They definitely are, but I'm replying to the idea that the drop in life expectancy is because of inefficiencies - the us system has always been pretty inefficient and nothing there has changed in a way that would trigger a decrease in expectancy as far as I know. This current decrease in life expectancy seems to be linked to the ongoing opiod crisis, not a sudden decrease in health delivery efficiency
Life expectancy started to drop in 2015, right as the uninsured rate reached its all-time low. They numbers don’t correlate. It might track to the increased cost of coverage and care, but not the uninsured rate.
