The National Institute for Health and Care Excellence (NICE) is an executive non-departmental public body of the Department of Health in the United Kingdom, which publishes guidelines in four areas:
  • the use of health technologies within the National Health Service (NHS) (such as the use of new and existing medicines, treatments and procedures)
  • clinical practice (guidance on the appropriate treatment and care of people with specific diseases and conditions)
  • guidance for public sector workers on health promotion and ill-health avoidance
  • guidance for social care services and users.
These appraisals are based primarily on evaluations of efficacy and cost-effectiveness in various circumstances. 

It serves both the English NHS and the Welsh NHS. It was set up as the National Institute for Clinical Excellence in 1999, and on 1 April 2005 joined with the Health Development Agency to become the new National Institute for Health and Clinical Excellence (still abbreviated as NICE). Following the Health and Social Care Act 2012, NICE was renamed the National Institute for Health and Care Excellence on 1 April 2013 reflecting its new responsibilities for social care, and changed from a special health authority to an Executive Non-Departmental Public Body (NDPB).

NICE was established in an attempt to end the so-called postcode lottery of healthcare in England and Wales, where treatments that were available depended upon the NHS Health Authority area in which the patient happened to live, but it has since acquired a high reputation internationally as a role model for the development of clinical guidelines. One aspect of this is the explicit determination of cost–benefit boundaries for certain technologies that it assesses. NICE also plays an important role in pioneering technology assessment in other healthcare systems through NICE International, established in May 2008 to help cultivate links with foreign governments.

Policy history

The notion of an Institute to determine the clinical effectiveness of interventions first emerged at the end of John Major's Conservative Government as moves elsewhere were being made to set professionally agreed standards for clinical care. In 1996, the UK National Screening Committee (NSC) had been established by Sir Kenneth Calman and Muir Gray (now Sir Muir Gray) by the Policy Team led by Dr Tim Riley and latterly Sir Charles Nightingale for the Department of Health. The NSC aimed to ensure that evidence-based medicine informed policy making on what national screening programmes were approved for funding and what quality assurance mechanisms should be in place. This was a timely action as screening quality in breast cancer screening services came under question at Exeter in 1997 and followed in the wake of the 1995 Calman-Hine Report.

The idea of what was originally termed a National Institute for Clinical Excellence took root when Labour came to power in 1997. Frank Dobson became Secretary of State and was supported by a team of Ministers keen on introducing clinical and health outcome measures to achieve improvements in the quality and delivery of care. The team included Alan Milburn, Baroness Margaret Jay, and Tessa Jowell. The name and mission was agreed in a meeting between the Ministerial team, Dr Tim Riley and Dr Felicity Harvey shortly after the election and it was agreed that NICE should be described in the first policy white paper, The New NHS: Modern, Dependable 1997. Riley led the team that developed the policy for NICE and which managed the legislation through Parliament in addition to formalising the new institute as a Special Health Authority. Riley joined Sir Michael Rawlins (the then recently appointed Chair of NICE) at the Health Select Committee in February 1999 where questions were raised as to whether NICE was just a means to "ration" healthcare. Sir Michael Rawlins presented a compelling case that positioned NICE as a standards setting body first and foremost. However, the reality was that although NICE was principally aimed at aligning professional standards through clinical guidelines and audit, the acceptability of drugs, devices and technological interventions in defining those standards, could not be ignored and so the concept of a "fourth hurdle" for drugs accessing the NHS market was invoked. This controversial policy shift meant that NICE was critical for decisions on drug reimbursement. Indeed, the first drug appraisal by NICE was on the drug Relenza which was turned down amidst criticisms from Glaxo-Wellcome that the appraisal had been fast tracked. Later, this policy development whereby the criteria for decision making, the role of costs, and the degree to which decisions of NICE and the secretary of state would be binding on clinicians was analysed by Andrew Dillon, Trevor Gibbs, Tim Riley, and Trevor A. Sheldon.

Technology appraisals

Since January 2005, the NHS in England and Wales has been legally obliged to provide funding for medicines and treatments recommended by NICE's technology appraisal board. This was at least in part as a result of well-publicised postcode lottery anomalies in which certain less-common treatments were funded in some parts of the UK but not in others due to local decision making in the NHS. 

Before an appraisal, the Advisory Committee on Topic Selection (ACTS) draws up a list of potential topics of clinical significance for appraisal. The Secretary of State for Health or the Welsh Assembly must then refer any technology so that the appraisal process can be formally initiated. Once this has been done NICE works with the Department of Health to draw up the scope of the appraisal.

NICE then invites consultee and commentator organisations to take part in the appraisal. A consultee organisation would include patient groups, organisations representing health care professionals and the manufacturers of the product undergoing appraisal. Consultees submit evidence during the appraisal and comment on the appraisal documents. Commentator organisations include the manufacturers of products to which the product undergoing appraisal is being compared. They comment on the documents that have been submitted and drawn up but do not actually submit information themselves. 

An independent academic centre then draws together and analyses all of the published information on the technology under appraisal and prepares an assessment report. This can be commented on by the Consultees and Commentators. Comments are then taken into account and changes made to the assessment report to produce an evaluation report. An independent Appraisal Committee then looks at the evaluation report, hears spoken testimony from clinical experts, patient groups and carers. They take their testimony into account and draw up a document known as the 'appraisal consultation document'. This is sent to all consultees and commentators who are then able to make further comments. Once these comments have been taken into account the final document is drawn up called the 'final appraisal determination'. This is submitted to NICE for approval. 

The process aims to be fully independent of government and lobbying power, basing decisions fully on clinical and cost-effectiveness. There have been concerns that lobbying by pharmaceutical companies to mobilise media attention and influence public opinion are attempts to influence the decision-making process. A fast-track assessment system has been introduced to reach decisions where there is most pressure for a conclusion.

Clinical guidelines

NICE carries out assessments of the most appropriate treatment regimes for different diseases. This must take into account both desired medical outcomes (i.e. the best possible result for the patient) and also economic arguments regarding differing treatments.

NICE has set up several National Collaborating Centres bringing together expertise from the royal medical colleges, professional bodies and patient/carer organisations which draw up the guidelines. The centres are the National Collaborating Centre for Cancer, the National Clinical Guideline Centre, the National Collaborating Centre for Women and Children´s Health, and the National Collaborating Centre for Mental Health.

The National Collaborating Centre appoints a Guideline Development Group whose job it is to work on the development of the clinical guideline. This group consists of medical professionals, representatives of patient and carer groups and technical experts. They work together to assess the evidence for the guideline topic (e.g. clinical trials of competing products) before preparing a draft guideline. There are then two consultation periods in which stakeholder organisations are able to comment on the draft guideline. After the second consultation period, an independent Guideline Review Panel reviews the guideline and stakeholder comments and ensures that these comments have been taken into account. The Guideline Development Group then finalises the recommendations and the National Collaboration Centre produces the final guideline. This is submitted to NICE to formally approve the guideline and issue the guidance to the NHS. To date NICE has produced more than 200 different guidelines.

In October 2014 Andy Burnham said that a Labour government could reduce variation in access to drugs and procedures by making it mandatory for commissioners to follow NICE clinical guidelines. "We need to look at how you strengthen NICE. Where they have said something is effective and affordable, on what basis does a local commissioner withhold that from somebody? I’m not comfortable with that. I don’t support that."

NICE has a service called Clinical Knowledge Summaries (CKS) which provides primary care practitioners with a readily accessible summary of the current evidence base and practical guidance.

Social care guidance

Under the Health and Social Care Act 2012, NICE was given responsibility for developing guidance and quality standards for social care, using an evidence-based model. This is being delivered by the NICE Collaborating Centre for Social Care (NCCSC), which is hosted by the Social Care Institute for Excellence (SCIE) and 4 partner organisations - Research in Practice, Research in Practice for Adults, Personal Social Services Research Unit and the EPPI-Centre.

NICE receives referrals for social care guidance from the Department of Health and the Department for Education, and commission the guidance from the NCCSC. NICE, along with the NCCSC, carries out a scoping exercise with a scoping group and with input from key stakeholders, at both a workshop and a public consultation, to ensure the guidance to be produced is focused and achievable. A chairperson and members of the Guidance Development Group are appointed, and pose review questions which will enable systematic evidence reviews to take place, thus delivering the guidance and subsequent recommendations. Service user and carer involvement takes place throughout, as well as public consultation on the draft guidance.

The Guidance Development Group then finalises the recommendations and the NCCSC produces the final guideline. This is submitted to NICE for formal approval and publication. The entire process from pre-scoping to publication takes approximately 24 months. The guidance is then available to NICE standing committees to develop a quality standard on the topic. The quality standard is developed using the guidance and other accredited sources, to produce high-level concise statements that can be used for quality improvement by social care providers and commissioners, as well as setting out what service users and carers can expect of high quality social care services.

The NCCSC is unique within NICE, in that it is the only collaborating centre to have responsibility for the adoption and dissemination support for guidance and quality standards in the social care arena. Drawing on the expertise of SCIE and their partners within the sector, each of the guidance products and quality standards have a needs assessment carried out to determine the requirements for tools to help embed the guidance and quality standards within the sector. These can include tailored versions of guidance for specific audiences, costing and commissioning tools and even training and learning packages.

As of August 2013, NICE and the NCCSC had scheduled guidance delivery for five topics: domiciliary care, older adults with long-term conditions, transition between health and social care settings, transition from children's to adults' services and child abuse and neglect.

Cost–effectiveness

As with any system financing health care, the NHS has a limited budget and a vast number of potential spending options. Choices must be made as to how this limited budget is spent. Economic evaluations are carried out within a health technology assessment framework to compare the cost-effectiveness of alternative activities and to consider the opportunity cost associated with their decisions. By choosing to spend the finite NHS budget upon those treatment options that provide the most efficient results, society can ensure it does not lose out on possible health gains through spending on inefficient treatments and neglecting those that are more efficient.

NICE attempts to assess the cost–effectiveness of potential expenditures within the NHS to assess whether or not they represent 'better value' for money than treatments that would be neglected if the expenditure took place. It assesses the cost–effectiveness of new treatments by analysing the cost and benefit of the proposed treatment relative to the next best treatment that is currently in use.

Quality-adjusted life years

NICE guidance supports the use of quality-adjusted life years (QALY) as the primary outcome for quantifying the expected health benefits associated with a given treatment regime. By comparing the present value (see discounting) of expected QALY flows with and without treatment, or relative to another treatment, the net/relative health benefit derived from such a treatment can be derived. When combined with the relative cost of treatment, this information can be used to estimate an incremental cost-effectiveness ratio (ICER), which is considered in relation to NICE's threshold willingness-to-pay value.

As a guideline rule, NICE accepts as cost-effective those interventions with an incremental cost-effectiveness ratio of less than £20,000 per QALY and that there should be increasingly strong reasons for accepting as cost-effective interventions with an incremental cost-effectiveness ratio of over a threshold of £30,000 per QALY.

Over the years, there has been great controversy as to what value this threshold should be set at. Initially, there was no fixed number. But the appraisal teams created a consensus amount of about £30,000. However, in November 2008 Alan Johnson, the then Secretary of State, announced that for end-of-life cancer drugs the threshold could be increased above £30,000. 

The first drug to go through the new process was Lenalidomide, whose ICER was £43,800.

Cost per quality-adjusted life year gained

The following example from NICE explains the QALY principle and the application of the cost per QALY calculation.

A patient has a life-threatening condition and is expected to live on average for 1 year receiving the current best treatment which costs the NHS £3,000. A new drug becomes available that will extend the life of the patient by three months and improve his or her quality of life, but the new treatment will cost the NHS more than three times as much at £10,000. Patients score their perceived quality of life on a scale from 0 to 1 with 0 being worst possible health and 1 being best possible health. On the standard treatment, quality of life is rated with a score of 0.4 but it improves to 0.6 with the new treatment. Patients on the new treatment on average live an extra 3 months, so 1.25 years in total. The quality of life gained is the product of life span and quality rating with the new treatment less the same calculation for the old treatment, i.e. (1.25 x 0.6) less (1.0 x 0.4) = 0.35 QALY. The marginal cost of the new treatment to deliver this extra gain is £7,000 so the cost per quality life year gained is £7000/0.35 or £20,000. This is within the £20,000-£30,000 that is suggested by NICE to be the limit for drugs to be cost-effective.

If the patient was expected to live only one month extra and instead of three then NICE would issue a recommendation not to fund. The patient's Primary Care Trust could still decide to fund the new treatment, but if not, the patient would then have two choices. He or she could opt to take the free NHS standard treatment, or he or she may decide to pay out of pocket to obtain the benefit of the new treatment from a different health care provider. If the person has a private health insurance policy the person could check to see whether the private insurance provider will fund the new treatment. About 8% of the population has some private health insurance from an employer or trade association and 2% pay from their own resources.

Basis of recommendations

Theoretically, it might be possible to draw up a table of all possible treatments sorted by increasing the cost per quality-adjusted life year gained. Those treatments with lowest cost per quality-adjusted life year gained would appear at the top of the table and deliver the most benefit per value spent and would be easiest to justify funding for. Those where the delivered benefit is low and the cost is high would appear at the bottom of the list. Decision makers would, theoretically, work down the table, adopting services that are the most cost effective. The point at which the NHS budget is exhausted would reveal the shadow price, the threshold lying between the CQG gained of the last service that is funded and that of the next most cost effective service that is not funded.

In practice this exercise is not done, but an assumed shadow price has been used by NICE for many years in its assessments to determine which treatments the NHS should and should not fund. NICE states that for drugs the cost per QALY should not normally exceed £30,000 but that there is not a hard threshold, though research has shown that any threshold is "somewhat higher" than being in the range £35,000 - £40,000.

The House of Commons Health Select Committee, in its report on NICE, stated in 2008 that "the (...) cost-per-QALY it uses to decide whether a treatment is cost-effective is of serious concern. The threshold it employs is not based on empirical research and is not directly related to the NHS budget, nor is it at the same level as that used by Primary Care Trusts (PCTs) in providing treatments not assessed by NICE, which tends to be lower. Some witnesses, including patient organisations and pharmaceutical companies, thought NICE should be more generous in the cost per QALY threshold it uses, and should approve more products. On the other hand, some PCTs struggle to implement NICE guidance at the current threshold and other witnesses argued that a lower level should be used. However, there are many uncertainties about the thresholds used by PCTs." It went on to recommend that "an independent body should determine the threshold used when making judgements of the value of drugs to the NHS."

Criticism

The work that NICE is involved in attracts the attention of many groups, including doctors, the pharmaceutical industry, and patients. NICE is often associated with controversy, because the need to make decisions at a national level can conflict with what is (or is believed to be) in the best interests of an individual patient. 

Approved cancer drugs and treatments such as radiotherapy and chemotherapy are funded by the NHS without any financial contribution being taken from the patient. Where NICE has approved a treatment, the NHS must fund it. But not all treatments have been assessed by NICE and these treatments are usually dependent on local NHS decision making. In the case of cancer the Cancer Drugs Fund was set up in 2011 after complaints about NICE decisions on new and expensive cancer drugs with limited benefits. Treatment for fertility problems are approved but not always funded by clinical commissioning groups and they may cap the number of rounds.

NICE has been criticised for being too slow to reach decisions. On one occasion, the Royal National Institute of Blind People said it was outraged over its delayed decision for further guidance regarding two drugs for macular degeneration that are already approved for use in the NHS. However the Department of Health said that it had 'made it clear to PCTs that funding for treatments should not be withheld simply because guidance from NICE is unavailable'.

Some of the more controversial NICE decisions have concerned donepezil, galantamine, rivastigmine (review) and memantine for the treatment of Alzheimer's disease and bevacizumab, sorafenib, sunitinib and temsirolimus for renal cell carcinoma. All these are drugs with a high cost per treatment and NICE has either rejected or restricted their use in the NHS on the grounds that they are not cost-effective. 

A Conservative shadow minister once criticized NICE for spending more on communications than assessments. In its defence, NICE said the majority of its communications budget was spent informing doctors about which drugs had been approved and new guidelines for treatments and that the actual cost of assessing new drugs for the NHS includes money spent on NICE's behalf by the Department of Health. When these were added to NICE's own costs, the total cost of the technology appraisal programme far outstrips the cost of NICE communications.

A report from the University of York Centre for Health Economics written by Karl Claxton in February 2015 suggested that the maximum threshold, currently around £30,000 a year, for judging a medicine cost-effective should be more than halved. They found that any intervention costing more than £13,000 per Quality-adjusted life year risked causing more harm than good by denying cost effective treatment to other patients.

The institute's approach to the introduction of new oral therapy for Hepatitis C has been criticised. Sofosbuvir was approved in 2015. It costs about £30,000 for 12 weeks treatment. NHS England established 22 Operational Delivery Networks to roll out delivery and proposes to fund 10,000 courses of treatment in 2016-17. Each has been given a “run rate” of how many patients they are allowed to treat. This is the NHS’ single biggest new treatment investment this year. In the North East London network patients with cirrhosis or fibrosis go to the front of the queue and three new patients at the Grahame Hayton Unit at the Royal London Hospital start treatment each month. Those without such complications may faced considerable delays before they start treatment.

Socialized medicine

From Wikipedia, the free encyclopedia

Socialized medicine is a term used in the United States to describe and discuss systems of universal health care: medical and hospital care for all by means of government regulation of health care and subsidies derived from taxation. Because of historically negative associations with socialism in American culture, the term is usually used pejoratively in American political discourse. The term was first widely used in the United States by advocates of the American Medical Association in opposition to President Harry S. Truman's 1947 health-care initiative.

Background

The original meaning was confined to systems in which the government operates health care facilities and employs health care professionals. This narrower usage would apply to the British National Health Service hospital trusts and health systems that operate in other countries as diverse as Finland, Spain, Israel, and Cuba. The United States Veterans Health Administration and the medical departments of the U.S. Army, Navy, and Air Force, would also fall under this narrow definition. When used in that way, the narrow definition permits a clear distinction from single payer health insurance systems, in which the government finances health care but is not involved in care delivery.

More recently, American conservative critics of health care reform have attempted to broaden the term by applying it to any publicly funded system. Canada's Medicare system and most of the UK's NHS general practitioner and dental services, which are systems where health care is delivered by private business with partial or total government funding, fit the broader definition, as do the health care systems of most of Western Europe. In the United States, Medicare, Medicaid, and the US military's TRICARE fall under that definition. In specific regard to military benefits of a (currently) volunteer military, such care is an owed benefit to a specific group as part of an economic exchange, which muddies the definition yet further. 

Most industrialized countries and many developing countries operate some form of publicly funded health care with universal coverage as the goal. According to the Institute of Medicine and others, the United States is the only wealthy, industrialized nation that does not provide universal health care.

Jonathan Oberlander, a professor of health policy at the University of North Carolina, maintains that the term is merely a political pejorative that has been defined to mean different levels of government involvement in health care, depending on what the speaker was arguing against at the time.

The term is often used by conservatives in the U.S. to imply that the privately run health care system would become controlled by the government, thereby associating it with socialism, which has negative connotations to some people in American political culture. As such, its usage is controversial, and at odds with the views of conservatives in other countries prepared to defend socialized medicine such as Margaret Thatcher.

History of term

When the term "socialized medicine" first appeared in the United States in the early 20th century, it bore no negative connotations. Otto P. Geier, chairman of the Preventive Medicine Section of the American Medical Association, was quoted in The New York Times in 1917 as praising socialized medicine as a way to "discover disease in its incipiency," help end "venereal diseases, alcoholism, tuberculosis," and "make a fundamental contribution to social welfare." However, by the 1930s, the term socialized medicine was routinely used negatively by conservative opponents of publicly funded health care who wished to imply it represented socialism, and by extension, communism. Universal health care and national health insurance were first proposed by U.S. President Theodore Roosevelt. President Franklin D. Roosevelt later championed it, as did Harry S. Truman as part of his Fair Deal and many others. Truman announced before describing his proposal that: "This is not socialized medicine".

Government involvement in health care was ardently opposed by the AMA, which distributed posters to doctors with slogans such as "Socialized medicine ... will undermine the democratic form of government." According to T.R. Reid (The Healing of America, 2009):
The term ["socialized medicine"] was popularized by the public relations firm Whitaker and Baxter working for the American Medical Association in 1947 to disparage President Truman's proposal for a national health care system. It was a label, at the dawn of the cold war, meant to suggest that anybody advocating universal access to health care must be a communist. And the phrase has retained its political power for six decades.
The AMA conducted a nationwide campaign called Operation Coffee Cup during the late 1950s and early 1960s in opposition to the Democrats' plans to extend Social Security to include health insurance for the elderly, later known as Medicare. As part of the plan, doctors' wives would organize coffee meetings in an attempt to convince acquaintances to write letters to Congress opposing the program. In 1961, Ronald Reagan recorded a disc entitled Ronald Reagan Speaks Out Against Socialized Medicine warning its audience the "dangers" that socialized medicine could bring. The recording was widely played at Operation Coffee Cup meetings. Other pressure groups began to extend the definition from state managed health care to any form of state finance in health care. President Dwight Eisenhower opposed plans to expand government role in healthcare during his time in office.

In more recent times, the term was brought up again by Republicans in the 2008 U.S. presidential election. In July 2007, one month after the release of Michael Moore's film Sicko, Rudy Giuliani, the front-runner for the 2008 Republican presidential nomination, attacked the health care plans of Democratic presidential candidates as socialized medicine that was European and socialist, Giuliani claimed that he had a better chance of surviving prostate cancer in the US than he would have had in England and went on to repeat the claim in campaign speeches for three months before making them in a radio advertisement. After the radio ad began running, the use of the statistic was widely criticized by FactCheck.org, PolitiFact.com, by The Washington Post, and others who consulted leading cancer experts and found that Giuliani's cancer survival statistics to be false, misleading or "flat wrong," the numbers having been reported to have been obtained from an opinion article by Giuliani health care advisor David Gratzer, a Canadian psychiatrist in the Manhattan Institute's City Journal where Gratzer was a senior fellow. The Times reported that the British Health Secretary pleaded with Giuliani to stop using the NHS as a political football in American presidential politics. The article reported that not only the figures were five years out of date and wrong but also that US health experts disputed both the accuracy of Giuliani's figures and questioned whether it was fair to make a direct comparison. The St. Petersburg Times said that Giuliani's tactic of "injecting a little fear" exploited cancer, which was "apparently not beneath a survivor with presidential aspirations." Giuliani's repetition of the error even after it had been pointed out to him earned him more criticism and was awarded four "Pinnochios" by the Washington Post for recidivism.

Health care professionals have tended to avoid the term because of its pejorative nature, but if they use it, they do not include publicly funded private medical schemes such as Medicaid. Opponents of state involvement in health care tend to use the looser definition.

The term is widely used by the American media and pressure groups. Some have even stretched use of the term to cover any regulation of health care, publicly financed or not. The term is often used to criticize publicly provided health care outside the US, but rarely to describe similar health care programs there, such as the Veterans Administration clinics and hospitals, military health care, or the single payer programs such as Medicaid and Medicare. Many conservatives use the term to evoke negative sentiment toward health care reform that would involve increasing government involvement in the US health care system. 

Medical staff, academics and most professionals in the field and international bodies such as the World Health Organization tend to avoid use of the term. Outside the US, the terms most commonly used are universal health care or public health care. According to health economist Uwe Reinhardt, "strictly speaking, the term 'socialized medicine' should be reserved for health systems in which the government operates the production of health care and provides its financing." Still others say the term has no meaning at all.

In more recent times, the term has gained a more positive reappraisal. Documentary movie maker Michael Moore in his documentary Sicko pointed out that Americans do not talk about public libraries or the police or the fire department as being "socialized" and do not have negative opinions of these. Media personalities such as Oprah Winfrey have also weighed in behind the concept of public involvement in healthcare. A 2008 poll indicates that Americans are sharply divided when asked about their views of the expression socialized medicine, with a large percentage of Democrats holding favorable views, while a large percentage of Republicans holding unfavorable views. Independents tend to somewhat favor it.

History in United States

The Veterans Health Administration, the Military Health System, and the Indian Health Service are examples of socialized medicine in the stricter sense of government administered care, but they are for limited populations.

Medicare and Medicaid are forms of publicly funded health care, which fits the looser definition of socialized medicine. Part B coverage (Medical) requires a monthly premium of $96.40 (and possibly higher) and the first $135 of costs per year also fall to the senior, not the government.

A poll released in February 2008, conducted by the Harvard School of Public Health and Harris Interactive, indicated that Americans are currently divided in their opinions of socialized medicine, and this split correlates strongly with their political party affiliation.

Two thirds of those polled said they understood the term "socialized medicine" very well or somewhat well. When offered descriptions of what such a system could mean, strong majorities believed that it means "the government makes sure everyone has health insurance" (79%) and "the government pays most of the cost of health care" (73%). One third (32%) felt that socialized medicine is a system in which "the government tells doctors what to do." The poll showed "striking differences" by party affiliation. Among Republicans polled, 70% said that socialized medicine would be worse than the current system. The same percentage of Democrats (70%) said that a socialized medical system would be better than the current system. Independents were more evenly split, with 43% saying socialized medicine would be better and 38% worse.

According to Robert J. Blendon, professor of health policy and political analysis at the Harvard School of Public Health, "The phrase 'socialized medicine' really resonates as a pejorative with Republicans. However, that so many Democrats believe that socialized medicine would be an improvement is an indication of their dissatisfaction with our current system." Physicians' opinions have become more favorable toward "socialized medicine."

A 2008 survey of doctors, published in Annals of Internal Medicine, shows that physicians support universal health care and national health insurance by almost 2 to 1.

Political controversies in the United States

Although the marginal scope of free or subsidized medicine provided is much discussed within the political body in most countries with socialized health care systems, there is little or no evidence of strong public pressure for the removal of subsidies or the privatization of health care in those countries. The political distaste for government involvement in health care in the U.S. is a unique counter to the trend found in other developed countries.

In the United States, neither of the main parties favors a socialized system that puts the government in charge of hospitals or doctors, but they do have different approaches to financing and access. Democrats tend to be favorably inclined towards reform that involves more government control over health care financing and citizens' right of access to health care. Republicans are broadly in favor of the status quo, or a reform of the financing system that gives more power to the citizen, often through tax credits.

Supporters of government involvement in health care argue that government involvement ensures access, quality, and addresses market failures specific to the health care markets. When the government covers the cost of health care, there is no need for individuals or their employers to pay for private insurance. 

Opponents also claim that the absence of a market mechanism may slow innovation in treatment and research.

Both sides have also looked to more philosophical arguments, debating whether people have a fundamental right to have health care provided to them by their government.

Cost of care

Socialized medicine amongst industrialized countries tends to be more affordable than in systems where there is little government involvement. A 2003 study examined costs and outputs in the U.S. and other industrialized countries and broadly concluded that the U.S. spends so much because its health care system is more costly. It noted that "the United States spent considerably more on health care than any other country ... [yet] most measures of aggregate utilization such as physician visits per capita and hospital days per capita were below the OECD median. Since spending is a product of both the goods and services used and their prices, this implies that much higher prices are paid in the United States than in other countries. The researchers examined possible reasons and concluded that input costs were high (salaries, cost of pharmaceutical), and that the complex payment system in the U.S. added higher administrative costs. Comparison countries in Canada and Europe were much more willing to exert monopsony power to drive down prices, whilst the highly fragmented buy side of the U.S. health system was one factor that could explain the relatively high prices in the United States of America. The current fee-for-service payment system also stimulates expensive care by promoting procedures over visits through financially rewarding the former ($1,500 – for doing a 10-minute procedure) vs. the latter ($50 – for a 30–45 minute visit). This causes the proliferation of specialists (more expensive care) and creating, what Don Berwick refers to as, "the world's best healthcare system for rescue care".

Other studies have found no consistent and systematic relationship between the type of financing of health care and cost containment; the efficiency of operation of the health care system itself appears to depend much more on how providers are paid and how the delivery of care is organized than on the method used to raise these funds.

Some supporters argue that government involvement in health care would reduce costs not just because of the exercise of monopsony power, e.g. in drug purchasing, but also because it eliminates profit margins and administrative overhead associated with private insurance, and because it can make use of economies of scale in administration. In certain circumstances, a volume purchaser may be able to guarantee sufficient volume to reduce overall prices while providing greater profitability to the seller, such as in so-called "purchase commitment" programs. Economist Arnold Kling attributes the present cost crisis mainly to the practice of what he calls premium medicine, which overuses expensive forms of technology that is of marginal or no proven benefit.

Milton Friedman has argued that government has weak incentives to reduce costs because "nobody spends somebody else’s money as wisely or as frugally as he spends his own". Others contend that health care consumption is not like other consumer consumption. Firstly there is a negative utility of consumption (consuming more health care does not make one better off) and secondly there is an information asymmetry between consumer and supplier.

Paul Krugman and Robin Wells argue that all of the evidence indicates that public insurance of the kind available in several European countries achieves equal or better results at much lower cost, a conclusion that also applies within the United States. In terms of actual administrative costs, Medicare spent less than 2% of its resources on administration, while private insurance companies spent more than 13%. The Cato Institute argues that the 2% Medicare cost figure ignores all costs shifted to doctors and hospitals, and alleges that Medicare is not very efficient at all when those costs are incorporated. Some studies have found that the U.S. wastes more on bureaucracy (compared to the Canadian level), and that this excess administrative cost would be sufficient to provide health care to the uninsured population in the U.S.

Notwithstanding the arguments about Medicare, there is overall less bureaucracy in socialized systems than in the present mixed U.S. system. Spending on administration in Finland is 2.1% of all health care costs, and in the UK the figure is 3.3% whereas the U.S. spends 7.3% of all expenditures on administration.

Quality of care

Some in the U.S. claim that socialized medicine would reduce health care quality. The quantitative evidence for this claim is not clear. The WHO has used Disability Adjusted Life Expectancy (the number of years an average person can expect to live in good health) as a measure of a nation's health achievement, and has ranked its member nations by this measure. The U.S. ranking was 24th, worse than similar industrial countries with high public funding of health such as Canada (ranked 5th), the UK (12th), Sweden (4th), France (3rd) and Japan (1st). But the U.S. ranking was better than some other European countries such as Ireland, Denmark and Portugal, which came 27th, 28th and 29th respectively. Finland, with its relatively high death rate from guns and renowned high suicide rate came above the U.S. in 20th place. The British have a Care Quality Commission that commissions independent surveys of the quality of care given in its health institutions and these are publicly accessible over the internet. These determine whether health organizations are meeting public standards for quality set by government and allows regional comparisons. Whether these results indicate a better or worse situation to that in other countries such as the U.S. is hard to tell because these countries tend to lack a similar set of standards.

Taxation

Opponents claim that socialized medicine would require higher taxes but international comparisons do not support this; the ratio of public to private spending on health is lower in the U.S. than that of Canada, Australia, New Zealand, Japan, or any EU country, yet the per capita tax funding of health in those countries is already lower than that of the United States.

Taxation is not necessarily an unpopular form of funding for health care. In England, a survey for the British Medical Association of the general public showed overwhelming support for the tax funding of health care. Nine out of ten people agreed or strongly agreed with a statement that the NHS should be funded from taxation with care being free at the point of use.

An opinion piece in The Wall Street Journal by two conservative Republicans argues that government sponsored health care will legitimatize support for government services generally, and make an activist government acceptable. "Once a large number of citizens get their health care from the state, it dramatically alters their attachment to government. Every time a tax cut is proposed, the guardians of the new medical-welfare state will argue that tax cuts would come at the expense of health care -- an argument that would resonate with middle-class families entirely dependent on the government for access to doctors and hospitals."

Innovation

Some in the U.S. argue that if government were to use its size to bargain down health care prices, this would undermine American leadership in medical innovation. It is argued that the high level of spending in the U.S. health care system and its tolerance of waste is actually beneficial because it underpins American leadership in medical innovation, which is crucial not just for Americans, but for the entire world.

Others point out that the American health care system spends more on state-of-the-art treatment for people who have good insurance, and spending is reduced on those lacking it and question the costs and benefits of some medical innovations, noting, for example, that "rising spending on new medical technologies designed to address heart disease has not meant that more patients have survived."

Access

One of the goals of socialized medicine systems is ensuring universal access to health care. Opponents of socialized medicine say that access for low-income individuals can be achieved by means other than socialized medicine, for example, income-related subsidies can function without public provision of either insurance or medical services. Economist Milton Friedman said the role of the government in health care should be restricted to financing hard cases. Universal coverage can also be achieved by making purchase of insurance compulsory. For example, European countries with socialized medicine in the broader sense, such as Germany and The Netherlands, operate in this way. A legal obligation to purchase health insurance is akin to a mandated health tax, and the use of public subsidies is a form of directed income redistribution via the tax system. Such systems give the consumer a free choice amongst competing insurers whilst achieving universality to a government directed minimum standard. 

Compulsory health insurance or savings are not limited to so-called socialized medicine, however. Singapore's health care system, which is often referred to as a free-market or mixed system, makes use of a combination of compulsory participation and state price controls to achieve the same goals.

Rationing (access, coverage, price, and time)

Part of the current debate about health care in the United States revolves around whether the Affordable Care Act as part of health care reform will result in a more systematic and logical allocation of health care. Opponents tend to believe that the law will eventually result in a government takeover of health care and ultimately to socialized medicine and rationing based not on being able to afford the care you want but on whether a third party other than the patient and the doctor decides whether the procedure or the cost is justifiable. Supporters of reform point out that health care rationing already exists in the United States through insurance companies issuing denial for reimbursement on the grounds that the insurance company believes the procedure is experimental or will not assist even though the doctor has recommended it. A public insurance plan was not included in the Affordable Care Act but some argue that it would have added to health care access choices, and others argue that the central issue is whether health care is rationed sensibly.

Opponents of reform invoke the term socialized medicine because they say it will lead to health care rationing by denial of coverage, denial of access, and use of waiting lists, but often do so without acknowledging coverage denial, lack of access and waiting lists exist in the U.S. health care system currently or that waiting lists in the U.S. are sometimes longer than the waiting lists in countries with socialized medicine. Proponents of the reform proposal point out a public insurer is not akin to a socialized medicine system because it will have to negotiate rates with the medical industry just as other insurers do and cover its cost with premiums charged to policyholders just as other insurers do without any form of subsidy. 

There is a frequent misunderstanding to think that waiting happens in places like the United Kingdom and Canada but does not happen in the United States. For instance it is not uncommon even for emergency cases in some U.S. hospitals to be boarded on beds in hallways for 48 hours or more due to lack of inpatient beds and people in the U.S. rationed out by being unable to afford their care are simply never counted and may never receive the care they need, a factor that is often overlooked. Statistics about waiting times in national systems are an honest approach to the issue of those waiting for access to care. Everyone waiting for care is reflected in the data, which, in the UK for example, are used to inform debate, decision-making and research within the government and the wider community. Some people in the U.S. are rationed out of care by unaffordable care or denial of access by HMOs and insurers or simply because they cannot afford co-pays or deductibles even if they have insurance. These people wait an indefinitely long period and may never get care they need, but actual numbers are simply unknown because they are not recorded in official statistics.

Opponents of the current reform care proposals fear that U.S. comparative effective research (a plan introduced in the stimulus bill) will be used to curtail spending and ration treatments, which is one function of the National Institute for Health and Care Excellence (NICE), arguing that rationing by market pricing rather by government is the best way for care to be rationed. However, when defining any group scheme, the same rules must apply to everyone in the scheme so some coverage rules had to be established. Britain has a national budget for public funded health care, and recognizes there has to be a logical trade off between spending on expensive treatments for some against, for example, caring for sick children. NICE is therefore applying the same market pricing principles to make the hard job of deciding between funding some treatments and not funding others on behalf of everyone in the insured pool. This rationing does not preclude choice of obtaining insurance coverage for excluded treatment as insured persons do having the choice to take out supplemental health insurance for drugs and treatments that the NHS does not cover (at least one private insurer offers such a plan) or from meeting treatment costs out-of-pocket. 

The debate in the U.S. over rationing has enraged some in the UK and statements made by politicians such as Sarah Palin and Chuck Grassley resulted in a mass Internet protest on websites such as Twitter and Facebook under the banner title "welovetheNHS" with positive stories of NHS experiences to counter the negative ones being expressed by these politicians and others and by certain media outlets such as Investor's Business Daily and Fox News. In the UK, it is private health insurers that ration care (in the sense of not covering the most common services such as access to a primary care physician or excluding pre-existing conditions) rather than the NHS. Free access to a general practitioner is a core right in the NHS, but private insurers in the UK will not pay for payments to a private primary care physician. Private insurers exclude many of the most common services as well as many of the most expensive treatments, whereas the vast majority of these are not excluded from the NHS but are obtainable at no cost to the patient. According to the Association of British Insurers (ABI), a typical policy will exclude the following: going to a general practitioner; going to accident and emergency; drug abuse; HIV/AIDS; normal pregnancy; gender reassignment; mobility aids, such as wheelchairs; organ transplant; injuries arising from dangerous hobbies (often called hazardous pursuits); pre-existing conditions; dental services; outpatient drugs and dressings; deliberately self-inflicted injuries; infertility; cosmetic treatment; experimental or unproven treatment or drugs; and war risks. Chronic illnesses, such as diabetes and end stage renal disease requiring dialysis are also excluded from coverage. Insurers do not cover these because they feel they do not need to since the NHS already provides coverage and to provide the choice of a private provider would make the insurance prohibitively expensive. Thus in the UK there is cost shifting from the private sector to the public sector, which again is the opposite of the allegation of cost shifting in the U.S. from public providers such as Medicare and Medicaid to the private sector.

Palin had alleged that America will create rationing "death panels" to decide whether old people could live or die, again widely taken to be a reference to NICE. U.S. Senator Chuck Grassley alleged that he was told that Senator Edward Kennedy would have been refused the brain tumor treatment he was receiving in the United States had he instead lived a country with government run health care. This, he alleged, would have been due to rationing because of Kennedy's age (77 years) and the high cost of treatment. The UK Department of Health said that Grassley’s claims were "just wrong" and reiterated health service in Britain provides health care on the basis of clinical need regardless of age or ability to pay. The chairman of the British Medical Association, Hamish Meldrum, said he was dismayed by the "jaw-droppingly untruthful attacks" made by American critics. The chief executive of the National Institute for Health and Clinical Excellence (NICE), told The Guardian newspaper that "it is neither true, nor is it anything you could extrapolate from anything we've ever recommended" that Kennedy would be denied treatment by the NHS. The business journal Investor's Business Daily claimed mathematician and astrophysicist Stephen Hawking, who had ALS and spoke with the aid of an American-accented voice synthesizer, would not have survived if he had been treated in the British National Health Service. Hawking was British and was treated throughout his life (67 years) by the NHS and issued a statement to the effect he owed his life to the quality of care he has received from the NHS.

Some argue that countries with national health care may use waiting lists as a form of rationing compared to countries that ration by price, such as the United States, according to several commentators and healthcare experts. The Washington Post columnist Ezra Klein compared 27% of Canadians reportedly waiting four months or more for elective surgery with 26% of Americans reporting that they did not fulfill a prescription due to cost (compared to only 6% of Canadians). Britain's former age-based policy that once prevented the use of kidney dialysis as treatment for older patients with renal problems, even to those who can privately afford the costs, has been cited as another example. A 1999 study in the Journal of Public Economics analyzed the British National Health Service and found that its waiting times function as an effective market disincentive, with a low elasticity of demand with respect to time.

Supporters of private price rationing over waiting time rationing, such as The Atlantic columnist Megan McArdle, argue time rationing leaves patients worse off since their time (measured as an opportunity cost) is worth much more than the price they would pay. Opponents also state categorizing patients based on factors such as social value to the community or age will not work in a heterogeneous society without a common ethical consensus such as the U.S. Doug Bandow of the CATO Institute wrote that government decision making would "override the differences in preferences and circumstances" for individuals and that it is a matter of personal liberty to be able to buy as much or as little care as one wants. Neither argument recognizes the fact that in most countries with socialized medicine, a parallel system of private health care allows people to pay extra to reduce their waiting time. The exception is that some provinces in Canada disallow the right to bypass queuing unless the matter is one in which the rights of the person under the constitution.

A 1999 article in the British Medical Journal, stated "there is much merit in using waiting lists as a rationing mechanism for elective health care if the waiting lists are managed efficiently and fairly." Dr. Arthur Kellermann, associate dean for health policy at Emory University, stated rationing by ability to pay rather than by anticipated medical benefits in the U.S. makes its system more unproductive, with poor people avoiding preventive care and eventually using expensive emergency treatment. Ethicist Daniel Callahan has written that U.S. culture overly emphasizes individual autonomy rather than communitarian morals and that stops beneficial rationing by social value, which benefits everyone.

Some argue that waiting lists result in great pain and suffering, but again evidence for this is unclear. In a recent survey of patients admitted to hospital in the UK from a waiting list or by planned appointment, only 10% reported they felt they should have been admitted sooner than they were. 72% reported the admission was as timely as they felt necessary. Medical facilities in the U.S. do not report waiting times in national statistics as is done in other countries and it is a myth to believe there is no waiting for care in the U.S. Some argue that wait times in the U.S. could actually be as long as or longer than in other countries with universal health care.

There is considerable argument about whether any of the health bills currently before congress will introduce rationing. Howard Dean for example contested in an interview that they do not. However, Politico has pointed out that all health systems contain elements of rationing (such as coverage rules) and the public health care plan will therefore implicitly involve some element of rationing.

Political interference and targeting

In the UK, where government employees or government-employed sub-contractors deliver most health care, political interference is quite hard to discern. Most supply-side decisions are in practice under the control of medical practitioners and of boards comprising the medical profession. There is some antipathy towards the target-setting by politicians in the UK. Even the NICE criteria for public funding of medical treatments were never set by politicians. Nevertheless, politicians have set targets, for instance to reduce waiting times and to improve choice. Academics have pointed out that the claims of success of the targeting are statistically flawed.

The veracity and significance of the claims of targeting interfering with clinical priorities are often hard to judge. For example, some UK ambulance crews have complained that hospitals would deliberately leave patients with ambulance crews to prevent an accident and emergency department (A&E, or emergency room) target-time for treatment from starting to run. The Department of Health vehemently denied the claim, because the A&E time begins when the ambulance arrives at the hospital and not after the handover. It defended the A&E target by pointing out that the percentage of people waiting four hours or more in A&E had dropped from just under 25% in 2004 to less than 2% in 2008. The original Observer article reported that in London, 14,700 ambulance turnarounds were longer than an hour and 332 were more than two hours when the target turnaround time is 15 minutes. However, in the context of the total number of emergency ambulance attendances by the London Ambulance Service each year (approximately 865,000), these represent just 1.6% and 0.03% of all ambulance calls. The proportion of these attributable to patients left with ambulance crews is not recorded. At least one junior doctor has complained that the four-hour A&E target is too high and leads to unwarranted actions that are not in the best interests of patients.

Political targeting of waiting-times in Britain has had dramatic effects. The National Health Service reports that the median admission wait-time for elective inpatient treatment (non-urgent hospital treatment) in England at the end of August 2007, was just under 6 weeks, and 87.5% of patients were admitted within 13 weeks. Reported waiting times in England also overstate the true waiting-time. This is because the clock starts ticking when the patient has been referred to a specialist by the GP and it only stops when the medical procedure is completed. The 18-week maximum waiting period target thus includes all the time taken for the patient to attend the first appointment with the specialist, time for any tests called for by the specialist to determine precisely the root of the patient's problem and the best way to treat it. It excludes time for any intervening steps deemed necessary prior to treatment, such as recovery from some other illness or the losing of excessive weight.

Health system

From Wikipedia, the free encyclopedia

A health system, also sometimes referred to as health care system or as healthcare system, is the organization of people, institutions, and resources that deliver health care services to meet the health needs of target populations.
 
There is a wide variety of health systems around the world, with as many histories and organizational structures as there are nations. Implicitly, nations must design and develop health systems in accordance with their needs and resources, although common elements in virtually all health systems are primary healthcare and public health measures. In some countries, health system planning is distributed among market participants. In others, there is a concerted effort among governments, trade unions, charities, religious organizations, or other co-ordinated bodies to deliver planned health care services targeted to the populations they serve. However, health care planning has been described as often evolutionary rather than revolutionary.

Goals

The World Health Organization (WHO), the directing and coordinating authority for health within the United Nations system, is promoting a goal of universal health care: to ensure that all people obtain the health services they need without suffering financial hardship when paying for them. According to WHO, healthcare systems' goals are good health for the citizens, responsiveness to the expectations of the population, and fair means of funding operations. Progress towards them depends on how systems carry out four vital functions: provision of health care services, resource generation, financing, and stewardship. Other dimensions for the evaluation of health systems include quality, efficiency, acceptability, and equity. They have also been described in the United States as "the five C's": Cost, Coverage, Consistency, Complexity, and Chronic Illness. Also, continuity of health care is a major goal.

Definitions

Often health system has been defined with a reductionist perspective, for example reducing it to healthcare system. In many publications, for example, both expressions are used interchangeably. Some authors have developed arguments to expand the concept of health systems, indicating additional dimensions that should be considered:
  • Health systems should not be expressed in terms of their components only, but also of their interrelationships;
  • Health systems should include not only the institutional or supply side of the health system, but also the population;
  • Health systems must be seen in terms of their goals, which include not only health improvement, but also equity, responsiveness to legitimate expectations, respect of dignity, and fair financing, among others;
  • Health systems must also be defined in terms of their functions, including the direct provision of services, whether they are medical or public health services, but also "other enabling functions, such as stewardship, financing, and resource generation, including what is probably the most complex of all challenges, the health workforce."

World Health Organization definition

The World Health Organization defines health systems as follows:
A health system consists of all organizations, people and actions whose primary intent is to promote, restore or maintain health. This includes efforts to influence determinants of health as well as more direct health-improving activities. A health system is therefore more than the pyramid of publicly owned facilities that deliver personal health services. It includes, for example, a mother caring for a sick child at home; private providers; behaviour change programmes; vector-control campaigns; health insurance organizations; occupational health and safety legislation. It includes inter-sectoral action by health staff, for example, encouraging the ministry of education to promote female education, a well known determinant of better health.

Providers

Healthcare providers are institutions or individuals providing healthcare services. Individuals including health professionals and allied health professions can be self-employed or working as an employee in a hospital, clinic, or other health care institution, whether government operated, private for-profit, or private not-for-profit (e.g. non-governmental organization). They may also work outside of direct patient care such as in a government health department or other agency, medical laboratory, or health training institution. Examples of health workers are doctors, nurses, midwives, dietitians, paramedics, dentists, medical laboratory technologists, therapists, psychologists, pharmacists, chiropractors, optometrists, community health workers, traditional medicine practitioners, and others.

Financial resources

There are generally five primary methods of funding health systems:
  1. general taxation to the state, county or municipality
  2. national health insurance
  3. voluntary or private health insurance
  4. out-of-pocket payments
  5. donations to charities
Most countries' systems feature a mix of all five models. One study based on data from the OECD concluded that all types of health care finance "are compatible with" an efficient health system. The study also found no relationship between financing and cost control.

The term health insurance is generally used to describe a form of insurance that pays for medical expenses. It is sometimes used more broadly to include insurance covering disability or long-term nursing or custodial care needs. It may be provided through a social insurance program, or from private insurance companies. It may be obtained on a group basis (e.g., by a firm to cover its employees) or purchased by individual consumers. In each case premiums or taxes protect the insured from high or unexpected health care expenses.

By estimating the overall cost of health care expenses, a routine finance structure (such as a monthly premium or annual tax) can be developed, ensuring that money is available to pay for the health care benefits specified in the insurance agreement. The benefit is typically administered by a government agency, a non-profit health fund or a corporation operating seeking to make a profit.

Many forms of commercial health insurance control their costs by restricting the benefits that are paid by through deductibles, co-payments, coinsurance, policy exclusions, and total coverage limits and will severely restrict or refuse coverage of pre-existing conditions. Many government schemes also have co-payment schemes but exclusions are rare because of political pressure. The larger insurance schemes may also negotiate fees with providers. 

Many forms of social insurance schemes control their costs by using the bargaining power of their community they represent to control costs in the health care delivery system. For example, by negotiating drug prices directly with pharmaceutical companies negotiating standard fees with the medical profession, or reducing unnecessary health care costs. Social schemes sometimes feature contributions related to earnings as part of a scheme to deliver universal health care, which may or may not also involve the use of commercial and non-commercial insurers. Essentially the more wealthy pay proportionately more into the scheme to cover the needs of the relatively poor who therefore contribute proportionately less. There are usually caps on the contributions of the wealthy and minimum payments that must be made by the insured (often in the form of a minimum contribution, similar to a deductible in commercial insurance models). 

In addition to these traditional health care financing methods, some lower income countries and development partners are also implementing non-traditional or innovative financing mechanisms for scaling up delivery and sustainability of health care, such as micro-contributions, public-private partnerships, and market-based financial transaction taxes. For example, as of June 2011, UNITAID had collected more than one billion dollars from 29 member countries, including several from Africa, through an air ticket solidarity levy to expand access to care and treatment for HIV/AIDS, tuberculosis and malaria in 94 countries.

Payment models

In most countries, wage costs for healthcare practitioners are estimated to represent between 65% and 80% of renewable health system expenditures. There are three ways to pay medical practitioners: fee for service, capitation, and salary. There has been growing interest in blending elements of these systems.

Fee-for-service

Fee-for-service arrangements pay general practitioners (GPs) based on the service. They are even more widely used for specialists working in ambulatory care.

There are two ways to set fee levels:
  • By individual practitioners.
  • Central negotiations (as in Japan, Germany, Canada and in France) or hybrid model (such as in Australia, France's sector 2, and New Zealand) where GPs can charge extra fees on top of standardized patient reimbursement rates.

Capitation

In capitation payment systems, GPs are paid for each patient on their "list", usually with adjustments for factors such as age and gender. According to OECD, "these systems are used in Italy (with some fees), in all four countries of the United Kingdom (with some fees and allowances for specific services), Austria (with fees for specific services), Denmark (one third of income with remainder fee for service), Ireland (since 1989), the Netherlands (fee-for-service for privately insured patients and public employees) and Sweden (from 1994). Capitation payments have become more frequent in "managed care" environments in the United States."

According to OECD, "Capitation systems allow funders to control the overall level of primary health expenditures, and the allocation of funding among GPs is determined by patient registrations. However, under this approach, GPs may register too many patients and under-serve them, select the better risks and refer on patients who could have been treated by the GP directly. Freedom of consumer choice over doctors, coupled with the principle of "money following the patient" may moderate some of these risks. Aside from selection, these problems are likely to be less marked than under salary-type arrangements."

Salary arrangements

In several OECD countries, general practitioners (GPs) are employed on salaries for the government. According to OECD, "Salary arrangements allow funders to control primary care costs directly; however, they may lead to under-provision of services (to ease workloads), excessive referrals to secondary providers and lack of attention to the preferences of patients." There has been movement away from this system.

Value-Based Care

In recent years, providers have been switching from fee-for-service payment models to a value-based care payment system, where they are compensated for providing value to patients. In this system, providers are given incentives to close gaps in care and provide better quality care for patients. 

Information resources

Sound information plays an increasingly critical role in the delivery of modern health care and efficiency of health systems. Health informatics – the intersection of information science, medicine and healthcare – deals with the resources, devices, and methods required to optimize the acquisition and use of information in health and biomedicine. Necessary tools for proper health information coding and management include clinical guidelines, formal medical terminologies, and computers and other information and communication technologies. The kinds of health data processed may include patients' medical records, hospital administration and clinical functions, and human resources information

The use of health information lies at the root of evidence-based policy and evidence-based management in health care. Increasingly, information and communication technologies are being utilised to improve health systems in developing countries through: the standardisation of health information; computer-aided diagnosis and treatment monitoring; informing population groups on health and treatment.

Management

The management of any health system is typically directed through a set of policies and plans adopted by government, private sector business and other groups in areas such as personal healthcare delivery and financing, pharmaceuticals, health human resources, and public health.

Public health is concerned with threats to the overall health of a community based on population health analysis. The population in question can be as small as a handful of people, or as large as all the inhabitants of several continents (for instance, in the case of a pandemic). Public health is typically divided into epidemiology, biostatistics and health services. Environmental, social, behavioral, and occupational health are also important subfields.

Today, most governments recognize the importance of public health programs in reducing the incidence of disease, disability, the effects of ageing and health inequities, although public health generally receives significantly less government funding compared with medicine. For example, most countries have a vaccination policy, supporting public health programs in providing vaccinations to promote health. Vaccinations are voluntary in some countries and mandatory in some countries. Some governments pay all or part of the costs for vaccines in a national vaccination schedule. 

The rapid emergence of many chronic diseases, which require costly long-term care and treatment, is making many health managers and policy makers re-examine their healthcare delivery practices. An important health issue facing the world currently is HIV/AIDS. Another major public health concern is diabetes. In 2006, according to the World Health Organization, at least 171 million people worldwide suffered from diabetes. Its incidence is increasing rapidly, and it is estimated that by the year 2030, this number will double. A controversial aspect of public health is the control of tobacco smoking, linked to cancer and other chronic illnesses.

Antibiotic resistance is another major concern, leading to the reemergence of diseases such as tuberculosis. The World Health Organization, for its World Health Day 2011 campaign, is calling for intensified global commitment to safeguard antibiotics and other antimicrobial medicines for future generations.

Health systems performance

Since 2000, more and more initiatives have been taken at the international and national levels in order to strengthen national health systems as the core components of the global health system. Having this scope in mind, it is essential to have a clear, and unrestricted, vision of national health systems that might generate further progresses in global health. The elaboration and the selection of performance indicators are indeed both highly dependent on the conceptual framework adopted for the evaluation of the health systems performances. Like most social systems, health systems are complex adaptive systems where change does not necessarily follow rigid management models. In complex systems path dependency, emergent properties and other non-linear patterns are seen, which can lead to the development of inappropriate guidelines for developing responsive health systems.

An increasing number of tools and guidelines are being published by international agencies and development partners to assist health system decision-makers to monitor and assess health systems strengthening including human resources development using standard definitions, indicators and measures. In response to a series of papers published in 2012 by members of the World Health Organization's Task Force on Developing Health Systems Guidance, researchers from the Future Health Systems consortium argue that there is insufficient focus on the 'policy implementation gap'. Recognizing the diversity of stakeholders and complexity of health systems is crucial to ensure that evidence-based guidelines are tested with requisite humility and without a rigid adherence to models dominated by a limited number of disciplines. Healthcare services often implement Quality Improvement Initiatives to overcome this policy implementation gap. Although many deliver improved healthcare a large proportion fail to sustain. Numerous tools and frameworks have been created to respond to this challenge and increase improvement longevity. One tool highlighted the need for these tools to respond to user preferences and settings to optimize impact.

Health Policy and Systems Research (HPSR) is an emerging multidisciplinary field that challenges 'disciplinary capture' by dominant health research traditions, arguing that these traditions generate premature and inappropriately narrow definitions that impede rather than enhance health systems strengthening. HPSR focuses on low- and middle-income countries and draws on the relativist social science paradigm which recognises that all phenomena are constructed through human behaviour and interpretation. In using this approach, HPSR offers insight into health systems by generating a complex understanding of context in order to enhance health policy learning. HPSR calls for greater involvement of local actors, including policy makers, civil society and researchers, in decisions that are made around funding health policy research and health systems strengthening.

International comparisons

Health systems can vary substantially from country to country, and in the last few years, comparisons have been made on an international basis. The World Health Organization, in its World Health Report 2000, provided a ranking of health systems around the world according to criteria of the overall level and distribution of health in the populations, and the responsiveness and fair financing of health care services. The goals for health systems, according to the WHO's World Health Report 2000 – Health systems: improving performance (WHO, 2000), are good health, responsiveness to the expectations of the population, and fair financial contribution. There have been several debates around the results of this WHO exercise, and especially based on the country ranking linked to it, insofar as it appeared to depend mostly on the choice of the retained indicators

Direct comparisons of health statistics across nations are complex. The Commonwealth Fund, in its annual survey, "Mirror, Mirror on the Wall", compares the performance of the health systems in Australia, New Zealand, the United Kingdom, Germany, Canada and the United States Its 2007 study found that, although the United States system is the most expensive, it consistently underperforms compared to the other countries. A major difference between the United States and the other countries in the study is that the United States is the only country without universal health care. The OECD also collects comparative statistics, and has published brief country profiles. Health Consumer Powerhouse makes comparisons between both national health care systems in the Euro health consumer index and specific areas of health care such as diabetes  or hepatitis.
