[PMID: 37734681 DOI: 10.1016/j.jhin.2023.08.024] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 08/29/2023] [Accepted: 08/30/2023] [Indexed: 09/23/2023]
Abstract
INTRODUCTION Patients receiving maintenance haemodialysis are at risk of catheter-related infections. Up to now, there has been no standardized surveillance tool in Germany to evaluate infection events in haemodialysis outpatients. As such, this study aimed to implement an online-based surveillance tool in outpatient dialysis facilities, and to report the first national surveillance data for haemodialysis patients in Germany from October 2019 until September 2021. METHODS Outpatient dialysis facilities reported three types of dialysis-associated infection event (DAIE): bloodstream infections, intravenous antimicrobial starts, and local access site infections. Denominator data were provided by the number of haemodialysis treatments at each facility per month. DAIE rates stratified by vascular access type were calculated. RESULTS In total, 43 outpatient dialysis facilities reported 723 DAIEs, including 63 bloodstream infections, 439 intravenous antimicrobial starts, and 221 local access site infections. The overall incidence of DAIEs was 0.51 per 1000 dialysis treatments (723/1,413,457) during the surveillance period. The overall incidence of DAIEs was 0.13 per 1000 dialysis treatments among patients with arteriovenous fistulas (AVFs; 126/990,392), 0.41 per 1000 dialysis treatments among patients with arteriovenous grafts (41/99,499), and 1.68 per 1000 dialysis treatments among patients with central venous catheters (CVCs; 535/318,757). The rate ratio of DAIEs between CVC and AVF rates was 13.2 (95% confidence interval 10.9-16.0; P<0.001). DISCUSSION These 2-year infection data represent the first standardized data of outpatient dialysis facilities in Germany. Rates of infection were highest among patients with CVCs compared with other vascular access types. This online-based surveillance tool may be helpful to identify effective targets for infection prevention measures in haemodialysis patients.

Surveillance of hemodialysis related infections: a prospective multicenter study. Sci Rep 2022; 12:22240. [PMID: 36564392 PMCID: PMC9789026 DOI: 10.1038/s41598-022-24820-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Accepted: 11/21/2022] [Indexed: 12/24/2022] Open
Abstract
As in many countries, there is neither a surveillance system nor a study to reveal the hemodialysis (HD) related infection rates in Turkey. We aimed to investigate the infection rate among HD outpatients and implement CDC's surveillance system. A multicenter prospective surveillance study is performed to investigate the infection rate among HD patients. CDC National Healthcare Safety Network (NHSN) dialysis event (DE) protocol is adopted for definitions and reporting. During April 2016-April 2018, 9 centers reported data. A total of 199 DEs reported in 10,035 patient-months, and the overall DE rate was 1.98 per 100 patient-months. Risk of blood culture positivity is found to be 17.6 times higher when hemodialysis was through a tunneled catheter than through an arteriovenous fistula. DE rate was significantly lower in patients educated about the care of their vascular access site. Staphylococcus aureus was the most causative microorganism among mortal patients. Outcomes of DEs were hospitalization (73%), loss of vascular access (18.2%), and death (7.7%). This first surveillance study revealed the baseline status of HD related infections in Turkey and showed that CDC National Healthcare Safety Network (NHSN) DE surveillance system can be easily implemented even in a high workload dialysis unit and be adopted as a nationwide DE surveillance program.

Abstract
Hemodialysis patients are vulnerable to infectious diseases and frequent receipt of antimicrobial agents. The aim of this study was to describe the prevalence and characteristics of infections and antimicrobials use among hemodialysis outpatients. We utilized the dialysis event surveillance protocol developed by the National Healthcare Safety Network to conduct a prospective multicenter study in Anhui, China. A total of 41 dialysis centers involving 7393 outpatients were included. Fistula was the most common type of vascular access (85.3%), followed by tunneled central line (12.7%), and non-tunneled central line (1.2%). There were 118 dialysis events with an overall pooled events rate of 1.60 per 100 patient-months. Intravenous antimicrobial start, positive blood culture, and pus, redness, or increased swelling at the vascular access site were detected at rates of 0.91, 0.23, and 0.46 per 100 patient-months, respectively. The prevalence of dialysis events was commonly higher in patients with a central line, and lower in patients with a fistula. Hemodialysis outpatients also had the noteworthy risks of nonaccess infections. Older age, female gender, and having a central line were associated with the increased risk of dialysis events. Findings recommend that regular monitoring and improvement strategies are warranted in management of infections among hemodialysis outpatients.

Wongmahisorn Y. Maturation of arteriovenous fistulas in patients with and without preexisting hemodialysis catheters. Ann Med Surg (Lond) 2019; 48:11-16. [PMID: 31693714 PMCID: PMC6806382 DOI: 10.1016/j.amsu.2019.10.008] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2019] [Revised: 09/30/2019] [Accepted: 10/06/2019] [Indexed: 12/13/2022] Open
Abstract
Background Central venous catheter (CVC) placement has been linked to systemic inflammation. This study was conducted to compare the successful maturation of arteriovenous fistulas (AVFs) and the preoperative white blood cell (WBC) profiles between patients with and without preexisting CVCs. Materials and methods A retrospective cohort study was conducted with 550 patients who underwent first-time AVF creation. Patients were divided into three groups according to preexisting CVCs and CVC types as follows: tunneled CVC (n = 23), nontunneled CVC (n = 223), and no CVC (n = 304). These three groups were compared in terms of AVF maturation and preoperative WBC profiles. Results The mean age of the patients was 61.1 ± 14.3 years. The AVF maturation rates of the tunneled CVC, nontunneled CVC and no CVC groups were 65.2%, 54.7% and 74.7%, respectively (p < 0.001). According to the uni- and multivariate analyses, only the nontunneled CVC group had a lower odds of AVF maturation compared to the no CVC group (adjusted odds ratio 0.43; 95% confidence interval 0.29–0.62). Patients with preexisting nontunneled CVC but not tunneled CVC also had significantly higher mean WBC and neutrophil counts but a lower percentage of lymphocytes than patients with no preexisting CVC. Conclusion Preexisting nontunneled CVC had a negative impact on the successful maturation of the newly created AVF. Patients in the nontunneled CVC group had the highest preoperative WBC and neutrophil counts but the lowest lymphocyte percentage compared to patients in the other two groups. Nontunneled CVC has a negative impact on the successful maturation of AVF. AVF maturation could be affected by duration of CVC placement. Preexisting nontunneled CVC is significantly related to high preoperative WBC count.

Abstract
Background Hepatitis C (HCV) infection is the most commonly acquired infection for patients on hemodialysis and is associated with significant morbidity and disease progression. Direct-acting antivirals (DAAs) have revolutionized the management of HCV. However, limited data exist regarding their efficacy in end-stage renal disease (ESRD), especially for patients on dialysis in South Asia. Aims To evaluate the treatment outcomes of patients undergoing hemodialysis with chronic hepatitis C (CHC) on the sofosbuvir (SOF) and daclatasvir (DAC) regimen. Materials and methods All patients who were 18 years or older, diagnosed cases of chronic kidney disease (stage V), and undergoing maintenance hemodialysis were inducted into this study. Active HCV infection was demonstrated by polymerase chain reaction (PCR) HCV ribonucleic acid (RNA) (qualitative). All patients were then treated with a double regimen of SOF (400 mg once daily) and DAC (60 mg once daily) taken per oral for 12 weeks. Response to treatment was assessed at four, 12, and 52 weeks. Results A total of 31 out of 80 patients were inducted into the study over two years. The prevalence of HCV in hemodialysis patients was 38.75%. Sustained virological response (SVR) was achieved by 27 (87.09%) patients at one year. Four (12.90%) patients had a relapse of HCV. There was no deterioration of hepatological status in any of the patients. Overall survival at one year was 93.54%. Conclusion HCV is highly prevalent in patients undergoing hemodialysis. Prompt treatment with SOF and DAC demonstrates a good response, with negligible side effects.

Three years' experience of dialysis event surveillance. Am J Infect Control 2019; 47:793-797. [PMID: 30736969 DOI: 10.1016/j.ajic.2018.12.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2018] [Revised: 12/10/2018] [Accepted: 12/10/2018] [Indexed: 11/22/2022]
Abstract
BACKGROUND The main study aim was to track infections, evaluate performance, and identify opportunities for improved practice since infections, especially those associated with multidrug-resistant organisms, are the second most common cause of death among end-stage renal disease patients. METHODS This study describes the establishment of baseline dialysis event surveillance at a large dialysis center. Every month, the dialysis center staff reported the total number of maintenance hemodialysis patients to the department of infection control and hospital epidemiology. The surveillance system for dialysis events included monthly monitoring of hemodialysis patients in outpatient settings for positive blood cultures, intravenous antimicrobial initiation, and local vascular access infections. RESULTS We calculated the pooled mean rates of positive blood cultures, intravenous antimicrobial initiation, and local vascular access infections during the period from June 1, 2014 to September 30, 2017. Results indicated more dialysis events were attributed to the CVC than any other dialysis vascular access. Regardless of vascular access type, intravenous antimicrobial initiation was the most commonly reported dialysis-associated event. CONCLUSIONS Dialysis events surveillance can be used to produce a decrease in both morbidity and mortality rates in hemodialysis patients.
