Development of the Health Disparities Prevention Quality Index for Medicare Accountable Care Organizations
Background: Value-based care aims to improve quality and reduce costs, yet racial and ethnic disparities in health outcomes persist, including within Medicare Shared Savings Program accountable care organizations (ACOs). This study introduces the Health Disparities Prevention Quality Index (HDPQI), a novel measure designed to evaluate disparities in preventable hospital admissions, using heart failure (HF) as a case study. Methods: We analyzed ad…
Hospitalization and Credit Scores Among Medicaid Beneficiaries in Louisiana
This case-control study evaluates the impact of a hospitalization on credit scores for Medicaid beneficiaries in Louisiana stratified by sex, race, and ethnicity
Impacts of State Covid-19 Vaccine Mandates for Health Care Workers on Health Sector Employment in the United States
Objectives. To assess the impact of state COVID-19 vaccine mandates for health care workers (HCWs) on health sector employment in the United States. Methods. Using monthly state-level employment data from the Quarterly Census of Employment and Wages between January and October 2021, we employed a partially pooled synthetic control method that accounted for staggered mandate adoption and heterogeneous treatment effects. We conducted analyses separ…
Financial Health Among Louisiana Medicaid Enrollees
This cross-sectional study compares average credit scores and unpaid medical and nonmedical debts in collections among Black, Hispanic, and White adults with Medicaid coverage
Non‐monetary obstacles to medical care
We use changes to Medicaid immediate postpartum policy to test whether non‐monetary costs are meaningful obstacles to health care. Medicaid in several states currently covers long‐acting reversible contraceptives (LARCs, including IUDs and implants) immediately following delivery of a child, eliminating much of the time‐cost and stress associated with obtaining a LARC. Postpartum LARCs can reduce unintended and short‐interval pregnancies, which a…
Disparities in Telemedicine Use Among Louisiana Medicaid Beneficiaries During the Covid-19 Pandemic
BACKGROUND: The COVID-19 pandemic led to an increased reliance on telemedicine. Whether this exacerbated existing disparities within vulnerable populations is not yet known. OBJECTIVES: Characterize changes in outpatient telemedicine evaluation and management (E&M) services for Louisiana Medicaid beneficiaries by race, ethnicity, and rurality during the COVID-19 pandemic. RESEARCH DESIGN: Interrupted time series regression models estimated pre-CO…
Opioid prescribing restrictions and opioid use among the Louisiana Medicaid population
Louisiana Medicaid Expansion and Pent-Up Demand
BACKGROUND: Nearly half a million newly eligible people enrolled in Louisiana Medicaid following its expansion. OBJECTIVES: To evaluate postexpansion utilization trends in Louisiana Medicaid. RESEARCH DESIGN: We plotted utilization trends for expansion and traditional Medicaid beneficiaries and conducted regression analyses to evaluate differences in monthly trends for over 2 years following expansion. SUBJECTS: We restricted our sample to a bala…

The long-run effects of adolescent athletic participation on women’s health
Covid-19 eviction moratoriums and eviction filings
Securing stable housing to prevent the spread of infection during the COVID-19 pandemic remains a concern among policymakers in the US. In this article, we provide a descriptive analysis of the association between COVID-19-related eviction moratoriums and eviction filings in New Orleans, Louisiana. Beginning in March 2020, four separate moratoriums were implemented at the local, state, and federal levels that sought to restrict eviction filings i…
Medicaid Expansion and Medical Debt
Objectives. To identify the association between Medicaid eligibility expansion and medical debt. Methods. We used difference-in-differences design to compare changes in medical debt for those gaining coverage through Louisiana’s Medicaid expansion with those in nonexpansion states. We matched individuals gaining Medicaid coverage because of Louisiana’s Medicaid expansion (n = 196 556) to credit report data on medical debt and compared them with r…
Social Health Insurance and the Use of Formal and Informal Care in Developing Countries
This paper studies the relationship between the use of formal and informal health care in a developing country setting by examining the introduction of a social health insurance scheme in Ghana. We estimate the effects of gaining coverage on changes in care seeking behaviour and show how these effects differ by age and wealth status. District-level differences in the implementation of the insurance scheme provide exogenous variation in access to …
