Accuracy of Cancer Registry Primary Payer Information and Implications for Policy Research
BACKGROUND: Cancer registry-based "primary payer at diagnosis" (PPDx) data are commonly used to evaluate the effect of insurance on cancer care outcomes, yet little is known about how well they capture Medicaid or Medicare enrollment. METHODS: We linked the National Cancer Institute's Surveillance, Epidemiology, and End Results registry data to monthly Centers for Medicare and Medicaid Services (CMS) Medicaid and Medicare enrollment records, stat…
Changes in Health Insurance Coverage Associated With the Affordable Care Act Among Adults With and Without a Cancer History
BACKGROUND: The Affordable Care Act (ACA) improved health care coverage accessibility by expanding Medicaid eligibility, creating insurance Marketplaces, and subsidizing premiums. We examine coverage changes associated with ACA implementation, comparing adults with and without a cancer history. METHODS: We included nonelderly adults from the 2012 to 2015 National Health Interview Survey. Using information on state Medicaid policies (2013), expans…
The ACA’s Zero Cost-Sharing Mandate and Trends in Out-of-Pocket Expenditures on Well-Child and Screening Mammography Visits
BACKGROUND: Starting in September of 2010, the Patient Protection and Affordable Care Act required most health insurance policies to cover evidence-based preventive care with no cost-sharing (no copays, coinsurance, or deductibles). It is unknown, however, whether declines in out-of-pocket costs for preventive services are large enough to prompt increases in utilization, the ultimate goal of the policy. METHODS: In this study, we use a nationally…
Validation of Disability Status, a Claims-based Measure of Functional Status for Cancer Treatment and Outcomes Studies
BACKGROUND: In prior research, we developed a claims-based prediction model for poor patient disability status (DS), a proxy measure for performance status, commonly used by oncologists to summarize patient functional status and assess ability of a patient to tolerate aggressive treatment. In this study, we implemented and validated the DS measure in 4 cohorts of cancer patients: early and advanced non-small cell lung cancers (NSCLC), stage IV es…
Use and Spending on Antineoplastic Therapy for Medicare Beneficiaries With Cancer
BACKGROUND: Oral antineoplastic drugs, not generally covered by Medicare Part B, have assumed an increasingly important role in cancer treatment. OBJECTIVE: We examined use and spending on infused/injected (Part B covered) and non-Part B antineoplastic agents in a Medicare beneficiary population with cancer, and the effect of supplemental insurance. RESEARCH DESIGN: This retrospective, observational study used pooled 1997-2007 data from the Medic…
Eligibility and Take-up of the Medicare Part D Low-Income Subsidy
There is concern about poor take-up of the Medicare Part D Low-Income Subsidy (LIS), but uncertainty in published estimates. The Medicare Current Beneficiary Survey (MCBS), which contains Medicare LIS enrollment records and extensive survey data on individual beneficiary characteristics, would appear an ideal resource for evaluating LIS take-up. However, use of the MCBS to identify eligible beneficiaries is limited due to underreporting of income…
Impact of Part D Low-income Subsidies on Medication Patterns for Medicare Beneficiaries With Diabetes
BACKGROUND: It is not known whether low-income subsidies (LIS) under Medicare Part D help beneficiaries overcome impediments to medication use associated with poor socioeconomic status and high disease burden. OBJECTIVES: To compare Medicare beneficiaries with LIS and Medicaid (duals), LIS without dual eligibility, and non-LIS recipients on use of medications recommended in diabetes treatment. RESEARCH DESIGN: Fixed-effect comparisons among benef…
Medication Use and Adherence Among Elderly Medicare Beneficiaries With Diabetes Enrolled in Part D and Retiree Health Plans
BACKGROUND: Employer-based retiree drug benefits have long been viewed as the gold standard of drug coverage for elderly Medicare beneficiaries. The question for policy makers is whether beneficiaries enrolled in Part D plans exhibit drug utilization patterns comparable with those seen in retiree plans. OBJECTIVE: To compare utilization patterns for antidiabetic agents, renin-angiotensin-aldosterone system inhibitors, and antihyperlipidemics by e…
Trends in Disparities in Receipt of Adjuvant Therapy for Elderly Stage III Colon Cancer Patients
BACKGROUND: Race disparities in adjuvant chemotherapy for stage III colon cancer patients have been documented, and medical oncologist evaluation is a critical step in the treatment process. Recent healthcare system and environmental changes may have reduced treatment gaps. OBJECTIVES: To examine differential rates of oncologist evaluation and conditional treatment, by race, and to determine whether changing evaluation and treatment patterns redu…
How Children with Special Health Care Needs Affect the Employment Decisions of Low-Income Parents
The Effect of Parents' Insurance Coverage on Access to Care for Low-Income Children
This study examines the effects of having an uninsured parent on access to health care for low-income children. Using data from the 1999 National Survey of America's Families, we find that having an uninsured parent decreases the likelihood that a child will have any medical provider visit by 6.5 percentage points, and decreases the likelihood of a well-child visit by 6.7 percentage points. Estimates for low-income children who have insurance but…
Health Insurance Costs and Early Retirement Decisions
The loss of health insurance may be an important component of the cost of retirement, especially for workers without retiree health insurance coverage. The authors find that insurance costs significantly reduce retirement rates for full-time wage and salary workers ages 51 to 61. Simulations suggest that a $1,000 increase in the net present value of health insurance premium costs reduces the probability of early retirement by 0.17 percentage poin…
Determinants of Public and Private Insurance Enrollment Among Medicaid-Eligible Children
BACKGROUND: Many Medicaid-eligible children are not enrolled in Medicaid and are not covered by private insurance. Reducing persistent lack of insurance for children requires a better understanding of why Medicaid-eligible children do not participate. RESEARCH QUESTIONS: Does the availability of free or low-cost medical services substitute for Medicaid or private insurance enrollment among Medicaid-eligible children? Does the availability and aff…
