Intimate partner violence (IPV) affects 1 in 3 women and has intensified during the COVID-19 pandemic. Although most injuries are to the head, face, and neck, leaving survivors vulnerable to sustaining traumatic brain injury (TBI), the intersection of IPV and TBI remains largely unrecognized. This article reports on COVID-19–related effects, barriers, needs, and priorities to health care and support services for women survivors of IPV-TBI. Using a participatory research model, we engaged 30 stakeholders in virtual meetings drawn from an IPV-TBI Knowledge to Practice Network in two virtual meetings. Stakeholders included women survivors, service providers, researchers, and decision makers across the IPV, TBI, and healthcare sectors. Data were gathered through small group breakout sessions facilitated by the research team using semistructured discussion guides. Sessions were recorded, transcribed verbatim, and analyzed using thematic analysis techniques. Stakeholders were given the opportunity to contribute to the analysis and knowledge transfer through member checking activities. Ethics approval was obtained through the University of Toronto. Stakeholders shared that COVID-19 has increased rates and severity of IPV and barriers to services and help-seeking. These effects have been exacerbated by infrastructure difficulties in rural and remote areas, including limited access to services. They noted the need to carefully consider implications of virtual care such as safety, privacy, and usability. Requests from survivors for peer support have increased significantly, indicating a need for more formalized and better-supported peer roles. Stakeholders further noted that an overwhelming lack of awareness of the intersection of IPV-TBI continues. Increasing education and awareness among health care and IPV service providers, survivors, and the public remains a priority. The COVID-19 pandemic has intensified IPV-TBI, increased challenges for women survivors, and accentuated the continued lack of IPV-TBI awareness. Key recommendations for health care and rehabilitation to address this priority are discussed.

Intimate partner violence (IPV) affects up to 1 in 3 women over their lifetime and has intensified during the COVID-19 pandemic. Although most injuries are to the head, face, and neck, the intersection of IPV and brain injury (BI) remains largely unrecognized. This article reports on unexplored COVID-19-related impacts on service providers and women survivors of IPV/BI.To explore the impact of the COVID-19 pandemic on survivors and service providers.Purposeful sampling through the team's national Knowledge-to-Practice (K2P) network and snowball sampling were used to recruit 24 participants across 4 categories: survivors, executive directors/managers of organizations serving survivors, direct service providers, and employer/union representatives.This project used a qualitative, participatory approach using semistructured individual or group interviews. Interviews were conducted via videoconferencing, audio-recorded, and transcribed. Transcripts were thematically analyzed by the research team to identify themes.COVID-19 has increased rates and severity of IPV and barriers to services in terms of both provision and uptake. Three main themes emerged: (1) implications for women survivors of IPV/BI; (2) implications for service delivery and service providers supporting women survivors of IPV/BI; and (3) key priorities. Increased risk, complex challenges to mental health, and the impact on employment were discussed. Adaptability and flexibility of service delivery were identified as significant issues, and increased outreach and adaptation of technology-based services were noted as key priorities.The COVID-19 pandemic has intensified IPV/BI, increased challenges for women survivors and service providers, and accentuated the continued lack of IPV/BI awareness. Recommendations for service delivery and uptake are discussed.

Introduction Evidence of the effect of comorbid spinal cord injury (SCI) on cognitive outcome of persons undergoing rehabilitation following newly diagnosed traumatic brain injury (TBI) is limited. We conducted a population-based study to investigate this effect. Objective Cognitive outcomes in patients with TBI with and without a comorbid SCI were compared in a population-based cohort study. Setting/participants Adult patients diagnosed with TBI were identified and followed for one year through provincial health administrative data; those who entered inpatient rehabilitation were studied. Design A retrospective matched cohort study using the National Rehabilitation Reporting System data of all acute care and freestanding rehabilitation hospitals in Ontario, Canada. Main measures The exposure was a comorbid SCI in patients with diagnosed TBI. Exposed patients were matched to unexposed (TBI-only) on sex, age, injury severity, and income, in a ratio of one to two. Gain differences in the cognitive subscale of the Functional Independence Measure were compared between exposed and unexposed patients using multivariable mixed linear model, controlling for comorbidity propensity score, gains in motor function, and rehabilitation care indicators. Results Over the first year post injury, 12,750 (0.84%) of all TBI patients entered inpatient rehabilitation, of whom 1,359 (10.66%) had a comorbid SCI. A total of 1,195 exposed patients (65.4% male, mean age 50.9 ±20.6 for males and 61.8±21.8 for females) were matched to 2,390 unexposed patients. Controlling for confounding, exposed patients had lower cognitive gain (beta,-0.43; 95% CI [-0.72, -0.15]), for both males (beta -0.39; 95% CI [-0.75, -0.03]) and females (beta, -0.51; 95% CI [-0.97, -0.05]) patients. The adverse effects of comorbid SCI were driven largely by lower gains in problem solving and comprehension. Conclusions Adult patients with TBI and comorbid SCI showed a lower cognitive domain response to inpatient rehabilitation than patients with TBI alone. Identifying patients at risk for worse cognitive outcomes may facilitate development of targeted strategies that improve cognitive outcomes. Level III Retrospective Study.

Purpose: The purpose of this study was to explore rehabilitation clinicians' understanding of how sex and gender facilitate or hinder care provided to patients with traumatic brain injury (TBI).Materials and methods: Sixteen clinicians from various specialities, attending to patients with TBI from a large rehabilitation hospital in Ontario, Canada, were recruited using purposive sampling. Data was collected through semi-structured interviews and thematic analysis was used to identify reoccurring themes.Results: Three themes that facilitate or hinder care of TBI patients were identified: (1) knowledge and evidence; (2) gender and other aspects of recovery; and (3) family caregiving. Lack of education about the topic and inconsistent scientific evidence limited clinicians' attention to sex and gender topics. Social, financial, and cultural characteristics of patients were considered to be more relevant than their sex and gender. The gendered nature of caregiving and its burden on caregivers' health were acknowledged.Conclusions: Currently, attention to topics of sex and gender as they may influence patients' recovery is limited. However, clinicians are willing to be educated on these topics to enhance rehabilitation care. Further research on the gendered nature of interactions between patient, clinician, and family caregiver during recovery is warranted.IMPLICATIONS FOR REHABILITATIONSex and gender matter for patients undergoing recovery for their traumatic brain injury; however, clinical attention to this topic is limited.Based on the clinicians' perceptions, resources that address patients' psychosocial vulnerabilities should be prioritized (e.g., unequal access to care, financial status, cultural diversity etc.).Clinicians highlighted that psychosocial vulnerability and patients' life roles, before and after injury, are sex and gender specific.Guidelines about sex and gender influences in traumatic brain injury rehabilitation have the potential to enhance clinical practice.

This scoping review mapped the current evidence about community-based physical activity (PA) interventions for individuals with moderate-to-severe traumatic brain injury (TBI) and identified the reported health-related outcomes, measurement tools used, and considerations given to sex and gender.Searches were conducted in six academic databases for peer-reviewed articles (MEDLINE, EMBASE, Cochrane CENTRAL, CINAHL, SPORTDiscus, and PEDro). PRISMA Scoping Review guidelines were followed. Two reviewers independently screened articles for inclusion and extracted data for the analysis with a modified Consensus on Exercise Reporting Template (CERT). Health-related outcomes were classified with domains of the International Classification of Function, Disability and Health (ICF).19 studies were identified. Seven PA intervention types were included. CERT scores varied (Identified PA interventions from this review revealed common characteristics that led to improved outcomes. Proposed recommendations aim to improve future research and community practice. There is a pressing need for more sex and gender considerations in PA research after moderate-to-severe TBI.

Objective Non-native English speaking workers with a mild work-related traumatic brain and/or head injury are a vulnerable and underrepresented population in research studies. The researchers present their experiences with recruiting and performing qualitative interviews with non-native English speaking individuals with a work-related mild traumatic brain injury, and provide recommendations on how to better include this vulnerable population in future research studies. This paper presents considerations regarding ethics, recruitment challenges, interview preparation and debriefing, sex & gender and language and cultural issues must be made when working with this vulnerable population. Results The researchers discuss critical issues and provide recommendations in recruiting and engaging with non-native English language workers including ethics, recruitment challenges, interview preparation and debriefing, sex & gender and language, and cultural considerations that must be made when working with this population. The study recommendations advise investigators to spend more time to learn about the non-native English participants in the mild wrTBI context, to be familiar with the vulnerabilities and specific circumstances that these workers experience. By increasing their awareness of the challenging facing this vulnerable population, the intention is to provide better care and treatment options through evidence-based research and practice.

Objective: To compare components of inpatient rehabilitation (IR) for patients with traumatic brain injury (TBI) between Canada and the US facilities. Design: Secondary analysis of the TBI-practice-based evidence dataset. Participants: Patients with TBI who had a higher Functional Independence Measure (FIMTM) cognitive function score (≥21) that were admitted to 1 IR facility in Canada (n = 103) and 9 IR facilities in the US (n = 401). Main measures: demographic and clinical characteristics, type and intensity of activities by discipline, discharge location, FIM-Rasch score, social participation and quality of life. Results: Time from injury to rehabilitation admission was significantly longer in the Canadian cohort and they experienced a longer rehabilitation length of stay (p .8). Patients in Canada received a greater total time of individual therapy and lower intensity of interventions per week from all disciplines. They also showed a higher score at discharge in FIM components, while US patients had better cognitive recovery and community participation long-term post-discharge. Conclusions: This study informs stakeholders of the large variation in service provision for patients who were treated in these two countries. These findings suggest the need for robust analyzes to investigate predictors of short and long-term outcomes considering the variation in health-care delivery. List of abbreviations: TBI: traumatic brain injury, CSI: comprehensive severity index, LoS: length of stay, OT: occupational therapy, PT: physical therapy, SLP: speech language pathology, IR: inpatient rehabilitation.

Objectives To explore the patterns of cognitive and motor recovery at 4 time points from admission to 9 months after discharge from inpatient rehabilitation (IR) and to investigate the association of therapeutic factors and conditions before and after discharge with long-term outcomes. Design Secondary analysis of traumatic brain injury (TBI) and practice-based evidence dataset. Setting IR in Ontario, Canada. Participants Patients with TBI consecutively admitted for IR between 2008 and 2011 who had data available from admission to 9 months after discharge (N=85). Interventions Not applicable. Main Outcome Measure FIM-Rasch cognitive and motor scores at admission, discharge, 3 months after discharge, and 9 months after discharge. Results Cognitive and motor recovery showed similar patterns of improvement with recovery up to 3 months but no significant change from 3 to 9 months. Having fewer postdischarge health conditions was associated with better long-term cognitive scores (95% confidence interval, -13.06 to -1.2) and added 9.9% to the explanatory power of the model. More therapy time in complex occupational therapy activities (95% confidence interval, .02 to .09) and fewer postdischarge health conditions (95% confidence interval, -19.5 to -3.8) were significant predictors of better long-term motor function and added 14.3% and 7.2% to the explanatory power of the model, respectively. Conclusion Results of this study inform health care providers about the influence of the timing of IR on cognitive and motor recovery. In addition, it underlines the importance of making patients and families aware of residual health conditions following discharge from IR.

IntroductionWorkplace violence carries a substantial economic loss burden. Up to 10% of all traumatic brain injury (TBI) admissions result from physical assault. There remains a paucity of research on assault as a mechanism of injury, taking into account sex, and its association with work re-entry.ObjectivesThe aim of this study was to characterise, by sex, the sample of workers who had sustained a work-related mild TBI (wr-mTBI) and to assess the independent influence of assault, as a mechanism of injury, on time away from work.MethodsA population-based retrospective cohort of workers’ compensation claimants in Australia (n=3129) who had sustained a wr-mTBI was used for this study. A multivariable logistic regression analysis assessed whether workers who had sustained wr-mTBI as a result of assault (wr-mTBI-assault) were more likely to claim time off work compared with workers who had sustained a wr-mTBI due to other mechanisms.ResultsAmong claimants who sustained a wr-mTBI, 9% were as a result of assault. The distribution of demographic and vocational variables differed between the wr-mTBI-assault, and not due to assault, both in the full sample, and separately for men and women. After controlling for potential confounding factors, workers who sustained wr-mTBI-assault, compared with other mechanisms, were more likely to take days off work (OR 2.14, 95% CI 1.53 to 2.99) within a 3-month timeframe.ConclusionThe results have policy-related implications. Sex-specific and workplace-specific prevention strategies need to be considered and provisions to support return-to-work and well-being within this vulnerable cohort should be examined.

Background: Traumatic brain injury is a neurological disorder of biopsychosocial nature influenced by sex and gender interactions across the lifespan. Traumatic brain injury sustained during adolescence can result in cognitive and social communication impairments that compromise the development and maintenance of intimate social relationships. This can increase both short and long-term vulnerability to poor mental health, social isolation, lack of meaningful friendships, exploitation, and abuse. Females with traumatic brain injury experience greater loss of confidence and have increased risk of victimization, sexual abuse, and violence. This paper aims to provide a framework to inform gender specific rehabilitation of social communication and intimacy, to enhance positive social outcomes for girls and women with Traumatic Brain Injury.Methods: The framework is developed through presentation of a conceptual, multi-dimensional model of intimacy and discussion of current evidence regarding trauma-related cognitive/social-communication impairments and considerations regarding social media.Results: Intimacy is strongly influenced by today's technology-informed "youth culture" and for those with Traumatic Brain Injury, is impacted by cognitive and social communication impairments. Females experience different challenges in recovery and experience of intimacy. There is a need to support girls and women with Traumatic Brain Injury as they develop intimate relationships.Conclusions: This framework can guide the development of female gender-specific rehabilitation and inform future research to promote positive social outcomes.Implications for rehabilitationIntimate relationships are a critical component of mental health and an important part of human development; however, the challenges faced by adolescent girls and woman with TBI in developing and maintaining intimate relationships are often overlooked in traditional rehabilitation programs.A multi-dimensional model of intimacy will help rehabilitation professionals understand the complexities of interventions needed to support healthy intimacy, as well as for harm prevention.Rehabilitation professionals play an important role in advocating for gender-specific supports and interventions.There is a need for early interventions, grounded in today's technological and social media culture, that will support healthy intimacy for adolescent girls and women with TBI.

Background: The cervical spine region can be especially vulnerable to concurrent injury in concussion, with research suggesting that females may be at greater risk due to their weaker and anatomically distinct necks. The main objective of our research was to study sex differences in the rate of neck injury comorbidity across the life span among patients with a concussion diagnosis in the emergency department (ED) setting, by cause of injury (motor vehicle collisions [MVC] and sports). Materials and Methods: All patients with a first concussion-related ED visit between fiscal years 2002/2003 and 2011/2012 (inclusive) in Ontario were identified in population-based health administrative data using the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Canada (ICD-10-CA) codes. Age-dependent odds ratios of comorbid neck injury for sex were estimated using polynomial multivariable logistic regression models, adjusting for sociodemographic characteristics. Results: Females with a concussion had significantly higher odds of sustaining a comorbid neck injury between the ages of 5–49 years for all concussion-related ED visits, 15–49 years for MVC-related concussion ED visits, and 10–39 years for sports-related concussion ED visits, holding all other covariates in the model constant. Conclusions: These results support the consideration of increased screening for comorbid neck injuries, particularly for females, to allow for early intervention. Furthermore, the increased risk of comorbid neck injury in females with a concussion-related ED visit was age-dependent, with the interaction between sex and age following a nonlinear trend. As such, future studies on concussions should consider linear and nonlinear sex and age interactions.

This study identified the social determinants of health (SDoH) associated with psychological distress in adults with and without a self-reported history of traumatic brain injury (TBI), stratified by sex. Data from the 2014–2017 cycles of the Centre for Addiction and Mental Health Monitor Survey, a representative survey of adults ≥18 years in Ontario, Canada, were analyzed (N = 7,214). The six-item version of the Kessler Psychological Distress Scale was used to determine moderate to severe psychological distress. Self-reported lifetime TBI was defined as a head injury resulting in a loss of consciousness for ≥5 minutes or at least one-night stay in the hospital (16.4%). Among individuals reporting a history of TBI, 30.2% of males and 40.1% of females reported psychological distress (p = 0.0109). Among individuals who did not report a history of TBI, 17.9% of males and 23.5% of females reported psychological distress (p

In this report, we identify existing issues and challenges related to research on traumatic brain injury (TBI) in females and provide future directions for research. In 2017, the National Institutes of Health, in partnership with the Center for Neuroscience and Regenerative Medicine and the Defense and Veterans Brain Injury Center, hosted a workshop that focused on the unique challenges facing researchers, clinicians, patients, and other stakeholders regarding TBI in women. The goal of this "Understanding TBI in Women" workshop was to bring together researchers and clinicians to identify knowledge gaps, best practices, and target populations in research on females and/or sex differences within the field of TBI. The workshop, and the current literature, clearly highlighted that females have been underrepresented in TBI studies and clinical trials and have often been excluded (or ovariectomized) in preclinical studies. Such an absence in research on females has led to an incomplete, and perhaps inaccurate, understanding of TBI in females. The presentations and discussions centered on the existing knowledge regarding sex differences in TBI research and how these differences could be incorporated in preclinical and clinical efforts going forward. Now, a little over 2 years later, we summarize the issues and state of the science that emerged from the "Understanding TBI in Women" workshop while incorporating updates where they exist. Overall, despite some progress, there remains an abundance of research focused on males and relatively little explicitly on females.

BACKGROUND: Recent studies have started disentangling components of disturbed sleep as part of the post-concussive syndrome, but little is known about the workers with an injury’ perspectives on post-injury sleep changes or what causes these changes. OBJECTIVES: To determine the effects of work-related concussion/mild traumatic brain injury (wr-mTBI) on perceptions of refreshing sleep in workers with an injury and to identify the relevant factors responsible for sleep changes. METHODS: We studied post-concussive changes in sleep in 66 adults (50% male workers, 42% aged 30–50 years, median post-injury days: 155) who had sustained wr-mTBI and experienced functional limitations long after the injury. We collected sociodemographic, occupational and health status data and identified variables related to post-concussive changes in refreshing sleep. RESULTS: Forty-seven workers with wr-mTBI (79% of male workers, 64% of female workers) perceived their sleep as being refreshing before injury and unrefreshing afterwards (χ2 = 67.70 for change, χ2 = 27.6 for female and χ2 = 41.1 for male workers, p

Concussions are associated with a range of cognitive, neuropsychological and behavioral sequelae that, at times, persist beyond typical recovery times and are referred to as postconcussion syndrome (PCS). There is growing support that concussion can disrupt network-based connectivity post-injury. To date, a significant knowledge gap remains regarding the sex-specific impact of concussion on resting state functional connectivity (rs-FC). The aims of this study were to (1) investigate the injury-based rs-FC differences across three large-scale neural networks and (2) explore the sex-specific impact of injury on network-based connectivity. MRI data was collected from a sample of 80 concussed participants who fulfilled the criteria for postconcussion syndrome and 31 control participants who did not have any history of concussion. Connectivity maps between network nodes and brain regions were used to assess connectivity using the Functional Connectivity (CONN) toolbox. Network based statistics showed that concussed participants were significantly different from healthy controls across both salience and fronto-parietal network nodes. More specifically, distinct subnetwork components were identified in the concussed sample, with hyperconnected frontal nodes and hypoconnected posterior nodes across both the salience and fronto-parietal networks, when compared to the healthy controls. Node-to-region analyses showed sex-specific differences across association cortices, however, driven by distinct networks. Sex-specific network-based alterations in rs-FC post concussion need to be examined to better understand the underlying mechanisms and associations to clinical outcomes.

Objective To identify determinants of discharge disposition from acute care among survivors of hypoxic-ischemic brain injury (HIBI), stratified by sex. Design Population-based retrospective cohort study using provincial data in Ontario, Canada. The determinants were grouped into predisposing, need, and enabling factors using the Anderson Behavioral Model. Setting Acute care. Participants Survivors of HIBI aged ≥20 years at the time of hospitalization and discharged alive from acute care between April 1, 2002, and March 31, 2017. There were 7492 patients with HIBI, of whom 28% (N=2077) survived their acute care episode. Interventions Not applicable. Main Outcome Measures Discharge disposition from acute care, categorized as complex continuing care (CCC), long-term care (LTC), inpatient rehabilitation (IR), home with support, home without support, and transferred to another acute care. Results The discharge dispositions for the 2077 survivors were IR 23.4% (n=487), CCC 19.5% (n=404), LTC 6.2% (n=128), home without support 31.2% (n=647), home with support 15.1% (n=314), and other 4.6%. Multinomial multivariable logistic regression analysis using home without support as the reference category revealed that female patients were significantly more likely than male patients to be discharged to LTC/CCC. Those who were older, were frail, and had longer stay in acute care or special care unit (SCU) were more likely to be discharged to LTC/CCC. The only significant determinant for IR was longer stay in acute care. Survivors with cardiac-related injury were less likely to be discharged to LTC/CCC. Income was a significant factor for male patients but not for female patients in the sex-stratified analysis. The following variables were investigated but were not significant determinants in this study: need factors (comorbidity score, prior psychiatric disorders, health care utilization) and enabling factors (income quintile, rural area of residence). Conclusions Predisposing (age, sex) and need factors (frailty, acute care days, SCU days, type of injury) were significant determinants of discharge disposition from acute care after HIBI. In spite of a system with universal coverage, sex differences were found, with more female patients being discharged to CCC/LTC rather than IR, controlling for age and other confounders. These findings should be considered in appropriate discharge planning from acute care for survivors of HIBI.

Traumatic Brain Injury (TBI) is a serious hidden health issue disproportionately affecting people who experience incarceration.We examined the association between TBI and serious disciplinary charges among men and women sentenced by the courts to terms of two or more years.The study originated in Ontario, Canada and used linked administrative health and correctional data. The cohort included adults experiencing their first federal sentence between 1998 and 2011 (N = 12,038). We examined disciplinary charges incurred 2 years post-sentence commencement. TBI was defined using the International Classification of Diseases (ICD-9 and ICD-10) diagnostic codes. Robust Poisson regression was conducted to assess the association between TBI and disciplinary charges.The prevalence of TBI for the full sample was 13.2%. One-third of adults with a recent TBI had a serious disciplinary charge. The unadjusted risk of incurring a serious charge for those with a history of TBI was 39% higher than those with no history of TBI (CI: 1.29-1.49). The adjusted risk was 1.14 (CI: 1.06-1.22).TBI is a serious health concern that makes it difficult for incarcerants to adjust to prison. Additional support/resources are needed to support those with histories of TBI.

Objective and background Sleep stage disruption in persons with mild traumatic brain injury (mTBI) has received little research attention. We examined deviations in sleep stage distribution in persons with mTBI relative to population age- and sex-specific normative data and the relationships between such deviations and brain injury-related, medical/psychiatric, and extrinsic factors. Patients and methods We conducted a cross-sectional polysomnographic investigation in 40 participants diagnosed with mTBI (mean age 47.54 ± 11.30 years; 56% males). Measurements At the time of investigation, participants underwent comprehensive clinical and neuroimaging examinations and one full-night polysomnographic study. We used the 2012 American Academy of Sleep Medicine recommendations for recording, scoring, and summarizing sleep stages. We compared participants' sleep stage data with normative data stratified by age and sex to yield z -scores for deviations from available population norms and then employed stepwise multiple regression analyses to determine the factors associated with the identified significant deviations. Results In patients with mTBI, the mean duration of nocturnal wakefulness was higher and consolidated sleep stage N2 and REM were lower than normal ( p p = 0.018, and p = 0.010, respectively). In multivariate regression analysis, several covariates accounted for the variance in the relative changes in sleep stage duration. No sex differences were observed in the mean proportion of non-REM or REM sleep. Conclusions We observed longer relative nocturnal wakefulness and shorter relative N2 and REM sleep in patients with mTBI, and these outcomes were associated with potentially modifiable variables. Addressing disruptions in sleep architecture in patients with mTBI could improve their health status.

This paper presents highlights from a program of research addressing sex and gender among persons with traumatic brain injury (TBI) relevant to the Canadian context. Epidemiological trends based on health administrative data are examined, and their implications for policy and practice are considered. Further, the authors discuss the need to proactively address TBI in marginalized populations and in the workplace, two areas that have not received widespread attention.

An increasing number of patients are able to survive traumatic brain injuries (TBIs) with advanced resuscitation. However, the role of their pre-injury health status in mortality in the following years is not known. Here, we followed 77,088 consecutive patients (59% male) who survived the TBI event in Ontario, Canada for more than a decade, and examined the relationships between their pre-injury health status and mortality rates in excess to the expected mortality calculated using sex- and age-specific life tables. There were 5792 deaths over the studied period, 3163 (6.95%) deaths in male and 2629 (8.33%) in female patients. The average excess mortality rate over the follow-up period of 14 years was 1.81 (95% confidence interval = 1.76–1.86). Analyses of follow-up time windows showed different patterns for the average excess rate of mortality following TBI, with the greatest rates observed in year one after injury. Among identified pre-injury comorbidity factors, 33 were associated with excess mortality rates. These rates were comparable between sexes. Additional analyses in the validation dataset confirmed that these findings were unlikely a result of TBI misclassification or unmeasured confounding. Thus, detection and subsequent management of pre-injury health status should be an integral component of any strategy to reduce excess mortality in TBI patients. The complexity of pre-injury comorbidity calls for integration of multidisciplinary health services to meet TBI patients' needs and prevent adverse outcomes.

Aim: This research aimed to gain an understanding of biological sex and social gender phenomena experienced by patients with traumatic brain injury in recovery, and to understand the educational needs of this group.Methods: We conducted semi-structured interviews of 40 adult patients (22 men, 18 women) of different ages, education levels, and ethnicities, with diagnoses of mild and moderate-severe traumatic brain injury at the acute and chronic stages post-injury.Results: Applying classic content analysis with inductive coding, three overarching themes that limited patients' knowledge and subsequent efforts to obtain information on the topic emerged: (1) the complexity of sex and gender subject matters, (2) patients' dependence on others, and (3) uncertainty about the course of recovery. The first diminished the patient's desire to seek further information. Dependence on others and trust that others were in a better position to use the information, compelled patients to redirect the need for education to clinicians, significant others, and the public on the unique post-injury experiences of men and women. Uncertainty about what to expect in the acute phases, and a feeling of identity loss in the chronic phases, established patients' desire to seek out only the information they believed to be necessary for them to carry on with life.Conclusions: In developing recommendations for patient education, variations in patients' knowledge and desire for information, and the reasons behind these variations, should be considered. Improving injury prognosis requires taking into account the gendered context of injury and recovery from it.IMPLICATIONS FOR REHABILITATIONSex/gender issues in traumatic brain injury are complex; the challenge is identifying which information is most relevant for patients; this research assessed patients' knowledge of and interest in sex/gender-related topics in traumatic brain injury.Evidence shows most patients unable to differentiate between sex and gender, but when asked about living as a man or woman with traumatic brain injury, disturbed gender roles and identities became evident.Gender shapes the health status trajectory and outcomes of patients with traumatic brain injury which becomes evident when attention is paid to patients' personal life stories.To improve traumatic brain injury prognosis, clinicians should tailor management plans taking into account gender, an amalgamation of biological, behavioural, cultural, and social characteristics of their patients.In research, explicit and consistent consideration of the interrelated constructs of sex and gender would produce a better understanding of the different mechanisms that shape the course of traumatic brain injury.

Objectives To understand how health status preceding traumatic brain injury (TBI) affects relative functional gain after inpatient rehabilitation using a data mining approach. Design Population-based, sex-stratified, retrospective cohort study using health administrative data from Ontario, Canada (39% of the Canadian population). Setting Inpatient rehabilitation. Participants Patients 14 years or older (N=5802; 63.4% male) admitted to inpatient rehabilitation within 1 year of a TBI-related acute care discharge between April 1, 2008, and March 31, 2015. Interventions Not applicable. Main Outcome Measures Relative functional gain (RFG) in percentage, calculated as ([discharge FIM−admission FIM]/[126−admission FIM]×100). Health status prior to TBI was identified and internally validated using a data mining approach that categorized all International Classification of Diseases, 10th revision, codes for each patient. Results The average RFG was 52.8%±27.6% among male patients and 51.6%±27.1% among female patients. Sex-specific Bonferroni adjusted multivariable linear regressions identified 10 factors of preinjury health status related to neurology, emergency medicine, cardiology, psychiatry, geriatrics, and gastroenterology that were significantly associated with reduced RFG in FIM for male patients. Only 1 preinjury health status category, geriatrics, was significantly associated with RFG in female patients. Conclusions Comorbid health conditions present up to 5 years preceding the TBI event were significantly associated with RFG. These findings should be considered when planning and executing interventions to maximize functional gain and to support an interdisciplinary approach. Best practices guidelines and clinical interventions for older male and female patients with TBI should be developed given the increasingly aging population with TBI.

Objectives: The objective of this scoping review is to examine the extent, range, and nature of literature targeting health-care professionals on the prevalence and outcome of intimate partner violence (IPV)-related traumatic brain injury (TBI). The purpose is to gain an understanding of prevalence, investigate screening tool use, generate IPV/TBI-specific support recommendations, and identify suggestions for future research. Method: The review was guided by Arksey and O’Malley’s five stages for conducting a scoping review. A comprehensive search of nine databases revealed 1,739 articles. In total, 42 published research papers that focused specifically on TBI secondary to IPV were included in the study. Synthesis: The literature reports inconsistencies in prevalence rates from IPV-related TBI. There are no current standardized screening practices in use, though the literature calls for a specialized tool. Frontline professionals would benefit from education on signs and symptoms of IPV-related TBI. Empirical studies are needed to generate reliable data on prevalence, experience, and needs of brain-injured survivors of TBI. Conclusions: Findings from this study demonstrate the need for the development of an IPV-sensitive screening tool, more accurate data on prevalence, an interprofessional approach to care, and raised awareness and education on the diffuse symptoms of IPV-related TBI.

OBJECTIVES: Assault by strangulation has the potential for severe brain injury or death. The objectives of this study were to describe the profile of individuals who had strangulation-related emergency department (ED) or acute care visits, and to explore 1-year readmission outcomes among survivors. METHODS: A population-based retrospective cohort study was conducted using health administrative data in Ontario, Canada. Adults aged 15 years and older who were seen in the ED or acute care with assault by strangulation between fiscal years 2002/2003 and 2016/2017 were included in the study. Bivariate analyses were conducted to compare the patient profile and subsequent readmissions within 1 year of discharge, stratified by sex. RESULTS: A total of 586 patients were included in the study. The majority of these patients were seen in the ED (93%), predominantly female (70%), aged ≤ 39 years (68%), and of lower income quintiles of ≤ 3 (73%). Of the 579 patients who survived the initial admission, 52% had subsequent ED readmission and 21% had acute care readmission within 1 year. In sex-stratified analyses, a higher proportion of females were between 20 to 39 years (58.7% vs. 44.1%, p = 0.001), discharged home (88% vs. 81%, p

Background: Traumatic brain injury (TBI) as a result of intimate partner violence (IPV) is a significant health concern; yet, little is known about the intersection between the two. Existing research is scarce, limiting the ability of health care providers to develop effective supports. This pilot project surveyed the IPV support community in Toronto, Canada to understand the degree of existing TBI-specific knowledge and relevant services available among these service providers and to seek to bridge the divide between research and practice by developing a national knowledge-to-practice network to support brain-injured women survivors of IPV. Materials and Methods: In phase 1, 68 agencies providing IPV support services were invited to complete an anonymous online survey. In phase 2, 22 stakeholders attended a workshop held to disseminate existing knowledge, develop a national knowledge-to-practice network, and determine next steps in research and practice. Results: The results highlighted a general lack of TBI awareness and understanding among IPV service providers. In addition, participants stated that frontline workers and women survivors of IPV alike do not recognize signs or symptoms of TBI. Recommendations addressing research gaps, professional and public education, and service development were identified and are discussed herein. Conclusions: The identified lack of TBI knowledge among IPV service providers highlights the immediate need to increase education among management and frontline workers. Further investigation identifying best practices for knowledge transfer are suggested. The development of a national strategy addressing education, research, and funding is critical for successful uptake and integration of TBI-sensitive services within the IPV sector.

IntroductionThe initiation and translation of sex-sensitive and gender-sensitive research programmes into clinically useful considerations for patients with traumatic brain injury (TBI) have been difficult. Clinical frameworks are currently not specific according to sex and gender, despite evidence that these constructs influence the incidence, course and outcome of patients with TBI. The present protocol outlines a strategy for a research programme, supported by the Canadian Institutes of Health Research (CIHR) Institute of Gender and Health, which explores sex and gender topics in the context of TBI, with the goal of building an infrastructure to facilitate the implementation of sex/gender-sensitive research findings into clinical considerations.Methods and analysisA comprehensive multistep research programme is proposed to support three research objectives: (1) documentation of important concepts and ideas for education on topics of sex and gender in the TBI context using a knowledge-user feedback framework, current scientific evidence and the research team’s expertise; (2) development of educational materials for patients with TBI, significant others and clinicians providing care that account for sex/gender and (3) testing the application of these educational materials for feasibility and effectiveness. This programme supports the CIHR Institute’s mission by facilitating partnership with knowledge users across clinical, research, academic and community sectors, through a range of platforms and activities.Ethics and disseminationThe Research Ethics Board of the University Health Network has approved the programme. It is anticipated that this work will add significant value to the advancement of the field of sex, gender and health by serving as a model to foster the integration of these constructs across the spectrum of disorders. This will transform clinical practices and ensure that generated knowledge is translated into improved training programmes, policies and health services that are responsive to the diverse needs of men and women with TBI.PROSPERO registration numberCRD42018098697

BACKGROUND: Electrical injuries are a common cause of work-related injury in male dominated skilled trades. OBJECTIVES: In this study we explored how issues of gender, masculinities and institutional workplace practices shape expectations of men and their choices when returning to work following a workplace electrical injury. METHODS: Twelve workers, who suffered an electrical injury, and twelve employer representatives, completed semi-structured interviews. Using thematic analysis we identified key themes related to how masculinities influenced men's health and safety during the return to work process. RESULTS: Strong identification with worker roles can influence injured workers decisions to return to work 'too early'. A desire to be viewed as a strong, responsible, resilient worker may intersect with concerns about job loss, to influence participants' decisions to not report safety issues and workplace accidents, to not disclose post-injury work challenges, and to not request workplace supports. Institutionalized workplace beliefs regarding risk, de-legitimization of the severity of injuries, and the valorization of the "tough" worker can further re-enforce dominant masculine norms and influence return to work processes and health and safety practices. CONCLUSIONS: Workplaces are key sites where gender identities are constructed, affirmed and institutionalized. Further research is warranted to examine how established masculine norms and gendered workplace expectations can influence workplace health and safety in male dominated high risk occupations. Future research should also evaluate strategies that encourage men to discuss post-injury work challenges and request supports when work performance or health and safety issues arise during the return to work process.

OBJECTIVES: To examine the etiology, prevalence and severity of physical violence- precipitated work-related traumatic brain injury (wrTBI) in Ontario, Canada. METHODS: Cross-sectional study using data abstracted from the Ontario Workplace Safety and Insurance Board (WSIB) claims files in 2004. Descriptive analyses were conducted to determine the distribution of worker/employment/incident characteristics. RESULTS: Workplace physical violence that resulted in a TBI accounted for 6.6% percent of all TBI injury claims. Female workers, primarily in the health care/social services sector, accounted for over half of all TBIs. Most workers were assaulted by consumers/clients. Forty five percent of injuries occurred among workers with less than 3 years of employment. CONCLUSIONS: This paper identifies profiles of workers and workplaces for targeted preventive efforts. Future studies are needed to further address risk factors by sex and outcomes, such as length of disability and health care cost. Language: en

Symptoms that persist subsequent to a work-related traumatic brain injury (wrTBI) influence the ability to return to work (RTW) and indicate areas of functional disability, as classified in the International Classification of Functioning, Disability and Health (ICF) framework.The purpose of this study was to describe the relationship between RTW status and ICF framework domains in men and women with a wrTBI.A retrospective chart review of 209 consecutive workers with TBI (mild TBI: 71.8%; mean age: 40.2 ± 11.1, men: 71.3%) was conducted. Workers were assessed during the chronic post-injury phase, at the neurology service of a large rehabilitation hospital in Ontario, Canada in 2003. Frequency distributions were calculated and chi-square tests performed.At the point of assessment, 78.0% of workers were in receipt of disability benefits, while the remainder had returned to work on a full- or part-time basis. Significant differences were observed in the Body Functions and Structures domain of the ICF model, specifically clinical diagnoses of depression, anxiety, pain disorders; self-perceived cognitive disturbance, and certain psychosocial factors (p 0.05), between workers who had returned to work and those who had not. When stratified according to sex, these associations remained significant only in men.The factors outlined above should be subject to further TBI research, as indicators for RTW. The lack of significant findings in women warrants further exploration of variables within the physical and social environmental domains of the ICF.

ObjectiveTo understand how pre-injury health status present five-years preceding traumatic brain injury (TBI) affects direct medical cost two years post-injury.MethodsPatients age ≥19 years in the emergency department (ED) or acute care for a TBI between April 1, 2007 and March 31, 2014 in Ontario, Canada (N = 55,669) were identified from population-based health administrative data. Forty-three factors of pre-injury health status (i.e., comorbidities and personal, social, and environmental factors) that were internally validated for the TBI population were assessed in this study. The outcome of interest was direct medical cost within two years of discharge. Sex-specific multivariable linear regressions were conducted to understand the associations between direct medical cost within two years of discharge and pre-injury health status.ResultsPatients who received care in the ED (81.9% of total sample) incurred a median cost of $2,492/male patient (average $12,342/patient) and $3,508/female patient (average $65,285/patient) within two years of injury; 37 pre-injury factors were significantly associated with increased direct medical costs. Patients who first received care for their TBI in acute care (18.1%) incurred a median cost of $25,081/male patient (average $63,060/patient) and $30,277/female patient (average $65,285/patient) within two years of injury; 21 factors were significantly associated with increased direct medical costs. Among more prevalent factors, those associated with increased medical cost by at least 50% included mental health disorders, substance abuse, disorders or medical conditions frequently observed among the elderly, cardiovascular disorders, stroke and emergencies involving the brain, metabolic disorders and abdominal symptoms, conditions and symptoms of abdomen and pelvis, genitourinary disorders and disorders of prostate, and pulmonary abdominal and other emergencies.ConclusionsDirect medical costs two years post-TBI differed significantly between patients with and without adverse pre-existing health status. Interdisciplinary teams to promote early identification of pre-existing health conditions and appropriate management and integration of these conditions in TBI care across the continuum of healthcare may be opportunities to reduce direct medical costs post-injury.

Background Dementia is a major public health concern associated with significant caregiver demands and there are technologies available to assist with caregiving. However, there is a paucity of information on caregiver needs and preferences for these technologies, particularly from a sex and gender perspective. To address this gap in research, the objectives of this study are to examine (1) the knowledge of technology, (2) perceived usefulness of technology, (3) feature preferences when installing and using technology and (4) sex and gender influences on technology needs and preferences among family caregivers of persons with dementia (PWD) across North America. Methods A secondary analysis was conducted on an existing cross-sectional survey with family caregivers of PWDs. Respondents were recruited through the Alzheimer Society of Canada, the Victorian Order of Nurses and Adult Day Programs and other Canadian health care provision institutes. Descriptive statistics, bivariate and multivariate analyses were used to describe the study sample, uncover differences between male and female caregivers and examine sex and gender influences on caregivers’ technology needs and preferences. Results A total of 381 eligible responses were received over a nine month data collection period. The majority of respondents did not know much about and never used any technologies to assist with caregiving. “Being easy to install”, “easy to learn how to use” and “cost” were identified as the most important features when purchasing and setting up technology, while “reliability” was identified as the most important feature when using technology. Most respondents were willing to pay up to $500 to acquire individual technologies. Controlling for other socio-demographic variables, female respondents were more likely to have some or more knowledge about technology for caregiving while male respondents were more willing to pay higher amounts for these technologies compared to their female counterparts. Conclusions As one of the first studies of its kind, our findings represent a step towards the incorporation of sex and gender considerations such as cost and reliability in technology design and promotion for caregivers. Future efforts are warranted to establish an in-depth understanding of sex and gender influences in relation to other social and environmental factors.

Background Although work-related injuries are on the decline, rates of work-related traumatic brain injury (wrTBI) continue to rise. As even mild wrTBI can result in cognitive, behavioural, and functional impairments that can last for months and even years, injury prevention is a primary research focus. Administrative claims data have provided valuable insights into the mechanisms that cause wrTBI; however, data from the perspective of injured workers on wrTBI prevention is limited. Objective Our study aimed to better understand the factors that precipitate wrTBI, as perceived by injured workers. Methods We recruited 101 injured workers from a neurology services clinic with a province-wide catchment area in a large, urban teaching hospital and studied perceived preventability of these injuries from the injured workers' perspective. Results Key findings were that nearly 80% of injuries were perceived as preventable, and nearly 25% and 50% of workers reported that they did not receive job and health and safety training, respectively. Less than half of all workers reported being regularly supervised, and of those who were supervised, approximately two-thirds reported that supervision was adequate. Moreover, 84% and 77% reported they were advised to rest and take time-off after the injury, respectively. Conclusions Our study is the first to show that the vast majority of injured workers consider their wrTBI to be preventable. In addition, we found that training and supervision are two areas that can be targeted by wrTBI prevention strategies. Our study provides valuable and unique perspectives to consider when designing wrTBI prevention initiatives.

Fatigue severity in persons with mild traumatic brain injury (mTBI) has received little research attention, despite its typically positively skewed nature. Investigation of covariates across a range of fatigue severity may provide insight into important contributors.To assess the relative significance of a priori-hypothesized covariates of physiological and pathological (mental and physical) fatigue in persons with mTBI/concussion, applying ordinary least squares (OLS) and quantile regression (QR) approaches.We conducted a cross-sectional investigation in 80 participants with mTBI/concussion (mean age 45.4 ± 10.1 years, 59% male). The fatigue severity scale (FSS) was used as an outcome measure. Predictors of this outcome, grouped into physiological and pathological models of fatigue were assessed using OLS and QR.The mean total FSS score was 46.13 ± 14.59, and the median was 49 (interquartile range 37-57), demonstrating positive skewness. Fatigue severity was associated with variables within the mental, psychological and psychiatric domains at different levels of the fatigue score distribution.Results highlighted that some covariates had a significant impact on the FSS total score at non-central parts of its distribution, while others exhibited significant impact across the entire distribution. Addressing covariates of fatigue across the severity continuum can enhance research and clinical management.

The use of precision medicine is poised to increase in complex injuries such as traumatic brain injury (TBI), whose multifaceted comorbidities and personal circumstances create significant challenges in the domains of surveillance, management, and environmental mapping. Population-wide health administrative data remains a rather unexplored, but accessible data source for identifying clinical associations and environmental patterns that could lead to a better understanding of TBIs. However, the amount of data structured and coded by the International Classification of Disease poses a challenge to its successful interpretation. The emerging field of data mining can be instrumental in helping to meet the daunting challenges faced by the TBI community. The report outlines novel areas for data mining relevant to TBI, and offers insight into how the above approach can be applied to solve pressing healthcare problems. Future work should focus on confirmatory analyses, which subsequently can guide precision medicine and preventive frameworks.

Objective To estimate change in motor, cognitive, and overall functional performance during inpatient rehabilitation (IR) and to identify potential determinants of these outcomes among patients with hypoxic-ischemic brain injury (HIBI). Design Population-based retrospective cohort study using Ontario’s health administrative data. Setting Inpatient rehabilitation. Participants Survivors of HIBI 20 years and older discharged from acute care between fiscal years 2002-2003 and 2010-2011 and admitted to IR within 1 year of acute care discharge (N=159). Interventions Not applicable. Main Outcome Measure Functional status as measured by FIM, total, and scores on motor and cognitive subscales. Results A higher proportion (77%) of HIBI patients in the study were male and 28% were older than 65 years. We observed material improvements in FIM total, motor, and cognitive scores from across the IR episode. Potential determinants of total FIM gain were living in rural location (β, 10.4; 95% CI, 0.21-21), having shorter preceding acute care length of stay (15-30 vs >60 days β, 10.4; 95% CI, 1.4-19.5), and failing to proceed directly to IR following acute care discharge (β, 8.7; 95% CI, 1.8-15.5). Motor FIM gain had similar identified potential determinants. Identified potential determinants of cognitive FIM gain were shorter (ie, 31-60 vs >60 days) preceding acute care, longer IR and length of stay, and proceeding directly to IR. There were no sex differences in functional gain. Conclusions Inpatient rehabilitation is beneficial to HIBI survivors. Timely access to these services may be crucial in achieving optimal outcomes for these patients.

Objectives To (1) assess long-term health care service utilization and satisfaction with health care services among women with traumatic brain injury (W-TBI); (2) examine barriers that prevent W-TBI from receiving care when needed; and (3) understand the perceived supports available for W-TBI. Design Retrospective cohort study. Setting Community. Participants W-TBI (n=105) 5 to 12 years postinjury and women without TBI (n=105) matched on age, education, and geographic location. Interventions Not applicable. Main Outcome Measures Pre- and postinjury data were collected using a questionnaire administered via a semistructured interview. Questions on health services utilization, satisfaction with and quality of services, barriers to receiving care, and perceived social support were from the Canadian Community Health Survey; additional questions on perceived social support were from another large-scale study of people with moderate to severe brain injury. Results Compared with women without TBI, W-TBI reported using more family physician and community health services. W-TBI reported that they did not receive care when needed (40%), particularly for emotional/mental health problems. Significantly more W-TBI reported financial and structural barriers. There were no significant differences in reported satisfaction with services between women with and without TBI. Conclusions Health service providers and policymakers should recognize the long-term health and social needs of W-TBI and address societal factors that result in financial and structural barriers, to ensure access to needed services.

Objective To examine the influence of gender on the return to work experience of workers who sustained a work-related mild traumatic brain injury (TBI). Design Qualitative study using in-depth telephone interviews. Setting Community. Participants Purposive sampling was used to recruit participants. Participants were adults (N=12; males, n=6, females, n=6) with a diagnosis of mild TBI sustained through a workplace injury. Interventions Not applicable. Main Outcome Measures Not applicable. Results Our findings suggest that gender impacts return to work experiences in multiple ways. Occupational and breadwinner roles were significant for both men and women after work-related mild TBI. Women in this study were more proactive than men in seeking and requesting medical and rehabilitation services; however, the workplace culture may contribute to whether and how health issues are discussed. Among our participants, those who worked in supportive, nurturing (eg, feminine) workplaces reported more positive return to work (RTW) experiences than participants employed in traditionally masculine work environments. For all participants, employer and coworker relations were critical elements in RTW outcomes. Conclusions The application of a gender analysis in this preliminary exploratory study revealed that gender is implicated in the RTW process on many levels for men and women alike. Further examination of the work reintegration processes that takes gender into account is necessary for the development of successful policy and practice for RTW after work-related MTBI.

Background. Theatre-based interventions use artistic media to facilitate social and emotional awareness and have therapeutic benefits for persons with developmental disabilities and mental health problems. The role of these interventions with Indigenous youth who have emotional, behavioural, and cognitive sequelae related to fetal alcohol spectrum disorder (FASD) has not been explored. Purpose. The purpose of this study was to explore the experiences and acceptability of a theatre-based approach for facilitating social communication and engagement in youth with FASD. Method. Participants were three Indigenous youth with FASD. A qualitative exploration of the experiences and acceptability of the intervention was conducted via focus groups held 2 weeks post–program participation with the participants, their caregivers, and program facilitators. The transcripts were analyzed using an inductive thematic approach. Findings. Our results identified perceived postintervention improvements in participants’ development of self-esteem, social skills, and emotional awareness. Implications. A theatre-based arts intervention has the potential to support improvements in social skills for youth with FASD.

Background Work-related head injury is a critical public health issue due to its rising prevalence; the association with profound disruption of workers’ lives; and significant economic burdens in terms of medical costs and lost wages. Efforts to understand and prevent these types of injuries have largely been dominated by epidemiological research and safety science, which has focused on identifying risk at the level of the individual worker, population group, or organizational sector. Limited research has focused on the perspectives of the workers, a key stakeholder group for informing understanding of vulnerability to work-related head injury. This study explored workers’ perspectives to better understand their decision-making and how and why their injuries occurred. Methods We conducted a qualitative study using in-depth semi-structured interviews with thirty-two adult workers who had sustained a work-related head injury. Workers were recruited from an urban clinic in central Ontario, Canada. Labour Process Theory informed the thematic analysis. Results Three hazardous work conditions were identified: insufficient training; inadequate staffing; and inattention to the physical environment. In addition, professional and organizational norms were implicated in vulnerability to head injury including putting the client before the worker and the pressure to work unsafely. The findings also highlight a complex interrelationship between workers’ decision-making and professional and organizational norms that produces vulnerability to head injury, a vulnerability which oftentimes is reproduced by workers’ decisions to work despite hazardous conditions. Conclusions Our findings suggest that, beyond the need to redress the inattention to hazards in the physical environment, there is a need to address norms that influence worker decision-making to improve the safety of workers. Using Labour Process Theory highlights an important social dynamic within workplace sectors that could inform future development and implementation of multi-level and integrated public health strategies to reduce work-related head injury.

Objective Comorbid disorders influence the course and outcomes of rehabilitation following traumatic brain injury (TBI), yet sex- and age-related disparities in the frequency distribution of these disorders remain poorly understood. We aimed to describe comorbid disorders by the International Classification of Diseases in patients with TBI undergoing inpatient rehabilitation in Ontario, Canada over a 3-year period, by sex and age, and discuss their potential impact on rehabilitation outcomes. Results The percentage of TBI patients with one or more comorbid disorder is higher among older (≥65 years) men and women than among those who are younger or middle-aged (

BACKGROUND Work-related traumatic brain injury (wrTBI) is the most significant occupational injury associated with death and disability. Few studies have investigated injury text narratives to inform prevention strategies. OBJECTIVE To identify factors leading to wrTBI in male and female workers utilizing the Person-Environment-Occupation (P-E-O) framework. METHODS A retrospective chart review of the medical records of 98 consecutive Ontario workers with a diagnosed wrTBI was performed. Sociodemographic, occupational, injury-related, clinical, and environmental data were collected from medical assessments and insurers' files. A mixed methods approach was employed to analyse the data. RESULTS Five occupational hazard themes emerged from the injury narratives: unexplained person factor, action by co-worker, external environment, safety measures, and equipment malfunction. Male workers were more likely than female workers to experience a wrTBI due to an equipment breakdown or malfunction. Statistically significant sex differences were observed across P-E-O factors. CONCLUSION Efforts directed at identifying and remedying various injury patterns are necessary for the development of brain injury primary prevention recommendations, to reduce the prevalence of these vastly impactful incidents.

In this study, we explored the experiences of 13 individuals who had suffered an electrical injury at work and had subsequently returned to work. In this article, we report on the social, institutional, and relational elements that workers perceived to influence return to work experiences and the provision of workplace accommodations. These elements included (a) worker resources, (b) job characteristics, (c) workplace setting, (d) injury elements, (e) workers’ compensation context, and (f) supports and advocacy provided. We conclude that the availability and provision of supportive accommodations are influenced by a multiplicity of interrelated factors including the legitimacy of resulting impairments following electrical injury, institutional structures (e.g., compensation and health care systems), the social relations of work, and broader labor market and economic contexts. Those workers who were vulnerable because of factors such as employment circumstances or labor market conditions were often poorly supported when returning to work following electrical injury.

The objective of this study was to gain an understanding of workers' experiences with returning to work, the challenges they experienced, and the supports they found most beneficial when returning to work after a workplace electrical injury. Thirteen semistructured qualitative telephone interviews were conducted with individuals who experienced an electrical injury at the workplace. Participants were recruited from specialized burns rehabilitation programs in Ontario, Canada. Interviews were transcribed verbatim and thematic analysis used to analyze the qualitative interviews. Data regarding workers' demographics, injury events, and occupational categories were also gathered to characterize the sample.Participants identified three distinct categories of challenges: 1) physical, cognitive, and psychosocial impairments and their effects on their work performance; 2) feelings of guilt, blame, and responsibility for the injury; and 3) having to return to the workplace or worksite where the injury took place. The most beneficial supports identified by the injured workers included: 1) support from family, friends, and coworkers; and 2) the receipt of rehabilitation services specialized in electrical injury. The most common advice to others after electrical injuries included: 1) avoiding electrical injury; 2) feeling ready to return to work; 3) filing a Workplace Safety and Insurance Board injury/claims report;4) proactive self-advocacy; and 5) garnering the assistance of individuals who understood electrical injuries to advocate on their behalf. Immediate and persistent physical, cognitive, psychosocial, and support factors can affect individuals' abilities to successfully return to work after an electrical injury. Specialized services and advocacy were viewed as beneficial to successful return to work. Language: en

Objective: This study examined factors associated with living setting of patients with acquired brain injury at discharge from inpatient rehabilitation. Design: Retrospective cohort design. Subjects/Patients: Cohort of patients first identified in acute care with a diagnostic code of traumatic or non-traumatic brain injury who also subsequently received inpatient rehabilitation in Ontario, Canada for fiscal years 2003/2004 to 2005/2006. Methods: Using logistic regression, we examined predisposing, need and enabling factors associated with living settings at discharge from inpatient rehabilitation (home/other versus residential care). Acute care and inpatient rehabilitation data were used. Results: The majority of patients (83%) were discharged home after inpatient rehabilitation. Among ABI patients, those with longer lengths of stay and patients living alone and in non-home settings at admission were significantly more likely to be living in a residential care setting at discharge. Conversely, patients with higher total function scores from the FIM TM Instrument and those receiving informal support at discharge were significantly less likely to be living in a residential care setting at discharge. Conclusion: Our findings suggest that informal support influences service utilization and provide evidence for its importance at discharge with respect to living in the community. Prior living arrangement and functional outcome at discharge significantly predicted discharge destination. Improving physical function and providing needed supports at discharge may be factors important to reduce the demand for residential care facilities.

RÉSUMÉCette étude a examiné un profil basé sur la population des personnes âgées atteintes des lésions cérébrales acquises (LCA), et de leur résultats fonctionnels, en réadaptation en milieu hospitalier au Canada. Les personnes âgées de 65 ans et plus qui ont été admises en réadaptation en milieu hospitalier de soins aigus pour un traumatisme cranio-cérébrale (TCC) (n = 1 214) ou une lésion cérébrale non pas traumatique (nTCC) (n = 1 530) ont été identifiées en Ontario de 2003/04 à 2009/10. Les caractéristiques démographiques et cliniques et les notes fonctionnelles totales de l’instrument (FIMMD) ont eté examinées. On a utilisé le Base de données sur les congés des patients (BDCP) et le Système nationale d’information sur la réadaptation (SNIR). Les résultats ont montré que les personnes plus âgées atteintes d’un traumatisme cranio-cérébrale (TCC) présentaient un niveau d’indépendence fonctionelle plus élevé que celles sans TCC à l’admission et à la sortie. Cependant, les deux groupes ont faits des gains importants (p = .001) et similaires (p > .05). Nous concluons que les personnes âgées avec TCC et nTCC font des gains similaires de réadaptation en milieu hospitalier. L’incapacité fonctionnelle initiale plus faible des patients nTCC à l’admission et les profils cliniques différents offrent des implications pour la répartition des soins et des ressources cliniques.

Supplemental Digital Content is available in the text, Pain is an unpleasant, complex, and perceived experience that places a significant burden on patients and clinicians. Its severity may be mediated by emotion, attitude, and environmental influences, and pain may be expressed differently in males and females. Traumatic brain injury (TBI) is frequently associated with chronic pain. This diagnostic modeling study examined sex differences in the construct of chronic pain in patients with delayed recovery from concussion/mild traumatic brain injury (mTBI). Data were collected from standardized questionnaires, neuroimaging records, and comprehensive clinical assessments. Bivariate associations were calculated using the Spearman correlation coefficient or analysis of variance. We established sex-specific stepwise multivariate linear regression models of factors associated with pain. Of the 94 participants diagnosed with mTBI (the mean age was 45.20 ± 9.94 years; 61.2% were males; the median time since injury was 197 days [interquartile range 139–416]), head/neck, and bodily pain were reported by 93% and 64%, respectively. No sex differences were identified in pain frequencies or severity. Pain was significantly associated with certain socio-demographic, injury-related, behavioral, and clinical variables. In the multivariable regression analysis, several determinants explained 60% of the pain variance in males and 46% in females. Pain is common in patients with delayed recovery from mTBI and is significantly associated with potentially modifiable clinical and nonclinical variables. Examining the multidimensional construct of pain in concussion/mTBI through a sex lens garners new directions for future longitudinal research on the pain mechanisms involved in postconcussion syndrome.

To investigate the characteristics and inpatient rehabilitation outcomes of persons who sustained a traumatic brain injury (TBI) resulting from physical assault - a form of intentional TBI - and compare these outcomes to those of persons with TBI resulting from other aetiologies.A prospective population-based cohort study using inpatient rehabilitation data from Canadian population-based administrative databases for the fiscal years 2001-2006. Outcome measures were measures of functional independence (motor and cognitive), as measured by the FIM™ Instrument, and discharge destinations.Characteristics associated with intentional TBI were being male, younger in age and unemployed; living alone and having a greater likelihood of alcohol/drug abuse prior to admission. The intentional TBI group showed poorer total functional gains at discharge from inpatient rehabilitation. Multivariate regression analyses showed that persons with intentional injury were less likely to be discharged home.Persons with TBI from physical assault are a distinct clinical group in Canadian inpatient rehabilitation settings. These findings can support clinicians in determining proper assessment, management, discharge planning and post-rehabilitation care that target specific needs of persons with TBI resulting from physical assault.Clinicians should have appropriate training to properly assess the mental health status of this patient group. Inpatient rehabilitation facilities should be prepared to provide services targeting psychosocial, substance abuse and interpersonal relationship issues to persons with a TBI from physical assault while patients are still within a hospital setting. Follow-up clinical care and community support services are warranted for those with intentional TBIs, including provision of occupational rehabilitation services, such as vocational rehabilitation. The discharge team should be responsible for ensuring appropriate discharge to community in the absence of family or other advocates on behalf of the patient.

Discharges against medical advice (DAMA) have been considered predictors of adverse outcomes for patients in acute care and psychiatric hospitals. However, little is known about the profile of patients who discharge AMA admitted to rehabilitation hospitals. The aims of this study were to provide a profile of patients who received inpatient rehabilitation services following a traumatic brain injury (TBI) who discharged AMA and to compare this group with the regular discharge group.Retrospective cohort study.Hospital discharge data from two national administrative databases were reviewed for the years 2001-2006.The databases yielded 1559 cases of TBI (average length of stay = 51 days). Of these, 31 (2.0%) had recorded DAMA events: one in 50 patients left rehabilitation against medical advice. Compared to regular discharge (n = 1247), DAMA was significantly associated with unemployment, intentional injury, higher motor functions at admission and shorter length of stay. Known factors for DAMA in acute hospitals, such as male sex, young age and substance abuse history, were not significant.Careful screening and assessment of patients who discharge AMA could enable better prevention and management strategies, thus improving health outcomes and enhancing healthcare delivery.

BACKGROUND: Work-related traumatic brain injury (wrTBI) comprises up to 24% of TBIs, yet relatively little is known about it even though wrTBI incurs high costs to employers, insurers, and injured. OBJECTIVES: To compare demographic, clinical, and occupation-related factors following mild-to-moderate TBI of those who successfully returned to work (RTW) versus those who did not, and to determine perceived facilitators of and barriers to RTW. METHODS: Retrospective cohort study from a consecutive sample of persons with TBI seen in an outpatient assessment clinic. Surveys were mailed to eligible potential participants. Consenting participants were interviewed by telephone or returned a completed survey via mail. RESULTS: Fifty of 116 eligible individuals participated in the study. Half of the participants returned to work. Participants in this group were significantly younger and had more years of education than the no-RTW group. The most common factors perceived to assist the RTW group were support of family and friends (92%) and of treatment providers (80%), and employers who provided accommodations (76%). Difficulty thinking and concentrating (94%) and fatigue (94%) were the most common barriers to RTW. CONCLUSIONS: This study highlights the importance of support from family, friends and employers as RTW facilitators. These factors merit further investigation in TBI rehabilitation studies.
