Prison health care in the United States varies from facility to facility. In those that have been accredited by the American Medical Association, health services and personnel may be organized in one of many different ways depending on the size of the institution, the needs of inmates, and the resources in the community. In England, Canada, Poland, and France, the organization of health care for prisoners is mandated by law and directed by a formal governmental agency. The health care system in each country provides different degrees of health coverage; but all employ health care professionals who render uniform medical care to inmates in correctional facilities.
