RESUMEN
OBJECTIVE: In the Cayman Islands, a vascular access service was created in 2005 to facilitate the creation of vascular access for hemodialysis by local surgeons. The present retrospective audit aims to establish the outcomes of this practice in the Cayman Islands. METHODS: Data from the operative log of the Cayman Islands Hospital was collected over a period of 36 months. The data were analyzed using SPSS version 12.0 (SPSS Inc, USA). Statistical analyses were performed using Student's t tests and Fisher's exact tests. RESULTS: A total of 19 operative procedures were performed to create vascular accesses in 12 men and seven women. Thirteen procedures (68%) created autogenous arteriovenous fistulas (AVFs) and six (32%) involved the insertion of a prosthetic arteriovenous graft (AVG). There were six incident dialysis patients, all of whom had an AVF created. The remaining 13 prevalent dialysis patients had new accesses in the form of AVFs (n=7) or AVGs (n=6). The statistical analyses were limited by sample size, but with AVFs, there were trends toward reduced incidence of secondary failure (four of 13 versus four of six), thrombosis (four of 13 versus two of six), infectious morbidity (zero versus two of six) and less demand for interventions to maintain patency (one of 13 versus two of six) with AVFs. There were also trends toward superior primary (461 days versus 227 days) and secondary (803 days versus 205 days) patency rates for AVFs. CONCLUSIONS: In this setting, the rate of AVF creation exceeds the goals set by the National Kidney Foundation Kidney Disease Outcomes Quality Initiative and the Fistula First Breakthrough Initiative. To ensure continued delivery of modern quality care, further audits of the local practice will be required at regular intervals.
