What to do after the bleed: resuming anticoagulation after major bleeding

Abstract

Abstract Resuming anticoagulation therapy after a potentially life-threatening bleeding complication evokes high anxiety levels among clinicians and patients trying to decide whether resuming oral anticoagulation to prevent devastating and potentially fatal thromboembolic events or discontinuing anticoagulation in hopes of reducing the risk of recurrent bleeding is best. The available evidence favors resumption of anticoagulation therapy for gastrointestinal tract bleeding and intracranial hemorrhage survivors, and it is reasonable to begin postbleeding decision making with resuming anticoagulation therapy as the default plan. After considering factors related to the index bleeding event, the underlying thromboembolic risk, and comorbid conditions, a decision to accept or modify the default plan can be made in collaboration with other care team members, the patient, and their caregivers. Although additional information is needed regarding the optimal timing of anticoagulation resumption, available evidence indicates that waiting ∼14 days may best balance the risk of recurrent bleeding, thromboembolism, and mortality after gastrointestinal tract bleeding. When to resume anticoagulation after intracranial hemorrhage is less clear, but most studies indicate that resumption within the first month of discharge is associated with better outcomes.
