Many scholars and global health practitioners express their opinions about what the right to health or UHC entails. Although these opinions are valuable, they do not carry authoritative weight. If we want to compare the normative content of the right to health with the normative content of UHC, we have to agree first on the authoritative sources.
With regards to the right to health, the authoritative sources are fairly easily identifiable. The human rights mentioned in the Universal Declaration of Human Rights (UDHR) was further elaborated in two primary covenants that together with the UDHR make up the International Bill of Rights: the International Covenant on Civil and Political Rights , and the International Covenant on Economic, Social and Cultural Rights . The right to health is included in the International Covenant on Economic, Social and Cultural Rights (International Covenant) . To monitor compliance with the International Covenant, a Committee on Economic, Social and Cultural Rights (Committee) was created, which issues authoritative interpretations of rights included in the International Covenant, the so-called ‘general comments’. General Comment 14 clarifies the scope and the content of the right to health .
With regards to UHC, authoritative sources are less easy to identify. There are no treaties about UHC. The 2005 World Health Assembly resolution on “Sustainable health financing, universal coverage and social health insurance” (2005 WHA Resolution) , has been accepted by the World Health Assembly, where almost all countries are represented and each country has one vote. We can therefore consider it as similar to a declaration by the United Nations. The same can be argued about the United Nations General Assembly resolution on “Global health and foreign policy”, adopted in December 2012 (2012 UNGA Resolution) . But both resolutions are relatively short and may not fully reflect the concept of UHC that the WHO has in mind when proposing it as the ‘single overarching’ new health goal. As there is no real equivalent of a general comment for UHC, we decided to include the 2010 World Health Report on UHC (2010 World Health Report) , and the WHO discussion paper on health in the post-2015 agenda (2012 WHO Discussion Paper)  in our analysis as well, assuming that they are both approved by the leadership of the WHO.
We faced an additional problem because the right to health is, according to General Comment 14, “an inclusive right extending not only to timely and appropriate health care but also to the underlying determinants of health, such as access to safe and potable water and adequate sanitation, an adequate supply of safe food, nutrition and housing, healthy occupational and environmental conditions, and access to health-related education and information, including on sexual and reproductive health” , whereas UHC is focused on health care – including “prevention, promotion, treatment and rehabilitation”, as the 2012 WHO Discussion Paper clarifies , but focused on health care nonetheless. We therefore decided to limit the scope of our comparative normative analysis to the right to health care, although we acknowledge that the absence of broader health determinants within UHC does limit its ability to practically express the right to health in totality.
To be sure, our ambition was not to provide a complete account of the comparative advantages of two different norms – or two different sets of norms; we merely tried to find and expose the main differences.
Comparing the right to health care with universal health coverage
The right to health care
The most authoritative formulation of the right to health is in article 12 of the International Covenant, which recognises “the right of everyone to the enjoyment of the highest attainable standard of physical and mental health” and prescribes specific steps for states to take in order to fully realise this right, including reducing the stillbirth rate and infant mortality; improving all aspects of environmental and industrial hygiene; preventing, treating, and controlling epidemic, endemic, occupational, and other diseases; and creating conditions that assure medical services and attention to all in the event of sickness .
The right to health has to be understood together with article 2(1) of the International Covenant, according to which states commit to “take steps, individually and through international assistance and co-operation, especially economic and technical, to the maximum of its available resources, with a view to achieving progressively the full realization of the rights recognized in the present Covenant by all appropriate means…” (emphasis added) . Thus the right to health does not provide an immediate entitlement to the best available health care in the world. The corresponding obligation upon states is “to take steps towards” providing the best available health care, taking into account that states’ resources are limited and that there are many rights to be realised – even the wealthiest states do not have unlimited resources for health care. Due to the greater availability of resources, the level of health care that a government of a wealthy state is obliged to ensure its residents is broader than that which a government of a poorer state is obliged to ensure its residents, such that the entitlement to health care will look different across different countries.
The Committee, established in 1985 to carry out the monitoring functions foreseen in the International Covenant, not only issues comments on states’ progress reports; it also issues ‘general comments’ on specific issues, and in 2000 it issued General Comment 14 on “the right to the highest attainable standard of health” . In General Comment 14, several important human rights principles are explained and applied to the right to health, including the following, which we identify for the purpose of comparison with UHC.
First, the principle of progressive realisation demands of each state to use the maximum of its available resources, as they evolve over time. When unable to provide health care available in other parts of the world, states are obliged to demonstrate their inability ; paragraphs 9 & 47.
Second, the principle of non-discrimination demands that the health care ensured by a given state to some people under its jurisdiction must be ensured to all people under its jurisdiction ; paragraphs 12, 18 & 19.
Third, if states are not obliged to provide the best health care available in the world, and if they are not allowed do discriminate against any particular group, then how are they supposed to make choices between the health care they will provide and the health care they will not provide? The principle of non-discrimination implies the public health principle of cost-effectiveness. “Expensive curative health services which are often accessible only to a small, privileged fraction of the population, rather than primary and preventive health care benefiting a far larger part of the population”, have been qualified as “[i]nappropriate health resource allocation [that] can lead to discrimination that may not be overt” ; paragraph 19.
Fourth, if the principle of non-discrimination implies a principle of cost-effectiveness, it also incorporates a principle of participatory decision-making. National public health strategies and plans of action that states are required to adopt and implement “shall be devised, and periodically reviewed, on the basis of a participatory and transparent process” ; paragraph 43f. Thus, determining the health care priorities is not purely a matter of epidemiology, but also of people’s expressed priorities.
Fifth, “the process by which the strategy and plan of action are devised, as well as their content, shall give particular attention to all vulnerable or marginalized groups” ; paragraph 43f. Because of the principle of prioritising vulnerable or marginalised groups, even if a particular health concern affects only a small portion of the population – and might fall from consideration if a pure cost-effectiveness analysis guides decision-making – if it disproportionately affects vulnerable or marginalised populations, it may well be incumbent for the state to include it as part of the health care that it ensures for everyone.
Sixth, all human rights have a minimum core, and all states, no matter how rich or poor, therefore have minimum core obligations. With regards to the entitlement to health care, states have “at least the following obligations: (a) To ensure the right of access to health facilities, goods and services on a non-discriminatory basis, especially for vulnerable or marginalized groups; (b) …; (c) …; (d) To provide essential drugs, as from time to time defined under the WHO Action Programme on Essential Drugs; (e) To ensure equitable distribution of all health facilities, goods and services;…” ; paragraph 43.
Seventh, the right to health includes the principle of shared responsibility. Article 2(1) of the International Covenant on Economic, Social and Cultural Rights prescribes that states “take steps, individually and through international assistance and co-operation, especially economic and technical, to the maximum of its available resources, …” (emphasis added) , and when the Committee elaborated states’ core obligations arising from the right to health, it explicitly referred to international assistance: “For the avoidance of any doubt, the Committee wishes to emphasize that it is particularly incumbent on States parties and other actors in a position to assist, to provide ‘international assistance and cooperation, especially economic and technical’ which enable developing countries to fulfil their core and other obligations…” ; paragraph 45. Thus, states must prioritise these core aspects of health care in providing international assistance.
In short, under the right to health and the entitlement to health care in particular, people can expect access to health facilities that provide the essential medicines they may need. The level of health care they may expect is conditioned by the relative wealth of the countries they live in, but the health care that is made available to some inhabitants must be made available to all inhabitants, and they must be included in the decision-making processes that establish the standards. Furthermore, there is a minimum threshold, for which the international community – or states and other in a position to assist – must indeed provide assistance. This is particularly relevant for people living in low and lower middle income countries, where governments may be unable to fulfil their minimum core obligations without international assistance.
Universal health coverage
The 2010 World Health Report describes UHC as “access to good quality health services without people experiencing financial hardship because they must pay for care” ; page ix. Since the 2010 World Health Report, the concept of UHC has gained prominence and momentum, with numerous countries making commitments to achieve it , and the 2012 UNGA Resolution endorsing it . But there is no single authoritative formulation of UHC.
The 2010 World Health Report refers to the 2005 WHA Resolution, which we consider as one of the authoritative formulations. The 2005 WHA Resolution urges member states:
“to ensure that health-financing systems include a method for prepayment of financial contributions for health care, with a view to sharing risk among the population and avoiding catastrophic health-care expenditure and impoverishment of individuals as a result of seeking care;
to ensure adequate and equitable distribution of good-quality health care infrastructures and human resources for health so that the insurees will receive equitable and good-quality health services according to the benefits package;
to ensure that external funds for specific health programmes or activities are managed and organized in a way that contributes to the development of sustainable financing mechanisms for the health system as a whole;
to plan the transition to universal coverage of their citizens so as to contribute to meeting the needs of the population for health care and improving its quality, to reducing poverty, to attaining internationally agreed development goals, including those contained in the United Nations Millennium Declaration, and to achieving health for all;
to recognize that, when managing the transition to universal coverage, each option will need to be developed within the particular macroeconomic, sociocultural and political context of each country;
to take advantage, where appropriate, of opportunities that exist for collaboration between public and private providers and health-financing organizations, under strong overall government stewardship;
to share experiences on different methods of health financing, including the development of social health-insurance schemes, and private, public, and mixed schemes, with particular reference to the institutional mechanisms that are established to address the principal functions of the health-financing system” .
The 2010 World Health Report and the 2012 WHO Discussion Paper explain UHC in three ‘dimensions’.
The first dimension is the extent of population covered under UHC. While universality ideally suggests that all people are covered, the 2010 World Health Report notes that “none of the high-income countries that are commonly said to have achieved universal coverage actually cover 100% of the population for 100% of the services available and for 100% of the cost – and with no waiting lists” , pages xv-xvi.
The second dimension addresses the financial contribution covered by the government or government-supported schemes. This can include pooled funds, prepayment schemes, increased government spending and international assistance while trying to avoid direct payments by the patients – direct payments being “charges or fees are commonly levied for consultations with health professionals, medical or investigative procedures, medicines and other supplies, and for laboratory tests” , page 5. In this dimension of UHC, the ideal is that direct payments disappear, or if they have to be maintained, then it is at a level that does not exclude people from healthcare and does not create financial hardship. However, we must take into consideration both the different socio-economic settings and groups of and within each country in progressively achieving this ideal. Some countries may be able to do away with direct payments immediately, whereas others may be able to do away with them progressively.
The third dimension of UHC as posited by WHO is the benefits in the health package. According to the 2012 WHO Discussion Paper, UHC implies that people “have access to all the services they need” (emphasis in original) . The 2012 UNGA Resolution states that UHC “implies that all people have access, without discrimination, to nationally determined sets of the needed promotive, preventive, curative and rehabilitative basic health services” (emphasis added), and acknowledges that “when managing the transition of the health system to universal coverage, each option will need to be developed within the particular epidemiological, economic, socio-cultural, political and structural context of each country in accordance with the principle of national ownership” (emphasis added) . The 2010 World Health Report, however, mentions that “[i]n lower-income countries, where prepayment structures may be underdeveloped or inefficient and where health needs are massive, there are many obstacles to raising sufficient funds through prepayment and pooling”, and that “[i]t is essential, therefore, that international donors lend their support” , page 6.
In short, under UHC, people could expect access to health facilities that provide the services they may need. As under the right to health care, the level of health care people may expect under UHC is conditioned by the relative wealth of the countries they live in – thus UHC tracks with the principle of progressive realisation. Also, UHC very explicitly aims to put an end to the discrimination that is caused by direct payments, and thus UHC affirms at least that element of the principle of non-discrimination. UHC seems to embrace the principle of cost-effectiveness as it promotes nationally determined sets of health services, developed within the epidemiological context of each country.
With regards to the principles of participatory decision-making and prioritising vulnerable or marginalised groups, UHC is less straightforward than the right to health care: the principle of national ownership advanced in the 2012 UNGA Resolution does not necessarily imply that the relevant decision-making processes will be participatory or prioritise vulnerable or marginalised groups, unless it is assumed that the national authorities duly represent the views of the people, including vulnerable and marginalised groups. The biggest difference, however, appears from comparing the right to health principles of minimum core obligations and shared responsibility with UHC. UHC – or at least the key documents we analysed to help explain the parameters of UHC – are rather ambiguous. While the 2010 World Health Report explicitly acknowledges the necessity of continued international assistance, the 2012 UNGA Resolution does not even mention international assistance among the sources of sustainable financing of UHC.
