Promotion of Physical Activity by Health Professionals (PROMOTE-PA) : Protocol for effectiveness outcomes in a hybrid type I effectiveness-implementation cluster randomised controlled trial

Promotion of physical activity by health professionals can increase physical activity participation among patients, however, implementing physical activity promotion within hospital systems is lacking. The Promotion of Physical Activity by Health Professionals (PROMOTE-PA) study is a hybrid type I effectiveness-implementation cluster randomised controlled trial evaluating the effectiveness of support for physical activity promotion by health professionals on physical activity participation of patients. Health professionals delivering outpatient healthcare services within four local health districts and one specialty health network in New South Wales, Australia will be included. The target patient population is children (5–17 years) and adults (18+ years) who are willing to receive additional support to be more physically active. The evidence-based intervention is brief physical activity promotion informed by the ‘5As’ physical activity counselling model and behavioural theory, embedded into routine clinical practice. Our multi-faceted strategy to support implementation of physical activity promotion was developed based on preliminary research and consultation with key stakeholders. The implementation strategy includes education and training as well as a selection of the following (tailored to each clinical team): community referral strategies, experts and clinical mentors, and clinical champions. 30 outpatient clinical teams will be randomised to receive the implementation strategy immediately or after a 3-month delay (waitlist control). Each team will seek to recruit 10–30 patients (n=approx. 720) to report moderate-vigorous physical activity (minutes per week, primary outcome), frequency of balance and strength exercise, mobility, and quality of life at baseline, 3-month and 6-month post patient recruitment. This study aims to address the increasing burden of physical inactivity in a high-risk population using the existing health workforce.
