I worked in a 'free', county hospital in the US, Blu. They still try to charge the patient for the cost of their care, although some are covered by healthcare programmes for the indigent and in some states - well, the state I lived in - the state provided vastly subsidised healthcare for children under 16, on a sliding scale w/wages for low income families.
There are on the whole more amenities available, even at that level, b/c of contributions from drgu companies.
Staffing levels also tend to be higher, even at that level.
Also, b/c it is a more litigous society, staff are held more accountable, so the I buzzed and no one came phenomenon appears to happen somewhat less.
Partners were allowed to stay over at county IF the woman had had a traumatic birth experience.
Single rooms were rare at county, and mostly for ladies who might be an infection risk - HIV or HepC +, for example, or who were coming to us from the prison system.
County did have a number of active police officers on patrol as well.
