Abstract
The digital revolution has significantly altered healthcare, including communicable disease control, with online spaces emerging as vital tools in preventing, identifying and controlling the spread of diseases. However, healthcare professionals, including nurses, need to find a balance between harnessing the benefits of mass communication and mitigating the potentially harmful effects of online misinformation. This article explores the benefits and challenges of using online spaces such as social media platforms in the control of communicable diseases and discusses the potential use of telehealth in reducing the risk of healthcare-associated infection and antimicrobial resistance. The author also describes a framework that nurses can use to explore potential roles and practice in the context of communicable disease control in online spaces.

Not only COVID-19: a systematic review of anti-COVID-19 measures and their effect on healthcare-associated infections. J Hosp Infect 2024; 147:133-145. [PMID: 38423132 DOI: 10.1016/j.jhin.2024.02.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Revised: 02/19/2024] [Accepted: 02/20/2024] [Indexed: 03/02/2024]
Abstract
BACKGROUND Healthcare-associated infections (HAIs) burden healthcare globally. Amid the SARS-CoV-2 pandemic, intensified infection control measures, such as mask usage and hand hygiene, were implemented. AIM To assess the efficacy of these measures in preventing HAIs among hospitalized patients. METHODS Using the PICO framework (Population, Intervention, Comparison, Outcome), the study focused on hospitalized patients and the effectiveness of anti-COVID-19 measures in preventing HAIs. A systematic review of literature published in 2020-2022 was conducted, examining interventions such as mask usage, hand hygiene, and environmental cleaning. FINDINGS This systematic review analysed 42 studies: two in 2020, 21 in 2021, and 19 in 2022. Most studies were from high-income countries (28). Most studies (30 out of 42) reported a reduction in HAIs after implementing anti-COVID-19 measures. Gastrointestinal infections and respiratory tract infections showed significant reduction, unlike bloodstream infections and urinary tract infections. Some wards, like cardiology and neurology, experienced reduced HAIs, unlike intensive care units and coronary care units. There was an increase in studies reporting no effect of hygiene measures on HAIs in 2022, eventually indicating a shift in effectiveness over time. CONCLUSION Anti-COVID-19 measures have shown selective efficacy in preventing HAIs. The study emphasizes the need for context-specific strategies and increased focus on regions with limited resources. Continued research is essential to refine infection control practices, especially in high-risk settings.

Abstract
Bloodstream infection (BSI) is associated with increased morbidity and mortality in the pediatric intensive care unit (PICU) and high healthcare costs. Early detection and appropriate treatment of BSI may improve patient's outcome. Data on machine-learning models to predict BSI in pediatric patients are limited and neither study included time series data. We aimed to develop a machine learning model to predict an early diagnosis of BSI in patients admitted to the PICU. This was a retrospective cohort study of patients who had at least one positive blood culture result during stay at a PICU of a tertiary-care university hospital, from January 1st to December 31st 2019. Patients with positive blood culture results with growth of contaminants and those with incomplete data were excluded. Models were developed using demographic, clinical and laboratory data collected from the electronic medical record. Laboratory data (complete blood cell counts with differential and C-reactive protein) and vital signs (heart rate, respiratory rate, blood pressure, temperature, oxygen saturation) were obtained 72 hours before and on the day of blood culture collection. A total of 8816 data from 76 patients were processed by the models. The machine committee was the best-performing model, showing accuracy of 99.33%, precision of 98.89%, sensitivity of 100% and specificity of 98.46%. Hence, we developed a model using demographic, clinical and laboratory data collected on a routine basis that was able to detect BSI with excellent accuracy and precision, and high sensitivity and specificity. The inclusion of vital signs and laboratory data variation over time allowed the model to identify temporal changes that could be suggestive of the diagnosis of BSI. Our model might help the medical team in clinical-decision making by creating an alert in the electronic medical record, which may allow early antimicrobial initiation and better outcomes.

Abstract
Developing novel antibacterial strategies has become an urgent requisite to overcome the increasing pervasiveness of antimicrobial-resistant bacteria and the advent of biofilms. Aggregation-induced emission-based photosensitizers (AIE PSs) are promising candidates due to their unique photodynamic and photothermal properties. Bioengineering structure-inherent AIE PSs for developing thin film coatings is still an unexplored area in the field of nanoscience. We have adopted a synergistic approach combining plasma technology and AIE PS-based photodynamic therapy to develop coatings that can eradicate bacterial infections. Here, we loaded AIE PSs within biomimetic bacterium-like particles derived from a probiotic strain, Lactobacillus fermentum. These hybrid conjugates are then immobilized on polyoxazoline-coated substrates to develop a bioinspired coating to fight against implant-associated infections. These coatings could selectively kill Gram-positive and Gram-negative bacteria, but not damage mammalian cells. The mechanistic studies revealed that the coatings can generate reactive oxygen species that can rupture the bacterial cell membranes. The mRNA gene expression of proinflammatory cytokines confirmed that they can modulate infection-related immune responses. Thus, this nature-inspired design has opened a new avenue for the fabrication of a next-generation antibacterial coating to reduce infections and associated burdens.

Development and validation of machine learning-based models for predicting healthcare-associated bacterial/fungal infections among COVID-19 inpatients: a retrospective cohort study. Antimicrob Resist Infect Control 2024; 13:42. [PMID: 38616284 PMCID: PMC11017584 DOI: 10.1186/s13756-024-01392-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Accepted: 03/30/2024] [Indexed: 04/16/2024] Open
Abstract
BACKGROUND COVID-19 and bacterial/fungal coinfections have posed significant challenges to human health. However, there is a lack of good tools for predicting coinfection risk to aid clinical work. OBJECTIVE We aimed to investigate the risk factors for bacterial/fungal coinfection among COVID-19 patients and to develop machine learning models to estimate the risk of coinfection. METHODS In this retrospective cohort study, we enrolled adult inpatients confirmed with COVID-19 in a tertiary hospital between January 1 and July 31, 2023, in China and collected baseline information at admission. All the data were randomly divided into a training set and a testing set at a ratio of 7:3. We developed the generalized linear and random forest models for coinfections in the training set and assessed the performance of the models in the testing set. Decision curve analysis was performed to evaluate the clinical applicability. RESULTS A total of 1244 patients were included in the training cohort with 62 healthcare-associated bacterial/fungal infections, while 534 were included in the testing cohort with 22 infections. We found that patients with comorbidities (diabetes, neurological disease) were at greater risk for coinfections than were those without comorbidities (OR = 2.78, 95%CI = 1.61-4.86; OR = 1.93, 95%CI = 1.11-3.35). An indwelling central venous catheter or urinary catheter was also associated with an increased risk (OR = 2.53, 95%CI = 1.39-4.64; OR = 2.28, 95%CI = 1.24-4.27) of coinfections. Patients with PCT > 0.5 ng/ml were 2.03 times (95%CI = 1.41-3.82) more likely to be infected. Interestingly, the risk of coinfection was also greater in patients with an IL-6 concentration < 10 pg/ml (OR = 1.69, 95%CI = 0.97-2.94). Patients with low baseline creatinine levels had a decreased risk of bacterial/fungal coinfections(OR = 0.40, 95%CI = 0.22-0.71). The generalized linear and random forest models demonstrated favorable receiver operating characteristic curves (ROC = 0.87, 95%CI = 0.80-0.94; ROC = 0.88, 95%CI = 0.82-0.93) with high accuracy, sensitivity and specificity of 0.86vs0.75, 0.82vs0.86, 0.87vs0.74, respectively. The corresponding calibration evaluation P statistics were 0.883 and 0.769. CONCLUSIONS Our machine learning models achieved strong predictive ability and may be effective clinical decision-support tools for identifying COVID-19 patients at risk for bacterial/fungal coinfection and guiding antibiotic administration. The levels of cytokines, such as IL-6, may affect the status of bacterial/fungal coinfection.

Abstract
Healthcare-associated infections (HAI) are illnesses acquired during healthcare and are often the most important adverse event during healthcare. With the aim of increasing the effectiveness of disinfection/decontamination processes in the health service with safe and not promote microbial resistance, we propose the development of portable equipment associated with type C ultraviolet light (UVC). The efficiency of the irradiance emitted by the equipment (at dosages 3.5, 5.0, and 60 mJ/cm2) was determined by the action exerted after exposure against four different bacterial (Acinetobacter baumannii, Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus) and three different fungi (Candida albicans, C. parapsilosis, and Aspergillus section Fumigati). It was possible to observe that all treatments were capable of inactivating the bacterial species evaluated (p < 0.05), causing the irreversible death of these microorganisms. The most effective elimination of fungal agents was at a dose of 60 mJ/cm2 of UVC radiation, with a decrease in the fungal inoculum varying between 94% and 100% in relation to the control without exposure. Thus, our study showed that the application of the portable prototype with UVC light (254 nm) at a distance of 48 mm, allowed an average irradiance of 3.5 mW/cm2, with doses of 3.5 ≈ 60 mJ/cm2 (from 1 to 60 s of exposure), which can promote the total reduction of the bacteria evaluated and significantly reduce fungal growth. Therefore, this prototype could be used safely and effectively in the hospital environment, considerably reducing contamination and contributing to the reduction of healthcare-associated infection risk.

Abstract
OBJECTIVE While infection prevention and control are of paramount importance, up until recently an assessment of implementation challenges and performance gaps was lacking. This study explored the barriers to infection prevention and control implementation at selected healthcare facilities, the objective being to find ways to improve their programs. MATERIAL AND METHOD A qualitative approach was applied. Purposive sampling was used to select thirty-three healthcare facilities in Ekiti State, Nigeria. They were globally assessed, and an Infection Prevention and Control team, represented by the Infection Prevention and Control referent in each of the selected facilities trained the participants. Data were collected using the Key Informant Interview Guide and analyzed by means of content and thematic analyses using Atlas.ti software. RESULTS Inadequate infection prevention and control materials, poor waste management, non-compliance of patients with infection prevention and control protocols, and poor infrastructure were identified as major barriers to infection prevention and control implementation. CONCLUSION The study concluded that a number of identified factors hindering infection prevention and control implementation in healthcare facilities in Ekiti State needed to be addressed.

Abstract
Background Lumbar decompression is a commonly performed procedure for the operative management of several degenerative lumbar spinal pathologies. Although open approaches are considered the traditional method, endoscopic techniques represent a relatively novel, less-invasive option to achieve neural element decompression. Here within, we examine if the use of endoscopic techniques decreases the risk of post operative infections. Methods We performed a retrospective cohort analysis to directly compare patients who underwent either open or endoscopic lumbar decompression at a single institution. Rates of postoperative outcomes such as surgical site infection, hospital length of stay, estimated blood loss, and others were compared between the two treatment groups. A multivariate logistic regression model was constructed using patient comorbidities and procedural characteristics to identify the risk factors for surgical site infection. Results 150 patients were identified as undergoing lumbar spine decompression surgeries that met inclusion criteria for the study, of whom 108 (72.0%) underwent open and 61 (28.0%) underwent endoscopic approaches. Unpaired analysis revealed positive associations between operative duration, estimated blood loss, drain placement rates. Multivariate logistic regression did not reveal an association between surgical approach (open versus endoscopic) and the development of surgical site infection. Conclusions Surgical site infections following endoscopic lumbar spine decompression are relatively uncommon, however, after adjusting for baseline differences between patient populations, surgical approach does not independently predict the development of postoperative infection.

Abstract
BACKGROUND This review aimed to synthesize the evidence on infection prevention and control interventions for the prevention of health care-associated infection among health care workers or patients within primary care facilities. METHODS PubMed, CINAHL, EMBASE, and CENTRAL databases were searched for quantitative studies published between 2011 and 2022. Study selection, data extraction, and quality assessment using Cochrane and Joanna Briggs tools, were conducted by independent review with additional sensitivity checking performed on study selection. RESULTS Four studies were included. A randomized trial and a cross-sectional survey, respectively, found no statistical difference in laboratory-confirmed influenza in health care workers wearing N95 versus medical masks (P = .18) and a significant inverse association between the implementation of tuberculosis control measures and tuberculosis incidence (P = .02). For the prevention of surgical site infections following minor surgery, randomized trials found nonsterile gloves (8.7%; 95% confidence interval, 4.9%-12.6%) to be noninferior to sterile gloves (9.3%; 95% confidence interval, 7.4%-11.1%) and no significant difference between prophylactic antibiotics compared to placebo (P = .064). All studies had a high risk of bias. CONCLUSIONS Evidence for infection prevention and control interventions for the prevention of health care-associated infection in primary care is very limited and insufficient to make practice recommendations. Nevertheless, the findings highlight the need for future research.

Abstract
BACKGROUND Surgical site infection (SSI) following cardiac surgery poses a significant challenge for healthcare providers. Despite advances in surgical techniques and infection control measures, SSI remains a leading cause of morbidity and mortality, in addition to being a significant economic burden on healthcare services. Current literature suggests there is a reproducible difference in the incidence of SSI following cardiac surgery between sexes. We aim to assess the sex-specific predictive risk factors for sternal SSI following coronary artery bypass grafting (CABG) in addition to identifying any differences in the causative organisms between groups. METHODS Adult patients undergoing isolated CABG between January 2012 and December 2022 in one UK hospital organization were included. In this 10-year, retrospective observational study, a total of 10,208 patients met the inclusion criteria. Pre-operative risk factors were identified using univariate analysis. To assess dependence between sex and organism or Gram stain, a Pearson Chi-squared test with Yates correction for continuity was performed. RESULTS In total there were 8457 males of which 181 developed a sternal SSI (2.14%) and 1751 females, 128 of whom had a sternal SSI (7.31%). Male patients were found to be significantly more likely to develop an SSI secondary to a Gram-positive organism, whereas female patients were more likely to have a Gram-negative causative organism (P<0.00001). Staphylococcus was statistically more likely to be the causative organism genus in male patients. Pseudomonas aeruginosa was found to be twice as common in the female cohort compared with the male group. CONCLUSION In our study, we found a statistically significant difference in the causative organisms and Gram stain for post-CABG sternal SSIs between males and females. Male patients predominately have Gram-positive associated SSIs, whereas female SSI pathogens are more likely to be Gram negative. The preoperative risk profiles of both cohorts are similar, including being an insulin-dependent diabetic and triple vessel coronary artery disease. Given these findings, it prompts the question, should we be tailoring our SSI treatment strategies according to sex and associated risk profiles?

Chuwa AH. Healthcare-Associated Infections in a Tertiary Care Hospital: Significance of Patient Referral Practices. East Afr Health Res J 2024; 8:111-115. [PMID: 39234348 PMCID: PMC11371007 DOI: 10.24248/eahrj.v8i1.756] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2023] [Accepted: 03/13/2024] [Indexed: 09/06/2024] Open
Abstract
Introduction Nosocomial infections, also known as healthcare-associated infections (HCAIs), are infections that a patient acquires while receiving healthcare services within 48 hours of admission to hospital. In high income countries, an average of 7% of hospitalised patients acquire a nosocomial infection. In low and middle income countries, however, prevalence rates can be as high as 30%. This is due to limited resources and supplies for infection control, inadequate training and lack of compliance with infection prevention and control regulations. Methods A cross-sectional, hospital based study was conducted among patients admitted to a tertiary care facility in Tanzania. A semi-structured questionnaire was used to collect information from 134 patients in different wards. Correlation and multivariate regression analyses were performed to determine the association between the independent variables, i.e. chronic illness, invasive procedures, use of antibiotics and referral status, and the dependent variable, i.e. new symptom, and their level of significance. The significance level was set at P≤ .05. Results A total of 134 patients participated in the study. Of the total number, 61% (n=82) of the patients were male and 43% (n=57) were referrals from other institutions. Fifteen percent (n=21) of the surveyed patients reported a new symptom. There was a positive correlation between referral status and invasive procedure with the occurrence of a new symptom. Multivariate analysis identified 'referral status' as an independent significant factor positively associated with healthcare-associated infetions (P=.041). Conclusions The results indicate a prevalence of 15.7% of healthcare-associated infections, which is unacceptably high for a tertiary care facility. Referral status was independently and significantly associated with HCAI. Improving patient referral patterns and hospital infection control can significantly reduce the risk of healthcare-associated infections.

Knowledge, practice and associated factors towards intravenous cannula-related infection prevention among nurses working at Northwest Amhara Regional State Comprehensive Specialized Hospitals, Ethiopia. BMC Nurs 2024; 23:168. [PMID: 38462599 PMCID: PMC10926565 DOI: 10.1186/s12912-024-01737-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Accepted: 01/15/2024] [Indexed: 03/12/2024] Open
Abstract
BACKGROUND Intravenous cannula-related infections are one of the leading causes of healthcare-associated infections. It leads to morbidity and mortality in hospitalized patients. Nurses play a significant role in the prevention of these infections. Whereas in Ethiopia, there is limited information and published studies done on nurses' knowledge, practice, and associated factors and also most of other available studies done only the magnitude it lack associated factors. The purpose of this study was to assess nurses' knowledge, practice, and associated factors toward intravenous cannula-related infection prevention. METHODS An institution-based cross-sectional study was conducted at Northwest Amhara Regional State Comprehensive Specialized Hospitals on May 1-30/2022. By using single population proportion formula the sample size was determined; we used a 50% proportion value (0.05), and 95% Confidence Interval 5% margin of error. A simple random sampling method was used to select 423 nurses. The data were collected by using structured pretested self-administered questionnaires. Then coded, and enter into epi-data version 4.6 and exported into the statistical package for social science version 23 for cleaning and analyzing the data. Data were presented by texts, tables, and figures. A binary logistic regression model was used to assess the association between variables. Based on the adjusted odds ratio, variables having a p-value less than 0.05 with a 95% confidence interval were used to state associated with the outcome variables. RESULTS A total of 412 nurses participated in this study with 97.4% response rate. The participants had good knowledge and practice in proportions of (54. 9%) and (53. 4%) respectively. Being male, working wards/units, having training, and a higher educational level were factors that were significantly associated to having good knowledge. Working wards/units, having good knowledge, training, and access to guidelines were significantly associated with performing good practice. CONCLUSION The finding of this study revealed that nearly half of the nurses had poor knowledge and practice in intravenous cannula-related infection prevention. As a result, hospital administrators and other concerned stakeholders better to prepare and ensure that guidelines are available, provide training, and develop the educational levels of nurses.

Abstract
Background Oncological surgeries pose an elevated risk of surgical site infections (SSIs) due to their complexity and various associated treatments, impacting patient outcomes and healthcare costs. This has prompted a focus on advanced wound dressings that provide microbial protection, exudate absorption, and improved product performance, enhancing patient satisfaction. Our study aimed to compare the efficacy and safety of Theruptor NXT with the current standard of care (SOC) practice involving cotton/povidone/micropore dressings in the postoperative wound management of oncological surgeries. Methodology A total of 102 patients who underwent oncological surgeries in the Department of Surgical Oncology, Vydehi Institute of Medical Sciences and Research Centre, Bengaluru, India between May and September 2023 were randomized to Theruptor NXT and SOC dressing groups (51 patients each). The incidence of SSIs, wound pain score, cosmetic appearance of the wound, and adverse events were assessed in the two groups at various intervals, i.e., post-surgery day 2 ± 1, day of discharge, and post-surgery day 30 ± 7. Further, the subject satisfaction and product usage were evaluated on post-surgery day 2 ± 1. Results The baseline characteristics were found to be comparable in both groups, i.e., Theruptor NXT and SOC groups. Further, the SSI rates, scar outcomes, and physiological parameters were also similar between the Theruptor NXT and SOC groups, indicating a similar safety profile of both dressings (p > 0.05). However, the product usage assessment revealed statistically significant differences, favoring Theruptor NXT in terms of superior ease of application, stretchability, exudate management, breathability, and non-adherence properties (p < 0.05). Conclusions Our findings suggest that Theruptor NXT wound dressing is a promising, effective, and user-friendly alternative to SOC wound dressing in diverse clinical settings.

Abstract
INTRODUCTION Infection prevention and control (IPC) is crucial in safeguarding patient safety and minimizing the risk of healthcare-associated infections. AIM The study investigated infection prevention and control measures for diagnostic imaging departments at governmental hospitals in the Gaza Strip, Palestine. METHODS The study design was a cross-sectional analytical study. The sample included all radiographers (81) and radiologists (40) working at Al Shifa Medical Complex and European Gaza Hospital (EGH). Data was collected using an interview questionnaire (121) and an observation checklist. Data analysis was conducted using SPSS 26, and the result was significant (P < 0.05). RESULTS Only 27.3 % of the participants revealed the availability of training courses for IPC. More than half of the participants received their last training sessions one year ago, and most of them attended five basic in-service training sessions related to IPC. Radiologists' and medical radiographers' knowledge and practice scores regarding IPC measures were 85.3 % and 61.7 %, respectively, and there were statistically significant differences between the participants' practice domain and their years of experience (p-value .014). There is inadequate hand hygiene among radiographers in the radiology department, and only 29 % of the staff washed their hands immediately upon arrival at the unit. The total score of the Hand Hygiene Self-Assessment Framework domains is almost equal at the two hospitals (280/500). The total score of the eight domains of the IPC Assessment Framework is 568.5/800 for Al Shifa Hospital and 516/800 for EGH, which indicates an intermediate IPC level. CONCLUSION Efforts are needed to enhance the scope and quality of implementation and to concentrate on creating long-term plans to sustain and promote the existing IPC program activities. IMPLICATIONS FOR PRACTICE Regular assessments should be conducted to monitor progress, identify gaps, and guide quality improvement efforts. Assessment feedback should be used to develop targeted interventions and continuously enhance IPC measures.

Abstract
AIM This study aimed to investigate the effect of scenario-based simulation training on infection control, specifically in terms of knowledge, self-efficacy and adherence to standard precautions. BACKGROUND Hospital-associated infections can pose a threat to patient safety and are a critical public health issue that requires attention. DESIGN This quasi-experimental study employed a pre-test/post-test design using a nonequivalent control group. METHODS Infection control nurses were randomly assigned to two groups using lottery methods. The experimental group received scenario-based simulation training, whereas both the experimental and control groups received conventional education. Data were collected from 27 August to 1 December 1 2022. The chi-square test and t-test were used for data analysis. RESULTS The mean scores for knowledge of infection prevention and control (t = 3.679, p < 0.001) and self-efficacy (t = 2.444, p = 0.018) were significantly higher in the experimental group than in the control group. Furthermore, the mean score for adherence to standard precautions was significantly higher in the experimental group than in the control group (t = 2.030, p = 0.048). CONCLUSION Our results suggest that scenario-based simulation training for infection control might be effective in improving knowledge, self-efficacy and adherence to standard precautions. Scenario-based simulation training for infection control may be an effective educational intervention to enhance knowledge, self-efficacy and adherence to standard precautions, thus empowering nurses in infection prevention and control.

Abstract
BACKGROUND The diagnosis of meningitis in non-surgical hospitalized patients is often difficult and diagnostic accuracy of clinical, laboratory, and radiological characteristics is unknown. AIM To assess diagnostic accuracy for individual clinical characteristics of patients suspected of non-surgical nosocomial central nervous system (CNS) infections. METHODS In a prospective multi-centre cohort study in the Netherlands with adults suspected of CNS infections, consecutive patients who underwent a lumbar puncture for the suspicion of a non-surgical nosocomial CNS infection were included. All episodes were categorized into five final clinical diagnosis categories, as reference standard: CNS infection, CNS inflammatory disease, systemic infection, other neurological disease, or non-systemic, non-neurological disease. FINDINGS Between 2012 and 2022, 114 out of 1275 (9%) patients included in the cohort had suspected non-surgical nosocomial CNS infection: 16 (14%) had a confirmed diagnosis, including four (25%) with bacterial meningitis, nine (56%) with viral CNS infections, two (13%) fungal meningitis, and one (6%) parasitic meningitis. Diagnostic accuracy of individual clinical characteristics was generally low. Elevated CSF leucocyte count had the highest sensitivity (81%; 95% confidence interval (CI): 54-96) and negative predictive value (NPV) (96%; 95% CI: 90-99). When combining the presence of abnormalities in neurological or CSF examination, sensitivity for diagnosing a CNS infection was 100% (95% CI: 79-100) and NPV 100% (95% CI: 78-100). CSF examination changed clinical management in 47% of patients. CONCLUSION Diagnostic accuracy for individual clinical characteristics was low, with elevated CSF leucocyte count having the highest sensitivity and NPV.

Healthcare (Basel) 2024; 12:549. [PMID: 38470660 PMCID: PMC10931321 DOI: 10.3390/healthcare12050549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Revised: 02/19/2024] [Accepted: 02/23/2024] [Indexed: 03/14/2024] Open
Abstract
BACKGROUND Healthcare systems represent complex organizations within which multiple factors (physical environment, human factor, technological devices, quality of care) interconnect to form a dense network whose imbalance is potentially able to compromise patient safety. In this scenario, the need for hospitals to expand reactive and proactive clinical risk management programs is easily understood, and artificial intelligence fits well in this context. This systematic review aims to investigate the state of the art regarding the impact of AI on clinical risk management processes. To simplify the analysis of the review outcomes and to motivate future standardized comparisons with any subsequent studies, the findings of the present review will be grouped according to the possibility of applying AI in the prevention of the different incident type groups as defined by the ICPS. MATERIALS AND METHODS On 3 November 2023, a systematic review of the literature according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was carried out using the SCOPUS and Medline (via PubMed) databases. A total of 297 articles were identified. After the selection process, 36 articles were included in the present systematic review. RESULTS AND DISCUSSION The studies included in this review allowed for the identification of three main "incident type" domains: clinical process, healthcare-associated infection, and medication. Another relevant application of AI in clinical risk management concerns the topic of incident reporting. CONCLUSIONS This review highlighted that AI can be applied transversely in various clinical contexts to enhance patient safety and facilitate the identification of errors. It appears to be a promising tool to improve clinical risk management, although its use requires human supervision and cannot completely replace human skills. To facilitate the analysis of the present review outcome and to enable comparison with future systematic reviews, it was deemed useful to refer to a pre-existing taxonomy for the identification of adverse events. However, the results of the present study highlighted the usefulness of AI not only for risk prevention in clinical practice, but also in improving the use of an essential risk identification tool, which is incident reporting. For this reason, the taxonomy of the areas of application of AI to clinical risk processes should include an additional class relating to risk identification and analysis tools. For this purpose, it was considered convenient to use ICPS classification.

Abstract
The success in determining the whole genome sequence of a bacterial pathogen was first achieved in 1995 by determining the complete nucleotide sequence of Haemophilus influenzae Rd using the chain-termination method established by Sanger et al. in 1977 and automated by Hood et al. in 1987. However, this technology was laborious, costly, and time-consuming. Since 2004, high-throughput next-generation sequencing technologies have been developed, which are highly efficient, require less time, and are cost-effective for whole genome sequencing (WGS) of all organisms, including bacterial pathogens. In recent years, the data obtained using WGS technologies coupled with bioinformatics analyses of the sequenced genomes have been projected to revolutionize clinical bacteriology. WGS technologies have been used in the identification of bacterial species, strains, and genotypes from cultured organisms and directly from clinical specimens. WGS has also helped in determining resistance to antibiotics by the detection of antimicrobial resistance genes and point mutations. Furthermore, WGS data have helped in the epidemiological tracking and surveillance of pathogenic bacteria in healthcare settings as well as in communities. This review focuses on the applications of WGS in clinical bacteriology.

Abstract
Disinfection of nosocomial pathogens in hospitals is crucial to combat healthcare-acquired infections, which can be acquired by patients, visitors and healthcare workers. However, the presence of a wide range of pathogens and biofilms, combined with the indiscriminate use of antibiotics, presents infection control teams in healthcare facilities with ongoing challenges in the selection of biocides and application methods. This necessitates the development of biocides and innovative disinfection methods that overcome the shortcomings of conventional methods. This comprehensive review finds the use of hydrogen peroxide vapour to be a superior alternative to conventional methods. Motivated by observations in previous studies, herein, we provide a comprehensive overview on the utilisation of hydrogen peroxide vapour as a superior high-level disinfection alternative in hospital settings. This review finds hydrogen peroxide vapour to be very close to an ideal disinfectant due to its proven efficacy against a wide range of microorganisms, safety to use, lack of toxicity concerns and good material compatibility. The superiority of hydrogen peroxide vapour was recently demonstrated in the case of decontamination of N95/FFP2 masks for reuse to address the critical shortage caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the COVID-19 pandemic. Despite the significant number of studies demonstrating antimicrobial activity, there remains a need to critically understand the mechanism of action by performing studies that simultaneously measure damage to all bacterial cell components and assess the correlation of this damage with a reduction in viable cell count. This can lead to improvement in antimicrobial efficacy and foster the development of superior approaches.

Abstract
Background Healthcare-associated infections pose a substantial threat to the quality of healthcare services. Consequently, it is imperative for hospital organizations to actively support an infection prevention climate, fostering workplace safety and risk mitigation, thereby promoting patient-centered care. Purpose This study aims to explore the interconnectedness between the infection prevention climate, workplace safety, risk mitigation, and patient-centered care. Methods A cross-sectional study design was employed, utilizing a questionnaire administered to 235 healthcare professionals in intensive care and inpatient units at Bandung Kiwari Regional General Hospital. Data analysis was conducted using partial least squares structural equation modeling (PLS-SEM) with SmartPLS 4 and SPSS 25. Results The study revealed several significant relationships, including (1) between infection prevention climate and patient-centered care; (2) infection prevention climate and workplace safety; (3) workplace safety and patient-centered care; (4) infection prevention climate and patient-centered care mediated by workplace safety; (5) infection prevention climate and risk mitigation; (6) risk mitigation and patient-centered care; (7) and the relationship between infection prevention climate and patient-centered care mediated by risk mitigation. Conclusion Infection prevention climate emerges as a crucial intangible value that hospital organizations can cultivate to shape workplace safety. This, in turn, encourages healthcare workers' compliance in implementing infection prevention controls as a form of risk mitigation, ultimately contributing to the provision of patient-centered care.

Longitudinal genomic surveillance of multidrug-resistant Escherichia coli carriage in critical care patients. Microbiol Spectr 2024; 12:e0312823. [PMID: 38171007 PMCID: PMC10846182 DOI: 10.1128/spectrum.03128-23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Accepted: 11/27/2023] [Indexed: 01/05/2024] Open
Abstract
Colonization with multidrug-resistant Escherichia coli strains causes a substantial health burden in hospitalized patients. We performed a longitudinal genomics study to investigate the colonization of resistant E. coli strains in critically ill patients and to identify evolutionary changes and strain replacement events within patients. Patients were admitted to the intensive care unit and hematology wards at a major hospital in Lebanon. Perianal swabs were collected from participants on admission and during hospitalization, which were screened for extended-spectrum beta-lactamases and carbapenem-resistant Enterobacterales. We performed whole-genome sequencing and analysis on E. coli strains isolated from patients at multiple time points. The E. coli isolates were genetically diverse, with 11 sequence types (STs) identified among 22 isolates sequenced. Five patients were colonized by E. coli sequence type 131 (ST131)-encoding CTX-M-27, an emerging clone not previously observed in clinical samples from Lebanon. Among the eight patients whose resident E. coli strains were tracked over time, five harbored the same E. coli strain with relatively few mutations over the 5 to 10 days of hospitalization. The other three patients were colonized by different E. coli strains over time. Our study provides evidence of strain diversity within patients during their hospitalization. While strains varied in their antimicrobial resistance profiles, the number of resistance genes did not increase over time. We also show that ST131-encoding CTX-M-27, which appears to be emerging as a globally important multidrug-resistant E. coli strain, is also prevalent among critical care patients and deserves further monitoring.IMPORTANCEUnderstanding the evolution of bacteria over time in hospitalized patients is of utmost significance in the field of infectious diseases. While numerous studies have surveyed genetic diversity and resistance mechanisms in nosocomial infections, time series of within-patient dynamics are rare, and high-income countries are over-represented, leaving low- and middle-income countries understudied. Our study aims to bridge these research gaps by conducting a longitudinal survey of critically ill patients in Lebanon. This allowed us to track Escherichia coli evolution and strain replacements within individual patients over extended periods. Through whole-genome sequencing, we found extensive strain diversity, including the first evidence of the emerging E. coli sequence type 131 clone encoding the CTX-M-27 beta-lactamase in a clinical sample from Lebanon, as well as likely strain replacement events during hospitalization.

The accuracy of fully-automated algorithms for the surveillance of central venous catheter-related bloodstream infection in hospitalised patients. Antimicrob Resist Infect Control 2024; 13:15. [PMID: 38317207 PMCID: PMC10840273 DOI: 10.1186/s13756-024-01373-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Accepted: 01/26/2024] [Indexed: 02/07/2024] Open
Abstract
BACKGROUND Continuous surveillance for healthcare-associated infections such as central venous catheter-related bloodstream infections (CVC-BSI) is crucial for prevention. However, traditional surveillance methods are resource-intensive and prone to bias. This study aimed to develop and validate fully-automated surveillance algorithms for CVC-BSI. METHODS Two algorithms were developed using electronic health record data from 1000 admissions with a positive blood culture (BCx) at Karolinska University Hospital from 2017: (1) Combining microbiological findings in BCx and CVC cultures with BSI symptoms; (2) Only using microbiological findings. These algorithms were validated in 5170 potential CVC-BSI-episodes from all admissions in 2018-2019, and results extrapolated to all potential CVC-BSI-episodes within this period (n = 181,354). The reference standard was manual record review according to ECDC's definition of microbiologically confirmed CVC-BSI (CRI3-CVC). RESULTS In the potential CVC-BSI-episodes, 51 fulfilled ECDC's definition and the algorithms identified 47 and 49 episodes as CVC-BSI, respectively. Both algorithms performed well in assessing CVC-BSI. Overall, algorithm 2 performed slightly better with in the total period a sensitivity of 0.880 (95%-CI 0.783-0.959), specificity of 1.000 (95%-CI 0.999-1.000), PPV of 0.918 (95%-CI 0.833-0.981) and NPV of 1.000 (95%-CI 0.999-1.000). Incidence according to the reference and algorithm 2 was 0.33 and 0.31 per 1000 in-patient hospital-days, respectively. CONCLUSIONS Both fully-automated surveillance algorithms for CVC-BSI performed well and could effectively replace manual surveillance. The simpler algorithm, using only microbiology data, is suitable when BCx testing adheres to recommendations, otherwise the algorithm using symptom data might be required. Further validation in other settings is necessary to assess the algorithms' generalisability.

J Tissue Viability 2024; 33:75-88. [PMID: 37977894 DOI: 10.1016/j.jtv.2023.11.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 09/22/2023] [Accepted: 11/08/2023] [Indexed: 11/19/2023]
Abstract
AIM Surgical site infections (SSIs) are common healthcare associated infections with serious consequences for patients and healthcare organisations. It is critical that healthcare professionals implement prevention strategies to reduce the incidence of such infections. Prevention strategies are key to reducing the incidence of SSIs. The aim of this systematic review is to describe the effect of interventions conducted in acute care settings on the incidence of SSIs (primary outcome), length of stay, intensive care unit admission, and mortality rate (secondary outcomes). MATERIALS AND METHODS This review is reported using the Preferred Reporting Items for Systematic review and Meta-Analysis checklist. A search was undertaken in Academic Search Complete, CINAHL, ERIC, MEDLINE, PsycARTICLES, PsycINFO and Web of Science for studies published between January 2017 and March 2022. Studies that focused on interventions within acute hospital settings in patients undergoing elective surgery with the aim of reducing the incidences of SSIs were included. Due to heterogeneity results were synthesised narratively. RESULTS In total, 23 studies were included. Findings show that interventions that are effective in reducing the incidences of SSIs have multiple components including care bundles, stakeholder engagement, targeted surveillance and education. Few studies were identified that evaluated the effect of SSI prevention interventions on length of stay and mortality, and none assessed intensive care admission rates. CONCLUSIONS The included interventions varied widely, which made it difficult to draw definitive conclusions regarding specific interventions that reduce SSI. Multicomponent interventions and care bundles showed promise in reducing the occurrence of SSIs. Further studies should focus on standardised evidence-based interventions and compliance using randomised controlled designs.

Cureus 2024; 16:e53947. [PMID: 38468996 PMCID: PMC10925973 DOI: 10.7759/cureus.53947] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/10/2024] [Indexed: 03/13/2024] Open
Abstract
Background In the realm of surgical and postoperative care, the application of wound dressings is a standard practice to facilitate healing, minimize infection risks, and offer a protective barrier against pathogens for optimal recovery. For instance, Theruptor is an active advanced wound care product with patented microbicidal technology. In the present study, we conducted a randomized clinical trial to compare the clinical efficacy and safety of Healthium Theruptor, 3M Tegaderm, and plain gauze dressings in patients undergoing abdominal and joint surgeries. Methodology This was a multicenter, prospective, three-arm, randomized, double-blind study conducted between April and November 2022 at three different sites in India, viz., All India Institute of Medical Sciences, Jodhpur; Mahatma Gandhi Medical College and Research Institute, Puducherry; and SRM Institute of Science and Technology, Chennai. A total of 210 patients were randomized to receive either of the following three interventions: Theruptor, Tegaderm, and plain gauze dressing (n = 70 each) based on computer-generated randomization sequences using sequentially numbered, opaque, sealed envelopes. Demographic data and surgery details were obtained and recorded at baseline. Parameters such as rate of wound healing, incidence of surgical site infections (SSIs), adverse events, product performance, and pain score were assessed and compared during the weekly follow-up visits until 28 days. In addition, wound assessments using the Stony Brook Scar evaluation scale, Cardiff Wound Impact Questionnaire, and Modified Hollander Wound Evaluation Scale were conducted to provide additional insights on the efficacy of the dressings (days 3, 7, 14, and 28). Lastly, the cost of wound management was assessed at the end of the study. The statistical analysis of the data was performed using a one-way analysis of variance followed by a Bonferroni post-hoc test on GraphPad software. Results All three dressings were equally effective in healing the wound and reducing the incidence of SSIs. The median healing time was estimated to be seven days. Further, no significant difference was observed in wound dehiscence, wound pain, clinical wound parameters, cosmetic assessment, and quality of life among the three groups (p > 0.05) during the follow-up visits. However, the product performance of Theruptor and Tegaderm was significantly better than plain gauze dressing in terms of ease of application (82.87% and 84.13% vs. 71.7%), ease of removal (83.09% and 83.67% vs. 70.79%), comfort to wear (82.59% and 84.47% vs. 72.83%), exudate management (84.35% and 85.7% vs. 77.23%), mean wear time in hours (65.57 and 65.92 vs. 49 hours), and mobility of the patient (p < 0.05). Further, the total cost of wound management with Theruptor dressing was significantly lower than with Tegaderm dressing (₹1117.2 ± 269.86 vs. ₹1474 ± 455.63; p < 0.0001). Conclusions Although all three dressings were equally safe and clinically efficacious, Theruptor was more cost-effective with better product performance. Thus, Theruptor may be a considerate option in the postoperative wound management of abdominal and joint surgeries.

Abstract
The laboratory rat emerges as a useful tool for studying the interaction between the host and its microbiome. To advance principles relevant to the human microbiome, we systematically investigated and defined the multitissue microbial biogeography of healthy Fischer 344 rats across their lifespan. Microbial community profiling data were extracted and integrated with host transcriptomic data from the Sequencing Quality Control consortium. Unsupervised machine learning, correlation, taxonomic diversity and abundance analyses were performed to determine and characterize the rat microbial biogeography and identify four intertissue microbial heterogeneity patterns (P1-P4). We found that the 11 body habitats harbored a greater diversity of microbes than previously suspected. Lactic acid bacteria (LAB) abundance progressively declined in lungs from breastfed newborn to adolescence/adult, and was below detectable levels in elderly rats. Bioinformatics analyses indicate that the abundance of LAB may be modulated by the lung-immune axis. The presence and levels of LAB in lungs were further evaluated by PCR in two validation datasets. The lung, testes, thymus, kidney, adrenal and muscle niches were found to have age-dependent alterations in microbial abundance. The 357 microbial signatures were positively correlated with host genes in cell proliferation (P1), DNA damage repair (P2) and DNA transcription (P3). Our study established a link between the metabolic properties of LAB with lung microbiota maturation and development. Breastfeeding and environmental exposure influence microbiome composition and host health and longevity. The inferred rat microbial biogeography and pattern-specific microbial signatures could be useful for microbiome therapeutic approaches to human health and life quality enhancement.

Antimicrobial Resistance Patterns of Staphylococcus Aureus Isolated at a General Hospital in Vietnam Between 2014 and 2021. Infect Drug Resist 2024; 17:259-273. [PMID: 38283112 PMCID: PMC10822110 DOI: 10.2147/idr.s437920] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 01/11/2024] [Indexed: 01/30/2024] Open
Abstract
Purpose Staphylococcus aureus is a commensal bacteria species that can cause various illnesses, from mild skin infections to severe diseases, such as bacteremia. The distribution and antimicrobial resistance (AMR) pattern of S. aureus varies by population, time, geographic location, and hospital wards. In this study, we elucidated the epidemiology and AMR patterns of S. aureus isolated from a general hospital in Vietnam. Methods This was a cross-sectional study. Data on all S. aureus infections from 2014 to 2021 were collected from the Microbiology department of Military Hospital 103, Vietnam. Only the first isolation from each kind of specimen from a particular patient was analyzed using the Cochran-Armitage and chi-square tests. Results A total of 1130 individuals were diagnosed as S. aureus infection. Among them, 1087 strains were tested for AMR features. Most patients with S. aureus infection were in the age group of 41-65 years (39.82%). S. aureus isolates were predominant in the surgery wards, and pus specimens were the most common source of isolates (50.62%). S. aureus was most resistant to azithromycin (82.28%), erythromycin (82.82%), and clindamycin (82.32%) and least resistant to teicoplanin (0.0%), tigecycline (0.16%), quinupristin-dalfopristin (0.43%), linezolid (0.62%), and vancomycin (2.92%). Methicillin-resistant S. aureus (MRSA) and multidrug-resistant (MDR) S. aureus were prevalent, accounting for 73.02% and 60.90% of the total strains respectively, and the strains isolated from the intensive care unit (ICU) had the highest percentage of multidrug resistance (77.78%) among the wards. Conclusion These findings highlight the urgent need for continuous AMR surveillance and updated treatment guidelines, particularly considering high resistance in MRSA, MDR strains, and ICU isolates. Future research focusing on specific resistant populations and potential intervention strategies is crucial to combat this rising threat.

Abstract
Antimicrobial resistance has become a major problem over the years and threatens to remain in the future, at least until a solution is found. Silver nanoparticles (Ag-NPs) and antimicrobial polymers (APs) are known for their antimicrobial properties and can be considered an alternative approach to fighting resistant microorganisms. Hence, the main goal of this research is to shed some light on the antimicrobial properties of Ag-NPs and APs (chitosan (CH), poly-L-lysine (PLL), ε-poly-L-lysine (ε-PLL), and dopamine (DA)) when used alone and complexed to explore the potential enhancement of the antimicrobial effect of the combination Ag-NPs + Aps. The resultant nanocomplexes were chemically and morphologically characterized by UV-visible spectra, zeta potential, transmission electron microscopy, and Fourier-transform infrared spectroscopy. Moreover, the Ag-NPs, APs, and Ag-NPs + APs nanocomplexes were tested against Gram-positive Staphylococcus aureus (S. aureus) and the Gram-negative Escherichia coli (E. coli) bacteria, as well as the fungi Candida albicans (C. albicans). Overall, the antimicrobial results showed potentiation of the activity of the nanocomplexes with a focus on C. albicans. For the biofilm eradication ability, Ag-NPs and Ag-NPs + DA were able to significantly remove S. aureus preformed biofilm, and Ag-NPs + CH were able to significantly destroy C. albicans biofilm, with both performing better than Ag-NPs alone. Overall, we have proven the successful conjugation of Ag-NPs and APs, with some of these formulations showing potential to be further investigated for the treatment of microbial infections.

[PMID: 38275329 PMCID: PMC10812782 DOI: 10.3390/antibiotics13010100] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Revised: 01/03/2024] [Accepted: 01/17/2024] [Indexed: 01/27/2024] Open
Abstract
In the multimodal strategy context, to implement healthcare-associated infection prevention, bundles are one of the most commonly used methods to adapt guidelines in the local context and transfer best practices into routine clinical care. One of the most important measures to prevent surgical site infections is surgical antibiotic prophylaxis (SAP). This narrative review aims to present a bundle for the correct SAP administration and evaluate the evidence supporting it. Surgical site infection (SSI) prevention guidelines published by the WHO, CDC, NICE, and SHEA/IDSA/APIC/AHA, and the clinical practice guidelines for SAP by ASHP/IDSA/SIS/SHEA, were reviewed. Subsequently, comprehensive searches were also conducted using the PubMed®/MEDLINE and Google Scholar databases, in order to identify further supporting evidence-based documentation. The bundle includes five different measures that may affect proper SAP administration. The measures included may be easily implemented in all hospitals worldwide and are based on minimal drug pharmacokinetics and pharmacodynamics knowledge, which all surgeons should know. Antibiotics for SAP should be prescribed for surgical procedures at high risk for SSIs, such as clean-contaminated and contaminated surgical procedures or for clean surgical procedures where SSIs, even if unlikely, may have devastating consequences, such as in procedures with prosthetic implants. SAP should generally be administered within 60 min before the surgical incision for most antibiotics (including cefazolin). SAP redosing is indicated for surgical procedures exceeding two antibiotic half-lives or for procedures significantly associated with blood loss. In principle, SAP should be discontinued after the surgical procedure. Hospital-based antimicrobial stewardship programmes can optimise the treatment of infections and reduce adverse events associated with antibiotics. In the context of a collaborative and interdisciplinary approach, it is essential to encourage an institutional safety culture in which surgeons are persuaded, rather than compelled, to respect antibiotic prescribing practices. In that context, the proposed bundle contains a set of evidence-based interventions for SAP administration. It is easy to apply, promotes collaboration, and includes measures that can be adequately followed and evaluated in all hospitals worldwide.

Abstract
Staphylococcus aureus is considered one of the leading pathogens responsible for infections in humans and animals. The heterogeneous nature of diseases caused by these bacteria is due to the occurrence of multiple strains, differentiated by several mechanisms of antibiotic resistance and virulence factors. One of these is the ability to form biofilm. Biofilm-associated bacteria exhibit a different phenotype that protects them from external factors such as the activity of immune system or antimicrobial substances. Moreover, it has been shown that the majority of persistent and recurrent infections are associated with the presence of the biofilm. Omiganan, an analog of indolicidin - antimicrobial peptide (AMP) derived from bovine neutrophil granules, was found to exhibit high antistaphylococcal and antibiofilm potential. Furthermore, its analog with a reversed sequence (retro-omiganan) was found to display enhanced activity against a variety of pathogens. Based on experience of our group, we found out that counterion exchange can improve the antistaphylococcal activity of AMPs. The aim of this study was to investigate the activity of both compounds against S. aureus biofilm under flow conditions. The advantage of this approach was that it offered the opportunity to form and characterize the biofilm under more controlled conditions. To do this, unique flow cells made of polydimethylsiloxane (PDMS) were developed. The activity against pre-formed biofilm as well as AMPs-treated bacteria was measured. Also, the incorporation of omiganan and retro-omiganan into the channels was conducted to learn whether or not it would inhibit the development of biofilm. The results of the microbiological tests ultimately confirmed the high potential of the omiganan and its retro-analog as well as the importance of counterion exchange in terms of antimicrobial examination. We found out that retro-omiganan trifluoroacetate had the highest biofilm inhibitory properties, however, acetates of both compounds exhibited the highest activity against planktonic and biofilm cultures. Moreover, the developed methodology of investigation under flow conditions allows the implementation of the studies under flow conditions to other compounds.

Abstract
Background Nursing students learn principles of infection prevention and control (IPC) and hand hygiene (HH) in clinical courses, and their learning is reflected in their practice. Objectives The knowledge, attitude, and practice of principles of IPC and HH of the students were measured prior to and after attending an educational workshop. The adherence of the students to the IPC and HH protocols at the hospital was also observed. Methods This study included a pretest-posttest time series follow-up and an observational part. During the first part of the study, students attended a workshop, which was preceded by a pretest. It was then followed by a posttest directly after finishing the workshop and in 12 weeks. Participants were submitted to an observational part by a trained observer to document certain skills taught earlier during the workshop. Settings Students from three nursing schools in Saudi Arabia participated in the study. Participants A total number of 130 completed the study protocol, and 100 completed the observation part. Results Students were found to experience an improvement in their knowledge, beliefs, and commitment scales after the workshop. The attitude scale remained relatively unchanged over different tests. Most students performed the skills properly and adequately, but some failed to perform certain skills, like hand rub, and the proper use of disinfectants.

Abstract
BACKGROUND Limited comparative data exist on acute kidney injury (AKI) risk and AKI-associated outcomes in hospitalized patients with carbapenem-resistant Gram-negative infections (CR-GNIs) treated with a newer β-lactam/β-lactam-β-lactamase inhibitor (BL/BL-BLI)-, polymyxin (PB)- or aminoglycoside (AG)-containing regimen. This study quantified the risk of AKI and AKI-related outcomes among patients with CR-GNIs treated with a newer BL/BL-BLI-, PB- or AG-containing regimen. METHODS A multicentre, retrospective, observational study was performed (2016-20). The study included adult hospitalized patients with (i) baseline estimated glomerular filtration rates ≥30 mL/min/1.73 m2; (ii) CR-GN pneumonia, complicated urinary tract infection or bloodstream infection; and (iii) receipt of newer BL/BL-BLI, PG or AG within 7 days of index CR-GN culture for ≥3 days. Outcomes included AKI, in-hospital mortality and hospital costs. RESULTS The study included 750 patients and most (48%) received a newer BL/BL-BLI. The median (IQR) treatment duration was 8 (5-11), 5 (4-8) and 7 (4-8) days in the newer BL/BL-BLI group, AG group and PB group, respectively. The PB group had the highest adjusted AKI incidence (95% CI) (PB: 25.1% (15.6%-34.6%) versus AG: 8.9% (5.7%-12.2%) versus newer BL/BL-BLI: 11.9% (8.1%-15.7%); P = 0.001). Patients with AKI had significantly higher in-hospital mortality (AKI: 18.5% versus 'No AKI': 5.6%; P = 0.001) and mean hospital costs (AKI: $49 192 versus 'No AKI': $38,763; P = 0.043). CONCLUSIONS The AKI incidence was highest among PB patients and patients with AKI had worse outcomes. Healthcare systems should consider minimizing the use of antibiotics that augment AKI risk as a measure to improve outcomes in patients with CR-GNIs.

Abstract
Acinetobacter baumannii is a relevant bacterium due to its high-resistance profile. It is well known that antimicrobial resistance is primarily linked to mutations and the acquisition of external genomic material, such as plasmids or phages, to which the Clustered Regularly Interspaced Short Palindromic Repeats associated with Cas proteins, or CRISPR-Cas, system is related. It is known that the system can influence the acquisition of foreign genetic material and play a role in various physiological pathways. In this study, we conducted an in-silico analysis using 91 fully assembled genomes of clinical strains obtained from the NCBI database. Among the analyzed genomes, the I-F1 subtype of the CRISPR-Cas system was detected showcasing variations in architecture and phylogeny. Using bioinformatic tools, we determined the presence, distribution, and specific characteristics of the CRISPR-Cas system. We found a possible association of the system with resistance genes but not with virulence determinants. Analysis of the system's components, including spacer sequences, suggests its potential role in protecting against phage infections, highlighting its protective function.

Shorter versus longer duration of antibiotic treatment in children with bacterial meningitis: a systematic review and meta-analysis. Eur J Pediatr 2024; 183:61-71.

Abstract
The optimal duration of antibiotic treatment for the most common bacterial meningitis etiologies in the pediatric population, namely Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis, is not well-established in the literature. Therefore, we aimed to perform an updated meta-analysis comparing shorter versus longer antibiotic treatment in children with meningitis. PubMed, EMBASE, and Cochrane databases were searched for randomized controlled trials (RCTs) that compared shorter (up to 7 days) versus longer (10 days or double the days of the equivalent short course) duration of antibiotic treatment in children with meningitis and reported the outcomes of treatment failure, death, neurologic sequelae, non-neurologic complications, hearing impairment, nosocomial infection, and relapse. Heterogeneity was examined with I2 statistics. RevMan 5.4.1 was used for statistical analysis and RoB-2 (Cochrane) for risk of bias assessment. Of 684 search results, 6 RCTs were included, with a cohort of 1333 children ages 3 weeks to 15.5 years, of whom 49.51% underwent a short antibiotic course. All RCTs included monotherapy with ceftriaxone, except one, which added vancomycin as well. No differences were found comparing the short and long duration of therapy concerning treatment failure, relapse, mortality, and neurologic complications at discharge and at follow-up. Conclusion: Because no statistically significant differences were found between groups for the analyzed outcomes, the results of this meta-analysis support shorter therapy. However, generalizing these results to complicated meningitis and infections caused by other pathogens should be made with caution. (PROSPERO identifier: CRD42022369843). What is Known: • Current recommendations on the duration of antibiotic therapy for bacterial meningitis are mostly based on clinical practice. • Defining an optimal duration of antibiotic therapy is essential for antimicrobial stewardship achievement, improving patient outcomes, and minimizing adverse effects. What is New: • There are no differences between shorter versus longer antibiotic treatment duration in regard to treatment failure, relapse, mortality, neurologic complications, and hearing impairment at discharge and at follow-up.

Abstract
OBJECTIVES Matrix metalloproteinases are enzymes that participate in numerous inflammatory responses and have been targeted as biomarkers in numerous pathologic states. The detection of active matrix metalloproteinase-8 (aMMP-8) using a mouthrinse point-of-care test (POCT) has emerged as a diagnostic marker for periodontitis and other systemic inflammatory states. The objective of this pilot study was to assess the applicability of aMMP-8 POCT in an oral and maxillofacial surgery clinic and to evaluate the relationship between aMMP-8 levels and different patient groups. MATERIALS AND METHODS aMMP-8 POCT samples were collected from patients in an oral and maxillofacial surgery clinic during a one-month period. aMMP-8 levels were analyzed using a chairside lateral-flow immunotest and a digital reader. Clinically relevant patient variables were collected and descriptively evaluated. aMMP-8 levels over 20 ng/ml were considered to be elevated. RESULTS A total of 115 patients were interviewed of which 112 agreed to the test (97.4%). Elevated aMMP-8 levels were observed in 58 (51.8%) patients. Bone loss was noted in 75 (67.0%) patients. Of these patients, aMMP-8 levels were elevated in 47 (62.7%) patients. Patients at an increased risk of infection had 35.5% higher aMMP-8 values on average compared to patients with no prior illnesses. CONCLUSION aMMP-8 POCT provides a non-invasive and reliable method for measuring aMMP-8 levels. Future studies are warranted to assess the clinical relevance between elevated aMMP-8 levels and specific patient groups. CLINICAL RELEVANCE The rapid availability of the test score allows an immediate impact on treatment planning.

Abstract
OBJECTIVES An infection surveillance system based on a hospital's digital twin [4D-Disease Outbreak Surveillance System (4D-DOSS)] is being developed in Singapore. It offers near-real-time infection surveillance and mapping capabilities. This early economic modelling study was conducted, using meticillin-resistant Staphylococcus aureus (MRSA) as the pathogen of interest, to assess the potential cost-effectiveness of 4D-DOSS. METHODS A Markov model that simulates the likelihood of MRSA colonization and infection was developed to evaluate the cost-effectiveness of adopting 4D-DOSS for MRSA surveillance from the hospital perspective, compared with current practice. The cycle duration was 1 day, and the model horizon was 30 days. Probabilistic sensitivity analysis was conducted, and the probability of cost-effectiveness was reported. Scenario analyses and a value of information analysis were performed. RESULTS In the base-case scenario, with 10-year implementation/maintenance costs of 4D-DOSS of $0, there was 68.6% chance that 4D-DOSS would be cost-effective. In a more pessimistic but plausible scenario where the effectiveness of 4D-DOSS in reducing MRSA transmission was one-quarter of the base-case scenario with 10-year implementation/maintenance costs of $1 million, there was 47.7% chance that adoption of 4D-DOSS would be cost-effective. The value of information analysis showed that uncertainty in MRSA costs made the greatest contribution to model uncertainty. CONCLUSIONS This early-stage modelling study revealed the circumstances for which 4D-DOSS is likely to be cost-effective at the current willingness-to-pay threshold, and identified the parameters for which further research will be worthwhile to reduce model uncertainty. Inclusion of other drug-resistant organisms will provide a more thorough assessment of the cost-effectiveness of 4D-DOSS.

Enhanced antibacterial efficacy against antibiotic-resistant bacteria via nitric oxide-releasing ampicillin polymer substrates. J Colloid Interface Sci 2024; 653:1763-1774. [PMID: 37832467 PMCID: PMC10593200 DOI: 10.1016/j.jcis.2023.09.188] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Revised: 09/05/2023] [Accepted: 09/30/2023] [Indexed: 10/15/2023]
Abstract
The emergence of antibiotic-resistant bacteria poses a pressing threat to global health and is a leading cause of healthcare-related morbidity and mortality. Herein, we report the fabrication of medical-grade polymers incorporated with a dual-action S-nitroso-N-acetylpenicillamine-functionalized ampicillin (SNAPicillin) conjugated molecule through a solvent evaporation process. The resulting SNAPicillin-incorporated polymer materials act as broad-spectrum antibacterial surfaces that improve the administration efficacy of conventional antibiotics through the targeted release of both nitric oxide and ampicillin. The polymer surfaces were characterized by scanning electron microscopy and static contact angle measurements. The nitric oxide (NO) release profile and diffusion of SNAPicillin from polymers were quantified using a chemiluminescence-based nitric oxide analyzer (NOA) and ultraviolet-visible (UV-vis) spectroscopy. As a result, the films had up to 2.96 × 10-7 mol cm-2 of total NO released within 24 hr. In addition, >79 % of the SNAPicillin reservoir was preserved in the polymers after 24 hr of incubation in the physiological environment, indicating their longer-term NO release ability and therapeutic window for antibacterial effects. The SNAPicillin-incorporated polymers reduced the viability of adhered bacteria in culture, with >95 % reduction found against clinically relevant strains of Staphylococcus aureus (S. aureus). Furthermore, SNAPicillin-modified surfaces did not elicit a cytotoxic effect toward 3T3 mouse fibroblast cells, supporting the material's biocompatibility in vitro. These results indicate that the complementary effects of NO-release and ampicillin in SNAPicillin-eluting polymers can enhance the properties of commonly infected medical device surfaces for antibacterial purposes.

Abstract
OBJECTIVES Bloodstream infections caused by carbapenem-resistant bacteria have increased globally. Solid-organ transplant recipients are more prone to these infections. This study aimed to compare the clinical courses of carbapenem-susceptible and carbapenem-resistant Enterobacteriaceae bloodstream infections and to identify risk factors for carbapenem resistance in solid-organ transplant recipients. MATERIALS AND METHODS For this retrospective descriptive study, data for solid-organ transplant recipients (age ≥18) treated from 2015 to 2022 were obtained from medical records. Enterobacteriaceaepositive blood culture was screened from laboratory data. RESULTS Among 72 patients, there were 100 bacteremia episodes. Patients included 40 kidney (55.6%), 21 liver (29.2%), 7 heart (9.7%), and 4 combined liver and kidney (5.6%) transplant recipients. Fifty-seven bacteremia episodes were recorded between 2015 and 2020, and 43 bacteremia episodes were recorded between 2020 and 2022. Carbapenem resistance was reported in 15.8% of patients before 2020, whereas this rate increased to 39.5% after 2020 (P = .007). Pitt bacteremia score ≥4 (P < .001), Charlson comorbidity index ≥4 (P = .021), chronic liver disease (P = .015), septic shock at admission (P = .001), hypotension at admission (P = .006), bacteremia episodes 48 hours after hospitalization (P = .004), hospitalization in the past 3 months (P = .004), and prior invasive procedure (P = .043) were significant factors for carbapenem resistance. Logistic regression analysis showed that bacteremia 48 hours after hospitalization (P = .002) and hospitalization in the past 3 months (P = .006) were independent risk factors. CONCLUSIONS Carbapenem resistance increased significantly over the years. Bacteremia 48 hours after hospitalization and hospitalization within the past 3 months were determined to be risk factors for carbapenem resistance. Carbapenem-resistant infections are still nosocomial infections. Patients should be hospitalized for as a short time as possible, and both patients and their physicians should follow infection control and prevention methods.

Abstract
Aim: To evaluate the lactate/albumin ratio and its relation to mortality in children with nosocomial infections. Materials & methods: One hundred six children were included in this study. Blood gas and albumin levels were analyzed at the first, 24th and 48th h. Results: The types of detected microbial agents, signs of sepsis, development of septic shock and mortality rates were different. The first-, 24th- and 48th h lactate levels of the children who died were higher than those of the living children, but the albumin levels were lower. The highest area under the curve value for the lactate/albumin ratio was detected at the 24th h. Conclusion: Lactate/albumin ratio can be used to predict mortality in children with nosocomial infections.

Abstract
The skin is the biggest organ in the human body. It is the first line of protection against invading pathogens and the starting point for the immune system. The focus of this review is on the use of amphibian-derived peptides and antimicrobial peptides (AMPs) in the treatment of wound healing. When skin is injured, a chain reaction begins that includes inflammation, the formation of new tissue, and remodelling of existing tissue to aid in the healing process. Collaborating with non-immune cells, resident and recruited immune cells in the skin remove foreign invaders and debris, then direct the repair and regeneration of injured host tissues. Restoration of normal structure and function requires the healing of damaged tissues. However, a major issue that slows wound healing is infection. AMPs are just one type of host-defense chemicals that have developed in multicellular animals to regulate the immune response and limit microbial proliferation in response to various types of biological or physical stress. Therefore, peptides isolated from amphibians represent novel therapeutic tools and approaches for regenerating damaged skin. Peptides that speed up the healing process could be used as therapeutic lead molecules in future research into novel drugs. AMPs and amphibian-derived peptides may be endogenous mediators of wound healing and treat non-life-threatening skin and epithelial lesions. Thus, the present article was drafted with to incorporate different peptides used in wound healing, their method of preparation and routes of administration.

Abstract
BACKGROUND Bacterial whole-genome sequencing (WGS) and determination of genetic relatedness is an important tool for investigation of epidemiologically suspected outbreaks. AIM This prospective cohort study evaluated a comprehensive, prospective bacterial WGS-based surveillance programme for early detection of transmission of most bacterial pathogens among patients at a paediatric oncology hospital. METHODS Cultured bacterial isolates from clinical diagnostic specimens collected prospectively from both inpatient and outpatient encounters between January 2019 and December 2021 underwent routine WGS and core genome multi-locus sequence typing to determine isolates' relatedness. Previously collected isolates from January to December 2018 were retrospectively analysed for identification of prior or ongoing transmission. Multi-patient clusters were investigated to identify potential transmission events based on temporal and spatial epidemiological links and interventions were introduced. FINDINGS A total of 1497 bacterial isolates from 1025 patients underwent WGS. A total of 259 genetically related clusters were detected, of which 18 (6.9%) multi-patient clusters involving 38 (3.7%) patients were identified. Sixteen clusters involved two patients each, and two clusters involved three patients. Following investigation, epidemiologically plausible transmission links were identified in five (27.8%) multi-patient clusters. None of the multi-patient clusters were suspected by conventional epidemiological surveillance. CONCLUSION Bacterial WGS-based surveillance for early detection of hospital transmission detected several limited multi-patient clusters that were unrecognized by conventional epidemiological methods. Genomic surveillance helped efficiently focus interventions while reducing unnecessary investigations.

Abstract
Polysaccharides originating from marine sources have been studied as potential material for use in wound dressings because of their desirable characteristics of biocompatibility, biodegradability, and low toxicity. Marine-derived polysaccharides used as wound dressing, provide several benefits such as promoting wound healing by providing a moist environment that facilitates cell migration and proliferation. They can also act as a barrier against external contaminants and provide a protective layer to prevent further damage to the wound. Research studies have shown that marine-derived polysaccharides can be used to develop different types of wound dressings such as hydrogels, films, and fibres. These dressings can be personalised to meet specific requirements based on the type and severity of the wound. For instance, hydrogels can be used for deep wounds to provide a moist environment, while films can be used for superficial wounds to provide a protective barrier. Additionally, these polysaccharides can be modified to improve their properties, such as enhancing their mechanical strength or increasing their ability to release bioactive molecules that can promote wound healing. Overall, marine-derived polysaccharides show great promise for developing effective and safe wound dressings for various wound types.

Abstract
Catheter-associated urinary tract infections (CAUTIs) frequently occur following the insertion of catheters in hospitalized patients, often leading to severe clinical complications. These complications are exacerbated by biofilm-forming organisms such as Staphylococcus aureus, contributing to the emergence of multidrug-resistant (MDR) strains, which complicates treatment strategies. This study aims to investigate the antibacterial, antibiofilm, and antiadhesive properties of duloxetine against S. aureus in the context of CAUTI. Our findings demonstrate that duloxetine exhibits significant antibacterial activity, as evidenced by the agar diffusion method. A minimal inhibitory concentration (MIC) of 37.5 μg/mL was established using the microdilution method. Notably, duloxetine displayed inhibitory effects against biofilm formation on polystyrene surfaces up to its MIC level, as demonstrated by the crystal violet method. Intriguingly, the study also revealed that duloxetine could prevent biofilm formation at lower concentrations and reduce mature biofilms, as confirmed by scanning electron microscopy (SEM) and quantitative biofilm assays. Furthermore, duloxetine-coated silicone catheter tubes exhibited antibacterial properties against S. aureus in a bladder model, visualized by confocal laser scanning microscopy (CLSM) and corroborated through FDA and PI staining, highlighting noticeable morphological changes in S. aureus post-treatment. In conclusion, this study presents duloxetine as a promising alternative agent with antibacterial and antiadhesive properties against S. aureus in the prevention and management of CAUTI, warranting further exploration in the clinical setting.

Abstract
Background Among patients with nosocomial bacterial pneumonia, those who decompensated to requiring mechanical ventilation (vHABP) faced the highest mortality followed by ventilator-associated pneumonia (VABP) and non-ventilated hospital-acquired pneumonia (nvHABP). The objectives of this study were to identify risk factors associated with the development and mortality of vHABP and to evaluate antibiotic management. Methods A multicenter retrospective cohort study of adult inpatients with nosocomial pneumonia during 2014-2019 was performed. Groups were stratified by vHABP, nvHABP, and VABP and compared on demographics, clinical characteristics, treatment, and outcomes. Multivariable models were generated via machine learning to identify risk factors for progression to vHABP as well as pneumonia-associated mortality for each cohort. Results 457 patients (32% nvHABP, 37% vHABP, and 31% VABP) were evaluated. The vHABP and nvHABP groups were similar in age (median age 66.4 years) with 77% having multiple comorbidities but more vHABP patients had liver disease (18.2% vs. 7.7% p = 0.005), alcohol use disorder (27% vs. 7.1%, p < 0.0001), and were hospitalized within the past 30 days (30.4% vs. 19.5%, p = 0.02). An immediate need for ventilatory support occurred in 70% of vHABP patients on the day of diagnosis. Mortality was the highest in vHABP followed by VABP and nvHABP groups (44.6% vs. 36% vs. 14.3%, p < 0.0001). Nearly all (96%) vHABP patients had positive cultures, with Gram-negative pathogens accounting for 58.8% whereby 33.0% were resistant to extended-spectrum β-lactams (ESBLs), ceftriaxone (17.5%), fluoroquinolones (20.6%), and carbapenems (12.4%). Up to half of the vHABP patients with ESBL-Enterobacterales or P. aeruginosa did not receive an effective empiric regimen; over 50% increase in mortality rate was observed among patients whom effective therapy was initiated past the day of pneumonia diagnosis. Risk factors associated with vHABP development were alcohol use disorder, APACHE II score, vasopressor therapy prior to infection, and culture positive for ESBL-Enterobacterales whereas history of hospitalization in the past 30 days, active malignancy, isolation of ceftriaxone-resistant pathogens or Pseudomonas aeruginosa, and vasopressor therapy were risk factors for vHABP-associated mortality. Conclusion Patients with vHABP experienced an acute and severe decompensation upon diagnosis. The risk factors identified in this study could provide actionable data for clinicians to identify those at risk for vHABP at the onset of pneumonia and to target antimicrobial stewardship efforts to improve treatment success.

Abstract
Biofilm infections are a serious threat to public health, resistant to traditional treatments and host immune defenses. Biofilm infections are often polymicrobial, related to chronic wounds, medical devices (eg, knee replacements, catheters, tubes, contact lenses, or prosthetic valves) and chronic recurring diseases. Biofilms are more complex than nonadhered planktonic bacteria and produce a structure that prevents damage to the bacteria within the biofilm structure. The structure provides a hidden route to feed and nurture the bacteria allowing for ongoing spread of the bacteria.

Abstract
Background and Purpose Emergence of fungi as a pathogenic threat presents a significant challenge to public health, notably in intensive care units (ICUs) and among immunocompromised patients. Various factors, including sepsis-induced barrier disruptions, immune system dysfunction, and extremes of age, contribute to increased susceptibility to fungal infections. Hospital practices, such as prolonged surgeries, broad-spectrum antibiotic use, and invasive procedures, further exacerbate the risk. Fungal bloodstream infections, particularly those caused by Candida albicans, rank among the most common hospital-acquired infections, leading to substantial morbidity and mortality. The global rise in invasive candidiasis, particularly due to non-albicans Candida species, presents challenges in the diagnosis and treatment due to nonspecific symptoms and emerging antifungal resistance. Nanotechnology interventions particularly by utilizing green synthesized copper nanoparticles could possibly provide a novel solution to combat microbial colonization, biofilm formation, and drug resistance. This study aimed to assess the prevalence of candidemia, identify the distribution of causative Candida species, and understand their susceptibility patterns to commonly used antifungal agents for effective management in ICU settings. Additionally, the study sought to explore the in vitro anti-Candida activity of green copper nanoparticles synthesized using Euphorbia milii des moul extract. Materials and Methods This study was conducted at Microbiology Laboratory of Maharishi Markandeshwar Institute of Medical Sciences and Research from January to December 2022, focused on ICU patients suspected of bloodstream infections. Blood samples were collected aseptically and processed using BD BACTECTM culture vials. Identification of organisms was performed via the Vitek-2 system by confirming candidemia with positivity in both blood samples. After that antifungal susceptibility testing was also performed against Clinical and Laboratory Standards Institute recommended antifungal drug using Vitek 2 system. G-CuNPs were synthesized using E. milii Des moul extract and possessed for physiochemical characterization. The anti-Candida activity of G-CuNPs was evaluated through the MTT assay and time kill assay. After that generation of intracellular reactive oxygen species and DNA degradation were evaluated to understand its mechanism. Results This study identified a candidemia rate of 7.3% (58/789).

Awareness of health care workers with appropriate infection control practices related to multi-patient use of Close Loop Medication Administration device. Infect Prev Pract 2023; 5:100323. [PMID: 38028360 PMCID: PMC10665828 DOI: 10.1016/j.infpip.2023.100323] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2023] [Accepted: 08/01/2023] [Indexed: 12/01/2023] Open
Abstract
Background Portable computerized devices represent a potential source of healthcare infections. The objective was to assess the knowledge, attitudes, and practices (KAP) of healthcare workers (HCWs) toward infection control practices used with Close Loop Medication Administration (CLMA) devices. Additionally, to quantify the impact of education and training on the bacterial burden on CLMA devices. Methods The study design consisted of two steps: a cross-sectional study was conducted among HCWs working in a tertiary care center in Riyadh, Saudi Arabia. A 32-item questionnaire was used to assess KAP information. The second step was environmental samples collected from the surfaces of CLMA devices before and after implementing a multifaceted intervention. Result A total of 325 HCWs were included in the study. The mean age was 32.6±7.4 years. The majority were females (92%) and nurses (91.3%). The overall KAP score was 74.8%, 74.2% adequate knowledge, 79.3% positive attitude, and 71.3% appropriate practices. KAP score was better (≥ median KAP score) among HCWs working in laboratory and organ transplant units (P<0.001). It was also better among those with a longer duration of work experience (P<0.001) and those who received related training (P<0.001). Approximately 75% of HCWs expressed their need for more information about CLMA. Post-interventional samples had much lower bacterial burden, with the positive rate reduced from 51.4% before intervention to 16.8% after intervention (P<0.001). Conclusions Awareness and behavior of HCWs about appropriate infection control practices related to portable devices is still inadequate. A multifaceted intervention including education and training significantly reduces the bioburden on portable devices.

Abstract
The increasing demand for healthcare-acquired infection (HAI) control practices and services has intensified the need to evaluate care quality. The World Health Organization (WHO) introduced an infection prevention and control (IPC) framework to mitigate the impact of HAIs, crucial for ensuring patient safety in hospitals. HAIs acquired after hospitalization pose significant challenges due to factors such as compromised immunity, invasive medical procedures, and antibiotic-resistant pathogens, which have dire consequences, including higher mortality rates and increased healthcare costs. Healthcare workers (HCWs) are critical in implementing IPC measures. Infection control programs that include strategies such as hand hygiene, personal protective equipment (PPE), environmental cleaning, and surveillance have become standard. However, challenges such as resistance to change, resource limitations, patient turnover, and variability in patient conditions persist. Strategies to maintain hospital infection control involve rigorous compliance monitoring, staff education, advanced technologies such as artificial intelligence (AI), machine learning (ML), telemedicine, and innovative sanitation methods. The future of hospital infection control may involve increased integration of environmental monitoring, antimicrobial stewardship, and patient participation while leveraging collaboration among healthcare facilities. The review highlights the criticality of hospital infection control and suggests trends and opportunities to strengthen prevention efforts and patient safety.

Abstract
Background Surgical site infections are common and expensive infections that can cause fatalities or poor patient outcomes. To prevent these infections, antibiotic prophylaxis is used. However, excessive antibiotic use is related to higher costs and the emergence of antimicrobial resistance. Objectives The present meta-analysis aimed to compare the effectiveness of a single dosage versus several doses of antibiotics in preventing the development of surgical site infections. Methods PubMed was used to find clinical trials evaluating the effectiveness of a single dosage versus several doses of antibiotics in avoiding the development of surgical site infections. The study included trials that were published between 1984 and 2022. Seventy-four clinical trials were included in the analysis. Odds ratios were used to compare groups with 95% confidence intervals. The data were displayed using OR to generate a forest plot. Review Manager (RevMan version 5.4) was used to do the meta-analysis. Results Regarding clean operations, there were 389 surgical site infections out of 5,634 patients in a single dose group (6.90%) and 349 surgical site infections out of 5,621 patients in multiple doses group (6.21%) (OR = 1.11, lower CI = 0.95, upper CI = 1.30). Regarding clean-contaminated operations, there were 137 surgical site infections out of 2,715 patients in a single dose group (5.05%) and 137 surgical site infections out of 2,355 patients in multiple doses group (5.82%) (OR = 0.87, lower CI = 0.68, upper CI = 1.11). Regarding contaminated operations, there were 302 surgical site infections out of 3,262 patients in a single dose group (9.26%) and 276 surgical site infections out of 3,212 patients in multiple doses group (8.59%) (OR = 1.11, lower CI = 0.84, upper CI = 1.47). In general, there were 828 surgical site infections out of 11,611 patients in a single dose group (7.13%) and 762 surgical site infections out of 11,188 patients in multiple doses group (6.81%) (OR = 1.05, lower CI = 0.93, upper CI = 1.20). The difference between groups was not significant. Conclusion The present study showed that using a single-dose antimicrobial prophylaxis was equally effective as using multiple doses of antibiotics in decreasing surgical site infections.

Abstract
OBJECTIVE This study aims to determine the frequency of urinary tract infection (UTI), identify the isolated bacteria, and assess antibiotic sensitivity in patients undergoing orthopedic implant fixation for hip fractures. METHODOLOGY After ethical approval from the institutional review board, this retrospective cross-sectional study was conducted at the Orthopedic Surgery Department of Dow University Hospital Karachi from June 2022 to June 2023. Through non-probability consecutive sampling, 186 patients above 16 years of age, of either gender, presenting with hip fractures such as intracapsular or extracapsular fractures, who underwent surgical fixation, were included in the study. A urine sample for urinalysis of these patients was sent on admission. Patients who presented with open fractures or those treated with conservative management were excluded from the study. The fracture diagnosis was confirmed on radiographs. All other relevant baseline investigations were also performed before surgery, per protocol, and urine-detailed and cultured reports were followed. In addition, each patient was asked about common symptoms of UTI before surgery and then diagnosed with UTI on positive urine culture and sensitivity (CS). RESULTS Out of 186 hip fracture patients, 98 (52.7%) were males and 88 (47.3%) were females, with a mean age of 61.03 ± 16.43 (16-96) years. Pre-operative UTI symptoms were reported by 79 patients, including dysuria (16; 20.3%), polyuria (19; 24.0%), and burning (44; 55.7%). UTI was diagnosed on culture and sensitivity report in 65 (34.9%) patients with Escherichia coli as commonly diagnosed bacteria 35 (53.8%), followed by Enterococcus 8 (12.4%), Klebsiella 7 (10.9%), Pseudomonas aeruginosa 3 (4.7%), and Acinetobacter 2 (3.1%) patients. E. coli was sensitive to amikacin, amoxicillin/clavulanic acid, ampicillin, cefixime, ceftriaxone, cefuroxime, ciprofloxacin, colistin, cotrimoxazole, fosfomycin, gentamycin, levofloxacin, meropenem, nitrofurantoin, polymyxin B, and piperacillin-tazobactam. CONCLUSION Urinary tract infection is common in patients undergoing orthopedic implant fixation for hip fractures, which can lead to potentially serious outcomes. Overall, hygiene, prompt treatment, and standard protocol should be utilized to treat those infected and minimize the spread.
