Preoperative Geriatric Nutritional Risk Index Score as a Novel Predictor of Postoperative Acute Kidney Injury in Noncardiac Surgery: The NARA-AKI Cohort Study.

ABSTRACT:

Rationale & objective

Malnutrition could be a risk factor for postoperative acute kidney injury (AKI). The geriatric nutritional risk index (GNRI) is a simple indicator of malnutrition, and this study examined the association of preoperative GNRI with postoperative AKI in noncardiac surgery.

Study design

A retrospective cohort study.

Setting & population

Adults who underwent noncardiac surgery under general anesthesia from 2007-2011 were included. Obstetric or urologic surgery, missing serum creatinine, baseline estimated glomerular filtration rate <15 mL/min/1.73 m², and preoperative dialysis were excluded.

Predictor

Preoperative GNRI.

Outcome

AKI within 7 days after surgery.

Analytical approach

Multivariable logistic regression and re
