An Online System to Improve Diabetes Self-Care

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00119938
Recruitment Status : Completed
First Posted : July 14, 2005
Last Update Posted : August 20, 2008

Robert Wood Johnson Foundation

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).

Condition or disease Intervention/treatment Phase
Diabetes Mellitus, Type 2 Behavioral: Access to online patient portal Not Applicable

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.
