Background
- Originally developed to predict mortality with Pseudomonas aeruginosa bacteremia
- Now used more broadly for mortality from infections more generally
- A modified Pitt bacteremia score (mPBS) also exists[1]
Components
- Measured at onset of bacteremia
| Criterion | Points (original) | Points (modified) |
|---|---|---|
| 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 | 2 |
| Mechanical ventilation | 2 | 2 |
| Cardiac arrest | 4 | 4 |
| Mental status | ||
| Alert | 0 | 0 |
| Disoriented | 1 | 1 |
| Stuporous/comatose | 2 | 2 |
| Comatose | 4 | 4 |
| Dialysis | 2 | |
Interpretation
- ≥4 usually used as a cutoff for increased risk of death
| Score | Gram-negative bacteremia (28-day mortality)[2] | SAB (30-day mortality)[3] | Nonbacteremic infections (14-day mortality)[4] | Candidemia (mPBS) (30-day mortality)[1] |
|---|---|---|---|---|
| 0 | ≤1% | 8% | 5% | 14% |

| 2 | 1.5% | 15% | ||
| 3 | 2% | 40% | ||
| 4 | 3% | 47% | 40% | 37% |
