Countries are following different paths to UHC. Some countries, mostly of middle income, in Latin America and the Caribbean (Colombia, the Dominican Republic, Mexico, and Peru, for example) have extended public insurance to nonsalaried workers, the unemployed, those out of the labor force, and the poor; these countries are making adjustments to equalize benefits across groups. Thailand has followed a similar path, beginning in 2002, and India is beginning this process. China has extended coverage of the national medical insurance program widely, but with a high co-payment and no coverage for catastrophic expenditures. LMICs in Sub-Saharan Africa (such as Ghana) face much greater resource constraints, and UHC tends to be associated with a more restricted package of services. We illustrate some of the differences and similarities among countries in their paths to UHC by considering the specific case of introducing coverage for cancer, focusing on treatment.
This section draws on case studies of eight countries: China, Colombia, the Dominican Republic , Ghana, India, Mexico, Peru, and Thailand. The four case studies from Latin America and the Caribbean are updates of earlier case studies from Atun and Knaul. Salient details for the eight countries are summarized in. Common themes and lessons emerge from these experiences. Each country faces the challenge of including chronic, catastrophic illnesses such as cancer in the package for rich and poor.
Health Insurance Coverage by Population Group
Health systems have historically built their financing schemes around sources of funding rather than health needs, often leaving the poor without access to pooled, public financing systems or opportunities for prepayment. One of the core ideas of UHC and progressive universalism is the determination to cover the poor first and relieve this group of the burden of impoverishing and catastrophic health spending.
In countries that finance their health systems through health or social insurance, salaried workers and government employees are typically the first to be covered, financed by payroll deductions supplemented by employer contributions. In many countries, this group has access to superior social security health facilities, while all other groups (nonsalaried workers, the unemployed, those outside the labor force, and agricultural workers, all of whom tend to be poorer) are limited to usually lower quality, public facilities (or those provided by nongovernmental organizations) that may have user fees and that often ration care by availability and expertise. In such cases, medication costs are frequently paid out of pocket.
The path from this pattern of segmented coverage to universal coverage has varied. Canada and many countries in Europe (the United Kingdom and the Nordic countries, for example) rely heavily on general taxation revenue to finance the system; others more strongly emphasize the contribution of private health insurance, either voluntary or mandatory (Singapore and the United States). Some countries, for example, Germany, have brought together coverage of distinct groups to reach comprehensive coverage.
The Lancet Commission on Investing in Health evaluated the extent to which the path toward increasing coverage of different groups is universal and progressive. In Latin America and the Caribbean, where health care provision has been highly segmented between those covered by social security and those not, several countries have moved to invest in publicly financed programs to extend pooled coverage, focusing on the poor and nonsalaried workers, and to reduce coverage differentials progressively.
Colombia adopted a universal social insurance plan in the 1990s, with gradual implementation, and reached universal coverage in 2011. This approach combined the contributory plan for the formal sector (including the self-employed) with coverage for the poor and the informal sector. The cost for the subsidized scheme is partly funded through general taxation, with some cross-subsidization from contributions from salaried workers and employers, with a convergence in per capita expenditures between the two sectors.
Mexico has more recently followed a similar path. The health reform of 2003 led to the Seguro Popular de Salud (SPS), which, by 2012, provided health coverage to more than 52 million Mexicans who had been ineligible for health care through the existing social security systems, with coverage of a progressively expanding number of interventions. The expansion of coverage began with the poorest segments of the population. SPS deliberately built on the platform of the anti-poverty program Oportunidades and enhanced the coverage of a package of covered services for the poor by expanding the package.
Peru’s Health Insurance Law of 2009 provided coverage for nonsalaried workers through a semi-contributory plan and for the poor through a highly subsidized plan that includes vulnerable groups, such as children and elderly persons. Salaried workers continue to be covered through a preexisting plan.
Similarly, the Dominican Republic introduced a law in 2001 (establishing the Seguro Familiar de Salud) and commenced implementation in 2007, with the aim of comprehensive coverage within a decade. As of 2013, 54 percent of the population had achieved coverage, with slightly over 54 percent of this group in the contributory scheme and the remaining 46 percent in the subsidized scheme.
Many other countries in Latin America and the Caribbean have not yet adopted pro-poor health insurance policies and programs, and coverage remains more segmented.
In the MICs of Asia included in our review, coverage is less complete than in many countries in Latin America and the Caribbean. Singapore, now an HIC, has a scheme with greater reliance on private insurance, including a separate catastrophic insurance scheme (Medishield) in addition to the mandatory regular insurance (Medisave) and the scheme for the poor (Medifund). The Singapore scheme has been held up as a good example. However, Shanghai briefly experimented with a similar model and discontinued it. The problems in Shanghai included poor control of incentives for doctors and hospitals to provide expensive treatments and extreme cases where households exhausted the limits of their insurance and were unable to pay hospital bills and bury their deceased relatives. These experiences suggest that what can work in a small, high-income urban country or city is not necessarily replicable in other settings.
Thailand passed the National Health Security Act in 2002, integrating five existing schemes and extending coverage to workers in the informal sector. The scheme covering the poor, the Voluntary Health Card, was expanded following the financial crisis in 1997.
In 2003, the Chinese government began covering rural residents and nonworking urban residents (including students, children, and elderly and disabled persons) by adding programs to existing schemes for urban public and private sector employees. This expansion increased national insurance coverage from 23 percent in 2003 to 87 percent in 2008 (72 percent of urban residents and 93 percent of rural residents) and to 97 percent by 2011. The main group remaining uncovered consists of rural migrants to urban areas, who do not have rights of residence. They are covered by medical insurance in their place of origin but do not have access to doctors where they work. The scheme for the formal sector is financed by payroll taxes; the other schemes require individual fixed contributions, supplemented by contributions from various levels of government. The local autonomy in program design has resulted in some variations in the services covered by county.
In India, as elsewhere, schemes have existed to cover salaried workers and their families. A national scheme for the poor was instituted in 2008, covering treatment up to a relatively low annual expenditure limit. However, there is no national program for informal sector workers. Some states, such as Andhra Pradesh, Karnataka, and Tamil Nadu, have developed schemes with broader entitlement.
Ghana is one of the few Sub-Saharan African countries with a national health insurance system, which was introduced in 2003. In theory, coverage is comprehensive, with payroll contributions from formal sector workers, contributions from informal sector workers on a sliding scale, contributions from the poor, and exemptions for the core poor. In practice, informal sector workers pay the minimum contribution and a small percentage of the poor is exempted from contributions. With donor contributions, the scheme ran at a deficit in 2010 and 2011. The Ghana case illustrates some of the issues facing ambitious schemes in LMICs.
Health Insurance Coverage by Services and Conditions Covered
The second dimension of coverage is breadth—by services and diseases included. All health insurance schemes have restrictions on which medical services are eligible for coverage; how these are determined crucially affects the equity and efficiency of a health system. Cost-effectiveness, population health needs, and funding should define the package of covered services. In turn, the package defines entitlement, especially once universal enrollment is achieved, which tends to become less restrictive as country income increases. A shallow package, even if it covers a large proportion of the population, is unlikely to offer protection from financial catastrophe or to lower financial barriers to accessing care, particularly for cancer.
Cancer coverage often comes later in the development of these schemes. In LMICs, coverage has tended to start with cancers that affect children and women and that are curable with access and adherence to treatment.
Poor quality of care, incomplete services, or waiting times can force many patients to seek care in the private sector and pay out of pocket, especially for medications, even though these are officially covered by insurance. Because treatment typically involves the repeated use of chemotherapeutic agents, waiting can severely reduce the effectiveness of treatment or block access entirely. Further, the package of covered services may not include components that are important for accessing or managing care, such as transport costs or medications to control symptoms. Similarly, some essential treatments or services (for example, radiotherapy) may be unavailable in the public sector, preventing patients from accessing a complete package of care. This situation can severely reduce the efficacy of the package of provided treatment.
In Colombia, for example, cancer was not included when the program started in 1994. A year later, some cancer interventions were added. Screening for four cancers was added in 2000, radiotherapy was added in 2010, and mammography and breast biopsies were added in 2012. Until 2012, fewer services were covered under the subsidized scheme than under the contributory scheme, and access to treatment has often been an issue because of geographic isolation.
Mexico has a fund for protection against catastrophic expenses that has gradually covered more cancer interventions since 2003. Initially, coverage was provided for acute lymphoblastic leukemia in children; this coverage has subsequently been extended to certain cervical, breast, and prostate cancers in adults. The package of covered services is based on cost-effectiveness criteria but includes some expensive components (breast cancer treatment, for example, includes trastuzumab for HER2-positive patients).
Peru, which has a separate fund to provide for catastrophic illnesses, launched Project Hope as part of a national cancer plan in 2012. In the Dominican Republic, coverage of cancer is at an early stage and specifies a fixed per capita sum for financial protection. The more advanced treatments are provided in the private sector; although there is some coverage from the new insurance scheme, co-payments remain relatively high (25–30 percent). New public sector facilities are under development.
In Thailand, the government has aimed to expand access to cancer treatment and, in addition to coverage, has obtained compulsory licenses for four cancer medications: letrozole, docetaxel, erlotinib, and imatinib. Thailand also has proactive policies to tax alcohol and tobacco; it uses the proceeds to help fund the Thai Health Promotion Foundation (ThaiHealth), which has been involved in comprehensive campaigns to reduce smoking.
China is at an earlier stage of expanding cancer treatment packages. The central government required local schemes to provide coverage for treatment of specified catastrophic illnesses, including six types of cancer, as of February 2013. However, because medications are not generally covered by insurance, and because of high co-payments, the extent of financial protection remains limited.
Although publicly funded insurance in India, particularly for the poor, is expanding, coverage in practice remains limited. In several states, including Andhra Pradesh, Karnataka, and Tamil Nadu, coverage is limited to third-level care and the treatments included in the packages may not be the most effective or cost-effective for the condition. Primary and secondary cancer prevention is largely piecemeal and organized by hospitals and nongovernmental organizations. However, a national program that aims to expand access to and coverage of noncommunicable disease prevention, including cancer education and screening, is in the initial stages of implementation. Several cancer drugs are available at modest cost in India, for historic reasons and because of the large domestic pharmaceutical industry, providing some relief to cancer patients.
In Sub-Saharan Africa, coverage for cancer is more limited still. The Ghana National Health Insurance Scheme is restricted to the more common and inexpensive procedures, and the only cancer coverage is for breast and cervical cancer. Ghana signed a memorandum with aid partners in 2007 to commence screening for breast cancer using mammograms; however, this screening program has not yet been implemented.
Level of Financial Protection for Cancer Services
The third dimension of coverage is whether (and how much) patients and families contribute out of pocket for services covered. Financial protection—based on prepayment, risk pooling, and public funding for the poor—is a cornerstone of efforts to achieve UHC and is the goal of many health system reforms.
Most countries recognize that public and community health services are of the highest priority and should be universally available and fully and publicly funded. Following experiences with reforms where basic public health services, such as vaccination, suffered because funding was not explicitly protected (as in Colombia), countries have developed strategies to offer protected financing for all covered interventions in this rubric. In Mexico, Seguro Popular includes a separate and protected fund. Still, it has been challenging to build into UHC the mechanisms through which these funds grow in tandem with public and community health services, especially with the availability of new interventions to treat or prevent disease. A clear example is the HPV vaccine, which is essential to the future prevention of cervical and several other cancers that are infection associated and much more common in LMICs.
Offering public financing for disease prevention and health-promoting services is important, given the importance of lifestyle and early detection in managing many cancers, including those that most burden LMICs. Patients tend to underuse these services, especially patients who are not fully informed or aware of the risks of unhealthy behavior or late detection; this underuse is exacerbated if they also face significant barriers to access.
Co-payments
The effectiveness of co-payments has been debated for decades, because any degree of co-payment can deter patients from seeking care. Further, implementing exemptions that target the poor sounds simple but, in fact, it is difficult to achieve. For these reasons, many proponents advocate the use of taxes as the more effective and equitable means of generating revenue for financing health. UHC initiatives tend to promote sliding-scale prepayments rather than co-payment at point of service.
Co-payments generally fall as country per capita income increases, but they exist even in HICs. Many LMICs, especially the poorest countries, rely heavily on co-payments. In the LICs of Sub-Saharan Africa—with some notable and recent exceptions, such as Rwanda—public resources for cancer treatment and care are severely limited and co-payments are the norm.
Co-payments often vary by type of service, being smaller (or zero) for services at facilities, but very large (even 100 percent) for medications. In China, the design varies by county, but co-payments of 60–80 percent can be required. Many countries set explicit limits on annual coverage per person or per household (for example, India’s national scheme for the poor and China), such that treatment for cancer is likely to exhaust benefits and require large out-of-pocket expenditures.
Thailand is unusual in that services provided by the government sector do not require co-payment, including prescription drugs. China has begun to identify priority diseases for the reduction of co-payments, focusing on inpatient services. As of 2013, childhood and chronic myeloid leukemia, as well as breast, cervical, lung, esophageal, gastric, and colorectal cancers, were included in these programs.
