Brief Summary

Type 1 diabetes requires a lot of work to try to keep glucose levels in the target range. Hybrid closed- loop, also known as artificial pancreas, takes glucose readings from a sensor (continuous glucose monitor) and uses an algorithm to tell an insulin pump how much insulin to deliver. Hybrid closed-loop has currently been rolled out to many people with type 1 diabetes in England. We are keen to develop a deeper understanding of the perspective of people living with type 1 diabetes who have choices about which hybrid closed-loop systems fit their needs. The main purpose of this study is to explore the choices and experiences of people living with type 1 diabetes regarding closed-loop therapy.
