Intervention Schematic. Members of each mentor-mentee pod met in person at least once within the first 3 months of the start of the intervention, and the subsequent frequency and nature of mentor-mentee interactions was determined by participants themselves. However, mentors were asked to initiate contact with each mentee at least once every 3 months if no contact was ongoing. Brief educational videos (each featuring a mentor) and spirometry cases with corresponding questions were emailed to mentees and posted to the online portal every 4–6 weeks, to encourage mentor-mentee interaction. Mentors posted correct answers 1 week after each case was first posted. All users were also provided with access to the Ontario Lung Association’s (OLA) online spirometry-related educational resources throughout the intervention period (available at www.on.lung.ca)
