The Effectiveness of a Virtual Reality-based Educational Intervention on Anxiety Symptoms, Pain Levels, and Physiological Indicator Outcomes in Surgical Patients
Sponsor: Jia-Ling Wang
Summary
Study Design and Participants This study employed a prospective, randomized controlled trial (RCT) design. A total of two study arms were established: an experimental group receiving a virtual reality (VR) education intervention combined with conventional care, and a control group receiving a unit health education film with conventional care. Participants were recruited based on the following inclusion criteria: adults aged 18 years or older scheduled for elective hip or knee replacement surgery under spinal anesthesia; an American Society of Anesthesiologists (ASA) physical status grade of I to III; clear consciousness with the ability to read and understand Chinese; and no prior diagnosis of anxiety disorders or significant visual/hearing impairments. Patients were excluded if they had a history of head trauma or chronic dizziness, or if they required post-operative transfer to the intensive care unit (ICU) due to medical complications. Randomization and Intervention Eligible participants were assigned to either the experimental or control group using block randomization to ensure balanced group sizes. The primary intervention for the experimental group consisted of a structured Virtual Reality Education Program, while the control group received standard institutional health education via video. Data Collection and Instrumentation A repeated-measures approach was utilized for data collection across four distinct time points: (1) baseline (one day prior to surgery), (2) pre-operative arrival at the operating room holding area on the day of surgery, (3) one day post-operatively, and (4) three days post-operatively. The research instruments used for assessment included: A demographic profile sheet. The State-Trait Anxiety Inventory (STAI). The Visual Analogue Scale for Anxiety (VAS-A). The Visual Analogue Scale for Pain (VAS-P). A Virtual Reality Education Satisfaction Questionnaire. Standardized physiological indicators.

Virtual reality
Intervention Name: Virtual Reality-Based Preoperative Education Intervention Description: A 10-15 minute immersive virtual reality (VR) education program administered via a head-mounted display (HMD) one day prior to surgery. The simulation provides a 360-degree interactive walkthrough of the operating room environment and the spinal anesthesia procedure (including patient positioning and sensory expectations). This intervention aims to reduce preoperative anxiety through high-fidelity sensory immersion. It is provided in addition to standard conventional nursing care.
Conventional Video
Intervention Name: Conventional Health Education Video Intervention Description: A 10-15 minute standard health education video delivered via a tablet or television screen one day prior to surgery. The video content is identical to the experimental group, covering the surgical environment, spinal anesthesia steps, and post-operative recovery exercises, but presented in a traditional 2D, non-immersive format. This group represents the current standard of care for preoperative education at the clinical site.
