What is TBI?...

What is Traumatic Brain Injury (TBI)?

According to the CDC, a TBI is caused by a bump, blow, or jolt to the head that disrupts the normal function of the brain. Not all blows or jolts to the head result in a TBI. The severity of a TBI may range from “mild” (i.e., a brief change in mental status or consciousness) to “severe” (i.e., an extended period of unconsciousness or memory loss after the injury).  Most TBIs that occur each year are mild, commonly called concussions.

In 2013,1 about 2.8 million TBI-related emergency department (ED) visits, hospitalizations, and deaths occurred in the United States.

  • TBI contributed to the deaths of nearly 50,000 people.
  • TBI was a diagnosis in more than 282,000 hospitalizations and 2.5 million ED visits.  These consisted of TBI alone or TBI in combination with other injuries.

Over the span of six years (2007–2013), while rates of TBI-related ED visits increased by 47%, hospitalization rates decreased by 2.5% and death rates decreased by 5%.

In 2012, an estimated 329,290 children (age 19 or younger) were treated in U.S. EDs for sports and recreation-related injuries that included a diagnosis of concussion or TBI.3
 

  • From 2001 to 2012, the rate of ED visits for sports and recreation-related injuries with a diagnosis of concussion or TBI, alone or in combination with other injuries, more than doubled among children (age 19 or younger).3

In 2013, 1 falls were the leading cause of TBI. Falls accounted for 47% of all TBI-related ED visits, hospitalizations, and deaths in the United States. Falls disproportionately affect the youngest and oldest age groups:

  • More than half (54%) of TBI-related ED visits, hospitalizations, and deaths among children 0 to 14 years were caused by falls.
  • Nearly 4 in 5 (79%) TBI-related ED visits, hospitalizations, and deaths in adults aged 65 and older were caused by falls.

Being struck by or against an object was the second leading cause of TBI, accounting for about 15% of TBI-related ED visits, hospitalizations, and deaths in the United States in 2013.

  • Over 1 in 5 (22%) TBI-related ED visits, hospitalizations, and deaths in children less than 15 years of age were caused by being struck by or against an object.

Among all age groups, motor vehicle crashes were the third overall leading cause of TBI-related ED visits, hospitalizations, and deaths (14%). When looking at just TBI-related deaths, motor vehicle crashes were the third leading cause (19%) in 2013.

Intentional self-harm was the second leading cause of TBI-related deaths (33%) in 2013.
