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

Elazıg Fethi Sekin Sehir Hastanesi284 enrolled

Overview

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.

Informed consent and preoperative patient education are essential components of perioperative care. However, written consent forms may be difficult for some patients to understand because of technical language, limited consultation time, and variability in verbal explanations. Digital educational tools may provide standardized and more comprehensible information before surgery. This single-center, prospective, parallel-group randomized controlled trial will evaluate whether QR code-based video-supported anesthesia information improves preoperative patient education compared with standard written informed consent and routine verbal anesthesia information. Adult patients scheduled for elective surgery will be randomized in a 1:1 ratio to either standard information alone or standard information plus access to a standardized educational video via QR code. The video-supported intervention is designed to provide clear visual and auditory information about the anesthesia process, preparation before surgery, perioperative care, potential complications, common temporary side effects, patient rights, and the importance of informed consent. The study will assess whether this approach reduces preoperative anxiety and improves patients' understanding of anesthesia-related information and satisfaction with the information process.

Outcomes

Primary Outcomes

Change in APAIS Anxiety Score

Change in the Amsterdam Preoperative Anxiety and Information Scale (APAIS) anxiety subscale score from before the information process (T1) to after completion of the information process (T2). The APAIS anxiety subscale ranges from 4 to 20, with higher scores indicating greater preoperative anxiety.

Time frame: Immediately before and immediately after completion of the information process (same study visit)

Secondary Outcomes

Information Comprehensibility Score

Comprehensibility of anesthesia information assessed using a structured 10-item Likert-type questionnaire. Total scores range from 10 to 50, with higher scores indicating better understanding and comprehensibility of the information provided.

Time frame: Immediately after completion of the information process

Patient Satisfaction Score

Patient satisfaction with the anesthesia information process assessed using a structured 10-item Likert-type questionnaire. Total scores range from 10 to 50, with higher scores indicating greater satisfaction with the information process.
