Real-time continuous glucose monitoring (CGM) significantly reduces the time spent in hypoglycemia (interstitial glucose <63 mg/dL) and lowers HbA1c in patients with type 1 diabetes compared to standard self-monitoring of blood glucose (SMBG).
If you have Type 1 Diabetes, using a real-time continuous glucose monitor (CGM) can significantly reduce the amount of time your blood sugar spends in dangerous low ranges compared to using standard finger-prick tests. This technology also helps lower your overall average blood sugar (HbA1c) without increasing the risk of hypoglycemia, which is a common trade-off with intensive insulin therapy. To get these benefits, you need to be committed to wearing the sensor continuously and adjusting your insulin based on the real-time data provided.
The time per day spent in hypoglycemia was significantly shorter in the continuous monitoring group than in the control group (mean 6 SD 0.48 6 0.57 and 0.97 6 1.55 h/day, respectively; ratio of means 0.49; 95% CI 0.26–0.76; P = 0.03). HbA1c at 26 weeks was lower in the continuous monitoring group than in the control group (difference 20.27%; 95% CI 20.47 to 20.07; P = 0.008).
Why this rating
Randomized, controlled, multicenter trial with intention-to-treat analysis, though not double-blinded for the intervention group.
