Impact of COVID-19 health precautions on asymptomatic Streptococcus pyogenes carriage in palestinian children: a pre- and post-pandemic study.

BACKGROUND: Streptococcus pyogenes (Group A Streptococcus, GAS) is a significant pathogen that causes diverse infections, ranging from pharyngitis to severe invasive diseases. Asymptomatic carriage in children is pivotal for transmission. The COVID-19 pandemic's health measures, including mask wearing and enhanced hand hygiene, likely influenced GAS transmission dynamics. This study evaluated the impact of these precautions on the prevalence of asymptomatic pharyngeal GAS carriage among schoolchildren in the southern West Bank, Palestine. METHODS: This cross-sectional study was conducted in two phases: pre-COVID-19 (November 2019-January 2020) and post-COVID-19 (November 2023-April 2024). Throat swabs were collected from 701 children (345 pre-COVID-19, 356 post-COVID-19) via cluster sampling. The samples were tested with the ABON Strep A rapid test and confirmed by culture. Sociodemographic, health, and household data were also collected. The statistical analyses included descriptive statistics, chi-square tests, and binary logistic regression. RESULTS: The prevalence of asymptomatic pharyngeal GAS carriage declined from 15.7% pre-COVID-19 to 10.4% post-COVID-19 (p = 0.038). Significant reductions were observed among urban residents (23.5-10.1%, p = 0.003) and those from medium socioeconomic backgrounds (16.0-9.1%, p = 0.008). Compared with urban residents, rural residents had lower GAS carriage rates (adjusted OR = 0.505, p = 0.023). Carriage rates also decreased among children with frequent sore throats (17.6-7.3%, p = 0.007) and those using private wells (52.5-14.9%, p < 0.001). Higher BMI was a significant risk factor (adjusted OR = 17.68, p < 0.001), whereas frequent tooth brushing (adjusted OR = 0.055, p < 0.001) and hand washing (adjusted OR = 0.367, p < 0.001) were protective factors. CONCLUSIONS: COVID-19-related health precautions were correlated with a significant reduction in asymptomatic GAS carriage among Palestinian children. These findings suggest that public health measures, such as mask wearing and hand hygiene, can influence the transmission of respiratory pathogens. Ongoing surveillance and targeted interventions are essential for managing GAS infections, particularly in resource-limited settings.

The state of hand rub dispensers in healthcare settings - a multicenter assessment in 19 German healthcare facilities.

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.

Application of the behaviour-centred design to understand facilitators and deterrents of hand hygiene among healthcare providers: findings from a formative phase of a cluster randomised trial in the Kampala Metropolitan area.

BACKGROUND: Hand hygiene is known to reduce healthcare-associated infections. However, it remains suboptimal among healthcare providers. In this study, we used the Behaviour-centered Design approach to explore the facilitators and deterrents to hand hygiene among healthcare providers in the Kampala Metropolitan area, Uganda. METHODS: We conducted a formative qualitative study as part of a cluster randomised trial in 19 healthcare facilities (HCFs). The study used 19 semi-structured and 18 key informant interviews to collect data on hand hygiene status and facilitators and deterrents of hand hygiene. Research assistants transcribed verbatim and used a thematic framework aided by Nvivo 14.0. to undertake analysis. We used thick descriptions and illustrative quotes to enhance the credibility and trustworthiness of our findings. RESULTS: About 47.4% of the HCFs had sufficient hand hygiene infrastructure, and 57.9% did not report total compliance with hand hygiene during patient care. The physical facilitator for hand hygiene was the presence of constant reminders such as nudges, while the biological included the frequency of patient contact and the nature of clinical work. The only biological deterrent was the heavy workload in HCFs. The executive brain facilitators included knowledge of workplace health risks, infection prevention and control (IPC) guidelines, and a positive attitude. A negative attitude was the executive brain deterrent to hand hygiene. Recognition, rewards, and fear of infections were the only motivated brain facilitators. Behavioural setting facilitators included proximity to functional hand hygiene infrastructure, the existence of active IPC committees, good leadership, and the availability of a budget for hand hygiene supplies. Behavioural setting deterrents included the non-functionality and non-proximity to hand hygiene infrastructure and inadequate supplies. CONCLUSIONS: The study revealed low compliance with hand hygiene during the critical moments of patient care and inadequacy of hand hygiene infrastructure. The deterrents to hand hygiene included a heavy workload, negative attitude, inadequate supplies, non-functionality, and long distance to hand washing stations. Facilitators included constant reminders, fear of infections, frequency of patient contact and nature of clinical work, positive attitude, knowledge of IPC guidelines, recognition and reward, good leadership, availability of budgets for hand hygiene supplies, availability and proximity to hand hygiene supplies and infrastructure and active IPC committees. TRIAL REGISTRATION: ISRCTN Registry with number ISRCTN98148144. The trial was registered on 23/11/2020.

Digital health literacy, behavior and knowledge of adolescents for hand hygiene during the COVID-19 pandemic.

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.

Hand and environmental hygiene: respective roles for MRSA, multi-resistant gram negatives, Clostridioides difficile, and Candida spp.

Healthcare-associated infections (HAIs) caused by multidrug-resistant organisms (MDROs) represent a global threat to human health and well-being. Because transmission of MDROs to patients often occurs via transiently contaminated hands of healthcare personnel (HCP), hand hygiene is considered the most important measure for preventing HAIs. Environmental surfaces contaminated with MDROs from colonized or infected patients represent an important source of HCP hand contamination and contribute to transmission of pathogens. Accordingly, facilities are encouraged to adopt and implement recommendations included in the World Health Organization hand hygiene guidelines and those from the Society for Healthcare Epidemiology of America/Infectious Diseases Society of America/Association for Professionals in Infection Control and Epidemiology. Alcohol-based hand rubs are efficacious against MDROs with the exception of Clostridiodes difficile, for which soap and water handwashing is indicated. Monitoring hand hygiene adherence and providing HCP with feedback are of paramount importance. Environmental hygiene measures to curtail MDROs include disinfecting high-touch surfaces in rooms of patients with C. difficile infection daily with a sporicidal agent such as sodium hypochlorite. Some experts recommend also using a sporicidal agent in rooms of patients colonized with C. difficile, and for patients with multidrug-resistant Gram-negative bacteria. Sodium hypochlorite, hydrogen peroxide, or peracetic acid solutions are often used for daily and/or terminal disinfection of rooms housing patients with Candida auris or other MDROs. Products containing only a quaternary ammonium agent are not as effective as other agents against C. auris. Portable medical equipment should be cleaned and disinfected between use on different patients. Detergents are not recommended for cleaning high-touch surfaces in MDRO patient rooms, unless their use is followed by using a disinfectant. Facilities should consider using a disinfectant instead of detergents for terminal cleaning of floors in MDRO patient rooms. Education and training of environmental services employees is essential in assuring effective disinfection practices. Monitoring disinfection practices and providing personnel with performance feedback using fluorescent markers, adenosine triphosphate assays, or less commonly cultures of surfaces, can help reduce MDRO transmission. No-touch disinfection methods such as electrostatic spraying, hydrogen peroxide vapor, or ultraviolet light devices should be considered for terminal disinfection of MDRO patient rooms. Bundles with additional measures are usually necessary to reduce MDRO transmission.

Electronic monitoring versus manual paper-based monitoring for hand hygiene compliance: a comprehensive health economic assessment analysis.

BACKGROUND: Monitoring hand hygiene compliance (HHC) of healthcare providers (HCPs) in healthcare facilities is critical for hand hygiene (HH) promotion. However, less is known about the cost and effectiveness of different HHC monitoring tools. In this study, we aimed to compare various health economic indicators corresponding to electronic system-based monitoring (ESM) and manual paper-based monitoring (MPM) for HHC to provide evidence-based advice for HHC monitoring measures targeted selecting. METHODS: A before and after study in 40 clinical departments with 4,524 healthcare providers was conducted from December 2022 to January 2023 (MPM implementation phase) and March 2023 to May 2023 (ESM implementation phase). The cost-effectiveness, cost-efficiency, the extent of the Hawthorne effect, and indirect cost-benefit of the two monitoring methods were compared. RESULTS: The total cost spent on ESM for the 40 departments (17,702.92 CNY) was 4,123.76 CNY lower than that of MPM (21,826.68 CNY). The HHC of MPM (80.16%) was higher than that of ESM (69.82%) (p < 0.01). In high- and medium-risk departments, the cost-effectiveness ratio of ESM (7,977.90 CNY and 13,794.60 CNY, respectively) was lower than that of MPM (9,039.61 CNY and 14,549.05 CNY, respectively). In low-risk departments, the cost-effectiveness ratio of ESM (3,910.77 CNY) was higher than that of MPM (3,899.06 CNY). Compared with ESM, the incremental cost of MPM in all departments was 4,123.76 CNY, the incremental effectiveness was 10.34%, and the incremental cost-effectiveness ratio was 39,881.62 CNY. Between the two monitoring methods, the efficiency of ESM (48.11%) in all departments was higher than that of MPM (14.20%) (p < 0.01). The cost-efficiency ratio of MPM in all departments (155,775.56 CNY) was higher than that of ESM (36,796.76 CNY). The extent of Hawthorne effect of MPM of HHC in all departments (43.99%) was higher than that of ESM (35.69%) (p < 0.01). When ESM was used as the HHC monitoring approach, the HAI rates (1.39%) in all departments were higher than that when MPM was used (1.34%) (p = 0.562). When the payment willingness was less than 40,000 CNY, the ESM method was the better option for cost-effectiveness; When the input exceeded this threshold, the MPM method was the better option for cost-effectiveness. CONCLUSIONS: ESM exhibited notable advantages over MPM in terms of cost-effectiveness, cost-efficiency, cost-benefit, and the Hawthorne effect.

Adapting the WHO hand hygiene 'reminders in the workplace' to improve acceptability for healthcare workers in maternity settings worldwide: a mixed methods study.

INTRODUCTION: Hand hygiene is key in preventing healthcare-associated infections, but it is challenging in maternity settings due to high patient turnover, frequent emergencies and volume of aseptic procedures. We sought to investigate if adaptions to the WHO hand hygiene reminders could improve their acceptability in maternity settings globally, and use these findings to develop new reminders specific to maternity settings. METHODS: Informed by Sekhon et al's acceptability framework, we conducted an online survey, semi-structured interviews and a focus group examining the three WHO central hand hygiene reminders ('your five moments of hand hygiene', 'how to hand wash' and 'how to hand rub') and their acceptability in maternity settings. A convergent mixed-methods study design was followed. Findings were examined overall and by country income status. A WHO expert working group tested the integrated findings, further refined results and developed recommendations to improve acceptability for use in the global maternity community. Findings were used to inform the development of two novel and acceptable hand hygiene reminders for use in high-income country (HIC) and low- and middle-income country (LMIC) maternity settings. RESULTS: Participation in the survey (n=342), semi-structured interviews (n=12) and focus group (n=7) spanned 51 countries (14 HICs and 37 LMICs). The highest scoring acceptability constructs were clarity of the intervention (intervention coherence), confidence in performance (self-efficacy), and alignment with personal values (ethicality). The lowest performing were perceived difficulty (burden) and how the intervention made the participant feel (affective attitude). Overfamiliarity reduced acceptability in HICs (perceived effectiveness). In LMICs, resource availability was a barrier to implementation (opportunity cost). Two new reminders were developed based on the findings, using inclusive female images, and clinical examples from maternity settings. CONCLUSION: Following methodologically robust adaptation, two novel and inclusive maternity-specific hand hygiene reminders have been developed for use in both HIC and LMICs.

The Effect of Simulation-Based Training on the Hand Hygiene Knowledge and Practices of Palliative Caregivers: A Double-Blind, Randomized, Controlled Single-Center Study.

This study aimed to investigate the effect of simulation-based training on hand hygiene knowledge and practices among palliative caregivers. The study was conducted with 60 caregivers in a palliative care clinic between December 2022 and September 2023. The participants were divided into two groups by simple randomization. The intervention and control groups received the same hand hygiene theoretical education and demonstration. The intervention group also received additional simulation-based hand hygiene practices recommended by the World Health Organization. A pretest-posttest design was used to assess hand hygiene knowledge and practices. Data were collected with personal information, hand hygiene knowledge, and hand hygiene practice forms. Analysis of covariance was performed to compare posttest scores between the groups. Simulation-based hand hygiene training programs offer an effective and feasible strategy to improve the hand hygiene knowledge and practices of caregivers. It should be integrated into clinical areas to increase palliative caregivers' hand hygiene knowledge and practices. Evidence-based practices can be improved by increasing randomized controlled studies on the effectiveness of simulation-based hand hygiene training for caregivers. Trial Registration: The study was registered at ClinicalTrials.gov with registration number NCT05848596.

Infection prevention and control: critical strategies for nursing practice.

Infection prevention and control (IPC) is essential in nursing practice to safeguard patient health and reduce healthcare-associated infections. This article explores IPC strategies, including hand hygiene, the use of personal protective equipment, environmental cleaning, safe injection practices, and antimicrobial stewardship. It discusses the implementation challenges and solutions, such as ensuring compliance through education, monitoring and strong leadership. IPC measures are crucial in preventing infections such as catheter-associated urinary tract infections, central line-associated bloodstream infections, surgical site infections, and ventilator-associated pneumonia. By integrating personalised IPC strategies into nursing practice, healthcare providers can significantly improve infection control outcomes and enhance overall patient safety and quality of care.

Determinants of hand hygiene compliance among healthcare workers in intensive care units: a qualitative study.

BACKGROUND: Practicing hand hygiene is a cost-effective method to decrease the occurrence of Healthcare-Associated Infections (HAIs). However, despite their simplicity, adhering to hand hygiene methods among healthcare workers (HCWs) can be highly challenging. We aim to examine the factors influencing hand hygiene compliance as perceived by HCWs working in the intensive care units (ICUs) at several major hospitals in Riyadh, Saudi Arabia. METHOD: This qualitative study was conducted by adopting a content analysis to examine the interviews of HCWs who are currently working in the ICUs of various major hospitals located in the capital city of Riyadh, Saudi Arabia. RESULTS: We interviewed 49 HCWs working in ICUs, with an average age of 38 and 8 years of experience. The HCWs comprised doctors (n = 12), anesthesiologists (n = 6), and nurses (n = 31). There were 34 females and 15 males among the participants. Our analysis revealed several factors that impact hand hygiene compliance, including individual, work/environment, team, task, patient, organizational, and management concerns. Several obstacles and possibilities for enhancement have been identified. CONCLUSION: The results of this study would enhance our comprehension of hand hygiene practices and serve as a foundation for creating future strategies and assessment methods to enhance compliance with hand hygiene protocols in ICUs.

Reduction in diarrhea cases following implementation of COVID-19 hand hygiene interventions in Ghana: A causal impact analysis.

BACKGROUND: The human hand has constant contact with the environment, hence requires regular hand hygiene. Hand hygiene has gained recognition because of the COVID-19 pandemic and is a largely effective, affordable preventive measure against infectious diseases. This study used both national and sub-national analyses to evaluate the effect of COVID-19 handwashing guidelines on instances of diarrhea in Ghana. METHODS: Data on diarrhea cases spanning February 2018 and March 2022 were retrieved from the District Health Information Management System (DHIMS 2) using a data extraction guide. The data were summarized using descriptive statistics. The difference in diarrhea cases between the pre-COVID-19 and COVID-19 periods was measured using a two-sample t-test across Ghana's 16 administrative areas. Causal Impact package in R statistical software was employed to determine the impact of the introduction of COVID-19 hand hygiene protocols on diarrheal disease. RESULTS: A total of 5,645,533 diarrheal cases reported between February 2018 and March 2022 through the routine MIS (DHIMS2) were examined. Fifty-three percent of the cases occurred before the introduction of the hand hygiene protocol. Descriptive statistics indicated a statistically significant decrease in average diarrheal cases during the hand hygiene implementation era (13,463 cases reduction, p<0.001). Sub-national analyses revealed significant reductions in various regions: Greater Accra, Ashanti, Ahafo, Central, Eastern, Northern, Upper East, Upper West, and Volta (p<0.05). Causal impact analysis confirmed 11.0% nationwide reduction in diarrheal cases attributed to the COVID-19 hand hygiene protocols (p<0.001). CONCLUSION: This study underscores the effectiveness of COVID-19 hand hygiene protocols in reducing diarrheal morbidity in Ghana, with varying regional impacts. These findings advocate for the sustenance of investments and commitments made at the COVID hand hygiene protocols, particularly in this era where the pandemic appears controlled.

Barriers to Effective Infection Prevention in the Neonatal Intensive Care Unit: A Qualitative Study.

BACKGROUND: Infection prevention (IP) behaviors such as hand hygiene (HH) and mobile device disinfection are important to reduce the risk of infection transmission from both family members and hospital staff to critically ill neonates. PURPOSE: To inform the design of educational interventions to improve both patient family and staff IP behaviors, we engaged separate groups of nurses and family members to understand perceptions about the spread of infection and barriers to implementing effective IP strategies. METHODS: This was a qualitative study using focus groups to gather data from neonatal nurses and patient family members. Data were triangulated with hospital-wide survey data and analyzed using inductive content analysis. RESULTS: Twelve nurses and 4 patient family members participated. Themes related to communication about IP between staff and family members emerged: stakeholders expressed discomfort with the timing and nature of just-in-time HH education. These communication challenges contributed to stress levels within the neonatal intensive care unit. This finding was reflected in the hospital-wide survey. IMPLICATIONS FOR PRACTICE AND RESEARCH: Steps should be taken to improve communication about IP behaviors between patient family members and frontline staff. Reducing nurse burden of providing just-in-time HH reminders to patient family members through increased IP education may decrease stress and facilitate IP behaviors. This has the potential to decrease infection spread and improve patient outcomes. The development of interventions targeting stakeholder communication is therefore warranted, but additional research is needed to understand the timing and process for delivery of the educational material.

Predictors of hand hygiene attitudes among Saudi healthcare workers of the intensive care unit in Saudi Arabia.

Healthcare-associated infections present a challenge to healthcare systems, particularly critical care units. Hand hygiene emerges as a crucial element in infection control, acting as a vital link between healthcare workers, patients, and pathogens. Positive attitudes, motivated by a genuine concern for patient safety, are recognized as major predictors of hand hygiene compliance among healthcare workers. This study aims to assess the attitudes of ICU staff toward hand hygiene and identify factors that influence these attitudes. A cross-sectional survey of intensive care unit staff in seven large Saudi hospitals was conducted using an anonymous, self-reporting questionnaire to examine the attitudes of ICU personnel about hand hygiene and determine the factors that impact these attitudes. A regression analysis was used to determine the determinants of hand hygiene attitudes. Of the 600 respondents, 93% rated their hand hygiene knowledge as good, and 71% received hand hygiene training from their hospital. Most respondents (78%) had previously experienced healthcare-associated infections. The majority reported a favorable overall attitude toward hand hygiene (M = 4.15, SD = 0.85). Attitudes toward hand hygiene were significantly associated with perceived knowledge (ß = 0.32, p < 0.001), prior hand hygiene training (ß = 0.13, p < 0.05), and years of experience (ß = - 0.10, p < 0.05). Healthcare workers in the ICU have a generally positive attitude toward hand hygiene. Such attitudes were correlated with hand hygiene knowledge, prior training, and job experience. The study's findings can help to inform health promotion initiatives and campaigns aimed at achieving long-term improvements in hand hygiene behaviors.

Evaluating the tolerability and acceptability of a locally produced alcohol-based handrub and hand hygiene behaviour among health workers in Sierra Leone: a longitudinal hospital-based intervention study.

BACKGROUND: Alcohol-based handrub (ABHR) is the gold standard for hand hygiene (HH) and is a cornerstone of infection prevention and control (IPC) strategies. However, several factors influence the efficient use of ABHR by health workers. This study evaluated the tolerability and acceptability of a locally produced ABHR product and HH behaviour among health workers. METHODS: A longitudinal hospital-based intervention study was conducted in accordance with the WHO's standardized protocol for evaluating ABHR tolerability and acceptability (Method 1). Sixty health workers across 4 hospitals in Sierra Leone were observed over a 30-day period at three separate visits (days 1, 3-5, and 30) by trained observers. The outcomes of interest included skin tolerability and product acceptabilityevaluated using subjective and objective measures. RESULTS: Objective and subjective evaluations demonstrated strong skin tolerability and high acceptability with the product. At all three visits, the skin tolerability score assessed by trained observers was < 2 in ≥ 97% of participants, exceeding the WHO benchmark score (BMS = < 2 in ≥ 75%). Participants' self-evaluations of overall skin integrity were 97% (visit 2) and 98% (visit 3) for scores > 4 (BMS = > 4 in ≥ 75%). The primary acceptability criteria increased up to 95% (colour) and 88% (smell) at visit 3 (BMS = > 4 in ≥ 50%). Despite high acceptability, the product's drying effect remained low at 52% and 58% during visits 2 and 3, respectively (BMS = > 4 in ≥ 75%). There were positive HH behaviours (n = 53, 88%), with more than half (n = 38, 63%) of them exhibiting HH at almost every HH moment. The mean ABHR was notably high (76.1 ml, SD ± 35), especially among nurses (mean = 80.1 ml) and doctors (mean = 74.0 ml). CONCLUSION: The WHO-formulated, locally produced ABHR was well tolerated and accepted by health workers. These findings support the continuous utilization of evidence-based, cost-effective hand hygiene interventions in resource-limited settings. High handrub consumption and frequent HH practices were noticeable HH behaviours. Further research is recommended to optimize product formulations for skin dryness and investigate the association between ABHR consumption and hand hygiene compliance.

Dynamical analysis of methicillin-resistant Staphylococcus aureus infection in North Cyprus with optimal control: prevalence and awareness.

The number of Methicillin-resistant Staphylococcus aureus (MRSA) cases in communities and hospitals is on the rise worldwide. In this work, a nonlinear deterministic model for the dynamics of MRSA infection in society was developed to visualize the significance of awareness in interventions that could be applied in the prevention of transmission with and without optimal control. Positivity and uniqueness were verified for the proposed corruption model to identify the level of resolution of infection factors in society. Furthermore, how various parameters affect the reproductive number R 0 and sensitivity analysis of the proposed model was explored through mathematical techniques and figures. The global stability of model equilibria analysis was established by using Lyapunov functions with the first derivative test. A total of seven years of data gathered from a private hospital consisting of inpatients and outpatients of MRSA were used in this model for numerical simulations and for observing the dynamics of infection by using a non-standard finite difference (NSFD) scheme. When optimal control was applied as a second model, it was determined that increasing awareness of hand hygiene and wearing a mask were the key controlling measures to prevent the spread of community-acquired MRSA (CA-MRSA) and hospital-acquired MRSA (HA-MRSA). Lastly, it was concluded that both CA-MRSA and HA-MRSA cases are on the rise in the community, and increasing awareness concerning transmission is extremely significant in preventing further spread.

Microbiological safety assessment of restaurants and HACCP-certified kitchens in hotels: A study in eastern China.

The Hazard Analysis and Critical Control Point (HACCP) system plays a crucial role in ensuring food safety within food service establishments, effectively reducing the risk of foodborne diseases. This study focused on assessing the risk of microbe contamination in poultry-based cook-served food during meal preparation in four restaurants and five selected HACCP-certified hotels in eastern China. We examined samples collected from 26 poultry-based cooked dishes, 248 food contact surfaces, 252 non-food contact surfaces, and 121 hand swabs. Our findings indicated a favorable trend of compliance with Chinese national standards, as Escherichia coli and Campylobacter were not detected in any cooked food samples. However, the microbiological assessments revealed non-compliance with total plate count standards in 7 % of the cooked samples from restaurants. In contrast, both dine-in hotels and restaurants exhibited significant non-compliance with guidance concerning food and non-food contact surfaces. Furthermore, our study found that chefs' hand hygiene did not meet microbiological reference standards, even after washing. Notably, Campylobacter persisted at 27 % and 30 % on chefs' hands, posing a significant risk of cross-contamination and foodborne diseases. These findings emphasize the urgent necessity for enhanced supervision of hygiene procedures and process monitoring in the HACCP-certified establishments engaged in the preparation and serving of food. Targeted interventions and food safety education for different chef subgroups can enhance food handling practices and reduce the risk of foodborne diseases in independent food establishments.

The implications of healthcare professionals wearing jewelry on patient care biosafety: observational insights and experimental approaches.

The use of jewelry among healthcare professionals poses a risk of cross contamination due to potential bacterial accumulation and spread. Through a mixed-method design, this study first analyzed the implications of healthcare professionals wearing jewelry on patient care biosafety as well as on the residual bacterial load of hands and rings after hand hygiene. Firstly, an observational prevalence study to verify whether nursing professionals wear personal accessories during healthcare assistance was carried out. Second, an experimental design involving intentional contamination and hygiene of the hands, with and without a ring, was conducted. The bacterial load of both hands and rings was measured by counting colony forming units. The observational study showed that nursing workers frequently wear jewelry during healthcare assistance. Nonetheless, the experimental study did not indicate differences in bacterial contamination between hands with and without a ring, despite the hand hygiene procedure applied. In conclusion, many nursing workers wear jewelry in the workplace. Although hands with and without a ring exhibited similar microbial load, rings appeared as a potential source of bacterial contamination, reinforcing the need to remove jewelry during working hours. Hand hygiene using alcohol, or soap and water significantly decreased the bacterial load on the participants' hands, with handwashing proving to be the most efficient method for removing intentional contamination.

Viewpoint: The impending pandemic of resistant organisms - a paradigm shift towards source control is needed.

The United States needs a paradigm shift in its approach to control infectious diseases. Current recommendations are often made in a siloed feedback loop. This may be the driver for such actions as the abandonment of contact precautions in some settings, the allowance of nursing home residents who are carriers of known pathogens to mingle with others in their facility, and the determination of an intervention's feasibility based upon budgetary rather than health considerations for patients and staff. Data from both the U.S. Veterans Health Administration and the U.K.'s National Health Service support the importance of carrier identification and source control. Both organizations observed marked decreases in methicillin-resistant Staphylococcus aureus (MRSA), but not methicillin-susceptible Staphylococcus aureus infections with the implementation of MRSA admission screening measures. Facilities are becoming over-reliant on horizontal prevention strategies, such as hand hygiene and chlorhexidine bathing. Hand hygiene is an essential practice, but the goal should be to minimize the risk of workers' hands becoming contaminated with defined pathogens, and there are conflicting data on the efficacy of chlorhexidine bathing in non-ICU settings. Preemptive identification of dedicated pathogens and effective source control are needed. We propose that the Centers for Disease Control and Prevention should gather and publicly report the community incidence of dedicated pathogens. This will enable proactive rather than reactive strategies. In the future, determination of a patient's microbiome may become standard, but until then we propose that we should have knowledge of the main pathogens that they are carrying.

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

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