A comprehensive review of infection risks and management in hemodialysis access sites.

Infections at hemodialysis access sites remain a critical challenge in managing end-stage renal disease patients, significantly affecting morbidity and mortality. This comprehensive review synthesizes current knowledge on risk factors, surveillance methods, diagnostic approaches, treatment strategies, and preventive measures for these infections. Through systematic analysis of literature from major databases up to July 2024, we explore infection-related complications, pathogenic agents, and management strategies. Staphylococcus aureus emerges as a primary pathogen, with concerning increases in multidrug-resistant strains. The review emphasizes the superior safety profile of arteriovenous fistulas compared to central venous catheters, highlighting the importance of access type selection. Continuous monitoring and early detection through physical examinations and specialized tests are crucial. Diagnostic accuracy is optimized by combining clinical assessment with laboratory testing and imaging studies. Treatment strategies focus on empiric systemic antibiotic therapy, guided by local epidemiology and culture results, often necessitating catheter removal for persistent infections. Preventive measures, including strict adherence to aseptic techniques and targeted use of antimicrobial locks, are detailed. The study advocates for a multifaceted approach to infection management, emphasizing multidisciplinary collaboration and adherence to evidence-based guidelines. Promising future directions, such as novel antimicrobial surfaces and lock solutions, offer potential for further reducing infection risks. This review provides valuable insights for healthcare providers, aiming to improve long-term outcomes and quality of life for hemodialysis-dependent patients through enhanced infection control strategies.
