Honestly, we can pick apart the article based on our views about how T1 and T2 are characterized, but I hope we don't lose sight of the point of the article.
Cost of diabetes care is spiraling out of control.
I think she did a good job, generally, about discussing why those costs are spiraling out of control from a market perspective. If I look at the cost of my care over the last 30 years since I was diagnosed, I've gone from being able to pretty much pay out of pocked for most of my supplies to being completely dependent on insurance for my supplies. I still end up paying more for out of pocked, now, based on my deductible and 20% share of DME.
I don't "need" a pump. I don't "need" analog insulins. Heck, I didn't really "need" flex pens when I was still on MDI. Trying to quantify how much the apex of technological advances in diabetic care (pump) has improved my control over the R and NPH + syringe I used 30 years ago is a difficult thing to do. My best guess tells me maybe 10 - 15% "better" Blood Glucose numbers. That's a difficult number to square with the fact that it would cost me near $1500 more a month out of pocket.
What a pump has done is bought me a much better "quality of life with diabetes", read, "a lifestyle as close to my lifestyle before diabetes without sacrificing complete loss of BG control". Admittedly, even that's difficult to square when you have people like Dr. Bernstein and his proponents basically stating that technology in diabetes care does not have to equate to better BG control and lifestyle choice does not mean sacrificing quality of life.
So, I know the general public has a lot to learn when it comes to completely understanding diabetes and what it's like to be diabetic. Heck, we argue about what that means, exactly, enough in these forums. But let's not drag the author too far over the coals without acknowledging that the article does offer much revelation into how completely screwed up it is to be a diabetic financially speaking.
