Atmospheric Projection in the Emergency Department

NCT05967988 | Terminated DMC

• 1 other identifier: CER-VD 2023-00867
• Study Type: interventional
• Target: 62

Brief Summary

The goal of this clinical trial is to learn about the reduction of pain and anxiety during a minor procedure in the emergency department on adult patients through the visualisation of atmospheric projection as a distraction mean. The main question it aims to answer is : 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

Outcome Measures

Primary Outcomes (2)

• 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"

  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."

  Just after the procedure

Secondary Outcomes (8)

• Telepresence

  Just after the procedure

• Dissociation

  Just after the procedure

• Appreciation of the atmospheric projection

  Just after the procedure

• Patient's comfort

  Just after the procedure

• Procedural support

  After the procedure
