Abstract Aim To identify insulin delivery system perceptions that contributed to improvements in overall satisfaction with insulin therapy (treatment satisfaction) that were larger in those using sensor‐augmented pump therapy than those using multiple daily injections with self monitoring of blood glucose. Methods The Sensor‐Augmented Pump Therapy for A1C Reduction 3 ( STAR 3), a randomized 12‐month clinical trial, compared sensor‐augmented pump therapy to multiple daily injections + self monitoring of blood glucose in adult and paediatric patients. The Insulin Delivery System Rating Questionnaire measured perceptions of convenience, problems, interference with daily activities, blood glucose monitoring burden, social burden, clinical efficacy, diabetes worries and psychological well‐being, as well as treatment satisfaction. We conducted separate multiple regression analyses for the 334 adult patients and 147 paediatric patients and their caregivers to assess the independent associations ( P < 0.05) between change from baseline to follow‐up in user perceptions and treatment satisfaction. Results Increased convenience was associated with improved treatment satisfaction in all user groups. Reduced interference with daily activities (caregivers), reduced social burden (adults) and increased efficacy (both) also were associated with improved treatment satisfaction. Conclusions Treatment satisfaction among children was primarily a function of convenience, while perceived clinical efficacy was also a primary determinant among adults, reflecting different emphases on the treatment process itself vs. treatment consequences. Among adult patients and caregivers, improved treatment satisfaction was also a function of reductions in social burden and interference with daily activities (respectively), reflecting concern with the broader psychosocial impact of sensor‐augmented pump therapy on their lives.
