Staff and clients from nontraditional programs for homeless individuals with serious mental illness (HMI) face barriers when trying to transfer client care from street-based services to traditional community mental health centers or organizations (CMHCs). Yet little is known about the extent of those barriers, reported causes, and consequences. In all, 255 mental health supervisors or designees from three programs across the United States that serve HMI (PATH, Health Care for the Homeless, and SafeHavens) responded to a survey that explored issues related to barriers. Results: 92% of the programs reported they experience barriers when trying to transfer client care, 7% reported they did not experience barriers, and 1% were neutral. Health Care for the Homeless programs reported the highest frequency of barriers, with 45% reported experiencing major barriers. Causes of the barriers were linked to socioeconomic-political factors, CMHCs, programs for the homeless, and clients. Serious consequences of those barriers were reported. (Authors)
