Abstract
INTRODUCTION: Despite advances in therapy, most persons with type 1 diabetes (PwT1Ds) do not achieve treatment goals. Education is fundamental to the care of PwT1Ds treated with continuous subcutaneous insulin infusion (CSII). AIM OF THE STUDY: To evaluate PwT1Ds treated with CSII and receiving in-hospital education and to identify factors associated with treatment effectiveness. MATERIAL AND METHODS: This cross-sectional study included adults with type 1 diabetes (T1D), who received diabetes education using the proprietary Structured Diabetes Education Program, GoPump, during "Insulin Pump Weeks" in 2022-2023. Metabolic control of diabetes was evaluated. Reports from personal insulin pumps, blood glucose meters, and continuous glucose monitoring (CGM) systems were assessed. RESULTS: Data from 107 individuals with a median age of 26.7 years (Q1-Q3: 19.0-30.8) were analysed, including 65 women (60.7%). The median duration of T1D was 13 years (Q1-Q3: 10.0-18.0), and the median duration of personal insulin pump use was 8 years (Q1-Q3: 5.0-12.0). The median body mass index was 23.9 kg/m². CGM was used by 52.3% of individuals. The median time in range (TIR) was 57.0% (Q1-Q3: 45.0-69.5%), and the median glycated haemoglobin (HbA1c) level was 7.9% (Q1-Q3: 6.8-8.5%). A positive correlation was found between age and TIR (rs = 0.42, p = 0.001). The use of temporary basal rate and dual-wave and square bolus features was positively correlated with TIR (rs = 0.34, p = 0.012 and rs = 0.31, p = 0.021, respectively) and inversely with time above range > 250 mg/dl (rs = -0.37, p = 0.007 and rs = -0.27, p = 0.045, respectively). Lower HbA1c levels were observed in individuals with a higher number of daily boluses (rs = -0.33, p = 0.001). CONCLUSIONS: In the study cohort, older age, more frequent use of advanced insulin pump features, and a higher number of daily boluses were associated with better glycaemic control in adults with T1D.
