Abstract
BACKGROUND The use of central venous catheters (CVC) is associated with higher morbidity and mortality, related to infectious complications, contributing to poorer clinical outcomes and increased healthcare costs. According to the literature, the incidence of local infections related to CVC for hemodialysis is highly variable. This variability is related to differences in definitions of catheter-related infections. OBJECTIVE To identify signs and symptoms for determining local infections (exit site and tunnel tract infections) used in the literature in tunnelled and nontunnelled CVC for hemodialysis. DESIGN Systematic review METHODS: Structured electronic searches were conducted in five electronic databases, from 1 January 2000-31 August 2022, using key words and specific vocabulary, as well as manual searches in several journals. Additionally, vascular access clinical guidelines and infection control clinical guidelines were reviewed. RESULTS After validity analysis, we selected 40 studies and seven clinical guidelines. The definitions of exit site infection and tunnel infection used in the different studies were heterogeneous. Among the studies, seven (17,5 %) used the definitions of exit site and tunnel infection based on a clinical practice guideline. Three of the studies (7.5 %) used the Twardowski scale definition of exit site infection or a modification. The remaining 30 studies (75 %) used different combinations of signs and symptoms. CONCLUSIONS Definitions of local CVC infections are highly heterogeneous in the revised literature. It is necessary to establish a consensus regarding the definitions of hemodialysis CVC exit site and tunnel infections. REGISTRATION PROSPERO (CRD42022351097).

Abstract
INTRODUCTION Haemodialysis patients with central venous catheter (HD-CVC) are at increased risk of exit site infections (ESIs) and catheter-related bloodstream infections, causing an increase of hospitalisation, morbidity and mortality rates. The main aim of the EXITA Study is to develop and validate an instrument for the early detection of HD-CVC ESIs. METHODS AND ANALYSIS EXITA is a multicentre prospective cohort study to validate the proposed instrument with a sample of 457 HD-CVCs: 92 in the ESI group and 365 in the non-ESI group. Sample size was calculated using Epidat V.4.2 software, with 95% and 90% expected sensitivity and specificity, respectively, an ESI incidence around 20% and 5%-10% precision range. During each haemodialysis session, the absence or presence of each item will be assessed by nurses. If any item is present, a microbiological study of pericatheter skin smears and/or exit site exudate will be carried out. HD-CVC ESI will be diagnosed when the pericatheter skin smears and/or exit site exudate culture are positive (≥15 CFU/mL by semiquantitative Maki's technique or ≥1000 CFU/mL by Cleri's technique). To validate the scale, a logistic regression analysis will be performed: the β coefficients of each of the signs/symptoms of the scale to be validated will be estimated. We will use logit function and calculate ESI probability=elogit ESI/1+elogit ESI. ETHICS AND DISSEMINATION The study has been approved by the Research Ethics Committee with Medical Products of Cantabria (approval code 2019.146). We will obtain informed consent from all participants before data collection. We will publish the study results in a peer-reviewed scientific journal.

Abstract
BACKGROUND Cardiovascular diseases (CVD) and infections are recognized as serious complications in patients with end stage kidney disease. However, little is known about the change over time in incidence of these complications. This study aimed to investigate temporal changes in CVD and infective diseases across more than two decades in chronic dialysis patients. METHODS All patients that initiated peritoneal dialysis (PD) or hemodialysis (HD) between 1996 and 2017 were identified and followed until outcome (CVD, pneumonia, infective endocarditis (IE) or sepsis), recovery of kidney function, end of dialysis treatment, death or end of study (December 31st, 2017). The calendar time was divided into 5 periods with period 1 (1996-2000) being the reference period. Adjusted rate ratios were assessed using Poisson regression. RESULTS In 4285 patients with PD (63.7% males) the median age increased across the calendar periods from 65 [57-73] in 1996-2000 to 69 [55-76] in 2014-2017, (p < 0.0001). In 9952 patients with HD (69.2% males), the overall median age was 71 [61-78] without any changes over time. Among PD, an overall non-significant decreasing trend in rate ratios (RR) of CVD was found, (p = 0,071). RR of pneumonia increased significantly throughout the calendar with an almost two-fold increase of the RR in 2014-2017 (RR 1.71; 95% CI 1.46-2.0), (p < 0.001), as compared to the reference period. The RR of IE decreased significantly until 2009 (RR 0.43; 95% CI 0.21-0.87), followed by a return to the reference level in 2010-2013 (RR 0.87; 95% CI 0.47-1.60 and 2014-2017 (RR 1.1; 95% CI 0.59-2.04). A highly significant (p < 0.001) increase in sepsis was revealed across the calendar periods with an almost 5-fold increase in 2014-2017 (RR 4.69 95% CI 3.69-5.96). In HD, the RR of CVD decreased significantly (p < 0.001) from 2006 to 2017 (RR 0.85; 95% CI 0.79-0.92). Compared to the reference period, the RR for pneumonia was high during all calendar periods (p < 0.05). The RR of IE was initially unchanged (p = 0.4) but increased in 2010-2013 (RR 2.02; 95% CI 1.43-2.85) and 2014-2017 (RR 3.39; 95% CI 2.42-4.75). No significant changes in sepsis were seen. CONCLUSION Across the two last decades the RR of CVD has shown a decreasing trend in HD and PD patients, while RR of pneumonia increased significantly, both in PD and in HD. Temporal trends of IE in HD, and particularly of sepsis in PD were upwards across the last decades.

The impact of hemodialysis on mortality risk and cause of death in Staphylococcus aureus endocarditis. BMC Nephrol 2018; 19:216.

Abstract
Background The risk of infective endocarditis (IE) is markedly increased in patients receiving chronic hemodialysis compared with the general population, but outcome data are sparse. The present study investigated causes and risk factors of mortality in a hemodialysis-treated end-stage kidney disease- (ESKD) and a non-ESKD population with staphylococcus (S.) aureus endocarditis. Methods Hemodialysis-treated ESKD patients with S. aureus endocarditis were identified from Danish National Registries and Non-ESKD patients from The East Danish Database on Endocarditis. For establishing the cause of death The Danish Registry of Cause of Death was used. Independent risk factors of outcome were identified in multivariable Cox regression models. Results One hundred twenty-one hemodialysis patients and 190 non-ESKD patients with S. aureus endocarditis were included during 1996–2012 and 2002–2012, respectively. The all-cause in-hospital mortality was 22.3% in hemodialysis- and 24.7% in non-ESKD patients. One-year mortality, excluding in-hospital mortality, was 26.4% in hemodialysis patients and 15.2% in non-ESKD patients. The hazard ratio of all-cause mortality in hemodialysis was 2.64 (95% CI 1.70–4.10) at > 70 days after admission compared with non-ESKD. Age (HR 1.03 (95% CI 1.02–1.04)) and diabetes mellitus (HR 2.17 (95% CI 1.54–3.10)) were independent risk factors of all-cause mortality. The hazard ratio of cardiovascular death in hemodialysis was 3.20 (95% CI 1.78–5.77) at > 81 days after admission compared with non-ESKD. Age and diabetes mellitus were independently related to cardiovascular death. Conclusion All-cause in-hospital mortality rates were similar in hemodialysis and non-ESKD patients with S. aureus endocarditis whereas one-year mortality rates were significantly increased in the hemodialysis population.

Abstract
Vascular access for haemodialysis is key in renal patients both due to its associated morbidity and mortality and due to its impact on quality of life. The process, from the creation and maintenance of vascular access to the treatment of its complications, represents a challenge when it comes to decision-making, due to the complexity of the existing disease and the diversity of the specialities involved. With a view to finding a common approach, the Spanish Multidisciplinary Group on Vascular Access (GEMAV), which includes experts from the five scientific societies involved (nephrology [S.E.N.], vascular surgery [SEACV], vascular and interventional radiology [SERAM-SERVEI], infectious diseases [SEIMC] and nephrology nursing [SEDEN]), along with the methodological support of the Cochrane Center, has updated the Guidelines on Vascular Access for Haemodialysis, published in 2005. These guidelines maintain a similar structure, in that they review the evidence without compromising the educational aspects. However, on one hand, they provide an update to methodology development following the guidelines of the GRADE system in order to translate this systematic review of evidence into recommendations that facilitate decision-making in routine clinical practice, and, on the other hand, the guidelines establish quality indicators which make it possible to monitor the quality of healthcare.

Abstract
Purpose Data from the United States Renal Data System show about 30% of prevailing hemodialysis (HD) patients use arteriovenous fistulae (AVF), which falls far short of the Kidney Disease Outcomes Quality Initiative (K/DOQI) goals of 40–50%. Recent initiatives to increase the use of AVF in HD patients have been criticized as unachievable under realistic practice conditions. Methods A multidisciplinary effort to increase AVF use was undertaken at an outpatient HD center beginning in 1998. Strategies focused on education and recruitment of patients in both inpatient and outpatient settings, preservation of veins, pre-operative vein mapping, and education of staff. Results AVF rates increased from 32%, to 72% over 6 years. The percentage of prosthetic grafts decreased from 40% to 13%. Central venous catheters fell from 28% to 15%. Among residual patients with catheters, 77% had maturing fistulae, as well. Infection rates in the dialysis unit decreased by 39%. Bacteremia declined by 47%. These improvements have been sustainable over the past 12 months. Conclusions Adherence to a strategic program similar to the Fistula First Initiative can increase fistula rates under ordinary practice conditions. High fistula rates can be achieved in male and female patients. Unanimous commitment among all members of the health care team is needed. Reduction in the risks of infection, bacteremia, endocarditis, and death may be derived from achievable changes in practice.

Abstract
BACKGROUND AND OBJECTIVES Endocarditis is a serious complication in patients treated with RRT. The study aimed to examine incidence and risk factors of endocarditis in patients with ESRD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS The Danish National Registry on Regular Dialysis and Transplantation contains data on all Danish patients receiving renal replacement (hemodialysis, peritoneal dialysis, or kidney transplantation) for ESRD. Incidence of endocarditis was estimated for each RRT modality. Independent risk factors of endocarditis were identified in multivariable Cox regression models. RESULTS From January 1st, 1996 to December 31st, 2012, 10,612 patients (mean age 63 years, 36% female) initiated RRT (7233 hemodialysis, 3056 peritoneal dialysis, 323 pre-emptive kidney transplantation). Endocarditis developed in 267 (2.5%); of these 31 (12%) underwent valve surgery. The overall incidence of endocarditis was 627 per 100,000 person-years in patients receiving RRT. Incidence was higher in patients receiving hemodialysis compared with those receiving peritoneal dialysis or kidney transplantation (1092 per 100,000 person-years, 212 per 100,000 person-years, and 85 per 100,000 person-years, respectively). Adjusted hazard ratios for endocarditis in patients receiving hemodialysis were 5.46 (95% confidence interval [95% CI], 3.28 to 9.10) and 0.41 (95% CI, 0.18 to 0.91) for kidney-transplanted recipients, respectively, as compared with patients in peritoneal dialysis. The incidence of endocarditis in hemodialysis recipients with central venous catheters was more than two-fold higher as compared with those with arteriovenous fistulas. Overall mortality, subsequent to endocarditis, was 22% in-hospital and 51% at 1 year. The first 6 months in RRT, aortic valve disease, and previous endocarditis were identified as significant risk factors of endocarditis. CONCLUSIONS Patients receiving RRT have a high incidence of endocarditis, in particular during hemodialysis treatment using central venous catheters. The first 6 months in RRT, aortic valve disease, and previous endocarditis are significant risk factors for developing endocarditis.

Abstract
Objective.To compare the incidence rates of catheter-related bloodstream infection associated with different vascular access methods in patients receiving hemodialysis.Setting.Tertiary care public hospital in Western Australia.Design.Retrospective analysis of surveillance data collected by the hospital's infection control department.Methods.The number of confirmed bloodstream infections for each type of vascular access was identified for the period from July 2002 through June 2003. The corresponding number of patient-days was determined to calculate the infection incidence rates. The serially correlated data were then analyzed using Poisson generalized estimating equations.Results.A total of 32 confirmed bloodstream infections were identified. Infection rates, in number of infections per 1,000 patient-days, were as follows: 0.4 for native arteriovenous fistulae; 2.86 for synthetic arteriovenous grafts; 4.02 for permanent, tunneled, cuffed central venous catheters; and 20.2 for temporary, nontunneled, noncuffed central venous catheters. Compared with permanent catheters, the monthly infection rate associated with the temporary catheters was significantly higher (incident rate ratio [IRR], 5.025 [95% confidence interval {CI}, 1.532-16.484]; P = .008) and that of arteriovenous fistulae was significantly lower (IRR, 0.099 [95% CI, 0.030-0.324]; P = .001). The monthly infection rate for arteriovenous grafts was not significantly different from that for permanent central venous catheters (IRR, 0.702 [95% CI, 0.246-2.008]; P = .510).Conclusions.A hierarchy of infection risk associated with vascular access type is evident. Native arteriovenous fistulae should be recommended for all patients receiving chronic hemodialysis, to minimize infection.

INTRODUCTION Catheter-related infection (CRI) is a difficult clinical problem in renal medicine, with blood stream infections occurring in up to 40% of patients with haemodialysis (HD) catheters, conferring significant rates of morbidity and mortality. Several approaches have been assessed as a means to prevent CRI. Currently, an intervention that is the source of much discussion is the use of antimicrobial lock solutions (ALS). A number of past conventional meta-analyses have compared different ALS with heparin. However, there is no consensus recommendation regarding which type of ALS is best. The purpose of our study is to carry out a network meta-analysis comparing the efficacy of different ALS for prevention of CRI in patients with HD and ranking these ALS for practical consideration. METHODS AND ANALYSIS We will search six electronic databases, earlier relevant meta-analyses and reference lists of included studies for randomised controlled trials (RCTs) that compared ALS for preventing episodes of CRI in patients with HD either head-to-head or against control interventions using non-ALS. Study selection and data collection will be performed by two reviewers independently. The Cochrane Risk of Bias Tool will be used to assess the quality of included studies. The primary outcome of efficacy will be catheter-related bloodstream infection (CRBSI). We will perform a Bayesian network meta-analysis to compare the relative efficacy of different ALS by WinBUGS (V.1.4.3) and STATA (V.13.0). The quality of evidence will be assessed by GRADE. ETHICS AND DISSEMINATION Ethical approval is not required given that this study includes no confidential personal data and no data on interventions on patients. The results of this study will be submitted to a peer-review journal for publication. TRIAL REGISTRATION NUMBER CRD42015027010.

Abstract
Complexity in the health status of patients with kidney disease forces to seek the aid of medical devices such as the central venous catheter (CVC) that is essential in order to perform hemodialysis. Elementary information about the CVC, as required for the oral healthcare professionals, has been documented so as to serve as a medical manual. This communication is the first of its kind that conjointly delineates vital considerations, which precede dental maneuvers in patients implanted with a CVC.

Abstract
Objective:To describe an outbreak of infections with permanent cuffed hemodialysis catheters recognized through ongoing surveillance and related to a specific malfunctioning permanent catheter.Design:The outbreak was suspected from the results of prospective infection surveillance and confirmed by a retrospective cohort study using medical records for patients receiving dialysis between April 1,1999, and March 31, 2000.Setting:Integrated network of six outpatient hemodialysis facilities in southern Idaho and eastern Oregon.Patients:Outpatients receiving long-term hemodialysis.Results:During the 18 months prior to the outbreak, the overall infection rate was 4.1 infections per 1,000 dialysis sessions with a catheter rate of 8.9 per 1,000 dialysis sessions. During the 7 months of the outbreak, the overall rate increased to 5.8 per 1,000 dialysis sessions, whereas the catheter rate increased to 18.1 per 1,000 dialysis sessions. Reports of malfunctioning “Brand A” catheters prompted discontinuation of their placement. A manufacturer recall occurred in April 2000. During the 14 months after the outbreak, the overall infection rate decreased to 3.3 per 1,000 dialysis sessions and the catheter rate to 10.8 per 1,000 dialysis sessions. A 12-month retrospective cohort study recognized 96 patients with an identifiable catheter brand and 48 infections. Of these, 27 (56%) occurred in patients with Brand A catheters. The relative risk for infection when compared with other catheter brands was 1.96 (95% confidence interval, 1.32 to 2.92; P < .001).Conclusions:Ongoing infection surveillance in hemodialysis facilities can identify specific device-related outbreaks of infections and promote interventions to reduce infectious complications and promote patient safety. Surveillance for vascular access site infections is recommended as a routine activity in hemodialysis facilities.

Abstract
BACKGROUND To estimate patency of arteriovenous fistulas (AVFs) and grafts (AVGs) for dialysis access. METHODS Records of all adult patients who had a dialysis access placed from January 2008 to June 2011 were retrospectively reviewed. RESULTS A total of 494 patients with 655 accesses (390 AVFs, 265 AVGs) were examined. We found that AVG fared worse in assisted primary patency. But AVG had superior secondary patency up to 1.2 years (hazard ratio [HR] .6, confidence interval [CI]: [.4 to .8]) and was no different than AVF after 1.2 years. (HR 1.6, CI: [.9 to 3.1]). On univariate analysis, dialysis catheters negatively impacted assisted primary patency (HR 1.4, CI: [1.09 to 1.77]). CONCLUSIONS AVG can be maintained with higher rates of secondary patency in the short term and are no different in the long term. This result suggests that in patients with limited life expectancy an AVG may be an effective alternative to an AVF to reduce both catheter time and associated complications.

Abstract
BACKGROUND Residing remotely from health care resources appears to impact quality of care delivery. It remains unclear if there are differences in vascular access based on distance of one's residence to dialysis centre at time of dialysis initiation, and whether region or duration of pre-dialysis care are important effect modifiers. METHODS We studied the association of distance from a patients' residence to the nearest dialysis centre and central venous catheter (CVC) use in an observational study of 26,449 incident adult dialysis patients registered in the Canadian Organ Replacement Registry between 2000-2009. Multivariate logistic regression was used to assess the association between distance in tertiles and CVC use, adjusted for patient demographics and comorbidities. Geographic region and duration of pre-dialysis care were examined as potential effect modifiers. RESULTS Eighty percent of patients commenced dialysis with a CVC. Incident CVC use was highest among those living > 20 km from the dialysis centre (OR 1.29 (1.24-1.34)) compared to those living < 5 km from centre. The length of pre-dialysis care and geographic region were significant effect modifiers; among patients residing in the furthest tertile (>20 km) from the nearest dialysis centre, incident CVC use was more common with shorter length of pre-dialysis care (< 1 year) and residence in central regions of the country. CONCLUSION Residing further from a dialysis centre is associated with increased CVC use, an effect modified by shorter pre-dialysis care and the geographic region of the country. Efforts to reduce geographical disparities in pre dialysis care may decrease CVC use.

Abstract
BACKGROUND Infections are an important cause of morbidity and mortality in patients undergoing hemodialysis. Limited information is to be found regarding nosocomial hemodialysis-associated bloodstream infections (HABSI). METHODS We sought to determine the rate of nosocomial HABSI and its associated risk factors at Riverside County Regional Medical Center. Inpatients who received hemodialysis during 2011 and 2012 were included, and outcomes were recorded along with risk factors. Data was analyzed with SPSS Inc software. RESULTS A total of 619 patients was included. Fourteen HABSI were detected, with a rate of 3.33/1,000 hemodialysis sessions and 1.03/1,000 patient-days. An association was detected between HABSI and vascular access type (highest risk with nontunneled catheters), length of hospital stay, number of hemodialysis sessions, and hemoglobin A1c level. A correlation was also noted between HABSI because of MRSA and colonization of nares with MRSA. A predominance of staphylococci infections was detected. CONCLUSION The rate of HABSI observed at Riverside County Regional Medical Center was lower than similar studies (2.5 per 1,000 patient-days and 3.95 per 1,000 hemodialysis sessions). The most important risk factors were determined to be nontunneled catheters, hemoglobin A1c greater than 7%, and nares colonization for HABSI because of MRSA. Infection prevention efforts in the inpatient hemodialysis population should focus on control of hyperglycemia and decolonization of nares from MRSA.

Abstract
BACKGROUND Bloodstream infections (BSIs) cause substantial morbidity in hemodialysis patients. In 2009, the US Centers for Disease Control and Prevention (CDC) sponsored a collaborative project to prevent BSIs in outpatient hemodialysis facilities. We sought to assess the impact of a set of interventions on BSI and access-related BSI rates in participating facilities using data reported to the CDC's National Healthcare Safety Network (NHSN). STUDY DESIGN Quality improvement project. SETTING & PARTICIPANTS Patients in 17 outpatient hemodialysis facilities that volunteered to participate. QUALITY IMPROVEMENT PLAN Facilities reported monthly event and denominator data to NHSN, received guidance from the CDC, and implemented an evidence-based intervention package that included chlorhexidine use for catheter exit-site care, staff training and competency assessments focused on catheter care and aseptic technique, hand hygiene and vascular access care audits, and feedback of infection and adherence rates to staff. OUTCOMES Crude and modeled BSI and access-related BSI rates. MEASUREMENTS Up to 12 months of preintervention (January 2009 through December 2009) and 15 months of intervention period (January 2010 through March 2011) data from participating centers were analyzed. Segmented regression analysis was used to assess changes in BSI and access-related BSI rates during the preintervention and intervention periods. RESULTS Most (65%) participating facilities were hospital based. Pooled mean BSI and access-related BSI rates were 1.09 and 0.73 events per 100 patient-months during the preintervention period and 0.89 and 0.42 events per 100 patient-months during the intervention period, respectively. Modeled rates decreased 32% (P = 0.01) for BSIs and 54% (P < 0.001) for access-related BSIs at the start of the intervention period. LIMITATIONS Participating facilities were not representative of all outpatient hemodialysis centers nationally. There was no control arm to this quality improvement project. CONCLUSIONS Facilities participating in a collaborative successfully decreased their BSI and access-related BSI rates. The decreased rates appeared to be maintained in the intervention period. These findings suggest that improved implementation of recommended practices can reduce BSIs in hemodialysis centers.

Abstract
BACKGROUND National and international guidelines recommend the use of effective vascular access (VA) and infection prevention and control practices within the haemodialysis environment. Establishing an arterio-venous fistula (AVF) and preventing central venous catheter (CVC)-related infections are ongoing challenges for all dialysis settings. We surveyed VA and routine infection prevention and control practices in dialysis units, to provide national data on these practices in Ireland. METHODS A descriptive survey was emailed to nurse managers at all adult (n = 19) and children (n = 1) outpatient haemodialysis units in the Republic of Ireland. Data collected included AVF formation, CVC insertion and maintenance practices, VA use and surveillance of infection and screening protocols. Nineteen of the 20 units responded to the survey. RESULTS The AVF prevalence was 49% for 1370 patients in 17 units who provided these data [mean prevalence per unit: 45.7% (SD 16.2)]; the CVC mean prevalence per unit was 52.5% (SD 16.0). Fourteen dialysis units experienced inadequate access to vascular surgical procedures either due to a lack of dedicated theatre time or hospital beds. Six units administered intravenous prophylactic antimicrobials prior to CVC insertion with only two units using a CVC insertion checklist at the time of catheter insertion. CONCLUSION In general, dialysis units in Ireland show a strong adherence to national guidelines. Compared with the 12 countries participating in the Dialysis Outcomes Practice Patterns Study (DOPPS 4), in 2010, AVF prevalence in Irish dialysis units is the second lowest. Recommendations include establishing an AVF national prevalence target rate, discontinuing the administration of intravenous prophylactic antimicrobials prior to CVC insertion and promoting the use of CVC insertion checklists.

Abstract
The arterio-venous fistula (AVF) is the most common vascular access to perform hemodialysis (HD). The HD venous central catheter use should only be proposed to old patients and/or patients without vascular access construction feasibility. These HD catheters are often responsible of infectious and thrombosis complications. We performed, for the first time in French Polynesia, a retrospective study based on 214 patients receiving 618 HD catheters, to evaluate the infectious complication rate due to HD catheters. We showed that 17.4% of HD catheters present with infection. The number of bacteraemia due to HD catheters is 2.57/1000 days-catheters and the number of infection due to HD catheter is 1.43/1000 days-catheters. Eighteen percent of patients requiring an emergency HD without AVF access are transferred in intensive care unit due to infectious HD catheter complications. We observed a similar bacteriological environment than in literature. However, the number of tunneled HD catheter is really lower to that of the number required in European recommendations and we observed an abnormal number of non-functional AVF 1 month after creation. These results involve our nephrology unit to increase the number of tunneled catheters to limit the infectious risk and also to fit with the best practices guidelines.

Abstract
OBJECTIVES Infection is a common cause of death among hemodialysis patients. The study investigated incidence, risk factors, clinical features and outcome of bloodstream infections (BSIs) in haemodialysis patients. METHODS The records of haemodialysis patients from 1999 to 2005 were reviewed. Risk factors were investigated by multivariate analysis. RESULTS There were identified 148 bacteremic episodes, in 102 patients. The BSI rate was 0.52 per 1000 patient-days. Of the 148 episodes, 34 occurred in patients with permanent fistulae (0.18/1000 patient-days); 19 in patients with grafts (0.39/1000 patient-days); 28 in patients with permanent tunneled central catheters (1.03/1000 patient-days); and 67 in those with temporary-catheter (3.18/1000 patient-days). With fistula as reference, the BSI ratio was 1.84 with arteriovenous graft (P=.029), 4.85 with permanent central venous catheter (P<.001), and 14.88 with temporary catheter (P <.001). Catheter related were 41 episodes (28%). Gram positive organism were responsible for 96 episodes (65%), with S. aureus ( 55%) the most frequent, followed by S. epidermidis (26%) and Gram-negative for 36 (23%), with E. coli (39%) the most frequent. Infection was polymicrobial in 14 (9.5%). Diabetes (p<0.001), low serum albumin (p=0.040) and low hemoglobin (p<0.001) were significant risk factors. During hospitalization 18 patients (18%) died. Septic shock (p<0.001) and polymicrobial infection (p=0.041) were associated with in-hospital mortality. CONCLUSION The risk of BSI in patients undergoing hemodialysis is related to the catheter type and vascular access. Septic shock and polymicrobial infection predispose to unfavourable outcome.

Abstract
PURPOSE A native arteriovenous fistula (AVF) represents the optimal form of Vascular Access (VA) for patients receiving hemodialysis (HD). In Libya there are several barriers to AVF creation including lack of adequate preparation for dialysis and surgical services. We aimed to conduct the first comprehensive study of VA utilisation in HD patients in Libya. METHODS A prospective observational study included all adult patients receiving HD treatment in 25 HD facilities in Libya from May 2009 to Nov 2011. Researchers gathered data regarding VA through interviews with staff and patients as well as medical records. Patients with definitive VA were re-interviewed after 1 year. RESULTS At baseline the majority of patients (91.9%; n=1573) were using permanent VA in the form of AVF or arteriovenous graft. Patients with permanent VA were more likely to be male and less likely to be diabetic than those with CVCs. Most patients had commenced HD using a temporary CVC (91.8%). VA-related complications were: thrombosis (46.7%), aneurysm (22.6%), infection (11.5%) and haemorrhage (10.2%). Incident VA thrombosis was reported by 14.7% in 1 year. Independent risk factors for incident thrombosis were female gender and diabetes. Hospitalisation for VA related complications was reported by 31.4%. CONCLUSIONS Few patients in Libya initiate HD with definitive VA, but most achieve it thereafter. Improved dialysis preparation and increased provision of surgical services are required to increase the proportion of patients initiating HD with definitive VA and should be a priority in rebuilding health services in Libya after the recent conflict.

Abstract
Health care associated infections, the fourth leading cause of disease in industrialised countries, are a major health issue. One part of this condition is based on the increasing insertion and implantation of prosthetic medical devices, since presence of a foreign body significantly reduces the number of bacteria required to produce infection. The most significant hospital-acquired infections, based on frequency and potential severity, are those related to procedures e.g. surgical site infections and medical devices, including urinary tract infection in catheterized patients, pneumonia in patients intubated on a ventilator and bacteraemia related to intravascular catheter use. At least half of all cases of nosocomial infections are associated with medical devices.Modern medical and surgical practices have increasingly utilized implantable medical devices of various kinds. Such devices may be utilized only short-time or intermittently, for months, years or permanently. They improve the therapeutic outcome, save human lives and greatly enhance the quality of life of these patients. However, plastic devices are easily colonized with bacteria and fungi, able to be colonized by microorganisms at a rate of 0.5 cm per hour. A thick biofilm is formed within 24 hours on the entire surface of these plastic devices once inoculated even with a small initial number of bacteria.The aim of the present work is to review the current literature on causes, frequency and preventive measures against infections associated with intravascular devices, catheter-related urinary tract infection, ventilator-associated infection, and infections of other implantable medical devices. Raising awareness for infection associated with implanted medical devices, teaching and training skills of staff, and establishment of surveillance systems monitoring device-related infection seem to be the principal strategies used to achieve reduction and prevention of such infections. The intelligent use of suitable antiseptics in combination with medical devices may further support reduction and prevention of such infections. In addition to reducing the adverse clinical outcomes related with these infections, such reduction may substantially decrease the economic burden caused by device-related infection for health care systems.

Abstract
BACKGROUND Catheter-related bloodstream infections (CRBSIs) account for the majority of hemodialysis-related infections. There are no published data on the efficacy of the chlorhexidine-impregnated foam dressing at reducing the rate of CRBSI among patients undergoing hemodialysis. DESIGN A prospective, nonblinded, crossover intervention trial to determine the efficacy of a chlorhexidine-impregnated foam dressing to reduce the rate of CRBSI among patients undergoing hemodialysis. SETTING Two outpatient dialysis centers. PATIENTS A total of 121 patients who underwent dialysis through tunneled central venous catheters received the intervention during the trial. METHODS The primary outcome of interest was the incidence of CRBSI. A nested cohort study of all patients who received the chlorhexidine-impregnated foam dressing was also conducted. Backward stepwise logistic regression analysis was used to determine independent risk factors for development of CRBSI. RESULTS Thirty-seven CRBSIs occurred in the intervention group, for an incidence of 6.3 CRBSIs per 1,000 dialysis sessions, and 30 CRBSIs occurred in the control group, an incidence of 5.2 CRBSIs per 1,000 dialysis sessions (risk ratio, 1.22 [95% confidence interval {CI}, 0.75-1.97]; P = .46). The chlorhexidine-impregnated foam dressing was well tolerated, with only 2 patients (<2%) experiencing dermatitis that led to its discontinuation. The only independent risk factor for development of CRBSI was dialysis treatment at one dialysis center (adjusted odds ratio, 4.4 [95% CI, 1.77-13.65]; P = .002). Age of at least 60 years (adjusted odds ratio, 0.28 [95% CI, 0.09-0.82]; P = .02) was associated with lower risk of CRBSI. CONCLUSIONS The use of a chlorhexidine-impregnated foam dressing did not decrease the incidence of CRBSI among patients with tunneled central venous catheters who were undergoing hemodialysis.

Abstract
OBJECTIVE To analyze the clinical features of hemodialysis patients complicated by infective endo carditis. METHODS The clinical features of six such patients admitted to Peking Union Medical College Hospital during the year 1990 to 2009 were analyzed. All of them were diagnosed based on Chinese Children Diagnostic Criteria for Infective Endocarditis. RESULTS The average age of the six patients was 52.3 +/- 19.3 years old. Four were males. Vascular accesses at the onset of infective endocarditis were as follows: permanent catheters in three, temporary catheters in two, and arteriovenous fistula in one. Three were found with mitral valve involvement, two with aortic valve involvement, and one with both. Five vegetations were found by transthoracic echocardiography, and one by transesophageal echocardiography. Four had positive blood culture results. The catheters were all removed. Four of the patients were improved by antibiotics treatment, in which two were still on hemodialysis in the following 14-24 months and the other two were lost to follow-up. One patient received surgery, but died of heart failure after further hemodialysis for three months. One was well on maintenance hemodialysis for three months after surgery. CONCLUSIONS Infective endocarditis should be suspected when hemodialysis patients suffer from long-term fever, for which prompt blood culture and transthoracic echocardiography confirmation could be performed. Transesophageal echocardiography could be considered even when transthoracic echocardiography produces negative findings. With catheters removed, full course of appropriate sensitive antibiotics and surgery if indicated could improve the outcome of chronic hemodialysis patients complicated by infective endocarditis.

Abstract
Infections cause significant morbidity and mortality in patients undergoing hemodialysis. Bloodstream infections (BSIs) are particularly problematic, accounting for a substantial number of hospitalizations in these patients. Hospitalizations for BSI and other vascular access infections appear to have increased dramatically in hemodialysis patients since 1993. These infections frequently are related to central venous catheter (CVC) use for dialysis access. Regional initiatives that have shown successful decreases in catheter-related BSIs in hospitalized patients have generated interest in replicating this success in outpatient hemodialysis populations. Several interventions have been effective in preventing BSIs in the hemodialysis setting. Avoiding the use of CVCs in favor of access types with lower associated BSI risk is among the most important. When CVCs are used, adherence to evidence-based catheter insertion and maintenance practices can positively influence BSI rates. In addition, facility-level surveillance to detect BSIs and stimulate examination of vascular access use and care practices is essential to a comprehensive approach to prevention. This article describes the current epidemiology of BSIs in hemodialysis patients and effective prevention strategies to decrease the incidence of these devastating infections.

Abstract
BACKGROUND Central venous catheters (CVC) continue to play a prominent role in haemodialysis vascular access with 46% to 70% of patients commencing haemodialysis via a CVC. CVC access is associated with catheter-related infections, increased patient hospitalisations and death due to infection. A variety of interventions are used to prevent CVC infection. OBJECTIVES To evaluate the benefits and harms of prophylactic topical antimicrobials, topical antiseptics, medicated and non-medicated dressings on infectious complications among haemodialysis patients with CVC. SEARCH STRATEGY We searched the Cochrane Renal Group's specialised register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and reference lists of articles without language restriction. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs investigating any intervention that prevented infectious complications among haemodialysis patients with CVC. We excluded antimicrobial impregnated CVC or CVC using locking solutions with antimicrobial properties. DATA COLLECTION AND ANALYSIS Two authors assessed study quality and extracted data. Dichotomous outcomes were expressed as risk ratios (RR) with 95% confidence intervals (CI) and continuous outcomes as mean differences (MD). MAIN RESULTS Ten studies (786 patients) were included. Mupirocin ointment reduced the risk of catheter-related bacteraemia (RR 0.17, 95%CI 0.07 to 0.43) and had a significant effect on catheter-related infections caused by S. aureus. The risk of catheter-related bacteraemia was reduced by polysporin (RR 0.40, 95%CI 0.19 to 0.86) and povidone-iodine ointment (RR 0.10, 95%CI 0.01 to 0.72). Subgroup analysis suggested mupirocin (RR 0.12, 95%CI 0.01 to 2.13) and povidone-iodine ointment (RR 0.84, 95%CI 0.24 to 2.98) had no effect on all-cause mortality while polysporin ointment showed a significant reduction (RR 0.22, 95%CI 0.07 to 0.74). Mortality related to infection was not reduced by mupirocin, polysporin or povidone-iodine ointment. Topical honey did not reduce the risk of exit site infection (RR 0.45, 95%CI 0.10 to 2.11) or catheter-related bacteraemia (RR 0.80, 95%CI 0.37 to 1.73). Transparent polyurethane dressing compared to dry gauze dressing did not reduce the risk of CVC or exit site infection, or catheter-related bacteraemia. AUTHORS' CONCLUSIONS Mupirocin ointment appears effective in reducing the risk of catheter-related bacteraemia. Insufficient reporting on mupirocin resistance was noted and needs to be considered in future studies. A lack of high quality data on the routine use of povidone-iodine ointment, polysporin ointment and topical honey warrant larger RCTs. Insufficient data were available to determine which dressing type (transparent polyurethane or dry gauze dressing) has the lowest risk of catheter-related infections.

Abstract
In this paper we review the pathogenesis, prevention and management of iatrogenic infection in urological practice. A systematic literature search was conducted using MEDLINE. The topics discussed include the commonest home-care, outpatient, endourologic and open surgical procedures. In addition, we discuss iatrogenic urinary infections associated with special situations, including urinary diversion, urologic prostheses, diabetes mellitus, dialysis, kidney transplantation and complicated urinary tract infections (UTIs). The findings of the literature review are as follows. Prophylactic antibiotics are not recommended with clean intermittent catheterization. With prolonged catheterization, antibiotics should not be used unless symptoms of pyelonephritis or septicemia become apparent. With transrectal prostate biopsy, infection can be prevented by rectal cleansing, use of smaller needles and administration of antimicrobial prophylaxis before and after the procedure. With ureteral stents, antibiotics should be restricted to patients with clinical signs of infection and high-risk patients. Infections after transurethral resection of the prostate can be prevented by avoiding risk factors and using perioperative antibiotics. In endourological procedures, antibiotic prophylaxis is indicated in cases of infected stones, preoperative UTIs or prolonged procedures. Antibiotics are not recommended for clean wounds, as prophylaxis for clean-contaminated wounds or as therapy for contaminated and dirty wounds. In patients with urinary diversion, the objective is to prevent pyelonephritis by avoiding both reflux and obstruction of the upper urinary tract. In patients with urological prostheses, the most important measure to overcome iatrogenic infection is prevention. In dialysis patients, iatrogenic infections can be prevented by the development of new catheter materials that are less susceptible to biofilms. In kidney transplant recipients, iatrogenic infections can be prevented by treating all types of infection prior to transplantation and by using peri- and postoperative prophylactic antibiotics.

Abstract
BACKGROUND Previously, the Dialysis Outcomes and Practice Patterns Study (DOPPS) has shown large international variations in vascular access practice. Greater mortality risks have been seen for hemodialysis (HD) patients dialyzing with a catheter or graft versus a native arteriovenous fistula (AVF). To further understand the relationship between vascular access practice and outcomes, we have applied practice-based analyses (using an instrumental variable approach) to decrease the treatment-by-indication bias of prior patient-level analyses. STUDY DESIGN A prospective observational study of HD practices. SETTING & PARTICIPANTS Data collected from 1996 to 2004 from 28,196 HD patients from more than 300 dialysis units participating in the DOPPS in 12 countries. PREDICTOR OR FACTOR Patient-level or case-mix-adjusted facility-level vascular access use. OUTCOMES/MEASUREMENTS: Mortality and hospitalization risks. RESULTS After adjusting for demographics, comorbid conditions, and laboratory values, greater mortality risk was seen for patients using a catheter (relative risk, 1.32; 95% confidence interval, 1.22 to 1.42; P < 0.001) or graft (relative risk, 1.15; 95% confidence interval, 1.06 to 1.25; P < 0.001) versus an AVF. Every 20% greater case-mix-adjusted catheter use within a facility was associated with 20% greater mortality risk (versus facility AVF use, P < 0.001); and every 20% greater facility graft use was associated with 9% greater mortality risk (P < 0.001). Greater facility catheter and graft use were both associated with greater all-cause and infection-related hospitalization. Catheter and graft use were greater in the United States than in Japan and many European countries. More than half the 36% to 43% greater case-mix-adjusted mortality risk for HD patients in the United States versus the 5 European countries from the DOPPS I and II was attributable to differences in vascular access practice, even after adjusting for other HD practices. Vascular access practice differences accounted for nearly 30% of the greater US mortality compared with Japan. LIMITATIONS Possible existence of unmeasured facility- and patient-level confounders that could impact the relationship of vascular access use with outcomes. CONCLUSIONS Facility-based analyses diminish treatment-by-indication bias and suggest that less catheter and graft use improves patient survival.

Abstract
AIM AND BACKGROUND To show results of the first year of an infection surveillance network for haemodialysis patients (Dialin). In order to improve the security and quality of care, six haemodialysis centers have organized an infection watching network. The purpose of the network is to compare of the watching results between centers. This comparison includes vascular access infection (VAI), bacteraemia and C viral hepatitis. The heterogeneous pattern has been also taken into account. SURVEY TYPE: Multicenter prospective permanent survey. POPULATION Six hundred and sixty-four haemodialyzed chronic patients, followed during one year (2005), in six voluntary haemodialysis centers. This survey has based on 71,688 treatment sessions corresponding to 6257.5 months of haemodialysis (HM). METHODS As with the heterogeneity among centers, the acquired infection standardized ratios (observed/expected) (AISR) and 95% confidence interval are computed with Cox model which includes confounding factors found in literature or in the preliminary stage of the survey. RESULTS VAI crude rate was 0.47 per 100HM, 0.10 per 1000 native fistulae utilisation days, 0.45 per 1000 days of prosthetic graft utilisation and 0.44 per 1000 days of catheter utilisation. Bacteraemia crude incidence rate was 0.69 per 100HM, 0.02 per 1000 days of native fistulae utilisation, 0.00 per 1000 days of prosthetic graft utilisation and 0.39 per 1000 days of catheter utilisation. No new case of C viral hepatitis was found. Prevalence rate at the beginning of the survey was 5.3% (35 over 664). Two centers had a significantly high AISR for VAI and two centers had a significantly low AISR for VAI. One center had a significantly high AISR for bacteraemia and one center had a significantly low AISR for bacteraemia. CONCLUSIONS The first year of Dialin running demonstrates the importance of standardised surveillance method in VAI and bacteraemia surveillance but not for viral hepatitis.

Abstract
Hemodialysis is associated with a high risk of morbidity and mortality, often caused by infections. Infections account for approximately 15% of all deaths in this patient population (the second leading cause after cardiovascular events) and for about one-fifth of admissions. Approximately one-fourth of infection-related admissions are caused by dialysis-associated peritonitis or vascular access infection that may lead to such significant complications as endocarditis or death. Published studies that assessed the determinants of hemodialysis-related vascular infections reported inconsistent findings. Variations in the definitions of infection among these studies despite the existence of standard guidelines proposed by at least 3 major work groups may explain, at least in part, these inconsistencies. A comprehensive in-depth review of those studies is needed to examine the inconsistencies in the published results. We first revised the existing vascular access-related infection definitions, then conducted a narrative review of the published literature that examined predictors of vascular access-related infections, highlighting the heterogeneity in methods and findings. Better understanding of the risk factors for vascular access-related infections may inform efficacious prevention strategies and lead to early detection of infections and improved patient care.

Abstract
The increasing incidence of central venous catheter (CVC)-related infections can be ascribed to the wider indications to central venous catheterization, to the higher attention to this issue paid by clinicians and microbiologists, and to the patient population referred to hospitals, increasingly characterized by different degrees of immunosuppression and often in critical clinical conditions. This phenomenon implies a higher health care burden and higher related costs, as well as a significant attributable mortality, that varies however according to the pathogen involved. The microorganisms most frequently involved in CVC-related infections are coagulase-negative staphylococci, Staphylococcus aureus, aerobic Gram-negative bacilli, and Candida albicans. In the management of suspected or proven central venous catheter-related infections, several issues need to be addressed: the need to remove the device or the possibility of salvage, the immediate start of calculated antibiotic therapy or the possibility of waiting for results of microbiological diagnostics and proceeding to etiologically-guided therapy. The preferred conservative method is the "Antibiotic-Lock technique" (ALT), based on the endoluminal application of antibacterials at extremely high concentrations in situ for a period of time long enough to ensure bactericidal activity. On the other hand, immediate catheter removal and initiation of appropriate calculated therapy immediately after an adequate diagnostic work-up are strongly recommended in a clinical setting of severe sepsis or septic shock.

Abstract
Thirty-two outpatient hemodialysis providers in the United States voluntarily reported 3699 adverse events to the Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN) during 2006. These providers were previously enrolled in the Dialysis Surveillance Network. The pooled mean rates of hospitalization among patients with arteriovenous fistulas, grafts, permanent and temporary central venous catheters were 7.7, 9.2, 15.7, and 34.7 per 100 patient-months, respectively. For bloodstream infection the pooled mean rates were 0.5, 0.9, 4.2, and 27.1 per 100 patient-months in these groups. Among the 599 isolates reported, 461 (77%) represented access-associated blood stream infections in patients with central lines, and 138 (23%) were in patients with fistulas or grafts. The microorganisms most frequently identified were common skin contaminants (e.g., coagulase-negative staphylococci). In 2007, enrollment in NHSN opened to all providers of outpatient hemodialysis. Specific information is available at http://www.cdc.gov/ncidod/dhqp/nhsn_FAQenrollment.html.

Abstract
Catheter-related infections are a major cause of morbidity and mortality in hemodialysis (HD) patients. This study evaluated the utility of surveillance swab cultures (Ssc) of tunneled cuffed catheter (TCC) exit sites as a prediction and prevention strategy for infection. A 6-month prospective-controlled trial with 94 chronic HD patients with a TCC who received monthly Ssc and were stratified by dialysis day into topical therapy based on Ssc results (Group A) or no therapy (Group B). Outcomes were exit site infection (ESI) and catheter-associated bacteremia (CAB). The overall monthly prevalence of positive Ssc was 14.9%. There was no difference in the number of positive Ssc (17.7% vs. 11.6%, p > 0.05) or ESI (19.6% vs.16.3%, p > 0.05) between Groups A and B, respectively. Catheter-associated bacteremia was higher in Group A (17.7% vs. 4.7%, p = 0.05). There were significantly more ESI in the patients treated for a positive Ssc. In Group A, the incidence of ESI was significantly higher in those treated for a positive vs. negative Ssc (55% vs. 12%, p = 0.009) and CAB rates trended higher with positive Ssc (22.2% vs. 16.7%, p > 0.05). The strategy of treating positive surveillance cultures is not beneficial. Positive Ssc do not predict the occurrence of catheter-related infection, and treatment of these cultures may lead to increased infection rates.

Abstract
Over the last 2 decades, hemodialysis catheter use has increased. Annually, approximately 30% of patients using a central venous catheter (CVC) experience a septic or bacteremic episode and are subsequently at risk of its associated long-term complications and mortality. Because of the serious clinical and financial impact of hemodialysis catheter-related bacteremias (HCRIs), standardized, validated definitions based on the hemodialysis patient population are necessary in order to better diagnose, monitor, and report HCRI for patient quality assurance and research purposes. The pathophysiology of HCRI involves a complex interaction between a triad that consists of the host patient, the infecting microorganism, and the vehicle catheter. Although the microorganism contribution in the pathogenesis of HCRI is likely most important, certain patient and catheter-related characteristics may be more amenable to manipulation. The key to managing HCRI is on prophylaxis against the initial microorganism catheter adherence and subsequent biofilm development. General and specific prophylactic maneuvers directed at both an intravascular and extraluminal route of microorganism entry are discussed including antibiotic- and silver-impregnated catheters and dressings, subcutaneous access devices, and topical prophylaxis at the exit site. In addition to systemic antibiotic use, the 3 methods of HRCI treatment using catheter salvage, guidewire exchange, and concurrent antibiotic lock are compared. The outcome and complications of HCRI may be serious and highlight the importance of careful, continual infection surveillance. Although the use of a multidisciplinary hemodialysis infection control team is desirable, staffing education and physician feedback have been shown to improve adherence to infection control guidelines and reduce HCRI.

Abstract
BACKGROUND AND OBJECTIVE We previously demonstrated that minocycline-EDTA was efficacious at preventing catheter-related bloodstream infections (BSIs) in three patients with recurrent infections. This study compared heparin with minocycline-EDTA as flush solutions used among dialysis patients with central venous catheters, a high-risk group for catheter-related BSI. METHODS Patients were enrolled within 72 hours of catheter insertion and randomized to receive heparin or minocycline-EDTA as a flush after each dialysis session. Each syringe containing flush solution was wrapped in orange plastic to conceal the type of solution it contained. Patients were observed for evidence of infection and catheter thrombosis. After catheters were removed, cultures were performed to determine whether microbial colonization had occurred. RESULTS During a 14-month period, 60 patients were enrolled (30 in each group). The two groups had similar demographics and underlying diseases. Catheter survival at 90 days was 83% for the minocycline-EDTA group versus 66% for the heparin group (P = .07). Significant catheter colonization, a surrogate measure of catheter-related infection, was significantly more frequent in the heparin group (9 of 14 vs 1 of 11; P = .005). There was only one catheter-related bacteremia and it occurred in the heparin group. CONCLUSIONS When compared with heparin, minocycline-EDTA had a better 90-day catheter survival (P = .07) and a decreased rate of catheter colonization. This pilot study warrants a larger prospective, randomized trial.

Abstract
During a 12-month surveillance period, haemodialysis (HD) patients in southern Israel were categorised according to the type of vascular access site (VAS), i.e., arteriovenous (AV) fistula, synthetic AV graft, and cuffed or non-cuffed vascular catheters. Endpoints, expressed as cases/100 patient-months, were: incidence of hospital admission; antibiotic therapy; bloodstream infection (BSI); and VAS infection. These were compared to Centers for Disease Control (CDC) surveillance data, overall and by VAS type. In total, 2568 patient-months were analysed. The VAS distribution differed significantly from CDC data for fistulas (72% vs. 31%), grafts (12% vs. 41%), cuffed catheters (11% vs. 25%) and non-cuffed catheters (5% vs. 3%) (p < 0.0001 in all cases). Of 151 admissions, 32% resulted from infection, for which 112 antibiotic courses (22% vancomycin) were given. There were 16 BSIs, three involving resistant strains. The incidences of admission, antibiotic therapy, BSI and VAS infection were significantly lower overall, compared to CDC rates, as were most VAS-specific endpoints. These differences may be explained by VAS type distribution, although other factors may also be involved. Reporting regional or national surveillance data may allow a standardised comparison of the incidence of HD-associated infections.

Abstract
Management of hemodialysis (HD) access infection is one of the most challenging and most common problems faced by surgeons, interventional radiologists, and nephrologists. The goal to eradicate infection is often at odds with the need to maintain access. Patients on HD are immunocompromised and typically have significant comorbid conditions placing them at high risk for the occurrence of access infection. Infection is most common with central-vein catheter access, followed by prosthetic arteriovenous grafts (AVG) and is rare with autogenous fistulas. The diagnosis is usually evident on physical exam, but it is not uncommon for these patients to present with atypical symptoms and lack of clinical findings. Although Staphylococcal species are the most common organism to cause infection, early empiric antimicrobial therapy should also include coverage for Gram-negative organisms. Management of central-vein catheter infection includes removal and delayed replacement or, in patients with mild clinical symptoms, catheter exchange over a guide wire. Our management of AVG infection includes total graft excision when patients present with sepsis or the entire graft is bathed in pus, subtotal graft excision when all of the graft is removed except a small oversewn cuff of prosthetic material on an underlying patent artery, and partial graft excision when only a limited infected portion of the graft is removed and a new graft is rerouted in adjacent sterile tissue to maintain patency of the original graft. This strategy has proven to be highly successful in the management of these complicated cases.

Abstract
BACKGROUND Hemodialysis access is one of the most common vascular procedures that is performed by vascular and general surgeons. Prosthetic arteriovenous graft (AVG) infections pose potentially life-threatening septic and bleeding complications, as well as loss of dialysis access. Strategies employed to preserve some grafts, prevent morbidity in those with major infections, and maintain access are presented. METHODS Between July 1, 1995 and August 1, 2002, 1441 AVG procedures were performed at a single institution. Fifty-one (3.5%) prosthetic AVG infections in 45 patients were identified. Twenty-seven graft infections occurred at a prior incision for placement or revision of a graft. The other 24 infections were located within the body of the graft, and 14 of these were documented to be at a recent puncture site for hemodialysis access. The most common presentation (47% [24/51]) was an exposed graft or a draining sinus tract. Management included total graft excision (TGE) when patients presented with sepsis or the entire graft was bathed in pus; subtotal graft excision (SGE), when all of the graft was removed except an oversewn small cuff of prosthetic material on an underlying patent artery; and partial graft excision (PGE), when only a limited infected portion of the graft was removed and a new graft was rerouted through adjacent sterile tissue to maintain patency of the original graft. RESULTS None of the 45 patients died or developed hand ischemia. A uniformly successful outcome was achieved in all patients who were treated with TGE (13/13: 8 vein patches, 4 primary closure, 1 arterial ligation) or SGE (15/15). However, these treatments necessitated placement of a central venous catheter for temporary dialysis access and a new AVG later. All of these 28 wounds healed by secondary intention, including all 15 cases in which an oversewn cuff of prosthetic material remained. Graft patency and wound healing were achieved in 74% (17/23) of infections treated with PGE, and placement of a temporary dialysis access catheter and new AVG were avoided. The 6 failures of PGE ultimately required TGE because of nonhealing wounds, but there were no acute hemorrhagic or septic events. CONCLUSIONS Systemic sepsis caused by prosthetic AVG infections mandates TGE. SGE and PGE can be safely employed in selected patients with infected prosthetic AVGs. SGE maintains patency of the underlying artery and avoids a difficult and time-consuming dissection. PGE offers the advantage of minimizing extensive dissection of well-incorporated uninfected graft segments and allows continued dialysis access at the incorporated portion of the graft.

Abstract
Endocarditis associated with vascular access catheters for hemodialysis (HD) is a catastrophic but not widely appreciated phenomenon. Its current incidence, clinical outcome, and associated costs are not easily ascertained. Increasing use of tunneled catheters for HD access may result in a larger pool of patients at risk for endocarditis. We present two representative cases, review recent trends, and assess the current potential for additional cases.

Abstract
Patients with end-stage renal disease (ESRD) receiving hemodialysis (HD) are vulnerable to intravascular and endocardial infections. These include vascular access infections, vascular stent infections, and bacterial endocarditis. Staphylococcus aureus is the most commonly encountered microorganism in these conditions. Prolonged intravenous antibiotic therapy is often indicated in these infections. Surgical removal of the infected vascular access or stent may be required. Infective endocarditis occurs less frequently in renal transplant recipients than in patients on HD. Although bacterial endocarditis may occur, fungal endocarditis with organisms such as Aspergillus and Candida species occurs with disproportionately high frequency among renal transplant recipients because of immunosuppression. Prolonged intravenous antibiotic or antifungal therapy is indicated, and valve replacement is often necessary.

Abstract
OBJECTIVE Bloodstream infections are a major cause of morbidity and mortality in patients receiving long-term hemodialysis. We wanted to determine the incidence of hemodialysis-related bloodstream infections in Canadian centers participating in the Canadian Nosocomial Infection Surveillance Program. METHODS Prospective surveillance for hemodialysis-related bloodstream infections was performed in 11 centers during a 6-month period. Bloodstream infections were defined by published criteria. Hemodialysis denominators included the number of dialysis procedures, the number of patient-days on dialysis, and the frequencies of different types of vascular access. RESULTS There were 184 bloodstream infections in 133,158 dialysis procedures (1.4 per 1,000) and 316,953 patient-days (0.6 per 1,000). Hemodialysis access through arteriovenous (AV) fistulae was associated with the lowest risk for bloodstream infection (0.2 per 1,000 dialysis procedures). The relative risk for infection was 2.5 with AV graft access, 15.5 with cuffed and tunneled central venous catheter (CVC) access, and 22.5 with uncuffed CVC access (P < .001). There was marked variation among the 11 centers in the means of vascular access used for hemodialysis. Significant variation in infection rates was observed among the centers when controlling for types of access. CONCLUSIONS There was a hierarchy of risk of hemodialysis-related bloodstream infection according to type of vascular access. There was significant variation in the type of vascular access being used among the Canadian hemodialysis centers, and also variation in access-specific infection rates between centers.

Abstract
The objective of this study was to describe hemodialysis vascular-access related infections that occurred in hemodialysis patients over an 18-month period. The study is a prospective descriptive analysis of incidence infection rates in a hemodialysis unit in a tertiary-care medical center. Prospective surveillance for hemodialysis vascular access-related infection was performed for all patients undergoing hemodialysis from November 1999 through April 2001 at King Fahd Hospital of King Faisal University, Al-Khobar, Saudi Arabia. The total number of dialysis sessions was calculated. The type of vascular access was noted. Cultures were obtained and all infections were recorded and infection rates were calculated. There were 9627 hemodialysis sessions (5437 via permanent fistulae or grafts, 2409 via temporary central catheters, and 1781 via permanent tunneled catheters) during the 18-month study period. We identified a total of 109 infections, for a rate of 11.32/1000 dialysis sessions (ds). Of the 109, 23 involved permanent fistulae or grafts (4.23/1000 ds); 18 involved permanent-tunneled central catheter infections (10.1/1000 ds); and 68 involved temporary-catheter infections (28.23/1000 ds). There were 38 bloodstream infections (3.95/1000 ds) and 34 episodes of clinical sepsis (3.53/1000 ds). Seventy-one vascular access infections without bacteremia were identified (7.38/1000 ds), including 16 permanent-fistulae or graft infections (2.94/1000 ds), 7 permanent-tunneled central catheter infections (3.93/1000 ds), and 48 temporary-catheter infections (19.92/1000 ds). Staphylococcal organisms were responsible for 77% of the infections, with Staphylococcus epidermidis being the strain most commonly implicated. Gram-negative organisms were responsible for 23% of the infections. In conclusion, infection rates were highest in hemodialysis patients with temporary vascular access, compared with rates in those with permanent arteriovenous fistulae and synthetic grafts. Most of the bacterial organisms isolated from the vascular access sites were gram-positive cocci, with S. epidermidis accounting for 50% of the organisms. The rate of infection with gram-negative bacilli was higher than in other reports. Our greater dependence on central venous catheters, due to local factors, coupled with the immune-compromising comorbid conditions of our patients, may be contributory to the pattern of infection reported. Delays in the creation of vascular grafts for hemodialysis access should be avoided.

Abstract
BACKGROUND Hemodialysis patients have frequent infections, especially of the vascular access site, and often harbor antimicrobial-resistant pathogens. Therefore a voluntary national system was created to monitor and prevent infections in these patients. METHODS From October 1999 to May 2001, participating centers recorded the number of chronic hemodialysis outpatients that were treated (denominator). Several outcome events, including infections of the vascular access site, were monitored. Data were reported on paper forms or via an Internet-based data entry and analysis system. RESULTS Among 109 participating centers, the vascular access infection rate per 100 patient-months was 3.2 overall and varied markedly by type of vascular access: 0.56 for native arteriovenous fistulas, 1.36 for synthetic arteriovenous grafts, 8.42 for cuffed catheters, and 11.98 for noncuffed catheters. Among 76 dialysis centers reporting at least 200 patient-months of data, 11 had a significantly low and 14 a significantly high rate of vascular access infection. CONCLUSION Initial results from the first national project to monitor infections in patients undergoing hemodialysis indicate that vascular access infections were common and that risk varied substantially among different vascular access types and different dialysis centers. These results can be used for quality improvement at individual centers and to help evaluate the efficacy of specific infection control measures.
