Impact of healthcare-associated infections within 7-days of acute stroke on health outcomes and risk of care-dependency: a multi-centre registry-based cohort study. Intern Emerg Med 2024; 19:919-929. [PMID: 38517643 PMCID: PMC11186937 DOI: 10.1007/s11739-024-03543-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2023] [Accepted: 01/16/2024] [Indexed: 03/24/2024]
Abstract
Healthcare-associated infections (HCAIs) in patients admitted with acute conditions remain a major challenge to healthcare services. Here, we assessed the impact of HCAIs acquired within 7-days of acute stroke on indicators of care-quality outcomes and dependency. Data were prospectively collected (2014-2016) from the Sentinel Stroke National Audit Programme for 3309 patients (mean age = 76.2 yr, SD = 13.5) admitted to four UK hyperacute stroke units (HASU). Associations between variables were assessed by multivariable logistic regression (odds ratios, 95% confidence intervals), adjusted for age, sex, co-morbidities, pre-stroke disability, swallow screening, stroke type and severity. Within 7-days of admission, urinary tract infection (UTI) and pneumonia occurred in 7.6% and 11.3% of patients. Female (UTI only), older age, underlying hypertension, atrial fibrillation, previous stroke, pre-stroke disability, intracranial haemorrhage, severe stroke, and delay in swallow screening (pneumonia only) were independent risk factors of UTI and pneumonia. Compared to patients without UTI or pneumonia, those with either or both of these HCAIs were more likely to have prolonged stay (> 14-days) on HASU: 5.1 (3.8-6.8); high risk of malnutrition: 3.6 (2.9-4.5); palliative care: 4.5 (3.4-6.1); in-hospital mortality: 4.8 (3.8-6.2); disability at discharge: 7.5 (5.9-9.7); activity of daily living support: 1.6 (1.2-2.2); and discharge to care-home: 2.3 (1.6-3.3). In conclusion, HCAIs acquired within 7-days of an acute stroke led to prolonged hospitalisation, adverse health consequences and risk of care-dependency. These findings provide valuable information for timely intervention to reduce HCAIs, and minimising subsequent adverse outcomes.

Abstract
Background Quality of life and care varies between and within the care homes in which almost half a million older people live and over half a million direct care staff (registered nurses and care assistants) work. The reasons are complex, understudied and sometimes oversimplified, but staff and their work are a significant influence. Objective(s) To explore variations in the care home nursing and support workforce; how resident and relatives' needs in care homes are linked to care home staffing; how different staffing models impact on care quality, outcomes and costs; how workforce numbers, skill mix and stability meet residents' needs; the contributions of the care home workforce to enhancing quality of care; staff relationships as a platform for implementation by providers. Design Mixed-method (QUAL-QUANT) parallel design with five work packages. WP1 - two evidence syntheses (one realist); WP2 - cross-sectional survey of routine staffing and rated quality from care home regulator; WP3 - analysis of longitudinal data from a corporate provider of staffing characteristics and quality indicators, including safety; WP4 - secondary analysis of care home regulator reports; WP5 - social network analysis of networks likely to influence quality innovation. We expressed our synthesised findings as a logic model. Setting English care homes, with and without nursing, with various ownership structures, size and location, with varying quality ratings. Participants Managers, residents, families and care home staff. Findings Staffing's contribution to quality and personalised care requires: managerial and staff stability and consistency; sufficient staff to develop 'familial' relationships between staff and residents, and staff-staff reciprocity, 'knowing' residents, and skills and competence training beyond induction; supported, well-led staff seeing modelled behaviours from supervisors; autonomy to act. Outcome measures that capture the relationship between staffing and quality include: the extent to which resident needs and preferences are met and culturally appropriate; resident and family satisfaction; extent of residents living with purpose; safe care (including clinical outcomes); staff well-being and job satisfaction were important, but underacknowledged. Limitations Many of our findings stem from self-reported and routine data with known biases - such as under reporting of adverse incidents; our analysis may reflect these biases. COVID-19 required adapting our original protocol to make it feasible. Consequently, the effects of the pandemic are reflected in our research methods and findings. Our findings are based on data from a single care home operator and so may not be generalised to the wider population of care homes. Conclusions Innovative and multiple methods and theory can successfully highlight the nuanced relationship between staffing and quality in care homes. Modifiable characteristics such as visible philosophies of care and high-quality training, reinforced by behavioural and relational role modelling by leaders can make the difference when sufficient amounts of consistent staff are employed. Greater staffing capacity alone is unlikely to enhance quality in a cost-effective manner. Social network analysis can help identify the right people to aid adoption and spread of quality and innovation. Future research should focus on richer, iterative, evaluative testing and development of our logic model using theoretically and empirically defensible - rather than available - inputs and outcomes.

Cost-effectiveness of a novel urethral catheter safety device in preventing catheterization injuries in the UK. J Med Econ 2024; 27:154-164. [PMID: 38126355 DOI: 10.1080/13696998.2023.2298121] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Accepted: 12/19/2023] [Indexed: 12/23/2023]
Abstract
AIMS Intraurethral catheter balloon inflation is a substantial contributor to significant catheter-related urethral injury. A novel safety valve has been designed to prevent these balloon-inflation injuries. The purpose of this evaluation was to assess the cost-effectiveness of urethral catheterisation with the safety valve added to a Foley catheter versus the current standard of care (Foley catheter alone). MATERIALS AND METHODS The analysis was conducted from the UK public payer perspective on a hypothetical cohort of adults requiring transurethral catheterization. A decision tree was used to capture outcomes in the first 30 days following transurethral catheterization, followed by a Markov model to estimate outcomes over a person's remaining lifetime. Clinical outcomes included catheter balloon injuries [CBIs], associated short-term complications, urethral stricture disease, life years and QALYs. Health-economic outcomes included total costs, incremental cost-effectiveness ratio, net monetary benefit (NMB) and net health benefit. RESULTS Over a person's lifetime, the safety valve was predicted to reduce CBIs by 0.04 per person and CBI-related short-term complications by 0.03 per person, and nearly halve total costs. The safety valve was dominant, resulting in 0.02 QALYs gained and relative cost savings of £93.19 per person. Probabilistic sensitivity analysis indicated that the safety valve would be cost-saving in 97% of simulations run versus standard of care. CONCLUSIONS The addition of a novel safety valve aiming to prevent CBIs during transurethral catheterization to current standard of care was estimated to bring both clinical benefits and cost savings.

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

Abstract
Urinary tract infections are among the most prevalent types of healthcare-associated infections (HAIs) in hospitals and nursing homes, and they are primarily a result of unnecessary catheter usage and inadequate care. In Portugal, epidemiological data indicate that catheter-associated urinary tract infections (CAUTIs) remain widespread in clinical settings, resulting in increased morbidity and mortality rates among vulnerable populations. This study aimed to assess urinary catheter use in an oncology ward in Portugal and to evaluate nurses' adherence to the government-endorsed standards for preventing CAUTIs. An observational study was conducted over a four-month period with daily assessments of nurses' practices during urinary catheter insertion and maintenance using a government-endorsed auditing tool. Data were collected through on-site observations and nurses' feedback. The findings revealed a urinary catheter utilization rate of 17.99%. However, there was a lack of complete adherence to government-endorsed standards among oncology nurses (0%). These results indicate that current practices lack evidence-based standardization. Therefore, there is a need to develop and implement quality improvement initiatives to enhance patient safety and experiences.

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
OBJECTIVE To estimate the cost-effectiveness of single-use hydrophilic-coated intermittent catheters (HCICs) versus single-use uncoated intermittent catheters (UICs) for urinary catheterization. METHODS The evaluation took a UK national health service (NHS) perspective. The population of interest were people using intermittent catheters, with either a spinal cord injury or multiple sclerosis. A Markov model was developed that estimated costs and clinical evidence over the lifetime of a hypothetical cohort and applied health-related quality-of-life estimates. Model inputs were sourced from published evidence, including a network meta-analysis to inform the treatment effect (reduction in catheter-associated urinary tract infections [CAUTIs]), and were supported by expert opinion. The model outputs included per-patient lifetime costs, quality-adjusted life years (QALYs), and the incremental cost effectiveness ratio (ICER). Event counts were also produced. RESULTS Using HCICs instead of UICs could prevent seven CAUTI events per patient over a lifetime horizon (1.8 requiring secondary care). Overall, lifetime use of HCICs is £3,183 more expensive than use of UICs per patient. However, for these additional costs, 0.55 QALYs are gained. The ICER is £5,755 per additional QALY gained. Key drivers of the model results were identified and subject to sensitivity analyses. The results were found to be robust to parameter uncertainty. CONCLUSION HCICs are likely to be a cost-effective alternative to UICs, a result driven by substantial reductions in the number of CAUTIs. Their adoption across clinical practice could avoid a substantial number of infections, freeing up resources in the NHS and reducing antibiotic use in urinary catheter users.

Abstract
Catheter-associated urinary tract infection (CAUTI) is a leading cause of hospital-acquired infections worldwide causing debilitating illness for patients as well as a significant financial and treatment burden on health services. CAUTI is linked with the build-up of biofilms on catheter surfaces which act as a reservoir for infection. Additionally, urease-producing bacteria such as Gram-negative Proteus mirabilis (PM), can form crystalline biofilms which encrust catheter surfaces ultimately leading to blockages which require immediate removal of the catheter. Currently there are limited treatments available to prevent the formation of biofilms by PM as well as other urinary tract infection causing bacteria. A novel concept for a light-guiding urinary catheter is presented where a silicone elastomer waveguide incorporated along the length of the catheter is used to irradiate the catheter surfaces with antimicrobial blue light (405 nm) to prevent biofilm formation in situ. The prototype device is mass producible while also easy to fabricate in a lab setting for research studies. The inhibitory effect of blue light on PM biofilm formation over a range of irradiances is described for the first time showing an LD90 at 192–345 J/cm2 and total inhibition at 1,700 J/cm2In vitro studies show that the light-guiding catheter (LGC) prototypes exhibit a 98% inhibition in PM biofilm formation inside the catheter lumen at an average estimated irradiance of 30–50 mW/cm2 (324–540 J/cm2 fluence) showing that the concept is highly effective, promising to be a powerful and economical antimicrobial approach to prevent catheter associated biofilm development and blockage.

Abstract
Healthcare-associated infection (HAI) is a major cause of morbidity, mortality and cost, which vary widely by region and hospital. In this case-control study, we calculated losses attributable to HAI in central China. A total of 2976 patients in 10 hospitals were enrolled, and the incidence rate of HAI (range, 0.88–4.15%) was significantly, but negatively associated with the cost per 1000 beds of its prevention (range, $24 929.76–$53 146.41; r = −0.76). The per capita economic loss attributable to HAIs was $2047.07 (interquartile range, $327.63–$6429.17), mainly from the pharmaceutical cost (median, $1044.39). The HAIs, which occurred in patients with commercial medical insurance, affected the haematologic system and caused by Acinetobacter baumannii, contributed most to the losses (median, $3881.55, $4734.20 and $9882.75, respectively). Furthermore, the economic losses attributable to device-associated infections and hospital-acquired multi-drug resistant bacteria were two to four times those of the controls. The burden attributable to HAI is heavy, and opportunities for easing this burden exist in several areas, including that strengthening antibiotic stewardship and practicing effective bundle of HAI prevention for patients carrying high-risk factors, for example, elders or those with catheterisations in healthcare institutions, and accelerating the medical insurance payment system reform based on diagnosis-related groups by policy-making departments.

Abstract
BACKGROUND Various washout policies are widely used in adults living with long-term catheters (LTC). There is currently insufficient evidence on the benefits and potential harms of prophylactic LTC washout policies in the prevention of blockages and other LTC-related adverse events, such as urinary tract infections. CATHETER II tests the hypothesis that weekly prophylactic LTC washouts (normal saline or citric acid) in addition to standard LTC care reduce the incidence of catheter blockage requiring intervention compared to standard LTC care only in adults living with LTC. METHODS CATHETER II is a pragmatic three-arm open multi-centre superiority randomised controlled trial with an internal pilot, economic analysis, and embedded qualitative study. Eligible participants are adults aged ≥ 18 years, who have had a LTC in use for ≥ 28 days, have no plans to discontinue the use of the catheter, are able to undertake the catheter washouts, and complete trial documentation or have a carer able to help them. Participants are identified from general practitioner practices, secondary/tertiary care, community healthcare, care homes, and via public advertising strategies. Participants are randomised 1:1:1 to receive a weekly saline (0.9%) washout in addition to standard LTC care, a weekly citric acid (3.23%) washout in addition to standard LTC care or standard LTC care only. Participants and/or carers will receive training to administer the washouts. Patient-reported outcomes are collected at baseline and for 24 months post-randomisation. The primary clinical outcome is catheter blockage requiring intervention up to 24 months post-randomisation expressed per 1000 catheter days. Secondary outcomes include symptomatic catheter-associated urinary tract infection requiring antibiotics, catheter change, adverse events, NHS/ healthcare use, and impact on quality of life. DISCUSSION This study will guide treatment decision-making and clinical practice guidelines regarding the effectiveness of various prophylactic catheter washout policies in men and women living with LTC. This research has received ethical approval from Wales Research Ethics Committee 6 (19/WA/0015). TRIAL REGISTRATION ISRCTN ISRCTN17116445 . Registered prospectively on 06 November 2019.

J Clin Nurs 2022; 32:2155-2177. [PMID: 35676776 DOI: 10.1111/jocn.16393] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Revised: 03/11/2022] [Accepted: 05/16/2022] [Indexed: 11/30/2022]
Abstract
BACKGROUND Indwelling urinary catheters (IDUCs) are associated with complications and early removal is therefore essential. Currently, it is unknown what the effect of a specific removal time is and what the consequences of this removal time are. RESEARCH QUESTION To present an overview of the available evidence to determine the effects of three postoperative IDUC removal times (after a certain number of hours, at a specific time of day and flexible removal time) on the development of complications in hospital. METHODS PubMed, Medline, Embase, Emcare and Cochrane Central Register of Controlled Trials were searched till 6 June, 2021. Studies were included that described the effect of the removal time in relation to re-catheterisation, urinary tract infections (UTIs), ambulation time, time of first voiding and hospital stay. The quality of the studies was assessed with the Newcastle-Ottawa Scale and the Cochrane Effective Practice and Organisation of Care. A narrative descriptive analysis was performed. PRISMA guidelines were followed in reporting this review. RESULTS Twenty studies were included from which 18 compared removal after a number of hours, 1 reported on a specific removal time and 1 reported on both topics. The results were contradicting regarding the hypothesis that later removal increases the incidence of UTIs. Earlier removal does not lead to a higher re-catheterisation rate while immediate removal is beneficial for reducing the time to first ambulation and shortening the hospital stay. Studies reporting on specific removal times did not find differences in outcomes. No study addressed flexible removal time. CONCLUSIONS There is inconclusive evidence that earlier removal results in less UTIs, despite the incidence of UTIs increasing if the IDUC is removed ≥24 h. Immediate or after 1-2 day(s) removal does not lead to higher re-catheterisation rates while immediate removal results in earlier ambulation and shorter length of hospital stay. IMPLICATIONS OF KEY FINDINGS Nurses should focus on early IDUC removal while being aware of urinary retention.

Abstract
Urinary tract infections (UTIs) comprise the second most common type of healthcare-associated infections, with up to 80% of UTIs caused by indwelling urinary catheters. Current research suggests that the best way to prevent catheter-associated UTIs (CAUTIs) is to reduce unnecessary catheterisation. Few reviews have focused on the prevalence, risk factors and preventive measures for inappropriate catheterisation. This article, consequently, sought to evaluate the current evidence on the prevalence, risk factors and measures that can be taken to prevent inappropriate urinary catheterisation.

Abstract
INTRODUCTION Chronic urinary retention is a common lower urinary tract disorder, mostly neurogenic or idiopathic in origin. The preferred treatment is clean intermittent urinary self-catheterisation (CISC) four to six times a day. In most European countries, virtually all patients use single use catheters, which is in contrast to several countries where the use of reusable catheters is more common. The available literature on the use of reusable catheters is conflicting and until now, no randomised controlled trial with sufficient power has been performed to investigate if reusable catheters for CISC is as safe as single use catheters. METHODS AND ANALYSIS We described this protocol for a prospective, randomised controlled non-inferiority trial to investigate if the use of reusable catheters is as safe as single use catheters for CISC patients, measured by symptomatic urinary tract infections (sUTIs). Secondary objectives are adverse events due to a sUTI, urethral damage, stone formation, quality of life and patient satisfaction. A cost-effectiveness analysis will also be performed. 456 Participants will be randomised into two groups stratified for age, gender, menopausal status and (non-)neurogenic underlying disorder. The intervention group will replace the reusable catheter set every 2 weeks for a new set and replace the cleaning solution every 24 hours. The control group continues to use its own catheters. The primary outcome (amount of sUTIs from baseline to 1 year) will be tested for non-inferiority. Categorical outcome measures will be analysed using χ2 tests and quantitative outcome variables by t-tests or Mann-Whitney U tests. Two-sided p values will be calculated. ETHICS AND DISSEMINATION This protocol was reviewed and approved by the Medical Ethics Committee of the Erasmus MC (MEC 2019-0134) and will be performed according to the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) checklist for non-inferiority trials. The results of this randomised controlled non-inferiority trial will be published in a peer-reviewed journal and will be publicly available. TRIAL REGISTRATION NUMBER NL8296.

Abstract
AIM In nursing education, innovative approaches are crucial to enhancing students' competence and preparing them to respond to the complex healthcare needs of society. The aim of the current study was to compare the efficacy of the flipped classroom and traditional educational approaches on the acquisition of urinary system knowledge and skill level, and on the motivation and learning strategies of first-year nursing students. METHODS This study was implemented with a single blind and randomized controlled design in the nursing department of a university's faculty of health sciences between December 2018 and December 2019, with 94 first-year undergraduate nursing students (47 in the experimental group adopting a flipped classroom approach, 47 students in the traditional approach control group). The study was conducted over pre-test and posttest phases for both groups. RESULTS The experimental group had higher mean scores than the controls in intrinsic goal orientation, task value, self-efficacy, rehearsal, elaboration, and organization and effort regulation, but lower scores in test anxiety (p < 0.001). The theoretical and skill exam scores of the experimental group were higher than those of the control group (p < 0.001). CONCLUSION The flipped classroom approach was effective for improving urinary system knowledge and skill level, and for the motivation and learning strategies of nursing students. This innovative education approach can be recommended as a student-centered method in nursing education for teaching theoretical knowledge and evidence-based practices.

Abstract
OBJECTIVE The aim of the study was to identify and rank leading healthcare quality and patient safety challenges of general hospitals in Spain. METHODS A novel online cross-sectional survey for hospitals with 150 or more beds carried out between June and September 2018. Sample frame is hospitals of the National Catalogue of Hospitals of the Ministry of Health in Spain (N = 888). Eligibility criteria are quality experts of clinical quality and/or patient safety services of general hospitals with 150 or more beds. Challenges were ranked using a risk priority number (RPN) calculated from the product of severity, frequency, and detectability scores. RESULTS Targeted hospitals were 234. The contact rate was 97.4%, representing 63% of total beds nationwide. One hundred hospitals completed the questionnaire. According to the RPN, the top five challenges were incorrect hand hygiene of health professionals (mean RPN = 334.5, SD = 198.5), ineffective interprofessional communication (mean RPN = 334.3, SD = 169.5), medication errors in transitions of care (mean RPN = 254.0, SD = 151.0), low reporting rates of patient safety incidents and adverse events (mean RPN = 252.3, SD = 176.3), and antimicrobial resistance due to inappropriate use of antibiotics (mean RPN = 243.5, SD = 158.7). CONCLUSIONS This pioneer study of ranking quality and patient safety challenges of hospitals in Spain provides an evidence-based and context-specific foundation for quality improvement decision-making.

Abstract
OBJECTIVE A systematic review on meatal cleaning prior to urinary catheterisation and post catheterisation and reduces the risk catheter-associated urinary tract infections (CAUTIs) and bacteriuria was published in 2017, with further studies undertaken since this time. The objective of this paper is to present an updated systematic review on the effectiveness of antiseptic cleaning of the meatal area for the prevention of CAUTIs and bacteriuria in patients who receive a urinary catheter. DESIGN Systematic review. DATA SOURCES Electronic databases Cochrane Library, PubMed, Embase, The Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline and Academic Search Complete were searched from 1 January 2016 and 29 February 2020. ELIGIBILITY CRITERIA Randomised controlled trials (RCTs) and quasi-experimental studies evaluating the use of antiseptic, antibacterial or non-medicated agents for cleaning the meatal, periurethral or perineal areas before indwelling catheter insertion or intermittent catheterisation or during routine meatal care. DATA EXTRACTION AND SYNTHESIS Data were extracted using the Cochrane Collaboration's data collection form for RCTs and non-RCTs. Data were extracted by one researcher and then checked for accuracy by a second researcher. RESULTS A total of 18 studies were included. Some potential benefit of using antiseptics, compared with non-antiseptics for meatal cleaning to prevent bacteriuria and or CAUTI was identified (OR 0.84, 95% CI 0.69 to 1.02; p=0.071). Antiseptics (chlorhexidine or povidine-iodine) may be of value for meatal cleaning on the incidence of CAUTI, compared with comparator agents (saline, soap or antimicrobial cloths) (OR=0.65, 95% CI 0.42 to 0.99; p=0.047). CONCLUSION There is emerging evidence of the role of some specific antiseptics (chlorhexidine) prior to urinary catheterisation, in reducing CAUTIs, and some potential benefit to the role of antiseptics more generally in reducing bacteriuria.

Abstract
(1) Background: To assess time trends in the incidence and in-hospital outcomes of urinary tract infection (UTI) in older people (≥65 years) in Spain (2001–2018) according to sex and to identify the factors independently associated with in-hospital mortality (IHM). (2) Methods: Using the Spanish National Hospital Database, we analyzed comorbidity, procedures, diagnosis, isolated microorganisms, and outcomes. (3) Results: We included 583,693 admissions (56.76% women). In both sexes, the incidence increased with age over time (p < 0.001). In men and women, the highest IHM was found among the oldest patients (>84 years) with values of 9.16% and 8.6%, respectively. The prevalence of bacteremia increased from 4.61% to 4.98% from 2001 to 2018 (p < 0.001) and sepsis decreased from 3.16% to 1.69% (p < 0.001). The risk of dying increased with age (>84 years) (OR 3.63; 95% CI 3.5–3.78) and with almost all comorbidities. Urinary catheter was a risk factor for women (OR 1.1; 95% CI 1.02–1.18) and protective for men (OR 0.71; 95% CI 0.66–0.76). Isolation of Staphylococcus aureus increased the risk of IHM by 40% among men (OR 1.4; 95% CI 1.28–1.53). After adjusting for confounders, IHM decreased over time. (4) Conclusions: The incidence of UTIs was higher in older patients and increased over time; however, IHM decreased during the same period. Female sex, age, comorbidities, sepsis, and a Staphylococcus aureus isolation increased risk of IHM.

Abstract
Indwelling urinary catheters are considered an important healthcare intervention for many patients. However, these devices must be used with caution because they are associated with a risk of various potential complications such as catheter-associated urinary tract infections (CAUTIs), as well as a financial burden for healthcare organisations. This article outlines the various types of indwelling catheter that are available, explains the reasons for their use, and details the care required to prevent associated complications, particularly CAUTIs.

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
Infection and blockage of indwelling urinary catheters is significant owing to its high incidence rate and severe medical consequences. Bacterial enzymes are employed as targets for small molecular intervention in human bacterial infections. Urease is a metalloenzyme known to play a crucial role in the pathogenesis and virulence of catheter-associated Proteus mirabilis infection. Targeting urease as a therapeutic candidate facilitates the disarming of bacterial virulence without affecting bacterial fitness, thereby limiting the selective pressure placed on the invading population and lowering the rate at which it will acquire resistance. We describe the design, synthesis, and in vitro evaluation of the small molecular enzyme inhibitor 2-mercaptoacetamide (2-MA), which can prevent encrustation and blockage of urinary catheters in a physiologically representative in vitro model of the catheterized urinary tract. 2-MA is a structural analogue of urea, showing promising competitive activity against urease. In silico docking experiments demonstrated 2-MA's competitive inhibition, whilst further quantum level modelling suggests two possible binding mechanisms.

Molecules 2021; 26:E325. [PMID: 33435210 PMCID: PMC7827291 DOI: 10.3390/molecules26020325] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2020] [Revised: 12/25/2020] [Accepted: 12/29/2020] [Indexed: 11/23/2022] Open
Abstract
This research was aimed at the preparation of a hybrid film based on a layered silicate saponite (Sap) with the immobilized photosensitizer phloxine B (PhB). Sap was selected because of its high cation exchange capacity, ability to exfoliate into nanolayers, and to modify different surfaces. The X-ray diffraction of the films confirmed the intercalation of both the surfactant and PhB molecules in the Sap film. The photosensitizer retained its photoactivity in the hybrid films, as shown by fluorescence spectra measurements. The water contact angles and the measurement of surface free energy demonstrated the hydrophilic nature of the hybrid films. Antimicrobial effectiveness, assessed by the photodynamic inactivation on hybrid films, was tested against a standard strain and against methicillin-resistant bacteria of Staphylococcus aureus (MRSA). One group of samples was irradiated (green LED light; 2.5 h) and compared to nonirradiated ones. S. aureus strains manifested a reduction in growth from 1-log10 to over 3-log10 compared to the control samples with Sap only, and defects in S. aureus cells were proven by scanning electron microscopy. The results proved the optimal photo-physical properties and anti-MRSA potential of this newly designed hybrid system that reflects recent progress in the modification of surfaces for various medical applications.

Epidural analgesia for hepatopancreatobiliary operations and postoperative urinary tract infections: an unrecognized association of "best-practices" and adverse outcomes. HPB (Oxford) 2021; 23:71-79.

Abstract
BACKGROUND Thoracic epidural analgesia (TEA) is considered "best-practices" for pain-control following HPB operations. It is unknown if TEA increases the risk of UTI. We sought to examine the association of TEA and UTI following HPB operations. METHODS A retrospective cohort study of patients undergoing elective HPB operations was performed (ACS-NSQIP [2014-2016]). Patients were categorized by TEA utilization. The primary outcome was UTI. Multivariable logistic regression models were created to examine the association of TEA with UTI; including sensitivity and interaction analyses for age and gender. RESULTS Among 28,571 patients included, 5764 (20.2%) had TEA. UTI occurred more frequently with TEA (3.5% vs. 2.2%, p < 0.01). After multivariable analysis, TEA was associated with increased risk of UTI (1.59 [1.34-1.89]); when stratified by age and gender, the association persisted with an incremental increased risk observed in males over 70 years (1.91 [1.41-2.59]). UTI was associated with increased risk of sepsis (16.8% vs. 5.6%, P < 0.001), LOS (9 versus 6 days, P < 0.001) and readmission rates (21.4% vs. 12.3%, P < 0.001). CONCLUSION Despite TEA recommended as a best-practice standard for HPB operations, the increased risk of UTI calls for evaluation of current practices and consideration of alternative strategies for high-risk vulnerable populations - elderly males.

Estimating the Effect of Healthcare-Associated Infections on Excess Length of Hospital Stay Using Inverse Probability-Weighted Survival Curves. Clin Infect Dis 2020; 71:e415-e420. [PMID: 32047916 PMCID: PMC7713691 DOI: 10.1093/cid/ciaa136] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2019] [Accepted: 02/07/2020] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Studies estimating excess length of stay (LOS) attributable to nosocomial infections have failed to address time-varying confounding, likely leading to overestimation of their impact. We present a methodology based on inverse probability-weighted survival curves to address this limitation. METHODS A case study focusing on intensive care unit-acquired bacteremia using data from 2 general intensive care units (ICUs) from 2 London teaching hospitals were used to illustrate the methodology. The area under the curve of a conventional Kaplan-Meier curve applied to the observed data was compared with that of an inverse probability-weighted Kaplan-Meier curve applied after treating bacteremia as censoring events. Weights were based on the daily probability of acquiring bacteremia. The difference between the observed average LOS and the average LOS that would be observed if all bacteremia cases could be prevented was multiplied by the number of admitted patients to obtain the total excess LOS. RESULTS The estimated total number of extra ICU days caused by 666 bacteremia cases was estimated at 2453 (95% confidence interval [CI], 1803-3103) days. The excess number of days was overestimated when ignoring time-varying confounding (2845 [95% CI, 2276-3415]) or when completely ignoring confounding (2838 [95% CI, 2101-3575]). CONCLUSIONS ICU-acquired bacteremia was associated with a substantial excess LOS. Wider adoption of inverse probability-weighted survival curves or alternative techniques that address time-varying confounding could lead to better informed decision making around nosocomial infections and other time-dependent exposures.

Abstract
The insertion of an indwelling urethral urinary catheter is an invasive procedure that is commonly undertaken in healthcare settings. However, there are several risks and potential complications associated with these devices, so their use should be avoided where possible. It is important that nurses are equipped with the necessary knowledge and skills not only to assess if a patient requires a catheter, but also to minimise the risk of associated complications and to understand how these can be managed. This article discusses some of the common complications that can occur with the use of indwelling urinary catheters, including: catheter-associated urinary tract infections; catheter blockages; encrustation; negative pressure; bladder spasm and trauma; and, in men, paraphimosis. It also explains the steps that nurses can take to reduce the risk of these complications and how to manage them effectively.

Abstract
This thematic review was part of a bigger literature review into the effects of short-term urinary catheters on patients who are discharged home from an acute hospital. This integrated review examined the risks associated with short-term urinary catheters. The MEDLINE, British Nursing Index and CINAHL databases were searched for studies published between 2013 and 2018 that researched the effects of short-term urinary catheters on patients. Twelve research studies were included, which showed the presence of short-term indwelling urinary catheters increased the risk of infection, length of hospital stay and mortality rates. Short-term urinary catheters should be strictly monitored and removed as soon as they are not required.

Abstract
Current NHS policy is to reduce the number of catheter-associated urinary tract infections (CAUTIs). To achieve this, guidance suggests reducing the use of catheterisation as much as possible. For those patients requiring catheterisation, Norfolk and Norwich University Hospitals NHS Foundation Trust (NNUH) ensured that a medicinal anaesthetic, antiseptic lubricant containing chlorhexidine and lidocaine was used for all catheterisations. Between 2011 and 2018 the Trust reduced CAUTIs by around 50%. This article discusses catheterisation, national policy in reducing CAUTIs, and how NNUH achieved this reduction.
