Lived experience of advanced hybrid closed-loop versus hybrid closed loop: patient-reported outcomes and perspectives.

This paper reports on the lived experience of Medtronic Advanced Hybrid Closed-Loop (AHCL) in comparison to first generation hybrid closed-loop (HCL) in a randomized, open-label, two-period crossover trial. Patient-reported outcome measures (PROs) were administered prior to randomization and at the end of each study period in 113 adolescents and young adults with type 1 diabetes. Glucose monitoring satisfaction subscales for emotional burden and behavioral burden improved significantly (p<0.01) over time with use of AHCL versus HCL, and co-occurred with glycemic improvements (reduced percent time above 180 mg/dL during the day and no change in % time less than 54 mg/dL across 24 hours) and greater time in Auto Mode. PROs including distress, technology attitudes, and hypoglycemia confidence were not different. AHCL use was associated with improved glucose monitoring satisfaction. Satisfaction was greater in those participants who had more appreciable glycemic benefit and stayed in Auto Mode more often.
