| Blunt Force Trauma versus Firearm Related Brain Injury |
| The Question: What are the functional outcomes for persons with violence related brain injuries from blunt force trauma and from penetrating brain injury? Past Studies have been conducted mainly on military personnel. Recently, several studies have reported on the outcome of civilians with firearm related brain injuries. Studies about the long-term outcomes of persons with firearm related brain injuries are lacking. Studies comparing the outcomes of persons with violence related brain injuries from gunshot wounds versus blunt trauma are scarce. Few studies have looked at specific functional outcomes of violent injury survivors. Prior studies have used the Glasgow Coma Scale as a tool to measure outcome. The Glasgow Coma Scale is limited for such use because it does not posses the precision to measure functional outcome. Using the Glasgow Coma scale, researchers did note a trend towards worse prognosis for injuries caused by blunt trauma. This Study examined 25 persons that had sustained blunt injuries and 25 persons with firearm related brain injuries as the result of a violent act. Their abilities were compared before and after participation in inpatient rehabilitation. Outcome scales believed to be more sensitive than the Glasgow Coma Scale were used, such as the Disability Rating Scale, Rancho Los Amigos Scale, and Functional Independence Measure. The results revealed little difference in outcome between violent injury groups. Who May Be Affected By These Findings: Persons with violence related traumatic brain injury, family members, service providers, funders, and advocates. Caveats: The group studied was small with similar socioeconomic factors. The researchers suspect that the comparable socioeconomic status accounts for much of the similarity in the group’s outcome from inpatient rehabilitation. Larger studies from diverse populations may provide results that are more generalizable. Bottom Line: No significant differences were found between the groups for any of the outcome variables. Although firearm related injuries might have a higher initial death rate, persons who survive to come to rehabilitation appear to have similar outcomes to those persons with non-firearm related brain injuries. Larger trials are needed to better address the concerns of persons with violence related injuries. Find This Study: Zafonte, R. D.; Mann, N. R.; Millis, S. R.; Wood, D. L.; Lee, C. Y.; & Black, K. L.
