Background and Aims: Continuous glucose monitoring (CGM) offers a deeper understanding of multiple factors affecting glucose management. We sought to quantify factors patients thought impacted sensor performance or decision making.

Methods: An online survey was reviewed by an Institutional Review Board and offered to people ages 18+ with type 1 (T1D) or type 2 diabetes (T2D) who were former or current CGM users within the T1D Exchange community. Analyses were conducted by T1D Exchange.

Results: 563 current and 42 former CGM users (504 T1D, 101 T2D) responded. 67% current users used Dexcom, 19% Medtronic and 13% Abbott Libre systems. 49% (n = 295/605) had previously temporarily stopped using CGM, of whom 59% (173/295) stopped for ≥1 month. Despite 90% stating majority of sensors were accurate, 42% (251/605) thought accuracy varied from sensor to sensor. 15% stated ≤6/10 sensors could be described as accurate (88/605). 26% (158/605) agreed poor sensors often affected their confidence dosing insulin or ability to make diabetes management decisions (25%, 149/605). 35% (211/605) were concerned about the effect of over‐the‐counter or prescription medications on sensor accuracy, with 43% (259/605) or 32% (195/605) suspecting either pain relief or cold/flu remedies affected sensor accuracy, respectively.
