Non-typhoidal Salmonella vascular infection score
From IDWiki
Non-typhoidal Salmonella vascular infection score / (Redirected from NTSVI score)
Background
- Somewhere around 20% of patients who have bacteremia with non-typhoidal Salmonella have endovascular infection
Clinical Criteria
| Criterion | Score |
|---|---|
| Hypertension | +1 |
| Male sex | +1 |
| Serogroup C1 | +1 |
| Coronary artery disease | +1 |
| Malignancy | -1 |
| Immunosuppressive therapy | -1 |
Interpretation
| Score | Risk of Endovascular Infection | Interpretation |
|---|---|---|
| ≤0 | 2% | Low risk; no need for further imaging |
| 1 | 11% | |
| 2 | 39% | Not low risk; should get imaging to exclude endovascular infection |
| 3 | 55% | |
