简要总结
The objective of the study is to determine whether patients with poor glycemic control can improve metabolic control using the real-time values of the Guardian® RT compared to conventional self-monitoring blood glucose finger-sticks.
详细描述
Finger-stick based self-testing (SBGM), as well as diagnostic continuous glucose monitoring (CGMS®) allow diabetic patients to find a balance between the two hyper- and hypoglycemic extremes. Nevertheless, there are still patients who fail to achieve good control due to fear of hypoglycemia, or who underestimate post-prandial hyperglycemias.
The Guardian® RT Telemetered Glucose Monitoring System is indicated for continuous or periodic monitoring of real-time interstitial blood glucose values and low/high blood glucose alarms (when pre-set levels are reached) in persons with diabetes mellitus. The glucose values calculated by the device will be used to trigger hypo- and hyperglycemia alerts and will be displayed every 5 minutes. The Guardian® RT stores up to 21 days of data.
The overall primary objective of the study is to determine whether patients with poor glycemic control as evidenced by HbA1c > 8.1% can achieve improved metabolic control using the real-time values of the Guardian® RT compared to conventional self-monitoring blood glucose finger-sticks (control group) after 12 weeks of continuous use.

- •Patients must be using only insulin analogues or rapid-acting human insulin for their meal boluses.
- •Patients are willing to undergo all study procedures.
- •Patients are trained on how to adapt their insulin dose to their meals and are knowledgeable concerning how to calculate and apply corrective insulin boluses post-prandially, as well as on the influence of physical activity and other life style factors on their glycemia.
- •Patients are willing to participate in a Guardian® RT product training course
- •Patients understand how to adjust and administer corrective treatment.
排除标准
