Predictive performance of different scoring systems for predicting hospital mortality.
Scoring system | AUC | 95% CI | Best threshold | Specificity | Sensitivity | PPV | NPV |
APS III | 0.703 | 0.683–0.722 | 52.5 | 0.657 | 0.651 | 0.277 | 0.903 |
SOFA | 0.653 | 0.631–0.675 | 7.5 | 0.740 | 0.496 | 0.278 | 0.879 |
qSOFA | 0.553 | 0.535–0.572 | 1.5 | 0.250 | 0.832 | 0.183 | 0.881 |
OASIS | 0.664 | 0.644–0.685 | 37.5 | 0.527 | 0.716 | 0.234 | 0.902 |
APS = acute physiology score, AUC = area under the curve, CI = confidence interval, NPV = negative predictive value, OASIS = Oxford Acute Severity of Illness Score, PPV = positive predictive value, qSOFA = quick SOFA, SOFA = Sequential Organ Failure Assessment score.
