Assessing patients' and caregivers' perspectives on stability of factor VIII products for haemophilia A: a web-based study in the United States and Canada.
Haemophilia A is a rare inherited bleeding disorder characterized by an inability of the blood to clot normally. Patients can experience spontaneous or trauma-induced joint and soft tissue bleeding and must keep coagulation factor VIII (FVIII) accessible at all times; thus, FVIII product storage and stability are critical. Our primary objective was to assess haemophilia A patients' and caregivers' experiences and preferences with FVIII product storage and stability. A secondary objective was to evaluate the use of the social media site Facebook in recruitment. In this cross-sectional study, 145 English-speaking adult patients and caregivers of children with haemophilia A were recruited through two state-based haemophilia organizations in the United States (US) and one national organization in Canada for a web-based survey assessing demographics and FVIII product ordering, usage, and storage practices. Of the 101 individuals who completed the survey, 60% resided in Canada; 57% were recruited through Facebook. Caregivers and patients responded similarly to questions about ordering practices and product usage, with some distinction between groups in storage practices. Two-thirds of participants noted challenges with storing FVIII products, especially storage away from home. More than half preferred storing FVIII products at room temperature vs. in the refrigerator for long periods of time. FVIII product accessibility, usage and storage affect disease management. Results support the need for more convenient and accessible FVIII products for patients in daily life and while travelling. In addition, the use of social media has potential value in recruiting this population.
