The Sukaribit Smartphone App for Better Self-Management of Type 2 Diabetes: Randomized Controlled Feasibility Study

Area of Science:

• Digital health interventions
• Diabetes management
• Feasibility studies

Background:

• A novel mobile application, Sukaribit, was developed to facilitate communication between caregivers and patients with type 2 diabetes.
• The app aimed to enhance patient self-care and improve glycemic control, measured by hemoglobin A1c (HbA1c).

Purpose of the Study:

• To assess the feasibility of the Sukaribit app intervention and study methodology.
• To gather data for planning a larger, more robust effectiveness study.

Main Methods:

• A randomized controlled feasibility study with a mixed-methods design was conducted.
• Adults with type 2 diabetes were randomized into an intervention group (n=28) using Sukaribit for 2 months or a control group (n=31) receiving standard care.
• Measurements included HbA1c, diabetes distress, physical activity, and self-care, with feasibility assessed against 5 progression criteria.

Main Results:

• Recruitment exceeded expectations; however, only 2 of 5 progression criteria were met.
• Self-reported data collection was successful, but home HbA1c testing proved problematic.
• The intervention group showed a modest increase in daily blood glucose tests (0.6 more per day).

Conclusions:

• Participant recruitment for future studies appears feasible with modifications.
• Significant challenges exist with home HbA1c testing and intended app utilization, requiring alternative strategies.
• The Sukaribit app and study procedures require substantial improvements before a larger effectiveness trial can proceed.
