The Prevalence of Cognitive Impairment among People Attending a Homeless Service in Far North Queensland with a Majority Aboriginal and/or Torres Strait Islander People

Exploring and Mapping Screening Tools for Cognitive Impairment and Traumatic Brain Injury in the Homelessness Context: A Scoping Review

Cognitive impairment is common amongst people experiencing homelessness, yet cognitive screening and the collection of history of brain injury rarely features in homelessness service delivery practice. The purpose of this research was to scope and map strategies for screening for the potential presence of cognitive impairment or brain injury amongst people experiencing homelessness and identify instruments that could be administered by homelessness service staff to facilitate referral for formal diagnosis and appropriate support. A search was conducted across five databases, followed by a hand search from relevant systematic reviews. A total of 108 publications were included for analysis. Described in the literature were 151 instruments for measuring cognitive function and 8 instruments screening for history of brain injury. Tools that were described in more than two publications, screening for the potential presence of cognitive impairment or history of brain injury, were included for analysis. Of those regularly described, only three instruments measuring cognitive function and three measuring history of brain injury (all of which focused on traumatic brain injury (TBI)) may be administered by non-specialist assessors. The Trail Making Test (TMT) and the Ohio State University Traumatic Brain Injury Identification Method (OSU TBI-ID) are both potentially viable tools for supporting the identification of a likely cognitive impairment or TBI history in the homelessness service context. Further population-specific research and implementation science research is required to maximise the potential for practice application success.

Volume, scope, and consideration of ethical issues in Indigenous cognitive impairment and dementia research: A systematic scoping review of studies published between 2000-2021

INTRODUCTION

High quality research involving Indigenous people with cognitive impairment and dementia is critical for informing evidence-based policy and practice. We examined the volume, scope and ethical considerations of research related to dementia with Indigenous populations globally from January 2000-December 2021.

METHODS

Studies were included if they were published in English from 2000 to 2021 and provided original data that focused on cognitive impairment or dementia in any Indigenous population.

RESULTS

The search yielded 13,009 papers of which, 76 met inclusion criteria. The overall number of papers increased over time. Studies were mostly conducted in Australia with Aboriginal and Torres Strait Islander people (n = 30; 39%). Twenty-six papers directly involved Indigenous participants with cognitive impairment or dementia. Of these studies, ethics approval was commonly required from two or more committees (n = 23, 88.5%). Ethical and legal governance frameworks were rarely discussed.

DISCUSSION

There is a clear need for further robust studies examining cognitive impairment and dementia with Indigenous populations. Future research should consider the ethical aspects of involving Indigenous participants with cognitive impairment in research.

An integrative review of Indigenous informal caregiving in the context of dementia care

AIMS

To appraise the empirical literature on the needs of Indigenous informal caregivers caring for people living with dementia in Indigenous communities.

DESIGN

Whittemore and Knafl's updated approach to integrative reviews, PRISMA guidelines, and CASP checklists for narrative analysis were followed.

DATA SOURCES

A systematic search of published empirical literature from January 2010 to August 2020 was undertaken in six databases.

REVIEW METHODS

Fifty-one studies met the research question and the inclusion criteria.

RESULTS

Five themes describe the findings: Decolonizing Western perspectives on dementia, the centrality of cultural safety, caregivers' experiences, pre-dementia community education and family and community-centred care emerged from the thematic analysis. Most of the studies used quantitative methodologies, and few studies were conducted using community-based approaches.

CONCLUSION

This review shows that Indigenous caregiving represents an emerging field in nursing and health sciences in a context of a global crisis. Researchers need to focus on Indigenous values and voices to adapt care and support informal caregivers. Our review emphasizes that working with Indigenous communities will likely translate into new care delivery models, policies and practices to support Indigenous informal caregivers and address the specific social determinants impacting caregivers' roles and tasks.

IMPACT

This review highlights the necessity of having community and family-based discussions on enhancing the delivery of dementia care for Indigenous peoples in Canada and worldwide. Decolonizing Western perspectives of dementia translate into culturally safe approaches that aim to integrate Indigenous cultural perspectives of holism, reciprocity, wisdom, respect of older people and relationality into nursing practice. The support of Indigenous informal caregivers requires future studies to address the stigmatizing Western views of dementia.

Comparing cognitive assessment service provision between Aboriginal and Torres Strait Islanders and non-Indigenous Australians at a metropolitan health service

OBJECTIVE

Aboriginal and Torres Strait Islander populations are at a significantly higher risk of neurological and cognitive impairment from a range of aetiologies. In order to better identify and support Indigenous Australians with cognitive impairment, culturally appropriate screening, management and referral processes are critical. The primary aim of this study was to investigate the frequency of presentations and type of cognitive screening conducted with Indigenous Australians presenting to health services.

METHODS

Hospital data for 30 Indigenous Australians presenting with neurological symptoms to Emergency Departments within a large metropolitan health service were compared with a group of 30 non-Indigenous, Australian-born, English-speaking, age-, gender- and diagnosis-matched individuals.

RESULTS

Only two individuals, one from each group, received cognitive screening. This was likely related to a surprisingly large proportion of Indigenous Australians presenting to hospital with headache and migraine. Significantly more Indigenous Australians (36.7%) were consulted by a member of the multidisciplinary team compared to 10% of the non-Indigenous group. No differences in follow-up referrals were observed.

CONCLUSIONS

Results indicated a lack of cognitive screening practices being undertaken in both groups. It was encouraging to see Indigenous Australians receiving consultations from multidisciplinary team members at a higher rate, with a similar follow-up pathway being observed. This study further highlights the need for adoption of screening practices in primary health care settings and the development and use of culturally appropriate cognitive screening measures. SO WHAT?: This study investigates the cognitive screening practices of a metropolitan health service and highlights the need for culturally appropriate cognitive screening methods to be developed and implemented to facilitate the identification of cognitive impairment in Indigenous Australians presenting for treatment.

Exploring the experiences and needs of homeless aboriginal and torres strait islander peoples with neurocognitive disability

Objective:

The current study explored the experiences and aspirations of a cohort of Aboriginal and Torres Strait Islander adults with neurocognitive disability residing in a homeless shelter in regional Queensland, Australia. Neurocognitive disability (NCD) refers to any acquired disorder or injury to the brain where the primary clinical deficit is in cognitive function.

Method:

The data reported on in this paper emerged from a broader study that aimed to understand the extent and nature of neurocognitive disability amongst homeless Aboriginal and Torres Strait Islander people. The broader study found high levels of NCD which impacted on people’s ability to participate in society. As part of the study, qualitative information was sought regarding participant life experiences. A culturally safe and acceptable structure of “past, present and future” was applied to open-ended questions.

Results:

Thematic analysis of the data identified four broad themes of i) normalisation of illness and disability; ii) trauma and loss; iii) socioeconomic disadvantage; and iv) hope and disempowerment. This paper reports on these themes and experiences, which occurred across the life span, intersected with NCD, and contributed to what we have termed ‘complex disablement’ amongst this cohort.

Conclusions:

While causal links between life experience, disability and disablement are not always clear, our findings suggest that attempts to address homelessness must engage with this complexity. The application of holistic, intersectoral supports, which encompass culturally informed, community driven approaches are needed. Understanding the impacts of individual and intergenerational trauma is crucial to safe and effective service provision for this cohort.
