Impact of hypnosis on patient experience after venous access port implantation

Introduction: Hypnosis has been reported to decrease pain and anxiety in surgical context, but data studying its impact on patient experience using a validated scale are scarce. In the present study, we assessed the effect of an audio hypnosis session on patient satisfaction during venous access port implantation under local anaesthesia in adult cancer patients using the EVAN-LR Score. Methods: After informed consent, patients were randomised to receive either hypnosis or standard care. The hypnosis group listened to a 26 minutes recorded audio hypnosis session through the ongoing implantation procedure. The primary outcome was the result of the EVAN-LR questionnaire, assessing perioperative experience in patients undergoing anaesthesia without loss of consciousness. This score describes a global index and 5 dimensions of experience: comfort, pain attention, information and waiting. It is scaled from 0 to 100 with 100 indicating the best possible level of satisfaction. Secondary outcomes included patient's anxiety, heart rate before and after procedure, procedure duration and several Visual Analogic Scale to match EVAN-LR dimensions. Results: Overall, 148 patients were enrolled in the study. The global index of Evan-LR was significantly higher in the hypnosis session group (78 ± 14) compared to the standard care group (71 ± 17) (P = 0.006). No difference was reported in secondary outcomes. Conclusion: A recorded audio hypnosis session during subcutaneous venous port implantation under local anaesthesia in cancer patients significantly improved patient satisfaction.
