Assessment Of Knowledge Attitude And Practices Of Operation Theatre Staff Regarding Prevention Of Catheter Associated Urinary Tract Infection

Objective: to evaluate the knowledge, attitudes, and practices of operating theatre staff concerning CAUTI prevention at Health Sciences, Superior University, Lahore, Pakistan. Study Design: A Cross sectional Study Place and Duration of the Study: A cross-sectional study was performed with operating theater personnel, comprising physicians, nurses, and technicians, at Health Sciences, Superior University, Lahore. Methodology: A standardized questionnaire was employed to assess participants' understanding of CAUTI causes, dangers, and preventative measures; attitudes towards CAUTI prevention; and compliance with suggested actions. Data were gathered and examined to pinpoint knowledge deficiencies and intervention opportunities. Results: The study measured the knowledge, attitude, and practices (KAP) of operating room staff with relation to preventing catheter-associated urinary tract infections (CAUTIs). The results showed that, on average, 1.8 out of a possible 5.0 points were deemed sufficient, and that 52.7% shown moderately adequate knowledge. A mean attitude score of 2.05 (SD = 0.75) was produced by the mixed attitudes, with 40.9% exhibiting somewhat positive attitudes and 29.1% indicating favorable attitudes. The staff's level of practice adherence varied; on average, 1.88 (SD=0.6), with 56.4% indicating moderate practice and 43.6% indicating adequate practice. Staff members acknowledged the significance of aseptic technique to a degree of 94.5%, and 79.1% were in favor of prompt catheter removal to avoid CAUTI, according to key responses. Higher levels of practice adherence were linked to more professional experience (χ² = 19.172, p < 0.01), and there were notable positive associations between attitude and practice (rho = 0.264, p < 0.01). Despite a moderate degree of knowledge and practice, patient safety can only be improved by targeted education that fills attitude gaps and enhances CAUTI prevention strategies. Conclusion: CAUTI is a common healthcare-associated disease. Healthcare personnel had sufficient CAUTI prevention knowledge, attitudes, and practices in this study. Every hospital's infection prevention program must create, implement, and monitor urinary catheter infection prevention policies. Health care organizations must establish medical education programs, interdisciplinary training, and catheter care checklist audits to improve staff knowledge and practices.

The impact of statewide educational webinars on infection prevention and control knowledge and policy updates in acute and long-term care facilities during the COVID-19 pandemic: the Nebraska experience.

A Nebraska statewide webinar series was initiated during the coronavirus disease 2019 (COVID-19) pandemic for long-term care (LTC) and acute care/outpatient (AC) facilities. An impact survey was completed by 48 of 96 AC and 109 of 429 LTC facilities. The majority reported increased regulatory awareness (AC: 65%, LTC: 54%) and updated COVID-19 (AC: 61%, LTC: 69%) and general infection prevention (AC: 61%, LTC: 60%) policies.

Epidemiologic characteristics of people living with human immunodeficiency virus in South Korea: a nationwide cohort study

Recent information regarding the characteristics of people living with human immunodeficiency virus (HIV) (PLWH) is lacking. Therefore, we examined the incidence of HIV infection and epidemiologic characteristics of PLWH in South Korea using recent National Health Insurance Service database data. The HIV infection rate was 4.13 per 100,000 in 2017, 4.19 per 100,000 in 2018, 6.61 per 100,000 in 2019, 5.98 per 100,000 in 2020, 8.81 per 100,000 in 2021, and 4.14 per 100,000 in 2022. In 2016, the mean age of PLWH was 45.7 years (SD: 13.8 years), and it gradually increased to 49.0 years (standard deviation: 13.7 years) in 2022 over 7 years in South Korea. The proportion of male individuals among PLWH was 90.7% (19,970/22,026) in 2016, and it gradually increased to 92.3% (22,943/24,857) in 2022 over 7 years in South Korea. The proportion of anti-retroviral therapy (ART) users among PLWH in South Korea was 92.6% (20,388/22,026) in 2016, and it gradually increased to 97.9% (24,328/24,857) in 2022 over 7 years. In this population-based cohort analysis, we presented the HIV infection incidence and epidemiologic features of PLWH in South Korea. This study’s results may influence future infection prevention strategies and policies for PLWH.

Desiccation tolerance and reduced antibiotic resistance: Key drivers in ST239-III to ST22-IV MRSA clonal replacement at a Malaysian teaching hospital

Molecular surveillance of methicillin-resistant Staphylococcus aureus (MRSA) isolated from Hospital Canselor Tuanku Muhriz (HCTM), a Malaysian teaching hospital revealed clonal replacement events of SCCmec type III-SCCmercury to SCCmec type IV strains before the year 2017; however, the reasons behind this phenomenon are still unclear. This study aimed to identify factors associated with the clonal replacement using genomic sequencing and phenotypic investigations (antibiogram profiling, growth rate and desiccation tolerance determination, survival in vancomycin sub-minimum inhibitory concentration (MIC) determination) of representative HCTM MRSA strains isolated in four-year intervals from 2005 – 2017 (n = 16). HCTM Antimicrobial Stewardship (AMS) and Infection Prevention and Control (IPC) policies were also reviewed. Phylogenetic analyses revealed the presence of 3 major MRSA lineages: ST239-III, ST22-IV and ST6-IV; MRSAs with the same STs shared similar core and accessory genomes. Majority of the ST239-III strains isolated in earlier years of the surveillance (2005, 2009 and 2013) were resistant to many antibiotics and harboured multiple AMR and virulence genes compared to ST22-IV and ST6-IV strains (isolated in 2013 and 2017). Interestingly, ST22-IV and ST6-IV MRSAs grew significantly faster and were more resistant to desiccation than ST239-III (p < 0.05), even though the later clone survived better post-vancomycin exposure. Intriguingly, ST22-IV was outcompeted by ST239-III in broth co-cultures; though it survived better when desiccated together with ST239-III. Higher desiccation tolerance and fewer carriage of AMR genes by ST22-IV, together with reduction of antibiotic selection pressure in HCTM (due to AMS and IPC policies) during 2005 – 2017 may have provided the clone a competitive edge in replacing the previously dominant ST239-III in HCTM. This study highlights the importance of MRSA surveillance for a clearer picture of circulating clones and clonal changes. To our knowledge, this is the first genomic epidemiology study of MRSA in Malaysia, which will serve as baseline genomic data for future surveillance.

The State-of-the-Art of Mycobacterium chimaera Infections and the Causal Link with Health Settings: A Systematic Review.

(1) Background. A definition of healthcare-associated infections is essential also for the attribution of the restorative burden to healthcare facilities in case of harm and for clinical risk management strategies. Regarding M. chimaera infections, there remains several issues on the ecosystem and pathogenesis. We aim to review the scientific evidence on M. chimaera beyond cardiac surgery, and thus discuss its relationship with healthcare facilities. (2) Methods. A systematic review was conducted on PubMed and Web of Science on 7 May 2024 according to PRISMA 2020 guidelines for reporting systematic reviews, including databases searches with the keyword "Mycobacterium chimaera". Article screening was conducted by tree authors independently. The criterion for inclusion was cases that were not, or were improperly, consistent with the in-situ deposition of aerosolised M. chimaera. (3) Results. The search yielded 290 eligible articles. After screening, 34 articles (377 patients) were included. In five articles, patients had undergone cardiac surgery and showed musculoskeletal involvement or disseminated infection without cardiac manifestations. In 11 articles, respiratory specimen reanalyses showed M. chimaera. Moreover, 10 articles reported lung involvement, 1 reported meninges involvement, 1 reported skin involvement, 1 reported kidney involvement after transplantation, 1 reported tendon involvement, and 1 reported the involvement of a central venous catheter; 3 articles reported disseminated cases with one concomitant spinal osteomyelitis. (4) Conclusions. The scarce data on environmental prevalence, the recent studies on M. chimaera ecology, and the medicalised sample selection bias, as well as the infrequent use of robust ascertainment of sub-species, need to be weighed up. The in-house aerosolization, inhalation, and haematogenous spread deserve experimental study, as M. chimaera cardiac localisation could depend to transient bacteraemia. Each case deserves specific ascertainment before tracing back to the facility, even if M. chimaera represents a core area for healthcare facilities within a framework of infection prevention and control policies.

A survey of infection prevention and animal-assisted activity policies in health care facilities—United States, 2023

In a survey of 104 USinfectious disease specialists, 88% reported working in facilities that allow animal-assisted activities or pet visitation. Variability existed in the species of animals allowed, restricted areas, and veterinary assessments, demonstrating a need to standardize infection prevention approaches across health care facilities to mitigate potential risks.

Operating Room Airborne Microbial Load: Nonscrubbed Staff Apparel Matters

BackgroundInfection is a leading cause of total joint arthroplasty failure. In previous studies, we found correlations between the level of contamination, concentrations of airborne particles, and the number of staff present. In this study, we focused on the apparel of nonscrubbed operating room (OR) staff to elucidate their contribution to the airborne microbial load. MethodsWe compared hospital-laundered scrubs to disposable coveralls using 2 methods. (1) Participants entered an isolation chamber with a controlled environment and completed tasks for 1 hour wearing both the approved and alternative OR attire. Settle plates collected viable contaminants that were shed by the participants during testing. (2) Lab members conducted standardized maneuvers in a functional OR that simulated typical movements of the nurse, anesthesiologist, implant representative, and entering/exiting staff. An airborne particle counter and settle plates were positioned throughout the OR. After 1 hour, the staff changed apparel and repeated the test. Each session of both phases consisted of 2 tests by the same individuals on the same day. ResultsThere was approximately a 10-fold difference in the settlement rate of viable particles between groups when employing the isolation chamber. The settle rate for scrubs was 5,519 ± 1,381 colony forming units (CFUs)/m2/h, while the settle rate for coveralls was 505 ± 55 CFUs/m2/h (P = .008). During testing in the OR, 218.7 ± 35 CFUs/m2/h were captured for scrubs, compared with 50.5 ± 13 CFUs/m2/h for the coverall (P < .01). The concentration of airborne particles collected for scrubs was 4,952.1 ± 495 particles/m3 and 1,065 ± 53 particles/m3 for the coveralls (P < .01). This was a 77% and 79% reduction for both measures, respectively. ConclusionsThe open nature of standard scrubs allows contaminated particles to escape into the OR environment, whereas the one-piece design of the coveralls restricts pathways of escape. The results of this study may be helpful when developing hospital infection prevention policies.

Knowledge, Attitude and Practices (KAP) of Sterilization and Disinfection of Health Care Professionals in Bangladesh

&amp;lt;i&amp;gt;Background:&amp;lt;/i&amp;gt; Healthcare professionals face a constant risk of acquiring infections from patients. Exposure to blood, saliva, and sharp instruments increases their susceptibility to various infectious diseases. Proper sterilization and disinfection procedures are crucial for protecting both healthcare workers and patients. &amp;lt;i&amp;gt;Objective:&amp;lt;/i&amp;gt; This study aimed to assess the knowledge, attitude, and practices regarding sterilization and disinfection among healthcare professionals in Bangladesh.&amp;lt;i&amp;gt; Methods&amp;lt;/i&amp;gt;: A cross-sectional study was conducted at the National Institute of Cardiovascular Diseases &amp; Hospital in Dhaka, Bangladesh, from January to June 2023. A total of 81 healthcare professionals were randomly selected and participated in the study after providing verbal consent. Data collection involved a pre-structured questionnaire focusing on knowledge, attitude, and practices related to sterilization and disinfection. Statistical analysis was performed using SPSS software, and results were presented as frequencies and percentages. Ethical clearance was obtained before the study commenced. &amp;lt;i&amp;gt;Results: &amp;lt;/i&amp;gt;The study included healthcare professionals from various backgrounds, with the majority being young adults (21-25 years old). Knowledge assessment revealed a good understanding of sterilization methods, disinfection procedures, post-sterilization instrument management, and waste disposal practices. Additionally, most participants were aware of the hospital&amp;apos;s sterilization protocols and infection prevention policies. Regarding attitudes, a positive response was observed towards regular training for staff, proper use of personal protective equipment (PPE), and adherence to sterilization and disinfection guidelines. However, a minority expressed concerns about reusing disposable items. Practices reflected the positive knowledge and attitudes, with a high percentage of participants following hand hygiene protocols, using PPE, and opting for disposable equipment. However, a small number reported experiencing needle-stick injuries, highlighting a potential gap between knowledge and practice. &amp;lt;i&amp;gt;Conclusions:&amp;lt;/i&amp;gt; the study found that a majority of healthcare professionals in this setting demonstrated good knowledge, positive attitudes, and appropriate practices regarding sterilization and disinfection. However, a small knowledge, attitude, and practice gap was identified, particularly concerning needle-stick injuries. These findings suggest a need for ongoing education and reinforcement of safe practices to ensure optimal infection prevention and control in healthcare facilities.

Impact of Foodborne Disease in Taiwan during the COVID-19 Pandemic.

Background and Objectives: The coronavirus disease 2019 (COVID-19) pandemic originated in Wuhan, China, in December 2019, the first case diagnosed since January 2020 in Taiwan. The study about the potential impact of the COVID-19 pandemic on event, location, food source, and pathogens of foodborne disease (FBD) is limited in Taiwan. Our aim in this study is to investigate FBD in the context of the COVID-19 pandemic. Materials and Methods: We collected publicly available annual summary data from the FBD dataset in the Taiwan Food and Drug Administration and Certifiable Disease on reported FBD in Taiwan from 2019 to 2020. We used logistic regression to evaluate changes in the occurrence or likelihood of FBD cases and Poisson regression to examine the relative risk (RR) between FBD and climate factors. Results: Similar events occurred in 2019 and 2020, but the total number of FBD cases decreased from 6935 in 2019 to 4920 in 2020. The places where FBD decreased were in schools, hospitals, outdoors, vendors, and exteriors. The top place in FBD shifted from schools to restaurants. The top food source for FBD has changed from boxed food to compound food. Bacillus cereus and Salmonella emerged as the top two observed bacterial pathogens causing FBD. The risk of FBD cases increased with a higher air temperature, with an RR of 1.055 (1.05-1.061, p < 0.001) every 1 °C. Conclusion: The incidence of FBD decreased significantly during the COVID-19 pandemic in Taiwan. This decline may be attributed to protective measures implemented to control the spread of the virus. This shift in locations could be influenced by changes in public behavior, regulations, or other external factors. The study emphasizes the importance of understanding the sources and effectiveness of severe infection prevention policies. The government can use these findings to formulate evidence-based policies aimed at reducing FBD cases and promoting public health. Consumers can reduce the risk of FBD by following safe food handling and preparation recommendations.

Comprehensive Assessment of Hygiene Factors Contributing to Poor Healthcare Facility Conditions in South Sudan: Implications for Public Health

Poor hygiene practices in healthcare facilities contribute significantly to the spread of diseases and compromise public health outcomes, especially in resource-limited settings like South Sudan. This study presents a comprehensive assessment of the multifaceted factors influencing hygiene conditions in selected healthcare facilities in South Sudan. Using a mixed-methods approach, data were collected from Juba Teaching Hospital, Bentiu State Hospital, Nyal Primary Health Care Centre, and Ganyliel Primary Health Care Centre. The study population included medical professionals, hospital staff, patients, and visitors. The results revealed a range of individual, environmental, and health facility factors contributing to poor hygiene. Individual behaviors such as inadequate hand washing, improper waste disposal, and lack of infection control awareness were identified as significant contributors to poor hygiene. Environmental factors such as inadequate sanitation infrastructure, unreliable water supply, and improper waste management practices were also found to exacerbate hygiene challenges. Moreover, health facility factors including overcrowding, inadequate staffing, and limited waste disposal resources further compounded the issue. Statistical analyses demonstrated significant correlations between these factors and poor hygiene outcomes, underscoring the complexity of the problem. Recommendations for improving hygiene standards encompassed comprehensive training programs, infrastructure upgrades, robust infection prevention policies, community engagement initiatives, and quality improvement measures. By addressing these multifactorial challenges, healthcare facilities in South Sudan can enhance hygiene standards, mitigate disease transmission, and improve overall public health outcomes. This study contributes valuable insights to the global discourse on healthcare hygiene and underscores the urgent need for tailored interventions in resource-constrained settings to ensure safe and hygienic healthcare environments.

Data quality review of the Brazilian nosocomial infections surveillance system

BackgroundSurveillance of healthcare-associated infections (HAIs) is an essential component of hospital infection prevention and control systems. We aimed to assess the quality of the data compiled by the Brazilian HAI Surveillance System from pediatric (PICUs) and neonatal intensive care units (NICUs), between 2012 and 2021. MethodsData Quality Review, including adherence, completeness, internal consistency, consistency over time, and consistency of population trend, were computed at both national and state levels based on quality metrics from World Health Organization Toolkit. Incidence rates (or incidence density) of ventilator-associated pneumonia (VAP) and central line-associated bloodstream infection (CLABSI) were obtained from the Brazilian National Nosocomial Infections Surveillance (NNIS) system. Data on sepsis-related mortality, spanning the period from 2012 to 2021, were extracted from the Brazilian National Health Service database (DATASUS). Additionally, correlations between sepsis-related mortality and incidence rates of VAP or CLABSI were calculated. ResultsThroughout the majority of the study period, adherence to VAP reporting remained below 75%, exhibiting a positive trend post-2016. Widespread outliers, as well as inconsistencies over time and in population trends, were evident across all 27 states. Only four states maintained consistent adherence levels above 75% for more than 8 years regarding HAI incidence rates. Notably, CLABSI in NICUs boasted the highest reporting adherence among all HAIs, with 148 periods out of 270 (54.8%) exhibiting reporting adherence surpassing 75%. Three states achieved commendable metrics for CLABSI in PICUs, while five states demonstrated favorable results for CLABSI in NICUs. ConclusionsWhile adherence to HAI report is improving among Brazilian states, an important room for improvement in the Brazilian NNIS exists. Additional efforts should be made by the Brazilian government to improve the reliability of HAI data, which could serve as valuable guidance for hospital infection prevention and control policies.

Clinical and epidemiological characteristics of multi-drug resistant Enterobacterales isolated from King Fahad Hospital of the University, AlKhobar, Saudi Arabia.

Multi-drug resistant (MDR) Enterobacterales remain a major clinical problem. Infections caused by carbapenem-resistant strains are particularly difficult to treat. This study aimed to assess the clinical and epidemiological characteristics of MDR Enterobacterales isolates. A total of 154 non-repetitive clinical isolates, including Escherichia coli (n = 66), Klebsiella pneumoniae (n = 70), and other Enterobacterales (n = 18), were collected from the Diagnostic Microbiology Laboratory at King Fahad Hospital of the University. Most E. coli isolates were collected from urine specimens (n = 50, 75.8%) and resistance against the third and fourth-generation cephalosporins (ceftriaxone, ceftazidime, cefixime, and cefepime) and fluoroquinolones (ciprofloxacin and levofloxacin) was assessed. Clonal relatedness analysis using enterobacterial repetitive intergenic consensus polymerase chain reaction (ERIC-PCR) revealed two clones (E. coli A and B), each comprising two strains. Most K. pneumoniae samples were collected from respiratory specimens (27.1%, 20 samples), and the strains showed overall resistance to most of the antimicrobials tested (54%‒100%). Moreover, clonal-relatedness analysis using ERIC-PCR revealed seven major clones of K. pneumoniae. These findings suggest nosocomial transmission among some identical strains and emphasize the importance of strict compliance with infection prevention and control policies and regulations. Environmental reservoirs could facilitate this indirect transmission, which needs to be investigated.

Description of the epidemiology of healthcare-associated infections in the military hospital of Tunis

Background: Healthcare-associated infections (HAIs) are the most common adverse events in healthcare delivery and the most frequently reported worldwide. Understanding its epidemiology can help stratify the problems and effectively determine prevention and control strategies. Objective: The aim of this study is to describe the epidemiology of HAIs in the military hospital of Tunis. Design: This is a retrospective descriptive study covering the year 2021. It concerns patients who stayed more than 48 h and who developed an infection meeting the criteria of HAIs. Results: A total of 380 HAIs were detected. This represents 2.49 per 1,000 days of hospitalization and 8% of admissions. Men were more affected than women. The anesthesia-intensive care department was the most involved (32.25%). Diabetes mellitus was the most encountered comorbidity (27%). The pulmonary system was the most affected site (46.8%). Germs were identified in 26% of cases. Klebsiella pneumoniae was the most incriminated germ (31%), followed by Staphylococcus aureus (26%). Vancomycin was the most prescribed broad-spectrum antibiotic (24%). Conclusions: Epidemiological surveillance is an essential tool to evaluate the impact of infection prevention and control policies. It would be desirable to reinforce the global policy in our hospital, which is mainly based on the respect of hygiene rules by the staff.

Infection prevention and control policy implementation for CPE: a cross-sectional national survey of healthcare workers reveals knowledge gaps and suboptimal practices

In 2017, Ireland pioneered a unique response to the worsening epidemiology of carbapenemase-producing Enterobacterales (CPE), declaring a national public health emergency. Subsequently, CPE mitigation guidelines and policies were implemented in acute hospitals, focused on patient screening and outbreak management, often by healthcare workers (HCWs) with limited background in infection prevention and control (IPC). CPE risks from sinks and drains remain inadequately controlled. To compare CPE awareness, perceptions of the role of the environment in CPE transmission, and disposal practices of liquid waste from clinical handwashing sinks between IPC HCWs and non-IPC HCWs in Ireland. Between December 2022 and March 2023, HCWs employed in acute hospitals in Ireland between 2017 and 2022 were invited to participate anonymously in a 30-question digital survey. Responses (N=283) were received across several clinical disciplines. In total, 21.6% of respondents were working or had previously worked in IPC roles, 84.1% of whom reported no IPC-related learning needs. In comparison with non-IPC HCWs, more IPC HCWs perceived a risk of pathogen transmission from clean water plumbing (68.9% vs 39.2%; P<0.001) and waste/drainage plumbing (81.2% vs 43.7%; P<0.001). Among nursing and medical staff, only 5.6% of IPC HCWs used clinical handwashing sinks for disposal of liquid waste, compared with 60% of non-IPC HCWs (P<0.001). In comparison with non-IPC HCWs, a greater proportion of IPC HCWs reported that they had witnessed colleagues routinely discarding liquid waste (including nutritional products, antimicrobials and patient body fluids) via clinical handwashing sinks (88.9% vs 77.9%) CONCLUSIONS: Although there is general awareness of the role of the built environment in pathogen transmission, including CPE, familiarity with sink/water-related transmission is greater among IPC HCWs. There may be opportunities to improve disposal practices for liquid waste through education targeting non-IPC HCWs.

1745. Respiratory Syncytial Virus Surveillance of Child Care Attendees, Family Members, and Child Care Providers

Abstract Background Respiratory syncytial virus (RSV) is a leading cause of severe respiratory illness among young children. In the U.S., a third of these children attend child care centers (CCC), where RSV can spread rapidly and be transmitted to family members. The study objective was to determine the incidence of RSV in CCC attendees and their household contacts. Methods The prospective cohort enrolled students (&amp;lt; 6 years old), their household contacts and child care providers (CCP) at six CCC in Ann Arbor, MI from May 2021 to March 2022. Participants completed a symptom diary and weekly nasal swabs. RT-PCR was used to detect RSV. Incidence rates were calculated using Poisson regression. Results A total of 2,342 swabs were collected during 19,121 person-days from 32 students, 13 household child contacts (7 of whom were also students), 45 household adult contacts, and 10 CCP. The incidence rates per 10,000 person-days (95% CI) for total vs. asymptomatic cases were 10.2 (4.2, 24.5) vs. 2.0 (0.3, 14.5) for students, 8.4 (2.1, 33.7) vs. 4.2 (0.6, 30.0) for child contacts, and 5.4 (2.2, 12.9) vs. 1.1 (0.2, 7.6) for adult contacts, respectively. Twelve people tested positive for RSV: 5 (15.6%) were students, 2 (15.4%) were child contacts, 5 (11.1%) were adult contacts, and none were CCP. Semiquantitative cycle threshold was comparable between samples from asymptomatic and symptomatic cases. Three students, 1 child contact and 3 adult contacts had serial positive swabs for a single illness. Asymptomatic cases were detected in 1 (20%) student, 1 (20%) adult contact, and 1 (50%) child contact. Suspected transmission events were observed in 3/24 (12.5%) households with documented infection. All cases were detected between 9/6/21 and 1/17/22, coinciding with RSV circulation in Michigan during the study period. Conclusion This study demonstrates the continued presence of RSV in CCC, including during times of increased disease mitigation, and transmission between children and household contacts may have occurred. Asymptomatic infection was detected, albeit at lower rates than symptomatic infections. Given the incidence of RSV detected, our findings underscore the importance of implementing additional surveillance and infection prevention policies in CCC to mitigate the impact of RSV on vulnerable populations.

Dissemination and characteristics of carbapenem-resistant Klebsiella pneumoniae in nine district hospitals in southwestern China.

Carbapenem-resistant Klebsiella pneumoniae (CRKP) is epidemically transmitted globally, but few studies focused on the prevalence in district-level hospitals. In this study, we investigated CRKP strains collected from nine district hospitals from September 2019 to September 2020, aiming to determine the resistance mechanisms, virulence profiles, and molecular epidemiological characteristics of CRKP in district hospitals in Southwest China. A total of 51 CRKP strains were collected from 9 district-level hospitals. Matrix-assisted laser desorption/ionization-time of flight mass spectrometer was used for strain identification review, and the micro-broth dilution method was used for antibiotic sensitivity detection. Molecular epidemiological investigation of strains was performed by multilocus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE) methods. PCR and efflux pump inhibition tests were used to detect CRKP resistance mechanisms. PCR and serum killing tests were used to detect capsular serotype, virulence-related genes, and virulence validation. The CRKP strains in district hospitals presented high levels of MIC50 and MIC90 in carbapenem antibiotics especially ertapenem and meropenem. A total of 90.2% (46/51) CRKP strains were detected as carbapenemase producers, and the proportion of strains co-expressing carbapenemases was 11.8% (6/51). All CRKP strains were grouped into eight MLST types, and ST11 was the most prevalent genotype. A total of 11.8% (6/51) CRKP isolates were positive for the string test, and three strains of hypervirulent and carbapenem-resistant K. pneumoniae (HV-CRKP) were positive in serum killing test. The molecular typing of all the CRKP isolates was grouped into 29 different PFGE patterns, and 40 ST11 isolates belonged to 20 different PFGE clusters. CRKP strains showed high-level antibiotic resistance and virulence phenotype in district hospitals in Southwest China, which suggested that we should immediately pay attention to the rapid dissemination of the CRKP in regional hospitals. Our study will provide new insights into the epidemiology of CRKP in regional hospitals, which will help regional hospitals develop nosocomial infection prevention and control policies tailored to local conditions.

Occupation-related airborne diseases: Management and prevention of tuberculosis among nurses working in Ekiti State University Teaching Hospital

ABSTRACT Objective: More health workers die from infectious diseases such as tuberculosis (TB) than from any other infectious agent, so the current study is designed to assess TB treatment and preventive measures as they relate to nursing care practice. Materials and Methods: A cross-sectional study was conducted among 82 nurses from December 2022 to January 2023. The data were collected through a self-developed questionnaire and analyzed by frequency table and analysis of variance (ANOVA) statistics. Results: The researchers found that nurses have sufficient knowledge on Infection Prevention and Control (IPC) policy, but not all nurses follow this management protocol, and the reason for their action is addressed in this study. The management and preventive measures used by the participants were identified as: proper cough etiquette/hygiene, working in a well-ventilated area, use of mask, appropriate disposal of used items and so on was reported. Moreover, this study also discovered that there is a positive correlation between nurses who had received training in IPC policy and their use of airborne preventive measures for TB patients (F = 1.87, P = 0.002) as well as a positive correlation between the availability of resources and their adherence to the proper use of airborne preventive measures when caring for TB patients (F = 1.96, P &lt; 0.001). Conclusion: We proposed infection and control training for nurses and adequate equipment supplies to the TB ward which are required in quick TB diagnosis, and must be carried out on a regular basis by health-care personnel, for efficient nursing practice. Ensuring proper safety equipment and isolation units should be available and assessable for nurses or other health workers showing sign or symptoms of TB. Similarly, it is necessary for government to put in place the control and regulations that will safeguard nurses and mandate them to adopt TB prevention protocols, which will aid in lowering the prevalence of TB among nurses.

Mental health nurses' experience of resilience during COVID-19: Aqualitative inquiry.

The COVID-19 pandemic created unprecedented demands and additional stress for nurses in mental health settings. There is no prior evidence on nurses' experience of building and maintaining resilience in the context of work during COVID-19. The aim of this study was to explore the experience and impacts of the COVID-19 pandemic on the resilience of nurses in mental health settings. Data from semi-structured interviews with 20 nurses from an Australian mental health service were analysed using reflexive thematic analysis. Four main themes were generated: experiencing significant disruptions; making sense of shared chaos; having professional commitment; and growing through the challenges. Nurses' practice and teamwork were disrupted by COVID-19 related changes to care models and infection prevention policies. They successfully adjusted by having awareness of self and others' emotions, using mental and emotional self-regulatory strategies, engaging in self-care, using 'bricolage' to create different ways to provide care, and having mutually supportive relationships. Nurses connected to their sense of purpose and professional commitment to fuel their therapeutic work and sustain care delivery. They experienced personal and professional growth with an increased understanding of their strengths and resilience. In the post-pandemic period, although the challenges presented by the pandemic have lessened, there are ongoing negative impacts on nurses' wellbeing. To maintain and strengthen their wellbeing and practice, the findings indicate the importance of professional development in emotional regulation skills, and strategies to strengthen self-care and build collegial relationships in teams. Resilience education can be implemented to support nurses' resilient practice skills.
