Traumatic brain injury and intimate partner violence: Addressing knowledge and service gaps among indigenous populations in Canada

Barriers to Care After Intimate Partner Violence Acquired Brain Injury: Current Systems Silence Survivors and Providers

OBJECTIVE

A qualitative meta-synthesis was conducted to answer the following question-What barriers are experienced by survivors of intimate partner violence and service providers when seeking or providing resources or care after experiencing brain injury (BI)?

SETTING

This approach was completed through 2 main phases-a systematic search and literature appraisal and reciprocal translation with interpretive triangulation of the extracted data. The databases searched were PubMed, CINAHL, and PsycInfo.

PARTICIPANTS

The initial search yielded 559 articles. The final synthesis included 16 articles for the qualitative meta-synthesis.

DESIGN

After data extraction, a qualitative exploratory design evaluated the experiences of survivors and service providers when connecting with resources.

RESULTS

The findings highlight larger systemic barriers preventing smooth relationships between survivors and providers. Survivor barriers include risk-driven safety mechanisms and a lack of awareness and understanding of BI. Provider barriers are a lack of clarity within providers' scope and training limitations, diagnosis complexity, first responder's initial response to survivors, lack of open discussion, screening limitations, financial barriers, infrastructure barriers, and lack of resources. Systemic barriers include stigmatization, BI symptoms mistaken as other diagnoses like mental health, access and awareness of resources, and navigation of complex systems.

CONCLUSION

This qualitative meta-synthesis demonstrates that survivors and providers face multiple individual and systemic barriers when seeking and providing resources after BI. Future research is needed to understand survivors' help-seeking behaviors and assistance needs and providers' education about BI and organizational relationships and networks. Recommendations are made for future research to understand how to reduce barriers for providers working with survivors, from trauma-informed education and communication to connecting with resources, where to concentrate, and initiatives for collaboration to increase the network of resources yet improve its accessibility.

Best Practices and Methodological Strategies for Addressing Generalizability in Neuropsychological Assessment

Generalizability considerations are widely discussed and a core foundation for understanding when and why treatment effects will replicate across sample demographics. However, guidelines on assessing and reporting generalizability-related factors differ across fields and are inconsistently applied. This paper synthesizes obstacles and best practices to apply recent work on measurement and sample diversity. We present a brief history of how knowledge in psychology has been constructed, with implications for who has been historically prioritized in research. We then review how generalizability remains a contemporary threat to neuropsychological assessment and outline best practices for researchers and clinical neuropsychologists. In doing so, we provide concrete tools to evaluate whether a given assessment is generalizable across populations and assist researchers in effectively testing and reporting treatment differences across sample demographics.

Exploring the intersection of brain injury and mental health in survivors of intimate partner violence: A scoping review

Rationale

Intimate partner violence (IPV) is the most commonly occurring form of violence against women. The most common site of injury in IPV is the head, face, and neck, resulting in possible brain injury (BI). Independently, mental health (MH) concerns are highly prevalent among both IPV survivors and individuals with BI; however, no systematic review exists on the combined experience of BI and MH in IPV.

Objective

The aim of this review was to describe the identification of and relationships between BI, MH, and IPV in the literature and the implications for health policy and practice.

Methods

A search strategy including text words and subject headings related to BI, IPV, and MH was developed for MEDLINE and translated to EMBASE, PsycINFO, CINAHL, Cochrane, Scopus, and Web of Science. Two reviewers independently assessed articles for inclusion. Articles discussing MH, BI, and IPV in relation to one another were included in the review.

Results

Twenty-eight articles were identified for inclusion. Methods for identifying IPV, BI, and MH were highly variable across studies. Fourteen studies reported significantly higher MH scores in IPV survivors with BI than in those without BI. Articles predominantly focused on cis gender women in heterosexual relationships and the impact of race and ethnicity were largely overlooked. Healthcare access was explored by eight articles, though none discussed the implications of co-occurring BI and MH.

Conclusion

Brain injury and MH are highly prevalent among IPV survivors; however, little research discusses the implication for healthcare. Future research should explore healthcare-related needs and experiences to inform policy and practice and better represent the diversity of IPV survivors.

Effects of the Response to the COVID-19 Pandemic on Assault-Related Head Injury in Melbourne: A Retrospective Study

Assault is the leading preventable cause of death, traumatic brain injury (TBI), and associated mental health problems. The COVID-19 pandemic has had a profound impact on patterns of interpersonal violence across the world. In this retrospective cross-sectional study, we analysed medical records of 1232 assault victims (domestic violence: 111, random assault: 900, prison assault: 221) with head injuries who presented to the emergency department (ED) at St Vincent's Hospital in Melbourne, Australia, a city with one of the longest and most severe COVID-19 restrictions worldwide. We examined changes in prevalence in the assault group overall and in domestic violence, random assault, and prison assault victims, comparing data from 19.5 months before and after the first day of COVID-19 restrictions in Melbourne. Moreover, we investigated differences driven by demographic factors (Who: age group, sex, and nationality) and clinical variables (Where: assault location, and When: time of arrival to the ED and time from moment of injury until presentation at ED). Descriptive statistics and chi-square analyses were performed. We found the COVID-19 pandemic significantly affected the Where of assault-related TBI, with a shift in the location of assaults from the street to the home, and the increase at home being driven by random assaults on middle-aged adults. Overall, we observed that 86% of the random assault cases were males, whereas 74% of the domestic assault cases were females. Meanwhile, nearly half (44%) of the random assault victims reported alcohol consumption versus a fifth (20%) of domestic violence victims. These findings will have direct implications for developing screening tools and better preventive and ameliorative interventions to manage the sequelae of assault TBI, particularly in the context of future large-scale health crises or emergencies.

Indigenous Cultural Safety in Recognizing and Responding to Family Violence: A Systematic Scoping Review

This systematic scoping review synthesizes the recommended approaches for providing culturally safe family violence interventions to Indigenous peoples in health care and social service settings. A total of 3783 sources were identified through our electronic database searches, hand-searching of Indigenous-focused journals, and backward and forward citation chaining. After screening those sources in duplicate, 28 papers were included for synthesis in June 2020. Forward citation chaining of these 28 included articles in June 2022 identified an additional 304 possible articles for inclusion; following the screening of those 304 articles, an additional 6 were retained in the review. Thus, a total of 34 articles were included for data extraction and narrative synthesis. Initial results were presented to members of the Six Nations of the Grand River Youth Mental Wellness Committee, and their feedback was incorporated into our inductive organization of findings. Our findings represent three thematic areas that reflect key recommendations for health care and social service provision to Indigenous families for whom family violence is a concern: (1) creating the conditions for cultural safety; (2) healing at the individual and community level; and (3) system-level change. These findings demonstrate the need to center Indigenous peoples and perspectives in the development and implementation of cultural safety approaches, to acknowledge and address historically contingent causes of past and present family violence including colonization and related state policies, and to transform knowledge and power relationships at the provider, organization, and government level.

Shifting paradigm from biomedical to decolonised methods in Inuit public health research in Canada: a scoping review

BACKGROUND

The National Inuit Strategy on Research focuses on advancing Inuit governance in research, increasing ownership over data and building capacity. Responding to this call for Inuit self-determination in research, academic researchers should consider cultural safety in research and ways to promote Inuit-led methods.

METHODS

This scoping review collated academic literature on public health research in Inuit communities in Canada between 2010 and 2022. A critical assessment of methods used in public health research in Inuit communities examined cultural safety and the use of Inuit-attuned methods. Descriptive and analytical data were summarised in tables and figures. Knowledge user engagement in the research process was analysed with thematic analysis.

RESULTS

356 articles met the inclusion criteria. Much of the published research was in nutrition and mental health, and few initiatives reported translation into promotion programmes. Almost all published research was disease or deficit focused and based on a biomedical paradigm, especially in toxicology, maternal health and chronic diseases. Recent years saw an increased number of participatory studies using a decolonial lens and focusing on resilience. While some qualitative research referred to Inuit methodologies and engaged communities in the research process, most quantitative research was not culturally safe. Overall, community engagement remained in early stages of co-designing research protocols and interventions. Discussion on governance and data ownership was limited. Recent years saw emerging discussions on these issues. Knowledge user capacity-building was limited to brief training on conventional data collection methods.

CONCLUSIONS

The last decade of published public health research has not responded to the National Inuit Strategy on Research. Participatory research is gaining ground, but has not reached its full potential. A shift from biomedical to decolonised methods is slowly taking place, and public health researchers who have not yet embraced this paradigm shift should do so.

Neurotrauma in Indigenous Populations of Canada-Challenges and Opportunities at a Global Level: A Scoping Review

BACKGROUND

Neurotrauma accounts for over 24,000 hospitalizations annually in Canada and has a significant impact in many developed countries. Among those affected, indigenous peoples are disproportionately impacted. The present scoping review explores the factors contributing to neurotrauma in indigenous populations and potential strategies to address this health care issue at a global level.

METHODS

A search was performed in Medline (1974-2021) and Embase (1946-2021) to identify studies pertaining to neurotrauma in indigenous populations of Canada. Search terms included 'Aboriginal', 'First Nation', 'Indigenous', 'traumatic brain injury', and 'traumatic spine injury'. Thematic analysis was then used to synthesize the information collected. A gray literature search was also performed.

RESULTS

The original literature search yielded 1609 articles, with 17 selected for the scoping review. Through thematic analysis, the factors contributing to neurotrauma burden in indigenous populations of Canada were summarized into 3 themes: inadequate resources available, social problems in indigenous communities, and challenges within the health care system. The potential strategies to address neurotrauma were also summarized into 3 themes: system-level changes to Canadian health care, community-based initiatives, and culturally appropriate solutions. The gray literature search revealed a lack of government reports on the topic and notable advocacy work from community organizations.

CONCLUSIONS

Systems-level interventions guided by indigenous community members will help to address the disparities that indigenous peoples face in the care and rehabilitation of neurotrauma. This study will inform further research of culturally appropriate approaches to reduce neurotrauma among indigenous peoples at a global level.

The elephant in the room: Intimate partner violence, women, and traumatic brain injury in sub-Saharan Africa

Background

Intimate partner violence (IPV) is a gendered form of violence that has been linked with traumatic brain injury (TBI). The prevalence of IPV in sub-Saharan Africa (SSA) is estimated to be one of the highest globally. Yet, little is known about the association between IPV and TBI in the SSA context. In this scoping review, we examine the intersection between IPV and TBI in SSA to identify gaps, as well as intervention opportunities.

Methods

Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses—Extension for Scoping Review (PRISMA-ScR) guidelines to guide our analyses and reporting, we searched for published articles indexed in the four largest and most comprehensive library databases: Pubmed, Embase, Web of Science and PsychInfo. Given the increasing attention that has been placed on gender disparities and health in recent years, we focused on studies published between 2010 and 2021.

Results

Our search yielded 5,947 articles and 1,258 were IPV and SSA related. Out of this, only ten examined the intersection between IPV and TBI. All focused on outcomes in female populations from South Africa (n = 5), Ghana (n = 3), Uganda (n = 1), and Cameroon (n = 1). They were a mix of qualitative studies (n = 3), neuro-imaging/biomarker studies (n = 3), case studies/reports (n = 2), quantitative surveys (n = 1) and mixed qualitative/quantitative study (n = 1). Six studies evaluated subjective reporting of IPV-induced TBI symptoms such as headaches, sleep disruptions, and ophthalmic injuries. Three examined objective assessments and included Hypothalamic-Pituitary-Adrenal (HPA) dysregulation detected by salivary cortisol levels, magnetic resonance imaging (MRI) including diffusion tensor imaging (DTI) to evaluate brain connectivity and white matter changes. One final study took a forensic anthropology lens to document an autopsy case report of IPV-induced mortality due to physical head and face trauma.

Conclusion

Our findings demonstrate that both subjective and objective assessments of IPV and TBI are possible in “resource-limited” settings. The combination of these outcomes will be critical for viewing IPV through a clinical rather than a cultural lens, and for substantiating the assertion that gender, is indeed, a social determinant of brain health.

Perceptions of Inuit Women and Non-Inuit Healthcare Providers on the Implementation of Human Papillomavirus Self-Sampling as an Alternative Cervical Cancer Screening Method in Nunavik, Northern Quebec

Human papillomavirus (HPV) self-sampling offers a cervical cancer (CC) screening alternative that can address certain barriers to the Papanicolaou test. As part of a larger community-based participatory project in Nunavik, Northern Québec, we travelled to two communities to gather perspectives from Inuit women and healthcare professionals (HCPs) on CC screening services and the possible implementation of HPV self-sampling. We held 10 group discussions with 28 Inuit women and 10 semi-structured interviews with 20 HCPs. The thematic analysis extracted themes reflecting one barrier and seven facilitators to accessing CC screening and the implementation of HPV self-sampling in Nunavik. Themes included, though not limited to, language and communication in health settings, access to culturally responsive educational resources on CC, and the noninvasive nature of HPV self-sampling. This study may serve to contribute to the co-development of a strategy for implementation that is designed according to the needs and priorities of the communities.
