Clinical data, including demographics, comorbidities, access history, anatomic features, and post-operative ultrasound measurements at 4\u20136 and 12\u2009weeks were used to predict recurrent interventions required at 1\u2009year postoperatively. Cox proportional hazards, random survival forest, pooled logistic, and elastic net recurrent event survival prediction models were built using a combination of baseline characteristics and post-operative ultrasound measurements. A web application was created, which generates patient-specific predictions contextualized with the KDOQI guidelines.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Patients underwent an estimated 1.04 (95% CI 0.94\u20131.13) interventions in the first year. Mean (SD) age was 57 (13)\u2009years; 22% were female. Radiocephalic AVFs were created at the snuffbox (2%), wrist (74%), or proximal forearm (24%). Using baseline characteristics, the random survival forest model performed best, with an area under the receiver operating characteristic curve (AUROC) of 0.75 (95% CI 0.67\u20130.82) at 1\u2009year. The addition of ultrasound information to baseline characteristics did not substantially improve performance; however, Cox models using either 4\u20136- or 12-week post-operative ultrasound information alone had the best discrimination performance, with AUROCs of 0.77 (0.70\u20130.85) and 0.76 (0.70\u20130.83) at 1\u2009year.
