Due to the near-universal desire for safe and good quality healthcare, there is a growing interest in international healthcare accreditation. Providing healthcare, especially of an adequate standard, is a complex and challenging process. Healthcare is a vital and emotive issue--its importance pervades all aspects of societies, and it has medical, social, political, ethical, business, and financial ramifications. In any part of the world healthcare services can be provided either by the public sector or by the private sector, or by a combination of both, and the site of delivery of healthcare can be located in hospitals or be accessed through practitioners working in the community, such as general medical practitioners and dentists.
This is occurring in most parts of the developed world in a setting in which people are expressing ever-greater expectations of hospitals and healthcare services. This trend is especially strong where socialised medical systems exist. For example, in the European Union "... patients have ever-greater expectations of what health systems ought to deliver," although there has been a "... continuous rise in costs of services determined by scientific and technological innovation." And in one particular EU member state, the United Kingdom, "... People are going to increase demand and they have also got an increased expectation of what the NHS can deliver." The USA manifests some differences here, and is an unusual and distinct oddity among developed Western countries. In 2007, 45.7 million of the overall US population (i.e. 15.3%) had no health insurance whatsoever yet in 2007 the USA spent nearly $2.3 trillion on healthcare, or 16% of the country's gross domestic product, more than twice as much per capita as the OECD average. Because of this, some US citizens are having to look outside of their country to find affordable healthcare, through the medium of medical tourism, also known as "Global Healthcare" (see below).
Apart from using hospitals and healthcare services to regain their health if it has become impaired, or to prevent ill health occurring in the first place, people the world over may also use them for a wide variety of other services, for example "improving upon nature" (e.g. cosmetic surgery, gender reassignment surgery or acquiring help to overcome difficulties with becoming a parent (e.g. infertility treatment).
Fundamentally healthcare and hospital accreditation is about improving how care is delivered to patients and the quality of the care they receive. Accreditation has been defined as "A self-assessment and external peer assessment process used by health care organisations to accurately assess their level of performance in relation to established standards and to implement ways to continuously improve"  Interest in hospital accreditation ascends as far as the World Health Organization (see external links). Accreditation is one important component in patient safety. However, there is limited and contested evidence supporting the effectiveness of accreditation programs.
In the USA in the early 20th century, there was concern over how to best create an appropriate environment in which clinicians could work. Standards to improve the control of the hospital environment were thus generated, and these subsequently grew into accreditation schemes with the remit to facilitate and improve organisational development. Part of the process is not only about assessing quality, but also about promoting and improving quality. Similar accreditation schemes were soon developed elsewhere in the world.
In countries such as the United Kingdom, the United States, Australia, New Zealand and Canada, sophisticated accreditation groups have grown up to survey hospitals (and, in some cases, healthcare in the community). Furthermore, other accreditation groups have been set up with openly declared remits to look after just one particular area of healthcare, such as laboratory medicine or psychiatric services or sexual health.
Accreditation systems are structured so as to provide objective measures for the external evaluation of quality and quality management. Accreditation schemes should ideally focus primarily on the patient and their pathway through the healthcare system - this includes how they access care, how they are cared for after discharge from hospital, and the quality of the services provided for them. At the heart of these schemes is a list of standards which, ideally, serve to assess evaluate in a systematic and comprehensive way the standards of professional performance in a hospital. This includes not only hand-on patient care but also training and education of staff, credentials, clinical governance and audit, research activity, ethical standards etc. The standards can also be used internally by hospitals to develop and improve their quality standards and quality management. Some international accreditation schemes believe that the standards applied should be fixed and are non-negotiable, while others operate a system of negotiation over standards - however, whatever approach is taken the every aspect of the process should be evidence-based.
International standardization groups also exist, but it must be pointed out that the mere achieving of set standards is not the only factor involved in quality accreditation - there is also the significant matter of the incorporating into participating hospitals systems of self-examination, problem solving and self-improvement, and hence there is more to accreditation than following some sort of overall "standardization" process.
As governments and the general public have increasingly come to demand more and more openness about health care and its delivery, including and especially hospital quality and safety and the clinical performance of doctors, and these accreditation systems have generally adapted to fulfill this extended role.
However, accreditation should ideally be independent of governmental control, and accreditation groups should assess hospitals "holistically", and not just some isolated facet of the hospital's activities or services such as the laboratories, pharmacy services, infection control, financial health or information technology services (indeed, partial accreditation of this type should be publicly acknowledged as such by both the accreditation scheme and the hospital). The best accreditation schemes also assess academic and intellectual activity (such as teaching and research) within those hospitals that they survey (see later) and have a clear and declared interest in medical ethics.
In some parts of the world, accessing healthcare can be very expensive, even prohibitively so. While some countries have elected to provide comprehensive healthcare services for all of their populations, others appear to be satisfied with leaving portions of their population without access to healthcare. When it comes to who pays the bills for healthcare, it may be the government or it may be the individual (sometimes either by direct payment, and sometimes through employer-run schemes, insurance companies etc.), or a combination of both. However, healthcare can never be truly "free" - someone somewhere will always have to pay, and the payer will always want the best value for money possible. "Affordability" of healthcare can be the insurmountable hurdle for some human beings. Value for money is hence another factor in assessing the true quality of healthcare.
A number of larger countries engage in hospital accreditation that is provided internally. Taking the USA as an example, numerous groups provide accreditation for internal healthcare organizations, including the AAAHC Accreditation Association for Ambulatory Health Care, doing business internationally as "Acreditas Global", Community Health Accreditation Program (CHAP), the Joint Commission, TJC, Accreditation Commission for Health Care, Inc. (ACHC), the "Exemplary Provider Program" of The Compliance Team, American Accreditation Commission International (AACI), and the Healthcare Quality Association on Accreditation (HQAA).
Some other countries have looked towards accessing the services of the major international healthcare accreditation groups based in other countries to assess their healthcare services. There are many reasons for this, including cost, a desire to improve healthcare quality for one's own citizens (good governance is at the basis of all high-quality healthcare), or a desire to market one's healthcare services to "medical tourists" (see below). Some hospitals go for international healthcare accreditation as a de facto form of advertising.
In response to this marketing opportunity, some national accreditation groups have expanded their wings internationally, and gone on to survey and accredit hospitals outside of their own national borders. When they choose to do this, such groups can be said to be providing "international healthcare accreditation".
This process of accreditation has been made increasingly complicated by the fact that in many parts of the world, more and more human beings are choosing to cross international borders to access healthcare, a phenomenon known as "medical tourism" or "Global Healthcare". Medical tourism/Global Healthcare cannot be ignored as a key issue in international healthcare accreditation - it is becoming increasingly important as millions of (especially) Europeans and Americans seek healthcare overseas outside of their own countries for a variety of reasons (including and especially affordability), and it represents a growing multibillion-euro/dollar/pound business of increasing importance to the economies of many countries, such as Singapore, Thailand, India, Hong Kong, Malaysia and the Philippines. The importance of medical tourism/Global Healthcare to the economy of developing countries is increasingly the subject of academic study. , and this synergy has a clear "knock-on" effect for those organizations based within the developed world who are seeking to develop the medical tourism/Global Healthcare market.
The following quotation, taken from the website of Partners Harvard Medical International, crystallizes the increasing relevance of international health care accreditation and its growing commercial importance, particularly in relation to medical tourism/global healthcare. "In competitive health care markets where patients have an increasing array of choices, quality is the most important differentiator for organizations striving for sustainability and both national and regional leadership. International accreditation has become a powerful indicator of a health care organization's commitment to high-quality care and patient safety." Reflecting this, much of the discussion on medical tourism blog sites reflects the increasing importance of international healthcare and hospital accreditation to this industry 
How does an individual contemplating becoming a medical tourist ensure that the overseas healthcare they are planning to access is as safe as possible and is of adequate quality? For sure, it is not simply a matter of looking at hospital buildings and at mattresses, and it is certainly not just an issue of looking only at the prices charged. While architecturally pleasing rooms and easier access to satellite television and the internet may improve personal comfort, and a bargain basement price may help the wallet, what is often more important may include such issues as:
The above list is not exhaustive, but it represents a good start. Also, the intending medical tourist should check whether or not a hospital is wholly accredited by an international accreditation group, or if it is only partly accredited (e.g. for infection control), the latter being less inclined to create confidence in a potential consumer.
How does the person in the street access this type of quality information? This can be very difficult. Accreditation schemes well-recognised as providing services in the international healthcare accreditation field include:
The different accreditation schemes vary in approach, quality, size, intent, sourcing of surveyors and the skill of their marketing. They also vary in terms of how much they charge hospitals and healthcare institutions for their services. They all have web sites.
The International Society for Quality in Health Care (ISQua) is an umbrella organisation for such organisations providing international healthcare accreditation . Its offices are based in the Republic of Ireland. ISQua is a small non-profit limited company with members in over 70 countries. ISQua works to provide services to guide health professionals, providers, researchers, agencies, policy makers and consumers, to achieve excellence in healthcare delivery to all people, and to continuously improve the quality and safety of care. ISQua does not actually survey or accredit hospitals or clinics itself.
The United Kingdom Accreditation Forum, or UKAF, is a UK-based umbrella organisation for organisations providing healthcare accreditation . Its offices are based in London. Like ISQua, UKAF does not actually survey and accredit hospitals itself. India becomes 12th nation to join ISQua.
If a hospital or clinic simply wishes to improve its services to patients wherever those patients come from (locally or from further afield), or wishes to attract medical tourists, how do they choose who to go to when contemplating accessing external peer review by an accreditation group such as those listed above. No one healthcare system has a monopoly of excellence and no one provider country or scheme can claim to be the total arbiter of quality. The same is true of healthcare accreditation schemes.
For example, some countries, such as the USA, perform very poorly when it comes to providing anything close to universal access to healthcare of adequate quality to the population living within their own borders. Others, such as the United Kingdom and Australia, have created state-funded systems which provide everything without the assistance of the private sector.
Different accreditation schemes are sourced out of different parts of the world, for example in hospitals there is (see map):
As no single international accreditation scheme enjoys exclusive rights to be seen as an overall worldwide-relevant scheme, some hospitals are looking towards multiple accreditation to achieve performance credibility in different parts of the world.
Other fields of accreditation exist, such as stronger use of general medical practices (sometimes known as GP or Family Medicine) is some westernised countries. GP accreditation services, such as the Royal College of General Practitioners (RGCP) in the United Kingdom, and Australian General Practice Accreditation Limited (AGPAL) in Australia provide accreditation services for these practices. With respect to the cost of accreditation, this can vary enormously  and it can be hard to find out precise data; in the case of JCI, the costs can be substantial. This is based on the country, size and operations of an organisation.
