Right on about Halstead, dude was crazy. It's a ridiculous model that definitely contributes to the rate of errors and burnout. So the obvious solution is easing the burden of care currently on US resident physicians, which will require hospital systems either to supplement heavily with midlevel practitioners or take on more residents. Midlevels still have to get physician oversight in most states, so even a solution pursuing strict midlevel expansion will require more residency spots. And after residency positions are expanded, there has to be some sort of incentive to ensure that the new attending doctors get to areas where they are needed, i.e. poor and rural communities. This will be a multi-decade transition process, and only tackles a part of the train wreck that is the American healthcare system.
