Why Are People with Stroke More Likely to Die If Hospitalized on Weekend?

02.11.2010
People admitted to the hospital on a weekend after a stroke are more likely to die compared to people admitted on a weekday, regardless of the severity of the stroke they experience, according to new research published in the November 2, 2010, print issue of Neurology®, the medical journal of the American Academy of Neurology.

“We wanted to test whether the severity of strokes on weekends compared to weekdays would account for lower survival rates on the weekends,” said Moira K. Kapral, MD, of the University of Toronto in Ontario, Canada. Kapral was with the Institute for Clinical Evaluative Sciences in Ontario when the research was done. “Our results suggest that stroke severity is not necessarily the reason for this discrepancy.”

For the study, researchers analyzed five years of data from the Canadian Stroke Network on 20,657 patients with acute stroke from 11 stroke centers in Ontario. Only the first stroke a person experienced was included in the study.

People with moderate to severe stroke were just as likely to be admitted to the hospital on weekends and weekdays, but those with mild stroke were less likely to be admitted on weekends in the study. Those who were seen on weekends were slightly older, more likely to be taken by ambulance and experienced a shorter time from the onset of stroke symptoms to hospital arrival on average.

The study found that seven days after a stroke, people seen on weekends had an 8.1 percent risk of dying compared to a 7.0 percent risk of dying for those seen on weekdays. The results stayed the same regardless of age, gender, stroke severity, other medical conditions and the use of blood clot-busting medications.

“Stroke is not the only condition in which lower survival rates have been linked for people admitted to hospitals on the weekends. The reason for the differences in rates could be due to hospital staffing, limited access to specialists and procedures done outside of regular hours,” said Kapral. “More research needs to be done on why the rates are different so that stroke victims can have the best possible chance of surviving.”

There were no differences found in the quality of stroke care, including brain scans and admission time, between weekends and weekdays.

The study was supported by the Canadian Stroke Network.

The American Academy of Neurology, an association of more than 22,000 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as multiple sclerosis, restless legs syndrome, Alzheimer’s disease, narcolepsy, and stroke.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
