title: [Evaluation of MODS score system and its modified system for the postoperative patients with cardiac surgery].
abstract: OBJECTIVE
  To establish a feasible postoperative score system for cardiac surgery patients.
  
  
  METHODS
  A prospective study was assigned of the 1 935 consecutive patients entering a single cardiac postoperative intensive care unit of Anzhen Hospital between Octorber, 2007 and January, 2008. Mutiple organ dysfunction score (MODS score) and modified mutiple organ dysfunction score (modified MODS score) were calculated daily at least three days, or until intensive care discharge or death. MODS score and modified MODS score of the first day, maximum MODS and modified MODS scores during the first 3 days, and maximal MODS and modified MODS scores, MODS score and modified MODS score changes between the first and the third postoperative day were calculated, then the sensitivity and specificity of the two score systems were compared by the receiver operating characteristic curve (ROC).
  
  
  RESULTS
  ROC of the operative day score: MODS was 0.742, and modified MODS was 0.810; ROC of the maximum score: MODS was 0.896, and modified MODS was 0.901; ROC of the maximum scores during the first three: MODS was 0.886, and modified MODS was 0.896; ROC of the change between the third day and the first day score: MODS was 0.777, and modified MODS was 0.808.
  
  
  CONCLUSIONS
  Both MODS score system and modified MODS score system are feasible to evaluate the patient's prognosis after cardiac surgery, and the sensitivity and specificity of modified MODS score system are better than those of MODS score system.
