Effective haemostasis was achieved in 32 of 48 (67%) bleeding patients in whom assessment was possible. Use of idarucizumab was judged inappropriate in 25 patients (28%). Idarucizumab was used in 88 patients, of whom 53 (60%) presented with severe bleeding (20 gastrointestinal and 18 intracranial) and 35 (40%) requiring urgent surgical intervention. Patients were followed for 90 days for occurrence of thromboembolism, (re-)bleeding and death. Post-reversal effectiveness was evaluated according to International Society on Thrombosis and Haemostasis (ISTH) recommendations.
