Purpose Despite the prevalent use of insulin pump therapy worldwide, few studies have been conducted among young patients with type 1 diabetes (T1D) in Korea. We investigated the durability and effectiveness of insulin pump therapy among Korean pediatric and young adult patients with T1D. Methods This study included 54 patients with T1D diagnosed at pediatric ages (range, 1.1–14.1 years) who initiated insulin pump therapy during 2016–2019 at Seoul National University Children's Hospital and Seoul National University Bundang Hospital. Clinical and biochemical data, including anthropometric measurements, insulin dose, and glycated hemoglobin (HbA1c) levels were obtained from T1D diagnosis to last follow-up. Results Forty-four patients (81.5%) continued insulin pump therapy with a median pump use duration of 2.9 years (range, 0.2–3.5 years); 10 discontinued the therapy within 12 months (<1 month, n=6; 1–6 months, n=1; and 6–12 months, n=3) due to physical interferences or financial problems. Older age (≥10 years of age) and longer diabetes duration (≥2 years) at the initiation of pump therapy were associated with discontinuation (P<0.05 for both). For patients continuing pump therapy, HbA1c levels significantly decreased after 1 year of therapy (from 8.9% to 8.1%, P<0.001) without changes in the body mass index z-scores or insulin dose. Although 4 patients experienced diabetic ketoacidosis, all recovered without complications. Conclusions Insulin pump therapy was effective in improving glycemic control in T1D patients during 12 months of treatment. Early initiation of insulin pump therapy after T1D diagnosis was helpful for continuing therapy.
