Aims: To evaluate real‐world glycaemic outcomes in children with type 1 diabetes (T1D) commencing advanced hybrid closed loop therapy (AHCL) and to explore these outcomes based on the cohort's clinical and socioeconomic characteristics. Methods: A single‐centre, population‐based retrospective study in children commencing AHCL (Smart Guard, Control IQ, CamAPS) with minimum 70% data from two‐weeks CGM pre‐AHCL was conducted between December 2021 and June 2023 in Western Australia. CGM metrics (time in range (TIR) 3.9–10 mmol/L, time below range (TBR) < 3.9 mmol/L, glucose management indicator (GMI)) were analysed at baseline, monthly and 6 months. HbA1c at baseline and 6 months were also collected. The proportion meeting glycaemic targets of TIR > 70%, TBR < 4% and GMI < 7.0% were determined. Change in TIR from baseline to 6 months was examined by the following characteristics: %TIR, age group and Index of Relative Socioeconomic Disadvantage (IRSD) of residential postcode. Results: CGM data of 309 children, mean (SD) age 12.4 (3.2) years were analysed. Glycaemia improved from baseline to 6 months with (mean) TIR +8% (95% CI 7, 9; P ≤ 0.001), GMI −0.3% (95% CI −0.3, −0.2; P < 0.001) and (median) TBR −0.3% (95% CI −0.4, −0.1; P < 0.001). Proportion meeting glycaemic targets increased from 13.3% at baseline to 30.6% at 6 months. Improvement in TIR did not differ based on age group or IRSD Quintile. Greater increase in TIR was seen in those with lowest TIR at baseline (+20.9%, −0.2%; P < 0.001 for baseline TIR < 40%, >70%). There was a 0.27% reduction in HbA1c in 6 months (n = 116) (P < 0.001). Conclusions: AHCL improves glycaemia, irrespective of age and socioeconomic characteristics, with greatest changes seen in those with lowest baseline TIR. [ABSTRACT FROM AUTHOR]
