Primary Care Appointment Completion Rates and Telemedicine Utilization Among Black and Non-Black Patients from 2019 to 2020.

To understand how differences in primary care appointment completion rates between Black and non-Black patients changed in 2020 within the context of the COVID-19 pandemic and when telemedicine utilization peaked. We conducted a retrospective cohort study using the electronic health record from January 1 to December 31, 2020, among all adults scheduled for a primary care appointment within a large academic medical center. We used mixed-effects logistic regression to estimate adjusted appointment completion rates for Black patients compared with those for non-Black patients in 2020 as compared with those in 2019 within four time periods: (1) prepandemic (January 1, 2020, to March 12, 2020), (2) shutdown (March 13, 2020, to June 3, 2020), (3) reopening (June 4, 2020, to September 30, 2020), and (4) second wave (October 1, 2020, to December 31, 2020).
