Health characteristics and consultation patterns of people with intellectual disability: a cross-sectional database study in English general practice

The risk of type 2-diabetes among persons with intellectual disability: a Danish population-based matched cohort study

BACKGROUND

Previous research shows that obesity, unhealthy eating, physical inactivity and a high use of psychotropic medications are prevalent among persons with intellectual disability (ID), which might increase the risk of type 2-diabetes (T2DM). This study aims to investigate: (1) whether persons with ID have an increased risk of T2DM compared with an age- and sex-matched reference group and (2) differences in T2DM risk by sex, birth year, ID inclusion diagnosis and ID severity.

METHODS

This study is a nationwide cohort study, including 65 293 persons with ID and 659 723 persons in an age- and sex-matched reference group without ID. Incidence rates for T2DM were calculated and Cox proportional regression models were used to estimate adjusted hazard ratios (aHRs) for the association between ID and T2DM. Follow-up began from the 1 January 1977 (when T2DM data were available), participants' 22nd birthday or from the date the participants immigrated to Denmark, whichever came last and continued until the onset of T2DM, emigration, death or end of follow-up (31 December 2021), whichever came first.

RESULTS

Persons with ID had more than double risk of T2DM compared with the reference group [aHR = 2.15, 95% confidence interval (CI): 2.09-2.20]. The strongest associations were found among women, persons born between 1980 and 1999 and among persons with mild ID.

CONCLUSIONS

Persons with ID have an increased risk of T2DM. This knowledge is important in relation to the development and prioritising of preventive initiatives among persons with ID in the healthcare sector. Future research should focus on the underlying mechanisms that can explain the possible association between ID and T2DM as it allows a more targeted prevention strategy.

Investigating pain-related medication use and contribution to polypharmacy in adults with intellectual disabilities: a systematic review

BACKGROUND

Adults with intellectual disability experience more pain than adults without and, despite a higher number of medications being prescribed, may be less likely to receive medication for pain. We conducted a systematic review of existing literature on medication for pain and painful conditions in adults with intellectual disability to explore if there is any association with polypharmacy, multimorbidity or demographic characteristics.

METHODS

This systematic review followed PRISMA guidelines. Medline, Embase, PubMed, PsycINFO, Web of Science, CINAHL, Cochrane Library and Scopus were searched from January 2000 to 21st October 2024. We included original, peer-reviewed observational, qualitative or mixed-method studies published in English with data on medication for pain or painful conditions in adults with intellectual disability. Two independent reviewers performed study selection, data extraction, and quality assessment; disagreements were resolved by a third reviewer. Adapted Newcastle-Ottawa Scale or the Critical Appraisal Skills Programme for qualitative studies was used for quality assessment of included studies and findings were reported via narrative synthesis. PROSPERO registration: CRD42023415051.

RESULTS

Twenty-seven of 26,170 articles met the eligibility criteria. Adults with intellectual disability were more likely to have simple analgesic medication than non-steroidal anti-inflammatory drugs, opioids or adjuvant pain medications than the general population. Psychotropic medications were more commonly prescribed in adults with intellectual disability than medication for pain or painful conditions. Adults with intellectual disability and caregivers reported under-recognition and most likely under-treatment of pain.

CONCLUSIONS

Adults with intellectual disability may receive less pharmacological management of pain with analgesics and medication for painful conditions despite the high prevalence of polypharmacy, suggesting pain is under-treated. Better assessment and pharmacological treatment of pain and painful conditions is a key future research priority to address this health inequality and improve quality of life for this vulnerable group of people.

Comparing the number and length of primary care consultations in people with and without intellectual disabilities and health needs: observational cohort study using electronic health records

BACKGROUND

In the United Kingdom, 15-min appointments with the general practitioner (GP) are recommended for people with complex health conditions, including intellectual disabilities and health needs, but we do not know whether this happens.

AIMS

We compared number and length of primary care consultations (GP, nurse, other allied health, other) for people with and without intellectual disabilities and health needs.

METHODS

Linked primary care data from the Clinical Practice Research Datalink (CPRD) in England were used to investigate face-to-face and telephone primary care consultations in 2017-2019. Health needs investigated were: epilepsy; incontinence; severe visual/hearing impairments; severe mobility difficulties; cerebral palsy; and percutaneous endoscopic gastrostomy feeding. Age and gender-standardized consultation rates per year (Poisson), duration of consultations, and the proportion of "long consultations" (≥15 min) were reported.

RESULTS

People with intellectual disabilities (n = 7,794) had 1.9 times as many GP consultations per year as those without (n = 176,807; consultation rate ratio = 1.87 [95% confidence interval 1.86-1.89]). Consultation rates with nurses and allied healthcare professionals were also twice as high. Mean GP consultation time was 9-10 min regardless of intellectual disability/health need status. Long GP consultations were less common in people with intellectual disabilities (18.2% [17.8-18.7] vs. 20.9% [20.8-21.0]). Long consultations with practice nurses were more common in people with health needs, particularly severe visual loss.

CONCLUSIONS

People with intellectual disabilities and/or health needs tend to have more, rather than longer, GP consultations compared with the rest of the population. We recommend further investigation into the role of practice nurses to support people with intellectual disabilities and health needs.

Asthma and COPD management of patients with intellectual disabilities in general practice

People with intellectual disabilities experience overall poorer health and healthcare access than the general population. It is largely unknown how this applies to asthma and chronic obstructive pulmonary disease (COPD) management by general practitioners (GPs). In a 10-year retrospective matched cohort study, n = 34,429, we examined year prevalence of asthma and COPD in adult patients with and without intellectual disabilities and potential differences in the delivery of asthma and COPD disease management activities in Dutch general practices (2010-2019). We collected information on patient characteristics, comorbidity, consultation patterns, use and outcomes of asthma/COPD control questionnaires, spirometry measurement, pulmonology referrals, and prescribed medication. Asthma patients with intellectual disabilities suffered more frequently from obesity (53.2% vs. 39.5% without intellectual disabilities), and both asthma and COPD patients with intellectual disabilities were more frequently current smokers (45.2% vs. 22.1% without intellectual disabilities, and 76.6% vs. 51.4% without intellectual disabilities, respectively). Also, a statistically significant larger number of asthma patients with intellectual disabilities were prescribed antibiotics (69.9% vs. 54.5%). COPD patients with intellectual disabilities, compared with matched controls without intellectual disabilities, received significantly more often either no COPD-related practice consultation at all (respectively 20.8% vs. 8.5%, p = 0.004) or a large number of practice consultations (>31 consultations, respectively 16.7% vs. 5.3%, p = 0.004). For asthma, there was no statistical difference between patients with or without intellectual disabilities regarding the number and type of consultations. The asthma year point prevalence in patients with intellectual disabilities was, from 2014 onward, significantly higher, and in 2019 was 8.7% vs. 6.0% for people without intellectual disabilities. For COPD, it was comparable in both groups. Both asthma and COPD patients with intellectual disabilities appeared considerably younger in age than patients without intellectual disabilities. Our findings warrant further research into the causes of the differences found for asthma and COPD and whether they also infer differences in the quality or the effectiveness of GP disease management, especially for young adults with intellectual disabilities.

Annual health checks for people with intellectual disabilities: An exploration of experiences, follow-up and self-management of health conditions

BACKGROUND

Little is known about how health issues identified at the annual health check (AHC) are followed up and addressed, how participants self-manage their health in between AHCs, and what support they receive. This research aimed to explore this.

METHODS

People with intellectual disabilities (n = 12), and/or their supporters residing in Wales, were interviewed following their AHC and again at 6 and 11 months. A recurrent cross-sectional thematic analysis was undertaken.

RESULTS

Five main themes emerged from interview one: going for a health check, issues identified, and actions taken, supporting the self-management of health, the personal context, and addressing health inequities. Four main themes emerged from follow-up interviews: follow-up, supporting the self-management of health, the need for reasonably adjusted health services, and going for another health check.

CONCLUSION

A broader system of support around the AHC is required if people are to achieve or maintain the best possible health.

Identifying barriers and facilitators to primary care practitioners implementing health assessments for people with intellectual disability: a Theoretical Domains Framework-informed scoping review

INTRODUCTION

People with intellectual disability experience poorer health outcomes compared with the general population, partly due to the difficulties of accessing preventive care in primary care settings. There is good evidence that structured annual health assessments can enhance quality of care for people with intellectual disability, and their use has become recommended policy in several high-income countries. However, uptake remains low. The Theoretical Domains Framework (TDF) offers a conceptual structure for understanding barriers to implementation and has been usefully applied to inform implementation of health assessments for other high-need groups, but not for people with intellectual disability. We conducted a scoping review of the literature, using the TDF, to identify barriers and facilitators influencing primary care practitioners' implementation of annual health assessments for people with intellectual disability as part of routine primary care practice.

METHODS

This study was conducted according to the JBI methodological approach for scoping reviews. Searches were conducted in Medline (OVID-SP), Embase (OVID-SP), PsycINFO (OVID-SP), CINHAL (EBSCO), Scopus (Elsevier) and Web of Science (Clarivate) for relevant peer-reviewed publications up to May 2023. Screening, full-text review and data extraction were completed by two independent reviewers. Data were extracted and mapped to the TDF to identify relevant barriers and facilitators.

RESULTS

The search yielded 1057 publications, with 21 meeting the inclusion criteria. Mapping data to the TDF, the most frequently identified domains were (a) environmental context and resources, (b) skills, (c) knowledge and (d) emotion. Predominant factors impacting on implementation included practitioners' lack of awareness about health assessments and their identified benefits; inadequate training and experience by practitioners in the delivery of health assessments for people with intellectual disability; insufficient time to provide health assessments; and practitioner burnout.

CONCLUSION

Using a theory-informed behavioural framework, our review aids understanding of the barriers and facilitators to improving the implementation of health assessments as part of routine care for people with intellectual disability. However, there is a clear need for further qualitative research to examine the perceptions of primary care practitioners regarding implementation barriers and facilitators to health assessments in general, including views from practitioners who are not currently undertaking health assessments.

Risk of post-fracture pneumonia and its association with cardiovascular events and mortality in adults with intellectual disabilities

Objective

Fragility fractures are associated with an increased risk of pneumonia, which is a leading cause of death in adults with intellectual disabilities; however, the timing and complications of post-fracture pneumonia are underinvestigated. The objectives of this study were to determine the 30-day pneumonia rate post-fracture and the association of post-fracture pneumonia with mortality and cardiovascular events among adults with intellectual disabilities.

Methods

This retrospective cohort study was conducted using Medicare and commercial claims from 01 January 2011 to 31 December 2016. Incidence of pneumonia 30 days after a fragility fracture among adults ≥18 years old with intellectual disabilities (Fx cohort) was compared to the incidence among matched adults with intellectual disabilities without fractures (w/oFx cohort) and the general population of patients with an incident fragility fracture (GP+Fx). For the Fx cohort, Cox regression was used to examine the adjusted association of time-varying pneumonia (within 30 days post-fracture) with mortality and incidence of cardiovascular events 0-30, 31-365, and 366-730 days post-fracture.

Results

There was a high-early rate of pneumonia within 30 days post-fracture for young, middle-aged, and elderly adults with intellectual disabilities (n = 6,183); this rate was 2.2- to 6.1-fold higher than the rate among the w/oFx (n = 12,366) and GP+Fx (n = 363,995) cohorts (all P < 0.05). For the Fx cohort, post-fracture 30-day incidence of pneumonia was associated with an increased 30-day rate of mortality (adjusted HR [aHR] = 5.19; 95% confidence interval [CI] = 3.68-7.32), heart failure (aHR = 2.96; 95% CI = 1.92-4.56), and cerebrovascular disease (aHF = 1.48; 95% CI = 0.93-2.35; P = 0.098), with sustained effects to 1 year for heart failure (aHR = 1.61; 95% CI = 1.19-2.17) and 2 years for mortality (aHR = 1.39; 95% CI = 1.06-1.83), and without evidence of effect modification by age.

Discussion

Adults with intellectual disabilities are vulnerable to post-fracture pneumonia within 30 days, and complications arising from this, across the adult lifespan, and not only during the elderly years.

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.

Chronic disease management in patients with intellectual disabilities: a matched study in Dutch general practice

BACKGROUND

Disease management programmes (DMPs) aim to deliver standardised, high- quality care to patients with chronic diseases. Although chronic diseases are common among people with intellectual disabilities (ID), this approach may be suboptimal for meeting their care needs.

AIM

To examine differences between patients with and without ID who have a chronic illness in DMP enrolment and disease monitoring in Dutch general practice.

DESIGN AND SETTING

Observational study utilising the Nivel Primary Care Database (2015-2018) comparing patients with ID and cardiovascular disease, diabetes mellitus, or chronic obstructive pulmonary disease (COPD) with matched (1:5) controls with these conditions but without ID.

METHOD

Using conditional logistic regression, enrolment in DMP per chronic disease was examined and differences tested between groups in the frequencies of consultations, medication prescriptions, and routine examinations.

RESULTS

A total of 2653 patients with chronic illness with ID were matched with 13 265 controls without ID. Patients with both diabetes mellitus and ID were more likely than controls to be enrolled in DMP (odds ratio [OR] = 1.44, 95% confidence interval [CI] = 1.27 to 1.64). Independent of DMP enrolment, patients with chronic illness with ID were more likely than controls to have frequent consultations. Patients with both diabetes mellitus and ID and patients with both COPD and ID who were not enrolled in DMPs had more medication prescriptions than non-enrolled patients with diabetes or COPD but without ID (OR = 1.46, 95% CI = 1.10 to 1.95; OR = 1.28, 95% CI = 0.99 to 1.66, respectively). Most patients with ID and their controls enrolled in DMPs received routine examinations at similar frequencies.

CONCLUSION

Although DMPs do not specifically address the needs of patients with both chronic illness and ID, these patients do not seem underserved in the management of chronic diseases in terms of consultation, medication, and tests.

Predictors of specialist somatic healthcare utilization among older people with intellectual disability and their age-peers in the general population: a national register study

OBJECTIVES

To compare somatic healthcare usage among older people with intellectual disabilities (ID) to that of their age-peers in the general population, taking into account health and demographic factors, and to identify predictors for somatic healthcare usage among older people with ID.

PARTICIPANTS

Equally sized cohorts, one with people with ID and one referent cohort, one-to-one-matched by sex and year of birth, were created. Each cohort comprised 7936 people aged 55+ years at the end of 2012.

DESIGN

Retrospective register-based study.

SETTING

All specialist inpatient and outpatient healthcare clinics in Sweden.

OUTCOME MEASURES

Data regarding planned/unplanned and inpatient/outpatient specialist healthcare were collected from the Swedish National Patient Register for 2002-2012. Diagnoses, previous healthcare usage, sex, age and cohort affiliation was used to investigate potential impact on healthcare usage.

RESULTS

Compared with the referent cohort, the ID cohort were more likely to have unplanned inpatient and outpatient care but less likely to have planned outpatient care. Within the ID cohort, sex, age and previous use of healthcare predicted healthcare usage.

CONCLUSIONS

Older people with ID seem to have lower risks of planned outpatient care compared with the general population that could not be explained by diagnoses. Potential explanations are that people with ID suffer from communication difficulties and experience the healthcare environment as unfriendly. Moreover, healthcare staff lack knowledge about the particular needs of people with ID. Altogether, this may lead to people with ID being exposed to discrimination. Although these problems are known, few interventions have been evaluated, especially related to planned outpatient care.

High cardiorespiratory disease burden following a fracture among adults with intellectual disabilities

BACKGROUND

Adults with intellectual disabilities have a greater risk for fragility fractures that begin to accumulate early in the adult lifespan, which may contribute to accelerated health declines. The objective was to determine if fragility fractures were associated with an increased 2-year rate of cardiorespiratory diseases among adults with intellectual disabilities.

METHOD

This retrospective cohort study used nationwide administrative claims data from 01/01/2011-12/31/2016 from the Medicare fee-for-service database. 2-year incidence of cardiorespiratory diseases were compared between adults ≥18 years old with intellectual disabilities with (n = 6183) vs. without (n = 67,842) an incident fragility fracture after confounder adjustment using Cox regression.

RESULTS

Fracture at the vertebral column, hip, non-proximal femur, tibia/fibula, and multiple sites had an elevated hazard ratio (HR) compared to those with no fracture for pneumonia, respiratory failure, heart failure, and cerebrovascular disease (HR range, 1.15-2.09, all P < 0.05), while humerus and radius/ulna fracture were associated with an elevated HR for congestive heart failure and cerebrovascular disease (HR range, 1.38-1.72, all P < 0.05).

CONCLUSIONS

Fragility fractures were associated with an increased incidence of cardiorespiratory diseases among adults with intellectual disabilities.

Association of intellectual disability with overall and type-specific cardiovascular diseases: a population-based cohort study in Denmark

BACKGROUND

Individuals with mental health problems have been shown to have an increased risk of cardiovascular disorder (CVD), but little is known about the risk of early-onset CVD among those with intellectual disability. We aimed to investigate the association between intellectual disability and subsequent CVD, taking into consideration the severity of intellectual disability and neurodevelopmental and neurologic comorbidity.

METHODS

This population-based cohort study used individual-level linked data from Danish national health registries. Participants were all live-born singletons born in Denmark during 1978-2016 (n = 2,288,393). Follow-up began from birth and continued until the onset of CVD, death, emigration, or December 31, 2018, whichever came first. Clinical diagnosis of any CVD or type-specific CVDs was identified in the Danish National Patient Register. Time-varying Cox regression analyses were used to estimate the hazard ratio (HR) of intellectual disability associated with overall and type-specific CVDs.

RESULTS

A total of 11,954 individuals received a diagnosis of intellectual disability (7434 males and 4520 females). During a median follow-up time of 18.5 years (interquartile range, 18.1 years), 652 individuals with intellectual disability (5.5%) received a diagnosis of CVD (incidence rate, 2.4 per 1000 person-years), compared with 78,088 (3.4%) CVD cases in individuals without intellectual disability (incidence rate, 1.9 per 1000 person-years), corresponding to a HR of 1.24 (95% CI, 1.15-1.34). Increased risks of CVD were similar in both childhood (HR, 1.24; 95% CI, 1.08-1.43) and early adulthood (HR, 1.25; 95% CI, 1.14-1.38). For type-specific CVDs, intellectual disability was significantly associated with cerebrovascular disease (HR, 2.50; 95% CI, 2.02-3.10), stroke (HR, 2.20; 95% CI, 1.69-2.86), heart failure (HR, 3.56; 95% CI, 2.37-5.35), hypertensive disease (HR, 1.30; 95% CI, 1.22-1.39), and deep vein thrombosis (HR, 2.10; 95% CI, 1.60-2.75). Stratified HRs of overall CVD were 1.14 (95% CI, 1.01-1.30) for borderline/mild intellectual disability, 1.25 (95% CI, 1.01-1.54) for moderate intellectual disability, and 1.91 (95% CI, 1.47-2.48) for severe/profound intellectual disability. After the exclusion of individuals with neurodevelopmental and neurologic comorbidity, intellectual disability remained significantly associated with increased risks of CVD.

CONCLUSIONS

Individuals with intellectual disability had increased risks of early-onset CVD, in particular, for cerebrovascular disease, stroke, heart failure, and deep vein thrombosis, and the risks also increased with the severity of intellectual disability. Our findings highlight the awareness of increased risks of CVD in intellectual disability patients.

Use of psychotropic medications in adults with intellectual disability: A systematic review and meta-analysis

OBJECTIVE

This study presents the proportion of adults with intellectual disability using psychotropic medications including antipsychotics, antidepressants, anxiolytics, hypnotics and sedatives, and psychostimulants.

METHODS

A search was performed in PubMed, Embase, PsycINFO, Web of Science, and Scopus up to 31 December 2021. Articles were included if they reported the proportion of adults with intellectual disability using psychotropic medications. Frequency of use was estimated using a random effects meta-analysis. Meta-regression analysis was used to assess the association between study-level characteristics and variability in estimates, when heterogeneity was considerable.

RESULTS

Twenty-four articles were included in pooled analysis. The pooled prevalence of psychotropic medications was 41% (95% confidence interval: 35-46%). Pooled prevalences of subclasses were as follows: antipsychotics 31% (27-35%), antidepressants 14% (9-19%), anxiolytics 9% (4-15%), hypnotics/sedatives 5% (2-8%), and psychostimulants 1% (1-2%). Heterogeneity was considerable between studies, except for psychostimulants. There was no significant association between assessed characteristics and variability in prevalence estimates.

CONCLUSION

Two-fifths of adults with intellectual disability were prescribed psychotropic medications. Antipsychotics and antidepressants were used by one-third and one-seventh of adults, respectively. There was considerable variability between studies, and further investigation is required to determine the source of variability. More studies are needed to better characterise prescribed psychotropic medications, including effectiveness and adverse effects, to ensure appropriate use of these drugs.

Improving access to primary care and annual health checks for people who have a learning disability: a multistakeholder qualitative study

OBJECTIVES

To investigate key stakeholders' views on how to improve access to primary care in general practice settings for people with learning disabilities (or intellectual disabilities). Further to explore how inequalities and barriers in specific areas including annual health checks might be addressed.

DESIGN

A qualitative study design was used with data collected during focus groups, interviews and open-response surveys; data analysis was thematic and informed by stakeholder consultation. Processes to facilitate quality included triangulation of stakeholder perspectives, triangulation of data collection methods and checking interpretation of findings with participants.

SETTING

UK regional services including learning disability organisations, primary care general practitioner (GP) clinical practice networks and supported housing organisations.

PARTICIPANTS

Sixteen people participated in the study: four people with learning disabilities participated in a focus group; four relatives completed an interview or survey; eight GPs, practice nurses and supported housing managers participated in interviews.

RESULTS

Five overarching themes describing approaches to improve primary care access for people with learning disabilities were identified including: prioritisation, proactivity, innovation and improvement, personalisation and prevention and follow-up. Definitions of themes were described and illustrated with quotes. Ten recommendations informed by the thematic analysis, stakeholder consultation, research and primary care guidance were codeveloped with people with learning disabilities.

CONCLUSIONS

All stakeholders identified problems, with primary care interfaces being misaligned with the needs of people with learning disabilities. The recommendations informed by all stakeholders can be used to guide development of service provision to better meet the needs of people with learning disabilities in primary care. Future research should explore professionals' understanding of reasonable adjustments.

Primary mental healthcare for adults with mild intellectual disabilities: a Dutch database study

BACKGROUND

General practitioners (GPs) are increasingly confronted with people with both mild intellectual disability (MID) and mental health (MH) problems. Little is known about the type of MH problems for which people with MID visit their GP and the care provided.

OBJECTIVES

To identify the type and prevalence of MH disorders and MH-related complaints in people with MID in primary care and care provided, compared to people without ID.

METHODS

By linking the Netherlands Institute for Health Services Research's primary care databases, comprising electronic health records, with Statistic Netherlands' social services and chronic care databases, we identified 11,887 people with MID. In this four-year retrospective study, MH-related International Classification of Primary Care (ICPC) codes and care characteristics were compared between people with MID and without ID.

RESULTS

Of the people with MID, 48.8% had MH problems recorded vs. 30.4% of the people without ID, with significant differences in substance abuse, suicide attempts, and psychosis. Of the MID group, 80.3% were not registered by their GP with the ICPC code mental retardation. GPs provided more care to people with MID and MH problems than people without ID but with MH-problems regarding consultations (median 6.4 vs. 4.0 per year) and variety of prescribed medications (median 2.7 vs. 2.0 per year).

CONCLUSION

In primary care, the prevalence of MH problems and care provided is high in people with MID. To improve primary mental healthcare for this group, it is essential to increase GPs' awareness and knowledge on the combination of MID and MH.

Access to general practice for people with intellectual disability in Australia: a systematic scoping review

BACKGROUND

People with intellectual disability experience inadequate access to general practice and poorer health outcomes than the general population. While some access barriers have been identified for this population, these studies have often used narrow definitions of access, which may not encompass the multiple dimensions that influence access to general practice. To address this gap, we conducted a scoping review to identify factors impacting access to general practice for people with intellectual disability in Australia, using a holistic framework of access conceptualised by Levesque and colleagues.

METHODS

This scoping review followed Joanna Briggs Institute methodology and was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. Medline (Ovid), Scopus, CINAHL, Informit and PsycINFO databases were searched. Screening, full-text review and data extraction were completed by two independent reviewers, with consensus reached at each stage of the study. Data were extracted, coded and synthesised through deductive qualitative analysis - using the five corresponding conceptual dimensions within Levesque and colleagues' theoretical framework of access, which incorporate both supply-side features of health systems and services, and demand-side characteristics of consumers and populations.

RESULTS

The search identified 1364 publications. After duplicate removal, title and abstract screening and full-text review, 44 publications were included. Supply-side factors were more commonly reported than demand-side factors, with the following issues frequently identified as impacting access to general practice: limited general practitioner education about, and/or experience of, people with intellectual disability; communication difficulties; and inadequate continuity of care. Less frequently included were factors such as the health literacy levels, promotion of general practice services and availability of complete medical records.

CONCLUSIONS

This is the first scoping review to assess access barriers for people with intellectual disability using a comprehensive conceptualisation of access. The findings highlight the need for increased efforts to address demand-side dimensions of access to general practice and offer a basis for a balanced portfolio of strategies that can support recent policy initiatives to enhance access to care for people with intellectual disability.

Opening the door to university health research: recommendations for increasing accessibility for individuals with intellectual disability

BACKGROUND

Advances in health equity rely on representation of diverse groups in population health research samples. Despite progress in the diversification of research samples, continued expansion to include systematically excluded groups is needed to address health inequities. One such group that is infrequently represented in population health research are adults with intellectual disability. Individuals with intellectual disability experience pervasive health disparities. Representation in population health research is crucial to determine the root causes of inequity, understand the health of diverse populations, and address health disparities. The purpose of this paper was to develop recommendations for researchers to increase the accessibility of university health research and to support the inclusion of adults with intellectual disability as participants in health research.

METHODS

A comprehensive literature review, consultation with the university ethics review board, and review of United States federal regulations was completed to identify barriers to research participation for individuals with intellectual disability. A collaborative stakeholder working group developed recommendations and products to increase the accessibility of university research for participants with intellectual disability.

RESULTS

Eleven key barriers to research participation were identified including gaps in researchers' knowledge, lack of trust, accessibility and communication challenges, and systematic exclusion among others. Together the stakeholder working group compiled seven general recommendations for university health researchers to guide inclusion efforts. Recommendations included: 1) address the knowledge gap, 2) build community partnerships, 3) use plain language, 4) simplify consent and assent processes, 5) establish research capacity to consent, 6) offer universal supports and accommodations, and 7) practice accessible dissemination. In addition, four products were created as part of the stakeholder working group to be shared with researchers to support the inclusion of participants with intellectual disability. 1) Supports I Need Checklist, 2) Plain language glossary of health and research terms, 3) Understanding Consent and Assent in Plain Language, 4) Easy-Read Paper Template.

CONCLUSION

Community members and individuals with intellectual disability want to be included in research and are eager to engage as research participants. It is the responsibility of the researcher to open the door to university health research. The recommendations discussed in this paper could increase accessibility for a broader range of research participants and, in particular, promote the inclusion of individuals with intellectual disability to advance health equity in population health research.

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

Background

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

Methods and findings

Using linked administrative datasets, we conducted a retrospective cohort study of people aged 5–64 years with an acute hospitalisation for epilepsy from 2005–2014 in New South Wales, Australia. Acute readmission and ED presentation rates within 30, 90, and 365 days of the index hospitalisation were estimated and compared between people with and without intellectual disability using modified Poisson regression. Of 13537 individuals with an index hospitalisation, 712 children and 1862 adults had intellectual disability. Readmission and ED presentation after the index hospitalisation were common in people with intellectual disability. Within 30 days, 11% of children and 15.6% of adults had an all-cause readmission and 18% of children and 23.5% of adults had an ED presentation. Over 60% of both children and adults presented to an ED within a year. Neurological, respiratory, and infectious conditions were overrepresented reasons for readmission in people with intellectual disability. Age-adjusted relative risks (RRs) within each period showed a higher risk of readmission and ED presentation in children and adults with intellectual disability than without. Most RRs remained statistically significant after controlling for covariates. The largest adjusted RRs were observed for readmission for epilepsy (RR 1.70, 95% CI: 1.42 to 2.04) and non-epilepsy related conditions (RR 1.73, 95%: CI 1.43 to 2.10) in children. Study limitations include lack of clinical data.

Conclusions

Increased risk of returning to acute care after epilepsy hospitalisation suggests there is a need to improve epilepsy care for people with intellectual disability. We recommend research into strategies to improve management of both seizures and comorbidity.

Health Needs and Their Relationship with Life Expectancy in People with and without Intellectual Disabilities in England

Health needs are common in people living with intellectual disabilities, but we do not know how they contribute to life expectancy. We used the Clinical Practice Research Datalink (CPRD) linked with hospital/mortality data in England (2017-2019) to explore life expectancy among people with or without intellectual disabilities, indicated by the presence or absence, respectively, of: epilepsy; incontinence; severe visual loss; severe visual impairment; severe mobility difficulties; cerebral palsy and PEG feeding. Life expectancy and 95% confidence intervals were compared using flexible parametric methods. At baseline, 46.4% (total n = 7794) of individuals with intellectual disabilities compared with 9.7% (total n = 176,807) in the comparison group had ≥1 health need. Epilepsy was the most common health need (18.7% vs. 1.1%). All health needs except hearing impairment were associated with shorter life expectancy: PEG feeding and mobility difficulties were associated with the greatest loss in life years (65-68% and 41-44%, respectively). Differential life expectancy attenuated but remained (≈12% life years lost) even after restricting the population to those without health needs (additional years expected to live at 10 years: 65.5 [60.3, 71.1] vs. 74.3 [73.8, 74.7]). We conclude that health needs play a significant role but do not explain all of the differential life expectancy experienced by people with intellectual disabilities.

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

Adults with intellectual disability have high health care needs. Despite frequent contact with health services, they often receive inadequate health care. One method to improve health care delivery is reasonable adjustments, that is, the adaptation of health care delivery such that barriers to participation are removed for the person with disability. A starting point for the provision of reasonable adjustments is recognition of intellectual disability during the health care contact. To determine rates and predictors of the recognition of intellectual disability during hospital admissions, and its impact on admission metrics, we examined a population of adults with intellectual disability identified from disability services datasets from New South Wales, Australia between 2005 and 2014. Recognition of intellectual disability was determined by the recording of an International Classification of Diseases 10^th revision (ICD-10) diagnostic code for intellectual disability during a given hospital admission. We examined how recognition of intellectual disability related to length of hospital episodes. We found an overall low rate of recognition of intellectual disability (23.79%) across all hospital episodes, with the proportion of hospital episodes recognising intellectual disability decreasing from 2005–2015. Admissions for adults with complex health profiles (e.g., those with many comorbidities, those with Autism Spectrum Disorder, and those admitted for urgent treatment) were more likely to recognise intellectual disability, but admissions for adults with complexity in other domains (i.e., for those in custody, or those with drug and alcohol disorders) were less likely to recognise intellectual disability. Recognition of intellectual disability was associated with longer episodes of care, possibly indicating the greater provision of reasonable adjustments. To improve the recognition of intellectual disability for adults during health service contacts, we advocate for the implementation of targeted initiatives (such as a nationwide disability flag to be included in health service records) to improve the provision of reasonable adjustments.

Adults with intellectual disabilities and mental health disorders in primary care: a scoping review

BACKGROUND

GPs are increasingly confronted with patients with both intellectual disabilities (ID) and mental health disorders (MHD). Currently, the care provided to these patients is found to be insufficient, putting them at risk of developing more severe MHD. Improving the quality of GP care will improve the whole of mental health care for this patient group. Therefore, an overview of the content and quality of care provided to them by the GP may be helpful.

AIM

To provide an up-to-date literature overview of the care provided by GPs to patients with ID and MHD, identify knowledge gaps, and inform research, practice, and policy about opportunities to improve care.

DESIGN AND SETTING

Scoping review.

METHOD

PubMed, PsycINFO, EMBASE, and grey literature were searched for publications concerning primary care and patients with ID and MHD. Selected publications were analysed qualitatively.

RESULTS

One hundred publications met the inclusion criteria. Five overarching themes were identified: GP roles, knowledge and experience, caregiver roles, collaboration, and a standardised approach. The results show GPs' vital, diverse, and demanding roles in caring for patients with both ID and MHD. GPs experience problems in fulfilling their roles, and gaps are identified regarding effective GP training programmes, applicable guidelines and tools, optimal collaborative mental health care, and corresponding payment models.

CONCLUSION

The improvement required in the current quality of GP care to patients with ID and MHD can be achieved by bridging the identified gaps and initiating close collaborations between care professionals, policymakers, and organisational managers.

Statin prescription and CV risk assessment in adult psychiatric outpatients with intellectual disability

We performed a single-centre study to assess the risk of cardiovascular disease (CVD) in psychiatry outpatients with intellectual disability (ID) using the QRISK-3 score. There were 143 patients known to the ID psychiatry clinic enrolled. Of these, 28 (19.6%) had elevated CVD risk - defined as 10-year risk of heart attack or stroke of ≥10%. Of these, 57.1% were not prescribed statin therapy, which - after lifestyle measures - is recommended by National Institute for Health and Care Excellence (NICE) guidelines. The mean QRISK-3 score was 6.31% (95% confidence interval [CI] 4.84 to 7.78), with a relative risk of 3.50 (95%CI 2.34 to 4.67) compared with matched controls. The high CVD risk identified in this study supports routine CVD risk assessment and management in adult outpatients with ID. Appropriate lifestyle measures and statin therapy could help reduce the excess CVD-related morbidity and mortality in ID patients.

Exploring chronic disease prevalence in people with intellectual disabilities in primary care settings: A scoping review

BACKGROUND

Primary care providers require accurate evidence on chronic disease prevalence in people with intellectual disabilities in order to apply this information into practice. This study aimed to map the broadness of literature on chronic disease prevalence in people with and without intellectual disabilities, and to explore main characteristics of these studies.

METHOD

A scoping review of peer-reviewed literature was conducted, covering 2000 to February 2020, including literature that discussed chronic disease prevalence in people with and without intellectual disabilities, with similar data collection method for both groups.

RESULTS

Nineteen studies were included. Chronic disease prevalence varied considerably between people with and without intellectual disabilities. Studies differed in their methodologies, country and age groups that were enrolled.

CONCLUSIONS

Primary care providers should interpret results on disease prevalence among people with intellectual disabilities in light of the study characteristics. Researchers should always interpret prevalence rates in the context of methodology.

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.

Healthcare utilisation patterns among older people with intellectual disability and with affective and anxiety diagnoses in comparison with the general population

OBJECTIVES

This study investigates specialist healthcare visits of older people with intellectual disability ID having affective and anxiety diagnoses in comparison with the general population, as well as across different levels of ID, behavioural impairment, and living in special housing in Sweden.

METHOD

The study is a retrospective national-register-based study from 2002-2012 of people with ID 55 years and older (n = 7936) and a control group the same size matched by birth year and sex from the general population at the end of study. The study groups comprised those with affective (n = 918) and anxiety (n = 825) diagnoses who visited specialist healthcare, including data about living in special housing at the end of study in 2012.

RESULTS

Older people with ID and with affective and anxiety diagnoses have a higher risk of inpatient and unplanned visits to psychiatric and somatic healthcare than the general population. The average length of stay in inpatient psychiatric healthcare was higher in older people with ID and anxiety diagnoses than in the general population. Within the ID group, more inpatient and unplanned visits were made by those with moderate and severe levels of ID, behavioural impairment, and living in special housing.

CONCLUSION

Older people with ID and affective and anxiety diagnoses are more likely to have inpatient and unplanned visits for specialist healthcare than the general population. Future research should explore the quality of healthcare services delivered by healthcare providers to older people with ID and with affective and anxiety diagnoses.

Patient involvement to explore research prioritisation and self-care management in people with periodontitis and diabetes

Aim To investigate, firstly, research priorities for people with periodontitis and those with periodontitis and diabetes. Secondary aims were to explore disease self-management barriers, difficulties and enhancers for people with periodontitis and/or diabetes, mutual learning in patient groups regarding self-care and views of academic researchers on patient-derived research prioritisation.Materials and methods Research prioritisation and self-care management was based on the James Lind Alliance workshop methodology. Participants generated and ranked research priorities and enhancers and barriers to self-care management. Semi-structured interviews were undertaken to explore the views of academic staff about patient and public involvement (PPI) and the findings from this research.Results Periodontitis patients ranked preventive educational interventions highest, whereas the top priority for those with both periodontitis and diabetes was increasing public awareness about periodontitis and systemic health links. Regarding self-care, both periodontitis and diabetes groups highly ranked the importance of being able to self-assess their condition and efficacy of management. Important barriers for the diabetes patients were psychological issues, while for periodontitis patients, the main barrier was receiving conflicting or lacking information. Both groups reported that shared learning helped to develop a better understanding of their conditions and improved management. Academics believed it was essential to involve patients in developing research and most felt the findings would influence their institutions' research priorities; however, they would not change their own research only based on patients' perspectives.Conclusions The workshops led to new insights for research priorities and approaches for health self-management. PPI should be further investigated across oral health applications.

Reasonable adjustments for people with intellectual disability in acute care: a scoping review of the evidence

OBJECTIVES

People with intellectual disability are vulnerable in terms of health service provision due to increased comorbidity, higher dependency and cognitive impairment. This review explored the literature to ascertain what reasonable adjustments are evident in acute care to support people with intellectual disability, ensuring they have fair access and utilisation of health services.

DESIGN

Scoping review.

SETTING

Acute care settings.

METHODS

Five databases were systematically searched to identify studies that reported on the implementation of reasonable adjustments. Authors worked in pairs to screen studies for inclusion, data were extracted and charted and findings were synthesised according to content and themes.

RESULTS

Of the 7770 records identified, six studies were included in the review. The volume of evidence was influenced by specific inclusion criteria, and only papers that reported on the actual implementation of a reasonable adjustment within an acute care setting were included. Many papers reported on the concept of reasonable adjustment; however, few identified its applications in practice.

CONCLUSIONS

The scoping review highlights a lack of research on the practice and implementation of reasonable adjustments within acute care settings. There is a need for increased support, education and the provision of intellectual disability specialists across acute care settings.

An exploration of lifestyle/obesity programmes for adults with intellectual disabilities through a realist lens: Impact of a 'context, mechanism and outcome' evaluation

BACKGROUND

Obesity is higher in people with intellectual disabilities.

AIMS

There are two aims of this explorative paper. Firstly, using a realist lens, to go beyond 'what works' and examine the 'context, mechanisms and outcomes' (CMO) of lifestyle/obesity programmes for this population. Second, using a logic model framework to inform how these programmes could be implemented within practice.

METHOD

We explored six-review papers and the individual lifestyle/obesity programmes that these papers reviewed using the CMO framework.

RESULTS

There were few theoretically underpinned, multi-component programmes that were effective in the short to long-term and many failed to explore the 'context and mechanisms'. We developed a logic model and engaged in two co-production workshops to refine this model.

DISCUSSION

Using a realist approach, programmes need to be underpinned by both individual and systems change theories, be multi-component, have a closer understanding of the interplay of the 'context and mechanisms', and co-designed using a logic model framework.

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

BACKGROUND

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

RESULTS

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

CONCLUSIONS

Receipt of DS was associated with greater CMH but not psychiatric hospital utilization in people with intellectual disability and co-existing mental illness.

Epilepsy, anti-seizure medication, intellectual disability and challenging behaviour - Everyone's business, no one's priority

PURPOSE

People with Intellectual Disability (ID) and epilepsy are more likely to experience psychiatric conditions, challenging behaviour (CB), treatment resistance and adverse effects of anti-seizure medications (ASM) than those without. This population receives care from various professionals, depending on local care pathways. This study evaluates the training status, confidence, reported assessment and management practices of different professional groups involved in caring for people with ID, epilepsy and CB.

METHODS

A cross sectional survey using a questionnaire developed by expert consensus which measured self-reported training status, confidence, and approaches to assessment and management of CB in people with ID and epilepsy was distributed to practitioners involved in epilepsy and/or ID.

RESULTS

Of the 83 respondents, the majority had either a psychiatry/ID (n = 39), or Neurology/epileptology background (n = 31). Psychiatry/ID and Neurology/epileptology had similar confidence in assessing CB in ID-epilepsy cases, but Psychiatry/ID exhibited higher self-rated confidence in the management of these cases. While assessing and managing CB, Psychiatry/ID appeared more likely to consider mental health aspects, while Neurology/epileptology typically focused on ASM.

CONCLUSION

Psychiatry/ID and Neurology/epileptology professionals had varying training levels in epilepsy, ID and CB, had differing confidence levels in managing this patient population, and considered different factors when approaching assessment and management. As such, training opportunities in ID should be offered to neurology professionals, and vice versa. Based on the findings, a best practice checklist is presented, which aims to provide clinicians with a structured framework to consider causal explanations for CB in this population.

Improvements in biometric health measures among individuals with intellectual disabilities: A controlled evaluation of the Fit 5 program

BACKGROUND

Individuals with intellectual disabilities (ID) have poorer health statuses compared to the general population. Actions are needed to address health disparities and promote healthy lifestyles among individuals with ID. Moreover, studies that consider program settings for this population are needed.

OBJECTIVE

The Special Olympics health program, Fit 5, was evaluated to assess effectiveness in improving health measures for individuals with ID. The settings of programs' implementation were also considered.

METHODS

Four Special Olympics basketball teams participated as an intervention group, and three teams as a control group, in a study of the Fit 5 program that was implemented during, and as part of, a regular 8-week basketball season. Resting heart rate (RHR) and blood pressure, and height and weight to calculate Body Mass Index (BMI), were measured before and after the program. Differences in pre- and post-measures were compared between the two groups with paired samples t-tests and ANCOVA.

RESULTS

Participants in the intervention group had significantly greater improvements in resting systolic and diastolic blood pressures (p = 0.02 and 0.03, respectively) and RHR (p = 0.003). BMI increased for both groups; however, the increase in the intervention group was significantly less (p = 0.006). The Special Olympics setting was considered familiar and supportive and effectively reached individuals with ID.

CONCLUSION

The Fit 5 program positively impacts RHR and blood pressure, and could help reduce extents of BMI increases, in individuals with ID when implemented in a common setting. Further investigation of the impact of Fit 5 and similar programs in additional settings is warranted.

The impact of multicomponent programmes on balance and fall reduction in adults with intellectual disabilities: a randomised trial

BACKGROUND

One challenge a modern society faces is this: providing those vulnerable and ageing groups of adults who have intellectual disabilities with appropriate support for improving static and dynamic balance. Balance is a crucial component of physical fitness and, consequently, of fall reduction and prevention. The aim of the present randomised controlled trial was to evaluate the efficacy, after 16 weeks, that three different Special Olympics physical activity programmes had on balance and on fall reduction in adults with intellectual disabilities.

METHOD

A convenience sample of 150 persons with mild and moderate intellectual disabilities was recruited from the accessible Special Olympics Slovenia population of physically inactive adults with intellectual disabilities. The sample was randomised to the experimental group 1 (multicomponent balance-specific exercise programme group with additional workshops on such social gerontology topics as active and healthy ageing; N = 50), the experimental group 2 (multicomponent wellness programme group; N = 50) and a control group (regular Special Olympics athletic training; N = 50).

RESULTS

Significant differences were found between groups in the balance scores throughout the study period and in the ability to decrease fall frequency.

CONCLUSIONS

Balance assessment is a high predictor of frequency of falls, and among adults with intellectual disabilities, it significantly correlates with exercise. The results indicate that a multicomponent balance-specific exercise programme with a significant sociogerontological component on active ageing could be a useful intervention for intellectually disabled adults who have poor balance and who experience frequent falls.

Chronic Health Conditions in Aging Individuals with Intellectual Disabilities

Life expectancy of people with intellectual disability (ID) has increased in recent decades. However, there is little evidence of whether these extra years of life are spent in good health. The aim of this study, conducted in Spain, is to obtain information about the prevalence of chronic health conditions in people with ID over the age of 44 and compare it with that of their peers without disability. Twenty health conditions were analyzed in 1040 people with ID and 12,172 people without ID through a study of their prevalence. The findings show that chronic constipation, urinary incontinence, thyroid disorders and obesity are the most prevalent chronic diseases among individuals with ID. In addition, this population group suffers these health conditions more frequently than older adults without ID. Detection and early intervention in these health conditions will improve adequate access to social health services and subsequent treatment of aging adults with ID.

Incidence Rate of Advanced Chronic Kidney Disease Among Privately Insured Adults with Neurodevelopmental Disabilities

Purpose

Due to complex medical profiles, adults with neurodevelopmental disabilities (NDDs) may have a heightened risk for early development of chronic kidney disease (CKD) and accelerated CKD progression to advanced stages and kidney failure. The purpose of this study was to estimate the incidence rate of advanced CKD for adults with NDDs and compare the incidence rate to adults without NDDs.

Patients and Methods

Data were used from the Optum Clinformatics^® Data Mart to conduct this retrospective cohort study. The calendar year 2013 was used to identify eligible participants: individuals ≥18 years of age and without advanced CKD. Participants were followed from 01/01/2014 to advanced CKD, loss to follow-up, death, or end of the study period (12/31/2017), whichever came first. Diagnostic, procedure, and diagnosis-related group codes identified NDDs (intellectual disabilities, cerebral palsy, autism spectrum disorders), incident cases of advanced CKD (CKD stages 4+), diabetes, cardiovascular diseases, and hypertension present in the year 2013. Crude incidence rates (IR) of advanced CKD and IR ratios (IRR), comparing adults with vs without NDDs (with 95% CI) were estimated. Then, Cox regression estimated the hazard ratio (HR and 95% CI) for advanced CKD, comparing adults with NDDs to adults without NDDs while adjusting for covariates.

Results

Adults with NDDs (n=33,561) had greater crude IR of advanced CKD (IRR=1.32; 95% CI=1.24–1.42) compared to adults without NDDs (n=6.5M). The elevated rate of advanced CKD among adults with NDDs increased after adjusting for demographics (HR=2.19; 95% CI=2.04–2.34) and remained elevated with further adjustment for hypertension and diabetes (HR=2.01; 95% CI=1.87–2.15) plus cardiovascular disease (HR=1.84; 95% CI=1.72–1.97). Stratified analyses showed that the risk of advanced CKD was greater for all NDD subgroups.

Conclusion

Study findings suggest that adults with NDDs have a greater risk of advanced CKD than do adults without NDDs, and that difference is not explained by covariates used in our analysis.

Specialist psychiatric health care utilization among older people with intellectual disability - predictors and comparisons with the general population: a national register study

BACKGROUND

People with intellectual disability (ID) face considerable barriers to accessing psychiatric health care, thus there is a risk for health disparity. The aims of the present study were 1) to compare specialist psychiatric health care utilization among older people with ID to that with their age peers in the general population, taking into account demographic factors and co-morbidities associated with specialist psychiatric health care utilization and 2) to determine a model for prediction of specialist psychiatric health care utilization among older people with ID.

MATERIAL AND METHODS

We identified a national cohort of people with ID (ID cohort), aged 55+ years and alive at the end of 2012 (n = 7936), and a referent cohort from the general population (gPop cohort) one-to-one matched by year of birth and sex. Data on utilization of inpatient and outpatient specialist psychiatric health care, as well as on co-morbidities identified in either psychiatric or somatic specialist health care, were collected from the National Patient Register for the time period 2002-2012.

RESULTS

After adjusting for sex, age, specialist psychiatric health care utilization the previous year, and co-morbidities, people in the ID cohort still had an increased risk of visits to unplanned inpatient (relative risk [RR] 1.95), unplanned outpatient (RR 1.59), planned inpatient (RR 2.02), and planned outpatient (RR 1.93) specialist psychiatric health care compared with the general population. Within the ID cohort, increasing age was a predictor for less health care, whereas psychiatric health care the previous year predicted increased risk of health care utilization the current year. As expected, mental and behavioral disorders predicted increased risk for psychiatric health care. Furthermore, episodic and paroxysmal disorders increased the risk of planned psychiatric health care.

CONCLUSIONS

Older people with ID have a high need for psychiatric specialist health care due to a complex pattern of diagnoses. Further research needs to investigate the conditions that can explain the lesser psychiatric care in higher age groups. There is also a need of research on health care utilization among people with ID in the primary health care context. This knowledge is critical for policymakers' plans of resources to meet the needs of these people.

Access to primary and community health-care services for people 16 years and over with intellectual disabilities: a mapping and targeted systematic review

Background

In 2015, approximately 2.16% of adults were recorded as having intellectual disabilities. UK government policy is that adults with intellectual disabilities should access mainstream health services. However, people with intellectual disabilities experience challenges when accessing primary and community health services that can lead to inequalities and shorter life expectancy.

Objectives

To map and review the evidence on access to primary and community health-care services for adults with intellectual disabilities and their carers. To identify influencing factors for gaining access to primary and community health-care services. To determine which actions, interventions or models of service provision improve entry access to these services for people with intellectual disabilities and their carers. Finally, to identify the gaps in evidence and provide implications for health care and recommendations for research.

Data sources

MEDLINE, The Cochrane Library, Web of Science, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Applied Social Sciences Index and Abstracts (ASSIA) and Education Resources Information Center (ERIC) were searched from 2002 to 2018.

Review methods

The mapping review methodology included an extensive literature search, article selection and data extraction of relevant abstracts. Findings from the mapping review informed the scope of the targeted systematic review. Methodology for the targeted systematic review included an extensive literature search informed by the mapping review, article selection, data extraction, quality appraisal and narrative synthesis.

Results

The mapping review included 413 studies with data extraction completed on abstracts. The targeted systematic review synthesised the evidence from 80 studies reported in 82 publications. During the review process, the team identified three key points at which people with intellectual disabilities potentially interacted with primary and community health-care services: identifying needs, accessing services and interaction during a consultation. In addition, there were a number of papers about interventions or innovations to improve access. Evidence from the studies was synthesised within the four clusters. Influencing factors were identified: staff knowledge/skills, joint working with learning disability services, service delivery model, uptake, appointment making, carer/support role, relationship with staff, time, accessible information and communication. The influencing factors were cross-cutting through the literature, with certain factors having more importance in certain clusters.

Limitations

The main limitation was the weak evidence base. The studies generally had small samples, had study designs that were open to potential biases and measured only short-term outcomes.

Conclusions

Health checks were found to help identify health needs and improve the care of long-term conditions. Important factors for accessing health services for adults with intellectual disabilities were consistency of care and support, staff training, communication skills and time to communicate, and provision of accessible information. Health professionals need to ensure that there is joint working between different services, clear communication and accurate record-keeping. Future research questions centre on the need to develop and value creative study designs capable of addressing the complex issues identified in the findings of the review for this complex population.

Do people with intellectual disabilities understand their prescription medication? A scoping review

Background

People with intellectual disabilities are more likely to experience poor health than the general population and are frequently prescribed multiple medications. Therefore, it is important that people with intellectual disabilities understand their medication and potential adverse effects.

Method

A scoping review explored people with intellectual disabilities' knowledge of prescription medications, their risks and how medication understanding can be improved.

Results

Ten journal articles were included. People with intellectual disabilities often lacked understanding of their medication, including its name, purpose and when and how to take it. Participants were often confused or unaware of adverse effects associated with their medication. Information was sometimes explained to carers rather than people with intellectual disabilities. Some interventions and accessible information helped to improve knowledge in people with intellectual disabilities.

Conclusion

There is a need for accessible and tailored information about medication to be discussed with people with intellectual disabilities in order to meet legal and best practice standards.

'I'm sure we made it a better study…': Experiences of adults with intellectual disabilities and parent carers of patient and public involvement in a health research study

Patient and public involvement is considered integral to health research in the United Kingdom; however, studies documenting the involvement of adults with intellectual disabilities and parent carers in health research studies are scarce. Through group interviews, this study explored the perspectives and experiences of a group of adults with intellectual disabilities and a group of parent carers about their collaborative/participatory involvement in a 3-year study which explored the effectiveness of annual health checks for adults with intellectual disabilities. Thematic analysis identified five key themes consistent across both groups; authenticity of participation, working together, generating new outcome measures, dissemination of findings and involvement in future research. Although reported anecdotally rather than originating from the analysis, increased self-confidence is also discussed. The groups' unique perspectives led to insights not previously considered by the research team which led to important recommendations to inform healthcare practice.

Psychiatric diagnoses in older people with intellectual disability in comparison with the general population: a register study

AIMS

To describe the occurrence of psychiatric diagnoses in a specialist care setting in older people with intellectual disability (ID) in relation to those found in the same age group in the general population.

METHOD

A cohort of people with ID (n = 7936), aged 55 years or more in 2012, was identified, as was an age and sex-matched cohort from the general population (n = 7936). Information regarding psychiatric diagnoses during 2002-2012 was collected from the National Patient Register, which contains records from all inpatient care episodes and outpatient specialist visits in Sweden. The mean age at the start of data collection (i.e. January 1st, 2002) was 53 years (range 44-85 years).

RESULTS

Seventeen per cent (n = 1382) of the people in the ID cohort had at least one psychiatric diagnosis recorded during the study period. The corresponding number in the general population cohort was 10% (n = 817), which translates to an odds ratio (OR) of 1.84. The diagnoses recorded for the largest number of people in the ID cohort were 'other' (i.e. not included in any of the diagnostic groups) psychiatric diagnoses (10% of the cohort had at least one such diagnosis recorded) and affective disorders (7%). In the general population cohort, the most common diagnoses were affective disorders (4%) and alcohol/substance-abuse-related disorders (4%). An increased odds of having at least one diagnosis was found for all investigated diagnoses except for alcohol/substance-abuse-related disorders (OR = 0.56). The highest odds for the ID cohort was found for diagnosis of psychotic disorder (OR = 10.4) followed by attention deficit/hyperactive disorder (OR = 3.81), dementia (OR = 2.71), personality disorder (OR = 2.67), affective disorder (OR = 1.74) and anxiety disorder (OR = 1.36). People with ID also had an increased odds of psychiatric diagnoses not included in any of these groups (OR = 8.02). The percentage of people with ID who had at least one diagnosis recorded during the study period decreased from more than 30% among those aged 55-59 years in 2012 (i.e. born 1953-1957) to approximately 20% among those aged 75+ years in 2012 (i.e. born in or before 1937).

CONCLUSIONS

Older people with ID seem to be more likely to have psychiatric diagnoses in inpatient or outpatient specialist care than their peers in the general population. If this is an effect of different disorder prevalence, diagnostic difficulties or differences in health care availability remains unknown. More research is needed to understand the diagnostic and treatment challenges of psychiatric disorders in this vulnerable group.

Long-term condition management in adults with intellectual disability in primary care: a systematic review

BACKGROUND

Adults with intellectual disabilities have higher morbidity and earlier mortality than the general population. Access to primary health care is lower, despite a higher prevalence of many long-term conditions.

AIM

To synthesise the evidence for the management of long-term conditions in adults with intellectual disabilities and identify barriers and facilitators to management in primary care.

DESIGN & SETTING

Mixed-methods systematic review.

METHOD

Seven electronic databases were searched to identify both quantitative and qualitative studies concerning identification and management of long-term conditions in adults with intellectual disability in primary care. Both the screening of titles, abstracts, and full texts, and the quality assessment were carried out in duplicate. Findings were combined in a narrative synthesis.

RESULTS

Fifty-two studies were identified. Adults with intellectual disabilities are less likely than the general population to receive screening and health promotion interventions. Annual health checks may improve screening, identification of health needs, and management of long-term conditions. Health checks have been implemented in various primary care contexts, but the long-term impact on outcomes has not been investigated. Qualitative findings highlighted barriers and facilitators to primary care access, communication, and disease management. Accounts of experiences of adults with intellectual disabilities reveal a dilemma between promoting self-care and ensuring access to services, while avoiding paternalistic care.

CONCLUSION

Adults with intellectual disabilities face numerous barriers to managing long-term conditions. Reasonable adjustments, based on the experience of adults with intellectual disability, in addition to intervention such as health checks, may improve access and management, but longer-term evaluation of their effectiveness is required.

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.

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.

Preventable Emergency Hospital Admissions Among Adults With Intellectual Disability in England

PURPOSE

Adults with intellectual disabilities experience poorer physical health and health care quality, but there is limited information on the potential for reducing emergency hospital admissions in this population. We describe overall and preventable emergency admissions for adults with vs without intellectual disabilities in England and assess differences in primary care management before admission for 2 common ambulatory care-sensitive conditions (ACSCs).

METHODS

We used electronic records to study a cohort of 16,666 adults with intellectual disabilities and 113,562 age-, sex-, and practice-matched adults without intellectual disabilities from 343 English family practices. Incident rate ratios (IRRs) from conditional Poisson regression were analyzed for all emergency and preventable emergency admissions. Primary care management of lower respiratory tract infections and urinary tract infections, as exemplar ACSCs, before admission were compared in unmatched analysis between adults with and without intellectual disabilities.

RESULTS

The overall rate for emergency admissions for adults with vs without intellectual disabilities was 182 vs 68 per 1,000 per year (IRR = 2.82; 95% CI, 2.66-2.98). ACSCs accounted for 33.7% of emergency admissions among the former compared with 17.3% among the latter (IRR = 5.62; 95% CI, 5.14-6.13); adjusting for comorbidity, smoking, and deprivation did not fully explain the difference (IRR = 3.60; 95% CI, 3.25-3.99). Although adults with intellectual disability were at nearly 5 times higher risk for admission for lower respiratory tract infections and urinary tract infections, they had similar primary care use, investigation, and management before admission as the general population.

CONCLUSIONS

Adults with intellectual disabilities are at high risk for preventable emergency admissions. Identifying strategies for better detecting and managing ACSCs, including lower respiratory and urinary tract infections, in primary care could reduce hospitalizations.
