Determining the Effect of Home BLOOD Glucose Monitoring on HBA1C in Patients With Type 2 Diabetes Using Smartphone Application

The purpose of this study is to evaluate the effectiveness of a web and mobile-based clinical decision support and monitoring system (1B4T mobile application) on blood glucose control, medication adherence, quality of life, and self-management in patients with poorly controlled Type 2 Diabetes Mellitus.

This open-label, parallel-group, randomized controlled trial was conducted with 100 type 2 diabetes patients registered at primary care family health centers in Izmir, Turkey. Participants were randomly assigned to either the intervention group (n=50) or the control group (n=50).

• Intervention Group: Participants installed the 1B4T mobile application on their smartphones, created personal accounts, and recorded their home blood glucose measurements through the app for 3 months. The app allowed patients to track their previous data and view a 10-day blood glucose prediction without directing any treatment changes.
• Control Group: Participants continued with their routine healthcare follow-ups and standard controls.

At baseline and at the 3-month follow-up, fasting plasma glucose and HbA1c levels were measured for all participants. Additionally, sociodemographic characteristics, medication adherence (Modified Morisky Medication Adherence Scale), quality of life (WHOQOL-BREF-TR), and diabetes self-management (Diabetes Self-Management Questionnaire - DSMQ) were evaluated to assess the clinical and behavioral outcomes of the mobile health intervention.

Inclusion Criteria:

• Volunteering to participate in the study.
• Having poorly controlled Type 2 Diabetes Mellitus (HbA1c > 7%).
• Using a smartphone.
• Being over 18 years of age.
• Ability to speak and understand Turkish.
• Being at least a primary school graduate.
• Having full orientation to person, place, and time.

Exclusion Criteria:

• Having participated in any diabetes-related study within the last 3 months.
• Inability to attend regular clinical follow-up visits.
• Having severe visual or hearing impairments.
