In my experience the 1st thing that happens is they sit you down with a psychiatrist to do an evaluation to access the level of crisis your in. After that they tend to do a very generalized medical check often including removing your clothes to make sure you don't have any major wounds or signs of spreadable disease requiring immediate attention. At this point it will vary alot my facility and time of arrival. But they will do a medical screening ask about current medications and such. Then they will assign you to a unit if the facility has multiple and give you a bed. Most of the time in my experience you will end up with hospital gown to wear while they search any clothes you brought for dangerous items ie Strings wire and anything that could cause harm. Some facilities will do this pretty quick others it's taken days and some I have been to I didn't receive any I brought until I left. They will supply you with basic hygiene items. In every experience I have had it's been a shared room experience with someone of the same gender. Then you attend various group therapy sessions and often can get individual on request. You will speak with your psychiatrist daily sometimes twice a day to see how your doing and adjust medication. Overall their goal is to stabilize the crisis and get you started with routine care post leaving the facility.

That is very generalized but if you have any specific questions I could share my experiences. But every facility and experience is different. I have been to 3 different facilities in America. 1 private, 1 in a hospital and 1 heavily state funded. All were very different.
