This study has been completed.
Information provided by:
Robert Wood Johnson Foundation Identifier:
First received: July 6, 2005
Last updated: August 19, 2008
Last verified: July 2007
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).

Condition Intervention
Diabetes Mellitus, Type 2 Behavioral: Access to online patient portal

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Single
Official Title: D-STAR (Diabetes-System To Access Records): An Online Patient Portal to Improve and Sustain Diabetes Self-Care

Further study details as provided by Robert Wood Johnson Foundation:

Primary Outcome Measures:
  • Composite measure of diabetes self-care activities, developed from the Summary of Diabetes Self-Care Measure [ Time Frame: Surveys at baseline, 3 months, and 6 months ]

Secondary Outcome Measures:
  • Qualitative assessment of the program by patients and medical staff [ Time Frame: Interviews after 9 months of deployment ]
  • Biological markers of diabetes care (hemoglobin A1c, blood pressure, LDL cholesterol) [ Time Frame: Incidentally obtained over 9 months of care ]

Enrollment: 331
Study Start Date: September 2004
Study Completion Date: December 2006
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.
