Abstract
BACKGROUND Peripherally inserted central catheters (PICCs) facilitate diagnostic and therapeutic interventions in health care. PICCs can fail due to infective and non-infective complications, which PICC materials and design may contribute to, leading to negative sequelae for patients and healthcare systems. OBJECTIVES To assess the effectiveness of PICC material and design in reducing catheter failure and complications. SEARCH METHODS The University of Queensland and Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, and CINAHL databases and the WHO ICTRP and ClinicalTrials.gov trials registers to 16 May 2023. We aimed to identify other potentially eligible trials or ancillary publications by searching the reference lists of retrieved included trials, as well as relevant systematic reviews, meta-analyses, and health technology assessment reports. We contacted experts in the field to ascertain additional relevant information. SELECTION CRITERIA We included randomised controlled trials (RCTs) evaluating PICC design and materials. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. Our primary outcomes were venous thromboembolism (VTE), PICC-associated bloodstream infection (BSI), occlusion, and all-cause mortality. Secondary outcomes were catheter failure, PICC-related BSI, catheter breakage, PICC dwell time, and safety endpoints. We assessed the certainty of evidence using GRADE. MAIN RESULTS We included 12 RCTs involving approximately 2913 participants (one multi-arm study). All studies except one had a high risk of bias in one or more risk of bias domain. Integrated valve technology compared to no valve technology for peripherally inserted central catheter design Integrated valve technology may make little or no difference to VTE risk when compared with PICCs with no valve (risk ratio (RR) 0.71, 95% confidence interval (CI) 0.19 to 2.63; I² = 0%; 3 studies; 437 participants; low certainty evidence). We are uncertain whether integrated valve technology reduces PICC-associated BSI risk, as the certainty of the evidence is very low (RR 0.20, 95% CI 0.01 to 4.00; I² = not applicable; 2 studies (no events in 1 study); 257 participants). Integrated valve technology may make little or no difference to occlusion risk when compared with PICCs with no valve (RR 0.86, 95% CI 0.53 to 1.38; I² = 0%; 5 studies; 900 participants; low certainty evidence). We are uncertain whether use of integrated valve technology reduces all-cause mortality risk, as the certainty of evidence is very low (RR 0.85, 95% CI 0.44 to 1.64; I² = 0%; 2 studies; 473 participants). Integrated valve technology may make little or no difference to catheter failure risk when compared with PICCs with no valve (RR 0.80, 95% CI 0.62 to 1.03; I² = 0%; 4 studies; 720 participants; low certainty evidence). We are uncertain whether integrated-valve technology reduces PICC-related BSI risk (RR 0.51, 95% CI 0.19 to 1.32; I² = not applicable; 2 studies (no events in 1 study); 542 participants) or catheter breakage, as the certainty of evidence is very low (RR 1.05, 95% CI 0.22 to 5.06; I² = 20%; 4 studies; 799 participants). Anti-thrombogenic surface modification compared to no anti-thrombogenic surface modification for peripherally inserted central catheter design We are uncertain whether use of anti-thrombogenic surface modified catheters reduces risk of VTE (RR 0.67, 95% CI 0.13 to 3.54; I² = 15%; 2 studies; 257 participants) or PICC-associated BSI, as the certainty of evidence is very low (RR 0.20, 95% CI 0.01 to 4.00; I² = not applicable; 2 studies (no events in 1 study); 257 participants). We are uncertain whether use of anti-thrombogenic surface modified catheters reduces occlusion (RR 0.69, 95% CI 0.04 to 11.22; I² = 70%; 2 studies; 257 participants) or all-cause mortality risk, as the certainty of evidence is very low (RR 0.49, 95% CI 0.05 to 5.26; I² = not applicable; 1 study; 111 participants). Use of anti-thrombogenic surface modified catheters may make little or no difference to risk of catheter failure (RR 0.76, 95% CI 0.37 to 1.54; I² = 46%; 2 studies; 257 participants; low certainty evidence). No PICC-related BSIs were reported in one study (111 participants). As such, we are uncertain whether use of anti-thrombogenic surface modified catheters reduces PICC-related BSI risk (RR not estimable; I² = not applicable; very low certainty evidence). We are uncertain whether use of anti-thrombogenic surface modified catheters reduces the risk of catheter breakage, as the certainty of evidence is very low (RR 0.15, 95% CI 0.01 to 2.79; I² = not applicable; 2 studies (no events in 1 study); 257 participants). Antimicrobial impregnation compared to non-antimicrobial impregnation for peripherally inserted central catheter design We are uncertain whether use of antimicrobial-impregnated catheters reduces VTE risk (RR 0.54, 95% CI 0.05 to 5.88; I² = not applicable; 1 study; 167 participants) or PICC-associated BSI risk, as the certainty of evidence is very low (RR 2.17, 95% CI 0.20 to 23.53; I² = not applicable; 1 study; 167 participants). Antimicrobial-impregnated catheters probably make little or no difference to occlusion risk (RR 1.00, 95% CI 0.57 to 1.74; I² = 0%; 2 studies; 1025 participants; moderate certainty evidence) or all-cause mortality (RR 1.12, 95% CI 0.71 to 1.75; I² = 0%; 2 studies; 1082 participants; moderate certainty evidence). Antimicrobial-impregnated catheters may make little or no difference to risk of catheter failure (RR 1.04, 95% CI 0.82 to 1.30; I² = not applicable; 1 study; 221 participants; low certainty evidence). Antimicrobial-impregnated catheters probably make little or no difference to PICC-related BSI risk (RR 1.05, 95% CI 0.71 to 1.55; I² = not applicable; 2 studies (no events in 1 study); 1082 participants; moderate certainty evidence). Antimicrobial-impregnated catheters may make little or no difference to risk of catheter breakage (RR 0.86, 95% CI 0.19 to 3.83; I² = not applicable; 1 study; 804 participants; low certainty evidence). AUTHORS' CONCLUSIONS There is limited high-quality RCT evidence available to inform clinician decision-making for PICC materials and design. Limitations of the current evidence include small sample sizes, infrequent events, and risk of bias. There may be little to no difference in the risk of VTE, PICC-associated BSI, occlusion, or mortality across PICC materials and designs. Further rigorous RCTs are needed to reduce uncertainty.

The antimicrobial effectiveness of chlorhexidine and chlorhexidine-silver sulfadiazine-impregnated central venous catheters against the emerging fungal pathogen Candida auris. Am J Infect Control 2024:S0196-6553(24)00576-5. [PMID: 38944155 DOI: 10.1016/j.ajic.2024.06.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2024] [Revised: 06/20/2024] [Accepted: 06/20/2024] [Indexed: 07/01/2024]
Abstract
BACKGROUND Candida auris is an emerging multidrug-resistant fungus associated with catheter-related bloodstream infections. In vitro efficacy of chlorhexidine (CHX) and CHX-silver sulfadiazine-impregnated (CHX-S) antimicrobial central venous catheters (CVCs) against C auris was investigated. METHODS Minimum inhibitory and bactericidal CHX concentrations were determined against 19 C auris isolates. To assess extraluminal efficacy, segments from CVCs impregnated externally (CHX-S1) and both externally and internally (CHX-S2) were plasma-conditioned for 1- and 6-day, and to assess intraluminal efficacy, CHX-S2 CVCs were preconditioned with saline-lock for 6days, followed by 24-hour C auris inoculation and microbial adherence determination on impregnated and nonimpregnated CVCs. RESULTS CHX inhibited all C auris isolates with minimum inhibitory and bactericidal concentrations range of 8 to 128 μg/mL. C auris adherence was reduced on CHX-S1 and CHX-S2 extraluminally by 100% on day 1, 86.96% to 100% on day 7, and intraluminally on CHX-S2 by 56.86% to 90.52% on day 7. DISCUSSION CHX and CHX-S CVC performance against C auris observed in this study is consistent with antimicrobial benefits observed in prior preclinical and randomized controlled clinical studies. CONCLUSIONS CHX showed strong inhibitory and cidal effects on C auris. CHX-S CVCs proved highly efficacious against this pathogen under in vitro conditions. Additional studies, however, are required to confirm clinical benefit.

Am J Infect Control 2023; 51:1425-1429. [PMID: 37088441 DOI: 10.1016/j.ajic.2023.04.163] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Revised: 04/12/2023] [Accepted: 04/13/2023] [Indexed: 04/25/2023]
Abstract
BACKGROUND Several studies have investigated the safety and efficacy of antimicrobial peripherally inserted central catheters (PICCs), and the results are conflicting. Therefore, in this systematic review and meta-analysis, we aimed to summarize and identify the effect of antimicrobial PICCs on central line-associated bloodstream infection (CLABSI) risk. METHODS A systematic search of PubMed, Ovid MEDLINE, Ovid Embase, and Web of Science was performed to identify relevant studies up to December 2022. RESULTS A total of 9 studies were included for analysis. There were 7 retrospective/prospective cohort studies and 2 randomized controlled trials. The 9 studies involved 51,373 patients with PICCs. Among these patients, 6,563 (12.8%) antimicrobial-coated/impregnated PICCs and 44,810 (87.2%) nonantimicrobial-impregnated PICCs were inserted. The meta-analysis showed that antimicrobial PICCs had a nonsignificant association with lower CLABSI risk compared with noncoated PICCs (relative risk [RR] = 0.67; 95% CI, 0.43-1.05). In the subgroup analysis, minocycline-rifampin-(RR = 0.30; 95% CI, 0.19-0.49) or chlorhexidine-coated (RR = 0.61; 95% CI, 0.04-8.55) PICCs showed an association with reduced risk of CLABSI. In the adult population, antimicrobial PICCs had a nonsignificant association with lower CLABSI risk (RR = 0.50; 95% CI, 0.20-1.22). CONCLUSIONS This systematic review and meta-analysis suggested that antimicrobial PICCs had a nonsignificant association with lower CLABSI risk compared with noncoated PICCs. Minocycline-rifampin-or chlorhexidine-coated PICCs showed an association with reduced risk of CLABSI.

Abstract
PURPOSE Central venous catheters (CVCs) and pulmonary artery catheters (PACs) containing chlorhexidine, silver sulfadiazine, or latex can cause perioperative anaphylaxis. We examined the incidence of and outcomes associated with anaphylaxis caused by CVCs/PACs. METHODS In a historical cohort study, we retrospectively identified adult patients fitted with CVCs/PACs at the Mayo Clinics in Minnesota, Arizona, and Florida from 1 January 2008 to 1 March 2018. Potential and confirmed cases of perioperative anaphylactic reactions were individually reviewed and classified. RESULTS During the study period, 39,505 procedures were performed during which CVCs/PACs were inserted. Of these, 2,937 patients with pre-existing chlorhexidine, sulfonamide (sulfa), and/or latex allergies had CVCs/PACs inserted that contained these substances. Perioperative anaphylaxis, in which CVCs/PACs were the confirmed or potential causative agent, occurred during 53 procedures. Seven patients had a preoperatively reported sulfa or latex allergy; no patients had a preoperative chlorhexidine allergy. Six of the seven patients with reported allergies to sulfa or latex had a CVC/PAC inserted that contained these substances. Twenty-four patients with anaphylaxis had postoperative allergic disease consultation; ten of these (42%) underwent skin testing. CONCLUSION Perioperative anaphylactic reactions related to CVCs/PACs containing chlorhexidine, silver sulfadiazine, or latex were rare in this large historical cohort study. We identified 2,937 patients with pre-existing chlorhexidine, sulfa, and/or latex allergies and had CVCs/PACs inserted that contained these substances. Although few cases of perioperative anaphylaxis attributable to these substances were observed in patients with corresponding allergies, the potential for substantial complication exists. Providers should be aware of the potential for these hidden exposures.

Abstract
Antibiotic prophylaxis in interventional radiology (IR) is widely used; however, such practice is based on data from the surgical literature. Although published guidelines can help determine the need for prophylactic antibiotic use in the patient undergoing percutaneous procedures, local practice patterns often dictate when such medications are given. In this article, the current state of periprocedural antibiotic use in commonly performed IR procedures (i.e., tube and catheter placements) is presented.

Abstract
Acinetobacter baumannii (A. baumannii) is a leading cause of nosocomial infections as this pathogen has certain attributes that facilitate the subversion of natural defenses of the human body. A. baumannii acquires antibiotic resistance determinants easily and can thrive on both biotic and abiotic surfaces. Different resistance mechanisms or determinants, both transmissible and non-transmissible, have aided in this victory over antibiotics. In addition, the propensity to form biofilms (communities of organism attached to a surface) allows the organism to persist in hospitals on various medical surfaces (cardiac valves, artificial joints, catheters, endotracheal tubes, and ventilators) and also evade antibiotics simply by shielding the bacteria and increasing its ability to acquire foreign genetic material through lateral gene transfer. The biofilm formation rate in A. baumannii is higher than in other species. Recent research has shown how A. baumannii biofilm-forming capacity exerts its effect on resistance phenotypes, development of resistome, and dissemination of resistance genes within biofilms by conjugation or transformation, thereby making biofilm a hotspot for genetic exchange. Various genes control the formation of A. baumannii biofilms and a beneficial relationship between biofilm formation and "antimicrobial resistance" (AMR) exists in the organism. This review discusses these various attributes of the organism that act independently or synergistically to cause hospital infections. Evolution of AMR in A. baumannii, resistance mechanisms including both transmissible (hydrolyzing enzymes) and non-transmissible (efflux pumps and chromosomal mutations) are presented. Intrinsic factors [biofilm-associated protein, outer membrane protein A, chaperon-usher pilus, iron uptake mechanism, poly-β-(1, 6)-N-acetyl glucosamine, BfmS/BfmR two-component system, PER-1, quorum sensing] involved in biofilm production, extrinsic factors (surface property, growth temperature, growth medium) associated with the process, the impact of biofilms on high antimicrobial tolerance and regulation of the process, gene transfer within the biofilm, are elaborated. The infections associated with colonization of A. baumannii on medical devices are discussed. Each important device-related infection is dealt with and both adult and pediatric studies are separately mentioned. Furthermore, the strategies of preventing A. baumannii biofilms with antibiotic combinations, quorum sensing quenchers, natural products, efflux pump inhibitors, antimicrobial peptides, nanoparticles, and phage therapy are enumerated.

The potential for developing new antimicrobial resistance from the use of medical devices containing chlorhexidine, minocycline, rifampicin and their combinations: a systematic review.

[PMID: 34222960 PMCID: PMC8210168 DOI: 10.1093/jacamr/dlaa002] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2019] [Revised: 12/04/2019] [Accepted: 12/15/2019] [Indexed: 12/13/2022] Open
Abstract
Background Catheter infections remain one of the most persistent adverse events causing significant morbidity, economic impact and mortality. Several strategies have been proposed to reduce these infections including the use of catheters embedded with antibiotics and/or antiseptics. One reoccurring challenge is the fear that antimicrobial medical devices will induce resistance. The aim of this systematic review is to evaluate the evidence for induced antimicrobial resistance caused by exposure to antimicrobial medical devices. Methods Four electronic databases [MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Scopus] were screened for studies published between 1983 and 2019 regarding assessment of microbial resistance with use of medical devices containing chlorhexidine, minocycline, rifampicin or combinations thereof. Development of new resistance, selection for tolerant organisms and 'no change in resistance' were assessed. Results Forty-four publications, grouped by study type and stratified by drug assessed, were included for analyses. The majority of studies found no change in resistance after exposure to antimicrobial medical devices (13 in vitro, 2 in vivo, 20 clinical). Development of new resistance was commonly reported with the use of rifampicin as a single agent and only reported in one study assessing the minocycline/rifampicin combination (M/R); however, the increase in MIC was well below clinical relevance. Conclusions Emergence of new resistance to combinations of M/R, minocycline/rifampicin/chlorhexidine (M/R/CH) and chlorhexidine/silver sulfadiazine (CHXSS) was rare. No clinical trials confirmed its occurrence and some refuted it. The risk of development of new resistance to these antimicrobial combinations appears more fear-based than substantiated by clinical and experimental evidence but warrants continued surveillance.

Abstract
Background and Purpose Short-term central venous catheterization (CVC) is one of the commonly used invasive interventions in ICU and other patient-care areas. Practice and management of CVC is not standardized, varies widely, and need appropriate guidance. Purpose of this document is to provide a comprehensive, evidence-based and up-to-date, one document source for practice and management of central venous catheterization. These recommendations are intended to be used by critical care physicians and allied professionals involved in care of patients with central venous lines. Methods This position statement for central venous catheterization is framed by expert committee members under the aegis of Indian Society of Critical Care Medicine (ISCCM). Experts group exchanged and reviewed the relevant literature. During the final meeting of the experts held at the ISCCM Head Office, a consensus on all the topics was made and the recommendations for final document draft were prepared. The final document was reviewed and accepted by all expert committee members and after a process of peer-review this document is finally accepted as an official ISCCM position paper. Modified grade system was utilized to classify the quality of evidence and the strength of recommendations. The draft document thus formulated was reviewed by all committee members; further comments and suggestions were incorporated after discussion, and a final document was prepared. Results This document makes recommendations about various aspects of resource preparation, infection control, prevention of mechanical complication and surveillance related to short-term central venous catheterization. This document also provides four appendices for ready reference and use at institutional level. Conclusion In this document, committee is able to make 54 different recommendations for various aspects of care, out of which 40 are strong and 14 weak recommendations. Among all of them, 42 recommendations are backed by any level of evidence, however due to paucity of data on 12 clinical questions, a consensus was reached by working committee and practice recommendations given on these topics are based on vast clinical experience of the members of this committee, which makes a useful practice point. Committee recognizes the fact that in event of new emerging evidences this document will require update, and that shall be provided in due time.

Abstract
Fracture-related infection (FRI) remains a challenging complication that imposes a heavy burden on orthopaedic trauma patients. The surgical management eradicates the local infectious focus and if necessary facilitates bone healing. Treatment success is associated with debridement of all dead and poorly vascularized tissue. However, debridement is often associated with the formation of a dead space, which provides an ideal environment for bacteria and is a potential site for recurrent infection. Dead space management is therefore of critical importance. For this reason, the use of locally delivered antimicrobials has gained attention not only for local antimicrobial activity but also for dead space management. Local antimicrobial therapy has been widely studied in periprosthetic joint infection, without addressing the specific problems of FRI. Furthermore, the literature presents a wide array of methods and guidelines with respect to the use of local antimicrobials. The present review describes the scientific evidence related to dead space management with a focus on the currently available local antimicrobial strategies in the management of FRI. LEVEL OF EVIDENCE:: Therapeutic Level V. See Instructions for Authors for a complete description of levels of evidence.

Abstract
Healthcare-associated infections (HAIs) are a major cause of concern because of the high levels of associated morbidity, mortality, and cost. In addition, children and intensive care unit (ICU) patients are more vulnerable to these infections due to low levels of immunity. Various medical interventions and statistical process control techniques have been suggested to counter the spread of these infections and aid early detection of an infection outbreak. Methods such as hand hygiene help in the prevention of HAIs and are well-documented in the literature. This chapter demonstrates the utilization of a systems methodology to model and validate factors that contribute to the risk of HAIs in a pediatric ICU. It proposes an approach that has three unique aspects: it studies the problem of HAIs as a whole by focusing on several HAIs instead of a single type, it projects the effects of interventions onto the general patient population using the system-level model, and it studies both medical and behavioral interventions and compares their effectiveness. This methodology uses a systems modeling framework that includes simulation, risk analysis, and statistical techniques for studying interventions to reduce the transmission likelihood of HAIs.

Validity of surrogate endpoints assessing central venous catheter-related infection: evidence from individual- and study-level analyses. Clin Microbiol Infect 2019; 26:563-571. [PMID: 31586658 DOI: 10.1016/j.cmi.2019.09.022] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2019] [Revised: 09/17/2019] [Accepted: 09/20/2019] [Indexed: 12/12/2022]
Abstract
OBJECTIVES The prevention of catheter-related bloodstream infection (CRBSI) has been an area of intense research, but the heterogeneity of endpoints used to define catheter infection makes the interpretation of randomized controlled trials (RCTs) problematic. The aim of this study was to determine the validity of different endpoints for central venous catheter infections. DATA SOURCES (a) Individual-catheter data were collected from 9428 catheters from four large RCTs; (b) study-level data from 70 RCTs were identified with a systematic search. Eligible studies were RCTs published between January 1987 and October 2018 investigating various interventions to reduce infections from short-term central venous catheters or short-term dialysis catheters. For each RCT the prevalence rates of CRBSI, quantitative catheter tip colonization, catheter-associated infection (CAI) and central line-associated bloodstream infection (CLABSI) were extracted for each randomized study arm. METHODS CRBSI was used as the gold-standard endpoint, for which colonization, CAI and CLABSI were evaluated as surrogate endpoints. Surrogate validity was assessed as (1) the individual partial coefficient of determination (individual-pR2) using individual catheter data; (2) the coefficient of determination (study-R2) from mixed-effect models regressing the therapeutic effect size of the surrogates on the effect size of CRBSI, using study-level data. RESULTS Colonization showed poor agreement with CRBSI at the individual-patient level (pR2 = 0.33 95% CI 0.28-0.38) and poor capture at the study level (R2 = 0.42, 95% CI 0.21-0.58). CAI showed good agreement with CRBSI at the individual-patient level (pR2 = 0.80, 95% CI 0.76-0.83) and moderate capture at the study level (R2 = 0.71, 95% CI 0.51-0.85). CLABSI showed poor agreement with CRBSI at the individual patient level (pR2 = 0.34, 95% CI 0.23-0.46) and poor capture at the study level (R2 = 0.28, 95% CI 0.07-0.76). CONCLUSIONS CAI is a moderate to good surrogate endpoint for CRBSI. Colonization and CLABSI do not reliably reflect treatment effects on CRBSI and are consequently more suitable for surveillance than for clinical effectiveness research.

Polymeric Composites with Silver (I) Cyanoximates Inhibit Biofilm Formation of Gram-Positive and Gram-Negative Bacteria. Polymers (Basel) 2019; 11:polym11061018.

Abstract
Biofilms are surface-associated microbial communities known for their increased resistance to antimicrobials and host factors. This resistance introduces a critical clinical challenge, particularly in cases associated with implants increasing the predisposition for bacterial infections. Preventing such infections requires the development of novel antimicrobials or compounds that enhance bactericidal effect of currently available antibiotics. We have synthesized and characterized twelve novel silver(I) cyanoximates designated as Ag(ACO), Ag(BCO), Ag(CCO), Ag(ECO), Ag(PiCO), Ag(PICO) (yellow and red polymorphs), Ag(BIHCO), Ag(BIMCO), Ag(BOCO), Ag(BTCO), Ag(MCO) and Ag(PiPCO). The compounds exhibit a remarkable resistance to high intensity visible light, UV radiation and heat and have poor solubility in water. All these compounds can be well incorporated into the light-curable acrylate polymeric composites that are currently used as dental fillers or adhesives of indwelling medical devices. A range of dry weight % from 0.5 to 5.0 of the compounds was tested in this study. To study the potential of these compounds in preventing planktonic and biofilm growth of bacteria, we selected two human pathogens (Gram-negative Pseudomonas aeruginosa and Gram-positive Staphylococcus aureus) and Gram-positive environmental isolate Bacillus aryabhattai. Both planktonic and biofilm growth was abolished completely in the presence of 0.5% to 5% of the compounds. The most efficient inhibition was shown by Ag(PiCO), Ag(BIHCO) and Ag(BTCO). The inhibition of biofilm growth by Ag(PiCO)-yellow was confirmed by scanning electron microscopy (SEM). Application of Ag(BTCO) and Ag(PiCO)-red in combination with tobramycin, the antibiotic commonly used to treat P. aeruginosa infections, showed a significant synergistic effect. Finally, the inhibitory effect lasted for at least 120 h in P. aeruginosa and 36 h in S. aureus and B. aryabhattai. Overall, several silver(I) cyanoximates complexes efficiently prevent biofilm development of both Gram-negative and Gram-positive bacteria and present a particularly significant potential for applications against P. aeruginosa infections.

Abstract
We report a case series of anaphylaxis to chlorhexidine-coated central venous catheters (CVCs) when used in cardiac surgical patients in our institution. Our experience, together with increasing reports of anaphylaxis to chlorhexidine-coated CVCs from other sources indicates that chlorhexidine-coated CVCs are not without additional risk. Attempts to lower rates of catheter-related bloodstream infection has led to the widespread adoption of chlorhexidine-coated CVCs in the perioperative and critical care setting, including for routine cardiac surgery. However, closer scrutiny indicates that there is lack of strong evidence demonstrating a meaningful reduction in rates of sepsis or serious morbidity, especially with CVC dwell times of less than seven days. Given the lack of clear benefit, we recommend non-coated CVCs for routine cardiac surgery, with even consideration for chlorhexidine-coated CVCs when specifically indicated for patients at high risk of CVC infection.

Abstract
OBJECTIVES To quantify the current bacteriology of deep surgical site infections (SSIs) after fracture surgery at 1 institution and to compare those data with historical controls at the same institution, assessing variations in infecting organisms over the past decade. DESIGN Retrospective review. SETTING Level I trauma center. PATIENTS/PARTICIPANTS Two hundred forty-three patients requiring surgical intervention for deep SSI between January 2011 and December 2015 were compared with 211 patients requiring surgical intervention for deep SSI between December 2006 and December 2010. INTERVENTION None. MAIN OUTCOME MEASUREMENTS Bacteria were categorized as Staphylococcus aureus, coagulase-negative staphylococci (CoNS), Streptococcus, Enterococcus, gram-negative rods (GNR), gram-positive rods, anaerobes, or negative cultures. The proportion of each bacterial type was determined and compared with previously published data from the same trauma center (December 2006 to December 2010). RESULTS Patients most commonly had S. aureus infections (48%), followed by GNR (40%) and CoNS (19%). The proportion of CoNS species (26% vs. 12%, P < 0.01) in infected patients was significantly higher during the current study period compared with historical controls. The proportion of S. aureus species in infected patients was significantly less during the current study period (39% vs. 56%, P < 0.01). The reduction in the proportion of S. aureus species in infected patients was driven by a decrease in the proportion of methicillin-resistant S. aureus (MRSA) in the overall sample. CONCLUSIONS Bacteriology of deep SSI of fractures has changed substantially over the past decade at our center, specifically the proportions of GNR, CoNS, and MRSA. LEVEL OF EVIDENCE Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Abstract
Treatment of medical device-related infections is challenging and recurrence is common. The main reason for this is that microorganisms adhere to the surfaces of medical devices and enter into a biofilm state in which they display distinct growth rates, structural features, and protection from antimicrobial agents and host immune mechanisms compared with their planktonic counterparts. This article reviews how microorganisms form biofilms and the mechanisms of protection against antimicrobial agents and the host immune system provided by biofilms. Also discussed are innovative strategies for the diagnosis of biofilm-associated infection and novel approaches to treatment and prevention of medical device-associated infections.

Abstract
Background Coated polyglactin 910 suture with chlorhexidine (NEOSORB® Plus) has recently been developed to imbue the parent suture with antibacterial activity against organisms that commonly cause surgical site infections (SSI). This prospective, single-blinded, randomized trial, was performed to compare the intraoperative handling and wound healing characteristics of NEOSORB® Plus with those of the traditional polyglactin 910 suture (NEOSORB®) in urologic surgery patients. Methods Patients (aged 19 to 80 years, n = 100) were randomized in a 1:1 ratio for treatment with either NEOSORB® Plus or NEOSORB®, and stratified into an open surgery or a minimally invasive surgery group. The primary endpoint was the assessment of overall intraoperative handling of the sutures. Secondary endpoints included specific intraoperative handling measures and wound healing characteristics. Wound healing was assessed at one and 11 days after surgery. Cumulative skin infection, seroma, and suture sinus events within 30 days after surgery were also evaluated. Results A total of 96 patients were included, with 47 patients in the NEOSORB® Plus group and 49 patients in the NEOSORB® group. Scores for intraoperative handling were favorable and were not significantly different between the two suture groups. Wound healing characteristics were also comparable. The incidence of adverse events was 13.6%, although none were deemed attributable to the suture, and no difference was observed between the two groups. Conclusions NEOSORB® Plus is not inferior to traditional sutures in terms of intraoperative handling and wound healing, potentially making NEOSORB® Plus a beneficial alternative for patients at increased risk of SSI. Trial registration ClinicalTrials.gov: NCT02431039. Trial registration date 14 August 2015.

Effectiveness of antimicrobial-coated central venous catheters for preventing catheter-related blood-stream infections with the implementation of bundles: a systematic review and network meta-analysis. Ann Intensive Care 2018; 8:71. [PMID: 29904809 PMCID: PMC6002334 DOI: 10.1186/s13613-018-0416-4] [Citation(s) in RCA: 33] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2018] [Accepted: 06/01/2018] [Indexed: 11/29/2022] Open
Abstract
Background Catheter-related blood-stream infections (CRBSIs) are the most common complication when using central venous catheters (CVCs). Whether coating CVCs under bundles could further reduce the incidence of CRBSIs is unclear. We aimed to assess the effectiveness of implementing the use of bundles with antimicrobial-coated CVCs for preventing catheter-related blood-stream infections. Methods In this systematic review and network meta-analyses, we searched the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library in addition to the EMBASE, MEDLINE, CINAHL, and Web of Science databases for studies published before July 2017. The primary outcome was the rate of CRBSIs per 1000 catheter-days, and the secondary outcome was the incidence of catheter colonization. Results Twenty-three studies revealed significant differences in the rate of CRBSIs per 1000 catheter-days between antimicrobial-impregnated and standard CVCs (RR 0.70, 95% CI 0.53–0.91, p = 0.008). Thirty-three trials were included containing 10,464 patients who received one of four types of CVCs. Compared with a standard catheter, chlorhexidine/silver sulfadiazine- and antibiotic-coated catheters were associated with lower numbers of CRBSIs per 1000 catheter-days (ORs and 95% CrIs: 0.64 (0.40–0.955) and 0.53 (0.25–0.95), respectively) and a lower incidence of catheter colonization (ORs and 95% CrIs: 0.44 (0.34–0.56) and 0.30 (0.20–0.46), respectively). Conclusions Outcomes are superior for catheters impregnated with chlorhexidine/silver sulfadiazine or other antibiotics than for standard catheters in preventing CRBSIs and catheter colonization under bundles. Compared with silver ion-impregnated CVCs, chlorhexidine/silver sulfadiazine antiseptic catheters resulted in fewer cases of microbial colonization of the catheter but did not reduce CRBSIs.

Abstract
PURPOSE OF REVIEW Chlorhexidine gluconate (CHG) and mupirocin are increasingly used for Staphylococcus aureus decolonization to prevent healthcare-associated infections; however, increased use of these agents has led to concerns for growing resistance and reduced efficacy. In this review, we describe current understanding of reduced susceptibility to CHG and mupirocin in S. aureus and their potential clinical implications. RECENT FINDINGS While emergence of S. aureus tolerant or resistant to topical antimicrobial agents used for decolonization is well described, the clinical impact of reduced susceptibility is not clear. Important challenges are that standardized methods of resistance testing and interpretation are not established, and the risk for selection for co- or cross-resistance using universal, as opposed to targeted decolonization, is unclear. Evidence continues to support S. aureus decolonization in certain patient groups, although further studies are needed to determine the long-term impact of CHG and mupirocin resistance on efficacy. Strategies to mitigate further development of reduced susceptibility and the consequences of selection pressures through universal decolonization on resistance will benefit from further investigation.

Abstract
Vascular catheters are a major cause of nosocomial bloodstream infections. ChloraLock (ATTWILL Medical Solutions, Inc, West Jordan, UT, and ICU Medical, Inc, San Clemente, CA) is a novel antimicrobial device containing chlorhexidine digluconate (CHG) that is fitted onto a syringe and infuses CHG into the catheter lumen during locking. The objective of this study was to evaluate the antimicrobial efficacy of ChloraLock with in vitro tests and its ability to reduce Staphylococcus aureus contamination of catheters in the external jugular veins of Yorkshire swine. ChloraLock significantly reduced the bacterial load in the in vitro tests by up to 6 log10 colony-forming units (CFU) and by 3 to 4 log10 CFU/lumen in vivo in a swine model with 0.9% NaCl catheter locks.

Abstract
Device-related infections (DRIs) are a significant cause of morbidity and mortality among older adults. Indwelling devices (urinary catheters, percutaneous feeding tubes, and central venous catheters) are frequently used in this vulnerable population. Indwelling devices provide a portal of entry for pathogenic organisms to invade a susceptible host and cause infection and are an important target for infection prevention and antimicrobial stewardship efforts. Within the "Chain of Infection" that leads to DRIs in older adults, multiple opportunities exist to implement interventions that "break the links" and reduce colonization with multidrug-resistant organisms, reduce infections, and improve antimicrobial use.

Abstract
Purpose: This study compared an antimicrobial and anti-thrombogenic peripherally inserted central catheter treated with a chlorhexidine-based technology, a peripherally inserted central catheter with bulk distributed fluoro-oligomers, and a poly 2-methoxyethyl acrylate–based peripherally inserted central catheter to an untreated peripherally inserted central catheter (control) in an ovine model at 14 and 30 days post-implant. Methods: One of four types of peripherally inserted central catheters was surgically implanted into the left jugular vein of each of 18 sheep for 14 or 30 days. Blood analysis consisted of complete blood counts, serum chemistries, and coagulation (fibrinogen, prothrombin time, and partial thromboplastin time) profiles. Sheep were sacrificed to examine the vein and thorax. Histological analysis was performed on serial catheter sections using standard microscopy on hematoxylin and eosin–stained tissues. Results: All catheters developed fibroblastic sleeves at both 14 and 30 days. The chlorhexidine-peripherally inserted central catheter showed a 64% lower mean fibroblastic sleeve weight and a 66% shorter mean fibroblastic sleeve length compared to the untreated control at 14 days. By 30 days, compared to untreated control, the chlorhexidine-peripherally inserted central catheter showed 81% lower mean fibroblastic sleeve weight with 75% shorter mean fibroblastic sleeve length, the fluoro-oligomer-peripherally inserted central catheter showed 54% lower mean sheath weight with 40% shorter mean fibroblastic sleeve length, and the poly 2-methoxyethyl acrylate-peripherally inserted central catheter had 41% lower mean fibroblastic sleeve weight with 57% lower fibroblastic sleeve length. Conclusion: Among the three anti-thrombogenic peripherally inserted central catheter technologies, the chlorhexidine-peripherally inserted central catheter had the smallest fibroblastic sleeves, followed by the fluoro-oligomer-peripherally inserted central catheter, poly 2-methoxyethyl acrylate-peripherally inserted central catheter, and control peripherally inserted central catheter.

Abstract
Obtaining central venous access is one of the most commonly performed procedures in hospital settings. Multiple devices such as peripherally inserted central venous catheters, tunneled central venous catheters (eg, Hohn catheter, Hickman catheter, C. R. Bard, Inc, Salt Lake City UT), and implantable ports are available for this purpose. The device selected for central venous access depends on the clinical indication, duration of the treatment, and associated comorbidities. It is important for health care providers to familiarize themselves with the types of central venous catheters available, including information about their indications, contraindications, and potential complications, especially the management of catheters in the setting of catheter-related bloodstream infections. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Abstract
Central line-associated bloodstream infection (CLABSI) and catheter-associated urinary tract infection (CAUTI) are costly and morbid. Despite evidence-based guidelines, Some intensive care units (ICUs) continue to have elevated infection rates. In October 2015, we performed a systematic search of the peer-reviewed literature within the PubMed and Cochrane databases for interventions to reduce CLABSI and/or CAUTI in adult ICUs and synthesized findings using a narrative review process. The interventions were categorized using a conceptual model, with stages applicable to both CAUTI and CLABSI prevention: (stage 0) avoid catheter if possible, (stage 1) ensure aseptic placement, (stage 2) maintain awareness and proper care of catheters in place, and (stage 3) promptly remove unnecessary catheters. We also looked for effective components that the 5 most successful (by reduction in infection rates) studies of each infection shared. Interventions that addressed multiple stages within the conceptual model were common in these successful studies. Assuring compliance with infection prevention efforts via auditing and timely feedback were also common. Hospitalists with patient safety interests may find this review informative for formulating quality improvement interventions to reduce these infections.

Abstract
Background The efficacy of antimicrobial central venous catheters (CVCs) remains questionable. In this network meta-analysis, we aimed to assess the comparative efficacy of antimicrobial CVC impregnations in reducing catheter-related infections in adults. Methods We searched 4 electronic databases (Medline, the Cochrane Central Register of Controlled Trials, Embase, CINAHL) and internet sources for randomized controlled trials, ongoing clinical trials, and unpublished studies up to August 2016. Studies that assessed CVCs with antimicrobial impregnation with nonimpregnated catheters or catheters with another impregnation were included. Primary outcomes were clinically diagnosed sepsis, catheter-related bloodstream infection (CRBSI), and all-cause mortality. We performed a network meta-analysis to estimate risk ratio (RR) with 95% confidence interval (CI). Results Sixty studies with 17255 catheters were included. The effects of 14 impregnations were investigated. Both CRBSI and catheter colonization were the most commonly evaluated outcomes. Silver-impregnated CVCs significantly reduced clinically diagnosed sepsis compared with silver-impregnated cuffs (RR, 0.54 [95% CI, .29-.99]). When compared to no impregnation, significant CRBSI reduction was associated with minocycline-rifampicin (RR, 0.29 [95% CI, .16-.52]) and silver (RR, 0.57 [95% CI, .38-.86]) impregnations. No impregnations significantly reduced all-cause mortality. For catheter colonization, significant decreases were shown by miconazole-rifampicin (RR, 0.14 [95% CI, .05-.36]), 5-fluorouracil (RR, 0.34 [95% CI, .14-.82]), and chlorhexidine-silver sulfadiazine (RR, 0.60 [95% CI, .50-.72]) impregnations compared with no impregnation. None of the studies evaluated antibiotic/antiseptic resistance as the outcome. Conclusions Current evidence suggests that the minocycline-rifampicin-impregnated CVC appears to be the most effective in preventing CRBSI. However, its overall benefits in reducing clinical sepsis and mortality remain uncertain. Surveillance for antibiotic resistance attributed to the routine use of antimicrobial-impregnated CVCs should be emphasized in future trials.

Abstract
Device-associated infections are responsible for about half of nosocomial infections and can cause major medical and economical sequelae. Despite adherence to basic infection control measures, which constitute the mainstay for preventing infection, infections associated with certain devices continue to exist at unacceptably high rates. Potentially-preventive, antimicrobial-utilizing strategies include systemic antibiotic prophylaxis and local administration of antimicrobial agents (antibiotics or antiseptics), which includes antimicrobial irrigation of the surgical field, placement of antimicrobial carriers, antiseptic cleansing of the skin, dipping of surgical implants in antimicrobial solutions, and inserting antimicrobial-coated implants. Since bacterial colonization of the indwelling device is a prelude to infection, prevention of device colonization may lead to a lower rate of clinical infection. Different approaches for antimicrobial coating of devices have been variably successful in preventing device-associated infections. Optimal characteristics of antimicrobial coating can help predict the likelihood and degree of clinical protection against infection. This review addresses the impact of device-related infection, antimicrobial-utilizing approaches for preventing infection, clinical protection afforded by different types of antimicrobial coating, characteristics that predict the ability of antimicrobial coating of devices to prevent clinical infection, and future directions of antimicrobial coating.

Abstract
INTRODUCTION Catheter use is associated with many complications and is an iatrogenic source of morbidity and mortality in intensive care units (ICU). The catheter being studied (Certofix Protect) was developed to reduce the risk of catheter related infections. This clinical trial will compare the safety and efficiency of Certofix Protect with that of an ordinary Certofix catheter. METHODS AND ANALYSIS In this multicentre trial, we will randomly assigned dual lumen central venous catheterisation (≥5 ds) in patients in the adult ICU to the antimicrobial central venous catheter (CVC) group or the ordinary CVC group. We plan to recruit 12-16 medical centres in China. Our main objective is to assess the effectiveness of antimicrobial CVCs in reducing catheter related bloodstream infection (CRBSI), all cause mortality, catheter colonisation, catheter related thrombosis and other catheter related complications. The primary outcome is the incidence of CRBSI. ETHICS AND DISSEMINATION The ethics committee of West China Hospital of Sichuan University has granted ethics approval for this study (27 January 2015). The results will be published in peer reviewed journals and presented at conferences. TRIAL REGISTRATION NUMBER NCT02645682.

Abstract
Objective: to evaluate the effectiveness and safety in the use of second-generation central
venous catheters impregnated in clorhexidine and silver sulfadiazine when compared
with other catheters, being them impregnated or not, in order to prevent the
bloodstream infection prevention. Method: systematic review with meta-analysis. Databases searched: MEDLINE, EMBASE,
CINAHL, LILACS/SciELO, Cochrane CENTRAL; search in Congress Proceedings and
records from Clinical Trials. Results: 1.235 studies were identified, 97 were pre-selected and 4 were included. In
catheter-related bloodstream infection, there was no statistical significance
between second-generation impregnated catheter compared with the non-impregnated
ones, absolute relative risk 1,5% confidence interval 95% (3%-1%), relative risk
0,68 (confidence interval 95%, 0,40-1,15) and number needed to treat 66. In the
sensitivity analysis, there was less bloodstream infection in impregnated
catheters (relative risk 0,50, confidence interval 95%, 0,26-0,96). Lower
colonization, absolute relative risk 9,6% (confidence interval 95%, 10% to 4%),
relative risk 0,51 (confidence interval 95% from 0,38-0,85) and number needed to
treat 5. Conclusion: the use of second-generation catheters was effective in reducing the catheter
colonization and infection when a sensitivity analysis is performed. Future
clinical trials are suggested to evaluate sepsis rates, mortality and adverse
effects.

Abstract
Vancomycin-resistant Enterococcus faecium strains (VREfm) are critical public health concerns because they are among the leading causes of hospital-acquired bloodstream infections. Chlorhexidine (CHX) is a bisbiguanide cationic antiseptic that is routinely used for patient bathing and other infection control practices. VREfm are likely frequently exposed to CHX; however, the long-term effects of CHX exposure have not been studied in enterococci. In this study, we serially exposed VREfm to increasing concentrations of CHX for a period of 21 days in two independent experimental evolution trials. Reduced CHX susceptibility emerged (4-fold shift in CHX MIC). Subpopulations with reduced daptomycin (DAP) susceptibility were detected, which were further analyzed by genome sequencing and lipidomic analysis. Across the trials, we identified adaptive changes in genes with predicted or experimentally confirmed roles in chlorhexidine susceptibility (efrE), global nutritional stress response (relA), nucleotide metabolism (cmk), phosphate acquisition (phoU), and glycolipid biosynthesis (bgsB), among others. Moreover, significant alterations in membrane phospholipids were identified for some populations with reduced DAP susceptibility. Our results are clinically significant because they identify a link between serial subinhibitory CHX exposure and reduced DAP susceptibility. In addition, the CHX-induced genetic and lipidomic changes described in this study offer new insights into the mechanisms underlying the emergence of antibiotic resistance in VREfm.

Abstract
In this study, failure mode and effect analysis (FMEA), a proactive tool, was applied to reduce errors associated with the process which begins with assessment of patient and ends with treatment of complications. The aim of this study is to assess whether FMEA implementation will significantly reduce the incidence of catheter-related bloodstream infections (CRBSIs) in intensive care unit.The FMEA team was constructed. A team of 15 medical staff from different departments were recruited and trained. Their main responsibility was to analyze and score all possible processes of central venous catheterization failures. Failure modes with risk priority number (RPN) ≥100 (top 10 RPN scores) were deemed as high-priority-risks, meaning that they needed immediate corrective action. After modifications were put, the resulting RPN was compared with the previous one. A centralized nursing care system was designed.A total of 25 failure modes were identified. High-priority risks were "Unqualified medical device sterilization" (RPN, 337), "leukopenia, very low immunity" (RPN, 222), and "Poor hand hygiene Basic diseases" (RPN, 160). The corrective measures that we took allowed a decrease in the RPNs, especially for the high-priority risks. The maximum reduction was approximately 80%, as observed for the failure mode "Not creating the maximal barrier for patient." The averaged incidence of CRBSIs was reduced from 5.19% to 1.45%, with 3 months of 0 infection rate.The FMEA can effectively reduce incidence of CRBSIs, improve the security of central venous catheterization technology, decrease overall medical expenses, and improve nursing quality.

Abstract
Background Whenever the rate of central line-associated bloodstream infections (CLABSIs) remains high even after the implementation of preventive strategies, the use of chlorhexidine/silver sulfadiazine (CSS) or minocycline/rifampin (MR)-impregnated central venous catheters (CVCs) is currently recommended. Nevertheless, the efficacy of such CVCs against Candida albicans and other emerging non-albicans spp. has been insufficiently studied. This study aims to compare the activity of CSS and MR-impregnated CVCs against the yeasts most frequently isolated from CLABSIs. Methods For biofilm formation assays, type strains and clinical isolates of C. albicans, C. glabrata and C. parapsilosis sensu stricto were used. Segments of standard polyurethane, MR and second-generation CSS-CVCs were tested. The biofilm metabolic activity was measured by a semi-quantitative XTT reduction assay. Results CSS catheter segments significantly reduced the biofilm metabolic activity by all tested Candida spp., with inhibition ranging from 60% to 100%. The MR catheter segments promoted C. albicans and C. parapsilosis biofilm formation and exhibited an inconspicuous effect against C. glabrata. Conclusions Among the recommended antimicrobial CVCs, CSS-CVCs proved to be superior in the inhibition of biofilm formation by the most frequent yeasts causing CLABSIs. Data from this in vitro study may suggest that patients at high risk for invasive candidosis could benefit from the use of CSS-CVCs.

Abstract
Bacterial skin infections represent some of the most common infectious diseases globally. Prevention and treatment of skin infections can involve application of a topical antimicrobial, which may be an antibiotic (such as mupirocin or fusidic acid) or an antiseptic (such as chlorhexidine or alcohol). However, there is limited evidence to support the widespread prophylactic or therapeutic use of topical agents. Challenges involved in the use of topical antimicrobials include increasing rates of bacterial resistance, local hypersensitivity reactions (particularly to older agents, such as bacitracin), and concerns about the indiscriminate use of antiseptics potentially coselecting for antibiotic resistance. We review the evidence for the major clinical uses of topical antibiotics and antiseptics. In addition, we review the mechanisms of action of common topical agents and define the clinical and molecular epidemiology of antimicrobial resistance in these agents. Moreover, we review the potential use of newer and emerging agents, such as retapamulin and ebselen, and discuss the role of antiseptic agents in preventing bacterial skin infections. A comprehensive understanding of the clinical efficacy and drivers of resistance to topical agents will inform the optimal use of these agents to preserve their activity in the future.

Abstract
Over the past decades the use of medical devices, such as catheters, artificial heart valves, prosthetic joints, and other implants, has grown significantly. Despite continuous improvements in device design, surgical procedures, and wound care, biomaterial-associated infections (BAI) are still a major problem in modern medicine. Conventional antibiotic treatment often fails due to the low levels of antibiotic at the site of infection. The presence of biofilms on the biomaterial and/or the multidrug-resistant phenotype of the bacteria further impair the efficacy of antibiotic treatment. Removal of the biomaterial is then the last option to control the infection. Clearly, there is a pressing need for alternative strategies to prevent and treat BAI. Synthetic antimicrobial peptides (AMPs) are considered promising candidates as they are active against a broad spectrum of (antibiotic-resistant) planktonic bacteria and biofilms. Moreover, bacteria are less likely to develop resistance to these rapidly-acting peptides. In this review we highlight the four main strategies, three of which applying AMPs, in biomedical device manufacturing to prevent BAI. The first involves modification of the physicochemical characteristics of the surface of implants. Immobilization of AMPs on surfaces of medical devices with a variety of chemical techniques is essential in the second strategy. The main disadvantage of these two strategies relates to the limited antibacterial effect in the tissue surrounding the implant. This limitation is addressed by the third strategy that releases AMPs from a coating in a controlled fashion. Lastly, AMPs can be integrated in the design and manufacturing of additively manufactured/3D-printed implants, owing to the physicochemical characteristics of the implant material and the versatile manufacturing technologies compatible with antimicrobials incorporation. These novel technologies utilizing AMPs will contribute to development of novel and safe antimicrobial medical devices, reducing complications and associated costs of device infection.

Abstract
BACKGROUND Selection of central venous catheter insertion site in ICU patients could help reduce catheter-related infections. Although subclavian was considered the most appropriate site, its preferential use in ICU patients is not generalized and questioned by contradicted meta-analysis results. In addition, conflicting data exist on alternative site selection whenever subclavian is contraindicated. OBJECTIVE To compare catheter-related bloodstream infection and colonization risk between the three sites (subclavian, internal jugular, and femoral) in adult ICU patients. DATA SOURCE We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled trials, CINAHL, and ClinicalTrials.gov. STUDY SELECTION Eligible studies were randomized controlled trials and observational ones. DATA EXTRACTION Extracted data were analyzed by pairwise and network meta-analysis. DATA SYNTHESIS Twenty studies were included; 11 were observational, seven were randomized controlled trials for other outcomes, and two were randomized controlled trials for sites. We evaluated 18,554 central venous catheters: 9,331 from observational studies, 5,482 from randomized controlled trials for other outcomes, and 3,741 from randomized controlled trials for sites. Colonization risk was higher for internal jugular (relative risk, 2.25 [95% CI, 1.84-2.75]; I = 0%) and femoral (relative risk, 2.92 [95% CI, 2.11-4.04]; I = 24%), compared with subclavian. Catheter-related bloodstream infection risk was comparable for internal jugular and subclavian, higher for femoral than subclavian (relative risk, 2.44 [95% CI, 1.25-4.75]; I = 61%), and lower for internal jugular than femoral (relative risk, 0.55 [95% CI, 0.34-0.89]; I = 61%). When observational studies that did not control for baseline characteristics were excluded, catheter-related bloodstream infection risk was comparable between the sites. CONCLUSIONS In ICU patients, internal jugular and subclavian may, similarly, decrease catheter-related bloodstream infection risk, when compared with femoral. Subclavian could be suggested as the most appropriate site, whenever colonization risk is considered and not, otherwise, contraindicated. Current evidence on catheter-related bloodstream infection femoral risk, compared with the other sites, is inconclusive.

Abstract
Vascular catheters are critical tools in modern healthcare yet present substantial risks of serious bloodstream infections that exact significant health and economic burdens. Drug-eluting antimicrobial vascular catheters have become important tools in preventing catheter-related bloodstream infections and their importance is expected to increase as significant initiatives are expanded to eliminate and make the occurrence of these infections unacceptable. Here we review clinically significant and emerging drug-eluting antimicrobial catheters within the categories of antibiotic, antiseptic, novel bioactive agents and energy-enhanced drug eluting antimicrobial catheters. Important representatives of each category are reviewed from the standpoints of mechanisms of action, physical-chemical properties, safety, in vitro and clinical effectiveness.

Abstract
Health care-associated infections (HAIs) are the primary cause of preventable death and disability among hospitalized patients. According to the Centers for Disease Control and Prevention (CDC), complications or infections secondary to either device implantation or surgery are referred to as HAIs. Specifically, the CDC monitors surgical site infections, central-line-associated bloodstream infection, catheter-associated urinary tract infections, and ventilator-associated pneumonias. This article explores HAIs specific to pathophysiology, epidemiology, and prevention, and how nurses can work together with other health care providers to decrease the incidence of these preventable complications.

Abstract
Central venous catheters are commonly used in critically ill patients. Such catheterization may entail mechanical and infectious complications. The interest in catheter-related infection lies in the morbidity, mortality and costs that it involved. Numerous contributions have been made in the prevention of catheter-related infection and the current review focuses on the possible current role of antimicrobial impregnated catheters to reduce catheter-related bloodstream infections (CRBSI). There is evidence that the use of chlorhexidine-silver sulfadiazine (CHSS), rifampicin-minocycline, or rifampicin-miconazol impregnated catheters reduce the incidence of CRBSI and costs. In addition, there are some clinical circumstances associated with higher risk of CRBSI, such as the venous catheter access and the presence of tracheostomy. Current guidelines for the prevention of CRBSI recommended the use of a CHSS or rifampicin-minocycline impregnated catheter in patients whose catheter is expected to remain in place > 5 d and if the CRBSI rate has not decreased after implementation of a comprehensive strategy to reduce it.

Abstract
After the publication in 2011 of latest guidelines of the Centers for Disease Control and Prevention (CDC) for the prevention of catheter-related bloodstream infections (CRBSI) some interesting findings have been published in that field. There has been published that skin disinfection with chlorhexidine alcohol reduced the risk of CRBSI compared to skin disinfection with povidone iodine alcohol, that the implementation of quality improvement interventions reduced the incidence of CRBSI, that the use of chlorhexidine impregnated dressing compared to standard dressings reduced the risk of CRBSI and catheter related cost in an health economic model, and that the use of antimicrobial/antiseptic impregnated catheters reduced the incidence of CRBSI and catheter related cost in clinical studies.

Abstract
Implant-associated infections (IAIs) are a dreaded complication mainly caused by biofilm-forming staphylococci. Implant surfaces preventing microbial colonization would be desirable. We examined the preventive effect of a silver-coated titanium-aluminum-niobium (TiAlNb) alloy. The surface elicited a strong, inoculum-dependent activity againstStaphylococcus epidermidisandStaphylococcus aureusin an agar inhibition assay. Gamma sterilization and alcohol disinfection did not alter the effect. In a tissue cage mouse model, silver coating of TiAlNb cages prevented perioperative infections in an inoculum-dependent manner and led to a 100% prevention rate after challenge with 2 × 10(6)CFU ofS. epidermidisper cage. InS. aureusinfections, silver coating had only limited effect. Similarly, daptomycin or vancomycin prophylaxis alone did not preventS. aureusinfections. However, silver coating combined with daptomycin or vancomycin prophylaxis thwarted methicillin-resistantS. aureusinfections at a prevention rate of 100% or 33%, respectively. Moreover, silver release from the surface was independent of infection and occurred rapidly after implantation. On day 2, a peak of 82 μg Ag/ml was reached in the cage fluid, corresponding to almost 6× the MIC of the staphylococci. Cytotoxicity toward leukocytes in the cage was low and temporary. Surrounding tissue did not reveal histological signs of silver toxicity.In vitro, no emergence of silver resistance was observed in several clinical strains of staphylococci upon serial subinhibitory silver exposures. In conclusion, our data demonstrate that silver-coated TiAlNb is potent for prevention of IAIs and thus can be considered for clinical application.

Abstract
Orthopaedic and trauma device-related infection (ODRI) remains one of the major complications in modern trauma and orthopaedic surgery.Despite best practice in medical and surgical management, neither prophylaxis nor treatment of ODRI is effective in all cases, leading to infections that negatively impact clinical outcome and significantly increase healthcare expenditure.The following review summarises the microbiological profile of modern ODRI, the impact antibiotic resistance has on treatment outcomes, and some of the principles and weaknesses of the current systemic and local antibiotic delivery strategies.The emerging novel strategies aimed at preventing or treating ODRI will be reviewed. Particular attention will be paid to the potential for clinical impact in the coming decades, when such interventions are likely to be critically important.The review focuses on this problem from an interdisciplinary perspective, including basic science innovations and best practice in infectious disease.
