Test characteristics of SIRS/OD alert to predict severe sepsis and mortality
| DERIVATION PHASE B (95%CI) | VALIDATION PHASE B (95%CI) | |
|---|---|---|
| Severe Sepsis | ||
| Sensitivity | 1·0 | 0·99 |
| Specificity | 0·94 | 0·94 |
| Area under the curve | 1·0 | 0·96 |
| LR+ | 17·9 | 15·2 |
| LR− | 0 | 0·01 |
| Mortality | ||
| Sensitivity | 0·87 | 0·86 |
| Specificity | 0·82 | 0·82 |
| Area under the curve | 0·84 | 0·84 |
| LR+ | 4·8 | 4·9 |
| LR− | 0·16 | 0·16 |
LR+ = positive likelihood ratio of the SIRS/OD alert as a test; LR− = negative likelihood ratio of the SIRS/OD alert as a test.
