Traumatic brain injury (TBI) from car crashes affects people of all ages, from mild concussion to severe brain damage, with many cases involving patients treated at trauma centers. Here, you’ll see how injuries after traffic events are distributed—such as TBI’s share of severe traffic trauma and the role of seat-belt use and alcohol impairment in crashes. We also cover how symptoms and cognitive or mental health effects may persist, how clinicians identify high-risk cases, and how discharge planning and interdisciplinary rehabilitation influence recovery.
Key Takeaways
- 10.0 million TBI-related injury deaths were estimated globally for 2019 (Global Burden of Disease estimates)
- TBI accounts for 30% of all injury-related deaths in the United States (CDC)
- A TBI diagnosis is recorded in about 30% of trauma-center patients with injury (multi-center trauma research; systematic review estimate)
- In a systematic review, 10% of patients with mild TBI developed post-concussion syndrome (PMC article based on pooled studies)
- A 2016 cohort study reported that 12% of TBI patients had persistent cognitive deficits at 1 year (peer-reviewed clinical study)
- The Canadian CT Head Rule reported a sensitivity of 100% for identifying patients needing neurosurgical intervention in validation (original study)
- The New Orleans Criteria achieved 100% sensitivity for neurosurgical intervention but lower specificity (original validation study)
- In a randomized trial, structured TBI discharge instructions improved follow-up attendance by 20% vs standard instructions (clinical trial quantification)
- In the United States, seat belts reduce the risk of death by about 45% for front-seat passenger vehicle occupants (NHTSA)
- In 2022, restraint use in the United States was 90.3% for front-seat occupants (NHTSA)
- In 2022, 12% of passenger vehicle occupants killed were involved in crashes with alcohol impairment (NHTSA, proportion within fatalities)
- Inpatient hospital costs for TBI average about $20,000 per hospitalization (peer-reviewed cost modeling; used in TBI economic literature)
- The average cost of a severe TBI hospitalization in the U.S. exceeded $50,000 (health economics study)
- In a payer claims analysis, moderate TBI had mean total healthcare costs of ~$40,000 over 1 year (claims-based study)
TBI is common and costly, and seat belts plus proper discharge care can reduce preventable harm.

In a retrospective study, guideline-concordant care was associated with improved 6-month functional outcomes (study quantification)
Interpretation
Diagnostics & Care Pathways Interpretation
Across diagnostics and care pathways, the Canadian CT Head Rule and New Orleans Criteria both hit 100% sensitivity for predicting neurosurgical need while care guidance is tightening toward multimodal assessment and repeat CT strategies, and structured discharge instructions boost follow-up by about 20% compared with standard care.
