Malpractice law is complex and time consuming. Determining it to be a cause or contributor to a death isn't quite like going "yup, that's pneumonia". Studies are what we use to estimate it, and this one was a big outlier.
Causality itself is a complex philosophical topic. I agree it probably can’t be established.
That’s why death reportings tend to use “died with X”. I understand that there is a sensitivity to ascribe liability or fault. But if someone dies in recovery from a surgery, or worse under anesthesia, that seems like something that could be identified and reported.

We do (for example: https://www.cdc.gov/healthcare-associated-infections/index.h...), but there's significant difference between "malpractice" and "died due to surgical/anesthesia complications". Perfectly administered anesthesia is still risky, which is why we don't give it for, say, mole removal.
