Quantifying COVID-19’s Impact on Telemedicine Utilization: a Retrospective Observational Study (Preprint)

BACKGROUND While telemedicine has been expanding over the past decade, the COVID-19 pandemic era restrictions regarding in-person care have led to unprecedented levels of telemedicine utilization. To the authors’ knowledge, no studies to date have quantitatively analyzed both national and regional trends in telemedicine utilization during COVID-19, both of which have key implications for informing health policy. OBJECTIVE To investigate how trends in telemedicine utilization changed across the course of the COVID-19 pandemic. METHODS Using data from doxy.me, the largest free telemedicine platform, and the NIH Clinical Center, the largest U.S. clinical research hospital, we assessed changes in total telemedicine minutes, new provider registrations, monthly sessions, and average session length from March-November 2020. We also conducted state-level analysis of how telemedicine expansion differed by region. RESULTS National telemedicine utilization peaked in April 2020 at 291 million minutes and stabilized at 200-220 million monthly minutes from May to November 2020. Surges were strongest in New England and weakest in the South and West. Greater telemedicine expansion during COVID-19 was geographically associated with lower COVID-19 cases per capita. The nature of telemedicine visits also changed, as the average monthly visits per provider doubled and average visit length decreased by 60%. CONCLUSIONS The COVID-19 pandemic led to an abrupt and subsequently sustained uptick in telemedicine utilization. Regional and institute-level differences in telemedicine utilization should be further investigated to inform policy and procedures for sustaining meaningful telemedicine use in clinical practice.
