Using temporary nurses doesn’t mitigate deaths linked with staff shortages

2024-08-19
(Press-News.org) A new study led by the University of Southampton has found that using temporary nursing staff to fill rotas only partially combats an increased risk of patient death associated with staff shortages.

Researchers found that avoiding low nurse staffing levels lowers the risk of death among patients – particularly even when drafting in temporary registered nurses to maintain staffing levels. However, despite this, the risk of death remains elevated compared to when the ward is fully staffed by permanent nurses.

Findings from the study, funded by the National Institute for Health and Care Research (NIHR) and the NIHR Applied Research Collaboration (Wessex), are due to be published in the journal JAMA Network Open.

The research team conducted an observational study on 185 wards across four acute hospital trusts in England between 2015 and 2020 – amounting to a total of over 600, 000 patient admissions. The anonymised participants were adults with an overnight stay, and nursing staff on inpatient wards.

The study found that for each day of low staffing among registered nurses, the risk of patient death increased by 7.9 percent from the norm. The figure for nursing support staff was similar at 7.2 percent. However, this risk was partly, although not completely, mitigated by bringing in temporary staff.

Increasing temporary registered nurses on wards by 10 percent was associated with an increased risk of death of 2.3 percent – with no difference between using agency or hospital bank staff. The figure for nursing support staff saw an increased risk of death of 4 percent and agency staff from this group had a larger adverse impact than bank staff.

Commenting on the study, lead author Professor Peter Griffiths of the University of Southampton said: “Our study shows that addressing low staffing levels by using temporary staff to fill gaps is definitely beneficial in avoiding deaths on wards. The harm associated with low staffing is greater than using temporary staff to rectify shortfalls. However, our findings challenge the assumption that temporary staff are a cost-effective long-term solution to maintaining patient safety.”

The research also showed some evidence that having more senior staff on shift, within both registered nurses and nurse support roles, had some benefit, although there was some inconsistency within these results.

“Previous studies have supported a beneficial effect from using more senior staff within a team and our findings are consistent with this. This suggests the relatively new registered nurse associate role, which will increase the proportion of senior support staff on wards, does have some benefits,” comments Professor Griffiths.

The researchers, who partnered with Portsmouth Hospitals University NHS Trust for the study, acknowledge that further work is needed to understand the role of temporary staff more fully and the effects of different staff mixes on other patient outcomes and quality of care.

AI model aids early detection of autism

AI model aids early detection of autism
2024-08-19
A new machine learning model can predict autism in young children from relatively limited information. This is shown in a new study from Karolinska Institutet published in JAMA Network Open. The model can facilitate early detection of autism, which is important to provide the right support. “With an accuracy of almost 80 percent for children under the age of two, we hope that this will be a valuable tool for healthcare,” says Kristiina Tammimies, Associate Professor at KIND, the Department of Women's and Children's Health, Karolinska Institutet and last author of the study. The research team used a large US database (SPARK) ...

2024-08-19
More than half of women globally experience bacterial vaginosis (BV) — an imbalance of naturally occurring microbes in the female genital tract — at least once in their life. The condition can cause painful symptoms and vaginal discharge, and although treatable with antibiotics, it frequently comes back within a short time. If left untreated, BV can lead to problems with pregnancy and an increased risk of sexually transmitted infections, including HIV. A team of researchers at the Broad Institute of MIT and Harvard; the Ragon Institute of Mass General ...

Outcomes of mitral valve surgery in atrial functional mitral regurgitation

Outcomes of mitral valve surgery in atrial functional mitral regurgitation
2024-08-19
Mitral regurgitation (MR) is a serious heart condition that often requires corrective surgery. It is characterized by the backflow or "regurgitation" of blood from the heart's left ventricle into the left atrium. Atrial Functional Mitral Regurgitation (AFMR), characterized by normal mitral valve (MV) function and left ventricular function but with atrial dilation and defects in the ring-like structure that supports the MV leaflets (mitral annulus), poses diagnostic and therapeutic challenges due to its distinct pathophysiological mechanisms. Historically, studies on AFMR have been limited by small ...

Searching old stem cells that stay young forever

Searching old stem cells that stay young forever
2024-08-19
The sea anemone Nematostella vectensis is potentially immortal. Using molecular genetic methods, developmental biologists led by Ulrich Technau from the University of Vienna have now identified possible candidates for multipotent stem cells in the sea anemone for the first time. These stem cells are regulated by evolutionary highly conserved genes, which in humans are usually only active in the formation of egg and sperm cells, but give ancient animal phyla such as cnidarians a high degree of regenerative capacity to even escape ageing. The results are currently being published in Science Advances and could also provide insights into the human ...

Low cortisol, hair-trigger stress response in the brain may underlie Long COVID

2024-08-19
Proteins left behind by COVID-19 long after initial infection can cause cortisol levels in the brain to plummet, inflame the nervous system and prime its immune cells to hyper-react when another stressor arises, according to new animal research by University of Colorado Boulder scientists. The study, published in the journal Brain Behavior and Immunity, sheds new light on what might underly the neurological symptoms of Long COVID, an intractable syndrome which impacts as many as 35% of those infected with the ...
