Adoption and Use of an Online Patient Portal for Diabetes (Diabetes-STAR)

Online patient portals, which provide patients with personal information and facilitate electronic doctor-patient communication, can help patients manage chronic diseases. These systems will be most beneficial if they have broad and durable appeal. In a randomized trial, we compared a portal providing generic diabetes self-management information to one providing personalized information (Diabetes-STAR). We assessed (1) the characteristics of patient-users and (2) whether including personalized content promotes sustained use.
