Neighbourhood deprivation, health inequalities and service access by adults with intellectual disabilities: a cross-sectional study

A study on prescriptions contributing to the risk of high anticholinergic burden in adults with intellectual disabilities: retrospective record linkage study

BACKGROUND

People with intellectual disabilities may face a disproportionate risk of experiencing high anticholinergic burden, and its negative sequalae, from a range of medications, and at younger ages than the general population, but there has been little previous study. Our aim was to determine the source of anticholinergic burden from prescribed medication.

METHODS

Retrospective matched observational study using record linkage. Adults with (n = 4,305), and without (n = 12,915), intellectual disabilities matched by age-, sex- and neighbourhood deprivation. The main outcome measure was the prescription of long-term (approximately 12 months use) anticholinergic medications overall (classified according to the Anticholinergic Risk Scale [ARS]), by drug class, individual drugs, and polypharmacy.

RESULTS

Adults with n = 1,654 (38.4%), and without n = 3,047 (23.6%), intellectual disabilities were prescribed medications long-term with anticholinergic effects. Of those on such drugs, adults with intellectual disabilities were most likely to be on central nervous system (62.6%), gastrointestinal (46.7%), and cardiovascular (28.4%) medications. They were prescribed more central nervous system, gynaecological/urinary tract, musculoskeletal, and respiratory medications, and less cardiovascular, infection, and endocrine medications than their matched comparators. Regardless of age, sex, or neighbourhood deprivation, adults with intellectual disabilities had greater odds of being prescribed antipsychotics (OR = 5.37 [4.40-6.57], p < 0.001), antiepileptics (OR = 2.57 [2.22-2.99], p < 0.001), and anxiolytics/hypnotics (OR = 1.28 [1.06-1.56], p = 0.012). Compared to the general population, adults with intellectual disabilities were more likely to be exposed to overall anticholinergic polypharmacy (OR = 1.48 [1.33-1.66], p < 0.001), and to psychotropic polypharmacy (OR = 2.79 [2.41-3.23], p < 0.001).

CONCLUSIONS

Adults with intellectual disabilities are exposed to a greater risk of having very high anticholinergic burden through polypharmacy from several classes of medications, which may be prescribed by several different prescribers. There is a need for evidence-based recommendations specifically about people with intellectual disabilities with multiple physical and mental ill-health conditions to optimise medication use, reduce inappropriate prescribing and adverse anticholinergic effects.

Dental attendance, restoration and extractions in adults with intellectual disabilities compared with the general population: a record linkage study

BACKGROUND

Oral health may be poorer in adults with intellectual disabilities (IDs) who rely on carer support and medications with increased dental risks.

METHODS

Record linkage study of dental outcomes, and associations with anticholinergic (e.g. antipsychotics) and sugar-containing liquid medication, in adults with IDs compared with age-sex-neighbourhood deprivation-matched general population controls.

RESULTS

A total of 2933/4305 (68.1%) with IDs and 7761/12 915 (60.1%) without IDs attended dental care: odds ratio (OR) = 1.42 [1.32, 1.53]; 1359 (31.6%) with IDs versus 5233 (40.5%) without IDs had restorations: OR = 0.68 [0.63, 0.73]; and 567 (13.2%) with IDs versus 2048 (15.9%) without IDs had dental extractions: OR = 0.80 [0.73, 0.89]. Group differences for attendance were greatest in younger ages, and restoration/extractions differences were greatest in older ages. Adults with IDs were more likely prescribed with anticholinergics (2493 (57.9%) vs. 6235 (48.3%): OR = 1.49 [1.39, 1.59]) and sugar-containing liquids (1641 (38.1%) vs. 2315 (17.9%): OR = 2.89 [2.67, 3.12]).

CONCLUSION

Carers support dental appointments, but dentists may be less likely to restore teeth, possibly extracting multiple teeth at individual appointments instead.

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.

Prevalence of factors associated with edentulousness (no natural teeth) in adults with intellectual disabilities

BACKGROUND

Poor oral health is largely preventable. Prevention includes toothbrushing and regular dental checks. Oral health has important consequences for general nutrition, chewing, communication, wider systemic disease, self-confidence and participation in society. This study investigated the prevalence of edentulousness (no natural teeth) in adults with intellectual disabilities (IDs) compared with the general population and associated factors.

METHODS

An adult cohort with IDs residing in Greater Glasgow and Clyde, Scotland, underwent detailed health assessments between 2002 and 2004. Between 2004 and 2006, a subsample had an oral check. Data on edentulousness in the cohort were compared with adult participants from Greater Glasgow and Clyde in the 2008 Scottish Health Survey. Within the IDs cohort, binary logistic regression analyses investigated potential relationships between edentulousness and demographic and clinical factors.

RESULTS

Five hundred sixty adults with IDs were examined [53.2% (298) male, mean age = 46.3 years, range 18-81 years] and compared with 2547 general population: edentulousness was 9% vs. 1% aged 25-34 years; 22% vs. 2% aged 35-44 years; 39% vs. 7% aged 45-54 years; 41% vs. 18% aged 55-64 years; and 76% vs. 34% aged 65-74 years. In both groups, edentulousness increased with age. After stratification for age, rates of edentulousness were consistently higher in the ID cohort. Odds ratios within age strata were not homogenous (Mantel-Haenszel test, P < 0.0001). Edentulousness was more likely in those with more severe IDs (adjusted odds ratio (AOR) = 2.36; 95% confidence interval (CI) [1.23 to 4.51]); those taking antipsychotics (AOR = 2.09; 95% CI [1.25 to 3.51]) and those living in the most deprived neighbourhoods (AOR = 2.69; 95% CI [1.11 to 6.50]). There was insufficient evidence for associations with sex, type of accommodation/support, antiepileptics, problem behaviours or autism.

CONCLUSIONS

Adults with IDs have a high prevalence of edentulousness and need supported daily oral care to reduce the need for extractions. Despite previous reports on poor oral care and the move towards person-centred care, carers and care-giving organisations need greater support to implement daily oral care. Prescribers need awareness of the potentially contributory role of antipsychotics, which may relate to xerostomia.

Intellectual Disabilities and Health Care Communication: A Continuing Education Program for Providers

Communication with others is a core human imperative; this is especially true in health care. Individuals with intellectual disabilities often face daunting challenges in both health literacy and communicating their health needs and questions. Education for professionals in specialized communication is critical in improving care for their clients with intellectual disabilities. To address this issue, an educational framework, ID-COMMUNICATE, was created to guide improved interactions between health care providers and clients with intellectual disabilities and was further developed into a continuing education program. The modules of the ID-COMMUNICATE program focus on specialized communication techniques and strategies and related professional practice issues. This program can be disseminated in a variety of ways and is easily adapted for professionals in many disciplines. [J Contin Educ Nurs. 2019;50(1):20-25.].

Patterns of objectively measured sedentary behaviour in adults with intellectual disabilities

BACKGROUND

The purpose of this study was to investigate the patterns of objectively measured sedentary behaviour in adults with intellectual disabilities.

METHODS

Baseline accelerometer data were pooled from two randomized controlled trials of lifestyle behaviour change programmes for adults with intellectual disabilities. Patterns of sedentary behaviours were computed including total volume, number, and duration of bouts and breaks.

RESULTS

Participants spent >70% of the day sedentary (8 hr), which was generally accumulated in short sedentary bouts (<10 min). Participants were engaged in significantly more sedentary time during the morning, although differences between time of day were small (mean bout duration range: 19.8-22.3 min).

CONCLUSIONS

The findings add valuable insight into the patterns of sedentary behaviours among adults with intellectual disabilities. Further research investigating the patterns and context of sedentary behaviour is required to develop targeted interventions to reduce total sedentary time in adults with intellectual disabilities.

Predictors of Emergency Room and Hospital Utilization Among Adults With Intellectual and Developmental Disabilities (IDD)

Emergency room (ER) and hospital utilization among people with intellectual and developmental disabilities (IDD) are significant contributors to rising healthcare costs. This study identifies predictors of utilization among 597 adults with IDD. Using a retrospective survey of medical charts, descriptive statistics and logistic regressions were conducted. Individual-level risk factors for ER utilization included age, number of chronic health conditions, a diagnosis of cerebral palsy or neurological disorder, mental illness, and polypharmacy. Environmental predictors included community-based supported living. Hospitalization predictors included age and number of chronic illnesses. People residing in group homes were less likely to be admitted. This study found risk factors unique to individuals with IDD that should be addressed with tailored interventions as states transition to Medicaid managed care.

Multimorbidity and lifestyle factors among adults with intellectual disabilities: a cross-sectional analysis of a UK cohort

BACKGROUND

Multimorbidity [two or more conditions in addition to intellectual disability (ID)] is known to be more common among people with ID. However, the relationship between multimorbidity and lifestyle factors is currently unknown. The aim of this study was to determine the prevalence of multimorbidity in a population of adults with ID. We also aimed to identify risk factors, including lifestyle factors, for multimorbidity in this population.

METHODS

This was a cross-sectional analysis using data from a diabetes screening study of 920 adults aged 18-74 years with ID living in Leicestershire, UK. We described comorbidities and the prevalence of multimorbidity in this population. We explored the relationship between multimorbidity and age, gender, ethnicity, severity of ID, socio-economic status, physical activity, sedentary behaviour, fruit and vegetable consumption and smoking status using multiple logistic regression.

RESULTS

The prevalence of multimorbidity was 61.2% (95% CI 57.7-64.7). Multimorbidity was independently associated with being female (P < 0.001) and severe/profound ID (P = 0.004). Increasing age was of borderline significance (P = 0.06). Individuals who were physically inactive or sedentary were more likely to be multimorbid, independent of ability to walk, age, gender, severity of ID, ethnicity and socio-economic status (adjusted OR = 1.91; 95% CI 1.23-2.97; P = 0.004 and OR = 1.98; 95% CI 1.42-2.77; P < 0.001). After excluding probable life-long conditions (autism spectrum conditions, attention deficit hyperactivity disorders, epilepsy, cerebral palsy and other paralytic syndromes) as contributing comorbidities, the effect of sedentary behaviour, but not physical activity, remained (P = 0.004). We did not observe a relationship between multimorbidity, fruit and vegetable consumption and smoking status.

CONCLUSIONS

Multimorbidity presents a significant burden to people with ID. Individuals who were physically inactive or sedentary were more likely to be multimorbid, but further work is recommended to explore the relationship between multimorbidity and lifestyle factors using standardised objective measures.

High health care costs among adults with intellectual and developmental disabilities: a population-based study

OBJECTIVE

While it is generally accepted that adults with intellectual and developmental disabilities (IDDs) use health services to a greater extent than the general population, there is remarkably little research that focuses on the costs associated with their health care. Using population-based data from adults with IDD in Ontario, this study aimed to estimate overall health care costs, classify individuals into high and non-high cost categories and describe differences in the demographics, clinical profiles and health care use patterns between these groups.

DESIGN

A retrospective cohort study based in Ontario, Canada, was conducted with the use of linked administrative health data.

METHODS

A costing algorithm developed for the general population in Ontario was applied to estimate health care costs of adults with IDD under age 65 for 2009 and 2010. Individuals were categorised into two groups according to whether their total annual health care costs were among the highest decile in the general population. These groups were compared on demographic and clinical variables, and relative mean costs for six types of health care services in the two groups were computed. In addition, we computed the proportion of individuals who remained in the high cost group over 2 years.

RESULTS

Among adults with IDD, 36% had annual health care expenditures greater than $2610 CAD (top decile of all Ontario adults under 65). These individuals were more likely to be female, to be in the oldest age groups, to live in group homes and to be receiving disability income support than individuals whose expenditures were below the high cost threshold. In addition, they had higher rates of all the physical and mental health conditions studied. Greatest health care expenses were due to hospitalisations, especially psychiatric hospitalisations, continuing care/rehabilitation costs and medication costs. The majority of individuals whose health care costs placed them in the high cost category in 2009 remained in that category a year later.

DISCUSSION

Adults with IDD are nearly 4 times as likely to incur high annual health care costs than those without IDD. Individuals with IDD and high health care costs have unique health and demographic profiles compared with adults with IDD whose annual health care costs are below the high cost threshold. Attending to their health care needs earlier in their health care trajectory may be an opportunity to improve health and reduce overall health care costs. It is important that we explore how to best meet their needs. Models proposed to meet the needs of adults with high health care costs in the general population may not apply to this unique group.

Process evaluation of a cluster-randomised controlled trial of multi-component weight management programme in adults with intellectual disabilities and obesity

BACKGROUND

Providing effective weight management to adults with intellectual disabilities is necessary to challenge the high rates of obesity. The aim of this process evaluation was to explore the feasibility of conducting a full-scale clinical trial of the TAKE 5 multi-component weight management programme.

METHODS

The study was a 12-month pilot cluster-randomised controlled trial. Adults with intellectual disabilities and obesity were randomised to either TAKE 5, which included an energy deficit diet (EDD) or Waist Winners Too, based on health education principles. A mixed-methods process evaluation was conducted focussing on the reach, recruitment, fidelity, implementation, dose (delivered/received) and context.

RESULTS

The study successfully recruited adults with intellectual disabilities. Both weight management programmes were delivered with high fidelity and implemented as intended. Only one weight management programme, TAKE 5, demonstrated potential efficacy in reducing body weight and body composition. The effectiveness was largely attributed to the EDD and social support from carers.

CONCLUSIONS

The extensive process evaluation illustrated that a full-scale trial of a multi-component programme including an EDD is feasible and an acceptable approach to weight management for adults with intellectual disabilities and obesity.

Attitudes of health care professionals toward people with intellectual disability: a comparison with the general population

BACKGROUND

Few studies have examined attitudes that may promote the social inclusion of persons with an intellectual disability (ID) among health care providers (HCPs). Yet these attitudes could impact the accessibility and quality of services provided to this population, as well as the general attitudes of HCPs. The objectives of this study were to (1) examine HCPs' pro-inclusion attitudes toward people with ID, (2) compare these to the general population's attitudes and (3) examine how HCPs' attitudes vary as a function of their socio-demographic characteristics.

METHOD

The Attitudes Toward Intellectual Disability Questionnaire was administered to 367 HCPs and a representative sample of the Québec population (N = 1605).

RESULTS

Results indicated that at least half of HCPs displayed positive attitudes, that is, attitudes that are compatible with notions of social inclusion and equal rights, toward individuals with ID. Positive attitudes were less frequently observed for the Interaction and the Sensitivity or tenderness factors measured by the Attitudes Toward Intellectual Disability Questionnaire. In comparison with the general population, HCPs exhibited more positive attitudes on the Knowledge of causes and Sensitivity or tenderness factors and less positive attitudes on the Interaction factor. HCPs who regarded themselves as more knowledgeable about ID and those who reported higher quality contacts or interactions with persons with ID expressed attitudes that were more favourable toward social inclusion.

CONCLUSIONS

In addition to providing general knowledge about ID and the specific health care needs of individuals with ID, training programmes should also promote interactions with this population. Further studies are needed to document HCPs' pro-inclusion attitudes toward people with ID and to assess the impact of interventions on these attitudes.

Correlates of objectively measured sedentary time in adults with intellectual disabilities

Sedentary behaviour is an independent risk factor for adverse health conditions. Adults with intellectual disabilities spend a high proportion of their day engaged in sedentary behaviour, however, there is limited evidence on potential correlates of objectively measured sedentary behaviour in this population group. In Glasgow, UK from July to September 2017, a secondary analysis of pooled baseline accelerometer data from two randomised controlled trials of lifestyle behaviour change programmes was conducted. Backwards linear regression was used to investigate the associations between demographic, biological, and environmental correlates and objective measure of sedentary behaviour (percentage of time spent sedentary). One-hundred and forty-three participants provided valid accelerometer data. Mean percentage time spent sedentary (adjusted for wear time) was 72.9% [Standard Deviation (SD) = 8.7] per day. In the final model, physical and mental health problems were significantly (p < 0.05) associated with increased percentage time spent sedentary. This is the first study to provide evidence on multi-level, demographic, biological, and environmental correlates of objectively measured sedentary behaviour in adults with intellectual disabilities. To inform the development of interventions to modify sedentary behaviours in adults with intellectual disabilities, further research is required including a wide range of socio-ecological correlates.

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.

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.

Equity in social care for people with intellectual disabilities? A cross-sectional study examining the distribution of social care funding across local authorities in England

Many people with intellectual disabilities rely on social care provision, though little research has looked at how access to such provision is distributed nationally. Evidence from children's services suggests that there are large discrepancies between local authorities (LAs) in terms of the resources expended on interventions with children and families, which can be explained by variations linked to geographical location, namely the level of socioeconomic deprivation between LAs, constituting 'child welfare inequalities'. This study explored relationships between resources allocated to community services for people with intellectual disabilities in England and geographical factors, including deprivation, rurality and political leadership in the LAs where these individuals reside. Data were sourced from publicly available reports of spending of 151 English councils with adult social services responsibilities (CASSRs) for 2013-2014 and from CASSR index of multiple deprivation (IMD) scores and rurality for the same period. We found that more deprived LAs supported more people with intellectual disabilities, per 100,000 of population. We did not find effects for rurality or political party. However, it was not the case that more deprived LAs allocated more funds for expenditure on this group. These findings point to inequities in the distribution of social care resources for people with intellectual disabilities in England, as although more deprived LAs support more people with intellectual disabilities, they do not spend proportionally larger sums of money on this group. We discuss possible explanations for these findings and highlight the need for more research, particularly investigations about allocation of resources within LAs and more detailed explorations of how structural factors such as socioeconomic status of service users effects service access at the local level.

Process evaluation of the Walk Well study: a cluster-randomised controlled trial of a community based walking programme for adults with intellectual disabilities

BACKGROUND

Walking interventions can be effective in encouraging sedentary populations to become more active; however, limited research has explored the effectiveness of walking interventions for adults with intellectual disabilities. This process evaluation explored the delivery of a community based walking intervention for adults with intellectual disabilities.

METHODS

Walk Well was a single-blind cluster randomised controlled trial of a 12-week physical activity consultation-led walking intervention. 102 participants were randomised to the Walk Well intervention or a waiting list control group. Participants in the intervention group received three physical activity consultations with a walking advisor at baseline, 6 & 12-weeks. They were encouraged to use a pedometer to set goals and monitor their daily step count. Primary outcome was change in daily step count at 12-weeks. Process evaluation measures included qualitative interviews with key stakeholders (n = 6) and quantifiable data collected as part of the intervention. Additional process data were extracted from a sub-set of qualitative interviews with participants and carers (n = 20). Data were analysed for process information related to context, recruitment and retention, reach, implementation, and fidelity.

RESULTS

Walk Well was not effective in significantly increasing levels of physical activity. The process evaluation did, however, highlight several important areas for consideration in future studies, including: a successful recruitment and retention strategy reaching a representative sample of adults with intellectual disabilities in the community; feasible and (for most) enjoyable methods of engaging adults with intellectual disabilities in activities to support behaviour change; potential need for greater intervention duration and frequency of contact; advantages and disadvantages of using pedometers as a behaviour change tool; the need for strategies which engage carers in supporting participants; and the complex issue of 'freedom of choice' in relation to lifestyle behaviours and study participation.

CONCLUSIONS

Walking interventions for adults with intellectual disabilities can be feasibly delivered in the community in relation to reach, recruitment, retention and intervention fidelity. More intensive intervention methods need to be explored as well as strategies to engage and motivate carers in their support of participants.

Organising healthcare services for persons with an intellectual disability

BACKGROUND

When compared to the general population, persons with an intellectual disability have lower life expectancy, higher morbidity, and more difficulty finding and obtaining healthcare. Organisational interventions are used to reconfigure the structure or delivery of healthcare services. This is the first update of the original review.

OBJECTIVES

To assess the effects of organisational interventions of healthcare services for the mental and physical health problems of persons with an intellectual disability.

SEARCH METHODS

For this update we searched CENTRAL, MEDLINE, EMBASE, CINAHL and other databases, from April 2006 to 4 September 2015. We checked reference lists of included studies and consulted experts in the field.

SELECTION CRITERIA

Randomised controlled trials of organisational interventions of healthcare services aimed at improving care of mental and physical health problems of adult persons with an intellectual disability.

DATA COLLECTION AND ANALYSIS

We employed standard methodological procedures as outlined in the Cochrane Handbook of Systematic Reviews of Interventions, in addition to specific guidance from the Cochrane Effective Practice and Organisation of Care (EPOC) Group.

MAIN RESULTS

We identified one new trial from the updated searches.Seven trials (347 participants) met the selection criteria. The interventions varied but had common components: interventions that increased the intensity and frequency of service delivery (4 trials, 200 participants), community-based specialist behaviour therapy (1 trial, 63 participants), and outreach treatment (1 trial, 50 participants). Another trial compared two active arms (traditional counselling and integrated intervention for bereavement, 34 participants).The included studies investigated interventions dealing with the mental health problems of persons with an intellectual disability; none focused on physical health problems. Four studies assessed the effect of organisational interventions on behavioural problems for persons with an intellectual disability, three assessed care giver burden, and three assessed the costs associated with the interventions. None of the included studies reported data on the effect of organisational interventions on adverse events. Most studies were assessed as having low risk of bias.It is uncertain whether interventions that increase the frequency and intensity of delivery or outreach treatment decrease behavioural problems for persons with an intellectual disability (two and one trials respectively, very low certainty evidence). Behavioural problems were slightly decreased by community-based specialist behavioural therapy (one trial, low certainty evidence). Increasing the frequency and intensity of service delivery probably makes little or no difference to care giver burden (MD 0.03, 95% CI -3.48 to 3.54, two trials, moderate certainty evidence). It is uncertain whether outreach treatment makes any difference for care giver burden (one trial, very low certainty evidence). There was very limited evidence regarding costs, with low to very low certainty evidence for the different interventions.

AUTHORS' CONCLUSIONS

There is very limited evidence on the organisation of healthcare services for persons with an intellectual disability. There are currently no well-designed studies focusing on organising the health services of persons with an intellectual disability and concurrent physical problems. There are very few studies of organisational interventions targeting mental health needs and the results of those that were found need corroboration. There is an urgent need for high-quality health services research to identify optimal health services for persons with an intellectual disability and concurrent physical problem.

Effectiveness of a walking programme to support adults with intellectual disabilities to increase physical activity: walk well cluster-randomised controlled trial

BACKGROUND

Programs to change health behaviours have been identified as one way to reduce health inequalities experienced by disadvantaged groups. The objective of this study was to examine the effectiveness of a behaviour change programme to increase walking and reduce sedentary behaviour of adults with intellectual disabilities.

METHODS

We used a cluster randomised controlled design and recruited participants over 18 years old and not regularly involved in physical activity from intellectual disabilities community-based organisations. Assessments were carried out blind to allocation. Clusters of participants were randomly allocated to the Walk Well program or a 12-week waiting list control. Walk Well consisted of three face-to-face physical activity consultations incorporating behaviour change techniques, written resources for participants and carers, and an individualised, structured walking programme. The primary outcome measured with accelerometers was change in mean step count per day between baseline and 12 weeks. Secondary outcomes included percentage time per day sedentary and in moderate-vigorous physical activity (MVPA), body mass index (BMI), and subjective well being.

RESULTS

One hundred two participants in 50 clusters were randomised. 82 (80.4%) participants completed the primary outcome. 66.7% of participants lived in the most deprived quintile on the Scottish Index of Multiple Deprivation. At baseline, participants walked 4780 (standard deviation 2432) steps per day, spent 65.5% (standard deviation 10.9) of time sedentary and 59% percent had a body mass in the obesity range. After the walking programme, the difference between mean counts of the Walk Well and control group was 69.5 steps per day [95% confidence interval (CI) -1054 to 1193.3]. There were no significant between group differences in percentage time sedentary 1.6% (95% CI -2.984 to 6.102), percentage time in MVPA 0.3% (95% CI -0.7 to 1.3), BMI -0.2 kg/m(2) (95% CI -0.8 to 0.4) or subjective well-being 0.3 (95% CI -0.9 to 1.5).

CONCLUSIONS

This is the first published trial of a walking program for adults with intellectual disabilities. Positively changing physical activity and sedentary behaviours may require more intensive programmes or upstream approaches to address the multiple social disadvantages experienced by adults with intellectual disabilities. Since participants spent the majority of their time sedentary, home-based programmes to reduce sitting time may be a viable health improvement approach.

Multiple physical and mental health comorbidity in adults with intellectual disabilities: population-based cross-sectional analysis

BACKGROUND

Adults with intellectual disabilities have increased early mortality compared with the general population. However, their extent of multimorbidity (two or more additional conditions) compared with the general population is unknown, particularly with regards to physical ill-health, as are associations between comorbidities, neighbourhood deprivation, and age.

METHODS

We analysed primary health-care data on 1,424,378 adults registered with 314 representative Scottish practices. Data on intellectual disabilities, 32 physical, and six mental health conditions were extracted. We generated standardised prevalence rates by age-groups, gender, and neighbourhood deprivation, then calculated odds ratio (OR) and 95 % confidence intervals (95 % CI) for adults with intellectual disabilities compared to those without, for the prevalence, and number of condition.

RESULTS

Eight thousand fourteen (0.56 %) had intellectual disabilities, of whom only 31.8 % had no other conditions compared to 51.6 % without intellectual disabilities (OR 0.26, 95 % 0.25-0.27). The intellectual disabilities group were significantly more likely to have more conditions, with the biggest difference found for three conditions (10.9 % versus 6.8 %; OR 2.28, 95 % CI 2.10-2.46). Fourteen physical conditions were significantly more prevalent, and four cardiovascular conditions occurred less frequently, as did any cancers, and chronic obstructive pulmonary diseases. Five of the six mental health conditions were significantly more prevalent. For the adults with intellectual disabilities, no gradient was seen in extent of multimorbidity with increasing neighbourhood deprivation; indeed findings were similar in the most affluent and most deprived areas. Co-morbidity increased with age but is highly prevalent at all ages, being similar at age 20-25 to 50-54 year olds in the general population.

CONCLUSIONS

Multi-morbidity burden is greater, occurs at much earlier age, and the profile of health conditions differs, for adults with intellectual disabilities compared with the general population. There is no association with neighbourhood deprivation; people with intellectual disabilities need focussed services irrespective of where they live, and at a much earlier age than the general population. They require specific initiatives to reduce inequalities.

The relationship between area deprivation and contact with community intellectual disability psychiatry

BACKGROUND

People with intellectual disabilities (ID) have high rates of psychiatric illness and are known to live in more deprived areas than the general population. This study investigated the relationship between area deprivation and contact with ID psychiatry.

METHOD

Psychiatric case notes and electronic records were used to identify all patients who had face-to-face contact with community ID psychiatric services over 1 year in the North East Community Health Partnership of Greater Glasgow and Clyde (estimated population 177,867). The Scottish Index of Multiple Deprivation (SIMD) were determined for the patient sample and for the general population living in the same area.

RESULTS

Between 1 June 2012 and 1 June 2013, 184 patients were seen by ID psychiatry over a total of 553 contacts, with valid SIMD data for 179 patients and 543 contacts. Fifty-two per cent of patients (n = 93) lived in the most deprived SIMD decile, and 90.5% (n = 152) in the lowest 5 deciles. Compared with the general population, there were significantly more patients than expected living in the most deprived decile (Fisher's Exact test, P = 0.009) and in the most deprived 5 deciles (Fisher's Exact test, P = 0.001). The median number of contacts was 2 (interquartile range = 1-3). There was no significant association between the number of contacts and SIMD decile. Forty-eight point one per cent (n = 261) of all contacts were with patients living in the most deprived decile and 88.6% (n = 481) in the most deprived 5 deciles. This was significantly more than expected compared with general population data (Fisher's Exact test, P = 0.008 and Fisher's Exact test, P ≤ 0.001).

CONCLUSIONS

In the area under study, contact with ID psychiatry was greater in more deprived areas. Given the high psychiatric morbidity of people with ID, if services do not adjust for deprivation, this may lead to further discrimination in an already disadvantaged population.

A systematic review of hospital experiences of people with intellectual disability

BACKGROUND

People with intellectual disability are at risk of poor hospital experiences and outcomes. The aims were to conduct a content and quality review of research into the acute hospital experiences of both people with intellectual disabilities and their carers, and to identify research gaps.

METHOD

A systematic search was conducted of primary research between 2009 and 2013 that addressed the experiences of the target group in general acute care hospitals. Quality appraisal tools yielded scores for quantitative and qualitative studies, and overarching themes across studies were sought.

RESULTS

Sixteen studies met inclusion criteria. Quality scores were 6/8 for a survey, and 2/11-9/11 (mean =5.25) for qualitative studies/components. Content analysis revealed seven over-arching themes covering individuals' fear of hospital encounters, carer responsibilities, and problems with delivery of care in hospitals including staff knowledge, skills and attitudes.

CONCLUSIONS

Our review of eligible papers revealed that despite 20 years of research and government initiatives, people with intellectual disability continue to have poor hospital experiences. The need for research to identify and investigate care at specific points of encounter across a hospital journey (such as admission, diagnostic testing, placement on a ward, and discharge) as well as to include people with a diversity of disabilities is discussed in terms of potential to influence policy and practice across health and disability sectors.

Social exclusion and people with intellectual disabilities: a rural-urban comparison

BACKGROUND

Research suggests that social exclusion is a problem both for people with intellectual disabilities (ID) and for people living in rural areas. This may give rise to a double disadvantage for people with ID living in rural areas. Conversely, aspects of rural life such as community spirit and social support may protect against social exclusion in this population. This study was designed to compare a number of measures of social exclusion in adults with ID living in rural and urban areas, with the aim of identifying whether a double disadvantage exists.

METHOD

Adults with ID were recruited from a rural and an urban area in Scotland. Participants participated in a face-to-face interview and their medical notes were accessed. Social exclusion was investigated using a number of measures comprising: daytime opportunities and physical access to community facilities (using part of the British Institute of Learning Disabilities questionnaire), recent contact with others and the quality of personal relationships (using a modified Interview Measure of Social Relationships questionnaire) and area deprivation by postcode (using the Scottish Index of Multiple Deprivation). The data were analysed using a series of binary logistic regression models that adjusted for variables including age, gender, level of ID, mental illhealth and common physical co-morbidities.

RESULTS

A representative sample of adults with ID from rural (n = 39) and urban (n = 633) areas participated. Participants from rural areas were significantly more likely to have any regular daytime opportunity [odds ratio (OR) = 10.8, 95% CI = 2.3-51.5] including employment (OR = 22.1, 95% CI = 5.7-85.5) and attending resource centres (OR = 6.7, 95% CI = 2.6-17.2) than were participants from urban areas. They were also more likely to have been on holiday (OR = 17.8, 95% CI = 4.9-60.1); however, were less likely to use community facilities on a regular basis. Participants from urban and rural areas had a similar number of contacts with other people in a wide range of situations, but the quality of relationships may have been less close in rural areas. Finally, participants lived in significantly less deprived areas when in rural compared with urban areas (Mann-Whitney U = 7826, Z = -3.675, P ≤ 0.001).

CONCLUSIONS

These results suggest that adults with ID living in rural areas have better opportunities and live in less deprived areas than adults with ID living in urban areas. However, they may not hold such positive or close relationships, and this may be important when considering the subjective experience of social exclusion.
