Screening While You Wait: An Intervention to Facilitate Exercise in Primary Care

The study will take place at the academic Women's College Hospital (WCH) Family Practice (FP) in Toronto, Canada. The clinic provides over 50,000 patient visits per year and is split into four sub-teams for operational purposes. These teams have unique members with no crossover of PCPs. Patients typically see their own PCP for planned care visit (e.g., preventative care and chronic disease management) but access any PCP available when more acute issues arise.

The PA surveys are administered via Ocean by CognisantMD. Ocean connects patients, PCPs, and researchers using secure surveys on tablets in the FP waiting room and online patient surveys that integrate with WCH FP Electronic Medical Records.

This is a pilot step wedge trial, with graduated, random intervention roll-out across the clinical setting in four steps over five time intervals. Eligible patients presenting to the clinic during the study period will be allocated to intervention or control depending on whether the PCP they have booked to see has had the intervention 'turned-on'. The order determining when each PCP and his or her team change from control to intervention is randomly assigned. This design was chosen to avoid the risk of intervention contamination and to enable logistics of implementation. The teams will receive the control and intervention according to the following schedule:

Time Interval 1: Team A-D Control Time Interval 2: Team A Intervention, Team B-D Control Time Interval 3: Team A+B Intervention, Team C+D Control Time Interval 4: Team A-C Intervention, Team D Control Time Interval 5: Team A-D Intervention

Family physicians (and the patients they care for) are eligible for the study if they are active staff at WCH FP and have consented to participating.

Participating family physicians will assist in identifying potential participants and confirm that patients are appropriate participants for a study of this nature.

Patient inclusion criteria:

• Adult WCH FP patients aged 18-79
• Attending a PHR - formerly known as a 'complete physical' examination

Patient exclusion criteria:

• Non-English speaking patients (due to inability to translate the study materials at the pilot-phase)
• Patients with dementia or cognitive impairment (due to the burden of completing survey materials potentially outweighing the uncertain benefit of intervention)
• Patients who have a major ongoing illness (due to the possibility of their injury/illness interfering with their PA capabilities)
• Patients who are pregnant (due to limitations in modifying PA level between baseline and follow-up)
