Health care (sometimes shortened to "healthcare") is the prevention, treatment, and management of illness and the preservation of mental and physical well being through the services offered by the medical, nursing, and allied health professions. According to the World Health Organisation, health care embraces all the goods and services designed to promote health, including “preventive, curative and palliative interventions, whether directed to individuals or to populations”.[1] The organised provision of such services may constitute a health care system. This can include a specific governmental organisation such as, in the UK, the National Health Service or a cooperation across the National Health Service and Social Services as in Shared Care. Before the term "health care" became popular, English-speakers referred to medicine or to the health sector and spoke of the treatment and prevention of illness and disease.
In most developed countries and many developing countries health care is provided to everyone regardless of their ability to pay. The National Health Service in the United Kingdom was the world's first universal health care system provided by government. It was established in 1948 by Clement Atlee's Labour government. Alternatively, compulsory government funded health insurance with nominal fees can be provided, as in France which has the best health system in the world, or Italy which has the second best according to the World Health Organisation.[2] Other examples are Medicare in Australia, established in the 1970s by the Labour government, and by the same name Medicare in Canada, established between 1966 and 1984. Universal health care contrasts to the systems like health care in the United States or South Africa, though South Africa is one of the many countries attempting health care reform.
Health care industry
The health care industry is one of the world's largest and fastest-growing industries.[4] Consuming over 10 percent of gross domestic product of most developed nations, health care can form an enormous part of a country's economy. In 2003, health care costs paid to hospitals, physicians, nursing homes, diagnostic laboratories, pharmacies, medical device manufacturers and other components of the health care system, consumed 15.3 percent[5] of the GDP of the United States, the largest of any country in the world. For United States, the health share of gross domestic product (GDP) is expected to hold steady in 2006 before resuming its historical upward trend, reaching 19.6 percent of GDP by 2016. [6] In 2001, for the OECD countries the average was 8.4 percent [7] with the United States (13.9%), Switzerland (10.9%), and Germany (10.7%) being the top three.
According to Health Affairs, USD$7,498 will be spent on every woman, man and child in the United States in 2007, 20 percent of all spending. Costs are projected to increase to $12,782 by 2016.[8] The healthcare industry includes the delivery of health services by health care providers. Usually such services receive payment from the patient or from the patient's insurance company; although they may be government-financed (such as the National Health Service in the United Kingdom) or delivered by charities or volunteers, particularly in poorer countries. There are many ways of providing healthcare in the modern world. The most common way is face-to-face delivery, where care provider and patient see each other 'in the flesh'. This is what occurs in general medicine in most countries. However, healthcare is not always face-to-face; with modern telecommunications technology, in absentia health care is becoming more common. This could be when practitioner and patient communicate over the phone, video conferencing, the internet, email, text messages, or any other form of non-face-to-face communication.
