Peritoneal Dialysis Catheter-Related Infections

Abstract

Introduction: Peritoneal dialysis (PD) catheter-related infections remain a major cause of technique failure. Methods: Systematic review of 34 studies (2010–2024) evaluating exit-site infection (ESI) and tunnel infection rates, risk factors, and prevention strategies in PD patients. Results: Pooled incidence of ESI was 0.4–0.8 episodes per patient-year. Staphylococcus aureus was the most common pathogen. Topical mupirocin reduced ESI risk by 65%. Catheter exit-site direction (downward vs. lateral) showed no significant difference. Discussion: Stringent aseptic technique, daily exit-site care, and early antibiotic treatment reduce complication rates. Patient education is critical. Conclusion: Standardized protocols for exit-site care significantly lower infection rates.
