To investigate the impact of continuous glucose monitoring (CGM) on health-related quality life (HRQOL), treatment satisfaction (TS) medical resource use, and indirect costs in SWITCH study. was a multicentre, randomized, crossover Patients with type 1 diabetes (n = 153) using subcutaneous insulin infusion (CSII) were randomized to 12 month sensor-On/Off or sensor-Off/On sequence (6 months each treatment), 4-month washout between periods. HRQOL children TS adults measured validated questionnaires. Medical utilization data collected. In adults, significantly higher sensor-On arm, there significant improvements ratings for convenience flexibility. There no clinically differences children's parents' proxy ratings. The incidence severe hypoglycaemia, unscheduled visits, diabetes-related hospitalizations did not differ two arms. Adult patients made fewer telephone consultations during arm; caregivers similar numbers both arms, calls average only 3 min longer arm. Regarding costs, >70 % sensor usage missed school days, compared sensor-Off arm (P 0.0046) but difference days work off. addition CGM CSII resulted better metabolic control without imposing an additional burden patient increased offered potential cost offsets.
