Professional Continuous Glucose Monitoring as an Adjuvant Educational Tool for Improving Glycemic Control in Patients With Type 2 Diabetes.

The investigators conducted a three-month quasi-experimental study with an intervention and control group and ex-ante and ex-post evaluations in one family medicine clinic in Mexico City. Participants were type 2 diabetes patients with HbA1c\>8 mg/dL attending a comprehensive diabetes care program (MIDE). In addition to the program, the intervention group wore a professional CGM sensor (iPro™2) during the first six days of the study. Following this period, intervention group participants had a medical consultation for the CGM results and treatment adjustments. Additionally, the intervention group participants received an educational session and a personalized diet plan from a dietitian. After three months, the intervention group again wore the CGM sensor for one week. The primary outcome variable was HbA1c level measured at baseline and three months after the CGM intervention. The investigators analyzed the effect of the intervention on HbA1c levels by estimating the differences-in-differences treatment effect. Additionally, baseline and three-month CGM and dietary information was recorded for the intervention group and analyzed using the Student's paired t-test and mixed-effects generalized linear models to control for patients' baseline characteristics.
