total score =
= SUM(points for all 5 parameters)
Interpretation:
• minimum score: 0
• maximum score: 16
• The higher the score the greater the risk of a major complication.
• A score > 8 was used to identify a patient at risk for major complications within 30 days.
Performance:
• The area under the ROC curve was 0.81.
• For a cutoff of > 8, the sensitivity was 0.79 and specificity 0.73.
• For a cutoff of > 8, the negative predictive value was 94% and positive predictive value was 40%.
