Augmented Reality (AR) Soothes Pre-Surgery Anxiety in Patients

Researchers from the University of Miami specializing in medicine and computer science have discovered that utilizing Augmented Reality (AR) to guide patients through a surgical procedure lowers anxiety. Before starting an orthopedic treatment, the team fitted patients with AR equipment in their trial. The outcomes of this study, relative to the anxiety levels of a control group, were published in JAMA Network Open.

Prior studies have revealed that the majority of people feel some level of anxiety while getting ready for surgery. The fear of the unknown and the dread of being cut open, which was the obvious cause of some stress, are present. Also, most people do not undergo surgery frequently, so they are unsure of what to expect.

Scientists have been exploring methods to assist patients in order to alleviate certain aspects of their anxiety. One such method that has shown some potential is to have them participate in a virtual reality practice session. VR, however, is a passive activity. The researchers’ goal with this new effort was to see if employing AR may be a superior strategy.

To find out, the research team invited 140 patients scheduled for elective, outpatient orthopedic surgery to participate in an AR experiment. Of those, 95 individuals underwent the AR experience after 45 patients were disqualified.

The volunteers were divided into two groups:

• Those who received just the usual pre-operative instructions
• Those who also received a three-minute augmented reality experience narrated by the surgeon who would conduct their surgery

At various stages during their participation, all the volunteers were asked twice before and twice after the procedure how anxious they felt.

Comparing individuals in the AR group with those in the control group, the researchers discovered that people in the AR group reported reduced stress and anxiety levels.

The research team thus concluded that AR can be an effective tool for lowering pre-op stress and anxiety. However, they also point out that additional research is needed to see if it is equally helpful in more widespread situations.
