A comparison of face-to-face, brochure- and video-assisted anesthesia interviews: a qualitative randomized survey study.

Background: Previous studies showed mixed results for patient satisfaction by supplementing the preanesthetic assessment with written or audio-visual materials. We hypothesize that an audio-visual aid or a brochure in addition to face-to-face interview, leads to improved patient satisfaction and shortens the preanesthetic assessment duration.

Methods: We randomly assigned 1051 patients scheduled for preanesthetic assessment to three different groups: face-to-face preanesthetic interview alone (Group 1), videos before the interview (Group 2), and brochure before the interview (Group 3).
