I haven't observed it happening in the context of hospitals, but it absolutely is happening to medical education. Brazilian conglomerate Afya was born as a literal PE firm and by now has rolled up many if not most of the private medical schools. It's controlled by some german education conglomerate though.

Their SEC filing mentions they engage in "deregulation advocacy" which is no doubt a hilarious euphemism for lobbying the brazilian government so it relaxes quality standards for medical schools. No doubt they're responsible for much of the enshittification here.
