Preoperative anxiety is common among patients undergoing elective surgery and may negatively affect perioperative outcomes. This randomized controlled trial aims to evaluate the effectiveness of a short educational video in reducing preoperative anxiety. Participants will be assigned to one of three groups: a QR code-based video group, a tablet-based video group, or a control group receiving standard preoperative information. Anxiety levels will be assessed using the Amsterdam Preoperative Anxiety and Information Scale (APAIS). The secondary objective is to evaluate the utilization of QR code-based video education.
