Does the Kidney Donor Profile Index (KDPI) predict graft and patient survival in a Spanish population?

Background and objective: The Kidney Donor Profile Index (KDPI), together with other donor and recipient variables, can optimise the organ allocation process. This study aims to check the feasibility of the KDPI for a Spanish population and its predictive ability of graft and patient survival. Mater...

Sumario:Background and objective: The Kidney Donor Profile Index (KDPI), together with other donor and recipient variables, can optimise the organ allocation process. This study aims to check the feasibility of the KDPI for a Spanish population and its predictive ability of graft and patient survival. Materials and methods: Data from 2734 kidney transplants carried out in Andalusia between January 2006 and December 2015 were studied. Cases were grouped by recipient age, categorised by KDPI quartile and both graft and patient survival were compared among groups. Results: The KDPI accurately discriminated optimal organs from suboptimal or marginal ones. For adult recipients (aged: 18–59 years) it presents a hazard ratio of 1.013 (P < 0.001) for death-censored graft survival and of 1.013 (P = 0.007) for patient survival. For elderly recipients (aged: 60+ years), KDPI presented a hazard ratio of 1.016 (P = 0.001) for death-censored graft survival and of 1.011 (P = 0.0007) for patient survival. A multivariate analysis identified the KDPI, donor age, donation after circulatory death, recipient age and gender as predictive factors of graft survival. Conclusions: The results obtained show that the KDPI makes it possible to relate the donor’s characteristics with the greater or lesser survival of the graft and the patient in the Spanish population. However, due to certain limitations, a new index for Spain based on Spanish or European data should be created. In this study, some predictive factors of graft survival are identified that may serve as a first step in this path.
