Disability, health, and multiple chronic conditions among people eligible for both Medicare and Medicaid, 2005-2010.

INTRODUCTION: People who are eligible for both Medicare and Medicaid (dual eligibles) and who have disabilities and multiple chronic conditions (MCC) present challenges for treatment, preventive services, and cost-effective access to care within the US health system. We sought to better understand dual eligibles and their association with MCC, accounting for sociodemographic factors inclusive of functional disability category. METHODS: Medical Expenditure Panel Survey (MEPS) data for 2005 through 2010 were stratified by ages 18 to 64 and 65 or older to account for unique subsets of dual eligibles. Prevalence of MCC was calculated for those with physical disabilities, physical plus cognitive disabilities, and all others, accounting for sociodemographic and health-related factors. Adjusted odds for having MCC were calculated by using logistic regression. RESULTS: Of dual eligibles aged 18 to 64, 53% had MCC compared with 73.5% of those aged 65 or older. Sixty-five percent of all dual eligibles had 2 or more chronic conditions, and among dual eligibles aged 65 or older with physical disabilities and cognitive limitations, 35% had 4 or more, with hypertension and arthritis the most common conditions. Dual eligibles aged 18 to 64 who had a usual source of medical care had a 127% increased likelihood of having MCC compared with those who did not have a usual source of care. CONCLUSION: Attention to disability can be a component to helping further understand the relationship between health and chronic conditions for dual eligible populations and other segments of our society with complex health and medical needs.

Health characteristics and outcomes of caregivers in the United States: An Analysis of the 2017 Health Information National Trends Survey (HINTS).

BACKGROUND: Caregivers are essential for assisting people with disabilities to fully participate in their communities. Past research has primarily focused on family caregivers in the U.S. providing care to older adults rather than children and adults with disabilities. OBJECTIVE: This paper examines the demographic and health characteristics of caregivers of children and adults with disabilities across the lifespan using data from the 2017 Health Information National Trends Survey (HINTS). METHODS: Chi square, t-test, linear and logistic regression analyses show differences between caregivers and non-caregivers related to gender, age, employment, and specific health outcomes. RESULTS: Of 3285 respondents, 18% self-identified as caregivers of children or adults with disabilities (n = 546). Almost one-third of all caregivers reported being diagnosed with depression or an anxiety disorder as compared to one-fifth of non-caregivers. Psychological distress was associated with an increased risk for a diagnosis of depression/anxiety. We also found that distress decreased with age when controlling for other factors. CONCLUSION: This paper increases knowledge of a growing segment of family caregivers providing care for members with disabilities across the lifespan. Research and policy needs are discussed.

Provider continuity and reasons for not having a provider among persons with and without disabilities.

BACKGROUND: Persons with disabilities experience health disparities while having usual providers more frequently than persons without disabilities. Provider discontinuity may help to explain these paradoxical findings, but research on the topic is nascent. OBJECTIVE: To provide initial insight into whether persons with disabilities more frequently experience provider discontinuity than persons without disabilities. METHODS: Pooled 2-year data from panels 14-16 (2009-2012) of the Medical Expenditure Panel Survey were examined. Working-age adults (18-64) were categorized as having no disability, basic disabilities, or complex disabilities. Persons were categorized having provider continuity (provider throughout the period) or discontinuity (gaining or losing providers during the period). χ2 and multinomial logistic regressions were used to examine outcomes by disability status. RESULTS: Persons with complex disabilities more frequently experienced continuity (83.7%) than persons without disabilities and those with basic disabilities (60.7% and 65.6%, respectively, p < 0.001). Seldom or never being sick was the most frequently reported reason for not having a usual provider; more persons without disabilities (64%) reported this reason than persons with disabilities (basic: 41.9%, p < 0.001; complex: 26.6%, p = 0.001). Persons with disabilities more frequently reported visiting different providers for different needs and not having a usual provider due to the costs of medical care than persons without disabilities. CONCLUSIONS: Future research needs to examine the influence of continuity on healthcare disparities among persons with complex disabilities. Policies and practice must be attentive to how proposed changes to the healthcare system potentially reduce access to care among persons with disabilities.

Characteristics of Medicare Beneficiaries With Intellectual or Developmental Disabilities.

Gaps in knowledge and systematic tracking of the prevalence of intellectual and developmental disabilities (IDD) and characteristics that may affect the health of this disability group limits our ability to address the health disparities they experience in comparison to people without disability. The purpose of this study is to begin to fill one relevant critical gap in knowledge: understanding the demographics and health outcomes of adults with IDD who receive services under Medicare Fee-for-Service (FFS), many of who are also eligible for Medicaid. Using 2016 Medicare administrative claims, we examined the prevalence and characteristics of five diagnosis groups of IDD, in those under 65 and those 65 and over, as well as their health outcomes. We found that the IDD Medicare FFS group had high prevalence rates for chronic physical and mental health conditions, overuse of emergency departments, and high rate of 30-day readmission. These findings highlight the need for evidence-based health care coordination, improved and increased public health interventions, and continued surveillance.

The relationship between employment and health and health care among working-age adults with and without disabilities in the United States.

Purpose: To better understand the relationship between employment and health and health care for people with disabilities in the United States (US). Methods: We pooled US Medical Expenditure Panel Survey (2004-2010) data to examine health status, and access to health care among working-age adults, comparing people with physical disabilities or multiple disabilities to people without disabilities, based on their employment status. Logistic regression and least squares regression were conducted, controlling for sociodemographics, health insurance (when not the outcome), multiple chronic conditions, and need for assistance. Results: Employment was inversely related to access to care, insurance, and obesity. Yet, people with disabilities employed in the past year reported better general and mental health than their peers with the same disabilities who were not employed. Those who were employed were more likely to have delayed/forgone necessary care, across disability groups. Part-time employment, especially for people with multiple limitations, was associated with better health and health care outcomes than full-time employment. Conclusion: Findings highlight the importance of addressing employment-related causes of delayed or foregone receipt of necessary care (e.g., flex-time for attending appointments) that exist for all workers, especially those with physical or multiple disabilities. Implications for rehabilitation These findings demonstrate that rehabilitation professionals who are seeking to support employment for persons with physical limitations need to ensure that overall health concerns are adequately addressed, both for those seeking employment and for those who are currently employed. Assisting clients in prioritizing health equally with employment can ensure that both areas receive sufficient attention. Engaging with employers to develop innovative practices to improve health, health behaviors and access to care for employees with disabilities can decrease turnover, increase productivity, and ensure longer job tenure.

Hearing loss and associated medical conditions among individuals 65 years and older.

BACKGROUND: Hearing loss is prevalent, but few studies have investigated its associations with common medical conditions. OBJECTIVE: The objective was to assess the prevalence of medical conditions among individuals with hearing loss, compared to those without hearing loss, in people aged 65 years and older. METHODS: The National Health Interview Survey (NHIS) collects data on a variety of health-related topics, including disability. Three years of NHIS data (2011-2013; unweighted n = 53,111) were pooled to examine subpopulations of individuals with hearing loss. Comparisons were made between adults aged 65 and older with, and without, self-reported hearing loss. Statistical analysis included descriptive frequencies, Chi-square tests, and multiple logistic regressions. The outcomes of interest included self-reported diagnosis of arthritis, cardiovascular disease, diabetes, high blood pressure, emphysema, stroke, cancer, asthma, multiple chronic conditions, health status, and obesity. RESULTS: Hearing loss prevalence was nearly 37%. After adjusting for sociodemographics, smoking status, and disability, hearing loss was independently associated with the following conditions: arthritis (OR 1.41; 1.27-1.57), cancer (OR 1.35; 1.21-1.5), cardiovascular disease (OR 1.48; 1.33-1.66), diabetes (OR 1.16; 1.03-1.31), emphysema (OR 1.41; 1.14-1.74), high blood pressure (OR 1.29; 1.17-1.43), and stroke (OR 1.39; 1.12-1.66). There was an association with worse health status over the past year (OR 1.5 (1.3-1.73). CONCLUSIONS: Hearing loss among older individuals is independently associated with increased disease burden and poorer self-reported health. Future studies are needed to investigate the mechanistic nature of these associations, and whether improved access to hearing healthcare surveillance can reduce the overall health burden among these individuals.

Introducing the Adults with Chronic Healthcare Needs (ACHCN) definition and screening instrument: Rationale, supporting evidence and testing.

BACKGROUND: Among working age adults in the United States, there is a large, heterogeneous population that requires ongoing and elevated levels of healthcare and related services. At present, there are conflicting approaches to the definition and measurement of this population in health services research. OBJECTIVE: An expert panel was convened by the National Institutes of Health with the objective of developing a population-level definition of Adults with Chronic Healthcare Needs (ACHCN). In addition, the panel developed a screening instrument and methods for its use in health surveys to identify and stratify the population consistently. METHODS: The panel employed multiple methods over the course of the project, including scoping literature reviews, quantitative analyses from national data sources and cognitive testing. RESULTS: The panel defined the ACHCN population as "Adults (age 18-65) with [1] ongoing physical, cognitive, or mental health conditions or difficulties functioning who [2] need health or related support services of a type or amount beyond that needed by adults of the same sex and similar age." The screener collects information on chronic health conditions, functional difficulties, and elevated use of or unmet need for healthcare services. CONCLUSIONS: Adapted from the Maternal and Child Health Bureau definition that identifies Children with Special Healthcare Needs, aligned with the ACS-6 disability measure, and consistent with the HHS Multiple Chronic Condition Framework, this definition and screener provide the research community with a common denominator for the identification of ACHCN.

At the intersection of chronic disease, disability and health services research: A scoping literature review.

BACKGROUND: There is a concerted effort underway to evaluate and reform our nation's approach to the health of people with ongoing or elevated needs for care, particularly persons with chronic conditions and/or disabilities. OBJECTIVE: This literature review characterizes the current state of knowledge on the measurement of chronic disease and disability in population-based health services research on working age adults (age 18-64). METHODS: Scoping review methods were used to scan the health services research literature published since the year 2000, including medline, psycINFO and manual searches. The guiding question was: "How are chronic conditions and disability defined and measured in studies of healthcare access, quality, utilization or cost?" RESULTS: Fifty-five studies met the stated inclusion criteria. Chronic conditions were variously defined by brief lists of conditions, broader criteria-based lists, two or more (multiple) chronic conditions, or other constructs. Disability was generally assessed through ADLs/IADLs, functional limitations, activity limitations or program eligibility. A smaller subset of studies used information from both domains to identify a study population or to stratify it by subgroup. CONCLUSIONS: There remains a divide in this literature between studies that rely upon diagnostically-oriented measures and studies that instead rely on functional, activity or other constructs of disability to identify the population of interest. This leads to wide ranging differences in population prevalence and outcome estimates. However, there is also a growing effort to develop methods that account for the overlap between chronic disease and disability and to "segment" this heterogeneous population into policy or practice relevant subgroups.

Prevalence and reasons for delaying and foregoing necessary care by the presence and type of disability among working-age adults.

BACKGROUND: While it is commonly accepted that disparities in unmet need for care vary by age, race/ethnicity, income, education, and access to care, literature documenting unmet needs experienced by adults with different types of disabilities is developing. OBJECTIVE: The main objective was to determine whether subgroups of people with disabilities are more likely than people without disabilities to delay/forgo necessary care, in general and among the insured. METHODS: We used pooled Medical Expenditure Panel Survey data (2004-2010) to examine delaying or forgoing medical, dental, and pharmacy care among five disability subgroups (physical, cognitive, visual, hearing, multiple) and the non-disabled population. Logistic regression was conducted to examine delayed/forgone care, controlling for sociodemographic, health, and health care factors. RESULTS: Over 13% of all working-age adults delayed/forwent necessary care; lack of insurance was the strongest predictor of unmet needs. Among the insured, disability subgroups were greater than two times more likely to report delayed/forgone care than adults without disabilities. Insured working-age adults with multiple chronic conditions and those with ADL/IADL assistance needs had higher odds of delayed or forgone care than their peers without these characteristics. Reasons related to affordability were most often listed as leading to unmet needs, regardless of disability. CONCLUSION: Although insurance status most strongly predicted unmet needs for care, many people with insurance delayed/forewent necessary care. Even among the insured, all disability subgroups had significantly greater likelihood of having to delay/forgo care than those without disabilities. Differences also existed between the disability subgroups. Cost was most frequently cited reason for unmet needs.

Asthma and asthma-related health care utilization among people without disabilities and people with physical disabilities.

BACKGROUND: Previous research has shown that people with disabilities have higher rates of some chronic diseases and receive poorer disease-specific care than their counterparts without disabilities. Yet, little is known about the relationship between asthma and disability. OBJECTIVE: This study examines whether differences in the prevalence of asthma, asthma flare, and asthma-related measures of health care quality, utilization and cost exist among people with physical limitations (PL) and without any limitations. METHODS: Data from the 2004-2010 Medical Expenditure Panel Survey were pooled to compare outcomes for working-age adults (18-64) with PL to those with no limitations. RESULTS: People with PL had higher rates of asthma (13.8% vs. 5.9%, p < 0.001) and recent asthma flare (52.6% vs. 39.6%, p < 0.001) than people without limitations. There were no differences in health care quality, utilization or cost between people with PL and people without limitations in multivariate analyses. CONCLUSIONS: Although there are no differences in asthma-related quality or utilization of health care, people with PL have poorer asthma control than people without limitations. Research is needed to determine what factors (e.g., focus on other acute ailments, perceptions that asthma control cannot improve) are related to this outcome. Future research must also examine differences in asthma severity, and its impact on asthma control and health care-related outcomes, among people with and without disabilities.

Testing the Feasibility of a Passive and Active Case Ascertainment System for Multiple Rare Conditions Simultaneously: The Experience in Three US States.

BACKGROUND: Owing to their low prevalence, single rare conditions are difficult to monitor through current state passive and active case ascertainment systems. However, such monitoring is important because, as a group, rare conditions have great impact on the health of affected individuals and the well-being of their caregivers. A viable approach could be to conduct passive and active case ascertainment of several rare conditions simultaneously. This is a report about the feasibility of such an approach. OBJECTIVE: To test the feasibility of a case ascertainment system with passive and active components aimed at monitoring 3 rare conditions simultaneously in 3 states of the United States (Colorado, Kansas, and South Carolina). The 3 conditions are spina bifida, muscular dystrophy, and fragile X syndrome. METHODS: Teams from each state evaluated the possibility of using current or modified versions of their local passive and active case ascertainment systems and datasets to monitor the 3 conditions. Together, these teams established the case definitions and selected the variables and the abstraction tools for the active case ascertainment approach. After testing the ability of their local passive and active case ascertainment system to capture all 3 conditions, the next steps were to report the number of cases detected actively and passively for each condition, to list the local barriers against the combined passive and active case ascertainment system, and to describe the experiences in trying to overcome these barriers. RESULTS: During the test period, the team from South Carolina was able to collect data on all 3 conditions simultaneously for all ages. The Colorado team was also able to collect data on all 3 conditions but, because of age restrictions in its passive and active case ascertainment system, it was able to report few cases of fragile X syndrome. The team from Kansas was able to collect data only on spina bifida. For all states, the implementation of an active component of the ascertainment system was problematic. The passive component appears viable with minor modifications. CONCLUSIONS: Despite evident barriers, the joint passive and active case ascertainment of rare disorders using modified existing surveillance systems and datasets seems feasible, especially for systems that rely on passive case ascertainment.

Psychotropic medication use among Kansas Medicaid youths with disabilities.

Knowledge of current patterns of psychotropic medication use by disabled youths is an important starting point for targeting future efforts to improve prescribing practices. This study provides a retrospective, descriptive analysis of the prevalence and patterns of psychotropic medication among 1022 Kansas Medicaid youths in 2001 who were enrolled with either Supplemental Security Income (SSI) or Medically Needy benefits and who were having clearly defined mental and neurological disabilities. Rates of psychotropic medication use were generally higher for the Medically Needy than for the SSI youths: Central nervous system (CNS) stimulants (24.6% versus 20.0%), antidepressants (30.9% versus 13.7%), anticonvulsants (22.0% versus 13.9%), and antipsychotics (23.3% versus 11.5%). Use of the four major drug classes varied among children with attention-deficit/hyperactivity disorder (ADHD) and disruptive disorders, pervasive developmental disabilities, mental retardation (MR) and learning disabilities, mood and anxiety disorders, and adjustment disorders. Future work should explore the appropriateness and effectiveness of these medications within specifically targeted subgroups.

Diagnosis isn't enough: Understanding the connections between high health care utilization, chronic conditions and disabilities among U.S. working age adults.

BACKGROUND: Under the ACA, new programs are being developed to enhance care coordination and reduce health care costs among people with chronic conditions, disabilities, and high utilization of health care. However, the relationships between these groups are not well understood. OBJECTIVES: Our aims were to (1) identify high utilizers of health care in the U.S. working age (18-64) population, (2) examine the overlap between this group and people with chronic conditions and/or disabilities, (3) identify predictors of high service use or cost among these subpopulations, and (4) recommend approaches for stratification of individuals with high health care utilization. METHODS: Using pooled national data from the Medical Expenditure Panel Survey (2006-2008), we created indices to identify elevated or high utilization and cost groups. We performed descriptive analyses, bivariate comparisons and multivariate analyses to examine the relations between these populations and individuals with chronic conditions and/or disabilities. RESULTS: While the large majority of persons with high use/cost had chronic conditions, the minority of persons with chronic conditions had high health care utilization. However, among persons with chronic conditions, disability was a significant predictor of high utilization. Annual expenditures were significantly elevated among people with disabilities, particularly when activities of daily living were limited. CONCLUSIONS: We conclude that medical diagnosis alone is insufficient for the development of eligibility criteria for, or the evaluation of, programs intended to better the delivery or coordination of services for high utilizers of health care services. New approaches are needed to assess functional limitations and identify ongoing needs for services and supports.

A comparison of two weight management programs for adults with mobility impairments.

BACKGROUND: Individuals with physical disabilities experience disparities in obesity; yet few interventions have incorporated accommodations necessary for weight loss in this population. OBJECTIVE/HYPOTHESIS: This project compared the effectiveness of two weight loss interventions among individuals with physical disabilities. METHODS: Adults with physical disabilities who were overweight or obese were randomized across two diet approaches: a modified version of the MyPlate diet (usual care (UC)) and a modified Stoplight Diet (SLDm) supplemented with portion-controlled meals. Project staff met monthly with each participant to measure weight, 24-recalls of diet intake, self-tracking of foods and beverages, and physical activity during the preceding month. RESULTS: Of 126 enrollees, 70% completed the initial 6-month diet phase and 60% of these completed a 6-month follow-up phase. Participants in the SLDm group reduced weight and BMI during the 6 month intervention, and maintained or lost more weight during the 6 month maintenance period. Alternately, the UC diet resulted in a reduction in weight and BMI only at 6 months. BMI from baseline was significantly more improved for SLDm than UC and, among those who lost weight, the SLDm group lost more weight at 6 and 12 months. CONCLUSIONS: These results demonstrate that interventions with proper design and accommodations can overcome the barriers to weight loss unique to individuals with mobility impairments with low income. Additionally, the results suggest that using portion control may be more effective than teaching portion sizes.

Research contributions and implications.

Distinguishing and characterizing the terms "chronic conditions" and "disability" is important to the quality of public health research. Research has documented that people with disabilities experience higher prevalences of chronic conditions than the general population; however, these differences are rarely attributable to the pre-existing disability, and instead likely stem from preventable environmental factors. In this paper we describe contributions from the research as well as the need for a paradigm shift to effectively address the unique public health needs of people with disabilities. In addition, we describe evidence of support for such a paradigm shift. We intend for this paper to invite discussion in the field about methods to elicit the changes necessary in public health research for improved policy and practice that better address the public health needs of people with disabilities.

Using population-based data to examine preventive services by disability type among dually eligible (Medicare/Medicaid) adults.

BACKGROUND: Individuals dually eligible for Medicaid and Medicare constitute a small percentage of these program's populations but account for a disproportionately large percent of their total costs. While much work has examined high expenditures, little is known about their health and details of their health care utilization. OBJECTIVE/HYPOTHESIS: Utilize an important public health surveillance tool to better understand preventive service use among the dual eligible population. METHODS: This study involved descriptive and regression analyses of dual eligibles in the Medical Expenditure Panel Survey data from pooled alternate years 2000-2008. We classified the sample into 4 mutually exclusive groups: cognitive limitations, physical disabilities, double diagnosis (cognitive limitations and physical disability), or neither cognitive limitations nor physical disability. RESULTS: For most groups, age was significantly associated with preventive services, though direction varies. Older age was linked to greater receipt of flu shots while younger age was associated with greater receipt of Pap tests, mammograms and dental services. Black women in all groups (except cognitive limitations) had an increased likelihood of receiving a Pap test and a mammogram. CONCLUSIONS: A subset of dual eligibles drives the majority of expenditures. People with physical disabilities, regardless of whether they also have a cognitive limitation, are among the highest costing and sickest of our non-institutionalized dual eligible population. Efforts to understand and address the challenges faced by women with physical disabilities in accessing Pap tests or mammograms may be helpful in improving the overall health status for this disability group, but also for all dual eligibles.

Learning your ABDs: variation in health care utilization across Kansas Medicaid disability groups.

BACKGROUND: State Medicaid programs provide critical health care access for persons with disabilities and older adults. Aged, Blind and Disabled (ABD) programs consist of important disability subgroups that Medicaid programs are not able to readily distinguish. OBJECTIVE/HYPOTHESIS: The purpose of this project was to create an algorithm based principally on eligibility and claims data to distinguish disability subgroups and characterize differences in demographic characteristics, disease burden, and health care expenditures. METHODS: We created an algorithm to distinguish Kansas Medicaid enrollees as adults with intellectual or developmental delays (IDD), physical disabilities (PD), severe mental illness (SMI), and older age. RESULTS: For fiscal year 2009, our algorithm separated 101,464 ABD enrollees into the following disability subgroups: persons with IDD (19.6%), persons with PD (21.0%), older adults (19.7%), persons with SMI (32.8%), and persons not otherwise classified (6.9%). The disease burden present in the IDD, PD, and SMI subgroups was higher than for older adults. Home- and community-based services expenditures were common and highest for persons with IDD and PD. Older adults and persons with SMI had their highest expenditures for long-term care. Mean Medicaid expenditures were consistently higher for adults with IDD followed by adults with PD. CONCLUSIONS: There are substantial differences between disability subgroups in the Kansas Medicaid ABD population with respect to demographics, disease burden, and health care expenditures. Through this algorithm, state Medicaid programs have the opportunity to collaborate with the most closely aligned service providers reflecting needed services for each disability subgroup.

Quality of diabetes care for adults with physical disabilities in Kansas.

BACKGROUND: Similar to health disparities found among racial and ethnic minority groups, individuals with physical disabilities experience a greater risk for diabetes than those without disabilities. OBJECTIVE: The purpose of this works was to assess Kansas Medicaid data to determine the quality of diabetic care and the level to which individuals with physical disabilities' prevention and diabetes management needs are being met. METHODS: We selected a continuously eligible cohort of adults (ages 18 and older) with physical disabilities who had diabetes and received medical benefits through Kansas Medicaid. We examined their quality of care measures (screening for HbA1c/glucose, cholesterol, and eye exams; and, primary care visits) in the succeeding year. Using unconditional logistic regression, we assessed the measures for quality of care as they related to demographic variables and comorbid hypertension. RESULTS: Thirty-nine percent of the 9,532 adults with physical disabilities had diabetes. They had the following testing rates: HbA1c, 82.7%; cholesterol, 51.5%; and eye examinations, 86.8%. Females, those with dual eligibility, and those with comorbid hypertension had higher rates for all types of screenings and primary care visits. Those living in MUAs had a higher screening rate for cholesterol. CONCLUSIONS: Adults with physical disabilities supported by Kansas Medicaid received diabetes quality indicator screenings have better diabetes quality of care rates for 3 out of 4 measures than nationally published figures for Medicaid. These findings point to a strong quality of care programs in Kansas for this population; however an imperative next step is to determine how effectively this population is managing their blood sugar levels day-to-day.

A systematic scoping review of measures of participation in disability and rehabilitation research: a preliminary report of findings.

PURPOSE/OBJECTIVE: The concept of participation is emerging as a gold-standard of outcome measurement in disability and rehabilitation. We aimed to assess the status of methods to measure this new concept. METHOD/DESIGN: We conducted a scoping review and a content analysis to assess the literature on participation. RESULTS: We identified 586 articles addressing participation. Seventy-two articles passed all exclusion criteria. Twenty-four articles cited the International Classification of Function as their conceptual foundation. Most studies included individuals with a broad range of impairments (cross disability). Most instruments relied on self-report in a cross-sectional design. We noted three levels of measurement (static, interactional, and dynamic). Few studies reported collecting data on the environment along with participation. Subjective aspects of participation emerged as an important consideration but few articles reported measuring it. CONCLUSIONS: The concept of participation represents more than a "shift from negative to more positive language." It represents a transformational concept that requires new, dynamic measures collected in context.

Diabetes among adults with cognitive limitations compared to individuals with no cognitive disabilities.

Using a retrospective analysis of data from the 2006 Medical Expenditures Panel Survey (MEPS), we assessed the health status of working-age adults with cognitive limitations in comparison to adults with no disability (unweighted N  =  27,116; weighted N  =  240,343,457). Adults with cognitive limitations had a significantly higher prevalence of diabetes than did adults with no disability (19.4% vs. 3.8%, respectively) and a significantly higher prevalence of six other major chronic conditions. In addition, individuals with cognitive limitations and diabetes were significantly more likely to have multiple (four or more) chronic illnesses. The health disparities we found in this study demonstrate the need to improve disease prevention and education efforts for individuals with cognitive limitations and their health care providers.
