| Estonia: Estonian Health Insurance Fund |
|
|
|
Estonian health care is funded through a Social Health Insurance regime where contributions are paid by salaried and self-employed workers, who contribute 13% of their wages to the system. The earmarked payroll tax is collected by the Estonian Tax and Customs Board. The tax board then transfers the health contribution to the EHIF. This system has a strong element of solidarity, as 46% of enrollees are non-contributing members and are subsidized by those who contribute. All enrollees are entitled to the same benefits package.

This system has a strong element of solidarity, as 46% of enrollees are non-contributing members and are subsidized by those who contribute. All enrollees are entitled to the same benefits package. The Estonian Health Insurance Fund is the primary financing entity. It is responsible for pooling funds, contracting with service providers, reimbursing health services and pharmaceuticals, and reimbursing sick leave and maternity benefits. In 2006, approximately 20% of EHIF expenditures went toward cash benefits such as health related work incapacity compensation, as well as dental care and prescription reimbursements. In the same year, approximately 70% of expenditures went toward payment of services such as preventative and curative health and pharmaceuticals and medical devices. EHIF also funds disease prevention and health promotion programs. Funds are disbursed to the four regional EHIF offices on a per capita basis based on the number of insured in the region. The per capita payments for primary care are adjusted based on the age structure of the region, but payments for all other health services are not adjusted. Once the regional EHIF offices receive their funds, they have some flexibility in their allocation. This is especially useful, as the planning of health service provider contracts is conducted by the regional offices. The EHIF is liable for all of its obligations, so it cannot declare bankruptcy. However, if social health insurance revenues are lower than budgeted, the state becomes responsible for the shortfall. Also, if the government establishes prices such that the EHIF cannot meet its contractual obligations, then the state becomes responsible. In order to ensure solvency, the EHIF has a cash reserve to manage daily cash flows, a legal reserve to decrease the risk of macroeconomic changes, equivalent to 6% of the budget, and a risk reserve to ensure that health insurance obligations are met, equivalent to 2% of the budget. EHIF revenues have exceeded expenditures every year since the reforms except 1999, when an economic crisis significantly reduced revenues.
Out-of-Pocket payments have been the most rapidly increasing sources of financing, increasing from 7.5% of total health financing in 1995 to 24% in 2006. OOP payments flow mainly toward cost sharing for EHIF benefits, payments for services outside of the EHIF benefits package, payments to non-EHIF providers, and to informal payments. However, the primary reason for the increase in OOP has been the dual increase in pharmaceutical use and dental care expenditures that are not a part of the benefits package. Table 1: Share of Primary Sources of Health Care Financing (1995-2006)
Source: Ministry of Social Affairs, 1999-2006 There are no copayments for family doctor visits, but other services have small copayments. Prescription drugs normally have a deductible as well as a coinsurance of percentage. Flat small copayments are charged on family doctor home visits, outpatient care visits, and hospital bed days. There has been a gradual move toward an elimination of patient cost sharing for primary care. Outpatient specialist care has a maximum consultation fee, but providers can choose to charge any amount up to the maximum. Inpatient care providers can charge a per diem rate (maximum is set by EHIF) for up to ten days. However, inpatient child care, pregnancies, and emergency care are exempt from this per diem rate.

| Ghana: National Health Insurance Scheme (NHIS) |

The NHIF is financed from several different sources. Approximately 70% of total funding comes from a health insurance levy added to VAT, 23% comes from contributions made by formal sector workers to the Social Security and National Trust (SSNIT), and 5% comes from Premium payments. Members do not pay deductibles or copayments when accessing health care. Read full sectionThe NHIF is financed from several different sources. Approximately 70% of total funding comes from a health insurance levy added to VAT, 23% comes from contributions made by formal sector workers to the Social Security and National Trust (SSNIT), and 5% comes from Premium payments. Members do not pay deductibles or copayments when accessing health care. Each funding source is described in further detail below:
The NHIS is a hybrid of social and community based health insurance models. The basic structure of the NHIS is described as a “hub-satellite” model. The “hub” of the system, which is essentially based on the SHI model of pooled public tax resources, is the National Health Insurance Fund (NHIF) which is administered by the National Health Insurance Authority (NHIA). The “satellites” are a country wide network of CBHI schemes known as District Wide Mutual Health Insurance (DWMHI) schemes which are monitored, subsidized and re-insured by the “hub.” The table below presents estimates and projections for the composition of NHIS income from 2008 to 2018.
At present, employers are not held to anything in terms of contributions other than ensuring the necessary SSNIT deductions are made from the payrolls of formal sector employees. However, the NHIC has apparently made it known that it would prefer employers to contribute a sum equal to that of the employee’s contribution. The NHIA has set the DWMHI annual premium levels at a minimum of 7.20 Ghana cedis and a maximum of 48.00 Ghana cedis (approximately $5-$34 in 2009) per adult member, to be determined by income status. The NHIA website states that this can be paid as a lump sum, or in 12 monthly installments (www.nhis.gov.gh). In practice, varying flat premiums are paid by districts across the country, with rich districts paying higher than poor districts. The recent return to power of the NDC in the 2008/2009 elections may signal a significant change in the premium structure, however. The new government is considering the possibility of instituting a one-time premium that would guarantee access to the NHIS for life. Although no definite figures have been given as yet, rumor has it that the life time premium may be in the range of 150 Ghana cedis (just over $100), although the figure of $10-12 is also heard.

The National Health Insurance Scheme (NHIS) is funded primarily by contributions from members based on income. For the Formal Sector Social Health Insurance Program contributions are premiums that make up 15% of an individual’s basic salary, with the employer contributing 10% while the employee pays 5% for coverage of themselves, their spouse, and up to 4 children. An employer may negotiate with an HMO for coverage of additional supplementary benefits and pay the extra contributions required. Participants in the Informal Sector Program are expected to make a monthly contribution based on the benefits package of their choice as well as other factors. The poor, elderly, veterans, and disabled are exempted from paying membership premiums.

The National Hospital Insurance Fund (NHIF) requires compulsory membership for all salaried employees with premium contributions automatically deducted through payroll. Contributions are calculated on a graduated scale based on income, with a majority contributing between KES 30 to KES 320 per month. For the self-employed and others in the informal sector, membership is contributory and is available for a fixed premium of 160 KES per month.

For the self-employed and others in the informal sector, membership is contributory and is available for a fixed premium of 160 KES per month. A new proposed measure has been gazetted in June 2010 that will see the first increase in premiums to the NHIF in almost two decades. This to between KES 150 to KES 2,000 per month, depending on income, with approximately 46,000 of the highest paid formal sector employees paying the maximum amount. Under this proposed change, premium payments for those in the informal sector would rise from KES 160 to KES 500 per month. Finally, under the proposed changes, other sectors of the government, development agencies, philanthropic organizations and other well-wishers would be able to purchase NHIF cover for indigent populations for a rate of KES 300 per person per month. Proposed changes are currently under judicial review and have not yet been implemented. NHIF funding and payments to providers exist alongside supply-side payments from the government directly to public sector providers. In essence, the salaries of most physicians and other health workers are still paid via supply-side payments, with NHIF payments typically going toward facility charges, drugs, supplies and consumables, and other types of overhead. Total health expenditure in Kenya, 2000 and 2006
Source: Kenya Ministry of Health, 2009 Overall, Kenya spends approximately 5% of its GDP on health. There are 3 major sources of financing for the health care system: the government (both central and local); private contributions; and donors. Donor contributions to the health sector have been steadily increasing from 8% of the health budget in 2000 to 36% in 2008. Traditionally, donor funding has been allocated directly to specific programs, limiting the flexibility of the MOH to reallocate donor assistance to fit government priorities. Public funding comes primarily from taxation, and allocations from the Ministry of Health (MOH), local governments, and parastatal organizations. Funding flows from the Ministry of Health (MOH) to the district level District Health Management Boards (DHMBs) and District Health Management Teams (DHMTs) and supplemented by local government, revolving funds, and user fees. Since the 1970s, the real financing allocations to the public sector have declined, and in 2008 the MOH only spent approximately USD $11.80 per capita, well below the WHO recommended spending level of USD $34 per capita. This lack of funding is largely because tax revenues have proven to be an unreliable source of health finance. To fill the funding gap, MOH has pursued a policy of cost sharing, which places a higher burden for financing on out-of-pocket expenditures in both absolute terms and as a percentage of the health budget. This poses a serious financing issue for the 56% of the population who are considered poor. In 2004, the government attempted to minimize cost sharing through the institution of a “10/20” policy, in which local health facilities only charge 10 or 20 KES for curative care; this has decreased out-of-pocket expenditures from 54% of THE in 2000 to about 36% in 2009.

The SP is financed by the federal government, the state government, and enrollees. The federal and state governments fund a social solidarity contribution while enrolled families contribute a premium that is tied to income. Families in the two lowest income deciles and those in the third lowest decile with a child under five years of age are not required to contribute, conditional on their participation in health promotion activities. Annual family contributions range from $60 USD for families in the third lowest decile to $950 USD for families in the highest decile. Family premiums are collected at the state level, where they remain to be used to fund the essential benefits package.

The federal and state governments fund a social solidarity contribution while enrolled families contribute a premium that is tied to income. Families in the two lowest income deciles and those in the third lowest decile with a child under five years of age are not required to contribute, conditional on their participation in health promotion activities. Annual family contributions range from $60 USD for families in the third lowest decile to $950 USD for families in the highest decile. Family premiums are collected at the state level, where they remain to be used to fund the essential benefits package. Federal funding for the SP takes the form of two distinct contributions to the states—the social contribution and the solidarity contribution. The social contribution by the federal government is a fixed allocation per enrolled family and is periodically adjusted for inflation. The SP federal contribution comes from general taxes. The federal solidarity contribution is meant to redress the large differences in development between the states. It is 1.5 times the social contribution and is generally larger for poorer states. The solidarity contribution is based on a formula that considers a per family fixed component, a health-needs adjusted component, a component aimed at promoting additional state contributions, and a component based on health system performance. The goal of this resource transfer mechanism is to make up for historical imbalances and inequities, to respond to the needs of different population groups, and to provide incentives for performance and affiliation. The formula weights and the indicators used in the formula are updated annually. The state contribution is similar in all the states, equaling approximately half of the federal social contribution. The family contribution is determined on a sliding-scale, with the goal that no family should contribute more than a fair share based on its ability to pay. Ability to pay has been defined as disposable income, which is total household spending minus spending on food. The family contribution equals a fixed proportion of disposable income, with a maximum of 5%. Income deciles three through nine have a nominal contribution, while the tenth decile has two levels of contribution due to the variable nature of the income distribution. As of 2008, 97% of families made no premium contributions. Likewise, states have also failed to pay their full share of the premium.
The framework of the reform creates certain paradoxes in its implementation. The percentage of families that are eligible to enroll in SP varies by state. The population of the northern industrialized states tends to have high levels of social security membership, whereas the population of poor southern states tends to have low levels of social security membership. This means that poor states with weak tax-based incomes must enroll a much higher percentage of their population out of state coffers compared to rich states with stronger tax bases. This appears to perpetuate inequality in health care delivery on a geographical basis. Because poorer states have the largest proportion of both the poor and the uninsured, and because the state contributions to the SP are established on a per-enrolled family basis, poorer states have to make a higher contribution than wealthier states, leading to increased geographical inequity. Therefore, federal resources are based on both a per-enrolled family fee plus a solidarity supplement for poorer states to help mitigate some of the adverse budgetary effects that stem from a large population of poor households. The National Commission for Social Protection in Health (CNPSS) has established that states must target a maximum of 30% of their resources to purchase medications, 40% to contract personnel, and 20% for activities of health promotion, early detection, and prevention. Once the requirements for the transfer of resources have been met, funds are sent to the State Finances Secretariat. Before 2007, funds were transferred directly to the State Health Secretariats. The change was established due to the reporting requirements of the State Finance Secretariats, leading to increased transparency, as well as improving the registration and use of resources at the state level. Resources are transferred to the states every three months. Since 2004, resources transferred to the Social Health Protection System have increased by an average of 11.5% annually in real terms, thereby reducing the gap between IMSS health expenditures and the expenditures of the Ministry of Health.
From 2001 to 2003, the growth rate in per capita expenditures on public health for the uninsured population averaged 5.2%. Conversely, during the first few years of the reform from 2004 to 2006, this growth rate nearly doubled to 12.3% per year. From 2001 to 2006, public expenditure for the uninsured increased by 61% overall. Since the implementation of SP, public health expenditure increased from 43.8% of total health expenditure in 2002 to 46.4% in 2006. This trend of growing public health expenditures is expected to continue. Seguro PopularFunding Primary Source of Funding: General government revenues

Resources are transferred to the states every three months. Since 2004, resources transferred to the Social Health Protection System have increased by an average of 11.5% annually in real terms, thereby reducing the gap between IMSS health expenditures and the expenditures of the Ministry of Health.
From 2001 to 2003, the growth rate in per capita expenditures on public health for the uninsured population averaged 5.2%. Conversely, during the first few years of the reform from 2004 to 2006, this growth rate nearly doubled to 12.3% per year. From 2001 to 2006, public expenditure for the uninsured increased by 61% overall. Since the implementation of SP, public health expenditure increased from 43.8% of total health expenditure in 2002 to 46.4% in 2006. This trend of growing public health expenditures is expected to continue. |
