Perceived accuracy in continuous glucose monitoring: understanding the impact on patients.

Abstract

In terms of accuracy and reliability, the technology of real-time (RT) continuous glucose monitoring (CGM) is advancing quickly. Still, current devices are imperfect; as a result, patient complaints and frustrations are not uncommon. How do patients' perceptions of device accuracy affect their experience with RT-CGM? In this article, we argue that patients' satisfaction, or dissatisfaction, with accuracy has a major impact on how much they are likely to trust the device and how confident they may feel in using the information that is displayed. The available data suggest that greater satisfaction with accuracy is linked to better RT-CGM adherence, more confident and aggressive insulin adjustments, improvements in quality of life, reduced reliance on self-monitoring of blood glucose, and--potentially--less alarm fatigue. As the technology continues to mature, RT-CGM will become increasingly accurate and patients' confidence and trust in the available devices will likely grow, leading to greater uptake and more proactive use of RT-CGM.
