Revision as of 17:16, 27 September 2024
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 exists1
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)[1] | Nonbacteremic infections (14-day mortality)3 | Candidemia (mPBS) (30-day mortality)1 |
|---|---|---|---|---|
| 0 | ≤1% | 8% | 5% | 14% |
| 1 | 1% | 5% | ||
| 2 | 1.5% | 15% | ||
| 3 | 2% | 40% | ||
| 4 | 3% | 47% | 40% | 37% |
| 5 | 5% | 33% | ||
| 6 | 7% | 43% | ||
| 7 | 10% | 75% | ||
| 8 | 14% | 69% | ||
| 9 | 20% | |||
| ≥10 | 27-81% |
