Supporting Uptake of Evidence for Physical Activity in Older Adults With Complex Health Care Needs

Rationale:

Physical activity is effective in preventing the progression of frailty and further disability in community-dwelling frail older adults. It is also effective in mitigating the progression of chronic conditions associated with physical frailty. Despite the benefits, many older adults in the early state of frailty and with chronic conditions are not sufficiently active. Current delivery of physical activity recommendations can be improved by applying the new Canadian 24-hour Movement Guidelines. These guidelines promote a balance of activity, rest and sleep as they play an important role for better overall health and quality of life regardless of health conditions. With advanced training in complex chronic conditions and physical activity promotion, physiotherapists (PTs) are well-suited to adapt and integrate activity counselling, based on the 24-hour Movement Guidelines, in their clinical practice.

Aim:

to assess implementation context, feasibility, and preliminary effect of the 24-hour Approach against a current goal-oriented counselling approach (i.e., focus on achieving 150 minutes/week of MVPA).

Previous Work:

A PT-led goal-oriented counselling program was previously evaluated for older adults with osteoarthritis. In 2 randomized controlled trials (RCTs), compared to controls, this program was shown to improve time spent in Moderate/Vigorous Physical Activity (MVPA) in participants after 8 weeks (n=61; 25.6 mins/day; 95% CI. 9) and 13 weeks (n=51; 13.1 mins/day; 95% CI. 5). This current approach has been modified for remote delivery during the COVID-19 pandemic.

Research Design & Data Analysis:

This is a multi-method study. PTs and their patients across Canada who have participated in the co-development of the 24-hour Approach will be invited to participate. The 24-hour Approach will be assessed in a randomized pilot study with 20 PTs and their patients (each PT will treat 4 older adult patients) who will be assigned to one of the groups:

• Current Approach (focus on achieving 150 min/week of MVPA).
• 24-hour Approach (focus on increasing MVPA with a balance of activity, rest and sleep in a day).

Guided by the RE-AIM framework, Reach will be assessed by comparing characteristics of older adult participants with those who are eligible yet decline to participate. Effect (Preliminary) will be evaluated at the older adult level. Adoption will be assessed by comparing the demographic and practice characteristics between the participating PTs and those who are eligible but have not enrolled. Implementation will be assessed by PT interviews when they complete their sessions with all 4 older adult patients. To assess Maintenance, PTs will be interviewed at 12 months about if/how they continue using their assigned counselling strategy after the study. Results will inform a full RCT and future scale-up.

Significance:

Results will provide necessary knowledge to inform how to improve uptake of physical activity recommendations in ways that are sensitive to the health needs of older adults and their life context.
