Implementation of interventions
The interventions were displayed to participants within the survey platform. To encourage attention to the intervention, a timer was added to the pages displaying the Video (3 min) and 5 Questions resource (1 min), preventing participants from progressing to the next survey page until the specified time had elapsed. For those receiving both interventions, the Video was presented before the Choosing Wisely Questions. Participants were not prevented from exposure to any other care or interventions prior to or during the study.
