Models based on perioperative basic metabolic panel laboratory values performed well in predicting acute kidney injury at 72 hours and 14 days after cardiac surgery, researchers reported in JAMA.
The researchers created four models. The first was based on preoperative serum creatinine, the second on perioperative absolute change in serum creatinine, the third on the first two models combined and the fourth on the third model plus blood urea nitrogen, potassium, bicarbonate, sodium and albumin adjusted from time of surgery to blood draw.
The derivation cohort included 58,526 patients (median
