Causes and Risk Factors of Hemodialysis Catheter Infection in Dialysis Patients: A Prospective Study

Abstract

Objectives: Infectious central venous catheter (CVC) complications, including mortality and care and hospitalization costs, are still a major clinical concern. This study aimed to determine the prevalence of hemodialysis catheter infection and its risk factors among hemodialysis patients. Methods: The present research was a descriptive, prospective cross-sectional study on hemodialysis patients in Babol hospitals during 2020 - 21. The participants' demographic information and some relevant data on clinical variables (namely underlying diseases, cause of dialysis, and cause of catheter removal) and catheter-related variables (namely catheter location, frequency of catheter placement, and apparent signs of catheter site) were collected and recorded directly and systematically during surgery post-surgery. Results: One hundred and twenty-two patients with temporary double-lumen acute hemodialysis catheters for dialysis, including 56 women (45.9%), were included in this study, the mean age of whom was 58.9 ± 16.4 years. Twenty-two patients (18%) developed a catheter-induced systemic infection. There was no significant relationship between the catheter site and its removal inducing infection (P > 0.05). The frequencies of microorganisms causing catheter infection included gram-positive Staphylococcus epidermis (59%) and Staphylococcus aureus (31.8%). Moreover, there was no significant correlation between demographic variables and clinical history with systemic infection induced by catheterization. Conclusions: The rate of catheter-induced infection is relatively high among patients since sterile instructions were observed during catheterization; therefore, it is recommended to pay more attention to the care and dressing of the catheter site.

Clinical Clue and Predictive Blood Count of Hemodialysis Cathether-Related Infection: Case Series

“…(18,22,24) Despite the high rates of hypertension in patients with CRBSI, several studies reported there was no statistically significant effect of hypertension in CRBSI. (16,20) Comorbid hypertension was reported in two patients of this case series, and DM was reported in one patient.…”

“…Several studies reported more prevalent CRBSI in men than women. A study by Shoaib et al, reported 65.56% male subjects (14) , Yang et al, reported 62.07% male subjects (15) , and Nasiri et al, reported 68.18% male subjects (16) , but these differences were not statistically significant between infected and non-infected DL patients. The age of reported CRBSI also varied.…”

“…The age of reported CRBSI also varied. Wiradana et al, reported a mean age of 48.71 ± 14.77 (17) , Yang et al, reported a mean age of 49.12 ± 9.93 (15) , Nasiri et al, reported that most of the patients aged under 45 years old (16) , but the age difference was also not statistically significant between infected and non-infected DL patients. This case series reported DL infection in two men (66.7%) and one woman (33.3%) with a mean age of 44.67 ± 8.21 years.…”

Chronic kidney disease in Sri Lanka: Health systems challenges of patients on hemodialysis

“…Due to a high volume of cases and a dearth of surgical theatres, there are significant delays in the creation of AVFs. Studies indicate that the majority of patients begin dialysis treatment with temporary vascular catheters, which is regarded as a suboptimal method due to the associated inconvenience and the substantial risk of central-line-associated bloodstream infections [10,11].…”
