The necessity of OPPC increased during SARS-CoV-2/COVID-19, yet investigations in vulnerable subgroups have been limited. Objective: This study aims to assess the prevalence of OPPC and sociodemographic and clinical characteristics associated with OPPC among cancer survivors and adults without a history of cancer during COVID-19 versus pre--COVID-19. Methods: Nationally representative cross-sectional survey data (Health Information National Trends Survey 5, 2017-2020) were used among cancer survivors (N=1900) and adults without a history of cancer (N=13,292). COVID-19 data included data from February to June 2020. We calculated the prevalence of 3 types of OPPC, defined as using the email/internet, tablet/smartphone, or electronic health record (EHR) for patient-provider communication, in the past 12 months. To investigate the associations of sociodemographic and clinical factors with OPPC, multivariable-adjusted weighted logistic regression was performed to obtain odds ratios (ORs) and 95{\%} CIs. Results: The average prevalence of OPPC increased from pre-COVID to COVID among cancer survivors (39.7{\%} vs 49.7{\%}, email/internet; 32.2{\%} vs 37.9{\%}, tablet/smartphone; 19.0{\%} vs 30.0{\%}, EHR). Cancer survivors (OR 1.32, 95{\%} CI 1.06-1.63) were slightly more likely to use email/internet communications than adults without a history of cancer prior to COVID-19. Among cancer survivors, the email/internet (OR 1.61, 95{\%} CI 1.08-2.40) and EHRs (OR 1.92, 95{\%} CI 1.22-3.02) were more likely to be used during COVID-19 than pre--COVID-19. During COVID-19, subgroups of cancer survivors, including Hispanics (OR 0.26, 95{\%} CI 0.09-0.71 vs non-Hispanic Whites) or those with the lowest income (US {\$}50,000-
