In the D-OC, it has become easy to see that the Dexcom seems to be the CGM system of choice. I have the MiniMed system. When I first picked my pump, CGMS was so new that there wasn't even an integrated system yet. But it was coming. Within a few months it was to be released, so I went with it immediately in hopes that I'd be one of the first on CGMS. And I was lucky. Not only was I one of the first to be on MiniMed CGMS, MiniMed was extremely helpful in navigating the insurance system and I was approved the first time through (extremely rare at the time...and even now).
From the very beginning I have had good experience with my MiniMed CGMS. Each time the insurance had demanded reverification, MiniMed has been right on top of things. I have had great customer service experience with them.
On top of that, MiniMed CGMS has even saved my life a couple of times. I never had the various problems with the accuracy that most people have. Occasionally, I'll have a crappy sensor, but no where near as often as I've heard some people talk about. My accuracy is fairly good for the most part. Not perfect, but what CGMS system does?
My problems, for the most part, have been minor. I'd prefer louder alarms (for nighttime). And I wanted more predictor alarms. That's why, when I was searching for a new pump, and I found out about the Revel from MiniMed, I went with that one right away.
But then I was disappointed in the new system for alarming. I wrote a pretty detailed post when I had a scary night. With the changes in the alarming, the insulin pump didn't wake me up for WAY too long.
While I'm still pretty satisfied with the overall accuracy, and I don't have site problems (i.e. irritation, infection, etc.) for the most part, I have begun to wonder about the Dex and some of the benefits in changing systems.
This is where I need help. I need some of my fellow D-OC members to help me answer some questions. To see if its worth the time and effort (and fighting the insurance company) to try to get a new system. I don't want to leave what I know is okay, if I'm not going to get way better. Does that make sense?
1.) Do the sensor and the receiver loose contact with each other often? I have noticed that if I don't wear my sensor and pump on the same side of my body, it will lose contact. Also, what about under covers at night. I often sleep with 2 or 3 blankets. Will this be an issue with the sensor and receiver communicating (I wear my CGMS on my upper thigh currently, so it would be completely covered up).
2.) Does the Dex give prediction alerts. i.e. Do you get alerts for rapidly rising or falling blood sugars, and do you get alerts when you are approaching your high or low limits (the MiniMed does this on the Revel).
3.) What happens if you don't turn the receiver off after an alert? Does it keep beeping? Does it beep louder? Does it vibrate?
4.) Do you have problems with leaving it places? One of the reasons I liked the MiniMed system so much is that its integrated and there's no chance of me leaving it somewhere. I tend to be a forgetful person. Not always. But I have been known to run off and leave my meter or my cell phone at home occasionally.
5.) How is the accuracy? If you've used both the MiniMed and the Dex, which do you find is more accurate? If you've only used Dex, are you satisfied with the accuracy?
6.) How difficult was it to get approved? Insurance. Can't live with it, can't live without it. :/
