Abstract

Introduction: Non-tunneled central venous catheter remains the preferred vascular access at hemodialysis initiation in developing countries despite a high burden of infection complications. The goal of this study was to determine the burden, risk factors, and microbiological spectrum of catheter-related bloodstream infections at a tertiary care center in Ethiopia.

Methods: A retrospective cross-sectional study design was applied among patients who underwent central venous catheter insertion for hemodialysis between January 2016 and June 2022 with no native arteriovenous fistula and stayed more than 48 hours. Data were collected from the patient's registration book, patient charts, and microbiology registry and analyzed using SPSS 21. Binary logistic regression was applied to assess the relationship between the independent and outcome variables. P-values less than 0.05 with AOR and 95% CI were used as statistically significant variables.

Results: In this study, 353 patients were included. The mean age was 39±17.9 years and the average duration of catheter stay was 58 ±95 days. A hundred thirty-five (38.2%) CRBSIs were documented with an incidence rate of 7.74 episodes per 1000 catheter days. The causative microorganism was predominantly gram-negatives (57.6%). Duration of a catheter (AOR: 0.3; P < 0.001), previous CVC infection (AOR: 11.9; P < 0.001), high white blood cell count (AOR: 0.31; P<0.001), urban residence (AOR: 1.92; P<0.05), and low hemoglobin levels (AOR: 2.78; P < 0.05) were independently associated with catheter-related bloodstream infections.

Conclusion: In conclusion, the incidence of catheter-related bloodstream infection among patients on hemodialysis was high with gram-negative predominance. Early fistula must be planned to reduce the duration of temporary vascular access.
