Study finds racial disparities in COVID-19 deaths in nursing homes

2021-03-08
(Press-News.org) Nursing homes with the largest proportions of non-White residents experience 3.3 times more COVID-19 deaths than do nursing homes with the largest proportions of White residents, according to a new study from the University of Chicago. The paper, published in JAMA Network Open, suggests that these differences are likely due to nursing home size and the level of coronavirus spread in the local community, reinforcing the inseparability of long-term care facilities from society at large when it comes to bringing the COVID-19 pandemic to heel.

Since the start of the pandemic, between 35% and 40% of COVID-19 deaths have been associated with long-term care facilities. Senior author R. Tamara Konetzka, PhD, the Louis Block Professor of Public Health Sciences and the College at UChicago, wanted to bring her 25 years of experience studying nursing homes to ask why these facilities were experiencing such devastation from the coronavirus and if it was possible to predict which nursing homes were at highest risk.

Konetzka and her collaborator, Rebecca Gorges, PhD, a postdoc in the Department of Public Health Sciences, pulled together data sets from national sources, compiling information from over 13,000 nursing homes, to identify predictors of COVID-19 outcomes in nursing homes. The data represented COVID-19 outcomes during the first waves of the pandemic, beginning between January 1 and May 24 and ending September 23, 2020. "Very early on, we saw some striking relationships with the racial composition of a nursing home, where nursing homes serving more Black and brown residents seem to have more COVID cases and deaths," said Dr. Konetzka.

Nursing homes with the highest percentages of non-White residents had more than three times as many COVID-19 cases and deaths than nursing homes with the highest percentages of White residents. More than 60% of nursing homes with the highest percentages of non-White residents reported at least one COVID-19 death, with an average of 5.6 deaths, compared to only 20% of nursing homes with the highest percentages of White residents reporting at least one death, with an average of 1.7 deaths.

"There were theories floating around that maybe Black and brown residents are just sicker or are in low-quality homes, but we wanted to dig beneath these really alarming statistics and analyze why these outcomes were happening," said Konetzka.

To identify why these racial disparities between nursing homes existed, the investigators compared a number of characteristics of nursing homes to their COVID-19 outcomes, including: overall patient health, facility size, chain membership, ownership type, number of nursing hours, coronavirus spread in the local community, and facility star rating. After controlling for these factors, only two explained the difference in COVID-19 outcomes by race: nursing home size, and COVID-19 rates in the surrounding community.

"It's not about the underlying health of the residents or even the quality of the nursing homes by star rating," said Konetzka. "One factor is just the size of these facilities." Nursing homes with higher percentages of non-White residents tend to be larger than nursing homes with higher percentages of White residents. Large facilities are more likely to experience worse coronavirus outbreaks since their sheer size allows more opportunities for an outbreak to be seeded.

"The other important reason why we see these racial differences is the prevalence of the virus in the surrounding community," said Konetzka. "Black and non-White people in general tend to live in neighborhoods that have a high prevalence of the virus and even the staff who work in these facilities are more likely to live in these neighborhoods. It's about location and size, more than anything else."

These findings were not initially obvious to the investigators. At first, it seemed as if the disparities in COVID-19 outcomes might be explained by Black individuals being more likely to reside in lower quality nursing homes and entering these facilities in worse health than their White counterparts. However, neither of these explanations could account for the differences in COVID-19 outcomes, as it seems that the entire system was unprepared to weather the pandemic.

"I think it was surprising to everyone that low quality of nursing home care wasn't at the root of this. In fact, a few years prior to the pandemic, a lot was made of the fact that the majority of nursing homes had regulatory deficiencies in their infection control procedures. But it turns out even being cited by Medicare or Medicaid isn't predictive. The whole sector was just unable to deal with a crisis of this magnitude," said Konetzka.

According to her, the fundamental facts of how the coronavirus transmits and how nursing homes operate led to this system-wide failure. "The coronavirus can be spread asymptomatically and is airborne. Large nursing homes can have several residents per room and staff must go room to room to give care. COVID-19 is a perfect storm where it doesn't matter if a nursing home is high- or low-quality; all patients are at risk."

This research is part of a larger ongoing project by Konetzka to study the effects of COVID-19 on nursing homes. Her early work in the spring led to her testifying before the Senate Special Committee on Aging on why nursing homes were suffering from poor COVID-19 outcomes and how to improve the ability of the facilities to deal with the coronavirus. "This was really rewarding as an academic, because we do rigorous research about fundamental behaviors and this was an opportunity to directly influence policy and make a difference in people's lives," said Konetzka. While she believes that her and others' research has begun to shape the narrative around nursing homes during the pandemic, Konetzka says there is still more to study.

"There's also still a lot to learn about what works in terms of both state policy and federal policy," said Konetzka. "Nursing homes are a grossly underfunded area of our healthcare system, but they are still really connected to the rest of our system."

The paper's finding that the level of community spread accounted for some of the racial disparities underscores how intimately nursing homes are tied to the rest of society. "We can't just dissociate what's happening in nursing homes from the rest of the pandemic. Solving that problem is part of solving the entire pandemic."

Though there will be an end to the COVID-19 pandemic, Konetzka says the underlying issues in long-term care must still be addressed. "Getting old and needing long-term care is in all our futures. Selfishly, we should work towards a system that is safe and effective, and provides a high quality of life for people as they age. But, in the long run, if we want to prevent these nursing home deaths from happening again in the next pandemic, we have to seriously revisit the whole way we approach and fund long-term care."

Complement inhibition reverses mental losses in preclinical traumatic brain injury models

Complement inhibition reverses mental losses in preclinical traumatic brain injury models
2021-03-08
Traumatic brain injury (TBI) is a major cause of disability and a risk factor for early-onset dementia. The injury is characterized by a physical insult followed acutely by complement driven neuroinflammation. Complement, a part of the innate immune system that functions both in the brain and throughout the body, enhances the body's ability to fight pathogens, promote inflammation and clear damaged cells. Complement plays a role in the brain, regardless of infection or injury, as it influences brain development and synapse formation. In TBI, complement- induced inflammation partially determines the outcome in the weeks immediately following injury. However, more research is needed to define a role for the complement system in neurodegeneration ...

Membrane around tumors may be key to preventing metastasis

Membrane around tumors may be key to preventing metastasis
2021-03-08
For cancer cells to metastasize, they must first break free of a tumor's own defenses. Most tumors are sheathed in a protective "basement" membrane -- a thin, pliable film that holds cancer cells in place as they grow and divide. Before spreading to other parts of the body, the cells must breach the basement membrane, a material that itself has been tricky for scientists to characterize. Now MIT engineers have probed the basement membrane of breast cancer tumors and found that the seemingly delicate coating is as tough as plastic wrap, yet surprisingly elastic like a party balloon, able to inflate to twice its original size. But while a balloon becomes much easier to blow up after some initial effort, the team found that a basement membrane becomes stiffer as it expands. ...

Are higher obesity rates in minority groups a product of systemic racism?

2021-03-08
BOSTON - The higher rates of obesity in Black, Indigenous and People of Color (BIPOC) compared with other groups in the United States can be attributed in large part to systemic racism, according to a new perspective article published in the Journal of Internal Medicine. The authors offer a 10-point strategy to study and solve the public health issues responsible for this disparity. "First, it is important to recognize that the interplay of obesity and racism is real. Once persons recognize this, they can begin to appropriately address and treat obesity in BIPOC communities," says co-author Fatima Cody ...

Hypertension disorders of pregnancy increase risk of premature maternal mortality

2021-03-08
Women who experienced hypertensive disorders of pregnancy (HDPs) but did not develop chronic hypertension have a greater risk of premature mortality, specifically cardiovascular disease (CVD)-related deaths, according to a study published in the Journal of the American College of Cardiology (JACC). A separate JACC study examined the cardiovascular health risks associated with pregnancy in obese women with heart disease. HDPs, which occur in approximately 10% of all pregnancies worldwide, are among the most common health issues during pregnancy. There are four types of HDPs: chronic hypertension, gestational hypertension (GHTN), preeclampsia and ...

Why odors trigger powerful memories

2021-03-08
Other senses re-routed during evolution, but not sense of smell Loss of smell linked to depression and poor quality of life Smell research can help treatments for loss in COVID-19 CHICAGO ---Odors evoke powerful memories, an experience enshrined in literature by Marcel Proust and his beloved madeleine. A new Northwestern Medicine paper is the first to identify a neural basis for how the brain enables odors to so powerfully elicit those memories. The paper shows unique connectivity between the hippocampus--the seat of memory in the brain--and olfactory areas in humans. This new research suggests a neurobiological basis for privileged access by olfaction to memory areas in the brain. The study compares connections between primary sensory areas--including ...

Speeding treatment for urinary tract infections in children

Speeding treatment for urinary tract infections in children
2021-03-08
DALLAS - March 8, 2021 - A study led by UT Southwestern and Children's Health researchers defines parameters for the number of white blood cells that must be present in children's urine at different concentrations to suggest a urinary tract infection (UTI). The findings, published recently in Pediatrics, could help speed treatment of this common condition and prevent potentially lifelong complications. UTIs account for up to 7 percent of fevers in children up to 24 months old and are a common driver of hospital emergency room visits. However, says study leader Shahid Nadeem, M.D., assistant professor of pediatrics at UTSW as well as an emergency department physician and pediatric nephrologist at Children's Medical Center Dallas, these bacterial infections ...

Financial pollution in the US health system

2021-03-08
