The PREVAIL program demonstrates improved vascular access longevity in hemodialysis, indicating effective preemptive interventions.
Vascular access dysfunction remains a leading cause of morbidity in patients on maintenance hemodialysis. In response, the PREVAIL program (Preemptive Angioplasty to Improve Lifespan of Vascular Access in Hemodialysis) was established at Johns Hopkins Aramco Healthcare (JHAH) to proactively preserve arteriovenous grafts (AVGs) and fistulas (AVFs) through scheduled angioplasty and multidisciplinary care coordination.
