When to use
- Estimating bleeding risk specifically in AF patients treated with a DOAC.
Formula
Age (65-69:2, 70-74:3, 75-79:4, >=80:5); CrCl 30-60:1, <30:2; underweight 1; stroke/TIA/embolism 1; diabetes 1; hypertension 1; NSAID 1; liver disease 2; prior bleeding 3; aspirin 2 or DAPT 3.
Pearls and pitfalls
- Outperformed HAS-BLED for DOAC-treated AF in the derivation cohorts.
- Bleeding rates are approximate and cohort-dependent.
