An observational study of the use of acute hospital care by people with intellectual disabilities in England

IDcare - a longitudinal register study of pre-pandemic and pandemic health care utilization and diagnostic profiles among people with intellectual disabilities in southern Sweden

The aim of the creation of this cohort was to investigate patterns of health and health care utilisation before and during the COVID-19 pandemic, overall and in relation to specific diagnoses, among people with intellectual disabilities (ID) compared to the general population. People living in Skåne, the southernmost region of Sweden, on 1st of January 2014 with at least one diagnosis of ID (ICD-10 codes F70-F79) or Down syndrome (DS; Q90), or support and/or services according to the LSS act comprised the ID cohort (n = 14 716). People living in the same family and/or household as a person in the ID cohort constituted the ID family cohort (n = 31 688), and those remaining comprised the general population cohort (gPop; n = 1 226 955). Data has been collected for all three cohorts from several national and regional registers. These include registers for health care (2014-2021), deaths (2014-2021), COVID-19-related health care (vaccinations, intensive care, palliative care, 2020-2021). The prevalence of ID was 1.2%. In the ID cohort, 77.9% had at least one measure of support, 5.8% at least one Q90-diagnosis and 63.8% had at least one F7-diagnosis (26.9% mild (F70), 7.4% moderate (F71), 2.8% severe (F72), 1.4% profound (F73), and 25.4% other/unknown (F78/F79)). Compared to the gPop there were more people in the younger age groups in the ID cohort. At this point, no additional collection of data will be carried out. However, there is a possibility to add data from the registers to include years after 2021 or from additional registers. Future publications will explore relevant research questions and report key findings in relation to health among people with ID. Future results will be used to inform policy and practice on people with ID.

"She just makes it easier…" The impact of having a dedicated nursing role in supporting people with intellectual disability when accessing acute hospitals, from the perspective of their support staff, the Irish context

Learning Disability Liaison Nurses have been shown to improve hospital experiences and this is an emerging role in Ireland. This research qualitatively explored the impact of a Clinical Nurse Specialist Acute Hospital Liaison from the perspective of staff in an intellectual disability community organisation. Participants identified significant challenges with supporting people attending hospitals including accessing and understanding information, anxieties and not being prepared for transitions through the hospital. The findings demonstrate the introduction of this role is a supportive, positive step with reports of improved information sharing, feeling better prepared and alleviating anxieties related to supporting someone in hospital. The findings clearly identify that this role has considerable benefits when set in a community organisation. This role has had a positive impact on service users and staff when interacting with hospitals, providing evidence of the value of this role in Ireland and also of they having a specialist qualification in the role.

Specialist intellectual disability liaison nurses in general hospitals in England: cohort study using a large mortality dataset

OBJECTIVE

Intellectual disability liaison nurses in general hospitals could enhance access to high-quality, adapted healthcare and improve outcomes. We aimed to explore associations between the input of intellectual disability liaison nurses and the quality of care in people with intellectual disability who are admitted to hospital.

DESIGN

Retrospective analysis of a national dataset of mortality reviews.

SETTING

General hospitals in England.

PARTICIPANTS

4742 adults with intellectual disability who died in hospital between 2016 and 2021 and whose deaths were reviewed as part of the Learning from Lives and Deaths mortality review programme.

OUTCOME MEASURES

We used logistic regression to compare the sociodemographic and clinical characteristics of those who did, and did not, receive input from an intellectual disability liaison nurse. We explored associations between liaison nurse input, care processes and overall quality of care.

RESULTS

One-third of people with intellectual disability who died in hospital in England between 2016 and 2021 had input from an intellectual disability liaison nurse. Intellectual disability liaison nurse input was not evenly distributed across England and was more common in those who died of cancer. Having an intellectual disability liaison nurse involved in an individual's care was associated with increased likelihood of reasonable adjustments being made to care (adjusted OR (aOR) 1.95, 95% CI 1.63 to 2.32) and of best practice being identified (aOR 1.37, 95% CI 1.17 to 1.60) but was not associated with a rating of overall quality of care received (aOR 0.94, 95% CI 0.78 to 1.12).

CONCLUSIONS

Intellectual disability liaison nurses see only a minority of people with intellectual disability who are admitted to hospital in England. Increasing the availability of intellectual disability liaison nurses could improve care for this disadvantaged group.

Being a child with intellectual disabilities in hospital: The need for an individualised approach to care

BACKGROUND

There is limited qualitative research focussed specifically on what it is like for children and young people with intellectual disabilities coming into hospital, with much of the evidence-base being about those with Autism Spectrum Condition or adults with intellectual disabilities.

AIM

To share rich detail of the emotional and physical impact on children and young people with intellectual disabilities of attending hospital, from their own and their parent's perspective.

METHODS

Talking Mats interviews, sticker survey and photography with children and young people with intellectual disabilities, and in-depth interviews, hospital diaries and photography with their parents.

RESULTS AND CONCLUSIONS

The multiple and compounding layers of complexity surrounding hospital care of children and young people with intellectual disabilities resulted in challenges associated with loss of familiarity and routine, undergoing procedures, managing sensory overload, managing pain and having a lack of safety awareness. An individualised approach to their care is needed.

Factors that affect GP referral of a child with intellectual disability for a mild illness: A discrete choice experiment

BACKGROUND

General practitioners (GP) report multiple challenges when treating individuals with intellectual disabilities which may influence referral rates. The study aimed to establish factors that influence GP's decision-making when referring a child with intellectual disabilities to the emergency department.

METHOD

Discrete choice experiments (DCEs) are increasingly used in health research to further understand complex decision making. A DCE was designed to assess the relative importance of factors that may influence a GP's (N = 157) decision to refer.

RESULTS

A random parameters model indicated that perceived limited parental capacity to manage an illness was the most important factor in the decision to refer a child to the ED, followed by a repeat visit, a referral request from the parent, and a Friday afternoon appointment.

CONCLUSION

Understanding the factors that influence referral is important for service improvement and to strengthen primary care provision for this population and their families.

Acute service and disability service providers experiences of joint working to improve health care experiences of people with an intellectual disability compared to non-joint working: A mixed-method systematic review

Persons with intellectual disabilities require frequent access to acute services. Many also access disability services within the community. Reports and enquiries have highlighted the sub-optimal healthcare provided to this group when accessing healthcare in acute services. Joint working between acute and disability services has been identified as a measure to improve healthcare for this group. A mixed method systematic review was undertaken to explore current evidence of joint working between both service providers. Twelve publications were included, and the data were analysed using thematic analysis. Confusion around responsibility and limited training in acute services prevented joint working from occurring. Information-sharing is pivotal in promoting joint-working, but measures which facilitated it were not always used. Albeit acute services demonstrated a strong commitment to deliver quality care to those with intellectual disabilities. Much of the available research captures the experiences of staff in acute services. There is a paucity of research available exploring experiences of disability service providers.

Recording of intellectual disability in general hospitals in England 2006-2019: Cohort study using linked datasets

BACKGROUND

Accurate recognition and recording of intellectual disability in those who are admitted to general hospitals is necessary for making reasonable adjustments, ensuring equitable access, and monitoring quality of care. In this study, we determined the rate of recording of intellectual disability in those with the condition who were admitted to hospital and factors associated with the condition being unrecorded.

METHODS AND FINDINGS

Retrospective cohort study using 2 linked datasets of routinely collected clinical data in England. We identified adults with diagnosed intellectual disability in a large secondary mental healthcare database and used general hospital records to investigate recording of intellectual disability when people were admitted to general hospitals between 2006 and 2019. Trends over time and factors associated with intellectual disability being unrecorded were investigated. We obtained data on 2,477 adults with intellectual disability who were admitted to a general hospital in England at least once during the study period (total number of admissions = 27,314; median number of admissions = 5). People with intellectual disability were accurately recorded as having the condition during 2.9% (95% CI 2.7% to 3.1%) of their admissions. Broadening the criteria to include a nonspecific code of learning difficulty increased recording to 27.7% (95% CI 27.2% to 28.3%) of all admissions. In analyses adjusted for age, sex, ethnicity, and socioeconomic deprivation, having a mild intellectual disability and being married were associated with increased odds of the intellectual disability being unrecorded in hospital records. We had no measure of quality of hospital care received and could not relate this to the presence or absence of a record of intellectual disability in the patient record.

CONCLUSIONS

Recognition and recording of intellectual disability in adults admitted to English general hospitals needs to be improved. Staff awareness training, screening at the point of admission, and data sharing between health and social care services could improve care for people with intellectual disability.

Top Ten Tips Palliative Care Clinicians Should Know About Navigating the Needs of Adults with Intellectual Disabilities

As many people with intellectual disabilities (ID) live longer, the need for access to quality palliative care (PC) rises. People with ID realize significant barriers and inequities in accessing health care and PC. The need for integrated disability and PC services with extensive collaboration is great. The following tips are for PC clinicians caring for people with ID, their families, caregivers, and the community. While patient-centered care is difficult to distill into "tips," this article, written by an interdisciplinary team of PC and ID specialists, offers resources and references to improve the care provided to people with ID and serious illnesses.

Healthcare utilization by children with neurological impairments and disabilities in rural Kenya: a retrospective cohort study combined with secondary analysis of audit data

Background: There is a paucity of data on healthcare utilization by children with neurological impairments (NI) in sub-Saharan Africa. We determined the rate, risk factors, causes, and outcomes of hospital admission and utilization patterns for rehabilitative care among children with NI in a defined rural area in Kenya. Methods: We designed two sub-studies to address the primary objectives. Firstly, we retrospectively observed 251 children aged 6–9 years with NI and 2162 age-matched controls to determine the rate, causes and outcomes of hospitalization in a local referral hospital. The two cohorts were identified from an epidemiological survey conducted in 2015 in a defined geographical area. Secondly, we reviewed hospital records to characterize utilization patterns for rehabilitative care. Results: Thirty-four in-patient admissions occurred in 8503 person-years of observation (PYO), yielding a crude rate of 400 admissions per 100 000 PYO (95% confidence interval (Cl): 286–560). The risk of admission was similar between cases and controls (rate ratio=0.70, 95%CI: 0.10–2.30, p = 0.31). The presence of electricity in the household was associated with reduced odds of admission (odds ratio=0.32, 95% Cl: 0.10–0.90, p < 0.01). Seizures and malaria were the main causes of admission. We confirmed six (0.3%) deaths during the follow-up period. Over 93% of outpatient paediatric visits for rehabilitative care were related to cerebral palsy and intellectual developmental delay. Health education (87%), rehabilitative exercises (79%) and assistive technology (64%) were the most common interventions. Conclusions: Surprisingly, the risk of hospitalization was not different between children with NI and those without, possibly because those with severe NI who died before this follow-up were under seclusion and restraint in the community. Evidence-based and tailored rehabilitative interventions are urgently required based on the existing secondary data.

Unscheduled healthcare for children with intellectual disabilities: A systematic scoping review

Background

The provision of unscheduled healthcare for children with intellectual disability is less researched than that focused on hospital settings or for adult services. The aim of the scoping review was to map the evidence base in this area and identify areas for future study.

Method

A five‐stage scoping review framework was adopted. CINAHL, PubMed, SCOPUS, PsycINFO, Embase, ProQuest Dissertation & Theses and Google Scholar were searched. Studies published in English after 1/1/2000 were considered eligible for inclusion.

Results

A total of 3158 titles and abstracts were screened, 137 full‐text articles were reviewed, and 25 papers met the inclusion criteria. Descriptive themes focused on inequities, needs and experiences of families', poor GP training, and limitations of existing evidence.

Conclusion

Describing trends in healthcare utilisation by this population is valuable for monitoring quality of healthcare, however, addressing observed inequities will require approaches that recognise specific issues within the health system that result in inequities.

Inequities in quality and safety outcomes for hospitalized children with intellectual disability

AIM

To investigate if there are inequities in quality and safety outcomes for children with intellectual disability admitted to two tertiary paediatric hospitals.

METHOD

A cross-sectional study of 1367 admissions for 1018 randomly selected patients admitted for more than 23 hours to one of two tertiary children's hospitals in Sydney, Australia (1st January-31st December 2017). Electronic medical records were manually interrogated to identify children with intellectual disability (including developmental delay). Data extracted included patient demographics, length of stay, number of admissions, and reported clinical incidents.

RESULTS

In total, 12.3% (n=125) of children admitted during the study period had intellectual disability, which represented 13.9% (n=190) of admissions. Sex and age at admission in children with and without intellectual disability were similar: 83 (43.7%) vs 507 (43.1%) females and 107 (56.3%) vs 670 (56.9%) males, p=0.875; median age 3 years (0-18y) vs 4 years (0-18y), p=0.122. Children with intellectual disability had significantly greater median length of stay (100.5h vs 79h, p<0.001) and cost of admission (A$11 596.38 vs A$8497.96) than their peers (p=0.001). Children with intellectual disability had more admissions with at least one incident compared to children without intellectual disability (14.7% vs 9.7%); this was not statistically significant (p=0.06).

INTERPRETATION

Children with intellectual disability experience inequitable quality and safety outcomes in hospital. Engaging children and families in clinical incident reporting may enhance understanding of safety risks for children with intellectual disability in hospital.

Codesigning patient experience measures for and with children and young people with intellectual disability: a study protocol

INTRODUCTION

Children and young people with intellectual disability represent one of the most vulnerable groups in healthcare, yet they remain under-represented in projects to design, develop and/or improve healthcare service delivery. Increasingly, healthcare services are using various codesign and coproduction methodologies to engage children and young people in service delivery improvements.

METHODS AND ANALYSIS

This study employs an inclusive approach to the study design and execution, including two co-researchers who are young people with intellectual disability on the project team. We will follow an adapted experience-based co-design methodology to enable children and young people with intellectual disability to participate fully in the co-design of a prototype tool for eliciting patient experience data from children and young people with intellectual disability in hospital.

ETHICS AND DISSEMINATION

This study was granted ethical approval on 1 February 2021 by the Sydney Children's Hospitals Network Human Research Ethics Committee, reference number 2020/ETH02898. Dissemination plan includes publications, doctoral thesis chapter, educational videos. A summary of findings will be shared with all participants and presented at the organisation quality and safety committee.

Consultation Needs for Young Adults with Intellectual and Developmental Disabilities Admitted to an Adult Tertiary Care Hospital: Implications for Inpatient Practice

BACKGROUND

Children with intellectual and developmental disabilities (IDD), particularly those with medical complexity, account for a large proportion of pediatric inpatients and are increasingly surviving to adulthood. However, few studies have evaluated the inpatient care of this population after transition to adult hospitals. This paper describes a Med-Peds Hospitalist service providing inpatient consultation for young adults with childhood conditions and offers a window into issues likely to be faced by young adults with IDD as they face increased admissions to adult hospitals.

METHODS

A single center retrospective chart review was performed of adults with intellectual and developmental disabilities referred to the Med-Peds consult service at a large urban adult academic medical center.

FINDINGS

The most common medical recommendations provided focused on diagnosis and management of gastrointestinal, neurologic, and respiratory issues. Coordination between pediatric and adult caregivers, disposition planning, communication and family support, and guidance on weight-based dosing were also commonly provided services.

DISCUSSION

Young adults with IDD face new challenges when admitted to adult hospitals. In this single-center study, several areas were identified where expert consultation could be helpful. The need for structured coordination of care for this vulnerable patient population was highlighted. Knowledgeable consultative services may be an effective intervention to address the unique needs of hospitalized young adults with IDD.

APPLICATION TO PRACTICE

Hospitals should consider structured inpatient programs, care-paths, or consultation from providers knowledgeable in the care of young adults with intellectual disabilities in order to improve the inpatient care of this population.

Differences in Hospital-Based Care for Patients With Intellectual and Developmental Disabilities

IMPORTANCE

The number of adults with intellectual and developmental disabilities (IDD) seeking treatment in non-IDD-specific health care settings is growing. Little is known about how adults with IDD use health care services in specialty settings, including occupational therapy services.

OBJECTIVE

To describe adults with IDD in hospitals and identify differences in utilization patterns compared with patients without IDD.

DESIGN

Descriptive and correlational designs were used.

PARTICIPANTS

Data were obtained from Vizient (Clinical Data Base/Resource Manager™), a national database of administrative discharge abstracts for adults admitted to hospitals for an orthopedic procedure. From this sample, subsamples of (1) patients diagnosed with IDD and (2) an age- and gender-matched sample of patients without IDD were identified.

RESULTS

The study cohort with IDD experienced longer lengths of stay, t(2821.5) = -14.2, p < .001; were more likely to have Medicare coverage, χ2(3, N = 8,472) = 1,170.38, p < .001; and were more commonly discharged to subacute or skilled nursing facilities, χ2(5, N = 8,472) = 1,033.60, p < .001. Differences in occupational therapy services were also noted.

CONCLUSIONS AND RELEVANCE

Despite similarities in orthopedic procedures, participants with IDD had different use patterns than those without IDD. Differences may be attributed to varying client factors and contexts. The results also indicate that practitioners in non-IDD-specific settings should expect to encounter clients with IDD. Occupational therapy practitioners have an opportunity to be leaders in adapting treatment protocols and providing education to caregivers and health care providers on behalf of people with IDD. What This Article Adds: This article provides novel information about a population that is known to experience disparities in health outcomes. It offers a basis on which future research can build to improve health care delivery and occupational therapy interventions to improve outcomes.

Linked data analysis of learning disability health checks and emergency hospital admissions in the Kent Integrated Dataset

BACKGROUND

People with learning disabilities have higher rates of admitted patient care than the general population. This study explored emergency hospital admissions during 2018/19 in association with learning disability health check recording in general practice within the Kent Integrated Dataset during 2016/17 to 2018/19.

METHODS

Multiple logistic regression evaluated the odds of emergency hospital admission by sex, age, deprivation, residence, risk score, long-term conditions, severe health needs and health check. During 2018/19, one or more emergency hospital admissions were recorded for 10.9% of the 5,759 persons recorded with learning disability.

RESULTS

There were lower odds of emergency hospital admission in persons having had learning disability health check in the past 3 years even after adjustment.

CONCLUSIONS

Comparison to nationally representative research suggests a consistent finding of benefit from learning disability health check on indicators of unplanned care use, supporting the view that learning disability health checks facilitate the addressing of key health needs.

Health inequities in unscheduled healthcare for children with intellectual disabilities in Ireland: a study protocol

Background: Health inequities for children with intellectual disabilities  are prevalent within different health systems, and children with intellectual disabilites  have shorter life expectancies than the general population, higher mortality rates before the age of 17 and have a greater risk of potentially preventable hospitalisations. A health systems approach to research in this area provides a useful means through which research can inform policy and practice to ensure people with intellectual disabilities receive equitable healthcare; however, there is a paucity of evidence regarding how to address differences that have been described in the literature to date. The overall aim of this research is to establish the extent of health inequities for children with intellectual disabilities  in Ireland compared to children without intellectual disabilities with respect to their utilisation of primary care and rates of hospitalisation, and to gain a better understanding of what influences utilisation of primary care and emergency department services in this population. Methods and analysis: The design of this research adopts a multi-methods approach: statistical analysis of health data to determine the extent of health inequities in relation to healthcare utilisation; discrete choice experiments to explore General Practitioners' decision making and parental preferences for optimal care; and concept mapping to develop consensus between stakeholders on how to address current healthcare inequities. Discussion: By applying a systems lens to the issue of health inequities for children with intellectual disabilities, the research hopes to gain a thorough understanding of the varying components that can contribute to the maintenance of such healthcare inequities. A key output from the research will be a set of feasible solutions and interventions that can address health inequities for this population.

A prospective study of hospital episodes of adults with intellectual disability

BACKGROUND

Previous research has shown poor hospital experiences and dire outcomes for people with intellectual disability. The main objective of this study was to prospectively track episodes for adults with intellectual disability (ID) in Australian hospitals, with a focus on indications of the quality of care provided.

METHODS

A prospective audit of hospital records over 35 months yielded quantitative data about patient characteristics, frequency and length of hospital episodes, diagnostic assessments and outcomes, post-emergency department (ED) destinations and post-discharge recommendations. Fifty participants were recruited largely by identification on hospital ED entry. An audit of patients' hospital records was conducted towards the end of hospital episodes, using a tool developed for the study.

RESULTS

Participants were mostly men (70%), aged 42.9 years on average, living mostly with family (46%) or in supported accommodation (44%). Of 157 recorded episodes, 96% started in ED,  85% required urgent or semi-urgent care and 62% were in the first 3 months of study participation. Average time in ED exceeded the 4-h national benchmark, met in 40% of episodes. One or more diagnostic assessments were conducted in 91% episodes and others in short stay units. Almost half (49%) resulted in a ward stay. With an extreme data point removed, <1-35 days were spent in wards. The most frequent diagnosis in 75% of episodes was for digestive problems, followed by nervous system problems then injuries. Median length of bed stays reflected data available for Australian refined diagnosis-related groups. High hospital re-presentations were found: for 67% of episodes in total, 26% (n = 12) of which were within 72 h and 59% (n = 23) within 30 days.

CONCLUSIONS

Adults with ID presented frequently to ED and often had lengthy stays. We found no indication of poor care practices in terms of hospital staff willingness to keep patients in ED and conduct of diagnostic assessments. Frequent re-presentations, however, indicated failed hospital care at some level.

An observational cohort study of numbers and causes of preventable general hospital admissions in people with and without intellectual disabilities in England

BACKGROUND

Hospital admissions for preventable reasons [ambulatory care sensitive (ACS) conditions] can indicate gaps in access to or quality of primary care. This paper seeks to document the numbers and causes of these admissions in England for people with intellectual disabilities (ID) compared with those without.

METHODS

Observational cohort study of number and duration of emergency admitted patient episodes for ACS conditions, overall and by cause, using the Clinical Practice Research Datalink GOLD primary care database and the linked Hospital Episode Statistics Admitted Patient Care dataset.

RESULTS

The study covered 5.2% of the population of England from April 2010 to March 2014 giving a total population base of 59 280 person-years for people with ID and 11 103 910 for people without identified ID. The rate of emergency admissions for ACS conditions for people with ID was 77.5 per 1000 person-years. As a crude comparison, this was 3.0 times the rate for those without ID, but standardising for the distinct demography of this group, the number of episodes was 4.8 times that expected if they had the same age-specific and sex-specific rates. Stay durations for these episodes were longer for both young-age and working-age people with ID. Overall people with ID used 399.8 bed-days per 1000 person-years. As a crude comparison, this is 2.8 times the figure for people without ID. Standardising for their age and sex profile, it is 5.4 times the number expected if they had the same age-specific and sex-specific rates. For patients with ID, 16.6% (one in six) of all admitted patient episodes and 24.3% (one in four) of in-patient care days for people with ID were for ACS conditions. Corresponding figures for those without ID were 8.3% (one in 12) and 14.4% (one in seven). The difference in rates between those with and without ID was most marked in people of working age. The three most common causes of emergency episodes for ACS conditions in people with ID were convulsions and epilepsy, influenza pneumonia and aspiration pneumonitis. Influenza pneumonia was also a common cause for people without ID. Episodes for convulsions and epilepsy and aspiration pneumonitis were specifically associated with people with ID.

CONCLUSIONS

Rates of hospital admissions for ACS conditions provide an important indicator of health literacy, basic self-care (or support by carers) and the accessibility of primary care. High rates are seen for some conditions specifically associated with premature death in people with ID. Local monitoring of these figures could be used to indicate the effectiveness of local primary health services in providing support to people with ID.

A qualitative study of nurses' perspectives of caring for children with intellectual disability and their families in a paediatric acute care setting

Children with intellectual disability (ID) experience chronic and pervasive limitations across intellectual and adaptive functioning. They are also at risk of developing co-morbidities. They are likely to be hospitalised more frequently and for longer periods of time than other children. The purpose of this study was to understand the experiences of nurses when caring for children and teenagers with ID in an acute paediatric hospital setting. The aim of the research was to inform future directions for the delivery of equitable and effective care for this vulnerable population. This study used a qualitative thematic analysis of individual interviews conducted with eight registered and enrolled nurses who provided care to children and adolescents with ID in an Australian paediatric acute hospital setting. Themes which emerged from this analysis were (1) Recognising similarities and managing differences; (2) Nurse-parent relationships; and (3) Caring for children with ID requires additional time. This study highlights that navigating care delivery and relationships when working with young people with ID and their caregivers in an acute care setting is complex. Nursing children with ID in hospital requires sophisticated skills. To ensure quality healthcare for patients with ID, a range of strategies are proposed.

Health and wellbeing of people with intellectual disability in New South Wales, Australia: a data linkage cohort

PURPOSE

People with intellectual disability (ID) experience high rates of physical and mental health problems, while access to appropriate healthcare is often poor. This cohort was established to develop an epidemiological profile related to the health, health service use, disability services, mortality and corrective services records of people with ID.

PARTICIPANTS

The cohort contains 92 542 people with ID (40% females) with a median age of 23 years (IQR: 12-43 years) and 2 004 475 people with a neuropsychiatric or developmental disorder diagnosis (50% females) with a median age of 51 years (IQR: 29-73 years) from New South Wales, Australia. The whole sample contains records for 2 097 017 individuals with most data sets spanning financial years 1 July 2001 to 30 June 2016. A wide range of data from linked population data sets are included in the areas of disability, health, corrective services and targeted specialist support services in public schools, Public Guardian and Ombudsman services.

FINDINGS TO DATE

This study includes one of the largest cohorts of people with ID internationally. Our data have shown that the presence of ID is significantly associated with emergency department presentations and psychiatric readmissions after the first psychiatric admission based on a subcohort of people with a psychiatric admission. Adults with ID experience premature mortality and over-representation of potentially avoidable deaths compared with the general population.

FUTURE PLANS

Within the health service system, we will examine different components, that is, inpatient, emergency adult services, children and younger people services and costs associated with healthcare as well as mortality, cause and predictors of death. The neuropsychiatric and developmental disorders comparison cohort allows comparisons of the physical health, mental health and service use profiles of people with ID and those with other neuropsychiatric disorders.
