Abstract
Background The urinary catheter usually leads to a catheter-associated urinary tract infection (CAUTI) contributing to further morbidity and mortality. There is very limited data on the CAUTI incidence rate in high-dependency units (HDUs) in the Kingdom of Saudi Arabia. The institutional CAUTI incidence rate in HDU was six times higher compared to the United States National Healthcare Safety Network (US-NHSN) in 2021. Objective To reduce 50% CAUTI incidence rate by the end of 2022. Method A prospective study was conducted in tertiary HDU from January 2022 to June 2023. A gap analysis was assessed between the hospital practices and the Society Healthcare Epidemiology of America/Infectious Diseases Society of America (SHEA/IDSA) basic recommendations. The Kotter and Rathgebers' changing behavior model was applied at the beginning of the project. Formal education and prevention of CAUTI were applied using the National Strategy Model. Surveillance and statistical data analysis were carried out using US-NHSN guidelines. Results The overall CAUTI incidence rate declined from 7.07- to 3.57/1000 urinary catheter days despite of significant increase in the utilization ratio from 0.79 to 0.94 (P value 0.0001). The compliance rate of the bundle CAUTI prevention was improved and sustained above 90%. A CAUTI incidence rate reduction was observed following the combination of the changing behavior and SHEA/IDSA of CAUTI prevention models over 18 months. Conclusion We assumed the combination of the changing behavior and the prevention models for a long period is useful in reducing the CAUTI incidence rate and possibly applied to reduce other healthcare-associated infections.

Abstract
OBJECTIVES Catheter-associated urinary tract infections (CAUTI) are a significant cause of morbidity and financial burden to healthcare systems. The aim of this study was to develop and implement a program designed to reduce Foley catheter use days and associated CAUTI rates. METHODS A retrospective evaluation of a multi-modal program aimed toward reducing Foley catheter use days and associated CAUTI rates across the Indiana University Health (IUH) system was conducted. IUH is comprised of 16 hospitals and 2,703 available beds. The program included the adoption of new technologies with evidence-based clinical training materials based on change management and feedback from clinicians. National Healthcare Safety Network Standardized Infection Ratio (SIR), Standardized Utilization Ratio (SUR), and Incidence Density Ratio (IDR) rates were assessed. RESULTS Implementation of the multi-modal program resulted in a significant reduction in SIR, SUR, and IDR in the post-implementation compared to the baseline periods. CONCLUSIONS Through CAUTI bundle workflow assessments, education, and interventions designed to standardize practice variation, the program was successfully implemented and resulted in a significant decrease in Foley Catheter use days, and associated CAUTI rates.

Abstract
Urinary catheters and other medical devices associated with the urinary tract such as stents are major contributors to nosocomial urinary tract infections (UTIs) as they provide an access path for pathogens to enter the bladder. Considering that catheter-associated urinary tract infections (CAUTIs) account for approximately 75% of UTIs and that UTIs represent the most common type of healthcare-associated infections, novel anti-infective device technologies are urgently required. The rapid rise of antimicrobial resistance in the context of CAUTIs further highlights the importance of such preventative strategies. In this review, the risk factors for pathogen colonization in the urinary tract are dissected, taking into account the nature and mechanistics of this unique environment. Moreover, the most promising next-generation preventative strategies are critically assessed, focusing in particular on anti-infective surface coatings. Finally, emerging approaches in this field and their likely clinical impact are examined.

Abstract
Present-day healthcare employs several types of invasive devices, including urinary catheters, to improve medical wellness, the clinical outcome of disease, and the quality of patient life. Among urinary catheters, the Foley catheter is most commonly used in patients for bladder drainage and collection of urine. Although such devices are very useful for patients who cannot empty their bladder for various reasons, they also expose patients to catheter-associated urinary tract infections (CAUTIs). Catheter provides an ideal surface for bacterial colonization and biofilm formation, resulting in persistent bacterial infection and severe complications. Hence, rigorous efforts have been made to develop catheters that harbour antimicrobial and anti-fouling properties to resist colonization by bacterial pathogens. In this regard, catheter modification by surface functionalization, impregnation, blending, or coating with antibiotics, bioactive compounds, and nanoformulations have proved to be effective in controlling biofilm formation. This review attempts to illustrate the complications associated with indwelling Foley catheters, primarily focussing on challenges in fighting CAUTI, catheter colonization, and biofilm formation. In this review, we also collate scientific literature on catheter modification using antibiotics, plant bioactive components, bacteriophages, nanoparticles, and studies demonstrating their efficacy through in vitro and in vivo testing.

Abstract
Central line-associated bloodstream infections (CLABSIs) and catheter-associated urinary tract infections (CAUTIs) are quality metrics for many ICUs, and financial ramifications can be applied to hospitals and providers who perform poorly on these measures. Despite some perceived benefits to tracking these metrics, there are a range of issues associated with this practice: lack of a solid evidence base that documenting them has led to decreased infection rates, moral distress associated with identifying these infections, problems with their definitions, and others. We discuss each of these concerns while also including international perspectives then recommend practical steps to attempt to remediate use of the CLABSI and CAUTI metrics. Specifically, we suggest forming a task force consisting of key stakeholders (e.g., providers, Centers for Medicare & Medicaid Services (CMS), patients/families) to review CLABSI and CAUTI-related issues and then to create a summary statement containing recommendations to improve the use of these metrics.

Abstract
Hospital-acquired infections (HAIs) remain one of the major challenges faced by the global healthcare system. The increasing rate of pathogenic resistance against antibiotics suggests that alternative treatments are needed to control recurrent infections. Catheter-associated urinary tract infections (CAUTIs) are the third most common type of HAI worldwide, and this is mainly due to indwelling devices being excellent substrates for bacterial adhesion and growth. Subsequent biofilm formation on the implant surface acts as a constant nidus of bacteria and infection, thereby contributing to increased rates of patient morbidity and mortality. Here, we propose a simple and cost-effective method to sterilize silicone-based implant surfaces and prevent initial bacterial colonization, using Polydimethylsiloxane (PDMS) and an embedded ruthenium photosensitizer (PS). Exposure to LED light triggers potent photokilling action, resulting in significant bactericidal activity as evidenced by the number of adherent bacteria being below the level of detection (<10 CFU/mL) after 24 h. Live/dead staining studies using fluorescence microscopy indicated significant reduction in surface-adhered bacterial growth and biofilm formation. This potent antibacterial activity was verified in vivo, with exposure of contaminated PDMS coupons containing PS to LED prior to implantation resulting in over 99.5% reduction in adherent bacteria compared to controls over the 3-day implantation period. Histological analysis of the implantation site of PDMS+PS samples, in the absence of bacteria, revealed no adverse reactions. This was also confirmed using in vitro cytotoxicity studies. Tensile strength, surface roughness, hydrophobicity, and the development of encrustation of surface-treated groups exhibit comparable or improved properties to bare PDMS.

Abstract
Catheter-associated urinary tract infection (CAUTI) is defined as a urinary tract infection associated with catheter placement for more than two consecutive days. Hence, antibiotic resistance in the context of CAUTIs represents a substantial challenge. The aim of this study was to present the characteristics of patients with CAUTI and the susceptibility pattern of CAUTI bacteria in the national reference hospital of the Sumatra region of Indonesia. A cross-sectional study was conducted at H. Adam Malik General Hospital, Medan, Indonesia, from 2020 to 2021, using a total sampling. All CAUTI patients included were on catheterization and diagnosed based on the Centers for Disease Control and Prevention (CDC) guidelines. The patient's urine culture and antibiotic susceptibility test were carried out on the patient's admitted urine sample for further assessment. Identification of bacteria, antibiotic susceptibility test, and the extended-spectrum beta-lactamase (ESBL) test for Escherichia coli and Klebsiella pneumoniae were conducted using the VITEK-2 Compact. A total of 74 CAUTI patients were included in the study, 59.5% were female, 54.1% were 46-65 years old, and a third had cardiovascular disease comorbidities (33.8%). A total of 83 CAUTI-associated bacteria were isolated. The majority were Gram-negative bacteria (74.7%), and the most bacteria isolated was E. coli (31.3%), followed by K. pneumoniae, Enterococcus faecalis, Acinetobacter baumannii, and Enterococcus faecium. The ESBL test was positive mostly in K. pneumoniae (100%) and E. coli (76.9%). CAUTI-associated E. coli was susceptible to tigecycline, meropenem, ertapenem, nitrofurantoin, and gentamicin. The isolated K. pneumoniae was susceptible to tigecycline, meropenem, ertapenem, and amikacin. While E. faecalis showed susceptibility to tigecycline, nitrofurantoin, vancomycin, imipenem, linezolid, ampicillin, piperacillin/tazobactam, amoxicillin/clavulanic acid, ampicillin/sulbactam, and piperacillin.

Abstract
Introduction Because the risk of health-care associated infections (HAIs) is high in intensive care units, and HAIs are one of the causes of morbidity and mortality and affects the overall quality of health care, the continuous monitoring of HAIs in intensive care patients is essential. Aim and objectives This descriptive cross-sectional study was carried out over a period of five years in a tertiary-care teaching hospital. The aim of the study was to investigate the main and specific types of health-care associated Infections and determine the microbiological profile and antimicrobial susceptibility rates of isolates in patients with HAI. Methods : The active surveillance method was used to detect HAIs in patients who spent over 48 hr in a targeted ICU. Patients with blood stream infections (BSI), central line-associated bloodstream infection (CLABSI), catheter-associated urinary tract infections (CAUTI) and ventilator-associated events (VAE) were included in the study. HAI were diagnosed based on the Centre for Disease Control (CDC)'s National Healthcare Safety Network (NHSN) updated definitions of HAIs. Results A total of 121,051 patient days, including 7,989 central line days, 64,557 urinary catheter days, and 18,443 ventilator days, were recorded in the study population and 832 HAIs were diagnosed (incidence rate 6.9%). The overall rates of BSI, CLABSI, CAUTI and possible ventilator-associated pneumonia (p-VAP) were 3.7, 10.6, 2.1 and 13.4/1,000 device days, respectively. The most common organism isolated from BSI was Acinetobacter baumanii (n=322, 29%), followed by Klebsiella pneumoniae 225 (n=225, 20.3%). 79.8% of Acinetobacter baumanii strains were resistant to imipenem, 77.1% to ciprofloxacin and 76.4% to ampicillin. The most common organisms isolated from CAUTI were non-albicans Candida species (n=38, 18%), followed by E. coli and Citrobacter spp. (each n=33, each 15.7%). Conclusions A trend of increasing resistance of Acinetobacter baumannii to carbapenems was observed. Risk factor analysis showed invasive procedures during sepsis and organophosphorous poisoning as significant factors.

Abstract
OBJECTIVES This study examined the association between safety attitudes, quality of care, missed care, nurse staffing levels, and the rate of healthcare-associated infection (HAI) in adult intensive care units (ICUs). METHODS A cross-sectional study was conducted in five hospitals. Nurses completed a validated survey on safety attitudes, quality of care, missed care, nurse staffing levels, and the frequency of HAIs. Secondary data were collected on the incidence of central line-associated bloodstream infection (CLABSI), catheter-associated urinary tract infection (CAUTI), and ventilator-associated pneumonia (VAP) in participating units. Descriptive analysis and generalized linear models were performed. RESULTS A total of 314 nurses from eight ICUs participated in this study. The mean safety culture score was 60.85 (SD = 3.53). ICUs with strong job satisfaction had lower incidence and nurse-reported frequency of CLABSI, CAUTI, and VAP. Missed care was common, with 73.11% of nurses reporting missing at least one required care activity on their last shift. The mean patient-to-nurse ratio was 1.95. Increased missed care and higher workload were associated with higher HAIs. Nurses' perceptions of CLABSI and VAP frequency were positively associated with the actual occurrence of CLABSI and VAP in participating units. CONCLUSION Positive safety culture and better nurse staffing levels can lower the rates of HAIs in ICUs. Improvements to nurse staffing will reduce nursing workloads, which may reduce missed care, increase job satisfaction, and, ultimately, reduce HAIs. IMPLICATIONS FOR CLINICAL PRACTICE Higher levels of job satisfaction among ICU nurses, lower proportions of missed nursing care and higher nurse staffing are associated with lower rates of HAIs. Nurse-reported HAI frequency was positively associated with the incidence of HAIs; therefore, nurses provide reliable data on infection control outcomes in ICU settings.

Abstract
Catheter-associated urinary tract infections (CAUTIs) are amongst the most common nosocomial infections worldwide and are difficult to treat due to multi-drug resistance development among the CAUTI-related pathogens. Importantly, CAUTI often leads to secondary bloodstream infections and death. A major challenge is to predict when patients will develop CAUTIs and which populations are at-risk for bloodstream infections. Catheter-induced inflammation promotes fibrinogen (Fg) and fibrin accumulation in the bladder which are exploited as a biofilm formation platform by CAUTI pathogens. Using our established mouse model of CAUTI, we identified that host populations exhibiting either genetic or acquired fibrinolytic-deficiencies, inducing fibrin deposition in the catheterized bladder, are predisposed to severe CAUTI and septicemia by diverse uropathogens in mono- and poly-microbial infections. Furthermore, we found that E. faecalis, a prevalent CAUTI pathogen, uses the secreted protease, SprE, to induce fibrin accumulation and create a niche ideal for growth, biofilm formation, and persistence during CAUTI.

Abstract
Proteus mirabilis is an opportunistic pathogen and is responsible for more than 40% of all cases of catheter-associated urinary tract infections (CAUTIs). Healthcare-associated infections have been aggravated by the constant emergence of antibiotic-resistant bacterial strains. Because of this, the use of phages to combat bacterial infections gained renewed interest. In this study, we describe the biological and genomic features of two P. mirabilis phages, named BigMira and MidiMira. These phages belong to the Acadevirus genus (family Autographiviridae). BigMira and MidiMira are highly similar, differing only in four missense mutations in their phage tail fiber. These mutations are sufficient to impact the phages' depolymerase activity. Subsequently, the comparative genomic analysis of ten clinical P. mirabilis strains revealed differences in their antibiotic resistance profiles and lipopolysaccharide locus, with the latter potentially explaining the host range data of the phages. The massive presence of antimicrobial resistance genes, especially in the phages' isolation strain P. mirabilis MCS, highlights the challenges in treating infections caused by multidrug-resistant bacteria. The findings reinforce BigMira and MidiMira phages as candidates for phage therapy purposes.

Abstract
INTRODUCTION Catheter-associated urinary tract infection (CAUTI) is the most common healthcare-associated infection which tends to cause increased length of morbidity, and mortality of patients, in addition to increased bacterial resistance to antibiotics. METHODOLOGY In the present study, urinary catheters were collected from a 50-year-old woman suffering from malignancy, bedridden, and having urinary incontinence. These catheters were processed in laboratory for isolation of bacteria using standard procedures. RESULTS Microbiological examination of the urinary catheters by biochemical, physiological, and VITEK 2 compact system revealed bacterial infection caused by Micrococcus lylae, a Gram-positive microorganism belonging to the family Micrococcacea. These Gram-positive bacteria were found to be susceptible to streptomycin, erythromycin, cefotaxime, neomycin, kanamycin, vancomycin, azithromycin, chloramphenicol, and tetracycline. Bacterial species were confirmed using 16s rRNA sequencing. CONCLUSIONS The sequences were found to have 99% similarity with Micrococcus lylae. This is the first report of isolation of Micrococcus lylae from the urinary catheter.

Abstract
BACKGROUND Urinary tract infections (UTIs) are one of the most common hospital-acquired complications. Insertion of a urinary catheter and the duration of catheterization are the main risk factors, with catheter-associated UTIs (CAUTIs) accounting for 70-80% of hospital-acquired UTIs. Guidance is available regarding the prevention of hospital-acquired CAUTIs; however, how best to operationalize this guidance remains a challenge. AIM To map and summarize the peer-reviewed literature on model-of-care interventions for the prevention of CAUTIs in adult inpatients. METHODS PubMed, CINAHL and SCOPUS were searched for articles that reported UTI, CAUTI or urinary catheter outcomes. Articles were screened systematically, data were extracted systematically, and interventions were classified by intervention type. FINDINGS This review included 70 articles. Interventions were classified as single component (N=19) or multi-component (N=51). Single component interventions included: daily rounds or activities (N=4), protocols and procedure changes (N=6), reminders and order sets (N=5), audit and feedback interventions (N=3), and education with simulation (N=1). Overall, daily catheter reviews and protocol and procedure changes demonstrated the most consistent effects on catheter and CAUTI outcomes. The components of multi-component interventions were categorized to map common elements and identify novel ideas. CONCLUSION A range of potential intervention options with evidence of a positive effect on catheter and CAUTI outcomes was identified. This is intended to provide a 'menu' of intervention options for local decision makers, enabling them to identify interventions that are relevant and feasible in their local setting.

Abstract
BACKGROUND Bladder catheterization is a common medical manipulation that is associated with the risk of complications, including catheter-associated urinary tract infection (CAUTI), which accounts for 80% of all nosocomial infections of the urological profile. AIM To evaluate the combined use of the biologically active additive Uronext and ceftriaxone in the prevention of the development of CAUTI in the early postoperative period in 120 patients aged 20-80 years with a Foley indwelling catheter. MATERIALS AND METHODS The patients were divided into 2 groups: in group I (n=60), D-mannose with cranberry extract and vitamin D3 as part of Uronext dietary supplement was administered orally in the form of sachets 48 hours before surgery and after surgery until urethral catheter was placed, as well as intravenous ceftriaxone 1000 mg 2 hours before surgery and in the postoperative period within 7 days. In group II (n=60), ceftriaxone monotherapy was prescribed in a similar way. RESULTS According to the results of bacteriological examination of the removed urinary catheter on 3-7 days in Uronext group, bacterial growth was absent in 40 patients (66.67%, p<0.05), versus 23 cases (38.33%) in the control group. CONCLUSIONS The data obtained confirm the efficiency of the use of the biologically active additive Uronext in combination with an antibacterial drug, which allows to recommend this scheme in patients with an indwelling urinary catheter for the prevention of the development of CAUTI.

Abstract
Polymicrobial biofilms play an important role in the development and pathogenesis of CAUTI. Proteus mirabilis and Enterococcus faecalis are common CAUTI pathogens that persistently co-colonize the catheterized urinary tract and form biofilms with increased biomass and antibiotic resistance. In this study, we uncover the metabolic interplay that drives biofilm enhancement and examine the contribution to CAUTI severity. Through compositional and proteomic biofilm analyses, we determined that the increase in biofilm biomass stems from an increase in the protein fraction of the polymicrobial biofilm matrix. We further observed an enrichment in proteins associated with ornithine and arginine metabolism in polymicrobial biofilms compared to single-species biofilms. We show that L-ornithine secretion by E. faecalis promotes arginine biosynthesis in P. mirabilis, and that disruption of this metabolic interplay abrogates the biofilm enhancement we see in vitro and leads to significant decreases in infection severity and dissemination in a murine CAUTI model.

Abstract
BACKGROUND Device-associated infections (DAIs) are important components of healthcare associated infection and are associated with increased morbidity and mortality. This study describes DAIs across different intensive care units (ICUs) in a hospital in Saudi Arabia. METHODS The study was conducted between 2017 and 2020 and followed the definitions of National Healthcare Safety Network (NHSN) for DAIs. The calculated the rates of ventilator-associated events (VAE), catheter-associated urinary tract infections (CAUTI) and central line-associated blood stream infections (CLABSI) followed NHSN definitions. RESULTS During the study period, there were 82 DAIs in adult ICUs and of these 16 (19.5%) were CLABSI, 26 (31.7%) were CAUTI and 40 (48.7%) were VAE. The overall rates for adult ICUs were 1.6, 1.9, 3.8 per 1000 device-days for CAUTI, CLABSI and VAE, respectively. The device-utilization ratio was 0.5, 0.6, and 0.48 for urinary catheters, central lines, and ventilators, respectively. VAE rates for medical and surgical ICU were about 2.8 times the rate in the coronary care unit and the rates were high in 2020 corresponding with the COVID-19 pandemic. Of the adult ICUS, medical ICU had a CLABSI rate of 2.13/1000 device-days and was about double the rate in surgical and cardiac ICU. For CAUTI, the rates per 1000 device-days were 2.19, 1.73, and 1.65 for medical, surgical, and coronary ICUs, respectively. The rate of CLABSI per 1000 device-days for pediatric and neonatal ICUs were 3.38 and 2.28, respectively. CONCLUSIONS CAUTI was the most common infections among adult ICUs and medical ICU had higher rates than other adult ICUs. VAE rate was higher in the first year of the COVID-19 pandemic, indicating increased device-use, change in patients characteristics as well as possible change in practices across the ICUs.

Abstract
<b>Background and Objective:</b> Biofilms as a bacterial defense are relatively more difficult to eradicate with antibiotics, thus pathogenic bacteria in their biofilm form can cause serious problems for human health. Lakum <i>(Causonis trifolia</i> L.) is an herbaceous plant with many biological activities, one of which is an antimicrobial compound containing flavonoids, squalene, nimbidin, saponins, anthocyanins, tannins, myricetin, others. This study aimed to determine the antibiofilm activity of Lakum leaf extract against<i> Staphylococcus aureus </i>bacteria and the active compounds that play a role in inhibiting monomicrobial biofilms. <b>Materials and Methods:</b> This research method was carried out with an <i>in vitro</i> experimental study design using observations of phytochemical screening test results and the effectiveness of Lakum leaf antibiofilm on<i> Staphylococcus aureus</i> through microplate reader readings that measure optical density values. <b>Results:</b> This study showed that Lakum leaves contain alkaloids, flavonoids, phenolics, polyphenols, tannins and saponins. In addition, Lakum leaves gave biofilm inhibitory activity in the middle and maturation phase with the highest concentration in 1% extract of 76.95±0.0007 and 72.85± 0.0003%, respectively. Meanwhile, the lowest concentration was 0.125% extract of 65.65±0.0001% in the middle phase and 59.71±0.0003% in the maturation phase. <b>Conclusion:</b> That Lakum leaves have biofilm inhibitory activity on <i>Staphylococcus aureus</i> with flavonoid compounds, tannins and polyphenols that work as active substances in inhibiting the biofilm formation.

Abstract
Biofilms are often polymicrobial in nature, which can impact their behavior and overall structure, often resulting in an increase in biomass and enhanced antimicrobial resistance. Using plate counts and locked nucleic acid/2'-O-methyl-RNA fluorescence in situ hybridization (LNA/2'OMe-FISH), we studied the interactions of four species commonly associated with catheter-associated urinary tract infections (CAUTI): Enterococcus faecalis, Escherichia coli, Candida albicans, and Proteus mirabilis. Eleven combinations of biofilms were grown on silicone coupons placed in 24-well plates for 24 h, 37°C, in artificial urine medium (AUM). Results showed that P. mirabilis was the dominant species and was able to inhibit both E. coli and C. albicans growth. In the absence of P. mirabilis, an antagonistic relationship between E. coli and C. albicans was observed, with the former being dominant. E. faecalis growth was not affected in any combination, showing a more mutualistic relationship with the other species. Imaging results correlated with the plate count data and provided visual verification of species undetected using the viable plate count. Moreover, the three bacterial species showed overall good repeatability SD (Sr ) values (0.1-0.54) in all combinations tested, whereas C. albicans had higher repeatability Sr values (0.36-1.18). The study showed the complexity of early-stage interactions in polymicrobial biofilms. These interactions could serve as a starting point when considering targets for preventing or treating CAUTI biofilms containing these species.

Abstract
Healthcare-associated infections are major causes of complications that lead to extended hospital stays and significant medical costs. The use of medical devices, including catheters, increases the risk of bacterial colonization and infection through the presence of a foreign surface. Two outcomes are observed for catheterized patients: catheter-associated asymptomatic bacteriuria and catheter-associated urinary tract infection (CAUTI). However, the relationship between these two events remains unclear. To understand this relationship, we studied a murine model of Pseudomonas aeruginosa CAUTI. In this model, we also observe two outcomes in infected animals: acute symptoms that is associated with CAUTI and chronic colonization that is associated with asymptomatic bacteriuria. The timing of the acute outcome takes place in the first week of infection, whereas chronic colonization occurs in the second week of infection. We further showed that mutants lacking genes encoding type III secretion system (T3SS), T3SS effector proteins, T3SS injection pore, or T3SS transcriptional activation all fail to cause acute symptoms of CAUTI. Nonetheless, all mutants defective for T3SS colonized the catheter and bladders at levels similar to the parental strain. In contrast, through induction of the T3SS master regulator ExsA, all infected animals showed acute phenotypes with bacteremia. Our results demonstrated that the acute symptoms, which are analogous to CAUTI, and chronic colonization, which is analogous to asymptomatic bacteriuria, are independent events that require distinct bacterial virulence factors. Experimental delineation of asymptomatic bacteriuria and CAUTI informs different strategies for the treatment and intervention of device-associated infections.

Abstract
BACKGROUND We instituted Kamishibai (K-card rounding) with the goals of improving indwelling urinary catheter maintenance bundle reliability and decreasing catheter-associated urinary tract infection (CAUTI) rates. METHOD In a free-standing children's hospital, we undertook a hospital-wide quality improvement project from January 2019 to June 2021 after developing a K-card based on our urinary catheter maintenance bundle. Auditors used K-cards to ask standardized questions during weekly rounds. Bundle reliability and CAUTI rates were analyzed prospectively. RESULTS During the study period, 826 K-card audits were performed for 657 unique patients. While overall maintenance bundle reliability remained stable at 84%, there was a statistically significant improvement in reliability to the bundle element "medical discussion of need for the urinary catheter" from 88% to 94% (P = .01). The hospital-wide CAUTI rate significantly decreased (incidence rate ratio, 0.38; 95% CI, 0.15-0.93; P = .04). DISCUSSION Hospital-wide urinary catheter K-card rounding facilitated standardized data collection, discussion of reliability and real-time feedback to nurses. Maintenance bundle reliability remained stable after implementation, accompanied by a significant decrease in the CAUTI rate. CONCLUSIONS Implementation of hospital-wide urinary catheter K-card rounding was associated with reduction in CAUTI rates. The project demonstrated likelihood of reproducibility with support of a multidisciplinary team.

Abstract
Objective: A quality improvement study to assess catheter-associated urinary tract infection (CAUTI) rate post-implementation of a bladder catheter with integrated active drain line urine clearance and automated intra-abdominal pressure monitoring in a burn intensive care unit (ICU). DESIGN: Eight-year retrospective before and after study (2015−2022). Setting: A single American Burn Association-verified Burn Center with 14 inpatient beds. Patients: Patients meeting criteria for admission to a Burn Center. Methods: Retrospective cohort study following the implementation of a novel urine output monitoring system with integrated drain line and urine clearance. Data from a 48-month (from January 2015−December 2018) historical control (period 1) were compared to data from a 28-month (from January 2020 to April 2022) post-implementation period (period 2). Pre- and post-implementation CAUTI event incidences were compared. Patients were transferred from outside hospitals with gravity bladder. A distinction in the chart between catheter types was impossible. Charts were reviewed to characterize patients with CAUTI events. Results: A total of 42 CAUTIs in 2243 patients were identified using the National Health and Safety Network (NHSN) definition during the analyzed period. There were 40 CAUTI events in period 1 and two CAUTIs in period 2. The incidence of CAUTI events pre-implementation was 0.030 (mean of 10 CAUTI events per year) compared to 0.002 (mean of 1 CAUTI event per year) post-implementation of an automatic drain line clearing UO monitoring system showing a significant reduction in CAUTI events (p < 0.01, risk ratio novel vs. gravity bladder catheter 0.071, 95% confidence interval: 0.017−0.294). Conclusions: CAUTIs were reduced in the period following the implementation of a novel urinary catheter system with an integrated active drain line and urine clearance in burn patients.

Abstract
In recent years, we have witnessed prominent improvements in urinary catheter coatings to tackle the commonly occurring catheter-associated urinary tract infection (CAUTI) in catheterized patients. CAUTIs are claimed to be one of the most frequent nosocomial infections that can lead to various complications, from catheter encrustation to severe septicaemia and pyelonephritis. Besides general prevention hygienic strategies, antimicrobial-coated urinary catheters show great potential in the prevention of urinary catheter-associated complications. The aim of this review is to present and evaluate recent updates on the development of antimicrobial urinary catheters in the context of the aetiology of urinary malfunction. Subsequently, we shed some light on future perspectives of utilizing 3D printing and the surrounding regulatory directions.

Abstract
BACKGROUND The coronavirus disease 2019 (COVID-19) pandemic had a considerable impact on US healthcare systems, straining hospital resources, staff, and operations. However, a comprehensive assessment of the impact on healthcare-associated infections (HAIs) across different hospitals with varying level of infectious disease (ID) physician expertise, resources, and infrastructure is lacking. METHODS This retrospective longitudinal multicenter cohort study included central-line-associated bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTIs), Clostridioides difficile infections (CDIs), and ventilator-associated events (VAEs) from 53 hospitals (academic and community) in Southeastern United States from 1 January 2018 to 31 March 2021. Segmented negative binomial regression generalized estimating equations models estimated changes in monthly incidence rates in the baseline (01/2018-02/2020) compared to the pandemic period (03/2020-03/2021, further divided into three pandemic phases). RESULTS CLABSIs and VAEs increased by 24% and 34%, respectively, during the pandemic period. VAEs increased in all phases of the pandemic, while CLABSIs increased in later phases of the pandemic. CDI trend increased by 4.2% per month in the pandemic period. On stratifying the analysis by hospital characteristics, the impact of the pandemic on healthcare-associated infections was more significant in smaller sized and community hospitals. CAUTIs did not change significantly during the pandemic across all hospital types. CONCLUSIONS CLABSIs, VAEs, and CDIs increased significantly during the pandemic, especially in smaller community hospitals, most of which lack ID physician expertise. Future efforts should focus on better understanding challenges faced by community hospitals, strengthening the infection prevention infrastructure, and expanding the ID workforce, particularly to community hospitals.

Abstract
While there are established and effective guidelines for prevention of hospital-acquired infections (HAIs), the impact of the COVID-19 pandemic on those implemented practices and policies have not been thoroughly investigated. This report examines the impact of COVID-19 on HAI rates at 2 hospitals within the same healthcare system. HAIs significantly increased during the COVID-19 pandemic which correlated with the use of overtime and agency nursing hours.

Abstract
BACKGROUND The Centers for Disease Control and Prevention reports that catheter-associated urinary tract infections (CAUTIs) are the most common hospital-acquired infection. Female external urinary collection devices (EUCDs) may be an alternative to indwelling urethral catheters (IUCs), thereby decreasing CAUTIs. However, no study has demonstrated that EUCDs can help reduce CAUTIs in female surgical patients. We sought to compare CAUTI rate and the median number of days an IUC was used before and after availability of this female EUCD for surgical patients. METHODS A retrospective analysis of adult female surgical patients admitted to a single academic institution who received an IUC and/or EUCD was performed. Patients who received an IUC three months before (PRE) EUCD availability (08/2017-10/2017) were compared to patients receiving an IUC and/or EUCD 12 months after (POST) (11/2017-11/2018). RESULTS From 906 surgical patients receiving an IUC/EUCD, 127 received an EUCD in the POST cohort. Compared to the PRE, the POST had a higher rate of CAUTIs (infections per 1000 catheter days, 11.2 vs. 4.6, p = 0.017) and overall UTI rate (infections per 1000 catheter days, 5.4 vs. 4.8, p = 0.036), whereas IUC days were similar between cohorts (median, two vs. two days, p = 0.18). The POST cohort rate of EUCD UTI was 4.6 infections per 1000 device days. CONCLUSION While EUCDs appear to be a promising alternative to IUCs for female surgical patients, this study found increased CAUTIs after introduction of an EUCD. Further research is needed to clarify if female EUCDs are effective in decreasing CAUTI prior to widespread adoption.

Abstract
New, contextualized modern solutions must be found to solve the dilemma of catheter-associated urinary infection (CAUTI) in long-term care settings. In this paper, we describe the etiology, risk factors, and complications of CAUTI, explore different preventive strategies proposed in literature from the past to the present, and offer new insights on therapeutic opportunities. A care bundle to prevent CAUTI mainly consists of multiple interventions to improve clinical indications, identifying a timeline for catheter removal, or whether any alternatives may be offered in elderly and frail patients suffering from chronic urinary retention and/or untreatable urinary incontinence. Among the various approaches used to prevent CAUTI, specific urinary catheter coatings according to their antifouling and/or biocidal properties have been widely investigated. Nonetheless, an ideal catheter offering holistic antimicrobial effectiveness is still far from being available. After pioneering research in favor of bladder irrigations or endovesical instillations was initially published more than 50 years ago, only recently has it been made clear that evidence supporting their use to treat symptomatic CAUTI and prevent complications is needed.

Abstract
Catheter-associated urinary tract infections (CAUTI) are a common clinical concern as they can lead to severe, persistent infections or bacteremia in long-term catheterized patients. This type of CAUTI is difficult to eradicate, as they are caused by multispecies biofilms that may have reduced susceptibility to antibiotics. Many new strategies to tackle CAUTI have been proposed in the past decade, including antibiotic combination treatments, surface modification and probiotic usage. However, those strategies were mainly assessed on mono- or dual-species biofilms that hardly represent the long-term CAUTI cases where, normally, 2–4 or even more species can be involved. We developed a four-species in vitro biofilm model on catheters involving clinical strains of Escherichia coli, Pseudomonas aeruginosa, Klebsiella oxytoca and Proteus mirabilis isolated from indwelling catheters. Interspecies interactions and responses to antibiotics were quantitatively assessed. Collaborative as well as competitive interactions were found among members in our model biofilm and those interactions affected the individual species’ abundances upon exposure to antibiotics as mono-, dual- or multispecies biofilms. Our study shows complex interactions between species during the assessment of CAUTI control strategies for biofilms and highlights the necessity of evaluating treatment and control regimes in a multispecies setting.

Abstract
OBJECTIVE We aim to evaluate the role of frailty and inflammatory markers in predicting the short-term outcomes after catheter-associated urinary tract infections (CAUTI) and central line-associated bloodstream infections (CLABSI). METHODS Data regarding the patients' characteristics, isolates on CAUTI and CLABSI, antibiotic susceptibility, frailty (11-point Modified Frailty Index), and inflammatory markers were retrospectively collected. Their impact on the short-term outcomes was assessed using regression modeling response. RESULTS One hundred and one patients with CAUTI (n = 71) and CLABSI (n = 30) between January 2018 and December 2019 were included in this study. The pooled incidence rates for CAUTI were 5.50 and for CLABSI 3.58 episodes/1000 catheter-days. We observed 74.7% drug resistance in our CAUTI isolates and 93.3% in CLABSI. In the multivariate analysis, frailty (P = 0.006), neutrophil/lymphocyte ratio (NLR) (P = 0.007) and the presence of sepsis (P = 0.029) were found to be significant predictors of in-hospital mortality in CAUTI. In patients with CLABSI, frailty (P = 0.029) and NLR (P = 0.029) were found significant and along with sepsis (P = 0.069) resulted in a regression model with good accuracy in predicting mortality. The receiver operating characteristic curve showed that 11-point Modified Frailty Index and NLR as well as the regression model significantly predicted mortality with an area under the curve of 86.1%, 81.4%, and 95.4%, respectively, in CAUTI, and 70.9%, 77.8%, and 95.2%, respectively, in CLABSI.

Abstract
High rates of antimicrobial resistance and formation of biofilms makes treatment of Escherichia coli catheter-associated urinary tract infections (CAUTI) particularly challenging. CAUTI affect 1 million patients per year in the United States and are associated with morbidity and mortality, particularly as an etiology for sepsis. Phage have been proposed as a potential therapeutic option. Here, we report the development of phage cocktails that lyse contemporary E. coli strains isolated from the urine of patients with spinal cord injury (SCI) and display strong biofilm-forming properties. We characterized E. coli phage against biofilms in two in vitro CAUTI models. Biofilm viability was measured by an MTT assay that determines cell metabolic activity and by quantification of colony forming units. Nine phage decreased cell viability by >80% when added individually to biofilms of two E. coli strains in human urine. A phage cocktail comprising six phage lyses 82% of the strains in our E. coli library and is highly effective against young and old biofilms and against biofilms on silicon catheter materials. Using antibiotics together with our phage cocktail prevented or decreased emergence of E. coli resistant to phage in human urine. We created an anti-biofilm phage cocktail with broad host range against E. coli strains isolated from urine. These phage cocktails may have therapeutic potential against CAUTI.

Abstract
BACKGROUND Surgeons use indwelling bladder catheters (IBCs) to avoid urinary retention in patients with epidural analgesic catheters. Reduction of IBC-days is associated with improved catheter-associated urinary tract infection rates (CAUTI). This study investigates real world application of a Nurse-Driven Catheter Removal Protocol (NDCRP) to reduce IBC-days in this patient population. METHODS Patients with epidural catheters and IBC were targeted for IBC removal on post-operative day 1 (POD1). Patients were followed for application of the NDCRP, catheterization need, IBC re-anchoring, and complications. RESULTS One hundred and thirty-three patients had IBCs removed on POD1 (Protocol Group) and 50 patients did not (Non-Protocol Group). There was a reduction in IBC-days in the Protocol Group despite incomplete adherence to the NDCRP (1.55 days vs 4.64 days; P < .001). Ninety-three patients (70%) were able to spontaneously void after early IBC removal. Fourteen patients (11%) were able to spontaneously void after serial in-and-out catheterization (I/O). No significant difference in re-anchoring was found between the protocol and non-protocol groups (26 vs 4 patients; P = .09). CONCLUSIONS Early removal of IBCs (POD1) in patients with epidural catheters with the assistance of an NDCRP is a safe and successful strategy to reduce IBC-days in the hospital.

Abstract
The SARS-CoV-2 pandemic might have increased the risks of healthcare-associated infections (HAIs); however, several studies of HAI such as urinary tract infections (UTIs) and catheter-associated urinary tract infections (CAUTIs) have shown contradictory results. The aim of this study is to assess the clinical features of UTIs and bacterial isolates from urine samples of hospitalized COVID-19 patients. We conducted a retrospective observational study including 87 COVID-19 patients with UTIs admitted to our centre. Bacterial UTIs presented were 87: 9 (10.3%) community-acquired UTIs (coinfection group) and 78 (89.6%) hospital-acquired UTIs (superinfection group). In the coinfection group, the most frequent type was non-CAUTI with 5 (55.5%) patients; however, the most frequent UTI in the superinfection group was CAUTI, with 53 (67.9%) patients. The median number of days of hospitalization in coinfected patients was lower than superinfection patients: 13 (IQR 11, 23) vs. 34 days (IQR 23, 47) p < 0.006. All UTI patients admitted to ICU, 38 (43.7%), belonged to the superinfection group. The mortality rate was 26.4% (23/87), 22/23 in the superinfection group. The most common microorganisms were E. coli 27 (28.4%), E. faecalis 25 (26.3%) and E. faecium 20 (21.1%). There was an increased incidence of E. faecalis and E. faecium in UTIs as well as hospital-acquired UTIs. This can be related to urethral catheterization during hospitalization, UCI admissions and the number of days of hospitalization.

Abstract
In every age group, urinary tract infection (UTI) is found as a major recurrence infectious disorder. Bio-films produced by bacteria perform a vital role in causing infection in the tract of the urinary system, leading to recurrences and relapses. The purpose of this review is to present the role and mechanism of bio-film producing MDR Gram-negative bacteria causing UTI, their significance, additionally the challenges for remedy and prevention of catheter-associated UTI. This work appreciates a new understanding of bio-film producers which are having multi-drug resistance capability and focuses on the effect and control of bio-film producing uropathogenic bacteria related to catheterization. We have tried to analyze approaches to target bio-film and reported phytochemicals with anti-bio-film activity also updated on anti-bio-film therapy.

Abstract
Catheter-associated urinary tract infections resulting from urease-positive microorganisms are more likely to cause a urinary catheter blockage owing to the urease activity of the microbes. Catheter blockage can be dangerous and increases the risk of severe infections, such as sepsis. Ureases, a virulence factor in Proteus mirabilis, cause an increase in urine pH - leading to blockage. An optimised biosensor "lozenge" is presented here, which is able to detect impending catheter blockage. This lozenge has been optimised to allow easy manufacture and commercialisation. It functions as a sensor in a physiologically representative model of a catheterised urinary tract, providing 6.7 h warning prior to catheter blockage. The lozenge is stable in healthy human urine and can be sterilized for clinical use by ethylene oxide. Clinically, the lozenge will provide a visible indication of impending catheter blockage, enabling quicker clinical intervention and thus reducing the morbidity and mortality associated with blockage.

Abstract
Previous studies indicate variability in the accurate application of National Healthcare Safety Network surveillance criteria with limited data on possible contributing factors. In this cross-sectional, convenience sampled web-based survey sent to members of Texas infection prevention and control organizations, training, experience, and time spent on surveillance was collected and assessed including 2 case studies. Our results indicate correct identification of catheter-associated urinary tract infection (CAUTI) and central line-associated bloodstream infection (CLABSI) criteria may be associated with 2019 National Healthcare Safety Network training (CAUTI: aOR = 0.17, 95% CI: 0.04, 0.80; CLABSI: aOR = 0.45, 95% CI: 0.045, 4.56) and increased years of infection prevention experience (CAUTI: aOR = 1.35, 95% CI: 0.42, 4.33; CLABSI: aOR = 1.23, 95% CI: 0.24, 6.38). Routinely performing more hours of surveillance may increase accuracy of CLABSI identification, but not CAUTI.

Abstract
Urinary infections related to the presence of bacterial biofilm on catheters are responsible for loss of patients’ health and, due to their high frequency of occurrence, generate a significant economic burden for hospitals. Klebsiella pneumoniae is a pathogen frequently isolated from this type of infection. In this study, using a cohesive set of techniques performed under stationary and flow conditions, we assessed the ability of 120 K. pneumoniae strains to form biofilm on various surfaces, including catheters, and evaluated the usefulness of clinically applied and experimental compounds to remove biofilm. The results of our study indicate the high impact of intraspecies variability with respect to K. pneumoniae biofilm formation and its susceptibility to antimicrobials and revealed the crucial role of mechanical flushing out of the biofilm from the catheter’s surface with use of locally active antimicrobials. Therefore, our work, although of in vitro character, may be considered an important step in the direction of efficient reduction of K. pneumoniae biofilm-related hospital infections associated with the presence of urine catheters.

Abstract
Introduction: Hospital-acquired infection (HAI) rates were reported to have declined in healthcare settings during the Covid-19 pandemic. Needless to mention that HAI is of paramount interest and relevance to a primary care physician who need to care from womb to tomb inside pandemic. Objectives: This study was conducted to find the impact of Covid-19 pandemic on the four parameters of HAIs, namely, catheter-associated urinary tract infections (CAUTI), central-line-associated bloodstream infections (CLABSI), ventilator-associated pneumonia (VAP) and surgical site infections (SSIs) with hand hygiene compliance rates among healthcare workers. Materials and Methods: This retrospective data mining was undertaken in a 700 bed multispecialty teaching hospital in the Eastern India which was a Government of Bihar approved speciality Covid Care Hospital. Data from the monthly routine infection control monitoring and surveillance activities was collated from January 2019 to December 2020. Control charts with upper and lower control limit set at mean ± 1 SD were used to monitor monthly trends of HAIs. Results: The CAUTI rates reduced by 28.01%; the CLABSI rates declined by 37.61%, the SSI rates reduced by 62.39%, while the highest VAP rates were reported in November 2019 (1.9 per 1000 ventilator days). The hand hygiene compliance rates from January 2019 to December 2020 among different healthcare staffs showed a sharply rising trend. Conclusion: Covid-19 pandemic highlighted paramount importance regarding compliance to hand hygiene and implementation of standard infection control practices as recommended by World Health Organisation and Centres for Diseases Control and Prevention (CDC), which can drastically reduce range of HAIs.

Abstract
BACKGROUND When traditional interventions are used in long term care for catheter associated urinary tract infection (CAUTI) prevention, residual rates are still high despite a decrease. We conducted a quality improvement study focusing our interventions on patient and staff behavioral patterns identified through a structured huddle process to improve upon the basics for CAUTI prevention. METHODS Baseline was from January 2016 to March 2017; the intervention period was from April 2017 to June 2020. We implemented a systematic huddle to determine root cause of each CAUTI and applied lessons throughout the facility. We measured the monthly CAUTI incidence per 1000 urinary catheter days and analyzed the reduction in CAUTI during the intervention period. RESULTS CAUTI decreased by 73% during the intervention period compared to the baseline period, with an IRR of 0.27 (95% confidence interval [CI]: 0.11-0.66; P = .004). The number of catheter days per month increased by 4% in the intervention period (17,407 in 39 months) compared to the baseline period (6,440 in 15 months) with IRR of 1.04 (95% confidence interval [CI]: 1.01-1.07; P = .008). No patterns were noted in organisms responsible for CAUTI. CONCLUSIONS Our findings stress the importance of looking beyond the traditional interventions for CAUTI prevention in long term care population. By doing this, interventions can be customized for this special population to achieve optimal outcomes.

Abstract
PURPOSE Characterization of different uropathogenic E. coli (UPEC) phylogroups is crucial to understand pathogenesis of urinary tract infection (UTI). The objective of our study was to evaluate the antibiotic resistance pattern, biofilm formation and pathogenicity islands (PAIs) of UPEC phylogroups isolated from catheter-associated UTI (CAUTI) compared to community UTI (Com-UTI). PATIENTS AND METHODS This study included 90 UPEC strains recovered from CAUTI and Com-UTI. Antimicrobial susceptibility was tested by the Kirby-Bauer method and extended spectrum beta-lactamase (ESBL) production was confirmed using the combined disk. The biofilm formation was tested using the microtiter plate assay. Main E. coli phylogroups (A, B1, B2 and D) were detected by multiplex PCR and 2 multiplex PCR detected the 8 PAIs. RESULTS Antibiotic resistance of UPEC strains showed a similar high resistance in CAUTI and Com-UTI. Isolates from CAUTI significantly produced biofilm higher than Com-UTI strains (68.9% vs 44.4%). In CAUTI and Com-UTI isolates, phylogroup A was the commonest (53.3% vs 48.9%, respectively). PAI IV536 was the most common in the strains from CAUTI (71.1%) and Com-UTI (73.3%). No significant relationship was detected between the studied characters and different phylogroups except the significant resistance to cefotaxime, ceftazidime and aztreonam among phylogroups from CAUTI isolates. CONCLUSION Increased antibiotic resistance and ESBLs were detected in UPEC strains from CAUTI and Com-UTI. The strains from CAUTI significantly produced biofilm higher than Com-UTI strains. Phylogroup A was the predominate phylogroup and PAI IV536 was the most prevalent marker in all phylogroups from both types of UTI.

Abstract
AIMS Driven by increasing awareness of antibiotic stewardship, especially in the vulnerable group of patients with neurogenic lower urinary tract dysfunction (NLUTD), whose frequent need for invasive interventions leads to a high incidence of recurrent urinary tract infections (rUTIs), the goal was to find an alternative to antibiotic treatment. Our intention was for the treatment to be locally administered and well-tolerated as well as to avoid the risk of antimicrobial resistance. METHODS A retrospective analysis of 12 catheterized NLUTD patients was performed within the setting of an individual curative trial. The decision to implement the investigational intervention was made on an individual basis with the aim of eliminating lower urinary tract bacteria before diagnostic procedures or to treat rUTI. Electrochemically activated solution (ECAS) was used as bladder irrigation (BI). The following assessments were undertaken: microbiological analysis of urine, analysis of leukocytes/erythrocytes (per µl urine); microbial resistance and sensitivity to antibiotics before and after therapy; clinical signs and patients' state of health. RESULTS Eradication of bacteria or an increase in microbial sensitivity to antibiotics was observed in 50%-70% of patients. No adverse events were seen. Due to the restrictions of an individual curative trial, the results are limited by the small number of patients and the absence of a control group. CONCLUSION In NLUTD patients with rUTIs, the use of ECAS BI to eliminate bacteriuria before invasive procedures (e.g., urodynamics, preoperative procedures) or to treat rUTI was shown to be a promising alternative to antibiotic treatment.

Abstract
We conducted a quality improvement project at our large, public, tertiary-care, academic hospital to reduce the standardized infection ratio (SIR) of hospital-acquired catheter-associated urinary tract infections (CAUTIs). Our diagnostic stewardship program, based on education and audit and feedback, significantly reduced inpatient urine culture orders and CAUTI SIR.

Abstract
BACKGROUND Catheter-associated urinary tract infections (CAUTI) and central line-associated bloodstream infections (CLABSI) represent a substantial portion of health care-associated infections (HAIs) reported in the United States. The Targeted Assessment for Prevention Strategy is a quality improvement framework to reduce health care-associated infections. Data from the Targeted Assessment for Prevention Facility Assessments were used to determine common infection prevention gaps for CAUTI and CLABSI. METHODS Data from 2,044 CAUTI and 1,680 CLABSI assessments were included in the analysis. Items were defined as potential gaps if ≥33% respondents answered Unknown, ≥33% No, or ≥50% No or Unknown or Never, Rarely, Sometimes, or Unknown to questions pertaining to those areas. Review of response frequencies and stratification by respondent role were performed to highlight opportunities for improvement. RESULTS Across CAUTI and CLABSI assessments, lack of physician champions (<35% Yes) and nurse champions (<55% Yes), along with lack of awareness of competency assessments, audits, and feedback were reported. Lack of practices to facilitate timely removal of urinary catheters were identified for CAUTI and issues with select device insertion practices, such as maintaining aseptic technique, were perceived as areas for improvement for CLABSI. CONCLUSIONS These data suggest common gaps in critical components of infection prevention and control programs. The identification of these gaps has the potential to inform targeted CAUTI and CLABSI prevention efforts.

Abstract
Background: Catheter-associated urinary tract infection (CAUTI) is a frequent community-acquired infection and the most common nosocomial infection. Here, we developed a novel antimicrobial catheter concept that utilizes a silicone-based interpenetrating polymer network (IPN) as balloon material to facilitate a topical slow-release prophylaxis of antibacterial agents across the balloon to the urinary bladder. Methods: The balloon material was achieved by modifying low shore hardness silicone tubes with a hydrogel interpenetrating polymer in supercritical CO2 using the sequential method. Release properties and antibacterial efficacy of the IPN balloon treatment concept was investigated in vitro and in a porcine CAUTI model developed for the study. In the latter, Bactiguard Infection Protection (BIP) Foley catheters were also assessed to enable benchmark with the traditional antimicrobial coating principle. Results: Uropathogenic Escherichia coli was undetectable in urinary bladders and on retrieved catheters in the IPN treatment group as compared to control that revealed significant bacteriuria (>105 colony forming units/ml) as well as catheter-associated biofilm. The BIP catheters failed to prevent E. coli colonization of the bladder but significantly reduced catheter biofilm formation compared to the control. Conclusion: The IPN-catheter concept provides a novel, promising delivery route for local treatment in the urinary tract.

Abstract
BACKGROUND Until recently, there has been a lack of viable alternative to an indwelling urinary catheter for female patients that require precise urine output measurements. With the introduction of external female urinary catheters, we can now substitute this type of device for an indwelling urinary catheter in many patients, decreasing their risk of catheter-associated urinary tract infections. METHODS In this retrospective study, we analyzed the impact of a hospital-wide implementation of an external female urinary catheter at a large academic medical center. The study included female patients, greater than 18 years of age. We compared a 12-month period before and after device implementation to assess the impact on indwelling urinary catheter utilization and catheter-associated urinary tract infections rate. RESULTS Data included over 220,000 patient days, over 10,000 external urinary catheter days and 33,000 indwelling urinary catheter days. We found a statistically significant decrease in indwelling urinary catheter utilization following the implementation of the external female urinary catheter, but only in intensive care units. CONCLUSIONS It is our recommendation that facilities first implement the device in ICUs as this level of care was where we observed the most significant impact.

Abstract
BACKGROUND Microorganisms can migrate from the external environment to the patient's organism through the insertion of catheters. Despite being indispensable medical device, the catheter surface can be colonized by microorganisms and become a starting point for biofilm formation. Therefore, new technologies are being developed in order to modify surfaces to prevent the adhesion and survival of microorganisms. Patents with the use of DMPEI have been filed. OBJECTIVE In the present work, we coated latex catheter surfaces with 2 mg mL-1 DMPEI in different solvents, evaluated the wettability of the surface and the anti- biofilm activity of the coated catheter against Escherichia coli, Staphylococcus aureus, and Candida albicans. METHODS We coated the inner and outer catheter surfaces with 2 mg mL-1 of DMPEI solubilized in butanol, dimethylformamide, and cyclohexanone and the surfaces were analyzed visually. Contact angle measurement allowed the analysis of the wettability of the surfaces. The CFU mL-1 count evaluated E. coli, S. aureus, and C. albicans adhesion onto the control and treated surfaces. RESULTS The contact angle decreased from 50.48º to 46.93º on the inner surface and from 55.83º to 50.91º on the outer surface of latex catheters coated with DMPEI. The catheter coated with DMPEI showed anti-biofilm activity of 83%, 88%, and 93% on the inner surface and 100%, 92%, and 86% on the outer surface for E. coli, S. aureus, and C. albicans, respectively. CONCLUSION Latex catheter coated with DMPEI efficiently impaired the biofilm formation both on the outer and inner surfaces, showing a potential antimicrobial activity along with a high anti-biofilm activity for medical devices.

Abstract
AIM To evaluate the performance of a new catheter design based on different hydrodynamics aiming to reduce the development of biofilm, and compare it with a conventional Foley catheter (FC). METHODS The new proposed design (NPD) catheter is a modification of the FC, based on asymmetric positioning of the balloon and additional drainage holes allowing continuous urine drainage and complete voiding of the bladder. A first experiment was undertaken to assess drainage capability, and a second experiment was performed using a bioreactor with a set-up simulating the bladder and using the test catheter as a flow-through system. The biofilm formation of five bacterial species associated with catheter-associated urinary tract infection (CAUTI) was determined after 24 h of incubation using an MTT assay. Morphological evaluation was performed using scanning electron microscopy. In-vitro determination of residual fluid, and quantitative and morphological data on biofilm formation on the intravesical and intraluminal parts of the tested catheters were assessed. RESULTS Residual fluid was significantly higher in the FC (5.60 ± 0.43 mL) compared with the NPD catheter (0.2 ± 0.03 mL). The NPD catheter showed significantly less biofilm formation (P<0.0001) than the FC. Catheter design had a variable effect on biofilm formation depending on the bacterial strain tested. There was significantly less intraluminal biomass compared with intravesical biomass in both catheters (P<0.0001). Multi-layered biofilms that covered the FC surfaces completely were seen for all tested strains, while the NPD catheter surfaces showed reduced biofilm formation. CONCLUSIONS Modifications of the hydrodynamic characteristics of a catheter can significantly reduce bacterial colonization. Integrated design approaches combining chemical, mechanical and topographical elements can help to reduce the occurrence of CAUTI.

Abstract
Determining the need for bladder decompression and urinary diversion in the perioperative pediatric surgical patient can cause a clinical conundrum for the surgical team. Add in the several different types of urinary diversion devices possible, and the various materials associated therein and the process can suddenly seem unnecessarily daunting given the lack of concise recommendations and broad consensus. The decision to divert urine, though seemingly trivial, is associated with inherent risks. Managing and mitigating certain risks are best approached through proper education, selection, and technique. We provide a broad overview of pediatric catheter selection, indications, and pitfalls to streamline the process so that energy and attention can best be focused on the planned intervention at hand.
