e13890 Background: Many oncology practices have reported continued use of telemedicine since onset of the COVID-19 pandemic. However, the future sustainability of telemedicine within oncology practices remains unclear, particularly because federal policies that enabled adoption in response to the public health emergency (PHE) have not been made permanent. Understanding similarities and differences in telemedicine utilization at high-volume oncology centers is crucial for shaping evidence-based policy that enables equitable access to oncology care across varying geographies. Methods: This is a cross-sectional, year-over-year, retrospective cohort analysis of trends in telemedicine utilization across all medical oncology clinical appointments conducted among adult patients (age >18) from January 2019 to December 2023 at Stanford Medicine Cancer Center (SM) – comprising multiple campuses in the California Bay Area – and the Mayo Clinic Comprehensive Cancer Center (MC) – a multiregional cancer practice with tertiary referral campuses in Minnesota, Florida, and Arizona, as well as community-based clinics throughout the Upper Midwest. Results: Both institutions exhibited a similar trend in telemedicine adoption over time. This was characterized by an initial surge in utilization following the PHE declaration in March 2020, followed by sustained utilization rates from 2021 to 2023. However, telemedicine use as a proportion of the overall practice differed significantly between institutions. At SM, the rate of telemedicine visits as a proportion of overall clinical practice was 60.3% (49,136/ 81,502) in 2021, 59.9% (52,247/ 87,215) in 2022, and 57.2% (55,007/ 96,163) in 2023. At MC, the proportion of telemedicine utilization was 12.8% in 2021 (23,873/186,086), 14.7% in 2022 (28,985/196,777), and 14.0% in 2023 (30,208/215,941). Deployment in the setting of new versus return visits also differed between institutions. In 2023, telemedicine accounted for 53.7% (6,440/11,998) of new and 57.7% (48,567/84,165) of return visits at SM, compared to 15.5% (3,359/21,728) and 13.8% (26,849/194,213) at MC. Additionally, while video visits were the predominant modality used to conduct telemedicine visits at both institutions from 2021 onward, in 2023 phone visits still made up 17.9% (5,394/30,208) of all telemedicine visits at MC, compared to just 5.4% (2,990/55,007) at SM. Conclusions: Stanford Medicine and Mayo Clinic exhibited a pattern of initial growth of telemedicine adoption in 2020, followed by sustained utilization from 2021-2023. We observed unique differences in the overall proportion, visit type deployment, and modality of telemedicine utilization between institutions. However, this study confirms telemedicine visits have remained a fixture of medical oncology care for many patients at these institutions since the COVID-19 pandemic.

17 Background: Age-appropriate colon cancer screening has long demonstrated effectiveness in reducing colon cancer incidence and mortality. However, despite a gradual rise in compliance with colon cancer screening, significant disparities remain, particularly among patients with limited English proficiency (LEP). Multitarget stool DNA (MT-sDNA) testing (Exact Sciences, Madison, WI) has been available over the past decade in the United States as a lower-cost and non-invasive option for screening. In 2019, Exact Sciences began to offer patient navigation services comprising outbound phone, text, and e-mail reminders, and inbound phone support (>200 languages) with all MT-sDNA orders. In this study, we aimed to evaluate the disparity in successful MT-sDNA testing between LEP and EP patients in a time frame when patient navigation services were active. Methods: We performed a retrospective cohort study of patients 45-75 years old enrolled in the primary care setting of our institution who received an order for MT-sDNA screening during a period in which patient navigation services began to be offered. A multi-state Cox model was constructed with time to MT-sDNA or other CRC screening predicted by English proficiency accounting for age and gender. Wald tests were used to test the association of CRC screening completion and English proficiency. Rates of completion of MT-sDNA screening and other CRC screening following MT-sDNA test ordering were calculated using the Kaplan-Meier method. Results: Of the 5016 patients evaluated and referred for multitarget stool DNA testing from May 1st, 2021, and May 1st, 2022, 154 patients were of LEP, and 4862 were English proficient (EP). At 180 days following a MT-sDNA test order the rate of completion for the LEP patients was 50.2% (95% CI: 42.8-58.7%) versus 70.3% (95% 69.1-71.6%) for EP individuals (p=0.001). A small portion of individuals also completed another type of CRC screen, 3.3% for LEP and 2.5% for EP (p=0.99). Conclusions: This study is consistent with the existing research demonstrating LEP as a significant demographic group linked with decreased participation in cancer screening. Our findings indicated that despite the availability of patient navigation services, individuals with LEP were still less likely to complete an MT-sDNA test successfully when compared to those with EP.
