Why the study?
Does the pattern of longitudinal change in serum creatinine predict 90-day mortality in patients after major surgery?
Does the pattern of longitudinal change in serum creatinine predict 90-day mortality in patients after major surgery?
A newly developed computer algorithm can calculate the complex, nonlinear relationship between postoperative renal dysfunction severity/recovery and 90-day mortality.
Creatinine trajectory patterns may refine postoperative mortality risk assessment; leaves open whether modifying renal recovery alters outcomes.
We demonstrate the nonlinear relationship between both severity and recovery of renal dysfunction and 90-day mortality after major surgery. We have developed an easily applicable computer algorithm that calculates this complex relationship.
