Bridges and roads as important to your health as what’s in your medicine cabinet

Improving infrastructure — bridges, highways and water systems, for example — also improves health care, according to UB faculty member Korydon Smith.

Two seemingly unrelated national policy debates are afoot, and we can’t adequately address one unless we address the other.

Health care reform has been the hottest topic. What to do about America’s aging infrastructure has been less animated but may be more pressing.

Yet even as cracks in America’s health system and infrastructure expand, political divides between parties and within parties have stalled efforts to develop policies and implement solutions. Problematically, debates over health care reform and infrastructure projects remain separate.

As a professor of architecture who also studies health equity — the establishment of systems, laws and environments that promote fair access to health care — I believe we have reason to be concerned.

What if a solution to bridging both the political and sectoral divides between health care and infrastructure was, literally, a bridge? Sure, bridges are core elements of infrastructure, but what do bridges have to do with health care?

As it turns out, a lot.

Abroad, substandard infrastructure kills

We have seen the negative effects of poor infrastructure most in poverty-stricken countries.

In October 2016, Haiti saw the importance of bridges. Still reeling from the devastating 2010 earthquakes, the poorest country in the Americas was struck by Hurricane Matthew.

Torrential rains led to contaminated food and water supplies, and, subsequently, a cholera outbreak. They also washed out the bridge over the River La Digue. The collapse broke a link in the primary highway connecting the capital of Port-au-Prince to the southern peninsula of Haiti, the area worst hit by Matthew.

Without road access, medical supplies, water and food rations, community-education programs, and equipment to repair water and sanitation systems could not be delivered. Disease spread further.

Disasters are not the only situations where fractures in infrastructure impact health.

In Uganda — a country with a high prevalence of preventable and treatable illnesses, such as respiratory infections — the “last mile” of the supply chain is a matter of life and death. While effective, low-cost treatments exist, the leading causes of childhood mortality include pneumonia, malaria and diarrheal diseases.

As in the U.S., rural children in Uganda are at a greater risk of death than those living in cities. In fact, children living in the rural northeast region of Karamoja die at more than double the rate of children living in the capital region of Kampala. The health literacy of parents is one factor; access to health facilities is another.

Improving infrastructure, improving health

New research from UB reveals something more striking about the role of supply chains: Many preventable deaths are occurring simply because local clinics and kiosks run out of supplies.

“In some districts,” according to Biplab Bhattacharya, a PhD student on the team, “only 50 percent of health facilities have regular supplies of ACTs,” a primary treatment for malaria, “and many were vulnerable to stock-outs between deliveries.”

Li Lin, the lead researcher, also noted that retailers struggle to keep adequate supplies of inexpensive yet lifesaving over-the-counter therapies, like oral rehydration solutions for children with acute diarrhea.

This research comes from a rather unexpected partnership between scholars in industrial and systems engineering who worked with partners in the Clinton Health Access Initiative and the Ministry of Health in Uganda. The work illustrates the value of nontraditional partnerships in identifying problems and finding solutions.

Future public health efforts in Uganda, therefore, may focus not on the development of vaccines or treatments but on infrastructure, such as information management systems, which can predict stock-outs before they happen, and improved roads, which can enable faster delivery of supplies.

U.S. vulnerable, too

While robust technologies shore up America’s supply chains, including the delivery of medications and other health supplies, other areas of infrastructure are not only deteriorating but also do not address imminent, or recurring, public health threats. I fear America is slowly returning to its status in the early 19th century as a developing nation.

In the late 1800s and early 1900s, cities throughout the U.S. eradicated the spread of waterborne diseases, such as typhoid, by investing in water and sanitation improvements.

However, as the Flint water crisis of 2014 illustrated, America’s infrastructure presents one of the greatest threats to the health of Americans. Michael Beach, associate director for healthy water at the Centers for Disease Control and Prevention, stresses that “the U.S. commitment to bring safe water and sanitation to the country” in the 19th and 20th centuries “was a great first step, but we can’t let our guard down; germs adapt.”

Beach adds that outdated infrastructure has contributed to an estimated 240,000 water main breaks each year and, if not upgraded, can “expose users to sewage, pathogens and other contaminants.”

According to the 2017 Infrastructure Report Card, the average U.S. bridge is 43 years old and there are, on average, 188 million trips each day across structurally deficient American bridges. With each passing car and each passing day, these bridges become more life-threatening.

According to the World Bank, approximately 17 percent of the U.S. GDP goes to health care spending, more than any other country. By contrast, spending on transportation infrastructure amounts to less than 0.4 percent of the country’s GDP. Moreover, during the past decade, health spending has grown, while infrastructure spending has constricted despite the need for upgrades.

While political debates often tie public works projects to economic development, and health care policies to human health, infrastructure and health care intersect. Both have economic and health implications. Civic infrastructures — including the seemingly unrelated sectors of energy, transportation and housing — are as important to the health care toolkit as vaccines, hospital beds and surgical units.

For example, over half a million children under the age of five die every year worldwide due to air pollution. Transportation-related smog is one contributor, which is why cities with the best transportation systems often have a lower incidence of respiratory diseases. Investments in transit not only improve convenience and access, but also reduce governments’ and individuals’ burden of treating otherwise preventable diseases.

Of course, infrastructure spending is not immune to political roadblocks. Questions regarding how to resource a plan, which projects to prioritize and how to award contracts present challenges. New approaches to funding might be legislation on improving health infrastructure, like the construction and renovation of rural hospitals, or the development and purchase of medical technologies for specialized urban health centers, or the training of community-based health professionals who can work across sectors.

We might then build outward, ensuring better transportation to these hospitals, stronger paths of communication from major health centers and the integration of neighborhood services across health, education and transportation sectors. We could also shore up rural hospitals, structurally and financially, as, according to the Chartis Center for Rural Health, 80 have closed across the U.S. since 2010. This is despite higher levels of patient satisfaction than their urban counterparts.

Moving the health care debate to a discussion on infrastructure might accomplish two vital needs. It might advance the health care debate by both walking away from the current gridlock and approaching the destination from a fresh perspective. It also might advance public health by making America’s highways, neighborhoods and water systems safer, mediating the risks of health care and bridge collapses.

READER COMMENT

Very well-done Professor Korydon Smith! Perhaps your initiative with this article will spark an interdisciplinary task force dialogue within the academic 'families' within UB, as well as beyond.

 

I would be interested to hear from faculty and students as to what their thoughts are after reading this article by Professor Smith.
