Weight loss and modeled cost savings in a digital diabetes prevention program

Background Participation in the National Diabetes Prevention Program (DPP) can improve individual health through reduced risk of type 2 diabetes and save healthcare system substantial medical costs associated with a diagnosis its complications. There is less evidence outcomes cost savings fully digital delivery DPP. Methods This study assessed 13,593 members who provided an initial weight subsequently achieved various loss engagement during their participation Analyzed data included both complete observations missing imputed using maximum likelihood estimation. Findings include members' behavioral correlates literature-based cost-savings estimate achieving three mutually exclusive or benchmarks: ≥5% loss, >2% but <5% completion ≥4 educational lessons. Results 11,976 (88%) after months participation, enabling calculation nadir. Considering data, 97% maintained lost weight. Using for these calculations, 32.0% ≥5%, 32.4% <5%, ±2%, 3.6% gained Members most nadir furthest into program (mean day = 189, SE 1.4) had longest active days 268, 1.4), particularly compared to 119, 3.7; mean 199, 4.9) (both p ≤ 0.0001). Modeled 1-year estimates ranged from $11,229,160 $12,960,875. Conclusions DPP clinical that confer important benefits savings.
