Serum creatinine is the most commonly used indicator of renal function, but its derivative, estimated glomerular filtration rate (eGFR), has been shown to be superior in non-surgical settings. It remains unknown if eGFR better predicts postoperative mortality in non-cardiac surgical patients. We thus tested the hypothesis that eGFR predicts 30-day mortality after non-cardiac surgery better than serum creatinine. ⋯ The eGFR is a modestly better predictor of 30-day mortality than serum creatinine in patients having inpatient non-cardiac surgery. Given that eGFR is often reported by clinical laboratories and is otherwise easy to calculate, it should generally be used in preference to creatinine alone.
