High-Cost Cancer Drug Use in Medicare Advantage and Traditional Medicare
In this cohort study, high-cost drugs were more commonly prescribed among patients enrolled in TM and diagnosed with CRC. A similar pattern was not observed for patients with NSCLC, perhaps because clinical evidence suggests survival benefits to be associated only with certain drugs, all of which are expensive. Nonetheless, MA was modestly associated with reduced high-cost drug utilization and may reduce overall treatment costs
Healthcare utilization patterns before and after a long Covid diagnosis
Long COVID patients increased outpatient healthcare utilization following a diagnosis, switching from acute care settings. The change in service settings among this population suggests that diagnosis could lead to better patient management. Healthcare utilization among these patients is high, underscoring the need to understand the Long COVID burden on healthcare systems with population-level data
Medicare-Covered Services Near the End of Life in Medicare Advantage vs Traditional Medicare
MA enrollment was associated with lower rates of potentially burdensome and facility-based care near the EOL. Greater use of home-based care may improve quality of care but may also leave patients without adequate assistance after hospitalization
The Effect of Medicare Annual Wellness Visits on Breast Cancer Screening and Diagnosis
OBJECTIVE: The Medicare Annual Wellness Visit (AWV)-a prevention-focused annual check-up-has been available to beneficiaries with Part B coverage since 2011. The objective of this study was to estimate the effect of Medicare AWVs on breast cancer screening and diagnosis. DATA SOURCES AND STUDY SETTING: The National Cancer Institute's Surveillance, Epidemiology, and End Results cancer registry data linked to Medicare claims (SEER-Medicare), HRSA's…
Treatment Disparities in Radiation and Hormone Therapy Among Women Covered by Medicaid vs Private Insurance in Cancer Registry and Claims Data
Among women with breast cancer covered by Medicaid vs private insurance, cancer treatment disparities may be overestimated if based solely on cancer registry data
Building Data Infrastructure for Disease-Focused Health Economics Research
BACKGROUND: Data infrastructure for cancer research is centered on registries that are often augmented with payer or hospital discharge databases, but these linkages are limited. A recent alternative in some states is to augment registry data with All-Payer Claims Databases (APCDs). These linkages capture patient-centered economic outcomes, including those driven by insurance and influence health equity, and can serve as a prototype for health ec…
Capitalizing on Central Registries for Expanded Cancer Surveillance and Research
BACKGROUND: State central cancer registries are an essential component of cancer surveillance and research that can be enriched through linkages to other databases. This study identified and described state central registry linkages to external data sources and assessed the potential for a more comprehensive data infrastructure with registries at its core. METHODS: We identified peer-reviewed papers describing linkages to state central cancer reg…
The Effect of the Affordable Care Act on Women’s Postpartum Insurance and Depression in 5 States That Did Not Expand Medicaid, 2012–2015
BACKGROUND: Before the Affordable Care Act (ACA), most women who gained pregnancy-related Medicaid were not eligible for Medicaid as parents postpartum. The ACA aimed to expand health insurance coverage, in part, by expanding Medicaid; introducing mandates; reforming regulations; and establishing exchanges with federal subsidies. Federal subsidies offer a means to coverage for individuals with income at 100%-400% of the federal poverty level who …
The Impact of Medicare Health Insurance Coverage on Lung Cancer Screening
BACKGROUND: Annual lung cancer screening via low-dose computed tomography can reduce lung cancer mortality among high-risk adults by 20%; however, screening take-up remains low. Inadequate insurance coverage or access to care may be a barrier to screening. OBJECTIVE: The objective of this study was to estimate the effect of nearly universal access to Medicare coverage on annual lung cancer screening. RESEARCH DESIGN: A regression discontinuity de…
Persistent Disparities in Medicare’s Annual Wellness Visit Utilization
INTRODUCTION: The Medicare Annual Wellness Visit (AWV) is a preventive care visit introduced in 2011 as part of the Affordable Care Act provided without cost to beneficiaries. The AWV is associated with higher preventive services utilization. Although AWV utilization increased during 2011-2013, utilization was lower among ethnoracial minority beneficiaries who may benefit the most. OBJECTIVES: To determine if AWV utilization disparities have pers…
Trends and Racial Differences in First Hospitalization for Stroke and 30-Day Mortality in the US Medicare Population From 1988 to 2013
PURPOSE: The main purpose of this study was to determine whether there were temporal differences in the rates of first stroke hospitalizations and 30-day mortality after stroke between black and white Medicare enrollees. METHODS: We used a 20% sample of Medicare beneficiaries aged 65 years or older and described the annual rate of first hospitalization for ischemic and hemorrhagic strokes from years 1988 to 2013, as well as 30-day mortality after…
Ethnoracial Disparities in Medicare Annual Wellness Visit Utilization
INTRODUCTION: In 2011, Medicare began offering annual preventive care visits (annual wellness visit; AWV) to beneficiaries at no charge. Providing free preventive care supports primary and secondary prevention of chronic disease and may reduce ethnoracial disparities in health outcomes. OBJECTIVES: To estimate AWV utilization trends by ethnoracial group in a nationally representative sample of the Medicare population. RESEARCH DESIGN: We estimate…
