Choose to Move (CTM) is a 3-month, choice-based health-promoting program for low active older adults being scaled-up across British Columbia (BC), Canada. Recently, the investigators adapted CTM for the \>14000 people in BC who are on surgical waitlists for total knee replacement or total hip replacement (TKR/THR) for osteoarthritis (OA). The primary goals of this observational study are to describe how the adapted program, Choose to Move Replacement Ready (CTM-RR), is implemented in BC and determine if the adapted program improves health outcomes in people with hip and/or knee osteoarthritis who are on surgical waitlists for TKR/THR. The investigators will also evaluate whether any health benefits achieved by CTM-RR participants are maintained three months after they finish the program and also during the remaining time that they wait for their TKR/THR surgery.
The investigators will work with referral partners from hospitals and orthopaedic clinics in BC to recruit participants into CTM-RR. Participants who enrol in CTM-RR will answer online survey questions about the program and about their physical activity, mobility, pain, function, quality of life, willingness to undergo surgery, overall perception of their joint condition, psychosocial health, self-efficacy, social isolation, loneliness, and sedentary time. CTM-RR activity coaches will also answer online survey questions about the program. CTM-RR participants, activity coaches, and referral partners will also participate in interviews about the program.
Activity coach hired by the Active Aging Society (activity coaches must speak English to participate in the evaluation);
English-speaking older adults (aged >=50 years) who participate in CTM-RR will be invited to participate in the evaluation;
Referral partner (People who work in a healthcare setting who refer patients into the program)
non-English speaking activity coach
non-English speaking referral partner
Single group
Choose to Move Replacement Ready
BehavioralAs described under study arm description.
Implementation outcome: Fidelity (Proportion of participants who adhered to CTM-RR program components)
Obtained from post-program survey. Measures adherence to prescribed frequency, intensity, duration, and type of exercises performed, and attendance at CTM-RR group meetings.
Effectiveness outcome: Change in physical activity
Single-item physical activity questionnaire. Output measure is self-reported number of days engaging in ≥30 minutes of moderate-to-vigorous physical activity in the past week (range 0-7). Higher scores reflect a better outcome (i.e. increased physical activity)
Reach
Number of individuals participating in CTM-RR programs will be obtained from program records
Retention
Obtained from evaluation records. Proportion of participants who consent to the evaluation who complete each assessment.
Dose delivered
Obtained from post-program survey. Proportion of required intervention components (group meetings and one-on-one consultations) delivered by activity coaches.
Adoption
Obtained from program records. Number of referral partners who refer participants to the program.
Perceived participant responsiveness (survey)
Perceived participant responsiveness will be assessed via participant (older adults) survey ( short answer responses; developed in house). Older adults will indicate which optional intervention components they engaged in (peer check-in, e-mail newsletter, hip and knee exercises; yes/no response options)
Acceptability - CTM-RR program
Acceptability of Intervention Measure (AIM). Activity coaches' perception that CTM-RR is agreeable or satisfactory will be assessed by survey (4 items each on a 1-5 Likert scale with 1 being completely disagree and 5 being completely agree).
Appropriateness - CTM-RR program
Intervention Appropriateness Measure (IAM). Extent to which CTM-RR fits the needs of the target population will be assessed by survey (4 items each on a 1-5 Likert scale with 1 being completely disagree and 5 being completely agree)
Feasibility - CTM-RR program
Feasibility of Intervention Measure (FIM). Activity coaches' perception that CTM-RR is feasible to deliver will be assessed by survey (4 items each on a 1-5 Likert scale with 1 being completely disagree and 5 being completely agree).
