Context:  A predictive index for renal replacement therapy (RRT; hemodialysis or continuous venovenous hemodiafiltration) after cardiac surgery may improve clinical decision making and research design.

Objective:  To develop a predictive index for RRT using preoperative information.

Design, Setting, and Patients:  Retrospective cohort of 20 131 cardiac surgery patients at 2 hospitals in Ontario, Canada. The derivation cohort consisted of 10 751 patients at Toronto General Hospital (1999-2004). The validation cohorts consisted of 2566 patients at Toronto General Hospital (2004-2005) and 6814 patients at Ottawa Heart Institute (1999-2003).

Main Outcome Measure:  Postoperative RRT.

Results:  RRT rates in the derivation, Toronto validation, and Ottawa validation . . . [Full Text of this Article]
