- Arm 3: Once Daily Testing with Enhanced Feedback This Arm represents an enhanced, patient-centered approach. Participants randomized to Arm 3 will, like the Arm 2 participants, be instructed to test once daily and at different times of the day, and their glucose values will be transmitted wirelessly to a server. However, for Arm 3 participants, the blood glucose values will be analyzed automatically each time a value is transmitted. Based upon the value, instantaneous personalized feedback will be provided via wireless messaging to the patients' glucose meters. These messages will not include suggestions for pharmacological therapy modification but will be motivational in nature, including suggestions to enhance efforts at lifestyle management and adherence to pharmacologic therapy if prescribed. At weekly intervals, an analysis of the SMBG values from the previous week will be sent to the glucose meter highlighting trends and identifying specific problematic times. Subjects will also receive messages reminding them of upcoming clinic visits (beginning 1 week prior to their scheduled visit). As with Arm 2, SMBG results and customized reports will be downloaded and reviewed at all clinic visits by the primary care provider. In addition, a summary of the messages sent wirelessly to the patient since the most recent visit will be included. Like the glucose values report, this message report will be given to all providers at the beginning of the clinic visit and providers will be asked to also review these results with the patient. Providers will make appropriate treatment recommendations based upon blood glucose trends and messages. Report recommendations will be driven by an algorithm for treatment modification based upon ADA treatment guidelines and include suggestions for lifestyle and pharmacotherapy adjustments. At the end of the clinic visit, patients will be instructed by their primary care provider to continue testing their blood glucose once daily and collaboratively determine the testing approach (e.g., timing of once daily testing) the patient will employ over the next monitoring period.
