Welcome mats and on-ramps for older adults: the impact of the Affordable Care Act's Medicaid Expansions on Dual Enrollment in Medicare and Medicaid.
The authors examined whether Medicaid participation by low-income adults age 65 and up increased as a result of Medicaid expansions to working-age adults under the Affordable Care Act (ACA). Using American Community Survey data and state variation in ACA Medicaid expansions, they found that Medicaid expansions to working-age adults increased Medicaid participation among low-income older adults by 4.4 percent. They also found evidence of an “on-ramp” effect, which is an important mechanism behind welcome mat effects among some older adults.

Comparison of diabetes medications used by adults with commercial insurance vs Medicare Advantage, 2016 to 2019.
Investigators sought to compare trends in initiation of treatment with GLP-1RA, SGLT2i, and DPP-4i by older adults with type 2 diabetes insured by Medicare Advantage vs commercial health plans. They found that Medicare Advantage beneficiaries may be less likely than commercially insured beneficiaries to be treated with newer medications to lower glucose levels, with greater disparities among lower-income patients. They recommended further investigation of nonclinical factors contributing to treatment decisions and efforts to promote greater equity in diabetes management.

Trends in poor health indicators among Black and Hispanic middle-aged and older adults in the United States, 1999-2018.
This study used records extracted from the Behavioral Risk Factor Surveillance System to determine which health indicators have improved or became worse among Black and Hispanic middle-aged (45 and older) adults compared to Whites from 1999 to 2018. This data is required by the Minority Health and Health Disparities Research and Education Act of 2000. A sample included of 4,856,326 participants, of them 60.9% women, mean age 60.4. During the last 20 years, Black adults showed an overall decrease showing improvement in uninsured status and physical inactivity while showing an overall increase in hypertension, diabetes, asthma, and stroke, and also the same increases and decreases in the Black-White gap. Hispanic adults showed improvement in physical inactivity and perceived poor health, while they showed overall deterioration in hypertension and diabetes. The Hispanic-White gap improved in coronary heart disease, stroke, kidney disease, asthma, arthritis, depression and physical inactivity while it increased for diabetes, hypertension, and uninsured status.

Cognition and take-up of the Medicare Savings Programs.
In this study, the investigators examined the association between cognition and Medicare Savings Program (MSP) enrollment among elderly Medicare beneficiaries who qualified for these programs. They also examined enrollment in the Low-Income Subsidy (LIS), a separate program that provides premium and cost-sharing assistance in Medicare Part D that Medicare beneficiaries automatically received if they are enrolled in an MSP.

Medicare accountable care organizations reduce spending on surgery.
This study examined the impact that Medicare accountable care organization (ACO) alignment has on spending for inpatient and outpatient surgical care. Researchers identified adults 65 years of age and older enrolled in fee-for-service Medicare from among a 20% random sample of beneficiaries and distinguished between those aligned and unaligned with a Medicare ACO, then measured payments for surgical services made on the enrollees’ behalf. Findings showed that ACO alignment was associated with savings on surgical care. These savings resulted from increased outpatient surgery and reduced use of inpatient surgery as well as reduced spending per inpatient surgical episode. Greater focus on surgical care to improve the ability of ACOs to control healthcare spending was recommended.

The impact of health insurance expansion on physician treatment choice: Medicare Part D and physician prescribing.
Researchers tested the effect of the introduction of Medicare Part D on physician prescribing behavior using data on physician visits from the National Ambulatory Medical Care Survey (NAMCS). Subjects were patients aged 60-69. The researchers found a 32% increase in the number of prescription drugs prescribed or continued per visit and a 46% increase in the number of generic drugs prescribed or continued for the elderly after the introduction of Medicare Part D.

The demand for preventive and restorative dental services among older adults.
This study examined the use of preventive and restorative dental services among older adults. Traditional Medicare does not have dental benefits, and older adults must either be employed, have post-retirement dental benefits or spousal coverage, or enroll in a Medicare Advantage program that includes dental coverage. The authors used 2007-2015 Medical Expenditure Panel Survey and supplemental data on dental care prices to estimate the demand for dental care. Dental service was not sensitive to out-of-pocket prices. Older adults with private dental insurance increased preventive service by 25%, and dental coverage through Medicaid increased basic and major service use by 23% and 36%. Women used dental insurance more than men.

Health insurance and out-of-pocket costs in the last year of life among decedents utilizing the ICU.
The objective of this study was to estimate out-of-pocket costs in the last year of life for individuals who required intensive care in the months prior to death and to examine how these costs vary by insurance coverage. Results showed that, across all categories of insurance coverage, out-of-pocket spending in the last 12 months of life was high and represented a significant portion of assets for many patients requiring intensive care and their families. Medicare fee-for-service alone did not insulate individuals from the financial burden of high-intensity care. Medicaid was found to provide the most complete hospital coverage of all the insurance groups, as well as significantly financing long-term care.

Association between postoperative pneumonia and 90-day episode payments and outcomes among Medicare beneficiaries undergoing cardiac surgery.
Postoperative pneumonia is the most common healthcare-associated infection in cardiac surgical patients, yet their impact across a 90-day episode of care remains unknown. The objective of this study was to examine the relationship between pneumonia and 90-day episode payments and outcomes among Medicare beneficiaries undergoing cardiac surgery. The investigators concluded that postoperative pneumonia was associated with significantly higher 90-day episode payments and inferior outcomes at the patient and hospital level.

Medicaid becomes the first third-party payer to cover passive remote monitoring for home care: policy analysis.
This study examined passive remote monitoring technologies in state Medicaid programs. Its goals were to identify which states allowed location tracking, sensor systems, and cameras, what policies were in place to track usage, what implementation processes and program monitoring mechanisms were in place, and what related insights Medicaid program stakeholders would like to learn. Interviews were conducted with state, federal, and managed care organization (MCO) Medicaid program stakeholders about the use of these technologies in state waivers that served community-dwelling older adults in 15 states. While two-thirds of the states covered location tracking and activity-monitoring sensors and one-third covered cameras, only 3 states had specific service categories that allowed tracking of when they pay for these technologies. The authors conclude that technologies that have great potential to alter the way older adults receive supportive services are often used without research on their use, social or ethical implications, or outcomes. New service categories are needed to enable oversight, and more interaction between policymakers and researchers in this field would aid in the prioritization of research aims to inform practice.

Changes in case-mix and health outcomes of Medicare fee-for-service beneficiaries and managed care enrollees during the years 1992-2011.
This study examined changes in differentials between managed care enrollees (MCEs) and fee-for-service beneficiaries (FFSBs) both in case-mix and health outcomes over time. It found that the case-mix differential between MCEs and FFSBs persisted over time. Both MCEs and FFSBs were as likely to die within 2 years from the Health and Retirement Study interview.

The ACA's 65th birthday challenge: moving from Medicaid to Medicare.
Following the Affordable Care Act’s coverage expansion, many newly-insured older enrollees will lose Medicaid coverage on their 65th birthday and transition from Medicaid to Medicare as their primary insurer. This article discusses the transition in primary health insurance coverage that includes changes to benefits, patient cost-sharing, and provider reimbursement, which could have profound consequences on the use of health services and associated health outcomes for low-income seniors.

Dental use and expenditures for older uninsured Americans: the simulated impact of expanded coverage.
The purpose of this paper is to empirically determine if insurance alone would close the current gaps in dental use and expenditures between insured and uninsured older Americans. Comparing simulated dental use and expenditures rates of newly insured persons against the corresponding rates for those previously insured, the authors found that it would close previous gaps in use and expense.

Role of race and ethnicity in private long-term care insurance ownership.
The authors sought to determine if racial/ethnic disparities exist in the ownership of private long-term care insurance (LTCI) among current Medicare beneficiaries. They found that 12.3% of Blacks and 5.8% of Hispanics, compared with 20.2% of Whites, reported having LTCI coverage and that Hispanics were 48% less likely to have LTCI compared with Whites. Hispanic women were 81% less likely to be insured compared with White women.
