Disrupted access to healthcare during pandemic linked to avoidable hospital admissions

Findings highlight need for increasing healthcare investment to tackle short and long term implications of covid-19 pandemic

2023-07-20

(Press-News.org) People who experienced disrupted access to healthcare (including appointments and procedures) during the covid-19 pandemic were more likely to have potentially preventable hospital admissions, finds a study published by The BMJ today.

This is the first study to examine the impact of disruption on health outcomes using individual level longitudinal data, and the researchers say reducing the backlog from covid-19 disruption is vital to tackle the short and long term implications of the pandemic.

The covid-19 pandemic created unprecedented disruption to healthcare in the UK. This included disrupted access to appointments (eg. visiting a doctor or an outpatient department) and procedures (eg. surgery, cancer treatment).

Previous research has described the extent of this disruption, but no study has yet examined its potential impact on health outcomes at an individual level.

To fill this knowledge gap, researchers accessed data from seven longitudinal studies in the UK Longitudinal Linkage Collaboration (UK LLC) with linked data for 29,276 people in England to their NHS electronic health records from 1 March 2020 to 25 August 2022.

Their main measure of interest was avoidable emergency hospital admissions.

These were defined as admissions for ambulatory care sensitive conditions (those that can be, in theory, treated through community care) and emergency urgent care sensitive conditions (urgent conditions that suddenly worsen and may result in admissions, but should be treated in the community whenever possible).

A total of 9,742 participants (35%) reported some form of disrupted access to healthcare during the covid-19 pandemic.

After adjusting for other potentially influential factors, the researchers found that, overall, people who reported any form of disruption in accessing healthcare were at increased risk of hospital admission for any (80% higher odds), acute (twofold), and chronic (80%) ambulatory care sensitive conditions.

They then investigated outcomes according to the type of healthcare disruption experienced.

This showed that people who experienced disrupted access to procedures had 77% higher odds of being admitted to hospital for any ambulatory care sensitive condition, 88% higher odds of being admitted for a chronic ambulatory care sensitive condition, 45% higher odds of an emergency urgent care sensitive admission, and 57% higher odds of any hospital admission.

People who experienced disruption in accessing appointments had 52% higher odds of hospital admission for any ambulatory care sensitive condition and 46% higher odds of any hospital admission.

These are observational findings so no firm conclusions about cause and effect can be drawn and the researchers acknowledge that not all avoidable hospital admissions would have been caused by disruption of care. What’s more, they did not have any data on people’s difficulties in accessing healthcare before the pandemic, and because healthcare disruption was self-reported, it might be subject to bias.

However, by combining individual level data from longitudinal studies with electronic health records they were able to provide a more complete and detailed picture of hospital admissions across a national healthcare system during a period of great disruption.

As such, they say: “The external shock to the health system caused by the covid-19 pandemic seriously disrupted access to healthcare and this impact is having negative impacts on hospital admissions that could potentially be preventable.”

These findings “highlight the need to increase healthcare investment to tackle the short and long term implications of the pandemic, and to protect treatments and procedures during future pandemics,” they conclude.

Exposure to antiseizure medications does not harm neurological development in young children

2023-07-20

PITTSBURGH, July 19, 2023 — Most mothers who took prescription antiseizure medications during pregnancy can breathe a sigh of relief: A new study published today in Lancet Neurology found that young children who were exposed to commonly-prescribed medications in utero do not have worse neurodevelopmental outcomes than children of healthy women. Commonly used antiseizure medications such as lamotrigine and levetiracetam are generally considered effective and safe, especially compared to many first-generation epilepsy treatments that carried profound risks to the unborn child. ...

AJR on sociodemographic factors and screening CTC among Medicare beneficiaries

2023-07-20

Leesburg, VA, July 19, 2023—According to an accepted manuscript published in the American Journal of Roentgenology (AJR), lacking Medicare coverage could contribute to greater income-based differences in use of screening CT colonography (CTC) than of other recommended screening strategies or of diagnostic CTC. Noting that Medicare’s non-coverage for screening CTC may account for lower adherence with screening guidelines among lower-income beneficiaries, “Medicare coverage of CTC could reduce income-based disparities for individuals avoiding optical colonoscopy due to invasiveness, need for anesthesia, or complication ...

Study sheds light on cellular interactions that lead to liver transplant survival

2023-07-20

A new study identifies how certain proteins in the immune system interact leading to organ rejection. The study, which involved experiments on mice and human patients, uncovered an important communication pathway between two molecules called CEACAM1 (CC1) and TIM-3, finding that the pathway plays a crucial role in controlling the body's immune response during liver transplantation. When an organ is transplanted from a donor to a recipient, the recipient's immune system recognizes the transplanted tissue as foreign, activating an immune response that can lead to rejection. T cells play a significant role ...

A potential new biomarker for Alzheimer’s

2023-07-20

Alzheimer’s is considered a disease of old age, with most people being diagnosed after 65. But the condition actually begins developing out of sight many years before any symptoms emerge. Tiny proteins, known as amyloid-beta peptides, clump together in the brain to form plaques. These plaques lead to inflammation and eventually cause neuronal cell death. Interplay of proteins in the brain reveals disease mechanism Exactly what triggers these pathological changes is still unclear. “We’re lacking good diagnostic markers that would allow us to reliably detect the disease at an early stage or make predictions about its course,” says Professor ...

SARS-CoV-2 infects liver, stimulating glucose production and contributing to severe form of COVID-19

2023-07-19

Research conducted at the University of São Paulo (USP) in Brazil shows that SARS-CoV-2, the virus that causes COVID-19, can infect liver cells (hepatocytes), stimulating glucose production and leading to a condition similar to diabetes (hyperglycemia) in hospitalized patients, even if their blood sugar level was normal before they were admitted to hospital. An article on the study is published in Proceedings of the National Academy of Sciences (PNAS). The findings describe part of the mechanism used by the virus to infect liver cells and impair glucose metabolism, and point ...

Research could pave way to greener, more sustainable products made with renewable carbon

2023-07-19

Carbon-based materials have several qualities that make them attractive as catalysts for speeding up chemical reactions. They are low-cost, lightweight and their high surface area provides a good scaffold on which to anchor catalysts, keeping them stable and dispersed far apart, while providing molecules a lot of surface area to work. This makes carbons useful for energy storage and sensors. Over the last 10 years, carbons have been used in electrochemistry to catalyze reactions to make chemicals and fuel cells. However, ...

Unlocking the power of molecular crystals: a possible solution to nuclear waste

2023-07-19

In a world increasingly concerned about the environmental and geopolitical implications of fossil fuel usage, nuclear energy has resurfaced as a subject of great interest. Its ability to generate electricity at scale without greenhouse gas emissions holds promise as a sustainable clean energy source that could bridge society’s transition away from fossil fuels to a net-zero future. However, nuclear power generation does produce radioactive waste. The safe management of nuclear waste remains a crucial challenge that must be addressed to gain public confidence in this transformative power solution. Now, a team of University of Houston researchers has come up with an innovative ...
