In this retrospective study of 1 166 patients with no previous renal insufficiency who were admitted to a postsurgical intensive care unit ICU over a 2-year period the incidence of AKI was . Multivariate analysis identified American Society of Anesthesiologists physical status Revised Cardiac Risk Index high-risk surgery and congestive heart disease as preoperative AKI risk factors. AKI was an independent risk factor for hospital mortality odds ratio 95 confidence interval to P and was associated with higher severity of illness scores Simplified Acute Physiology Score II and Acute Physiology and Chronic Health Evaluation II longer ICU length of stay higher ICU mortality increased hospital mortality and higher mortality at 6month follow up. Although the study design excluded 121 patients with significant preoperative renal insufficiency by design the relatively crude serum creatinine cut-offs used certainly permitted inclusion of numerous patients with preoperative renal impairment. Accordingly the study design failed to quantify the impact of preoperative renal impairment on risk and outcomes of perioperative AKI in noncardiac surgery and this .
