Abstract LBA74


The COVID-19 pandemic has rapidly altered cancer care. However, the ways in which it has done so and the associated impact at the individual and societal levels remains poorly defined.


CCOS is a multicenter prospective cohort study designed to define the impact of the pandemic on cancer care delivery and outcomes. The CCOS cohort comprised consecutive outpatients with cancer seen at two US cancer centers from March 2 to March 6, 2020 (index visit). Data was collected at baseline, retrospectively from the preceding 3 months, and prospectively at 3-month follow up. Per patient changes in numbers of visits were compared using Wilcoxon signed rank tests. Correlates of increases in telehealth visits and decreases in in-person visits were evaluated using multivariable logistic regression models. Adjusted Odds ratios [aOR] and 95% confidence intervals (CI) were reported.


Of 2365 included patients, 1219 (51.6%) had a decrease in in-person visit frequency during the pandemic period relative to the preceding 3 months. Conversely, 760 (32.2%) had an increased frequency of telehealth visits (decrease in in-person and increase in telehealth visits; both p<0.01). 128 (5.4%) patients developed COVID-19. Compared to White patients, Black and Hispanic patients were less likely to have telehealth visits, had no significant change in frequency of in-person visits, and were more likely to develop COVID-19 (Table).

N (%); aOR (95% CI)*
Increase in telehealth visits Decrease in in-person visits COVID-19 diagnosis
Non-Hispanic White 508 (37.8%) 1.00 (control) 716 (53.3%) 1.00 (control) 47 (3.5%) 1.00 (control)
Non-Hispanic Black 69 (23.8%) 0.69 (0.50 – 0.94) 151 (50.5%) 0.93 (0.70 – 1.23) 27 (9.0%) 1.86 (1.10 – 3.11)
Hispanic 65 (21.9%) 0.71 (0.51 – 0.98) 154 (51.9%) 1.10 (0.83 – 1.46) 41 (13.8%) 3.19 (2.00 – 5.10)
Other 43 (25.9%) 0.90 (0.60 – 1.32) 82 (49.4%) 0.93 (0.65 – 1.32) 2 (1.2%) 0.25 (0.04 – 0.84)

* Adjusted for cancer disease group, cancer center, cancer status, and receipt of systemic therapy (during index week).


Significant disruptions to routine cancer care were observed during the pandemic period relative to the prior 3 months. Racial and ethnic barriers to the adoption of telehealth, and related socioeconomic factors, place these vulnerable populations simultaneously at disproportionate risk for decreased cancer-related visits and COVID infection, thereby exacerbating existing racial and ethnic health disparities.
