Aims: To provide an understanding of medical care adherence factors as reported by caregivers, adolescent, and adult patients with sickle cell disease and to analyse those concerns to identify barriers and facilitators about medical care adherence. Three topics influenced medical care adherence: the disease itself, therapeutics, and the healthcare system. This study will focus on the first topic. Design: Qualitative explorative study, using semi‐structured and life‐experience interviews and manual inductive content analysis.
