impact of a digital self-management program on a1c for individuals with type 2 diabetes

Conditions: Type 2 Diabetes

Summary: the goal of this study is to evaluate a digital chronic disease self-management program designed to provide virtual support and guidance for patients with type 2 diabetes.

approximately 45% of patients with type 2 diabetes do not achieve adequate glycemic control (a1c \< 7%). when diabetes is uncontrolled, complications develop that threaten health and endanger life. this study will make an effort to address this growing health challenge and to reduce the burden of diabetes in this population. more broadly, this study will have important implications and benefits for the growing diabetes population in the u.s. study results will inform future interventions to reduce diabetes and improve outcomes. a better understanding of the efficacy of a digital chronic disease self-management program will directly benefit the participants of the program but, in the future, has the potential to more broadly benefit this population throughout the nation.
