IMPROVE Bleeding Risk Score
IMPROVE bleeding-risk score (Decousus 2011): weighted criteria including active ulcer (4.5), prior bleeding (4), platelets < 50 (4), banded age and renal failure, plus hepatic failure, ICU, central line,…

Example
- Active gastroduodenal ulcer
- No
- Bleeding in 3 months prior
- No
- Platelet count < 50 x10^9/L
- No
- Age category
- <40 (0)
- Hepatic failure (INR > 1.5)
- No
- Renal failure
- None / eGFR >=60 (0)
- ICU / CCU admission
- No
- Central venous catheter
- No
- Rheumatic disease
- No
- Active cancer
- No
- Male sex
- No
Result: IMPROVE-Bleeding 0: not high bleeding risk per Decousus 2011 (cutoff >=7).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- <7
- Not high bleeding risk per Decousus 2011 (cutoff >=7).
- >=7
- High bleeding risk per Decousus 2011; favor mechanical over pharmacologic prophylaxis.
What you enter
- Active gastroduodenal ulcer (4.5)
- Bleeding in 3 months prior (4)
- Platelet count < 50 x10^9/L (4)

- Hepatic failure (INR > 1.5) (2.5)
- Renal failure (none = 0, moderate = 1, severe = 2.5)
- ICU / CCU admission (2.5)
- Central venous catheter (2)
- Rheumatic disease (2)
- Active cancer (2)
- Male sex (1)
