Implementing an Evidence-based Exercise Program to Reduce Falls in Community-dwelling Older Adults (Otago)

Implementing an Evidence-based Exercise Program to Reduce Falls in Community-dwelling Older Adults

Falls are a major health care problem for seniors. The Otago Exercise Program, which consists of strength and balance training delivered by a physiotherapist, can reduce falls in this population. We will test two methods to deliver the Otago program. These will include a new coaching approach by a physiotherapist with the use of a Fitbit to provide feedback versus the traditional delivery. The degree to which the program is delivered as intended by physiotherapists as well as the number of falls, risk of falling, and participation in walking activities in older adults will be assessed over 24 months. Lastly, we will assess if the coaching approach is a cost-effective option.

Falls are a major health care problem for older adults (i.e., those aged ≥ 65 years) and health care systems. Falls account for 50% of injury-related admissions to hospital, 40% of admissions to nursing homes, and a 10% increase in home care services. They are also the leading cause of fatal injury among Canadians over 65 years old. This represents a significant health burden. Fortunately, falls are preventable. There is strong evidence that the Otago Exercise Program (OEP), physiotherapist (PT)-led home-based exercise program of strength and balance training, is effective at preventing falls in older adults with complex medical conditions. Originally developed in New Zealand the OEP has been implemented worldwide, but adherence to the program is a challenge. We propose that the suboptimal adherence is partly due to a lack of focus on behaviour change techniques such as self-monitoring and action planning in the delivery of OEP.

The investigators will use a mixed-methods approach, involving a RCT and in-depth interviews. The delivery of OEP+ vs OEP, from PTs, and its recipients, the older adults, will be determined at random. The training for the PT's will be provided by the Centre for Collaboration Motivation & Innovation (CCMI), a non-profit organization with a mandate to support the use of behaviour change techniques to improve health care. Prior to data collection, the PTs will attend a 2-hour workshop on the coaching protocol using the OEP app.

The goal of this project is to assess OEP+ as an implementation strategy to improve OEP delivery (by PTs) and adherence (by older adults).
