPE) in a general hospital ward (GW). Methods: A dynamic, stochastic model simulated the transmission of CPE by the hands of healthcare workers (HCWs) and the environment in a hypothetical 25-bed GW. Input parameters were based on published data; we assumed the prevalence at admission of 0.1%. 12 strategies were compared to the baseline (no control) and combined different prevention and control interventions: targeted or universal screening at admission (TS or US), contact precautions (CP), isolation in a single room, dedicated nursing staff (DNS) for carriers and weekly screening of contact patients (WSC). Time horizon was one year. Outcomes were the number of CPE acquisitions, costs, and incremental cost-effectiveness ratios (ICER). A hospital perspective was adopted to estimate costs, which included laboratory costs, single room, contact precautions, staff time, i.e. infection control nurse and/or dedicated nursing staff, and lost bed-days due to prolonged hospital stay of identified carriers. The model was calibrated on actual datasets. Sensitivity analyses were performed. Results: The baseline scenario resulted in 0.93 CPE acquisitions/1000 admissions and costs 32,050 €/1000 admissions. All control strategies increased costs and improved the outcome. The efficiency frontier was represented by: (1) TS with DNS at a 17,407 €/avoided CPE case, (2) TS + DNS + WSC at a 30,700 €/avoided CPE case and (3) US + DNS + WSC at 181,472 €/avoided CPE case. Other strategies were dominated. Sensitivity analyses showed that TS + CP might be cost-effective if CPE carriers are identified upon admission or if the cases have a short hospital stay. However, CP were effective only when high level of compliance with hand hygiene was obtained. Conclusions: Targeted screening at admission combined with DNS for identified CPE carriers with or without weekly screening were the most cost-effective options to limit the spread of CPE. These results support current recommendations from several high-income countries. [ABSTRACT FROM AUTHOR]

Introduction: Sinks have been introduced near patients to improve hand hygiene as part of infection prevention and control measures. However, sinks are a known reservoir for gram-negative bacterial pathogens in particular and their removal to prevent bacterial infections in intensive care patients is currently recommended by several international guidelines., Methods: Healthcare workers (HCWs) in 15 intensive care units (ICUs) in Germany were given the opportunity to complete an anonymous survey on the use of sinks between August 2022 and January 2023. Observations were then made in three participating ICUs to determine the frequency and reason for contact with the sink., Results: 258 questionnaires were returned (nurses 87%). 90% found it useful to very useful to have a sink in the patient room, and 56% reported using it daily for hand hygiene. We observed 33 contacts between nurses and sinks over 17 h. In 20/33 (60%) cases, the sink was used for waste disposal. In 3/33 (10%) it was used for hand washing., Discussion: Sinks are still used for daily care in intensive care units. Educational Interventions in existing buildings to minimise risk through "sink hygiene" (i.e. separation of sinks for water disposal and uptake) can make an important contribution to infection prevention., Competing Interests: Declarations Competing interests The authors declare no competing interests.

Good hand-washing practice is the most important preventive measure to reduce the spread of communicable disease to under-five children. Prior studies on good handwashing practice at critical times among mothers of children under-five age in Ethiopia were extremely varied. Therefore, this meta-analysis aimed to assess the overall proportion of good handwashing practice at critical times and identify the associated factors in Ethiopia. A comprehensive search of relevant studies was performed using distinct databases. Data were extracted using Microsoft Excel spreadsheet, and exported to Stata-MPv-17 for analysis. A random-effect model was used to estimate the overall proportion of good hand-washing practice at critical times. A random or fixed effects model was used to compute the pooled AORs with their 95% Cis, which were presented on a forest plot. I 2 test statistics was used for assessing heterogeneity among the included studies. The funnel plot and Egger's test were used to assess the publication bias. Ten studies were included in this systematic review and meta-analysis. The overall pooled proportion of good hand-washing practice at critical times among mothers of children under-five age in Ethiopia was 43.18% (95% CI = 31.05, 55.31). Insufficient water (AOR = 0.33, 95% CI: 0.13, 0.52), good knowledge (AOR = 1.35, 95% CI = 1.09, 1.61), desirable attitude (AOR = 4.34, 95% CI = 1.84, 6.84) and higher educational level (AOR = 0.17, 95% CI = 0.08, 0.25) were significantly associated with good practice of hand-washing at critical times. The national level of good practice of hand-washing at critical times was low. Hence, to promote good practice of hand-washing, it is essential to increase the accessibility of water and provide hygiene health education and training programs to improve knowledge and desirable attitudes of mothers., (© 2024.

Contaminated hands of people and contaminated surfaces of inanimate objects (fomites) can spread microbes that cause enteric and respiratory infections. Thus, hand hygiene and surface hygiene are probably the most widely adopted public health interventions for controlling such infections. However, conclusions of studies on the effectiveness of these interventions are often inconsistent, likely because such studies have examined these interventions separately and thus not detected their interactions, leading to differing conclusions about their individual impact. In this study, it is proposed that hand and environmental surface hygiene (including disinfection) should be coupled to control contamination spread between surfaces, especially within heterogeneous surface touch networks. In these networks, surfaces and individuals have varying contact frequencies and patterns, reflecting the diverse and non-uniform interactions that typically occur in real-world environments. Accordingly, we propose a new theoretical framework to delineate the relationships between hand hygiene and surface hygiene. In addition, the performance of a model based on this framework that used real-world behavioural data from a graduate student office is reported. Moreover, a coupled hygiene criterion for heterogeneous networks is derived. This criterion stipulates that the product of the pathogen-removal rates for hands and surfaces must exceed a cleaning threshold to ensure the exponential decay of contamination. Failure to meet this threshold results in a non-zero steady prevalence of contamination. Furthermore, the cleaning threshold increases as the numbers of surfaces and hands increase, highlighting the significant impact of network structures on hygiene practices. Thus, extensive cleaning may be necessary in crowded indoor environments with many surfaces and occupants, such as cruise ships, to prevent super-large outbreaks of, for example, noroviral infections. Overall, the findings of this study reveal how improved and integrated hygiene control can prevent fomite transmission., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Background: The skin microbiota maintains a physical and immunological barrier to the environment. Little is known about how the microbiome changes over time or the effect of hand hygiene practices and moisturizer use., Objectives: To assess sex-specific changes in skin bacteria over time, and how the microbiome is related to self-reported hand eczema, hand hygiene practices and use of moisturizers., Methods: Swab samples from the dorsal hand were collected at baseline and 6.5 years later during the COVID-19 pandemic, in 168 participants from the RHINESSA study in Bergen, Norway. The skin samples were analysed by 16S rRNA amplicon sequencing., Results: The alpha diversity of the hand microbiome increased from baseline to follow-up, and beta diversity differed by sex at both time points. The relative abundance increased for several bacteria from baseline to follow-up, with sex-specific differences. Current hand eczema and aggravating hand eczema during the COVID-19 pandemic were associated with an increase in Staphylococcus. High hand washing frequency at home was associated with lower alpha diversity and with higher abundance of Staphylococcus, Corynebacterium, Finegoldia, and Pseudomonas and lower abundance of Propionibacterium and Pelomonas. The alpha diversity increased with increasing time passing between hand washing and sampling, whereas more frequent moisturizer use was associated with significantly lower alpha diversity, and a change in abundance for some bacteria, such as more Pseudomonas., Conclusions: This longitudinal study revealed an overall increase in skin microbial diversity over a 6-year period, which was unexpected since follow-up was performed during the COVID-19 pandemic when vigorous hand hygienic practices were introduced. Sex-specific differences were identified at both time points. Individuals with hand eczema seem to develop a more dysbiotic skin bacterial community over time. Hand washing and use of moisturizers, with typically gender-specific habitual patterns, may lead to change in bacterial composition., (© 2024 The Authors.

Background: Increasingly, hospital handwashing basins have been identified as a source of healthcare-associated infections. Biofilms formed on the faucet and drains of handbasins can potentially harbour pathogenic microbes and promote the dissemination of antimicrobial resistance. However, little is known about the diversity of these biofilm communities and the routes of contamination., Aim: The aim of this paper was to use 16S rRNA gene amplicon sequencing to investigate the diversity of prokaryote communities present in faucet and drain biofilm samples taken from hospital and residential handbasins., Findings: The biofilm prokaryotes communities were diverse, with high abundances of potentially corrosive, biofilm forming and pathogenic genera, including those that are not typically waterborne. The β-diversity showed statistically significant differences in the variation of bacterial communities on the basis on building type (hospital vs residential p = 0.0415). However, there was no statistically significant clustering based on sampling site (faucet vs drain p = 0.46). When examining the β-diversity between individual factors, there was a significant difference between drain biofilms of different buildings (hospital drain vs residential drain p = 0.0338)., Conclusion: This study demonstrated that biofilms from hospital and residential handbasins contain complex and diverse microbial communities that differ significantly by building type. It also showed biofilms formed on the faucet and drain of a hospital's handbasins were not significantly different. Future research is needed to understand the potential mechanisms of transfer between drains and faucets of hospital handbasins. This information will inform improved infection control guidelines to control this underrecognized source of infections., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Claire Hayward reports financial support was provided by Enware Australia Pty Ltd.

Despite a downward trend, Ethiopia still faces significant challenges with high rates of stunting and acute malnutrition in children. To tackle these issues, the Feed the Future Ethiopia Growth Through Nutrition Activity, a USAID-funded project aligned with Ethiopia's National Nutrition Program, was executed from 2016 to 2023. This initiative aimed to enhance nutrition for women and young children across six regions through multisectoral interventions. Annual surveys conducted in 2017, 2018, and 2020 evaluated the impact of livelihood support and Water, Sanitation, and Hygiene (WASH)-focused social behavior change communication (SBCC) on vulnerable households with children under two. The results showed significant improvements in child nutrition. Dietary diversity among children increased from 12% to 34% (p<0.001), and the percentage of children receiving a minimal acceptable diet rose from 12% to 30.7% (p<0.001). Women's dietary diversity also improved markedly, from 2% to 16% (p<0.001). Handwashing practices saw improvements, with the proportion of households having handwashing facilities rising from 14% to 31% (p<0.001), and the adherence to critical handwashing moments increased from 16% to 23%. However, challenges in water treatment and latrine use persisted, with less than 25% improvement. The findings suggest that integrating livelihood support with SBCC interventions can positively enhance nutritional outcomes. Continued focus on these strategies is recommended to further support vulnerable households., Competing Interests: The authors have declared that no competing interests exist., (Copyright: This is an open access article, free of all copyright, and may be freely reproduced, distributed, transmitted, modified, built upon, or otherwise used by anyone for any lawful purpose.

Background: Over 1.7 billion instances of diarrheal illness in children are reported worldwide yearly. Diarrhea was a major cause of death in children, accounting for 9% of all global under-five child deaths in 2021. The objective of this study was to identify the association between hygiene practices and childhood diarrhea among under-five children in Myanmar., Method: This cross-sectional study was conducted in 16 townships from 8 states and regions of Myanmar. 1207 children between the ages of 6 and 59 months were recruited by multistage random sampling. Data were collected with a preformed questionnaire after participants provided consent. Multiple logistic regressions were administered to determine the factors associated with childhood diarrhea., Result: This study found that 86 (7.13%) under-five children experienced diarrhea disease. This study identified that children receiving limited hygiene services were 2.85 times (AOR = 2.85, 95% CI: 1.31 to 6.21; p value 0.01) and children without hygiene services were 2.63 times (AOR = 2.63, 95% CI: 1.42 to 4.89; p value 0.01) more likely to have diarrhea disease than those with basic hygiene services. Other factors associated with diarrhea included: fathers who washed their hands less than four steps (AOR = 2.20, 95% CI: 1.29 to 3.74; p value 0.01), families taking more than 15 min to collect water (AOR = 1.77, 95% CI: 1.06 to 2.97; p value 0.03), families sharing toilet usage (AOR = 2.00, 95% CI: 1.15 to 3.48; p value 0.01), mother's inadequate and problematic hygiene promotion health literacy (AOR = 2.20, 95% CI: 1.24 to 3.90; p value 0.01), houses made of bamboo or lacking floors (AOR = 2.31, 95% CI: 1.38 to 3.89; p value 0.01), families with three or more children (AOR = 1.68, 95% CI: 1.01 to 2.79; p value 0.05) and breastmilk being the primary food after 6 months of age (AOR = 2.07, 95% CI: 1.09 to 3.93; p value 0.03)., Conclusions: Ensuring access to basic hygiene services, getting water at home 24 h per day, seven days per week, using private toilets, promoting hygiene health literacy, improving house flooring, family planning and introducing a variety of foods after age 6 months could significantly prevent diarrhea among under-five children in Myanmar. This study underscores the critical role of handwashing facilities in reducing the diarrhea incidence in children., (© 2024. The Author(s).)

Introduction: The extent to which sinks are contaminated by carbapenem-resistant Acinetobacter baumannii (CRAB) in intensive care units (ICUs) and the association between these contaminated sinks and hospital-acquired CRAB infections during the non-cluster period remains largely unknown. Here, we performed a prospective multicenter study in 16 ICUs at 11 tertiary hospitals in Chengdu, China., Methods: We sampled sinks, collected CRAB clinical isolates, and conducted whole-genome sequencing and analysis., Results: A total of 789 swabs were collected from 158 sinks, and 16 CRAB isolates were recovered from 16 sinks, resulting in a contamination rate of 10.16%. Twenty-seven clinical isolates were collected during the study period. The majority (97.67%, 42/43) of the CRAB isolates belonged to ST2, and 36 (83.72%) of them had both bla OXA-23 and bla OXA-66 . The 43 strains belonged to 12 clones. One certain clone caused multiple contaminations of seven sinks in one GICU. Two clones of ST2 bla OXA-23 and bla OXA-66 -carrying sink strains were likely the sources of the two clusters in the two GICUs, respectively. Five ST2 bla OXA-23 -carrying isolates were found to be common clones but were recovered from two hospitals., Conclusion: The contamination rate of CRAB in handwashing sinks is high in some local ICUs, and the contaminated sinks can serve as environmental reservoirs for CRAB clusters., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Wei, Feng, Lin, Kang, Zhuang, Wen, Ran, Zheng, Zhang, Xiang, Liu, Wu, Duan, Zhang, Li, Guo, Tao and Qiao.)

Children are susceptible to infections due to frequent participation in school group activities and their often-suboptimal hygiene practices. Frequent infections in children affect school attendance, academic performances, and general health. The effectiveness of school-based hygiene-related intervention programmes need to be informed by updated high-quality synthesised evidence. In this systematic review, we searched PubMed and Cochrane CENTRAL for randomised and non-randomised interventional studies that evaluated school-based hygiene-related interventions. We assessed risk-of-bias (Cochrane risk-of-bias 2 tool), performed random-effect meta-analysis (RevMan 5.4) and rated certainty-of-evidence (GRADE). Thirty-nine trials (41 reports), published from 2011 to 2024 from 22 countries were included. Twenty-three studies contributed data for meta-analysis. All school-based interventions were compared with standard curriculum and demonstrated very low to low certainty-of-evidence due to study methodological limitations and imprecision. Hand-body hygiene interventions may improve knowledge, attitudes and practices (SMD 2.30, 95%CI 1.17 to 3.44, 6 studies, 7301 participants), increase handwashing practices (RR 1.75, 95%CI 1.41 to 2.17, 5 studies, 5479 participants), and reduce infection-related absenteeism (RR 0.74, 95%CI 0.66 to 0.83, 5 studies, 1017852 observations). Genital hygiene interventions may improve attitude (SMD 6.53, 95%CI 2.40 to 10.66, 2 studies, 2644 participants) and practices (RR 2.44, 95%CI 1.28 to 4.68, 1 study, 1201 participants). However, intervention effects on oral hygiene appeared mixed, with worsening of the oral hygiene score (SMD 3.12, 95%CI 1.87 to 4.37, 2 studies, 652 participants) but improved dental hygiene (SMD -0.33, 95%CI -0.53 to -0.13, 3 studies, 4824 participants) and dental caries scores (SMD -0.34, 95%CI -0.52 to -0.16, 4 studies, 2352 participants). Limited evidence suggests that interventions targeting hand-body and genital hygiene practices may improve knowledge, practices, and infection-related absenteeism. However, the effects on oral hygiene intervention appeared mixed.

Background & Objective: Tuberculosis (TB) is endemic in India. TB is transmitted through droplet infection and the transmission occurs when a person inhales droplet nuclei containing of Mycobacterium tuberculosis. Infection control practices play a major role in controlling the TB infection in healthcare settings and further prevents TB infection in the HCWs. The aim of the study is to conduct the cross sectional study for infection control practices in DOTS cum Sputum Microscopy Centre's under NTEP in Ghaziabad (Uttar Pradesh) & Dehradun (Uttarakhand) districts with the objective to assess the compliance of infection control measures by HCWs in DOTS cum Sputum Microscopy Centre's and to suggest the suitable measures and/or model to reduce the transmission of infection to the HCWs and to the community at large., Materials & Methods: The cross sectional study is conducted for two years in two districts of different state having high burden of TB disease in UP and low burden of disease in UK state. All DOTS cum Sputum Microscopy centres of both selected districts i.e. 100% sample size are covered in the study., Results: Hand washing is the most efficient and cost-effective practice for prevention and control of infection. In Dehradun district 66.66% (12) centers and in Ghaziabad district 57.14% (16) centers have adequate hand washing facility available at DOTS and sputum microscopy lab. Unavailability of adequate PPE will lead to the infection. In Dehradun district, 55.56% (10) centers have adequate PPE available whereas in Ghaziabad District 21.43% (6) centers have adequate PPE available. Training on infection prevention and control for HCWs are provided in 27.78% (5) DOTS/sputum microscopy center in Dehradun whereas none of the DOTS/sputum microscopy center in Ghaziabad district are given training on infection prevention & control for HCWs in last one year. Adequate ventilation plays an important role in transmission of TB/MDR TB or any respiratory infection. HCWs working in DOTS/Sputum microscopy center are at risk to contact the TB/MDR TB infection if there is no proper ventilation in their working places. In 33.33% (6) DOTS/sputum microscopy center in Dehradun & 28.57% (8) in Ghaziabad district have adequate ventilation. Layout of DOTS room and for sputum microscopy center are suggested to reduce the risk of transmission of TB/MDR-TB and other respiratory pathogens amongst HCWs who are working in DOTS cum sputum microscopy center., Conclusion: DOTS cum Sputum Microscopy Centers of both districts in different states are having deficient infection control practices. Staff is not adequately trained in infection prevention and control practices., Competing Interests: Conflicts of interest The authors have none to declare., (Copyright © 2023 Tuberculosis Association of India.

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.

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., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 McNicholl, Younie, Crosby and Laird.)

Background: Soil-transmitted helminthes (STH) infections are one of the most common neglected tropical diseases. It has become one of a significant public health problem programmatically aimed for prevention and control in Ethiopia. Limited evidence is available on communities' knowledge, perceptions, and practices regarding STH particularly in rural settings of Jimma, Ethiopia., Methods: A community-based cross-sectional study triangulated with the qualitative method was conducted. The survey included 732 sampled rural households. Linear regression was used to assess association between predictors of knowledge and preventive practices of STH; likewise logistic regression was used to identify the predictors of hand washing practice at critical times. Kruskal-Wallis and Mann-Whitney tests were done to test differences in median risk perception score by socio-demographic factors. Qualitative data were collected through 7 key informant interviews, 6 focus group discussions and 7 expert group discussions then transcribed verbatim. Then, the data were coded, categorized and thematized using the Atlas ti.7.1.4 software package., Results: Almost all of the respondents (99.6%) had heard of STH. The prevalence of comprehensive knowledge, risk perception and preventive practices towards STH were 46.7%:(95%CI:43.2, 50.4), 55.2%: (95%CI:51.2,59) and 44.4%:(95%CI:40.8, 48.2) respectively. Likewise, the magnitude of knowledge and practice of hand washing at critical times were 42.5%: (95%CI: 38.7,45.9) and 43.9%: (95%CI: 40, 47.5) respectively. Risk perception and comprehensive knowledge towards STH varied significantly across districts and by respondents' educational status. Ownership of improved latrine was associated to comprehensive knowledge of STH. The STH preventive practice that varied across districts was predicted by the overall and knowledge specific to washing hands at critical times. The practice of washing hands at critical times was significantly associated to knowledge of hand washing, owning improved latrine, and age from 15 to 34 year compared to >45 year. Moreover, qualitative findings were supportive of the findings., Conclusion: Despite reported exposures to STH communication opportunities, the study found modest levels of knowledge, perceptions, and preventive practices related to STH among rural communities where the burden of STH was the programmatic concern. These levels of knowledge, perceptions, and practices varied across the districts. Educational and latrine status predicted overall knowledge, whereas knowledge specific to hand washing and overall knowledge were predictors of STH preventive practice. Furthermore, washing hands during critical times was moderately improved among the young-aged, ownership of improved latrine and knowledgeable on hand washing. This study underscores the need for locally tailored and contextualized community behavioral change interventions needs to be strengthened toward improved STH preventive practices., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Abdissa et al.

Background: Hospitals should prepare for emerging diseases and protect healthcare workers (HCWs) from work-related infection. This study aims to assess public hospital preparedness for the coronavirus disease 2019 (COVID-19) a year after the Myanmar government began implementing COVID-19 prevention measures, and to identify factors associated with work-related COVID-19 infection among HCWs in Myanmar., Methods: In January 2021, data were collected from 101 hospitals and 706 HCWs who had COVID-19 in Myanmar in 2020. Data from the hospitals included basic information, the status of infection prevention and control (IPC), the preparedness for COVID-19 (guidelines, checklists, fever screening, patient pathway, and training), handwashing facilities, and availability of personal protective equipment (PPE). Data of COVID-19 infected HCWs included age, occupation, workplace, severity and source of COVID-19 infection, knowledge and practice of handwashing, and working environment. Chi-square test was performed to compare the preparedness for COVID-19 among three hospital levels (primary, secondary and tertiary levels). Logistic regression analysis was performed to identify the associated factors of work-related infection of HCWs., Results: The total number of beds, HCWs, and COVID-19 patients in 2020 at the 101 hospitals was 12,888, 14,421, and 19,835, respectively. The availability of PPE was high in hospitals at all levels. Approximately 80% of hospitals had functional status of IPC, set up fever screening and patient pathway, and provided training on IPC and COVID-19. However, only 39.6% of hospitals had developed COVID-19 guidelines and 55.4% had developed checklists. The percentage of hospitals that prepared each measurement was lowest at the primary level. The factors associated with work-related COVID-19 among HCWs were being 30-39 years old, working as a doctor, working at isolation wards, having disinfection technique training, and having enough PPE at the workplace., Conclusion: The preparedness for COVID-19 at public hospitals in Myanmar in January 2021 was insufficient, especially in the availability of the guidelines and checklists and at primary hospitals. A support system for hospital pandemic preparedness and monitoring of IPC implementation is needed. The government should prepare for emerging diseases and provide appropriate and adequate PPE and additional training to all HCWs, especially HCWs who work for isolation wards., (© 2024.

This study assesses the impact of financial incentives on hygienic latrine ownership by poor/near-poor households in Vietnam. Rural communes were randomly assigned to a control group and three treatment arm groups: (T1) a rebate for households that installed a hygienic latrine; (T2) a financial reward for commune governments if the proportion of hygienic latrines in their commune increased by 30 percentage points; (T3) both a household rebate and a commune reward. We find a strong and positive effect from the household rebate (treatment arms 1 and 3) but an insignificant effect from the commune reward (treatment arm 2) on household ownership of a septic tank latrine. Our analysis provides suggestive evidence that microcredit is a channel through which a rebate encourages the installation of septic tank latrines. We also find that treatment arm 3 increases people's knowledge regarding sanitation and the availability of water and soap for handwashing within households., (Copyright © 2024 Elsevier B.V.

We report on testing 100 individuals for their shedder status with the aim of demonstrating whether the process of cell staining is reproducible when testing a large number of people. A previous report using the same method was based on 11 donors and indicated that there may be a continuum of shedder types within this small sample set. In this report we also expand the time points post-handwashing to 0, 15, 30, 60, and 180 min. Triplicate samples were collected from both the right and left thumbs. Samples were collected by donors placing a thumb on a clean glass slide and then adding a DNA binding dye. The number of cells were recorded within three separate square millimetre areas (cells/mm 2 ) at 220x magnification. The experiments were conducted in triplicate on three different days, giving a total of 72 thumbprints per individual. Finally, there were 3438 observed frames in the entire dataset. Of the 100 donors, 98 gave consistent and reproducible cell number deposition. There was no difference between the cells deposited by the left and right thumbs in 13 of 15 tested. Males tended to deposit more cells than females. If applying arbitrary boundary to a cell count to definitively determine shedder status, then many of the donors fell within two categories. This study based on 100 individuals strongly suggests that shedder status is a continuum phenomenon., Competing Interests: Declaration of Competing Interest None., (Copyright © 2024 The Authors.

Health care systems, including operating rooms, are a considerable contributor to environmental waste. Given ongoing concerns regarding water scarcity in the United States and worldwide, action to reduce water utilization should be taken. Traditional water-based hand scrubbing wastes an estimated 11 L of water per scrub. Waterless hand rubbing with an alcohol-based solution has been shown to be as effective as traditional water-based hand scrubbing in surgical hand antisepsis and in preventing surgical site infections. Furthermore, alcohol-based rubbing results in less waste and reduced costs when compared with water-based hand scrubbing. The hand surgery operating room, including minor procedure rooms, serves as an opportunity to decrease water use and reduce the environmental impact of our field. Waterless alcohol-based hand rubbing for antisepsis may also be an opportunity to save money and provide value-based care to our patients., Competing Interests: Conflicts of Interest Dr R.
