  • 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.

  • Rural-Urban Differences in Medicaid Utilization
    Nationwide, approximately 1 in 4 rural residents are insured by Medicaid, yet we lack basic understanding of rural-urban differences in Medicaid utilization.

  • Rural/Urban Differences in Postpartum Health Insurance, Healthcare Use, and Health Outcomes
    The purpose of this project is to identify rural/urban differences in health insurance, healthcare use, and health outcomes among postpartum individuals, and to describe policy-relevant implications or strategies to improve insurance coverage, receipt of recommended healthcare, and, ultimately, health outcomes among rural residents who give birth. With a lens towards health equity, all analyses will be stratified by race/ethnicity and income.

  • 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.

  • 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.
