Background and objectivesIncreased donor age is one of the most important risk factors for delayed graft function (DGF), and previous studies suggest that the harmful effect of cold ischemia time is increased in kidneys from older donors. Our aim was to study the association of increased donor age and cold ischemia time with the risk of delayed graft function in a large cohort kidney transplants from the current era.Design, setting, participants, & measurementsThe Scientific Registry of Transplant Recipients was used for this observational, retrospective registry analysis to identify all deceased donor kidney transplantations in the United States between 2010 and September 2018, who were on dialysis pretransplantation (n=90,810). The association of donor age and cold ischemia time with the risk of DGF was analyzed in multivariable models adjusted for recipient characteristics (age, race, sex, diabetes, calculated panel-reactive antibodies, pretransplant dialysis duration) and donor characteristics (cause of death, sex, race, body mass index, creatinine, donation after circulatory death status, history of hypertension, and HLA mismatch).ResultsCold ischemia time and donor age were independently associated with the risk of DGF, but the risk of DGF was not statistically significantly lower in donor age categories between 50 and 64 years, compared with donors ≥65 years. The harmful association of cold ischemia time was not higher in kidneys from older donors in any age category, not even among donation after circulatory death donors. When donor risk was assessed with kidney donor profile index, although a statistically significant interaction with cold ischemia time was found, no practically meaningful increase in cold-ischemia susceptibility of kidneys with a high kidney donor profile index was found.ConclusionsWe were unable to demonstrate an association between donor age and DGF. The association of longer cold ischemia time with the risk of DGF was not magnified in older or more marginal donors.

The Impact

Abstract Background and Aims Delayed graft function (DGF), defined as the need for dialysis within one week post-transplantation, is associated with poorer kidney graft survival. We aimed to identify risk factors for DGF throughout 3 decades and evaluate their effect on graft survival. Method Retrospective study including 3081 kidney transplants performed at our transplantation unit between January 1st, 1989 and December 31st, 2018, split in 3 decades (1: 1989-1998; 2: 1999-2008; 3: 2009-2018). Data regarding donor and recipient demographics, time on dialysis, immunization, cold ischemia time, hemodynamic parameters and immunosuppression were collected from our prospectively maintained data base. Results Main donor, recipient and perioperative characteristics are summarized in table 1. There were clear differences in these characteristics between the decades, standing out more adverse features from both recipients and donors. Overall incidence rate of DGF was 16% (n=493): 14% in decade 1; 19.3% in decade 2 and 15% in decade 3. On univariate analysis, most studied variables included in table 1 were statistically significant as predictors of DGF. However, on multivariate analysis, we found that in the first decade the predominant risk factors for DGF were pre-transplant dialysis time and cold-ischemia time, whilst in the following decades donor characteristics, as well as recipient’s weight became more relevant (table 2). Conclusion The observed shift from donor-unrelated variables in the first decade into donor-related variables in the second and third decades as the main determinants of DGF highlights the impact of expanding donor’s acceptance criteria. Nevertheless, the increase in expanded criteria donors did not translate into poorer overall results, probable contributors being shorter cold-ischemia times and stronger immunosuppression.
