Relative change in the average weekly visit volume comparing the pandemic period to the prepandemic period

Country	Total visit volume		Virtual visit volume

USA	0.89 (0.82 to 0.96)	0.005	–	–

For countries with virtual care before and after the pandemic onset (Norway, Sweden and the UK), relative change in the weekly virtual visit volume is presented.

Prepandemic period=weeks 12–52 in 2019, except in China where it was weeks 5–52 in 2019.

Pandemic period=weeks 12–52 in 2020, except in China where it was weeks 5–52 in 2020.

*Unlike the other INTRePID countries, the number of clinics that contributed data for UK varied over time. An offset for the total number of patients covered for each week was added to the Poisson regression to account for this. For this reason, the RR is not directly comparable with the other countries.
