On the demand for telemedicine: Evidence from the COVID-19 pandemic.

Telemedicine can expand access to health care at relatively low cost. Historically, however, demand for telemedicine has remained low. Using administrative records and a difference-in-differences methodology, we estimate the change in demand for telemedicine experienced after the onset of the COVID-19 epidemic and the imposition of mobility restrictions. We find that the number of telemedicine calls made during the pandemic increased by 230 percent compared to the pre-pandemic period. The effects were mostly driven by older individuals with preexisting conditions who used the service for internal medicine consultations. The demand for telemedicine remained relatively high even after mobility restrictions were relaxed, which is consistent with telemedicine being an "experience good." These results are a proof of concept for policy makers to use such relatively low-cost medical consultations, made possible by new technologies, to provide needed expansion of access to health care.
