Associations of bolus insulin injection frequency and smart pen engagement with glycaemic control in people living with type 1 diabetes

Diabetes Obes MetabPublished Retrospective cohort study

Authors' conclusion

Glycaemic control was associated with daily bolus insulin injection frequency and smart pen engagement. A treatment regimen combining an optimal bolus injection strategy, and effective smart pen engagement, may improve glycaemic control among adults with T1D.

Study context

Population
Adults with T1D using a smart pen (NovoPen 6) for bolus insulin (fast-acting insulin aspart or insulin aspart) alongside CGManalysed
Participants
1,194 adults
Exposure
Bolus insulin injection frequency and smart pen engagement vs glycaemic control
Outcome
Glycaemic control (glucose metrics, TIR 3.9-10.0 mmol/L)
Methodological detailsreal-world data
  • Real-world data

Main finding

As reported in the abstract

TIR by daily bolus injection frequency
Number of daily bolus injections associated with time in range (TIR)
P < 0.0001
Estimated chance of >70% TIR with three daily bolus injections on average
11%
Observed mean daily bolus injections vs optimal number for glycaemic targets
4.8 injections vs. 6-8 injections

Observational data: associations, not effects.

Further findings

Smart pen engagement significantly associated with improved TIR
