The Singapore Model

Tuesday, May 27, 2008

The city-state of Singapore may have a fix for America’s healthcare woes.

Singapore SlingAmericans have grown used to buying every kind of product from overseas. So why not “buy” foreign ideas or social institutions? Why, for instance, hasn’t the United States adopted the same healthcare system as Europe, Canada, and nearly all the rest of the developed world? 

While the United States is portrayed as the outlier, the truth is that another developed nation has eschewed the European government-payer model—with a great deal of success. That nation is Singapore, a city-state with a population of just 4.6 million but a lot to teach America. 

Singaporeans are considerably healthier than Americans, yet pay, per person, about one-fifth of what Americans pay for their healthcare. A major reason is that Singapore’s system does not focus on the question that seems to preoccupy both Europe and America: who pays? Ultimately, whoever signs the checks, the money comes out of the pockets of individuals. Singapore takes a different tack. 

The country, a genteel and still sleepy colonial port when it became independent in 1965, was whipped into industrial shape by its founder, Lee Kuan Yew. Its detractors, opposed to his draconian style, dismissed it as a place where you could get fined for chewing gum, littering, smoking in taxis or elevators, almost anything. 

But in this election year, as Americans agonize yet again over their health service, Singapore’s system has emerged as an impressive model that is a major attraction for increasing numbers of permanent Western expatriates. 

Singaporeans are considerably healthier than Americans, yet pay, per person, about one-fifth of what Americans pay for their healthcare.

Here are some comparisons: Life expectancy at birth in the United States is 78 years; in Singapore, 82 years. The U.S. infant mortality rate is 6.4 deaths per 1,000 live births; in Singapore, just 2.3 deaths per 1,000. But the United States has far more caregivers: 2.6 physicians per 1,000 people, compared with 1.4 physicians in Singapore. The United States has 9.4 nurses per 1,000 people; Singapore, 4.2. And it has six times as many dentists as Singapore and three times as many pharmacists. 

The World Health Organization’s most recent full report on global health statistics says the United States spends 15.4 percent of its GDP on healthcare, while Singapore spends just 3.7 percent. 

What’s the reason for Singapore’s success? It’s not government spending. The state, using taxes, funds only about one-fourth of Singapore’s total health costs. Individuals and their employers pay for the rest. In fact, the latest figures show that Singapore’s government spends only $381 (all dollars in this article are U.S.) per capita on health—or one-seventh what the U.S. government spends. 

Singapore’s system requires individuals to take responsibility for their own health, and for much of their own spending on medical care. As the Health Ministry puts it, “Patients are expected to co-pay part of their medical expenses and to pay more when they demand a higher level of service. At the same time, government subsidies help to keep basic healthcare affordable.” 

The reason the system works so well is that it puts decisions in the hands of patients and doctors rather than of government bureaucrats and insurers. The state’s role is to provide a safety net for the few people unable to save enough to pay their way, to subsidize public hospitals, and to fund preventative health campaigns. 

The low proportion of government spending on health in Singapore helps the country maintain regular budget surpluses while reducing taxes. The top personal income tax rate is now 20 percent, and the corporate tax rate is 18 percent (both roughly half the U.S. rates), while the value-added tax, at 7 percent, is roughly one-third the level of the typical European country. 

The People’s Action Party has ruled Singapore since the British left, and is led today by Prime Minister Lee Hsien Loong, the son of founder Lee Kuan Yew. It calls the health system it has put in place the “3M” framework: Medisave, Medishield, and Medifund. 

Medisave, which covers about 85 percent of all Singaporeans, is a component of a mandatory pension program. Employees typically pay 20 percent of their wages into the Central Provident Fund (CPF), while employers pay 13 percent. (Since 1992, the self-employed have also participated.) At the beginning of 2007, CPF had over $1 billion in surpluses. 

In Singapore’s system, the primary role of government is to require people to save in order to meet medical expenses they don’t expect.

Medisave accounts can be used to pay directly for hospital expenses incurred by an individual or his immediate family. Limits are in place on the extent of Medisave funds that can be used for daily hospital charges, physicians’ fees, and surgical fees. The idea is to cover fully the bills of most patients in state-subsidized wards of public hospitals. Beyond that, individuals dip into their own pockets or use benefits from insurance plans (see more on this below). Medisave can also be used for expensive outpatient treatments such as chemotherapy, renal dialysis, or HIV drugs. 

Medishield, the second part of the program, is a national insurance plan that covers the higher cost of especially serious illness or accident, which in Singapore’s system is described as “catastrophic.” Singaporeans can choose Medishield or several private alternatives, some offered by firms listed on the Singaporean stock exchange. Premiums for the insurance plans, including Medishield, can be paid using Medisave accounts. 

Medifund, the third part, was established by the government for the roughly 10 percent of Singaporeans who don’t have the means to pay for their medical needs, despite the government’s subsidy of hospital and outpatient costs. The fund was set up in 1993 with $150 million, with the budget surplus providing additional contributions since then. Only interest income, not capital, may be disbursed. 

Finally, there’s Eldershield, an addition to the 3M structure that offers private insurance for disability as a result of old age. It pays a monthly cash allowance to those unable to perform three or more basic activities of daily living. 

Nearly all Singaporeans contribute directly toward each treatment, including prescription drugs, through patient co-payments of 20 percent for amounts above deductible levels. The money to meet deductibles and co-payments can come out of a person’s Medisave account. 

In Singapore’s system, the primary role of government is to require people to save in order to meet medical expenses they don’t expect. While the Singaporean government does regulate prices and services, its hand is nowhere near as heavy as that of governments with extensive nationalized healthcare, such as the United Kingdom or Germany. 

John Tucci, head of general insurance consulting for North Asia for Watson Wyatt Insurance Consulting, says, “The use of compulsory savings has been very successful as the main source of private funding for hospital expenses. 

“Another key focus of the government has been to ensure that overall health expenditure does not fall victim to the significant inflationary pressures that have been evident throughout the world. This has been achieved by regulating the supply and prices of healthcare services in the country.” Even the United States rations treatments and sets prices both through government regulation and purchasing and through private insurance rules. 

The United States spends 15.4 percent of its GDP on healthcare, while Singapore spends just 3.7 percent.

Tucci warns that it may be hard to replicate Singapore’s system in the United States. After all, Singapore has a small, concentrated population, with a “backdrop of political stability, enabling successive governments [all of the same party] to introduce consistent measures relating to individual responsibility, compulsory savings, and regulatory control of healthcare services and costs.” 

The public healthcare facilities in Singapore have been clustered, since 2002, into two integrated networks, each government-owned and managed as nonprofits: the National Healthcare Group (NHG) on the western side of the city-state, and Singapore Health Services (SingHealth) on the eastern side. Each provides a full range of services, running the public hospitals and specialty centers as private companies. 

The Health Ministry says that these clusters “provide cooperation amongst the institutions within the cluster, foster vertical integration of services, and enhance synergy and economies of scale. The friendly competition between the two clusters spurs them to innovate and improve the quality of care while ensuring that medical costs remain affordable.” 

Each of the networks also benchmarks against international standards and publishes exhaustive performance figures. In its 2007 report, NHG says its vision is “adding years of healthy life.” The goal, the report says, “departs from merely healing the sick to the more difficult but infinitely more rewarding task of preventing illness and preserving health and quality of life.” 

Meanwhile, 80 percent of primary healthcare needs are met by private general practitioners and 20 percent by public outpatient “polyclinics” of hospitals, chiefly those run by the two clusters, NHG and SingHealth. Within the private general practitioner sector, a significant proportion of patients—about 12 percent of them—consult traditional Chinese practitioners. 

Phua Kai Hong, associate professor of health policy and management at the Lee Kuan Yew School of Public Policy at the National University of Singapore, describes the crucial social setting that enabled the country to create its remarkably successful health system: a dynamic economy (with 7.5 percent GDP growth in 2007 and an average income per person of about $34,000, or three-quarters that of the United States), strong family ties and social support systems, a high propensity to save and invest, a rapidly aging and affluent population, and an absence of socialized models of social security, social insurance, or healthcare. 

He lists five core prerequisites for countries that may want to emulate Singapore’s system: a willingness and ability to save; high participation in formal employment; effective payroll collection with efficient fund management and claims processing; a well-developed information system with strong security and accounting controls; and effective public education in the proper use of medical accounts. 

Within the private-public mix, he says, most people lean toward the private system for primary care and the public system for hospital care. There are 13 public-sector specialty centers and hospitals in Singapore and 16 private-sector hospitals. But 74 percent of the beds are within the public sector. The government has also introduced low-cost community hospitals for intermediate healthcare for the convalescent and aged. 

Why does Singapore’s system work? Phua cites these principles: “the creation of incentives for responsible behavior and the efficient delivery of services; the discouragement of overconsumption through cost-sharing; the regulation of hospital beds, doctors, and the use of high-cost medical technology; the promotion of personal responsibility; targeted government subsidies; and the injection of competition through a mix of public- and private-sector providers.” 

Medical savings, he says, are now being accumulated to ensure that the Singaporean society of the future will be able to look after its own health needs even with a steady rise in the population of elderly people. 

But, he adds, there remains room for further evaluation of clinical quality and outcomes as the system continues to evolve. 

Increased investment in health facilities is encouraging a broadening of the market. More than 400,000 patients traveled to Singapore for healthcare in 2006.

While 3M was designed to curb overconsumption rather than achieve a particular public-private mix, the result of the system has been to moderate the government’s share of total health spending. The lesson here is that an efficient healthcare system will naturally come to rely on consumer, rather than government, decision-making. 

Professor Lim Meng Kin of the department of community, occupational, and family medicine at the National University of Singapore says, “Every dollar spent on healthcare is a dollar earned by healthcare providers, so there is inherently no incentive for healthcare providers to want to contain costs. Indeed, providers could be expected to exhibit entrepreneurial behavior.” 

In 1999, the system introduced case-mix—categorizing patients in order to assess the cost of treating them—as a move to address such supply-side “moral hazard.” Since 2003, the Health Ministry has been publishing hospital bill amounts for common conditions and procedures to give patients more information on which to base their choices. 

Meanwhile, the increased investment in health facilities is naturally encouraging a broadening of the market. Thus, in 2003, a group of government agencies launched SingaporeMedicine, aimed at developing the country into a leading international destination for healthcare. In 2006, more than 400,000 patients traveled to Singapore specifically for healthcare. 

This internationalization of the country’s health services is also now extending to export. Singapore hospital operator Thomson Medical Center, for instance, which specializes in obstetric and pediatric care, is establishing, with a Vietnamese partner, a 260-bed, resort-style hospital for women and children, with a medical spa and a helipad, near Ho Chi Minh City, to meet a new market arising from Vietnam’s economic surge. Many more Singaporean health providers are setting up shop in India, where they have already invested in hospitals and diagnostic centers. 

The three principal challenges, Lim says, are interrelated: containing cost, developing a medical hub, and ensuring quality. “A focus on costs without a corresponding focus on quality and patient safety is meaningless. Care that is cheap but of poor quality is surely not what Singaporeans want or deserve.” The right focus, he says, is on creating the conditions for competition, consumer choice, and provider cooperation. 

Alvin Soong, the immediate past president of the Singapore Insurance Institute, worries about rising medical inflation, which reached 6.2 percent in October—almost twice the national rate of price increases. 

“Many Singaporeans,” he says, “do not have adequate funds in their Medisave accounts to pay for their own medical bills because their Medisave funds have been used to pay the bills of spouses, parents, or siblings. The Baby Boomers have often had to take care of their parents’ medical costs.” 

He says the current average individual Medisave balance of $23,260 will not be adequate for the post-retirement period, when people most need medical coverage, even with the added protection provided by Medishield insurance. 

“After taking into account payment for the deductibles, co-insurance, and anything beyond the amount paid by the schedule of benefits...if the funds in Medisave are used to pay directly for medical bills, there may not be anything left to pay the Medishield premiums,” according to Soong. At the current rate of medical inflation, Medisave “will become totally inadequate,” he warns. 

The low proportion of government spending on health in Singapore helps the country maintain regular budget surpluses while reducing taxes.

Singapore’s health minister, Khaw Boon Wan, wants insurers to come up with more innovative policies. He says: “Give doctors and hospitals the incentive to focus on the health outcomes of your policyholders. Try piloting pay-for-performance measures that reward doctors based on the health of patients they care for, not the number of procedures performed.” His concern demonstrates that case-mix funding, intended to produce just this response, is not yet doing the trick. 

Rising health costs are not simply a matter of price increases but of more use. In 2006, operating revenues in the sector grew by 8.9 percent, the national statistics office reported in January 2008. 

As Singapore’s demography and its economy evolve, its formula for meeting medical needs will also have to change. That is hardly surprising. Nor is it surprising that it should face criticism. 

The World Bank, in a paper assessing Singapore’s health system, says the results of 3M, with its supplementary programs to protect the poor and to address potential market failures in health financing, “have been impressive, with excellent health outcomes, low costs and full consumer choice of providers and quality of care.” 

It says that Medisave—a key component of the system—could be introduced in countries without national insurance programs or well-developed private insurance, by requiring all employers and employees to set up accounts along the lines of Singapore’s program. 

In countries such as Canada and Britain which have national insurance programs funded primarily by general tax revenue, Medical Savings Accounts (MSAs) could be introduced by directly allocating a portion of existing tax revenue spent on healthcare to individuals to set up MSAs. Such governments could then progressively reduce general taxes and replace them with Singaporean-style payroll deductions allocated to MSAs. 

And, says the World Bank, in countries like the United States, with well-developed private health insurance covering basic services, consumers could be given the choice of opting for MSAs with a catastrophic-illness insurance provision instead of traditional insurance or managed care. “However, for MSAs to become truly universal, governments would have to allocate public funding—whether drawn from general tax revenue or payroll taxes—to individual MSAs.” 

Pilot programs with some MSA features have been introduced in the United States, with a focus on plans that enable employees to shift from traditional health insurance to voluntary MSAs with high-deductible health insurance. 

The critics in Singapore, unlike many in the United States, are calling for fine-tuning—not for a new engine. The structure developed 25 years ago still works. Compared with the American system, it keeps Singaporeans healthier for much less cost per person.
