The Bureau of Public Health Facilities is organized as a system of four multi-specialty hospitals that provide acute and chronic hospital medical care to individuals for whom community facilities are not available or access to health care is restricted. The Public Health Hospitals function as an integral part of the Department and contribute to its commitment to maintain, protect and improve the health and well being of citizens of the Commonwealth. Through a combined focus on delivery of health care services to special populations, education and research, the public health hospitals serve as a catalyst for change in the health care system by developing and modeling new treatment programs and responding to emerging health needs.
