Supplementary Material for: Design of a Self-Management Program for Children Aged 6-12 Years with Type 1 Diabetes Mellitus at the Community Hospital Herdecke, Germany

<strong><em>Background:</em></strong> Children with type 1 diabetes mellitus (T1DM) must replace lacking endogenous insulin by daily insulin injections or insulin pumps. Standards of treatment include educational programs enabling self-management. The program ‘Herdecker Kids with Diabetes' (HeKiDi) is based on an anthroposophic understanding of the human being and intends to provide an individualized, patient-oriented approach to developing diabetes-related and comprehensive human competencies. <b><i>Aim:</i></b> Analysis of the HeKiDi program for children (6-12 years) with T1DM as the first part of an evaluation of a complex intervention. <b><i>Methods:</i></b> Ethnographic approach, following the Consolidated Criteria for Reporting Qualitative Research (COREQ), including field observations and interviews with responsible persons, content analysis of materials for determining the structure and the curriculum, presented according to the Template for Intervention Description and Replication (TIDieR). <b><i>Results:</i></b> The curriculum follows the standard but adds a learning circle between the child and the therapeutic team comprising 3 stages: (1) perception of the abilities and needs of the individual child supported by adult mentors themselves suffering from T1DM, (2) reflection within the therapeutic team, and (3) daily feedback to the child. <b><i>Curricular Learning Objectives:</i></b> Children feel recognized and supported in their individual developmental and diabetes-related competencies and develop motoric, artistic, communicative, and social skills to strengthen their self-efficacy and to understand T1DM as a lifelong awareness process. <b><i>Conclusions:</i></b> The curriculum including its associated learning goals and methods was presented. The program was explained and shown to be reproducible. Whether this program truly leads to better outcomes in regard to self-efficacy and hemoglobin A1c (HbA1c, glycated hemoglobin) and how parents and children perceive this will have to be assessed using a comparative interventional study.
