Cancer Clinical Trial

Official title: Randomized Controlled Study Evaluating the Efficacy of Hypnosis by Deportee Method Adapted to Nuclear Medicine

Status Recruiting

Clinical Trial Summary

In Nuclear Medicine, the examinations are long (20-60 minutes) and the patients must remain immobile, sometimes fasting. The anxiety of the latter can lead to poor quality examinations and sometimes, although already injected with radioactive drugs, the patients refuse the examination. In imaging, the use of hypnosis (prior to the MRI examination or with the patient during a scintigraphic examination) is frequent due to the conformation of MRI or scintigraphic machines, particularly for claustrophobic patients (2-2.5% of cases).

Medical electroradiology manipulators (MERM) have been trained to practice Ericksonian hypnosis whose effectiveness in combating anxiety is no longer in question. Scientific studies by Faymonville et al, 2006 and Rainville et al, 2002, have shown the effectiveness of this method in managing anxiety using the simplified STAI-6 scale before and after hypnosis.

The dosimetric study of the MERM position would then be greatly modified in favor of a decrease in exposure targeted by the June 4, 2018 decree on personnel safety. The impact of whether or not the MERM is physically present near the patient would also be studied. If minimal, this will resolve the current contradiction between the quality of patient care delivered and the radiation protection imposed in nuclear medicine.

The investigators propose here a pilot study evaluating remote-delivered Ericksonian hypnosis versus conventionally-delivered Ericksonian hypnosis, which will allow for the sizing of a subsequent multicenter randomized non-inferiority controlled trial. Indeed, there is currently no data available on the non-inferiority margin of this technique.

Clinical Trial Description

In Nuclear Medicine, the examinations are long (20-60 minutes) and the patients must remain immobile, sometimes fasting. The anxiety of the latter can lead to poor quality examinations and sometimes, although already injected with radioactive drugs, the patients refuse the examination. In imaging, the use of hypnosis (prior to the MRI examination or with the patient during a scintigraphic examination) is frequent due to the conformation of MRI or scintigraphic machines, particularly for claustrophobic patients (2-2.5% of cases).

Medical electroradiology manipulators (MERM) have been trained to practice Ericksonian hypnosis whose effectiveness in combating anxiety is no longer in question. Scientific studies by Faymonville and Rainville have shown the effectiveness of this method in managing anxiety using the simplified STAI-6 scale before and after hypnosis.

During nuclear medicine examinations, the proximity of MERMs to patients to practice conventional hypnosis results in significant exposure to radioactive radiation, which is not compatible with radiation protection guidelines. Some MERMs have been practicing hypnosis for several years, others are reluctant. However, exposure decreases as a function of the decrease in exposure time and the distance to the radioactive source. If the examination time cannot be modified, the distance to the patient could be by using an original method, remote hypnosis using a headset and microphone to provide Ericksonian hypnosis sessions in the same way as those provided in conventional sessions. The dosimetric study of the MERM position would then be greatly modified in favor of a decrease in exposure targeted by the June 4, 2018 decree on personnel safety. The impact of whether or not the MERM is physically present near the patient would also be studied. If minimal, this will resolve the current contradiction between the quality of patient care delivered and the radiation protection imposed in nuclear medicine.

The investigators propose here a pilot study evaluating remote-delivered Ericksonian hypnosis versus conventionally-delivered Ericksonian hypnosis, which will allow for the sizing of a subsequent multicenter randomized non-inferiority controlled trial. Indeed, there is currently no data available on the non-inferiority margin of this technique. This pilot study will also allow for extensive documentation of the implementation of the remote hypnosis technique and for any necessary adjustments to the intervention to ensure its feasibility, acceptability, and reproducibility in the subsequent trial.

The hypothesis is that the use of remote-assisted hypnosis in nuclear medicine reduces patient anxiety as much as conventional Ericksonian hypnosis, while limiting the radiation exposure of the MERMs. ;
