Impact of Hypnosis Intervention on the Emotional Dimension of Dyspnea in Patients With COPD.

Impact of Hypnosis Intervention Focused on the Emotional Dimension of Dyspnea on the Maintenance of Benefits for Patients With COPD After a Pulmonary Rehabilitation: A Multicenter Randomized Controlled Clinical Study

The purpose of the clinical study is to compare the effect of hypnosis intervention on the emotional dimension of the dyspnea during a pulmonary rehabilitation program to the pulmonary rehabilitation program alone. This study will determine if the hypnosis intervention will lead to better maintenance of benefits obtained than the original described method.

Study Overview

• Status: Completed
• Conditions: Chronic Obstructive Pulmonary Disease
• Intervention / Treatment: Other: Hypnosis intervention focused on the emotional dimension of the dyspnea

Detailed Description

While physical activity level is the best predictor of life expectancy for patients with chronic obstructive pulmonary disease (COPD), the majority of patients have physical activity levels well below guidelines. One of the main barriers to regular activity is anxiety related to dyspnea. Defined as a subjective experience of discomfort during breathing, dyspnea is described as a multidimensional phenomenon integrating both the impact dimension (daily disability), the sensory dimension (intensity of dyspnea) and the emotional dimension (unpleasant and anxiety-aspects). The most effective treatment to reduce dyspnea is pulmonary rehabilitation. An overall improvement in dyspnea, and more specifically in its emotional dimension, has been achieved by reducing dyspnea anxiety. By reducing one of the major barriers to regular physical activity, the level of post-rehabilitation physical activity should also be improved. However, paradoxically, many studies have reported that there has been no change in the level of physical activity of patients in post-rehabilitation. A possible hypothesis to explain this decoupling between the improvement of the emotional dimension of dyspnea and the absence of behavioral modification, lies in the disappearance of the effects once at home. Indeed, during a pulmonary rehabilitation stay, patients practice under health professionals' supervision and advices with regular feedback on their abilities. When patients return home left on their own again, dyspnea anxiety is likely to reappear and motivation may not be enough.

Several techniques have been proposed to complement traditional interventions in order to strengthen rehabilitation effects. Unfortunately, these are not effective. The use of hypnosis as a complement to rehabilitation programs is a promising perspective to maintain the benefits on the emotional dimension of dyspnea after a rehabilitation program. Its benefits have already been demonstrated in the reduction of acute and chronic pains, in a long-term effectiveness using self-hypnosis techniques. These ensure the continuity of remote management of the intervention. Given the analogy between pain and dyspnea, hypnosis could therefore constitute a therapeutic solution as a complement to rehabilitation to durably reduce dyspnea anxiety in patients with COPD, and promote a better behavior at middle and long term.

The investigators hypothesize that hypnosis used in addition to a 4-week pulmonary rehabilitation program will maintain the benefits on the emotional dimension of dyspnea at 6 months in the experimental group compared to a control group.

The main objective is to evaluate the impact of a hypnosis intervention during a pulmonary rehabilitation program on the emotional dimension of dyspnea 6 months after patients return home (T2).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Hypnosis Arm; In parallel with an inpatient pulmonary rehabilitation program, nine visits will be carried out : V0 : an inclusion visit; V1 : a randomization visit; V2 to V6 : five visits with hypnosis sessions; V7 : a end-stay visit; V8 : a 6-month post-rehabilitation visit ( by phone call) The five hypnosis sessions (V2 to V6) will be spread over three weeks of rehabilitation program (1 to 2 hypnosis sessions per week). For V1, V7 and V8 : questionnaires will be filled about : quality of life (CAT questionnaire), the three dimensions of dyspnea (mMRC, LCADL and MDP questionnaires), anxiety and depression (HADS questionnaire), post-traumatic stress ( PCLS questionnaire), sedentarity and physical activity (SIMPAQ questionnaire). Other data will be also collected on : previous experiences with hypnosis, self-hypnosis and relaxation, number of exacerbations and hospitalizations in the past 6 months, drug treatment, psychotropic drug use and dosage and psychological follow-up.	Other: Hypnosis intervention focused on the emotional dimension of the dyspnea; Individual hypnosis sessions will be for 1 hour. Each hypnosis session will be standardized and evaluated using a script and an observation grid ( Visual Analogic Scale comfort, patient's hypnotic state...) written in collaboration with experts from Institut Milton Hyland Erickson Toulouse France (IMHETO).
No Intervention: Control Arm; In parallel with an inpatient pulmonary rehabilitation program, no additional intervention will be carry out and four visits will be carried out : V0 : an inclusion visit; V1 : a randomization visit; V7 : a end-stay visit; V8 : a 6-month post-rehabilitation visit ( by phone call) For V1, V7 and V8 : questionnaires will be filled about : quality of life (CAT questionnaire), the three dimensions of dyspnea (mMRC, LCADL and MDP questionnaires), anxiety and depression (HADS questionnaire), post-traumatic stress ( PCLS questionnaire), sedentarity and physical activity (SIMPAQ questionnaire). Other data will be also collected on : previous experiences with hypnosis, self-hypnosis and relaxation, number of exacerbations and hospitalizations in the past 6 months, drug treatment, psychotropic drug use and dosage and psychological follow-up.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Differential of the emotional dimension of dyspnea 6 months after pulmonary rehabilitation (PR)	Assessing differential of the emotional dimension of dyspnea score on the Multidimensional Dyspnea Profile scale (MDP questionnaire Meek et al 2012) 6 months after pulmonary rehabilitation (PR). MDP is a 11 items questionnaire. Each item is graded 0-10. 5 items are devoted to the emotional dimension of dyspnea. High scores indicate high prevalence of symptoms. As proposed by Morélot-Panzini et al in 2016, for filling it up, patient will be asked to focus on his worst dyspnea experience that happened oin the last two weeks.	Change from baseline (T0) to 6 month follow-up (T2)

Differential of the impact dimension of dyspnea	Assessing differential of the impact dimension of dyspnea score on the modified Medical Research Council scale ( mMRC questionnaire) and on the London Chest of Activity Daily Living (LCADL) at the PR end-stay and 6 months after PR. mMRC is a 1 item questionnaire graded 0-4. High score indicates high prevalence of symptoms. LCADL is a15-item, self-administered questionnaire which allows an evaluation of dyspnea in patients with COPD during daily activities divided into four components: self-care, domestic, physical, and leisure. Patients could score from 0: "I would not do anyway" to 5: "I need someone else to do this". LCADL score is calculated by aggregating the points assigned to each question, with a higher score representing maximal disability.

MDP is a 11 items questionnaire. Each item is graded 0-10. 6 items are devoted to the sensory dimension of dyspnea. High scores indicate high prevalence of symptoms. As proposed by Morélot-Panzini et al in 2016, for filling it up, patient will be asked to focus on his worst dyspnea experience that happened oin the last two weeks.	Changes from baseline (T0) to at the end of the 4-weeks PR (T1) , from T0 to 6 month follow-up (T2) and from T1 to 6 month follow-up (T2)
