Project background & objectives

In France, chronic respiratory diseases represent a major public health issue, affecting 10% of the population, with a higher prevalence among women.

Asthma affects almost 4 million people, resulting in 60,000 hospitalizations and almost 1,000 deaths every year. Chronic obstructive pulmonary disease (COPD), meanwhile, affects around 3.5 million people, with a worrying under-diagnosis rate: almost 70% of cases remain unidentified. By 2030, COPD will be the third leading cause of death worldwide.

In this context, the CUB Trajectory cohort has been set up to better understand and combat these pathologies. Its aim is to include patients with COPD or asthma, in order to assess the effectiveness of existing treatments, identify associated risk factors and optimize care pathways for patients suffering from chronic bronchial diseases.

            Why take part in the project?

            Some of your medical and administrative data is collected when you are treated in a healthcare facility. This data is useful for the advancement of research.

            This research, conducted in the public interest, aims to develop knowledge in order to develop new treatments or improve the overall management of patients suffering from the same disease as you. If you agree to your data being used for this study, you will not have to make any additional visits or undergo any additional examinations.

            Only information already in your medical file will be collected. No directly identifying data (surname, first name or contact details) will be included in the cohorts.
