The Impact of Increased Access to Telemedicine

Abstract We estimate the impact of increased access to telemedicine following widespread adoption during the March–April 2020 COVID-19 lockdown period. We focus on the post-lockdown period, which was characterized by near-complete reopening. Using a difference-in-differences framework, we compare primary care episodes before and after the lockdown between patients with high and low access to telemedicine, as defined by their primary care physician adoption. Our results show that access to telemedicine leads to slightly more primary care visits but lower spending. Visits involve fewer prescriptions and more follow-ups, but we find no evidence of missed diagnoses or adverse outcomes. Results suggest that telemedicine does not compromise care quality or raise costs.
