Study finds paramedic care delivered on-scene for 10-35 minutes leads to better outcomes


2015-08-25
(Press-News.org) Less than 10 per cent of paediatric patients who suffer a cardiac arrest outside of the hospital survive. There are many factors which can influence survival rates; paramedic care is one of them.

Thanks to the advanced training of paramedics, today, they can spend more time on the scene doing CPR or providing medical care including administering intravenous fluids and medications. However until now, it has not been known if the length of time spent on the scene and onsite medical interventions by paramedics are associated with improved survival for paediatric patients.

In the largest paediatric cardiac arrest study to date, a team of researchers led by The Hospital for Sick Children (SickKids) and Lawson Health Research Institute found that survival was the highest, especially among teens, with 10 to 35 minutes on the scene in the care and under the treatment of paramedics. The study also found that improved survival was associated with intravenous access and fluid administration, whereas advanced airway attempts (endotracheal intubation) and resuscitation drugs were not. The study is published in Resuscitation.

"Our initial hypothesis was that more time spent on the scene doing quality CPR with advanced medical interventions would mean better patient outcomes. We found that there is an optimal time between 10 and 35 minutes, and after 35 minutes, the outcomes do not improve and actually get worse," says Dr. Jamie Hutchison, senior author on the study, Staff Physician and Research Director in Critical Care Medicine at SickKids. "Interestingly, we found that while longer on-scene time (more than 35 minutes) was associated with higher rates of resuscitation, it had lower rates of survival [compared to 10 to 35 minutes on the scene]. This paradox is valuable information for paramedics as they weigh the potential benefits of spending more time on the scene while considering how to achieve the best possible outcome for the patient."

This was an observational study looking at data from the Resuscitation Outcomes Consortium (ROC) cardiac arrest database from 11 North American regions, including Vancouver, Hamilton, Toronto and Ottawa between 2005 and 2012. The team studied 2,244 patients ranging from three days old to 19 years old with non-traumatic out-of-hospital cardiac arrest, and evaluated survival to the time of hospital discharge.

"Our findings show that scene time is significantly associated with survival to hospital discharge, and that only some interventions are associated with survival," says Dr. Janice Tijssen, principal author on the study, Researcher at Lawson and Paediatric Intensivist at Children's Hospital, London Health Sciences Centre. "For example, placement of intravenous or interosseous needles was associated with improved survival, likely because it allowed fluid administration that was also associated with better outcomes. We hope the findings will help inform paramedics as they make decisions on the best way to treat patients."

Adolescents had the highest rate of survival followed by children and then infants. Infants had the shortest scene time, fewest interventions and lowest rate of witnessed events (meaning the cause of the arrest was unknown). It is possible that there may be a large number of infants who had sudden infant death syndrome.

The study also revealed that more than 10 minutes on the scene was associated with more interventions, suggesting that a 'scoop and run' approach of less than 10 minutes does not allow enough time to apply interventions like IV fluids that may benefit the patient. "But the good news is that in the majority of patients (68.7 per cent) had a scene time between 10 and 35 minutes," adds Tijssen.

Toronto Paramedic Services, Deputy Chief of Program Development and Service Quality, Cindy Nicholson says, "The findings of this study as well as those of other recent research confirms that early intervention and care from Paramedics in the prehospital setting makes a significant difference in quality of life and outcomes for our patients. This study's findings are not only exciting for Toronto Paramedic Services but for the profession in general and most importantly for the patients in our community who benefit from our evidence-based care."

INFORMATION:

Quick facts 2,244 patients studied (1017 infants, 594 children, 633 teens) Infants had the lowest average rate of survival over the whole study period (3.7 per cent) compared to children (9.8 per cent) and teens (16.3 per cent) Survival was highest in the 10-35 minutes on scene time group (10.2 per cent) compared to the over 35 minute group (6.9 per cent) and the under 10 minute group (5.3 per cent)

Comprehensive study of genetic risks for inflammatory bowel disease in African-Americans

2015-08-25
Fast Facts: Inflammatory bowel disease (IBD) has been historically underdiagnosed in African-Americans and is increasing in frequency. Several gene variants for IBD in whites are key risk factors in African-Americans. Also important are unique African ancestral variants that cause protection against IBD. In African-Americans, as in whites and Asians, the dominant region for ulcerative colitis genetic risk in is the human leukocyte antigen region, a major determinant of immune regulation. Researchers at the Johns Hopkins University School of Medicine, along ...

Developing a new tool to detect a frequently missed sex chromosome disorder in boys

Developing a new tool to detect a frequently missed sex chromosome disorder in boys
2015-08-25
NEW YORK, NY (August 25, 2015)-- Klinefelter syndrome is the most common disorder of the male sex chromosomes, yet is rarely diagnosed in children. A new assessment tool is being developed by researchers at Columbia University Medical Center (CUMC) to help pediatricians detect the physical traits of the syndrome. The tool could pave the way for early interventions that prevent and treat a range of physical, psychological, social, and cognitive impairments. The study was published in The Journal of Pediatrics. According to lead author Sharron Close, PhD, boys with Klinefelter ...

Batting practice in the genome

2015-08-25
In the biochemical game of genetics, it was thought that the proteins controlling gene regulation in animals were either spectators or players. But in research appearing in the current issue of eLife, Michigan State University researchers found that spectator proteins are actually practicing up for the big game. They discovered that the proteins are biochemically interacting with thousands of regions of the genome to change the structure of chromosomal material, although only few of them actually are able to change gene expression. "The previous thinking was that these ...

NASA finds vegetation essential for limiting city warming effects

NASA finds vegetation essential for limiting city warming effects
2015-08-25
Cities are well known hot spots - literally. The urban heat island effect has long been observed to raise the temperature of big cities by 1 to 3°C (1.8 to 5.4°F), a rise that is due to the presence of asphalt, concrete, buildings, and other so-called impervious surfaces disrupting the natural cooling effect provided by vegetation. According to a new NASA study that makes the first assessment of urbanization impacts for the entire continental United States, the presence of vegetation is an essential factor in limiting urban heating. Impervious surfaces' biggest ...

The greater a country's gender equality in employment, the higher its homicide rate

2015-08-25
The greater a country's gender equality when it comes to employment, the higher the overall homicide rate, according to a Baylor University study of 146 countries. "The finding does not mean that gender equality in employment increases homicide rates, but there is a correspondence," said sociologist Katie Corcoran, Ph.D. "What remains uncertain is the 'why' behind this relationship, although prior research suggests it may be due to threatening male status. "The research findings are significant because they show that gender inequality does not only affect women," she ...

Genetic study finds association between reduced vitamin D and multiple sclerosis risk

2015-08-25
Genetic findings support observational evidence that lower vitamin D levels are associated with increased risk of multiple sclerosis, according to a new research article by Brent Richards, from McGill University, Canada, and colleagues published this week in PLOS Medicine. Multiple sclerosis is a debilitating autoimmune disease that affects the nerves in the brain and spinal cord. There is no known cure for multiple sclerosis and it usually presents between the ages of 20 and 40 years. While some observational evidence suggests there may be a link between lower vitamin ...

One dose or 2? Cholera vaccination strategies

2015-08-25
A new modeling study appearing this week in PLOS Medicine supports consideration of vaccination campaigns using a single dose of cholera vaccine versus campaigns using the recommended two doses given two weeks apart.. Justin Lessler and colleagues, of Johns Hopkins Bloomberg School of Health, Baltimore, Epicentre, Paris and Médecins Sans Frontières, Geneva focus their modelling analyses on comparing the number of lives that could be saved by adopting a single vaccine dose, which could be more rapidly administered to more people than the internationally licensed ...

Less may be more in slowing cholera epidemics

2015-08-25
An oral cholera vaccine that is in short supply could treat more people and save more lives in crisis situations, if one dose were dispensed instead of the recommended two, new Johns Hopkins Bloomberg School of Public Health research suggests. More than 1.5 billion people around the world are at risk for cholera, a severe diarrheal illness caused by bacteria linked to poor water and sanitation. It is a major killer worldwide, causing an estimated two to three million cases and 100,000 deaths each year, primarily in developing nations. A relatively new vaccine -- internationally ...

Adaptive mutation mechanism may explain some forms of antibiotic resistance

2015-08-25
Evolutionary theory says mutations are blind and occur randomly. But in the phenomenon of adaptive mutation, cells can peek under the blindfold, increasing their mutation rate in response to stress. Scientists at Winship Cancer Institute, Emory University have observed that an apparent "back channel" for genetic information called retromutagenesis can encourage adaptive mutation to take place in bacteria. The results are scheduled for publication in PLOS Genetics on Tuesday, August 25. "This mechanism may explain how bacteria develop resistance to some types of antibiotics ...
