Abstract
BACKGROUND Patients with inflammatory bowel disease (IBD) occasionally require central venous catheter (CVC) placement to support a therapeutic plan. Given that CVC can predispose patients to infection, this investigation was undertaken to assess the incidence, risk factors, and outcomes of CVC-related blood stream infection (CRBSI) in patients with IBD during routine clinical practice. METHODS Data were compiled using retrospective chart reviews of 1367 patients treated at our IBD center between 2007 and 2012 during routine clinical practice. Among the 1367 patients, 314 who had received CVC placements were included. Patients with positive blood culture were considered as "definite" CRBSI, whereas "possible" CRBSI was defined as patients in whom fever alleviated within 48 hours post-CVC without any other infection. Patients' demographic variables including age, body mass index, serum albumin, duration of CVC placement, use of antibiotics, medications for IBD, and perioperative status between CRBSI and non-CRBSI subgroups were compared by applying a multivariate Poisson logistic regression model. RESULTS Among the 314 patients with CVC placement, there were 83 CRBSI cases (26.4%). The average time to the onset of CRBSI was 22.5 days (range 4-105 days). The jugular vein access was found to be the most serious risk of CRBSI (risk ratio 2.041 versus subclavian vein). All patients with CRBSI fully recovered. CONCLUSIONS In this investigation, regardless of the patients' demographic features including immunosuppressive therapy, up to 30% of febrile IBD patients with CVC showed CRBSI. It is believed that CVC placement per se is a risk of CRBSI in patients with IBD.

Abstract
BACKGROUND Central venous catheters are devices used for therapeutic, diagnostic, and monitoring purposes. Complications associated with central venous catheter use include those related to their insertion, rupture and displacement of the catheter, occlusion, thrombosis, and infection. Of these the latter is important due to the high morbidity and mortality it causes in the patients, and total parenteral nutrition increases the risk. The aim of this study is determine the incidence and risk factors associated with catheter-related infection in patients on parenteral nutrition. MATERIAL AND METHODS A retrospective, observational, and cross-sectional study was conducted, by analysing patients on total parenteral nutrition who developed a catheter-related infection in a 6-month period. Multiple variables were studied, looking for significance. A statistically significant relationship was considered with a p<0.05. RESULTS The study consisted of 85 patients, of whom 52% were women and 48% men. The median age was 54 years. The most frequent diagnosis was enterocutaneous fistula. Catheter associated infection was present in 19% of patients. The most frequent microorganisms found were Staphyloccocus sp. (44%) and Candida sp. (25%). Median time between central venous catheter insertion and infection was 78±64 days. There was a significance between days with a central venous catheters and infection development (p=0.014). Infection developed in 81% of patients on whom surgery was performed (p<0.05) CONCLUSION: It was found that patients with a longer use of a central venous catheter (p=0.014) and those who were operated on in conjunction with total parenteral nutrition (p<0.05) were more prone to develop a catheter-associated infection.

In situ diagnostic methods for catheter related bloodstream infection in burns patients: A pilot study. Burns 2016; 42:434-40. [PMID: 26778703 DOI: 10.1016/j.burns.2015.07.004] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2015] [Revised: 06/20/2015] [Accepted: 07/09/2015] [Indexed: 11/24/2022]
Abstract
BACKGROUND One of the most common and potentially fatal complications in critically ill burns patients is catheter related bloodstream infection (CR-BSI). Lack of in situ diagnostic techniques requires device removal if CR-BSI is suspected with 75-85% of catheters withdrawn unnecessarily. AIMS To assess the sensitivity, specificity and accuracy of two in situ diagnostic methods for CR-BSI in an adult ICU burns population: Differential Time to Positivity (DTP) and Semi-Quantitative Superficial Cultures (SQSC). METHODS Both arterial (AC) and central venous (CVC) catheters were studied. On clinicians' suspicion of CR-BSI, the CVC and AC were removed. Superficial semi-quantitative cultures were taken by removing the dressings and swabbing within a 3cm radius of the CVC and AC insertion sites, as well as inside each hub of the CVC and AC. Peripheral blood was taken for qualitative culture and the catheter tip sent for semi-quantitative culture. DTP was considered positive if culture of lumen blood became positive at least 120min before peripheral blood with an identical pathogen. Superficial and tip cultures were identified as positive if ≥15 CFUs were grown. CR-BSI was confirmed when both catheter tip culture and peripheral blood culture were positive with the same micro-organism. RESULTS Sixteen patients (88% male) with an APACHE II score of 22.0 (7.3) were enrolled. The mean age was 45.7 (16.9) years with mean total burn surface area 32.9 (19.4)%. Fifty percent had airway burns. ICU stay was 19.9 (11.1) days. All 16 survived ICU discharge with a hospital survival of 93%. There were 20 episodes of CR-BSI in these 16 patients. For these 20 episodes the exposure time (line days) was 113.15. The CR-BSI rate was 15.6 per 1000 catheter days (95% CI 1.9-56.4). For diagnosis of CR-BSI in either AC and CVC, SQSC had a sensitivity of 50% [95% CI 3-97], specificity 83.3% [95% CI 67-93], PPV 14.3 [95% CI 1-58], NPV 96.8 [95% CI 81-100], accuracy of 81.6% [95%CI 65-92] and diagnostic odds ratio 5.0 [95% CI 0.3-91.5]. To diagnose tip colonisation (>15CFU), sensitivity of SQSC was 75% [95% CI 22-99], specificity 88.2% [95%CI 72-96], PPV 42.7 [95% CI 12-80], NPV96.8% [95% CI 81-100], accuracy 86.8% [95% CI 71-95] and diagnostic odds ratio 22.5 [95% CI 1.9-271.9]. For combined DTP blood cultures, sensitivity for CR-BSI was 50% [95% CI 3-97], with specificity 97% [95% CI 82-100], PPV 50% [5% CI 3-97%], NPV 97% [95% CI 82-100], accuracy 94.3% 95% CI 79-99] and diagnostic odds ratio 32 [95% CI 1.1-970.8]. CONCLUSION Both DTP and SQSC displayed high specificity, NPV and accuracy in a population of adult burns patients. These features may make these tests useful for ruling out CR-BSI in this patient group. This study was limited by a low number of events and further research is required.

Abstract
Background.No information is available about the financial impact of central venous catheter (CVC)-associated bloodstream infection (BSI) in Mexico.Objective.To calculate the costs associated with BSI in intensive care units (ICUs) in Mexico City.Design.An 18-month (June 2002 through November 2003), prospective, nested case-control study of patients with and patients without BSI.Setting.Adult ICUs in 3 hospitals in Mexico City.Patients and Methods.A total of 55 patients with BSI (case patients) and 55 patients without BSI (control patients) were compared with respect to hospital, type of ICU, year of hospital admission, length of ICU stay, sex, age, and mean severity of illness score. Information about the length of ICU stay was obtained prospectively during daily rounds. The daily cost of ICU stay was provided by the finance department of each hospital. The cost of antibiotics prescribed for BSI was provided by the hospitals' pharmacy departments.Results.For case patients, the mean extra length of stay was 6.1 days, the mean extra cost of antibiotics was $598, the mean extra hospital cost was $11,591, and the attributable extra mortality was 20%.Conclusions.In this study, the duration of ICU stay for patients with central venous catheter-associated BSI was significantly longer than that for control patients, resulting in increased healthcare costs and a higher attributable mortality. These conclusions support the need to implement preventive measures for hospitalized patients with central venous catheters in Mexico.

Abstract
Objective.To determine the incidence of central venous catheter (CVC)-associated bloodstream infection (CA-BSI) among patients admitted to general medical wards outside the intensive care unit (ICU).Design.Prospective cohort study performed over a 13-month period, from April 1, 2002, through April 30, 2003.Setting.Four selected general medical wards at Barnes-Jewish Hospital, a 1,250-bed teaching hospital in Saint Louis, Missouri.Patients.All patients admitted to 4 general medical wards.Results.A total of 7,337 catheter-days were observed during 33,174 patient-days. The device utilization ratio (defined as the number of catheter-days divided by the number of patient-days) was 0.22 overall and was similar among the 4 wards (0.21, 0.25, 0.19, and 0.24). Forty-two episodes of CA-BSI were identified (rate, 5.7 infections per 1,000 catheter-days). Twenty-four (57%) of the 42 cases of CA-BSI were caused by gram-positive bacteria: 10 isolates (24%) were coagulase-negative staphylococci, 10 (24%) were Enterococcus species, and 3 (7%) were Staphylococcus aureus. Gram-negative bacteria caused 7 infections (17%). Five CA-BSIs (12%) were caused by Candida albicans, and 5 infections (12%) had a polymicrobial etiology. Thirty-five patients (83%) with CA-BSI had nontunneled CVCs in place.Conclusions.Non-ICU medical wards in the study hospital had device utilization rates that were considerably lower than those of medical ICUs, but CA-BSI rates were similar to CA-BSI rates in medical ICUs in the United States. Studies of catheter utilization and on CVC insertion and care should be performed on medical wards. CA-BSI prevention strategies that have been used in ICUs should be studied on medical wards.

Abstract
Safe and reliable venous access is mandatory in modern health care, but central venous catheters (CVCs) are associated with significant morbidity and mortality, This paper describes current Swedish guidelines for clinical management of CVCs The guidelines supply updated recommendations that may be useful in other countries as well. Literature retrieval in the Cochrane and Pubmed databases, of papers written in English or Swedish and pertaining to CVC management, was done by members of a task force of the Swedish Society of Anaesthesiology and Intensive Care Medicine. Consensus meetings were held throughout the review process to allow all parts of the guidelines to be embraced by all contributors. All of the content was carefully scored according to criteria by the Oxford Centre for Evidence-Based Medicine. We aimed at producing useful and reliable guidelines on bleeding diathesis, vascular approach, ultrasonic guidance, catheter tip positioning, prevention and management of associated trauma and infection, and specific training and follow-up. A structured patient history focused on bleeding should be taken prior to insertion of a CVCs. The right internal jugular vein should primarily be chosen for insertion of a wide-bore CVC. Catheter tip positioning in the right atrium or lower third of the superior caval vein should be verified for long-term use. Ultrasonic guidance should be used for catheterisation by the internal jugular or femoral veins and may also be used for insertion via the subclavian veins or the veins of the upper limb. The operator inserting a CVC should wear cap, mask, and sterile gown and gloves. For long-term intravenous access, tunnelled CVC or subcutaneous venous ports are preferred. Intravenous position of the catheter tip should be verified by clinical or radiological methods after insertion and before each use. Simulator-assisted training of CVC insertion should precede bedside training in patients. Units inserting and managing CVC should have quality assertion programmes for implementation and follow-up of routines, teaching, training and clinical outcome. Clinical guidelines on a wide range of relevant topics have been introduced, based on extensive literature retrieval, to facilitate effective and safe management of CVCs.

Abstract
Background Catheter-related bloodstream infection (CRBSI) surveillance serves as a quality improvement measure that is often used to assess performance. We reviewed the total number of microbiological samples collected in three Belgian intensive care units (ICU) in 2009–2010, and we described variations in CRBSI rates based on two factors: microbiological documentation rate and CRBSI definition which includes clinical criterion for coagulase-negative Staphylococcus (CNS) episode. Findings CRBSI rates were 2.95, 1.13 and 1.26 per 1,000 estimated catheter-days in ICUs A, B and C, respectively. ICU B cultured fewer microbiological samples and reported the lowest CRBSI rate. ICU C had the highest documentation rate but was assisted by support available from the laboratory for processing single CNS positive blood cultures. With the exclusion of clinical criterion, CRBSI rates would be reduced by 19%, 45% and 0% in ICUs A, B and C, respectively. Conclusion CRBSI rates may be biased by differences of blood culture sampling and CRBSI definition. These observations suggest that comparisons of CRBSI rates in different ICUs remain difficult to interpret without knowledge of local practices.

Abstract
BACKGROUND Healthcare-associated infections (HAIs) are a major threat to patient safety, and are associated with mortality rates varying from 5% to 35%. Important risk factors associated with HAIs are the use of invasive medical devices (e.g. central lines, urinary catheters and mechanical ventilators), and poor staff adherence to infection prevention practices during insertion and care for the devices when in place. There are specific risk profiles for each device, but in general, the breakdown of aseptic technique during insertion and care for the device, as well as the duration of device use, are important factors for the development of these serious and costly infections. OBJECTIVES To assess the effectiveness of different interventions, alone or in combination, which target healthcare professionals or healthcare organisations to improve professional adherence to infection control guidelines on device-related infection rates and measures of adherence. SEARCH METHODS We searched the following electronic databases for primary studies up to June 2012: the Cochrane Effective Paractice and Organisation of Care (EPOC) Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, and CINAHL. We searched reference lists and contacted authors of included studies. We also searched the Cochrane Database of Systematic Reviews and Database of Abstracts of Reviews of Effectiveness (DARE) for related reviews. SELECTION CRITERIA We included randomised controlled trials (RCTs), non-randomised controlled trials (NRCTs), controlled before-after (CBA) studies and interrupted time series (ITS) studies that complied with the Cochrane EPOC Group methodological criteria, and that evaluated interventions to improve professional adherence to guidelines for the prevention of device-related infections. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed the risk of bias of each included study using the Cochrane EPOC 'Risk of bias' tool. We contacted authors of original papers to obtain missing information. MAIN RESULTS We included 13 studies: one cluster randomised controlled trial (CRCT) and 12 ITS studies, involving 40 hospitals, 51 intensive care units (ICUs), 27 wards, and more than 3504 patients and 1406 healthcare professionals. Six of the included studies targeted adherence to guidelines to prevent central line-associated blood stream infections (CLABSIs); another six studies targeted adherence to guidelines to prevent ventilator-associated pneumonia (VAP), and one study focused on interventions to improve urinary catheter practices. We judged all included studies to be at moderate or high risk of bias.The largest median effect on rates of VAP was found at nine months follow-up with a decrease of 7.36 (-10.82 to 3.14) cases per 1000 ventilator days (five studies and 15 sites). The one included cluster randomised controlled trial (CRCT) observed, improved urinary catheter practices five weeks after the intervention (absolute difference 12.2 percentage points), however, the statistical significance of this is unknown given a unit of analysis error. It is worth noting that N = 6 interventions that did result in significantly decreased infection rates involved more than one active intervention, which in some cases, was repeatedly administered over time, and further, that one intervention involving specialised oral care personnel showed the largest step change (-22.9 cases per 1000 ventilator days (standard error (SE) 4.0), and also the largest slope change (-6.45 cases per 1000 ventilator days (SE 1.42, P = 0.002)) among the included studies. We attempted to combine the results for studies targeting the same indwelling medical device (central line catheters or mechanical ventilators) and reporting the same outcomes (CLABSI and VAP rate) in two separate meta-analyses, but due to very high statistical heterogeneity among included studies (I(2) up to 97%), we did not retain these analyses. Six of the included studies reported post-intervention adherence scores ranging from 14% to 98%. The effect on rates of infection were mixed and the effect sizes were small, with the largest median effect for the change in level (interquartile range (IQR)) for the six CLABSI studies being observed at three months follow-up was a decrease of 0.6 (-2.74 to 0.28) cases per 1000 central line days (six studies and 36 sites). This change was not sustained over longer follow-up times. AUTHORS' CONCLUSIONS The low to very low quality of the evidence of studies included in this review provides insufficient evidence to determine with certainty which interventions are most effective in changing professional behaviour and in what contexts. However, interventions that may be worth further study are educational interventions involving more than one active element and that are repeatedly administered over time, and interventions employing specialised personnel, who are focused on an aspect of care that is supported by evidence e.g. dentists/dental auxiliaries performing oral care for VAP prevention.

Abstract
UNLABELLED We retrospectively analyzed the incidence of thrombotic and infectious complications in relation with the use of central venous catheters (CVCs), in a series of patients with hematological malignancies and low platelet and leucocyte counts. PATIENTS AND METHODS 126 patients with hematological malignancies were analyzed. A total of 207 CVCs were implanted: 137 centrally (CICCs) and 70 peripherally (PICCs). The median duration of the CVCs was 19 days for a total of 4051 catheter-days. Antithrombotic prophylaxis was unfractionated heparin (UFH), 2,500 IU daily by 24 h continuous infusion in 169 CVCs, low molecular weight heparin (LMWH), 3,800 IU daily by single bolus intravenous injection (i.v.) in 21 and warfarin in one. No prophylaxis was given in 16 CVCs. Thrombotic complications developed in 15.5% of the CVCs (7.9 events/1000 catheter days), and the frequency of infectious complications was 10.6% (5.2 events/1000 catheter days). On multivariate analysis thromboses were more frequent and earlier with PICCs than CICCs (p = 0.0001), and in patients on UFH (16.6%) than in LMWH prophylaxis (4.7%), but the last difference was not statistically significant. In conclusions the incidence of thrombotic complications in our series was comparable to that observed in non-thrombocytopenic patients and was significantly higher in those carrying PICC than CICC (p = 0.0001). There were fewer thrombotic events in the patients receiving i.v. LMWH prophylaxis than in those receiving i.v. UFH. The use of anticoagulants was safe and not associated with hemorrhages.

Abstract
OBJECTIVE To assess the risk factors associated with CR-BSI development in critically ill patients with non-tunneled, non-cuffed central venous catheters (CVC) and the prognosis of the episodes of CR-BSI. Design and setting; prospective, observational, multicenter study in nine Spanish Hospitals. PATIENTS All subjects admitted to the participating ICUs from October 2004 to June 2005 with a CVC. INTERVENTIONS None. MEASUREMENT AND RESULTS Overall, 1,366 patients were enrolled and 2,101 catheters were analyzed. Sixty-six episodes of CR-BSI were diagnosed. The incidence of CR-BSI was significantly higher in CVC compared with peripherically inserted central venous catheters (PICVC) without significant differences among the three locations of CVC. In the multivariate analysis, duration of catheterization and change over a guidewire were the independent variables associated with the development of CR-BSI whereas the use of a PICVC was a protective factor. Excluding PICVC, 1,598 conventional CVC were analyzed. In this subset, duration of catheterization, tracheostomy and change over a guidewire were independent risk factors for CR-BSI. A multivariate analysis of predictors for mortality among 66 patients with CRSI showed that early removal of the catheter was a protective factor and APACHE II score at the admission was a strong determinant of in-hospital mortality. CONCLUSIONS Peripherically inserted central venous catheters is associated with a lower incidence of CR-BSI in critically ill patients. Exchange over a guidewire of CVC and duration of catheterization are strong contributors to CR-BSI. Our results reinforce the importance of early catheter removal in critically ill patients with CR-BSI.

Abstract
Blood culture contamination represents an ongoing source of frustration for clinicians and microbiologists alike. Ambiguous culture results often lead to diagnostic uncertainty in clinical management and are associated with increased health care costs due to unnecessary treatment and testing. A variety of strategies have been investigated and employed to decrease contamination rates. In addition, numerous approaches to increase our ability to distinguish between clinically significant bacteremia and contamination have been explored. In recent years, there has been an increase in the application of computer-based tools to support infection control activities as well as provide clinical decision support related to the management of infectious diseases. Finally, new approaches for estimating bacteremia risk which have the potential to decrease unnecessary blood culture utilization have been developed and evaluated. In this review, we provide an overview of blood culture contamination and describe the potential utility of a variety of approaches to improve both detection and prevention. While it is clear that progress is being made, fundamental challenges remain.

Abstract
OBJECTIVE To identify risk factors for recurrent catheter related bloodstream infections (CR-BSIs). The study was undertaken at the University of Utah Hospital and involved patients who had a CR-BSI followed by catheter removal and reinsertion between January 1998 and February 2002. DESIGN A retrospective chart review for the cohort study of catheters initially infected, which were then followed to study risk factors for a subsequent infection. Both central line and peripherally inserted central line catheters were included in the study. A recurrent CR-BSI was defined as positive blood cultures after three negative cultures, coupled with positive catheter tip culture or no other evident new source of infection. RESULTS Twenty-five (34%) of 73 patients had a recurrent CR-BSI. The first CR-BSI occurred a mean of 20.4 days after catheter insertion whereas recurrence developed a mean of 12.1 days after reinsertion (p = 0.392). Coagulase-negative staphylococci (60%) were the most common cause of recurrent infection. The recurrence was more common among the patients who were given blood product transfusion (hazard ratio (HR) 2.3; confidence interval (CI) 1.02-5.67, p = 0.049). In 20 (27%) patients, catheters were changed over a guidewire. The guidewire catheter exchange was not found to be associated with an increased risk of recurrent infection (p = 0.582). CONCLUSION Catheter replacement to a new site, instead of rewiring, was not shown to decrease the risk for recurrent infection. The transfusion of blood products was associated with an increased risk for recurrent infection.

Abstract
BACKGROUND The role of parenteral nutrition (PN) therapy as an independent risk factor for central venous catheter (CVC)-related infection in nonselected adult patients is not well established. The aim of this study was to evaluate PN as a risk factor for central venous catheter-related infection in nonselected adult patients in a general university hospital. METHODS Patients using central venous catheters, exposed or nonexposed to PN, were prospectively followed for development of central venous catheter-related infection. RESULTS One hundred fifty-three patients were studied; 28 developed central venous catheter-related infection. Patients with central venous catheter-related infection presented higher frequency of PN use than patients without infection (60.7 vs 34.4%; p = .010). Multivariate Cox analysis showed that PN (relative risk (RR) = 3.30; 95% confidence interval [CI], 1.30-8.34; p = .012) was the only risk factor for central venous catheter-related infection. Malnutrition (RR = 0.45; 95% CI, 0.15-1.34; p = .152), days of hospitalization before central venous catheter insertion (RR = 1.00; 95% CI, 0.98-1.02; p = .801), and sustained hyperglycemia (RR = 0.49; 95% CI, 0.98-1.21; p = .091) were not significant in the model. Multiple logistic regression revealed that mal-nutrition (odds ratio [OR] = 8.05; 95% CI, 1.85-35.03; p = .005), central venous catheter indication for surgical-related pathology (OR = 7.26; 95% CI, 2.51-21.04; p < .001), sustained hyperglycemia (OR = 4.34; 95% CI, 1.79-10.52; p = .001), and days of hospitalization before central venous catheter insertion (OR = 1.04; 95% CI, 1.01-1.07; p = .004) were associated with PN use after adjustment for Assessment Score Intervention System score (OR = 0.33; 95% CI, 0.14-0.80; p = .014). CONCLUSIONS PN therapy is an independent risk factor for central venous catheter-related infection in nonselected hospitalized adult patients.

Abstract
In patients with central venous catheters (CVCs), catheter-related bloodstream infections (CRBI) are a prominent cause of morbidity, excess hospital costs, and in some cases mortality. The aim of this prospective study was to assess the validity of the Gram stain-acridine orange leukocyte cytospin (AOLC) test for the diagnosis of CRBI in hematopoietic stem cell transplant (HSCT) recipients with nontunnelled CVCs, using the differential-time-to-positivity (DTP)/clinical criteria as the criterion standard to define CRBIs. CVCs were externalized, nontunnelled, polyurethane double lumen catheters (Arrows, Readings, USA). All CVCs were placed in the subclavian vein by the infraclavicular approach, in the operating room. Catheters were inserted percutaneously, using the Seldinger technique. Study catheters were not exchanged over guidewires. Between May 2002 and December 2004, a total of 245 consecutive patients were included. Twenty-six of the 245 patients (10.6%) had CRBI as determined by the DTP method. The Gram stain-AOLC was positive in only two patients (7.6%) with a CRBI. Our results suggest that the Gram stain-AOLC test is not useful for the diagnosis of catheter-related bloodstream infection in HSCT recipients.2006.

Abstract
Advances in the management of cancer, particularly the development of new chemotherapeutic agents, have greatly improved the survival and outcome of patients with hematologic malignancies and solid tumors; overall 5-year survival rates in cancer patients have improved from 39% in the 1960s to 60% in the 1990s.1 However, infection, caused by both the underlying malignancy and cancer chemotherapy, particularly myelosuppressive chemotherapy, remains a persistent challenge.

Abstract
OBJECTIVE To assess clinical safety and accuracy of qualitative blood culture drawn through the hub for ruling out catheter-related infection (CRI). DESIGN AND SETTING Prospective observational study in a surgical intensive care unit. PATIENTS All patients with sepsis of unknown origin and possibly due to a CRI. INTERVENTIONS Blood culture drawn through a central venous catheter (CVC) just before the catheter was cultured. MEASUREMENTS AND RESULTS In 126 patients we investigated 135 cases of sepsis of unknown origin. Using a clinical and bacteriological approach as the reference, the performance of the CVC blood culture was evaluated by the calculation of sensitivity, specificity, and positive and negative predictive values. When CVC blood culture was positive, the time to positivity was considered. Using standard definitions, seven CRIs were diagnosed. CVC blood culture identified five CRIs including the three episodes of catheter-related bacteremia. The method missed two coagulase-negative staphylococcus CRIs without bacteremia. Thirteen false-positive results occurred, including seven bacteremias from a distant source. The CVC blood culture had a sensitivity of 71% (CI 30-95%), specificity of 90% (CI 83-94%), negative predictive value of 98% (CI 93-100%), and positive predictive value of 28% (CI 11-54%). In cases of catheter-related bacteremia the time to positivity of CVC blood culture was 24 h or less. CONCLUSIONS Negative CVC blood culture at 24 h seems useful for management of CVC in selected critically ill surgical patients developing a clinical sepsis. The subsequent risk of catheter-related bacteremia cannot be excluded advocating for an uninterrupted clinical and bacteriological survey.

Abstract
OBJECTIVE To determine the incidence, risk factors, outcome, and pathogens of central venous catheter-related bloodstream infections (CVC-BSIs). DESIGN Prospective study. SETTING Escorts Heart Institute and Research Centre, New Delhi, India. PARTICIPANTS One thousand three hundred fourteen consecutive patients undergoing cardiac operations who were admitted to the intensive care unit with CVC. INTERVENTIONS All patients were assigned into CVC-BSI (n = 35) and non-CVC-BSI (n = 1,279) groups. MEASUREMENT AND MAIN RESULTS Of the 1,314 patients in the study, 35 (2.6%) had CVC-BSI. On univariate analysis, significant risk factors were use of multilumen catheters, coexistent infections, intra-aortic balloon counterpulsation (IABC), total ventilation hours, emergency surgery, acute physiology, age, chronic health evaluation score (APACHE II), and steroids. On multivariate analysis, duration of catheterization (24.5 +/- 10.9 v 6.1 +/- 3.2; p < 0.001), coexistent infections (57.11% v 2.61%; p < 0.001), IABC (77.1% v 4.1%; p = 0.005), and temperature (38.2 +/- 0.6 v 37.4 +/- 0.3; p < 0.001) were independent predictors of CVC-BSI. Pathogens isolated were Escherichia coli (47%), Acinetobacter species (11.7%), Enterobacter species (5.8%), Proteus species (5.8%), methicillin-resistant Staphylococcus species (11.7%), coagulase-negative Staphylococcus species (5.8%), and Candida (11.7%). The mortality rate in CVC-BSI was 22.9% as compared with 0.2% in non-CVC-BSI cases (p < 0.001). CONCLUSION By univariate analysis, the risk factors for CVC-BSI were use of multilumen catheters, duration of catheterization, total ventilation hours, IABC, emergency surgery, APACHE II score, coexistent infections, and steroids. On multivariate analysis, duration of catheterization, IABC, coexistent infections, and temperature were independent predictors of CVC-BSI. The mortality was increased with CVC-BSI.

Abstract
Taurolidine is an antimicrobial agent that was originally used in the local treatment of peritonitis and was shown to be effective in the prevention of catheter-related bloodstream infections (CR-BSI). In this pilot study, we used taurolidine solution as an intravenous (i.v.) lock into the totally implantable intravascular devices of 11 consecutive oncological patients with catheter-related bloodstream infections not responding to systemic antimicrobial chemotherapy. All patients recovered completely from the infection. No adverse drug effects were seen. Three patients were successfully retreated for a recurrent infection. Our data suggest a beneficial role of taurolidine i.v. lock for the therapy of catheter-related bloodstream infections in oncological patients. Taurolidine i.v. lock application is feasible and could especially be useful in infections resistant to antibiotic chemotherapy.

Abstract
OBJECTIVE In 2003, critical care and infectious disease experts representing 11 international organizations developed management guidelines for the diagnosis of infection in sepsis that would be of practical use for the bedside clinician, under the auspices of the Surviving Sepsis Campaign, an international effort to increase awareness and improve outcome in severe sepsis. DESIGN The process included a modified Delphi method, a consensus conference, several subsequent smaller meetings of subgroups and key individuals, teleconferences, and electronic-based discussion among subgroups and among the entire committee. METHODS The modified Delphi methodology used for grading recommendations built on a 2001 publication sponsored by the International Sepsis Forum. We undertook a systematic review of the literature graded along five levels to create recommendation grades from A to E, with A being the highest grade. Pediatric considerations to contrast adult and pediatric management are in the article by Parker et al. on p. S591. CONCLUSIONS Obtaining a precise bacteriological diagnosis before starting antibiotic therapy is, when possible, of paramount importance for the success of therapeutic strategy during sepsis. Two to three blood cultures should be performed, preferably from a peripheral vein, without interval between samples to avoid delaying therapy. A quantitative approach is preferred in most cases when possible, in particular for catheter-related infections and ventilator-associated pneumonia. Diagnosing community-acquired pneumonia is complex, and a diagnostic algorithm is proposed. Appropriate samples are indicated during soft tissue and intraabdominal infections, but cultures obtained through the drains are discouraged.

Abstract
BACKGROUND/AIMS Infection control is of key importance especially in the application of long-term continuous hemodiafiltration (CHDF) involving invasive vascular catheterization to critically ill patients. We investigated hemodialysis catheter-related infections in long-term CHDF. METHODS We examined catheter infections in 54 patients who were admitted to the intensive care unit and underwent CHDF for 2 weeks or longer. RESULTS With a total of 155 catheters (1,071 catheter days) studied, catheter colonization and catheter-related bloodstream infection were noted with an incidence rate of 4.8 and 2.7 per 1,000 catheter days, respectively. No difference in catheter colonization rate was observed depending on the catheterization sites or duration of catheterization. Infections were identified in 39 patients (72%) and blood culture positivity was noted in 25 patients (46%). CONCLUSIONS Since the majority of cases requiring long-term CHDF are complicated with a variety of infections, it is difficult to control infections associated with hemodialysis catheters separately from infections of other types. Systemic infection control should serve as a strategy finally leading to successful control of catheter-related infection.

Abstract
• Background Infected central venous catheters cause morbidity and mortality.• Objective To compare the risk for colonization of central venous catheters used for total parenteral nutrition with that of catheters used for other purposes.• Methods Retrospective review of prospectively acquired data on 260 patients with a stay in a surgical intensive care unit longer than 3 days. Single-lumen catheters used solely for total parenteral nutrition were inserted into the subclavian vein and cared for by a dedicated team. Catheters for other purposes were placed and cared for by other staff. Catheters were cultured if clinical findings suggested infection.• Results Of 854 central venous catheters, 61 (7%) were used for total parenteral nutrition. During 4712 catheter days of observation, 89 catheters of all types were colonized. Risk factors for colonization included duration of catheterization (P < .001), having 3 or more lumens (hazard ratio, 1.7; 95% CI, 1.1–2.6), pulmonary artery catheterization (hazard ratio, 1.7; 95% CI, 1.1–2.7), and placement in the internal jugular vein (hazard ratio, 1.6; 95% CI, 1.1–2.5). Catheters used for total parenteral nutrition (hazard ratio, 0.14; 95% CI, 0.04–0.57) and those in the subclavian vein (hazard ratio, 0.51; 95% CI, 0.3–0.8) were at lower risk of colonization. In a multivariate Cox model, the only significant factor was a 5-fold lower risk of infection for catheters used for total parenteral nutrition (hazard ratio, 0.19; 95% CI, 0.04–0.83).• Conclusion Rates of colonization were lowest for catheters used solely for total parenteral nutrition, suggesting that a team approach improves patients’ care.

PATIENTS Patients requiring a central venous catheter for medical or surgical pathologies between June 2000 and November 2001. INTERVENTIONS Patients in the control group received a conventional benzalkonium-treated double-lumen central venous catheter, while patients in the oligon group received an oligon-treated (polyurethane combined with silver, carbon, and platinum) catheter with the same characteristics. Data collection included demographics, preexisting clinical conditions, main pathology, catheter insertion, and management data. Catheter colonization was defined as the growth of > or = 15 colony-forming units in culture of catheter segments by the roll-plate method, or > or = 1000 colony-forming units for the sonication method, and catheter-related bloodstream infection was defined as isolation of the same organism from the colonized catheter and from the peripheral blood of a patient with clinical signs of bloodstream infection. MEASUREMENTS AND MAIN RESULTS Data were obtained from 545 catheters. Of these, 132 catheters (24.2%) were positive for colonization. Patients in the oligon group demonstrated a lower risk for catheter colonization in the overall population (relative risk, 0.63; 95% confidence interval, 0.46-0.86; p = .003) and in the surgical subgroup (relative risk, 0.5; 95% confidence interval, 0.33-0.76;p = .001). Significant differences between groups were detected for coagulase-negative staphylococci and Gram-negative bacilli colonization rates. Twenty-one patients (3.8%) were positive for catheter-related bloodstream infection, without significant differences between control and oligon groups. CONCLUSIONS Oligon treatment is effective in limiting the catheter colonization rate. Due to the limited amount of events, this study lacked the power to detect significant differences in terms of catheter-related bloodstream infection rate.

Abstract
Catheter-related bacteremia is a major complication in patients with long-term surgically implanted central venous catheters, which are difficult and expensive to remove. Conventional treatment fails in a significant number of cases, resulting in removal of the device. The antibiotic-lock technique involves instilling a high concentration of antibiotic into the catheter lumen, and allowing it to remain for a period of time. Results of several open studies, mainly involving patients receiving home parenteral nutrition, indicate that this method may be regarded as an alternative to the conservative treatment of noncomplicated intraluminal catheter-related bacteremia, in which infection may be treated without catheter removal. However, many questions about this therapeutic method remain to be resolved, including appropriate concentration of antibiotics, duration of treatment, and whether or not concomitant systemic antibiotic therapy is necessary. Prospective studies comparing the antibiotic-lock technique with conventional treatment are needed.

Abstract
Intra-vascular access is an unavoidable tool in sophisticated modern medical practice, and catheter-related infection remains a leading cause of nosocomial infections, particularly in intensive care units where it is associated with significant patient morbidity, mortality, and additional hospital costs. The incidence of catheter-related bloodstream infection ranges from 2 to 14 episodes per 1000 catheter-days. On average, microbiologically documented, device-related bloodstream infections complicate the use of a central venous line in three to five per 100 cases. But this represents only the visible part of the iceberg and most episodes of clinical sepsis are nowadays considered to be catheter-related. We briefly review the pathophysiology of these infections, highlighting the importance of the skin insertion site and the intravenous line hub as principal sources of colonization and infection. Principles of therapy are briefly addressed. A large proportion of these infections are preventable and this has been the objective of creating precise guidelines. It was recently suggested that the situation may evolve with the introduction of antibiotic/antiseptic-coated devices, whose impact on the epidemiology of antibiotic resistance remains to be determined. Recently, educational programs and/or a global preventive strategy based on the strict application of specific preventive measures and careful control of all factors associated with infection proved to be even more effective than coated devices in reducing rates of infection. Practical aspects regarding educational approaches will help clinicians to adapt and incorporate educational programs into clinical practice.

Abstract
Intravascular catheters have become essential tools for the management of patients in modern medical practice, but there are complications. In particular, catheter-related infection remains a major cause of nosocomial infection and primary septicemia. The development of preventive strategies to reduce the incidence of catheter-related infection is an important goal for all health providers. Over recent years, significant advances in prophylactic measures for the prevention of catheter-related infection have been made. This paper reviews strategies based on antibiotic prophylaxis such as systemic administration of antibiotics, application of antibiotic ointments to the skin insertion site as well as catheter flushing with antibiotics, the antibiotic-lock technique and the use of antimicrobial impregnated catheters.

Abstract
Intravascular devices (IVDs) are widely used in modern day health care. Unfortunately, their use is associated with substantial risk of bloodstream infection (BSI) and sepsis, with increased hospitalization and hospital mortality. IVDs are the most common cause of nosocomial BSI. The wider use of new methodologies for diagnosis of IVD-related infection should allow earlier and more focused therapy and, especially, improve the accuracy of surveillance. Of all nosocomial infections, IVD-related BSIs are most amendable to prevention.

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
OBJECTIVE To describe the incidence, indications, insertion sites, duration, and complications of central venous catheter (CVC) insertion in patients in a pediatric emergency department (ED). DESIGN Retrospective chart review. SETTING ED of an urban pediatric teaching hospital. SUBJECTS Patients who had a CVC inserted in the ED from January 1992 to July 1997. RESULTS During the 5.5-year study period, 121 patients were identified. Indications for insertion were cardiac/respiratory arrest in 20 patients (17%), lack of peripheral vascular access in 78 (64%), and inadequate peripheral vascular access in 23 (19%). Presenting diagnoses included cardiac/respiratory arrest (20), dehydration (19), lower respiratory tract disease (15), seizure (15), sepsis (13), trauma (10), and other (29). Prior to the CVC insertion, 80 (66%) patients had no venous access, 28 (23%) had a peripheral intravenous catheter, and 13 (11%) had an intraosseous needle. One hundred one (83%) CVCs were inserted into the femoral vein, 12 (10%) into the subclavian, 7 (6%) into the internal jugular, and 1 (1%) into an axillary vein. There were four reported complications requiring the CVC to be removed, and all occurred with femoral line placement. There were no long-term sequelae or life-threatening or limb-threatening complications (95% CI = 0-2.5%). CONCLUSIONS Central venous catheterization, particularly using the femoral approach, appears to a safe method of obtaining central venous access in the critically ill infant, child, or young adult.
