A Mobile App to Stabilize Daily Functional Activity of Breast Cancer Patients in Collaboration With the Physician: A Randomized Controlled Clinical Trial

Abstract

BackgroundThe well-being of breast cancer patients and reporting of adverse events require close monitoring. Mobile apps allow continuous recording of disease- and medication-related symptoms in patients undergoing chemotherapy.ObjectiveThe aim of the study was to evaluate the effects of a mobile app on patient-reported daily functional activity in a supervised and unsupervised setting.MethodsWe conducted a randomized controlled study of 139 breast cancer patients undergoing chemotherapy. Patient status was self-measured using Eastern Cooperative Oncology Group scoring and Common Terminology Criteria for Adverse Events. Participants were randomly assigned to a control group, an unsupervised group that used a mobile app to record data, or a supervised group that used the app and reviewed data with a physician. Primary outcome variables were change in daily functional activity and symptoms over three outpatient visits.ResultsFunctional activity scores declined in all groups from the first to second visit. However, from the second to third visit, only the supervised group improved, whereas the others continued to decline. Overall, the supervised group showed no significant difference from the first (median 90.85, IQR 30.67) to third visit (median 84.76, IQR 18.29, P=.72). Both app-using groups reported more distinct adverse events in the app than in the questionnaire (supervised: n=1033 vs n=656; unsupervised: n=852 vs n=823), although the unsupervised group reported more symptoms overall (n=4808) in the app than the supervised group (n=4463).ConclusionsThe mobile app was associated with stabilized daily functional activity when used under collaborative review. App-using participants could more frequently report adverse events, and those under supervision made fewer and more precise entries than unsupervised participants. Our findings suggest that patient well-being and awareness of chemotherapy adverse effects can be improved by using a mobile app in collaboration with the treating physician.ClinicalTrialClinicalTrials.gov NCT02004496; https://clinicaltrials.gov/ct2/show/NCT02004496 (Archived by WebCite at http://www.webcitation.org/6k68FZHo2)

eHealth and mHealth interventions in the treatment of fatigued cancer survivors: A systematic review and meta-analysis

“…There are few published studies that have utilized smartphone applications as part of interventions aimed at altering health behaviors in a population of cancer patients or survivors. Most of this published literature has focused on interventions designed to enhance disease management—ranging from appointment reminders, to applications to aid in symptom recording to enhance subsequent patient‐doctor discourse, to education regarding the patient's diagnosis and treatment—or to promote adherence to dietary and physical activity guidelines . Although these studies were limited by small sample sizes and short follow‐up periods, the efficacy of mHealth interventions was consistently reported in terms of better management and delivery of cancer care, improved physical activity, and more healthy living.…”

Mobile Breast Cancer e-Support Program for Chinese Women With Breast Cancer Undergoing Chemotherapy (Part 2): Multicenter Randomized Controlled Trial (Preprint)

“…A sample of 108 participants (54 participants per group) was needed to detect an effect size of at least 0.60, with 80% power, two-sided P<.05, and 20% attrition. A dropout rate of 10-20% were reported in previous studies involving an app-based study [9,24]. Finally, the recruitment numbered 114 participants in total (57 participants per group).…”

Healthcare professionals knowledge on cancer‐related fatigue: A cross‐sectional survey in Oman

“…This would permit remote monitoring of patients with fatigue through an online system, which could incorporate evidence‐based practice and guidelines to monitor and improve fatigue throughout the treatment of cancer. Related research using mobile apps has found positive experiences for patients with cancer and HCPs (Egbring et al, 2016; Rincon et al, 2017; Young‐Afat et al, 2016). In Oman, smartphone use has increased by 154% over the last 3 years (Ministry of Transport and Communications, 2017), with most of the population having a smartphone.…”
