Brief summary

The purpose of this study is to see if an online program for patients with diabetes helps patients improve their self-care (how they take their medications, what they eat, how much they exercise, and whether they smoke).

Detailed description

Patient portals are online programs that can provide a number of functions for patients, among them: * Ability to request appointments, referrals, and medication refills; * Ability to send secure electronic messages to medical staff, and to receive replies; * Access to the medical record; * Disease management We are comparing two patient portals with different sets of features to determine if personalized information and guidance can improve self-care and measures of diabetes-related health. Self-care measures will be assessed using standardized questionnaires at baseline, 3, and 6 months. Chart review will be used to assess measures of diabetes-related health.
