title: Discriminatory power of the intraoperative cell salvage use in the prediction of platelet and plasma transfusion in patients undergoing cardiac surgery.
abstract: BACKGROUND
  We aim to assess the discrimination of transfused salvaged blood in predicting perioperative platelet and plasma transfusion.
  
  
  METHODS
  Retrospective review was performed on all patients undergoing cardiac surgery with cell saver (CS) support. The area under the receiver operating characteristics curve was calculated.
  
  
  RESULTS
  The discrimination achieved by transfused CS volumes in predicting perioperative platelet and plasma transfusion was poor (AUC 0.642 and 0.613 respectively). None of the covariates included (preoperative platelets, cardiopulmonary bypass use and time, aortic cross clamp time and use of aspirin or clopidogrel within 7 days of surgery) were statistically significant predictors.
  
  
  CONCLUSIONS
  Volumes of transfused CS blood have poor discrimination in predicting platelet and plasma transfusion.
