At a glance: urinary catheterisation in males and females.

Urinary catheterisation is a crucial procedure in healthcare, requiring a thorough understanding of the anatomical and physiological differences between males and females to ensure safe and effective care. This guide explores the anatomy of the urinary system, detailing the kidneys, ureters, bladder, and urethra, and highlights key differences in catheterisation techniques for men and women. Emphasising evidence-based practices, it discusses recent advancements, such as antimicrobial catheters, and underscores the importance of comprehensive training and competency assessments for healthcare providers. Additionally, the guide advocates for patient-centred approaches, multidisciplinary collaboration, and adherence to updated policies to reduce complications such as catheter-associated urinary tract infections (CAUTIs). By integrating these critical evaluations and best practices, health professionals can enhance patient outcomes and maintain high standards of care in urinary catheterisation.

Adherence to Evidence-Based Guidelines and Implications When Designing Electronic Documentation for Urinary Catheters.

AIM: The aim of this study was to investigate the point prevalence and the rate of adherence to evidence-based guidelines for patients who had indwelling urinary catheters in three Australian acute care hospitals. DESIGN: A cross-sectional observational design was used. METHODS: A multisite cross-sectional observational design was utilised in three acute hospitals across Australia. Data were collected from each site in a single day directly from observation of the patient, the bedside notes and medical records. The data collected included observations of clinical care and scrutiny of the documentation of the insertion details and catheter care using best practice guidelines. RESULTS: Of the 1730 patients audited, 47% were female. The mean point prevalence of catheters in situ across three sites was 12.9%. Correct documentation compliance was reported to be, on average, 40%. Documentation was significantly better when a template was available to guide information recorded: this was regardless of whether it was hard copy or electronic. Overall, clinical care compliance with best practices was 77%. Of note for improvement was the fixing of the urinary catheter to the thigh in highly dependent patients. CONCLUSION: It was identified that there is a need for improvement across all three sites: specifically regarding securement of the urinary catheter to the patient's thigh within the ICU. In addition, it was identified that there is a need for documentation of the urine bag change in ward areas. Documentation may be improved by incorporating templates into healthcare documentation systems in the future. Further work is needed to ensure nurses are aware of the adverse effects of urinary catheters and thus, the need to adhere to best practice guidelines. PATIENT OR PUBLIC CONTRIBUTION: There has been no patient or public contribution. REPORTING METHOD: We have adhered to the STROBE guidelines for reporting.

Knowledge, Attitude, Practice, and Associated Factors Toward the Prevention of Catheter-Associated Urinary Tract Infection Among Nurses in Ethiopia: Cross-Sectional Study.

Introduction: Catheter-associated urinary tract infection (CAUTI) is one of the major device-associated hospital-acquired infections of the urinary tract. The nurse's knowledge, attitude, and practice (KAP) are the primary inputs for preventing the patient from developing CAUTI. Nevertheless, poor knowledge, a negative attitude, and poor practice toward the prevention of CAUTI among nurses remain an extensive problem. Objective: This study aimed to assess KAP and associated factors toward the prevention of CAUTI among nurses in public hospitals in Addis Ababa, Ethiopia, in 2021. Methods: An institution-based cross-sectional study was conducted among nurses from March 1 to April 30, 2021, in five public hospitals in Addis Ababa, Ethiopia. A total of 344 nurses were chosen for the study using a systematic random sampling technique. Data were collected using knowledge, attitude, and practice toward the prevention of CAUTI questionnaires. Data were entered into Epi Data 4.2 and exported into SPSS 25 for analysis. Binary and multivariate logistic regression were performed, and the statistical significance of associations between the variables was determined using odds ratios with a 95% confidence interval and p < .05. Results: The study included 344 nurses, with a 97.7% response rate. Of the total nurses, 42.7% had good knowledge, 48.0% had a positive attitude, and 54.9% had good practice toward the prevention of CAUTI. Being married, having guidelines, and having a positive attitude were associated with good knowledge, whereas being married, having good knowledge, and having good practice were associated with a positive attitude toward the prevention of CAUTI. Having a high monthly income, having guidelines, having good knowledge, and having a positive attitude were associated with good practices toward the prevention of CAUTI. Conclusion: The findings of this study show that nurses have a low level of knowledge, a negative attitude, and poor practice toward the prevention of CAUTI. Factors such as marital status, monthly income, and having guidelines in the working unit were associated with KAP toward the prevention of CAUTI. Therefore, the Ministry of Health and Hospital Interventions focused on these findings are required to improve KAP toward the prevention of CAUTI among nurses.

Determinants of Healthcare-Associated Infections in King Abdulaziz Specialized Hospital in Taif, Saudi Arabia.

BACKGROUND: Healthcare-associated infections (HAIs) represent a significant challenge in hospital settings, contributing to increased morbidity, mortality, and healthcare costs. This study aimed to estimate the prevalence and socio-demographic and clinical determinants of HAIs at the King Abdulaziz Specialized Hospital (KAASH) in Taif, Saudi Arabia. METHODOLOGY: A hospital-based cross-sectional study was conducted from March 2023 to January 2024 targeting inpatients aged 18 and above in all units and wards. Data were collected using the National Healthcare Safety Network (NHSN) criteria for definitions of surveillance. A structured questionnaire gathered socio-demographic and clinical data from patients or next of kin if the patient was not fully oriented. Descriptive statistics were performed, and analytical methods used included Pearson chi-square test, Pearson correlation, independent t-test, and one-way analysis of variance. RESULTS: Among 318 participants included in this study, the mean age of participants was 56.44 years, with a slight female predominance (n=164, 51.6%). Hypertension (n=162, 50.9%) and diabetes (n=126, 39.6%) were the most prevalent comorbidities. Pneumonia (n=60, 26.8%) and trauma (n=55, 17.4%) were the leading causes of admission. The two most common HAIs included catheter-associated urinary tract infections (CAUTI) (n=124, 39%) and central line-associated bloodstream infections (CLABSI) (n=74, 23.3%). The primary causative organisms were Klebsiella pneumoniae (n=96, 30.2%) and Acinetobacter baumannii (n=32, 10.1%). The most significant predictors of HAIs were as follows: For CLABSI, risk factors include having three or more comorbidities, fever above 37.8°C, chills or rigors, hypotension, and positive blood culture. For CAUTI, key predictors were urinary tract infection (UTI), positive urine culture, acute pain or swelling of the testes, suprapubic tenderness, visible hematuria, and leukocytosis. Significant predictors of bloodstream infections (BSI) include having a BSI, positive blood culture, chills or rigors, and hypotension. Fever and hypotension increased CLABSI and BSI risk but reduced the CAUTI risk. CONCLUSION: The study highlights a significant burden of HAIs at the KAASH, with multiple predictors. The findings underscore the need for robust infection control measures and targeted interventions to reduce HAI incidence and improve patient outcomes.

Medicated Foley Catheters Do Not Prevent Catheter-Associated Urinary Tract Infection: A Systematic Review of Randomized Controlled Trials.

Infections of the urinary tract are among some of the most common infections treated in clinical practice. Numerous risk factors play an intrinsic role in the development of such infections, namely: age, sexual intercourse, prolonged use of feminine hygiene products, instrumentation, pregnancy, sexually transmitted infections, obstructive uropathy such as prostatic enlargement or urethral strictures, compromised immunity, and constipation. A major cause of urinary tract infections (UTIs) in hospitalized patients is catheter-associated urinary tract infections (CAUTIs). This systematic review aims to identify the causative agents and risk factors and to determine whether nitrofurazone, silver alloy, or zinc oxide-impregnated or coated/medicated Foley catheters, or non-medicated (standard) Foley catheters, can reduce the incidence of CAUTIs. A systematic review was conducted on the following databases: PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Trip medical database, and Google Scholar. A combination of keywords and Boolean operators was used ((((urinary tract infections) OR (urinary catheterization)) OR (prevention AND control)) ) AND (catheter-associated infections) for data extraction. All the randomized controlled clinical trials (RCTs) completed and available between January 1, 2005, and June 30, 2024, which focused on the prevention of CAUTIs, were screened thoroughly and were included in this systematic review. The Cochrane risk-of-bias tool for randomized trials (RoB 2) tool was used for risk of bias assessment. The Robvis visualization tool (McGuinness, LA, Higgins, JPT. Risk-of-bias VISualization (robvis): An R package and Shiny web app for visualizing risk-of-bias assessments. Res Syn Meth. 2020; 1-7) was used for development of traffic light plots and weighted bar plots for risk of bias. The literature search conducted produced 41,909 articles. Among these 19,076 were noted as duplicates and were excluded in the initial analysis; 22,833 manuscripts were thus screened after deduplication. Abstracts, case studies, reports, editorials, viewpoints, cross-sectional studies, cohort studies, case-control studies, case series, and letters to the editor/correspondence manuscripts (n = 22,745) were additionally excluded. A total of 88 full-text articles were assessed for eligibility. An in-depth evaluation and analysis further excluded 82 articles from the analysis quality assessment based on inclusion and exclusion criteria. Six RCTs were finally assessed regarding the prevention of CAUTIs and were ultimately included in the systematic review. The primary causative agents involved in the CAUTIs were found to be mainly Gram-negative bacteria such as Escherichia coli, Pseudomonas aeruginosa, and Enterococcus faecalis. The risk factors noted for the development of these CAUTIs ranged from urethral trauma, overdistention of the bladder, prolonged catheterization, to improper handling of the urine bag. No significant advantage was noted between the use of medicated and non-medicated standard Foley catheters. The aseptic technique and indications followed for the catheterization play a vital role in the prevention of CAUTIs, and more cognizance thereof will aid in the reduction of the development of CAUTIs.

Validity of urinary catheter specimens for diagnosis of urinary tract infection in patients with short-term catheterization.

Current guidelines recommend urine culture after catheter replacement to diagnose catheter-associated urinary tract infections (CA-UTI) in patients with long-term catheters, but it's unclear if this applies to short-term catheterizations. We studied 52 patients with catheters for less than 28 days, showing symptoms of CA-UTI. We collected urine from the catheter port initially and from the new catheter within 2 hours of replacement. Positive culture rates were 36.5 % before and 28.8 % after replacement. Significant differences in urine culture results were observed in 32.7 % of cases postreplacement (P = .0184), increasing to 78.9 % after excluding negative pre-replacement cultures (P = 0.0003). Duration of catheterization didn't affect urine bacteriology changes post-replacement. This suggests that urine bacteriology often differs after catheter replacement in short-term catheterizations.

Novel Nano Drug-Loaded Hydrogel Coatings for the Prevention and Treatment of CAUTI.

Catheter-associated urinary tract infection (CAUTI) is a prevalent type of hospital-acquired infection, affecting approximately 15% to 25% of patients with urinary catheters. Long-term use of the catheter can lead to colonization of microorganisms and biofilm formation, and may develop into bacterial CAUTI. However, the frequent replacement of catheters in clinical settings can result in tissue damage, inflammation, ulceration, and additional complications, causing discomfort and pain for patients. In light of these challenges, a novel nanodrug-supported hydrogel coating called NP-AM/FK@OMV-P/H has been developed in this study. Through in vitro experiments, it is confirmed that OMV nano-loaded liquid gel coating has an effective reaction against E.coli HAase and releases antibacterial drugs. This coating has also demonstrated strong inhibition of E.coli and has shown the ability to inhibit the formation of bacterial biofilm. These findings highlight the potential of the OMV nanoparticle gel coating in preventing and treating bacterial infections. Notably, NP-AM/FK@OMV-P/H has exhibited greater efficacy against multidrug-resistant E.coli associated with UTIs compared to coatings containing single antimicrobial peptides or antibiotics. Additionally, it has demonstrated good biosecurity. In conclusion, the NP-AM/FK@OMV-P/H coating holds great potential in providing benefits to patients with CAUTI.

Materials-based incidence of urinary catheter associated urinary tract infections and the causative micro-organisms: systematic review and meta-analysis.

BACKGROUND: Both long (> 30 days) and short-term (≤ 30 days) catheterisation has been associated with urinary tract infections (UTIs) due to the invasive nature of device insertion through the urethra. Catheter associated Urinary Tract Infections (CAUTIs) are common (prevalence of ~ 8.5%) infections which can be treated with antibiotics; however, CAUTIs are both expensive to treat and contributes to the antibiotic usage crisis. As catheters are unlikely be replaced for the management of patients' urination, ways of reducing CAUTIs are sought out, using the catheter device itself. The aim of this review is to assess the incidence of CAUTI and the causative micro-organisms when different urinary catheter devices have been used by humans, as reported in published research articles. METHODS: A Systematic Literature Review was conducted in Ovid Medline, Web of Science and PubMed, to identify studies which investigated the incidence of UTI and the causative micro-organisms, in patients with different urinary catheter devices. The articles were selected based on a strict set of inclusion and exclusion criteria. The data regarding UTI incidence was extracted and calculated odds ratio were compared across studies and pooled when types of catheters were compared. CAUTI causative micro-organisms, if stated within the research pieces, were also gathered. RESULTS: A total of 890 articles were identified, but only 26 unique articles met the inclusion/exclusion criteria for this review. Amongst the large cohort there were catheters of materials silicone, latex and PVC and catheter modifications of silver nanoparticles and nitrofurantoin antibiotics. The meta-analysis did not provide a clear choice towards a single catheter against another although silver-based catheters, and silver alloy, appeared to statistically reduce the OR of developing CAUTIs. At genus level the three commonest bacteria identified across the cohort were E. coli, Enterococcus spp. and Pseudomonas spp. whilst considering only at the genus level, with E. coli, Klebsiella pneumonia and Enterococcus faecalis most common at the species-specific level. CONCLUSIONS: There does not appear to be a catheter type, which can significantly reduce the incidence of CAUTI's in patients requiring catheterisation. Ultimately, this warrants further research to identify and develop a catheter device material that will reduce the incidence for CAUTIs.

Trash into Treasure: Nano-coating of Catheter Utilizes Urine to Deprive H2S Against Persister and Rip Biofilm Matrix.

Bacteria-derived hydrogen sulfide (H2S) often contributes to the emergence of antibiotic-recalcitrant bacteria, especially persister (a sub-population of dormant bacteria), thus causing the treatment failure of Catheter-associated urinary tract infection (CAUTI). Here, an H2S harvester nanosystem to prevent the generation of persister bacteria and disrupt the dense biofilm matrix by the self-adaptive ability of shape-morphing is prepared. The nanosystem possesses a core-shell structure that is composed of liquid metal nanoparticle (LM NP), AgNPs, and immobilized urease. The nanosystem decomposes urea contained in urine to generate ammonia for eliminating bacteria-derived H2S. Depending on the oxidative layer of liquid metal, the nanosystem also constitutes a long-lasting reservoir for temporarily storing bacteria-derived H2S, when urease transiently overloads or in the absence of urine in a catheter. Depriving H2S can prevent the emergence of persistent bacteria, enhancing the bacteria-killing efficiency of Ga3+ and Ag+ ions. Even when the biofilm has formed, the urine flow provides heat to trigger shape morphing of the LM NP, tearing the biofilm matrix. Collectively, this strategy can turn trash (urea) into treasure (H2S scavengers and biofilm rippers), and provides a new direction for the antibacterial materials application in the medical field.

Bundle care approach to reduce device associated infections in post-living-donor-liver transplantation in a tertiary care hospital, Egypt.

BACKGROUND: Device-associated infections (DAIs) are a significant cause of morbidity following living donor liver transplantation (LDLT). We aimed to assess the impact of bundled care on reducing rates of device-associated infections. METHODS: We performed a before-and-after comparative study at a liver transplantation facility over a three-year period, spanning from January 2016 to December 2018. The study included a total of 57 patients who underwent LDLT. We investigated the implementation of a care bundle, which consists of multiple evidence-based procedures that are consistently performed as a unified unit. We divided our study into three phases and implemented a bundled care approach in the second phase. Rates of pneumonia related to ventilators [VAP], bloodstream infections associated with central line [CLABSI], and urinary tract infections associated with catheters [CAUTI] were assessed throughout the study period. Bacterial identification and antibiotic susceptibility testing were performed using the automated Vitek-2 system. The comparison between different phases was assessed using the chi-square test or the Fisher exact test for qualitative values and the Kruskal-Wallis H test for quantitative values with non-normal distribution. RESULTS: In the baseline phase, the VAP rates were 73.5, the CAUTI rates were 47.2, and the CLABSI rates were 7.4 per one thousand device days (PDD). During the bundle care phase, the rates decreased to 33.3, 18.18, and 4.78. In the follow-up phase, the rates further decreased to 35.7%, 16.8%, and 2.7% PDD. The prevalence of Klebsiella pneumonia (37.5%) and Methicillin resistance Staph aureus (37.5%) in VAP were noted. The primary causative agent of CAUTI was Candida albicans, accounting for 33.3% of cases, whereas Coagulase-negative Staph was the predominant organism responsible for CLABSI, with a prevalence of 40%. CONCLUSION: This study demonstrates the effectiveness of utilizing the care bundle approach to reduce DAI in LDLT, especially in low socioeconomic countries with limited resources. By implementing a comprehensive set of evidence-based interventions, healthcare systems can effectively reduce the burden of DAI, enhance infection prevention strategies and improve patient outcomes in resource-constrained settings.

Six-year evaluation of device-associated nosocomial infections in intensive care units.

INTRODUCTION: Invasive device-associated nosocomial infections commonly occur in intensive care units (ICUs). These infections include intravascular catheter-related bloodstream infection (CRBSI), ventilator-associated pneumonia (VAP), and catheter-associated urinary tract infection (CAUTI). This study aimed to evaluate the factors associated with invasive device-associated nosocomial infections based on the underlying diseases of the patients and antibiotic resistance profiles of the pathogens causing the infections detected in the ICU in our hospital over a five-year period. METHODOLOGY: Invasive device-associated infections (CRBSI, VAP, and CAUTI) were detected retrospectively by the laboratory- and clinic-based active surveillance system according to the criteria of the US Centers for Disease Control and Prevention (CDC) in patients hospitalized in the ICU of the tertiary hospital between 1 January 2018 and 30 June 2023. RESULTS: A total of 425 invasive device-associated nosocomial infections and 441 culture results were detected (179 CRBSI, 176 VAP, 70 CAUTI). Out of them, 57 (13.4%) patients had hematological malignancy, 145 (34.1%) had solid organ malignancy, and 223 (52.5%) had no histopathologic diagnosis of any malignancy. An increase in extended-spectrum beta lactamase (ESBL) and carbapenem resistance in pathogens was detected during the study period. CONCLUSIONS: Antibiotic resistance of the Gram-negative bacteria associated with invasive device-associated infections increased during the study period. Antimicrobial stewardship will reduce rates of nosocomial infections, reduce mortality, and shorten hospital stay. Long-term catheterization and unnecessary antibiotic use should be avoided.

Draft genome sequences of an Enterobacter hormaechei and Providencia rettgeri isolated from the urine of a male experiencing a catheter-associated urinary tract infection.

Catheter-associated urinary tract infections (CAUTIs) can be caused by a variety of microbes. Here, we describe the draft genome assemblies of two species-Enterobacter hormaechei and Providencia rettgeri-purified from the catheterized urine sample of a male diagnosed with a CAUTI.

Urinary catheter alleviation navigator protocol (UCANP): Update to the hospital-wide implementation at a single tertiary health care center.

BACKGROUND: Catheter-associated urinary tract infections are commonly reported health care-associated infections. It was demonstrated that the urinary catheter alleviation navigator protocol (UCANP) pilot resulted in a reduction of catheter utilization and catheter days. METHODS: Quality improvement initiative that was implemented at a single urban, tertiary health care center, focusing on early discontinuation of indwelling urinary catheters (IUCs) and avoidance of reinsertion. The protocol was expanded hospital-wide from September 2020 to April 2022. We compared IUC utilization, IUC standardized utilization ratio (SUR), and catheter-associated urinary tract infection standardized infection ratio in the preintervention period (March 2020 to August 2020) to the postintervention period (May 2022 to October 2022). RESULTS: Preimplementation, 2 patients with IUC removal were placed on UCANP. Postimplementation, 835 (45%) patients with IUC removal participated in the protocol. The number of patients requiring IUC reinsertion did not differ among the 2 groups. IUC utilization was significantly decreased from 0.28 to 0.24 with a 14% reduction (P = .025). SUR decreased by 11% from 0.778 to 0.693 (P = .007) and standardized infection ratio by 84% from 0.311 to 0.049 (P = .009). CONCLUSIONS: Our protocol significantly reduced IUC utilization and SUR after hospital-wide implementation. UCANP is a safe and effective strategy that can potentially decrease unnecessary IUCs in patients with transient urinary retention.

High efficacy treatment of murine Pseudomonas aeruginosa catheter-associated urinary tract infections using the c-di-GMP modulating anti-biofilm compound Disperazol in combination with ciprofloxacin.

Persistent urinary tract infections (UTIs) in hospitalized patients constitute an important medical problem. It is estimated that 75% of nosocomial UTIs are associated with urinary tract catheters with P. aeruginosa being a species that forms biofilms on these catheters. These infections are highly resistant to standard-of-care antibiotics, and the effects of the host immune defenses, which allows for development of persistent infections. With antibiotics losing their efficacy, new treatment options against resilient infections, such as catheter-associated urinary tract infections (CAUTIs), are critically needed. Central to our anti-biofilm approach is the manipulation of the c-di-GMP signaling pathway in P. aeruginosa to switch bacteria from the protective biofilm to the unprotected planktonic mode of life. We recently identified a compound (H6-335-P1), that stimulates the c-di-GMP degrading activity of the P. aeruginosa BifA protein which plummets the intracellular c-di-GMP content and induces dispersal of P. aeruginosa biofilm bacteria into the planktonic state. In the present study, we formulated H6-335-P1 as a hydrochloride salt (Disperazol), which is water-soluble and facilitates delivery via injection or oral administration. Disperazol can work as a monotherapy, but we observed a 100-fold improvement in efficacy when treating murine P. aeruginosa CAUTIs with a Disperazol/ciprofloxacin combination. Biologically active Disperazol reached the bladder 30 min after oral administration. Our study provides proof of concept that Disperazol can be used in combination with a relevant antibiotic for effective treatment of CAUTIs.

Reducing catheter-associated urinary tract infection in high dependency unit: an eighteen-month quality improvement intervention study period.

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.

Implementation of a multi-modal intervention adopting new technologies, clinical services, and feedback improves catheter-associated urinary tract infections.

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.

A study protocol of a comparative mixed study of the T-Control catheter.

Background: Foley catheters have been subject to limited development in the last few decades. They fulfil their basic function of draining urine from the bladder but cause other associated problems. T-Control is a new silicone Foley catheter with an integrated fluid control valve whose design aims to reduce the risks associated with bladder catheterization by a multifactorial approach. The general purpose of this study is to determine the effectiveness, comfort, and experience of the patient catheterized with T-Control® compared with patients with a conventional Foley catheter. Study Design: This trial is a mixed-method study comprising a two-arm, pilot comparative study with random allocation to T-Control catheter or traditional Foley catheter in patients with long-term catheterization and a study with qualitative methodology, through discussion groups. Endpoints: The comfort and acceptability of the T-Control® device (qualitative) and the quality of life related to self-perceived health (quantitative) will be analysed as primary endpoints. As secondary endpoints, the following will be analysed: magnitude and rate of infections (symptomatic and asymptomatic); days free of infection; indication of associated antibiotic treatments; determination of biofilm; number of catheter-related adverse events; use of each type of catheterization's healthcare resources; and level of satisfaction and workload of health professionals. Patients and Methods: Eligible patients are male and female adults aged ≥18 years, who require a change of long-term bladder catheter. The estimated sample size is 50 patients. Patient follow-up includes both the time of catheter insertion and its removal or change 4 weeks later, plus the time until the discussion groups take place.

Catheter-associated urinary tract infection (CAUTI) reduction in a neuroscience intensive care unit: A multidisciplinary approach.

Utilizing a multidisciplinary approach to identify catheter-associated urinary tract infection (CAUTI) risks in Neuroscience intensive care patients admitted for aneurysmal subarachnoid hemorrhage, our CAUTI rate decreased from 5.903 per 1,000 catheter days (June 2020-June 2021) to 0.371 per 1,000 catheter days in our postintervention time period (July 2021-March 2023). A review of our clinical treatment guideline to optimize the timing of indwelling urinary catheters and medication management related to bowel regimens has resulted in a sustained CAUTI reduction, particularly in postaneurysmal subarachnoid hemorrhage patients in the Neuroscience intensive care unit.

Tackling catheter-associated urinary tract infections with next-generation antimicrobial technologies.

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.
