Many chest X-rays in children are unnecessary

03.12.2014

Researchers at Mayo Clinic found that some children are receiving chest X-rays that may be unnecessary and offer no clinical benefit to the patient, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).

"Chest X-rays can be a valuable exam when ordered for the correct indications," said Ann Packard, M.D., radiologist at the Mayo Clinic in Rochester, Minn. "However, there are several indications where pediatric chest X-rays offer no benefit and likely should not be performed to decrease radiation dose and cost."

Dr. Packard and co-author, Kristen B. Thomas, M.D., head of the pediatric division at Mayo Clinic and assistant professor of radiology at Mayo Medical School, reviewed data from 719 pediatric chest X-ray exams ordered between 2008 and 2014 in Mayo Clinic's inpatient, outpatient and emergency room settings. The patients undergoing the exams ranged in age from newborn to 17 years old.

Of the 719 X-ray exams, 377 exams were ordered for chest pain, 98 indicated syncope (fainting) or presyncope, 21 indicated spells (a general feeling of being unwell or under distress), 37 indicated postural orthostatic hypotension (POTS)--a condition in which blood pressure drops suddenly when the individual stands up from sitting or lying down, 185 indicated dizziness, and one exam indicated cyclical vomiting. Eighty-two of the 719 exams were excluded due to congenital or other known heart disease, and other causes.

The researchers found that in approximately 88 percent of the remaining 637 patients, the exam did not alter clinical treatment.

None of the patients who underwent X-rays for indications including syncope, spells, POTS, dizziness or cyclical vomiting had any finding that affected treatment. Thirty-nine of the 330 non-excluded X-rays for chest pain were positive for pneumonia, bronchial inflammation, trauma, or other conditions.

"Approximately 12 percent of the chest X-rays for chest pain were positive and included respiratory symptoms such as cough, fever or trauma," Dr. Packard said. "There were no positive findings in any chest X-ray for syncope, dizziness, spells, cyclical vomiting or POTS for the past five years, even in our tertiary care center with referrals for rare diseases or unusual presentations."

Optimizing radiation exposure and cost effectiveness are important topics in today's healthcare environment, particularly in a pediatric population, Dr. Packard noted.

"This study addresses both of these issues, which is important not only for physicians but also for young patients and their parents," she said. "I would like this research to help guide clinicians and deter them from ordering unnecessary exams which offer no clinical benefit to the patient."

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
