Hemophilia A is an X-linked coagulopathy, where there is a deficit in the production of the coagulation factor VIII. Even though there is a higher incidence of hemophilia A than of hemophilia B, it is still considered a rare disease, as its incidence is of 1 in 10,000 people born. We have applied three questionnaires regarding quality of life: Haem-A-QoL, Haemo-SYM and EQ-5D-5L to 101 adult patients with hemophilia A, which were separated into two groups: on-demand and prophylactic treatment. The results showed a relatively young lot, with medium and high education, but with a sedentary lifestyle and are pensioners. They also seem to have moderate mobility issues but, overall, a good quality of life. The quality of life in our studied lot is relatively good, but a more diverse lot is advised.
