Health services use and costs in people with intellectual disability: building a context knowledge base for evidence-informed policy

Impact of musculoskeletal disability limitations on the economic unmet dental needs in South Korea

BACKGROUND

Musculoskeletal disability (MSD) has been identified as having a negative impact on oral health. Patients with MSD have a greater burden of medical expenses and are expected to have an Economic unmet dental need (UDN). This study aimed to conduct a multifactorial analysis based on the Andersen model to determine the extent to which MSD contributes to inequitable dental care use.

METHODS

This study used data from the Korea National Health and Nutrition Survey VIII. The study population was 17,903 adults aged 19 years and older. All data were analyzed using IBM SPSS Statistics for Windows version 26 and the level of statistical significance was set at 0.05.

RESULTS

The people with MSD activity limitations were rare as only 3% in this study population. There were significant differences in sex and education as predisposing factors, income, and marital status as enabling factors, and current smoking, daily brushing, and MSD activity limitation as need factors for experiencing economic UDN. MSD activity limitation was associated with 1.5-fold increased odds of Economic UDN with a fully adjusted Anderson's Behavior Model.

CONCLUSIONS

This finding suggests poorer access to dental care among adults with MSDs owing to financial difficulties. It is necessary to explore various ways to address oral health inequalities among adults with MSD activity limitations.

Mental health problems in children with intellectual disability

Intellectual disability ranks in the top ten causes of disease burden globally and is the top cause in children younger than 5 years. 2-3% of children have an intellectual disability, and about 15% of children present with differences consistent with an intellectual disability (ie, global developmental delay and borderline intellectual functioning). In this Review, we discuss the prevalence of mental health problems, interventions to address these, and issues of access to treatment and services. Where possible, we take a global perspective, given most children with intellectual disability live in low-income and middle-income countries. Approximately 40% of children with intellectual disability present with a diagnosable mental disorder, a rate that is at least double that in children without intellectual disability. Most risk factors for poor mental health and barriers to accessing support are not unique to people with intellectual disability. With proportionate universalism as the guiding principle for reducing poor mental health at scale, we discuss four directions for addressing the mental health inequity in intellectual disability.

Intellectual disability genomics: current state, pitfalls and future challenges

Intellectual disability (ID) can be caused by non-genetic and genetic factors, the latter being responsible for more than 1700 ID-related disorders. The broad ID phenotypic and genetic heterogeneity, as well as the difficulty in the establishment of the inheritance pattern, often result in a delay in the diagnosis. It has become apparent that massive parallel sequencing can overcome these difficulties. In this review we address: (i) ID genetic aetiology, (ii) clinical/medical settings testing, (iii) massive parallel sequencing, (iv) variant filtering and prioritization, (v) variant classification guidelines and functional studies, and (vi) ID diagnostic yield. Furthermore, the need for a constant update of the methodologies and functional tests, is essential. Thus, international collaborations, to gather expertise, data and resources through multidisciplinary contributions, are fundamental to keep track of the fast progress in ID gene discovery.

Pregnancy complications and maternal birth outcomes in women with intellectual and developmental disabilities in Wisconsin Medicaid

BACKGROUND

Women with intellectual and developmental disabilities (IDD) may face greater risk for poor pregnancy outcomes. Our objective was to examine risk of maternal pregnancy complications and birth outcomes in women with IDD compared to women without IDD in Wisconsin Medicaid, from 2007-2016.

METHODS

Data were from the Big Data for Little Kids project, a data linkage that creates an administrative data based cohort of mothers and children in Wisconsin. Women with ≥1 IDD claim the year before delivery were classified as having IDD. Common pregnancy complications and maternal birth outcomes were identified from the birth record. We calculated risk ratios (RR) using log-linear regression clustered by mother. We examined outcomes grouped by IDD-type and explored interaction by race.

RESULTS

Of 177,691 women with live births, 1,032 (0.58%) had an IDD claim. Of 274,865 deliveries, 1,757 were to mothers with IDD (0.64%). Women with IDD were at greater risk for gestational diabetes (RR: 1.28, 95% CI: 1.0, 1.6), gestational hypertension (RR: 1.22, 95% CI: 1.0, 1.5), and caesarean delivery (RR 1.32, 95% CI: 1.2, 1.4) compared to other women. Adjustment for demographic covariates did not change estimates. Women with intellectual disability were at highest risk of gestational hypertension. Black women with IDD were at higher risk of gestational hypertension than expected under a multiplicative model.

CONCLUSIONS

Women with IDD have increased risk of pregnancy complications and adverse outcomes in Wisconsin Medicaid. Results were robust to adjustment. Unique patterns by IDD types and Black race warrant further exploration.

A clinical primer on intellectual disability

Between 1% and 3% of persons in general population are estimated to have some degree of intellectual disability. A diagnosis of intellectual disability is based on clinical history, level of intellectual ability and level of adaptive function. Both, the intellectual and adaptive functioning are measured using individually administered standardized tests. More than 75% of persons who have intellectual disability have mild intellectual disability and an underlying specific etiology is less likely to be identified; whereas, in a small percentage of persons with severe intellectual disability, an underlying specific biologic cause is highly likely to be identified. Genetic abnormalities, inborn errors of metabolism and brain malformations are major categories of causes identified in severe to profound intellectual disability. The initial clinical presentation and recognition depends on the severity and underlying cause of intellectual disability. The etiology, severity, cognitive abilities, and adaptive function, vary among persons with intellectual disability and need consideration in developing a treatment plan. The physician plays an essential role in the evaluation, treatment of associated medical conditions and preventive care, and in facilitating and coordinating consultative services and community based care.

A Call for Better Data on Prevalence and Health Surveillance of People With Intellectual and Developmental Disabilities

The U.S. approach to the health of people with intellectual and developmental disabilities (IDD) is fraught with paradox. The health of this population has been of longstanding concern, yet we understand their health less well than many other groups. The U.S. spends much more per person on the well-being of people with IDD compared to the general population, yet the outcomes of those expenditures are disappointing and include significant preventable health disparities. Even as expectations for people with IDD have changed to include better health and greater participation in their communities, eligibility for services that support these outcomes is rooted in expectations of dependence and poverty. This article is a call for better data that considers a series of questions to provide context for understanding the need and directions for better health surveillance of people with IDD.

Contributions of Mental and Behavioral Health Conditions to Health Service Utilization Among People With Intellectual and Developmental Disabilities in Massachusetts

Although existing evidence suggests an increased prevalence mental and behavioral health conditions for people with intellectual and developmental disabilities (IDD), little is known about health service utilization patterns related to these conditions. This study provides population-based data on hospital service utilization. Medicaid claims for people under 65 years of age in Massachusetts were used (years 2008-2013) to identify a cohort of people with IDD. Utilization of inpatient hospitalizations and outpatient Emergency Department (ED) was compared with the U.S. and MA general population through risk ratios. Findings suggest mental and behavioral health conditions were major contributors to increased utilization of inpatient and outpatient ED services and underscore the need for community-based service options that understand how to treat these conditions in people with IDD and address the myriad of related factors to identify, treat, and minimize the potential adverse life impact of these conditions for people with IDD.

Adverse drug event-related hospitalisation in persons with neurodevelopmental disorders: a state-wide retrospective cohort study

BACKGROUND

Little is known about the sociodemographic and clinical characteristics of adverse drug events (ADEs) in patients with neurodevelopmental disorders (NDD).

OBJECTIVE

The objective of this study was to describe and compare the demographic details of people with and without NDD hospitalised due to ADEs.

METHODS

The all-inclusive New South Wales Admitted Patient Data Collection from 2001 to 2014 was employed to identify ADE-related hospitalisations in patients with NDD using the International Classification of Diseases 10th revision Australian modification codes. We derived case sets specific to different clinical groups and patient characteristics and compared proportional differences between patients with and without intellectual disability using chi squared tests.

RESULTS

A total of 2173 patients with NDD were admitted for acute care of ADEs, accounting for 0.7% of all ADE-related hospitalisations. Hospitalised ADEs among patients with NDD increased by twofold over the 14-year study period. Psychotropic medications and opioid analgesic medications were leading causes of ADE-related hospitalisations in patients with NDD. Compared with their counterparts, patients with NDD were younger, experienced more socio-economic disadvantage and less private insurance coverage, suffered with less severe but different co-morbid clinical conditions and incurred more challenges in the acute hospital care setting.

CONCLUSION

Although the pattern of ADE-related hospitalisations in patients with NDD differed from that in patients without NDD, there is a lack of targeted healthcare programmes to meet their special needs. This study suggests the need for countermeasures in primary healthcare settings to reduce the burden of ADEs in this vulnerable group.

A longitudinal assessment of adherence to breast and cervical cancer screening recommendations among women with and without intellectual disability

Each year in the United States, about 4000 deaths are attributed to cervical cancer, and over 40,000 deaths are attributed to breast cancer (U.S. Cancer Statistics Working Group, 2015). The purpose of this study was to identify predictors of full, partial, and no screening for breast and cervical cancer among women with and without intellectual disability (ID) who are within the age group for screening recommended by the U.S. Preventive Service Task Force (USPSTF), while accounting for changes in recommendations over the study period. Women with ID and an age matched comparison group of women without ID were identified using merged South Carolina Medicaid and Medicare files from 2000 to 2010. The sample consisted of 9406 and 16,806 women for mammography screening and Papanicolaou (Pap) testing adherence, respectively. We estimated multinomial logistic regression models and determined that women with ID were significantly less likely than women without ID to be fully adherent compared to no screening with mammography recommendations (adjusted odds ratio [AOR]: 0.63, 95% confidence interval [CI] 0.55-0.72), and Pap testing recommendations (AOR: 0.17, 95% CI 0.16-0.19). For the 70% of women with ID for whom we had residential information, those who lived in a group home, medical facility, or supervised community living setting were more likely to be fully adherent with both preventive services than those living alone or with family members. For both outcomes, women residing in a supervised nonmedical community living setting had the highest odds of full adherence, adjusting for other covariates.

From the EBM pyramid to the Greek temple: a new conceptual approach to Guidelines as implementation tools in mental health

Guideline methods to develop recommendations dedicate most effort around organising discovery and corroboration knowledge following the evidence-based medicine (EBM) framework. Guidelines typically use a single dimension of information, and generally discard contextual evidence and formal expert knowledge and consumer's experiences in the process. In recognition of the limitations of guidelines in complex cases, complex interventions and systems research, there has been significant effort to develop new tools, guides, resources and structures to use alongside EBM methods of guideline development. In addition to these advances, a new framework based on the philosophy of science is required. Guidelines should be defined as implementation decision support tools for improving the decision-making process in real-world practice and not only as a procedure to optimise the knowledge base of scientific discovery and corroboration. A shift from the model of the EBM pyramid of corroboration of evidence to the use of broader multi-domain perspective graphically depicted as 'Greek temple' could be considered. This model takes into account the different stages of scientific knowledge (discovery, corroboration and implementation), the sources of knowledge relevant to guideline development (experimental, observational, contextual, expert-based and experiential); their underlying inference mechanisms (deduction, induction, abduction, means-end inferences) and a more precise definition of evidence and related terms. The applicability of this broader approach is presented for the development of the Canadian Consensus Guidelines for the Primary Care of People with Developmental Disabilities.

Transition to adulthood for young people with intellectual disability: the experiences of their families

Whilst the transition from school to adult roles can be challenging for any adolescent, for those with an intellectual disability it can present as a particularly difficult time both for the individual and their family. The process may involve coordinated planning, collaboration and decision-making among school staff, families and community agencies. This mixed-methods study utilised information from two cohorts: young people with Down syndrome in Western Australia (n = 190) and young people with intellectual disability (of any cause) in Queensland, Australia (n = 150). The parent-report questionnaires administered in both states comprised two parts: part 1 collected information about the individual with intellectual disability including information on health, functioning and service needs, and about specific transition related issues; and part 2 collected information about the health and well-being of their family. The majority (87 %) of parents said that they were involved in decision-making about transition planning but less than two-thirds (59.5 %) of young people were involved in this process. The three most helpful strategies indicated by parents that assisted with transition planning related to the provision of more information about financial assistance, the school transition program and the building of informal community-based supports. A number of themes emerged from the qualitative data which included parents' views and concerns about the capacity of their young adult to adapt and change to life in adulthood, their difficulty navigating services and programs, issues and challenges around their young person building connectedness, strain on family wellbeing and finances and worry about the longer term future.
