The threat of a pandemic claiming millions of lives and devastating economies around the world is as serious as the potential perils of global climate change, renowned economist Larry Summers told a Stanford audience during a recent visit to campus.

The world is taking dramatic and costly steps to prevent the calamitous impact of climate change on the economies and national security of most countries. Yet preparations for a worldwide pandemic on the scale of the 1918 flu are vastly underfunded and ill-formed.

“My biggest fear is that the world is way short of focus on all the issues associated with pandemic,” said Summers, former treasury secretary in the Clinton administration and Harvard president emeritus, who in recent years has focused on the economics of global health care.

“We are talking about something that could kill surely tens of millions and perhaps 100 million people, and the Stanford football program is substantially more expensive than the WHO budget for pandemic flu,” he said. “It’s just crazy that we are so underinvested and underprepared.”

Summers, the Charles W. Eliot University Professor at Harvard, also served as director of the White House National Economic Council in the Obama administration. He was in conversation with Stanford Health Policy’s Paul Wise for the March 8 event co-sponsored by the Stanford Institute of Economic Policy Research for faculty and students.

The World Health Organization budget for outbreaks and crisis response has been reduced by nearly 50 percent from 2012 to 2015. Some global health experts blame these cuts in part for its slow response to the Ebola outbreak in West Africa and the ongoing Zika crisis in Brazil.

In Brazil, Zika has been linked to a spike in cases of microcephaly, a birth defect marked by small head size and underdeveloped brains. Brazil has confirmed more than 640 cases of microcephaly and is investigating an additional 4,200 suspected cases. Puerto Rico is now preparing for an expected outbreak there.

Summers said the mortality rate from the great flu pandemic was far greater than the recent Ebola outbreak in West Africa, which killed some 11,300 people mostly in Sierra Leone, Liberia and Guinea. Some 50 million people died worldwide during the 1918-1919 flu pandemic.

‘I don’t want to minimize in any way the significance of Ebola, but there are things to worry about that are vastly larger,” said Summers, who gave the keynote address for the January unveiling of the National Academy of Medicine’s report on global health risks.

That report by the Commission on a Global Health Risks Framework for the Future found that, compared with other major threats to global security, the world has “grossly underinvested” in efforts to prevent and prepare for the spread of infectious diseases. The commissioners — some 250 independent experts in health, governance and research and development — estimate $60 billion in annualized expected losses from pandemics.

“Pandemics cause devastation to human lives and livelihoods much as do wars, financial crises and climate change,” the report said. “Pandemic prevention and response, therefore, should be treated as an essential tenet of both national and global security — not just a matter of health.”

Summers estimates that pandemic flu risk is in the same range of global climate change in terms of expected costs over the next century. Yet a potential pandemic is getting only 2 percent of the attention and resources that global climate change has today.

Summers also chaired the Lancet Commission on Investing in Health, an independent group of 25 leading economists and global health experts from around the world. Their landmark report, Global Health 2035, provides a specific roadmap for this achieving “a grand convergence” in health within our lifetimes. Ahead of the U.N. General Assembly last fall, Summers led a joint declaration together with economists from 44 countries calling on world leaders to prioritize investments in health.

Wise, in the Department of Pediatrics at Stanford and senior fellow at the Freeman Spogli Institute for International Studies, asked Summers how one plans for pandemics when faced with so many failed governments and conflicts around the world.

“One of the central challenges that I worry about a lot in the deliberations of pandemic control is that many of the (regions) of greatest concern are characterized by chronic political instability, conflict and very weak governance,” said Wise, who for more than 30 years has been traveling to rural Guatemala to provide medical care to children there for his Children in Crisis project.

Summers said the world has been fortunate that there are so many brave and devoted medical workers who are trained to go into these conflict regions to try and contain outbreaks.

“But I think it would be disingenuous of me to say that you can solve these problems without in some way containing the failed state,” he said.

Wise then asked Summers what sort of advice he would give to the Stanford students who were trying to decide between a career in which one might use economics to make a fortune on Wall Street, or use economics for the greater good.

“I have always believed that you can count — and you can care,” Summers said. “There is nothing about counting and using numbers and analyzing the math that means you don’t care in a moral way.”

When a physician works with a patient and saves her life, he said, that has a profound and direct impact on both the patient and physician. But working on a vaccination program that has the potential of saving thousands of lives one day comes with delayed gratification.

“But the impact of making the world a better place and enabling people to survive and avoid grieving the loss of of a family member is as great — or greater,” he said.

What is the best way to measure returns on investments in health care?

Does the World Health Organization’s approach help developing countries allocate their limited health-care resources wisely?

What are the economic implications of the global rise in non-communicable diseases?

These are just a few of the global challenges taken up by health economics experts at the third annual Global Health Economics Consortium Colloquium at the University of California, San Francisco.

At the core of the conference is the growing field of health economics, and why cost-effectiveness analysis is fast becoming the underpinning of successful health policies.

Not only is the field expanding, so is the collaboration among researchers and faculty at Stanford Health Policy, UCSF Global Health Sciences, and the UC Berkeley School of Public Health, co-sponsors of the Feb. 12 event.

“It’s been great to see the meeting evolve from a show-and-tell to a platform where we can have nuanced discussions about the challenges and controversies in the field,” said Dhruv Kazi, an assistant professor of medicine at UCSF who helped organize and moderate the event.

Some 180 health policy experts, researchers and speakers representing 11 universities, six non-profit organizations and five for-profit outfits attended the daylong conference on the UCSF Mission Bay campus.

“By building bridges between our universities, we create a space where thought-leaders and students alike can engage in discussions to challenge working assumptions and also spearhead innovate strategies and solutions,” said James Kahn, a professor of health policy and epidemiology at UCSF and the director of the consortium.

The Consortium — known as GHECon — was awarded a five-year cooperative agreement of up to $8 million by the CDC to conduct economic modeling of disease prevention in five areas: HIV, hepatitis, sexually transmitted diseases, tuberculosis and school health.

As global economies remain turbulent, Kazi said, governments and donors have become increasingly cost-sensitive and want to better understand the societal returns they are getting for their investments in health.

“That enhances the influence of our work, but also increases the scrutiny it receives, creating an opportunity for the community to have an honest discussion about the challenges and opportunities that lie ahead,” he said. “And that is precisely the platform GHECon sees itself becoming.”

Some of the tough challenges consortium members are undertaking:

1. The World Health Organization recommends using per capita GDP as a benchmark for how much money countries should be willing to spend on health-care interventions. GHECon researchers have shown that this approach is problematic and does not always help countries allocate their limited health-care resources optimally.
2. Economic evaluations have typically only considered health-care costs, overlooking the lost income of patients or caregivers during hospital stays. GHECon researchers are working on ways to value this lost productivity in an effort to estimate the true cost of a disease and, conversely, the benefit of its alleviation. 
3. Cost-effectiveness evaluations traditionally are concerned with how efficiently health-care resources are utilized by asking questions like: How many lives can I save per million dollars invested? But society may care about other benefits that go beyond efficient use of resources, such as reducing disparities by helping the most vulnerable sections of society and alleviating poverty.

Mark Sculpher, one of the leading health economists in the world, gave the keynote address about his efforts in the UK to use cost-effectiveness analysis to inform decisions at the National Institute for Health and Care Excellence.

He said there are two big challenges today: defining cost-effectiveness thresholds that are meaningful, and determining how policymakers, donors and payers make decisions when there are multiple criteria and perspectives.

“The realities of decision-making inevitably involve a whole host of considerations,” said Sculpher, who is director of the Program on Economics Evaluation and Health Technology Assessment at the University of York. “Ultimately it’s about what is this measure of benefit that we want to maximize — and how do we invest in it.”

Stanford Health Policy’s Douglas K. Owens, director of the Center for Health Policy at the Freeman Spogli Institute for International Studies and the Center for Primary Care and Outcomes Research at the Department of Medicine, presented his influential economic modeling research about the need for routine HIV screening.

“We determined that HIV screening is cost-effective in virtually all health-care settings,” Owens told the audience, noting that the findings became policy at the Centers for Disease Control and Prevention and other national health policy organizations. It has become an example of how economic modeling can inform crucial policy decisions — and help save lives.

There were also robust panel discussions about the challenges of doing cost-effectiveness analysis in developing countries with limited resources; the difficult paths to universal health care; and how economics can help address disparities in health care and financial protection.

“The consortium is particularly valuable because it fosters collaborations among a broad group of global health experts,” Owens said.

Grant Miller, associate professor of medicine and a Stanford Health Policy core faculty member and senior fellow at the Freeman Spogli Institute, has been working to help residents of a state in India access the micronutrients that they are lacking. The work, which involves a fortified rice, includes several Indian ministries, nonprofit organizations, and faculty from across the Stanford campus to assess and support the collaborative effort.

In this video, Miller says Stanford's collaborative community and institutes help projects like his in the southeastern India state of Tamil Nadu succeed. "Micronutrient deficiency rates in Tamil Nadu are extremely high," he says. "We're working with the government of Tamil Nadu to see if it's possible to introduce fortification into what's called the public distribution system — which distributes rice at no cost to all residents of Tamil Nadu."

And, Miller says, he would not be able to carry out that research without the teamwork generated here on campus.

Stanford students belong to the first generation that could witness the end of extreme global poverty — in what would be one of humankind's greatest achievements — the head of the World Bank said during a recent talk on campus.

But their generation, he said, is also likely to experience the first global pandemic since the 1918 influenza that killed more than 50 million people.

Jim Yong Kim, president of the World Bank, said innovations in health, education and finance are behind the World Bank's twin goals of ending extreme poverty and boosting shared prosperity for the bottom 40 percent of the global population.

Speaking at the inaugural conference of the Stanford Global Development and Poverty Initiative on Oct. 29, Kim lauded faculty and students for their multidisciplinary approach in tackling poverty and improving public health. He is an infectious disease physician who oversaw World Health Organization initiatives on HIV/AIDS.

"Seeking transformative solutions to challenges of development and poverty that are necessarily cross-disciplinary is exactly what a great university should be doing," Kim said in his speech at Stanford.

The World Bank announced last month that the number of people living on less than $1.90 a day is expected to drop to 9.6 percent of the global population by the end of the year. That is down from 36 percent in 1990.

The bank has pledged to cut that rate to 3 percent by 2030.

"We expect the extreme poverty rate to drop below 10 percent for the first time in human history," he said. "This is the best news in the world today. And this is the first generation in human history that has been able to see that potential outcome." 

Promoting prosperity

One of the co-founders of Partners in Health, Kim was the keynote speaker at the daylong conference, "Shared Prosperity and Health," which drew together Stanford faculty and researchers, plus government and NGO officials from around the world.

Stanford's global development and poverty effort is a university-wide initiative of the Stanford Institute for Innovation in Developing Economies, known as Stanford Seed, and the Freeman Spogli Institute for International Studies. The conference was held at Stanford's Graduate School of Business, which was a partner in the event.

Kim's talk was optimistic about the newly adopted U.N. Sustainable Development Goals, with an ambitious agenda to end poverty and hunger, ensure healthy lives, empower women and girls and attain quality education for all children by 2030.

While those goals seem lofty, Kim pointed to the accomplishment of bringing down extreme poverty to 10 percent, a figure many had once said was impossible.

Ninety-one percent of children in developing countries now attend primary school, up from 83 percent in 2000, he said. And the number of people on antiretroviral drugs for treatment of HIV in sub-Saharan Africa has increased eightfold in the last decade.

"But we're humbled by the challenges ahead," Kim said. "Rising global temperatures will have devastating impacts on poor countries and poor people – and, as we saw with Ebola, major pandemics are likely to disproportionately affect the poor."

Pandemic threats

Kim said that most virologists and infectious disease experts are certain a pandemic will sweep the world in the next 30 years. He said that would lead to more than 30 million deaths and anywhere from 5 to 10 percent of lost GDP.

He blasted the global community for taking eight months to respond to the Ebola crisis in West Africa, noting that Guinea, Sierra Leone and Liberia had among the fastest growing economies in Africa before the outbreak killed more than 11,000 people – most of whom were poor.

In an effort to speed up financial aid the next time such an outbreak occurs, the World Bank is developing the Pandemic Emergency Facility, which would disburse funding immediately to national governments and responding agencies.

Rajiv Shah, the administrator for the U.S. Agency for International Development from 2010-2015, spoke earlier at the conference about his work leading the U.S. efforts to contain Ebola.

"Three small countries with total population of maybe 30 million people had such weak health systems with so little domestic investment – in one country $6 per capita health investment per year – that when Ebola became a crisis there was no first-line of defense," he said.

By October 2014, the U.S. was pouring hundreds of millions of dollars into containment efforts, including the establishment of a 2,500-personnel military deployment to hit Ebola on the ground. Shah said President Obama "stayed extraordinarily true to the science" of containment at the source.

Stunted children 

Moving beyond containment of epidemics, Kim said the most important investment developing countries could make in their people starts when a woman becomes pregnant. Using a combination of health, nutrition and education will have lifelong benefits for each child, as well as for the country in which each prospers.

The World Bank estimates that 26 percent of all children under age 5 in developing countries are stunted, which means they are malnourished and under-stimulated, risking a loss of cognitive abilities that lasts a lifetime. The number climbs to 36 percent in sub-Saharan Africa, giving those children limited prospects in life."This is a disgrace, a global scandal and, in my view, akin to a medical emergency," Kim said. "Children who are stunted by age 5 will not have an equal opportunity in life. If your brain won't let you learn and adapt in a fast-changing world, you won't prosper and, neither will society. All of us lose."

From 2001 to 2013, the World Bank invested $3.3 billion in early childhood development programs in poor countries. Kim said innovative policymaking and financial tools allowed the bank to help Peru cut its rate of child stunting in half to 14 percent in just eight years.

"Progress is possible – and it can happen quickly. But we must do even more,"he said.

Kim said the world set a target in 2012 to reduce stunting in children by 40 percent. But that would still leave 100 million children malnourished and undereducated. The bank and world leaders should pledge to end stunting for all children by 2030, he said.

"With partners like the Global Development and Poverty Initiative and the entire Stanford community, I'm full of hope that we can indeed be the first generation in human history to end extreme poverty and create a more just and prosperous world for everyone on the planet."
