Probabilities, Associated Calculations, and Cross-Classifications for Testing Across Modified Early Warning Scores (MEWS) in Patients With Unplanned Escalation of Care
| MEWS | Probability for Mortality, % | 1–Specificity, % | Sensitivity, % | Sensitivity – (1–Specificity), % | True Positive, n | True Negative, n | False Positive, n | False Negative, n |
|---|---|---|---|---|---|---|---|---|
| 8 | 56.8 | 0.5 | 1.3 | 0.8 | 1 | 185 | 1 | 76 |
| 7 | 51.5 | 1.6 | 5.2 | 3.6 | 4 | 183 | 3 | 73 |
| 6 | 46.0 | 3.8 | 9.1 | 5.3 | 7 | 179 | 7 | 70 |
| 5 | 40.7 | 8.6 | 11.7 | 3.1 | 9 | 170 | 16 | 68 |
| 4 | 35.6 | 25.3 | 29.9 | 4.6 | 23 | 139 | 47 | 54 |
| 3 | 30.8 | 39.3 | 57.1 | 17.8* | 44 | 113 | 73 | 33 |
| 2 | 26.3 | 64.5 | 81.8 | 17.3 | 63 | 66 | 120 | 14 |
| 1 | 22.3 | 97.9 | 100 | 2.1 | 77 | 4 | 182 | 0 |
| 0 | 18.8 | 100 | 100 | 0.0 | 77 | 0 | 186 | 0 |
Note: A cut-point of 3 was calculated in this model based upon the highest percentile value in the Sensitivity – (1–Specificity) column.
