Objective and Subjective Burden of Informal Caregivers 4 Years After a Severe Traumatic Brain Injury: Results From the PariS-TBI Study

Long-term burden of informal caregiver 7-years after severe childhood traumatic brain injury in the traumatisme grave de l'Enfant (TGE) study

OBJECTIVE

To investigate reported burden by the Primary Family Caregiver (PFC) 7-years after severe pediatric traumatic brain injury in the TGE (Traumatisme Grave de l'Enfant) longitudinal study.

METHODS

Subjective burden was estimated with the Zarit Burden Inventory (ZBI) in 36 PFC (parents), who rated their own health status (Medical Outcome Study Short Form-12), family functioning and their child's level of care and needs (Pediatric/Adult Care And Needs Scale [PCANS/CANS]). Data collection included: child and PFC sociodemographic characteristics, injury-related factors, 'objective' (e.g. overall level of disability: Glasgow Outcome Scale - Extended, GOS-E/GOS-E-Peds) and 'subjective' outcomes (e.g. participation, behavior, executive functions, quality of life and fatigue).

RESULTS

25% of PFC reported mild-moderate burden, and 19% moderate-severe burden. Higher burden correlated with worse outcomes in all 'subjective' PFC-rated outcomes, and with self-reported participation. The ZBI correlated strongly with CANS/PCANS and GOS-E/GOS-E-Peds. Overall level of disability and PFC-reported executive functioning explained 62% of the ZBI variance. For equal levels of disability, burden was higher when PFC reported a 'negative' picture of their child.

CONCLUSION

Significant PFC-reported burden 7-years post-injury was associated with overall disability and 'subjective' PFC-rated outcomes. Factors influencing parental burden in the long term should be identified and psychological support implemented over time.

Burden of Wilson Disease among patients and care partners in the United States: results from a cross-sectional survey

OBJECTIVE

This study assessed the burden of Wilson Disease (WD) among patients and care partners (WD-CPs) in the US and compared it to a US general population of adults (GPs) and care partners (GP-CPs).

METHODS

This cross-sectional, self-reported survey included patients with WD and WD-CPs aged ≥18 years recruited through the Wilson Disease Association (WDA), while data for GPs and GP-CPs were obtained from the 2022 National Health and Wellness Survey. GPs and GP-CPs were propensity score matched (3:1) with WD patients and WD-CPs for demographics and health characteristics. Bivariate analysis evaluated differences in comorbidity burden and health-related outcomes of the WD cohorts compared to matched GP cohorts.

RESULTS

Thirty-seven patients with WD and 53 WD-CPs completed the survey. Most patients reported some treatment burden (73.3%), experienced sleep problems (60%), and visited a healthcare provider (HCP) in the past 6 months (91.9%). Compared with matched GPs, patients with WD had a significantly higher mortality risk (p < .001) and reported greater rates of chronic liver disease, cirrhosis (both, p < .001), migraines (p = .032), non-alcoholic steatohepatitis (p = .004), sleep problems (p = .009) and HCP visits (p = .002). Most WD-CPs (75.5%) reported high burden of caring (mean ZBI-12 score, 26.5) and more negative impact on esteem than GP-CPs.

CONCLUSION

This study highlights the burden of WD experienced by patients and WD-CPs, with patients experiencing high treatment burden, comorbidity burden and healthcare resource utilization, and WD-CPs experiencing high impact of caring, including impact on employment and self-esteem.

The dual reality of challenging behaviours: Overlapping and distinct perspectives of individuals with TBI and their caregivers

Challenging behaviours significantly impact the lives of people with traumatic brain injury (TBI) and their family caregivers. However, these behaviours are rarely defined from the perspectives of both individuals, a necessary step to developing interventions targeting meaningful goals for individuals and caregivers. This study aimed to (1) explore and confirm the perspective of individuals with TBI living in the community and their family caregivers on behaviours they consider challenging and, (2) identify overlapping or distinct views on challenging behaviours. A qualitative descriptive design was used. Twelve caregivers (8 females; 59.67 ± 11.64 years old) and 14 participants with mild-severe TBI (6 females; 43.21 ± 10.98 years old; time post-injury: 21.71 ± 10.84 years) were interviewed (10 dyads and two triads). Data were analysed using inductive qualitative analysis. Challenging behaviours most frequently reported by all participants were aggressive/impulsive behaviours, inappropriate social behaviours, and behavioural manifestations of cognitive impairments. Overlapping perspectives were identified regarding aggressive behaviours. Distinctions exist as inappropriate social behaviours and cognitive difficulties were mainly reported by caregivers. Our results confirm that perspectives may vary between dyad members. Interventions should include dyad inputs to formulate goals that are significant to the person with TBI and their caregiver.

Parental report of levels of care and needs 7-years after severe childhood traumatic brain injury: Results of the traumatisme grave de l'Enfant (TGE) cohort study

This study investigated parental reports of the level of care and needs 7-years following severe childhood traumatic brain injury (TBI), and the factors associated with this outcome. From the 65 children (0-15 years) consecutively admitted to the Parisian regional TBI reference intensive care unit following severe TBI, included in this prospective longitudinal study, 39 patients [M(SD) age at injury = 7.5 years (4.6) and assessment 15.3(4.4)] were followed 7-years post-injury and matched with a control group composed of typically developing participants (n = 34) matched by age, sex and parental education level. We used the Care and Need Scale (CANS) and its Pediatric version (PCANS) to assess the primary outcome 7-years post-injury. Concurrent measures included overall level of disability, and parent- and/or self-reported questionnaires assessing executive functioning, behavior, quality of life, fatigue, participation and caregivers' burden. The level of care and needs was significantly higher in the TBI group than in the control group, the difference being significant with the CANS only. PCANS scores were extremely variable in the control group. High level of dependency was associated with initial TBI severity (higher coma duration and initial Injury Severity Score), higher levels of behavioral problems, executive function deficits, fatigue, and lower participation levels. Caregivers' burden was strongly associated with the CANS. The CANS provides a simple and reliable measure of the support needed long-term after childhood TBI, in accordance with previous studies. The PCANS scores were not significantly different between the TBI and the control groups, which seems to illustrate the difficulty to assess accurately mild-to-moderate deficits of functional independence/adaptive behavior in children based exclusively on parental reports.

The Role of Neuropsychology in Traumatic Brain Injury: Comprehensive Literature Review

Traumatic brain injury (TBI) is a major public health concern, often leading to significant behavioral and cognitive changes with subsequent impairment in daily functioning and personal interactions. The management of TBI involves a multidisciplinary approach. Neuropsychology has emerged as a critical discipline in assessing, diagnosing, treating, and rehabilitating individuals with TBI. Successful management also requires careful consideration of the patient's cognitive status. Therefore, clinicians must have a comprehensive understanding of the overall clinical picture of the patient at the cognitive and physical level. The primary aim of this research is to explore the role of neuropsychology in TBI management and rehabilitation thoroughly while providing an updated review of the literature. Various neuropsychological assessment tools used to evaluate cognitive functioning in individuals with TBI will be discussed in addition to their validity, reliability, and usefulness in identifying cognitive deficits and developing individualized treatment plans. The findings in this article will have significant implications on the clinical practice of neuropsychology in TBI patients, highlighting the importance of neuropsychological assessment in optimizing the management of this population. The need for increased awareness of neuropsychology among health care professionals, especially in the acute hospital setting, is growing along with the increase in diagnosis of TBI and its complications. Adequate understanding of the complex interplay between cognitive, emotional, and behavioral factors in TBI can inform the development of new interventions and treatment strategies, making it equally as important for patients and their families.

Assessing caregiving experience in COPD: content validity of the Zarit Burden Interview in Canadian and Portuguese caregivers

PURPOSE

Informal caregivers play an important role in chronic disease management but their experience is often neglected. The objective of this study was to explore the content validity of the Zarit Burden Interview (ZBI) in caregivers of individuals with COPD in Canada and Portugal.

MATERIALS AND METHODS

Cognitive debriefing interviews were conducted with informal caregivers of individuals with moderate to very severe COPD. Participants completed the ZBI and verbalised their thinking process to assess the adequacy of the questionnaire's content and instructions. Content validity was assessed using deductive content analysis of interviews and descriptive statistics of questionnaire responses.

RESULTS

Nine caregivers from Canada (age = 67 ± 8 years) and 13 from Portugal (age = 69 ± 7 years) participated. For Canadian caregivers, 3/22 items were not understood, and 8/22 items were not relevant to at least 1/3 of them. For Portuguese caregivers, 1/22 items were not understood, and 20/22 items were not relevant to at least 1/3 of them. The distribution of response choices was approximately symmetrical for 17/22 items in the Canadian sample. The response option "no/never" was selected by at least 75% of Portuguese participants for 18/22 items.

CONCLUSIONS

The instrument was well understood by caregivers of people with COPD, but its relevance is uncertain.IMPLICATIONS FOR REHABILITATIONInformal caregivers provide essential care for people living with disability and chronic disease, but their experience is often neglected.The Zarit Burden Interview assesses caregiver burden but has not been validated in caregivers of people with chronic obstructive pulmonary disease.In its current form, the Zarit Burden Interview does not adequately represent the experience of COPD caregivers.We recommend selecting tools that assess caregiver burden that have been validated in the caregiver population of interest.

Monetary valuation of COVID-19 informal care: caregivers' willingness to pay and willingness to accept

BACKGROUND

Informal care can reduce hospitalization frequency and time, elevate bed turnover, and increase the health systems' capacity. This type of care has shown meaningful value in managing many cases through the COVID-19 pandemic. The present study aimed to identify determinants of monetary valuation of informal care and the burden of this care on the COVID-19 patients' caregivers.

METHODS

Through a cross-sectional phone survey from June to September 2021 in Sanandaj city, the west of Iran, COVID-19 patients and their caregivers (Each Group No. 425) were separately interviewed. A simple probabilistic sampling method was applied. Two questionnaires were developed and used after validation. Monetary valuation of informal caregivers was done using Willingness to pay (WTP) and willingness to accept (WTA). Double hurdle regressions were used to determine related variables to WTP/WTA. R software was used for the data analysis.

RESULTS

The total mean (Standard Deviation) of WTP and WTA were $12.02(28.73), $10.30(15.43) USD. Most respondents put a zero value on informal care by WTA (243(57.18%) and WTP [263 (61.88%)]. Caregivers' Employment, and being spouse/child of the care recipient increased the probability of reporting a positive value for WTP (p-value < 0.0001, p-value = 0.011 respectively) and WTA (p-value = 0.004, p-value < 0.0001 respectively). An increase in the number of caring days decreased the probability of reporting positive WTA (p-value = 0.001) and increased the mean of lnWTP (p-value = 0.044). Perceived difficulty in doing indoor activities and perceived difficulty in doing outdoor activities decreased lnWTA mean (p-value = 0.002) and lnWTP mean (p-value = 0.043) respectively.

CONCLUSIONS

Increasing caregivers' self-efficacy and facilitating their involvement in the caring process could be facilitated through flexible work status, educational programs, and interventions on decreasing their burnout.

Predictors of caregiver burden in caregivers of individuals with traumatic or non-traumatic brain injury: A scoping review

BACKGROUND

Caregivers of individuals with traumatic (TBI) or non-traumatic (nTBI) brain injuries are at risk of significant caregiver burden. Consequently, it is crucial to examine predictors of caregiver burden to enable early identification and intervention.

OBJECTIVE

To examine predictors of caregiver burden in caregivers of individuals with TBI/nTBI.

METHODS

A scoping review was conducted in the bibliographic databases PubMed, EMBASE (Ovid) and APA PsycInfo (EBSCO). Search terms included: 'acquired brain injur*', 'traumatic brain injur*', 'brain injur*', 'non-traumatic brain injur*', or 'stroke*' combined with 'burden', 'caregiver burden', 'perceived burden', or 'caregiver strain'. The search was limited to articles written in English and published in academic journals between 2000 and March 2022. EndNote was used to manage the references and identify duplicates.

RESULTS

Twenty-four studies were included. Care recipient-related predictors of caregiver burden included more severe injuries, functional disabilities (including decreased physical and neuropsychological functioning), and worse mental health. Caregiver-related predictors included more time spent caregiving, worse mental health, and unmet needs. For several predictor variables, evidence was mixed or vague.

CONCLUSION

The results highlight which caregivers are at risk of caregiver burden and point to several areas of potential intervention to prevent caregiver burden. Future research should explore the relationship between characteristics of the caregiver and caregiver burden, including coping style, problem-solving techniques, and personality, as these have been sparsely investigated and are potentially modifiable through intervention. Further research is needed to elucidate if burden can be prevented by interventions targeting caregivers at risk. Addressing these gaps may clarify the link between caregiver burden and predictor variables and assist in development of interventions that may prevent burden.

Multisite randomized feasibility study of Problem-Solving Training for care partners of adults with traumatic brain injury during inpatient rehabilitation

BACKGROUND

Problem-Solving Training (PST) during inpatient rehabilitation could provide care partners the skills needed to manage their life roles after discharge.

OBJECTIVE

Determine the feasibility of PST+ Education versus Education for care partners of adults with traumatic brain injury (TBI) during inpatient rehabilitation.

METHODS

We conducted a multisite randomized feasibility trial across three sites. We present recruitment rates, reasons for refusal to participate, and reasons for non-completion of interventions. We measured client satisfaction, participant engagement, and fidelity for both interventions. We compared change in depressive symptoms and caregiver burden between PST and Education groups.

RESULTS

Though the interventions were generally feasible, recruitment and retention rates were lower than anticipated largely due to the COVID-19 pandemic. Participants who completed >3 sessions were less likely to be employed full-time and more often spouses and co-residing. Length of inpatient rehabilitation stay was correlated with number of sessions completed. We observed potential benefits of PST over Education, specifically for reducing depression symptoms and caregiver burden.

CONCLUSION

High satisfaction, engagement, and fidelity, overall recruitment and retention, and positive change in outcomes suggest that PST is generally feasible and beneficial for care partners of persons with TBI. Adaptations, such as developing a 3-session version of PST, could improve feasibility.

Prediction of Increased Intracranial Pressure in Traumatic Brain Injury Using Quantitative Electroencephalogram in a Porcine Experimental Model

Continuous and non-invasive measurement of intracranial pressure (ICP) in traumatic brain injury (TBI) is important to recognize increased ICP (IICP), which can reduce treatment delays. The purpose of this study was to develop an electroencephalogram (EEG)-based prediction model for IICP in a porcine TBI model. Thirty swine were anaesthetized and underwent IICP by inflating a Foley catheter in the intracranial space. Single-channel EEG data were collected every 6 min in 10 mmHg increments in the ICP from baseline to 50 mmHg. We developed EEG-based models to predict the IICP (equal or over 25 mmHg) using four algorithms: logistic regression (LR), naive Bayes (NB), support vector machine (SVM), and random forest (RF). We assessed the performance of each model based on the accuracy, sensitivity, specificity, and AUC values. The accuracy of each prediction model for IICP was 0.773 for SVM, 0.749 for NB, 0.746 for RF, and 0.706 for LR. The AUC of each model was 0.860 for SVM, 0.824 for NB, 0.802 for RF, and 0.748 for LR. We developed a machine learning prediction model for IICP using single-channel EEG signals in a swine TBI experimental model. The SVM model showed good predictive power with the highest AUC value.

Managing challenging behaviours in adults with traumatic brain injury: A scoping review of technology-based interventions

Challenging behaviours are one of the most serious sequelae after a traumatic brain injury (TBI). These chronic behaviours must be managed to reduce the associated burden for caregivers, and people with TBI. Though technology-based interventions have shown potential for managing challenging behaviours, no review has synthesised evidence of technology aided behaviour management in the TBI population. The objective of this scoping review was to explore what technology-based interventions are being used to manage challenging behaviours in people with TBI. Two independent reviewers analysed 3505 studies conducted between 2000 and 2023. Studies were selected from five databases using search strategies developed in collaboration with a university librarian. Sixteen studies were selected. Most studies used biofeedback and mobile applications, primarily targeting emotional dysregulation. These technologies were tested in a variety of settings. Two interventions involved both people with TBI and their family caregivers. This review found that technology-based interventions have the potential to support behavioural management, though research and technology development is at an early stage. Future research is needed to further develop technology-based interventions that target diverse challenging behaviours, and to document their effectiveness and acceptability for use by people with TBI and their families.

Associations between protective resources and family functioning after traumatic brain injury: A cross-sectional study using a structural equation modeling approach

BACKGROUND

A strength-based approach in the rehabilitation after traumatic brain injury (TBI) is recommended for patients and their families. However, further exploration of the complexity of individual and family factors is needed.

OBJECTIVE

To explore the associations between individual protective resources in patients and family members and the overall family functioning using a strength-based approach.

METHODS

Secondary analysis of data collected at baseline in a randomized controlled trial. Structural equation modeling with two latent constructs and six observed variables was performed. Outcome measures included the Resilience Scale for Adults, the Mental Component Summary (SF-36), the General Self-Efficacy Scale, and the Family Adaptability and Cohesion Evaluation Scale-IV.

RESULTS

Hundred and twenty-two participants (60 patients, 62 family members) with a mean age of 43 years were included at a median of 11 months post-injury. The final model demonstrated a strong covariance (coefficient = 0.61) between the latent Protective construct and Family functioning. Model-fit statistics indicated an acceptable fit to the data.

CONCLUSION

Higher levels of protective resources (resilience, self-efficacy, and mental HRQL) were positively associated with family functioning. These resources should be further assessed in patients and their families, to identify factors that can be strengthened through TBI rehabilitation intervention.

A moderated-mediation analysis of pathways in the association between Veterans’ health and their spouse’s relationship satisfaction: The importance of social support

Introduction

Military personnel and Veterans are at increased risk of mental and physical health conditions, which can impact their families. Spouses often perform a vital role in caring for service members and Veterans facing illness or injury, which can lead to caregiver burden. In turn, this may contribute to relationship issues. Research suggests that ensuring that spouses are well supported can alleviate some of these negative effects. The current study examined whether social support received by spouses of newly released Veterans buffers the impact of Veterans’ health on caregiver burden, subsequently impacting spouses’ relationship satisfaction.

Methods

Data were collected as part of the Canadian Armed Forces Transition and Well-being Survey. The sample included N = 595 spouses of Regular Force Veterans who released in 2016 with at least 2 years of service. We examined Veterans’ mental and physical health and spouses’ caregiver burden, social support, and relationship satisfaction. A moderated mediation model was tested using structural equation modeling.

Results

There was a significant indirect association between Veterans’ health (both physical and mental) and spouses’ relationship satisfaction through caregiver burden. Furthermore, social support moderated the association, as evidenced by a weaker association between Veterans’ health and caregiver burden at low levels (−1SD) of social support compared to high levels (+1SD).

Implications

Findings suggest additional efforts should be made to ensure sufficient support is provided to spouses, especially when they are caring for a service member or Veteran facing illness or injury, to strengthen their families’ well-being.

A thematic analysis of patients' and their informal caregivers' gendered experiences in traumatic brain injury

PURPOSE

Research shows that patients' perceptions of themselves and others, in addition to their understanding of the concept of gender, changes after traumatic brain injury (TBI). Little is known about gendered experiences in TBI and care delivery. This study aims to explore perceptions of gender through life experiences and interactions between adult patients with TBI and their informal caregivers.

MATERIALS AND METHODS

Seven patients with mild and moderate-severe TBI and eight informal caregivers were interviewed. Transcripts were coded and analysed according to Braun and Clarke's thematic analysis. The Consolidated Criteria for Reporting Qualitative Research guidelines were followed in reporting results.

RESULTS

The participants described a transformation of their understanding and experiences of gender following the TBI event. Three themes were identified: (1) Gender designations of "man" and "woman";( 2) Post-injury performativity of gender; and (3) Gender in giving and receiving care.

CONCLUSIONS

The findings emphasize the importance of raising awareness among researchers and practitioners on gender as a transformative process for patients with TBI and informal caregivers after the injury. The diversity of patient-caregiver experiences and critical needs based on gender call for intervention approaches that mitigate gender disparities in giving and receiving care. Implications for RehabilitationHistorically, rehabilitation of persons with traumatic brain injury has targeted physical and cognitive impairments, with little attention to their gendered demands in the lived environment.Gender prevails in the lived experiences of persons with traumatic brain injury, and their informal caregivers, and in giving and receiving quality care.A major challenge for clinicians is identifying harmful gendered roles, norms, and relations and the affective/behavioral problems they produce to alleviate enduring distress and reduce disability.Rehabilitation interventions focusing on flexible and adaptive responses to gendered demands in the lived environment of persons with traumatic brain injury are timely.

Mice Cohabiting With Familiar Conspecific in Chronic Stress Condition Exhibit Methamphetamine-Induced Locomotor Sensitization and Augmented Consolation Behavior

Recognizing and sharing emotions are essential for species survival, but in some cases, living with a conspecific in distress condition may induce negative emotional states through empathy-like processes. Studies have reported that stressors promote psychiatric disorders in both, those who suffer directly and who witness these aversive episodes, principally whether social proximity is involved. However, the mechanisms underlying the harmful outcomes of emotional contagion need more studies, mainly in the drug addiction-related behaviors. Here, we investigated the relevance of familiarity and the effects of cohabitation with a partner submitted to chronic stress in the anxiety-like, locomotor sensitization, and consolation behaviors. Male Swiss mice were housed in pairs during different periods to test the establishment of familiarity and the stress-induced anxiety behavior in the elevated plus maze. Another cohort was housed with a conspecific subjected to repeated restraint stress (1 h/day) for 14 days. During chronic restraint the allogrooming was measured and after the stress period mice were tested in the open field for evaluation of anxiety and locomotor cross-sensitization induced by methamphetamine. We found that familiarity was established after 14 days of cohabitation and the anxiogenic behavior appeared after 14 days of stress. Repeated restraint stress also increased anxiety in the open field test and induced locomotor cross-sensitization in the stressed mice and their cagemates. Cagemates also exhibited an increase in the consolation behavior after stress sessions when compared to control mice. These results indicate that changes in drug abuse-related, consolation, and affective behaviors may be precipitated through emotional contagion in familiar conspecifics.

Evaluation of post-traumatic stress disorder (PTSD) and related comorbidities in clinical studies

Patients with traumatic brain injury (TBI) of varying severities are experiencing adverse outcomes during and after rehabilitation. Besides depression and anxiety, post-traumatic stress disorder (PTSD) is highly encountered in civilian and military populations. As more prospective and retrospective studies - focused on evaluating new or old psychological therapies in inpatient, outpatient, or controlled environments, targeting patients with PTSD with or without a history of TBI - are carried out, researchers are employing various scales to measure PTSD as well as other psychiatric diagnoses or cognitive impairments that might appear following TBI. We aimed to explore the literature published between January 2010 and October 2021 by querying three databases. Our preliminary results showed that several scales - such as the Clinician-Administered PTSD Scale (CAPS), the Posttraumatic Stress Disorder Checklist Military Version (PCL-M) as well as Specific Version (PCL-S), and Civilian Version (PCL-C) - have been frequently used for PTSD diagnosis and symptom severity. However, heterogeneity in the scales used when assessing and evaluating additional psychiatric comorbidities and cognitive impairments are due to the study aim and therapeutic approaches. Therefore, conducting an intervention focusing on post-TBI PTSD patients requires increased attention to patients' medical history in capturing multiple cognitive impairments and affected neuropsychological processes when designing the study and including validated instruments for measuring primary and secondary neuropsychological outcomes.

The prevalence, predictors, associated symptoms, and outcomes of social disinhibition following moderate-to-severe TBI: A scoping review of quantitative evidence

The present study aimed to map existing quantitative evidence of research related to the nature of social disinhibition following moderate-to-severe traumatic brain injury (TBI), with a specific focus on its prevalence, predictors, associated symptoms and outcomes in studies that met minimal methodological criteria. We conducted a scoping review of the literature following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) extension for Scoping Reviews (PRISMA-ScR). Seventeen peer-reviewed articles including 1440 participants met the inclusion criteria and were included in the qualitative synthesis. Results of the study indicate that social disinhibition is a common and significant consequence of moderate-to-severe TBI with its prevalence estimates ranging from 21% to 32%. Inappropriate sexual behavior appears to be more prevalent in men and younger survivors. Rule-breaking/perseverative errors in fluency tests are significantly associated with social disinhibition. The perceived burden of caregivers of people with TBI is a very common outcome. An interesting finding was an association between higher social disinhibition and higher emotional empathy levels. However, similarly to many potential predictors, this was only found in a single study and therefore requires further investigation. Some common methodological flaws are discussed, such as the use of non-probability sampling, lack of sample size justification or not including a control group. Due to the heterogeneity of measures used to assess social disinhibition in the reviewed articles, conducting a meta-analysis was not possible. In conclusion, social disinhibition is a significant consequence of moderate-to-severe TBI, as it impacts both the TBI survivor and their family/caregivers. The present study extends the scope of the prior overview by offering a clearer picture of social disinhibition after surviving moderate-to-severe TBI, as it focuses on studies with strong methodology and validated measures. It also assesses potential predictors other than executive dysfunction, such as demographics and injury characteristics.

Barriers and facilitators linked to discharge destination following inpatient rehabilitation after traumatic brain injury in older adults: a qualitative study

PURPOSE

To identify facilitators and barriers associated with returning home for older adults having received inpatient rehabilitation after traumatic brain injury (TBI).

METHODS

A qualitative design was used. Five older patients with TBI and four family caregivers were interviewed and six healthcare professionals participated in a focus group.

RESULTS

Main facilitators to returning home highlighted by all participants were: (1) Patient's adequate health condition and functional status, (2) Access to health and other services at home, (3) Availability of help from a family caregiver. Conversely, if one of these factors was not met, it represented a barrier. Other facilitators identified were (4) Attachment to one's home, (5) Feeling of commitment toward a loved one, (6) Having the possibility of going through a transitional phase, (7) United front between the patient and the family caregiver towards a return home. Additional barriers to returning home included: (8) Incongruent perspectives, and (9) Unclear knowledge about available health and other services at home.

CONCLUSION

The results of this study could be translated into a practical tool to guide patients, families and professionals in the decision about returning home or exploring an alternative option after inpatient rehabilitation for TBI in older adults.IMPLICATIONS FOR REHABILITATIONWhen orienting an older patient home or to an alternative living environment after a traumatic brain injury (TBI), the perspective of rehabilitation professionals can differ from that of patients and caregivers.Professionals tend to emphasize security, whereas patients and caregivers' focus on the well-being associated with home and on the importance of being with their loved one.Integrating the views, values and wishes of older patients with TBI and their caregivers will support a shared decision-making approach for orientation after rehabilitation.

Healthcare Utilization Following Traumatic Brain Injury in a Large National Sample

OBJECTIVE

To evaluate the impact of traumatic brain injury (TBI) on healthcare utilization (HCU) over a 1-year period in a large national sample of individuals diagnosed with TBI across multiple care settings.

SETTING

Commercial insurance enrollees.

PARTICIPANTS

Individuals with and without TBI, 2008-2014.

DESIGN

Retrospective cohort.

MAIN MEASURES

We compared the change in the 12-month sum of inpatient, outpatient, emergency department (ED), and prescription HCU from pre-TBI to post-TBI to the same change among a non-TBI control group. Most rehabilitation visits were not included. We stratified models by age ≥65 and included the month of TBI in subanalysis.

RESULTS

There were 207 354 individuals in the TBI cohort and 414 708 individuals in the non-TBI cohort. Excluding the month of TBI diagnosis, TBI resulted in a slight increase in outpatient visits (rate ratio [RtR] = 1.05; 95% confidence interval [CI], 1.04-1.06) but decrease in inpatient HCU (RtR = 0.86; 95% CI, 0.84-0.88). Including the month of TBI in the models resulted in increased inpatient (RtR = 1.55; 95% CI, 1.52-1.58) and ED HCU (RtR = 1.37; 95% CI, 1.34-1.40).

CONCLUSION

In this population of individuals who maintained insurance coverage following TBI, results suggest that TBI may have a limited impact on nonrehabilitation HCU at the population level.

Measuring emotional suppression in caregivers of adults with traumatic brain injury

OBJECTIVE

Caregivers of individuals with traumatic brain injury (TBI) often feel pressure to maintain the appearance that they are emotionally well adjusted, despite feelings to the contrary. Because there are currently no measures examining this construct, this article focuses on the development of a new measure that is specific to caregivers of people with TBI.

DESIGN

A total of 533 caregivers of civilians with TBI (n = 218) or service members/veterans (SMVs) with TBI (n = 315) completed 43 emotional suppression items, as well as other patient-reported outcomes and an estimate of the functional ability of the person with TBI.

RESULTS

Exploratory and confirmatory factor analyses supported the retention of 25 items. Graded response model (GRM) analyses and differential item functioning (DIF) studies supported the retention of 21 items in the final measure. Expert review and GRM calibration data were used to develop a 6-item static short form (SF) and program a computer adaptive test (CAT). Internal consistency was excellent for both the CAT and SF (reliabilities ≥ 0.91); 3-week test-retest stability was good (all intraclass correlations ≥ 0.89). Convergent validity was supported by moderate associations between TBI-CareQOL Emotional Suppression and related measures (rs from 0.47 to 0.59); discriminant validity was supported by small correlations between Emotional Suppression and positive aspects of caregiving and physical health (rs from 0.14 to 0.28). Known-groups validity was also supported.

CONCLUSIONS

The new TBI-CareQOL Emotional Suppression CAT and 6-item short form is the first self-report measure of this construct in this population. Our findings suggest this new measure has strong psychometric properties. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Mental Health and Family Functioning in Patients and Their Family Members after Traumatic Brain Injury: A Cross-Sectional Study

Traumatic brain injury (TBI) affects the family as a whole. This study aimed to describe and compare mental health and family functioning in TBI patients and their family members, and to identify individual and family-related factors that were associated with mental health. It was conducted at an urban, specialized, TBI outpatient clinic and included 61 patients with mild to severe TBI and 63 family members. Baseline demographics and injury-related data were collected, and the participants answered standardized, self-reported questionnaires 6-18 months post-injury that assessed mental health; general health; family functioning, communication, and satisfaction; depression and anxiety; self-efficacy; resilience; and condition-specific quality of life. The patients reported significantly worse mental health, depression, resilience, self-efficacy, and general health compared with the family members. Patients and family members had similar perceptions, showing balanced family functioning, high family communication levels, and moderate family satisfaction. Factors significantly associated with mental health in patients and family members were depression, anxiety, and resilience, explaining 56% of the variance (p < 0.001). Family-related factors were not associated with mental health. The disease burden was mainly on the patients; however, the family members also reported emotional distress. Family-targeted interventions across the TBI continuum should be considered.

Caregiver burden in familial caregivers and foreign domestic workers of patients with traumatic brain injury in a multi-ethnic Asian population

OBJECTIVE

The purpose of this study was to investigate the prevalence and risk factors associated with caregiver burden in familial caregivers and foreign domestic workers of patients with severe traumatic brain injury.

METHODS

A total of 77 caregivers were consecutively recruited, who were either familial caregivers or foreign domestic workers. All caregivers were evaluated with the Zarit Burden Index (ZBI), Patient Health Questionnaire-9 (PHQ-9), and General Anxiety Disorder 7-item (GAD-7) scale. Logistic regression analysis was conducted to determine factors associated with caregiver burden.

RESULTS

The majority of participants were familial caregivers (N = 60), of which 70% experienced significant caregiver burden. In this group, 10.0% caregivers had clinically significant depression and 16.7% caregivers who had clinically significant anxiety. On multivariate analysis, factors found to be associated with caregiver burden were Glasgow Outcome Scale Extended (GOSE) of <7, presence of neuropsychiatric complications, and presence of anxiety. There was also a high prevalence of caregiver burden in foreign domestic workers (29.4%).

CONCLUSION

There is a high rate of caregiver burden in both familial caregivers and foreign domestic workers who care for patients with severe traumatic brain injury. Caregivers experiencing stress should also be monitored for the presence of anxiety or depression.

Burden and Preparedness amongst Informal Caregivers of Adults with Moderate to Severe Traumatic Brain Injury

This study examined the patterns of informal (unpaid) caregiving provided to people after moderate to severe traumatic brain injury (TBI), explore the self-reported burden and preparedness for the caregiving role, and identify factors predictive of caregiver burden and preparedness. A cross-sectional cohort design was used. Informal caregivers completed the Demand and Difficulty subscales of the Caregiving Burden Scale; and the Mutuality, Preparedness, and Global Strain subscales of the Family Care Inventory. Chi-square tests and logistic regression were used to examine the relationships between caregiver and care recipient variables and preparedness for caregiving. Twenty-nine informal caregivers who reported data on themselves and people with a moderate to severe TBI were recruited (referred to as a dyad). Most caregivers were female (n = 21, 72%), lived with the care recipient (n = 20, 69%), and reported high levels of burden on both scales. While most caregivers (n = 21, 72%) felt “pretty well” or “very well” prepared for caregiving, they were least prepared to get help or information from the health system, and to deal with the stress of caregiving. No significant relationships or predictors for caregiver burden or preparedness were identified. While caregivers reported the provision of care as both highly difficult and demanding, further research is required to better understand the reasons for the variability in caregiver experience, and ultimately how to best prepare caregivers for this long-term role.

Factors Influencing Burden in Spouse-Caregivers of Patients with Chronic-Acquired Brain Injury

In this cross-sectional study, we assess associated factors of burden in spouse-caregivers of patients with acquired brain injury (ABI) in the chronic phase. 35 spouse-caregivers (71% female, mean age ± SD: 55.7 ± 11.1y) of patients with mild/moderate ABI (29% female, mean age ± SD: 57.5 ± 10.7y), admitted to the intensive rehabilitation unit of the Institute S. Anna (Crotone, Italy) between January 2013 and December 2017, were contacted 2 years postinjury and asked to complete a series of questionnaires. The outcome measure was the Caregiver Burden Inventory (CBI) test, while several demographical and clinical data were considered as predictive factors. Two years after injury, a high level of burden was reported in 34.2% of spouse-caregivers. Stepwise multiple linear regression analyses revealed that caring for a patient with more severe disability (as measured by the Barthel Index scale) and the family life cycle (from the initial phase of engagement to marriage with adult children) explain the vast majority of variance for higher caregiver burden. The functional clinical status and the stages through which a family may pass over time were identified as areas in which the spouse-caregiver of ABI patients experienced high levels of burden in the chronic phase.

Valuing Healthcare Goods and Services: A Systematic Review and Meta-Analysis on the WTA-WTP Disparity

OBJECTIVE

The objective of this systematic review was to review the available evidence on the disparity between willingness to accept (WTA) and willingness to pay (WTP) for healthcare goods and services.

METHODS

A tiered approach consisting of (1) a systematic review, (2) an aggregate data meta-analysis, and (3) an individual participant data meta-analysis was used. MEDLINE, EMBASE, Scopus, Scisearch, and Econlit were searched for articles reporting both WTA and WTP for healthcare goods and services. Individual participant data were requested from the authors of the included studies.

RESULTS

Thirteen papers, reporting WTA and WTP from 19 experiments/subgroups, were included in the review. The WTA/WTP ratios reported in these papers, varied from 0.60 to 4.01, with means of 1.73 (median 1.31) for 15 estimates of the mean and 1.58 (median 1.00) for nine estimates of the median. Individual data obtained from six papers, covering 71.2% of the subjects included in the review, yielded an unadjusted WTA/WTP ratio of 1.86 (95% confidence interval 1.52-2.28) and a WTA/WTP ratio adjusted for age, sex, and income of 1.70 (95% confidence interval 1.42-2.02). Income category and age had a statistically significant effect on the WTA/WTP ratio. The approach to handling zero WTA and WTP values has a considerable impact on the WTA/WTP ratio found.

CONCLUSIONS AND IMPLICATIONS

The results of this study imply that losses in healthcare goods and services are valued differently from gains (ratio > 1), but that the degree of disparity found depends on the method used to obtain the WTA/WTP ratio, including the approach to zero responses. Irrespective of the method used, the ratios found in our meta-analysis are smaller than the ratios found in previous meta-analyses.

Alcohol and drug use disorders in patients with cancer and caregivers: effects on caregiver burden

Background

The estimated prevalence of alcohol use disorders in patients with advanced cancer is reported as 4%–38%. There are limited data regarding alcohol and drug use disorders in caregivers of patients with cancer and the effects on other issues.

Aim

To establish the prevalence of alcohol and drug use disorders in a large cohort of patients with advanced cancer and their caregivers.

To evaluate the relationship between alcohol and drug use disorders and patient symptoms and caregiver burden.

Design

The patient with cancer and caregiver completed the Alcohol Use Disorders Identification Tool, CAGE questionnaire and Drug Abuse Screening Test. The patient completed the Memorial Symptom Assessment Scale–Short Form, and the caregiver completed the Zarit Burden Questionnaire.

Statistical analysis compared cases and non-cases of alcohol and drug use disorders with symptom and burden score.

Setting/participants

Patients with cancer, and their caregivers, were recruited from 11 UK sites, 6 hospices and 5 hospitals.

Results

Five hundred and seven patients and their caregivers were recruited. Twenty-seven patients (5%) and 44 caregivers (9%) screened positively for alcohol use disorders on the Alcohol Use Disorders Identification Tool. Thirty patients (6%), and 16 caregivers (3%), screened positively for drug abuse problems on the Drug Abuse Screening Test.

There was a significantly higher carer burden score in caregivers screening positively for alcohol and drug abuse problems.

Conclusions

The prevalence of alcohol use disorders in patients with cancer and caregivers was lower than reported in previous studies. Caregiver burden scores were significantly higher in carers screening positively for alcohol and drug use disorders.

Family-oriented interventions for adults with acquired brain injury and their families: a scoping review

OBJECTIVE

This scoping review sought to describe the literature on the different types of interventions to support families of patients with acquired brain injuries (ABIs) and their outcomes.

INTRODUCTION

Acquired brain injuries are among the leading causes of disability in adults worldwide and have physical, cognitive or/and behavioral consequences not only for the patient, but also for the family. Several support interventions have been proposed in different contexts at different phases of recovery with various levels of evidence, yet no synthesis is available to date.

INCLUSION CRITERIA

We included studies that focused on family members of patients suffering from ABI. The concept under review included any type of intervention or action oriented to support families of patients with ABI, in any care setting. We included all published qualitative and quantitative designs, including those in the gray literature.

METHODS

A three-step search strategy was performed. Searches were conducted in eight major databases, MEDLINE, PubMed, Embase, CINAHL, PsycINFO, Cochrane, JBI Database of Systematic Reviews and Implementation Reports, Web of Science in April 2017, and seven databases for unpublished studies in November 2017. This review was limited to studies published in English and French since January 2007. Additional studies were searched amongst reference lists of all included articles.

RESULTS

We included 89 studies, 19 secondary studies (systematic reviews n = 13, other type of reviews n = 6) and 70 primary studies (experimental studies n = 20, quasi-experimental studies n = 33, other designs n = 17). Even if heterogeneity was found in the characteristics of the 64 selected interventions, emotional support and education were highlighted as the main core components for family-oriented interventions. Mental health and burden were the two most prevalent outcomes found in this scoping review. Interventions targeted families and patients together in 56% of the cases or families alone.

CONCLUSION

This scoping review provides an actual state of the current evidence available for families of patients with ABI. Extended and heterogeneous literature was found, showing the growing interest for considering ABI as a family issue in recent years. However, the overall level of evidence found indicates that more research is still needed to determine key components to intervene within this specific population.

Lawsuit and Traumatic Brain Injury: The Relationship Between Long-Lasting Sequelae and Financial Compensation in Litigants. Results From the PariS-TBI Study

Purpose: People with traumatic brain injury are frequently involved in a litigation because another person was at fault for causing the accident. A compensation amount will often be settled to compensate the victim for the past, present, future damages and losses suffered. We report descriptive data about the full and final personal compensation amount and investigated its association with patient's outcomes.

Methods: We used a longitudinal prospective study of severe TBI patients injured in 2005–2007 (PariS-TBI). Questions regarding involvement in a litigation were asked concurrently with 4 and 8-year outcomes.

Results: Among 160 participants assessed 4 and/or 8 years post-injury, a total of 67 persons declared being involved in a litigation, among which 38 people reported a compensation amount of a mean €292,653 (standard deviation = 436,334; interquartile 25–50–75 = 37,000–100,000–500,000; minimum = 1,500-maximum = 2,000,000). A higher compensation amount was associated with more severe disability and cognitive impairment in patients, and with more informal care time provided by caregivers. However, no significant association related to patient's gender, age, years of education, motor/balance impairment, return to work status, mood and related to caregiver's subjective burden was found.

Conclusion: Financial compensation was related to victims' long-term severity of impairment, although some extreme cases with severe disability were granted very poor compensation.

The Development of a New Computer Adaptive Test to Evaluate Feelings of Being Trapped in Caregivers of Individuals With Traumatic Brain Injury: TBI-CareQOL Feeling Trapped Item Bank

OBJECTIVE

To develop a new patient-reported outcome measure that captures feelings of being trapped that are commonly experienced by caregivers of individuals with traumatic brain injury (TBI).

DESIGN

Cross-sectional.

SETTING

Three TBI Model Systems rehabilitation hospitals, an academic medical center, and a military medical treatment facility.

PARTICIPANTS

Caregivers (N=560) of civilians with TBI (n=344) and caregivers of service members/veterans with TBI (n=216).

INTERVENTIONS

Not applicable.

OUTCOME MEASURES

Traumatic Brain Injury Caregiver Quality of Life (TBI-CareQOL) Feeling Trapped item bank.

RESULTS

From an initial item pool of 28 items, exploratory and confirmatory factor analyses supported the retention of 16 items. After graded response model (GRM) and differential item functioning analyses were conducted, 15 items were retained in the final measure. GRM calibration data, along with clinical expert input, were used to choose a 6-item, static short form (SF), and the calibration data were used for programming of the TBI-CareQOL Feeling Trapped computer adaptive test (CAT). CAT simulation analyses produced an r=0.99 correlation between CAT scores and the full item bank. Three-week short-form test-retest reliability was very good (r=0.84).

CONCLUSIONS

The new TBI-CareQOL Feeling Trapped item bank was developed to provide a sensitive and efficient examination of the effect that feelings of being trapped, due to the caregiver role, have on health-related quality of life for caregivers of individuals with TBI. Both the CAT and corresponding 6-item SF demonstrate excellent psychometric properties. Future work is needed to establish the responsiveness of this measure to clinical interventions for these caregivers.

Understanding Health-related Quality of Life in Caregivers of Civilians and Service Members/Veterans With Traumatic Brain Injury: Establishing the Reliability and Validity of PROMIS Mental Health Measures

OBJECTIVE

To provide important reliability and validity data to support the use of the Patient-Reported Outcomes Measurement Information System (PROMIS) mental health measures in caregivers of civilians or service members/veterans (SMVs) with traumatic brain injury (TBI).

DESIGN

Patient-reported outcome surveys administered through an electronic data collection platform.

SETTING

Three TBI model systems rehabilitation hospitals, an academic medical center, and a military medical treatment facility.

PARTICIPANTS

Caregivers (N=560) of individuals with a documented TBI (344 civilians and 216 military).

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURES

PROMIS anxiety, depression, and anger item banks.

RESULTS

Internal consistency for all the PROMIS Mental Health item banks was very good (all α>.86) and 3-week test-retest reliability was good to adequate (ranged from .65 to .85). Convergent validity and discriminant validity of the PROMIS measures were also supported. Caregivers of individuals who were low functioning had worse emotional health-related quality of life (HRQOL) (as measured by the 3 PROMIS measures) than caregivers of high-functioning individuals, supporting known groups validity. Finally, levels of distress, as measured by the PROMIS measures, were elevated for those caring for low-functioning individuals in both samples (rates ranged from 26.2% to 43.6% for caregivers of low-functioning individuals).

CONCLUSIONS

Results support the reliability and validity of the PROMIS anxiety, depression, and anger item banks in caregivers of civilians and SMVs with TBI. Ultimately, these measures can be used to provide a standardized assessment of HRQOL because it relates to mental health in these caregivers.

A Detailed Overview of Long-Term Outcomes in Severe Traumatic Brain Injury Eight Years Post-injury

Background and aims: Severe traumatic brain injury is a leading cause of acquired persistent disabilities, and represents an important health and economic burden. However, the determinants of long-term outcome have rarely been systematically studied in a prospective longitudinal study of a homogeneous group of patients suffering exclusively from severe TBI

Methods: Prospective observational study of an inception cohort of adult patients with severe traumatic brain injury in the Parisian area (PariS-TBI). Outcome was assessed with face-to-face interview 8 years after Traumatic Brain Injury, focusing on impairments, activity limitations, and participation restriction.

Results: Five hundred and four patients were included between 2005 and 2007. At 8-year follow-up, 261 patients were deceased, 128 were lost to follow-up, 22 refused to participate, and 86 were finally evaluated. Age, gender, initial injury severity did not significantly differ between evaluated patients and lost to follow-up, but the latter were more frequently students or unemployed. Mean age was 41.9 (SD 13.6), 79% were male, median initial Glasgow Coma Scale Score was 6. The most frequent somatic complaints concerned balance (47.5%), motricity (31%), and headaches (36%), but these were less frequent than cognitive complaints (Memory 71%, Slowness 68%, Concentration 67%). According to the Hospital Anxiety and Depression Scale (HADS), 25 % had a score >8 for anxiety and 23.7% for depression. According to the Extended Glasgow Outcome Scale, 19.8% remained severely disabled, 46.5% moderately disabled, 33.7% had a good recovery. Older age, longer education duration, lower functional status upon intensive care discharge, and more severe 8-year dysexecutive problems were significantly associated with a lower Extended Glasgow Outcome Scale score in multivariable analysis. At 8 years, 48.7% of patients were employed in a productive job. Of those, 38% declared a salary loss since traumatic brain injury. Unemployment was significantly associated with lower 1-year GOSE score and more severe 8-year dysexecutive problems.

Conclusions: These results from an inception cohort study highlight the fact that long-term outcome after severe TBI is determined by a complex combination of injury-related, demographic and neuropsychological factors. Long after the injury, persisting impairments still interfere with social integration, and participation.

Longitudinal Outcomes Among Family Caregivers of Power Mobility Users

OBJECTIVE

To examine the change over 1 year in the burden, wheelchair skills, social support, social participation, and mental health of family caregivers providing assistance to older adult powered wheelchair users.

DESIGN

Longitudinal study.

SETTING

Community.

PARTICIPANTS

Participants (N=35) included family caregivers (mean age ± SD=63.7±10.2y) who provided at least 2 hours of general care per week for a powered wheelchair user.

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURES

The Power Mobility Caregiver Assistive Technology Outcome Measure (frequency of care and subjective burden), the Wheelchair Skills Test Questionnaire for caregivers (wheelchair skills), the Interpersonal Support Evaluation List-6 (social support), the Late-Life Function and Disability Instrument (social participation), the Hospital Anxiety and Depression Scale (mental health). Measures were taken at baseline, 1, 3, 6, and 12 months. Descriptive statistics were calculated, and a linear mixed model was used to assess changes over time in the outcomes.

RESULTS

The results showed that the caregivers helped on average with 3 powered wheelchair-related activities and 10 other caregiving activities. They also experienced moderate subjective burden and social participation and were within the normal range for depression and anxiety. Moreover, those outcomes remained stable over the 1-year study period. However, the wheelchair skills scores showed significant changes over time, as the scores improved during the first 6 months of the study.

CONCLUSION

Given that previous research indicated that subjective burden tends to decline over time among caregivers, the findings of stability in this study may reflect increasing needs among this population of caregivers, who may benefit from additional support and interventions. This would need further consideration.

Sociocultural Factors Influencing Caregiver Appraisals Following Traumatic Brain Injury

OBJECTIVE

To investigate the association of the sociocultural variables race/ethnicity, education, and poverty level to caregivers' positive and negative appraisals following traumatic brain injury.

DESIGN

Survey.

SETTING

Community.

PARTICIPANTS

Caregivers (N=344; 216 white; 69 black; 39 Hispanic) of persons with complicated mild to severe TBI at least 1-year postinjury.

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURES

Modified Caregiver Appraisal Scale (M-CAS); Zarit Burden Interview (ZBI).

RESULTS

Black caregivers reported lower levels of perceived burden on both the M-CAS and the ZBI. Black and Hispanic caregivers reported more traditional caregiver ideology (caregiving as a responsibility) than did whites. Greater poverty was associated with higher burden on the M-CAS, lower caregiver satisfaction, and less mastery. Higher education was associated with higher burden on the ZBI and with lower caregiver mastery.

CONCLUSIONS

Treatment professionals should be culturally sensitive to the different perspectives that caregivers may have based on sociocultural factors. Sociocultural factors should be considered in research investigating caregiver outcomes, including appraisals.

Treatment of social cognition impairments in patients with traumatic brain injury: a critical review

Objective: The aim of this study is to review published research on treatment of social cognition impairments in patients with traumatic brain injury (TBI).Methods: Following the PRISMA guidelines, a PubMed literature search was conducted, followed by a manual search in recently published papers. Main criteria for selection were that patients had sustained a TBI, and that social cognition was the main target of treatment. A total of 16 papers and three reviews were selected and included in the present review.Results: Five studies (including three randomized controlled trials (RCT)) addressed facial affect recognition, one study specifically addressed emotional prosody, two RCTs used a combination of treatment strategies addressing social perception deficits. Six studies, including two RCTs, addressed social communication skills or theory of mind. Finally, two RCTs reported the effectiveness of a more global approach, addressing multiple domains of social cognition, such as emotion perception, social skills training, and theory of mind.Discussion/conclusion: Although there has been much less research on treatment of social cognition in patients with TBI as compared with psychiatric conditions, the findings reported in the present review are encouraging. Further multicenter large-scale RCTs are needed, with special emphasis on the generalization of treatment effects to social skills in everyday life.

The Development of a New Computer Adaptive Test to Evaluate Anxiety in Caregivers of Individuals With Traumatic Brain Injury: TBI-CareQOL Caregiver-Specific Anxiety

OBJECTIVE

To design a new measure of caregiver-specific anxiety for use in caregivers of individuals with traumatic brain injury (TBI), the Traumatic Brain Injury Caregiver Quality of Life (TBI-CareQOL) Caregiver-Specific Anxiety item bank.

DESIGN

Cross-sectional survey study.

SETTING

Three TBI Model Systems rehabilitation hospitals, an academic medical center, and a military medical treatment facility.

PARTICIPANTS

Three hundred forty-four caregivers of civilians with TBI and 216 caregivers of service members/veterans with TBI (N=560).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

TBI-CareQOL Caregiver-Specific Anxiety item bank.

RESULTS

The retention of 40 Caregiver-Specific Anxiety items was supported by exploratory and confirmatory factor analyses. Graded response model (GRM) and differential item functioning analyses supported the retention of 33 items in the final measure. Expert review and GRM calibration data was used to select a 6-item static short form, and GRM calibration data was used to program the TBI-CareQOL Caregiver-Specific Anxiety computer adaptive test (CAT).

CONCLUSIONS

Established, rigorous measurement development standards were used to develop the new TBI-CareQOL Caregiver-Specific Anxiety CAT and corresponding 6-item short form. This measure is the first patient-reported outcome measure designed to assess caregiver-specific anxiety in caregivers of individuals with TBI. The measure exhibits strong psychometric properties.

Understanding Health-Related Quality of Life in Caregivers of Civilians and Service Members/Veterans With Traumatic Brain Injury: Establishing the Reliability and Validity of PROMIS Fatigue and Sleep Disturbance Item Banks

OBJECTIVE

To examine the reliability and validity of Patient-Reported Outcomes Measurement Information System (PROMIS) measures of sleep disturbance and fatigue in traumatic brain injury (TBI) caregivers and to determine the severity of fatigue and sleep disturbance in these caregivers.

DESIGN

Cross-sectional survey data collected through an online data capture platform.

SETTING

A total of 4 rehabilitation hospitals and Walter Reed National Military Medical Center.

PARTICIPANTS

Caregivers (N=560) of civilians (n=344) and service member/veterans (SMVs) (n=216) with TBI.

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURES

PROMIS sleep and fatigue measures administered as both computerized adaptive tests (CATs) and 4-item short forms (SFs).

RESULTS

For both samples, floor and ceiling effects for the PROMIS measures were low (<11%), internal consistency was very good (all α≥0.80), and test-retest reliability was acceptable (all r≥0.70 except for the fatigue CAT in the SMV sample r=0.63). Convergent validity was supported by moderate correlations between the PROMIS and related measures. Discriminant validity was supported by low correlations between PROMIS measures and measures of dissimilar constructs. PROMIS scores indicated significantly worse sleep and fatigue for those caring for someone with high levels versus low levels of impairment.

CONCLUSIONS

Findings support the reliability and validity of the PROMIS CAT and SF measures of sleep disturbance and fatigue in caregivers of civilians and SMVs with TBI.

Late Functional Changes Post-Severe Traumatic Brain Injury Are Related to Community Reentry Support: Results From the PariS-TBI Cohort

OBJECTIVES

To explore late functional changes after a traumatic brain injury and their relation to patients' characteristics and reentry support.

DESIGN

Prospective follow-up of an inception cohort of adults with severe traumatic brain injury recruited in 2005-2007 in the Parisian area, France. One and 4-year assessments were performed by trained neuropsychologists. One-to-4-year change in the Glasgow Outcome Scale-Extended defined 3 groups: "improvement," "stability," and "worsening." Relationships between these groups and patients' characteristics were analyzed.

RESULTS

Among 504 recruited patients and 245 four-year survivors, 93 participated in both evaluations. Overall Glasgow Outcome Scale-Extended improved by 0.4. Forty percent of the sample improved, 44% were stable, and 16% worsened. Being in a more unfavorable group was related to preinjury alcohol abuse and to higher anxiety and depression at 4 years. Attendance to a specialized community reentry unit was related to higher chances of being in the "improvement" group in univariate analyses and after adjustment for age, time to follow command, preinjury alcohol and occupation, and mood disorders (adjusted odds ratio [OR] = 4.6 [1.1-20]).

CONCLUSION

Late functional changes were related to psychosocial variables and to reentry support. The effect of reentry support on late recovery needs to be confirmed by further investigations.

Characteristics and Health Outcomes of Post-9/11 Caregivers of US Service Members and Veterans Following Traumatic Brain Injury

OBJECTIVES

To (a) characterize a sample of post-9/11 caregivers providing help to service members and veterans (SMV) following traumatic brain injury (TBI), (b) examine the level of support provided, and (c) determine caregiver health and well-being outcomes.

SETTING

Military treatment facility.

PARTICIPANTS

Caregivers (N = 278) of SMVs who sustained a mild, moderate, severe, or penetrating TBI (96.0% female; 86.0% spouse/partner; age: M = 38.7 years, SD = 10.4). Participants were divided into 3 groups on the basis of the level of support provided (low, medium, high).

DESIGN

Prospective observational.

MAIN MEASURES

Caregiver Appraisal Scale, SF-36v2 Health Survey, Mayo-Portland Adaptability Inventory-4, Caregiver Questionnaire.

RESULTS

The majority of caregivers were helping an SMV with mild TBI and comorbid posttraumatic stress disorder/depression, who was injured in a blast-related incident during combat. Caregivers helped predominantly with activities of daily living and/or instrumental activities of daily living and spent more than 40 hours per week providing care. High-support caregivers were more likely to be caring for an SMV with comorbid posttraumatic stress disorder, report poor physical and mental health outcomes, and have a negative impact on employment and finances.

CONCLUSIONS

A better understanding of protective factors is required to ensure that burden of care does not exceed the caregiver's health and financial capacity, or undermine the care, well-being, and recovery of the SMV.

Self-awareness four years after severe traumatic brain injury: discordance between the patient’s and relative’s complaints. Results from the PariS-TBI study

Objective:

To evaluate the patient’s awareness of his or her difficulties in the chronic phase of severe traumatic brain injury (TBI) and to determine the factors related to poor awareness.

Design/Setting/Subjects:

This study was part of a larger prospective inception cohort study of patients with severe TBI in the Parisian region (PariS-TBI study).

Intervention/Main measures:

Evaluation was carried out at four years and included the Brain Injury Complaint Questionnaire (BICoQ) completed by the patient and his or her relative as well as the evaluation of impairments, disability and quality of life.

Results:

A total of 90 patient-relative pairs were included. Lack of awareness was measured using the unawareness index that corresponded to the number of discordant results between the patient and relative in the direction of under evaluation of difficulties by the patient. The only significant relationship found with lack of awareness was the subjective burden perceived by the relative (Zarit Burden Inventory) ( r = 0.5; P < 0.00001). There was no significant relationship between lack of awareness and injury severity, pre-injury socio-demographic data, cognitive impairments, mood disorders, functional independence (Barthel index), global disability (Glasgow Outcome Scale), return to work at four years or quality of life (Quality Of Life after Brain Injury scale (QOLIBRI)).

Conclusion:

Lack of awareness four years post severe TBI was not related to the severity of the initial trauma, sociodemographic data, the severity of impairments, limitations of activity and participation, or the patient’s quality of life. However, poor awareness did significantly influence the weight of the burden perceived by the relative.

Employment outcome four years after a severe traumatic brain injury: results of the Paris severe traumatic brain injury study

OBJECTIVE

To describe employment outcome four years after a severe traumatic brain injury by the assessment of individual patients' preinjury sociodemographic data, injury-related and postinjury factors.

DESIGN

A prospective, multicenter inception cohort of 133 adult patients in the Paris area (France) who had received a severe traumatic brain injury were followed up postinjury at one and four years. Sociodemographic data, factors related to injury severity and one-year functional and cognitive outcomes were prospectively collected.

METHODS

The main outcome measure was employment status. Potential predictors of employment status were assessed by univariate and multivariate analysis.

RESULTS

At the four-year follow-up, 38% of patients were in paid employment. The following factors were independent predictors of unemployment: being unemployed or studying before traumatic brain injury, traumatic brain injury severity (i.e., a lower Glasgow Coma Scale score upon admission and a longer stay in intensive care) and a lower one-year Glasgow Outcome Scale-Extended score.

CONCLUSION

This study confirmed the low rate of long-term employment amongst patients after a severe traumatic brain injury. The results illustrated the multiple determinants of employment outcome and suggested that students who had received a traumatic brain injury were particularly likely to be unemployed, thus we propose that they may require specific support to help them find work. Implications for rehabilitation Traumatic brain injury is a leading cause of persistent disablity and can associate cognitive, emotional, physical and sensory impairments, which often result in quality-of-life reduction and job loss. Predictors of post-traumatic brain injury unemployment and job loss remains unclear in the particular population of severe traumatic brain injury patients. The present study highlights the post-traumatic brain injury student population require a close follow-up and vocational rehabilitation. The study suggests that return to work post-severe traumatic brain injury is frequently unstable and workers often experience difficulties that caregivers have to consider.

Negative impact of litigation procedures on patient outcomes four years after severe traumatic brain injury: results from the PariS-traumatic brain injury study

PURPOSE

To analyze the effect of litigation procedures on long-term outcomes in severe traumatic brain injury.

MATERIALS AND METHODS

Prospective observational follow-up of an inception cohort including 504 adults with severe traumatic brain injury recruited in 2005-2007 in the Parisian area, France, with initial, one- and four-year outcomes measures.

RESULTS

Four years after the traumatic brain injury, 147 patients, out of 257 who survived the acute phase, were assessed. Among these patients, 53 patients declared being litigants and 78 nonlitigants (litigation status was unknown in 16 cases). Sociodemographic characteristics, type of injury and initial severity did not differ significantly between litigants and nonlitigants, except for Injury Severity Score (worse in litigants) and the proportion of road traffic accidents (higher in litigants). One- and four-year outcomes were significantly worse in litigants for autonomy, participation, psychiatric and cognitive function but not quality of life (measured with the Glasgow Outcome Scale-Extended, the working activity status, the Brain Injury Community Rehabilitation Outcome, the Hospital Anxiety and Depression scale, the Neurobehavioral Rating Scale-revised and the Quality of Life after Brain Injury, respectively). Multivariate analyses highlighted litigation procedure as an independent significant predictor of lower autonomy, participation and psychiatric function and tended to predict lower cognitive function, but not lower quality of life, after adjustment for pretrauma characteristics, Injury Severity Score, road traffic accidents and work-related accident status.

CONCLUSIONS

Patients with severe traumatic brain injury have a worse prognosis when involved in a litigation procedure and require special attention in clinical practice. Implications for rehabilitation The influence of litigation procedure on health and social outcomes in severe traumatic brain injury is a major issue that entail numerous levels of complexities. A wide range of interactions and factors related to the prolonged process of litigation against a third party may influence recovery. Results from the PariS-Traumatic Brain Injury study suggest that patients with a severe Traumatic Brain Injury who are involved in a litigation procedure within French jurisdiction compensation scheme have a worse prognosis than patients who do not. Health professionals should be aware of the potential adverse effects of litigation procedures on recovery, and provide appropriate interventions and information to patients and families in such cases.
