Lived experience of fully closed-loop insulin delivery in adolescents with type 1 diabetes and HbA1c above target
Authors' conclusion
In adolescents with type 1 diabetes, fully closed-loop insulin delivery reduced the daily burden of self-management, leading to improved quality of life.
Study context
- Population
- Adolescents with T1D and HbA1c above target (≥7.5 % [58 mmol/mol])
- Participants
- 12 adolescents
- Outcome
- Lived experience of fully closed-loop insulin delivery
Methodological detailsvirtual semi-structured interviews, thematic analysis, inductive-deductive approach
- Virtual semi-structured interviews
- Thematic analysis, inductive-deductive approach
Main finding
As reported in the abstract
- All interviewees reported reduced effort in managing diabetes (no carbohydrate counting or bolusing) and less worry about glucose levels
- Improved quality of life, greater sense of freedom and normalcy, particularly around meals
- A few noted benefits in physical activity, sleep, work and social life
- Dissatisfaction with the algorithm's slow response to postprandial glucose spikes and the need for a tethered pump
Further findings
Quality of life questionnaires
- No significant differences in hypoglycaemia fear or diabetes distress between study periods; positive experience with the closed-loop system
