Insurance Coverage and Provision of Opioid Disorder Treatment: Evidence From Medicare
Older adult opioid overdose deaths have increased over the past two decades in the United States. Methadone, one of three medications approved for opioid use disorder (OUD) treatment, was not covered by Medicare—the primary insurer of Americans 65 years and older—for OUD until 2020. We study the response of opioid treatment programs (OTPs), the only healthcare providers that can dispense methadone for the treatment of OUD in the United States, to…
Trends in Access to Medications for Opioid Use Disorder
This cross-sectional study of Medicaid unwinding and filled buprenorphine prescriptions found that although shifts to commercial and self-pay sources mitigated some losses, rising self-pay reliance poses affordability barriers that threaten treatment continuity. Addressing access disparities is critical amid persistently high US overdose rates
Adoption of Artificial Intelligence in the Health Care Sector
This cross-sectional study examines artificial intelligence use in health care and other industries according to US firms participating in the 2023 to 2025 Business Trends and Outlook Survey
Trends in Abortion- and Contraception-Related Internet Searches After the US Supreme Court Overturned Constitutional Abortion Rights: How Much Do State Laws Matter?
The findings of this retrospective cross-sectional study suggest that changes in internet searching for terms related to reproductive health care can capture immediate population-level changes in information-seeking behavior regarding reproductive health care access. These data are critical for shaping health policy discussions
US Health Care Workforce Changes During the First and Second Years of the Covid-19 Pandemic
This article quantifies changes in employment and average wages of employees of 6 key health care organizations during the COVID-19 pandemic
The Opioid Crisis, Health, Healthcare, and Crime: A Review of Quasi-Experimental Economic Studies
We review quasi-experimental studies that examine the relationship of opioids to health, healthcare, and crime in the U.S. Our findings align with the general perception that the opioid crisis has negatively impacted health and increased healthcare costs; we find limited evidence that appropriate opioid use enhances work capacity or carries other benefits. Extant studies suggest that opioids also increase crime, although the link is not as strong…
Covid-19 booster uptake among US adults: Assessing the impact of vaccine attributes, incentives, and context in a choice-based experiment
US Trends in Covid-19–Associated Hospitalization and Mortality Rates Before and After Reopening Economies
In this cross-sectional study conducted over a 3.5-month period across 47 US states, data on the association of hospitalizations and mortality with state reopening policies may provide input to state projections of the pandemic as policy makers continue to balance public health protections with sustaining economic activity
The Great Unequalizer: Initial Health Effects of Covid-19 in the United States
We measure inequities from the COVID-19 pandemic on mortality and hospitalizations in the United States during the early months of the outbreak. We discuss challenges in measuring health outcomes and health inequality, some of which are specific to COVID-19 and others that complicate attribution during most large health shocks. As in past epidemics, preexisting biological and social vulnerabilities profoundly influenced the distribution of diseas…
Determinants of Disparities in Covid-19 Job Losses
We make several contributions to understanding the socio-demographic divide in early labor market responses to the U.S. COVID-19 epidemic and its policies, benchmarked against two previous recessions.First, monthly Current Population Survey (CPS) data show greater declines in employment in April and May 2020 (relative to February) for Hispanics, younger workers, and those with high school degrees and some college.Between April and May, all the de…

Designing Difference in Difference Studies: Best Practices for Public Health Policy Research
The difference in difference (DID) design is a quasi-experimental research design that researchers often use to study causal relationships in public health settings where randomized controlled trials (RCTs) are infeasible or unethical. However, causal inference poses many challenges in DID designs. In this article, we review key features of DID designs with an emphasis on public health policy research. Contemporary researchers should take an acti…
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…
Did the Affordable Care Act Young Adult Provision Affect Labor Market Outcomes? Analysis Using Tax Data
Using a data set of US tax records spanning 2008 to 2013, the authors study the impact of the Affordable Care Act (ACA) young adult dependent coverage requirement on labor market-related outcomes, including measures of employment status, job characteristics, and postsecondary education. They find that the ACA provision did not result in substantial changes in labor market outcomes. Results show that employment and self-employment are not statisti…

Medicaid Expansion Under the Affordable Care Act and Insurance Coverage in Rural and Urban Areas
PURPOSE: To analyze the differential rural-urban impacts of the Affordable Care Act Medicaid expansion on low-income childless adults' health insurance coverage. METHODS: Using data from the American Community Survey years 2011-2015, we conducted a difference-in-differences regression analysis to test for changes in the probability of low-income childless adults having insurance in states that expanded Medicaid versus states that did not expand, …

The Effect of SCHIP Expansions on Health Insurance Decisions by Employers
This study uses repeated cross-sectional data from the Medical Expenditure Panel Survey-Insurance Component (MEPS-IC), a large nationally representative survey of establishments, to investigate the effect of the State Children's Health Insurance Program (SCHIP) on health insurance decisions by employers. The data span the years 1997 to 2001, the period when states were implementing SCHIP. We exploit cross-state variation in the timing of SCHIP im…
