Randomized Controlled Trial Clinical TrialA randomized trial using videotape to present consent information for colonoscopy.
A randomized controlled trial was conducted to determine if a videotaped presentation by a physician conveys information more effectively than an in-person discussion by the same physician using the identical script. Two hundred one patients undergoing colonoscopy were enrolled in the study. Patients were randomly assigned to one of three groups: video plus discussion, video alone, and discussion alone. ⋯ No difference was noted between the two video groups (p = 0.32). Anxiety did not increase with increased understanding of the risks and benefits of colonoscopy. This approach may work as well for other invasive medical procedures and could save physician time while laying a foundation for a more personalized discussion.
