G6 continuous glucose monitoring system feature use and its associations with glycaemia in Europe
Authors' conclusion
Individuals who utilised the Dexcom G6 features showed better glycaemic control, particularly among those who utilised more sensitive High alert and Low alert settings, than users who did not utilise the system features.
Study context
- Population
- Europe-based Dexcom G6 continuous glucose monitoring (CGM) users (Germany/Austria/Switzerland region, Nordic countries, UK, Italy, France, Spain)
- Participants
- 47,784 users
- Exposure
- Enabled vs disabled G6 alert features
- Outcome
- Associations between utilisation and customisation of High/Low threshold alerts, urgent low soon (ULS) alert, and established CGM metrics
- Follow-up
- 6 months
Methodological detailslarge database analysis, anonymised data
- Large database analysis
- Anonymised data
Main finding
As reported in the abstract
- Enabling Low alert and urgent low soon (ULS) alert associated with lower %TBR vs disabling Low alert
- p < 0.001
- Enabling High alert associated with higher %TIR and lower %TAR vs disabling High alert
- p < 0.001
Observational data: associations, not effects.
Further findings
Alert threshold settings by age
- Paediatric patients and older adults tended to set higher High/Low alert thresholds; younger adults tended to use lower thresholds
