CDC collects and reports TBI data to understand:
- How many people are affected by this injury
- Who is most at risk
- The leading ways a person may get a TBI
- Whether programs to prevent TBI are working
Based on the most recent data:
- There were approximately 223,135 TBI-related hospitalizations in 2019* and 69,473 TBI-related deaths in 2021.1
- This represents more than 611 TBI-related hospitalizations and 190 TBI-related deaths per day.
- These estimates do not include the many TBIs that are only treated in the emergency department, primary care, urgent care, or those that go untreated.2
- People age 75 years and older had the highest numbers and rates of TBI-related hospitalizations* and deaths.1 This age group accounts for about 32% of TBI-related hospitalizations and 28% of TBI-related deaths.
- Males were nearly two times more likely to be hospitalized (79.9 age-adjusted rate versus 43.7)* and three times more likely to die1 from a TBI than females (28.3 versus 8.4).
* This rate was calculated using the weighted number of hospitalizations with a primary diagnosis of injury (ICD-10-CM diagnosis codes S00-S99; T07-T34; T36-T50 with a 6th character of 1, 2, 3, or 4; T36.9, T37.9, T39.9, T41.4, T42.7, T43.9, T45.9, T47.9, or T49.9 with a 5th character of 1, 2, 3, or 4; T51-T76; T79; O9A.2-O9A.5; T84.04; or M97) and an ICD-10-CM diagnosis code for an initial medical encounter of TBI (S02.0. S02.1, S02.80-S02.82, S02.91, S04.02, S04.03, S04.04, S06, S07.1, T74.4) in any diagnosis field and dividing it by the corresponding civilian non-institutionalized population per 100,000. Data source: Healthcare Cost and Utilization Project’s National Inpatient Sample. 2019.

Surveillance and research to support data-driven solutions
CDC conducts research on preventing TBIs and reducing the chance for disability and other potential effects of these injuries.
