Universal health care

Universal health care is health care coverage for all eligible residents of a political region and often covers medical, dental and mental health care. These programs vary in their structure and funding mechanisms. Typically, most costs are met via a single-payer health care system or national health insurance, or else by compulsory regulated pluralist insurance (public, private or mutual) meeting certain regulated standards. Universal health care is implemented in all but one of the wealthy, industrialized countries, with the one exception being the United States. It is also provided in many developing countries and is the trend worldwide.
Implementation
Universal health care is a broad concept that has been implemented in several ways. The common denominator for all such programs is some form of government action aimed at extending access to health care as widely as possible and setting minimum standards. Most implement universal health care through legislation, regulation and taxation. Legislation and regulation direct what care must be provided, to whom, and on what basis. Usually some costs are borne by the patient at the time of consumption but the bulk of costs come from a combination of compulsory insurance and tax revenues. Some programs are paid for entirely out of tax revenues. In some cases, government involvement also includes directly managing the health care system, but many countries use mixed public-private systems to deliver universal health care.
