Primary Outcome Measures:
  • Change in HbA1c at 12 months [ Time Frame: 12 months ]

Secondary Outcome Measures:
  • Change in blood pressure, lipid profile and diabetes-related stress (self-report) at 12 months; cost-effectiveness analysis of the interventions. [ Time Frame: 12 months ]

Enrollment: 152
Study Start Date: February 2005
Study Completion Date: June 2010
Primary Completion Date: April 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm 1
Intervention group
Procedure: Web-based care management
Participants interact with a care manager, sending and receiving messages using an internet portal that accepts uploads from glucose and BP meters
Active Comparator: Arm 2
Procedure: Telephone and face-to-face care management
Participants interact with a care manager via face-to-face and telephone contact
Sham Comparator: Arm 3
Procedure: Internet access alone
Participants are given internet access and encouraged to seek diabetes information to help in their self management

Detailed Description:


Patients with diabetes and elevated hemoglobin A1c (HbA1c) are at risk for diabetes-related complications. Care-management may be helpful in these patients, by providing direct contact between such high-risk patients and the healthcare system. Web-based systems have previously shown promise as a means of neutralizing access barriers such as scheduling and travel to appointments and may be of particular help in improving diabetes care.


We examined the efficacy of two methods of diabetes education and care management: (1) a traditional model that involved telephone contact and face-to-face encounters (2) a web-based model with access to a diabetes care management web site. We compared these interventions to a study group that received no education or care management but was provided with a computer and access to diabetes self-management websites.


This study employed a randomized, parallel group design involving patients with diabetes mellitus and an elevated HbA1c ( 8.5%). Participants assigned to web-based care management received a notebook computer, Internet access and interacted with a care manager through a diabetes education and care management website. Participants receiving telephone-based care management interacted with a care manager using telephone and face-to-face contact. Both care management models employed medication algorithms to improve glucose and BP control. These care management groups were compared to a study group that had no care management but received a notebook computer and Internet access with their "home page" containing links to a series of diabetes self-management websites (i.e. computer only group). The primary outcome measures were HbA1c, blood pressure, and scores on the Problem Areas in Diabetes (PAID) questionnaire, each measured over 12-months.
