Daily Collection of Physical Activity Data via Smartphone Application and Smart Band for the Development of Distress Screening Tools in Breast Cancer Survivors: A Feasibility Study
ABSTRACT
Background:
Mobile health applications (‘apps’) are increasingly gaining attention as opportunities to more easily obtain patient-generated health data without asking to self-report or visit a hospital. Data ubiquitously collected by mobile devices may be integrated into clinical practices to improve the quality of life of cancer survivors. Although a number of studies have focused on the feasibility of mobile-based self-reporting systems as potential tools to collect daily physical activity (PA) data among cancer patients, few studies have examined the feasibility of mobile-based activity trackers in these patients.
Objective:
This prospective observational study evaluated the feasibility of a mobile walking app and a smart band as a tool to collect PA data from breast cancer patients and analyzed the characteristics affecting compliance with those mobile technologies.
Methods:
Patients who received surgery for breast cancer at Asan Medical Center between June 2017 and March 2018 were enrolled and asked to use both a smartphone app and smart band for 6 months. The overall compliance rates of the daily PA data collection via the smartphone walking apps and wearable smart bands were analyzed in a within-subject manner. The longitudinal daily collection rates were calculated to examine the drop-out pattern. Finally, we performed multivariate linear regression analysis to examine factors associated with compliance with daily collection.
Results:
A total of 160 female patients who underwent breast cancer surgeries were enrolled. The overall compliance rates for using a smartphone app and smart bands were 88.0% (24,224/27,513) and 52.5% (14,431/27,513), respectively. The longitudinal compliance rate for smartphone apps was 77.8% at day 180, while the longitudinal compliance rate for smart bands rapidly decreased over time, reaching 17.5% at day 180. Subjects who were young, with other comorbidities, or receiving anti-hormonal therapy or targeted therapy showed significantly higher compliance rates to the smartphone app. However, no factor was associated with the compliance rate to the smart band.
Conclusions:
Smartphone apps or smart bands are feasible tools to collect data on daily PA in breast cancer patients. Further research should focus on how to interpret and integrate these data into clinical practices for cancer survivorship care. Clinical Trial: NCT03072966
