The authors describe New York City's program to remove seriously mentally ill homeless people from the streets to a public hospital. They report on the 298 patients hospitalized during the first year of this program. Most of the patients were male (66%), single (77%), and from outside of New York City (79%) and claimed a history of previous psychiatric hospitalization (92%) and that they had been homeless for more than 1 year (66%). Most of the patients suffered from schizophrenia (80%) and had additional medical diagnoses (73%). Follow-up contact with the patients 2 years after initiation of the program revealed that 55% of the patients either were living in a community setting or were under institutional care.
