Chronic obstructive pulmonary disease (COPD) is a chronic disease with a high prevalence in France, but which remains under-diagnosed due to the trivialization of symptoms and difficulty in accessing diagnostic investigations. It is associated with other co-morbidities, with an impact on the occurrence of complications and quality of life. Early management of the most severe patients would allow better control of these risks of complications. Our objective is to better identify patients with COPD at risk of complications in general practice, taking into account the totality of the patient, to improve their management.
