Incidence, Risk Factors, Organism Types, and Outcomes of Catheter-Related Bloodstream Infections in Hemodialysis Patients

Background Patients undergoing hemodialysis for End-Stage Renal Disease (ESRD) are at risk for Hemodialysis Catheter-Related Bloodstream Infections (CRBSIs). This study evaluates the incidence, risk factors, organism types, and outcomes of CRBSI in adult patients on maintenance hemodialysis at King Faisal Hospital, Rwanda. Methods This was a prospective cohort study of adult patients with end-stage renal disease undergoing hemodialysis via central venous hemodialysis catheters at King Faisal Hospital, Rwanda. Upon receiving the IRB approval, 81 eligible patients, women, and men aged between 19 and 74, were enrolled. Restricted Mean Survival Time (RMST) analysis evaluated the risk factors for CRBSI. The statistical significance was determined using p-values, with a cut-off of 0.05. Results The incidence of CRBSI was found to be 0.78 episodes per 1,000 catheter-days. Acute hemodialysis catheter type and anemia were associated with increased risk for CRBSI, with a P-value less than 0.05. In addition, all CRBSI cases were due to bacteria, with 52.63% gram-negative and 47.37% gram-positive. Out of 19 CRBSI events, nine cases (47.37%) required hospitalization with a median duration of seven days. Approximately half of the CRBSIs required catheter removal. No metastatic infection or death was noted. Conclusion The present study demonstrated that our hemodialysis unit has an incidence of 0.78 episodes per 1,000 catheter-days. Catheter type and anemia were significantly associated with CRBSI.
