Aim: We describe the real-world utilization and outcomes associated with managing oral factor Xa inhibitor (FXai)-related major bleeds. Materials & methods: Electronic records from 45 US hospitals were queried (ICD-10-CM billing codes D68.32, T45.515x or T45.525x) to identify major bleed hospitalizations related to FXai use. Patient demographics, bleed type (intracranial hemorrhage, gastrointestinal, critical compartment, traumatic, other), FXai taken, reversal or replacement agents administered (including andexanet alfa, four-factor prothrombin complex concentrate, fresh frozen plasma, others), in-hospital mortality and length of stay were recorded. ⋯ Median length of stay was 5 days across all agents, while ICU length of stay was shorter andexanet alfa (2 days) compared with other agents (3 days). Conclusion: In-hospital mortality differed by bleed type and agents administered. Andexanet alfa was associated with the lowest rate of in-hospital mortality across all bleed types.
