In my city, the hospital is buying up local clinics, and the service is horrible.
In my part of NJ I see more and more of those clinics; their rise accompanied the closings of our ERs due to the illegal alien invasion (as they defrauded the hospitals with fake names etc. - knowing the hospitals were required to treat them). The clinics are probably a work-around, as they are not ERs so they can ask for paperwork, payment, etc. up front.
The hospitals with closed ERs still function as medical facilities, just without ERs; I suspect everyone going there has an appointment, and the hospital has everything needed to secure payment for services.
