Many children and adolescents with type 1 diabetes (T1D) have difficulties reaching the national treatment goal for HbA1c (long-term blood sugar) which is associated with increased risk for complications. This makes it important to explore what patients and their caregivers describe important in coping with everyday life. The study has been conducted within a pediatric diabetes team in the south of Sweden. The aim was to explore how Experienced-Based Co-Design (EBCD) can be used to identify, test, and evaluate improvement efforts in order to support the family with a child with T1D.
