Dexcom gets a positive review for 10-day use
The March issue of Diabetes Care contains a paper about testing the Dexcom SEVEN for 10-day use with adults with type 1 diabetes.The Dexcom SEVEN continuous glucose monitor has been approved for 7 days of use. I usually get 10 to 11 days of use by restarting the sensor after 7 days have elapsed. Your results may vary, so make sure this works for you before relying on it.
Based on the abstract from the Diabetes Care website, it appears that the results on the 10th day are still fairly accurate. Notice how the difference goes down slightly on the 7th day, showing that the Dexcom is more accurate after it's been in place for a few days.
The median absolute relative difference for CGM versus YSI was 12.6, 11.3, and 14.5% on days 2, 7, and 10, respectively (P = 0.63). CGM performed better on day 10 when compared with self-monitoring of blood glucose as compared with YSI.I expect to see more papers like this before Dexcom applies to the FDA for 10-day use of the sensors. The good news is that this ultimately means less sensors changes will be needed. It also probably means that Dexcom will raises the price of the sensors.
I do hope that before Dexcom takes this move they improve the adhesion of the sensors. Mine usually look like they're falling off by day 9 and they rarely last beyond day 11 because they peel off. Have you been able to get sensors to stay in place for longer? What tricks have you used to make this work?
