Awareness, Care, and Treatment In Obesity Management of Patients With Hemophilia (ACTION) to Inform Hemophilia Obesity Patient Empowerment (HOPE)

An online web-based cross-sectional survey in which participants will complete a distinct questionnaire for patients with hemophilia and obesity (PwHO) and/or their carers/spouses/partners, or a distinct questionnaire for healthcare professionals. Each questionnaire consists of more than 100 items including pre-coded (multiple choice) closed-ended questions, yes/no questions and rating scales. It is estimated that this one-off survey will take approximately 45-60 minutes to complete. As a cross-sectional study, there will be no treatment of patients.
