Evaluation of the Efficacy of E2R Hypnotherapy in the Management of Chronic Insomnia in Primary Care (HypERR)

In France, the treatment of chronic insomnia relies mainly on hypnotic drugs in routine care, despite the high level of iatrogenicity. Cognitive-behavioral therapy (CBT) is recommended by the HAS as a non-pharmaceutical first-line therapy for chronic insomnia. Despite evidence of their efficacy in chronic insomnia, these therapies remain underdeveloped in France (few practitioners, time-consuming for the patient). Hypnotherapy is another non-drug intervention suitable for routine outpatient care. Among the hypnosis methods practiced in France, E2R (Emotion, Regression, Repair) is a hypnotherapy method used in general practice, particularly for chronic insomnia. To date, no clinical trials have been carried out to demonstrate its effectiveness in this pathology.

The HypERR study is a multicenter, randomized, open-label study designed to evaluate the efficacy of a hypotherapy method called E2R in the management of chronic insomnia, by comparing it with standard care (without hypnosis).

The selection and inclusion of patients will be carried out by 34 GPs (General Practitioner), the study investigators. They will then randomize their patients into one of 2 groups: the E2R hypnosis group versus the "standard care" control group (without hypnosis).

Patients randomized to the hypnosis group will be referred by their GP to a hypnotherapist in their area within a 30-minute radius. They will receive 4 x 30-minute hypnotherapy sessions over 6 weeks.

For patients randomized to the control group, the GP will be free to implement psychotherapy and/or other non-medication interventions as usual (with the exception of hypnosis) and/or medication.

Then, all patients will be reviewed at 3 and 6 months by their GP (+/- 1 week) after randomization (D0) to assess the study criteria.
