ORBIT offers no predictive advantage over HAS-BLED and risks underestimating.
Does the ORBIT score improve prediction of major bleeding compared to the HAS-BLED score in anticoagulated atrial fibrillation patients?
The ORBIT score does not outperform the HAS-BLED score in predicting major bleeding in anticoagulated AF patients and tends to under-predict bleeding risk by categorizing more patients as low risk.
