There is no longer any point in continuing the research, as the objectives and evaluation criteria defined in the protocol are now being evaluated in everyday practice.

The aim of this study is to assess the impact of the Patient Therapeutic Education (PTE) workshops offered by the Maison de Prévention de la Santé et d'Accompagnement Thérapeutique (MPSAT) on the follow-up and feelings of the COPD patients who take part. These workshops are organised outside the hospital environment and supervised by hospital and town professionals in the NOVO zone.

In France, the ageing of the population (around 20% of the population is aged 65 or over), coupled with medical advances, lifestyle changes and environmental problems, is leading to an increase in chronic diseases, which are responsible for the majority of deaths.

Chronic obstructive pulmonary disease (COPD) is one of the most widespread chronic diseases in France. The departments most affected by COPD in terms of prevalence and (underestimated) mortality are the most vulnerable: Seine-et-Marne (77), Val-d'Oise (95) and Seine-Saint-Denis (93).

In the field of nursing, patient therapeutic education workshops (PTE) are an approach that aims to improve patients' health and well-being by actively involving them in managing their own health. The Maison de Prévention de la Santé et d'Accompagnement Thérapeutique (MPSAT), an innovative structure, seeks to promote this new approach by improving the management and care of COPD patients. In this context of changes in the management of the care pathway for chronic patients, one of the essential actions is therefore to actively involve the patient in the follow-up and to provide them with the means to understand their pathology: the main focus of this work will be on this crucial stage which is Patient Therapeutic Education (PTE). However, in 80% of cases, PTE programmes are developed almost exclusively in public hospitals. The PTE workshops run by the MPSAT, which take place outside the hospital, are fully justified here. The MPSAT, that will be at the heart of this research project, aims to promote this new approach by improving the management and care pathway for COPD patients.

The aim of this study is to answer the following question : in the context of developments in the management of patients suffering from chronic diseases in France, and in particular COPD, what is the impact of the MPSAT's therapeutic education workshops, organised outside the hospital environment and supervised by professionals from both the hospital and urban environments of the NOVO territory, on the COPD patients who take part in them?
