Insulin Delivery and Glucose Monitoring Methods for Diabetes Mellitus: Comparative Effectiveness

Slide: 7 of 25

Background: Managing Diabetes With Glucose Monitoring and Glycemic Control (2 of 2)

SMBG allows more specific and timely feedback on hyperglycemia and allows patients to evaluate their individual response to therapy. It has been shown to be a component of successful diabetes management.

rt-CGM equipment consists of a transcutaneous glucose sensor that is connected to a transmitter and receiver. Physicians currently recommend rt-CGM for patients with type 1 diabetes who have hypoglycemia unawareness, frequent hypoglycemia where their HbA1c is over the recommended target, or excess glycemic excursions. They also recommend rt-CGM for patients who are in preconception planning or are pregnant.

The challenges of using SMBG include the associated pain, costs, behavioral and technical skills, required motivation, and intrusiveness that affect adherence to this technique. With rt-CGM, success in lowering blood glucose levels depends on adherence to ongoing use of the device.
