A solution is for ER doctors to discuss the issue with parents, who might mistakenly think a CT scan is needed if a child bumps his head on the carpet, or that the ER is rationing care by not doing a scan, said Ghurabi.
"Parents are a key component in reducing the unnecessary use of expensive CT scans," he said. "Sit down and explain why you'd rather observe their son than irradiate him with the equivalent of 20 to 30 X-rays."
The study was funded by the U.S. Health Resources and Services Administration/Maternal and Child Health Bureau, Division of Research, Training, and Education, and the Emergency Medical Services of Children Program.
