Real-World Use of Do-it-Yourself Artificial Pancreas Systems in Children and Adolescents: Self-Reported Clinical Outcomes (Preprint)
BACKGROUND Patient-driven initiatives have made uptake of Do-it-Yourself Artificial Pancreas Systems (DIYAPS) increasingly popular amongst people with diabetes of all ages. Observational studies show improvements in glycemic control and quality of life amongst adults. However, there remains a lack of research examining experiences of children and adolescents with DIYAPS in everyday life and their social context. OBJECTIVE This study assesses self-reported clinical outcomes of the pediatric population using DIYAPS in real-world use. METHODS An online survey was distributed to caregivers, assessing HbA1c and Time in Range (TIR) before and after, and problems during DIYAPS use. RESULTS 209 caregivers from 21 countries responded. Children were 47.4% female with a median age of 10y; a mean diabetes duration of 5.1y ±3.9 and 10.3m ±10.0 experience with DIYAPS. Clinical outcomes improved significantly, including HbA1c (from 6.91% ±0.88 to 6.27% ±0.67; P<.001) and TIR (from 64.2% ±15.94 to 80.68% ±9.26; P<.001). CONCLUSIONS Improved glycemic outcomes were found across all pediatric age groups including adolescents and very young children. These findings are in line with clinical trial results from commercially developed closed-loop systems. CLINICALTRIAL The study was approved by the Charité ethics committee (EA2/140/18).
