Brief summary

This clinical trial compares how well a home-based personalized physical activity program (PAP) that is delivered by a digital application (app) (the ExerciseRx app) works compared to health education in improving physical activity for patients with bladder cancer that has not reached the muscle wall of the bladder (non-muscle invasive). For people who are not physically active, previous studies have shown that increasing step counts can reduce incidence of death, reduce frailty, and reduce healthcare costs. The ExerciseRx app tracks adherence to home exercise, adapts step count goals based on the patient's progress, and provides encouraging feedback and motivation from the healthcare team. Additional features include activity summaries, progress towards current goal, nudges, helpful facts about the benefits of activity, and ideas for how to incorporate daily movement. A home-based PAP using the ExerciseRx app may work better in increasing physical activity among patients with non-muscle invasive bladder cancer compared to a health education only group.

Detailed description

OUTLINE: Patients are randomized to 1 of 2 groups. GROUP I (Health Education Group, HEG): Patients receive recommendations from their physicians and an educational pamphlet describing physical activity goals in line with National Comprehensive Cancer Network (NCCN) Survivorship for Healthy Living Guidelines. They receive a FitBit® to wear continuously throughout the study, with the ExerciseRx app locked to the baseline home screen. GROUP II (PAP INTERVENTION): Patients complete home exercise sessions given via the ExerciseRx app over 20-30 minutes 4 times per week for 12 weeks and receive personalized daily step count goals that gradually increase over the study period. Patients also receive a FitBit® to wear continuously throughout the study, are given access to features of the ExerciseRx app (step count goals, home exercise videos), and receive an educational pamphlet as in Group I. After completion of the study intervention, patients are followed up at 4 weeks.

Design outcomes

Primary

MeasureTime frameDescription
Change in mean daily step countBaseline (1 week prior to trial initiation) and timepoint 2 (12 weeks)Average daily step count (per 24-hour day) will be assessed by the Fitbit tracker. Summary statistics (mean and standard deviations; counts and percentages) will be used to describe and compare baseline characteristics between the two treatment arms. Will use a linear mixed effects model with average daily step count as the outcome, with fixed effects for time (T1, T2, and T3), treatment assignment, and the week-treatment interaction, and a random intercept for each participant. A significant interaction between T2 and treatment assignment will indicate the change in step count from baseline to T2 differs between the two treatment arms and will be used to evaluate the co-primary outcomes of step-count improvement at the end of treatment using a two-sided significance level of 0.05. The minimum amount of time that participants need to have worn the Fitbit for their step data to be valid for use in analysis is one week (7 days) post baseline period.
Qualitative experienceWeek 16Will be assessed by Zoom interviews (usability interview) with a subset of volunteer participants from the physical activity program (PAP) arm. Will analyze the semi-structured interview data using a process of reflexive thematic analysis, drawing on our reflexivity as designers, health informatics researchers, and clinical researchers to interpret data and construct themes using affinity analysis to identify ways in which ExerciseRx can be improved to meet the needs of patients with bladder cancer. Similarly, will apply the Discover Design Built Test framework from the University of Washington ALACRITY Center to adapt the ExerciseRx provider dashboard for healthcare providers caring for patients with bladder cancer.
