Mobile app care utility: Patients and caregivers perception.
157 Background: There is increasing appreciation for the insight provided by combining low-burden home-based remote digital measurements with patient and observer reported outcomes. In this study, we assessed perspectives of cancer patients and their caregivers on the utility of a mobile app combined with a smartwatch for collection of specific outcomes and to provide clinically actionable data. Methods: In a decentralized clinical trial we consented and enrolled (10/12/2020-4/30/2021) dyads that consisted of a cancer patient and their informal caregiver. All participants had to own an Apple iPhone 6 or higher. Patients were provided with an Apple watch 3 or 4 and downloaded a patient informed mobile app (DigiBioMarC). Caregivers only download a caregiver informed mobile app (TOGETHERCare). Participants were asked to use their respective app for 28 days during which time specific surveys and activity requests were delivered through the mobile app; digital measures of physical activity were collected via the smartwatch. At the end of the app usage period, questions were asked in a video interview about the patient and caregiver perspectives on use of their respective apps and what they believed could be impacted if their doctor were to receive the app information. Respondents could select Strongly Agree, Agree, Neutral, Disagree, or Strongly Disagree. Results: Fifty-four dyads were enrolled; four were unable to continue due to a decline in health. Questions were drafted and IRB approved in time to be asked of 45 dyads. The Table lists some results and the percent of respondents that selected Strongly Agree or Agree. Conclusions: Patients and caregivers reported that both apps would encourage them to take better care of themselves/be more physically active and would improve emotional wellbeing. A high proportion of respondents also felt the apps would improve communication with their doctor and provide early important information for the doctor to act upon compared to usual care. Additional work in a large randomized trial is planned to evaluate specific care outcomes. [Table: see text]
