Summary

Introduction: Accurate insulin bolusing requires advanced knowledge of carbohydrate counting and correction doses, which can be supported by mobile technology.

Objective: To evaluate the effectiveness and safety of a mobile application for carbohydrate counting and bolus calculation (CHOC-BC) in adults with type 1 diabetes mellitus (T1DM).

Methods: This is a 12-week randomized controlled trial conducted at King Fahad Medical City. Adults with T1DM using multiple daily insulin injections and Libre flash glucose monitoring systems are randomly assigned to either the CHOC-BC intervention group or a control group receiving conventional treatment. The primary endpoint is the time in range (TIR; 70-180 mg/dL).

Conditions

  • Diabetes Mellitus, Type I

Interventions

OTHER

Standard Treatment

The control group followed a standard diabetic habitual diet

DEVICE

Carbohydrate

Eligible participants provided informed consent and underwent baseline assessments, including demographics, medical history, insulin doses, and fasting blood samples for HbA1c and lipid profile. Participants used the FreeStyle Libre 2 sensor, with AGP data collected bimonthly. The primary outcome was Time in Range (TIR, 70-180 mg/dL), while secondary outcomes included TAR, TBR, GV%, GMI, HbA1c, and BMI. A registered dietitian provided structured CHOC-BC education. The intervention group used the CHOC-BC app, validated against expert-calculated carbohydrate counts, while the control group followed standard diabetes education. Virtual follow-ups occurred bimonthly for three months. At study completion, HbA1c, lipid profile, insulin doses, weight, and AGP data were collected for comparison.
