Currently some calculators estimate the risk of progression of chronic kidney disease (CKD). The 4- and 8-variable KFRE estimates the probability of requiring renal replacement therapy (RRT) within 2 to 5 years in patients with CKD stages 3 to 5. The KFRE has been validated in more than 30 countries, but not yet individually in Latin America. The KFRE allows the definition of diagnostic and therapeutic strategies, the timely planning of the initiation of RRT, and the standardized analysis of the quality of the programs, adapted to the case mix and to an external comparator.
