The complex web of health: relationships among chronic conditions, disability, and health services

Using the Functional Comorbidity Index with administrative workers' compensation data: Utility, validity, and caveats

BACKGROUND

Chronic health conditions impact worker outcomes but are challenging to measure using administrative workers' compensation (WC) data. The Functional Comorbidity Index (FCI) was developed to predict functional outcomes in community-based adult populations, but has not been validated for WC settings. We assessed a WC-based FCI (additive index of 18 conditions) for identifying chronic conditions and predicting work outcomes.

METHODS

WC data were linked to a prospective survey in Ohio (N = 512) and Washington (N = 2,839). Workers were interviewed 6 weeks and 6 months after work-related injury. Observed prevalence and concordance were calculated; survey data provided the reference standard for WC data. Predictive validity and utility for control of confounding were assessed using 6-month work-related outcomes.

RESULTS

The WC-based FCI had high specificity but low sensitivity and was weakly associated with work-related outcomes. The survey-based FCI suggested more comorbidity in the Ohio sample (Ohio mean = 1.38; Washington mean = 1.14), whereas the WC-based FCI suggested more comorbidity in the Washington sample (Ohio mean = 0.10; Washington mean = 0.33). In the confounding assessment, adding the survey-based FCI to the base model moved the state effect estimates slightly toward null (<1% change). However, substituting the WC-based FCI moved the estimate away from null (8.95% change).

CONCLUSIONS

The WC-based FCI may be useful for identifying specific subsets of workers with chronic conditions, but less useful for chronic condition prevalence. Using the WC-based FCI cross-state appeared to introduce substantial confounding. We strongly advise caution-including state-specific analyses with a reliable reference standard-before using a WC-based FCI in studies involving multiple states.

'Being disabled' as an exclusion criterion for clinical trials: a scoping review

BACKGROUND

People with disabilities (PWDs) are often excluded from biomedical research, but comprehensive data regarding their participation in clinical trials are not available. The objective of this study was to assess the rates of exclusion of PWDs from recent medical scientific research.

METHODS

The protocol of the study was designed according to PRISMA-ScR (PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) extension for Scoping Reviews) guidelines. All completed interventional clinical trials registered on ClinicalTrials.gov between 2010 and 2020 regarding the 10 leading causes of global disability-adjusted life-years according to the Global Burden of Disease Study were analysed. An exclusion criterion from the study was considered explicit if it could be associated with one of the following seven categories: disability, physical impairment, cognitive impairment, behavioural or psychiatric disorders, language and communication impairment, sensory impairment. Comorbidities not more clearly defined and researcher discretion regarding exclusion of study participants were considered to be 'implicit exclusion criteria'. We assessed the appropriateness of explicit exclusion criteria in relation to the primary objectives of the trials and labelled them as 'absolute', 'relative' or 'questionable'.

RESULTS

The total number of trials analysed was 2710; 170 were paediatric trials (6.3%), 2374 were adult trials (87.6%) and 166 were trials including subjects of all ages (6.1%). Explicit exclusion criteria were found in 958 trials (35.3%). The disability category most frequently excluded was behavioural or psychiatric disorders, present in 588 trials (61.4%). In only 3% and 1% of the trials, the exclusion criteria were considered either 'absolute' or 'questionable', while in 96% the exclusion criteria were judged as 'relative'. Implicit exclusion criteria were present in 1205 trials (44.5%).

CONCLUSIONS

This study highlights the high rate of exclusion of PWDs from biomedical research and the widespread use of ill-defined exclusion criteria in clinical trials. It underscores the importance of more inclusive study designs so that PWDs can become active participants in research.

The Impact of Cybervictimization on the Self-Management of Chronic Conditions: Lived Experiences

BACKGROUND

Cybervictimization of people with long-term conditions is a disturbing phenomenon with a documented impact on health and well-being. These experiences are primarily examined using quantitative methods, focusing on children and young people. However, research centered on the cybervictimization of adults with chronic conditions is scarce, with limited qualitative input from the victims as experts in their own experiences.

OBJECTIVE

This study aims to understand the impact of cybervictimization on the self-management of long-term conditions among adults with chronic conditions and disabilities in the United Kingdom.

METHODS

This paper reports the findings from the qualitative phase of a phenomenologically informed mixed methods study. The biographical disruption concept was used to conceptualize the study. In-depth semistructured interviews were conducted with 13 participants with chronic conditions who experienced cybervictimization. A codebook was developed, and a zigzag approach to thematic analysis was used to define and refine themes. Ethical considerations and risk assessment were ongoing during the research process because of the sensitivity of the topic and cases of harassment.

RESULTS

Cybervictimization has direct and indirect impacts on the self-management of chronic conditions. This impact was verified across 6 overarching themes that emerged from this study. First, biomedical events included overall health deterioration because of existing conditions, new diagnoses, and subjective physical complaints. Second, the impact on mental health was perceived through psychological consequences and psychiatric disorders that developed after or during this traumatic experience. Third, the multilevel impact theme focused on disrupting the strategies for coping with health conditions and involved unplanned changes to victims' health management priorities. Fourth, the impact of complexity reflected the perceived uniqueness in each case, intersectionality, struggle to obtain formal support, and subsequent health complications. Fifth, social network involvement comprised the effects of social isolation, victim blaming, and deception. Finally, the disability discrimination theme focused on prejudice, issues on inclusion, and hostility in society, with subsequent effects on well-being.

CONCLUSIONS

People with long-term conditions experienced different forms of cybervictimization, all disruptive with various effects on health. Disability discrimination was a prominent finding to be further investigated. This paper reports the impact as themes to guide further research and practice, with the recognition that long-term conditions and impairments are not a homogeneous group. Despite the devastating consequences, there are positive points that strengthen potential interventions. Awareness-raising campaigns, training of support channels, and multidisciplinary research are recommended to tackle this issue and initiate change.

Potentially Preventable Hospitalization Among Adults with Hearing, Vision, and Dual Sensory Loss: A Case and Control Study

Objective

To evaluate the risk of potentially preventable hospitalizations (PPHs) among adults with sensory loss. We hypothesized a greater PPH risk among people with a sensory loss (hearing, vision, and dual) compared with controls.

Patients and Methods

Using 2007-2016 Medicare fee-for-service claims, this retrospective, case-control study examined the risk of PPH among adults aged 65 years and older with hearing, vision, and dual sensory loss compared with their corresponding counterparts without sensory loss (between June 1, 2022, and February 1, 2023). We ran 3 step-in regression models for the 3 case and control cohorts examining PPH risk. Our generalized linear regression models controlled for age, sex, race, Elixhauser comorbidity count, rurality, neighborhood characteristics, and the number of primary care physicians and hospitals at the county level.

Results

People with vision (adjusted odds ratio [aOR], 1.21; 95% CI, 0.84-0.87) and dual sensory loss (aOR, 1.26; 95% CI, 1.14-1.40) showed a higher PPH risks than their corresponding controls. For people with hearing loss, our unadjusted models showed a higher PPH risk (OR, 1.40; 95% CI, 1.38-1.43) but after adjustment, hearing loss showed a protective association against PPH risk (OR, 0.85; 95% CI, 0.84-0.87). Moreover, in all models, annual wellness visits reduced the PPH risk by about half (eg, aOR, 0.54; 95% CI, 0.52-0.55), whereas living in disadvantaged neighborhood increased the PPH risk (eg, aOR, 1.13; 95% CI, 1.10-1.15) for cases and controls.

Conclusion

People with vision and dual sensory loss were at greater PPH risk. This study has important health policy implications in reducing PPH and is indicative of a need for more incentivized and systematic approaches to facilitating the use of preventive care, particularly among older adults living in a disadvantaged neighborhood.

Parental Stress in Raising a Child with Developmental Disabilities in a Rural Community in South Africa

Although acceptable levels of parental stress are experienced by all parents who raise children, this stress is substantially higher among parents who raise children with developmental disabilities. Sociodemographic determinants further exacerbate parental stress among parents in rural communities, which are disadvantaged in many ways. This study aimed to quantify parental stress among mothers and female caregivers of children with developmental disorders and investigate factors associated with such stress in rural Kwa-Zulu Natal, South Africa. A cross-sectional quantitative survey was used, in which the Parenting Stress Index-Short Form (PSI-SF) and a sociodemographic questionnaire was administered to mothers and caregivers who were raising children aged 1 to 12 years old who were living with developmental disabilities. The PSI-SF scores were used, where a total score of ≤84 percentile was categorised as normal/no parenting stress, 85-89 percentile was categorised as high parental stress, and scores of ≥90 were classified as clinically significant. The sample of 335 participants consisted of 270 (80.6%) mothers and 65 (19.4%) caregivers. Their ages ranged from 19 to 65 years, with a mean of 33.9 (±7.8) years. The children were mostly diagnosed with delayed developmental milestones, communication difficulties, epilepsy, cerebral palsy, autism, ADHD, cognitive impairment, sensory impairments, and learning difficulties. The majority (52.2%) of the participants reported very high-clinically significant stress levels (≥85%ile). The four factors that independently and significantly predicted high parental stress were the advanced age of mothers and caregivers (p = 0.002, OR 2.3, 95% CI 1.34-3.95), caring for a child with multiple diagnoses (p = 0.013, OR 2.0, 95% CI 1.16-3.50), non-school enrolment of the child (p = 0.017, OR 1.9, 95% CI 1.13-3.46), and frequent hospital visits (p = 0.025, OR 1.9, 95% CI 1.09-3.44). At the subscale level, child non-enrolment in a school was found to independently predict parent distress (PD) and parent-child dysfunctional interaction (P-CDI). Frequent hospital visits were statistically and significantly associated with the difficult child (DC) and P-CDI subscales. The study established high parental stress in mothers and caregivers raising children with developmental disabilities. Lack of access to school was an independent factor that consistently increased parental stress. There is a need for support and directed intervention programs aimed at supporting mothers and caregivers of children with developmental disabilities, which will enhance their parenting abilities.

Americans Aging With Disabilities Are More Likely to Have Multiple Chronic Conditions

Using data from the 2010 to 2017 National Health Interview survey, bivariate and multivariate regression analyses were utilized to estimate the percentage and odds of having multiple chronic conditions (two or more, three or more) among U.S. adults ages 65 and over with and without disabilities, controlling for sociodemographic factors and presence of psychological distress. Older adults with and without disabilities in the United States most frequently reported having hypertension, arthritis, and diabetes. Regression results indicate that older adults with disabilities are significantly more likely to experience two or more and three or more chronic conditions than older adults without disabilities, controlling for sociodemographic factors and health behaviors. These findings highlight a need for improvement in coordinated care that considers both disability and multiple chronic conditions in the management of patient health to support well-being in aging.

What Can We Learn From a Human-Rights Based Approach to Disability for Public and Patient Involvement in Research?

Public and Patient Involvement can align both the research process and its outcomes with the values, needs and expectations of society. By fostering the design of inclusive, engaged, and sustainable practices, research and research integrity can be improved. Devolving power to involve patients and relevant publics in deliberative decision making can produce better research outcomes. Disabled people are often categorized as “Hard to Reach.” There is a varied and complex ecosystem of societal challenges of living with a disability that reinforce this. However, if researchers are to meet their obligations under the UN Convention on the Rights of Persons with Disabilities, disabled people should be included in public and patient involvement for all research in which they have a stake. In this article we argue that a better understanding of rights-based approaches and the social model of disability within the wider research community can help to remove barriers to research involvement for disabled persons. We focus on articles 3, 4, and 9 of the Convention and discuss how the principles of participation, accessibility, and equality of opportunity can be applied to research involvement, and how their adoption can facilitate truly meaningful PPI in disability research.

Risk Adjustment in Home and Community Based Services Outcome Measurement

The purpose of this study was to review and evaluate existing research that used risk adjusters in disability research. Risk adjustment controls for individual characteristics of persons when examining outcomes. We have conducted a systematic review and an evaluation of existing studies that included risk adjusters for outcomes of people with disabilities receiving services (home or community based). The process included coding each study according to the type(s) of risk adjusters employed and their relation to the specific population and outcomes within a framework. Panels were utilized to prioritize the risk adjusters. Findings indicate that four risk adjusters can be tentatively recommended as potential candidate risk adjusters: chronic conditions, functional disability, mental health status, and cognitive functioning. Holistic Health and Functioning far outweighed other outcomes studied to date. Further, there is a need for testing recommended risk adjusters across multiple outcomes and different populations of people with disabilities.

Everyday Lives of Middle-Aged Persons with Multimorbidity: A Mixed Methods Systematic Review

The healthcare burden of patients with multimorbidity may negatively affect their family lives, leisure time and professional activities. This mixed methods systematic review synthesizes studies to assess how multimorbidity affects the everyday lives of middle-aged persons, and identifies skills and resources that may help them overcome that burden. Two independent reviewers screened title/abstracts/full texts in seven databases, extracted data and used the Mixed Methods Appraisal Tool (MMAT) to assess risk of bias (RoB). We synthesized findings from 44 studies (49,519 patients) narratively and, where possible, quantitatively. Over half the studies provided insufficient information to assess representativeness or response bias. Two studies assessed global functioning, 15 examined physical functioning, 18 psychosocial functioning and 28 work functioning. Nineteen studies explored skills and resources that help people cope with multimorbidity. Middle-aged persons with multimorbidity have greater impairment in global, physical and psychosocial functioning, as well as lower employment rates and work productivity, than those without. Certain skills and resources help them cope with their everyday lives. To provide holistic and dynamic health care plans that meet the needs of middle-aged persons, health professionals need greater understanding of the experience of coping with multimorbidity and the associated healthcare burden.

Unmet health care needs and inequality: A cross-country comparison of the situation of people with spinal cord injury

Objective

To estimate and compare unmet health care needs of persons with spinal cord injury (SCI) across countries, the causes of these shortfalls, and the role of income.

Data Sources

We analyzed cross‐sectional data of 20 countries from the International Spinal Cord Injury (InSCI) survey, a compendium of comparable data on the living situation of persons with SCI. Data included information on high‐, middle‐, and low‐income countries. The survey comprises information on 12,095 participants.

Study Design

We used logit regressions to estimate the probability of unmet health care needs of persons with SCI and its causes. We adjusted the results by the individuals' characteristics and countries' fixed effects. We disaggregated the results by income decile of individuals in each country.

Data Collection/Extraction Methods

The inclusion criteria for the InSCI survey were adults aged 18 years and older with SCI living in the community, who were able to respond to the survey and who provided informed consent.

Principal Findings

Unmet health care needs are significant for people with long‐term conditions like SCI, where people in low‐income groups tend to be more affected. Among the barriers to meeting health care needs, the foremost is health care cost (in 11 of the 20 countries), followed by transportation and service availability. Persons with SCI in Morocco reported the highest probability of unmet health care needs in the sample, 0.54 (CI: 047–0.59), followed well behind by South Africa, 0.27 (CI: 0.20–0.33), and Brazil, 0.26 (CI: 0.20–0.33). In contrast, persons with SCI in Spain, 0.06 (CI: 0.04–0.08), reported the lowest probability of unmet health care needs, closely followed by Norway, 0.07 (CI: 0.05–0.09), Thailand, 0.08 (CI: 0.05–0.11), France, 0.08 (CI: 0.06–0.11), and Switzerland, 0.09 (CI: 0.07–0.10).

Conclusions

SCI is a long‐term, irreversible health condition characterized by physical impairment and a series of chronic illness. This makes SCI a high‐need, high‐cost group that faces significant unmet health care needs, which are mainly explained by the costs of health services, transportation, and services availability. This situation is prevalent in low‐, middle‐, and high‐income countries, where persons in lower income groups are disproportionately affected. To improve the situation, a combination of measures from the health and social systems are required.

Characterization of People with Functional Limitations from ICF Components Using the Longitudinal Social Protection Survey (ELPS) of Uruguay

Characterising people with disabilities at the population level using the ICF approach is a challenge, as it implies that researchers are able to identify variables that can account for the components that make up the multidimensional definition of disability. The purpose of this study is to generate updated information on disability in Uruguay, as there has been no in-depth analysis of how this population lives, how they access the services and benefits that affect their quality of life, and what the significant differences are between those who make up this population. A quantitative analysis was applied to the target population, consisting of participants in the Longitudinal Survey of Social Protection (2016) who reported at least one limitation in performing ADLs and who were in the age range of 18–64 years. Significant differences were found between the different groups in terms of their reported limitations in relation to obtaining necessary services due to their health condition, dropping out of education before completing the compulsory level, low labour market insertion, feelings of loneliness, and low participation. More research needs to be done as it is clear that people with disabilities do not have access to the support they need, which leads to even greater exclusion.

The Role of Earlier Receipt of a Lower Limb Prosthesis on Emergency Department Utilization

Introduction

Adverse events after a lower limb amputation (LLA) can negatively affect the rehabilitation process and may lead to emergency department (ED) visits. Earlier receipt of a prosthesis, as compared to delayed or not receiving a prosthesis, may decrease or moderate the risk of increased ED utilization. In addition, adverse events (ie, fall‐related injury [FRI]) may be associated with increased health care utilization as measured by ED use. The implication of the timing of prosthesis provision after amputation and reduced ED use is not well established. Obtaining data about ED utilization early post‐LLA could assist the rehabilitation team in ensuring timely and appropriate access to improve outcomes.

Objective

To determine the role that timing of prosthesis receipt has in ED utilization and the association of fall/FRI with health care utilization.

Design

Retrospective observational cohort using commercial claims data. A logistic regression model was used to assess factors that influence ED utilization post‐LLA.

Setting

Watson/Truven administrative database 2014 to 2016.

Participants

The study sample consisted of 510 adults age 18 to 64 years with continuous enrollment for 3 years.

Interventions

Independent variables included age, sex, diabetes status, amputation level, fall diagnosis, and prosthesis receipt. Fall was defined as presence of a diagnosis code in any outpatient procedure after the amputation date.

Main Outcome Measure

ED use after amputation was defined as the presence of procedure codes that billed for ED services (99281 to 99285).

Results

Individuals who receive a prosthesis early, within 0 to 3 months, post‐LLA were 48% (odds ratio [OR] 0.52, 95% confidence interval [CI] 0.28 to 0.97) less likely to use the ED compared to those who did not receive a prosthesis. Individuals who experienced a fall/FRI had 2.8 (OR 2.86, 95% CI 1.23 to 6.66) times the odds of ED utilization.

Conclusion

Receipt of a prosthesis reduces the risk of ED use. The current study underscores the value of prostheses during the rehabilitation process after LLA.

Healthcare utilization of individuals with substance use disorders following Affordable Care Act implementation in a California healthcare system

BACKGROUND

Practitioners expected the Affordable Care Act (ACA) to increase availability of health services and access to treatment for Americans with substance use disorders (SUDs). Yet research has not examined the associations among ACA enrollment mechanisms, deductibles, and the use of SUD treatment and other healthcare services. Understanding these relationships can inform future healthcare policy.

METHODS

We conducted a longitudinal analysis of patients with SUDs newly enrolled in the Kaiser Permanente Northern California health system in 2014 (N = 6957). Analyses examined the likelihood of service utilization (primary care, specialty SUD treatment, psychiatry, inpatient, and emergency department [ED]) over three years after SUD diagnosis, and associations with enrollment mechanisms (ACA Exchange vs. other), deductibles (none, $1-$999 [low] and ≥$1000 [high]), membership duration, psychiatric comorbidity, and demographic characteristics. We also evaluated whether the enrollment mechanism moderated the associations between deductible limits and utilization likelihood.

RESULTS

Service utilization was highest in the 6 months after SUD diagnosis, decreased in the following 6 months, and remained stable in years 2-3. Relative to patients with no deductible, those with a high deductible had lower odds of using all health services except SUD treatment; associations with primary care and psychiatry were strongly negative among Exchange enrollees. Among non-Exchange enrollees, patients with deductibles were more likely than those without deductibles to receive SUD treatment. Exchange enrollment compared to other mechanisms was associated with less ED use. Psychiatric comorbidity was associated with greater use of all services. Nonwhite patients were less likely to initiate SUD and psychiatry treatment.

CONCLUSIONS

Higher deductibles generally were associated with use of fewer health services, especially in combination with enrollment through the Exchange. The role of insurance factors, psychiatric comorbidity and race/ethnicity in health services for people with SUDs are important to consider as health policy evolves.

Longitudinal associations of multimorbidity, disability and out-of-pocket health expenditures in households with older adults in Mexico: The study on global AGEing and adult health (SAGE)

BACKGROUND

Empirical evidence suggests that multimorbidity and disability are each significantly associated with out-of-pocket (OOP) health expenditures; however few efforts have been made to explore their joint association with OOP health expenditures.

OBJECTIVES

To estimate the association of multimorbidity and disability with OOP health expenditures in households with older adults in Mexico, as well as the potential interaction effects of multimorbidity and disability on OOP health expenditures.

METHODS

Longitudinal study based on data collected as part of the Study on global AGEing and adult health Wave 1 (2009) and Wave 2 (2014), a nationally representative study in Mexico with a sample of older adults aged 50 and older. The dependent variable was OOP health expenditures, and main exposure variables were multimorbidity and disability. Two-Part regression models were used to analyze the relation between multimorbidity, disability and OOP health expenditures.

RESULTS

Multimorbidity was associated with the probability of incurring OOP health expenditures (OR = 1.28, CI_95% 1.11-1.48), and also the tertiles of disability (2nd tertile: OR = 1.45, CI_95% 1.23-1.70; 3rd tertile: OR = 2.19, CI_95% 1.81-2.66). The presence of multimorbidity was associated with an increase of 13% in average OOP health costs (β = 0.13, CI_95% 0.01-0.25), and 16% for the 3rd tertile of disability (β = 0.16, CI_95% 0.01-0.31). We did not find significant interaction effects of multimorbidity and disability.

CONCLUSIONS

Multimorbidity and disability appear to be important determinants of OOP health expenditures. The economic implications for the households and the health system should be highlighted, particularly in low- and middle-income countries because of the rapid growth of their aging populations.

Challenges in Accessing Health Care for People with Disability in the South Asian Context: A Review

South Asia is a unique geopolitical region covering 3.4% of the world’s surface area and supporting 25% of the world’s population (1.75 billion). Available evidence from South Asia shows variable estimates of the magnitude of disability. The projected magnitude depends on whether an impairment focus is highlighted (approximately 1.6–2.1%) or functionality is given precedence (3.6–15.6%). People with disability (PWD) face significant challenges to accessing health care in the region. Studies show that adults with disability reported a four times higher incidence of a serious health problem in a year’s recall period. Evidence shows a significantly higher rate (17.8%) of hospitalization among PWD compared to others (5%). Chronic conditions like diabetes were also significantly higher. Women with disability had significantly more concerns on reproductive health issues. Studies from the South Asia region reveal that not only did PWD have a higher load of adverse health outcomes but they also faced significantly more barriers in accessing health services.

The risk, burden, and management of non-communicable diseases in cerebral palsy: a scoping review

AIM

To examine the risk, burden, and management of non-communicable diseases (NCDs) among people with cerebral palsy (CP).

METHOD

Databases (Ovid MEDLINE, Embase Ovid, CINAHL Plus) were systematically searched up to August 2017. Data on the prevalence of risk factors for, and the burden and management of, cardiovascular diseases, diabetes, cancers, and respiratory diseases were extracted.

RESULTS

Thirty-six studies that examined the prevalence of risk factors among people with CP were identified. There was inconsistent evidence that people with CP had higher prevalence of metabolic risk factors such as hypertension, hyperlipidaemia, and obesity, but strong evidence that they participated in low levels of physical activity, compared with people without CP. Seven studies reported on the burden of NCDs. Adults with CP had a higher risk of NCDs, including stroke, chronic obstructive pulmonary disease, and other heart conditions, and death due to NCDs, including cancers, chronic obstructive pulmonary disease, stroke, and ischaemic heart disease, compared with the general population. Only one study reported on the management of NCD, specifically the uptake of breast cancer screening among females.

INTERPRETATION

The burden of NCDs is higher among adults with CP compared with the general population. Further research is required to determine the prevalence of metabolic risk factors and management of NCDs among people with CP.

WHAT THIS PAPER ADDS

Adults with cerebral palsy (CP) have an increased risk of non-communicable diseases (NCDs) and increased risk of death because of NCDs. Evidence is inconsistent about the elevated prevalence of metabolic risk factors for NCDs. Evidence is consistent that people with CP participate in reduced physical activity. Only one study reported on management of NCD among people with CP. Available evidence suggests people with CP are less likely to receive preventive medicine.

Multimorbidity and Health Care Service Utilization in the Australian Workforce: Findings From the National Health Survey

OBJECTIVES

The aim of this study was to understand the patterns of health care service utilization in employees with multimorbidity.

METHODS

Data were obtained from the 2011 to 2012 cross-sectional Australian National Health Survey. Past-month health care service utilization was collected for each chronic condition from a pre-specified list. Descriptive, logistic, and Poisson regression analyses were used. The data were weighted to produce nationally representative estimates.

RESULTS

Multimorbid employees with arthritis had higher adjusted arthritis-specific general practitioner (GP) visit rates [rate ratio (RR) = 1.7, 95% confidence interval (95% CI) = 1.1 to 2.2, P < 0.001] than employees with arthritis alone. Similarly, multimorbid employees with cardiovascular disease (CVD) had higher adjusted CVD-specific specialist visit rates (RR = 1.6, 95% CI = 1.1 to 2.5, P < 0.05) and 2.5 times (95% CI = 1.5 to 4.0, P < 0.001) more CVD-specific other health professional visits than employees with CVD alone.

CONCLUSIONS

Given the increasing number of employees managing work and chronic illnesses, these findings have implications for health services and employers.

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.

Perspectives on "Disease" and "Disability" in Child Health: The Case of Childhood Neurodisability

Chronic health conditions are often associated with what is termed disability. Traditional thinking has focused on diagnosis and treatment of chronic diseases and disorders, with less attention to people's functional abilities and their contextual determinants. Understanding all of these factors is integral to addressing the predicaments and needs of persons with chronic conditions. However, these complementary yet distinct "worldviews" reflected in what we call disease and disability perspectives often remain, at best, only vaguely articulated. In this paper, we explore and expand on these perspectives in light of conceptual advances, specifically the framework of the World Health Organization's International Classification of Functioning, Disability and Health, and their epistemic underpinnings with reference to Wilhelm Windelband's notions of nomothetic and idiographic types of knowledge. Our primary focus is the children with neurodisability - life-long conditions that onset early in life and have functional consequences that impact developmental trajectories. We critically review and analyze conceptual material, along with clinical and research evidence relevant to the experiential and clinical realities of this population, to demonstrate the limitations of a biomedically based diagnostic-therapeutic paradigm at the expense of a developmental and disability-oriented perspective. Our main aim in this paper is to argue for an explicit recognition of both disease and disability perspectives, and a more balanced and appropriate deployment of these concepts across the continuum of clinical services, research, policy-making and professional and public education in relation to children with neurodisability; we also provide concrete recommendations to advance this progressive strategy. The relevance of these aims and strategies, however, extends beyond this particular population.

Conducting Accessible Research: Including People With Disabilities in Public Health, Epidemiological, and Outcomes Studies

People with disabilities are largely absent from mainstream health research. Exclusion of people with disabilities may be explicit, attributable to poorly justified exclusion criteria, or implicit, attributable to inaccessible study documents, interventions, or research measures. Meanwhile, people with disabilities experience poorer health, greater incidence of chronic conditions, and higher health care expenditure than people without disabilities. We outline our approach to "accessible research design"-research accessible to and inclusive of people with disabilities. We describe a model that includes 3 tiers: universal design, accommodations, and modifications. Through our work on several large-scale research studies, we provide pragmatic examples of accessible research design. Making efforts to include people with disabilities in public health, epidemiological, and outcomes studies will enhance the interpretability of findings for a significant patient population.

Disability stage and receipt of recommended care among elderly medicare beneficiaries

BACKGROUND

Receipt of recommended care among older adults is generally low. Findings regarding service use among persons with disabilities supports the notion of disparities but provides inconsistent evidence of underuse of recommended care.

OBJECTIVE

To examine the extent to which receipt of recommended care among older Medicare beneficiaries varies by disability status, using a newly developed staging method to classify individuals according to disability.

METHODS

In a cohort study, we included community-dwelling Medicare beneficiaries aged 65 and older who participated in the Medicare Current Beneficiary Survey between 2001 and 2008. Logistic regression modeling assessed the association of receiving recommended care on 38 indicators across different activity limitation stages.

RESULTS

Nearly one out of every three elderly Medicare beneficiaries did not receive overall recommended care. Adjusted odds ratios (ORs) revealed a decrease in use of recommended care with increasing activity limitation stage. For instance, ORs (95% CIs) across mild, moderate, severe and complete limitation stages (stages I-IV) compared to no limitation (stage 0) in ADLs were 0.99 (0.94-1.05), 0.89 (0.83-0.95), 0.81 (0.75-0.89) and 0.56 (0.46-0.68). Disparities in receipt of recommended care by disability stage were most marked for care related to post-hospitalization follow-up and, to a lesser degree, care of chronic conditions and preventive care.

CONCLUSIONS

Elderly beneficiaries at higher activity limitation stages experienced substantial disparities in receipt of recommended care. Tailored interventions may be needed to reduce disparities in receipt of recommended medical care in this population.

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.

Comparison of 2 Disability Measures, Behavioral Risk Factor Surveillance System, 2013

Introduction

Beginning in 2013, in addition to the 2-item disability question set asked since 2001, Behavioral Risk Factor Surveillance System (BRFSS) began using 5 of the 6 items from the US Department of Health and Human Services–recommended disability question set. We assess and compare disability prevalence using the 2-question and 5-question sets and describe characteristics of respondents who identified as having a disability using each question set.

Methods

We used data from the 2013 BRFSS to estimate the prevalence of disability for each question set and the 5 specific types of disability. Among respondents identified by each disability question set, we calculated the prevalence of selected demographic characteristics, health conditions, health behaviors, and health status.

Results

With the 2-question set, 21.6% of adults had a disability and with the 5-question set, 22.7% of adults had disability. A total of 51.2% of adults who identified as having a disability with either the 2-question or 5-question set reported having disabilities with both sets. Adults with different disability types differed by demographic and health characteristics.

Conclusion

The inclusion of the 5 new disability questions in BRFSS provides a level of detail that can help develop targeted interventions and programs and can guide the adaptation of existing health promotion programs to be more inclusive of adults who experience specific types of disabilities.

Patients living with disabilities: The need for high-quality primary care

OBJECTIVE

To compare the potential risk factors for lower-quality primary care, the potential markers of unmet needs in primary care, and the willingness to participate in future research among primary care patients with versus without physical disabilities.

DESIGN

A waiting room survey using a convenience sample.

SETTING

A family health team (FHT) in Kitchener-Waterloo, Ont, with a designated Mobility Clinic.

PARTICIPANTS

A total of 40 patients seen at the FHT Mobility Clinic and 80 patients from the general patient population of the same FHT.

MAIN OUTCOME MEASURES

Socioeconomic status and social capital, number of self-reported emergency department visits and hospitalizations in the preceding year, and willingness of the patients in the 2 groups to participate in future research studies.

RESULTS

Patients from the Mobility Clinic were more than twice as likely to be receiving benefits or social assistance (75.0% vs 32.1%, P < .001), were twice as likely to report an annual household income of less than $40000 (58.6% vs 29.2%, P = .006), and were more likely to report their health status to be fair or poor (42.5% vs 16.2%, P = .002). Half of Mobility Clinic patients had visited the emergency department at least once in the preceding year, compared with 29.7% in the general patient population (P = .027). When asked if they would be willing to provide their health card number in the future so that it could be linked to health care data for research, 82.5% of Mobility Clinic patients agreed versus 55.0% of those in the general patient population (P = .004).

CONCLUSION

In this study, patients with disabilities were at a social disadvantage compared with their peers without disabilities and were more likely to use the emergency department, suggesting that they had unmet health needs. Future research should continue to explore this patient population and to investigate if an interprofessional primary health care team approach focused on patients with disabilities can help to increase quality of care.

Impact of disability and chronic conditions on health

BACKGROUND

Today one in five Americans have a disability and nearly half of Americans experiences a chronic condition. Whether disability results from or is a risk factor for chronic conditions, the combined effects of disability and chronic conditions warrants further investigation.

OBJECTIVES

Examine the added impact of chronic conditions among those with and without disability on self-reported health status and behaviors.

METHODS

2009 Behavioral Risk Factor Surveillance System (BRFSS) data were analyzed to examine the association of disability with unhealthy behaviors and poor health stratified by number of self-reported chronic conditions (0, 1, or 2+). Linear and logistic regression models accounting for the complex survey weights were used.

RESULTS

Participants with disability were 6 times more likely to report fair/poor self-rated health, reported 9 more unhealthy days in a month and 6 more days in a month when poor health kept them from usual activities, were 4 times more likely to be dissatisfied with life, had greater odds of being a current smoker, and were less likely to be physically active. Presence of chronic conditions in addition to disability was associated, in a dose-response manner, with poor health status and unhealthy behaviors.

CONCLUSIONS

People living with both chronic diseases and disability are at substantially increased risks for poor health status and unhealthy behaviors, further affecting effective management of their chronic conditions. Multi-level interventions in primary care and in the community that address social and environmental barriers that hinder adults with disability from adopting more healthy lifestyles and improving health are needed.

Potentially Avoidable Hospitalizations among People at Different Activity of Daily Living Limitation Stages

OBJECTIVE

To determine whether higher activity of daily living (ADL) limitation stages are associated with increased risk of hospitalization, particularly for ambulatory care sensitive (ACS) conditions.

DATA SOURCE

Secondary data analysis, including 8,815 beneficiaries from 2005 to 2006 Medicare Current Beneficiary Survey (MCBS).

STUDY DESIGN

ADL limitation stages (0-IV) were determined at the end of 2005. Hospitalization rates were calculated for 2006 and age adjusted using direct standardization. Multivariate negative binomial regression, adjusting for baseline demographic and health characteristics, with the outcome hospitalization count was performed to estimate the adjusted rate ratio of ACS and non-ACS hospitalizations for beneficiaries with ADL stages > 0 compared to beneficiaries without limitations.

DATA COLLECTION

Baseline ADL stage and health conditions were assessed using 2005 MCBS data and count of hospitalization determined using 2006 MCBS data.

PRINCIPAL FINDINGS

Referenced to stage 0, the adjusted rate ratios (95 percent confidence interval) for stage I to stage IV ranged from 1.9 (1.4-2.5) to 4.1 (2.2-7.8) for ACS hospitalizations compared with from 1.6 (1.3-1.9) to 1.8 (1.4-2.5) for non-ACS hospitalizations.

CONCLUSIONS

Hospitalization rates for ACS conditions increased more dramatically with ADL limitation stage than did rates for non-ACS conditions. Adults with ADL limitations appear particularly vulnerable to potentially preventable hospitalizations for conditions typically manageable in ambulatory settings.

Determinants of Mental Health Care Utilization in a Suicide High-risk Group With Suicidal Ideation

Objectives:

The suicide rate in Korea is increasing every year, and is the highest among the Organization for Economic Cooperation and Development countries. Psychiatric patients in particular have a higher risk of suicide than other patients. This study was performed to evaluate determinants of mental health care utilization among individuals at high risk for suicide.

Methods:

Korea Health Panel data from 2009 to 2011 were used. Subjects were individuals at high risk of suicide who had suicidal ideation, a past history of psychiatric illness, or had utilized outpatient services for a psychiatric disorder associated with suicidal ideation within the past year. The chi-square test and hierarchical logistic regression were used to identify significant determinants of mental health care utilization.

Results:

The total number of subjects with complete data on the variables in our model was 989. Individuals suffering from three or more chronic diseases used mental health care more frequently. Mental health care utilization was higher in subjects who had middle or high levels of educational attainment, were receiving Medical Aid, or had a large family size.

Conclusions:

It is important to control risk factors in high-risk groups as part of suicide prevention strategies. The clinical approach, which includes community-based intervention, entails the management of reduction of suicidal risk. Our study identified demographic characteristics that have a significant impact on mental health care utilization and should be considered in the development of suicide prevention strategies. Further studies should examine the effect of mental health care utilization on reducing suicidal ideation.

Health-care access among adults with epilepsy: The U.S. National Health Interview Survey, 2010 and 2013

INTRODUCTION

Community-based and other epidemiologic studies within the United States have identified substantial disparities in health care among adults with epilepsy. However, few data analyses addressing their health-care access are representative of the entire United States. This study aimed to examine national survey data about adults with epilepsy and to identify barriers to their health care.

MATERIALS AND METHODS

We analyzed data from U.S. adults in the 2010 and the 2013 National Health Interview Surveys, multistage probability samples with supplemental questions on epilepsy. We defined active epilepsy as a history of physician-diagnosed epilepsy either currently under treatment or accompanied by seizures during the preceding year. We employed SAS-callable SUDAAN software to obtain weighted estimates of population proportions and rate ratios (RRs) adjusted for sex, age, and race/ethnicity.

RESULTS

Compared to adults reporting no history of epilepsy, adults reporting active epilepsy were significantly more likely to be insured under Medicaid (RR=3.58) and less likely to have private health insurance (RR=0.58). Adults with active epilepsy were also less likely to be employed (RR=0.53) and much more likely to report being disabled (RR=6.14). They experience greater barriers to health-care access including an inability to afford medication (RR=2.40), mental health care (RR=3.23), eyeglasses (RR=2.36), or dental care (RR=1.98) and are more likely to report transportation as a barrier to health care (RR=5.28).

CONCLUSIONS

These reported substantial disparities in, and barriers to, access to health care for adults with active epilepsy are amenable to intervention.

Development and Application of a Genetic Algorithm for Variable Optimization and Predictive Modeling of Five-Year Mortality Using Questionnaire Data

The problem of selecting important variables for predictive modeling of a specific outcome of interest using questionnaire data has rarely been addressed in clinical settings. In this study, we implemented a genetic algorithm (GA) technique to select optimal variables from questionnaire data for predicting a five-year mortality. We examined 123 questions (variables) answered by 5,444 individuals in the National Health and Nutrition Examination Survey. The GA iterations selected the top 24 variables, including questions related to stroke, emphysema, and general health problems requiring the use of special equipment, for use in predictive modeling by various parametric and nonparametric machine learning techniques. Using these top 24 variables, gradient boosting yielded the nominally highest performance (area under curve [AUC] = 0.7654), although there were other techniques with lower but not significantly different AUC. This study shows how GA in conjunction with various machine learning techniques could be used to examine questionnaire data to predict a binary outcome.

How professional identity shapes youth healthcare

PURPOSE

The primary care sector is experiencing considerable change. How change and uncertainty are accommodated by the professional identity of medicine has not been examined. The purpose of this paper is to address the youth healthcare as an exemplar as this field is often a source of uncertainty for general practitioners (GPs).

DESIGN/METHODOLOGY/APPROACH

Using heterogeneity sampling, 22 GPs participated in focus groups to explore perceptions of youth healthcare, factors that help and hinder it, and training needs. Analysis of the research material was guided by a theoretical model on professional identity.

FINDINGS

GPs described tensions that challenged their professional identity - the challenges of working with young people and their complex issues, the extent to which youth healthcare sits within the purview of general practice, and the scope of training required. These tensions appeared to destabilise professional identity. Some participants had customised their identity by enriching understandings of and approach to general practice. Participants also reported work customisation as a way of managing the complex demands of the general practice role. Deepened insight appeared to bolster perceived capacity to support a complex patient cohort. Research limitations/implications - Participants are not representative of the primary care sector - furthermore, the methodology limits the generalisability of the findings.

PRACTICAL IMPLICATIONS

To bolster youth health, mere clinician training is insufficient. Youth health requires explicit support from governments and training providers to be incorporated into the healthcare landscape.

ORIGINALITY/VALUE

This study extends current research on professional identity by examining youth healthcare within the changing context of primary care.

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.

Health care utilization by people with disabilities: A longitudinal analysis of the Korea Welfare Panel Study (KoWePS)

BACKGROUND

Health care is important for people with disabilities in terms of maintaining basic functional status and promoting health. However, empirical studies on health care utilization by this population in South Korea are rare.

OBJECTIVE

The purpose of this study was to examine the characteristics of people with disabilities and to evaluate the relationship between the presence and severity of disabilities and health care utilization.

METHODS

We analyzed the 2005-2011 Korea Welfare Panel Study data, and the final sample included 38,598 observations over seven years. Health care utilization was measured by health screening attendance, number of outpatient physician visits, and inpatient days. To examine the impact of disabilities on health care utilization, random-effects logistic regression and negative binomial regression models were adopted.

RESULTS

About 3.3% of the sample had physical disabilities, as defined by the Korean disability registration system. In the sample, the prevalence of chronic diseases and percentage of poor self-rated health were higher in people with disabilities than in people without disabilities. The results of the regression analyses showed that people with severe disabilities had a lower probability of health screening attendance, and they also had significantly longer inpatient stays for health care services.

CONCLUSIONS

These findings imply poor accessibility of preventive or outpatient health care services for people with severe disabilities in Korea, and suggest that barriers should be removed. Further studies are necessary for effective health care provision to meet the complex needs of people with disabilities.

Lifetime prevalence of chronic health conditions among persons with spinal cord injury

OBJECTIVE

To assess lifetime prevalence of 7 chronic health conditions (CHCs) among a cohort of adults with chronic traumatic spinal cord injury (SCI).

DESIGN

Cross-sectional.

SETTING

Rehabilitation hospital.

PARTICIPANTS

Adults with SCI who were ≥18 years of age, were ≥1 year postinjury, and had residual neurologic effects impeding full recovery (n=1678).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

CHCs were measured using questions from the Behavioral Risk Factor Surveillance System for diabetes (not including gestational), heart attack (also called a myocardial infarction), angina or coronary artery disease, stroke, hypertension (not including during pregnancy), high blood cholesterol, or cancer.

RESULTS

Of participants, 49.5% reported having at least 1 CHC, with 23.2% reporting ≥2 CHCs. The most frequently reported CHC was high cholesterol (29.3%) followed by hypertension (28.7%) and diabetes (11.8%). Although the prevalence of CHCs significantly increased with increasing age, only hypertension and cancer were significantly associated with years postinjury. Four CHCs (diabetes, coronary artery disease, hypertension, high cholesterol) were significantly related to mobility status as measured by injury level and ambulatory status. However, after controlling for age, years postinjury, sex, and race, mobility status became nonsignificant in relation to coronary artery disease, but it remained significantly associated with diabetes, hypertension, and high cholesterol.

CONCLUSIONS

Clinicians should be aware of the risk of CHCs in persons with SCI and should screen for these conditions and regular maintenance activities related to SCI.

Parallel tracks: reflections on the need for collaborative health disparities research on race/ethnicity and disability

Public policy driving health disparities research has overwhelmingly focused on racial and ethnic populations other than non-Hispanic whites; these groups have historically been and continue to be disproportionately impacted by health disparities. Only recently has public policy focused on the inclusion of people with disabilities as a distinct health disparities population. These 2 areas of research have traveled parallel paths with little recognition of the health disparities that affect people at the intersection of race, ethnicity, and disability. This commentary reflects on the history, foci, and current status of these 2 separate tracks of health disparities research. We conclude the commentary with suggestions for merging the 2 tracks to develop research that addresses both disability as well as race and ethnicity.

Difference, disparity, and disability: a comparison of health, insurance coverage, and health service use on the basis of race/ethnicity among US adults with disabilities, 2006-2008

BACKGROUND

In the United States, research on health disparities has begun to include people with disabilities as a minority population. However, there is a gap in our knowledge of whether, and to what extent, racial and ethnic disparities may affect the health or health care access of people with disabilities.

OBJECTIVES

We examined potential disparities in overall health, insurance coverage status, and health service use between non-Hispanic whites, non-Hispanic blacks, and Hispanics, among a nationally representative US sample of adults with and without disabilities (N=63,257), using both bivariate and multivariate methods. We tested 2 definitions of disparity.

RESULTS

Under the more conservative definition, we confirmed the presence of both racial and ethnic disparities in overall health, total annual health care visits, and the percentage reporting no doctor visit during the year among people with less severe disabilities; Hispanics also evidenced a disparity in rates uninsured relative to non-Hispanic whites in this group. Racial/ethnic disparities were less common among persons with more severe disabilities that affected activities of daily living or instrumental activities.

CONCLUSIONS

We conclude that the reduction of disparities between the populations of people with and without disabilities will require specific attention to racial and ethnic disparities in health, insurance coverage, and service use.

Exercise or basic body awareness therapy as add-on treatment for major depression: a controlled study

BACKGROUND

While physical exercise as adjunctive treatment for major depression has received considerable attention in recent years, the evidence is conflicting. This study evaluates the effects of two different add-on treatments: exercise and basic body awareness therapy.

METHODS

Randomized controlled trial with two intervention groups and one control, including 62 adults on antidepressant medication, who fulfilled criteria for current major depression as determined by the Mini International Neuropsychiatric Interview. Interventions (10 weeks) were aerobic exercise or basic body awareness therapy (BBAT), compared to a single consultation with advice on physical activity. Primary outcome was depression severity, rated by a blinded assessor using the Montgomery Asberg Rating Scale (MADRS). Secondary outcomes were global function, cardiovascular fitness, self-rated depression, anxiety and body awareness.

RESULTS

Improvements in MADRS score (mean change=-10.3, 95% CI (-13.5 to -7.1), p=0.038) and cardiovascular fitness (mean change=2.4ml oxygen/kg/min, 95% CI (1.5 to 3.3), p=0.017) were observed in the exercise group. Per-protocol analysis confirmed the effects of exercise, and indicated that BBAT has an effect on self-rated depression.

LIMITATIONS

The small sample size and the challenge of missing data. Participants׳ positive expectations regarding the exercise intervention need to be considered.

CONCLUSIONS

Exercise in a physical therapy setting seems to have effect on depression severity and fitness, in major depression. Our findings suggest that physical therapy can be a viable clinical strategy to inspire and guide persons with major depression to exercise. More research is needed to clarify the effects of basic body awareness therapy.

Subgroup differences in having a usual source of health care among working-age adults with and without disabilities

BACKGROUND

Having a usual source of health care is positively associated with regular health maintenance visits and receipt of preventive services. People with disabilities are, overall, more likely than those without disabilities to have a usual source of care (USC). However, the population of people with disabilities is quite heterogenous, and some segments of the population may have less access to a USC than others.

OBJECTIVE

To determine whether there are significant subgroup differences in having a USC within the U.S. population of working-age adults with disabilities, and to compare adults with and without disabilities while controlling for other subgroup differences.

METHODS

We analyzed Medical Expenditure Panel Survey annual data files from 2002 to 2008. We performed both bivariate and multivariate logistic regression analyses to examine the relationship of sociodemographic and disability subgroup variables with having a USC.

RESULTS

Within the disability population, individuals who were younger; male; Black, Hispanic, or other (non-White) race; less educated; of lower income; or uninsured for part or all of the year were significantly less likely to have a USC. These differences mirrored those among adults without disabilities. When controlling for these differences, people with physical, hearing, or multiple disabilities had greater odds of having a USC than people without disabilities, but those with vision or cognitive limitations did not differ significantly from the non-disabled referent group.

CONCLUSIONS

Disparities among people with and without disabilities are similar, underscoring the need for attention to disparities within the disability population.

Health insurance and chronic conditions in low-income urban whites

Little is known about how health insurance contributes to the prevalence of chronic disease in the overlooked population of low-income urban whites. This study uses cross-sectional data on 491 low-income urban non-elderly non-Hispanic whites from the Exploring Health Disparities in Integrated Communities-Southwest Baltimore (EHDIC-SWB) study to examine the relationship between insurance status and chronic conditions (defined as participant report of ever being told by a doctor they had hypertension, diabetes, stroke, heart attack, anxiety or depression, asthma or emphysema, or cancer). In this sample, 45.8 % were uninsured, 28.3 % were publicly insured, and 25.9 % had private insurance. Insured participants had similar odds of having any chronic condition (odds ratios (OR) 1.06; 95 % confidence intervals (CI) 0.70-1.62) compared to uninsured participants. However, those who had public insurance had a higher odds of reporting any chronic condition compared to the privately insured (OR 2.29; 95 % CI 1.21-4.35). In low-income urban areas, the health of whites is not often considered. However, this is a significant population whose reported prevalence of chronic conditions has implications for the Medicaid expansion and the implementation of health insurance exchanges.

Rural disparities in receipt of colorectal cancer screening among adults ages 50-64 with disabilities

BACKGROUND

Colorectal cancer is the third leading cause of cancer deaths in the United States. Early detection can reduce mortality; however, only 59% of U.S. adults age 50 and over meet recommended colorectal cancer screening guidelines. Studies in the general population have observed that rural residents are less likely to have received colorectal cancer screening than residents of urban areas.

OBJECTIVE

To determine whether urban/rural disparities in colorectal cancer screening exist among people with disabilities, similar to the disparities found in the general population.

METHODS

We analyzed Medical Expenditure Panel Survey annual data files from 2002 to 2008. We conducted logistic regression analyses to examine the relationship between urban/rural residence and ever having received screening for colorectal cancer (via colonoscopy, sigmoidoscopy, or fecal occult blood test).

RESULTS

Among U.S. adults ages 50-64 with disabilities, those living in rural areas were significantly less likely to have ever received any type of screening for colorectal cancer. The urban/rural difference was statistically significant regardless of whether or not we controlled for demographic, socioeconomic, health, and health care access variables.

CONCLUSIONS

Disparity in screening for colorectal cancer places rural residents with disabilities at greater risk for late stage diagnosis and mortality relative to people with disabilities in urban areas. Thus, there is a need for strategies to improve screening among people with disabilities in rural areas.

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.

Multiple chronic conditions: diabetes associated with comorbidity and shared risk factors using CDC WEAT and SAS analytic tools

BACKGROUND

Multiple chronic conditions (MCCs) are significant public health problems receiving much attention, and rightly so, because of the substantial morbidity, mortality, and cost burden.

OBJECTIVES

To report the prevalence of selected frequent MCCs with shared risk factors that are leading causes of death; and to quantify the association between diabetes and its comorbidity and shared risk factors.

METHODS

This is a cross-sectional study of 9172 participants in Pennsylvania's 2009 Behavioral Risk Factor Surveillance System (BRFSS). Centers for Disease Control and Prevention's Web Enabled Analysis Tool (WEAT) and SAS Proc Survey were used for all analyses, to account for BRFSS's multistage complex survey design and sample weights.

RESULTS

SAS estimated prevalence among ≥35-year-olds were as follows: diabetes (11.9%), heart disease (9.5%), stroke (3.3%), diabetes and heart disease (2.9%), diabetes and stroke (1.0%), heart disease and stroke (1.1%), and diabetes, heart disease, and stroke (0.4%). Adults ≥35 years old with the following characteristics were more likely to have diabetes when self-reporting: obese (adjusted odds ratio [ORAdj] = 4.63, 95% confidence interval [95% CI] = 3.41-6.30); low income (<$15 000 ORAdj = 2.85, 95% CI = 1.90-4.27; $15 000-$24 999 ORAdj = 2.07, 95% CI = 1.50-2.86; $25 000-$34 999 ORAdj = 2.06, 95% CI = 1.47-2.88; $35 000-$49 999 ORAdj = 1.51, 95% CI = 1.08-2.12); elderly ≥65 years old (ORAdj = 2.84, 95% CI = 1.76-4.56); non-Hispanic black (ORAdj = 2.54, 95% CI = 1.08-6.00); overweight (ORAdj = 1.99, 95% CI = 1.47-2.68); heart disease (ORAdj = 1.94, 95% CI = 1.47-2.56); 45 to 64 years old (ORAdj = 1.88 95%, CI = 1.21-2.93); hypertension (ORAdj = 1.78, 95% CI = 1.39-2.29); stroke (ORAdj = 1.62, 95% CI = 1.05-2.50); high cholesterol (ORAdj = 1.49, 95% CI = 1.18-1.88); physically inactive (ORAdj = 1.33 95% CI = 1.06-1.67); and men (ORAdj = 1.32, 95% CI = 1.04-1.67).

CONCLUSION

Adults with comorbidity and risk factors were 1.3 to 4.6 times more likely to have diabetes, with obesity consistently the strongest risk factor. WEAT's limitations are the predefined categories, inability to restrict to specific age groups and to estimate the prevalence of >2 MCCs. WEAT has considerable potential to advance evidence-based primary care practice and community health programs, such as state-wide programs that target obesity and physical inactivity. The robust capability of SAS to calculate MCC prevalence and adjusted associations with risk factors provides the fundamentals for developing and evaluating primary care services and community health programs.

Patterns and expenditures of multi-morbidity in an insured working population in the United States: insights for a sustainable health care system and building healthier lives

The U.S. health care system is currently heading toward unsustainable health care expenditures and increased dissatisfaction with health outcomes. The objective of this population-based study is to uncover practical insights regarding patients with 1 or more chronic illnesses. A cross-sectional investigation was designed to gather data from health records drawn from diverse US geographic markets. A database of 9.74 million fully-insured, working individuals was used, together with members in the same households. Among nearly 3.43 million patients with claims, 2.22 million had chronic conditions. About 24.3% had 1 chronic condition and 40.4% had multi-morbidity. Health care expenditures for chronic conditions accounted for 92% of all costs (52% for chronic costs and 40% for nonchronic costs). Psychiatry, orthopedics-rheumatology, endocrinology, and cardiology areas accounted for two thirds of these chronic condition costs; nonchronic condition costs were dominated by otolaryngology, gastroenterology, dermatology, orthopedics-rheumatology conditions, and preventive services. About 50.1% of all households had 2 or more members with chronic conditions. In summary, multi-morbidity is prevalent not only among those older than age 65 years but also in younger and working individuals, and commonly occurs among several members of a household. The authors suggest that the disease-focused model of medicine should change to a more holistic illness-wellness model, emphasizing not only the physical but also the mental and social elements that can influence individual health. In that way the chronic care model could be broadened in context and content to improve the health of patients and households.

Toward a conceptual model for national policy and practice considerations

Chronic diseases and conditions are serious threats to the population's health. Chronic diseases represent seven of the top ten causes of mortality in the U.S. and are major economic drivers underlying burgeoning national health costs. People with disabilities experience dramatically higher rates of some chronic conditions, but only recently has this problem been recognized. We propose a set of contributing factors and a model to help better understand the relationship of disability with chronic disease. The paper summarizes current CDC initiatives to include disability status and considerations in public health surveys and programs, exemplifying a strategy to promote inclusion of people with disabilities in mainstream programs wherever possible; use cross-disability strategies for conditions unique to people with disabilities where necessary; and implement condition-specific approaches where essential. This initial model is intended to invite dialog on a conceptual framework for preventing chronic conditions and additional functional limitations among people with disabilities.

Use of emergency departments among working age adults with disabilities: a problem of access and service needs

OBJECTIVE

To examine the relationship between emergency department (ED) use and access to medical care and prescription medications among working age Americans with disabilities.

DATA SOURCE

Pooled data from the 2006-2008 Medical Expenditure Panel Survey (MEPS), a U.S. health survey representative of community-dwelling civilians.

STUDY DESIGN

We compared the health and service utilization of two groups of people with disabilities to a contrast group without disability. We modeled ED visits on the basis of disability status, measures of health and health conditions, access to care, and sociodemographics.

DATA EXTRACTION

These variables were aggregated from the household component, the medical condition, and event files to provide average annual estimates for the period spanning 2006-2008.

PRINCIPAL FINDINGS

People with disabilities accounted for almost 40 percent of the annual visits made to U.S. EDs each year. Three key factors affect their ED use: access to regular medical care (including prescription medications), disability status, and the complexity of individuals' health profiles.

CONCLUSIONS

Given the volume of health conditions among people with disabilities, the ED will always play a role in their care. However, some ED visits could potentially be avoided if ongoing care were optimized.

Effects of physical function trajectories on later long-term care utilization among the Taiwanese elderly

AIM

The aim of this study was to examine the effects of trajectories of physical function on later long-term care utilization based on longitudinal panel data of older adults.

METHODS

A representative longitudinal sample of older adults during the years 1993 to 2007 was used (n=1232). Trajectories of physical function from 1993 to 2007 were identified by group-based trajectory analysis, and then the relationships of the past trajectories with the use of nursing homes and care assistants, and the amount of utilization used in 2007 were examined.

RESULTS

Four groups of physical function difficulties trajectories were identified: none (38.8%), little (34.1%), late increasing (16.1%) and early increasing (11.0%). The early- and late-increasing difficulty groups were more likely to use and used more nursing homes and care assistants. In particular, a long-term disability is closely related to a larger probability of using nursing homes than using care assistants at home. The utilization of care assistants seems a priority choice at the early-increasing stage of disability. When the disability worsens and lasts a long time, a nursing home is then the next choice.

CONCLUSION

Past physical function trajectories relate to later long-term care utilization.

Patient Protection and Affordable Care Act: potential effects on physical medicine and rehabilitation

The objective was to review pertinent areas of the Patient Protection and Affordable Care Act (PPACA) to determine the PPACA's impact on physical medicine and rehabilitation (PM&R). The law, and related newspaper and magazine articles, was reviewed. The ways in which provisions in the PPACA are being implemented by the Centers for Medicare and Medicaid Services and other government organizations were investigated. Additionally, recent court rulings on the PPACA were analyzed to assess the law's chances of successful implementation. The PPACA contains a variety of reforms that, if implemented, will significantly impact the field of PM&R. Many PPACA reforms change how rehabilitative care is delivered by integrating different levels of care and creating uniform quality metrics to assess quality and efficiency. These quality metrics will ultimately be tied to new, performance-based payment systems. While the law contains ambitious initiatives that may, if unsuccessful or incorrectly implemented, negatively impact PM&R, it also has the potential to greatly improve the quality and efficiency of rehabilitative care. A proactive approach to the changes the PPACA will bring about is essential for the health of the field.
