Excerpt
Acute renal failure (ARF) is common among patients with sepsis and increases mortality [
1]. However, the prognostic utility of the newly released classification for ARF, entitled RIFLE (Risk, Injury, Failure, Loss, and End-stage kidney disease) [
2], in predicting mortality in such patients has not yet been assessed. We sought to evaluate retrospectively the usefulness of RIFLE in predicting mortality in patients with sepsis admitted to the infectious disease intensive care unit (ICU) of our hospital between January 2005 and December 2006. Data were collected from the unit database. Sepsis was classified in accordance with American College of Chest Physicians and the Society of Critical Care Medicine consensus [
3]. Patients with chronic kidney disease on dialysis were excluded from the analysis. The Simplified Acute Physiology Score (SAPS) version II was calculated based on the worst variables recorded during the first 24 hours of ICU admission. Mortality was assessed at day 60 [
2]. Forward stepwise multivariate regression analysis was employed to evaluate independent predictors of mortality. The goodness-of-fit was tested by means of the Hosmer-Lemeshaw statistic. Area under the receiver operating characteristic curve (AUROC) was employed to evaluate the prognostic accuracy of RIFLE and SAPS II. A two-tailed
P < 0.05 was considered statistically significant. …
