Brief summary
The goal of this randomized clinical trial is to evaluate the impact of an expert opinion during the management of patients with severe bleeding on oral anticoagulants. The main question it aims to answer is : • Does an expert help of decision during the management of patients with severe bleeding is superior to classic management ? The centers will be randomized in one of the two groups : control group and interventional group. Patients will be followed for 3 months. At their inclusion they will be managed in conformity of the randomisation of their center. They will be followed at hour 0 + 6 , H0+24 and at the end of hospitalization. After 3 months, they will be called to assess the occurrence of thrombotic events ou hemorrhage complications. Researchers will compare the classic management versus the management with an expert opinion to see if the expert opinion is superior to classic management.
