Abstract
OBJECTIVE Despite the effort to increase the proportion of patients starting dialysis on native accesses, many of them are still dialyzed on tunnelled catheter. Catheter-related complications are often serious and responsible for re-hospital admission, high morbidity and mortality. Several multicenter trials have reported results in the use of tunnelled dialysis catheter (TDC). However, few single-center studies have been published to verify the outcome from real-world experience. This study presents our center's experience in managing such patients in the context of relevant literature. METHODS Demographics and operative data were retrospectively collected from medical charts. A prospective follow-up was performed to investigate complications, number of re-hospitalizations and mortality. Kaplan-Meier estimate was used to evaluate catheter primary patency and patients' overall survival. RESULTS Among a total 298 haemodialysis accesses interventions, 105 patients (56 men, 53.3% and 49 women, 46.7%) with a median age of 65 years (range 32-88 years) were included in the study. All insertions were successful with an optimal blood flow achieved during the first session of dialysis in all cases. A catheter-related complication was detected in 33.3% (n=35) patients (48.6% infections; 28.6% TDC dysfunction; 14.3% local complications; 5.7% accidental catheter retractions; 2.8% catheter migrations). At a median follow-up of 10.5±8.5 months, a total of 85 patients (80.9%) was re-hospitalized, in 28 cases (26.7%) for a catheter-related cause. The median catheter patency rate was 122 days. At the last follow-up, 39 patients (37.1%) were still dialyzed on catheter, 30(28.6%) were dialyzed on an arteriovenous fistula and 7(6.7%) received a kidney transplantation. Two patients (2%) were transferred to peritoneal dialysis and two patients (2%) recover from renal insufficiency. Mortality rate was 23.8% (25 patients). Causes of death were myocardial infarction (n=13, 52%), sepsis (n=9, 36%); one patient (4%) died from pneumonia, one (4%) from uremic encephalopathy and one (4%) from massive hematemesis. CONCLUSION TDCs may represent the only possible access in some patients, however they are burned with a high rate of complications, re-hospital admission and mortality. Results from this institutional experience are in line with previously published literature data in terms of morbidity and mortality. The present results reiterate once more that TDC must be regarded as a temporary solution while permanent access creation should be prioritized. Strict surveillance should be held in patients having TDC for the early identification of complications allowing the prompt treatment and modifying the catheter insertion site whenever needed.

Abstract
IMPORTANCE Infection in neonates remains a substantial problem. Advances for this population are hindered by the absence of a consensus definition for sepsis. In adults, the Sequential Organ Failure Assessment (SOFA) operationalizes mortality risk with infection and defines sepsis. The generalizability of the neonatal SOFA (nSOFA) for neonatal late-onset infection-related mortality remains unknown. OBJECTIVE To determine the generalizability of the nSOFA for neonatal late-onset infection-related mortality across multiple sites. DESIGN, SETTING, AND PARTICIPANTS A multicenter retrospective cohort study was conducted at 7 academic neonatal intensive care units between January 1, 2010, and December 31, 2019. Participants included 653 preterm (<33 weeks) very low-birth-weight infants. EXPOSURES Late-onset (>72 hours of life) infection including bacteremia, fungemia, or surgical peritonitis. MAIN OUTCOMES AND MEASURES The primary outcome was late-onset infection episode mortality. The nSOFA scores from survivors and nonsurvivors with confirmed late-onset infection were compared at 9 time points (T) preceding and following event onset. RESULTS In the 653 infants who met inclusion criteria, median gestational age was 25.5 weeks (interquartile range, 24-27 weeks) and median birth weight was 780 g (interquartile range, 638-960 g). A total of 366 infants (56%) were male. Late-onset infection episode mortality occurred in 97 infants (15%). Area under the receiver operating characteristic curves for mortality in the total cohort ranged across study centers from 0.71 to 0.95 (T0 hours), 0.77 to 0.96 (T6 hours), and 0.78 to 0.96 (T12 hours), with utility noted at all centers and in aggregate. Using the maximum nSOFA score at T0 or T6, the area under the receiver operating characteristic curve for mortality was 0.88 (95% CI, 0.84-0.91). Analyses stratified by sex or Gram-stain identification of pathogen class or restricted to infants born at less than 25 weeks' completed gestation did not reduce the association of the nSOFA score with infection-related mortality. CONCLUSIONS AND RELEVANCE The nSOFA score was associated with late-onset infection mortality in preterm infants at the time of evaluation both in aggregate and in each center. These findings suggest that the nSOFA may serve as the foundation for a consensus definition of sepsis in this population.

Abstract
INTRODUCTION The emergence of strains of methicillin-resistant Staphylococcus aureus is a serious therapeutic challenge in healthcare provision. With this study, we aimed to investigate the risk factors and clinical outcomes (mortality and length of hospital stay) associated with methicillin-resistant Staphylococcus aureus infections in patients admitted to a district hospital in Portugal. MATERIAL AND METHODS A case-control study was performed in 96 cases and 122 controls, selected, respectively, as function of antibiotic resistance or sensitivity to methicillin. Data were obtained through consultation of clinical records and subjected to multivariate statistical analysis. RESULTS We identified the following independent risk factors for the occurrence of methicillin-resistant Staphylococcus aureus infection: urinary catheter (aOR = 10.62, 95% CI 3.66 - 30.78), prior use of antibiotics in the last 30 days (aOR = 5.60, 95% CI 2.15 - 14.62), exposure to 5 - 7 days of hospitalization (aOR = 4.99, 95% CI 1.20 - 20.79) or to ≥ 8 days (aOR = 5.34, 95% CI 1.18 - 24.22), chronic obstructive pulmonary disease (aOR = 4.27, 95% CI 1.64 - 11.13) and recent hospitalization (aOR = 2.66, 95% CI 1.14 - 6.23). Compared to infections due to methicillin-susceptible Staphylococcus aureus, we found increased probability of having a longer hospital stay (aHR = 1.74, 95% CI 1.11 - 2.71) and in-hospital mortality was significantly higher (p = 0.001) between patients infected by methicillin-resistant Staphylococcus aureus. DISCUSSION The results demonstrate that methicillin resistance is associated with an increased clinical risk to patients infected by Staphylococcus aureus, in particular, a raised mortality and prolonged hospitalization. CONCLUSION Our study underlines the additional burden imposed by methicillin resistance in Staphylococcus aureus infections. This highlights an urgent need to reinforce and optimize prevention, control, timely detection and effective treatment strategies for multidrug--resistant Staphylococcus aureus strains.

Abstract
INTRODUCTION Peripherally inserted central catheters (PICC-line) are devices inserted through peripheral venous access. In our institution, this technology has been rapidly adopted by physicians in their routine practice. Bacteremia on catheters remains an important public health issue in France. However, the mortality attributable to bacteremia on PICC-line remains poorly evaluated in France and in the literature in general. We report in our study an exhaustive inventory of bacteremia on PICC-line and their 30 days mortality, over a 7 years period. MATERIAL AND METHODS From January 2010 to December 2016, we retrospectively matched PICC-line registers of the radiology department, blood culture records of the microbiology laboratory and medical records from the Hospital Information Systems. RESULTS The 11,334 hospital stays during which a PICC-line was inserted were included over a period of 7 years. Among them, 258 episodes of PICC-line-associated bacteremia were recorded, resulting in a prevalence of 2.27%. Hematology units: 20/324 (6.17%), oncology units: 55/1375 (4%) and hepato-gastro-enterology units: 42/1142 (3.66%) had the highest prevalence of PICC-line related bacteremia. The correlation analysis, when adjusted by exposure and year, shows that the unit profile explains 72% of the variability in the rate of bacteremia with a P = .023. Early bacteremia, occurring within 21 days of insertion, represented 75% of cases. The crude death ratio at 30 days, among patients PICC-line associated bacteremia was 57/11 334 (0.50%). The overall 30-day mortality of patients with PICC-line with and without bacteremia was 1369/11334 (12.07%). On day 30, mortality of patients with bacteremia associated PICC-line was 57/258 or 22.09% of cases, compared to a mortality rate of 1311/11076, or 11.83% in the control group (P < .05, RR 2.066 [1.54-2.75]). Kaplan-Meier survival analysis revealed a statistically significant excess mortality between patients with PICC-line associated bacteremia and PICC-line carriers without bacteremia (P < .0007, hazard ratio 1.89 [1307-2709]). CONCLUSION Patients with PICC-line associated bacteremia have a significant excess mortality. The implementation of a PICC-line should remain the last resort after a careful assessment of the benefit/risk ratio by a senior doctor.

Abstract
BACKGROUND Left ventricular assist device (LVAD)-associated infections may be life-threatening and impact patients' outcome. We aimed to identify the characteristics, risk factors, and prognosis of LVAD-associated infections. METHODS Patients included in the ASSIST-ICD study (19 centers) were enrolled. The main outcome was the occurrence of LVAD-associated infection (driveline infection, pocket infection, or pump/cannula infection) during follow-up. RESULTS Of the 652 patients enrolled, 201 (30.1%) presented a total of 248 LVAD infections diagnosed 6.5 months after implantation, including 171 (26.2%), 51 (7.8%), and 26 (4.0%) percutaneous driveline infection, pocket infection, or pump/cannula infection, respectively. Patients with infections were aged 58.7 years, and most received HeartMate II (82.1%) or HeartWare (13.4%). Most patients (62%) had implantable cardioverter-defibrillators (ICDs) before LVAD, and 104 (16.0%) had ICD implantation, extraction, or replacement after the LVAD surgery. Main pathogens found among the 248 infections were Staphylococcus aureus (n = 113' 45.4%), Enterobacteriaceae (n = 61; 24.6%), Pseudomonas aeruginosa (n = 34; 13.7%), coagulase-negative staphylococci (n = 13; 5.2%), and Candida species (n = 13; 5.2%). In multivariable analysis, HeartMate II (subhazard ratio, 1.56; 95% CI, 1.03 to 2.36; P = .031) and ICD-related procedures post-LVAD (subhazard ratio, 1.43; 95% CI, 1.03-1.98; P = .031) were significantly associated with LVAD infections. Infections had no detrimental impact on survival. CONCLUSIONS Left ventricular assist device-associated infections affect one-third of LVAD recipients, mostly related to skin pathogens and gram-negative bacilli, with increased risk with HeartMate II as compared with HeartWare, and in patients who required ICD-related procedures post-LVAD. This is a plea to better select patients needing ICD implantation/replacement after LVAD implantation.

Abstract
Bloodstream infection caused by Acinetobacter baumannii has become a major clinical concern, especially multidrug-resistant A baumannii (MDRAB). The aim of this study was to identify the risk factors of nosocomial acquired MDRAB bacteremia and to determine the risk factors related to the mortality of patients with MDRAB bacteremia. Patients with nosocomial acquired A baumannii bacteremia were enrolled between January, 2013 and December, 2017 at the First Affiliated Hospital, School of Medicine, Zhejiang University. Medical records were reviewed, and the clinical and microbial characteristics were collected. Among the 338 patients suffering from A baumannii bacteremia, 274 patients were infected with MDRAB bacteremia. Bacteremia-related mortality was 46.4% for the overall sample; 56.2% for MDRAB bacteremia patients, 4.7% for non-MDRAB bacteremia patients. The identified risk factors for developing MDRAB bacteremia were previous exposure to carbapenems [odds ratio (OR) 5.78, P = .005] and penicillins+β-lactamase inhibitors (OR 4.29, P = .009). Primary bacteremia tended to develop non-MDR bacteremia (OR 0.10, P = .002). The risk factors for MDRAB bacteremia-related mortality were old age (OR 1.02, P = .036), a high Pitt bacteremia score (OR 1.32, P < .001), bacteremia occurring after severe pneumonia (OR 8.66, P < .001), while catheter-related infection (OR 0.47, P = .049) and operations for treating infection (OR 0.51, P = .043) may have a better outcome. Patients with MDRAB had a higher mortality rate. Patients with previous carbapenems and penicillins+β-lactamase inhibitor exposure are at an increased risk of MDRAB bacteremia, whereas patients with primary bacteremia tended to develop non-MDR bacteremia. The risk factors for MDRAB bacteremia-related mortality were old age, a high Pitt bacteremia score, and bacteremia occurring after severe pneumonia, whereas catheter-related infection and operations for the treatment of infection may have a better outcome.

Abstract
We retrospectively studied the epidemiology and microbiology of peripheral line-associated bloodstream infection (PLABSI) in comparison with central line-associated bloodstream infection (CLABSI). Among 2,208 bacteremia episodes, 106 (4.8%) PLABSI and 229 (10.4%) CLABSI were identified. In PLABSI, gram-negative rods, especially Enterobacteriaceae, were more frequently identified than in CLABSI, and infectious disease consultation was more frequently involved. The 7-day mortality rate was similar between the 2 groups, suggesting similar adverse effects of PLABSI and CLABSI on patient outcomes.

Abstract
The most common complication in cancer patients is catheter-related bloodstream infection (CRBSI), of which Staphylococcus aureus is a common pathogen. Although S. aureus CRBSI patients are recommended for prolonged intravenous therapy, this is often not feasible. We assessed the effectiveness of switching from intravenous to oral antimicrobial therapy in cancer patients with CRBSI due to methicillin-sensitive S. aureus (MSSA). We conducted a retrospective observational study of 60 patients at one tertiary-care cancer center between April 2005 and March 2016. Patients who received effective intravenous (IV) antibiotics for at least 10 days (IV group) were compared to the IV group of patients who had switched to effective oral (PO) antibiotics after IV treatment for at least 10 days (IV + PO group). The primary endpoint was all-cause mortality within 90 days. Univariate and propensity score-adjusted multivariate logistic regression analyses using variables likely to influence the outcomes were performed. Of the 60 patients, 32 (53.3%) and 28 (46.7%) were in the IV and IV + PO groups, respectively. The median antibiotic treatment durations in the IV and IV + PO groups were 17 (13-31) and 33 (26-52) days, respectively (p<0.001). The 90-day mortality in the IV and IV + PO groups were 53.1% (17/32) and 10.7% (3/28), respectively (p = 0.001). Univariate logistic regression model showed that the odds ratios of oral switch therapy for 90-day mortality was 0.106 (95% confidence interval [CI]: 0.027-0.423; p = 0.001). The propensity score-adjusted multivariate logistic regression model estimated the odds ratios of oral switched therapy for 90-day mortality as 0.377 (95% CI: 0.037-3.884; p = 0.413). Our results suggest that oral switch therapy was not associated with mortality in cancer patients with CRBSI due to MSSA compared with no oral switch therapy. Oral switch therapy may be a reasonable option for patients with CRBSI due to MSSA.

Abstract
BACKGROUND The literature on the outcomes of tunneled femoral catheters compared to that of jugular catheters is scarce and derived mainly from small cohorts. MATERIAL AND METHODS Seven hundred and sixty six catheters were placed in 673 hemodialysis patients, 622 in the jugular/subclavian veins and 144 in the femoral veins. Patients were followed prospectively for 36 months. RESULTS The survival of the tunneled catheters was 771 days 95% CI (737-805) for jugular and 660 days 95% CI (582-739) for femoral veins. Blood flow (0.292 ± 0.003 L/min) and infection rate (0.25 × 1,000 days/catheter) were similar for upper and lower extremities vascular accesses. Factors including sex, age, diabetes and previous catheters did not affect the outcome. CONCLUSIONS Femoral catheters provide outstanding vascular access with excellent, function and low risk of infection.

Abstract
Central-line-associated bloodstream infections (CLABSIs) are responsible for ∼1/3 of all deaths from healthcare-associated infections in the United States. Of these, multidrug-resistant organisms (MDROs) are responsible for 20% to 67%. However, whether catheter removal affects clinical outcomes for MDRO CLABSIs has not been studied. Our objective was to determine the relationship between failure to remove a central venous catheter (CVC) and 30-day all-cause mortality in patients with MDRO CLABSIs. We used a retrospective cohort from Barnes-Jewish Hospital (1/1/2009-10/1/2015) to study patients with a multidrug-resistant Staphylococcus aureus, Enterococcus species, Enterobacteriaceae, Acinetobacter species, or Pseudomonas aeruginosa CLABSI. Risk factors for 30-day mortality, including catheter removal, were assessed for association with 30-day mortality using Cox proportional hazards models. The CLABSIs were assessed prospectively at the time of occurrence by infection prevention specialists. A total of 430 patients met inclusion criteria, 173 (40.2%) with Enterococcus, 116 (27.0%) Enterobacteriaceae, 81 (18.8%) S aureus, 44 (10.2%) polymicrobial, 11 (2.6%) P aeruginosa, and 5 (1.2%) Acinetobacter CLABSIs. Removal of a CVC occurred in 50.2% of patients, of which 4.2% died by 30 days (n = 9). For patients whose CVC remained in place, 45.3% died (n = 97). Failure to remove a CVC was strongly associated with 30-day all-cause mortality with a hazard ratio of 13.5 (6.8-26.7), P < .001. Other risk factors for 30-day mortality included patient comorbidities (cardiovascular disease, congestive heart failure, cirrhosis), and being in an intensive care unit at the time of MDRO isolation. Failure to remove a CVC was strongly associated with 30-day all-cause mortality for patients with MDRO CLABSIs in this single center retrospective cohort. This suggests that patients presenting with MDRO CLABSIs should all undergo CVC removal.

Abstract
Patients with catheter-related bloodstream infection (CRBSI) have a poor prognosis. Proadrenomedullin (pro-ADM) has emerged as a valuable marker of sepsis. The potential role of pro-ADM in predicting the prognosis of CRBSI was evaluated. We enrolled 25 CRBSI patients and pro-ADM level was measured within 24 hours after each admission. Survival was assessed after 28 days. Among 25 patients with CRBSI, 14 patients survived. Pro-ADM in survivors was significantly lower than that in non-survivors (3.71 ± 1.30 vs 5.58 ± 1.18 nmol/L). The area under the curve (AUC) for pro-ADM was 0.87 (95% CI 0.68-0.97) with a cut-off value of 4.67 nmol/L, providing sensitivity of 85.7% and specificity of 81.8%. The AUCs for PCT, WBC, and CRP were 0.76 (95% CI 0.55-0.90), 0.72 (95% CI 0.50-0.88), and 0.69 (95% CI 0.48-0.86), respectively. Kaplan-Meier survival curves showed pro-ADM ≥ 4.67 nmol/L was associated with higher mortality (log-rank p = 0.001). Moreover, the pro-ADM level was significantly higher in patients with septic shock than those without shock (5.44 ± 1.17 vs 3.54 ± 1.18nmol/L). The mortality of patients with septic shock was higher than that of patients without shock (69.2% vs 16.7%, P = .008). In conclusion, pro-ADM could be used as a prognostic marker of CRBSI in critically ill patients.

Abstract
OBJECTIVE To study the impact of a quality improvement (QI) initiative using care bundle approach on Central-line associated bloodstream infections (CLABSI) rates. METHODS A QI team for infection control in NICU was formed in a tertiary-care neonatal intensive care unit (NICU) from June 2015 to August 2016. Baseline data were collected over first 3 months followed by the intervention period of 1 year. Measures with respect to strengthening hand hygiene and central line bundle care were implemented during the intervention period. Audits assessing the compliance to hand hygiene and CLABSI bundle protocols were used as process indicators. Multiple PDSA cycles were used to strengthen the practices of proposed interventions, documentation of data and audits of the processes during the study period. RESULTS The QI initiative achieved a 89% reduction in CLABSI from the baseline rate of 31.7 to 3.5 per 1000 line-days. The blood stream Infections reduced from 7.3 to 2.3 per 1000 patient-days. The overall mortality showed a reduction from 2.9% to 1.7% during the intervention period. There was a significant improvement in compliance with hand hygiene protocol and compliance with CLABSI protocols. CONCLUSION This study demonstrated that simple measures involving hand hygiene and strengthening of the care bundle approach through quality improvement could significantly reduce the blood stream Infections and CLABSI rates.

Abstract
BACKGROUND Central line-associated bloodstream infections (CLABSI) are associated with significant morbidity and mortality. This condition is therefore the focus of quality initiatives, which primarily use audit and feedback to improve performance. However, feedback of quality data inconsistently affects clinician behavior. A hypothesis for this inconsistency is that a lack of comprehension of CLABSI data by decision makers prevents behavior change. In order to rigorously test this hypothesis, a comprehension scale is necessary. Therefore, we sought to develop a scale to assess comprehension of CLABSI quality metric data. METHODS The initial instrument was constructed via an exploratory approach, including literature review and iterative item development. The developed instrument was administered to a sample of clinicians, and each item was scored dichotomously as correct or incorrect. Psychometric evaluation via exploratory factor analyses (using tetrachoric correlations) and Cronbach's alpha were used to assess dimensionality and internal consistency. RESULTS 97 clinicians responded and were included. Factor analyses yielded a scale with one factor containing four items with an eigenvalue of 2.55 and a Cronbach's alpha of 0.82. The final solution was interpreted as an overall CLABSI "comprehension" scale given its unidimensionality and assessment of each piece of data within the CLABSI feedback report. The cohort had a mean performance on the scale of 49% correct (median = 50%). CONCLUSIONS We present the first psychometric evaluation of a preliminary scale that assesses clinician comprehension of CLABSI quality metric data. This scale has internal consistency, assesses clinically relevant concepts related to CLABSI comprehension, and is brief, which will assist in response rates. This scale has potential policy relevance as it could aid efforts to make quality metrics more effective in driving practice change.

Abstract
BACKGROUND Late-onset sepsis is associated with increased rates of mortality and morbidity in newborn infants, in addition to poorer long-term developmental outcomes and increased length of stay and hospital costs. Central line-associated blood stream infection (CLABSI) is the most common cause of late-onset sepsis in hospitalised infants, and prevention of CLABSI is a key objective in neonatal care. Increased frequency of CLABSI around the time of removal of central venous catheters (CVCs) has been reported, and use of antibiotics at the time of removal may reduce the incidence and impact of late-onset sepsis in vulnerable newborn infants. OBJECTIVES To determine the efficacy and safety of giving antibiotics at the time of removal of a central venous catheter (CVC) for reduction of morbidity and mortality in newborn infants, in particular effects on late-onset sepsis. SEARCH METHODS We used the standard search strategy of the Cochrane Neonatal Review Group without language restriction to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 3), MEDLINE via PubMed (1966 to 6 April 2017), Embase (1980 to 6 April 2017), and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1982 to 6 April 2017). We also searched clinical trials databases, conference proceedings, and reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. SELECTION CRITERIA Randomised, quasi-randomised, and cluster-randomised trials considering use of any antibiotic or combination of antibiotics at the time of CVC removal in newborn infants compared with placebo, no antibiotics, or another antibiotic or combination of antibiotics. DATA COLLECTION AND ANALYSIS We extracted data using standard methods of the Cochrane Neonatal Review Group. Two review authors independently selected, assessed the quality of, and extracted data from the included study. MAIN RESULTS Only one randomised controlled trial was eligible for inclusion in this analysis. Forty-four of a total of 88 infants received two doses of cephazolin at the time of removal of CVC compared with no antibiotics at the time of removal of CVC in the control group. No infant in the intervention group developed late-onset sepsis after CVC removal compared with five of 44 (11%) in the control group (risk ratio (RR) 0.09, 95% confidence interval (CI) 0.01 to 1.60). Cephazolin given at the time of removal of CVC did not statistically significantly alter late-onset sepsis rates and led to no significant differences in any of the prespecified outcomes. Review authors judged the study to be of low quality because of high risk of bias and imprecision. AUTHORS' CONCLUSIONS Randomised controlled trials have provided inadequate evidence for assessment of the efficacy or safety of antibiotics given at the time of CVC removal. The single identified trial was underpowered to address this question. Future research should be directed towards targeting use of antibiotics upon removal of CVC for those at greatest risk of complications from CVC removal-related CLABSI. Researchers should include safety data such as impact upon antibiotic use and resistance patterns. This investigation would best occur as part of a bundle of quality improvement care interventions provided by neonatal networks.

Abstract
OBJECTIVE Infectious complications related to external ventricular shunt (ICREVS) are a main problem in neurocritical intensive care units (ICU). The aim of the review is to assess the incidence of ICREVS and to analyse factors involved. METHODS Retrospective analysis, adult polyvalent ICU in a third level reference hospital. Patients carrying external ventricular shunt (DVE) were included. Those patients with central nervous system infection diagnosed prior DVE placement were excluded. RESULTS 87 patients were included with 106 DVE. Most common admittance diagnosis was subarachnoid haemorrhage (49.4%). 31 patients with 32 DVE developed an ICREVS. Infection rate is 19.5 per 1000 days of shunt for ICREVS and 14 per 1000 days for ventriculitis. 31.6% of the patients developed ICREVS and 25.3% ventriculitis. Patients who developed ICREVS presented higher shunt manipulations (2.0 ± 0.6 vs. 3.26 ± 1.02, p=0.02), shunt repositioning (0.1 ± 0.1 vs. 0.2 ± 0.1) and ICU and hospital stay (29.8 ± 4.9 vs 49.8 ± 5.2, p<0.01 y 67.4 ± 18.8 vs. 108.9 ± 30.2, p=0.02. Those DVE with ICREVS were placed for longer not only at infection diagnosis but also at removal (12.6 ± 2.1 vs. 18.3 ± 3.6 and 12.6 ± 2.1 vs. 30.4 ± 7.3 days, p<0.01). No difference in mortality was found. CONCLUSIONS One out of three patients with a DVE develops an infection. The risk factors are the number of manipulations, repositioning and the permanency days. Patients with ICREVS had a longer ICU and hospital average stay without an increase in mortality.

Abstract
BACKGROUND Device-associated health care-associated infections (DA-HAI) pose a threat to patient safety, particularly in the intensive care unit. The aim of this study was to assess the incidence of DA-HAIs, mortality and crude excess mortality at a General Hospital's Intensive Care Unit (ICU) in the Republic of Cyprus for 1 year period. METHODS A prospective cohort, active DA-HAIs surveillance study with the use of Health Acquired Infections (HAIs) ICU Protocol (v1.01 standard edition) as provided by ECDC/NHSN for the active DA-HAIs surveillance study was conducted. The study sample included 198 ICU patients admitted during the research period and hospitalized for over 48 h. The Ventilator-Associated Pneumonia (VAP), Central Line-Associated Bloodstream Infection (CLABSI), and Catheter-Associated Urinary Tract Infection (CAUTI) rates, length of stay (LOS), mortality, and crude excess mortality were calculated. RESULTS CLABSI was the most frequent DA-HAI with 15.9 incidence rate per 1000 Central Venus Catheter (CVC) days. The VAP rate, was 10.1 per 1000 ventilator days and the CAUTI rate was 2.7 per 1000 urinary catheter days. Device associated infections were found to be significantly associated with the length of ICU stay (p < 0.001), the CVC days (p < 0.001), ventilator days (p < 0.001), and urinary catheter days (p < 0.001). The excess mortality was 22.1% for those who acquired a DA-HAI (95% CI, 2-42.2%) compared to the patients who remained DA-HAI free. Mortality of patients with VAP infection was 2.3 times higher (RR = 2.33 95% CI, 1.07-5.05) than those patients admitted without a HAI and subsequently did not acquire a DA-HAI. The most frequently isolated pathogen was Staphylococcus epidermidis (13.9%) and Candida albicans (13.9%). CONCLUSIONS Higher DA-HAIs rates and device utilization than the international benchmarks were found in this study, calling into question the safety of preventative practices employed in this unit.

Abstract
The iron-regulatory hormone hepcidin is induced early in infection, causing iron sequestration in macrophages and decreased plasma iron; this is proposed to limit the replication of extracellular microbes, but could also promote infection with macrophage-tropic pathogens. The mechanisms by which hepcidin and hypoferremia modulate host defense, and the spectrum of microbes affected, are poorly understood. Using mouse models, we show that hepcidin was selectively protective against siderophilic extracellular pathogens (Yersinia enterocolitica O9) by controlling non-transferrin-bound iron (NTBI) rather than iron-transferrin concentration. NTBI promoted the rapid growth of siderophilic but not nonsiderophilic bacteria in mice with either genetic or iatrogenic iron overload and in human plasma. Hepcidin or iron loading did not affect other key components of innate immunity, did not indiscriminately promote intracellular infections (Mycobacterium tuberculosis), and had no effect on extracellular nonsiderophilic Y enterocolitica O8 or Staphylococcus aureus Hepcidin analogs may be useful for treatment of siderophilic infections.

Abstract
BACKGROUND AND OBJECTIVES People receiving hemodialysis to treat kidney failure need a vascular access (a fistula, a graft, or a central venous catheter) to connect to the blood purification machine. Higher rates of access complications are considered the mechanism responsible for the excess mortality observed among catheter or graft users versus fistula users. We tested this hypothesis using mediation analysis. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We studied incident patients who started hemodialysis therapy from North America, Europe, and Australasia (the Dialysis Outcomes and Practice Patterns Study; 1996-2011). We evaluated the association between access type and time to noninfectious (e.g., thrombosis) and infectious complications of the access (mediator model) and the relationship between access type and time-dependent access complications with 6-month mortality from the creation of the first permanent access (outcome model). In mediation analysis, we formally tested whether access complications explain the association between access type and mortality. RESULTS Of the 6119 adults that we studied (mean age =64 [SD=15] years old; 58% men; 47% patients with diabetes), 50% had a permanent catheter for vascular access, 37% had a fistula, and 13% had a graft. During the 6-month study follow-up, 2084 participants (34%) developed a noninfectious complication of the access, 542 (8.9%) developed an infectious complication, and 526 (8.6%) died. Access type predicted the occurrence of access complications; both access type and complications predicted mortality. The associations between access type and mortality were nearly identical in models excluding and including access complications (hazard ratio, 2.00; 95% confidence interval, 1.55 to 2.58 versus hazard ratio, 2.01; 95% confidence interval, 1.56 to 2.59 for catheter versus fistula, respectively). In mediation analysis, higher mortality with catheters or grafts versus fistulas was not the result of increased rates of access complications. CONCLUSIONS Hemodialysis access complications do not seem to explain the association between access type and mortality. Clinical trials are needed to clarify whether these associations are causal or reflect confounding by underlying disease severity.

Abstract
OBJECTIVE To analyse the clinical presentation of candidaemia in elderly patients. METHODS A comparison of clinical presentation of candidaemia cases was carried out in a Spanish tertiary hospital between January 2010 and September 2015. RESULTS Forty-five cases (32%) corresponded to elderly patients (≥ 75 years) and 95 cases (68%) to non-elderly patients (16-74 years). A higher proportion of elderly patients presented solid tumour (51% versus 32%, p=0.026) and a lower proportion had undergone solid or hematopoietic transplantation (0% versus 28%, p<0.001). Fewer elderly patients (16 patients, 36%) had a central venous line inserted than non-elderly patients (81 patients, 85%, p<0.001). Isolation of Candida parapsilosis was significantly lower among elderly (13.3%) than among non-elderly patients (32%, p=0.015). Fundoscopy was carried out in 20 elderly (44%) and in 64 younger patients (67%, p=0.009). The proportion of patients who underwent echocardiography was similar in both groups (56% vs 66%, respectively; p=0.218). Adequate antifungal treatment within the first 48 hours was administered in16 elderly patients (36%) and 58 younger patients (61%, p=0.005). Catheter removal was carried out in 9 elderly patients (68.1%) and in 40 non-elderly patients (49%, p=0.544). Mortality was higher among elderly patients (55.6%) than non-elderly patients (36.8%; p=0.037). CONCLUSIONS Elderly patients account for a substantial proportion of patients suffering from candidaemia in recent years. The clinical management of these patients was less appropriate than in younger patients with respect to fundus examination and the prescription of appropriate antifungal treatment. Mortality in elderly patients was higher than in younger patients.

Abstract
INTRODUCTION Haemodialysis is the only renal replacement therapy available in Cameroon; 95% of patients has received subsidies by the State since 2002 and the number of dialysis centers is growing. However, since the opening of the first center in 1990, there are no data on survival in chronic dialysis patients. METHODS We conducted a multicenter prospective cohort study of 15 months in order to assess mortality rates and factors that influence the survival of chronic hemodialysis patients in Cameroon. RÉSULTS We followed 197 patients of whom 109 were incident patients. The average age was 47,97± 13.19 years and 55% were male. The mean duration of dialysis in prevalent patients was 12.5 months. The mortality rate was 57,58%, 50% of which occurred the first 3 months and abandonment rate was 8.6%. Uremia and catheter-related sepsis were the main causes of death. At a median follow up of 15 months, the overall survival was 30.77%, with an average duration of life of 8 months. Prevalent patients, patient's place of residence where the dialysis center is located, nonfamily management, predialysis follow up > 3 months, blood cholesterol when patient first started on dialysis> 1.5g/l, a mental test score > 25 were associated with a better survival. CONCLUSION In Cameroon, mortality rate in hemodialysis patients is high, with a mean survival time of 8 months; most patients die within the first 3 months.

Abstract
♦ BACKGROUND: There are no large studies that have examined ultra-short break-in period with a blind, bedside, midline approach to Tenckhoff catheter insertion. ♦ METHODS: Observational cohort study of 245 consecutive adult patients who underwent percutaneous catheter insertion for chronic peritoneal dialysis (PD) at our center from January 2009 to December 2013. There were 132 (53.9%) diabetics and 113 (46.1%) non-diabetics in the cohort. ♦ RESULTS: The mean break-in period for the percutaneous group was 2.68 ± 2.6 days. There were significantly more males among the diabetics (103 [78%] vs 66 [58.4%], p = 0.001). Diabetics had a significantly higher body mass index (BMI) (23.9 ± 3.7 kg/m2 vs 22.2 ± 4 kg/m2, p < 0.001) and lower serum albumin (33.1 ± 6.3 g/L vs 37 ± 6 g/L, p < 0.001) compared with non-diabetics. Poor catheter outflow was present in 6 (4.5%) diabetics and 16 (14.2%) non-diabetics (p = 0.009). Catheter migration was also significantly more common in the non-diabetic group (11 [9.7%] vs 2 [1.5%], p = 0.004). Primary catheter non-function was present in 17(15%) of the non-diabetics and in 7(5.3%) of the diabetics (p = 0.01). There were no mortality or major non-procedural complications during the catheter insertions. Among patients with 1 year of follow-up data, catheter survival (93/102 [91.2%] vs 71/82 [86.6%], p = 0.32) and technique survival (93/102 [91.2%] vs 70/82 [85.4%], p = 0.22) at 1 year was comparable between diabetics and non-diabetics, respectively. ♦ CONCLUSIONS: Percutaneous catheter insertion by practicing nephrologists provides a short break-in period with very low mechanical and infective complications. Non-diabetic status emerged as a significant risk factor for primary catheter non-function presumed to be due to more patients with lower BMI and thus smaller abdominal cavities. This is the first report that systematically compares diabetic and non-diabetic patients.

Abstract
Our objective was to compare mortality, epidemiology, and morbidity in hospitalized patients with candidemia which was both related and unrelated to the central venous catheter (CVC). This was a monocentric, retrospective cohort study of candidemia. The sample consisted of 103 patients with laboratory-confirmed nosocomial candidemia hospitalized between 2006 and 2013 in a tertiary care public hospital. We included 65 (63.1 %) patients (24 in the CVC-positive group, 41 in the CVC-negative group). Demographic data and risk factors were recorded using a structured case report form. In the group of candidemia associated to the CVC, survival at day 50 was 58.6 ± 11.9 %, compared to 26.5 ± 8.9 % for the CVC-negative group (p-value = 0.012); the hazard ratio of death was 0.38 (95 % confidence interval 0.17-0.85, p-value = 0.019). Compared with the CVC-positive patients, CVC-negative patients were often colonized with yeast (41.5 % vs. 16.7 %, p-value = 0.041), had a shorter previous in-hospital stay (20 days vs. 34 days, p-value = 0.023), and were more severely ill (severe sepsis 85.4 % vs. 58.3 %, p-value = 0.016). In this study, when the origin of candidemia was not the CVC, patients were more seriously ill, had a higher mortality rate, and the removal of the catheter seemed to lead to disappointing results. It would be useful to explore the impact of retention of the CVC on survival in the CVC-negative patients, where the CVCs are essential to treating these patients.

Abstract
BACKGROUND This study was done to describe the incidence and outcomes of primary hospital-acquired bloodstream infection (HABSI) secondary to Staphylococcus aureus (SA) that did and did not meet the National Healthcare Safety Network's (NHSN's) definition for central line-associated bloodstream infection (CLABSI). METHODS Consecutive hospitalized patients during a 48-month study period with an SA HABSI were categorized according to those who did and did not meet the NHSN's definitions for CLABSI and non-CLABSI. Primary outcomes were mortality at 30 days and 1 year. Secondary outcomes were the incidence of complicated bacteremia and the need for operative intervention secondary to the HABSI event. RESULTS A total of 122 episodes of primary SA HABSIs were identified: 78 (64%) were CLABSIs, and 44 (36%) were non-CLABSIs. Overall 30-day and 1-year mortality in the cohort was 21.3% and 38.5%, respectively, and did not differ significantly between the 2 groups. Complicated SA HABSI was significantly more common in the non-CLABSI group (15.9% [n = 7] vs 0% [n = 0], P ≤ .001). CONCLUSIONS Primary SA HABSI was associated with significant 30-day and 1-year mortality. Complications from SA non-CLABSI requiring surgical intervention were significantly more common than in those with a CLABSI event. Our findings affirm the significance of non-device-related hospital-acquired infections.

Abstract
OBJECTIVE To explore the risk-adjusted association between intensive care unit (ICU)-acquired central line-associated bloodstream infection (CLABSI) and in-hospital mortality. DESIGN Retrospective observational study. SETTING Forty-five-bed adult ICU. PATIENTS All non-extracorporeal membrane oxygenation ICU admissions between July 1, 2008, and April 30, 2014, requiring a central venous catheter (CVC), with a length of stay > 48 hours, were included. METHODS Data were extracted from our infection prevention and ICU databases. A multivariable logistic regression model was constructed to identify independent risk factors for ICU-acquired CLABSI. The propensity toward developing CLABSI was then included in a logistic regression of in-hospital mortality. RESULTS Six thousand three hundred fifty-three admissions were included. Forty-six cases of ICU-acquired CLABSI were identified. The overall CLABSI rate was 1.12 per 1,000 ICU CVC-days. Significant independent risk factors for ICU-acquired CLABSI included: double lumen catheter insertion (odds ratio [OR], 2.59; 95% confidence interval [CI], 1.16-5.77), CVC exposure > 7 days (OR, 2.07; 95% CI, 1.06-4.04), and CVC insertion before 2011 (OR, 2.20; 95% CI, 1.22-3.97). ICU-acquired CLABSI was crudely associated with greater in-hospital mortality, although this was attenuated once the propensity to develop CLABSI was adjusted for (OR, 1.20; 95% CI, 0.54-2.68). CONCLUSIONS A greater propensity toward ICU-acquired CLABSI was independently associated with higher in-hospital mortality, although line infection itself was not. The requirement for prolonged specialized central venous access appears to be a key risk factor for ICU-acquired CLABSI, and likely informs mortality as a marker of persistent organ dysfunction.

Abstract
IMPORTANCE The effectiveness of checklists, daily goal assessments, and clinician prompts as quality improvement interventions in intensive care units (ICUs) is uncertain. OBJECTIVE To determine whether a multifaceted quality improvement intervention reduces the mortality of critically ill adults. DESIGN, SETTING, AND PARTICIPANTS This study had 2 phases. Phase 1 was an observational study to assess baseline data on work climate, care processes, and clinical outcomes, conducted between August 2013 and March 2014 in 118 Brazilian ICUs. Phase 2 was a cluster randomized trial conducted between April and November 2014 with the same ICUs. The first 60 admissions of longer than 48 hours per ICU were enrolled in each phase. INTERVENTIONS Intensive care units were randomized to a quality improvement intervention, including a daily checklist and goal setting during multidisciplinary rounds with follow-up clinician prompting for 11 care processes, or to routine care. MAIN OUTCOMES AND MEASURES In-hospital mortality truncated at 60 days (primary outcome) was analyzed using a random-effects logistic regression model, adjusted for patients' severity and the ICU's baseline standardized mortality ratio. Exploratory secondary outcomes included adherence to care processes, safety climate, and clinical events. RESULTS A total of 6877 patients (mean age, 59.7 years; 3218 [46.8%] women) were enrolled in the baseline (observational) phase and 6761 (mean age, 59.6 years; 3098 [45.8%] women) in the randomized phase, with 3327 patients enrolled in ICUs (n = 59) assigned to the intervention group and 3434 patients in ICUs (n = 59) assigned to routine care. There was no significant difference in in-hospital mortality between the intervention group and the usual care group, with 1096 deaths (32.9%) and 1196 deaths (34.8%), respectively (odds ratio, 1.02; 95% CI, 0.82-1.26; P = .88). Among 20 prespecified secondary outcomes not adjusted for multiple comparisons, 6 were significantly improved in the intervention group (use of low tidal volumes, avoidance of heavy sedation, use of central venous catheters, use of urinary catheters, perception of team work, and perception of patient safety climate), whereas there were no significant differences between the intervention group and the control group for 14 outcomes (ICU mortality, central line-associated bloodstream infection, ventilator-associated pneumonia, urinary tract infection, mean ventilator-free days, mean ICU length of stay, mean hospital length of stay, bed elevation to ≥30°, venous thromboembolism prophylaxis, diet administration, job satisfaction, stress reduction, perception of management, and perception of working conditions). CONCLUSIONS AND RELEVANCE Among critically ill patients treated in ICUs in Brazil, implementation of a multifaceted quality improvement intervention with daily checklists, goal setting, and clinician prompting did not reduce in-hospital mortality.

Abstract
BACKGROUND People admitted to intensive care units and those with chronic health care problems often require long-term vascular access. Central venous access devices (CVADs) are used for administering intravenous medications and blood sampling. CVADs are covered with a dressing and secured with an adhesive or adhesive tape to protect them from infection and reduce movement. Dressings are changed when they become soiled with blood or start to come away from the skin. Repeated removal and application of dressings can cause damage to the skin. The skin is an important barrier that protects the body against infection. Less frequent dressing changes may reduce skin damage, but it is unclear whether this practice affects the frequency of catheter-related infections. OBJECTIVES To assess the effect of the frequency of CVAD dressing changes on the incidence of catheter-related infections and other outcomes including pain and skin damage. SEARCH METHODS In June 2015 we searched: The Cochrane Wounds Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE and EBSCO CINAHL. We also searched clinical trials registries for registered trials. There were no restrictions with respect to language, date of publication or study setting. SELECTION CRITERIA All randomised controlled trials (RCTs) evaluating the effect of the frequency of CVAD dressing changes on the incidence of catheter-related infections on all patients in any healthcare setting. DATA COLLECTION AND ANALYSIS We used standard Cochrane review methodology. Two review authors independently assessed studies for inclusion, performed risk of bias assessment and data extraction. We undertook meta-analysis where appropriate or otherwise synthesised data descriptively when heterogeneous. MAIN RESULTS We included five RCTs (2277 participants) that compared different frequencies of CVAD dressing changes. The studies were all conducted in Europe and published between 1995 and 2009. Participants were recruited from the intensive care and cancer care departments of one children's and four adult hospitals. The studies used a variety of transparent dressings and compared a longer interval between dressing changes (5 to15 days; intervention) with a shorter interval between changes (2 to 5 days; control). In each study participants were followed up until the CVAD was removed or until discharge from ICU or hospital. Confirmed catheter-related bloodstream infection (CRBSI)One trial randomised 995 people receiving central venous catheters to a longer or shorter interval between dressing changes and measured CRBSI. It is unclear whether there is a difference in the risk of CRBSI between people having long or short intervals between dressing changes (RR 1.42, 95% confidence interval (CI) 0.40 to 4.98) (low quality evidence). Suspected catheter-related bloodstream infection Two trials randomised a total of 151 participants to longer or shorter dressing intervals and measured suspected CRBSI. It is unclear whether there is a difference in the risk of suspected CRBSI between people having long or short intervals between dressing changes (RR 0.70, 95% CI 0.23 to 2.10) (low quality evidence). All cause mortalityThree trials randomised a total of 896 participants to longer or shorter dressing intervals and measured all cause mortality. It is unclear whether there is a difference in the risk of death from any cause between people having long or short intervals between dressing changes (RR 1.06, 95% CI 0.90 to 1.25) (low quality evidence). Catheter-site infectionTwo trials randomised a total of 371 participants to longer or shorter dressing intervals and measured catheter-site infection. It is unclear whether there is a difference in risk of catheter-site infection between people having long or short intervals between dressing changes (RR 1.07, 95% CI 0.71 to 1.63) (low quality evidence). Skin damage One small trial (112 children) and three trials (1475 adults) measured skin damage. There was very low quality evidence for the effect of long intervals between dressing changes on skin damage compared with short intervals (children: RR of scoring ≥ 2 on the skin damage scale 0.33, 95% CI 0.16 to 0.68; data for adults not pooled). PainTwo studies involving 193 participants measured pain. It is unclear if there is a difference between long and short interval dressing changes on pain during dressing removal (RR 0.80, 95% CI 0.46 to 1.38) (low quality evidence). AUTHORS' CONCLUSIONS The best available evidence is currently inconclusive regarding whether longer intervals between CVAD dressing changes are associated with more or less catheter-related infection, mortality or pain than shorter intervals.

Abstract
OBJECTIVE The goal of this study was to retrospectively collect data about treatment outcomes in patients diagnosed with Stenotrophomonas maltophilia bacteraemia over a period of 20 years and evaluate these data with respect to the efficacy of treatment options. METHODS The setting was a 700-bed tertiary care hospital in a large urban area. Hospital databases and medical records provided information about episodes of S. maltophilia, patient characteristics and treatment outcomes. Patients with at least one positive blood culture for S. maltophilia were included in the study. Data were analysed with respect to clinical improvement and mortality ≤30 days after the onset of infection. We compared patient characteristics, laboratory values and treatments by using the Chi-square or Fisher's exact tests and the Mann-Whitney test. RESULTS We investigated 27 patients with S. maltophilia bacteraemia. The focus of infection was a central venous catheter in 18 (67 %) cases. The 30-day mortality rate was 11 %. All patients who were treated with an antibiotic that was effective in vitro against the pathogen recovered clinically and survived ≥30 days after the onset of infection. The most frequently used antibiotic was trimethoprim-sulfamethoxazole administered alone or in combination with a fluoroquinolone. CONCLUSIONS Despite the fact that S. maltophilia is resistant to multiple antibiotics, the prognosis for patients with S. maltophilia bacteraemia is good when they are treated with antibiotics that are effective against this pathogen in vitro.

Abstract
BACKGROUND Mechanical catheter dysfunction caused by omentum entrapment remains a major complication of peritoneal dialysis (PD) therapy. The purpose of this study was to determine the outcomes of omentum folding at the time of primary open catheter insertion. METHODS From March 2008 to December 2012, a total of 67 PD subjects were enrolled in the study and randomly assigned to receive either regular open insertion (ROI group, n = 33) or open insertion with omentum folding (OIOF group, n = 34). The primary outcome was defined as PD catheter tip migration with dysfunction. A systematic review was performed to analyze the outcomes of omentum management in PD catheter implantation, based on published data from 1990 to 2013. RESULTS There was no statistical difference in baseline patient characteristics between the ROI and OIOF groups. Nine (27.3%) patients in the ROI group presented with catheter malposition in the late stage (>60 days) of the study, significantly more than in the OIOF group (two; 5.9%) (P = 0.049). Significant differences in catheter survival rate between the two groups were observed in the late stage (P = 0.030) and over the entire study period (P = 0.028). A higher incidence of irreversible catheter dysfunction was shown in the ROI group (15.2%), whereas none occurred in the OIOF group (P = 0.031). No statistical difference was determined in other catheter-related complications or patient survival rate. There were no statistical differences in peritoneal transport characteristics or dialysis adequacy between the two groups upon evaluation at 3, 6 and 12 months. Systemic review of current publications suggested that PD catheter placement with omentum management could lead to less irreversible catheter dysfunction and improved outcome of catheter survival. CONCLUSIONS Our data suggest that omentum folding at the initial time of open catheter placement can significantly reduce the risk of catheter tip migration with dysfunction and improve the outcome of the PD technique.

Abstract
BACKGROUND Catheter-associated urinary tract infections (CAUTIs) have become a major public health concern in the United States. This study provides national estimates of CAUTI incidence, mortality, and associated hospital length of stay (LOS) over a 10-year period. METHODS This was a retrospective analysis of the National Hospital Discharge Surveys from 2001 to 2010. Adults age ≥18 years with an International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) procedure code for urinary catheter placement or other major procedure were included. Urinary tract infections were identified by ICD-9-CM code. Data weights were applied to derive national estimates. Predictors of CAUTI were identified using a logistic regression model. RESULTS These data represent 70.4 million catheterized patients, 3.8 million of whom developed a CAUTI. The incidence of CAUTIs decreased from 9.4 cases/100 catheterizations in 2001 to 5.3 cases/100 catheterizations in 2010. Mortality in patients with a CAUTI declined from 5.4% in 2001 to 3.7% in 2010. Median (interquartile range [IQR]) hospital LOS also declined, from 9 days (IQR, 5-16 days) in 2001 to 7 days (IQR, 4-12 days) in 2010. Independent predictors of CAUTI included female sex, emergency hospital admission, transfer from another facility, and Medicaid payment (P < .0001 for all variables). CONCLUSIONS The incidence of CAUTIs in US hospitals declined over the study period. Furthermore, patients with these infections experienced lower hospital mortality and shorter hospital LOS.

Abstract
OBJECTIVE The epidemiologic data of catheter related blood stream infections (CRBSI) is different in each type of Intensive Care Unit (ICU). The objectives were to identify microbiological patterns, risk factors and mortality analysis in the surgical intensive care unit (SICU). MATERIAL AND METHOD All CRBSI cases were reviewed in a 60-months period from the 1st ofJanuary, 2005 through the 31st of December, 2009. Two or three control patients, who had been catheterized within three days and were free of CRBSI, were randomly selected from the ICU admissions registration book as the control group; demographic data, mortality, organisms found and antibiotic sensitivity were recorded and analyzed. RESULTS In the 5-years period, 44 patients were diagnosed with a CRBSI and 129 patients who were without a CRBSI were selected. The total infection rate was 1.31 per 1,000 catheter-days. Nine patients who contracted a CRBSI (20.4%) expired. A primary diagnosis of gastrointestinal problems had shown the greatest risk for developing a CRBSI (69.7%). In proportions of gram negative bacteria:gram positive bacteria:fungus, this was measured at 43:36:21 respectively. Staphylococcus aureus was the most common gram positive bacteria found. Klebsiella pneumoniae, Enterobacter cloacae and Pseudomonas aeruginosa were the three most common gram negative bacteria found. The chance of developing a CRBSI was significantly increased after 10 days of catheterization. The mortality probability of gram negative bacterial infections and fungal infections increased over time. This was in contrast to gram positive bacterial infections, which decreased over time despite having shown the highest possibility of death earlier in catheter days. As for multivariable analyses, catheterization of patients in the general wards was the sole independent risk factor of CRBSI occurrences (OR = 8.67, p < 0.01) and the males (OR = 7.20, p = 0.03) have shown the highest risk factors for mortality. CONCLUSION The occurrence of gram-negative bacteria and gram-positive bacteria related CRBSI was similar but the probability patterns of increasing the catheter days relating to CRBSI occurrence and mortality rates were different. Catheterization in the general wards was the only independent risk factor found for contracting a CRBSI in our institute. Males had the highest risk for mortality.

Abstract
BACKGROUND/AIMS The high mortality attributable to persistent methicillin-resistant Staphylococcus aureus (MRSA) bacteremia in spite of glycopeptide treatment has heightened the need for early detection and intervention with alternative agents. The purpose of this study was to determine the clinical characteristics of and risk factors for persistent MRSA bacteremia. METHODS All first episodes of significant MRSA bacteremia at a 710-bed academic medical center from November 2009 through August 2010 were recorded. Blood cultures were conducted at 3 days and every 2 to 3 days thereafter until clearance. Clinical characteristics and outcomes were compared between persistent MRSA bacteremia (≥ 7 days) and nonpersistent MRSA bacteremia (≤ 3 days). RESULTS Of 79 patients with MRSA bacteremia during the study period, 31 (39.2%) had persistent MRSA bacteremia. The persistent MRSA bacteremia group had significantly higher 30-day mortality than the nonpersistent MRSA bacteremia group (58.1% vs. 16.7%, p < 0.001). Multivariate analysis indicated that metastatic infection at presentation (odds ratio [OR], 14.57; 95% confidence interval [CI], 3.52 to 60.34; p < 0.001) and delayed catheter removal in catheter-related infection (OR, 3.80; 95% CI, 1.04 to 13.88; p = 0.004) were independent predictors of persistent MRSA bacteremia. Patients with a time to blood culture positivity (TTP) of < 11.8 hours were at increased risk of persistent MRSA bacteremia (29.0% vs. 8.3%, p = 0.029). CONCLUSIONS High mortality in patients with persistent MRSA bacteremia was noted. Early detection of metastatic infection and early removal of infected intravascular catheters should be considered to reduce the risk of persistent MRSA bacteremia. Further studies are needed to evaluate the role of TTP for predicting persistent MRSA bacteremia.

Abstract
BACKGROUND The tubing (administration set) attached to both venous and arterial catheters may contribute to bacteraemia and other infections. The rate of infection may be increased or decreased by routine replacement of administration sets. This review was originally published in 2005 and was updated in 2012. OBJECTIVES The objective of this review was to identify any relationship between the frequency with which administration sets are replaced and rates of microbial colonization, infection and death. SEARCH METHODS We searched The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 6), MEDLINE (1950 to June 2012), CINAHL (1982 to June 2012), EMBASE (1980 to June 2012), reference lists of identified trials and bibliographies of published reviews. The original search was performed in February 2004. We also contacted researchers in the field. We applied no language restriction. SELECTION CRITERIA We included all randomized or controlled clinical trials on the frequency of venous or arterial catheter administration set replacement in hospitalized participants. DATA COLLECTION AND ANALYSIS Two review authors assessed all potentially relevant studies. We resolved disagreements between the two review authors by discussion with a third review author. We collected data for seven outcomes: catheter-related infection; infusate-related infection; infusate microbial colonization; catheter microbial colonization; all-cause bloodstream infection; mortality; and cost. We pooled results from studies that compared different frequencies of administration set replacement, for instance, we pooled studies that compared replacement ≥ every 96 hours versus every 72 hours with studies that compared replacement ≥ every 48 hours versus every 24 hours. MAIN RESULTS We identified 26 studies for this updated review, 10 of which we excluded; six did not fulfil the inclusion criteria and four did not report usable data. We extracted data from the remaining 18 references (16 studies) with 5001 participants: study designs included neonate and adult populations, arterial and venous administration sets, parenteral nutrition, lipid emulsions and crystalloid infusions. Most studies were at moderate to high risk of bias or did not adequately describe the methods that they used to minimize bias. All included trials were unable to blind personnel because of the nature of the intervention.No evidence was found for differences in catheter-related or infusate-related bacteraemia or fungaemia with more frequent administration set replacement overall or at any time interval comparison (risk ratio (RR) 1.06, 95% confidence interval (CI) 0.67 to 1.69; RR 0.67, 95% CI 0.27 to 1.70). Infrequent administration set replacement reduced the rate of bloodstream infection (RR 0.73, 95% CI 0.54 to 0.98). No evidence revealed differences in catheter colonization or infusate colonization with more frequent administration set replacement (RR 1.08, 95% CI 0.94 to 1.24; RR 1.15, 95% CI 0.70 to 1.86, respectively). Borderline evidence suggested that infrequent administration set replacement increased the mortality rate only within the neonatal population (RR 1.84, 95% CI 1.00 to 3.36). No evidence revealed interactions between the (lack of) effects of frequency of administration set replacement and the subgroups analysed: parenteral nutrition and/or fat emulsions versus infusates not involving parenteral nutrition or fat emulsions; adult versus neonatal participants; and arterial versus venous catheters. AUTHORS' CONCLUSIONS Some evidence indicates that administration sets that do not contain lipids, blood or blood products may be left in place for intervals of up to 96 hours without increasing the risk of infection. Other evidence suggests that mortality increased within the neonatal population with infrequent administration set replacement. However, much the evidence obtained was derived from studies of low to moderate quality.

Abstract
BACKGROUND Little data exist on the burden of device-associated health care-associated infection (DA-HAI) in China. This study examined the DA-HAI rate and evaluated its association with device use (DU), length of stay (LOS), and mortality in intensive care units (ICUs) in 4 Chinese hospitals. METHODS This was a prospective cohort surveillance study conducted in 7 ICUs in 4 hospitals. We applied International Nosocomial Control Consortium methods and Centers for Disease Control and Prevention (CDC)/National Health and Safety Network (NHSN) definitions to determine rates of central line-associated blood stream infection (CLABSI), ventilator-associated pneumonia (VAP), catheter-associated urinary tract infection (CAUTI), DU, crude extra length of hospital stay (LOS), and mortality. RESULTS Between August 2008 and July 2010, there were a total of 2,631 admissions to the 7 ICUs in the study hospitals. The rate of VAP was 10.46/1,000 mechanical ventilator (MV)-days, the CLABSI rate was 7.66/1,000 central line (CL)-days, and the CAUTI rate was 1.29/1,000 urinary catheter (UC)-days. Pooled DU ratios were 0.43 for MV, 0.71 for CL, and 0.76 for UC. Crude extra LOS was 15 days for patients with CLABSI, 20.5 days for patients with VAP, and 27 days for patients with CAUTI. Crude extra mortality was 14% for patients with CLABSI, 22% for patients with VAP, and 43% for patients with CAUTI. CONCLUSIONS In the study ICUs, VAP and CLABSI rates were higher than CDC/NHSN's reported data, and LOS and mortality were increased. Compared with the CDC/NHSN and INICC data, the pooled DU ratio for MV was similar, and DU ratios for CL and UC use ratios were slightly higher.

Abstract
PURPOSE To analyze the impact of primary and catheterrelated bloodstream infections (PBSI/CRBSI) on morbidity and mortality. METHODS A matched case-control study (1:4) was carried out on a Spanish epidemiological database of critically ill patients (ENVIN-HELICS). To determine the risk of death in patients with PBSI/CRBSI a matched Cox proportional hazard regression analysis was performed. RESULTS Out of the 74,585 registered patients, those with at least one episode of monomicrobial PBSI/CRBSI were selected and paired with patients without PBSI/CRBSI for demographic and diagnostic criteria and seriousness of their condition on admission to the Intensive Care Unit (ICU). for mortality analysis, 1,879 patients with PBSI/CRBSI were paired with 7,516 controls. The crude death rate in the ICU was 28.1% among the cases and 18.7% among the controls. Attributable mortality 9.4% (HR:1.20; 95% confidence interval: 1.07-1.34; p<0.001). Risk of death varied according to the source of infection, aetiology, moment of onset of bloodstream infection and severity on admission to the ICU. The median stay in the ICU of patients who survived PBSI/CRBSI was 13 days longer than the controls, also varying according to aetiology, moment of onset of bloodstream infection and severity on admission. CONCLUSIONS Acquisition of PBSI/CRBSI in critically ill patients significantly increases mortality and length of ICU stay, which justifies prevention efforts.

Abstract
BACKGROUND Approximately 250,000 catheter-related bloodstream infections (CRBSIs) occurred in the United States in 2002. These preventable infections unnecessarily increase mortality and prolong hospitalization. This study provides national estimates of CRBSIs over 13 years (1996-2008) and identifies trends in mortality and hospital length of stay. METHODS We analyzed data from the National Hospital Discharge Surveys from 1996 to 2008. Adults ≥20 years of age with an ICD-9-CM code for CRBSI (996.62 or 993.3x) were included. Population estimates were obtained from the US Census Bureau, and incidence rates were reported per 10,000 persons. RESULTS These data represent 1.5 million discharges. CRBSIs increased from 4.3 cases/10,000 persons in 1996 to 7.0 cases/10,000 persons in 2003. Thereafter, rates declined until 2008 (5.1 cases/10,000 persons). Mortality declined from 7.6% in 1996 to 5.9% in 2008. Median hospital length of stay (8 days) remained constant throughout the study period. CONCLUSION CRBSIs in US adults increased from 1996 to 2003 then declined until 2008. Patient mortality also declined throughout the study period, whereas hospital length of stay remained constant.

Abstract
Invasive candidiasis (IC) is a leading cause of morbidity and mortality in preterm infants. Even if successfully treated, IC can cause significant neurodevelopmental impairment. Preterm infants are at increased risk for hematogenous Candida meningoencephalitis owing to increased permeability of the blood-brain barrier, so antifungal treatment should have adequate central nervous system penetration. Amphotericin B deoxycholate, lipid preparations of amphotericin B, fluconazole, and micafungin are first-line treatments of IC. Fluconazole prophylaxis reduces the incidence of IC in extremely premature infants, but its safety has not been established for this indication, and as yet, the product has not been shown to reduce mortality in neonates. Targeted prophylaxis may have a role in reducing the burden of disease in this vulnerable population.

Abstract
INTRODUCTION Catheter sepsis is a constant and serious problem in our hospitals for the cost it generates, both in terms of morbidity and economics. It's becoming more frequent also in peripherally inserted catheters. Our study aims to know the importance and characteristics of peripheral venous catheter bacteremia in a general hospital. MATERIAL AND METHODS Prospective and comparative analysis of all episodes of central and peripheral venous catheter-related bacteraemia, in 2009. RESULTS Twenty-eight episodes of catheter-related bacteraemia in a total of 25 patients. Sixteen episodes originated in central catheter (57.2%), 11 in peripheral (39.3%) and 1 in peripherally inserted central catheter (3.5%). Two cases of exitus directly related to the peripheral catheter infection. ETIOLOGY 13 episodes of S. aureus (3 MRSA), including 8 in peripheral catheter (8/13, 61.5%), 12 episodes of plasma coagulase negative staphylococcus, including 2 in peripheral catheter (2/12, 16.6%). CONCLUSIONS Peripheral catheter-related bacteraemia is an emerging health problem with important clinical and prognostic connotations for patients. It is necessary continuous training on correct handling measures to prevent intravascular catheters infections including peripheral catheters in every hospital ward.

Abstract
INTRODUCTION The most severe complication of parenteral nutrition (PTN) is catheter-related infection (CRI). OBJECTIVES To study the incidence rate and factors associated to CRI. MATERIAL AND METHODS 271 patients followed at the Nutrition Unit for 6 months. The composition of the PTN was calculated according to the metabolic demands. 20.3% received a lipid solution enriched with omega-3 fatty acids (SMOF Fresenius Kabi®) and 79.7% with olive oil (Clinoleic Baxter®). RESULTS The rate of CRI was 25 per 1,000 days of PTN (55 patients: 61.7±17.8 years, 60.3% males, 29.3±10.6 days of hospital stay and 10.4% mortality). Coagulase-negative Staphylococcus was the most frequently isolated microorganism. There were no differences by age, gender, mortality, or composition of the PTN between patients with or without infection. The patients treated with omega-3 received more calories with the PTN, at the expense of higher intake of glucose and lipids. However, the rate of infection was similar, although there was a not significant trend towards a lower infection rate when using the omega-3 composition (14.5% vs. 23.1%, respectively, p = 0.112). The duration of the nutritional support was higher in patients with CRI (13.0 ± 9.7 vs. 9.3 ± 8.1, p = 0.038). Total mortality (16.9%) was independent of the presence or absence of CRI (10.4% vs. 18.7%, p = 0.090) or of the use of omega-3 lipids or olive oil in the PTN (10.9% vs. 18.5%, p = 0.125). CONCLUSION Patients submitted to PTN have a high rate of CRI. The presence of infection is related to the duration of the PTN, being independent of the age, gender, and composition of the solution. The use of omega-3 lipid solutions may be beneficial although further studies are needed to confirm this.

Abstract
PURPOSE To evaluate the impact of country socioeconomic status and hospital type on device-associated healthcare-associated infections (DA-HAIs) in neonatal intensive care units (NICUs). METHODS Data were collected on DA-HAIs from September 2003 to February 2010 on 13,251 patients in 30 NICUs in 15 countries. DA-HAIs were defined using criteria formulated by the Centers for Disease Control and Prevention. Country socioeconomic status was defined using World Bank criteria. RESULTS Central-line-associated bloodstream infection (CLA-BSI) rates in NICU patients were significantly lower in private than academic hospitals (10.8 vs. 14.3 CLA-BSI per 1,000 catheter-days; p < 0.03), but not different in public and academic hospitals (14.6 vs. 14.3 CLA-BSI per 1,000 catheter-days; p = 0.86). NICU patient CLA-BSI rates were significantly higher in low-income countries than in lower-middle-income countries or upper-middle-income countries [37.0 vs. 11.9 (p < 0.02) vs. 17.6 (p < 0.05) CLA-BSIs per 1,000 catheter-days, respectively]. Ventilator-associated-pneumonia (VAP) rates in NICU patients were significantly higher in academic hospitals than in private or public hospitals [13.2 vs. 2.4 (p < 0.001) vs. 4.9 (p < 0.001) VAPs per 1,000 ventilator days, respectively]. Lower-middle-income countries had significantly higher VAP rates than low-income countries (11.8 vs. 3.8 per 1,000 ventilator-days; p < 0.001), but VAP rates were not different in low-income countries and upper-middle-income countries (3.8 vs. 6.7 per 1,000 ventilator-days; p = 0.57). When examined by hospital type, overall crude mortality for NICU patients without DA-HAIs was significantly higher in academic and public hospitals than in private hospitals (5.8 vs. 12.5%; p < 0.001). In contrast, NICU patient mortality among those with DA-HAIs was not different regardless of hospital type or country socioeconomic level. CONCLUSIONS Hospital type and country socioeconomic level influence DA-HAI rates and overall mortality in developing countries.

Abstract
Peritoneal dialysis (PD) is one of the modes of renal replacement therapy being utilized for the management of end-stage renal failure in King Khalid University Hospital, King Saud University, Riyadh, for more than two decades. The aim of this study was to evaluate the complications related to PD as well as its outcome in patients on this mode of therapy during the period between January 2004 and December 2008. There were 72 patients included in the study, of whom 43 were females. The average age was 50.7 ± 30.1 years (14-88 years). Diabetes was the leading cause of end-stage renal disease (ESRD) seen in 40.2% of the study patients. Twenty-eight patients (38.9%) were on continuous ambulatory peritoneal dialysis (CAPD) and 44 (61.1%) were on automated PD (nocturnal intermittent peritoneal dialysis, NIPD or continuous cycler peritoneal dialysis, CCPD). The mean duration on PD of the study patients was 25.5 ± 16.58 months (1-60 months). The peritonitis rate was one episode per 24.51 patient-months or one episode per 2.04 patient-years. The incidence of peritonitis per person-year was calculated as 0.42. The leading causative agent for peritonitis was Staphylococcus (32%). Exit-site infection (ESI) rate was one episode per 56.21 patient-months. The incidence of ESI was 0.214 per person-years. The most common infective organism for ESI was Pseudomonas aeru-ginosa (58.8%). At the end of 5 years, 35 patients were continuing on PD, 13 patients were shifted to hemodialysis (HD), nine patients underwent renal transplantation, and six patients were transferred to other centers. Among the 13 patients who were shifted to HD, four patients had refractory peritonitis, four others had catheter malfunction, three patients had inadequate clearance on PD and two patients had lack of compliance. A total of 11 patients died during the study period, giving an overall mortality rate of 15.27% for the five-year period. Our study suggests that there has been considerable improvement in overall outcome and mortality in patients on PD. Additionally, a marked reduction in the infectious and non-infectious complications was noted with the peritonitis and ESI rates in our center being comparable to other studies and international guidelines.

Abstract
UNLABELLED Infectious complications associated with vascular access are a well known cause of increased morbidity and mortality in hemodialysis patients. The aim of the study was to evaluate the incidence of hemodialysis vascular access infections and patients survival in the group of maintenance hemodialysis patients during a one year observation period. The study group consisted of 213 patients (126 male, 87 female; aged 57.4 +/- 14.9 years being on renal replacement therapy for 54 months; range: 2 to 384 months) treated by maintenance hemodialysis at the Nephrology Department of the University Hospital. From the study group 181 patients (84.9%) had created arterio-venous fistulas (AVF); 28 (13.2%) permanent central venous catheters (CVC) implanted and 4 (1.9%) arterio-venous grafts (AVG). Vascular access infectious complications were monitored during a one year observation period. Infections of CVC were observed in 4 (14.3%) of the patients with CVC; 4 (2.2%) of patients with AVF and 2 (50%) of AVG. In the group of patients with signs of AVF infection the following pathogens were found: S. epidermidis 50%, S. aureus 25% and negative culture in 25%. The common pathogens in the group of patients with AVG were as follows: S. aureus and S. hemoliticus. Patients that had infections of implanted CVCin 75% were found to have Gram-positive bacteria (50% S. aureus, 25% S. coagulazo-negative), while 25% had Gram-negative infections (E. coli). In the analyzed period 30 deaths (14.1%) were noted; 23 (12.7%) in patients with AVF and 7 (25%) with CVC. Mortality due to cardio-vascular events in dialyzed patients using permanent catheters came to 43%; death due to catheter infections 14%. In the group of patients with AVF from 23 deaths 83% were of cardio-vascular origin, and 4% due to infections. No deaths were occurred during the observation period in the group of patients with AVG. One should note that only 4 patients with AVG during the study period were evaluated. CONCLUSIONS 1. Types of vascular access has some influence on infectious complications and survival in the group of hemodialized patients. 2. High rate of CVC infections and associated increased mortality and better patients outcome with AVF, indicate that fistula should be constructed in all cases where it is possible.

Abstract
Since the 1960s, regular hemodialysis (HD) was recognized as a risk factor for the development of infective endocarditis (IE), particularly at vascular access sites. The present report describes our experience at the Etat Major General Agadir, Morocco, of taking care of IE in patients on regular dialysis. A retrospective analysis was made of five cases of IE in patients receiving regular HD having arteriovenous fistula as vascular access. They were sent from four private centers and admitted in our formation between January 2004 and March 2009. Infective endocarditis was detected after 34.5 months following initiation of dialysis. The causative organisms included Staphylococcus and Enterococcus in two cases each and negative blood culture in one case. A recent history of infection (<3 months) of the vascular access was found in three cases. Peripheric embolic phenomena were noted in two cases. A pre-existing heart disease was common and contributed to heart failure. Mortality was frequent due to valvular perforations and congestive heart failure, making the medical treatment alone unsatisfactory. Two patients survived and three of our patients received a prosthetic valve replacement, with a median survival after surgery of 10.3 months/person. The clinical diagnosis of infective endocarditis in regularly dialyzed patients remains difficult, with the presence of vascular calcification as a common risk factor. The vascular catheter infections are the cardinal gateway of pathogenic organisms, which are mainly Staphylococcus. The prognosis is bad and the mortality is significant, whereas medical and surgical treatments are often established in these patients who have many factors of comorbidity.

Abstract
Peritoneal dialysis therapy rapidly expanded in Qatar during the last decade. Peritoneal dialysis related peritonitis remains the leading cause of morbidity and technique failure. The objective of this study was to determine the incidence of peritoneal dialysis related peritonitis in Qatar, during a five year study period. The records of all patients on maintenance peritoneal dialysis from January 1, 2003 to December 31, 2007 were reviewed. Episodes of peritonitis, microbial profile, clinical course and outcome were analyzed. A total of 241 patients were included, males represented 74%, the mean age was 53 + or - 13 years, and 48% of patients were diabetics. During the study period 118 episode of peritonitis were observed, with a mean incidence of 0.24 + or - 0.1 episodes per patient year. Gram-positive organisms were isolated in 40% of episodes, with Staphylococcus epidermidis and Staphylococcus hemolyticus being the commonest organisms, isolated in 21% and 9% of infections, respectively. Escherichia coli was the commonest Gram-negative organism and was isolated in 9% of peritonitis episodes, whereas culture-negative peritonitis represented 28% of all diagnosed infections. Seventy nine percent of peritonitis episodes completely resolved with the use of intraperitoneal antimicrobial therapy. Peritoneal dialysis catheters were removed in 19% of episodes. Peritonitis related mortality rate was 3%, and it was due to Candida spp. and Pseudomonas aeruginosa. Despite its low incidence, peritonitis remained the leading cause of patient dropout. Prompt diagnosis and prudent management as well as psychological support to the patients remained essential to reduce the incidence of technique failure following peritonitis episodes.
