We hypothesized that variations in management of transplant chronic kidney disease stage 5 leading to kidney allograft failure (KAF) and RTD, such as access, nutrition, timing of dialysis, and anemia management predict long-term survival. <b><i>Methods:</i></b> We used an incident cohort of patients from the United States Renal Data System who initiated hemodialysis between January 1, 2003 and December 31, 2008, after KAF. We used Cox regression analysis for statistical associations, with mortality as the primary outcome. <b><i>Results:</i></b> We identified 5,077 RTD patients and followed them for a mean of 30.9 ± 22.6 months. Adjusting for all possible confounders at the time of RTD, the adjusted hazards ratio (AHR) for death was increased with lack of arteriovenous fistula at initiation of dialysis (AHR 1.22, 95% CI 1.02-1.46, <i>p</i> = 0.03), albumin <3.5 g/dL (AHR 1.33, 95% CI 1.18-1.49, <i>p</i> = 0.0001), and being underweight (AHR 1.30, 95% CI 1.07-1.58, <i>p</i> = 0.006). Hemoglobin <10 g/dL (AHR 0.96, 95% CI 0.86-1.06, <i>p</i> = 0.46), type of insurance, and zip code-based median household income were not associated with higher mortality. Glomerular filtration rate <10 mL/min/1.73 m<sup>2</sup> at time of dialysis initiation (AHR 0.83, 95% CI 0.75-0.93, <i>p</i> = 0.001) was associated with reduction in mortality. <b><i>Conclusions:</i></b> Excess mortality risk observed in patients starting dialysis after KAF is multifactorial, including nutritional issues and vascular access. Adequate preparation of patients with failing kidney transplants prior to resuming dialysis may improve outcomes.</p>
