Poor Patient Adherence May Undermine Aim of Continuous Glucose Monitoring

JAMA. 2007;298(6):614-615. doi:10.1001/jama.298.6.614

Chicago—The approval in 2006 of continuous glucose monitoring (CGM) devices brought hopes that providing patients with type 1 diabetes with real-time information from a sensor implanted just under the skin would allow them to achieve better glycemic control. However, researchers have had a tough time showing efficacy of CGM in the clinic due to such factors as problems with device calibration and a lack of rigorous trial data.

A study presented at the American Diabetes Association’s 67th Scientific Sessions, held here in June, suggests that yet another element may limit how well CGM translates into glycemic control: patients who are indifferent to taking action to adjust their blood glucose level based on the information generated by CGM.
