Background: In 2014, the Organ Procurement and Transplantation Network (OPTN) approved a new kidney allocation system (KAS). One of the intended goals of this system was to allocate the top 20% of the kidneys to the younger recipients with longer life expectancy. While achieving the expected goals the new unexpected consequences arise.
Methods: Analyses of OPTN data of patients undergoing primary deceased kidney transplantation in two time periods: prior to KAS (1/2005 to 12/2014) and post KAS (12/ 2014 to 3/ 2016) was performed.
Results: A total of 115, 744 deceased kidney transplants were analyzed. The distribution of PHS high-risk kidney transplants performed in various age groups changed significantly before and after KAS implementation with increasing number of younger individuals receiving high-risk kidneys (in age group 20-29, 7% vs. 10% and in age group 30-39, 13% vs. 18% in pre- and post-KAS, respectively; p<0.0001). Conclusion: The new KAS resulted in a substantial rise in allocation of PHS increased-risk kidneys to candidates in a younger age group. Because these kidneys are still considered suboptimal further investigation of high-risk donor organ acceptance patterns by the younger individuals in the new era of KAS is needed so that its intended goals are fully realized.
