Interventions

  • C-Carbs Program — BEHAVIORAL
    The C-CARBS intervention is a patient-facing diabetes education program consisting of four weekly, one-hour sessions with a diabetes educator. The program teaches participants how to use continuous glucose monitoring (CGM) information, including current glucose levels and glucose trends, to guide mealtime insulin dosing. The intervention is designed to provide practical strategies for insulin dosing without relying solely on traditional carbohydrate counting. Participants will also practice applying CGM information to real-world meals and insulin dosing decisions.

Study Details

The goal of this randomized study is to learn whether a CGM-guided insulin dosing education program can help adults with diabetes improve how they dose mealtime insulin. The main question it aims to answer is: 1\. Does CGM-guided insulin dosing education improve insulin dosing behaviors and glycemic outcomes in adults with diabetes who do not routinely use carbohydrate counting? Participants will be randomly assigned to either the C-CARBS intervention or usual care. Participants will complete study visits, questionnaires, and meal and insulin logs, and CGM data will be collected to evaluate changes in insulin dosing behaviors and glycemic outcomes.
