CGM is based on trends - not a single number. The continuous information provides a real-time, dynamic view of one’s glucose to facilitate better management decisions. To optimize the use of Dexcom CGM:
- Patients should be reminded of proper fingerstick technique so they will use their "best" fingersticks for calibrating.
- Patients need to understand that fingersticks are not always accurate, despite their long history. Advise patients to consider taking a second fingerstick when their CGM and first fingerstick do not match.
- Remind patients they are not required to use the Dexcom G5 Mobile to make treatment decisions; they may still use their meter to guide their diabetes management decisions.
