Prognostic Scores for Acute Kidney Injury in Critically Ill Patients.

Background: Numerous prognostic scores have been developed and used in intensive care; however, the applicability and effectiveness of these scores in critically ill patients with acute kidney injury may vary due to the characteristics of this population.

Objective: To assess the predictive capacity of the Simplified Acute Physiology Score III (SAPS III), Sequential Sepsis-related Organ Failure Assessment (SOFA) and Nursing Activities Score (NAS) prognostic scoring systems for acute kidney injury in critically ill patients.

Methods: Cohort, prospective and quantitative study with follow-up of 141 critical patients in intensive care.
