Navigating the cyber shift: The trends of electronic health record (EHR) engagement in oncology.

e13718 Background: Oncology has evolved in the cyber era of medicine. The 21 st Century Cures Act mandated patient access to medical data (tests, provider notes) via patient portals connected to EHRs in order to facilitate patient engagement. Furthermore, the COVID-19 pandemic rapidly transformed patients’ interactions with portals by increasing reliance on telehealth and portal messaging. This shift has been well-documented in primary care, and emerging research suggests similar trends in oncology. More information is needed regarding how this has evolved post-pandemic. We present single academic institution real-world data (RWD) describing ongoing changes in patient messages and telephone calls in oncology. Methods: We quantified the changes (2019-2024) within oncology at Mayo Clinic Rochester campus including all care team, provider, nursing, and pharmacist visits, patient portal medical advice requests, patient calls, and messages sent to patients per year using Epic's SlicerDicer™ tool. Results: Patient visits/year dipped (-0.2%) from 2019 to 2020, but increased steadily from 2021 forward (Table 1). Patient portal advice requests increased significantly faster (Table 1); from 2019 to 2024, visits /year increased by 40%, while the number of advice requests increased by 131%. Patient calls/year increased more modestly (64%), while the number of messages sent to patients increased by 163% over this time. Conclusions: The transparency allowed by the Cures Act coupled with the impact of the pandemic has empowered patients to engage in their oncology care more proactively through the EHR. Patient-initiated portal messaging is increasing, with messages sent to patients from the oncology department similarly rising. Patient call volumes are also growing despite EHR messaging. Further research is necessary to better understand patterns of EHR use in oncology and explore ways to reduce clinician burnout that may arise from responding to this increased communication volume, as well as to understand the impact on patient satisfaction and outcomes. Changes in patient volume compared to patient calls and EHR messaging over time.
