DENOVA Score (Echo Need in E. faecalis Bacteremia)
DENOVA score (Berge 2019): in Enterococcus faecalis bacteremia — symptom duration ≥ 7 days, embolization, ≥ 2 positive cultures, unknown origin, valve disease, and murmur (0–6); ≥ 3 warrants echocardiography.

Example
- Duration of symptoms ≥ 7 days
- Yes
- Embolization
- No
- ≥ 2 positive cultures
- Yes
- Origin of infection unknown
- No
- Valve disease
- No
- Auscultated murmur
- Yes
Result: DENOVA score 3 — echocardiography recommended (>= 3).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- <= 2
- Echocardiography can be omitted.
- >= 3
- Echocardiography recommended. Duration, embolization, >= 2 cultures, origin unknown, valve disease, murmur. A decision rule, not an imaging order.
What you enter
- Duration of symptoms ≥ 7 days (+1)
- Embolization (+1)
- ≥ 2 positive cultures (+1)
- Origin of infection unknown (+1)
- Valve disease (+1)
- Auscultated murmur (+1)
