Impact of Continuous Glucose Monitoring Sourcing on Real-World Adherence and Health Care Costs: A Comparative Analysis by Insurance Type

This real-world analysis compared adherence rates, total health care costs, and health care resource utilization of individuals receiving continuous glucose monitoring (CGM) supplies through durable medical equipment (DME) providers versus through pharmacies, according to insurance type. Patients in the DME cohort had higher adherence rates than those in the pharmacy cohort. Total costs were lower for Medicare/Medicare Advantage patients getting supplies from a DME than for patients getting supplies from a pharmacy. Among those with commercial insurance, health care utilization was lower in the DME cohort than in the pharmacy cohort. Sourcing CGM supplies from DME providers versus pharmacies may yield benefits on adherence, health care costs, and resource utilization.
