Compiled by the New York-based telehealth scheduling company Zocdoc, the survey, taken separately of patients and care providers between May 2020 and May 2022 and combined with an analysis of appointment bookings, charts the increase in telehealth visits during the pandemic and a decrease in recent months as the COVID-19 crisis has waned. It found that roughly one-third of all visits were virtual in 2020, as the pandemic peaked, and that number dropped to 17% as of May 2022.

Unlike synchronous telehealth, which basically consists of a two-way, real-time audio-video feed between patient and care provider, asynchronous telehealth doesn’t involve real-time communication, and most often doesn’t include video. Consumers enter information into an online platform at their own time and convenience, usually through a questionnaire, and a care provider accesses that data on the other end then responds with a diagnosis and treatment plan. It can be done by phone or computer and include images and even video, but the key factor is that both patient and provider can access the platform at the time and place of their choosing.
