The main purpose of this study is to evaluate the risk of postoperative mortality and complications in surgical populations with preoperative renal insufficiency.
This retrospective cohort study use the National Surgical Quality Improvement Program (NSQIP) database to evaluate the risk of postoperative morbidity and mortality in the surgical population. Patients with estimated. glomerular filtration rate(GFR) \< 60 ml/min per 1.73 square meter are defined as the renal insufficiency group. Patients with estimated GFR \> 90 ml/min per 1.73 square meter are defined as patients without renal insufficiency. Propensity score-matching methods and multivariate logistic regression are used to calculate the risk of postoperative morbidity and mortality.
