Inpatient psych wards are kind of all over the place in the US. However, as someone in the American medical field, I can confirm the grippy socks are definitely a thing.

Generally speaking, inpatient psych facilities here are also filthy, underfunded holding pens run by the dregs of the medical community. Not all, and a lot of people.over here get into medicine specifically for psych but they're outnumbered by the burnt out shitbirds who are just collecting a paycheck. You also get no/the wrong help here and they hold you for a minimum 72 hrs or until you're no longer "a threat to yourself/others". It's often traumatic and life ruining because not only aren't you helped, you're thrown out on the street in debt and possibly out of a job because you missed 3 days of work, making your life measurably worse at the end than it was at the beginning of your admission
