  • Chartbook: Dental Health and Access to Care among Rural Children: A National and State Portrait (Full Report)
    South Carolina Rural Health Research Center
    Date: 03/2008
    Although children's dental health in the U.S. has improved over recent decades, a subset of children continues to suffer dental disease severe enough to constitute a public health problem. This Chartbook examines dental health status, use of preventive services, and dental insurance among rural and urban children. The Chartbook provides information specific to rural children, and in particular rural minority children, not available in similar detail from other sources. This information can be used at the state level for program planning and assessment.
  • Dental Sealant Utilization Among Rural and Urban Children
    South Carolina Rural Health Research Center
    Date: 03/2013
    Examines the proportion of rural children who have received dental sealants applied to the surface of their teeth to prevent or delay the development of dental decay.
  • Dialysis Availability in Rural America
    South Carolina Rural Health Research Center
    Date: 01/2013

    Explores the availability of dialysis services in rural America including the prevalence of dialysis use across urban and rural counties, travel distance for services, and dialysis quality outcomes.

    Include the following:

    • The prevalence of dialysis use did not differ across urban versus rural counties.
    • Rural residents travel further for dialysis services.
    • Fewer expanded dialysis services (peritoneal dialysis, home hemodialysis training, and after-hours availability) were offered in rural areas.
    • Dialysis quality outcomes were similar across rural and urban end stage renal disease facilities.
  • Free Clinics in the Rural Safety Net, 2014
    Policy Brief
    South Carolina Rural Health Research Center
    Date: 09/2015

    This brief explores two issues. First, we examine where free clinics are located and describe their availability in rural counties across all 50 states. This information was derived from clinic listings on the website of the National Association of Free and Charitable Clinics (NAFC). Second, through telephone interviews with leadership at 14 of the 21 state free clinic associations, we explore issues facing free clinics during the current period of change. Issues examined include perceived changes in demand subsequent to implementation of the Affordable Care Act and different funding models and strategies used by free clinics.
