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.

We propose to conduct a 12-month randomized controlled trial comparing usual care versus chronic disease management over the Internet among disadvantaged African-Americans with type 2 diabetes. Subjects will be recruited from patients receiving primary care at Harborview Medical Center, the County facility administered by the University of Washington in Seattle. As part of a pretest-posttest experimental design, 30 intervention subjects will be trained to use an existing diabetes disease-management module comprising six Web sites that are accessed from home via links displayed within the University's MyUW Internet portal. These sites allow patients to: 1. View their entire electronic medical record, the same record used by providers, 2. Upload blood glucose readings stored in a digital meter, 3. Enter medication, nutrition, and exercise information into an online daily diary, 4. Communicate with providers regarding treatment recommendations or other questions using clinical e-mail, 5. Obtain additional information from a traditional patient education site with endorsed content, and 6. Employ a second education site to collaboratively generate action plans intended to enhance self-efficacy. All data can be viewed by patients and providers in online trended displays that a clinical pharmacist will use to review cases no less often than weekly. As an attention control, 30 subjects will also be trained to use a provided personal computer to access Internet knowledge resources, but will not have access to the case-management services and module being evaluated. By comparing the two groups, we aim to: 1. Determine the effect of case-managed, Web-based diabetes care on glycemic control, healthcare utilization, self-efficacy, and patient satisfaction, and 2. Use semi-structured interviews among a subsample of both trial arms to qualitatively identify enablers of the successful use of computers, the Internet, and e-health applications by disadvantaged patients.
