Impact of depressive symptoms on direct medical cost among medicare recipients with knee osteoarthritis

ObjectiveDepressive symptoms are prevalent among knee osteoarthritis (KOA) patients and may lead to additional medical costs. We compared medical costs in Medicare Current Beneficiary Survey (MCBS) respondents with KOA with and without self-reported depressive symptoms. MethodsWe identified a KOA cohort using ICD-9/10 diagnostic codes in both Part A and Part B claims among community-dwelling MCBS respondents from 2003-2019. We determined the presence of depressive symptoms using self-reported data on sadness or anhedonia. We considered three groups: 1) without depressive symptoms, 2) with depressive symptoms, no billable services, and 3) with depressive symptoms and billable services. We used a generalized linear model with log-transformed outcomes to compare annual total direct medical costs among the three groups, adjusting for age, gender, race, history of fall, Total Joint Replacement, comorbidities, and calendar year. ResultsThe analysis included 4,118 MCBS respondents with KOA. Of them, 27% had self-reported depressive symptoms, and 6% reported depressive symptoms and received depression-related billable services. The adjusted mean direct medical costs were $8,598/year for those without depressive symptoms, $9,239/year for those who reported depressive symptoms and received no billable services, and $14,229/year for those who reported depressive symptoms and received billable services. ConclusionWhile over one quarter of Medicare beneficiaries with KOA self-reported depressive symptoms, only 6% received billable medical services. The presence of depressive symptoms led to higher direct medical costs, even among those who did not receive depression-related billable services.

Variation in Hospice Aide Care by Residential Setting.

Background: Hospice care frequently includes hands-on care from hospice aides, but the need for hospice aide care may vary in residential settings (e.g., assisted livings and nursing homes). Objectives: The objective of this study is to compare hospice aide use and factors associated with use across residential settings. Design: This longitudinal cohort study used data from Medicare beneficiaries in the United States enrolled in the Medicare Current Beneficiary Survey (MCBS) who died between 2010 and 2019 and had hospice claims and available residential setting data in MCBS (n = 1,915). Analysis: Decedent hospice aide use was compared by residential settings; multivariable models controlling for sociodemographic, clinical/functional, and hospice characteristics examined factors associated with hospice aide care in different residential settings. Results: Hospice aide visits were least common in the community setting (64.4% vs. 76.6% vs. 72.6% with any hospice aide visits in community, assisted living, and nursing home, respectively, p = 0.001). In adjusted models, factors associated with hospice aide visits did not significantly differ by residential settings. Conclusions: Despite staff providing hands-on support in assisted livings and nursing homes, hospice aide visits were more common in residential as opposed to community settings, and factors associated with hospice aide visits were similar among settings. To maximize the potentially positive impact of hospice aides on overall care, additional work is needed to understand when hospice aides are used and how hospice aides collaborate with families and care teams. This will help to ensure that hospice care is appropriately tailored to individual care needs in all residential settings.

The Association of Retinal Disease with Vision Impairment and Functional Status in Medicare Patients

Background: The association of neovascular age-related macular degeneration (nAMD), diabetic macular edema (DME), and retinal vein occlusion (RVO) with functional status in the general Medicare population are not well established. Objectives: This study examined patient-reported survey data linked with Medicare claims to describe the burden of these vision-threatening retinal diseases (VTRDs) among Medicare beneficiaries. Methods: Medicare Current Beneficiary Survey data linked with Medicare Fee-for-Service claims data from 2006 to 2018 were used in a nationally representative retrospective pooled cross-sectional population-based comparison study. Outcomes between community-dwelling beneficiaries with nAMD (n = 1228), DME (n = 101), or RVO (n = 251) were compared with community-dwelling beneficiaries without any VTRDs (n = 104 088), controlling for baseline demographic and clinical differences. Beneficiaries with a diagnosis of nAMD, DME, or RVO during the data year were included; those with other VTRDs were excluded. Outcomes included vision function and loss, overall functioning as assessed by difficulties with activities of daily living (ADLs) and instrumental ADLs (iADLs), anxiety/depression, falls, and fractures. Results: In patient cohorts with nAMD, DME, and RVO, approximately one-third (34.2%-38.3%) reported “a little trouble seeing” (vs 28.3% for controls), and 26%, 17%, and 9%, respectively, reported “a lot of trouble seeing/blindness” (vs 5% of controls). Difficulty walking and doing heavy housework were the most reported ADLs and iADLs, respectively. Compared with those without VTRDs, beneficiaries with nAMD had higher odds of diagnosed vision loss (odds ratio [OR], 5.39; 95% confidence interval, 4.06-7.16; P < .001) and difficulties with iADLs (odds ratio, 1.41; 95% confidence interval, 1.11-1.80; P = .005); no differences were observed for DME or RVO vs control. After adjusting for age, sex, race/ethnicity, poverty status, comorbidities, and other relevant covariates, nAMD, DME, and RVO were not significantly associated with anxiety/depression, falls, or fractures. Discussion: Patients with nAMD or DME were more likely to report severe visual impairment than those without VTRDs, although only those with nAMD were more likely to be diagnosed with vision loss. Conclusions: Patients with nAMD continue to experience more vision impairment and worse functional status compared with a similar population of Medicare beneficiaries despite availability of therapies like antivascular endothelial growth factor to treat retinal disease.

Hypertension Medication and Medicare Beneficiaries: Prescription Drug Coverage Satisfaction and Medication Non-Adherence among Older Adults.

Hypertension is so prevalent and requires strict adherence to medications to prevent further disease or death, but there is no study examining factors related to prescription drug non-adherence among 65 years old and older. This study aims to assess the likelihood of medication nonadherence among patients based on factors such as age, race, and socioeconomic status, with the goal of identifying strategies to enhance medication adherence and mitigate associated health risks. Using the 2020 Medicare Current Beneficiary Survey Public Use File to represent nationwide Medicare beneficiaries (unweighted n = 3917, weighted n = 27,134,782), medication non-adherence was related to multiple independent variables (i.e., age, sex, race/ethnicity, socioeconomic status, comorbidities, insurance coverage, and satisfaction with insurance). Cross-tabulations and Wald chi-square tests were used to determine how much each variable was related to non-adherence. Multivariate logistic regression was used to examine the association between medication non-adherence and factors such as prescription drug coverage satisfaction and cost-reducing behavior. Specific trends in medication non-adherence emerged among beneficiaries. Non-adherence was higher in older adults aged 65- to 74-year-olds and those with more chronic conditions (OR = 2.24; 95% CI = 1.74-2.89). If patients were dissatisfied with the medications on the insurance formulary or struggled to find a pharmacy that accepted their medication coverage, they had worse adherence (OR = 2.63; 95% CI = 1.80-3.84). Formulary and coverage must be expanded to improve adherence to antihypertensive medications in Medicare beneficiaries. Older adults aged 65 to 74 years may be less adherent to their medications because they do not see the seriousness of the disease and could benefit from further counseling. Patients with limited activities of daily living and more comorbidities may struggle with complex treatment regimens and should use adherence assistance tools.

Health Care Contact Days Among Older Cancer Survivors.

Health care contact days-days spent receiving health care outside the home-represent an intuitive, practical, and person-centered measure of time consumed by health care. We linked 2019 Medicare Current Beneficiary Survey and traditional Medicare claims data for community-dwelling older adults with a history of cancer. We identified contact days (ie, spent in a hospital, emergency department, skilled nursing facility, or inpatient hospice or receiving ambulatory care including an office visit, procedure, treatment, imaging, or test) and described patterns of total and ambulatory contact days. Using weighted Poisson regression models, we identified factors associated with contact days. We included 1,168 older adults representing 4.51 million cancer survivors (median age, 76.4 years, 52.8% women). The median (IQR) time from cancer diagnosis was 65 (27-126) months. In 2019, these adults had mean (standard deviation) total contact days of 28.4 (27.6) and ambulatory contact days of 24.2 (23.6). These included days for tests (8.0 [8.8]), imaging (3.6 [4.1]), visits with any clinicians (12.4 [11.5]), and visits with primary care clinicians (4.4 [4.7]), and nononcology specialists (7.1 [9.4]) specifically. Sixty-four percent of days with a nonvisit ambulatory service (eg, a test) were not on the same day as a clinician visit. Factors associated with more total contact days included younger age, lower income, more chronic conditions, poor self-rated health, and tendency to "go to doctor as soon as feel bad." Older adult cancer survivors spent nearly 1 month of the year receiving health care outside the home. This care was largely ambulatory, often delivered by nononcologists, and varied by factors beyond clinical characteristics. These results highlight the need to recognize patient burdens and improve survivorship care delivery, including through care coordination.

Breast cancer screening among Medicare Advantage enrollees with dementia

BackgroundThe decision to screen for breast cancer among older adults with dementia is complex and must often be individualized, as these individuals have an elevated risk of harm from over-screening. Medicare beneficiaries with dementia are increasingly enrolling in Medicare Advantage plans, which typically promote receipt of preventive cancer screening among their enrollees. This study examined the utilization of breast cancer screening among Medicare enrollees with dementia, in Medicare Advantage and in fee-for-service Medicare.MethodsWe conducted a pooled cross-sectional study of women with Alzheimer’s disease and related dementias or cognitive impairment who were eligible for mammogram screening. We used Medicare Current Beneficiary Survey data to identify utilization of biennial mammogram screening between 2012 and 2019. Poisson regression models were used to estimate prevalence ratios of mammogram utilization and to calculate adjusted mammogram rates for Medicare Advantage and fee-for-service Medicare enrollees with dementia, and further stratified by rurality and by dual eligibility for Medicare and Medicaid.ResultsMammogram utilization was 16% higher (Prevalence Ratio [PR] 1.16; 95% CI: 1.05, 1.29) among Medicare Advantage enrollees with dementia, compared to their counterparts in fee-for-service Medicare. Rural enrollees experienced no significant difference (PR 0.99; 95% CI: 0.72, 1.37) in mammogram use between Medicare Advantage and fee-for-service Medicare enrollees. Among urban enrollees, Medicare Advantage enrollment was associated with a 21% higher mammogram rate (PR 1.21; 95% CI: 1.09, 1.35). Dual-eligible Medicare Advantage enrollees had a 34% higher mammogram rate (PR 1.34; 95% CI: 1.10, 1.63) than dual-eligible fee-for-service Medicare enrollees. Among non-dual-eligible enrollees, adjusted mammogram rates were not significantly different (PR 1.11; 95% CI: 0.99, 1.24) between Medicare Advantage and fee-for-service Medicare enrollees.ConclusionsMedicare beneficiaries age 65–74 with Alzheimer’s disease and related dementias or cognitive impairment had a higher mammogram use rate when they were enrolled in Medicare Advantage plans compared to fee-for-service Medicare, especially when they were dual-eligible or lived in urban areas. However, some Medicare Advantage enrollees with Alzheimer’s disease and related dementias or cognitive impairment may have experienced over-screening for breast cancer.

Exploring the impacts of neighborhood disadvantage on Medicare beneficiaries’ early COVID-19 vaccine uptake

A variety of factors influenced the American public's experiences with the COVID-19 pandemic and initial availability and uptake of COVID-19 vaccines. To examine variation in early COVID-19 vaccine uptake based on neighborhood disadvantage along with individual sociodemographic and health characteristics, we used Spring 2021 data from the Medicare Current Beneficiary Survey (MCBS), a nationally representative, longitudinal survey of the Medicare population conducted by the Centers for Medicare & Medicaid Services. Bivariate analyses showed that beneficiaries in disadvantaged neighborhoods were less likely to have received at least one vaccine dose than those in less disadvantaged neighborhoods (49.7%, SE = 1.6 versus 66.6%, SE = 1.0, p < 0.0001). After accounting for individual characteristics, the relationship between neighborhood disadvantage and vaccine uptake was not statistically significant. However, interaction effects of neighborhood disadvantage by urbanicity showed a more complex picture, where those in disadvantaged urban areas had the lowest odds of vaccine uptake (p < 0.01). The relationship between neighborhood disadvantage and vaccination is multifaceted, requiring further research to inform future vaccination efforts targeting the most vulnerable beneficiaries.

Availability and use of telehealth services among patients with ADRD enrolled in traditional Medicare vs. Medicare advantage during the COVID-19 pandemic.

The objective of this study was to examine differences in availability and use of telehealth services among Medicare enrollees according to Alzheimer's disease and related dementias (ADRD) status and enrollment in Medicare Advantage (MA) versus Traditional Medicare (TM) during the period surrounding the COVID-19 pandemic. This was a retrospective cross-sectional analysis of data from community-dwelling MA and TM enrollees with and without ADRD from the Medicare Current Beneficiary Survey (MCBS) Fall 2020 and Winter 2021 COVID-19 Supplement Public Use Files. We examined self-reported availability of telehealth service before and during the COVID-19 pandemic and use of telehealth services during COVID-19. We analyzed marginal effects under multivariable logistic regression. There were 13,700 beneficiaries with full-year enrollment in MA (6,046) or TM (7,724), 518 with ADRD and 13,252 without ADRD. Telehealth availability during COVID-19 was positively associated with having a higher income (2.81 pp. [percentage points]; 95% CI: 0.57, 5.06), having internet access (7.81 pp.; 95% CI: 4.96, 10.66), and owning telehealth-related technology (3.86; 95% CI: 1.36, 6.37); it was negatively associated with being of Black Non-Hispanic ethnicity (-8.51 pp.; 95% CI: -12.31, -4.71) and living in a non-metro area (-8.94 pp.; 95% CI: -13.29, -4.59). Telehealth availability before COVID-19 was positively associated with being of Black Non-Hispanic ethnicity (9.34 pp.; 95% CI: 3.74, 14.94) and with enrollment in MA (4.72 pp.; 95% CI: 1.63, 7.82); it was negatively associated having dual-eligibility (-5.59 pp.; 95% CI: -9.91, -1.26). Telehealth use was positively associated with being of Black Non-Hispanic ethnicity (6.47 pp.; 95% CI: 2.92, 10.01); it was negatively associated with falling into the age group of 75+ years (-4.98 pp.; 95% CI: -7.27, -2.69) and with being female (-4.98 pp.; 95% CI: -7.27, -2.69). Telehealth services were available to and used by Medicare enrollees with ADRD to a similar extent compared to their non-ADRD counterparts. Telehealth services were available to MA enrollees to a greater extent before COVID-19 but not during COVID-19, and this group did not use telehealth services more than TM enrollees during COVID-19.

Medicare Part D low-income subsidies expanded in January 2024, but more needs to be done to ensure that eligible beneficiaries enroll.

The Inflation Reduction Act of 2022 extended full low-income subsidies (LIS) to a small group of Medicare Part D recipients with limited assets and incomes between 135% and 150% of the Federal Poverty Level beginning in January 2024. This policy may result in small enrollment gains among beneficiaries eligible for the new benefits, but the biggest problem with the current LIS program is underenrollment across all eligibility groups. Prior research has shown that underenrollment has been a persistent problem since the LIS program began in 2006, yet little has been done to correct the situation. To identify individual-level factors associated with failure to enroll among low-income beneficiaries eligible for both full subsidies and partial subsidies under the LIS program. We used 2019 Medicare Current Beneficiary Survey data for the study. The Medicare Current Beneficiary Survey is uniquely suited for this work because it contains administrative data on LIS enrollment plus extensive survey information on financial resources necessary to establish program eligibility. We conducted descriptive and multivariate analyses to identify factors associated with failure to enroll when eligible for either full or partial subsidies. Explanatory variables included sociodemographic characteristics, economic resources, work status, health variables, and source of prescription coverage (for nonsubsidized beneficiaries). In 2019, 73% of beneficiaries eligible for full subsidies under pre-Inflation Reduction Act LIS provisions were enrolled, compared with only 25% eligible for partial subsidies. The number of those estimated to be eligible for full subsidies but not enrolled (N = 3.9 million) was more than double that of those eligible but not enrolled for partial subsidies (N = 1.5 million). Factors associated with failure to enroll (older age, male sex, White race, married, higher education, higher income and assets, and excellent/very good health status) were similar for both groups. In multivariate analyses, the single strongest predictor of failure to enroll was receipt of income from work (odds ratio = 5.50; P < 0.001). Among the nonenrolled, 64% eligible for full subsidies and 75% eligible for partial subsidies maintained unsubsidized Part D coverage. Significant numbers of low-income Medicare beneficiaries are eligible for Part D subsidies but fail to enroll. Common characteristics distinguishing nonenrollees from enrollees include older age with higher proportions of White individuals, married individuals, higher income and assets, and better overall health. Two promising targets for increasing LIS enrollment are evidence of work income and unsubsidized Part D coverage.

Healthcare contact days among older adults living with dementia.

For older adults with dementia and their care partners, accessing health care outside the home involves substantial time, direct and indirect costs, and other burdens. While prior studies have estimated days spent by these individuals in or out of hospitals and nursing homes, ambulatory care burdens are likely substantial yet poorly understand. Therefore, we characterized "health care contact days"-days spent receiving ambulatory or institutional care-in this population. We used 2019 Medicare Current Beneficiary Survey data linked to claims for community-dwelling, ≥65-year-old adults with dementia in Traditional Medicare. We measured contact days including ambulatory days (with an office visit, test, imaging, procedure, or treatment) and institutional days (spent in an emergency department, hospital, skilled nursing facility, or hospice facility). We described variation and patterns in contact days. Using multivariable Poisson regression, we identified sociodemographic and clinical factors associated with contact days. In weighted analyses, 887 older adults with dementia (weighted: 2.9 million) had mean (SD) 31.1 (33.7) total contact days/year, of which 21.7 (20.6) were ambulatory. Ten percent had ≥68 contact days in the year. One-third (34%) of ambulatory contact days involved multiple services. In multivariable models, receipt of more ambulatory contact days was associated with younger age (65-74 reference vs. -32.3% [95% CI: -42.2%, -20.7%] for 85+), higher income (>200% Federal Poverty Level [FPL] reference versus -16.6% [95% CI: -26.7%, -5.0%] for ≤200% FPL), and lack of functional impairment (reference versus -14.6% [95% CI: -23.7%, -4.4%]). Each additional chronic condition was associated with 8.2% (95% CI: 6.7%, 9.8%) more ambulatory contact days. Older adults with dementia spent 31 days a year accessing care which was mostly ambulatory. These days varied widely by both clinical and sociodemographic factors. These results highlight the need to reduce patient burden through strategies such as reducing unneeded care, coordinating care, and shifting care to home settings through telemedicine and home care.

Health Care Contact Days Among Older Adults in Traditional Medicare : A Cross-Sectional Study.

Days spent obtaining health care outside the home can represent not only access to needed care but also substantial time, effort, and cost, especially for older adults and their care partners. Yet, these "health care contact days" have not been characterized. To assess composition of, variation and patterns in, and factors associated with contact days among older adults. Cross-sectional study. Nationally representative 2019 Medicare Current Beneficiary Survey data linked to claims. Community-dwelling adults aged 65 years and older in traditional Medicare. Ambulatory contact days (days with a primary care or specialty care office visit, test, imaging, procedure, or treatment) and total contact days (ambulatory days plus institutional days in a hospital, emergency department, skilled-nursing facility, or hospice facility); multivariable mixed-effects Poisson regression to identify patient factors associated with contact days. In weighted results, 6619 older adults (weighted: 29 694 084) had means of 17.3 ambulatory contact days (SD, 22.1) and 20.7 total contact days (SD, 27.5) in the year; 11.1% had 50 or more total contact days. Older adults spent most contact days on ambulatory care, including primary care visits (mean [SD], 3.5 [5.0]), specialty care visits (5.7 [9.6]), tests (5.3 [7.2]), imaging (2.6 [3.9]), procedures (2.5 [6.4]), and treatments (5.7 [13.3]). Half of the test and imaging days were not on the same days as office visits (48.6% and 50.1%, respectively). Factors associated with more ambulatory contact days included younger age, female sex, White race, non-Hispanic ethnicity, higher income, higher educational attainment, urban residence, more chronic conditions, and care-seeking behaviors (for example, "go to the doctor…as soon as (I)…feel bad"). Study population limited to those in traditional Medicare. On average, older adults spent 3 weeks in the year getting care outside the home. These contact days were mostly ambulatory and varied widely not only by number of chronic conditions but also by sociodemographic factors, geography, and care-seeking behaviors. These results show factors beyond clinical need that may drive overuse and underuse of contact days and opportunities to optimize this person-centered measure to reduce patient burdens, for example, via care coordination.

Enrollment Patterns of Medicare Advantage Beneficiaries by Dental, Vision, and Hearing Benefits

Most Medicare beneficiaries now choose to enroll in Medicare Advantage (MA) plans. Racial and ethnic minority group and low-income beneficiaries are increasingly enrolling in MA plans. To examine whether dental, vision, and hearing supplemental benefits offered in MA plans are associated with the plan choices of traditionally underserved Medicare beneficiaries. This exploratory observational cross-sectional study used data from the 2018 to 2020 Medicare Current Beneficiary Survey linked to MA plan benefits. The nationally representative sample comprised primarily community-dwelling MA beneficiaries enrolled in general enrollment MA plans. Data analysis was performed between April and October 2023. Beneficiary self-identified race and ethnicity and combined individual and spouse income and educational attainment. Binary indicators were developed to determine whether beneficiaries were enrolled in a plan offering any dental, comprehensive dental, any vision, eyewear, any hearing, or hearing aid benefit. Mixed-effects logistic regression models were estimated to report average marginal effects adjusted for beneficiary-level demographic and health characteristics, plan attributes, and plan availability. This study included 8139 (weighted N = 31 million) eligible MA beneficiaries, with a mean (SD) age of 77.7 (7.5) years. More than half of beneficiaries (54.9%) were women; 9.8% self-identified as Black, 2.0% as Hispanic, 83.9% as White, and 4.2% as other or multiple races or ethnicities. Plan choices by dental benefits were examined among 7516 beneficiaries who were not enrolled in any dental standalone plan, by vision benefits for 8026 beneficiaries not enrolled in any vision standalone plan, and by hearing benefits for 8131 beneficiaries not enrolled in any hearing standalone plan. Black beneficiaries were more likely to enroll in plans with any dental benefit (9.0 percentage points [95% CI, 3.4-14.4]; P < .001), any comprehensive dental benefit (11.2 percentage points [95% CI, 5.7-16.7]; P < .001), any eye benefit (3.0 percentage points [95% CI, 1.0 to 5.0]; P = .004), or any eyewear benefit (6.0 percentage points [95% CI, 0.6-11.5]; P = .03) compared with White beneficiaries. Lower-income individuals (earning ≤200% of the federal poverty level) were more likely to enroll in a plan with a comprehensive dental benefit (4.4 percentage-point difference [95% CI, 0.1-7.9]; P = .01) compared with higher-income beneficiaries. Beneficiaries without a college degree were more likely to enroll in a plan with a comprehensive dental benefit (4.7 percentage-point difference [95% CI, 1.4-8.0]; P = .005) compared with those with higher educational attainment. The results of this study suggest that racial and ethnic minority individuals and those with lower income or educational attainment are more likely to choose MA plans with dental or vision benefits. As the federal government prepares to adjust MA plan star ratings for health equity, implements MA payment cuts, and allows increasing flexibility in supplemental benefit offerings, these findings may inform benefit monitoring for MA.

Bidirectional associations between alcohol drinking and depressive symptom scores among US older adults

BackgroundThis study examines the bidirectional associations between alcohol drinking and depression in which low to moderate alcohol drinking may reduce the risk of depression, while the occurrence of depression may increase the amount of alcohol drinking as a coping strategy. MethodData for the community-dwelling older adults from the Medicare Current Beneficiary Survey (MCBS) 2016 to 2019 were analyzed using random intercept cross-lagged panel models to explore the within-individual causal associations for males and females separately. Socioeconomic status (SES), smoking and comorbidities were adjusted in the models. ResultsAmong 3388 older adults with three measures for the number of alcohol drinks and Patient Health Questionnaire (PHQ) depression scores, a prior increase in the number of drinks was related to a moderate non-significant decrease in PHQ scores in the follow-up, but a previous increase in the PHQ scores was significantly associated with a decrease in the number of drinks at the follow-up visit in the adjusted models (regression coefficient = −0.144, p = 0.017 for males; and coefficient = −0.11, p < 0.001 for females). ConclusionPrior depression may lead to reduced drinking in the follow up visits, but no bidirectional association was found among US older adults.

Satisfaction With Care Among Cancer Survivors With Medicare Coverage: Are There Rural Versus Urban Inequities?

Rural cancer survivors often face greater barriers to treatment, which may translate into worse satisfaction with health care. To examine rural versus urban differences in satisfaction with health care among Medicare cancer survivors. Data are from the 2020 Medicare Current Beneficiary Survey (MCBS). Rao-Scott chi-square analyses were conducted to examine rural versus urban inequities in satisfaction with 9 dimensions of health care (health professionals' concern for health, information about what was wrong, ease/convenience from home, ease of obtaining answers over telephone, getting needs taken care of at same location, availability of specialists, overall quality, and out-of-pocket costs, and availability of care at night/on weekends). Multiple logistic regression analyses were conducted to test for rural/urban differences while adjusting for race/ethnicity, gender, marital status, educational attainment, health insurance (traditional Medicare, Medicare Advantage, dual Medicaid coverage, employer, or self-purchased insurance), and self-rated overall health. Rural cancer survivors were less satisfied with the ease/convenience of getting to health professionals (93.35% rural and 96.87% urban) and less satisfied with getting all health care needs taken care of at the same location (88.32% rural and 92.22% urban). These rural/urban differences persisted when adjusting for other factors. Health care providers serving rural areas may need to consider new strategies to satisfy some of the unique needs of rural cancer survivors, such as better organizing services at single clinic sites and utilizing telehealth when feasible to reduce the need to travel for in-person services.

VARIATION IN USE OF HOSPICE AIDES BY RESIDENTIAL SETTING

Abstract Hospice care frequently includes visits from hospice aides, but need for hospice aide care may be different for those in the community compared to settings like assisted living or nursing homes where personal care is routinely provided. The objective of this longitudinal cohort study is to identify factors associated with hospice aide visits (any versus none) and frequency of hospice aide visits (proportion of routine hospice cays with an aide visit) in different residential settings (community, assisted living, and nursing home). We identified Medicare beneficiaries enrolled in the Medicare Current Beneficiary Survey (MCBS) who died between 2010-2019 (n=1,915). We used self-reported survey responses, Medicare claims data, and Medicare Provider of Service data to compare decedent hospice care experience across residential settings and estimated multivariable models to compare factors associated with hospice aide visits among residential settings. Hospice aide visits were least common in the community setting (64.4% vs 76.6% vs 72.6% with any hospice aide visits in community, assisted living, and nursing home respectively, p=0.002). In models adjusted for sociodemographic, clinical/functional, and hospice factors, neither hospice aide visits nor the proportion of routine hospice days with hospice aide visits varied significantly by residential settings. Future work to understand when and why hospice aides are utilized and how hospice aides collaborate with families and existing care teams in will help ensure that hospice care is appropriately tailored to individual care needs in all residential settings.

CAUSAL EFFECT OF ANTI-DEMENTIA DRUGS ON PATIENTS’ ECONOMIC BURDEN USING DOUBLE/DEBIASED MACHINE LEARNING APPROACH

Abstract Alzheimer’s disease and related dementia (ADRD) present a significant public health challenge and carry a substantial financial burden. Exploring avenues for treatment, the administration of anti-dementia drugs has emerged as a potential intervention for ADRD. However, prior research has been susceptible to omitted variable bias due to data limitations and struggled to establish causal relationships due to confounding by indication. Our study aims to uncover the causal impact of anti-dementia drug utilization on the economic burden among ADRD patients through Double/Debiased Machine Learning (DML) method. Leveraging data from the Medicare Current Beneficiary Survey (MCBS) spanning 2015 to 2017, we utilized a nationally representative survey linked to Medicare data, providing comprehensive insights. DML techniques, including Random Forest (RF) regression and Least Absolute Shrinkage and Selection Operator (LASSO) regression algorithms, were employed to investigate the causal effect. After exclusion and inclusion, a total of 218,237 ADRD patients used anti-dementia drugs, with an average total medical cost of $16,695.87; 95.51% (4,646,408 patients) of ADRD patients did not use anti-dementia drug, with an average total medical cost of $27,567.09. Results from generalized linear regression showed that anti-dementia drug use did not have a significant impact on total medial cost (β = -0.29, P = 0.10). However, results from DML demonstrated a significant true effect [RF regression (β = -0.85, P = 6.79×10-3), LASSO regression (β = -0.78, P = 9.95×10-3)]. To conclude, our analysis demonstrated the causal effect of anti-dementia drug utilization in reducing overall medical costs borne by ADRD patients.

HYPERTENSION SELF-CARE AMONG MEDICARE BENEFICIARIES WITH SELF-REPORTED HEARING TROUBLE

Abstract Hearing loss is common in older adults and frequently comorbid with chronic illnesses like hypertension, which requires self-care practices learned through patient-provider health communication. However, hearing loss is a barrier to communication. This cross-sectional analysis used the 2020 Medicare Current Beneficiary Survey of (N=11,587; weighted estimate, 51.8 million) to characterize hypertension self-care outcomes (measuring blood pressure, taking blood pressure medications, reducing alcohol, and confidence in blood pressure control) by hearing status among Medicare beneficiaries ages &amp;gt;65. In the sample, 39% reported a little and 6% reported a lot of trouble hearing while 66% reported having received a hypertension diagnosis. In models adjusted for sociodemographic and health variables, Medicare beneficiaries with a little trouble hearing (OR=0.84 95% CI=0.72-0.97; P=0.02) and a lot of trouble hearing (OR=0.74; CI 0.57-0.95; P=0.02) had 16% and 26% reduced odds of reporting confidence in hypertension control compared to beneficiaries with no hearing trouble. Similar results were found when excluding hearing aid users (a little trouble hearing OR=0.85; CI=0.72-1.01; P=0.06; a lot of trouble hearing OR=0.69; 95% CI=0.52-0.91; P=0.01). No significant difference was found for other self-care outcomes. To the authors’ knowledge, this is the first characterization of hearing difficulty and hypertension self-care and findings align with previous work suggesting hearing loss may be a barrier to vital health communication. Future work should focus on examining self-care activities across chronic illnesses, temporal relationships, and designing population-appropriate interventions to improve self-care understanding among adults with hearing loss.

DIFFERENCES IN MEDICARE RESOURCE USE BY ENGLISH PROFICIENCY

Abstract Medicare is complicated and coverage decisions can be complex. Accordingly, the Centers for Medicare &amp; Medicaid Services (CMS) provides a hotline, handbook, and website to help Medicare beneficiaries understand their benefits and coverage options. In this study, we used 2016-2018 Medicare Current Beneficiary Survey data and linear probability models to assess whether the likelihood of CMS Medicare resource use differed between beneficiaries with English proficiency and those with limited English proficiency (LEP). Our primary outcome was an indicator of having used at least one CMS resource. We considered English proficiency in both speaking and reading. Limited English-speaking proficiency or, separately, limited English-reading proficiency signified that the beneficiary reported speaking or reading English “not well” or “not at all.” Among a nationally representative sample of noninstitutionalized Medicare beneficiaries, 5.7% had limited English-speaking proficiency, 8.7% had limited English-reading proficiency, and 67.0% had used a CMS resource. Adjusting for health and social factors, age, language spoken at home, county-level Medicare Advantage characteristics, and state and year fixed effects, beneficiaries with limited English-reading proficiency were 16.7 percentage points less likely to have used a CMS resource compared to beneficiaries who reported reading English “well” or “very well” (p &amp;lt;.001). Limited English-speaking proficiency was not associated with CMS resource use. These findings have implications for federal initiatives to improve language access in Medicare, particularly efforts to reduce literacy barriers. Differences in Medicare coverage choice and benefits utilization among beneficiaries with LEP may be partially explained by differential access to or engagement with written CMS Medicare information.
