These data are the foundation for our manuscript, Impact of COVID-19 on gynecologic and obstetrical services at two large health systems. Comparing 2020 to 2019, we quantified changes to obstetrics and gynecology care at two large health care organizations in the United States. The analysis considered the 2020:2019 ratios, by time period, for the number of gynecologic surgical encounters, in-person visits, and telemedicine visits. For each system, we quantified temporal changes in surgical volume, in-person and telemedicine visits, and financial impact related to professional fee revenues.
