The CHAMP study will test the efficacy of two interventions designed to decrease uncontrolled hyperglycemia (defined as Hemoglobin-A1C (A1C) at or above 9%) among adults with diabetes. Patients from a safety-net hospital will be randomized into three groups: 1) a control group, 2) an intervention providing diabetes self-care text messages, or 3) an intervention using community health workers to provide diabetes education and linkage to care. Secondary objectives include increasing diabetes knowledge, improving diabetes self-management, and increasing use of primary care (i.e., make one visit to the physician in 6 months) among the intervention participants. A cost-effectiveness analysis will determine the most appropriate way to reduce the burden of uncontrolled diabetes.
