| Summary: | Introduction Physical activity has important benefits for the prevention and management of chronic diseases and healthy ageing. Health professionals have valuable opportunities to promote physical activity to a large group of people across the lifespan. Promotion of Physical Activity by Health Professionals is a hybrid type 1 effectiveness-implementation cluster randomised trial designed to evaluate the impact of physical activity promotion by health professionals (n=30 clusters) on physical activity participation in their patients (n=720). To inform the future implementation of this programme, we will be conducting a within-trial and modelled economic evaluation.Methods and analysis We will conduct a cost-effectiveness and cost-utility analysis from the perspective of the healthcare, aged care and disability funder. The time horizon will be 6 months for the within-trial analysis and 2 years for the modelled analysis. Data on intervention costs will be collected using trial records. Data on healthcare utilisation will be collected using data linkage. Incremental cost-effectiveness ratios (ICERs) will be reported for physical activity and quality-adjusted life years outcomes. Bootstrapping will be used to explore uncertainty around the ICERs and estimate 95% CIs. Results will be presented on a cost-effectiveness plane. The probability that the intervention would be cost-effective at varying willingness-to-pay thresholds will be presented using a cost-effectiveness acceptability curve.Ethics and dissemination Ethics approval was obtained through Sydney Local Health District (RPAH zone) Ethics Review Committee (X23-0197). The findings of this study will be disseminated through peer-reviewed journal articles and conference presentations.Trial registration number Australian New Zealand Clinical Trials Registry: ACTRN12623000920695. |
