Brief Summary

Management of type 2 diabetes is an ongoing challenge for patients and their doctors. In order to prevent complications, patients need to monitor and control their blood sugar levels. In addition, they may need to have an ongoing communication with their doctor in order to modify treatment. In this study the investigators wish to compare the benefits of continuous glucose monitoring system (CGMS) to an internet-based glucose monitoring system (IBGMS). The investigators also want to determine whether the frequency of blood glucose testing affects blood glucose control and to see whether the benefits of CGMS and IBGMS are independent of testing frequency.

Conditions

Type 2 Diabetes Mellitus

Keywords

Remote Blood Glucose Monitoring System,; Continuous Glucose Monitoring System,; Self Monitoring Blood Glucose,; Strip Counting,; Type 2 Diabetes

Outcome Measures

Primary Outcomes (1)

• The primary endpoint is the A1c level or the change in A1c level

  6 Months

Secondary Outcomes (1)

• A secondary endpoint includes adverse events such as unplanned hospitalizations for any cause that last more than 24 hours

  6 Months

Study Arms (4)

Internet Intervention

ACTIVE COMPARATOR

The subjects enrolled in the Internet Therapeutic Intervention arm receive standard care by testing their blood glucose at least 3 times daily and visit the endocrinologist every 3 months; however, they are also asked to upload their blood glucose readings online every 2 weeks for the health practitioner to view and comment upon.

Other: Remote Blood Glucose Monitoring

Continuous Glucose Monitoring

ACTIVE COMPARATOR

The use of CGMS (Sensor, receiver, transmitter) plus the uploading of results to the Internet-based software utility of CareLink Personal and generating reports that can be viewed and used at the patient's own preference. This group will send the data to their endocrinologist and receive feedback based on the uploaded glucose data.

Other: Continuous Glucose Monitoring

SMBG

ACTIVE COMPARATOR

The SMBG patients will be told that we are testing a new meter to check the accuracy of the meter. They will be asked to test at least 3 times a day and to keep a written diary of their sugar levels. The SMBG group will not know that we are counting strips and can not know about the SMBG With Knowledge group as it may bias the frequency that they test.

Other: SMBG

SMBG With Knowledge

ACTIVE COMPARATOR

The SMBG With Knowledge patients will be given a new meter and will be asked to test at least 3 times a day and to keep a written diary of their sugar levels. We will inform this group that we are measuring the frequency of SMBG testing.

Also known as: Internet Blood Glucose Monitoring System

Internet Intervention

Continuous Glucose Monitoring OTHER

The use of CGMS (Sensor, receiver, transmitter) (Medtronic Diabetes) plus the uploading of results to the Internet-based software utility of CareLink Personal and generating reports that can be viewed and used at the patient's own preference. This group will not receive feedback or suggestion based on the uploaded glucose data.
