BackgroundA high incidence of delayed graft function (DGF) after deceased donor kidney transplantation occurs in Brazil. The reasons for such have not been adequately studied.MethodsWe performed a retrospective cohort study of 346 kidney transplant recipients from deceased donors. DGF risk factors related to the recipient, donor, and transplantation surgery were analyzed and correlated with graft outcomes. A logistic regression analysis was used to identify independent risk factors and patient and graft survival were assessed using Kaplan-Meier curves.ResultsThe incidence of DGF was 70.8% (245 cases). Our final model of multivariate analysis showed that DGF is associated (P < .05) with donor final serum creatinine (relative risk [RR], 1.84; 95% confidence interval [CI], 1.26-2.70), donor age (RR, 1.02 [1.0-1.033]), receiving a kidney from national offer (RR, 2.44 [1.06-5.59]), and need for antibody induction (RR, 2.87 [1.33-6.18]). Outcomes that were associated with DGF were longer length of hospital stay (32.5 ± 20.5 vs 18.8 ± 16.3 days; P = .01), higher incidence of acute rejection (37.8 vs 12.9%; P < .01), worse graft survival at 1 year (83.5% vs 93.9%; P < .01), and higher levels of serum creatinine at 3, 6, and 12 months (P < .05). There was no difference in patient survival and the occurrence of acute rejection did not influence the survival of patients or grafts.ConclusionDGF was associated with higher donor final serum creatinine, donor age, receiving a kidney from the national supply, and need for antibody induction. Most importantly, DGF was associated with worse outcomes.Copyright © 2014 Elsevier Inc. All rights reserved.
