Predictors of CRBSI involving long-term catheters include the following: a >3:1 quantity of Candida growing from the catheter-drawn blood cultures, compared with percutaneous blood cultures; catheter-drawn blood cultures growing >2 h before percutaneous blood cultures [36, 48, 49, 198]; candidemia in a patient who has not received chemotherapy or steroid therapy within 1 month before the onset of infection and who has no dissemination or other apparent source for the bloodstream infection except the intravascular catheter; candidemia in a patient receiving hyperalimentation through the catheter; and persistent candidemia unresponsive to systemic antifungal therapy [199, 200]. If a blood sample for culture cannot be drawn from a peripheral vein, it is recommended that 2 blood samples should be obtained through different catheter lumens (B-III). Determine how often a -lactam antibiotic is used instead of vancomycin for -lactam-susceptible staphylococcal CRBSI among patients without a -lactam allergy. V. What are the unique aspects of treating infections associated with long-term CVCs or implanted catheter-related infections other than those related to hemodialysis catheters? Coagulase-negative staphylococci are the most common cause of catheter-related infection. Patients with hemodialysis-associated CRBSI due to gram-negative pathogens or CRBSI due to coagulase-negative staphylococci may have the catheter retained and be treated with adjunctive antibiotic lock therapy for 3 weeks, or they may have the catheter exchanged over a guidewire and then receive the same antibiotic course (figure 4). 10.1016/j.idc.2018.06.002 Abstract Despite recent gains, intravascular catheter-related bloodstream infection (CRBSI) remains an important clinical problem resulting in significant morbidity, mortality, and excess economic cost. has clinical research contracts with MedImmune and Tibotec. An overview of the treatment and prevention of tunneled hemodialysis CRBSI and exit-site infections is presented in this topic review. 16. Failure or delay in removing the catheter increases the risk for hematogenous complications [144]. In evaluating the evidence regarding the management of intravascular catheter-related infections, the Expert Panel followed a process used in the development of other IDSA guidelines. Bacteria that are most often implicated in contamination of infusate include gram-negative bacilli capable of reproducing at room temperature, such as Klebsiella species, Enterobacter species, Serratia species, Burkholdaria cepacia, Ralstonia pickettii, and Citrobacter freundii [4]. Recent studies suggest that the risk of arterial CRBSI approaches that associated with short-term CVCs [63-65]. The aim of these guidelines is to provide updated recommendations for the diagnosis and management of CRBSI in adults. Infective endocarditis cannot be ruled out by negative transthoracic echocardiograph findings alone (B-II). Urokinase and other thrombolytic agents are not recommended as adjunctive therapy for patients with CRBSI (B-I). Conventional amphotericin B therapy is also effective but is associated with more adverse effects. Confirmation by multiple percutaneous blood culture results positive for the same organism is required before meaningful conclusions can be drawn as to the significance of the culture results. 55. The accuracy of all diagnostic microbiologic methods greatly increases with increasing pretest probability. Antibiotic lock therapy should be used for catheter salvage (B-II); however, if antibiotic lock therapy cannot be used in this situation, systemic antibiotics should be administered through the colonized catheter (C-III). 68. Members of the Expert Panel were provided with the IDSA's conflict of interest disclosure statement and were asked to identify ties to companies developing products that might be affected by promulgation of the guideline. PCR to target bacterial 16S ribosomal DNA is sensitive and specific for diagnosing catheter-related infection but is not routinely used in clinical microbiology laboratories [51]. An open-label clinical trial among solid-organ transplant recipients reported a 63% success rate in treating vancomycin-resistant enterococci bloodstream infections with linezolid [168]. The following organizations endorsed the guidelines: American Society of Nephrology, European Society of Clinical Microbiology and Infectious Diseases, Pediatric Infectious Diseases Society, Society for Critical Care Medicine, and the Society for Healthcare Epidemiology of America. 16. Catheter-Related Bloodstream Infection (CRBSI) Intravenous administration of thrombolytic agents, such as urokinase, should not be used as adjunctive treatment for CRBSI [58, 59]. Data Availability Statement Go to: Abstract Introduction Catheter-related bloodstream infection (CRBSI) and catheter colonization (CC) are two complications among haemodialysis (HD) patients that lead to increased morbidity and mortality. If a pulmonary artery catheter is removed because of suspected infection, the highest yield is to culture the introducer, rather than the catheter itself [21]. The guideline was reviewed and approved by the IDSA Standards and Practice Guidelines Committee and the Board of Directors prior to dissemination. Evidence summary. The Expert Panel met face-to-face on 1 occasion and via teleconference on 8 occasions to complete the work of the guideline. Clinical Practice Guidelines for the Diagnosis and Management of - IDSA The Infectious Diseases Society of America. As a consequence Table 1 Categories of evidence levels used in this guideline Category, grade Definition Strength of recommendation A Strongly supports a recommendation for use 107. Approach to the treatment of a patient with a long-term central venous catheter (CVC) or a port (P)-related bloodstream infection. Antifungal therapy should be initiated when yeast is isolated from a blood culture or when the suspicion of fungemia is high [90, 96-98]. Patients receiving dialysis who have CRBSI due to vancomycin-resistant enterococci can be treated with either daptomycin (6 mg/kg after each dialysis session) or oral linezolid (600 mg every 12 h) (B-II). Catheter-Related Bloodstream Infections and Catheter Colonization among Attributes of good guidelines include validity, reliability, reproducibility, clinical applicability, clinical flexibility, clarity, multidisciplinary process, review of evidence, and documentation [2]. Prior guidelines call for negative TEE findings for all patients with S. aureus CRBSI to allow for a treatment duration of only 2 weeks [1]. 62. Isolation of these microorganisms from a single blood culture set does not prove true bloodstream infection. Hospitalization is only indicated for patients with severe sepsis or metastatic infection. Blood culture contamination issues, peripheral blood samples, and paired peripheral and catheter-drawn blood samples. Consensus development on the basis of evidence. 33. Skin preparation with either alcohol, alcoholic chlorhexidine (>0.5%), or tincture of iodine (10%) leads to lower blood culture contamination rates than does the use of povidone-iodine [39, 40]. During the past 2 decades, rates of gram-negative bacillary intravascular device infection and secondary bacteremia among adults have decreased, supplanted by infections due to coagulase-negative staphylococci, S. aureus (often MRSA), and Candida species [172]. When studied among patients with cancer and patients hospitalized in intensive care units who had both long-term and short-term catheters, this method has been shown to have accuracy comparable to that of quantitative blood cultures, as well as greater cost-effectiveness [35, 47-49]. If a TEE is performed, it should be done at least 57 days after onset of bacteremia to minimize the possibility of false-negative results (B-II). The optimal duration of therapy has not been established for treating catheter-related infection in children with or without catheter removal [89, 90]. 23. Feedback from external peer reviewers was obtained. Specific management strategies for infective endocarditis due to CRBSI are summarized in figures 2and 3, and general guidelines can be found elsewhere [272]. Contamination in the hospital pharmacy should be suspected if an increase in bloodstream infection due to the same microorganism occurs among patients on different hospital units. Consider culture of samples obtained from the insertion site and catheter hubs, if available, as noted above (A-II). 99. 57. However, signs and symptoms of endocarditis, persistent bacteremia, or enterococcal bacteremia in the presence of a prosthetic valve warrant further evaluation with TEE [160, 161]. For central venous catheters (CVCs), the catheter tip should be cultured, rather than the subcutaneous segment (B-III). 110. D.E.C. Short-term catheters should be removed from patients with CRBSI due to gram-negative bacilli, S. aureus, enterococci, fungi, and mycobacteria (A-II). Catheter cultures should be done when a catheter is removed because of suspected CRBSI; catheter cultures should not be obtained routinely (A-II).

Practical approach to the management of catheter-related - PubMed For surgically implanted catheters and peripherally inserted CVCs, they are coagulase-negative staphylococci, enteric gram-negative bacilli, S. aureus, and P. aeruginosa [8]. Antibiotic dosing for patients who are undergoing hemodialysis. Growth of >15 cfu/plate of the same microbe from the insertion site swab sample and hub swab sample cultures and from a peripheral blood culture suggests CRBSI [33]. Overall, quantitative blood cultures are the most accurate method by which to diagnose CRBSI [34, 35]. Future studies are needed to more fully clarify the epidemiology, ideal definition, molecular pathogenesis, and optimal clinical approach to this newly . Patients who receive empirical vancomycin and who are found to have CRBSI due to methicillin-susceptible S. aureus should be switched to cefazolin (A-II). In the largest published comparative trial of CRBSI treatment involving antimicrobial therapy and catheter removal, 149 (88%) of 169 patients had a successful microbiologic outcome when evaluated 12 weeks after the end of treatment, and there was an 83% microbiologic success rate among 98 cases of CRBSI due to S. aureus [52].

If a venous access subcutaneous port is removed because of suspected CRBSI, send the port to the microbiology laboratory for qualitative culture of the port reservoir contents, in addition to the catheter tip (B-II). 77. 25. Transthoracic echocardiograph findings are insufficient to rule out infective endocarditis (A-II). In addition, there is increasing concern over the evolution of MDR gram-negative bacilli having carbapenemases that confer resistance to carbapenems, and many of these enzymes are active against cephalosporins [173]. Staphylococci are the main etiologic agents, followed by Enterococcus and Candida species [24, 25]. It is frequently not feasible to obtain a peripheral blood sample for culture from patients who are receiving dialysis [99]. If necessary, the entire Expert Panel will be reconvened to discuss potential changes. Surveillance blood cultures should be obtained 1 week after completion of an antibiotic course for CRBSI if the catheter has been retained (B-III). II. 18. 56. When appropriate, the Expert Panel will recommend revision of the guideline to the Standards and Practice Guidelines Committee and the IDSA Board for review and approval. Nevertheless, if a catheter is to be removed for suspected catheter-related infection and the patient is at high risk for mechanical complications during catheter reinsertion, a guidewire exchange of the catheter can decrease the risk of mechanical complications [71]. Should blood cultures be routinely obtained after completing a course of antibiotics for CRBSI? Leonard A.

CFU, colony-forming units. Quantitative blood cultures and/or DTP should be done before initiation of antimicrobial therapy and with the same volume of blood per bottle (A-II). Clinical identifiers can be helpful in determining which patients with S. aureus bacteremia have a complicated infection [143, 144, 146].
