An assessment of intellectual disability among Aboriginal Australians

Colonial drivers and cultural protectors of brain health among Indigenous peoples internationally

Despite relatively higher rates of dementia among Indigenous populations internationally, research into drivers of disparities in brain health and cognitive function has tended to focus on modifiable risk factors over cultural understandings and contextual determinants. By seeking to characterize social and cultural factors that shape brain health and cognition in Indigenous populations, this mini scoping review expands prevailing schools of thought to include Indigenous knowledge systems. This reveals important gaps in culturally aligned care. It also reclaims horizons for research important to Indigenous Peoples that have garnered diminished attention in biomedical approaches. Twenty-three sources were included for data extraction. This synthesis of 23 sources includes health communication about dementia, health provider knowledge about Indigenous health, culturally relevant screening and assessment tools, and culturally grounded care models. Much of the focus is currently still on modifiable risk factors that reside at individual factors, whereas attention to wider social factors that impact populations is needed, as stressors through isolation, discrimination, and unequal care are widely reported. Going forward, identifying structural barriers to living well and recognizing the importance of connection to culture will benefit both Indigenous and non-Indigenous understandings of brain health.

Effect of an ageing population on services for the elderly in the Northern Territory

Objective The aim of the present study was to describe the elderly population of the Northern Territory (NT), explore the challenges of delivering aged care services to this population and implications for the acute care sector. Methods Data gathered from a variety of sources were used to describe the demographic and health profile of elderly Territorians, the aged care structure and services in the NT, and admission trends of elderly patients in NT hospitals. Information regarding NT community and residential aged care services was sourced from government reports. NT public hospital admissions from 2001 to 2015 were adjusted by the estimated Aboriginal and non-Aboriginal populations. Results In 2015, elderly people constituted 9.2% of the NT population and this number is predicted to increase. Between 2001 and 2015, the number and rate of elderly admissions to NT public hospitals increased significantly. Compared with other jurisdictions, aged care in the NT is dominated by community services, which are of limited scope. Important geographical and economic factors affect the availability of residential aged care beds. This, in turn, affects the ability of elderly people to transition from hospital settings. Conclusions The NT has a relatively small but growing elderly population with increasing needs. This population is markedly different compared with its counterparts in other Australian states and territories, but receives aged care services based on national policies. Recent changes to community-based services and increases in residential beds should improve services and care, although remaining challenges and gaps need to be addressed. What is known about the topic? Increasing health and care needs of elderly people will place significant stress across the health and aged care system. In Australia, most aged care services are apportioned and funded under a national system. The NT has a markedly different population profile compared with the rest of Australia, which gives rise to unique considerations, but its aged care structure is based on nationally developed policies. What does this paper add? Elderly people in the NT are increasingly using acute care services. Aged care services in the NT have higher ratios of community-based services to residential aged care facilities (RACF) as a consequence of a 'younger' cohort of Aboriginal elderly people who live remotely. In addition, economic factors affect the low number of RACF places. As evidenced in past years, a small pool of beds can adversely affect the numbers and length of stay of elderly people waiting in hospitals. What are the implications for practitioners? The NT has a small but growing population of elderly people, which will place an increasing burden on acute care services that are ill equipped to manage their specific needs. Recent RACF and flexible care bed approvals may alleviate past difficulties to transition hospital patients awaiting RACF placement. Significant changes at the national level to community-based care services that increase flexibility for providers may bring about better outcomes for remote elderly recipients. However, high costs and issues with remote servicing will remain. Psychogeriatrics remains a major underserviced area in the NT with no prospective solution.

Building workforce capacity in Australia and New Zealand: a profile of psychiatrists with an interest in intellectual and developmental disability mental health

OBJECTIVE:

To describe the characteristics of psychiatrists working in the area of intellectual and developmental disability mental health (IDDMH) across Australia and New Zealand.

METHODS:

A secondary analysis of data collected by the Royal Australian and New Zealand College of Psychiatrists 2014 workforce survey. Characteristics of the IDDMH workforce ( n=146 psychiatrists) were compared with those of the broader psychiatry workforce ( n=1050 psychiatrists).

RESULTS:

The IDDMH workforce were more likely than the broader psychiatry workforce to be working across both the public and private health sectors, be engaged in outreach work, endorse specialty practice areas pertinent to IDDMH, treat younger patients and work more clinical hours per week. Part-time status and retirement plans of the IDDMH workforce matched those of the broader psychiatry workforce.

CONCLUSIONS:

While some elements of the IDDMH workforce profile suggest this workforce is tailored to the needs of the population, the potential shortage of IDDMH psychiatrists highlights the need for the development of a specific training programme and pathway in this area.

Intellectual disability and Aboriginal Australians – training needs for psychiatrists

Aboriginal Australians have relatively high rates of intellectual disability, a situation that is probably due mainly to poor health and social disadvantage. Populations with high rates of intellectual disability are more at risk of developmental disorders and mental ill health. We explore the training needs for psychiatrists working with indigenous people and how they can be met.

Making every Australian count: challenges for the National Disability Insurance Scheme (NDIS) and the equal inclusion of homeless Aboriginal and Torres Strait Islander Peoples with neurocognitive disability

This article highlights the dearth of accurate evidence available to inform the National Disability Insurance Scheme (NDIS) regarding the extent and nature of neurocognitive disability amongst homeless Aboriginal and Torres Strait Islander people. Without accurate prevalence rates of neurocognitive disability, homeless Aboriginal and Torres Strait Islander people are in danger of not being counted by the NDIS and not receiving supports to which they are entitled. Addressing this knowledge gap is challenged by a range of factors, including: (1) the long-term effect of profound intergenerational disenfranchisement of Aboriginal and Torres Strait Islander people; (2) Aboriginal and Torres Strait Islander cultural perspectives around disability; (3) the generally unrecognised and poorly understood nature of neurocognitive disability; (4) the use of research methods that are not culturally safe; (5) research logistics; and (6) the absence of culturally appropriate assessment tools to identify prevalence. It is argued that an accurate evidence base that is informed by culturally safe research methods and assessment tools is needed to accurately guide the Commonwealth government and the National Disability Insurance Agency about the expected level of need for the NDIS. Research within this framework will contribute to the realisation of a truly inclusive NDIS.

Chronic Respiratory Disorders and Their Treatment among Older People with Intellectual Disability and/or Autism Spectrum Disorder in Comparison with the General Population

Respiratory disorders are common among people with intellectual disabilities (ID). However, few studies have investigated these disorders among older people with ID. We identified 7936 people, aged 55+ years, with ID and a reference cohort from the general population. Data on diagnoses of chronic respiratory disorders, with a focus on asthma and chronic obstructive pulmonary disease (COPD), were collected, as was information on health care visits due to such disorders. We also added data on the prescription of drugs for obstructive airway diseases. Whereas the risk of having at least one diagnosis of asthma during the study period was similar in the two cohorts, people with ID were less likely than the general population to have been diagnosed with COPD. The same was found for health care visits due to asthma and COPD, respectively. The patterns of drug prescription were similar among people with ID and the general population, with the exception of adrenergics for systemic use, which were more commonly prescribed to people with ID. Thus, older people with ID do not seem to have an increased risk of asthma or COPD. Moreover, the indications are that when diagnosed with any of these disorders, they receive treatment adapted to their particular needs.

Aboriginal prisoners and cognitive impairment: the impact of dual disadvantage on Social and Emotional Wellbeing

BACKGROUND

Negligible information is available regarding the Social and Emotional Wellbeing (SEWB) needs of Aboriginal Australian individuals in custody with cognitive impairment. This is problematic given that Aboriginal people with cognitive impairment often experience dual disadvantage in the context of the justice system. This study sought to ascertain the relationship between cognitive impairment and mental health/cultural needs (SEWB) Aboriginal and Torres Strait Islander people in custody.

METHOD

A sample of 122 Aboriginal and Torres Strait Islander people were administered a culturally themed semi-structured questionnaire in custodial settings in Victoria, Australia. The questionnaire included measures of cognitive impairment, SEWB and forensic needs. Analyses were performed to determine differences in the presence of SEWB and unmet custodial needs by level of cognitive impairment.

RESULTS

Findings revealed a diminished level of wellbeing for cognitively impaired participants across several factors. Cognitive impairment was associated with poorer coping mechanisms, additional experiences of racism, difficulties handling emotions, discomfort around non-Aboriginal people and reduced access to meaningful activities in custody. All participants regardless of their level of impairment recognised the importance of cultural engagement; however, cognitively impaired participants had greater difficulty accessing/practicing cultural activities.

CONCLUSIONS

Culturally responsive disability assistance should be available at all phases of the justice system for Indigenous people with cognitive impairment to ensure that equitable care is accessible and needs are addressed.

Intellectual disability in Indigenous Australians: issues and challenges

OBJECTIVES

Literature on Indigenous Australians (Aboriginal and Torres Strait Islander people) and intellectual disability (ID) is summarized in order to identify current state of knowledge, gaps, and areas for further research.

METHODS

A selective review of psychiatric literature using relevant medical databases was undertaken. Key articles were identified and their findings described.

RESULTS

ID is reported to be more prevalent in Indigenous Australians. Sociocultural constructs and a lack of validated psychometric measures affect what is considered to be ID in Indigenous communities. Prenatal, perinatal, and postnatal factors impair brain development and contribute to ID in Indigenous communities. Comorbid physical and psychiatric disorders need to be assessed and managed.

CONCLUSIONS

ID is an emerging area of health concern for general and mental health professionals working with Indigenous Australians. This important area requires further research, appropriate training, and resourcing.

Intellectual disability and indigenous Australians: an overview

The review summarizes important literature in the emerging field of intellectual disability (ID) in indigenous Australians. Search of various electronic databases revealed 19 papers that provide information regarding prevalence, sociodemographic factors, and issues in assessment and management. Overall, there is limited information regarding ID in indigenous Australians, which is reported to be more prevalent compared with nonindigenous Australians. Sociocultural constructs affect what is considered to be ID in indigenous communities and this may be at odds with western notions. Other difficulties include lack of validated psychometric instruments to effectively measure cognitive functioning in indigenous Australians. Prenatal, perinatal, and postnatal factors are significant factors that impair brain development and contribute to ID in indigenous communities. Comorbid physical and psychiatric disorders need to be assessed and managed. This paper provides an overview of current knowledge regarding this important area that requires further research, appropriate training, and resourcing.

Mental health at the intersections: the impact of complex needs on police contact and custody for Indigenous Australian men

Indigenous Australians experience significant social risk, vulnerability and disadvantage. Nowhere is this more starkly demonstrated than in the levels of contact that Indigenous Australians have with the criminal justice system, particularly the police. Utilizing a linked dataset of extant criminal justice, human and health service administrative data in New South Wales (NSW) Australia, this paper explores patterns of police contact and custody for a cohort of Indigenous males with complex needs. Four significant factors are identified that alone or in combination appear to impact on the frequency with which these men experience police contact and custody, including young age at first police contact, experiencing out of home care as a child, alcohol misuse, and limited locational mobility. Whilst it might be expected that the presence of mental ill-health and/or cognitive disability would be a key predictor of the frequency and intensity of police contact and custody, the findings suggest rather that the presence of multiple disadvantages beginning in the early years and compounding throughout individuals' lives, in which mental illness may or may not be a factor, is more significant than the presence of any one diagnosis in precipitating police contact and custody for this group.

Psychosis and its correlates in a remote indigenous population

OBJECTIVES

The aim of this study was to describe prevalence and characteristics of psychotic disorders in a remote Indigenous population.

METHOD

Clinical review of all patients with an active diagnosis of a psychotic disorder in remote communities of Cape York and the Torres Strait.

RESULTS

170 patients were identified and demographic, social and treatment variables described.

CONCLUSIONS

Psychotic disorders are common and more so among young adult Aboriginal men, with high rates of comorbid conditions including substance use, intellectual impairment and diabetes. In parallel to this case complexity, there are high rates of coercive treatments. Certain differences by ethnicity and location are described and possible explanations proposed.

'Radical hope' and rain: climate change and the mental health of Indigenous residents of northern Australia

Objective: This paper considers the short, intermediate and longer term effects of climate change in relation to the mental health of Indigenous residents of northern Australia, and what these effects mean in terms of supporting adaptation and resilience. Conclusions: Indigenous Australians have contended with change for millennia, with the drivers shifting from ecological to social pressures since European colonization. Climate change resulting from human activities introduces a new set of change forces which will in the short term be mediated by economic and social effects internationally.

Linked data: opportunities and challenges in disability research

BACKGROUND

Disability research data often exist in the form of individual records located within discrete registers that may extend across sensitive political boundaries.

METHOD

This paper discusses the opportunities and challenges associated with using linked health and administrative data for disability research, with examples from research projects conducted both in Australia and overseas.

RESULTS

Linked data offer distinct value in providing a comprehensive profile for a range of health issues, such as morbidity, mortality, assessing health care costs and/or quality of service provision.

CONCLUSIONS

While the use of record linkage in health research is not a novel concept, recent advances in technology and electronic data management plus improved data linkage protocols have markedly increased the feasibility and opportunity for successfully utilising data linkage for the purposes of research, while at the same time protecting the privacy of the individual. An awareness and appropriate management of the associated challenges is required to maximise the outcomes of disability research using linked data.

The relationship between intellectual disability, Indigenous status and risk of reoffending in juvenile offenders on community orders

BACKGROUND

Intellectual disability (ID), age and aboriginal status have been independently implicated as risk factors for offending to varying degrees. This study examined the relationship between age, ID and the Indigenous status of juvenile offenders. It also examined the outcomes of the sample's offending in terms of court appearances and sentencing, criminogenic needs and risk of reoffending.

METHOD

The sample comprised 800 juvenile offenders on community orders of whom 19% were Indigenous, who completed the New South Wales Young People on Community Order Health Survey between 2003 and 2005. Risk and criminogenic needs were evaluated using the Youth Level of Service/Case Management Inventory (Australian Adaptation) (YLS/CMI: AA).

RESULTS

Those with an ID were found to have a higher risk of reoffending than those without an ID. Those with an ID were also more likely to be younger and Indigenous. For Indigenous young offenders, there was no difference between those with and without an ID in risk category allocation or number of court dates. For non-Indigenous young offender, those with an ID had higher risk scores and more court dates.

CONCLUSIONS

This study provided evidence that Indigenous status may play a significant role in the relationship between ID and offending in juvenile offenders on community orders. These findings have clear implications for the 'risk', 'needs' and 'responsivity' principles of offender classification for treatment. Emphasis is placed on the requirement for addressing the needs of Indigenous juvenile offenders with an ID.
