I was only "day hospital" but yes, there are public and private - I would avoid public if possible, from what I hear, but it varies from hospital to hospital, you pretty much have to do your research on each facility - a good place to start is online review sites. Private generally have better care, but again it varies. Staffing levels, staff competence and staff attitudes make a big difference. The place I went was a private, very large and very respected facility, and overall it was pretty decent, staff was very nice and very professional. But it was still a terrifying experience.
