Diabetes Connected Health Study
A Randomized Clinical Trial of a Secure Website Shared Between Patients and Providers for Blood Glucose Monitoring in Type-2 Diabetes

Currently, diabetic patients who receive their care at the diabetes clinic self monitor their blood glucose using a portable glucometer, under the direction of care providers at the clinic. We propose to conduct a randomized controlled trial to examine the effect of the "Diabetes Connected Health" tool, which is a secure website shared between patients of Type-2 Diabetes and their providers and displays (subjects') blood glucose values in graphical format. The study will be carried out through multiple primary care practices within the Partners/PCHI Network. We hypothesize that implementation of the Diabetes Connected Health Tool will result in overall better Diabetes Care, in terms of better blood glucose control, improved patient-provider interaction, and better patient satisfaction towards their care.

The study will be carried out at multiple practices within Partners HealthCare system and will have one Intervention and one control arm.

Subjects enrolled into the intervention arm will use a OneTouch Ultra2 glucometer and an iMetrikus modem device which will upload the blood glucose readings to a secure, login-enabled web-based portal. Subjects will be given login information to access to their own individual Internet site, where they can view their readings and detailed graphical representation of their blood glucose levels over time, read educational material regarding diabetes management and receive personalized tips and feedback from their physicians (who will also have access to their patients' information on the web portal).

Subjects enrolled into the control arm will have access to the same glucometer and modem, and will have access to another individual internet website (the "Basic Site") which will show their glucose readings and graphical representation of glucose levels. Each patient will be enrolled for 3 months. and the primary outcome measure will patient and provider satisfaction with the Diabetes Connected Health tool.The specific aims along with hypothesis of the study are:

  1. To develop a web-based application ("Diabetes Connected Health") that will enable home-based glucose monitoring results to be readily incorporated into clinical glycemic management.

    Hypothesis: We hypothesize that through a development process incorporating interactive feedback loops between software developers, patients, clinicians, and other stakeholders, we can create a web-based clinical application that will be adopted by clinical practices.

  2. To test the clinical impact of the "Diabetes Connected Health" tool in a randomized clinical trial.

Hypothesis: We hypothesize that implementation of the tool will have a beneficial impact relative to control patients in several critical domains:

Patient Domains

  1. Increase patients' knowledge of their diabetes management plan.
  2. Increase patients' satisfaction with their clinical care.
  3. Increase patients' awareness of why they have high and/or low glucose readings.
  4. Increase patients' satisfaction with patient-provider communication.

Provider Domains

  1. Increase clinician satisfaction with clinical care.
  2. Increase clinician knowledge of individual patient care issues.

Clinical Outcome Domains

  1. Reduced incidence of out of range glucose results. (highs and lows)
  2. Increase rate of medication intensification.

Diabetes Mellitus, Type 2
Device: Subject/Provider Collaborative portal (the "Diabetes Connected Health" tool)
Subjects enrolled into the intervention arm will use a glucometer, a modem device which will upload the blood glucose readings to a secure, web-based portal (the "Diabetes Connected Health" tool) where they can view a detailed graphical representation of their blood glucose levels over time, read educational material regarding diabetes management and receive personalized tips and feedback from their physicians (who will also have access to their subjects' information on the web portal and contact them by an embedded messaging system). Subjects with new high or low readings will be flagged. Providers can initiate messages to subjects regarding symptoms or medications. A medication summary and log of all readings uploaded with date/time will be displayed on the website as well as a graphical display of all uploaded glucose readings over time and will require the subject to enter comments regarding each critical reading.
