QR Code-Based Video-Supported Anesthesia Information and Preoperative Anxiety

This study aims to evaluate the effects of QR code-based video-supported anesthesia information on preoperative anxiety, comprehensibility of information, and patient satisfaction in adult patients undergoing elective surgery.

Participants will be randomly assigned in a 1:1 ratio to either a control group receiving standard written informed consent and routine verbal anesthesia information or an intervention group receiving the same standard information plus a standardized video-based educational intervention accessed through a QR code.

The primary outcome is the change in the Amsterdam Preoperative Anxiety and Information Scale (APAIS) anxiety score before and after the information process. Secondary outcomes include comprehensibility of information and patient satisfaction assessed using a structured Likert-type questionnaire.

The findings may contribute to the standardization of patient information processes in anesthesia outpatient clinics through a low-cost and easily implementable digital educational approach.
