The aim of this study is to investigate the at-home-administration of bypassing agents for treatment of bleeding episodes in patients with congenital haemophilia with inhibitors to factors VIII and IX. We are further investigating how bleeding episodes affect the quality of life of the patient and their family or caregivers.
