 For boys aged 10 to 19, the concussion rate surges to 7.0 cases for
each 1,000 people in the autumn from 2.9 cases per 1,000 in the
summer, according to an analysis of medical claims for members of
Blue Cross and Blue Shield health plans.
Concussion rates for girls in that age group climb to 3.7 cases for
each 1,000 people in the fall from just 1.9 cases per 1,000 in the
summer.
While the study didn’t examine why injuries spike in the fall, it
may have something to do with the type of sports kids play at this
time of year, said Dr. Trent Haywood, chief medical officer for the
Blue Cross Blue Shield Association, Chicago-based federation of 36
independent Blue Cross and Blue Shield companies.
“The fall season does correlate with contact sports, such as
football, soccer and ice hockey, that are more prone for minor
traumatic brain injuries,” Haywood said by email.
“It is important for coaches and parents to realize there is no
current evidence that helmets, head gear or mouth guards decrease
the incidence of concussions,” Haywood added.
To assess trends in concussion rates, researchers examined data from
medical claims on 936,630 insurance plan members who were diagnosed
with concussion from 2010 through 2015. The analysis, published on
the BCBS website, includes a subset of people with commercial
insurance sold by 36 Blue Cross and Blue Shield plans.
Overall, concussion diagnoses rose 43 percent nationwide during the
study period.
This was driven largely by a 71 percent increase in concussions for
patients aged 10 to 19; diagnoses for patients aged 20 to 64
increased 26 percent.
Even though young males get the most concussions, the injury rate
surged more for young females, the analysis also found.
The good news is that these surges in diagnoses may not necessarily
be driven just by an increase in injuries, said Huiyun Xiang,
director of Center for Pediatric Trauma Research, Nationwide
Children’s Hospital in Columbus, Ohio.
“The significant increase was more likely to be caused by greater
awareness among athletes, parents and coaches around the need to
properly diagnose and treat these head injuries,” Xiang, who wasn’t
involved in the study, said by email.
Researchers also looked at what’s known as post-concussion syndrome,
a complex disorder that can include symptoms like dizziness or
headaches and last for weeks or months after an injury.
Across all ages, the percentage of concussion patients diagnosed
with post-concussion syndrome nearly doubled from 7.3 percent to
13.2 percent during the study period.

About 12 percent of younger concussion patients got this diagnosis
in 2015, as did about 16 percent of older patients.
This, too, may be driven by increased awareness among parents and
coaches about when it’s safe for injured athletes to return to
practice and competition.
“The timing of this increase in concussive diagnoses (2010-2015)
corresponds to the implementation of policies that require better
monitoring through medical clearance prior to returning to play,”
Carolyn McCarty, a researcher at the University of Washington and
Seattle Children’s Hospital who wasn’t involved in the study, said
by email.
Concussion rates found in the study add to a growing body of
evidence suggesting that parents, coaches and athletes are doing a
better job of removing athletes from play as soon as a head injury
is suspected, said Anthony Kontos, research director of the sports
medicine concussion program at the University of Pittsburgh Medical
Center.
But even as more athletes are getting diagnosed, not all of them are
getting necessary follow-up treatment, Kontos, who wasn’t involved
in the study, said by email.
“We need to also focus on making sure young athletes receive proper
care following their concussion, so that they can recover fully and
return to their sport in the safest manner possible,” Kontos said.
