Functional outcome for African Americans and Hispanics treated at a traumatic brain injury model systems centre

Objective: To describe the demographics, incidence and functional outcome for African Americans and Hispanics treated at a traumatic brain injury (TBI) model systems centre. Design: Retrospective data analysis of patients admitted to an acute inpatient rehabilitation national TBI model systems centre. Setting: A tertiary care university medical centre participating in the NIDRR Traumatic Brain Injury Model Systems project. Subjects: Eighty-seven patients with TBI admitted to a Model Systems acute intensive interdisciplinary rehabilitation setting between 1989-1999. Information was extracted from the National TBI Model Systems data base for demographics such as age, race, education, gender, marital and employment status, sponsorship, injury aetiology and severity. Outcome measures: Functional outcome was determined using the Functional Independence Measure (FIM), and the Disability Rating Scale (DRS) at the time of admission and discharge. Results: Descriptive statistics were completed using SPSS. African American (94.3%) and Hispanic (5.7%) patients were injured most often as a result of motor vehicle accidents (48.8%). Males comprised 86.2% of this population, which had an average age of 34.5 years (SD = 13.1). On admission, average GCS score was 7.8 (SD = 3.6), average DRS was 13.5 (SD = 5.8), and average FIM total score was 49.8 (SD = 26.5). Average length of unconsciousness was 5.2 days (SD = 27.9), while average length of post-traumatic amnesia was 41.9 days (SD = 59.3). At the time of injury, 78.2% of the patients were not married. The majority of patients (97.7%) had private residences and 88.5% returned to their original home. Most patients had at least a high school education or passed a high school equivalent exam (49.4%) and were employed (70.1%) at the time of injury. Only 7% of the patients had a history of prior TBI. With regard to substance use, only 34.2% of patients reported pre-morbid illicit drug use. However, 50.5% met criteria for heavy or moderate alcohol use rates. Only 35.6% of patients reported a pre-morbid history of arrests, with the average number of arrests equal to 4.5 (SD = 10.2). Within this population, the number of drug or alcohol related arrests was 4.8 (SD = 13.5). Conclusions: Unmarried African American males, with an average age of 35 years, predominated at this institution. The primary mechanism of injury was motor vehicle accidents. The majority of patients had, at least, a high school education or passed an equivalency exam, were employed at the time of their injury and were discharged to their prior private residence. While half of the patients met criteria for moderate-to-heavy alcohol consumption, only one-third of the patients reported a history of premorbid illicit drug use. This descriptive analysis supports the need for further investigation of minority populations that sustain TBI and will enhance the accuracy of implications that minority status may have on functional outcome.OBJECTIVE To describe the demographics, incidence and functional outcome for African Americans and Hispanics treated at a traumatic brain injury (TBI) model systems centre.

Cultural competence in the multidisciplinary rehabilitation setting: are we falling short of meeting needs?

We present issues relevant to rehabilitation providers who wish to develop or improve their cultural competence in their medical setting and interdisciplinary team. Two case scenarios are presented that illustrate the complexities introduced into the medical rehabilitation setting by the increased numbers of minority patients in the United States in the last 20 years. Professional codes of conduct and practice are discussed for 3 rehabilitation disciplines: physiatry, rehabilitation psychology and neuropsychology, and nursing. The current status of and improvements in professional and continuing medical education are then outlined. Challenges faced by rehabilitation providers seeking to become more culturally competent in their practices are related in the following topic areas: (1) continuing education in language and cultural issues, (2) assessment instruments appropriate for diverse patient populations, (3) majority versus minority population values and beliefs, (4) impact of the immigration and acculturation experiences, (5) health care and insurance coverage issues, (6) attitudes and beliefs about disability, and (7) past experiences with medical professionals and systems. Suggestions for developing and applying enhanced cultural awareness in clinical rehabilitation practice are provided.

Use of Antiepileptics in Traumatic Brain Injury: A Review for Psychiatrists

In recent years, the number of new antiepileptic agents has been growing, as have the potential applications. Traumatic brain injury (TBI) patients often present with behavioral disturbances that may be amenable to treatment with antiepileptic drugs. These conditions include bipolar disorder, as well as posttraumatic seizures and agitation. We review treatment of these three conditions with newer agents, as well as past literature on treatment with older antiepileptic drugs. We also review the pharmacology of newer antiepileptic drugs and summarize reports that indicate possible utility in the TBI population. Although there is a paucity of evidence for brain injury patients specifically, experience with similar groups suggests that these drugs may be useful. Further trials are indicated to clarify the role of the new antiepileptic agents, which may offer more tolerable side effect profiles than do current treatments.
