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 35.1-36.0 or 39.0-39.9 36.1-38.9 |
2
1 0 |
| Hypotension: drop by >30 SBP or >20 DBP, or vasopressors, or SBP <90 | 2 |
| Mechanical ventilation | 2 |
| Cardiac arrest | 4 |
| Mental status
Alert Disoriented Stuporous Comatose |
0
1 2 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] | |
