Automated insulin delivery is a technology for managing type 1 diabetes that goes by many names: hybrid or full closed loop, artificial pancreas system (APS), “looping”, and more. But whatever you call them, automated insulin delivery systems are not all the same. You have choices, ranging from the type of insulin pump body and CGM you want to use, to the algorithm and controller, to the interoperability and remote monitoring options, and more. Like switching from multiple daily injections to an insulin pump, switching from manual diabetes to automated insulin delivery has a learning curve.
