The emergence of the coronavirus disease (COVID-19) pandemic in the United States in March 2020 created unprecedented challenges in the provision of scheduled health care and, in particular, ambulatory cancer care. The rapid spread of COVID-19 has renewed focus on telehealth [1], including video consultations [2], as a means of continuing ambulatory care without increasing the risk of potential exposure for patients, clinicians, and staff.

Telehealth is the provision of health care remotely by means of a variety of telecommunication platforms such as messaging, audio, and video [3]. While the use of telehealth to deliver cancer care is not new [4] and has already been well described [5], delivering it at the current scale as a result of the COVID-19 pandemic is unprecedented.

University of California, San Francisco (UCSF) Health established a telehealth program in 2015, which offers video visits in all practices. In response to the evolving pandemic, leadership challenged the organization to transition all in-person clinic visits, beginning March 15, 2020, to video visits with exceptions only for specific, urgent cases.

In this study, we analyze the change in video visit volume at the UCSF Comprehensive Cancer Center in response to COVID-19 and compare demographics and appointment data from January 1, 2020, and in the 11 weeks after the transition to video visits.

Demographics and appointment data (dates, visit types, and departments) were extracted from the electronic health record reporting database. The pre–COVID-19 period was defined as the 11 weeks from January 1 to March 13, 2020, prior to the transition, and the post–COVID-19 period as the 11 weeks following the transition to video visits on March 16, 2020, up to May 31, 2020. All video visits were performed using a HIPAA (Health Insurance Portability and Accountability Act)-compliant video conferencing platform (Zoom Video Communications Inc) with a pre-existing workflow (Figure 1). The statistical program R (version 3.5.3, R Foundation for Statistical Computing) was used for analysis [6] and a P value less than .05 was considered significant.

In the pre–COVID-19 period from January 1 to March 13, 2020, there were a total of 23,988 ambulatory care episodes, with a mean of 2181 (SD 522) episodes per week across 17 departments and divisions at the UCSF Cancer Center (Figure 2). During this period, 2284 video visits were performed, with a mean of 208 (SD 75) video visits being performed per week. The proportion of video visits ranged from 7%-18% whereas the proportion of in-person visits ranged from 76%-86% (Figure 3). In the post–COVID-19 period from March 16 to May 31, 2020, there was a total of 20,567 ambulatory care episodes (mean 1870, SD 200 per week). A total of 12,946 video visits were performed in the post–COVID-19 period (mean 1177, SD 120 per week). The proportion of video visits increased to 54%-72%. The proportion of episodes during which a procedure was performed ranged from 4%-7% in the pre–COVID-19 period and 1%-5% in the post–COVID-19 period.

Table 1 displays the demographic data of patients who had a video visit in the pre–COVID-19 period (n=2284) and patients who had a video visit in the post–COVID-19 period (n=12,946). In the post–COVID-19 period, more black/African American (531 [4.1%] vs 78 [3.4%]; P<.001), Hispanic/Latino (1450 [11.2%] vs 215 [9.4%]; P<.001), and Asian (1903 [14.7%] vs 197 [8.6%]; P<.001) patients received care via video visits compared to the pre–COVID-19 period. There was increased post–COVID-19 utilization of video visits for patients in urban areas (12,014 [92.8%] vs 2026 [88.7%]; P<.001). We did not find any difference in the insurance status of patients using video visits during either period. In the post–COVID-19 period, first clinic encounter (2822 [21.8%] vs 417 [18.3%]; P<.001) and physician-provided visits (10,590 [81.8%] vs 1538 [67.3%]; P<.001) increased.
