Abstract
Background and Aims: The accurate estimation of food carbohydrates (CHO) is essential for computing meal insulin doses and achieving optimal blood glucose (BG) control in patients with type 1 diabetes (T1D). We developed EKIYOU, a smartphone app that automatically computes CHO content of declared food intakes and corresponding bolus insulin dose. We assessed the outcomes of its use in a pilot two‐month study.Methods: Seventeen adults with T1D, under basal‐bolus insulin regimen, with variable skills in flexible insulin therapy participated in a two‐month study. The patients received EKIYOU application for two months. During the first month only carbohydrate counting (CC) app function was active. After ICR and CF revision, the bolus calculator was activated for the second month and patients relied on its calculation. After the two month period, 14‐day CGM TIR, TAR and TBR values were compared to that at inclusion.Results: Fifteen patients (age: 47 ± 10, 5 using CSII and 10 MDI, HbA1c: 7.7 ± 0.5 %) completed the study. Patients used on average EKIYOU 2.5 times a day for CC and bolus calculation. TIR increased from 53.87% at inclusion to 62.83% at the end of study. TAR decreased by 8.27% with no change of TBR. 73% of patients had a TIR increase above 7%.Conclusions: Our data suggests the benefits of using EKIYOU app to improve BG control through increased TIR. Patients felt satisfied and found EKIYOU easy‐to‐use and relieving. All patients succeeded to use the application even without previous education on CC and bolus adjustment.
