That won't happen. Because hospitals that say residents don't provide any value are just fucking lying.

Source: My partner is an attending physician at a teaching hospital. The residents do a lot of if not most of the work. Yes she's there to guide/supervise/sign off, but they're still doing valuable work (AND the hospital is getting paid more than the residents salary just for having them there).

It's a bluff, any hospital that decides to forego residents is stupid and their competition will happily scoop them up.

And honestly.. there should be some legal consequences for just blatantly lying for propaganda purposes like hospitals do all the time. Fraud? False advertising? I don't know, but it's crazy they can just say provably false stuff that pushes their agenda and 95% of the population that isn't really familiar with the issues in depth just takes it at face value.
