The relationship between the subclavian vessels and brachial plexus and the overlying clavicle: Anatomical study with application to plate osteosynthesis

A subclavian artery aneurysm after clavicle fracture and plate osteosynthesis in a suspected case of a screw that was too long led us to investigate body donor cadavers. The aim was to verify clavicle variability, and the course of the neurovascular bundle in relation to the clavicle and to the osteosynthesis plate, in order to clarify safe zones for plate and screw fixation. We used one fresh frozen and 25 embalmed donors for in situ measurements: (1) length and craniocaudal thickness of the clavicle, (2) distances between the sternal end of the clavicle and the center of parts of the neurovascular bundle. The clavicle was 15.15 cm long. The mean distances from the sternal end of the clavicle were 5.62 cm to the subclavian vein, 6.75 cm to the subclavian artery and 8.42 cm to the cords of the brachial plexus. The subclavius muscle was 1 cm thick. Because of sex differences in length and distances, we recorded the distances between the sternal end and parts of the neurovascular bundle as ratios of clavicle length (at-risk area) to provide sex-independent parameters: 0.379 for the vein, 0.449 for the artery and 0.554 for the nerve. The neurovascular bundle runs below the clavicle between the medial fourth and three fifths of clavicle length. To avoid iatrogenic neurovascular injuries, special caution is necessary during drilling and screwing the osteosynthesis. We also recommend using screws shorter than 1.4 cm.

[Does the hand solely belong in the hands of a qualified hand surgeon?]

Background In Germany, Hand Surgery is an additional qualification that can only be obtained by a three-year training after a completed residency in General Surgery, Plastic Surgery or Trauma and Orthopaedic Surgery. Nevertheless, injuries and diseases of the hand are also treated by physicians without this particular qualification. It is questionable whether these treatments more often lead to medical malpractice. Material and Methods 376 charges of medical malpractice in surgical treatments of the hand and forearm that were closed in 2014 and 2015 were collected by the Arbitration Board for Medical Liability Issues of the Medical Association of North Germany.Cases with proven medical malpractice were classified by the qualification of the physician in charge and analysed. A statistical analysis was performed with the use of the program SPSS (IBM). Results Medical malpractice was proven in 42 of 113 cases with an attending physician who held the additional qualification for Hand Surgery (37.2 %). For physicians without this qualification, the figures were 79 out of 155 (51.0 %) in the group of trauma and orthopaedic surgeons and 54 out of 108 (50.0 %) in the group of general surgeons. The differences between the hand surgeons and the trauma and orthopaedic surgeons (p = 0.017) and between hand surgeons and general surgeons were significant (p = 0.037). Conclusions It was shown that physicians with an additional qualification in hand surgery had signifcantly fewer proven medical malpratice cases than physicians without this qualification. The following trends were observed in the cases of the physicians without the additional qualification in hand surgery: underestimation of the severity of trauma to soft tissues and infections of the hand, errors in the surgical examination of the hand, including functional tests of tendons and nerves, as well as in diagnostic findings after X-ray studies of the hand.

Brain lesion correlates of fatigue in individuals with traumatic brain injury

The purpose of this study was to investigate the neurological correlates of both subjective fatigue as well as objective fatigability in individuals with traumatic brain injury (TBI). The study has a cross-sectional design. Participants (N = 53) with TBI (77% male, mean age at injury 38 years, mean time since injury 1.8 years) underwent a structural magnetic resonance imaging (MRI) scan and completed the Fatigue Severity Scale (FSS), while a subsample (N = 36) was also tested with a vigilance task. While subjective fatigue (FSS) was not related to measures of brain lesions, multilevel analyses showed that a change in the participants' decision time was significantly predicted by grey matter (GM) lesions in the right frontal lobe. The time-dependent development of the participants' error rate was predicted by total brain white matter (WM) lesion volumes, as well as right temporal GM and WM lesion volumes. These findings could be explained by decreased functional connectivity of attentional networks, which results in accelerated exhaustion during cognitive task performance. The disparate nature of objectively measurable fatigability on the one hand and the subjective experience of fatigue on the other needs further investigation.

The factorial and discriminant validity of the German version of the Post-traumatic Growth Inventory in stroke patients

Post-traumatic growth (PTG) is the experience of positive changes that can follow a traumatic event. The current study examined the factorial as well as the discriminant validity of the German version of the Post-traumatic Growth Inventory (PTGI-G) in stroke patients. A total of 188 adult stroke patients (63.3% male; median age 69 years) completed the PTGI-G and the German version of the Hospital Anxiety and Depression Scale (HADS-D) at the end of their inpatient rehabilitation. Confirmatory factor analyses indicate an acceptable model fit of both the original five-factor solution as well as a second-order factor model of the PTGI-G (CFI > .95; RMSEA < .01). Small and non-significant correlations between the PTGI-G subscales and the depression scale of the HADS-D support the discriminant validity of the PTGI-G. The PTGI-G appears to be a valid tool in the context of stroke research.

Is it dangerous to fantasize revenge in imagery exercises? An experimental study

BACKGROUND

Imagery rescripting (ImRS), i.e. changing intrusive mental images in imagery, is increasingly recognized as a helpful therapy technique. In ImRS exercises, patients sometimes suggest taking violent revenge on perpetrators. However, it is unclear whether vengeful phantasies can be particularly helpful in giving back feelings of power and control, or whether they rather increase aggressive feelings, with potentially harmful effects.

METHODS

Forty-six healthy participants watched 3 trauma movie segments depicting interpersonal violence. After each movie, one of 3 ImRS strategies (ImRS with violent revenge, ImRS without violence, safe place imagery) was applied. Dependent variables were subjective emotion ratings.

RESULTS

Aggressive and positive emotions changed most strongly with the safe place image, no differences between ImRS with and without violence were observed. Sad and anxious emotions were not differently influenced by different strategies.

LIMITATIONS

Only a healthy sample with no previous display of aggression has been investigated. Cross-over effects cannot be excluded due to the within-group design with repeated trauma movie segments.

CONCLUSIONS

Using violent pictures in ImRS does not seem to be particularly risky as it does not increase aggressive emotions in the participants; however it has no added value. For the purpose of emotion regulation after an analog trauma, the safe place imagery does best.

Motivational interviewing and cognitive behaviour therapy for anxiety following traumatic brain injury: a pilot randomised controlled trial

Although cognitive-behavioural therapy (CBT) is the treatment of choice for anxiety, its delivery needs to be adapted for individuals with traumatic brain injury (TBI). It also requires clients' active engagement for maximum benefit. This study was a pilot randomised controlled trial involving an anxiety treatment programme adapted for people with TBI, based on CBT and motivational interviewing (MI). Twenty-seven participants with moderate/severe TBI (aged 21-73 years, 78% males) recruited from a brain injury rehabilitation hospital were randomly allocated to receive MI + CBT (n = 9), non-directive counselling (NDC) + CBT (n = 10) and treatment-as-usual (TAU) (n = 8). CBT and MI were manualised and delivered in 12 weekly individual sessions. Primary outcome was self-reported anxiety symptoms assessed at baseline, at the end of NDC/MI and immediately following CBT. Assessment was conducted by assessors blinded to group assignment. Intention-to-treat analyses showed that the two active treatment groups demonstrated significantly greater anxiety reduction than TAU. Participants receiving MI showed greater response to CBT, in terms of reduction in anxiety, stress and non-productive coping, compared to participants who received NDC. The results provided preliminary support for the adapted CBT programme, and the potential utility of MI as treatment prelude. Longer follow-up data are required to evaluate the maintenance of treatment effects.

The Relationship Between Physical Fitness and Work Integration Following Stroke

Objective:To investigate the relationship between physical fitness and work integration following stroke.Design:Single-group study, measurement of physical fitness pre and post physical training, measurement of employment status in a follow-up assessment 2 to 36 months after rehabilitation.Setting:Interdisciplinary outpatient rehabilitation program.Participants:58 stroke survivors (62% male, mean age at program start 46.7 years, mean time since stroke 1.1 years) who were consecutively referred to the program.Intervention:1½ hours of intensive training of cardiorespiratory fitness and muscle strength 1–3 times weekly as part of the 3-month program.Measures:Physical fitness was measured with a modified Harvard Step Test, the Åstrand Cycling Test, and walking/running speed. The type of participants' employment as well as the amount of working hours was registered.Results:Good physical fitness as measured by the Harvard Step test, but not the Åstrand Cycling Test and walking/running speed, was related to return to competitive, full-time employment. Test results from training tended to predict work reintegration better than test results from training start. Improvement of physical fitness as measured by the Harvard Step Test was also related to follow-up employment.Conclusions:The results imply a relationship between physical fitness and work integration following stroke and should be confirmed with a randomised controlled study design.

Two-Year Outcome Following Traumatic Brain Injury and Rehabilitation: A Comparison of Patients From Metropolitan Melbourne and Those Residing in Regional Victoria

Background and Objective:Victoria's trauma management system provides acute care and rehabilitation following traumatic brain injury (TBI), with care of more complex injuries generally provided in specialist centres in metropolitan Melbourne. Little is known about how the outcomes of TBI survivors living in metropolitan Melbourne compare to those who reside in regional Victoria once they return to their community, where support services may be less available. The aim of the present study was to compare, in TBI individuals who have been treated at an inner-city rehabilitation centre in Melbourne, the long-term outcomes of those who live in metropolitan Melbourne (termed ‘Metro’) with those who reside in regional Victoria, termed ‘Regional.’Design and participants:Comparative study with quantitative outcome measures. A total of 959 patients, of whom 645 were designated ‘metro’ and 314 ‘regional’, were followed-up routinely at 2 years post-injury.Outcome measures:Structured Outcome Questionnaire, Glasgow Outcome Scale — Extended, Sickness Impact Profile, Craig Handicap Assessment and Reporting Technique, Hospital Anxiety and Depression Scale, Alcohol Use Disorders Identification Test and Drug Abuse Screening Test.Results:Few differences in outcomes were found between groups. However, after controlling for group differences in age and injury severity, some non-significant trends were suggestive of better outcomes in terms of less social isolation and anxiety and fewer dysexecutive behaviours in regional dwellers.Conclusions:These findings suggest that outcomes in patients from regional areas are at least as good as those from metropolitan Melbourne.

The nature, frequency and course of psychiatric disorders in the first year after traumatic brain injury: a prospective study

BACKGROUND

Psychiatric disorders are common following traumatic brain injury (TBI). However, few studies have examined the course of disorder development and the influence of pre-injury psychiatric history. The present study aimed to examine the frequency of, and association between, psychiatric disorders occurring pre- and post-injury, and to examine the post-injury course of disorders.

METHOD

Participants were 102 adults (75.5% male) with predominantly moderate-severe TBI. Participants were initially assessed for pre-injury and current disorders, and reassessed at 3, 6 and 12 months post-injury using the Structured Clinical Interview for DSM-IV Disorders (SCID).

RESULTS

Over half of the participants had a pre-injury psychiatric disorder; predominantly substance use, mood, and anxiety disorders. In the first year post-injury, 60.8% of participants had a psychiatric disorder, commonly anxiety and mood disorders. Post-injury disorders were associated with the presence of a pre-injury history (p<0.01), with 74.5% of participants with a pre-injury psychiatric history experiencing a post-injury disorder, which commonly presented at initial assessment or in the first 6 months. However, 45.8% of participants without a pre-injury history developed a novel post-injury disorder, which was less likely to emerge at the initial assessment and generally developed later in the year.

CONCLUSIONS

Despite evidence that most post-injury psychiatric disorders represent the continuation of pre-existing disorders, a significant number of participants developed novel psychiatric disorders. This study demonstrates that the timing of onset may differ according to pre-injury history. There seem to be different trajectories for anxiety and depressive disorders. This research has important implications for identifying the time individuals are most at risk of psychiatric disorders post-injury.

The association between apolipoprotein E and traumatic brain injury severity and functional outcome in a rehabilitation sample

Traumatic brain injury (TBI) can result in significant disability, but outcome is variable. The impact of known predictors accounts for a limited proportion of the variance in outcomes. Apolipoprotein E (ApoE) genotype has been investigated as an additional source of variability in injury severity and outcome, with mixed findings reflecting variable methodology and generally limited sample sizes. This study aimed to examine whether possession of the ApoE ɛ4 allele was associated with greater acute injury severity and poorer long-term outcome in patients referred for rehabilitation following TBI. ApoE genotype was determined for 648 patients with TBI, who were prospectively followed up a mean of 1.9 years post-injury. Hypotheses that ɛ4 carriers would have lower Glasgow Coma Scale (GCS) scores and longer post-traumatic amnesia (PTA) duration were not supported. Prediction of worse Glasgow Outcome Scale-Extended (GOSE) scores for ɛ4 carriers was supported with greater susceptibility seen in females. These results indicate the ApoE ɛ4 allele may be associated with poorer long-term outcome, but not acute injury severity. Possible mechanisms include differential effects of the ɛ4 allele on inflammatory and cellular repair processes, and/or amyloid deposition.

Prediction of functional and employment outcome 1 year after traumatic brain injury: a structural equation modelling approach

BACKGROUND

Traumatic brain injury (TBI) can cause lasting functional changes and lead to unemployment. The purpose of this study was to create and test a structural equation model (SEM) of the prediction of functional and employment outcome after TBI.

METHODS

Participants were 949 individuals with predominantly moderate to severe TBI (74% males, median age 25.7 years) who attended a follow-up interview 1 year post-injury. Outcome (employment and mood, cognitive and behavioural changes) was measured using the Structured Outcome Questionnaire. An SEM, based on existing research, was developed, tested and modified.

RESULTS

A comparative fit index of 0.99 and a root mean square error of approximation of 0.03 supported the fit of the final model. Age, education, pre-injury employment, injury severity and limb injuries were direct predictors of employment outcome. Gender, pre-injury psychiatric disorders and limb injuries were related to employment outcome by their association with mood, cognitive and behavioural changes.

CONCLUSIONS

The results demonstrate the complex interplay between various factors predicting outcome after TBI and provide evidence for the importance of tailoring rehabilitation to the individual's needs. Further research, including other conditions, can build on this model and include additional predictor and outcome measures.

The relationship between mood disorders and MRI findings following traumatic brain injury

BACKGROUND

High rates of depression have been reported in individuals with traumatic brain injury (TBI). The purpose of the current study was to investigate the relationship between structural MRI findings and the development of novel cases of post-injury depression in this population

METHODS

The study has a cross-sectional design. Assessments were conducted on average 2.2 years post-injury. Participants were 54 individuals (76% male, mean age 35 years, median PTA duration 16 days) who had sustained a TBI. Depression was assessed with the Structured Clinical Interview for DSM-IV (SCID-IV). Structural MRI scans were performed with a 1.5 Tesla machine.

RESULTS

The presence of lesions in the frontal, temporal, parietal and the sublobar regions was not related to depression. However, an imbalance of left vs right frontal and parietal viable brain volumes was related to the development of depression.

DISCUSSION

These findings are in support of Heller's model of emotion processing, but should be replicated using larger samples. Potential clinical implications are discussed in the manuscript.

Patient compliance in brain injury rehabilitation in relation to awareness and cognitive and physical improvement

The purpose of the present study was to investigate the relationship between patients' compliance and awareness and outcome of brain injury rehabilitation. Subjects were 98 patients who underwent a holistic neuropsychological outpatient rehabilitation programme. Patients had suffered a traumatic brain injury (n = 26), a cerebrovascular accident (n = 58), or another neurological insult (n = 14).

MEASURES

Two staff members, a neuropsychologist and a physiotherapist, retrospectively and separately rated patients' awareness and their compliance. Outcome was measured with the d2 test of concentration, measures of oxygen uptake, strength endurance, running speed, and patients' and relatives' ratings of patients' cognitive, physical, and overall problems on the European Brain Injury Questionnaire (EBIQ). The discrepancy between patients' and relatives' ratings on the EBIQ was incorporated as a second measure of patients' awareness.

RESULTS

The neuropsychologist's compliance ratings were significantly related to measures of insight, improvement of d2 performance accuracy and stability, improvement of oxygen uptake, and reduction of cognitive and overall problems as reported by the patients, while the physiotherapist's compliance ratings were related to measures of insight, improvement of d2 performance speed, improvement of oxygen uptake and strength endurance, and all three EBIQ patient scales.

DISCUSSION

The results suggest a differential relationship between situation-specific compliance and outcome.

The factor structure of the Hospital Anxiety and Depression Scale in individuals with traumatic brain injury

There is a lack of validated scales for screening for anxiety and depression in individuals with traumatic brain injury (TBI). The purpose of this study was to examine the factor structure of the Hospital Anxiety and Depression Scale (HADS) in individuals with TBI. A total of 294 individuals with TBI (72.1% male; mean age 37.1 years, S.D. 17.5, median post-traumatic amnesia (PTA) duration 17 days) completed the HADS 1 year post-injury. A series of confirmatory factor analyses was conducted to examine the fit of a one-, two- and three-factor solution, with and without controlling for item wording effects (Multi-Trait Multi-Method approach). The one-, two- or three-factor model fit the data only when controlling for negative item wording. The results are in support of the validity of the original anxiety and depression subscales of the HADS and demonstrate the importance of evaluating item wording effects when examining the factor structure of a questionnaire. The results would also justify the use of the HADS as a single scale of emotional distress. However, even though the three-factor solution fit the data, alternative scales should be used if the purpose of the assessment is to measure stress symptoms separately from anxiety and depression.

The Relationship between age, injury severity, and MRI findings after traumatic brain injury

Age and injury severity are among the most significant predictors of outcome after traumatic brain injury (TBI). However, only a few studies have investigated the association between, age, injury severity, and the extent of brain damage in TBI. The purpose of this study was to investigate the association between age, measures of injury severity, and brain lesion volumes, as well as viable brain volumes, following TBI. Ninety-eight individuals with mild to very severe TBI (75.5% male, mean age at injury 34.5 years) underwent a structural MRI scan, performed with a 1.5-Tesla machine, on average 2.3 years post-injury. Lesion volumes were highly skewed in their distribution and were dichotomized for statistical purposes. Measures of injury severity were Glasgow Coma Scale score (GCS) and duration of post-traumatic amnesia (PTA). Logistic regression analyses predicting lesion volumes, controlling for participants' gender, cause of injury, time from injury to MRI scan, and total brain volume, revealed that both older age and longer PTA were associated with larger lesion volumes in both grey and white matter in almost all brain regions. Older age was also associated with smaller viable grey matter volumes in most neo-cortical brain regions, while longer PTA was associated with smaller viable white matter volumes in most brain regions. The results suggest that older age worsens the impact of TBI on the brain. They also indicate the validity of duration of PTA as a measure of injury severity that is not just related to one particular injury location.

Factors contributing to attentional impairments after traumatic brain injury

The aim of the present study was to investigate the contribution of impaired information processing speed and strategic control of attention to performance on attentional tasks after traumatic brain injury (TBI). Forty moderately to severely injured rehabilitation inpatients and 40 healthy controls completed a selection of attentional tasks. Slowed processing speed in the TBI group was identified on the Symbol Digit Modalities Test (SDMT), 2&7 Selective Attention Test (2&7), Selective Attention (SAT), and Four Choice Reaction Time (4CRT) tasks. Impaired working memory was evident on the Letter Number Sequencing (LNS) task. Structural equation modeling revealed that the group difference in RT on the complex SAT was accounted for by slowed speed of processing on the simple SAT, and not working memory. TBI participants made more errors and missed responses on the complex version of the SAT, suggesting impairment in some aspects of strategic control of attention, and appeared unable to benefit from the automatic condition of the 2&7 Test. There was little evidence of deficit on the Sustained Attention to Response Task (SART). The present study provides evidence for a significant contribution of slowed processing speed to impaired performance on attentional tasks after TBI.

The development of the therapeutic working alliance, patients’ awareness and their compliance during the process of brain injury rehabilitation

PURPOSE

To examine the development and interaction of the therapeutic alliance, patients' compliance and awareness during the process of brain injury rehabilitation and the role of demographic and injury related variables in this process. Subjects were 86 patients who underwent a holistic neuropsychological outpatient rehabilitation programme. Patients had suffered a traumatic brain injury (n = 27), a cerebrovascular accident (n = 49) or another neurological insult (n = 10).

MEASURES

The therapeutic alliance between clients and their primary therapists, clients' awareness and their compliance were rated four times during the 14-week rehabilitation programme. The therapeutic alliance was rated by both clients and therapist using the Working Alliance Inventory (WAI), awareness and compliance were rated by the therapists.

RESULTS

The development of the process measures over time is described in the article. Clients' and therapists' perspectives on their alliance tended to converge over time. Clients' experience of their emotional bond with their therapist added as much to the prediction of clients' awareness as the localization of their brain injury. Clients' awareness was related to their compliance and mediated the impact of the therapeutic alliance on their compliance.

DISCUSSION

A good working alliance is the basis of successful rehabilitative work. The article discusses therapeutic implications of the results.

Subjective outcome of brain injury rehabilitation in relation to the therapeutic working alliance, client compliance and awareness

OBJECTIVE

To investigate the relationship between working alliance, compliance, awareness and subjective outcome of brain injury rehabilitation. Subjects were 86 patients who were clients in an holistic neuropsychological outpatient rehabilitation programme. They had suffered a traumatic brain injury (n = 27), a cerebrovascular accident (n = 49) or some other neurological insult (n = 10).

MEASURES

The therapeutic alliance, clients' awareness and their compliance were rated four times during the 14-week rehabilitation programme. The therapeutic alliance was rated by both clients and therapist using the Working Alliance Inventory (WAI), awareness and compliance were rated by the therapists. Clients completed the European Brain Injury Questionnaire (EBIQ) at programme start and end. Clients and therapists rated the overall success of their collaboration at programme end.

RESULTS

Clients' experience of a good emotional bond between themselves and therapists in mid-therapy was predictive for the reduction of clients' report of depressive symptoms on the EBIQ depression sub-scale (R = 0.68, n = 43, p < 0.001). Good compliance early in the programme was predictive of changes on the EBIQ. Improvement of awareness was related to the amplification of depressive symptoms (r = -0.27, n = 56, p < 0.05).

CONCLUSIONS

Brain injury rehabilitation should be seen as a dynamic process that develops between clients and therapists. Future research should further investigate the relationship between process and outcome and how the therapeutic process can be optimized.

The relationship between clients’ cognitive functioning and the therapeutic working alliance in post-acute brain injury rehabilitation

OBJECTIVE

To examine the impact of brain-injured patients' cognitive abilities on their working alliance (WA) with their therapist in post-acute rehabilitation.

DESIGN

Cognitive tests were administered to brain-injured individuals at the beginning of post-acute, holistic brain-injury rehabilitation. Clients as well as their primary therapists rated their mutual WA at four time points throughout a 14-week rehabilitation programme. Subjects consisted of 86 clients as well as their primary therapists. Clients had suffered a traumatic brain injury (n = 27), a cerebrovascular accident (n = 49) or another neurological insult (n = 10).

MEASURES

(1) Neuropsychological tests of attention, memory and higher cognitive functions; (2) the Working Alliance Inventory, client and therapist short form.

RESULTS

Overall, the relationships between cognitive tests and WA ratings were weak. The tests of attention, memory and higher cortical functions were differentially related to clients' and therapists' view of their mutual WA at the different stages of their collaborative work.

DISCUSSION AND CONCLUSION

Clients' cognitive profile affects clients' and therapists' view of their WA in different ways. The weakness of the correlations between cognitive tests and WA ratings may indicate that a good WA is achievable also with clients with severe cognitive difficulties.

Validity of the Hospital Anxiety and Depression Scale to assess depression and anxiety following traumatic brain injury as compared with the Structured Clinical Interview for DSM-IV

BACKGROUND

Rating scales are often used in the assessment of depression and anxiety in traumatic brain injury (TBI), but few have been validated for use with this population. Overlap of symptoms between such disorders and TBI may lead to under- or over-diagnosis of depression or anxiety.

METHODS

100 participants with mild to severe TBI, and 87 informants, were interviewed using the SCID-IV (Axis I). The HADS was administered at the same time.

RESULTS

According to the SCID-IV, 34 participants were diagnosed with major depression and 36 with an anxiety disorder. Higher HADS scores were associated with a greater likelihood of depression and anxiety. However, the "clinical" categories of the HADS did not strongly correspond with the clinical diagnoses of depression and anxiety. Compared with SCID diagnoses, the depression subscale of the HADS had a sensitivity of 62% and a specificity of 92%. The anxiety subscale had a sensitivity of 75% and a specificity of 69%. Positive predictive and negative predictive values were calculated.

LIMITATIONS

This study included mostly moderate to severe TBI individuals, recruited from a rehabilitation hospital. Therefore, they may not necessarily be representative of the entire TBI population.

CONCLUSIONS

The HADS was a reliable measure of emotional distress in this TBI sample; however the cut-off scores and categories were not useful in predicting caseness of depression and anxiety. Clinicians should be mindful of the sequelae of TBI that may confound the scores yielded in rating scales and should follow up with a psychiatric interview when diagnosis is unclear.

Psychosocial and emotional outcomes 10 years following traumatic brain injury

OBJECTIVES

To investigate the association of psychosocial outcome 10 years following traumatic brain injury (TBI) with demographic variables, injury severity, current cognitive functioning, emotional state, aggression, alcohol use, and fatigue.

SETTING

Community-based follow-up.

PARTICIPANTS

Fifty-three participants with mild to very severe TBI sustained 10 years previously and significant others.

MEASURES

Sydney Psychosocial Reintegration Scale, Extended Glasgow Outcome Scale, Hospital Anxiety and Depression Scale, NFI Aggression scale, Fatigue Severity Scale, Alcohol Use Disorders Identification Test, neuropsychological tests of attention/processing speed, memory, and executive function.

RESULTS

Psychosocial functioning was lowest in the occupational activity domain and highest in the living skills domains. Variables including education, posttraumatic amnesia duration, numerous cognitive measures, concurrent fatigue, aggression, anxiety, and depression were all significantly associated with psychosocial outcome, although the strength of correlations varied between ratings of participants with TBI and relatives. Posttraumatic amnesia duration was most strongly associated with psychosocial outcome measured by relatives; anxiety, aggression, and depression were the strongest predictors when ratings were assigned by participants with TBI. Self-reported fatigue, depression, and alcohol use were the strongest predictors of aggression.

CONCLUSIONS

It is important to address problems with anxiety, depression, fatigue, and alcohol use as a possible means of improving long-term psychosocial outcome following TBI.

Working alliance and patient compliance in brain injury rehabilitation and their relation to psychosocial outcome

Employment and physical activity at follow up of 98 patients who underwent a holistic neuropsychological outpatient rehabilitation programme were examined in relation to therapeutic process factors. The patients had suffered a traumatic brain injury (n = 26), a cerebrovascular accident (n = 58) or another neurological insult (n = 14). Two staff members, a neuropsychologist and a physiotherapist, retrospectively rated patients' compliance with the therapeutic regime and their working alliances. They completed the ratings separately, but had some degree of common knowledge about the patients. While the compliance ratings were closely associated, working alliance ratings differed between the raters. The working alliance ratings were predictive of employment, but not physical activity. Both compliance ratings predicted physical training, but only the neuropsychologist's compliance rating was associated with follow-up employment. Post-hoc analysis showed that high compliance ratings given by the physiotherapist were also a predictor of employment. Overall, there was a tendency for the neuropsychologist's ratings to be more closely associated with employment than the physiotherapist's ratings. These results indicate that employment and physical activity are differentially predictable from different process measures rated from different professional perspectives.
