Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Physical activity measurement (PAM) intervention: ‘Measure It!’ includes a self-report and objective measure of physical activity plus physical activity advice provided by their cardiac rehabilitation clinician. Patients will be asked about their current level of physical activity using the Physical Activity Vital Sign (On average how many days per week do you engage in moderate or greater physical activity?; On average how many minutes per day do you engage in activity at this level?), taking less than 30 seconds to complete. Patients will also be asked to provide the average number of steps/day they completed in the last week according to their wearable activity tracker or smartphone app. The physical activity guidelines will be very briefly discussed (2 minutes) at each measurement. An example of the very brief physical activity advice provided is ‘moderate intensity physical activity means you should be able to talk in full sentences but not sing’, or ‘any activity is better than none’. Patients will be encouraged to safely increase their physical activity levels during the 24-week intervention period aiming to progress towards the Australian Physical Activity and Sedentary Behaviour Guidelines for Adults, that is, accumulate 150 to 300 minutes of moderate intensity physical activity or 75 to 150 minutes of vigorous intensity physical activity or a combination of both each week. The ‘Measure It!’ intervention will be delivered face-to-face at baseline (5-PAM), 6 (5-PAM, end-cardiac rehabilitation program) and 24-weeks (5-PAM) but may be delivered via telehealth at 12 (5-PAM) and 18-weeks (5-PAM) depending on the site-specific cardiac rehabilitation model. The number of times the intervention is delivered to each patient will be recorded. From our pilot study (ACTRN12616000566437) in a healthy adult population, the total time required for measuring physical activity and provision of brief advice was less than 5 minutes, classifying this as a very brief intervention.

Comparator / control treatment
The comparator group will receive 2 physical activity measurements face-to-face over 24-weeks (2-PAM: baseline and 24-weeks) compared to 5 physical activity measurements (5-PAM) over 24-weeks in the intervention group. The intervention for the comparator group is the same as the intervention group but at a lower frequency over the 24-week period. The number of times the intervention is delivered to each patient in the 2-PAM will be recorded.

Outcomes
Primary outcome [1] 332158 0
Physical activity levels: A triaxial commercial accelerometer (ActiGraph GT3X, Fort Walton Beach, FL) will be used to objectively assess physical activity. Patients will be asked to wear the accelerometer on their right hip, while awake, for 7-consecutive days at baseline and 24-weeks as an outcome measure only, returning the accelerometer via mail in the reply-paid post pak provided. All data will be downloaded, screened and categorised according to commonly used algorithms in this population to determine time spent in different physical activity intensities.
Timepoint [1] 332158 0
For a 7-day period at baseline and 24-weeks post-commencement of intervention.
Secondary outcome [1] 412417 0
Health-related quality of life: The Assessment of Quality of Life (AQoL)-6D is a self-administered health-related quality of life questionnaire. It has 20 items, takes 2-3 minutes to complete, and has six dimensions - independent living, mental health, coping, relationships, pain, senses, and provides an overall multi-attribute utility score.

Baseline and 24-weeks post-commencement of intervention.
Secondary outcome [3] 412419 0
Waist circumference: Waist circumference will be measured in centimetres using a stretch-resistant tape measure. The waist circumference will be recorded as the midpoint between the lower margin of the lowest palpable rib and the top of the iliac crest. The measure will be repeated twice.
Timepoint [3] 412419 0
Baseline and 24-weeks post-commencement of intervention.
Secondary outcome [4] 412420 0
Cardiac rehabilitation clinicians physical activity promotion survey: Cardiac rehabilitation clinicians will be asked to complete an online survey which includes questions about their physical activity promotion practices, perceived role in physical activity promotion, barriers to promotion, feasibility of different strategies, knowledge of the physical activity guidelines and personal physical activity levels using a validated survey.
Timepoint [4] 412420 0
Baseline and 18-months post-commencement of intervention.
Secondary outcome [5] 412424 0
Costs (healthcare perspective): Healthcare resource use will include trial-intervention resource use (e.g. cardiac rehabilitation clinician’s time) and non-trial healthcare use which may be impacted (e.g. hospital visits via an audit of hospital records; Medicare and PBS items from Services Australia, where patients have consented to access), costed using actual costs accrued where available or market rate estimates.
Timepoint [5] 412424 0
24-weeks post-commencement of intervention.
Secondary outcome [6] 413464 0
Acceptability of the Intervention: Patients and cardiac rehabilitation clinicians will be asked about the acceptability of the intervention using the Acceptability of Intervention Measure (AIM), a valid and reliable scale, which will be electronically-administered following an interview with consenting patients and cardiac rehabilitation clinicians.
Timepoint [6] 413464 0
Patients: 24-weeks post-commencement of intervention.
Cardiac rehabilitation clinicians: 18-months post-commencement of intervention.
Secondary outcome [7] 413465 0
Implementation outcome (acceptability, appropriateness, adoption, sustainability and feasibility): Semi-structured interviews will be conducted with patients and treating cardiac rehabilitation clinicians. The Consolidated Framework for Implementation Research (CFIR) and the Theoretical Domains Framework (TDF) will be used to understand how the physical activity intervention works to change individual behaviour and multilevel factors that influence implementation success or failure. Interviews will be led by an experienced qualitative researcher post-intervention. All interviews will be audio-recorded and professionally transcribed. The implementation outcome is a composite measure of acceptability, appropriateness, adoption, sustainability and feasibility.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
After patient baseline measures have been completed, the investigator will be contacted via telephone or email by the assessing cardiac rehabilitation clinician to reveal random allocation to one of two groups (1:1 ratio): 5 physical activity measurements (5-PAM) or 2 physical activity measurements (2-PAM) in total over 24-weeks.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
An investigator in a remote location and not involved in recruitment or assessments will use a computer to generate a random number sequence which is consecutively numbered. Randomisation will occur at an individual patient level.

Statistical methods / analysis
Analyses will be carried out following the intention-to-treat principle. Linear (for continuous outcome data) and generalised linear (for binary and count outcome data) fixed-effects models will be used for between group comparisons at 24-weeks and interactions analyses adjusting for baseline measures as well as demographic characteristics, such as gender, and other potential covariates, such as cardiac rehabilitation program. All analyses will be conducted using either SPSS or STATA. Significance level will be set at p<0.05.

Incremental cost-effectiveness ratios (ICER) of cost (healthcare perspective) per Quality Adjusted Life Year (from AQoL-6D) gained (24-week time horizon, consistent with primary analysis) will be estimated for the between group comparison using patient level trial data, that is, ICER (5 vs 2-PAM) = [(Cost5-PAM)-(Cost2-PAM)] / [(Effect5-PAM-Effect2-PAM)]. Bootstrap resampling will be used to derive 95% confidence intervals (costs and effects) and 95% confidence ellipse (ICER). Probabilistic extrapolation modelling (stochastic, following modelling guidelines informed by best available evidence including trial (e.g. measures of disease risk) and published literature) will extend these estimates to a (secondary) time-horizon of 5-years. Cost-effectiveness acceptability curves will be prepared. We will assess the sensitivity of results to variation in measured resource use, effectiveness, time-horizon, discounting and unit costs.
