Patient Provider Communication Larch Supplement

PROJECT SUMMARY This application is being submitted in response to the Notice of Special Interest (NOSI) identified as NOT-CA- 23-041. Screening for lung cancer has the potential for a profound public health benefit; however, adherence to lung cancer screening remains low in the United States. Multilevel digital health interventions, which target

patients, clinicians, and healthcare systems, offer a promising solution to address the gaps in lung cancer screening. Digital health can improve patient-centeredness in interventions by increasing patient reach, accessibility, and understanding through education. We propose to leverage the unique infrastructure of the

Larch trial (R01CA262015) via the proposed supplemental study in response to NOT-CA-23-041. The proposed supplemental study is within the scope of parent grant, a pragmatic randomized trial testing patient- centered interventions to promote adherence to repeat lung cancer screening. One intervention being tested is

the Patient Voices Video, an educational video for patients, which is delivered via Kaiser Permanente Washington patient portal after a negative lung cancer screening scan. The supplemental study goal is to define and understand which populations would be responsive to digital health communication for lung cancer

screening using the Patient Voice Video as a ‘use case’. More importantly, our findings will also identify which patient populations are not reached via digital health messaging, which can influence future focal areas to increase equity in digital health messaging for cancer screening. For this supplemental study, our aims are: 1)

Evaluate patient-, provider- and system-factors associated with Kaiser Permanente Washington patient portal access and engagement with video messaging in the portal; and 2) Understand patient engagement with Patient Voices Video and attitudes toward multimedia screening interventions with key informant interviews.

The proposed mixed-methods supplement study will improve our understanding of patient engagement with digital health interventions, with high potential to inform future research to improve lung cancer screening and increase equity in cancer care delivery.
