Real-World Follow-Up of People With Type 2 Diabetes Using a Mobile Diabetes App With Connected Glucose Meters Finds Improvements in Glycemia Are Durable Over 5 Years
Authors' conclusion
Real-world follow-up of people with type 2 diabetes using a diabetes app with connected meters found improvements in glycemia were durable over 5-years.
Study context
- Population
- People with T2D using a diabetes app with connected glucose meters, ≥365 blood glucose (BG) readings per year
- Participants
- 501 people
- Exposure
- Last 14 days of each year vs first 14 days of diabetes app use with connected meters
- Outcome
- Glycemic changes over 5 years (first 14 days of app use vs last 14 days of each year)
- Follow-up
- Year 1 and year 5
Methodological detailspaired within-subject differences, anonymized app and glucose data
- Paired within-subject differences
- Anonymized app and glucose data
Main finding
As reported in the abstract
- BG readings in range (RIR, 70-180 mg/dL), year 1: 74.6% to 81.5%
- +6.9 percentage points
- Readings in tight range (RITR, 70-140 mg/dL), year 1: 49.2% to 57.0%
- +7.8%pts
- RIR, year 5
- +7.5%pts
- RITR, year 5
- +7.7%pts
- Mean BG, year 1: 150.2 to 141.1 mg/dL
- −9.1 mg/dL
- Mean BG, year 5: 150.2 to 139.6 mg/dL
- −10.6 mg/dL
- All glycemic changes significant
- p<0.001
Observational data: associations, not effects.
Further findings
Hyperglycemic readings (>180 and >250 mg/dL) · 5 years
- Reductions in hyperglycemic readings explained the improvements in RIR and RITR
BG check frequency · 5 years
- BG checks per day, consistent over 5 years
- 1.8 to 2.1
App engagement
- Higher app engagement (>4 app sessions per week) effected better diabetes management
