Development and Evolution of a Statewide Outpatient Consultation Service: Leveraging Telemedicine to Improve Access to Specialty Care.

Despite a robust health care system in the United States, many Americans experience health care disparities as a result of poor access to medical care. Academic medicine plays an important role in addressing health care disparities by providing primary and specialty care for the poor and uninsured. In South Carolina, 43 of its 46 counties are designated as fully or partially Medically Underserved Areas (MUAs), defined as areas with a shortage of medical providers, high infant mortality, and either high elderly population or high poverty rates. To address these health care disparities, an academic medical center in South Carolina created a hub-and-spoke specialty care model using telemedicine in partnership with primary care providers across community settings. Initial private foundation grant funding enabled the development and dissemination of technology to provide remote teleconsultations by physicians at the academic medical center (hub) to patients in their primary care offices (spoke). This model, now supported by recurring state funding and professional billing, provides much-needed services, including psychiatry, nutrition counseling, and various surgical and medical subspecialties, to rural and underserved populations in the state. This manuscript provides a narrative review of the development of this statewide telemedicine service, with an emphasis on identification of stakeholders, technology issues, barriers to implementation, and future directions.
