Abstract
OBJECTIVES To compare catheter-related outcomes of individuals who received a tunnelled femorally inserted central catheter (tFICC) with those who received a peripherally inserted central catheter (PICC) in the upper extremities. DESIGN A propensity-score matched cohort study. SETTING A 980-bed tertiary referral hospital in South West Sydney, Australia. PARTICIPANTS In-patients referred to the hospital central venous access service for the insertion of a central venous access device. PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome of interest was the incidence of all-cause catheter failure. Secondary outcomes included the rates of catheters removed because of suspected or confirmed catheter-associated infection, catheter dwell and confirmed upper or lower extremity deep vein thrombosis (DVT). RESULTS The overall rate of all-cause catheter failure in the matched tFICC and PICC cohort was 2.4/1000 catheter days (95% CI 1.1 to 4.4) and 3.0/1000 catheter days (95% CI 2.3 to 3.9), respectively, and when compared, no difference was observed (difference -0.63/1000 catheter days, 95% CI -2.32 to 1.06). We found no differences in catheter dwell (mean difference of 14.2 days, 95% CI -6.6 to 35.0, p=0.910); or in the cumulative probability of failure between the two groups within the first month of dwell (p=0.358). No significant differences were observed in the rate of catheters requiring removal for confirmed central line-associated bloodstream infection (difference 0.13/1000 catheter day, 95% CI -0.36 to 0.63, p=0.896). Similarly, no significant differences were found between the groups for confirmed catheter-related DVT (difference -0.11 per 1000 catheter days, 95% CI -0.26 to 0.04, p=1.00). CONCLUSION There were no differences in catheter-related outcomes between the matched cohort of tFICC and PICC patients, suggesting that tFICCs are a possible alternative for vascular access when the veins of the upper extremities or thoracic region are not viable for catheterisation.

Abstract
Medical devices such as venous catheters (VCs) and urinary catheters (UCs) are widely used in the hospital setting. However, the implantation of these devices is often accompanied by complications. About 60 to 70% of nosocomial infections (NIs) are linked to biofilms. The main complication is the ability of microorganisms to adhere to surfaces and form biofilms which protect them and help them to persist in the host. Indeed, by crossing the skin barrier, the insertion of VC inevitably allows skin flora or accidental environmental contaminants to access the underlying tissues and cause fatal complications like bloodstream infections (BSIs). In fact, 80,000 central venous catheters-BSIs (CVC-BSIs)-mainly occur in intensive care units (ICUs) with a death rate of 12 to 25%. Similarly, catheter-associated urinary tract infections (CA-UTIs) are the most commonlyhospital-acquired infections (HAIs) worldwide.These infections represent up to 40% of NIs.In this review, we present a summary of biofilm formation steps. We provide an overview of two main and important infections in clinical settings linked to medical devices, namely the catheter-asociated bloodstream infections (CA-BSIs) and catheter-associated urinary tract infections (CA-UTIs), and highlight also the most multidrug resistant bacteria implicated in these infections. Furthermore, we draw attention toseveral useful prevention strategies, and advanced antimicrobial and antifouling approaches developed to reduce bacterial colonization on catheter surfaces and the incidence of the catheter-related infections.

Abstract
Background Peripheral intravenous catheterization, as well as drug administration through it, represents one of the most performed procedures by the Nursing team and, for that, precautions need to be adopted to offer harm-free care. Objective To verify the association of Nursing professionals' work shift and training time with proper disinfection of intravenous catheter devices in pediatric units. Methods A cross-sectional and analytical study conducted between June and August 2021 in three hospitalization units of a Pediatric Hospital. The inclusion criterion was drug administration via peripheral intravenous catheters performed by Nursing professionals. The data were analyzed according to inferential statistics, adopting p ≤ .05 as significance level. Results There were a total of 385 observations of drug administration procedures. The device was not disinfected in 60.3% of the cases, there was no friction at the suitable time in 86.3%, and the disinfectant was not allowed to dry in 72.5%. The work shift exerted no influence on performance of the disinfection procedure (p = .376). However, longer training time was associated with a lower rate in performing such procedure (p < .001). Conclusion Performing friction below the recommended time can cause a false sense of prevention of catheter-associated bloodstream infection; therefore, training sessions and strategies for adherence to the disinfection procedures should be considered, mainly for professionals with more training time.

Abstract
BACKGROUND Catheter line infection is a common complication within clinical environments, and there is a pressing need for technological options to aid in reducing the possibility of sepsis. The early identification of contamination could be pivotal in reducing cases and improving outcomes. METHOD A sensing rationale based on a riboflavin-modified electrode system integrated within a modified 3D-printed catheter needle-free connector is proposed, which can monitor changes in pH brought about by bacterial contamination. RESULTS Riboflavin, vitamin B2, is a biocompatible chemical that possesses a redox-active flavin core that is pH dependent. The oxidation peak potential of the adsorbed riboflavin responds linearly to changes in pH with a near-Nernstian behavior of 63 mV/pH unit and is capable of accurately monitoring the pH of an authentic IV infusate. CONCLUSIONS The proof of principle is demonstrated with an electrode-printed hub design offering a valuable foundation from which to explore bacterial interactions within the catheter lumen with the potential of providing an early warning of contamination.

Abstract
Background Central line-associated bloodstream infection (CLABSI) is the most common hospital-acquired infection. However, studies evaluating the factors associated with the risk of CLABSI in pediatric intensive care units (PICU) were limited in India. Objective The objective of our study is to evaluate the association of factors and the etiology causing CLABSI. Study design This is a hospital-based single-center prospective study conducted in the pediatric intensive care unit (PICU) of our tertiary care hospital spanning one year. Participants Children aged between two months to 15 years admitted in the PICU for more than 48 hours with central venous catheterization were included. Pearson's chi-squared test with Yates' continuity correction and logistic regression with odds ratio were calculated by R statistical software (R Foundation for Statistical Computing, Vienna, Austria) and a p-value less than 0.05 was considered statistically significant. Results Our analysis showed that factors such as young age (2-12 months), high pediatric risk of mortality (PRISM III) score (> 15), leukocytosis, neutrophilia, anemia, change of central venous catheter, duration of catheterization (>7 days), exposure to blood products, use of steroids, inotropes, and prophylactic antibiotics were significantly associated with increased risk of CLABSIs with an odds ratio of 4.53, 4.54, 2.91, 4.56, 4.76, 3.74, 2.49, 2.41, 7.22, 6.77 and 5.16 respectively (p<0.05). Further, factors such as older age (>12 months) and low PRISM III score (≤ 15) significantly reduce the risk of CLABSIs by 83.64% and 69.14% respectively (p<0.05). Conclusion In conclusion, our results revealed that factors such as young age, high PRISM III score, leukocytosis, neutrophilia, anemia, change of central venous catheter, duration of catheterization (> 7 days), exposure to blood products during the hospital stay, use of steroids, inotropes, and prophylactic antibiotics were identified as risk factors for CLABSI.

Randomized Clinical Trial of the Need for Antibiotic Treatment for Low-Risk Catheter-Related Bloodstream Infection Caused by Coagulase-Negative Staphylococci. Antibiotics (Basel) 2023; 12:antibiotics12050839. [PMID: 37237744 DOI: 10.3390/antibiotics12050839] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Revised: 04/26/2023] [Accepted: 04/27/2023] [Indexed: 05/28/2023] Open
Abstract
According to clinical guidelines, the management of catheter-related bloodstream infections (CRBSI) due to coagulase-negative staphylococci (CoNS) includes catheter removal and antibiotic treatment for 5 to 7 days. However, in low-risk episodes, it remains uncertain whether antibiotic therapy is necessary. This randomized clinical trial aims to determine whether the non-administration of antibiotic therapy is as safe and effective as the recommended strategy in low-risk episodes of CRBSI caused by CoNS. With this purpose, a randomized, open-label, multicenter, non-inferiority clinical trial was conducted in 14 Spanish hospitals from 1 July 2019 to 31 January 2022. Patients with low-risk CRBSI caused by CoNS were randomized 1:1 after catheter withdrawal to receive/not receive parenteral antibiotics with activity against the isolated strain. The primary endpoint was the presence of any complication related to bacteremia or to antibiotic therapy within 90 days of follow-up. The secondary endpoints were persistent bacteremia, septic embolism, time until microbiological cure, and time until the disappearance of a fever. EudraCT: 2017-003612-39 INF-BACT-2017. A total of 741 patients were assessed for eligibility. Of these, 27 were included in the study; 15 (55.6%) were randomized to the intervention arm (non-antibiotic administration) and 12 (44.4%) to the control arm (antibiotic therapy as per standard practice). The primary endpoint occurred in one of the 15 patients in the intervention group (septic thrombophlebitis) and in no patients in the control group. The median time until microbiological cure was 3 days (IQR 1-3) in the intervention arm and 1.25 days (IQR 0.5-2.62) in the control arm, while the median time until fever resolution was zero days in both arms. The study was stopped due to the insufficient number of recruited patients. These results seem to indicate that low-risk CRBSI caused by CoNS can be managed without antibiotic therapy after catheter removal; efficacy and safety are not affected.

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
OBJECTIVES This clinical trial aimed to compare the ultrasound-guided in-plane infraclavicular cannulation of the axillary vein (AXV) and the ultrasound-guided out-of-plane cannulation of the internal jugular vein (IJV). DESIGN A prospective, single-blinded, open label, parallel-group, randomized trial. SETTING Two university-affiliated ICUs in Poland (Opole and Lublin). PATIENTS Mechanically ventilated intensive care patients with clinical indications for central venous line placement. INTERVENTIONS Patients were randomly assigned into two groups: the IJV group ( n = 304) and AXV group ( n = 306). The primary outcome was to compare the IJV group and AXV group through the venipuncture and catheterization success rates. Secondary outcomes were catheter tip malposition and early mechanical complication rates. All catheterizations were performed by advanced residents and consultants in anesthesiology and intensive care. MEASUREMENTS AND MAIN RESULTS The IJV puncture rate was 100%, and the AXV was 99.7% (chi-square, p = 0.19). The catheterization success rate in the IJV group was 98.7% and 96.7% in the AXV group (chi-square, p = 0.11). The catheter tip malposition rate was 9.9% in the IJV group and 10.1% in the AXV group (chi-square, p = 0.67). The early mechanical complication rate in the IJV group was 3% (common carotid artery puncture-4 cases, perivascular hematoma-2 cases, vertebral artery puncture-1 case, pneumothorax-1 case) and 2.6% in the AXV group (axillary artery puncture-4 cases, perivascular hematoma-4 cases) (chi-square, p = 0.79). CONCLUSIONS No difference was found between the real-time ultrasound-guided out-of-plane cannulation of the IJV and the infraclavicular real-time ultrasound-guided in-plane cannulation of the AXV. Both techniques are equally efficient and safe in mechanically ventilated critically ill patients.

Abstract
Tunneled central venous catheter (TCVC) related infection remains a challenge in the care of hemodialysis patients. We aimed to determine the best antimicrobial lock therapy (ALT) to eradicate coagulase-negative staphylococci (CoNS) biofilms. We studied the colonization status of the catheter every 30 days by quantitative blood cultures (QBC) drawn through all catheter lumens. Those patients with a significant culture (i.e.,100 to 1,000 CFU/mL) of a CoNS were classified as patients with a high risk of developing catheter-related bloodstream infections (CRBSI). They were assigned to receive daptomycin, vancomycin, teicoplanin lock solution, or the standard of care (SoC) (i.e., heparin lock). The primary endpoint was to compare eradication ability (i.e., negative QBC for 30 days after ending ALT) rates between different locks and the SoC. A second objective was to analyze the correlation between ALT exposure and isolation of CoNS with antimicrobial resistance. Daptomycin lock was associated with a significant higher eradication success than with the SoC: 85% versus 30% (relative risk [RR] = 14, 95% confidence interval [CI] = 2.4 - 82.7); followed by teicoplanin locks with a 83.3% success (RR = 11.7; 95% CI = 2 - 70.2). We observed CoNs isolates with a higher teicoplanin MIC in patients with repeated teicoplanin locks exposure (coefficient = 0.3; 95% CI = 0.11 - 0.47). However, teicoplanin MICs decreased in patients treated with vancomycin locks (coefficient = -0.56; 95% CI = -0.85 - -0.02). Methicillin-resistance decreased with accumulative ALT (RR = 0.82; 95% CI = 0.69 - 0.98). In this study, daptomycin locks achieve the highest eradication rate of CoNS from hemodialysis catheters in vivo.

[PMID: 36551349 PMCID: PMC9774347 DOI: 10.3390/antibiotics11121692] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 11/21/2022] [Accepted: 11/22/2022] [Indexed: 11/25/2022] Open
Abstract
This study aimed to prove that pre-emptive antimicrobial locks in patients at risk of bacteremia decrease infection. We performed a non-randomized prospective pilot study of hemodialysis patients with tunneled central venous catheters. We drew quantitative blood cultures monthly to detect colonization. Patients with a critical catheter colonization by coagulase-negative staphylococci (defined as counts of 100−999 CFU/mL) were at high risk of developing a catheter-related bloodstream infection. We recommended antimicrobial lock for this set of patients. The nephrologist in charge of the patient decided whether to follow the recommendation or not (i.e., standard of care). We compared bloodstream infection rates between patients treated with antimicrobial lock therapy versus patients treated with the standard of care (i.e., heparin). We enrolled 149 patients and diagnosed 86 episodes of critical catheter colonization by coagulase-negative staphylococci. Patients treated with antimicrobial lock had a relative risk of bloodstream infection of 0.19 when compared with heparin lock (CI 95%, 0.11−0.33, p < 0.001) within three months of treatment. We avoided one catheter-related bloodstream infection for every ten catheter-critical colonizations treated with antimicrobial lock [number needed to treat 10, 95% CI, 5.26−100, p = 0.046]. In conclusion, pre-emptive antimicrobial locks decrease bloodstream infection rates in hemodialysis patients with critical catheter colonization.

Decreased Mortality among Patients with Catheter-Related Bloodstream Infections at Catalan Hospitals (2010-2019). J Hosp Infect 2022; 126:70-77. [PMID: 35594988 DOI: 10.1016/j.jhin.2022.05.009] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Revised: 05/03/2022] [Accepted: 05/09/2022] [Indexed: 11/21/2022]
Abstract
BACKGROUND The incidence of catheter-related bloodstream infections (CRBSI) has fallen over the last decade, especially in intensive care units (ICUs). AIM To assess the existence of concomitant trends in outcomes and to analyse the current risk factors for mortality. METHODS A multicentre retrospective cohort study was conducted at 24 Catalan hospitals participating in the Surveillance of healthcare associated infections in Catalonia (VINCat). All hospital-acquired CRBSI episodes diagnosed from January 2010 to December 2019 were included. A common protocol including epidemiological, clinical and microbiological data was prospectively completed. Mortality at 30 days after bacteraemia onset was analysed using the Cox regression model. FINDINGS Over the study period, 4,795 episodes of CRBSI were diagnosed. Among them, 75% were acquired in conventional wards and central venous catheters were the most frequently involved (61%). The 30-day mortality rate was 13.8%, presenting a significant downward trend over the study period: from 17.9% in 2010 to 10.6% in 2019 (HR 0.95 [0.92-0.98]). The multivariate analysis identified age (HR 1.03 [1.02-1.04]), femoral catheter (HR 1.78 [1.33-2.38]), medical ward acquisition (HR 2.07 [1.62-2.65] and ICU acquisition (HR 3.45 [2.7-4.41]), S. aureus (HR 1.59 [1.27-1.99]) and Candida sp. (HR 2.19 [1.64-2.94]) as risk factors for mortality while the mortality rate associated with episodes originating in peripheral catheters was significantly lower (HR 0.69 [0.54-0.88]). CONCLUSIONS Mortality associated with CRBSI has fallen in recent years but remains high. Intervention programs should focus especially on ICUs and medical wards, where incidence and mortality rates are highest.

Abstract
BACKGROUND To date, central line-associated bloodstream infections (CLABSIs) are the most common healthcare-associated infections in high-risk neonates and children. These infections are associated with significantly longer hospital stays, increased health care cost, and mortality in the health care systems. Application of evidence-based preventive interventions has proven to decrease CLABSI rate. The purpose of this study is to reduce the undesired relative high CLABSI rate through the adoption of standardized quality improvement interventions. METHODS and Methods: The study employed a pre-post-intervention design. Phase one is a retrospective calculation of 12 months of surveillance period as a baseline. Phase 2 establishes a multidisciplinary quality improvement intervention, which includes the formation of a dedicated central line insertion team, provision of central line kit at the bedside, training and educating the team, and selecting bundle checklist. In the third phase, we performed auditing and calculating the checklist compliance and monthly feedback for 12 consecutive post-intervention months. During phase 1 and 3, we calculated the following measures; CLABSI per 1000 catheter-days, duration of central line use, and device utilization ratio. RESULTS During the post-intervention phase the CLABSI rate significantly reduced by 59.5% from 7.5 to 3.0 per 1000 central line day, and the duration of use of the central line decreased from 21.3 ± 9.9 to 11.0 ± 3.2 days (P < 0.05). CONCLUSION Implementation of quality improvement multidisciplinary intervention; central line insertion and maintenance care bundle, dedicated IV team, education and feedback effectively reduced the rate of CLABSI within our pediatrics and neonatal ICUs.

Abstract
Rapid growing mycobacteria have been increasingly recognized as pathogens, both in immunocompromised and immunocompetent population, and their incidence has increased over the last decade significantly. Pulmonary infections are the most common, however, any organ can be affected. The treatment of these infections is costly, prolonged, and often antimicrobial resistance poses a significant challenge to a successful outcome. The source control together with antimicrobials is the cornerstone of treatment. We report a case series of 3 patients with extrapulmonary rapid growing mycobacterial infections in whom the successful treatment was achieved with source control alone.

Abstract
Healthcare-associated infections (HAIs) are caused by nosocomial pathogens. HAIs have an immense impact not only on developing countries but also on highly developed parts of world. They are predominantly device-associated infections that are caused by the planktonic form of microorganisms as well as those organized in biofilms. This review elucidates the impact of HAIs, focusing on device-associated infections such as central line-associated bloodstream infection including catheter infection, catheter-associated urinary tract infection, ventilator-associated pneumonia, and surgical site infections. The most relevant microorganisms are mentioned in terms of their frequency of infection on medical devices. Standard care bundles, conventional therapy, and novel approaches against device-associated infections are briefly mentioned as well. This review concisely summarizes relevant and up-to-date information on HAIs and HAI-associated microorganisms and also provides a description of several useful approaches for tackling HAIs.

Abstract
Purpose of Review While reducing unnecessary days present of central venous catheters (CVCs) is part of central line associated bloodstream infection (CLABSI) best practices, there is limited information regarding compliance with this recommendation as well as addressing barriers to compliance. Recent Findings Significant work has been directed towards daily audits of necessity and improving communication between members of the medical team. Other critical interventions include utilization of the electronic health record (EHR), leadership support of CLABSI reduction goals, and avoiding CVC placement over more appropriate vascular access. Summary Institutions have varied approaches to addressing the issue of removing idle CVCs, and more standardized approaches in checklists as well as communication, particularly on multidisciplinary rounds, will be key to CVC removal. Utilization of the EHR for reminders or appropriate documentation of necessity is a factor. Avoidance of placing a CVC or appropriateness of the CVC is also important to consider.

Abstract
Los isópodos terrestres de Andalucía han sido objeto de numerosos estudios, por lo que el inventario de especies citadas ascendía a 90. En este trabajo se han estudiado 2.046 ejemplares pertenecientes a 41 especies y se ha realizado una revisión bibliográfica de todas las citas anteriores. Como consecuencia, 13 especies se eliminan del inventario original por tratarse de errores en la determinación, porque su estatus como especie es dudoso, o por la carencia en su descripción de rasgos que permitan distinguirlas de otras especies de manera inequívoca. Por tanto, la fauna conocida de isópodos terrestres de Andalucía está formada por 77 especies, pertenecientes a 30 géneros y 11 familias. Para todas ellas se facilita su distribución en Andalucía y una distribución general en el área iberobalear. Se proporcionan datos inéditos para 41 de ellas. Se citan 4 nuevas especies por primera vez para Andalucía, y otras 20 especies para alguna de las provincias andaluzas. La familia Porcellionidae Brandt & Ratzeburg, 1831, con 38 especies, y el género Porcellio Latreille, 1804, con 24 especies, son los que presentan mayor riqueza en la región. A nivel provincial, Málaga con 39 especies conocidas es la más rica, seguida de Cádiz (36) y Almería (34). En Andalucía solamente se conocen 11 especies endémicas de isópodos, el 14% de su fauna, frente al 52% del área iberobalear. De todas las especies citadas, solamente cuatro (5%) son cavernícolas.

Abstract
BACKGROUND Placement of central-venous catheters (CVCs) is an essential practice in the management of hospitalized patients, however, insertion at the commonly used sites has often the potential of inducing major complications. Neverthelss, the impact of specific site central line catheter insertion on catheter-associated bloodstream infections (CLABSIs) has not been clarified yet in the literature. OBJECTIVE The aim of the study was to compare CLABSIs and catheter colonization rates among the three catheter insertion sites: subclavian (SC), internal jugular (IJ) and femoral (FEM) in hospitalized patients. Moreover, to analyze the distribution of pathogens and their antimicrobial resistance profiles at these three sites, concurrently. METHODS We performed a retrospective analysis of data collected prospectively from all catheterized patients at a tertiary care Greek hospital from May 2016 to May 2018. Data was collected on 1414 CVCs and 13,054 CVC-days. RESULTS Τhe incidence of CLABSIs among the three sites was as follows: SC:5.1/1000 catheter/days, IJ: 3.73/1000 catheter/days and FEM: 6.93/1000 catheter/days (p = 0.37). The incidence of colonization was as follows: SC:13.39/1000 catheter/days; IJ:7.34/ 1000 catheter/days; FEM:22.91/1000 catheter/days (p = 0.009). MDROs predominated in both CLABSIs and tip colonizations (59.3 and 61%, respectively) with Acinetobacter baumanii being the predominant pathogen (16/59, 27.1% and 44/144, 30.5%, respectively). The incidence of CLABSIs due to multidrug-resistant organisms (MDROs) was as follows: SC:3.83/1000 catheter days; IJ:1.49/1000 catheter days; FEM:5.86/1000 catheter days (p = 0.04). The incidence of tip colonization by MDROs among the 3 sites was as follows: SC:8.93/1000 catheter/days; IJ:4.48/1000 catheter/days; FEM:12.79/1000 catheter/days (p = 0.06). There was no significant difference in the type of pathogen isolated among site groups for both CLABSIs and tip colonizations. CONCLUSIONS FEM site of catheter insertion was associated with a higher rate of bloodstream infection and catheters' colonization compared to IJ and SC sites. Furthermore, this survey highlights the changing trend of the distribution of frequent pathogens and resistance patterns towards MDR Gram-negative pathogens, underscoring the need for consistent monitoring of antimicrobial resistance patterns of these specific infections.

Abstract
Bacterial biofilms are a leading cause of medical device infections. Staphylococcus epidermidis is commonly responsible for these types of infections. With increasing occurrences of antibacterial resistance, there has been a new push to explore treatment options that augment traditional antibiotic therapies. Here, we show how thermal treatment can be applied to both degrade bacterial biofilms on substrates and impede the proliferation of cells that detach from them. Understanding the response of both surface-adhered and dispersed bacterial cells under thermal stress conditions is a foundational step toward the development of an in situ treatment/remediation method for biofilm growth in medical devices; such an application could use oscillatory flow of heated fluid in a catheter as an adjuvant to antibiotic treatment. The work furthermore provides new insight into the viability of disseminated biofilm material. The biofilm phenotype offers bacterial communities protection from environmental factors, as evidenced by its role in the viability, persistence, and virulence of cells under conditions in which flow is present, such as in riverbeds, industrial piping networks, and the human circulatory system. Here, we examined the hypothesis that temperature—an environmental factor that affects the growth of the Gram-positive bacterium Staphylococcus epidermidis—controls, through dual mechanisms, persistence of this bacterial strain in a shear environment characteristic of the human circulatory system. We demonstrated that temperature and antibiotics impact the surface-adhered biofilm and material disseminated downstream in different ways. Specifically, by means of three-dimensional (3D) confocal and scanning electron microscopy, an increase in surface-adhered biofilm heterogeneity was observed with increasing temperature. Additionally, we found a 4-log decrease in cell viability at the biofilm surface as the perfusate temperature was increased from 37°C to 50°C. Finally, the viability of cell-containing fragments that were disseminated from the substrate was assessed by downstream sampling, culture, and optical density measurement. We found that although temperature decreased the viability of the surface-adhered biofilm, the downstream material remained viable. And yet, in the presence of antibiotics, the growth of disseminated material was nearly completely inhibited, even though the addition of antibiotics had no significant impact on the viability of the surface-adhered biofilm. The mechanism involves both biofilm structural damage, as quantified by morphology of debrided material, and reduced cell viability, as quantified by assay of bacterial cells present in the surface-adherent biofilm and in the downstream effluent. The results potentially identify parameter ranges in which elevated temperature could augment current antibiotic treatment regimens. IMPORTANCE Bacterial biofilms are a leading cause of medical device infections. Staphylococcus epidermidis is commonly responsible for these types of infections.

Abstract
PURPOSE To evaluate dislodgement of tunneled dialysis catheters (TDCs) in de novo (DN) placement with ultrasound versus over-the-wire exchange (OTWE). MATERIALS AND METHODS Data were collected retrospectively on all TDC placements at this institution from 2001 to 2019 and were excluded if no removal date was recorded or if dwell time was more than 365 days. Information on TDC brand, placement, insertion/removal, and removal reason were collected. Multiple logistic regression evaluated factors associated with TDC dislodgement. DN placement and OTWE were compared for rate of dislodgement (generalized estimating equations method) and TDC dwell time (survival analysis). RESULTS In total, 5328 TDCs were included with 66% (3522) placed DN and 32% (1727) via OTWE. Mean dwell time was 65 ± 72 days, and dislodgement occurred in 4% (224). TDC dislodgement rates in the DN and OTWE groups were 0.48 and 0.93 per 1000 catheter days, respectively. Brand (Ash Split vs. VectorFlow), placement technique (OTWE vs. DN), laterality (left vs. right), and site (left vs. right internal jugular vein) were significant predictors of dislodgement. OTWE placement exhibited 1.7 times the odds of dislodgement (95% confidence interval, 1.2-2.6; P = .004) compared to DN and had significantly higher probability of dislodgement across time (hazard ratio = 2.0; P < .001) compared to DN. Dislodgement rates for OTWE vs. DN were 8% vs. 3% (3 months), 13% vs. 6% (6 months), and 38% vs. 17% (1 year). CONCLUSIONS TDC spontaneous dislodgement rates were significantly and consistently higher after OTWE compared to DN placement. These data support more careful attention to catheter fixation after OTWE placement.

Abstract
Background There is a need to generate accurate data on temporal trends in incidence rates, aetiology and antimicrobial susceptibility of central line-associated bloodstream infections (CLABSIs) in the Indian setting. Aim To study the incidence, aetiology and antimicrobial susceptibility of CLABSI in adult, paediatric and neonatal intensive care units (NICUs) in a tertiary care private hospital in Mumbai, India. Materials and Methods This is a prospective observational study conducted at the adult, paediatric and NICUs of tertiary care private hospital from 2011 to 2018. CLABSI was defined as per the Centers for Disease Control criteria. Surveillance of CLABSI in the intensive care units (ICUs) was conducted using a form adapted from the International Nosocomial Infection Control Consortium surveillance system. The incidence rates of CLABSI (per 1000 central line days), crude mortality, aetiology and antimicrobial susceptibility were calculated and reported. Results Six hundred and eighty-six episodes of CLABSI were recorded, and the overall incidence of CLABSI was 5/1000 catheter days, 4.1 in the adult ICU, 5 in the paediatric ICU and 9 in the newborn ICU. Crude mortality in patients with CLABSI in the adult, paediatric and NICUs was 45%, 30% and 7%, respectively. Of the 752 isolates, 80% were Gram negative, 10% Gram positive and 10% yeast. The prevalence of extended-spectrum beta-lactamase producers was 80%, and rates of carbapenem resistance were on an average 50%. Conclusions The CLABSI rates at a well-equipped tertiary care hospital are still significantly higher than the USA benchmarks. Alarming rates of drug resistance in Gram-negative pathogens were seen.
