There is mounting evidence supporting the benefits of hybrid closed loop systems for type 1 diabetes (T1D) management. However, published studies lack long-term evaluation of these technologies in ethnically diverse patients including patient-reported outcomes (PROs) assessing lived experiences with these devices.

As part of the Control-IQ Observational (CLIO) study, we evaluated psychosocial outcomes in T1D adults using the Tandem Diabetes Care t:slim X2 insulin pump with Control-IQ technology. Participants completed PRO measures including open-ended items at baseline (pre), 3, 6, and 12 months (post). Wilcox signed rank-test was used to assess differences and qualitative data was analyzed using thematic analysis.

In all, 1306 adult study completers (57.6% female) (White=1084, Hispanic=86, Black=38, Asian=16, Mixed=42) were included in the analysis. Overall, there was a 25.2% improvement in satisfaction with insulin delivery device (IDD) using Control-IQ technology at post (mean=8.83±1.15) vs. pre (i.e., previous IDD) (7.06±2.04) (p<0.001). The Asian cohort reported greater improvement (33.2%) than others. A significant reduction in diabetes impact (33.6%) was noted overall at post (p<0.001) with Hispanic participants reporting greater reduction in diabetes burden (42.8%) than others. For perceived impact of diabetes on quality of life, there was an overall reduction in diabetes impact at post (p<0.001) with Asians showing greater reduction (26.3%) vs. others, specifically in the “freedom to eat as you wish” aspect of life. At post, 71% reported improved sleep quality using Control-IQ technology. Thematic analysis supported these findings highlighting improved diabetes control, quality of life, and ease of use as valuable experiences supporting long-term use of Control-IQ technology. These data demonstrate substantial and sustained psychosocial improvements using Control-IQ technology in diverse ethnic cohorts with type 1 diabetes.
