Rate of nosocomial MRSA transmission evaluated via contact screening.

BACKGROUND: The prevention of methicillin-resistant S. aureus (MRSA) transmission in the healthcare setting is a priority in Infection Control practices. A cornerstone of this policy is contact tracing of nosocomial contacts after an unexpected MRSA finding. The objective of this retrospective study was to quantify the rates of MRSA transmission in different clinical settings. METHODS: This multi-centre study included MRSA contact screening results from two regional hospitals and one academic hospital. MRSA contact tracing investigations from 2000 until 2019 were reviewed and post-contact screening results were included of index patients with an MRSA-positive culture and their unprotected contacts. Available typing results were used to rule out incidental findings. RESULTS: Of 27,377 contacts screened after MRSA exposure, 21,488 were Health Care Workers (HCW) and 4816 patients. Post-contact screening was initiated for a total of 774 index cases, the average number of screened contacts per index case was 35.7 (range 1 to 640). MRSA transmission was observed in 0.15% (41) of the contacts, 19 (0.09%) HCW and 22 (0.46%) patients. The number needed to screen to detect one MRSA transmission was 667. The highest risk of MRSA transmission occurred during patient-to-patient contacts, with transmission rates varying from 0.32 to 1.32% among the participating hospitals. No transmissions were detected in HCW (n=2834) in the outpatient setting, and the rate of transmissions among HCW contacts on the wards was 0.13% (19 of 15,874). Among 344 contacts of patients with contact precautions, no transmissions were detected. CONCLUSIONS: Reconsidering current MRSA contact tracing practices may lead to a more targeted approach with a lower number needed to screen.

Global Dynamics of Gastrointestinal Colonisations and Antimicrobial Resistance: Insights from International Travellers to Low- and Middle-Income Countries.

Gastrointestinal microorganism resistance and dissemination are increasing, partly due to international travel. This study investigated gastrointestinal colonisations and the acquisition of antimicrobial resistance (AMR) genes among international travellers moving between Spain and low- and middle-income countries (Peru and Ethiopia). We analysed 102 stool samples from 51 volunteers collected before and after travel, revealing significantly higher rates of colonisation by both bacteria and protists upon return. Diarrhoeagenic strains of E. coli were the most notable microorganism detected using RT-PCR with the Seegene Allplex™ Gastrointestinal Panel Assays. A striking prevalence of ß-lactamase resistance genes, particularly the TEM gene, was observed both before and after travel. No significant differences in AMR genes were found between the different locations. These findings highlight the need for rigorous surveillance and preventive strategies, as travel does not significantly impact AMR gene acquisition but does affect microbial colonisations. This study provides valuable insights into the intersection of gastrointestinal microorganism acquisition and AMR in international travellers, underscoring the need for targeted interventions and increased awareness.

Environmental Infrastructure Maintenance Bottlenecks in Healthcare Facilities and Coping Strategies Among Healthcare Workers in Niger.

Infrastructure for water, sanitation, hygiene, cleaning, and waste management is essential for supporting safe environmental conditions in healthcare facilities. Routine maintenance is important for preventing infrastructure breakdowns, but few studies have examined healthcare facility maintenance practices. This study documented environmental maintenance tasks in healthcare facilities in Niger, described bottlenecks to maintenance, and assessed strategies for coping with breakdowns. At 34 rural healthcare facilities in Niger, we conducted quantitative surveys to assess frequency of maintenance tasks and held qualitative interviews with healthcare facility staff to understand bottlenecks to maintenance. On at least a monthly basis, 4% of healthcare facilities inspected their water source and pump for the purpose of detecting and replacing worn parts, 15% inspected water taps and basins, and 29% inspected incinerators. Healthcare facility staff described barriers to accessing government funds for maintenance. Instead, they paid out of their own salaries or raised funds through appeals to community members or revenue generation initiatives. Other bottlenecks included ill-defined management responsibilities and difficulty of finding skilled technicians for maintenance. Findings highlight opportunities to support healthcare facilities in budgeting, advocacy, and training skilled technicians. Initiatives to install infrastructure at healthcare facilities will be more sustainable if they are accompanied by postconstruction planning, training, and funding for maintenance.

Implementation of COVID-19 infection control best practices in nursing homes amid the pandemic.

BACKGROUND: The COVID-19 pandemic has claimed around 170,000 lives among nursing home residents and staff in the United States through April 2023. In a cluster randomized controlled trial (RCT) with 136 nursing homes, we delivered training to improve COVID-19 infection control best practices. We sought to assess the implementation of infection control practices in participating nursing homes. METHODS: Concurrent with the delivery of the RCT (January-November 2021), we surveyed nursing home administrators (NHAs, n = 38) at baseline and 6-month follow-up. Using validated items from the Centers for Disease Control and Prevention (CDC), the surveys inquired about 80 infection control best-practice activities (yes/no). The survey also asked seven scales corresponding to inner setting factors that may have impacted implementation. We assessed changes in infection control practices and inner setting factors between baseline and 6-month follow-up. RESULTS: Overall, the implementation of 11 best practices changed over time. NHAs reported an increase in the availability of informational materials for residents and families (84% vs. 100%, p = 0.031), the use of alcohol-based hand sanitizer over soap (76% vs. 97%, p = 0.008), and the development of contingency plans for increased postmortem care (53% vs. 82%, p = 0.013). The implementation of four best-practice visitation policies and three communal restrictions decreased between baseline and 6-month follow-up (all p < 0.05). Regarding inner setting factors, only culture stress (perceived strain, stress, and role overload) increased between surveys (mean scores: 3.14 vs. 3.58, p = 0.004). CONCLUSION: This study was among the first to report changes in implementing COVID-19 infection control best practices in nursing homes amid the pandemic. Culture stress was an important inner setting factor that may have impacted implementation activities. TRIAL REGISTRATION: NCT04499391 DATE OF REGISTRATION: August 3rd, 2020.

The effectiveness of interventions to reduce the transmission of acute respiratory infections in care homes: a systematic review.

BACKGROUND: Care home residents are at high risk from outbreaks of respiratory infections, such as influenza and COVID-19. We conducted a systematic review of randomized controlled trials, to determine which interventions (apart from vaccines) are effective at reducing transmission of acute respiratory illnesses (ARIs) in care homes. METHODS: We searched CINAHL, Medline, Embase and Cochrane for randomized controlled trials (RCTs) of interventions to prevent transmission of ARIs in care homes (excluding vaccines), to April 2023. RESULTS: A total of 21 articles met inclusion criteria. Two infection control interventions significantly reduced respiratory infections. Oseltamivir significantly reduced risk of symptomatic laboratory-confirmed influenza (OR 0.39, 95%CI 0.16-0.94, three trials), and influenza-like illness (OR 0.50, 95%CI 0.36-0.69), even in a vaccinated population. High dose vitamin D supplementation reduced incidence of ARIs (incidence rate ratio 0.60; 95%CI 0.38-0.94, one trial). Nine other RCTs of vitamin, mineral, probiotic and herbal supplements showed no significant effect. CONCLUSION: Transmission of respiratory infections in care homes can be reduced by educational interventions to improve infection control procedures and compliance by staff, by antiviral prophylaxis soon after a case of influenza has been detected, and by supplementation with high-dose Vitamin D3. Further research is needed to confirm the effect of high-dose Vitamin D3.

Factors Associated with Poor Clinical and Microbiologic Outcomes in C. auris Bloodstream Infection: A Multicenter Retrospective Cohort Study.

BACKGROUND: C. auris has become a growing concern worldwide due to increases in incidence of colonization and reports of invasive infections. There are limited data on clinical factors associated with poor outcomes in patients with C. auris bloodstream infection (BSI). METHODS: We assembled a multicenter retrospective cohort of patients with C. auris BSI from two geographics areas in US healthcare settings. We collected data on demographic, clinical, and microbiologic characteristics to describe the cohort and constructed multivariate logistic regression models to understand risk factors for two clinical outcomes, all-cause mortality during facility admission, and blood culture clearance. RESULTS: Our cohort consisted of 187 patients with C. auris BSI (56.1% male, 55.6% age >65 years); 54.6% died by facility discharge and 66.9% (of 142 with available data) experienced blood culture clearance. Pitt bacteremia score at infection onset was associated with mortality (odds-ratio [95% confidence interval]: 1.19 [1.01,1.40] per 1-point increase). Hemodialysis was associated with a reduced odds of microbiologic clearance (0.15 [0.05,0.43]) and with mortality (3.08 [1.27,7.50]). CONCLUSIONS: The Pitt bacteremia score at the onset of C. auris BSI may be a useful tool in identifying patients at risk for mortality. Targeted infection prevention practices in patients receiving hemodialysis may be useful to limit poor outcomes.

Vaccines and monoclonal antibodies to prevent healthcare-associated bacterial infections.

SUMMARYHealthcare-associated infections (HAIs) represent a burden for public health with a high prevalence and high death rates associated with them. Pathogens with a high potential for antimicrobial resistance, such as ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species) and Clostridioides difficile, are responsible for most HAIs. Despite the implementation of infection prevention and control intervention, globally, HAIs prevalence is stable and they are mainly due to endogenous pathogens. It is undeniable that complementary to infection prevention and control measures, prophylactic approaches by active or passive immunization are needed. Specific groups at-risk (elderly people, chronic condition as immunocompromised) and also healthcare workers are key targets. Medical procedures and specific interventions are known to be at risk of HAIs, in addition to hospital environmental exposure. Vaccines or monoclonal antibodies can be seen as attractive preventive approaches for HAIs. In this review, we present an overview of the vaccines and monoclonal antibodies in clinical development for prevention of the major bacterial HAIs pathogens. Based on the current state of knowledge, we look at the challenges and future perspectives to improve prevention by these means.

A time-motion study on impact of spatial separation for empiric airborne precautions in emergency department length of stay.

AIMS: To evaluate the impact of spatial separation on patient flow in the emergency department. DESIGN: This was a retrospective, time-and-motion analysis conducted from 15 to 22 August, 2022 at the emergency department of a tertiary hospital in Kuala Lumpur, Malaysia. During this duration, spatial separation was implemented in critical and semi-critical zones to separate patients with symptoms of respiratory infections into respiratory area, and patients without into non-respiratory area. This study adhered to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. METHODS: Patients triaged to critical and semi-critical zones were included in this study. Timestamps of patient processes in emergency department until patient departure were documented. RESULTS: The emergency department length-of-stay was longer in respiratory area compared to non-respiratory area; 527 min (381-698) versus 390 min (285-595) in critical zone and 477 min (312-739) versus 393 min (264-595) in semi-critical zone. In critical zone, time intervals of critical flow processes and compliance to hospital benchmarks were similar in both areas. More patients in respiratory area were managed within the arrival-to-contact ≤30 min benchmark and more patients in non-respiratory area had emergency department length-of-stay ≤8 h. CONCLUSIONS: The implementation of spatial separation in infection control should address decision-to-departure delays to minimise emergency department length of stay. IMPACT: The study evaluated the impact of spatial separation on patient flow in the emergency department. Emergency department length-of-stay was significantly prolonged in the respiratory area. Hospital administrators and policymakers can optimise infection control protocols measures in emergency departments, balancing infection control measures with efficient patient care delivery. REPORTING METHOD: STROBE guidelines. NO PATIENT OR PUBLIC CONTRIBUTION: None. TRIAL AND PROTOCOL REGISTRATION: The study obtained ethics approval from the institution's Medical Ethics Committee (MREC ID NO: 20221113-11727). STATISTICAL ANALYSIS: The author has checked and make sure our submission has conformed to the Journal's statistical guideline. There is a statistician on the author team (Noor Azhar).

Association between Hand Hygiene Knowledge and Self-Efficacy in Nursing Students: A Multicenter Cross-Sectional Study within the Framework of the Erasmus Project.

Adherence to hand hygiene procedures is crucial for all populations, and the World Health Organization (WHO) has implemented specific guidelines for infection control. Frequent and correct hand hygiene can prevent infections, but non-compliance with hand hygiene is pervasive. Nursing students address this issue from the beginning of their training. In nursing training, self-efficacy is crucial in enhancing students' competence, motivation, and clinical performance. We performed a cross-sectional multicenter study in five European countries, with a cross-sectional design with an online application of an instrument measuring hand hygiene knowledge based on WHO guidelines and general self-efficacy and specific self-efficacy for infection control. A total of 638 first-year nursing students participated in this study. The mean percentage of correct answers was 67.9%, with a considerable difference depending on the items. The worst results were obtained for questions related to sources of infection and types of hand hygiene methods in different situations. Finnish students displayed significantly (p < 0.001) higher scores in HH knowledge, whereas Estonian students had significantly (p < 0.001) higher levels of self-efficacy. There were significant correlations between the hand hygiene knowledge score and the self-efficacy score (p < 0.001). A multivariate analysis by linear regression analysis showed significant associations between the hand hygiene knowledge survey score and the students' age (p < 0.001, OR = 0.18, 95% CI 0.04-0.10), as well as their country of origin (p = 0.01, OR = 0.09, 95% CI 0.03-0.34). HH knowledge is quite low among nursing students, and is correlated with self-efficacy, although the strongest predictors are age and country of origin. Different nursing curricula must favor HH knowledge, with varying degrees of emphasis depending on the country.

Preventing urinary tract infection in older people living in care homes: the 'StOP UTI' realist synthesis.

BACKGROUND: Urinary tract infection (UTI) is the most diagnosed infection in older people living in care homes. OBJECTIVE: To identify interventions for recognising and preventing UTI in older people living in care homes in the UK and explain the mechanisms by which they work, for whom and under what circumstances. METHODS: A realist synthesis of evidence was undertaken to develop programme theory underlying strategies to recognise and prevent UTI. A generic topic-based search of bibliographic databases was completed with further purposive searches to test and refine the programme theory in consultation with stakeholders. RESULTS: 56 articles were included in the review. Nine context-mechanism-outcome configurations were developed and arranged across three theory areas: (1) Strategies to support accurate recognition of UTI, (2) care strategies for residents to prevent UTI and (3) making best practice happen. Our programme theory explains how care staff can be enabled to recognise and prevent UTI when this is incorporated into care routines and activities that meet the fundamental care needs and preferences of residents. This is facilitated through active and visible leadership by care home managers and education that is contextualised to the work and role of care staff. CONCLUSIONS: Care home staff have a vital role in preventing and recognising UTI in care home residents.Incorporating this into the fundamental care they provide can help them to adopt a proactive approach to preventing infection and avoiding unnecessary antibiotic use. This requires a context of care with a culture of personalisation and safety, promoted by commissioners, regulators and providers, where leadership and resources are committed to support preventative action by knowledgeable care staff.

Effects of stress on burnout among infection control nurses during the COVID-19 pandemic: the mediating effects of social support and self-efficacy.

BACKGROUND: This study investigated the mediating effects of self-efficacy and social support on the relationship between stress and burnout among infection control nurses (ICNs) during an emerging infectious disease pandemic. METHODS: The study participants encompassed 210 ICNs with at least six months' experience in an infection control unit at a general hospital in South Korea during the COVID-19 pandemic. Data were analyzed using independent t-tests or one-way analysis of variance (ANOVA), while descriptive statistics were performed using SPSS/WIN 26.0 software. Hayes's PROCESS macro 4.2 software was used to verify the significance of the indirect effects of the mediators. RESULTS: Stress had a significant positive effect on burnout (ß = 0.80, p < .001), accounting for 73% of the variance. Self-efficacy (ß = - 0.26, p < .001) and social support (ß = - 0.11, p = .034) had a significant negative effect on burnout, accounting for 78% of the variance. Stress was lower when self-efficacy and social support were entered into the model (ß = 0.80 → 0.59), indicating that self-efficacy and social support mediated the relationship between stress and burnout. CONCLUSION: This study is significant in that it confirms the effects of self-efficacy and social support on the relationship between stress and burnout among ICNs. The results highlight the importance of establishing organizational support systems and developing and implementing programs for enhancing self-efficacy in order to reduce burnout among ICNs.

Feasibility, efficacy, and safety of animal-assisted activities with visiting dogs in inpatient pediatric oncology.

BACKGROUND: Childhood cancer entails a heavy burden for patients and their families. Recent advances in overall survival rates have increasingly brought long-term quality of life into focus. Animal-assisted activities (AAAs) have long been hypothesized to alleviate the burden on pediatric patients and their peers in the hospital setting. However, their use in inpatient pediatric oncology has been a sensitive issue mainly due to the fear of infections, resulting in a lack of studies. This study presents data on the feasibility, safety, and efficacy of AAAs from a single German center. METHODS: Between 2018 and 2022, 60 patients (median age = 10.3 years) diagnosed with malignancy and undergoing treatment were visited by an intervention dog (total visits = 100). Patients were screened for infections as per hospital policy, with additional microbiological testing performed based on symptoms. The dog was screened for human pathogens and zoonoses. Microbial data and hospitalizations were analyzed from two months prior to the first visit until two months after the last visit. Acceptance of being in the hospital, both with and without planned animal-assisted interventions and pre- and post-intervention state stress, were measured using a validated visual analogue scale (0-10). RESULTS: Patients benefited from AAAs, showing increased acceptance of being in the hospital (median: 7.25 vs. 4.50, P < 0.001) and decreased median state stress ratings one hour after the visit compared to one hour before the visit (1.00 vs. 4.25, P < 0.001). The intervention did not result in an increased number of infections or unplanned hospitalizations, and no zoonoses were detected. All microbial screening tests of the dog were negative. CONCLUSIONS: AAAs with visiting dogs in inpatient pediatric oncology are feasible and safe. Although they hold promise for enhancing patients' well-being, further prospective studies are needed.

Epidemiological and environmental investigation of the 'big four' Vibrio species, 1994 to 2021: a Baltic Sea retrospective study.

BackgroundThe Vibrio genus comprises several bacterial species present in the Baltic Sea region (BSR), which are known to cause human infections.AimTo provide a comprehensive retrospective analysis of Vibrio-induced infections in the BSR from 1994 to 2021, focusing on the 'big four' Vibrio species - V. alginolyticus, V. cholerae non-O1/O139, V. parahaemolyticus and V. vulnificus - in eight European countries (Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland and Sweden) bordering the Baltic Sea.MethodsOur analysis includes data on infections, Vibrio species distribution in coastal waters and environmental data received from national health agencies or extracted from scientific literature and online databases. A redundancy analysis was performed to determine the potential impact of several independent variables, such as sea surface temperature, salinity, the number of designated coastal beaches and year, on the Vibrio infection rate.ResultsFor BSR countries conducting surveillance, we observed an exponential increase in total Vibrio infections (n = 1,553) across the region over time. In Sweden and Germany, total numbers of Vibrio spp. and infections caused by V. alginolyticus and V. parahaemolyticus positively correlate with increasing sea surface temperature. Salinity emerged as a critical driver of Vibrio spp. distribution and abundance. Furthermore, our proposed statistical model reveals 12 to 20 unreported cases in Lithuania and Poland, respectively, countries with no surveillance.ConclusionsThere are discrepancies in Vibrio surveillance and monitoring among countries, emphasising the need for comprehensive monitoring programmes of these pathogens to protect human health, particularly in the context of climate change.

Infection prevention and control: understanding the fundamentals.

Infection prevention and control is crucial to prevent patients and healthcare staff from being harmed by avoidable infections, including healthcare-associated infections. This article outlines the main elements of standard precautions for infection prevention and control, as set out by the World Health Organization. Nurses and other healthcare professionals can use this information to refresh their knowledge of infection prevention and control, understand the appropriate practices that should be adopted to reduce the risk of infection transmission, and increase their awareness of the importance of sustainability and education.

Controlled Substance Liquid Waste Management Systems As Potential Reservoirs for Nosocomial Infection in a Pediatric Hospital.

OBJECTIVE: The purpose of this study was to determine if controlled substance waste management systems (CSWMS) demonstrate microbial growth, and therefore present a potential infection risk to pediatric hospital patients. METHODS: Twenty CSWMS, either Smart Sink or Pharma Lock systems, located in patient care areas were sampled. Twelve were located in critical care areas. Cultures were obtained by swabbing the drain grate with a sterile swab. Swabs were then transported to the microbiology lab for culture. Each sample was labeled with the location of the CSWMS and each system was photographed. RESULTS: Of the CSWMS sampled, 50% demonstrated bacterial or fungal growth with a total of 15 microorganisms isolated, including 3 systems with Micrococcus luteus, 2 with Aspergillus species, and 2 with -Bacillus cereus. Nine of the 15 microorganisms isolated were from systems in the pediatric intensive care unit (PICU) followed by 2 microorganisms in the neonatal intensive care unit (NICU). Of the 12 systems sampled in critical care areas, 8 (66%) had positive cultures. Of the 10 systems which demonstrated growth, 9 were Pharma Lock and 1 was Smart Sink. CONCLUSION: Controlled substance waste management systems harbor potential pathogens and may serve as reservoirs of infectious agents in pediatric hospitals. Microbial growth was identified in more than half of sampled CSWMS located in critical care areas, where the most vulnerable patients are located. Based on this study, a cleaning procedure for CSWMS should be implemented. Further investigation on the relationship between CSWMS and nosocomial infections is warranted.

Infection prevention and control in 2030: a first qualitative survey by the Crystal Ball Initiative.

BACKGROUND: Healthcare delivery is undergoing radical changes that influence effective infection prevention and control (IPC). Futures research (short: Futures), the science of deliberating on multiple potential future states, is increasingly employed in many core societal fields. Futures might also be helpful in IPC to facilitate current education and organisational decisions. Hence, we conducted an initial survey as part of the IPC Crystal Ball Initiative. METHODS: In 2019, international IPC experts were invited to answer a 10-item online questionnaire, including demographics, housekeeping, and open-ended core questions (Q) on the "status of IPC in 2030" (Q1), "people in charge of IPC" (Q2), "necessary skills in IPC" (Q3), and "burning research questions" (Q4). The four core questions were submitted to a three-step inductive and deductive qualitative content analysis. A subsequent cross-case matrix produced overarching leitmotifs. Q1 statements were additionally coded for sentiment analysis (positive, neutral, or negative). RESULTS: Overall, 18 of 44 (41%) invited experts responded (from 11 countries; 12 physicians, four nurses, one manager, one microbiologist; all of them in senior positions). The emerging leitmotifs were "System integration", "Beyond the hospital", "Behaviour change and implementation", "Automation and digitalisation", and "Anticipated scientific progress and innovation". The statements reflected an optimistic outlook in 66% of all codes of Q1. CONCLUSIONS: The first exercise of the IPC Crystal Ball Initiative reflected an optimistic outlook on IPC in 2030, and participants envisioned leveraging technological and medical progress to increase IPC effectiveness, freeing IPC personnel from administrative tasks to be more present at the point of care and increasing IPC integration and expansion through the application of a broad range of skills. Enhancing participant immersion in future Crystal Ball Initiative exercises through simulation would likely further increase the authenticity and comprehensiveness of the envisioned futures.

A questionnaire survey of infection control measures during the coronavirus infectious disease 2019 pandemic era.

OBJECTIVE: To clarify the infection control measures required in the event of a new infectious disease outbreak, we conducted a questionnaire survey on the infection control measures implemented against coronavirus disease 2019 (COVID-19). METHODS: An invitation to participate in this survey was sent to the heads of 2689 facilities affiliated with the members of the Japanese Society for Infection Prevention and Control in February 2023, requesting responses to the online survey using Google Forms by March 2023. RESULTS: Six hundred and forty-five facilities, including 20 clinics and 625 hospitals, participated in the survey. This survey revealed that various infection control measures were implemented, including universal masking in the non-COVID-19 ward (96.5 %), screening tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on scheduled admission (89.0 %), SARS-CoV-2 tests (98.7 %), and isolation in private rooms (76.5 %) for inpatients with fever. However, nosocomial infections and clusters of COVID-19 occurred in 94.4 % and 90.9 % of cases during the investigation period, respectively. One of the reasons for these results is that healthcare personnel (HCP) and patients were common index cases of nosocomial infections, and the most common cause of clusters was the work of symptomatic HCPs. These results suggest that HCPs should understand that they can be index cases or spreaders. On the other hand, the most common support from external facilities was healthcare centers, followed by physicians or nurses from other hospitals. CONCLUSION: In response to the emergence of infections, it is important to consider implementing infection control measures for HCPs and patients.

Emergency infection prevention and control training in fragile, conflict-affected or vulnerable settings: a scoping review.

BACKGROUND: It is uncertain what could be the best training methods for infection prevention and control when an infectious disease threat is active or imminent in especially vulnerable or resource-scarce settings. METHODS: A scoping review was undertaken to find and summarise relevant information about training modalities, replicability and effectiveness of IPC training programmes for clinical staff as reported in multiple study designs. Eligible settings were conflict-affected or in countries classified as low-income or lower-middle income (World Bank 2022 classifications). Search terms for LILACS and Scopus were developed with input of an expert working group. Initially found articles were dual-screened independently, data were extracted especially about infection threat, training outcomes, needs assessment and teaching modalities. Backwards and forwards citation searches were done to find additional studies. Narrative summary describes outcomes and aspects of the training programmes. A customised quality assessment tool was developed to describe whether each study could be informative for developing specific future training programmes in relevant vulnerable settings, based on six questions about replicability and eight questions about other biases. FINDINGS: Included studies numbered 29, almost all (n = 27) were pre-post design, two were trials. Information within the included studies to enable replicability was low (average score 3.7/6). Nearly all studies reported significant improvement in outcomes suggesting that the predominant study design (pre-post) is inadequate to assess improvement with low bias, that any and all such training is beneficial, or that publication bias prevented reporting of less successful interventions and thus a informative overview. CONCLUSION: It seems likely that many possible training formats and methods can lead to improved worker knowledge, skills and / or practice in infection prevention and control. Definitive evidence in favour of any specific training format or method is hard to demonstrate due to incomplete descriptions, lack of documentation about unsuccessful training, and few least-biased study designs (experimental trials). Our results suggest that there is a significant opportunity to design experiments that could give insights in favour of or against specific training methods. "Sleeping" protocols for randomised controlled trials could be developed and then applied quickly when relevant future events arise, with evaluation for outcomes such as knowledge, practices, skills, confidence, and awareness.

Middle East Respiratory Syndrome Coronavirus Could be a Priority Pathogen to Cause Public Health Emergency: Noticeable Features and Counteractive Measures.

Middle East respiratory syndrome (MERS) is caused by a specific strain of the 6 types of human coronaviruses (HCoV). MERS-CoV has spread unchecked since it was first discovered in Saudi Arabia in 2012. The virus most likely spreads through nosocomial and zoonotic channels. Genetic analyses suggest that bats were the initial hosts and that the disease spread to camels. Person-to-person transmission occurs with varying frequency, being most prevalent in clinical settings and the least common among the general population and among close relatives. Due to the severity of the illness, high fatality rate, potential for epidemic spread, and lack of adequate medical countermeasures, the World Health Organization (WHO) continues to list MERS-CoV as a priority pathogen. While no specific antiviral medicines exist, a combination of antivirals has shown promise in recent clinical trials. Vaccines against MERS-CoV are critically needed and are currently being developed. Early diagnosis and implementing appropriate infection control measures are keys to preventing hospital-associated outbreaks. Preventive measures include avoiding raw or undercooked meats and other animal products, ensuring proper hand hygiene in healthcare settings and around dromedaries, educating the public and healthcare personnel about the disease, and adhering to other recommended practices. Countries with a high prevalence of MERS should adhere to regulations designed to limit the transmission of the virus. The recent spread of MERS-CoV highlights the importance of public awareness regarding the significance of reporting symptoms so that appropriate control measures can be adopted. The narrative review discusses the incidence of MERS, its clinical presentation, potential transmission routes, recent reports, preventative and control measures, and current therapeutic options.
