Longitudinal analysis of users transitioning from the Dexcom G5 to the G6 RT‐CGM system in Germany, Sweden and the United Kingdom (2018–2020)
Authors' conclusion
Similar RT-CGM trends were observed across Germany, Sweden, and the UK. Improvements in hypoglycaemia occurred in all countries. The high retention of users may lead to sustained glycaemic benefits associated with RT-CGM use.
Study context
- Population
- Users in Germany, Sweden and the United Kingdom (UK) who transitioned from Dexcom G5 to G6 between 9–12 months after G6 launched in 2018
- Exposure
- Dexcom G6 vs Dexcom G5 Real-Time Continuous Glucose Monitoring (RT-CGM)
- Outcome
- % time in hypoglycaemia, % TIR, user retention rates, device utilisation, and urgent low soon (ULS) alert utilisation
- Follow-up
- 3-month intervals in the 2-year study window

Main finding
As reported in the abstract
Hypoglycaemia, TIR, retention, utilisation
- Decrease in median % time <3 mmol/L (54 mg/dL), months 0-3 after transition (range across countries)
- 0.12-0.28 percentage points
- Decrease in median % time <3.9 mmol/L (70 mg/dL), months 0-3 after transition
- 0.40-0.43 percentage points
- Further decrease in % time <3 mmol/L, months 3-6
- 0.11-0.21 percentage points
- Further decrease in % time <3.9 mmol/L, months 3-6
- 0.34-0.65 percentage points
- Retention rate at end of study window
- 88.8-94.8%
- ULS utilisation at end of study window
- 83.9-86.9%
Observational data: associations, not effects.
