Sixty-two percent of our patients had multiple diagnoses, a subgroup with longer follow-ups, more psychiatric hospitalizations, and longer psychiatric hospitalizations. The prevalence of psychotic disorders was high: organic psychosis (17%), schizophrenia (15%), psychosis not otherwise specified (14%), and schizoaffective disorder (11%), that combined altogether were present in more than half (57%) of our homeless patients.<\/jats:p><\/jats:sec><jats:sec id=\"S1092852921000547_sec4\" sec-type=\"conclusions\"><jats:title>Conclusion<\/jats:title><jats:p>The people living homeless with multiple diagnoses have higher mental health needs and worse determinants of general health.
