SACrA score to predict the initiation of renal replacement therapy in critically ill patients: a single-center retrospective study.

Background: Acute kidney injury (AKI) is a prevalent complication in critically ill patients that affects the timing of renal replacement therapy (RRT) initiation. This study aimed to develop and validate the SACrA score for predicting non-emergent initiations (BUN ≥112 mg/dL or oliguria for >72 h) of RRT in critically ill patients.

Methods: We conducted a retrospective cohort study using data from two cohorts.
