Too Many CT Scans Ordered For Children with Concussions, Says New Study

Researchers from Cincinnati Children’s Hospital Medical Center found that for patients at low risk of bleeding from the brain after a head injury but who have concussion symptoms, pediatricians were more likely to refer to the emergency department and request CTs one day after the injury than in the first few hours after the injury. The study will be presented Oct. 13 at the annual meeting of the American Academy of Pediatrics in San Diego.

“It is generally agreed that if children are one day out from an injury, it is highly unlikely they will need head CT scans, especially in low-risk cases where they have normal physical exams,” says Wendy Pomerantz, MD, an emergency medicine physician at Cincinnati Children’s and the study’s lead author.

Dr. Pomerantz and her colleagues developed an online survey asking pediatricians how they would manage three concussion scenarios. In all scenarios, children were at low-risk of intracranial injury, did not lose consciousness and had normal physical exams. The scenarios involved:

  • A 14-year-old patient who sees a doctor the day of injury with headache, nausea and amnesia.
  • A 9-year-old patient who sees a doctor the day after injury with headache and nausea.
  • A 16-year-old patient who sees a doctor five days after injury with nausea and dizziness.

The researchers found that 14 percent were referred to the emergency department in the first scenario. Forty percent were referred in the second scenario, and 27 percent were referred in the third scenario. In the vast majority of these cases, patients did not need to be referred for emergency care and a CT scan, according to Dr. Pomerantz.

The relatively higher radiation doses associated with CT, compared to most other imaging exams, have raised concerns over an increase in risks associated with radiation exposure. This is particularly true in children, whose organs are more sensitive to the effects of radiation than those of an adult.

“Further professional education about concussion management and limiting CT scans is clearly necessary,” says Dr. Pomerantz.
