Use of injury severity variables in determining disability and community integration after traumatic brain injury.

BACKGROUND: Long-term outcome is important in managing traumatic brain injury (TBI), an epidemic in the United States. Many injury severity variables have been shown to predict major morbidity and mortality. Less is known about their relationship with specific long-term outcomes. METHODS: Glasgow Coma Scale, Revised Trauma Score, Injury Severity Score, and Trauma and Injury Severity Score, along with other demographic and premorbid values, were obtained for 378 consecutive patients hospitalized after TBI at a Level I trauma center between September 1997 and May 1998. Of this cohort, 120 patients were contacted for 1-year follow-up assessment with the Disability Rating Scale, Community Integration Questionnaire, and employment data. RESULTS: Univariate analyses showed these to be significant single predictors of 1-year outcome. Multivariate analyses revealed that the Revised Trauma Score and Glasgow Coma Scale had significant additive value in predicting injury variables Disability Rating Scale scores when combined with other demographic and premorbid variables studied. Predictive models of 1-year outcome were developed. CONCLUSION: Injury severity variables are significant single outcome predictors and, in combination with premorbid and demographic variables, help predict long-term disability and community integration for individuals hospitalized with TBI.

Intentional traumatic brain injury: epidemiology, risk factors, and associations with injury severity and mortality.

BACKGROUND: Intentional injury is associated with significant morbidity and mortality and has been associated with certain demographic and socioeconomic groups. Less is known about the relationship of intentional traumatic brain injury (TBI) to injury severity, mortality, and demographic and socioeconomic profile. The objective of this study was to delineate demographic and event-related factors associated with intentional TBI and to evaluate the predictive value of intentional TBI on injury severity and mortality. METHODS: Prospective data were obtained for 2,637 adults sustaining TBIs between January 1994 and September 1998. Descriptive, univariate, and multivariate analyses were conducted to determine the predictive value of intentional TBI on injury severity and mortality. RESULTS: Gender, minority status, age, substance abuse, and residence in a zipcode with low average income were associated with intentional TBI. Multivariate analysis found minority status and substance abuse to be predictive of intentional injury after adjusting for other demographic variables studied. Intentional TBI was predictive of mortality and anatomic severity of injury to the head. Penetrating intentional TBI was predictive of injury severity with all injury severity markers studied. CONCLUSION: Many demographic variables are risk factors for intentional TBI, and such injury is a risk factor for both injury severity and mortality. Future studies are needed to definitively link intentional TBI to disability and functional outcome.

Panic disorder in a patient with traumatic brain injury: a case report and discussion.

Individuals that may be especially susceptible to panic attacks in the rehabilitation setting are patients who have suffered traumatic brain injuries, post-concussion syndrome, lesions, or encephalopathy. An individual is described who suffered a traumatic brain injury and was determined to have suffered a panic attack during his rehabilitation stay. The manifestations of panic attacks are described, using the case report as an example. The psychological aetiology of panic disorders is also reviewed, and treatment options using four major classes of neuropharmacologic agents: benzodiazepines, tricyclic antidepressants, monoamide oxidase inhibitors, and serotonin reuptake inhibitors, are discussed. Given the increasing incidence and survival of patients with traumatic brain injuries, the complications of panic attacks and disorders will become more important; they are a serious condition that can affect an individual's lifestyle, employment, and relationships, and increase the risk of suicide. Rehabilitation specialists should be aware of the manifestations and management of panic attacks and come to appreciate that recognition of this treatable condition is important during all stages of rehabilitation.

Pulmonary complications in traumatic brain injury.

Survivors of traumatic brain injury frequently develop respiratory complications that require specialized knowledge and management skills in both acute and postacute environments. This article discusses the pathophysiology of and treatment options for ventilatory failure, neurogenic pulmonary edema, and aspiration. Management of tracheostomies is also discussed, with particular attention paid to decision making regarding the removal of a tracheal appliance. Long-term tracheal complications are also outlined.
