Methodology · worked example, guidelines & full notes
Widely used to risk-adjust bacteraemia outcomes.
When to use
Risk-adjust and prognosticate in bloodstream infection.
How it works
Temperature (0–2), hypotension (2), mechanical ventilation (2), cardiac arrest (4), mental status (0–4). ≥ 4 = high risk.
Key points
- Widely used to risk-adjust bacteraemia outcomes.
- ≥ 4 is a common severity cut-off.
- Captures acute physiology, not the organism.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Temperature | 35.0–35.9 or 38.5–38.9 (1) |
|---|---|
| Hypotension (acute, vasopressors, or SBP drop) | No |
| Mechanical ventilation | No |
| Cardiac arrest | No |
| Mental status | Disoriented (1) |
→Pitt score2
- Interpretation：Intermediate
- Note：A Pitt score ≥ 4 is a widely used cut-off for acute severity in bacteraemia studies.
| Temperature | 35.1–38.4 °C (0) |
|---|---|
| Hypotension (acute, vasopressors, or SBP drop) | No |
| Mechanical ventilation | No |
| Cardiac arrest | No |
| Mental status | Alert (0) |
→Pitt score0
- Interpretation：Lower risk
- Note：A Pitt score ≥ 4 is a widely used cut-off for acute severity in bacteraemia studies.

FAQ
Frequently asked questions
- What are the limits and cautions when using Pitt Bacteraemia Score?
- For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
- Does Pitt Bacteraemia Score upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is Pitt Bacteraemia Score calculated in practice? Can you show a worked example?
- Inputs: Temperature 35.0–35.9 or 38.5–38.9 (1), Hypotension (acute, vasopressors, or SBP drop) No, Mechanical ventilation No, Cardiac arrest No, Mental status Disoriented (1) → Result: Pitt score 2（Interpretation: Intermediate, Note: A Pitt score ≥ 4 is a widely used cut-off for acute severity in bacteraemia studies.） Inputs: Temperature 35.1–38.4 °C (0), Hypotension (acute, vasopressors, or SBP drop) No, Mechanical ventilation No, Cardiac arrest No, Mental status Alert (0) → Result: Pitt score 0（Interpretation: Lower risk, Note: A Pitt score ≥ 4 is a widely used cut-off for acute severity in bacteraemia studies.）
