Virtual Reality Tour to Reduce Perioperative Anxiety in an Operating Setting Before Anesthesia: Randomized Clinical Trial.

Background: Perioperative anxiety is a major burden to patients undergoing surgeries with general anesthesia.

Objective: This study investigated whether a virtual operating room tour (VORT) before surgery can be used to ameliorate perioperative anxiety.

Methods: We employed a randomized parallel-group design with 2 study arms to compare VORT to the standard operation preparation procedure.
