Does Continuous Glucose Monitoring Use Prompt Greater Engagement in Self-Management? A Randomized Controlled Trial Focusing on Adults With Type 2 Diabetes

These findings suggest that introducing CGM to adults with T2D heightens users' engagement with their own diabetes care and also improves glycemic control more than providing SMBG.
Study context
- Population
- Continuous glucose monitoring (CGM)-naïve adults with T2D and home-test HbA1c >7.5%
- Participants
- 110 adults
- Comparison
- CGM vs self-monitoring of blood glucose (SMBG)

- HbA1c change (baseline to 3 months) — CGM: HbA1c 9.2% to 8.3%, P < .001, d = .65 · likely due to limited sample size
- ≈1% · P = 0.170
- HbA1c change (baseline to 3 months): effect of group on HbA1c change not statistically significant
HbA1c change (baseline to 3 months)
- SMBG: HbA1c 8.9% to 8.4%, P = .065, d = .30
