Medicare Advantage enrollment and outcomes of post-acute nursing home care among patients with dementia.

Enrollment in Medicare Advantage (MA) has been rapidly growing. We examined whether MA enrollment affects the outcomes of post-acute nursing home care among patients with Alzheimer's disease and related dementias (ADRD). We exploited year-to-year changes in MA penetration rates within counties from 2012 through 2019.

Postacute Care Services Use and Outcomes Among Traditional Medicare and Medicare Advantage Beneficiaries.

Importance: Better evidence is needed on whether Medicare Advantage (MA) plans can control the use of postacute care services while achieving excellent outcomes.

Objective: To compare self-reported use of postacute care services and outcomes among traditional Medicare (TM) beneficiaries and MA enrollees.

Design, Setting, And Participants: This cohort study used data from the National Health and Aging Trends Study (NHATS) with linked Medicare enrollment data from 2015 to 2017.

Publicly Reported Quality Performance for Dual-eligible Special Needs Plans, 2010-2019.

As enrollment increases in Dual-eligible Special Needs Plans (D-SNPs) that exclusively enroll low-income Medicare beneficiaries with Medicaid coverage, better evidence is needed about quality of care in these managed care plans. Using 2010-2019 publicly reported Healthcare Effectiveness Data and Information Set (HEDIS) measures, we found that median HEDIS performance scores were usually slightly worse for D-SNPs than the overall MA program with some reductions in quality performance gaps between 2010 and 2019. D-SNPs had more incomplete performance reporting than MA contracts, especially for measures focused on clinical conditions.

Comparison of the Pathway to Hospice Enrollment Between Medicare Advantage and Traditional Medicare.

Importance: Older adults in Medicare Advantage (MA) enroll in hospice at higher rates than those in traditional Medicare (TM), but it is unclear whether the pathway of care prior to hospice use differs between MA and TM.

Objective: To examine the site of care prior to hospice enrollment for MA beneficiaries compared with those in TM.

Design, Setting, And Participants: This population-based, retrospective cross-sectional study used Medicare claims data for decedents in calendar years 2011, 2013, 2016, and 2018 who enrolled in hospice in the last 90 days of life.

Association of Race and Income with Incident Diagnosis of Alzheimer's Disease and Related Dementias among Black and White Older Adults.

To investigate how differences in income and education levels may contribute to disparities in incidence of Alzheimer's disease and related dementia (ADRD), we compared ADRD incidence in traditional Medicare claims for 11,132 Black and 7703 White participants aged 65 and over from a predominantly low-income cohort. We examined whether the relationship between ADRD incidence and race varied by income or education. Based on 2015 incident ADRD diagnoses, Black and White participants had unadjusted incidence rates of 26.

Trends in and Factors Contributing to the Slowdown in Medicare Spending Growth, 2007-2018.

Importance: After decades of rapid increase, Medicare per-beneficiary spending growth was historically low in the period leading up to the passage of the Affordable Care Act. In the years immediately following the legislation, Medicare expenditure growth slowed even further.

Objective: To evaluate factors contributing to the slowdown in Medicare per-beneficiary spending growth.

Association of Healthy Lifestyles With Risk of Alzheimer Disease and Related Dementias in Low-Income Black and White Americans.

Background And Objectives: Although the importance of healthy lifestyles for preventing Alzheimer disease and related dementias (ADRD) has been recognized, epidemiologic evidence remains limited for non-White or low-income individuals who bear disproportionate burdens of ADRD. This population-based cohort study aims to investigate associations of lifestyle factors, individually and together, with the risk of ADRD among socioeconomically disadvantaged Americans.

Methods: In the Southern Community Cohort Study, comprising two-thirds self-reported Black and primarily low-income Americans, we identified incident ADRD using claims data among participants enrolled in Medicare for at least 12 consecutive months after age 65 years.

Traditional Medicare Episode-Related Spending on Postacute Care for Dual-Eligible and Medicare-Only Beneficiaries, 2009-2017.

Dual-eligible beneficiaries with Medicare and Medicaid coverage generally have greater utilization and spending levels than Medicare-only beneficiaries on postacute services, raising questions about how strategies to curb postacute spending will affect dual-eligible beneficiaries. We compared trends in postacute spending and use related to inpatient episodes at a population and episode level for dual-eligible and Medicare-only beneficiaries over the years 2009-2017. Although dual-eligible beneficiaries had consistently higher inpatient and postacute service use and spending than Medicare-only populations, both populations experienced similar declines in inpatient and postacute measures over time.

Pathway to Hospice: How Has Place of Care before Hospice Changed with the Growth of Hospice in the United States?

Hospice use among Medicare decedents increased from 21.6% in 2000 to 51.6% in 2019.

Comparing the care experiences of Medicare Advantage beneficiaries with and without Alzheimer's disease and related dementias.

Background: The Medicare Advantage (MA) program is rapidly growing. Limited evidence exists about the care experiences of MA beneficiaries with Alzheimer's Disease and Related Dementia (ADRD). Our objective was to compare care experiences for MA beneficiaries with and without ADRD.

The Association of Health Care System Resources With Lung Cancer Screening Implementation: A Cohort Study.

Background: The Veterans Health Administration issued policy for lung cancer screening resources at eight Veterans Affairs Medical Centers (VAMCs) in a demonstration project (DP) from 2013 through 2015.

Research Question: Do policies that provide resources increase lung cancer screening rates?

Study Design And Methods: Data from eight DP VAMCs (DP group) and 20 comparable VAMCs (comparison group) were divided into before DP (January 2011-June 2013), DP (July 2013-June 2015), and after DP (July 2015-December 2018) periods. Coprimary outcomes were unique veterans screened per 1,000 eligible per month and those with 1-year (9-15 months) follow-up screening.

Traditional Medicare Spending on Inpatient Episodes as Hospitalizations Decline.

Objective: To describe Medicare inpatient episode spending trends between 2009 and 2017 as inpatient use declined among traditional Medicare beneficiaries.

Methods: Inpatient episodes included claims for all traditional Medicare inpatient, outpatient, and Part D services provided during the 30 days prehospitalization, the inpatient stay, and the 90 subsequent days. We describe the mean number of episodes per 1000 beneficiaries, mean episode-related spending per beneficiary, and mean spending per episode for all beneficiaries and for specific populations and types of episodes.

Establishing Medicaid incentives for liberating nursing home patients from ventilators.

Background: Chronic ventilator use in Tennessee nursing homes surged following 2010 increases in respiratory care payment rates. Tennessee's Medicaid program implemented multiple policies between 2014 and 2017 to promote ventilator liberation in 11 nursing homes, including quality reporting, on-site monitoring, and pay-for-performance incentives.

Methods: Using repeated cross-sectional analysis of Medicare and Medicaid nursing home claims (2011-2017), hospital discharge records (2010-2017), and nursing home quality reports (2015-2017), we examined how service use changed as Tennessee implemented policies designed to promote ventilator liberation in nursing homes.

Aligning Medicaid and Medicare Advantage Managed Care Plans for Dual-Eligible Beneficiaries.

To coordinate Medicare and Medicaid benefits, multiple states are creating opportunities for dual-eligible beneficiaries to join Medicare Advantage Dual-Eligible Special Needs Plans (D-SNPs) and Medicaid plans operated by the same insurer. Tennessee implemented this approach by requiring insurers who offered Medicaid plans to also offer a D-SNP by 2015. Tennessee's aligned D-SNP participation increased from 7% to 24% of dual-eligible beneficiaries aged 65 years and above between 2011 and 2017.

Dying with dementia in Medicare Advantage, Accountable Care Organizations, or traditional Medicare.

Background/objective: Medicare Advantage (MA) and Accountable Care Organizations (ACOs) operate under incentives to reduce burdensome and costly care at the end of life. We compared end-of-life care for persons with dementia who are in MA, ACOs, or traditional Medicare (TM).

Design, Setting, And Participants: Retrospective study of decedents with dementia enrolled in MA, attributed to an ACO, or in TM.

Association of Inclusion of Medicare Advantage Patients in Hospitals' Risk-Standardized Readmission Rates, Performance, and Penalty Status.

Importance: The Hospital Readmissions Reduction Program publicly reports and financially penalizes hospitals according to 30-day risk-standardized readmission rates (RSRRs) exclusively among traditional Medicare (TM) beneficiaries but not persons with Medicare Advantage (MA) coverage. Exclusively reporting readmission rates for the TM population may not accurately reflect hospitals' readmission rates for older adults.

Objective: To examine how inclusion of MA patients in hospitals' performance is associated with readmission measures and eligibility for financial penalties.

Mandated Copayment Reductions in Medicare Advantage: Effects on Skilled Nursing Care, Hospitalizations, and Plan Exit.

Objectives: To address concerns that postacute cost-sharing may deter high-need beneficiaries from participating in Medicare Advantage (MA) plans, the Centers for Medicare and Medicaid Services have capped cost-sharing for skilled nursing facility (SNF) services in MA plans since 2011. This study examines whether SNF use, inpatient use, and plan disenrollment changed following stricter regulations in 2015 that required most MA plans to eliminate or substantially reduce cost-sharing for SNF care.

Design: Difference-in-differences retrospective analysis from 2013 to 2016.

National Lung Cancer Screening Utilization Trends in the Veterans Health Administration.

Background: Many Veterans are high risk for lung cancer. Low-dose computed tomography (LDCT) is an effective strategy for lung cancer early detection in a high-risk population. Our objective was to describe and compare annual and geographic utilization trends for LDCT screening in the Veteran's Health Administration (VHA).

Risk adjusting for Medicaid participation in Medicare Advantage.

Objectives: Determining appropriate capitated payments has important access implications for dual-eligible Medicare Advantage (MA) members. In 2017, MA plans began receiving higher capitated payments for beneficiaries with full vs partial Medicaid when payments started being risk adjusted for level of Medicaid benefits instead of any Medicaid participation. This approach could favor MA plans in states with more generous Medicaid programs where more beneficiaries qualify for full Medicaid and thus a higher capitated payment.

Association of daily copayments with use of hospital care among medicare advantage enrollees.

Background: While the traditional Medicare program imposes a deductible for hospital admissions, many Medicare Advantage plans have instituted per-diem copayments for hospital care. Little evidence exists about the effects of changes in cost-sharing for hospital care among the elderly. Changing inpatient benefits from a deductible to a per diem may benefit enrollees with shorter lengths of stay, but adversely affect the out-of-pocket burden for hospitalized enrollees with longer lengths of stay.

Hospital Readmission Rates in Medicare Advantage and Traditional Medicare: A Retrospective Population-Based Analysis.

Background: Medicare's Hospital Readmissions Reduction Program reports risk-standardized readmission rates for traditional Medicare but not Medicare Advantage beneficiaries.

Objective: To compare readmission rates between Medicare Advantage and traditional Medicare.

Design: Retrospective cohort study linking the Medicare Provider Analysis and Review (MedPAR) file with the Healthcare Effectiveness Data and Information Set (HEDIS).
