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

People with Disabilities' Access to Medical Care During the COVID-19 Pandemic

Delaying and forgoing medical care intensifies the health disparities and unmet needs people with disabilities already face. While many people with disabilities were at high risk for COVID-19, less is known about their access to medical care during the pandemic. This study explored people with disabilities' access to medical care during the COVID-19 pandemic. We analyzed United States Census Bureau COVID-19 Household Pulse Survey data from the second year of the pandemic (April-July 2021) from people with (n = 38,512) and without (n = 296,260) disabilities. During the second year of the pandemic, 30.8% of people with disabilities delayed getting medical care and 28.9% forwent needed care. People with disabilities were also significantly more likely to delay and forgo medical care than people without disabilities. Attention must be drawn to the unmet needs of people with disabilities and efforts must be made to expand their access to health care.

Status of the utilization of preventive care services and its associated socio-demographic factors among Iranian elderly

Introduction

The growing population of the elderly, the rising costs of medical care and the low use of preventive services are three factors that highlight the importance of using preventive health care services in the Iranian population. This study aimed to determine the status of the use of preventive care services and its associated socio-demographic factors in the elderly referred to health centers.

Methods

In this analytical cross-sectional study, a number of 160 elderly people referred to health centers in East Guilan, Iran was selected by multi-stage cluster sampling. Data were obtained from May to September, 2021 using a questionnaire containing utilization of preventive care services (9 items) and socio-demographic characteristics.

Results

The highest and the lowest utilization rates of preventive care services among study participants were related to the blood pressure test (96.9%) and colonoscopy (17.5%), respectively. Multivariate analysis showed that only income had a significant association with performing fasting blood sugar test (p = 0.004), blood lipid test (p = 0.004), and blood pressure test (p = 0.013). Also, the associations between having an underlying disease and performing fasting blood sugar test (p = 0.032) and blood pressure test (p = 0.002), the association between gender and performing the bone mineral density test (p < 0.001), and the association between occupation and performing Pap-smear test (p = 0.011), were statistically significant.

Conclusions

The utilization rates of screening tests for most cancers, including gastrointestinal cancers, were low. Since, there were a significant association between income, disease, gender and occupation with the utilization of some preventive care services, considering them in health centers' preventive care program design might be useful.

Factors Associated with Lack of Health Screening among People with Disabilities Using Andersen's Behavioral Model

People with disabilities often have poorer health than the general population, and many do not participate in preventive care. This study aimed to identify the health screening participation rates of such individuals and investigate why they did not receive preventive medical services based on Andersen's behavioral model, using data from the Survey on Handicapped Persons with Disabilities. The non-participation health screening rate for people with disabilities was 69.1%. Many did not in health screening because they showed no symptoms and were considered healthy, in addition to poor transportation service and economic limitations. The binary logistic regression result indicates that younger age, lower level education, and unmarried as predisposing characteristics; non-economic activity as the enabling resources; and no chronic diseases, severe disability grade, and suicidal ideation as need factor variables were the strongest determinants of non-participation health screening. This indicates that health screening of people with disabilities should be promoted while takings into account the large individual differences in socioeconomic status and disability characteristics. It is particularly necessary to prioritize ways to adjust need factors such as chronic disease and mental health management, rather than focusing on uncontrollable predisposing characteristics and enabling resources among barriers to participation in health screening for people with disabilities.

Musculoskeletal diagnoses, comorbidities, and physical and occupational therapy use among older adults with and without cerebral palsy

BACKGROUND

Musculoskeletal (MSK) disorder in adults with cerebral palsy (CP) is higher than in the general population. Evidence lacks about physical therapy (PT) and occupational therapy (OT) service utilization among older adults (65> years) living with CP.

OBJECTIVE

We compared the presence of comorbidities and patterns of PT and OT use among older adults with and without CP seeking care for MSK disorders.

METHODS

A 20% national sample of Medicare claims data (2011-2014) identified community-living older adults with (n = 8796) and without CP (n = 5,613,384) with one or more ambulatory claims for MSK diagnoses. The sample matched one CP case to two non-CP cases per year on MSK diagnoses, age, sex, race, dual eligibility, and census region. Exposure variable was the presence/absence of a CP diagnosis. Outcomes were use of PT and OT services identified via CPT and revenue center codes, and the presence/absence of Elixhauser comorbidities.

RESULTS

In older adults with MSK diagnoses, less than a third regularly utilized PT and/or OT services, and adults with CP utilized significantly less PT than adults without CP, and for some MSK diagnoses had fewer visits than their matched peers. Older adults with CP were at greater risk for secondary conditions that influence morbidity, mortality, and quality of life compared to their age-matched peers without CP.

CONCLUSIONS

Older adults with CP and MSK diagnoses had a greater prevalence of numerous comorbidities and lower use of PT services relative to their non-CP peers.

Misclassification of Medicaid Participation by Dual Eligibles: Evidence From the Medicare Current Beneficiary Survey

Previous studies show that survey-based reports of Medicaid participation are measured with error, but no prior study has examined measurement error in an important segment of the Medicaid population-low-income adults enrolled in Medicare. Using the Medicare Current Beneficiary Survey, we examine whether respondent self-reports of Medicaid enrollment match administrative records and present several key findings. First, among low-income Medicare beneficiaries, the false negative rate is 11.5% when the self-report is interpreted as full Medicaid and 3.7% when the self-report is interpreted as full or partial Medicaid. Second, the likelihood of a false negative report is systematically associated with respondent traits. Third, systematic measurement error results in biased coefficient estimates in models of Medicaid participation defined from self-reports, and the bias is more significant when the researcher interprets self-reports as full Medicaid coverage only. Researchers should use caution when interpreting survey reports as pertaining to full Medicaid coverage only.

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.

Identifying Gender Minority Patients' Health And Health Care Needs In Administrative Claims Data

Health care utilization patterns for gender minority Medicare beneficiaries (those who are transgender or gender nonbinary people) are largely unknown. We identified gender minority beneficiaries using a diagnosis-code algorithm and compared them to a 5 percent random sample of non-gender minority beneficiaries from the period 2009-14 in terms of mental health and chronic diseases, use of preventive and mental health care, hospitalizations, and emergency department (ED) visits. Gender minority beneficiaries experienced more disability and mental illness. When we adjusted for age and mental health, we found that they used more mental health care. And when we adjusted for age and chronic conditions, we found that they were more likely to be hospitalized and to visit the ED. There were several small but significant differences in preventive care use. Findings were similar for disabled and older cohorts. These findings underscore the need to capture gender identity in health data to better address this population's health needs.

Geographic Variation in Use of Vestibular Testing among Medicare Beneficiaries

Objective

There is a lack of consensus regarding the indications for vestibular testing in the evaluation of dizziness and balance disorders. Geographic variation in health services utilization is associated with lack of consensus. To understand the variation in current practice, we investigated the patterns of use of vestibular testing and diagnosis codes for dizziness and balance disorders among individuals ≥65 years of age across different regions of the United States.

Study Design

Cross-sectional study.

Setting

Medicare administrative claims data.

Subjects and Methods

Using the Summarized Denominator file, a sample of the US population linked to the Surveillance, Epidemiology, and End Results (SEER)–Medicare files (years 2000-2010), we identified persons who were ≥65 years of age. We used multivariable analyses to determine the factors associated with vestibular testing and diagnoses.

Results

Of the 231,984 eligible Medicare beneficiaries, 27% were diagnosed with dizziness and balance disorders. Patterns of use of vestibular tests (eye movement recording for spontaneous nystagmus, caloric testing, and rotary chair testing) varied significantly by geographic region. Rotary chair test utilization varied most. We found significant geographic variation in vestibular testing and diagnoses after controlling for age, sex, race, Medicaid participation, and rurality.

Conclusions

There may be opportunities to improve the consistency and efficiency of care for dizziness and balance disorders. It will be important to define appropriate levels of vestibular diagnostic testing and which tests add sufficient value to justify the costs. Further work is needed to better characterize the causes and consequences of variation in vestibular test utilization.

Younger Dual-Eligibles Who Use Federally Qualified Health Centers Have More Preventable Emergency Department Visits, but Some Have Fewer Hospitalizations

OBJECTIVE

To determine whether younger dual-eligibles receiving care at federally qualified health centers (FQHCs) have lower rates of ambulatory care sensitive (ACS) hospitalization and emergency department (ED) visits.

DATA SOURCES

We used the 100% Medicare Part A and Part B institutional claims from 2007 to 2010 for dual-eligibles younger than 65 years, enrolled in traditional fee-for-service Medicare, who received care at an FQHC or lived in a primary care service area with an FQHC.

METHODS

Our cross-sectional analysis used negative binomial regressions to model ACS hospitalizations and ED visits as a function of prior year FQHC use. The model adjusted for beneficiary age, gender, race, and chronic diseases, as well as county fixed effects, time trends, and race-FQHC use interactions.

RESULTS

FQHC use is associated with a decrease in ACS hospitalization rates for whites (2.8 per 1000 persons), but an increase among blacks (2.5 per 1000 persons). FQHC use is also associated with an increase in ACS ED visits, from 27 to 33 more visits per 1000 persons per year, depending on patient race.

CONCLUSIONS

ACS hospital use is higher for FQHC users than nonusers, but white FQHC users have fewer ACS hospitalizations. More research is needed to understand how this relationship varies within and between centers.

Trends in Pap Testing Over Time for Women With and Without Chronic Disability

INTRODUCTION

Data from 20 years ago--shortly after passage of the Americans with Disabilities Act--showed that women with significant mobility disability had 40% lower Pap test rates than other women.

METHODS

To examine whether disability disparities in Pap test rates have diminished over time, this study analyzed National Health Interview Survey responses from selected years between 1998 and 2010 from women aged 21-65 years without histories of cervical cancer or hysterectomy. Seven chronic disability types were identified using self-reported functional impairments or participation limitations. Self-reported Pap testing within the previous 3 years was studied. Bivariable analyses and multivariable logistic regression analyses controlling for sociodemographic variables were conducted in 2014.

RESULTS

Rates of all chronic disability types increased over time. Pap test rates remained relatively constant over time for all women, holding around 84%-87%. Bivariable analyses found statistically significantly lower rates of Pap testing for women with disability compared with nondisabled women. Multivariable analyses failed to find consistent evidence of lower Pap test rates among women across disability types compared with nondisabled women. In 2010, the AOR for reporting Pap testing for women noting the most severe movement difficulty compared with nondisabled women was 0.35 (95% CI=0.15, 0.79). However, the AOR for this disability type varied over time.

CONCLUSIONS

Little has changed over time in Pap test rates for all women. Women with certain disabilities continue to experience disparities compared with nondisabled women in receipt of this important screening test.

Examining access to care for younger vs. older dual-eligible adults living in the community

BACKGROUND

Recent state dual-eligible (Medicare and Medicaid) payment reform demonstrations have included groups of both working-age and older adults, but relatively little is known about how access to care varies between these two populations.

OBJECTIVES/HYPOTHESIS

To examine access to a usual source of care for younger and older dual-eligible adults, to analyze whether timely access to several types of care differed in these two populations, and to understand some of the underlying reasons for delayed care among younger and older dual-eligibles.

METHODS

Using observations pooled across calendar years 2003-2012 of the Medical Expenditure Panel Survey, this study conducted descriptive and multivariate analyses to examine access to care measures.

RESULTS

Younger dual-eligible adults were more likely to encounter problems with accessing medical care, dental care, and prescription medications than older dual-eligible adults. Both groups of dual-eligible adults reported that a lack of affordability, gaps in existing insurance coverage, and difficulty in getting to a provider's office were the most common reasons for delayed access to care.

CONCLUSIONS

A lack of affordability for medical care, dental care, and prescription medications suggests that high co-payments and cost sharing for some services may be deterring access to needed care. Younger dual-eligibles were more likely to encounter service coverage gaps than older dual-eligibles. States should monitor Medicare-Medicaid plans to confirm they have adequate provider networks.

Trends in mammography over time for women with and without chronic disability

BACKGROUND

Women with disabilities often receive mammograms at lower rates than do nondisabled women, although this disparity varies by disability type and severity. Given the implementation of disability civil rights laws in the early 1990s, we examined whether disability disparities in mammogram use have diminished over time.

METHODS

We analyzed National Health Interview Survey responses of civilian, noninstitutionalized United States female residents 50 to 74 years old from selected years between 1998 and 2010. We identified seven chronic disability types using self-reported functional impairments, activity/participation limitations, and expected duration. We conducted bivariable and multivariable logistic regression analyses examining associations of self-reported mammogram use within the previous two years with sociodemographic factors and disability.

RESULTS

Most chronic disability rates rose over time. The most common disability was movement difficulties, with rates increasing from 35.6% (1998) to 39.8% (2010). Mammogram rates for all women remained relatively stable over time, ranging from 72% to 75%. Bivariable analyses generally found statistically significantly lower mammogram rates for women with disability versus nondisabled women. Over time, disparities grew significantly between women with any basic action difficulty or complex activity limitation and nondisabled women (p<0.01). In multivariable logistic analyses, having any difficulty with basic actions was significantly associated with lower adjusted odds of mammography; for example, adjusted odds [95% confidence interval]=0.5 [0.3-0.8], p=0.006, in the model involving movement disability.

CONCLUSIONS

Little has changed since 1998 in mammogram rates for women with versus without disabilities. Women with certain disabilities continue to experience disparities in mammography testing.

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.

Reducing Obesity Among People With Disabilities

Achieving healthy weight for people with disabilities in the United States is a challenge. Obesity rates for adults and children with disabilities are significantly higher than for those without disabilities, with differences remaining even when controlling for other factors. Reasons for this disparity include lack of healthy food options for many people with disabilities living in restrictive environments, difficulty with chewing or swallowing food, medication use contributing to changes in appetite, physical limitations that can reduce a person's ability to exercise, constant pain, energy imbalance, lack of accessible environments in which to exercise or fully participate in other activities, and resource scarcity among many segments of the disability population. In order for there to be a coordinated national effort to address this issue, a framework needs to be developed from which research, policy, and practice can emerge. This paper reviews existing literature and presents a conceptual model that can be used to inform such a framework, provides examples of promising practices, and discusses challenges and opportunities moving forward.
