Genetic and environmental influences on fruit and vegetable consumption and depression in older adults.

BACKGROUND: Prior work suggests that higher fruit and vegetable consumption may protect against depression in older adults. Better understanding of the influence of genetic and environmental factors on fruit and vegetable intakes may lead to the design of more effective dietary strategies to increase intakes. In turn this may reduce the occurrence of depression in older adults. OBJECTIVES: The primary aim of this study is to estimate the genetic and environmental influences on the consumption of fruit and vegetables in older adults. The secondary aim is an exploratory analysis into possible shared genetic influences on fruit and vegetable intakes and depression. METHODS: Analysis of observational data from 374 twins (67.1% female; 208 monozygotic (MZ); 166 dizygotic (DZ)) aged ≥ 65 years drawn from the Older Australian Twins Study. Dietary data were obtained using a validated food frequency questionnaire and depressive symptoms were measured using the 15-item short form Geriatric Depression Scale. The contribution of genetic and environmental influences on fruit and vegetable intake were estimated by comparing MZ and DZ twin intakes using structural equation modelling. A tri-variate twin model was used to estimate the genetic and environmental correlation between total fruit and vegetable intakes and depression. RESULTS: In this study, vegetable intake was moderately influenced by genetics (0.39 95%CI 0.22, 0.54). Heritability was highest for brassica vegetables (0.40 95%CI 0.24, 0.54). Overall fruit intake was not significantly heritable. No significant genetic correlations were detected between fruit and vegetable intake and depressive symptoms. CONCLUSIONS: Vegetable consumption, particularly bitter tasting brassica vegetables, was significantly influenced by genetics, although environmental influences were also apparent. Consumption of fruit was only influenced by the environment, with no genetic influence detected, suggesting strategies targeting the food environment may be particularly effective for encouraging fruit consumption.

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). We examined the demographic profile of the cohort and rates of subsequent acute hospital care and ambulatory mental health service use. We compared the rates of subsequent hospital admissions, emergency department presentations and ambulatory mental health treatment days of people hospitalised with different psychotic disorder subtypes to people hospitalised with schizophrenia spectrum disorders using Poisson regression. RESULTS: People most recently hospitalised with mood/affective disorders and psychotic symptoms had a higher rate of subsequent hospital admissions than those most recently hospitalised with schizophrenia spectrum and delusional disorders (adjusted incident rate ratio = 1.06; 95% confidence interval = [1.02, 1.10]), while people most recently hospitalised with drug-induced and other organic (adjusted incident rate ratio = 1.19; 95% confidence interval = [1.12, 1.27]) and acute psychotic disorders (adjusted incident rate ratio = 1.10; 95% confidence interval = [1.03, 1.18]) had more subsequent emergency department presentations than those most recently hospitalised with schizophrenia spectrum and delusional disorders. All three groups had fewer subsequent mental health ambulatory days than those most recently hospitalised with schizophrenia spectrum and delusional disorders (adjusted incident rate ratios = 0.85-0.91). CONCLUSION: The health profiles and subsequent hospital service use patterns of people previously hospitalised with different psychotic disorder subtypes are heterogeneous, and research is needed to develop targeted health policies to meet their specific health needs.

A scoping review of registered nurses' delegating care and support to unlicenced care and support workers.

AIM: To scope the international literature about registered nurses delegated models of care to unlicenced workers, identify gaps and reflect upon how the evidence relates to nursing in multiple contexts. DESIGN: Scoping review of the peer reviewed literature from the year 2000 onwards, using the PRISMA-ScR checklist. METHODS: The study searched the following databases in February 2022: CINAHL, Medline, ProQuest, and SCOPUS, and included keywords, Boolean operators and subject headings relevant to registered nurses delegating the provision of care to unlicenced workers. RESULTS: A total of 49 articles met the eligibility criteria for this study, and relevant data were extractedThree models of delegation were highlighted within the literature: direct, indirect and a mixture of both. The data highlighted that direct delegation mainly occurred in acute contexts, with delegation decreasing with increasing patient acuity and/or complexity but the threshold of when this would occur was not clear. There was one intervention study that measured patient outcomes which could aid in the determination of what is effective delegation. For studies that did report on it (n = 6), there were few examples of better patient outcomes in cases where care was delegated from registered nurses to unlicenced workers. CONCLUSIONS: The scoping review highlighted heterogeneity in practice areas and methods of delegation practice. A key gap in literature is the absence of studies focusing on patient outcomes, with a clear baseline to measure and identify effective delegation practices. Additionally, the legal and logistical implications presented in both direct and indirect delegation practices is not evident in the literature. IMPLICATIONS FOR THE PROFESSION: Decisions related to delegation are often made at the service level and prescribed to those who work within the service, suggesting that models of indirect delegation are in fact not delegation at all, rather a re-distribution of nurses' work. RELEVANCE TO CLINICAL PRACTICE: Delegation is a vital component of the scope of practice of registered nurses. This review has highlighted unique differences in delegation by practice context, where the proliferation of unlicensed workers in certain contexts places a vastly different professional and legal burden on the registered nurse.

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). Using survival analyses, we investigated predictors of self-harm for the dementia cohort, and predictors of dementia for the self-harm cohort. RESULTS: We found self-harm or dementia diagnoses occurred most often within 24 months of a dementia diagnosis or initial self-harm presentation, respectively. Men living with dementia, and people with complex psychiatric profiles, had the greatest risk of self-harm. Men who had self-harmed had the greatest risk of dementia diagnoses. DISCUSSION: Men and people with complex psychiatric profiles and dementia may particularly benefit from post-diagnosis mental and behavioral support to reduce risk of self-harm.

The heritability of amyloid burden in older adults: the Older Australian Twins Study.

OBJECTIVE: To determine the proportional genetic contribution to the variability of cerebral ß-amyloid load in older adults using the classic twin design. METHODS: Participants (n=206) comprising 61 monozygotic (MZ) twin pairs (68 (55.74%) females; mean age (SD): 71.98 (6.43) years), and 42 dizygotic (DZ) twin pairs (56 (66.67%) females; mean age: 71.14 (5.15) years) were drawn from the Older Australian Twins Study. Participants underwent detailed clinical and neuropsychological evaluations, as well as MRI, diffusion tensor imaging (DTI) and amyloid PET scans. Fifty-eight participants (17 MZ pairs, 12 DZ pairs) had PET scans with 11Carbon-Pittsburgh Compound B, and 148 participants (44 MZ pairs, 30 DZ pairs) with 18Fluorine-NAV4694. Cortical amyloid burden was quantified using the centiloid scale globally, as well as the standardised uptake value ratio (SUVR) globally and in specific brain regions. Small vessel disease (SVD) was quantified using total white matter hyperintensity volume on MRI, and peak width of skeletonised mean diffusivity on DTI. Heritability (h2) and genetic correlations were measured with structural equation modelling under the best fit model, controlling for age, sex, tracer and scanner. RESULTS: The heritability of global amyloid burden was moderate (0.41 using SUVR; 0.52 using the centiloid scale) and ranged from 0.20 to 0.54 across different brain regions. There were no significant genetic or environmental correlations between global amyloid burden and markers of SVD. CONCLUSION: Amyloid deposition, the hallmark early feature of Alzheimer's disease, is under moderate genetic influence, suggesting a major environmental contribution that may be amenable to intervention.

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. Of these, 63,110 had a recorded psychotic illness and 106,196 did not. Outcome measures were rates of hospital, emergency department and mental health ambulatory service utilisation, analysed using Poisson regression. RESULTS: People with psychotic illnesses had higher rates of hospital admission (adjusted incidence rate ratio (IRR) 1.26; 95% confidence interval [1.23, 1.30]), emergency department presentation (adjusted IRR 1.17; 95% confidence interval [1.13, 1.20]) and ambulatory mental health treatment days (adjusted IRR 2.90; 95% confidence interval [2.82, 2.98]) than people without psychotic illnesses. The higher rate of hospitalisation among people with psychotic illnesses was driven by mental health admissions; while people with psychosis had over twice the rate of mental health admissions, people with other severe mental illnesses without psychosis (e.g. mood/affective, anxiety and personality disorders) had higher rates of physical health admissions, including for circulatory, musculoskeletal, genitourinary and respiratory disorders. Factors that predicted greater health service utilisation included psychosis, intellectual disability, greater medical comorbidity and previous hospitalisation. CONCLUSION: Findings from this study support the need for (a) the development of processes to support the physical health of people with severe mental illness, including those without psychosis; (b) a focus in mental health policy and service provision on people with complex support needs, and (c) improved implementation and testing of integrated models of care to improve health outcomes for all people experiencing severe mental illness.

Networks of inflammation, depression, and cognition in aging males and females.

BACKGROUND: Prioritizing the maintenance of healthy cognitive aging and personalizing preventive interventions to enhance their effectiveness is crucial as the global population ages. Systemic inflammation and depression in older people have been associated with decreased levels of cognition but results have been inconsistent. AIMS: To explore the interactive network of inflammation, depression and cognition by sex in older people. METHODS: We used novel network analysis to explore the unique associations between inflammatory biomarkers, depression, cognition, and somatic, genetic, and lifestyle risk factors in an older (aged 70-90 years), non-demented, community-dwelling sample from the longitudinal Sydney Memory and Aging Study (N = 916) at baseline and at a two-year follow-up. RESULTS: The networks of biomarkers, depression, cognition, and relevant covariates were significantly different between males and females. A stable negative link between depression and cognition was found in females only; a stable positive association between biomarker interleukin-6 and depression was found in females only; and a stable positive association between biomarker interleukin-8 and alcohol was found in females only. For both males and females, a stable, positive relationship was found between the presence of APOE-ε4 gene and biomarker C-reactive protein; between education and cognition; and between biomarker interleukin-6 and all other biomarkers. CONCLUSIONS: These findings suggest different psychophysiological mechanisms underlie the interactive network of biomarkers, depression and cognition in males and females that should be considered when designing personalized preventive interventions to maintain cognitively healthy aging.

Registered nurses' awareness and implementation of reasonable adjustments for people with intellectual disability and/or autism.

AIM: To describe Australian registered nurses' awareness, and implementation of reasonable adjustments within their practice when caring for people with intellectual disability and/or autism. Additionally, the association between key demographic, workforce, and respondent variables and familiarity of the term and regularity of use was explored. DESIGN: Cross-sectional survey. METHODS: Survey data were collected between August and October 2020 using an online survey tool. Data were analysed using descriptive and inferential statistics. RESULTS: Familiarity of the concept of reasonable adjustments was relatively low, compared to respondents who report applying adjustments when caring for people with intellectual disability and/or autism. Higher levels of confidence, comfort, and knowledge when caring for this cohort were associated with greater awareness and application of reasonable adjustments. CONCLUSION: A higher volume, and diversity in type of, nursing education related to care for people with intellectual disability and/or autism is indicated.

A cross-practice context exploration of nursing preparedness and comfort to care for people with intellectual disability and autism.

AIMS AND OBJECTIVES: To compare the self-perceived preparedness, knowledge, comfort and confidence of Australian Registered Nurses when caring for people with ID and/or ASD across contexts of practice: primary care and community, intensive care, acute hospital, emergency department, paediatrics and ID/ASD. BACKGROUND: There is limited research comparing nursing preparedness and competency when caring for people with intellectual disability (ID) and/or autism (ASD) across nursing contexts of practice. A greater understanding of the differed educational preparedness, confidence and comfort across contexts of practice can aid the development of tailored educational programmes to improve nursing capacity to care for this cohort. DESIGN: Cross-sectional descriptive study. METHODS: A descriptive survey tool of registered nurses (n = 69.3). Comparative inferential analysis was undertaken between the independent categorical variable of six nursing contexts of practice across several dependent variables including age, years since registration, educational content and exposure, knowledge, comfort and confidence. This cross-sectional study was undertaken according to the STROBE Statement checklist of items. RESULTS: Occupying an ID/ASD nursing role was significantly associated with higher reported levels of educational preparedness, professional development and postgraduate education relevant to caring for people with ID and/or ASD. Levels of self-reported knowledge of care issues, confidence and comfort when undertaking healthcare tasks was significantly associated with the context of practice, with nurses working in ID/ASD settings reporting the highest levels across all variables. CONCLUSION: The findings of the study highlight an association between greater educational exposure to content relevant to working with people with ID/ASD and subsequently working in that field. RELEVANCE TO CLINICAL PRACTICE: This study has highlighted that professional development programmes aiming to improve nursing capacity to care for people with ID and/or ASD, should be informed by and address differing gaps in confidence, comfort and educational preparedness across nursing contexts of practice.

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. PARTICIPANTS: Data collected in a retrospective data linkage study of 92 542 people with intellectual disability in NSW; potentially preventable hospitalisations data for NSW published by HealthStats NSW. MAIN OUTCOME MEASURES: Age-adjusted rates of potentially preventable hospitalisation by group (people with intellectual disability, NSW population), medical condition type (acute, chronic, vaccine-preventable), and medical condition. RESULTS: The annual age-standardised rate for people with intellectual disability ranged between 5286 and 6301 per 100 000 persons, and for the NSW population between 1278 and 1511 per 100 000 persons; the rate ratio (RR) ranged between 3.5 (95% CI, 3.3-3.7) in 2014-15 and 4.5 (95% CI, 4.2-4.9) in 2002-03. The difference was greatest for admissions with acute (RR range: 5.3 [95% CI, 4.9-5.7] in 2014-15 to 8.1 [95% CI, 7.4-8.8] in 2002-03) and vaccine-preventable conditions (RR range: 2.1 [95% CI, 1.6-3.0] in 2007-08 to 3.4 [95% CI, 2.2-5.2] in 2004-05). By specific condition, the highest age-standardised rate was for admissions with convulsions and epilepsy (all years, 2567 per 100 000 population; v NSW population: RR, 22.2; 95% CI, 21.3-23.1). CONCLUSION: Age-standardised rates of potentially preventable hospitalisation are higher for people with intellectual disability than for the general population. The reasons for these differences should be investigated, and strategies for averting potentially preventable hospitalisation developed.

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

OBJECTIVES: To describe the population characteristics of people with intellectual disability in New South Wales; to quantify and compare public mental health service use and costs for people with and without intellectual disability in NSW during 2014-15. 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. MAIN OUTCOME MEASURES: Numbers of bed days (inpatient mental health services), and treatment days (ambulatory mental health); costs of publicly funded mental health services. RESULTS: People with intellectual disability comprised 1.1% of the NSW population, but 6.3% of people who used public mental health services; 12% of public mental health costs during 2014-15 were for people with intellectual disability. Compared with metropolitan local health districts (LHDs), overall public mental health service costs were lower for rural and regional LHDs (adjusted incidence rate ratio [aIRR], 0.8; 95% CI, 0.8-0.9) and higher for specialty networks (aIRR, 1.2; 95% CI, 1.1-1.3). Per person costs for people with intellectual disability were higher than for those without intellectual disability (aIRR, 2.6; 95% CI, 2.2-3.0). CONCLUSION: People with intellectual disability use public mental health services to a greater degree than other people. They should be explicitly considered by all tiers of mental health policy and service planning in Australia. Population health planning for the needs of people with disabilities would be assisted by including disability identifiers in all health administrative data sets.

Global and Regional Development of the Human Cerebral Cortex: Molecular Architecture and Occupational Aptitudes.

We have carried out meta-analyses of genome-wide association studies (GWAS) (n = 23 784) of the first two principal components (PCs) that group together cortical regions with shared variance in their surface area. PC1 (global) captured variations of most regions, whereas PC2 (visual) was specific to the primary and secondary visual cortices. We identified a total of 18 (PC1) and 17 (PC2) independent loci, which were replicated in another 25 746 individuals. The loci of the global PC1 included those associated previously with intracranial volume and/or general cognitive function, such as MAPT and IGF2BP1. The loci of the visual PC2 included DAAM1, a key player in the planar-cell-polarity pathway. We then tested associations with occupational aptitudes and, as predicted, found that the global PC1 was associated with General Learning Ability, and the visual PC2 was associated with the Form Perception aptitude. These results suggest that interindividual variations in global and regional development of the human cerebral cortex (and its molecular architecture) cascade-albeit in a very limited manner-to behaviors as complex as the choice of one's occupation.

Expert consensus on the operation of an adult tertiary intellectual disability mental health service in New South Wales, Australia.

OBJECTIVE: To identify and reach consensus on the priorities and operation of an adult tertiary intellectual disability mental health service in New South Wales, Australia. METHOD: An online Delphi consultation was conducted with 25 intellectual disability mental health experts. RESULTS: Participants agreed that the service should involve a multidisciplinary team and accept people with an intellectual disability aged over 15 years with complex needs and/or atypical presentations. Agreed service roles included short-term assessment, diagnosis and treatment, providing high-level clinical advice, and capacity building. Endorsed principles and practical ways of working align with existing guidelines. CONCLUSIONS: This study describes experts' views on how an adult tertiary intellectual disability mental health service should operate in New South Wales. Further consultation is needed to determine the views of people with an intellectual disability and mental health staff.

Has teaching about intellectual disability healthcare in Australian medical schools improved? A 20-year comparison of curricula audits.

BACKGROUND: People with intellectual disability (ID) have multiple and complex health needs, more frequent healthcare episodes, and experience poorer health outcomes. Research conducted two decades ago showed that medical professionals were lacking in the knowledge and skills required to address the complex needs of this patient group. The aim of the current study was to determine whether Australian undergraduate medical schools that offer ID health education content had changed the amount and nature of such teaching over this period. METHODS: Identical or equivalent questionnaire items were compared across eight Australian medical schools that participated in curricula audits conducted in 1995 (referred to as T1) and 2013/14 (T2). The audits were of the nature of the ID content, methods used to teach it, and who taught it. RESULTS: There was no significant difference in the number of hours of compulsory ID content offered to medical students at T2 (total = 158.3 h; median = 2.8 h per ID unit) compared with T1 (total = 171 h; median = 2.5 h). At T2 compared with T1, units with ID content taught in the area of general practice had increased (2 units; 3.6% to 7 units; 16.3%), while decreases were seen in paediatrics (22 units; 40.0% to 10 units; 23.3%) and psychiatry (10 units; 18.2% to 4 units; 9.3%). The number of schools using problem- and/or enquiry-based learning rose to six at T2 from one at T1. Inclusive teaching practices (people with ID develop or deliver content) in compulsory/elective units had increased at T2 (10 units; 23.3%) compared with T1 (6 units; 10.9%), but direct clinical contact with people with ID had decreased (29 units; 52.7% to 11 units; 25.6%). CONCLUSIONS: Overall, little progress has been made to address the gaps in ID education for medical students identified from an audit conducted in 1995. Renewal of ID content in medical curricula is indicated as a key element in efforts to improve workforce capacity in this area and reduce barriers to care, with the aim of reversing the poor health outcomes currently seen for this group.

A cross-national study of depression in preclinical dementia: A COSMIC collaboration study.

INTRODUCTION: Depression commonly accompanies Alzheimer's disease, but the nature of this association remains uncertain. METHODS: Longitudinal data from the COSMIC consortium were harmonized for eight population-based cohorts from four continents. Incident dementia was diagnosed in 646 participants, with a median follow-up time of 5.6 years to diagnosis. The association between years to dementia diagnosis and successive depressive states was assessed using a mixed effect logistic regression model. A generic inverse variance method was used to group study results, construct forest plots, and generate heterogeneity statistics. RESULTS: A common trajectory was observed showing an increase in the incidence of depression as the time to dementia diagnosis decreased despite cross-national variability in depression rates. DISCUSSION: The results support the hypothesis that depression occurring in the preclinical phases of dementia is more likely to be attributable to dementia-related brain changes than environment or reverse causality.

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. Individuals living in a remote area had greater odds of CMH use and lesser odds of psychiatric admission. CONCLUSIONS: Receipt of DS was associated with greater CMH but not psychiatric hospital utilization in people with intellectual disability and co-existing mental illness.

Factors associated with death in people with intellectual disability.

BACKGROUND: People with intellectual disability (ID) experience higher mortality than the general population. This study examines factors contributing to deaths in people with intellectual disability. METHOD: Linked administrative data spanning ten years for 49,947 people with intellectual disability receiving disability services were analysed to assess the impact of demographic variables, comorbidities and health service utilization on the risk of death using Cox proportional hazard models. RESULTS: People admitted for cancer were 8 times more likely to die within the study period compared to people not admitted for cancer. Down syndrome, cerebral palsy and heart disease also increased the risk of death. Emergency department presentations and/or mental health admissions increased the risk of death 4 times. CONCLUSIONS: Our findings provide a basis for policy changes and public health interventions. Cancer screening, mental health interventions, inclusion of people with intellectual disability in health policy and improved health care are needed to meet the needs of this population.

Subspecialty training pathways in intellectual and developmental disability psychiatry in Australia and New Zealand: current status and future opportunities.

OBJECTIVES: This study aimed to examine the training experiences of and determine capacity to train future Australian and New Zealand psychiatrists working in intellectual and developmental disability mental health. METHODS: Australian and New Zealand psychiatrists with expertise or interest in intellectual and developmental disability mental health completed an online survey detailing their training pathway, support for subspecialty training and capacity to provide rotations in this area. RESULTS: Psychiatrists (n=71) indicated the most common reasons they started practicing in intellectual and developmental disability mental health, and these included seeing people with intellectual or developmental disability in a service in which they worked, or personal experience with intellectual or developmental disability. Compared to those trained overseas, psychiatrists trained in Australia or New Zealand had lower ratings of the sufficiency of education received in intellectual and developmental disability mental health. Of the total respondents, 80% supported the development of subspecialty training. Augmentation of intellectual and developmental disability mental health content in the intermediate stage of training was also strongly supported. Participants identified 80 potential six-month training rotations in this area. CONCLUSIONS: Psychiatrists working in intellectual and developmental disability mental health strongly support enhancements to intellectual or developmental disability training, including the development of subspecialty training, and can identify potential training capacity if such subspecialty training was developed.

Clinical capacity of Australian and New Zealand psychiatrists who work with people with intellectual and developmental disabilities.

OBJECTIVE: To describe the characteristics and clinical capacity of Australian and New Zealand psychiatrists working in intellectual and developmental disability mental health (IDDMH). METHOD: Consultant psychiatrists (n=71) with an interest or expertise in IDDMH completed an online survey about their roles, experience and time spent in intellectual developmental disability (IDD)-related activities. RESULTS: Psychiatrists had worked in IDDMH for a median of 11.34 years and half (53.5%) reported expertise in the area. One-fifth of psychiatrists reported IDDMH as their main area of practice. The majority of respondents (85.1%) reported that they were working clinically with people with IDD. Respondents practicing clinically worked a median of 8 hours in clinical and 3 hours in non-clinical IDD-related work per week. CONCLUSIONS: Surveyed psychiatrists had considerable experience in IDDMH. However, their work in IDDMH represented a relatively small proportion of their overall work hours, and a minority of respondents were responsible for a large proportion of clinical work. Exploring ways to broaden capacity is crucial to ensuring the mental health needs of people with IDD are met.

Transition to adult mental health services for young people with an intellectual disability.

People with intellectual disabilities (ID) experience high rates of mental health problems, particularly during the period of transition to adulthood. It is therefore important that the transition from child- to adult-oriented health services for people with ID is well managed to ensure appropriate orientation to ongoing adult mental health care. The purpose of this paper is to summarise the impact and experience of transition to adult mental health care for people with ID and those who support them, as well as issues related to current policy and practice in this area. Several opportunities for improvement are identified in the broad areas of policy, service structure and organisation, research and workforce capacity. Enhancements in these areas will lead to improved outcomes for young people with ID transitioning from child- to adult-oriented mental health care.
