title: A Score for Predicting Acute Kidney Injury After Coronary Artery Bypass Graft Surgery in an Asian Population.
abstract: OBJECTIVE
  To develop a scoring system to predict acute kidney injury in Asian patients after coronary artery bypass grafting.
  
  
  METHODS
  A retrospective analysis of data collected in an institutional cardiac database.
  
  
  METHODS
  A tertiary academic hospital in a large metropolitan city.
  
  
  METHODS
  The study comprised 954 patients with coronary artery disease.
  
  
  METHODS
  All patients underwent coronary artery bypass surgery with cardiopulmonary bypass but did not undergo any other concomitant procedures.
  
  
  RESULTS
  The main outcome measured was acute kidney injury as defined by the Acute Kidney Injury Network criteria. The following 6 clinical variables were independent predictors of kidney injury: age>60 years, diabetes requiring insulin, estimated glomerular filtration rate<60 mL/min/1.73 m(2), ejection fraction<40%, cardiopulmonary bypass time>140 minutes, and aortic cross-clamp time>100 minutes. These variables were used to develop the Singapore Acute Kidney Injury score.
  
  
  CONCLUSIONS
  The Singapore Acute Kidney Injury score is a simple way to predict, at the time of admission to the intensive care unit, an Asian patient's risk of developing acute kidney injury after coronary artery bypass surgery.
