Drive time to care and retention in HIV care
PURPOSE: Less than 50% of people with HIV (PWH) in the United States are retained in care, a key step along the HIV care continuum. We examined the impact of geographic access to care on retention in care for urban and rural PWH. METHODS: We used Medicaid claims and clinician data (Medicaid Analytic eXtract and MAX Provider Characteristics, 2009-2012) for 13 Southern states plus the District of Columbia. We calculated drive time from the enrollee…
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
Adherence, Switches, and Drug Spending After Angiotensin Receptor Blocker Recalls and Shortages
This cohort study shows that access to alternatives may have mitigated gaps in treatment during the 2018 to 2019 ARB recalls and drug shortages. Potential disparate impacts among certain subgroups highlight the need for policies to mitigate financial and other systematic access barriers to receiving health care during drug shortages
Prescriber-Level Responses to the 2018–2019 Valsartan, Irbesartan, and Losartan Recalls and Drug Shortages
BACKGROUND: Global shortages for 3 angiotensin receptor-II blockers (ARBs)-valsartan, losartan, and irbesartan-occurred in 2018-2019 after recalls due to ingredient impurities. Provider-level responses to the ARB shortages in the United States and spillovers to other antihypertensive classes are unknown. OBJECTIVE: To estimate changes in provider-level prescribing for ARBs and non-ARB antihypertensives up to 18 months after the 2018-2019 recalls …
Racial and Ethnic Disparities in Hospital-Based Care Among Dual Eligibles Who Use Health Centers
Introduction: Health center use may reduce hospital-based care among Medicare-Medicaid dual eligibles, but racial and ethnic disparities in this population have not been widely studied. We examined the extent of racial and ethnic disparities in hospital-based care among duals using health centers and the degree to which disparities occur within or between health centers. Methods: We used 2012-2018 Medicare claims and health center data to model e…
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
High Deductible Health Plans and Use of Free Preventive Services Under the Affordable Care Act
The Affordable Care Act aimed to increase use of preventive services by eliminating cost-sharing to consumers. However, patients may be unaware of this benefit or they may not seek preventive services if they anticipate that the cost of potential diagnostic or treatment services will be too high, both more likely among those in high deductible health plans. We used nationally representative private health insurance claims (100% sample of IBM ® Ma…
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…
Association of Medicaid Expansion With Medicaid Enrollment and Health Care Use Among Older Adults With Low Income and Chronic Condition Limitations
In this cross-sectional study, ACA Medicaid expansion for working-age adults was associated with increased Medicaid enrollment and outpatient health care use among older adults with low income and chronic condition limitations who were dually eligible for Medicare and Medicaid
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 Association Between Area Deprivation Index and Patient-Reported Outcomes in Patients with Advanced Cancer
Background: This analysis describes associations between area deprivation and patient-reported outcomes among patients with advanced cancer. Methods: This is a cross-sectional analysis of baseline data from a multisite primary palliative care intervention trial. Participants were adult patients with advanced cancer. Patient-level area deprivation scores were calculated using the Area Deprivation Index (ADI). Quality of life and symptom burden wer…
Modernizing Medicaid Coverage for Medicare Beneficiaries With Low Income
Medicaid provides supplemental health insurance for 11 million Medicare beneficiaries with low income, who are known as "duals." For these individuals, Medicaid covers Medicare's out-of-pocket costs, including premiums, deductibles, and coinsurance. For some of these individuals, Medicaid also fills in gaps in Medicare coverage by paying for services such as long-term care. 1 Thus, Medicaid provides vital financial protection to low-income Medica…
Welcome Mats and On‐Ramps for Older Adults
For many low-income Medicare beneficiaries, Medicaid provides important supplemental insurance that covers out-of-pocket costs and additional benefits. We examine 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). Previous literature documents so-called "welcome mat" effects in other populations but has not explicitly studied old…
The Impact of Massachusetts Health Reform on Colorectal and Breast Cancer Stage at Diagnosis
BACKGROUND: This study examines the expansion of health insurance coverage in Massachusetts under state health reform as a natural experiment to investigate whether expanded insurance coverage reduced the likelihood of advanced stage colorectal cancer (CRC) and breast cancer (BCA) diagnosis. METHODS: Our study populations include CRC or BCA patients aged 50-64 years observed in the Massachusetts Cancer Registry and Surveillance Epidemiology and E…
Structural barriers to comprehensive, coordinated HIV care
Structural barriers to HIV care are particularly challenging in the US South, which has higher HIV diagnosis rates, poverty, uninsurance, HIV stigma, and rurality, and fewer comprehensive public health programs versus other US regions. Focusing on one structural barrier, we examined geographic accessibility to comprehensive, coordinated HIV care (HIVCCC) in the US South. We integrated publicly available data to study travel time to HIVCCC in 16 S…
Effect of Medicaid Expansions of 2014 on Overall and Early-Stage Cancer Diagnoses
Objectives. To determine whether the 2014 Medicaid expansions facilitated by the Affordable Care Act affected overall and early-stage cancer diagnosis for nonelderly adults. Methods. We used Surveillance, Epidemiology, and End Results Cancer Registry data from 2010 through 2014 to estimate a difference-in-differences model of cancer diagnosis rates, both overall and by stage, comparing changes in county-level diagnosis rates in US states that exp…
Changes in Emergency Department Utilization After Early Medicaid Expansion in California
BACKGROUND: Medicaid expansions aim to improve access to primary care, which could reduce nonemergent (NE) use of the emergency department (ED). In contrast, Medicaid enrollees use the ED more than other groups, including the uninsured. Thus, the expected impact of Medicaid expansion on ED use is unclear. OBJECTIVES: To estimate changes in total and NE ED visits as a result of California's early Medicaid expansion under the Affordable Care Act. I…
The Impact of Integrated Case Management on Health Services Use and Spending Among Nonelderly Adult Medicaid Enrollees
BACKGROUND: Medicaid plans, whose patients often have complex medical, social, and behavioral needs, seek tools to effectively manage enrollees and improve access to quality care while containing costs. OBJECTIVES: The aim of this study is to examine the effects of an integrated case management (ICM) program operated by a Medicaid managed care plan on health service use and spending for nonelderly, nonpregnant adults. RESEARCH DESIGN: We estimate…
Impact of Changes in Medicaid Coverage on Physician Provision of Safety Net Care
Past changes in Medicaid coverage rates are not associated with changes in physician acceptance of new Medicaid patients or provision of charity care, although they are associated with lower acceptance of new uninsured patients, particularly among office-based physicians
The Impact of Maternity Length-of-Stay Mandates on the Labor Market and Insurance Coverage
To understand the effects of insurance regulation on the labor market and insurance coverage, this study uses a difference-in-difference-in-differences analysis to compare five states that passed minimum maternity length-of-stay laws with states that waited until after a federal law was passed. On average, we do not find statistically significant effects on labor market outcomes such as hours of work and wages. However, we find that employees of …
Contraceptive Insurance Mandates and Consistent Contraceptive Use Among Privately Insured Women
INTRODUCTION: Half of the states in the United States mandate that health insurers cover contraceptives. Health care reform includes recommendations to extend these mandates nationally through the essential benefits package. This study evaluates the association of state-level insurance mandates and consistent contraceptive use among privately insured women aged 15-44. STUDY DESIGN: The National Survey of Family Growth (2006-2008) included 2276 pr…
Priority setting in health care
All health care systems face problems of justice and efficiency related to setting priorities for allocating a limited pool of resources to a population. Because many of the central issues are the same in all systems, the United States and other countries can learn from the successes and failures of countries that have explicitly addressed the question of health care priorities.We review explicit priority setting efforts in Norway, Sweden, Israel…
Low-Income Employees’ Choices Regarding Employment Benefits Aimed at Improving the Socioeconomic Determinants of Health
Objectives. Socioeconomic factors are associated with reduced health status in low-income populations. We sought to identify affordable employment benefit packages that might ameliorate these socioeconomic factors and would be consonant with employees’ priorities. Methods. Working in groups (n = 53), low-income employees (n = 408; 62% women, 65% Black) from the Washington, DC, and Baltimore, Md, metropolitan area, participated in a computerized e…
