About this study

Official title: AtmosphEric pRojection for paIn and Anxiety reLated to Minor Medical Procedures in the Emergency Department: a Monocentric, Parallel, Randomized, Controlled Study

Can the atmospheric projection of a video reduce pain and anxiety in adult patients receiving painful procedures in the emergency department ?

Participants will look at an atmospheric projection (projection of a media on the walls and roof around the patient) while receiving their planned care procedures. Researchers will compare an active group watching a video with a control group watching a simple colored light to see if the visualisation of an atmospheric projected video reduces pain and anxiety more than the visualisation of a colored light does.

Conditions: Pain, Acute, Anxiety Acute
Being tested: Immersive atmospheric projection, Minimal atmospheric projection
Medical subject headings: Acute Pain

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Immersive atmospheric projectionDevice
Projection of computer-generated videos or videos of real moving landscapes on the walls of the examination room

Projection of a colors on the walls on the walls of the examination room

Study groups in NCT05967988
Study group	Role	What they receive
Atmospheric 3D video projection	Experimental	Patients in the interventional arm will watch an immersive atmospheric video projection on the walls of their examination room. Receives: Device: Immersive atmospheric projection
Atmospheric 3D color projection	Sham comparator	Patients in the interventional arm will look at a neutral color of their choice projected on the walls of their examination room. Receives: Device: Minimal atmospheric projection

What is being measured

The primary outcome is the main question the study is designed to answer.

Procedural Pain
Maximal pain intensity experienced by the patient during the medical procedure, assessed using a Visual Analogic Scale from 0mm to 100mm anchored with "No pain/Worst pain imaginable"
Measured: Just after the procedure
Procedural Anxiety
Maximal anxiety intensity felt by the patient during the medical procedure, assessed using a Visual Analogic Scale from 0mm to 100mm anchored with "Not at all anxious/Extremely anxious."
Measured: Just after the procedure

Secondary outcomes (8)

Telepresence
Telepresence will be assessed by the Igroupe Presence Questionnaire composed of 14 statements grouped into 4 categories: (1) spatial presence (the sense of being physically present in the virtual environment), (2) involvement (attention devoted to the virtual environment and experienced involvement), (3) experienced realism (the subjective experience of realism in the virtual environment), and (4) the general sense of being in the virtual environment. Each question is rated on a 7-point scale (0 to 6), with greater scores indicating a greater sense of presence in the projected environment
Measured: Just after the procedure
Dissociation
Dissociation of the patients represents the mental separation of the patient from their environment, assessed using a Visual Analogic Scale from 0mm to 100mm, anchored with "most present in the clinical environment / the most immersed in the projected environment "
Measured: Just after the procedure
Appreciation of the atmospheric projection
Appreciation of the atmospheric projection by the patient, using a Visual Analogic Scale from 0mm to 100mm, anchored with "least appreciative/most appreciative)
Measured: Just after the procedure
Patient's comfort
Patient's comfort during the atmospheric projection, assessed using a Visual Analogic Scale from 0mm to 100mm, anchored with "least comfortable /most comfortable"
Measured: Just after the procedure
Procedural support
Procedural support provided by the projection during the medical procedure according to the physician in charge of the procedure, assessed using a 3-level Likert scale (yes-neutral-no)
Measured: After the procedure
Procedural disturbance
Procedural disturbance for physicians caused by the atmospheric projection interfering with the medical procedure, assessed using a 3-level Likert scale (yes-neutral-no)
Measured: Just after the procedure
Cybercinetosis
Cybercinetosis is a symptom similar to motion sickness that occurs with exposure to a virtual environment, will be assessed using a 3-level Likert scale (light-moderate-severe)
Measured: Just after the procedure
Pain catastrophizing
Pain catastrophizing will be assessed using the French version of the Situational Catastrophizing Questionnaire, a 6-question adaptation of the Pain Catastrophizing Scale
Measured: Just before the procedure
