Résumé : Objective: To evaluate the impact of a hypnosis or music therapy session on the emotional feeling of hospital staff following the care of the victims of the Brussels attacks in March 2016. Method: This exploratory, prospective, randomized, single-center study was conducted in the intensive care and emergency department of Erasme Hospital. Personal experience is assessed before and after a session of hypnosis or music therapy. Two questionnaires were used: the Maslach Burnout Inventory (MBI) measuring the severity of Burnout Syndrome and the Impact of Event Scale-Revisited questionnaire (IES-R) examining the risk of PTSD emergence. Results Seventy-seven people participated in the hypnosis session (n = 40) or the music therapy session (n = 37). The results showed an improvement in MBI in the hypnosis group for emotional exhaustion: high (50/0 vs. 2.50/0) (p = o.0006); for depersonalization: high (300/0 vs. 200/0) (p = 0.0009); for loss of personal achievement: high (57-50/0 vs. 350/0) (p = o.oooo). The results for the music therapy group also showed an improvement in MBI for emotional exhaustion: high (5-4% vs. 2.70/0) (p = o.008) and for the loss of personal achievement: high (43, 2% vs 270/0) (p = 0.02). The IES-R score decreased significantly in the group: hypnosis: very symptomatic (22.50/0 vs 50/0) (p = 0.0001) and in the music therapy group: very symptomatic (35.10/0 vs 8, 10/0) (p = o.oooo). Conclusion: This study shows that a session of hypnosis or music therapy alleviates the signs of SdEP and PTSD of medical staff exposed to intense stress.
