680-P: Effect of the FreeStyle Libre System on Diabetes Treatment for People with T2D: Results from a Retrospective Cohort Study Using Canadian Private Payer Claims Database

Introduction: Therapeutic inertia is a major contributor to people with diabetes not achieving glycemic goals. We assessed for patients with T2D the impact of using the FreeStyle Libre system (FSL) vs. blood glucose monitoring (BGM) on treatment intensification. Method: We carried out a matched retrospective cohort study using secondary private payer claims data including >30 million diabetes drug and device claims filled by over 850,000 patients with T2D >18 in Canada over 24 months. Each month, patients were classified by level of therapy progression: 1. No diabetes drug therapy; 2. Mono Oral Antihyperglycemic Agents (OHAs) ; 3. Dual OHAs; 4. Triple OHAs; 5. Quad or more OHAs; 6. Injectable GLP1-RA (±concomitant OHAs) ; 7. Basal insulin (±concomitant OHAs) ; 8. MDI insulin (±concomitant OHAs) . Results: A total of 373,871 patients met the inclusion criteria. Across all treatment cohorts, the FSL treatment groups were found to have a statistically higher probability of treatment intensification relative to BGM: Conclusion: Reimbursement of FSL for patients with T2D in Canada is associated with decreased time lag for glucose lowering therapy compared to those using BGM alone. These findings suggest that FSL data impact clinicians to facilitate earlier and more intensive therapy modifications and thus reduce treatment inertia.
