Insufficient blood flow in the arteriovenous fistulas of patients undergoing hemodialysis negatively influences the dialysis' efficiency, leading to increased puncture frequency, prolonged sessions, and elevated hospitalization and mortality rates. Key factors contributing to this suboptimal blood flow include inadequate patient performance in grip exercises, insufficient muscle strength, inadequate caregiver support during exercises, improper use of far-infrared devices during dialysis, and lack of standardized blood flow monitoring. To address these concerns, a multifaceted intervention was implemented that included promoting hand exercises, comprehensive muscle training, home-based check-in activities, proper use of far-infrared instruments, establishment of care standards, and interdisciplinary discussions on blood flow management. The intervention resulted in the proportion of patients achieving the target blood flow of 600 ml/min increasing from 78.4% to 87.2%, surpassing the project's target of 86.2%. Thus, the measures not only enhance blood flow in arteriovenous fistulas but also establish a standardized care model for vascular access in hemodialysis.
