Given the growing importance of placing the patient at the heart of care evaluation, the use of patient questionnaires such as Patient Reported Experience Measures (PREMS) or Patient-Reported Outcome Measures (PROMS) has become widespread in recent years. PROMS assess the outcomes of care, whereas PREMS assess the patient's experience of care. However, these tools only imperfectly reflect the patient's experience and only answer specific questions: satisfaction, pain management, waiting times, etc.

Patients undergoing bariatric surgery will undergo major surgery that will have an impact on their subsequent quality of life. Preparing for this surgery is a lengthy process, involving various forms of support: psychological, nutritional, physical activity, and so on. Exploring patients' experiences in depth, based on their account of their care experience, can enable carers to better understand and apprehend this type of journey from a perspective closer to that of the patient.

The narrative inquiry method enables patients' unique experiences to be collected and co-constructed with the help of interviewers. In addition, this qualitative approach focuses not only on the experience of individuals, but also on the social and cultural aspects in which they are embedded, enabling a more global and less reductive approach to the patient experience.
