Beyond glycemic metrics: Real-world benefits of connected insulin pens in type 1 diabetes

Diabetes Res Clin PractPublished Prospective cohort study

Authors' conclusion

Connected insulin pens enhanced glycemic control, mitigated glucose variability and improve patient-reported outcomes.

Study context

Population
People with T1D treated with MDI and CGM; no change in treatment regimen or insulin type
Participants
220 people
Exposure
After vs before 12 weeks of connected insulin pens
Outcome
Glucose control and patient-reported outcomes
Follow-up
12 weeks
Methodological detailsmulticentre, real-life clinical practice, before-after (baseline vs 12 weeks)
  • Multicentre
  • Real-life clinical practice
  • Before-after (baseline vs 12 weeks)

Main finding

As reported in the abstract

12 weeks
  • Time in range (TIR), hypoglycaemia awareness and patient-reported outcomes improved and HbA1c decreased
  • Time with glucose 120-140 mg/dl increased; time 240-300 mg/dl decreased

Observational data: associations, not effects.

Further findings

Omitted and delayed insulin doses

%

Omission of basal insulin doses
33.8
Omission of prandial insulin doses
65.7
Delayed injections
90.5

Impact of omitted and delayed doses on glycaemic control

Basal omission had greater impact than prandial omissions: increase in variability indexes and time above range, decrease in TIR and TTIR
10/16 variability indexes
Delayed prandial doses increased variability parameters
7/16
