Virtual Reality–Based Intervention to Reduce Preoperative Anxiety in Adults Undergoing Elective Surgery: A Randomized Clinical Trial
Authors' conclusion
The findings of this study suggest that a VR-based intervention is a feasible and effective way to reduce preoperative anxiety in adult patients undergoing elective surgery.
Study context
- Population
- Adults ≥18 y scheduled for first elective surgery under GA within 2–4 weeks, preanesthesia assessment clinic, Hong Kong, July–December 2022
- Participants
- 74 adults
- Comparison
- Intervention vs Control
- Interventionn = 37
- Controln = 37reference
- Primary endpoint
- Preoperative anxiety (Amsterdam Preoperative Anxiety and Information Scale, range 6-30; higher = greater anxiety)
- Follow-up
- T1 (end of clinical session, immediately after intervention) and T2 (before surgery)
