Elderly patients hospitalized with congestive heart failure have a poor prognosis and high risk of death and hospital readmission. So, their post-discharge care can strongly influence their outcomes.

Yet despite data showing that transitional care interventions, such as home visits by nurses, can reduce death rates and hospital readmission by more than 30%, many health systems have not implemented such programs. Health policy experts say this is due in part to cost concerns and doubts about the effectiveness of these delivery services.

 Now, a team of Stanford Medicine and Veterans Affairs researchers has sought to assess whether transitional care interventions provide good value and better outcomes, as there are 5 million people living with congestive heart failure in the United States and 500,000 new cases diagnosed each year. CHF is the stage of chronic heart disease in which fluids build up around the heart, causing it to pump inefficiently.

The researchers updated a 2017 study on the impact of transitional care intervention with four years of additional data. They then used it to compare standard post-discharge management with three post-discharge regimes for patients 75 or older that they found to be most effective: disease management clinics, nurse home visits and nurse case management.

All three transitional care interventions delivered appreciable health benefits to the patient population, said Jeremy Goldhaber-Fiebert, PhD, associate professor of medicine at the Stanford School of Medicine and core faculty member of Stanford Health Policy.

The findings were published in the Annals of International Medicine. Goldhaber-Fiebert is the senior author. The lead authors are Manuel R. Blum, MD, MS in Epidemiology & Clinical Research at Stanford in 2019 and now at the Department of General Internal Medicine at the University Hospital of Bern; Henning Øien, PhD, Norwegian Institute of Public Health, Oslo; and Harris L. Carmichael, MD, a Stanford/Intermountain Fellow in Population Health, Delivery Science, and Primary Care

“Transitional care interventions for older individuals with congestive heart failure — particularly nurse home visits — offer a high-value care alternative that could improve the health and longevity of millions of Americans,” he said.

The researchers said these transitional care services should become the standard of care for post-discharge management of patients with heart failure.

Heart failure causes 1 in 8 deaths nationwide

The prevalence of heart failure is estimated to be 26 million people worldwide and growing. In the United states, heart 5.7 million adults have been diagnosed with HF, with an estimated annual direct cost of $39.2 billion to $60 billion. Total heart failure costs in the United States are expected to exceed $70 billion by 2030, the authors wrote. According to the Centers for Disease Control and Prevention, heart disease costs the United States about $219 billion each year from health-care services, medicines and lost productivity.

Of the 15 million Americans in their mid-70s to 80s today, about 1 million suffer heart failure.

“So population gains from more effective post-discharge care would be hundreds of thousands of life years,” Goldhaber-Fiebert said. “Likewise, tens of thousands of costly rehospitalizations could be prevented each year if these interventions were delivered successfully.”

Heart failure primarily affects older people and is the second-most common inpatient diagnosis billed to Medicare. Yet the authors cite a recent study of 18 million Medicaid charges which found that only 7% of eligible patients at risk of rehospitalization received transitional services.

The standard post-hospital care for those patients includes sending them home with some advice and scheduling follow-up visits for them with cardiologists within 14 days of discharge. The researchers found that patients who received this standard post-hospitalization care with an average age of 75 had an average life expectancy of 2.9 years and 2.9 hospitalizations during their remaining lifetime. In comparison, nurse home visits decreased the number of hospitalizations by 10 readmissions per 100 patients and increased life expectancy by approximately four months, the study found.

“If these interventions were successfully implemented at scale, they could provide important substantial benefits with very good value,” said co-author Douglas Owens, MD, the Henry J. Kaiser Jr. Professor and professor of medicine at Stanford.

Reduced hospitalizations for congestive heart failure, according to the research, produces substantial cost savings that partially offset the costs of delivering the interventions. Though nurse home visits increase lifetime health care costs by $4,622, the substantial health benefits that they deliver justify their costs: $19,570 quality adjusted life years gained, which is considered highly cost-effective.

Hospital and insurance administrators take note

“Our results have important implications for decision-makers in hospital administration as well as in insurance and policy settings,” the authors wrote. They concluded:

• Transitional care services should become the standard of care for post-discharge management of patients with heart failure;
• The increasing reimbursement restrictions and regulations affecting HF hospital readmissions, through such programs as the Centers for Medicare & Medicaid Services Hospital Readmission Reduction Program, makes this research particularly informative to decision-makers;
• Hospital administrators could use the research to determine which transitional services are most cost-effective for its rural population, overall patient base and hospital system.

Stanford Health Policy researchers, led by Josh Salomon, have been awarded a five-year grant from the Centers for Disease Control and Prevention (CDC) to conduct health and economic modeling to guide national and local policies and programs focusing on some of the most important infectious diseases in the United States.

The CDC grant establishes the Prevention Policy Modeling Lab at Stanford, continuing a multi-institution collaboration that began when Salomon was a professor at Harvard prior to joining Stanford in 2017.

“The overall mission of the Prevention Policy Modeling Lab is to leverage the best available evidence to inform strategic decision-making about major public health problems,” Salomon said. “We do this by combining techniques from decision science, simulation modeling and health economics to estimate and project major patterns and trends in these diseases and to evaluate different clinical and public health strategies to address them.”

The initiative will focus on policy and practice in the areas of tuberculosis, HIV, hepatitis, sexually transmitted infections and adolescent health. The grant from the Centers for Disease Control and Prevention supports a wide range of modeling activities, including those that assess: 

• Projections of future morbidity and mortality
• Burden and costs of diseases
• Costs and cost-effectiveness of interventions
• Population-level program impact
• Optimized resource allocation

Stanford researchers who are involved in the Modeling Lab include Douglas K. Owens, Margaret Brandeau, Eran Bendavid, Jeremy Goldhaber-Fiebert, Jason Andrews, Samuel So and Mehlika Toy. The consortium also includes partners at Harvard, Yale, Michigan, Boston University, Boston Medical Center and the MA Department of Public Health.

“As a multi-institution consortium, on any given problem we’re able to assemble a team that includes both subject matter experts and collaborators who specialize in statistics, epidemiology, data science, economics and decision analysis,” Salomon said. “The policy models that we develop allow us to synthesize a wide array of different types and sources of evidence to shed light on the essence of the problem and to weigh the likely benefits and costs of responding in different ways.”

Prior work from the consortium on the potential impact and cost-effectiveness of expanding testing for hepatitis C virus was cited in the recent decision by the U.S. Preventive Services Task Force to revise their screening recommendations to cover all adults. The Modeling Lab has also examined prospects and strategies for eliminaitng tuberculosis in the United States and policies relevant to the rising threat of antimicrobial-resistant gonococcal infection among other topics.

Understanding the value of chronic disease care is critical to confronting the challenges of aging societies. In a new ebook published by the Centre for Economic Policy Research, APARC Deputy Director and Asia Health Policy Program Director Karen Eggleston provides a framework for assessing the social value of health spending.

The world population is aging faster than ever before and governments must confront the increasing burden of healthcare spending on their economies. At a time when the economics of aging is inseparable from the economics of healthcare, successful adaptations to older population age structures necessitate better understanding of the value of medical care. Policymakers, in particular, must incorporate value into considerations of healthcare cost growth, so they can determine the extent to which average health improvements offset added cost, reduce cases in which health spending rises without sufficient corresponding health outcomes, and reward those in which “we are getting what we pay for.”

A new book chapter, authored by APARC Deputy Director and Asia Health Policy Program Director Karen Eggleston, provides a framework for assessing the social value of health spending. Titled “Understanding ‘value for money’ in healthy aging,” the chapter is part of an ebook, Live Long and Prosper? The Economics of Ageing, published by the Centre for Economic Policy Research (CEPR).

Quality-Adjusted Cost of Care

How do health economists incorporate value into measurements of health spending and how do they measure the social value of medical care? First they assume each additional year of life brings a given monetary value. Then they measure the growth in value to patients as monetized gains in “quality-adjusted life-years,” a metric that includes increases in life expectancy and quality of life. The difference between the change in health spending and the change in monetized gains on improved survival is the net change in quality-adjusted health spending or the net value of medical care.

Understanding the value of chronic disease care is especially critical in aging societies, as governments must transform their health systems to support patients who will live with chronic diseases for decades. Health benefits of medical care, however, are difficult to aggregate across disparate services and diseases, and hence focusing on management of a single important chronic disease allows researchers to develop metrics of quality improvement and value that are linked to rigorous clinical studies. Eggleston describes a recent international research collaboration, which she was part of, that did just that. The researchers studied quality adjustment for one disease of growing global prevalence, type 2 diabetes, in four different health systems: one in Europe (the Netherlands) and three in East Asia (Japan, Hong Kong, and Taiwan).

Results of the study suggest that, in each health system, the value of improved survival outweighs the increase in health spending. For example, in the case of Japan, Eggleston and her colleagues found a positive value net of $2,595 for $100,000 value of a life-year. They also compared net value across the four health systems and different patient samples, finding mean net value that ranged between $600 and $10,000 for a $100,000 value of a life-year. Moreover, net value was positive for all age groups and remains positive and significant for individuals well beyond traditional retirement ages. These results, says Eggleston, indicate “the importance of continuing investments in medical treatments and services that deliver health outcomes of commensurate or higher value.”

Policy Implications

Confronting the challenges of aging societies requires careful thinking about the value of investments in new technologies for managing chronic conditions. To promote healthy aging governments must be “resiliently persistent in measuring the value of innovations for healthy aging and rewarding those that deliver high net value,” argues Eggleston. The goal should be improving the “value for money” of medical care rather than applying largescale cost controls that might stifle important breakthroughs.

The four-system study by Eggleston and her colleagues provides a framework for developing methods for assessing quality improvement and the net value of chronic disease spending and, more broadly, for measuring the value of healthy aging.

In a new article published by the Milken Institute Review, APARC Deputy Director and Asia Health Policy Program Director Karen Eggleston offers an overview of the successes of China’s health reforms and the challenges ahead if the country is to increase the efficiency of health care delivery as it expands quality and usage.

Creating a high-quality universal health care system is an immense challenge anywhere, let alone in a country as large and diverse as China. But equal access to care will become ever more important as China converges on higher incomes, slower economic growth, population aging, and dependence on a skilled workforce to approach OECD living standards. With its health reforms over the past two decades, its growing technological prowess, and its application of innovative business models, China has made significant progress towards supporting higher-quality and more convenient health care for its 1.4 billion people. However, it is yet to deal with a host of challenges.

In a new article, Healing One-Fifth of Humanity, published in fall quarter 2019 of the Milken Institute Review, APARC Deputy Director and Asia Health Policy Program Director Karen Eggleston offers a progress report on China’s efforts to provide decent health care to all of its citizens, detailing how the reforms are working and what is left to do.

A Tale of Two Chinas

One complex challenge China faces is addressing the gap in living standards between its rising middle class and its poorest citizens. Eggleston’s research shows stark gaps between urban and rural China in multiple measures, including life expectancy (almost 10 years differences as of 2013), infant mortality, and under-age-5 mortality. Health outcomes differ along other dimensions, too — between urban regions with higher and lower per capita income and among individuals with more or fewer years of schooling.

There are also striking inequalities in the burden of chronic disease and in health care and risk protection. For example, diabetes is associated with greater excess mortality in rural China, although prevalence is higher in urban areas. Moreover, although China has attained universal health coverage and put in place policies to enhance access while decreasing households’ out-of-pocket spending burden, the coverage of rural insurance is less generous than coverage for urbanites. Therefore, the prospect of catastrophic medical spending on delayed care remains substantially higher for rural than urban residents.

Additional challenges abound in multiple other areas, from addressing patient-provider tensions and trust, to changing provider incentives to promote value rather than volume, to deciding which new medical therapies qualify as basic. In broad terms, argues Eggleston, “China must build an infrastructure that increases the efficiency of health care delivery as it expands quality and usage.”

An important issue is the extent to which leveling public policy will ameliorate disparities, even as an array of social and economic forces push to widen disparities in health, health care use and burden of medical spending over a lifetime. The good news, says Eggleston, is that the process of catching up on one critical component of social justice, that is, universal health care, has begun, and there is evidence suggesting “that health investments can narrow the gaps in outcomes by compensating for health disadvantages.” There is also good reason to believe that policies that go beyond direct medical intervention – notably, investments in the quantity and quality of schooling – can have even greater influence on health and survival than access to medical care.

“The challenge now,” concludes Eggleston, “is to persist in an endeavor that requires flexibility, sensitivity to competing interests — and lots and lots of money.”

When it comes to rooting out wasteful spending in federal entitlement programs, attention has long focused on preventing beneficiaries from gaming the system.

A new Stanford study identifies a fresh cause for concern: the for-profit companies that the U.S. government increasingly tasks with providing benefits to Americans who are often poor, elderly or both.

In a new working paper, Maria Polyakova, an assistant professor of medicine, finds that outsourcing public assistance services to third parties can lead to unanticipated effects on prices as well as on which beneficiaries gain the most from public dollars.

That’s because companies are in the business of making money. And when they know which of their consumers are likely to get certain levels of public support, they will try to use this information to maximize their profits, according to the research published this week by the National Bureau of Economic Research.

Polyakova shows that when companies act in their self-interest, unforeseen inequities and inefficiencies can arise that may hurt some consumers while helping others. At a time when governments in the United States and around the world are increasingly turning to the private sector to provide public benefits — namely in health care and in education — Polyakova says policymakers need to better understand how these intermediaries are affecting welfare programs.

“Policymakers have to be more careful about introducing intermediaries into public services,” says Polyakova, who is a faculty fellow at the Stanford Institute for Economic Policy Research (SIEPR), and teaches at the Stanford School of Medicine. She is also a core faculty member of Stanford Health Policy. “They may want to revisit how they think about outsourcing when research is showing that there are unintended consequences that may be positive or negative.”

Health Insurance Pricing under the Microscope

Intermediaries are central to a number of public services where the U.S. government provides subsidies to consumers, often based on income, age or employment status. Prominent examples include privately-managed Medicare Advantage Plans, drug benefits under Medicare Plan D, and charter schools in secondary education.

According to Polyakova, most research into wasteful spending within government subsidies has focused on consumers and how they try to trick the system by, for example, hiding income to qualify for a tax credit or cash assistance. Governments, though imperfect, have long been seen as benign players.

The increasing involvement of for-profit companies, she says, shows there’s a need to closely examine what’s happening on the supply side of public welfare.

To do that, Polyakova found an ideal setting: the federal health insurance marketplace created by the Affordable Care Act of 2010. Most consumers who shop for coverage through www.healthcare.gov receive a subsidy in the form of a tax credit that covers all or part of their insurance premium. The amount of their tax credit is tied to their household income.

The dollars at stake are significant. The Congressional Budget Office estimates that in 2019 the federal government will pay $560 billion in subsidies for privately-provided health insurance, including the spending on the Affordable Care Act marketplaces as well as other similarly designed programs. That figure is expected to hit $1.2 trillion over the next decade.

The Neighborhood Effect

Polyakova and her co-author — Stephen Ryan of Washington University’s Olin Business School — analyzed data from 2017 covering more than 9 million enrollees across some 2,570 counties around the country. They find that the presence of an intermediary significantly impacts insurance prices and key measures economists use to calculate the effects of a policy beyond a given benefit’s face value.

Specifically, they show that health insurance companies will have an incentive to raise premiums in markets where more consumers receive the higher tax credit because their incomes are low and the government is required to subsidize them.

On the flip side, insurers will charge lower prices in places where such subsidized consumers are less willing to buy coverage if they think it costs too much.

To illustrate the unintended consequences of the insurers’ actions, the researchers point out that, in the first instance where prices increase, consumers with incomes that are slightly higher than other community members will end up paying more for the same coverage. Under the second scenario, consumers who don’t qualify for the tax credit because their incomes are too high benefit from the lower premiums aimed at nearby residents.

“The price you pay for insurance will depend on who your neighbors are,” says Polyakova. “If you live near people who are poorer than you, you will be affected differently than if you live near people who are richer than you.”

Change the subsidy, change the calculation

Like with financial aid, tax credits for insurance coverage are calculated based on consumer income. But there is another type of subsidy that policymakers could use — flat vouchers, in which all members of a market receive the same benefit regardless of income, age or some other characteristic. For their research, Polyakova and Ryan also analyze how flat vouchers that only vary by age, but not by income, would hypothetically alter private health insurance prices in the federal Affordable Care Act marketplace.

Here, too, the scholars find different impacts on different types of consumers whether the subsidy is based on income or delivered as a flat voucher.

The analyses, says Polyakova, drive home the point that policymakers need to understand that there are trade-offs to relying on for-profit companies to provide government services and that the type of subsidy offered can alter how they calculate prices in disparate ways.

“There’s nothing wrong with companies trying to maximize their profits,” says Polyakova. “But sophisticated policymakers need to understand what happens when private markets get involved.”

Global warming and more days of extreme heat are exacerbating the health risks of pregnancy, particularly among African-American women, according to new Stanford-led research.

The maternal mortality rate among all women in the United States is already the worst of any industrialized nation. And black women are three to four times more likely to die from pregnancy-related problems than white women.

“It is truly a crisis that in America, one of the wealthiest countries in the world, more women are dying from pregnancy or childbirth complications than in any other developed country,” said Maya Rossin-Slater, a core faculty member at Stanford Health Policy and a faculty fellow at the Stanford Institute for Economic Policy Research.

In a new working paper published by the National Bureau of Economic Research, Rossin-Slater and two other health economists underscore how little research is out there about the impact of rising temperatures on the health of mothers and their newborns.

Pregnant women, for example, are not able to regulate body temperature as efficiently as non-pregnant individuals due to the physiological changes they undergo during gestation. Heat exposure can alter blood flow in the placenta, which can weaken the placenta and lead to complications. And high heat can lead to other pregnancy complications, such as hypertension, preeclampsia and prolonged premature rupture of membranes.

“All of these issues can translate into women needing to be hospitalized during pregnancy and experiencing complications during childbirth,” wrote Rossin-Slater, an assistant professor of health research and policy at Stanford Medicine. Her co-authors are Jiyoon Kim, assistant professor of economics at Elon University, and Ajin Lee, an assistant professor of economics at Michigan State University.

The researchers said most of the discussion about maternal health focuses on the health-care system, but that other determinants of poor maternal health and racial disparities are much less understood, particularly when it comes to how the environment is impacting pregnancy.

So they launched what they believe is the first study to identify the causal effects of prenatal exposures to extreme temperatures on the health of the mothers themselves.

As the Earth Warms, So Does Exposure to Extreme Heat

Their paper focuses on an environmental factor that is becoming increasingly relevant due to the growing consensus that climate change is contributing to a gradual warming of the earth: exposure to extreme heat.

The researchers studied the effects of exposure to extreme temperatures during pregnancy on maternal and child hospitalizations, using inpatient discharge records from three U.S. states with different climates: Arizona, New York and Washington. Their data comes from the State Inpatient Databases from the Healthcare Cost and Utilization Project, including 2.7 million inpatient records of 2.7 million infants and 2.2 million mothers in those three states.

And to measure temperature exposure, the researchers obtained data from the National Oceanic and Atmospheric Administration (NOAA).

For every county in their data, the researchers calculated the average temperature for every month. Then for every given day in a specific month in that county, they looked at the historic average for how high or low that day’s temperature was relative to the overall temperature in that month in that county.

For example, a 90-degree day in Arizona in September would not be classified as extreme heat since it’s relatively common. But a 90-degree day in New York would be, since temperatures that high are much less common. They classified “extreme heat” as a given day when the temperature is more than three standard deviations (3SD) above that historic county mean.

Then, they compared the outcomes of women who are of the same race giving birth in the same county and calendar month, but in different years. These women are likely similar in terms of their demographics and socioeconomic status, but may be exposed to different temperatures during pregnancy. For example, consider a black woman giving birth in November 2011 in Queens County, New York, and a black woman giving birth in November 2012 in the same county. If there were a heat wave in Queens in the August 2012, then the latter woman is exposed to more extreme heat during pregnancy than the former. 

The economists found that each additional day with heat that is at least 3SDs — or substantially higher than the historic county-month average — during the second trimester of pregnancy increases the likelihood that a newborn is diagnosed with dehydration by .008 percentage points.

“Our results provide new estimates of the health costs of climate change and identify environmental drivers of the black-white maternal health gap,” they wrote. “Understanding the health consequences of this increase in extreme heat is critical information for discussions about the costs of climate change and the possible benefits of mitigating policies.”

The researchers found that each additional day of extreme heat exposure during pregnancy increases black women’s likelihood of hospitalization during pregnancy. Since black women on average are exposed to more extreme heat than white women — due to different residence patterns and access to mitigating technologies like air conditioning — extreme heat may contribute to exacerbating the already large gap in maternal health between black and white women.

Detrimental Consequences of Rising Temperatures

Scientists predict global average temperatures will continue to rise over the next 50 to 100 years as greenhouse gases continue to trap more heat in the Earth’s atmosphere. The U.N. Intergovernmental Panel on Climate Change last year warned that nations worldwide must quickly reduce fossil fuel use to keep the rise in global temperatures below 1.5°C by 2050. 

The panel also said the number of days with mean temperatures above 32°C in the average American county is forecasted to increase from about 1 to 43 days per year by 2070-2099.

That could have detrimental consequences for babies and mothers alike.

“Overall, our findings on infant health suggest that exposure to extreme heat during the second trimester increases the likelihood of the baby being dehydrated at the time of birth,” the researchers wrote. “This, in turn, appears to increase the likelihood of subsequent readmission to the hospital many months later for causes linked to dehydration.”

And these impacts are typically missed when researchers only measure infant health using more standard variables, such as birth weight.

The authors note dehydration is one of the leading causes of morbidity and mortality in children. Studies show that children under 5 years old who have an average of two episodes of gastroenteritis associated with dehydration per year leads to 2 to 3 million pediatric office visits and accounts for 10% of all pediatric hospital admissions in the United States. 

Experts believe black women are three- to four-times more likely to die from pregnancy-related causes due to lack of access to and the poor quality of health care, as well as clinicians not monitoring black women as closely — or actually dismissing their symptoms altogether.

“The fact that the adverse impacts on health during pregnancy are larger for black than for white mothers suggests that climate change may exacerbate the already large racial gap in maternal health,” the researchers said.

I always find it hard to believe so many people are living in poverty: some 39.7 million Americans, or 12.3% of the population. It’s such a wealthy country, yet so many are poor.

In a twist that could be interpreted as good news — it doesn’t seem fair to say there is anything positive about living in poverty — I recently learned that older, low-income Americans tend to be healthier if they live in more affluent areas of the country.

Not only are they healthier, but their physical well-being is better across the board with a lower prevalence of dozens of chronic conditions, particularly if they live in rural communities. This, despite their income having less purchasing power in those better-resourced neighborhoods.

This was the key finding in new research published by Stanford Health Policy’s Maria Polyakova in the Annals of Internal Medicine.

While recent studies have reported that low-income adults living in more affluent areas of the United States have longer life expectancies, less has been known about the relationship between the affluence of a geographic area and morbidity of the low-income population.

“I was interested in figuring out whether the same relationship holds for morbidity: Are poorer people less sick in richer areas?” Polyakova told me. “And if so, are there any specific conditions that drive these differences that could be the target for policy-making?”

So Polyakova, a faculty fellow at the Stanford Institute for Economic Policy Research, and her co-author, Lynn M. Hua at the University of Pennsylvania, set out to evaluate the association between chronic conditions among low-income, older adults and the economic affluence of a local area. 

They focused on nearly 6.4 million Medicare beneficiaries in 2015 aged 66 to 100 years old who received low-income support under Medicare Part D, a prescription drug program for Medicare enrollees. They investigated the prevalence of 48 chronic conditions among these patients, including common chronic conditions such as hypertension, depression, diabetes and Alzheimer’s disease. They found the presence of all conditions is highly correlated: places, where the poor tend to have a high prevalence of one disease, are likely to have a high prevalence of all 48 conditions.

“While we cannot ascertain a causal relationship, our results clearly point towards the importance of further understanding why the socioeconomic environment of low-income, older adults is so tightly linked to such a broad measure of health,” the researchers wrote. 

The results, they said, were broadly consistent with the extensive literature on the social determinants of health. But their work takes that literature even further.

“Our study extends this research by providing measures of the prevalence of chronic conditions among low-income, older adults for a large national sample of the U.S. population,” Polyakova said. 

The researchers used clinical, rather than self-reported measures of diagnoses and reported this group’s variation in morbidity across local areas of the country, rather than nationally. 

“Our results raise the bar for researchers who are trying to find out what factors drive health disparities in the U.S.; these factors would have to be able to explain the differences in nearly 50 condition,” Polyakova said.

The study supported by the National Institute on Aging came to three key conclusions:

1. The health of low-income, older adults in the United States varies substantially across local geographic regions, and this variation cannot be attributed to one specific disease or a narrow set of conditions. 
2. Consistent with their original hypothesis, they found that more affluent local areas of the country have a lower prevalence of chronic conditions in the low-income, older adult population.
3. The researchers found that low-income, older adults have better health in rural areas of the country.

I wondered why these poor, older adults do particularly well in rural communities, as those regions often lack easy access to high-quality health care and state-of-the-art hospitals.

“We don’t know the exact answer, but there is a general sense that differences in the social fabric and lifestyle in rural areas — could contribute to this pattern,” Polyakova told me. “It appears that better health in these areas persists, despite challenges of accessing formal care.”

A task force of national health experts has released a draft recommendation to screen all adults 18 to 79 years for the hepatitis C virus (HCV), noting the opioid epidemic has fueled what has become the most common chronic bloodborne pathogen in the United States.

Cases of acute HCV have increased 3.5-fold over the last decade, particularly among young, white, injection drug users who live in rural areas. Women aged 15 to 44 have also been hit hard by the virus that is spread through contaminated blood.

The U.S. Preventive Services Task Force, which makes recommendations followed by primary care clinicians nationwide, has until now recommended that people who are at high risk be tested for hepatitis C, as well as “baby boomers” born between 1945 and 1965.

“Unfortunately, HCV now affects a broader age range than previously with three times as many new infections per year,” said Stanford Health Policy’s Douglas K. Owens, chair of the independent, voluntary panel of national experts in prevention and evidence-based medicine.

The Task Force now recommends that clinicians encourage all their adult patients, even those with no symptoms or known liver disease, get a blood test for the virus. Pregnant women should also be screened; from 2009 to 2014, the prevalence of HCV infection among women giving birth has nearly doubled.

“The explosive growth in HCV has been fueled by the opioid epidemic, with the spread of HCV into younger populations,” said Owens, director of the Center for Health Policy and the Center for Primary Care and Outcomes Research. “HCV now kills more Americans than all other reportable infectious diseases combined, including HIV.”

An estimated 4.1 million people in the United States are carrying HCV antibodies; about 2.4 million are living with the virus, according to the Task Force. The HCV infection becomes chronic in 75% to 85% of cases and some of those people develop symptoms such as chronic fatigue and depression, and liver diseases that can range from cirrhosis to liver cancer.

Approximately one-third of people ages 18 to 30 who inject drugs are infected with the virus; 70% to 90% of older injection-drug users are infected.

There currently is no vaccine for hepatitis C although research in the development of a vaccine is underway. But there are effective oral direct-acting antiviral (DAA) medications that can clear the virus from the body, particularly if caught early.

“The good news is that treatment for HCV is far better, and far better tolerated than in the past, offering a cure to most people,” Owens said. “Early identification of HCV is important to prevent long-term complications of HCV including liver failure, liver cancer, and death.”

The Task Force said in a release that there are several key research gaps that could inform the benefit of screening for HCV infection:

1. ·     Research is needed on the yield of repeat vs. one-time screening for HCV.
2. ·     Research is needed to identify labor management practices and treatment of HCV infection prior to pregnancy to reduce the risk of mother-to-child transmission.
3. ·     Trials and cohort studies that measure effects on quality of life, function, and extrahepatic effects of HCV infection (such as renal function, cardiovascular effects or diabetes) would be helpful for evaluating the impact of DAA regimens on short-term health outcomes.
4. ·     Additional studies are needed to examine the epidemiology of HCV infection and the effectiveness of DAA regimens in adolescents.

A U.S. foreign policy that cuts money to nongovernmental organizations performing or promoting abortions abroad has actually led to an increase in abortions, according to Stanford researchers who have conducted the most comprehensive academic study of the policy’s impact.

Eran Bendavid and Grant Miller — both associate professors at Stanford University School of Medicine and core faculty members at Stanford Health Policy — and doctoral candidate Nina Brooks find that abortions increased among women living in African countries where NGOs, such as the International Planned Parenthood Federation, were most vulnerable to the policy’s requirements.

The policy, widely known as the Mexico City Policy, explicitly prohibits U.S. foreign aid from flowing to any NGO that will not abide by the policy’s main condition: no performing or discussing abortion as a method of family planning, even if just in the form of education or counseling.

The policy has been a political hot potato since its inception. Enacted under Ronald Reagan in 1984, it’s been enforced by subsequent Republican administrations while Democrats in the White House revoked the policy within days of taking office.

The study by Brooks, Bendavid and Miller, published June 27 in The Lancet Global Health, looked at the policy’s effects in more than two dozen African countries over a span of 20 years under three presidents: Bill Clinton, George W. Bush and Barack Obama. It finds that, when the policy was in place during the Bush years, abortions were 40 percent higher relative to the Clinton and Obama administrations.

When the policy was suspended during Obama’s two terms, the research shows that the upward trend in abortion rates reversed.

“Our research suggests that a policy that is supported by taxpayers ostensibly wishing to drive down abortion rates worldwide does the opposite,” said Bendavid, a faculty affiliate of the Stanford King Center on Global Development, which is part of the Stanford Institute for Economic Policy Research (SIEPR).

A key reason for the uptick in abortions is that many NGOs affected by the policy also provide contraceptives – and funding cuts mean birth control is harder to get, said Brooks.

“By undercutting the ability to supply modern contraceptives, the unintended consequence is that abortion rates increase,” she said.

And the policy’s scope has expanded under the Trump administration. While it originally restricted aid directed only toward providing family planning and reproductive health services, President Trump has extended the policy to cover any group engaged in global health, including organizations providing services for HIV or child health – not just family planning.

Groundbreaking Research

The stakes are high. America is the world’s largest provider of development assistance and spent about $7 billion on international health aid in 2017. Many women in sub-Saharan Africa depend on this aid for contraceptives.

In sub-Saharan Africa, NGOs are often primary providers of family planning services. Two of the world’s largest family planning organizations – International Planned Parenthood Federation and Marie Stopes International – have forfeited large sums of U.S. cash for refusing to comply with the policy, according to news reports.

The research findings were based on records of nearly 750,000 women in 26 sub-Saharan African countries from 1995 to 2014. When the policy was in effect under George W. Bush, contraceptive use fell by 14 percent, pregnancies rose by 12 percent and abortions rose by 40 percent relative to the Clinton and subsequent Obama years – an impact sharply timed with the policy and in proportion to the importance of foreign assistance across sub-Saharan Africa.

The paper is the second study of the rule’s impact by Bendavid and Miller, who are both faculty members of Stanford Health Policy. The research is also one of the very few evidence-based analyses of the policy.

Their earlier research, the first quantitative, large-scale effort to examine the policy’s impacts, looked at a smaller set of African countries during the Clinton and Bush administrations and also found an increase in abortion rates when the policy was enacted in 2001.

“Our latest study strengthened our earlier findings because we were able to look at what happens when the rule was turned off, then on, and then off again,” said Bendavid, referring to the policy’s whipsawing under Clinton, Bush and then Obama.

Miller, who is the director of the King Center and a SIEPR senior fellow, says the team’s research reveals a deeply flawed policy.

“We set out to provide the best and most rigorous evidence on the consequences of this policy,” he said. “What we found is a clear-cut case of government action that everyone on all sides of the abortion debate should agree is not desirable.”

Signs of a Global Pushback

Brooks also notes that their findings may underestimate the rule’s full impact.

“The excess abortions performed due to the policy are more likely to be performed unsafely, potentially harming women beyond pregnancy terminations,” she said.

Under Trump, the international response to U.S. funding cuts has shifted. Norway, Canada and several other countries have pledged to increase funding of international NGOs affected by the policy – though not by enough to cover the expected shortfall, says Miller.

“This shows us,” he said, “that despite the intense partisanship in the U.S. over the rule and its implementation, there are ways that policymakers around the world can offset its effects – by ensuring higher levels of family planning funding, for example.”

Asia Health Policy Program Director Karen Eggleston and colleagues examine China’s progress in enhancing financial protection under its social health insurance to achieve universal health coverage.

In 2009, China launched comprehensive health system reforms to address challenges such as increasing rates of non-communicable diseases and population aging, problems with health financing and healthcare delivery, and overall growing health expectations of its people. Promoting universal health coverage by building a social health insurance system was a central pillar of the reforms.

After a decade of system reforms, has the Chinese government made good on its commitment to bolster universal health coverage? In a new article published in a BMJ collection, a team of four co-authors including Karen Eggleston, APARC’s deputy director and director of the Asia Health Policy Program, evaluates China’s progress towards enhancing financial protection of social health insurance and identifies the main gaps that need to be filled to achieve universal health coverage. Their article is part of a special BMJ collection with Peking University that marks the tenth anniversary of China’s health system reforms by analyzing their accomplishments and challenges ahead.

The 2009 reforms aimed to cover the entire Chinese population with one of three (since 2012 one of two) basic social health schemes. To provide added financial protection to patients with critical illnesses, catastrophic medical insurance was initially launched in 2012 and implemented nationally in 2015. Eggleston and her co-authors determine that the expansion of health insurance has had several major successes. First, it improved access to and use of healthcare. In 2011, China achieved near-universal health insurance coverage, with more than 95% of the Chinese population covered by health insurance. Moreover, the annual inpatient hospital admission rate increased from 3.6% in 2003 to 17.6% in 2017, and admission rates for outpatient services were much higher than the global average.

Second, the expansion of health insurance coverage reduced the share of out-of-pocket heath expenses in total health expenditure, thus raising the level of financial protection. Third, catastrophic medical insurance was also effective in supplementing the basic social health insurance schemes and provided extra financial protection to a range of vulnerable groups. By 2017, more than a billion people in China were covered by such insurance.

However, much remains to be done. Out-of-pocket health expenditures remain fairly high and are one of the main reasons for catastrophic health expenses and low financial protection in China, which disproportionately affect deprived populations. Catastrophic medical insurance currently does not target underprivileged people, while medical aid is relatively small in scale and covers only a minority of patients with catastrophic health expenses.

Eggleston and her colleagues conclude that the Chinese government should focus on underprivileged populations within the current insurance system and enhance their financial protection as an important element of targeted poverty alleviation. Such targeting, the researchers emphasize, requires a clear and integrated policy encompassing the basic social health insurance schemes, catastrophic medical insurance, medical aid, and improved healthcare efficiency.
