Are Automated Insulin Delivery Devices Useful for Patients with Type 2 Diabetes?

Automated insulin delivery systems are insulin pumps that use continuous glucose monitoring (CGM) data to adjust insulin delivery automatically. These devices already are available for patients with type 1 diabetes, but their use in patients with type 2 diabetes has not been evaluated broadly.

In this industry-sponsored North American trial, researchers randomized 319 adults with type 2 diabetes who used insulin (multiple daily injections or traditional insulin pump) either to use an automated delivery system or to continue their usual method of insulin use; all patients received CGM. Patients who took other guideline-recommended medications were well represented. After 13 weeks, glycosylated hemoglobin (HbA_1c) decreased significantly more i…
