Abstract: Background: There is a high incidence of diabetes in West Virginia, with type 2 diabetes mellitus (T2DM) negatively correlated with income and education level in this community. More affordable interventions are needed to improve health and health equity. Purpose: The purpose of this study was to determine the impact of a game-based learning application (app) on hemoglobin A1C (HbA1c) levels over an eight to twelve-week timeframe in adults with uncontrolled T2DM. Method: The project was conducted at a local primary care clinic. Participants included 16 adults aged 18 and older diagnosed with T2DM with a HbA1C of 8% or above. Participants were instructed to complete all educational sections within the application over 4 weeks which took approximately 2 hours total to complete. A baseline and endpoint HbA1c level was obtained for each participant. Results: Baseline and endpoint HbA1c levels were compared. There was a significant reduction in HbA1c levels among participants who completed the gamification app (p=.011). Keywords: Clinic, baseline, Diabetes, endpoint, gamification, hemoglobin A1c.
