A Randomized Clinical Trial of a Secure Website Shared Between Patients and Providers for Blood Glucose Monitoring in Type-2 Diabetes
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 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:
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.
To test the 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
Provider Domains
Eligibility Criteria for Partners HealthCare practices:
Manage type-2 Diabetes patients.
Have at least one non-Physician provider (nurse practitioner, nurse, diabetes educator) with responsibility for diabetes patient care
Inclusion Criteria for subject selection:
Diagnosis of type 2 diabetes
Age 18 years or older
English speaking/able to read English
Last measured Hemoglobin A1c (HbA1c) > 7.5 % in the last 12 months.
Prescribed glucose self-monitoring, and either currently self monitoring or willing to monitor their blood glucose, as prescribed by their care provider, using the OneTouch Ultra2 portable glucometer.
Access to the Internet for the 6 months the study will run.
Access to a compatible analog telephone line at either their work place or home such that the subjects are able to upload the glucometer readings to the website.
Access to an active email account.
Receiving diabetes care primarily within the practice.
Exclusion Criteria for subject selection:
Subjects having mental health, cognitive or physical impairments that would preclude the set up and use of the modem, glucometer or computer.
Subjects are not candidates for guideline-based diabetes care.
