Abstract

Abstract: Background: Mobile health apps are increasingly gaining attention as opportunities to obtain patient-generated health data without asking for self-report or visiting hospital. Since there are few studies regarding the mobile-based activity trackers in breast cancer patients, we decided to evaluate the feasibility of a mobile walking app and a smart band as a tool for collecting physical activity of breast cancer patients. Methods: Between June 2017 and March 2018, patients who received surgery for breast cancer at Asan Medical Center were enrolled and asked to access two mobile apps on a weekly basis during a six-month period to automatically record their daily physical activity. Compliance rates of the daily collection via a smartphone walking app and a wearable smart band were compared in a within-subject manner. Longitudinal daily collection rates were calculated to examine a drop-out pattern. Finally, we examined factors associated with the compliance of daily collections using multivariate linear regression analysis. Results: A total of 160 participants were analyzed, and they are asked to follow an instruction to access the apps at least once a week via their smartphones. Despite the fact that both smartphone app and the smart band showed more than 50% of compliance rate during the six-month follow-up period, smartphone walking app demonstrated higher overall compliance rate (88%) than a smart band (52%). The median value of individual compliance rate is 91% for the walking app and 55% for a smart band. Women having other diseases, an anti-hormonal therapy or a targeted therapy show a higher compliance rate to smartphone walking app, and young women show a higher rate to the app than older women. However, there was no association between any of the patient characteristics and a compliance rate to the smart band. Conclusions: Smartphone apps or smart bands are feasible tools to collect daily physical activity data for in breast cancer survivors. Legal entity responsible for the study: Yungil Shin.
