Background: Time in tight range (TITR) is a new metric applied to continuous glucose monitoring (CGM) data. We investigated the relationship between readings in tight range (RITR) and readings in range (RIR) using blood glucose meter (BGM) data in people with type 1 diabetes (PwT1D) using the OneTouch Reveal® diabetes app.
Methods: Anonymized glucose and app analytics were extracted from our server for 23,147 PwT1D. Glycemic data from their first 14 days using the app and meter were compared to the 14 days prior to a 180-day timepoint using paired within-subject differences.
Results: Glucose RITR (70-140 mg/dl) improved by +5.3 percentage points (%pts) (from 36.5 to 41.8%) in PwT1D performing 1 to 2 app sessions per week and this increased to +11.2 %pts (from 41.9 to 53.0%) in those performing >4 to 10 app sessions. Those performing 1-2 app sessions spent 9 minutes per week on the app compared to 38 minutes in those performing >4-10 sessions. Trends in % RITR with increasing app engagement were mirrored by improving % RIR, lower mean glucose, and reductions in % hyperglycemic readings (see Figure 1, P<0.001 for all).
Conclusion: Real-world data from 23,147 people with type 1 diabetes found improved percent readings in tight range with increasing engagement with the OneTouch Reveal® diabetes app.
