This project involves a series of research projects that forms part of my PhD. The work aims to evaluate the impact of wearable technologies such as DIY-CGM and AHCL on both the glucose monitoring and glucose management of patients with type 1 diabetes and their families. We begin by evaluating the clinical efficacy of DIY-CGM compared to flash glucose monitoring by evaluating differences in measures of glycemic control, including Time in Range, its impact on a range of psychosocial characteristics such as fear of hypoglycemia, and diabetes-related distress in both patients with type 1 diabetes and their families. We will then evaluate the ability of advanced insulin delivery methods to enhance and optimise glycemic control, sleep quality and sleep quantity in these patients and their families. Finally, we reflect on the lives of patients and their families who use advanced diabetes technology in a series of qualitative studies.
