Correct answer: B — Automated insulin delivery (hybrid closed-loop) system

Automated insulin delivery (AID/hybrid closed-loop) systems combining CGM with algorithm-driven insulin pump delivery are the most effective technology for reducing severe hypoglycaemia in patients with impaired awareness. They automatically suspend or reduce basal insulin when glucose is falling and increase it when rising. Systems available in Australia include Medtronic 780G, Tandem Control-IQ, and CamAPS FX. PBS subsidises CGM for eligible patients.
