Abstract

Objective: To analyze the use of the kinetic estimated glomerular filtration rate (KeGFR) model as an early predictor of dialysis acute kidney injury (AKI). Methods: This is a literature review, where authors analyzed the use of the KeGFR model to predict dialysis AKI earlier. Results: Patients with reduced KeGFR were more likely to have more comorbidities and were more severe patients. The lower the KeGFR, the greater the risk of death. This was also observed in the need for Renal Replacement Therapy, ICU admission and hospital admission. The agreement between the severity of AKI and the worst KeGFR achieved is controversial in the literature evaluated. Conclusion: We suggest that the AKI classification systems and the KeGFR model be used together for decision making and to obtain additional information, such as severity and prognosis.
