Effect of a Preoperative Educational Video on Anxiety Levels

Effect of QR Code-Based and Tablet-Based Preoperative Educational Video Interventions on Preoperative Anxiety

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.

Preoperative anxiety is associated with adverse psychological and physiological responses and may negatively influence the perioperative experience. Educational interventions have been proposed as a practical strategy to improve patient understanding and reduce anxiety before surgery. Video-based education offers a standardized and accessible method for delivering information regarding anesthesia and surgical procedures.

Recent advances in digital health technologies have facilitated the use of mobile devices and QR code-based educational tools in routine clinical practice. However, evidence regarding the effectiveness of different modes of video delivery on preoperative anxiety remains limited.

This study will evaluate whether a brief educational video delivered through a QR code before the day of surgery or viewed on a tablet device immediately before surgery can reduce preoperative anxiety compared with standard care. In addition, the study will assess the feasibility and utilization of QR code-based patient education in the perioperative setting. The findings may contribute to the development of accessible and scalable patient education strategies aimed at improving the surgical experience and patient-centered care.
