Chronic kidney disease rather than illness severity predicts medium- to long-term mortality and renal outcome after acute kidney injury

BackgroundAcute kidney injury (AKI) requiring renal replacement therapy (RRT) continues to be associated with a hospital mortality of ∼50%. Longer-term outcomes have been less well studied. We sought to determine the influence of ventilation and of underlying chronic kidney disease (CKD) on medium and longterm mortality and renal outcomes.
