Alarm threshold of interstitial glucose monitors: Consensus on advantages and disadvantages via a Delphi panel

There's a paucity of data on alarms for continuous glucose monitors (CGM) in the literature. The aim of this study was to reach a consensus on the advantages and disadvantages of glucose threshold alarms through a Delphi panel. This method is a decision-support tool to gather expert opinions on a specific topic. These alarms have demonstrated numerous benefits for diabetic patients, allowing them to have better control of their condition, and provide more reassurance to their family and/or caregivers. Moreover, the CGM alarms help patients to improve their daily life during work, school, and sport. However, they can also cause considerable inconvenience. An overwhelming number of alarms per day can embarrass, discourage or lead patients to inappropriate decision-making. In conclusion, the flexibility of being able to opt for these alarms is an important criterion for a tailored and personalised treatment regimen of the patients.
