Violent traumatic brain injury: occurrence, patient characteristics, and risk factors from the Traumatic Brain Injury Model Systems project.
OBJECTIVE
To examine the occurrence of and characteristics associated with violent traumatic brain injury (TBI) in the Traumatic Brain Injury Model Systems (TBIMS) project for 4 of the 5 original Model Systems centers and to determine the patient characteristics of this group, as well as the risk factors for sustaining such an injury.


METHODS
Prospective evaluation of individuals with violent TBI over a 10-year period.


METHODS
Four TBIMS centers.


METHODS
A total of 1,229 individuals who received acute hospitalization and inpatient rehabilitation care for TBI.


METHODS
Not applicable.


METHODS
The occurrence of a violent TBI.


RESULTS
Twenty-six percent of the participants in the TBIMS project sustained a violent TBI. This type of injury was more common in African-American men who were single and slightly older than the average TBI patient, were unemployed before injury, and had had a previous TBI. A higher injury rate was noted in the earlier part of the evaluation period. Those who sustained a violent TBI had higher levels of caregiver burden and disability, as well as decreased productivity and community reintegration at rehabilitation discharge and at 1 and 2 years postinjury.


CONCLUSIONS
The occurrence of violent TBI in the TBIMS project is consistent with national trends of decreasing incidence of violent injuries in the 1990s. These results present a profile of those who have been injured through violence. The relative risks for sustaining such an injury appear to be well defined when considering demographic and temporal factors.
