Systematic Reviews of the Health or Health care of People with Intellectual Disabilities: A Systematic Review to Identify Gaps in the Evidence Base

Population Level Mental Health Diagnoses for Youth with Intellectual/Developmental Disabilities Compared to Youth without Intellectual/Developmental Disabilities

There is evidence in the literature that youth with intellectual/developmental disabilities (IDD) experience mental health issues to a greater extent compared to youth without IDD. In addition, transition from pediatric to adult services may be a period of increased anxiety and mental health problems for these youth. This study used a retrospective cohort design using population level administrative health data to compare mental health diagnoses between youth with IDD and youth without IDD; particularly examining the period when youth transition from pediatric health services to adult health services. In addition, this study compared the mental health of youth with various types of IDD (Down syndrome, autism, fetal alcohol syndrome and other rarer diagnoses). Results showed that at the population level youth with IDD have greater odds of anxiety/depression or psychotic illness than youth without IDD. Adjusted odds of anxiety/depression or psychotic illness also varied with age, income level, sex, and type of IDD. Youth with fetal alcohol syndrome had the greatest odds of both anxiety/depression and a psychotic illness. Odds of anxiety/depression increased from age 15-19 years old. Odds of a psychotic illness increased from age 15 to age 24 years old.

Chewing difficulties, oral health, and nutritional status in adults with intellectual disabilities: A cross-sectional study

BACKGROUND

Chewing difficulty, poor oral health, inadequate and imbalanced nutrition are serious health problems in individuals with intellectual disabilities. The participants' chewing abilities, oral health and nutritional status were analysed in this study.

METHODS

Forty-five adult participants with intellectual disabilities were included. Anthropometric measurements, oral health assessments, chewing ability evaluations and dietary intake analyses were conducted.

RESULTS

A 56.8% of the participants were classified as overweight or obese. Teeth grinding was reported in 33.3% of the participants, while 40.0% experienced drooling. All participants with Down syndrome and 58.6% of the participants with developmental delay had chewing difficulties. Inadequate nutrient intake was observed and the fibre, vitamins B1, B3, B9, sodium, phosphorus and iron intakes were significantly lower than reference values in those with chewing difficulty (p < .05).

CONCLUSIONS

Chewing difficulties were associated with lower intake of certain nutrients, highlighting the importance of addressing oral health and dietary counselling in this population.

Trauma treatment using Narrative Exposure Therapy adapted to persons with intellectual disabilities or severe chronic mental disorders - a randomised controlled pilot study with an embedded observational study

BACKGROUND

Despite an increased likelihood of experiencing traumatic events and increased vulnerability, there are only few publications on trauma therapy for persons with intellectual disabilities (IDs). This pilot study for the first time investigates the feasibility and effectiveness of Narrative Exposure Therapy (NET) within this target group modified by Plain Language.

METHODS

A group of n = 10 participants with ID dual diagnoses and another group of n = 5 participants with severe and chronic mental disorders were separately stratified and randomised, then forming together an intervention group (n = 7) and a waiting list control group (n = 8). All participants were treated with NET attuned to their communication abilities by using Plain Language. Primary outcome was the post-traumatic stress measured with the Post-Traumatic Symptom Scale-10 before and after the intervention. In addition, the Adverse Childhood Experience Index was used for diagnostic purposes. Data were analysed using t-test for repeated measures and analysis of covariance.

RESULTS

Narrative Exposure Therapy and the randomised controlled trial study proved to be successfully conductible with participants with IDs in a congregated residential service. Although the corresponding effect size was high (partial eta square = 0.188), the between-group difference was not significant (P = 0.12). Analysis of the observational study resulted in a highly significant improvement for participants with IDs (P < 0.001; Hedges' g = 2.36) and in a significant improvement in participants with severe and chronic mental disorders (P < 0.013; Hedges' g = 1.52). Additionally, the participants with IDs show a significantly better reduction of symptom burden (P = 0.03; partial eta square = 0.327).

CONCLUSIONS

The results provide a first evidence for a possible and successful implementation of NET modified in Plain Language for persons with IDs and complex mental health support needs. Completeness in responding to the items of Post-Traumatic Symptom Scale-10 and Adverse Childhood Experience Index indicates the suitability of these instruments for both groups of participants. Although the group difference in the randomised controlled trial failed to achieve statistical significance mainly due to the small sample size, the results of the embedded observational study are promising for the conduct of further studies with the modified NET.

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.

Declining high-impact clinical publication rate: A potential contributor to health disparities among persons with developmental and intellectual disabilities

Background

Persons with intellectual and developmental disabilities (IDD) suffer from stark, well-documented health and healthcare disparities, despite data indicating that the majority see a healthcare provider at least annually. Multiple surveys have indicated that over 90% of physicians feel they have inadequate knowledge and skill in caring for those with IDD. This has been recognized as a key barrier to health equity.

Objective

To evaluate the content of high-impact clinical literature for a potential cause of clinician knowledge deficits.

Methods

We performed a bibliometric analysis of publications within major, high-impact general, and specialty clinical journals from 1946 to 2020 to determine the relative frequency of publications regarding IDD and publication rate.

Results

We observed a significant decline in articles regarding IDD over the past 20 years within high-impact general medical journals, and a significant decline over the past 15 years within high-impact, specialty society-published journals of Psychiatry, Psychology, and Neurology. Furthermore, we observed that high-impact general medical journals devoted a significantly smaller proportion of publication space to articles regarding IDD than they did for conditions with similar prevalence such as HIV/AIDS, breast cancer, and drug abuse.

Conclusion

The declining rate and low frequency of clinical publications regarding IDD within the major, respected clinical literature may be contributing to physicians' ability to source evidence-based information, thereby impacting perceptions of skill and knowledge deficits, and therefore may be contributing to healthcare disparities in this population. Well-designed clinical studies that engage persons with IDD may lead to an evidence base within the clinical literature that will improve physician confidence and care quality.

Adults with intellectual disabilities' satisfaction regarding their hospitalization: A correlational descriptive study

When hospitalized, adults with intellectual disabilities are more anxious and have more unmet needs than the general population. Despite these problems, studies report contradictory results about their satisfaction with hospitalization. The aim of this study was to determine the level of satisfaction of adults with intellectual disabilities regarding their hospital care and the factors associated with satisfaction. An analysis of the Patient Satisfaction Scale (PSS) and Cognitive Appraisal of Health Scale (CAHS) instruments completed by adults with intellectual disabilities, or their caregivers, after hospitalization was done. The 32 participants' mean PSS score was 3.6/5, with means of 13.3/25 and 8.7/25 on the CAHS' 'harm/loss' dimension and 'challenge' dimension, respectively. None of the factors studied was associated with the total PSS score. Adults with intellectual disabilities were not fully satisfied with their hospital care, experiencing challenges and losses. These findings call for a rethink of the care provided to this population.

Barriers and facilitators to participation in everyday activities for children with intellectual disabilities in China

BACKGROUND

Children with intellectual disabilities (IDs) are vulnerable and participate less in everyday activities compared to their peers with typical development. This study aimed to identify barriers and facilitators related to the participation in everyday activities of children with IDs in China.

METHODS

Twenty semi-structured interviews were conducted with primary caregivers of children with IDs from special schools in Tianjin, China. The data were transcribed and analysed using inductive qualitative content analysis.

RESULTS

Four categories of barriers to participation in everyday activities for children with IDs were identified: insufficient knowledge, attitudes and skills in primary caregivers; ID-related characteristics of children; stigma and Chinese culture; and lack of support from society. Four categories describing facilitators of participation in everyday activities for children with IDs were also identified: the optimistic attitude of the primary caregiver; adequate family support; active environment in school and policy; and attractive characteristics of children with IDs.

CONCLUSIONS

The findings in this study add knowledge on important barriers and facilitators affecting the participation of children with IDs in everyday activities in China. The primary caregivers' voices need to be heard by government and society. Appropriate and effective changes in family-oriented services and the legal, social, political and economic context of the child welfare management system for the scale-up of improving participation should be implemented for children with IDs.

Barriers to the access of people with disabilities to health services: a scoping review

OBJECTIVE

To analyze the scientific evidence regarding barriers to the access of people with disabilities to health services.

METHODS

A scoping review was carried out from the main question: "What are the main barriers that people with disabilities face in accessing health services?" The articles were surveyed in July 2019 in six scientific literature databases. Of the 1,155 documents identified in the searches, after selection by title and abstract, 170 publications were read in full and, thus, 96 articles were included and categorized according to the theoretical framework.

RESULTS

The main barriers indicated by the users of the service were: communication failure between professionals and patient/caregiver; financial limitations; attitudinal/behavioral issues; scarce service provision; organizational and transport barriers. The main barriers presented by service providers were: lack of training to professionals; failure of the health system; physical barriers; lack of resources/technology; and language barriers.

CONCLUSIONS

It was evident that people with disabilities face several barriers when trying to access the health services they need and that users and health professionals have distinct and complementary views on difficulties.

Motives and strategies of CEOs for stimulating sharing and application of knowledge in the care and support for people with intellectual disabilities

Purpose

Within intellectual disability care organizations (IDCOs), it is vital that professionals share and apply knowledge to improve the quality of care for their service users. Given that chief executive officers (CEOs) play a pivotal role in enabling these processes, this paper aims to investigate both the underlying motives and strategies behind CEOs’ organizational knowledge leadership and their contribution to improving these knowledge processes.

Design/methodology/approach

In this exploratory qualitative study, 11 CEOs from IDCOs in the Netherlands who are actively involved in knowledge management within their organizations were interviewed. An inductive thematic analysis was conducted.

Findings

CEOs’ motives for stimulating knowledge processes among professionals in IDCOs arise from the internal (e.g. the CEOs themselves) and external (e.g. policy) contexts. This study also identified four strategies adopted by CEOs to stimulate sharing and application of knowledge: providing organizational conditions for effective knowledge processes; focused attention on talent development; acknowledgment and deployment of knowledge holders; and knowledge-driven participation in collaborative partnerships. These strategies are used in combination and have been shown to reinforce one another.

Practical implications

An overview of strategies for stimulating knowledge processes is now available.

Originality/value

The results display the leadership of CEOs in knowledge strategies. Insights into their perceptions and values are provided while elaborating on their motives to take this role.

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.

Mortality rate and cause among people with intellectual disabilities in South Korea: A nationwide representative cross-sectional study from 2015 to 2019

People with intellectual disabilities (ID) age faster and have a higher prevalence of degenerative diseases. The aim of this study was to identify the patterns/ causes of death among people with ID. We conducted a nationwide, retrospective, cross-sectional study of people with ID in South Korea. The database was compiled by merging data of people registered with ID, based on the 2015-2019 Standards from the Ministry of Health and Welfare, with the cause of death data published by the Korea National Statistical Office. The International Classification of Diseases-10 (ICD-10) was used to categorize causes of death. The mortality and standardized mortality rates were calculated and major causes of death were analyzed. As of 2019, the mortality rate of people with ID in South Korea was 784.6. The rate showed an irregular pattern, increasing or decreasing year by year (increasing from 725 in 2015 to 834 in 2018). The mortality rate of people with ID was approximately 1.4 times higher than the general population; the standardized mortality rate was 3.2 times higher. The main causes of death (48%) in people with ID were, in order of prevalence, circulatory diseases (cerebrovascular disease), neoplasms (malignant neoplasms of the digestive system), and diseases of the respiratory system (pneumonia). The leading causes of death (>60%) in the general population were, in order of prevalence, neoplasms, diseases of the circulatory system, and respiratory system diseases. An accurate understanding of the causes of death of people with ID is important to promote the development and application of health promotion programs and management thereof.

What Are the Psycho-Social and Information Needs of Adolescents and Young Adults Cancer Care Consumers with Intellectual Disability? A Systematic Review of Evidence with Recommendations for Future Research and Practice

People with intellectual disability have unmet health needs and experience health inequalities. There is limited literature regarding cancer care for children, adolescents, and young adults (AYA) with intellectual disability despite rising cancer incidence rates in this population. This systematic review aimed to identify the psycho-social and information support needs of AYA cancer care consumers with intellectual disability to generate recommendations for future research and cancer care service delivery enhancement. We searched eight databases yielding 798 articles. Following abstract and full-text review, we identified 12 articles meeting our inclusion criteria. Our three themes related to communication and accessible information; supports and system navigation, cancer service provider training, and reasonable adjustments. There was a lack of user-friendly, accessible information about cancer and screening programs available. Both paid and family carers are critical in accessing cancer supports, services, and screening programs for AYA with intellectual disability. Ongoing training should be provided to healthcare professionals regarding the importance of care screening for AYAs with intellectual disability. This review recommends that AYA with intellectual disability and their family carers be involved in developing tailored cancer services. This should focus on enabling inclusive screening programs, accessible consent, and challenging the enduring paternalism of support services via training and appropriate communication tools.

A scoping review documenting cancer outcomes and inequities for adults living with intellectual and/or developmental disabilities

INTRODUCTION

Emerging evidence suggests adults with intellectual and/or developmental disabilities (IDD) may be at risk of inequities in cancer experiences and outcomes. Individuals with IDD may experience multiple barriers that could worsen outcomes and experience. These barriers may be connected to features of IDD or the healthcare system overall. Future research and program planning to support adults with IDD and cancer must be informed by evidence that acknowledges potential disparities, underlying determinants, and knowledge deficits.

OBJECTIVE

We conducted a scoping review to systematically map the evidence describing and comparing cancer-related outcomes along the cancer continuum from risk to mortality for adults with IDD. We identified specific factors observed to influence those outcomes.

METHODS

We followed the expanded Arksey & O'Malley framework for conducting the scoping review. We searched for literature in PubMed and Embase databases. We abstracted cancer-related data, IDD-related data, and data related to physical and social determinants of health.

RESULTS

Of the 2796 studies retrieved, 38 were included for review. Most studies focused on screening outcomes and experiences. Studies reported that adults with IDD experienced inequities at various points along the cancer continuum. Numerous social and physical determinants of health influenced the experiences and outcomes of adults with IDD.

CONCLUSION

This scoping review identified significant gaps in the literature. Of note was the focus on cancer screening and lack of attention to larger systems of oppression that may influence poor cancer experiences and outcomes for adults with IDD. There is strong need to improve both quality and quantity of research in this area.

Prevalence and incidence of physical health conditions in people with intellectual disability - a systematic review

OBJECTIVE

To synthesize evidence on the prevalence and incidence of physical health conditions in people with intellectual disability (ID).

METHODS

We searched Medline, PsycInfo, and Embase for eligible studies and extracted the prevalence, incidence, and risk of physical health conditions in people with ID.

RESULTS

Of 131 eligible studies, we synthesized results from 77 moderate- to high-quality studies, which was mainly limited to high-income countries. The highest prevalence estimates were observed for epilepsy, ear and eye disorders, cerebral palsy, obesity, osteoporosis, congenital heart defects, and thyroid disorders. Some conditions were more common in people with a genetic syndrome. Compared with the general population, many health conditions occur more frequently among people with ID, including asthma and diabetes, while some conditions such as non-congenital circulatory diseases and solid cancers occur at the same or lower rate. The latter associations may reflect under-detection.

CONCLUSIONS

People with ID have a health profile more complex than previously known. There is a pressing need for targeted, evidence-informed population health initiatives including preventative programs for this population.

The Oral Status Survey Tool: construction, validity, reliability and feasibility among people with mild and moderate intellectual disabilities

BACKGROUND

A lack of robust data about the oral health of people with intellectual disabilities (IDs) contributes to health disparities. Appropriate research tools are therefore needed. This study reports the construction and evaluation of the Oral Status Survey Tool (OSST), designed to be administered with people with disabilities by non-dental personnel.

METHOD

Oral Status Survey Tool construction and evaluation was achieved adopting a non-clinical construction and content validation phase and a clinical phase to test concurrent validity, reliability and feasibility. Final refinements were also made.

RESULTS

The OSST conceptual framework covered oral function (tooth count, denture wear and opposing pairs of teeth) and oral disease/treatment need (soft tissue status, oral cleanliness, gum condition, carious teeth and oral pain). A systematic literature review identified no existing suitable indices. Candidate items were identified and validated by experts generating content validation ratios. This framework was modified later to expand the function construct. In the initial clinical phase, 49 out of 60 participants underwent examination with OSST and standard dental assessments. All had mild to moderate IDs. Mean age was 43 years (SD = 16), and mean number of teeth was 22.1 (SD = 8.6). Data collectors included two dentists and three non-dentists. Later, a further 17 adults (nine female and eight male) with mild/moderate IDs were included for refinement. At this stage, data collectors included two dentists and five non-dentists. Concurrent validity was established for tooth count [intraclass correlation coefficient = 0.99 (95% confidence interval, CI: 0.99-0.99)], carious teeth [Gwet's AC2 = 0.94 (95% CI: 0.89-0.99)] and gum condition [Gwet's AC1 = 0.84 (95% CI: 0.64-1)]. For all final OSST items, inter-rater reliability ranged from moderate to very good; median test-retest reliability ranged from moderate to good. Acceptability was demonstrated for data collectors and participants. Mean time to complete the OSST was 7 min.

CONCLUSIONS

The OSST is a novel tool that can record a range of clinical oral features including tooth count, denture wear, occluding pairs of teeth and functional dentition, oral cleanliness, gum condition, carious cavitation and oral pain that will be useful within health surveys of people with mild-moderate IDs and similarly neglected populations. The tool demonstrates promising attributes and acceptability. From this study, the OSST appears to be a robust tool that can be incorporated into general data collection for people with mild-moderate IDs and similar populations. A key feature is that it can be administered by well-trained non-dentists.

Changes over time in the management of long-term conditions in primary health care for adults with intellectual disabilities, and the healthcare inequality gap

BACKGROUND

Quality of primary healthcare impacts on health outcomes. This study aimed to quantify trends in good practice and the healthcare inequalities gap.

METHOD

Indicators of best-practice management of long-term conditions and health promotion were extracted from primary healthcare records on 721 adults with intellectual disabilities in 2007-2010, and 3638 in 2014. They were compared over time, and with the general population in 2014, using Fisher's Exact test and ordinal regression.

RESULTS

Management improved for adults with intellectual disabilities over time (OR = 5.32; CI = 2.69-10.55), but not for the general population (OR = 0.74; CI = 0.34-1.64). However, it remained poorer, but to a lesser extent, compared with the general population (OR = 0.38; CI = 0.20-0.73 in 2014, and OR = 0.05; CI = 0.02-0.12 in 2007-2010). In 2014, health care was comparable to the general population on 49/78 (62.8%) indicators.

CONCLUSIONS

The extent of the healthcare inequality gap reduced over this period, but remaining inequalities highlight that further action is still necessary.

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 nurses' ethical commitment to people with intellectual and developmental disabilities

Aim: This article explores the issues of knowledge deficits of healthcare professionals in meeting the needs of people with IDD throughout the life span, and to identify factors that contribute to these deficits. Although statistics vary due to census results and the presence of a "hidden population," approximately 1%-3% of the global population identify as living with an intellectual or developmental disability. People with intellectual or developmental disability experience health inequities and confront multiple barriers in society, often related to the stigma of intellectual or developmental disability. Disparities in care and service are attributed to a lack of knowledge and understanding among healthcare providers about people with intellectual or developmental disability, despite their increased risk for chronic health problems. The near absence of educational programs in nursing both nationally and internationally contributes to this significant knowledge deficit. In addition, ethical considerations between paternalistic beneficence and idealized autonomy have resulted in a lack of clear direction in working with a population that is often ignored or exploited. Nurses who view people with intellectual or developmental disability as vulnerable without assessing or acknowledging their capabilities may err toward paternalism in an effort to "first do no harm." Likewise, nurses who fail to recognize the challenges and limitations faced by people with intellectual or developmental disability may not provide sufficient protections for a vulnerable person. People with intellectual or developmental disability are not binary, but rather complex individuals with a myriad of presentations. This article seeks to encourage a well-informed model of nursing care. Through an ethical lens, this article explores the nurse's ethical commitments in cases of victimization, access to care, decision making, and the provision of optimal end-of-life care for people with intellectual or developmental disability.

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

Background: Health inequities for children with intellectual disabilities (ID) are prevalent within different health systems, and children with ID 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 ID receive equitable healthcare; however, there is a paucity of evidence regarding how to address differences that have been described in the literature to date.

Scoping review protocol documenting cancer outcomes and inequalities for adults living with intellectual and/or developmental disabilities

INTRODUCTION

There is increasing attention on the cancer burden for adults with intellectual and developmental disabilities (IDD). Emerging evidence suggests there are differences in cancer experiences and outcomes for individuals living with IDD, from risk through survivorship. These differences may be attributed to features of the IDD, such as cognitive deficits and communication, as well as social determinants of health-like lower education levels and ableism. However, there is no comprehensive overview of the literature quantifying these potential disparities and describing the influencing factors. In this paper, we describe a scoping review protocol to systematically review published literature on cancer for adults with IDD. The purpose of this review is to identify differences in cancer risk, stage at diagnosis, treatment and survival along the cancer continuum for adults with IDD and outline potential contributing factors creating these disparities.

METHODS AND ANALYSIS

We will follow Arksey and O'Malley's expanded framework for scoping reviews to conduct this review. We will systematically search electronic databases for peer-reviewed, published journal articles to identify appropriate studies in collaboration with a health science librarian. Two reviewers will independently review titles and abstracts followed by a full-text review to determine whether it meets inclusion criteria. A data chart for collecting and sorting information will be developed in consultation with the team. Results will be collated and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews: PRISMA-Scoping Reviews. Extracted information will be summarised quantitatively and qualitatively to meet review objectives.

ETHICS AND DISSEMINATION

This scoping review will employ a methodology to identify literature related to cancer outcomes and experiences for adults with IDD. Results will be disseminated to relevant stakeholders who care for and support individuals with IDD at local, provincial and national levels and through publishing findings. By highlighting the disparities in the cancer system and gaps in the research, this scoping review can provide direction for future action.

Rehabilitation service utilisation among adults with intellectual disabilities: Trends and socioeconomic disparities in China

BACKGROUND

Intellectual disabilities (IDs) have become a public health concern worldwide, but few studies on rehabilitation service utilisation in this population were conducted in developing countries. We aimed to examine trends and socioeconomic disparities in the utilisation of rehabilitation services among adults with IDs in China.

METHODS

We obtained data from a population-based survey by using a multistage, randomised, cluster sampling process to ascertain adults with IDs in 2006 and a selected subsample for follow-up surveys during 2007-2013. Psychiatrists ascertained individuals with IDs ascertained by intelligence quotient score under 70, deficits in two or more adaptive behaviours and age of onset under 18 years.

RESULTS

Overall, the utilisation rate of rehabilitation services significantly increased from 10.1% in 2007 to 33.7% in 2013, with an annual average percentage growth of 34.3% when adjusting for multiple confounders. The mounting trends remained significant in all socioeconomic groups. The growth rates among lower socioeconomic participants were much higher than those among higher socioeconomic participants, and the strength in the association between socioeconomic position (education and region) and rehabilitation service utilisation declined in 2007-2013.

CONCLUSIONS

This study found an upward trend in rehabilitation service utilisation in Chinese adults with IDs during 2007-2013, and socioeconomic disparities in rehabilitation service use in this population showed a downward trend over time.

How to improve sharing and application of knowledge in care and support for people with intellectual disabilities? A systematic review

BACKGROUND

To optimise care and support for people with intellectual disabilities (ID), sharing and application of knowledge is a precondition. In healthcare in general, there is a body of knowledge on bridging the 'know-do-gap'. However, it is not known to what extent the identified barriers and facilitators to knowledge sharing and application also hold for the care and support of people with ID, due to its specific characteristics including long-term care. Therefore, we conducted a systematic review to identify which organisational factors are enabling and/or disabling in stimulating the sharing and application of knowledge in the care and support of people with ID.

METHOD

A systematic review was conducted using five electronic databases of relevant articles published in English between January 2000 and December 2015. During each phase of selection and analysis a minimum of two independent reviewers assessed all articles according to PRISMA guidelines.

RESULTS

In total 2,256 articles were retrieved, of which 19 articles met our inclusion criteria. All organisational factors retrieved from these articles were categorised into three main clusters: (1) characteristics of the intervention (factors related to the tools and processes by which the method was implemented); (2) factors related to people (both at an individual and group level); and, (3) factors related to the organisational context (both material factors (office arrangements and ICT system, resources, time and organisation) and immaterial factors (training, staff, size of team)).

CONCLUSION

Overall analyses of the retrieved factors suggest that they are related to each other through the preconditional role of management (i.e., practice leadership) and the key role of professionals (i.e. (in)ability to fulfill new roles).

A systematic review of the methodological and practical challenges of undertaking randomised-controlled trials with cognitive disability populations

Approximately 10% of the world's population have a cognitive disability. Cognitive disabilities can have a profound impact on a person's social, cognitive or mental functioning, requiring high levels of costly health and social support. Therefore, it is imperative that interventions and services received are based upon a sound evidence-base. For many interventions for this population, this evidence-base does not yet exist and there is a need for more Randomised Controlled Trials (RCTs). The process of conducting RCTs with disabled populations is fraught with methodological challenges. We need a better understanding of these methodological barriers if the evidence-bases are to be developed. The purpose of this study was to explore the methodological and practical barriers to conducting trials with adults with cognitive disabilities. As a case example, the literature regarding RCTs for people with intellectual disabilities (ID) was used to highlight these pertinent issues. A systematic literature review was conducted of RCTs with adults with ID, published from 2000 to 2017. A total of 53 papers met the inclusion criteria and were reviewed. Some of the barriers reported were specific to the RCT methodology and others specific to people with disabilities. Notable barriers included; difficulties recruiting; obtaining consent; resistance to the use of control groups; engaging with carers, staff and stakeholders; the need to adapt interventions and resources to be disability-accessible; and staff turnover. Conducting RCTs with people with cognitive disabilities can be challenging, however with reasonable adjustments, many of these barriers can be overcome. Researchers are not maximising the sharing of their experience-base. As a result, the development of evidence-bases remains slow and the health inequities of people with disabilities will continue to grow. The importance of the MRC guidelines on process evaluations, together with implications for the dissemination of 'evidence-base' and 'experience-base' are discussed.

Prevalence of physical conditions and multimorbidity in a cohort of adults with intellectual disabilities with and without Down syndrome: cross-sectional study

OBJECTIVES

To investigate the prevalence of multimorbidity in adults with intellectual disabilities with and without Down syndrome.

DESIGN

Large, population-based cross-sectional study.

SETTING

The geographical area of one Health Board, Scotland.

PARTICIPANTS

All adults (aged 16+ years) known to general practitioners to have intellectual disabilities and adults receiving services provided or paid by intellectual disabilities health or social work services. 1023/1562 potential participants took part (65.5%); 562 (54.9%) men and 461 (45.1%) women, aged 43.9 years (16-83 years). 186 had Down syndrome and 837 did not.

MAIN OUTCOME MEASURES

The prevalence of International Statistical Classification of Diseases, 10th revision, physical health conditions and multimorbidity detected at a comprehensive health assessment.

RESULTS

The mean number of physical health conditions/participant was 11.04, and 98.7% had multimorbidity. The most prevalent conditions are painful and/or disabling and, in some cases, life threatening. The five most prevalent were visual impairment, obesity, epilepsy, constipation and ataxic/gait disorders. The pattern of multimorbidity differs from that seen in the general population and is spread across the entire adult life course. The extent of multimorbidity in the adults with Down syndrome was similar to that of the adults without Down syndrome, while the prevalence of individual conditions differed.

CONCLUSIONS

This robustly designed study with a large population found an extremely high prevalence of multimorbidity in adults with intellectual disabilities across the entire adult life course. This increases complexity of medical management that secondary healthcare services and medical education are not yet geared towards, as these tend to focus on single conditions. This is in addition to complexity due to limitations in communication and understanding. As the physical conditions within their multimorbidity also differ from that seen in the older general population, urgent attention is needed to develop the care pathways and guidelines that are required to inform and so improve their healthcare.

Twelve tips for teaching child development and disability to medical students

Child development is a marker of well-being in childhood and recognition of developmental delay allows timely investigation and intervention for children with developmental disabilities. Despite this, child development and disabilities are not given emphasis in the medical curriculum. This under representation of teaching combined with the stigma associated with disabilities contributes to the sub-optimal health care of people with disabilities. As well as, addressing the stigma of disability a medical undergraduate curriculum should include: the key concepts of child development; the clinical presentation of the most common developmental disabilities; developmental history taking and the infant neurodevelopmental examination. The following twelve tips provide practical advice about how to teach this knowledge and these skills during medical training.

Mortality patterns and risk among older men and women with intellectual disability: a Swedish national retrospective cohort study

Background

Sweden has closed all institutions and imposed legislation to ensure service and support for individuals with intellectual disability (ID). Understanding mortality among older individuals with ID is essential to inform development of health promotion and disease control strategies. We investigated patterns and risk of mortality among older adults with ID in Sweden.

Methods

This retrospective cohort study compared older adults aged 55 years and older with ID with a control population. Participants were followed during 2002–2015 or death, and censored if they moved out of Sweden. Individuals with ID were identified from two national registers: one covering all specialist health-care visits (out-patient visits and hospitalisation) and the other covering people accessing social/support services. Individuals with ID (n = 15,289) were matched with a control population by sex, birth year, and year of first hospitalisation/out-patient visit/access to LSS services. Cause-of-death data were recorded using International Classification of Diseases, Tenth Revision. Cox proportional hazards regression were conducted to assess if overall and cause-specific mortality rate among individuals with ID was higher than in the Swedish population.

Results

The overall mortality rate among individuals with ID was 2483 per 100,000 people compared with 810 in the control population. Among those who died, more individuals with ID were younger than 75 years and unmarried. Leading causes of death among individuals with ID were circulatory diseases (34%), respiratory diseases (17%) and neoplasms (15%). Leading causes of death in a sub-sample with Down syndrome (DS) were respiratory diseases (37%), circulatory diseases (26%) and mental/behavioural disorders (11%). Epilepsy and pneumonitis were more common among individuals with ID than controls. Alzheimer’s disease was common in the control population and individuals with DS, but not among those with ID when DS was excluded. Individuals with ID had a higher overall mortality risk (hazard ratio [HR] 4.1, 95% confidence interval [CI] 4.0–4.3) and respiratory disease death risk (HR 12.5, 95% CI 10.9–14.2) than controls.

Conclusion

Older adults with ID in Sweden carry a higher mortality risk compared with the general population, mainly attributable to respiratory, nervous and circulatory diseases. Care for this group, particularly during the terminal stage of illness, needs to be tailored based on understanding of their main health problem.

Prevalence and general health status of people with intellectual disabilities in Scotland: a total population study

Background

Prevalence of intellectual disabilities varies considerably between studies. People with intellectual disabilities experience health inequalities, but most studies comprise small or incomplete populations. We investigated in a whole country population the (1) prevalence of intellectual disabilities and (2) general health status compared with the general population.

Method

Data were from Scotland’s Census, 2011. We calculated the prevalence of intellectual disabilities, reported general health status of people with and without intellectual disabilities and the extent of health-related limitations to daily activities. We conducted logistic regressions to determine the ORs of intellectual disabilities predicting poor health and associations with age and gender.

Results

Of Scotland’s 5 295 403 population, 26 349 (0.5%) had intellectual disabilities; 15 149 (57.5%) were males and 11 200 (42.5%) were females; 5234 (0.6%) were children/youth (0–15) and 21 115 (0.5%) were adults (16–75+ years). Identification of intellectual disabilities rises until age 5 years, with a further small rise by age 9 years. Children and adults with intellectual disabilities reported more poor health (47.9% and 40.3%) than the general population (2.1% and 13.8%) and were more limited in activities by their health. Intellectual disabilities had an OR of 43.2 (95% CI 40.8 to 45.7) in predicting poor health; the influence of increasing age on poor health was markedly interacted by presence of intellectual disabilities, likely to be due to a ‘healthy survivor’ effect within the intellectual disabilities population.

Conclusion

People with intellectual disabilities have poorer general health than other people, especially children and young people. Accurate information on population prevalence and health status is essential to plan appropriate resources.

An evaluation of the effectiveness of annual health checks and quality of health care for adults with intellectual disability: an observational study using a primary care database

Background

People with intellectual disability (ID) have poorer health than the general population; however, there is a lack of comprehensive national data describing their health-care needs and utilisation. Annual health checks for adults with ID have been incentivised through primary care since 2009, but only half of those eligible for such a health check receive one. It is unclear what impact health checks have had on important health outcomes, such as emergency hospitalisation.

Objectives

To evaluate whether or not annual health checks for adults with ID have reduced emergency hospitalisation, and to describe health, health care and mortality for adults with ID.

Design

A retrospective matched cohort study using primary care data linked to national hospital admissions and mortality data sets.

Setting

A total of 451 English general practices contributing data to Clinical Practice Research Datalink (CPRD).

Participants

A total of 21,859 adults with ID compared with 152,846 age-, gender- and practice-matched controls without ID registered during 2009–13.

Interventions

None.

Main outcome measures

Emergency hospital admissions. Other outcomes – preventable admissions for ambulatory care sensitive conditions, and mortality.

Data sources

CPRD, Hospital Episodes Statistics and Office for National Statistics.

Results

Compared with the general population, adults with ID had higher levels of recorded comorbidity and were more likely to consult in primary care. However, they were less likely to have long doctor consultations, and had lower continuity of care. They had higher mortality rates [hazard ratio (HR) 3.6, 95% confidence interval (CI) 3.3 to 3.9], with 37.0% of deaths classified as being amenable to health-care intervention (HR 5.9, 95% CI 5.1 to 6.8). They were more likely to have emergency hospital admissions [incidence rate ratio (IRR) 2.82, 95% CI 2.66 to 2.98], with 33.7% deemed preventable compared with 17.3% in controls (IRR 5.62, 95% CI 5.14 to 6.13). Health checks for adults with ID had no effect on overall emergency admissions compared with controls (IRR 0.96, 95% CI 0.87 to 1.07), although there was a relative reduction in emergency admissions for ambulatory care-sensitive conditions (IRR 0.82, 95% CI 0.69 to 0.99). Practices with high health check participation also showed a relative fall in preventable emergency admissions for their patients with ID, compared with practices with minimal participation (IRR 0.73, 95% CI 0.57 to 0.95). There were large variations in the health check-related content that was recorded on electronic records.

Limitations

Patients with milder ID not known to health services were not identified. We could not comment on the quality of health checks.

Conclusions

Compared with the general population, adults with ID have more chronic diseases and greater primary and secondary care utilisation. With more than one-third of deaths potentially amenable to health-care interventions, improvements in access to, and quality of, health care are required. In primary care, better continuity of care and longer appointment times are important examples that we identified. Although annual health checks can also improve access, not every eligible adult with ID receives one, and health check content varies by practice. Health checks had no impact on overall emergency admissions, but they appeared influential in reducing preventable emergency admissions.

Future work

No formal cost-effectiveness analysis of annual health checks was performed, but this could be attempted in relation to our estimates of a reduction in preventable emergency admissions.

Management and prevalence of long-term conditions in primary health care for adults with intellectual disabilities compared with the general population: A population-based cohort study

BACKGROUND

In the UK, general practitioners/family physicians receive pay for performance on management of long-term conditions, according to best-practice indicators.

METHOD

Management of long-term conditions was compared between 721 adults with intellectual disabilities and the general population (n = 764,672). Prevalence of long-term conditions was determined, and associated factors were investigated via logistic regression analyses.

RESULTS

Adults with intellectual disabilities received significantly poorer management of all long-term conditions on 38/57 (66.7%) indicators. Achievement was high (75.1%-100%) for only 19.6% of adults with intellectual disabilities, compared with 76.8% of the general population. Adults with intellectual disabilities had higher rates of epilepsy, psychosis, hypothyroidism, asthma, diabetes and heart failure. There were no clear associations with neighbourhood deprivation.

CONCLUSIONS

Adults with intellectual disabilities receive poorer care, despite conditions being more prevalent. The imperative now is to find practical, implementable means of supporting the challenges that general practices face in delivering equitable care.

Screening for glucose intolerance and development of a lifestyle education programme for prevention of type 2 diabetes in a population with intellectual disabilities: the STOP Diabetes research project

Background

The prevalence of type 2 diabetes mellitus (T2DM) and of cardiovascular disease (CVD) is believed to be higher among people with intellectual disability (ID) than in the general population. However, research on prevalence and prevention in this population is limited.

Objectives

The objectives of this programme of work were to establish a programme of research that would significantly enhance the knowledge and understanding of impaired glucose regulation (IGR) and T2DM in people with ID; to test strategies for the early identification of IGR and T2DM in people with ID; and to develop a lifestyle education programme and educator training protocol to promote behaviour change in a population with ID and IGR (or at a high risk of T2DM/CVD).

Setting

Leicestershire, UK.

Participants

Adults with ID were recruited from community settings, including residential homes and family homes. Adults with mild to moderate ID who had an elevated body mass index (BMI) of ≥ 25 kg/m2and/or IGR were invited to take part in the education programme.

Main outcome measures

The primary outcome of the screening programme was the prevalence of screen-detected T2DM and IGR. The uptake, feasibility and acceptability of the intervention were assessed.

Data sources

Participants were recruited from general practices, specialist ID services and clinics, and through direct contact.

Results

A total of 930 people with ID were recruited to the screening programme: 58% were male, 80% were white and 68% were overweight or obese. The mean age of participants was 43.3 years (standard deviation 14.2 years). Bloods were obtained for 675 participants (73%). The prevalence of previously undiagnosed T2DM was 1.3% [95% confidence interval (CI) 0.5% to 2%] and of IGR was 5% (95% CI 4% to 7%). Abnormal IGR was more common in those of non-white ethnicity; those with a first-degree family history of diabetes; those with increasing weight, waist circumference, BMI, diastolic blood pressure or triglycerides; and those with lower high-density lipoprotein cholesterol. We developed a lifestyle educational programme for people with ID, informed by findings from qualitative stakeholder interviews (health-care professionals,n = 14; people with ID,n = 7) and evidence reviews. Subsequently, 11 people with ID (and carers) participated in pilot education sessions (two groups) and five people attended education for the feasibility stage (one group). We found that it was feasible to collect primary outcome measures on physical activity and sedentary behaviour using wrist-worn accelerometers. We found that the programme was relatively costly, meaning that large changes in activity or diet (or a reduction in programme costs) would be necessary for the programme to be cost-effective. We also developed a quality development process for assessing intervention fidelity.

Limitations

We were able to screen only around 30% of the population and involved only a small number in the piloting and feasibility work.

Conclusions

The results from this programme of work have significantly enhanced the existing knowledge and understanding of T2DM and IGR in people with ID. We have developed a lifestyle education programme and educator training protocol to promote behaviour change in this population.

Future work

Further work is needed to evaluate the STOP Diabetes intervention to identify cost-effective strategies for its implementation.

"Sometimes, it just stops me from doing anything": A qualitative exploration of epilepsy management in people with intellectual disabilities and their carers

PURPOSE

Epilepsy affects 1 in 5 people with an intellectual disability (ID), but little is known about their experiences of living with epilepsy. A qualitative study was conducted to investigate the impact and management of epilepsy in people with ID.

MATERIALS AND METHODS

People with epilepsy and ID and their carers were invited to take part in semi-structured interviews. Eleven participants with ID and their carers were interviewed together, one participant with ID and their carer were interviewed separately, two interviews took place with the participant with ID only, and one interview took place with the carer only. The interviews were transcribed verbatim, coded, and analyzed thematically (dual independent coding for 30% of the transcripts).

RESULTS

Three themes emerged (participant characteristics, living with epilepsy, epilepsy management and information needs) which indicated the following: 1) diversity regarding health profiles, communication abilities, severity of epilepsy, perceived control of epilepsy, and support needs; 2) a reduction in severity and frequency of seizures for a sizeable proportion of participants through antiepileptic drugs; 3) the lifelong impact of epilepsy and related seizures on participants' activities and quality of life; 4) the perceived burden of epilepsy and difficulty managing the condition for a large proportion of participants; 5) high levels of satisfaction with epilepsy-related services and care; and 6) an overall lack of written accessible information about epilepsy.

CONCLUSIONS

This study has highlighted a significant impact of epilepsy and related seizures on the daily lives and quality of life of people with ID. Although a sizeable proportion of participants and their carers considered their epilepsy to be well controlled, the majority reported difficulties managing epilepsy and minimizing its impact on their wellbeing. Excluding care staff and the support provided by epilepsy clinics, the participants had not accessed any adapted self-management or information resources about epilepsy.

Intellectual disability health content within nursing curriculum: An audit of what our future nurses are taught

BACKGROUND

Individuals with intellectual disability experience chronic and complex health issues, but face considerable barriers to healthcare. One such barrier is inadequate education of healthcare professionals.

OBJECTIVE

To establish the quantity and nature of intellectual disability content offered within Australian nursing degree curricula.

DESIGN

A two-phase national audit of nursing curriculum content was conducted using an interview and online survey.

SETTING

Australian nursing schools offering pre-registration courses.

PARTICIPANTS

Pre-registration course coordinators from 31 universities completed the Phase 1 interview on course structure. Unit coordinators and teaching staff from 15 universities in which intellectual disability content was identified completed the Phase 2 online survey.

METHODS

Quantity of compulsory and elective intellectual disability content offered (units and teaching time) and the nature of the content (broad categories, specific topics, and inclusive teaching) were audited using an online survey.

RESULTS

Over half (52%) of the schools offered no intellectual disability content. For units of study that contained some auditable intellectual disability content, the area was taught on average for 3.6h per unit of study. Units were evenly distributed across the three years of study. Just three participating schools offered 50% of all units audited. Clinical assessment skills, and ethics and legal issues were most frequently taught, while human rights issues and preventative health were poorly represented. Only one nursing school involved a person with intellectual disability in content development or delivery.

CONCLUSION

Despite significant unmet health needs of people with intellectual disability, there is considerable variability in the teaching of key intellectual disability content, with many gaps evident. Equipping nursing students with skills in this area is vital to building workforce capacity.

What Effect Does Transition Have on Health and Well-Being in Young People with Intellectual Disabilities? A Systematic Review

BACKGROUND

Transition to adulthood might be a risk period for poor health in people with intellectual disabilities. However, the present authors could find no synthesis of evidence on health and well-being outcomes during transition in this population. This review aimed to answer this question.

METHOD

PRISMA/MOOSE guidelines were followed. Search terms were defined, electronic searches of six databases were conducted, reference lists and key journals were reviewed, and grey literature was searched. Papers were selected based on clear inclusion criteria. Data were extracted from the selected papers, and their quality was systematically reviewed. The review was prospectively registered on PROSPERO: CRD42015016905.

RESULTS

A total of 15 985 articles were extracted; of these, 17 met the inclusion criteria. The results of these articles were mixed but suggested the presence of some health and well-being issues in this population during transition to adulthood, including obesity and sexual health issues.

CONCLUSION

This review reveals a gap in the literature on transition and health and points to the need for future work in this area.

Implications for public health research of models and theories of disability: a scoping study and evidence synthesis

Background

Public health interventions that are effective in the general population are often assumed to apply to people with impairments. However, the evidence to support this is limited and hence there is a need for public health research to take a more explicit account of disability and the perspectives of people with impairments.

Objectives

(1) To examine the literature on theories and models of disability; (2) to assess whether or not, and how, intervention studies of effectiveness could incorporate more inclusive approaches that are consistent with these theories and models; and (3) to use the findings to draw out implications for improving evaluative study designs and evidence-based practice.

Review methods

The project is a scoping review of the literature. The first stage examines theories and models of disability and reflects on possible connections between theories of disability and public health paradigms. This discussion is used to develop an ethical–empirical decision aid/checklist, informed by a human rights approach to disability and ecological approaches to public health. We apply this decision aid in the second stage of the review to evaluate the extent to which the 30 generic public health reviews of interventions and the 30 disability-specific public health interventions include the diverse experiences of disability. Five deliberation panels were also organised to further refine the decision aid: one with health-care professionals and four with politically and socially active disabled people.

Results

The evidence from the review indicated that there has been limited public health engagement with theories and models of disability. Outcome measures were often insensitive to the experiences of disability. Even when disabled people were included, studies rarely engaged with their experiences in any meaningful way. More inclusive research should reflect how people live and ‘flourish’ with disability.

Limitations

The scoping review provides a broad appraisal of a particular field. It generates ideas for future practice rather than a definite framework for action.

Conclusions

Our ethical–empirical decision aid offers a critical framework with which to evaluate current research practice. It also offers a resource for promoting more ethical and evidence-based public health research that is methodologically robust while being sensitive to the experiences of disability.

Future work

Developing more inclusive research and interventions that avoid conceptualising disability as either a ‘burden’ or ‘problem’ is an important starting point. This includes exploring ways of refining and validating current common outcome measures to ensure that they capture a diverse range of disabling experiences, as well as generating evidence on meaningful ways of engaging a broad range of disabled children and adults in the research process.

Do health checks for adults with intellectual disability reduce emergency hospital admissions? Evaluation of a natural experiment

BACKGROUND

Annual health checks for adults with intellectual disability (ID) have been incentivised by National Health Service (NHS) England since 2009, but it is unclear what impact they have had on important health outcomes such as emergency hospitalisation.

METHODS

An evaluation of a 'natural experiment', incorporating practice and individual-level designs, to assess the effectiveness of health checks for adults with ID in reducing emergency hospital admissions using a large English primary care database. For practices, changes in admission rates for adults with ID between 2009-2010 and 2011-2012 were compared in 126 fully participating versus 68 non-participating practices. For individuals, changes in admission rates before and after the first health check for 7487 adults with ID were compared with 46 408 age-sex-practice matched controls. Incident rate ratios (IRRs) comparing changes in admission rates are presented for: all emergency, preventable emergency (for ambulatory care sensitive conditions (ACSCs)) and elective emergency.

RESULTS

Practices with high health check participation showed no change in emergency admission rate among patients with ID over time compared with non-participating practices (IRR=0.97, 95% CI 0.78 to 1.19), but emergency admissions for ACSCs did fall (IRR=0.74, 0.58 to 0.95). Among individuals with ID, health checks had no effect on overall emergency admissions compared with controls (IRR=0.96, 0.87 to 1.07), although there was a relative reduction in emergency admissions for ACSCs (IRR=0.82, 0.69 to 0.99). Elective admissions showed no change with health checks in either analysis.

CONCLUSIONS

Annual health checks in primary care for adults with ID did not alter overall emergency admissions, but they appeared influential in reducing preventable emergency admissions.
