Résumé : Introduction : Management of COPD patient involves medical, pharmacological, physical rehabilitation and lifestyle interventions, requiring a multidisciplinary approach. COPD patients may feel helpless when faced with all this information and the necessary changes. Methods : A qualitative study, using semi-structured telephone interviews, was conducted with COPD patients to identify their expectations about a mobile application to help them manage their disease. The interviews were registered, transcribed and coded using Nvivo. Results : The main motivation of the 20 patients included in the study was to help and contribute to research. Most patients (17) mentioned difficulties with their disease or with their treatment management, sometimes due to a lack of information. A quarter of patients believed that a mobile application could be useful to improve their knowledge of their disease and their medications. They also felt it could appease them, for example, about crisis management. According to the patients, a mobile application intended for them should contain, for example, information on COPD and its treatments or videos in order to perform breathing exercises. The application should also allow to be in contact with their healthcare professionals or with other COPD patients. Indeed, one of the most cited issues about communication was the unavailability of healthcare professionals. Several patients (6) mentioned that they had no barriers to using a mobile application developed to help them manage their disease. While the most frequently cited barriers were difficulties to use smartphones and the management of their personal data. Conclusion :COPD patients are receptive to the use of a mobile application to help them manage their disease. They feel isolated and see through this application a tool to improve their communication with the professionals around them but also with other COPD patients. They want to have access to personalized information and be reassured in certain situations.
