Study Finds Big Disparities in Stroke Services Across the U.S.
Low-income communities are up to 42% less likely to obtain stroke center certification.
Hospitals in poor communities are significantly less likely to obtain certification for stroke services, which makes them unable to provide urgent, lifesaving treatment, UC San Francisco researchers are reporting in a 14-year study of the nation’s hospitals.
By contrast, hospitals located in economically mixed or affluent communities were more likely to become stroke certified. Such specialized services are associated with better stroke care and patient outcomes. The findings demonstrate significant disparities across the United States in access to critical neurologic treatment, the researchers said.
The study appeared July 25 in JAMA Network Open.
“Some hospitals do not have the necessary resources to treat patients experiencing certain types of strokes,” said lead investigator Renee Y. Hsia, MD, a UCSF professor of emergency medicine and vice chair for Health Services Research in the Department of Emergency Medicine.
“Our findings can help inform the adoption of broad-based social and policy interventions at the local, state and federal levels to promote equal opportunity and access to important community resources.”
Socioeconomic disadvantage
Stroke center certification, which was introduced in 2004 to improve the quality and coordination of acute stroke care, is granted to acute care hospitals that demonstrate the ability to provide specialized stroke services.
Researchers looked at 5,055 acute, non-federal hospitals from 2009 to 2022. They found that 6% of hospitals were located in the most affluent communities, 11% in relatively advantaged communities, 39% in mixed, 36% in relatively disadvantaged and 7% in the most disadvantaged. Hospital ownership varied: 57% of hospitals were not-for-profit, 17% were for-profit and 22% were government-owned.
After adjusting for population size and hospital capacity, researchers found that hospitals near socioeconomically disadvantaged communities were 20 to 42% less likely to obtain stroke center certification compared with hospitals near communities of average socioeconomic status.
“Hospitals with stroke centers that serve patients with a high proportion of commercial insurance and Medicare tend to be revenue centers, meaning they bring in money for the hospitals,” said Hsia, who is also with the UCSF Philip R. Lee Institute for Health Policy Studies. “Whereas stroke centers in areas with a 'poor' patient payer mix – those with uninsured or Medicaid-insured patients with low reimbursement rates – will operate with much lower or often negative profit margins for those services.
“Providing support for hospitals in disadvantaged communities to obtain stroke center certification may help reduce disparities in stroke care,” she said.

Atomic 'GPS' elucidates movement during ultrafast material transitions
2024-07-26
UPTON, N.Y. — Scientists from the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have created the first-ever atomic movies showing how atoms rearrange locally within a quantum material as it transitions from an insulator to a metal. With the help of these movies, the researchers discovered a new material phase that settles a yearslong scientific debate and could facilitate the design of new transitioning materials with commercial applications.
This research, recently published in Nature Materials, marks a methodological achievement; the researchers demonstrated that a materials characterization technique called atomic pair distribution ...
UMBC scientists work to build “wind-up” sensors
2024-07-26
An international team of scientists, including two researchers who now work in the Center for Advanced Sensor Technology (CAST) at UMBC, has shown that twisted carbon nanotubes can store three times more energy per unit mass than advanced lithium-ion batteries. The finding may advance carbon nanotubes as a promising solution for storing energy in devices that need to be lightweight, compact, and safe, such as medical implants and sensors. The research was published recently in the journal Nature Nanotechnology.
Sanjeev Kumar Ujjain, from CAST, was a lead researcher on the work. He started the project while at Shinshu University, in Nagano, Japan, and continued after arriving ...

New study disputes Hunga Tonga volcano’s role in 2023-24 global warm-up
2024-07-26
New research from a collaborative team featuring Texas A&M University atmospheric scientist Dr. Andrew Dessler is exploring the climate impact of the 2022 Hunga Tonga volcano eruption and challenging existing assumptions about its effects in the process.
The remarkable two-day event, which occurred in mid-January 2022, injected vast amounts of volcanic aerosols and water vapor into the atmosphere. Historically, large volcanic eruptions like Tambora in 1815 and Mt. Pinatubo in 1991 have led to significant cooling effects on the global climate by blocking sunlight with their aerosols. ...
Climate is most important factor in where mammals choose to live, study finds
2024-07-26
While human activity has had a massive effect on the natural world, a new study from North Carolina State University finds that climate is still the most influential factor in determining where mammals can thrive. The work sheds light on how climate change will affect wildlife populations.
Roland Kays, lead author of a paper on the work, said the study’s goal was to compare the importance of climate versus human factors in where mammals chose to live. To do so, researchers collected data on 25 mammal species from 6,645 locations across the United States. The study is one of the largest camera trap data analyses ever done. The data came ...
New study highlights global disparities in activity limitations and assistive device use
2024-07-26
A new study of over 175,000 people in 25 countries revealed that individuals in low- and middle-income countries face greater challenges with daily activities and are less likely to use assistive devices compared to those in high-income countries. These findings raise concerns about the global burden of disability, particularly in low-income countries.
Despite decreases in death and cardiovascular disease rates and increases in life expectancy worldwide, people in low- and middle-income countries still ...
Study finds targeting inflammation may not help reduce liver fibrosis in MAFLD
2024-07-26
Researchers at UCLA Health uncovered new information about the role inflammation plays in mitigating liver fibrosis, which is associated with metabolic-associated fatty liver disease (MAFLD), one of the most common diseases in the world affecting up to 40 percent of U.S. adults. While inflammation in the liver has long been considered a prerequisite to developing liver fibrosis, the scarring and thickening of tissue that can impair the liver’s ability to function, this new research suggests ...
