Introduction and Objective: Older adults on insulin have high risk of diabetes and cardiovascular (CVD) complications, yet the health economic value of geriatric-tailored continuous glucose monitoring (CGM) education is poorly characterized. We projected 10-year clinical outcomes, costs, and quality-adjusted life years (QALY) associated with REST study-informed A1c improvement. Methods: The REST study enrolled adults ≥65 years on insulin (type 1 (T1D) or type 2 diabetes (T2D) ) and either CGM naive or CGM users not meeting glycemic targets (TIR 40% and/or hypoglycemia 4%). The intervention combined remote CGM education with geriatric principles, including individualized glycemic goals and insulin regimen simplification based on CGM patterns. We used the CDC/RTI discrete-time diabetes microsimulation model (risk-equation-based projections of complications, costs, and QALYs), using the data from REST, and compared a REST-informed scenario vs usual care by applying an adjusted mean A1c reduction of 0. 49% over 6 months. Simulations were run separately for T1D and T2D. Ten-year outcomes included total medical costs, QALYs, mortality, and diabetes/CVD complications. Results: Over 10 years (mean modeled follow-up 7. 5 years), the model projected lower complication risk and mortality in REST vs. usual care. For T1D, projected reductions included MACE −2. 54%, ESRD −6. 53%, proliferative diabetic retinopathy −17. 4%, amputation −12. 8%, and mortality −2. 85%. For T2D, projected reductions included stroke −2. 52%, MI −2. 76%, revascularization −2. 83%, dialysis −5. 01%, and mortality −2. 17%. QALYs increased by +0. 075 in T1D and +0. 040 in T2D, with small increases in modeled medical costs (+87 and +71). With a 1, 000 program cost assumption, implied cost per QALY was 14, 493 for T1D and 26, 775 for T2D. Conclusion: REST-informed projections indicate lower diabetes/CVD complications and better quality-adjusted survival over 10 years, with minimal added cost, supporting this scalable remote education for older adults on insulin.
