Popis: Rivaroxaban is used increasingly as an oral anticoagulant; however, a specific reversal agent is not currently available in the Australasian setting. There is also variation across international consensus guidelines regarding advice on the management of bleeding.To review the real-world management of rivaroxaban-associated major bleeding across the public hospitals of New Zealand's largest city.A retrospective cohort analysis was performed of patients prescribed rivaroxaban who presented to four metropolitan hospital Emergency Departments between 1 August 2018 and 31 May 2021 with major bleeding as defined by the International Society on Thrombosis and Haemostasis.One hundred and twelve patients were identified, accounting for 115 major bleeding presentations. Upper gastrointestinal (34%) and intracranial (31%) bleeding sites were most common. Procedural intervention was required in 44% of patients. Haemostatic management involved tranexamic acid (TXA) in 26%, prothrombin complex concentrate (PCC) in 55% (dose range 1000-6000 IU or 10-65 IU/kg), vitamin K in 16% and fresh frozen plasma in 1%. Rivaroxaban was discontinued permanently following 56 (49%) events, switched to another anticoagulant in 24 (21%) and withheld in 30 (26%) from 2 days to 3 months (median 8.5 days). All-cause mortality at 90 days after bleeding was 17% (19 patients), and the incidence of combined venous and arterial thrombotic events was 10%.There is considerable heterogeneity in the acute clinical management of patients presenting with rivaroxaban-related major bleeding. The use of PCC and dosage administered is inconsistent. TXA was utilised in only approximately one-quarter of all cases. Evidence-based guidance for treating rivaroxaban-related bleeding would improve the management of these patients and potentially improve clinical outcomes.
