Limiting any CGM sensor to 80 hours, the current duration of the Omnipod, is an unattractive idea to me. I've used Dexcom CGM's for three years now. Like many other users, I get very good accuracy in the second week of the sensor.
For me, a new sensor takes about 24-36 hours to settle in and get on track with my fingerstick BG's. Even if Omnipod produces a sensor that's accurate immediately, three days plus eight hour (80 hours) sensor life is a step backward, not an improvement.
I wore the Omnipod for five months last year. I had to replace many pods before 80 hours. If they had been integrated with a CGM sensor, that replacement experience would have wasted the value of a lot of sensors. And that's in addition to the early loss of the pod and all the insulin within.
With Omnipod's proposed pod/CGM system, it would take a minimum of 30 pods for a 90-day supply whereas I only need 12 Dexcom sensors for the same 90-day supply. The economics of this plan are moving in the wrong direction.
I appreciate Insulet's effort to make life easier; this plan, however, attempts to do so with unacceptable tradeoffs for me.
