I agree, but there are a lot of factors going on to contribute to that number.

For example, about 20% of that number is because someone is finding out for the first time they have T1D [1].

Insulin costs and monitoring costs are also going to be a pretty big contributing factor. CGMs and finger sticks aren't cheap.

IDK how often it happens that ketoacidosis happens when glucose appears to be fine, I assume it's pretty rare.
