Alleviating Pre-operative Anxiety With Innovative 3D Immersive Virtual Reality

Study Overview
=================
Brief Summary
-----------------
To construct and evaluate an immersive 3D simulation to familiarize patients with the pre-operative experience, and investigate whether A) immersive 3D virtual reality video can reduce pre-operative anxiety, and B) how this approach compares to current practice of viewing traditional educational videos.

Detailed Description
-----------------
The prevalence of pre-operative anxiety is estimated as being as high as 80% in surgical populations. Physiologically, this may result in higher cortisol levels, which may slow down the healing and recovery process. A multitude of perioperative clinical trials have revealed that pre-operative anxiety is associated with reduced short-term postoperative recovery, increased pain scores, nause & vomiting, sleep disturbances, surgical wound infections, increased length of stay, and cardiac complications. It has also been linked with worse functional outcomes and quality of life up to one-year after surgery. Literature looking at factors associated with preoperative anxiety outline a general theme of the fear of the unknown that is distressing. Specifically, the most distressing events seem to be waiting to be collected for surgery, waiting outside the operating room (OR), being transferred to the OR bed and having monitors and oxygen mask applied. These moments prior to surgery are when patients are most likely to continuously ruminate over 'what comes next' and the fact of not knowing - leading to anxiety. One survey of 161 patients presenting for elective surgery inquired about factors that led to being calm prior to their procedure and found that being well informed of the pre-operative process was a critical aspect of anxiety relief. Approaches such as implementation of the pre-anesthetic clinic (PAC) and the use of videos of what to expect leading up to surgery have been implemented to address this issue but have been costly or have had mixed effects. Virtual reality (VR) technology presents a new educational opportunity for patients in an effort to reduce pre-operative anxiety. Through immersive 3D simulation, patients can experience the journey of being prepped for surgery and transferred to the OR. A patient can learn about their pre-operative experience in a more engaging manner as opposed to passively reading, watching video or being verbally taught about it by the healthcare provider. A patient is educated by having the perception of being physically present in the pre-operative experience days or weeks prior to their OR date.
