    Abstract

    Objective: To test Web-based care management of glycemic control using a shared electronic medical record with patients who have type 2 diabetes.

    Research Design and Methods: A trial of 83 adults with type 2 diabetes randomized to receive usual care plus Web-based care management or usual care alone between August 2002 and May 2004. All patients had a glycohemoglobin (GHb) ≥7.0%, Web access from home, and could use a computer in English.

    Research Design and Methods: Intervention patients received 12 months of Web-based care management. The Web-based program included patient access to electronic medical records, secure e-mail with providers, feedback on blood glucose readings, an educational Web site, and an interactive online diary for entering exercise, diet, and medication. Primary outcome was change in GHb.

    Results: GHb levels declined by 0.7% (95% CI: 0.2 –1.3) on average among intervention patients compared to usual care patients. Systolic blood pressure, diastolic blood pressure, total cholesterol levels Use of in-person health care services did not differ between the two groups.

    Conclusions: Care management delivered through secure patient Web communications improved glycemic control in type 2 diabetes.
