Introduction: With recent advances in digital communications technology and the backlog of cancer care resulting from the COVID-19 pandemic, the demand for telemedicine has skyrocketed. The latest evidence suggests that high-quality oncological care can be delivered by means of telemedicine, with some caveats. Against this backdrop, we sought to analyze the use of telemedicine among cancer survivors, hypothesizing that its use may be higher for certain oncological conditions relative to others.Materials & Methods: We conducted a cross-sectional study on cancer patients using data between July and December 2020 in the National Health Interview Survey (NHIS). We utilized an affirmative answer to “Have you EVER been told by a doctor or other health professional that you had Cancer or a malignancy of any kind?” to identify patients with cancer history. We used the question “In the past 12 months, have you had an appointment with a doctor, nurse, or other health professional by video or by phone?” to identify telemedicine recipients. Survey-weighted multivariable Poisson regression analysis adjusted for potential confounders was conducted to estimate risk ratios (RR) for receipt of telemedicine, and a two-way interaction between currently receiving treatment and cancer type was assessed for any effect modification. Results: We Identified 2,389 individuals with a cancer history, representing a weighted population of 12.312 million. The prevalence of telemedicine utilization was 44% (see Table1). Relative to breast cancer survivors, we found that PCa was a significant predictor of receipt of telemedicine (RR: 1.39, 95% CI: [1.06-1.81], P= 0.02), (see Table2). A significant interaction was found between those currently receiving treatment for cancer and cancer type Pint<0.01; marginal probability analysis showed that patients currently receiving PCa treatment were more likely to receive telemedicine in comparison to those not on treatment, with an adjusted risk difference of 0.18, (95% CI[0.01-0.35], P=0.04) (see Table3). Conclusions: Our study suggests that telemedicine appointments were widely used among cancer survivors in 2020, with PCa survivors more likely to use telemedicine compared to other malignancies. Such findings may point to wider adoption of telemedicine among urologists, as suggested by other studies, or that PCa care lends itself better to telemedicine, compared to other malignancies. Future studies should focus on understanding the dynamics of such patient- and provider-level factors.

CI; confidence interval. The survey's response rate was 48.9%. Respondents who reported ever being diagnosed with cancer were included in the analysis, respondents who answered no, refused to answer, were not certain, or did not know were excluded from the analysis. Respondents who reported multiple cancers were grouped with other cancers, and all other cancer types were from participants reporting one cancer |
