Infect Control Hosp Epidemiol 2024; 45:576-582. [PMID: 38213184 PMCID: PMC11027082 DOI: 10.1017/ice.2023.285] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Revised: 11/08/2023] [Accepted: 11/28/2023] [Indexed: 01/13/2024]
Abstract
BACKGROUND Needleless connectors (NCs) can be disinfected using antiseptic barrier caps (ABCs) to reduce the risk of catheter-related bloodstream infections. However, recent evidence suggests that isopropanol can leak from the ABC into the NC, posing concern about their safe use. We sought to determine in vitro which ABC and NC parameters influence the leakage of isopropanol through the infusion circuit. METHODS We assessed 13 NCs and 4 ABCs available in the European market. In vitro circuits consisting of an isopropanol cap, a NC, and an 11-cm catheter line were created. The circuits were left in place for 1 to 7 days at room temperature to assess the kinetics of isopropanol leakage. Isopropanol content in ABC and in circuit flushing solutions (5 mL NaCl 0.9%) after exposure to the cap were measured using gas chromatography with a flame ionization detector. RESULTS The leakage of isopropanol from the cap to the NC was dependent on the NC, but not the cap. The NC mechanism did not predict the leakage of isopropanol. The Q-Syte NC exhibited the most isopropanol leakage (7.01±1.03 mg and 28.32±2.62 mg at 24 hours and 7 days, respectively), whereas the Caresite NC had the lowest isopropanol leakage at 7 days (1.69±0.01 mg). CONCLUSION The use of isopropanol ABCs can cause isopropanol leakage into the catheter circuit according to NC parameters. Caution should be exercised when using these devices, especially in the pediatric and neonatal population.

Abstract
BACKGROUND Reliable and safe venous access is crucial for patients using central venous catheters (CVC). However, such CVCs carry a risk for central line-associated bloodstream infections (CLABSIs). Antiseptic barrier caps (ABCs) are a novel tool in the armamentarium for CVC disinfection. Our aim was to review the efficacy and safety of ABCs. METHOD A literature search was conducted using PubMed, EMBASE, Cochrane library, and CINAHL. Primary aim was to compare CLABSI rates in patients using ABCs versus standard care. Secondary aims included efficacy of ABCs in relevant subgroups (age, ABC brand, clinical setting), safety, compliance, and costs. Fifteen studies were included in the meta-analysis. RESULTS In total, 391 CLABSIs in 273,993 catheter days occurred in the intervention group versus 620 CLABSIs in 284,912 days in the standard care group, resulting in a risk ratio of 0.65 (95%CI 0.55-0.76; P<0.00001). Subgroup analyses showed similar effects, except for non-intensive care unit. In general, ABCs were safe, highly appreciated by patients and caregivers, and cost-effective, while compliance was easy to monitor. In most studies, a substantial risk of bias was observed. CONCLUSION In conclusion, while available evidence suggests that ABCs are effective, safe, easy in use, and cost-effective. However, due to the poor methodological quality of most available studies, more robust data should justify their use at this point.

Abstract
Central venous access is an essential aspect of critical care for pediatric patients. In the critically ill pediatric population, image-guided procedures performed at the bedside expedite care and may reduce risks and logistical challenges associated with patient transport to a remote procedure suite such as interventional radiology. We describe our institutional technique for ultrasound-guided tunneled femoral venous access in neonates and infants and provide technical pearls from our experience, with an intended audience including specialists performing point-of-care ultrasound-guided procedures as well as interventional radiologist making their services available in the intensive care unit.

Abstract
Background Current evidence regarding the efficacy of ethanol locks in preventing catheter-related bloodstream infection (CRBI) is inconclusive. Methods Electronic databases, including PubMed, Web of Science, Embase, and the Cochrane Library (until April 2018),were systematically searched for relevant studies. Two reviewers independently screened the retrieved records and identified RCTs that met the inclusion criteria. Relevant data were extracted for pooled analyses using Review Manager 5.3 software. Subgroup analysis was performed according to the study quality, duration of the ethanol lock, disease type and CRBI definition. Eggs’ method was applied to detect publication bias. Sensitivity analysis was conducted to check the stability of the meta-analysis results. Results Ten RCTs involving 2760 patients were included in the analysis. The overall pooled result indicated that ethanol locks significantly reduced the incidence of CRBI (RR 0.66, 95% CI 0.51–0.86). Subgroup analysis suggested that an ethanol lock significantly decreased the incidence of CRBI in patients with hematological diseases (RR 0.50, 95% CI 0.31–0.80). An ethanol lock significantly reduced the incidence of CRBI in a2-hour ethanol lock group (RR 0.49, 95% CI 0.33–0.73). The meta-analysis showed that an ethanol lock significantly reduced the incidence of CRBI according to analysis of high-(RR 0.66, 95% CI 0.47–0.94) or low-(RR 0.66, 95% CI 0.46–0.95) quality studies. Meta-analysis of studies with a strict CRBI definition showed that an ethanol lock can significantly prevent CRBI (RR 0.61, 95% CI 0.42–0.89). The results of sensitivity analysis suggested that the pooled result was stable. Meta-analysis of adverse events showed that an ethanol lock did not increase the incidence of thrombosis (RR 1.05, 95% CI 0.51–2.18) or mortality (RR 0.99, 95% CI 0.90–1.08) but did result in increased nausea (RR 1.54, 95% CI 1.01–2.35), dizziness (RR 4.21, 95% CI 2.40–7.39),elevated blushing rates (RR 3.27, 95% CI 2.05–5.22) and altered taste rates (RR 2.61, 95% CI 1.93–3.54). Conclusions An ethanol lock may play a role in the prevention of CRBI, especially in immunocompromised patients with hematological diseases.

Abstract
Objective Catheter-related blood stream infection (CRBI) is a major cause of morbidity and mortality, and is a source of significant healthcare expenditures in patients that require central venous catheters for intravenous nutrition, chemotherapy, and other products. The source of many catheter-related infections is contamination of the catheter hub. Herein an antimicrobial catheter cap, the AB Cap is described. Methods The AB Cap device is a catheter cleaning device designed to keep needleless luer valves clean by encapsulating them in a cleaning solution. This device was evaluated using an in vitro model of hub contamination with Staphylococcus aureus, Staphylococcus epidermidis (S. epidermidis), Klebsiella pneumonia (K. pneumonia), Pseudomonas aeruginosa, Escherichia coli and Candida albicans (C. albicans). Following hub contamination on days 1, 3, 5 and 7, saline was infused through the AB Cap and effluent collected from the efferent end. The effluent fluid was cultured for the index organisms, and allowed to incubate in culture for up to 7 days. Negative control caps were not contaminated and positive controls lacked cleaning solution and were contaminated. Results Microbial growth developed for all index organisms, and generally within 1 day of culture growth following the first day of contamination (day 1) in effluent from all positive controls, while no growth occurred in effluent from negative controls. No growth of any organism occurred in any of the test items after the first day of contamination. Growth of three organisms was detected in two of the three test AB Caps following contamination day 3, after 1–4 days of incubation. All organisms could be cultured in the effluent from two of the three test items at contamination day 5, generally by the second day of incubation. One test item remained free of growth for the entire test period except for one organism. By day 7, this particular test item grew an additional organism and the testing was concluded. All positive growth test items remained positive on subsequent inoculations during culture of newly obtained effluent with the exception of test item A, from which effluent following inoculation on day 3 showed growth of S. epidermidis and K. pneumonia, but no growth for these organisms from effluent obtained on inoculation day 5. In addition, effluent from test item C showed growth of C. albicans from inoculation day 5, but no growth from effluent obtained on inoculation day 7. The growth of S. epidermidis from effluent of test item A from the day 3 inoculation, and C. albicans from effluent of test items B and C did not occur until day 4 of incubation, suggesting a very small amount of contamination. Conclusion An antimicrobial catheter cap is not a complete substitute for a proper catheter cleaning technique and other anti-infection precautions. However, we describe a unique catheter cap that significantly decreased the likelihood of a catheter-related infection from a non-cleaned cap in an in vitro model.

Abstract
Central venous catheters are often necessary in the pediatric population. Access may be challenging, and each vessel presents its own unique set of risks and complications. Central venous catheterization is useful for hemodynamic monitoring, rapid fluid infusion, and administration of hyperosmolar medications, including vasopressors, antibiotics, chemotherapy, and parenteral nutrition. Recent advances have improved the catheters used as well as techniques for insertion. A serious complication of central access is infection, which is associated with morbidity, mortality, and significant financial costs. Reduction of catheter-related bloodstream infections is realized with use of ethanol locks, single lumens when appropriate, and prudent adherence to insertion and maintenance bundles. Ultrasound guidance used for central venous catheter placement improves accuracy of placement, reducing time and unsuccessful insertion and complication rates. Patients with central venous catheters are best served by multidisciplinary team involvement.

Abstract
Staphylococcus aureus is a major human pathogen that causes a wide range of clinical infections. It is a leading cause of bacteremia and infective endocarditis as well as osteoarticular, skin and soft tissue, pleuropulmonary, and device-related infections. This review comprehensively covers the epidemiology, pathophysiology, clinical manifestations, and management of each of these clinical entities. The past 2 decades have witnessed two clear shifts in the epidemiology of S. aureus infections: first, a growing number of health care-associated infections, particularly seen in infective endocarditis and prosthetic device infections, and second, an epidemic of community-associated skin and soft tissue infections driven by strains with certain virulence factors and resistance to β-lactam antibiotics. In reviewing the literature to support management strategies for these clinical manifestations, we also highlight the paucity of high-quality evidence for many key clinical questions.

Abstract
The “Guideline for Prevention of Intravascular Device-Related Infections” is designed to reduce the incidence of intravascular device-related infections by providing an over view of the evidence for recommendations considered prudent by consensus of Hospital Infection Control Practices Advisor y Committee (HICPAC) members. This two-part document updates and replaces the previously published Centers for Disease Control's (CDC) Guideline for Intravascular Infections (Am J Infect Control1983;11:183-199). Part I, “Intravascular Device-Related Infections: An Over view” discusses many of the issues and controversies in intravascular-device use and maintenance. These issues include definitions and diagnosis of catheter-related infection, appropriate barrier precautions during catheter insertion, inter vals for replacement of catheters, intravenous (IV) fluids and administration sets, catheter-site care, the role of specialized IV personnel, and the use of prophylactic antimi-crobials, flush solutions, and anticoagulants. Part II, “Recommendations for Prevention of Intravascular Device-Related Infections” provides consensus recommendations of the HICPAC for the prevention and control of intravascular device-related infections. A working draft of this document also was reviewed by experts in hospital infection control, internal medicine, pediatrics, and intravenous therapy. However, all recommendations contained in the guideline may not reflect the opinion of all reviewers.

Abstract
National evidence-based guidelines for preventing healthcare-associated infections (HCAI) in National Health Service (NHS) hospitals in England were originally commissioned by the Department of Health and developed during 1998-2000 by a nurse-led multi-professional team of researchers and specialist clinicians. Following extensive consultation, they were first published in January 2001(1) and updated in 2007.(2) A cardinal feature of evidence-based guidelines is that they are subject to timely review in order that new research evidence and technological advances can be identified, appraised and, if shown to be effective for the prevention of HCAI, incorporated into amended guidelines. Periodically updating the evidence base and guideline recommendations is essential in order to maintain their validity and authority. The Department of Health commissioned a review of new evidence and we have updated the evidence base for making infection prevention and control recommendations. A critical assessment of the updated evidence indicated that the epic2 guidelines published in 2007 remain robust, relevant and appropriate, but some guideline recommendations required adjustments to enhance clarity and a number of new recommendations were required. These have been clearly identified in the text. In addition, the synopses of evidence underpinning the guideline recommendations have been updated. These guidelines (epic3) provide comprehensive recommendations for preventing HCAI in hospital and other acute care settings based on the best currently available evidence. National evidence-based guidelines are broad principles of best practice that need to be integrated into local practice guidelines and audited to reduce variation in practice and maintain patient safety. Clinically effective infection prevention and control practice is an essential feature of patient protection. By incorporating these guidelines into routine daily clinical practice, patient safety can be enhanced and the risk of patients acquiring an infection during episodes of health care in NHS hospitals in England can be minimised.

Abstract
PURPOSE To develop an evidence-based guideline on central venous catheter (CVC) care for patients with cancer that addresses catheter type, insertion site, and placement as well as prophylaxis and management of both catheter-related infection and thrombosis. METHODS A systematic search of MEDLINE and the Cochrane Library (1980 to July 2012) identified relevant articles published in English. RESULTS The overall quality of the randomized controlled trial evidence was rated as good. There is consistency among meta-analyses and guidelines compiled by other groups as well. RECOMMENDATIONS There is insufficient evidence to recommend one CVC type or insertion site; femoral catheterization should be avoided. CVC should be placed by well-trained providers, and the use of a CVC clinical care bundle is recommended. The use of antimicrobial/antiseptic-impregnated and/or heparin-impregnated CVCs is recommended to decrease the risk of catheter-related infections for short-term CVCs, particularly in high-risk groups; more research is needed. The prophylactic use of systemic antibiotics is not recommended before insertion. Data are not sufficient to recommend for or against routine use of antibiotic flush/lock therapy; more research is needed. Before starting antibiotic therapy, cultures should be obtained. Some life-threatening infections require immediate catheter removal, but most can be treated with antimicrobial therapy while the CVC remains in place. Routine flushing with saline is recommended. Prophylactic use of warfarin or low-molecular weight heparin is not recommended, although a tissue plasminogen activator (t-PA) is recommended to restore patency to occluded catheters. CVC removal is recommended when the catheter is no longer needed or if there is a radiologically confirmed thrombosis that worsens despite anticoagulation therapy.

Abstract
PURPOSE OF REVIEW Regional anesthesia is commonly used to provide intraoperative anesthesia and postoperative analgesia. Potential complications of both neuraxial and peripheral regional techniques include infectious sequelae. This review examines important components of practice that are known to minimize the risk of infection associated with regional anesthesia. RECENT FINDINGS Healthcare-associated infections increase morbidity and mortality, patient pain and suffering, direct medical costs, and hospital length-of-stay. Recently published national guidelines from subspecialty societies and government agencies emphasize the importance of strict aseptic technique in the prevention of infectious complications associated with regional anesthesia. Proper hand hygiene, the use of surgical masks, appropriate antiseptic selection and application, and proper preparation of local anesthetic infusate solutions are all considered essential components of asepsis. Anesthesia providers need to adhere to strict aseptic guidelines to minimize the risk of potentially devastating infectious complications. SUMMARY Infectious complications associated with regional anesthesia are exceedingly rare events. Adherence to strict aseptic guidelines as published by the American Society of Regional Anesthesia and Pain Medicine, American Society of Anesthesiologists, and the Royal College of Anaesthetists may reduce the risk of infectious complications.

Abstract
PN (parenteral nutrition) should be standardised to ensure quality and to reduce complications, and it should be carried out in consultation with a specialised nutrition support team whenever possible. Interdisciplinary nutrition support teams should be established in all hospitals because effectiveness and efficiency in the implementation of PN are increased. The tasks of the team include improvements of quality of care as well as enhancing the benefit to cost ratio. Therapeutic decisions must be taken by attending physicians, who should collaborate with the nutrition support team. “All-in-One” bags are generally preferred for PN in hospitals and may be industrially manufactured, industrially manufactured with the necessity to add micronutrients, or be prepared “on-demand” within or outside the hospital according to a standardised or individual composition and under consideration of sterile and aseptic conditions. A standardised procedure should be established for introduction and advancement of enteral or oral nutrition. Home PN may be indicated if the expected duration of when PN exceeds 4 weeks. Home PN is a well established method for providing long-term PN, which should be indicated by the attending physician and be reviewed by the nutrition support team. The care of home PN patients should be standardised whenever possible. The indication for home PN should be regularly reviewed during the course of PN.

Abstract
OBJECTIVES Increased incidence of cancers and the development of totally implanted venous access devices that contain their own port to deliver chemotherapy will lead to a greater than before numbers of central venous catheter related thrombosis (CVCT). Medical consequences include catheter dysfunction and pulmonary embolism. Compared with lower extremity deep venous thrombosis (DVT) (3 d) and with non CVC associated thrombosis (5 d), CVCT is associated with an increased duration of hospitalisation (9 d). CVCT oftentimes leads to the need to replace such ports at an average cost of 4500 euros. CURRENT KNOWLEDGE AND KEY POINTS Vessel injury caused by the procedure of CVC insertion is the most important risk factor for development of CVCT. This event could cause the formation of a fresh thrombus, which is reversible in the large majority of patients. The incidence of CVC-related DVT assessed by venography has been reported to vary from 30 to 60% but catheter-related DVT in adult patients is symptomatic in only 5% of cases. The majority of patients with CVC-related DVT is asymptomatic or has non-specific symptoms: arm or neck swelling or pain, distal paresthesias, headache, congestion of subcutaneous collateral veins. In the case of clinical suspicion of CVC-related DVT, compressive ultrasonography (US), especially with Doppler and color imaging, currently is first used to confirm the diagnosis. The main criteria of color-Doppler US are visualization of mural thrombi or incompressibility of the veins. Consequently, contrast venography is reserved for clinical trials and difficult diagnostic situations. There is no consensus on the optimal management of patients with CVC-related DVT. Treatment of CVC-related VTE requires a 5- to 7-day course of adjusted-dose unfractionated heparin or LMWH followed by oral anticoagulants. Long-term LMWH that has been shown to be more effective than oral anticoagulant in cancer patients with lower limb DVT could be used in these patients. The optimal duration of oral anticoagulation treatment for CVC-related DVT is unknown, but patients with active cancer should be treated for at least 6 months or indefinitely. FUTURE PROSPECTS AND PROJECTS The efficacy and safety of pharmacologic prophylaxis for CVC related thrombosis is not established. Additional studies performed in high risk populations are needed to define if LMWH or oral anticoagulation is indicated in this clinical setting.

Abstract
Central venous access plays an important role in the management of an ever-increasing population of patients ranging from those that are critically ill to patients with difficult clinical access. Interventional radiologists are key in delivering this service and should be familiar with the wide range of techniques and catheters now available to them. A comprehensive description of these catheters with regard to indications, technical aspects of catheterization, success rates, and associated early and late complications, as well as a review of various published guidelines on central venous catheter insertion are given in this article.

Abstract
National evidence-based guidelines for preventing healthcare-associated infections (HCAI) in National Health Service (NHS) hospitals in England were commissioned by the Department of Health (DH) and developed during 1998-2000 by a nurse-led multi-professional team of researchers and specialist clinicians. Following extensive consultation, they were published in January 2001. These guidelines describe the precautions healthcare workers should take in three areas: standard principles for preventing HCAI, which include hospital environmental hygiene, hand hygiene, the use of personal protective equipment, and the safe use and disposal of sharps; preventing infections associated with the use of short-term indwelling urethral catheters; and preventing infections associated with central venous catheters. The evidence for these guidelines was identified by multiple systematic reviews of experimental and non-experimental research and expert opinion as reflected in systematically identified professional, national and international guidelines, which were formally assessed by a validated appraisal process. In 2003, we developed complementary national guidelines for preventing HCAI in primary and community care on behalf of the National Collaborating Centre for Nursing and Supportive Care (National Institute for Healthand Clinical Excellence). A cardinal feature of evidence-based guidelines is that they are subject to timely review in order that new research evidence and technological advances can be identified, appraised and, if shown to be effective in preventing HCAI, incorporated into amended guidelines. Periodically updating the evidence base and guideline recommendations is essential in order to maintain their validity and authority. Consequently, the DH commissioned a review of new evidence published following the last systematic reviews. We have now updated the evidence base for making infection prevention and control recommendations. A critical assessment of the updated evidence indicated that the original epic guidelines published in 2001 remain robust, relevant and appropriate but that adjustments need to be made to some guideline recommendations following a synopsis of the evidence underpinning the guidelines. These updated national guidelines (epic2) provide comprehensive recommendations for preventing HCAI in hospitals and other acute care settings based on the best currently available evidence. Because this is not always the best possible evidence, we have included a suggested agenda for further research in each section of the guidelines. National evidence-based guidelines are broad principles of best practice which need to be integrated into local practice guidelines. To monitor implementation, we have suggested key audit criteria for each section of recommendations. Clinically effective infection prevention and control practice is an essential feature of protecting patients. By incorporating these guidelines into routine daily clinical practice, patient safety can be enhanced and the risk of patients acquiring an infection during episodes of healthcare in NHS hospitals in England can be minimised.

Abstract
BACKGROUND/AIMS Total parenteral nutrition (TPN) has proven a tremendous advance in all disciplines in medicine but itself introduces a spectrum of possible complications related to both the parenteral nutritional solution as well as the technique of intravenous delivery. Our aim is to review the specific complications of TPN. MATERIALS AND METHODS This article presents a critical literature review of relevant topics in TPN-related complications-metabolic, infections, and nutrition related. RESULTS Special emphasis focuses on complications of TPN arising from thrombosis or infectious sequelae related to the central venous catheterization and metabolic complications involving the kidneys, bones, liver, and biliary tract. CONCLUSIONS Awareness and surveillance of TPN-related complications can prevent, potentially, some of these complications related to parenteral nutritional support.

Abstract
OBJECTIVE To better understand the absolute and relative risks of bloodstream Infection (BSI) associated with the various types of intravascular devices (IVDs), we analyzed 200 published studies of adults In which every device in the study population was prospectively evaluated for evidence of associated infection and microbiologically based criteria were used to define IVD-related BSI. METHODS English-language reports of prospective studies of adults published between January 1, 1966, and July 1, 2005, were identified by MEDLINE search using the following general search strategy: bacteremla [Medical Subject Heading, MeSH] OR septicemia [MeSH] OR bloodstream Infection AND the specific type of intravascular device (e.g., central venous port). Mean rates of IVD-related BSI were calculated from pooled data for each type of device and expressed as BSIs per 100 IVDs (%) and per 1000 IVD days. RESULTS Point incidence rates of IVD-related BSI were lowest with peripheral Intravenous catheters (0.1%, 0.5 per 1000 IVD-days) and midline catheters (0.4%, 0.2 per 1000 catheter-days). Far higher rates were seen with short-term noncuffed and nonmedicated central venous catheters (CVCs) (4.4%, 2.7 per 1000 catheter-days). Arterial catheters used for hemodynamic monitoring (0.8%, 1.7 per 1000 catheter-days) and peripherally inserted central catheters used in hospitalized patients (2.4%, 2.1 per 1000 catheter-days) posed risks approaching those seen with short-term conventional CVCs used in the Intensive care unit. Surgically implanted long-term central venous devices--cuffed and tunneled catheters (22.5%, 1.6 per 1000 IVD-days) and central venous ports (3.6%, 0.1 per 1000 IVD-days)--appear to have high rates of Infection when risk Is expressed as BSIs per 100 IVDs but actually pose much lower risk when rates are expressed per 1000 IVD-days. The use of cuffed and tunneled dual lumen CVCs rather than noncuffed, nontunneled catheters for temporary hemodlalysis and novel preventive technologies, such as CVCs with anti-infective surfaces, was associated with considerably lower rates of catheter-related BSI. CONCLUSIONS Expressing risk of IVD-related BSI per 1000 IVD-days rather than BSIs per 100 IVDs allows for more meaningful estimates of risk. These data, based on prospective studies In which every IVD in the study cohort was analyzed for evidence of infection by microbiologically based criteria, show that all types of IVDs pose a risk of IVD-related BSI and can be used for benchmarking rates of infection caused by the various types of IVDs In use at the present time. Since almost all the national effort and progress to date to reduce the risk of IVD-related Infection have focused on short-term noncuffed CVCs used in Intensive care units, Infection control programs must now strive to consistently apply essential control measures and preventive technologies with all types of IVDs.

Abstract
OBJECTIVE Inhibition of fibrin sheath formation by enoxaparin decreases catheter colonization. Fibrin-binding radioactive tracer and catheter weights quantify fibrin reduction. DESIGN Controlled experimental study of central venous line colonization. SETTING Animal laboratory. SUBJECTS Adult male Sprague-Dawley rats. INTERVENTIONS Central venous lines were introduced into right external jugular veins of 254 animals in three groups: enoxaparin, Fibrimage, and catheter weight. The enoxaparin group (n = 196) received daily enoxaparin injections (n = 97) or catheter implantation only (n = 99); 176 received tail vein injections of Staphylococcus epidermidis on postoperative day (POD) 10. Twenty rats received saline injections as a control. On POD 13, catheters were removed and incubated in broth at 37 degrees C for 48 hrs. Turbid samples were plated. In the Fibrimage group (n = 39), 20 rats receiving enoxaparin were compared with 19 controls without enoxaparin; all received S. epidermidis injections on POD 10. Fibrimage, fibrin-binding radiolabeled tracer, was given 1 hr before catheter removal. In the weight group (n = 19), six rats received enoxaparin; 13 did not. All received injections of S. epidermidis on POD 10. MEASUREMENTS AND MAIN RESULTS Positive plates underwent analytic profile index testing, ensuring correlation with inoculum. Results were compared using Fisher's exact or chi-square tests. Gamma counts were determined in the Fibrimage group. Catheter tip weights were recorded. Results from the Fibrimage and weight groups were compared using Student's t-test. The enoxaparin group had fewer catheters colonized (17 of 77) vs. no enoxaparin (42 of 99; p < .01). Pericatheter sheaths contained less fibrin compared with controls. Fibrimage group gamma counts were significantly decreased for the enoxaparin subgroup (x = 2244 counts per minute) vs. controls (x = 3767 counts per minute; p < .0002). The weight of catheter tips treated with enoxaparin (x = 39 mg) vs. controls (x = 90 mg) was also significantly decreased (p < .0001). CONCLUSIONS Enoxaparin decreases the amount of fibrin surrounding central venous catheters. The incidence of catheter colonization decreases when the amount of fibrin within the pericatheter sheath decreases.

Abstract
OBJECTIVE We sought to compare the impact of antimicrobial impregnation to that of tunneling of long-term central venous catheters on the rates of catheter colonization and catheter-related bloodstream infection. SUMMARY BACKGROUND DATA Tunneling of catheters constitutes a standard of care for preventing infections associated with long-term vascular access. Although antimicrobial coating of short-term central venous catheters has been demonstrated to protect against catheter-related bloodstream infection, the applicability of this preventive approach to long-term vascular access has not been established. METHODS A prospective, randomized clinical trial in 7 university-affiliated hospitals of adult patients who required a vascular access for > or = 2 weeks. Patients were randomized to receive a silicone central venous catheter that was either impregnated with minocycline and rifampin or tunneled. The occurrence of catheter colonization and catheter-related bloodstream infection was determined. RESULTS Of a total of 351 inserted catheters, 346 (186 antimicrobial-impregnated and 160 tunneled) were analyzed for catheter-related bloodstream infection. Clinical characteristics were comparable in the 2 study groups, but the antimicrobial-impregnated catheters remained in place for a shorter period of time (mean, 30.2 versus 43.8 days). Antimicrobial-impregnated catheters were as likely to be colonized as tunneled catheters (7.9 versus 6.3 per 1000 catheter-days). Bloodstream infection was 4 times less likely to originate from antimicrobial-impregnated than from tunneled catheters (0.36 versus 1.43 per 1000 catheter-days). CONCLUSIONS Antimicrobial impregnation of long-term central venous catheters may help obviate the need for tunneling of catheters.

Abstract
BACKGROUND Central venous catheters (CVCs) are essential for the intensive care of patients with haematological illness. Catheter-related infections (CRI) are an important problem in modern medicine, which may lead to life-threatening situations, to prolonged hospitalisation and increased cost. In immunocompromised patients suffering from haemato-oncological diseases, CRI is a significant factor for adverse outcome. Several clinical studies have shown that CVCs coated with antiseptics such as chlorhexidine and silver-sulfadiazine (CHSS) reduce the risk of catheter-related bacteraemia. Most studies, however, were performed on intensive care patients not suffering from chemotherapy-induced immunosuppression. PATIENTS AND METHODS A prospective double-blind, randomised, controlled trial was performed to investigate the effectiveness of CHSS-coated catheters in haemato-oncological patients. A total number of 184 catheters (median duration of placement, 11 days) were inserted into 184 patients (male 115, female 69), of which 90 were antiseptically coated. After removal, all catheters were investigated for bacterial growth. MAIN RESULTS Catheters coated with CHSS were effective in reducing the rate of significant bacterial growth on either the tip or subcutaneous segment (26%) compared to control catheters (49%). The incidence of catheter colonisation was also significantly reduced (12% coated vs 33% uncoated). Data obtained show a significant reduction of catheter colonisation in CHSS catheters. There was no significant difference in the incidence of catheter-related bacteraemia (3% coated vs 7% uncoated). However, due to the overall low rate of CRI, we could not observe a significant reduction in the incidence of catheter-related bacteraemia. CONCLUSION Our data show that the use of CHSS catheters in patients with haematological malignancy reduces the overall risk of catheter colonisation and CRI, although the incidence of catheter-related bacteremia was similar in both groups.

Abstract
The clinical usefulness of hemodialysis catheters is limited by increased infectious morbidity and mortality. Topical antiseptic agents, such as mupirocin, are effective at reducing this risk but have been reported to select for antibiotic-resistant strains. The aim of the present study was to determine the efficacy and the safety of exit-site application of a standardized antibacterial honey versus mupirocin in preventing catheter-associated infections. A randomized, controlled trial was performed comparing the effect of thrice-weekly exit-site application of Medihoney versus mupirocin on infection rates in patients who were receiving hemodialysis via tunneled, cuffed central venous catheters. A total of 101 patients were enrolled. The incidences of catheter-associated bacteremias in honey-treated (n = 51) and mupirocin-treated (n = 50) patients were comparable (0.97 versus 0.85 episodes per 1000 catheter-days, respectively; NS). On Cox proportional hazards model analysis, the use of honey was not significantly associated with bacteremia-free survival (unadjusted hazard ratio, 0.94; 95% confidence interval, 0.27 to 3.24; P = 0.92). No exit-site infections occurred. During the study period, 2% of staphylococcal isolates within the hospital were mupirocin resistant. Thrice-weekly application of standardized antibacterial honey to hemodialysis catheter exit sites was safe, cheap, and effective and resulted in a comparable rate of catheter-associated infection to that obtained with mupirocin (although the study was not adequately powered to assess therapeutic equivalence). The effectiveness of honey against antibiotic-resistant microorganisms and its low likelihood of selecting for further resistant strains suggest that this agent may represent a satisfactory alternative means of chemoprophylaxis in patients with central venous catheters.

Abstract
Background Although several potential risk factors have been discussed, risk factors associated with bacterial colonization or even infection of catheters used for regional anaesthesia are not very well investigated. Methods In this prospective observational trial, 198 catheters at several anatomical sites where placed using a standardized technique. The site of insertion was then monitored daily for signs of infection (secretion at the insertion site, redness, swelling, or local pain). The catheters were removed when clinically indicated (no or moderate postoperative pain) or when signs of potential infection occurred. After sterile removal they were prospectively analyzed for colonization, defined as > 15 colony forming units. Results 33 (16.7%) of all catheters were colonized, and 18 (9.1%) of these with additional signs of local inflammation. Two of these patients required antibiotic treatment due to superficial infections. Stepwise logistic regression analysis was used to identify factors associated with catheter colonization. Out of 26 potential factors, three came out as statistically significant. Catheter placement in the groin (odds-ratio and 95%-confidence interval: 3.4; 1.5–7.8), and repeated changing of the catheter dressing (odds-ratio: 2.1; 1.4–3.3 per removal) increased the risk for colonization, whereas systemic antibiotics administered postoperatively decreased it (odds ratio: 0.41; 0.12–1.0). Conclusion Colonization of peripheral and epidural nerve catheter can only in part be predicted at the time of catheter insertion since two out of three relevant variables that significantly influence the risk can only be recorded postoperatively. Catheter localisation in the groin, removal of the dressing and omission of postoperative antibiotics were associated with, but were not necessarily causal for bacterial colonization. These factors might help to identify patients who are at increased risk for catheter colonization.

Catheter-related sepsis (CRS) is a common complication of long-term parenteral nutrition. Conventional antibiotic therapy is often effective in the short-term but, because of poor activity against intraluminal microbial biofilms, may not prevent relapse. Ethanol is an effective antiseptic. We describe a case of a patient with recurrent CRS successfully treated with 70% ethanol locks.

Abstract
BACKGROUND The purpose of this study is to compare a new temporary triple-lumen catheter (TLC) for dialysis that has a third lumen devoted to fluid and medication administration or blood sampling with a marketed dual-lumen catheter (DLC). METHODS Four hundred eighty-five patients referred for acute hemodialysis or apheresis were randomly assigned to either a TLC or DLC in a multicenter, prospective, randomized trial. RESULTS Analysis of blood flow rates was completed on 464 patients (228 patients, DLC; 236 patients, TLC) with a total of 1,681 hemodialysis (808 treatments, DLC; 873 treatments, TLC) and 82 apheresis treatments (37 treatments, DLC; 45 treatments, TLC). During hemodialysis, a median achieved flow rate (AFR) of 267 mL/min was realized for both groups (P = 0.58). During apheresis, a median AFR of 72.5 mL/min (range, 50 to 150 mL/min) was achieved in the DLC group, and 87 mL/min (range, 60 to 150 mL/min), in the TLC group (P = 0.14). Three hundred ninety-three patients (193 patients, DLC; 200 patients, TLC) had blood and catheter tip cultures performed on removal, and catheter-related bloodstream infection (CRBSI) status was determined. Thirty-one patients (7.9%) had a CRBSI: 16 patients (8.3%), DLC; and 15 patients (7.5%), TLC (P= 0.77). Incidence densities of CRBSI were 12.4/1,000 DLC-days and 10.2/1,000 TLC-days (P = 0.59). The CRBSI incidence of 18.2/1,000 catheter-days for femoral sites was significantly greater than the 7/1,000 catheter-days for jugular sites (P = 0.02) and 6.6/1,000 catheter-days for combined jugular and subclavian sites (P = 0.01). In multivariate analysis, antibiotic use was the only factor related to CRBSI (odds ratio, 0.30; 95% confidence interval, 0.12 to 0.76). There were no statistically significant differences in rates of other complications between the 2 catheters. CONCLUSION Results show that the new TLC is similar to the marketed DLC.

Abstract
OBJECTIVE The hub connecting the catheter and the infusion equipment is a common portal of entry for bacteria causing catheter-related sepsis. We assessed the efficacy of a new hub model (Segur-Lock) that incorporates an antiseptic chamber filled with 3% iodinated alcohol in preventing endoluminal catheter contamination and catheter-related bloodstream infection arising at the hub. DESIGN Prospective, randomized, multicenter study. SETTING Seven medical and surgical adult intensive care units in Spain. PATIENTS A total of 230 patients aged 18 yrs or older requiring the insertion of a nontunneled central venous catheter for >or=6 days from January 1, 1998, to April 30, 1999. INTERVENTIONS Patients were randomized at the time of catheter insertion to receive catheters with standard Luer-lock connector (control group, n = 114) or catheters with the new hub model (n = 116). MEASUREMENTS AND MAIN RESULTS Skin, catheter tip, and hub cultures were performed at the time the catheter was withdrawn because therapy was terminated or due to suspicion of sepsis, in which case peripheral blood and infusate cultures were simultaneously taken. Catheter-related bloodstream infection was diagnosed in 19 (8.3%) patients. Catheters were more often withdrawn because of suspicion of infection in the control group (43.8%) than in the new hub model group (30.1%, p <.035). The prevalence of culture-positive catheter hubs without associated bacteremia (colonization) was higher in the control group (14.4% vs. 4.3%, p <.001). Catheter-related bloodstream infection from the catheter hub also occurred more frequently in controls than in patients assigned to the new hub model (7% vs. 1.7%; p <.049; relative risk, 4.14; 95% confidence interval, 0.8-19). CONCLUSIONS This new antiseptic chamber-containing hub has proved to be effective in preventing endoluminal bacterial colonization and catheter-related bloodstream infection from hub contamination in intensive care unit patients with central venous catheters inserted for >or=6 days.

Abstract
The aim of this paper is to present an instrument that helps to create a subcutaneous path for central catheters used for hemodialysis, as well as a non traumatic internal introduction of Tesio's catheters and other systems (Dacron cap). We have designed a tunneling tool which consists of a solid but light weight hand set, connected to an extension that ends with an olive shape dilator to be connected to a trocar. Thus, precise tunneling is guaranteed through a non traumatic procedure, allowing exact anchorage of catheters.

Abstract
OBJECTIVE To determine whether fibrin-coated central venous catheters have a higher infection rate, and spawn more septic emboli, than uncoated catheters after exposure to bacteremia. DESIGN Animal study comparing catheter infection and blood cultures of fibrin-coated and uncoated catheters exposed to bacteremia. SETTING Animal laboratory. SUBJECTS Adult male Sprague-Dawley rats. INTERVENTIONS A total of 210 rats had catheters placed with the proximal end buried subcutaneously. Rats were divided into three groups: tail vein bacterial injection on day 0 (no fibrin group) or on day 10 (fibrin group), or no injection/saline injection (control, n = 40). Bacterial injections were 1 x 108 colony forming units of either Staphylococcus epidermidis (n = 100) or Enterobacter cloacae (n = 60). Animals were killed 3 days after injection. Blood cultures were obtained via cardiac puncture, and catheters were removed via the chest. Half of the catheter was rolled onto agar and the other half was placed in trypticase soy broth. Plates and broth were incubated at 37 degrees C for 48 hrs. The presence of >15 colonies on roll plates, or growth in broth, was accepted as a positive sign of infection. Microscopy was performed on day 20-10 catheters. Thirty animals without catheters had bacterial injections and underwent blood culture 3 days after injection. MEASUREMENTS AND MAIN RESULTS Catheter infection with S. epidermidis occurred in 32% of roll plates and 80% of broth from the fibrin group vs. 4% and 20% from the no fibrin group (p <.01 for each). Catheter infection with E. cloacae occurred in 50% of roll plates and 80% of broth from the fibrin group vs. 0% and 12% from the no fibrin group (p <.01 for each). Positive blood cultures occurred in 47 of 68 animals from the fibrin group vs. 8 of 68 from the no fibrin group (p <.01). Microscopy showed a fibrin sheath on 20 of 20 catheters. Without catheters, 30 of 30 blood cultures were negative. CONCLUSION The fibrin sheath significantly enhanced catheter-related infection and persistent bacteremia.

Abstract
Bloodstream infections (BSI) constitute a significant public health problem and represent an important cause of morbidity and mortality in hospitalized patients, with an approximate incidence of one episode per hundred hospital admissions. Studies on BSI in HIV+ patients have identified central venous catheters (CVC) as a risk factor, with an attributable mortality rate of 10-20%. The long-term CVC-related infection risk appeared to be 5 to 10-fold higher with respect to the infection rates among HIV- patients. CVC associated infection rate ranges from 1.3 to 12 infections per 1,000 catheter-days. Staphylococcus aureus is the most common etiologic agent causative of CVC-related BSI, likely the result of the high skin and nasal carriage of this organism among HIV+ patients, mostly intravenous drug users. Coagulase-negative staphylococci are also frequently identified as cause of CVC-related BSI, likely the result of breaches in infection control measures and in antiseptic technique during CVC management. Treating bacteremia without catheter removal would be optimal, but the reported efficacy of systemic antibiotic therapy alone is only 25-32%. Conversely, recent studies have shown that, using an antibiotic-lock procedure, up to 90% of HIV-infected and uninfected patients achieved complete eradication of catheter-related BSIs without catheter removal. Clinical trials using new materials such as covalently linked heparin on the CVC surface, electrically charged CVC, novel topical agents that interfere with bacterial colonization, antiadhesin molecules and agents that block the gene expression involved in the biofilm formation, are all needed to reduce the high catheter-related infection risk among HIV+ patients.

Abstract
The aim of this study was to identify risk factors for catheter-associated bloodstream infection (CABSI) in neonates. We undertook a prospective investigation of the potential risk factors for CABSI (patient-related, treatment-related and catheter-related) in a neonatal intensive care unit (NICU) using univariate and multivariate techniques. We also investigated the relationship between catheter hub and catheter exit site colonization with CABSI.Thirty-five episodes of CABSI occurred in 862 central catheters over a period of 8028 catheter-days, with a cumulative incidence of 4.1/100 catheters and an incidence density of 4.4/1000 catheter days. Factors independently associated with CABSI were: catheter hub colonization (odds ratio [OR] = 44.1, 95% confidence interval [CI] = 14.5 to 134.4), exit site colonization (OR = 14.4, CI = 4.8 to 42.6), extremely low weight (< 1000 g) at time of catheter insertion (OR = 5.13, CI = 2.1 to 12.5), duration of parenteral nutrition (OR=1.04, CI=1.0 to 1.08) and catheter insertion after first week of life (OR = 2.7, CI = 1.1 to 6.7). In 15 (43%) out of the 35 CABSI episodes the catheter hub was colonized, in nine (26%) cases the catheter exit site was colonized and in three (9%) cases colonization was found at both sites. This prospective cohort study on CABSI in a NICU identified five risk factors of which two can be used for risk-stratified incidence density description (birthweight and time of catheter insertion). It also emphasized the importance of catheter exit site, hub colonization and exposure to parenteral nutrition in the pathogenesis of CABSI.

Abstract
PURPOSE To review the mechanisms, diagnosis, treatment and prophylaxis of catheter-related sepsis in intensive care unit patients. DATA SOURCES A Medline research of the English- or French-language reports published between 1966 and 2000 and a manual research of references of relevant papers. STUDY SELECTION Experimental, clinical and basic research studies related to catheter-related sepsis. DATA EXTRACTION Data in selected articles were reviewed, and relevant clinical information was extracted. DATA SYNTHESIS Infection remains the major complication related to catheter insertion. No bacteriological exam or systematic catheter change is required in the absence of infection suspicion. In the intensive care unit, and without septic shock, the surveillance of skin cultures at the catheter insertion site or the time to positivity of hub-blood versus peripheral-blood culture determination may reduce the number of unnecessary removed catheters. Catheter change over a guidewire is not recommended because of the risk of dissemination of infection. When the catheter is removed, a quantitative culture is warranted. The treatment of catheter-related sepsis is based on catheter removal. The use of antibiotics is limited to some organisms or when the infection is complicated. The persistence of fever and positive blood cultures 72 h after catheter removal require to look for dissemination of infection or septic thrombophlebitis, especially if S. aureus or Candida are incriminated. The treatment of infection without catheter removal is not recommended in the intensive care unit because of a high risk of treatment failure. Compliance with catheter care guidelines and continuing quality improvement programs are the two major procedures in reducing catheter infection. CONCLUSIONS Improved understanding of the pathophysiology of catheter-related sepsis has led to improved prevention. Compliance with catheter care guidelines and continuing quality improvement programs are majors procedures to reduce the risk of catheter infection.

Abstract
The purpose of this review is to describe the most common complications of home total parenteral nutrition, their identification, treatment and prevention. Data sources were manuscripts and abstracts published in the English literature since 1968. Studies were selected for summarization in this review on the basis of clinical relevance to the practicing clinician. Home total parenteral nutrition is a relatively safe, life-saving method for nutrient delivery in patients with compromised gastrointestinal function. However, numerous complications, with associated morbidity and mortality, involving the delivery system and the gastrointestinal, renal, and skeletal systems may develop. Catheter-related complications are often preventable and treatable when they occur, although renal and bone abnormalities have elusive etiologies.

Abstract
In febrile neutropenic patients, prompt empiric antimicrobial intervention is mandatory. Numerous studies have demonstrated the benefit of broad-spectrum beta-lactams active against Gram-negative aerobes as well as against streptococci and Staphylococcus aureus in this setting. With this interventional strategy, a reduction of infection-related mortality to < or = 10% of patients undergoing intensive remission induction or consolidation chemotherapy could be obtained. Thereby, subgroups of patients have been identified who require an empiric modification of antimicrobial treatment, e.g., patients with catheter-related infections, with pulmonary infiltrates, or with unexplained fever (FUO) not responding to first-line antibacterials. In two consecutive, prospectively randomized trials conducted by the German Paul Ehrlich Society it could be shown that empiric antifungal therapy is beneficial for second-line treatment in patients with persistent FUO and improves first-line treatment results in patients with lung infiltrates. The addition of glycopeptides, however, should be restricted to patients with catheter-related infections due to coagulase-negative staphylococci or with infections due to multiresistant Gram-positive pathogens.

Abstract
Nasal surveillance cultures were performed for 54 patients exhibiting >/=10(3) CFU of methicillin-resistant coagulase-negative staphylococci per ml in central venous catheter (CVC) rinse cultures over a 6-month period. Forty-two of the nasal cultures yielded growth of methicillin-resistant coagulase-negative staphylococci, and 33 of the 42 cultures contained organisms that belonged to the same species as the CVC isolates. Of the 33 same-species isolates, 20 appeared to be identical strains by pulsed-field gel electrophoresis analysis. These data suggest that measures should be taken to reduce cross-contamination between the respiratory tract and intravascular devices. However, the potential interest in detecting methicillin-resistant coagulase-negative staphylococcus carriage in high-risk patients is hampered by the lack of sensitivity of nasal surveillance cultures.

Abstract
PURPOSE Tunneled hemodialysis catheter dysfunction often occurs from fibrin sheath formation. As a way to preserve existing catheter venous access sites, the authors evaluated over-the-wire exchange of catheters through pre-existing subcutaneous tunnels as an alternative to catheter removal and de novo catheter replacement. PATIENTS AND METHODS One hundred nineteen catheters were placed in 68 patients. Seventy-seven catheters were placed de novo and 42 catheters were placed through the pre-existing subcutaneous tunnels of failing catheters. Technical success, short-term complications, infection rates, and functional catheter longevity were evaluated. RESULTS Technical success for catheter exchange was 93%. Infection rates were comparable to those of de novo catheter placement: 0.15 and 0.11 infections per 100 catheter days for de novo and exchanged catheters, respectively. Catheter duration of function was not significantly different for de novo versus exchanged catheters: 63% and 51% at 3 months, 51% and 37% at 6 months, and 35% and 30% at 12 months, respectively. CONCLUSIONS Over-the-wire exchange of tunneled hemodialysis catheters is safe and easily performed. It causes no increase in infectious complications and provides similar catheter longevity to de novo catheter placement. The procedure is an important option for prolonging tunneled hemodialysis catheter access sites.

Abstract
BACKGROUND The aim of this study was to determine the rate of infectious complications following axillary vein cannulation and to compare to that observed after internal jugular vein catheterization. METHODS A prospective comparative open study was carried out to determine the rate of infectious complications related to the use of catheters inserted via the axillary vein or the internal jugular vein. During the study period all patients submitted to central venous catheterization were evaluated. A total of 141 patients entered and completed the study. Catheter insertion sites were either the axillary vein punctured in the axilla, or the internal jugular vein punctured using an anterior approach. Catheter tips were cultured using a quantitative technique. Clinical information pertaining to the analysis was prospectively collected. RESULTS A total of 141 catheters from 141 patients entered was studied. Clinical characteristics and risk factors for catheter infection were similar in both groups. The incidence of catheter-related infection (including catheter-related sepsis, and bacteremia) was not different between the two groups (axillary vein: 8.1%; internal jugular vein: 7.6%). Catheter-related bacteremia were seen at a rate of 3.7% in the internal jugular vein group and a rate of 1.6% in the axillary vein group (NS). The incidence of catheter colonization was similar in both groups (axillary vein: 14.5%; internal jugular vein: 11.4%). CONCLUSION Catheter-related infection after axillary vein catheterization was similar to that observed after internal jugular vein catheterization. The chance of developing catheter-related sepsis was less than 10% with either route when catheters were used for the treatment of severely ill patients.
