Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The primary objective is to assess the health-related quality of life in subjects treated with ReFacto AF routine prophylaxis at baseline and after 6 and 12 months.
The secondary objectives are:
* To assess the subjective physical functioning of subjects treated with ReFacto AF routine prophylaxis at baseline and after 6 and 12 months;
* To assess the treatment satisfaction of caregivers of children and subjects above 18 years treated with ReFacto AF routine prophylaxis at baseline and after 6 and 12 months;
* To determine in routine clinical practice the mean annualized bleeding rate (ABR) in subjects treated with ReFacto AF routine prophylaxis;
* To describe the status of joint health measured by HJHS before and after starting routine prophylaxis for subjects above 18 years.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Age:
* From 2 to 18 years;
* Subjects above 18 years who began routine prophylaxis treatment in childhood (and were part of the national prophylaxis program when turned 18 years).
3. Previously treated patients (PTPs) with hemophilia A. Previously treated patient (PTP) is considered in this study as a subject who has at least 50 exposure days to any FVIII product. An exposure day (ED) is a 24-hour period during which a dose of FVIII concentrate has been administered, irrespective of size and frequency.
4. No history and no current FVIII inhibitor defined as a titer ≥0.6 BU/mL or any measured Bethesda inhibitor titer greater than the upper limit of normal for the laboratory performing the assay.
5. Subjects who are scheduled by their treating physician to initiate prophylaxis with ReFacto AF or to continue previously initiated prophylaxis with ReFacto AF, and subjects who are switching from prophylaxis with another FVIII product to ReFacto AF.
6. Evidence of a personally signed and dated informed consent and assent (for children 6-17 years of age) document indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of the study.
Exclusion Criteria
2. Subject has known allergic reaction to hamster proteins.
3. Presence of any bleeding disorder in addition to hemophilia A.
4. Treatment with any investigational agent or device within the past 30 days.
5. Any other contraindications according to Summary of Product Characteristics (SPC).
6. Unsuitable to participate in study for any other reason as assessed by the investigator.
7. Subjects (or a legally acceptable representative) not able to understand study documents and study procedure.
