Impact of Medicaid Managed Care, Race/Ethnicity, and Rural/Urban Residence on Avoidable Maternity Complications: A Five-State Multi-level Analysis
This project will examine differences in access to care for pregnant women enrolled in Medicaid Managed Care (MMC) and Medicaid fee-for-service, and examine differences in the impact of MMC on access among rural and minority persons.
Research center: South Carolina Rural Health Research Center
Topics: Maternal and child health, Medicaid and S-CHIP, Minority health, Women
Mode of Travel and Actual Distance Traveled for Medical or Dental Care by Rural Residents
This project examined the influence of race and rural isolation on distance traveled to receive medical or dental care, and how the potential interaction of these factors might exacerbate disparities in access to care.

  • Assessment Of Barriers To The Delivery Of Medicare Reimbursed Diabetes Self-Management Education In Rural Areas
    South Carolina Rural Health Research Center
    Date: 09/2004
    Explores the barriers that rural practitioners face in providing diabetes education services to Medicare beneficiaries. Survey results from a random sample of ADA-recognized diabetes education facilities indicated that insufficient Medicare reimbursement, staffing, institutional support as well as the ADA recognition process all constituted barriers to diabetes self-management education in rural areas.
  • Barriers Associated With the Delivery of Medicare Reimbursed Diabetes Self-Management Education
    South Carolina Rural Health Research Center
    Date: 11/2005
    Explores the barriers that practitioners face in providing diabetes self-management education to Medicare beneficiaries. Barriers identified for rural providers include costs, the shortage of designated specialists, fewer resources, amount of Medicare reimbursement, transportation and more.
  • Community Health Center and Rural Health Clinic Presence Associated with Lower County-Level Hospitalization Rates for Ambulatory Care Sensitive Conditions (Full Report)
    South Carolina Rural Health Research Center
    Date: 08/2009
    Examines the effect of the presence of a Federally Qualified Community Health Center (CHC) or Rural Health Clinic (RHC) within a county on population rates of hospitalization for ambulatory care sensitive (ACS) conditions, using data from eight states.
  • Delivery Complications Associated With Prenatal Care Access for Medicaid-Insured Mothers in Rural and Urban Hospitals
    South Carolina Rural Health Research Center
    Date: 2005
    Examined access to healthcare during pregnancy for mothers insured by Medicaid as well as the risks of potentially avoidable maternity complications among rural and urban hospital deliveries for groups of mothers defined by race or ethnicity.
  • Depression in Rural Populations: Prevalence, Effects on Life Quality, And Treatment-Seeking Behavior
    South Carolina Rural Health Research Center
    Date: 05/2005
    Using the National Health Interview Survey and the NHIS-administered depression scale from the Comprehensive International Diagnostic Interview to explore depression among rural versus urban residents, the authors found that the prevalence of major depression was significantly higher among rural (6.11%) than among urban (5.16%) populations. However, nearly all individuals scoring positive for depression reported that their symptoms interfered with their life or activities (46.67% rural, 44.25% urban). Persons without any health insurance were less likely to have communicated with a physician than were the privately or publicly insured. Additionally, the likelihood that an individual with depression would have communicated with a practitioner rose as the person's self reported health declined.
  • Disability Burdens Among Older Americans Associated with Gender and Race/Ethnicity in Rural and Urban Areas
    South Carolina Rural Health Research Center
    Date: 09/2005
    No prior research has investigated differences in disability-free and disabled life expectancy associated with rural or urban residence. This report addresses this gap, and identifies differences in healthy life expectancy that may signal important policy needs. The authors examined total life expectancy, disability-free life expectancy, and disabled life expectancy, comparing people in rural and urban areas. These expectancy measures for subgroups of rural and urban areas were compared, distinguished by sex, race (white and African American) and educational attainment. The authors found that among a cohort of Americans aged 65 to 69 in 1982, in seven of the eight subgroups, individuals in rural areas lived longer lives than those in urban areas. Rural as compared to urban people lived (a) more disability-free years, (b) more disabled years, and (c) a notably greater percentage of their lives with a disability. There were striking differences among the high and low education groups, with individuals with more education living substantially longer, less disabled lives. Women lived longer, more disabled lives than men. For most subgroups, African Americans lived shorter, more disabled lives than whites.
  • Impact Of Medicaid Managed Care, Race/Ethnicity, and Rural/Urban Residence On Potentially Avoidable Maternity Complications: A Five-State Multi-Level Analysis
    South Carolina Rural Health Research Center
    Date: 12/2004
    Complications of pregnancy affect the lives of many women and infants. This study examines pregnancy-related complications using Potentially Avoidable Maternity Complications (PAMCs) as an indicator of access. Findings include: 1) Mothers delivering in rural hospitals had lower PAMC risks than those with urban deliveries.; 2) In rural hospitals, African American women had greater PAMC risks than white women.; and 3) In urban hospitals, adjusted PAMC risks were substantially lower for Hispanics and Asians than for whites.
  • Mode of Travel and Actual Distance Traveled For Medical or Dental Care By Rural and Urban Residents
    South Carolina Rural Health Research Center
    Date: 05/2006
    Discusses the cost and difficulty associated with travel for medical or dental care, which may serve as a barrier for rural populations.
  • More May Be Better: Evidence of a Negative Relationship Between Physician Supply and Hospitalization for Ambulatory Care Sensitive Conditions
    South Carolina Rural Health Research Center
    Date: 2005
    The authors conducted an empirical test of the relationship between physician supply and hospitalization for ambulatory care sensitive conditions (ACSH). Principal findings showed that in the urban models for ages 0-17 physician supply has the largest negative adjusted relationship with ACSH. For ages 18-39 and 40-64, physician supply has the second largest negative adjusted relationship with ACSH. Physician supply was not associated with ACSH in rural areas. The authors conclude that physician supply is positively associated with the overall performance of the primary health care system in a large sample of urban counties of the United States.
  • Racial and Ethnic Disparities in Potentially Avoidable Delivery Complications Among Pregnant Medicaid Beneficiaries in South Carolina
    South Carolina Rural Health Research Center
    Date: 2006
    Within groups defined by race or ethnicity, unadjusted rates for potentially avoidable maternity complications did not differ significantly by hospital location. Potentially avoidable maternity complications in rural hospitals, African Americans had higher risk for complications than did non-Hispanic whites.
  • Rural-Urban Differences in Depression Prevalence: Implications for Family Medicine
    South Carolina Rural Health Research Center
    Date: 10/2006
    Examined the prevalence of depression in rural vs. urban areas. An estimated 2.6 million rural adults suffer from depression. The unadjusted prevalence of depression was significantly higher among rural than urban populations. After adjusting for rural/urban population characteristics, the odds of depression did not differ by residence.
