Predicted probability of oral anticoagulant initiation by frailty and reason for hospitalization among patients with guideline-based indications for anticoagulation
a Compared with non-frail patients, those with mild frailty had a 1.8% lower predicted probability of initiating anticoagulation (CI −3.6% to −0.04%) and those with moderate-severe frailty had 6.6% lower predicted probability of anticoagulation (CI −8.9% to −4.4%).
b Compared to patients hospitalized for atrial fibrillation, those hospitalized for all other reasons had lower predicted probability of initiating anticoagulation (differences: −4.0% [CI −7.1% to −0.83%] for cardiac surgery patients, −20.8% [CI −22.2% to −19.4%] for patients with other cardiovascular conditions, −32.4% [CI −33.6 to −31.1%] for patients with non-cardiovascular conditions, and −42.6% [CI −44.2% to −40.9%] for patients with bleeding).
