The Impact of Telehealth Expansion on Health Care Utilization, Access, and Outcomes During the Pandemic: A Systematic Review

Introduction: The COVID-19 pandemic brought unprecedented change to the health care industry, including a large and rapid shift to providing care through telehealth technologies. Although the expansion of telehealth services was successful in continuing to provide patients with care while preventing the spread of disease, it is less clear how patient sociodemographic characteristics influenced telehealth use during this time. This study aims to systematically review the published literature on demographic differences in telehealth access, utilization, and health outcomes among a variety of adult patient types in the United States. Methods: Litcovid, PubMed, Web of Science, and MEDLINE databases were searched, resulting in a final sample of n = 32 studies. Results: Results found that studies could be categorized as addressing at least one of eight different areas of inquiry: sociodemographic differences in telehealth use (1) during and (2) before the pandemic, telehealth use versus nonuse (3) during and (4) before the pandemic, (5) telehealth modality, (6) satisfaction with telehealth, (7) outcomes associated with telehealth use, and (8) perceived or actual access to telehealth services. Discussion: Findings are robust across included studies with respect to racial, age, and socioeconomic differences in telehealth utilization and health outcomes, reflecting sociodemographic differences in health care access, utilization, and outcomes more broadly that persist despite this expansion of telehealth services owing to COVID-19. Additional findings across studies are summarized and areas for future research are discussed.
