Health care systems are composed of individuals and organizations that aim to meet the health care needs of target populations. There are a wide variety of health care systems around the world. In some countries, the health care system planning is distributed among market participants, whereas in others planning is made more centrally among governments, trade unions, charities, religious, or other co-ordinated bodies to deliver planned health care services targeted to the populations they serve. |

Health care is the diagnosis, treatment, and prevention of disease, illness, injury, and other physical and mental impairments in humans. Health care is delivered by practitioners in medicine, chiropractic, dentistry, nursing, pharmacy, allied health, and other care providers. The exact configuration of health care systems varies from country to country, but in all cases requires a robust financing mechanism; a well-trained and adequately-paid workforce; reliable information on which to base decisions and policies; and well maintained facilities and logistics to deliver quality medicines and technologies.[1]
Health care industry
The delivery of modern health care depends on an expanding group of trained professionals coming together as an interdisciplinary team.[2][3]
The health-care industry incorporates several sectors that are dedicated to providing health care services and products. According to industry and market classifications, such as the Global Industry Classification Standard and the Industry Classification Benchmark, the health-care industry includes health care equipment and services as well as pharmaceuticals, biotechnology and life sciences. The particular sectors associated with these groups are: biotechnology, diagnostic substances, drug delivery, drug manufacturers, hospitals, medical equipment,instruments, and diagnostic laboratories.
According to the United Nations system the International Standard Industrial Classification, health care generally consists of hospital activities, medical and dental practice activities, and other human health activities. The last class consists of all activities for human health not performed by hospitals, physicians or dentists. This involves activities of, or under the supervision of, nurses, midwives, physiotherapists, scientific or diagnostic laboratories, pathology clinics, home, or other para-medical practitioners in the field of optometry, hydrotherapy, medical massage, yoga therapy, music therapy, occupational therapy, speech therapy, chiropody, homeopathy, chiropractics, acupuncture, etc.[4]
Philosophy
The philosophy of healthcare attempts to synthesize the general meaning of the healthcare industry as an social institution. Through the study of people, processes, politics, and ethics in the healthcare industry, a workable philosophy of healthcare develops. And as a social philosophy, healthcare represents the primary means by which people improve the overall quality of their daily lives. The ultimate purpose of healthcare philosophy is to provide an analytic framework for the collection and analysis of all pertinent data in the healthcare industry, especially for fields like biotechnology, chiropractic, medicine, and nursing.
Research
Top impact factor academic journals in the health care field include Health Affairs and Milbank Quarterly. The New England Journal of Medicine, British Medical Journal, and the Journal of the American Medical Association are more general journals.
Biomedical research (or experimental medicine), in general simply known as medical research, is the basic research, applied research, or translational research conducted to aid the body of knowledge in the field of medicine. Medical research can be divided into two general categories: the evaluation of new treatments for both safety and efficacy in what are termed clinical trials, and all other research that contributes to the development of new treatments. The latter is termed preclinical research if its goal is specifically to elaborate knowledge for the development of new therapeutic strategies. A new paradigm to biomedical research is being termed translational research, which focuses on iterative feedback loops between the basic and clinical research domains to accelerate knowledge translation from the bedside to the bench, and back again.
In terms of pharmaceutical R&D spending, Europe spends a little less than the United States (€22.50bn compared to €27.05bn in 2006) and there is less growth in European R&D spending.[5][6] Pharmaceuticals and other medical devices are the leading high technology exports of Europe and the United States.[6][7] However, the United States dominates the biopharmaceutical field, accounts for the three quarters of the world’s biotechnology revenues and 80% of world R&D spending in biotechnology.[5][6]
World Health Organization
The World Health Organization (WHO) is a specialized United Nations agency which acts as a coordinator and researcher for public health around the world. Established on 7 April 1948, and headquartered in Geneva, Switzerland, the agency inherited the mandate and resources of its predecessor, the Health Organization, which had been an agency of the League of Nations. The WHO's constitution states that its mission "is the attainment by all peoples of the highest possible level of health." Its major task is to combat disease, especially key infectious diseases, and to promote the general health of the peoples of the world. Examples of its work include years of fighting smallpox, which the organization declared in 1979 had been eradicated - the first disease in history to be completely eliminated by deliberate human design. The WHO is nearing success through research activities in developing vaccines against malaria and schistosomiasis.
The WHO is financed by contributions from member states and from donors. In recent years the WHO's work has involved more collaboration, currently around 80 such partnerships, with NGOs and the pharmaceutical industry, as well as with foundations such as the Bill and Melinda Gates Foundation and the Rockefeller Foundation. Research programmes implemented or supported by the WHO include strengthening health systems research,[8] improving access to health research and literature in developing countries,[9] as well as research on neglected tropical diseases,[10] women's reproductive health[11] and other priority areas.
Economics

Health economics is a branch of economics concerned with issues related to scarcity in the allocation of health and health care. Broadly, health economists study the functioning of the health care system and the private and social causes of health-affecting behaviors such as smoking.
A seminal 1963 article by Kenneth Arrow, often credited with giving rise to the health economics as a discipline, drew conceptual distinctions between health and other goals.[12] Factors that distinguish health economics from other areas include extensive government intervention, intractable uncertainty in several dimensions, asymmetric information, and externalities.[13] Governments tend to regulate the health care industry heavily and also tend to be the largest payer within the market. Uncertainty is intrinsic to health, both in patient outcomes and financial concerns. The knowledge gap that exists between a physician and a patient can prevent the patient from accurately describing his symptoms or enable the physician to prescribe unnecessary but profitable services; these imbalances lead to market failures resulting from asymmetric information. Externalities arise frequently when considering health and health care, notably in the context of infectious disease. For example, making an effort to avoid catching a cold, or practicing safer sex, affects people other than the decision maker.
The scope of health economics is neatly encapsulated by Alan William's "plumbing diagram"[14] dividing the discipline into eight distinct topics:
- What influences health? (other than health care)
- What is health and what is its value
- The demand for health care
- The supply of health care
- Micro-economic evaluation at treatment level
- Market equilibrium
- Evaluation at whole system level; and,
- Planning, budgeting and monitoring mechanisms.
Consuming just under 10 percent of gross domestic product of most developed nations, health care can form an enormous part of a country's economy. In 2008, health care consumed an average of 9.0 percent of GDP across the OECD countries[15] with the United States (16.0%), France (11.2%), and Switzerland (10.7%)being the top three spenders.
The United States and Canada account for 48% of world pharmaceutical sales, while Europe, Japan, and all other nations account for 30%, 9%, and 13%, respectively.[6] United States accounts for the three quarters of the world’s biotechnology revenues.
Systems
Social health insurance is where a nation's entire population is eligible for health care coverage, and this coverage and the services provided are regulated. In almost every country, state or municipality with a government health care system a parallel private, and usually for-profit, system is allowed to operate. This is sometimes referred to as two-tier health care or universal health care. The scale, extent, and funding of these private systems is variable.
A traditional view is that improvements in health result from advancements in medical science. The medical model of health focuses on the eradication of illness through diagnosis and effective treatment. In contrast, the social model of health places emphasis on changes that can be made in society and in people's own lifestyles to make the population healthier. It defines illness from the point of view of the individual's functioning within their society rather than by monitoring for changes in biological or physiological signs.[16]

Healthcare reform in the United States |

The United States currently operates under a mixed market health care system. Government sources (federal, state, and local) account for 45% of U.S. health care expenditures.[17] Private sources account for the remainder of costs, with 38% of people receiving health coverage through their employers and 17% arising from other private payment such as private insurance and out-of-pocket co-pays. Opponents of government intervention into the market generally believe that such intervention distorts pricing as government agents would be operating outside of the corporate model and the principles of market discipline; they have less short and medium-term incentives than private agents to make purchases that can generate revenues and avoid bankruptcy. Health system reform in the United States usually focuses around three suggested systems, with proposals currently underway to integrate these systems in various ways to provide a number of health care options. First is single-payer, a term meant to describe a single agency managing a single system, as found in most modernized countries as well as some states and municipalities within the United States. Second are employer or individual insurance mandates, with which the state of Massachusetts has experimented. Finally, there is consumer-driven health, in which systems, consumers, and patients have more control of how they access care. This is argued[by whom?] to provide a greater incentive to find cost-saving health care approaches. Critics of consumer-driven health say that it would benefit the healthy but be insufficient for the chronically sick, much as the current system operates. Over the past thirty years, most of the nation's health care has moved from the second model operating with not-for-profit institutions to the third model operating with for-profit institutions; the greater problems with this approach have been the gradual deregulation of HMOs resulting in fewer of the promised choices for consumers, and the steady increase in consumer costs that have marginalized consumers and burdened states with excessive urgent health care costs that are avoided when consumers actually have adequate access to preventive health care.
A few states have taken serious steps toward universal health care coverage, most notably Minnesota, Massachusetts and Connecticut, with recent examples being the Massachusetts 2006 Health Reform Statute[18] and Connecticut's SustiNet plan to provide quality, affordable health care to state residents.[19]
The Patient Protection and Affordable Care Act (Public Law 111-148) was signed into law by President Barack Obama on March 23, 2010. Along with the Health Care and Education Reconciliation Act of 2010 (signed March 30), the Act is a product of the health care reform efforts of the Democratic 111th Congress and the Obama administration. The law includes health-related provisions to take effect over the next four years, including expanding Medicaid eligibility for people making up to 133% of the federal poverty level (FPL),[20] subsidizing insurance premiums for people making up to 400% of the FPL ($88,000 for family of 4 in 2010) so their maximum "out-of-pocket" payment for annual premiums will be on sliding scale from 2% to 9.8% of income,[21][22] providing incentives for businesses to provide health care benefits, prohibiting denial of coverage and denial of claims based on pre-existing conditions, establishing health insurance exchanges, prohibiting insurers from establishing annual coverage caps, and support for medical research.
Canada
In 1984, the Canada Health Act was passed, which prohibited extra billing by doctors on patients while at the same time billing the public insurance system. In 1999, the prime minister and most premiers reaffirmed in the Social Union Framework Agreement that they are committed to health care that has "comprehensiveness, universality, portability, public administration and accessibility."[23] The system is for the most part publicly funded, yet most of the services are provided by private enterprises or private corporations, although most hospitals are public.
United Kingdom
Each of the Countries of the United Kingdom has a National Health Service that provides public healthcare to all UK permanent residents that is free at the point of need and paid for from general taxation. However private healthcare companies are free to operate alongside the public one. Since Health is a devolved matter, considerable differences are developing between the systems in each of the countries.[24]
Politics
All countries have different policies and plans in relation to health care goals within their societies. The nature of these policies and the politics leading to the decisions taken depend on which country one is in. In the United States, the social and political issues surrounding access to health care have led to vigorous public debate and the almost colloquial use of terms such as health care (medical management of illness), health insurance (reimbursement of health care costs), and public health (the collective state and range of health in a population). In the United States 12% to 16% of the citizens do not have health insurance. State boards and the Department of Health regulate inpatient care to reduce the national health care deficit. To tackle the problems of the perpetually increasing number of uninsured, and costs associated with the US health care system, President Barack Obama says he favors the creation of a universal health care system.[25] However, New York Times opinion columnist Paul Krugman said that Obama's plan would not actually provide universal coverage,[26] and Factcheck.org alleges that Obama's predicted savings were exaggerated.[27] In contrast, the state of Oregon and the city of San Francisco are both examples of governments that adopted universal healthcare systems for strictly fiscal reasons.
Current health care concerns in England revolve around the use of private finance initiatives to build hospitals which it is argued costs taxpayers more in the long run.[28] In Germany and France, concerns are more based on the rising cost of drugs to the governments. In Brazil, an important political issue is the breach of intellectual property rights, or patents, for the domestic manufacture of antiretroviral drugs used in the treatment of HIV/AIDS.
The South African government, whose population sets the record for HIV infections, came under pressure for its refusal to admit there is any connection with AIDS[29] because of the cost it would have involved.
Health care by country
Health care systems are composed of individuals and organizations that aim to meet the health care needs of target populations. There are a wide variety of health care systems around the world. In some countries, the health care system planning is distributed among market participants, whereas in others planning is made more centrally among governments, trade unions, charities, religious, or other co-ordinated bodies to deliver planned health care services targeted to the populations they serve. healthyful life
