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.

CGM values close enough to dose, yet not reliable enough to skip morning validation. BG path direction is best information to insure person can stay out of trouble
