How people in the United States who work in the mental health field describe inpatient care for the chronically mentally ill.
This is because most seriously ill patients stay in the hospital for less than a month, and return within 6 months for more treatment because of behavior problems, a recurrance of symptoms, medication noncompliance or all of the above.
Rapid readmission is so common nationwide that the revolving door phenomenon is considered a fact of life.

Another good reason not to pick up hitchhikers in the United States.
