Risk factors for dementia and self-harm: A linkage study.

Introduction: People living with dementia experience poor mental health and high rates of self-harm. We investigated risk factors for self-harm in people aged > 40 years living with dementia and risk factors for dementia after self-harm.

Methods: Using linked hospital data from New South Wales, Australia, we defined a dementia cohort (n = 154,811) and a self-harm cohort (n = 28,972).

Impact of post-release community mental health and disability support on reincarceration for prisoners with intellectual disability and serious mental illness in NSW, Australia.

Background: Prisoners with an intellectual disability are overrepresented in custody and more likely to reoffend and be reincarcerated compared with the general prison population. Although prisoners with intellectual disability have many of the same risk factors for recidivism as the general prison population, the high rates of mental illness experienced by this group are key drivers of recidivism.

Aims: We aimed to assess the impact of provision of post-release disability and community mental health support on rates of reincarceration in a cohort with identified intellectual disability and serious mental illness diagnosis.

Factors associated with discharge from hospital to residential aged care for younger people with neuropsychiatric disorders: an exploratory case-control study in New South Wales, Australia.

Objectives: To examine the sociodemographic and diagnostic factors associated with a discharge from hospital to residential aged care (RAC) for younger people (aged 15-64 years) with neuropsychiatric disorders.

Design: An exploratory case-control study using a historic cohort of people with neuropsychiatric disorders. Cases were people transferred to RAC on hospital discharge during the study period.

Factors associated with acute care service use after epilepsy hospitalisation in people with intellectual disability.

Background: This study aimed to identify factors associated with unplanned acute hospital readmission and emergency department (ED) presentation after hospitalisation for epilepsy in people with intellectual disability (ID).

Methods: This study is a retrospective cohort study using linked administrative datasets. We identified 3293 people with ID aged 5-64 years with a hospitalisation for epilepsy between 2005 and 2014 in New South Wales, Australia.

Mortality rate, risk factors, and causes of death in people with epilepsy and intellectual disability.

Purpose: The extent to which co-occurring intellectual disability influences mortality in people with epilepsy is largely unknown. This study compares mortality rates in people with epilepsy with and without intellectual disability and investigates causes of death and risk factors for mortality.

Method: This retrospective cohort study used linked population-based administrative datasets to derive a cohort of people with epilepsy admitted to hospital from 2005-2015 in New South Wales, Australia.

Hospital service utilisation of people previously hospitalised with different subtypes of psychotic disorder: A record linkage study.

Objective: Little research has examined the physical and mental comorbidities, and health service use patterns, of people diagnosed with psychotic disorder subtypes other than schizophrenia spectrum disorders. This study aims to examine the physical and mental comorbidities, and subsequent hospital service use patterns, of individuals previously hospitalised with various psychotic disorder subtypes using linked health service data.

Methods: We included individuals hospitalised with a psychotic disorder in New South Wales, Australia, between 1 July 2002 and 31 December 2014 (N = 63,110).

Readmission and emergency department presentation after hospitalisation for epilepsy in people with intellectual disability: A data linkage study.

Background: Despite the high prevalence of epilepsy and multiple barriers to care in people with intellectual disability, the risk of returning to hospital after an admission for epilepsy is largely unknown. In this study, we sought to quantify and compare readmission and emergency department (ED) presentations after hospitalisation for epilepsy in people with and without intellectual disability.

Methods And Findings: Using linked administrative datasets, we conducted a retrospective cohort study of people aged 5-64 years with an acute hospitalisation for epilepsy from 2005-2014 in New South Wales, Australia.

Predictors and outcomes of recognition of intellectual disability for adults during hospital admissions: A retrospective data linkage study in NSW, Australia.

Adults with intellectual disability have high health care needs. Despite frequent contact with health services, they often receive inadequate health care. One method to improve health care delivery is reasonable adjustments, that is, the adaptation of health care delivery such that barriers to participation are removed for the person with disability.

Reviewing causes of death of individuals with intellectual disability in New South Wales, Australia: a record-linkage study.

Background: People with intellectual disability (ID) have a much higher mortality rate than the general population. To reduce the rate of mortality of people with ID, it is critical that causes of death are properly understood, recorded and reported. Formal reviews of causes of death are used in some countries to ensure that causes of death are accurate.

The health service contact patterns of people with psychotic and non-psychotic forms of severe mental illness in New South Wales, Australia: A record-linkage study.

Objective: To describe and compare the health profiles and health service use of people hospitalised with severe mental illness, with and without psychotic symptoms.

Methods: We conducted a historical cohort study using linked administrative datasets, including data on public hospital admissions, emergency department presentations and ambulatory mental health service contacts in New South Wales, Australia. The study cohort comprised 169,306 individuals aged 12 years and over who were hospitalised at least once with a mental health diagnosis between 1 July 2002 and 31 December 2014.

Predictors of the Quality of Life of Informal Carers of Adults on the Autism Spectrum.

Carers of adults on the autism spectrum often experience high levels of stress, worry, and caregiver burden. There are few studies identifying the predictors of carer mental well-being and none have been conducted in Australia. Data from the Autism Cooperative Research Centre for Living with Autism's Australian Longitudinal Study of Autism in Adulthood was used to test the conceptual model by Sonido et al.

Public mental health service use by people with intellectual disability in New South Wales and its costs.

Design: Retrospective cohort data linkage analysis.

Setting, Participants: People using publicly funded in- or outpatient (admitted or non-admitted) mental health services in NSW, 2014-15.

Potentially preventable hospitalisations of people with intellectual disability in New South Wales.

Objective: To determine rates of potentially preventable hospitalisation of people with intellectual disability in New South Wales, and compare them with those for the NSW population.

Design: Retrospective cohort study.

Setting: Potentially preventable hospitalisations in NSW, as defined by the National Healthcare Agreement progress indicator 18, 1 July 2001 - 30 June 2015.

Using linked administrative data to determine the prevalence of intellectual disability in adult prison in New South Wales, Australia.

Background: Studies of the representation of people with intellectual disability (ID) in custody report widely inconsistent findings that reflect variation in how ID is defined and the methods employed for identification. Using linked administrative data may be of utility in studies of the representation of people with ID in custody. However, this approach requires an understanding of the purpose of and factors influencing identification in disparate administrative datasets.

Health Profiles, Health Services Use, and Transition to Dementia in Inpatients With Late-Life Depression and Other Mental Illnesses.

Objectives: Depression has been reported as a risk factor for dementia. We compared health and health service use profiles in older people hospitalized with late-life depression and older people hospitalized with other mental illnesses and examined the transition to dementia.

Design: A retrospective population-based study using linked administrative health data over 11 years.

Impact of disability services on mental health service utilization in adults with intellectual disability.

Background: Can disability support services (DS) facilitate access to mental health services (MHS) for people with intellectual disability? This study utilized 10 years of data from 6,260 persons in NSW who had received DS and specific MHS to quantify the relationship between DS utilization and MHS utilization in adults with intellectual disability and co-existing mental illness.

Results: Receipt of DS was associated with greater odds of accessing community mental health (CMH) services (36%, 95% CI 29%-43%) but not psychiatric admissions. Age, sex and social disadvantage did not affect the odds of psychiatric admission or CMH use.
