Failure of the New Kidney Allocation System in a Specific Ethnic Group
2020
Introduction: The Kidney Allocation System (KAS) implemented on December 4, 2014, was expected to improve kidney transplant list wait-time and allocate more kidney to high cPRA patients. This study aims to demonstrate outcomes after the implementation of the KAS in a Hispanic transplant center.
Methods: Retrospective study from a prospectively maintained database from a single-transplant center. Included all DDKT from July 2013 to June 2016. Compare and analyze DDKT selection and outcomes before and after KAS implementation.
Results: The overall number of kidney transplants performed during this period was 220. All of the patients were Hispanic. Included 50.5% Pre-KAS and 49.5% Post-KAS. Pre-KAS group had a significantly shorter waiting-time list than the post-KAS group, 900.05 vs 1126.75 respectively. EPTS less than 20% significantly improved in the Post-KAS group compared to the Pre-KAS group, 41.3% vs 20.9% respectively. No differences observed in KDPI, 1-year graft failure, or 1-year mortality rates.
Conclusion: This might be the first Hispanic only cohort evaluating the effects of KAS on a moderate volume kidney transplant center. The new system increased the wait-time list by approximately 25%, and it did not improve graft quality, graft failure, or mortality rates.
