In people with heart disease, insufficient physical activity is an independent risk factor for all-causes of death. Within cardiac rehabilitation, people with heart disease are encouraged to meet the physical activity guidelines. Yet clearly, an innovative and effective physical activity intervention is needed in these programs. The research team’s preliminary work has found that regular physical activity measurement by health professionals alone can drive physical activity adherence in insufficiently active adults. However, the optimum frequency of measurement in cardiac rehabilitation is unknown.

A collaboration between the Â鶹´å of Canberra, Queensland Â鶹´å of Technology, the Australian National Â鶹´å, the Â鶹´å of Sydney and Monash Â鶹´å, the Measure It! trial led by Associate Professor Nicole Freene, has been awarded a $510,070 grant under the 2021 Medical Research Â鶹´å Fund (MRFF) Cardiovascular Health Mission scheme. Trial partners include the Australian Cardiovascular Health and Rehabilitation Association, Calvary Public Hospital Bruce, Southern NSW Local Health District, Healthscope Ltd and the Macquarie Health Corporation.

‘Measure It!’ is a very brief intervention, taking clinicians less than 5 minutes to complete. It includes a self-report and objective measure of physical activity (wearable activity tracker steps) plus physical activity advice. The trial will test two frequencies of physical activity measurement (2 and 5 measurements in total) by cardiac rehabilitation clinicians over 24-weeks. This hybrid effectiveness-implementation trial will recruit 190 insufficiently active cardiac rehabilitation attendees from 5 cardiac rehabilitation programs in the Australian Capital Territory and New South Wales. Daily minutes of accelerometer moderate-to-vigorous physical activity will be the primary effectiveness outcome. Implementation outcomes will include acceptability, appropriateness, adoption, costs and sustainability.

The 2-year Measure It! trial will begin in February 2023. Findings from this trial will inform future health service delivery, potentially leading to a highly scalable, low cost, efficient and effective intervention to increase cardiac rehabilitation attendees’ physical activity levels.
