| Abstract |
Background: From our pilot study in 34 patients, the modified sequential organ failure assessment (SOFA) score could intra-operatively predict a prolonged ICU stay but it comprised only 4 risk factors. Our objective was to develop a practicable intra-operative model with more relevant risk factors for predicting prolonged ICU stay.
Methods: From an extensive literature review, other 6 intra-operative risk factors affecting prolonged ICU stay were identified. Another 168 patients were then recruited from whom all 10 risk factors were extracted and analysed by logistic regression to form the new prognostic model.
Results: The logistic regression analysis revealed only 6 significant risk factors integrating in the multivariate logistic regression model: age ≥60 years, P/F ratio ≤200 mmHg, platelet count ≤120,000 /mm3, requirement for inotrope/vasopressor ≥2 drugs, serum potassium ≤3.2 mEq/L, and atrial fibrillation grading ≥2. This model was then simplified into the Open-Heart Intra-operative Risk (OHIR) score, comprising the same 6 risk factors with total score = 7: a score of ≥3 indicates a likely prolonged ICU stay (AUC for ROC of 0.746).
Conclusions: We developed a new, easy to calculate OHIR scoring system for predicting prolonged ICU stay as early as 3 hours after CPB. It comprises 6 risk factors, of which 5 are manipulatable intra-operatively. |
