The use by diabetes patients of real-time Continuous Glucose Monitoring (CGM) system is becoming widespread and has changed diabetic practice. Automated closed-loop (CL) insulin therapy has come of age. This major technological advance is expected to significantly improve the quality of care for adults, adolescents and children with type 1 diabetes. Questions remain about patients' perception and acceptance on this automatisation of the management of their glycemic variability. Thus this study is built to evaluate the impact of the activation of the closed-loop on quality of life and burden of their diabetes in patients with type 1 diabetes under CSII.
This cohort study will follow patients with type 1 diabetes undergoing under continuous subcutaneous insulin infusion (CSII) with Continuous Glucose Monitoring (GCM). After inclusion visit, there's a 20 days' period to assess their quality of life and perception of the burden of their diabetes and confirm their eligibility to the closer-loop. During this 20 days' period, patients should complete all the self-questionnaires. Then, during the 2d visit, the closed-loop will be activated by the diabetologist for a 6 months follow-up including six visits with 3 phone contacts (at week 1, week 2 and week 6) then 2 direct visits at 3 months and 6 months. The 3 phone contacts are mainly planned, as recommended in French guidelines, to ensure the good use of the device and to detect or prevent any unexpected events. The 2 visits at 3 and 6 months, are planned to assess the glycemic variability using Continuous Glucose Monitoring data and to collect perception of the patients via the 2 main criteria self questionnaires (Quality of life and burden to be filled-in by patients at 3 and 6 months) and all perception dimensions by all the self questionnaires. Main results will provide data on the evolution of quality of life and burden of diabetes by comparison between scores at 6 months and baseline, and evolution of glycemic variability.

After a run-in period of 20 days to co,firm eligibility, the closed loop is activated and patients are followed for 6 months by their diabetologists.
Change in Quality of life following activation of closed loop
Validated self questionnaire : Audit of Diabetes dependant quality of life (ADQQoL) with 19 items Lower scores reflect worsening quality of life
Time frame: Score comparison between Baseline and 6 months after activation of closed loop
Change in burden of diabetes following activation of closed loop
Validated self questionnaire : Problem Areas s in Diabetes (PAID) with 20 items. Higher scores reflect greater emotional distress.
Time frame: Score comparison between Baseline and 6 months after activation of closed loop
Perception of patients
Different validated self questionnaires on well-being, Fatigue, Anxiety and Depression, Physical activity, Sleep, Fear of hypoglycemia and personality.
Time frame: Before and 6 months after activation of closed loop
Glycemic variability
Collection of symptomatic hypoglycemic and hyperglycemic events. Data from GCM including time in range, time above range, time below range and glycemic variability coefficient.
Time frame: Before, 3 months and 6 months after activation of closed loop
