a For any virtual/telehealth (TH) use, in the pre-COVID segment, there was evidence of a slight increasing monthly trend in telehealth use. At the onset of COVID-19 (month 13, March 2020), rate of any telehealth use showed a highly significant, near-threefold increase of 28 percentage points (p < .001), and use showed significant monthly increases until the reauthorization of in-person services (month 16, June 2020). Rate of telehealth use then showed an immediate and significant dramatic reduction of 25 percentage points (p < .001) followed by a continued significant monthly reduction (p < .001). At the start of the 2020 flu season (month 20, November 2020), however, telehealth use showed a modest but significant increase followed by a significant monthly increase through the end of the time series. b For video-based care, however, different patterns of use emerged after the onset of COVID-19. Like telehealth use, before onset of COVID-19, there was evidence of an increasing monthly trend in video use (VVC). At the onset of COVID-19, however, there was a slight but significant decrease in video use, but this immediate reduction was followed by a sharp and highly significant increase until re-expansion of in-person services (month 16, June 2020), at which point video use had increased nearly eightfold. Video use then showed a slight immediate decrease, followed by a significant monthly increase until the start of the 2020 flu season (month 20, November 2020). Video use then showed a sharp and significant 20% decrease followed by a small but significant monthly decrease in video use until the end of the time series
