For much of the 20th century, medical progress seemed limitless.
Antibiotics revolutionized the care of infections. Vaccines turned deadly childhood diseases into distant memories. Americans lived longer, healthier lives than their parents.
Yet today, some of the greatest success stories in public health are unraveling.
Even as the world struggles to control a mysterious new virus known as COVID-19, U.S. health officials are refighting battles they thought they had won, such as halting measles outbreaks, reducing deaths from heart disease and protecting young people from tobacco. These hard-fought victories are at risk as parents avoid vaccinating children, obesity rates climb and vaping spreads like wildfire among teens.
Things looked promising for American health in 2014 when life expectancy hit 78.9 years. Then, life expectancy declined for three straight years — the longest sustained drop since the Spanish flu of 1918, which killed about 675,000 Americans and 50 million people worldwide, said Dr. Steven Woolf, a professor of family medicine and population health at Virginia Commonwealth University.
Although life expectancy inched up slightly in 2018, it hasn’t yet regained the lost ground, according to the Centers for Disease Control and Prevention.
“These trends show we’re going backward,” said Dr. Sadiya Khan, an assistant professor of cardiology and epidemiology at Northwestern University Feinberg School of Medicine.
Health-Wealth Disparities
To be sure, some aspects of American health are getting better.
Yet the health gap has grown wider in recent years. Life expectancy in some regions of the country grew by four years from 2001 to 2014, while it shrank by two years in others, according to a 2016 study in JAMA.
The gap in life expectancy is strongly linked to income: The richest 1% of American men live 15 years longer than the poorest 1%; the richest women live 10 years longer than the poorest, according to the JAMA study.
“We’re not going to erase that difference by telling people to eat right and exercise,” said Dr. Richard Besser, CEO of the Robert Wood Johnson Foundation and former acting director of the CDC. “Personal choices are part of it. But the choices people make depend on the choices they’re given. For far too many people, their choices are extremely limited.”
The infant mortality rate of black babies is twice as high as that of white newborns, according to the Department of Health and Human Services. Babies born to well-educated, middle-class black mothers are more likely to die before their 1st birthday than babies born to poor white mothers with less than high school education, according to a report from the Brookings Institution.In trying to improve American health, policymakers in recent years have focused largely on expanding access to medical care and encouraging healthy lifestyles. Today, many advocate taking a broader approach, calling for systemic change to lift families out of the poverty that erodes mental and physical health.
“So many of the changes in life expectancy are related to changes in opportunity,” Besser said. “Economic opportunity and health go hand in hand.”
The best-performing counties in the United States have average life expectancies that are now 20 years greater than the lowest-performing counties.
And earned income tax credits — which provide refunds to lower-income people — have been credited with keeping more families and children above the poverty line than any other federal, state or local program, according to the CDC. Among families who receive these tax credits, mothers have better mental health and babies have lower rates of infant mortality and weigh more at birth, a sign of health.
Improving a person’s environment has the potential to help them far more than writing a prescription, said John Auerbach, president, and CEO of the nonprofit Trust for America’s Health.
“If we think we can treat our way out of this, we will never solve the problem,” Auerbach said. “We need to look upstream at the underlying causes of poor health.
It now appears that a major influence on health lies in the Social Determinants of Health
Some hospitals and government programs (such as Medicaid) are allocating funds to improve social determinants of health. Early studies reveal a significant ROI (return of investment).
In Chicago, Advocate Health Care saved nearly $5 million by screening for malnutrition risk factors and establishing an enhanced nutrition care program. In Boston, a six-months-or-longer, home-delivered meals benefit for dual Medicare-Medicaid eligible patients was associated with significant reductions in emergency room visits and overall health care cost savings. An initiative to link WellCare Medicaid and Medicare Advantage plan members to social service organizations resulted in an annual savings of $2,400 per person. In Hennepin County, Minnesota, millions of dollars were saved by offering unconventional services to patients with complex health, housing, and social service needs. The University of Illinois at Chicago reduced costs by 18 percent by identifying homeless patients who could benefit from housing support. These are just a few of the studies and reports documenting the health care system’s efforts to go beyond its own walls to improve health outcomes, decrease the consumption of medical services, and reduce costs.
Most health care professionals have known this for decades. At last, the SDOH is officially recognized, studied and the statistics reveal what actions need to be accomplished. Investments in these determinants will be offset by a significant reduction in direct health costs.
