AIMS: We evaluated de-intensification of basal-bolus insulin (BBI) after initiation of a GLP-1 receptor agonist (GLP-1RA) under routine care. RESEARCH DESIGN AND METHODS: This retrospective, multicenter study conducted at outpatient clinics in North-East Italy collected data on patients with T2D on BBI who initiated a GLP-1RA. Patients were divided according to whether they de-intensified BBI at the end of observation by stopping prandial insulin. RESULTS: We included 425 patients with mean age of 61.3 years and 13 years of diabetes duration. Baseline HbA1c was 8.6% and BMI was 35.5 kg/m2. After 14 months. 58.6% of patients de-intensified BBI after initiating GLP-1RA: they were younger, had a shorter disease duration, lower HbA1c and insulin dose, and less frequent microangiopathy than those who continued BBI. A probability estimation based on these variables was validated in an independent cohort of 40 patients. Body weight improved in both groups, but HbA1c and fasting plasma glucose significantly declined only among patients who de-intensified BBI. Patients who de-intensified BBI and persisted on GLP-1RA at the last observation (80.7%) had greater HbA1c reductions. CONCLUSION: Under routine care, GLP-1RA initiation frequently allowed discontinuing BBI, especially among patients with shorter disease duration, lower insulin requirement, and better glucose control.
