ObjectiveTo determine the extent to which individuals with spinal cord injuries caused by firearms differed from those caused by motor vehicle crash (MVC) in terms of selected preinjury factors, injury characteristics and related treatment, and outcomes at discharge from rehabilitation; and to determine the effect of ethnicity on preinjury factors and outcome.DesignSurvey including interview of former rehabilitation inpatients and medical records review.SettingModel Spinal Cord Injury Care System centered at an urban, public rehabilitation medical center.ParticipantsVolunteer convenience sample of 164 men who were between the ages of 18 and 35 years at the time of injury and who were injured by firearm or MVC between January 1, 1980 and December 31, 1989. Subjects had completed rehabilitation at a rehabilitation center; they were non-Latino White, African-American, or Latino. Subjects were contacted by mail and telephone. The sample was comprised of 26% of the potential participants; however, differential follow-up rates were highly consistent with distribution of primary characteristics within the population of potential candidates.Main Outcome MeasuresThe Functional Independence Measure (FIM) and total and rehabilitation lengths of stay were the outcome measures. Groups and outcomes were also compared in terms of preinjury education, employment, and indicators of antisocial behavior, as well as neurological deficit, associated injuries, and surgical treatment.ResultsThe firearm and MVC groups were different in terms of ethnic distribution. There were no non-Latino Whites in the firearm group and few African-Americans in the MVC group. With the exception of preinjury education, nonparametric and univariate tests showed differences between the firearm and MVC groups in terms of preinjury employment and indicators of antisocial behavior, associated injuries, surgical treatment, neurological deficit, and lengths of stay. Changes in FIM scores, however, were not different between etiologic or ethnic groups. Multiple regression indicated that injury severity accounted for the largest variance in outcomes and that preinjury factors, etiology, and ethnicity did not contribute significantly to the variance in outcome measures.ConclusionsAlthough preinjury factors are associated with ethnicity and minorities have higher proportions of SCI caused by firearms, these factors do not significantly influence rehabilitation outcomes at discharge. The primary factors influencing rehabilitation outcomes are related to the deficits, associated physical injuries, and related treatments common to the causes of the injury.
