QR Code-Based Video-Supported Anesthesia Information and Preoperative Anxiety (QR-AID)

The Effect of QR Code-Based Video-Supported Anesthesia Information on Preoperative Anxiety, Comprehensibility of Information, and Patient Satisfaction: A Prospective Randomized Controlled Study

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.

Study Overview

• Status: Not yet recruiting
• Conditions: Preoperative Anxiety; Anesthesia; Informed Consent; Patient Education
• Intervention / Treatment: Behavioral: QR Code-Based Video-Supported Anesthesia Information

Detailed Description

Background:

Informed consent and patient information 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 variations in verbal explanations provided by clinicians. Digital educational tools may improve patient understanding and reduce preoperative anxiety by providing standardized information.

Objective:

The primary objective of this randomized controlled trial is to determine whether QR code-based video-supported anesthesia information reduces preoperative anxiety compared with standard written and verbal information alone.

Methods:

This is a single-center, prospective, parallel-group randomized controlled trial conducted at Elazig Fethi Sekin City Hospital.

Adult patients scheduled for elective surgery will be screened for eligibility and randomized in a 1:1 ratio to either:

1. Control Group:

   Standard written informed consent and routine verbal anesthesia information.

2. Intervention Group:

Standard written informed consent and routine verbal anesthesia information plus a standardized video-based educational intervention delivered through a QR code and viewed using a tablet device and headphones.

The educational video includes information regarding:

• Purpose of anesthesia
• Types of anesthesia
• Preoperative fasting requirements
• Preparation for surgery
• Perioperative process
• Potential complications
• Common temporary side effects
• Patient rights
• Meaning and importance of informed consent

Outcomes:

Primary Outcome:

Change in Amsterdam Preoperative Anxiety and Information Scale (APAIS) anxiety score measured before and after completion of the information process.

Secondary Outcomes:

• Comprehensibility of information
• Patient satisfaction

Both secondary outcomes will be assessed using a structured 10-item Likert-type questionnaire.

Expected Impact:

This study will evaluate whether a standardized QR code-based video education model can improve patient understanding, reduce anxiety, and increase satisfaction. If effective, the intervention may provide a scalable and low-cost strategy for standardizing anesthesia information processes in routine clinical practice.
