This grant supports a 12-month randomized controlled trial comparing usual care versus collaborative disease management over the Internet among disadvantaged African-Americans with Type 2 diabetes. The project aims to: (1) determine the effect of case-managed, Web-based diabetes care on glycemic control, health care utilization, self-efficacy, and patient satisfaction; and (2) qualitatively identify enablers of the successful use of computers, the Internet, and e-Health applications by disadvantaged patients.
