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. A modified variant of EBCD based on focus groups, workshops, and interviews with stakeholders was used. The improvement proposal parental coaching was tested and was appreciated by the participants. The qualitative content analysis of the interviews showed that the coaching program contributed to better confidence and self-efficacy. Both coaches and coachees described that the coaching contributed to better competence and a feeling of hope after attending the coach program. Experienced-Based Co-Design gave an opportunity to explore what?s important to improve, based on experiences and needs of several stakeholders.
