Abstract
Objective: To evaluate the effect of an employer-sponsored T2D management virtual program (Onduo) on blood glucose changes, via an independent data source, within the first year of participation. Methods: This retrospective pre-post study included participants with T2D who engaged in Onduo Dec 2020-Sept 2021. Participants had to have completed an employer-sponsored wellness program (independent of Onduo) with year-end biometric screening in 2019, 2020 and 2021, which included HbA1c, fasting glucose (FG), lipids, and other biometric measurements (Table). Year-to-year changes pre-intervention (2019 vs 2020 wellness screening, before Onduo) and post-intervention (2020 vs 2021) were compared using paired t-tests (significant at P ≤.05). We also assessed year-to-year changes based on use of specific Onduo telehealth tools (mobile app, blood glucose meter [BGM], health coach consultations, continuous glucose monitor [CGM], and telemedicine visits). Results: All 578 participants included (Table) used a mobile app, 84% used personalized coaching, 69% BGM, 13% telehealth visits, and 10% CGM. Seventy (12.1%) participants had HbA1c ≥9% in 2019, 79 (13.7%) in 2020, and 57 (9.9%) in 2021 (2019 vs 2020: P =.3; 2020 vs 2021: P =.01; Χ 2 tests). Within the first year of intervention, year-to-year changes in HbA1c, FG, HDL, and LDL significantly improved compared to pre-intervention changes (Table). The largest glycemic improvements post-intervention were in participants with baseline HbA1c ≥9% ( P <.001; ANOVA) or baseline FG ≥126 mg/dL ( P <.001; 2-sample t-test). Participants who used a CGM or telemedicine visits (n=81) had greater post-intervention drops (2020 vs 2021) in HbA1c than did others (-0.7 vs -0.2%, P <.01; 2-sample t-test). Conclusions: Participation in Onduo improved year-to-year trends in HbA1c, FG, HDL, and LDL. Improvements in glycemia were greater in participants with the highest baseline glycemic indices and those who used a CGM or telemedicine visits.
