CRUSADE bleeding score (1–100 points) = sum of points from eight baseline variables measured before antithrombotic therapy or transfusion.

Predictor	Category	Points

	16–30	35
	31–60	28
	61–90	17
	91–120	7
	>120	0
Heart rate (beats/min)	≤70	0
	71–80	1
	81–90	3
	91–100	6
	101–110	8
	111–120	10
	≥121	11
Systolic BP (mmHg)	≤90	10
	91–100	8
	101–120	5
	121–180	1
	181–200	3
	≥201	5
Sex	Female	8

	Absent	0
Prior vascular disease (peripheral artery disease or prior stroke)	Present	6
	Absent	0
Diabetes mellitus	Present	6
	Absent	0

This calculator uses Cockcroft–Gault creatinine clearance in mL/min; estimated glomerular filtration rate indexed to body surface area is not equivalent for scoring.

Bleeding risk interpretation:

Score range	Risk category	Estimated in-hospital major bleeding risk
≤20 points	Very low	3.1%
21-30 points	Low	5.5%
31-40 points	Moderate	8.6%
41-50 points	High	11.9%
>50 points	Very high	19.5%
