Clinical assessment of mortality risk in renal transplant candidates in Spain.

Background: Prediction of mortality in wait-listed patients for kidney transplantation (KT) has not been well elucidated. We assessed whether application of the Charlson comorbidity index (CCI) and other uremia-related comorbidities, not included in the CCI, were associated with mortality in these patients.

Methods: We included 3851 adult patients from the Andalusian Registry who were placed on the waiting list for KT during the study period (1984-2012).
