In a population of adults with newly diagnosed, early onset type 2 diabetes, this study will identify patient-, provider-, and system-level predictors of inadequate glycemic control within one year following diagnosis. A longitudinal, retrospective cohort analysis of electronic health record data will be conducted to examine associations between select factors and early glycemic control. This study will also explore barriers to and facilitators of type 2 diabetes care; patients and providers will be engaged in a qualitative process to identify barriers and facilitators affecting early diabetes care. Lastly, this project will examine associations between patient-reported factors and early glycemic control. To extend characterization of potentially modifiable care barriers in this population, validated instruments (selected based on existing literature and study findings) will be used to survey a cohort of patients and follow this cohort prospectively for one year to assess relationships between responses and glycemic control.
