Summary

This randomized controlled study aims to investigate whether, during a painful medical procedure in an emergency department (ED), the diffusion of a virtual environment through a virtual reality (VR) headset worn by the patient has a greater impact on the patient's pain and anxiety levels than the diffusion of an identical environment through a computer screen. The study design allows differentiating the impact of the medium from that of the media. The feeling of telepresence of patients in both groups and its association with the impact of the medium will also be investigated. In addition, this study aims to explore whether the wearing of VR headphones is considered comfortable and acceptable by patients.

Detailed description

Consultation in a hospital ED and the provided treatments are stressful, as it usually results from an unexpected event that has a negative impact on health. Also, an ED is a noisy and chaotic environment, which can increase anxiety and pain sensitivity related to certain medical procedures. Indeed, the conditions under which medical and surgical procedures are performed have an impact on the patient's experience: pain can be more intense if the patient is stressed and focused on the medical procedure. The well-being of patients, especially during these invasive medical procedures, can be improved by adjusting the conditions in which the procedure is performed. The literature and clinical observations show that distraction is a very effective non-pharmacological strategy to reduce pain and anxiety. The use of measures such as television, music or other audiovisual media has been shown to decrease pain during painful medical procedures in ED. The perception of pain competes with other stimuli, whether sensory or psychological. This competition is all the more effective as the number of senses involved and their intensity increases. However, these traditional media have little distractive power. They capture partially the patient's attention and the patient can easily refocus on the ongoing medical procedure. These traditional media do not produce an immersive experience. According to this principle, the analgesic effect of VR is expected to be greater than that provided by passive distractions such as watching a film on television, as demonstrated during wound dressing replacement in burned patients. Also, the patient's emotional state plays a role in her/his distractibility during a procedure. Therefore, the ideal distractive method should involve a maximum of senses (vision/hear/touch/...) and affects the patient's emotions to compete with the unpleasant stimulus. VR is a recent technology that offers a multi-sensory (vision, hearing), immersive and three-dimensional experience. It offers an active immersion in a virtual world, letting the patient navigate in a virtual world, leading to a greater perceived presence in this virtual environment (telepresence). Telepresence allows the patient to be a co-constructor of the experience. It differentiates VR from other cognitive and distractive techniques. VR can thus distract patients more effectively from the conditions under which they receive their treatment by procuring a superior distraction. However, studies on the impact of VR during invasive or painful procedures have left some unanswered questions that limit its unrestricted use in the ED : * Most of the studies have been conducted in children. * Different technologies have been used by different studies, precluding direct comparisons between studies; * There are few data on the impact of VR applied in an emergency department with adult patients; * The differentiation between the effect of the media (images used) and the effect of the medium (technology used) is often neglected; In this study, the investigators will attempt to demonstrate the potential superiority of VR, using a commercial VR device projecting a virtual environment designed specifically for medical use by a private company, and available to any group or ED wishing to apply this technology. The investigators will include adult patients requiring a painful medical procedure. In addition, patients will be randomized between two groups, both exposed to the same virtual environment (media) but screened in two different technologies (medium).
