Current Projects

  • A Closer Examination of Rural Hospital Bypass
    This project will estimate the rural hospital bypass rate using all-payer claims data for a set of states and compare patients based on the inpatient treatments and procedures received relative to those routinely provided by rural facilities.

    Topics: Critical Access Hospitals (CAHs), Health reform, Health services, Healthcare access, Hospitals and clinics, Medicaid and CHIP, Medicare, Medicare Advantage (MA), Minority health, Private health insurance, Uninsured and underinsured
  • Changes in Access to Care During the Public Health Emergency: Examining Rural-Urban Disparities by Insurance Type
    Using the Behavioral Risk Factor Surveillance System data, this study will compare key access to care indicators among adult beneficiaries residing in rural and urban areas before and after the Public Health Emergency by types of health insurance. Researchers will explore state-level policy variations, such as the Affordable Care Act Medicaid expansion and COVID-19-related Medicaid coverage for uninsured adults.

  • Changes in Rural Health Insurance Coverage, 2020-2023
    This project uses secondary data sources to characterize changes in health insurance coverage during the public health emergency (2020-2023) for rural and urban people according to demographic, employment, and geographic characteristics, and to describe how changes in federal policies impacted coverage. Researchers also assess the potential impact of maintaining more robust marketplace subsidies on rural and urban coverage rates once the "unwinding" of continuous Medicaid enrollment is complete.

  • Hierarchical Condition Category (HCC) Risk Scores: Designed to Predict Future Cost and Health Care Resource Use – Do They Also Accurately Reflect Differences in Health Status between Rural and Urban Beneficiaries?
    This CMS Hierarchical Condition Category (CMS-HCC) risk score study will investigate differences in underlying health between rural and urban populations using recent data and analyze which factors drive observed differences.

  • Oral Healthcare Utilization and Outcomes of Rural and Urban Medicaid-Insured Children in the United States
    Using nationally representative Medicaid claims data, this project will determine rural-urban differences in the prevalence of early childhood caries, preventative dental visits, and restorative dental visits.

  • Postpartum Morbidity and Mortality and Health Care Utilization in Rural vs. Urban Communities
    Using 2006-2018 data from the National Health Interview Survey linked to the National Death Index through 2019, this project will examine postpartum mortality among rural and urban residents. We will also evaluate differences in health, health care utilization, and barriers to care across rural and urban communities.

  • Public Health Insurance Coverage Among Rural and Urban Children
    Medicaid and the Children's Health Insurance Program (CHIP) are important sources of health insurance coverage for rural children, yet analyses have shown a decline in overall U.S. coverage in recent years. This study will use the American Communities Survey to examine rates of Medicaid/CHIP coverage among rural versus urban children and whether these have changed over time.

    Topics: Children and adolescents, Medicaid and CHIP
  • Rural and Urban Sepsis Outcomes as a Measure of Health Care Quality: A Nationwide Comparative Analysis Using HCUP Data
    This study examines differences in sepsis prevalence, outcomes, costs, and treatment between rural and urban hospitals using the HCUP Nationwide Readmissions Database. It aims to inform policies related to access to timely, high-quality sepsis care and identify strategies to enhance healthcare outcomes across diverse hospital settings.

  • Screening, Brief Intervention and Referral to Treatment (SBIRT) Penetration in Rural vs. Urban Healthcare Settings in the U.S.
    This study will include an analysis of 2018/2019 Medicare, Medicaid and Commercial claims to compare the penetration of Screening, Brief Intervention and Referral to Treatment (SBIRT) and its different components in rural compared to urban healthcare settings. Within the overarching analysis, the study team will examine the type of interventions conducted within the SBIRT framework stratified by provider type, healthcare setting, and rural and urban provider ZIP codes. Findings will be analyzed within the context of county-level substance use rates, historical enactment of state SBIRT billing codes, overdoses, and alcohol poisoning-based hospital admissions contrasting trends in SBIRT administration with a proxy for community need.

  • State-Level Medicaid Bundled Payments and Rural Perinatal Care
    The impacts of state-level Medicaid bundled payment models will depend on many factors, such as maternity care facility structure, scope of services, and local patient bypassing behaviors during prenatal, intrapartum, and postpartum periods. For rural providers who often offer prenatal and postpartum care but not labor and delivery services, these bundled payments may impose additional financial and logistical challenges.

  • Treatment, Provider, and Cost Differences for Rural and Urban Patients with Opioid Use Disorder and Medicaid Insurance Across the U.S.
    This project will analyze Medicaid claims data to compare the treatment that rural and urban patients with opioid use disorder receive, documenting the workforce providing care, the distance that patients travel to receive care, and the cost of care. Findings from this study can be used to improve policies regarding opioid use disorder treatment.

  • Updating and Exploring the Burden of Potentially Avoidable Emergency Department Visits in Rural U.S. Communities
    This project will update the Federal Office of Rural Health Policy's research portfolio on potentially avoidable emergency department (ED) visits among rural residents across the U.S., particularly as they relate to ambulatory care sensitive conditions (ACSCs). Data on ACSC-related ED visits will be drawn from the State Emergency Department Databases, and findings will be stratified by census region, patient's place along the urban-rural continuum, and by race/ethnicity.
