Here goes:
The short version is that she’s much happier with the Omnipod. The only reason we ever switched was to get Control IQ.
Here’s the longer version:
I sincerely don’t know why, but her body doesn’t like the Tandem infusion mechanics, regardless of type of infusion set (we tried Autosoft XC, TruSteel, Autosoft 30, and Varisoft). Knock wood, but she’s doing fine (again) with the Omnipod.
We definitely miss Control IQ, but we definitely don’t miss the ridiculously frequent infusion problems and the waste and stress they caused us.
So what other differences are there between Tandem tslim x2 and the Omnipod Dash that have mattered to us? Let’s see:
We really like Omnipod’s display better than Tandem’s. And we really like Dexcom’s display better than Tandem’s, too. So while (until Omnipod gets its integration with Dexcom to market, anyway) using Omnipod means carrying two devices, we prefer the look, feel, and function of both of those devices to Tandem’s. I can elaborate if anyone wants, but basically Omnipod’s PDM is a locked-down cell phone, and Tandem’s pump is clunkier.
She really likes not having to disconnect for showers, the beach, etc.
She really likes not having tubing, and not having to find a place to put her pump where it won’t get snagged or fall or otherwise be in the way.
She likes being able to visually track her sites. Omnipod lets you map where on your body you’re inserting and the date, so you can see on a little pictogram when you last infused where. Not critical, and obviously there are lots of other ways to accomplish the same goal, but it’s a nice feature, and she missed it on the Tandem.
We really like that you can individualize the “insulin on board” duration with Omnipod. Control IQ is set at five hours, period. With Omnipod, you can set it for however fast your particular body metabolizes the particular insulin you’re using. (Check with your endo for advice on where yours needs to be to avoid stacking boluses, but five hours is significantly too long for us.)
But even with everything we went through to get her switched from Omnipod to Tandem only to end up back on Omnipod after all, I’m still not sorry, because the time she had with Control IQ made it far safer, easier, and less stressful for us to learn what her basal rates should be overnight. Having seen Control IQ at work, we were able to adjust her basal rates with far less disruption and far more sleep. When we went back to Omnipod, we took that basal rate schedule with us, and it’s terrific. (I know others have figured out how to tweak their basal rates overnight without the benefit of Control IQ, but it sure was nicer to have it!)
I’m sure there are other things, too, but that’s what I’ve got for now.
Bottom line is where we started: Omnipod works better for us at actually, consistently, physically getting the insulin into her body, and if that’s not happening, the best automated loop technology in the world is no help. So we’re Podders again, and we really can’t wait for Horizon/Dash 5 to come out!
