Psychosocial outcome in patients with moderate to severe head injury: 2-year follow-up

Predictors and Functional Outcomes Associated With Longitudinal Trajectories of Anxiety and Depression from 2 to ≥36 Months After Moderate to Severe Traumatic Brain Injury

This study investigated longitudinal trajectories of anxiety and depressive symptoms following moderate-severe traumatic brain injury (TBI), predictors of the trajectories, and associations with 1-year return to productivity. One hundred forty-eight patients with moderate-severe TBI were assessed at 2, 5, 12, and ≥36 months post-injury on the Beck Anxiety Inventory and the Beck Depression Inventory. Clinical interviews obtained information about demographics, injury characteristics, and 1-year return to productivity. Latent growth mixture modeling identified trajectories of anxiety and depression across time. The three-step method identified predictors of trajectories, and χ2 analyses determined associations between trajectories and 1-year return to productivity. Analyses revealed that four-class models of anxiety and depression best fit the data. Most individuals had stable minimal (67%) or low (18%) levels of anxiety over time. Two other subsets of individuals were classified by anxiety that worsened rapidly (7%) or improved in the 1st year but worsened by 3 years post-injury (9%). Similarly for the depression trajectories, most individuals had stable minimal (70%) or low (10%) levels of depression over time. Others had depression that worsened rapidly (12%) or was delayed, with onset 1-year post-injury (8%). Predictors of worsening anxiety and depression included younger age, less education, and male gender. Those with worsening anxiety or depression were less likely to return to productivity by 1-year post-injury. There is a significant burden of anxiety (15%) and depression (20%) in the 3 years after moderate-severe TBI. Future research targeting at-risk patients may help to improve quality of life and functional recovery.

Chronic motor performance following different traumatic brain injury severity-A systematic review

Introduction

Traumatic brain injury (TBI) is now known to be a chronic disease, causing ongoing neurodegeneration and linked to increased risk of neurodegenerative motor diseases, such as Parkinson's disease and amyotrophic lateral sclerosis. While the presentation of motor deficits acutely following traumatic brain injury is well-documented, however, less is known about how these evolve in the long-term post-injury, or how the initial severity of injury affects these outcomes. The purpose of this review, therefore, was to examine objective assessment of chronic motor impairment across the spectrum of TBI in both preclinical and clinical models.

Methods

PubMed, Embase, Scopus, and PsycINFO databases were searched with a search strategy containing key search terms for TBI and motor function. Original research articles reporting chronic motor outcomes with a clearly defined TBI severity (mild, repeated mild, moderate, moderate-severe, and severe) in an adult population were included.

Results

A total of 97 studies met the inclusion criteria, incorporating 62 preclinical and 35 clinical studies. Motor domains examined included neuroscore, gait, fine-motor, balance, and locomotion for preclinical studies and neuroscore, fine-motor, posture, and gait for clinical studies. There was little consensus among the articles presented, with extensive differences both in assessment methodology of the tests and parameters reported. In general, an effect of severity was seen, with more severe injury leading to persistent motor deficits, although subtle fine motor deficits were also seen clinically following repeated injury. Only six clinical studies investigated motor outcomes beyond 10 years post-injury and two preclinical studies to 18-24 months post-injury, and, as such, the interaction between a previous TBI and aging on motor performance is yet to be comprehensively examined.

Conclusion

Further research is required to establish standardized motor assessment procedures to fully characterize chronic motor impairment across the spectrum of TBI with comprehensive outcomes and consistent protocols. Longitudinal studies investigating the same cohort over time are also a key for understanding the interaction between TBI and aging. This is particularly critical, given the risk of neurodegenerative motor disease development following TBI.

Exploring the measurement of pediatric cognitive-communication disorders in traumatic brain injury research: A scoping review

OBJECTIVE

To synthesize information about the constructs measured, measurement instruments used, and the timing of assessment of cognitive-communication disorders (CCDs) in pediatric traumatic brain injury (TBI) research.

METHODS AND PROCEDURES

Scoping review conducted in alignment with Arksey and O'Malley's five-stage methodological framework and reported per the PRISMA extension for Scoping Reviews. Inclusion criteria: (a) cohort description, case-control, and treatment studies; (b) participants with TBI aged 5-18 years; (c) communication or psychosocial outcomes; and (d) English full-text journal articles. The first author reviewed all titles, abstracts, and full-text articles; 10% were independently reviewed.

OUTCOMES AND RESULTS

Following screening, a total of 687 articles were included and 919 measurement instruments, measuring 2134 unique constructs, were extracted. The Child Behavior Checklist was the most used measurement instrument and 'Global Outcomes/Recovery' was the construct most frequently measured. The length of longitudinal monitoring ranged between ≤3 months and 16 years.

CONCLUSIONS AND IMPLICATIONS

We found considerable heterogeneity in the constructs measured, the measurement instruments used, and the timing of CCD assessment in pediatric TBI research. A consistent approach to measurement may support clinical decision-making and the efficient use of data beyond individual studies in systematic reviews and meta-analyses.

Self-reported outcomes and patterns of service engagement after an acquired brain injury: a long-term follow-up study

PRIMARY OBJECTIVE

To describe the clinical characteristics, self-reported outcomes in domains relating to activities of daily living and patterns of service engagement in the survivors of a moderate-to-severe acquired brain injury over seven years.

RESEARCH DESIGN

A longitudinal research design was used.

METHODS AND PROCEDURES

Thirty-two individuals who sustained a moderate-to-severe acquired brain injury completed a Sociodemographic and Support Questionnaire at one (t1) and seven years (t2) after completing a publicly funded inpatient neurorehabilitation program.

MAIN OUTCOMES AND RESULTS

There were minimal changes in independent living, mobility, ability to maintain key relationships and in return to work in the interval between t1 and t2. Sixty-nine percent of participants engaged with two or more allied health professional services and 75% engaged with support services in the community over the seven years.

CONCLUSIONS

There were minimal additional gains in outcomes relating to activities of daily-living and there was a high level of service need in the first decade postinjury. Young and middle-aged individuals who sustain an ABI may continue to live in the community for decades with some level of disability and may require ongoing access to services.

Epidemiology of Chronic Effects of Traumatic Brain Injury

Although many patients diagnosed with traumatic brain injury (TBI), particularly mild TBI, recover from their symptoms within a few weeks, a small but meaningful subset experience symptoms that persist for months or years after injury and significantly impact quality of life for the person and their family. Factors associated with an increased likelihood of negative TBI outcomes include not only characteristics of the injury and injury mechanism, but also the person’s age, pre-injury status, comorbid conditions, environment, and propensity for resilience. In this article, as part of the Brain Trauma Blueprint: TBI State of the Science framework, we examine the epidemiology of long-term outcomes of TBI, including incidence, prevalence, and risk factors. We identify the need for increased longitudinal, global, standardized, and validated assessments on incidence, recovery, and treatments, as well as standardized assessments of the influence of genetics, race, ethnicity, sex, and environment on TBI outcomes. By identifying how epidemiological factors contribute to TBI outcomes in different groups of persons and potentially impact differential disease progression, we can guide investigators and clinicians toward more-precise patient diagnosis, along with tailored management, and improve clinical trial designs, data evaluation, and patient selection criteria.

The timeframe for safe resumption of high-level mobility following traumatic brain injury is currently unknown: a systematic review

PURPOSE

To examine the safety of high-level mobility (HLM) prescription in the early sub-acute phase of recovery following moderate-to-extremely severe traumatic brain injury (TBI) with specific focus on provocation of concussion-like symptoms.

DESIGN

Systematic review. PROSPERO ID: CRD42017069369.

MAIN MEASURES

Extracted data included study design, brain injury severity, time to commence HLM, type of HLM, physiological and symptom monitoring, and rate of adverse events.

RESULTS

Nineteen studies were included in the review. Fifteen studies included participants who commenced HLM within 6 weeks of injury, with the earliest time to commencement being 3 days. Overall, adverse events and symptom monitoring were poorly reported. A total of six adverse events were reported across three studies. One of the six adverse events was a concussion-like symptom. No falls were reported. No studies monitored concussion-like symptom provocation in direct relation to HLM.

CONCLUSION

A safe timeframe for return to HLM after moderate-to-extremely severe TBI could not be determined due to insufficient reporting of symptom monitoring and adverse events. Further research into the safety of HLM in the early sub-acute rehabilitative stage after moderate-to-extremely severe TBI is required in order to better understand potential sequelae in this population.IMPLICATIONS FOR REHABILITATIONHigh-level mobility assessment and training is commonly reported in the early sub-acute phase of recovery following moderate-to-extremely severe traumatic brain injury.There is no consensus on a safe timeframe to commence high-level mobility assessment or training after moderate-to-extremely severe traumatic brain injury.High-level mobility assessment and training appears to be safe in the early sub-acute phase following moderate-to-extremely severe traumatic brain injury, however, adverse events and symptoms are poorly reported.Clinicians should continue to proceed with caution when assessing and prescribing high-level mobility for patients with moderate-to-extremely severe traumatic brain injury in the early sub-acute phase of recovery and monitor for risks such as falls and exacerbation of concussion-like symptoms.

Models of brain injury vocational rehabilitation: The evidence for resource facilitation from efficacy to effectiveness

BACKGROUND:

Resource Facilitation (RF) is an intervention developed to improve return to work (RTW) following brain injury. RF is an individualized treatment specializing in connecting patients and caregivers with community-based resources and services to mitigate barriers to return to work.

OBJECTIVES:

Examine the effectiveness of the RHI RF program for a clinical prospective cohort of participants referred to this program from the State Vocational Rehabilitation agency.

METHODS:

Participants were 243 participants with data drawn from the two sources: 33 from previous randomized controlled trial (RCT) control groups who did not receive RF and 210 from clinical patients discharged from the RHI RF program.

RESULTS:

At discharge from RF, a greater proportion of the treatment group obtained employment than the control group [X² ₍₁₎  = 5.39, p = 0.018]. When controlling for baseline level of disability, treatment group significantly predicted employment outcome (Wald = 4.52, p = 0.033) and participants in the treatment group were 2.3 times more likely to return to work than controls.

CONCLUSIONS:

Previous RCTs have studied the RHI RF model and demonstrated significant efficacy. The findings from the present study are consistent with the employment rates found in the previous RCT’s following RF, and also provide initial support for the clinical effectiveness of RF.

Methodological Issues in Qualitative Research for the Researcher/Practitioner

This paper examines some of the methodological and ethical issues that arose during the course of a qualitative study, which aimed to gain an understanding of the experience of head injury and the impact of rehabilitation. It focuses particularly on the problems that may be relevant for clinicians and researchers investigating aspects of their practice. The questions of the relationships between the researcher and the respondents, reflexivity and the dynamics of power during data collection and data analysis are discussed. These could be important considerations for others who wish to conduct research in their practice setting.

White Matter Microstructural Compromise Is Associated With Cognition But Not Posttraumatic Stress Disorder Symptoms in Military Veterans With Traumatic Brain Injury

OBJECTIVE

To investigate white matter microstructure compromise in Veterans with a history of traumatic brain injury (TBI) and its possible contribution to posttraumatic stress disorder (PTSD) symptomatology and neuropsychological functioning via diffusion tensor imaging.

PARTICIPANTS AND METHODS

Thirty-eight Veterans with mild (n = 33) and moderate (n = 5) TBI and 17 military control participants without TBI completed neuropsychological testing and psychiatric screening and underwent magnetic resonance imaging an average of 4 years following their TBI event(s). Fractional anisotropy (FA) and diffusivity measures were extracted from 9 white matter tracts.

RESULTS

Compared with military control participants, TBI participants reported higher levels of PTSD symptoms and performed worse on measures of memory and psychomotor-processing speed. Traumatic brain injury was associated with lower FA in the genu of the corpus callosum and left cingulum bundle. Fractional anisotropy negatively correlated with processing speed and/or executive functions in 7 of the 8 tracts. Regional FA did not correlate with memory or PTSD symptom ratings.

CONCLUSION

Results suggest that current PTSD symptoms are independent of TBI-related white matter alterations, as measured by diffusion tensor imaging. In addition, white matter microstructural compromise may contribute to reduced processing speed in our sample of participants with history of neurotrauma. Findings of the current study add insight into the factors associated with complicated recovery from mild to moderate TBI.

Comparison of long-term outcomes following traumatic injury: what is the unique experience for those with brain injury compared with orthopaedic injury?

OBJECTIVE

Whilst it has been well-demonstrated that traumatic brain injury (TBI) results in long-term cognitive, behavioural and emotional difficulties, less is understood about how these outcomes differ from those following traumatic orthopaedic injury (TOI). The aim of this study was to compare self-reported outcomes at 5-10 years post-injury for those with TBI, TOI, and uninjured controls. It was hypothesised that participants with TBI would have greater cognitive difficulties; participants with TOI and TBI would have similar functional and physical outcomes, both being poorer than controls; and participants with TBI would have poorer psychosocial outcomes than those with TOI.

PARTICIPANTS AND METHODS

Eighty-eight individuals with complicated mild to severe TBI and 96 with TOI recruited during inpatient rehabilitation were followed up 5-10 years post-injury, together with 48 controls followed over a similar period. Self-report measures of global functioning (GOS-E), quality of life (SF-36), psychological wellbeing (SCL-90-R, HADS, PCL-S), psychosocial difficulties (SIP), cognitive difficulties (SF-36 COG), pain (BPI), and fatigue (FSS) were administered.

RESULTS

Outcomes for individuals with TBI and TOI differed significantly from controls, with poorer global functioning, and greater psychological distress and interference from pain. Only participants with TBI reported greater cognitive difficulties and anxiety than controls, and were less likely to be employed or in a relationship. Participants with TBI reported greater anxiety, PTSD, psychological distress and psychosocial difficulties than those with TOI.

CONCLUSIONS

Both TOI and TBI cause long-term disability, interference from pain, and psychological distress. However, cognitive impairments, unemployment, lack of long-term relationships, anxiety and PTSD are more substantial long-term problems following TBI. Findings from this study have implications for managing risks associated with these injury groups and tailoring rehabilitation to improve long-term outcomes.

Longitudinal follow-up of patients with traumatic brain injury: outcome at two, five, and ten years post-injury

The deleterious consequences of traumatic brain injury (TBI) impair capacity to return to many avenues of pre-morbid life. However, there has been limited longitudinal research examining outcome beyond five years post-injury. The aim of this study was to examine aspects of function, previously shown to be affected following TBI, over a span of 10 years. One hundred and forty one patients with TBI were assessed at two, five, and 10 years post-injury using the Structured Outcome Questionnaire. Fatigue and balance problems were the most common neurological symptoms, with reported rates decreasing only slightly during the 10-year period. Mobility outcomes were good in more than 75% of patients, with few participants requiring aids for mobility. Changes in cognitive, communication, behavioral, and emotional functions were reported by approximately 60% of the sample at all time points. Levels of independence in activities of daily living were high during the 10-year period, and as many as 70% of subjects returned to driving. Nevertheless, approximately 40% of patients required more support than before their injury. Only half the sample returned to previous leisure activities and fewer than half were employed at each assessment time post-injury. Although marital status remained stable over time, approximately 30% of participants reported difficulties in personal relationships. Older age at injury did not substantially alter the pattern of changes over time, except in employment. Overall, problems that were evident at two years post-injury persisted until 10 years post-injury. The importance of these findings is discussed with reference to rehabilitation programs.

White matter integrity in veterans with mild traumatic brain injury: associations with executive function and loss of consciousness

OBJECTIVE

We investigated using diffusion tensor imaging (DTI) and the association between white matter integrity and executive function (EF) performance in postacute mild traumatic brain injury (mTBI). In addition, we examined whether injury severity, as measured by loss of consciousness (LOC) versus alterations in consciousness (AOC), is related to white matter microstructural alterations and neuropsychological outcome.

PARTICIPANTS

Thirty Iraq and Afghanistan War era veterans with a history of mTBI and 15 healthy veteran control participants.

RESULTS

There were no significant overall group differences between control and mTBI participants on DTI measures. However, a subgroup of mTBI participants with EF decrements (n = 13) demonstrated significantly decreased fractional anisotropy of prefrontal white matter, corpus callosum, and cingulum bundle structures compared with mTBI participants without EF decrements (n = 17) and control participants. Participants having mTBI with LOC were more likely to evidence reduced EF performances and disrupted ventral prefrontal white matter integrity when compared with either mTBI participants without LOC or control participants.

CONCLUSIONS

Findings suggest that altered white matter integrity contributes to reduced EF in subgroups of veterans with a history of mTBI and that LOC may be a risk factor for reduced EF as well as associated changes to ventral prefrontal white matter.

The Community Integration Questionnaire: factor structure across racial/ethnic groups in persons with traumatic brain injury

OBJECTIVE

To examine the factor structure and construct validity of the Community Integration Questionnaire, a widely used measure of community participation among individuals with traumatic brain injury (TBI), among 3 racial/ethnic groups.

DESIGN

Prospective longitudinal cohort study.

SETTING

Enrollment in acute inpatient TBI rehabilitation with follow-up at 1 year after injury.

PARTICIPANTS

A total of 1756 persons with TBI enrolled in the Traumatic Brain Injury Model Systems (TBIMS) national Database.

MAIN OUTCOME MEASURE

Community Integration Questionnaire at 1 year after injury.

RESULTS

The goodness of fit for the factor structure of the Community Integration Questionnaire, separating items into Home Competency, Social Integration, and Productive Activity, was satisfactory for whites but not for blacks or Hispanics.

CONCLUSIONS

Clinicians and researchers should take race/ethnicity into account when utilizing measures of community integration.

Health-related quality of life in traumatic brain injury: is a proxy report necessary?

Despite its importance to care, clinicians and researchers often discount patient-reported outcomes in favor of proxy reports, in persons with traumatic brain injury (TBI). The rationale relates to concerns about lack of awareness of patients regarding their functioning. However, although lack of awareness occurs in some patients with severe TBI, or in TBI involving certain lesion locations, or very soon after injury, this conclusion has been overgeneralized. The objective of this study is to determine the validity of patient-reported health-related quality of life by evaluating its relationship to injury severity and more objective indices of outcome, in a representative series of adults with TBI. A consecutive sample of 374 persons with TBI at least 14 years old, and having a post-resuscitation Glasgow Coma Scale score ≤12, an acute seizure, or a CT scan showing TBI- related findings. Seventy-six percent (374/491) of the eligible survivors were assessed at 6 months post-injury on the Life Satisfaction Survey. The greatest decrease in satisfaction was in the ability to think and remember, work, receive adequate income, and participate in leisure and recreational activities. Dissatisfaction significantly related to the functional limitation in that area as judged by the patients themselves (p<0.001) or by someone who knew them well (p≤0.001). The most severely injured group reported the most dissatisfaction for 13 out of 17 areas assessed. Patients with TBI, in general, do not need a proxy to report on their behalf regarding their functional limitations or health-related quality of life.

The relationship between alcohol and cognitive functioning following traumatic brain injury

The present study aimed to examine the association between frequency and quantity of alcohol consumption and cognitive functioning following traumatic brain injury (TBI). Sixty moderately to severely injured individuals had completed the Alcohol Use Disorders Identification Test (AUDIT) to measure preinjury alcohol use soon after injury and were recruited and assessed with AUDIT and Time Line Follow-Back (TLFB), as a measure of frequency and quantity of alcohol consumption at 6-9 months post injury. Fifty participants completed both AUDIT and TLFB at a follow-up assessment at 12-15 months post injury. Measures of processing speed/attention, memory, and executive function were also administered. Regression analyses were used to examine the relationships between alcohol use and cognition at the two occasions of measurement. Harmful or hazardous alcohol use pre injury was associated with poorer memory performance on the California Verbal Learning Test (CVLT-II) and slower processing speed on Symbol Digit Modalities Test on average across postinjury measurement occasions, but not with executive functioning, measured by the Modified Six Elements Test (MSET) at 6-9 months post injury. On the other hand, executive functioning on MSET 6-9 months post injury was significantly poorer in participants who were consuming any alcohol at all in the month prior to follow-up assessment. The current study provides evidence showing that pre- and postinjury alcohol use is negatively associated with different aspects of cognitive functioning following TBI. In addition to providing some support for the provision of advice to abstain from alcohol after injury, these findings suggest that interventions to reduce postinjury alcohol use may be useful.

Accommodation Outcomes and Transitions Following Community-Based Intervention for Individuals with Acquired Brain Injury

Objectives: To explore living situation, support and participation outcomes of people with severe acquired brain injury (ABI) residing in either home-like or disability-specific accommodation settings, who were provided with 3 years of occupational therapy intervention based on the Community Approach to Participation (CAP).

To examine transitions for a subgroup whose accommodation and support model changed during this 3-year period and identify factors critical to this change.

Method: Forty-three participants who had sustained severe to extremely severe ABI, and were an average of 6.73 years post-injury, were provided with CAP intervention over a 3-year period. Living situation and support model, participation levels and accommodation transition data were collected at four time points.

Results: Participants were living in a range of home-like and disability-specific accommodation settings at baseline. The disability-specific accommodation group had mainly noncompensable injuries and required a significantly higher level of daily support at all four time points. They also received higher total hours of support, which averaged 170.83 hours per week at baseline and did not change significantly over the 3 years. In contrast, 86% of the participants residing in home-like settings had compensable injuries and received an average of 91.46 hours of support per week at baseline. This reduced to 70.97 hours per week over the 3-year intervention period, a change that was statistically significant.

Conclusion: It is possible to achieve accommodation transitions to more independent, home-like situations many years post-injury and regardless of injury severity. Home-like settings provide scope to adjust support along a continuum to reflect gains in independence, community integration and role participation that the fixed models and hours of support in disability-specific accommodation do not. Over time, these gains can flow into a significant reduction in hours of support.

Community Integration Following Severe Traumatic Brain Injury: Outcomes and Best Practice

Community integration is often cited as the ultimate aim of rehabilitation. However, outcome studies show that following severe traumatic brain injury (TBI), many people do not return to valued life roles or reach previous levels of integration within their community. More recent research, in association with extensive clinical experience, reveals significant variability in outcomes within this group. Although some people return to productive activity and maintain a network of family and friends, others lead lives characterised by boredom and loneliness. This paper has two aims. The first is to examine TBI community integration outcome literature and selected theoretical models. The second is to describe a Community Approach to Participation (CAP), an individualised and collaborative model of community-based practice, which endeavours to address the poor outcomes identified following TBI. The CAP will be illustrated in the detailed case study of Sarah.

Recovery of Impairments After Severe Traumatic Brain Injury: Findings From a Prospective, Multicentre Study

This study aimed to describe the recovery of impairments after severe traumatic brain injury (TBI) over a 3-year period. An inception cohort over 2 years was recruited from 11 brain injury rehabilitation units participating in a state-wide program. The 131 individuals with TBI were assessed at admission to the rehabilitation program, 18 months and 3 years post-trauma. This report described results from the Disability Rating Scale (DRS) and Mayo-Portland Adaptability Index (MPAI). Regression analyses, examining the influence of five acute injury variables on DRS and MPAI, revealed that posttraumatic amnesia (PTA) was a significant individual predictor. Data were thus analysed according to duration of PTA: 1 to 2 weeks (n= 19), 2 to 4 weeks (n= 44) and more than 4 weeks (n= 68). At program admission there was poorer overall level of functioning on the DRS in the longest PTA group, but no difference between the shorter PTA groups. Significant improvements occurred on the DRS for all PTA groups over the first 18 months posttrauma, with improvements continuing between 18 months and 3 years. At the 3-year follow-up, frequency data from the MPAI indicated that clinically significant impairments in mobility, hand function, communication and behaviour were uncommon in the shorter PTA groups, although 36% to 47% continued to experience cognitive impairments. Impairments were common in the longest PTA group in some areas, particularly cognition where two thirds or more continued to experience clinically significant impairments in attention, memory and novel problem-solving. These results confirm the predictive significance of PTA duration regarding longer-term level of recovery. They also highlight the limitation in classifying the ‘severe’ TBI category as an homogenous group: significant subgroup differences occurred on medical and functional variables at program admission, 18 months and 3 years posttrauma. These data further substantiate the persistence of neuropsychological impairments in the face of good physical recovery at all levels of severity within the severe TBI group.

Long-Term Outcome Following Traumatic Brain Injury

Objectives: To investigate care needs, functional outcome, role participation and community integration approximately nine years following severe brain injury. To gain an understanding of the ongoing cost of care and support needs for this group. Participants: 13 individuals who had sustained an extremely severe traumatic brain injury (TBI), between 8 and 9 years previously participated in the study. These individuals were the remaining participants of a larger sample of consecutive admissions between 1996 and 1998 at Ivanhoe Manor Rehabilitation Hospital. Measures: Structured Interview, Functional Independence Measure, Community Integration Questionnaire, Care and Needs Scale and Role Checklist. Results: The majority of the participants were reported to have high support needs, with 6 participants (46%) requiring 24-hour support. Four participants were reported to able to be left alone for between a few hours per day to almost all week. Three participants reported that they were completely independent. The participant's characteristics are described in terms of functional independence, community integration and role participation. Overall care needs appear to have remained relatively stable between 2 and 9 years postinjury. However, there was a shift in the proportion of paid and gratuitous care over time, with a decrease in paid care and increased gratuitous care noted from the 2-year to long-term follow-up time points. Conclusions: Severe TBI has a long term influence on life roles, care needs and functional independence. The current study suggests that high care needs do not necessarily preclude participants from leading active lives and participating in valued life roles. The importance of social support in facilitating participation in activity and the potential issues for caregiver burden, given the increase in gratuitous care over time, should be acknowledged and further research in this area is recommended.

Cost of disorders of the brain in Europe 2010

BACKGROUND

The spectrum of disorders of the brain is large, covering hundreds of disorders that are listed in either the mental or neurological disorder chapters of the established international diagnostic classification systems. These disorders have a high prevalence as well as short- and long-term impairments and disabilities. Therefore they are an emotional, financial and social burden to the patients, their families and their social network. In a 2005 landmark study, we estimated for the first time the annual cost of 12 major groups of disorders of the brain in Europe and gave a conservative estimate of €386 billion for the year 2004. This estimate was limited in scope and conservative due to the lack of sufficiently comprehensive epidemiological and/or economic data on several important diagnostic groups. We are now in a position to substantially improve and revise the 2004 estimates. In the present report we cover 19 major groups of disorders, 7 more than previously, of an increased range of age groups and more cost items. We therefore present much improved cost estimates. Our revised estimates also now include the new EU member states, and hence a population of 514 million people.

AIMS

To estimate the number of persons with defined disorders of the brain in Europe in 2010, the total cost per person related to each disease in terms of direct and indirect costs, and an estimate of the total cost per disorder and country.

METHODS

The best available estimates of the prevalence and cost per person for 19 groups of disorders of the brain (covering well over 100 specific disorders) were identified via a systematic review of the published literature. Together with the twelve disorders included in 2004, the following range of mental and neurologic groups of disorders is covered: addictive disorders, affective disorders, anxiety disorders, brain tumor, childhood and adolescent disorders (developmental disorders), dementia, eating disorders, epilepsy, mental retardation, migraine, multiple sclerosis, neuromuscular disorders, Parkinson's disease, personality disorders, psychotic disorders, sleep disorders, somatoform disorders, stroke, and traumatic brain injury. Epidemiologic panels were charged to complete the literature review for each disorder in order to estimate the 12-month prevalence, and health economic panels were charged to estimate best cost-estimates. A cost model was developed to combine the epidemiologic and economic data and estimate the total cost of each disorder in each of 30 European countries (EU27+Iceland, Norway and Switzerland). The cost model was populated with national statistics from Eurostat to adjust all costs to 2010 values, converting all local currencies to Euro, imputing costs for countries where no data were available, and aggregating country estimates to purchasing power parity adjusted estimates for the total cost of disorders of the brain in Europe 2010.

RESULTS

The total cost of disorders of the brain was estimated at €798 billion in 2010. Direct costs constitute the majority of costs (37% direct healthcare costs and 23% direct non-medical costs) whereas the remaining 40% were indirect costs associated with patients' production losses. On average, the estimated cost per person with a disorder of the brain in Europe ranged between €285 for headache and €30,000 for neuromuscular disorders. The European per capita cost of disorders of the brain was €1550 on average but varied by country. The cost (in billion €PPP 2010) of the disorders of the brain included in this study was as follows: addiction: €65.7; anxiety disorders: €74.4; brain tumor: €5.2; child/adolescent disorders: €21.3; dementia: €105.2; eating disorders: €0.8; epilepsy: €13.8; headache: €43.5; mental retardation: €43.3; mood disorders: €113.4; multiple sclerosis: €14.6; neuromuscular disorders: €7.7; Parkinson's disease: €13.9; personality disorders: €27.3; psychotic disorders: €93.9; sleep disorders: €35.4; somatoform disorder: €21.2; stroke: €64.1; traumatic brain injury: €33.0. It should be noted that the revised estimate of those disorders included in the previous 2004 report constituted €477 billion, by and large confirming our previous study results after considering the inflation and population increase since 2004. Further, our results were consistent with administrative data on the health care expenditure in Europe, and comparable to previous studies on the cost of specific disorders in Europe. Our estimates were lower than comparable estimates from the US.

DISCUSSION

This study was based on the best currently available data in Europe and our model enabled extrapolation to countries where no data could be found. Still, the scarcity of data is an important source of uncertainty in our estimates and may imply over- or underestimations in some disorders and countries. Even though this review included many disorders, diagnoses, age groups and cost items that were omitted in 2004, there are still remaining disorders that could not be included due to limitations in the available data. We therefore consider our estimate of the total cost of the disorders of the brain in Europe to be conservative. In terms of the health economic burden outlined in this report, disorders of the brain likely constitute the number one economic challenge for European health care, now and in the future. Data presented in this report should be considered by all stakeholder groups, including policy makers, industry and patient advocacy groups, to reconsider the current science, research and public health agenda and define a coordinated plan of action of various levels to address the associated challenges.

RECOMMENDATIONS

Political action is required in light of the present high cost of disorders of the brain. Funding of brain research must be increased; care for patients with brain disorders as well as teaching at medical schools and other health related educations must be quantitatively and qualitatively improved, including psychological treatments. The current move of the pharmaceutical industry away from brain related indications must be halted and reversed. Continued research into the cost of the many disorders not included in the present study is warranted. It is essential that not only the EU but also the national governments forcefully support these initiatives.

Perceptions of community integration in an ethnically diverse sample

OBJECTIVE

To investigate the meaning of community integration in an ethnically diverse sample.

DESIGN

Prospective study using mixed qualitative and quantitative methods.

SETTING

County level I trauma center.

PARTICIPANTS

Fifty-eight blacks, 57 Hispanics, and 52 whites with traumatic brain injury living in the community 6 months postinjury.

MAIN MEASURES

Open-ended interview questions and a questionnaire assessing perceived importance of community integration activities.

RESULTS

Resulting themes indicated that feeling part of the community was related to type and quality of community relationships, perceived safety and security, active involvement, feeling included and respected, and familiarity with the community. Themes regarding barriers included the following: environmental and social barriers; injury-related cognitive and physical changes; dissimilarities to others; relocation; and financial issues. Blacks and Hispanics placed more emphasis on domestic activities than did whites.

CONCLUSIONS AND IMPLICATIONS

Feeling integrated into the community relates to aspects of the environment as much as to involvement in specific activities. Environmental barriers can be just as important as injury-related changes. Different racial/ethnic groups place different value on participation activities. The results emphasize the importance of assessing subjective aspects of community integration, individualizing rehabilitation goals, and intervening in the environment to facilitate participation.

Relationship between psychiatric disorders and 1-year psychosocial outcome following traumatic brain injury

OBJECTIVE

To investigate the relationship of psychiatric functioning with psychosocial functioning at 1 year following traumatic brain injury (TBI), after controlling for relevant demographic, injury-related, and concurrent factors.

DESIGN

Prospective 1-year longitudinal study.

PARTICIPANTS

Participants were 122 individuals with TBI and 88 proxy informants.

SETTING

Rehabilitation hospital.

MAIN MEASURES

The Structured Clinical Interview for DSM-IV-TR (Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition, Text Revision)) Axis I Disorders, Hospital Anxiety and Depression Scale, Sydney Psychosocial Reintegration Scale, and Glasgow Outcome Scale--Extended.

RESULTS

At 1 year postinjury, occupational activities were the area of most change after TBI followed by interpersonal relationships and independent living skills, according to the Sydney Psychosocial Reintegration Scale. The majority of participants were rated as having moderate disability on the Glasgow Outcome Scale--Extended. After controlling for relevant background factors, preinjury, acute postinjury, and concurrent psychiatric disorders were significantly related to 1-year psychosocial outcome.

CONCLUSION

Screening in the acute postinjury stage for presence of preinjury psychiatric history or current distress may help identify individuals who require more intensive rehabilitation and psychiatric support and more active postdischarge monitoring. Further research exploring potential causal mechanisms for these findings is required.

Cognitive and behavioral impairment in traumatic brain injury related to outcome and return to work

OBJECTIVE

To evaluate the cognitive and behavioral disturbances related to return to work (RTW) in patients with traumatic brain injury (TBI) with the application of a differentiated outcome scale.

DESIGN

Longitudinal cohort study.

SETTING

Level I trauma center.

PARTICIPANTS

Adults (N=434) with TBI of various severity.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Extended Glasgow Outcome Scale (GOS-E), Differentiated Outcome Scale (DOS), and RTW.

RESULTS

Patients encountered problems in the physical (40%), cognitive (62%), behavioral (55%), and social domains (49%) of the DOS, with higher frequency related to severity of injury. Even those with mild TBI experienced cognitive (43%) and behavioral problems (33%). Patients with good recovery (58%) according to the GOS-E experienced problems in 1 or more domains of the DOS. Half the patients were able to resume previous vocational activities completely, although 1 in 3 experienced cognitive or behavioral problems. Using multivariate logistic regression analysis, the cognitive (odds ratio [OR], 10.548; confidence interval [CI], 5.99-18.67), behavioral (OR, 2.648; CI, 1.63-4.29), and physical domains (OR, 2.763; CI, 1.60-4.78) were significant (P<.01) predictors of RTW. For subcategories of TBI, the cognitive domain was predictive for RTW in those with moderate and severe TBI, whereas both the cognitive and behavioral domains were predictive for RTW in those with mild TBI.

CONCLUSIONS

With application of a more detailed outcome scale, cognitive and behavioral impairments interfering with RTW were present in a substantial part of patients with TBI in the chronic phase after injury. More research is needed exploring the cognitive and behavioral outcome in different categories of injury severity separately.

Measuring perceived difficulty in post-acute brain injury rehabilitation: The Sister Kenny Symptom Management Scale

PRIMARY OBJECTIVE

Patients' perceptions of difficulty managing symptoms contribute to disability after brain injury. This study introduces the Sister Kenny Symptom Management Scale (KSMS) and reports on its factor structure, reliability, validity and clinical value.

METHOD

Archived data from (overlapping) samples of patients with brain injuries of mixed aetiologies, seen at an outpatient clinic over 16 years were used in development and validation studies of the KSMS. Comparison measures included the Profile of Mood States (POMS), neuropsychological test scores and employment.

RESULTS

Factor analysis of 34 items (n = 328) identified five sub-scales with satisfactory internal consistency and test-re-test stability representing difficulty with executive functions, language, recent memory, aggressive behaviour and physical symptoms. A pattern of correlations (n = 336) with Profile of Mood States (POMS) sub-scales of similar and different content supported the concurrent validity of KSMS sub-scales. Only the Memory sub-scale correlated with its test index. The Language score and test index approached significance. The Executive sub-scale did not. Hierarchical regression analysis (n = 102) that included ratings of mood and symptom management showed that employment after discharge was only predicted by post-treatment ratings of difficulty with cognitive functions.

CONCLUSION

Self-assessments of difficulty managing symptoms can be reliably assessed and may contribute to understanding patients' disability, treatment response and future prospects.

How many people return to work after acquired brain injury?: a systematic review

PRIMARY OBJECTIVE

To investigate how many people return to work (RTW) after acquiring brain injury (ABI) due to traumatic or non-traumatic causes. Secondary objectives were to investigate the differences in outcome between traumatic and non-traumatic causes, the development of RTW over time and whether or not people return to their former job.

METHODS

A systematic literature search (1992-2008) was performed using terms of ABI and RTW. The methodological quality of the studies was determined. An overall estimation of percentage RTW 1 and 2 years post-injury was calculated by data pooling.

MAIN OUTCOMES AND RESULTS

Finally, 49 studies were included. Within 2 years post-injury, 39.3% of the subjects with non-traumatic ABI returned to work. Among people with traumatic ABI, 40.7% returned to work after 1 year and 40.8% after 2 years. No effect of cause or time since injury was found. Some people with traumatic ABI who returned to work were not able to sustain their job over time. Changes of occupation and job demands are common among people with ABI.

CONCLUSIONS

About 40% of the people with traumatic or non-traumatic ABI are able to return to work after 1 or 2 years. Among those with acquired traumatic brain injury a substantial proportion of the subjects were either not able to return to their former work or unable to return permanently.

Isolated severe traumatic brain injuries: association of blood alcohol levels with the severity of injuries and outcomes

BACKGROUND

Traumatic brain injury is a common cause of death after traumatic insults. Alcohol intoxication is a recognized contributor to the occurrence of these injuries. The specific effects of alcohol exposure on injury severity and subsequent outcomes, however, remain controversial. The aim of this study was to investigate the relationship between blood alcohol levels (BAL) and outcomes in patients with isolated severe traumatic brain injuries (sTBI).

METHODS

During the calendar year 2003, as part of a pilot project, the Los Angeles County Department of Health Services obtained routine BAL on all patients transported to any of its 13 trauma centers. This study analyzes the effect of BAL on outcomes in patients with isolated sTBI (head Abbreviated Injury Scale (AIS) score >or=3; extracranial AIS score <3). The Low/No ethanol (ETOH) group included patients with negative or low (<0.08 mg/dL) BAL. Patients with BAL >or=0.08 mg/dL constituted the high ETOH group. Logistic regression was performed to determine whether alcohol levels had an independent association with outcomes.

RESULTS

There were 815 patients with isolated severe head injuries. Overall, 468 patients (57%) constituted the Low/No ETOH group, and 347 (43%) the high ETOH group. Alcohol levels were not significantly associated with severity of injury, hypotension at admission, Glasgow Coma Scale score, incidence of major complications, and intensive care unit or hospital length of stay. However, adjusted mortality was significantly lower in the high ETOH group when compared with the Low/No ETOH (8.9% vs. 17.1%; adjusted odds ratio: 0.60, 95% confidence interval: 0.37-0.96, p = 0.037). In the subgroup of patients with Injury Severity Score >15 the relative risk for mortality in the high ETOH group was significantly lower than in patients with Low/No ETOH. There was also an increased survival with high ETOH in patients with Injury Severity Score >25, but this was not statistically significant.

CONCLUSIONS

Among patients with isolated sTBI, BAL do not seem to be associated with overall injury severity, head injury severity, or the occurrence of major morbidities. Similarly, hospital and intensive care unit lengths are not affected by high admission BAL level. The adjusted overall in-hospital mortality, however, is significantly lower in patients presenting with the high BAL (>or=0.08 g/dL) after isolated sTBI.

Social functioning after traumatic brain injury

OBJECTIVE

To determine the relationship between adult-onset traumatic brain injury (TBI) and social functioning including employment, social relationships, independent living, recreation, functional status, and quality of life 6 months or longer after injury.

PARTICIPANTS

Not applicable.

DESIGN

Systematic review of the published, peer-reviewed literature.

PRIMARY MEASURES

Not applicable.

RESULTS

Fourteen primary and 25 secondary studies were identified that allowed comparison to controls for adults who were at least 6 months post-TBI. TBI decreases the probability of employment after injury in those who were workers before their injury, lengthens the timing of their return if they do return to work, and decreases the likelihood that they will return to the same position. Those with moderate and severe TBI are clearly affected, but there was insufficient evidence of a relationship between unemployment and mild TBI. Penetrating head injury sustained in wartime is clearly associated with increased unemployment. TBI also adversely affects leisure and recreation, social relationships, functional status, quality of life, and independent living. Although there is a dose-response relationship between severity of injury and social outcomes, there is insufficient evidence to determine at what level of severity the adverse effects are demonstrated.

CONCLUSION

TBI clearly has adverse effects on social functioning for adults. While some consequences might arise from injuries to other parts of the body, those with moderate to severe TBI have more impaired functioning than do those with other injuries alone.

Coping strategies, social support, life orientation and health-related quality of life following traumatic brain injury

OBJECTIVE

To study coping strategies, social support and life orientation in patients following moderate and severe traumatic brain injury (TBI) in relation to health-related quality of life.

SUBJECTS

Eighty-five patients with moderate or severe TBI and 68 control persons.

METHODS

Estonian versions of the COPE-D test, the Brief Social Support Questionnaire, the Life Orientation Test and the RAND-36 questionnaire.

RESULTS

Persons with TBI reported using task-oriented and social/emotional support strategies less often and avoidance-oriented strategies more often than control persons (p < 0.05). The social support network, satisfaction with it and optimism as life orientation were lower in the patient group (p < 0.05). Task-oriented coping styles, satisfaction with social support and optimistic life orientation were associated with the majority of the domains of health-related quality of life and resuming work after TBI.

CONCLUSIONS

To achieve effective rehabilitation and to enhance patients' well-being, it is important to improve the quality and amount of social support network, as well as to support patients' adequate coping efforts for promoting an active lifestyle.

Computerized errorless learning-based memory rehabilitation for Chinese patients with brain injury: A preliminary quasi-experimental clinical design study

AIM

To evaluate the effectiveness of a computerized, errorless learning-based memory rehabilitation program for Chinese patients with traumatic brain injury (TBI).

METHODS

This study adopted a pre- and post-test quasi-experimental design. A total of 37 patients with TBI were randomly assigned to a Computer-Assisted Memory Training Group (CAMG), a Therapist-administered Memory Training Group (TAMG) and a Control Group (CG). Except for the CG, the patients in both the CAMG and TAMG groups received, respectively, 1-month memory training programmes that were similar in content but differed in delivery mode. All patients were followed up 1 month after treatment. The outcome measures that were taken were the Neurobehavioural Cognitive Status Examination (NCSE or Cognistat), the Rivermead Behavioural Memory Test (RBMT) and The Hong Kong List Learning Test (HKLLT). Repeated measure analyses were performed to investigate differences among the three groups.

RESULTS

The patients in the Computer-assisted Memory Rehabilitation (CAMG) and Therapist-administered Memory Rehabilitation group (TAMG) were found to perform better than the CG in the NCSE and RBMT, but no significant differences were found between the CAMG and TAMG. The CAMG showed significant improvement in their HKLLT assessment as compared with the TAMG and CG. No statistically significant differences were found between the CAMG and TAMG when comparing the post-training outcome measures with the follow-up results.

CONCLUSION

There is no difference between CAMG and TAMG, but the efficacy has been demonstrated when comparing with CG. It is suggested that the combined use of an errorless learning and a computerized approach may be an effective way of enhancing the memories of patients with TBI. This new method may smooth the progress of the whole human memory process and produce a better carryover treatment effect.

Exploring eye movement analysis as a measure of selective visual attention in brain injured individuals

PRIMARY OBJECTIVE

To investigate the utility of using a new method of assessment for deficits in selective visual attention (SVA).

METHODS AND PROCEDURES

An independent groups design compared six participants with brain injuries with six participants from a non-brain injured control group. The Sensomotoric Instruments Eye Movement system with remote eye-tracking device (eye camera) and two sets of eight stimuli were employed to determine if the camera would be a sensitive discriminator of SVA in these groups.

MAIN OUTCOMES AND RESULTS

The attention profile displayed by the brain injured group showed that they were slower, made more errors, were less accurate and more indecisive than the control group.

CONCLUSIONS

The utility of eye movement analysis as an assessment method was established, with implications for rehabilitation requiring further development.

Who benefits? Outcome following a coping skills group intervention for traumatically brain injured individuals

PRIMARY OBJECTIVE

To investigate the variables associated with positive psychological outcome following a group intervention for 33 individuals with traumatic brain injury.

RESEARCH DESIGN

Evaluation study which used multiple regression analysis to examine the variables associated with change in psychological adjustment following a 10-session cognitive behaviour therapy-based group.

METHODS AND PROCEDURES

The predictor variables were age at injury, time since injury, injury severity, self-awareness, pre-morbid intellectual function, memory function, executive function and level of depression and anxiety prior to intervention.

MAIN OUTCOMES AND RESULTS

The predictor variables contributed a significant proportion of the variance in percentage change in depression. The major finding was that better outcomes following intervention were associated with greater self-awareness of injury-related deficits.

CONCLUSIONS

The present study identified a number of variables that were associated with improvement in depression following psychological intervention and may assist future treatment resources to be directed most effectively.

The importance of vocal affect to bimodal processing of emotion: implications for individuals with traumatic brain injury

Persons with traumatic brain injury (TBI) often have difficulty recognizing emotion in others. This is likely due to difficulties in interpreting non-verbal cues of affect. Although deficits in interpreting facial cues of affect are being widely explored, interpretation of vocal cues of affect has received much less attention. Accurate interpretation of vocal affect cues is important, particularly when facial cues are absent or ambiguous. These cues also contribute to more accurate identification of emotion. The neural substrates of facial and vocal affect recognition appear to be shared, further contributing to improved bimodal processing. This article discusses the importance of vocal affect cues in interpreting emotion. Expression of vocal affect in persons with TBI is also briefly discussed since difficulty in controlling and manipulating vocal cues of emotion when speaking may also contribute to poor social outcomes. A review of the literature in acoustic parameters that contribute to identification and expression of emotions is followed by a discussion on the integration of visual and auditory cues in bimodal processing and the relationship between facial and vocal affect in persons with TBI.

LEARNING OUTCOMES

Readers will be able to: 1) Identify the parameters primarily used to describe the acoustic characteristics of vocal affect; 2) Describe the acoustic parameters typically associated with Anger, Fear, Happiness and Sadness; 3) Describe the difficulties experienced by persons with TBI in the perception and integration of facial and vocal cues of affect.

Community integration, social support and life satisfaction in relation to symptoms 3 years after mild traumatic brain injury

PRIMARY OBJECTIVE

To investigate the relation between psychosocial functioning (community integration, life satisfaction and social support) and symptoms (post-concussion, post-traumatic stress and depression) in persons with mild traumatic brain injury (MTBI) 3 years after the trauma.

METHODS

Population-based follow-up study of 163 patients. At follow-up, an assessment of community integration, social support, life satisfaction and symptoms was made.

RESULTS

Total score of Community Integration Questionnaire (CIQ) was negatively correlated to total score of the Rivermead Post-Concussion Symptoms Questionnaire (RPQ, r = -0.270, p < 0.001) and to total score of the Beck Depression Inventory (BDI, r = -0.332, p < 0.001). Life satisfaction (LiSat-11) was negatively correlated to the RPQ (r = -0.459, p < 0.001), to total score of the Impact of Event Scale (IES, r = -0.365, p < 0.001) and to the BDI (r = -0.642, p < 0.001). Low levels of life satisfaction were common at follow-up.

CONCLUSIONS

A large proportion of the individuals with MTBI experienced both psychosocial difficulties, with low levels of life satisfaction in particular and symptoms (post-concussion, post-traumatic stress and depression) 3 years after trauma. Since the possibility of pre-injury factors contributing to the condition at follow-up cannot be ruled out, the study indicates that all these factors should be taken into consideration in the management of persons with MTBI.

Long-term morbidities following self-reported mild traumatic brain injury

The objective of this study was to examine the prevalence of long-term psychiatric, neurologic, and psychosocial morbidities of self-reported mild traumatic brain injury (MTBI). A cross-sectional cohort sample of three groups was examined: those who had not been injured in a motor vehicle accident nor had a MTBI (n = 3,214); those who had been injured in an accident but did not have a MTBI (n = 539); and those who had a MTBI with altered consciousness (n = 254). Logistic regression analyses were used to model odds ratios for the association between group and outcome variables while controlling demographic characteristics, comorbid medical conditions, and early-life psychiatric problems. Compared with uninjured controls, MTBI increased the likelihood of depression and postconcussion syndrome. MTBI also was associated with peripheral visual imperceptions and impaired tandem gait. Similarly, the MTBI group had poorer psychosocial outcomes including an increased likelihood of self-reported disability, underemployment, low income, and marital problems. Results suggest that MTBI can have adverse long-term psychiatric, neurologic, and psychosocial morbidities.

Le Profil du Loisir, un instrument prometteur en ergothérapie

Description : Les bienfaits du loisir sont bien connus, mais peu d'instruments ont été conçus dans l'optique de mesurer l'engagement d'une personne dans ses loisirs et d'évaluer les facteurs personnels ou environnementaux qui diminuent sa capacité de s'y engager. But : Cet article à pour but de présenter les étapes du développement du Profil du Loisir entre 1990 et 2002. Méthodologie : La planification, la construction et la validation de l'outil ont été faites selon les étapes de Benson et Clark (1982). Les premières versions ont été expérimentées par des ergothérapeutes auprès de personnes ayant eu un traumatisme cranio-cérébral. Résultats : La validation a permis l'élaboration de la version finale (3.0). L'outil présente une fidélité inter-juges allant de acceptable (kappa 0,21–0,4) à très bien (0,61–0,80) et test-retest de acceptable à modérée (0,41–0,60). Conséquences pour la pratique : Le Profil du Loisir s'avère prometteur pour amener les ergothérapeutes à considérer le loisir dans leur pratique et à l'évaluer de façon systématique.

Determinants of long-term functional consequences after major trauma

OBJECTIVE

The purpose of this study was to describe the long-term functional consequences from major trauma and to quantify the effect of sociodemographic, injury-related, and physical determinants of its outcome.

METHODS

A prospective cohort study was performed at the University Medical Center Utrecht (Level I trauma center) in the Netherlands during 1999 and 2000. All severely (injury severity score [ISS] >or=16) injured adult (age >or=16) trauma survivors (n = 359) were selected for follow-up. Between 12 and 18 months after trauma, outcome was assessed by means of Glasgow Outcome Scale (GOS), EuroQol (EQ-5D), and cognitive complaints.

RESULTS

Follow-up assessments (overall response rate 93%) were obtained of 335 patients (249 men, 86 women) with a mean age of 38 years (SD = 17) and a mean ISS of 25 (SD = 10.6). The mean visual analog scale score on the EuroQol (EQvas) was 73.5 (SD = 17.8) and the mean utility score (EQus) was 69.1 (SD = 29.9), both below the norm. Patients reported limitations of mobility (48%); self-care (18%); daily activities (55%); pain and discomfort (63%); anxiety or depression (28%); and cognitive complaints (65%). In multivariate analyses, injury localization (spinal cord injury, lower extremity injury, or brain injury) was significantly associated with EQvas, EQus, and other outcome measures. Educational level was significantly associated with EQvas, anxiety/depression, and cognitive complaints. Comorbidity was significantly associated with EQvas, EQus, all dimensions of the EQ-5D (except anxiety/depression), and cognitive complaints.

CONCLUSION

In addition to the injury localization, educational level and comorbidity were identified as important independent predictors of long-term functional consequences after major trauma. These determinants need further attention in outcome research and clinical practice.

Evaluation of a coping skills group following traumatic brain injury

PRIMARY OBJECTIVE

To examine the impact of a cognitive behaviour therapy (CBT) based intervention programme, termed the Coping Skills Group (CSG), on coping strategy use and emotional adjustment.

RESEARCH DESIGN

Thirty-one individuals with TBI participated and a wait-list control design was used.

METHODS AND PROCEDURES

The CSG ran twice a week, for 5 weeks and focused on developing adaptive coping skills for the management of emotional and adjustment issues.

MAIN OUTCOMES AND RESULTS

Following the CSG, the majority of participants subjectively reported that they had a better understanding of emotional issues and an improved ability to implement strategies to manage these issues. Adaptive coping, as measured on the Coping Scale for Adults, increased significantly immediately following intervention. However, no significant changes in anxiety, depression, self-esteem and psychosocial function were observed on the measures used.

CONCLUSIONS

The results suggest that it may be possible to modify coping strategy use following brain injury, through CBT.

Self-Reported Psychosocial Health Among Adults With Traumatic Brain Injury

OBJECTIVE

To measure the subjective psychosocial health of a population-based sample of adults with traumatic brain injury (TBI).

DESIGN

Retrospective, cohort study involving a 1-year postinjury interview.

SETTING

Sixty-two acute care, nonfederal hospitals in South Carolina.

PARTICIPANTS

Persons (> or =15y) hospitalized with TBI.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

The psychosocial health scales of the Medical Outcomes Study 36-Item Short-Form Health Survey.

RESULTS

Of the 7612 participants, 29% reported poor psychosocial health. Factors associated with poor psychosocial well-being included younger age, female sex, Medicaid coverage, no health insurance, inadequate or moderate social support, comorbidities (eg, a preinjury substance abuse problem), cognitive complaints, and some or a lot of limitation with activities of daily living. Only 36% of participants who reported poor psychosocial health reported receiving any mental health services.

CONCLUSIONS

A substantial proportion of persons hospitalized with TBI reported poor psychosocial health at 1 year postinjury. To optimize recovery, clinicians need to ensure that patients' psychosocial health needs are addressed during the postacute period.

Evaluation of a community-based model of rehabilitation following traumatic brain injury

In recent years there has been a growing trend towards community-based post-acute rehabilitation for individuals with traumatic brain injury (TBI), as opposed to the traditional centre-based model, based on the premise that these individuals will learn more effectively in settings where they usually have to perform. In the present study, outcomes at two years post-injury in 77 individuals with TBI, treated within the community were compared on measures of activities of daily living (ADL), vocational status, and emotional adjustment with those of 77 TBI patients individually matched for gender, age, education, occupation, post-traumatic amnesia (PTA) duration, Glasgow Coma Scale (GCS) score and time in inpatient rehabilitation, who had attended the hospital for outpatient therapy. There were no significant differences between groups in terms of employment outcomes or independence in personal or domestic ADL. However those treated in the community were less likely to be independent in shopping and financial management and reported more changes in communication and social behaviour. Due to constraints of time and resources, these patients had received fewer one-on-one therapy sessions and thus treatment costs were somewhat lower. Attendant care costs were also lower in the community treatment group. Strengths and weaknesses of community-based post-acute rehabilitation are discussed.

A Longitudinal Study of Health-Related Quality of Life After Traumatic Brain Injury

OBJECTIVE

To examine the longitudinal course of health-related quality of life from 1 month to 3 to 5 years after traumatic brain injury (TBI).

DESIGN

Longitudinal cohort study with 4 evaluation points.

SETTING

Level I trauma center.

PARTICIPANTS

Consecutive hospital admissions of 133 adolescents and adults with complicated mild to severe TBI who completed the outcome measure at all 4 time points, 111 general trauma patients, and 87 healthy friend controls.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

Sickness Impact Profile.

RESULTS

TBI patients reported significant limitations at 1 month postinjury, with substantial improvement occurring by 6 months, especially in the physical domain. Psychosocial improvement was smaller, and perceived cognitive, emotional, and communication difficulties did not change over the time period assessed. Persons with TBI had clear difficulties relative to healthy peers, but their reported level of difficulties was very similar to that of the persons who had sustained a general trauma by 1 year postinjury.

CONCLUSIONS

In this sample, TBI was associated with significant early limitations in most aspects of everyday life. Considerable improvement was noted over the first 6 months postinjury, especially in physical domains. Some aspects of psychosocial functioning also improved, although reported limitations in communication, cognitive, and emotional domains remained constant over time. These findings highlight the persistence of injury-related difficulties that compromise quality of life.

Coping and Emotional Adjustment Following Traumatic Brain Injury

OBJECTIVES

To examine the association between coping style and emotional adjustment following traumatic brain injury.

PARTICIPANTS

Thirty three individuals who had sustained a traumatic brain injury (mean duration of posttraumatic amnesia = 32 days) between 1(1/2) months and almost 7 years previously.

MEASURES

Coping Scale for Adults, Hospital Anxiety and Depression Scale, Rosenberg Self-Esteem Scale, State-Trait Anger Expression Inventory, and the Sickness Impact Profile.

RESULTS

Approximately 50% of the sample reported clinically significant levels of anxiety and depression. Coping characterized by avoidance, worry, wishful thinking, self-blame, and using drugs and alcohol was associated with higher levels of anxiety, depression, and psychosocial dysfunction and lower levels of self-esteem. Coping characterized by actively working on the problem and using humor and enjoyable activities to manage stress was associated with higher self-esteem. Lower premorbid intelligence (measured via the National Adult Reading Test) and greater self-awareness (measured via the Self-Awareness of Deficits Interview) were associated with an increased rate of maladaptive coping.

CONCLUSIONS

The strong association between the style of coping used to manage stress and emotional adjustment suggests the possibility that emotional adjustment might be improved by the facilitation of more adaptive coping styles. It is also possible that improving emotional adjustment may increase adaptive coping. The development and evaluation of interventions aimed at facilitating adaptive coping and decreasing emotional distress represent important and potentially fruitful contributions to enhancing long-term outcome following brain injury.
