Why the study?
An externally validated risk index that can be practically implemented before patients undergo noncardiac surgery to predict postoperative AKI was needed.
Does the SPARK index accurately predict the risk of postoperative AKI in patients undergoing noncardiac surgery?
Population
51,041 discovery and 39,764 validation patients without preexisting renal failure undergoing noncardiac surgery in Korea
Design
Retrospective observational prediction index development and external validation study
Follow-up
90 days after surgery

May support preoperative AKI risk stratification in noncardiac surgery; leaves open need for prospective validation and outcome trials.
Does the SPARK index accurately predict the risk of postoperative AKI in patients undergoing noncardiac surgery?
The SPARK index provides an externally validated, practical tool to stratify the risk of postoperative AKI before noncardiac surgery.
