This is a good thing. If all causes of death were medically preventable (which would be awesome), by definition preventable medical errors would cause 100% of deaths. (Since they could have prevented it and assuming it's an error not to.) It's simple logic. In other words, the better the standard of medical care, and the better the state of medical science, the higher this number will be, right up to 100% if medical science has an answer to everything. It will never be 100% of zero, as obviously in practice not everything will be done perfextly - but medical error is the delta between theoretical standard of care and actual outcome. The better the theoretical standard, the more deaths must be deemed errors. It can still be far better than if that were not the standard.
