The effectiveness of continuous glucose monitoring with remote telemonitoring-enabled virtual educator visits in adults with non-insulin dependent type 2 diabetes: A randomized trial

Aims

Estimate the effectiveness of continuous glucose monitoring (CGM) with remote telemonitoring-enabled virtual diabetes educator visits for improving glycemic management in adults with type 2 diabetes, not on insulin.

Methods

Participants with type 2 diabetes, not on insulin, and HbA1c > 7.0 % were enrolled in an open-label randomized trial of 6 weeks of CGM with telemonitoring versus enhanced usual care. Both groups received educator visits. HbA1c was assessed at 12 weeks.

Results

Of 105 participants (mean age 57.3 years, 49.5 % females, mean baseline HbA1c 8.0 %), 86 remained at follow-up. Change in HbA1c was −0.69 % (CGM) versus −0.33 % (enhanced usual care). Adjusting for baseline HbA1c, CGM was superior (0.65 % greater HbA1c reduction [95 % CI 0.17–1.12 %], p = 0.008). CGM participants were 92 % (RR = 1.92, 1.19–3.06, p = 0.007) more likely to have an HbA1c reduction ≥ 0.5 %, lost more weight (difference in weight reduction 2.17 kg, 0.22–4.11, p = 0.029) and were more satisfied with their treatment. No treatment-related adverse events were observed.

Conclusions

CGM with virtual diabetes educator visits is effective, safe, and acceptable in adults with type 2 diabetes not on insulin and should be considered as an alternative to drug therapy for improving blood glucose.
