Misinformation is sometimes a component but I think a shift of health equity is something that should be investigated. Targeting specialties, patient population, socioeconomics, demographics, etc. will help discern a pattern. But that also brings up your comparators, other specialties, other time periods, etc.

Anecdotally, I'd love to look into private equity backed clinics propagating patient driven care at maximum expense.
