1923-LB: FRONTIER—Flash Glucose Monitoring System Use in Ontario among Patients with DM in the ICES Database—Evidence from Real-World Practice

Introduction 66 or ≥ 66 years who had a first flash glucose monitoring claim between 16 Sep 2019 and 10 Apr 2021 (index date) and remained active on flash glucose monitoring for 24 months’ follow-up after the index date. ED visits and hospitalization were measured for 12 months before the index date and the last 12 months of follow-up. HbA1c data were taken from the last tests in each period. Results: Mean HbA1c was significantly improved in both age cohorts (both p .0001; Table); reductions were seen for both T1DM and T2DM, regardless of treatment used. Mean ED visits and hospitalization rates (overall, for DKA, and for hypoglycemia) improved significantly in both age cohorts, with no change in mean resource intensity weight. Conclusions: HbA1c levels and HCRU were reduced 12-24 months after sensor-based technology initiation in patients with DM. Disclosure S.B. Harris: Consultant; Abbott.
