Abstract
The promotion of continuous glucose monitoring (CGM) to standard of care for type 1 diabetes and insulin-treated type 2 diabetes reflects a robust and wide evidence base for the technology's effectiveness supported by real-world efficacy data. Multiple CGM devices are available worldwide and are marketed, in part, based on accuracy data. In this Viewpoint, we argue that accuracy metrics are no longer a point of difference between CGM devices as almost all exceed an acceptable threshold. We also argue that domains of standardisation, clinical outcomes, and sustainability should now be given primacy as CGM devices seek to be implemented for new indications. These domains are key for the success of the next generation of CGM devices. Additionally, we discuss the need to address inequalities in accessing clinically impactful technologies.
