IntroductionType 1 Diabetes Mellitus (T1DM) requires lifelong exogenous insulin therapy, along with self-management strategies, such as carbohydrate counting, to appropriately adjust insulin doses in response to meals. However, many patients face challenges in adhering consistently to carbohydrate counting, compromising glycemic control and increasing the risk of diabetes-related complications. Emerging technologies, such as artificial intelligence (AI), hold significant potential for optimizing disease management by enhancing the accuracy and efficiency of self-care practices. ObjectiveThe primary aim of this study is to evaluate the efficacy and safety of the AI-based tool Tia Bete, designed to assist patients with T1DM in carbohydrate counting and insulin dose adjustment. The tool provides real-time recommendations based on personalized insulin-to-carbohydrate ratios, insulin sensitivity factors, and individualized glycemic goals. MethodsThis is a prospective, longitudinal study involving 40 patients with T1DM, stratified into two cohorts: 20 children and adolescents (6-18 years) and 20 adults (\>18 years), recruited at the Hospital das Clínicas, University of São Paulo (HCFMUSP). Participants will be assessed before and after six months of using the Tia Bete tool. Glycemic control will be evaluated using parameters such as glycated hemoglobin (HbA1c), time in range, and the incidence of hypoglycemia and hyperglycemia. Quality of life and satisfaction with the tool will also be assessed. Overview of the AI Tool Launched in June 2024, Tia Bete is an AI-based digital solution designed to facilitate glycemic control and improve quality of life for patients with T1DM. By offering real-time assistance with carbohydrate counting and insulin dose recommendations, the tool aims to enhance patient autonomy while enabling flexible treatment adherence in collaboration with their multidisciplinary healthcare team. Results and ConclusionsPreliminary data indicate high engagement, with over 35,000 active users interacting with the platform at least four times per week. Initial findings suggest significant improvements in glycemic control, as well as increased confidence in carbohydrate counting and insulin dose adjustments. The dissemination of this project is crucial for advancing T1DM care, offering a scalable, accessible, and effective technological solution. Final results are expected by October 2025.
