Hybrid closed-loop systems for managing type 1 diabetes are now available and rapidly being integrated into routine clinical practice. Insulin delivery is automated in a closed-loop system via an algorithm that uses CGM data to direct insulin delivery via an insulin pump, but users need to carbohydrate count and give pre-prandial insulin to achieve optimal outcomes. Understanding the principals of closed-loop insulin delivery, and how it differs from traditional insulin pump therapy, is key to supporting and educating children and young people with type 1 diabetes using these systems. Additionally, healthcare professionals need to be able to provide specific guidance and help set realistic expectations about an increasing number of different systems available. Structured approaches to closed-loop data review are essential for post-initiation reviews and therapy optimisation. This presentation reviews basic concepts of closed-loop insulin delivery, shows universal approaches to reviewing closed-loop data, and highlights capabilities and key similarities and differences of current systems with tips for optimisation.
