building a physical activity intervention into clinical care for breast and colorectal cancer survivors in wisconsin: a randomized controlled pilot trial

Cancer survivorship care plans (“care plans”) often recommend an active lifestyle yet are rarely accompanied by programs to help patients enact the prescribed behavior change. as a step towards bridging this gap, this trial tested the feasibility of augmenting care planning with a multi-level physical activity intervention. breast and colorectal cancer survivors were enrolled alongside a self-selected support partner (e.g., spouse, friend). survivors received a care plan alone (comparison group) versus one augmented with a 12-week physical activity module (intervention group). for the intervention group dyads, both members received a multi-component program including fitbit trackers, with the survivor’s fitbit linked to his/her electronic health record (ehr). treating clinicians received periodic updates regarding the survivors’ physical activity. the primary outcome was actigraph-measured physical activity, analyzed using mixed models. feedback questionnaires were administered to participants and clinicians at 12 weeks. survivors (n = 50) were 54.4 ± 11.2 years of age and 2.0 ± 1.5 years post-diagnosis. survivors in the intervention group increased moderate-to-vigorous-intensity physical activity (mvpa) by 69 ± 84 min/week vs. a 20 ± 71 min/week decrease in the comparison group (p = .001). likewise, daily steps increased by 1470 ± 1881 vs. a 398 ± 1751 decrease (p = .002). among responding clinicians, 100% looked at survivors’ activity data within the ehr at least once and 80% said it provided insight into their patients’ lifestyles. augmenting a standard care plan with a multi-level, technology-based intervention increased physical activity among cancer survivors. technology-based approaches, including activity trackers, can be used by individuals to work towards an active lifestyle after cancer.
