Revision as of 14:33, 28 July 2023
Background
- Originally developed to predict mortality with Pseudomonas aeruginosa bacteremia
- Now used more broadly for mortality from infections more generally
Components
- Measured at onset of bacteremia
| Criterion | Points |
|---|---|
| Fever (°C) | |
| ≤35 or ≥40 | 2 |
| 35.1-36.0 or 39.0-39.9 | 1 |
| 36.1-38.9 | 0 |
| Hypotension: drop by >30 SBP or >20 DBP, or vasopressors, or SBP <90 | 2 |
| Mechanical ventilation | 2 |
| Cardiac arrest | 4 |
| Mental status | |
| Alert | 0 |
| Disoriented | 2 |
| Stuporous/comatose | 4 |
Interpretation
- ≥4 usually used as a cutoff for increased risk of death
| Score | SAB (30-dy mortality)[1] | Nonbacteremic infections (14-day mortality)[2] |
|---|---|---|
| 0 | 8% | |
| 1 | 5% | |
| 2 | 15% | |
| 3 | 40% | |
| <4 | 5% | |
| ≥4 | 40% | |
| 4 | 47% | |
| 5 | 33% | |
| 6 | 43% | |
| ≥7 | 75% |
