  • Challenges, Successes, and Sustainability of the 2019 Rural Maternity and Obstetrics Management Strategies (RMOMS) Programs
    This mixed-methods study aims to understand awardees' experiences in building and maintaining cohesive networks for Rural Maternity and Obstetrics Management Strategies (RMOMS).
    Research center: Rural and Minority Health Research Center
    Topics: Health disparities and health equity, Health services, Healthcare access, Maternal health, Minority health, Networking and collaboration, Telehealth, Women
  • Changes in Medicare Fee-for-Services Health Care Expenditures in Rural and Urban Communities after Passage of the Affordable Care Act
    This project will assess changes in Medicare per-beneficiary spending across rural and urban counties from 2007 to 2020. It will examine differences in rural versus urban per-beneficiary spending on hospital inpatient, hospital outpatient, physician, and post-acute care after the Affordable Care Act (ACA).
    Research center: Rural and Minority Health Research Center
    Topics: Care management, Chronic diseases and conditions, Health disparities and health equity, Health services, Hospitals and clinics, Public health
  • Disparities in Mental Health Services Access: the Intersectionality of Residence Rurality, Race, and Ethnicity
    In 2021, approximately 8.6 million rural adults faced mental health challenges while millions of rural adolescents battled major depressive episodes. This study examines disparities in mental health services uptake and variation in mental health care settings across racial-ethnic and rural-urban subpopulations before and after the COVID-19 pandemic.
    Research center: Rural and Minority Health Research Center
    Topics: Children and adolescents, Coronavirus Disease 2019 (COVID-19), Health services, Healthcare access, Mental and behavioral health
  • 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.
    Research center: Rural and Minority Health Research Center
    Topics: Children and adolescents, Health disparities and health equity, Medicaid and CHIP, Oral health, Rural statistics and demographics
  • Rural-Urban Differences in Emergency Department Utilization and Costs for Dental Conditions
    Emergency Department (ED) Utilization is a de facto provider for untreated dental issues. Understanding rural-urban differences in ED use for dental conditions in recent years is essential to inform federal, state and community-level dental health initiatives such as preventive dental care, tele-dentistry infrastructure expansion and oral hygiene practices. Ongoing national efforts addressing rural disparities in dental care should target individuals most at risk for missing preventive care and utilizing the ED for dental care.
    Research center: Rural and Minority Health Research Center
    Topics: Emergency medical services (EMS) and trauma, Oral health
  • Rural-Urban Disparities in Mental Health Access and Quality in the United States
    The purpose of this project is to document the recent trends of mental health care access and quality in urban and rural communities and to assess the intersectionality of residence rurality and race/ethnicity on disparities in mental health care access and quality.
    Research center: Rural and Minority Health Research Center
    Topics: Health disparities and health equity, Healthcare access, Mental and behavioral health
  • Spatial Distribution of Pre-Exposure Prophylaxis (PrEP) Need and Care
    The incidence of HIV is disproportionately high in rural areas, but these communities often lack access to evidence-based interventions to prevent new HIV diagnoses such as PrEP. Using Medicaid claims data and the Centers for Medicare & Medicaid Services Provider file, this study will determine geographic disparities (by rurality and region) in the need for PrEP and PrEP availability and identify whether PrEP availability meets the needs across geography.
    Research center: Rural and Minority Health Research Center
    Topics: Health disparities and health equity, Pharmacy and prescription drugs
  • 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.

    Topics: Maternal health, Medicaid and CHIP

  • Availability and Quality of Dialysis in Rural Counties with a High Diabetes Burden
    This project examined the degree to which counties with a high population risk for end stage renal disease, defined by high diabetes prevalence, are served by dialysis providers. It assessed the accessibility and quality of services for end stage renal disease looking for disparities associated with rural residence and racial/ethnic population composition.

    Topics: Diabetes, Health disparities and health equity, Health services, Public health, Quality
  • Availability of Diabetes Self-Management Education in High Need Rural Counties
    This project examined the degree to which counties with a high need for diabetes education, defined by high diabetes prevalence, have such education available. Findings were linked to a related study that examined the availability of dialysis for end stage renal disease, a severe outcome of poorly addressed diabetes.
    Research center: Rural and Minority Health Research Center
    Topics: Diabetes, Health services
  • Cancer Prevention and Control Activities in Rural Hospitals
    This project aimed to understand how rural hospitals perceive and implement evidence-based cancer screening and treatment and related intervention strategies.

  • Examining Rural-Urban Differences in Availability of Hospital Cardiac Testing Services Between 2010-2020
    This project will examine whether the availability of hospital-based cardiac testing services has changed over the past ten years in rural and urban counties and identify the characteristics of counties where service availability has changed.

    Journal Article
    University of Minnesota Rural Health Research Center
    Date: 11/2016
    This study focused on maternity care quality by taking a look at hospitals' policies regarding induced labor and Cesarean deliveries.
  • Why Are Obstetric Units in Rural Hospitals Closing Their Doors?
    Journal Article
    University of Minnesota Rural Health Research Center
    Date: 08/2016
    Analyzes the reasons behind hospital- and county-level factors for rural obstetric unit closures.
  • Factors Associated With High-Risk Rural Women Giving Birth in Non-NICU Hospital Settings
    Journal Article
    University of Minnesota Rural Health Research Center
    Date: 07/2016
    Identifies rick factors for childbirth in facilities without neonatal intensive care unit (NICU) capacities among high-risk rural women. The study found that rural women with preterm birthday and multiple gestation pregnancies were less likely to give birth in a hospital with NICU capacity if no local hospital had this capacity.

    Analyzes the role of certified nurse-midwives (CNMs) in providing maternity care in rural US hospitals and to examine state-level variations on rural CNM practice. CNMs play an important role in the maternity care workforce in rural US hospitals.
  • Ensuring Access to High-Quality Maternity Care in Rural America
    Journal Article
    University of Minnesota Rural Health Research Center
    Date: 05/2016
    Examines the access to high-quality for rural women care during pregnancy and childbirth.

    Journal Article
    University of Minnesota Rural Health Research Center
