A comparison of substance abuse and violence in the prediction of long-term rehabilitation outcomes after traumatic brain injury.

OBJECTIVE: To determine the relative contributions of substance abuse history and violent etiology to the prediction of outcomes for individuals who sustained a traumatic brain injury (TBI) requiring inpatient rehabilitation. DESIGN: Longitudinal study of outcomes 1 year postdischarge from rehabilitation. SETTING: Specialized TBI acute rehabilitation unit. PARTICIPANTS: Three hundred fifty-one individuals consecutively admitted for rehabilitation. INTERVENTIONS: Gathered data from patients' medical records (including etiology of injury, initial Glasgow Coma Scale scores, and FIMtrade mark instrument scores at discharge), demographic details, and history of substance abuse; phone and mail survey data from individuals (Satisfaction with Life Scale [SWLS]; Community Integration Questionnaire [CIQ]). MAIN OUTCOME MEASURES: CIQ and SWLS; relative contributions of injury etiology, demographic and injury-related dependent variables, and substance abuse history to predictive model. RESULTS: Almost 80% of persons with injuries from violence-related causes had a history of substance abuse. Substance abuse was found to contribute to the prediction of life satisfacton and productivity, while violent etiology was not a significant contributor to predictive models. CONCLUSION: Substance abuse history proved to be a strong predictor of long-term outcomes, while violent etiology of injury was less influential. The results of this study emphasize the need to include substance abuse history in all studies of outcomes after TBI, and to increase prevention efforts to limit the effects of such a history.

The utility of the Substance Abuse Subtle Screening Inventory-3 for use with individuals with brain injury.

The utility of the Substance Abuse Subtle Screening Inventory (SASSI-3) for the use with individuals with traumatic brain injuries (TBI) was investigated. The SASSI-3 was administered to 78 subjects prior to discharge from inpatient rehabilitation. The SASSI-3 diagnosis of chemical dependency was compared with the diagnosis of staff psychologists. Lower accuracy, sensitivity, and specificity were found in SASSI-3 diagnosis for the subjects with brain injury, as compared to a normative sample of persons with disabilities participating in a vocational rehabilitation programme. When a diagnosis of 'dependence or abuse' was used, accuracy of the SASSI-3 increased. Comparison of diagnosis based on SASSI-3 versus Blood Alcohol Level (BAL) at the time of injury showed comparable accuracy; however, BAL was found to have higher specificity. For dependence or abuse, BAL continued to be more specific than the SASSI-3; however, the SASSI-3 was more sensitive. Based on these findings, a clinical approach to screening using both BAL and the SASSI-3 is discussed.

Life satisfaction after traumatic brain injury.

OBJECTIVE: To investigate correlates of life satisfaction after traumatic brain injury (TBI). DESIGN: Prospective, longitudinal study of patients with TBI studied 1 and 2 years after injury. SETTING: A specialized inpatient TBI rehabilitation unit in a midwestern academic medical center. SUBJECTS: Two hundred eighteen consecutive patients admitted for rehabilitation, at least 14 years of age, with a primary diagnosis of TBI, consented to participate, and interviewed 1 and/or 2 years after injury (112 interviewed both years, 58 at year 1 only, 48 at year 2 only). MAIN OUTCOME MEASURES: Satisfaction With Life Scale. RESULTS: Stepwise multiple regressions accounted for statistically significant, but small, proportions of variance. Not having a preinjury history of substance abuse and having gainful employment at the time of follow-up were associated with higher life satisfaction both 1 and 2 years after injury. Motor independence at rehabilitation discharge was also associated at 1 year. Current social integration and the absence of depressed mood were associated at 2 years. Life satisfaction was relatively stable between years. Change that did occur was associated with marital status and depressed mood 2 years after injury. CONCLUSIONS: Life satisfaction after TBI seems to be related to attaining healthy and productive lifestyles. Future research should investigate other factors that affect life satisfaction to increase prediction and appreciate all influences on subjective well being after TBI.

Role of agitation in prediction of outcomes after traumatic brain injury.

OBJECTIVE: To determine the role of agitation in the prediction of traumatic brain injury rehabilitation outcomes. DESIGN: A longitudinal study of 340 consecutive patients admitted to an acute traumatic brain injury rehabilitation unit was conducted. Outcomes under study included rehabilitation length of stay, discharge destination, functional independence at discharge (FIM instrument), productivity at 1-yr follow-up, and life satisfaction at 1-yr follow-up (Satisfaction with Life Scale). RESULTS: Univariate analyses suggested that the presence of agitation in rehabilitation is predictive of a longer length of stay and decreased functional independence in the cognitive realm at discharge. In addition, individuals who exhibit agitation at any time during rehabilitation are less likely to be discharged to a private residence. However, multivariate analyses indicated that cognitive functioning at admission to rehabilitation (FIM cognitive) mediates the relationship between the presence of agitation and length of rehabilitation, as well as between agitation and FIM cognitive at discharge. Similar results were found when discharge residence was the dependent variable; however, agitation also contributed some unique variance to the prediction. Lower cognitive functioning at admission to rehabilitation was associated with the occurrence of agitation during rehabilitation, longer length of stay, lower cognitive functioning at discharge, and a decreased likelihood that an individual would be discharged to a private residence. CONCLUSIONS: The results of the multivariate analyses support the contention that agitation and cognition are intimately related, with the long-term effects of the former being at least partially driven by the latter. These findings support the importance of systematically monitoring both agitation and cognition when applying interventions to reduce agitation.

Rating scale analysis of the Agitated Behavior Scale.

OBJECTIVE: Evaluate the measurement properties of the Agitated Behavior Scale (ABS) using rating scale analysis. SAMPLES: Sample 1: 900 observations of 100 individuals with traumatic brain injury; Sample 2: 204 observations of 102 persons with dementia; Sample 3: 241 observations of 6 individuals with anoxia. RESULTS: The calibration indicated that the rating scale was used as intended. The hierarchies of item difficulty were similar across samples. Person and item separation values were within the acceptable range for the TBI sample. Generally, the items work well together, however 3 items misfit the measurement model moderately. CONCLUSIONS: Agitation as measured by the ABS is best represented as a unitary construct. Results provide additional support for the reliability and validity of the ABS.

Reliability of the Agitated Behavior Scale.

OBJECTIVE: The objective of this study was to investigate the interrater reliability of the Agitated Behavior Scale. DESIGN: Ratings made by research assistants and nursing staff were compared. PARTICIPANTS AND SETTING: Forty-five persons with brain injury and 23 persons with progressive dementia were studied at an acute rehabilitation unit and a long-term-care facility. RESULTS: Ratings of persons with brain injury by research assistants yielded a correlation coefficient for the Total score of.920. The correlation coefficients for the factors Disinhibition, Aggression, and Lability were.902,.909, and.726, respectively. Lower coefficients were obtained when the ratings of the research assistants and nursing staff were correlated; these ranged from.364 to.604. The ratings by research assistants of long-term-care facility residents yielded coefficients ranging from.860 to.906 for the Total and factor scores. CONCLUSION: This study shows that the Agitated Behavior Scale is a reliable instrument for measuring agitation in persons with traumatic brain injury, as well as with long-term-care facility residents experiencing dementia.

Cerebral aneurysms: analysis of rehabilitation outcomes.

OBJECTIVE: To classify deficits after aneurysmal subarachnoid hemorrhage (SAH) and correlate rehabilitation outcomes with these findings. DESIGN: A retrospective review of medical records. SETTING: Institution-based rehabilitation hospital. PARTICIPANTS: Eighty patients admitted to a rehabilitation facility after aneurysmal SAH. MAIN OUTCOME MEASURES: For each subject, data were collected for time between surgery and admission, total inpatient days, time orientation at discharge, and level of supervision required at discharge. RESULTS: Fifty-five percent of the subjects were women and 45% were men. The average age was 47 years. Sixty percent of the lesions were right-sided and 40% were left-sided. Aneurysms were localized, in decreasing order of frequency, in the anterior communicating artery, middle cerebral artery, posterior communicating artery, internal carotid artery, basilar artery, anterior cerebral artery, and posterior inferior cerebellar artery distribution. CONCLUSION: Longer rehabilitation stays were associated with right-sided lesions (mean = 44.64 versus 33.93 days) and motor impairment (mean = 43.8 versus 31.53 days). A trend suggested that motor impairment also predicted the level of supervision required at discharge. The shorter the time between surgery and admission to rehabilitation, the more likely the patient will be oriented at the time of discharge (29.47 versus 43.29 days).

Systematic bias in outcome studies of persons with traumatic brain injury.

OBJECTIVE: (1) Examine systematic biases created by subjects lost at 1-year follow-up in samples of persons with traumatic brain injury; (2) identify potential threats to generalization of outcomes data. DESIGN: A consecutive sample of admissions to acute rehabilitation studied 1 year following discharge. SETTING: An inpatient brain injury rehabilitation unit in a large, academic medical center. SUBJECTS: Eighty-eight patients with primary diagnosis of traumatic brain injury. MAIN OUTCOME MEASURES: Subjects were considered lost to follow-up when phone calls, mail, clinic visits, and assistance from family failed to allow contact 1 year after discharge from acute rehabilitation. Potential effects of the biased follow-up sample were examined for seven suboptimal outcomes. RESULTS: A total of 38.6% of subjects were lost to follow-up. Subjects intoxicated at time of injury and those with history of substance abuse were more-likely to be lost. Among subjects followed, the likelihood of working or being in school 1 year after discharge was significantly less for those intoxicated at time of injury and those with a history of substance abuse. CONCLUSIONS: Systematic bias in longitudinal studies may result from subjects with substance use problems being lost to follow-up. Population estimates for return to work or school will be overestimated if those lost who have substance use problems resemble those followed.

Factor structure of the Agitated Behavior Scale.

The Agitated Behavior Scale (ABS; Corrigan, 1989) is a 14-item scale developed to monitor agitation during the acute phase of recovery from acquired brain injury. While previous studies have supported the reliability, internal consistency, and concurrent validity of the ABS, the current study was designed to investigate its underlying factor structure, as well as to determine systematic effects of time-of-day on the occurrence of agitation. Subjects were 212 patients with traumatic or other recently acquired brain injury who exhibited agitation during their treatment on a specialized brain-injury unit of an acute rehabilitation hospital. Confirmatory factor analysis revealed that agitation is best represented by one general construct with three underlying factors: Aggression, Disinhibition, and Lability. Analysis of agitation by nursing shift in which ratings were made confirmed that overall level was lowest during the night shift; however, the relationship between time-of-day and underlying factors deviated from this pattern. Results are discussed in terms of the necessity for objective measurement, definition of the construct of agitation, and time-of-day issues in sampling agitated behavior.
