BOSTON – Online diabetes management programs may lead to improved patient knowledge, engagement and accountability, as well as better communication between patient and doctor, according to a new study by the Center for Connected Health, a division of Partners HealthCare.

 Based on the results of the pilot study, which examined a program called Diabetes Connected Health, the Center for Connected Health has initiated a randomized clinical trial involving 200 patients from six primary care practices affiliated with either Massachusetts General Hospital or Brigham and Women's Hospital.

 "This study provided valuable feedback from diabetes patients and providers on the utility, benefits and limitations of a Web-based diabetes management program," said Joseph C. Kvedar, MD, director of the Center for Connected Health. "Although the mean number of readings sent per month decreased over time, the number of comments posted per month increased, indicating ongoing engagement."

 The pilot study included seven patients with type 2 diabetes at Massachusetts General Hospital. Study participants received access to a secure Web site that stored and graphed glucose readings uploaded remotely by the patients using a standard glucometer. Both patients and providers had access to the Web site, where the data could be viewed, analyzed and discussed.

 Mean glucose levels declined over the three-month pilot period, as did self-reported HbA1c levels.

"Diabetes Connected Health has the potential to truly impact the way diabetes care is delivered and to improve both clinical and economic outcomes," said Alice Watson, MD, corporate manager of the Center for Connected Health and a co-author of the paper.  "Self-monitoring of blood glucose may have a greater impact when patient data can be shared with a provider in a timely manner, leading to treatment changes and enhanced patient education and motivation."
