Prediction of 60-Day Case Fatality in Critically Ill Patients Receiving Renal Replacement Therapy: External Validation of a Prediction Model

Abstract

The ATN prognostic model can be useful in a broad cohort of critically ill patients. Although it showed only moderate discrimination capacity when patients with elevated admission sCr were included, using a refitted model improved it, illustrating the need for continuous external validation and updating of prognostic models over time before their implementation in clinical practice.
