Intervention
Relative advantage: Participants reported a strong interest in the program and noted that nothing similar was currently available within their organizations.
Design quality: Participants were supportive of the proposed model of exercise delivery (i.e., 8-week program, offered two times per week). Specific recommendations included the target patient population and referral strategies.
Patient population.
While all participants believed in the value of the program, concerns were expressed regarding offering the program to complex patients and those on treatment. A desire to build trust among referring clinicians with an initial focus on a low-risk patient population.
Referral strategies
Participants expressed interest and confidence in facilitating referrals to the program. Several points of referral were suggested (e.g., chemotherapy education nurses prior to treatment, offboarding process with social workers, consults with oncologists); however, all participants expressed the need for a streamlined process that clearly defined eligibility criteria and program details.
Outer Setting
Patient needs and resources: barriers
Cost
While participants were excited a research grant would cover costs of the exercise program for patients, they questioned the program’s potential as a long-term solution for integration without a clear funding stream.
Transportation
Concerns were raised about patients’ ability to access the program due to transportation challenges.

And there are certain populations of patients, um, that just have so many co-morbid conditions and that are stage four, you know? And when your prognosis is limited, Those folks are probably not going to be referred to something like this.

I think we're not going to have as much success recruiting [people on treatment] just because they're just under so much, you know, time, financial, emotional, and physical stress already. It's just hard.

you're going to have referral cards…you know, the name, your fax numbers so we can get notes to you guys, and then we'll pass those out to the physicians, the mid-level providers, and then the schedulers. So when that opportunity comes up, everything can be streamlined.

A lot of these patients…don't have rides or transportation… It's just really difficult. [Many] won't make it to the treatment, but then to add in something like [exercise], I just don't see those patients using that.

We have patients that have trouble getting here…if transportation is an issue for somebody who lives close to our facility, getting them to [proposed exercise location] is obviously going to be a problem if they can barely get themselves to treatment.

Information gathered through the interviews informed the program’s referral practices and participant eligibility. Specifically, four referral sources were identified: chemotherapy education nurses, nurse practitioners and/or medical oncologists, social workers, and physical therapists. Each referral group received program flyers to post in their offices and provided contact details for the study staff to share with patients. Participant eligibility was initially limited to people who had completed primary treatment (surgery, chemotherapy and radiation) to account for concerns expressed by the clinicians in the interviews.
Phase 2: Evaluation
Reach
During the 9-month recruitment period, 1,275 people received a diagnosis at PHM. Of the 30 participants who were enrolled and completed baseline assessments, 23 completed the exercise program. This represents an overall reach of 2% and a retention rate of 70%. Reasons for withdrawal included personal reasons (3), travel time (1), and unrelated medical concerns (1). One participant withdrew due to muscle soreness following their first exercise session.
Key demographic and medical characteristics of the program participants are outlined in Table 3. The age of participants ranged from 38 to 76 years old. The majority (96%) of exercise participants were female and had a diagnosis of breast cancer (88%). Thirty-two percent (n = 8) of participants were Black and 8% (n = 2) were Asian.

Effectiveness
The small sample size and lack of control group precludes any comprehensive analysis/interpretation on changes in the BNAT and fatigue score. However, participants who completed the program experienced significant improvements in cancer-related fatigue (pre: 35.35 ± 11.56, post: 41.78 ± 9.75, p < 0.05; d = 0.60), 2-minute step test (pre: 74.54 ± 19.29, post: 92.65 ± 25.59, p < 0.05; d = 0.80), 30-second sit to stand (pre: 10.88 ± 3.88, post: 13.09 ± 5.10, p = 0.002; d = 0.49), timed arm curl (pre: 13.21 ± 3.45, post: 16.57 ± 4.37, p = 0.000; d = 0.85) and timed up and go (pre: 8.87 ± 3.49, post: 6.79 ± 22.00, p = 0.007; d = 0.74) (Table 4).

Adoption
Referral information revealed three of the four stakeholder groups initially identified adopted the program (i.e. the program received referrals from three of the four groups) (75%), with physical therapists as the most common pathway to the program, representing 60% (n = 18) of all referrals. Additional pathways included oncologists (20%; n = 6), flyers in their oncologist’s office (10%; n = 3), and “other” (10%; n = 3). Notably, the referral pathways became more diverse with each wave. Wave 1 participants (n = 9) were primarily referred by their physical therapist (n = 8; 89%), with only one participant reporting “other” (11%). Of the 11 participants enrolled and baselined during Wave 2, 73% (n = 8) were referred by their physical therapist, while the remaining 27% (n = 3) were referred directly by their oncologist. Ten participants were enrolled in Wave 3. Thirty percent (n = 3) were referred by their oncologist, 30% (n = 3) were recruited by flyers in their doctor’s office, 20% (n = 2) were referred by their physical therapist and the remaining 20% (n = 2) reported “other”.
Implementation
Program funding and delivery: The project was solely funded from a small grant funded through a partnership with the hospital and University. Program decisions were made by the SAG to ensure the program offerings were feasible within the financial constraints of the grant. Specifically, the program was offered using the existing infrastructure of the organization’s physical therapy facilities at two time points in the day: 6.30am – 7.30am and 5.30pm – 6.30pm, Monday through Thursdays. These time slots were chosen to minimize the impact of the program on current clinical operations in the physical therapy clinic.The capacity of this space allowed for four participants per hour. As mentioned above, the principal investigator of the grant (CF), designed and supervised the program. The program was delivered by undergraduate and graduate research assistants supervised by on of the PIs (CF), and who went through training in the area of exercise oncology were responsible for day-to-day program delivery with patients. The funding supported the program to be offered in 3-waves of 8-weeks across 9-months.
Program structure: The program structure (8 weeks; 2 sessions/week) remained consistent across all three waves. However, the model of delivery was changed between waves 1 and 2 in response to participant feedback. The initial program model was delivered in a 1:1 format, with each participant working through their program individually with an exercise professional. Participants expressed a desire for more interaction with other participants. As a result, SAG meeting minutes note a decision to update the delivery model to a group format. Waves 2 and 3 employed a group exercise format, whereby participants were encouraged to exercise together, alternating exercises and stations. In waves 2 and 3, exercise prescription was still individualized and monitored by on-site exercise professionals.
Participant eligibility: Initial program eligibility required that participants had completed primary treatment for their cancer based on concerns raised by clinicians during the pre-implementation phase. SAG meeting minutes clarified that study staff were integrated into the breast tumor board meetings, which took place monthly during the intervention period. Updates about the exercise program were presented to medical oncologists and nurse practitioners at each meeting. Following the second meeting (November 2021), requests were made and subsequently actioned to extend program eligibility to people on primary treatment.
Maintenance
The grant funding support for the exercise program ended in June 2022, after completion of Wave 3. The program could not continue without additional funding. Meeting minutes from the SAG noted the results of a presentation by the study PI (CF) of the program’s preliminary findings to the breast tumor board on January 25th, 2022. The presentation resulted in a decision by the breast tumor board to fund a PhD student to ensure the program could continue. This funding is provided on an annual basis, pending progress reports to the tumor boards, and shifts in funding budget/priorities. Under the supervision of the study PI (CF), this funded PhD student would oversee a team of graduate and undergraduate students responsible for program delivery.
